Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mechanical multilevel parking system that can park a large number of cars.

(Prior Art) Conventional general mechanical multi-level parking systems include the vertical multi-level parking system 2 (■-type, here a double building is shown) shown in FIGS. 9 and 10, and the vertical multi-story parking system 2 shown in FIGS. There is a horizontal multi-level parking device 3 (H-shaped, the minus ridge is shown here) shown in FIG. 12. Both have lifting spaces 11 and 13 in the center, and in the vertical type 2, the pallet 15 is horizontally moved in the longitudinal direction of the car X from the elevator 11a to the car storage space 12 on each floor, while in the horizontal type 3, the elevator 13a From there, the pallet 15 is horizontally moved in the left-right direction of the car X and carried into the car storage space 14 on each floor.

(Problems to be Solved by the Invention) In both the vertical and horizontal types of the above-mentioned conventional mechanical multilevel parking systems, a lifting space 11.13 is provided in the center, and within this lifting space 11.13, car
I can't park my car.

In addition, in the case of the vertical type 2, in order for the car X to enter the elevator lla, an entry space 12a (Fig. 1O) for the car X is required in the direction of the entrance of the elevating space 11, and this area is also This means that car X cannot be parked. Therefore, for example, in the case of a four-story building, 7 cars can be parked in one building in vertical type 2, and 8 cars can be parked in one building in horizontal type 3. However, it is not possible to park within the lift spaces 11 and 13, which are equivalent to four cars. This condition is also the same in the case of a so-called multi-building type parking system in which a plurality of vertical or horizontal multi-story parking systems are arranged in series. Therefore, even if the multi-building type is used, the number of cars parked will only increase by a multiple of the number of parking cars in a single building type, and the parking efficiency per unit area will not be improved.

(Object of the Invention) This invention has been made in view of the above-mentioned points, and it is possible to park a car even in the space for raising and lowering the car of the mechanical multilevel parking system described above. It is an object of the present invention to provide a mechanical multi-level parking system that can park a larger number of cars in a smaller occupied area than multi-level parking systems.

(Means for Solving the Problems) The gist of the mechanical multilevel parking system of the present invention for achieving the above-mentioned purpose is to mount a car on a movable pallet and move the pallet up and down. In a mechanical multi-level parking system in which cars are stored by horizontally moving the pallets together in a car storage space, a pair of basic units with car storage spaces are installed on the left and right sides of a lift space in which the pallets are raised and lowered. At least the four corners of the left and right lifting spaces are equipped with circulation chains that circulate in the vertical direction, and the circulation chains between the left and right lifting spaces are common, and the opposing circulation chains are An engagement member capable of engaging with the pallet is arranged in correspondence with the vertical spacing of the storage space, and the engagement member is arranged to be engaged with the pallet, and between the top floors of the left and right lifting spaces and between the top floors of at least one of the left and right storage spaces on the front side or the rear side. In addition, a mechanism for moving the pallets left and right is provided, so that the left and right lifting spaces can also be used as a storage space for automobiles, except for the space necessary for the circulation operation.

(Function) According to the mechanical three-dimensional parking device of the present invention, the left and right lifting spaces and the top floors of the front and rear left and right storage spaces,
It is used as a space for circulating pallets when vehicles are taken out or put into storage. In order to take out a car parked in the garage in the storage space, one of the several pallets in the lift space is pulled into one of the top floors of the front or rear storage space and then moved into the lift space. By creating an empty space, sending the pallet of cars scheduled to leave from the garage in the storage space into the empty space, and sequentially performing a circulation operation, it is possible to leave the car from the lowest floor of the elevating space. In addition, when parking a car in a parking device, an empty pallet is placed on standby at the bottom floor of the lifting space, and the car is loaded onto the empty pallet.
By sequentially performing the circulation operation, the pallets in the storage space can be carried into an empty garage where the pallets are not stored. Furthermore, according to the multilevel parking apparatus of the present invention, for convenience of circulation operation for entering and exiting cars, the bottom floor 5 on the descending side and the top floor on the ascending side in the left and right elevating spaces 6, as well as in front of the elevating space or The two top floor storage spaces on the left and right rear must be left open, but cars can be parked in other spaces.

(Example) Hereinafter, an example of a four-story mechanical multilevel parking system of the present invention will be described based on FIGS. 1 to 8.

As shown in the plan view in FIG. 1, the basic unit 1' has a structure in which a lift space 6 for the car X is located in the center, and storage spaces 7°8 for the car A pair are arranged side by side adjacent to each other on the left and right. Each floor within the storage space 7.8 is configured as a garage 7a, 8a for parking the car X.
On a is a pallet 1 on which the car X is placed and moved.
5 is stored. Further, the lowest floor 4 of the left and right storage spaces 7 on the front side is left open as a passageway for the automobile X to enter and exit.

In at least the four corners of the left and right lifting spaces 6, endless circulation chains 20 and 21 are installed, passing through the upper and lower sprockets 20a, 21a and 20b, 21b, so as to be rotatable in the vertical direction. As shown in FIGS. 4 and 6, the circulation chain 21 between the left and right lifting spaces 6 is shared, so that each side of the circulation chain 21 can be used.

At the relative positions of the front and rear circulation chains 20.21, there are provided engaging members for the automobile loading pallet 15, corresponding to the vertical spacing of one floor of the storage space 7.8 (garages 7a, 8a). Pallet rails 18 and 19 are arranged across the rack. The pallet rails 18 and 19 are formed vertically symmetrically so that they can be used as pallet rails even when reversed.

Therefore, among the three rows of circulation chains 20, 21 on the left and right, the center circulation chain 21 is commonly used for the lifting spaces 6 on both sides. In addition, since only one side of the pallet rail 18 disposed on the outer circulation chain 20 of the three rows of circulation chains 20, 21 is used, it can be made only on one side without being vertically symmetrical.

With the above configuration, the circulation chains 20, 21 in the left and right lifting spaces 6 are rotated in common and synchronously with the circulation chains 21, so that the rotation directions thereof are opposite to each other.

Further, when the pallet rails 18 and 19 rise and reach the top dead center, they turn around the upper sprockets 20a and 21a and are turned upside down and lowered. This operating mode is the same even at bottom dead center.

The bottom floor 5 of the left and right lifting spaces 6 is equipped with a pallet 15.
pallets 15 are connected so that they can be moved mutually.
A conveyor 16 for left and right movement is provided as a moving mechanism.

Further, the top floors 9 of the left and right storage spaces 8 on the rear side are also communicated so that the pallets 15 can be moved mutually, and a traverser 17 for left and right movement as a movement mechanism for the pallets 15 is provided respectively. There is. Note that the structure for mutually moving the pallets 15 as described above may be provided on the top floor of the front storage space 7.

In addition, each garage in the front and rear storage spaces 7.8 has a 5th
As shown in the figure, a circulation chain 20 in the lifting space 6
．． The pallet 15 can be delivered onto the pallet rail 18.19 of the circulation chain 20.21, or vice versa, the pallet 15 can be delivered from the pallet rail 18.19 of the circulation chain 20.21 to the garage 7.
a, a longitudinal movement mechanism 10 for pulling into 8a;
is in place.

Then, when the pallet 15 on the descending side in the right or left lifting space 6 descends to the lowest floor 5, the pallet 15 is placed on the conveyor 16 just before the valet rail 18, 19 reaches the bottom dead center. Then, the pallet rails 18 and 19 are separated from the lower surface of the pallet 15, and the engagement is released.

In this way, the pallet 15 placed on the conveyor 16 is moved by the conveyor 16 to the lowest floor 5 of the separately measured elevating space 6.
It can be moved horizontally to The pallet 15 that has thus moved to the lowest floor 5 of the remote elevation space 6 engages with the pallet rails 18 and 19 on the ascending side and
rise within.

When the pallet 15 rises to the top floor of the lifting space 6, it is placed on the pallet rail 18. The pallet 15 is pulled in. After the pallet 15 on the traverser 17 is horizontally moved to the top floor 9 of the remote storage space 8, it is sent out onto the pallet rails 18, 19 in the lifting space 6 by the longitudinal movement mechanism 10 (Fig. 5). and is lowered in the lifting space 6 by means of a circulation chain 20.21.

In this way, the pallets 15 are raised and lowered within the lifting space 6 by the circulation chain 20.21, so that the lifting is stopped midway through and the pallets 15 in the front and rear storage spaces 7.8 are not stored. vacant garage 7a
, 8a (when parking a car), the pallet 15 can be pulled in by the moving mechanism 10 (FIG. 5). In addition, the pallet 15 can be delivered from the garages 7a and 8a in the storage space 7°8 onto the pallet rail 18.19 of the circulation chain 20.21 in the lifting space 6 by the moving mechanism 10 (Fig. 5). (at the time of issue).

To explain in detail again, the garage 7a has storage space 7.8.

In order to take out the car
A garage 7a with storage space 7.8 is created in the empty space.

The automobile X to be left from the warehouse is sent out along with the pallet 15 from 8a, and the vehicle is sequentially circulated and left from the lowest floor 5. In addition, when the car The pallet 15 in the storage space 7.8 is carried into an empty garage where it is not stored.

Therefore, it is possible to immediately enter the warehouse immediately after leaving the warehouse. Furthermore, if the pallets 15 in the lifting space 6 are empty, they can be stocked one after another.

By the way, in the multi-story parking device l of the present invention, for convenience of circulation operation for entering and exiting the car X, the lowest floor 5 on the descending side and the top floor on the ascending side in the left and right elevating spaces 6 must be left open. Must be. In addition, two locations on the top floor 9 of the left and right storage spaces 8 on the rear side must also be left open.

In other words, the left and right lifting spaces 6 and the top floor 9 of the left and right storage spaces 8 on the rear side are used as spaces for circulation operation of pallets 15 (shaded areas) as shown in FIG. ) used as Therefore, a total of 18 cars can be parked in the multi-story parking system 1, and 18 pallets 15 corresponding to this number of cars can be parked in the garages 7a and 8a in the storage space 7.8. It is pre-arranged on pallet rails 18, 19 in the lifting space 6. Note that a car can also be parked on one side of the lowest floor 4 of the front storage space 7, so in the case of this embodiment (four-story building), a total of 19 cars can be parked.

Further, a drive mechanism 22 that circulates the circulation chinos 20 and 21 in opposite directions in the left and right lifting spaces 6 is shown in FIGS. 6 and 7. According to this drive mechanism 22, one motor 23 By means of the drive chain and the driven sprocket 24, the circulation chain 20.21 can be rotated synchronously and counterclockwise.

Next, a specific example of the exit operation for the multi-level parking apparatus l of the above embodiment will be explained based on FIG.
When the car X marked with the mark is to be taken out of the warehouse, the pallet 15 on the top floor of the lifting space 6 is pulled into one of the top floors 9 of the rear storage space 8 and the circulation chain 20 is pulled in as shown in FIG.
．． 21, the empty pallet rails 18 and 19 of circulation chain 20.21 are moved to the garage of car 15 onto the empty pallet rails 18 and 19 in the lifting space 6. And the same figure (
The pallet 15 is moved to the lowest floor 5 by repeating the circulation operation as shown in d) and (e).

In this way, as shown in FIG. 5(f), the car X marked with ◎ can be taken out of the garage.

(Effects of the Invention) According to the mechanical multilevel parking system of the present invention having the above-described configuration, the following effects are achieved.

In the conventional mechanical multilevel parking system described above, the elevator
Not a single car could be parked in the space, so in the case of a four-story double-level parking system, eight spaces were wasted. - On the other hand, in the present invention, the entire parking device 1 is used as a circulation space for the circulation operation of pallets.
Although a space for one car is required, since cars can also be parked within the lift space, the number of cars parked can be greatly increased compared to conventional parking devices. In addition, the space required for circulation operation remains constant even if the number of floors of the parking device increases (4
Therefore, the more the number of floors is increased, the more the occupancy rate of one white space for a car decreases and the more the parking efficiency per unit area is improved compared to conventional parking devices.
