 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view showing a traveling state of an unmanned vehicle transfer device according to an embodiment of the present invention. FIG. 2 is a rear view showing a state during transfer. The unmanned vehicle transfer device 1 is mainly composed of a table side conveyor 2, a vehicle side conveyor 3, a movable conveyor 4 and a holder 5. The platform side conveyor 2 is provided on the load receiving table 6, and in this example, it is a driving roller conveyor and is provided on an upper part of the load receiving table 6 installed in the vicinity of the traveling path 8 of the unmanned vehicle 7. is there. The carrying direction is a right-left direction (left-right direction in FIG. 1) perpendicular to the traveling direction of the unmanned vehicle 7. The car-side conveyor 3 is provided on the unmanned vehicle 7 and has a predetermined space C formed between the car-side conveyor 3 and the side of the load receiving table 6 to transfer the cargo A. In this example, a drive roller conveyor is used. , Is provided above the unmanned vehicle 7. The transport direction is the same as the conveyor 2 on the table side. The movable conveyor 4 is provided on the side of the unmanned vehicle 7 and extends from the guide side 2 and the vehicle side conveyor 3 to guide the luggage A to a storage position within the width W of the unmanned vehicle 7. In this example, the lever 9 is movable and is provided on the left side of the unmanned vehicle 7. The lever 9 is provided in the unmanned vehicle 7 so as to be capable of hoisting around the front-rear axis and has a substantially L-shape, and a drive provided on the lever 9. A roller conveyor 10, an electric cylinder 11 provided on the unmanned vehicle 7, and a pusher 12 provided on the unmanned vehicle 7 to oscillate the lever 9 by a so-called cam mechanism are provided. The holding body 5 is provided between the movable conveyor 4 and the side of the load receiving table 6 to hold the movable conveyor 4 at the guide position. In this example, the holding body 5 is provided on the table side conveyor 2 and the movable conveyor at the guide position. 4 is a channel material for supporting the free end of No. 4. Next, the operation will be described based on such a configuration. When the unmanned vehicle 7 is stopped in the vicinity of the predetermined receiving tray 6 and the load A is transferred between the platform side conveyor 2 and the vehicle side conveyor 3, the movable conveyor 4 is guided to the guide position as shown in FIG. It is placed and is extended between the base side conveyor 2 and the car side conveyor 3. That is, the pusher 12 is moved to the right due to the contraction of the electric cylinder 11 of the movable conveyor 4, the lever 9 and the driving roller conveyor 10 are lowered, and the driving roller conveyor 10 is fitted to the holding body 5 and kept in the same state.

Although the movable conveyor 4 is provided in the unmanned vehicle 7 in the above-described embodiment, the movable conveyor 4 is not limited to this and may be provided in the vehicle-side conveyor 3, for example. In the previous embodiment, the movable conveyor 4 is provided only on the left side of the unmanned vehicle 7, but the invention is not limited to this, and it may be provided on both the left and right sides, for example. Although the movable conveyor 4 is configured to move up and down in the previous embodiment, the movable conveyor 4 is not limited to this and may be moved linearly, for example. Although the movable conveyor 4 uses a so-called cam mechanism including the lever 9 and the pusher 12 in the above embodiment, the movable conveyor 4 is not limited to this, and an arm mechanism or the like may be used. As the movable conveyor 4, the drive roller conveyor 10 is used in the above embodiment, but the movable conveyor 4 is not limited to this, and a belt conveyor or the like may be used. Although the movable cylinder 4 uses the electric cylinder 11 in the above embodiment, the movable conveyor 4 is not limited to this, and may be a hydraulic cylinder or a pneumatic cylinder, for example. Although the holder 5 is provided on the table-side conveyor 2 in the previous embodiment, the holder 5 is not limited to this and may be provided, for example, on the movable conveyor 4 or the cargo receiving table 6. Although the interval C is formed between the holding body 5 and the unmanned vehicle 7 in the previous embodiment, the distance C is not limited to this.
