[Technical Field]

[0001] The present invention relates to a technique for monitoring the state of power consumption in a power supply system. [Background technology]

[0002] Patent Document 1 discloses a technology for monitoring the power consumed by component mounting devices used in component mounting lines. It proposes utilizing the results of power monitoring as useful information for reducing power consumption in particular. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5196605 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when a power supply system supplies power to multiple operating units, and each operating unit consumes that power to perform its operation, workers may be able to easily gain insight into how to reduce power consumption by checking the power consumption status at two or more points.

[0005] The present invention has been made in view of the above-mentioned problems, and has as its object to make it possible to easily check the power consumption status at two or more points in a power supply system that supplies power to a plurality of operating units. [Means for solving the problem]

[0006] The power monitoring device of the present invention is a power supply system that supplies power to a plurality of operating units that perform operations assigned to each of the operating units, and is equipped with a data acquisition unit that acquires power data indicating the power flowing into each of two or more target operating units among the plurality of operating units, and a data presentation unit that creates a monitoring screen that shows the power flow status into each of the target operating units based on the power data acquired by the data acquisition unit and displays it on a display.

[0007] The power monitoring method of the present invention is provided in a power supply system that supplies power to a plurality of operational units that perform operations assigned to each of the operational units, and includes the steps of acquiring power data indicating the power flowing into each of two or more target operational units among the plurality of operational units, and creating a monitoring screen based on the power data and displaying the screen on a display, the monitoring screen indicating the power flow status into each of the target operational units for each of the target operational units.

[0008] A power monitoring program according to the present invention causes a computer to execute the above-described power monitoring method.

[0009] A recording medium according to the present invention records the above-described power monitoring program in a computer-readable manner.

[0010] In the present invention (power monitoring device, power monitoring method, power monitoring program, and recording medium) configured in this manner, power data indicating the power flowing into each of two or more target operational units among a plurality of operational units is acquired. Then, a monitoring screen showing the power flow status of each target operational unit is created based on the power data and displayed on the display. Therefore, by visually checking the monitoring screen displayed on the display, an operator can easily check the power consumption status of two or more points in the power supply system.

[0011] The power monitoring device may also be configured to further include a storage unit that stores the power data acquired by the data acquisition unit, and the data presentation unit creates a monitoring screen based on the power data read from the storage unit. With this configuration, an operator can easily check the past power consumption status of the power supply system at two or more points.

[0012] The power monitoring device may also be configured such that the data presentation unit updates the monitoring screen each time the data acquisition unit acquires power data. With this configuration, an operator can easily check the power consumption status of the power supply system at two or more points in real time.

[0013] The power monitoring device may also be configured so that the data presentation unit creates a monitoring screen that shows, for each target operating unit, the change over time in the power flowing into the target operating unit. With this configuration, an operator can easily check the change over time in power at two or more points.

[0014] The power monitoring device may also be configured so that the data presentation unit acquires the time when a change occurs in the conditions for an operational unit to perform an operation, and the data presentation unit compares the power inflow status for the target operational unit before and after the time when the change occurred in the conditions, and creates a monitoring screen showing the status for each target operational unit. With this configuration, an operator can easily check the power consumption status before and after the change in the conditions for the operational unit to perform an operation.

[0015] The power monitoring device may be configured so that, in order to execute a predetermined process on a workpiece, a plurality of operation units execute the operations assigned to them, a data acquisition unit acquires execution status data indicating the execution status of the predetermined process, and a data presentation unit creates a monitoring screen indicating the change in the execution status of the predetermined process over time based on the execution status data. With this configuration, the worker can easily compare the change in power over time with the execution status of the predetermined process on the workpiece.

[0016] The power monitoring device may be configured so that, to execute a predetermined process on a workpiece, a plurality of operation units execute the operations assigned to them, a data acquisition unit acquires workpiece identification data that identifies the workpiece to be processed, and a data presentation unit creates a monitoring screen based on the workpiece identification data, which shows the power consumed to execute the predetermined process on the workpiece in association with the workpiece. With this configuration, the worker can easily compare the workpiece to be processed with the power required to execute the predetermined process on the workpiece.

[0017] The power monitoring device may be configured so that, in order to execute a predetermined process on a workpiece, a plurality of operational units execute the operations assigned to them, and the data presentation unit creates a monitoring screen that shows the power flowing into a target operational unit during the execution of the predetermined process on a plurality of workpieces that make up a single product, in association with the single product. With this configuration, workers can easily check the power required to manufacture a single product.

[0018] Various specific examples of the target operation unit can be envisioned.

[0019] For example, the power monitoring device may be configured so that the two or more target operating units are any of a printing machine that prints solder on a board, a printing inspection machine that inspects the printed state of the solder on the board, a component mounting machine that places components on a board with solder printed on it, a mounting inspection machine that inspects the state of the components placed on the board, a reflow machine that heats a board with components mounted on it, and a reflow inspection machine that inspects the state of the components on the reflowed board.

[0020] The power monitoring device may also be configured so that the two or more target operating units include a circuit protector and a secondary unit into which power flows via the circuit protector.

[0021] The power monitoring device may also be configured so that the two or more target operation units include a breaker and a circuit protector into which power flows via the breaker. [Effects of the Invention]

[0022] As described above, according to the present invention, it is possible to easily check the power consumption status at two or more points in a power supply system that supplies power to a plurality of operating units. [Brief explanation of the drawings]

[0027] Fig. 1B is a block diagram showing an example of a power supply system provided in a board production system. As shown in Fig. 1B, board production system 1 has power supply system 7 that supplies power from power distribution facility 12 to devices 2, 3A-3C, 4A-4C, and 5.

[0031] The power supply line 71 has a wiring 71d that branches off from the power distribution facility 12 and is connected to the component mounter 4B, and a power meter Pd is provided on the wiring 71d.

[0032] The power supply line 71 has a wiring 71e that branches off from the power distribution facility 12 and is connected to the component mounter 4C, and a power meter Pe is provided on the wiring 71e. The power meter Pe measures the power flowing into the component mounter 4C among the devices 2, 3A to 3C, 4A to 4C, and 5, and transmits the measured power to the computer 6.

[0033] The power supply line 71 has a wiring 71f that branches off from the power distribution facility 12 and is connected to the substrate inspection machine 3B, and a power meter Pf is provided on the wiring 71f. The power meter Pf measures the power flowing into the substrate inspection machine 3B among the devices 2, 3A to 3C, 4A to 4C, and 5, and transmits the measured power to the computer 6.

[0034] The power supply line 71 has wiring 71g that branches off from the power distribution facility 12 and is connected to the reflow furnace 5, and a power meter Pg is provided on the wiring 71g.

[0036] The printer 2 performs the operations described below with reference to Figures 2 and 3 using the power flowing into the printer 2 via wiring 71a. The board inspection machines 3A, 3B, and 3C perform the operations described below with reference to Figure 4 using the power flowing into them via wiring 71b, 71f, and 71h.

[0037] FIG. 2 is a front view showing a schematic diagram of a printer provided in a board production line. FIG. 3 is a block diagram showing the electrical configuration of the printer in FIG. 2. FIG. 2 shows the horizontal X direction, the horizontal Y direction perpendicular to the X direction, and the vertical Z direction. The printer 2 performs a printing operation to print solder on a board B. The printer 2 includes a mask holding unit 21 that holds a mask K horizontally, a print head 22 arranged above the mask K, a head driving mechanism 23 that drives the print head 22, and a board driving mechanism 24 arranged below the mask K. The printer 2 further includes a main control unit 201 including a processor or the like, and a memory unit 202 including an SSD (Solid State Drive) or the like. Then, the main control unit 201 controls the drive mechanisms 23 and 24 in accordance with the printing program stored in the storage unit 202, so that the substrate B held by the substrate drive mechanism 24 faces the mask K from below, while the tip of the squeegee 221 of the print head 22 slides in the Y direction on the upper surface of the mask K. As a result, the solder supplied to the upper surface of the mask K is printed on the upper surface of the substrate B through the pattern holes that penetrate the mask K.

[0038] The printing press 2 also includes a drive control unit 203 that controls the operation of movable parts provided in the device, and the main control unit 201 controls the driving of the drive mechanisms 23 and 24 via the drive control unit 203. The printing press 2 also includes a display unit 204 configured, for example, as an LCD display, and an input unit 205 configured as input devices such as a keyboard and a mouse. Therefore, an operator can check the operating status of the printing press 2 by checking the contents displayed on the display unit 204, and can input commands to the printing press 2 by operating the input unit 205. The display unit 204 and the input unit 205 may be integrated into a touch panel.

[0039] The head drive mechanism 23 has a Y-axis motor M22y that drives the print head 22 in the Y direction, a Z-axis motor M22z that drives the print head 22 in the Z direction, and a rotation motor M22r that rotates the squeegee 221. These motors M22y, M22z, and M22r are servo motors. The drive control unit 203 adjusts the angle of the squeegee 221 using the rotation motor M22r, while lowering the print head 22 toward the mask K using the Z-axis motor M22z, so that the squeegee 221 comes into contact with the top surface of the mask K. Furthermore, the drive control unit 203 drives the print head 22 in the Y direction using the Y-axis motor M22y, causing the squeegee 221 to slide over the top surface of the mask K.

[0040] The substrate driving mechanism 24 is disposed below the mask K held by the mask holding unit 21, and has the function of aligning the position of the substrate B with respect to the mask K. The substrate driving mechanism 24 has a pair of conveyors 241 that transport the substrate B in the X direction, a substrate holding part 242 that holds the substrate B received from the conveyors 241, and a flat movable table 243 that supports the conveyors 241 and the substrate holding part 242.

[0041] The pair of conveyors 241 are arranged parallel to each other in the X direction with a gap in the Y direction, and their upper surfaces support both ends of the board B in the Y direction from below. The board driving mechanism 24 is also provided with a conveyor motor M241 that drives these conveyors 241. When the conveyor motor M241 receives a command from the drive control unit 203 and drives each conveyor 241, each conveyor 241 transports the board B in the X direction, thereby carrying the board B into or out of the printing machine 2.

[0042] The substrate holding unit 242 has a flat lift table 244 and a slide support 245 that is slidable in the Z direction relative to the movable table 243, and the lift table 244 is supported on the upper end of the slide support 245. In addition, a plurality of backup pins 246 are erected in the Z direction on the upper surface of the lift table 244 and are arranged at intervals in the X and Y directions. Furthermore, a backup motor M246 is provided in the substrate holding unit 242, and the backup motor M246, upon receiving a command from the drive control unit 203, lifts and lowers the slide support 245, thereby lifting and lowering the backup pins 246 together with the lift table 244. For example, when the conveyor 241 carries in the substrate B, the backup motor M246 positions the upper ends of the backup pins 246 below the upper surface of the conveyor 241. Then, when the conveyor 241 carries in the board B directly above the backup pins 246, the backup motor M246 raises the backup pins 246, causing the upper ends of the backup pins 246 to protrude upward from the upper surface of the conveyor 241. As a result, the board B is transferred from the upper surface of the conveyor 241 to the upper ends of the backup pins 246.

[0043] The substrate holder 242 also has a pair of clamp plates 247 arranged at a distance in the Y direction above the pair of conveyors 241. The drive control unit 203 then raises the substrate B on the backup pins 246 between the pair of clamp plates 247, and the clamp plates 247 move closer to each other, thereby clamping the substrate B. Specifically, the storage unit 202 stores lift control data indicating the rotation angle of the backup motor M246 that causes the height of the upper surface of the substrate B to match the height of the upper surface of the clamp plates 247. The backup motor M246 then lifts the substrate B by the lift amount indicated by the lift control data.

[0044] Furthermore, the substrate driving mechanism 24 has a ball screw 248 that raises and lowers the movable table 243, and an elevator motor M248 that drives the movable table 243 in the Z direction by rotating the ball screw 248. Therefore, the drive control unit 203 can drive the conveyor 241 and substrate holder 242 arranged on the movable table 243 in the Z direction by controlling the elevator motor M248. For example, when positioning the loaded substrate B with respect to the mask K, the drive control unit 203 adjusts the position of the substrate B clamped to the clamp plate 247 in the Z direction using the elevator motor M248. As a result, the upper surfaces of the clamp plate 247 and the substrate B come into contact with the lower surface of the mask K.

[0045] Fig. 4 is a front view showing a schematic diagram of an example of a board inspection machine provided in a board production line. Board inspection machines 3A, 3B, and 3C each have the same configuration as shown in Fig. 4. Therefore, in Fig. 4, board inspection machines 3A, 3B, and 3C are not distinguished from one another and are referred to as board inspection machine 3.

[0046] Based on the appearance of board B, board inspection machine 3 performs inspection work to determine whether the condition of the solder printed on board B (board inspection machines 3A, 3B, 3C) and the condition of the components mounted on board B (board inspection machines 3B, 3C) are good or bad. This board inspection machine 3 comprises a main control unit 301 and a user interface 302. Main control unit 301 is composed of a processor, etc., and controls the inspection work. User interface 302 is composed of, for example, a touch panel, and a user can set conditions for the inspection and check the results of the inspection via user interface 302.

[0047] Furthermore, the substrate inspection machine 3 includes a substrate transport unit 32 that transports the substrate B, an inspection head 33 that faces the substrate B from above, and a drive unit 34 that drives the inspection head 33. The substrate transport unit 32 has a pair of conveyors 321 and a conveyor motor M321 that drives the conveyor 321. When the conveyor motor M321 drives the conveyor 321, the conveyor 321 transports the substrate B in the X direction. The substrate transport unit 32 fixes the substrate B that has been brought in from the outside at a predetermined holding position (the position of the substrate B in FIG. 3) and transports the substrate B from the holding position to the outside. The substrate transport unit 32 fixes the substrate B at the holding position while holding the surface Bs of the substrate B horizontally. The inspection head 33 is a camera that takes images using a solid-state image sensor 331. The driving unit 34 is an XY robot, and drives the inspection head 33 in the X direction by an X-axis motor M34x, and drives the inspection head 33 in the Y direction by a Y-axis motor M34y. These motors M34x and M34y are servo motors.

[0048] The main control unit 301 adjusts the positional relationship between the inspection head 33 and the board B in the X and Y directions using the X-axis motor M34x and the Y-axis motor M34y, while causing the inspection head 33 to capture an image of the inspection target position on the board B. Then, based on the image captured by the inspection head 33, the main control unit 301 inspects the quality of the solder and the components on the board B.

[0049] Fig. 5 is a plan view showing a schematic configuration of an example of a component mounter provided in a board production line. Fig. 6 is a block diagram showing the electrical configuration of the component mounter of Fig. 5. Each of component mounters 4A, 4B, and 4C has the configuration shown in Fig. 5 and Fig. 6 in common. Therefore, in Fig. 5 and Fig. 6, component mounters 4A, 4B, and 4C are referred to as component mounter 4 without distinction.

[0050] The mounter 4 performs a mounting operation to mount a component E on a board B. As shown in FIG. 6 , the mounter 4 includes a control unit 400 that performs overall control of the entire device. The control unit 400 includes a main controller 401 configured with a processor or the like, a storage unit 402 configured with a hard disk drive or the like, a drive controller 403 that controls the drive system of the mounter 4, and an air controller 404 that controls the air supply system of the mounter 4. The main controller 401 controls the drive controller 403 in accordance with a program stored in the storage unit 402, thereby performing component mounting according to the procedure defined by the program. The mounter 4 is also provided with a display / operation unit 405. The main controller 401 displays the operating status of the mounter 4 on the display / operation unit 405 and receives instructions input from an operator via the display / operation unit 405.

[0051] As shown in FIG. 5, the component mounter 4 includes a transport unit 41 that transports a board B in the X direction (board transport direction). The transport unit 41 includes a pair of conveyors 411 arranged in parallel in the X direction and a conveyor motor M411 that drives the conveyors 411. When the conveyor motor M411 drives the conveyors 411, the conveyors 411 transport the board B in the X direction. The spacing between the conveyors 411 is changeable in the Y direction (width direction) that is perpendicular to the X direction, and the transport unit 41 adjusts the spacing between the conveyors 411 according to the width of the board B being transported. The drive control unit 403 controls the conveyor motor M411 to transport the board B from the upstream side in the X direction, which is the board transport direction, to a predetermined work position (the position of board B in FIG. 5), and transport the board B, on which components E have been mounted at the work position, downstream in the X direction.

[0052] Two component supply units 42 are arranged side by side in the X direction on each side of the transport unit 41 in the Y direction, and each component supply unit 42 has multiple tape feeders 421 arranged side by side in the X direction. Each component supply unit 42 has multiple component supply locations 422 arranged side by side in the X direction, and a tape feeder 421 that supplies components E to each component supply location 422 is detachably attached to each component supply location 422. A component supply reel around which a carrier tape is wound is disposed for each tape feeder 421, and the carrier tape that carries small pieces of components E, such as integrated circuits, transistors, and capacitors, at predetermined intervals is loaded into each tape feeder 421. Each tape feeder 421 has a feed motor M421 that intermittently drives the carrier tape to supply components E to the component supply location 422 at the leading end of the tape feeder 421.

[0053] The component mounter 4 is also provided with a pair of Y-axis rails 43 extending in the Y direction, a Y-axis ball screw 44 extending in the Y direction, and a Y-axis motor M44 (servo motor) that rotates and drives the Y-axis ball screw 44. An X-axis rail 45 is supported on the pair of Y-axis rails 43 so as to be movable in the Y direction and is fixed to the nut of the Y-axis ball screw 44. An X-axis ball screw 46 extending in the X direction and an X-axis motor M46 (servo motor) that rotates and drives the X-axis ball screw 46 are attached to the X-axis rail 45. A head unit 47 is supported on the X-axis rail 45 so as to be movable in the X direction and is fixed to the nut of the X-axis ball screw 46. Therefore, the drive control unit 403 can rotate the Y-axis ball screw 44 using the Y-axis motor M44 to move the head unit 47 in the Y direction, or can rotate the X-axis ball screw 46 using the X-axis motor M46 to move the head unit 47 in the X direction.

[0054] The head unit 47 has multiple mounting heads 48 arranged in a line in the X direction. Each mounting head 48 is provided with a Z-axis motor M48 (servo motor) that drives the mounting head 48 in the Z direction. The drive control unit 403 uses the Z-axis motor M48 to lower the mounting head 48 toward the component E at the component supply location 422, thereby bringing the nozzle at the bottom of the mounting head 48 into contact with the component E. In this state, the air control unit 404 generates negative pressure in the nozzle to pick up the component E. Furthermore, the drive control unit 403 lowers the mounting head 48, which picks up the component E to the nozzle, toward the board B, thereby bringing the component E into contact with the board B. In this state, the air control unit 404 generates positive pressure in the nozzle to mount the component E on the board B. The drive control unit 403 supplies negative and positive pressure to the nozzle at the bottom of the mounting head 48 by opening and closing an electromagnetic valve provided in a pipe connecting a source of negative and positive pressure to the mounting head 48.

[0055] 7 is a front view showing a schematic diagram of an example of a reflow furnace provided in a board production line. Reflow furnace 5 performs a reflow operation by heating board B to melt the solder printed on board B. This reflow furnace 5 includes heater 511 and heater driver 512 that drives heater 511. Heater 511 is, for example, an electric heating wire, and generates heat by the current supplied by heater driver 512.

[0056] Furthermore, the reflow furnace 5 includes a substrate transport unit 52 that transports the substrate B. The substrate transport unit 52 has a pair of conveyors 521 and a conveyor motor M521 that drives the conveyor 521, and when the conveyor motor M521 drives the conveyor 521, the conveyor 521 transports the substrate B in the X direction. The heater 511 faces the substrate B transported by the conveyor 521 and heats the substrate B. This melts the solder on the substrate B.

[0057] FIG. 8 is a block diagram showing the configuration of a computer. Computer 6 has a calculation unit 61 formed of a CPU (Central Processing Unit) or the like, and a storage unit 62 formed of a storage device such as an SSD (Solid State Drive). Computer 6 also has a UI (User Interface) 63. UI 63 has input devices such as a keyboard or a mouse, and an output device such as a display. Note that the input and output devices of UI 63 do not need to be configured separately, and may be configured integrally with a touch panel display. Computer 6 also has a communication unit 64 that communicates with board production line 11. Communication by communication unit 64 may be either wireless or wired.

[0058] Storage unit 62 stores a power monitoring program 621 for use by calculation unit 61 to monitor the power consumed in board production line 11. Power monitoring program 621 is downloaded from, for example, an external server (recording medium) and stored in storage unit 62. By executing power monitoring program 621, calculation unit 61 receives, via communication unit 64, the power values ​​measured by each of the multiple power meters Pa to Ph provided on board production line 11, and stores the received values ​​in storage unit 62 as power data 622. Calculation unit 61 monitors the power consumed in board production line 11 based on power data 622.

[0059] Fig. 9A is a flowchart showing a first example of power monitoring, Fig. 9B is a diagram schematically showing power log data created by the power monitoring of Fig. 9A in table format, and Fig. 9C is a diagram schematically showing a monitoring screen created based on power data acquired by the power monitoring of Fig. 9 A. The flowchart of Fig. 9A is executed by the calculation unit 61 based on the power monitoring program 621.

[0060] In step S101, the calculation unit 61 determines whether a predetermined sampling time has elapsed. If it determines that the sampling time has elapsed ("YES" in step S101), the calculation unit 61 acquires the power values ​​(power data 622) measured by each of the power meters Pa to Ph via the communication unit 64 (step S102). In step S103, the calculation unit 61 creates power log data 623 (FIG. 9B) including the power data 622 and stores it in the storage unit 62. As shown in FIG. 9B, the power log data 623 indicates, in association with each other, the device to which the power indicated by the power data 622 is to be supplied, the time at which the power data 622 was acquired, and the value of the power data 622.

[0061] Specifically, the calculation unit 61 creates power log data 623 that associates power data 622 acquired from the power meter Pa via the communication unit 64, the printing machine 2 to which the power indicated by the power data 622 will flow, and the time at which the power data 622 was acquired, and stores the data in the memory unit 62.

[0062] The calculation unit 61 creates power log data 623 that associates power data 622 acquired from the power meters Pb, Pf, and Ph via the communication unit 64 with the board inspection machines 3A, 3B, and 3C to which the power indicated by the power data 622 will flow, and the time at which the power data 622 was acquired, and stores the data in the memory unit 62.

[0063] The calculation unit 61 creates power log data 623 that associates power data 622 acquired from the power meters Pc, Pd, and Pe via the communication unit 64 with the component mounters 4A, 4B, and 4C that will receive the power indicated by the power data 622, and the time at which the power data 622 was acquired, and stores the data in the memory unit 62.

[0064] The calculation unit 61 creates power log data 623 that associates power data 622 acquired from the power meter Pg via the communication unit 64, the reflow furnace 5 to which the power indicated by the power data 622 is to be supplied, and the time at which the power data 622 was acquired, and stores the data in the memory unit 62.

[0065] In step S104, the calculation unit 61 creates a monitoring screen Ga shown in Fig. 9C based on the power log data 623 read from the storage unit 62, and displays it on the display of the UI 63. The monitoring screen Ga shows the change over time in the power flowing into each of the devices 2, 3A to 3C, 4A to 4C, and 5 as a graph with the horizontal axis representing time and the vertical axis representing power. Every time new power data 622 is acquired, the calculation unit 61 updates the monitoring screen Ga displayed on the display of the UI 63.

[0066] Then, the process returns to step S101. In this manner, steps S102 to S104 are repeatedly executed every time the sampling time elapses.

[0067] In the embodiment described above, power data 622 indicating the power flowing into each of all of the devices 2, 3A-3C, 4A-4C, and 5 (target operating units) among the multiple devices 2, 3A-3C, 4A-4C, and 5 (operating units) included in board production line 11 is acquired (step S102). Then, a monitoring screen Ga showing the power flow status for each of the devices 2, 3A-3C, 4A-4C, and 5 is created based on the power data 622 and displayed on the display of UI 63 (steps S103 and S104). Therefore, by visually checking the monitoring screen Ga displayed on the display of UI 63, an operator can easily check the power consumption status of power supply system 7 at two or more points.

[0068] The system also includes a storage unit 62 that stores power data 622 acquired by a communication unit 64 (data acquisition unit). The calculation unit 61 (data presentation unit) then creates a monitoring screen Ga based on the power data 622 read from the storage unit 62. With this configuration, the operator can easily check the past power consumption status in the power supply system 7 at two or more points.

[0069] Furthermore, the calculation unit 61 (data presentation unit) updates the monitoring screen Ga every time the communication unit 64 (data acquisition unit) acquires the power data 622. With this configuration, the worker can easily check the power consumption status in the power supply system 7 at two or more points in real time.

[0070] The calculation unit 61 (data presentation unit) also creates a monitoring screen Ga that shows the time change in the power flowing into the devices 2, 3A to 3C, 4A to 4C, and 5 for each of the devices 2, 3A to 3C, 4A to 4C, and 5. With this configuration, the operator can easily check the time change in power at two or more points.

[0071] Fig. 10A is a flowchart showing an example of event monitoring executed in a second example of power monitoring, Fig. 10B is a diagram schematically showing, in table format, event log data created by the event monitoring of Fig. 10A, and Figs. 10C and 10D are diagrams schematically showing monitoring screens created based on the event log data acquired by the event monitoring of Fig. 10A. The flowchart of Fig. 10A is executed by the calculation unit 61 based on the power monitoring program 621.

[0072] When the calculation unit 61 determines that an event has occurred in any of the devices 2, 3A to 3C, 4A to 4C, and 5 ("YES" in step S201), it creates event log data 624 (FIG. 10B) including the details of the event and stores it in the storage unit 62. Examples of the details of the event include optimization or a change in motor settings. As shown in FIG. 10B, the event log data 624 indicates the details of the event (e.g., optimization) in association with the time when the event occurred.

[0073] That is, the calculation unit 61 of the computer 6 creates board data for each of the mounters 4A to 4C indicating the procedure for mounting the component E on the board B, and the mounters 4A to 4C mount the component E on the board B according to the procedure indicated in the board data received from the communication unit 64 of the computer 6. The calculation unit 61 also optimizes the procedure indicated by the board data at an appropriate timing. When the calculation unit 61 executes the optimization, it determines that an event (optimization) has occurred.

[0074] The various motors described above operate based on a speed profile. This speed profile indicates an acceleration period during which the motor speed is accelerated from zero to a maximum speed, a constant speed period during which the motor speed is maintained at the maximum speed, and a deceleration period during which the motor speed is decelerated from the maximum speed to zero. The operator can change each parameter (acceleration period, constant speed period, deceleration period, or maximum speed) that defines the speed profile by operating, for example, the UI 63. When the parameters of the speed profile are changed, the calculation unit 61 determines that an event (a change in motor settings) has occurred.

[0075] For example, when an operator performs an operation on UI 63 to specify a comparison of power consumption before and after optimization, calculation unit 61 displays monitoring screen Gb shown in Fig. 10C on the display of UI 63. Specifically, calculation unit 61 displays, for each of devices 2, 3A-3C, 4A-4C, and 5, power consumption Wa1-Wh1 per predetermined unit time (e.g., 10 minutes, 15 minutes, 30 minutes, or 60 minutes) in board production performed before the time when optimization was performed, and power consumption Wa2-Wh2 per predetermined unit time in board production performed after the time when optimization was performed.

[0076] Alternatively, when the operator performs an operation on UI 63 to specify a comparison of power consumption before and after a motor setting change, calculation unit 61 displays monitoring screen Gc shown in Fig. 10D on the display of UI 63. Specifically, calculation unit 61 displays, for each of devices 2, 3A-3C, 4A-4C, and 5, power consumption Wa3-Wh3 per predetermined unit time (e.g., 10 minutes, 15 minutes, 30 minutes, or 60 minutes) in board production executed before the time when the motor setting change was performed, and power consumption Wa4-Wh4 per predetermined unit time in board production executed after the time when the motor setting change was performed.

[0077] In the embodiment described above, the calculation unit 61 (data presentation unit) acquires the time when a change occurred in the conditions under which at least one of the devices 2, 3A-3C, 4A-4C, and 5 executes its operation (step S202). The calculation unit 61 then compares the power inflow status for the devices 2, 3A-3C, 4A-4C, and 5 (target operating units) before and after the time when the conditions were changed, and creates monitoring screens Gb and Gc showing the devices 2, 3A-3C, 4A-4C, and 5, respectively (FIGS. 10C and 10D). With this configuration, the operator can easily check the power consumption status before and after the change in the conditions under which the devices 2, 3A-3C, 4A-4C, and 5 execute their operations.

[0078] Figure 11A is a flowchart showing an example of work data transmission performed in the third example of power monitoring, Figure 11B is a flowchart showing an example of device log data creation performed in the third example of power monitoring, Figures 11C and 11D are figures showing an example of device log data created by the flowchart of Figure 11B, and Figure 11E is a figure showing an example of a monitoring screen created based on the device log data of Figures 11C and 11D.

[0079] 11A is executed by each of the devices 2, 3A to 3C, and 4A to 4C. Since the contents of the work data transmission executed by each of the devices 2, 3A to 3C, and 4A to 4C are common, the component mounter 4 will be used as an example for explanation here.

[0080] When the mounter 4 carries in board B (work) (step S301), it acquires the board ID (work ID) attached to board B (step S302). Specifically, for example, the mounter 4 acquires the board ID by recognizing the board ID from an image captured by a camera facing board B from above. Furthermore, when the mounter 4 carries out board B (step S303), it associates the carry-in / out time with the board ID and transmits them to the computer 6 (step S304). Here, the carry-in / out time includes the carry-in time and the carry-out time, where the carry-in time is the time when carrying board B into the mounter 4 starts in step S301, and the carry-out time is the time when carrying board B out of the mounter 4 is completed in step S304.

[0081] 11B, the calculation unit 61 of the computer 6 acquires a board ID (work ID) from the mounter 4 via the communication unit 64 (step S401), and then acquires the name (work name) of board B corresponding to the board ID and the production lot number of board B (step S402). For example, the storage unit 62 stores a database in which the name and production lot number of board B are associated with the board ID, and the calculation unit 61 acquires the name and production lot number of board B by consulting this database. The calculation unit 61 also assigns a serial number to the board ID (step S403).

[0082] Furthermore, the calculation unit 61 calculates the amount of power consumed by the mounter 4 during the carry-in / out period from when the mounter 4 carries in the board B until when it carries it out (step S404). Specifically, the amount of power flowing into the mounter 4 during the period from the carry-in time to the carry-out time (carry-in / out period) is calculated based on the power data 622 associated with the time of the period. In other words, the amount of power flowing into the mounter 4 is calculated by integrating the power values ​​measured by the power meter Pb, Pc, or Pd over the carry-in / out period. Then, the calculation unit 61 associates the name of board B (work name), the production lot number of board B, the serial number assigned to board B, and the amount of power consumed during the carry-in / out period (power consumption) of board B, and stores them in the storage unit 62 as apparatus log data 625.

[0083] Such device log data 625 is created for each of the devices 2, 3A to 3C, and 4A to 4C. Note that Fig. 11C shows the device log data 625 created for the mounter 4A, and Fig. 11D shows the device log data 625 created for the mounter 4B.

[0084] For example, when an operator operates the UI 63 to specify a comparison between the total amount of power consumed by each board B (serial number) in each of the mounters 4A and 4B during the loading and unloading period of the board B, the calculation unit 61 displays the monitoring screen Gd shown in Fig. 11E on the display of the UI 63. Specifically, the sum of the 10 Wh of power consumed by the mounter 4A during the period from when the board B with serial number "0001" was loaded into the mounter 4A until it was unloaded (Fig. 11C) and the 10 Wh of power consumed by the mounter 4B during the period from when the board B with serial number "0001" was loaded into the mounter 4B until it was unloaded (Fig. 11D) is calculated as 20 Wh and displayed on the monitoring screen Gd. The same applies to the boards B with serial numbers "0002 to 0004."

[0085] In the embodiment described above, in order to perform mounting work (predetermined processing) on ​​board B (work), multiple mounters 4A, 4B (operating units) perform the mounting work assigned to them, respectively. In response to this, the calculation unit 61 (data acquisition unit) acquires a board ID (work identification data) that identifies board B, which is the target of the mounting work (step S401). Then, the calculation unit 61 creates a monitoring screen Gd based on the board ID, which shows the power (amount of power) consumed to perform the mounting work on board B in association with board B (serial number). With this configuration, the worker can easily compare and confirm board B, which is the target of the mounting work, with the power required to perform the mounting work on that board B.

[0086] The example of the monitoring screen displayed when an event occurs can be modified in various ways. FIG. 11F is a diagram schematically illustrating a modified example of the monitoring screen displayed when an event occurs. The monitoring screen Ge in FIG. 11F compares the maximum power consumption before and after the event of turning on the servos of the motors provided in the mounters 4A and 4B (in other words, turning on the motors). That is, the "Servo On" item shows the maximum amount of power consumed per 15 minutes by each of the mounters 4A and 4B after turning on the servos. The "Servo Off" item shows the maximum amount of power consumed per 15 minutes by each of the mounters 4A and 4B before turning on the servos.

[0087] 11F, the monitoring screen Ge compares the maximum power consumption after the occurrence of an event in which each of the mounters 4A and 4B starts mounting work. In other words, the "Maximum value during mounting work" item shows the maximum amount of power consumed per 15 minutes by each of the mounters 4A and 4B from the start to the end of mounting work.

[0088] 11A to 11F are described below as being applied to the component mounters 4A and 4B. However, the application of the control is not limited to this, and the control may be applied to any of the devices 2, 3A to 3C, 4A to 4C, and 5.

[0089] As explained above, in this embodiment, the devices 2, 3A-3C, 4A-4C, and 5 correspond to an example of the "plurality of operating units" of the present invention, the power supply system 7 corresponds to an example of the "power supply system" of the present invention, the power data 622 corresponds to an example of the "power data" of the present invention, the communication unit 64 corresponds to an example of the "data acquisition unit" of the present invention, the monitoring screens Ga, Gb, Gc, and Gd correspond to an example of the "monitoring screen" of the present invention, the display of the UI 63 corresponds to an example of the "display" of the present invention, the calculation unit 61 corresponds to an example of the "data presentation unit" of the present invention, the computer 6 corresponds to an example of the "power monitoring device" of the present invention, the memory unit 62 corresponds to an example of the "memory unit" of the present invention, the power monitoring program 621 corresponds to an example of the "power monitoring program" of the present invention, and the memory unit 62 or the external server corresponds to an example of the "recording medium" of the present invention.

[0090] The present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described embodiment without departing from the spirit of the present invention. For example, the calculation unit 61 may create and display monitoring screens Gf and Gg shown in Fig. 12 based on the power data 622. Fig. 12 is a diagram schematically illustrating a modified example of the monitoring screen.

[0091] In the power monitoring that creates the monitoring screen of Fig. 12, the calculation unit 61 acquires air consumption data from the mounters 4, which indicates the amount of air consumed (air usage) as the mounters 4 apply pressure to the nozzles. The calculation unit 61 stores the air consumption data in the storage unit 62 in association with the time of acquisition of the air consumption data. The calculation unit 61 also creates a monitoring screen Gf based on this air consumption data and power data 622, and displays it on the display of the UI 63. In the example of Fig. 12A, the monitoring screen Gf indicates the active power, apparent power, and air usage consumed by the mounters 4 for each of the two mounters 4A and 4B.

[0092] Alternatively, in parallel with the power monitoring of FIG. 9A, the calculation unit 61 may collect execution status data relating to the execution status of board production. This will be described with reference to FIG. 13. Here, FIG. 13 is a diagram schematically showing a graph representing the execution status of board production. Specifically, the calculation unit 61 monitors a dashboard displayed on the display of the UI 63. This dashboard shows information indicating the status of the devices 2, 3A to 3C, 4A to 4C, and 5, and the calculation unit 61 can acquire execution status data based on, for example, the information shown on the dashboard.

[0093] Specific execution statuses include setup, board production, emergency stop, or machine error. Setup corresponds to preparation for board production and includes supplying solder to the printer 2 and supplying components to the component mounter 4. Board production corresponds to the process (predetermined process) of producing board B on which components E are mounted by performing printing, inspection, mounting, and reflow operations on board B. An emergency stop corresponds to the stop of board production due to the stop of the printer 2 due to running out of solder or the stop of the component mounter 4 due to running out of components. A machine error corresponds to the stop of board production due to an error in equipment 2, 3A-3C, 4A-4C, or 5 that make up board production line 11.

[0094] 13 showing the change over time in the progress of board production based on the progress status data, and displays it, for example, on the monitoring screen Ga of Fig. 9C together with the change over time in the power consumed by the devices 2, 3A to 3C, 4A to 4C, and 5. In this case, the graph of Fig. 9C may be displayed separately from the graphs showing the change over time in power, or may be displayed superimposed on them.

[0095] In this embodiment, to perform board production (predetermined processing) on ​​board B (workpiece), multiple devices 2, 3A-3C, 4A-4C, and 5 (operation units) perform operations assigned to them. In response to this, a calculation unit 61 (data acquisition unit) acquires execution status data indicating the execution status of board production. Then, the calculation unit 61 (data presentation unit) creates a monitoring screen Ga indicating changes over time in the execution status of board production based on the execution status data. With this configuration, an operator can easily compare and confirm the changes over time in power with the execution status of board production on board B.

[0096] Furthermore, information about power consumption displayed on the monitoring screen may be displayed for each product configured with a board B. FIG. 14 is a diagram schematically illustrating an example of a product configured with two boards. In FIG. 14, the product is configured by stacking board B2 on board B1. In such a case, the total power consumed by operations on each of the two boards B1 and B2 that make up the product may be displayed on the monitoring screen. Using the example of FIG. 11E, if the serial numbers of boards B1 and B2 are 0001 and 0002, respectively, the total power consumed by the component mounters 4A and 4B when performing mounting operations on board B1 with serial number 0001 (20 Wh) and the total power consumed by the component mounters 4A and 4B when performing mounting operations on board B1 with serial number 0002 (24 Wh) are displayed on the monitoring screen in association with the serial numbers 0001 and 0002.

[0097] In the above example, to execute board production for board B (workpiece), multiple devices 2, 3A-3C, 4A-4C, and 5 (operation units) execute the mounting operations assigned to them. In response to this, a calculation unit 61 (data presentation unit) creates a monitoring screen that shows the power flowing into component mounters 4A and 4B (target operation units) during board production for two boards B that make up one product, in association with the one product. With this configuration, workers can easily check the power required to manufacture one product.

[0098] Furthermore, the target of power monitoring is not limited to board production line 11 shown in Figures 1A and 1B. Figure 15 is a block diagram showing another example of power monitoring. In particular, Figure 15 shows a basic power supply system that can be equipped in common to devices 2, 3A to 3C, 4A to 4C, and 5.

[0099] 15 supplies power supplied from a power distribution facility 12 to motors M1 to M4 and controllers C1 to C3 provided in the device. Specific examples of the motors M1 to M4 are the motors described above, and specific examples of the controllers C1 to C3 are the control units described above.

[0100] The power supply system 9 has a main breaker 91 connected to the power distribution facility 12, and supplies power supplied from the power distribution facility 12 to the main breaker 91 in a power supply direction Ds from the main breaker 91 to the motors M1 to M4 and the controllers C1 to C3. When the power flowing into the main breaker 91 reaches a predetermined value, the main breaker 91 cuts off the supply of power in the power supply direction Ds.

[0101] The power supply system 9 includes a transformer 92 that is provided downstream of a main breaker 91 in a power supply direction Ds and connected to the main breaker 91. The transformer 92 supplies power from the upstream side (primary side) of the transformer 92 in the power supply direction Ds to the downstream side (secondary side) of the transformer 92 in the power supply direction Ds. In other words, the transformer 92 functions as an AC power supply that supplies the power supplied from the main breaker 91 to the secondary side.

[0102] The power supply system 9 has circuit protectors 931, 932, and 933 that are provided in parallel downstream of the transformer 92 in the power supply direction Ds and connected to the transformer 92. When the power flowing into the circuit protectors 931, 932, and 933 reaches a predetermined value, each of the circuit protectors 931, 932, and 933 cuts off the supply of power in the power supply direction Ds.

[0103] A motor M1 is provided downstream of the circuit protector 931 in the power supply direction Ds, and the motor M1 is connected to the circuit protector 931. In other words, the circuit protector 931 supplies the power supplied from the transformer 92 to the motor M1, and the motor M1 operates using this power.

[0104] The power supply system 9 is provided downstream of the circuit protector 932 in the power supply direction Ds and includes a power supply 941 connected to the circuit protector 932. The power supply 941 converts the AC power supplied from the circuit protector 932 into DC power.

[0105] The power supply system 9 has circuit protectors 951, 952 that are provided in parallel downstream of the power supply 941 in the power supply direction Ds and connected to the power supply 941. When the power flowing into the circuit protectors 951, 952 reaches a predetermined value, each of the circuit protectors 951, 952 cuts off the supply of power in the power supply direction Ds.

[0106] A motor M2 is provided downstream of the circuit protector 951 in the power supply direction Ds, and the motor M2 is connected to the circuit protector 951. In other words, the circuit protector 951 supplies the power supplied from the power supply 941 to the motor M2, and the motor M2 operates using that power.

[0107] A motor M3 is provided downstream of the circuit protector 952 in the power supply direction Ds, and the motor M3 is connected to the circuit protector 952. In other words, the circuit protector 952 supplies the power supplied from the power supply 941 to the motor M3, and the motor M3 operates using that power.

[0108] The power supply system 9 has power supplies 942 and 943 that are provided in parallel downstream of the circuit protector 933 in the power supply direction Ds and connected to the circuit protector 933. The power supplies 942 and 943 convert the AC power supplied from the circuit protector 933 into DC power.
