2. Description of the Related Art Conventionally, many proposals have been made as a moving handrail cleaning device for a passenger conveyor. As one of such devices, as shown in JP-A-5-24782, a belt-shaped cleaning cloth is formed into a roll. There has been proposed an apparatus in which a cleaning cloth is wound from a roll at predetermined time intervals, and the cleaning cloth is pressed against the surface of the moving handrail for a set time to wipe off oil and dirt attached to the moving handrail. However, recently, there has been proposed a cleaning cloth which uses a cleaning paper due to an increase in cost, etc., and which does not slide only for a set time but constantly slides while the passenger conveyor is in operation.

[0003]

In the above-mentioned proposal, it is conceivable that the cleaning paper is always slid in contact with the cleaning paper and is cut off in the middle because the paper is paper. When the passenger conveyor operates in this state, the presser pressing the cleaning paper comes into sliding contact with the surface of the moving handrail. was there.

A first object of the present invention is to provide an apparatus for cleaning a moving handrail of a passenger conveyor, which eliminates a state in which cleaning is impossible due to cutting of cleaning paper.

A second object of the present invention is to provide an apparatus for cleaning a moving handrail of a passenger conveyor which prevents a pressing element from directly contacting the surface of the moving handrail when cutting the cleaning paper.

[0006]

The first object of the present invention is to provide a cleaning roll wound with a cleaning paper, and a cleaning paper wound at a predetermined distance from the roll and provided at a predetermined distance from the roll. A take-up roller, a pressing means provided between the take-up roller and the roller body for pressing the cleaning paper against the surface of the moving handrail, and detecting the cut when the cleaning paper is cut. Notification means for notifying the user.

That is, when the cleaning paper is cut off, the notifying means operates, the cutting of the cleaning paper can be known, the cleaning paper can be immediately set in a correct state, and the state in which cleaning cannot be performed can be quickly eliminated.

A second object is to detect the cutting of the cleaning paper,
This is achieved by providing means for stopping the operation of the pressing means.

That is, since the operation of the pressing means is stopped,
The pressing element does not slide on the surface of the moving handrail, and wear of the pressing element and damage to the surface of the moving handrail can be prevented.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a passenger conveyor equipped with a passenger conveyor moving handrail cleaning device according to an embodiment of the present invention.

The moving handrail 1 is configured to be movable along a guide 2, and moves in synchronization with an endless step (not shown). A moving handrail cleaning device 3 is provided at a portion facing the surface of the moving handrail 1, and details of the moving handrail cleaning device 3 are shown in FIG.

FIG. 2 is an enlarged block diagram showing a main part of FIG.

A speed detecting means 6 is provided at a free end of a rotatable lever 5 and the speed detecting means 6 is urged in a counterclockwise direction by a spring 4 provided at the free end to move the speed detecting means 6 to the moving handrail 1. The speed detecting means 6 is configured to detect the movement of the moving handrail 1 as a speed. The speed detecting means 6 is connected to an operating means 8 via a switch 7 which opens and closes in conjunction with a starter switch (not shown) of the passenger conveyor, and the operation of the pressing means 9 is permitted by an output of the operating means 8. It is configured as follows. In addition, the speed detecting means 6 is provided with a releasing means 1 via a switch 10 which opens and closes in conjunction with an activation switch of the passenger conveyor.
1 connected. These pressing means 9 and releasing means 11
The movable member 12 that moves up and down is provided with a pressing element 14 via a spring 13. A cleaning paper 15 made of paper impregnated with a polishing agent such as silicon is disposed between the contact portion of the pressing element 14 and the handrail 1. One end of the cleaning paper 15 is wound on the roll body 16 and the other end is wound on the roll body 16. It is wound around the take-up roller 17. A brake device 18 is connected to the roll body 16, and a rotating means 19 is connected to the winding roller 17.

Numerals 20 and 21 denote detectors for emitting a beam to the cleaning paper 15 and receiving the reflected light of the cleaning paper 15. The cleaning paper 15 is not cut while receiving the reflected light. When the reflected light is no longer received, cutting is detected. Reference numeral 22 denotes a switch that opens and closes in conjunction with the cut detectors 20 and 21. When the switch 22 is turned on, that is, when the cleaning paper 15 is cut, the release unit 11 and the notification unit 23 operate. I have.

Next, a cleaning operation by the moving handrail cleaning device 3 will be described.

When the starter switch of the passenger conveyor is turned on and the moving handrail 1 is operated, the speed detecting means 6 detects that the moving speed has reached 70% of the rated speed by the judging circuit 6a. At this time, since the switch 7 linked to the start switch is closed, the operating means 8 operates. The actuating means 8 permits the operation of the pressing means 9. If the cleaning operation start command has been given to the moving handrail cleaning device 3 by this time, the pressing means 9 will be moved to the movable member 12.
The presser 14 is pushed upward in the drawing via the spring 13 and the cleaning paper 15 is pressed against the surface of the moving handrail 1 with a predetermined pressing force. At this time, since the moving handrail 1 has already been operated, the polishing paper 15 is pressed to apply a polishing agent to the surface, and at the same time, wipes off oil and dirt attached to the surface.

When the moving handrail 1 has moved a predetermined distance and the cleaning operation has been completed, and the activation switch of the passenger conveyor is turned off, the detection circuit 6a detects that the speed of the moving handrail 1 is 70% of the rated speed.
Detects when: At this time, since the switch 10 linked to the start switch is already in the OFF state, the release means 11 is activated, and the release means 11 is
And the presser 14 is lowered via the spring 13. Therefore,
The pressing force on the moving handrail 1 with respect to the cleaning paper 15 is released, and when the moving handrail 1 operates again next time,
The pressing force of the cleaning paper 15 on the moving handrail 1 has been removed.

When the pressing force is released, the cleaning paper 15 is separated from the moving handrail 1, but it is conceivable that the cleaning paper 15 may be in a state where both are adhered. However, since the pressing force has already been released, it is easy to separate the pressing force. For example,
When the brake device 18 is released and the rotating means 19 is rotated clockwise, the used cleaning paper 15 is taken up by the take-up roller 17 while new cleaning paper 15 is sent out from the roll body 16 side.
The cleaning paper 15 wound on the side and adhered to the moving handrail 1 at the time of the feeding operation is separated. In another mode of use, the rotating means 19 while the brake device 18 is operated.
By moving the handrail slightly, the moving handrail 1
It is also possible to separate the cleaning paper 15 adhered to the sheet. Further, the next time the moving handrail is moved to the left, the brake device 18 is operated so that the moving handrail 1
It is also possible to separate the cleaning paper 15 adhered to the sheet. In still another embodiment, the pressing means 14 is
When the roller is driven downward, the roll body 16 and the winding roller 1
7 may also be driven downward to separate the cleaning paper 15 adhered to the moving handrail 1. In any case, at least until the stopped moving handrail 1 is restarted, the moving handrail 1 is removed from the cleaning paper 1.
What is necessary is just to comprise the separation means which separates 5. If the releasing means 11 can also serve as the separating means as described above, the releasing means 11 also releases the pressing force of the pressing means 9 on the cleaning paper 15 at least until the stopped moving handrail 1 is operated again. It may be configured as follows.

Therefore, when the stopped moving handrail 1 is operated again, the pressing force of the pressing means 9 on the cleaning paper 15 is released at this time, so that the cleaning paper 15 is not damaged by the moving handrail 15 which has started to operate. The cleaning can be prevented and stable cleaning can be performed for a long time. Thereafter, the brake device 18 is released, and the rotating means 19 is rotated clockwise, and the unused portion of the cleaning paper 15 is sent out from the roll body 16 while the used portion of the cleaning paper 15 is wound around the take-up roller 17. And prepare for the next cleaning operation.

Further, when the cleaning paper 15 is cut at the point A, the switch 22 is turned on because there is no reflected light from the cut detector 21. As a result, the release means 11 operates,
The presser 14 is lowered. At the same time, the notification means 23 operates,
It notifies the outside that the cleaning paper 15 has been cut. That is, an LED lamp or the like installed at a portion visible from the outside is turned on, or a buzzer sounds to notify the user.

Thus, when the cleaning paper 15 is cut,
Since the disconnection is reported, it is possible to respond immediately and eliminate the problem of inability to clean. Further, when the cleaning paper 15 is cut, the pressing element 14 is immediately pressed down, so that the pressing element 1
The wear of the presser 14 accompanying the sliding contact of No. 4 and the occurrence of scratches on the moving handrail can be prevented.

In this embodiment, the cutting detectors 20 and 21 using beams are provided to detect the cutting of the cleaning paper 15, but the motor runs idle due to a change in the current of the motor of the rotating means 19, for example, the cutting of the cleaning paper 15. Alternatively, it may be detected from a change in current resulting from the operation.

[0024]

According to the present invention, the state in which cleaning cannot be performed due to cutting of the cleaning paper can be quickly eliminated. Further, when cutting the cleaning paper, the pressing element is lowered to prevent sliding contact with the moving handrail, so that wear of the pressing element and damage to the moving handrail can be prevented.
