<p>The cylinder has a central recess for retaining a feed nipple (3) arranged at a lower side of a work piece pallet. A set of locking bodies (5) locks the feed nipple in a housing (10) in a spring-loaded manner, where the feed nipple is unlocked by moving a locking piston (6). An actuating element (15) is arranged in a movement path of a spring assembly (8), where an actuating signal of the actuating element is monitored. Another actuating element is connected upstream to a signal flow of the former actuating element and detects a displacement condition of the feed nipple.</p> |
