[0011]

In such a mechanical parking lot, a large number of vehicles are stored in different shapes according to the standard of each vehicle type. For example, medium-sized vehicles, which are called medium-sized vehicles, have large lengths, widths, and heights that are large, light vehicles that have small displacement and low displacement, and high-roof vehicles that have a particularly high vehicle height. Is mentioned. Further, in the mechanical parking lot, in order to satisfy the storage request from the user, it is necessary to store and store at least the general vehicles described above, and it is necessary to maintain the storage rack.

In order to store all of the above-mentioned vehicles, it is possible to form a storage rack corresponding to the largest vehicle and combine it with a plurality of storage shelves. According to this, since it can be configured as a unified storage rack, it is possible to share various parts.

However, depending on the location where the mechanical parking lot is installed, the installation of the same storage shelves is not always possible due to the existence of facilities such as columns and pipes.
Therefore, it is necessary to solve how to effectively use the dead space.

Further, there is a problem in that a wasteful space is created by installing a storage shelf corresponding to any vehicle shape. More specifically, by describing an example, when a light vehicle is stored in a large storage shelf, the volume occupied by the light vehicle becomes extremely smaller than the storage capacity of the storage shelf. As a result, the use state of the storage shelves becomes inefficient, and as a result, the number of storage shelves installed in the mechanical parking lot where the installation space is restricted may decrease and the storage capacity may decrease. On the other hand, on the other hand, the mechanical parking lot may become large in size.

The present invention has been made in view of the above circumstances, improves the storage capacity of a mechanical parking lot, and further facilitates the operation of the mechanical parking lot related to the storage of the vehicle to improve the storage efficiency. An object of the present invention is to provide an improved mechanical parking lot and a control method thereof.

[0016]

In order to solve the above problems, the present invention adopts the following means. The invention according to claim 1 is a loading / unloading berth for loading / unloading a vehicle, a plurality of storage shelves for storing the vehicle, and a carrier device for transporting the vehicle between the loading / unloading berth and each of the storage shelves. In the mechanical parking lot including the above, each of the storage shelves is formed in a different shape according to the shape of the vehicle.

That is, the storage shelves are not all provided in the same shape, and for example, storage shelves for large vehicles, storage shelves for light vehicles, etc. are formed, and the storage shelves of these different shapes are formed. Will be provided in combination. Even when the storage shelves having the same shape cannot be formed due to the restrictions such as the space at the time of installation, the storage shelves are formed and provided by avoiding the restrictions. Therefore, when various vehicles are stored, useless empty space in each storage rack is eliminated, and a plurality of storage racks are functionally configured and provided.

According to a second aspect of the present invention, in the mechanical parking lot according to the first aspect, parts of the storage shelves having the same shape are arranged in a double row so as to be adjacent to each other. It has a feature.

By arranging storage shelves of the same shape so as to be adjacent to each other, more storage shelves are provided,
In addition, the movement of the vehicle on both storage shelves can be performed reliably and efficiently.

According to a third aspect of the present invention, in the mechanical parking lot according to the first or second aspect, the control device for controlling the operation of the carrier device and each of the storage shelves is provided with a stored vehicle. It is characterized in that a load alignment control unit for instructing transfer to a storage shelf suitable for the shape of the vehicle is provided.

Since the storage shelves are formed in different shapes according to various vehicle shapes, small vehicles may be stored in the large storage shelves. However, in the above case, the storage shelves are inefficiently used. Therefore, in order to avoid this problem, the load-alignment control unit provided in the control device stores the vehicle once stored in the storage device suitable for this vehicle shape. Prompt for instructions to transfer to a shelf. This may, for example, be the case when the vehicle is stored in a storage shelf that does not conform to the vehicle shape because the storage operation is completed immediately or there is no empty storage shelf that is suitable for the storage vehicle at the time of storage. Even if the storage shelves are once stored, the storage shelves are transferred to an appropriate storage shelves to improve the efficiency of use of the storage shelves.

According to a fourth aspect of the present invention, in the mechanical parking lot according to the second or third aspect, the control device for controlling the operation of the carrier device and each of the storage shelves is arranged in a double row. A loading control unit is provided for instructing transfer of a vehicle on the front side to a storage shelf suitable for the shape of the vehicle based on a leaving command of a vehicle on the back side of the storage shelf.

When a vehicle output command is issued to a vehicle on the back side of the storage shelves arranged in double rows, the vehicle stored on the front side interferes with the vehicle leaving the vehicle. When the vehicle is moved, a storage shelf suitable for the shape of the vehicle is selected as a destination of the front vehicle, and an instruction to move the front vehicle to the selected storage shelf is prompted. In other words, the cargo handling control unit carries out the cargo alignment work for transferring the vehicle, which is an obstacle when the shipping work is started, to an appropriate storage rack.

According to a fifth aspect of the present invention, in the mechanical parking lot according to any one of the first to fourth aspects, at least one of the plurality of storage shelves serves as a vehicle maneuvering place when the vehicle is transferred. It is characterized as a shared shelf that functions.

The shared shelf is a place for temporarily evacuating and storing a vehicle which hinders the operation when, for example, arranging or carrying out cargo of vehicles, and has a function as a normal storage shelf. It is a storage shelf that is in an empty state so that the vehicle can be operated. As a result, even if all the storage shelves are stored, a vehicle evacuation location for the load alignment and cargo handling work can be secured. The shared shelf is not limited to a specific storage shelf, and the functional position may change from moment to moment. Further, they may be provided according to the type of storage shelves.

According to a sixth aspect of the present invention, in the mechanical parking lot according to the fifth aspect, the shared shelf is formed to have a shape capable of being stored in any of the vehicles to be stored. It is characterized by being.

Since the shared shelves have the shape of storage shelves that can accommodate all of the vehicles that enter, no matter what kind of vehicle shape the vehicles that interfere with the operation of the mechanical parking lot,
It will be temporarily evacuated by at least one shared shelf.

According to a seventh aspect of the present invention, a loading / unloading berth for loading and unloading a vehicle, a plurality of storage shelves formed in different shapes to store the vehicle, the loading / unloading berth and each of the storage shelves. In a method of controlling a mechanical parking lot including a transport device for transporting a vehicle between and, while storing a vehicle to be stored in any of the storage shelves capable of storing,
It is characterized in that the stored vehicle is transferred to a storage rack suitable for the shape of the vehicle as needed.

By using such a mechanical parking lot control method, the stored vehicle is appropriately stored in a storage shelf suitable for the shape of the vehicle.

Further, a delivery berth (not shown) is provided near the delivery berth on the traveling path 12, and a delivery lifter 5 (transport device) is further provided adjacent to the delivery berth.

Each of the plurality of storage shelves 6 having different sizes is combined at each position. In the figure, the storage shelves 6 are located in the space of the second basement floor (B2FL).
It is equipped with a step arrangement. The storage shelves 6 will be further described. The storage shelves 6 shown in FIG.
There are types (6a to 6f), and these are formed in a shape that does not generate an extra space according to the shape of various vehicles to be stored. In other words, the storage shelves 6 of different shapes are combined in consideration of the installation space of the mechanical parking lot and the entrance to the road adjacent to the mechanical parking lot. And, on the floor surface of each of these storage shelves 6a ...
A slat conveyor 9 (transport device) corresponding to each wheel base of each vehicle is provided.

The medium-sized storage shelves 6a, which occupy a large proportion of the large number of storage shelves 6, are the external dimensions of a medium-sized vehicle 1a (generally called a "normal passenger car") which is generally called a 5 number size. It is formed in a shape corresponding to, and is provided mainly at the first stage and the second stage.

The medium-sized H storage rack 6b is used for the medium-sized vehicle 1
It is formed in a shape corresponding to the external size of the vehicle 6b so that the medium size vehicle 1b having the same length and width as that of a and having a large height dimension can be stored. The storage rack 6b for medium-sized H as described above is provided at the third stage of the storage rack for medium-sized storage which mainly has a margin in height with the ceiling. In addition, as shown in the figure, since the height of the ceiling becomes low at the place where the pipe P, the electric wiring W, and other ducts are arranged on the ceiling, it originally functions as the storage rack 6b for medium-sized H. One is provided as a medium-sized storage shelf 6a that cannot be applied to the high-roof type vehicle 1b.

Further, in the drawing, 1, near the delivery lifter 5,
A large-sized storage shelf 6c is provided in the second stage. The large-sized storage rack 6c is formed to have a large size in accordance with the external dimensions of the large-sized vehicle 1c (large-sized passenger vehicle) generally called a 3 number size. Then, a large H storage rack 6d capable of storing a high-roof type large vehicle (not shown) is formed and provided on the third stage, which is the upper side of the large storage rack 6c.

Further, on the right side of the figure, a light vehicle 1e is provided.
The light storage shelves 6e for storing are provided in the first and second stages. The third-tier is provided with a light H storage rack 6f for storing a high-roof type light vehicle (not shown). The light storage shelves 6e and the light H storage shelves 6f are formed such that their longitudinal dimensions are shorter than the other storage shelves in accordance with the standards of light vehicles.

As described above, a large number of storage shelves 6a ... Having different shapes are installed by appropriately determining the number according to the operating environment in which they are used, and the pipes P and the electric wiring W. In addition, the installation area of the pillars and the installation area of the mechanical parking lot will be taken into consideration so that no extra space will be created. In addition, although the storage shelves 6 are provided in a single row for the purpose of cross-section in this figure, a large number of storage shelves 6 are provided across the lane along which the carriage moves, and depending on the location, the storage shelves may be adjacent to each other. It is equipped with a double-row storage rack installed at.

The type of each storage rack will be further described with reference to FIG. 2. The light storage rack 6f is a small storage rack for storing general light vehicles other than high roof type light vehicles. It is said that it cannot store a vehicle larger than a light vehicle. A small-sized storage rack (not shown in FIG. 1) is a storage rack for a small vehicle called a small car or a liter car with a displacement of about 1 liter, the number of which has been increasing in recent years, and is smaller than a small vehicle. It is also possible to store the light vehicle 1e as required.

The medium-sized storage rack 6a can store the medium-sized vehicle 1a as described above, and can store the light vehicles 1e and small vehicles which are smaller than the medium-sized vehicle 1a as required. Has been done. The large storage shelf 6c can store the large vehicle 1c as described above,
Smaller vehicles such as medium-sized vehicles 1a and the like can be stored as needed.

The outside large-sized storage shelf (not shown in FIG. 1) is
A large vehicle 1c that is a smaller vehicle that can store a larger large vehicle that complies with European and American standards.
Alternatively, the medium-sized vehicle 1a and the like can be stored as needed.

The symbol H of the light H storage rack 6f, the small H storage rack (not shown in FIG. 1), the medium H storage rack 6b, and the large H storage rack 6d has a relatively high vehicle height. It refers to a shaped high roof type. Each of these storage shelves (6
b, 6d, 6f, etc.) are various high roof type vehicles (1b
It is possible to store a vehicle having a lower height than that as well as a vehicle having a shape corresponding to (1). In addition, as the storage shelves formed as other types, there may be a case where a storage shelf that stores vehicles other than the above and equipment vehicles is provided.

Now, in the mechanical parking lot provided with the storage shelves 6 having different shapes as described above, it is determined whether the storage shelves 6 are in an operating state, that is, whether the storage shelves are empty or storing vehicles. While recognizing, a control device for controlling the operation of the mechanical parking lot by controlling the operations of the lifters 4 and 5 which are the transporting devices is provided. The configuration and operation of this control device will be described below with reference to FIG.

FIG. 3 is a diagram for explaining the control circuit of the mechanical parking lot. The control device 20 shown in this figure includes at least the lifters 4 and 5, the carriage 7, and the slat conveyor 8 (see FIG. 1).
It includes slat conveyors 2a, 3a, 4a, 5a and 9 shown in FIG. ) And the like, and an operation control section 21 for controlling the operation of each transport device, and a storage shelf selection section 22 for selecting the storage shelf 6 to be used when the vehicle is loaded or transferred. In addition, the storage shelf selection unit 22 is provided with a load alignment control unit 22a and a load handling control unit 22b that give instructions to transfer the stored vehicles. The load here refers to the vehicle.

As shown in the figure, the control device 20 receives information on the operating state related to the storage of the vehicle from each storage rack 6, and the storage obtained by the card reader 10, the settlement machine 11, etc. Information related to shipping and shipping has been entered. Further, the control device 20 inputs information on the operating state from the lifters 4 and 5, the carriage 7, the slat conveyor 8 and the like, and a signal for control based on the input information is input from the operation control unit 21 to the lifters 4 and 4. 5 is output to a carrier device.

An address for identifying each storage rack 6 is assigned to each storage rack 6, and a priority number that functions as a priority order for storing is assigned according to the operation of the mechanical parking lot. ing. This priority number is properly considered and functions when selecting a storage shelf to be described below.

As shown in the figure, when an instruction to store a vehicle is input from the card reader 10 to the control device 20, the control device 20 inputs the vehicle storage command from the card reader 10, the settlement machine 11, the storage shelves 6 and the like. The operation information of each storage shelf 6 is fetched and sent to the storage shelf selection unit 22. At the same time, the control device 20 selects the cart 7 to be used.

In the storage shelf selection section 22, the storage shelf 6 to be selected is selected.
A plurality of selection modes for changing the storage rack 6 according to the operating state of the mechanical parking lot are prepared, and the operation information of each storage rack 6 described above is processed by any of these selection modes to store the storage rack 6 Is selected. In addition, each selection mode corresponds to the touch panel 10 provided in the card reader 10.
It can be changed with a, etc.

Further, in the selection of the storage shelves 6 which is the basis of each selection mode described below, the storage shelves 6 suitable for the vehicle shape of the entering vehicle are selected while considering the priority number described above. In addition, with respect to the storage shelves 6 having a plurality of rows, priority is given to selection of the front storage shelves 6 adjacent to the carriage 7.

However, in the operation of the mechanical parking lot, such a selection of the storage shelves 6 is not always executed, and for example, a small vehicle can be stored in the large storage shelves 6c for quick warehousing work. Needed to do. This also reduces the storage efficiency. Therefore, in each selection mode, and in the load alignment control unit 22a and the load handling control unit 22b related to each selection mode, this problem is appropriately solved to optimize the operation. I am trying.

An example of each selection mode will be given below.
Specific operations of the warehousing work and warehousing work of the vehicle will be described with reference to the drawings. First, the delivery priority mode will be described as the first selection mode. In the shipping priority mode, when the storage shelves 6 are arranged in multiple rows as shown in FIGS. 4 and 5, the empty storage shelves 6 adjacent to the carriage 7 are preferentially selected, and then the carriage 7 is selected. When all the adjacent storage shelves 6 are used, thereafter, the operation is controlled so that the back side of the storage shelves 6 that are arranged in multiple rows (the storage shelves separated from the carriage 7) are used as appropriate. That is, when a certain number or more are stored, priority is not given to selecting the storage shelves 6 according to the shape of the vehicle but to speeding up the delivery operation.

In FIG. 4, among the storage shelves 6 on the front side adjacent to the truck 7, the storage shelves 6A for medium sized vehicles suitable for the medium sized vehicles (1a-En) to be stored are selected.

Further, as shown in FIG. 5, when an issue command is issued to the medium-sized vehicle (1a-Ex) stored in the rear-side medium-sized storage rack 6a, the medium-sized vehicle (1a-Ob) on the front side is moved. Since the items need to be transferred, the cargo handling control unit 22b starts searching the storage rack 6 to which the vehicle (1a-Ob) should be moved.

The cargo handling control section 22 in the shipping priority mode
In the search of the storage shelf 6 in b, first, an empty storage shelf 6 adjacent to the carriage 7 is searched. This is possible when a vacancy occurs due to another vehicle leaving before that time. In addition, the storage shelves 6 that correspond to the above search
When there are many storage shelves 6, which is suitable for the vehicle shape,
Further, the storage rack 6 located at the closest position among them is selected. Furthermore, the storage rack 6 suitable for the vehicle shape is sequentially selected as the destination by prioritizing the predefined adaptation order of the vehicle and the storage rack, that is, the vehicle having a shape close to the storage rack 6.

Then, if the storage shelves 6 of the moving destination are not found in the above, or if the storage shelves 6 to be opened are unloaded.
In the case of returning to A, the cargo handling control unit 22b uses the shared shelf 6
Select x as the destination.

When the vehicle is evacuated to the shared shelf 6x due to the unloading work, the dolly 7 that has finished the leaving work moves toward the shared shelf 6x again, and removes the vehicle that has prevented the leaving from the shared shelf 6x.
Transfer to a storage shelf 6A other than x or another storage shelf 6 This work is to keep the shared shelf 6x always empty.

Even if all the other storage shelves 6 are stored in the shared shelf 6x, one shelf is always prepared for the evacuation of the load arrangement and the cargo handling work, regardless of the vehicle to be stored. It is formed to have a shape that allows it to be stored. For this reason, when the storage shelves 6 are all filled except for the shared shelves 6x, when the shared shelves 6x are selected as the evacuation location by the load alignment and cargo handling work from the storage shelves that are slightly smaller than the shape of the shared shelves 6x. In this case, as described above, the operation of exchanging vehicles that are commonly used is performed after the work of aligning and carrying out the work.
However, even in the case described above, if the storage shelf that has been delivered has the same maximum shape as the shared shelf 6x, a new space for this storage shelf is newly secured by delivery, so this storage shelf 6 is selected and the original storage shelf is selected. Do not return to the position.

If there is an empty storage shelf 6 other than the common shelf 6x, even if the storage shelf 6 is not suitable for the shape of the vehicle, this storage shelf 6 is selected and the original position is restored. Do not do work to return to.

The cargo handling control section 22b outputs the result to the operation control section 21 when the storage rack 6 is selected by the above-described search. Then, the medium-sized vehicle (1
(a-Ex), the dolly 7 arrives at the storage shelf 6 having a-Ex), and the slat conveyor is driven to drive each vehicle (1a-Ex,
1a-Ob) is carried to the dolly 7 side. Then, the medium-sized vehicle (1a-Ob) that interferes with the delivery is placed on the carriage 7 and transported to the selected storage shelf 6 or the shared shelf 6x.
At this point, a medium-sized vehicle (1a-Ex) scheduled to leave
Stands by at the medium-sized storage shelf 6A on the side adjacent to the carriage 7.

Medium-sized vehicles (1a-Ob) that hinder the delivery of goods
The dolly 7 that has finished transferring the items to the shared shelf 6x has a medium-sized storage shelf 6A that has the medium-sized vehicle (1a-Ex) that is the object of leaving again.
When the medium-sized vehicle (1a-Ex) is loaded by the operation of the slat conveyor, the medium-sized vehicle (1a-Ex) is conveyed to the delivery lifter 5 to complete the delivery operation.

As described above, in the shipping priority mode, the storage shelves 6 suitable for the vehicle are basically selected, but the storage shelves necessary for the transfer can be shortened so that the working time at the shipping can be shortened. 6 will be selected.

The storage efficiency priority mode will be described as the second selection mode. This storage efficiency priority mode preferentially selects an empty storage shelf 6 adjacent to the carriage 7 when the storage shelf 6 has a double row as shown in FIGS. 6 to 9. Moreover, the storage shelf 6 suitable for the shape of the vehicle to be stored is preferentially selected by transferring at the time of loading and unloading to improve the storage efficiency of the mechanical parking lot.

First, referring to FIG. 6, the vehicle (1a-En) stored by the storage lifter 4 is prioritized by the storage shelf selection unit 22 which has acquired the information on the vehicle shape detected at the storage berth. The storage shelf 6 suitable for storage is selected while considering the number.

Explaining this more concretely, the first condition which is prioritized as the condition to be selected is the vehicle to be stored in the storage rack 6 which is open in the front side in the storage racks 6 which are double rows. The storage shelf 6 having a shape suitable for is selected. Here, as shown in FIG. 6, if there is no vacancy in the storage shelf 6 on the front side except the shared shelf 6x, the medium-sized vehicle (1a-
En) selects the medium-sized storage rack 6A suitable for the vehicle shape in which no vehicle exists on the back side, which is the second priority condition. In other words, each of the medium-sized vehicles (1a, 1a-) that matches the shape of both of the double-rowed medium-sized storage shelves 6a, 6A.
En) will be stored.

Further, as shown in FIG. 7, when the medium-sized vehicle (1a-Ob) is stored in the large-sized storage rack 6C capable of storing the stored large-sized vehicle (1c-En), the vehicle (1a- Ob) is transferred to the medium-sized storage rack 6A suitable for this shape, and the load-alignment control unit 22b operates so as to store the large vehicle (1c-En) in the large-scale storage rack 6C that has become empty due to the transfer. It issues an instruction to the control unit 21. The transfer of each vehicle described above can be performed even when the vehicle to be stored has not arrived.

Further, as shown in FIG. 8, when a large-sized vehicle (1c-Ex) on the back side receives a leaving command, the cargo handling control section 22b causes the medium-sized vehicle (1a) on the front side to prevent the leaving. -Ob) is urged to transfer to the medium-sized storage rack 6A suitable for this vehicle shape. As a result, the medium-sized vehicle (1a-Ob), which becomes a hindrance when the large-sized vehicle (1c-En) on the back side is unloaded, is stored in the medium-sized storage shelf 6A suitable for the vehicle shape, and each storage is performed. The utilization of the shelves 6 is optimized.

Further, in FIG. 9, when a large vehicle (1c-Ex) on the front side is issued a leaving command, the large vehicle (1c-Ex) is unloaded normally, and the load alignment control section 22a is also operated. Prompts an instruction to transfer a medium-sized vehicle (1a-Ob) not suitable for the large-sized storage rack 6c on the back side to the storage rack 6A suitable for the vehicle shape.
This is done by utilizing the fact that the large vehicle (1c-Ex) leaving the warehouse is sent to the dolly 7 by the slat conveyor and at the same time the medium-sized vehicle (1a-Ob) on the back side is carried to the dolly 7 side. Is.

In this case, since the medium-sized vehicle (1a-Ob) is located on the large-scale storage rack 6c on the front side, the vehicle (1a-
Although it is in a state where it can be easily carried out if the delivery of Ob) is completed, the storage efficiency is lowered because the large-sized storage rack 6c that can cope with many vehicle shapes is used. In order to avoid this, the load alignment control unit 22a prompts an instruction to store the medium-sized vehicles 1a and 1a-Ob in both of the double-rowed medium-sized storage shelves 6.

As described above, the load-alignment control section 22a that functions in each selection mode works to store each vehicle in each storage rack 6 suitable for the vehicle shape of each vehicle. In addition, the cargo handling control unit 22b gives an instruction to transfer a vehicle that is an obstacle when the double-rowed vehicle on the back side is unloaded, and stores the storage rack 6 suitable for the vehicle shape in response to a request to increase storage efficiency. You will be prompted to move the vehicle to.

As a result, the storage shelves provided in the mechanical parking lot in different shapes can be effectively used, the operation of the mechanical parking lot relating to the storage of the vehicle is facilitated, and the storage efficiency is improved. It is possible to plan. Further, by the configuration of the mechanical parking lot including the storage shelves provided in different shapes described above, while efficiently storing more vehicles,
