FIG. 2 is a schematic diagram of an escalator equipped with a sterilization system according to this embodiment.

This structure enables the film 70 sterilized by the disinfecting device 72 to be provided in accordance with the movement of the handrail belt 38 . Here, it is assumed that the escalator 10 is performing an ascending operation in which the steps 30 and the handrail belt 38 move from the lower floor to the upper floor. The disinfecting device 72 is provided on the lower floor side before the user gets on, and supplies the film 70 after disinfection. The film 70 is attached to the upper surface of the handrail belt 38, that is, the side held by the passenger, and moves together with the handrail belt 38 to the upper floor. After that, it enters the truss 12 together with the handrail belt 38 from the inlet portion 46 , moves in accordance with the operation of the train, and emerges from the inlet portion 48 . The film 70 goes around with the handrail belt 38 and back up to the disinfector 72 .

The film 70 has a length that allows it to be attached to and wound from the handrail belt 38, and has a ring shape longer than the handrail belt 38. - 特許庁Also, the film 70 has a multi-layered structure consisting of a layer that contacts the handrail belt 38 and a layer that can be gripped by passengers. In the embodiment, among users, a user who has boarded the steps 30 is referred to as a passenger. FIG. 3 shows a perspective view in which the structure of the film is simplified. The film 70 is a layer that adheres to and comes into contact with the handrail belt 38, and has a removable adhesive surface (hereinafter referred to as an adsorption material 70a) and an antibacterial function. It is constructed integrally with an absorbent surface (hereinafter referred to as an absorbent material 70b) which is a layer on which it is located.

The adsorption material 70a can be attached to the handrail belt 38 with an adhesive, and is desirably made of a material such as a waterproof material that does not easily leak a liquid such as a disinfectant.

The absorbent material 70b is provided on the upper surface of the adsorption material 70a so as to be grippable by the passenger. The absorbent material 70b is a material capable of containing at least a liquid, such as a polymer sheet of a high-molecular-weight absorbent, pulp using cellulose, etc., and is coated with an antiseptic solution each time the film 70 is rotated. Materials with antibacterial properties or materials that are not severely degraded or damaged by the application of a disinfectant solution are suitable. The absorbent material 70b is desirably made of a material that can absorb the disinfectant and retain water so that passengers can feel that it has been disinfected when they touch it. As a result, passengers can dare to touch the disinfectant by using the film impregnated with the disinfectant, and it is expected that the use of the escalator 10 that grips the handrail belt 38 will be promoted. In this case, it is desirable to absorb an amount of disinfectant that evaporates while the passenger moves from the lower floor to the upper floor or while making a full circle with the handrail belt 38 . An additional disinfectant solution is applied for each lap, so it is always hygienic when it emerges.

In this way, the structure of the film 70 prevents the disinfectant contained in the absorbent material 70b on the top surface from penetrating to the lower surface side than the adsorption material 70a, which is less likely to leak, and prevents the liquid from remaining on the upper surface side. It is possible. By preventing the disinfectant from reaching the handrail belt 38, deterioration of the handrail belt 38 is effectively suppressed.

The thickness of the film 70 in which the two layers of the adsorption material 70a and the absorption material 70b are integrated is approximately 0.1 mm, and is, for example, a water retention tape. Further, for example, if the thickness is up to about 0.8 mm, the operation of the handrail belt 38 within the truss is not affected, and the operation is not affected. The absorbent material 70b may be a combination of an apertured film and an absorbent such as an absorbent polymer. Further, even if the respective layers of the adsorption material 70a and the absorption material 70b are not peelable, they are not limited to the above-described shapes as long as they have the role of an adhesive surface and a sterilized surface.

FIG. 4 is an enlarged view of the lower floor side of the escalator 10 showing the structure of the sterilization system and its surroundings. The sterilization system is composed of a disinfecting device 72 , a sticking device 74 and a winding device 76 .

The disinfecting device 72 includes a driven roller 78 interlocked with the movement of the handrail belt 38, a pressing spring 80 that suppresses the occurrence of slackness in the film 70, a driven roller 82 interlocked with the driven roller 78, and a conductor for directing the conductor of the film 70. A roller 84, a wire roller 86 for directing the wire after peeling off the film 70 from the circling handrail belt 38, an adhesive 88 for preventing the adhesive strength of the adhesive surface from decreasing during each rotation, and disinfection applied to the absorbent material 70b for each rotation. and the liquid 90 .

The sticking device 74 is a device for sticking the film 70 coated with the disinfectant to the handrail belt 38 . FIG. 5 shows a side view (a) and a front view (b) of the structure of the sticking device 74 shown in FIG. The film 70 drawn out from the disinfecting device 72 overlaps the handrail belt 38 by the pointing mechanism 74a for pointing the conductor wire, and is stuck by the crimping mechanism 74b. The crimping mechanism 74b is a roller for pressing, and is provided on the flat portion of the handrail and the rounded curved portion, respectively, so that the handrail belt 38 can be crimped so as not to come off during operation.

The take-up device 76 is a device for peeling off the film 70 that has been wound together with the handrail belt 38 from the handrail belt 38 . FIG. 6 shows a side view (a) and a front view (b) of the configuration of the winding device 76 in FIG. The film 70 that has moved inside the truss 12 together with the handrail belt 38 is peeled off from the handrail belt 38 and recovered by a peeling mechanism 76a. The peeling mechanism 76a is a spatula for peeling the film 70, and is provided on the flat portion and the rounded curved portion of the handrail like the crimping mechanism 74b. The stripped film 70 continues to the next operation of the disinfection device 72. FIG.

It should be noted that the adsorption material 70a and the absorption material 70b operate together while the film 70 is attached to the handrail belt 38 and after it is peeled off by the winding device 76.例文帳に追加

The adhesive 88 and the disinfecting liquid 90 in the disinfecting device 72 are positioned so as to sandwich the collected film 70 from the upper and lower surfaces. At this time, the antiseptic solution 90 may be provided with a reservoir or the like and applied to the surface, or may be sprayed. It should be noted that the film 70 that has been peeled off and collected from the handrail belt 38 will be reused and repeatedly attached to the handrail belt 38 .

In this way, by using a mechanism capable of sterilizing the film 70 each time the handrail belt 38 rotates, deterioration of the handrail belt 38 is effectively suppressed, and the sterilized film 70 can be held by passengers. Become. When using a water-retaining material, the disinfectant absorbed by the film 70 can be touched, so passengers can recognize that it has been disinfected, and it is possible to promote the grip of the handrail belt 38 when using it. be.

Furthermore, while the escalator 10 is running, the sterilization system is in operation in conjunction with the driven roller 78. At this time, the 'disinfection in progress' or 'disinfection in progress' is visible to the passengers. It may be displayed to that effect. The display mechanism here is provided, for example, on the outside of the disinfection device 72 that constitutes the sterilization system, near the boarding plate 34 on the boarding side, on the step 30, etc., but some other display device such as a liquid crystal may be provided. I don't mind. This can provide a sense of security to passengers who are hesitant to hold the handrail belt 38 , and can be a factor in recommending safe usage of the escalator 10 .

In the film 70, a display surface layer is provided as another layer between the adsorption material 70a and the absorption material 70b, and information to be provided to the user is displayed on the display surface. The information to be provided is, for example, a display that calls attention to the fact that it is being disinfected, a display that promotes safe use such as "Let's hold the handrail", and a promotional advertisement such as a wrapping advertisement that is appealing. content to have. The form of information is not limited to characters, and may be figures, illustrations, or the like.

That is, the multi-layered structure of the film 70 is not limited to two layers, but can be three or more layers while considering the thickness. This allows a visual approach to passengers. It is assumed that the absorbing material 70b is a material such as transparent having a property that characters and illustrations on the opposite surface can be transmitted. In this way, it is possible to visually present the display contents on the display surface to passengers.

Alternatively, the disinfectant liquid 90 may be sprayed with a sprayer, and a sensor linked with the disinfectant device 72 may be used to spray the disinfectant liquid upon detection of the approach or boarding of the user. As a result, there is an advantage that the amount of the disinfectant that is always applied to each cycle can be saved during off-peak hours.

Although the sterilization system of the present embodiment has been described for the case where the escalator 10 is in ascending operation, it can also be applied in case of descending operation. In this case, disinfection equipment and other equipment necessary for the sterilization system will be installed on the upper floors. This makes it possible to disinfect the handrail just before the passenger uses it, and to provide the film 70 before the antiseptic solution evaporates.

In addition, in this embodiment, the disinfection device related to the disinfection system is provided externally at a position visible to the user as shown in FIGS. For example, it is not limited to this, and may be provided inside a part of the escalator 10, for example, inside the truss 12 or inside the machine room 16. When the sterilization system is provided externally, it becomes easy to install after installation, and since a large amount of work is not required when additionally installing after installing the main body of the escalator 10, it is possible to obtain installability in renewal or the like. On the other hand, if it is provided inside the escalator 10, the installation location can be arranged so as not to be seen. In this way, it is possible to determine the mounting position according to the situation and apply the sterilization system while ensuring the usability of the conventional escalator 10 .

In this embodiment, a system for sterilizing the handrail belt 38 of the escalator 10 that is conveyed between the upper and lower floors has been described as an example. It may be applied to other passenger conveyors such as sidewalks (auto-road).

As described above, according to the embodiment, a sterilization system including a mechanism for applying a disinfectant solution to the film 70 and a mechanism for attaching the film 70 to the handrail belt 38 is provided, and the handrail belt 38 is constantly disinfected. It is possible to provide a state in which germs and the like are effectively suppressed from sticking to the hands when the handrail belt 38 is gripped by attaching the film 70 thus formed. The sterilized film 70 is attached to the handrail belt 38, goes around with the handrail belt 38, is taken into the sterilization system again, and is sterilized again. By using a material that prevents leakage of the film 70, the antiseptic solution can be prevented from coming into direct contact with the handrail belt 38, and deterioration can be reduced. It can be said that the film 70 is easier to maintain and inspect than the handrail belt 38 and is easy to replace. By utilizing the sterilization system in this way, it is possible to effectively suppress deterioration of the handrail belt 38 and provide passengers with a sterilized surface.
