Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a multistory parking lot.

[Conventional technology]

A stacker crane type multi-storey parking lot is disclosed in JP-A-51-141178.
As shown in Japanese Patent Publication, it consists 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. There is a shipping outlet. 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 first floor is the entrance / exit.

[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.

There are various patterns for loading and unloading. However, in a multi-storey parking lot for general use such as a store, the following three patterns are roughly divided.

(1) A pattern in which warehousing is continuous, such as when the store is opened (2) A pattern in which warehousing is continuous, such as when the store is closed (3) A pattern in which warehousing and warehousing are mixed, such as in the middle of the time There are various possible ways of entering and leaving, but once the goods have been issued, the next goods receipt is carried out, and then the goods are issued.

By the way, in the conventional stacker crane type multilevel parking lot,
An entrance is provided at one end of the traveling path of the stacker crane, and an exit is provided at the other end.

For this reason, in the case of the pattern (3), the stacker crane must make one round trip on the traveling path in order to carry out the next warehousing.

Therefore, the pattern (3) requires a great deal of time for loading and unloading.

This tendency becomes more significant as the number of parking lots increases and the length of the traveling path increases.

Further, in the conventional multi-storey parking lot, since there are an entrance and an exit, respectively, it is expensive.

Further, it is necessary to prevent contact between the vehicle and the pedestrian near the entrance / exit, but it is dangerous because the pedestrian crosses the passage of the vehicle in the related art.

An object of the present invention is to provide a safe entrance / exit port that can prevent a vehicle from crossing a pedestrian.

[Means for solving problems]

The above-mentioned purpose is to set the loading / unloading area for loading and unloading in the vertical direction (for example, below) of the storage area including the shelf group and the transport device.
It is provided in the storage area, and a loading / unloading port for both loading and unloading is provided in the loading / unloading area, and the height position of the loading / unloading port and the inside of the shelving group are connected by a lifter for transporting the vehicle. This is achieved by connecting the exit route and the approach route of the vehicle, respectively, and providing a passage for the occupant to walk above at least one of the exit route and the approach route.

[Action]

According to this, since the loading / unloading port is also used, in the pattern (3), the transport device does not necessarily make one round trip on the traveling path, and the loading / unloading time can be shortened. Further, since the loading / unloading area is provided in the vertical direction of the shelves, the loading / unloading port can be provided near the center of the traveling path of the transfer device, and the loading / unloading time can be further shortened.

In addition, the height of the storage area is different from the height of the storage area, and since the exit and entry paths can be installed in front of and behind the entrance / exit, the vehicle can enter in the forward direction and can exit in the forward direction, which makes driving the vehicle easier. And it is possible to maintain safety.

Further, since the passage for the pedestrian of the occupant is above the passage of the vehicle, it is possible to prevent the intersection of the pedestrian and the vehicle.

The storage ports 13A and 13B are surrounded by shelves or walls 44 and 45 around the lifters 12A and 12B for safety. Between the right side of the lifter and the right wall 44 in the traveling direction of the vehicle, there is a platform 43 for passengers to get on and off. Reference numeral 40 is an entrance door of a vehicle to be stored, which also serves as an exit of an occupant who gets off the vehicle. Reference numeral 41 is an exit door of the vehicle that exits the vehicle, which also serves as an entrance for passengers to board.

The platform 43 is on the right side because the driver's seat of the vehicle is on the right side. If the vehicle mainly has a driver's seat on the left side, the exit 31 side is the entrance and the entrance 30 side is the exit.

An entrance / exit for passengers may be provided on the wall 44 of the entry / exit 13A, 13B.

The platform 43 of the loading / unloading port 13A is below the traveling path 3. The platform 43 of the loading / unloading port 13B is located below the shelving group 4A arranged in parallel.

In FIG. 1, the pallet magazine 21, the loading / unloading ports 13A, 13B, the conveyors 10A, 10B, and the lifter 1 of the shelving groups 4A, 5A arranged in parallel are shown.
The 2A, 12B and the conveyors 11A, 11B are located in rows that are one row younger than the positions of the shelf groups 4 and 5, respectively. That is,
The loading / unloading port 13A of the shelf group 4A is installed at a position where at least one row of space is placed on the entrance side of the loading / unloading port 13B of the adjacent shelf group 5.

50 and 55 are passages for passengers, which are provided below the floor 9 and above the passages 35 and 36 of the vehicle. Reference numeral 50 is a passage for the occupant that has been stored, and is connected to the stairs of the exit 51. The passage 50 is below the second row. 55 is a passage for passengers wishing to leave the warehouse and is connected to the stairs at the entrance 56. The passages 50 and 55 are provided below the first and seventh rows, respectively, orthogonal to the traveling direction of the stacker crane 1 (that is, the vehicle). Normally, the vehicle can drive below 50,55. The surfaces of the loading / unloading ports 13A, 13B and the passages 50, 55 are connected at steps 53, 58. The stairs 53 and 58 are located below the traveling path 3 of the stacker crane 1. The stairs 53 and 58 are connected to the surface GL near the third and fifth rows.

In this configuration, the warehousing operation (pattern (1)) will be described for the shelving groups 4 and 5.

Vehicles entering from the entrance 30 pass through the approach path 35
Stop in front of A and 13B and get off the passenger.

When the empty pallet 39 supplied from the pallet magazine 21 is placed or the lids 12A and 12B are lowered, the entrance door 40 is opened, so that the vehicle enters the entry / exit ports 13A and 13B. After getting out of the vehicle through the entrance door 40 after exiting the vehicle, the driver operates the terminal device to instruct the warehousing operation. You will also receive a parking card. For drivers and passengers, stairs 53, aisle 5
Take exit 0 to exit 51.

When the storage operation is commanded, the entrance door 40 is closed and the lifter 12
A and 12B rise. The in-vehicle pallet 39 of the lifters 12A and 12B is
It is supplied to the conveyors 11A and 11B by the conveyors 10A and 10B, respectively.

The lifters 12A, 12B receive the empty pallets from the pallet magazine 21 and then descend.

When the in-vehicle pallets are placed on the conveyors 11A and 11B, the stacker crane 1 stops so that the forks 2A are located on the fourth row of the shelving group 4,5. And fork 2A
To the conveyor 11B and the fork 2B to the conveyor 11A at the same time, and the on-board pallet is simultaneously taken into the stacker crane 1 side. Next, the stacker crane 1 stores the in-vehicle pallet in the empty shelf.

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

Next, the delivery operation (Pattern (2)) will be described for the shelf groups 4 and 5.

The driver who requests the warehousing inserts a parking card into the terminal installed at the entrance 56 and commands the warehousing. Since the location (number) of the entrance / exit where the vehicle exits from the terminal is instructed,
Follow the instructions and go through the aisle 55, step 58 to the designated entrance / exit. The numbers of parking cards are displayed in the order of departure on the display of each entrance / exit.

The stacker crane 1 takes out the in-vehicle pallet from the two shelves for which the shipping instruction is issued, and the fork 2A is the fourth of the shelving groups 4 and 5.
Stop at the line. Then, the fork 2A is projected onto the conveyor 10A and the fork 2B is projected onto the conveyor 10B at the same time, and two vehicle-mounted pallets are simultaneously placed on the conveyors 10A and 10B on the upper surfaces of the lifters 12A and 12B which are rising and waiting.

Next, when the lifters 12A and 12B are lowered, the exit door 41 is opened, and the driver gets in and leaves the vehicle. And then stop,
The passenger who has passed through the passage 55 is boarded, and reaches the exit 31 through the passage 36.

When the vehicle exits, the exit door 41 is closed, the lifters 12A and 12B are raised, and the empty pallets 39 are stacked on the pallet magazine 21.

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, the case where the warehousing operation and the warehousing operation are alternately repeated (pattern (3)) will be described for the shelf groups 4 and 5.

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, the shelving groups 4 and 5 are provided with loading / unloading ports 13A and 13B, respectively, and one fork 2A is projected to the delivery port of one shelf group and the other fork 2B is projected to the delivery port of the other shelf group. Therefore, it is possible to shorten the time required for loading and unloading a unit. This effect can be easily understood by considering, for example, that only two vehicles are delivered or only two vehicles are received.

Further, each shelf group 4,5 is provided with two transfer ports 10E, 11E, 10F, 11F, and the positions (height, intervals) of the transfer ports are the positions of the forks 2A, 2B of the stacker crane 1 (height, It is provided according to the interval). That is, the transfer ports 10E and 11E of one shelf group and the transfer ports 11F and 10F of the other shelf group face each other with the forks 2A and 2B in between. In addition, transfer ports 10E and 10F for delivery and transfer ports 11 for storage
It faces E and 11F. Therefore, while the stacker crane is stopped, two in-vehicle pallets are simultaneously delivered to the delivery ports 10E, 10F for delivery, and at the same stop position, the two delivery ports 11F, 11E for delivery on the opposite side The on-board pallet can be received at the same time, and the warehousing and unloading can be performed in an extremely short time.

Furthermore, the pallet magazine 21 is provided on the opposite side of the receiving / receiving ports 11E, 11F across the loading / unloading ports 13A, 13B, whereby the transport distance of empty pallets can be minimized. In particular, when warehousing and warehousing are alternately repeated, empty pallets need not be transported at all, and warehousing and warehousing can be performed more efficiently and in a short time. Also, with the above arrangement, it is not necessary to provide a transport path for empty pallets at the bottom of the shelf,
The height of the shelf can be reduced. This can be understood by assuming, for example, the case where the pallet magazine 21 of the shelving group 4 is installed in the sixth row.

In addition, the stacker crane transfer ports 10E, 10F, 11E, 11F
Since it is installed in the center of the shelf group in the longitudinal direction, it is possible to minimize the distance traveled by the stacker crane, and also to ensure a sufficient distance from the entrance of the parking lot to the entrance and exit of the parking lot. The vehicle can easily enter and leave the entrance and exit.

From the above, by providing a set of loading / unloading port, lifter, pallet magazine, and conveyor for one shelf group,
Regardless of whether the shelves have a small number of rows or a large number of shelves, it is possible to store, park, and leave the warehouse extremely efficiently.

Furthermore, when arranging shelves in parallel, the loading / unloading port, lifter, etc. are installed with at least one row offset, so the space for the platform for passengers to get on and off should be located below the other shelves. The effect is that no special space is required between the opposite shelves.

Further, since the occupants' passages 50, 55 are provided above the vehicle's passages 35, 36, the occupants do not cross the vehicle's passages 35, 36, which is a safety feature. In particular, it is effective in a large parking lot where a large number of entrances and exits are arranged in parallel. In addition, since the step of connecting the entrance / exit surface and the passages 50, 55 is provided below the traveling path 3 of the stacker crane 1, the space can be effectively used, and the axial size of the multi-storey parking lot can be increased. It can be prevented.

In the embodiment shown in FIG. 5, in the shelving groups 4 and 5, the receiving and delivering ports are exchanged with each other. The stacker crane 1 forks an on-board pallet to be delivered
2A, 2B are placed on the conveyors 11B, 11A, respectively, and the in-vehicle pallets to be stored are received from the conveyors 10A, 10B.

According to this embodiment, even if the lifters 12A and 12B on which the conveyors 10A and 10B are placed are not lifted, the in-vehicle pallet to be delivered can be delivered to the transfer port.
As soon as A and 12B are raised, the on-board pallet to be loaded can be immediately received, so that the waiting time of the stacker crane 1 can be shortened.

The embodiment shown in FIGS. 6 and 7 will be described. Shelf group 4
At the conveyor of pallet magazine 21 and loading / unloading port 13A
10A and conveyors 45A and 46A are provided in series. In shelf group 5, pallet magazine 21, conveyor 10B for loading / unloading port 13B,
Conveyors 45B and 46B are provided in series. Each of these devices is installed in the same row in the shelf group 4 and the shelf group 5.

Stacker Crane 1 for loading and unloading alternately
Simultaneously exits the conveyors 45A and 46B, and then simultaneously receives the in-vehicle pallets from the conveyors 46A and 46B at the same position.

It is also possible that the conveyors 10A and 45B are simultaneously unloaded, and after traveling for one line, the in-vehicle pallets are simultaneously received from the conveyors 45A and 46B.

On the contrary, it is possible to receive the vehicle-mounted pallets from the conveyors 10A and 45B at the same time after leaving the conveyors 45A and 46B at the same time and traveling for one line.

In addition, the conveyor 45A, 46A (45B, 46B), or the conveyor 10A,
45A (10B, 45B) can be given and received as a set. The conveyors 46A and 46B are buffers.

The efficiency can be improved by appropriately switching and using them according to the situation.

In this embodiment, since the loading / unloading port 13A and the loading / unloading port 13B can be installed in the same row, for example, the straight line portion of the approach path 35 in front of the loading / unloading port can be lengthened to facilitate entry into the loading / unloading port. .

In addition, since the loading / unloading port 13B of the shelf group 5 and the loading / unloading port 13A of the adjacent shelf group 4A are installed in the same row, between the adjacent groups, that is, the shelf group 5 and the shelf group 4 A space for the platform 43 is provided between the and.

In FIG. 7, the passage 50 is used for both getting on and off. Reference numeral 60 is a passage for exit.

Further, it is possible to add a step to the gap S.

In each of the above embodiments, the stacker crane 1 has two forks, but the stacker crane 1 also has one fork.

In each of the above-described embodiments, the storage area of the shelf is provided above the storage / reception area, but it can be provided below. FIG. 8 shows an example thereof. The lifters 12A and the like are designated by the shelf group 4. 49 is the floor for approach road 35 etc.
