Description

Technical Field

[0001] This invention relates to the field of shoe material recycling technology, and in particular to a device and method for separating the upper and sole of discarded shoes. Background Technology

[0002] As living standards improve, people's demand for footwear is increasing, resulting in a large amount of discarded shoe materials every year. The recycling of shoe materials has become a hot topic of discussion.

[0003] Globally renowned sportswear brands such as Adidas and Nike are also paying close attention to the recycling of footwear materials. For example, CN201980032639.9 discloses footwear articles, manufacturing equipment and processes for forming footwear using recycled plastics, which mainly involves recycling thermoplastic elastomers or EVA, grinding them, adding a foaming agent activated at high temperature, and then placing them into a final mold to form the sole.

[0004] Regarding specific methods for recycling waste shoe materials, existing technologies commonly utilize crushing. For example, CN201810207978.3 discloses a comprehensive processing device for dismantling old shoes and recycling useful materials. This device uses a multi-stage crushing mechanism and a screening and separation module composed of blowers to separate old shoe particles of different masses into layers within the chamber for classification and recycling. Existing equipment directly crushes the waste shoe materials, and the resulting fragments can only separate light and heavy materials through air separation. However, due to the diverse types of old shoes and the different materials used for the uppers and soles, which have varying properties, further sorting is necessary for better recycling. The fine fragments, however, hinder this further sorting. Therefore, there is an urgent need for a more efficient dismantling device that can separate shoe soles and uppers. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a device and method for separating the upper and lower surfaces of discarded shoes that can adapt to different sizes of discarded shoe materials and completely separate the upper and lower surfaces of the shoes.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a device for separating the upper and lower surfaces of discarded shoes, characterized in that it includes a conveyor belt, a positioning device, a first lifting drive, a three-section movable shoe last, a second lifting drive, and a positioning plate;

[0007] The positioning device includes two sets of drive cylinders symmetrically arranged on both sides of the conveyor belt, a push plate, a spring, a clamping plate, and a positioning pin connected to the drive cylinders. There are several clamping plates, and adjacent clamping plates are rotatably connected. The clamping plates are connected to the push plate through the springs. The drive cylinders drive the push plate to move. There are several positioning pins, which are located on the clamping plates and extend outwards. The positioning pins on the clamping plates on both sides are arranged facing each other.

[0008] The three movable shoe lasts are installed on the first lifting drive. The three movable shoe lasts include a toe block, a mid-section block, and a heel block. The toe block and the mid-section block, and the mid-section block and the heel block can rotate at controllable angles. The outer shells of the toe block, the mid-section block, and the heel block are made of magnetic material. The positioning plate is installed on the second lifting drive and is located above the three movable shoe lasts. The positioning plate is provided with several electromagnets. When the electromagnets are energized, a clamping and adsorption force is formed between the positioning plate and the three movable shoe lasts.

[0009] Furthermore, the three-section movable shoe last also includes several connectors and several servo motors. The connectors are located between the toe block and the middle block, and between the middle block and the heel block. Each end of the connector is connected to a servo motor, and the servo motors are located inside the toe block, the middle block, and the heel block.

[0010] Furthermore, the positioning plate is equipped with three sets of electromagnets, which are respectively located on the upper side of the toe block, the middle block, and the heel block to attract the corresponding components.

[0011] Furthermore, the positioning plate has an arc-shaped extension structure with its concave surface facing the direction of disassembling the shoe last assembly. The positioning plate is made of soft iron, and each electromagnet is attached to the upper side of the positioning plate, with the same magnetic poles formed at the contact points between each electromagnet and the positioning plate.

[0012] Furthermore, it also includes a shoe upper storage basket, a shoe sole storage basket, and a lateral movement mechanism. The shoe upper storage basket is located on one side of the conveyor belt, and the shoe sole storage basket is located at the end of the conveyor belt. The first lifting drive and the second lifting drive are mounted on the lateral movement mechanism and are driven by the lateral movement mechanism to move above the conveyor belt and the shoe upper storage basket.

[0013] Furthermore, it also includes a visual monitoring device and a control device. The visual monitoring device includes several sets of cameras, each camera being distributed on both sides of the conveyor belt. The control device connects to and controls the visual monitoring device, the conveyor belt, the positioning device, the robotic arm, and the three movable shoe lasts.

[0014] Furthermore, the positioning device also includes a support platform and guide rails. The drive cylinder is mounted on the support platform, and there are two sets of guide rails. The two sets of guide rails are parallel to each other on the support platform and located on both sides of the drive cylinder. The guide rails are equipped with sliders that can move along the guide rails, and the sliders are connected to push plates.

[0015] A method for separating the upper and sole of discarded shoes, characterized in that: based on any one of the above-mentioned devices for separating the upper and sole of discarded shoes, the method includes the following steps:

[0016] Step 1: The waste shoe material is placed on the conveyor belt and transported to the positioning device. The drive cylinders on both sides push out, and the push plate moves from both sides toward the waste shoe material. The positioning pins of the clamping plates on both sides are inserted into the sole and form a positioning.

[0017] Step two: The toe block, mid-section block, and heel block of the three-section shoe last rotate at an angle and cooperate with the first lifting drive action to allow the toe block to be inserted through the shoe opening and finally placed into the waste shoe material of the three-section shoe last. The second lifting cylinder drives the positioning plate to descend, so that the shoe upper is between the positioning plate and the three-section shoe last, and the electromagnet works to form a clamping force on the shoe upper. The first lifting drive and the second lifting drive lift, and the shoe upper is lifted upward. Since the sole is positioned, the shoe upper will be pulled and separated from the sole.

[0018] Step 3: The lateral movement mechanism moves the disassembled shoe uppers above the shoe upper storage basket. The electromagnet stops working, and the first lifting drive and the three-stage shoe last movement cause the shoe uppers to fall into the storage basket.

[0019] Step four: The lateral movement mechanism moves back to above the conveyor belt, the first lifting drive descends to the three-section movable shoe last pressing the sole for positioning, the cylinders on both sides of the positioning device retract, the positioning pin is pulled out from the sole, and then the first lifting drive descends, the conveyor belt sends the sole to the end and it falls into the sole storage basket.

[0020] As can be seen from the above description of the present invention, compared with the prior art, the device and method for separating the upper and lower surfaces of discarded shoes provided by the present invention have the following beneficial effects:

[0021] First, the upper and sole of the discarded shoe materials are disassembled as two main parts. Compared with the traditional recycling method of completely crushing the discarded shoe materials and then screening the fragments, the recycling efficiency is higher. After disassembly, the sole and upper are collected separately in two boxes. The overall state of the sole and upper makes it easier to screen them again later, achieving more efficient recycling.

[0022] The positioning device clamps the waste shoe material soles from both sides while positioning pins are inserted into the soles, thus firmly positioning the soles in the vertical direction. The structure is simple and reliable.

[0023] The three-section movable shoe last allows for controllable angle rotation between the toe block and the mid-section block, and between the mid-section block and the heel block. Driven by the first lifting mechanism and in conjunction with a vision detection device, it can automatically adapt to various types of discarded shoe materials, allowing the three-section movable shoe last to be inserted into the shoe from the shoe opening. It has wide applicability to a wide variety of recycled discarded shoes.

[0024] The second lifting cylinder drives the positioning plate to descend, and the electromagnet works to attract the three-section movable shoe last to form a clamping force on the shoe upper to achieve positioning; the first lifting drive and the second lifting drive rise, pulling and separating the shoe sole from the shoe upper, with high separation efficiency.

[0025] Multiple sets of electromagnets correspond to the toe block, mid-section block, and heel block respectively. They serve to clamp the shoe upper and also to position the toe block, mid-section block, and heel block in a horizontal state. This can compensate for the insufficient power of the small servo motor and also protect the servo motor. The second lifting drive can apply greater force to pull and separate the shoe sole and upper. The combination of the two mechanisms takes into account both strength and flexibility.

[0037] A device for separating the upper and sole of discarded shoes is applied to an automated production line for separating the upper and sole of discarded shoe materials. The following is a detailed description using an overall automated production line as an example.

[0040] The three-section movable shoe last 5 includes a toe block 51, a mid-section block 52, a heel block 53, several connectors 54, and several servo motors 55. The toe block 51, mid-section block 52, and heel block 53 have hollow structures. The connectors 54 are located between the toe block 51 and the mid-section block 52, and between the mid-section block 52 and the heel block 53. Each end of the connector 54 is connected to a servo motor 55, and the servo motors 55 are placed in the hollow structures of the toe block 51, mid-section block 52, and heel block 53, so that the toe block 51 and the mid-section block 52, and between the mid-section block 52 and the heel block 53 can rotate at a controllable angle. The three-section movable shoe last 5 is divided into a spray-painted shoe last group 5a and a disassembled shoe last group 5b.

Several clamping plates 65 are provided, and adjacent clamping plates 65 are rotatably connected. The clamping plates 65 are connected to the push plate 63 through the springs 64. The drive cylinders 62 drive the push plate 63 to move. Two sets of guide rails 66 located on both sides of the drive cylinders 62 and arranged in parallel are provided on one support platform 61. A slider 67 that can move along the guide rail 66 is provided on the guide rail 66. The slider 67 is connected to the push plate 63. The positioning device 6 includes a spray positioning group 6a and a disassembly positioning group 6b.

The lower edges of the toe block 51, mid section block 52, and heel block 53 of the spraying shoe last assembly 5a are provided with chamfered portions. Several ultrasonic atomizing heads 57 are provided and located at the chamfered portions of the toe block 51, mid section block 52, and heel block 53, forming an inclined downward spraying state. The degumming agent delivery hose 58 is connected to each ultrasonic atomizing head 57, and the degumming agent is atomized and sprayed out by the ultrasonic atomizing head 57.

[0043] The disassembly device 3 includes a first lifting drive 31, a second lifting drive 32, and a positioning plate 33. The disassembly shoe last assembly 5a is installed on the first lifting drive 31, and the outer shell of the disassembly shoe last assembly 5b is made of magnetic material. The positioning plate 33 is installed on the second lifting drive 32 and is located above the disassembly shoe last assembly 5b. The positioning plate 33 is provided with several electromagnets 34. When the electromagnets 34 are energized, a clamping and adsorption force is formed between the positioning plate 33 and the disassembly shoe last assembly 5b. Specifically, the positioning plate 33 is provided with three sets of electromagnets 34, which are respectively located on the upper side of the toe block 51, the mid-section block 52, and the heel block 53 in a horizontal position for corresponding adsorption. The positioning plate 33 has an arc-shaped extension structure with its concave surface facing the direction of the disassembly shoe last assembly 5b. The positioning plate 33 is made of soft iron, which has the characteristics of being easily magnetized and easily demagnetized. Each electromagnet 34 is attached to the upper side of the positioning plate 33, and the magnetic poles formed at the contact points between each electromagnet 34 and the positioning plate 33 are the same. The disassembly positioning assembly 6b also includes several positioning pins 68, each of which is located on the clamping plate 65 and extends outward. The positioning pins 68 on the two clamping plates 65 are arranged facing each other.

The first lifting drive 31 and the second lifting drive 32 are mounted on the transverse movement mechanism 35 and are driven by the transverse movement mechanism 35 to move above the conveyor belt 4 and the shoe upper storage basket 8.

[0045] The visual inspection device 7 has two sets, which are respectively located at the spraying device 1 and the disassembly device 3. The visual inspection device 7 includes several sets of cameras 71, which are distributed on both sides of the conveyor belt 4 and are specifically installed on the support platform 61 of the positioning device 6.

[0046] The control device connects to and coordinates the control of the spraying device 1, heating device 2, disassembly device 3, conveyor belt 4, three-section movable shoe last 5, positioning device 6, and visual monitoring device 7.

[0047] A method for disassembling shoe uppers and soles from discarded shoe materials includes the following steps:

[0048] Step 1: Waste shoe materials are placed on conveyor belt 4 for conveying. When the vision detection device 7 determines that a piece of waste shoe material has reached the set position of the spraying device 1, the conveyor belt 4 stops running, the spraying positioning group 6a starts working, the drive cylinders 62 on both sides push out, and the push plate 63 moves from both sides toward the waste shoe material. When the clamping plate 65 is close to the side of the waste shoe material, due to the rotational connection structure between adjacent clamping plates 65, each clamping plate 65 adaptably rotates to fit the side of the waste shoe material, which can accommodate waste shoe materials of different sizes. The pushing force of the push plate 63 is transmitted to each clamping plate 65 through the spring 64 to form a uniform clamping force on both sides of the waste shoe material.

[0049] Step two: The robotic arm 11 drives the spray-painted shoe last assembly 5a to move. The vision detection device 7 provides visual information to the controller, which controls each servo motor 55 to rotate the toe block 51, mid-section block 52, and heel block 53 at the passing angle. Simultaneously, in coordination with the robotic arm 11, the toe block 51 is inserted through the shoe opening and finally placed into the waste shoe material in the spray-painted shoe last assembly 5a. Each ultrasonic atomizing head 57 operates, and the atomized adhesive remover is sprayed out from inside the waste shoe. Since the ultrasonic atomizing heads 57 are located at the chamfered corners of the toe block 51, mid-section block 52, and heel block 53... Therefore, the sprayed atomized adhesive remover is directed towards the edges of the upper and sole. The atomized spray ensures uniformity of the adhesive remover and also has higher penetration, allowing it to more easily pass through the upper fabric and reach the glued areas on the upper and sole. The purpose of spraying the adhesive remover inside the shoe is that the outer surface of athletic shoes and other shoes is usually made of leather, which has a certain degree of water resistance, making it difficult for the adhesive remover to penetrate. However, the inner material of the shoe is usually breathable fabric. Spraying the adhesive remover inside the shoe ensures effective utilization of the adhesive remover and makes it easier for it to reach the bonding area between the sole and the upper.

[0050] Step 3: The visual inspection device 7 provides visual information to the controller, which controls each servo motor 55 to rotate the toe block 51, mid-section block 52, and heel block 53 at the passing angle. At the same time, the robotic arm 11 moves to remove the sprayed shoe last assembly 5a from the waste shoe material. The drive cylinders 62 on both sides of the sprayed positioning assembly 6a retract, the conveyor belt 4 resumes operation, and the waste shoe material is transported on the conveyor belt 4 again and enters the heating device 2. The high temperature environment in the heating device 2 accelerates the reaction of the adhesive, causing the glued joint between the shoe upper and the sole of the waste shoe material to loosen.

[0051] Step four: As the conveyor belt 4 transports the material, when the visual inspection device 7 determines that a piece of waste shoe material has reached the set position of the dismantling device 3, the conveyor belt 4 stops running, the dismantling positioning group 6b starts working, the drive cylinders 62 on both sides push out, the push plate 63 moves from both sides toward the waste shoe material, and the positioning pins 68 of the clamping plates 65 on both sides insert into the sole and form a position.

[0052] Step 5: The visual inspection device 7 provides visual information to the controller, causing the servo motors 55 within the disassembled shoe last assembly 5b to operate, resulting in angular rotation between the toe block 51, mid-section block 52, and heel block 53. Simultaneously, in conjunction with the lifting action of the first lifting drive 31, the toe block 51 is inserted through the shoe opening and finally placed into the discarded shoe material within the disassembled shoe last assembly 5b. At this point, the toe block 51, mid-section block 52, and heel block 53 within the discarded shoe material are in a horizontal position. The second lifting drive 32 descends, driving the positioning plate 33 to... The shoe upper is pressed between the positioning plate 33 and the disassembled shoe last assembly 5b. The three electromagnets 34 on the positioning plate 33 are respectively positioned above the toe block 51, the mid-section block 52, and the heel block 53. After the electromagnets 34 are energized, they are attracted to form a tight clamping force on the shoe upper. The attraction of the three electromagnets 34 to the toe block 51, the mid-section block 52, and the heel block 53 also provides the force to keep the toe block 51, the mid-section block 52, and the heel block 53 in a horizontal position, and also plays a role in protecting the servo motor 55 inside the three movable shoe lasts 5.

[0053] Step six: The first lifting drive 31 and the second lifting drive 32 lift, and the shoe upper is lifted upward by being clamped. Since the sole is fixed by the positioning pin 68, the shoe upper will be pulled and separated from the sole. The lateral movement mechanism 35 works to move the separated shoe upper to above the shoe upper storage basket 8. The electromagnet 34 stops working, and the first lifting drive 31 and the disassembly shoe last assembly 5b move to make the shoe upper fall into the shoe upper storage basket 9.

[0054] Step seven: The lateral movement mechanism 35 moves back above the conveyor belt 4, the first lifting drive 31 descends to press down on the shoe sole positioning assembly 5b, the cylinders on both sides of the positioning device 6 retract, the positioning pin 68 is pulled out from the shoe sole, and then the first lifting drive 31 rises, the conveyor belt 4 resumes operation, and the conveyor belt 4 delivers the disassembled shoe sole to the end where it falls into the shoe sole storage basket 9. The overall state of the shoe sole and upper facilitates subsequent screening, achieving more efficient recycling.

[0055] The above is only one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing the protection scope of the present invention.
