Background

Can lids are commonly used for covering canned products, and manufacturers for producing canned products generally do not independently produce and process the can lids, and the production and processing of the can lids are specially responsible for the can lid manufacturers.

As shown in fig. 1 to 2, when transporting can lids a produced by a can lid manufacturer, a plurality of can lids a are packed in a paper bag as a group, and are packaged into can lid strips B, and the can lid strips B are stacked layer by layer on a can lid strip stacking pallet C to form a can lid strip stack D, and then are transported in bulk.

In order to prevent the stack D of can lids from falling apart due to vibration during transportation, the can lid B of each layer is usually integrally wound with the wrapping tape F, and the end of the wrapping tape F is pressed under a part of the can lid B. Therefore, when a can lid stack D is received by a can lid manufacturer (i.e., a can lid user) that produces a canned product, not only the drum conveyor is required to convey the can lid stack D, but also the winding tape F needs to be sequentially and repeatedly unwound and the can lid B of the same layer needs to be removed.

At present, the winding belt F of each layer needs manual operation, after the winding belt F is unwound, the tank cover strip B of the uppermost layer is lifted to the position flush with the tank cover strip conveying belt by a lifting mechanism, and then the tank cover strip B of the layer is pushed to the tank cover strip conveying belt by a pushing mechanism.

Observation shows that manual operation is needed for unwinding the winding belt F of each layer, so that the unstacking efficiency of the can cover strip stack is greatly reduced; in addition, in the pushing process of the pushing mechanism, the cylindrical can cover strip B is easy to roll randomly and move, so that the conveying belt of the can cover strip cannot convey normally, and the failure rate in the unstacking process is high.
