Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a multistage parking facility. More specifically, the present invention relates to a multi-stage parking facility provided with a front fence that can be opened upward at the vehicle entrance and exit, and a safety detection device that detects the vehicle approaching the front fence and controls the operation of the fence. .
[0002]
[Prior art]
FIG. 5 shows an example of a conventional multistage parking facility 51. In this parking facility 51, vehicle-mounted pallets 52 are arranged in three stages, and each stage can accommodate three pallets. In this parking facility 51, the middle stage is used as a vehicle entry / exit floor, and two transverse pallets 52b are arranged. Three elevating pallets 52a and 52c are arranged in the upper and lower stages, respectively. Then, only one appropriate pallet 52a, 52c in the upper and lower tiers is moved up and down to the loading / unloading floor as the transverse pallet 52b in the middle tier crosses left and right.
[0003]
The vehicle entrance / exit 53 is provided with a front fence 54. Normally, the front fence 54 is located on the floor surface (closed position), and the entry / exit entrance 53 is closed. At this time, it is pulled upward (open position) to open the entrance / exit 53. The front fence 54 generally has a height of 800 to 1200 mm. When the front fence 54 is in the closed position, it is between the upper end of the front fence 54 and an obstacle such as the beam 55 or the upper pallet 52a above it. There is space. 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 cannot pass under the front fence or easily get over it. ing.
[0004]
A safety sensor 56 is disposed just outside the front fence 54 at the entrance / exit 53 to detect a vehicle or a person entering during the operation of the front fence 54. The operation of the safety sensor 56 stops the operation of the front fence that is being opened and closed to prevent interference between the front fence and a person or vehicle (hereinafter also referred to as a foreign object). Therefore, conventionally, the front fence 54 is stopped only when a vehicle or the like is detected during the closing operation from the top to the bottom, and is safe during the opening operation (when the front fence is moving upward in the direction away from the vehicle). Even if the sensor 56 detects a foreign object, it does not stop. This is because, in general, when a pallet on which his / her vehicle is to be loaded arrives at the loading / unloading floor, a user of the parking facility may not wait for the front fence to fully open and may try to enter during the opening operation. This is because if the safety sensor is activated at this time and the front fence stops during the opening operation, the driver of the vehicle enters without noticing it, and the vehicle and the front fence may interfere with each other. Therefore, even if the safety sensor 56 detects a foreign object during the opening operation, it is not stopped.
[0005]
As the safety sensor 56, an optical sensor using a photoelectric tube or the like is usually used to detect the person entering the parking facility or the front end of the entering vehicle, that is, the radiator grill or the bumper from the side. It is disposed at a position (a height position of about 500 mm from the floor surface).
[0006]
[Problems to be solved by the invention]
However, although the above-described conventional technique prevents a problem due to interference between the approaching vehicle and the front fence, a new problem may occur during the opening operation of the front fence. That is, since it is impossible to deny the possibility that a person hangs or loads a luggage on the front fence that is being lifted (opening operation), it is not desirable to raise the front fence until such a situation occurs. This is even more so in parking facilities where the manager who operates the parking facility does not reside.
[0007]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a multistage parking facility having a front fence that greatly reduces the occurrence of the above-described problem even during the opening operation of the front fence.
[0008]
[Means for Solving the Problems]
The multi-stage parking facility of the present invention is a front fence that can be opened upward disposed at the vehicle entrance and exit, a first detection device for detecting foreign matter disposed outside the front fence, And a control device that stops the operation of the front fence based on a signal from the first detection device, and when the first detection device detects a foreign object during the opening operation of the front fence in the control device. A first control range below the open stroke that stops the opening operation and a second control range above the open stroke that does not stop the opening operation even if the first detection device detects a foreign object are set.
[0009]
According to such a parking facility, during the closing operation of the front fence, the entrance of a foreign object is detected and the lowering of the front fence is stopped to prevent contact with the front fence in advance. Further, since a second control range in which it is safer to maintain the opening operation is provided, the contact between the vehicle and the front fence is greatly reduced.
[0010]
And it is the said parking equipment, Comprising: The 2nd control range is a range in which the lower end of the front fence in open operation is a predetermined height or more from a floor surface, and this predetermined height is a vehicle to the said parking equipment. A parking facility at a position where it is difficult to easily determine from the driver's seat that the front fence interferes with the vehicle due to the entry of the vehicle is preferable in the following points. That is, when the front fence rises to a position where the front fence and the vehicle cannot easily be judged by the driver during the opening operation of the front fence (the second control range), even if the approaching vehicle is Since the opening operation is maintained even if it is detected, the contact between the vehicle and the front fence is greatly reduced. Further, when the front fence reaches the second control range in the opening operation, that is, when the front fence is in a low position, this is detected, for example, when a child hangs on the front fence, and the opening operation is stopped.
[0011]
The upper part of the approaching vehicle is disposed at a position where a gap is formed between the front fence at the vehicle entry / exit opening and the upper end of the front fence when the opening front fence reaches the lower limit position of the second control range. And a second detection device for detecting foreign matter entering the gap, and the control device detects foreign matter in the second control range. In the parking facility that is configured to stop the opening operation of the front fence based on the signal from the second detection device sometimes, in addition to the above action, even in the second control range When a foreign object tries to enter above the rising front fence, this is detected and the opening operation of the front fence is stopped, preventing the foreign object from being caught between the front fence and the upper restriction. Is done.
[0012]
In addition, a plurality of the upper restriction portions are disposed apart from each other in the vertical direction, a third detection device for detecting a foreign substance entering between the upper restriction portions is disposed, and the control device is In the second control range, even if the parking facility is configured to stop the opening operation of the front fence based on a signal from the third detection device when the third detection device detects a foreign object. The situation that a foreign material is pinched | interposed between a front fence and an upper restriction part is prevented.
[0013]
And in the parking facility in which the lower limit position of said 2nd control range is made into the height range of 800-1900 mm from the floor surface, since it can apply easily also to the existing parking facility, it is preferable.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a multistage parking facility according to the present invention will be described with reference to the accompanying drawings.
[0015]
FIG. 1 is a perspective view showing an example of a parking facility according to the present invention.
[0016]
In the multistage parking facility (hereinafter simply referred to as parking facility) 1 shown in FIG. 1, the vehicle passes through the entrance / exit 2 and is placed on the pallet 3 for mounting on the vehicle located immediately before the entrance / exit 2. Get in. And in order to convey this vehicle to a predetermined position, the said pallet 3 is traversed, raised or lowered.
[0017]
In this parking facility 1, pallets 3 are arranged in three stages, two traversing pallets 3b are arranged in the middle stage which is the loading / unloading floor, and three lifting pallets 3a and 3c are arranged in the upper and lower stages, respectively. ing. Then, the middle row pallet 3b crosses to the left and right to make a space for one pallet at an arbitrary position, and only one of the upper pallet 3a and the lower pallet 3c is moved up and down there.
[0018]
The entrance / exit 2 is provided with a front fence 4. This front fence 4 is located on the floor surface in the closed state, and is pulled upward when the vehicle is loaded / unloaded, thereby opening the loading / unloading port 2. The front fence 4 is normally suspended by a chain, and is lifted by rotating the motor forward and then lowered by reversing the motor. The height dimension D of the front fence 4 is generally selected in the range of 800 to 1200 mm. The upper part of the entrance / exit 2 is restricted by the beam 5. In addition, the beam 5 and the upper pallet 3a limit the upper part of the vehicle entering and leaving the vehicle. The height H1 from the floor surface of the beam 5 and the upper pallet 3a is set in the range of about 1800 to 2500 mm according to the height of the vehicle that the parking facility 1 can accommodate. Generally, it is more than 1950mm for ordinary passenger cars and semi-high roof cars with a vehicle height of 1750mm or less, 2200H 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. From the above, a space is generated 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 restriction portion).
[0019]
As shown in FIGS. 1 and 2, first photosensors (photoelectric tube sensors) 6 as safety sensors are disposed outside the front fence 4 and on the left and right sides 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 2 and the light receiver 6b that receives the light R from the light emitter 6a is disposed on the left side (right side) of the entrance / exit 2. ing. These 6a and 6b are both outwardly spaced from the front fence 4 by about 5 to 10 cm, and are installed at a height of about 40 to 80 cm from the floor surface. Vehicles, humans, and the like are detected. A plurality of first photosensors 6 may be provided as necessary for this purpose.
[0020]
The parking facility 1 is provided with a control device 7 for controlling the opening / closing operation of the front fence 4. When the first optical sensor 6 detects a vehicle or a person approaching the front fence 4 while blocking the light beam R during the opening / closing operation of the front fence 4, the controller 7 detects the first optical sensor 6. The opening / closing operation of the front fence 4 is stopped based on the signal. The main purpose of stopping the opening operation by detecting a foreign object during the opening operation of the front fence 4 is to prevent the front fence 4 from being lifted as it is when, for example, a child hangs on the front fence. . In the parking facility 1, when the first optical sensor 6 detects a foreign object, the closing operation of the front fence 4 is stopped if the foreign object is in the closing operation, but the first control that is the lower range of the opening stroke is in the opening operation. It is made to stop only in the range. A second control range is set in the upper range of the open stroke of the front fence 4, and the first optical sensor 6 detects a foreign object while the front fence 4 passes through the second control range. However, the operation is not stopped. This second control range starts from the time when the lower end of the front fence 4 is opened from the closed state to the position of the predetermined height H2 (indicated by a two-dot chain line in FIG. 2), and the upper limit of the front fence 4 This is until the fully open position, which is the stop position. That is, in the open stroke, the upper part is the second control range and the lower part is 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 judgment error of the driver. There are also the following purposes. In other words, it is possible to prevent an accident that the user enters the vehicle without waiting while the front fence 4 is opened, and comes into contact with the front fence 4 in order to let the vehicle come out without noticing that the front fence 4 has stopped halfway. It is to be. For this latter purpose, the first optical sensor 6 may be installed in addition to the inner side separated by about 5 to 10 cm from the front rail 4 as necessary (not shown).
[0021]
The predetermined height H2 is a front surface that is considered to be difficult to determine that if a driver of a vehicle entering the parking facility enters from the driver's seat, the vehicle and the front fence interfere with each other. This is the height position of the bottom of the fence. In other words, if the vehicle enters, it is the upper limit height position at which it can be easily determined that the vehicle and the front fence interfere with each other. Specifically, for example, the height near the upper end of the windshield (windshield) of the vehicle or the height near the upper end of the rear glass can be considered. Although this height position H2 changes with kinds of vehicles, it is a height range of 800-1900 mm from a floor surface. In general, 800 to 1300 mm for ordinary passenger cars and semi-high roof cars (hereinafter referred to as low and high cars), and 800 to 1800 mm and 2100H high roof for high roof cars (hereinafter referred to as medium and high cars). For a car (hereinafter, referred to as a high car high car), it is selected from a 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, it is desirable that the height from the floor surface is 800 to 1300 mm.
[0022]
In each parking facility, even if the first optical sensor 6 detects a foreign object after reaching the second control range, the operation is not stopped. In other words, when the front fence 4 is at a position (first control range) lower than the second control range in the opening operation, and during the closing operation, the operation stops if the first optical sensor 6 detects a foreign object. Be made. Once stopped, the front fence 4 is re-activated by an operation such as an operator pressing an “open” button on an operation panel (not shown).
[0023]
In order to prevent the opening operation from stopping in the second control range, for example, a signal from the first optical sensor is used in the control device after a predetermined time has elapsed from the start of the opening operation using a timer (when the second control range is reached). May not be accepted, or the first optical sensor may not operate 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 activated to turn off the first light sensor, or the control device sends a signal from the first light sensor. Do not accept.
[0024]
With this configuration, after reaching the second control range during the opening operation of the front fence 4, the height of the upper edge of the front fence from the floor is higher than about 800 mm + 800 mm = 1600 mm, so that the child can hang down. On the other hand, since it is important to prevent interference between the approaching vehicle and the front fence in that range, the safety of the parking facility is improved if the opening operation is not stopped.
[0025]
Moreover, in order to eliminate the possibility of children 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 higher than or equal to the upper limit portion. Just be in 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 portion, so that a person cannot hang on the front fence 4. For this purpose, the total value of the height H2 of the lower limit position of the second control range and the height dimension D of the front fence 4 may be the same as or higher than the height H1 of the lower end of the upper restriction portion. In this way, the height dimension D of the front fence 4 and the height H2 of the lower limit position of the second control range may be selected.
[0026]
As an example of such a parking facility, in a parking facility for a low vehicle with H1 of 1950 mm, D shown in FIG. 2 is 1150 mm, H2 is 800 mm, and H1 is for a medium high vehicle with 2200 mm. In the parking facility, D is 1150 mm and H2 is 1050 mm. In the parking facility for high vehicles with H1 of 2300 mm, D shown in FIG. 2 is 1150 mm and H2 is 1150 mm. Conceivable.
[0027]
As long as the height dimension of the front fence 4 is in the range of about 800 to 1200 mm, the front fence 4 has reached the second control range in parking facilities for medium-high vehicles and parking facilities for high vehicles. There is a high possibility that a space is generated between the upper end of the front fence 4 and the lower end of the upper restriction portion. This is because the height of the upper restriction portion is high. As described above, in the parking facility in which a space is generated between the upper end of the front fence 4 and the lower end of the upper restriction portion when the front fence 4 reaches the second control range, a further detection device may be provided.
[0028]
FIG. 3 shows such a parking facility 11. The basic structure of the parking facility 11 is the same as that of the parking facility 1 in FIG. In the parking facility 1 of FIG. 1, when the height of the upper restriction part at the entrance / exit is relatively high and the front fence reaches the second control range, the upper end of the front fence and the lower end of the upper restriction part It shows a particularly preferable mode for a space in between. Here, the beam 15 is generally at a higher position 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 13 a and the beam 15. As an example of such a parking facility 11, in a parking facility for a low vehicle height where the height H1 of the beam 15 is 1950 mm, D is 1000 mm, H2 is 800 mm, and H1 is 2200 mm. In the parking facilities for medium and high vehicles, D is set to 1000 mm and H2 is set to 1050 mm. For the parking facilities for high vehicles and high vehicles having H1 of 2300 mm, D shown in FIG. The thing which made H2 1150mm can be considered. In addition, when the upper end of the front fence 14 is located under the upper stage pallet 13a, it mentions later, referring FIG.
[0029]
The parking facility 11 includes the first optical sensor 6 described above, and outside the space S between the front fence 14 and the beam 15 that is the upper restriction portion when the front fence 14 reaches the second control range. And the 2nd optical sensor 16 as a safety sensor is arrange | positioned at the left and right of the entrance / exit 12. The second light sensor 16 also has a light emitter disposed on the right side (left side) of the entrance / exit 2 and a light receiver disposed on the left side (right side) of the entrance / exit 2. The second light sensor 16 is located outside the front rail 14 by about 5 to 10 cm and is installed at a height of about 160 to 200 cm from the floor so as to correspond to the space S. All vehicles, humans, and the like that are blocked and approach the space S are detected. A plurality of second photosensors 16 may be provided as necessary for this purpose.
[0030]
The parking facility 11 is also provided with a control device (not shown) for controlling the opening / closing operation of the front fence 14. As in the parking facility 1 described above, when the first optical sensor 6 detects a foreign object during the opening / closing operation of the front fence 14, the control device is configured to control the first optical sensor 6 except for the second control range. Based on the detection signal, the opening / closing operation of the front fence 4 is stopped. Also in the second control range, when the second optical sensor 16 detects a foreign object, the opening operation of the front fence 4 is stopped based on the detection signal of the second optical sensor 16.
[0031]
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. This is because the beam 15 is generally higher than the upper pallet 13a as described above. 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 is divided into two vertically by the upper pallet 23a.
[0032]
As an example of such a parking facility, in a parking facility for a low vehicle height vehicle in which the height H1 of the beam 25 is 2000 mm and the height P of the upper pallet 23a is 1900 mm, D is 1000 mm. , H2 is 800 mm, H1 is 2250 mm, and the height P of the upper pallet 23a is 2150 mm. For parking equipment for medium-high vehicles, D is 1000 mm, H2 is 1050 mm, H1 is In a parking facility for a high vehicle with a height of 2400 mm and an upper pallet 23a having a height P of 2300 mm, it is conceivable that D shown in FIG. 2 is 1000 mm and H2 is 1150 mm.
[0033]
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. The optical sensors are arranged so as to correspond to the divided spaces S1 and S2. The second photosensors 16 are disposed outside the space S1 between the front fence 24 and the upper pallet 23a and on the left and right sides of the entrance / exit 22 and the space S2 between the beam 15 and the upper pallet 23a is arranged. Third optical sensors 17 are disposed on the left and right sides of the entrance / exit 12 at the outside. A plurality of second optical sensors 16 and third optical sensors 17 may be provided as necessary.
[0034]
In the parking facilities 1, 11, and 21 described above, an alarm device that issues an alarm when the optical sensors 6, 16, and 17 are activated and the opening and closing operations of the front rails 4, 14, and 24 are stopped may be provided.
[0035]
Moreover, in this invention, it is not limited to the H2 dimension (800 mm or more) demonstrated above. For example, you may set to 800 mm or less. This is because it is considered that children will hardly hang from the front fence once it has started to rise.
[0036]
【The invention's effect】
According to the present invention, during the opening operation of the front fence, when the front fence rises to the second control range, which is a range where the driver cannot easily determine that the front fence and the vehicle interfere with each other. Even if an approaching vehicle is detected, the opening operation is maintained, so that contact between the vehicle and the front fence is greatly reduced. Further, when the front fence reaches the second control range in the opening operation, that is, when the front fence is in a low position, this is detected, for example, when a child hangs on the front fence, and the opening operation is stopped. .
