Description

Technical Field

[0001] This utility model relates to the field of shoe last feeding technology, and in particular to a shoe last feeding device. Background Technology

[0002] In each process of shoe production line, the shoe last with the upper attached needs to be removed from the conveyor line, and after the corresponding process is completed, it needs to be put back into the conveyor line to continue conveying.

[0003] Traditionally, this loading and unloading process is usually done manually, which is not only inefficient but also increases labor intensity and costs. To optimize the production process and improve efficiency, the current industry trend is to use robotic arms to automate the loading and unloading of shoe lasts, significantly accelerating the process and shortening the production cycle. However, in the automated loading and unloading process, the gripping position of the robotic arm on the shoe last depends entirely on the pre-set program, making it difficult to adjust according to the actual position of the shoe last. Furthermore, the gripping accuracy is limited, often resulting in slight deviations when the shoe last is transferred to the next processing equipment. This can cause the shoe last to fail to fit into the processing station, requiring additional operators to assist with unloading, thus increasing the cost of the automated production line.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment of this utility model, such as Figure 1-5As shown, a shoe last feeding device is provided, including a workbench 10, a transmission mechanism 11 for conveying shoe lasts on the workbench 10, a feeding station for placing shoe lasts on the transmission mechanism 11, and a feeding mechanism 20 and a detection mechanism. The feeding mechanism 20 is located on the workbench 10 and on one side of the transmission mechanism 11, and is used for picking up and placing shoe lasts. The detection mechanism includes a first detection component 31 and a second detection component 32. The first detection component 31 is located on the output end of the feeding mechanism 20 and is used for position detection when the shoe last is picked up or put down. The second detection component 32 is located on the workbench 10 and between the transmission mechanism 11 and the feeding mechanism 20, and is used for detecting the fixed position on the shoe last for fixing it to the feeding station.

[0032] In this embodiment, the transmission mechanism 11 can be a conveyor belt or a linear transmission module. The material placement seat 111 is transmitted to the next work station through the transmission mechanism 11. The automated transmission of the shoe last with the shoe body eliminates the need for manual feeding, improves production efficiency, and reduces production costs.

[0033] By setting up a first detection component 31 and a second detection component 32, the first detection component 31 in the feeding mechanism 20 captures images of the incoming shoe last to confirm the clamping position. Then, the clamping component in the feeding mechanism 20 clamps the shoe last and sends it above the second detection component 32 to locate the insertion hole position of the shoe last. Then, the feeding mechanism 20 moves it to the feeding station. At the same time, the first detection component 31 repositions the placement seat 111 on the feeding station. Finally, the insertion hole of the shoe last is inserted into the placement seat 111, realizing automatic positioning of the shoe last feeding. Compared with the traditional manual feeding, no additional operators are needed, simplifying the shoe last feeding steps, effectively reducing the shoe last feeding time, improving feeding efficiency, and reducing cost expenditure.

[0034] Preferably, the first detection component 31 includes a first support frame 311 and a first detection unit 312. The first support frame 311 is vertically disposed below the output end of the feeding mechanism 20. The end of the first support frame 311 is provided with a horizontally extending first support portion. The first detection unit 312 is disposed on the first support portion. The first support portion is equivalent to a first lighting unit 313 disposed on the other side of the first detection unit 312. In this embodiment, the first detection unit 312 is a CCD camera, and the first lighting unit 313 is an illumination device, etc. By setting the first detection unit 312, the clamping position of the shoe last and the insertion position on the placement seat 111 are positioned, which facilitates the clamping and unloading of the feeding mechanism 20 without the need for additional operators, thereby improving feeding efficiency and reducing costs. At the same time, by setting the first lighting unit 313, it is ensured that the first detection unit 312 can clearly capture the object during positioning, thereby improving the positioning accuracy of the first detection unit 312 and reducing the occurrence of positioning errors.

[0035] Preferably, the second detection component 32 includes a second support frame 321 and a second detection unit 322. The second support frame 321 is disposed on the workbench 10 and located between the transmission mechanism 11 and the loading mechanism 20. The top of the second support frame 321 is provided with a horizontally extending second support portion. The second detection unit 322 is disposed on the second support portion. The second support portion is equivalent to a second lighting unit 323 disposed on the other side of the second detection unit 322. In this embodiment, the second detection unit 322 is a CCD camera, and the second lighting unit 323 is an illumination device, etc. By setting the second detection unit 322, the insertion hole of the shoe last is positioned by the second detection unit 322, so that the shoe last can be accurately inserted into the placement seat 111 without the need for additional operator assistance, thereby improving loading efficiency and reducing cost expenditure. At the same time, by setting the second lighting unit 323, it is ensured that the second detection unit 322 can clearly capture the object during positioning, thereby improving the positioning accuracy of the second detection unit 322 and reducing the occurrence of positioning errors.

[0036] Preferably, the feeding mechanism 20 includes a feeding robot 21 and a clamping assembly for holding the shoe last. The feeding robot 21 is mounted on the worktable 10 and located on one side of the second detection assembly 32. The clamping assembly is located on the output end of the feeding robot 21. The first detection assembly 31 is located on one side of the clamping assembly. In this embodiment, the feeding robot 21 is an industrial robot capable of multi-dimensional angle or position adjustment. By setting the feeding robot 21, the clamping assembly can clamp or release the shoe last in multiple directions, and the feeding robot 21 can flexibly adjust the spatial position of the clamping assembly without additional auxiliary adjustment, improving the flexibility of the clamping assembly and thus improving the feeding efficiency of the shoe last.

[0037] Specifically, the clamping assembly includes a clamping connecting plate 221, a clamping drive 222, and a clamping component. The clamping connecting plate 221 is located on the output end of the loading robot 21. The clamping drive 222 is located on one side of the clamping connecting plate 221 and is a cylinder. The clamping component is located on the other side of the clamping connecting plate 221 and is connected to the output end of the clamping drive 222. The output end of the clamping drive 222 retracts inward or extends outward, driving the clamping component to clamp or open, thereby realizing the clamping or releasing of the shoe last.

[0038] Furthermore, the clamping components include a clamping push plate 223 and a guide plate 224. The clamping push plate 223 is located on the output end of the clamping drive member 222, and the guide plate 224 is located on the end of the clamping push plate 223 away from the clamping drive member 222. Two sets of symmetrically distributed grippers 225 are slidably arranged on the guide plate 224. Each gripper 225 has a locking part that engages with the shoe last. The locking part is an elastic block corresponding to a slot on the shoe last, and the contact part of the elastic block has an arc structure. When the output end of the clamping drive member 222 retracts inward or extends outward, it drives the guide plate 224 on the clamping push plate 223 to move backward or forward. The guide plate 224 drives the two sets of grippers 225 to clamp or open relative to each other, thereby clamping or releasing the shoe last, increasing the automation level of the feeding device and improving the feeding efficiency of the shoe last.

[0039] Furthermore, a pulley 226 is provided at one end of the gripper 225. Two sets of guide grooves are provided on the guide plate 224, which are slidably connected to the pulley 226 and are inclined. A clamping guide rail is provided between the clamping connecting plate 221 and the clamping push plate 223 and the gripper 225, respectively. By providing the guide grooves and clamping guide rails, the stability of the gripper 225 when opening or clamping is improved, preventing wobbling during clamping or opening.

[0040] Preferably, the conveying mechanism 11 is provided with a placement seat 111 corresponding to the loading station. Both sides of the placement seat 111 are provided with fixing mechanisms for securing the placement seat 111. By providing fixing mechanisms, the placement seat 111 can be stably fixed to the loading station, facilitating the subsequent loading of shoe lasts.

[0041] Furthermore, the fixing mechanism includes a fixing bracket 112, a fixing drive component 113, and a fixing push plate 114. The fixing bracket 112 is mounted on the worktable 10. The fixing drive component 113 is mounted on the fixing bracket 112, and the fixing drive component 113 is a cylinder, with its output end connected to the fixing push plate 114. The end of the fixing push plate 114 is provided with a fixing block that is tightly connected to the shoe last, and a fixing guide rail 115 is provided between the fixing push plate 114 and the fixing bracket 112.

[0042] In this embodiment, the fixing block is made of an elastic material, such as rubber. The elastic deformation of the fixing block allows for a better and tighter fit between the contact surfaces of the two components, preventing incomplete contact and improving the fixing efficiency of the placement seat 111. During shoe last loading, the output ends of the two sets of fixing drive components 113 extend outwards, respectively driving the fixing push plates 114 to move towards both sides of the placement seat 111. The two sets of fixing blocks firmly press the two ends of the placement seat 111 together, ensuring stable fixation of the seat at the loading station. This facilitates the subsequent loading mechanism 20 placing the shoe last onto the placement seat 111, improving the shoe last loading efficiency.

[0043] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way.
