Claims

[Scope of Claim for Utility Model Registration] (1) Packaging in which the packaged product is pushed up from below a film held under tension by a packaging station, and the peripheral edge of the film is folded into the bottom side of the packaged product using a folding member. In the apparatus, the film transport mechanism for transporting the film to the packaging station includes a pair of transport units that respectively grip both side edges of the film in the width direction and transport the film to the packaging station, and at least one of the pair of transport units. 1. A packaging device comprising: a spacing adjustment mechanism that applies a required tension to the film by moving the film in the width direction of the film to adjust the spacing between both transport units. (2) A packaging device that pushes up a packaged product from below a film held under tension on a packaging station, and folds the peripheral edge of the film into the bottom side of the packaged product using a folding member. A film transport mechanism that transports the film to the packaging station includes a pair of transport units that respectively pinch both edges of the film in the width direction and transport the film to the packaging station, and from the time when the pair of transport units starts transporting the film, the film is transported by the folding member. and an interval adjustment mechanism that adjusts the interval between the pair of conveyance units by moving at least one of the pair of conveyance units in the width direction of the film until the start of folding. The interval adjustment mechanism is operated in synchronization with the operation of the folding member so that the tension of the film is maintained at an optimum level when the side edge of the sandwiched film is folded into the bottom side of the packaged product by the folding member. A packaging device characterized in that it is equipped with a control means for controlling.
