Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a multi-stage parking system. More specifically, the present invention relates to a multi-stage parking facility provided with a front fence capable of opening upward at a vehicle entrance and exit, and a safety detection device for detecting a vehicle approaching the front fence and controlling the operation of the fence. .

[0002]

2. Description of the Related Art FIG. 5 shows an example of a conventional multi-stage parking system 51. The parking equipment 51 includes a pallet 52 for mounting on a vehicle.
Are arranged in three stages, and each stage can accommodate three pallets. In this parking facility 51, the middle tier is used as the entrance / exit floor of the vehicle.
2b are arranged. Three lifting pallets 52a and 52c are arranged on the upper and lower stages, respectively. Then, as the middle pallet 52b traverses left and right, only one appropriate pallet 52a, 52c in the upper and lower tiers is raised and lowered to the loading / unloading floor.

[0003] A front fence 54 is provided at an entrance / exit port 53 of a vehicle. Usually, the front fence 54 is located on the floor surface (closed position) and the entrance / exit port 53 is closed. Entry / exit port 5 which is lifted upward (open position) during entry / exit
3 is opened. The front fence 54 is generally 80
It has a height of 0 to 1200 mm.
Is in the closed position, a space is formed between the upper end of the front fence 54 and an obstacle such as the beam 55 and the upper pallet 52a thereabove. Parking facilities are used by a large number of people who have received safety education, and the dimensions of the front fence are determined based on the basic idea that children can pass under the front fence or have a height that cannot be easily overcome. ing.

[0004] Immediately outside the front fence 54 at the entrance / exit 53, a safety sensor 56 is disposed to detect the entry of a vehicle or a person during the operation of the front fence 54. By the operation of the safety sensor 56, the operation of the front fence being opened / closed is stopped to prevent interference between a person or a vehicle (hereinafter, also referred to as a foreign substance) and the front fence. Therefore, conventionally, the vehicle is stopped only when a vehicle or the like is detected while the front fence 54 is closing from top to bottom, and is safe during the opening operation (when the front fence is moving upward in a direction away from the vehicle). Even if the foreign object sensor 56 detects a foreign substance, it does not stop. Because, in general, users of parking facilities
When the pallet on which the vehicle is to be mounted arrives at the loading / unloading floor, there is a case where the pallet cannot wait for the front fence to completely open and tries to enter during the opening operation. At this time, if the safety sensor is activated and the front fence stops in the middle of the opening operation, the driver of the vehicle enters the vehicle without noticing it, and the vehicle and the front fence may interfere with each other. Therefore, during the opening operation, the safety sensor 56 is not stopped even if it detects a foreign substance.

[0005] As the safety sensor 56, an optical sensor using a photoelectric tube or the like is usually used. The front end of a person entering the parking facility or a vehicle entering the vehicle, that is, a radiator grill or a bumper is laterally positioned. (At a height of about 500 mm from the floor).

[0006]

However, in the above prior art, although the problem due to the interference between the approaching vehicle and the front fence is prevented, a new problem may occur during the opening operation of the front fence. That is, since it is undeniable that a person may hang or carry luggage on the front fence during the ascent (during the opening operation), it is not desirable to raise the front fence until such a situation occurs. This is especially true in a parking facility where no manager who operates the parking facility is resident.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a multi-stage parking facility having a front fence that greatly reduces the occurrence of the above-mentioned problem even when the front fence is being opened. And

[0008]

SUMMARY OF THE INVENTION A multi-stage parking system according to the present invention detects a front fence provided at a vehicle entrance / exit and which can be opened upward, and a foreign object provided outside the front fence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a multi-stage parking facility according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an example of the parking equipment of the present invention.

In a multi-stage parking facility (hereinafter simply referred to as parking facility) 1 shown in FIG. 1, a vehicle passes through an entrance / exit port 2 and is located immediately in front of the entrance / exit port 2 for mounting on a vehicle. Ride on. Then, the pallet 3 is traversed, raised or lowered to transport the vehicle to a predetermined position.

In this parking facility 1, pallets 3 are arranged in three stages, two pallets 3b are arranged in a middle stage which is an entrance / exit floor, and three elevating pallets 3a, 3c are arranged in an upper stage and a lower stage, respectively. Is arranged. Then, the middle row pallet 3b traverses left and right, leaving a space for one pallet at an arbitrary position, and only an appropriate one of the upper pallet 3a and the lower pallet 3c is raised and lowered there.

The entrance 2 has a front fence 4. The front fence 4 is located on the floor surface in the closed state, and is lifted upward when the vehicle enters and exits to open the entrance 2. The front fence 4 is usually hung by a chain, is raised by rotating the motor forward and hoisting, and lowered by rotating the motor reversely. The height D of the front fence 4 is generally selected in the range of 800 to 1200 mm. The entrance 2 is limited at its upper part by a beam 5. In addition, the beams 5 and the upper pallet 3a limit the upper part of the vehicle entering and exiting the warehouse. The height H1 of the beam 5 and the upper pallet 3a from the floor surface is 1
It is set in the range of about 800 to 2500 mm according to the height of the vehicle that the parking facility 1 can accommodate. Generally, 2100mm or more for normal passenger cars and semi-high roof vehicles with a vehicle height of 1750mm or less, 2200mm or more for high roof vehicles with a vehicle height of 2000mm or less, and 2100H high roof vehicles with a vehicle height of 2100mm or less. On the other hand, it is selected from a range of 2300 mm or more. As described above, a space is created between the upper end of the front fence 4 in the closed state, the beam 5, and the upper pallet 3a (corresponding to the upper limit portion).

As shown in FIGS. 1 and 2, a first optical sensor (photoelectric tube sensor) 6 as a safety sensor is arranged outside the front fence 4 and on the left and right of the entrance / exit 2.
The light emitter 6a of the first optical sensor 6 is disposed on the right side (left side) of the entrance / exit port 2, and the light receiver 6b for receiving the light beam R from the light emitter 6a is disposed on the left side (right side) of the entrance / exit port 2. ing. These 6a and 6b are both 5 to 10
cm outside, 40-80c from the floor
It is installed at a height of about m and detects all vehicles, people, and the like approaching the front fence 4 while blocking the light rays R. If necessary for this purpose, a plurality of first optical sensors 6 may be provided.

The parking facility 1 is provided with a control device 7 for controlling the opening and closing operation of the front fence 4. The control device 7 controls the first optical sensor 6 during the opening / closing operation of the front fence 4.
Stops the opening and closing operation of the front fence 4 based on the detection signal of the first optical sensor 6 when the vehicle detects a vehicle, a person, etc. approaching the front fence 4 by blocking the light beam R. The main purpose of stopping the opening operation by detecting a foreign substance during the opening operation of the front fence 4 is to prevent the front fence 4 from being raised as it is, for example, when a child or the like hangs on the front fence. . In the parking facility 1, when the first optical sensor 6 detects a foreign object, if the foreign object is in the closing operation, the closing operation of the front fence 4 is stopped, but the first control in the lower range of the opening stroke is performed during the opening operation. It is designed to stop only in the range. A second control range is set in an upper range of the opening stroke of the front fence 4, and the first optical sensor 6 detects a foreign substance while the front fence 4 is passing through the second control range. It does not stop its operation. The second control range starts when the lower end of the front fence 4 is opened from a closed state on the floor to a position at a predetermined height H2 (indicated by a two-dot chain line in FIG. 2). This is until reaching the fully open position which is the stop position. That is, of the opening stroke, the upper part is defined as the second control range and the lower part is defined as the first control range at the height position of H2 from the floor.
This is to prevent the vehicle from interfering with the front fence 4 as much as possible even if the vehicle enters due to a driver's misjudgment. There are also the following objects. In other words, it is possible to prevent an accident in which the user enters the car without waiting while the front fence 4 is being opened and comes into contact with the front fence 4 in an attempt to leave the vehicle without noticing that the front fence 4 has stopped halfway. It is to be. For this latter purpose, if necessary, the first optical sensor 6 may be installed in addition to the inside located at a distance of about 5 to 10 cm from the front fence 4 (not shown).

The predetermined height H2 means that if a driver of a vehicle entering the parking facility enters from the driver's seat, it will not be easy to judge that the vehicle will interfere with the front fence. This is the height position of the lower end of the front fence. In other words, it is the upper limit height position where it can be easily determined that the vehicle and the front fence will interfere if the vehicle enters. Specifically, for example, it can be considered as the height near the upper end of the windshield (windshield) of the vehicle or the height near the upper end of the rear glass. This height position H
2 varies depending on the type of vehicle, but 800-1
The height range is 900 mm. Generally, it is 800 to 1300 mm for ordinary passenger cars and semi-high roof vehicles (hereinafter referred to as low vehicle height vehicles), and 800 to 1800 mm for high roof vehicles (hereinafter referred to as medium vehicle high vehicles).
For a 0H high roof vehicle (hereinafter referred to as a high vehicle height), the height is selected from the range of 800 to 1900 mm. As the upper limit height position H2 at which the driver can more reliably and easily determine the interference between the vehicle and the front fence, the height from the floor surface is set to 80.
It is desirable to set it to 0 to 1300 mm.

In each of the parking facilities, even if the first optical sensor 6 detects a foreign substance after reaching the second control range, the operation is not stopped. In other words, the front fence 4 is located at a position (first control range) lower than the second control range in the opening operation.
If there is, and during the closing operation, if the first optical sensor 6 detects a foreign substance, the operation is stopped. The temporarily stopped front fence 4 is reactivated by an operation such as pressing an “open” button on an operation panel (not shown) by an operator or the like.

In order to prevent the opening operation from stopping in the second control range, for example, after a predetermined time elapses from the start of the opening operation using a timer (at the time when the second control range is reached), the control device uses the first light The signal from the sensor may not be accepted, or the first optical sensor may be disabled after the predetermined time has elapsed. Alternatively, a limit switch is provided, and when the front fence 4 reaches the second control range, the limit switch is operated to turn off the power of the first optical sensor, or the control device outputs a signal of the first optical sensor. What should be done is not to accept.

With this configuration, after reaching the second control range during the opening operation of the front fence 4, the height of the upper end of the front fence from the floor is higher than approximately 800 mm + 800 mm = 1600 mm. The possibility of hanging is greatly reduced. On the other hand, it is important to prevent interference between the approaching vehicle and the front fence in that range, so that stopping the opening operation improves the safety of the parking facility.

Also, in order to reliably eliminate the possibility of the child hanging in the second control range, when the front fence 4 reaches the second control range, the upper end of the front fence is already at the same height as the above-mentioned upper limit part or the height thereof. It suffices if it is at a higher position. By doing so, no space is created between the upper end of the front fence 4 and the lower end of the upper restriction, so that a person cannot hang on the front fence 4. For that purpose, the sum of the height H2 of the lower limit position of the second control range and the height D of the front fence 4 may be equal to or greater than the height H1 of the lower end of the upper limit portion. Thus, the height D of the front fence 4 and the height H2 of the lower limit position of the second control range may be selected.

As an example of such a parking facility, H1 is 19
In the parking equipment for a 50 mm low and high vehicle, D shown in FIG. 2 is set to 1150 mm and H2 is set to 800 mm.
In the parking equipment for middle and high vehicles with H1 of 2200 mm, D is set to 1150 mm and H2 is set to 1050 mm. In the parking equipment for high vehicles with H1 of 2300 mm, D shown in FIG. H2 is 1150 mm
mm is conceivable.

The height of the front fence 4 is 800 to 1200 m.
As long as it is within the range of about m, in the parking facilities for medium and high vehicles and the parking facilities for high vehicles, when the front fence 4 reaches the second control range, the upper end of the front fence 4 and the upper limit are restricted. There is a high possibility that a space is formed between the lower end of the portion and the lower end. This is because the height of the upper limit portion is high. As described above, in a parking facility in which a space is formed between the upper end of the front fence 4 and the lower end of the upper limit portion when the front fence 4 reaches the second control range, it is preferable to provide a further detection device.

FIG. 3 shows such a parking facility 11. The basic structure of the parking facility 11 is the same as the parking facility 1 of FIG. In the parking facility 1 of FIG. 1, the height of the upper restriction portion at the entrance / exit is relatively high, and when the front fence reaches the second control range, the upper end of the front fence and the lower end of the upper restriction portion are closed. It shows a particularly preferred form of the space between them. Here, the beam 15 is generally located higher than the upper pallet 13a. In the parking facility 11, when the front fence 14 reaches the second control range, the upper end of the front fence 14 is located between the upper pallet 13a and the beam 15. An example of such a parking facility 11 is a beam 15
In a parking facility for a low-height vehicle having a height H1 of 1950 mm, D is set to 1000 mm and H2 is set to 800 m.
m, H1 is 2200 mm In the parking equipment for medium and high vehicles, D is 1000 mm and H2 is 1050
In the parking equipment for a tall vehicle with a height of 1300 mm, D shown in FIG.
2 may be 1150 mm. The case where the upper end of the front fence 14 is located below the upper pallet 13a will be described later with reference to FIG.

The parking facility 11 is provided with the first optical sensor 6 described above.
And safety sensors are provided outside the space S between the front fence 14 and the beam 15 serving as the upper limit when the front fence 14 reaches the second control range, and at the left and right of the entrance / exit port 12. A second optical sensor 16 is provided. In the second optical sensor 16 as well, its light-emitting device is arranged on the right side (left side) of the entrance / exit port 2, and its light receiver is arranged on the left side (right side) of the entrance / exit port 2. The second optical sensor 16 is an outer space separated from the front fence 14 by about 5 to 10 cm, and the space S
Is installed at a height of about 160 to 200 cm from the floor so that all vehicles, people, and the like approaching the space S by blocking the light rays R are detected. A plurality of second optical sensors 16 may be provided as needed for this purpose.

The parking facility 11 is also provided with a control device (not shown) for controlling the opening / closing operation of the front fence 14. When the first optical sensor 6 detects a foreign object during the opening / closing operation of the front fence 14 as in the parking facility 1 described above, the control device removes the first optical sensor 6 except for the second control range. The opening / closing operation of the front fence 4 is stopped based on the detection signal. Also, in the second control range, when the second optical sensor 16 detects a foreign substance, the opening operation of the front fence 4 is stopped based on the detection signal of the second optical sensor 16.

FIG. 4 shows the parking facility 21 in which the upper end of the front fence 24 is lower than the upper pallet 23a when the front fence 24 reaches the second control range. As described above, the beam 15 is generally located at a position higher than the upper pallet 13a. In this case, the space S between the front fence 24 and the beam 25 when the front fence 24 reaches the second control range.
Are vertically divided by the upper pallet 23a.

As an example of such a parking facility, a beam 25
The height H1 of the parking equipment for low and high vehicles is 2000 mm and the height P of the upper pallet 23a is 1900 mm, and D is 1000 mm and H2 is 800 mm.
In the parking facility for middle and high vehicles, H1 is 2250 mm and the height P of the upper pallet 23a is 2150 mm, D is 1000 mm, and H2 is 1050 mm.
In the parking equipment for a tall and high vehicle in which H1 is 2400 mm and the height P of the upper pallet 23a is 2300 mm, D shown in FIG. 2 is set to 1000 mm and H2 is set to 1
One having a size of 150 mm is conceivable.

In such a case, a third optical sensor 17 is provided in addition to the first optical sensor 6 and the second optical sensor 16. An optical sensor is provided so as to correspond to each of the two divided spaces S1 and S2. The second optical sensors 16 are disposed outside the space S1 between the front fence 24 and the upper pallet 23a and on the left and right of the entrance / exit 22 to define the space S2 between the beam 15 and the upper pallet 23a. The third optical sensor 17 is provided outside and on the left and right of the entrance / exit port 12. A plurality of the second optical sensors 16 and the third optical sensors 17 may be provided as necessary.

In the above parking facilities 1, 11, and 21,
When the optical sensors 6, 16, 17 are activated, the front fences 4, 14, 2
An alarm device that issues an alarm when the opening / closing operation of 4 stops may be provided.

The present invention is not limited to the H2 dimension (800 mm or more) described above. For example, 800
mm or less. This is because it is unlikely that children will hang on the front fence once it has begun to rise.

[0036]

According to the present invention, during the opening operation of the front fence, the front fence is a range in which the driver cannot easily judge that the front fence interferes with the vehicle. When the vehicle moves upward, the opening operation is maintained even if an approaching vehicle is detected, so that the contact between the vehicle and the front fence is greatly reduced. Further, in the opening operation, before the front fence reaches the second control range, that is, when the front fence is in a low position, for example, when a child hangs on the front fence, this is detected and the opening operation is stopped. .
