Abstract

In a packaging apparatus, when replacing a preceding single-faced corrugated fiberboard (wrapping material) with a subsequent single-faced corrugated fiberboard, a draw-out roller is operated such that the preceding single-faced corrugated fiberboard is drawn out to its trailing end. At this time, a reserve roller, around which the single-faced corrugated fiberboard is trained, is moved such that the single-faced corrugated fiberboard, which has been drawn out, is accumulated thereat. Then, the trailing end of the preceding single-faced corrugated fiberboard and a leading end of the subsequent single-faced corrugated fiberboard are joined together at a joining device. In this way, the preceding single-faced corrugated fiberboard can be used up until its final end, and thus there is no waste of the single-faced corrugated fiberboard.

Claims2

Dependent claims

A packaging method for drawing a packaging material out from a packaging material roll in which the packaging material is wound-up in a form of a roll, and wrapping the packaging material around side surfaces of a loaded object which is loaded on a pallet, the packaging method comprising:

detecting that a remaining length of the packaging material has become shorter than a length needed to wrap around the side surfaces of the loaded object;
after the detecting, stopping the wrapping of the packaging material around the side surfaces of the loaded object;
increasing an amount of the drawn-out packaging material trained on accumulating rollers comprising a set of fixed and reserve rollers by moving the reserve roller away from the fixed roller;
fixing the reserve roller and stopping drawing-out of the packaging material, when a trailing end of the packaging material is drawn out to a joining position at which the trailing end of the packaging material is joined together with a leading end of a subsequent packaging material;
joining together the trailing end of the packaging material and the leading end of the subsequent packaging material;
and
after the joining, starting wrapping of the packaging material onto the side surfaces of the loaded object and drawing-out of the subsequent packaging material from a packaging material roll.
