Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a control device for a plurality of passenger conveyors arranged in series.

[Conventional technology]

An example of an operation control device for a plurality of passenger conveyors arranged in series is disclosed in, for example, Japanese Patent Laid-Open No. 49-94083.

The passenger conveyor control device shown here detects when one of multiple passenger conveyors arranged in series has stopped and stops the passenger conveyor that is linked to the stopped passenger conveyor. It is controlled in conjunction with the

In recent years, many people's conveyors installed in public facilities and the like have been adopted as people's conveyors that can be operated at lower speeds than normal speeds for elderly people, disabled people, and the like.
In addition, in order to increase transportation capacity, many passenger conveyors that can operate at higher speeds than normal speeds have been installed.

These passenger conveyors are capable of switching speeds. There is no known control device capable of interlocking control of a passenger conveyor capable of switching these speeds.

[Problem that the invention attempts to solve]

Assume now that three escalators are arranged in series and all of them are operating at high speed. In this case, passengers are transported from the first floor to the fourth floor by successively transferring to three escalators.

The first to transport passengers to the top floor in such cases
When only one escalator was switched to low-speed operation, passengers transported by the second and third escalators connected to it filled the third floor, increasing congestion, creating an extremely dangerous situation and causing an accident. There is a risk that Particularly in stations, etc., where there are a large number of passengers, the time it takes for the third floor to be flooded with passengers due to congestion is extremely short, which is not desirable from a safety standpoint.

This idea is intended to solve the above-mentioned drawbacks, and when multiple speed-switchable passenger conveyors are arranged in series and operated in a predetermined direction,
To provide a passenger conveyor control device capable of alleviating passenger congestion by interlockingly controlling other passenger conveyors even when the operating speed of one of the passenger conveyors is switched.

[Means for solving problems]

The control device for a passenger conveyor according to this invention is such that when a plurality of passenger conveyors whose speeds can be switched in at least two stages are arranged in series and operated in a predetermined direction, one of the plurality of passenger conveyors is set to the first speed. This device is provided with a means for switching the operating speed of the passenger conveyor transporting passengers toward the passenger conveyor from the second operating speed to the first operating speed when the operating speed is switched to the first operating speed.

[Effect]

When any one of the passenger conveyors is switched from the second operating speed to the first operating speed, a switch operation occurs in the control circuit of the switched passenger conveyor.

This switch operation is detected by the control circuit of the passenger conveyor that is transporting passengers toward the switched passenger conveyor. Based on the detection result, a switching operation is performed to change the passenger conveyor, which is being operated at the second operating speed, to the first operating speed.

In this way, successive passenger conveyors are switched from the second operating speed to the first operating speed.

Next, first, the control operation of the first escalator will be explained. Now, a case will be described in which a high-speed ascending operation is performed with the first to third escalators 5 to 7 stopped. When the speed changeover switch 13 of the first escalator 5 is turned to the high speed side, the power (+) - stop switch 12 - speed changeover switch 13 is turned on.
- The high-speed operation relay 14 is energized by the circuit of - contact 16b - contact 15a - relay 14 - power supply (-). Next, when the upward operation switch 8 is pressed, the upward operation relay 10 is energized by the circuit of power supply (+) - stop switch 12 - upward operation switch 8 - contact 11c - relay 10 - power supply (-), and contact 1
0a and 10b are closed, and contact 10c is opened. Then, by closing the contact 10a, the upward operation relay 10 is self-held, and the first escalator 5
Drives up fast.

Next, a case will be described in which the second escalator 6 is operated at high speed. As in the case of the first escalator 5, when the speed changeover switch 22 is turned to the high speed side, the power (+) - stop switch 21 - speed changeover switch 22 - contact 25b - contact 24a - relay 23 - power supply (-) circuit High speed operation relay 2
3 is energized.

Further, the first escalator 5 is already in ascending operation and the contact 10b of its ascending operation relay 10 is closed, so when the ascending operation switch 17 is pressed, the power supply (+) - stop switch 21 - ascending operation is closed. The upward operation relay 19 is energized by the circuit of switch 17 - contact 10b - contact 20b - relay 19 - power supply (-), contacts 19a to 19c are closed and contact 19d is opened. and contact 19a
By closing, the ascending operation relay 19 is self-held, and the second escalator 6 also performs a high-speed ascending operation.

Finally, in the case of the third escalator 7, similarly to the first and second escalators 5 and 6, when the speed changeover switch 31 is turned to the high speed side, the power supply (+) - stop switch 30 - changeover switch 31 - contact 34b
The high-speed operation relay 32 is energized by the -contact 33a-relay 32-power supply (-) circuit.

Further, in the second escalator 6, the contact 19c of the ascending operation relay is closed, so when the ascending operation switch 26 is pressed, the power supply (+) - stop switch 30 - ascending operation relay 26 - contact 19c - contact 2
9c - Rising operation relay 28 - The ascending operation relay 28 is energized by the power supply (-) circuit, and the contact 28
a, 29b are closed and contact 28c is opened. By closing the contact point 28a, the ascending operation relay 28 is self-held, and the third escalator 7 also performs a high-speed ascending operation.

In this way, the first to third escalators 5 to 7
When all of the escalators are in high-speed ascending operation, if the speed selector switch 13 of the first escalator 5 is switched to the low speed side, the high-speed operation relay 14 is deenergized and the contact 14a is closed, so the power supply (+) - is stopped. Switch 12 - Speed selector switch 13 - Contact 14a -
The low speed operation relay 15 is energized by the power supply (-) circuit, and the first escalator 5 is switched to low speed operation. At the same time, when contact 15b of low-speed operation relay 15 is closed, power supply (+) - stop switch 21 - contact 19b - contact 15
The speed switching relay 25 of the second escalator 6 is energized by the b-speed switching relay 25-power supply (-) circuit, so that the contact 25a is closed and the contact 25b is opened.

By opening contact 25b, high-speed operation relay 23
is deenergized and contact 23a is closed, so power (+) - stop switch 21 - contact 25a - contact 23
The low-speed operation relay 24 is energized by the a-relay 24-power supply (-) circuit, and the second escalator 6 is also switched to low-speed operation.

Furthermore, since the contact 24c of the low-speed operation relay 24 is closed, the third escalator 7 also has the power (+)-stop switch 30-contact 28b-contact 24
c-Speed switching relay 34-The speed switching relay 34 is energized by the power supply (-) circuit to close the contact 34a and open the contact 34b. Contact 34b
By opening, the high-speed operation relay 32 is deenergized and the contact 32a is closed, so the low-speed operation relay is activated by the power supply (+)-stop switch 30-contact 34a-contact 32a-low-speed operation relay 33-power supply (-) circuit. 33 is energized, and the third escalator 7 is also switched to low speed operation.

In addition, while the first to third escalators 5, to 7 are operating at high speed, the second escalator 6
When the third escalator 7 is switched to low-speed operation, the speed switching relay 34 is energized and the third escalator 7 is switched to low-speed operation, similarly to when the first escalator 5 is switched to low-speed operation. However, since the speed switching relay 16 of the first escalator 5 is not energized, the first escalator 5 continues to operate at high speed.

In addition, when the third escalator 7 is switched to low speed operation while the first to third escalators 5 to 7 are operating at high speed, the speed switching relays of the first and second escalators 5 and 6 Since both escalators 16 and 25 are not energized, the first and second escalators 5 and 6 continue to operate at high speed.

Next, a case where the first to third escalators 5 to 7 are operated downward will be described. Note that in the case of descending operation, almost the same operation as that of ascending operation is performed, so a detailed explanation will be omitted. The operation of the speed changeover switches 13, 22, 31 is the same as in the ascending operation, and the high-speed operation relays 14, 23, 32 are energized. When the descending operation switch 27 of the third escalator 7 is pressed, the descending operation relay 29 is energized, contacts 29a and 29b are closed, and contact 2
9c is opened, and the third escalator 7 operates in a high-speed downward operation.

Next, when the descending operation switch 18 of the second escalator 6 is pressed, since the contact 29b is already closed, the descending operation relay 20 is energized, the contacts 20a to 20c are closed, and the contact 20d is opened. , the second escalator 6 also operates downward at high speed.
Similarly, when the downward operation switch 9 of the first escalator 5 is pressed, the downward operation relay 11 is energized, and the first escalator 5 performs a high-speed downward operation.

In this way, when the first to third escalators 5 to 7 are all in high-speed descending operation, when the speed changeover switch 31 of the third escalator 7 is switched to low speed, the low-speed operation relay 33 is energized, and the contact 33b, the speed switching relay 25 of the second escalator 6 is energized.

Further, when the contact 25a is closed and the contact 25b is opened, the low speed operation relay 24 is energized, and when the contact 24b is closed and the speed switching relay 16 of the first escalator 5 is energized, the low speed operation relay 24 is energized. Contact 16a is closed.

Furthermore, since contact 16b is opened, low-speed operation relay 15 is energized. When the third escalator 7 is switched to low-speed operation in this way, the second and first escalators 6 and 5 are also switched to low-speed operation.

Furthermore, when the second escalator 6 is switched to low-speed operation, the first escalator 5 is switched to low-speed operation, but the third escalator 7 continues to operate at high speed because the speed switching relay 34 is not energized. Furthermore, even if the first escalator 5 is switched to low speed operation, the second and third escalators 6,
7 will be driven at high speed regardless.

In this way, when the speed of one of the escalators arranged in series and operating in a predetermined direction is switched to low speed, the other escalators that are running towards the escalator that is operating at low speed are switched to low speed. Therefore, it is possible to prevent passenger confusion and accidents at the entrance and exit of the escalator that has been switched to low speed.

Although this embodiment has been described with respect to three escalators arranged in series, the same effect can be obtained even if this embodiment is applied to a passenger conveyor such as a plurality of appropriate escalators arranged in series. That is clear.

In addition, when changing the speed, by changing the speed slowly using the slow speed change device, it is possible to prevent an accident in which passengers fall due to the impact at the time of changing the speed.

Further, in the above embodiment, the explanation has been made regarding two speeds, high speed and low speed, but the same effects as in the above embodiment can be obtained even if the conveyor is capable of operating at multiple speeds, or even at any speed.

[Effect of idea]

As explained above, this invention detects when one of these man conveyors has switched to the first operating speed in a plurality of man conveyors arranged in series and operated in a predetermined direction that can switch speeds. Then, the other passenger conveyors operating towards this passenger conveyor are switched from the second operating speed to the first operating speed, so that the passenger conveyor that has been switched to the first operating speed is This has the effect of preventing confusion caused by passengers being carried in different directions.
