Description

Technical Field

[0001] The present invention relates to the technical field of palletizing devices, in particular to a wooden pallet stacking device. Background Art

[0002] As a widely used logistics loading tool, wooden pallets are usually composed of components such as panels, frames, beams and bottom support bars. The use environment of wooden pallets is extremely wide, covering all aspects from warehouse storage, logistics transportation to production workshops. The use of wooden pallets has many benefits. First, wooden pallets have high strength and load-bearing capacity, which can meet the loading needs of goods of different weights. Secondly, wooden pallets are easy to clean and maintain, and have a relatively long service life, which reduces the operating costs of enterprises. In addition, wooden pallets are also environmentally friendly and can be recycled and reused, which is in line with the green logistics concept of modern enterprises.

[0003] In the prior art, a Chinese patent document with publication number CN117533797A proposes a wooden pallet stacking device, comprising a first conveyor belt and a second conveyor belt, wherein the load surface of the second conveyor belt is higher than the first conveyor belt, and further comprising a lifting device, a supporting member and a pushing device, wherein the lifting device is used to move the wooden pallet from a first position to a second position, wherein the first position is located at the tail end of the transmission track of the first conveyor belt, and the second position is located directly above the first position. Although the wooden pallet of the application is transferred from the first position to the second position for stacking, it is transferred to the third position via the pushing device after the stacking is completed. In the process of transferring the wooden pallet from the first conveyor belt to the second conveyor belt, the stacking of the wooden pallet is completed at the same time, thereby improving the transportation and loading efficiency of the wooden pallet, and by cooperating with the lifting device and the supporting member, a plurality of wooden pallets can be stacked on the supporting member in sequence only by the extension and contraction of the third cylinder, thereby improving the efficiency of stacking wooden pallets, but the The technology is consistent with the traditional method in that after the wooden pallet stacking operation is completed, the insufficient space utilization becomes a significant problem. This is mainly because in the design of the existing wooden pallet, the support bars at the bottom are deliberately set with intervals in order to reduce the overall weight. However, in the actual stacking process, this design causes the support bars of the upper wooden pallet to be directly placed on the panel of the lower wooden pallet, rather than being tightly connected with the support bars of the lower wooden pallet. As a result, a large gap is inevitably formed between the upper and lower wooden pallets. These gaps are not only not effectively utilized, but have become the source of space waste. This phenomenon of space waste directly leads to an increase in the height of the overall structure after stacking. The increase in height not only takes up more storage space, but also further increases the difficulty of operating logistics equipment such as forklifts when transferring pallets. This problem is particularly prominent in scenarios where warehouse space is limited and logistics efficiency requirements are high.

[0004] Furthermore, we disclose a wooden pallet stacking device to meet the actual needs of the existing stacking method that wastes a lot of space and increases the difficulty of subsequent transfer. Summary of the Invention

[0030] like Figures 1 to 7As shown, a wooden pallet stacking device comprises a conveyor frame 6 for conveying wooden pallets and a carrier frame 1 for holding them during stacking. The carrier frame 1 is arranged on one side of the conveyor frame 6 and is connected by a connecting piece. The upper end of the conveyor frame 6 is fixedly connected to one end of the carrier frame 1, and the baffle is used to limit the position of the wooden pallet. Both sides of the upper end surface of the carrier frame 1 are fixedly connected to a baffle 2. A clamping drive mechanism 8 is provided on the conveyor frame 6 at the upper end of the wooden pallet. Both sides of the lower end of the clamping drive mechanism 8 are transmission-connected with a splint 7. The lower ends of the two splints 7 are provided with an anti-slip clamping foot 15. A second guide frame 12, a first guide frame 3, and a second guide frame 13 are provided on one side of the conveyor frame 6 and the carrier frame 1. 12 and the first guide frame 3 form a guiding structure and a connecting rod 30 is fixedly connected between the two. The upper end of the clamping drive mechanism 8 is provided with a lifting and moving mechanism 4, which is used to drive the clamping drive mechanism 8 to move. The guide structure is used to guide the moving path of the clamping drive mechanism 8. A flip assembly is provided on the second guide frame 12. The flip assembly is used to drive the anti-slip clamping foot 15 to rotate and thus complete the 180-degree rotation of the wooden pallet. The flip assembly includes a gear 18 and a tooth block 14. The lower end of the second guide frame 12 is fixedly connected to a fixed block 29. The interior of the fixed block 29 is provided with an adjustment assembly. The adjustment assembly is used to drive the position of the tooth block 14 to adjust;

[0031] The wooden pallet stacking device realizes precise flipping control of wooden pallets during the process of being transported to the carrier 1. When the first wooden pallet is clamped and transferred, the flipping component is activated, driving the pallet to complete a smooth flip of 180 degrees, ensuring that the first pallet is safely stacked with the panel facing down. During the clamping and transfer process of subsequent wooden pallets, the flipping component remains silent, maintaining the pallet support bar downward for stacking. This alternating pattern is repeated in the transfer of subsequent wooden pallets, that is, the flipping component responds intelligently once for each pallet, ensuring that the pallets can be stacked in a staggered manner. This design not only gives wooden pallets a high degree of flexibility in stacking operations, but also realizes the precise layout of pallet stacking through the intelligent control of the adjustment components, greatly optimizing space utilization efficiency, not only improving the efficiency of stacking operations, but also significantly enhancing the capacity and practicality of storage space, bringing significant efficiency improvements to the logistics and warehousing fields.

[0032] Further, such as Figure 2 As shown, the carrier frame 1 and the conveyor frame 6 are both fixedly connected with mounting rods 31, the upper ends of the two mounting rods 31 are fixedly connected to the lifting and moving mechanism 4, and the lower end of the lifting and moving mechanism 4 is fixedly connected to the first guide frame 3 through a connecting piece;

[0033] The carrier frame 1 and the conveyor frame 6 are both fixedly connected with mounting rods 31, and the upper ends of the two mounting rods 31 are firmly connected to the lifting and moving mechanism 4. This design ensures that the lifting and moving mechanism 4 has a solid support foundation and enhances the stability of the structure. The lifting and moving mechanism 4 is a prior art and the specific structure is not described in detail in the article. The lifting and moving mechanism is mainly composed of a driving device, a transmission mechanism and a sliding assembly. When the driving device is started, it transmits power to the sliding assembly through the transmission mechanism, driving the lifting and moving mechanism 4 to perform vertical and directional lifting and lowering movements along the path formed by the mounting rods 31 and the first guide frame 3. In this process, the lifting and moving mechanism 4 will drive the clamping driving mechanism 8 below it to move together, thereby realizing the clamping and lifting operations of the wooden pallet.

[0034] Further, such as Figures 1 to 5 As shown, both ends of one side of the upper end of the conveying frame 6 are fixedly connected to the guide plates 5, the guide plates 5 are arc-shaped, and the lower ends of the two splints 7 are engaged and rotatably connected to the limit block 16, and the anti-slip clamping foot 15 is fixedly connected to the end face of the limit block 16 on one side close to the wooden pallet, and one end of the limit block 16 on one side is fixedly connected to a square column 17, the cross section of the square column 17 is square, and one end of the square column 17 is slidably connected to the second guide frame 12, and the gear 18 in the flip assembly is fixedly connected to the end of the square column 17 away from the splint 7, and one end of the second guide frame 12 The side end surface is fixedly connected to a fixing plate 9, one end of the fixing plate 9 is fixedly connected to a limiting slot block 11, the inner portion of the limiting slot block 11 is slidably connected to a connecting rod 10, a tooth block 14 is fixedly connected to the upper end of the connecting rod 10, and the height position of the tooth block 14 is set between the first guide frame 3 and the second guide frame 12. When the gear 18 moves to the same height as the tooth block 14, it engages with the tooth block 14 and drives the square column 17 to rotate. Rounded corners 13 are provided on both sides of the upper end of the second guide frame 12 and on both sides of the lower end of the first guide frame 3 on the side of the second guide frame 12;

[0035] On one side of the upper end of the conveyor frame 6, arc-shaped guide plates 5 are fixedly connected at both ends. These guide plates 5 provide guidance for the movement of the wooden pallet. When it moves to the tail end of the conveyor frame 6, the baffle is blocked. At this time, the middle of the wooden pallet is just on one side of the anti-slip clamping foot 15. Since the clamping mechanism is an existing public technology, the structure is not explained in the article. The clamping structure is composed of a motor and a bidirectional screw rod. When the motor is started, the plywood 7 connected to the bidirectional screw rod moves closer or farther away from each other to complete the clamping and release of the wooden pallet. After the clamping mechanism drives the plywood 7 to complete the clamping of the wooden pallet, the limit block 16 on one side is connected to the gear 18 in the flip assembly through the square column 17. The cross-section of the square column 17 is square, which ensures that its sliding connection in the second guide frame 12 is stable and will not rotate. The lifting and moving mechanism 4 drives the clamping mechanism and then drives the movement of the wooden pallet, so that the square column 17 moves upward. When the square column 17 drives the gear 18 to move to the position aligned with the gear When the blocks 14 are at the same height, the gear 18 will mesh with the tooth block 14, and the tooth block 14 is slidably connected to the limit slot block 11 through the connecting rod 10, and the limit slot block 11 is fixed on the fixed plate 9. At this time, due to the meshing action of the gear 18 and the tooth block 14, the square column 17 will start to rotate, thereby driving the limit block 16 and the anti-slip clamping foot 15 connected thereto to rotate together. Since the anti-slip clamping foot 15 is fixedly connected to the end face of the limit block 16 on one side close to the wooden pallet, when the limit block 16 rotates, the anti-slip clamping foot 15 will also rotate accordingly, thereby driving the entire clamped wooden pallet to flip 180 degrees. Rounded corners 13 are provided between the first guide frame 3 and the second guide frame 12, as well as on both sides of the upper end of the second guide frame 12 and on both sides of the lower end of the first guide frame 3 on the side of the second guide frame 12. The design of these rounded corners 13 not only helps to reduce friction and wear, but also makes the movement of the wooden pallet smoother during the flipping process.

[0036] Further, such as Figures 3 to 7As shown, the adjustment assembly includes a resistance rod 21 slidably connected to the inside of the fixed block 29, one end of the resistance rod 21 passes through the fixed block 29 and is fixedly connected to the connecting rod 10, the adjustment assembly also includes a pressing column 24 slidably connected to the middle of the lower end of the second guide frame 12, a movable groove 33 inside the lower end of the second guide frame 12, the pressing column 24 is located in the middle of the movable groove 33 and is fixedly connected to the second spring seat 26 on both sides, one end of the two second spring seats 26 is fixedly connected to a card plate 32, and the end of the card plate 32 away from the second spring seat 26 is inclined, the middle of the inner wall of the movable groove 33 is fixedly connected to a fixing ring 25 near the upper end, and the inner wall of the movable groove 33 is fixed near the lower end. A retaining ring 28 is fixedly connected, and a sliding ring 23 is provided on the upper end of the retaining ring 28. The sliding ring 23 is slidably connected in the movable groove 33. The upper end face of the fixed ring 25 is inclined, and the lower end face of the sliding ring 23 is inclined. The lower end of the pressing column 24 extends into the fixed block 29 and is fixedly connected with the resistance block 22. The resistance block 22 is inclined on one side close to the resistance rod 21. The end of the resistance rod 21 close to the resistance block 22 is also inclined and is provided with a roller 27. The middle part of the outer wall of the resistance rod 21 is fixedly connected with a slider 19. The upper and lower ends of the slider 19 are fixedly connected to the first spring seat 20, and one end of the two first spring seats 20 is fixedly connected to the slider 19.

[0037] The adjusting assembly is mainly composed of a resisting rod 21, a pressing column 24, a sliding ring 23, a fixed block 29, a connecting rod 10, a tooth block 14 and related spring seats, clamping plates 32 and other components. These components work together to trigger the adjusting assembly by squeezing the square column 17, thereby achieving precise control of the flipping behavior of the flipping assembly. During the stacking operation, every time the stacking work of a wooden pallet is completed, the square column 17 will move to the lower end of the second guide frame 12 under the drive of the lifting and moving mechanism 4, and squeeze the pressing column 24. The pressing column 24 moves downward in the movable groove 33, which can achieve the effect of driving the connecting rod 10 to move together. The upper end of the connecting rod 10 is fixedly connected to the tooth block 14, and the tooth block 14 is restricted in the limit groove and can slide backward along the limit groove. When the pressing column 24 is squeezed by the square column 17, the connecting rod 10 will drive the tooth block 14 to slide backward in the limiting groove, thereby changing the position of the tooth block 14. At this time, if the gear 18 in the flip assembly moves to the same height as the tooth block 14, since the position of the tooth block 14 has changed, the gear 18 will not mesh with the tooth block 14, so the flip assembly will not work and the wooden pallet will not flip. When the square column 17 completes a stacking work and returns, it will squeeze the pressing column 24 again. At this time, the pressing column 24 realizes the reset work of the connecting rod 10 through the structure inside the movable groove 33. When the connecting rod 10 is located at the end of the limiting slot block 11 away from the tooth block 14, the gear 18 will not be meshed with the gear 18, and the card in the pressing column 24 When the plate 32 is located between the fixed ring 25 and the limit ring, when the square column 17 returns and presses the pressing column 24 again, the card plate 32 moves downward and one end of its inclined surface contacts the sliding ring 23 and contracts inwardly through the second spring seat 26. When the card plate 32 moves to the lower end of the sliding ring 23, the pressing column 24 drives the sliding ring 23 to rise under the elastic force of the first spring seat 20. After the sliding ring 23 contacts the fixed ring 25, it cannot rise anymore. Because the lower end of the sliding ring 23 is inclined, the card plate 32 will contract inwardly again, and then pass through the fixed ring 25 and the sliding ring 23. After passing, the card plate 32 rebounds and is located at the upper end of the fixed ring 25. At this time, the position of the interference block 22 has been moved up, and the interference rod 21 also moves forward under the elastic force of the first spring seat 20. The pallet is then moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved back and forth in a direction of rotation, and the square column 17 is moved
