Description

Technical Field

[0001] The present invention relates to the field of palletizing, and particularly to an automatic palletizing device for shelf shelves. Background Art

[0002] At present, in most shelf factories, after the shelves are formed, most of them adopt the method of manual palletizing or robotic arm palletizing. The defect of manual palletizing is that each production line needs to be equipped with a worker for a long time, resulting in high labor costs. The defect of robotic arm palletizing is that it is difficult to debug and has high maintenance costs. It cannot simply handle various different specifications of shelves, and it is very costly for existing enterprises to find a worker who can debug robotic arms separately. At the same time, the existing shelves have extension parts that extend obliquely along the edges of the shelves. If stacked layer by layer in a conventional manner, this method is prone to problems such as unstable palletizing and easy collapse. Summary of the Invention

The first rotating frame 20 rotates 90°, changing the layer board from vertical to horizontal, and then places it on the first conveyor 22. The first layer board enters the second conveyor 2 from the first conveyor 22.

The two third cylinders 7 respectively drive the mounting frames 5 to move towards each other, making the two clamping arms 11 approach each other. The second layer board moves towards the second conveyor 2 and enters between the grooves 12 of the two clamping arms 11. The lifting platform 4 moves upward under the drive of the second cylinder 6. The piston rod of the second cylinder 6 extends, driving the lifting platform 4 to move upward. The lifting platform 4 drives the mounting frame 5 to move upward, and the mounting frame 5 drives the clamping arms 11 to move upward. The piston rod of the fourth cylinder 8 retracts, pulling the rack 10 to move. At the same time, the gear 9 moves on the rack 10, and the two clamping arms 11 are driven by the gear 9 to flip, driving the second layer board to flip 180°, stacking the second layer board on the first layer board. The first servo motor 14 drives the frame 13 to move horizontally to the output end of the second conveyor 2. The second servo motor 15 drives the second rotating frame 16 to move downward, and the gripper 17 on the second rotating frame 16 picks up the first layer board and the second layer board as a whole. The first servo motor 14 drives the frame 13 to move horizontally to the position of the tray 29, and the second servo motor 15 drives the second rotating frame 16 to move downward, placing the first layer board and the second layer board as a whole layer board on the tray 29 together.

[0040] Among them, the palletizing method of this embodiment is that the first layer board and the second layer board are combined into a whole layer board. The whole layer board is placed horizontally, and the two upper layer boards are rotated 90° and placed vertically. Stacked in this staggered manner, that is, after the gripper 17 of the second rotating frame 16 picks up the whole layer board, the first whole layer board and the second whole layer board are placed horizontally on the tray 29. After the second rotating frame 16 picks up the third whole layer board and the fourth whole layer board respectively and rotates 90°, they are stacked above the first whole layer board and the second whole layer board.
