Stop and return mechanism for workpieces in factory has housing containing pawl on levers forming parallelogram linkage connected to actuator cylinder

摘要

A rod connected to a linear actuator cylinder (1) may push the housing (2) for the pawl (3) along a guide rail (4). The housing may run on a roller or a sliding shoe (5). The pawl is mounted on two parallel links (9,10), and the bottom link may be tilted to raise and lower the pawl by a pneumatic actuator (7) with an air supply line (8).
