The vehicle is moved on the lateral rail 22 in the lateral direction (left or right when viewed from the automobile). Before the entire length of the turning rail 13 of the tray 10 is sent out, one end of the turning rail 13 (the end on the front side in the traveling direction of the tray 10) engages with the tray sending device 31 of the empty section, It is nipped by the rotating rollers 32, 32, 33, 33, and this is similarly sent out. When feeding of the entire length of the turning rail 13 is completed, the other end of the turning rail 13 (end on the front side in the traveling direction of the tray 10) is sent out by the tray feeding device 31 in the empty section, and is guided to the turning rail 13. Then, the spherical rollers 11 at the four corners of the tray 10 are further rolled on the pair of lateral rails 22, so that the tray 10
The whole is further moved laterally on the pair of lateral rails 22. In this way, when the rotation center of the rotation rail 13 is sent to the center position of the rotation base 37 of the empty compartment, the tray 10 is moved laterally by one tray. In the case of a plurality of trays 10, each tray 10 is moved sequentially or simultaneously in the same direction by the same operation.

On the contrary, when the rotating rail 13 of the tray 10 is not directed to the empty compartment, the tray feeding device 31 is used.
Is rotatably displaced by a rotating rail direction changing device 36 (one drive of the motor cylinder 38), and a pair of rotating rollers 32,
The turning rail 13 of the tray 10 sandwiched between 32, 33 and 33 is turned toward the empty compartment. It should be noted that when the rotation of the rotation rail 13 is started, the engagement between the locking projection 17 of the tray 10 and the locking recess 14 of the rotation rail 13 is released due to the movement of the rotation rail 13 in the rotation direction. To be done. In this way, the rotary rail 13 is rotated 90 degrees from the vertical direction or the horizontal direction of the tray moving rail 20 toward the horizontal direction or the vertical direction, and at the same time, the rotary rail 13 and the locking projection 17 of the locking device 16. The pivoting rail 13 is locked by elastic engagement with the locking recess 14 and the orientation of the rotary rail 13 is fixed. continue,
The tray feeding device 31 is operated, and one rotation roller 32, 32 on one side is rotationally driven by one drive of the drive motor 35, and is pressed and nipped between these rotation rollers 32, 32 and each rotation roller 33, 33 on the other side. The rotating rail 13 of the tray 10 has rotating rollers 32, 32, 33,
It is sent out in the rotation direction of 33. This sending operation is as described above. In the case of a plurality of trays 10, each tray 10 is moved sequentially or simultaneously in the same direction by the same operation.

In this way, one or a plurality of trays 1
By repeating the feeding operation of the tray 10 in which 0 moves toward the empty section in the vertical direction or the horizontal direction, the tray 10 for loading or unloading is moved to the lift 42. When the tray 10 for loading or unloading is placed on the lifting / lowering platform 43 of the lift 42, the lifting / lowering platform 43 is raised or lowered to the loading / unloading floor of the vehicle, and the vehicle is loaded or unloaded on the loading / unloading floor of the vehicle.

As described above, according to the above embodiment, the tray 10 is provided with the rotating rail 13 and the locking device 16 for the rotating rail 13 on the lower surface side, and the tray feeding device 30 installed on the tray moving rail 20 is provided. That is, the tray 1 is provided by the tray delivery device 31 and the turning rail direction changing device 36.
Since 0 is guided in the vertical direction or the horizontal direction on the horizontal plane and sent out, the number of parts can be significantly reduced compared to the conventional case, the installation and adjustment thereof can be simplified, and a significant cost reduction can be achieved. In particular, conventionally, many components such as a traveling-roller rotating rod were required to rotate the four traveling rollers, and synchronous control between the traveling rollers was required. However, in this embodiment, four rotation rollers are required. One roller
Rotation is driven by one drive motor and rotational displacement is performed by one motor cylinder, so not only the number of parts is greatly reduced, but also synchronous control of the rotating roller is not required, and installation adjustment can be simplified, resulting in an extremely large cost reduction. Can be planned.

Also, looking at the structure of each part of the apparatus, since the rotary rail 13 is formed of a square pipe or the like and is only pivotally supported at the center of the lower surface of the tray 10, the structure is simple and the cost can be kept low. . Similarly, the fixed rail 15 is also formed by a square pipe or the like and fixed to the lower surface of the tray 10, so that the cost can be kept low with a simple structure. Further, a locking recess 14 provided with the locking device 16 on either the rotating rail 13 or the tray 10,
Since it is provided on either of the other sides and is configured by the locking projection 17 that can be elastically engaged with the locking recess 14, the cost can be kept low with a simple structure. Further, the tray feeding device 31 is paired with the pair of rotating rollers 32, 32, 33, 3 which are in pressure contact with both sides of the rotating rail 13 of the tray 10.
3 and at least one rotating roller 32, 32 on one side thereof
Since it is configured by the drive motor 35 that rotationally drives, the tray delivery device 31 can be configured with a small number of parts, and the cost can be reduced. Further, the rotating rail 13 of the tray 10 is connected to the pair of rotating rollers 3
Since it is sandwiched between 2, 32, 33 and 33 and is fed out by one drive of the drive motor 35, the tray 10 can be fed out efficiently. Further, since the turning rail direction changing device 36 is composed of the rotating table 37 that supports the tray feeding device 31 and the motor cylinder 38 that rotationally drives the rotating table 37, the number of rotating rail direction changing devices 36 is small. It can be configured with the number of parts,
The cost can be reduced. Further, since the turning rail 13 of the tray 10 is clamped by the tray feeding device 31, the turning rail 13 of the tray 10 is directed vertically or horizontally on a horizontal plane by one drive of the motor cylinder 38. The direction change of 10 can be performed efficiently. Further, spherical rollers 11 are arranged at substantially four corners of the lower surface of the tray 10, and the tray moving rail 20 includes a pair of vertical rails 21 and a pair of horizontal rails 22.
Since it is configured with the corner rails 23, the tray 10
The moving path can be formed with a smaller number of parts than the conventional one. In addition, a corner rail 23 is provided at an intersection of each vertical rail 21 and each horizontal rail 22, and each spherical roller 11 of the tray 10 is vertically or laterally provided by the groove of the substantially cross shape or the T shape. Since the tray 10 is moved and guided, the tray 10 can be guided more reliably in the vertical direction or the horizontal direction and sent out.

In the above embodiment, the plane circulation type parking device to which the tray feeding mechanism 1 is applied is exemplified.
The tray feeding mechanism 1 is not limited to use in a plane circulation type parking device, but is used in various types of mechanical parking devices such as a horizontal circulation type, a plane reciprocating type, an elevator slide type, an elevator type, or the like. It can be appropriately installed at a place where circulation is required, and the same effects as the above can be obtained in various mechanical parking devices.
Further, the tray feeding mechanism can be similarly used in various automatic warehouses for storing various articles.
