Description

Technical Field

[0001] The present invention relates to the technical field of palletizing equipment, and particularly to a high-level palletizer transportation line. Background Art

[0002] The high-level palletizer transportation line is used to realize the automatic palletizing and transportation of goods. Generally, it can pick up goods from the conveyor line and palletize them according to specified rules. At the same time, it can automatically transport the palletized goods to a specified area to complete the automated operations of palletizing and logistics.

[0003] When palletizing goods at a high level, it is necessary to stack the goods from low to high. Currently, there are two common palletizing methods: suction cup adsorption palletizing and goods pushing palletizing. Among them, suction cup adsorption palletizing relies on the adsorption force of the suction cup to pick up and place goods for palletizing, and can only effectively adsorb regular goods with an adsorbable surface, so its use has certain limitations, and it is easy to damage the goods when the suction cup releases the goods for palletizing; while goods pushing palletizing uses the method of pushing up and down the pallet in cooperation with pushing the goods. When palletizing bagged goods with a certain weight, when there is already a layer of goods at the bottom of the pallet, the upper layer of goods is horizontally pushed above the first layer of goods for palletizing. When performing horizontal pushing, the friction between the goods is relatively large, and it is extremely easy to cause the goods bags to burst. Therefore, there is an urgent need for a high-level palletizing transportation device to solve such problems. Summary of the Invention

[0051] Among them, the first telescopic column 12, the second telescopic column 35, the third telescopic column 38, and the fourth telescopic column 41 can respectively adopt air cylinders.

[0052] The working process of the high-level palletizer transportation line provided in this embodiment is as follows:

[0053] For the convenience of description, hereinafter, the palletizing installation groove plate, the palletizing push plate, and the multiple palletizing push bars of the lower palletizing assembly are respectively referred to as the lower palletizing installation groove plate 46, the lower palletizing push plate 47, and the multiple lower palletizing push bars 48, and the palletizing installation groove plate, the palletizing push plate, and the multiple palletizing push bars of the upper palletizing assembly are respectively referred to as the upper palletizing installation groove plate 49, the upper palletizing push plate 50, and the multiple upper palletizing push bars 51.

[0054] Place the goods on the goods lifting conveyor belt 8 and rely on the goods lifting conveyor belt 8 to convey them upward to the turning conveyor belt 9. Determine whether it is necessary to adjust the angle of the goods according to the actual goods stacking situation. When no goods angle adjustment is required, the goods are directly input onto the roller conveyor section 10 through the turning conveyor belt 9; when goods angle adjustment is required, rely on the conveying and turning mechanism 11 to rotate the goods on the turning conveyor belt 9 within the horizontal plane, usually by rotating 90 degrees, and then input them onto the roller conveyor section 10. On the roller conveyor section 10, rely on multiple rotating conveyor rollers 20 to convey the goods. When the goods reach above the multiple transfer fork bars 22, the first lifting drive mechanism operates to drive the transfer mounting plate 21 and the multiple transfer fork bars 22 thereon to rise, lift the goods on the conveyor rollers 20 upward, and transfer the goods from the conveyor rollers 20 to the multiple transfer fork bars 22. At this time, the height positions of the multiple lower stacking push bars 48 of the lower stacking assembly are adjusted to be flush with the lifted transfer fork bars 22 and are connected to the transfer fork bars 22 in the front-rear direction. Then, the first horizontal cylinder on the multiple transfer fork bars 22 operates to drive the push bar 24 to move, push the goods forward to the multiple lower stacking push bars 48. When the goods are completely transferred to the multiple lower stacking push bars 48, the shaping mechanism 4 operates, and the second telescopic column 35 drives the movable shaping plate 34 to move towards the fixed shaping plate 33, so as to make all the goods on the lower stacking push bars 48 lean towards the fixed shaping plate 33 side, realizing the alignment of the goods in the first layer of stacking. After the first layer of stacking is completed, when stacking the second layer, the entire lower stacking assembly moves downward by the height of a single layer of goods, adjusts the front-rear position and height position of the upper stacking assembly, so that the multiple upper stacking push bars 51 of the upper stacking assembly replace the previous multiple lower stacking push bars 48 to reach the goods receiving position, and use the multiple upper stacking push bars 51 of the upper stacking assembly as the support for the second layer of goods. In the same way, transfer the goods on the transfer fork bars 22 to the multiple upper stacking push bars 51 and rely on the shaping mechanism 4 to shape the second layer of goods, that is, complete the alignment of the second layer of goods. Then, horizontally withdraw the multiple upper stacking push bars 51. Due to the blocking of the multiple stop bars 31, the goods will not move together with the movement of the upper stacking push bars 51. As the multiple upper stacking push bars 51 are gradually withdrawn, the second layer of stacked goods leaves the support of the upper stacking push bars 51 and gently falls onto the first layer of stacked goods below, relying on the top of the first layer of stacked goods as the support surface for the second layer of stacked goods. At this time, the stacking of the second layer of goods is completed. Repeat the above steps to stack the third layer of goods until multiple layers of stacking are completed. When the first layer of stacked goods reaches the lowest position, the multiple lower stacking push bars 48 are inserted into the multiple grooves on the pallet 7, and the pallet 7 supports the stacked goods. Then, horizontally withdraw the multiple lower stacking push bars 48 and reset them.
