PROBLEM TO BE SOLVED: To provide an unmanned transportation vehicle system in which it is not required to carry out charging while leaving transportation work in a circulation passage, or to replace power storage means.SOLUTION: An unmanned transportation vehicle system S1 includes a preset circulation passage R, an unmanned transportation vehicle V travelling automatically therealong, and stopping at multiple stop positions H, and power transmission devices A placed at respective stop positions H. The unmanned transportation vehicle V includes a power reception device B for receiving power, in non-contact, from the power transmission device A during stoppage and outputting while rectifying, a capacitor 6 for accumulating power outputted therefrom, and a motor 8 being driven with power from the capacitor 6. By power transmission at the stop positions H, the capacitor 6 is charged from a first voltage Vc1 to a second voltage Vc2, and the distance Dx between the stop positions H is set to satisfy a relation Dx≤X×α×Cc×(Vc2-Vc1)/(2×Id×Vd), where capacitance of the capacitor 6 is Cc, a predetermined factor is α, travel speed of the unmanned transportation vehicle V is X, driving voltage of the motor 8 is Vd, and the driving current is Id.SELECTED DRAWING: Figure 1
【課題】循環経路での搬送作業から外れて充電を行ったり、蓄電手段を交換する必要がない無人搬送車システムを提供する。【解決手段】無人搬送車システムS1において、予め設定された循環経路Rと、これに沿って自動走行し、複数の停止位置Hで停止する無人搬送車Vと、各停止位置Hに配置された送電装置Aとを備えた。無人搬送車Vは、停止中に送電装置Aから非接触で受電し、整流して出力する受電装置Bと、これが出力した電力を蓄積するキャパシタ6と、キャパシタ6からの電力で駆動されるモータ8とを備えている。停止位置Hでの送電によって、キャパシタ6を第1電圧Vc1から第2電圧Vc2になるまで充電し、キャパシタ6の静電容量をCc、所定の係数をα、無人搬送車Vの走行速度をX、モータ8の駆動電圧をVd、駆動電流をIdとした場合、停止位置H間の距離Dxは、Dx≦X・α・Cc・(Vc22−Vc12)/(2・Id・Vd)に設定される。【選択図】図1
