As shown in FIG. 8, a storage elevator 3 for transferring a vehicle 2 received from a storage berth 1 on the ground to a required underground floor is provided, and a vehicle 2 for transferring the vehicle 2 received by the storage elevator 3 is provided. The mobile trolleys 4 are provided so as to be able to travel on each floor, and a plurality of vehicles 2 are provided on the right and left sides in the width direction of the traveling path 5 of the mobile trolleys 4 provided on each floor, respectively, on the near side and the rear side with respect to the mobile trolley 4 (Two in the example in the figure) A storage shelf 6 that can be stored in a side-by-side manner is provided, and a delivery elevator 8 for taking out the vehicle 2 stored in the storage shelf 6 from a delivery berth 7 is provided. There is something that I did.

[0003] On the movable carriage 4 and the storage shelf 6,
Conveyors 9 and 10 for directly transferring the vehicle 2 are provided. However, providing a driving device for each of the conveyors 10 provided on the large number of storage shelves 6 leads to an increase in cost. A driving device (not shown) is provided on the conveyor 9 provided on the upper side, and between the conveyor 9 provided on the movable carriage 4 and the conveyor 10 provided on the storage shelf 6 as necessary. A disconnector (not shown) using gears or friction wheels capable of connecting and disconnecting the two conveyors 9 and 10 is provided to transfer the vehicle 2 from the mobile trolley 4 to the storage shelf 6 at the time of entry. Alternatively, when the vehicle 2 is transferred from the storage shelf 6 to the movable trolley 4 at the time of unloading, the two conveyors 9 and 10 are used.
Is connected via the disconnector, the conveyer 9 on the storage shelf 6 can be driven synchronously by driving the conveyer 9 on the movable trolley 4 by the driving device. In addition, conveyors 11, 12, 13, and 14 for directly transferring the vehicle 2 are also provided in the storage berth 1, the storage elevator 3, the storage berth 7, and the storage elevator 8.

In the multi-story parking device shown in FIGS. 7 and 8, when the vehicle 2 is to be stored, the vehicle 2 gets on the storage berth 1 and is sent by the conveyor 11 to the conveyor 12 on the storage elevator 3 to remove the storage elevator 3. After lowering to the required floor and transferring the vehicle 2 from the conveyor 12 on the entrance elevator 3 to the conveyor 9 on the movable trolley 4,
The mobile trolley 4 is caused to travel along the traveling path 5 to a desired storage shelf 6 position, and the vehicle 2 is moved to the conveyor 9 on the mobile trolley 4.
From the storage shelf 6 to the conveyor 10 on the storage shelf 6.

When the vehicle 2 is to be taken out of the warehouse, the storage shelves 6
Is moved to the conveyor 9 on the movable trolley 4, the movable trolley 4 is moved along the traveling path 5 to the position of the exit elevator 8, and the vehicle 2 is moved to the conveyor 9 on the movable trolley 4. From 9, it is sent to the conveyor 14 on the exit elevator 8, the exit elevator 8 is raised to the ground, and the vehicle 2 is sent from the conveyor 14 on the exit elevator 8 to the conveyor 13 on the exit berth 7.

[0006]

However, in the conveyer-type multi-story parking device as described above, if a new vehicle 2 is to be stored in the storage shelf 6 in which the vehicle 2 is already stored on the near side, an emergency should be taken. In the case where the speed of the conveyor 10 on the storage shelves 6 is not synchronized with the speed of the conveyor 9 on the movable trolley 4 due to poor connection of the disconnector or the like, the speed of the conveyor 9 is short. There is a risk that the vehicle 2 that is about to be newly stored comes into contact with the vehicle 2 stored on the side, and both vehicles 2 are mutually damaged.

[0007] Also, when a new vehicle 2 is stored in the storage shelf 6 in which the vehicle 2 is not stored, as described above,
If the speed of the conveyor 10 on the storage shelf 6 is slower than the speed of the conveyor 9 on the moving trolley 4 without being synchronized, the wheels on one of the left and right sides of the vehicle 2 are moved to the conveyor on the moving trolley 4. 9 to the conveyor 10 on the storage shelf 6, the traversing speed of the wheels on one of the left and right sides of the vehicle 2 and the vehicle 2
A difference is generated between the traverse speeds of the left and right wheels on the other side, and unnecessary force acts on the vehicle 2 in a direction of bringing the right and left wheels closer to each other, which is not preferable. Was.

Furthermore, the vehicle 2 stored in the storage shelf 6
As described above, when the speed of the conveyor 10 on the storage shelf 6 is not synchronized with the speed of the conveyor 10 on the movable trolley 4 when the vehicle 2 is unloaded, the left and right sides of the vehicle 2 Is moved from the conveyor 10 on the storage shelf 6 to the conveyor 9 on the moving trolley 4, and the traversing speed of the left and right wheels of the vehicle 2 and the traversing of the other left and right wheels of the vehicle 2 A difference is generated between the vehicle speed and the vehicle speed, and an unnecessary force is applied to the vehicle 2 in a direction to separate the left and right wheels from each other, which is not preferable.

In the case of a conveyor-type multi-story parking device,
Since the vehicles 2 having various shapes and sizes are directly delivered, it is necessary to provide a large number of electric control parts such as various sensors on each storage shelf 6, which leads to an increase in cost and poor maintenance. I was

The drawbacks of the above-described conveyor-type multi-story parking device can be solved by adopting a pallet system in which a vehicle is placed on a pallet to perform loading and unloading, but a plurality of the pallets are provided on the near side and the back side. At present, a multi-story parking device having storage shelves that can be stored side by side has not been developed.

In view of such circumstances, the present invention allows a plurality of vehicles to be efficiently stored on the near side and the back side of the storage shelf without damaging or applying unnecessary force to the vehicles, and is advantageous in terms of cost. Another object of the present invention is to provide a multi-story parking device which is excellent in maintainability.

[0012]

According to the present invention, a plurality of pallets are arranged on at least one of the left and right sides in the width direction of a transfer device for transferring a pallet on which a vehicle is mounted. What is claimed is: 1. A multi-story parking device provided with a storage shelf that can be stored in a form to be installed, a swivel arm arranged so as to be horizontally turnable in the transfer device, and a guide attached to a lower surface of the pallet so as to extend in a longitudinal direction thereof.

And a supplementary transfer device capable of pulling the set pallet toward the front side.

[0013]

Therefore, when a vehicle loaded with a pallet on a transfer device is to be stored in a desired storage shelf, the vehicle must be engaged with the guide member of the pallet while the engaging member of the transfer device is engaged.
When the turning arm is horizontally turned in a required direction, the engaging member moves along the guide member of the pallet, and the pallet on the transfer device is pushed out to the front side of the storage shelf and stored.

When the vehicle is further stored in the storage shelf in which the pallet on which the vehicle is mounted is stored on the front side, the pallet on the transfer device is moved to the storage shelf side by the turning arm of the transfer device in the same manner as described above. Then, the pallet on the transfer device is placed on the near side of the storage shelf, and the pallet on the near side of the storage shelf is pushed into the back side.

At this time, if the driving mechanism is not connected to the power transmission mechanism of the auxiliary transfer device and the transfer mechanism is in a free state, the hook of the transfer mechanism is located on the near side of the storage shelf. The pallet is pushed to the back side while being engaged with the edge of the lower surface of the pallet.

On the other hand, when a retrieval request is issued to the vehicle stored in the back of the storage shelf, the pallet on the front side of the storage shelf is moved onto the transfer device by the turning arm of the transfer device. After being retracted, the transfer device is run, the pallet on which the vehicle is mounted on the transfer device is once transferred to another storage shelf, and the transfer device is returned to the storage shelf position where the delivery request was issued again.

When the transfer device is returned to the position of the storage shelf where the retrieval request has been issued, the drive mechanism of the auxiliary transfer device is slid by a required amount toward the power transmission mechanism, and the power is transmitted through the disconnector. When the drive mechanism is driven in a state where the drive mechanism is connected to the mechanism, the driving force of the drive mechanism is transmitted to the transfer mechanism via the breaker and the power transmission mechanism, and the hook of the transfer mechanism is retracted. The pallet is moved toward the transfer device while engaging with the lower edge of the pallet stored at the back of the shelf, and the pallet stored at the back of the storage shelf is drawn toward the front by the hook.

Thereafter, the pallet pulled toward the front side of the storage shelf is pulled into the transfer device by the turning arm of the transfer device in the same manner as described above, and then the vehicle on the pallet is transferred by the transfer device. Issued.

As described above, since the vehicles are placed on the pallet at the time of loading and unloading, the vehicles come into contact with each other and may be damaged, or the vehicles may be transferred between the transfer device and the storage shelf. Occasionally, there is no need to worry about a force being applied to the wheels of the vehicle, and it is not necessary to provide a large number of electric control parts such as various sensors on each storage shelf.
