 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1 to FIG. 3, reference numeral 1 is a conveying device, which has a first conveyor means 3 on the side of a station 2 and a second conveyor means 4 and is connected to one end of the first conveyor means 3 Between the 1st conveyor means 3 and the 2nd conveyor means 4, it is provided with the conveyance vehicle 7 which delivers the work 6 mounted on the pallet 5.

The carrier 7 has a second conveyor means 4 mounted on the upper side of a carriage 8 via a frame 9. A conveyor belt 4b is wound around the second conveyor means 4 so as to rotate the plurality of rollers 4a, 4a .... The conveyor belt 4b is also wound around the roller 11 which is rotationally driven by the air motor 10 and is rotationally driven by the air motor 10.

Optical communication devices 12 and 13 are respectively arranged on one end of the first conveyor means 3 and on an end side of the carrier vehicle 7 connected to the first conveyor means 3, and the carrier vehicle 7 is the first. The approach to the conveyor means 3 is detected. Further, an air source (not shown) is connected through an air hose 14 to one end of the first conveyor means 3 and the central portion of the end of the transport vehicle 7 connected to the first conveyor means 3. An air connector 16 that can be moved forward and backward by the cylinder means 15 and an air coupler 17 that can be detachably connected to the air connector 16 are provided.

Further, the first conveyor means 3 has connection arms 21 and 22 on both sides of one end side, and when the transport vehicle 7 approaches the first conveyor means 3 and the optical communication devices 12 and 13 react. , The connection arms 21 and 22 are releasably engaged with the projections 25 and 26 of the transport vehicle 7 by the force from the hydraulic chambers 23 and 24, so that the transport vehicle 7 is connected to one end of the first conveyor means 3. To connect to.

Reference numeral 27 denotes a proximity sensor, which detects that the pallet has been transferred to the transport vehicle side.

According to the above configuration, when the transport vehicle 7 approaches the first conveyor means 3 on the station 2 side, the optical communication devices 12 and 13 react to detect the approach of the transport vehicle 7. As a result, the connection arms 21, 22 are releasably engaged with the projections 25, 26 of the transport vehicle 7 by the force from the hydraulic chambers 23, 24, so that the transport vehicle 7 is at one end of the first conveyor means 3. It is designed to connect to. At the same time, the operation of the cylinder means 15 causes the air connector 16 to pop out and engage with the air coupler 17 to supply air to the air motor 10.

As a result, the first and second conveyor means 3 and 4 are driven so that the work 6 placed on the pallet 5 is conveyed to the side of the conveyor vehicle 7 (second conveyor means 4). When it is conveyed, the proximity sensor 27 detects it, a stop signal is sent, the air supply is stopped, the connection between the air connector 16 and the air coupler 17 and the connection by the connection arms 21, 22 are released. .. Then, the transport vehicle 7 transports the work 6 to a predetermined position.

Therefore, it suffices to mount the air motor 10 on the transport vehicle 7 without providing an air source, which is advantageous in reducing the weight of the transport vehicle 7. Conventionally, the work 6 is transported onto the second conveyer means 4 by an electric motor using a battery for traveling a carrier vehicle. It can reduce the consumption of electricity and extend the battery life.

In the above embodiment, the drive source (air source) of the first conveyor means 3 is used to drive the air motor 10 which is the power means of the second conveyor means 4. The rotational force of the first conveyor means 3 can be directly received by the second conveyor means without providing a driving means such as an air motor.
