[0025]
Next, the entering / exiting operation | movement of the motor vehicle c is demonstrated.
First, at the time of warehousing, the wheeled carriage 10 on which the tray 4 in the parking space 2 of the level to be parked is placed is traversed on the rail 9 and sent out onto the hoistway 1 (see FIG. 6). In this case, the claw portion 3 b of the lift 3 is previously positioned below the tray 4 on the carriage 10.
[0026]
Therefore, the lift 3 is raised, and only the tray 4 is supported by the claw portion 3b of the lifting rod 3a of the lift 3, and the lift 3 is slightly raised and stopped. Next, the carriage 10 is returned to the original parking space 2, and the lift 3 stops when the tray 4 moves up and down to the level of the boarding portion. In this state, it is waiting for storage, and the movable step 23 is also at the same level.
[0027]
When a required tray 4 is called by an operation panel (not shown) provided in the vicinity of the entrance / exit door 27, if the tray 4 is in a waiting state for entry as described above, the entry / exit door 27 is opened. c can get into the tray 4 of the boarding section.
[0028]

Next, when the carriage 10 is traversed to the hoistway 1 and the lift 3 is lowered there, the tray 4 is delivered to the carriage 10. Next, when the carriage 10 is traversed to the original parking space 2, the warehousing is completed.
[0029]
When parking in the parking space 2 below the boarding part, the cart 10 of the level to be parked in advance is moved from the parking space 2 to the hoistway 1 and the tray 4 on which the automobile c is placed is supported by the lift 3. When the tray 4 is lowered below the carriage 10 in the hoistway 1, the tray 4 is transferred to the carriage 10, so that it moves to the parking space 2 and stops.
[0030]
When leaving, the movement from traversing the parking space 2 above the boarding part to the hoistway 1 to the hoistway 1 and placing it on the lift 3 is the reverse of the above, but the lift 3 goes to the boarding part. While lowering, the arm driving device 15 is operated to cause the tray support arm 14 to protrude into the hoistway 1 and when the lift 3 is lowered below the loading portion, the protrusion 4a of the tray support arm 14 is formed in the recess 4a of the tray 4. The tray 4 and the left and right table members 13a are integrated to form the turntable 13. Therefore, after operating the stopper device 16 to release the engaging rod 16a from the engaging hole 13b of the table member 13a and operating the link driving device 26 to retract the movable step 23 from the turning area of the turntable 13, the two The turning motor 20 is simultaneously driven to rotate the tray 4 180 degrees, and further, the movable step 23 is raised to the loading section level to open the entrance / exit door 28, and the automobile c is delivered forward.
[0031]
In addition, when making it take out from the hierarchy below a boarding part, the lift 3 which loaded the motor vehicle c is lifted a little upwards from a boarding part. Subsequent operations are the same as described above.
[0032]
FIG. 8 is a plan view of a boarding unit according to another embodiment, and only a portion different in operation from the above will be described.
In FIG. 8, the tray 4 is supported and engaged with a tray support arm 14 protruding from the hoistway 1 to form a turntable 13 integrally with the left and right table members 13a. At the time of warehousing, the movable step 23 is lifted by the link driving device 26 to the same level as the boarding portion. Therefore, the entry / exit door 28 is opened and the automobile c is loaded. Next, when the stopper device 16 is operated to disengage the engagement rod 16a from the engagement hole 13b of the table member 13a, and the pinion 21 is rotated by driving the turning motor 20, the side surface of the table member 13a is moved. The turntable 13 is turned 90 degrees while engaging with the rack 22 provided along the track.
[0033]
Therefore, if the lift 3 that has been kept waiting below the boarding portion is raised, the tray 4 can be supported as it is and moved to the upper parking space 2 for parking. In order to move to the parking space below the boarding portion, the tray 4 is picked up by the lift 3 slightly above the boarding portion, and then the tray support arm 14 is retracted from the hoistway 1 by the arm driving device 15 and lifted. If 3 is lowered, it can move to an arbitrary level and park.
[0034]
Since the exit operation is the reverse of the above, a detailed description is omitted, but after returning the exiting tray 4 to the loading section, the turntable 13 is further rotated 90 degrees in the same direction as when the turntable 13 was rotated, The movable step 23 is lifted to the same level as the loading section, and the loading / unloading door 27 is opened and the cargo is moved forward.
[0035]
The above-described embodiments have described the turntable turning device attached to the elevator type parking device provided with multiple parking spaces on both sides of the lift hoistway, but of course not limited to this, for example, The present invention can also be applied to a circulation type parking apparatus having a large number of parking spaces on the side of the lift as described in Japanese Patent Laid-Open No. 1-17975.
