Abstract
Description
Technical Field
[0001] This invention relates to the field of pallet conveying technology, and in particular to a pallet stack splitting device and a pallet stack splitting method. Background Technology
[0002] Currently, in automated production lines for custom panel furniture, pads are placed at the bottom of each stack of panels to reduce damage during transport. After use, these pads are stacked by robots or other equipment. To enable the secondary use of these pads, a pad stack splitting mechanism is typically required for transporting and splitting the stacks.
[0003] For example, Chinese patent application CN115402777A discloses a pallet separating machine, a pallet separating method, and a detection and palletizing separating production line. This method separates pallets one by one using a clamping device, places them on a conveyor belt, and transports them to the next process. While it can separate stacked pallets, this clamping method is only suitable for small, long, narrow pallets and cannot accommodate larger pallets, exhibiting poor adaptability.
[0004] In addition, Chinese patent application CN116788794A discloses a pad loading device that uses a linear drive mechanism and two clamping mechanisms to clamp and transport pads. Although it can disassemble large pads, it requires not only horizontal mechanisms but also vertical mechanisms to achieve disassembly. It requires many parts, occupies a large space, and is difficult to adapt to small-scale enterprises. Moreover, it requires multiple mechanisms to work together to complete the loading of a single pad, resulting in low work efficiency.
[0005] Therefore, how to improve the disassembly efficiency and reduce the footprint of the entire equipment while disassembling large-volume pads is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] The primary objective of this invention is to provide a pad stack splitting device that can split large-volume pads by utilizing the weight of the pads themselves and the use of limiting plates to complete the splitting of the pad stack. The structure is simpler, reduces the footprint of the entire device, and has higher splitting efficiency.
[0007] The second objective of this invention is to provide a method for splitting pallet stacks, which can split large-volume pallets and avoids cumbersome splitting processes, resulting in higher splitting efficiency.
[0008] To achieve the aforementioned primary objective, the present invention provides the following technical solution:
[0009] A pallet stack splitting device is provided, comprising:
[0010] frame;
[0011] A conveying device, comprising a conveying roller, a conveying motor, and a conveying transmission mechanism, wherein the conveying roller is rotatably connected to the frame, the conveying motor is connected to the conveying roller through the conveying transmission mechanism, and the conveying roller conveys a stack of pads along a first direction;
[0012] A splitting device, comprising a push plate and a splitting transmission mechanism, wherein the splitting transmission mechanism is disposed on the frame, the conveying motor is connected to the splitting transmission mechanism, and the splitting transmission mechanism is connected to the push plate to drive the push plate to move above the conveying roller and to move along the first direction;
[0013] A limiting device, comprising a limiting plate disposed on the frame, wherein a limiting gap is provided between the limiting plate and the conveying roller.
[0014] With the above scheme, during operation, the previous station transports the stacked pallet stack to the conveying device. At this time, the push plate is located below the conveying roller. The conveying device transports the pallet stack along the first direction. At the same time, the conveying motor drives the push plate to move above the conveying roller and to the side of the pallet stack away from the limiting plate. The conveying device transports the pallet stack to the limiting plate along the first direction. The limiting plate blocks the movement of the pallet stack. The conveying motor continues to drive the push plate to move along the first direction. The push plate pushes the bottom pallet in the pallet stack to continue moving. The bottom pallet in the pallet stack leaves the conveying device through the limiting gap and moves to the next station. The conveying motor continues to drive the push plate to move below the conveying roller and to the side of the pallet stack away from the limiting plate. The conveying motor continues to drive the push plate to move along the first direction. The push plate pushes the bottom pallet in the pallet stack to leave the conveying device through the limiting gap and move to the next station. This process is repeated to complete the splitting of the pallet stack.
[0015] Understandably, this method allows for the disassembly of both large and small pallets, including those without gaps between them, offering greater adaptability. Furthermore, by simply adding a disassembly and limiting device to the basic conveyor system, the weight of the pallets themselves and the limiting plates work together to disassemble the pallet stack. This simplifies the overall structure, reduces the space required for the equipment, avoids cumbersome disassembly processes, and increases disassembly efficiency.

The inner beam is located outside the intermediate beam, and the outer beam is located outside the inner beam. One end of the conveying roller is rotatably connected to the inner beam, and the other end of the conveying roller is rotatably connected to the outer beam.
[0021] Optionally, the pallet stacking and splitting device further includes an infeed detection unit, an outfeed detection unit, a limit detection unit, and a pusher detection unit. The infeed detection unit is located on the frame and at one end away from the limit device. The outfeed detection unit is located on the frame and below the limit gap. The limit detection unit is located on the frame and on the side of the outfeed detection unit closer to the conveyor roller. The pusher detection unit is located on the frame and at one end away from the limit device.

The limiting adjustment seat is provided with an adjusting waist-shaped hole. The limiting adjustment bolt passes through the adjusting waist-shaped hole and is threadedly connected to the limiting plate.
[0024] To achieve the second objective mentioned above, the present invention provides the following technical solution:
[0025] A method for dismantling pallet stacks is provided, using the aforementioned pallet stack dismantling equipment, comprising the following steps:
[0026] S1. The previous station transports the stacked pallets to the conveying device, at which time the push plate is located under the conveying roller.

Furthermore, only a splitting device and a limiting device need to be installed on the basic conveying device to utilize the weight of the pallets themselves and the limiting plate to complete the splitting of the pallet stack. The overall structure is simpler, reducing the space occupied by the entire device, and avoiding cumbersome splitting processes, resulting in higher splitting efficiency.

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0045] like Figures 1 to 7 As shown, the present invention provides a pallet stack splitting device, including a frame 1, a conveying device 2, a splitting device 3 and a limiting device 4.
[0046] For ease of explanation, in this embodiment, each orientation is as follows: Figure 1 As shown, the first direction is the front-to-back direction.
[0047] The frame 1 provides support for the entire equipment, ensuring its stability and robustness. The conveying device 2 includes a conveying roller 21, a conveying motor 22, and a conveying transmission mechanism. The conveying roller 21 is rotatably connected to the frame 1. Specifically, as shown... Figure 1 As shown, multiple conveying rollers 21 are spaced apart on the frame 1 in the front-to-back direction. The conveying motor 22 is connected to the conveying rollers 21 through the conveying transmission mechanism. The conveying rollers 21 convey the pallet stack from front to back in the first direction.
[0048] Furthermore, the splitting device 3 includes a push plate 31 and a splitting transmission mechanism. The splitting transmission mechanism is located on the frame 1. The conveying motor 22 is connected to the splitting transmission mechanism, and the splitting transmission mechanism is connected to the push plate 31 to drive the push plate 31 to move above the conveying roller 21 and move along the first direction. Specifically, before the pallet stack enters the conveying area, the push plate 31 is located below the conveying roller 21 and will not affect the entry of the pallet stack. When the pallet stack enters the conveying area, that is, when it is on the conveying roller 21, during the conveying process, the conveying motor 22 drives the conveying roller 21 to move synchronously through the splitting transmission mechanism.
[0049] Furthermore, the limiting device 4 includes a limiting plate 41, which is located on the frame 1. A limiting gap is provided between the limiting plate 41 and the conveying roller 21. Specifically, the limiting plate 41 is located on the rear side of the frame 1, and a limiting gap is provided between the limiting plate 41 and the conveying roller 21, which is just enough for a pad to pass through.
[0050] With the above scheme, during operation, the previous workstation transports the stacked pallet stack to the conveying device 2. At this time, the push plate 31 is located below the conveying roller 21. The conveying device 2 transports the pallet stack from front to back along the first direction. After the pallet stack enters the conveying area, the conveying motor 22 simultaneously drives the push plate 31 to move above the conveying roller 21 and to the front of the pallet stack. The conveying device 2 transports the pallet stack along the first direction to the limiting plate 41. The limiting plate 41 blocks the movement of the pallet stack. The conveying motor 22 continues to drive the push plate 31 to move backward. Block 31 pushes the bottommost pad in the pad stack to continue moving. The bottommost pad in the pad stack leaves the conveyor device 2 through the limiting gap and moves to the next station. The conveyor motor 22 continues to drive the pusher plate 31 to move below the conveyor roller 21 and to the front of the pad stack away from the limiting plate 41. The conveyor motor 22 continues to drive the pusher plate 31 to move backward. The pusher plate 31 continues to push the bottommost pad in the pad stack to leave the conveyor device 2 through the limiting gap and move to the next station. This process is repeated to complete the splitting of the pad stack.
[0051] Understandably, this method allows for the disassembly of both large and small pallets, including those without gaps between them, offering greater adaptability. Furthermore, by simply adding a disassembly device 3 and a limiting device 4 to the basic conveyor device 2, the weight of the pallets themselves and the limiting plate 41 can be used to disassemble the pallet stack. The overall structure is simpler, eliminating the need for lifting and clamping devices commonly found in existing disassembly equipment, thus reducing the space required and avoiding cumbersome disassembly processes, resulting in higher disassembly efficiency. Moreover, the simple structure allows for the disassembly of pallet stacks, making it suitable for small-scale production enterprises and reducing their production costs.
[0052] In some embodiments, the pallet stack splitting device also includes an industrial computer, which is electrically connected to the conveying device 2, the splitting device 3 and the limiting device 4 respectively, resulting in a higher degree of automation.
[0053] In some embodiments, such as Figure 6 As shown, the frame 1 includes a middle beam 11, with both ends of the middle beam 11 extending along a first direction. Conveying rollers 21 are provided on both the left and right sides of the middle beam 11. The splitting transmission mechanism includes a splitting transmission chain 32 and two splitting transmission sprockets 33. The two splitting transmission sprockets 33 are spaced apart on the middle beam 11 along the first direction. The splitting transmission chain 32 is wound around the two splitting transmission sprockets 33. The push plate 31 is detachably connected to the splitting transmission chain 32. The conveying motor 22 is connected to one of the splitting transmission sprockets 33.
[0054] Specifically, the frame 1 is a frame structure. The middle beam 11 is located in the middle of the frame of the entire frame 1. The two ends of the middle beam 11 extend in the front and rear directions. Two split transmission sprockets 33 are respectively located at the front and rear ends of the middle beam 11. The split transmission chain 32 is wound around the two split transmission sprockets 33 to form a circular movement path for the push plate 31, so that the push plate 31 can rise above the conveyor roller 21 and also fall below the conveyor roller 21.
[0055] More specifically, the previous station transports the stacked pallets to the conveyor 2. Before the pallets enter the conveying area, the push plate 31 is located below the conveyor roller 21 and behind the conveyor 2, so it does not affect the entry of the pallets. The conveyor 2 transports the pallets forward. While the conveyor motor 22 drives the conveyor roller 21 to move, it also drives the splitting transmission chain 32 to move, thereby causing the push plate 31 to move forward from below the rear side along the trajectory of the splitting transmission chain 32, and then move to the top of the conveyor roller 21. Since both the conveying device 2 and the splitting transmission chain 32 are moving simultaneously, when the push plate 31 moves above the conveying roller 21, the push plate 31 is always located in front of the pad stack. The conveying device 2 conveys the pad stack backward to the limiting plate 41, which blocks the movement of the pad stack. Meanwhile, the conveying motor 22 continues to drive the push plate 31 to move backward. The push plate 31 pushes the bottom pad in the pad stack to continue moving. The bottom pad in the pad stack leaves the conveying device 2 from the limiting gap and moves to the next station.
[0056] Next, the conveyor motor 22 continues to drive the splitting transmission chain 32 to move, thereby driving the push plate 31 to move backward and downward along the trajectory of the splitting transmission chain 32, and then move forward from the lower rear side. Next, it moves to the front side of the pad stack along the trajectory of the splitting transmission chain 32. The push plate 31 pushes the bottom pad in the pad stack to continue moving. The bottom pad in the pad stack leaves the conveyor device 2 from the limiting gap and moves to the next station. In this way, it is repeated continuously, so that the bottom pad in the pad stack is pushed out of the limiting gap from the conveyor device 2 and moved to the next station one by one.
[0057] Understandably, compared to existing splitting equipment that requires a lifting device to drive a clamping device to hold the pads and split them from above, the pad stack splitting equipment of the present invention only needs to set a splitting device 3 and a limiting device 4 on the basic conveying device 2. It can use the weight of the pads themselves and the limiting plate 41 to complete the splitting of the pad stack. The overall structure is simpler. The power of the splitting device 3 is provided by the conveying device 2, while the limiting device 4 is a non-powered device. Compared with the existing method, it can reduce the setting of power sources, reduce the control process, reduce the probability of errors, avoid the cumbersome splitting process, and achieve higher splitting efficiency.
[0058] In addition, the splitting device 3 is embedded between the frame 1 and the conveyor roller 21, which greatly reduces the footprint of the entire equipment and makes higher space utilization. The simple structure can complete the splitting of the pallet stack, making it suitable for small-scale production enterprises and reducing their production costs.
[0059] In some embodiments, such as Figure 6 As shown, the splitting device 3 also includes a splitting guide rail 34, which is located on the intermediate beam 11. The splitting guide rail 34 can be installed on the intermediate beam 11 by bolts. The splitting guide rail 34 is provided with a splitting guide groove that is compatible with the splitting transmission chain 32.
[0060] Specifically, the two ends of the split guide rail 34 extend in the front-to-back direction. The material of the split guide rail 34 can be aluminum profile or hard rubber, etc. The shape of the split guide groove is adapted to the shape of the split transmission chain 32, which can prevent the split transmission chain 32 from shifting left and right during the movement, making the movement of the push plate 31 more stable and able to push the pad more powerfully.
[0061] In some embodiments, a split guide rail 34 is provided above the middle beam 11. In some other embodiments, split guide rails 34 are provided above and below the two middle beams, resulting in better guiding effect.
[0062] In some embodiments, such as Figure 7 As shown, the push plate 31 is detachably mounted on the split transmission chain 32 via a common chain connector, making disassembly and assembly more convenient.
[0063] In some embodiments, the push plate 31 is a rectangular parallelepiped structure, which can better push the pad.
[0064] In some embodiments, such as Figure 7 As shown, the upper surface of the push plate 31 is designed to be inclined. Specifically, the upper surface of the push plate 31 is inclined downward and forward. When the push plate 31 pushes the bottom pad of the pad stack away, the upper pad stack will move downward due to gravity. By setting the inclined surface, the upper pad stack can be tilted and slowly descended, which can reduce the friction between the push plate 31 and the pad stack, and also prevent the pad stack from falling directly, thus improving the safety of the equipment.
[0065] In some embodiments, such as Figure 4 and Figure 6As shown, the conveying transmission mechanism includes a conveying transmission chain 23, a conveying transmission sprocket 24, and a conveying transmission shaft 25. The conveying transmission shaft 25 is located at the front end of the intermediate beam 11. One of the split transmission sprockets 33 is connected to the middle of the conveying transmission shaft 25. Conveying transmission sprockets 24 are provided at both the left and right ends of the conveying transmission shaft 25. The conveying motor 22 is located on the frame 1. The conveying motor 22 is connected to the conveying transmission shaft 25 through the conveying transmission chain 23 and the conveying transmission sprocket 24. In the first direction, two adjacent conveying rollers 21 are connected through the conveying transmission chain 23 and the conveying transmission sprocket 24.
[0066] Specifically, the conveyor motor 22 transmits power to the conveyor drive shaft 25 through the conveyor drive chain 23 and the conveyor drive sprocket 24. The conveyor drive shaft 25 then transmits power to the split drive sprocket 33 and the split drive chain 32, thereby transmitting power to the push plate 31. It can be understood that while the conveyor motor 22 is driving the conveyor roller 21 to move, it is also driving the split drive chain 32 to move. In other words, one power source solves the motion problem of two mechanisms. Compared with the existing method, it can reduce the number of power sources, reduce the control process, reduce the probability of errors, avoid the cumbersome splitting process, and achieve higher splitting efficiency.
[0067] In some embodiments, the conveying roller 21 includes a drive roller assembly and a non-powered roller assembly. The drive roller assembly is located on the side of the frame 1 away from the limiting device 4, and the non-powered roller assembly is located on the side of the frame 1 close to the limiting device 4. The drive roller assembly is connected to the conveying motor 22 through the conveying drive chain 23 and the conveying drive sprocket 24.
[0068] Specifically, such as Figure 1 and Figure 2 As shown, the four sets of conveyor rollers 21 near the front are drive roller sets, powered by the conveyor motor 22, which provides initial power for the conveying of the pallet stack. The other conveyor rollers 21 near the rear are unpowered roller sets. The conveyor rollers 21 in the unpowered roller sets are interconnected by chains, sprockets, or belts. The conveyor rollers 21 in the unpowered roller sets may not be connected to each other. The unpowered roller sets are not connected to the drive roller sets. After the pallet stack enters the unpowered roller sets, the inertia of the pallet stack will drive it to move backward. By setting up unpowered roller sets, the load on the conveyor motor 22 can be reduced, thereby ensuring that the push plate 31 has a certain amount of pushing force to push away the bottom pallet of the pallet stack, and also reducing production costs.
[0069] In some embodiments, the frame 1 can be tilted slightly downwards and to the rear, allowing the pallet stack to move backwards more effectively due to the rolling friction from the conveying roller 21.
[0070] In some embodiments, such as Figure 6 As shown, the frame 1 includes an outer beam 12, an inner beam 13, and multiple support bases 14. The multiple support bases 14 are spaced apart along a first direction. The middle beam 11, the outer beam 12, and the inner beam 13 are all located on the support bases 14. The inner beam 13 is located outside the middle beam 11, and the outer beam 12 is located outside the inner beam 13. One end of the conveying roller 21 is rotatably connected to the inner beam 13, and the other end of the conveying roller 21 is rotatably connected to the outer beam 12.
[0071] Specifically, such as Figure 1 As shown, the frame 1 also includes a first sealing plate 15 and a second sealing plate 16. The first sealing plate, the second sealing plate 16 and the two outer beams 12 form the overall frame of the frame 1. The first sealing plate 15 is located on the front side and the second sealing plate 16 is located on the rear side. The two outer beams 12 are supported on the support base 14. The middle beam 11 is supported on the support base 14 and located in the middle of the overall frame. There is space between the middle beam 11 and the support base 14 for the splitting transmission chain 32 and the push plate 31 to pass through. There are inner beams 13 on both the left and right sides of the middle beam 11. The inner beams 13 are supported on the support base 14. The middle beam 11 mainly serves to support the splitting device 3, while the inner beams 13 and the outer beams 12 mainly serve to support the conveying device 2, thereby improving the stability of the overall structure.
[0072] In some embodiments, such as Figure 6 As shown, the frame 1 also includes a tray 17, which is located on the support base 14 and below the intermediate beam 11. The tray 17 has a U-shaped cross-section. A channel is formed between the top of the tray 17 and the intermediate beam 11 for the split transmission chain 32 and the push plate 31 to pass through. At the same time, it can also prevent the split transmission chain 32 from falling off, thus improving safety.
[0073] In some embodiments, such as Figure 1 As shown, the frame 1 also includes a dust cover 18, which is located on the support base 14 and at the transmission roller assembly. The dust cover 18 is used to protect the conveyor motor 22 and the conveyor transmission mechanism, improve safety, and extend the service life of the equipment.
[0074] In some embodiments, such as Figure 6 As shown, the frame 1 also includes multiple adjustable feet 19. Each support base 14 has an adjustable foot 19 below it, which can adjust the height of the support base 14, thereby adjusting the height of the entire frame 1. The heights of different support bases 14 can also be different, thereby adjusting the tilt of the entire frame 1, that is, adjusting the conveying direction of the conveying roller 21. It can convey slightly backward and downward, which has better adaptability and can realize the docking of different workstations.
[0075] In some embodiments, such as Figure 1 and Figure 6As shown, the pallet stacking and splitting equipment also includes a pallet infeed detection unit 5, a pallet outfeed detection unit 6, a limit detection unit 7, and a pusher detection unit 8. The pallet infeed detection unit 5, the pallet outfeed detection unit 6, the limit detection unit 7, and the pusher detection unit 8 are all electrically connected to the industrial control machine. The pallet infeed detection unit 5 is located on the frame 1 and at one end away from the limit device 4. The pallet outfeed detection unit 6 is located on the frame 1 and below the limit gap. The limit detection unit 7 is located on the frame 1 and on the side of the pallet outfeed detection unit 6 close to the conveyor roller 21. The pusher detection unit 8 is located on the frame 1 and at one end away from the limit device 4.
[0076] Specifically, the infeed detection unit 5 is located on the front side of the outer beam 12 and is used to detect whether the pallet stack has reached the entrance position of the equipment. When the infeed detection unit 5 detects that the pallet stack has entered the conveying area of the conveying device 2, the infeed detection unit 5 will transmit an electrical signal to the industrial control computer, and the industrial control computer will control the conveying device 2 to convey the pallet stack.
[0077] More specifically, the plate discharge detection unit 6 is located on the frame 1 and below the limiting gap. The plate discharge detection unit 6 is located on the rear side of the outer beam 12 and is used to detect whether the pad has been pushed away from the conveying device 2 by the push plate 31, which has a higher degree of automation.
[0078] Furthermore, both the first sealing plate 15 and the second sealing plate are equipped with a push plate detection unit 8. The push plate detection unit 8 is used to detect the position of the push plate 31. When the push plate 31 moves upward from below the conveying roller 21, it will trigger the push plate detection unit 8 located on the first sealing plate 15. When the push plate 31 moves downward from above the conveying roller 21, it will trigger the push plate detection unit 8 located on the second sealing plate 16, thus achieving a higher degree of automation.
[0079] During operation, the limit detection unit 7 is located on the frame 1 and in front of the plate output detection unit 6. The limit detection unit 7 is located on the outer beam 12 and is used to detect whether the pad stack has reached the limit plate 41. If the plate entry detection unit 5 detects that a pad stack has entered, the plate output detection unit 6 will also detect that pads are being pushed out one after another. When the limit detection unit 7 does not detect a pad stack, it means that all pads have been disassembled. At this time, the conveying device 2 continues to work to drive the push plate 31 to move backward until the push plate 31 triggers the push plate detection unit 8 located on the second sealing plate 16, indicating that the push plate 31 is located below the conveying roller 21 and will not affect the entry of subsequent pad stacks. Then the conveying device 2 stops working and waits for the next pad stack disassembly operation. The whole process is highly automated, which can reduce unnecessary energy waste and reduce the production cost of enterprises.
[0080] In some embodiments, the board entry detection unit 5, the board exit detection unit 6, and the limit detection unit 7 are all limit switches, which are more adaptable to the movement of the pad and can better sense whether the pad has passed by.
[0081] In some embodiments, the push plate detection unit 8 is a proximity switch, which can better sense the push plate 31.
[0082] In some embodiments, such as Figure 1 As shown, the pallet stacking and splitting equipment also includes a limiting guide plate 9, which is located on the frame 1. Limiting guide plates 9 are provided on both sides of the conveying device 2.
[0083] Specifically, the upper surfaces of the two outer beams 12 are provided with limiting guide plates 9. The limiting guide plates 9 can better guide the movement of the pad stack and prevent the pad stack from leaving the conveyor roller 21, thus improving safety.
[0084] In some embodiments, the front and rear ends of the limiting guide plate 9 are provided with guide ramps to facilitate the entry of the pad stack into the equipment and to facilitate the removal of the disassembled pad from the equipment.
[0085] In some embodiments, the limiting guide plate 9 is detachably installed on the outer beam 12 by bolts. In actual use, the limiting guide plate 9 of different widths can be used according to the different sizes of pads, thereby adjusting the distance between the two limiting guide plates 9, which can adapt to pads of different sizes and has better adaptability.
[0086] In some embodiments, such as Figure 1 As shown, the pad stack splitting device also includes a limit adjustment cylinder 10. The limit adjustment cylinder 10 is located on the outer beam 12. The piston rod of the limit adjustment cylinder 10 is connected to the limit guide plate 9 to drive the limit guide plate 9 to move towards the inner beam 13. In this way, the distance between the two limit guide plates 9 can be adjusted, which can adapt to pads of different sizes, making it more adaptable and easier to operate.
[0087] Specifically, the limit adjustment cylinder 10 is an adjustable stroke cylinder, which can achieve stepless adjustment and is more convenient to adjust.
[0088] In some embodiments, such as Figure 2 As shown, the limiting device 4 also includes a limiting adjustment seat 42 and a limiting adjustment bolt. The limiting adjustment seat 42 is detachably connected to the frame 1. The limiting adjustment seat 42 is provided with an adjusting waist-shaped hole 43. The limiting adjustment bolt passes through the adjusting waist-shaped hole 43 and is threadedly connected to the limiting plate 41.
[0089] Specifically, by adjusting the waist-shaped hole 43 to extend vertically, the limiting adjustment bolt can be installed in the position of the adjusting waist-shaped hole 43, thereby changing the position of the limiting plate 41 in the vertical direction, and thus adjusting the size of the limiting gap, so as to adapt to pads of different thicknesses and have better adaptability.
[0090] Embodiments of the present invention also provide a method for splitting pallet stacks. Using the above-mentioned pallet stack splitting equipment, large-volume pallets can be split, and the cumbersome splitting process is avoided, resulting in higher splitting efficiency.
[0091] An embodiment of the present invention provides a method for disassembling a stack of pallets, comprising the following steps:
[0092] S1. The previous station transports the stacked pallets to the conveying device 2. At this time, the push plate 31 is located under the conveying roller 21.
[0093] S2. The conveying device 2 conveys the pad stack along the first direction, and the conveying motor 22 simultaneously drives the push plate 31 to move above the conveying roller 21 and to the side of the pad stack away from the limiting plate 41.
[0094] S3. The conveying device 2 conveys the pad stack along the first direction to the limiting plate 41, and the limiting plate 41 blocks the movement of the pad stack.
[0095] S4. The conveyor motor 22 continues to drive the push plate 31 to move along the first direction. The push plate 31 pushes the bottommost pad in the pad stack to continue moving. The bottommost pad in the pad stack leaves the conveyor device 2 from the limiting gap and moves to the next station.
[0096] S5. The conveyor motor 22 continues to drive the push plate 31 to move below the conveyor roller 21 and to the side of the pad stack away from the limiting plate 41. The conveyor motor 22 continues to drive the push plate 31 to move along the first direction. The push plate 31 continues to push the bottom pad of the pad stack out of the limiting gap from the conveyor device 2 and move to the next station. This process is repeated to complete the splitting of the pad stack.
[0097] The above description is only a partial embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
