Description

Handrail adhesive sheet for transport device

The present invention relates to an armrest adhesive sheet for a transport device. More specifically, there is an armrest adhesive sheet for a transport device used as a cleaning double-sided adhesive sheet for a sweeping arm of an armrest and an armrest of a transport device.

The handrails of passenger transport devices, known as escalators or electric walkways, play an important role in the safety of users. Since the user touches, the handrail adheres to dirt or debris, and if the dirt or the like is left untreated, it is unsanitary. Moreover, dirt or debris may also adhere to the guide rollers of the armrests located inside the escalator. Therefore, the armrests are often cleaned to keep them clean.

The armrests, in general, are formed by rubber belts or urethane belts so that the user does not slip when touched. The cleaning method of the handrail is generally a method of wiping the surface dirt using a neutral lotion or liquid silicone, an organic solvent (thinner, toluene). Further, by rubbing the stubborn dirt which is not removed by the wiping, the scraping is performed using an apparatus such as a scraper.

However, in the case where, for example, the newspaper ink adhered to the hand is attached to the handrail, the cleaning with a neutral lotion or liquid polyoxygen or the like cannot be reliably removed. If the ink that cannot be removed is left unattained, sometimes the ink will adhere completely or be immersed in the handrail.

Further, the armrest is endless, and the armrest, after appearing on the upper portion, then enters the floor and passes through the vicinity of the driving device and reappears on the ground through the guide rollers. At this time, the lubricating oil of the driving device or the like may be touched or splashed by the lubricating oil, and the oil may be solidified on the handrail. Alternatively, sometimes the oil attached to the armrest touches the guide roller and solidifies to one of the guide rollers. In this case, it is sometimes insufficient to wipe the oil with a rag or the like. Further, since the cleaning of the guide roller is performed only during the maintenance of the transport device, even if the handrail is wiped with a rag or the like, it may be contaminated immediately.

Most of this stubborn dirt is cleaned by mechanical scraping operations, but the handrails are only temporarily cleaned, and the stubborn dirt will soon adhere again. As a result, it is necessary to perform a troublesome and time-consuming scraping operation on a regular basis, and it takes a lot of labor in the cleaning operation.

Moreover, since the handrail is deformed due to frequent such scraping operations and the appearance is damaged, the handrail must be replaced, resulting in an increase in maintenance costs.

In this regard, a method has been provided in which a double-sided adhesive tape using a synthetic rubber-based adhesive is adhered to the surface of a handrail, and the handrail of the transport device is restarted to clean the guide roller (for example, refer to Patent Document 1 and Patent Literature). two).

However, the double-sided tape of Patent Document 1 and Patent Document 2, after being used, removes the double-sided tape from the armrest, and has left residual glue on the handrail. In addition, when the temperature is removed in summer or after being peeled off for a long time, residual glue may be left.

Further, there has been provided a method of adhering a dirt adsorbing sheet to a surface of a handrail, wherein the dirt adsorbing sheet is formed by immersing a porous film or a spunless nonwoven fabric in a strip shape in a strip-like sheet containing a surfactant and It is formed by washing water of a detergent (for example, refer to Patent Document 3).

However, since the dirt adsorption sheet of Patent Document 3 can adsorb the oil of the inner guide roller even if it adsorbs the oil on the surface of the handrail, it is also impossible to remove the dirt or debris attached to the handrail or the guide roller, or is attached to the handrail. Or the dirt or debris of the guide roller, so sometimes the handrail is immediately contaminated.

After the film of this width and length is adhered to the surface of the handrail, the transport device is activated to rotate the adhesive portion of the film for two to five weeks, and then stopped at a position where the film does not stay inside the transport device. If the transport device is restarted while the diaphragm stays inside the transport device, there is a flaw in the diaphragm which may peel off inside the transport device, which may cause an abnormality in the transport device. After the above steps, the film is peeled off from the surface of the armrest to complete the cleaning. When the impurities are not completely removed in one of the above steps, the above steps are repeated two to three times.
