METHOD FOR CONTROLLING OPERATION TIME OF TAKE-OUT ROBOT

摘要

PURPOSE: An operation time control method of a take-out robot is provided to improve working efficiency, and to increase the productivity of the injection molding machine by reducing the withdrawal time of formed materials with the take-out robot. CONSTITUTION: An injection mold is opened in finishing injection-molding process, and a gripping unit is moved down and forward. A formed material is discharged and transferred by the gripping unit. The gap between fixed and moving molds is measured when opening the moving mold in finishing injection molding, and the gripping unit is moved down if the gap is over the minimum distance not to collide with the mold assembling part in moving the gripping unit between molds. The lower end height of the gripping unit is measured while the griping unit is moved back and up with gripping the formed material. The moving mold is closed in passing the lower part of the gripping unit through the upper part of the injection mold.
