Abstract
A system includes an actuator, a barrier, and a linkage system connecting the barrier to the actuator and configured to move the barrier element between a retracted position and an extended position, and a stop arranged to inhibit a motion of the linkage system in a first direction when the barrier is in the extended position.
Claims17
A barrier system comprising:
- an actuator;
- a cam movably coupled to the actuator;
- a barrier;
- a linkage system connecting the barrier to the actuator and configured to move the barrier element between a retracted position and an extended position, the linkage system comprising a link having a first end and a second end;
- and
- a stop arranged to inhibit a motion of the linkage system in a first direction when the barrier is in the extended position,
- wherein the first end of the link is rotatably coupled to the cam, and
- wherein the second end of the link is rotatably coupled to the barrier.
5 more elements
A barrier system comprising:
- an actuator;
- a cam movably coupled to the actuator;
- a barrier;
- a linkage system connecting the barrier to the actuator and configured to move the barrier element between a retracted position and an extended position;
- a sensor configured to detect a position of the cam, and
- a stop arranged to inhibit a motion of the linkage system in a first direction when the barrier is in the extended position.
3 more elements
A method for controlling a movement of an object on a conveyor system, the method comprising:
- actuating an actuator to rotate a cam in a first direction, the cam connected to a barrier via a link, and
- detecting a position of the cam with a sensor,
- wherein the link moves the barrier to an extended position to extend beyond a roller element of the conveyor system, thereby obstructing a movement of the object conveyed by the conveyor system.
A system comprising:
- a conveyor system having at least one roller element;
- and
- a barrier system removably secured adjacent to the at least one roller element, the barrier system comprising:
- an actuator;
- a cam movably coupled to the actuator;
- a sensor configured to detect a position of the cam,
- a barrier;
- and
- a linkage system connecting the barrier to the actuator and configured to move the barrier between a retracted position and an extended position,
- wherein the barrier is configured to extend beyond the at least one roller element by a second predetermined distance when in the extended position.
