Abstract
Pickup device (24) is for mounting on the mounting plate of a positioning robot. The pickup device has a frame (30) which carries movable carriages (36, 38). Cam ring (50) controls the position of the carriages. Downwardly depending arms (60, 62) carry pairs of levers thereon. The levers have facing sloped cam surfaces (84, 86) which are spread by downward thrust of closing pin 88. When the closing pin drops too far, it indicates lack of grasp and this is signaled by contacts (114, 116).
