<p>PROBLEM TO BE SOLVED: To provide a crossbar switching system that can switch a crossbar by attaching and detaching the crossbar quickly and smoothly between a workpiece transport device and a crossbar switching device.SOLUTION: A switching system of the present invention is provided for switching a crossbar between a workpiece transport device for transporting the workpiece W by the crossbar and a crossbar switching device. The switching system is characterized by: using a crossbar 100 in which both ends 120 can be switched between a relatively rotatable state and a relatively non-rotatable state to a central part 110; directing a mounting surface 131 of the crossbar substantially in the horizontal direction by providing a rotation angle phase difference between both ends and the central part, when a workpiece transport device 300 moves for bringing the crossbar to a crossbar switching device 200; and eliminating the rotation angle phase difference after mounting the crossbar while directing a crossbar mounting surface 321 substantially in the horizontal direction, when the workpiece transport device moves for receiving the crossbar to the crossbar switching device 200.</p> |
