<Operation> Next, the operation of the rotary table device 10 will be described.

As shown in Fig. 1, the turntable 30 on which the driver stops the car
The vehicle is advanced at a low speed to and the front wheels A, A'are driven onto the first correction rollers 40, 40 as shown in FIG.

When the front wheels A, A'of the vehicle ride on and pass over the first correction roller 40, the sensor 70 shown in FIG.
The midpoint P1 between A'is detected.

When the midpoint P1 is out of the center line L1 of the turntable 30, a drive signal is output from the control circuit 80 to the drive unit 60, and all the rollers 41, 42 forming the first correction roller 40. …
Rotate in the correcting direction all at once and forcibly move the front wheels A and A '.

When the midpoint P1 of the front wheels A and A'matches the center line L1 of the turntable 30, the rotation of the first correction roller 40 is stopped.

When the front wheels A and A'override the first correction roller 40 and ride on the second correction roller 50, the second correction roller 50 operates in the same manner as the first correction roller 40 so that the midpoint P1 of the front wheels A and A'is changed. The entry position is forcibly corrected until it coincides with the center line L1 of the turntable 30.

Then, as shown in FIG. 5, when the rear wheels B, B'following the first correction roller 40 are loaded, the midpoint P2 of the rear wheels B, B'is set on the rotary table as in the case of the front wheels A, A '. It is forcibly fed by the first correction roller 40 until it coincides with the center line L of 30.

In this way, even when the vehicle gets in slightly off the center line L of the turntable 30, the front wheels A and A'and the rear wheels B and B'are automatically corrected by the first and second correction rollers, respectively. To be done.

When the rear wheels B, B'of the vehicle have entered the first correction roller 40, the vehicle is stopped and the parking brake is set to get off.

After that, the rotary table 30 rotates toward the loading / unloading port 20 as in the conventional case, and is moved into the loading / unloading port 20 by, for example, a transfer device (not shown).

Further, it is naturally conceivable that the driver moves the automobile into the entrance / exit port 20 without using the carrier device.

<Effects of the Present Invention> Since the present invention is as described above, the following effects can be obtained.

<a> Since the mounting position of the automobile can be corrected by roller feeding, even an inexperienced driver can easily get into the correct position at one time.
