Then, when the empty pallet 8 is taken out from the right storage shelf 4 in FIG. 2, the turntable 10 is turned clockwise from the home position shown in FIG. 10 at a low position. Then, as the turntable 10 turns, the links 25 and 25a are linearly formed by the link device 15 as shown in FIG. 8, the arm 12 is seesaw, and the projection 12a of the arm 12 rises, which is indicated by a one-dot chain line in FIG. The protrusion 12a enters the groove 8b of the empty pallet 8 of the right storage shelf 6 at a high position. Then, the swivel plate 11 is swung as it is, and the empty pallet 8 is traversed on the cage 3. At this time, the protrusion 12b is lowered to a low position.
[0025]
Thereafter, the cage 3 is lowered in the cage hoistway 2 by the wire rope 28, and the endless chain 35 is rotated by rotating the rotating shaft 34 by the pallet elevating drive device 36 of the pallet elevating device 5 at the entrance / exit. By rotating the drive sprocket 33 and the driven sprocket 31, the ball screw 30 is rotated and the nut 32 is operated to raise the turntable 10, so that the upper surface of the swivel plate 11 of the turntable 10 contacts the lower surface of the pallet 8. Push up. Then, the turning drive device 41 of the pallet turning device 6 is driven to rotate the gear 40, the turning ring 37 is turned to turn the empty pallet 8 by 90 °, and then the turntable 10 is lowered again to return the empty pallet 8. Both ends of the vehicle are supported by a loading / unloading port and a support material (not shown) provided on the opposite side to prepare for loading of the automobile 13.
[0026]
When the automobile 46 enters, the automobile 46 is introduced into the building from the entrance and exit, and is stopped on the empty pallet 8 that has been placed on the turntable 10 and has been waiting in advance. After confirming that the driver leaves the automobile, the vehicle pallet 8 is turned in the same manner as described above to turn the vehicle 13 together with the vehicle pallet 8 by 90 °. Thereafter, the turntable 10 is lowered, the actual vehicle pallet 8 is placed on the pallet traversing frame 3b, and the cage 3 is lifted and lifted by a procedure opposite to that when the empty pallet 8 is pulled out from the storage shelf 4. Store in storage shelf 4.
[0027]
Next, the case where the entrance / exit is on the extension line in the longitudinal direction of the cage 3 will be described. In this case, by turning the turntable 10 by 180 ° at the time of entering or leaving, the vehicle 46 can be moved forward and forward.
[0028]
The present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
