Description

Technical Field

[0001] This utility model relates to the field of pallet technology, specifically to a pallet stacking device. Background Technology

[0002] On an assembly line, items are placed on pallets and transported between different workstations using conveyor rollers. Generally, buffer positions are required. Existing buffer positions use a long roller conveyor, and the conveyor speed is adjusted to meet the needs of buffering pallets. For example, pallets... Figure 1 As shown, it requires a large workshop area and has a limited scope of application. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a pallet stacking device that can easily achieve pallet stacking and buffering while occupying less workshop space.

[0004] The technical solution is as follows: a stacking device, characterized in that it includes a main support, a conveying roller device is arranged in the middle of the main support, a liftable lifting frame is arranged in the gap between the conveying rollers of the conveying roller device, side supports are installed on both sides of the conveying roller device, a lower centering mechanism and an upper support mechanism are installed on the side supports, the lower centering mechanism includes two symmetrically arranged centering cylinders and a centering pressure plate installed on the piston rod of the centering cylinder, the upper support mechanism includes two symmetrically arranged support electric cylinders and support bars installed on the push rod of the support electric cylinder, support blocks are arranged at intervals on the support bars, and guide columns are connected to both ends of the support bars, the guide columns are slidably engaged with guide seats on the side supports.

[0005] A further feature is that the lifting frame is provided with a positioning pin; A blocking cylinder is provided at the front end of the side bracket, and a blocking block is installed on the piston rod of the blocking cylinder.

[0006] By adopting this utility model, the pallet on the conveyor roller can be lifted by the lifting frame, and then the support bar can be extended under the pallet by the support electric cylinder to provide support. The pallets are stacked in the height direction for buffering. The overall structure is compact and occupies little area. Attached Figure Description

Detailed Implementation

[0008] See Figure 2 and Figure 3 As shown, a pallet stacking device includes a main support 1, a conveyor roller device 2 is arranged in the middle of the main support 1, and a lifting frame 3 is arranged in the gap between the front and rear conveyor rollers of the conveyor roller device. The lifting frame 3 is raised and lowered by a lifting drive mechanism at the bottom (which can be a synchronous lifter). When lowering, it can be lower than the conveyor rollers. Side supports 4 are installed on both sides of the conveyor roller device 2. A lower centering mechanism and an upper support mechanism are installed on the side supports 4. The lower centering mechanism includes two symmetrically arranged centering cylinders 5 and a centering pressure plate 6 installed on the piston rod of the centering cylinders 5. The two centering cylinders 5 synchronously drive the centering pressure plate 6 to move inward, so that the pallets can be centered. The upper support mechanism includes two symmetrically arranged support electric cylinders 7 and support bars 8 installed on the push rod of the support electric cylinders 7. The two ends of the support bars 8 are connected to guide columns 9. The guide columns 9 slide with guide seats 10 on the side supports. Support blocks 11 are arranged at intervals on the support bars 8.

[0009] The lifting frame 3 is equipped with a positioning pin 12, which can be inserted into the opening at the bottom of the tray to achieve positioning.

[0010] A blocking cylinder 13 is provided at the front end of the side support 4. A blocking block 14 is installed on the piston rod of the blocking cylinder 13 to prevent the tray from moving forward and to block it.

[0011] The working principle is as follows: When the first pallet enters the conveyor roller and reaches above the lifting frame 3, the blocking cylinder 13 drives the blocking block 14 to extend and block it. Then, the centering pressure plate 6 moves to the center to center the pallet and resets. Then, the lifting frame 3 rises, lifting the pallet together and leaving the conveyor roller. When the side ribs of the pallet (such as...) Figure 4 When the support bar 8 is higher than the area indicated by the red box, the lifting frame 3 stops, and the support cylinder 7 drives the support bar 8 to extend inward synchronously, so that the support block 8 on the support bar is below the side rib. The lifting frame 3 then descends, allowing the pallet to be supported on the side rib, completing the buffering of the first pallet. The lifting frame 3 then resets, waiting for the second pallet to arrive. After the second pallet arrives, it is also aligned first and then lifted by the lifting frame 3 until the second pallet touches the first pallet. At this point, the support cylinder 7 drives the support bar 8 to retract outward, and the lifting frame lifts both pallets together until the side rib of the second pallet is higher than the support bar 8. The lifting frame 3 then stops, and the support cylinder 7 drives the support bar 8 to extend inward synchronously to below the side rib of the second pallet. The lifting frame 3 then descends, allowing the two stacked pallets to be supported on the support bar 8, completing the buffering of the two pallets. The lifting frame 3 then resets, waiting for the third pallet to arrive. Subsequent pallets requiring buffering can be stacked and buffered in the same way.

[0012] When a buffer pallet needs to be removed, the lifting frame 3 rises until it touches the bottom of the lowest pallet. Then, the support cylinder 7 drives the support bar 8 to retract outwards, and the lifting frame 3 begins to descend. When the side rib of the second pallet is about to be lower than the support bar 8, the support cylinder 7 drives the support bar 8 to extend inwards to below the side rib of the second pallet, and the lifting frame 3 continues to descend, allowing the lowest pallet to fall onto the conveyor rollers together, while the remaining pallets remain supported above. Subsequent pallet removal operations are performed as described above, removing them one by one starting from the lowest layer.
