How to Operate a Multi-Speed Passenger Conveyor {OPERATION MANIPULATING METHOD FOR PASSENGER CONVEYER CORRESPONDING MULTISTEP SPEED}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving operation method of a multi-stage speed response passenger conveyor such as an escalator or a moving walkway.

Conventionally, in a multistage speed switch type passenger conveyor, operation is started by operating a start switch after operating a speed selection switch. As a result, the starting method is different for a general one-speed passenger conveyor and a multi-speed passenger conveyor, and the operator uses two types of starting methods when starting at a place where the multi-speed passenger conveyor and the one-speed passenger conveyor are mixed. It is necessary to understand, and it is realistic to start with a different starting method for each device.

However, when the driving speed is incorrectly started, it is necessary to stop the passenger conveyor once, restart, and change the driving speed.

In addition, when providing a plurality of speed selection switches, it is necessary to use an automatic return type as the speed selection switch. In this case, after selecting the speed, safety is confirmed and the start switch is operated. Therefore, it is conceivable to incorrectly start the operation speed due to the memory difference.

In addition, when the input holding type is used for the speed selection switch, the operation speed is less likely to be wrong. However, since the speed selection switch cannot be provided in plural, the speed selection operation can only be performed in one place, and the operation is performed on only one of the upper and lower floors. Can not.

(1st embodiment)

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings.

1 to 6 are diagrams showing a first embodiment of a driving operation method of a passenger conveyor according to the present invention.

First, the outline of the multistage speed switch type passenger conveyor 30 will be described with reference to FIG. As shown in Fig. 1, the passenger conveyor 30 is capable of switching at multiple speeds, and is capable of driving up or down. The passenger conveyor 30 is a handrail 36, a step chain 33 disposed below the handrail 36, to which a plurality of step 32 are attached, and a drive sprocket 34 for driving the step chain 33. ) And a driven sprocket 35 that engages with the step chain 33.

The drive sprocket 34 is driven by the motor 9, which is connected to the inverter circuit 2. In addition, the inverter circuit 2 is connected to the inverter control unit 3, and the inverter control unit 3 is connected to the control unit 4.

Moreover, the operation panel 6, the display apparatus 7, and the speaker 8 are attached to the handrail 36 or its vicinity. These operation panels 6 and the display device 7 are connected to the control device 4, respectively. In addition, the speaker 8 is connected to the control device 4 via the audio guide device 5. Moreover, the control part 4 and the inverter circuit 2 are connected to the power supply via the circuit breaker 1 for main circuits.

Moreover, as shown in FIG. 2, the operation panel 6 is provided with the key type speed change switch 10, the start switch 11, and the stop buzzer switch 12 in the substantially longitudinal direction, respectively. Further, a push button type emergency stop switch is disposed above the start switch 10. In addition, the push-button speed switching switch 14 may be provided instead of the speed switching switch 10. Moreover, the speed switching switch 10, the start switch 11, and the stop buzzer switch 12 may be provided in the horizontal direction.

Next, the driving operation method of the multi-stage speed switch type passenger conveyor according to the present invention will be described with reference to Figs. 3, the driving operation method of the 1-speed passenger conveyor is shown for comparison.

The frequency corresponding to each multi-stage speed is preset in the inverter control part 3. The control unit 4 also sets a reference speed (hereinafter referred to as reference speed).

As shown in Fig. 4, when the operator starts the multi-stage speed switchable passenger conveyor 30, the buzzer sounds with the stop buzzer switch 12 of the operation panel 6, and then the start switch (start SW) ( By 11), an arbitrary driving direction, for example, a rising operation or a falling operation, is determined and started. At this time, the buzzer ringing step by the stop buzzer switch 12 and the starting step 13 by the starting SW are the same as in the case of starting the one-speed passenger conveyor shown in FIG.

Next, the control unit 4 receives a start signal from the start switch 11 of the operation panel 6, and the control unit 4 outputs an operation command 21a to the inverter control unit 3. At that time, the control unit 4 also outputs the speed command 21 at the reference speed set in advance by the inverter control unit 3. The signal from the inverter control section 3 is transferred to the inverter circuit 2, the inverter circuit 2 starts the output and accelerates the motor 9 until the frequency of the reference speed is reached, and the passenger conveyor 30 Run at a reference speed (eg 30 m / min). At this point, the passenger conveyor 30 is started up.

Thereafter, when the speed switching switch 10 of the operation panel 6, which is a self-return type switch, is operated to the acceleration side, the speed command 21 from the controller 4 is switched and the speed is accelerated by one step. On the other hand, when the speed switching switch 10 is operated to the deceleration side, the speed command 21 from the control unit 4 is switched to decelerate by one step. In this way, the operator can select the arbitrary speed by operating the speed switching switch 10 after changing the speed by one step, and thus the speed change is completed.

Thereafter, the buzzer is sounded by the stop buzzer switch 12, and then the passenger conveyor 30 is stopped by the stop buzzer switch 12.

Next, the operation operation method in the case where the speed change switch is the push button type speed change switch 14 will be described with reference to FIG.

The speed switching switch 14 is provided with high-speed, medium-speed, and low-speed push buttons, and a reference speed (for example, medium speed), which is a reference in advance, is set. In Fig. 6, similarly to the case of Fig. 4 described above, the buzzer ringing step by the stop buzzer switch 12 and the starting step by the starting SW without operating the push-button speed switching switch 14 at the time of starting. The startup is completed by (13). Thereafter, the pushbutton speed changeover switch 14 is operated to select an arbitrary speed, for example, high speed or low speed.

In Fig. 6, the other steps are substantially the same as the driving operation method shown in Fig. 4.

As described above, according to the present embodiment, the passenger conveyor 30 can be started by the same operation as the one-speed passenger conveyor even in the multi-stage speed switchable passenger conveyor. It is not necessary to start the system, and the unification of the starting operation can be achieved.

In addition, the difference in operation between the single-speed passenger conveyor and the multistage speed switchable passenger conveyor is that the speed change operation is not necessary for the single-speed passenger conveyor, while the speed change operation needs to be performed after the completion of the startup. That's the point. Therefore, it is possible to prevent misoperation easily by understanding the difference in operation method. In addition, since the inverter control section 3 controls the inverter circuit 2 and the motor 9 accelerates and decelerates at a safe acceleration / deceleration speed, safety can be ensured even if the speed is changed during operation.

In addition, since acceleration and deceleration are carried out step by step with the self-return type speed switching switch 10, even if the number of switching speed stages increases, there is no need to change the operation method, and it is possible to cope with an operation method such as a single speed conveyor. In addition, even when the push-button speed changeover switch 14 is provided, the same operation can be performed without changing the operation method. In addition, since the speed is changed during the operation of the passenger conveyor 30, even if the driving speed is wrong due to a misoperation or the like, there is no effort to stop once, and the driving speed can be corrected only by the operation of the speed switching switches 10 and 14. have.

(2nd embodiment)

Next, a second embodiment of the present invention will be described with reference to Figs.

7 and 8, in the multi-stage speed switch type passenger conveyor 30, a driving operation for invalidating the speed selection operation during acceleration during startup, speed switching and within a predetermined time after speed switching is completed. It is a method and another process is substantially the same as 1st Embodiment shown in FIGS.

As shown in Fig. 7, in the second embodiment, after the startup operation is performed, the acceleration during startup until the reference speed is reached 15 is performed, and the acceleration is performed until the speed change is completed (16). ), The speed switching operation is performed by operating the speed switching switches 10 and 14 of the operation panel 6 during the deceleration 17 until the speed change is completed and the time change 18 after the speed change is completed. Even if it did, the speed was not switched.

As shown in Fig. 1 and Fig. 8, a signal when the frequency output from the inverter circuit 2 coincides with a preset frequency, that is, the frequency coincidence signal 22 is transferred from the inverter controller 3 to the controller 4. Is output. The control part 4 judges that the speed is changing based on this frequency coincidence signal 22, and invalidates the signal from the speed switching switches 10 and 14 of the operation panel 6. In addition, the controller 4 determines the speed coincidence based on the frequency coincidence signal 22, and then controls the signal from the speed changeover switches 10 and 14 to be invalid for a certain time.

In addition, although the control part 4 invalidates the signal from the speed change switches 10 and 14 based on the frequency coincidence signal 22, the control part 4 also speeds up by the sensor or the timer which judges the speed. The signal from the speed switching switches 10 and 14 may be invalidated by judging the change of.

As described above, according to the present embodiment, when the operator incorrectly manipulates the speed changeover switches 10 and 14 twice by invalidating the operation signal from the speed changeover switches 10 and 14 during the speed change. In addition, malfunctions such as the case where the control unit 4 reads the signal twice in one operation due to the contact problem of the switches 10 and 14 can be prevented. In addition, a sudden speed change can be prevented by switching the speed stage into two or three steps at once, or by decelerating and operating during acceleration. In addition, by invalidating the operation signal from the speed change switches 10 and 14 after completion of the speed change, the speed change becomes invalid until the speed is stabilized, and the user may feel concern about the riding comfort or anxiety. It can prevent.

(Third embodiment)

Next, a third embodiment of the present invention will be described with reference to FIG. In the embodiment shown in FIG. 9, the speed selection range which can be switched in the passenger conveyor 30 is changed into a rising operation time and a falling operation time, and other processes are substantially the same as those of the first embodiment shown in FIGS. Do.

As shown in Figs. 1 and 9, when the passenger conveyor 30 is in the lower driving (DN operation) without operating the lowering high speed switch 19, the upper limit of the speed during the lowering operation is switched to switch the case of the rising operation. In the case of and descent operation, the speed selection range is different. Then, in the lowering operation, when the passenger conveyor 30 reaches a certain speed, the control unit 4 limits the speed so that the speed is not accelerated even when the speed switching switches 10 and 14 perform the acceleration operation.

That is, the speed upper limit value at the time of descent operation is preset in the control part 4. When acceleration operation is performed by the speed switching switches 10 and 14 during the lowering operation, the control unit 4 determines whether the speed command 21 to the inverter control unit 3 has reached the upper speed limit during the lowering operation. When the control unit 4 determines that the speed command 21 has reached the upper limit of speed, even if there is an acceleration signal input from the speed switching switches 10 and 14 of the operation panel 6 to the control unit 4, the control unit 4 Determines that the acceleration is invalid and maintains the current speed of the passenger conveyor 30 as it is at the current speed command 21.

In addition, the upper speed limit during the lowering operation may be released by operating the lowering high speed switch 19. In this case, the control unit 4 does not judge the upper limit value of the speed during the lowering operation, but the rising operation time even when the speed command 21 of the speed upper limit value during the lowering operation is preset to the inverter control unit 3. As with full speed singular operation. Thus, the upper limit of the speed at the time of descent operation can be switched by operation of the falling high speed switch 19 according to a use.

9, other processes are substantially the same as those of the first embodiment shown in FIGS.

According to this embodiment, in the case of the descent driving, as compared with the rising driving, the passenger's field of view becomes wider. Therefore, when the passenger conveyor 30 is driven at a high speed, it is conceivable to give a fear to the passenger. In such a case, by providing the falling high speed switch 19, it is possible to disable the high speed operation during the falling operation. It is also conceivable that the safety device operates during the high speed driving of the descent driving so that the passenger conveyor 30 suddenly stops. In this case, the passenger conveyor 30 is stopped at a safe stopping distance. However, when descending, the passenger conveyor 30 is discharged downward. Occurs. According to this embodiment, by operating the falling high speed switch 19, it is possible to arbitrarily select the speed upper limit of the falling operation to prevent the high speed operation during the falling operation.

(4th embodiment)

Next, a fourth embodiment of the present invention will be described.

In the fourth embodiment, the speed is changed in accordance with the speed switching of the passenger conveyor, or the voice announcement broadcast prompting attention when changing the speed is performed. The other steps are substantially the same as those in the first embodiment shown in Figs.

1, in the case where the operator performs the speed switching operation and the control unit 4 receives the speed change signal from the speed switching switches 10 and 14 of the operation panel 6, the voice guide device from the control unit 4 ( The broadcast command 23 is outputted to 5). The voice guidance apparatus 5 starts broadcasting from the speaker 8 so that the speed changes.

As an example of broadcasting, the speed becomes faster. Please note. ”Or“ Speed will increase. Please hold the railing. ” When the voice broadcast from the speaker 8 is terminated, the voice guidance end signal 24 is transmitted from the voice guide device 5 to the controller 4. The control unit 4 receives the voice guidance end signal 24 and then outputs the speed command 21 to the inverter control unit 3 to convert the frequency by the inverter circuit 2 to change the speed of the motor 9. Initiate.

According to the present embodiment, the user using the passenger conveyor 30 can cope with the speed change by prompting attention by the voice guidance by the speaker 8 before the speed change in accordance with the speed change. As a result, even if the speed changes, the user does not panic. Further, even when the operation panel 6 is far away and the speed is changed from a long distance, attention can be prompted when the speed is switched by the attention broadcast so that the speed can be safely changed.

(5th embodiment)

Next, a fifth embodiment of the present invention will be described with reference to FIGS. 10 and 11.

10 and 11, the speed display is performed by the display device in accordance with the change in the speed during the operation operation of the multi-stage speed switch type passenger conveyor 30. FIG. 10 and 11, the other steps are substantially the same as those of the first embodiment shown in Figs.

10 and 11, when the operator performs the speed switching operation and the control unit 4 receives the speed change signal from the speed switching switches 10 and 14 of the operation panel 6, the control unit 4 controls the inverter. The same signal as the speed command 21 output to (3) is output to the display device 7. The display device 7 changes the display content 20 of the display device 7 by switching the signal transferred from the control unit 4.

When the display is changed during speed change, the control unit 4 receives the frequency coincidence signal 22 from the inverter control unit 3 and outputs it to the display device 7 as a signal being speed change.

FIG. 10 shows an example of the installation place of the display device 7, and when the display device 7 is installed in the vicinity of the operation panel 6, the speed switching switches 10 and 14 of the operation panel 6 are operated. Can be operated while checking the speed.

In addition, as shown in FIG. 11, the display apparatus 7 may display "in change" during the speed change as the display content 20. In addition, as described in the second embodiment, when the switching operation is invalidated during the speed change, it can be confirmed by the display content 20 "changing" that the operation becomes invalid.

According to the present embodiment, by providing the display device 7, the operator can visually check the current driving state by visually confirming the operation, which leads to the prevention of erroneous operation during speed switching. In addition, in the case of the multi-speed passenger conveyor which invalidates the speed switching operation during the speed change, it is possible to determine that the speed change is impossible by the display device 7, which is an operation method that is easy for the operator to understand.

According to the present invention as described above, in the multi-stage speed switch type passenger conveyor, it is possible to start by the same operation as the general one-speed passenger conveyor. For this reason, the operator does not need to understand two types of operation methods, and the operation can be simplified.

In the case of switching the speed, the switching operation after the completion of startup can reduce the effort to stop once as in the prior art. In addition, in the case of a large number of switching speed stages, the use of the input holding key switch has a limit in the switching speed stage. However, by using the self-returning key switch, the speed can be accelerated or decelerated step by step to select an arbitrary speed. Even if the number of steps increases, the operation can be easily performed.

Further, even when a plurality of automatic return type speed change switches are provided, the operation can be easily performed similarly, and the speed change operation can be easily performed.

In addition, by setting the upper limit of the speed at the time of the descent operation to limit the high speed operation at the time of the descent operation by the speed change switch, the safety can be improved at the place where the elderly or the child of the child are many in the installation environment.

In addition, by providing voice guidance at the speed change, the safety of the user can be improved, and the embarrassment and anxiety of the user can be reduced during the speed change.

In addition, by providing a display device that displays the driving speed in the vicinity of the operation panel, the operability for the operator can be improved and the operation can be simplified.
