[0049] In order to solve the problem that the processing quality of shoulder loops is difficult to ensure in the related art, refer to Figure 1 An embodiment of the present application provides a shoulder loop sewing device, comprising a workbench 100, a folding auxiliary device arranged on the workbench 100, a sewing device 300, a transfer device 400 and a control device 700, wherein the folding auxiliary device is used to mark the folding position of the fabric to be folded to obtain the fabric to be sewn 600, wherein the fabric to be sewn 600 comprises a surface piece and a bottom piece; the sewing device 300 is used to sew the fabric to be sewn 600; the transfer device 400 is used to transfer the fabric to be sewn 600 at the folding auxiliary device to the sewing device 300, and press the fabric to be sewn 600 while the fabric to be sewn 600 is being sewn; the control device 700 is connected to the folding auxiliary device, the sewing device 300 and the transfer device 400, and the control device 700 is used to control the operating states of the folding auxiliary device, the sewing device 300 and the transfer device 400 according to the preset size information of the shoulder loop.

[0050] Among them, the four corners of the bottom wall of the workbench 100 are rotatably connected with universal wheels 140, so that the worker can move the shoulder loop stitching device according to the processing requirements later, and the bottom wall of the workbench 100 is also threadedly connected with a support seat 150, so as to realize the positioning of the workbench 100 after moving. The control device 700 is a terminal device electrically connected to the folding auxiliary device, the sewing device 300, and the transfer device 400. The control device 700 includes a device body and a touch screen arranged on the device body. A feeding part 500 is also provided on the side of the workbench 100 close to the auxiliary device. The feeding part 500 includes a feeding box, which is fixedly connected to one side of the workbench 100. The feeding box contains neatly arranged fabrics to be folded. In order to facilitate the control device 700 to accurately control the operating status of the folding auxiliary device, the sewing device 300 and the transfer device 400 according to the size information of the shoulder loop, the fabrics to be folded in the feeding box are fabrics for processing the same batch of fabrics with the same size of shoulder loops.

[0051] Specifically, the worker first inputs the size information of the shoulder loop to be processed into the control device 700 through the touch screen, so that the control device 700 adaptively adjusts the operating states of the folding auxiliary device, the sewing device 300, and the transfer device 400 according to the size information of the shoulder loop, so as to determine the folding position of the fabric, adjust the sewing speed and method, adjust the transfer trajectory, etc.; then the fabric to be folded is placed on the folding auxiliary device, and the folding auxiliary device automatically marks the position where the fabric to be folded needs to be placed to assist manual folding to obtain the fabric to be sewn 600; the transfer device 400 transfers the fabric to be sewn 600 to the sewing device 300 for sewing, and while sewing, the transfer device 400 will stably press and hold the fabric to be sewn 600 to ensure the stability of the sewing process.

[0052] In this embodiment, the control device 700 is used to control the folding auxiliary device according to the preset size information of the shoulder loop to accurately determine the placement position of the fabric to be folded, so that the part that needs to be folded can be accurately determined, and the control device 700 is used to control the transfer device 400 to transfer the folded fabric to be sewn 600 to the sewing device 300 for automatic sewing, and while the fabric to be sewn 600 is being sewn, the transfer device 400 is used to stably press and hold the folded fabric, which helps to ensure the sewing effect of the shoulder loop, and then ensure the processing quality of the shoulder loop; and it helps to reduce manual operations and improve the processing efficiency of the shoulder loop.

[0053] Reference Figure 1In some embodiments, a frame 110 is further provided on the workbench 100, and the folding auxiliary device includes a positioning portion 210, a laser positioning assembly 220 and a limiting assembly 230. The positioning portion 210 is used to receive the cloth to be folded, and the positioning portion 210 is provided with a positioning portion 212 for assisting the folding of the cloth to be folded; the laser positioning assembly 220 is arranged on the frame 110, and the laser positioning assembly 220 is located above the positioning portion 210. The laser positioning assembly 220 is used to emit a positioning laser to the positioning portion 210 for marking the placement position of the cloth to be folded; the limiting assembly 230 is used to limit the cloth to be folded on the positioning portion 210.

[0054] The positioning portion 210 is a specific area on the workbench 100 for loading materials. The cloth to be folded is placed on the positioning portion 210 in the initial state. The side portion 212 is a long strip-shaped protrusion located on one side of the positioning portion 210. The laser positioning component 220 is located above the positioning portion 210. The laser positioning component 220 is a device that uses infrared lasers for auxiliary positioning. The laser positioning component 220 is installed on the frame 110. The laser positioning component 220 can adjust the laser emission position according to the preset size information of the shoulder loop. Since the cloth to be folded has good softness, after folding, in order to enable the subsequent transfer device 400 to stably transfer the cloth, it must be fixed by the limit component 230.

[0055] Specifically, after the fabric to be folded is received on the positioning portion 210, the limiting component 230 first positions the fabric to be folded according to the preset size information of the shoulder loop, and at the same time, the laser positioning component 220 emits an infrared laser to the positioning portion 210. The position where the infrared laser falls on the fabric to be folded is the position of the crease when the fabric to be folded is folded. For example, the laser emitted by the laser positioning component 220 can simultaneously mark the placement positions of three sides of the fabric to be folded, so that the worker can determine the position of the remaining side that needs to be folded. After determining the folding position of the fabric, the worker folds the side of the fabric to be folded close to the folding position along the positioning portion 212 to obtain the fabric to be sewn 600. At this time, the transfer device 400 starts to operate, and at the same time, the limiting component 230 releases the fabric to be sewn 600, so that the transfer device 400 transfers the fabric to be sewn 600 to the sewing device 300.

[0056] In this embodiment, the cooperation of the laser positioning component 220 and the limiting component 230 helps to ensure the stability and accuracy of the workers when folding the cloth. Before the transfer device 400 transfers the cloth to be sewn 600, the limiting component 230 helps to maintain the flatness of the cloth to be sewn 600, thereby helping to ensure the smoothness of the subsequent transfer device 400 when transferring the cloth to be sewn 600.

[0057] Reference Figure 1In some embodiments, a plurality of air holes are provided on the positioning portion 210, and the limiting assembly 230 includes a suction fan 232, a suction switching component 234 and a suction channel arranged under the workbench 100, the suction channel is connected to the plurality of air holes, the suction fan 232 is connected to the suction channel, and the suction switching component 234 is used to control the connection between the suction channel and the suction fan 232.

[0058] The bottom of the workbench 100 is hollowed out to accommodate the suction fan 232 and the suction switching member 234. The suction switching member 234 is a control device 700 that can control the start and stop of the fan. In addition, there can be two suction channels in this embodiment, the suction port of one suction channel is connected to a plurality of air holes, and the suction port of the other suction channel is connected to the outside world, and the ends of the two suction channels away from their own suction ports are connected to the suction fan 232; the suction switching member 234 is used to control the connection and disconnection between the suction channel and the suction fan 232, so as to achieve the limitation and release of the cloth placed on the positioning part 210.

[0059] Specifically, the suction fan 232 can be in a working state all the time. When the cloth to be folded is placed on the positioning portion 210, the suction switching member 234 controls the suction channel connected to the air hole to be connected to the suction fan 232, so that the suction fan 232 exhausts air at the positioning portion 210, thereby making the cloth to be folded flatly adsorbed on the positioning portion 210; after the worker determines the folding position of the cloth to be folded according to the infrared laser line and folds the cloth to be folded, the suction fan 232 is still exhausting air, and when the transfer device 400 presses the folded cloth, the suction switching member 234 controls the suction fan 232 to be connected to the suction channel of another suction port connected to the outside world, so that there is no suction at the positioning portion 210, thereby facilitating the transfer device 400 to smoothly transfer the cloth to be sewn 600 to the sewing device 300 against the upper surface of the workbench 100.

[0060] In this embodiment, through the cooperation of the suction fan 232, the suction switching member 234 and the two suction channels, the stable adsorption and release of the cloth can be achieved, and the flatness of the cloth can be ensured before and after the cloth is folded, and it helps to ensure the smoothness of the subsequent transfer device 400 when transferring the cloth to be sewn 600.

[0063] Specifically, after the transfer device 400 transfers the fabric 600 to be sewn to the sewing device 300, the sewing device 300 cuts and sews the fabric 600. When the sewing of the fabric 600 is completed, the cutting is also completed, which helps to further improve the processing efficiency of the shoulder loops.

[0064] In this embodiment, through the cooperation of the sewing needle 320, the cutting piece 330 and the transfer device 400, the automated sewing operation of the shoulder loop while cutting and sewing is realized, thereby reducing manual operations, improving the processing efficiency of the shoulder loop, and helping to ensure the sewing effect and processing quality of the shoulder loop.
