Detailed Description
The present invention will be described more fully hereinafter in order to facilitate an understanding of the present invention. Preferred embodiments of this invention are presented herein. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items. As used herein, "multiple" includes two and more items. As used herein, "above a certain number" should be understood to mean a certain number and a range of numbers greater than a certain number.
Compared with the prior art that the collar tie is split by adopting a mode of mechanically simulating manual wire drawing by a machine, the invention develops a new way and adopts another technical conception to split the collar tie.
Specifically, according to one embodiment of the present invention, an automated collar removal method includes the steps of:
the method comprises the steps of obtaining a collar workpiece to be disassembled, wherein the collar workpiece to be disassembled comprises a strip-shaped connecting part and collar piece parts which are respectively connected to two sides of the connecting part along the length direction of the connecting part, and the light transmittance of the connecting part is different from that of the collar piece parts;
identifying the position of the connecting part according to the difference of the light transmittance of the connecting part and the collar piece part;
and ablating the identified positions of the connecting parts by adopting laser, and removing the connecting parts.
The collar piece part in the workpiece to be detached comprises a collar piece, and the collar piece is to be understood in a broad sense, and is not limited to a collar used at the neck of clothes, but can be cuffs used for sleeves or a hem of clothes and other textile components with similar structures to the collar.
It is understood that the collar piece may be a flat collar with a fold line structure. The flat collar with the fold line structure refers to a flat collar with a fold line, and the flat collar with the fold line structure is generally used for round collars, cuffs, lower hem and other positions. Wherein the fold line structure refers to: a folding line is added at the transverse central position of the flat collar, and the folding line can be woven by two rows of unilateral weaves. The flat collar with the fold line structure needs to be folded in the middle when in use, and is sewn on the clothes after double layers are overlapped. The purpose of knitting the broken line is that can be convenient for turn over in the middle along the position of broken line when sewing, avoid because the difference of turning over the position leads to the difference in the height that the finished product collar exposes. The flat collar with the fold line structure has the biggest characteristics that in the actual use process, the collar piece is folded in the middle, and both sides of the collar piece are required to be sewn on clothes, namely, the flat collar with the fold line structure is required to be sewn on both sides. The two sides of the collar piece after laser ablation are in a scattered state, and the two sides of the collar piece are required to be sewn by the flat machine collar with the broken line structure, so that the subsequent sewing process is not influenced even if the two sides of the collar piece are in the scattered state.
Further, in one specific example, the length of the connection is greater than or equal to 60cm. The traditional mechanical wire drawing method is not suitable for splitting the connecting part with the length more than or equal to 60cm, and the laser ablation mode in the invention can be applied to splitting the longer collar piece part because the wire positioned in the middle is not required to be drawn.
The light transmittance refers to the ratio of the luminous flux transmitted to the other side after the light irradiates to one side of the collar piece or the connecting part to the luminous flux before transmission, and the lower the light transmittance of the fabric is, the stronger the shading capability is. For fabrics, the light transmittance is affected by factors such as the weave pattern of the fabric and the thickness and material of the yarns, for example, the thinner the yarns of the fabric, the thinner the fabric itself, the higher the light transmittance of the fabric. Alternatively, the looser the weave pattern of the fabric, the lower the weave density, and the higher the light transmittance of the fabric. The difference of light transmittance between the collar piece and the connecting part can be obtained by adopting a specific weaving method when the workpiece to be collar detached is prepared.
The laser has better focusing property, can focus on one point on the fabric, and can instantly raise the temperature of the point to ablate and remove the fabric at the point. The laser ablation method is adopted, so that the connecting part can be removed with extremely high efficiency, the collar sheets on two sides of the connecting part can be removed by ablation, and the completeness of the collar sheets is maintained.
In the traditional technology, a mechanical collar removing method is adopted, only the imitation and reproduction of the manual collar removing process are performed, and the machine is difficult to be flexible like manual work, so that the quality problem is difficult to be avoided. In the embodiment, the method of determining the position through light transmittance and removing the connecting part by laser ablation is obviously different from the method of extracting the silk thread in the traditional technology in conception, the whole process can complete the detachment of a plurality of collar sheets without the operations of removing stitches or cleaning and the like, the detachment is rapid, and the collar detachment efficiency can be effectively improved.
Referring to fig. 1, a specific structure diagram of a workpiece 100 to be collar removed includes a connecting portion 110 and a collar segment portion 120, the workpiece 100 to be collar removed includes a strip-shaped connecting portion 110 and a plurality of collar segment portions 120, and collar segment portions 120 are disposed on two sides of the connecting portion 110. Referring to fig. 1, the workpiece to be collar removed includes a plurality of connecting portions 110 and a plurality of collar segments 120 alternately arranged, and collar segments 120 are disposed on both sides of each connecting portion 110.
The method of identifying the position of the connection portion 110 based on the difference in light transmittance between the connection portion 110 and the neck piece portion 120 refers to identifying the connection portion 110 by utilizing the property of the difference in light transmittance. By identifying the connection portion 110 by the light transmittance difference, the specific position of the connection portion 110 can be accurately identified without affecting the connection portion 110 and the collar segment 120, and preparation is made for the subsequent laser ablation step. In one specific example, the step of identifying the position of the connection portion 110 is specifically: light is applied to one surface of the workpiece 100 to be collar-removed, and the intensity of the transmitted light is detected on the other surface of the workpiece 100 to be collar-removed, so as to identify the position of the connecting portion 110.
Further, in one more specific example, the collar segments 120 on the workpiece 100 to be collar-removed may be spread integrally, and the light source is used to uniformly irradiate the surface of one side of the workpiece 100 to be collar-removed, and the vision lens 212 is disposed on the surface of the other side to detect the light flux passing through the workpiece 100 to be collar-removed, and the light fluxes of different positions detected by the vision lens 212 are different due to the different light transmittances of the collar segments 120 and the connecting portion 110 in the workpiece 100 to be collar-removed, so that the vision lens 212 can distinguish the specific position of the connecting portion 110.
After vision lens 212 has resolved the particular location of connection 110, the identified location of connection 110 may be ablated with a laser to remove connection 110. In one specific example, the material of the connection portion 110 is cotton, for example, the material of the connection portion 110 may be selected from 100% combed cotton. Compared with the polyester material of the common fish silk thread, the cotton yarn after laser ablation has smooth edge and no burrs, does not influence the subsequent sewing step, does not need manual cleaning, and can greatly improve the efficiency of collar disassembly. On the other hand, if terylene is adopted, black solid adhered in an aggregation shape remains after laser ablation, and the terylene can be used only by manual subsequent cleaning, so that the collar disassembly efficiency is reduced.
In one specific example, the transmittance of the connection portion 110 is higher than that of the collar portion 120, and if the transmittance of the connection portion 110 is higher, the connection portion 110 in the vision lens 212 is in a high-light state, which is more beneficial for the resolution of the connection portion 110 by the vision lens 212.
Further, when the transmittance of the connection portion 110 is made higher than that of the collar portion 120, the fabric density of the connection portion 110 is further set to be also lower than that of the collar portion 120. Alternatively, the density of the connecting portion 110 in the length direction is lower than the fabric density of the neck piece portion 120 in the length direction. In one specific example, the yarn length of the connecting portion 110 is relaxed by 50 c=15 mm to 25mm compared to the yarn length of the neck piece portion 120, where the yarn length refers to a 50C yarn length. It can be understood that, if the weaving density of the connection portion 110 is lower, the connection portion 110 is looser and thinner than the collar segment 120, so that the light transmittance of the connection portion 110 can be effectively improved.
In a more specific example, the yarn length of the connection portion 110 is relaxed by 50c=15 mm, 18mm, 21mm, 25mm, or a range between the above dimensions as compared to the yarn length of the neck piece portion 120. The specific yarn length of the connection portion 110 and the neck piece portion 120 may be set as follows. The yarn length 50C of the collar portion 120 is 205mm to 210mm, and the yarn length 50C of the connecting portion 110 is 225mm to 230mm.
In order to realize continuous mass production of the collar segment 120 during weaving, a plurality of collar segment 120 are sewn together, and the collar segment 120 is split into individual collar segments 120 after the production is completed. In order to improve the splitting efficiency, the prior art generally adopts a mode of extracting the middle connecting wire to split the collar, in order to ensure the strength of the thread to facilitate extraction, a fish thread is generally adopted to stitch, and in order to further ensure that the coil of the collar segment 120 is not affected in the thread extraction process, the adjacent collar segment 120 is generally stitched together by adopting a locking weave mode.
One of the conventional locking weave methods is to weave a row of rib yarns first, weave two front single sides and one rear single side, weave a row of rib yarns with a fish thread and weave one rear single side with a fish thread. The main purposes of this locking weave are as follows: the collar segments 120 on two sides can be tightly sewn together, the problem of broken collar in the production process is avoided, meanwhile, the fish threads in the collar segments can be pulled out under the condition that the main body coil on the collar segments 120 is not affected, and the rapid separation of the collar segments 120 on two sides of the fish threads is realized. The rib weave is one of the basic weave of weft knitting fabrics, and is formed by combining front side wales and back side wales in a certain form.
However, the above-mentioned locking weave method is mainly used to satisfy the requirement of removing the fish thread, and most of the time, it is not suitable for the connection 110 which is loose and thinner than the collar portion 120, and is also not suitable for the subsequent laser ablation step, so that in one embodiment of the present invention, a connection 110 suitable for an automated collar removing method is also provided. In one specific example, the connecting portion 110 includes two yarns sewn to the neck piece portion 120 in a rib weave. Specifically, two yarns in the connection portion 110 are respectively sewn with the collar piece portions 120 on both sides of the connection portion 110. This special knitting method is to knit and stitch the neck piece portion 120 and the neck piece portion 120 with two patterns of cotton yarn instead of the fish thread, and can ensure the loosening and thinness of the connecting portion 110 as much as possible while ensuring the strength so as not to be broken in the production process.
In one specific example, the number of yarns of the connection portion 110 is less than the number of yarns of the neck piece portion 120, for example, the number of yarns of the connection portion 110 is 2 and the number of yarns of the neck piece portion 120 is 3.
Further, the invention also provides an automatic collar removing device for realizing the automatic collar removing method, which comprises a light transmittance identification mechanism, a laser source 220 and a controller. The light transmittance identifying mechanism is used for identifying the connecting portion 110 in the workpiece 100 to be disassembled according to the difference of light transmittance, the laser source 220 is used for emitting laser capable of ablating yarns of the connecting portion 110, and the controller is electrically connected to the light transmittance identifying mechanism and the laser source 220 and used for obtaining the specific position of the connecting portion 110 identified by the light transmittance identifying mechanism and controlling the laser source 220 to emit laser along the position of the connecting portion 110 so as to ablate the connecting portion 110.
Specifically, referring to fig. 2, an automated collar removal device includes a light transmittance identification mechanism, a laser source 220, and a controller (not shown in fig. 2).
Further, the light transmittance identifying mechanism comprises a backlight 211 and a visual lens 212, the backlight 211 can move, the backlight 211 is used for emitting light, the visual lens 212 is used for receiving the light emitted by the backlight 211, a working station and a avoiding station are arranged on the moving path of the backlight 211, and the visual lens 212 and the backlight 211 are electrically connected to the controller. The automatic collar removing device further comprises a conveyor belt 230, wherein a conveying path of the conveyor belt 230 passes through between the vision lens 212 and the backlight 211 at the working station. The main purpose of the movable backlight 211 is to enable the backlight 211 to avoid the laser emitted by the laser source 220, so as to avoid damage to the backlight 211.
In one specific example, the automated collar assembly further includes a laser barrier 240, the laser barrier 240 being configured to block laser light after passing through the connection 110 to avoid laser ablation of other components.
Referring to fig. 3, the above-described automatic collar remover may operate as follows.
Step S1, a specific position of the connection portion 110 is identified.
Specifically, the workpiece 100 to be disassembled may be disposed on the conveyor belt 230, the backlight source 211 is disposed at the working station and emits light toward the vision lens 212, when the workpiece 100 to be disassembled is disposed between the backlight source 211 and the vision lens 212, the light emitted by the backlight source 211 is blocked, and since the transmittance of the connecting portion 110 in the workpiece 100 to be disassembled is different from that of the collar segment 120, the vision lens 212 receives light with two kinds of brightness respectively representing different areas, and then the vision lens 212 can distinguish the area where the connecting portion 110 is located in combination with the transmittance specifically set in the workpiece 100 to be disassembled.
In step S2, the backlight 211 is moved to the avoidance station, and the laser shutter 240 for blocking the laser is exposed.
Specifically, the backlight 211 may be electrically connected to a controller, and after the controller receives the specific position of the connection portion 110 measured by the vision lens 212, the controller controls the backlight 211 to move to the avoidance station, so as to avoid the scanning path of the subsequent laser and expose the laser baffle 240 located below the avoidance station.
Step S3, the laser is used to ablate the identified position of the connection portion 110, and the connection portion 110 is removed.
Specifically, after the controller receives the information fed back by the vision lens 212 and controls the backlight 211 to move to the avoidance station, the controller may control the laser to move along the specific position of the connection portion 110 detected by the vision lens 212, so as to remove the connection portion 110. The laser light transmitted through the connection portion 110 can be blocked by the laser shutter 240.
Fig. 4 shows a schematic perspective view of the laser ablation process of fig. 3. Referring to fig. 4, the laser source 220 is moved from one end of the connection portion 110 to the other end, during which the laser is scanned across the connection portion 110 along the length of the connection portion 110, ablating the connection portion 110 to remove the connection portion 110. For a workpiece 100 to be collar-removed that includes multiple links 110, after ablation of the links 110, the laser source 220 may also be moved back and forth so that the laser source 220 is aligned with the other links 110 and the ablation action described above is repeated.
In order that the invention may be more readily understood and put into practical effect, the following more particular examples and comparative examples are provided as reference. The various embodiments of the present invention and their advantages will also be apparent from the following description of specific examples and comparative examples and performance results.
The raw materials used in the examples below are all commercially available, unless otherwise specified.

Example 2 differs from example 1 mainly in that the connection in example 2 is woven with 150D/2 of fishing line. After laser ablation, the parts of the collar sheets on the two sides, which are close to the connecting parts, remain adhered black solids, and the secondary cleaning is needed manually.
Example 3
Acquiring a workpiece to be collar detached; the workpiece to be disassembled comprises a connecting part and collar sheets positioned at two sides of the connecting part, wherein the collar sheets are flat machine collars with fold line structures; wherein the collar piece is woven in a rib structure mode by using 30S combed cotton, the yarn number is 3, the yarn length 50C is 205-210 mm, the connecting part is woven in a rib structure mode by using 30S combed cotton, the yarn number is 1, and the yarn length 50C is 225-230 mm. The connection part is looser and thinner than the collar piece, so that the transmittance of the connection part is also higher.
The method comprises the steps that a workpiece to be disassembled is flatly paved between a backlight source and a visual lens, the backlight source emits uniform light towards the bottom surface of the workpiece to be disassembled, the visual lens is arranged above the workpiece to be disassembled, the light transmitted through the workpiece to be disassembled is collected, the light transmittance of each part is tested, and the position of a connecting part is fed back to a controller by the visual lens according to the specific position of the connecting part of the light transmittance analysis.
The controller controls the laser to move to a position above a specific position of the connecting part, scans along the position of the connecting part, ablates yarns of the connecting part and separates collar sheets positioned on two sides of the connecting part.
The main difference between example 3 and example 1 is that the connection is made of only one piece of 30S combed cotton. The connecting part prepared in this way is fragile, and is easy to break, so that the collar is easy to disperse, and the ablation treatment is difficult to concentrate.
