When installing the rail device 30 as described above, it should be possible to install the body side mounting tool 61 and the ceiling side mounting tool 70 without considering intrusion into the machine frame. And the self-propelled car is
The propulsion rotary wheel 16, which rotates to the right or left of the self-propelled vehicle center 22 depending on the running direction, is attached to the rack attachment/detachment portion 32.
It rolls in pressure contact with one of the friction rolling surfaces 36 of D. Further, in the inclined path portion and the vertical path portion, a rack 38 is attached to the remaining rack attachment/detachment portion 32D that is not used for the one-friction rolling surface 36, and the pinion gear +7 can freely engage with this rack 38.

Next, in the above example, a self-driving car! Explain the driving work.

When the self-propelled vehicle 1 is running, the rotational force of the motor 10 is transferred to the deceleration device 14.
, is transmitted to the propulsion rotary wheel 16 via the drive shaft 15, and the propulsion rotary wheel 16 is pressed and rolled on the friction rolling surface 36. Traveling to this point involves the rotation i1 [11 of the first wheel 4 with respect to the first travel guide face 34 and the second travel guide face 3
1 of the second wheel 7 with respect to 5; and the roll of the lateral movement regulating wheels 8.9 with respect to the third travel guide surface 37, the vehicle can move along a fixed path 5, such as a horizontal or inclined path, without shaking. The first thing to do is to be stable. In the ascending and descending inclined path portions and vertical path portions, the pinion gear 17 engages with the recess 38, so that slip-free running can be achieved.

During such running, if the coils 44 and 45 are not energized, the pole plates (convex portions) 43A and 43 of both stages
Sensors 19 and 20 passing between B do not receive the stop signal. However, as shown in FIG. 7, since the sensor 46 detects the foundation bundle (self-propelled vehicle signal) A formed vertically from the permanent magnet 21, the location where this sensor 46 is installed is It is detected that the vehicle has passed (that the vehicle is present in the section), and the detection signal is given to the control unit. 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, as shown in Figures 1, 4, and 6,
A left and right bundle (stop signal) B will be formed between the upper ends of both output plates 43A and 43B, so the sensors 19 and 20 that have moved together with the self-propelled vehicle 1 will detect the output bundle B. Therefore, 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 suspension, the permanent cornerstone 21
faces the sensor 46, detects Tazuka A in the same manner as described above, and the control unit detects the stoppage.

When driving on a curved route, the self-propelled vehicle l is swung outward due to centrifugal force, causing sensors 19 and 20 and permanent foundation stones 21 to
The magnetic pole plates 43A, 43B and the convex portions 50A, 50B on the outside are formed to be low at this time, as shown in Fig. 1, so no collision occurs between them. .

By removing the insulating covers 49 and 49m, it is possible to clean the inside of the equipment arrangement section 33, inspect and confirm the rail-side equipment 42, replace the rail-side equipment 42, change the arrangement position, etc.

In the above embodiment, sensors 19.2 are installed at both the front and rear ends of the self-propelled vehicle l.
0 is attached, but kneading may be done only on one side.

By attaching two, the rear one will work better in the event of an overrun, and it will also be possible to run both forward and backward.

In the above embodiment, the rail side equipment 42 is a set of coils 44, 45 and sensors 46;
6 may be arranged separately.

Effects of the Invention According to the present invention having the above configuration, the inner surfaces of the pair of left and right rack attachment/detachment parts are used as the friction rolling surfaces of the propulsion wheels of a self-propelled vehicle, so that the rail device can be attached to the machine frame. When rolling, it is possible to perform the desired running using one of the friction rolling surfaces, and on vertical or sloping routes, the rack attachment/detachment section of the other side, which is not used for friction rolling, can be used. The rack can be easily and firmly attached to the pinion gear of a self-propelled vehicle. As a result, the rail device can be easily installed without having to think about its orientation, and furthermore, if it is made into a unit as a transfer device, the volatile content can be halved and inventory can be reduced. λro.
