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 of the passenger conveyor, and is configured such that an operation of the pressing means 9 is permitted by an output of the operating means 8. I have. The speed detecting means 6 is connected to the releasing means 11 via a switch 10 which opens and closes in conjunction with a starter switch of the passenger conveyor. The movable member 12 that moves up and down by the pressing means 9 and the releasing means 11 is provided with a contact portion 14 via a spring 13. Between the contact portion 14 and the moving handrail 1,
A cleaning body 15 made of paper or nonwoven fabric impregnated with a polishing agent such as silicon is disposed, and both ends of the cleaning body 15 are wound around rotating shafts 16 and 17, respectively. Rotating shaft 16
Is connected to a brake device 18, and the rotating shaft 17 is connected to rotating means 19, respectively.

Next, the 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 contact portion 14 is pushed upward in the drawing via the spring 13 and the cleaning body 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 body 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 start 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 lowers the contact portion 14 via the movable portion 12 and the spring 13. Therefore, the pressing force on the moving handrail 1 with respect to the cleaning body 15 is released, and when the moving handrail 1 is operated again, the pressing force of the cleaning body 15 on the moving handrail 1 is removed. Will be.

When the pressing force is released, the cleaning body 15 is separated from the moving handrail 1, but it is conceivable that the cleaning body 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 body 15 is wound up around the rotation shaft 17 while a new cleaning body 15 is fed out from the rotation shaft 16 side. At this time, the cleaning body 15 adhered to the moving handrail 1 is separated. Further, in another usage mode, the cleaning body 15 adhered to the moving handrail 1 can be separated by slightly winding operation by the rotating means 19 while the brake device 18 is operated. Further, when the moving handrail is moved leftward next time, the brake device 1
The cleaning body 15 adhered to the moving handrail 1 can be separated by operating the moving handrail 8. In still another embodiment, when the release unit 11 drives the contact unit 14 downward, the rotating shafts 16 and 17 may also be driven downward to separate the cleaning body 15 adhered to the moving handrail 1. In any case, a separating means for separating the cleaning body 15 from the moving handrail 1 at least until the stopped moving handrail 1 is operated again is sufficient. 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 body 15 at least until the stopped moving handrail 1 is operated again. It may be configured as follows.

Accordingly, when the stopped moving handrail 1 is actuated again, the pressing force of the pressing means 9 on the cleaning body 15 is released at this time. Damage 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 while the unused portion of the cleaning body 15 is sent out from the rotating shaft 16 side, the used portion of the cleaning body 15 is wound on the rotating shaft 17 side to prepare for the next cleaning operation.

Incidentally, the pressing force of the conventional moving handrail cleaning device 3 on the moving handrail 1 is the same regardless of the use environment. The cause of soiling of the moving handrail 1 is due to a passenger's hand marks, cotton dust of a passenger's clothing, and dust, and since the moving handrail 1 rotates while rubbing with the handrail holding member, the friction generates static electricity in the handrail. In some cases, dust or the like floating due to the generated static electricity is attracted to the moving handrail 1 to advance the stain. It is known that the degree of the stain is more severe in the moving handrail 1 of the passenger conveyor having many users. In the case of department stores, supermarkets, etc., the moving handrail 1 of the escalator installed on the first floor is heavily stained, and decreases as it goes upstairs. Therefore, when cleaning the moving handrail 1, it is necessary to change the way of cleaning the moving handrail 1 depending on the usage environment of the passenger conveyor.
Therefore, the moving handrail cleaning device 3 can adjust the pressing force of the cleaning body 15 to be strong in the moving handrail 1 of the passenger conveyor that frequently uses the passenger, and to adjust the pressing force of the cleaning body 15 to be weak in the passenger conveyor with few users. did.

FIG. 3 is a cross-sectional view of a portion of the moving handrail cleaning device 3 used for the moving handrail 1 with less contamination, which pushes up the cleaning body 15. In FIG. 3, 1 is a moving handrail, 15 is a cleaning body,
14 is a contact portion for pushing up the cleaning body, 13 is a spring for transmitting pressure to the cleaning body 15, 12 is a movable member on which the spring 13 is mounted, 2
1 is a bolt for adjusting the pressing force of the spring 13, 20 is a plunger device comprising the pressing means 9 and the releasing means 11, and 22 is the spring 13
L1 is the size of the spring pressing. When the moving handrail 1 is less contaminated, the pressing force is adjusted by the pressing force adjusting bolt 21 of the spring 13 so that the moving handrail 1 has the spring pressing dimension L1. On the other hand, when it is used for the moving handrail 1 of a passenger conveyor with much contamination,
As shown in FIG. 4, when the spring adjusting plate 22 is pushed up by the spring pressing force adjusting bolt 21 so that the pressing dimension L2 of the spring 13 is smaller than the pressing dimension L1 of FIG. Since the pressure is applied, it is possible to easily remove the dirt from the moving handrail 1 that has much dirt.

In the above-described embodiment, the moving handrail cleaning device 3 is configured to release the pressing force of the moving handrail 1 at least when the moving handrail 1 is activated. However, a constant pressing force is always applied to the moving handrail. The present invention can also be applied to a moving handrail cleaning device 3 that is provided via a cleaning body.

[0020]

As described above, the apparatus for cleaning a moving handrail of a passenger conveyor according to the present invention is capable of adjusting the pressing force of a cleaning body for cleaning the moving handrail. Even in this case, since the above-described pressing force can be adjusted and used, a good and stable cleaning effect can always be obtained with basically the same configuration.
