Description

The present invention relates to a multi-story parking lot in which a large number of storage shelves are arranged along the horizontal and vertical directions, and in particular, a multi-story parking lot equipped with a stacker crane as a transportation means. The present invention relates to a method and apparatus for storing a vehicle.

[Conventional technology]

Japanese Laid-Open Patent Publication No. 62-
As disclosed in Japanese Patent No. 174462, a stacker crane for three-dimensionally transporting a vehicle, a group of shelves provided with a large number of storage shelves along both sides of a traveling path of the stacker crane, and a stacker provided below the shelving group. It comprises a shipping port and a loading / unloading lifter that connects the shipping port with the inside of the shelving group.

The stacker crane is a traveling body that travels along the shelves,
It is composed of an elevating body that elevates and lowers the traveling body, and a fork that advances and retreats from the elevating body with respect to the storage rack. A pallet with the vehicle is placed on the fork.

In addition, a pallet magazine is installed in the shelving group near the loading / unloading port. The pallet magazine supplies pallets to the loading and unloading lifters and collects pallets that are no longer needed when the vehicle is unloaded.

The entrance / exit entrance and the vehicle passage for entrance / exit are below the shelving group and the traveling path of the stacker crane. The entrance / exit is below the shelves. The vehicle that has entered the loading / unloading port is carried into the rack group by the lifter and placed on the conveyor in the rack group. The stacker crane transfers the on-vehicle pallets on this conveyor to the storage shelves. Delivery is performed in the reverse order of the above. One end side of the loading / unloading port is connected to the approach path of the vehicle, and the other end side is connected to the exit path of the vehicle.

In the multi-level parking lot disclosed in JP-A-61-75173, an entrance is provided at one end in the longitudinal direction of the shelving group and an exit is provided at the other end.

[Problems to be solved by the invention]

This kind of multi-storey car park is generally installed in the city and used for parking an unspecified number of people (vehicles). Therefore, there are various types of parked vehicles, from light vehicles to heavy vehicles.

However, conventionally, for light-weight vehicles and heavy-duty vehicles, storage shelves to be parked are similarly determined and transported by a stacker crane.

The power consumption of the stacker crane is largely related to the weight of the vehicle to be transported and the transportation distance.

However, since the conventional transfer method is as described above, there is a problem in that the power consumption is large because the power consumption is not arranged.

It is an object of the present invention to reduce the power consumption of a carrier that carries a vehicle, travels and ascends and descends, and carries a vehicle from an entrance to an exit via a desired storage shelf.

A second object of the present invention is to be able to store a predetermined number of heavy vehicles.

A third object of the present invention is to reduce power consumption for transporting a lightweight vehicle.

[Means for solving problems]

According to the present invention, a heavy vehicle is stored in a storage rack that has a relatively small transport distance from a loading port for loading via a single storage rack to a transfer port for loading and unloading. Is stored in a relatively large storage shelf.

Further, for the second purpose, a plurality of storage shelves at positions where the transport distance is relatively small are defined as storage areas for heavy vehicles, and the heavy vehicles are stored in the storage shelves in the storage area of the heavy vehicles. However, the lightweight vehicle is to be stored in a storage shelf outside the storage area of the heavy vehicle.

A third object is to increase or decrease the number of storage shelves in the storage area of the heavy vehicle according to the number of heavy vehicles that are expected to be parked within a predetermined period.

Whether or not the vehicle is a heavy vehicle is determined by a visual instruction from a manager or by measurement. As the measuring means, a weight scale installed on the cross section of the entrance path to the entrance or the entrance lifter or the like, or by the load of the driving machine when raising the lifter is used. Further, since a heavy vehicle is generally high in height or long in length, a vehicle having a height or a length not less than a predetermined value may be recognized as a heavy vehicle.

[Action]

The electric power consumption of the conveyance means that carries the vehicle is determined by the amount of travel, the amount of elevation, and the weight of the vehicle. For this reason, the power consumption can be reduced by reducing the transport distance including the traveling amount and the lifting amount.

According to the present invention, the heavy vehicle is stored in the storage rack that can reduce the transport distance, and the light vehicle is stored in the storage rack that has a relatively large transport distance. Therefore, the power consumption can be reduced.

According to the means for the second purpose, since the storage rack for a predetermined number of heavy vehicles is secured, the heavy vehicles are not transported in the transport distance unless the light vehicles are stored in the storage area for the heavy vehicles. It can be stored in a short storage area.

According to the means for the third object, when the expected value of the number of heavy vehicles is small, the storage area of the heavy vehicles becomes small, so that the transportation distance of the lightweight vehicles also becomes small and the electric energy of the transportation means is further reduced. It is possible.

〔Example〕

The present invention will be described below with reference to an embodiment shown in FIGS. In this embodiment, the entrance and the exit are combined.
In addition, a storage shelf is provided above the traveling path of the vehicle. Also, the vehicle is placed on a pallet for storage.

1 to 3, a shelf group 10 having a large number of storage shelves 10
Is mounted on a floor 12 installed above the traveling path of the vehicle 1. In addition, a stacker crane 15 that travels along the shelves 10
Runs over the floor 12. The stacker crane 15 is known as a transportation means. Below the shelving group 10, there is an entrance / exit 20. The loading / unloading port 20 is installed at the center of the rack group 10 in the traveling direction of the stacker crane 15. The entrance / exit 20 is surrounded by a fence 27. The rear surface of the entrance / exit port 20 in the traveling direction of the vehicle 1 is connected to the approach path 23 via the entrance gate 22.
The entire surface is connected to the exit 25 through the exit gate 24.
The entrance gate 22 and the exit gate 24 are opened by rising. Other doors for the driver are appropriately provided on the fence.

Place the pallet 5 in the loading / unloading port 20 and the shelves 10 and loading / unloading port.
A lifter 30 that moves up and down between 20 and 20 is provided. On the upper surface of the lifter 30, there is provided a conveyor 31 that conveys the pallet 5 in the traveling direction of the stacker crane. The lifter 30 can be raised from below the shelf group 10 to the height of the first-stage storage shelf 10a. The two storage shelves 10b, 10c on the left side of the storage shelves 10a are provided with conveyors 35, 36 for carrying the vehicle-mounted pallet 5. The in-vehicle pallet 5 to be stored is stored on the shelves by the conveyors 31, 35, 36.
It is transported from 10a to storage shelves 10b and 10c. The on-vehicle pallet 5 to be unloaded is transported in the opposite direction. The stacker crane 15 transfers the vehicle-mounted pallet 5 to or from any of the storage shelves 10a, 10b, 10c (conveyors 31, 35, 36). Storage shelves 10a, 10
Reference numerals b and 10c denote transfer ports for the stacker crane 15, which serve as base points for transporting the vehicle-mounted pallet 5. The stacker crane 15 includes a fork on which the on-vehicle pallet 5 is placed and moves toward the storage rack, an elevator for raising and lowering the fork, and a traveling body for moving the elevator along the rack group.

A pallet magazine 38 is installed on the storage shelf on the right side of the storage shelf 10a. Pallet magazine 38 raised conveyor 31
The empty pallet 5 is supplied to or the empty pallet 5 on the conveyor 31 is collected.

There are shelving groups 10 and 10 on both sides of the traveling path of the stacker crane 15, and loading / unloading ports 20 and 20 are arranged in the shelving groups 10 and 10, respectively.

Shelf group 10, stacker crane 15 and loading / unloading port 2 explained above
The configurations and operations of 0, the lifter 30, the conveyors 35 and 36, and the pallet magazine 38 are known. The instructions for warehousing and unloading by the driver of the vehicle are known.

The entry / exit gate 22 of the entry / exit port 20 is designed to open after confirming that a vehicle is present in front of the entry / exit port 20 of its own. Therefore, the vehicle desiring to park is temporarily stopped before the entrance gate 22. A weight scale 40 is installed on the road surface at this stop position. The weight scale 40 only needs to be able to determine whether the vehicle is a heavy vehicle or a light vehicle. That is, the scale 40 may be a switch.

In addition, a weight input device is installed near the entrance gate of the entrance / exit port 20.
45 have been installed. This is a switch that the manager operates when he or she certifies it as a heavy vehicle. When the command of the input device 45 indicates that the vehicle is a heavy vehicle, the command of the weighing scale 40 has priority.

At the position of the input device 45, a device (not shown) for a manager to operate the entrance gate 22 and to issue a parking card is installed. In addition, although a device for instructing the delivery is installed near the delivery gate, it is not shown.

In FIG. 1, the line K ₁ indicates the boundary between the storage area for heavy vehicles and the storage area for lightweight vehicles. Storage area for heavy vehicles is line K ₁
It is an area closer to the inner side, that is, closer to the transfer ports 10a, 10b, 10c. The storage area for a lightweight vehicle is the storage shelf outside the line K ₁ . The shelving groups 10, 10 on both sides of the stacker crane 15 similarly set storage areas for heavy vehicles.

The size of the storage area of the heavy vehicle (that is, the number of storage shelves for the heavy vehicle) is determined by the ratio of the heavy vehicle to the vehicles expected to be used.

If the command from the weighing scale 40 or the input device 45 is a heavy vehicle, it is stored in the storage area of the heavy vehicle. If it is a lightweight vehicle, store it in the storage area of the lightweight vehicle. In this way, when all the vehicles are stored in the storage shelves in one storage area, they are stored in the other storage area.

The number of vehicles using the parking lot varies greatly depending on the day of the week, the time of day, the weather, etc. For example, in the case of a parking lot attached to a store, the number of parking lots is large on Sundays, Saturdays, public holidays, public holidays, special sale days, and event dates. Also, it is small in case of rain. Also, it is low in the morning and before closing.

For this reason, if the boundary line K ₁ is determined from the number of storage shelves in the shelving group 10 and the proportion occupied by heavy vehicles, if the boundary of the parking lot is small (i.e., the vehicle is used) on a day or time when there are few users. In this case, even if the storage area for the heavy vehicle is empty, the light vehicle is stored in the storage shelf located far away from the transfer ports 10a to 10c.

Therefore, if the storage area for heavy vehicles is increased or decreased in anticipation of the number of vehicles used, the amount of electric power can be further reduced. The line K _{2 in} FIG. 1 indicates the outer edge of the storage area of the heavy vehicle when it is determined that the number of users is small.

In FIG. 4, reference numeral 50 is a control device that determines a storage shelf in which a vehicle is to be stored, and is composed of a computer. The control device 50 is a setting means 51 for setting the storage area (storage shelf) of the heavy vehicle.
From storage shelf determining means 52 for determining a storage shelf for storing the vehicle for which a storage request has been made, storage area 55 for the heavy vehicle, and storage means 55 for storing the storage shelf for storing the vehicle. It is configured.

When a storage request is made, the storage shelf determination means 52 determines the storage shelf based on the data in the storage means 55 and the vehicle weight data. This determined storage shelf is output to the stacker crane 15.
59 as well as stored in the storage means 55. The stacker crane 15 thus stores the vehicle.

The weighing scale 40 and the weight input device 45 are input to the storage rack determining means 52. When the data of the weight input device 45 indicates that the vehicle is a heavy vehicle, the data of the input device 45 has priority over the data of the weighing scale 40.

The calendar (6
1), time (62), special day (63), weather (64) data and operation mode (65), input device 61,62,63,64, setting device 65
Enter with.

The data of the calendar (61) consists of data of days, days of the week, and holidays. Many vehicles are used on Saturdays, Sundays, and holidays.
In addition, the number of cars used also changes depending on the season.

The data at time (62) is the current time. There are few cars in the parking lot attached to the store in the morning and many in the afternoon.
If it is further subdivided in the morning and afternoon, the number of parking lots will differ depending on the time of day.

The special day (63) data is input by the manager. A special day is a day on which it is expected that the number of vehicles used in the parking lot on the day will be higher (or particularly lower) than usual. If you
In the parking lot attached to the store, it is expected that the number of vehicles used will be larger than usual days, such as special sale days and event dates. If the date falls under this, the administrator will enter it.

The weather (64) data is input when it is expected that the number of users will be small, such as in the case of rain or stormy weather. This is entered by the manager.

The setting means 51 obtains the number of users for each time zone based on the data of the calendar (61), the time (62), the special day (63), and the weather (64), and sets the storage area for the heavy vehicle. Therefore, the storage area of the heavy vehicle changes for each time period.

The number of vehicles used, that is, the number of heavy vehicles can be calculated, for example, by factoring the day of the week, the time, the special day, and the weather. When calculating the number of vehicles used, refer to the average parking time calculated empirically. The closing time of the store,
Alternatively, as the parking time approaches the closing time, the number of vehicles that desire new parking decreases. Therefore, the storage area for the heavy vehicle is not set in the time zone immediately before the store is closed, and the light vehicle is also stored in the storage area for the previous heavy vehicle. According to this
The amount of power can be further reduced. Further, even when the number of users is small, such as when the store is closed, it may be better not to set the storage area for the heavy vehicle.

Special day (63) data and weather (64) data are input from the terminal in the control room.

The above is an example of automatically calculating the number of vehicles used, that is, the number of heavy vehicles, but may be manually set. The mode setter 65 is provided for this purpose, and the manager sets the number of vehicles used (that is, the number of heavy vehicles) for each time period for each day. Input is done by operating the terminal in the control room. As for the input method, the number of vehicles or heavy vehicles may be input, or the rank such as A, B, C may be input. When entering the rank, the number of heavy vehicles is determined according to the rank. Further, the mode setter 65 can set a time zone in which the storage area of the heavy vehicle is not set. It can be input from the mode setting device 65 at any time, and the storage area of the heavy vehicle can be changed at any time.

The command of the mode setter 65 has priority over the case of the vehicle calculation.

The operation of this configuration will be described with reference to FIG. If there is an empty shelf that can be stored in the storage shelf, the storage gate 22 opens and storage is permitted. At this time, the weight of the vehicle is measured by the weight scale 40. In the case of a time zone in which a storage shelf is determined according to the weight of the vehicle (a time zone for division), the limiting device 50 is a weight scale 40.
Also, it is determined whether the vehicle is a heavy vehicle based on the data of the weight input device 45. (Steps S10, S20) If it is a heavy vehicle, it is determined whether or not there is an empty column in the storage area of the heavy vehicle, and if there is an empty shelf, one of the empty shelves is output to the stacker crane 15. (Steps S30 and S40) If there is no empty shelf in the storage area of the heavy vehicle, the process proceeds to step S60.

On the other hand, in the case of a lightweight vehicle, it is determined whether or not there is an empty shelf in the storage area of the lightweight vehicle, and if there is an empty shelf, one of the empty shelves is output to the stack crane 15 (steps S50, S6).
0). If there are no empty shelves in the storage area of the lightweight car, step S
Move to 40. In the case of a time zone where division is not necessary, the process proceeds to step S30, and it is checked whether or not there are empty shelves in the storage shelves near the transfer ports 10a to 10c.

Power consumption for both loading and unloading by the stacker crane and lifting / lowering of the stacker crane are used to expand the storage area of the heavy vehicle in an arc shape, the vertical direction, or the horizontal direction around the transfer ports 10a to 10c. It is determined by comprehensively determining the recovered power when the platform is lowered, and the loading and unloading time of the stacker crane.

A case where one stacker crane has two sets of forks and simultaneously carries two vehicle-mounted pallets will be described. In the case where two vehicles desired to be stored are simultaneously transported by the stacker crane and one vehicle is a heavy vehicle and the other is a lightweight vehicle, it is preferable to store each vehicle in each area. In this case, it is preferable to store the heavy vehicle first and then store the light vehicle. In addition, if the aim is to further reduce the time required for warehousing,
Store heavy and light vehicles in the heavy vehicle storage area. In this case, the storage area for the heavy vehicle is set large.

When two vehicles are to be unloaded at one time, when one vehicle is stored in the storage area for heavy vehicles and the other vehicle is stored in the storage area for lightweight vehicles, the stacker crane is loaded first with the lightweight vehicle first. Then, the heavy vehicle is then placed on the stacker crane, and the stackers are simultaneously delivered to the transfer ports 10a to 10c.

In the above embodiment, the weight scale 40 is installed in the approach passage 23,
It may be installed on the lifter 30. Further, whether or not the vehicle is a heavy vehicle may be determined by the force required to lift the lifter 30. It is also possible to install a height meter or a length meter of the vehicle on the approach road or the like, and determine that the vehicle having a predetermined height or more or a predetermined length or more is a heavy vehicle.

In the above embodiment, there are two stages, a heavy vehicle and a light vehicle, but it may be divided into a plurality of stages.

In the embodiment of FIG. 6, the entrance 20a is at one end of the shelf group 10,
This is the case where the exit port 20b is at the other end of the shelf group 10. The transfer port for the stacker crane 15 is the same as the storage port 20a and the storage port 20b. The entrance (transfer entrance for warehousing) 20a and the exit (transfer entrance for unloading) 20b are at the same height. In this case, the storage area of the heavy vehicle is based on the lower storage rack (the first storage rack from the bottom) between the loading transfer port 20a and the shipping port (transfer port for shipping) 20b. Expand upwards.

〔The invention's effect〕

As described above, according to the present invention, since the transport distance of the transport means by the transport means can be shortened for the heavy vehicle, it is possible to reduce the total amount of operating electric power.
