Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking position detecting device for a parking facility, and more particularly to a parking position detecting device for a parking facility for parking a vehicle at predetermined intervals.

[0002]

2. Description of the Related Art Conventional parking equipment includes a mechanical parking equipment that is placed on a pallet and is transported to a parking space. The pallet itself has a transport means, or a pallet without a transport means is separated from the pallet. There are various types such as those that are transported by the transporting means.

In addition, the parking facility is provided with a storage room for loading vehicles into the pallets. Various detecting devices are provided in the storage room, and for example, Japanese Patent Laid-Open No. 4-115067.
As disclosed in the publication, a detection device for selecting a vehicle of a length that can be parked in the parking device is provided. In the detection device, a plurality of vehicle length calculation means are arranged in the storage room in the vehicle length direction (see FIGS. 1 and 3 of the same publication), and the vehicle length calculation means detects the vehicle length to detect the vehicle length. A long signal is output, and based on the vehicle length signal, it is determined whether or not the length of the vehicle is less than or equal to the maximum vehicle length at which the vehicle can be parked. If the vehicle length exceeds the maximum vehicle length, a message to that effect is displayed on the guide display board. It is displayed so as not to be stored, and when the vehicle length is less than the maximum vehicle length, it is stored in the parking space in the parking facility. In this case, the parking space is usually set to a length that has a certain margin added to the maximum vehicle length.

Further, when parking a vehicle at a predetermined position in a parking space, the pallet is often positioned when the vehicle is loaded on the pallet. To this end, a parking position detecting device is provided in the warehousing room, and the parking position detecting device includes the vehicle length calculating means, and the front end position of the normal vehicle is used as a reference of the stop position to detect the front end of the vehicle by a sensor. The position is detected and the vehicle position in the pallet is regulated based on the front end position signal.

On the pallet, a pair of vehicle stoppers are arranged in front of and behind one wheel, but the installation position and the front and rear spacing of the pair of wheel stoppers are based on the front end position of the vehicle. The length is set in consideration of the size of the vehicle length, the type of vehicle (for example, the distance from the front end position to the front wheel for stopping the vehicle varies depending on the type of vehicle).

[0006]

However, the parking position detecting device for the parking facility described above only determines whether or not the vehicle entering the vehicle is less than or equal to the maximum vehicle length, and the vehicle entering the vehicle is less than or equal to the maximum vehicle length. If so, regardless of the length of the vehicle, it is stored in a parking space that allows for maximum vehicle length and room. Therefore, when a small vehicle having a small vehicle length is stored in the parking space, a useless space is generated. If the number of small vehicles stored in the vehicle increases, the amount of wasted space increases, and the vehicle storage efficiency deteriorates.

Further, in the above parking position detecting device, the stop position is regulated with reference to either the front end position or the rear end position of the vehicle, and the length of the pallet is set according to the vehicle having the maximum vehicle length. Therefore, in a small-sized vehicle, there is an inconvenience that the pallets are arranged at the front or rear of the pallet. Therefore, there is a problem that the load balance of the pallet becomes unbalanced, which hinders the transportation of the pallet. Further, if the stop position is regulated with reference to either one of the front and rear end positions of the vehicle, the positions of the wheels for stopping the wheels vary greatly between the large vehicle and the small vehicle, and the size of the vehicle is reduced. However, there is also a problem that the distance between the front and rear of the pair of wheel stoppers becomes very large in order to stop the wheel stoppers, and the effect of the wheel stoppers is diminished.

The present invention has been made in view of the above point, and enables the vehicle to be housed in a parking space of an appropriate size according to the length of the vehicle and is stopped at the center of the pallet. The purpose is to be able to.

[0009]

In order to achieve the above object, the present invention not only detects the length of a vehicle to determine whether or not the vehicle entering the vehicle is less than or equal to the maximum vehicle length, but also the detected vehicle. By calculating the parking range according to the length of the vehicle and determining whether or not the vehicle is accommodated in the parking range, it is possible to ensure that the vehicle is accommodated in the parking range of the length corresponding to that length. It is something to do.

Specifically, the solution means taken by the present invention is a parking position detection device for a parking facility, which has a plurality of vehicle detection sensors provided at predetermined intervals in the vehicle length direction, Vehicle front-and-rear end detecting means for detecting a front-end position and a rear-end position of the vehicle and outputting a position signal, and a vehicle length is calculated based on the position signal from the vehicle front-and-rear end detecting means and output as a vehicle-length signal. A vehicle length calculation means, a parking range calculation means for calculating a parking range in the vehicle length direction for accommodating a vehicle based on a vehicle length signal from the vehicle length calculation means, and outputting it as a parking range signal, and the parking range calculation means And a stop position determining means for determining whether or not the vehicle is accommodated in the parking range based on the parking range signal from the vehicle and the position signal from the vehicle front and rear end detecting means.

[0011]

With the above structure, in the present invention, the parking range calculating means calculates the parking range based on the vehicle length signal of the length of the vehicle, and the parking range corresponds to the length of the vehicle in the vehicle length direction. Will be set to. Based on the parking range signal and the position signal of the vehicle front and rear end detecting means, the stop position determining means determines whether or not the vehicle is accommodated in the parking range based on the parking range signal and the position signal.
It is possible to know whether the vehicle is reliably accommodated in the parking range according to the length of the vehicle. Therefore, the stop position of the vehicle with respect to the parking range can be easily known, and correction can be easily made when the stop position of the vehicle deviates from the parking range, and the vehicle can be reliably stored in the parking range of a length corresponding to the length. To be done.

Next, the detecting operation of the parking position detecting device E will be described.

For example, as shown in FIG. 2, the maximum vehicle length L ₁
When a large-sized vehicle enters the pallet 15, the photocells are blocked at the moment when the photocells are shielded from light and then passed through again.
,,,, are shielded from light, and only the photocell passes through,
The rear end position of the vehicle W is on the phototube, the front end position is between the phototubes, and the vehicle length calculation means B is
Is calculated as the maximum vehicle length L ₁ . After that, the parking range calculation means C sets the maximum vehicle length L ₁ in the parking range.

In the case of the maximum vehicle length L ₁ , the photocells and the photocells are located at the center of the pallet 15 at the maximum vehicle length L ₁
Since the front end position and the rear end position of the vehicle W when the vehicle W of FIG.
After the heavy vehicle of _{No. 1} is stopped, the stop position determination means D determines that the pallet 15 is accommodated in the parking range set in the center. Then, under the control of the controller 31, the pallet 15 is transported to the third stage, which has the parking space b for large vehicles.

When a small vehicle having a vehicle length smaller than the maximum vehicle length L ₁ enters the pallet 15, the photocells are shielded at the moment when the photocells are shielded from light and then passed through the pallet 15.
When the photocells are shielded and the phototubes are passing through, the rear end position of the vehicle W is located at the phototube and the front end position is between the phototube and the photocell, and the vehicle length calculation means B

After that, the parking range calculation means C sets the length L ₂ of the maximum vehicle W to the parking range.

Next, since the vehicle located between the photoelectric tubes is biased to the rear of the pallet 15, as shown in FIG. 3, the stop position determining means D causes the front end regulating photoelectric tube corresponding to the parking range L2. For example, a phototube is selected, and a phototube that is away from the phototube by a parking range L ₂ is selected as the photocathode for rear end regulation, and it is determined whether or not the vehicle W is stopped between the phototubes. Then, under the control of the controller 31, the pallet 15 is transported to the first stage or the second stage where the parking space c for a small vehicle is provided.

As described above, in the present invention, the parking range calculating means C calculates the parking range corresponding to the size of the vehicle W based on the vehicle length signal of the length of the vehicle W, and the parking range signal and Based on the position signal of the vehicle front and rear end detection means A,
Since the stop position determination means D determines whether or not the vehicle W is accommodated in the parking range, it is possible to know whether or not the vehicle W is reliably accommodated in the parking range according to the length of the vehicle W. . Therefore, the stop position of the vehicle W with respect to the parking range can be easily known, and the stop position of the vehicle W is easily corrected when the stop position of the vehicle W is out of the parking range, so that the vehicle W falls within the parking range having a length corresponding to the length. Securely accommodated. As a result, as shown in FIG. 1, a parking space c for small vehicles, which is shorter than a parking space b for large vehicles, can be partitioned, the number of vehicles W to be accommodated can be increased, and the accommodation of vehicles W can be accommodated. The efficiency can be improved.

Further, since the parking range is set in the central portion of the pallet 15, the vehicle W can be reliably arranged in the central portion of the pallet 15, so that the load balance of the pallet 15 during the transportation of the vehicle W is good. Can be held at. Further, as shown in FIG. 4, the variation in the positions of the wheels 19 of the large vehicle and the wheels 21 of the small vehicle becomes small, and the distance between the pair of wheel stoppers 17, 17 can be set small, so that the safety during transportation can be improved. Can be improved.

Next, as a modification of the above embodiment, a vehicle W
When the vehicle self-propels into the parking space a, the controller 31 displays an instruction regarding the accommodation destination of the parking space a on the display device based on the vehicle length signal from the vehicle length calculating means B, and the vehicle W You may guide to the parking space a according to the size.

The vehicle W for detecting the length of the vehicle
The front and rear edges of the storage device can be detected, for example, from the loading / unloading port 7 other than the loading / unloading chamber 9.
You may go in the waiting lane just before the entry. In this case, it is necessary to provide a vehicle detection sensor for detecting the front and rear ends of the vehicle on the standby road.

The vehicle detection sensor may be, for example, an ultrasonic sensor other than the phototube.

Further, the operation of detecting the front and rear ends of the vehicle by the front and rear end detecting means A of the vehicle may be other than the above embodiment. For example, when the vehicle W enters the pallet 15 of the loading / unloading chamber 9, one of the photoelectric detectors of the front detector 23 is used as a reference photoelectric detector, and the rear detector 25 at the moment when the reference photoelectric detector shields the front end of the vehicle W. The length of the vehicle W may be detected based on the light passing and light blocking states of the plurality of photoelectric tubes.

As the size of the parking space a, in this embodiment, the parking spaces b and c for large vehicles and small vehicles are used.
Although two sizes are provided, three or more sizes may be provided.

[0039]

As described above, according to the present invention, not only the vehicle length is detected, but the parking range detecting means calculates the parking range according to the length of the vehicle, and the stop position judging means performs the parking. Since it is determined whether the vehicle is accommodated within the range, it is possible to know whether the vehicle is reliably accommodated in the parking range according to the size of the vehicle, It can be reliably accommodated within the parking range. For this reason, the vehicle can be accommodated in a small parking space according to the length of the vehicle, and a large number of small vehicles having a small vehicle length can be parked, and the vehicle accommodation efficiency can be improved.

Further, if the parking range is set in the center of the pallet, the vehicle can be reliably placed in the center of the pallet, so that the load balance of the pallet during vehicle transportation can be maintained well. At the same time, the variation in the position of the wheels due to the size of the vehicle is reduced, and the distance between the wheel stops can be set small, so that the safety during transportation can be improved.
