Description

TECHNICAL FIELD The present invention relates to a multistory parking lot, and more particularly to a stacker crane type multistory parking lot.

[Conventional technology]

The stacker-clay type multi-storey parking lot is composed of a stacker crane and a group of shelves provided with a large number of storage shelves on both sides of the traveling path of the stacker crane, as disclosed in Japanese Patent Laid-Open No. 51-141178. An entrance is provided at one end and a exit is provided at the other end. Stacker crane
It comprises a traveling body, an elevating body that elevates and lowers the traveling body, and a fork that advances and retreats from the elevating body toward the storage shelf. There is one set of forks, and the loading and unloading is performed for each vehicle.

Further, the vehicle is mounted on a pallet for storage. For this reason, a depalletizer is installed near the entrance.
The stacked pallets are divided and supplied to the storage entrance one by one. In addition, a palletizer is installed near the exit,
We collect and stack pallets that are no longer needed when a vehicle is unloaded.

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 speed up cargo handling. For example, JP-A-57-10
There is a 7303 publication.

In addition, what is disclosed in Japanese Utility Model Laid-Open No. 56-154903 is a warehouse, in which a group of shelves and a stacker crane are installed on the second floor and above of the building, and a cargo handling area is provided at the bottom of the shelf. The floors are connected by means of lifting and lowering transportation means. The means for lifting and lowering loads is below the shelf. The entrance is on the 1st floor.

[Problems to be solved by the invention]

In a multi-storey car park, it is desirable that the time from the desire to enter the warehouse to the actual parking and the time from the desire to leave the warehouse to the actual parking can be as short as possible.

Therefore, it is conceivable to provide a loading / unloading port on each of the shelving groups on both sides of the stacker crane to shorten the time required for loading / unloading per unit.

In a large multi-storey car park, a stacker crane and a group of shelves on both sides of the stacker crane will be installed in parallel as a set. In this case, at the entrance / exit, at least the driver's seat side (for example, the right side) needs to have a platform for opening and closing the vehicle door to allow the driver to get on and off. Therefore, when the groups are arranged side by side, a gap for the platform is required between the groups. This gap requires about 1 m, for example. Therefore, a plurality of sets cannot be installed side by side on a small site, which reduces the number of parking lots.

The present invention is to reduce the required size in the width direction of a multi-storey car park.

[Means for solving problems]

The above object is to provide a shelf group including a plurality of shelves, a transport device that travels along the shelf group to transport a vehicle, a vehicle for traveling and walking of an occupant. A loading / unloading area provided in a vertical direction of a storage area including a transporting device, and an entry / exit area installed in the loading / unloading area for loading and unloading a vehicle and having a platform for getting on and off. An exit port, a travel path for entry or exit of a vehicle connected to the entry port along the traveling direction of the transport device, and a vehicle between a height position of the entry port and the shelf group. And a lifter that moves up and down, and the rack group, the transport device, the loading / unloading port, and the lifter are set as one set, and at least two sets are arranged in parallel. The first set of the rack group To the second group of shelves adjacent to Has a shelf length of at least one minute line in the traveling direction of the transport device between the first and second loading / unloading ports, and the loading / unloading port having the length of the one row shelf. This can be achieved by setting the route as a vehicle path.

[Work]

For warehousing, when an occupant gets off at the warehousing entrance / exit, the vehicle is transported by the lifter to a group of shelves in a storage area in the vertical direction of the warehousing / unloading area. Next, it is transported by the transport device and stored in the shelf group.

The warehousing is taken out from the shelves by the carrying device according to the command, carried to the lifter, and carried to the warehousing port by the lifter.

In the loading / unloading area, a length of a shelf for one line is provided between the loading / unloading ports of two adjacent groups in the traveling direction of the transport device, and the loading / unloading of the length of the rack for one line is performed. Since the space between the mouths is the traveling path of the vehicle, for example, the vehicle can be driven so as not to come into contact with the platform of the second set of loading / unloading ports adjacent to the front of the loading / unloading port of the first set. . Therefore, the gap between the first group and the second group can be set small, and the required size in the width direction of the multi-storey parking lot can be reduced.

In the invention of the present application, the entry / exit port refers to either the entry port, the exit port, or the dual port of the both.

As described above, the stacker crane 1 simultaneously conveys two vehicle-mounted pallets when the unloading is continuous, and in other cases, the pallets are conveyed one by one.

Next, a case will be described with respect to the shelving groups 4 and 5 in which the warehousing operation and the warehousing operation are alternately repeated.

Generally, in a parking lot, a vehicle waiting to enter is waiting in front of an entrance / exit, and when a parked vehicle exits and an empty shelf comes out, most of the cases immediately enter. That is, when there is a waiting vehicle in front of the entry / exit openings 13A and 13B, the exit door 41 is opened and the vehicle exits, and then the exit door 41 is closed and the entrance door 40 is opened at the same time. An empty pallet 39 is left on the upper surfaces of the lifters 12A and 12B, and a vehicle waiting to enter the vehicle enters the entry / exit ports 13A and 13B. After the driver gets off the vehicle, the entrance door 40 is closed by a storage command, and the lifter 12
A and 12B rise, and the on-vehicle pallet 39 is supplied to the conveyors 11A and 11B. The lifters 12A and 12B stand by in a raised state.

While carrying out the above warehousing work, stacker crane 1
Took out the two in-vehicle pallets for which the dispatch command was issued,
The fork 2A is stopped so as to be located on the fourth row of the shelving group 4,5. And the in-vehicle pallet to be stored is the conveyor 11A,
If it has been moved to 11B, the fork 2A is projected onto the conveyor 10A and the fork 2B is projected onto the conveyor 10B at the same time, and the on-vehicle pallet is placed on the conveyors 10A and 10B at the same time.

Next, the stacker crane 1 retracts the forks 2A and 2B from the conveyors 10A and 10B at the same time, without stopping midway,
Further, the conveyors 11B and 11A are simultaneously projected, and two on-board pallets are simultaneously taken in. Next, the stacker crane 1 stores the in-vehicle pallet in the empty shelf.

On the other hand, when the conveyors 10A, 10B receive an on-vehicle pallet to be unloaded from the stacker crane 1, the lifters 12A, 12B are lowered, the exit door 41 is opened, and the driver gets in and exits.

After that, this is repeated.

In this way, the stacker crane 1 simultaneously conveys two vehicle-mounted pallets when the warehousing and warehousing are continuous.

A case where either one of the delivery and the receipt is one will be described.

A case where the number of shelves is 1 and the number of receipts is 2 will be described for the shelving groups 4 and 5.

The two vehicles to be stored are simultaneously supplied to the conveyors 11A and 11B by the procedure described above. The stacker crane 1 takes out the on-vehicle pallet from the shelf with the fork 2A in response to the delivery command, and stops so that the fork 2A is located at the fourth row of the shelving group 4,5. Next, the on-vehicle pallet is placed on the conveyor 10A by the fork 2A, the fork 2A is retracted, and then the fork 2A is projected to the conveyor 11B. At this time, the fork 2B is projected onto the conveyor 11A in synchronization with the fork 2A, and two vehicle-mounted pallets are simultaneously taken in. After that, the stacker crane 1 stores two vehicle-mounted pallets in the empty shelf.

On the other hand, when the conveyor 10A receives the vehicle-mounted pallet from the stacker crane 1, the lifter 12A descends, the exit door 41 opens, and the driver gets in and exits. Further, an empty pallet is supplied to the conveyor 10B from the pallet magazine 21 and the lifter 12B is lowered.

The stacker crane 1 forks the on-vehicle pallet when the shelves instructed to exit are on the 5th to 8th rows of the shelving groups 4 and 5.
Take out from the shelf by 2B, and stop so that the fork 2B is located on the fifth row of the shelving group 4,5. In this case, the on-vehicle pallet is placed on the conveyor 10B by the fork 2B and then delivered. Further, empty pallets are supplied from the pallet magazine 21 to the conveyor 10A.

Next, the case where there are two warehousing units and one warehousing unit will be described for the shelf groups 4 and 5. For example, a case will be described in which there are two delivery commands, but there is no vehicle waiting for entry at the entry / exit opening 13B but only in front of the entry / exit opening 13A.

Vehicles entering and exiting should follow the steps described above to enter / exit the entrance / exit 13A.
Enters, the lifter 12A rises, and the in-vehicle pallet is conveyed to the conveyor 1
Supply to 1A. At the same time, the lifter 12B ascends while the empty pallet remains loaded, and the empty pallet is stacked on the pallet magazine 21 by the conveyor 10B. The stacker crane 1 receives two vehicle-mounted pallets from the shelves and puts the vehicle-mounted pallets on the conveyors 10A and 10B with the forks 2A and 2B, respectively. Next, the fork 2B is retracted from the conveyor 10B, and then is further projected to the conveyor 11A to receive the on-vehicle pallet. At this time, the fork 2A can be retracted from the conveyor 10A in synchronization with the fork 2B, but does not project to the conveyor 11B. The stacker crane stores one vehicle-mounted pallet in an empty shelf.

The above operation is performed by a computer. The computer detects the status of the shipping request, the presence / absence of pallets at the loading / unloading ports 13A and 13B and the transfer ports, the number of vehicles waiting to be loaded, and the like to determine the operating procedure.

There are other methods for entering and leaving the warehouse. For example,
When a plurality of vehicles try to enter one of the entrance / exit ports 13A and there are no vehicles on the other entrance / exit port 13B, the stacker crane 1 conveys two vehicle-mounted pallets of conveyors 11A and 10A at the same time. Will be done.

Further, the entry / exit port 13A can be dedicated to entry and the entry / exit port 13B can be dedicated to exit. In this case, two on-board pallets are simultaneously delivered to the conveyors 10B and 11B, and the two conveyors 10A and 11A
One vehicle-mounted pallet can be taken into the stacker crane 1 at the same time. Since the loading / unloading port 13A located on the upstream side in the traveling direction of the vehicle is for loading and the loading / unloading port 13B on the downstream side is for loading, it is possible to easily drive the vehicle.

As described above, since the loading / unloading port, the lifter, and the like are installed at least one line apart, the space for the platform for passengers to get on and off can be located below the other shelves, and the shelves facing each other The effect is that no special space is required between them.

In the above embodiment, the conveyors 11A and 11B may be used for warehousing and the conveyors 10A and 10B may be used for warehousing.

Further, the loading / unloading ports 13A and 13B can be installed in the same row.
