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.
