Description

Technical Field

[0001] This utility model relates to the field of palletizing device technology, and in particular to a pallet palletizing device. Background Technology

[0002] In automated production lines, pallet palletizing devices are key equipment for the efficient handling and stacking of pallets, and are widely used in goods storage, transportation, and palletizing operations. Traditional pallet palletizing devices typically use a single lifting or conveying mechanism to lift and move pallets, but in practical applications, they suffer from problems such as insufficient lifting stability, complex structure, high maintenance costs, and low power and transmission efficiency.

[0003] To address the aforementioned issues, some improvements have been implemented in the existing technology, such as employing a dual lifting mechanism or adding a guiding device. However, problems still exist, such as unreasonable guide structure design, which may increase friction between the pallet and the device and affect the smoothness of operation.

[0004] Therefore, there is an urgent need for a pallet palletizing device that is structurally stable, highly synchronized, adaptable, and easy to maintain, in order to improve palletizing efficiency, reduce failure rate, and meet the needs of modern logistics automation. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a pallet palletizing device that can operate continuously and repeatedly, thereby improving palletizing efficiency.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a pallet stacking device, including a conveying section, a stacking section, a frame, a lifting component and a trolley. The frame is provided with a first lifting section and a second lifting section, which are symmetrically arranged on both sides of the width direction of the conveying section. The first lifting section and the second lifting section are designed to surround each other. The lifting component includes a linkage component, and the two ends of the linkage component are respectively connected to the first lifting section and the second lifting section. The side of the linkage component near the center direction of the frame is connected to an assembly. The assembly component is provided with a rotating shaft and a limiting rod. The two ends of the limiting rod are provided with mounting seats, and the mounting seats are rotatably connected to the rotating shaft.

[0007] Preferably, the first and second lifting parts are chain structures, and a rotating motor is provided on the frame. The output end of the rotating motor is connected to a main shaft, and the main shaft is connected to a secondary shaft through gears and chains. The first and second lifting parts are respectively connected to the secondary shafts through gears and chains.

[0008] Preferably, the conveying section is a chain conveying mechanism, and guide plates are provided on both sides of the conveying section in the width direction.

[0009] Preferably, the first lifting section and the second lifting section are arranged alternately.

[0010] Preferably, the linkage is a Z-shaped component.

[0011] Preferably, a limit plate is provided on the side of the frame located in the output direction of the conveying section.

[0012] Preferably, the frame is also provided with a guide frame.

[0013] Preferably, the lower part of the support member has an arc-shaped structure, and the curvature of the side closer to the center of the frame relative to the pivot is greater than that of the side farther from the center of the frame.

[0014] Preferably, the lifting components are arranged in an array on the first lifting section and the second lifting section.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0016] 1. By setting up a first and second lifting section that surrounds the palletizer, uninterrupted operation of palletizing can be achieved, thus improving palletizing efficiency;

[0017] 2. By setting up multiple sets of lifting components, palletizing efficiency can be further improved;

[0018] 3. By staggering the first and second lifting sections and cooperating with Z-shaped parts, the stability during pallet conveying can be improved;

[0019] 4. By setting a limit rod on the mounting base, the upper edge of the support can be kept horizontal when the tray is placed;

[0020] 5. By setting a rotatable support, when the pallet is transferred to the side of the trolley and touches the trolley or has been placed on the pallet, the support rotates, the pallet is unloaded, and the support continues to move downward until it is detached from the trolley, and can automatically return to its original state.

[0021] 6. By setting the support component to an arc shape with a greater curvature on the side closer to the center of the frame relative to the pivot than on the side farther from the frame, the weight on the side closer to the frame relative to the pivot is greater than the weight on the side farther from the frame, so that it can automatically return to its initial state after the operation is completed and continue to support the pallet.

[0022] 7. Driven by a rotating motor, it can save electricity while ensuring the synchronization of the left and right first and second lifting sections.

[0023] 8. By installing guide plates on the conveyor section, the pallet can be corrected in advance, reducing the possibility of the support components failing to provide support;

[0024] 9. By setting a guide frame, the pallet can be automatically kept parallel to the conveying direction of the conveyor when it is placed, and the stability of the pallet is good after it is placed. Attached Figure Description

[0036] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0037] Example 1

[0038] See Figures 1 to 8A pallet stacking device includes a conveying section 1 and a stacking section 2, wherein the stacking section 2 is a stacker crane. It also includes a frame 3, a lifting assembly 4, and a trolley 5. The frame 3 is provided with a first lifting section 31 and a second lifting section 32, which are symmetrically arranged on both sides of the conveying section 1 in the width direction. The first lifting section 31 and the second lifting section 32 are arranged in a ring-shaped design. The lifting assembly 4 includes a linkage component, the two ends of which are respectively connected to the first lifting section 31 and the second lifting section 32. A mounting part 42 is connected to the side of the linkage component near the center of the frame 3. The mounting part 42 is provided with a rotating shaft 421 and a limiting rod 422. Mounting seats 43 are provided at both ends of the limiting rod 422, and support members 44 are rotatably connected to the rotating shaft 421 on the mounting seats 43.

[0039] like Figure 3 and Figure 5 As shown, the first lifting part 31 and the second lifting part 32 are chain structures. A rotating motor 33 is provided on the frame 3. The output end of the rotating motor 33 is connected to the main shaft 331. The main shaft 331 is connected to the secondary shaft 332 through gears and chains. The first lifting part 31 and the second lifting part 32 are respectively connected to the secondary shaft 332 through gears and chains.

[0040] like Figure 1 , Figure 3 and Figure 7 As shown, the conveying section 1 is a chain conveying mechanism, and guide plates 101 are provided on both sides of the conveying section 1 in the width direction.

[0041] like Figure 2 and Figure 3 As shown, the first lifting part 31 and the second lifting part 32 are arranged alternately.

[0042] like Figure 6 As shown, the linkage component is a Z-shaped component 41.

[0043] like Figure 7 and Figure 9 As shown, a limit plate 6 is provided on the side of the frame 3 located in the output direction of the conveying section 1.

[0044] like Figure 7 and Figure 10 As shown, a guide frame 7 is also provided on the frame 3.

[0045] like Figure 8 As shown, the lower part of the support member 44 has an arc-shaped structure, and the curvature of the side closer to the center of the frame 3 relative to the pivot 421 is greater than that of the side farther from the center of the frame 3.

[0046] The lifting components 4 are arranged in an array on the first lifting part 31 and the second lifting part 32.

[0047] Working principle

[0048] This pallet palletizing device achieves efficient and stable pallet palletizing through the coordinated operation of its components. The overall design uses a first lifting section 31 and a second lifting section 32 arranged in a circular pattern as the core transmission structure, which, together with multiple arrayed lifting components 4, completes the lifting and transfer of pallets. The specific principle is as follows:

[0049] The conveying unit 1 is responsible for transporting the pallets to be stacked to the lifting area. The guide plates 101 on both sides of the unit will pre-correct the position of the pallets to ensure that the pallets accurately enter the working range of the lifting assembly 4. When the pallet is transported to the designated position, the support member 44 in the lifting assembly 4 receives the pallet. Since the mounting base 43 is equipped with a limit rod 422, the support member 44 keeps its upper edge horizontal at this time, stably supporting the pallet.

[0050] The first lifting section 31 and the second lifting section 32 are driven by the same rotating motor 33. They achieve synchronous operation through the linkage of the main shaft 331, gears, chains, and the secondary shaft 332. The two are staggered and cooperate with Z-shaped linkage components to improve the stability during pallet transportation. The first and second lifting sections, which are designed to surround each other, drive the lifting assembly 4 to perform cyclical motion, realizing uninterrupted operation of palletizing.

[0051] During the transfer of the pallet to one side of the frame 5, when the support member 44 touches the frame 5 or the pallet already placed, the support member 44 will rotate around the pivot 421, allowing the pallet to be smoothly unloaded. The lower part of the support member 44 has an arc-shaped structure, and the curvature of the side closer to the center of the frame 3 relative to the pivot 421 is greater than that of the side farther away. This makes the side closer to the center of the frame 3 heavier. After the operation is completed, the support member 44 can automatically return to its initial state and continue to support the next pallet.

[0052] The guide frame 7 on the frame 3 automatically keeps the pallet cart 5 parallel to the conveying direction of the conveyor 1 when it is placed in, ensuring the stability of the pallet after placement; the limiting plate 6 restricts the conveying position of the pallet, further ensuring the accuracy of the operation. The lifting components 4, arranged in multiple arrays, further improve the palletizing efficiency.

[0053] Specific operating methods

[0054] Device startup: Start the device, rotate the motor 33 to start working, drive the first lifting part 31 and the second lifting part 32 to operate synchronously through the main shaft 331, gears, chain and secondary shaft 332, and the lifting component 4 will circulate with it. At this time, the support 44 is in the initial upper edge horizontal state, waiting to receive the pallet.

[0055] Placement of the pallet 5: Place the pallet 5 into the designated position on the frame 3 via the guide frame 7. Under the action of the guide frame 7, the pallet 5 automatically keeps parallel to the conveying direction of the conveying unit 1, ensuring the stability of subsequent pallet placement.

[0056] Placing the pallet: Place the pallet to be stacked on the conveyor section 1. The pallet is conveyed forward by the chain conveyor mechanism. During the conveying process, the guide plates 101 on both sides correct the pallet to ensure that the pallet moves accurately in the direction of the lifting component 4.

[0057] Pallet reception and lifting: When the pallet is transported to the lifting assembly 4, it is received by the support member 44. Due to the action of the limiting rod 422, the support member 44 keeps its upper edge horizontal, stably supporting the pallet. Driven by the first lifting part 31 and the second lifting part 32, the lifting assembly 4 moves upward, lifting the pallet.

[0058] Pallet transfer and placement: The lifting assembly 4, carrying the pallet, continues to move with the first and second lifting parts, transferring it to one side of the frame 5. When the support member 44 touches the frame 5 or the pallet already placed on the frame 5, the support member 44 rotates around the pivot 421, and the pallet is smoothly placed onto the frame 5.

[0059] Support component 44 resets: After the pallet is removed, the support component 44 rotates, ensuring that it continues to move downwards unaffected by the pallet. It continues to move downwards until it detaches from the frame 5. Due to its own structural characteristics (the side closer to the center of the frame 3 has a greater weight), it automatically returns to its initial state and continues to participate in the receiving operation of the next pallet.

[0060] Continuous operation: Under the action of the first and second surrounding lifting sections, multiple sets of lifting components 4 operate in cycles, continuously transferring pallets from the conveyor section 1 to the pallet rack 5, achieving efficient palletizing. If multiple layers of pallets need to be stacked, the device will repeat the above-mentioned receiving, lifting, transferring, and placing process until the pallet rack 5 is full.

[0061] Stopping and Retrieving the Cart: Once cart 5 is full of pallets, shut down the device and remove cart 5 from the frame 3 to complete one stacking operation. To continue stacking, repeat the above steps.

[0062] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
