Description

Passenger Conveyor Unit {PASSENGER CONVEYOR APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a passenger conveyor that detects a passenger and controls driving.

A passenger conveyor, such as an escalator or an electric walkway, which moves a person on the upper floor or the lower floor or horizontally, may detect the presence or absence of a passenger and automatically perform driving or stopping.

Conventional passenger detection apparatuses used in these automatic driving passenger conveyors emit light or ultrasonic waves and detect the presence or absence of passengers by detecting blocked or reflected waves by a person. For this reason, in the conventional passenger conveyor which performs automatic passenger detection, when installing passenger detection apparatuses, such as this, a photoelectric pole or an entrance guard is normally provided.

Fig. 5 is a side view of the escalator for automatic driving provided with a conventional passenger detection device. In the escalator shown in FIG. 5, it shows the case where it moves to the direction of the hatch 58 of the upper floor from the hatch 52 of the lower floor, and the passenger detection apparatus 55a, 55b, 57a, 57b normally installed is an escalator main body ( 51 is mounted on the upper portions of the photovoltaic poles 53a, 53b, 59a, and 59b which are erected at positions in front of the hatch 52 and the hatch 58. Further, when the passenger detecting device is installed at the position in front of the hatch, the time required for detecting the passage of the passenger and reaching a predetermined state of controlling the driving of the escalator until the passenger advances to reach the escalator's tread To be on time. Moreover, it is equipped in the upper part of the said photoelectric pole in order to suppress operation | movement, avoiding the sole lifting of children, pets, etc .. A photoelectric or ultrasonic passenger detection device that is usually used is used in one pair of the light emitting side (transmitting side) and the light receiving side (receiving side), and is thus provided on the left and right sides of each of the hatches 52 and 58. Enter between the hatch 52 and the photoelectric poles 53a and 53b and between the hatch 58 and the photoelectric poles 59a and 59b to reach the hatch 52 and 58 without passing through the photoelectric poles 53 and 59. Intrusion prevention measures 54a and 54b are provided so that it may become impossible.

In the conventional passenger conveyor described above, the passenger detection device requires the installation of two devices, which are a pair of the light emitting side and the light receiving side, and a problem in that the detection area is narrow in the light shielding method and sensitive to other light sources in the reflection method. There was. In addition, between these pairs of devices, there is a problem in that installation is restricted because an object which is an obstacle for signal detection, for example, a guide display board, cannot be provided. In addition, the photoelectric poles 53a, 53b, 59a, 59b or the intrusion prevention measure 54 provided near the hatch 52, 58 are undesirable in design because they feel a feeling of suppression and discomfort during passage.

If a detection device, especially a light receiver, is placed in an inconspicuous position, it is easy to mislead the detector to operate by detecting the light, and light from outside may accidentally enter the light receiver. There is an easy issue. In particular, when the passenger is already riding, as described above, if the passenger conveyor stops suddenly or the direction of movement changes due to the presence or absence of incident light of the light receiver, the passenger is offended or there is a safety problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the conventional passenger conveyor as described above, and an object thereof is to provide a passenger conveyor apparatus that does not give passengers a feeling of discomfort, restraint or discomfort, and has little meaningless operation or malfunction. .

EMBODIMENT OF THE INVENTION Hereinafter, the Example at the time of applying this invention to the escalator is demonstrated in detail using drawing.

1 is an overall configuration diagram showing an escalator according to an embodiment of the present invention, and describes a case in which a passenger moves in one direction from a lower floor to an upper floor. Fig. 2 shows a perspective view of the hatch of the lower floor serving as the boarding side in order to understand in more detail the configuration of the embodiment of the present invention.

The passenger conveyor main body 10 having one hatch 11a on the lower floor and the other hatch 11b on the upper floor is the two hatches 11a and 11b. The plurality of stepping plates 14 provided therebetween are connected and moved. The tread plate 14 is inserted into the left and right handrail base parts 12a and 12b and is moved, and the comb part 13a is provided in the part which the tread plate 14 of the lifting doors 11a and 11b pushes out, and the tread plate 14 is carried out. And the gap between the lifting holes 11a and 11b are reduced. In addition, handrails 15a and 15b are provided in the handrail base parts 12a and 12b, and the handrail belt moves on the upper part.

The first passenger detection devices 16a, 16b for detecting the passenger approaching the front lower part of the handrail base parts 12a, 12b on the lower door 11a side of the lower floor are mounted, and the comb teeth 13a are provided. Second passenger detection devices 17a, 17b for detecting a passenger are mounted on the lower side of the side of the installed guardrail bases 12a, 12b.

The first passenger detection devices 16a and 16b and the second passenger detection devices 18a and 18b are constituted by elements for detecting far infrared rays emitted from the human body, for example, having a wavelength of 7 to 14 µm. The detection devices 16a and 16b are installed to detect the approach of the passengers, and the second passenger detection devices 17a and 17b allow the passengers to ride on the treadmill 14 through the comb teeth 13a. Is installed to detect ".

In addition, although the passenger conveyor main body 10 demonstrates operation | movement to an upward direction here, the normal passenger conveyor main body 10 can drive up and down bidirectionally, and even when driving in the downward direction opposite to the above-mentioned, Similarly, the first passenger detection devices 18a and 18b and the second passenger detection devices 19a and 19b are mounted at the corresponding points of the railing bases 12a and 12b to detect the doors. It is.

The driving control device 110 installed in the machine room under the hatch 11b is an output signal of the first passenger detection devices 16a, 16b, 18a, and 18b and the second passenger detection devices 17a, 17b, 19a, and 19b. Receives to control the operation of the passenger conveyor body (10).

3 is a diagram showing a configuration example of a driving control apparatus 110 that performs driving control of a passenger conveyor according to the embodiment of the present invention. The driving control apparatus 110 for controlling the driving speed of the tread plate 14 of the passenger conveyor main body 10 includes a driving control main body apparatus 31, a power source 32 connected to the main body apparatus, and a driving motor 33. And a first switch 34 and a second switch 35 operated by two passenger detection devices, a boarding wait timer 37 and a driving time timer 39.

Next, the operation of the present embodiment will be described with reference to the timing of the passage of the passengers and the driving speed shown in Figs. 2, 3 and 4. When the passenger walks toward the hatch 11a serving as the doorway shown in Fig. 2, the first passenger detection devices 16a, 16b provided at the front lower portion of the rail handrails 12a, 12b approach from the front entry direction. Detect passengers. As the detection signal 36 of the 1st passenger detection apparatus 16a, 16b, the 1st switch 34 connected to the driving control main body apparatus 31 shown in FIG. 3 (a) is operated, and this apparatus 31 is operated. Recognizes as "arrival of the passenger", and sends a control signal to the stepping drive motor device 33 which accelerates the stepping plate 14 of the passenger conveyor from the air speed to the normal speed from the time indicated by t1 in FIG. At this time, the boarding wait timer 37 is also activated.

Next, the passenger further advances, and the second passenger detection devices 17a, 17b provided on the lower side of the rail bases 12a, 12b on both sides of the comb 13 of the hatch 11 are placed. When passing, the passenger's ride is detected (time t2). Therefore, by the detection signals 38 of the second passenger detection devices 17a and 17b, the switch 35 connected to the driving control body device 31 shown in FIG. 3 similarly operates to operate the driving control body device ( 31 recognizes the "ride of the rider" and forcibly resets the ride waiting timer 37. At this point in time, only the time taken until the passengers get off (set time 42), the driving time timer 39 is activated to send a control signal to the tread drive motor device 33 to continue the operation at the normal speed.

At a time point t3 when the setting time 41 of the driving time timer 39 has elapsed, it is estimated that the passenger has reached the upper floor, and the driving control device 31 sends a control signal for decelerating to the standby speed. 33). Then, from the time t4 at which the airspeed is reached, the deceleration is stopped to maintain the airspeed, and the state of waiting for operation of the next switch 34, that is, arrival of the next passenger, is reached.

In addition, when the second passenger arrives at the hatch 11a while the passenger is moving in the ride, the switch 34 is operated as the detection signal 36 of the first passenger detection devices 16a, 16b, and the driving control device. 31 recognizes the "arrival of the passenger", but since the passenger conveyor is operating at the normal speed, the boarding wait timer 37 is restarted while maintaining this speed. In addition, when the second passenger passes the second passenger detection devices 18a and 18b, the passenger's ride is detected, and as described above, the switch 35 is operated by the detection signal 38 to operate the driving control device 31. ) Recognizes the "ride of the rider", restarts the reset waiting timer 37 and the operation time timer 39, and sends a control signal to continue the operation at the normal speed. Then, when the setting time of the driving time timer 39 restarted by the pass detection signal 38 of the 2nd passenger detection apparatus 17a, 17b of the last passenger who boarded last time passes, the passenger reached the upper floor. Ends normal operation by estimation and decelerates.

In addition, when the passenger arrived at the hatch 11a at the time t5, the use of the passenger conveyor was stopped, and the passenger was not detected by the second passenger detection devices 17a and 17b within the "ride wait setting time 41". Then, the waiting wait timer 37 is reset to " set time elapsed " (time t6), and the driving control apparatus 31 sends a control signal to decelerate, and after reaching the waiting speed (time t7), Keep it. However, during the operation of the operation time timer 39, the operation time timer 39 is given priority and operation is maintained.

As described above, in the passenger conveyor according to this embodiment of the present invention, since the first passenger detection devices 16a and 16b are constituted by the detection elements by far infrared rays, it is possible to cover a wide range of the hatch 11 through which the passenger enters. Since it can cover and detect, and it is not necessary to install the receiving side and the transmitting side in combination, it is possible to install it without the need for additional equipment for installing a detection apparatus such as a photoelectric pole, and also needs additional equipment such as an entry prevention measure. I never do that. In addition, since the passenger detection device can be installed in an inconspicuous manner and position, it is difficult to attract mischief without a willingness to elevate, and meaningless driving can be avoided.

In addition, in the above embodiment, the second passenger detection device is provided in the horizontal railing bases 12a and 12b of the inconspicuous comb teeth. Therefore, a photoelectric or ultrasonic detection device composed of a light emitting side (transmitting side) and a light receiving side (receiving side) may be used as the second passenger detection.

Further, only the first passenger detection devices 16a and 16b are provided, and the second switch 35 is activated by the detection signal 36 from the first passenger detection devices 16a and 16b shown in Fig. 3B. A passenger having a driving control main body device 31a which is activated and starts a driving time timer 39a whose total T2a between the time required for "passenger's ride" and the "set driving time" is set as "the second set driving time." Conveyors can achieve the effect of not requiring additional equipment.

In the above embodiment, the first passenger detection device and the second passenger detection device have been detected in two steps. In this way, when the passengers are detected by the two-stage detection device, the passenger conveyor can be prepared in advance, and the passengers can be prevented from operating when the passengers do not actually ride the passenger conveyor, thus preventing efficient and meaningless operation. It can be effective. However, in the present invention, two or more detection apparatuses by far infrared rays are not necessarily required, and passengers can be detected by one.

Moreover, in the said Example, the far-infrared passenger detection apparatus was installed in two places left and right (namely, 16a, 16b, and 18a, 18b) in each hatchway. By configuring in this way, the sensing cover area of the detection element can be complemented, and the detection range can be expanded or limited by the sum or the product, thereby improving the passenger detection accuracy. However, as a matter of course, the passengers may be detected by one detection device, such as 16a and 18a.

The present invention is not limited to the escalator as described above. The present invention can also be used for an electric pedestrian without a step, and is generally applicable to a passenger conveyor. Moreover, this invention is a passenger conveyor which detects a passenger by far-infrared rays, and can be variously deformed and implemented within the scope of this technical idea, without being limited to the said Example.

As described above, according to the present invention, since the passengers are detected by far-infrared rays, there is an effect that a passenger conveyor with less malfunction can be obtained without requiring additional equipment.
