Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatically operated escalator device, and more specifically, to start the escalator based on the detection result of a user detector provided in the vicinity of the entrance of the escalator, and the elapse of a set time by a stop timer. The present invention relates to an escalator device that is automatically stopped later.

[0002]

2. Description of the Related Art In this type of escalator device,
In general, safety measures (for example, clear display of driving contents, securing of an appropriate taxiway, etc.) specified in JEAS-410A are adopted. However, in the conventional escalator device, the user detector provided in the vicinity of the entrance detects the user approaching the entrance and activates the escalator, but by simply detecting the passage of the human body. However, since the presence of the human body on the escalator cannot be detected, the following problems may occur.

For example, an elderly person who is unfamiliar with automatic driving
After activating the escalator across the detection field of view of the user detector, hang it up at the entrance and get on the escalator, or after a child gets on the escalator, go up and down the steps in the opposite direction and play. Because I did
There is a possibility that the escalator will stop halfway because the time set by the stop timer has elapsed.

Further, in this state, when the next user approaches the boarding gate and enters the visual field of detection of the user detector, the stopped escalator on which an elderly person or a child is riding suddenly activates. In addition, if there is a person who accidentally gets into the stopped escalator from the opposite direction or intentionally gets into the stopped escalator from the exit side with the feeling of climbing up or down the normal stairs, user detection The escalator remains stopped because it is not detected by the detector, but when the next user approaches the boarding gate and enters the detection field of view of the user detector while ascending and descending, the escalator remains stopped. The escalator will suddenly start. Stop these
Since the activation is unrelated to the user's intention, it may lead to an accident such as a fall or a fall depending on the riding posture of the user.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the prior art. The object of the present invention is to provide an automatically operated escalator device in which a user is on or off the escalator. In order to ensure safety by keeping driving in the state of being in the mouth, make sure that those who are trying to get into the stopped escalator from the exit side are clearly aware that the approach direction is incorrect. To do.

[0006]

The technical means adopted by the present invention to achieve the above object are as follows. That is, a feature of the present invention is that the escalator device is configured to start the escalator based on the detection result of the user detector provided near the entrance of the escalator and automatically stop the escalator after the elapse of the set time by the stop timer. A boarding detector composed of a light source that emits a beam across the entrance and exit and a receiver for the beam is provided so that the stop timer does not count during detection of the user on the escalator by the boarding detector. On the other hand, in the vicinity of the exit of the escalator, a reverse approach detector that detects a reverse approacher to the exit is installed, and an audible alarm is generated based on the detection result of the reverse approach detector and the escalator is activated. The configuration is such that the escalator is automatically stopped after the elapse of the time set by the stop timer.

[0007]

According to the above construction, the escalator is activated by the user detector provided near the entrance detecting the user approaching the entrance, and the escalator is automatically stopped after the time set by the stop timer has elapsed. Since a boarding detector consisting of a light source that emits a beam in parallel with the escalator extending from the entrance and exit to the exit and a light receiver is provided, when the user is on the escalator Even if it is exposed, the human body will block the beam, and the passenger detector will detect the user on the escalator.

During this detection, the stop timer does not count and the operation of the escalator continues, so after starting the escalator, hang it up at the entrance and then board the escalator or board the escalator. After that, even if you step up and down the steps in the opposite direction and hang up on the escalator, the escalator does not stop halfway through the time set by the stop timer and therefore the user The stopped escalator that is on board does not start unexpectedly.

[0009] Further, if the user tries to get into the stopped escalator from the opposite direction by mistake, or if he / she tries to get into the stopped escalator from the exit side with the feeling that he / she is going up and down the normal stairs, the reverse escalator near the exit is provided. The intruder detector detects it and generates an alarm sound for a predetermined time, and at the same time, activates the escalator.Therefore, it is necessary to make a reverse intruder recognize that the approach direction is wrong from the alarm sound and the rotation direction of the escalator. Become. In this state, if the boarding detector does not detect a human body, the escalator will automatically stop after the elapse of the time set by the stop timer.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, A is an ascending escalator device and B is an ascending escalator device, which are installed close to and parallel to each other at predetermined positions in a building such as a bank. 1A and 1B are escalators, 2A and 2B are entrances, and 3A and 3B are exits.
A boarding / alighting board 4 is provided. The taxiways for the entrances 2A and 2B and the exits 3A and 3B are fences 5 ... and partition walls 6 ...
Are separated from each other by, for example. Arrows a and b indicating the direction in which the user should enter are marked on the floor of the entrance to the taxiway, and a mark indicating that the exit is on the floor of the exit (for example, a cross or reverse Directional arrows) c and d are marked.

In the vicinity of the entrances 2A and 2B, user detectors 7A and 7B composed of a pair of photoelectric posts (a post equipped with a light source and a post equipped with a light receiver) are provided. Detection is performed by blocking beams (infrared rays, etc.) 8a and 8b emitted from the photoelectric post toward the other photoelectric post by the human body of the user. Then, the escalator 1A, 1B is activated based on the detection result of the user detector 7A, 7B, and is automatically stopped after a lapse of a time (for example, 60 seconds) set by the stop timer. Also, based on the detection results of the user detectors 7A, 7B, the escalator 1A, 1
At the same time as B starts up, a predetermined message from the speaker 9 built in the balustrade's manual ... "Thank you for visiting us. Thank you for visiting our store. Please ride inside. If you are with children, please hold your hands and ride in the center of the step .... "will be announced automatically.

In the escalator devices A and B which are automatically operated by such control means, in this embodiment,
Entrances 2A, 2B and exit 3 of escalator 1A, 1B
A boarding detectors 11A and 11B are provided which are composed of a light source that emits beams (visible light may be used, but infrared rays are used in this embodiment) 10a and 10b and light receivers for the beams 10a and 10b. Escalator 1
No matter where the user is on A or 1B, the detection is performed by partially blocking the beams 10a and 10b of the human body, and the boarding detectors 11A and 1B are also provided.
The stop timer does not count while the user on the escalator 1A, 1B is being detected by 1B.
Also, while the stop timer is counting, the user detector 7
The stop timer is reset when any of A, 7B and the boarding detectors 11A, 11B detects a human body. Further, the boarding detectors 11A and 11B are configured not to function while the escalators 1A and 1B are stopped. That is, erroneous activation is prevented when the boarding detectors 11A, 11B detect an obstacle for some reason while the escalator 1A, 1B is stopped. It should be noted that one of the light source and the light receiver is provided on the side of the entrances 2A and 2B, and the other is provided on the side of the exits 3A and 3B.

Further, in the above embodiment, the escalator 1
Reverse entrance detectors 12A and 12B for the exits 3A and 3B, which are composed of a pair of photoelectric posts, are provided near the exits 3A and 3B of A and 1B, respectively, and one photoelectric post to the other Detection is performed by blocking the beams (infrared rays, etc.) 13a and 13b emitted toward the photoelectric posts from the human body of the user. Then, based on the detection results of the reverse intruder detectors 12A and 12B, an alarm sound is generated for a predetermined time (for example, 10 seconds) by the speaker 9 ... Or a buzzer (not shown), and at the same time, the escalators 1A and 1B are activated. The warning sound and the rotation direction of the escalator 1A, 1B are made to cause the reverse approacher to recognize that the approach direction is wrong. In this state, if the boarding detectors 11A and 11B do not detect a human body, the escalators 1A and 1B are automatically stopped after a lapse of a time (for example, 60 seconds) set by the stop timer.

According to the above structure, the user detectors 7A and 7B provided near the entrances 2A and 2B are provided in the entrances 2A and 2B.
Escalator 1 by detecting the user approaching
A and 1B start up and automatically stop after the time set by the stop timer elapses, but the entrances 2A and 2B and the exits 3A and 3
Since the boarding detectors 11A and 11B each including a light source that emits beams 10a and 10b parallel to the escalator 1A and 1B and a light receiver are provided, when the user is on the escalator 1A and 1B, , No matter where the user is being carried, the human body is in the beam 10a, 10b.
As a result, the passengers on the escalators 1A and 1B are detected by the boarding detectors 11A and 11B.

During this detection, the stop timer does not count and the escalator 1A, 1B continues to operate,
After activating the escalator 1A, 1B, the entrance 2A,
You can hang up at 2B and then get on the escalator 1A, 1B, or get on the escalator 1A, 1B and then go up and down the steps in the opposite direction to get to the escalator 1A, 1B.
Even if you hang out on 1B, the escalator 1A, 1B will be stopped halfway after the time set by the stop timer has passed.
Does not stop, and therefore the stopped escalator 1A, 1B on which the user is riding does not start unexpectedly.

In this embodiment, the escalator 1A,
Since the horizontal width of 1B is narrow, one beam 10a, 10b is configured to pass through the central portion in the width direction, but when the horizontal width of the escalator 1A, 1B is wide, a plurality of light sources and light receivers are provided. By arranging them side by side, by running two or more beams in parallel in the width direction, it is possible to detect any position in the lateral width direction of the steps of the escalator 1A, 1B by the user. Alternatively, by devising the configuration of the light source and the light receiver, one beam 10a, 1
It is necessary to widen the width of 0b.

Further, the escalator 1 being stopped may be erroneously attempted to get into the stopped escalator 1A or 1B from the opposite direction, or as if climbing up or down a normal staircase.
When trying to get into A and 1B from the exits 3A and 3B side, the reverse approach detectors 12A and 1 near the exits 3A and 3B are detected.
2B detects it and generates an alarm sound for a predetermined time, and at the same time activates the escalator 1A, 1B, so that the reverse approacher recognizes that the approach direction is wrong from the alarm sound and the rotation direction of the escalator 1A, 1B. I will let you.
In this state, if the boarding detectors 11A and 11B do not detect a human body, the escalators 1A and 1B will automatically stop after the time set by the stop timer has elapsed.

Therefore, as in the case where a non-return mechanism for mechanically preventing a reverse approach is provided at the exit of the taxiway on the side of the exits 3A, 3 side, the normal walking of the user is hindered and the user is not allowed to walk. You can secure safety without giving a pleasant feeling.

The operation of the escalator devices A and B in the automatic operation mode will be described below with reference to the flow charts of FIGS. 4 and 5. First, the normal operation in which the user enters through the entrances 2A and 2B will be described with reference to the flowchart of FIG.

When the user detectors 7A, 7B detect a user (S1), the escalator 1A, 1B is activated, and at the same time, the auto-announce device operates to cause the speaker 9 to operate.
A predetermined message is announced from ... (S2).

At (S3), the boarding detectors 11A, 1A
When 1B detects a human body, the operation of the escalator 1A, 1B is continued (S4), but if not detected, the stop timer starts counting (60 seconds) (S5).

In (S6), while the stop timer is counting, the user detectors 7A, 7B and the boarding detector 11A,
When any of 11B detects a human body, the stop timer is reset (S7) and returns to (S3), but when the human body is not detected, the set time by the stop timer (60 seconds)
Is determined (S8), and if not, the operation of the escalator 1A, 1B is continued (S8).
9), the process returns to (S6), but if the time has passed, the escalator 1A, 1B is stopped and the announcement by the speakers 9 is stopped (S10).

Next, the operation at the special time when the user reversely enters from the exits 3A and 3B will be described with reference to the flowchart of FIG. By the reverse approacher detectors 12A and 12B detecting the reverse approacher (S1), the escalators 1A and 1B are detected.
The alarm sound is emitted for a predetermined time (10 seconds) at the same time as is activated (S2), and the stop timer is counted (60 seconds).
Is started (S3).

In (S4), when the user detectors 7A and 7B detect a human body while the stop timer is counting, the normal operation flow described above is entered, but the user detectors 7A and 7B detect the human body. If not, it is judged whether or not the time set by the stop timer (60 seconds) has elapsed (S5). If not, the process returns to (S4), but if it has elapsed, the escalator 1A, 1B Stops (S
6).

[0025]

Since the present invention has the above-described structure,
The following effects can be obtained. During detection of the user on the escalator by the boarding detector, the stop timer does not count and the operation of the escalator continues, so after starting the escalator, hang up at the entrance and then board the escalator, or After getting on the escalator, even if you step up and down in the opposite direction and hang up on the escalator,
The escalator does not stop midway after the time set by the stop timer has elapsed, and therefore the stopped escalator on which the user is riding does not start unexpectedly. If you accidentally try to get into the stopped escalator from the opposite direction, or if you try to get into the stopped escalator from the exit side with the feeling that you are climbing up or down the normal stairs, the reverse approach detector near the exit will be detected. When this is detected and an audible alarm is generated for a predetermined time, the escalator is activated at the same time, so that the reverse pedestrian recognizes that the approach direction is wrong from the alarm sound and the rotating direction of the escalator. Therefore, as in the conventional case, while the escalator that is stopped is climbing up and down, the next user approaches the boarding gate and enters the detection field of view of the user detector, and the escalator that is stopped suddenly starts. There is no inconvenience, and as a safety measure, as a non-return mechanism that mechanically prevents reverse approach is installed at the exit of the taxiway on the exit side, it prevents normal users from walking or It doesn't make you feel uncomfortable. By providing a large number of photoelectric detectors on the side surface of the balustrade of the escalator, it is possible to make the same function as the boarding detector, but in this case, the number of detectors becomes enormous and very large. Be expensive. In this respect, according to the present invention, since the beam is run across the entrance and exit, that is, the beam is run parallel to the escalator in a plan view, the number of detectors is small, and safety is ensured economically. Can be achieved.
