Description

Technical Field

[0001] The invention belongs to the field of waste shoe recycling, and in particular relates to an automatic insole disassembly device. Background Art

[0002] After the shoes are discarded, the leather fabric on the upper, the rubber on the sole and the sponge on the insole are all materials that still have a certain value. It is extremely wasteful to directly discard them. Recycling and reusing the discarded shoes is more environmentally friendly and saves resources. In the prior art, the upper and the sole are usually directly cut and separated, but some shoes are made by completely covering the upper with the shoe last and then adhering it to the sole during the production process. Direct cutting can easily cause the upper to remain on the sole, and since the shoes often come with insoles, if the insoles in the shoes are not taken out, it is easy to cause material contamination when separating the insoles from the uppers, and subsequent manual selection is time-consuming and laborious. If the insole is taken out before separating the upper and the sole, due to the shape of the shoe itself, it is difficult for the machine to complete the work of automatically removing the insole, and it needs to be done manually, which greatly wastes labor and needs to be improved. Summary of the invention

[0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide an automatic insole disassembly device.

[0004] The present invention adopts the following technical solution:

[0005] An automatic insole disassembly device comprises a conveying mechanism, a shoe upper cutting mechanism, a shoe upper supporting mechanism and an insole stripping mechanism.

[0006] The conveying mechanism is used to convey the shoes to be disassembled, and comprises a first conveying belt and a second conveying belt, the first conveying belt and the second conveying belt are connected in sequence, and the shoes are conveyed out of the device from the first conveying belt via the second conveying belt;

[0007] The shoe upper cutting mechanism is arranged above the first conveyor belt and divides the shoe upper into two parts along the length direction;

[0008] The shoe upper supporting mechanism is arranged on the second conveyor belt to separate and stretch the divided shoe uppers in opposite directions;

[0009] The insole stripping mechanism is arranged on the second conveyor belt, and comprises a manipulator and a grabbing assembly. The manipulator is arranged beside the second conveyor belt. The grabbing assembly is arranged at the end of the manipulator to grab the insole from the second conveyor belt, so that the remaining sole and upper continue to be conveyed forward.

[0010] Preferably, the grabbing assembly includes a base, a telescopic rod and a vacuum suction cup, the base is arranged at the end of the manipulator; a plurality of telescopic rods are arranged, which can be telescopically arranged on the base; the vacuum suction cup is arranged on the telescopic rod and can move back and forth with the telescopic rod; the telescopic rod can adjust the length to use insoles of different heights so that the vacuum suction cup can adsorb the sole.

[0011] Preferably, the upper cutting mechanism includes a bracket and a circular saw, the bracket is mounted above the first conveyor belt; the circular saw is arranged on the bracket and extends downward to above the first conveyor belt, the cutting direction of the circular saw is consistent with the conveying direction of the first conveyor belt and is located on the center line of the first conveyor belt.

[0012] Preferably, the conveying mechanism is also provided with limiting side plates, which are arranged on both sides of the first conveyor belt and the second conveyor belt to form a transportation channel on the conveyor belt for only one shoe to pass through; a plurality of first push plates are arranged on the first conveyor belt, and a plurality of second push plates are arranged on the second conveyor belt.

[0013] Preferably, the shoe upper supporting mechanism is arranged on the second conveyor belt and connected to the limiting side plates, including a supporting plate and a connecting plate. Two support plates are provided, extending along the conveying direction of the second conveyor belt and symmetrically arranged on the second conveyor belt. The front ends of the two support plates gradually approach each other forward and are connected to each other. When the shoes pass through the support plates, the shoe upper opens to both sides and the insole is exposed between the two support plates. The connecting plate is arranged between the support plate and the limiting side plates, and the spacing between the support plates is smaller than the spacing between the limiting side plates.

[0014] Preferably, the connecting plate is connected at the highest points of the limiting side plate and the support plate, the highest points of the limiting side plate and the support plate are higher than the highest point of the shoe, and a transportation channel for the shoe to pass through is formed between the connecting plate, the support plate and the limiting side plate.

[0015] Preferably, the lowest point of the circular saw is lower than the height of the sole, the height of the first push plate is higher than the lowest point of the circular saw and a clearance groove is formed thereon for the circular saw to pass through.

[0016] Preferably, it also includes a control system, which includes a sensor and a controller. The sensor is arranged on the second conveyor belt and monitors the position of the shoe in real time and feeds back to the controller; the controller receives the signal from the sensor and controls the second conveyor belt to stop and drives the insole peeling mechanism to remove the insole.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects: waste shoes are placed on the first conveyor belt and conveyed backwards, the upper is divided into two parts from the middle by the upper cutting mechanism and conveyed to the second conveyor belt, the cut upper is separated to both sides by the upper supporting mechanism on the second conveyor belt, so that most of the insole is directly exposed, and finally the gripping assembly is controlled by the manipulator to reach into the shoe to remove the insole, after the insole is removed, the insole can be recycled and classified, and the subsequent separation of the upper and the sole is convenient, and at the same time, the upper is cut in advance, so that the insole that is difficult to remove automatically can also be operated by machinery, saving labor and improving production efficiency;

[0018] The telescopic rod can adjust the position of the vacuum suction cup so that it can be used at the height of different shoe insoles, ensuring the accuracy of insole adsorption and facilitating the removal of the insole;

[0019] By mounting the circular saw on the bracket, the vibration generated by the circular saw during cutting can be effectively prevented from interfering with the work of the conveying mechanism, and the effect of cutting the upper can also be improved;

[0020] The limiting side plate can limit the conveyor belt to only one shoe passing through at a time, and the limiting baffle can limit the shoe on the conveyor belt. When the shoe passes through the circular saw, a certain resistance can be generated under the action of the limiting baffle, so that the shoe can pass through the circular saw;

[0021] When the shoe passes the front end of the support plate, it gradually separates to both sides, and the uppers on both sides are restricted between the support plate and the limiting side plates. At this time, since the shoe is stuck as a whole by the support plate, the shoe will not be taken away with the manipulator when the insole is taken out, and the manipulator is assisted to remove the insole.

[0022] The space formed by the connecting plate, the supporting plate and the limiting baffle plate can be sufficient to accommodate the upper, so as to prevent the upper from being stuck outside the supporting plate due to being too high, thus affecting the normal use of the device;

[0023] The lowest point of the circular saw is lower than the height of the sole, so as to avoid the upper of some shoes being fully covered and connected to the sole, and to ensure that the upper can be completely separated during cutting. The height of the first push plate is higher than the lowest point of the circular saw and a clearance groove is formed on it for the circular saw to pass through, so as to enhance the thrust of the first push plate while preventing the circular saw from cutting the first push plate, thereby improving the safety of the device.

[0024] When the shoe moves to the position where the sensor is set, the signal is fed back to the controller, and the controller controls the second conveyor belt to stop at the specified position and controls the robot to work, driving the robot to control the grabbing component to remove the insole from the shoe.

DETAILED DESCRIPTION

[0036] The present invention is further described below through specific implementation modes.

[0037] Reference Figures 1 to 10 As shown, a shoe disassembly production line includes a conveying mechanism 1, an upper cutting mechanism 2, an upper supporting mechanism 3, an insole stripping mechanism 4, a sole heating mechanism 5, a disassembly mechanism 6, and a control system.

[0038] The conveying mechanism 1 is used to convey shoes to be disassembled, and includes a first conveyor belt 11 and a second conveyor belt 12. The first conveyor belt 11 and the second conveyor belt 12 are connected in sequence to convey the shoes to be disassembled. It also includes a limiting side plate 13, which is arranged on both sides of the first conveyor belt 11 and the second conveyor belt 12, forming a transportation channel on the conveyor belt for only one shoe to pass through. Specifically, the front end of the limiting side plate 13 is opened outward to guide the shoes on the first conveyor belt 11 into the transportation channel. A plurality of first push plates 14 are evenly arranged on the first conveyor belt 11, and a plurality of second push plates 15 are evenly arranged on the second conveyor belt 12, and the shapes of the first push plates 14 and the second push plates 15 are adapted to the heels of the shoes.

[0039] The upper cutting mechanism 2 is arranged above the first conveyor belt 11 to cut the uppers of the shoes passing through. The upper cutting mechanism 2 includes a bracket 21 and a circular saw 22. The bracket 21 is arranged above the first conveyor belt 11. The circular saw 22 is arranged on the bracket 21 and extends downward to the top of the first conveyor belt 11. The cutting direction of the circular saw 22 is consistent with the conveying direction of the first conveyor belt 11 and is located on the center line of the first conveyor belt 11. The circular saw 22 is arranged by the bracket 21, which can effectively avoid the vibration generated by the circular saw 22 when cutting and interfere with the work of the conveying mechanism 1, and at the same time, it can also improve the effect of upper cutting. Specifically, the height of the first push plate 14 is higher than the lowest point of the circular saw 22 and a clearance groove 16 is formed on it for the circular saw 22 to pass through. While increasing the thrust of the first push plate 14 on the shoes, the circular saw 22 can also pass through the clearance groove 16 to cut the shoes, and the upper is divided into two without lowering the sole. Even if the upper is bonded to the sole by a coating method, the upper can also be divided into two, which is convenient for the subsequent separation of the upper and the sole.

[0040] The upper support mechanism 3 is arranged on the second conveyor belt 12 to separate and stretch the divided uppers in opposite directions. The upper support mechanism 3 is arranged on the second conveyor belt 12 and connected to the limiting side plate 13, and includes a support plate 31 and a connecting plate 32. Two support plates 31 are provided, extending along the conveying direction of the second conveyor belt 12 and symmetrically arranged on the second conveyor belt 12. The front ends of the two support plates 31 gradually approach forward and are connected to each other. When the shoe passes through the support plate 31, the upper opens to both sides and the insole is exposed between the two support plates 31; the connecting plate 32 is arranged between the support plate 31 and the limiting side plate 13, and the spacing between the support plates 31 is smaller than the spacing between the limiting side plates 13. Specifically, the connecting plate 32 is connected to the highest point of the limiting side plate 13 and the supporting plate 31. The highest points of the limiting side plate 13 and the supporting plate 31 are higher than the highest point of the shoe. A transportation channel for the shoe to pass through is formed between the connecting plate 32, the supporting plate 31 and the limiting side plate 13. The shoe gradually separates to both sides when passing the front end of the supporting plate 31, and the uppers on both sides are restricted between the supporting plate 31 and the limiting side plate 13. At this time, since the shoe is stuck as a whole by the supporting plate 31, the shoe will not be taken away with the manipulator when the insole is taken out, thereby assisting the manipulator in disassembling the insole.

[0041] The insole stripping mechanism 4 is arranged on the second conveyor belt 12 and can be inserted into the shoes with the uppers separated to remove the insoles. The insole stripping mechanism 4 is arranged on the second conveyor belt 12, and includes a manipulator 41 and a grabbing assembly 42. The manipulator 41 is arranged beside the second conveyor belt 12; the grabbing assembly 42 is arranged at the end of the manipulator 41, and includes a base 421, a telescopic rod 422 and a vacuum suction cup 423. The base 421 is arranged at the end of the manipulator 41; a plurality of telescopic rods 422 are arranged, and can be telescopically arranged on the base 421; the vacuum suction cup 423 is arranged on the telescopic rod 422 and can move back and forth with it; the telescopic rod 422 can adjust the length to use insoles of different heights so that the vacuum suction cup 423 can adsorb the sole, grab the insole from the second conveyor belt 12, and allow the remaining sole and upper to continue to be conveyed forward. The vacuum suction cup 423 is controlled by the robot to reach into the shoe to remove the insole, and the upper is cut in advance, so that the insole that is difficult to remove automatically can also be removed mechanically, saving labor, improving production efficiency, and making use of the insole that is difficult to reuse in conventional recycling, saving costs.

[0042] The sole heating mechanism 5 is arranged on the second conveyor belt 12 and can be extended into the shoe with the insole removed to heat the sole, and includes a telescopic component 51 and a heating component 52. The telescopic component 51 is arranged on the second conveyor belt 12; the heating component 52 is arranged at the end of the telescopic component 51 and can move downward with it to the second conveyor belt 12 to heat the sole. The telescopic component 51 includes a gantry 511 and a cylinder 512. The gantry 511 is arranged on the second conveyor belt 12; the cylinder 512 is arranged on the gantry 511 and can be extended in the downward direction to approach the shoe on the second conveyor belt 12; the heating component 52 includes a heating block 521 arranged at the end of the cylinder 512 and a heat resistance wire 522 distributed on the contact surface between the heating block 521 and the sole, which can move downward with the cylinder 512 and close to the sole to heat it. The sole is heated by the heat resistance wire 522, so that the glue between the upper and the sole is quickly melted. Specifically, the shape of the heating block 521 is similar to that of the sole, which facilitates comprehensive heating of the sole and ensures uniform heating.

[0043] The splitting mechanism 6 is arranged at the end of the second conveyor belt 12 to separate the heated upper and sole. The splitting mechanism 6 includes a groove 61, a clamp 62 and a hydraulic cylinder 63. The groove 61 is formed inward from both sides of the limiting side plate 13 and penetrates the connecting plate 32 and the support plate 31; two clamps 62 are provided, which can be movably arranged in the groove 61 to clamp the shoe upper moved there; the hydraulic cylinder 63 is arranged on both sides and connected to the clamp 62 to drive it to move back and forth, and can cooperate with the support plate 31 to limit the movement of the sole through the support plate 31 and then pull the upper to separate the upper from the sole. When splitting, the clamp 62 clamps the upper, and under the action of the support plate 31, the sole is restricted on the conveyor belt, and the upper is pulled to both sides to complete the separation of the upper and the sole.

[0044] The control system includes a first sensor, a second sensor, a third sensor and a controller. The first sensor is arranged on the second conveyor belt 12; the second sensor is arranged on the second conveyor belt 12; the third sensor is arranged on the second conveyor belt 12; the controller is connected to the first sensor, the second sensor, the third sensor, the insole stripping mechanism 4, the sole heating mechanism 5, the splitting mechanism 6 and the second conveyor belt 12 respectively, and controls the second conveyor belt 12 to stop and controls the insole stripping mechanism 4, the sole heating mechanism 5 and the splitting mechanism 6 to work respectively according to the signals fed back by the first sensor, the second sensor and the third sensor.

[0045] When the device is used to disassemble shoes, the first conveyor belt 11 transports the items upward, and the shoes are placed at the front end of the first conveyor belt 11. The shoes are guided by the limiting side plate 13 and moved forward under the action of the first push plate 14. When passing through the upper cutting mechanism 2, the upper is divided into two parts from the middle by the circular saw 22, and the insole and part of the sole in the shoe are cut at the same time. The shoes after cutting are transferred to the second conveyor belt 12 under the conveyance of the first conveyor belt 11. When the shoes move to the second conveyor belt 12, they move forward under the action of the second push plate 15, and the cut upper is spread to both sides by the support plate 31, and the sole is limited under the support plate 31. When the first sensor detects the shoes, it feeds back the signal to the controller, and the controller controls the second conveyor belt 12 to stop at the specified position and controls the manipulator to operate the vacuum suction cup 423 to suck up the insole from the shoe and disassemble it. After disassembly, the second conveyor belt 12 continues to transport forward. When the second sensor detects the shoes, it feeds back the signal to the controller, and the controller controls the second conveyor belt 12 to stop at the specified position and moves the cylinder 512 downward, so that the heating block 521 is attached to the sole to heat the sole, so that the glue between the upper and the sole melts, and the second conveyor belt 12 continues to convey forward after the heating is completed. When the third sensor detects the shoes, it feeds back the signal to the controller, and the controller controls the second conveyor belt 12 to stop at the specified position, and drives the clamping claw 62 to clamp the uppers on both sides, and controls the hydraulic cylinders 63 at both ends to shrink to both sides, so that the upper and the sole are separated, and the sole is transported out of the device with the second conveyor belt 12, and the upper is released by the clamping claw 62 and falls into the collection device on both sides of the second conveyor belt 12. It is also possible to control the intermittent stop of the second conveyor belt 12 so that the insole stripping mechanism 4, the sole heating mechanism 5 and the splitting mechanism 6 work simultaneously when the second conveyor belt 12 stops, and the assembly line is automatically disassembled, which can accurately classify different types of materials to be recycled, improve the recycling efficiency, and has high practicality.

[0046] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope covered by the patent of the present invention.
