PURPOSE:To contrive the saving of space omitting or miniaturizing an automatic feeder by providing a movable stopper, which restricts a robot from intruding into a delivery location, in a rail base bed side part inner from a rail running end. CONSTITUTION:When an operator controls a button, a movable stopper 9 swivels its another end to be erected from the laid position to the vertical upper by actuating an air cylinder 10, and this other end is adapted to and detected by a detector 11a while locked to its position by stopping the air cylinder 10 following this detection. While synchronizing with the air cylinder 10, also the second air cylinder 12 is actuated, and by this action, a safety fence 8 moves to a position of the movable stopper 9, ensuring work space enough for the worker to safely arrange a workpiece in a line D on a work station. Accordingly, it is only required for the worker to directly arrange the workpiece in the line D on the work station, and an automatic feeder can be omitted. |
