Description

Technical Field

[0001] The present application relates to the technical field of material equipment, and in particular to an automatic tray disassembly machine. Background Art

[0002] In the logistics and warehousing fields, pallets serve as essential tools for loading and transporting goods. When not in use, pallets are typically stacked to form pallet stacks to save storage space. When in use, pallet depalletizers are used to separate the stacked pallets and transport them to designated locations for subsequent loading and unloading. In related technologies, a pallet unpacking machine primarily consists of a clamping mechanism and a conveyor mechanism. The clamping mechanism is located above the conveyor mechanism and can move up and down. During operation, after a pallet stack is placed onto the conveyor mechanism, the clamping mechanism grips the remaining pallets in the stack, excluding the bottom pallet, and moves them upward. The bottom pallet automatically detaches from the stack due to gravity. After the conveyor mechanism transfers the bottom pallet, the clamping mechanism then drives the remaining pallets in the stack downward, placing the bottom pallet on the conveyor mechanism. This process is repeated to gradually complete the unpacking and transfer of the pallets. like Figure 1 Currently, the main types of pallets 1 include wooden pallets 1 and plastic pallets 1. Among them, the legs 11 of the plastic pallets 1 are hollow inside and open at the top. When stacked, the legs 11 of the upper plastic pallet 1 can be stored in the inner cavity of the legs 11 of the lower plastic pallet 1.

[0003] Regarding the above-mentioned related technologies, when plastic pallets are stacked and stored, as the number of pallet stacks increases, the lower pallets are squeezed by the gravity of the upper part, and the legs of adjacent pallets will fit tightly together, resulting in the adjacent pallets being unable to separate by their own weight when the pallets are subsequently disassembled. Existing pallet disassembly machines are usually unable to normally disassemble this type of plastic pallet; therefore, there is room for improvement. Summary of the Invention

[0004] In order to make the pallet depalletizer more compatible with the depalletizing and conveying of wooden pallets and plastic pallets, the present application provides an automatic pallet depalletizer.

[0005] The present application provides an automatic disk disassembly machine, which adopts the following technical solution: An automatic tray disassembly machine includes a frame, a tray disassembly mechanism, a limiting mechanism and a conveying mechanism One side of the frame is open to form a loading side, and a tray removal station is provided at the bottom of the frame; The tray dismantling mechanism is located at the tray dismantling station, and the tray dismantling mechanism includes a supporting plate, a lifting drive and a tray dismantling clamping assembly; the supporting plate is used to lift the tray; the lifting drive is used to drive the supporting plate to rise and fall vertically; the tray dismantling clamping assembly includes two tray dismantling clamping parts, which are respectively located at both ends of the supporting plate, and the two tray dismantling clamping parts are used to cooperate with clamping the tray; The limiting mechanism includes two limiting components arranged on the frame, and the two limiting components are used to cooperate to limit the tray; The conveying mechanism is located below the disassembling station and includes two conveyor belts, the input ends of the two conveyor belts are arranged on both sides of the supporting plate; When the tray is located on the supporting plate, two sides of the tray extend out from two sides of the supporting plate respectively; and the protruding portion of the tray is arranged opposite to the conveyor belt.

[0006] By adopting the above technical solution, when dismantling wooden pallets, the pallet stack is moved into the rack through the loading side of the rack and placed on the supporting plate. The two limiting components of the limiting mechanism are first used to limit the second-to-last pallet in the pallet stack. Then, the lifting drive drives the supporting plate to drive the penultimate pallet to move down until the pallet extends out of the two sides of the supporting plate and is respectively overlapped on the two conveyor belts of the conveying mechanism, and the pallet is transferred out by the two conveyor belts. When dismantling plastic pallets, the pallet stack is moved into the rack through the loading side of the rack and placed on the supporting plate. The two limiting components of the limiting mechanism are first used to cooperate with the second-to-last pallet in the pallet stack. The pallet is then moved downwards by the lifting drive component, until the pallet extends out of the two sides of the support plate and is respectively connected to the two conveyor belts of the conveying mechanism, and the pallet is transferred out by the two conveyor belts; when the plastic pallet is being removed, the pallet is clamped and limited by the two removal clamping components, so that when the support plate moves downwards, the pallet can be smoothly removed, and the situation that the pallet cannot be smoothly removed due to the adjacent pallet legs being too tightly clamped is effectively avoided, so that the automatic pallet removal machine can be adapted to various types of pallets for removal.

[0007] The bottom pallet is transported out by two conveyor belts located below the depalletizing station, realizing the depalletizing of wooden pallets. As for plastic pallets, since their legs are hollow inside and the upper and lower legs fit tightly together, while the limit assembly clamps the second-to-last pallet, the two depalletizing clamping parts of the depalletizing mechanism move relative to each other from both ends of the support plate, clamping the bottom (the penultimate) pallet. As the lifting drive drives the support plate down, the legs of the second-to-last pallet are released from the legs of the penultimate pallet, and the bottom pallet is then placed on the conveyor belt for transportation. This solves the problem of plastic pallets being difficult to detach by their own weight due to the tightly fitting legs, and allows for smooth depalletizing of plastic pallets. This design allows the automatic depalletizing machine to handle both wooden and plastic pallets, effectively expanding the scope of application of the equipment and improving depalletizing efficiency.

[0008] Preferably, the disc removing clamping part includes a vertical cylinder, a horizontal cylinder is supported on the top of the vertical cylinder piston rod, the horizontal cylinders of the two disc removing clamping parts are arranged opposite to each other, and the horizontal cylinder piston rods are connected to the disc removing splints.

[0009] By adopting the above technical solution, when the plastic pallet is clamped and limited by the cooperation of the two pallet removal clamping parts, the vertical cylinder first drives the horizontal cylinder to drive the pallet removal clamping plate to move up, and then the transverse cylinder drives the corresponding pallet removal clamping plate to abut against the end of the plastic pallet, so that the plastic pallet can be clamped and limited, which is convenient for cooperating with the subsequent downward moving support plate to drive the pallet to smoothly escape from the bottom of the pallet stack.

[0010] Preferably, the top of the disc removal splint is bent to form a bent portion, and the bent portion is arranged away from the corresponding transverse cylinder.

[0011] By adopting the above technical solution, the two transverse cylinders drive the corresponding pallet removal splints to extend and abut against the corresponding pallet, while the bent part of the pallet removal splint extends into the gap between adjacent pallets. The bent part is used to limit the pallet removal splint, so that when the pallet is subsequently driven downward, the two pallet removal splints can more firmly drive the pallet to be removed from the pallet stack, which is beneficial to limit the situation where the pallet removal splint is detached from the pallet.

[0012] Preferably, the limiting assembly includes a limiting bracket, and the limiting bracket is provided with a first limiting portion and a second limiting portion; The first limiting portion includes a plurality of limiting rods horizontally inserted on the limiting bracket; the first limiting portion also includes a first sliding drive member, the first sliding drive member is used to drive the plurality of limiting rods to slide in the horizontal direction; The second limiting portion includes a limiting clamping plate and a second sliding driving member. The limiting clamping plates of the two limiting assemblies are arranged opposite to each other; the second sliding driving member is used to drive the corresponding limiting clamping plate to move horizontally.

[0013] By adopting the above technical solution, when limiting the position of wooden pallets, the first sliding drive components of the two limiting brackets drive several limiting rods to extend into the gap between the penultimate pallet and the penultimate pallet, and the subsequent downward movement of the supporting plate drives the penultimate pallet to move downward, and the several limiting rods are used to temporarily support and limit the pallet stack to limit the downward movement of the pallet stack, thereby facilitating the smooth splitting of the pallets; when limiting the position of plastic pallets, the second sliding drive components of the two limiting brackets drive the corresponding limiting splints to abut the penultimate pallet, and the two limiting splints are used to limit the penultimate pallet to limit the downward movement of the pallet stack, thereby facilitating the smooth splitting of the pallets.

[0014] Preferably, the frame is further provided with an auxiliary clamping mechanism, which includes two auxiliary clamping parts, which are respectively located above the two limit assemblies, and the two auxiliary clamping parts are relatively movable to cooperate in clamping the tray.

[0015] By adopting the above technical solution, when a large number of plastic pallets are stacked, the gap between adjacent pallets at the bottom of the pallet stack is reduced due to the gravity of the pallets in the upper area, which affects the extension of the bent portion of the subsequent pallet removal clamp and causes the adjacent pallet legs to fit more tightly, affecting the removal of the pallets; through the setting of the auxiliary clamping mechanism, when the plastic pallet is removed, the two auxiliary clamping parts first cooperate to clamp the pallets in the upper area of ​​the pallet stack to limit the gravity load of the upper pallet from concentrating on the lower pallet; this is conducive to alleviating the reduction of the gap between adjacent pallets due to the large number of pallets stacked and the tight connection of the pallet legs in the inner cavity of the adjacent pallet legs.

[0016] Preferably, a plurality of limit baffles are vertically installed on the inner side of the feeding side of the inner cavity of the frame.

[0017] By adopting the above technical solution, the pallet stack located in the inner cavity of the frame is circumferentially limited by the limit baffle, which is conducive to ensuring that the pallet remains stable during the pallet removal process, limiting the shaking or deviation of the pallet during the subsequent pallet removal process, and facilitating better improvement of the stability and accuracy of the pallet removal operation.

[0018] Preferably, the frame is further provided with a positioning assembly, and the positioning assembly includes a positioning baffle and a positioning portion; The positioning baffle is arranged at the bottom of the feeding side of the frame, the positioning portion is located on the side of the frame opposite to the feeding side, the positioning portion includes a positioning push plate and a positioning drive member, the positioning push plate is arranged opposite to the positioning baffle, and the positioning drive member is used to drive the positioning push plate to move toward or away from the positioning baffle; When the positioning driving member drives the positioning push plate to push the tray on the supporting plate to abut against the positioning baffle, opposite sides of the tray extend out of the opposite sides of the supporting plate respectively.

[0019] By adopting the above technical solution, the loading side of the frame lacks corresponding limits, and adjacent wooden pallets are easily stacked unevenly. When the subsequent pallet is lifted by the supporting plate, it is easy for part of the pallet to not extend outside the supporting plate, affecting the subsequent connection and transportation of the pallet by the conveying mechanism. By setting up a positioning component, when the supporting plate lifts the last pallet in the pallet stack and moves it to the positioning component, the positioning drive member drives the positioning push plate to push the pallet on the supporting plate to abut against the positioning baffle, so that the opposite sides of the pallet are evenly extended from the opposite sides of the supporting plate. This is conducive to ensuring that the subsequent pallet is accurately connected with the conveyor belt of the conveying mechanism, so that the conveying mechanism can smoothly transport the split pallets.

[0020] Preferably, guide plates are installed on both sides of the loading side of the frame, and the guide plates on both sides of the frame are turned outward.

[0021] By adopting the above technical solution, two guide plates are used to form a guide structure on the loading side of the rack, which facilitates the smooth movement of the stacked pallets into the interior of the rack.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When using a pallet disassembly machine to disassemble a plastic pallet, use the two pallet disassembly clamping components of the support plate to clamp and limit the pallet so that the pallet can be smoothly removed when the support plate moves down, avoiding the situation where the pallet cannot be smoothly removed due to the adjacent pallet legs being too tightly connected.

[0023] 2. Through the setting of the auxiliary clamping mechanism, when the plastic pallets are disassembled, the two auxiliary clamping parts first cooperate to clamp the pallets in the upper area of ​​the pallet stack, which is beneficial to separate the gravity of the pallets in the upper area of ​​the pallet stack, limit the load of the pallets in the upper area of ​​the pallet stack to act on the pallets in the lower area of ​​the pallet stack, and help to reduce the gap between adjacent pallets and ensure the tight connection of the pallet legs.

[0024] 3. Through the setting of the positioning component, when the wooden pallet is disassembled, after the pallet is connected to the supporting plate, the positioning drive component drives the positioning push plate to push the pallet on the supporting plate to abut against the positioning baffle, so that the opposite sides of the pallet are evenly extended from the opposite sides of the supporting plate, ensuring that when the supporting plate drives the pallet to move downward, the pallet can be accurately docked with the conveyor belt of the conveying mechanism.

When the plastic pallets 1 are stacked, the legs 11 of the upper pallet 1 are embedded in the inner cavity of the legs 11 of the lower pallet 1 .

[0037] The present application discloses an automatic disk disassembly machine. Figure 2 and Figure 3 , including a frame 2, a pallet removal mechanism 3, a limiting mechanism 4, a conveying mechanism 5 and an auxiliary clamping mechanism 6.

[0038] Reference Figure 2 and Figure 4The tray dismantling mechanism 3 includes a supporting plate 31, a lifting drive 32 and a tray dismantling clamping assembly. The supporting plate 31 is used to lift the pallet 1. The lifting drive 32 is installed at the bottom of the supporting plate 31 to drive the supporting plate 31 to move up and down vertically. Specifically, the lifting drive 32 includes a lifting cylinder vertically fixed to the bottom of the frame 2. The lifting cylinder piston rod is connected to the supporting plate 31 to drive the supporting plate 31 to move up and down vertically through the lifting cylinder. The tray dismantling clamping assembly includes two tray dismantling clamping parts 33, which are respectively located at both ends of the supporting plate 31, and the two tray dismantling clamping parts 33 are relatively movable to cooperate in clamping the pallet 1.

[0039] Reference Figure 4 and Figure 5 The tray removal clamping unit 33 includes a vertical cylinder 331, which is mounted vertically and upwardly on the end of the support plate 31 via a bracket. The top of the piston rod of the vertical cylinder 331 is connected to a horizontal cylinder 332. The horizontal cylinder 332 is arranged horizontally, and the horizontal cylinders 332 of the two tray removal clamping units 33 are arranged opposite each other. The piston rods of the horizontal cylinders 332 are connected to the tray removal clamping plate 333. The top of the tray removal clamping plate 333 is bent to form a bent portion 334, which is arranged away from the corresponding horizontal cylinder 332.

[0040] Reference Figure 3 and Figure 6 The limiting mechanism 4 includes two limiting components arranged on the frame 2, and the two limiting components are located above the two tray clamping parts 33 of the supporting plate 31. The two limiting components cooperate to limit the tray 1.

[0041] Reference Figure 1 and Figure 6 The limiting assembly includes a limiting bracket 40, which is fixed to the frame 2. The limiting bracket 40 is provided with a first limiting portion 41 and a second limiting portion 42, and the first limiting portion 41 is located above the second limiting portion 42. The first limiting portions 41 of the two limiting assemblies cooperate to limit the position of the wooden pallet 1; the second limiting portions 42 of the two limiting assemblies cooperate to limit the position of the plastic pallet 1.

[0042] The first limiting portion 41 includes a first sliding drive member and two limiting rods 411. The two limiting rods 411 are horizontally installed on the limiting bracket 40 via linear bearings. The limiting rods 411 of the two limiting assemblies are located in the same horizontal plane. The limiting rods 411 are made of stainless steel round rods. The first sliding drive member 412 is used to drive the plurality of limiting rods 411 to move horizontally. Specifically, the first sliding drive member 412 includes a first sliding cylinder installed on the limiting bracket 40. The first sliding cylinder is located on the side of the limiting bracket 40 facing away from the frame 2. The piston rod of the first sliding cylinder is connected to a first connecting plate. The two limiting rods 411 are both connected to the first connecting plate. The first sliding cylinder drives its own piston rod to extend and retract, thereby driving the two limiting rods 411 to slide horizontally.

[0043] The second limiting portion 42 includes a limiting splint 421 and a second sliding drive member 422. The limiting splints 421 of the two limiting brackets 40 are located on opposite sides of the two limiting brackets 40. The limiting splints 421 are made of hard plastic or aluminum alloy plates. The second sliding drive member 422 is used to drive the corresponding limiting splints 421 to move horizontally at any time. Specifically, the second sliding drive member 422 includes a second sliding cylinder arranged on the limiting bracket 40. The second sliding cylinder is located on the side of the limiting bracket 40 away from the frame 2. The second sliding cylinder piston rod is connected to the second connecting plate. The second connecting plate is vertically connected to two connecting rods 621 corresponding to the limiting frame plate. The two connecting rods 621 are both horizontally penetrated into the limiting frame 2 through linear bearings, and the two connecting rods 621 are both connected to the corresponding limiting splints 421; the limiting splint 421 can be driven to slide horizontally by the second sliding cylinder driving its own piston rod to extend and retract.

[0044] Reference Figure 2 and Figure 7 The conveying mechanism 5 includes two parallel conveyor belts 51. The input ends of both conveyor belts 51 extend into the frame 2 and are arranged on either side of the support plate 31. The conveyor belts 51 are chain conveyor belts. When the pallet stack is positioned on and facing the support plate 31, the two sides of the pallet 1 extend out of the support plate 31, and the extended portion of the pallet 1 faces the conveyor belts 51.

[0045] Reference Figure 2 、 Figure 4 、 Figure 6 and Figure 7When the wooden pallet 1 is split, the pallet stack is moved into the inner cavity of the frame 2 through the feeding side 20 of the frame 2 and placed on the supporting plates 31 respectively. The lifting drive member 32 drives the supporting plates 31 to move up until the gap between the penultimate pallet 1 and the penultimate pallet 1 at the bottom of the pallet stack is aligned with the limit rods 411 on the two limit assemblies of the limit mechanism 4, and then the first sliding drive member 412 drives the corresponding limit rod 411 to extend into the gap between the penultimate pallet 1 and the penultimate pallet 1; then the lifting drive member 32 drives the supporting plate 31 downward to drive the penultimate pallet 1 downward. When the penultimate supporting plate 31 protrudes from both sides of the supporting plate 31 and overlaps the two conveyor belts 51 respectively, the two conveyor belts 51 cooperate to transfer the pallet 1 out.

[0046] Reference Figures 2 to 7 When splitting the plastic pallet 1, the pallet stack is moved into the inner cavity of the frame 2 through the feeding side 20 of the frame 2 and placed on the supporting plates 31 respectively. The lifting cylinder drives the supporting plates 31 to move up until the second-to-last pallet 1 at the bottom of the pallet stack is aligned with the limiting clamps 421 on the two limiting components of the limiting mechanism 4. The second sliding driving parts 422 of the two limiting components drive the corresponding limiting clamps 421 to abut against the second-to-last pallet 1 at the bottom of the pallet stack, so as to clamp and limit the second-to-last pallet 1 at the bottom of the pallet stack. The vertical cylinder 331 then drives the transverse cylinder 332 upward until the depalletizing plate 333 is aligned with the penultimate pallet 1 at the bottom of the pallet stack, and the bent portion 334 on the depalletizing plate 333 is aligned with the gap between the penultimate and penultimate pallets 1. The transverse cylinder 332 drives the depalletizing plate 333 to abut the penultimate pallet 1, and the bent portion 334 is embedded in the gap between adjacent pallets 1. The lifting cylinder then drives the support plate 31 downward, thereby moving the penultimate pallet 1 downward. When the penultimate support plate 31 protrudes from both sides of the support plate 31 and overlaps the two conveyor belts 51, the transverse cylinder 332 drives the depalletizing plate 333 to retract, and the vertical cylinder 331 drives the transverse cylinder 332 downward until the transverse cylinder 332 and pallet 1 are at the bottom of pallet 1. Finally, the two conveyor belts 51 cooperate to transfer the pallet 1.

[0047] Reference Figure 2 and Figure 8 The frame 2 is also provided with an auxiliary clamping mechanism 6, which includes two auxiliary clamping parts. The two auxiliary clamping parts are respectively located above the two limit assemblies. The two auxiliary clamping parts are relatively movable to clamp the tray 1.

[0048] The auxiliary clamping part includes an auxiliary splint 61 and a swinging drive member 63; the auxiliary splint 61 is rotatably connected to the frame 2 through the rotating shaft 62, and the swinging drive member 63 is used to drive the rotating shaft 62 to drive the auxiliary splint 61 to swing; specifically, the swinging drive member 63 includes a swinging cylinder, the rotating shaft 62 is connected to a connecting rod 621, and the two ends of the swinging cylinder are respectively hinged to the frame 2 and the end of the connecting rod 621 away from the rotating shaft 62, and the hinge axis at both ends of the swinging cylinder is arranged parallel to the axis of the rotating shaft 62.

[0049] When splitting the plastic pallet 1, before the pallet is split, the two limiting parts of the limiting mechanism 4 cooperate with the pallet splitting clamping parts 33 at both ends of the support plate 31 to perform the pallet splitting process, the swing driving parts 63 of the two auxiliary clamping parts first drive the corresponding auxiliary clamping plates 61 to swing toward the pallet stack on the support plate 31, so as to utilize the two auxiliary clamping plates 61 to clamp and limit the pallet 1 in the lower part of the pallet stack, thereby limiting the gravity load of the pallet 1 on the upper part of the pallet stack acting on the lower pallet 1, causing the gap between the pallets 1 to be reduced, affecting the subsequent situation where the bending part 334 of the pallet splitting clamping part 33 is stuck in the gap between adjacent pallets 1, and at the same time, it can limit the situation where the support legs 11 between adjacent pallets 1 are too tightly clamped due to the gravity of the upper pallet 1.

[0050] Reference Figure 2 and Figure 9 Two vertical stoppers 21 are installed on the inner side of the frame 2, except for the loading side 20. The stoppers 21 are located above the pallet removal station. The stoppers 21 in the inner cavity of the frame 2 are used to initially limit the position of the pallet stack moved into the inner cavity of the frame 2, so that the pallet stack can be moved more accurately above the support plate 31.

[0051] The limit baffle 21 is vertically connected to a plurality of connecting screws on the side facing the frame 2. The connecting screws are passed through the frame 2. The connecting screws are threadedly connected to two connecting nuts. The two connecting nuts are respectively abutted against the inner and outer sides of the frame 2 to achieve adjustable gap between the limit baffle 21 and the frame 2, which is convenient for subsequent adjustment of the position of the limit baffle 21 according to the size of the pallet 1.

[0052] Guide plates 201 are connected to opposite sides of the loading side 20 of the frame 2. The two guide plates 201 extend outward away from the loading side 20 to form a flared structure, which facilitates moving the pallet stack into the interior of the frame 2 through the loading side 20.

[0053] Reference Figure 2 and Figure 9The frame 2 is also provided with a positioning mechanism, which is located below the limiting mechanism 4; the positioning mechanism is located at the bottom of the limiting baffle 21; the positioning mechanism includes a positioning baffle 221 and a positioning portion, and the positioning baffle 221 is provided at two locations, and the two positioning baffles 221 are provided at the bottom of the feeding side 20 of the frame 2; the positioning portion is located on the side of the frame 2 opposite to the feeding side 20, and the positioning portion includes a positioning push plate 222 and a positioning drive 223, the positioning push plate 222 is arranged opposite to the positioning baffle 221, and the positioning drive 223 is used to drive the positioning push plate 222 to move toward or away from the positioning baffle 221; specifically, the positioning drive 223 includes a positioning cylinder, which is fixed to the frame 2 through a bracket, and the positioning cylinder piston rod is connected to the positioning push plate 222. When the positioning drive 223 drives the positioning push plate 222 to push the tray 1 located on the supporting plate 31 to abut against the positioning baffle 221, the opposite sides of the tray 1 respectively extend out of the opposite sides of the supporting plate 31.

[0054] When the wooden pallet 1 is to be disassembled, before the pallet stack is disassembled, the two limiting parts of the limiting mechanism 4 cooperate with the pallet disassembly clamping parts 33 at both ends of the supporting plate 31. The positioning driving member 223 first drives the positioning push plate 222 to push the penultimate pallet 1 on the supporting plate 31 and position it on the two limiting baffles 221 at the bottom of the loading side 20 to position the pallet 1, ensuring that the opposite sides of the pallet 1 extend evenly from the opposite sides of the supporting plate 31, and limiting the situation where the pallet 1 on the supporting plate 31 cannot be connected with the two conveyor belts 51 of the conveying mechanism 5 when the supporting plate 31 moves down due to the misalignment between the upper and lower parts of the wooden pallet 1.

[0055] The implementation principle of this embodiment is: When disassembling the wooden pallet 1, the following steps are included: S1: Pallet stack in place: The pallet stack is moved into the interior of the frame 2 through the loading side 20 of the frame 2 and placed on the support plate 31; S2: Position adjustment of pallet 1: The lifting drive member 32 drives the supporting plate 31 to move the pallet stack until the penultimate pallet 1 at the bottom of the pallet stack is opposite to the positioning assembly 22, and the gap between the penultimate pallet 1 and the penultimate pallet 1 is opposite to the limiting rod 411 of the limiting mechanism 4; S3: Positioning of pallet 1: The positioning drive 223 drives the positioning push plate 222 to push the last pallet 1 in the pallet stack and abut against the two positioning stoppers 221 at the bottom of the opening side of the frame 2; then the positioning drive 223 drives the positioning push plate 222 to retract and return to its original position; S4: The limiting mechanism 4 limits: The first limiting portion 41 of the limiting mechanism 4 drives the limiting rod 411 to extend into the gap between the penultimate tray 1 and the penultimate tray 1 through the first sliding driving member 412; S5: Separation of the pallet 1: The lifting drive 32 drives the supporting plate 31 to move the penultimate pallet 1 downward until the two opposite sides of the penultimate pallet 1 respectively abut against the two conveyor belts 51 of the conveying mechanism 5; S6: Transfer of pallet 1: The two conveyor belts 51 cooperate to transfer the pallet 1 out; S7: The lifting drive member 32 drives the supporting plate 31 to move upward and abut against the bottom of the last pallet from the bottom of the pallet stack; S8: The limiting mechanism 4 releases the limit: The limiting mechanism 4 drives the limiting rod 411 to retract and return to its original position through the first sliding driving member 412: S9: Repeat steps S2 to S8 until the remaining pallet 1 in the pallet stack is depalletized.

[0056] When disassembling the plastic pallet 1, the following steps are included: S1: Pallet stack in place: The pallet stack is moved into the interior of the frame 2 through the loading side 20 of the frame 2 and placed on the support plate 31; S2: Position adjustment of pallet 1: the lifting drive 32 drives the supporting plate 31 to move the pallet stack until the second-to-last pallet 1 at the bottom of the pallet stack faces the limiting clamping plate 421 of the limiting mechanism 4; and the fourth-to-last pallet 1 faces the auxiliary clamping plate 61 of the auxiliary clamping mechanism 6; S3: Temporary fixation of the upper pallet 1: The swing driving members 63 of the two auxiliary clamping parts drive the corresponding auxiliary clamping plates 61 to swing toward the pallet 1 of the pallet stack. The two auxiliary clamping plates 61 are used to clamp and limit the pallet 1 in the upper area of ​​the pallet stack to prevent the load of the upper pallet 1 from directly acting on the lower pallet 1. S4: The limiting mechanism 4 limits: The second limiting portion 42 of the limiting mechanism 4 drives the limiting clamping plate 421 to abut against the second-to-last pallet 1 of the pallet stack via the second sliding driving member 422, so that the two limiting clamping plates 421 cooperate to clamp and limit the pallet 1; S5: The tray removal clamping part 33 is put into position: the vertical cylinder 331 drives the horizontal cylinder 332 to move the tray removal clamping plate 333 upward until the tray removal clamping plate 333 is opposite to the penultimate tray 1, and the bent portion 334 is opposite to the gap between the penultimate tray 1 and the penultimate tray 1; then the horizontal cylinder 332 drives the tray removal clamping plate 333 to abut against the tray 1, and the bent portion 334 extends into the gap between the first tray 1 and the penultimate tray 1; S6: Separation of the pallet 1: The lifting drive member 32 drives the supporting plate 31 to move the penultimate pallet 1 downward until the two opposite sides of the penultimate pallet 1 respectively abut against the two conveyor belts 51 of the conveying mechanism 5; S7: The tray removal clamping portion 33 is reset: the horizontal cylinder 332 drives the tray removal clamping plate 333 to separate from the tray 1; the vertical cylinder 331 drives the horizontal cylinder 332 to drive the tray removal clamping plate 333 to move downward until the tray removal clamping plate 333 is located below the tray 1; S8: Transfer of pallet 1: The pallet 1 is transferred out by the cooperation of two conveyor belts 51; S9: The lifting drive member 32 drives the supporting plate 31 to move upward and abut against the bottom of the last pallet from the bottom of the pallet stack; S10: The limiting mechanism 4 releases the limit: the limiting mechanism 4 drives the limiting clamp 421 to retract and return to its original position through the second sliding driving member 422; S11: Repeat steps S2 to S10 until the remaining pallet 1 in the pallet stack is depalletized.

[0057] The automatic pallet disassembly machine of the present application can simultaneously meet the requirements of the disassembly processing of conventional wooden pallets 1 and plastic pallets 1, effectively improving the disassembly adaptability and efficiency of the pallet 1.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
