Claims

[Scope of Claim for Utility Model Registration] (1) Transportation by an unmanned vehicle that is stopped at a predetermined cargo delivery stop position in front of a ground-side receiving platform and where cargo is delivered between the ground-side receiving platform and the unmanned vehicle. In the system, the unmanned vehicle is equipped with a reflective photoelectric detector to determine the presence or absence of cargo on the ground-side loading platform. , the reflector is held in a position that does not directly face the front of the reflective photoelectric detector when the unmanned vehicle is stopped at the cargo delivery stop position, and when there is a cargo on the ground side cargo receiving platform, the reflector is The ground side of a transportation system using an unmanned vehicle, which is provided with a reflector device comprising a reflector holding means that is held in a position directly facing the front surface of a reflective photoelectric detector when the unmanned vehicle is stopped at a cargo delivery stop position. Load detection device on the loading platform. (2) When the reflector device rotatably supports the reflector and the reflector around a horizontal axis extending in the left-right direction of the ground-side loading platform, and there is no load on the ground-side loading platform, the reflector is supported by an unmanned vehicle. A reflector support mechanism that holds the reflector in a position that does not directly face the front of the reflective photoelectric detector when stopped at the cargo delivery stop position, and a reflector support mechanism that holds the reflector in a position that does not directly face the front of the reflective photoelectric detector when stopped at the cargo delivery stop position. 2. A ground transport system using an unmanned vehicle according to claim 1, further comprising a reflector actuating member which is actuated by a load and rotates the reflector to a position where it directly faces the front surface of the reflective photoelectric detector and holds the reflector at that position. Load detection device on the side load tray. (3) When the reflector device rotatably supports the reflector and the reflector around a horizontal axis extending in the left-right direction of the ground-side loading platform, and there is no load on the ground-side loading platform, the reflector is supported by an unmanned vehicle. A reflector support mechanism that holds the reflector in a position that does not directly face the front of the reflective photoelectric detector when stopped at the cargo delivery stop position, and when a load is placed on the ground side cargo receiving platform from the front of the receiving platform. 2. A ground transport system using an unmanned vehicle according to claim 1, further comprising a reflector actuating member which is actuated by a load and rotates the reflector to a position where it directly faces the front surface of the reflective photoelectric detector and holds the reflector at that position. Load detection device on the side load tray. (4) When the reflector device rotatably supports the first reflector, the second reflector, and both reflectors around a horizontal axis extending in the left-right direction of the ground-side cargo platform, and there is no load on the ground-side cargo platform. In addition, there is a reflector support mechanism that holds both reflectors in a position that does not directly face the front of the reflective photoelectric detector when the unmanned vehicle is stopped at the cargo delivery stop position, and a reflector support mechanism that holds both reflectors in a position that does not directly face the front of the reflective photoelectric detector when the unmanned vehicle is stopped at the cargo delivery stop position, and a a first reflector actuating member that is activated by the load and rotates the first reflector to a position directly facing the front surface of the reflective photoelectric detector and holds the first reflector in that position when a load is placed on the ground side load receiver; When a load is placed on the platform from the front of the loading platform, the second reflector is activated by the load to rotate the second reflector to a position directly facing the front of the reflective photoelectric detector and hold it at that position. 2. A load detection device on a ground-side load receiving platform in a transportation system using an unmanned vehicle according to claim 1.
