  • Patent number: 11046543
    Abstract: A conveyance device includes: a conveyance mechanism configured to unwind and convey a web from a web roll; a brake configured to brake rotation of the web roll; a controller configured to perform control of gradually reducing a torque of the brake and then turning off the brake in an operation of turning off the brake in a state where conveyance of the web by the conveyance mechanism is stopped and the brake is on with a tension applied to the web between the web roll and the conveyance mechanism.

  • Publication number: 20200262670
    Abstract: A web conveying device configured to convey a web and rewind the web into a roll includes: a moving roller arranged between a send-in port for the web and a rewinding roll which is the web rolled, the moving roller configured to be movable in an up-down direction to apply tension to the web or release the tension; and a controller configured to perform control of moving the moving roller to an upper limit position in the up-down direction in an operation of stopping conveyance of the web.

  • Publication number: 20190100399
    Abstract: A conveying apparatus includes: a conveyor including a brake to apply brakes to a web, the conveyor configured to convey the web while giving tension to the web by applying brakes to the web using torque of the brake; and a controller configured to control the conveyor. The controller performs at least one of a first control or a second control. The first control includes determining a first torque of the brake during acceleration of the web to be a value depending on a first inertial load at the conveyor during the acceleration of the web. The second control includes determining a second torque of the brake during deceleration of the web to be a value depending on a second inertial load at the conveyor during the deceleration of the web.

  • Publication number: 20190100400
    Abstract: A conveying apparatus includes: a conveyor configured to convey a web while unwinding the web from a web roll; a brake configured to apply brakes to rotation of the web roll; and a controller configured to perform control to unwind the web from the web roll and convey the web with the conveyor while giving tension to the web by applying brakes to the rotation of the web roll using torque of the brake. The controller is configured to determine the torque of the brake during deceleration of the web to be a value depending on an inertial load of the web roll.

  • Publication number: 20120260606
    Abstract: When the width of an envelope has sufficient margin for the width of a paper sheet, the aligning operation is skipped to improve productivity. As shown in FIG. 2, in an aligning apparatus 1 including an aligning unit 4 that aligns both side edges of the conveyed paper sheets, a difference value and a predetermined threshold value for use in an aligning operation execution determination are compared. The difference value is calculated by subtracting width dimension obtained from sheet size information of the paper sheet to be aligned from width dimension obtained from envelope size information of the envelope to enclose the paper sheet. The controller 7 controls not to execute the aligning operation if the difference value exceeds the predetermined threshold value.
