ABSTRACT:
A positive-acting coupling device for rigidly coupling a product-carrying dolly to the shuttle carriage of a high speed indexing conveyor is disclosed. Intercoupling of the carriage and the dolly is effected by a pair of clamp arms carried by the carriage which close against the opposed contact surfaces of a striker bar that projects from beneath the dolly. A cam mechanism on the carriage is operated by remotely mounted pneumatic cylinders located at positions along the conveyor where it is desired to either open or close the clamp arms. The cam mechanism is self-locking in the closed position of the clamp so that only a momentary actuating force applied by a cylinder is required. Since the clamp arms are closed against the opposed contact surfaces of the striker bar, no relative movement of the product-carrying dolly and the shuttle carriage is permitted.
