[0008] (Outline of this embodiment) (1) A work device according to the present disclosure is a work device that is installed in a factory having air conditioning equipment and performs specified work, and is equipped with a first communication unit that communicates with the air conditioning equipment and a control unit, and when the control unit determines that condensation will occur within the work device based on the temperature and humidity inside and outside the work device, the control unit executes a first determination process that determines whether condensation will occur within the work device based on the temperature and humidity inside and outside the work device, and a first change process that changes the settings of the air conditioning equipment via the first communication unit so as to suppress condensation within the work device.

[0009] In the above first judgment process, "based on the temperature and humidity inside and outside the work device" is not necessarily limited to being based on all four of the temperature inside the work device, the humidity inside the work device, the temperature outside the work device, and the humidity outside the work device; if possible, the judgment may be based on any three of these four, any two, or any one.

[0010] One of the problems caused by the temperature and humidity inside the work equipment is that condensation occurs on the circuit board on which the control unit is mounted, causing the circuit board to short out and break down. This problem generally occurs from the rainy season to summer. According to the above-mentioned operating device, if condensation occurs inside the operating device, the settings of the factory's air conditioning equipment are changed to suppress condensation inside the operating device, so that condensation can be suppressed without providing the operating device with a temperature control means or a humidity control means. Therefore, according to the above-mentioned operating device, condensation inside the operating device can be suppressed with a simple configuration.

[0011] (2) In the first determination process, the control unit may execute a first process to calculate an amount of saturated water vapor at which condensation will occur on an object within the working device based on a temperature of the object, and a second process to calculate an amount of moisture in the air outside the working device based on the temperature and humidity outside the working device, and may determine that condensation will occur within the working device if the amount of moisture in the air calculated in the second process exceeds the amount of saturated water vapor calculated in the first process.

[0012] When the amount of moisture in the air outside the working device exceeds the amount of saturated water vapor at which condensation occurs on an object inside the working device, condensation occurs inside the working device. According to the above-described working device, it is possible to determine whether condensation will occur within the working device by determining whether the amount of moisture in the air outside the working device exceeds the amount of saturated water vapor at which condensation will occur on an object within the working device.

[0013] (3) In the first determination process, the control unit may determine that condensation will occur inside the working apparatus when a temperature of an object inside the working apparatus has decreased.

[0014] When the temperature of the object inside the working device drops, condensation occurs inside the working device. According to the above-described working device, it is possible to determine whether condensation will occur inside the working device by determining whether the temperature of the object inside the working device has decreased.

[0015] (4) The working device may have a fan that draws in air outside the working device, and the control unit may execute a stop process to stop the fan when it is determined by the first determination process that condensation will occur.

[0016] According to the above-described working device, when it is determined that condensation will occur, the fan is stopped, so that humid air outside the working device is less likely to flow into the working device, thereby suppressing condensation inside the working device.

[0017] (5) An air conditioning setting device according to the present disclosure is an air conditioning setting device that is installed in a factory having air conditioning equipment and is communicatively connected to one or more work devices that perform specified work, and is equipped with a second communication unit that communicates with the work devices, a third communication unit that communicates with the air conditioning equipment, and a control unit, wherein the control unit executes a first reception process of receiving information from each of the work devices via the second communication unit for determining whether condensation will occur in the work device, a second determination process of determining whether condensation will occur in any of the work devices based on the information received in the first reception process, and a second change process of changing the settings of the air conditioning equipment via the third communication unit so as to suppress condensation in the work device where it is determined that condensation will occur if the second determination process determines that condensation will occur in any of the work devices.

[0018] According to the above air conditioning setting device, if condensation occurs in any of the working devices, the settings of the air conditioning equipment are changed to suppress condensation in the working device determined to have condensation, so that condensation can be suppressed in the working devices without providing a temperature control means or a humidity control means in the working devices. Therefore, the above air conditioning setting device can suppress condensation in the working devices with a simple configuration.

[0019] (6) A maintenance device group according to the present disclosure is a maintenance device group consisting of a plurality of maintenance devices installed in a factory having air conditioning equipment and each performing a predetermined task, wherein one of the maintenance devices is set as a master device and the other maintenance devices are set as slave devices, and the master device is equipped with a fourth communication unit that communicates with the slave devices, a fifth communication unit that communicates with the air conditioning equipment, and a control unit, and the master device executes a third determination process of determining whether condensation will occur in the master device based on the temperature and humidity inside and outside the master device, a second reception process of receiving information from each of the slave devices via the fourth communication unit for determining whether condensation will occur in the slave device, a fourth determination process of determining whether condensation will occur in any of the slave devices based on the information received in the second reception process, and a third change process of changing a setting of the air conditioning equipment via the fifth communication unit so as to suppress condensation in the maintenance device where it is determined that condensation will occur, when it is determined that condensation will occur in the maintenance device in at least one of the third determination process and the fourth determination process.

[0020] According to the above-mentioned group of working devices, if condensation occurs in any of the working devices, the settings of the air conditioning equipment are changed to suppress condensation in the working device in question, so that condensation in the working device can be suppressed without providing a temperature control means or a humidity control means in the working device. Therefore, according to the above-mentioned group of working devices, condensation in the working devices can be suppressed with a simple configuration. Furthermore, with the above-mentioned maintenance device group, one of the maintenance devices acts as a master device (in other words, an air conditioning setting device), so there is no need to prepare an air conditioning setting device separately from the maintenance devices, which makes it possible to further simplify the configuration for suppressing condensation inside the maintenance devices.

[0021] (7) It may be possible to change which of the plurality of maintenance devices is to be the master device by a setting.

[0022] The above-described group of work devices allows greater freedom in selecting which work device to set as the master device. For example, if a work device set as the master device is removed, another work device can operate as the master device.

[0023] (8) A plurality of lines in which a plurality of the work devices are lined up in a row may be arranged in parallel, and one of the work devices for each line may be set as the master device, and it may be possible to change which of the master devices on which line changes the settings of the air conditioning equipment by changing the settings.

[0024] The positional relationship between the line and the air conditioning equipment varies depending on the factory. With the above-mentioned group of operation devices, it is possible to set which of the line's master devices will change the settings of the air conditioning equipment depending on the positional relationship between the line and the air conditioning equipment.

[0025] (9) The work device disclosed herein is a work device installed in a factory having air conditioning equipment to perform specified work, and is equipped with a sixth communication unit that communicates with other devices, and a control unit, and the control unit executes a fifth determination process that determines whether condensation will occur within the work device based on the temperature and humidity inside and outside the work device, and a transmission process that transmits the determination result of the fifth determination process to other devices via the sixth communication unit.

[0026] For example, a maintenance device can transmit information such as temperature and humidity inside and outside the maintenance device to an air conditioning setting device, and the air conditioning setting device can use that information to determine whether condensation will occur inside the maintenance device. In that case, however, the air conditioning setting device must individually use that information to determine whether condensation will occur for each of the multiple maintenance devices, which increases the processing load on the air conditioning setting device. According to the above-mentioned maintenance devices, each maintenance device determines for itself whether or not condensation will occur within the maintenance device and transmits the determination result to the air conditioning setting device, so that the processing load on the air conditioning setting device can be reduced.

[0027] [Details of the embodiment of the present disclosure] The present disclosure will be described below with reference to the embodiments. The present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. The embodiments of the present disclosure can be realized in various forms, such as an apparatus, a method, a computer program for implementing the functions of these apparatuses or methods, and a recording medium on which the computer program is recorded.

[0028] <Embodiment 1> The first embodiment will be described with reference to Figures 1 to 8. In the following description, the reference numerals of the drawings may be omitted for the same components, with some exceptions.

[0029] (1) Factory A factory 1 according to the first embodiment will be described with reference to Fig. 1. The factory 1 is a factory where components are mounted on circuit boards. Within the factory 1, there are arranged a production line 10 (an example of a line or group of work devices) for mounting components on circuit boards, air conditioning equipment 11 for adjusting the temperature and humidity within the factory 1, a temperature sensor 12 for detecting the temperature within the factory 1, a humidity sensor 13 for detecting the humidity within the factory 1, and the like, which are communicatively connected via a communication network 14. For ease of understanding, in the first embodiment, it is assumed that there is only one production line 10.

[0030] (2) Production line 1, the production line 10 is equipped with a plurality of operating devices 20 (a loader 20A, a screen printer 20B, a print inspection machine 20C, a dispenser 20D, three surface mounters 20E, a post-mounting appearance inspection machine 20F, a reflow machine 20G, a post-cure appearance inspection machine 20H, and an unloader 20I), which are arranged in a row via a plurality of conveyors 20J. The conveyor 20J is also one of the operating devices 20.

[0031] 2, a description will be given of an electrical configuration common to each operating device 20. The operating device 20 includes a control unit 30, a memory unit 31, a operating unit 32, a communication unit 33 (an example of a first communication unit, a second communication unit, a third communication unit, a fourth communication unit, a fifth communication unit, and a sixth communication unit), a temperature sensor 34, a humidity sensor 35, a cooling fan 36 (an example of a fan), an operation unit 37, and the like.

[0032] The control unit 30 includes a CPU 30A, a RAM 30B, etc. Various programs and data executed by the control unit 30 are stored in the memory unit 31. The configuration of the working unit 32 differs depending on the working device 20. For example, the working unit 32 of the screen printer 20B performs the task of printing a circuit pattern on a board using a mask. The working unit 32 of the surface mounter 20E performs the task of mounting components on a board on which a circuit pattern has been printed.

[0033] The communication unit 33 is a communication circuit for connecting the maintenance apparatus 20 to the communication network 14. The control unit 30 is capable of communicating with other maintenance apparatuses 20 and air conditioning equipment 11 via the communication unit 33. The communication unit 33 is an example of a fourth communication unit for communicating with other maintenance apparatuses 20 and a fifth communication unit for communicating with the air conditioning equipment 11. That is, in the first embodiment, the communication unit 33 serves as both the fourth communication unit and the fifth communication unit. The fourth communication unit and the fifth communication unit may be configured as separate communication units.

[0034] The temperature sensor 34 is a sensor that detects the temperature of a condensation measurement object 40 (an example of an object) described below inside the working apparatus 20. The humidity sensor 35 is a sensor that detects the humidity inside the working apparatus 20. The cooling fan 36 is a fan that cools the inside of the working apparatus 20 by sucking air outside the working apparatus 20 into the working apparatus 20. The operation unit 37 is made up of input devices such as a keyboard, mouse, touch panel, and various operation buttons, and output devices such as an LCD display.

[0035] (3) Changing air conditioning equipment settings As shown in FIG. 3, in the first embodiment, one of the multiple operating devices 20 constituting the production line 10 is set as a master device, and the other operating devices 20 are set as slave devices. The master device can also be called an air conditioning setting device. Any operating device 20 can become the master device. Which operating device 20 is the master device can be changed by settings. This setting can be made, for example, by an operator in the factory 1 operating the operation unit 37 of the operating device 20. For the slave devices, the master device is an example of another device.

[0036] While the master device and the slave device are powered on, they repeatedly determine whether condensation will occur in the working device 20. The determination of whether condensation will occur will be described later. Each slave device transmits its determination result (one example of information for determining whether condensation will occur in the slave device) to the master device. When the master device determines that condensation will occur in at least one of the multiple working devices 20 including the master device, the master device changes the settings of the air conditioning equipment 11 so as to suppress condensation in the working device 20 determined to cause condensation. A specific description will be given below.

[0037] (3-1) Determine whether condensation will occur The control unit 30 of each working device 20 repeatedly determines whether or not the following condition A or condition B is met while the power is on, and determines that condensation will occur if at least one of the conditions is met. 4 and 5 is a heat sink or sheet metal inside the working device 20. The condensation measurement object 40 is not limited to these, and may be, for example, a circuit board of the working device 20. The saturated water vapor amount of the condensation measurement object 40 described below is the amount of water vapor at which condensation occurs on the condensation measurement object 40. The saturated water vapor amount varies depending on the temperature of the condensation measurement object 40. It is assumed that the saturated water vapor amount for each temperature is measured in advance by experiment and stored in the memory unit 31.

[0038] (Condition A) When the amount of moisture in the air that exceeds the saturated water vapor amount of the object being measured for condensation is detected outside the work device 4 shows the state of a certain operating device 20 at a certain point in time. In the example shown in FIG. 4, the temperature of the condensation measurement object 40 (the temperature detected by the temperature sensor 34) is 30° C. The amount of saturated water vapor in the condensation measurement object 40 when the temperature is 30° C. is 24.12 g / m 3 The temperature outside the working apparatus 20 (the temperature detected by the temperature sensor 12) is 35° C., and the humidity outside the working apparatus 20 (the humidity detected by the humidity sensor 13) is 85%. In this case, the amount of moisture in the air outside the working apparatus 20 is calculated to be 25.96 g / m from the temperature and humidity outside the working apparatus 20. 3 In this case, the amount of moisture in the air outside the working device 20 (= 25.96 g / m 3 ) is the saturated water vapor amount (= 24.12 g / m 3 ), the control unit 30 determines that condensation will occur on the condensation measurement object 40.

[0039] (Condition B) When the temperature of the object being measured for condensation drops 5 shows the amount of saturated water vapor in the condensation measurement object 40, the temperature and humidity in the working device 20, and the amount of moisture in the air in the working device 20 when the temperature of the condensation measurement object 40 is 30° C. and 29° C. The amount of saturated water vapor when the temperature of the condensation measurement object 40 is 30° C. is 24.12 g / m 3 The temperature inside the working device 20 is 35° C., the humidity inside the working device 20 is 77%, and the amount of moisture in the air inside the working device 20 is 23.51 g / m 3 When the temperature of the condensation measurement object 40 is 30° C., the amount of moisture in the air inside the working device 20 (= 23.51 g / m 3 ) is the saturated water vapor amount (=24.12g / m 3 ) does not exceed this temperature, so condensation does not occur.

[0040] In contrast, when the temperature of the condensation measurement object 40 is 29°C, the amount of saturated water vapor is 22.98g / m 3It is assumed that the temperature, humidity, and amount of moisture in the air inside the working device 20 when the temperature of the condensation measurement object 40 is 29° C. are the same as when it is 30° C. In this case, the amount of moisture in the air inside the working device 20 (=23.51 g / m) has decreased due to the decrease in the amount of saturated water vapor in the condensation measurement object 40. 3 ) is the saturated water vapor amount (=22.98g / m 3 ) is exceeded. Therefore, the control unit 30 determines that condensation will occur on the condensation measurement object 40 if the temperature of the condensation measurement object 40 drops.

[0041] (3-2) Changing the settings of air conditioning equipment When it is determined that condensation will occur in at least one of the multiple work devices 20 including the master device, the control unit 30 of the master device acquires the temperature and humidity of the work device 20 determined to have condensation, and changes the settings of the air conditioning equipment 11 based on the acquired temperature and humidity.

[0042] 6 shows a case where condition A is satisfied for a certain working device 20 when the set temperature of the air conditioning equipment 11 is 35° C. and the set humidity is 85%. In the example shown in FIG. 6, when the set temperature is 35° C. and the set humidity is 85%, the temperature of the condensation measurement object 40 is 30° C. and the saturated water vapor amount of the condensation measurement object 40 is 24.12 g / m 3 , the temperature outside the working device 20 is 35° C., the humidity outside the working device 20 is 85%, and the amount of moisture in the air outside the working device 20 is 25.96 g / m 3 Let's say it was.

[0043] In order to suppress condensation on a certain working apparatus 20, the control unit 30 of the master device changes the settings of the air conditioning equipment 11 based on the temperature and humidity of the certain working apparatus 20 so as to suppress condensation on the certain working apparatus 20. Specifically, for example, as shown in Fig. 6, the control unit 30 of the master device changes the set temperature of the air conditioning equipment 11 to 30°C and the set humidity to 80%. 30°C and 80% are merely examples, and the changes may be other than 30°C and 80% as long as they suppress condensation.

[0044] 6, when the set temperature of the air conditioning equipment 11 is changed to 30°C and the set humidity to 80%, the temperature outside the working apparatus 20 drops to 30°C and the humidity drops to 80%. As a result, the moisture content in the air outside the working apparatus 20 drops to 19.29%. Therefore, the moisture content in the air outside the working apparatus 20 is lower than the saturated water vapor content of the condensation measurement object 40 of that particular working apparatus 20, and condensation is suppressed.

[0045] (4) Processing performed by the work device As the processes executed by the maintenance device 20, a "process for determining whether condensation will occur" executed by the master device and the slave device, and a "process for changing the settings of the air conditioning equipment 11" executed by the master device will be described.

[0046] (4-1) Process to determine whether condensation will occur The "process of determining whether condensation will occur" will be described with reference to Fig. 7. This process is repeatedly executed while the working device 20 is powered on. This process executed by the master device is an example of the third determination process, and this process executed by the slave device is an example of the fifth determination process.

[0047] In S101, the control unit 30 judges whether or not the condition A is satisfied. Specifically, the control unit 30 executes a process (an example of a first process) of determining the amount of saturated water vapor at which condensation occurs on the condensation measurement object 40 based on the temperature of the condensation measurement object 40 inside the working apparatus 20, and a process (an example of a second process) of determining the amount of moisture in the air outside the working apparatus 20 based on the temperature and humidity outside the working apparatus 20, and judges that the condition A is satisfied if the amount of moisture in the air exceeds the amount of saturated water vapor. If the condition A is satisfied, the control unit 30 proceeds to S103, and if it is not satisfied, the control unit 30 proceeds to S102.

[0048] In S102, the control unit 30 determines whether or not the condition B is satisfied. Specifically, the control unit 30 determines whether or not the temperature of the condensation measurement object 40 in the working device 20 has dropped, and if the temperature has dropped, it determines that the condition B is satisfied. If the condition B is satisfied, the control unit 30 proceeds to S103, and if not, it proceeds to S104.

[0049] S103 and S104 described below are executed when the maintenance apparatus 20 executing this process is a slave apparatus. When the maintenance apparatus 20 executing this process is a master apparatus, S103 and S104 are omitted.

[0050] In S103, the control unit 30 transmits a determination result indicating that condensation will occur to the master device (an example of a transmission process). The process in which the master device receives the determination result is an example of a second reception process. In S104, the control unit 30 transmits a determination result indicating that condensation will not occur to the master device (an example of a transmission process). The process in which the master device receives the determination result is an example of a second reception process.

[0051] (4-2) Changing the settings of air conditioning equipment The "processing for changing the settings of the air conditioning equipment 11" will be described with reference to Fig. 8. This process is an example of the third change process. This process is started when the master device receives the above-mentioned determination results from each slave device.

[0052] In S201, the control unit 30 determines whether or not condensation will occur in at least one of the multiple maintenance apparatuses 20 including the master apparatus, based on the determination result of the master apparatus itself and the determination results received from each slave apparatus (an example of a fourth determination process). If condensation will occur in at least one maintenance apparatus 20, the control unit 30 proceeds to S202, and if condensation will not occur, the control unit 30 returns to S201 and repeats the process.

[0053] In S202, the control unit 30 commands the maintenance device 20 that has determined that condensation will occur to stop the cooling fan 36 (an example of a stop process). When the maintenance device 20 that has determined that condensation will occur receives the command to stop the cooling fan 36, it stops the cooling fan 36. When the maintenance device 20 that has determined that condensation will occur may stop the cooling fan 36 without receiving a command from the master device.

[0054] In S203, the control unit 30 receives the temperature of the condensation measurement object 40 of the working device 20 and the humidity within the working device 20 from the working device 20 that has been determined to cause condensation, and determines the set temperature and set humidity of the air conditioning equipment 11 from the received temperature and humidity so as to suppress condensation within the working device 20. In S204, the control unit 30 communicates with the air conditioning equipment 11 and changes the set temperature and set humidity of the air conditioning equipment 11 to the set temperature and set humidity determined in S203 (an example of a third change process).

[0055] In S205, the control unit 30 determines whether the temperature and humidity outside the working device 20 have reached the set temperature and humidity, and if so, proceeds to S206, and if not, executes S205 again after a predetermined time has elapsed. In S206, the control unit 30 instructs the working device 20, which has been determined to have condensation, to rotate the cooling fan 36. After instructing the cooling fan 36 to rotate, the control unit 30 returns to S201 and repeats the process.

[0056] (5) Effects of the embodiment According to the production line 10 of the first embodiment, when condensation occurs in any of the operating devices 20, the settings of the air conditioning equipment 11 are changed to suppress condensation in the operating device 20 where condensation occurs, so that condensation in the operating device 20 can be suppressed without providing a temperature control means or a humidity control means in the operating device 20. Therefore, according to the production line 10, condensation in the operating device 20 can be suppressed with a simple configuration. In other words, damage to the circuit board in the operating device 20 due to condensation can be suppressed with a simple configuration. Furthermore, according to the production line 10, one of the multiple operating devices 20 operates as a master device (in other words, an air conditioning setting device), so there is no need to prepare an air conditioning setting device in addition to the operating device 20. This makes it possible to further simplify the configuration for suppressing condensation inside the operating device 20.

[0057] According to the production line 10, it is possible to determine whether condensation will occur within the working device 20 by determining whether the amount of moisture in the air outside the working device 20 exceeds the amount of saturated water vapor at which condensation will occur on the condensation measurement object 40 within the working device 20.

[0058] According to the production line 10, by determining whether the temperature inside the operating device 20 has decreased, it is possible to determine whether condensation will occur inside the operating device 20.

[0059] According to the production line 10, which of the multiple operating apparatuses 20 is to be the master apparatus can be changed by settings, improving the degree of freedom in selecting which operating apparatus 20 is to be the master apparatus. For example, when an operating apparatus 20 set as the master apparatus is removed, another operating apparatus 20 can operate as the master apparatus.

[0060] According to the production line 10, when condensation occurs in any of the operating devices 20, the cooling fan 36 of the operating device 20 where the condensation occurs is stopped, so that it becomes difficult for humid air outside the operating device 20 to flow into the operating device 20. Therefore, condensation in the operating device 20 can be suppressed.

[0061] Here, it is also effective to take measures against condensation, such as applying moisture-proof coating to each part inside the operating device 20, making the operating device 20 fanless, and adding wind-blocking metal plates. However, taking these measures against condensation increases the manufacturing cost of the operating device 20. With the production line 10, condensation can be suppressed without taking these measures against condensation, so there is also the advantage that the manufacturing cost of the operating device 20 can be suppressed. Furthermore, according to the production line 10, the master device automatically changes the settings of the air conditioning equipment 11, which has the advantage of reducing the number of workers required compared to when an operator changes the settings, and the advantage of suppressing condensation, which improves the manufacturing quality of the boards produced by the production line 10. In addition, according to the production line 10, the operating device 20 repeatedly determines whether condensation is occurring, which has the advantage of allowing early detection of the occurrence of condensation.

[0062] According to the maintenance device 20 of the first embodiment, each maintenance device 20 judges for itself whether or not condensation will occur within the maintenance device 20 and transmits the judgment result to the master device, so that the processing load of the master device can be reduced.

[0063] <Embodiment 2> In the above-described embodiment 1, an example has been described in which there is only one production line 10. In contrast, as shown in Fig. 9, in embodiment 2, there are multiple production lines 10, and the air outlets of the air conditioning equipment 11 are arranged across adjacent production lines 10 in a top view. The air outlets of the air conditioning equipment 11 may be located between adjacent production lines 10.

[0064] 9, there are three lines: production line 10A, production line 10B, and production line 10C. In top view, the air outlet of the air conditioning equipment 11A spans the production lines 10A and 10B, and the air outlet of the air conditioning equipment 11B spans the production lines 10B and 10C.

[0065] When there are multiple production lines 10 and the air conditioning equipment 11 outlets are arranged across adjacent production lines 10, it is possible to change which production line 10's master device changes the settings of the air conditioning equipment 11 by setting it. This setting can be performed, for example, by an operator of the factory 1 operating the operation unit 37 of the working device 20.

[0066] For example, if the distance from production line 10A to the air outlet of air conditioning equipment 11A is different from the distance from production line 10B to the air outlet of air conditioning equipment 11A, the operator may set the master device of production line 10 closer to the air outlet of air conditioning equipment 11A to change the settings of air conditioning equipment 11A.

[0067] Alternatively, if the distance from production line 10A to the air outlet of air conditioning equipment 11A and the distance from production line 10B to the air outlet of air conditioning equipment 11A are approximately the same, the operator may set the master device of any of the production lines 10 to change the settings of the air conditioning equipment 11A.

[0068] Alternatively, the operator may set which of the production lines 10's master devices will change the settings of the air conditioning equipment 11, taking into consideration the frequency of condensation occurrence. For example, even if the production line 10A is closer to the air outlet of the air conditioning equipment 11A than the production line 10B, if the production line 10B has a higher frequency of condensation occurrence (for example, if the operation equipment 20 constituting the production line 10B has been determined to have condensation occur more frequently in the past than the operation equipment 20 constituting the production line 10A), the operator may set the master device of the production line 10B to change the settings of the air conditioning equipment 11A.

[0069] According to the production line 10 of embodiment 2, when there are multiple production lines 10, an operator can set which production line 10's master device will change the settings of the air conditioning equipment 11, depending on the positional relationship between the production line 10 and the air outlet of the air conditioning equipment 11, etc.

[0070] <Embodiment 3> In the above-described first and second embodiments, the air conditioning equipment 11 is connected to the communication network 14, and the control unit 30 of the master device changes the settings of the air conditioning equipment 11 via the communication unit 33. In the first and second embodiments, any of the operation devices 20 can communicate with the air conditioning equipment 11, and therefore any of the operation devices 20 can become a master device.

[0071] In contrast, the air conditioning equipment 11 does not have to be connected to the communication network 14. In this case, as shown in Fig. 10, the master device may be provided with a wireless communication unit 50 (an example of a fifth communication unit) for wirelessly communicating with the air conditioning equipment 11, and the master device may change the settings of the air conditioning equipment 11 via the wireless communication unit 50. In this case, only the maintenance device 20 equipped with the wireless communication unit 50 can become the master device.

[0072] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included in the technical scope disclosed in this specification.

[0073] (1) In the above embodiment 1, a case has been described in which each slave device determines whether or not condensation will occur within the slave device based on the temperature and humidity inside and outside the slave device, and transmits the determination result to the master device. However, each slave device may transmit information about the temperature and humidity inside the slave device, and the master device may determine whether or not condensation will occur within the slave device based on that information.

[0074] (2) In the above embodiment 1, when condensation occurs in any of the working apparatuses 20, the cooling fan 36 of the working apparatus 20 in which condensation occurs is stopped. In contrast, the cooling fan 36 may be stopped only when condition A (when an amount of moisture in the air exceeding the amount of saturated water vapor in the condensation measurement object 40 is detected outside the working apparatus 20) is met. When condition A is met, the amount of moisture in the air outside the working apparatus 20 is high, so stopping the cooling fan 36 can prevent air outside the working apparatus 20 with a high amount of moisture in the air from flowing into the working apparatus 20.

[0075] On the other hand, when condition B (when the temperature of the condensation measurement object 40 has dropped) is met, the amount of moisture in the air outside the working apparatus 20 does not necessarily exceed the amount of saturated water vapor in the condensation measurement object 40, so the cooling fan 36 may be left rotating. If the cooling fan 36 is left rotating, when the amount of moisture in the air outside the working apparatus 20 does not exceed the amount of saturated water vapor in the condensation measurement object 40, the humidity inside the working apparatus 20 will drop, which may suppress the occurrence of condensation.

[0076] (3) In the above embodiment 1, the case where the temperature of the condensation measurement object 40 drops is described as an example of condition B, but condition B is not limited to this. For example, condition B may be that an amount of moisture in the air that exceeds the amount of saturated water vapor of the condensation measurement object 40 is detected in the working device 20.

[0077] (4) In the above embodiment 1, an example has been described in which the temperature sensor 12 that detects the temperature within the factory 1 and the humidity sensor 13 that detects the humidity within the factory 1 are connected to the communications network 14, but these sensors may be directly connected to any of the maintenance apparatuses 20. The other maintenance apparatuses 20 may obtain the temperature and humidity outside the maintenance apparatus 20 via the communications network 14 from the maintenance apparatuses 20 to which these sensors are connected.

[0078] (5) In the above embodiment 1, no sprayer (or humidifier) ​​that sprays water in mist form is installed in the factory 1, but a sprayer may be installed in the factory 1. If the master device determines that condensation will occur in any of the working devices 20, it may stop the sprayer to suppress an increase in humidity (or change the setting to reduce the amount of spray from the sprayer). In this case, the sprayer is an example of air conditioning equipment.

[0079] (6) In the above embodiment 1, the air conditioning equipment 11 is described as being capable of adjusting both temperature and humidity. However, the air conditioning equipment 11 may be capable of adjusting only temperature or only humidity.

[0080] (7) In the above embodiment 1, an example has been described in which a plurality of operating apparatuses 20 are installed in the factory 1. In contrast, if only one operating apparatus 20 is installed in the factory 1, or if there are multiple operating apparatuses 20 but only one operating apparatus 20 requires suppression of condensation, that operating apparatus 20 itself may change the settings of the air conditioning equipment 11. Alternatively, if there are multiple operating apparatuses 20, each operating apparatus 20 may change the settings of the air conditioning equipment 11 individually.

[0081] Specifically, the working device 20 (hereinafter referred to as the working device 20) includes a communication unit 33 (an example of a first communication unit) that communicates with the air conditioning equipment 11, and a control unit 30, and the control unit 30 may execute a first judgment process (corresponding to the third judgment process in embodiment 1) that judges whether condensation will occur within the working device 20 based on the temperature and humidity inside and outside the working device 20, and a first change process (corresponding to the third change process in embodiment 1) that changes the settings of the air conditioning equipment 11 via the communication unit 33 so as to suppress condensation within the working device 20 when it is determined by the first judgment process that condensation will occur.

[0082] According to the operating device 20, when it is determined that condensation will occur within the operating device 20, the settings of the air conditioning equipment 11 in the factory 1 are changed so as to suppress condensation within the operating device 20, so that the occurrence of condensation can be suppressed without providing the operating device 20 with a temperature control means or a humidity control means. Therefore, according to the operating device 20, condensation within the operating device 20 can be suppressed with a simple configuration.

[0083] (8) In the above embodiment 1, an example was described in which one of the maintenance devices 20 also served as a master device (in other words, an air conditioning setting device). In contrast, the air conditioning setting device may be, for example, a personal computer (an example of a computer) connected to the communications network 14. In other words, an air conditioning setting device may be prepared separately from the maintenance device 20.

[0084] Specifically, the air conditioning setting device includes a communication unit 33 (an example of a second communication unit) that communicates with the maintenance device 20, a communication unit 33 (an example of a third communication unit) that communicates with the air conditioning equipment 11, and a control unit 30. The control unit 30 may execute a first reception process (corresponding to the second reception process in embodiment 1) of receiving information for determining whether condensation will occur in each maintenance device 20 via the communication unit 33, a second judgment process (corresponding to S201 in embodiment 1) of determining whether condensation will occur in any of the maintenance devices 20 based on the information received in the first reception process, and a second change process (corresponding to the third change process in embodiment 1) of changing the settings of the air conditioning equipment 11 via the communication unit 33 so as to suppress condensation in the maintenance device 20 where it is determined that condensation will occur, if the second judgment process determines that condensation will occur in any of the maintenance devices 20.

[0085] According to this air conditioning setting device, when condensation occurs in any of the working devices 20, the settings of the air conditioning equipment 11 are changed to suppress condensation in the working device 20 determined to cause condensation, so that it is possible to suppress condensation from occurring in the working device 20 without providing a temperature control means or a humidity control means in the working device 20. Therefore, according to this air conditioning setting device, condensation in the working device 20 can be suppressed with a simple configuration. [Explanation of symbols]
