Claim Text:
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.
