Abstract

A technique is described whereby a gripper attachment, for the IBM 7540 Robot or similar device, enables the gripper to pick up foam, rubber or other similar materials without the use of clamping or vacuum devices. Described herein, is the use of a pneumatically operated spear or barb- shaped cylinder rod which is used for puncturing and picking up the foam- or rubber-like product material. In prior art, the use of vacuum pick-up devices limited the use of foam or rubber to materials made of a closely packed cell structure. Using clamping methods required the thickness of the material to be controlled in the area where the clamp was applied. Also, the clamping devices required frequent changes and adjustments whenever the size of the foam product was changed. Therefore, the use of a spear-type gripper was devised.
