Abstract: A device for removing runners from intermediate molded products includes a holding assembly for maintaining the products in a desired position, a hammer member, an assembly for vibrating the hammer member to cause repeated striking of the intermediate product so as to separate runner and product portions thereof and a control arrangement for selectively activating and deactivating the vibrating assembly. The control arrangement provides for positioning the vibrating assembly in at least one predetermined position upon deactivation thereof so as to enable the vibrating assembly to be readily restarted. The holding assembly can incorporate a robot arm for transporting and positioning the intermediate molded product for runner removal. In order to protect the robot arm from the effects of vibrational forces, the intermediate molded product is adapted to be resiliently attached to the robot arm.

Abstract: A robot hand that comprises a coupling member releasably mounted on a robot body and a holding member for holding a workpiece. The coupling member and the holding member are coupled through elastic members so that external force and vibration received by the workpiece can be absorbed by the elastic members.
