Therefore, the elevating frame 7 moves about ±50 mm in the directions of arrows C and D in FIG. Slide to a certain degree.

Next, in the device of the present invention having the above configuration,
For example, in order to improve the driver's driving safety and parking efficiency by having the automobile 2 enter the warehouse in the forward direction and exit the warehouse in the forward direction, the turning tray 4 on which the automobile is placed is rotated by 180 degrees ( It is preferable to rotate the storage cage 4 (or 90 degrees) by pressing an appropriate call button (not shown) to drive and circulate the storage cage 4 to the car loading/unloading position, that is, the cage's lowest position, and then stop the storage cage 4. When the vehicle 2 is placed on the revolving tray 4 of the storage cage and left, a sensor (not shown) is activated to drive the geared motor 58 of the slide mechanism 9, thereby moving the elevating frame 7 to the position shown in FIG. The light emitting and receiving photoelectric sensor 29 built into the center post 26 of the elevator platform receives a reflected light beam from the sensor mirror 30 provided at the center of the back surface of the rotating tray. When the rotation drive member 5 is caught, the slide mechanism is stopped, and in order to complete the centering of the rotation tray and the rotation drive frame 18 of the tray rotation drive member 5, the rotation drive frame is inserted into the fitting groove of the rotation tray. 17, and can be fitted smoothly without becoming an obstacle.

Next, in FIGS. 1 and 2, in the case of a front entry type parking device, when the drive motor 42 of the power cylinder unit 37 is rotated in the forward direction,
The cylinder rod 45 is pulled inward, causing the bell crank 38 and crank lever 41 to rotate in the direction of the hour hand.At the same time, the crank levers 39 and 41, which are connected via the connecting rod 56, also rotate in the direction of the hour hand. The elevating frame 7 or the overhang member 51, which was supported at the solid line position by the push-up rollers 48 and 50 attached to these crank levers, rises to the two-dot chain line position (with a maximum stroke of 280 mm).
mm), as the tray rotation drive member 5 also rises, the rotation drive frame 18 of the drive member fits into the fitting groove 17 of the rotation tray 4, which has been centered in advance, and lifts the tray. The pivoting tray is disengaged from the cage member 3 of the storage cage 1 and is in the 4' position. When this state occurs, if the drive motor 42 of the power cylinder unit 37 is stopped and the pole change motor 21 of the tray rotation drive mechanism 6 is activated, the tray rotation is driven via the worm reducer 22 and the differential gear pair 23. The drive pinion 24 that meshes with the ring gear 19 of the member 5 rotates, whereby the swing drive frame 18 integrally formed with the ring gear via the circular rail 16 moves in the direction of arrow A shown in FIG. Rotate 180°. Therefore, if the pole change motor 21 is stopped at this position and the drive motor 42 of the power cylinder unit 37 is reversely rotated, the rotating tray 4 will move as shown in FIG.
The elevating frame 7 or the elevating frame 51 lands on the cage member 3 of the storage cage 1 in a movement course opposite to the upward movement of the overhanging member 51 as described above, and the elevating member or the elevating frame moves from the two-dot chain line position to the solid line position. Then, after the drive motor is stopped, the cars on the storage cage are circulated and stored at a predetermined position.

On the other hand, when leaving the warehouse, press the operation button to call the storage cage 1 to the car unloading position in the same way as when entering the warehouse.
Since it is oriented in the B' direction, the incoming vehicle can exit in the forward direction.

Next, in order to take the car 2 out of the parking lot in the case of the side entry type parking device, the same operation as in the case of the parking device of the front entry type described above is carried out to take the car 2 into the parking lot that has been stored in the storage cage 1 in advance. The vehicle is called to the automatic unloading position, and the rotating tray 4 is raised by the gantry lifting mechanism 8 to be detached from the cage member 3 of the storage cage 1, and then rotated by 90 degrees by the tray rotating drive mechanism 6, and then the rotating tray is Some (20
mm), and as shown in Fig. 3, the rotating tray 4' is temporarily landed on the walking platform 63 in the direction of the arrow B' by the receiving rollers 64 arranged opposite to each other, and in this state, the incoming car is Unload the vehicle in the forward direction. Next, the rotating tray 4' is slightly raised as before, and at the same time, the tray rotating drive mechanism 6
The process is completed by reversely rotating 90 degrees and placing the rotating tray 4 on the cage member 3 of the storage cage 1 using the gantry lifting mechanism 8.

As described above, according to the present invention, the following effects are achieved.

(1) In the conventional device, the circular rail of the turntable, the main roller group that fits into the circular rail, the center post, etc. are all installed on the storage cage side, whereas in the device of the present invention, the tray The swing drive frame, circular rail, center post, etc. that form the swing drive member are all installed on the pit or floor side, and can perform three types of movements such as raising and lowering the elevating frame, sliding the swing drive frame, and rotating the tray. Since this is carried out continuously and the load is mainly received over the entire cage hanging side, it is possible to reduce the weight of the cage by reducing the installation height of the cage, increase the number of cages accommodated, and reduce costs.

(2) When the storage cage lands on the floor, until the light emitting/receiving photoelectric sensor on the center post detects the reflected light beam from the sensor mirror on the back of the rotating tray.
The slide mechanism centers the rotating tray and the rotating drive frame to enable reliable rotation of the rotating tray, thereby ensuring speedy loading and unloading of automobiles and safe operation of the device.

(3) After a car is put into the storage cage in the forward direction for storage, the revolving tray can be rotated 90° or 180° and the car can be taken out by forward movement, so the driver can drive the car with peace of mind. Therefore, it is safe, and since it is not necessary to provide a turntable in front of the parking device or to take up a vacant space for changing the direction of the car, it is economical because the effective use of land is improved.
