Abstract

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.

Dependent claims

A film roll supply device configured to supply a film roll to a bag making and packaging machine, the film roll supply device comprising:

a holding section that is configured to be located at least temporarily adjacent to a supporting shaft to support the film roll in the bag making and packaging machine, and that is configured to hold a first film roll serving as the film roll supplied to the bag making and packaging machine;
a driving unit configured to move the holding section in an up-down direction;
and
a control unit configured to control 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 a height of a center of the supporting shaft of the bag making and packaging machine;
and
a first measuring unit configured to measure a diameter of the first film roll,
wherein the control unit is configured to control the action of the driving unit based on a measurement result from the first measuring unit to move the holding section to a position where the height position of the center of the first film roll held by the holding section is aligned with the height of the center of the supporting shaft of the bag making and packaging machine.
