Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a transverse neckline cutting device. Background Technology

[0002] In the textile industry, collar cutting machines are essential equipment for garment production. Their main function is to cut the raw material according to the pattern of the garment, thereby cutting out a collar that matches the pattern of the garment. The collar is then sewn together with the main body of the garment to complete the garment processing and production.

[0003] The collar cutting machine mentioned in the above process, in the existing technology,

[0004] 1. Firstly, it is usually a semi-automatic operation, which requires staff to load the material. During the loading process, the blank needs to be positioned. In the existing technology, the positioning structure for the collar is usually a template. The template is expensive to use, and it is easy to deform after long-term use, causing errors in the positioning of the blank. Moreover, the longer it is used, the greater the error becomes, and new templates need to be replaced regularly, which is very costly.

[0005] 2. Secondly, after the collar cutting machine cuts the fabric, the finished collar fabric and the cut scraps cannot be separated. They are both placed at the discharge port of the collar cutting machine, requiring manual sorting of the finished collar fabric and scraps. Moreover, the sorted finished collar fabric is relatively scattered, which is inconvenient for subsequent processing of the finished collar fabric.

[0006] In summary, those skilled in the art have proposed a transverse collar cutting device that uses laser positioning and automatically separates and sorts finished collar fabric. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a transverse collar cutting device, which solves the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a transverse collar cutting device, comprising:

[0009] The cabinet has an infeed area at the top front and an outfeed area at the top rear.

[0010] A collar conveying module, which is fixedly installed inside the cabinet and can work intermittently, is used to convey uncut collars and cut collars.

[0011] The blank placement table, located above the feeding area, is used to place uncut collars;

[0012] At least three laser positioners are provided, and the laser beams all fall on the material feeding area, but at different positions, to accurately position the uncut collar.

[0013] The collar cutting module is located on the conveying path of the collar conveying module and is used to cut the collar.

[0014] The unloading module is located on the conveying path of the collar conveying module and behind the collar cutting module. It is used to unload the cut collar into the discharge area.

[0015] The receiving module, located in the discharge area, is used to catch the collar carried by the unloading module and arrange it neatly.

[0016] Furthermore, pre-drilled holes are provided on both sides of the discharge area, and the two ends of the receiving module extend outward from the cabinet through the pre-drilled holes. Top cover one and top cover two are respectively installed on the top of the cabinet. The collar cutting module and the unloading module are respectively installed inside the top of top cover one and top cover two. In the discharge area, the area in front of the receiving module is set as the waste material discharge area.

[0017] Furthermore, the collar conveying module includes a bracket installed inside the cabinet, a tension adjuster installed inside the bracket, a drive sprocket assembly installed between the tension adjusters, a first sprocket installed in a section of the drive sprocket assembly, a drive motor installed at the top of the bracket, and a second sprocket installed at the drive end of the drive motor, with the first sprocket and the second sprocket being driven by a chain.

[0018] Furthermore, driven sprocket sets are installed at both the front and rear ends of the bracket. The driven sprocket sets and the driving sprocket sets are arranged in a triangular pattern. The driving sprocket sets and the driven sprocket sets are driven by a chain. Several conveyor plates are installed on the outer end face of the chain. The spacing between each conveyor plate is the same, and the conveyor plates are components that can undergo elastic deformation.

[0019] Furthermore, each conveyor plate has a positioning strip connected to the middle of its upper surface, and the uppermost conveyor plate conveys collar fabric. The lasers emitted by the three laser positioners all fall on each conveyor plate passing through the feeding area.

[0020] Furthermore, the collar cutting module includes a collar cutting cylinder installed at the top of an inner part of the top cover and guide rods located on both sides of the collar cutting cylinder. The bottom end of the guide rod is connected to a cutter mounting base. The drive end of the collar cutting cylinder is connected to the cutter mounting base. A cutter mounting sub-base is installed inside the cutter mounting base. A cutter is installed at the bottom end of the cutter mounting sub-base. The cutter has an arc-shaped structure and can cut off the arc-shaped collar shape. The blade of the cutter protrudes from the cutter mounting base.

[0021] Furthermore, the unloading module includes a base frame installed at the top of the inner part of the top cover. An unloading push cylinder is installed on the side of the base frame. A guide rail is installed at the bottom of the base frame. A crossbeam is slidably connected below the guide rail. The telescopic end of the unloading push cylinder is connected to the crossbeam through a linkage. Pick-up cylinders are installed at both ends of the crossbeam. A gripper cylinder is installed at the telescopic end of the pick-up cylinder.

[0022] Furthermore, the receiving module includes an interception mechanism installed inside the cabinet and a receiving mechanism installed inside the discharge area.

[0023] Furthermore, the interception mechanism includes a base installed at the bottom of the cabinet. A second drive motor is installed at the center of the top of the base, and limit cylinders are installed on both sides of the top of the base. A return spring is installed inside the limit cylinder, and a pressure rod is movably connected above the return spring inside the limit cylinder. The pressure rod abuts against the return spring. A cam is installed at the drive end of the second drive motor. A pressure plate is connected to the top of the pressure rod. The cam abuts against the center of the pressure plate. An interception plate one and an interception plate two are respectively connected to the two ends of the pressure plate. An interception slot is opened at the top of both the first and second interception plates.

[0024] Furthermore, the receiving mechanism includes a receiving box installed inside the discharge area. The end face of the receiving box has a track that slopes from one end to the other. Several rollers are rolled inside the track. Each roller has a limiting groove on its surface that engages with the upper and lower sides of the track. Each roller is rotatably connected to a receiving rod through a bearing.

[0025] This invention provides a device for horizontally cutting collars. Compared with the prior art, it has the following advantages:

[0026] 1. This transverse collar cutting device uses several laser positioners, each emitting a laser beam that lands on the material feeding area at a different location. This allows for accurate positioning of the uncut collar, replacing the templates used in existing technologies for positioning the blank. It is designed to eliminate errors even after prolonged use and significantly reduces costs compared to templates.

[0027] 2. This horizontal neckline cutting equipment can automatically separate neckline fabric and scraps. By adding a receiving module to the discharge area of ​​the neckline cutting machine, the receiving module can collect each piece of cut neckline fabric. After collection, it is convenient for workers to pick up the materials at one time. The collected neckline fabric is neat and orderly, not scattered, which is convenient for subsequent processing and use of neckline fabric. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 , 23. This invention provides a technical solution: a transverse collar cutting device, including a cabinet 1, a collar conveying module 2, a blank placement platform 3, a laser positioner 4, a collar cutting module 5, a material unloading module 6, and a material receiving module 7. Specifically, the top of the front end of the cabinet 1 is provided with an inlet area 11, and the top of the rear end is provided with an outlet area 12. The collar conveying module 2 is fixedly installed inside the cabinet 1 and can work intermittently to convey uncut collars and cut collars. The blank placement platform 3 is located above the inlet area 11 and is used to place uncut collars. At least three laser positioners 4 are provided, and the laser beams all fall on the feeding area 11, but at different positions, to accurately position the uncut collar. The collar cutting module 5 is located on the conveying path of the collar conveying module 2 and is used to cut the collar. The unloading module 6 is located on the conveying path of the collar conveying module 2 and is located behind the collar cutting module 5. It is used to unload the cut collar to the discharge area 12. The receiving module 7 is located in the discharge area 12 and is used to catch the collar carried by the unloading module 6 and arrange them neatly.

[0045] Please see Figure 1 , 2 13, 2, 3, 13, both sides of the discharge area 12 are provided with reserved holes 13, and both ends of the receiving module 7 extend to the outside of the cabinet 1 through the reserved holes 13. The top of the cabinet 1 is respectively equipped with top cover 14 and top cover 2 15. The cutting module 5 and the unloading module 6 are respectively installed inside the top of top cover 14 and top cover 2 15. In the discharge area 12, the area in front of the receiving module 7 is set as the waste material dropping area 16.

[0046] Please see Figure 4 The collar conveying module 2 includes a bracket 21 installed inside the cabinet 1. Tension adjusters 22 are installed inside the bracket 21. A drive sprocket assembly 23 is installed between the tension adjusters 22. A first sprocket 24 is installed in a section of the drive sprocket assembly 23. A drive motor 25 is installed at the top of the bracket 21. A second sprocket 26 is installed at the drive end of the drive motor 25. The first sprocket 24 and the second sprocket 26 are driven by a chain. Driven sprocket assemblies 27 are installed at both the front and rear ends of the bracket 21. The drive sprocket assembly 23 is triangularly distributed. The drive sprocket assembly 23 and the driven sprocket assembly 27 are driven by a chain 28. Several conveyor plates 29 are installed on the outer end face of the chain 28. The spacing between each conveyor plate 29 is the same, and the conveyor plate 29 is a component capable of elastic deformation. A positioning strip 210 is connected to the middle of the upper surface of each conveyor plate 29. The uppermost conveyor plate 29 conveys the collar fabric 8. The lasers emitted by the three laser positioners 4 are all located on each conveyor plate 29 passing through the feeding area 11 (as shown in the attached diagram). Figure 14 Points a, b, and c in the diagram represent the laser landing points of the three laser positioners 4.

[0047] When the neckline conveying module 2 is working, the drive motor 25 can work intermittently as needed, so that the entire neckline conveying module 2 can work intermittently. The drive motor 25 drives the second sprocket 26 to rotate, and the second sprocket 26 drives the first sprocket 24 to rotate through the chain, thereby driving the drive sprocket group 23 to rotate. Under the action of the two driven sprocket groups 27, the drive sprocket group 23 drives the chain 28 to rotate, which in turn drives several conveyor plates 29 to move synchronously, thereby driving the neckline fabric 8 to move.

[0048] Please see Figure 5 , 6 7. The collar cutting module 5 includes a collar cutting cylinder 51 installed at the top of the top of the top cover 14 and guide rods 52 located on both sides of the collar cutting cylinder 51. The bottom end of the guide rods 52 is connected to a cutter mounting base 53. The drive end of the collar cutting cylinder 51 is connected to the cutter mounting base 53. A cutter mounting sub-base 54 is installed inside the cutter mounting base 53. A cutter 55 is installed at the bottom end of the cutter mounting sub-base 54. The cutter 55 has an arc-shaped structure and can cut off the arc-shaped collar shape. The blade of the cutter 55 protrudes from the cutter mounting base 53.

[0049] When the collar cutting module 5 is working, the collar cutting cylinder 51 extends and retracts, which sequentially drives the cutter mounting base 53, the cutter mounting base 54, and the cutter 55 to move up and down. When it moves down to the lowest point, the blade of the cutter 55 will contact the edge of the collar fabric 8, thereby achieving one-time cutting of the collar shape.

[0050] Please see Figure 8 , 9 The unloading module 6 includes a base frame 61 installed at the top of the inside of the top cover 15. An unloading push cylinder 62 is installed on the side of the base frame 61. A guide rail 63 is installed at the bottom of the base frame 61. A crossbeam 64 is slidably connected below the guide rail 63. The telescopic end of the unloading push cylinder 62 is connected to the crossbeam 64 through a linkage 65. Pick-up cylinders 66 are installed at both ends of the crossbeam 64. A gripper cylinder 67 is installed at the telescopic end of the pick-up cylinder 66.

[0051] When the unloading module 6 is working, the picking cylinder 66 extends, pushing the gripper cylinder 67 downward. When the gripper cylinder 67 can hold the cut neckline fabric 8, the gripper cylinder 67 grips it. After gripping, the picking cylinder 66 shortens, causing the gripper cylinder 67 and the neckline fabric 8 to move upward synchronously. At this time, the unloading push cylinder 62 extends, pushing the crossbeam 64 to move along the guide rail 63 towards the discharge area 12. When the neckline fabric 8 reaches above the receiving module 7, the gripper cylinder 67 releases the neckline fabric 8, allowing the neckline fabric 8 to fall onto the receiving module 7.

[0052] Please see Figure 10 The receiving module 7 includes an interception mechanism 71 installed inside the cabinet 1 and a receiving mechanism 72 installed inside the discharge area 12.

[0053] Please see Figure 11 The interception mechanism 71 includes a base 711 installed at the bottom of the cabinet 1. A second drive motor 712 is installed at the middle of the top of the base 711. Limiting cylinders 713 are installed on both sides of the top of the base 711. A return spring 714 is installed inside the limiting cylinder 713. A pressure rod 716 is movably connected inside the limiting cylinder 713 above the return spring 714. The pressure rod 716 abuts against the return spring 714. A cam 715 is installed at the drive end of the second drive motor 712. A pressure plate 717 is connected to the top of the pressure rod 716. The cam 715 abuts against the middle of the pressure plate 717. An interception plate 718 and an interception plate 719 are connected to the two ends of the pressure plate 717, respectively. An interception slot 7110 is opened at the top of the interception plate 718 and the interception plate 719.

[0054] Please see Figure 12 The receiving mechanism 72 includes a receiving box 721 installed inside the discharge area 12. The end face of the receiving box 721 has a track 722. The track 722 is inclined from one end to the other end. Several rollers 723 are rolled inside the track 722. Each roller 723 has a limiting groove 7231 on its surface that engages with the upper and lower sides of the track 722. Each roller 723 is rotatably connected to a receiving rod 724 through a bearing.

[0055] In operation, at the beginning, all the receiving rods 724 of the receiving module 7 are located at the left end of the receiving box 721 (within the left end of the receiving box 721). Figure 12 Taking the perspective of [example] as an example, when material collection is required, drive motor 712 drives cam 715 to rotate 360°. During the rotation, cam 715 has a most prominent point. When this most prominent point passes through pressure plate 717, it will exert downward pressure on pressure plate 717, causing pressure plate 717 to move down. At the same time, pressure rod 716 presses down on return spring 714, causing return spring 714 to store force. After pressure plate 717 moves down, it will synchronously drive interceptor plate 718 and interceptor plate 719 to move down, so that roller 723 is no longer engaged with interceptor slot 7110. At this time, the two receiving rods 724, which are no longer resisted by interceptor plate 718 and interceptor plate 719 (the receiving rod 724 corresponding to interceptor plate 718 has not yet received material, while the receiving rod 724 corresponding to interceptor plate 719 has already received material, status attached). Figure 12As shown), it will move along the inclined direction of the runway 722. The receiving rod 724 corresponding to the second interceptor plate 719 carries the collar fabric 8 to the right end of the receiving box 721. After the receiving rod 724 corresponding to the first interceptor plate 718 passes the first interceptor plate 718, the first interceptor plate 718 will move upward (moving upward because the most convex point of the cam 715 can no longer apply downward pressure to the pressure plate 717 as the cam 715 rotates, under the action of the return spring 715). When the pressure plate 717 rises, it intercepts the next receiving rod 724. The receiving rod 724 that has already passed the first intercepting plate 718 will be intercepted by the second intercepting plate 719, which rises synchronously with the first intercepting plate 718. It is located in the middle of the feeding module 6. The feeding module 6 releases the neck fabric 8, and the neck fabric 8 will fall accurately on the receiving rod 724, with both ends hanging down naturally in a "U" shape. This process is repeated to complete the neat collection of multiple neck fabrics 8.

[0056] In this transverse neckline cutting device, the neckline conveying module 2 operates intermittently. It pauses when one of the conveyor plates 29 is inside the feeding area 11. At this time, the worker takes an uncut neckline fabric 8 from the blank placement table 3 and places it on the conveyor plate 29. During placement, it is important to note that all three laser positioners 4 will display three crosshair cursors on the conveyor plate 29, as shown in the attached diagram. Figure 14 As shown, when placing the neckline fabric 8, the upper left corner of the neckline fabric 8 needs to coincide with the center point (point a) of the left "+" shaped cursor, the lower right vertical edge needs to coincide with the vertical line of the right "+" shaped cursor (point b), and the middle part of the neckline fabric 8 needs to coincide with the center point of the middle "+" shaped cursor (point c). Only in this way can the standard shape and size of the neckline fabric 8 be cut out.

[0057] After the neckline fabric 8 is placed, the neckline conveying module 2 starts working, moving the neckline fabric 8 to a stop below the collar cutting cylinder 51. The collar cutting cylinder 51 cuts the neckline fabric 8. The cut neckline fabric 8 and the waste material continue to move with the neckline conveying module 2 to the picking area of ​​the unloading module 6. The unloading module 6 picks up the cut neckline fabric 8 (but does not pick up the cut waste material, which continues to move with the neckline conveying module 2 and falls into the waste material dropping area 16), and pushes it above the receiving module 7. After the unloading module 6 releases the neckline fabric 8, it will fall onto the receiving module 7, and the receiving module 7 can neatly collect and arrange the neckline fabric 8.
