Description

Automatically removing system for wrap up package}

The present invention relates to an automatic packaging package removal system, and more particularly, to an automatic packaging package removal system for removing packaging packages of loads stacked on a pallet.

In general, after products produced in a factory are loaded on a pallet, they are wrapped with a wrap film made of polyethylene or vinyl chloride resin to protect the product from moisture or dust and to facilitate product transportation.

Wrapping of these products may be performed through a wrapping device.

In the case of a conventional wrapping device, when a wrap is wrapped in a product, sufficient tension is applied to the wrap to wrap the wrap around the product, so the wrap is not easily peeled off from the product, and watertightness and airtightness of the wrap are maintained.

Accordingly, a person manually removes the wrap from the product wrapped in the wrap by the wrapping device. In this case, problems such as reduced work efficiency and product damage in the process of removing the wrap may occur.
