Description

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

Technical Field

The present invention relates to sleeping bags, garments, and methods and apparatus for making such sleeping bags, garments, and sewn articles such as blankets and cushions, and more particularly to sleeping bags, and garments, and automated, batch, and low cost methods and apparatus for making such sleeping bags, and garments.

Background

How to realize full-automatic sewing of soft, deformable and wrinkled cloth is always an area of extensive research in the automation field but no obvious result is achieved.

The following technical solutions are proposed by an automated sewing company represented by Sewbo in the united states for the purpose of precise positioning and precise control: the cloth is sized and/or frozen to harden into plate structure with certain rigidity and hardness, and the soft and flexible and/or elastic cloth is changed into plate structure with certain rigidity and hardness similar to metal plate, plastic plate, etc. for easy computer recognition, control, alignment and sewing, and the cloth is softened, dissolved and removed after sewing. Such a solution is of course possible, but there are also limited slurries or liquids which are suitable for sizing, curing and then softening, dissolving/removing with the cloth without affecting the various dyeing/printing patterns of the cloth at all, but which are also fed separately and together to the machine. Companies, such as Softwear Automation, have proposed using high precision cameras and intelligent systems (Sewbots), but are very expensive to manufacture, and can only be used for products with simple structures, such as T-shirts, and can not be used for thick material products, such as filling layers.

The existing sleeping bags, clothes, bags or mats, especially the sewing products with zippers or VELCRO (VELCRO, also known as Velcro, VELCRO, burr, etc.), generally need to lay flat and stack the rolled raw materials into multiple layers and then cut down, and then stitch the different cut pieces together by manual sewing machine, which is labor-consuming and has poor reliability and consistency of manual operation.

For example, the existing sleeping bag manufacturing process is generally as shown in the process diagram of fig. 13 or 14: fig. 13 shows an early common procedure: firstly, respectively and repeatedly stretching the fabric and the lining on a long cutting bed (cloth stretching), and respectively cutting the multi-layer fabric and the lining according to the required shape (blanking); sewing the cut single-layer fabric and the cut lining into a bag-shaped structure with inner and outer inversions (at the moment, the outer surface of the sleeping bag is arranged in the bag-shaped structure, the inner surface of the sleeping bag is arranged outside the bag-shaped structure, the outer surface of the sleeping bag is arranged outside the bag-shaped structure through a subsequent bag-turning process, and the inner surface of the sleeping bag is arranged inside the bag-shaped structure through a part or all of suture edges when the bag-shaped structure is sewn (at the moment, the zipper is also sewn in the bag-shaped structure, and the sleeping bag is turned outside the bag through a subsequent bag-turning process); then the bag-shaped structure is turned inside out (also called as a bag turning); filling materials (various fillers for heat preservation including cotton, chemical fiber, down feather and the like) into the turned bag-shaped structure; quilting the fabric layer, the filling layer and the lining layer which are approximately and uniformly overlapped and flattened to fix the filler, so that the fabric layer, the filling layer and the lining layer are integrated to avoid larger displacement of the filling layer or loopholes of the filler in the use process, and the heat preservation effect of the sleeping bag is influenced; sealing the filled bag-shaped structure; and finally, performing the procedures of quality inspection, packaging and the like. With the development of the technology of shaping cotton such as collodion, a common procedure used in recent years is shown in fig. 14: firstly, respectively carrying out multilayer overlapping and pulling on the fabric, the lining and the filling layer on a long cutting bed or the ground, and respectively cutting the multilayer overlapping materials according to the required shape; the cut single-layer fabric and the cut lining are sewn into a bag-shaped structure with the inner surface and the outer surface reversed (at the moment, the outer surface of the sleeping bag is arranged in the bag-shaped structure, the inner surface of the sleeping bag is arranged outside the bag-shaped structure, the filling layer is arranged outside the bag-shaped structure, the outer surface of the sleeping bag is arranged outside the bag-shaped structure through a subsequent bag-turning process, the filling layer and the inner surface of the sleeping bag are arranged 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 seam edges when the bag-shaped structure is sewn (at the moment, the zipper is sewn inside the bag-shaped structure, and is turned outside the bag through the subsequent bag-turning process); then the bag-shaped structure is turned inside out ("bag turning"); quilting the fabric layer, the filling layer and the lining layer which are approximately and uniformly overlapped and flattened to fix the filler, so that the fabric layer, the filling layer and the lining layer are integrated to avoid larger displacement of the filling layer or loopholes of the filler in the use process, and the heat preservation effect of the sleeping bag is influenced; sealing the filled bag-shaped structure; and finally, performing the procedures of quality inspection, packaging and the like.

The existing sleeping bags are produced by a large amount of manpower (especially the current increasingly expensive sewing workers), and have the advantages of complex and tedious production process, multiple steps, low production efficiency and automation degree and high wage cost; and the zipper sewing and bag turning are indispensable and currently must be completed manually, so that the production efficiency is greatly influenced and the labor cost is increased.

The existing production process of the garment with the filling layer (the thermal insulation layer) is basically the same, and because the sleeves, the neckline, the pockets, the buttons and the like are needed to be arranged, the process is more complex, the working procedures are more, the consumed labor is more, and the production efficiency is lower.

In the existing production process of carpets, rugs or picnic mats, raw materials which are not cut are rolled and cut to obtain cut pieces, and then the cut openings of the cut pieces are covered with edges, curled edges or overlooked. Or a manual intervention production process is required.

Hemming cylinders (also known as hemming drums, hemmers, hemming dies, hemming heads, or hemming tools, etc.), hemming cylinders (also known as hemming Bian La cylinders, hemming devices, hemming dies, hemming heads, or hemming tools, etc.), and hemming devices (also known as hemming heads, etc.) have been used in the sewing industry in large numbers as non-patent or expired patent technologies, and both general sewing accessory shops and a large number of panned stores, etc. are sold; meanwhile, a plurality of hemming devices, hemming devices or overlocking device patent technologies matched with the flatcar can be used for reference and selection, for example, chinese patent application numbers 201810517529.9, 201810127043.4, 201610132359.3 and 201320581021.8. Such as those shown in chinese patent application nos. 201410348141.2, 201320017156.1, 201320517381.1, 201620167334.2, 201610738792.1, 201710910325.7. These proprietary or non-proprietary "hemming/taping/overlocking + zipper" techniques have been applied to flatcars, but the simultaneous application of "hemming/taping/overlocking + zipper" techniques to quilting heads has not been seen. Because, the conventional quilting machine uses the needle penetrating the body in the middle of the body as its design function, and does not consider other functions such as edge sealing and zipper feeding.

Therefore, under the circumstance of increasing labor cost, how to provide a method and equipment which is similar to an automatic computer quilting machine and can realize the process of feeding the head material and discharging the head finished product, wherein the middle production process is manual zero intervention, so that labor cost is reduced, production efficiency is improved, and products such as sleeping bags, clothing, blankets and/or cushions with filling layers and the like are mechanically and automatically produced, which is a problem to be solved by those skilled in the art.

Disclosure of Invention

In view of the above, the invention aims to at least solve the problems that a plurality of processes and a plurality of devices are needed to process sleeping bags, clothes, bags or mats, namely cloth is cut off firstly and then a sewing machine is operated manually to carry out splicing and sewing, so that labor and effort are wasted, and the reliability and consistency of manual operation are poor.

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

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

An object of the present invention is to provide a sewing process for sewing an article,

Step (1): spreading the sewn material which is not cut and cut on a sewing thread machine until the sewn material is at a position to be cut;

Step (2): after the sewn material at the position to be cut is fixed by the fixing mechanism, the sewn material is cut by the cutting machine head according to a preset shape, the root of the cut sewn head is fixed by the fixing mechanism in a mode that the two parts cannot move relatively so as to ensure accurate alignment and positioning of the sewn head (moreover, when necessary, the root of the fixed sewn head can move integrally along with the fixing mechanism so as to match the cutting machine head and/or the edge banding machine head and the like); and when or after the cutting machine head is used for cutting the sewn material into the preset shape of the body primary product which can comprise curves, the edge sealing machine head following the cutting machine head is used for synchronously edge sealing and sewing the sewn material to form the body finished product.

The beneficial effects of the invention are as follows: according to the sewing process, the sewn material and the sewing thread are simultaneously fed on a machine and spread to the position to be cut, and are simultaneously cut, and then the edge is sealed by the edge sealing machine head, and the sewing machine head is used for sewing.

The sewing process of the sewing product provided by the invention further comprises at least two layers of sewn materials of the lining and the fabric, and the two layers of sewn materials are overlapped and spread to a position to be cut.

The sewing process of the sewing product further comprises a zipper, a nylon fastener tape and/or a rope tape, wherein the zipper, the nylon fastener tape and/or the rope tape are arranged to the edge banding machine head through the arrangement mechanism and are positioned at the edge banding position of the cutting opening of the sewn material through the edge banding machine head to synchronously carry out edge banding and sewing, so that a body finished product is obtained. For example, a slide fastener necessary for a sleeping bag or a bag, a string (a drawstring) at a drawstring position of a drawstring bag, a core tape with a core curled, a slide fastener or a nylon fastener tape on a garment, or the like can be manufactured as such.

It should be noted that: the term "synchronous banding, sewing" or "sewn together" as used herein shall include not only the case where the fixation is sewn, such as by sewing a needle and thread through a zipper cloth or velcro of a zipper to fixedly sew them to a sealing position, but also the case where the drawstring of the drawstring bag is wrapped into the hemming structure of the mouth of the drawstring bag but is not sewn to the drawstring hemming structure by the sewing thread (if both are fixedly sewn, the drawstring cannot be pulled or pulled into the drawstring hemming structure, or the drawstring bag cannot be formed). Such cases are generally referred to in this specification as "synchronous banding, sewing" or "sewn together" descriptions.

The adoption of the method has the further beneficial effects that: the two layers of materials and the zipper, nylon button and/or rope can be sewn only through the integral edge sealing and sewing process, the zipper, nylon button and/or rope can be synchronously pulled, the bag body or the clothing body can be obtained through sewing the pulling of the zipper, the nylon button, the rope drawing of the zipper and/or the knitting belt, and the like, and the process of sewing the zipper, the nylon button and/or the rope to the body by one or more manual operation sewing machines is not needed 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 a filling material. Taking the making of sleeping bags as an example, the filling material is arranged between the fabric and the lining material and is simultaneously put on a machine, and the fabric and the lining material are synchronously cut into a preset shape by utilizing a cutting machine head.

The invention relates to a sewing process of a sewing product, which further comprises a wind shielding strip, an anti-blocking strip and/or a label, wherein the edge banding machine head synchronously positions the wind shielding strip, the anti-blocking strip and/or the label and zipper cloth, a nylon fastener tape, a rope belt and the like of a zipper at the cutting opening and synchronously banding and sewing.

The invention also provides processing equipment of the sewing product, which comprises a main frame, a machine head mounting frame, a controller, a cutting machine head, a banding machine head and a sewing machine head, wherein the cutting machine head is arranged on the machine head mounting frame and used for simultaneously cutting fabric and lining (taking a sleeping bag as an example), the banding machine head is used for synchronously positioning and banding a zipper or a nylon fastener with the fabric and the lining at a cutting opening, and the sewing machine head is used for sewing the zipper or the nylon fastener with the fabric and the lining at the cutting opening; the machine head mounting frame can be in the form of a mechanical arm, and if the mechanical arm is long enough, the mechanical arm can be fixedly mounted on or beside the main frame; the cutting machine head, the edge banding machine head and the sewing machine head slide and are rotatably arranged on the machine head mounting frame or the mechanical arm, and the controller controls the synchronous edge cutting edge banding sewing action of the cutting machine head, the edge banding machine head and the sewing machine head.

In the case where the sewn material has been fixed, the cutting process and the hemming/taping/serging process may be performed simultaneously, i.e., while cutting, hemming/taping/serging, the hemming/taping/serging mechanism immediately follows the cutting mechanism; or the two steps can be performed step by step, namely, firstly, the cutting step is finished, the cutting machine head is moved away, or the body primary products cut together are subjected to the hemming/taping/serging step by utilizing the cloth translation mechanism. The two are not very different in technology, and the former is not more advantageous in aspects of preventing fracture loosening and mess, technical realizability and reliability and the like.

The invention relates to a processing device for a sewing product, which 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 sequentially form 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 banding machine head and the sewing machine head are respectively and correspondingly connected to the lower end of a rotating rod to carry out the procedures of edge cutting, edge banding and sewing.

According to the processing equipment for the sewing product, disclosed by the invention, the main frame is further provided with the cloth bearing platform, and the cloth bearing platform is densely provided with the fine holes; and an air extracting or blowing device is arranged below the cloth bearing platform, and an air extracting opening or an air blowing opening on the cloth bearing platform is communicated with the fine holes.

The invention relates to a processing device for a sewing product, which is characterized in that the main frame is a computer quilting machine frame and comprises two guide rails and quilting bases which are arranged along the cloth direction, wherein the lower parts of the two ends of the machine head mounting frame are correspondingly and slidably connected with the guide rails; a roll shaft for conveying cloth is connected between the two guide rails; the quilting base is arranged at the position corresponding to the cutting machine head, the edge banding machine head and/or the sewing machine head.

The invention relates to a processing device for a sewing product, which is further provided with 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 and positionally connected on a machine head mounting frame through a mechanical arm and are used for carrying out edge cutting, edge sealing and sewing procedures on the fixed edge of the passing cloth.

The processing equipment for the sewing product provided by the invention further comprises more than two groups of three-head integrated machine heads, and the working procedures of edge cutting, edge sealing and sewing are respectively carried out.

The invention relates to a processing device for a sewing product, which is characterized in that the edge banding machine head is an edge banding machine head or a hemming machine head, the edge banding machine head is provided with an edge banding cylinder, the edge banding cylinder and the edge banding cylinder are provided with through holes which penetrate through the upper surface and the lower surface of the edge banding cylinder 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 be used for sewing immediately after the edge banding cylinder or the edge banding cylinder instead of arranging the through holes for the needle thread to pass through the edge banding cylinder or the edge banding cylinder, however, the latter has the limit and fixing effects on a sewn material due to the edge banding cylinder or the edge banding cylinder, and the sewing effect is better); or alternatively, the first and second heat exchangers may be,

The hemming machine head is provided with a hemming folded plate, the folded plate comprises a hemming transverse plate and a hemming vertical plate, and cloth arranging brushes are arranged at the front side of the hemming transverse plate along the cloth conveying direction and at the position of one side of the hemming.

According to the processing equipment for the sewing product, disclosed by the invention, the limit hole is formed in one side of the machine head mounting frame, the zipper, the nylon fastener tape and/or the rope belt and the like pass through the limit hole and are conveyed into the hemming cylinder or the hemming cylinder under the pushing or pulling action of teeth of the base of the sewing machine head, and the zipper, the nylon fastener tape and/or the rope belt and the like are sewn together with the lining material and the fabric through the through holes at the same time through a sewing needle on the sewing machine head.

According to the processing equipment for the sewn product, provided by the invention, the hemming cylinder and the side, close to the fabric or the lining, of the hemming cylinder are further provided with the zipper layout plate, and the interval between the zipper layout plate and the hemming cylinder and/or the bottom surface of the hemming cylinder is suitable for the penetration of zipper cloth of the zipper and is smaller than the zipper tooth height of the zipper.

The invention relates to processing equipment of a sewing product, which comprises a zipper layout device, wherein the zipper layout device is arranged at the front side of a hemming cylinder, a hemming cylinder and/or a serging machine head and comprises two horizontally arranged strip-shaped positioning plates, and the distance between the strip-shaped positioning plates is larger than the height of zipper teeth of a zipper; the strip-shaped locating plate is connected with one side of the strip-shaped locating plate along the length direction of the strip-shaped locating plate through a sealing plate, the other side of the strip-shaped locating plate is open and is contracted towards one side close to each other, the width of the contracted opening is used for enabling zipper cloth of the zipper to penetrate in and out and is smaller than the height of zipper teeth of the zipper, and zipper teeth of the zipper are located between the two strip-shaped locating plates.

The zipper layout plate or the zipper layout device utilizes the characteristic that the thicknesses of the zipper cloth and the zipper teeth are different, so that the zipper cloth can pass through the manufactured rigid clamping groove, clamping seam or bayonet and the like, and the zipper teeth cannot pass through the structure, thereby realizing the positioning of the conveyed zipper, and facilitating the accurate sewing of the subsequent sewing machine head. The above description is given 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 above layout plate or layout device is not limited to the layout of the zipper, and can be converted into a corresponding rope layout device, a strap layout device, a nylon fastener layout device, etc. as long as the rigid clamping groove, clamping slot, etc. matched with the zipper structure are replaced by the clamping groove, clamping slot, limiting hole, etc. matched with the cross section of the rope, strap, nylon fastener (i.e. the nylon fastener which is not cut into sections), etc.

According to the invention, the edge banding machine head and the sewing machine head are arranged on one frame and are arranged adjacently or integrally, namely, the hemming cylinder/the edge banding machine arranged at the sewing machine head is additionally provided with the zipper layout device, so that the synchronous and integrated sewing of the cloth hemming or edge banding or edge sewing and the zipper can be realized. The invention ensures that the zipper cloth is simultaneously rolled into the hemming cylinder or the cloth rolled by the hemming cylinder and then synchronously conveyed to the position between the sewing needle and the rotating shuttle for sewing. That is, when the cloth bending passage of the stainless steel or the hemming cylinder using the stainless steel as a main body is manufactured, the zipper passage is welded at the cloth bending passage, so that the zipper and the bent cloth are fed under the hemming/hemming sewing line together, and the hemming/hemming sewing line passes through the folded cloth and the zipper cloth of the zipper at the same time, thereby forming the hemming/hemming structure with the zipper.

The laying mechanism of the invention can not only lay and position the label, the zipper or the nylon fastener tape at the cutting opening of the sewn material, but also be provided with an automatic shearing device to shear the label, the zipper or the nylon fastener tape according to the preset length and/or position. In particular, the labels, which are rolled up in hundreds, thousands or even tens of thousands of labels produced by a printing plant or a label-weaving plant, are generally only of a length and width dimension of several centimeters to several tens of centimeters after being sewn to the finished product; the apparatus of the present invention thus produces a continuous plurality of labels intermittently fed to the banding head: when the edge banding machine head does not run to the position of the to-be-sewn label, the label cloth strip where the single label is positioned is connected to the label conveying device, but the conveying device is not operated, and the label cannot be conveyed into the edge banding machine head; however, once the edge banding machine head moves to the position where the labels are to be sewn, the label conveying device under the control of the computer immediately starts to move, and the label cloth strip where the single label is positioned is conveyed into the edge banding machine head, so that the edge banding machine head can sew the labels to the edge banding position together, and the purpose of loading the labels is achieved; and once one or a group of labels are conveyed according to the preset length and position of the computer, the label conveying device under the control of the computer immediately stops conveying the labels to enter a standby state, and a new conveying period is started repeatedly until the next edge banding machine head moves to the position where the labels are sewn again.

The processing equipment for the sewing product further comprises the presser foot, wherein the presser foot is arranged on the fabric in a lifting mode, is positioned on two sides of a cutter of the cutting machine head or on the rear side of a hemming cylinder of the hemming machine head, or on the rear side of a hemming cylinder of the hemming machine head or on two sides of a sewing needle of the sewing machine head.

The invention also provides a sleeping bag, a bag or clothing, 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 the nylon fastener connects the material of at least one layer into a cylindrical or bag-shaped structure for accommodating a human body or an object;

The sleeping bag, bag or garment body may be flattened flat, folded-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, emphasis is made on preventing others from misinterpreting the contents of the present specification in a literal manner in the manner of "drilling a bullnose", and therefore: in the present specification, the term "flattening without folding and wrinkles" means that the body product itself is free from folding and wrinkles after being flattened, and does not mean that the body product is free from folding or wrinkles, which are necessarily a little cloth. The latter is not practical because the hemming and hemming itself is achieved by folding and crimping the fabric followed by sewing. Folding and creasing of the fabric sewn to the upper portion of the finished body (e.g., hemmed fabric or hemming structure itself) is unavoidable and persists after sewing, even if the finished body is flattened. The folds and wrinkles of the partial cloth generated by the sewing process are not folds or wrinkles generated by the finished product of the body after being spread out, which are referred to in the specification or the claims.

The sleeping bag, the bag or the garment disclosed by the invention has the advantages that the sleeping bag, the bag or the garment is further characterized in that at least two layers of materials are stacked and cut at one time to obtain the body primary product, and the projection lines of the cutting ports of all layers of the body primary product can be simultaneously overlapped into the same projection line before being sewn; the zipper and/or the nylon fastener tape and the material of the at least one layer are simultaneously sewn together at one time through a banding structure comprising a banding, a hemming or a overlocking.

The sleeping bag, the bag or the garment at least comprises a layer of material and at least one connector comprising a zipper or a nylon fastener tape, wherein the connector connects the at least one layer of material into a cylindrical or bag-shaped structure for accommodating a human body or an object, and the sleeping bag, the bag or the garment can be flattened to a plane without folding or wrinkling before the connector is in a connected state or after the connector is completely opened. The material of at least one layer, especially the material of multi-layer superposition, is obtained by cutting at one time, and the projection lines of the cutting ports of each layer can be simultaneously overlapped 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.

It is emphasized that "flattened to a plane without folds and wrinkles" is intended to be adapted to be automatically manufactured in one pass on a plane or set of roll surfaces: the existing clothing, whether it is T-shirt, vest, underpants, short skirt, short sleeve, or the relatively complex structure of shirt, jacket, windcoat, suit, cotton-padded clothes, cotton-padded trousers, down coat, is made by front and back pieces or single piece folding sewing, and after being spread on a plane, always has folding place (that is, always has at least two layers of fabrics corresponding to the front and back of human body, and the two layers of fabrics are connected together by folding lines).

However, the finished garment of the invention is flattened to a plane without folding or wrinkling, which means that the connectors including zippers or velcro can be directly pressed onto the processing table (bearing platform) for automatic, efficient and disposable sewing processing as in the following embodiments of the invention; the steps of blanking (cutting), sewing sheets, sewing zippers and the like are not needed to be carried out respectively; but one end of the machine is fed, and the other end directly ejects the body finished product; no human intervention is required, except for the need to turn on and off the machine, and from time to time for maintenance and inspection.

In the existing production process of clothing or sleeping bags, cutting and sewing are needed to be performed separately. In particular, the structure of double or multi-layer is provided, each layer of cloth or filler is cut separately, and then the separately cut materials are manually overlapped to carry out processes such as zipper and sewing. The fabric, the lining and/or the filling material are integrally placed on the processing equipment, and the fabric, the lining and/or the filling material do not need to be cut in advance and respectively, but are simultaneously overlapped and cut at one time; and sewing is carried out simultaneously after the processing equipment cuts, so that independent blanking procedures are not provided, procedures of transporting and aligning cut pieces after blanking are reduced, and a large amount of manpower can be saved.

Moreover, the cut pieces in the existing clothing or sleeping bag production process are cut respectively, the cut openings are inevitably different in size and shape more or less, and the manual alignment is not completely consistent, but the cut pieces are fed into a sewing mechanism for sewing by being approximately aligned by experience, so that the phenomena of seam separation, seam lack and/or seam passing and the like are very easy to occur, and the product quality consistency is poor and even the sewing quality defect is caused. This is why a great deal of skilled sewing work is required. The multi-layer overlapped material is obtained by cutting at one time, and projection lines of cutting ports of all layers can be overlapped into the same projection line before being sewn; the alignment of the fracture can be ensured without an additional alignment process. Therefore, the sewing quality is better, the consistency is higher, and the efficiency is also higher.

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

It is another object of the present invention to provide a sleeping bag comprising a face material, a backing material, a zipper, and a hemming, hemming and/or serging structure; the multi-layer materials including the fabric and the lining are overlapped together and cut into a preset shape at the same time to obtain a body primary product; the edge wrapping, curling and/or serging structure wraps the cutting fracture of the edge of the primary product of the body; zipper cloth of a zipper is clamped between the edge covering, curling and/or serging structure and the body primary product, and the edge covering, the curling and/or the serging 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 the length of the edge break portion.

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

Further, the structure of borduring includes the last border layer that is located the surface fabric side, the lower border layer that is located the lining side and the tip border layer that is located the body primary product fracture tip, and the free end of last border layer and/or lower border layer is bent and is extended to tip border layer and corresponds and form last border bilayer structure and/or lower border bilayer structure, go up the integrative sewing of last border bilayer structure/last border layer, the zip fastener cloth of zip fastener and lower border bilayer structure/lower border layer three.

Further, the filler material extends to the end bag Bian Cengna and is integrally bent to the suture.

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

Further, the anti-jamming device further comprises a wind shielding strip, an anti-jamming strip and/or a label, wherein the wind shielding strip, the anti-jamming strip and/or the label are located 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 between the zipper and the lining layer.

When the sleeping bag is pulled with the zipper as the wind shielding strip, 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 is achieved. Of course, the weather strip formed by the hemming or hemming structure may be located not only at a place where a zipper is provided, but also at a place where there is no zipper, for example, at a body passageway, a clothing collar/cuff/armhole, etc. of a sleeping bag pouch-like structure. When the edge wrapping or curling structure forms a wind shielding strip at the human body entrance, external cold air can be prevented or reduced from entering the sleeping bag through the human body entrance (namely, the shoulders and the neck of a user lying down), and the effect of collar surrounding is achieved.

Preferably, the tipping cloth can be cotton cloth or flannelette which is the same as or better in contact with the lining of the sleeping bag; or, the lockstitch thread is cotton thread, knitting wool or knitting wool with better touch feeling contacted with human skin.

When the edge wrapping or hemming structure is used as an anti-blocking strip to pull the zipper, the common zipper head at the zipper position of the sleeping bag can be prevented from blocking the lining and/or the fabric of the sleeping bag in the zipper head, so that the problems that the zipper cannot be pulled up or the zipper is not smooth and the like are solved.

Of course, instead of the hemming or hemming structure serving as both the weather strip and/or the anti-seize strip, a separate weather strip and/or anti-seize strip may be additionally provided at the hemming or hemming structure and/or the slide fastener.

Wherein various labels, which may also include water wash labels, brands and/or warning labels, are sewn to the hem/over-lap/seam and/or zipper cloth.

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

Step1, feeding fabric, lining and filling material into a machine at the same time;

Step2, synchronously cutting the fabric, the lining and the filling material into a preset shape to obtain a body primary product, sewing according to the sleeping bag, and synchronously performing edge wrapping/curling/locking of a cutting opening and clamping a zipper to obtain a body finished product;

Finally, the post-treatment procedures of inspecting and packaging the body finished product are carried out.

More specifically: the equipment for manufacturing the sleeping bag is characterized in that fabric, lining and filling materials are simultaneously put on a machine and synchronously cut into a preset shape to obtain a body primary product, then the primary product is sewn according to the sleeping bag, and the edge wrapping/hemming/locking of a cut opening and the clamping of a zipper are synchronously carried out to obtain a body finished product. The sleeping bag manufacturing equipment is obtained by modifying and additionally installing a quilting machine which is mature and reliable in the prior art. Firstly, sequentially superposing a fabric layer, a filling layer and a lining layer of the sleeping bag, and then feeding the sleeping bag into a quilting mechanism for quilting the body primary product and/or sewing the edges of the spreading shape of the sleeping bag. Then, the edge break is cut to form a Seam (Margin to Seam), and then hemming/taping/serging is performed with respect to the wind throw.

Further, accessory structures including wind shielding strips, anti-seize strips and/or labels are also sewn together with the zipper cloth in a synchronous clamping manner.

The fabric layer, the filling layer and the lining layer of the sleeping bag can be synchronously quilted and/or cut after being overlapped in multiple layers, and the cotton filling process can be bypassed and the manual bag turning process which is necessary to date is avoided, so that the production efficiency can be greatly improved, and the manual work, especially the skilled sewing work, can be greatly reduced. Not only the quilting on the primary product of the sleeping bag body, but also the fixing and/or sewing of the edge fracture of the sleeping bag, even the hemming/taping/serging process can be completed by the same sewing mechanism or the same group of sewing mechanisms after being equipped with a proper hemmer/serger; the production efficiency can be greatly improved, and the production cost can be greatly reduced. Moreover, under the condition that the automatic control technology has been highly developed, the quality stability, the controllability and the consistency of the products produced by the machine under the accurate control of the computer are better.

The present invention combines the upper zipper and the hemming cylinder (or hemming cylinder) together into a unique method and apparatus for making a sleeping bag of the present invention that simultaneously or synchronously performs the upper zipper and the hemming (or both).

In the invention, the feeding, quilting, cutting, edge sealing, upper zipper and the like are integrated on a quilting machine, thus the invention belongs to an original breakthrough. Of course, it is also possible to finish the hemming, hemming or serging separately and then perform the zipper sewing, but this becomes a common "clear top zipper", and the production efficiency and the aesthetic degree of the final product are both affected.

Finally, processes such as slider assembling, thread trimming, quality inspection and/or packaging are performed. The processes of installing the pull heads, trimming the wire heads, inspecting the products and/or packaging the products and the like can be performed completely manually, or can be realized through partial or complete automatic and intelligent processes on the premise of budget permission.

Further, accessory structures including wind shielding strips, anti-seize strips and/or labels are also sewn synchronously with the zipper cloth.

Preferably, when the width of the filling layer, the fabric and/or the lining wrapped by the edge wrapping structure is relatively large, the relatively large strip-shaped edge wrapping structure formed by the edge wrapping structure can also directly serve as a wind shielding strip and/or an anti-jamming strip of the sleeping bag, and no wind shielding strip and/or anti-jamming strip is required to be specially arranged.

When the edge wrapping or hemming process is carried out, the manufacturing method or equipment of 'the sleeping bag is motionless and the edge banding machine head moves' can be adopted, and the manufacturing method or equipment of 'the sleeping bag is motionless and the edge banding machine head moves' can also be adopted. The sleeping bag bearing platform can be fixed, but the edge banding machine head with relatively small volume and weight bites the outer edge of the fracture of the sleeping bag in the predesigned shape to move, the technological process is relatively simple, and the equipment is relatively easy to obtain; the latter is not a problem under the condition that the prior bearing platform negative pressure air suction fixing technology or the blowing floating rotation technology is mature. The two should be considered comprehensively according to the specific requirements of products, process requirements, investment budget and the like, and then the most suitable mode is selected.

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

The disposable stitching can be single-needle stitching or double-needle or multi-needle stitching, and even one or more sewing threads can be added after the disposable stitching is finished to strengthen the stitching fastness, and the technical characteristics and the essence are not essentially different, and all the disposable stitching falls into the protection scope of the invention.

Of course, under the condition of budget allowance or processing technology requirement, the pattern/trademark making, printing, marking, scalding, screen printing, embroidery, quilting, cotton loosening, cotton carding, code spraying, marking, statistics, sleeve feeding, bag opening, button sewing, nail belt, folding, rolling, bag plugging, automatic packaging and/or automatic storage and transportation and other equipment or working procedures on the cloth inspection, fabric and/or lining can be matched with or/and matched with the previous or subsequent automatic process or equipment in the invention, so that higher degree and larger range of automation, flow and intellectualization can be realized.

Because the blanking program is integrated on the same machine, the machine can perform optimized typesetting (interleaving), optimization, blanking and the like at the same time only by combining with the traditional typesetting software, and the material waste is avoided or reduced 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 a cut-off opening is accurate to millimeter or sub-millimeter, otherwise, phenomena such as seam release, seam lack, seam passing, deformation, distortion and the like are extremely easy to occur once careless. This is why the technical solutions of the company Sewbo in the united states of america, etc. have been to apply a sizing and/or freezing to the cloth so that the cloth hardens into a plate-like structure with a certain stiffness and hardness. However, the proposal and equipment proposed by Sewbo company are very high in cost, and the liquid which can not bypass the blanking process, can be suitable for sizing, curing and then softening, dissolving/removing with cloth and does not affect various dyeing/printing patterns of cloth is limited.

The cutting process is integrated into one set of device at the same time, and two or more layers of materials are cut at the same time, so that the challenging precise alignment of soft cloth is avoided, and the cutting ports of the materials of all layers can be aligned and aligned uniformly; the simple computerized quilter, vibrating knife, laser cutting, metal hemming cylinder/serging machine and other low-cost and mature and easily obtained components are used, so that a large number of expensive electronic identification, positioning, alignment, control and adjustment devices and procedures of sizing, solidification, re-softening, dissolution and the like which are complicated in procedures and extremely limited are avoided. The cut materials can be fixed or not moved (misplaced or deformed) by conventional means such as pressing frames, pressing plates, adsorption bearing platforms and/or quilting, and the like, so that the sewing treatment can be performed.

The edge banding device comprising the hemming cylinder, the serging device and the like can be a conventional edge banding device with invariable thickness, size and shape, and can also be an edge banding device with adjustable thickness, size and/or shape, so that the edge banding device is beneficial to producing finished products with different thicknesses and different edge banding structures by using the same equipment. For example, if the thickness, size, and/or shape of the edge banding is adjustable, the same machine may: when the gap of the edge banding device is smaller, the edge banding device is suitable for producing products with thinner 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 products with slightly thicker materials such as blankets, picnic mats with sponge interlayers, summer quilts, thinner sleeping bags, carpets, curtains and the like; when the gap of the edge banding device is adjusted to be larger, the edge banding device is suitable for producing thicker products such as thick sleeping bags, cold-proof cotton clothes, winter quilts and the like; realizing multiple functions of one machine.

Compared with expensive identification and control systems of Softwear Automation (Sewbots), sewbo and other companies, the invention only needs to utilize relatively simple and efficient mechanical means to straighten the fracture (such as a cloth brush in the embodiment) and/or electronic means to identify the fracture (such as photographing identification), and the sewing system is closely attached to the cutting system, so that obvious deformation or misplacement time and space are not reserved for each layer of material; the process integration level of the whole system is higher, equipment is simplified, reliability is higher and cost is lower.

A number of fully automated "four-edge seam" devices were developed by manufacturers represented by the company "threo qiong pi" or "TPET" electronic technologies, inc: firstly, cutting burrs on the longitudinal left side and the longitudinal right side of a sewn material along the conveying direction (longitudinal direction) by at least one group of cutting knives on the two sides of a machine frame fixed on the longitudinal left side and the right side of the sewn material and at least one sewing machine on the two sides of the sewn material; cutting the sewn material by a straight line cutting knife in the direction (transverse direction) perpendicular to the conveying direction of the sewn material after the edge sealing treatment of the left and right sides is finished; after the transverse cutting is completed, the material to be sewn is conveyed to a second group of at least one sewing machine fixed on the frames at the front side and the rear side of the transverse machine along the conveying direction (transverse direction) of the material to be sewn, and the edges of the material to be sewn are sealed at the front side and the rear side of the transverse machine, so that four-edge sewing is realized.

Manufacturers represented by Tianjin Fuyi group/Shandong Fuyi Smart manufacturing (Tianjin) limited company (hereinafter referred to as "Tianjin Fuyi" or "RICHPEACE") realize edge sealing (also referred to as "quadrangle", which represents 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) comprising edge wrapping, edge curling and edge copying by a transverse movement or rotation mode on the basis of a continuous feeding gantry quilting machine, and develop a quilt cover/quilt production system (which is characterized in that two workers stand on two sides of a machine table for manually overturning the quilt cover after and before transversely cutting the quilt cover) on the basis of the continuous feeding gantry quilting machine, and the Tianjin Fuyi quilt cover is referred to as "inner seam quilt quadrangle", which is model RPSS-AO4E-0,4,4-2428-C.

Manufacturers represented by Suzhou Sanan machine manufacturing limited company (hereinafter referred to as "Suzhou Sanan" or "SANAN") simplify Tianjin Fuyi systems, develop quilt cover/quilt (semi) automatic production equipment with the model of ZDS300, and also reject the automatic overturning process with relatively high equipment cost and manually realize the inside-outside bag overturning process. It is briefly described as follows: firstly, sewing the rectangular outer edges of the fabric, the lining and the filling of the quilt cover by using a quilting machine, and only partially sealing one side, and leaving a mouth for manual subsequent internal and external turning; and then the sewn rectangular outer edge is transversely cut off like a four-edge seam, so that a body primary product for subsequent manual internal and external turning and sealing is obtained.

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

Compared with four-edge seam schemes of manufacturers such as Suzhou QionPai TPET: 1. after the existing four-edge sewing scheme is transversely or longitudinally cut, one group of sewing heads are natural drooping edges which are not fixed at all, the movement amplitude of the sewing heads is very large, and the sewing heads are difficult to position/align. Therefore, the four-edge seam is mainly used for processing towels, sheets and other single-layer materials with cut-off ports on the other two sides being straight lines for alignment/positioning by tightening the two sides; when the adhesive is used for double-layer or multi-layer materials, the free edge is difficult to align, and especially when the adhesive is used for products with flocculent filling layers such as sleeping bags, quilts and the like, the free edge cannot be aligned, and the flocculent filling layers with the cut of the free edge are extremely easy to scatter or fall off when being pulled, so that the adhesive cannot be effectively produced. Compared with a four-edge sewing scheme, the scheme of the invention not only can treat a single-layer structure, but also can seal the edge by the edge sealing mechanism immediately after the flocculent filler is not scattered without purposely positioning/aligning because the sewing head is naturally positioned/aligned and immediately subjected to synchronous edge sealing when being cut out; thus, there is no problem in handling double, triple or even multi-layer structures. 2. While the conventional four-edge sewing scheme can only cut rectangular outer edges in the transverse direction and the longitudinal direction to be used for making rectangular products such as towels, bath towels, bed sheets and the like, the scheme of the invention can be used for making any shape including rectangular shapes through a computer-controlled cutting machine head and a sewing machine head. 3. Although the four sides of the four-side seam can be automatically zipped, the four-side zipper in the scheme can only be a four-section zipper broken at the intersection point of the four sides (because the zipper layout mode in the scheme can only be to firstly lay two longitudinal left and right zippers, after the two zippers and the body primary product are transversely cut together, the two zippers transversely move and are then transversely arranged, and therefore, the four corners of the rectangle are necessarily cut), and the four-side zipper cannot be a common zipper structure such as continuous non-cutting of the four sides (such as a fully-closed bag), continuous non-cutting of the adjacent three sides (such as an envelope sleeping bag) and/or continuous non-cutting of the adjacent two sides. The zipper of the invention can make any turn and turn along with the cutting machine head and the sewing machine head, so that the zipper layout structure which cannot be made by the four-edge seams can be realized.

Compared to the ZDS300 protocol of three amperes in su: 1. the Suzhou three-ampere scheme also has the advantages that one group of seam heads generated after transverse or longitudinal cutting is completely free of fixed free edges, so that the movement amplitude of the seam heads is very large, positioning/alignment is difficult, and the flocculent filling layer of the free edge notch is very easy to scatter or fall off when being pulled. The solution according to the invention does not suffer from these problems. 2. The Suzhou three-safety scheme can only cut rectangular outer edges in the transverse direction and the longitudinal direction to be used for making rectangular products such as envelope sleeping bags and the like, and cannot be used for making other non-rectangular products, and the scheme in the invention can be used for making any shape including rectangular. 3. Because the zipper layout mode under the Suzhou three-security scheme can only be to lay two longitudinal left and right zippers, and the zippers cannot be laid when transversely cutting, the Suzhou three-security scheme can only automatically lay two parallel zippers on opposite sides at most, and not only can continuous zippers on adjacent sides be laid automatically, but also any two-side or changeable continuous non-shearing zipper structures can be laid. The layout structure of the zipper can be realized in the invention. 4. The Suzhou three-safety scheme only saves the procedures of cutting and bag body sewing in the quilt cover/quilt manufacturing process, and the subsequent internal and external turning bags, final sealing and the like are still manually done, so that the degree of automation is not high enough, and the large-scale and manual zero-intervention high-efficiency production cannot be realized.

Compared with the scheme of Tianjin Fuyi RICHPEACE four sides machine: 1. the four-sided machine rich in Tianjin can only be used as a rectangular product, but not as other non-rectangular products, and the invention is applicable to products with various shapes. 2. The four-side machine rich in Tianjin is also characterized in that the four-side zipper is broken at the intersection points of the four sides when the four sides are automatically zipped, and the zipper in the invention can be automatically sewn in a way that the four sides, three sides and/or two sides are not sheared from one to the other as required. 3. The invention has the advantages of complex equipment, high equipment cost, relatively simple process, high equipment integration level and relatively low cost.

The above-mentioned "upper zipper" is an automatic upper zipper, if the above-mentioned scheme is used for making products by means of traditional manual upper zipper, then naturally all four edges of TPET, tianjin Fuyi four-edge machine and four edges of products made of ZDS300 of Sanzhou three-security can obtain continuous non-shearing zipper structure; but the method is obtained by later manual supplementary sewing, has low efficiency and high labor cost, and is not the manual zero intervention high-efficiency production which is needed to be realized.

For the purpose of utilizing the existing mature and stable technology and equipment as much as possible, the process and/or equipment of the invention can be realized in a simpler manner by using various zipper layout devices shown in fig. 28-34 on the four-edge machine at the existing internal seam quilt of the three-security ZDS300 and/or the Tianjin Fuyi RICHPEACE in su. Of course, in order to prevent the seam head from dislocation, deformation or wrinkling, etc., an "inner clamping" fixing mechanism may be required to be added to the existing manner of fixing the seam by the "outer clamping" on the four-sided machine by using the three-security ZDS300 and/or the Tianjin Fuyi RICHPEACE in su. These techniques are not difficult and will not be described in detail.

The above processes are mainly described for the edge sealing process of the edges of the primary products of the sleeping bag and the like, and do not deeply describe how the materials of each layer on the primary product of the body are sewn or fixed. The main principle of sewing is that the main sewing technology of the main body primary product is the computer quilting technology which is mature and reliable. Of course, various common multilayer material fixing techniques such as ultrasonic welding, or even glue compounding/bonding, can be employed without affecting other processes. In terms of the scheme adopting the computer quilting technology, the technical characteristics and essence of the scheme are not essentially different from each other, and the scheme is that the process sequences such as quilting firstly, then cutting, then quilting, even quilting firstly, then cutting, and the like are interchanged, repeated or repeated for a plurality of times. For example, the sleeping bag without turning the bag in the present invention does not make any substantial difference in quilting of the interior of the body blank before or after the body blank is cut out, as long as it does not interfere or interfere with the securing mechanism. In the ZDS300 scheme of Sanan Suzhou, if it is not desired to complete the cutting of the primary product of the body and then quilting is performed once, quilting of the lining and the filling layer must be performed before the cutting, and if the quilting is performed once after the cutting is not completed, the obtained quilt is a quilt with a living surface structure (i.e. 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 becomes a structure with two movable surfaces of the lining and the lining, when the material is used, the lining cannot be formed by self-rolling, and the filling layer between the two movable surfaces and the filling layer are easily torn, shredded, piled and the like, so that heat leak occurs. If the quilting is performed once after the bag is turned over, the problem of double movable surfaces can be solved, but the quilting is performed manually on a quilting machine after the bag is turned over manually, and the improvement of the working procedures and the efficiency is not obvious.

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

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

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

Example 1

A method and equipment for making sleeping bag:

as shown in fig. 1, the face material 5, the filler 6 and the lining material 7 of the sleeping bag are overlapped together and sent into a sewing machine head 16 comprising a quilting machine to be sewn, so that the face material, the filler 6 and the lining material are integrated into a body primary product 11 of the sleeping bag.

The three parts (body primary product 11) are cut to form the edge conforming to the pre-designed shape. For example, the rectangular edges shown in fig. 2 and 3 (of course, other shaped edges such as mummy, oval, cola, or even irregular shaped edges are also possible, as long as precise control by a computer is achieved).

Then, as shown in fig. 1 and 2 (or fig. 3), the edge banding head 14 bands the edge of the primary product 11 with the banding cloth 2. At this time, the fractures of the fabric 5, the filling material 6 and the lining 7 are all wrapped by the wrapping cloth 2 to form a wrapping structure; the hemming structure is fixed by the sewing thread 1 and does not scatter. 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 synchronously performed, 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 arranged behind the cutting mechanism; or the cutting machine head and the edge covering device are mutually independent on the same machine table, and the cutting step is finished first and then the edge covering step is carried out. The two are not very different in technology in essence, but the former has advantages in aspects of preventing fracture loosening and mess, improving production efficiency, technical realizability, reliability and the like.

For ease of understanding, the sewing head 16 and the banding head 14 are shown in FIG. 1 as separate sets of mutually independent sewing devices. To further simplify the production process and equipment, we can even provide the sewing head 16 and the banding head 14 shown in fig. 1 as one piece. That is, the sewing head 16 and the banding head 14 share a set of sewing heads (as shown in fig. 20 to 24) which cooperate with the quilting bed 18 to form the sewing head 16 when quilting the body blank and cooperate with the banding cylinder to form the banding head 14 when banding the cut-out of the edge of the body blank. Such equipment and processes are more simplified.

Similarly, if the hemming cylinder to be fitted with the sewing head is changed to the hemming cylinder, the hemming device in the present embodiment can be converted to the hemming device in embodiment 6 described below (as shown in fig. 27). The principle and the efficacy of the two are not very different, and the hemming cylinder matched with the sewing machine head is changed into the hemming cylinder matched with the sewing machine head, so that the realization difficulty is not great, and more ready-made accessories are available in the market.

Of course, the apparatus may also be provided as a multi-head in order to further increase the production efficiency. Different machine heads synchronously run to respectively bear different technological processes of quilting, edge covering, hemming and/or embroidering marks, and a great amount of time can be saved compared with the step-by-step running, and the production efficiency is obviously improved (as shown in figure 18 or figure 19).

Taking an envelope-shaped sleeping bag as an example, as shown in fig. 2 or 3, the zippers 12 are arranged on the left and right sides and the lower side of the body primary product 11 (i.e., the sewn body of the fabric 5, the filling 6 and the lining 7 in fig. 1) which is rectangular after being unfolded (i.e., the zipper cloth 3 of the zippers 12 is sewn together between the edging cloth 2 and the face 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 the edge banding structure 13 shown in the figure, and the zipper 12 is pulled up to form the human body entrance and exit 15 of the sleeping bag.

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

In use, a conventional envelope-type sleeping bag as shown in fig. 4 can be obtained by folding the rectangle in half and pulling the slide fastener 12 (i.e., the fastener element 4) on the left and right sides thereof as shown by the large arrows on the left and right sides in fig. 1 and 2 (or fig. 3).

( Remarks: for ease of understanding, the dimensions of the products and equipment, the thickness of the materials, and the size of the gaps, etc. in the drawings of the various specifications are not shown to scale; because the microstructure such as the hemming structure of FIG. 1 is not clearly shown at all in the macroscopic views of FIG. 2 or FIG. 3 if drawn to scale )

Finally, as shown in fig. 4: the fractures at the edges of the sleeping bag fabric 5, the filling material 6 and the lining 7 are of a wrapping structure, and the fractures at the edges of the fabric 5, the filling material 6 and the lining 7 are wrapped by the wrapping structure; the zipper cloth 3 of the zipper 12 is sewn to the hemming structure. The zipper may be a closed full length zipper structure covering the entire length of the edge break or a non-fully closed zipper structure covering only the portion of the length of the edge break. The zipper is generally a stacking zipper, and when the length of the clamped zipper reaches a preset value, an automatic cutting machine head is used for cutting off the stacking zipper; of course, a gripper conveyor system (e.g., a robot) under computer control may also be used to convey the strip zippers, if budget permits.

Further, it is even possible to replace the strip or the pack slide fastener with a half-side slide fastener (i.e., only one slide fastener cloth 3 and fastener teeth 4 are used instead of a conventional slide fastener in which a pair of slide fastener cloths 3 and fastener teeth 4 are used in combination): after the half-zippers are clamped as shown in fig. 2, the zipper heads 12A and 12B on the left and right sides of the finished body are put into the same zipper puller, and the zippers on the left and right sides are pulled to the zipper midpoint 12C. Of course, if the zipper 12 is cut at the zipper midpoint 12C, the zippers on either side of the zipper midpoint 12C may be separated and individually clipped by automated equipment. The effect and function of these different zipper clamping means are not significantly different from that of the conventional strip or stacking zippers, but are more convenient to implement by automated equipment.

Still further, as shown in FIG. 3, the half-chain at the midpoint of the chain may be provided as a zipper ring 12D (i.e., when synchronously clamped to the midpoint of the chain, the taping device and the chain conveyor stop moving but the chain conveyor continue to convey the half-chain for a short period of time, and then the taping device and the chain conveyor continue to move along the edge of the fracture along a predetermined path for taping and chain clamping, so that a zipper ring 12D with two ends clamped in the taping is formed, the zipper ring 12D itself being movable rather than clamped and fixed as in the other parts. The zipper ring 12D can be used as a hanger or a finger for hand carrying; more usefully, 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 embodiment is shown in fig. 15. Comparing this with the prior art process diagrams of fig. 13 or 14, it can be seen that the process is simplified very much, the main process is replaced by an automated process, and the labor cost is much lower.

Moreover, the manufacturing process of the sleeping bag does not need the bag turning and/or cotton filling process, the sleeping bag with the zipper can be manufactured with high efficiency and low cost by using an automatic production line, so that the mechanized, automatic, batched, continuous and uninterrupted low-cost production line production of the sleeping bag is realized, the problems that a large number of sews are required to be used in the production of the sleeping bag and the production efficiency is low are solved, and the sleeping bag has good application prospect.

Example 2

The bordure in the above embodiment 1 is a single bordure structure. In order to prevent the edge of the wrapping cloth 2 from being scattered, the wrapping may be made into a double-wrapping structure as shown in fig. 5. The sleeping bag manufacturing apparatus can be obtained by retrofitting and installing a quilting machine which is already very mature and reliable in the prior art, as shown in fig. 18 to 23.

As shown in fig. 5, the fabric 5, the filler 6 (mainly, the sizing cotton mainly comprising the glue-sprayed cotton) and the lining 7 of the sleeping bag are sequentially stacked and then fed into a quilting mechanism to quilt (for avoiding complication, quilting lines are not shown in the figure) the body primary product 11 and/or stitch the edges of the spreading shape of the sleeping bag.

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

The concrete structure of the double-hemming cylinder can be seen in the hemming cylinder 17 in fig. 24 and 25.

And finally, performing the processes of trimming, quality control, packaging and the like. The thread trimming, quality inspection and/or packaging processes can be completely manually executed, or can be realized through partial or complete automatic and intelligent processes on the premise of budget permission.

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

Example 3

In a general sleeping bag zipper, a fabric 5 or a lining 7 contacted with a zipper puller is easily clamped on the inner surface of the puller in the pulling and closing process. The zipper head is used for clamping the lining and/or the fabric of the sleeping bag in the zipper head, so that the problems that the zipper cannot be pulled up or the zipper is unsmooth and the like are caused. To prevent this, an anti-seize strip 8 of a relatively hard or thick material may be added between the fastener tape 3 and the wrapping tape 2 (or backing material 7) during the wrapping, as shown in fig. 6.

The anti-seize strips 8 may be made of webbing, cloth strips or even strip-shaped plastic sheets, as long as they are relatively hard or thick so as not to be easily seized into the slider.

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 together, so that a sleeping bag with the anti-seizing strip 8 as shown in fig. 7 is obtained.

According to the structure and the material of the specific sleeping bag, the anti-seize strip can be arranged between the zipper teeth 4 and the tipping cloth 2 as shown in figure 7, between the zipper teeth 4 and the lining 7, and between the zipper teeth 4 and the lining 5.

Example 4

When a general sleeping bag is used, heat in the sleeping bag is easy to leak out through the meshing gaps of the zipper teeth 4 which are easy to leak out and the zipper cloth 3 made of a very thin woven belt. To prevent such adverse phenomena, the broken edge of the filler may be wrapped in more than once (i.e., the broken filler extension layer 9 shown in fig. 8 is also wrapped in Bao Bianbu) during the wrapping, as shown in fig. 8, to form a thicker, more drum-like wrapping.

When in use, the sleeping bag with the wind shielding strips shown in fig. 9 can be obtained by folding the sleeping bag in half and pulling the zipper teeth 4 on the left and right sides together as shown by the large arrows on the left and right sides in fig. 8: the sleeping bag, when in use, the weather strip covers the zipper teeth 4 and the zipper cloth 3, reducing or preventing heat leakage (commonly referred to as "air leakage" and as such, the structure is referred to as "weather strip") at the zipper teeth 4 and the zipper cloth 3. Whether by the above hemming structure shown in fig. 1 to 9 or by the following hemming structure shown in fig. 10 to 12, a weather strip that makes the thermal insulation performance of the sleeping bag better can be obtained as long as a sufficient filler extension layer 9 is wrapped around and covers the zipper teeth 4 and the zipper cloth 3.

Of course, the weather strip of the hemmed or curled structure may be located not only where there is a zipper, but also where there is no zipper, for example, at the body passageway 15 of the sleeping bag pocket structure shown in fig. 2 or 3. When the edge wrapping or curling structure forms a wind shielding strip at the human body entrance and exit 15 of the sleeping bag, external cold air can be prevented or reduced from entering the sleeping bag through the human body entrance and exit 15 (namely, the shoulders and the neck of a user lying down), and the effect of collar enclosing is achieved.

The hemming cloths 2 may be cotton cloth or flannelette with better skin feel as or close to the sleeping bag inner material 7. Thus, whether the edge-covering structure is used as a wind shielding strip at the zipper or a collar at the human body inlet and outlet 15, the touch feeling of human skin is better, and the direct contact of human skin with the harder zipper teeth 3 and/or the fabric 5 with the waterproof coating at the human body inlet and outlet 15 can be obviously reduced or avoided. Such a sleeping bag would provide a better consumer experience.

Thus, the sleeping bag in this embodiment can be obtained not only by automation at a lower cost, but also with better quality instead.

Example 5

The four embodiments are all obtained by the edge wrapping structure, and the edge curling structure as shown in fig. 10, 11 or 12 can be used instead of the edge wrapping structure to further save material cost and simplify production flow and production equipment. We can simply replace the hemming device in the above embodiments 1 to 4 with the hemming device (see fig. 26 to 27 and fig. 35 to 41). The hemming structure not only can save the material cost of the hemming cloth, but also can simplify the production process and the machine equipment of direct hemming. The sleeping bag making apparatus can also be obtained by retrofitting and retrofitting quilting machines of the state of the art which are already well established and reliable.

Specifically:

First, as shown in fig. 10, 11 or 12, the fabric 5, the filler 6 and the lining 7 of the sleeping bag are sequentially stacked and then fed into a quilting mechanism to perform quilting and sewing of the body primary product 11 (for avoiding complication, a sewing head and a quilting line are not shown in the drawings). Then, the sleeping bag is cut into a shape and a size which are designed in advance, a part (namely a seam head) to be sewn on the edge of the fracture is obtained, and then the seam head is curled. The hemming may include sewing together the three seam ends of the partial filler extension layer 9 (as shown in fig. 11 and 12), or may not include sewing together the two seam ends of the cut edges of the fabric 5 and the lining 7 directly (as shown in fig. 10, that is, a push rod or push plate is disposed on the hemmer and inserted between the fabric 5 and the lining 7, so that the filler extension layer 9 is pushed toward the inner side of the body primary product 11 and away from the seam ends and the hemmed portions of the fabric 5 and the lining 7 before the fabric 5 and the lining 7 are rolled up). The position of the sewing thread 1 may be completely without passing through the filler extension layer 9 as shown in fig. 10, or may be through or more than through the filler extension layer 9 or even the filler 6 itself as shown in fig. 11 or 12.

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

Fig. 11 and 12 show that the hemming structure comprises a filler extension layer 9, and that the sewing thread 1 also passes through the filler extension layer 9, so that the product is more attractive, windtight and/or anti-seize.

And finally, performing the processes of trimming, quality control, packaging and the like.

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 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 together, so that the sleeping bag is one.

Example 6

As shown in fig. 12, various labels 10 including a washing label, a trademark, and/or a warning label may be sewn to the hemming structure and the fastener tape 3.

The label 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 even be located in a suitable location such as the body passageway 15 or the foot without a zipper.

The process can be realized through partial or complete automatic and intelligent processes; the automatic positioning and label placing system can automatically and intelligently stitch on the production line.

Example 7

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

The edge banding head 14 moves along the edge of the sleeping bag body primary product 11, and bites the broken edge (seam head) of the sleeping bag body primary product 11 to carry out banding processes such as banding, hemming or overlocking, etc., to obtain a banding structure 13 or hemming structure, and simultaneously, the zipper 12 is sewn to the banding structure 13 or hemming structure.

The sleeping bag manufactured by the method can be folded in half as shown by large arrows on the left side and the right side in fig. 2, and the zipper racks on the two sides are fixed together by the zipper sliders, so that the conventional envelope sleeping bag can be obtained.

Example 8

FIG. 3 illustrates a method and/or apparatus for making a "sleeping bag with a banding head stationary" in accordance with the present invention.

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

The sleeping bag manufactured by the method can be folded in half as shown by large arrows on the left side and the right side in fig. 3, and the zipper strips on the two sides are fixed together by the zipper sliders, so that the conventional envelope sleeping bag can be obtained.

Example 9

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

The fabric 5, the filling material 6 and the lining material 7 are firstly conveyed into the equipment together in a superposition way through a roll shaft 19; the cutting machine head 20 synchronously cuts the fabric 5, the filling material 6 and the lining material 7 into a body primary product 11; then the sewing machine head 16 and the quilting base 18 are matched with each other to quilt the body primary product 11; the edge banding head 14 and the edge banding barrel 17 are matched with each other to carry out edge banding on the fracture at the edge of the body primary product 11, and simultaneously, various accessory components including a zipper, an anti-seizing strip, a wind shielding strip and/or various labels are sewn between the body primary product 11 and the banding cloth; the quality control and inspection device 21 (such as needle inspection machine, flaw shooting + marking machine, wire cutting machine, blowing machine, etc.) then performs quality control and inspection on the product; finally, the finished body product 23 is output by means of a folding and packaging device 22 (for example, a shirt folding and packaging machine which is already in great use in the market is converted into a quilt cover or a quilt folding machine, or a roll cover, a plug-in package, a packaging machine or the like is additionally arranged).

After unreeling the fabric 5 and/or the lining 7 of the present embodiment, a cloth inspecting mechanism may be further added before entering the substantial processing step. Once the defective cloth is detected, proper marking, skipping, repairing, even stopping for material changing and other treatments can be performed under the control of a computer so as to avoid the subsequent processing procedures to continue processing the defective cloth, thereby causing the material loss of other materials or making unqualified products.

Of course, in this embodiment, other different mechanisms such as automatic feeding, multi-layer material compounding, cloth splicing or cutting, pattern recognition high-speed shooting instrument, printing, mark scalding, embroidery, quilting, cotton loosening, cotton carding, thread end blowing or sucking device, code spraying, marking, statistics, rolling, automatic packaging and/or automatic storing and transporting can be added, and the above procedures can be synchronously performed under the accurate control of a computer so as to further improve the degree of automation, reduce the participation of manpower or manpower, and even realize a completely unmanned black lamp factory except for feeding, removing and unloading.

For ease of understanding, the cutter head 20, the sewing head 16, and the banding head 14 in this embodiment are independent of one another; in actual production, any two or even all three of the cutter head 20, the sewing head 16 and the banding head 14 may be integrated into a single unit to improve production efficiency, reduce equipment costs and/or improve machine reliability, etc.

The process diagram in this embodiment is shown in fig. 15. Comparing this with the prior art process diagrams of fig. 13 or 14, it can be seen that the process is simplified very much, the main process is replaced by an automated process, and the labor cost is much lower. Moreover, the manufacturing process of the sleeping bag does not need the bag turning and/or cotton filling process, the sleeping bag with the zipper can be manufactured with high efficiency and low cost by using an automatic production line, so that the mechanized, automatic, batched, continuous and uninterrupted low-cost production line production of the sleeping bag is realized, the problems that a large number of sews are required to be used in the production of the sleeping bag and the production efficiency is low are solved, and the sleeping bag has good application prospect.

Example 10

The above embodiment 9 is realized by modifying the existing computer quilting machine. The operating plane of the existing quilting machine is generally a horizontal plane as shown in fig. 16. The operating plane of the automatic sleeping bag producing apparatus of the present invention need not be a horizontal plane as shown in fig. 16, but may be a compact space folding structure as shown in fig. 17. Thus, the occupied area of the machine equipment can be reduced, and the factory renting cost and the like can be saved.

Example 11

FIG. 18 shows a sleeping bag making apparatus of the present invention retrofitted with a quilting machine having a table 28 with the cutting head 20, sewing head 16 and banding head 14 of the functional units being separated from each other. The cutting head 20, the sewing head 16 and the banding head 14 perform the tasks of cutting, quilting and taping, respectively. When two or three of any functional devices cannot be mutually influenced, each functional task can be executed simultaneously or synchronously; if any, one or both of the functional units affected can be retracted through the guide rails 26 to one or both ends of the main frame 27, freeing up space above the table 28 for the functional units that need to perform tasks to operate.

Under the accurate control of a computer, the cutting machine head 20, the sewing machine head 16 and the edge banding machine head 14 are respectively hung below the machine head mounting frame 24 through the hanging rods 41, can respectively move up and down and rotate through the hanging rods 41, move back and forth along the extending direction of the machine head mounting frame 24 through the positioning belt 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 various arbitrary stitch processing operations including straight lines, oblique lines, fold lines, turning lines and the like.

In order to avoid the head mount 24, the suspension bar 41 and/or the head etc. from contacting, colliding or interfering with other parts or materials to be processed, the head mount 24 and/or the suspension bar 41 etc. may be provided in a tiltable or bendable structure, and even a multiaxial robot may be used instead of the head mount 24 and/or the suspension bar 41.

The zipper 12 is fed to the banding head 14 through a limiting aperture 31 provided in the head mount 24 or beam. The edge banding head 14 can be a hemming device, a serging device (serging device), a tightening device, etc. respectively or simultaneously, and can be used for sewing the zipper 12 to the edge banding place while the edge banding is performed, so that the synchronous completion of the edge banding and the zipper feeding is realized.

The base 28 is provided with a plurality of air holes 29. When the material on the bearing platform 28 needs to be fixed, the air holes 29 can suck air to the inner side of the bearing platform 28 to generate negative pressure, and the material covered on the air holes 29 can be adsorbed on the bearing platform 28 to achieve the purposes of fixing the material, positioning and the like. When the material on the platform 28 is required to move (for example, when the material on the platform 28 is overweight to affect material conveying or when the material is required to move, rotate at a higher speed or with a larger degree of freedom), the air holes 29 can blow air to the outside, so that the material covered on the air holes 29 can be blown off the platform to a certain extent, and the purposes of supporting the material, reducing material conveying resistance, adjusting the material direction and the like are achieved. In addition, various rollers can be arranged on the bearing platform 28, and the rollers can roll in a coordinated mode under the control of a computer so as to enable materials on the rollers to move towards a preset direction.

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

Example 12

Fig. 19 shows a sleeping bag making apparatus in which the sewing head 16 and the banding head 14 of the present invention are provided as one body. The sewing head 16 and the banding head 14 can be operated simultaneously or separately, as desired for a particular process. This has the advantage that the equipment material investment, the equipment volume and the like can be reduced.

Example 13

FIG. 20 illustrates a sleeping bag, garment, cushion or blanket making apparatus of the present invention wherein the cutting head 20, sewing head 16 and banding head 14 are all integrally provided together. The cutting head 20, sewing head 16 and banding head 14 can be operated simultaneously or separately, as desired for a particular process. This has the advantage that the material input and the volume of the device can be further reduced.

Example 14

Fig. 21 shows an apparatus for making a sleeping bag, garment, bag or mattress of the present invention without a table, but with the cutting head 20, sewing head 16 and edge banding head 14 all configured as an integrated head.

Under the accurate control of a computer, the integrated machine head can move forwards and backwards 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 machine head or each functional device can move forwards, backwards, tilt, change direction, turn, do curve motion and the like. In this way, the functional devices integrated in the integrated head can cover the entire spatial area for processing the product without dead angles.

To accommodate functional devices requiring a shoe such as quilting, a quilting bed 18 may also be provided in the lower portion of the apparatus as shown in fig. 21. The quilting bed 18 can be fixed to the bottom head mount and can be free to move independently of the head mount.

Fig. 22 shows the apparatus of fig. 21 when making a sleeping bag: the fabric 5, the filling material 6 and the lining material 7 are simultaneously fed into the sleeping bag manufacturing equipment; quilting the body blank 11 by a sewing machine head 16 in the integrated machine head (quilting stitch on the body blank 11 is not shown in fig. 22 to avoid too complicated a picture of the drawing in the specification); then the fixed frame 48 is pressed down/covered onto the quilted body primary product 11 under the control of the control rotating shaft 49, the fixed frame 48 above the body primary product 11 is matched with the fixed frame below the body primary product 11 to fix the body primary product 11 properly or make integral movement after being fixed, so as to avoid or reduce excessive deformation or displacement of the body primary product 11 and edge fracture (seam) thereof in the edge sealing process (if a bearing platform is arranged on the lower side of the body primary product 11, the bearing platform can be matched with the fixed frame or the fixed plate above the body primary product to realize fixed or synchronous movement); cutting the shape of the primary product 11 by a cutting machine head 20 in the integrated machine head according to the shape preset in a computer; the hemming cylinder 17 (or hemming cylinder, or hemmer) and the sewing needle (which may be used simultaneously with the sewing needle in the sewing head 16) in the hemming head, which are also provided in the integrated head, immediately follow the cutting head 20, and the cut-out generated by the cutting is immediately hemmed. The zipper 12 is synchronously conveyed to the hemming cylinder 17, the hemming cylinder and/or the serger of the edge banding machine head 14 through a limiting hole 31 arranged at the machine head mounting frame 24 or the beam frame and the like under the control of a computer and/or a machine, and the zipper 12 is sewn to the edge banding part at the same time of edge banding; the synchronous zipper up is realized at the same time of edge sealing, and the finished product 23 of the body is obtained.

The fixing frame 48 may be in various regular shapes such as a 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, etc., or may be in various irregular shapes completely the same as the shape of the body product to be manufactured. In any event, however, the dimensions of the retaining frame 48 should be just one turn smaller than the finished body 23, leaving a cut edge (i.e., a "stitch") about 3mm to several cm wide for the edge sealing process to form edge sealing structures including hemming structures, and overlocking structures.

The fixing frame 48 is not limited to the case that only the upper and lower sets are distributed on the outer sides of the sewn product as shown in fig. 21 and 22 for the clamping and moving operations, and can also be partially positioned inside the primary product of the body (shown as a fixed frame 48B in fig. 38) and partially positioned outside the primary product of the body (shown as a fixed frame 48 in fig. 38) as shown in fig. 38, and the inner and outer parts are matched with each other to perform better clamping or moving. The source of the clamping force may be a mechanical pressing type clamping as shown in fig. 21, 22, 36, 37, or the like, or a clamping by a magnetic force or electromagnetic adsorption or the like capable of penetrating the material layer to be clamped.

The hemming cylinder, the hemming device and/or the flat seaming device and the like of the machine head part should be provided with a detachable and interchangeable structure so as to adapt to different processing technologies and product requirements as much as possible.

Referring now in further detail to the details of the above manufacturing process, FIG. 24 is an enlarged schematic view of a handpiece employing a taping cylinder 17 as shown in FIG. 22: the cutter head 20 is provided with a blade 38 (or a laser beam for cutting) for cutting the body primary product 11, and the edge-covering tube 17 immediately surrounds the cut-off opening after the blade 38. The slide fastener 12 (i.e., the slide fastener cloth 3+the fastener teeth 4 in the drawing) is synchronously conveyed to the hemming drum 17 together with the hemming cloth 2, and the slide fastener cloth 3 is sewn to the hemming position while hemming, thereby realizing hemming and edge slide fastener.

To ensure a banding effect, a cloth brush 50 may be provided after the blade 38 and before the taping cylinder 17. Cloth brush 50 may be rotated forward, reversed, turned and/or evacuated; the device can be integrated with the machine head, and can also be an independent movement mechanism which can be separated from the machine head; the single cloth brush can be arranged into one group, two or more cloth brushes can be arranged into one group, and multiple groups can be mutually matched, so that various different effects such as better smoothing, curling, tightening and the like are achieved. Fig. 24 shows two cloth brushes 50 provided after the blade 38 on the upper side of the body primary product 11 and before the hemming cylinder 17, which form a group to sweep the edge (seam) of the cut-off portion of the body primary product 11 to the left, thereby avoiding or reducing the folding, curling, displacement, etc. that easily occur after the cut-off portion of the body primary product 11. Preferably, two cloth brushes 50 are also provided at this time on the lower side of the body primary 11, after the blade 38 and before the hemming cylinder 17. Such a cloth and alignment effect may be better. Of course, the cloth arranging device does not necessarily have to be a rolling brush, but may be a brush such as an air blowing port, a scraper, a doctor blade, or the like; can be used separately or simultaneously as long as the effects of avoiding folding, curling and deforming are achieved without affecting other procedures.

In addition, a needle hole 42 or a needle passing groove may be formed in a banding stopper 56 of a banding structure such as a hemmer, a hemming cylinder 39, a hemming plate 51, a hemming cylinder 17, etc. as shown in fig. 24 to 41, so that the sewing needle 40 can conveniently pass through the hemming cylinder or the hemming cylinder 17, etc. to perform sewing. Of course, the sewing needle 40 may be arranged behind the edge sealer limiting plate 56 and immediately following the edge sealer limiting plate 56, and the folded hemming cloth 2 and the aligned zipper cloth 3 may be sewn to the fracture of the body primary product 11 at once or simultaneously, thereby obtaining the hemming structure with the zipper.

Fig. 25 is a schematic cross-sectional view of the portion of the binding cylinder 17 of fig. 24: the zipper cloth 3 of the zipper is synchronously limited in a zipper cloth clamping groove formed by the edge covering barrel 17 and the zipper arranging 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 pulled to the left as shown in fig. 25 (this can be achieved by the zipper introduction direction, for example, by allowing the zipper to be always introduced obliquely from the upper left of the nose part as shown in fig. 24), the entire zipper will always be securely confined in the slot for quick passage, thereby achieving the arrangement, positioning and alignment of the zipper cloth. The sewing needle 40 is arranged behind the hemming cylinder or penetrates through the needle passing hole 42 on the hemming cylinder and simultaneously pierces the edge covering cloth 2, the zipper cloth 3, the fabric 5, the filling material 6, the lining material 7 and the like which are well rolled, the sewing thread 1 is led to the lower sides of the edge covering cloth 2, the zipper cloth 3, the fabric 5, the filling material 6, the lining material 7 and the like from the upper sides of the edge covering cloth 2, the zipper cloth 3, the fabric 5, the filling material 6, the lining material 7 and the like, and is combined with the sewing thread in the rotating shuttle at the lower sides of the edge covering cloth and the lining material to form a loop structure of the sewing thread, so that synchronous edge sealing and zipper feeding can be realized.

The method and the equipment in the embodiment realize simultaneous feeding, quilting, simultaneous cutting, synchronous edge covering and synchronous zipper feeding of the fabric 5, the filling 6 and the lining 7, and finally the finished sleeping bag body 23 comes out of the machine, thereby avoiding time-consuming and labor-consuming manual step-by-step processing, semi-finished product transferring and the like.

In addition, one or more hemming devices, and/or overlocking devices, etc. may be integrated on one machine head to perform operations such as hemming, and/or overlocking while cutting and zipping, etc. to avoid or reduce the travel of the machine head, walk around, and/or repeat/reciprocate for different operations on the same track. For example: the right side fracture cut by the cutting device 20 forms the taping structure 13 with the zipper 12 by the taping cylinder 17 and the sewing needle thread, and the taping cylinder 17 is opened rightward in fig. 22; at the same time, a hemming cylinder (not shown for brevity) with an opening toward the left may be provided at the left side of the hemming cylinder 17, and the left side fracture cut by the cutting device 20 forms a hemming structure by the hemming cylinder and another set of sewing needle threads. That is, if the hemming tube 17 with the opening to the right and the hemming tube with the opening to the left are simultaneously installed at the head part shown in fig. 22 so that the two are back-to-back and the opening is directed to just one left and one right, the left cut out by the cutting device 20 in fig. 22 can be hemmed and the right cut out can be hemmed at the same time. When needed (as shown in fig. 22, when two body primary products are just cut), edge wrapping and edge curling can be performed simultaneously, edge curling is performed on the left body primary product, edge wrapping is performed on the right body primary product simultaneously, and one of the edge wrapping device and the edge curling device is performed according to pre-designed position data by a computer, and the two are not performed at the same time or only performed at the same time; and the zipper, the label and the like can be simultaneously arranged, so that the utility model has multiple purposes and one stone and multiple birds; 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.

In addition, the curved connecting portion of the left side of the taping cylinder 17 in fig. 24 and 25 may be ground into a sharp edge and projected forward, i.e., the blade 38 is fixed to the taping cylinder 17 without providing the cutter head 20 additionally. If desired, the projecting sharp edge may replace the blade 38 to directly cut through the corresponding material to be sewn, thereby integrating the cutting device 20 and its blade 38 into the taping cylinder 17.

By the device in the embodiment, the process of feeding the head material and discharging the head finished product can be realized, and the device is a great improvement on the production process and the device of the sleeping bag.

Example 15

In contrast, fig. 26 shows a common hemming structure: the fabric 5, the filler 6 and the backing 7 are wound into the hemming cylinder 39 together, and the sewing needle 40 sews the hemmed structure in the hemming cylinder 39 to ensure that the hemming structure does not unravel. The sewing needle 40 may be sewn through a needle passing hole 42 in the hemming cylinder 39 as shown, or the hemming cylinder may be not provided with a needle passing hole but the sewing needle is directly attached to or immediately attached to the hemming cylinder 39, and the curled structure discharged from the end of the hemming cylinder 39 is sewn so as not to scatter the curled structure. This is a common solution and need not be described in more detail.

Fig. 27 shows a slide fastener arrangement device according to the present invention provided on a hemming cylinder 39, corresponding to the conventional hemming cylinder shown in fig. 26. A zipper cloth catching groove is formed on the inward folding tongue of the conventional hemming cylinder 39 shown in fig. 26 by a zipper disposing 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 pulled to the left as shown in fig. 27, the entire zipper is always securely confined in the slot and quickly passed, thereby achieving the arrangement, positioning and alignment of the zipper cloth. The sewing needle 40 is directly behind the hemming cylinder 39 or passes through a needle passing hole in the hemming cylinder while penetrating the zipper cloth 3, the fabric 5, the filler 6, the lining 7, etc. which have been aligned by these stopper structures, to achieve synchronous hemming and zipping.

Example 16

Examples 14 and 15 are examples of "zipper disposed in the neck and zipper teeth disposed outside the neck", and examples of "zipper disposed in the neck and zipper disposed outside the neck" are also possible in the present invention.

As shown in fig. 29, a slot type fastener spreader 45 is first manufactured such that the size of the slot opening 46 is smaller than the thickness of the fastener teeth 4 but larger than the thickness of the fastener cloth 3 or the minimum thickness of the fastener cloth 3 after being pressed. When the fastener element 4 of the slide fastener is inserted into the slot and the sewing process is started, the fastener element 4 cannot be pulled out to the right through the slot opening 46, and the fastener cloth 3 can be pulled out to the right through the slot opening 46. Thus, when the slide fastener is sewn, as shown in fig. 28, the fastener element 4 always moves only inside the clamping groove, and the fastener cloth 3 extends below the sewing needle outside the clamping groove, and is synchronously conveyed and threaded together with the sewn fabric 5, the filler 6 and the lining 7. Accordingly, as long as the fastener spreader 45 shown in fig. 28 and 29 is fixed to the presser foot 44 of the sewing mechanism by means including a clamp, screw, rivet, or even electric welding so that the fastener cloth 3 protruding from the neck opening 46 is always located 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

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

As shown in fig. 30, the slide fastener is arranged on the inner side of the sewn article by the slide fastener arranging device 45 sandwiched between the fabric 5 and the lining 7 (as can be seen from comparison between fig. 28 and 30 or comparison between fig. 29 and 31, the slide fastener arranging device 45 is the same as that shown in fig. 28/29 and 30/31, except that the slide fastener is arranged in one direction in the left-right direction). In this case, the zipper teeth 4 are located outside the seam trace formed by the sewing thread 1, and these banding is not necessarily beautiful in visual effect due to the presence of the edge fractures of the face fabric 5, the filler 6 and the backing 7. Therefore, as shown in fig. 32, the fastener grooves for disposing the zipper are also extended into the inside of 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 zipper teeth 4 are positioned inside the seam lines to be formed by the sewing thread 1. Because the zipper arranger 45 always moves in front of the sewing needle 40 and does not interfere with or affect the movement of the sewing needle, although the zipper arranger 45 is inside the pocket formed by the sewing thread 1 and the fabric 5, the lining 7, the sewing of the pocket is not affected; the zipper dispenser 45 will withdraw from the space formed by the panel 5 and the backing material 7 from the last seam area before the bag is completely sewn. The slide fastener thus laid is fastened by the sewing needle 40 and the sewing thread 1 immediately thereafter, and then becomes a slide fastener wrapped inside the bag-like structure as shown in fig. 34. The bag-shaped structure is essentially indistinguishable from the traditional bag-shaped structure manufactured by manual sewing, and the turned-out zipper sewing position can not see the fracture or thread end only by turning the bag-shaped structure inside and outside, so that the product is more attractive (at the moment, the unsightly fracture is turned into the inner side of the bag body which is invisible to eyes). Of course, if the bag-shaped structure is to be turned inside out, the relative positions of the front and back faces of the cloth of the fabric 5 and the lining 7 and the filler 6 must be designed in advance, otherwise, adverse phenomena such as that the front and back faces of the lining are not opposite, the filler is exposed outside the bag-shaped structure and the like can occur after the inside and outside turning.

Through 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, the phenomenon that the zipper is additionally arranged manually is avoided, and compared with the prior sleeping bag production process, the efficiency, the time and the labor cost are high; the subsequent bag turning and sealing procedures can be completely the same as various fully manual, semi-automatic or fully automatic quilt cover turning procedures which are known at present.

To reduce the investment in "inside and outside tipping devices" which are relatively expensive and less reliable, the various embodiments of the non-tipping pouches described above are clearly better in terms of process, and the problem of unattractive edges of these embodiments can be masked and solved by hemming, taping, overlocking or stretching, etc.

In order to facilitate the zipper layout device 45 to be inserted 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 head) of the fabric 5 is properly lifted, a suction nozzle is arranged below the fracture edge (lower side seam head) of the lining 7, and the fracture edge of the lining 7 is properly lifted, so that a neutral space is formed between the fracture edges of the fabric 5 and the lining 7, and the zipper layout device 45 is conveniently inserted between the fracture heads of the fabric 5 and the lining 7.

For ease of understanding, the left and right sets of zipper applicators 45 and sewing needles 40 are shown in FIG. 34. In fact, if a set of zipper dispenser 45 and sewing needle 40 were provided for further equipment cost savings, a complete zipper-up and edge sealing process could be achieved by having the set of zipper dispenser 45 and sewing needle 40 move from one zipper end 12A or 12B shown in FIG. 2 or FIG. 3 to the other along the path of the zipper 12 shown in those figures. The zipper dispenser 45 and the sewing needle 40 are not difficult techniques to turn or reverse under computer control. The arrangement of the plurality of sets of zipper layout devices 45 and sewing needles 40 has the advantage that the production efficiency can be improved, but the equipment investment can be increased; the single set of zipper dispenser 45 and sewing needle 40 has the advantage of reducing the equipment investment, but the production efficiency is somewhat reduced; the optimization scheme is specifically selected according to the product characteristics, the productivity requirements and the like.

Therefore, according to specific products and process requirements, the process and equipment can avoid the process of internal and external overturning, and can also keep the process of internal and external overturning; it can be achieved by changing the zipper dispenser 45 or changing the position and orientation of the zipper dispenser 45 as appropriate.

Example 18

The above examples are examples of using the method or apparatus of the present invention to produce products of double or multi-layered construction including face and back materials, but the method and apparatus of the present invention are not limited thereto and may be applied to single-layered construction (e.g., fully automated sewing of products such as mats, blankets, towels, etc.) to improve upon or replace these existing single-layered automated sewing devices. In particular, the present invention provides the obvious advantage of eliminating the need for an additional separate blanking process by the machine apparatus of the present invention, and can be retrofitted or substituted for existing methods and apparatus. For example:

The crimping flap 51 shown in fig. 35 is first made: the hemming flap 51 is composed of a hemming riser 51A and an elongated hemming diaphragm 51B, which can be bent from the same stainless steel sheet, can be manufactured by welding and polishing two stainless steel sheets, and can be manufactured by injection molding or glass fiber reinforced plastic molding. The crimping plate 51 may be secured to a hand piece or other control device by a mounting hole 51C for relative movement with the cut edge of the body blank 11 as shown under the control of the hand piece or control device.

In processing hemming of a single layer of material, the cloth brush groups of different rotational directions (two groups of cloth brushes in fig. 35 are a cloth brush 50A rotated counterclockwise and a cloth brush 50B rotated clockwise, respectively) are arranged in front of and laterally of the hemming plate 51. The cloth brush 50A rotating counterclockwise in front of the curled flap 51 brushes the cut-out opening of the body primary product 11 outward (i.e., to the right in the drawing) to avoid folding, twisting, excessive displacement, etc. of the cut-out opening; the cloth brush 50B on the side surface of the curled flap 51 rotates clockwise to sweep and press the cut-off opening of the primary product 11 to the upper side (i.e. the left side in the figure) of the curled transverse plate 51B so as to prevent the cut-off opening from bouncing off the curled transverse plate 51B; the hemming riser 51A may be secured to the hemming head, the cutting head and/or the sewing head to achieve synchronous movement. Once the hemming flap 51 and the edge of the cut-out opening of the body primary product 11 are relatively moved and the two sets of cloth brushes 50A and 50B are rotated in respective directions, the edge of the cut-out opening of the body primary product 11 is swept and flattened onto the hemming diaphragm 51B by the cloth brush 50B; the sewing needle 40 is fastened or closely attached to the hemming plate 51B, and immediately the edge (head) of the cut-off opening, which has not yet been released or bounced off from the hemming plate 51B, is sewn and fixed, so that the desired hemming structure 39 is obtained (the hemming structure 39 behind the sewing needle 40 in fig. 35 is not purposely closed for easy understanding, in practice, the upper and lower layers of material are actually closely sewn together once they are pierced by the sewing needle 40 and sewn by the sewing threads 1 on the upper and lower sides).

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

Fig. 35 shows the state of the crimping flap 51 in operation in a perspective view, and fig. 36 shows the state of the crimping flap 51 in operation in a front cross-sectional view.

The fixing frames, the cloth brush 50 and the hemming folded plate 51 can be precisely matched with the 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 provided, a suitable zipper dispenser is simply attached to the crimping flap 51, and no further description is necessary.

Example 19

The crimping flap 51 of example 18 can be used not only to handle bulk blanks of a single ply of material, but also to handle bulk blanks of two or more plies of material. As shown in fig. 37, the hemming effect in example 18 can be similarly achieved by superimposing two or more layers of material of the body blank together and selecting several sets of brush 50 (clockwise rotating brush 50B is shown and counter-clockwise rotating brush 50A is not shown) of appropriate size, direction and rotational speed. That is, the present example and example 18 differ only in that a single layer of material is replaced with a double layer of material.

Example 20

The hemming direction of the two or more layers of the material of example 19 was single, either upward or downward simultaneously, but in practice, there would be situations where the upper or upper layers of the two or more layers of material need to be hemmed up, the lower or lower layers need to be hemmed down. In the present invention, this object can be achieved by providing the separator 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, so that the bristles of the cloth 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 material layer 54 from contacting the first material layer 53. Thus, the upper and lower cloth brushes 50 independently operate, and the upper first material layer 53 is curled upward and the lower second material layer 54 is curled downward, so that they do not affect each other (the cloth brush 50B rotating clockwise is shown in fig. 38, and the cloth brush 50A rotating counterclockwise before it is not shown).

If a zipper is also desired, one or more sets of suitable zipper applicators may be attached to one or more of the crimping flaps 51, and need not be repeated.

Of course, to facilitate the insertion of the spacer 52 between the first material layer 53 and the second material layer 54, a suction nozzle may be disposed above the fracture edge of the first material layer 53, where the first material layer 53 is properly lifted, and a suction nozzle may be disposed below the fracture edge of the second material layer 54, where the first material layer 53 is properly lifted, such that a relatively large gap is formed between the first material layer 53 and the second material layer 54 to facilitate the insertion of the spacer 52.

Example 21

The zipper layout devices in the above embodiments are all parts which are attached to the heads of edge banding machines such as a hemming cylinder, a hemming plate, a hemming cylinder, a serging machine and the like and have relatively small sizes, and the sewn parts are immediately pushed away from the edge banding machine head after the zipper cloth is fixed by the sewing threads.

If the size of the sewn object is large or the technological process requires the support of the edge banding machine head, the fixed size is large or the shape of the product is complex, the hemming strip 47 shown in fig. 39 to 41 can be adopted: the hem strip 47 is inserted or wrapped into the hem before the hem seal, and the zipper cloth 3 is also partially wrapped into the hem; the sewing thread 1 does not pass through the hemming strip 47 and the hemming strip 47 may be provided in a smooth flat strip, loop, ring, sheet or other suitable shape. After the hemming structure is made by the sewing needle 40 and the sewing thread 1, the smooth and flat hemming strip 47 is withdrawn. Since such a hemming strip 47 can be made of a material excellent in strength such as stainless steel, it is not difficult to perform.

If the tag strip 47 is not withdrawn, the resulting structure is the usual welt of the bag at the seam of the outer surface. The automation of the wrapping edge is lower in cost, higher in efficiency and more stable and reliable in quality than the manual operation of the wrapping edge in the known case.

In one-to-one correspondence with the single-layer one-way hemming structure in fig. 35 and 36, the double-layer one-way hemming structure in fig. 37, and the double-layer two-way hemming structure in fig. 38, fig. 39 in this embodiment shows a single-layer one-way hemming structure in which the hemming strip 47 is extractable or cored, fig. 40 shows a double-layer one-way hemming structure in which the hemming strip 47 is extractable or cored, and fig. 41 shows a double-layer two-way hemming structure in which the hemming strip 47 is extractable or cored.

Example 22

Fig. 43 and 44 show a vest made with the double-layered bi-directional hemming structure of embodiment 20 or embodiment 21.

As shown in fig. 42, the front and rear panels of the vest are erected onto the unwind stand of the apparatus of the invention in the form of two rolls of uncut fabric to produce the vest of fig. 43 and 44 directly, quickly and efficiently in a "manual zero intervention" manner. The first material layer 53 and the second material layer 54 on the left side of the nose mount 24 in fig. 42 are uncut materials, rather than having been cut separately into cut pieces and then machined as in conventional processes or Sewbots company solutions. The process and equipment are clearly better than the Sewbots company solutions.

With reference to fig. 42 and 43, first as described in example 20 or example 21, the following are sequentially:

The first material layer 53 and the second material layer 54 are firstly synchronously conveyed to the cutting machine head 20 by the roller 19, a photograph of the input material is photographed in real time by a high-speed photographic apparatus (not shown in the figure), and after the real-time comparison of a preset cutting typesetting diagram in a computer system is carried out, the roller 19 stops rotating, and the conveying of the cloth in an operation space is stopped (the cloth on the unreeling device can be continuously conveyed by setting a hanging bamboo curtain and the like as a buffer cloth, so long as the length of the subsequent buffer cloth is just enough for the next action cycle).

After the cloth in place and the movement stopped in the operation space, the one or more fixing frames 48 controlled by the control shaft 49 are fixedly fixed on the first material layer 53 and the second material layer 54 which are not cut and are stacked together to prevent them from being deformed or displaced. As shown in fig. 42, these fixing frames 48 have been previously formed in a shape corresponding to the vest, and the edges of the fixing frames 48 may be left with sufficient and right stitch gaps for the heads including the cutting blade (or laser head) of the cutter head 20, the banding head 14 and the sewing means to pass through after fixing.

Then, the cutting blade (or laser head) of the cutter head 20 starts to operate, and the primary body 11 is cut in a predetermined vest shape and size. The edge part of the cut opening of the cut primary product is a seam part capable of swinging up and down, and a sucking disc or an air suction head (not shown in the figure) following the cutting knife (or the laser head) sucks the cut primary material layer 53 up to a point and sucks the corresponding secondary material layer 54 down to a point, so that a small opening capable of inserting the partition plate 52 shown in fig. 38 or fig. 41 into the edge layer of the primary material layer 53 and the edge layer of the secondary material layer 54 is obtained. After the spacer 52 is in place, as shown in fig. 38 or 41, each set of cloth brushes 50 is abutted against the joint near the spacer 52, that is, the edge layer formed by the cut-out of the first material layer 53 and the second material layer 54 and the outer edge of the fixing frame 48. Under the combined action of the cloth brush 50, the hemming flap 51 and the sewing mechanism, the hem 58 of the first material layer 53, the armholes 33 and the edge of the cut-off opening of the neckline 32 are turned upwards to hemm (the size of the machine head is too small to be shown to scale in fig. 42 compared with the size of the whole machine, but reference can be made to a hemming structure 34 turned forward/outward at the hem 58 of the front piece of the vest in fig. 43); the hem 58, armholes 33 and cut edges of the neckline 32 of the second material layer 54 are turned down to be curled (the size of the machine head is too small to be shown to scale in fig. 42 compared with the size of the whole machine, but reference is also made to a hemming structure turned backward at the hem of the rear piece of the vest in fig. 43); the left and right sides and the two shoulder parts of the upper and lower layers of material after the hemming are hemmed to obtain a hemmed structure 57 as shown in fig. 43 (of course, the two sides and the shoulder parts may be hemmed and/or hemmed, etc. except that the hemming, hemming and/or hemming operations are performed on the two layers of cloth of the first material layer 53 and the second material layer 54 at the same time, and the cut-off (seam) of the first material layer 53 and the second material layer 54 are sewn together; while the hem 58, armholes 33, and cut edges of the neckline 32 are provided by two separate hemming, serging and/or taping operations performed on only one of the single layers of material of the first and second layers of material 53, 54, the first and second layers of material 53, 54 are not sewn together so as to allow the head or limbs of the consumer to extend from the hole-like structure formed by the unstitched materials), an uninverted vest (fig. 43 shows an exploded view of the front and rear panels as separated from each other for ease of understanding, and in fact the front and rear panels are tightly sewn together by a serging structure 57 formed by the sewing thread 1 shown in the drawings) is provided as shown in fig. 43.

After the vest of fig. 43 is turned inside out, the common vest shown in fig. 44 can be obtained: the hems 58, neckline 32 and armholes 33 of the front and rear pieces of the vest are made into hemming structures 34 to achieve the purposes of beautiful appearance and preventing cloth edges from scattering, and the left and right armpits and the upper parts of the two shoulders are provided with hemming structures 57; the stitches of the hemming structure 34 and the overlock structure 57 are turned over to the inside of the vest and are not exposed for aesthetic purposes.

In this embodiment, the first material layer 53 and the second material layer 54 are directly connected to the machine in a roll material manner under the condition of no cutting, after a plurality of or a plurality of vests are optimally typeset by a computer cutting system (the body primary products of a part of single vests can be inverted, inserted and even rotated on a typesetting plane to reduce the material waste during cutting), the vests are cut and sealed one by the integrated machine head controlled by the computer, so that the full-automatic production of zero manual intervention of the machine, wherein the material of the whole width (about 1.5 m) of the whole width of the machine is fed, and the vests of the single product width (about 0.5-0.8 m) are discharged, is realized. However, how to interactively insert and discharge the most amount of the vest with the width of about 0.5-0.8 m on the cloth with the width of about 1.5 m in a mode of 'least material waste', is a very mature technology of the existing computer typesetting system and has no special difficulty.

Under the precise control of a computer and typesetting system, as shown in fig. 44, the trademark 55 can be manufactured to the proper position of the primary product of the vest body by means of automatic silk-screen printing, pad printing, heat transfer, embroidery/embroidery, stitching, bonding and the like before being turned inside out (even before being cut out, as long as the trademark position is determined by computer typesetting).

The fixing frame of the invention is generally a plane type upper and lower symmetrical structure, and clamps the primary product of the body from the upper and lower directions respectively (as shown in figure 37); however, the fixing frame in the present invention is not limited to the planar type upper and lower symmetrical structure. As shown in fig. 38, the fixing frame 48 can clamp the primary product of the body from the up and down directions, and can be inserted into the sewn material at intervals to form a three-layer fixing structure (as shown by the fixing frame 48B in fig. 38), so that the fixing effect is better and the manipulator operation is facilitated. Of course, the fixing frame 48B in fig. 38 may be further configured as a double-layer structure, wherein an upper layer corresponds to the upper fixing frame 48 outside the sewn material, and a lower layer corresponds to the lower fixing frame 48 outside the sewn material.

The internal fixation frame 48B may be used in combination with the spacer 52 as shown in fig. 38, or the spacer 52 of fig. 38 may be replaced with various applicators 45 such as those shown in fig. 28-33, i.e., the internal fixation frame 48B may be used in combination with various applicators 45 to apply and stitch together such as zippers, drawstrings, core straps, etc. into the edge sealing structure of the upper and/or lower layers.

Further, the fixing frame 48 and/or the internal fixing frame 48B are not necessarily limited to a planar type. If necessary, the fixing frame 48 and/or the inner fixing frame 48B may be provided with a concave-convex curved frame (or a concave-convex curved fixing plate or fixing block, as long as the operation of other devices or the material transportation are not affected, and the curved frame structure is replaced by a curved plate-like structure or a curved block-like structure, which is the same in technical effect), so long as the concave-convex curved fixing frames 48 and/or the inner fixing frame 48B can be matched with each other to leave enough seam heads at the edges thereof. For example, the fixing frame can be set to be a concave-convex curved surface similar to the human trunk surface (a curved surface structure similar to three-dimensional cutting is made), and the garment manufactured at one time can be more close-fitting and attractive without affecting the size and shape of the seam. That is, although the first material layer 53 and the second material layer 54 of the left upper machine of the head mount 24 in fig. 42 are plain cloth without being cut, if the fixing frame 48 provided at the lower side or the right side of the head mount 24 in fig. 42 is not a plain structure but a curved surface structure which is mutually engageable up and down, the plain cloth fed from the left side of the head mount 24 in fig. 42 can be naturally fixed as a curved cloth by the curved fixing frame; moreover, due to the tight fixation of the fixing frames, the concave-convex curved surfaces in the fixing frames do not affect all the seam heads outside the fixing frames 48; the seam heads can still be kept on a plane for the integrated machine head to process each procedure. Of course, if the stitching heads at the outer edge of the fixing frame 48 are not distributed on a plane but on a curved surface, the stitching heads distributed in a curved or curved manner in a three-dimensional space can be handled as an integrated machine head under the control of a computer as well because the integrated mechanism can be lifted and lowered and tilted. Even if the budget allows, the multi-axis mechanical arm can be used to replace the machine head mounting frame 24, and the mechanical arm can be used to operate the integrated machine head 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 is realized.

In addition, if the opening diameter of the collar 32 is too small, the head portion cannot be extended, so that the cutting head 20 may cut a vertical incision (as a fly or a half fly) at the collar 32, and may be provided with a fly zipper or velcro at the same time as the above embodiments. If the cuffs of other clothes are too small in opening, sleeve opening is needed for the condition of affecting the four limbs to enter and exit, and similar treatment can be performed. For simplicity, the description and drawings of the specification do not detail such improvements as would be apparent to one skilled in the art.

The underwear vest, the gauze ball coat, the advertisement waistcoat and the like with huge demand can be manufactured by the method and the equipment in the invention quickly, efficiently and at low cost. The method is particularly suitable for products such as gauze ball clothes, advertisement waistcoat and the like which need to continuously adjust the stock quantity and make quick response along with the progress of the match and the elimination of the team.

Compared with the company such as the United states SEWBO and the like which needs to harden the sewn material and set a large number of sensing, shooting, comparing, calculating and/or controlling devices, the method and the device are simpler, more reliable and lower in cost. Of course, various suitable sensors, photographing, comparing, calculating and/or controlling devices may be installed on the apparatus described in the present embodiment to achieve a faster and better production effect, but because the first material layer 53 and the second material layer 54 in the present embodiment are cut simultaneously, complex and tedious cutting, feeding, positioning, aligning and other processes can be avoided, and the same product is made with simpler apparatus and lower cost, and the progress is obvious.

Example 23

In addition to the sleeping bags or garments described in the embodiments above, the present invention may also be applied to the production of single layer products such as mats (e.g., picnic mats) and blankets (e.g., polar fleece blankets) that do not require zippers. That is, it can be implemented on a quilting machine: after the raw material coiled material of the cushion or blanket is put on a machine, the working procedures of cutting, edge wrapping, hemming or trimming, even up to a cloth mark, up to a handle/tab and the like are finished at one time by the equipment of the invention, the cushion or blanket finished product to be packaged is discharged by the machine without separate blanking and sewing and manual intervention, and the production efficiency and the cost are more competitive. Specifically:

After the single-ply raw material roll 61 of the cushion or blanket is set up as shown in fig. 55, the processes of cutting, taping, hemming or overlocking, even up to the upper cloth mark, lifting handle/tab and the like are finished once by the equipment of the invention in the form of 'manual zero intervention' under the control of a computer, and the cushion or blanket finished product to be packaged is discharged by the machine without additional blanking and sewing. Fig. 55 shows a case where the finished product is a hemming structure 57 by the head hemmer 60 of the head 14. The hemming structure 13 can be produced by the apparatus by changing the execution head of the hemming head 14 shown in fig. 55 to the hemming cylinder 17; the hemming structure 34 can be produced by the apparatus as long as the performing head of the hemming head 14 is replaced with the hemming cylinder 39. It follows that by simply changing the execution head of the banding head 14 to the serger 60, the hemming drum 17 and/or the hemming drum 39, the respective serging structure 57, the hemming structure 13 and/or the hemming structure 34 can be obtained.

FIG. 22 shows the apparatus of the present invention when processing three or more layers of material, such as sleeping bags and cold wear; FIG. 42 shows the apparatus of the present invention when handling a double layer material such as a vest, waistcoat, etc.; fig. 55 shows the apparatus of the present invention when processing a single layer of material such as a mat, blanket, etc.

Example 24

Figures 45 and 46 illustrate one embodiment of a one-piece infant sleeping bag of the present invention.

Wherein, the positions of the cut-off openings of the neckline 32 and the armholes 33 are hemming structures 34, and the positions of the cut-off openings of the other side edges and the 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 unfolded and flatly laid on the ground, a table top, a bed surface, a sofa or other planes to be used as a cushion, a quilt or the like; can also be used as a small blanket to wrap the infant. When the zipper 12 is closed as shown in fig. 46, it is a conventional infant sleeping bag.

The neckline 32 of the infant sleeping bag shown in fig. 45 is a semicircle having the same front-rear size and shape after being folded as shown in fig. 46, and such a structure may not be well suited for the human neck (because the neck is easily pulled). Therefore, as long as the neckline 32 is moved downward by a proper distance from the geometric center of the developed view as a whole on the developed view as shown in fig. 45, an ergonomic neckline of "front low and rear high" can be obtained; the neckline 32 shown in fig. 45 can be made into various shapes which are symmetric left and right but asymmetric up and down, such as inverted drop shape, pear shape and/or spindle shape, and the neckline which is low at the front and high at the rear and/or wide at the front and narrow at the rear and meets the ergonomics can be obtained after folding; there are many implementation methods.

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

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

Example 25

Fig. 47 and 48 show one piece cold-proof waistcoat embodiments of the present invention.

Wherein the collar 32, armholes 33 and the lower hem 58 are arranged in a hemming structure 34, and the side edges (armpits) of the waistcoat body 35 are provided with a zipper 12 and a hemming structure 13. When the cold-proof waistcoat is unfolded as shown in fig. 47, the cold-proof waistcoat can be flatly and unfolded and can be flatly and unfolded on the ground, a tabletop, a bed surface or a sofa and other planes to be used as a cushion or a quilt and the like. When the zipper 12 is closed, as shown in fig. 48, it is a piece of cold-proof waistcoat which is worn under the garment.

The cold-proof waistcoat can be fully automatically and efficiently produced on the equipment of the invention, so the price is much better than that of the original waistcoat basically sewn by hands.

Example 26

Fig. 49 and 50 show one embodiment of a one-piece cold protective cotton garment of the present invention.

The collar 32, the cuffs 59 and the hem 58 of the cotton-padded clothes are provided with a hemming structure 34, and the two sides of the cotton-padded clothes body 36 and the sleeves 37 are provided with a zipper 12 and a hemming structure 13. When the cold-proof cotton clothes are unfolded, the cold-proof cotton clothes can be flatly and unfolded and flatly spread on the ground, a table top, a bed surface or a sofa and other planes as shown in fig. 49, 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 piece of ordinary cold-proof cotton clothes.

The hemming structure 13 outside each zipper 12 of the cotton clothes can be made into a weather strip as described in embodiment 4, and the collar 32, the cuff 59 and the hem 58 can be made into a collar or a hem flap as described in embodiment 4, so that the cold-proof effect can be better.

The label 10 shown in fig. 49 and 50 is transported to the hemming structure 13 while the slide fastener 12 is transported during sewing, and the label 10, the slide fastener 12, and the hemming structure 13 are sewn at one time. The layout principle and the arrangement of the label 10 and the zipper 12 are not very different, and the following is not the case: the label 10 is arranged intermittently, and only when the label arranging device is operated to a preset position, the label 10 with a preset size is operated and conveyed out and clamped at the edge wrapping structure 13; the arrangement means of the slide fastener 12 is to continuously (or in a stepwise manner continuously) arrange the slide fastener 12 to the specified respective positions. Whether the zipper layout device or the label layout device, when the positions and the lengths of the laid zippers or labels are suitable, the cutting device on the layout device 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 zippers or the labels are moved to the next preset position.

The cold-proof cotton clothes can be fully automatically and efficiently produced on the equipment of the invention, so the price is much better than that of the original cotton clothes basically sewn by hands.

Example 27

The infant sleeping bag of example 24 may also be made in two pieces for ease of carrying and/or use. As shown in fig. 51 and 52, the original one-piece infant sleeping bag may be broken at the shoulder portion thereof, and a zipper 12 or velcro of an appropriate length may be attached thereto. When the zipper is used after being manufactured, the corresponding zippers 12 or nylon buckles on the two pieces are connected.

Each piece of the infant sleeping bag can be used as a seat cushion and a cover, and can be fully automatically and efficiently produced on the equipment of the invention, so the cost is cheaper than the original cost of the infant sleeping bag which is basically sewn by manual operation.

Example 28

The infant sleeping bags of examples 24 and 27 were of a bag-like structure.

If the fabric is replaced by a single layer, the neckline 32 and/or the armholes 33 are completely or partially omitted, the simple bag is obtained.

The simple bags with adjustable volume can be obtained by arranging a plurality of groups of zippers which divide the space in the bags in parallel. The simple bag is particularly suitable for being used as an outer bag of the sleeping bag, and when the strength of a consumer is relatively high (such as young and young men) and the sleeping bag can be rolled tightly during storage, a bag storage mode with a small storage space can be selected, so that the sleeping bag is convenient to carry and store; when the consumer has smaller force (such as old, weak, sick and disabled or children) and sends the rolls when the sleeping bag is stored, the storage mode of the bag with larger containing space can be selected, so that the problem that the original bag of the sleeping bag manufacturer often causes the consumer to feel difficult to roll back to a common pain point (because the manufacturer saves materials and freight, and the automatic rolling machine of the sleeping bag equipped by the manufacturer can roll the roll to a small size far exceeding that of the common consumer under the drive of a motor, even if the manufacturer leaves loose margin, the margin is generally smaller).

The zipper and/or the label can be arranged at the proper position of the bag structures, and the pull tab, the brace and/or the handle can be arranged in the same way, so that the bag with the pull tab, the brace and/or the handle can be manufactured. These pull tabs, straps and/or handles do not have to be routed along the cut-out, but instead, if desired, directly onto the inner body of the body blank 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 waterproof, the opened bag body can be even used as a backdrop and the like. The multifunctional outdoor bicycle 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 portability 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 velcro of an appropriate length is attached. When in use, the zippers or the nylon buckles of the two waistcoat are connected.

The zipper or the nylon fastener tape can be replaced by a common mode such as a male buckle, a female buckle, a pull rope, a pull belt and a pull piece. For example, the male and female buttons may be attached in an automated manner by an automated dotter at programmed predetermined locations and intervals, etc. The automatic clamping pull rope or pull tab and the like can be completely the same as the automatic label clamping equipment and method in the invention. Of course, the fastener dispensing machine head, the pull cord machine head, and/or the tab machine head, etc. may also be integrated into an integrated machine head instead of, in addition to, or in combination with the zipper dispenser, if desired. Even the male and female buttons are not needed, but the simple buttons are used, and the button is not needed to change one group of button-setting devices into button-opening devices, which is a popular technology in the clothing field and is not needed to be described repeatedly.

Each piece of the cold-proof waistcoat can be produced in a full-automatic mode and high efficiency on the equipment, so the price is much better than that of the original waistcoat basically sewn by hands.

The two-piece or multi-piece structure can be more suitable for modularized production with higher efficiency, each piece of die is respectively and automatically sewn into assemblies in large quantities, and the two or more pieces are combined to obtain a final finished product. The sheets can be completely and mutually independently disassembled, so that the cleaning, airing, replacement and the like are easier. Especially for infant sleeping bags or clothes, which are easy to be polluted by infant water, urine or feces, milk stain and the like.

The two-piece or multi-piece structure has the advantages that the two or more pieces can be selected to have the same shape or size, and the two or more pieces can be selected to have different sizes for combination (but the connecting parts can be completely matched to ensure proper and beautiful connection). For example, if it is desired that the neckline 32 of the infant sleeping bag, waistcoat, vest, cotton-padded clothes, etc. is made to have different heights or widths, the two or more pieces before and after the combination are selected to have different shapes and sizes, so long as the zipper or velcro can be ensured to be properly and aesthetically connected.

Example 30

In some cases, multiple processes such as cutting, quilting, embroidery, taping, punching, etc. may be performed simultaneously, and thus, multiple sets of the integrated heads and/or other functional devices described in the present invention may also be provided on the same main frame. Fig. 23 shows a sleeping bag manufacturing apparatus according to the present invention, in which a gantry crane (inverted U-shaped structure) and a cantilever crane (or a turning bar) are combined. The devices of the different integrated heads and/or the single-function heads under the hanging beams with different positions and different structures can simultaneously, synchronously or respectively play respective functions under the control of a computer, 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 blank 11 during quilting, hemming, serging and/or hemming operations, a rigid frame or form may be pressed over the body blank without affecting these operations, in addition to the suction and securing of the large number of air holes provided in the table in the previous embodiments. Such templates or press frames are a very well established and common method in the template technology that has already been popular (rigid frames or fixed templates are not shown in fig. 23 in order to avoid too complex graphics).

In addition, the cold-proof door curtain or cold-proof curtain which is hung on a door frame or a window in winter in the north of China can also be manufactured by the method and the equipment of the invention. The traditional cold-proof door curtain or the cold-proof curtain needs to be manually sealed because a cold-proof filling layer is required to be placed between the front layer fabric and the rear layer fabric; the method and the device can realize full-automatic sewing without any manual intervention in the middle. The material is put in, and the curtain or the cold-proof door curtain is put out. Even though the zipper routing device of the present invention is not used in such embodiments, it is a considerable advancement in the manufacture of such unzipped products.

The cloth brush 50 of the present invention is not the only part that can be used with the crimping plate 51, and other modes such as blowing crimping (i.e. using air flow blowing in different directions to replace cloth brush rotating in different directions) or mechanical clamping crimping are also possible to be used with the crimping plate 51, and the proper selection should be made according to specific process, material, quality, environmental requirements, etc.

The term "body" as used herein refers not only to the body of the finished sleeping bag, garment, bag, blanket, and mat, but also to the semi-finished products that make up or constitute these finished products. For example, one of the two-piece finished products of the above embodiments 27 and 29, or one of the complex structures such as clothing having a plurality of pieces, may also be regarded as a "body". That is, the "body primary product" referred to in the present invention includes not only "sleeping bag body primary product", "vest body primary product", "waistcoat body primary product", "blanket body primary product" but also "tile body primary product" or "component body primary product", etc., but also "body finished product" referred to in the present invention includes not only "sleeping bag body finished product", "vest body finished product", "waistcoat body finished product", "blanket body finished product" but also "tile body finished product" and "component body finished product", etc.

When a sewing product with a plurality of pieces is manufactured, different low-cost assembly lines can be set up for different pieces to respectively manufacture different pieces; the finished products of different splice bodies manufactured through different pipelines are converged on the assembly line through a manipulator and other devices, and the assembly line can also use various splicing methods and equipment shown in the embodiment of the invention to realize that the method and equipment can be utilized to stitch a sewing product with a complex structure of a plurality of splice pieces in a way of 'one side of the pipeline is provided with various materials, and the other side of the pipeline is provided with finished products in a manual zero intervention' way.

In order to improve the production efficiency, the main frame can be prolonged or enlarged to have enough space for a plurality of groups of body primary products which are arranged horizontally, vertically or horizontally and vertically, and the plurality of groups of body primary products are processed simultaneously, so that the production efficiency can be improved by times. Under the condition that the conveying time of the sewn material is not considered, the production efficiency is improved to be nearly twice as high as that of the original two-piece sewing machine, the production efficiency is improved to be nearly three times as high as that of the original three-piece sewing machine, and the production efficiency is improved to be nearly four times as high as that of the original four-piece sewing machine. For products with smaller sizes such as waistcoats, vests and the like, because a plurality of primary products of the main body can be arranged on the main frame, the production efficiency of the products can be improved by tens of times or even tens of times.

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

The term "at least" as used herein includes the present number.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant points refer to the description of the method section.
