DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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. Moreover, the passenger conveyor 1 is formed, from the lower floor 2a to the upper floor 2b, with a lower floor smooth 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 smooth section 206.

[0011] In Fig. 1, the passenger conveyor 1 includes a truss 3, a plurality of steps 4 supported by the truss 3 and connected endlessly, a pair of balustrades 5 provided on the truss 3 and provided on both sides of the width direction of the steps 4 along the moving direction, a moving handrail 6 provided on the upper part of the pair of balustrades 5 and moving in synchronization with the steps 4, a skirt guard 7 provided on the lower part of the pair of balustrades 5, inlets 8 provided on both ends of the skirt guard 7 for reeling out the moving handrail 6, a driving device 9 (not shown) for supplying power so that the moving handrail 6 rotates around the balustrade 5, boarding and alighting plates 100a, 100b provided on the lower floor 2a and the upper floor 2b for passengers to get on and off the passenger conveyor 1, and chemical spray devices 10a, 10b. In this embodiment, the moving direction of the steps 4 of the passenger conveyor 1 is a moving direction A from the lower floor 2a to the upper floor 2b.

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

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

[0014] Next, the liquid spraying device main body 21a will be described. The liquid spraying device main body 21a is provided in a section that constitutes an entrance in the moving direction of a plurality of steps of the passenger conveyor. In addition, the liquid spraying device main body 21a is fixed to the balustrade 5 provided on the right side when looking at the upper floor 2b from the lower floor 2a, for example. The liquid spraying device main body 21a is fixed to the balustrade 5 in a section that constitutes the entrance of the passenger conveyor 1. Here, the section that constitutes the entrance of the passenger conveyor 1 refers to a section in the manual part or horizontal part of the floor where the entrance is provided, and in FIG. 1, it refers to a section in the lower floor manual part 200 or the lower floor water straight part 201. In addition, in order for passengers to move safely by holding the moving handrail 6, it is desirable to fix the position of the balustrade 5 to which the liquid spraying device main body 21a is fixed to the manual part, which is a section closer to the entrance.

[0015] Fig. 3 is a diagram showing a 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 inside. A first spray nozzle 15a is provided on the lower surface of the tank mounting portion 12a, and a second spray nozzle 15b is provided on the upper surface of the tank mounting portion 12a, and 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 portion 30a and is provided for the purpose of spraying the medicinal liquid on the moving handrail 6. The second spray nozzle 15b corresponds to the second detection portion 31a described later and is provided for the purpose of spraying the medicinal liquid on the passenger's hand 11. The balustrade fixing portion 12b is, for example, made of metal, and is provided so as 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] The tank 13 contains a liquid medicine therein. The tank 13 can contain a liquid medicine having at least one of a germ-removing action, a germicidal action, and a disinfecting action. The tank 13 also contains, for example, a spray unit 14 therein.

[0018] Here, the term "bactericidal action" refers to the action of removing bacteria or viruses to reduce their numbers. The means of removing bacteria or viruses is not limited, and refers to, for example, removing bacteria or viruses by killing or washing them away. The term "germicidal action" refers to the action of killing bacteria or viruses to reduce their numbers. The term "disinfectant 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] In addition, the chemicals used must be safe and hypoallergenic enough that they will not cause any harm to passengers if they come into contact with their faces or eyes. Such chemicals include diluted liquids of the chemicals in question.

[0020] The spray unit 14 has 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 the chemical liquid in the tank 13 becomes small. The pipes 14b are provided so as to 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 the chemical liquid sprayed by the spray pump 14a at one time is set to an amount sufficient to sufficiently sterilize, sterilize, and disinfect the moving handrail 6 in the range that is assumed to be grasped by the passenger for the first spray nozzle 15a, and is set to an amount sufficient to sufficiently sterilize, sterilize, and disinfect the hands 11 of the passenger for the second spray nozzle 15b. The spray pump 14a can set not only the amount of the chemical liquid sprayed, but also the spray time 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 liquid spray control device 40a will be described. The liquid 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 storage unit 45, and a liquid spray control unit 46. The configuration that realizes the function of the liquid spray control device 40a may be disposed in the liquid spray device main body 21a, or may be disposed near or far from the liquid spray device main body 21a.

[0023] The first determination unit 41 determines whether or not the first detection unit 30a has detected a passenger about to board the passenger conveyor 1. The first determination unit 41 may be configured to perform the 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 or not 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 a 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 strict 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 showing the waiting time before starting spraying the liquid medicine onto the moving handrail 6, corresponding to the walking speed of the passenger. Here, the waiting time before starting spraying the liquid medicine onto the moving handrail 6 indicates the waiting time before starting spraying the liquid medicine onto the moving handrail 6, which makes it possible to spray the liquid medicine including the range of the moving handrail 6 that is estimated to be grabbed by the passenger from the walking speed of the passenger. For example, as shown in FIG. 4, when the walking speed of the passenger is 60 m / min, if the spraying of the liquid medicine onto the moving handrail 6 is started 0.5 seconds after the first detection unit 30a detects the passenger, it is possible to spray the liquid medicine including the range 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 liquid 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 liquid spray control unit 46.

[0028] The liquid spray control unit 46 controls the operation of the liquid spray device main body 21a to spray the liquid. When the first detection unit detects a passenger, the liquid spray control unit 46 sets the liquid spray device main body 21a to a standby state in which the liquid spray device main body 21a is operable. When the liquid spray control unit 46 receives a signal indicating a standby time before starting to spray the liquid onto the moving handrail 6, the liquid spray control unit 46 operates the liquid spray device main body 21a and sprays the liquid onto the moving handrail 6 from the first spray nozzle 15 when the time has elapsed since the first detection unit 30a detected the passenger. When the second detection unit 31a detects the passenger's hand 11, the liquid spray control unit 46 operates the liquid spray device main body 21a and sprays the liquid onto the passenger's hand 11 from the second spray nozzle 15b.

[0029] Here, a description will be given of a hardware configuration of the liquid spray control device 40a according to embodiment 1. Fig. 5 is a diagram showing a hardware configuration of the liquid spray control device 40a in embodiment 1. The liquid spray control device 40a is realized by a computer such as a personal computer or a microcontroller.

[0030] The liquid 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 loads an operating program stored in a secondary storage device 1004 into a memory 1002 and executes the program, thereby realizing each function of the liquid spray control device 1000.

[0032] The memory 1002 is a main storage device constituted by, for example, a RAM (Random Access Memory). The memory 1002 stores a program 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 a program.

[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 outputs from the first detection unit 30a and the second detection unit 31a, and inputs and outputs 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 liquid spray control device 40a and programs executed by the processor 1001.

[0035] Next, the operation of the liquid spraying device 10a of the passenger conveyor 1 according to the embodiment 1 will be described. Fig. 6 is a flowchart showing the operation of the liquid spraying device 10a of the passenger conveyor 1 according to the embodiment 1. The operation of the liquid spraying device 10b has the same configuration as that of the 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 sets the liquid spray device main body 21a to 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 detects the hand 11 of a passenger who is about to board the passenger conveyor 1 (S3). When the second detection unit 31a detects the hand 11 of the passenger (YES in S3), the liquid spray control unit 46 activates the liquid spray device main body 21a to spray the liquid from the second spray nozzle 15b onto the hand 11 of the passenger (S4). In addition, 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 hand 11 of the passenger, and the distance between the first detection unit 30a and the second detection unit 31a (S5). Furthermore, when the second detection unit 31a does not detect the hand 11 of the passenger (YES in S3), the second determination unit 42 again determines whether or not the second detection unit 31a has detected the hand 11 of the passenger.

[0038] Next, the moving handrail spray time acquisition unit 44 acquires from the 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 the 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 timing when the first detection unit 30a detected the passenger, it activates the medicinal liquid spray device main body 21a to spray the medicinal liquid onto the moving handrail 6 from the first spray nozzle 15a (S7).

[0039] As described above, the liquid chemical spraying device 10a for the passenger conveyor 1 in embodiment 1 is provided with: a liquid chemical spraying device main body 21a that is provided in a section that constitutes the entrance in the moving direction of the multiple steps 4 of the passenger conveyor 1, and sprays a liquid chemical having at least one of a sterilizing, germicidal, and disinfecting effect from a first spray nozzle onto the moving handrail 6; a first detection unit 30a and a second detection unit 31a that detect passengers who are about 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 liquid chemical spray control unit 46 that activates the liquid chemical spraying device main body 21a and sprays the liquid chemical based on the walking speed calculated by the walking speed calculation unit 43. This makes it possible to spray the liquid chemical including in the range of the moving handrail 6 that the passenger is expected to grab, allowing passengers to use the moving handrail with peace of mind.

[0040] In addition, the chemical solution spraying device 10a of the passenger conveyor 1 in embodiment 1 is equipped with a memory unit 45 that stores a 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 spray control unit 46 activates the chemical solution spraying device main body 21a to spray the chemical solution, thereby making it possible to more accurately spray the chemical solution including the area of ​​the moving handrail 6 that is assumed to be grasped by the passenger, allowing the passenger to use the moving handrail with peace of mind.

[0041] Although the second detection unit 31a is described as being provided in the liquid spray device main body 21a, the location at which it is installed is not limited as long as it is installed closer to the passenger conveyor 1 than the first detection unit 30a. Also, the second detection unit 31a has been described as being configured to detect the passenger's hand 11, but is not limited to being configured to detect the passenger's hand 11, and may be configured to detect a passenger attempting to board the passenger conveyor 1. Even if the configuration of the second detection unit is not limited in this way, the liquid can be sprayed to include the range of the moving handrail 6 that a passenger is expected to grab, allowing the passenger to use the moving handrail with peace of mind.

[0042] Moreover, in the liquid medicine spraying device 10a of the passenger conveyor 1 according to the first embodiment, the liquid medicine spraying device main body 21a has a second spray nozzle that sprays the liquid medicine onto the passenger's hand, the second detection unit 31a is provided in the liquid medicine spraying device main body 21a so as to detect the passenger's hand 11, and the liquid medicine spray control unit 46 operates the liquid medicine spraying device main body 21a when the second detection unit 31a detects the passenger's hand 11, and causes the liquid medicine to be sprayed from the second spray nozzle 15b onto the passenger's hand 11. This makes it possible to spray the liquid medicine both onto the range of the moving handrail 6 that the passenger is expected to grab and onto 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 medicinal liquid spray device main body 21a so as to detect the passenger's hand 11, and the liquid spray control unit 46 may be configured to activate the medicinal liquid spray device main body 21a when the first detection unit 30a detects the passenger's hand 11, and spray the medicinal liquid onto the passenger's hand 11 from the second spray nozzle 15b.

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

[0045] In addition, in the liquid spraying device 10a of the passenger conveyor 1 according to the first embodiment, the liquid spraying device main body 21a is fixed to the railing 5 of the passenger conveyor 1 in a section that constitutes the entrance of the passenger conveyor 1. By fixing the liquid spraying device main body 21a to the passenger conveyor 1 in this manner, a space is freed above a member provided near the entrance of the passenger conveyor 1, such as the boarding and disembarking board 100a, and passengers can use the passenger conveyor 1 smoothly.

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

[0047] The devices used in the first detection units 30a, 30b and the second detection unit 31a are not limited. For example, the first detection units 30a, 30b may be cameras, and passengers may be detected using the cameras. For example, the second detection unit 31a may be a pedal provided on the boarding / alighting board 100a, and the passenger's hand 11 may be detected by the passenger stepping on the pedal. Furthermore, the location of the second detection unit 31a is not limited as long as it is installed at a position between the first detection units 30a, 30b and the entrance of the passenger conveyor. For example, the first detection units 30a, 30b may be provided in the inlet 8, and the second detection unit 31a may be provided on the balustrade 5 of a section installed in a direction forward of the inlet 8 in the moving direction A of the passenger conveyor 1.

[0048] The location where the liquid sprayer body 21a is provided is not limited. For example, the liquid sprayer body 21a may be provided on the left balustrade 5, or on both balustrades 5.

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

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

[0051] Embodiment 2 The configuration of the liquid medicine spraying device 10c in the second embodiment will be described. Fig. 7 is a diagram showing the configuration of the liquid medicine spraying device 10c in the second embodiment. The liquid medicine spraying device 10c in the second embodiment differs from the liquid medicine spraying device 10a in the first embodiment in that it has a configuration for detecting a decrease in the remaining amount of the liquid medicine and notifying the user of this. Note that the same or corresponding parts as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

[0052] In FIG. 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 measures the number of times that the liquid sprayer body 21a has sprayed the liquid, which is received from the liquid spray control unit 46.

[0054] The spray count determination unit 51 determines whether the number of sprays of the liquid medicine measured by the 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 the tank 13 and the amount of liquid medicine supplied per spray. For example, when the amount of liquid medicine in the 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 measuring unit 50 that measures the number of times the liquid spray device main body 21a has sprayed the liquid, the spray count determining unit 51 that determines whether the number of times the liquid sprayed measured by the spray count measuring unit 50 is equal to or greater than a predetermined value, and the notification unit 52 that notifies that the number of times the liquid sprayed has reached a predetermined value or greater, it is possible to replenish the liquid when the remaining amount of the liquid decreases. This allows passengers to use the moving handrail with greater peace of mind.

[0057] The configuration for determining that the remaining amount of the liquid medicine has decreased is not limited.
