<p>PROBLEM TO BE SOLVED: To enhance safety in connecting or disconnecting a receiving electrode part on a mobile robot side and a load dispatching electrode part on a stationary installation side. SOLUTION: The stationary installation where the mobile robot stops and operates is installed with an electric power supply comprising an alternating-current power supply 23 and load dispatching electrode part 24. Three load dispatching terminals 26 and an earth terminal 27 are installed in the load dispatching electrode part 24. The receiving electrode part 33, which is removably connected to the load dispatching electrode part 24 by being transited in the direction of appearance by a drive mechanism, is installed in an unmanned conveyance vehicle of a mobile robot. Three rod-like receiving terminals 44 and an earth terminal 45 are installed in the receiving electrode part 33. The earth terminal 45 is made longer than the other receiving terminals 44 and an pushing-in stroke for a base 43a is made larger. In case the receiving electrode part 33 is connected to the load dispatching electrode part 24, the earth terminals 45, 27 are connected before the connection of the receiving terminals 44 and the load dispatching terminals 26, while in case of the blow-off, a disconnection of the earth terminals 45, 27 are delayed than the disconnection of the receiving terminals 44 and the load dispatching terminals 26.</p> |
