METHOD FOR REMOVING INJECTION-MOLDED ITEMS

摘要

The invention relates to a method for removing injection-molded items from an injection-molding machine by means of a robot. The injection-molding machine and the robot are each provided with a separate drive, and each drive can be acted on by a separate open- and closed-loop control unit that can be programmed separately. The injection-molding machine is equipped with at least one signaling device for detecting a position of the mold. The signal (S1, S2, S3) of the signaling device is applied to the open- and closed-loop control unit of the robot, said open- and closed-loop control unit containing a computing element. The motion sequence (b) of the robot specified by means of the open- and closed-loop control unit is recalculated after each removal cycle according to the edge, preferably the negative edge, of said signal (S1). The robot is moved from the start position of the robot for the next removal cycle by means of a timer, which is based on the recalculated start time (st).
