An operation control system for automated guided vehicles conveying articles along an unmanned conveying system. This operational control system comprises a first travel path loop and a second travel path loop along which a first group and a second group of the automated guided vehicles are automatically travelled. A common travel path is provided along which the automated guided vehicles of both the first and the second group are travelled, to enable a transfer of articles between the groups of automated guided vehicles. Also a correlating unit for correlating one automated guided vehicle of the first group with another automated guided vehicle of the second group, and a transfer control unit for controlling the transfer of the articles between the automated guided vehicles are provided. The transfer control unit permits only a transfer of articles between automated guided vehicles correlated with each other by the correlating unit.

Operation control system for automated guide vehicles

A travel control device for an unmanned vehicle automatically travelling along a predetermined travel path. The travel control device comprises non-contact type and contact type obstacle sensors for detecting an obstacle in front of the unmanned vehicle, and the unmanned vehicle is stopped when an obstacle is detected. A working area is predetermined along the travel path, and entrance and exit marks are provided to indicate the working area. When the unmanned vehicle enters the working area, a detection of signals output by the non-contact type obstacle sensor is disabled, to avoid unnecessary stops in the specific area and maintain a smooth travel of the unmanned vehicle. Further, a time counter is provided for counting a time from when the unmanned vehicle is stopped to a time when the unmanned vehicle is restarted, and when the unmanned vehicle is restarted, the unmanned vehicle is caused to travel at a speed higher than a previous speed at which it was travelling before being stopped, to recover a delay time incurred by the stop.
