In this transport device, an unmanned transport vehicle b is dipped under a carriage a, and a tow pin c thereof is raised to engage with the carriage a. A guard bar d is arranged at the front part of the carriage a, and when the bar d hits an obstacle, the traveling of the automatic guided vehicle b is automatically stopped. That is, in such a case, the arm e integrated with the guard bar d
Is rotated in the direction of arrow B in the figure, and the reflection plate f attached to the tip thereof is separated from the photoelectric sensor g of the automatic guided vehicle b to block the light incident on the sensor g.

せるようにしてある。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a carrying device of the present invention. In the figure, 1 is a dolly, and the dolly 1 is a pair of left and right casters 2.
It has two front and rear. A bumper 3 is arranged in front of the carriage 1, and a tape switch 4 is attached to the front surface of the bumper 3. A shock absorbing material is filled inside the bumper 3. 5 is an automatic guided vehicle, and the guided vehicle 5
Is sunk under the top plate 6 of the carriage 1 and connected to the carriage 1. That is, the automated guided vehicle 1 is provided with a pair of pulling pins 7 that can be moved up and down on the upper surface of the rear part.
It is engaged with a connector 8 fixed to the top plate 6. Further, an electromagnetic solenoid (transmission means) 9 is installed on the lower surface of the top plate 6 of the carriage 1, and a magnetic sensor (reception means) 10 is installed on the upper surface of the automatic guided vehicle 1 directly below the solenoid 9. . When the bumper 3 hits an obstacle, the tape switch 4 is turned on to excite the electromagnetic solenoid 9, while the magnetic sensor 10 detects the magnetic field generated by the solenoid and controls the detection signal of the sensor 10. A means (not shown) is received to stop the traveling of the automatic guided vehicle 5.

光電センサーで行なってもよい。In this embodiment, signal transmission between the carriage 1 and the automatic guided vehicle 5 is performed by the electromagnetic solenoid 9 and the magnetic sensor 1.
However, this signal transmission may be performed by other means, for example, a photoelectric sensor.

止しなくなり、装置の信頼性が向上する。According to the present invention, since the guard bar and the arm conventionally installed in the front part of the trolley are not required, a space is created and the degree of freedom in design is improved. Furthermore, since the signal transmission between the carriage and the automatic guided vehicle is not performed by a mechanical method, the automatic guided vehicle does not stop unintentionally during traveling, and the reliability of the device is improved.
