Abstract: Systems, methods, and apparatus are provided for restricting access to articles on a conveyor. The apparatus includes a locking mechanism configured to move via a plurality of actuators, wherein at least two of the actuators move the locking mechanism in differing directions, and also configured to prevent removal of at least one article from the conveyor while in a locking position against the conveyor, wherein at least one of the actuators is configured to move the locking mechanism into the locking position.

Abstract: A locking apparatus configured to restrict access to articles on a conveyor, such as hooked members, by having a locking piece which, when mounted adjacent to a portion of the conveyor and moved to an extended position, the locking piece rests against the articles and conveyor, thereby preventing an operator from removing the articles from the conveyor. The movement of the locking piece can be automated by coupling each locking piece to an actuator which moves the locking piece to the extended position, and coupling each actuator to an air solenoid unit controlled by a computer system. A series of locking pieces used together selectively restrict access to articles suspended only from certain slots within a frame on the conveyor.
