[0002] Insoles are placed inside shoes and between the foot and the sole. Their purpose is to increase the comfort of the foot when walking. As people's quality of life continues to improve, people's requirements for shoes and insoles are also getting higher and higher. Currently, one important process in the manufacturing of insoles is to cut the material into the shape of the insole.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figure 1-8 As shown, a fully automatic shoe insole trimming machine includes: a base 1, a worktable 2, a shoe insole feeding device 3, a rotary feeding device 4, a vision positioning system 5, a shoe insole trimming head 6, and a conveying device 7.

[0028] The workbench 2 is mounted on the base 1 and has multiple adsorption holes 21 for adsorbing and positioning insoles. A suction module 22 corresponding to the adsorption holes 21 is located on the lower surface of the workbench 2. The workbench 2 also has a finished product unloading hopper 23. The insole feeding device 3 includes a feeding frame 31 for limiting multiple insoles stacked vertically, a first support frame 32 and a second support frame 33 for simultaneously supporting the two ends of the lower surfaces of insoles with different heights, a first lifting module 34 and a second lifting module 35 for driving the first support frame 32 and the second support frame 33 to rise synchronously, and a device installed on both sides of the upper end of the feeding frame 31 for simultaneously detecting whether the two sides of the insole are aligned. The first sensor 36 and the second sensor 37 reach the limit position; the rotary feeding device 4 is located outside the workbench 2 and is used to pick up and transfer the insole lifted by the insole feeding device 3 to the suction hole 21 of the workbench 2; the visual positioning system 5 is located above the suction hole 21; the insole trimming head 6 is located outside the workbench 2; the conveying device 7 is located on the machine base 1 and is used to pick up, grab or press the insole positioned by the suction hole 21 and transfer it to the insole trimming head 6 and drive the insole to rotate so as to cooperate with the insole trimming head 6 to trim the insole around the whole circle or to transfer the trimmed insole to the finished product unloading hopper 23.In operation, this invention comprises multiple insoles of varying heights at their front and rear ends, stacked within a feeding rack 31. The feeding rack 31 limits the position of the insoles. A first support frame 32 and a second support frame 33 respectively support the lower ends of the bottom insole 100. A first sensor 36 and a second sensor 37 simultaneously detect whether both sides of the insole 100 have reached their limit positions. When both sides reach their limit positions, the rotating feeding device 4 picks up the insole 100, lifted by the feeding device 3, and transfers it to the suction hole 21 on the workbench 2. Simultaneously, a first lifting module 34 and a second lifting module 35 drive the first support frame 32 and the second support frame 33 to rise synchronously, ensuring that the top insole 100 remains parallel to the work surface. Subsequently, the suction module 22 draws suction from the suction hole 21. Air is used to position the insole 100 placed on the suction hole 21. Then, the vision positioning system 5 takes a picture of the positioned insole 100 to determine its shape, the starting point of the trimming, or to locate the coordinates of the insole 100, so that the conveying device 7 can transfer the insole 100 and the special trimming head 6 can trim the insole 100. Subsequently, the conveying device 7 will suck air from the suction hole 21. The positioned insole 100 is picked up, grabbed, or pressed and conveyed to the insole 100 trimming head 6, which drives the insole 100 to rotate so that it can be trimmed around the entire insole 100. After the insole 100 trimming head 6 has trimmed the entire insole 100, the conveying device 7 moves the trimmed insole 100 to the finished product unloading hopper 23, thereby completing the unloading of the finished insole 100. In other words, this utility model can automatically feed / supply insoles 100, automatically transfer insoles 100 to the workbench for positioning, and then use the vision positioning system 5 to take pictures of the positioned insoles 100 to determine the shape of the insoles 100, or to determine the starting point of the trimming, or to use coordinate positioning of the insoles 100. Finally, the conveying device 7 picks up, grabs or presses the insoles 100 positioned by the suction hole 21 and conveys them to the insoles 100 trimming head 6, driving the insoles 100 to rotate to cooperate with the insoles 100 trimming head. The machine head 6 trims the entire circumference of the insole 100, and then the trimmed insole 100 is transferred to the finished product unloading hopper 23 to complete the unloading of the finished insole 100. The whole process is fully automated, with minimal labor intensity and high work efficiency. It can also ensure the accuracy of the placement of the insole 100, thereby ensuring the accuracy of the edge cutting of the insole 100 and guaranteeing product quality. Furthermore, this utility model can also perform full-circumference trimming of the insole 100 to meet production needs and further improve the quality of trimming, making this utility model highly competitive in the market.

The adjusting frame 24 is U-shaped and distributed around the upper periphery of the feeding rack 31. In other words, the heights of the first sensor 36 and the second sensor 37 can be adjusted individually using the first adjusting plate 25 and the second adjusting plate 26, or simultaneously using the adjusting frame 24, to meet different adjustment requirements and achieve precise adjustment.

[0034] The rotary feeding device 4 includes a bracket 41 mounted on the workbench 2, a rotary cylinder 42 mounted on the bracket 41, a feeding arm 43 mounted on the rotary cylinder 42 and capable of rotating 90 degrees by the rotary cylinder 42, a third lifting module 44 mounted at the end of the feeding arm 43, a first lifting frame 45 mounted at the lower end of the third lifting module 44 and capable of being lifted and lowered by the third lifting module 44, and a first suction cup 46 and a second suction cup 47 mounted on both sides of the lower end of the first lifting frame 45 and simultaneously adsorbing both sides of the upper surface of the same insole 100. This rotary feeding device 4 is extremely simple and can achieve the purpose of stably adsorbing, positioning, and rotating the insole 100.

[0035] The machine base 1 is also provided with an inclined waste discharge trough 11, and the upper end of the machine base 1 is also provided with a waste inlet 12 for collecting the edge material formed by the shoe insole 100 trimming head 6 after trimming the shoe insole 100. The waste inlet 12 is located next to the shoe insole 100 trimming head 6, so as to realize the rapid collection of the edge material formed by the shoe insole 100 trimming head 6 after trimming the shoe insole 100 and avoid the phenomenon of edge material being scattered.

[0036] The insole 100 trimming head 6 is mounted on the base 1 in an adjustable relative position via several guide rails 61. Users can adjust the position of the insole 100 trimming head 6 to meet different usage requirements. During use, a locking mechanism can be used to lock the insole 100 trimming head 6 onto the base to ensure its working quality. A control button box 13 is provided at the front end of the base 1, with multiple control buttons 131 for controlling the device, making it more convenient to use.

[0037] The workbench 2 is mounted on the machine base 1 via multiple balance adjustment structures 27 to adjust its balance and height. Each balance adjustment structure 27 includes an adjustment rod 271 and upper and lower adjustment seats 272 and 273, respectively, mounted at the upper and lower ends of the adjustment rod 271. The upper adjustment seat 272 is fixed to the lower end face of the workbench 2, and the lower adjustment seat 273 is fixed to the upper end face of the machine base 1. The adjustment rod 271 is a positive and negative screw, and the upper and lower adjustment seats 272 and 273 respectively have positive and negative threaded holes. When the adjustment rod 271 rotates, the upper and lower adjustment seats 272 and 273 move towards each other to adjust the height.

[0038] The conveying device 7 includes a pressing plate 71 for pressing down and conveying the insole 100 positioned on the workbench 2 to the insole 100 trimming head 6 and driving the insole 100 to rotate; a rotary drive mechanism 72 for driving the pressing plate 71 to rotate; and an XYZ three-axis drive mechanism 73 for driving the rotary drive mechanism 72 to move in the XYZ three-axis directions. The rotary drive mechanism 72 includes a second lifting frame 73 mounted on the XYZ three-axis drive mechanism 73.

The lower end of the rotary shaft 724 extends beyond the lower end of the second lifting frame 731, and the pressure plate 71 is fixedly mounted on the lower end of the rotary shaft 724. During operation, the rotary drive mechanism 72 uses the rotary motor 722 to increase rotational power, while the reducer 721 reduces speed and increases torque, thereby driving the rotary shaft 724 to rotate stably. This, in turn, drives the pressure plate 4 to rotate stably, forcibly rotating the shoe or sock to be sewn while pressed by the pressure plate 71, to cooperate with the machine head in cutting excess material and sewing overhead. The rotating shaft 724 is mounted in the second lifting frame 731 via the bearing 723, making its rotation more stable and smoother.

[0039] The XYZ three-axis drive mechanism 73 is also provided with a stop block 732, and a buffer block 701 for preventing excessive descent is also provided on the outside of the second lifting frame 731. The buffer block 701 is located above the stop block 732. When the descent stroke of the second lifting frame 731 exceeds the limit, the buffer block 701 will press against the upper surface of the stop block 732 to achieve the buffering function, thereby preventing the second lifting frame 731 from continuing to descend.

[0040] The lower end of the second lifting frame 731 is also provided with a third sensor 702 for detecting the rotation angle and / or speed of the rotating shaft 724. The third sensor 702 has a sensing groove 703. The lower end of the rotating shaft 724 is also provided with a sensing disk 704. The outer edge of the sensing disk 704 is placed in the sensing groove 703, and the outer edge of the sensing disk 704 is provided with a plurality of holes evenly distributed along the circumference. The third sensor 702 and the sensing disk 704 can detect the rotation angle and / or speed of the rotating shaft 724, thereby enabling better control of the entire rotating drive mechanism 72, resulting in higher operating accuracy and better working quality.

[0041] In summary, this utility model can automatically feed / feed insoles 100, automatically transfer insoles 100 to the workbench for positioning, and then use the vision positioning system 5 to photograph the positioned insoles 100 to determine their shape, the starting point of the trimming, or to perform coordinate positioning of the insoles 100.

The machine head 6 trims the entire circumference of the insole 100, and then the trimmed insole 100 is transferred to the finished product unloading hopper 23 to complete the unloading of the finished insole 100. The whole process is fully automated, with minimal labor intensity and high work efficiency. It can also ensure the accuracy of the placement of the insole 100, thereby ensuring the accuracy of the edge cutting of the insole 100 and guaranteeing product quality. Furthermore, this utility model can also perform full-circumference trimming of the insole 100 to meet production needs and further improve the quality of trimming, making this utility model highly competitive in the market.
