Description

Technical Field

[0001] This utility model relates to the technical field of beverage can production equipment, and more specifically to an automatic unloading device for lid strips. Background Technology

[0002] Depalletizers are machines commonly used in workshops to unload products, particularly in aluminum can manufacturing plants. The metal lids of aluminum cans are stacked into complete lid strips, which are then stacked into complete lid strip stacks. These stacks are typically unpacked using a depalletizer, transferring the individual lid strips to the next process via a conveyor belt. However, a common problem encountered during the actual unpacking process is the use of buffer plates between layers of lid strips to prevent deformation from hard impacts during transport, as well as the bottom base plate. Existing depalletizers typically use suction cup assemblies for unpacking, requiring workers to remove the buffer plates and base plates after each layer. This significantly increases the workload for workers, negatively impacts unpacking efficiency, and poses a safety hazard for workers standing next to the depalletizer. This problem urgently needs to be addressed. In response to this, the inventor proposes an automatic unstacking device for cover strips. By improving the unstacking components, the unstacking components can achieve normal unstacking and can classify and place the buffer plates and base plates. The entire process can be completed automatically without manual intervention, which is beneficial to improving the production efficiency of enterprises, reducing the labor intensity of workers, and improving the production safety of enterprises.

[0003] To achieve rapid unpalletizing of empty aluminum cans and improve production efficiency and automation, Chinese Patent (Authorization Announcement No.: CN204021952U) discloses an automatic unpalletizing machine for empty aluminum cans. This utility model includes a conveyor platform on which stacks of aluminum cans are sequentially placed. The conveyor platform is driven forward by a drive device, and a unpalletizing machine housing is provided in the forward direction of the conveyor platform to accommodate the stacks. A lifting device is provided inside the unpalletizing machine housing to raise and lower the stacks. A scraper device is provided at the top of the unpalletizing machine housing to push one layer of cans onto the conveyor belt. This automatic unpalletizing machine for empty aluminum cans enables rapid transportation and unpalletizing, improves work efficiency, ensures production capacity, reduces labor costs, and has a reasonable structural design, making it practical.

[0004] The solution still has some shortcomings in application. Since cans or lids are stacked, buffer plates are placed on the upper and lower layers of each material during stacking, and a base plate is placed at the bottom for easy transportation. Therefore, in addition to unloading the material, the buffer plates and base plates need to be disassembled and sorted for easy subsequent storage. Otherwise, manual handling is time-consuming, labor-intensive, and poses safety hazards. Therefore, the structure of the lid unloading device needs to be improved to overcome the above-mentioned problems, so that the unloading device can also disassemble and sort the buffer plates and base plates for easy subsequent storage, improve the automation level of unloading, and improve production efficiency.
