Description: TECHNICAL FIELD The present invention relates to a multilevel parking apparatus for parking a large number of vehicles in a small area.

[Conventional technology]

Conventionally, as a device for storing a large number of vehicles in three dimensions, there is one disclosed in Japanese Patent Laid-Open No. 59-21869.

This known device is provided with a multi-layered building consisting of a first-floor part on which a car can be directly placed and a second-fifth-floor part consisting of two multi-tiered storage shelves placed opposite to each other at predetermined intervals. , The yagura arranged in the space between the multi-tiered storage shelves on the second to fifth floors are provided so as to move horizontally on the rails laid along the respective front faces of the multi-tiered storage shelves, and also moved up and down in the yagura. A platform is provided, and rails on which a trolley for mounting an automobile is mounted are provided on each of the storage units and the elevators arranged on the left and right of the multi-stage storage rack.

When entering the warehouse, first move the yagura to the front of the empty storage compartment, raise and lower the elevator to a position facing the storage compartment and stop it, and then pull out the trolley in the storage compartment by operating the moving platform and the gripping arm to raise and lower the platform. After being transferred and held upward, the yagura is moved above the mounting portion, and then the elevating table is lowered into the mounting portion to stand by.

Then, the vehicle is made to enter the trolley from the entrance / exit via the bridge deck, and the driver is alighted in this state.

Next, the elevating platform is raised to the original storage unit height, the yagura is horizontally moved to the front of the storage unit, and then the carriage with the automobile mounted is pushed out and stored in the storage unit by guiding the moving platform.

[Problems to be Solved by the Invention]

On the 1st floor where the car can be placed directly, the 2nd to 5th floors consisting of two multi-tiered storage shelves are installed opposite each other with a predetermined space between them. Since it is provided, there is a problem that the number of automobiles stored in the yagura space is significantly reduced and the land cannot be effectively used.

In addition, since the elevator that moves up and down inside the room is lowered into the recessed mounting part on the first floor to take in and out the storage position, only the mounting part can be used for loading and unloading. There was also a problem that it was not possible to leave the goods directly on the first floor.

Therefore, according to the present invention, the vehicle can be put in and out from each of the direct placing portions on the first floor, and the vehicle of the direct placing portion can be retracted to the side direct placing portion or the side direct placing portion to an empty storage portion above. It is an object of the present invention to provide a multi-level parking apparatus that allows a vehicle at any position to freely leave a storage section through a direct placement section and can be stored at any position by operating in the opposite manner.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a frame-shaped lifting floor arranged in parallel in a lateral direction at right angles to a large number of loading and unloading directions, each having a drive device for hoisting and hanging,
A pit provided on the ground to accommodate the lowered floor, a traverse device provided in the pit so that the transport surface is located at a position higher than the elevator floor accommodated in the pit, and at least the total number of vehicles to be stored. It consists of a pallet that overlaps the lifting floor with a small number of two and rides on the horizontal transfer device, and an engagement device that is provided so that it can be engaged and disengaged with the pallet on the lifting floor that has been raised to the storage position due to operation. It is a thing.

[Action]

When storing a vehicle, first the pallet on the horizontal transfer device of the storage structure having the lifting floor to be actuated is evacuated to the side by the drive of the required horizontal transfer device, and the lifting floor that has been lowered to the pit beforehand is lifted. The retracted pallet is received on the ascending / descending floor and retracted upward.

Then, the lifting floor is lowered into the pit and one or more pallets stacked on the lifting floor are received on the horizontal transfer device.

Then, after loading the vehicle on the top pallet of one or more stacked pallets from the ground, and raising the lifting floor by the drive device, the vehicle also rises together with the stacked pallets, and the loading pallet of the vehicle After ascending to a predetermined position, the engaging device is operated to engage the pallet to support the vehicle loading pallet at a fixed position.

After that, when there is only one pallet, only the lifting floor, and when two pallets are stacked, the lower pallet is lowered along with the lifting floor while being received on the horizontal transfer device, and then the vehicle is loaded. The lower pallet lifted by the same method as described above is supported via the engaging device.

On the empty horizontal transfer device, the pallet on the adjacent horizontal transfer device is returned, and the vehicle is loaded on the returned pallet.

The vehicle is stored in the storage structure of each row by the above method.

When unloading, the vehicles on the pallet at the bottom are left as they are without moving the pallet. Next, when unloading the second-tier vehicle from the bottom, the pallet on the lateral transfer device is retracted in the side direction.

After that, the pallet in the middle stage, which is supported by raising the lift floor a little, is pushed up, and after the support of the pallet is released by the engagement device, the pallet on which the vehicle is loaded is lowered along with the lift floor, and the pallet is moved on the horizontal transfer device. It is received and the vehicle is unloaded from the pallet.

Also, when the middle pallet is empty, the empty pallet is raised together with the lifting floor when the middle pallet is empty, and the upper surface of the lower pallet is overlapped with the upper surface of the lower pallet. Raise the upper pallet a little.

After that, the support of the upper pallet by the engaging device is released, the pallet is received on the horizontal transfer device while lowering the overlapping pallet together with the lifting floor, and the vehicle is discharged from the pallet.

If the vehicle on the upper pallet above the middle pallet where the vehicle is present is to be unloaded, first evacuate the bottom pallet by the horizontal transfer device, and then lower the middle pallet together with the vehicle and place it on the horizontal transfer device. At the same time, the pallet on the moving device that has moved to the evacuation area at the end is lifted to the evacuation area in the upper space and retracted.

Next, the pallet on the transfer device is laterally moved and retracted again, and then the upper pallet to be unloaded is lowered onto the horizontal transfer device and the vehicle is unloaded.

By repeating the above, as shown in FIG. 18, the vehicle is stored in the storage frame 3 except the leftmost storage frame 3.

The method of loading is not limited to the above, but since the number of pallets is two or less than the total number of vehicles stored, two or more vehicles can be loaded from any position. Can be stored at the same time.

When the vehicle is to be unloaded, the pallet 11 on the horizontal transfer device 9 which is directly placed on the ground is directly discharged from the pallet 11 and the vehicle stored immediately above the empty pallet on the horizontal transfer device 9 first.
11 is laterally fed, and the lower pallet 11 is lowered together with the lifting floor 1 onto the horizontal transfer device 9 to be discharged, and then the empty lower pallet 11 is raised together with the lifting floor 1 to be placed on the lower pallet 11 above. Overlay the upper pallet 11 and the engaging device
The engagement by 12 is released and the vehicle is lowered together with the upper and lower pallets 11 while being received on the lateral transfer device 9 and then taken out, and further, the vehicle on the lower pallet 11 of the storage structure 3 or When the vehicle on the upper pallet 11 is to be unloaded, the vehicle on the lateral transfer device 9 is laterally fed together with the pallet 11 and the vehicle is moved up and down with the pallet 11 transferred onto the lateral transfer device 9 of the storage structure 3 at the right end 1 The vehicle is transferred together with the pallet 11 onto the empty lateral transfer device 9 at the right end.

After that, the vehicle is lowered along with the lower pallet 11 onto the empty horizontal transfer device 9 via the lifting floor 1 to leave the vehicle, and when the vehicle on the lower pallet 11 is not to be output, the pallet 11 on the horizontal transfer device 9 is removed. Then, the vehicle is lowered along with the upper pallet 11 through the elevator floor 1 on the empty horizontal transfer device, and then the vehicle is discharged.

If the total number of pallets 11 is less than the total number of vehicles in the storage structure 3 by three or more, the delivery time can be shortened.

It should be noted that stop positioning of the pallet 11 which is fed laterally by the lateral transfer device 9 is performed using a limit switch or the like.

〔effect〕

As described above, according to the three-dimensional parking apparatus according to the present invention,
Only a vehicle on the lower pallet or a vehicle on the upper pallet can be smoothly delivered by combining the lifting floor and the horizontal transfer device on the ground.

For this reason, it is not necessary to evacuate the vehicle on the lower pallet to the ground first, and to unload the vehicle on the upper pallet.

Since the number of pallets is at least two less than the total number of vehicles stored, two or more pallets can be loaded and unloaded simultaneously from any position without unloading other vehicles.

Therefore, it is possible to remarkably shorten the loading / unloading time.
