PACKAGING BAG SUPPORTING DEVICE

摘要

PROBLEM TO BE SOLVED: To put a commodity without any trouble by providing a supporting mechanism to maintain an opening part formed in a packaging bag in an opened condition by arranging an adhesive piece to implement the adhesive effect to the opening part aside a placement part to maintain the opening part in an opened posture so as not to be broken down. SOLUTION: A packaging bag maintaining part comprising a chain 10(a) to be synchronously driven with a roller conveyor 1 is arranged on right and left sides of the roller conveyor 1 to convey corrugated fiberboard boxes 6 at a specified speed. Adhesive sheets 9 are arranged at specified intervals on the chain 10(a) so as to be matched with the conveying interval of the corrugated fiberboard boxes 6. The adhesive sheets comprising a modified polyurethane rubber layer implement the adhesive effect to an outer surface of an opening part 7A of a packaging bag 7 projecting upward from the corrugated fiberboard boxes 6. The adhesive/peeling effect of the adhesive sheets 9 to/from the opening part 7A is repeatable by forming the packaging bag 7 of a plastic film of ethylene or the like.
