A film roll replacement device supplies a film roll to a bag making and packaging machine. The film roll replacement device includes a holding section, a driving unit, and a controller. The holding section is at least temporarily located adjacent to a supporting shaft to support the film roll in the bag making and packaging machine, and the holding section holds a first film roll supplied to the bag making and packaging machine. The driving unit moves the holding section in an up-down direction. The controller controls an action of the driving unit to move the holding section to a position where a height position of a center of the first film roll held by the holding section is aligned with the height of a center of the supporting shaft of the bag making and packaging machine.

Film roll supply device

A bag-making and packaging machine includes a bag-making and packaging section and a film supply section. The film supply section includes a film conveyance section that conveys a starting end portion of a replacement film roll supported by a film roll support portion to a bonding portion. The film conveyance section includes a clamping portion that holds a tape adhering to the starting end portion of the replacement film roll, and a pulling mechanism that pulls a second film held by the clamping portion from the replacement film roll. When the replacement film roll is mounted, the film roll support portion rotates the replacement film roll, and the clamping portion holds the tape of the replacement film roll rotated by the film roll support portion.

Bag-making and packaging machine

A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has holding mechanisms each having a shaft that holds a film roll, a holding mechanism support frame supporting the holding mechanisms, a moving mechanism that rotates the holding mechanism support frame to move each holding mechanism between a film roll setting position and a film supply position, a splicing mechanism splicing a trailing end portion of the film of the roll of one of the holding mechanisms and a leading end portion of the film of the roll of another one of the holding mechanisms, and a film drawing mechanism that rotates the shafts of the holding mechanisms to draw the film independently from the film rolls attached to the shafts of the holding mechanisms and changes the drawing speed of the film during bag-making and packaging.
