Further, the turning device 34 horizontally turns the horizontal moving table 16 with the vehicle placed at a loading / unloading port (for example, the first floor) (not shown) where the vehicle enters and leaves, thereby enabling the vehicle to enter the front and the front. Yes.
In the present invention, the jack-up mechanism 32 and the turning device 34 are not indispensable and can be omitted.

  FIG. 3 is an operation explanatory diagram when the mechanical parking device of FIG. 1 is stored. In this figure, according to the control method of the present invention, when the vehicle is stored in the storage shelf 20, the lifting carriage 10 is operated in the order of (A), (B), (C), and (D) in FIG.

  First, as shown in FIG. 3A, when the vehicle 1 is transferred from the lifting cart 10 to the storage shelf 20, the horizontal movement table 16 is stopped at a position higher than the corresponding storage shelf 20. This height is set to a height at which the cart fork unit 15 and the shelf fork unit 22 do not interfere with each other due to the horizontal movement of the horizontal moving table 16.

  Next, as shown in FIG. 3B, at this position, the horizontal moving table 16 is moved up into the storage shelf by the horizontal moving device 18. This traversing position is set to a horizontal position where the cart fork unit 15 and the shelf fork unit 22 do not interfere with each other by raising and lowering the horizontal moving table 16.

  Next, as shown in FIG. 3C, the horizontal moving table 16 is lowered and the vehicle 1 is placed on the shelf fork portion 22. This lowering may be performed by either the lifting carriage 10 or the jackup mechanism 32, or both may be used in combination.

  Next, as shown in FIG. 3 (D), the horizontal moving table 16 is moved up to the inside of the elevating carriage 10 and the warehousing operation to the storage shelf 20 is completed.

  FIG. 4 is an operation explanatory diagram of the mechanical parking device of FIG. 1 when leaving. In this figure, according to the control method of the present invention, when the vehicle is unloaded from the storage shelf 20, the lifting carriage 10 is operated in the order of (A), (B), (C), and (D) in FIG.

  First, as illustrated in FIG. 4A, when the vehicle 1 is transferred from the storage shelf 20 to the lift cart 10, the horizontal movement table 16 is stopped at a position lower than the corresponding storage shelf 20. This height is set to a height at which the cart fork unit 15 and the shelf fork unit 22 do not interfere with each other due to the horizontal movement of the horizontal moving table 16.

  Next, as shown in FIG. 4B, at this position, the horizontal moving table 16 is moved up into the storage shelf by the horizontal moving device 18. This traversing position is set to a horizontal position where the cart fork unit 15 and the shelf fork unit 22 do not interfere with each other by raising and lowering the horizontal moving table 16.

  Next, as shown in FIG. 4C, the horizontal moving table 16 is raised correspondingly, and the vehicle 1 is placed on the cart fork unit 15. This rise may be caused by either the lifting carriage 10 or the jack-up mechanism 32, or both may be used in combination.

  Next, as shown in FIG. 4 (D), the horizontal moving table 16 is moved to the inside of the lifting cart 10 to complete the warehousing operation from the storage shelf 20.

Further, when the lifting carriage 10 has a jack-up mechanism 32 that moves the horizontal moving table 16 up and down,
(A) When the vehicle 1 is transferred from the lifting cart 10 to the storage shelf 20, the lifting cart 10 is stopped at a position higher than the corresponding storage shelf 20 by the horizontal moving table 16, and at this position, the jackup mechanism 32 Lower the moving table 16,
(B) When the vehicle 1 is transferred from the storage shelf 20 to the lifting cart 10, the lifting cart 10 is stopped at a position lower than the corresponding storage shelf 20 by the horizontal moving table 16, and the jack-up mechanism 32 horizontally The movable table 16 may be raised.

  By this method, the lifting carriage 10 can be stopped and the storage rack 20 can be loaded and unloaded, and the rail 11 (in this example, H-shaped steel) is fixed to the gantry and has a falling moment that acts on the lifting carriage 10 and extends vertically. Therefore, the cage 12 can be held stably and horizontally.

  According to the apparatus and method of the present invention described above, the storage shelf 20 has the comb-shaped shelf fork portion 22 that is fixed to the outside in the longitudinal direction of the vehicle and supports the front and rear wheels 3 of the vehicle. Since the comb fork-shaped carriage fork portion 15 that supports the front and rear wheels 3 of the vehicle at a position that is fixed on the inner side in the longitudinal direction of the vehicle and does not interfere with the shelf fork portion 22 on the horizontal plane, the shelf fork portion 22 is fixed. Thus, the vehicle fork unit 15 can be moved up and down to transfer the vehicle 1 between the shelf fork unit 22 and the vehicle fork unit 15.

  In addition, the lifting carriage 10 is located on the inner side in the longitudinal direction of the vehicle and supports the horizontal moving table 16 that supports the inner side in the longitudinal direction of the carriage fork portion 15. And the horizontal fork unit 15 is moved horizontally into the storage shelf 20, and the vehicle fork unit 15 is moved up and down to move the vehicle 1 between the shelf fork unit 22 and the truck fork unit 15. Then, the cart fork unit 15 can be horizontally moved back from the storage shelf onto the lift cart.

  Therefore, since the vehicle 1 can be traversed with respect to all the storage shelves 20 by one horizontal movement device 18 provided in the lifting carriage 10, a traversing mechanism for traversing the vehicle for each storage shelf is unnecessary. Even when the number of parked vehicles is large, the production cost occupied by the traversing mechanism can be reduced.

  In addition, this invention is not limited to embodiment mentioned above. That is, the scope of the present invention is indicated by the description of the scope of claims, and further includes meanings equivalent to the description of the scope of claims and all modifications within the scope.
