Description

Technical Field

[0001] The invention relates to the technical field of depalletizers, in particular to an automatic depalletizer. Background Art

[0002] The packaging and palletizing of bagged goods have been basically automated. However, in the process of logistics transportation, it is often necessary to split the palletized bagged goods into single bags and transport them in units of bags, such as loading and shipping, and mixing ingredients in the production process.

[0003] In the logistics system of grain and oil products, after the bagged grain products are shipped out of the warehouse, the forklift is used to transport the fake bagged grain products on the pallet from the warehouse to the vicinity of the transport vehicle. The bagged grain products on the pallet are mostly stacked. During the loading process, the bagged grain products on the pallet need to be depalletized first, so that they can be rearranged and stacked when loading. Depalletizing machines are mostly used for depalletizing, but most of the existing depalletizing machines use robot arms for depalletizing. The cost of the robot arms is relatively high, and the cost of repairing them if damaged during the depalletizing process is high. In addition, the robot arms need to accurately clamp the bagged grain products and then put them on the conveyor belt to transport the bagged products to the transport vehicle. The robot arms need to perform grabbing, clamping, transferring and loosening actions, which greatly affect the depalletizing efficiency. Therefore, in order to solve such problems, we propose an automatic depalletizing machine. Summary of the invention

[0017] 2: The output shaft of the lifting motor in the present invention drives the screw rod to rotate so that the internal thread block moves up and down on the screw rod, thereby driving the third fixed plate to move up and down, so that the height of the toggle plate can be adjusted, and can be adjusted according to the stacking height of the bagged grain products stacked on the pallet. The piston rod of the second hydraulic cylinder pushes the receiving plate to move horizontally to adjust the receiving position of the receiving plate, and can be adjusted according to the stacking width of the bagged grain products stacked on the pallet, so that the bagged grain products tipped over by the toggle plate fall onto the receiving plate, and because the top of the receiving plate is an inclined surface, the bagged grain products slide onto the conveyor belt connected to the front of the receiving plate to transport the bagged grain products, which greatly improves the efficiency of destacking and transporting the bagged grain products.
