Abstract: A rollup barrier is provided for a robotic station. The barrier includes a track having a tapered portion at its lower end. A switch is mounted at the extreme lower end of the track. The switch prevents actuation of the robotic equipment unless the barrier is moved to its extreme lowermost position. Extensible cylinders are used for connection to a chain trained around a sprocket in order to roll the roller.

Abstract: The invention relates to a work piece holder with top mounted robot which optimizes floor space for a work piece positioner and a robot. In general, the work piece positioner assembly and the top mounted robot is supported on a base frame. Attached to the base frame, is a first superstructure and a second superstructure which supports a work piece positioner and the top mounted robot. Above the first superstructure and second superstructure is a frame structure fixed in the unitary assembly to the first superstructure and the second superstructure. Attached to the frame structure is a robot stand and a robot. Due to the unique shape of the work piece holder with top mounted robot, the floor space of the combined robot and work piece positioner is significantly reduced, and the overall cost of the system is reduced.
