Abstract
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.
