Description

Description: TECHNICAL FIELD The present invention relates to a multi-story car park including a transporter such as a stacker crane and a shelf for storing a vehicle.

[Conventional technology]

A stacker crane type multi-level parking lot is disclosed in Japanese Patent Laid-Open No. 51-14.
As shown in Japanese Patent No. 1178, a stacker crane and a group of shelves provided with a large number of storage shelves on both sides of a traveling path of the stacker crane are provided. One end of the shelving group (a traveling path of the stacker crane) has an entrance and the other end. There is a shipping outlet at. 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. 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 expedite cargo handling. For example, JP-A-57-
There is a publication of 107303.

Further, 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 as when the store is opened (2) A pattern in which warehousing is continuous as when the store is closed (3) A pattern in which warehousing and warehousing are mixed, such as in an intermediate time zone. It is necessary to provide a large number of entrances and exits, but it becomes expensive.

In addition, although various methods of warehousing and warehousing in the case of the pattern (3) are conceivable, if the warehousing is performed, then the warehousing is performed next, and then the warehousing is performed.

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.

Therefore, in the case of the pattern (3), the stacker crane 1 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.

An object of the present invention is to make it possible to store and receive goods in a short time with an inexpensive structure.

[Means for solving problems]

The object is to arrange a plurality of storage shelves for storing a vehicle in a horizontal direction, and two shelving groups provided in parallel with each other, and a transport for transporting the vehicle by traveling between the two shelving groups. Means, the first floor on which the shelving group, the transportation means, and the traveling path of the transportation means are installed, and which stores and exits, and is installed in proximity to each other. Two loading / unloading openings installed on the second floor in the vertical direction of the floor, two elevating means connecting the respective loading / unloading openings and the respective shelving groups, and each of the two loading / unloading openings. The vehicle is connected to the approach path provided along the traveling direction of the transporting means, and is connected to each of the two storage ports, and is provided on the downstream side of the approach path in the vehicle traveling direction. Controls the exit path and the transport means and the elevating means And control means,
And the control means can be achieved by performing at least two of the following three:

(1) One of the two loading / unloading ports is used as a loading / unloading port,
The other is the exit.

(2) Both of the two entrances and exits are used as entrances.

(3) Both of the two entrances and exits are used as exits.

[Action]

The two loading / unloading ports can be switched to a combination of one loading port and the other loading port, both loading ports and both loading ports. At least two are configured to be executable. Select the usage according to the request of loading and unloading. When one is used as the entrance and the other is used as the exit, it is possible to enter and exit at the same time. When both the entrances and the exits are provided, the entry and exit can be done in a short time. Since the use of the entrance and exit is switched, it can be made cheaper than providing a large number of entrances and exits.

Each entry / exit port has an exit exit connection port downstream of the entry exit connection port. For this reason, when both of the entrances are the entrances, the distances from the entrance of the parking lot to the entrances can be substantially the same. Further, in the case where both are used as exit ports, the distance from the position for instructing the exit or the position instructing the occupant to the exit ports to the respective exit ports can be made substantially the same condition. Therefore, all users can have almost the same conditions.

Since there are two loading / unloading ports and two elevating / lowering means for the shelving groups on both sides of the traveling path of the transportation means, the transportation means, the loading / unloading port,
And the lifting means can operate independently of each other,
In particular, the transport means and the loading / unloading port can operate independently. Therefore, from this point as well, the loading / unloading time can be shortened.

If the switching is performed according to the status of the delivery request, the delivery can be prioritized and the frustration during the waiting for delivery can be prevented.

If the switching is performed depending on the number of vehicles waiting for warehousing, warehousing can be performed with priority and frustration during waiting for warehousing can be prevented.

Further, if a means for instructing the leaving by issuing a parking card and notifying the exit is provided, the exit can be easily identified and used.

The shelves with are transfer ports 11E and 11F for warehousing.

Reference numeral 21 denotes a pallet magazine having a palletizer function and a depalletizer function, which are installed on the first row of shelves in the third row of the shelf group 4 and the sixth row of the shelf group 5, respectively. As is well known, the pallet magazine 21 comprises a stacking pallet storage section 22, a supporting device 23 for supporting the stacking pallets, and a lifter 25 for moving the conveyor 24 up and down.

The essential points of the operation of the pallet magazine 21 will be briefly described for the pallet magazine 21 on the side of the shelf group 4.

A case where the empty pallets 39 are used as a palletizer for stacking will be described. When the vehicle exits from the loading / unloading port 13A, the lifter 12A is raised and the pallet on the upper surface thereof is supplied to the conveyor 24 of the pallet magazine 21 using the conveyor 10A. Next, the lifter 25 is raised to push up the pallet on the support device 23, then the support device 23 is retracted, then the lifter 25 is further raised, then the support device 23 is projected, and then the lifter 12A is raised. To lower it. By the above operation, the pallets 39 can be stacked from below.

A case where the empty pallet 39 is used as a depalletizer for picking up one by one will be described. The lifter 25 is raised to lift the stacked pallets, then the support device 23 is retracted, then the lifter 25 is lowered, and then the support device 23 is projected so that the second pallet can be supported. By lowering the lifter 25, one pallet can be taken out. This pallet is supplied to the conveyor 10A of the lifter 12A which has been lifted.

In FIG. 4, 30 is the entrance of the vehicle to the parking lot, and 31 is the exit. 32 is an exit for passengers, and 33 is an entrance.

The entrance / exit ports 13A and 13B surround the lifters 12A and 12B with fences or walls 44 and 45 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 denotes an entrance door of a vehicle to be stored, which also serves as an exit for an occupant who gets off the vehicle. 41 is an exit door of the vehicle to be unloaded,
It also serves as an entrance for passengers.

The platform 43 is on the right side because the driver's seat of the vehicle is on the right side. When a vehicle having a driver's seat on the left side is the main vehicle, 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 walls 44 of the entrance / exit openings 13A and 13B.

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

In FIG. 1, the pallet magazine 21 of the fence groups 4A and 5A arranged in parallel, the loading / unloading ports 13A and 13B, the conveyors 10A and 10B, the lifters 12A and 12B, and the conveyors 11A and 11B are the shelf groups 4 and 5, respectively. Each row is located one row younger. 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.

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

The vehicle entering from the entrance 30 temporarily stops in front of the entrance / exit entrances 13A and 13B through the approach path 35, and the passenger is alighted.

When the lifters 12A and 12B carrying the empty pallets 39 supplied from the pallet magazine 21 descend, the entrance door 4
Since 0 opens, the vehicle enters the loading / unloading ports 13A and 13B. After exiting the vehicle, the driver goes through the entrance door 40
After going out of 3A, 13B, operate the terminal device to instruct the warehousing operation. You will also receive a parking card. The driver and fellow passengers reach the exit 32 through the passage 37.

When the storage operation is commanded, the entrance door 40 is closed and the lifters 12A and 12B are raised. The on-vehicle pallets 39 of the lifters 12A and 12B are supplied to the conveyors 11A and 11B by the conveyors 10A and 10B, respectively.

The lifters 12A and 12B move down after receiving the empty pallets from the pallet magazine 21.

When the vehicle-mounted 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 groups 4 and 5. Then, the fork 2A is projected onto the conveyor 11B and the fork 2B is projected onto the conveyor 11A at the same time, and the vehicle-mounted 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 shelving groups 4 and 5.

The driver who requests the warehousing inserts a parking card into the terminal installed at the entrance 33 and commands the warehousing. Since the position (number) of the entrance / exit opening where the vehicle exits is instructed from the terminal, the vehicle goes through the passage 38 to the predetermined entrance / exit opening according to the instruction. 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 vehicle-mounted pallet from the two shelves to which the shipping instruction is issued, and stops so that the fork 2A is located on the fourth row of the shelving group 4, 5. And fork 2
A to conveyor 10A, fork 2B to conveyor 10B
To the lifter 12 which is raised at the same time and stands by.
Two vehicle-mounted pallets are simultaneously placed on the conveyors 10A and 10B on the upper surfaces of A and 12B.

Next, when the lifters 12A and 12B descend, the exit door 4
1 opens, and the driver gets in and leaves the car. Then, the passenger is stopped once, and the passengers who have passed through the passage 38 are boarded and the passage 3
Take 6 to the exit 31.

When the vehicle exits, the exit door 41 closes and the lifter 12A,
12B rises and empty pallet 35 is loaded into pallet magazine 2
Stack to 1.

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.

In a general parking lot, a vehicle waiting for entry is waiting in front of an entry / exit opening, and when a parked vehicle exits and an empty shelf appears, most of the cases immediately enter. That is, when there is a vehicle waiting for entry before the entry / exit opening 13A, 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 35 remains on the upper surface of the lifter 12A, so that a vehicle waiting for warehousing enters the warehousing ports 13A and 13B. After the driver gets off the vehicle, the entrance door 40 is closed by the storage command, the lifters 12A and 12B are raised, and the in-vehicle pallet 3 is moved.
9 is supplied to the conveyors 11A and 11B. Lifter 12
A 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. Then, if the in-vehicle pallet to be stored has been transferred to the conveyors 11A and 11B, the fork 2A is projected to the conveyor 10A and the fork 2B is projected to the conveyor 10B at the same time, and the in-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, projects them to the conveyors 11B and 11A at the same time without stopping halfway, and simultaneously takes in two vehicle-mounted pallets. Next, the stacker crane 1 stores the in-vehicle pallet in the empty shelf.

On the other hand, when the in-vehicle pallets 10A, 10B receive the pallets to be unloaded from the stacker crane 1, the lifters 12A, 1
2B descends, the exit door 41 opens, 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.

The case where the number of shelves is 1 and the number of shelves 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 by the fork 2A in response to the leaving command, and stops so that the fork 2A is located at the fourth row of the shelving group 4, 5. Next, the vehicle-mounted pallet is placed on the conveyor 10A by the fork 2A, the fork 2A is retracted, and then the fork 2A is projected onto 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 and the exit door 4
1 opens, and the driver gets in and leaves the car. Further, an empty pallet is supplied to the conveyor 10B from the pallet magazine 21 and the lifter 12B is lowered.

When the shelving command is on the fifth to eighth rows of the shelving groups 4 and 5, the stacker crane 1 takes out the on-vehicle pallet from the shelves with the forks 2B, and the fork 2B is the shelving groups 4 and 5.
Stop at the 5th line. In this case, the on-vehicle pallet is placed on the conveyor 10B by the fork 2B and then discharged. The conveyor 10A has a pallet magazine 2
Supply empty pallets from 1.

Next, the case where there are two warehousing units and one warehousing unit will be described for the shelving 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 and only in front of the entry / exit opening 13A.

Vehicles to be put in and taken out are in and out according to the procedure described above.
After entering A, the lifter 12A rises and supplies the vehicle-mounted pallet to the conveyor 11A. At the same time, the lifter 12B ascends with the empty pallet still 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 uses the forks 2A and 2B to convey the conveyor 10 respectively.
The on-vehicle pallet is placed on A and 10B. Then fork 2
B is retracted from the conveyor 10B, and then further projected to the conveyor 11A to receive the on-vehicle pallet. At this time, the fork 2A is synchronized with the fork 2B and the conveyor 10
It can be retracted from A, but it does not protrude 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 delivery 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 operation procedure.

There are other methods for entering and leaving the warehouse. For example,
In the warehousing, when a plurality of vehicles try to enter the one entrance / exit opening 13A side and there are no vehicles on the other entrance / exit opening 13B side, the stacker crane 1 operates the conveyors 11A and 10A.
The two in-vehicle pallets of A will be transported at the same time.

Further, the loading / unloading port 13A can be dedicated to loading and the loading / unloading port 13B can be dedicated to shipping. In this case, the two vehicle-mounted pallets can be simultaneously delivered to the conveyors 10B and 11B, and the two vehicle-mounted pallets can be simultaneously taken into the stacker crane 1 from the conveyors 10A and 11A. The storage port 13A located on the upstream side in the traveling direction of the vehicle is used for storage,
Since the loading / unloading port 13B on the downstream side is used for shipping, it is possible to easily drive the vehicle.

As described above, the shelving groups 4 and 5 have storage ports 13A and 1A, respectively.
3B is provided, 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, so that the time required for loading and unloading per unit can be shortened. Is. This effect can be easily understood by considering, for example, that only two vehicles are delivered or only two vehicles are received.

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

Furthermore, the pallet magazine 21 is loaded into and out of the loading / unloading ports 13A, 1A.
Since 3B is provided on the opposite side of the receiving / receiving ports 11E, 11F, the conveying 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. Further, with the above arrangement, it is possible to reduce the height of the shelf because it is not necessary to provide a transport path dedicated to the empty pallet at the bottom of the shelf. This can be understood by assuming, for example, the case where the pallet magazine 21 of the shelf group 4 is installed in the sixth row.

Also, transfer ports 10E, 10F, 1 with stacker cranes
Since 1E and 11F are installed in the center of the shelf group in the length direction, the traveling distance of the stacker crane can be minimized, and the distance from the entrance of the parking lot to the entrance / exit of the parking lot is sufficient. The vehicle can easily enter and leave the entrance and exit.

Due to the above, since a loading / unloading port, lifter, pallet magazine, and conveyor are provided for one shelf group, it is extremely efficient to store, park, and issue shelves with either a small number of shelves or a large number of shelves. Is something that can be done.

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.

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 places the in-vehicle pallets to be unloaded onto the conveyors 11B and 11A with the forks 2A and 2B, respectively, and the in-vehicle pallets to be loaded into the conveyors 10A and 10B.
Receive from.

According to this embodiment, even if the lifters 12A and 12B on which the conveyors 10A and 10B are mounted are not raised, the in-vehicle pallet to be delivered can be delivered to the transfer port.
Further, if the lifters 12A and 12B move up, the in-vehicle pallet to be stored can be received immediately, so that the waiting time of the stacker crane can be shortened.

The embodiment shown in FIG. 6 will be described. In the shelf group 4, a palletizer 41A, a storage conveyor 11A, a conveyor 10
A, a delivery conveyor 43A, and a depalletizer 42A are provided in series. In the shelf group 5, a palletizer 41B, a warehousing conveyor 11B, a conveyor 10B, a warehousing conveyor 43B, and a depalletizer 42B are provided in series. Each of the above devices in shelf group 5 is 1 to the left of each of the above devices in shelf group 4.
It is set up offset.

In such a configuration, when the warehousing and unloading are performed alternately, the stacker crane 1 simultaneously unloads to the conveyors 43A and 43B, and then the stacker crane travels for two rows to simultaneously receive the vehicle-mounted pallets from the conveyors 11A and 11B. When the vehicle-mounted pallets of the conveyors 43A and 43B are unloaded from the loading / unloading ports 13A and 13B, the loading is enabled.

Further, when the warehousing is continuously performed, the empty pallet remaining on the conveyor 10A is transferred to the palletizer 4 via the conveyor 11A.
Collect in 1A. When warehousing is continuously performed, empty pallets are supplied from the depalletizer 42A to the conveyor 10A via the unloading conveyor 43A. The same applies to the shelf group 5.

According to this embodiment, for example, when explaining the shelf group 4, the in-vehicle pallet for storage on the conveyor 10A is provided on the conveyor 11A which is the transfer port of the stacker crane 1 even when the stacker crane 1 is not in a fixed position. When the vehicle-mounted pallet is supplied, the vehicle-mounted pallet for delivery in the delivery conveyor 43A, which is the transfer port of the stacker crane 1, can be immediately conveyed to the conveyor 10A and delivered. Further, even if the conveyor 10A is not raised, the stacker crane 1 can deliver the in-vehicle pallet for delivery to the delivery conveyor 43A, and the stacker crane 1 and the lifter 12 can be delivered.
The waiting time of A can be extremely shortened. That is, even if it takes a long time for the passengers to get in and out of the loading / unloading port 13A, it can be temporarily stored in the conveyors 11A and 43A, so that the total time can be shortened.

In addition, 41A and 41B are palletizers, and 42A and 42
Although B is a depalletizer, it is a good idea to use a pallet magazine having both a palletizer function and a depalletizer function in consideration of the case where one of the rack groups fails. The palletizer and the depalletizer can have the same structure and can be used properly depending on the operation.

The embodiment shown in FIG. 7 will be described. In the shelf group 4, a pallet magazine 21, a conveyor 10A for the loading / unloading port 13A, and conveyors 45A, 46A are provided in series.
In the shelf group 5, the pallet magazine 21 and the loading / unloading port 13
The B conveyor 10B and the 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.

When the loading and unloading are performed alternately, the stacker crane 1 simultaneously exits the conveyors 45A and 46B and then simultaneously receives the on-vehicle pallets from the conveyors 46A and 46B at the same position.

In addition, the goods are simultaneously delivered to the conveyors 10A and 45B, and then
It is also possible to receive the vehicle-mounted pallets from the conveyors 45A and 46B at the same time after traveling one line.

On the contrary, the conveyors 45A and 46B are simultaneously discharged, and next,
After traveling one line, the in-vehicle pallets can be received from the conveyors 10A and 45B at the same time.

Further, the conveyors 45A, 46A (45B, 46B) or the conveyors 10A, 45A (10B, 45B) can be transferred 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 the embodiment of the system shown in FIG. 7, 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 extended to the loading / unloading port. Can be easily entered. When a plurality of sets each consisting of two shelf groups are installed side by side, between the adjacent sets, that is, the shelf group 5

Further, the loading / unloading port can be provided at the center of the shelf group.

In addition, since there are two sets of transfer systems for warehousing and two sets of transfer systems for warehousing in one set of shelves, warehousing can be performed quickly. Further, even if one of the transport systems is out of order or is in maintenance, it can be loaded and unloaded. However, in this case,
41A, 41B, 42A, 42B should be pallet magazines.

The embodiment shown in FIG. 9 is the same as the embodiment shown in FIG. 8 except for the depalletizers 42A and 42B.
B is a pallet magazine 21.

With such a configuration, since the depalletizers 42A and 42B are not provided, compared to FIG. 8, it takes a longer time to enter and leave the warehouse under specific conditions.

However, like a theater or a parking lot for picking up at a train station, incoming cars are relatively level in time and come in, but on the other hand, it is extremely effective in a parking lot that is flooded with requests for leaving. .

Also, in the embodiment of FIG. 8, the palletizers 41A, 4A
There is a configuration in which the depalletizers 42A and 42B are used as pallet magazines without providing 1B. In this case, at a hospital,
Parking cars are continuously waiting before the parking lot is opened, while the exit request is extremely effective in a parking lot that is relatively level in time.

Further, for example, in the embodiment shown in FIG.
There is a configuration in which 42A and 41B are pallet magazines except for 1A and the depalletizer 42B. This case has the features of both the above-mentioned embodiment and the above-mentioned embodiment, and is effective in a parking lot such as a department store where the entering and exiting vehicles are generally leveled in time.

〔The invention's effect〕

According to the present invention, by switching the use of the two entry / exit ports in response to the entry / exit request, a combination of the entry / exit ports, both entry / exit ports, and both exit / exit ports can be achieved, so that the configuration is inexpensive.
When there is a large demand for loading and unloading, loading and unloading can be done in a short time. Also, since each entrance / exit has an exit exit connection on the downstream side of the entry exit connection, the same conditions can be applied to the entry exit when both exits are used, and both In the case of using the exit port, the distance from the position for instructing the exit or the position instructing the occupant to the exit port is substantially the same, and all users can have substantially the same conditions. In addition, since each device can operate independently, the loading / unloading time can be shortened also from this point.
