(2)ドローン30が備えるアンテナ方向調整装置37は、給電車両50とドローン30の位置関係に基づいて、受電アンテナ32の向きを調整する。すなわち、アンテナ方向調整装置37は、ドローン30に対する給電車両50の相対的な位置に応じて、受電アンテナ32の向きを調整する。このため、給電車両50の相対的な位置に関係なく受電アンテナ32の向きが固定された構成に比べて、給電アンテナ51から送られたマイクロ波の受電効率を高めることができる。したがって、ドローン30の稼働時間を向上でき、かつ、マイクロ波で効率良く給電できる。 (2) The antenna direction adjusting device 37 included in the drone 30 adjusts the direction of the power receiving antenna 32 based on the positional relationship between the power feeding vehicle 50 and the drone 30. That is, the antenna direction adjusting device 37 adjusts the direction of the power receiving antenna 32 according to the relative position of the power feeding vehicle 50 with respect to the drone 30. Therefore, the power receiving efficiency of the microwave transmitted from the feeding antenna 51 can be improved as compared with the configuration in which the orientation of the power receiving antenna 32 is fixed regardless of the relative position of the feeding vehicle 50. Therefore, the operating time of the drone 30 can be improved, and the power can be efficiently supplied by microwaves.

(3)給電車両50は、ドローン30に追従して移動するため、移動中のドローン30の近傍からマイクロ波を送ることができ、より効率良く給電できる。 (3) Since the power feeding vehicle 50 moves following the drone 30, microwaves can be sent from the vicinity of the moving drone 30, and power can be supplied more efficiently.

That is, the cargo handling vehicle may be, for example, an automatic guided vehicle equipped with a transfer device other than the fork F, or an automatic guided vehicle without a transfer device, and is an automatic guided vehicle or an image recognition type automatic guided vehicle. It may be.

・給電車両50が、搬送車両10の機能を備えるように構成してもよい。すなわち、給電車両50が、荷役を行う荷役車両を兼ねていてもよい。この構成によれば、給電車両50は、この給電車両50による荷役の支援を行うドローン30に対して給電を行うことができる。 The power feeding vehicle 50 may be configured to have the function of the transport vehicle 10. That is, the power feeding vehicle 50 may also serve as a cargo handling vehicle that performs cargo handling. According to this configuration, the power feeding vehicle 50 can supply power to the drone 30 that supports cargo handling by the power feeding vehicle 50.

・ドローン30に代えて、荷役を行う無人飛行体を採用してもよい。すなわち、無人飛行体が荷役車両による荷役の支援を行わず、無人飛行体自身が荷役を行うように構成してもよい。 -Instead of the drone 30, an unmanned aerial vehicle that handles cargo may be adopted. That is, the unmanned aerial vehicle may be configured so that the unmanned aerial vehicle itself does not support the cargo handling by the cargo handling vehicle.
