In this embodiment, the transfer drive arm 10 is moved by the two pinions 8, 9 provided at a predetermined interval in the width direction of the automatic transport vehicle 1 as described above. Even if the end of the transfer drive arm 10 passes through the pinion 8 on the upstream side in the direction, the transfer drive arm 10 meshed with the pinion 9 on the downstream side in the movement direction is further moved. Compared to the system in which one pinion is provided at the center of the carrier, the moving amount can be increased, and the moving tank truck 32 can be completely transferred to the position of the kitchen on the station stand.

Further, in this embodiment, in order to prevent the swinging of the automatic transport vehicle and the transfer drive arm, and the transfer drive arm and the transfer driven arm, and perform safe traveling and transfer, the transfer is performed. Support members are provided on both sides in the width direction of the driving arm, and longitudinal grooves are provided on both sides of the respective support portions, and support portions are provided on both sides in the width direction of the transfer driven arm. A number of guide rollers are provided inside each support portion, and the guide rollers are supported by two rail-shaped protrusions provided at predetermined intervals in the transport vehicle in the longitudinal direction to support the transfer drive arm. Since the guide roller of the transfer driven arm and the guide roller of the rail-shaped protrusion of the carrier are loosely fitted in the grooves on both sides of the section,
Even when a moving tank truck with a heavy moving tank is placed on it, the claw provided at the center of the upper surface of the transfer driven arm causes the claw provided at the center of the transfer tank to engage with the transfer driven arm. Swing can be prevented.

[Effects of the Invention] In the transfer device for a moving tank truck according to the present invention, the transport vehicle loaded with the moving tank truck mounting the moving tank is sequentially guided to a plurality of process stations while being guided along a predetermined transport path. It moves and drives two pinions provided at predetermined intervals to move the transfer drive arm in the horizontal direction, and with this movement, the transfer drive that is detachable from the movable tank truck. The arm is moved in the same direction at the same time.
Since the connection line fixed to one end of the transport vehicle is fixed to one end of the transfer driven arm via a pulley disposed at the other end of the transfer drive arm, With the movement, the transfer driven arm moves about twice as long as the moving distance of the transfer drive arm. Since the transfer drive arm is moved by the two pinions provided at the predetermined interval, the end of the transfer drive arm passes through the pinion on the upstream side in the movement direction. However, since the transfer drive arm that meshes with the pinion on the downstream side in the movement direction is further moved, the moving distance of the transfer driven arm is smaller than in the method in which one pinion is provided on the carrier. And the moving tank truck can be completely transferred to a predetermined position on the station stand.

In the present invention, the moving tank mounted on the moving tank truck by operating the transfer device provided in the carrier,
The transfer from the transport vehicle to the station platform and from the station platform to the transport vehicle via the movable tank truck can be freely performed, so the operating rate of the transport vehicle and the movable tank is improved, and efficient batch production is possible.
