DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
As shown in Japanese Patent No. 7303, if two sets of transfer devices are provided in the transfer means, two vehicles can be transferred between the storage entrance and the storage shelf, and between the storage shelf and the exit, respectively. The loading time can be shortened.

For example, at the exit port, only one of the shelving groups on both sides is provided with the exit port, and two vehicles are connected in series to the exit port for exiting. in this case,
Since the driver can get on each vehicle, the boarding time can be halved. However, the vehicle behind the exit can only exit after the vehicle in front exits the exit. For this reason, if the front vehicle is delayed in exiting due to, for example, loading baggage, the rear vehicle cannot travel during that time. In the worst case, the driver of the vehicle in front cannot drive because of absence.

The present invention is to make it possible to store and receive goods in a short time.

[0009]

The present invention comprises a group of shelves in which a plurality of storage shelves for storing a vehicle are arranged in a horizontal direction, and a conveying means for traveling along the group of shelves to convey the vehicle.

Reference numeral 2 is a driver door, and 53 is a vehicle gate.

The platforms 46 and 51 of the entrance 20A and the exit 25A are located below the traveling path 4. Platforms 46 and 5 of the entrance 20B and the exit 25B
1 is located below the space 8.

The storage operation in this configuration will be described.

The vehicle entering through the entrance 40 temporarily stops in front of the entrances 20A and 20B through the approach path 15 and dismounts the passenger. The passenger reaches the passage 17 through the passage 60. When the lifters 21A and 21B on which the pallet is placed descends, the gate 48 opens, so that the vehicle is loaded into the storage openings 20A and 20B.
Enter B. When entering the vehicle, the gate 48 is closed. After exiting through the door 47, the driver operates the terminal device to instruct the warehousing operation. You will also receive a parking card.

When the warehousing operation is instructed, the lifter 21A,
21B rises. The on-vehicle pallet of the lifter 21A is conveyed to the conveyor 27 via the conveyor 26. The on-vehicle pallet of the lifter 21B is supplied to the conveyor 28.

The lifters 21A and 21B receive the pallets from the pallet magazine 33 and then descend.

When the vehicle-mounted pallets are placed on the conveyors 27 and 28, the stacker crane 1 stops so that the fork 2A is located at the second line. Then, the fork 2A is moved to the conveyor 27 and the fork 2B is moved to the conveyor 2
Simultaneously project to 8 and take in at the same time. After that, the stacker crane 1 stores the in-vehicle pallet in the blank.

As described above, the stacker crane 1 simultaneously conveys two vehicle-mounted pallets when the warehousing is continuous. In other cases, the stacker cranes 1 convey the vehicle-mounted pallets one by one.

Next, the delivery operation will be described.

A person who requests the warehousing inserts a parking card into a terminal installed at the doorway 42 and instructs the warehousing. Since the position (number) of the exit port for exiting the product is instructed from the terminal device, the user goes to the predetermined exit port in accordance with the instruction. The number of the parking card is displayed in the shipping order on the display of each shipping exit.

The on-vehicle pallets conveyed to the conveyors 30 and 31 are conveyed to the raised conveyors 24A and 24B.
When the conveyors 24A and 24B descend, the door 52 and the gate 53 open. The driver gets in and leaves the car. And
The passenger is stopped once and the passengers who have passed through the passage 62 are boarded.

When the delivery requests are continuous, the stacker crane 1 takes out the two on-vehicle pallets and stops so that the fork 2A is located on the sixth line. Then, the fork 2A is moved to the conveyor 30, and the fork 2B is moved to the conveyor 3.
1 is projected at the same time, and two vehicle-mounted pallets are placed on the conveyors 30 and 31 at the same time.

As described above, the storage ports are provided in the rack groups 5 and 6, respectively, and the transfer port of one shelf group corresponds to the transfer port of the other shelf group so that the transfer port of the other shelf group corresponds to the other fork. It is provided to correspond. Therefore, two vehicle-mounted pallets can be transferred at the same time, and the warehousing can be performed in a short time.

On the other hand, since the delivery port side is also similarly configured, the delivery can be performed in a short time.

Generally, it is required that a large number of vehicles be loaded and unloaded in a short time, but it is desirable to give priority to unloading rather than warehousing. For this reason, it is desirable that the conveyors 30 and 32, which are delivery ports for delivery, be provided at the center of the shelf group in the length direction.

On the other hand, from the entrance 40 to the entrance 20A, 20B
It is desirable that the straight line distance L ₁ to the vehicle be as large as possible in order to make it easy for the vehicle to enter the center of the storage entrance (which means the center in the vehicle width direction).

Therefore, as shown in the drawing, the positions of the conveyors 30 and 31 tend to be closer to the end side than the longitudinal center of the shelf group.

In this case, the vehicle exit 2 of the conveyor 31
Since 5B is provided on the entrance side and is provided on the exit 25 of the vehicle of the conveyor 30, the distance L ₂ from the entrance to the exit can be reduced, and the distance L ₃ for the area of the exit route 16 can be reduced.
Can also get enough. As described above, the two entrances 20A, 20B are provided in the same row, and the two exits 25A,
Since 25B is provided in a different row, the distance from the entrance to the exit can be reduced, and the distance L _{1 for} the approach path 15 and the distance L ₃ for the exit path 16 can be sufficiently obtained. Therefore, it can be applied to a small number of lines.

Pallet magazine 3 between the entrance and exit
Since 3 is provided, the number of pallet magazines can be reduced. Further, since the passage 17 is provided below the pallet magazine 33, the distance L ₂ can be further reduced.

Except for the outlet 24A, since there are conveyors 26, 27, 28, 31 as transfer ports and a pallet magazine 33 centering on the lifters 21A, 21B, 23B in the rack group, the transfer of empty pallets and vehicle-mounted pallets is carried out. The distance can be shortened and the time required for loading and unloading can be shortened.

If, for example, the conveyor of each lifter is configured to be able to send and receive an on-vehicle pallet to and from the fork of the stacker crane, the upper and lower shelves of the lifter also serve as a transfer port. Therefore, for example, there is a combination of the conveyor 22A and the conveyor 28.

In the embodiment shown in FIG. 5, the exit 25 of the shelf group 5 is used.
The positions of A (conveyor 24A) and conveyor 30 are exchanged. The stacker crane 1 leaves the conveyor 30 with the fork 2A and the conveyor 68 with the fork 2B on the eighth row of the shelf group 6. The on-vehicle pallet of the conveyor 68 can be conveyed to the conveyor 31. No conveyor is required below the conveyor 30 of the shelf group 5. According to this embodiment, the distance from the entrance to the exit can be reduced, so that the first floor of the ninth row can be used as a machine room or the like.

[0052]

According to the present invention, since the transfer port and the pallet magazine are provided centering on the lifter, the transport distance of empty pallets and vehicle-mounted pallets is shortened, and the loading / unloading time can be shortened.
