  • Patent number: 11951704
    Abstract: The press device is a press device configured to press a workpiece, and includes a slide, a bolster, a servomotor, and a control section. The slide is movable. The bolster is placed to face the slide. The servomotor drives the slide. The control section is configured to be able to execute selectively either the productivity priority mode of setting a limit value slower than the maximum press speed of the press device to the press speed when performing a pendulum motion or a reverse motion, or the moldability priority mode of setting a stop time to the servomotor without setting the limit value.
    Type: Grant

  • Publication number: 20200180252
    Abstract: A press system capable of achieving a reduced number of man-hours required for generation of a motion is provided. A controller automatically generates a press motion based at least on a feed-allowable height, a touch position, and a work end position, automatically generates a feeder motion based at least on a feed-allowable height and a feed length, and automatically generates a synthesized motion by synthesizing the press motion and the feeder motion.

  • Publication number: 20200171773
    Abstract: A controller controls a slide to stop when the slide moves upward and downward as a result of operation of a two-hand push button panel to reach a target position (for example, a feed-allowable height, a touch position, a work end position, and a jump prevention height) even though an operation signal from the two-hand push button panel is being input to the controller.

  • Publication number: 20200171561
    Abstract: A press system capable of achieving improvement in production rate is provided. A controller has a slide driven upward and downward based on a prescribed press motion. A position of the slide where a workpiece can be transported without interfering with an upper die is defined as a feed-allowable height. A stand-by height is higher than the feed-allowable height and located at a highest position in the press motion. The controller also has the work transported while the slide is moving between the feed-allowable height and the stand-by height.

  • Patent number: 10065324
    Abstract: A conveying apparatus conveys an article between a wait position and a processing position. The conveying apparatus includes a plurality of arms that sandwiches the article between leading ends of the arms located on opposite sides of the article and that is provided to enable base ends of the arms to turn so as to move the leading ends in an up-down direction, and a control apparatus that turns the arms to lift the article located at one of the wait position and the processing position and sandwiched between the arms and that moves the arms with the article kept lifted thereby to the other of the wait position and the processing position, the control apparatus turning the arms to lower and mount the article at the other of the wait position and the processing position.
