PURPOSE:To efficiently operate plural unattended vehicles by starting the unattended vehicle whose charging time is longest out of unattended vehicles in all charging stations to the next process area based on arrival of an unattended vehicle at a charging area at the time of charging unattended vehicles in all charging stations of the charging area. CONSTITUTION:Charging stations 7 to 9 provided with chargers 7a to 9a are arranged in a charging area 4 on the outside of a guide line 3. A control board 12 which collectively controls these chargers 7a to 9a is provided on the side of these chargers. If unattended vehicles 2 are charged in all charging stations of the charging area 4 at the time of arrival of an unattended vehicle 2 at the charging area 4, the unattended vehicle 2 whose charging time is longest among unattended vehicles in all charging stations is started to a parts loading area. When the started unattended vehicle departs from the charging area 4, the arriving unattended vehicle 2 is guided to the charging station and is charged. Thus, the number of unattended vehicles on a running course other than the charging area is kept constant to efficiently operate plural unattended vehicles. |
