Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and an electric road, and more particularly to a passenger conveyor suitable for detecting a passenger and automatically driving the passenger conveyor.

[0002]

2. Description of the Related Art Heretofore, there has been known an apparatus in which the presence or absence of a passenger using an escalator is detected and the operation of the escalator is automatically started and stopped. For example, Patent No. 25692
In the Japanese Patent Publication No. 42, a first detection device for detecting the passage of a passenger is disposed at an entrance at a position distant from the movable portion of the escalator, and the passage of the passenger at a position near the movable portion of the escalator at the entrance. And a third detection device for detecting the passage of a passenger at a position near the escalator movable portion at the exit of the escalator, and an escalator based on a detection signal of the first detection device. , The operation is continued for a predetermined time by the detection signal of the second detection device, and the operation of the escalator is stopped by the detection signal of the third detection device.

Further, Japanese Patent Publication No. 2569192 proposes a device in which a detecting device similar to the first and second detecting devices described above is provided, and an escalator is controlled by a combination of these detecting signals. .

[0004]

According to the escalator described in the former of the prior art (Patent No. 2569242), there is no wasted time when a single passenger uses the escalator, and power is saved. However, as described below, no consideration is given to the inconvenience that occurs when a plurality of passengers use the vehicle consecutively. The same is true of the latter (Patent No. 2569192) in that such inconvenience is not considered.

[0005] That is, when a plurality of passengers continuously use the vehicle, two or more passengers may pass through the detection device in an overlapping state. In such a case, the detection device detects the passage as one person, but when passing through another detection device, the overlap is eliminated and a problem occurs when there is an interval. For example, assume that three passengers get on the escalator consecutively and pass through the second detection device with the second and third passengers overlapping. In this case, the first and second detectors detect the first passenger and the escalator starts operating for a predetermined time, and then the third detector can confirm the passage of the first passenger. However, since the second detection device detects the second and third passengers as one,
After the second and third passengers have passed the second detector,
If there is an interval before reaching the exit, the third detection device will detect the passage of the second passenger, even though the third passenger is on the escalator.
There is a disadvantage that a stop command is output to the escalator. Further, at that time, when a new passenger passes through the first detection device, there is a disadvantage that the escalator is activated again.

[0006] The problem to be solved by the present invention is to solve the above-mentioned inconveniences, and to provide a safe operation even when a plurality of passengers enter the passenger conveyor continuously.

[0007]

In order to solve the above-mentioned problems, a passenger conveyor according to the present invention is provided such that a passenger conveyor is located at a position close to an end of a transfer section at entrances at both ends of the transfer section, and from this position to a side opposite to the transfer section. In the position, the detection devices for detecting the passage of passengers are respectively arranged, and these detection devices are first to fourth detection devices sequentially from the entrance side along the transport direction of the transport unit that transports the passengers, Each time a detection signal of the first detection device is input, an operation command of the transport unit is output for a first set time, and each time a detection signal of the second detection device is input, the first set time is canceled. And outputs the operation command of the transport unit for a second set time, and every time the detection signal of the third detection device is input, the second
A control device for canceling the set time and outputting the operation command of the transport unit for the third set time, and outputting a stop command of the transport unit every time the detection signal of the fourth detection device is inputted, The third set time is set based on the time required for the passenger to move from the position of each corresponding detection device to the position of the fourth detection device.

[0008] With this configuration, even if two people pass through the first detection device at an interval and then pass through the second detection device at an interval, the passenger who has passed through the second detection device afterwards , The operation time of the passenger conveyor is reset, so that the operation is continued until the later passenger gets off the passenger conveyor. In other words, even when a plurality of passengers get in consecutively, the driving time is finally determined when the last passing passenger is detected, so that the vehicle does not stop while riding. The same applies to the case where two persons pass through the second and third detecting devices in an overlapping manner and then pass through the third and fourth detecting devices at intervals.

Further, the third detection device is made effective after a fourth set time has elapsed since the detection signal of the second detection device is input, and the fourth set time is set to the second detection time. It is preferable to set the time equal to or slightly shorter than the time required for the passenger to move from the position of the device to the position of the third detection device. According to this, after two or more passengers pass over the second detection device, some passengers go up the escalator quickly, so that the distance between the passengers is greatly separated, and the previous passengers Even if the third detection device and the fourth detection device sequentially pass, the third detection device does not become effective, and the fourth detection device does not output an escalator stop command. You can reach the exit.

The fourth detection device is enabled after a lapse of a fifth set time since the detection signal of the third detection device is inputted, and the fifth set time is set to the third detection time. It is preferable to set the time equal to or slightly shorter than the time required for the passenger to move from the position of the device to the position of the fourth detection device. According to this, as in the case described above, even if some passengers pass through the third and fourth detecting devices at an early stage, the stop command of the escalator is not output from the fourth detecting device, and the third and earlier detection devices are not output. Will be stopped in accordance with the driving time of the detection device, and subsequent passengers can safely reach the exit.

The first to fourth detection devices for detecting the passage of a passenger irradiate a light beam on a passage of the passenger and block the light beam to thereby detect the passage of the passenger. A known passenger passing detection device, such as a detection device of the above, or a detection device to which an energy beam is applied instead of the light beam can be applied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a passenger conveyor to which the present invention is applied will be described below with reference to FIGS.
FIG. 1 is a side view showing a schematic configuration of an escalator according to an embodiment to which the present invention is applied. FIG. 2 is a flowchart showing a control operation of the escalator control device of the embodiment shown in FIG.

As shown in FIG. 1, the escalator 3 has an entrance 2 located on the lower floor and an entrance 3 located on the upper floor. A plurality of steps 4 corresponding to a transport unit are connected and movably arranged, and handrails 5 which move in synchronization with the steps 4 are formed on both sides on which the steps 4 move by being guided and supported by a balustrade 6. ing.

A pillar 7 is provided in the passenger passage on the side opposite to the stepping side of the entrance 2 on the lower floor, and a first detecting device 8 for detecting the passage of a passenger is provided on the pillar 7. The position of the first detection device 8 is separated from the reversing part of the handrail 5 by a distance L (for example, 1.5 to 2.0 m). Also, a second detecting means for detecting the passage of a passenger near the balustrade 6 at a position closer to the first detecting device 8 than the end of the step 4 by a distance S1 on the step 4 side of the first detecting device 8. Is provided. On the other hand, the third detection device 10 is similarly provided near the balustrade 6 at a position separated by a distance S2 from the end of the step 4 toward the opposite side of the step from the end of the step 4 at the entrance 3 of the upper floor.
Then, at a position further away from the position of the third detection device,
That is, the distance L (e.g.,
1.5 to 2.0 m), the support 12 is provided at a distance,
The support 12 is provided with a fourth detection device 11.
An operation control device 13 that controls the operation and stop of the escalator based on the detection signals of these detection devices 8, 9, 10, 11 is installed in a machine room formed below the entrance 3.

Next, the operation of the escalator of FIG. 1 will be described with reference to the flowchart of FIG. Here, an example in which the elevator of FIG. 1 is driven to move in one direction from the lower floor side to the upper floor side will be described.
First, when a passenger walks toward the entrance 2 on the entrance side and passes through the position of the first detection device 8, a first detection signal indicating that the passenger has passed from the first detection device is driven. Output to the control device 13.

The operation control device 13 starts the control in response to the input of the first detection signal (S11), outputs an operation command to the escalator, and at the same time, outputs a first set time T.
1 is started (S12). Thereby, the escalator is activated. The first set time T1 is when the passenger
Is set to the time required from passing through the detecting device 8 to passing through the fourth detecting device 11 with some margin added. That is, from the first detection device 8 to the second detection device 9
, The time B from the second detection device 9 to the third detection device 10, and the third detection device 10
T1 = (A + B + C + α) by adding the time C from the time to the fourth detection device 11 and the margin time α. When a plurality of passengers use the vehicle continuously, the setting time T1 is sequentially set again. As a result, the time from when the last passing passenger is detected becomes the final setting time T1.

Next, it is determined whether or not the passenger has passed the second detection device 9 based on the presence or absence of the input of the second detection signal (S13). If the determination is affirmative (YES), the process proceeds to step S14, where the operation command is continuously output to the escalator, and at the same time, the first set time T1 is canceled.
Timing of the second operation time T2 is started. Here, T2
Is set to the time required for a passenger to pass from the second detection device 9 to pass through the fourth detection device 11 with some allowance added. That is, T2 = (B + C + α) is set. Thereby, the operation of the escalator is continued. The set time T2 also becomes the final set time T2 from the time when the last passing passenger is detected, similarly to the above-described T1.

As described above, when the escalator is driven for a sufficient set time T1 required for the passenger to reach the exit when passing through the first detection device 8, the first detection device is operated. Even after passing through 8, even if the user gets absorbed in the story and gets into the steps 4 slightly, it is possible to avoid the inconvenience of stopping halfway. In particular, when passing through the second detection device 9, the set time T1 is canceled and a new set time T2 is set.
, It is possible to prevent a problem that the vehicle stops on the way while moving on the steps 4.

On the other hand, if the determination in step S13 is negative (NO), the process proceeds to step S31, where it is determined whether or not the time T1 has elapsed. If the determination is affirmative (YES), a stop command is output to output the escalator. It stops (S32), and returns to step S12 if negative (NO). This allows
It is possible to cope with a case where the passenger returns after passing through the first detection device 8 without getting on the escalator.

After the processing at the time of passing through the second detecting device 9, in step S15, it is determined whether or not the measured time of the operating time T2 has reached the fourth set time T4. 3 is enabled (S1).
6). Here, T4 is set equal to or slightly shorter than B. That is, in the normal case, the third detection device 1
The detection signal of the third detection device 10 is validated at a time when it is considered to pass zero. Next, in step S17, it is determined whether or not the signal has passed through the third detection device 10 based on whether or not the third detection signal has been input. If the determination is affirmative (YES), the process proceeds to step S18, where the escalator is operated. At the same time, the second set time T2 is cancelled, and the measurement of the third drive time T3 is started. Here, T3 is set to the time required for a passenger to pass from the third detection device 10 to pass through the fourth detection device 11 with some allowance added. That is, T3 = (C +
α). This set time T3 is also equal to T1 or T
Similarly to 2, the last set time T3 is from the time point when the last passing passenger is detected.

The period during which the third detection device is enabled is set to a period until the escalator stops. With this setting, the third passenger 10 can detect the last passenger, and after passing through the second detector 9, the passenger steps on or returns on the steps 4. , Even if the passage through the third detector 10 is delayed,
Can be detected.

Next, at step S19, the operation time T
It is determined whether or not the measured time of No. 3 has reached the fifth set time T5, and when it has reached, the fourth detecting device 11 is enabled (S
20). Here, T5 is set to a value equal to or slightly shorter than C. That is, in the normal case, the fourth detection device 1
The detection operation of the fourth detection device 11 is enabled at a time when it is considered to pass through No. 1. Next, in step S21,
It is determined whether or not the signal has passed the fourth detection device 11 based on whether or not the fourth detection signal has been input. If the determination is affirmative (YES), the process proceeds to step S22, in which a stop command is output, and the escalator is output. To stop.

On the other hand, step S17 and step S21
If the determination in (NO) is negative (NO), the process proceeds to steps S33 and S34, respectively, and when the set time T2 or T3 has elapsed, the process proceeds to step S22 to stop the escalator.

As described above, according to the present embodiment,
The following effects are obtained. (1) Even if a passenger stops before the second detection device 9 and gets into the step 4 late, if the vehicle passes through the second detection device 9, the driving set time is updated. Therefore, the operation of the escalator continues to reach the exit. As a result, it is possible to prevent inconvenience such as stopping during the movement on the steps 4.

(2) Even after stepping on the step 4 and stepping or returning backward, the passage of the third detecting device 10 is delayed,
If the vehicle passes through the third detection device 10, the set time of operation is updated, so that the operation of the escalator continues until the vehicle gets down reliably, and it is possible to prevent inconveniences such as stopping while moving on the steps 4. Can be.

(3) The escalator is stopped after the third detecting device 10 is operated and the fourth detecting device 11 is further operated, so that when the passenger arrives at the exit surely, In addition, since the escalator can be stopped without fail, it is possible to achieve a safe and highly efficient power saving effect by reducing unnecessary idle time.

As the detection device in the above embodiment, a photoelectric beam type or an energy ray application type is most suitable.
Well-known detection devices instead of these can be applied as they are.

Although not described in the above embodiment, when the escalator is in the stop state, the passenger passes through the fourth detecting device 11 in an attempt to get in from the exit side in the opposite direction to the predetermined moving direction. Then, the escalator is driven in a predetermined moving direction for a predetermined time (for example, 10 to 30 seconds),
It is possible to add a function to notify passengers that they cannot get on.

Also, in the above-described embodiment, the case of moving from the lower floor to the upper floor has been described as an example. However, it is easily understood by those skilled in the art that the same can be applied to the case where the moving direction is opposite. It is clear that it can be understood. That is, when moving from the upper floor to the lower floor, the fourth detector 1
1 is a first detection device, a third detection device 10 is a second detection device, a second detection device 9 is a third detection device, and a first detection device 8 is a fourth detection device. By substituting, it can be applied as it is.

[0030]

As described above, according to the present invention,
Even when a plurality of passengers get on the passenger conveyor continuously, they can be operated safely and have an effect of power saving.
