Several vacuum suction nozzles 7.4 connected to the air source are installed on the adsorption plate, and the vacuum suction nozzle 7.4 reciprocates between the interlayer warehouse 7.5 and the rotary drive.

[0032] The working principle of the present invention is: after the packaged cannon mud reaches the initial position of the palletizer through the conveyor line, the pusher lifting cylinder 3.7 drives the lifting pusher plate 3.8 to descend, the pusher reduction motor 3.2 drives the paint driving sprocket 3.3 with the pusher driving chain 3.4, so that the pusher bracket 3.1 moves horizontally, and the lifting pusher plate 3.8 pushes the arranged cannon mud materials to the temporary storage rack 4, and then the pusher lifting cylinder 3.7 drives the lifting pusher plate 3.8 to rise, the pusher reduction motor 3.2 drives the pusher driving sprocket 3.3 with the driving chain 3.4 to move the pusher bracket 3.1 to the initial position, at this time, the next batch of arranged materials is ready, and the pusher mechanism 3 pushes the materials to the temporary storage rack 4. After reaching the required quantity, the pusher mechanism 3 pushes all the arranged materials on the temporary storage rack 4 to the feeding mechanism 2.6 on the lifting mechanism 2 at one time.

[0033] After the feeding loading tray 2.6.6 of the feeding mechanism 2.6 receives the material, the feeding driving sprocket 2.6.3 on the feeding driving shaft 2.6.2 is driven to rotate by the feeding reduction motor 2.6.1, and the feeding driving chain 2.6.4 brings the feeding loading tray 2.6.6 along the feeding guide rail 2.6.5, and can realize horizontal movement under the guidance of the feeding guide wheel group 2.6.7.

[0034] The feeding mechanism 2.6 is lifted to a preset height with the material, the clamping plate 2.7 blocks the material, and cooperates with the three clamping cylinders 2.11 to position the material from three directions respectively. The feeding loading tray 2.6.6 of the feeding mechanism 2.6 moves back, and the material falls on the tray above the tray rotating mechanism (the tray is placed on the upper bottom plate 5.5). After the lifting mechanism is lifted to the corresponding position, the feeding loading tray 2.6.6 of the feeding mechanism 2.6 moves back to the initial position, and the lifting mechanism is lowered to the receiving position, and then the next layer of material is received, and the cycle is repeated.

[0035] In order to ensure that the angle of each layer of palletizing is different and to ensure the stability of palletizing, the pallet rotating mechanism 5 rotates the pallet 90 degrees after each layer of material is discharged, and then places the next layer of materials. When rotation is required, the rotary lifting cylinder 5.2 lifts the rotary driver 5.4 along the first linear guide rail 5.3, and the pallet falls on the upper bottom plate of the rotary driver. The rotary driver 5.4 rotates 90 degrees at the request of the control box, and then the rotary lifting cylinder shrinks, the rotary driver descends, and the pallet falls on the finished product conveying mechanism (existing technology) to stack the next layer of materials, and so on.

[0036] The empty pallet is transported to the middle of the pallet warehouse by the pallet infeed conveyor 9.3, the lifting cylinder 9.2 lifts the pallet, the locking cylinder 9.5 locks the pallet, the lifting cylinder descends, and the new empty pallet can be transported to the center and lifted again, and the cycle continues. If the pallet is needed in the palletizing part, the lifting cylinder 9.2 rises, the locking cylinder 9.5 is unlocked, and the lifting mechanism descends the pallet to a certain position.

[0037] During the palletizing process, a layer of partition can be added between the two pallets. When the lifting mechanism 2 is lowered to the material receiving position, the interlayer placing mechanism 7 moves to the top of the interlayer warehouse 7.5, and the lifting cylinder 7.3 brings the vacuum suction nozzle 7.4 down to the lowest position. At this time, in the interlayer warehouse 7.5, the lifting mechanism 7.5.2 rises to raise the partition to the highest position, and the vacuum suction nozzle 7.4 sucks up the partition. At this time, the lifting mechanism 2 starts to rise to the material discharging position, the translation mechanism 7.2 moves to the top of the pallet, and the lifting mechanism 7.3 brings the partition sucked by the vacuum suction nozzle 7.4 down to the lowest position. The vacuum suction nozzle 7.4 is disconnected to put down the partition, and then the lifting mechanism 7.3 rises to the highest position with the vacuum suction nozzle 7.4, and the translation mechanism 7.2 moves to the initial position, and so on, adding partitions to each layer of material.
