Description

Technical Field

[0001] This invention relates to the field of garment production equipment technology, and in particular to an automatic feeding device for garment production. Background Technology

[0002] Zippers are an important component in garment manufacturing. They not only provide convenience for opening and closing clothing but can also become decorative elements in garment design. Due to industrial development, the garment industry is trending towards streamlined, modular, and step-by-step processing and production. In the zipper sewing module of automated garment processing equipment, a robotic arm picks up the zipper and then places it in the corresponding sewing position on the garment for zipper sewing.

[0003] Zippers undergo a smoothness test on a sample of zippers before leaving the factory, but it cannot be guaranteed that every zipper will meet the smoothness requirements. In the garment production process, zippers are usually sewn directly into the garment, which will result in some jamming zippers being used in the finished garment, affecting the quality of the garment. Summary of the Invention

[0004] This invention proposes an automatic feeding device for garment production to avoid the use of jammed zippers in finished garments. The device is specifically designed for feeding zippers and detects the smoothness of the zipper during the feeding process to ensure that smooth zippers are used in finished garments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeding device for garment production, used for feeding zippers, includes a base, a material bin for holding zippers, and a material conveyor belt for conveying zippers. The feeding channel of the material bin's outlet extends above the material conveyor belt. Above the material conveyor belt, in the zipper conveying direction, a vision detector for detecting the zipper's orientation, a flipping component for flipping the zipper, and a detection component for detecting zipper smoothness are sequentially arranged.

[0007] The aforementioned detection assembly includes a support body, two upper limit plates for limiting the upper part of the fabric strips on both sides of the zipper, two lower limit plates for limiting the lower part of the fabric strips, and a chuck for gripping the protrusion on the zipper head. The chuck is located between the two upper limit plates and between the two lower limit plates. The upper limit plates are movably connected to the support body in a first horizontal direction, and the lower limit plates are movably connected to the support body in both the first horizontal and vertical directions. A second pickup plate for picking up the fabric strip is provided at the bottom of the upper limit plates. The chuck is movably connected to the clamping seat in the vertical direction, and the clamping seat is movably connected to the support body in a second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction, and the first horizontal direction is parallel to the conveying direction of the zipper.

[0008] Preferably, the upper limit plate is connected to the support body via a first cylinder whose axis is set in the first horizontal direction. The lower limit plate is fixedly connected to one end of a third cylinder, the other end of which is connected to a connecting rod. The connecting rod is fixedly connected to the lower end of a second cylinder, and the upper end of the second cylinder is fixedly connected to the support body. The axis of the second cylinder is vertically set, and the axis of the third cylinder is parallel to the first horizontal direction. The chuck is connected to a clamping seat via a clamping cylinder whose axis is vertically set. The clamping seat is connected to the support body via a pulling cylinder, the axis of which is parallel to the second horizontal direction.

[0009] Preferably, the automatic feeding device further includes a detection conveying bracket for conveying the detection components. The detection conveying bracket is provided with a first closed annular slide rail arranged horizontally. Multiple second feeding seats are provided inside the first closed annular slide rail and are slidably connected to the first closed annular slide rail. The second feeding seats are fixedly connected to the mounting seat, and the mounting seat is connected to the support body through a second pickup cylinder.

[0010] Preferably, the flipping assembly includes a picking conveyor belt for picking up the zipper to be flipped and flipping the zipper, and a dispensing conveyor bracket for placing the flipped zipper back onto the material conveyor belt. The picking conveyor belt has multiple evenly distributed first picking plates, each first picking plate being connected to the picking conveyor belt via a corresponding first picking cylinder. The dispensing conveyor bracket is located above the picking conveyor belt and has a second closed annular slide rail arranged horizontally. Inside the second closed annular slide rail are multiple evenly distributed first feeding seats that are slidably connected to the second closed annular slide rail. Each first feeding seat has a dispensing plate for picking up the zipper, and the dispensing plate is connected to the first feeding seat via a dispensing cylinder.

[0011] The flipping action of the flipping assembly includes the following process: after the first pickup plate picks up the zipper to be flipped, it moves from the lower conveyor surface of the pickup conveyor belt to the upper conveyor surface to realize the flipping of the zipper. The discharge plate takes the zipper from the first pickup plate on the upper conveyor surface of the conveyor belt and sends the zipper to the return material conveyor belt.

[0012] The beneficial effects of this invention are:

[0013] 1. This automatic feeding device for garment production is used for feeding zippers. The automatic feeding device is equipped with a detection component. Before the zipper is used for sewing the garment, the detection component can detect the smoothness of the zipper and remove any non-smooth zippers in time to ensure the smoothness of the zippers used on the garment and maintain the quality of the garment.

[0014] 2. The detection components of this automatic feeding device for garment production are not only used to detect the smoothness of the zipper, but also to open or close the zipper according to the sewing condition of the zipper, so that the whole zipper or two strips of fabric can be obtained during the feeding process, which is suitable for different sewing conditions.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] The automatic feeding device for garment production in this embodiment is used for feeding zippers during garment production. (Refer to...) Figure 1 This automatic feeding device includes a base 1, on which a material box 4 for holding zippers and a material conveyor belt 2 for conveying zippers are provided. The discharge port of the material box 4 is connected to one end of the feeding channel 41, and the other end of the feeding channel 41 extends above the material conveyor belt 2. The feeding channel 41 is used to send the zippers 3 discharged from the material box 4 to the material conveyor belt 2 for feeding the zippers 3.

[0031] Furthermore, above the material conveyor belt 2, in the zipper conveying direction, a vision detector 10, a flipping component, a detection component 8, and a feeding cylinder 9 are sequentially arranged. The vision detector 10 is used to detect the placement direction of the zipper, the flipping component is used to flip the zipper, the detection component 8 is used to detect the smoothness of the zipper, and the feeding cylinder 9 is used to feed the zipper.

[0032] Specifically, the vision detector 10 is an industrial camera used to detect the orientation of the zipper 3. (Reference) Figure 8 The zipper 3 includes two fabric strips 31, with multiple linearly arranged teeth 32 fixedly disposed on the edges of the fabric strips 31. The teeth 32 are used to engage the fabric strips 31, and the zipper head 33 is used to separate and engage the teeth 32 on the two fabric strips 31. Generally, the zipper head 33 has a protrusion 34, which is used to install a pull ring for easy pulling. In this embodiment, the side of the zipper head 33 with the protrusion 34 facing upwards is the target zipper orientation; if the side of the zipper head 33 with the protrusion 34 facing downwards, it is a zipper to be flipped.

[0033] refer to Figure 1 and Figure 2The flipping assembly includes a pick-up conveyor belt 5 and a discharge conveyor bracket 6, with the discharge conveyor bracket 6 located above the pick-up conveyor belt 5. The pick-up conveyor belt 5 is used to pick up the zipper to be flipped and to flip the zipper, while the discharge conveyor bracket 6 is used to place the flipped zipper back onto the conveyor surface of the material conveyor belt 2.

[0034] The aforementioned pickup conveyor belt 5 is provided with multiple evenly distributed first pickup plates 51, each of which is a negative pressure suction cup. Each first pickup plate 51 is connected to the pickup conveyor belt 5 via a corresponding first pickup cylinder 52. The first pickup cylinder 52 is used to drive the first pickup plate 51 to move vertically, thereby enabling the first pickup plate 51 to move closer to or further away from the conveying surface of the material conveyor belt 2.

[0035] refer to Figure 2 and Figure 3 The aforementioned material feeding conveyor bracket 6 is equipped with a second closed-loop slide rail arranged horizontally, parallel to the XZ plane. Multiple evenly distributed first feeding seats 63 are arranged inside the second closed-loop slide rail, and the first feeding seats 63 are slidably connected to the second closed-loop slide rail. A first drive conveyor belt is provided at the top of the material feeding conveyor bracket 6, and the multiple first feeding seats 63 are evenly distributed on the first drive conveyor belt. The conveying path of the first drive conveyor belt matches the second closed-loop slide rail. The first drive conveyor belt can move simultaneously with multiple first feeding seats 63, and the conveying speed of the first drive conveyor belt is the same as the conveying speed of the pick-up conveyor belt 5 and the return material conveyor belt 2.

[0036] A discharge plate 61 is provided on the first feeding seat 63. The discharge plate 61 is a negative pressure suction cup used to pick up the zipper on the first pickup plate 51. The discharge plate 61 is connected to the first feeding seat 63 through a discharge cylinder 62. The discharge cylinder 62 is used to drive the discharge plate 61 to move vertically, so that the discharge plate 61 moves closer to or further away from the first pickup plate 51 and the conveying surface of the material conveyor belt 2.

[0037] The rear end of the material feeding conveyor 6 is located behind the rear end of the pickup conveyor belt 5, so that the rear end of the material feeding conveyor 6 is not blocked by the pickup conveyor belt 5, giving the material feeding plate 61 space to send the zipper to the conveying surface of the material conveyor belt 2.

[0038] During the flipping process of the above-mentioned flipping assembly, when the detector 10 detects that the material conveyor belt 2 has a zipper 3 to be flipped, the first pickup plate 51 of the lower conveying surface of the pickup conveyor belt 5 moves downward to pick up the zipper 3 to be flipped. The pickup conveyor belt 5 moves the zipper 3 from the lower conveying surface of the pickup conveyor belt 5 to the upper conveying surface, so that the side with the protrusion 34 on the zipper 3's pull head 33 faces upward, thus achieving flipping. The discharge plate 61 takes the flipped zipper 3 from the first pickup plate 51 of the upper conveying surface of the pickup conveyor belt 5, and the discharge plate 61 moves behind the pickup conveyor belt 5 to send the zipper back to the conveying surface of the material conveyor belt 2.

[0039] refer to Figure 1 , Figure 4 and Figure 9 Multiple detection components 8 are mounted on a detection conveyor bracket 7, which is used to convey these components. The detection conveyor bracket 7 is fixedly connected to the base 1. It features a first closed-loop slide rail arranged horizontally, parallel to the XZ plane. Multiple evenly distributed second feeding seats 71 are arranged inside the first closed-loop slide rail, and these seats are slidably connected to it. A second drive conveyor belt is positioned at the top of the detection conveyor bracket 7, with the second feeding seats 71 evenly distributed on it. The conveying path of the second drive conveyor belt matches the first closed-loop slide rail. The second drive conveyor belt can move simultaneously with the multiple second feeding seats 71, and its conveying speed is the same as that of the return material conveyor belt 2.

[0040] The detection component 8 includes a support body 810, a second feeding seat 71 fixedly connected to a mounting seat 72, and the mounting seat 72 connected to the support body 810 via a second pickup cylinder 73. The second pickup cylinder 73 is used to drive the support body 810 to move in the vertical direction.

[0041] refer to Figure 5 and Figure 6 The support body 810 is provided with two upper limit plates 81, two lower limit plates 83, and a chuck 84. The chuck 84 is located between the two upper limit plates 81 and the two lower limit plates 83. The upper limit plates 81 are used to limit the upper part of the fabric strips 31 on both sides of the zipper 3, and the lower limit plates 83 are used to limit the lower part of the fabric strips 31 on both sides of the zipper 3. The bottom of the chuck 84 is provided with claws 85. The chuck 84 is a double claw chuck. The chuck 84 is used to grab the protrusion 34 on the upper part of the zipper head 33 and move the protrusion 34 along the extension direction of the zipper 3 to realize the opening and closing of the zipper 3.

[0042] Specifically, the upper limit plate 81 is movably connected to the support body 810 in the first horizontal direction. The top of the upper limit plate 81 is connected to the support body 810 via a first cylinder 89. The axis of the first cylinder 89 is set in the first horizontal direction (X-axis), and the first cylinder 89 is used to drive the upper limit plate 81 to move in the first horizontal direction. A second pickup plate 82 is set at the bottom of the upper limit plate 81. The second pickup plate 82 is a negative pressure suction cup, and the second pickup plate 82 is used to pick up the fabric strip 31. The aforementioned first horizontal X-axis is parallel to the conveying direction of the zipper.

[0043] The lower limit plate 83 and the support body 810 are movably connected in the first horizontal direction (X-axis) and the vertical direction (Y-axis), respectively. Specifically, the lower limit plate 83 is fixedly connected to one end of the third cylinder 832, and the other end of the third cylinder 832 is connected to the connecting rod 833. The connecting rod 833 is fixedly connected to the lower end of the second cylinder 831, and the upper end of the second cylinder 831 is fixedly connected to the support body 810. The axis of the second cylinder 831 is vertical (Y-axis), and the axis of the third cylinder 832 is parallel to the first horizontal direction (X-axis). The second cylinder 831 and the third cylinder 832 respectively drive the lower limit plate 83 to move, so that the lower limit plate 83 can move below the fabric strip 31 to support the lower part of the fabric strip 31.

[0044] Furthermore, the support body 810 is equipped with a clamping seat 87 and a pulling cylinder 88. The clamping seat 87 is movably connected to the support body 810 in the second horizontal direction (Z-axis), and the pulling cylinder 88 is connected to the clamping seat 87. The pulling cylinder 88 is used to drive the clamping seat 87 to move along the Z-axis in the second horizontal direction. A tension sensor is installed on the pulling cylinder 88 to detect the tension of pulling the zipper 3, thereby detecting the smoothness of the zipper 3. When the tension is greater than a set value, it is determined that the zipper 3 is not smooth; when the tension is less than the set value, it is determined that the zipper 3 is smooth.

[0045] The chuck 84 is connected to the clamping seat 87 via a clamping cylinder 86 that is vertically set along the axis. The clamping cylinder 86 is used to drive the chuck 84 to move in the vertical direction (Y-axis).

[0046] refer to Figure 4 and Figure 9 The inspection and conveying support 7 is equipped with a picking station 701, a positioning station 702, an inspection station 703, a feeding station 704, and a rejection station 705. The picking station 701, positioning station 702, inspection station 703, and feeding station 704 are all located above the conveying surface of the material conveyor belt 2. The rejection station 705 is not located above the conveying surface of the material conveyor belt 2. A box for defective materials is set below the rejection station 705. The detection component 8 picks up the zipper 3 at the picking station 701; it sets the upper and lower limits on the fabric strip 31 of the zipper 3 at the positioning station 702; the detection station 703 is located between the positioning station 702 and the feeding station 704, and it performs a pulling test on the zipper head 33 of the zipper 3 at the detection station 703; at the feeding station 704, it sends the smooth zipper to the conveying surface of the material conveyor belt 2; at the rejection station 705, it sends the non-smooth zipper 3 to the unqualified material box.

[0047] The machine base 1 is equipped with a rotary table 92, which is rotatably connected to the machine base 1. The upper part of the rotary table 92 is connected to the feeding cylinder 9 via a connecting rod. The lower part of the feeding cylinder 9 is equipped with a third pickup plate 91, which is a negative pressure suction cup. The third pickup plate 91 is used to pick up the zipper 3 on the conveying surface of the material conveyor belt 2 and to send the zipper 3 to the designated sewing position for feeding the zipper 3.

[0048] The working process of the automatic feeding device for garment production in this embodiment is as follows:

[0049] Step 1: Zipper 3 exits from the discharge port of material box 4, passes through the feeding channel 41 and arrives at the conveying surface of material conveyor belt 2, and material conveyor belt 2 conveys zipper 3.

[0050] Step 2: Zipper 3 passes through visual detector 10, which detects the orientation of zipper 3.

[0051] When the side of the zipper pull 33 with the protrusion 34 is facing down, the zipper 3 needs to be flipped over and proceed to step three; when the side of the zipper pull 33 with the protrusion 34 is facing up, it does not need to be flipped over and proceed to step four.

[0052] Step 3: When the zipper 3 to be flipped passes the pickup conveyor belt 5, refer to... Figure 2 The first pickup plate 51 on the lower conveyor surface of the pickup conveyor belt 5 moves downward to pick up the zipper 3 to be flipped. The pickup conveyor belt 5 moves the zipper 3 from the lower conveyor surface to the upper conveyor surface, so that the side with the protrusion 34 on the upper pull head 33 of the zipper 3 faces upward, thus achieving flipping.

[0053] The feeding plate 61 takes the flipped zipper 3 from the first picking plate 51 on the conveying surface of the picking conveyor belt 5, and the feeding plate 61 moves to the rear of the picking conveyor belt 5 to send the zipper to the conveying surface of the return material conveyor belt 2.

[0054] Step 4: Zipper 3 leaves the flipping assembly and enters the area below the detection conveyor bracket 7. When zipper 3 arrives at the picking station 701, the second picking cylinder 73 of the detection assembly 8 extends, the support body 810 and the upper limit plate 81 move downward, and the two second picking plates 82 simultaneously adsorb and pick up the two strips 31 of zipper 3. The second picking cylinder 73 shortens, and zipper 3 leaves the conveying surface of the material conveyor belt 2.

[0055] refer to Figure 7 The detection component 8 moves to the positioning station 702, and the second cylinder 831 and the third cylinder 832 drive the lower limit plate 83 to move, so that the lower limit plate 83 can move to the bottom of the cloth strip 31 to support the lower part of the cloth strip 31.

[0056] refer to Figure 8 The detection component 8 moves to the detection station 703, the clamping cylinder 86 drives the chuck 84 to move, the chuck 84 clamps the protrusion 34 on the upper part of the zipper head 33, and the pulling cylinder 88 moves the clamping seat 87, the chuck 84 and the zipper head 33 back and forth in the second horizontal direction (Z axis) to detect the smoothness of the zipper.

[0057] After the test is completed, the chuck 84 releases its grip on the zipper head 33, the clamping cylinder 86 resets, the lower limit plate 83 releases its restriction on the lower part of the fabric strip 31, and the smooth zipper 3 enters step five and then step six.

[0058] Step 5: The detection component 8 moves to the feeding station 704, the second picking cylinder 73 extends, the support body 810 and the upper limit plate 81 move downward, the two second picking plates 82 release the adsorption on the upper part of the cloth strip 31, the zipper 3 returns to the conveying surface of the material conveyor belt 2, and proceeds to step 7.

[0059] Step 6: The detection component 8 moves to the rejection station 705, the second pick-up cylinder 73 extends, the support body 810 and the upper limit plate 81 move downward, the two second pick-up plates 82 release the adsorption on the upper part of the cloth strip 31, and the zipper 3 enters the non-conforming material box.

[0060] Step 7: The third pickup plate 91 picks up the zipper 3, and the rotating table 92 carries the zipper 3 to the designated sewing position to complete the feeding of the zipper.

[0061] It is worth noting that after the smoothness of the zipper 3 is tested in step four, the zipper 3 can remain either in a separated or closed state between the two fabric strips 31. When the zipper 3 of the garment is sewn in a closed state, the two fabric strips 31 of the zipper 3 remain in a closed state after the test is completed. When the zipper 3 of the garment is sewn in a separated state, the two fabric strips 31 of the zipper 3 remain in a separated state after the test is completed.

[0062] When the two strips 31 of zipper 3 need to be closed, refer to Figure 11 After the test is completed, the pull cylinder 88 moves the pull head 33 to the first end 301 of the cloth strip 31, at which point the pull teeth 32 of the two cloth strips 31 are fully engaged.

[0063] When the two strips 31 of zipper 3 need to be pulled apart, refer to Figure 12 After the test is completed, the pulling cylinder 88, with the pulling head 33, is positioned at the second end 302 of the fabric strip 31. At this time, the pulling teeth 32 of the two fabric strips 31 are not engaged. Then, the lower limit plate of the first fabric strip with the pulling head 33 is slightly loosened, and the pulling cylinder 88 continues to move the pulling head 33 away from the first end of the fabric strip 31, causing the first fabric strip with the pulling head 33 to separate from the second fabric strip without the pulling head 33, thus separating the two fabric strips. After the two fabric strips are separated, the lower limit plate 83 of the corresponding fabric strips is released. When the two fabric strips are sent to the conveying surface of the material conveyor belt 2, the adsorption of the second pickup plate 82 corresponding to the fabric strips 31 is released one after the other. The material conveyor belt 2 can move with the fabric strip 31 that has been released first, forming a gap between the two fabric strips 31, which facilitates the separate pickup by the third pickup plate 91.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
