Method for removing injection-molded items

摘要

Method for removing injection-molded items from an injection-molding machine via a robot and device for performing method. The injection-molding machine and the robot each having a separate drive, and each drive is acted on by a separate open- and closed-loop control unit that is separately programmable. At least the open- and closed-loop control unit of the robot contains a computing element, and the injection-molding machine is equipped with at least one signaling device for detecting a position of the mold. The method includes applying a signal of the signaling device to the open- and closed-loop control unit of the robot, recalculating a motion sequence of the robot based of the open- and closed-loop control unit after each removal cycle, and for each next removal cycle, moving the robot from a start position by a timer at a recalculated start time.

1. A method for removing injection-molded items from a mold of an injection-molding machine via a robot, the injection-molding machine and the robot each having a separate drive, and each drive being acted on by a separate open- and closed-loop control unit that is separately programmable, at least the open- and closed-loop control unit of the robot contains a computing element, and the injection-molding machine being equipped with at least one signaling device for signaling a detected position of the mold, the method comprising:
applying a signal of the signaling device to the open- and closed-loop control unit of the robot; recalculating a motion sequence of the robot based on the open- and closed-loop control unit of the robot after each removal cycle; and for each next removal cycle, moving the robot from a start position at a recalculated start time determined by a timer, wherein the open- and closed-loop control unit of the robot further comprises a time-measuring element, and the method further comprises measuring a time period that is a time from a negative edge of the signal for detecting the mold-closed position up to a positive edge of the signal for detecting the mold-open position with the time-measuring element; and storing the measured time period in the open- and closed-loop control unit of the robot.
