Description

  The present invention relates to a binding release device that can release, for example, a bundled advertisement that is bound by a binding element.

  Conventionally, insert advertisements that are inserted into newspapers and delivered to subscribers are bundled with a binding band made of polypropylene or the like at a sorting distribution center that sorts the insert advertisements to each newspaper store until the sorting date. Stored in the same state.

  When performing the sorting operation, first, a hand is formed between the binding band that tightly binds the folded advertisement and the folded advertisement to release the bundle, and a cutter is inserted into the gap. After cutting a part of the binding band, fold the cut binding band and remove it from the bottom of the advertisement. Then, the extracted binding band is discharged into a waste bag.

Folded advertisements that have been unbound in this way are sorted into the number or number of copies of each newspaper store based on the sorting information on the label that indicates which newspaper store they are intended for, and are then bound again by route. Forwarded to the delivery department. (For example, Patent Document 1)
Japanese Patent No. 3680079

  However, the unfolding advertisement binding release work is physically harsh for the operator, and usually the folding advertisement is often bundled by a plurality of binding bands. Must be repeated multiple times.
