  • Publication number: 20240083705
    Abstract: A film-roll supply device improves replacement of a film roll in a bag-making and packaging machine. A film roll replacement device supplies a first film roll to a bag-making and packaging machine. The film roll replacement device is provided with a holding section and a first driving unit. The holding section receives the first film roll to be supplied to the bag-making and packaging machine. The first driving unit changes an orientation of the holding section between a first orientation used when receiving the first film roll and a second orientation used when supplying the first film roll to the bag-making and packaging machine.

  • Publication number: 20240017948
    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.

  • Patent number: 11649083
    Abstract: A bag-making and packaging apparatus includes a bag-making and packaging unit, a film feeding unit, a splicing device, and a control unit. The control unit allows a bag-making operation to continue by utilizing an auto-feeding function that feeds to the bag-making and packaging unit a film F spliced by the splicing device to take the place of a film F currently being fed to the bag-making and packaging unit. When the control unit judges that at least one of the film feeding unit and the splicing device is malfunctioning in a case where the control unit is utilizing the auto-feeding function, the control unit stops the auto-feeding function and executes a non-auto-feeding mode. The non-auto-feeding mode allows the bag-making operation to be continued by the bag-making and packaging unit and a film roll holding unit that is operable among plural film roll holding units.

  • Patent number: 11046468
    Abstract: 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 a film conveyance mechanism that conveys a first film so that a trailing end portion of the first film heads toward a film splicing position for splicing to a leading end portion of a second film, a first sensor detecting a mark on the first film, a second sensor detecting the mark at downstream, and a controller for the film conveyance mechanism. The controller judges, based on detection of the second sensor, that the trailing end portion of the first film has reached the splicing position and stops conveyance of the first film. The controller controls the conveyance mechanism so that the conveyance speed of the first film before the detection of the mark by the first sensor is faster than the speed after the detection.
