Description

The present invention relates to a handrail sterilization apparatus used on a man conveyor.

  In a man conveyor such as an escalator or a moving sidewalk, a moving handrail having an endless shape with a C-shaped cross section is generally used. This moving handrail is intended to be grasped by passengers who get on and off the step or passengers on the step, and is driven to synchronize with the step.

Originally, it is desirable that the passenger always grasps the moving handrail while using the man conveyor. However, since the man conveyor is used by an unspecified number of people, some passengers feel uncomfortable touching the moving handrail.

In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.
In the following, a specific configuration of an escalator used when moving between upper and lower floors will be described as an example of a man conveyor, and description of other examples such as a moving sidewalk will be omitted.

Embodiment 1 FIG.
FIG. 1 is a side view of a main part showing a man conveyor according to Embodiment 1 of the present invention, FIG. 2 is a diagram showing the structure thereof, and FIG. 3 is a structure of a handrail disinfection device for man conveyor according to Embodiment 1 of the present invention. FIG.

  FIG. 1 shows the lower entrance of the escalator. 1 and 2, 1 is a step that passengers get on when moving between the upper and lower floors, 2 is a deck board provided on both sides of step 1, 3 is an inner side of a glass panel or the like supported by the deck board 2 A plate 4 is a moving handrail for a passenger who gets on and off the step 1 or a passenger on the step 1 to grab.

  The moving handrail 4 generally has a C-shaped cross section and is formed in an endless shape. The moving handrail 4 is driven so as to synchronize with step 1, and the upper portion thereof and the inverted portion at the entrance / exit are moved along the edge of the inner plate 3. The lower part of the moving handrail 4 moves in the deck board 2 or a truss (not shown).

  5 is an escalator control panel, 6 is a pole standing at the entrance, 7 is a human sensor provided on the pole 6, 8 is a thermohygrometer provided in the deck board 2, and 9 is the deck board 2 It is a handrail sterilization apparatus provided in the inside.

The control panel 5 controls the entire operation of the escalator, such as step 1 and travel control of the moving handrail 4. The control panel 5 outputs an activation signal when the escalator is activated, a speed signal of Step 1 (moving handrail 4), and the like to the handrail sterilizer 9 as necessary.
The human sensor 7 has a function of detecting the presence of an escalator passenger before the passenger gets on the step 1, for example. When the human sensor 7 detects the presence of a passenger, the human sensor 7 outputs a detection signal to the control panel 5 or the handrail sterilizer 9 as necessary.

  The thermohygrometer 8 has a function of measuring the temperature and humidity around the escalator. In addition, the installation location of the thermohygrometer 8 is not specifically limited, For example, you may install the thermohygrometer 8 in the vicinity of the handrail disinfection apparatus 9, the control panel 5, the pole 6, etc. The thermohygrometer 8 outputs temperature and humidity detection signals to the handrail sterilizer 9 as necessary.

The handrail sterilization apparatus 9 has a function of performing sterilization of the moving handrail 4 using ozone which has high sterilization performance and can be easily used in recent years. The handrail disinfection device 9 is disposed, for example, in the deck board 2 (or truss) in the vicinity of the entrance / exit. In addition, if the entrance / exit on the handrail sterilization apparatus 9 installation side is a escalator entrance, the moving handrail 4 just before a passenger can use can be sterilized. Moreover, if the entrance / exit on the handrail disinfection device 9 installation side is the exit of the escalator, the moving handrail 4 immediately after being used by the passenger can be sterilized.
Below, with reference also to FIG. 3, the structure of the handrail disinfection apparatus 9 is demonstrated concretely.

  The main part of the handrail sterilization apparatus 9 includes a processing apparatus 10, an ozone generator 11, a stirring fan 12, an exhaust pump 13, an ozone decomposition catalyst 14, an ozone detector 15, and an operation control means 16.

  The processing apparatus 10 has, for example, a box shape having a predetermined sealing degree, and a processing chamber for sterilizing the moving handrail 4 with ozone is formed therein. That is, in the handrail sterilization apparatus 9, this processing chamber is filled with ozone, and sterilization is performed through the moving handrail 4 therein. Specifically, in the processing apparatus 10 in the present embodiment, two processing chambers 18 and 19 are formed by the partition plate 17, and the processing chambers 18 and 19 are narrow in the upper portion of the processing apparatus 10. They are connected by a connecting part 20. In addition, the process chambers 18 and 19 are connected only by the connection part 20, and are not connected by the other part.

  Further, the processing apparatus 10 is formed with through holes 21 and 22 for allowing the movable handrail 4 to pass through the processing chamber. The through hole 21 is formed on one side of the processing apparatus 10 and opens into the processing chamber 18. The through hole 22 is formed in the upper part on the other side of the processing apparatus 10 and opens into the processing chamber 19. The through holes 21 and 22 form a straight space with the connecting portion 20, and the moving handrail 4 is provided in the processing apparatus 10 with the through hole 21, the processing chamber 18, the connecting portion 20, the processing chamber 19, and the through hole. It arrange | positions so that the hole 22 may be penetrated sequentially.

  The ozone generator 11 has a function of generating ozone and supplying the generated ozone into the processing chamber of the processing apparatus 10. The ozone generator 11 in the present embodiment supplies the generated ozone into one processing chamber 18. Reference numeral 23 denotes a power source, and reference numeral 24 denotes a controller for the ozone generator 11 to which power is supplied from the power source 23. The ozone generator 11 is controlled by the operation control means 16 via the controller 24.

  The stirring fan 12 is for stirring the ozone supplied from the ozone generator 11 in the processing chamber. For example, the stirring fan 12 is provided in the processing chamber 18 like the ozone generator 11 so that the ozone supplied from the ozone generator 11 into the processing chamber 18 can be sent to the moving handrail 4 side. The ozone generator 11 is disposed on the opposite side of the moving handrail 4. Reference numeral 25 denotes a controller for the agitating fan 12 to which power is supplied from the power source 23. The stirring fan 12 is controlled by the operation control means 16 via the controller 25.

  The exhaust pump 13 is for exhausting the air in the processing chamber of the processing apparatus 10 to the outside. For example, the exhaust pump 13 sucks air in the processing chamber 19 from a pipe 26 connected to the processing chamber 19 and discharges the sucked air to the outside of the processing apparatus 10. Since the air in the processing chamber 19 is discharged to the outside by driving the exhaust pump 13, the inside of the processing chambers 18 and 19 is always kept at a negative pressure while the exhaust pump 13 is driven. It is.

  In the handrail sterilization apparatus 9 having the configuration shown in FIG. 3, when outside air enters the processing chamber from the through holes 21 and 22, most of the air is not ozonized in the ozone generator 11 and processed. It passes through the piping 26 from the chamber 19 and is discharged to the outside. That is, when air enters the processing chamber from the through holes 21 and 22, the ozone concentration in the processing chamber decreases, and the sterilizing effect of the handrail sterilization apparatus 9 decreases.

  In order to prevent such a situation, for example, in a portion close to the stirring fan 12 of the processing apparatus 10 and on the windward side of the stirring fan 12 (in the case shown in FIG. 3, the lower portion of the processing chamber 18). An intake port (not shown) for taking outside air into the processing chamber is formed. That is, air is taken into the processing chamber from this inlet, and air is prevented from entering the processing chamber through the through holes 21 and 22. With such a configuration, the air taken into the processing chamber 18 from the intake port can be supplied to the ozone generator 11 to generate ozone, and the ozone concentration in the processing chamber can be kept high. Become. The intake port may be configured such that the opening area (the amount of air entering the processing chamber from the intake port) can be adjusted according to the suction pressure of the exhaust pump 13.

  The ozone decomposition catalyst 14 is for preventing ozone generated by the ozone generator 11 from being discharged out of the processing chamber as it is. For example, the ozone decomposition catalyst 14 is provided in the middle of a pipe 26 connecting the processing chamber 19 and the exhaust pump 13, and decomposes ozone in the air passing through the pipe 26. That is, the air sucked into the pipe 26 from the processing chamber 19 by the exhaust pump 13 is decomposed in ozone when passing through the ozone decomposition catalyst 14, and then passes through the exhaust pump 13. Discharged outside. As shown in FIG. 3, by disposing the ozone decomposition catalyst 14 in front of the exhaust pump 13, the exhaust pump 13 can be protected from ozone.

  The ozone detector 15 has a function of detecting ozone exceeding a predetermined reference value. The ozone detector 15 is provided to detect ozone leaking from the processing chamber of the processing apparatus 10 and is installed outside the processing chamber. The ozone detector 15 may be one having a function capable of detecting the presence or absence of ozone at a plurality of levels, or one having a function capable of detecting the ozone concentration itself (so-called ozone concentration meter). The ozone detector 15 outputs a detection signal to the operation control means 16 when detecting ozone equal to or higher than a predetermined reference value (that is, ozone leakage from the processing chamber), for example.

  The operation control means 16 has a function of controlling the operation of each component provided in the handrail sterilization apparatus 9. The handrail disinfection device 9 is also provided with a predetermined timer 27, and the operation control means 16 receives an input signal from an external device (for example, the control panel 5, the human sensor 7, etc.), the timer 27, the ozone detection. Each operation of the ozone generator 11, the stirring fan 12, the exhaust pump 13, and the like is appropriately controlled based on an input signal from the container 15.

  Next, the operation of the escalator (particularly, the handrail sterilization apparatus 9) having the above-described configuration will be specifically described with reference to FIG. FIG. 4 is a flowchart showing the operation of the man conveyor in the first embodiment of the present invention.

  When the escalator is activated (S101), step 1 and the moving handrail 4 are driven by the control panel 5. Ozone generation in the handrail disinfection device 9 is stopped when the escalator is activated. Even if an activation signal is input from the control panel 5, the ozone into the processing chamber is not detected until the passenger is detected by the human sensor 7. Is not supplied (No in S102, S103).

  When a passenger is detected by the human sensor 7 after the escalator is activated (Yes in S102), a detection signal is input from the human sensor 7 to the handrail disinfection device 9. The handrail disinfection device 9 receives each detection information from the thermosensor 8 by receiving a detection signal from the human sensor 7 (S104). Then, the handrail sterilization apparatus 9 sets sterilization conditions based on the temperature and humidity information acquired in S104, and generates ozone (S105).

  Specifically, the operation control means 16 drives the ozone generator 11, the agitation fan 12, and the exhaust pump 13, and enters the processing chamber 18 from the ozone generator 11 based on the temperature and humidity measured in S104. Adjust the amount of ozone supplied. At this time, by separately providing an ozone concentration meter in the processing chamber, control may be performed such that the measured concentration by the ozone concentration meter is fed back and the ozone concentration in the processing chamber is kept constant.

  Note that the ozone supplied from the ozone generator 11 into the processing chamber 18 is sprayed on the moving handrail 4 in the processing chamber 18 by the stirring fan 12 and then rides on the air flow generated by the operation of the exhaust pump 13. The ozone decomposition catalyst 14 is reached through the connecting portion 20, the processing chamber 19, and the pipe 26 in this order. The ozone that has reached the ozone decomposition catalyst 14 is decomposed by the ozone decomposition catalyst 14 and discharged to the outside of the processing apparatus 10. Since the exhaust pump 13 is operating while ozone is being supplied from the ozone generator 11, the inside of the processing chambers 18 and 19 is always kept at a negative pressure, and ozone passes through the through holes 21 and 22. It is not discharged to the outside.

  When the supply of ozone is started in S105, the operation control means 16 has detected N passengers during the immediately preceding time T1 based on the time measured by the timer 27 and the detection signal from the human sensor 7. It is determined whether or not (S106). In addition, each value of time T1 and the number N of passengers is memorize | stored in the memory | storage means (not shown) previously.

  When the number of passengers detected during the immediately preceding time T1 is less than N (that is, when there are few escalator passengers), the operation control means 16 sets the ozone concentration in the processing chambers 18 and 19 in S105. Each device is controlled so as to decrease the value from the value to a predetermined value (No in S106, S107). If the ozone concentration in the processing chambers 18 and 19 is decreased in S107, the operation control means 16 next determines whether or not a passenger is detected by the human sensor 7 during the immediately preceding time T1 (S108). . If the detection signal is received from the human sensor 7 during the immediately preceding time T1, the process proceeds to S106, and if the detection signal is not received from the human sensor 7, the process proceeds to S103. That is, according to the above control, when the time T1 has elapsed since the last passenger was detected by the human sensor 7, the operation control means 16 stops the supply of ozone from the ozone generator 11 (No in S108). , S103).

  On the other hand, when the number of passengers detected during the immediately preceding time T1 is N or more (Yes in S106), the operation control means 16 determines whether or not the current ozone concentration is set to the maximum (S109). If not set to the maximum, each device is controlled so that the ozone concentration in the processing chambers 18 and 19 is increased by one step (S110). Thereafter, the operation control means 16 determines the presence or absence of ozone leakage based on the detection signal from the ozone detector 15 (S111), and proceeds to S106 if no ozone leakage has occurred, or proceeds to S103 if it has occurred. The above process is performed.

  According to Embodiment 1 of the present invention, the handrail 4 can be sterilized using ozone which has high sterilization performance and can be easily used in recent years. That is, in the handrail sterilization apparatus 9 having the above-described configuration, when ozone supplied from the ozone generator 11 is sent from the processing chamber 18 to the connecting portion 20 and the processing chamber 19, the ozone is transferred to the surface of the moving handrail 4 ( It can be applied evenly to the entire outer surface / C-shaped inner surface) and can exhibit excellent sterilization effect.

  In the handrail sterilization apparatus 9 having the above-described configuration, ozone supplied from the ozone generator 11 into the processing chamber is discharged to the outside as it is, or ozone is discharged to the outside through the through hole 21 or 22. There is no fear. Furthermore, even if ozone leaks, it can be immediately detected by the ozone detector 15, and appropriate operations such as stopping the supply of ozone can be performed quickly.

  Moreover, in the handrail sterilization apparatus 9 having the above-described configuration, the amount of ozone supplied from the ozone generator 11 into the processing chamber is adjusted based on the number of passengers detected by the human sensor 7 within the predetermined time immediately before. . For this reason, when there are many passengers, increase the ozone concentration to increase the sterilization efficiency, and when there are few passengers, prevent the generation of useless ozone, etc. Is possible.

In the present embodiment, the case where the air taken into the pipe 26 from the processing chamber 19 is passed through the ozone decomposition catalyst 14 and then discharged to the outside has been described. However, since ozone has a deodorizing effect, ozone used for sterilization in the handrail sterilization apparatus 9 may be reused for deodorization in other parts of the escalator.
FIG. 5 is a diagram showing another configuration of the handrail disinfection device for man conveyors according to Embodiment 1 of the present invention, and shows the configuration when the exhaust gas of the handrail disinfection device 9 is reused for deodorization. It is.

  The handrail sterilization apparatus 9 shown in FIG. 5 corresponds to a device obtained by removing the ozone decomposition catalyst 14 from that shown in FIG. That is, in the handrail sterilization apparatus 9 shown in FIG. 5, the air sucked into the pipe 26 from the processing chamber 19 by the operation of the exhaust pump 13 does not decompose ozone contained in the pipe 26 26 is passed. A pipe 26a is further connected to the tip of the exhaust pump 13, and the air containing ozone sucked from the processing chamber 19 passes through the pipe 26a and is in the main frame of the escalator (for example, in the machine room). Alternatively, it is released as it is toward a specific site.

  In escalators, sulfur-containing oil may be used. In such a case, for example, by extending the pipe 26a from the exhaust pump 13 to the oil use site, the air containing ozone is led to the oil use site by the pipe 26a, and ozone (including air) is released toward the use site. To do. Thereby, the smell peculiar to sulfur can be extinguished by ozone, and passengers' discomfort can be alleviated.

Embodiment 2. FIG.
In the present embodiment, with reference to FIGS. 6 to 13, another configuration example of the handrail sterilization apparatus 9 will be specifically described. FIG. 6 is a diagram showing a configuration of a handrail disinfection device for man conveyors in Embodiment 2 of the present invention, and FIGS. 7, 8, and 10 to 13 are handrail disinfection for man conveyors in Embodiment 2 of the present invention. FIG. 9 is a diagram showing another configuration of the apparatus, and FIG. 9 is a diagram showing a configuration of the ozone generator shown in FIG.

  The handrail sterilization apparatus 9 shown in FIG. 6 includes the processing apparatus 10, the ozone generator 11, the circulation pump 28, the ozone decomposition catalysts 29 and 30, the ozone detector 15, and the operation control means 16, and the main parts thereof are configured. .

  In FIG. 6, in the processing apparatus 10, two processing chambers 18 and 19 are connected by a pipe 31 on the opposite side of the connecting portion 20. About the other part of the processing apparatus 10, and the ozone generator 11 and the ozone detector 15, since it has the structure and function similar to Embodiment 1, detailed description is abbreviate | omitted.

  The circulation pump 28 is for circulating the air in the processing chamber. The circulation pump 28 is provided, for example, in a pipe 31 that connects the processing chambers 18 and 19, and is configured so that the air in the processing chamber 19 can be sent to the processing chamber 18 without passing through the connecting portion 20. ing. That is, when the circulation pump 28 is operated, the air in the processing apparatus 10 is circulated so as to return to the processing chamber 18 again through the processing chamber 18, the connecting portion 20, the processing chamber 19, and the piping 31. The circulation pump 28 is shown as an example of a circulation means for circulating the air in the processing apparatus 10. As long as the above function can be provided, other means such as a fan may be adopted as the circulation means.

  The ozone decomposition catalysts 29 and 30 are installed in the vicinity of the through holes 21 and 22 so as to surround the periphery of the moving handrail 4 inside the processing chamber. The functions and installation purposes of the ozone decomposition catalysts 29 and 30 are the same as those of the ozone decomposition catalyst 14. In the handrail sterilization apparatus 9 shown in FIG. 6, since the exhaust pump 13 is not provided, the processing chamber cannot be kept at a negative pressure during ozone supply. For this reason, the air in the processing chamber is discharged to the outside of the processing apparatus 10 through the through holes 21 and 22. The ozone decomposition catalyst 29 has a function of decomposing ozone contained in the air when the air in the processing chamber 18 is discharged to the outside through the through hole 21. The ozone decomposition catalyst 30 has a function of decomposing ozone contained in the air when the air in the processing chamber 19 is discharged to the outside through the through hole 22.

  The operation control means 16 is based on an input signal from an external device (for example, the control panel 5 or the human sensor 7), an input signal from the timer 27, the ozone detector 15, or the like. Each operation of the pump 28 and the like is appropriately controlled, and for example, the processing flow shown in FIG. 4 is performed.

  According to this configuration, the air in the processing chamber can be appropriately circulated by the circulation pump 28, and when the ozone supplied from the ozone generator 11 is sent from the processing chamber 18 to the connecting portion 20 and the processing chamber 19. The ozone can be uniformly applied to the entire surface (outer side surface / C-shaped inner side surface) of the moving handrail 4. For this reason, the sterilization effect which was excellent similarly to the handrail sterilization apparatus 9 shown in FIG. 3 can be exhibited.

  The handrail sterilization apparatus 9 shown in FIG. 7 is provided with a roller 10a in the processing apparatus 10 in addition to the components shown in FIG. As for the configuration other than the roller 10a, the configuration shown in FIG. 5 or 6 may be adopted.

  In the first embodiment, a case has been described in which two through holes 21 and 22 are formed in the processing apparatus 10 and a part of the moving handrail 4 is disposed in the processing chamber through the through hole 21 and 22 through the moving handrail 4. However, since the through holes 21 and 22 are merely holes formed in the wall surface of the processing apparatus 10, when the exhaust pump 13 is driven, the gap between the moving handrail 4 and the processing apparatus 10 (that is, the through holes 21 and 22). Air enters the processing chamber. When air enters the processing chamber from the through holes 21 and 22, as described above, the ozone concentration in the processing chamber decreases and the sterilization effect decreases.

  Therefore, in the handrail sterilization apparatus 9 shown in FIG. 7, a roller 10a is installed at the entrance to the processing chamber, and through holes 21a and 22a for passing the moving handrail 4 through the processing chamber are formed by the roller 10a. . Specifically, the roller 10 a is arranged so as to sandwich the moving handrail 4 from above and below, and is configured to rotate in conjunction with the movement of the moving handrail 4 while keeping the outer peripheral surface in close contact with the moving handrail 4. The roller 10a is made of a material that is in close contact with the moving handrail 4 and does not affect the material of the moving handrail 4, such as rubber.

  If the entirety of the through holes 21a and 22a can be formed by the roller 10a, the gap between the moving handrail 4 and the processing device 10 can be completely closed, and the entry of air from the portion can be completely prevented. However, even if the entire through-holes 21a and 22a cannot be formed, if at least a part of the through-holes 21a and 22a can be formed by the roller 10a, the entry of air from the part can be greatly reduced, The room can be maintained at a high ozone concentration.

  The through holes 21a and 22a may be formed for the first time when the moving handrail 4 enters between the rollers 10a, or open into the processing chamber in the absence of the moving handrail 4. May be.

  In the handrail sterilization apparatus 9 shown in FIG. 8, the moving handrail 4 passes through the inside of the ozone generator 11 in the processing chamber 18. As for other configurations, any of the configurations shown in FIGS. 3 and 5 to 7 may be adopted.

The ozone generator 11 can generate ozone by using a discharge method, an ultraviolet irradiation method, a radiation irradiation method, or the like using oxygen or air as a raw material.
For example, corona discharge, which is a kind of discharge method, is also used in air purifiers and air conditioners. When a high voltage is applied with the needle-shaped electrode placed in the air, an air discharge is generated around the tip of the needle, and when dark, Corona-shaped light is confirmed around the electrode. The corona discharge is an air discharge that appears when a strong radial electric field exists locally, and ozone can be generated by performing such a discharge.

  When this corona discharge is used as the ozone generator 11, the ozone generator 11 generates ozone by discharging between the needle electrode 11a and the plate electrode 11b provided therein. At this time, the moving handrail 4 is disposed in the processing chamber of the processing apparatus 10 so as to pass between the needle electrode 11a and the plate electrode 11b, and the moving handrail 4 is sterilized.

  As a result of experiments conducted by the present applicant, it is possible to disinfect by disposing a target bacterium between the needle electrode 11a and the plate electrode 11b rather than performing sterilization by ozone outside the needle electrode 11a and the plate electrode 11b. It was confirmed that the higher sterilization effect was obtained. For this reason, it becomes possible to exhibit the more excellent disinfection effect by arrange | positioning the moving handrail 4 between the needle electrode 11a and the flat plate electrode 11b.

  The handrail disinfection device 9 shown in FIG. 10 includes a spray device 32 in addition to the components shown in FIG. In addition, about structures other than the spray apparatus 32, any structure shown in FIG. 5 thru | or FIG. 8 may be employ | adopted.

  The spraying device 32 has a function of spraying hydrogen peroxide into the processing chamber of the processing device 10. That is, in the handrail sterilization apparatus 9 shown in FIG. 10, the active species having a higher oxidizing power can be obtained by spraying ozone supplied from the ozone generator 11 onto hydrogen peroxide sprayed from the spray nozzle 33 of the spray apparatus 32. The mobile handrail 4 is sterilized by generating a hydroxy radical consisting of The spray nozzle 33 sprays hydrogen peroxide, for example, toward the moving handrail 4 or toward the ozone supply port of the ozone generator 11 so that the generated hydroxy radicals spread over the entire surface of the moving handrail 4. .

Then, for example, when the ozone is supplied from the ozone generator 11 into the processing chamber in the processing flow shown in FIG. 4, the operation control unit 16 operates the spraying device 32 to spray hydrogen peroxide into the processing chamber. At this time, the operation control means 16 may adjust the spray amount of hydrogen peroxide according to the setting of the ozone concentration. For example, the operation control means 16 appropriately changes the operation of the spraying device 32, such as increasing the spray amount when the ozone concentration setting is high and decreasing the spray amount when the ozone concentration setting is low.
According to this configuration, it is possible to provide the handrail sterilization apparatus 9 having a more excellent sterilization effect.

  A handrail sterilization apparatus 9 shown in FIG. 11 is provided with a coating apparatus 34 instead of the spraying apparatus 32. In addition, about structures other than the coating device 34, any structure shown in FIG. 5 thru | or FIG. 8 may be employ | adopted.

  The coating device 34 has a function of coating hydrogen peroxide on the surface of the moving handrail 4 in the processing chamber of the processing device 10 or in front of the processing chamber. FIG. 11 shows an example in which a coating apparatus 34 is installed outside the processing apparatus 10 and hydrogen peroxide is applied in front of the processing chamber. For example, the coating device 34 brings out the cloth 35 soaked with hydrogen peroxide in accordance with the movement of the moving handrail 4, thereby bringing the cloth 35 into contact with the surface of the moving handrail 4 immediately before entering the processing chamber. Apply hydrogen peroxide.

In the handrail sterilization apparatus 9 shown in FIG. 11, by causing the moving handrail 4 coated with hydrogen peroxide to enter the processing chamber, the hydrogen peroxide on the surface of the moving handrail 4 reacts with ozone in the processing chamber. Hydroxyl radicals are generated and the handrail 4 is sterilized.
Also with this configuration, it is possible to provide the handrail sterilization apparatus 9 having a more excellent sterilization effect.

  The handrail sterilization apparatus 9 shown in FIG. 12 includes a processing apparatus 10, an ozone generator 11, an exhaust pump 13, an ozone decomposition catalyst 14, an ozone detector 15, a brush apparatus 36, and an operation control means 16, and the main parts thereof are configured. Is done.

  In the handrail disinfection device 9, only one processing chamber is formed in the processing device 10, and an ozone generator 11 and a brush device 36 described later are provided in the processing chamber 37. Since only one processing chamber is formed in the processing apparatus 10, both the through holes 21 and 22 open into the processing chamber 37, and the movable handrail 4 is connected to the through hole 21 and the processing inside the processing apparatus 10. It arrange | positions so that the chamber 37 and the through-hole 22 may be penetrated sequentially. A pipe 26 connecting the processing chamber 37 and the exhaust pump 13 also opens into the processing chamber 37, and the ozone decomposition catalyst 14 is provided in the middle of the pipe 26. Since the other parts of the processing apparatus 10 and the ozone generator 11, the exhaust pump 13, the ozone decomposition catalyst 14, the ozone detector 15, and the operation control means 16 have the same configuration and function as in the first embodiment, Detailed description is omitted.

  The brush device 36 is for removing dust adhering to the surface of the moving handrail 4 in the processing chamber 37. The brush device 36 includes, for example, a triple brush 39 connected to the rotor shaft 38, and scrapes off adhering dust by bringing the brush 39 into contact with the surface of the moving handrail 4. In the brush device 36, the rotor shaft 38 is periodically rotated to rest some brushes 39, and the rested brushes 39 are immersed in a cleaning solution to clean the brushes 39 in the processing chamber 37.

  Note that the brush device 36 shown in FIG. 12 is provided with a triple brush 39, but this is merely an example. The brush device 36 may include at least two brushes and have a configuration in which they are periodically moved to scrape off and clean the dust.

  According to this configuration, dust attached to the surface of the moving handrail 4 can be removed by the brush device 36 while sterilizing the entire surface of the moving handrail 4 with ozone. In addition, although the garbage scraped off into the processing chamber 37 by the brush device 36 also includes garbage, this germ is also sterilized by ozone supplied from the ozone generator 11 into the processing chamber 37. Can do. Further, since the brush 39 is periodically cleaned in the processing chamber 37, the brush 39 itself can be kept clean. As shown in FIG. 12, if the pipe 26 is connected to the upper part of the processing chamber 37, there is no possibility that dust that has fallen into the processing chamber 37 enters the pipe 26.

  The handrail sterilization apparatus 9 shown in FIG. 13 includes a processing apparatus 10, an ozone generator 11, an exhaust pump 13, an ozone decomposition catalyst 14, an ozone detector 15, a brush apparatus 40, and operation control means 16, and the main parts thereof are configured. Is done.

In the handrail sterilization apparatus 9, two processing chambers 41 and 42 are formed in the processing apparatus 10, and the processing chambers 41 and 42 are connected vertically via a valve 43.
The upper processing chamber 41 forms a space for the moving handrail 4 to pass through. That is, the through holes 21 and 22 are open to the processing chamber 41, and the moving handrail 4 is disposed in the processing apparatus 10 so as to pass through the through hole 21, the processing chamber 41, and the through hole 22 in order. The processing chamber 41 is connected to the lower processing chamber 42 via a valve 43, and for example, the bottom surface thereof is formed obliquely so that the installation position of the valve 43 is at the lowest position.

  In addition, the processing chamber 41 is provided with a brush device 40 therein. The brush device 40 is for removing dust adhering to the surface of the moving handrail 4 in the processing chamber 41. The dust scraped off from the surface of the moving handrail 4 by the brush device 40 slides on the bottom surface of the processing chamber 41 to reach the valve 43 and further passes through the valve 43 and falls into the lower processing chamber 42.

  The lower processing chamber 42 forms a space for sterilizing bacteria contained in the garbage by ozone. That is, the ozone generator 11 supplies ozone into the processing chamber 42. In addition, the pipe 26 connected to the exhaust pump 13 is connected to the processing apparatus 10 so as to open to the processing chamber 42. Therefore, the processing chamber 42 is kept at a negative pressure while the exhaust pump 13 is driven, and the ozone supplied from the ozone generator 11 into the processing chamber 42 does not enter the processing chamber 41. Then, it is decomposed by the ozone decomposition catalyst 14 through the pipe 26.

  According to this configuration, dust attached to the surface of the moving handrail 4 can be removed by the brush device 40, and bacteria contained in the dust can be sterilized by ozone. Note that ozone supplied from the ozone generator 11 does not enter the processing chamber 41, and ozone does not hit the moving handrail 4. For this reason, the disinfection using ozone is implement | achieved and the moving handrail 4 can be protected from ozone.

  Even if each configuration shown in the present embodiment is adopted as the handrail sterilization apparatus 9, it is possible to sterilize the moving handrail 4 using ozone which has high sterilization performance and has recently become easy to use. it can. Note that matters not described in the present embodiment are the same as those in the first embodiment.

Embodiment 3 FIG.
In the present embodiment, with reference to FIGS. 14 and 15, another operation example of the escalator (particularly, the handrail sterilization apparatus 9) will be specifically described. In addition, about the handrail disinfection apparatus 9, any structure shown in Embodiment 1 and 2 may be employ | adopted.

FIG. 14 is a flowchart showing the operation of the man conveyor in the third embodiment of the present invention.
When the escalator is activated (S201), step 1 and the moving handrail 4 are driven by the control panel 5. Ozone generation is stopped in the handrail disinfection device 9 when the escalator is activated. In the handrail sterilization apparatus 9, when the activation signal is input from the control panel 5, the operation control means 16 determines whether or not a passenger is detected by the human sensor 7 (S202).

  When a passenger is detected by the human sensor 7 and the detection signal is input to the handrail disinfection device 9 (Yes in S202), the operation control means 16 generates ozone from the ozone generator 11, and the processing device 10 The processing chamber is filled with ozone so that the processing chamber has a predetermined normal ozone concentration (S203).

  On the other hand, when the presence sensor is not detected by the human sensor 7 (No in S202), the operation control means 16 generates ozone from the ozone generator 11, and the processing chamber of the processing apparatus 10 is higher than the normal ozone concentration. The processing chamber is filled with ozone so as to obtain a predetermined high ozone concentration (S204). When the processing flow shown in FIG. 4 is performed at the time of passenger detection, for example, the ozone is supplied by setting the high ozone concentration in S204 higher than the ozone concentration recognized as the maximum in S109. And the operation control means 16 will stop supply of the ozone from the ozone generator 11, and will complete | finish a process, if the operation by the said high ozone concentration is performed for a predetermined time (S205).

By performing such control, the ozone concentration in the processing chamber can be increased and reliable sterilization processing can be performed when there are no passengers. If there are no passengers, there is no risk of problems even if the vehicle is operated exceeding the normal ozone concentration.
Note that the processing flow shown in and after S202 in FIG. 14 may be started according to a predetermined schedule or may be started when a predetermined operation command is input.

FIG. 15 is a flowchart showing another operation of the man conveyor in the third embodiment of the present invention.
When the escalator is activated (S301), the speed of the escalator (step 1 / moving handrail 4) is detected in the control panel 5, and the speed signal is input to the handrail sterilizer 9 (S302). In the handrail sterilization apparatus 9, when a speed signal is input from the control panel 5, the operation control means 16 controls the ozone generator 11 and the like based on the speed signal.

  For example, when the escalator is accelerating or traveling at a predetermined constant speed (≠ 0), the operation control means 16 generates ozone from the ozone generator 11 and fills the processing chamber with ozone (Yes in S303). S304). On the other hand, if the escalator is decelerating or stopped, the operation control means 16 stops the supply of ozone from the ozone generator 11 and ends the process (No in S303, S305).

  By performing such control, it is possible to perform an optimum sterilization process in accordance with the speed of the escalator. In addition, in this structure, since supply of ozone is controlled according to the speed of an escalator, it is not necessary to input the detection signal of the human sensor 7 to the handrail sterilization apparatus 9. This configuration is suitable, for example, for an escalator that waits at a low speed or stops when there are no passengers.

  In the above description, the case where the speed of the escalator is detected by the control panel 5 and the detection signal from the control panel 5 is input to the handrail sterilization apparatus 9 has been described. However, this is merely an example, and other configurations may be adopted as means for detecting the speed of the escalator (speed detection means). For example, a roller or the like that rotates in conjunction with the movement of the moving handrail 4 is installed in the processing chamber of the handrail sterilizer 9, and the rotation speed (angle) of this roller is detected by an encoder to acquire the speed of the escalator. good.

Embodiment 4 FIG.
In the present embodiment, with reference to FIGS. 16 to 21, a specific example of the configuration of the escalator including the handrail sterilization apparatus 9 will be described. In addition, about the handrail disinfection apparatus 9, any structure shown in Embodiment 1 and 2 may be employ | adopted.

  FIG. 16 is a side view of the main part showing the configuration of the man conveyor in the fourth embodiment of the present invention. In the escalator shown in FIG. 16, the handrail sterilization apparatus 9 is disposed in the deck board 2 (or truss) of the intermediate inclined portion (section in which the step 1 moves diagonally). When the handrail sterilization device 9 is disposed on the intermediate inclined portion, for example, if the handrail sterilization device 9 is configured to be movable along the moving handrail 4, the handrail sterilization device 9 is moved along with the moving handrail 4. It is also possible to perform sterilization treatment.

  According to this configuration, ozone can be continuously applied to the same position of the moving handrail 4, and an excellent sterilizing effect can be expected even if the ozone concentration in the processing chamber is set low.

FIG. 17 is a side view showing a main part of another structure of the man conveyor according to Embodiment 4 of the present invention, FIG. 18 is a detailed view of the main part of the man conveyor shown in FIG. 17, and FIG. 19 is a block diagram of the man conveyor shown in FIG. It is a block diagram.
The escalator shown in FIGS. 17 to 19 is provided with a marker bacteria application device 44, a marker bacteria determination device 45, and a display device 46 in addition to the handrail sterilization device 9, the human sensor 7, and the like. In addition, the handrail disinfection apparatus 9 may be installed in the intermediate | middle inclination part of the escalator.

  The marker bacteria applying device 44 has a function of attaching a predetermined marker bacteria that can be sterilized by ozone to the surface of the moving handrail 4. For example, the marker bacteria imparting device 44 holds the marker bacteria stained with CTC on a predetermined filter 47, and causes the filter 47 to adhere to the surface of the moving handrail 4. In addition, if marker bacteria are held on the filter 47 in a state where they are covered with a predetermined protective film that allows ozone gas to pass through but cannot pass through the marker bacteria, even after the marker bacteria (filter 47) are attached to the moving handrail 4. , Can prevent scattering of marker bacteria.

  The marker bacterium determination device 45 has a function of determining whether or not the marker bacterium attached to the moving handrail 4 by the marker bacterium application device 44 has been sterilized by the sterilization process of the handrail sterilization device 9. The marker bacteria determination device 45 includes, for example, a light emitting element 48, a light receiving element 49, a determination means 50, a control means 51, and a reporting means 52, and determines the sterilization state of the marker bacteria at a plurality of levels.

  The light emitting element 48 has a function of irradiating predetermined light to the moving handrail 4 (specifically, the filter 47 attached to the moving handrail 4). The marker bacteria inside the filter 47 attached to the moving handrail 4 are colored with bacteria having respiratory activity when irradiated with light from the light emitting element 48. The light receiving element 49 receives the light from the colored marker bacteria and outputs the light reception result to the determination means 50. The determination unit 50 counts, for example, the number of marker bacteria having respiratory activity based on the light reception result of the light receiving element 49 and determines the cleanliness of the moving handrail 4 according to the detected number of bacteria.

  Each operation of the light emitting element 48 and the light receiving element 49 is controlled by the control means 51. The control means 51 also has a function as a display control means for controlling the display of the display device 46, and causes the display device 46 to display the cleanliness of the moving handrail 4 based on the determination result of the determination means 50. .

  For example, the display device 46 is configured to be able to display the cleanliness of the moving handrail 4 at a plurality of levels by colors such as red, yellow, and blue, numerical values, and the like. The control means 51 controls the display content of the display device 46 based on the determination result of the determination means 50, for example, to display according to the cleanliness level determined by the determination means 50. As a result, the passenger of the escalator can confirm whether or not the moving handrail 4 is kept clean by looking at the display on the display device 46, and can grasp the moving handrail 4 with peace of mind.

  The control unit 51 outputs a predetermined signal when the number of bacteria detected by the determination unit 50 is equal to or less than a predetermined value (when a predetermined cleanliness level of the moving handrail 4 is detected), and provides marker bacteria. You may make the apparatus 44 perform collection | recovery operation | movement of the filter 47 on the moving handrail 4. FIG.

  The reporting means 52 has a function of detecting an abnormality of the handrail sterilization apparatus 9 and reporting the abnormality to the outside. When the filter 47 is attached to the surface of the moving handrail 4 from the marker fungus application device 44, the marker fungus in the filter 47 is not subjected to all the sterilization functions of the handrail sterilization device 9 after a certain period of time. Bacteria are sterilized. That is, after the marker bacteria are attached to the moving handrail 4 from the marker bacteria applying device 44, if the completion of the sterilization is not detected by the marker bacteria determination device 45 even after the fixed time has elapsed, the handrail sterilization device 9 Abnormality may have occurred in the sterilization function. For this reason, in this case, the reporting means 52 issues an abnormality to the outside, for example, causes the display device 46 to display a predetermined display, or reports to a monitoring panel, a maintenance company, or the like.

20 is a side view of the main part showing another configuration of the man conveyor according to the fourth embodiment of the present invention, and FIG. 21 is a block diagram of the man conveyor shown in FIG.
The escalator shown in FIGS. 20 and 21 is provided with a marker application device 53, a cleanliness determination device 54, and a display device 46 in addition to the handrail sterilization device 9, the human sensor 7, and the like. In addition, the handrail disinfection apparatus 9 may be installed in the intermediate | middle inclination part of the escalator.

  The marker imparting device 53 has a function of attaching a predetermined marker for detecting bacteria attached to the moving handrail 4 to the moving handrail 4. For example, the marker applying device 53 applies a predetermined marker for CTC staining of bacteria attached to the moving handrail 4 to the surface of the moving handrail 4.

  The cleanliness determination device 54 has a function of determining the sterilization state of the moving handrail 4 based on the marker attached to the surface of the moving handrail 4 by the marker applying device 53. The cleanliness determination device 54 includes, for example, a light emitting element 55, a light receiving element 56, a determination unit 57, a control unit 58, and a reporting unit 59, and determines the sterilization state of the moving handrail 4 at a plurality of levels.

  The light emitting element 55 has a function of irradiating the moving handrail 4 with predetermined light. As for the bacteria on the surface of the moving handrail 4 stained with CTC by the marker applying device 53, those having respiratory activity are colored when irradiated with light from the light emitting element 55. The light receiving element 56 receives the light from the colored bacteria and outputs the light reception result to the determination means 57. For example, the determination unit 57 counts the number of bacteria having respiratory activity based on the light reception result of the light receiving element 56 and determines the cleanliness of the moving handrail 4 according to the detected number of bacteria.

  Each operation of the light emitting element 55 and the light receiving element 56 is controlled by the control means 58. The control means 58 also has a function as display control means for controlling the display of the display device 46, and displays the cleanliness of the moving handrail 4 on the display device 46 based on the determination result of the determination means 57. . When the display device 46 has a configuration capable of displaying the cleanliness of the moving handrail 4 at a plurality of levels, the control unit 58 changes the display of the display device 46 according to the cleanliness level determined by the determination unit 57.

  The reporting means 59 has a function of detecting an abnormality in the handrail sterilization apparatus 9 and reporting the abnormality to the outside. If the bacteria attached to the moving handrail 4 have a normal sterilization function of the handrail sterilization apparatus 9, all the bacteria are sterilized before a certain time elapses after the start of the sterilization process. That is, after the marker is attached to the moving handrail 4 from the marker applying device 53, if the completion of sterilization is not detected by the cleanliness determination device 54 even after the predetermined time has elapsed, the sterilization of the handrail sterilization device 9 An error may have occurred in the function. For this reason, in this case, the reporting means 59 issues an abnormal report to the outside, for example, causes the display device 46 to display a predetermined display, or reports to a monitoring panel or a maintenance company.

  In addition to the marker for CTC staining of bacteria, any substance that reacts with ozone and can be correlated with the sterilization effect can be used as a marker.

  For example, a sample decolorized by ozone, such as indigo, is used as a marker, and a predetermined amount of sample is applied to the surface of the moving handrail 4 from the marker applying device 53. In addition, the amount of the sample applied to the moving handrail 4 is determined based on, for example, the amount at which decolorization is completed with the necessary sterilization CT value (concentration × time). The cleanliness determination device 54 evaluates (determines) the sterilization state of the moving handrail 4 based on the decolorization state of the sample applied to the surface of the moving handrail 4 from the marker applying device 53, and the evaluation result (the moving handrail 4). Cleanliness) is displayed on the display device 46. In addition, the reporting unit 59 issues an abnormal report to the outside if the sample has not been decolored before a certain time has elapsed after the start of the sterilization process.

  The indigo is decolorized by ozone and changes from blue to colorless and transparent. When indigo is used as the marker, the cleanliness determination device 54 can accurately evaluate the decoloring state of the sample by measuring the absorbance at 600 nm, for example.

Embodiment 5 FIG.
In each said embodiment, the case where the apparatus (handrail disinfection apparatus 9) for disinfecting the moving handrail 4 was previously installed in the spot of the escalator was demonstrated. In the present embodiment, a specific description will be given of a portable (portable) device that can be brought into each site by an escalator maintenance staff or the like to perform sterilization processing of the moving handrail 4.

FIG. 22 is a diagram showing a configuration of a handrail disinfection device for man conveyors according to Embodiment 5 of the present invention, and FIG. 23 is a bottom view of the handrail disinfection device for man conveyors shown in FIG.
The handrail sterilization apparatus 60 shown in FIGS. 22 and 23, like the handrail sterilization apparatus 9, has high sterilization performance and sterilizes the moving handrail 4 using ozone that has recently become easy to use. It has a function to do. The main part of the portable handrail sterilization apparatus 60 includes, for example, a processing apparatus 61, an ozone generator 62, a stirring fan 63, a sealing material 64, and operation control means (not shown).

  In the processing device 61, for example, a handle 65 is provided at an upper portion, and a processing chamber 66 opening downward is formed therein. The opening has a rectangular shape slightly narrower than the width of the moving handrail 4, and a sealing material 64 is provided on the entire edge of the processing device 61 that forms the opening.

  The ozone generator 62 and the stirring fan 63 have the same functions as the ozone generator 11 and the stirring fan 12. That is, the ozone generator 62 has a function of supplying ozone into the processing chamber 66, and the stirring fan 63 has a function of stirring the ozone supplied from the ozone generator 62 into the processing chamber 66 in the processing chamber 66. doing. The operations of the ozone generator 62 and the stirring fan 63 are controlled by an operation control unit based on an input signal such as an ON / OFF button.

  When using the handrail sterilization apparatus 60 having the above configuration, an escalator maintenance person lifts the processing apparatus 61 (the entire apparatus) by holding the handle 65, and the opening formed on the lower surface of the processing apparatus 61 is moved by the moving handrail 4. The processing device 61 is placed on the moving handrail 4 so as to be blocked. Then, the maintenance staff presses the processing device 61 against the moving handrail 4 in that state, thereby bringing the sealing material 64 into close contact with the upper surface of the moving handrail 4 and blocking the processing chamber 66 from the outside air in a predetermined sealed state. That is, by filling the inside of the processing chamber 66 with ozone in this state, the surface of the movable handrail 4 facing the processing chamber 66 through the opening can be sterilized.

  Since the moving handrail 4 moves in synchronism with step 1, for example, a roller may be rotatably fixed to the edge of the processing device 61, and a sealing material 64 may be provided on the surface of the roller. With this configuration, when the sealing material 64 provided on the surface of the roller is pressed against the moving handrail 4, the roller rotates in conjunction with the movement of the moving handrail 4, and the processing chamber 66 is kept sealed. Bacteria treatment can be performed.

  FIG. 24 is a diagram showing another configuration of the handrail disinfection device for man conveyors according to Embodiment 5 of the present invention. 24 is provided with a humidifier 67 in the processing chamber 66 in addition to the components shown in FIG.

The humidifier 67 has a function of humidifying the inside of the processing chamber 66. The sterilization effect by ozone increases as humidity increases. For this reason, for example, when the ozone is supplied from the ozone generator 62, the operation control unit also operates the humidifier 67 to humidify the processing chamber 66.
According to this configuration, it is possible to provide the handrail sterilization apparatus 9 having a more excellent sterilization effect.

  FIG. 25 is a view showing another configuration of the handrail disinfection device for man conveyor according to the fifth embodiment of the present invention. A handrail sterilization apparatus 60 shown in FIG. 25 is provided with a germicidal lamp 68 in the processing chamber 66 in addition to the components shown in FIG.

The germicidal lamp 68 has a function of irradiating the processing chamber 66 with light having a predetermined wavelength. The germicidal lamp 68 irradiates light having a wavelength of 254 nm into the processing chamber 66, for example, thereby decomposing ozone supplied from the ozone generator 62 and generating oxygen atoms in the processing chamber 66. (O ₃ ⇒O ₂ + O).
According to this configuration, the moving handrail 4 can be sterilized using oxygen atoms (O) having higher oxidizing power, and an excellent sterilizing effect can be expected.

  FIG. 26 is a diagram showing another configuration of the handrail disinfection device for man conveyors according to the fifth embodiment of the present invention.
