<p>PURPOSE:To realize the highly efficient transport of pallets by dividing the parts requests into two individual requests for real and empty pallets, dividing finely the working of an unmanned carrier to check the end of each divided job and allocating successively the transport requests in accordance with the loading state, the states of remaining jobs, etc. CONSTITUTION:The parts requests received from many parts request stations 3 are divided into the transport requests for real and empty pallets. The requests for empty pallets are immediately allocated to the available unmanned carriers 4 and carried out. While the parts requests for real pallets are allocated to the available carriers 4 at a time point when the real pallets storing the desired parts are delivered from an automatic storehouse 1 and after the end of the transport of empty pallets. Then these real pallet requests are carried out. In such a way, the availability is improved for the bed of an unmanned carrier and this carrier can be operated with high efficiency.</p> |
