Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-storey parking lot including a transporter such as a stacker crane and a shelf for storing a vehicle.

In the present invention, the "incoming and outgoing" means at least one of "incoming" and "outgoing". The same applies to the "in / out gate".

[Background of the Invention]

A stacker crane type multi-storey parking lot is disclosed in JP-A-51-76.
No. 76 and Japanese Patent Laid-Open No. 51-141178, a stacker crane and a group of shelves provided with a large number of storage shelves on both sides of a traveling path are provided. The entrance and exit are provided at the end of. The stacker crane includes a traveling body, an elevating body that elevates and lowers the traveling body, and a fork that advances and retracts from the elevating body to the storage shelf side.
Since the fork is a set, loading and unloading are performed on a vehicle-by-vehicle basis.

It is known that, in a general three-dimensional warehouse, two sets of forks are provided in a stacker crane so that two units can be loaded and unloaded to facilitate cargo handling.

For example, JP-A-57-107303 and JP-A-5757
-107304 and JP-A-57-199704.

In addition, what is disclosed in Japanese Utility Model Laid-Open No. 56-154903 is a warehouse, where shelves and stacker cranes are installed on the second floor and above of the building, and a cargo handling area is provided at the bottom of the shelves. And are connected to each other by a load lifting / lowering conveyance means. The means for lifting and lowering loads is below the shelf. The first floor is the entrance / exit.

In order to reduce the time required for loading and unloading, it is conceivable to provide the transfer means with two sets of transfer devices. According to this
Two vehicles can be simultaneously conveyed between the entrance and the shelving group, and between the group shelves and the exit, so that the loading time per vehicle can be reduced to half.

For example, in the exit port, two exit ports are provided only on one of the shelves on both sides, and two vehicles can be arranged in series to exit. In this case, since the driver can get on each vehicle, the boarding time can be halved.

However, in the exit port configured so that two vehicles are placed in series, the vehicle behind the exit port can only exit after the vehicle in front exits from the exit port. For this reason, the front vehicle is delayed in exiting due to, for example, loading baggage, but the rear vehicle cannot travel during that time.
In the worst case, the driver of the vehicle in front cannot drive because of absence.

Similarly, when two storage openings are arranged in series in the front and rear, it is necessary to elevate a mirror or the like for the vehicle behind between the front and rear storage openings, but this configuration is complicated. It is possible that

In addition, at the exit, since there is a car stop protruding upward on the road surface or on the pallet, the vehicle behind must get over the car stop at its own exit and the car stop at the front exit, which makes the ride uncomfortable. It's hard to drive. This also applies to the entrance. That is, it is necessary for a vehicle entering the storage entrance on the far side to get over the car stop at the front storage entrance.

As described above, only by providing two sets of transfer devices in the transport means, the loading / unloading time is not shortened, and it is difficult for the driving vehicle to use.

[Object of the Invention]

It is an object of the present invention to enable quick and easy loading / unloading at a loading / unloading port in a case of using a conveying means having two sets of transfer devices such as forks.

[Outline of Invention]

According to the present invention, each of the shelving groups on both sides is provided with a loading / unloading port and a transfer port for transferring means, and when one of the transfer devices can transfer a vehicle to or from one of the transfer ports, the other transfer device is It is characterized in that the vehicle is provided so as to be able to transfer to and from the other transfer port.

According to this, at the entrance / exit, the two vehicles can enter and exit independently.

There is a storage entrance 10A, 10B at one end of the shelf group 5, 6.
There are exit ports 20A and 20B at the other end. This entrance 10
A, 10B and outlets 20A, 20B are equipped with conveyors 11A, 11B, 21A, 21B for carrying on-vehicle pallets. Also,
For safety, the area is surrounded by fences to form a storage room and a storage room, and a gate is provided at the passage for people and cars. A mirror 12 is arranged between the shelving groups 5 and 6 at the storage entrances 10A and 10B, and is raised when passing through an on-vehicle pallet.

The entrance 10A and the exit 20A are provided outside the end of the shelf group 5. The entrance 10B and the exit 20B are provided in the first row of storage shelves at the end of the shelf group 6. The ceilings of the entrance 10B and the exit 20B are provided at a required height so that people can enter. Further, a wall for safety is provided on the ceiling and the side of the traveling path 4.

15A and 15B are transfer ports between the storage ports 10A and 10B and the stacker crane 1, and conveyors 16A and 16B connected to the conveyors 11A and 11B of the storage ports 10A and 10B are provided below the transfer ports. 17A and 17B are outlets and outlets between the outlets 20A and 20B and the stacker crane 1, and below the outlets 20A and 20B.
Conveyors 18A and 18B connected to the conveyors 21A and 21B. The conveyors 16A, 16B, 18A, 18B are configured to transfer pallets to and from the forks 2A, 2B of the stacker crane 1. Transfer port 15A, 17A
Is in the storage shelf on the first row from the end of the shelf group 5.

When the fork 2A is interacting with the transfer port 15A, the fork 2B can interact with the transfer port 15B. Fork 2B
When the fork 2A is communicating with the transfer port 17A, the fork 2A can communicate with the transfer port 17B.

A conveyor line 25 is provided below the first-stage storage shelves of the shelving groups 5 and 6. This conveyor line 25 is the exit
It is for supplying empty pallets 40 of 20A, 20B to the receiving ports 10A, 10B. Conveyor 11A at the entrance and exit
11B, 21A and 21B are lifters 27A, 27B and 28A, respectively.
28B, and moves up and down between the conveyors 16A, 16B, 18A, 18B and the conveyor line 25. The approach path 27 and the exit path 28 are substantially at the same height as the conveyor line 25.

Reference numeral 35 is a known pallet magazine, which is provided under each of the shelves 5 and 6. The pallet magazine 35 comprises a stacking pallet storage section 36 provided on the first storage rack, a support device 37 for supporting the stacking pallets, and a lifter 38 for moving up and down one conveyor 25e in the conveyor line 25. .

The pallet magazine 35 is for cutting out and feeding the stacked pallets one by one, and for stacking the empty pallets fed one by one from the conveyor line 25. Since such a pallet magazine itself is known, the essential points of its operation will be described.

When stacking pallets, the pallet 40 conveyed from the delivery port 20 by the conveyor line 25 is pushed up to the storage unit 36 by the conveyor 25e using the lifter 38, the support device 37 is retracted, and one pallet is further stacked. Lifting the lifter 38 and supporting device
37 is projected to support stacked pallets.

To remove the pallet, the conveyor 25e is raised to push up the stacked pallets, the supporting device 37 is retracted, then the conveyor 25e is lowered by one pallet, the supporting device 37 is projected, and the conveyor 25e is lowered. Then, one pallet is taken out. This pallet is a conveyor line 25
It is sent to the storage entrance 10.

A plurality of pallets are placed on the conveyor line 25. However, the conveyors 25f, 25 near the exit ports 20A, 20B
Normally, there is no pallet on g, and the exit ports 20A, 20
The empty pallet of B can be collected immediately.

The side of the storage unit 36 on the side of the stacker crane 1 is provided with an opening for transferring stacked pallets.

Both ends of the traveling path 4 of the stacker crane 1 are surrounded by fences 41.

The operation of this configuration will be described. Stacker crane 1 is 2
Since it can be transported in units of units, this case will be mainly described.

First, the case of warehousing will be described.

The vehicle entering the site of the multi-storey parking lot from each approach road 27 stops immediately before each entrance 10A, 10B to let the passenger get off. This is because the left door of the vehicle cannot be opened especially at the entrance 10B. In this embodiment, a right-hand drive vehicle is mainly used. If the left-hand drive vehicle is the main vehicle, the positions of the entrance and exit are reversed.

Conveyor 11 from the conveyor line 25 to the entrance 10A, 10B
When pallets are supplied to A and 11B, storage entrances 10A and 10B
Opens the gate. When the passenger exits the vehicle at the entrances 10A and 10B and issues an instruction to enter the goods outside the entrances, the lifter 27
A, 27B and the mirror 12 are raised, the conveyors 11A, 11B,
Operate 16A and 16B and carry them into the transfer ports 15A and 15B. The stacker crane 1 projects the fork 2A toward the transfer port 15A side and the fork 2B toward the transfer port 15B side to receive two vehicle-mounted pallets. Then, the stacker crane 1 conveys it to a predetermined storage rack.

Next, the case of warehousing will be described.

When the stacker crane 1 on which two vehicle-mounted pallets for which a shipping instruction has been issued is stopped at a predetermined position of the transfer port, the fork 2B is projected toward the transfer port 17A, and the fork 2A is projected toward the transfer port 17B. Transfer to conveyors 18A and 18B. Then, it is conveyed to the raised conveyors 21A and 21B and lifter 28
Lower A and 28B. Next, open the doors of the exit ports 20A and 20B, get on, and move forward. Then, the vehicle is stopped and the passenger is boarded.

The empty pallets at the exit are collected on conveyors 25f and 25g. At this time, if there is a request for empty pallets from the entrance,
Each empty pallet is conveyed to the entrance side by one pallet. If not requested, the pallets on the conveyor 25e are stacked in the storage unit 36, and then the pallets of the conveyors 25f and 25g are conveyed toward the conveyor 25e by one pallet.

When a predetermined number of pallets are stacked in the storage unit 36 due to continuous unloading, the stacker crane 1 conveys the pallets to an empty rack. When the pallets are exhausted from the storage unit 36 due to the continuous storage, the stacker crane 1 carries the stacked pallets from the storage shelves.

When the stacker crane 1 handles two vehicle-mounted pallets, the two sets of forks 2A and 2B can be operated simultaneously.

When the warehousing and warehousing are not continuous, the stacker crane 1 conveys one by one.

As described above, since the entrances 10A and 10B and the exits 20A and 20B are provided in parallel with each other, compared to the case where two entrances are provided in series or two exits are provided in series, It has the following effects.

Explaining the case of the exit port, in the case where the vehicles are installed in series, if the front vehicle is delayed in exiting, the rear vehicle is delayed in exiting. In particular, it becomes a serious problem when the driver of the vehicle ahead cannot leave because of absence. In the present embodiment, since two delivery ports are provided in parallel, there is no such problem.

Further, the pallet generally has car stopper stoppers protruding so as to sandwich the front and rear of the wheels of the mounted vehicle. When you leave the warehouse, you have to get over this protruding stopper. When the two exits are provided in series, the vehicle on the back side must pass through the pallet in the front, which makes the riding comfort extremely bad. The present invention does not have such a problem.

Explaining the case where two storage openings are provided in series,
The problem of riding comfort can be solved.

Further, when the two entrances are provided in series, it becomes extremely difficult to lower the mirror or the like that displays the stop position of the vehicle behind. Since the two vehicles must enter at a certain distance, the time required for warehousing will be long as a result. In the present invention, since two storage openings are provided in parallel,
There is no such problem.

Furthermore, the two transfer ports 15A, 15B, 17A, and 17B connected to these two input / output ports are the stacker crane 1
Since the forks 2A and 2B are provided at positions corresponding to the forks 2A and 2B, it is not necessary to move the stacker crane 1 when transferring and receiving the two vehicle-mounted pallets, and the transfer can be performed at one stop point. Therefore, the time can be shortened.

In the above embodiment, the entrance or exit and the transfer entrance are separate, but they can be the same.

Although the forks 2A and 2B are used as the transfer device, other means can be used. Between the entrances 10A and 10B and the exits 20A and 20B, a passage is provided underground in a direction orthogonal to the traveling direction of the stacker crane 1, and the passage and the space 8
If you connect with the stairs, you can construct a passage (sidewalk) that connects the entrance and exit to the outside of the parking lot. According to this, it is possible to prevent the occupant and the vehicle from crossing and to ensure safety.

The present invention can also be applied to a system in which a loading / unloading port is provided on the first floor and a stacker crane and a shelf are provided on the second floor and above, as in Japanese Utility Model Laid-Open No. 56-154903.

〔The invention's effect〕

According to the present invention, two vehicles can be easily loaded and unloaded in a short time during loading and unloading.
