Description

[0001] Shoe cutting piece loading and unloading device Technical Field

[0002] This utility model relates to the technical field of shoe cutting equipment, and in particular to a shoe cutting device for loading and unloading. Background Technology

[0003] Traditional shoe production processes, such as die-cutting, hot pressing, sanding, spraying, drying, inspection, and packaging, have long relied on manual loading and unloading of materials. Shoe panels, including the midsole and upper, are also made using manual loading and unloading.

[0004] To automate the feeding of shoe pieces, existing methods use turntables, conveyor belts, and grippers for loading and unloading. However, shoe pieces are inherently flexible, making the gripping accuracy of existing grippers relatively low and prone to deformation. While suction cups can be used, their suction is easily compromised due to the tiny pores in the shoe pieces. Therefore, existing shoe piece feeding devices cannot meet current production needs.

[0005] To solve the above problems, it is necessary to provide a device for loading and unloading shoe pieces. Utility Model Content

[0006] The purpose of this utility model is to provide a feeding and unloading device for shoe pieces, which uses a needle-type material picker to automatically feed and unload shoe pieces, avoiding deformation of shoe pieces and failure of gripping, and has the advantages of good feeding and unloading effect and high accuracy.

[0007] To achieve the above objectives, the shoe cutting piece loading and unloading device provided by this utility model includes a frame, a moving drive mechanism, a material tray, and a needle-type material picker. The material tray is installed on the frame, the moving drive mechanism is installed on the frame, and the needle-type material picker is elastically installed on the output end of the moving drive mechanism. Under the drive of the moving drive mechanism, the needle-type material picker can move up and down and horizontally relative to the frame. The needle-type material picker has a hook. When the needle-type material picker elastically presses against the material tray, the hook of the needle-type material picker can pick up the material by hooking the workpiece on the material tray.

[0008] Preferably, the needle-type material picker includes a material picker head and a hook, the material picker head is elastically mounted on the output end of the moving drive mechanism, and the hook is located on the bottom pressing surface of the material picker head.

[0009] Specifically, the hooks are provided in multiples, and the multiple hooks are arranged at equal intervals on the bottom pressing surface of the material taking head.

[0010] Preferably, the frame is provided with a material picking station, and the moving drive mechanism includes a horizontal moving drive component and a lifting moving drive component. The horizontal moving drive component is installed on the frame, and the lifting moving drive component is installed at the output end of the horizontal moving drive component. The lifting moving drive component moves along the front-back direction of the frame under the drive of the horizontal moving drive component. The needle-type material picking component is elastically installed at the output end of the lifting moving drive component. The needle-type material picking component moves up and down under the drive of the lifting moving drive component, so that the needle-type material picking component moves to the material picking station or exits.

[0011] Preferably, the shoe piece loading and unloading device further includes an elastic connection assembly, which includes an elastic element, a sleeve, and a guide rod. The sleeve is connected to the output end of the moving drive mechanism via a mounting bracket. The guide rod is connected to the needle-type material pick-up component. The guide rod is slidably disposed on the sleeve so that the guide rod and the sleeve can extend and retract relative to each other. The elastic element provides an elastic force that causes the guide rod and the sleeve to always have a tendency to elongate relative to each other.

[0012] Preferably, the shoe cutting piece loading and unloading device further includes a lifting drive device, the frame is provided with a material picking station, the material tray is installed at the output end of the lifting drive device, and the material tray is lifted and lowered under the drive of the lifting drive device so that the material tray moves to the material picking station or exits.

[0013] Specifically, the shoe piece loading and unloading device further includes a guide assembly, which includes a guide rod and a slider. The guide rod is mounted on the frame and arranged along the lifting direction of the material tray. The slider is connected to the material tray and slides on the guide rod.

[0014] Preferably, the material tray has a clearance hole corresponding to the hook of the needle-type material picker.

[0015] Preferably, the shoe cutting piece loading and unloading device further includes a first sensor, which is built into the needle-type material picking component. The first sensor is used to detect whether there is material on the material tray, and the first sensor is electrically connected to the moving drive mechanism.

[0016] Preferably, the shoe cutting piece loading and unloading device further includes a second sensor for sensing the position of the material tray.

[0017] Compared with the prior art, the shoe cutting piece loading and unloading device provided by this utility model features a needle-type material picker. This needle-type material picker is elastically mounted on the output end of a moving drive mechanism. Driven by the moving drive mechanism, the needle-type material picker can move up and down and horizontally relative to the frame. This allows the needle-type material picker to press against or move away from the workpiece on the material tray. The needle-type material picker has hooks; when it elastically presses against the material tray, the hooks can hook onto the workpiece to pick it up. The elastic pressing of the needle-type material picker prevents damage from rigid collisions. Under the premise of hooking the workpiece on the tray, the material is picked up by hooking the workpiece and then moved to the next station. It is understandable that since the workpiece is a shoe piece, the shoe piece itself has ventilation holes, and the hook itself is relatively small, so the hooking action when the hook is pressed down will not affect the pass rate of the workpiece itself, which meets the production requirements. It is precisely this workpiece requirement that makes the needle-type material picking device with hook more suitable for loading and unloading shoe pieces, avoiding the deformation of shoe pieces and gripping failure caused by the gripper, and has the advantages of good loading and unloading effect and high accuracy.

[0024] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please see Figures 1 to 6The shoe cutting piece loading and unloading device 100 of this utility model includes a frame 1, a moving drive mechanism 2, a material tray 3, and a needle-type material picker 4. The material tray 3 is mounted on the frame 1, the moving drive mechanism 2 is mounted on the frame 1, and the needle-type material picker 4 is elastically mounted on the output end of the moving drive mechanism 2. Under the drive of the moving drive mechanism 2, the needle-type material picker 4 can move up and down and horizontally relative to the frame 1, so that the needle-type material picker 4 can press against or move away from the workpiece 20 on the material tray 3. The needle-type material picker 4 has a hook 41. When the needle-type material picker 4 elastically presses against the material tray 3, the hook 41 of the needle-type material picker 4 can pick up the workpiece 20 on the material tray 3 by hooking it. The elasticity of the needle-type material picker 4... The pressing mechanism hooks onto the workpiece 20 on the tray 3 without damaging the needle-type material picker 4 with rigid collisions. This hooking action completes the material picking process, allowing the workpiece to move to the next workstation. It's understandable that since the workpiece 20 is a shoe piece with ventilation holes, and the hook 41 has a relatively small hook size, the hooking action of the hook 41 does not affect the pass rate of the workpiece 20, meeting production requirements. It is precisely these requirements of the workpiece 20 that make the needle-type material picker 4 with the hook 41 more suitable for loading and unloading shoe pieces, avoiding deformation and gripping failure caused by the grippers. This results in better loading and unloading efficiency and higher accuracy. More specifically, as follows:

[0026] Please see Figures 5 to 6 The needle-type material handling component 4 includes a material handling head 42 and a hook 41. The material handling head 42 is elastically mounted on the output end of the moving drive mechanism 2, and the hook 41 is disposed on the bottom pressing surface 421 of the material handling head 42. Preferably, multiple hooks 41 are provided, and the multiple hooks 41 are arranged at equal intervals on the bottom pressing surface 421 of the material handling head 42, thereby making the hooking force more uniform and the material handling more stable.

[0027] Please see Figures 1 to 2 The frame 1 is provided with a material picking station 11. The moving drive mechanism 2 includes a horizontal moving drive component 21 and a lifting moving drive component 22. The horizontal moving drive component 21 is installed on the frame 1, and the lifting moving drive component 22 is installed at the output end of the horizontal moving drive component 21. The lifting moving drive component 22 moves along the front and rear direction of the frame 1 under the drive of the horizontal moving drive component 21. The needle-type material picking component 4 is elastically installed at the output end of the lifting moving drive component 22. The needle-type material picking component 4 is lifted and lowered under the drive of the lifting moving drive component 22, so that the needle-type material picking component 4 moves to the material picking station 11 or exits, and drives the needle-type material picking component 4 to press against the workpiece 20 or retract.

[0028] Please see Figures 1 to 2The shoe cutting piece loading and unloading device 100 also includes an elastic connection component 5. The elastic connection component 5 includes an elastic element 51, a sleeve 52, and a guide rod 53. The sleeve 52 is connected to the output end of the moving drive mechanism 2 through a mounting bracket. The guide rod 53 is connected to the needle-type material take-up component 4. The guide rod 53 is slidably disposed inside the cavity of the sleeve 52 so that the guide rod 53 and the sleeve 52 can extend and retract relative to each other. The elastic element 51 is sleeved outside the guide rod and abuts against the sleeve 52 and the needle-type material take-up component 4. The elastic element 51 provides an elastic force that makes the guide rod 53 and the sleeve 52 always have a tendency to extend relative to each other. The elastic force makes the guide rod 53 always have a tendency to slide in a direction away from the sleeve 52. When the needle-type material take-up component 4 presses against the material tray 3, the guide rod 53 and the sleeve 52 overcome the elastic force of the elastic element 51 and retract relative to each other, thereby achieving the purpose of avoiding rigid collision. When the needle-type feeder 4 moves away from the feed tray 3, the guide rod 53 and the sleeve 52 are reset and relatively elongated under the elastic action of the elastic element 51.

[0029] Please see Figures 4 to 6 The shoe cutting piece loading and unloading device 100 also includes a lifting drive device 7. The frame 1 is provided with a material picking station 11. The material tray 3 is installed at the output end of the lifting drive device 7. The material tray 3 is lifted and lowered under the drive of the lifting drive device 7 so that the material tray 3 moves to the material picking station 11 or exits.

[0030] Please see Figure 4 The shoe cutting piece loading and unloading device 100 also includes a guide assembly 6, which includes a guide rod 61 and a slider 62. The guide rod 61 is installed on the frame 1 and is arranged along the lifting direction of the material tray 3. The slider 62 is connected to the material tray 3 and slides on the guide rod 61. The lifting action of the material tray 3 is made more stable and smooth by the guiding action.

[0031] Please see Figures 1 to 2 The material tray 3 is provided with a clearance hole 31 corresponding to the hook 41 of the needle-type material picker 4. The clearance hole 31 can further avoid rigid collisions of the hook 41, thereby protecting the hook 41. Preferably, multiple clearance holes 31 are provided, and the multiple clearance holes 31 are equally spaced on the material tray 3. In this embodiment, the clearance hole 31 is an elongated hole, but it is not limited to this, and the producer can adjust it according to actual needs.

[0032] Please see Figure 1 as well as Figure 2The shoe cutting piece loading and unloading device 100 also includes a control worktable 10, a first sensor 8, and a second sensor 9. Both the first sensor 8 and the second sensor 9 are electrically connected to the control worktable 10. The first sensor 8 is built into the needle-type material picker 4 and is used to detect whether there is material on the material tray 3. The moving drive mechanism 2 is electrically connected to the control worktable 10, thereby making the first sensor 8 electrically connected to the moving drive mechanism 2. When the first sensor 8 detects that there is material on the material tray 3, the moving drive mechanism 2 drives the needle-type material picker 4 to perform a material picking action. The second sensor 9 is used to sense the position of the material tray 3. The second sensor 9 is set on the frame 1 and located at the material picking station 11. The control worktable 10 is electrically connected to the lifting drive device 7, thereby making the second sensor 9 electrically connected to the control worktable 10. When the second sensor 9 detects the position of the material tray 3 and the position of the workpiece 20 on the material tray 3, that is, the position status of the workpiece 20 and the material tray 3, when they are in position, the lifting drive device 7 stops driving the material tray 3 to rise.

[0033] Please refer to the following: Figures 1 to 6 The working process of the shoe cutting piece loading and unloading device 100 of this utility model is as follows:

[0034] The material tray 3 carrying shoe pieces rises to the material picking station 11 under the drive of the lifting drive device 7. During this process, the second sensor 9 senses the position of the material tray 3. When the second sensor 9 detects the position of the material tray 3 and the position of the workpiece 20 on the material tray 3, that is, the position of the workpiece 20 and the material tray 3, the lifting drive device 7 stops driving the material tray 3 to rise. The first sensor 8 is used to detect whether there is material on the material tray 3. When the first sensor 8 detects that there is material on the material tray 3, the moving drive mechanism 2 drives the needle-type material picking component 4 to perform the material picking action. The lifting and moving drive assembly 22 moves along the front and rear direction of the frame 1 under the drive of the horizontal moving drive mechanism 2. The needle-type material picker 4 descends under the drive of the lifting and moving drive assembly 22, so that the needle-type material picker 4 moves to the material picker station 11 and presses down on the material tray 4. When the needle-type material picker 4 elastically presses against the material tray 3, the hook 41 of the needle-type material picker 4 can pick up the workpiece 20 on the material tray 3 by hooking it. At this time, the workpiece 20 is hooked on the needle-type material picker 4. The needle-type material picker 4 moves the workpiece 20 to the next station under the drive of the horizontal moving drive assembly 21 and the lifting and moving drive assembly 22. The material tray 3 is removed from the material picker station 11 by descending.

[0035] By incorporating a needle-type material picker, which is elastically mounted at the output end of the moving drive mechanism, the needle-type material picker can move up and down and horizontally relative to the frame under the drive of the moving drive mechanism. This allows the needle-type material picker to press against or move away from the workpiece on the tray. The needle-type material picker has hooks; when it elastically presses against the tray, the hooks can hook onto the workpiece to pick it up. The elastic pressing of the needle-type material picker can hook onto the workpiece on the tray without damaging it through rigid collision. This allows the material to be picked up by hooking the workpiece and then moved to the next workstation. It is understandable that since the workpiece is a shoe piece with ventilation holes and the hook itself is relatively small, the hooking action when the hook is pressed down will not affect the pass rate of the workpiece, which meets the production requirements. It is precisely this workpiece requirement that makes the needle-type material picker with hook more suitable for loading and unloading shoe pieces, avoiding the deformation of shoe pieces and gripping failure caused by the gripper, and has the advantages of good loading and unloading effect and high accuracy.

[0036] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
