Device and method for introducing opening into partial region of film wrap

Abstract

The invention relates to a device for introducing an opening into a partial region of a film wrap of a stack of goods, preferably arranged on a pallet, the film wrap being designed as a film cover which is laid on the stack of goods or as a film strip which at least partially surrounds the stack of goods, the device comprises a piercing element with a piercing region and at least one operating arm on which the piercing element is rotatably fixed about an axis of rotation. In order to provide a device by means of which an opening can be introduced into a weld seam, into a region of a backing film surrounding the stack of goods, into a collar extension or into a collar contraction of the film wrap, the piercing element should have a first partial region and a second partial region, the first partial region being rotatably mounted on the actuating arm, and the second partial region being rotatably mounted on the actuating arm. The second sub-region has a piercing region, and wherein the second sub-region can be pivoted in at least one direction relative to the first sub-region from the original position against the restoring force.

Description

technical field [0001] The invention relates to a device for introducing an opening into a subregion of a film wrapping (Folienumhuellung) of a stack of goods, preferably arranged on a pallet, wherein the film wrapping comprises a film cover that is covered with the stack of goods and necessarily when including a backsheet film arranged under the pile of goods or a film wrapping comprising a film band (Folienbanderole) at least partially surrounding the pile of goods and optionally including a backsheet film arranged under the pile of goods, a) in which the film wrapping is welded to the base film lying below the load, forming a weld seam that runs horizontally around the load, and Either the opening is introduced into the weld, However, either openings are introduced into the region of the backsheet film surrounding the stack of goods (preferably adjacent to the weld seam), or b) in which the film wrapping has a collar-like constriction (Kragenschrumpf) that runs hori...

Problems solved by technology

Otherwise problems may arise in downstream processes (e.g. in the case of transport, in the case of depalletizing and in the case of storage (e.g. in high-bay warehouses)) if the remainder of the film cover is not removed
