Next, the operation of the above embodiment will be explained.

When moving the target vehicle 72 placed on the moving platform 53 disposed in the storage space 52 to the entrance/exit lower 3, each moving platform 53...
- The X-axis drive motor 63a and the Y-axis drive motor 133b, which are disposed below, are controlled by, for example, a computer. The mobile platform 53
To explain the movement in detail with reference to FIG. 9, when moving the moving/υJ platform 53 carrying the target vehicle 72 in the direction of the arrow 74, which is the Y-axis direction 55,
A moving platform 53' located in front of the moving direction is moved in the X-axis direction 54 or the Y-axis direction 55 to move the target moving bra.

A moving space 56 is formed in front of which the platform 53 is about to move. After the movement space 5G is thus formed in the traveling direction, the Y-axis drive motor 63b is driven, and the Y-axis direction conveyance drive roller 1.1 rotates. When these Y-axis direction transport drive rollers 1.1 are stopped, the cutout surfaces 7 face upward and are not in contact with the surface 8 of the moving platform, but when rotated in this way, the circular outer periphery Surface 6 is in frictional contact with surface 8 and causes movement platform 53 to move. In this way, the Y-axis conveyance drive roller 1.1 rotates to move the moving bluff (platform 53).

When moving in the direction of arrow 74 in Fig. 9, the pit 61
From the Y-axis direction conveyance drive roller 1 arranged on the left side of
Even when the moving platform 53 leaves, the moving platform 53 moves to the next moving place, the pit 61'.
It is not positioned correctly on the top. Since the moving platform 53 has inertia to move in the direction of arrow 74, which is the direction of movement, it will eventually be located at the next location, but it will move in the Y-axis direction located inside the bit 61'. If the drive mechanism 60 moves this moving platform 53 following the operation of the Y-axis direction drive mechanism in the front position, it can be reliably moved to the desired position 1t.

The above example shows the case where the target mobile plant home 53 is moved by one in the Y-axis direction, but when moving it in the X-axis direction, the X-axis drive motor 133a is driven and the same movement is performed. The platform 53 is moved in the X-axis direction.

In this way, the target moving platform 53 can be moved up to the entrance/exit lower 3 while sequentially moving in the X-axis direction 54 and the Y-axis direction 55. When moving the moving platform 53 in the X-axis direction 54,
As described above, when rotating the X-axis direction conveyance drive roller 1a and moving in the Y-axis direction 55, the Y-axis direction conveyance drive roller 1 is rotated, but the X-axis direction conveyance drive roller 1a is rotated. When the moving platform 53 is moved in the X-axis direction, the surface 8 of the moving platform may be in frictional contact with the outer peripheral surface of the Y-axis direction conveyance drive roller 1, or the Y-axis direction drive roller 1 may be
When the moving platform 53 is moved in the Y-axis direction by rotating the Unable to move smoothly. For this reason, conventionally, when using one and the other conveyance drive rollers for conveying in two directions, when one conveyance drive roller is in frictional contact with the surface, the other conveyance drive roller is removed from the surface. A separation step was necessary to allow the separation.

However, in this case, since the notch surface 7 is formed in a part of the circular outer circumferential surface 6 of the conveyance drive roller 1, the conveyance drive roller 1 is simply stopped by sealing the notch surface 7 to the surface 8. Then, the outer peripheral surface 4 is set at a predetermined distance Δ with respect to the surface 8.
They can be separated by t. For that reason, @ contact / [
No stage is required, and the configuration of the device can be simplified.

In the second embodiment, an example was shown in which the transport drive roller 1 was disposed below the moving platform 53, but as shown in FIG. It may be arranged above 5.

〔Effect of the invention〕

As described in detail above, the present invention has ■ a part of the circular outer circumferential surface 6;
Since the notch surface 7 is formed so that it can be separated from the surface 8 of the workpiece, article, etc. 5 by a distance Δt, if the notch surface 7 is directed toward the surface 8 of the workpiece, article, etc. 45, the notch surface 7 is stopped. The outer circumferential surface 4 can be brought into contact with and separated from the surface 8 of the workpiece, article, etc., so that the outer circumferential surface 4 of the conveyance drive roller can be moved away from the surface 8 of the workpiece, article, etc.

There is no need for an RA or a contact means to move the article, etc. toward or away from the surface 8. Therefore, ■The entire conveying device can be constructed easily and compactly, and ■The conveying device The present invention has various advantages such as providing a conveyance drive roller for workpieces, articles, etc., which can reduce design and manufacturing costs.
