Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, and in particular to a pallet stacking mechanism. Background Technology

[0002] Pallets are horizontal platform devices used for the containerization, stacking, handling, and transportation of goods and products as unit loads. As a type of containerization equipment similar to containers, pallets are now widely used in production, transportation, warehousing, and distribution. They are considered one of the two key innovations in the logistics industry in the 20th century. As an important loading, unloading, storage, and transportation equipment in logistics operations, pallets play a huge role in modern logistics when used in conjunction with forklifts.

[0003] During pallet handling, destacking (separating stacked pallets one by one) and stacking (neatly stacking single or multiple pallets) operations are frequently required. While some semi-automatic or automatic pallet destacking and stacking devices exist, they generally suffer from complex structures, cumbersome operations, low positioning accuracy, or poor clamping stability. More commonly, pallet destacking and stacking operations still rely primarily on manual labor. Manual destacking and stacking is not only labor-intensive and inefficient, failing to meet the demands of modern logistics for high efficiency and continuous operation, but also poses safety hazards when handling heavy pallets. Especially in applications requiring precise pallet positioning, lifting, and stable clamping for reliable destacking and stacking, existing solutions are often costly or ineffective. Therefore, there is an urgent need for a destacking and stacking mechanism that is structurally sound, easy to operate, accurately positioned, securely clamped, and highly automated to significantly improve the efficiency and safety of pallet destacking and stacking operations and reduce manual intervention. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a mechanism for disassembling and stacking trays.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a tray stacking mechanism, including a frame, and also including...

[0007] The mounting components include crossbeams symmetrically arranged on both sides of the frame, a limiting plate connected to the crossbeams via a connecting plate, and a stacking channel located between the opposing limiting plates.

[0008] A conveying assembly for conveying the pallet below the destacking channel;

[0009] A lifting assembly for lifting the conveying assembly to convey the pallet into the destacking channel;

[0010] The folding assembly includes clamping parts disposed on both sides of the crossbeam for clamping the tray, a rotating part connected to the clamping parts, a linkage part connecting the two rotating parts, and a power part for driving one of the rotating parts to rotate to realize the movement of the two clamping parts.

[0011] Furthermore, the rotating part includes bearing seats distributed vertically on the crossbeam, a bearing disposed on the bearing seats, a rotating shaft with both ends connected to the inner rings of the bearings respectively, and a rectangular sleeve disposed outside the rotating shaft.

[0012] Furthermore, the clamping part includes an extension plate connected to the rectangular sleeve and an insert plate passing through an inclined plate and the extension plate.

[0013] Furthermore, it also includes a reinforcing plate connecting the extension plate and the rectangular sleeve.

[0014] Furthermore, the linkage includes connecting plates disposed on the two rectangular sleeves, a first support shaft connected to one end of the connecting plates, a first U-shaped plate rotatably connected to both ends of the first support shaft, and a connecting rod connecting the two first U-shaped plates.

[0015] Furthermore, the power unit includes a fixed plate mounted on the frame, a support plate distributed vertically on the fixed plate, a cylinder rotatably connected to the support plate, a second U-shaped plate connected to the cylinder, a lug provided on the rectangular sleeve, and a second support shaft provided on the lug and rotatably connected at both ends to the second U-shaped plate.

[0016] Furthermore, the lifting assembly includes a frame fixed to the bottom of the conveying assembly, four U-shaped frame plates symmetrically distributed at the bottom of the frame, rollers slidably connected inside the U-shaped frame plates, a crank arm connected to one end of the roller, a drive shaft connected to the two crank arms at both ends respectively, a bearing seat provided at the bottom of the frame for supporting the drive shaft, a first sprocket provided on the drive shaft, a second sprocket connected to the first sprocket via a chain, and a motor for driving the second sprocket to rotate.

[0017] The stacking mechanism proposed in this utility model has the following advantages:

[0018] This invention uses a conveying component to transport a pallet to the area directly below the stacking channel. A lifting component raises the conveying component, allowing the pallet to enter the stacking channel. A power unit drives a rotating unit, which in turn drives the clamping units on both sides to clamp the pallet, thus achieving automatic positioning, lifting, clamping, and stacking of the pallet. This reduces manual intervention and improves work efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example, refer to Figures 1-3 A stacking and unstacking mechanism includes a frame 1, and further includes...

[0024] The mounting assembly 2 includes crossbeams 201 symmetrically arranged on both sides of the frame 1, a limiting plate 203 connected to the crossbeams 201 via a connecting plate 202, and a stacking channel 204 located between the opposing limiting plates 203. Preferably, in this embodiment, guide plates 205 can be provided at both ends of the limiting plate 203. The guide plates 205 at both ends of the limiting plate 203 are inclined in a direction away from the stacking channel 204, which is used to guide the movement of the pallet 4 so that the pallet 4 can quickly enter the stacking channel 204.

[0025] The conveying assembly 3 is used to convey the pallet 4 to the area below the stacking channel 204. Preferably, the conveying assembly 3 in this embodiment is a roller conveyor, which is prior art and will not be described in detail here.

[0026] Lifting assembly 5, which is used to lift conveying assembly 3 to convey pallet 4 into stacking channel 204;

[0027] The folding assembly 6 includes a clamping part 601 disposed on both sides of the crossbeam 201 for clamping the tray 4, a rotating part 602 connected to the clamping part 601, a linkage part 603 connecting the two rotating parts 602, and a power part 604 for driving one of the rotating parts 602 to rotate so as to realize the action of the two clamping parts 601.

[0028] This invention uses a conveying component 3 to transport a pallet 4 directly below a stacking channel 204. A lifting component 5 raises the conveying component 3, allowing the pallet to enter the stacking channel 204. A power unit 604 drives a rotating unit 602, which in turn drives two clamping units 601 on both sides to clamp the pallet via a linkage unit 603. This achieves automatic positioning, lifting, clamping, and stacking of the pallet, reducing manual intervention and improving work efficiency.

[0029] In an optional embodiment of this utility model, the rotating part 602 includes a bearing seat 6021 distributed vertically on the crossbeam 201, a bearing 6022 disposed on the bearing seat 6021, a rotating shaft 6023 whose two ends are respectively connected to the inner ring of the bearing 6022, and a rectangular sleeve 6024 disposed outside the rotating shaft 6023. The rotating shaft 6023 rotates within the bearing seat 6021 through the bearing 6022. The rectangular sleeve 6024 transmits the rotational motion to the clamping part 601. The bearing 6022 provides support to reduce friction and ensure smooth rotation. The rectangular sleeve 6024 provides a rigid connection to prevent clamping deviation.

[0030] In an optional embodiment of this utility model, the clamping part 601 includes an extension plate 6011 connected to the rectangular sleeve 6024 and an insert plate 6013 connected to the inclined plate 6012 and the extension plate 6011. In this embodiment, the insert plates 6013 of the clamping part 601 provided on the same crossbeam 201 have opposite length extension directions to ensure that the two clamping parts 601 can be inserted into the tray 4 synchronously when they move. The oppositely extending insert plates 6013 achieve symmetrical clamping, avoid uneven force on the tray, and the insert plates 6013 are directly inserted into the grooves on both sides of the tray to improve clamping stability.

[0031] In an optional embodiment of this utility model, a reinforcing plate 6014 is also included to connect the extension plate 6011 and the rectangular sleeve 6024. The reinforcing plate 6014 can enhance the rigidity of the clamping part 601, prevent structural deformation under high-frequency operation, and reduce fatigue damage.

[0032] In an optional embodiment of this utility model, the linkage part 603 includes a connecting plate 6031 disposed on two rectangular sleeves 6024, a first support shaft 6032 connected to one end of the connecting plate 6031, a first U-shaped plate 6033 rotatably connected to both ends of the first support shaft 6032, and a connecting rod 6034 connecting the two first U-shaped plates 6033. In this embodiment, the length extension directions of the two connecting plates 6031 are perpendicular to each other, so that the two rotating parts 602 can drive the clamping parts 601 to move closer or further away synchronously, thereby realizing the stacking and unstacking of multiple trays 4.

[0033] In an optional embodiment of this utility model, the power unit 604 includes a fixed plate 6041 mounted on the frame 1, a support plate 6042 distributed vertically on the fixed plate 6041, a cylinder 6043 rotatably connected to the support plate 6042, a second U-shaped plate 6044 connected to the cylinder 6043, a lug 6045 provided on the rectangular sleeve 6024, and a second support shaft 6046 provided on the lug 6045 and rotatably connected at both ends to the second U-shaped plate 6044. The cylinder 6043 pushes the second U-shaped plate 6044, which drives the lug 6045 to rotate via the second support shaft 6046, thereby driving the rotating part 602 to operate.

[0034] In an optional embodiment of this utility model, the lifting assembly 5 includes a frame 501 fixed to the bottom of the conveying assembly 3, four U-shaped frame plates 502 symmetrically distributed at the bottom of the frame 501, rollers 503 slidably connected inside the U-shaped frame plates 502, a crank arm 510 connected to one end of the roller 503, a drive shaft 504 connected to two crank arms 510 at each end, a bearing seat 505 provided at the bottom of the frame 1 for supporting the drive shaft 504, a first sprocket 506 provided on the drive shaft 504, and a chain. The second sprocket 508, which is connected to the first sprocket 506, and the motor 509, which drives the second sprocket 508 to rotate, are fixed to the bottom of the frame 1 by bolts in this embodiment. The motor 509 drives the second sprocket 508 to rotate, and the first sprocket 506 is rotated synchronously through the chain 507, so that the two drive shafts 504 rotate synchronously. This causes the crank arm 510 to rotate and drive the roller 503 to slide in the U-shaped frame plate 502, thereby realizing the lifting and lowering of the frame 501 and the conveying assembly 3.
