Description

Technical Field

[0001] This invention relates to the field of resource recycling, and in particular to a method and equipment for disassembling shoe bodies. Background Technology

[0002] With the rise of global athleisure and the rapid iteration of the consumer market, the annual output of footwear has exceeded 20 billion pairs. However, because the shoe body is typically composed of various heterogeneous materials such as rubber, foam, textiles, leather, and thermoplastic elastomers bonded together with adhesives, its structure is extremely complex. As a result, only about 5% of discarded shoes can currently be recycled and reused through existing channels. The vast majority of the remaining discarded shoes end up in landfills or are incinerated, which not only occupies a large amount of land resources and releases toxic and harmful gases, but also causes serious environmental pollution and wastes valuable petroleum-based resources.

[0003] In existing recycling technologies, the dismantling of discarded shoe uppers mainly relies on manual, forceful dismantling or complete crushing. While manual dismantling can achieve a certain degree of material sorting, it is extremely inefficient and highly dependent on labor costs, making it completely unsuitable for industrial-scale production. Complete crushing, on the other hand, mixes components of different materials together, resulting in extremely low-purity recycled materials that can only be used as low-value fillers, failing to achieve true high-value recycling. Furthermore, while some chemical debinding methods can separate materials, they often require large amounts of organic solvents, easily causing secondary pollution and causing high equipment corrosivity. Therefore, how to provide an efficient, environmentally friendly shoe upper dismantling technology suitable for industrial-scale production, capable of accurately separating shoe components and restoring the original material properties, has become a pressing technical challenge in the field of resource recycling. Summary of the Invention

[0004] The purpose of this invention is to provide a shoe disassembly method and disassembly equipment, which achieves the goal of precise material separation and recycling through efficient, environmentally friendly shoe disassembly technology suitable for industrial mass production.

[0005] To achieve the above-mentioned technical objectives and effects, this invention discloses a method for disassembling a shoe body, wherein the shoe body is bonded together with the sole, midsole, and upper using at least one adhesive. The disassembly method includes at least the following steps: S1. The shoe body is modified by altering the adhesive's physical properties in a modified environment, causing the adhesive to lose its adhesive properties; S2. Remove the sole from the shoe body; S3. The midsole is removed from the shoe body, thereby separating the shoe body into the sole, the midsole, and the upper. S4. Collect the sole, midsole, and upper of the shoe one by one.

[0006] The present invention also discloses a shoe disassembly device. The shoe disassembly device is based on the above-mentioned shoe disassembly method and includes at least a circulating conveying device and a peeling device. The circulating conveying device is provided with multiple shoe lasts at equal intervals. The shoe body to be disassembled is sequentially placed on each of the shoe lasts, and the shoe body is passed through a pretreatment device with a modified environment by the circulating conveying device to make the adhesive between the shoe bodies lose its adhesive properties. Finally, the sole, midsole and upper of the shoe body are sequentially peeled and separated by the peeling device.

[0007] In some embodiments, the peeling device includes at least three peeling clamps corresponding to the shoe body structure and three collection buckets. The peeling clamps peel off and separate the sole, midsole and upper of the shoe body in sequence as the shoe last passes by, and place them into the corresponding collection buckets respectively.

[0008] In some embodiments, the peeling device includes at least three peeling roller groups corresponding to the shoe body structure and three collection buckets. The peeling roller groups are disposed below the circulating conveying device, and each peeling roller group has at least one roller. When the shoe last is conveyed through the peeling roller groups, the bottom of the shoe body is peeled off and separated in sequence by the contact friction of the rollers with the bottom of the shoe body, and the sole, midsole and upper of the shoe body fall into the corresponding collection buckets respectively.

[0009] In some embodiments, the peeling device also provides a follow-up peeling roller group below the peeling roller group. The follow-up peeling roller group has two rollers arranged vertically and intersecting each other, and a longitudinal channel is formed between the two rollers. This allows the shoe body, which has been rubbed by the peeling roller group but has not yet been completely separated, to continue the shoe body separation operation by passing through the follow-up peeling roller group.

[0010] This invention also discloses a shoe disassembly device, which is based on the aforementioned shoe disassembly method and includes a rotary conveyor, a peeling cylinder, and a conveyor belt. The rotary conveyor has a rotating shaft and multiple shoe lasts equidistantly arranged on the rotating shaft. The shoe bodies to be disassembled are sequentially placed on each of the shoe lasts, and the rotary conveyor passes each shoe body through a pretreatment device with a modified environment to cause the adhesive between the shoe bodies to lose its adhesive properties. The peeling cylinder has conical channels with gradually narrowing inner diameters at both ends, and the conical channels have a function of releasing... The rotary conveyor device, with its inlet and outlet, gradually inserts multiple shoe bodies into the conical channel through the inlet. Utilizing the tapered design of the conical channel, the bottoms of each shoe body gradually come into contact with and rub against the inner wall of the channel. Simultaneously, the peeling friction generated by the rotation of the rotating shaft peels off the soles and midsoles, and removes the uppers from the shoe last. Finally, the shoes are discharged through the outlet. A conveyor belt is positioned below the outlet of the peeling cylinder to receive, transport, and classify the peeled soles, midsoles, and uppers.

[0011] The present invention also discloses a method for disassembling a shoe body, wherein the shoe body is bonded together with the sole, midsole, and upper using at least one adhesive, and the disassembly method includes at least the following steps: S1. The shoe body is modified by altering the adhesive's physical properties in a modified environment, causing the adhesive to lose its adhesive properties; S2. Use an extrusion method to separate the sole, midsole, and upper, which have lost their adhesive properties; S3. Further compression and destruction to form fragments, thereby obtaining scrap material; S4. Collect the scraps one by one.

[0012] This invention also discloses a shoe disassembly device, which is based on the above-mentioned shoe disassembly method and includes at least a spiral disassembly device and a conveyor belt. The spiral disassembly device has a shoe material barrel and a disassembly screw centrally disposed within the shoe material barrel. The shoe material barrel has a heating function, thereby creating a modified environment inside the shoe material barrel that can change the properties of the adhesive. One end of the shoe material barrel forms an inlet and the other end forms a outlet. The disassembly screw has blades with a continuous thread design, and the outer edge of the blades is connected to the shoe material barrel. The inner wall is not in contact with the material and has a gap; the shoe body to be disassembled is put into the shoe material barrel through the inlet. The internal heating temperature causes the adhesive between the shoe bodies to lose its adhesive properties. Then, it falls into the gap and is crushed and peeled and fragmented by the extrusion of the blade and the inner wall. Finally, the broken pieces of the sole, midsole and upper are moved along the blade towards the discharge port. The conveyor belt is connected below the discharge port to receive and transport the broken pieces of the shoe body.

[0013] In some embodiments, the dismantling equipment further includes a blowing and sorting device, which includes multiple fans disposed on the side of the conveyor belt and multiple collection bins for collecting debris. By utilizing the differences in the weight of the debris, the debris is blown with different air volumes during transportation to perform collection and sorting operations.

[0014] This invention also discloses a shoe disassembly device. The shoe disassembly device is based on the above-mentioned shoe disassembly method and includes at least a compression device. The compression device includes a compression groove and a compression head that moves up and down to compress the compression groove. The compression groove has a heating function, thereby creating a modified environment inside the compression groove that can change the physical properties of the adhesive. The shoe body to be disassembled is placed in the compression groove. Through the internal heating temperature, the adhesive between the shoe bodies loses its adhesive properties. Then, the compression head is moved towards the compression groove and compresses the shoe body, causing the shoe body to be broken, peeled off, and fragmented.

[0015] In some embodiments, the extrusion groove of the extrusion device is provided with at least one crushing shaft. The crushing shaft is used to simultaneously crush the shoe body when it is pushed down by the extrusion head, so as to achieve the purpose of destroying, peeling off and fragmenting the shoe body.

[0016] The present invention has the following beneficial effects: 1. This invention provides a variety of modified environments that alter the properties of the adhesive, causing the adhesive between different parts of the shoe to completely lose its stickiness, thereby significantly reducing the resistance to mechanical separation. At the same time, in conjunction with a variety of automated disassembly equipment such as a circulating conveyor peeling device, a rotating peeling cylinder, and a spiral crushing device, it achieves high-precision and high-efficiency separation of the sole, midsole, and upper, completely replacing traditional manual operations, significantly reducing the manpower required and production costs in the disassembly process, and greatly improving overall operational efficiency.

[0017] 2. Through reasonable design, this invention classifies and recycles the disassembled soles, midsoles, and uppers into complete parts or regular fragments according to recycling needs, effectively avoiding the mixing of different polymer materials, thereby significantly improving the purity, quality, and reuse value of the recycled materials; at the same time, it reduces the environmental impact of shoe waste, truly achieving the goal of promoting the development of a circular economy.

Detailed Implementation

[0032] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Example 1

[0033] To make the design intent of this invention easier to understand, this section further explains the invention in conjunction with the accompanying drawings: First, please combine Figure 1As shown, a shoe disassembly method includes at least one shoe body 10, wherein the shoe body 10 is bonded together with a sole 11, a midsole 12, and an upper 13 by at least one adhesive. The disassembly method is used to preserve the complete shape of the sole 11, midsole 12, and upper 13 in an application scenario, and includes at least the following steps: S1. Pass the shoe body 10 through a modified environment 100 that can change the properties of the adhesive, so that the adhesive loses its adhesive properties; S2. Remove the sole 11 from the shoe body 10; S3. Remove the midsole 12 from the shoe body 10, thereby separating the shoe body 10 into the sole 11, the midsole 12, and the upper 13; S4. Collect the sole 11, midsole 12, and upper 13 one by one.

[0034] Based on the above disassembly methods, a shoe disassembly device is proposed, combining... Figures 2-4 As shown, the shoe disassembly equipment includes a circulating conveyor 20 and a stripping device 30. The circulating conveyor 20 can be a ring-shaped chain conveyor belt, with a total length of approximately 12 to 20 meters. Multiple shoe lasts 21 are equidistantly arranged on the circulating conveyor 20. The shoe lasts 21 are made of aluminum alloy and can hold shoe bodies from US4 to US13. The shoe bodies 10 to be disassembled are sequentially placed on each of the shoe lasts 21, and then transported by the circulating conveyor 20 through a modified environment 100. The pretreatment device 22 can be a heating chamber with temperature modification effect, having an adjustable temperature of 80℃ to 300℃, or a freezing chamber with an adjustable temperature of -60℃ to -80℃. This causes the adhesive between the layers of the shoe body 10 to lose its adhesive properties due to temperature influence in the modified environment 100. Finally, the mechanical force of the peeling device 30 is used to peel off and separate the sole 11, midsole 12, and upper 13 of the shoe body 10 in sequence.

[0035] The pretreatment device 22 of the modified environment 100 described above, which uses a hot drying chamber and a freezing chamber with temperature parameter adjustment as a method for modifying the adhesive, is only a preferred embodiment and should not be considered as a limitation. Other feasible methods are described below: 1. The adhesive between the composite materials of the shoe body is destroyed by a high-voltage electric discharge chamber; 2. Accelerate adhesive disintegration through a high humidity and high temperature environment; 3. By using electromagnetic waves and radiation to degrade or heat the material, or by destroying the molecular structure, the adhesive between the shoe parts loses its stickiness; 4. The adhesive is destroyed by UV light and microwave heating; 5. Effectively disrupts the bonds in the shoe adhesive through a supercritical state; 6. By using ultrasound, high-frequency vibration, and heat energy, the adhesive structure of the shoe body is destroyed, causing it to lose its adhesiveness; 7. Add a low-temperature penetrant (such as a de-adhesive, acetone) or surfactant to the shoe body to make the adhesive between the layers of the shoe body 10 lose its stickiness; the above methods can effectively achieve the purpose of modifying or destroying the adhesive, thereby making the adhesive lose its stickiness so as to facilitate the disassembly of the shoe body 10.

[0036] In one preferred embodiment of the aforementioned peeling device 30, the peeling device 30, corresponding to the structure of the shoe body 10, includes at least three peeling clamps 31, 31a, and 31b and three corresponding collection bins 32, 32a, and 32b. The first peeling clamp 31 performs the peeling operation on the sole 11 of the shoe body 10, with a clamping force set to 150 to 200 N, clamping at the outer edge of the sole 11, and peeling the sole 11 horizontally from the midsole 12. The second peeling clamp 31a performs the peeling operation on the midsole 12, with a clamping force set to 80 to 120 N, and... The midsole 12 is detached from the bottom of the upper 13. The third detachment clamp 31b performs the detachment operation on the upper 13. After the sole 11 and the midsole 12 are removed, the shoe last 21 continues to be operated by the circulating conveyor 20. The upper 13 is held by the third detachment clamp 31b and pulled out from the shoe last 21. Accordingly, the sole 11, midsole 12 and upper 13 of the shoe body 10 are detached and separated in sequence by the detachment clamps 31, 31a and 31b as the shoe last 21 passes through, and are placed into the corresponding collection buckets 32, 32a and 32b respectively to complete the classified collection.

[0037] Another preferred embodiment of the aforementioned stripping device 30, combined with Figure 5 As shown, the peeling device 30, corresponding to the structure of the shoe body 10, has at least three peeling roller groups 33, 33a, and 33b and three collection bins 34, 34a, and 34b. The peeling roller groups 33, 33a, and 33b are located below the circulating conveying device 20, and each peeling roller group 33, 33a, and 33b has at least one roller, while the first peeling roller group 33 and the second peeling roller group 33a may each have two rollers. Each set of rollers has a diameter of 120mm, and the outer surface of the rollers is covered with... The shoe is covered with an outer layer that increases friction. The tangential speed generated by the rotational speed of the peeling rollers 33, 33a, and 33b and the speed difference of the circulating conveyor 20 generate peeling friction. Accordingly, when the shoe last 21 is conveyed through the peeling rollers 33, 33a, and 33b, the rollers contact and rub against the bottom of the shoe body 10, thereby peeling off and separating the sole 11, midsole 12, and upper 13 of the shoe body 10 in sequence, and they fall into the corresponding collection buckets 34, 34a, and 34b respectively.

[0038] Furthermore, considering the differences in shape, volume, and adhesive of various shoe bodies 10, some shoe bodies 10 may simultaneously peel the sole 11 and midsole 12 from the upper 13, or pull the entire shoe body 10 out of the shoe last 21 when passing through the first two peeling roller groups 33, resulting in inaccurate peeling and separation operations. Therefore, the aforementioned peeling device 30 further provides a successor peeling roller group 35 below at least one of the peeling roller groups 33. Please refer to... Figure 6 As shown, the continuous peeling roller assembly 35 has two rollers arranged vertically and intersecting each other, and a longitudinal channel 351 is formed between the two rollers. This allows the shoe body 10, which has been rubbed by the peeling roller assembly 33 but has not yet been completely separated, to pass through the longitudinal channel 351 of the continuous peeling roller assembly 35 and be subjected to longitudinal friction and pressure from the two rollers to continue the peeling and separation operation of the shoe body 10, ensuring the complete disassembly of the shoe body 10.

[0039] Another preferred embodiment of the above disassembly method, combined with Figure 7 , Figure 8 As shown, the disassembly method includes a rotary conveyor 40, a peeling cylinder 41, and a conveyor belt 42. The rotary conveyor 40 has a rotating shaft 401 and multiple shoe lasts 402 equidistantly arranged on the rotating shaft 401. The shoe bodies 10 to be disassembled are sequentially placed on each of the shoe lasts 402, and the rotary conveyor 40 passes each shoe body 10 through a pretreatment device (not shown in the figure) with the modified environment, causing the adhesive between the shoe bodies 10 to lose its adhesive properties. The peeling cylinder 41 has conical channels 411 with gradually narrowing inner diameters at both ends. The conical channels 411 have an inlet 412 and an outlet 413, and the inner wall surface of the conical channels 411 can be sandblasted to improve the adhesion. To enhance friction, the rotary conveyor 40 gradually inserts multiple shoe bodies 10 into the conical channel 411 through the inlet 412. Utilizing the tapered design of the conical channel 411, the bottoms of each shoe body 10 gradually come into contact with and rub against the inner wall of the conical channel 411. Simultaneously, the mechanical force and peeling friction generated by the rotation of the rotating shaft 401 allow the sole 11 and midsole 12 to be peeled and separated, while the upper 13 is carried away from the shoe last 402 and finally discharged through the outlet 413. The conveyor belt 42 is located below the outlet 413 of the peeling cylinder 41 to receive and transport the peeled and separated sole 11, midsole 12, and upper 13 for sorting and collection. Example 2

[0040] This embodiment, based on Embodiment 1, proposes different dismantling methods for different types of recycled shoe bodies. For example, it includes a shoe body dismantling method applicable to shoes in poor condition where the primary purpose is to obtain scrap materials. Figure 9As shown, the shoe includes at least one shoe body 10, which is bonded together with the sole 11, midsole 12, and upper 13 by at least one adhesive. The disassembly method includes at least the following steps: S1. Pass the shoe body 10 through a modified environment 100 that can change the properties of the adhesive, so that the adhesive loses its adhesive properties; S2. Use a squeezing method to separate the sole 11, midsole 12 and upper 13, which have lost their adhesive properties; S3. Further compression and destruction to form fragments, thereby obtaining scrap material; S4. Collect the scraps one by one.

[0041] Based on the above disassembly methods, a shoe disassembly device is proposed, combining... Figure 10 As shown, the shoe disassembly equipment includes a spiral disassembly device 50 and a conveyor belt 51. The spiral disassembly device 50 has a shoe material barrel 52 and a disassembly screw 53 centrally located inside the shoe material barrel 52. The shoe material barrel 52 has a heating function, thereby creating a modified environment 100 inside the shoe material barrel 52 that can change the properties of the adhesive. One end of the shoe material barrel 52 forms an inlet 521, and the other end forms a outlet 522. The inner wall surface of the shoe material barrel 52 can be sandblasted to improve the friction effect. The disassembly screw 53 has blades 531 with a continuous thread design. The outer edge of the blades 531 does not contact the inner wall of the shoe material barrel 52. The shoe body 10 is placed into the shoe material barrel 52 through the inlet 521, and the adhesive between the shoe bodies 10 loses its adhesive properties due to the internal heating temperature. Then, the disassembly screw 53 is activated, and the shoe body 10 is trapped in the gap 54. The blade 531 and the inner wall squeeze the shoe body 10 to produce a destructive peeling and fragmentation effect. Finally, the broken pieces of the sole 11, the midsole 12 and the upper 13 are moved along the blade 531 towards the discharge port 522. The conveyor belt 51 is connected below the discharge port 522 to receive and transport the broken pieces of the shoe body 10. Furthermore, the fragment dismantling method further includes a blowing and sorting device 55, which has multiple fans 551 facing the side of the conveyor belt 51 and multiple collection bins 552 for collecting fragments. By utilizing the difference in the weight of the fragments, the fragments are blown with different air volumes during transportation and fall into the corresponding collection bins 552 for collection and sorting.

[0042] Another preferred embodiment of the above disassembly method, combined with Figure 11As shown, it includes an extrusion device 60, which includes an extrusion groove 61 and an extrusion head 62 that moves up and down to extrude the extrusion groove 61. The extrusion groove 61 has a heating function, thereby creating a modified environment 100 inside the extrusion groove 61 that can change the properties of the adhesive. Accordingly, the shoe body 10 to be disassembled is placed in the extrusion groove 61. Through the internal heating temperature, the adhesive between the shoe bodies 10 loses its adhesive properties. Then, the extrusion device 60 is activated, causing the extrusion head 62 to move towards the extrusion groove 61 and extrude the shoe body 10, resulting in the shoe body 10 being broken, peeled off, and fragmented. Figure 12 As shown, the extrusion groove 61 of the extrusion device 60 is provided with at least one crushing shaft 63. The crushing shaft 63 is provided with helical teeth. When the extrusion head 62 presses down, the crushing shaft 63 is started to rotate simultaneously. The crushing shaft 63 is used to crush the shoe body 10 at the same time when it is pushed down by the extrusion head 62, so that the shoe body 10 is simultaneously torn and cut, achieving a more uniform fragmentation effect and achieving the purpose of shoe body destruction, peeling and fragmentation.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.

The conveyor belt is connected below the outlet to receive and transport the broken fragments of the shoe body.

9. The shoe disassembly device as described in claim 8, characterized in that, The dismantling equipment also includes a blowing and sorting device, which includes multiple fans and multiple collection bins for collecting debris, located on the side of the conveyor belt. By utilizing the differences in the weight of the debris, the debris is blown with different air volumes during transportation to collect and sort it.

10. A shoe disassembly device, characterized in that, The shoe disassembly equipment, based on the shoe disassembly method of claim 7, includes at least a compression device. The compression device includes a compression groove and a compression head that lifts and presses against the compression groove. The compression groove has a heating function, thereby creating a modified environment inside the compression groove that can change the physical properties of the adhesive. The shoe body to be disassembled is placed in the compression groove, and the adhesive between the shoe bodies loses its adhesive properties through the internal heating temperature. Then, the compression head is moved towards the compression groove and squeezes the shoe body, causing the shoe body to be destroyed, peeled off, and fragmented.

11. The shoe disassembly device as described in claim 10, characterized in that, The extrusion device has at least one crushing shaft inside the extrusion groove. The crushing shaft is used to simultaneously crush the shoe body when it is pushed down by the extrusion head, so as to achieve the purpose of destroying, peeling and fragmenting the shoe body.
