<p>PURPOSE:To provide an unattendant power supply for an unmanned vehicle in a clean room wherein installation is facilitated through compaction. CONSTITUTION:The unattendant power supply comprises a current collecting unit 50 mounted on an automatically guided vehicle(AGV) and a power supply unit 60 installed at a station. The current collecting unit 50 comprises a movable current collector 51 having a pair of AC and DC movable side contactors, a moving means 52 for the current collector 51, and an optical communication unit 53 on the AGV side. The power supply unit 60 is disposed oppositely to the current collecting unit 50 and comprises a fixed current collector 61 having a pair of fixed side contactors contacting at the moving end of the current collector 51, an optical communication unit 63 on the station side, and a power supply unit controller 64. When the AGV stops at the station, signals for starting/stopping the charging operation and moving the movable current collector 51 are communicated between the control section 40 and the controller 64 through the optical communication units 53, 63 and the current collectors 51, 61 come into contact to begin power supply. Contactors of the current collectors 51, 61 have contact surfaces crossing perpendicularly each other or inclining.</p> |
