Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a safety device for a variable-speed moving walkway.
[0002]
[Prior art]
Recently, a variable-speed moving sidewalk that moves gently for passengers getting on and off and moves at high speed in the middle has been proposed. A typical example is a device as shown in FIG.
[0003]
That is, in FIG. 5, the endless circulating belts 1 to 6 having different speeds are installed in series, and the passengers riding on the belts are transported at a low speed near the entrance 7 and at a high speed in the middle portion on a variable speed moving sidewalk. is there.
[0004]
In such a moving sidewalk, the so-called crowding phenomenon occurs in which the distance between the passengers is reduced near the exit, and there is a possibility that the passengers may be overcrowded and a fall accident may occur. Therefore, a safety device 8 as shown in FIG. 6 has been proposed. I have. (For example, see Practical Document 1)
[0005]
[Practical Document 1]
Japanese Utility Model Registration No. 30111686
In this safety device 8, a single photoelectric device is provided in a molding 9 near the end of the fast main belt 6, and the number of times a passenger crosses a light beam within a predetermined time is counted. Is to detect the degree of congestion.
[0007]
[Problems to be solved by the invention]
However, detecting a crowded state of passengers with only one photoelectric device is not sufficient as a safety device, and a device that can more appropriately, reliably, and instantaneously grasp such a device has been desired.
[0008]
The present invention has been made in view of the above points, and has as its object to provide a safety device that can more accurately and instantaneously detect a crowded state of passengers.
[0009]
[Means for Solving the Problems]
The present invention
1. In with a passenger belt moving at speed V ₁ facing the doorway travelator, setting a detection device for detecting the distance between the passenger on the passenger belt at least 2 Kosonae, the arrangement interval of the detection device in order 350mm I do.
2. The belt that moves at the speed V _n, the moving walkway is installed a landing belt moving at speed V ₁ in series, the arrangement of a detection apparatus for detecting a distance between the passenger on the belt at least 2 Kosonae, detection device It is set to a value proportional to distance to the _V n / _{V 1.}
Things.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention provides a safety device that matches the speed of belts on a moving sidewalk composed of a plurality of belts.
[0011]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an overall view showing the arrangement of the detection device according to the present invention. In the figure, the same reference numerals as those in FIGS. 5 and 6 denote the same parts, where V ₁ is the speed of the belt 1 at the end of the exit (that is, the slowest speed), and V ₆ is the main belt 6 at the center. (That is, the fastest speed), 90 and 100 are detection devices according to the present invention, for example, a passenger detection device group including a plurality of photoelectric devices, and 90 is a device such as a skirt panel or an interior panel near a getting-on / off belt. A plurality of light emitters and light receivers are arranged in the balustrade 9 separately on the left and right, and the arrangement interval of each light emitter and each light receiver is said to be empirically aggregated, for example, to a limit dimension of about 350 mm. Is set.
[0012]
Next, 100 is a passenger detection device group composed of a plurality of photoelectric devices as in the case of 90. In one example, a plurality of light transmitters and light receivers are arranged in the balustrade 9 near the end of the main belt 6 in a right and left direction. , the arrangement interval _{L 1} of each projector and each photoreceiver _is set to about _{L 1 = 350mm * V n /} V 1. This interval is, if securing a spacing of more than L ₁ on the main belt 6, mean that the possible distance passengers than 350mm is on passenger belt 1, to prevent in advance the occurrence of the swarm to accurately Is what you can do.
[0013]
Here, the signal processing device 10 that processes signals between the plurality of detection devices performs, for example, the operation illustrated in FIG. For clarity, an example in which two photoelectric devices are arranged is shown. As can be seen from FIG. 2, when the first passenger blocks the light beam of the front photoelectric device and further does not block the light beam of the second photoelectric device, the second passenger blocks the front photoelectric device. It is determined that the convergence has occurred (detected by the detection device 90) or the convergence will occur (detected by the detection device 100), and the main belt 6 and the belts 2 to 5 in front of the getting on / off belt 1 are determined. Perform processing to reduce the speed. The same processing as described above is performed even if the second passenger blocks the light beam of the front photoelectric device while the first passenger blocks the light beam of the second photoelectric device.
[0014]
On the other hand, if the first passenger does not cut off the light beam of the photoelectric device while the first passenger cuts the light beam of the photoelectric device in front, and the next passenger does not cut off the light beam of the photoelectric device, no gathering has occurred or has occurred. No action is taken. When three or more such photoelectric devices are provided, the same operation as above may be performed between the second and third photoelectric devices.
[0015]
By the way, on a wide moving sidewalk, two people can ride side by side, so the way of thinking about gathering is slightly different. That is, there may be a case where the state shown in FIG. 3 is permitted in consideration of the area of each passenger. That is, it may be sufficient to detect only the interval between the passengers arranged on a line along the traveling direction.
[0016]
In this case, for example, a reflection type photoelectric device 100 '(detection distance limited type) or an infrared type reflection type sensor 100 "is provided in the balustrade 9 on both sides as shown in FIG. You should check for crowds.
[0017]
【The invention's effect】
As described above, according to the present invention, the distance between passengers along the traveling direction can be accurately and instantly detected, so that a very safe variable speed moving walkway can be obtained.
