43A, 43B.

The empty self-propelled vehicle 4 whose signals 49A and 49B have been adjusted to match the vehicle type signal stops at a body loading location 54.

Then, the body 53 is loaded via the transfer device 56, but if the body 53 is misaligned with respect to the transfer device 56 at that time, the body 53 that is mispositioned is The stop position of the self-propelled body 4 is corrected in the longitudinal direction (travel direction). As a result, the self-propelled body 4 is attached to the body 53.
can be correctly faced, and the desired loading can be carried out. At this time, the front amount is tool 35A.

35B serves as a reference point, and either one is used depending on the vehicle type. In the rear part, the movable amount of the rear part when raised is the tools 42A, 42B, and the movable amount of the rear part when raised is the tool 43A,
43B, and both rear movable receivers are tools 42A and 42B.

The amount of rear fixation when 43A and 43B are laid down is tool 4.
The positions of the receivers 9A and 49B are selected and used. In addition, the amount of movement of either rear part is the tool 42A,
When using 42B, 43A, 43B, there are some car models where the rear fixing amount is obstructed by the tools 49A, 49B, but in this case, the tip portions 49a, 49b will move back against the spring. .

Effects of the Invention According to the present invention having the above configuration, the self-propelled object collects current and sends/receives signals to and from the ground side via the sending/receiving device, runs supported and guided by the rails, and achieves the purpose. You can stop it wherever you want.

By using an actuating device, the movable rear part allows the tool to stand up or fall horizontally, and the fixed front part can be used in combination with tools to stably support various objects to be transported. At that time, in front of the loading location of the transported object, the above-mentioned signal exchange configuration gives the control panel a signal corresponding to the type of transported object to be loaded, so that this self-propelled body can move to the loading location. When the machine stops, it is already ready to receive and stop the corresponding object to be transported, and therefore the loading operation can be started immediately, making the entire operation more efficient. Immediately after stopping, the self-propelled body is moved forward or backward depending on the feeding position of the transported object.

Even if this supply position is disturbed, it can be corrected, and this eliminates the need for a positioning device or operation time for the transported object on the transfer device (supply device) side of the transported object. Piping and wiring can also be eliminated.
