[0010] Embodiment 1 The configuration of the passenger conveyor 1 according to the first embodiment will be described. Fig. 1 is a diagram showing the configuration of the passenger conveyor 1 according to the first embodiment. In Fig. 1, the passenger conveyor 1 is installed across a lower floor 2a and an upper floor 2b of a building. Furthermore, the passenger conveyor 1 is formed, from the lower floor 2a to the upper floor 2b, with a lower floor normal section 200, a lower floor straight section 201, a lower floor curved section 202, a straight section 203, an upper floor curved section 204, an upper floor straight section 205, and an upper floor normal section 206.

[0011] 1, passenger conveyor 1 comprises truss 3, a plurality of steps 4 supported by truss 3 and connected endlessly, a pair of balustrades 5 mounted on truss 3 and on both sides of the width of the steps 4 along the direction of movement, a movable handrail 6 mounted on the top of the pair of balustrades 5 and moving in sync with the steps 4, skirt guards 7 mounted on the bottom of the pair of balustrades 5, inlets 8 mounted on both ends of skirt guard 7 for retracting the movable handrail 6, a drive unit 9 (not shown) for supplying power to rotate the movable handrail 6 around the balustrade 5, boarding and alighting plates 100a, 100b mounted on lower floor 2a and upper floor 2b for passengers to board and alight on passenger conveyor 1, and chemical sprayers 10a, 10b. In this embodiment, the movement direction of the steps 4 of passenger conveyor 1 is assumed to be direction A, from lower floor 2a to upper floor 2b.

[0012] The configuration of the chemical liquid sprayer 10a will be described. FIG. 2 is a diagram showing the configuration of the chemical liquid sprayer 10a according to the first embodiment. As shown in FIG. 2, the chemical liquid sprayer 10a includes a first detection unit 30a, a chemical liquid sprayer main body 21a, and a chemical liquid spray control device 40a. The chemical liquid sprayer 10b has the same configuration as the chemical liquid sprayer 10a. That is, the chemical liquid sprayer 10b may be configured to include the first detection unit 30b shown in FIG. 1, the chemical liquid sprayer main body 21b shown in FIG. 1, and a chemical liquid spray control device (not shown) equivalent to the chemical liquid spray control device 40a shown in FIG. 2. Hereinafter, a description of the chemical liquid sprayer 10b will be omitted.

[0013] First, the first detector 30a will be described. The first detector 30a is, for example, a non-contact reflective photoelectric sensor. For example, as shown in FIG. 1, one first detector 30a is provided on the boarding / alighting board 100a. The first detector 30a detects passengers who are about to board the passenger conveyor 1.

[0014] Next, the chemical sprayer main body 21a will be described. The chemical sprayer main body 21a is provided in a section that constitutes the entrance in the moving direction of the multiple steps of the passenger conveyor. Furthermore, the chemical sprayer main body 21a is fixed to the balustrade 5, which is provided on the right side when looking from the lower floor 2a to the upper floor 2b. The chemical sprayer main body 21a is fixed to the balustrade 5 in a section that constitutes the entrance to the passenger conveyor 1. Here, the section that constitutes the entrance to the passenger conveyor 1 refers to a section in the mantle section or horizontal section of the floor where the entrance is provided, and in FIG. 1, it refers to a section in the lower floor mantle section 200 or the lower floor water straight section 201. Note that, in order for passengers to hold onto the moving handrail 6 and move safely, it is desirable to fix the chemical sprayer main body 21a to the position of the balustrade 5 in the mantle section, which is a section closer to the entrance, so that the passengers can move safely.

[0015] Fig. 3 is a diagram showing the configuration of the liquid sprayer body 21a according to embodiment 1. As shown in Fig. 3, the liquid sprayer body 21a includes a housing 12, a tank 13, a spray unit 14, and a second detection unit 31a.

[0016] The housing 12 has a tank mounting portion 12a and a balustrade fixing portion 12b. The tank mounting portion 12a is, for example, a container covered with metal and houses the tank 13 therein. A first spray nozzle 15a is provided on the underside of the tank mounting portion 12a, and a second spray nozzle 15b is provided on the upper surface of the tank mounting portion 12a. The first spray nozzle 15a and the second spray nozzle 15b are connected to the spray unit 14. The first spray nozzle 15a corresponds to the first detection unit 30a and is provided for the purpose of spraying the medicinal liquid onto the moving handrail 6. The second spray nozzle 15b corresponds to the second detection unit 31a (described later) and is provided for the purpose of spraying the medicinal liquid onto the passenger's hand 11. The balustrade fixing portion 12b is, for example, made of metal and is provided to extend below the tank mounting portion 12a. The balustrade fixing portion 12b is used to fix the housing 12 to the balustrade 5.

[0017] Tank 13 contains a chemical liquid therein. Tank 13 can contain a chemical liquid having at least one of a sterilizing action, a bactericidal action, and a disinfecting action. Tank 13 also contains, for example, a spray unit 14 therein.

[0018] Here, the term "sterilization action" refers to the action of removing bacteria or viruses to reduce their numbers. The means for removing bacteria or viruses is not limited, and refers to the removal of bacteria or viruses by, for example, killing or washing them away. The term "sterilization action" refers to the action of killing bacteria or viruses to reduce their numbers. The term "disinfection action" refers to the action of removing or killing bacteria or viruses to reduce their numbers to a level that is not harmful to the human body.

[0019] The chemicals used must be safe and hypoallergenic enough to not cause any harm to passengers' faces or eyes, including diluted versions of the chemicals.

[0020] The spray unit 14 includes a spray pump 14a and a pipe 14b. The spray pump 14a sprays the chemical liquid supplied from the tank 13. The spray pump 14a is preferably provided at the bottom of the tank 13 so that the chemical liquid can be supplied even when the amount of chemical liquid in the tank 13 becomes small. The pipes 14b extend vertically from the spray pump 14a and supply the chemical liquid sprayed from the spray pump 14a to the first spray nozzle 15a and the second spray nozzle 15b. The amount of chemical liquid sprayed by the spray pump 14a at one time is set for the first spray nozzle 15a to an amount sufficient to sufficiently sterilize, disinfect, and sterilize the moving handrail 6 in the area where a passenger is likely to grasp it, and for the second spray nozzle 15b to an amount sufficient to sufficiently sterilize, disinfect, and sterilize the hands 11 of passengers. The spray pump 14a can adjust not only the amount of chemical liquid sprayed but also the spray duration and spray timing.

[0021] The second detection unit 31a is, for example, a non-contact reflective photoelectric sensor. The second detection unit 31a is provided on the upper surface of the tank mounting portion 12a, as shown in Fig. 3. The second detection unit 31a detects the hand 11 of a passenger who is about to board the passenger conveyor.

[0022] Next, the chemical solution spray control device 40a will be described. The chemical solution spray control device 40a includes a first determination unit 41, a second determination unit 42, a walking speed calculation unit 43, a moving handrail spray time acquisition unit 44, a memory unit 45, and a chemical solution spray control unit 46. The configuration that realizes the functions of the chemical solution spray control device 40a may be located within the chemical solution spray device main body 21a, or may be located near or far from the chemical solution spray device main body 21a.

[0023] The first determination unit 41 determines whether the first detection unit 30a has detected a passenger attempting to board the passenger conveyor 1. The first determination unit 41 may be configured to make a determination periodically. When the first detection unit 30a detects a passenger, the first determination unit 41 outputs a signal indicating that the passenger has been detected to the walking speed calculation unit 43 and the medicinal solution spray control unit 46.

[0024] The second determination unit 42 determines whether the second detection unit 31a has detected the hand 11 of a passenger attempting to get on the passenger conveyor 1. The second determination unit 42 may be configured to make the determination periodically. When the second detection unit 31a has detected the hand 11 of the passenger, the second determination unit 42 outputs a signal indicating that the hand 11 of the passenger has been detected to the walking speed calculation unit 43.

[0025] The walking speed calculation unit 43 calculates the walking speed of the passenger based on the information detected by the first detection unit 30a and the second detection unit 31a. Specifically, the walking speed of the passenger is calculated from the difference in detection time between the signal indicating that the first detection unit 30a has detected the passenger and the signal indicating that the second detection unit 31a has detected the passenger's hand 11, and the distance between the first detection unit 30a and the second detection unit 31a, and is output to the moving handrail spray time acquisition unit 44. Note that the calculation of the walking speed of the passenger based on the information detected by the first detection unit 30a and the second detection unit 31a is not limited to a mathematically rigorous calculation.

[0026] FIG. 4 is a diagram showing a table stored in the storage unit 45 according to the first embodiment. As shown in FIG. 4, the storage unit 45 stores a table indicating the waiting time before starting to spray the medicinal liquid onto the moving handrail 6, corresponding to the walking speed of the passenger. Here, the waiting time before starting to spray the medicinal liquid onto the moving handrail 6 refers to the waiting time before starting to spray the medicinal liquid onto the moving handrail 6, which allows the medicinal liquid to be sprayed over an area of ​​the moving handrail 6 that is estimated to be grabbed by the passenger based on the passenger's walking speed. For example, as shown in FIG. 4, if the passenger's walking speed is 60 m / min, starting to spray the medicinal liquid onto the moving handrail 6 0.5 seconds after the first detection unit 30a detects the passenger makes it possible to spray the medicinal liquid over an area of ​​the moving handrail 6 that is estimated to be grabbed by the passenger.

[0027] The moving handrail spray time acquisition unit 44 acquires the time to start spraying the medicinal solution onto the moving handrail 6, which corresponds to the walking speed calculated by the walking speed calculation unit 43, from the table stored in the memory unit 45, and outputs this to the medicinal solution spray control unit 46.

[0028] The liquid spray control unit 46 controls the operation of the liquid sprayer main body 21a to spray the liquid medicine. When the first detection unit 30a detects a passenger, the liquid spray control unit 46 puts the liquid sprayer main body 21a into a standby state in which it is ready to operate. When the liquid spray control unit 46 receives a signal indicating the standby time before starting to spray the liquid medicine onto the moving handrail 6, the liquid spray control unit 46 activates the liquid medicine sprayer main body 21a to spray the liquid medicine onto the moving handrail 6 from the first spray nozzle 15 after the elapse of the time from when the first detection unit 30a detected the passenger. When the second detection unit 31a detects the hand 11 of a passenger, the liquid spray control unit 46 activates the liquid medicine sprayer main body 21a to spray the liquid medicine onto the hand 11 of the passenger from the second spray nozzle 15b.

[0029] Here, we will explain the hardware configuration of the chemical liquid spray control device 40a according to embodiment 1. Figure 5 is a diagram showing the hardware configuration of the chemical liquid spray control device 40a according to embodiment 1. The chemical liquid spray control device 40a is realized by a computer such as a personal computer or a microcontroller.

[0030] The chemical solution spray control device 40a includes a processor 1001, a memory 1002, an interface 1003, and a secondary storage device 1004, which are connected to each other via a bus 1000.

[0031] The processor 1001 is, for example, a CPU (Central Processing Unit). The processor 1001 reads an operating program stored in the secondary storage device 1004 into the memory 1002 and executes it, thereby realizing each function of the chemical liquid spray control device 1000.

[0032] The memory 1002 is a main storage device configured, for example, by a RAM (Random Access Memory). The memory 1002 stores programs that the processor 1001 reads from the secondary storage device 1004. The memory 1002 also functions as a work memory when the processor 1001 executes the programs.

[0033] The interface 1003 is an I / O (Input / Output) interface such as a serial port, a USB (Universal Serial Bus) port, a network interface, etc. The interface 1003 performs output from the first detection unit 30a and the second detection unit 31a, and input and output to and from the liquid spray device main body 21a.

[0034] The secondary storage device 1004 is, for example, a flash memory, a hard disk drive (HDD), or a solid state drive (SSD). The secondary storage device 1004 stores various information necessary for the operation of the chemical solution spray control device 40a and programs executed by the processor 1001.

[0035] Next, an operation of the chemical liquid spraying device 10a of the passenger conveyor 1 according to embodiment 1 will be described. Fig. 6 is a flowchart showing the operation of the chemical liquid spraying device 10a of the passenger conveyor 1 according to embodiment 1. The operation of the chemical liquid spraying device 10b has the same configuration as the operation of the chemical liquid spraying device 10a.

[0036] First, the first determination unit 41 periodically determines whether the first detection unit 30a has detected a passenger attempting to board the passenger conveyor 1 (S1). If the first detection unit 30a has detected a passenger (YES in S1), the liquid spray control unit 46 places the liquid spray device main body 21a in a standby state in which it is operable (S2). If the first detection unit 30a has not detected a passenger (NO in S1), the first determination unit 41 again determines whether the first detection unit 30a has detected a passenger attempting to board the passenger conveyor 1.

[0037] Next, the second determination unit 42 periodically determines whether the second detection unit 31a has detected the hand 11 of a passenger attempting to board the passenger conveyor 1 (S3). If the second detection unit 31a has detected the passenger's hand 11 (YES in S3), the liquid medicine spray control unit 46 activates the liquid medicine sprayer main body 21a to spray the liquid medicine onto the passenger's hand 11 from the second spray nozzle 15b (S4). The walking speed calculation unit 43 calculates the passenger's walking speed based on the information detected by the first detection unit 30a and the second detection unit 31a. Specifically, the walking speed of the passenger is calculated from the difference in detection time between the signal indicating that the first detection unit 30a has detected the passenger and the signal indicating that the second detection unit 31a has detected the passenger's hand 11, and the distance between the first detection unit 30a and the second detection unit 31a (S5). Furthermore, if the second detection unit 31a does not detect the passenger's hand 11 (YES in S3), the second determination unit 42 again determines whether the second detection unit 31a has detected the passenger's hand 11 or not.

[0038] Next, moving handrail spray time acquisition unit 44 acquires from memory unit 45 the time to wait before starting to spray the medicinal liquid onto the moving handrail 6, which corresponds to the walking speed of the passenger calculated by walking speed calculation unit 43 (S6). The medicinal liquid spray control unit 46 receives a signal indicating the time to wait before starting to spray the medicinal liquid onto the moving handrail 6, and when that time has elapsed from the time when first detection unit 30a detected the passenger, it activates medicinal liquid spray device main body 21a to spray the medicinal liquid onto the moving handrail 6 from first spray nozzle 15a (S7).

[0039] As described above, the chemical liquid spraying device 10a for the passenger conveyor 1 according to the first embodiment is provided with: a chemical liquid spraying device main body 21a that is provided in a section that constitutes the entrance in the direction of movement of the multiple steps 4 of the passenger conveyor 1, and that sprays a chemical liquid having at least one of sterilizing, bactericidal, and disinfecting effects from a first spray nozzle onto the moving handrail 6; a first detection unit 30a and a second detection unit 31a that detect passengers attempting to board the passenger conveyor 1; a walking speed calculation unit 43 that calculates the walking speed of the passenger based on information detected by the first detection unit 30a and the second detection unit 31a; and a chemical liquid spray control unit 46 that activates the chemical liquid spraying device main body 21a and sprays the chemical liquid based on the walking speed calculated by the walking speed calculation unit 43. This makes it possible to spray the chemical liquid over an area of ​​the moving handrail 6 that is expected to be grasped by passengers, allowing passengers to use the moving handrail with peace of mind.

[0040] Furthermore, the chemical solution spraying device 10a of the passenger conveyor 1 according to embodiment 1 is provided with a memory unit 45 that stores the time to wait before starting to spray the chemical solution onto the moving handrail 6, which corresponds to the walking speed of the passenger, and a moving handrail spray time acquisition unit 44 that acquires from the memory unit 45 the time to wait before starting to spray the chemical solution onto the moving handrail 6, which corresponds to the walking speed calculated by the walking speed calculation unit 43. When the time acquired by the moving handrail spray time acquisition unit 44 has elapsed, the chemical solution spraying control unit 46 activates the chemical solution spraying device main body 21a to spray the chemical solution, thereby more accurately spraying the chemical solution over the area of ​​the moving handrail 6 that is expected to be grasped by the passenger, allowing the passenger to use the moving handrail with peace of mind.

[0041] Although second detection unit 31a has been described as being provided in chemical solution sprayer main body 21a, the installation position is not limited as long as it is installed closer to passenger conveyor 1 than first detection unit 30a. Also, second detection unit 31a has been described as being configured to detect passengers' hands 11, but is not limited to being configured to detect passengers' hands 11, and may be configured to detect passengers attempting to board passenger conveyor 1. Even when the configuration of the second detection unit is not limited in this way, it is possible to spray the chemical solution over an area including the moving handrail 6 that passengers are likely to grab, allowing passengers to use the moving handrail with peace of mind.

[0042] Furthermore, in the liquid chemical spraying device 10a of the passenger conveyor 1 according to the first embodiment, the liquid chemical spraying device main body 21a has a second spray nozzle that sprays the liquid chemical onto the passenger's hand, the second detection unit 31a is provided on the liquid chemical spraying device main body 21a so as to detect the passenger's hand 11, and when the second detection unit 31a detects the passenger's hand 11, the liquid chemical spray control unit 46 activates the liquid chemical spraying device main body 21a to spray the liquid chemical from the second spray nozzle 15b onto the passenger's hand 11. This makes it possible to spray the liquid chemical both in the area of ​​the moving handrail 6 that the passenger is likely to grab and on the passenger's hand 11, allowing the passenger to use the moving handrail with greater peace of mind.

[0043] In addition, the first detection unit 30a may be provided in the liquid medicine sprayer main body 21a so as to detect the passenger's hand 11, and the liquid spray control unit 46 may be configured so that when the first detection unit 30a detects the passenger's hand 11, it activates the liquid medicine sprayer main body 21a and sprays the liquid medicine onto the passenger's hand 11 from the second spray nozzle 15b.

[0044] Furthermore, in the chemical spraying device 10a of the passenger conveyor 1 according to embodiment 1, when the first detection unit 30a detects a passenger, the chemical spraying control unit 46 puts the chemical spraying device main body 21a into a standby state in which it is operable, thereby allowing the chemical spraying device main body 21a to spray the chemical liquid smoothly and more accurately onto the moving handrail 6 or the passenger's hand 11.

[0045] Furthermore, in the chemical liquid spraying device 10a for the passenger conveyor 1 according to the first embodiment, the chemical liquid spraying device main body 21a is fixed to the balustrade 5 of the passenger conveyor 1 in a section that forms the entrance to the passenger conveyor 1. By fixing the chemical liquid spraying device main body 21a to the passenger conveyor 1 in this way, space is freed up above members that are provided near the entrance to the passenger conveyor 1, such as the boarding and alighting board 100a, allowing passengers to use the passenger conveyor 1 smoothly.

[0046] Furthermore, in the chemical spraying device 10a of the passenger conveyor 1 according to embodiment 1, the chemical spraying device main body 1a is fixed to the railing 5 of the passenger conveyor 1 in the manual section, allowing passengers to grab the moving handrail 6 from sections farther from the entrance, thereby enabling passengers to move more safely.

[0047] The devices used in the first detectors 30a, 30b and the second detector 31a are not limited. For example, the first detectors 30a, 30b may be cameras, and passengers may be detected using the cameras. For example, the second detector 31a may be a pedal provided on the boarding / alighting platform 100a, and the passenger's hand 11 may be detected when the passenger steps on the pedal. Furthermore, the location of the second detector 31a is not limited as long as it is installed between the first detectors 30a, 30b and the entrance to the passenger conveyor. For example, the first detectors 30a, 30b may be provided in the inlet 8, and the second detector 31a may be provided on the balustrade 5 in a section located further forward than the inlet 8 in the moving direction A of the passenger conveyor 1.

[0048] The location where the chemical solution sprayer main body 21a is installed is not limited. For example, it may be configured to be installed on the left balustrade 5 or on the balustrades 5 on both sides.

[0049] The direction of movement of the steps 4 of the passenger conveyor 1 is not limited. For example, the direction of movement may be from the upper floor 2b to the lower floor 2a. In this case, the passengers may use the chemical solution spray device 10b.

[0050] The specific configuration of the chemical solution sprayer main body 21a is not limited as long as the chemical solution sprayer main body 21a has at least a configuration for spraying the chemical solution from the first spray nozzle onto the moving handrail 6.

[0051] Embodiment 2 The configuration of the chemical liquid spray device 10c in embodiment 2 will be described. Figure 7 is a diagram showing the configuration of the chemical liquid spray device 10c in embodiment 2. The chemical liquid spray device 10c in embodiment 2 differs from the chemical liquid spray device 10a in embodiment 1 in that it has a configuration that detects when the remaining amount of chemical liquid is reduced and notifies the user of this. Note that parts that are the same as or equivalent to those in embodiment 1 are given the same reference numerals and descriptions thereof will be omitted.

[0052] 7, the liquid spray control device 40b includes a spray count measuring unit 50, a spray count determining unit 51, and a notification unit 52.

[0053] The spray count measuring unit 50 counts the number of times the liquid spray device main body 21a has sprayed the liquid, which is received from the liquid spray control unit 46.

[0054] Spray count determination unit 51 determines whether the number of sprays of the liquid medicine measured by spray count measurement unit 50 is equal to or greater than a predetermined value. The predetermined value is determined from the amount of liquid medicine in tank 13 and the amount of liquid medicine supplied per spray. For example, if the amount of liquid medicine in tank 13 is 100 ml and the amount of liquid medicine supplied per spray is 1 ml, the predetermined value is set to 80.

[0055] The notification unit 52 notifies that the number of times the chemical solution has been sprayed has reached a predetermined value or more. The notification unit 52 notifies, for example, an external maintenance company 53.

[0056] As described above, by providing the spray count measurement unit 50 that measures the number of times the chemical solution sprayer main body 21a has sprayed the chemical solution, the spray count determination unit 51 that determines whether the number of times the chemical solution has been sprayed measured by the spray count measurement unit 50 is equal to or greater than a predetermined value, and the notification unit 52 that notifies that the number of times the chemical solution has been sprayed has exceeded the predetermined value, it is possible to replenish the chemical solution when the remaining amount is low. This allows passengers to use the moving handrail with greater peace of mind.

[0057] The configuration for determining whether the remaining amount of liquid medicine has decreased is not limited. Fig. 8 is a diagram showing the configuration of liquid medicine spray device 10d, which is a modified example of liquid medicine spray device 10c in embodiment 2. Liquid medicine spray device 10d determines whether the remaining amount of liquid medicine has decreased by including, in liquid medicine spray device main body 21a, liquid medicine remaining amount measuring unit 54 that measures the remaining amount of liquid medicine, and liquid medicine remaining amount determining unit 55 that determines whether liquid medicine remaining amount measuring unit 54 is equal to or less than a predetermined remaining amount. Liquid medicine remaining amount measuring unit 54 may be, for example, a liquid level sensor that detects changes in the surface of the liquid installed in tank 13, or a weight sensor that measures the remaining weight of the liquid installed in tank 13.

[0058] The configurations described in the above embodiments are merely examples of the contents of the present disclosure, and may be combined with other known technologies.
