Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for cleaning guide rollers for moving handrails used in passenger conveyors such as escalators and electric roads.

<Prior art> Generally, the drive mechanism in an escalator is a fourth
It is configured as shown in the figure. That is, the moving handrail 1 is connected in an endless manner, is supported by a moving handrail guide 2, a gate roller 3, and a guide roller 4, and is driven by a drive pulley 5 connected to a drive motor. .

Because of this configuration, if dirt adheres to the moving handrail 1 through the hands of a passenger, this adhered dirt will be transferred to the guide roller 4. Therefore, it is necessary to clean the guide roller 4 by some method. However, although a cleaning machine such as that shown in Japanese Utility Model Application Laid-Open No. 57-135564 has been proposed for cleaning the gate roller 3, no proposal has been made for cleaning the guide roller 4.

<Problems to be Solved by the Invention> Therefore, the general method of cleaning the guide roller 4 is to put one's hand inside the device and scrub the guide roller 4 with a brush or the like, which requires a lot of effort and effort. This requires time and the guide roller 4 cannot be cleaned in areas that cannot be accessed by hand.

Therefore, the present inventor applied an adhesive to at least a part of the other side of the first thin film body, which was attached to the movable handrail 1 by applying an adhesive to one side, and applied an adhesive to one side of the first thin film to attach it to the movable handrail. A cleaning method is provided in which an impregnated part impregnated with a liquid cleaning agent and a cloth-like liquid absorbent are attached to the other surface of the second thin film body attached to the handrail 1, and the guide roller 4 is cleaned while the movable handrail 1 is driven. Proposed. However, a problem arose in that the thin film attached to the moving handrail 1 peeled off. Therefore, we tried using a highly viscous adhesive, but peeling still occurred.

SUMMARY OF THE INVENTION An object of the present invention is to provide a guide roller cleaning method that prevents peeling of the thin film adhered to a moving handrail, reduces time and labor, and can be easily performed.

<Means for solving the problem> Through experiments conducted by the present inventor, the cause of the peeling of the thin film from the moving handrail was determined, and it was found that the peeling was caused by a polishing agent such as silicone oil applied to the surface of the moving handrail. It was confirmed that this occurs.

Accordingly, in order to achieve the above-mentioned object, the present invention includes a step of degreasing and cleaning the surface of the moving handrail;
A step of attaching a first thin film body having a sticky substance on the upper surface to the degreased and cleaned surface of the moving handrail, a step of operating the moving handrail with the first thin film body attached, and a step of removing the first thin film body. A process of attaching an impregnated part for impregnating a cleaning liquid to the front in the moving direction of the moving handrail and a second thin film body having a liquid absorbent behind the impregnated part to the surface of the moving handrail, and after impregnating the impregnated part with the cleaning liquid, removing the moving handrail. The structure includes a step of operating the vehicle.

<Function> In the present invention, after performing the degreasing and cleaning process of the moving handrail as described above, a thin film for cleaning the guide roller is attached to the surface of the moving handrail.
Peeling of the thin film body can be prevented, and the time and labor required for cleaning can be reduced.

<Examples> Examples of the present invention will be described below with reference to the drawings.
FIG. 1 shows a work flow chart showing the cleaning procedure for the guide rollers. First, a degreasing cleaning step 10 is performed on the surface of the handrail in order to remove the polishing agent such as silicone oil applied to the surface of the handrail. At this time, in order not to have a negative effect on the surface of the moving handrail, use ethyl alcohol and 1.1.2-trichloro-
A solution prepared by mixing 1.2.2-trifluoroethane with a volume ratio of 1:1 was applied by hand spray and wiped off with a dry rag.

Next, in the step 11 of attaching the first thin film body, as shown in FIG. Attach it to the handrail 1,
A synthetic rubber adhesive 1 is attached to at least a portion of the upper surface of the first thin film body made of this polyester film 15.
Apply 7. Since the polyester film 15 was attached to the moving handrail surface after it had been degreased and cleaned, it did not peel off like in the past.

In the third step 12, the polyester film 15
In this example, the handrail 1 was operated with the handrail attached to it, and in this example, the handrail 1 was operated two times. As a result, the escalator drive mechanism can be used as is to remove dirt adhering to the guide rollers, so the structure of the cleaning tool is simple.

In the next fourth step 13, after removing the first thin film body described above, a film with a thickness of 0.3 as shown in FIG.
A polyester film 18 with a width of 80 mm and a length of 2400 mm is attached to the moving handrail 1 using a synthetic rubber adhesive 19 coated on the lower surface. An impregnation section 2 made of a urethane sponge with a thickness of 5 mm is impregnated with a liquid cleaning agent on the upper surface of the polyester film 18.
0 and a towel-shaped liquid absorbent 21 are adhered to form a second thin film body. The impregnated portion 20 of the second thin film body contains about 30 c.c. of a cleaning liquid containing water as the main solvent, a small amount of ethyl alcohol, and sodium alkylbenzenesulfonate as main components. Impregnated part 20 at the beginning of the moving handrail 1 in the driving direction
Then, this second thin film body is attached to the moving handrail 1 so that the liquid absorbent 21 is located.

Next, in the fifth step 14, the movable handrail 1 was operated, and in this example, it was operated two times. Through this process, the cleaning liquid in the impregnated portion 20 is applied to the guide roller, and then wiped off by the liquid absorbent 21 to clean the guide roller. The liquid absorbent 21 cannot completely wipe off the cleaning liquid applied to the guide roller. Therefore, after this step 14, step 1
If steps 1 and 12 are carried out, the effect of the sticky substance 17 on the first thin film body will be lost due to the cleaning liquid adhering to the guide roller, so steps 13 and 14 should be carried out after steps 11 and 12. ing.

The above series of tasks can be completed in about 10 to 15 minutes.
This short and simple operation made it possible to almost completely remove dirt from the guide rollers.

<Effects of the Invention> As explained above, in the present invention, after the moving handrail is degreased and cleaned, the thin film for cleaning the guide roller is attached to the surface of the moving handrail, so that peeling of the thin film can be prevented. In addition, by applying a first thin film body having a sticky substance on its surface, and then a second thin film body having a surface impregnated with a cleaning liquid and liquid absorbing to the guide roller, each effect can be fully exerted. to remove dirt from the guide roller.
