Next, the traveling operation of the self-propelled vehicle 1 in the above embodiment will be explained.

When the self-propelled vehicle 1 runs, the rotational force of the motor 10 is transmitted to the propulsion rotating wheel 16 via the deceleration device 14 and the drive shaft 15.
and transfers this propulsion rotating wheel 16 to the friction rolling surface 3
This can be done by pressing and rolling on 6. At this time, traveling is caused by the rolling of the first wheel 4 against the first travel guide surface 34 and the rolling of the second wheel 7 against the second travel guide surface 35.
, and the rolling of the lateral movement regulating wheels 8 and 9 relative to the third traveling guide surface 37, the vehicle is stably moved along a fixed path 5, such as a horizontal or inclined path, without any shaking. On the ascending and descending slope paths, the pinion gear 17 engages with the rack 38, allowing the vehicle to travel without slipping.

During such traveling, the coils 44, 45
When not energized, the sensors 19 and 20 that pass between the two magnetic pole plates (protrusions) 43A and 43B
does not receive a stop signal. However, as shown in FIG. 7, since the sensor 46 detects the magnetic flux (self-propelled vehicle signal) A generated in the vertical direction from the permanent magnet 21, the self-propelled vehicle 1 Passing (being present in a certain section) is detected, and the detection signal is given to the control section. When the designated self-propelled vehicle 1 is stopped at a designated location (station), the coils 44 and 45 corresponding to the designated location are energized before the self-propelled vehicle 1 arrives. Then the first
As shown in FIGS. 4 and 6, both magnetic pole plates 43
A horizontal magnetic flux (stop signal) B is formed between the upper ends of A and 43B, and therefore the sensors 19 and 20, which have moved together with the self-propelled vehicle 1, detect the magnetic flux B. The motor 10 is stopped and the brake is applied. As a result, the self-propelled vehicle 1 is stopped after traveling the braking distance. Due to this stop, the permanent magnet 21 faces the sensor 46, detects the magnetic flux A in the same manner as described above, and the control unit confirms the stop.

When driving on a curved route, centrifugal force causes the self-propelled vehicle 1 to
is swung outward, and the sensors 19, 20 and the permanent magnet 21 also move outward, but at this time, as shown in FIG. 1, the magnetic pole plates 43A, 43
Since the outside of B and the convex portions 50A and 50B are formed low, no collision occurs between them.

By removing the insulating covers 49, 49a, it is possible to clean the inside of the equipment placement section 33 through the opening 31 and the slit 39, inspect and confirm the rail-side travel control device 42, and replace or install the rail-side travel control device 42. You can make changes, etc.

In the above embodiment, the sensors 19 and 20 are attached to both the front and rear ends of the self-propelled vehicle 1, but they may be attached only to one side. By attaching two of them, the rear one will work better in the event of an overrun, and it will be possible to travel both forward and backward.

In the above embodiment, the rail side equipment 42 includes the coil 4
4 and 45, the sensor 46 is provided as a set, but the sensor 46 may be provided separately.

Effects of the Invention According to the present invention having the above configuration, a self-propelled vehicle can be guided by a rail device and run on a fixed route. At this time, by transmitting and receiving control signals using magnetic flux, for example, between the travel control devices on the rail side and on the self-propelled vehicle side, contactless control that does not generate wear or dust can be performed. By removing the insulating cover, it is possible to easily arrange, maintain, and inspect rail-side travel control equipment, etc., and clean the inside of the equipment arrangement section through the opening and the slit. Also, on a curved route, even if the self-propelled vehicle's control equipment moves laterally due to centrifugal force,
This means that the vehicle will not collide with the protrusions formed low, allowing for smooth running.
