Description

  The present invention relates to a lighting control system that controls a plurality of lighting fixtures on a floor on which a plurality of production apparatuses are installed.

  As equipment for producing a substrate on which a large number of components are mounted, there are a solder printer, an electronic component mounting machine, a reflow machine, a board inspection machine, and the like. It is common to configure a substrate production line by connecting these substrate production facilities. In addition, there are many substrate production factories where a plurality of substrate production lines are installed on one floor. In recent years, automation and labor saving of the board production line have been promoted, and the number of operators on the floor of the board production factory is decreasing. For this reason, when a factor that requires work occurs in any of the board production facilities, measures are taken such as sending a call signal to the portable terminal held by the operator or using a notification lamp or a buzzer. Yes.

  On the other hand, on the floor, lighting is generally turned on for work regardless of day or night. In this case, with the progress of automation, a time zone in which a lot of power for lighting is consumed unnecessarily even though there is no operator in the floor increases, which is not preferable in terms of energy management. In the smart factory concept proposed in recent years, it is important to save energy by lighting only the places where operators are located, in other words, the places necessary for work. On the other hand, if the light is turned off even though the operator is working, workability deteriorates. For example, in a conventional system that automatically controls illumination according to the detection result of the human sensor, the operator's movement may stop and the light may turn off automatically after a certain period of time. One technical example of an illumination control system that achieves this type of energy saving is disclosed in Patent Document 1.

  The factory lighting system of Patent Document 1 is a base lighting fixture that secures the base illuminance of a factory that houses a large number of automatic machines, a local lighting fixture that secures the working illuminance of each automatic machine, and lighting control of the local lighting fixtures. And a controller for remotely operating the controller. Furthermore, the aspect of the operation device mounted in each automatic machine and the aspect of the portable operation device which can be carried are disclosed. According to this, when an inspection / repair work or the like by an operator is required, the illuminance for work can be ensured by turning on the minimum necessary lighting fixtures, and the power saving effect is obtained.

JP-A-6-275383

  By the way, in the technical example of patent document 1, since a local lighting fixture is lighted only to the automatic machine with which the factor which requires work generate | occur | produced, the point which the effect of a power saving (energy saving effect) produces is preferable. However, when a factor that requires work occurs on the board production line, the work is rarely completed only by the board production apparatus that caused the work.

  For example, a substrate defect found by inspection performed by the substrate appearance inspection apparatus is one factor that requires operator investigation and maintenance work. At this time, the operator can grasp the occurrence state of the defect by investigating the substrate appearance inspection apparatus. However, in many cases, it is also necessary to investigate the board production apparatus on the upstream side of the line in order to investigate the cause of the defect and take measures to resume operation. Then, the operator goes back and forth on the board production line, and it is not sufficient to only illuminate the board appearance inspection apparatus. In other words, when the entire board production line including the board appearance inspection apparatus is automatically illuminated, workability is improved.

  In addition, for example, the lack of parts in the electronic component mounting machine is one factor that requires the operator's replenishment work. At this time, it is necessary for the operator to move to the component storage place in order to take out the tape reel or feeder device holding a large number of electronic components. Then, it is not sufficient to illuminate the electronic component mounting machine alone. When the parts storage and the movement path are automatically illuminated, it is convenient to move, and workability is improved. As can be seen from these two examples, even if only the device in which the factor has occurred is illuminated, the workability may be reduced.

  Furthermore, in the conventional system that automatically controls the illumination according to the detection result of the human sensor, there is a risk that even if there is an operator on the floor, the light is automatically turned off. Therefore, there is a need for a system in which the operator does not turn off until the factor is eliminated through work and is extinguished after the factor is eliminated.

  The risk of workability degradation and the risk of automatic turn-off when an operator is present are not limited to lighting fixtures in a board production factory. In other words, the fear described above is a common problem when saving energy with a plurality of lighting fixtures on a floor where a plurality of production apparatuses related to various products are installed.

  The present invention has been made in view of the problems of the background art described above, and when a factor requiring an operation by an operator occurs in any of a plurality of production apparatuses, a related location is added in addition to the location where the factor is generated. It is an issue to be solved to provide an illumination control system that can achieve both energy saving effect and good workability by selecting and illuminating.

  An illumination control system of the present invention that solves the above problems is an illumination control system that controls a plurality of production apparatuses and a plurality of illumination fixtures that illuminate and share at least one of the floors on which the plurality of production apparatuses are installed. A call signal acquisition unit that acquires a call signal generated in the first production device when a factor that requires an operation by an operator occurs in the first production device among the plurality of production devices; and the call signal When the call signal is generated, the energy saving maintenance unit that maintains the plurality of lighting fixtures in an extinguished state or an energy saving lighting state that saves lighting power in the entire floor, A factor location lighting unit for lighting a lighting fixture that shares at least one of a first production device and a floor area around the first production device, and the call signal A related location corresponding to at least one of a production device other than the first production device and a floor area away from the first production device, and the operator may move for the work. And a related part lighting unit that variably selects and lights a lighting fixture that shares a certain related part based on the contents of the factor.

  In the lighting control system of the present invention, while the call signal is not generated, the energy saving maintaining unit functions to generate an energy saving effect. When the call signal is generated, the factor location lighting unit automatically illuminates the factor occurrence location, and the related location lighting unit automatically illuminates the related location. That is, the place where the operator performs work and the place where there is a possibility of moving are automatically illuminated, so that workability is improved and the work target place is easy to understand. Therefore, the lighting control system of the present invention can achieve both an energy saving effect and good workability.

(1. Configuration of the illumination control system 1 of the first embodiment)
A lighting control system 1 according to a first embodiment of the present invention will be described with reference to FIGS. The lighting control system 1 according to the first embodiment controls turning on and off of a plurality of lighting fixtures on the floor 91 of the board production factory. FIG. 1 is a plan view showing the arrangement of substrate production apparatuses and lighting fixtures on a floor 91 of a substrate production factory. FIG. 2 is a configuration diagram illustrating a configuration of the illumination control system 1 according to the first embodiment. In FIG. 2, a side view of the first substrate production line 81 is shown as a representative, and the second to fifth substrate production lines 82 to 85 having the same configuration are not shown.

  As shown in FIG. 1, five lines of first to fifth substrate production lines 81 to 85 are installed at approximately equal intervals in parallel with the short side 97 of the rectangular floor 91. A passage is secured between the first to fifth substrate production lines 81 to 85. A passage is also secured between the peripheral wall of the floor 91 and the first to fifth substrate production lines 81 to 85. A main entrance 92 is provided at a position between the second substrate production line 82 and the third substrate production line 83 on one long side 98 of the floor 91. A sub-entrance 93 is provided at a position between the second substrate production line 82 and the third substrate production line 83 on the other long side 99 of the floor 91. The auxiliary doorway 93 communicates with the component member chamber 95.

  The line configurations of the first to fifth substrate production lines 81 to 85 and the arrangement of the lighting fixtures are similar, and the first substrate production line 81 will be described as an example. The first substrate production line 81 includes six substrate production apparatuses (71 to 76) arranged in a line. That is, from the other long side 99 side of the floor 91 to the one long side 98 side, the solder printer 71, the print inspection machine 72, the first electronic component mounting machine 73, the second electronic component mounting machine 74, the board appearance inspection. The machine 75 and the reflow machine 76 are lined up. The line configuration may be other than those described above, and the line configurations of the first to fifth substrate production lines 81 to 85 may be different from each other. Further, near the wall of the other long side 99 of the floor 91, first to fifth component storage areas 981 to 985 are provided in the vicinity of the first to fifth substrate production lines 81 to 85, respectively.

  In preparation for a setup change operation for changing the types of substrates produced in the first to fifth substrate production lines 81 to 85, a component supply device including a plurality of feeder devices is stored in a component member chamber 95 together with a transport carriage. In the component member chamber 95, various materials, components, tools, inspection tools, and the like are stored in addition to the component supply device.

  In preparation for replenishment work when the solder used in the solder printer 71 is insufficient, replenishment solder is placed in the first to fifth component storage areas 981 to 985. In preparation for replenishment work when the electronic components used in the first electronic component mounting machine 73 and the second electronic component mounting machine 74 run out, tape reels or feeder devices holding a large number of electronic components for replenishment are first to first. It is placed in the fifth parts storage 981 to 985.

  Further, a spare squeegee is placed in the first to fifth component storage areas 981 to 985 in preparation for replacement work when the squeegee used in the solder printer 71 is replaced. In preparation for replacement work when the mounting nozzles used in the first electronic component mounting machine 73 and the second electronic component mounting machine 74 are replaced, spare mounting nozzles are placed in the first to fifth component storage areas 981 to 985. The squeegee and the mounting nozzle are examples of the replacement member of the present invention. The component member chamber 95 and the first to fifth component storage areas 981 to 985 are examples of the component member storage area of the present invention.

  Three first to third lighting fixtures 211 to 213 are arranged in a row on the ceiling above the first substrate production line 81. The first to third lighting fixtures 211 to 213 may be suspended from the ceiling so as to approach the first substrate production line 81. The 1st lighting fixture 211 divides and illuminates the solder printer 71, the printing inspection machine 72, the 1st components storage place 981, and the floor area around these. The 2nd lighting fixture 212 divides and illuminates the 1st electronic component mounting machine 73, the 2nd electronic component mounting machine 74, and the floor area around these. The 3rd lighting fixture 213 divides and illuminates the board | substrate visual inspection machine 75, the reflow machine 76, and the floor area around these.

  Further, the third lighting fixture 223 of the second board production line 82 and the third lighting fixture 233 of the third board production line 83 share the lighting of the floor area near the main entrance 92. The first lighting fixture 221 of the second board production line 82 and the first lighting fixture 231 of the third board production line 88 share the lighting of the floor area near the sub entrance / exit 93. The number of lighting fixtures is 3 for each of the board production lines 81 to 85, for a total of 15.

  In the above description, the lighting apparatus is shared for the board production apparatus (71 to 76) and the floor area to be illuminated. However, separate lighting apparatuses may be used for the apparatus illumination and the floor illumination. . Moreover, while providing a lighting fixture in a floor surface and illuminating a board | substrate production apparatus (71-76) from the downward direction, you may illuminate a channel | path from a side.

  In proximity to the first to third lighting fixtures 211, 212, and 213, first to third person detection sensors 311, 312, and 313 are provided downward, respectively. A total of 15 human detection sensors have a detection range indicated by a broken-line circle in FIG. 1 and detect an operator located in the floor 91. The human detection sensors 311 to 313 turn off the detection signal Md that is output when no operator is detected, and turn on the detection signal Md when the operator is detected. Thereby, lighting fixtures 211 to 213 arranged close to the human detection sensors 311 to 313 are individually controlled to be lighted (details will be described later). As a sensing method of the human sensor, a method of sensing human heat, a method of detecting a change in infrared reflection, or the like can be adopted.

  The first person detection sensor 311 of the first board production line 81 detects an operator who performs work with the solder printer 71 and the print inspection machine 72, and detects an operator standing in front of the first component storage place 981. The second person detection sensor 312 detects an operator who performs work on the first electronic component mounting machine 73 and the second electronic component mounting machine 74. The third person detection sensor 313 detects an operator who performs work with the board appearance inspection machine 75 and the reflow machine 76. Further, the first to third person detection sensors 311 to 313 also detect an operator who moves in a passage within the detection range.

  On the other hand, the illumination of the component member chamber 95 is shared by the dedicated indoor lighting device 26. No human sensor is provided in the component member chamber 95.

  A manually operated main illumination switch 37 is disposed on the wall near the main entrance 92. The main lighting switch 37 is composed of five line-by-line switches, and can turn on and off the three lighting fixtures in each of the board production lines 81 to 85 at once. When the main illumination switch 37 is turned on for each line, the operation signals M1 to M5 output for each line are turned on. A manually operated auxiliary illumination switch 38 is disposed on the wall in the vicinity of the auxiliary entrance 93. The auxiliary lighting switch 38 can turn on and off the indoor lighting device 26 in the component member chamber 95. When the sub illumination switch 38 is turned on, the operation signal M6 to be output is turned on.

  As shown in FIG. 2, the illumination control system 1 of the first embodiment includes 15 human detection sensors 311 to 313, an illumination control computer 4, and an illumination switchboard 5. The lighting control computer 4 has a CPU and operates by software. The lighting control computer 4 includes a display device and an input device (not shown) as an interface tool for exchanging information with an operator. The illumination control computer 4 also serves as a line management computer that manages the operation of the first to fifth substrate production lines 81 to 85.

  The lighting control computer 4 is connected to all the board production apparatuses (71 to 76) via the hub apparatus 47 and the local area network 48. The illumination control computer 4 acquires a contact signal regarding the operation status from each of the board production apparatuses (71 to 76). One type of contact signal is a call signal Sc. The call signal Sc is sent when a factor that requires work by the operator occurs in the substrate production apparatus (71 to 76). The lighting control computer 4 has a wireless transmitter and has a function of transmitting an operator call signal So to a portable terminal 49 possessed by the operator. The lighting control computer 4 is connected to a lighting switchboard 5.

  The lighting control computer 4 has functions of a call signal acquisition unit 41, an energy saving maintenance unit 42, a factor location lighting unit 43, and a related location lighting unit 44, and controls the lighting distribution board 5. The control operations of these units 41 to 44 will be described in detail later.

  The lighting switchboard 5 individually turns on and off the 15 lighting fixtures 211, 212, 213, 221, 223, 231, and 233 on the floor 91 and the interior lighting fixture 26 in the component member chamber 95. An AC power supply 51 is supplied to the lighting switchboard 5. The lighting switchboard 5 may have a function of turning at least some of the lighting fixtures into an energy saving lighting state. Sensing signals Md of 15 human sensors 311 to 313 are input to the lighting switchboard 5, and operation signals M1 to M5 and M6 of the main lighting switch 37 and the auxiliary lighting switch 38 are further input. The arrangement positions of the lighting control computer 4 and the lighting switchboard 5 are not particularly limited, and are not shown in FIG.

  FIG. 3 is a diagram schematically illustrating a method in which the lighting switchboard 5 switches between lighting and extinguishing of the lighting fixture. As shown in the figure, three control switches 52 to 54 are connected in parallel between the first lighting fixture 211 of the first substrate production line 81 and the AC power supply 51. The manual control switch 52 is turned on when the operation signal M1 of the main illumination switch 37 is in the on state, and is cut off when the operation signal M1 is in the off state. The automatic control switch 53 is turned on when the detection signal Md of the first person detection sensor 311 is on, and is cut off when the detection signal Md is off. The automatic control switch 53 corresponds to the person detection part lighting part of the present invention. By using the first person detection sensor 311, an automatic lighting function is realized. The system control switch 54 is controlled to be switched on and off by control from the lighting control computer 4.

  Eventually, the 1st lighting fixture 211 will light by one or more conduction | electrical_connection among the three control switches 52-54, and will light-extinguish when all three are interrupted | blocked. In the switching control of lighting and extinguishing of the remaining 14 lighting fixtures 212, 213, 221, 223, 231 and 233 on the floor 91, the sensing signal Md of the human sensor and the operation signals M1 to M5 of the main lighting switch 37 change. However, the control method itself does not change. In the switching control of turning on and off the indoor lighting fixture 26, the manual control switch 52 is controlled by the operation signal M6 of the sub-lighting switch 38, and the automatic control switch 53 is omitted.

(2. Operation and Action of Lighting Control System 1 of First Embodiment)
Next, operation | movement and an effect | action of the illumination control system 1 of 1st Embodiment are demonstrated according to the control flow of the illumination control computer 4. FIG. FIG. 4 is a flowchart showing a control flow of the illumination control computer 4. In step S1 in the figure, the call signal acquisition unit 41 of the lighting control computer 4 determines whether or not the call signal Sc is generated in the board production apparatuses (71 to 76).

  While the call signal Sc is not generated, the call signal acquisition unit 41 repeats Step S1 and Step S2. In step S2, the energy saving maintenance unit 42 maintains all the lighting fixtures in the extinguished state (all extinguished state). Thereby, a big energy saving effect occurs. However, when there is an operator on the floor 91, the luminaire can be turned on by the automatic lighting function of the human detection sensors 311 to 313 or the manual lighting function of the main lighting switch 37.

  When the call signal Sc is generated, the call signal acquisition unit 41 advances the execution of the control flow to step S3. In step S3, the call signal acquisition unit 41 confirms the board production line (any one of 81 to 85) and the board production apparatus (any one of 71 to 76) where the call signal Sc is generated. Further, the call signal acquisition unit 41 confirms the content of the factor included in the call signal Sc. Examples of the contents of the factor include a setup change factor, a supply factor, a replacement factor, and an abnormality factor (details will be described later). In the next step S <b> 4, the lighting control computer 4 transmits an operator call signal So to the portable terminal 49. The operator call signal So includes information indicating the board production line and board production apparatus where the call signal Sc is generated, and the contents of the factors.

  In step S5, the lighting control computer 4 determines a branch destination of the control flow according to the content of the factor. That is, the lighting control computer 4 advances the control flow to step S8 in the case of a setup change factor, step S6 in the case of a supply factor, step S7 in the case of a replacement factor, and step S11 in the case of an abnormal factor.

  Further, in step S6, the lighting control computer 4 determines a branch destination of the control flow according to the material or component to be replenished. That is, the illumination control computer 4 advances the execution of the control flow to step S10 when supplying electronic components, and advances the execution of the control flow to step S9 when supplying solder. In step S7, the illumination control computer 4 determines a branch destination of the control flow according to the replacement member. That is, the illumination control computer 4 advances the execution of the control flow to step S10 when replacing the mounting nozzle, and advances the execution of the control flow to step S9 when replacing the squeegee.

  Here, the setup change factor occurs when the actual production number of a certain type of substrate reaches the planned production number in the substrate production line (any one of 81 to 85). At this time, a setup change operation is required to change the type of substrate to be produced. In the setup change work, there are many cases where various types of electronic components mounted on the board are changed by the first electronic component mounting machine 73 or the second electronic component mounting machine 74. Therefore, the operator goes to the component member chamber 95 and returns with the component supply device placed on the transport carriage.

  Further, along with the change in the type of the board to be produced, the printing pattern data of the solder printer 71 and the data related to the electronic component mounting of the first electronic component mounting machine 73 and the second electronic component mounting machine 74 are changed. In addition, the inspection pattern data used by the printing inspection machine 72 and the board appearance inspection machine 75 is also changed. These data changing operations are automatically performed by the function of the line management computer of the lighting control computer 4. The operator confirms that the data changing operation has been properly performed with the respective board production apparatuses (71 to 75).

  Therefore, in step S8, the factor location lighting unit 43 identifies the board production line in which the setup change factor has occurred as the factor location, and lights the first to third lighting fixtures that share the board production line. Moreover, the related location lighting part 44 selects the interior lighting fixture 26 and makes it light by making the parts member room 95 which an operator may move for work into a related location.

  FIG. 5 is a plan view of the floor 91 exemplifying a situation in which the lighting control system 1 is operated in accordance with the setup change factor generated in the board production line. In the example of FIG. 5, a setup change factor occurs in the fourth substrate production line 84. The factor location lighting unit 43 lights the first to third lighting fixtures 241 to 243 that share the fourth substrate production line 84, and the related location lighting portion 44 lights the room lighting fixture 26. In FIG. 5 and subsequent figures, the flow line of movement of the operator is indicated by a thick broken line, and the lit lighting fixture is indicated by black for convenience.

  The operator who has confirmed the operator call signal So on the portable terminal 49 enters the floor 91 from the main entrance 92 and moves to the fourth substrate production line 84. At this time, the floor area including the passage from the main doorway 92 to the fourth substrate production line 84 is automatically illuminated by the third person detection sensor 333 and the third lighting device 233 of the third substrate production line 83. Next, the operator confirms the state of the already illuminated fourth substrate production line 84 and moves to the already illuminated component member chamber 95. At this time, the passage from the fourth board production line 84 to the component member chamber 95 is automatically illuminated by the first person detection sensor 331 and the first lighting fixture 231 in the third board production line 83.

  Accordingly, all the lighting fixtures 231, 233, 241, 242, and 243 and the room lighting fixture 26 are automatically turned on for the area where the operator may move for the setup change operation. Further, even if the operator temporarily moves to an area that is not assumed on the floor 91, the automatic lighting function by the human detection sensor works. In addition, since the entire fourth board production line 84 and the component member chamber 95 are already illuminated at the moment when the operator views the inside of the floor 91 from the main entrance 92, the work target location is easily understood.

  Next, a replenishment factor occurs when there is no material or parts in the board production line (any of 81 to 85). At this time, it is necessary to supply materials and parts. Examples of the material include solder to be supplied to the solder printer 71, and examples of the component include electronic parts to be supplied to the first electronic component mounting machine 73 and the second electronic component mounting machine 74. Even in the case of materials or parts other than those illustrated, when the replenishment target is the solder printer 71, the process of step S9 is performed, and the replenishment target is the first electronic component mounting machine 73 or the second electronic component mounting machine 74. The process of step S10 is performed. The operator will move to the parts place to pick up the refill solder and electronic parts.

  Further, the replacement factor occurs when the replacement member is replaced in the substrate production line (any one of 81 to 85). At this time, replacement work of the replacement member is required. For example, when a large amount of solder adheres to the squeegee of the solder printer 71 and automatic cleaning becomes difficult, replacement work is necessary. Further, for example, when the mounting success rate of the mounting nozzles of the first electronic component mounting machine 73 and the second electronic component mounting machine 74 is reduced, replacement work is required. Even in the case of a replacement member other than those illustrated, when the replacement target is the solder printer 71, the process of step S9 is performed, and the replacement target is the first electronic component mounting machine 73 or the second electronic component mounting machine 74. The process of step S10 is performed. The operator moves to the parts storage in order to pick up a spare squeegee or mounting nozzle.

  As described above, when a replenishment factor or replacement factor occurs in the solder printer 71, the execution of the control flow proceeds to step S9. The factor location lighting unit 43 lights the first lighting fixture of the board production line that shares the solder printer 71 that is the factor location. Further, there is only a parts place where the operator may move for work, and the parts place is already illuminated by the first lighting fixture. Therefore, the related part lighting unit 44 does not select a lighting fixture.

  FIG. 6 is a plan view of the floor 91 exemplifying a situation in which the lighting control system 1 is operated in accordance with the replenishment factor or replacement factor generated in the solder printer 71. In the example of FIG. 6, a replenishment factor or a replacement factor is generated in the solder printer 71 of the third board production line 83. For this reason, the factor location lighting part 43 lights the 1st lighting fixture 231 which shares the solder printer 71 of the 3rd board | substrate production line 84. FIG.

  The operator enters the floor 91 from the main doorway 92 and moves to the solder printer 71 of the third board production line 83. At this time, the floor area including the passage from the main doorway 92 to the solder printer 71 is the second and third person detection sensors 332 and 333 of the third board production line 83 and the second and third lighting fixtures 232 and 233. Automatically illuminated by. Next, the operator confirms the situation of the solder printer 71 that is already illuminated, and moves to the already illuminated third component storage area 983. Therefore, all the lighting fixtures 231, 232, and 233 are automatically turned on for the area where the operator may move. In addition, since the first lighting fixture 331 of the third substrate production line 83 is already turned on at the moment when the operator sees the inside of the floor 91 from the main entrance 92, the work target location is easy to understand.

  On the other hand, when a supply factor or a replacement factor occurs in the first electronic component mounting machine 73 or the second electronic component mounting machine 74, the execution of the control flow proceeds to step S10. The factor location lighting unit 43 lights the second lighting fixture of the board production line that shares the first electronic component mounting machine 73 or the second electronic component mounting machine 74 that is the factor location. Moreover, the related location lighting part 44 selects and lights up the 1st lighting fixture which shares the parts place which an operator may move for work.

  FIG. 7 is a plan view of the floor 91 exemplifying a situation in which the lighting control system 1 is operated according to a supply factor or a replacement factor generated in the electronic component mounting machine. In the example of FIG. 7, a supply factor or a replacement factor is generated in the first electronic component mounting machine 73 of the second board production line 82. For this reason, the factor location lighting part 43 lights the 2nd lighting fixture 322 which shares the 1st electronic component mounting machine 73 of the 2nd board | substrate production line 82. FIG. In addition, the related part lighting unit 44 selects and lights the first lighting fixture 321 sharing the second component storage place 982.

  The operator enters the floor 91 from the main entrance 92 and moves to the first electronic component mounting machine 73 of the second board production line 82. At this time, the floor area including the passage from the main doorway 92 to the first electronic component mounting machine 73 is automatically illuminated by the third person detection sensor 323 and the third lighting fixture 223 of the second board production line 82. . Next, the operator confirms the status of the first electronic component mounting machine 73 that is already illuminated, and moves to the second component storage place 982 that is already illuminated. Therefore, all the lighting fixtures 221, 222, and 223 are automatically turned on for the area where the operator may move. In addition, since the first and second lighting fixtures 221 and 222 of the second substrate production line 82 are already turned on at the moment when the operator sees the inside of the floor 91 from the main entrance 92, the work target location is easy to understand.

  Next, the abnormality factor means a case where some abnormality occurs in any of the substrate production apparatuses constituting the substrate production line (any of 81 to 85). At this time, inspection and investigation work by an operator, maintenance work for resuming operation, and the like are necessary. Abnormalities include malfunctions in the board production apparatus, inspection failures in the print inspection machine 72 and the board appearance inspection machine 75, and the like. In many cases, in order to investigate the cause of the abnormality, take countermeasures, and restart the operation, it is necessary to work on the entire board production line (any one of 81 to 85). That is, the operator goes back and forth through the entire board production line (any one of 81 to 85).

  For this reason, in step S11, the factor location lighting unit 43 lights one of the first to third lighting fixtures sharing the substrate production apparatus (any one of 71 to 76) in which the abnormality factor has occurred. Moreover, the related location lighting unit 44 uses the entire substrate production line (any one of 81 to 85) including the substrate production apparatus (any one of 71 to 76) in which an abnormality factor has occurred as a related location, and the first to third Turn on the luminaire. Furthermore, the related part lighting unit 44 may select and light the indoor lighting device 26 using the part member chamber 95 in which the inspection tool is stored as the related part.

  FIG. 8 is a plan view of the floor 91 exemplifying a situation in which the illumination control system 1 is operated according to an abnormality factor that has occurred in the board production line. In the example of FIG. 8, an abnormality factor has occurred in the substrate appearance inspection machine 75 of the fifth substrate production line 85. For this reason, the factor location lighting part 43 lights the 3rd lighting fixture 253 which shares the board | substrate external appearance inspection machine 75. FIG. Further, the related part lighting unit 44 lights the other first and second lighting fixtures 251 and 252 that share the fifth substrate production line 85.

  The operator enters the floor 91 from the main entrance 92 and moves to the fifth substrate production line 85. At this time, the floor area including the passage from the main doorway 92 to the fifth substrate production line 85 is the third person detection sensors 333 and 343 and the third lighting fixtures 233 and 243 of the third and fourth substrate production lines 83 and 84. Automatically illuminated by. Next, the operator checks and investigates the status of the fifth substrate production line 85 that is already illuminated. Therefore, all the lighting fixtures 233, 243, 251, 252, and 253 are automatically turned on for the area where the operator may move. In addition, since the entire fifth substrate production line 85 is already illuminated at the moment when the operator sees the inside of the floor 91 from the main entrance 92, the work target location is easy to understand.

  The operator takes measures according to the cause of the abnormality and resumes the operation of the board production line. Further, when the operator confirms that the substrate production line is operating well, the operator inputs a return command from the input device of the illumination control computer 4. The return command is a command for returning the energy saving maintenance unit 42. In step S12 following step S11 in FIG. 4, the illumination control computer 4 waits for an input of a return command, and when the return command is input, advances the execution of the control flow to step S13.

  The operator does not need to input a return command after performing the setup change work, the replenishment work, and the exchange work. After executing Steps S8, S9, and S10, the lighting control computer 4 advances the execution of the control flow to Step S13 and waits for the operator's work to end. Since the call signal Sc is canceled when the work is completed, the lighting control computer 4 advances the execution of the control flow to step S14.

  In step S14, the lighting control computer 4 waits for the elapse of a predetermined time, and when the predetermined time elapses, returns the execution of the control flow to step S1. The fixed time is set in consideration of the convenience for the operator to move away from the factor occurrence location, and is not essential. That is, the lighting control computer 4 may immediately return the execution of the control flow to step S1 when the call signal Sc is canceled in step S13. If another call signal is not generated in step S1 after returning, the energy saving maintaining unit 42 is restored in step 2 again, and the energy saving effect is generated again.

  Note that there may be a case where a plurality of call signals Sc are generated overlapping in time. In this case, the lighting control computer 4 executes the control flow shown in FIG. 4 for each call signal Sc. For this reason, the energy saving maintaining unit 42 is restored after all the call signals Sc are released.

  Next, the modification which changed the function of the energy-saving maintenance part 42 of 1st Embodiment is demonstrated. In the modified example, the energy saving maintaining unit 42 maintains the energy saving lighting state in which the power for illumination in the entire floor 91 is saved, not the all lights off state. FIG. 9 is a plan view of a floor 91 illustrating a situation in which the energy saving maintaining unit 42 maintains the energy saving lighting state in the modification of the first embodiment. As shown in the figure, while no factor is generated, the energy-saving maintaining unit 42 has only two of the second lighting fixture 222 of the second board production line 82 and the second lighting fixture 242 of the fourth board production line 84. Is turned on and the thinned-out lighting state is maintained with the others turned off. Even in this case, a large energy saving effect occurs.

  The energy saving lighting state is not limited to the above-described thinning lighting state, and may be a low luminance lighting state, a partial lighting state, or the like. In the low brightness lighting state, all the lighting fixtures are turned on, but the power consumption of each lighting lamp is saved and the brightness is lowered. In the partially lit state, each of the lighting fixtures has two or more illumination lamps, and at least one illumination lamp is turned off. Furthermore, it is also possible to combine a plurality of states described above. For example, the 2nd lighting fixture 222 of the 2nd board | substrate production line 82 made into the thinning-out lighting state and the 2nd lighting fixture 242 of the 4th board | substrate production line 84 can be made into the low-intensity with which power consumption was saved.

(3. Aspects and effects of the lighting control system 1 of the first embodiment)
The lighting control system 1 according to the first embodiment includes a plurality of lighting apparatuses that share and illuminate at least one of a plurality of production apparatuses (substrate production apparatuses (71 to 76)) and a floor 91 on which the plurality of production apparatuses are installed. The lighting control system 1 that controls (211 to 213, etc.), and a call that occurs in the first production device when a factor that requires work by the operator occurs in the first production device among the plurality of production devices The call signal acquisition unit 41 that acquires the signal Sc, and the energy saving that maintains a plurality of lighting fixtures in an extinguished state or an energy saving lighting state that saves lighting power in the entire floor 91 while the call signal Sc is not generated When the maintenance unit 42 and the call signal Sc are generated, the lighting apparatus sharing at least one of the first production device and the floor area around the first production device is turned on. When the causal part lighting unit 43 and the call signal Sc are generated, the relevant part corresponds to at least one of the production device other than the first production device and the floor area away from the first production device, and the operator Therefore, the lighting device 44 includes a related portion lighting unit 44 that variably selects and lights a lighting fixture that shares a related portion that may move in order based on the content of the factor.

  According to this, while the call signal Sc is not generated, the energy saving maintaining unit 42 functions to generate an energy saving effect. Then, when the call signal Sc is generated, the factor location lighting unit 43 automatically illuminates the factor occurrence location, and the related location lighting unit 44 automatically illuminates the related location. That is, the place where the operator performs work and the place where there is a possibility of moving are automatically illuminated, so that workability is improved and the work target place is easy to understand. Therefore, the lighting control system 1 of the first embodiment can achieve both an energy saving effect and good workability.

  Furthermore, the illumination control system 1 of the first embodiment is connected to a plurality of production apparatuses (substrate production apparatuses (71 to 76)) and can acquire a call signal Sc, and a plurality of illumination apparatuses (211 to 213 and the like). Is connected to the lighting switchboard 5 that can be turned on and off individually, and includes at least part of the functions of the call signal acquisition unit 41, the energy saving unit 42, the factor location lighting unit 43, and the related location lighting unit 44 A control computer 4 was provided.

  According to this, this invention can be rationally implemented using a computer apparatus. In particular, when the substrate production apparatus (71 to 76) is an illumination target, the illumination control computer 4 can also serve as a line management computer that manages the operation of the first to fifth substrate production lines 81 to 85. Hardware is effectively utilized.

  Furthermore, as related points, other production devices in the production line including the first production device, and a floor area including a passage from the entrance / exit of the floor 91 (main entrance 92) to the first production device, And at least one of materials and parts to be replenished to the first production apparatus, and a replacement member used in the first production apparatus (part member chamber 95, first to fifth part placement areas). 981 to 985) to one or more floor areas including a passage from the first production apparatus to the first production apparatus. According to this, the effect of improving workability becomes remarkable in the floor 91 in which a plurality of production apparatuses constitute a production line, and the floor 91 provided with doorways and parts member storage places.

  Furthermore, energy saving is maintained when the factor is eliminated by the work and the call signal Sc is released, when a certain time has elapsed after the call signal Sc is released, or when the operator inputs a return command. Part 41 returns. According to this, even when the operator performs work without movement or when the operator temporarily leaves the location where the factor is generated, the light is not turned off, and good workability is maintained. In addition, since the light is automatically turned off after the factors are eliminated, the energy saving effect occurs again.

  Furthermore, in the modification of 1st Embodiment, the energy-saving maintenance part 41 is the low-intensity lighting state which saved the power consumption of each lighting lamp of several lighting fixtures, or several lighting lamps of each of several lighting fixtures Partially lit state with part of the lamp turned off, thinned lit state with part of the lighting fixtures turned on and the remaining part turned off, or a combination of multiple states among the low-brightness lit state, partially lit state, and thinned lit state To maintain. According to this, the energy-saving maintenance part 41 can employ | adopt various energy-saving lighting states other than all the light extinction states.

  Furthermore, the lighting control system 1 according to the first embodiment lights up human detection sensors (311 to 313 and the like) that detect an operator located in the floor 91 and lighting fixtures that share the floor area around the detected operator. And a human-sensing location lighting section (automatic control switch 53). According to this, the effect of improving workability is ensured by using the human sensor together.

  In the lighting control system 1 of the first embodiment, each of the plurality of production apparatuses is a board production apparatus (71 to 76) that constitutes a board production line 81 to 85 for mounting electronic components on the board using solder. Yes, the factor is at least one of a setup change factor for changing the type of board, a supply factor for supplying solder or electronic parts, a replacement factor for replacement members used in the board production apparatus, and an abnormality factor occurring in the board production apparatus. Includes factors. According to this, on the floor 91 of the board production factory, it is possible to achieve both an energy saving effect while the call signal Sc is not generated and a good workability for various factors.

  Furthermore, when the factor is an abnormal factor, the related part includes other substrate production apparatuses in the substrate production lines 81 to 85 configured to include the first substrate production apparatus in which the factor has occurred. According to this, since the whole substrate production lines 81 to 85 on which the operator may move are automatically illuminated, workability is improved.

  Furthermore, when the factor is eliminated by the work, and when the substrate production lines 81 to 85 configured to include the first substrate production apparatus in which the factor has occurred resumes operation and a predetermined number of the substrates are successfully produced, Or when the operator who confirmed that the board | substrate production lines 81-85 comprised including the 1st board | substrate production apparatus restarted operation input the return command, the energy-saving maintenance part 42 resets. According to this, since the energy-saving maintenance part 42 returns after confirming favorable operation | movement of the board | substrate production lines 81-85, there is no fear of inadequate work.

(4. Lighting control system of the second embodiment)
Next, the illumination control system of the second embodiment will be described mainly with respect to differences from the first embodiment. The illumination control system of the second embodiment is the same as the first embodiment except that the human sensor and the automatic control switch 53 are not provided and the function of the related portion lighting unit 44 is different. In the second embodiment, there is no automatic lighting function by the human sensor, and the related part lighting unit 44 controls the lighting of the floor area including the passage.

  The operation and action of the illumination control system of the second embodiment will be described by taking the case of the setup change factor described in FIG. 5 as an example. FIG. 10 is a plan view of the floor 91 exemplifying a situation in which the lighting control system according to the second embodiment is operated according to the setup change factor generated in the board production line. In the example of FIG. 10, a setup change factor occurs in the fourth substrate production line 84. For this reason, as in the first embodiment, the factor location lighting unit 43 lights the first to third lighting fixtures 241 to 243 that share the fourth board production line 84, and the related location lighting unit 44 is used for indoor lighting. The appliance 26 is turned on.

  Unlike the first embodiment, the related portion lighting unit 44 includes a floor area including a passage from the main doorway 92 to the fourth board production line 84 and the fourth board production line 84 to the component member chamber 95. The floor area including the passage is the relevant part. That is, the related part lighting unit 44 lights the third and first lighting fixtures 233 and 231 that share the third substrate production line 83 to facilitate the movement of the operator. Accordingly, all the lighting fixtures 231, 233, 241, 242, and 243 and the room lighting fixture 26 are automatically turned on for the area where the operator may move for the setup change operation.

  In the lighting control system according to the second embodiment, when the factor is any one of a setup change factor, a supply factor, and a replacement factor, the related part is placed with at least one of solder and electronic components and a replacement member. It includes a floor area including a passage from the component parts storage area to the first board production apparatus where the factor is generated. According to this, since the passage where the operator may move is automatically illuminated, the workability is remarkably improved without using a human sensor.

(5. Application and modification of embodiment)
In the first embodiment, the energy saving maintaining unit 42 may be returned after the operator inputs a return command after performing the setup change work, the replenishment work, and the replacement work. In this case, the illumination control computer 4 advances the execution of the control flow to step S12 after steps S8, S9, and S10, and thereafter performs the same control as when an abnormal factor occurs. Further, in step S12 when an abnormality factor occurs, a return signal for the board production lines 81 to 85 may be waited for instead of a return command from the operator. The return signal is input from the board production lines 81 to 85 to the illumination control computer 4 via the hub device 47 when the board production lines 81 to 85 resume operation and a predetermined number of boards are produced satisfactorily. Is done.

  Furthermore, the number of board production lines, the line configuration, the arrangement of lighting fixtures and parts member storage in the floor 91 can be variously changed. In this case, the related part lighting unit appropriately selects a lighting fixture to be turned on according to the factor, and turns on the lighting fixture. The illumination control system of the present invention can also be implemented in a factory where a plurality of production apparatuses related to various products other than the substrate are installed. The present invention can have various other applications and modifications.
