It includes an opening/closing control section 9, a non-contact switch unit 11 having a non-contact sensor 10, and a chemical liquid spraying device 2 formed on one vertical frame 3, having a chemical liquid tank 12 for storing a chemical liquid.

The pair of vertical frames 3 are vertical members that extend vertically and have guide rails 14 for guiding the ends of the sheet body 4 formed therein. The pair of vertical frames 3 are formed hollow inside, and the cover body 15 of the non-contact switch unit 11 in which the non-contact sensor 10 of the chemical liquid spraying device 2 is formed is attached to the surface of the vertical frame 3. A hole 13 into which a chemical tank 12 can be inserted is formed below the non-contact switch unit 11. A hole cap 16 is fitted into the hole 13 and closed so as to be openable and closable.

The sheet body 4 is a rectangular curtain body made of a synthetic resin material having flexibility, weather resistance, and light-transmitting or light-blocking properties as required. The upper end of the sheet body 4 is attached to the circumferential surface of the winding shaft 5 along the axial direction. Guide protrusions (not shown) are provided on the left and right sides of the seat body 4, and the seat body 4 is housed in a state in which it is inserted into the guide rail 14 and engaged with the guide protrusion so as to be slidable up and down. Thereby, the seat body 4 performs smooth lifting and lowering operations while maintaining tension in the width direction. Further, a lower bar 17 is formed at the lower end of the sheet body 4, which also serves as a weight portion and biases the sheet body 4 downward.

The winding shaft 5 is housed in a sheet case 6, and can wind up and unwind the sheet body 4 by rotating around its axis. Further, the opening/closing drive section 7 is a motor that can rotate the winding shaft 5 in the forward direction and the reverse direction. The seat case 6 houses the winding shaft 5 and the opening/closing drive unit 7 therein, and is provided with a human sensor 8 at the lower center for detecting a person or the like approaching the seat shutter 1. Further, inside the seat case 6, an opening/closing control section 9 is provided which controls driving of the opening/closing drive section 7 to control opening/closing of the seat shutter 1. The seat shutter 1 can be switched to automatic opening/closing or manual opening/closing, and when the opening/closing control unit 9 is set to "automatic opening/closing", the opening/closing control unit 9 automatically opens and closes the shutter based on the detection by the human sensor 8 provided in the seat case 6. The opening and closing of the sheet shutter 1 is controlled when the sheet shutter 1 is opened and closed, and when "manual opening and closing" is set, the opening and closing of the sheet shutter 1 is controlled by placing a hand over the non-contact sensor 10.

The chemical spray device 2 includes a non-contact switch unit 11 that is attached to the surface of the vertical frame 3 of the sheet shutter 1 and operates and controls the chemical spray device 2, and a non-contact switch unit 11 that is inserted into the vertical frame 3 and that sprays a chemical solution for hand disinfection. It is equipped with a medicinal solution tank 12 for storing a medicinal solution, and sprays a medicinal solution for hand disinfection based on detection by a non-contact sensor 10 provided in a non-contact switch unit 11.

As shown in FIGS. 2 to 4, the non-contact switch unit 11 includes a cover body 15, a non-contact sensor 10 built into the cover body 15, a sensor control unit 18 that controls the non-contact sensor 10, and a chemical liquid. A nozzle 20 in which a spray nozzle 19 is formed to spray, a pump control unit 22 that controls a chemical pump 21 that supplies a chemical to the spray nozzle 19, and a remaining amount determination unit (not shown) that determines the remaining amount of chemical in the chemical tank 12. and a remaining amount warning section that warns of a shortage of the remaining amount of the chemical solution based on the judgment of the remaining amount determining means. The non-contact sensor 10, the sensor control section 18, and the pump control section 22 are fixed to the inside of the cover body 15 with screws. The sensor control section 18 and the pump control section 22 are rectangular circuit boards, and are fixed inside the cover body 15 with a resin collar and an insulating sheet as a spacer sandwiched therebetween. As shown in FIG. 5, the non-contact switch unit 11 is fixed by fitting the cover body 15 into the switch bracket 33 which is fixed to the vertical frame 3 with screws.

The cover body 15 is an exterior made of resin and fixes each part constituting the non-contact switch unit 11 inside. The cover body 15 is formed to protrude from the vertical frame 3 in a horizontal direction perpendicular to the sheet surface of the sheet shutter 1. The cover body 15 has a rectangular protruding plane 34 formed parallel to the seat surface, an upper surface 35 extending from the upper edge of the protruding plane 34 toward the vertical frame 3, and a lower surface extending from the lower edge of the protruding plane 34 toward the vertical frame 3. 36, and left and right side surfaces 37 extending from the left and right side edges of the protruding plane 34 toward the vertical frame 3, respectively. The upper surface 35 is formed with a downward slope toward the protruding side of the cover body 15, and the lower surface 36 is formed with an upward slope toward the protruding side of the cover body 15. The left and right side surfaces 37 are vertical planes perpendicular to the sheet surface, and are trapezoidal. A design sheet with a palm drawn on it is pasted on the protruding plane 34 of the cover body 15 to indicate the position where the hand is held up. A circular opening is provided below the design sheet on the protruding surface, and four circular arc holes are formed around the outer periphery of the circular opening. The circular opening suppresses attenuation of microwaves emitted from the non-contact sensor 10 and microwaves reflected from the detection target. In addition, the four arcuate holes allow the non-contact sensor 10 to transmit light that indicates the state of the non-contact sensor 10 and appear on the surface, thereby informing the outside that the non-contact sensor 10 is on standby or that an object has been detected. to be displayed.

A screw hole for fixing the nozzle 20 is formed in the inclined lower surface 36 of the cover body 15. Although specific illustrations are omitted, the nozzle 20 is provided with a rubber washer, a sealing material, a dimension adjustment washer, etc., and is attached to the lower surface 36 of the cover body 15, so that the chemical solution can be sprayed while preventing liquid leakage. I have to. Further, a small hole into which the LED light emitting element 23 can be inserted is formed in the lower surface 36. The LED light emitting element 23 inserted into the small hole is controlled by the pump control section 22 to emit red light, thereby functioning as a remaining amount warning section that warns of insufficient amount of the chemical solution in the chemical solution tank 12. be.

As the shape of the cover body 15 is as described above, the upper surface 35 is formed with a downward slope toward the protruding side, thereby preventing dust from accumulating on the upper surface 35, and making the cover body 15 sanitary. I can do it. Further, since the lower surface 36 of the cover body 15 is formed with an upward slope toward the protrusion side, and the spray port 19 is formed on the lower surface 36 of the cover body 15, the chemical solution can be sprayed diagonally downward. , it is possible to suppress the chemical liquid from being applied to the cover body 15 and the sheet shutter 1.

The non-contact sensor 10 is screwed inside the cover body 15. The non-contact sensor 10 is a microwave type non-contact sensor 10 that detects an object by receiving reflected microwaves, for example. The non-contact sensor 10 can detect a palm held up at a distance of, for example, 20 mm or less. Note that the method and detection distance range of the non-contact sensor 10 are not limited to those described above, and any sensor may be used as long as it is suitable for use as an open/close switch for the sheet shutter 1 and a switch for the chemical spray device 2 for hand disinfection. good.

The sensor control unit 18 is a board that controls the non-contact sensor 10 and transmits the detection of the non-contact sensor 10 to the pump control unit 22. The non-contact sensor 10 is formed to protrude from the sensor control section 18. The sensor control unit 18 controls the external display of the status of the non-contact sensor 10, such as that it is on standby or that there has been a detection, using light emission or sound from the non-contact sensor 10, and also displays the status of the non-contact sensor 10, such as that it is on standby or that a detection has been made, through the connection cable. Information indicating that the non-contact sensor 10 has been detected is output to the pump control unit 22. Further, the sensor control unit 18 may have an input switch that accepts settings such as light emission and answerback sound of the non-contact sensor 10, or accepts settings such as the detection distance range of the non-contact sensor 10.

The nozzle 20 has a cylindrical shape with a threaded outer periphery, and is fixed by screwing into a threaded hole in the lower surface 36 of the cover body 15. The nozzle 20 is made of metal such as stainless steel, and the spray port 19 is formed to pass through the nozzle 20 . The spray nozzle 19 is formed in a shape capable of spraying the chemical solution over a certain range. A supply pipe 32 connected from a chemical pump 21 is connected to the nozzle 20, and when the chemical pump 21 is driven, a chemical is supplied to the nozzle 20 through the supply pipe 32, and the chemical is sprayed from the spray port 19.

The pump control unit 22 is a board that controls the drive of the chemical liquid pump 21 based on the signal from the sensor control unit 18. The pump control unit 22 controls the delay time (spray delay time) from when the non-contact sensor 10 detects a detection target until the chemical liquid pump 21 is driven, and the amount of chemical liquid that the chemical liquid pump 21 supplies to the spray port 19 (spray A rotary switch is formed that can set the strength), the time from driving the chemical pump 21 to transmitting a signal to open the sheet shutter 1 (startup delay time), and the capacity of the chemical tank 12. In this way, the pump control unit 22 can adjust the spray delay time, spray intensity, startup delay time, and capacity of the chemical tank 12, so it can be adjusted optimally depending on the installation location and condition of the sheet shutter 1. I can do it.

Note that the spray delay time can be adjusted in 10 steps from 0 seconds to 3 seconds, for example. Further, the spray intensity is expressed by the length of spraying time, and can be adjusted in 10 steps from 0 seconds to 3 seconds, for example. That is, the longer the injection time is, the greater the amount of the chemical liquid to be injected. The startup delay time can also be adjusted in 10 steps from 0 seconds to 3 seconds. The capacity of the chemical solution tank 12 can be adjusted in 10 steps from 0.1 liters to 3 liters.

The pump control unit 22 counts the number of times the chemical liquid pump 21 is driven to spray the chemical liquid after replenishing the chemical liquid tank 12 with the chemical liquid, and the count is stored in a nonvolatile memory of the pump control unit 22 . The pump control unit 22 is configured to be able to send a signal also to the opening/closing control unit 9 of the sheet shutter 1, and the opening/closing control unit receives information from the sensor unit indicating that the non-contact sensor 10 has detected a detection target. 9, the opening/closing control unit 9 can control the opening/closing of the sheet shutter 1 based on the detection by the non-contact sensor 10.

The remaining amount determining means is a function provided in the pump control unit 22, and is based on the capacity of the chemical liquid tank 12, the spray intensity, and the number of times of spraying counted by the pump control unit 22, which are set in advance by the rotary switch. It is determined whether the remaining amount of the chemical solution in the tank 12 has decreased to the extent that replenishment is necessary. Specifically, the amount of chemical solution used per spray is determined based on the spray intensity, the total amount of chemical solution used is calculated by multiplying the amount of drug solution used per time by the number of times of spraying, and the capacity of the chemical solution tank 12 is determined. A process is performed to calculate the remaining amount of the chemical solution in the chemical solution tank 12 by subtracting the total amount of the drug solution used from. If it is determined that the remaining amount of the chemical solution in the chemical solution tank 12 is less than or equal to a predetermined value, an output is output to the remaining amount warning section to warn that the remaining amount of the drug solution is insufficient. Here, the predetermined value or less is, for example, a value of 10% or less of the capacity of the chemical liquid tank 12. The predetermined value is not limited to this, and it is sufficient that the shortage of the chemical solution can be outputted at a timing that allows replenishment before the chemical solution in the chemical solution tank 12 actually runs out.

Note that the remaining amount determining means may be a processing program recorded in the pump control section 22, or may be a physically incorporated processing circuit. Further, the program is not limited to one that is incorporated in the pump control section 22, but may be a program recorded in a computer that is communicably connected to the pump control section 22 inside or outside the sheet shutter 1. Further, the remaining amount determining means is not limited to one that calculates the remaining amount of the chemical solution from the spray intensity or the number of times of spraying, and may be, for example, various water level sensors physically provided within the chemical solution tank 12.

In this embodiment, the remaining amount warning section is a red LED light emitting element 23 inserted into a small hole formed in the lower surface 36 of the cover body 15, and the pump control section 22 uses a remaining amount determining means to control the amount of chemical solution. When it is determined that the remaining amount is less than a predetermined value, the LED light emitting element 23 is made to emit red light to warn that the remaining amount of the chemical solution in the chemical solution tank 12 is insufficient. Note that the remaining amount warning section is not limited to one that uses light emission, but may also use a sound such as a buzzer to warn of insufficient remaining amount, or may alert the user of the sheet shutter 1 via an external network. It may also be a warning to the administrator that the remaining amount is insufficient.

The non-contact switch unit 11 includes a cover body 15, a non-contact sensor 10, a sensor control section 18, a pump control section 22, a nozzle 20, and a remaining amount determining means, which are held by the cover body 15. Since it is equipped with an LED light emitting element 23 (remaining amount warning part), all you need to do is remove the existing operation panel provided on the vertical frame 3, attach the cover body 15, and perform the prescribed wiring and piping. To provide a sheet shutter 1 equipped with a chemical liquid spraying device 2 at low cost, in which the chemical liquid spraying device 2 can be housed within the vertical frame 3 of an existing sheet shutter 1, without changing the entire design of the sheet shutter 1. I can do it.

As shown in FIGS. 6 and 7, the chemical solution tank 12 includes a storage section 24 that is long in the vertical direction, a covering material 25 that covers the storage section 24, a resin bottom section 26 formed at the lower end, and an upper end that can be opened and closed. and a lid body 27 that enables. The storage section 24 has a cylindrical shape formed by processing a polyethylene sheet into a bag shape, and has a diameter of about 30 mm and a length of 500 mm, for example. The covering material 25 is formed using the remaining material of the sheet body 4 and is adhered to the surface of the storage section 24 to reinforce the storage section 24. An eyelet 28 is formed at the upper end of the covering material 25, and a fixing string 29 for fixing the chemical solution tank 12 inside the vertical frame 3 is tied thereto. A lid 27 is formed at the upper end of the chemical liquid tank 12 so as to be openable and closable. An end portion of a connecting string 30 is fixed to the lid body 27. The chemical liquid tank 12 is housed inside the vertical frame 3 of the sheet shutter 1, and unlike the case where the chemical liquid spraying device 2 is provided separately from the sheet shutter 1, it can be prevented from obstructing the entrance/exit. The chemical liquid tank 12 has flexibility and can easily change its shape, so the chemical liquid tank 12 can be inserted into various vertical frames 3 having different cross-sectional shapes of various sheet shutters 1. The chemical spray device 2 can be attached to various sheet shutters 1.

One end of a connecting cord 30 is fixed to the surface facing the inside of the vertical frame 3 of a hole cap 16 that opens and closes the hole 13 formed in the vertical frame 3, and is fixed to the upper end of the chemical solution tank 12. The other end of the connecting string 30 is fixed to the lid body 27. The hole 13 formed in the vertical frame 3 is a circular hole having a diameter larger than at least the diameter of the chemical liquid tank 12. In this embodiment, the hole 13 is formed to have a diameter of 36.5 mm. The connecting string 30 is composed of an appropriate connecting member such as a resin string, a fiber string, a chain body, a metal-containing resin cord, or the like.

A chemical liquid pump 21 is fixed to the side surface of the chemical liquid tank 12. The chemical liquid pump 21 has one end connected to a suction pipe 31 near the bottom 26 of the chemical liquid tank 12, and the other end of a suction pipe 31 connected to the liquid chemical pump 21, and sucks the chemical liquid through a supply pipe 32 to a nozzle 20 in which a spray port 19 is formed. Supply chemical solution. The driving of the chemical liquid pump 21 is controlled by a pump control unit 22, and the pump control unit 22 controls the driving of the chemical liquid pump 21 based on information including detection by the non-contact sensor 10.

When replenishing the chemical solution tank 12 with a chemical solution, first, the hole cap 16 is removed from the hole 13 of the vertical frame 3, as shown in FIG. Then, when the hole cap 16 is pulled in a direction away from the vertical frame 3, the upper end of the chemical solution tank 12 is pulled out from the hole 13 by the connecting string 30, as shown in FIG. Next, the lid body 27 is removed from the chemical liquid tank 12, and the chemical liquid tank 12 is replenished with the chemical liquid. Then, the lid 27 is attached to the upper end of the chemical liquid tank 12 again to close the chemical liquid tank 12. Thereafter, as shown in FIG. 10, the upper end of the chemical tank 12 is pushed into the vertical frame 3 through the hole 13, the connecting string 30 is also inserted into the vertical frame 3, and the hole 13 is closed with the hole cap 16. . The chemical tank 12 has flexibility, and the hole 13 is formed larger than the chemical tank 12, so the upper end of the chemical tank 12 can be pulled out from the hole 13, and the chemical solution can be removed. Replenishment can be made easy.

Next, an example of a process mainly performed by the pump control unit 22 when the sheet shutter chemical spray device 2 configured as described above sprays a chemical will be described with reference to FIG. 11. In the chemical liquid spraying process, first, it is determined whether the setting of the sheet shutter 1 is "automatic opening/closing" or "manual opening/closing" (S100). "Automatic opening/closing" is a setting in which the seat shutter 1 is automatically opened when a person passing through the entrance/exit where the seat shutter 1 is installed approaches, and the seat shutter 1 is automatically opened when a person passes through the entrance/exit where the seat shutter 1 is installed. Based on this, the opening/closing control section 9 of the sheet shutter 1 drives the opening/closing drive section 7 to open the sheet shutter 1. Further, "manual opening/closing" is a setting in which the seat shutter 1 is opened when a person passing through the entrance/exit where the seat shutter 1 is provided places his/her hand over the non-contact sensor 10 . Although the sheet shutter 1 of this embodiment can be set to either "automatic opening/closing" or "manual opening/closing", the sheet shutter 1 of the present invention is a sheet shutter 1 that can only be set to "manual opening/closing". Good too.

If it is determined that the setting of the sheet shutter 1 is "manual opening/closing" (S100: Yes), then it is determined whether or not there is a detection by the non-contact sensor 10 (S101). When a hand is placed within a range of, for example, 20 mm in front of the cover body 15, the microwave emitted from the non-contact sensor 10 is reflected, and by detecting the reflected wave, the non-contact sensor 10 detects the object to be detected. The sensor control unit 18 detects the presence and sends a signal to the pump control unit 22 to the effect that the detection has occurred. Then, upon receiving the signal, the pump control unit 22 determines that there has been a detection by the non-contact sensor 10 (S101: Yes). On the other hand, if the pump control unit 22 does not receive the signal, it determines that there is no detection by the non-contact sensor 10 (S101: No), and waits for processing.

If it is determined that there is a detection by the non-contact sensor 10 (S101: Yes), then the pump control unit 22 determines whether the injection delay time has elapsed (S102). Specifically, the non-contact sensor 10 preset in the pump control unit 22 waits until a delay time elapses from when the detection target is detected to when the chemical liquid pump 21 is driven (S102: No), and the injection is started. When the delay time has elapsed (S102: Yes), the process proceeds to the next step.

In the next process, it is determined whether the sheet shutter 1 is closed (S103). If the sheet shutter 1 is closed (S103: Yes), it can be determined that the user is operating to open the sheet shutter 1 in order to pass through the entrance/exit where the sheet shutter 1 is installed. Proceed to processing for spraying. On the other hand, if the sheet shutter 1 is not closed (S103: No), the sheet shutter 1 is completely open, or the sheet shutter 1 is in the process of opening or closing. Since it can be determined that a hand is placed over the non-contact sensor 10 to close the shutter 1 or to stop the operation of the sheet shutter 1, there is no need to spray a chemical solution, and there is no need to close or stop the sheet shutter 1. A signal indicating that the operation should be performed is transmitted to the opening/closing control section 9 (S110), and the process is ended.

When proceeding to the process for spraying the chemical solution, the pump control unit 22 performs a process for driving the pump (S104). That is, in this process, when the non-contact sensor 10 detects a detection target, the elapsed time from the detection has passed the preset injection delay time, and the sheet shutter 1 is in the closed state, the chemical pump 21 is activated. When driven, the chemical solution is supplied to the spray port 19 and sprayed. The chemical solution is sprayed at a preset spray intensity. Specifically, the pump control unit 22 drives the chemical liquid pump 21 by energizing the chemical liquid pump 21 for a preset time, and supplies the chemical liquid to the spout. Therefore, when entering a predetermined section through the entrance/exit where the sheet shutter 1 is installed, if you place your hand over the non-contact sensor 10 to detect it in order to open the sheet shutter 1, after a predetermined period of time, the chemical solution will be released from the spray nozzle 19. Since the hands are sprayed and the hands can be disinfected by the operation of opening the sheet shutter 1, the hands can be disinfected reliably and without any inconvenience.

Then, when the chemical liquid pump 21 is driven (S104), a process is performed in which the fact that the chemical liquid has been sprayed once is stored in the nonvolatile memory of the pump control unit 22 (S105). Specifically, the number of times of spraying stored in the non-volatile memory is added once. Then, it is determined whether the remaining amount of the chemical solution in the chemical solution tank 12 is less than or equal to a predetermined value (S106). In this process, first, a process is performed to calculate the remaining amount of the chemical solution in the chemical solution tank 12, and when the calculated remaining amount of the drug solution is, for example, 10% or less of the capacity of the chemical solution tank 12, It is determined that the remaining amount of the chemical solution in the container is below a predetermined value. Specifically, the amount of chemical solution used per spray is determined based on the spray intensity set in the pump control unit 22, and the amount of chemical solution used per time and the number of sprays stored in the non-volatile memory are determined. The total amount of the chemical solution used is calculated by multiplying the total amount of the drug solution used, and the total amount of the drug solution used is subtracted from the capacity of the drug solution tank 12 set in the pump control unit 22 to calculate the remaining amount of the drug solution in the drug solution tank 12. It is determined whether the calculated value is 10% or less of the capacity of the chemical solution tank 12. In this process, the remaining amount of the chemical solution in the chemical solution tank 12 is calculated by a processing program or a processing circuit provided in the pump control unit 22, but it is calculated by a water level sensor physically provided in the chemical solution tank 12. It may be something that is measured.

If it is determined that the remaining amount of the chemical solution in the chemical solution tank 12 is below a predetermined value (S106: Yes), a process is performed to output a warning that the remaining amount is insufficient (S07), and the process proceeds to the next step. Specifically, the pump control unit 22 energizes the red LED light emitting element 23 inserted into the small hole formed in the lower surface 36 of the cover body 15 to cause the red LED light emitting element 23 to emit light or blink, thereby indicating that the remaining amount is insufficient. Show that. Note that this warning is not limited to light emission, and can be sent via light emission or blinking of the LED light emitting element 23, a buzzer sound, and an external network such as a wireless LAN to the ID of the administrator of the sheet shutter 1 when the remaining capacity is insufficient. One or more warnings may be issued, such as sending information to the effect.

Returning to step 106, if it is determined that the remaining amount of the chemical solution in the chemical solution tank 12 is greater than a predetermined value (S106: No), the process proceeds to the next step without outputting a warning that the remaining amount is insufficient. In the next step, it is determined whether the startup delay time has elapsed (S108). Specifically, the pump control unit 22 determines whether a period of time, which is preset in the pump control unit 22, has elapsed from driving the chemical pump 21 to transmitting a signal to open the sheet shutter 1. do. If it is determined that the activation delay time has elapsed (S108: Yes), a signal to the effect that the sheet shutter 1 should be opened is transmitted to the opening/closing control unit 9 (S109), and this process is ended. If it is determined that the startup delay time has not elapsed (S108: No), the process waits until the startup delay time has elapsed.

In this way, when the sheet shutter 1 is installed in "manual opening/closing" mode, the action of waving your hand over the non-contact sensor 10 to open the sheet shutter 1 triggers spraying of the chemical solution, and Since the opening operation is performed, those who pass through the entrance/exit where the sheet shutter 1 is formed must also disinfect their hands. Therefore, hands can be disinfected reliably and without any hassle. At this time, the chemical solution is sprayed only when the sheet shutter 1 is closed, so for example, when closing the sheet shutter 1 that has already been opened, or during the opening/closing operation of the sheet shutter 1. It is possible to prevent the chemical solution from being sprayed when hand disinfection is not required, such as when the disinfectant is turned off. Note that the sheet shutter chemical liquid spraying device 2 of the present invention may spray the chemical liquid whenever there is a detection by the non-contact sensor 10, regardless of whether the sheet shutter 1 is opened or closed.

On the other hand, if it is determined that the setting of the seat shutter 1 is "automatic opening/closing" (S100: No), the processing related to opening/closing the seat shutter 1 is performed based on the information of the human sensor 8 provided on the seat cover and the opening/closing control unit 9. Since the processing is performed through communication, the pump control unit 22 does not perform processing related to opening and closing of the sheet shutter 1, but only performs processing related to spraying of the chemical solution. Here, the process related to spraying the chemical solution is the same as when the sheet shutter 1 is set to "manual opening/closing", so a detailed explanation will be omitted.

If it is determined that the setting of the sheet shutter 1 is "automatic opening/closing" (S100: No), then it is determined whether or not there is a detection by the non-contact sensor 10 (S111). When the pump control unit 22 determines that the non-contact sensor 10 has detected the detection (S111: Yes), the pump control unit 22 proceeds with the process. On the other hand, if the pump control unit 22 determines that there is no detection by the non-contact sensor 10 (S111: No), it waits for processing.

If it is determined that the non-contact sensor 10 has detected (S111: Yes), then the pump control unit 22 determines whether the injection delay time has elapsed (S112). Specifically, the system waits until a delay time elapses from when the non-contact sensor 10 preset in the pump control unit 22 detects the detection target until the chemical liquid pump 21 is driven (S112: No), and the injection is started. When the delay time has elapsed (S112: Yes), the process proceeds to the next process for spraying the chemical solution.

When proceeding to the process for spraying the chemical solution, the pump control unit 22 performs a process for driving the pump (S113). That is, in this process, when the non-contact sensor 10 detects a detection target and the elapsed time from detection has elapsed a predetermined injection delay time, the chemical liquid pump 21 is driven and the chemical liquid is delivered to the spray nozzle. 19 and spraying is performed.

Then, when the chemical liquid pump 21 is driven (S113), a process is performed to store in the nonvolatile memory of the pump control unit 22 that the chemical liquid has been sprayed once (S114). Then, it is determined whether the remaining amount of the chemical solution in the chemical solution tank 12 is less than or equal to a predetermined value (S115). This process first calculates the remaining amount of the chemical solution in the chemical solution tank 12, and if the calculated remaining amount of the drug solution is a predetermined value, the remaining amount of the drug solution in the drug solution tank 12 is less than or equal to the predetermined value. I judge that there is.

If it is determined that the remaining amount of the chemical solution in the chemical solution tank 12 is below a predetermined value (S115: Yes), a process is performed to output a warning that the remaining amount is insufficient (S116), and the process ends. Returning to step 115, if it is determined that the remaining amount of the chemical solution in the chemical solution tank 12 is greater than a predetermined value (S115: No), the process is ended without outputting a warning that the remaining amount is insufficient.

In this way, since the spraying of the chemical solution and the opening/closing operation of the sheet shutter 1 are performed by holding the hand over the non-contact sensor 10, there is no need to touch a physical button, and the hands and fingers and the sheet shutter 1 can be kept cleaner. can be kept.

It goes without saying that the embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the idea of the present invention.

The chemical spraying device 2 for a sheet shutter and the sheet shutter 1 according to the present invention are suitable as the chemical spraying device 2 for a sheet shutter and the sheet shutter 1 used, for example, in factories, warehouses, offices, stores, and event venues.
