Technical Field
Embodiments of the present invention relate to a handrail belt sterilizing apparatus and a handrail belt sterilizing method of a passenger conveyor.
Background
As a moving mechanism for a person, a passenger conveyor typified by an escalator is used.
In an escalator, endless handrail belts that move in synchronization with steps are provided on both sides of the steps on which a user stands. In order to safely use the escalator, it is desirable that a user rides on the steps in a state that the user grips the handrail belt with hands.
However, in a situation where the handrail belt is not properly sterilized in a period when virus infection is prevalent, there is a possibility that the user is infected.
Conventionally, there have been a method of spraying a disinfectant solution on a handrail and a method of irradiating ultraviolet rays on a handrail to sterilize the handrail.

Detailed Description
Hereinafter, the apparatus and method according to the embodiment will be described with reference to the drawings.
Fig. 1 is an explanatory view showing an overall structure of an escalator of the embodiment.
The escalator 1 has a plurality of steps 4 that circulate between the landing entrance 2 of the lower floor and the landing entrance 3 of the upper floor. Further, a handrail 5 to be held by a user is provided, and the handrail 5 is circularly moved between the entrance 2 and the exit 3 in conjunction with the steps 4.
The handrail belt 5 is supported by handrail plates 6 standing on the left and right across the steps 4, and moves along the handrail plates 6. In the embodiment, the balustrade panel 6 is assumed to be a stainless steel plate, but may be a glass plate.
An infrared user detection sensor 7 is provided near the landing floor F of the landing ports 2 and 3. When the user detection sensor 7 detects a user riding on the escalator 1 from the landing entrance 2, 3, the escalator 1 starts to run, and the steps 4 move.
In the embodiment, the boarding plate F is provided below the entrance 8 that serves as the entrance of the handrail 5, and the first light sources 10 are embedded in the boarding plate F to the left and right across the steps 4. The first light source 10 is flush with the surface of the landing board F, and does not interfere with the landing of a user. In addition, since ultraviolet rays are irradiated in the direction of the handrail 5 under the inlet portion 8, the ultraviolet rays are not irradiated to the user.
The skirt plate portions 9 are provided below the balustrade panels 6 disposed on the left and right, respectively, and are connected to an inlet 8 of a lower floor and an inlet (not shown) of an upper floor, and cover a part of the handrail belt 5 that moves in a circulating manner. Inside the apron portion 9, the second light sources 11 are arranged in parallel to the armrest panel 6 in the left-right direction. The handrail 5 has a front surface and a lip (a folded-back portion 14) on a back surface side which has a portion thereof folded back toward the side of the balustrade panel 6 in a width direction (a left-right direction in fig. 3). The second light source 11 is disposed directly above the folded portion 14 on the back side of the handrail 5, and irradiates the folded portion 14 on the back side of the handrail 5 with ultraviolet light.
Specifically, as shown in fig. 3, the second light source 11 includes an inner (left side in fig. 3) second light source 11a on the side of the step 4 and an outer second light source 11 b. The inner second light source 11a is disposed in the space S inside the handrail support base that supports the handrail 5. Further, a light transmitting hole 13 is provided in a panel attachment plate 12a constituting the handrail support, and light emitted from the second light source 11a on the inner side reaches a folded portion 14 folded back toward the handrail support side on the back side of the handrail 5 through the light transmitting hole 13.
The outer second light source 11b is a light source for irradiating light to the folded portion 14 of the handrail 5 on the side opposite to the inner second light source 11a, and is mounted on the outside of a handrail support base (panel mounting plate 12 b) that supports the handrail 5.
The first light source 10 and the second light sources 11a and 11b are light sources that emit ultraviolet rays, and emit ultraviolet rays having a wavelength of about 222 nm. Ultraviolet rays having a wavelength of about 222nm can sterilize (kill viruses and germs) without causing abnormalities in the human body.
Thereby, the ultraviolet rays emitted from the first light source 10 and the second light sources 11a and 11b are irradiated toward the front surface and the folded part 14 of the handrail 5, whereby the handrail 5 can be sterilized.
The first light source 10 and the second light sources 11a and 11b start irradiation of ultraviolet rays when the user detection sensor 7 provided to start the operation of the escalator 1 detects a user.
Further, the moving distance of the handrail 5 from the entrance portion 8 to the position where the passenger grips the handrail 5 is about 1000mm to 1200mm. In consideration of the walking speed of the user, the time from when the user is detected to when the user grips the handrail 5 is about 2 seconds. When the running speed of the escalator 1 is 30m/min, the second speed is 500mm, and therefore the handrail 5 moves 1000mm in about 2 seconds. If the escalator 1 is operated at 30m/min, the range of the ultraviolet radiation to the handrail 5 can be a value obtained by adding the length of the light source to 500mm when the ultraviolet radiation is radiated from the first light source 10, the second light sources 11a, 11b for 1 second. Based on the calculation result, the irradiation is started when the user detection sensor 7 detects the user, and if the irradiation is performed for 1 second, the user can be sterilized by grasping the handrail 5.
As described above, according to the present embodiment, the ultraviolet rays can be appropriately irradiated toward the position where the user can grasp the handrail 5 when riding on the escalator 1. That is, according to the present embodiment, the ultraviolet rays are not always irradiated to the handrail belt, but are irradiated for a predetermined time from the time when the user detection sensor 7 detects the user. With this configuration, the user can sterilize the position where the user grips the handrail 5, and the handrail can be efficiently sterilized while suppressing deterioration of the handrail.
Next, a handrail belt disinfecting device and a disinfecting method according to an embodiment will be described with reference to fig. 4 and 5.
As shown in fig. 4, the handrail disinfecting device of the present embodiment is composed of an escalator control device 20.
The escalator control device 20 includes a control unit 21, a drive command output unit 22, and a timer 23.
The control section 21 is constituted by a computer which collectively controls the escalator 1. When the user detection sensor 7 detects a user, the drive command output unit 22 outputs a travel command to the drive device 30 to start the travel of the escalator 1. Further, an ultraviolet irradiation command is output to the light source control circuit 40, and ultraviolet rays are irradiated from the first light source 10 and the second light source 11 toward the handrail 5. The timer 23 sets the ultraviolet irradiation time in advance based on the calculation result. In addition, the irradiation time set in the timer 23 can be changed according to the use state of the escalator 1.
In the flowchart of fig. 5, when the user detection sensor 7 detects a user (yes in step S1), the escalator 1 starts to run, and the steps 4 and the handrail 5 circulate between the landing entrance 2 and the landing entrance 3 (step S2).
As the user detection sensor 7 detects the user, the drive command output unit 22 outputs an ultraviolet irradiation command to the light source control circuit 40. Thereby, ultraviolet rays are irradiated from the first light source 10 and the second light source 11 toward the handrail 5 (step S3).
The ultraviolet irradiation is continued for a period of time until the user grips the handrail 5 based on the timing of the timer 23 (step S4). When the time until the user grips the handrail 5 has elapsed based on the time counted by the timer 23, the irradiation of the ultraviolet rays from the first light source 10 and the second light source 11 is stopped (step S5).
When the user is continuously detected by the user detection sensor 7, the ultraviolet irradiation is continued until the user is no longer detected.
< modification example >
It is also possible to indicate "the escalator is disinfected" near the entrance. Can be used safely. "and the like. In this case, when the user is detected by the user detection sensor 7, the user may display a display such as "sterilization completed" or "sterilization in progress" at a place visible to the user. Thereby, the user can hold the handrail 5 with confidence and can use the escalator 1 with confidence.
The first and second light sources 11a and 11b may be configured to constantly emit light by changing the setting of the timer 23 according to the usage status of the escalator 1 in a case of congestion or the like.
In the above embodiment, the escalator 1 is described as an example, but the present invention can be applied to a passenger conveyor such as a moving sidewalk.
Although the embodiments of the present invention have been described above, these embodiments are provided as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
