Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storage, in particular to a stacking device for warehouse logistics. BACKGROUND

[0002] With the rapid development of the logistics industry, the storage of materials in warehouses has also developed rapidly. In the traditional warehouse storage method, materials are stacked on the ground of the factory building. However, due to the stacking height of the materials, the materials are not usually stacked too high, so a larger warehouse is needed to store the materials. Now, shelves are built in the warehouse, and the shelves are usually several meters to several tens of meters high. Each layer of the shelf has multiple storage compartments for placing materials.

[0003] In related technologies, a chain roller conveyor is arranged between two adjacent shelves, a movable frame that can slide is arranged along the movement direction of the chain roller conveyor, a plugboard that can be lifted and lowered is arranged in the movable frame, and the plugboard is used to insert and take the pallet below the material. The chain roller conveyor is used to convey the material to the movable frame, the plugboard is driven to descend, the plugboard is inserted into the pallet, the plugboard is driven to ascend, the plugboard lifts the pallet, when the material placement position is reached, the plugboard is rotated to face the compartment where the material is placed, the plugboard is driven to put the material into the compartment and lower it, then the plugboard is taken out of the pallet and rotated back to the original position.

[0004] When the material in the compartment needs to be taken out and new material needs to be placed in the compartment, the pallet is used to take out the material in the compartment and place the material on the chain roller conveyor, the chain roller conveyor is used to convey the material to the material taking and placing end, the forklift is used to take away the material, then the forklift is used to place the new material on the chain roller conveyor, and the chain roller conveyor is used to convey the material to the movable frame and place the new material in the compartment. When the materials are exchanged, the previous material is unloaded through the plugboard and the chain roller conveyor, and then the new material is loaded through the chain roller conveyor and the plugboard. This makes the taking and placing efficiency between the materials low, and the subsequent unloading and loading cannot be performed until the loading and unloading operations are completed. SUMMARY

[0017] In summary, the present application has at least one of the following beneficial technical effects:

[0018] 1. The upper material is conveyed by the upper chain roller conveyor, and the lower material is conveyed by the upper chain roller conveyor, the lifting chain roller conveyor and the lower chain roller conveyor. The material does not need to be conveyed by a single chain roller conveyor. The upper material and the lower material are conveyed separately, which improves the material conveying efficiency. When the lower material is inserted, the upper material is inserted at the same time, which improves the material taking efficiency. In order to accurately insert the lower material into the hole of the tray, the top surface of the lower material needs to be lower than the top surface of the hole. When the lower material is inserted into the hole, the lower material is lifted slightly, and the lower material is lifted slightly. The upper material is lowered slightly, and the top surface of the upper material is lower than the top surface of the hole. The lower material is driven to recover, and the tray is taken out. The rotary frame is rotated by 90°, and the upper material is inserted into the hole at the same time. The lower material is lowered, and the upper material is lifted to realize the bidirectional operation of the upper material and the lower material. When the lower material is placed on the top surface of the upper chain roller conveyor, the upper material reaches the specified position. The rotary frame is driven to rotate by 90°, and the upper material is driven to send the tray into the compartment. The upper material is lowered slightly, and the tray is placed. The upper material is separated from the tray. The upper material is recovered and rotated by 90°, and then it is lowered. At this time, the lower material is also lifted slightly, and it is always lifted to realize the position exchange of the upper material and the lower material. The upper material and the lower material can be used separately through the cooperation of the upper material and the lower material.

[0019] 2. When the connection between the rotating shaft and the rotating shaft is realized through the connecting mechanism, the rotation of the two rope winding discs is synchronous. When one of the rope winding discs rotates, the rope winding disc drives the rotating shaft to rotate through the rotating shaft, the rotating shaft drives the sprocket to rotate, the sprocket drives the other sprocket to rotate through the chain, the sprocket drives the rotating shaft to rotate, and the rotating shaft drives the other rope winding disc to rotate through the rotating shaft. When the upper material and the lower material are inserted into the tray at the same time, the gravitational potential energy generated by the material on the lower material can drive the material on the upper material to rise, and the additional kinetic energy is generated by the lifting motor for lifting the upper material.

[0020] 3. When the two rope winding discs need to be connected, the electric push rod drives the connecting plate to move, the connecting plate drives the sliding pipe to move towards the sprocket, the first spline shaft located in the annular groove enters the first spline groove, the connection between the rotating pipe and the rotating shaft is realized, the sliding block slides in the sliding groove, and the connection between the rotating pipe and the sliding pipe is maintained. At this time, the connection between the rotating shaft and the rotating shaft is realized, and the connection between the two rope winding discs can be realized. When the two rope winding discs do not need to be connected, the electric push rod drives the connecting plate to move back, the connecting plate drives the sliding pipe to move back, and the first spline shaft enters the annular groove. At this time, the first spline shaft is not connected with the rotating pipe, and the first spline shaft rotates in the annular groove. BRIEF DESCRIPTION OF DRAWINGS

The discharging plug-in plate 4 is lowered, and the feeding plug-in plate 3 holds up the tray 02 and rises, realizing the bidirectional operation of feeding and discharging. When the discharging plug-in plate 4 places the tray 02 on the top surface of the upper chain roller conveyor 11, the feeding plug-in plate 3 reaches the specified position, the rotating frame 26 is driven to rotate 90°, the feeding plug-in plate 3 is driven to send the tray 02 into the compartment, the feeding plug-in plate 3 is lowered slightly, the tray 02 is placed, and the feeding plug-in plate 3 is separated from the tray 02. The feeding plug-in plate 3 is retracted and rotated 90°, and then lowered. At this time, the discharging plug-in plate 4 is also raised slightly, and then continuously rises, realizing the position exchange of the feeding plug-in plate 3 and the discharging plug-in plate 4. Through the cooperation of the feeding plug-in plate 3 and the discharging plug-in plate 4, the efficiency of feeding and discharging the materials 01 can be improved, and the feeding plug-in plate 3 and the discharging plug-in plate 4 can also be used separately.
