Description

Sewing process and processing equipment for sewing product and sewing product obtained by processing sewing process and processing equipment

Technical Field

The present invention relates to sleeping bags, garments, and methods and apparatus for making such sewn products as sleeping bags, garments, and blankets and mattresses, and more particularly to sleeping bags, and garments and automated, mass and low cost manufacturing methods and apparatus therefor.

Background

How to realize full-automatic sewing of soft, easily deformable and easily wrinkled cloth is always a field which is widely researched in the automation field but has not obtained obvious results.

In order to achieve the purpose of accurate positioning and accurate control, an automatic sewing company represented by the American Sewbo company proposes the following technical scheme: the cloth is sized and/or frozen to harden the cloth into a plate-shaped structure with certain rigidity and hardness, so that the original soft and easily deformable and/or elastic cloth is changed into a plate-shaped structure with certain rigidity and hardness similar to a metal plate, a plastic plate and the like, so that the identification, control, alignment and sewing of a computer are facilitated, and the cloth is softened, dissolved and removed with the pulp or the serous fluid after the sewing is finished. Such a solution is certainly feasible, but the cutting pieces are respectively blanked and then sent to a machine table, and the equipment cost is very high, so that the size or the liquid which can be suitably sized, solidified, softened, dissolved and removed with the cloth without affecting various dyeing/printing patterns of the cloth is limited. Companies represented by Softwear Automation in the united states propose the use of high-precision cameras and intelligent systems (seebots), which, although feasible, are extremely expensive in equipment cost, and can only be used as products with simple structures such as T-shirts, and cannot be used as thick-material products such as filling layers at all.

The existing sleeping bags, clothes, bags or cushions, especially sewing products with zippers or VELCRO (VELCRO, magic tape, magic buckle, burr buckle, etc.), generally lay out and stack coiled raw materials into multiple layers, then cut the layers, and sew different cut pieces together by sewing machines operated manually, which is labor-consuming and has poor reliability and consistency of manual operation.

For example, prior art sleeping bag manufacturing processes are generally as shown in the process diagrams of FIG. 13 or FIG. 14: fig. 13 shows an earlier common process: firstly, respectively stacking and stretching the fabrics and the linings on a long cutting bed in multiple layers (spreading), and then respectively cutting the multilayer fabrics and the linings into required shapes (blanking); sewing the cut single-layer fabric and lining into a bag-shaped structure which is inverted inside and outside (the outer surface of the sleeping bag is in the bag-shaped structure, the inner surface is outside the bag-shaped structure, the outer surface is outside, the inner surface is inside through the subsequent bag turning process), and sewing the zipper of the sleeping bag in the bag-shaped structure along part or all of the sewing line edges (the zipper is also sewn in the bag-shaped structure, and the zipper is turned outside the bag through the subsequent bag turning process); then the bag-shaped structure is turned inside and outside (also called as a bag turning over); filling filler (various fillers for heat preservation including cotton, chemical fiber, down feather and the like) into the turned bag-shaped structure; then quilting the fabric layer, the filling layer and the lining layer which are approximately uniformly overlapped and flattened to fix the filler, so that the fabric layer, the filling layer and the lining layer are integrated to avoid the phenomenon that the filling layer has larger displacement or filler leak in the using process to influence the heat insulation effect of the sleeping bag; then sealing the filled bag-shaped structure; finally, the procedures of quality inspection, packaging and the like are carried out. With the development of the technique of fixing cotton such as the collodion cotton, a common process used in recent years is shown in fig. 14: firstly, respectively stacking and stretching the fabric, the lining and the filling layer on a long cutting bed or the ground in multiple layers, and then cutting the materials stacked in multiple layers into required shapes; sewing the cut single-layer fabric and lining into a bag-shaped structure which is inverted inside and outside (at the moment, the outer surface of the sleeping bag is in the bag-shaped structure, the inner surface of the sleeping bag is outside the bag-shaped structure, the filling layer is also outside the bag-shaped structure, the outer surface of the sleeping bag is required to be outside through a subsequent bag turning process, and the filling layer and the inner surface of the sleeping bag are inside the bag-shaped structure), and the zipper of the sleeping bag is sewn inside the bag-shaped structure along part or all of the edges of the sewing thread when the bag-shaped structure is sewn (at the moment, the zipper is also sewn inside the bag-shaped structure, and the sleeping bag is; then the bag-shaped structure is turned inside and outside (turning over the bag); then quilting the fabric layer, the filling layer and the lining layer which are approximately uniformly overlapped and flattened to fix the filler, so that the fabric layer, the filling layer and the lining layer are integrated to avoid the phenomenon that the filling layer has larger displacement or filler leak in the using process to influence the heat insulation effect of the sleeping bag; then sealing the filled bag-shaped structure; finally, the procedures of quality inspection, packaging and the like are carried out.

The existing sleeping bags are produced by a large amount of manpower (particularly sewing workers which are increasingly expensive nowadays), the production process is complicated and tedious, the steps are multiple, the production efficiency and the automation degree are low, and the wage cost is high; and the zipper sewing and bag turning are indispensable and must be finished manually at present, greatly influencing the production efficiency and increasing the labor cost.

The production process of the existing clothes with the filling layer (the warm-keeping layer) is basically the same, and as sleeves, necklines, pockets, buttons and the like are needed, the process is more complicated, the working procedures are more, more labor is consumed, and the production efficiency is lower.

The existing production process of carpets, blankets or picnic mats and the like also comprises the steps of cutting uncut raw material rolls to obtain cut pieces, and then binding, curling or binding cut parts of the cut pieces. There is still a need for manual intervention in the production process.

Hemming barrels (also known as hemming pull barrels, hemers, hemming dies, hemming heads, hemming taps or hemming tools) and hemers (also known as hemming heads) are widely used as non-patent or overdue patent technologies in the sewing industry, and common sewing accessory shops and a large number of treasure-making net shops are sold; there are also a number of hemers, hemers or serers that are used with flatcars for reference and selection of patent technologies, such as chinese patent application nos. 201810517529.9, 201810127043.4, 201610132359.3, 201320581021.8). Such as the technical solutions shown in chinese patent application nos. 201410348141.2, 201320017156.1, 201320517381.1, 201620167334.2, 201610738792.1, 201710910325.7. The technology of 'curling/edge covering/serging/overlocking + zipper' of the patents or non-patents is applied to the flat car, but the technology of 'curling/edge covering/serging/overlocking + zipper' is not applied to the quilting machine head at the same time. Because, the traditional quilting machine takes the needle to penetrate the body in the middle of the body as the design function, and does not consider other functions such as edge sealing, zipper mounting and the like.

Therefore, under the circumstance that the labor cost is increasingly high, how to provide a method and equipment which are similar to an automatic computer quilting machine and can realize that the material enters and the finished product comes out, the middle production process is manual zero intervention, so as to reduce the labor cost and improve the production efficiency, and the mechanized and automatic production of products such as sleeping bags, clothes with filling layers, blankets and/or cushions and the like is a problem to be solved by the technical personnel in the field.

Disclosure of Invention

In view of the above, the present invention at least solves the problems that a plurality of devices are needed to process sleeping bags, clothes, bags or cushions in a plurality of processes, that is, cloth is cut off first and then spliced and sewn by a sewing machine operated manually, which results in labor and time waste and poor reliability and consistency of manual operation.

The invention provides a sewing process of a sewing product, processing equipment of the sewing product and a sleeping bag, a bag or clothes prepared by the processing equipment of the sewing product.

In order to achieve the purpose, the invention adopts the following technical scheme:

an object of the present invention is to provide a sewing process of a sewn product,

step (1): the sewn material and the sewing thread which are not cut are arranged on a machine, and the sewn material is spread to the position to be cut;

step (2): the sewing material at the position to be cut is fixed by the fixing mechanism, then the cutting machine head is used for cutting the sewing material according to the preset shape, the root part of the cut sewing head is fixed by the fixing mechanism in a mode that the sewing head and the fixing mechanism can not move relatively so as to ensure the accurate alignment and positioning of the sewing head part (and the root part of the fixed sewing head can move integrally along with the fixing mechanism to match the movement of the cutting machine head and/or the edge bonding machine head and the like when necessary); when or after the material to be sewn is cut into the preset shape of the body initial product which can include curves by using the cutting machine head, the edge sealing machine head behind the cutting machine head is used for synchronously sealing and sewing the edge of the material to be sewn, and a finished body product is obtained.

The invention has the beneficial effects that: according to the sewing process, the sewn material and the sewing thread are simultaneously fed on the machine and spread to the position to be cut, and are simultaneously cut, and then the edge of the sewn material is sealed by the edge sealing machine head and the sewing machine head is utilized to perform sewing.

The sewing process of the sewing product comprises the following steps that the sewing material at least comprises more than two layers of sewing materials of lining materials and surface materials, and the more than two layers of sewing materials are overlapped and spread to the position to be cut.

The invention further discloses a zipper, a nylon fastener tape and/or a rope tape, wherein the zipper, the nylon fastener tape and/or the rope tape are distributed to an edge sealing machine head through a distribution mechanism, and are positioned at the edge sealing position of a cutting fracture of a sewn material through the edge sealing machine head to be sealed and sewn synchronously, so that a finished product of a body is obtained. For example, a zipper necessary for a sleeping bag or a bag, a rope (drawstring) at a drawstring position of a drawstring bag, a core belt with a core hem, a zipper or a velcro tape on clothing, and the like can be manufactured.

It should be noted that: the description of "simultaneous sealing, sewing" or "sewing together" in this specification shall include not only the case where the needle thread penetrates the zipper cloth of the zipper or the velcro tape to fixedly sew them to the sealing position, but also the case where the drawstring of the drawstring bag is wrapped in the hem structure of the mouth of the drawstring bag but is not fixedly sewed by the sewing thread and the drawstring hem structure (if the two are fixedly sewed, the drawstring cannot be drawn out or pulled in the drawstring hem structure, that is, the drawstring bag cannot be drawn). Such situations are summarized in this description generally by the description of "simultaneous banding, sewing" or "stitching together".

The adoption of the further beneficial effects is as follows: the sewing of two layers of materials, the zipper, the nylon button and/or the rope belt can be realized only through the integrated edge sealing and sewing processes, the bag body or the garment body can be obtained by synchronously pulling up the zipper, sewing the nylon button, sewing the drawstring and/or sewing the braid, and the like, and the process that the zipper, the nylon button and/or the rope belt is sewn on the body by manually operating the sewing machine is not needed to be arranged like the prior art. The manufacturing process is simple, and the product consistency is high.

The sewing process of the sewing product can further comprise filling materials. Taking the sleeping bag as an example, the filling material is arranged between the fabric and the lining material and is simultaneously put on the machine, and the fabric and the lining material are synchronously cut into a preset shape by using the cutting machine head.

The sewing process of the sewing product further comprises a wind shielding strip, an anti-blocking strip and/or a label, wherein the wind shielding strip, the anti-blocking strip and/or the label and zipper cloth, a nylon buckle and/or a rope belt of a zipper are synchronously positioned at the cut part by the edge sealing machine head and are synchronously subjected to edge sealing and sewing.

The invention also provides a processing device of a sewing product, which comprises a main frame, a machine head mounting frame, a controller, a cutting machine head, an edge sealing machine head and a sewing machine head, wherein the cutting machine head is arranged on the machine head mounting frame and is used for cutting the fabric and the lining (taking the sleeping bag as an example) at the same time, the edge sealing machine head is used for synchronously positioning and sealing the zipper or the nylon fastener and the fabric and the lining at the cutting gap, the sewing machine head is used for sewing the zipper or the nylon fastener and the fabric and the lining at the cutting gap, and the machine head mounting frame is connected to the main frame in a; the handpiece mounting rack can adopt a mechanical arm form, and if the mechanical arm is long enough, the mechanical arm can also be fixedly mounted on the main frame or beside the main frame; the cutting machine head, the edge sealing machine head and the sewing machine head are slidably and rotatably arranged on the machine head mounting frame or the mechanical arm, and the controller controls the cutting machine head, the edge sealing machine head and the sewing machine head to synchronously cut edges and seal edges.

In the case where the sewn material has been fixed, the cutting process and the hemming/serging process may be performed simultaneously, i.e., hemming/serging is performed while cutting, with the hemming/serging mechanism following the cutting mechanism; the two steps can be carried out in steps, namely, the cutting step is firstly completed, the cutting machine head is moved away, or the cloth translation mechanism is utilized to carry out the curling/edge covering/edge locking steps on the body primary products which are cut together. The two techniques are not very different from each other in nature, but the former has more advantages in preventing the fracture from being loosened and disordered, and in technical realizability and reliability.

The processing equipment for the sewing product is characterized in that the cutting machine head, the edge sealing machine head and the sewing machine head sequentially form a three-head integrated machine head and are connected to the lower end of the same rotating rod, and the upper end of the rotating rod is connected to a machine head mounting frame in a sliding manner; or the edge banding machine head and the sewing machine head are sequentially combined into a two-head integrated machine head which is connected with the lower end of the same rotating rod; or the cutting machine head, the edge sealing machine head and the sewing machine head are respectively and correspondingly connected to the lower end of a rotating rod, and the processes of edge cutting, edge sealing and sewing are carried out.

The processing equipment for the sewing product is characterized in that the main frame is provided with a cloth bearing platform, and fine holes are densely distributed on the cloth bearing platform; an air exhaust or blowing device is arranged below the cloth bearing platform, and an air exhaust port or an air blowing port on the air exhaust or blowing device is communicated with the fine holes.

The invention further provides a processing device of a sewing product, wherein the main frame is a computer quilter frame and comprises two guide rails and a quilting base which are arranged along the cloth direction, and the lower parts of the two ends of the machine head mounting frame are correspondingly connected with the guide rails in a sliding manner; a roll shaft for conveying cloth is connected between the two guide rails; the quilting base is arranged corresponding to the positions of the cutting machine head, the edge sealing machine head and/or the sewing machine head.

The processing equipment for the sewing product further comprises an upper material pressing frame and a lower material pressing frame, wherein the upper material pressing frame and the lower material pressing frame are movably connected to the machine head mounting frame through mechanical arms in a positioning mode and are used for performing edge cutting, edge sealing and sewing processes after passing cloth is fixed.

The processing equipment for the sewing product is characterized in that the three-head integrated machine head is more than two groups and respectively performs the processes of edge cutting, edge sealing and sewing.

The invention relates to a processing device of sewing products, further, the edge sealing machine head is a taping machine head or a serging machine head or a curling machine head, the taping machine head is provided with a taping tube, the curling machine head is provided with a curling tube, and the taping tube and the curling tube are provided with through holes which penetrate through the upper surface and the lower surface and are used for sewing by a sewing needle on the sewing machine head (of course, the sewing needle on the sewing machine head can sew after following the taping tube or the curling tube instead of arranging the through holes for the needle thread to penetrate through the taping tube or the curling tube; or the like, or, alternatively,

the curling machine head is provided with a curling folded plate, the rolling folded plate comprises a curling transverse plate and a curling vertical plate, and cloth arranging brushes are arranged at the positions of the curling transverse plate along the front side and the curling side of the cloth conveying direction.

According to the processing equipment for the sewing products, one side of the machine head mounting frame is provided with the limiting hole, the zipper, the nylon fastener tape and/or the rope belt penetrate through the limiting hole and are conveyed into the edge covering barrel or the hemming barrel under the pushing or pulling action of the teeth of the base of the sewing machine head, and the zipper, the nylon fastener tape and/or the rope belt are sewn together with the lining and the fabric through the through hole through the sewing needle on the sewing machine head.

The processing equipment for the sewing product is characterized in that a zipper arrangement plate is further arranged on one side, close to the fabric or lining, of the edge covering cylinder and the hemming cylinder, and the distance between the zipper arrangement plate and the bottom surface of the edge covering cylinder and/or the hemming cylinder is suitable for penetrating of zipper cloth of the zipper and is smaller than the height of zipper teeth of the zipper.

The processing equipment for the sewing product further comprises a zipper distributor, wherein the zipper distributor is distributed at the front side of the edge covering cylinder, the hemming cylinder and/or the serging machine head and comprises two horizontally arranged strip-shaped positioning plates, and the distance between the strip-shaped positioning plates is greater than the height of zipper teeth of a zipper; the strip-shaped positioning plates are connected through the sealing plate along one side in the length direction, the openings on the other side are necking towards the side close to each other, the width of each necking is provided for the zipper cloth of the zipper to penetrate through and penetrate out, the height of each zipper tooth is smaller than that of the zipper, and the zipper teeth of the zipper are positioned between the two strip-shaped positioning plates.

The zipper arrangement plate or the zipper arrangement device utilizes the characteristic that the zipper cloth is different from the zipper teeth in thickness, so that the zipper cloth can penetrate through the manufactured structures such as the rigid clamping groove, the clamping seam or the bayonet and the like, and the zipper teeth cannot penetrate through the structures, thereby realizing the positioning of the conveyed zipper, and facilitating the accurate sewing of a subsequent sewing machine head. Since the above description is made by taking a sleeping bag zipper as an example, the above layout plate or layout device is called a "zipper layout plate" or a "zipper layout device", but the layout plate or layout device is not limited to the layout of a zipper, and can be converted into a corresponding rope layout device, a belt layout device, a Velcro layout device, and the like, by replacing the rigid slot, the card slit, the bayonet, and the like, which are matched with the zipper structure, with the slot, the card slit, the bayonet, the limiting hole, and the like, which are matched with the cross section of a rope, a belt, a zipper (i.e., a piece of non-cut Velcro), and the like.

In the invention, the edge sealing machine head and the sewing machine head are arranged on a frame and are arranged close to or integrally, namely, the hemming barrel/edge covering barrel/overlock device arranged at the sewing machine head and the zipper arrangement device are added, so that the synchronous and integrated sewing of cloth hemming, edge covering or serging and the zipper can be realized. The invention enables the zipper cloth to be rolled into the curling barrel or between the cloth turned up by the curling barrel and then synchronously conveyed to the space between the sewing needle and the rotating shuttle for sewing. That is, when the cloth bending channel of the hemming tube or the hemming tube with stainless steel or stainless steel as the main body is manufactured, the zipper channel is welded on the cloth bending channel, so that the zipper and the bent cloth are fed below the hemming/hemming sewing thread together, and the hemming/hemming sewing thread simultaneously passes through the folded cloth and the zipper cloth of the zipper, thus forming the hemming/hemming structure with the zipper.

The laying mechanism not only can lay and position the label, the zipper or the nylon fastener at the cut part of the sewed material, but also is provided with an automatic shearing device for shearing the label, the zipper or the nylon fastener according to the preset length and/or position. In particular, labels, which are typically only a few centimeters to a few tens of centimeters long and wide after being sewn to the finished product, are produced in rolls of hundreds, thousands or even tens of thousands of labels produced by printing or labeling mills when they are transported to the apparatus of the present invention; the apparatus of the invention therefore produces a continuous plurality of labels intermittently fed to the head: when the edge sealing machine head does not operate to the position where the labels are to be sewn, the conveying device does not operate although the label cloth strips where the single labels are located are still connected to the label conveying device, and the labels cannot be conveyed into the edge sealing machine head; however, once the edge sealing machine head runs to the position where the label is to be sewn, the label conveying device under the control of the computer starts to run immediately, and the label cloth strips where the single labels are located are conveyed to the edge sealing machine head, so that the edge sealing machine head can sew the labels to the edge sealing position together, and the purpose of feeding the labels is achieved; and once one or a group of labels are conveyed according to the length and the position preset by the computer, the label conveying device under the control of the computer stops conveying the labels to enter a standby state again immediately, and a new conveying period is started again and again when the edge sealing machine head moves to the position where the labels are to be sewn next time.

The processing equipment for the sewing product further comprises a presser foot, wherein the presser foot can be lifted and pressed on the fabric and is positioned on two sides of a cutter of the cutting machine head or the rear side of a curling barrel of the curling machine head, or the rear side of a hemming barrel of the hemming machine head, or two sides of a sewing needle of the sewing machine head.

The invention also provides a sleeping bag, a bag or a garment, which is processed by the processing equipment of the sewing product and comprises a layer of material or more than two layers of material and at least one zipper or nylon fastener, wherein the zipper and/or nylon fastener connects the at least one layer of material into a cylindrical or bag-shaped structure for accommodating human bodies or objects;

the sleeping bag, bag or garment body may be flattened flat, fold-free and wrinkle-free onto a flat surface before the zipper and/or velcro is in the attached state or after the zipper and/or velcro is fully opened. Of course, in order to prevent others from misinterpreting the contents of the present specification in the form of "diamond horn tip" in the literal sense of simple characters, special emphasis is placed on: the term "spread without folds and wrinkles" as used herein means that the finished body product itself is not folded or wrinkled after being spread, and does not mean that the finished body product is not folded or wrinkled, which is required to be a little cloth. The latter is not practical for sewing products because the hemming and hemming are accomplished by folding and folding the fabric and sewing. Folds and creases in the sewn fabric (e.g., sewn hems or the hem structure itself) in the upper portion of the finished body are unavoidable and will persist even after sewing, even if the finished body is flattened. The folding and wrinkling of the fabric portions caused by the sewing process itself are not intended to be the folding or wrinkling of the unfolded body product as referred to in this specification or claims.

The invention further provides a sleeping bag, a bag or a garment, wherein at least two layers of materials are superposed and then simultaneously cut at one time to obtain a body primary product, and projection lines of cut fractures of all layers of the body primary product can be simultaneously superposed into the same projection line before being sewn; the zipper and/or the nylon fastener tape and the at least one layer of material are simultaneously sewn together at one time through a sealing edge structure comprising a wrapping edge, a curling edge or a binding edge.

The sleeping bag, bag or garment of the invention comprises at least one layer of material and at least one connector comprising a zipper or velcro, which connects the at least one layer of material into a tubular or bag-like structure for receiving a person or object, and which can be flattened flat without folds and wrinkles onto a flat surface before the connector is in the connected state or after the connector is fully opened. The material of at least one layer, especially the material of multiple layers of superposition, is obtained by cutting at the same time in one time, and the projection lines of the cutting fractures of all layers can be coincided into the same projection line before being sewed; the zipper and/or the nylon fastener tape and the at least one layer of material are sewn together at the same time in a disposable mode.

The emphasis is given to the fact that "can be flattened without folds and without folds on a plane" is suitable for being automatically produced in one step on a plane or on a set of roll surfaces: the prior clothes are simple structures such as T-shirts, vests, waistcoats, underpants, short skirts and short sleeves, and relatively complex structures such as shirts, jackets, winddresses, suits, cotton-padded clothes, cotton-padded trousers and down jackets, because the fabric is made by folding and sewing the front and back pieces or the single piece, after being spread on a plane, the fabric always has folding parts (namely, at least two layers of front and back fabrics corresponding to the front and back of the human body always exist, and the two layers of fabrics are connected together through the folding lines, if the connecting mechanism comprising the zipper or the nylon fastener needs to be installed, the connecting mechanism can be realized only by processing modes of manual participation such as flat car or even three-dimensional sewing, and if the front and back cut pieces of the parts such as the shoulders, the crotch and the like are asymmetrically sewn together, the front and back cut pieces cannot be flattened after being spread on a plane, and wrinkles exist.

However, the fact that the finished garment of the present invention is "flat and flat without folds and wrinkles" means that the links, including zippers or velcro, can be directly pressed onto the processing platform (platform) for automatic, efficient and one-time sewing as in the following embodiments of the present invention; the steps of blanking (cutting), sewing pieces, sewing zippers and the like do not need to be carried out respectively; but one end of the machine is used for feeding, and the other end of the machine is used for directly discharging the finished product of the body; except for the need of starting and closing the machine and maintaining and patrolling from time to time, no manual work is needed.

In the existing garment or sleeping bag production process, cutting and sewing must be separately performed. Especially, the cloth or the filler has a double-layer or multi-layer structure, each layer of cloth or filler is cut separately, and then the materials cut separately are manually overlapped to carry out processes such as zipper and sewing. The fabric, the lining and/or the filler are integrally placed on the processing equipment, and are not required to be cut in advance and respectively, but are simultaneously superposed and cut at one time; and the sewing is carried out after the processing equipment cuts, so that not only is an independent blanking process not available, but also the processes of transportation, alignment and the like of the cut pieces after blanking are reduced, and a large amount of labor can be saved.

Furthermore, the cut pieces in the existing garment or sleeping bag production process are respectively cut, the cut parts inevitably have difference in size and shape to a greater or lesser extent, manual alignment cannot be completely consistent, and the cut pieces are fed into a sewing mechanism for sewing only by being roughly aligned according to experience, so that the phenomena of seam separation, under-seam and/or over-seam and the like are very easy to occur, and the product quality consistency is poor and even the sewing quality defect occurs. This is why a large number of skilled sewing workers are required. The multilayer superposed material is obtained by simultaneously cutting at one time, and the projection lines of the cutting fractures of all layers can be simultaneously superposed into the same projection line before being sewn; the fracture alignment can be ensured without an additional alignment process. Therefore, the sewing quality is better, the consistency is higher, and the efficiency is higher.

In addition, in the existing production process of clothes or sleeping bags, zipper cloth is firstly sewn on one layer of the fabric or lining, and then the layer of the sewn zipper is sewn with other layers; resulting in low production efficiency and high labor cost. The zipper and/or the nylon fastener tape and the materials of all layers are sewn together at the same time in one step; the production efficiency is high, the labor cost is low, and the quality is stable and the consistency is good.

Another objective of the present invention is to provide a sleeping bag, which comprises a fabric, a lining, a zipper, and a wrapping structure, a curling structure and/or a serging structure; stacking multiple layers of materials including the fabric and the lining, and simultaneously cutting the materials into a preset shape to obtain a body primary product; the edge-covering, edge-curling and/or edge-locking structure wraps the cutting fracture of the edge of the primary product of the body; zipper cloth of the zipper is clamped between the edge covering, the edge curling and/or the edge locking structure and the body primary product, and the edge covering, the edge curling and/or the edge locking structure and the body primary product are sewn together through sewing threads. The zipper may be a closed full length zipper structure covering the entire length of the edge break or a non-closed zipper structure covering only a portion of the length of the edge break.

Further, the filling material is spread between the surface fabric and the lining material and extends to the seam of the edge of the primary product or the fracture of the edge of the primary product.

Further, the structure of borduring is including the last layer of borduring that is located the surface fabric side, the lower layer of borduring that is located the lining side and the tip layer of borduring that is located body primary product fracture tip, and the free tip on going up layer of borduring and/or lower layer of borduring bends and extends and correspond to the tip layer of borduring and form and go up the bilayer structure of borduring and/or bordure bilayer structure down, goes up the bilayer structure of borduring/go up the layer of borduring, zip fastener cloth of zip fastener and bordure bilayer structure/down the integrative sewing of layer three of borduring down and form.

Furthermore, the filling material extends into the end edge covering layer and is integrally bent to the suture line.

Furthermore, the filler extends to the end portion edge covering layer and is integrally bent to the outer side of the suture line to form a filler bending section, the free end portion of the upper edge covering layer is bent and extends towards the end portion edge covering layer to form an upper edge covering double-layer structure, the filler bending section is located in the upper edge covering double-layer structure, and the upper edge covering double-layer structure, the filler bending section in the upper edge covering double-layer structure, the body primary product and the lower edge covering layer are integrally sewn through the sewing line.

The wind shielding strip, the anti-blocking strip and/or the label are positioned at the position, close to the zipper, of the edge covering structure layer and are clamped between the zipper and the edge covering structure and/or between the zipper and the fabric and the lining layer.

When the edge-wrapping or edge-curling structure is used as a wind-shielding strip, when the sleeping bag is zipped up for use, the wind-shielding strip covers the zipper teeth and the zipper cloth, so that heat leakage at the zipper teeth and the zipper cloth is reduced or prevented, and the wind-shielding strip has the function of the wind-shielding strip. Of course, the weather strip formed by the edge-wrapping or edge-curling structure can be positioned not only at the position where the zipper is arranged, but also at the position where the zipper is not arranged, such as the human body entrance of the bag-shaped structure of the sleeping bag, the neckline/cuff/armhole of the garment and the like. When the wind shielding strip is formed at the position of the human body inlet and outlet by the edge-wrapping or edge-curling structure, the phenomenon that outside cold air enters the inside of the sleeping bag through the human body inlet and outlet (namely, the shoulder and the neck of a user lying down) can be avoided or reduced, and the function of collar enclosure is achieved.

Preferably, the edge covering cloth can be cotton cloth or flannelette which has the same or better skin touch feeling with the lining of the sleeping bag; or the lock edge line is cotton thread, wool or wool which is in contact with the skin of the human body and has better touch feeling.

When the zipper is pulled up by the edge-wrapping or edge-curling structure serving as an anti-blocking strip, the common zipper head at the zipper of the sleeping bag can be prevented from occluding the lining and/or the fabric of the sleeping bag into the zipper head to be blocked, so that the zipper has no problems of being pulled up or unsmooth, and the like.

Of course, a separate weather strip and/or anti-blocking strip can be additionally arranged at the edge-covering or edge-curling structure and/or the zipper instead of the edge-covering or edge-curling structure serving as the weather strip and/or the anti-blocking strip.

Wherein various labels, which may also include washing marks, trademarks and/or warning marks, are stitched at the hems/lockstitching and/or zip cloths.

The invention relates to a method for manufacturing a sleeping bag, which comprises the following steps:

step 1, simultaneously loading the fabric, the lining and the filler on a machine;

step 2, synchronously cutting the fabric, the lining and the filling material into a preset shape to obtain a body initial product, sewing according to the sleeping bag, and synchronously cutting edge wrapping/curling/serging of a fracture and clamping a zipper to obtain a body finished product;

and finally, carrying out post-treatment processes such as inspection and packaging of the finished product of the body.

More specifically: the equipment for manufacturing the sleeping bag is used for simultaneously loading the fabric, the lining and the filler on the machine and synchronously cutting the fabric, the lining and the filler into a preset shape to obtain a body primary product, then sewing according to the sleeping bag, and synchronously cutting edge covering/curling/serging of a fracture and clamping a zipper to obtain a body finished product. The sleeping bag manufacturing equipment is obtained by modifying and adding a well-developed and reliable quilting machine in the prior art. Firstly, the fabric layer, the filling layer and the lining layer of the sleeping bag are sequentially overlapped and then are sent into a quilting mechanism to carry out quilting of a primary product of the body and/or sewing of the edge of the spread shape of the sleeping bag. Then, the edge fracture is cut to form a Seam head (Margin to Seam), and then hemming/lockstitching is performed for the air drop.

Furthermore, the accessory structures including the wind shielding strip, the anti-blocking strip and/or the label are synchronously clamped and sewn with the zipper cloth.

Because the fabric layer, the filling layer and the lining layer of the sleeping bag can be synchronously quilted and/or cut after being stacked in multiple layers, and the cotton filling process can be bypassed, and the manual bag turning process which is required to be used up to now is avoided, the production efficiency can be greatly improved, and the manual work, especially the skilled sewing worker, can be greatly reduced. The quilting on the primary product of the sleeping bag body, the fixing and/or sewing of the fracture of the edge of the sleeping bag, even the hemming, edge covering and edge locking processes can be completed by the same sewing machine or the same group of sewing machines after being provided with a suitable hemmer/hemmer; the production efficiency can be greatly improved, and the production cost can be greatly reduced. Moreover, under the condition that the automation control technology is highly developed, the quality stability, controllability and consistency of products produced by the machine under the accurate control of a computer are better.

The invention combines the zipper tube and the hemming tube (or the edge wrapping tube) together, and becomes a unique method and equipment for manufacturing the sleeping bag by simultaneously or synchronously carrying out zipper and hemming (or zipper and edge wrapping).

In the invention, the feeding, quilting, cutting, edge sealing, zipper feeding and the like are all integrated on the quilting machine, which belongs to the creative breakthrough. Of course, it is also possible to finish the edge wrapping, hemming or serging separately and then perform zipper sewing, but this becomes a common zipper, and the production efficiency and the aesthetic degree of the final product are affected.

Finally, the processes of loading the pull head, repairing the thread end, checking the product and/or packaging and the like are carried out. The processes of loading the slider, repairing the thread end, inspecting the goods and/or packaging can be completely manually executed, and can be realized by partial or whole automatic and intelligent processes under the premise of budget permission.

Furthermore, auxiliary structures including the wind shielding strips, the anti-blocking strips and/or the labels are synchronously clamped and sewn with the zipper cloth.

Preferably, when the width of the filling layer, the surface material and/or the lining material wrapped by the edge covering structure is larger, the larger strip-shaped edge covering structure formed by the edge covering structure can also be directly used as a wind shielding strip and/or an anti-blocking strip of the sleeping bag, and the wind shielding strip and/or the anti-blocking strip do not need to be specially arranged.

During the edge covering or curling process, a manufacturing method or equipment of 'sleeping bag immovable and edge sealing machine head moving' can be adopted, and a manufacturing method or equipment of 'sleeping bag movable and edge sealing machine head immovable' can also be adopted. The sleeping bag bearing platform can be fixed, but the edge sealing machine head with relatively small volume and weight bites the outer edge of the fracture of the sleeping bag in the pre-designed shape to move, the process is relatively simple, and the equipment is relatively easy to obtain; the latter is not difficult under the condition that the current bearing platform negative pressure air suction fixing technology or the blowing floating rotation technology is mature. The two methods should be selected in a most suitable way after being comprehensively considered according to specific requirements such as products, process requirements, investment budget and the like.

The cutting machine head can be a traditional circular knife or a vibration knife, and can also be used for laser cutting; the quilting can be wired quilting or wireless (ultrasonic welding).

The disposable sewing can be single-needle sewing, can also be double-needle or multi-needle sewing, and can even supplement one or more sewing threads after the disposable sewing is finished so as to strengthen the sewing fastness.

Certainly, under the condition that budget allows or processing technology needs, equipment or processes such as manufacturing, printing, marking, stamping, silk-screen printing, embroidering, quilting, cotton loosening, cotton carding, code spraying, marking, counting, sleeve feeding, bag opening, placket opening, button sewing, belt nailing, folding, rolling, bag plugging, automatic packaging and/or automatic storage and transportation and the like can be matched with or/and matched with the previous or subsequent automatic process or equipment, so that higher-degree and wider-range automation, streamline and intellectualization are realized.

Because the blanking program is integrated on the same machine, the machine can simultaneously perform optimized typesetting (interpenetration), optimization, blanking and the like only by combining with the traditional typesetting software, thereby avoiding or reducing material waste as much as possible.

The biggest challenge of automatic sewing is how to align and control soft cloth, filling materials and the like, and the identification and control capability of the edge sealing of the cutting opening is accurate to millimeter or sub-millimeter level, otherwise, the phenomena of seam separation, seam shortage, seam passing, deformation, distortion and the like are extremely easy to occur carelessly. This is why Sewbo et al, USA, have tried to size and/or freeze the cloth to harden it into a rigid and stiff plate-like structure. However, the solutions and equipment proposed by Sewbo et al are very costly and do not allow to bypass the blanking process, are suitable for sizing, curing and then re-softening, dissolving/removing the fabric and are practically limited in that they do not affect the various dyeings/printed patterns of the fabric at all.

The cutting process is simultaneously integrated into a set of device, two or more layers of materials are simultaneously cut, the challenging accurate alignment of the soft cloth is avoided, and the cutting fractures of all layers of materials can be uniformly and consistently aligned; the simple computerized quilting machine and the components such as the vibrating knife, the laser cutting, the metal curling barrel/the edge wrapping barrel/the overlock device and the like which have low cost, are mature and are easy to obtain are used, so that a large number of expensive electronic identification, positioning, contraposition, control and adjustment devices and the procedures of sizing, solidification, re-softening, dissolving and the like which have fussy and great limitations are avoided. Subsequently, the cut materials are fixed or do not move relatively (dislocated or deformed) by the conventional means such as a press frame, a press plate, an adsorption bearing platform and/or quilting, and then the sewing treatment can be carried out.

The edge sealing device comprising the curling barrel, the edge covering barrel, the overlock device and the like can be a conventional edge sealing device with invariable thickness, size and shape, and can also be an edge sealing device with adjustable thickness, size and/or shape, so that finished products with different thicknesses and edge sealing structures can be produced by the same equipment. For example, the same machine, if the thickness, size and/or shape of the edger is adjustable, may: when the gap of the edge banding device is small, the edge banding device is suitable for producing products with thin materials such as vests, undershirts, T-shirts and the like; when the gap of the edge banding device is adjusted to be slightly larger, the edge banding device is suitable for producing blanket, picnic mat with sponge interlayer, summer quilt, thinner sleeping bag, carpet, curtain and other products with thicker materials; when the gap of the edge sealing device is adjusted to be larger, the edge sealing device is suitable for producing products with thicker materials, such as thick sleeping bags, cold-proof cotton clothes, winter quilts and the like; the multifunctional device realizes multiple purposes.

Compared with expensive identification and control systems of companies such as Softnear Automation (Sewbots), Sewbo and the like, the invention only needs to utilize relatively simple and efficient mechanical means to straighten the fracture (such as a cloth brush in the following embodiment) and/or electronic means to identify the fracture (such as photographing identification), and the sewing system is followed by the cutting system, so that no obvious time or space for deformation or dislocation is left for each layer of material; the whole system has higher process integration level, simpler equipment, higher reliability and lower cost.

Manufacturers, represented by the electronic technology limited of setron, suzhou, setron and TPET (hereinafter referred to as "setron, suzhou or" TPET "), have developed a large number of fully automatic" four-sided seam "devices: firstly, cutting raw edges of the longitudinal left side and the longitudinal right side of a sewn material and sealing edges of the sewn material by using at least one group of cutting knives and at least one sewing machine fixed on the two sides of a machine frame on the longitudinal left side and the two sides along the conveying direction (longitudinal direction); after the edge sealing treatment of the left side and the right side is finished, the seamed material is cut off by a straight line cutting knife in the direction vertical to the conveying direction (transverse direction) of the seamed material; after the material to be sewn is completely transversely cut, the material to be sewn is conveyed to a second group of at least one sewing machine which is fixed on the frames on the front side and the rear side transversely along the conveying direction (transversely) of the material to be sewn so as to seal the front side and the rear side transversely of the material to be sewn, and four-side sewing is realized.

A manufacturer represented by Tianjin Fuyi group/Shang Gongyi Intelligent manufacturing (Tianjin) Limited company (hereinafter referred to as "Tianjin Fuyi" or "RICHPEACE") realizes edge sealing including edge sealing, curling and overlocking (also referred to as a "four-side machine", which is represented by the model RPSS-A04E-1/4,3,3-2528-C1- (J1,2+ K1,8, RPSS-AO4E-1/5,4,4-2525-S1-G1,2+ G2,2, RPCQ-ST-3,3-1992-2-L, S50, RPCQ-QC-1-2325-2-L, S50 and the like) by transversely moving or rotating the seamed material after longitudinal edge sealing on the basis of a continuously feeding gantry type quilting machine, and develops a nearly automatic quilt cover/production system on the basis (the equipment is cut transversely and then the quilt cover/overlock machine is cut, Two workers stand on two sides of a machine table for manual quilt cover turning before quilting, so the quilt does not belong to the full automation of zero manual intervention), Tianjin Fuyi is called as an 'inner seam quilt quadrilateral machine', and the model is RPSS-AO4E-0,4, 4-2428-C.

The manufacturers represented by Suzhou san an machinery manufacturing limited company (hereinafter referred to as "Suzhou san an" or "SANAN") simplify the system of Tianjin Fuyi, develop the automatic quilt cover/quilt (semi) production equipment with the model number ZDS300, and also eliminate the automatic overturning process with expensive equipment cost and manually realize the inside and outside bag overturning process. It is briefly described as follows: sewing the rectangular outer edge of the quilt cover together with the fabric, the lining and the filler by using a quilting machine, wherein only one edge is incompletely sealed, and a pocket is reserved for manual subsequent inward and outward turning; and cutting off the sewn rectangular outer edge transversely similarly to the four-edge seam to obtain a body primary product for subsequent manual inward and outward turning and sealing.

The advantages of the method and apparatus of the present invention are apparent over the prior art techniques described above, and are briefly summarized as follows:

compared with the four-side seam scheme of Suzhou Qiongpai TPET and other manufacturers: 1. after the existing four-edge sewing scheme is transversely or longitudinally cut, one group of generated sewing heads are natural downward hanging edges which are not fixed at all, the movement amplitude of the sewing heads is very large, and the positioning/alignment is difficult. Therefore, the four-side seam is mainly used for processing towels, sheets and the like, and can obtain a single-layer material with cutting lines at the other two sides as straight lines for alignment/positioning by tightening the two sides; when the free edge is aligned for double-layer or multi-layer materials, the alignment is difficult to realize, and particularly when the free edge is used for products with flocculent filling layers such as sleeping bags, quilts and the like, the free edge can not be aligned, and the flocculent filling layers with free edge notches are easy to scatter or fall off when being pulled, so that the effective production can not be carried out. Compared with the four-side seam scheme, the scheme of the invention can not only process a single-layer structure, but also can seal edges synchronously immediately after natural positioning/contraposition when the seam head is cut out, so that the flocculent filler is not required to be positioned/contraposition specially, and is sealed by the edge sealing mechanism immediately before being dispersed, and can not be dispersed; thus, there is no problem in handling double-layer, triple-layer or even multi-layer structures. 2. The existing four-side seam scheme can only be used for cutting rectangular outer edges in the transverse direction and the longitudinal direction to be used for manufacturing rectangular products such as towels, bath towels and bed sheets, and the like, but the scheme of the invention can be used for manufacturing any shape including rectangles through a cutting machine head and a sewing machine head controlled by a computer. 3. Although the four sides of the four-side seam can be zipped in an automatic mode, the four-side zipper under the scheme can only be a four-section zipper which is broken at the intersection point of the four sides (because the zipper arrangement mode under the scheme can only be that a longitudinal left zipper and a longitudinal right zipper are firstly arranged, after the two zippers and the body primary product are transversely cut, the two zippers transversely move and are arranged with a transverse front zipper and a transverse rear zipper, therefore, the four corners of a rectangle are necessarily cut), and the four sides cannot be continuously uncut (such as a fully-closed bag), the adjacent three sides cannot be continuously uncut (such as a sleeping bag envelope), and/or the adjacent two sides can be continuously uncut. The zipper of the invention can turn and turn freely along with the cutting machine head and the sewing machine head, thereby realizing the zipper layout structure which can not be made by the four-side seam.

Comparison with ZDS300 protocol of san ampere, suzhou: 1. the Suzhou san' an proposal also produces one group of seams which are completely free of fixed free edges after transverse or longitudinal cutting, so that the movement amplitude of the seams is very large, the seams are difficult to position/align, and the flocculent filling layers of the cut free edges are also easy to scatter or fall off when being pulled. The solution of the invention does not have these problems. 2. The Suzhou san' an scheme can only be used for cutting rectangular outer edges in the transverse direction and the longitudinal direction to be used for rectangular products such as envelope sleeping bags and the like, and can not be used for other non-rectangular products, and the scheme in the invention can be used for manufacturing any shapes including rectangles. 3. Because the zipper arrangement mode under the Suzhou san 'an scheme can only arrange two longitudinal left and right zippers and cannot arrange the zippers during transverse cutting, the Suzhou san' an scheme can only automatically arrange two parallel zippers at most on two opposite sides, so that continuous zippers on adjacent sides cannot be automatically arranged, and any two sides or variable continuous non-cutting zipper structures cannot be arranged. The layout structure of the zipper can be realized in the invention. 4. The Suzhou san' an scheme only saves the cutting and bag body sewing procedures in the quilt cover/quilt manufacturing process, the subsequent inside and outside turning and final sealing and the like still need to be done manually, the automation degree is not high enough, and large-scale and manual zero-intervention efficient production cannot be realized.

Compared to the Tianjin Fuyi RICHPEACE four-sided machine scheme: 1. the Tianjin Fuyi four-side machine can be used for manufacturing rectangular products and can not be used for manufacturing other non-rectangular products, but the invention can be used for manufacturing products with various shapes. 2. The Tianjin Fuyi four-side machine also breaks the four-side zipper at the intersection point of the four sides when the four sides are automatically zipped, and the zipper can be automatically sewed in a mode that the four sides, the three sides and/or the two sides are not sheared to the bottom according to the requirement. 3. The Tianjin is complex in equipment and high in equipment cost, and the process is relatively simple, the equipment integration level is high, and the cost is relatively low.

The zipper feeding is automatic zipper feeding, and if the zipper feeding mode of the product adopting the scheme is the traditional manual zipper feeding mode, all TPET four-side seams, Tianjin Fu Yi four-side machine and four sides of the product manufactured by Suzhou Sanan ZDS300 can obtain continuous and unbroken zipper structures; however, the sewing is manually supplemented in the later period, so that the efficiency is low, the labor cost is high, and the zero-intervention efficient production is not required to be realized.

For the purpose of utilizing the existing mature and stable technology and equipment as much as possible, we can also use various zipper arrangement devices as shown in fig. 28 to 34 on the existing inner seam quilt quadrilateral machine of the three-ampere ZDS300 and/or the Tianjin Fuyi RICHPEACE in Suzhou, namely, the technology and/or equipment of the invention can be realized in a simpler mode. Of course, in order to prevent the seam head from being dislocated, deformed or folded, etc., the fixing manner of the existing inner seam of the Suzhou san And ZDS300 and/or the Tianjin Fu RICHPEACE by the "outer clamping edge" on the quadrilateral machine may need to be additionally provided with an "inner clamping edge" fixing mechanism. These techniques are not difficult techniques and are not described in detail.

The edge sealing process of the edges of the primary body products such as sleeping bags is mainly explained, and how to sew or fix each layer of material on the body of the primary body product is not deeply explained. The sewing of the body primary product on the large body mainly takes the well-established and reliable computer quilting technology as the main technology. Of course, various common multi-layer material fixing techniques such as ultrasonic welding, even glue compounding/bonding, and the like can be adopted on the premise of not affecting other processes. In terms of the scheme of the computer quilting technology, the technical characteristics and the essence of the computer quilting technology are not essentially different, and the computer quilting technology falls into the protection scope of the invention as long as the quilting is firstly carried out and then cut, or the quilting is firstly carried out and then carried out, or the quilting is carried out and then carried out, or even the process sequences of the quilting is carried out and then cut, or the quilting is carried out and then carried out, or the process sequences of the quilting is carried out and then cut, and the. For example, if the sleeping bag does not interfere with the fixing mechanism, there is no substantial difference between the quilting of the inside of the body blank before and after the body blank is cut. In the suzhou san an ZDS300 scheme, if the body primary product is not required to be completely cut and then quilted, the lining and the filling layer are firstly quilted before cutting, and if the body primary product is not required to be completely cut and then quilted, the obtained quilt is a quilt with a loose-face structure (namely, the lining and the filling layer are not quilted together and can freely move). If the quilting of the lining and the filling layer is further simplified and omitted, the final product can be changed into a double-surface structure of the lining and the lining, the lining can not be formed by self-rolling in use, and the filling layer between the double surfaces is easy to tear, pile and the like, so that heat leak is generated. If the quilting is carried out after the bag turning, although the problem of double live faces can be solved, the subsequent quilting is carried out by manually turning the bag and then manually putting the bag into a quilting machine, and the improvement of the process and the efficiency is not obvious.

The method and the process of the invention can overcome the defects, and have the advantages of high production efficiency, zero manual intervention, low equipment cost and obvious progress.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention discloses a sleeping bag, clothing, a method and equipment for manufacturing the sleeping bag, the clothing, a bag and a cushion, wherein the sleeping bag with a zipper is manufactured by an automatic production line with high efficiency and low cost, so that the mechanical, automatic, batch, continuous and uninterrupted low-cost flow line production of the sleeping bag is realized, and the problems of a large number of sewing workers and low production efficiency in the sleeping bag production are solved.

Example 1

A method and apparatus for making a sleeping bag:

as shown in figure 1, the fabric 5, the filling material 6 and the lining material 7 of the sleeping bag are overlapped together and sent to a sewing machine head 16 including a quilting machine for sewing, so that the three are integrated into a body initial product 11 of the sleeping bag.

Then, the three parts (the original body 11) are cut into a shape corresponding to the pre-designed shape. For example, the edges shown in fig. 2 and 3 are rectangular (although other edges such as mummy, oval, cola, and irregular shaped edges are possible, as long as computer precise control is achieved).

Then, as shown in fig. 1 and 2 (or fig. 3), the fracture at the edge of the body preform 11 is hemmed with the hemming cloth 2 by the hemming head 14. At the moment, the fracture surfaces of the fabric 5, the filling material 6 and the lining material 7 are all wrapped by the edge wrapping cloth 2 to form an edge wrapping structure; the edge covering structure is fixed by the sewing thread 1 and cannot be scattered. The zipper cloth 3 of the sleeping bag zipper is sewn at the edge covering structure, namely, the zipper cloth 3 of the zipper is also fixed between the edge covering cloth 2 and the sleeping bag fabric 5 by the sewing thread 1.

The cutting process and the edge covering process can be carried out synchronously, namely, the edge is covered while cutting, and the cutting machine head and the edge covering device are integrated or the edge covering device is closely connected with the cutting mechanism; the two steps can be carried out in steps, namely, the cutting machine head and the edge covering device are mutually independent on the same machine table, and the cutting step is firstly completed and then the edge covering step is carried out. The two techniques are not substantially different from each other, but the former has advantages in preventing the fracture from being loosened and disordered, improving the production efficiency, realizing the technique and reliability.

For ease of understanding, the sewing head 16 and the edger head 14 are shown in FIG. 1 as two separate sets of independent sewing devices. To further simplify the production process and the equipment, we can even provide the sewing head 16 and the edging head 14 shown in fig. 1 as one piece. That is, the sewing head 16 and the edge banding head 14 share a set of sewing head (as shown in fig. 20 to 24), which cooperates with the quilting base 18 to form the sewing head 16 when quilting the body rough product, and cooperates with the edge banding barrel to form the edge banding head 14 when taping the cut edge of the body rough product. Such an apparatus and process is more simplified.

Similarly, if the hemming barrel fitted to the sewing machine head is changed to a hemming barrel, the hemming device of the present embodiment can be converted to a hemming device of embodiment 6 described below (as shown in fig. 27 in particular). The principles and the effects of the two are not greatly different, namely, the edge covering barrel matched with the sewing machine head is changed into the edge curling barrel matched with the edge covering barrel, the realization difficulty is not high, and more existing accessories are available on the market.

Of course, the apparatus may also be provided as multiple heads in order to further increase production efficiency. Different machine heads synchronously operate to respectively undertake different technological processes such as quilting, edge covering, hemming and/or label embroidering and the like, so that compared with the step-by-step operation, a great amount of time can be saved, and the production efficiency is obviously improved (as shown in figure 18 or figure 19).

Taking an envelope-type sleeping bag as an example, as shown in fig. 2 or 3, the zippers 12 are provided on the left, right, and lower sides of a body preform 11 (i.e., a sewn body of the face fabric 5, the filling material 6, and the lining material 7 in fig. 1) which is rectangular after being spread (i.e., the zipper cloth 3 of the zippers 12 is sewn together between the welt fabric 2 and the face fabric 5 as shown in fig. 1); the upper side of the rectangle is not required to be provided with a zipper, but the edge banding machine head 14 is directly used for edge banding to obtain an edge banding structure 13 shown in the figure, and a human body inlet and outlet 15 of the sleeping bag is formed after the zipper 12 is zipped.

After the steps are completed, a complete envelope-type sleeping bag is manufactured.

In use, the rectangle is folded into two as shown by the large arrows on the left and right sides in fig. 1 and 2 (or fig. 3), and the zippers 12 (i.e. the zipper teeth 4) on the left and right sides are zipped, so that the conventional envelope-shaped sleeping bag shown in fig. 4 can be obtained.

(Note: for ease of understanding, product and equipment dimensions, material thicknesses, gap sizes, etc. in the drawings attached to this specification are not shown to scale, since microstructures such as the bordure structure of FIG. 1 would not be clearly visible at all in macroscopic views such as FIG. 2 or FIG. 3 if drawn to scale)

Finally, as shown in fig. 4: the fractures of the edges of the sleeping bag fabric 5, the filling material 6 and the lining material 7 are edge covering structures, and the fractures of the edges of the fabric 5, the filling material 6 and the lining material 7 are all wrapped by the edge covering structures; the zipper cloth 3 of the zipper 12 is sewn at the edge covering structure. The zipper can be a closed full-length zipper structure covering the whole length of the edge fracture, and can also be a non-fully-closed zipper structure covering only part of the length of the edge fracture. The zipper is generally assembled by using a stacking zipper, and when the length of the clamped zipper reaches a preset value, the stacking zipper is cut off by using an automatic cutting machine head; of course, the strip zippers can also be conveyed by a clamping conveying system (such as a manipulator) under computer control when budget permits.

Further, it is even possible to replace the stringer or slide fastener with a half-side slide fastener (i.e., only one piece of fastener cloth 3 and fastener teeth 4 are used instead of using a pair of fastener cloth 3 and fastener teeth 4 in cooperation with a conventional slide fastener): after the half zippers are clamped as shown in fig. 2, the zipper ends 12A and 12B on the left and right sides of the finished body are put into the same zipper slider, and the zippers on the left and right sides are pulled to the zipper midpoint 12C. Of course, if zipper 12 is cut at zipper midpoint 12C, the zippers on either side of zipper midpoint 12C can also be separated and separately clamped by automated equipment. The effect and function of the different zipper clamping modes are not obviously different from those of the common strip-packaged zipper or the stacking zipper, but the zipper clamping mode is more convenient to implement through automatic equipment.

Further, as shown in fig. 3, the half zipper at the center of the zipper is provided as a zipper ring 12D (that is, when the zipper is simultaneously clamped at the center of the zipper, the movement of the binding device and the zipper conveying device is stopped but the zipper conveying device continues to convey the half zipper for a short time, and then the binding device and the zipper conveying device continue to move along the edge of the fracture along a predetermined path to perform the binding and zipper clamping, so that a zipper ring 12D with both ends clamped in the binding is formed, and the zipper ring 12D itself is movable rather than being clamped and fixed like other parts). The zipper ring 12D can be used for hanging or penetrating fingers for carrying; more useful, the middle position of the zipper ring 12D can be cut to form two new zipper teeth broken ends, and one or a pair of zipper heads are arranged, so that the double-pull double-open zipper on the common sleeping bag can be realized.

The process diagram in this example is shown in fig. 15. Comparing it with the prior art process diagram in fig. 13 or fig. 14, it can be seen that the process is much simplified, the main process is replaced by an automated process, and the labor cost is much lower.

In addition, the manufacturing process of the sleeping bag does not need bag turning and/or cotton filling, the sleeping bag with the zipper can be manufactured by an automatic production line at high efficiency and low cost, the mechanical, automatic, batch, continuous and uninterrupted low-cost flow line production of the sleeping bag is realized, the problems that a large number of sewing workers are required in the production of the sleeping bag and the production efficiency is low are solved, and the sleeping bag has a good application prospect.

Example 2

The hemming in the above embodiment 1 is a single hemming structure. In order to prevent the edge of the edge covering cloth 2 from being scattered, the edge covering cloth may be manufactured to have a double edge covering structure as shown in fig. 5. The sleeping bag making apparatus can be obtained by modifying and adding quilting machines that are well established and reliable in the prior art, as shown in fig. 18 to 23.

As shown in fig. 5, the fabric 5, the filling material 6 (mainly the shaped cotton mainly comprising the glue-sprayed cotton) and the lining material 7 of the sleeping bag are sequentially overlapped and then fed into a quilting mechanism to carry out the quilting of the body primary product 11 (the quilting thread is not shown in the figure for avoiding the complexity) and/or the sewing of the spread-out shape edge of the sleeping bag.

Then, the edge fracture is cut and cut, and double wrapping is carried out. That is, the edge of the covering cloth 2 is firstly folded to form a covering cloth folded layer 2A as shown in fig. 5, and then the covering structure including the covering cloth folded layer 2A and the edge fracture of the primary body product are sewn and fixed through the sewing thread 1, so that the double-covering structure is obtained, and the double-covering structure has better stability and more attractive appearance.

The specific structure of the double-edged edging cylinder can be seen in the edging cylinder 17 in fig. 24 and 25.

Finally, processes such as thread trimming, quality inspection and/or packaging are carried out. The processes of trimming, quality inspection and/or packaging can be completely manually executed, and can also be realized by partial or whole automatic and intelligent processes under the premise of budget permission.

When the sleeping bag is used, the sleeping bag is folded in half as shown by large arrows at the left and right sides in fig. 5, and the zipper teeth 4 at the left and right sides are pulled and closed, so that the sleeping bag is a conventional sleeping bag.

Example 3

In the process of closing the zipper of the common sleeping bag, the fabric 5 or the lining 7 contacted with the zipper puller is easy to be clamped into the puller. The zipper head is used for occluding the lining and/or the fabric of the sleeping bag into the zipper head to be clamped, so that the zipper has no problems of being pulled up or unsmooth, and the like. To prevent such an adverse phenomenon, as shown in fig. 6, an anti-seizing strip 8 made of a relatively hard material or a thick material may be added between the zipper cloth 3 and the wrapping cloth 2 (or the lining 7) during the wrapping.

The anti-blocking strip 8 can be made of woven tape, cloth strip or even strip plastic sheet, as long as the material is relatively hard or thick so as not to be easily blocked into the zipper head.

The sleeping bag in this embodiment is folded in half as shown by the large arrows on the left and right sides in fig. 6, and the zipper teeth 4 on the left and right sides are pulled and closed, so that a sleeping bag with the anti-sticking strip 8 as shown in fig. 7 can be obtained.

According to different structures and materials of the specific sleeping bag, the anti-blocking strip can be arranged between the zipper teeth 4 and the edge covering cloth 2 as shown in fig. 7, between the zipper teeth 4 and the lining cloth 7, and between the zipper teeth 4 and the fabric 5.

Example 4

When the common sleeping bag is used, heat in the sleeping bag is easy to leak out through meshing gaps of the zipper teeth 4 which are easy to leak out and the zipper cloth 3 made of the thin woven tape. To prevent such adverse phenomena, as shown in fig. 8, the fracture edge of the filler is wrapped a little more (i.e. the fracture filler extension layer 9 shown in fig. 8 is also wrapped in the binding cloth 2) during binding, so as to form a thicker and more-drum binding.

When in use, the sleeping bag is folded in half as shown by the large arrows at the left and right sides in fig. 8, and the zipper teeth 4 at the left and right sides are pulled and closed, so that the sleeping bag with the wind-blocking strips shown in fig. 9 can be obtained: when the sleeping bag is used, the wind shielding strip covers the zipper teeth 4 and the zipper cloth 3, so that heat leakage (commonly called as wind leakage) at the zipper teeth 4 and the zipper cloth 3 is reduced or prevented (just like the structure is called as the wind shielding strip). By the edge wrapping structure shown in the above fig. 1 to 9 or the edge curling structure shown in the following fig. 10 to 12, the wind-shielding strip which can make the sleeping bag have better heat-insulating performance can be obtained as long as enough extending layer 9 of the filling material is wrapped and covered on the zipper teeth 4 and the zipper cloth 3.

Of course, the hem or rolled edge structure may be used to form a weather strip not only where there is a zipper, but also where there is no zipper, such as at the body access opening 15 of the sleeping bag pouch shown in fig. 2 or 3. When the edge-wrapping or edge-curling structure forms a weather strip at the human body entrance 15 of the sleeping bag, the phenomenon that outside cold air enters the inside of the sleeping bag through the human body entrance 15 (namely, the shoulders and the neck of a user lying down) can be avoided or reduced, and the function of collar enclosure is achieved.

The edge covering cloth 2 can be cotton cloth or flannelette with the same or similar skin touch feeling as the sleeping bag lining 7. Therefore, no matter the edge covering structure is used as a wind strip at the zipper or a collar at the human body entrance 15, the human body skin touch feeling is better, and the direct contact between the human body skin and the harder zipper teeth 3 and/or the fabric 5 with the waterproof coating at the human body entrance 15 can be obviously reduced or avoided. The use experience of consumers of the sleeping bag is better.

Thus, the sleeping bag of the present embodiment can be obtained at a lower cost by automation, and the quality can be made better.

Example 5

In the four embodiments, the sleeping bag is obtained through the edge covering structure, and in order to further save material cost and simplify production flow and production equipment, the edge covering structure can be not adopted, and a curling structure as shown in fig. 10, fig. 11 or fig. 12 can be adopted. We can just replace the hemming device in the above embodiments 1 to 4 with a hemming device (see fig. 26 to 27 and fig. 35 to 41). The hemming structure can save the material cost of the hemming cloth, and the production process and the machine equipment for direct hemming can be simplified. The sleeping bag manufacturing equipment can also be obtained by modifying and adding a quilting machine which is well established and reliable in the prior art.

Specifically, the method comprises the following steps:

first, as shown in fig. 10, 11 or 12, the fabric 5, the filling material 6 and the lining material 7 of the sleeping bag are sequentially overlapped and then fed into a quilting mechanism to perform quilting and sewing of the body primary product 11 (in order to avoid complication, a sewing machine head and quilting lines are not shown in the figure). Then, the sleeping bag is cut into a preset shape and size to obtain a part to be sewn at the fracture edge (namely, a 'sewing head'), and then the edge curling treatment is carried out at the sewing head. The hemming may include seaming the three layers of the extended filler layer 9 together (as shown in fig. 11 and 12), or may not include seaming the two layers of the seam at the edge of the cut of the face fabric 5 and the lining 7 directly (as shown in fig. 10, that is, a push rod or plate is provided on the hemmer to be inserted between the face fabric 5 and the lining 7, and the extended filler layer 9 is pushed toward the inner side of the body preform 11 and away from the seam and the curled portion of the face fabric 5 and the lining 7 before the face fabric 5 and the lining 7 are rolled up). The sewing thread 1 may be positioned so as not to pass through the filler extension 9 at all as shown in fig. 10, or may pass through or pass through the filler extension 9 or even the filler 6 itself as shown in fig. 11 or 12.

Fig. 10 shows the hemming structure including the filler extension 9, but the sewing thread 1 does not pass through the filler extension 9.

Fig. 11 and 12 show that the hemming structure includes the extended filler layer 9, and the sewing thread 1 also passes through the extended filler layer 9, so that the product is more beautiful, and the wind and/or jam preventing effect is better.

Finally, processes such as thread trimming, quality inspection and/or packaging are carried out.

The above procedures can be realized by partial or all automatic and intelligent processes.

When the sleeping bag is used, the sleeping bag is folded in half as shown by the large arrows on the left and right sides in fig. 10, 11, or 12, and the zipper teeth 4 on the left and right sides are pulled and closed, so that the sleeping bag is a single sleeping bag.

Example 6

As shown in fig. 12, various labels 10 including washing marks, trademarks and/or warning marks may be further sewn to the hem structure and the zipper cloth 3.

The tag 10 may be positioned below the fastener cloth 3 as shown on the left side of fig. 12, or may be positioned above the fastener cloth 3 as shown on the right side of fig. 12; and may be located at a proper position such as the human body doorway 15 or the foot without the zipper.

The process can be realized by partial or whole automatic and intelligent processes; the automatic positioning and label placing system can be used for automatically and intelligently sewing on the production line.

Example 7

FIG. 2 illustrates a method and/or apparatus for making a "sleeping bag stationary, edge banding head moving" in accordance with the present invention.

The edge banding head 14 moves along the edge of the sleeping bag body primary product 11 and engages with the fracture edge (sewing head) of the sleeping bag body primary product 11 to carry out edge banding procedures such as edge banding, edge curling or edge curling, and the like, so as to obtain an edge banding structure 13 or an edge curling structure, and meanwhile, the zipper 12 is also sewn to the edge banding structure 13 or the edge curling structure.

The sleeping bag manufactured by the method can be folded in half as shown by large arrows at the left and right sides in figure 2, and the zipper racks at the two sides are fixed together by the zipper puller, so that a conventional envelope-shaped sleeping bag can be obtained.

Example 8

FIG. 3 illustrates a method and/or apparatus for making a "sleeping bag with moving and stationary bag sealer heads" according to the present invention.

The edge banding machine head 14 is fixed, the sleeping bag body primary product 11 rotates on a bearing platform of the sleeping bag body primary product under the control of a program, the fracture edge (sewing head) of the sleeping bag body primary product 11 is fed into the edge banding machine head 14, edge wrapping, edge curling or edge binding and other edge banding processes are carried out, an edge wrapping structure 13, an edge curling structure or an edge binding structure are obtained, and meanwhile, the zipper 12 is sewn to the edge wrapping structure 13, the edge curling structure or the edge binding structure.

The sleeping bag manufactured by the method can be folded in half as shown by large arrows at the left and right sides in figure 3, and the zipper strips at the two sides are fixed together by the zipper puller, so that a conventional envelope-shaped sleeping bag can be obtained.

Example 9

Fig. 16 shows a sleeping bag making apparatus of the present invention obtained by retrofitting an existing quilting machine:

the fabric 5, the filling material 6 and the lining material 7 are firstly overlapped together by a roller shaft 19 and conveyed into the equipment; the cutting machine head 20 synchronously cuts the fabric 5, the filling material 6 and the lining material 7 into a primary body product 11; then the sewing machine head 16 and the quilting base 18 are matched with each other to carry out quilting on the body primary product 11; the edge sealing machine head 14 and the edge sealing cylinder 17 are matched with each other to carry out edge sealing on the fracture of the edge of the primary body product 11, and simultaneously, various accessory components including a zipper, an anti-blocking strip, a wind shielding strip and/or various labels are stitched between the primary body product 11 and edge sealing cloth; then, a product inspection device 21 (such as a needle inspection machine, a defect shooting + marking machine, a line cutting machine, a blowing machine and the like) performs quality control and inspection on the product; finally, the finished body 23 is discharged by a folding and packaging device 22 (for example, a shirt folding packaging machine, which is already widely used on the market, is converted into a quilt cover or a quilt folding machine, or is additionally provided with a roll cover, a plug bag, a packaging machine and the like).

After the surface fabric 5 and/or the lining material 7 are unreeled and before the material is subjected to substantial processing, a cloth inspecting mechanism can be additionally arranged. Once the defects of the cloth are detected, proper marking, skipping, repairing or even stopping and changing the material can be carried out under the control of a computer, so that the problem that the subsequent processing procedures continue to process the defects, the material loss of other materials is caused or unqualified products are produced is avoided.

Of course, in this embodiment, other mechanisms such as automatic feeding, multi-layer material compounding, cloth splicing or slitting, pattern recognition high-speed shooting instrument, printing, label ironing, embroidering, quilting and embroidering, cotton loosening, cotton carding, thread end blowing or absorbing device, code spraying, marking, counting, rolling, automatic packaging and/or automatic storage and transportation can be added, and all the above processes can be synchronously performed under the accurate control of a computer to further improve the automation degree, reduce the manual work or manpower participation, and even realize a 'black light factory' without human intervention except for feeding and unloading.

For convenience of understanding, the cutting head 20, the sewing head 16 and the banding head 14 in this embodiment are independent from each other; however, in actual production, any two or even three of the cutting head 20, the sewing head 16 and the edge banding head 14 may be integrated into a set of device to improve production efficiency, reduce equipment cost and/or improve machine reliability.

The process diagram in this example is shown in fig. 15. Comparing it with the prior art process diagram in fig. 13 or fig. 14, it can be seen that the process is much simplified, the main process is replaced by an automated process, and the labor cost is much lower. In addition, the manufacturing process of the sleeping bag does not need bag turning and/or cotton filling, the sleeping bag with the zipper can be manufactured by an automatic production line at high efficiency and low cost, the mechanical, automatic, batch, continuous and uninterrupted low-cost flow line production of the sleeping bag is realized, the problems that a large number of sewing workers are required in the production of the sleeping bag and the production efficiency is low are solved, and the application prospect is good.

Example 10

The above embodiment 9 is realized by modifying the existing computerized quilting machine. The operating plane of existing quilting machines is generally horizontal as shown in fig. 16. The operation plane of the automatic sleeping bag production apparatus of the invention does not necessarily have to be a horizontal plane as shown in fig. 16, but may be a compact space-folding structure as shown in fig. 17. Therefore, the occupied area of the machine equipment can be reduced, and the renting cost of a factory and the like can be saved.

Example 11

Fig. 18 shows a sleeping bag making apparatus of the present invention, which is adapted from a quilting machine, and has a platform 28 and functional devices in which the cutting head 20, sewing head 16 and edge banding head 14 are separated from each other. The cutting head 20, sewing head 16 and edge banding head 14 perform the cutting, quilting and hemming tasks, respectively. When two or three of any functional devices cannot influence each other, all functional tasks can be executed simultaneously or synchronously; if any interaction is desired, one or both of the functional devices affected therein may be retracted via the guide rails 26 to one or both ends of the main frame 27, freeing up space above the platform 28 for the functional device to perform a task.

Under the precise control of a computer, the cutting machine head 20, the sewing machine head 16 and the edge sealing machine head 14 are respectively suspended below the machine head mounting frame 24 through the suspension rods 41, and can respectively move up and down and rotate through the suspension rods 41, move back and forth along the extension direction of the machine head mounting frame 24 through the positioning belts 25, and move left and right along the main frame 27 through the machine head mounting frame 24, so that each machine head can move to any area of the whole bearing platform without dead angles to carry out any stitch processing operation including straight lines, oblique lines, broken lines, turning and the like.

In order to avoid the head mount 24, the suspension rod 41, and/or the head or the like from contacting, colliding with, or interfering with other components or the material being processed, the head mount 24 and/or the suspension rod 41 or the like may be provided in a tiltable or bendable structure, and even the head mount 24 and/or the suspension rod 41 may be replaced with a multi-axis robot.

The zipper 12 is delivered to the sealer head 14 through a stopper hole 31 provided on the head mount 24 or the beam column. The edge sealing machine head 14 can be respectively or simultaneously a hemming device, a serging device (a serging device), a serging device and the like, and sews the zipper 12 to the edge sealing position while sealing the edge, so as to synchronously finish edge sealing and zipper feeding.

The platform 28 is provided with a plurality of air holes 29. When the materials on the bearing platform 28 need to be fixed, the air holes 29 can suck air to the inner side of the bearing platform to generate negative pressure, and the materials covered on the air holes 29 can be adsorbed on the bearing platform 28 to achieve the purposes of fixing the materials, positioning and the like. When the material on the bearing platform 28 needs to move (for example, the material on the bearing platform 28 is too heavy to affect the material conveying, or the material movement, the rotation speed or the degree of freedom is needed to be larger), the air holes 29 can blow air to the outer side of the bearing platform, and the material covered on the air holes 29 can be blown away from the bearing platform to a certain extent, so that the purposes of lifting the material, reducing the material conveying resistance and/or adjusting the material direction and the like are achieved. In addition, various rollers can be provided on the platform 28, and the rollers can roll in coordination in different modes under the control of a computer to enable the materials on the rollers to move in a preset direction.

The legs of the platform 28 may be telescoping legs 30. The height and/or inclination of the telescopic support 30 are/is adjusted according to the thickness of the processed material, the semi-finished product and the finished product, and the processing thickness and the processing range of the equipment are larger and wider by matching with the up-down, left-right, front-back, inclined movement, rotation and the like of the machine head. Even where the platform 28 is not required for machining, the entire platform 28 can be removed by minimizing the height of the telescopic legs 30, converting these devices into platform-less devices.

Example 12

FIG. 19 shows a sleeping bag making apparatus of the present invention in which the sewing head 16 and the edging head 14 are provided integrally. The sewing head 16 and the edge banding head 14 may be operated simultaneously or separately as required by the particular process. This has the advantage that the material input and volume of the device can be reduced.

Example 13

FIG. 20 shows a sleeping bag, sack, garment, mattress, or blanket making apparatus of the present invention in which the cutting head 20, sewing head 16, and edge banding head 14 are all integrally provided. The cutting head 20, sewing head 16 and edger head 14 may be operated simultaneously or separately as required for the particular process. This has the advantage that the equipment material investment, the equipment volume and the like can be further reduced.

Example 14

FIG. 21 shows an apparatus for making a sleeping bag, garment, bag or rug without a pillow block, but with the cutting head 20, sewing head 16 and edging head 14 all configured as an integral head.

Under the precise control of a computer, the integrated machine head can move back and forth along the extending direction of the machine head mounting frame 24 through the positioning belt 25, move left and right along the extending direction of the main frame 27 through the machine head mounting frame 24, tilt and move up and down through the suspension rod 41, or simultaneously move circularly by taking the suspension rod 41 as a rotating shaft, so that the forward, backward, tilt, reversing, turning, curving and the like of the machine head or each functional device are realized. In this way, the functional devices integrated in the integrated head can cover the entire spatial area for processing the product without dead corners.

In order to accommodate functional devices such as quilting that require a base support, a quilting bed 18 may also be provided in the lower portion of the apparatus as shown in fig. 21. The quilting base 18 can be fixed to the bottom head mount or can be free to move independently of the head mount.

FIG. 22 shows the apparatus of FIG. 21 in the manufacture of a sleeping bag: the fabric 5, the filling material 6 and the lining material 7 are simultaneously fed into the sleeping bag manufacturing equipment; firstly, quilting the body primary product 11 by a sewing machine head 16 in an integrated machine head (in order to avoid the picture of the attached drawing of the specification being too complex, the quilting stitch on the body primary product 11 is not shown in fig. 22); then the fixing frame 48 is pressed/covered on the quilted body primary product 11 under the control of the control rotating shaft 49, the fixing frame 48 above the body primary product 11 is matched with the fixing frame below the body primary product 11 to fix the body primary product 11 properly or make an integral motion after being fixed, so as to avoid or reduce the overlarge deformation or displacement of the body primary product 11 and an edge fracture (seam head) thereof in the edge sealing process (if a bearing platform is arranged at the lower side of the body primary product 11, the bearing platform can be matched with the fixing frame or the fixing plate above the body primary product to realize the fixing or synchronous motion); then the cutting machine head 20 in the integrated machine head cuts out the shape of the body primary product 11 according to the shape preset in the computer; the edge covering tube 17 (or curling tube, or overlock) and the sewing needle (the sewing needle in the sewing head 16 can be simultaneously used) in the edge sealing head which is also arranged in the integrated head are closely arranged behind the cutting head 20, and the cut fracture is immediately sealed. The zipper 12 is synchronously conveyed to the edge binding barrel 17, the edge curling barrel and/or the hemmer of the edge binding machine head 14 through a limiting hole 31 arranged at the machine head mounting rack 24 or the beam frame and the like under the control of a computer and/or a machine, and the zipper 12 is sewed at the edge binding position while the edge is bound; and synchronously zipping the edges while sealing the edges to obtain a finished body product 23.

The fixing frame 48 may be in various regular shapes such as a long strip shape, a rectangular shape (as shown in fig. 21 and 22), a ring shape, a hole shape, a circular shape, an oval shape, a vest shape (as shown in fig. 42), a waistcoat shape, an underwear shape, a one-piece cotton-padded clothes shape and the like, or in various irregular shapes which are completely the same as the shape of a finished body to be manufactured. However, the holding frame 48 should be sized just one turn smaller than the finished body 23, leaving a cut edge (i.e., "seam") of about 3 mm to several cm wide for edge sealing to form edge sealing structures including hems, and overlocks.

The fixing frame 48 is not limited to the operation of clamping and moving only by the upper and lower sets distributed on the outer side of the sewn product as shown in fig. 21 and 22, and may be partially positioned inside the body preform (as shown by the fixing frame 48B in fig. 38) and partially positioned outside the body preform (as shown by the fixing frame 48 in fig. 38) as shown in fig. 38, and the inner and outer sets cooperate with each other to perform clamping or moving more effectively. The clamping force of the clamping between the upper and lower sides of the material layer or between the inner and outer sides of the material layer may be derived from mechanical pressing as shown in fig. 21, 22, 36, 37, or may be derived from magnetic force or electromagnetic attraction that can penetrate the material layer to be clamped.

The curling barrel, the edge covering barrel, the overlock and/or the flat seaming device and the like of the machine head part are arranged into a detachable and interchangeable structure so as to adapt to different processing technologies and product requirements as much as possible.

Turning now to further details of the above manufacturing process, FIG. 24 is an enlarged view of one of the heads of FIG. 22 using the taping cylinder 17: the blade 38 (which may be a laser beam for cutting) mounted on the cutting head 20 cuts the body preform 11, and the edge covering cylinder 17 immediately follows the blade 38 to cover the cut edge. The zipper 12 (i.e. the zipper cloth 3+ the zipper teeth 4 in the figure) and the edge covering cloth 2 are synchronously conveyed to the edge covering cylinder 17, and the zipper cloth 3 is sewn to the edge covering part while the edge is covered, so that edge covering and edge zipper are realized.

To ensure the edge sealing effect, a cloth arranging brush 50 can be arranged behind the blade 38 and in front of the edge covering cylinder 17. The brush 50 can rotate forward, backward, turn and/or withdraw; can be integrated with the machine head or can be an independent movement mechanism which can be separated from the machine head; a single cloth arranging brush can be set into a group, two or more cloth arranging brushes can also be set into a group, and multiple groups of cloth arranging brushes can be matched with each other, so that various different effects such as better flattening, curling and tightening are achieved. Fig. 24 shows two cloth-arranging brushes 50 provided after the blade 38 on the upper side of the body preform 11 and before the edge-covering cylinder 17, which form a set for sweeping the fracture edge (seam) of the cut body preform 11 to the left side, thereby preventing or reducing the folding, curling or displacement of the fracture of the body preform 11 after being cut. Preferably, two cloth arranging brushes 50 are also provided on the lower side of the body preform 11, behind the blade 38 and in front of the edge covering tube 17. Such a plaiting and alignment effect may be better. Of course, the cloth arranging device does not necessarily need to be a rolling brush, and can also be a blowing port, a scraping plate, a scraping blade and the like; the folding, curling and deformation can be avoided and other procedures are not affected, so long as the effects are achieved, and the folding, curling and deformation can be respectively or simultaneously adopted.

In addition, a needle passing hole 42 or a needle passing groove can be formed in the edge banding device limiting plate 56 of the edge banding structure such as the overlock device, the hemming tube 39, the hemming folded plate 51, the hemming tube 17 and the like shown in fig. 24 to 41, so that the sewing needle 40 can conveniently penetrate through the hemming tube or the hemming tube 17 and the like for sewing. Of course, the sewing needle 40 may be arranged behind the edge banding device limiting plate 56 and closely follow the edge banding device limiting plate 56, and the folded edge wrapping cloth 2 and the aligned zipper cloth 3 are immediately and simultaneously sewn to the fracture of the body preform 11, so as to obtain the edge wrapping structure with the zipper.

Fig. 25 is a schematic cross-sectional view of the portion of the wrapping tube 17 in fig. 24: the zipper cloth 3 of the zipper is synchronously limited in a zipper cloth clamping groove formed by the edge covering cylinder 17 and the zipper arrangement plate 43; the width of the zipper cloth clamping groove is enough for the zipper cloth to pass through, but the width of the clamping groove opening 46 is smaller than the thickness of the zipper teeth 4; therefore, as long as the zipper cloth is kept properly tightened to the left side as shown in fig. 25 (this can be achieved by the zipper introduction direction, for example, by letting the zipper be always introduced from the upper left oblique side of the head portion as shown in fig. 24), the entire zipper is always securely confined in the slot for quick passage, and the arrangement, positioning and alignment of the zipper cloth are achieved. The sewing needle 40 closely follows the edge covering tube or simultaneously pierces the lock rolled edge covering cloth 2, zipper cloth 3, face fabric 5, filling material 6 and lining material 7 through a needle passing hole 42 on the edge covering tube, the sewing thread 1 is led to the lower sides of the edge covering cloth 2, zipper cloth 3, face fabric 5, filling material 6 and lining material 7 from the upper sides of the edge covering cloth 2, zipper cloth 3, face fabric 5, filling material 6 and lining material 7 and the like and is converged with the sewing thread in the rotary shuttle at the lower sides of the edge covering cloth, the edge sealing and the zipper feeding can be synchronously realized.

The method and the equipment in the embodiment realize the simultaneous feeding, quilting, simultaneous cutting, synchronous edge covering and synchronous zipper feeding of the fabric 5, the filling material 6 and the lining material 7, and finally the finished product 23 of the sleeping bag body is taken out from the machine, so that the manual step-by-step processing which consumes time and labor, the transfer of semi-finished products and the like are avoided.

Furthermore, one or more hemming, hemming and/or hemming devices, etc. may be integrated into a single head to perform hemming, hemming and/or hemming operations while cutting and applying a zipper, etc. to avoid or reduce the stroke of the head, the travel of the head, and/or the repeated/reciprocating travel of the head for different operations on the same trajectory. For example: the opening of the edge covering tube 17 is rightward in fig. 22, and the right-side cut by the cutting device 20 forms the edge covering structure 13 with the slide fastener 12 through the edge covering tube 17 and the sewing needle thread; at the same time, a hemming tube (not shown for simplicity) with an opening facing to the left may be provided on the left side of the hemming tube 17, and the left side cut by the cutting device 20 is formed into a hemming structure by the hemming tube and another set of sewing needles. That is, if the right-opening hemming barrel 17 and the left-opening hemming barrel are installed at the same time in the nose portion of fig. 22 so that they are back-to-back and the opening is oriented exactly right-to-left, the left-side cutting opening cut by the cutting device 20 of fig. 22 can be hemmed and the right-side cutting opening can be hemmed at the same time. When needed (for example, when just two body primary products are cut as shown in fig. 22), edge wrapping and edge curling can be performed simultaneously, edge curling is performed on the body primary product on the left side, edge wrapping is performed on the body primary product on the right side simultaneously, and the computer performs simultaneous operation, simultaneous non-operation or only operation of the edge wrapping device and the edge curling device according to the pre-designed position data; and can be simultaneously provided with a zipper, a label and the like, thereby achieving multiple purposes and achieving multiple birds with one stone; repeated or low-efficiency labor such as repeated or repeated edge finding, alignment and the like can be avoided or reduced, and the production efficiency is improved.

Furthermore, the curved connecting portion on the left side of the hemming barrel 17 in fig. 24 and 25 may also be ground to a sharp edge and protrude forward, i.e., the blade 38 is fixed to the hemming barrel 17 without providing a cutting head 20 separately. If desired, the projecting sharp edge can be used to cut the corresponding material to be sewn directly in place of the blade 38, so that the cutting device 20 with its blade 38 can also be integrated into the covering cylinder 17.

The equipment in the embodiment can realize that the material enters and the finished product comes out, and is a great improvement on the sleeping bag production process and equipment.

Example 15

By way of contrast, fig. 26 shows a conventional crimping structure: the face fabric 5, the filling material 6 and the lining material 7 are rolled into the curling tube 39 together, and the sewing needle 40 sews the rolled curling structure in the curling tube 39 to ensure that the curling structure does not scatter. The sewing needle 40 can be sewn through the through-needle hole 42 of the curling tube 39 as shown in the figure, or the curled structure discharged from the end of the curling tube 39 can be sewn well to avoid the curled structure from scattering after the curling tube 39 is directly attached or closely followed by the sewing needle without the through-needle hole. This is a common technical solution and needs no further description.

In contrast to the known hemmed can shown in FIG. 26, FIG. 27 shows a zipper arrangement provided on a hemmed can 39 of the present invention. A zipper arrangement groove is formed on the inward-folded tongue piece of the conventional hembar 39 shown in fig. 26 by a zipper arrangement plate 43; the width of the zipper cloth clamping groove is enough for the zipper cloth to pass through, but the width of the clamping groove opening 46 is smaller than the thickness of the zipper teeth 4; therefore, as long as the zipper cloth is kept properly tensioned to the left side as shown in fig. 27, the whole zipper is always stably limited in the clamping groove and rapidly passes through the clamping groove, and the arrangement, the positioning and the alignment of the zipper cloth are realized. The sewing needle 40 is closely behind the hemming tube 39 or through the needle passing hole on the hemming tube to simultaneously pierce the zipper cloth 3, the face fabric 5, the filling material 6, the lining material 7 and the like which are aligned through the limiting structures, so as to realize synchronous edge covering and zipper mounting.

Example 16

Examples 14 and 15 are examples in which the fastener is disposed in the clip groove and the fastener element is disposed outside the clip groove, but the present invention may also have examples in which the fastener element is disposed in the clip groove and the fastener is disposed outside the clip groove.

As shown in fig. 29, a fastener groove type fastener setting device 45 is manufactured such that the size of a fastener groove opening 46 is smaller than the thickness of the fastener element 4 but larger than the thickness of the fastener tape 3 or the minimum thickness of the fastener tape 3 after being pressed. When the fastener element 4 of the slide fastener is inserted into the hook groove and the sewing process is started, the fastener element 4 cannot be pulled out to the right side through the hook groove opening 46 and the fastener cloth 3 can extend out of the hook groove opening 46 to the right side. Thus, when sewing the slide fastener, as shown in fig. 28, the fastener element 4 always moves only inside the neck, and the fastener cloth 3 extends below the sewing needle outside the neck, and is conveyed and threaded together with the sewn face material 5, the filling material 6, and the backing material 7. Therefore, if the fastener stringer 45 shown in fig. 28 and 29 is fixed to the presser foot 44 of the sewing mechanism by means including a clamp, a thread, a screw, a rivet, or even an electric welding so that the fastener cloth 3 protruding out of the pocket opening 46 is always positioned between the sewing needle 40 and the material to be sewn, the fastener cloth and the material to be sewn can be moved synchronously and sewn together at the same time.

Example 17

In the present invention, the slide fastener can be arranged not only on the outer side of the material to be sewn as shown in fig. 25, 27, 28 and 29 but also on the inner side of the material to be sewn; this can be important for the aesthetics of certain products.

As shown in FIG. 30, the fastener chain can be arranged inside the material to be sewn by the fastener chain arranger 45 sandwiched between the face fabric 5 and the back fabric 7 (as can be seen from comparing FIG. 28 and FIG. 30 or from comparing FIG. 29 and FIG. 31, the fastener chain arranger 45 is the same as that shown in FIG. 28/FIG. 29 and FIG. 30/FIG. 31, but the fastener chain arrangement is performed by changing the left and right directions). In this case, the zipper teeth 4 are located outside the seam of the sewing thread 1, and these edge seals are not visually pleasing due to the presence of the edge breaks of the face material 5, the filling material 6 and the backing material 7. Therefore, as shown in fig. 32, the fastener groove for arranging the slide fastener may be extended into the bag-like structure to be formed by the face fabric 5 and the back fabric 7 (see the perspective view in fig. 33) so that the fastener element 4 is positioned inside the seam trace to be formed by the sewing thread 1. Since the zipper laying device 45 always moves in front of the sewing needle 40 and does not interfere with or affect the movement of the sewing needle, the sewing of the bag body is not affected although the zipper laying device 45 is positioned inside the bag body formed by the sewing thread 1 and the fabric 5 and the lining 7; the zipper laying device 45 withdraws the space formed by the surface fabric 5 and the lining material 7 from the last seam opening position before the bag body is completely sewn. The thus-laid slide fastener is fixed by the sewing needle 40 and the sewing thread 1 immediately after the fixing, and then as shown in fig. 34, the slide fastener is wrapped inside the bag-like structure. The bag-shaped structure manufactured in the way is basically not different from the bag-shaped structure manufactured by the traditional manual sewing, and the cut or the thread end can not be seen at the folded zipper sewing position only by turning the bag-shaped structure inside and outside, so that the product is more attractive (at the moment, the cut which is difficult to see is turned into the bag body which can not be seen by eyes). Of course, if the bag-shaped structure is turned inside out, the relative positions of the front and back sides of the fabric 5 and the lining 7 and the filling material 6 must be designed in advance, otherwise, the front and back sides of the lining are not right, the filling material is exposed outside the bag-shaped structure, and other adverse phenomena occur after the inside and outside turning.

By the embodiment, the primary product of the sleeping bag body with the zipper automatically arranged on the inner side of the bag-shaped structure can be obtained, and the condition that the zipper is additionally arranged manually is avoided, so that the production process of the sleeping bag is more efficient, time-saving and labor-saving than the production process of the known sleeping bag; the subsequent bag turning and sealing procedures can be completely the same as the prior known full-manual, semi-automatic or full-automatic quilt cover turning procedures.

In order to reduce the investment of the 'inside-outside overturning equipment' which is expensive and has relatively low reliability, the embodiments of the non-overturning bag are obviously better in process, and the problem that the fracture edge of the embodiments is not attractive can be covered and solved by curling, edge covering, overlocking or edge stretching and the like.

In order to facilitate the insertion of the zipper distributor 45 between the fabric 5 and the lining 7, a suction nozzle can be arranged above the fracture edge of the fabric 5, the fracture edge (upper side seam) of the fabric 5 is properly sucked to be higher by a point, the suction nozzle is arranged below the fracture edge (lower side seam) of the lining 7, the fracture edge of the lining 7 is properly sucked to be lower by a point, so that a neutral position is formed between the fracture edges of the fabric 5 and the lining 7, and the zipper distributor 45 is conveniently inserted between the fracture edges of the fabric 5 and the lining 7.

For ease of understanding, the zipper spreaders 45 and the sewing needle 40 are shown in two sets, left and right, in FIG. 34. In fact, if the equipment cost is further saved, only one set of zipper applicator 45 and sewing needle 40 can be provided, and the complete zipper loading and sealing process can be realized by moving the zipper applicator 45 and sewing needle 40 from one

zipper end

12A or 12B shown in FIG. 2 or FIG. 3 to the other zipper end along the track of the zipper 12 shown in the figures. It is not a difficult technique for the zipper applicator 45 and the sewing needle 40 to be turned or reversed under computer control. The provision of the plural sets of the zipper laying device 45 and the sewing needle 40 is advantageous in that the production efficiency can be improved, but the equipment investment can be increased; the advantage of a single set of zipper applicator 45 and sewing needle 40 is that equipment investment can be reduced, but production efficiency is somewhat reduced; the optimal scheme is selected according to the product characteristics, the capacity requirement and the like.

Therefore, according to specific product and process requirements, the process and equipment can avoid the process of 'turning inside and outside' and can also keep the process of 'turning inside and outside'; this can be accomplished by replacing the zipper applicator 45 as appropriate or by replacing the position and orientation of the zipper applicator 45.

Example 18

The above embodiments have been described in terms of the method and apparatus of the present invention being used to produce products of double or multi-layer construction including plus and minus materials, but the method and apparatus of the present invention is not limited thereto and may also be applied to single layer construction (e.g., fully automated sewing of products such as mats, blankets and towels) to improve or replace these existing single layer construction automated sewing devices. In particular, the obvious advantage of the present invention is that the existing methods and apparatus can be modified or replaced by the machine apparatus without the need for additional separate blanking operations. For example:

the curl flap 51 shown in fig. 35 is first produced: the hemming folded plate 51 is composed of a hemming vertical plate 51A and a long hemming transverse plate 51B, the hemming vertical plate and the long hemming transverse plate can be bent from the same stainless steel, can be manufactured by welding two stainless steel sheets and then polishing, and can also be manufactured by other methods such as injection molding or glass fiber reinforced plastic molding. The hemming flap 51 can be fixed to a machine head or other control equipment through the mounting hole 51C, and can move relative to the cutting fracture edge of the body blank 11 under the control of the machine head or the control equipment as shown in the figure.

In processing the curling of the single-layer material, different rotation direction brush groups (two counter-clockwise rotation brush 50A and clockwise rotation brush 50B in fig. 35) are arranged in front of and at the side of the curling flap 51. The cloth arranging brush 50A rotating anticlockwise in front of the hemming folded plate 51 brushes and sweeps the cutting fracture of the primary body product 11 outwards (namely, the right side in the figure) so as to avoid the folding, twisting or excessive displacement of the cutting fracture and the like; the cloth-arranging brush 50B on the side of the hemming folded plate 51 rotates clockwise to sweep and press the cutting fracture of the body blank 11 to the upper side (i.e. the left side in the figure) of the hemming transverse plate 51B to prevent the cutting fracture from rebounding off the hemming transverse plate 51B; the raised riser 51A may be secured to the hemming head, trimmer head, and/or sewing head for synchronous movement. Once the hemming folded plate 51 and the edge of the cutting fracture of the primary body product 11 move relatively and the two groups of

cloth arranging brushes

50A and 50B rotate in respective directions, the edge of the cutting fracture of the primary body product 11 is swept and flattened onto the hemming transverse plate 51B under the action of the cloth arranging brush 50B; the sewing needle 40 is closely attached or attached to the hemming cross plate 51B, and then the cut edge (head) which is not yet released or rebounded and separated from the hemming cross plate 51B is immediately sewn and fixed, so that the required hemming structure 39 can be obtained (in fig. 35, the hemming structure 39 behind the sewing needle 40 is not intentionally drawn to be understood to be closed immediately, and in practical situations, once the hemming structure is pierced by the sewing needle 40 and sewn by the sewing threads 1 on the upper side and the lower side, the upper layer and the lower layer of materials are actually closely sewn together).

At this time, the primary body 11 may be fixed by fixing frames (not shown) at upper and lower sides thereof to further prevent or reduce deformation or displacement of the primary body 11.

Fig. 35 shows the state in which the curl flap 51 is operated in a perspective view, and fig. 36 shows the state in which the curl flap 51 is operated in a front sectional view.

The fixing frame, the cloth arranging brush 50 and the hemming folded plate 51 can be precisely matched with a machine head, a cutting and sewing device on the machine head and the like under the unified control of a computer, so that hemming sewing is realized.

If a zipper is desired, it is sufficient to attach a suitable zipper applicator to the hem flap 51, and need not be described in further detail.

Example 19

The hem flap 51 of example 18 can be used to handle not only single-layer body preforms but also two-or multi-layer body preforms. The curling effect of example 18 is also achieved by stacking two or more layers of the material of the body precursor together, as shown in fig. 37, and selecting sets of brush 50 (clockwise rotating brush 50B is shown, and counter-clockwise brush 50A is not shown) of appropriate size, direction of rotation and speed. That is, the present example is different from example 18 only in that a single layer material is replaced with a double layer material.

Example 20

The curling direction of the two-layer or multi-layer material in the embodiment 19 is single, and the two-layer or multi-layer material is not upward at the same time, but is downward at the same time, but in the actual production, the upper layer or the upper layers of the two-layer or multi-layer material need to be curled upward, and the lower layer or the lower layers need to be curled downward. In the present invention, this object can be achieved by providing the partition plate 52 between the two-layer material or the multi-layer material. As shown in fig. 38, a spacer 52 is provided between the first material layer 53 and the second material layer 54, such that the bristles of the cloth arranging brush 50 on the first material layer 53 are blocked by the spacer 52 to ensure that they do not contact the second material layer 54; the spacer 52 also keeps the bristles of the brush 50 below the second layer 54 from contacting the first layer 53. In this way, the upper and lower brush arrangements 50 are operated independently, respectively, to curl the upper first material layer 53 upward and curl the lower second material layer 54 downward without interfering with each other (fig. 38 shows the brush arrangement 50B rotated clockwise, and does not show the brush arrangement 50A rotated counterclockwise in front of it).

If a zipper is also desired, it is not necessary to describe here again as long as one or more suitable zipper appliers are attached to one or more of the hem flaps 51.

Of course, to facilitate the insertion of the partition 52 between the first material layer 53 and the second material layer 54, a suction nozzle may be disposed above the edge of the break of the first material layer 53, the first material layer 53 may be suitably sucked up a little, the suction nozzle may be disposed below the edge of the break of the second material layer 54, and the first material layer 53 may be suitably sucked down a little, so that a relatively large gap is formed between the first material layer 53 and the second material layer 54, and the partition 52 may be conveniently inserted.

Example 21

The zipper arrangement device in the above embodiment is a relatively small-sized component attached to the edge banding machine heads such as the hemming tube, the hemming folded plate, the hemming tube and the serger, and the sewed part of the zipper cloth is immediately pushed away from the edge banding machine head after the zipper cloth is fixed by the sewing thread.

If the size of the sewed object is larger or the process flow requires the support of the edge sealing machine head, the fixed size is larger or the shape of the product is more complicated, a hemming strip 47 as shown in fig. 39 to 41 can be adopted: the edge rolling strip 47 is inserted or wrapped into the edge rolling structure before edge sealing, and the zipper cloth 3 is also partially wrapped into the edge rolling structure; the sewing thread 1 does not pass through the hembar 47 and the hembar 47 may be provided in a smooth and flat strip, loop, ring, sheet or other suitable shape. After the hemming structure is completed by the sewing needle 40 and the sewing thread 1, the smooth and flat hemming strip 47 is drawn out. Since such edge strip 47 can be made of a material having excellent strength such as stainless steel, it is not difficult to implement.

If the label strip 47 is not pulled out, the obtained structure is the common core-spun edge at the seam of the outer surface of the luggage. The automation of the core-spun edge is lower in cost, higher in efficiency and more stable and reliable in quality than the manual operation of the core-spun edge in the known case.

In one-to-one correspondence with the single-layer unidirectional hemming structure in fig. 35 and fig. 36, the double-layer unidirectional hemming structure in fig. 37, and the double-layer bidirectional hemming structure in fig. 38, fig. 39 shows a single-layer unidirectional hemming structure in which an edging 47 can be extracted or cored, fig. 40 shows a double-layer unidirectional hemming structure in which an edging 47 can be extracted or cored, and fig. 41 shows a double-layer bidirectional hemming structure in which an edging 47 can be extracted or cored.

Example 22

Figures 43 and 44 show a vest made using the double layer double hemmed structure described in example 20 or example 21.

As shown in fig. 42, after the front and rear panels of the vest are mounted on the unwinding frame of the apparatus in the form of two rolls of uncut rolled cloth, the vest shown in fig. 43 and 44 is directly, rapidly and efficiently produced in a "manual zero intervention" manner. The first and second material layers 53, 54, which are provided on the left side of the head mount 24 in fig. 42, are uncut materials, rather than having been cut separately and machined as in conventional processes or in the case of the Sewbots, etc. The process and equipment are clearly better than the Sewbots et al.

With reference to fig. 42 and 43, first as described in embodiment 20 or embodiment 21, in order:

the first material layer 53 and the second material layer 54 are synchronously conveyed to the cutting head 20 by the roller shaft 19, after the photo of the input material is shot in real time by a high-speed shooting instrument (not shown in the figure) and the cutting layout preset in the computer system is compared in real time to confirm that the material is conveyed in place, the roller shaft 19 stops rotating, and the conveying of the cloth in the operation space is stopped (the cloth on the unreeling device can be continuously conveyed as the cache cloth in a mode of arranging a drooping bamboo curtain and the like, as long as the length of the subsequent cache cloth is just enough for the next action cycle).

Immediately after the cloth in the operating space is in place and stopped, the fixed frame or frames 48 controlled by the control shaft 49 securely hold the first and

second layers

53 and 54 of material, which are uncut and superimposed together, against deformation or displacement. As shown in fig. 42, these fixing frames 48 have been previously made in a shape corresponding to the vest, and sufficient and proper margin for sewing can be left at the edges of the fixing frames 48 after fixing for the passage of the heads including the cutting blade (or laser head) of the cutting head 20, the banding head 14 and the sewing device.

Then, the cutting blade (or laser head) of the cutting head 20 starts to operate, and the body preform 11 is cut in accordance with the preset vest shape and size. The edge part of the cut fracture of the cut body primary product which is not pressed by the fixing frame 48 is a seam head part which can swing up and down, a suction cup or an air suction head (not shown in the figure) following behind a cutting knife (or a laser head) sucks the cut first material layer 53 a little upwards and sucks the corresponding second material layer 54 a little downwards, and a small opening which can insert a partition plate 52 shown in figure 38 or figure 41 into the edge layer of the first material layer 53 and the edge layer of the second material layer 54 is obtained. After the partition plate 52 is in place, as shown in fig. 38 or 41, the groups of cloth-arranging brushes 50 are abutted against the seam near the partition plate 52, that is, the edge layer formed by the cutting gap of the first material layer 53 and the second material layer 54 and the outer edge of the fixing frame 48. Turning the hem 58 of the first material layer 53, the armholes 33 and the cut fracture edges of the neckline 32 upwards for hemming under the combined action of the cloth arranging brush 50, the hemming folded plate 51 and the sewing mechanism (the head size is too small compared with the whole machine size to be shown in proportion in fig. 42, but the hemming structure 34 of the front piece hem 58 turned towards the front/outer side of the vest in fig. 43 can be referred to); turning the edges of the hem 58, the armholes 33 and the cut off of the neckline 32 of the second material layer 54 downward for hemming (again, the head size is too small compared to the overall size to be shown to scale in fig. 42, but reference is also made to the hemming structure of the back hem of the vest in fig. 43, which is turned backward); the hemmed upper and lower layers of material are then hemmed on the left and right sides and the two shoulder portions to obtain a hemmed structure 57 as shown in fig. 43 (of course, the hemmed and/or hemmed portions can be performed on the two sides and the shoulder portions, except that the hemmed, hemmed and/or hemmed portions are performed on the two layers of material, namely the first material layer 53 and the second material layer 54, to sew the fracture (sewing) of the first material layer 53 and the second material layer 54 together, and the hemmed fracture edges of the hem 58, the armhole 33 and the collar 32 are performed on two independent hems, lockings and/or hemmed processes performed on only one of the first material layer 53 and the second material layer 54, wherein the first material layer 53 and the second material layer 54 are not sewn together so that the head of the consumer or the limb of the consumer can extend into and extend from the hole-like structure formed by the unsewn materials And so forth), an everted vest is obtained as shown in figure 43 (in figure 43 the front and rear panels are drawn in exploded view separated from each other for ease of understanding, in fact the front and rear panels are tightly sewn together by the overlock structure 57 formed by the sewing line 1 shown in the figure).

After turning the vest in fig. 43 inside out, the common vest shown in fig. 44 can be obtained: the hem 58, the neckline 32 and the armholes 33 of the front and the back pieces of the vest are all made into a hemming structure 34 so as to achieve the purposes of beautifying and preventing the edges of the cloth from being scattered, and the hemming structures 57 are arranged on the left and the right armpits and above the two shoulders; the stitches of the hemming structure 34 and the overlock structure 57 are turned inside the vest and are not exposed, so that the purpose of beauty is achieved.

In this embodiment, the first material layer 53 and the second material layer 54 are directly fed on the machine in a roll material manner without cutting, after optimized layout of a computer cutting system is performed on a plurality of or a plurality of vests (a part of the original body of a single vest can be inverted, inserted or even rotated on a layout plane, so as to reduce material waste during cutting), the vests are cut and edge-sealed one by an integrated machine head controlled by a computer, and the full-automatic production of the vest with the width of the whole width (about 1.5 m) and the width of the single product (about 0.5-0.8 m) is realized. However, how to alternately insert and discharge the waistcoats with the width of about 0.5-0.8 m with the maximum number on the cloth with the width of about 1.5 m in a mode of 'minimum material waste' is a very mature technology of the existing computer typesetting system and has no special difficulty.

Under the precise control of the computer and typesetting system, as shown in fig. 44, the trademark 55 can be made into the proper position of the vest body initial product by means of automatic silk-screen printing, pad printing, heat transfer, embroidery/embroidery, stitching, bonding, etc. before the inner and outer turning (even before cutting, as long as the computer typesetting determines the position of the trademark).

The fixing frame of the invention is generally a plane type upper and lower symmetrical structure, which respectively clamps the body primary product from the upper and lower directions (as shown in fig. 37); however, the fixing frame of the present invention is not limited to the planar upper and lower symmetrical structures. As shown in fig. 38, the fixing frame 48 can not only hold the original product from the upper and lower directions, but also be inserted into the sewed material at intervals to form a three-layer fixing structure (as shown by the fixing frame 48B in fig. 38), which is more effective in fixing and more beneficial to the operation of the manipulator. Of course, the frame 48B of FIG. 38 may be further provided in a double structure, the upper layer of which corresponds to the frame 48 of the upper layer outside the material to be sewn, and the lower layer of which corresponds to the frame 48 of the lower layer outside the material to be sewn.

The inner holder 48B can be used with either the divider 52 as shown in fig. 38 or the divider 52 of fig. 38 can be replaced with various applicators 45 such as those shown in fig. 28-33, i.e., the inner holder 48B can also be used with various applicators 45 to apply and sew together such as zippers, drawstrings, core bands, etc. into the hem seal of the upper and/or lower layers.

Further, the fixing frame 48 and/or the inner fixing frame 48B are not necessarily limited to a flat type. If necessary, the fixing frame 48 and/or the inner fixing frame 48B may be a concave-convex curved frame (or a concave-convex curved fixing plate or fixing block, so long as the operation of other equipment or material transportation is not affected, and the technical effect is the same when the curved frame structure is replaced by a curved plate-like structure or a curved block-like structure), as long as the fixing frame 48 and/or the inner fixing frame 48B having concave-convex curved surfaces can be mated with each other two by two to leave sufficient seams at the edges thereof. For example, the fixing frame can be set to be a concave-convex curved surface similar to the surface of the human trunk (a curved surface structure similar to three-dimensional cutting is made), and under the condition that the size and the shape of the sewing head are not influenced, the garment manufactured at one time can be more close to the skin and more attractive. That is, although the first material layer 53 and the second material layer 54 which are provided on the left side of the head mount 24 in fig. 42 are planar cloth without cutting, if the fixing frame 48 provided on the lower side or the right side of the head mount 24 in fig. 42 is not a planar structure but a curved structure which can be fitted to each other up and down, the planar cloth which is fed from the left side of the head mount 24 in fig. 42 can be naturally fixed as the curved cloth by the curved fixing frame; moreover, due to the tight fixation of the fixed frames, the concave-convex curved surfaces inside these fixed frames do not affect all the seam heads outside the fixed frame 48; the sewing heads can still be kept on a plane for the integrated machine head to carry out processing of each process. Of course, if the seam heads on the outer edge of the fixed frame 48 are not distributed on a plane but on a curved surface, the integrated machine head under the control of the computer can also process seam heads distributed in a curved or curved manner in a three-dimensional space as it is because the integrated mechanism can be lifted and lowered and tilted. Even if the budget allows, the multi-axis robot arm can be used to replace the head mounting frame 24, and the integrated head can be operated by the robot arm under the control of a computer, so that the three-dimensional sewing of the sewing head in any direction, any plane and/or curved surface in the processing space can be realized.

In addition, if the opening diameter of the collar 32 is too small to make the head not extend out, the cutting head 20 can cut a vertical cut (as a placket or a half placket) at the collar 32 to be used as the collar of the collar, and the placket zipper or the nylon fastener can be synchronously installed as described in the above embodiment. If the cuffs of other clothes are provided with openings too small to influence the situation that the four limbs enter and exit, the sleeve vent needs to be opened, and similar treatment can be carried out. For the sake of simplicity, this description and the accompanying drawings do not describe in detail what appears to be obvious and modifiable by those skilled in the art.

Underwear vests, gauze ball suits, advertisement vests and the like with huge demand can be quickly, efficiently and inexpensively manufactured by the method and the equipment. The method is particularly suitable for products such as gauze ball covers, advertisement waistcoats and the like which need to continuously adjust the quantity of stock and make quick response along with the competition process and the elimination of the competition teams.

The method and apparatus described in this embodiment are simpler, more reliable and less costly than SEWBO and others in the United states, which require that the material to be sewn be hardened first and that a large number of sensing, imaging, comparing, computing and/or controlling devices be provided. Of course, various appropriate sensors, photographing, comparing, calculating and/or controlling devices can be installed on the device described in this embodiment to achieve faster and better production effect, but because the first material layer 53 and the second material layer 54 in this embodiment are cut simultaneously, complicated and tedious processes of cutting, feeding, positioning and aligning can be avoided, the same product can be made with simpler device and lower cost, and the improvement is obvious.

Example 23

In addition to the sleeping bags or garments described in the above embodiments, the present invention may also be applied to the production of single layer products such as mattresses (e.g., picnic mats) and blankets (e.g., polar fleece blankets) that do not require zippers. That is, it is possible to implement on a quilting machine: after the raw material coiled material of the cushion or the blanket is arranged on the machine, the equipment of the invention directly finishes the procedures of cutting, edge covering, edge curling or overlocking, even cloth label applying, hand lifting/ear pulling/climbing and the like at one time without separate blanking and sewing and manual intervention, and the finished cushion or blanket to be packaged is discharged by the machine, thus having more competitive power on production efficiency and cost. Specifically, the method comprises the following steps:

as shown in fig. 55, after a single-layer raw material roll 61 of mat or blanket is processed, the process of cutting, edge covering, curling or overlocking, even labeling, lifting/pulling/climbing, etc. are all finished at one time by the device of the invention under the control of a computer in the form of 'manual zero intervention', and the finished mat or blanket to be packaged is discharged by the machine without additional blanking and sewing. Fig. 55 shows a case where a finished product is an overlock structure 57 by the execution head overlock 60 of the edge banding head 14. Only the execution head of the edge bonding machine head 14 shown in fig. 55 is replaced by the edge bonding cylinder 17, so that the edge bonding structure 13 can be manufactured by the equipment; the hemming structure 34 can be produced by the apparatus by simply replacing the actuating head of the hemming head 14 with the hemming barrel 39. It can be seen that the corresponding overlock structure 57, overlock structure 13 and/or hemming structure 34 can be obtained by replacing the execution head of the hemming head 14 with the overlock 60, overlock tube 17 and/or hemming tube 39.

FIG. 22 shows the apparatus of the present invention when it is used to treat three or more layers of material, such as sleeping bags and cold protective clothing; FIG. 42 shows the apparatus of the present invention in the context of processing a double layer of material such as a vest, vest or the like; figure 55 shows the apparatus of the invention when it is used to treat a single sheet of material such as a mat, blanket or the like.

Example 24

FIGS. 45 and 46 illustrate one-piece infant sleeping bag embodiments of the present invention.

The cutting fracture positions of the collar 32 and the armholes 33 are hemming structures 34, and the cutting fracture positions of other side edges and bottom edges are hemming structures 13 with zippers 12.

When the infant sleeping bag is unfolded as shown in fig. 45, the infant sleeping bag can be flatly and flatly spread on the ground, a table top, a bed surface or a plane such as a sofa and the like without folding so as to be used as a cushion or a quilt and the like; can also be used as a small blanket to wrap the infant. When zipper 12 is closed as shown in fig. 46, it is a conventional sleeping bag for infants.

The neckline 32 of the infant sleeping bag of FIG. 45, when folded as shown in FIG. 46, is a semi-circle having substantially the same front-to-back dimension and shape, which may not be well suited for a person's neck (because of the ease with which the neck may be tightened). Therefore, the neck opening 32 can be moved downward from the geometric center of the developed view as shown in fig. 45 by a proper distance to obtain an ergonomic neck opening with a low front and a high back; moreover, the neckline 32 shown in fig. 45 can be made into various left-right symmetrical but up-down asymmetrical shapes such as inverted water drop shape, pear shape and/or spindle shape, and the neckline which is 'low front and high back' and/or 'narrow front and wide back' and accords with ergonomics can be obtained after being folded; there are many implementations.

The infant sleeping bag can be produced on the equipment of the invention in a full-automatic and high-efficiency way, so the price is much better than that of the original infant sleeping bag which is basically sewn by hands; the anti-kicking sleeping bag is not only suitable for being purchased as an infant anti-kicking sleeping bag in a single family, but also suitable for being purchased in batches, at low cost and on a large scale as an afternoon nap sleeping bag in hospitals, kindergartens, schools and the like.

For more convenient use, a urine/peculiar smell detector, a physiological index sensor such as heart rate/body temperature, a recording/video/audio-video transmission device, a sleep/wake/cry monitor, a heating/cooling/constant temperature device, a zipper automatic opening or closing device (such as YKK AUTO CAMPING) and the like can be arranged on the infant sleeping bag. The devices can exchange information with terminals such as mobile phones like intelligent threading equipment, and achieve the purposes of enabling people such as parents, nurses, nursing staff, teachers, doctors and the like to remotely monitor or adjust in real time, accumulating various health and growth data indexes and the like.

Example 25

Fig. 47 and 48 show an embodiment of a one-piece cold-proof vest according to the invention.

The positions of the collar 32, the armholes 33 and the lower hem 58 are hemmed structures 34, and the side edges (armpits) of the waistcoat body 35 are a zipper 12 and a bound structure 13. When the cold-proof waistcoat is unfolded as shown in fig. 47, the cold-proof waistcoat can be flatly and flatly spread on the ground, a table top, a bed surface or a plane such as a sofa and the like without folding, and can be used as a cushion or a quilt and the like. When zipper 12 is closed, as shown in FIG. 48, it is a cold-proof vest to be worn under an outer garment.

The cold-proof vest can be produced on the equipment of the invention in a full-automatic and high-efficiency way, so the price is much better than that of the original vest basically sewed by hands.

Example 26

Fig. 49 and 50 show one-piece cold protective cotton wear embodiments of the present invention.

The positions of the collar 32, the cuffs 59 and the lower hem 58 of the cotton-padded clothes are of the edge-curling structure 34, and the two sides of the cotton-padded clothes body 36 and the sleeves 37 are both provided with the zipper 12 and the edge-curling structure 13. When the cold-proof cotton clothes are unfolded, as shown in fig. 49, the cold-proof cotton clothes can be flatly and flatly spread on the ground, a table top, a bed surface or a plane such as a sofa and the like without folding, and can be used as a cushion or a quilt and the like. When the zipper 12 is closed, as shown in fig. 50, it is a normal cold-proof cotton clothes.

The edge covering structure 13 at the outer side of each zipper 12 of the cotton-padded clothes can be made into the weather strip as described in the embodiment 4, and the collar 32, the cuffs 59 and the hems 58 can also be made into collar girdles or hems as described in the embodiment 4, so that the cold-proof effect can be better.

In the case of the tag 10 shown in fig. 49 and 50, the slide fastener 12 is conveyed and conveyed to the binding structure 13 at the same time when sewing, and the tag 10, the slide fastener 12 and the binding structure 13 are sewn at one time. The principles and arrangements of the arrangement of the label 10 and the zipper 12 are not very different, either: the arrangement of the labels 10 is intermittent, and the labels 10 with the preset size can be conveyed and clamped to the edge covering structure 13 only when the label arrangement device runs to the preset position; and the arrangement means of the slide fastener 12 is arranged to continuously (or successively in stages) arrange the slide fastener 12 to the prescribed respective positions. In the zipper distributor or the label distributor, when the position and the length of the distributed zippers or labels are suitable, the cutting device on the distributor can cut the zippers or the labels under the control of a computer, and the conveying is resumed under the control of the computer when the zipper distributor or the label distributor runs to the next preset position.

The cold-proof cotton-padded clothes can be produced on the equipment of the invention in a full-automatic and high-efficiency way, so the price is much better than that of the original cotton-padded clothes which is basically sewn by hands.

Example 27

The sleeping bag of embodiment 24 may also be formed in two pieces for ease of carrying and/or use. As shown in fig. 51 and 52, the original one-piece infant sleeping bag is broken at the shoulder and provided with a zipper 12 or a nylon fastener of a proper length. When the zipper is used after being made, the corresponding zippers 12 or nylon hasps on the two sheets are connected for use.

Each piece of the infant sleeping bag can be used as a seat cushion and a cover, and can be produced on the equipment of the invention in a full-automatic and high-efficiency manner, so that the price is cheaper than that of the original sleeping bag which is basically sewn by hands.

Example 28

The infant sleeping bags of examples 24 and 27 are of a bag-like configuration.

If the fabric is changed into a single layer, the collar 32 and/or the armholes 33 are completely or partially removed, the simple bag is formed.

The simple bags with adjustable volume can be obtained by arranging a plurality of groups of zippers for parallelly separating the space in the bags. The simple bag is particularly suitable for being used as an outer bag of a sleeping bag, and when the force of a consumer is large (such as young and strong men) and the sleeping bag can be rolled tightly when being stored, a bag storage mode with a small containing space can be selected, so that the bag is convenient to carry and store; when the force of a consumer is small (such as old, weak, sick and disabled or children) and the sleeping bag is fed in the storage process, a bag storage mode with a large containing space can be selected, so that the problem that the original bag of a sleeping bag manufacturer often causes the consumer to feel difficult to roll and pack the general pain point is solved (because the manufacturer saves materials and transportation cost, and the automatic sleeping bag rolling machine of the sleeping bag of the manufacturer can roll the rolled bag to a size far larger than the small size of the general consumer under the driving of a motor, so that the margin is generally small even if the manufacturer leaves a loose shrinkage margin).

The zipper, the shoulder strap and/or the handle can be arranged at the proper position of the bag structure in the same way as the cloth label and/or the zipper, so that the bag with the zipper, the shoulder strap and/or the handle can be manufactured. These pull tabs, straps and/or handles do not necessarily have to be laid along the cut-outs but, if necessary, directly on the inner body of the body preform or body finish.

The bag can be completely opened or closed, and is suitable for being used as a shopping bag and a mat; under the condition that the bag body is made of waterproof materials, the opened bag body can even be used as a canopy and the like. The multifunctional umbrella is multifunctional, and is particularly suitable for outdoor occasions, traveling occasions and the like.

Example 29

The cold-proof vest of example 25 may also be made in two pieces for ease of carrying and/or use. As shown in fig. 53 and 54, the original one-piece waistcoat is broken at the shoulder and a zipper 12 or a hook and loop fastener of an appropriate length is attached. When in use, the zippers or the nylon hasps of the two waistcoats are connected.

The zipper or the nylon hasp can be replaced by a male buckle, a female buckle, a pull rope, a pull belt, a pull piece and other conventional modes. For example, the pin and box can be attached in an automated fashion by an automated dotter at preprogrammed predetermined locations and intervals, etc. The automatic clamping of pull ropes or pull tabs and the like can be completely the same as the automatic clamping of labels in the equipment and the method. Of course, the buttoning head, the drawstring head, and/or the pull tab head, etc. may also replace, be incorporated with, or be integrated together into an integrated head, if necessary. Even a simple button can be used without a male button and a female button, and a group of button-mounting devices are not changed into button-hole-opening devices, which is a popular technology in the field of clothing and does not need to be described any more.

Each piece of the cold-proof waistcoat can be efficiently produced on the equipment of the invention in a full-automatic mode, so the price is much higher than that of the original basic manual sewing.

The two-piece or multi-piece structure can be more suitable for modularized and high-efficiency production, each matrix is respectively and automatically sewn out in large quantity to be used as an assembly, and a final finished product is obtained after two or more pieces are combined. All the sheets can be completely and independently disassembled, and are easy to clean, dry and replace. Especially, the sleeping bag is suitable for products such as infant sleeping bags or clothes which are easily polluted by saliva, urine or excrement discharged by infants, milk stain and the like.

The advantage of a two-piece or multi-piece construction is that it is possible to select two or more pieces that are the same size or shape, or two or more pieces that are different sizes from one another before and after the two or more pieces are combined (but the connection portions are integrally matched to ensure proper and aesthetically pleasing connection). For example, if the neckline 32 of the infant sleeping bag, waistcoat, vest, cotton suit, or the like is required to be formed with different heights or widths, the shape and size of the two or more pieces before and after the combination are selected to be different, so long as the zippers or the velcro tapes are secured to connect the pieces properly and beautifully.

Example 30

In some cases, a plurality of processes such as cutting, quilting, embroidering, edge wrapping, punching, etc. may be performed simultaneously, and thus, a plurality of sets of integrated heads and/or other functional devices described in the present invention may be provided on the same main frame. Figure 23 shows a sleeping bag making apparatus of the present invention, in which a gantry beam (inverted U-shaped structure) and a cantilever beam (or turning bar) are used in combination. Under the control of computer, the devices of different integrated machine heads and/or single-function machine heads at different positions and with different structures can simultaneously, synchronously or respectively play their functions, and can quickly and well make various complex sewing products such as sleeping bags, bags or clothes.

In order to reduce or avoid excessive displacement or deformation of the body preform 11 during quilting, hemming, serging and/or hemming processes, a rigid frame or form may be pressed over the body preform without affecting these processes, in addition to the suction fixing effect of the large number of air holes provided in the support platform in the above-described embodiments. Such a template or press frame is a well established and common method in template technology that has been popular (in order to avoid too complicated graphics, a rigid frame or fixed template is not shown in fig. 23).

In addition, the winter protection door curtain or the winter protection curtain hung on the door frame or the window in winter in northern China can also be manufactured by the method and the equipment. Because a cold-proof filling layer is required to be placed between the front fabric and the rear fabric, the traditional cold-proof door curtain or cold-proof curtain is required to be manually sealed; the method and the equipment of the invention can realize full-automatic sewing without any manual intervention in the middle. The material enters, and the curtain or the cold-proof door curtain comes out. Even if the zipper arrangement of the present invention is not used in such embodiments, it would be a considerable advance in the manufacture of such unzipped products.

The brush 50 of the present invention is not the only part that can be used with the folded plate 51, and other methods such as blowing and folding (i.e., blowing air in different directions instead of rotating the brush in different directions) or mechanical clamping and folding can be used with the folded plate 51, and the method should be selected according to the specific process, material, quality and environmental requirements.

The "body" of the present invention refers not only to the body of the finished products such as sleeping bags, clothing, bags, blankets and mattresses, but also to the semi-finished products constituting or composing these finished products. For example, one of the two-piece finished products in example 27 and example 29 above, or one of the complex structures such as a garment having a plurality of tiles, can also be considered as a "body". That is to say, the "body initial product" referred to in the invention includes not only "sleeping bag body initial product", "vest body initial product", "waistcoat body initial product", "blanket body initial product" but also "split sheet body initial product" or "component body initial product", etc., and the "body finished product" referred to in the invention includes not only "sleeping bag body finished product", "vest body finished product", "waistcoat body finished product", "blanket body finished product" but also "split sheet body finished product" and "component body finished product", etc.

When a sewing product with a plurality of split pieces is manufactured, different low-cost assembly lines can be set for different split pieces to respectively manufacture different split pieces; the finished products of different splicing pieces manufactured by different flow lines are converged on an assembly line by devices such as a mechanical arm, and the assembly line can also use various splicing methods and equipment shown in the embodiment of the invention, so that the method and the equipment can be used for sewing a sewing product with a complex structure of a plurality of splicing pieces in a way of 'putting in various materials at one side and putting out finished products at the other side' of a flow line with zero manual intervention.

In order to improve the production efficiency, the main frame can be extended or enlarged to ensure that the main frame has enough space for a plurality of groups of primary body products which are arranged horizontally, vertically or horizontally and vertically, the plurality of groups of primary body products are processed simultaneously, and the production efficiency can be improved by times. Not considering by the condition of seam material transit time, can process two body elementary article simultaneously on the same line just means that production efficiency is improved to being close original twice, can process three body elementary article simultaneously on the same line just means that production efficiency is improved to being close original triple, can process four body elementary articles simultaneously on the same line just means that production efficiency is improved to being close original quadruple, analogize so on. For products with smaller sizes, such as waistcoats, vests and the like, because a plurality of body primary products can be arranged on the main frame, the production efficiency of the products can be improved by tens of times or even dozens of times.

Of course, various sensors, cameras, comparison devices, calculation and/or control devices, etc. may also be mounted on these devices in order to further improve control accuracy, production efficiency, product quality, etc. These devices or components are common and mature technologies in the field of sewing equipment, including quilting machines, and are readily selected.

The term "at least" as used herein includes the same.
