  • Patent number: 10793384
    Abstract: A roll conveyance device includes a transportation device including a roll holding shaft extending in a predetermined direction from a distal section of an arm to hold a roll such that the roll holding shaft is inserted into a core member of the roll; and a mounting section within a moving range of the roll holding shaft, the mounting section allowing the roll to be mounted in a state in which both axial ends of the core member of roll are open. The transportation device is configured to mount the roll on the mounting section, the roll holding shaft is to be pulled out from the core member of the roll mounted on the mounting section to a first side of an axial direction of the core member, and the roll holding shaft is to be inserted into the core member from a second side of the axial direction.

  • Patent number: 10472196
    Abstract: A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an end section conveying apparatus which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives a standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.

  • Publication number: 20190337747
    Abstract: The present invention includes a transportation device including a transportation-side holder that holds a roll. A roll mounting section, a sheet supply device including a supporter that holds the roll in a state where the sheet is continuously feedable, and an intermediate processing device that performs processing set in advance on the roll are disposed within a moving range of the transportation-side holder. A controller controls the transportation device such that the transportation-side holder holds the roll on the roll mounting section, and the roll held by the transportation-side holder is conveyed to the supporter of the sheet supply device through the intermediate processing device.

  • Patent number: 10329111
    Abstract: A joining unit includes: a suction holding member having a suction surface configured to suction an end section of a sheet; a moving mechanism configured to move the suction surface toward an intermediate section of a sheet of a delivery-side original material roll along a path set in advance so that tension is applied to the sheet; and a regulating mechanism that is configured to switch between a regulated state in which a movement of the end section of the sheet with respect to the suction holding member due to the tension is regulated and an allowable state in which the movement of the end section of the sheet with respect to the suction holding member is allowed. The controller switches the regulating mechanism to the regulated state during the movement of the suction surface toward the intermediate section of the sheet of the delivery-side original material roll.

  • Patent number: 10233045
    Abstract: A sheet delivery system includes: a joining unit configured to join, to an intermediate section of a sheet being delivered from a delivery-side original material roll, an end section of a sheet of a standby-side original material roll; and an operation robot configured to retrieve the end section of the sheet from the standby-side original material roll and convey the end section of the sheet to the joining unit. The sheet delivery system is configured to set, in advance, a sheet retrieval position at which the sheet is retrieved from each of the original material rolls, for each of the original material rolls. The operation robot is configured to convey the end section of the sheet from each of the sheet retrieval positions to the joining unit.

  • Publication number: 20170137248
    Abstract: A sheet delivery system includes: a joining unit which joins, to an intermediate section of a sheet being delivered from a delivery-side original material roll, an end section of a sheet W of a standby-side original material roll; and an operation robot which retrieves the end section of the sheet from the standby-side original material roll and which conveys the end section of the sheet to the joining unit. The sheet delivery system sets, in advance, a sheet retrieval position at which the sheet is retrieved from each of the original material rolls, for each of the original material rolls. The operation robot is configured to convey the end section of the sheet from each of the sheet retrieval positions to the joining unit.
