Abstract: A positioning system includes a centrally mounted robot within a work area. Workpiece holders are independently moveable relative to the robot between working positions on opposite sides of the robot and a shared loading and unloading position. The system permits the robot to continuously operate without a need to wait for movement between the loading position and the working position. Furthermore, the system can be used as a single workpiece system while maintenance or hardware change is being performed on one of the workpiece holders. The workpiece holders move between the work positions and the loading and unloading position in a rotation and sliding fashion.

Abstract: A barrier for a robotic work station is provided and includes a pair of upright posts, and rigid panels which are movable between a lower open position and a raised closed position. The panels are simultaneously moved between the raised and lower positions by a pneumatic cylinder and a pulley system. The movable panels are cantilevered from one of the posts, and include rollers for movement within a channel in the post. A fixed panel is provided at the bottom of the posts and extends approximately to the top of the work station table.

Abstract: The invention relates to a rotational flash guard and method of use of a rotational flash guard. In general, the flash guard is attached to a support frame by an arm, a linkage mechanism pivotally interconnects the arm and the support frame, and an extensible power member connects the support frame to the linkage mechanism. Due to the unique configuration of the rotational flash guard it is adapted for movement about a work piece positioner to allow for use of a robotic tool while providing protection to the operator and other workers.

Abstract: A break away barrier utilizes first and second spaced apart upstanding posts positioned a predetermined safe distance away from the outer movement limit of a robot. A pair of barrier assemblies are hinged to the first and second spaced apart upstanding posts and are hinged for movement from a closed position inside the safe distance to an open position outside the safe distance. A break away latch permits the opening and separation of the first and second barriers in response to a predetermined force.

Abstract: A quick change fixture mounting arrangement includes a pair of mating ball-and-socket connectors at the headstock end of the fixture and a ball joint coupler at the tailstock end of the fixture. This arrangement allows for some misalignment of the fixture relative to the axis of rotation and permits the fixture to be rotated about a second, external axis of rotation.
