  • Publication number: 20220017322
    Abstract: The aligning device receives a sheet conveyed in a sheet conveyance direction in a stackable manner and aligns a position of the sheet in the sheet conveyance direction. The moving mechanism moves the sheet aligned by the aligning device in the sheet conveyance direction together with the aligning device. The controller selectively executes a first mode in which first post-processing is performed on the sheet and then second post-processing is performed on the sheet and a second mode in which the second post-processing is performed on the sheet without performing the first post-processing on the sheet. The controller, in response to a selection of the first mode or the second mode, causes the moving mechanism to adjust a position of the aligning device in the sheet conveyance direction before the aligning device receives the sheet as a target of the first post-processing or the second post-processing, respectively.

  • Patent number: 9606493
    Abstract: A punching device includes: a punching member opens a punch hole on a sheet material on a die plate by penetrating a die hole provided to the die plate; a discharging member discharges static electricity charged on a punching chip generated by opening of the punch hole when the punching chip is guided to fall on the discharging member arranged on a lower side of the die hole and brought into contact with the discharging member; and a pressing member that presses the punching chip on the discharging member against the discharging member.

  • Patent number: 4201937
    Abstract: Control apparatus is provided to control a programmable manipulator having a manipulator arm movable in a plurality of axes to perform a predetermined pattern of work operations in a replay cycle with respect to a movable workpiece while the workpiece is moving or is stationary at a point along a predetermined workpiece path. In replay, the control apparatus generates interpolation control signals from stored data in accordance with the workpiece position. The stored data includes two or more series of signals representing manipulator arm positions to accomplish the predetermined pattern of work operations with respect to the workpiece at two or more respective positions of the workpiece.During replay, data is read out from the two series of signals that are associated with workpiece positions on either side of the present workpiece position.

  • Patent number: 3943343
    Abstract: A program control system is disclosed wherein the coordinates of a plurality of specified points of a prescribed path in the space to be traced by a manipulator assembly which are spaced apart from each other by a line segment of the same unit length are stored in a storage device in a teaching mode, and one set of coordinates of the adjacent specified points are simultaneously and sequentially read out from the storage device in a repeat mode so that the position command signals or coordinates of a plurality of interpolation points between the adjacent specified points are obtained by linear interpolation and are sequentially compared, at a predetermined time interval, with the actual or present positions of the manipulator assembly. The manipulator assembly is displaced at a velocity corresponding to the difference between the position command signal and the actual or present position signal so that the difference may become zero.
