Benefits of technology

[0008]The present invention is directed to a method and apparatus for debanding a compressible bundle. In a preferred embodiment of the invention, an apparatus is configured to cut a band that surrounds a compressible bundle of polyethylene bags by driving one or more indenters into an outer surface of the compressible bundle, in a manner that depresses the surface of the compressible bundle to form a trough that crosses underneath a portion of the band. The apparatus then moves a cutting knife along a longitudinal direction of the trough to cut the band. As the cutting knife is being moved, it extends at least partially into the trough without contacting the surface of the bundle. As a result, cutting of the band is accomplished without risking damage to the bundle from the cutting operation.

Problems solved by technology

Each of the manual processes used to process the bundles is inherently inefficient.
However, automated processing can introduce a risk of damaging some of the bags, for example, during the debanding step.

Embodiment Construction

[0029]The present invention is directed to a method and apparatus for debanding a compressible bundle, and in particular, for debanding a compressible bundle of bags (for example, polyethylene bags) which are banded (for example, with paper bands, rubber bands, polyethylene bands, or bands comprising any of a variety of other conventional band materials).

[0030]In a preferred embodiment of the invention, bundles of bags are arranged in a single-file grouping along a moving direction of a debanding conveyor line. Each bundle of bags is secured by a band that circumferentially surrounds a portion of the bundle. The bundles may be manually provided to the conveyor line, or may be provided to the debanding conveyor line by an intake system including a hopper that receives and sorts the bundles of bags before depositing the bundles either onto the debanding conveyor line, or onto accumulator conveyor line that is configured to accumulate and transfer the bundles to the debanding conveyor ...

Abstract

A method and apparatus for debanding a compressible bundle. The apparatus includes an End of Arm Tooling (EAT) component which is moved vertically downward over the bundle to a position where holding arms of the EAT component are manipulated to pick up and hold the bundle. At this position, one or more indenters of the EAT component are pressed into an upper surface of the bundle form a trough in the bundle that crosses under a band which surrounds the bundle. A cutting knife assembly of the EAT component is actuated to slide linearly along a longitudinal direction of the trough to cut the band without contacting the surface of the bundle, thereby enabling the band to drop away from the bundle. As a result, the bundle can be debanded without damaging the bags.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit under 35 U.S.C. §119(e) of U.S. Patent Application No. 61 / 183,249, entitled “Method and Apparatus for Debanding a Compressible Bundle,” filed Jun. 2, 2009, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]This invention relates to a method and apparatus for removing a packaging band from a compressible bundle, and in particular, to a method and apparatus for cutting and removing the packaging band surrounding a bundle of bags, without damaging any of the bags.BACKGROUND OF THE INVENTION[0003]It is generally known in the manufacturing arts to package certain kinds of articles by stacking or rolling the articles together in a bundle, and securing the bundle by applying a band or other type of wrapper to an exterior surface of the bundle. For example, it is known in the container industry to prepare bundles of bags in bag rolls which are secured by paper, elastic and oth...
