Opening device for outer package of containers and opening method thereof

Abstract

The invention discloses an opening device for an outer package of containers and belongs to the technical field of pharmaceutical production devices. The opening device for the outer package of the containers comprises a film cutting device and a film overturning device, wherein the film cutting device is used for cutting packaging film on three side surrounding faces of a bottle packaging material and enabling top film and bottom film of the packaging film to keep connection only at one connection edge, and the film overturning device is used for clamping the side, opposite to the connectionedge, of the top film and enabling the top film to be overturned upwards around the connection edge to be opened. The opening device for the outer package of the containers reduces the action times ofan execution mechanism and significantly improves the work efficiency of a bale breaker. The opening device for the outer package of the containers has the advantages of being simple in structure, high in work efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical production equipment, and in particular relates to an opening device for container outer packaging and an opening method thereof. Background technique [0002] Existing packaging for oral liquid bottles, ampoules, vials, etc., one of which is an all-plastic film bottle packaging material, which is wrapped with a heat-shrinkable film on the outside of the container bottle such as a medicine bottle. Before entering the bottle mesh belt, the heat shrinkable film needs to be removed. At present, most of the industry uses manual removal of packaging film and manual collection of waste, which is labor-intensive, boring and tasteless, prone to human factors such as bottle drop and bottle fall, and has a low degree of automation. [0003] At present, the rare automatic unpacking scheme adopts the method of cutting plastic film around the packaging material of the bottle, which has the following di...

AI Technical Summary

Problems solved by technology

[0004] First, the cutting route is relatively long, resulting in low film cutting efficiency and reduced unpacking efficiency;

[0005] Second, the plastic film is cut into at least two parts that are separated from each other, and each part is attached to the bottle packaging material. Different actuators are required to process the separated plastic films, resulting in a complex structure of the whole machine;

[0006] Third, it is necessary to separate the bottle and the plastic film at least twice, resulting in low work efficiency
