Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor activation alarm device having a display for displaying the operation of a safety device switch.

[0002]

2. Description of the Related Art Generally, a passenger conveyor such as an escalator or a moving walkway is provided with a large number of safety device switches for emergency stop of the passenger conveyor in case of an abnormality for passenger safety. Such safety device switches include manual reset switches and automatic reset switches. The former operates due to equipment failure, etc., and after being repaired by a maintenance technician, a sufficient safety check is performed and then manually restored.The latter operates due to a temporary abnormality such as carelessness of passengers, It is automatically restored if the cause of the operation is removed.

However, even if the safety device switch detects an abnormality and the operation of the passenger conveyor is stopped, it is not possible to know which of the many switches has operated.
The general manager cannot determine whether the passenger conveyor can be restarted, and even if the switch is automatically reset, the maintenance engineer will unnecessarily extend the stop time of the passenger conveyor. .

Therefore, for example, Japanese Patent Publication No. 59-4358 discloses a start alarm device for informing the general manager whether or not the passenger conveyor stopped by the operation of the safety device switch can be restarted. . This device
The balustrade of the passenger conveyor is provided with an indicator light which is turned off when the passenger conveyor is stopped by the operation of the safety device switch and is turned on when the safety device switch is restored.

[0005]

In the conventional passenger conveyor start-up alarm device, whether or not the passenger conveyor can be restarted can be determined by blinking the indicator light.
The general manager looked at only the indicator light, judged that it could be restarted if the indicator light was on, and restarted the passenger conveyor. However, an automatic reset type safety device switch,
For example, in the switch of the skirt guard safety device, even if a foreign object is caught between the step and the skirt guard, the switch automatically returns if the caught foreign object moves from the position of the switch. In such cases,
Since the indicator lamp lights up despite the presence of foreign matter, the general administrator may overconfidently display the indicator lamp and fail to sufficiently check the safety of the passenger conveyor and restart the passenger conveyor. is there. As a result, there is a problem in that the residual foreign matter may damage the equipment of the passenger conveyor.

The present invention has been made to solve the above problems, and restarts the passenger conveyor stopped by the operation of the safety device switch without the safety confirmation by the general manager. It is an object of the present invention to provide an activation alarm device for a passenger conveyor that can prevent the above.

[0007]

According to another aspect of the present invention, there is provided an alarm device for activating a passenger conveyor, wherein the display continues to display until the activating switch of the passenger conveyor is closed, even if the safety device switch is restored. When the activation switch is closed, the display is stopped if the safety device switch is restored, and the display is continued if the safety device switch is not restored.

In the passenger conveyor activation alarm device according to the second aspect of the present invention, the indicator displays differently when the manual reset switch is operated and when the automatic reset switch is operated, and Even if the safety device switch is restored, the display continues until the activation switch of the passenger conveyor is closed.When the activation switch is closed, if the safety device switch is restored, the display is stopped and the safety device switch is restored. If not, the display is further continued.

In the passenger conveyor activation alarm device according to the third aspect of the present invention, even if the safety device switch is restored, the indicator continues to display until the passenger conveyor activation switch is closed, and the activation switch is closed. At this time, if the safety device switch is restored, the display is stopped, and if the safety device switch is not restored, the display is continued and the start switch is closed when the safety device switch is restored. In this case, when the passenger conveyor is driven by a predetermined amount, the passenger conveyor is automatically stopped.

[0010]

According to the present invention, even if the safety device switch is restored, the display continues to display until the activation switch of the passenger conveyor is closed, thereby prompting the general manager to confirm safety before closing the activation switch.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. Example 1. FIG. 1 is a flow chart for explaining the operation of a passenger conveyor activation alarm device according to an embodiment of the invention of claim 1, FIG. 2 is a front view showing an operation panel including the activation alarm device of FIG. 1, and FIG. FIG. 3 is a partial perspective view of a passenger conveyor showing an arrangement example of the operation panel of FIG.

In FIGS. 2 and 3, 1 is an operation panel provided below the balustrade 10 at the entrance / exit of the passenger conveyor, 2 is a start switch provided on the operation panel 1, and 3 is provided on the operation panel 1. The stop switch 4 is an indicator lamp provided in the center of the operation panel 1 as an indicator of a start alarm device.

Next, the operation of the activation alarm device of the first embodiment will be described with reference to FIG. When the passenger conveyor is stopped for some reason, this activation alarm device first determines whether or not it is due to the safety device switch (S
1). Then, when the safety device switch is in the operating state, the indicator lamp 4 is turned on (S2), and the indicator lamp 4 is kept as it is until the start switch 2 is closed regardless of whether the safety device switch is restored or not. Continue to light.

On the other hand, when the passenger conveyor is stopped, the general manager confirms the lighting of the indicator lamp 4 and confirms the safety of the passenger conveyor (external inspection). At this time, if the cause of the operation of the safety device switch is found, it is removed. In this way, when the safety is confirmed, the general administrator puts the activation switch 2 into the closed state.

The activation alarm device determines whether or not the activation switch 2 is closed (S3), confirms the closed state, and then determines whether or not the safety device switch is in the reset state (S4). Here, if the safety device switch is restored, the indicator lamp 4 is turned off (S5), and the passenger conveyor is restarted. If the safety device switch has not been returned, the indicator lamp 4 will continue to light up, so the general manager will request the maintenance engineer for repair. Also in this case, after the cause of the operation is removed and the safety device switch is restored and then the start switch 2 is closed, the indicator lamp 4 is turned off and the passenger conveyor is restarted.

In such a passenger conveyor activation alarm device, even if the safety device switch is automatically restored, the indicator lamp 4 continues to be illuminated until the activation switch 2 is closed.
The general administrator cannot rely on the indicator light 4, and therefore will perform a sufficient safety check before closing the activation switch 2. As a result, the device of the passenger conveyor is prevented from being damaged without being restarted without removing the cause of the stop.

Example 2. FIG. 4 is a flow chart illustrating the operation of the passenger conveyor activation alarm device according to the second embodiment of the invention. The activation alarm device of the second embodiment uses the same operation panel 1 as that of FIG. .

Next, the operation will be described. When the passenger conveyor is stopped for some reason, it is first determined whether or not it is due to the safety device switch (S1).
When the safety device switch is in the operating state, the activation alarm device of the second embodiment determines whether the operated safety device switch is of the automatic reset type or the manual reset type (S6). As a result, the indicator light 4 is turned on if it is the automatic restoration type (S2), and the indicator light 4 is blinked if it is the manual restoration type. The lighting and blinking of the indicator light 4 are continued until the start switch 2 is closed, regardless of whether the safety device switch is restored or not.

On the other hand, the general manager confirms the indicator lamp 4 when the passenger conveyor is stopped. If the indicator lamp 4 is lit, after confirming the safety of the passenger conveyor, the start switch 2 is closed. Put in a state. If the indicator light 4 is blinking, a maintenance engineer is requested to repair the safety device switch, and then the start switch 2 is closed.

The activation alarm device determines whether the activation switch 2 is closed (S3), and when the closed state is confirmed, it is then determined whether the safety device switch is in the reset state (S4). Here, if the safety device switch is restored, the indicator lamp 4 is turned off (S5), and the passenger conveyor is restarted.

In such a passenger conveyor start alarm device, even if the safety device switch is automatically restored, the indicator lamp 4 continues to light until the start switch 2 is closed.
The general manager does not neglect the safety confirmation. In addition, when the switch of the manual reset type operates, the indicator lamp 4 is made to blink in distinction from the case of the automatic reset type, so it is not necessary to check the safety or turn on the start switch. The maintenance engineer can be called immediately, and the stop time of the passenger conveyor can be shortened.

Example 3. FIG. 5 is a flow chart for explaining the operation of the passenger conveyor activation alarm device according to the third embodiment of the invention. The activation alarm device according to the third embodiment is configured to automatically stop (S8) when the passenger conveyor is driven by a predetermined amount (for example, 50 mm) when the passenger conveyor is restarted. Other operations are the same as those in the second embodiment.

As described above, when the passenger conveyor is stopped by the operation of the automatic reset type safety device switch,
The general manager confirms the safety of the appearance of the passenger conveyor by observing the lighting of the indicator light 4. However, even if this safety check is performed, there is a possibility that the cause of operation of the safety device switch cannot be found or may be overlooked.

For example, when a foreign substance is caught between the step and the skirt guard, and the foreign substance passes through the safety device step and the operated switch is restored, the passenger conveyor is not removed. Rebooting may result in the worst case of damaging equipment on the passenger conveyor. This is as described in the problems of the prior art. However, as in the case of the third embodiment, by slightly moving the passenger conveyor to stop (swing), frictional noise between the foreign matter caught and the skirt guard,
The general manager can notice the presence of foreign matter, detect the foreign matter, and avoid damage to the equipment.

Example 4. FIG. 6 is a flow chart for explaining the operation of the passenger conveyor activation alarm device according to another embodiment of the invention of claim 3. In addition to the operation of the device according to the third embodiment, the activation alarm device according to the fourth embodiment determines whether or not the safety device switch is kept in the reset state after the passenger conveyor is moved slightly (S8). . And
When the manual reset switch operates or when the safety device switch operates again after the inching, the indicator lamp 4 is blinked (S7) and the passenger conveyor is locked so that it cannot be restarted (S10). Other operations are the same as in the third embodiment.

Normally, when the manual reset type switch operates or when the safety device switch operates again after the inching,
It is not desirable to try to unnecessarily restart the passenger conveyor because it requires repair by a maintenance engineer. In particular, when the safety device switch is activated again after the inching, despite having performed sufficient safety confirmation,
Repeating the operation flow as shown in FIG. 5 many times is not preferable from the viewpoint of protecting the device. In view of this, in the fourth embodiment, the indicator lamp 4 is made to blink to notify the need for repair by the maintenance engineer, and the passenger conveyor is locked so that the general administrator cannot accidentally restart the passenger conveyor. . This prevents damage to the passenger conveyor equipment.

In each of the above embodiments, the indicator lamp 4 is shown as one that simply blinks, but the names of the operating safety devices (GOV, SCS, SRS, HGS, CRS, SS) are shown.
(S, E stop, HSS, etc.) or position can be displayed, and it is possible to immediately understand whether the general administrator should perform safety confirmation of the car, so that the stop time of the passenger conveyor can be shortened. Also in this case, the manual reset type and the automatic reset type may be displayed separately.

Further, in the above-mentioned embodiment, when the operated safety device switch is of the automatic resetting type, it is lit, and in the case of the manual resetting type, it is blinking to distinguish between the two, but of course they may be reversed. The color to be displayed may be changed, or a dedicated display device may be provided for each to distinguish the colors.

Example 5. FIG. 7 shows an example in which the operated safety device name can be displayed using the indicator lamp 5 in which a plurality of 8-segment display bodies are arranged. In this case as well, it is possible to distinguish whether the operated switch is an automatic reset type or a manual reset type by lighting and blinking. Further, when the manual reset switch is operated, NG or the like may simply be displayed. Further, in addition to the indicator lamp 5 for displaying the safety device name, another indicator lamp for distinguishing between the automatic reset type and the manual reset type may be provided.

Example 6. FIG. 8 shows another example of the indicator lamp 5, which includes three display bodies 5a for displaying the name of the operated safety device (for example, CRS) and a display body 5b for displaying the position of the operated safety device by a number or the like. It has and. Further, the display body 5a is adapted to light up and display the safety device name when the manual reset type switch is operated, and to blink the safety device name when the automatic reset type switch is operated.
According to such an indicator light 5, the cause of the operation of the safety device switch can be removed more quickly.

Example 7. FIG. 9 shows an example in which the position of the operated safety device can be displayed by using the display device 6 which displays characters by liquid crystal or the like. As described above, the display device is not limited to the indicator light.

[0032]

As described above, in the passenger conveyor activation alarm device according to the first aspect of the present invention, once the safety device switch is activated, the passenger conveyor activation switch is closed even if the safety device switch is restored. Since the display on the display continues, it is possible to prevent the general administrator from restarting the passenger conveyor stopped by the operation of the safety device switch without confirming the safety. It is possible to prevent the equipment of the passenger conveyor from being damaged by the foreign matter.

The passenger conveyor activation alarm device according to the second aspect of the present invention provides different indications when the manual reset switch is in operation and when the automatic reset switch is in operation. In addition to the effects of the invention, when a manually-reset type switch operates, without performing unnecessary safety confirmation,
The effect is that the maintenance technician can be called promptly and the stop time of the passenger conveyor can be shortened.

Further, in the passenger conveyor activation alarm device according to the third aspect of the present invention, if the activation switch is closed while the safety device switch is returning, the passenger conveyor is automatically stopped after a predetermined amount is driven. As a result, in addition to the effect of the invention of claim 1, the cause of the operation of the safety device switch can be found more reliably, and the damage to the equipment of the passenger conveyor can be prevented more reliably. Play.
