Claims

[Scope of Claim for Utility Model Registration] (1) A film in a packaging device that pushes up a packaged product from below a film held under tension by a packaging station and folds the peripheral edge of the film into the bottom side of the packaged product. The supply device includes a roll support mechanism that rotatably supports the roll of film, and a film transport mechanism that transports the film fed out from the support mechanism to the packaging station while holding both sides of the film in the width direction. . A film supplying device for a packaging apparatus, comprising: an adjusting means for automatically adjusting a film nipping position of the film transport mechanism based on a set position of a film roll set in the roll support mechanism. (2) A film feeding device for 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 for packaging, the film supply device comprising: a roll support mechanism that rotatably supports the roll; a film transport mechanism that transports the film unwound from the support mechanism to the packaging station while holding both sides of the film in the width direction; and a film transport mechanism that is set in the roll support mechanism. and adjusting means for automatically adjusting the film nipping interval of the film transport mechanism based on the roll width of the film roll. (3) A film supply device for 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, the film supply device comprising: a roll support mechanism that rotatably supports a roll; and a film transport mechanism that transports the film unwound from the support mechanism to the packaging station, wherein the roll support mechanism includes a roll bar that supports the roll; The film transport mechanism is composed of a fixed holder provided on the roll bar, and a movable holder movable on the roll bar to sandwich both ends of the roll between the fixed holder and the fixed holder. A fixed-side transport unit that grips and transports one side of the film in the width direction, and a fixed-side transport unit that also grips and transports the other side of the film in the width direction and adjusts the interval. and a movable conveyance unit which is movable to obtain the film width, and the distance between the two units in the film conveyance mechanism corresponds to the film width depending on the position of the movable holder in the roll support mechanism. What is claimed is: 1. A film feeding device for a packaging device, characterized in that it is provided with a driving means for driving a movable conveying unit so that (4) A film supply device in a packaging device, wherein the roll support mechanism rotatably supports the roll of film, and includes a roll bar that supports the roll, a fixed holder provided at one end of the roll bar, and a roll support mechanism that rotatably supports the roll of film. It is composed of a movable holder that is movably supported by the roll bar and clamps both ends of the roll between it and a fixed holder, and an elastic member that biases the movable holder in a direction toward the fixed holder, and the fixed holder A packaging device characterized in that the holder has a diameter that allows the roll of film to be inserted therethrough, and is provided with locking means that protrudes and locks one end of the roll after the roll is inserted into the holder. film feeding device.
