Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 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. 1 which is a block diagram showing an enlarged main part of FIG. ing.

A speed detecting means 6 is provided at the free end of the rotatable lever 5, and the speed at which the lever 5 is urged counterclockwise by a spring 4 provided at the free end of the lever 5 to press the moving handrail 1 is provided. The detection means 6 detects the moving speed of the moving handrail 1. The speed detecting means 6 is connected to an operating means 8 via a signal of a switch 7 which opens and closes in conjunction with a starter switch of the passenger conveyor, and an operation of the pressing means 9 is permitted by an output of the operating means 8. Have been. The speed detecting means 6 is connected to the releasing means 11 via a signal of a switch 10 which opens and closes in conjunction with a start switch of the passenger conveyor. The pressing means 9 and the releasing means 11 are usually constituted as a plunger device or a hydraulic device. A movable member 12 which moves up and down by these means is provided with a contact portion 14 via a spring 13. A cleaning member 15 made of paper or non-woven fabric impregnated with a polishing agent such as silicon is disposed between the contact portion 14 and the moving handrail 1. ing. A brake device 18 is connected to the rotation shaft 16, and the rotation means 1 is connected to the rotation shaft 17.
9 are connected to each other.

Next, the operation of cleaning the moving handrail 1 using 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 operates, when the moving speed reaches 70% of the rated speed,
It is detected by the determination circuit 6a of the speed detection means 6 shown in FIG. At this time, since the switch 7 linked to the start switch is closed, the operating means 8 is operated to press the pressing means 9.
Operation is allowed. Normally, in order to start the cleaning operation by the moving handrail cleaning device 3 in conjunction with the start switch, the pressing means 9 pushes the contact portion 14 upward through the movable member 12 and the spring 13 to raise the cleaning body 15. The moving handrail 1 is pressed against the surface with a predetermined pressing force. Therefore, the polisher 15 is pressed to apply a polishing agent to the surface of the moving handrail 1 and wipe off the oil attached to the surface. As described above, since the cleaning of the moving handrail 1 is performed from the beginning of the operation of the passenger conveyor,
Even if the passenger touches the surface of the moving handrail 1 and the oil adheres, the oil is immediately removed before the oil is fixed on the moving handrail 1 as dirt.

Next, the start switch of the passenger conveyor is set to O
When stopped in the FF state, this also serves as a cleaning work termination command, and the detection circuit 6a detects that the speed of the moving handrail 1 has become 70% or less of the rated value. 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. Accordingly, 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 next time, the pressing force of the cleaning body 15 on the moving handrail 1 is not affected. . As described above, since the moving handrail 1 is always cleaned by the cleaning body 15 while the passenger conveyor is being started, even if the passenger touches the surface of the moving handrail 1 and the oil adheres, the moving handrail is not moved. The moving handrail 1 is immediately removed before it is fixed as a stain on the moving handrail 1, and does not remain attached until the moving handrail 1 operates again.

When the pressing force by the pressing means 9 is released as described above, the cleaning body 15 is separated from the moving handrail 1 downward. May be in contact. 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 around the rotation shaft 17 while a new portion of the cleaning body 15 is sent out from the rotation shaft 16 side, When the cleaning body 15 is sent out, the cleaning body 15 that has come into contact with the moving handrail 1 is separated. In another usage mode, the cleaning body 15 contacting the moving handrail 1 can be separated by slightly winding the rotating shaft 17 by the rotating means 19 while the brake device 18 is operated. Further, when the moving handrail 1 is moved to the left next time, the cleaning device 15 in contact with the moving handrail 1 can be separated by operating the brake device 18.
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 that has contacted 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. Release means 11
Can also serve as the separating means as described above,
The release unit 11 may also be configured to release the pressing force of the cleaning unit 15 by the pressing unit 9 at least before the stopped handrail 1 is operated again.

Thereafter, when the stopped moving handrail 1 is actuated again, at this time, since the pressing force of the cleaning means 15 by the pressing means 9 is released, the cleaning body 15 is actuated by the moving handrail 1 which has started to operate as in the prior art. Damage can be prevented, and stable cleaning can be performed for a long time. At the initial stage of starting the passenger conveyor, preferably when the passenger conveyor is stopped, the brake device 18 is released and the rotating means 19 is rotated clockwise to remove the unused portion of the cleaning body 15 from the rotating shaft 16 while cleaning. The used portion of the body 15 is wound around the rotating shaft 17 to prepare for the next cleaning operation.

In the embodiment described above, the speed detecting means 6
The speed detecting means 6 detects that the moving speed of the moving handrail 1 has reached 70% or more of the rated speed, the operating means 8 allows the operation of the pressing means 9, and the speed is reduced to 70% of the rated speed. The release means 11 is operated when the temperature is lowered, but the present invention is not limited to this. For example, in another embodiment of the present invention, the activation switch of the passenger conveyor is
After a lapse of a predetermined time from the N state, the operating means 8 allows the operation of the pressing means 9, or when the start switch is turned off or after the lapse of the predetermined time, the releasing means 11 causes the pressing means 9 to operate. The pressing may be released.
