Patent Document 1 discloses a component mounting device that includes an image signal processing circuit that displays an image signal input from a higher level on the display unit and outputs it to a lower level device, and a position signal processing circuit that transmits a position signal of the touch panel of the device to the host side when a selection switch is turned on, and transmits a position signal from the lower level to the host side when the selection switch is turned off. This allows the component mounting device to be preferentially operated from any touch panel selected from multiple touch panels connected to the host device.

[0011] First, the configuration of the mounted board manufacturing line 1 will be described with reference to FIG. 1. FIG. 1 shows a schematic diagram of the main part of the mounted board manufacturing line 1. The mounted board manufacturing line 1 is configured by connecting a plurality of component mounting devices M1 to M6 in series, and has the function of manufacturing mounted boards with components mounted on the board. In each of the component mounting devices M1 to M6, a first board transport lane L1 and a second board transport lane L2 are arranged apart in the Y-axis direction to transport the board 2 along the X-axis from upstream (upper side of the paper) to downstream (lower side of the paper). Hereinafter, in the Y-axis direction, the side where the first board transport lane L1 is arranged is referred to as the front (left side of the paper), and the side where the second board transport lane L2 is arranged is referred to as the rear (right side of the paper).

[0012] The first board transport lane L1 and the second board transport lane L2 of each of the component mounting devices M1 to M6 are connected to the adjacent devices, and transport the board 2 from upstream to downstream and deliver it to the adjacent device. Thus, each of the component mounting devices M1 to M6 is equipped with a first board transport lane L1 that transports the board 2 along the X-axis (one axis) extending horizontally, and a second board transport lane L2 that is positioned away from the first board transport lane L1 in the direction along the Y-axis (another axis perpendicular to the X-axis in the horizontal plane) and transports the board 2 along the X-axis.

[0013] 1, in each of the component mounting devices M1 to M6, a first component supply section S1 is disposed in front of the first board transport lane L1, and a second component supply section S2 is disposed behind the second board transport lane L2. Furthermore, in each of the component mounting devices M5 and M6, a third component supply section S3 is disposed downstream of the first component supply section S1, and a fourth component supply section S4 is disposed downstream of the second component supply section S2.

[0021] 1, the mounted board manufacturing line 1 includes four 2-stage / 2-head component mounting devices M1-M4 and two 4-stage / 4-head component mounting devices M5, M6, but the mounted board manufacturing line 1 is not limited to this configuration. For example, the mounted board manufacturing line 1 may be configured to include either one of the 2-stage / 2-head component mounting devices M1-M4 or the 4-stage / 4-head component mounting devices M5, M6.

[0022] Also, the system may be configured to have two, three, five or more two-stage / two-head component mounting devices M1-M4, and three or more four-stage / four-head component mounting devices M5, M6. The arrangement order of the two-stage / two-head component mounting devices M1-M4 and the four-stage / four-head component mounting devices M5, M6 can be set arbitrarily. Furthermore, the component mounting devices M1-M6 do not need to be physically connected.

[0023] Next, the detailed configuration of the two-stage / two-head component mounting devices M1-M4 will be described with reference to Figures 2 and 3. A first board transport lane L1 is arranged at the front and a second board transport lane L2 is arranged at the rear at the center of the upper part of the base 4. The first board transport lane L1 is equipped with a pair of board transport conveyors K1 for transporting the board 2. The second board transport lane L2 is equipped with a pair of board transport conveyors K2 for transporting the board 2.

[0024] A first component supply section S1 is disposed in front of the first board transport lane L1, and a second component supply section S2 is disposed behind the second board transport lane L2. A dolly 5 with a plurality of component supply units 3 (tape feeders) already attached to the upper part is set in the first component supply section S1 and the second component supply section S2. The dolly 5 holds a reel 7 that stores a carrier tape 6 holding components in a wound state. The carrier tape 6 pulled out from the reel 7 is pitch-fed by the component supply unit 3, and the components held by the carrier tape 6 are supplied to the component supply position.

[0025] 2 and 3, at both ends of the X-axis on the top surface of the base 4, a Y-axis table 8 is disposed upstream and a Y-axis support unit 9 is disposed downstream. Guide units 10 extending along the Y-axis are disposed at opposing positions on the Y-axis table 8 and the Y-axis support unit 9. A Y-axis linear motor 11 extending along the Y-axis is disposed on the Y-axis table 8. A first beam B1 is disposed in front between the Y-axis table 8 and the Y-axis support unit 9, and a second beam B2 is disposed in the rear. The first beam B1 and the second beam B2 are driven by the Y-axis linear motor 11 to move back and forth along the guide unit 10.

[0026] A first linear motor D1 extending along the X-axis is disposed on the first beam B1. A first moving member E1 driven by the first linear motor D1 and moving left and right along the X-axis is coupled to the first beam B1. A first component mounting head H1 and a first head camera C1 are attached to the first moving member E1. A second linear motor D2 extending along the X-axis is disposed on the second beam B2. A second moving member E2 driven by the second linear motor D2 and moving left and right along the X-axis is coupled to the second beam B2. A second component mounting head H2 and a second head camera C2 are attached to the second moving member E2.

[0027] 3, the first component mounting head H1 and the second component mounting head H2 are equipped with a plurality of component holding nozzles 12 that hold components at their lower ends. The first component mounting head H1 and the second component mounting head H2 raise and lower the component holding nozzles 12 along the Z axis and rotate them around the Z axis.

[0028] 2 and 3, the first component mounting head H1 moves in the horizontal direction (X-axis direction, Y-axis direction) by the Y-axis linear motor 11 and the first linear motor D1. That is, the Y-axis table 8 and the first beam B1 constitute a first work head moving mechanism F1 that moves the first component mounting head H1 and the first head camera C1 within the first area A1. The second component mounting head H2 moves in the horizontal direction by the Y-axis linear motor 11 and the second linear motor D2. That is, the Y-axis table 8 and the second beam B2 constitute a second work head moving mechanism F2 that moves the second component mounting head H2 and the second head camera C2 within the second area A2.

[0029] The first head camera C1 and the second head camera C2 move above the board 2 held at the loading work position of the first board transport lane L1 or the loading work position of the second board transport lane L2, and capture an image of a board mark (not shown) provided on the board 2. The imaged result is subjected to image recognition to identify the position of the board 2. In addition, in the first supply position teaching, which is a specific task, the first head camera C1 (first imaging section) of the first work unit U1 captures an image of the component supply unit 3 of the first component supply section S1 to detect the component supply position. In addition, in the second supply position teaching, which is a specific task, the second head camera C2 (second imaging section) of the second work unit U2 captures an image of the component supply unit 3 of the second component supply section S2 to detect the component supply position.

[0030] 2 and 3, a first component camera G1 for capturing an image of the upper side is disposed between the first component supply unit S1 and the first board transport lane L1 on the upper surface of the base 4. A second component camera G2 for capturing an image of the upper side is disposed between the second component supply unit S2 and the second board transport lane L2. When the first component mounting head H1, which has taken out a component from the first component supply unit S1, moves above the first component camera G1, the first component camera G1 captures an image of the component held by the component holding nozzle 12. When the second component mounting head H2, which has taken out a component from the second component supply unit S2, moves above the second component camera G2, the second component camera G2 captures an image of the component held by the component holding nozzle 12. The captured image is recognized, and the posture of the component held by the component holding nozzle 12 is recognized.

[0031] When the first component mounting head H1 mounts components on the board 2, the mounting positions of the components are corrected taking into account the results of board position recognition by the first head camera C1 and the results of component recognition by the first component camera G1. Similarly, when the second component mounting head H2 mounts components on the board 2, the mounting positions of the components are corrected taking into account the results of board position recognition by the second head camera C2 and the results of component recognition by the second component camera G2.

Here, a total of two first reference points J1 are arranged, one behind the first board transport lane L1 and one beside the first component camera G1. In this way, at least one first reference point J1 that serves as a reference point for the first work head moving mechanism F1 is arranged in the first area A1. In the first calibration, which is a specific work, the first reference point J1 is imaged by the first head camera C1 (first imaging unit), and the first work unit U1 is calibrated based on the position of the first reference point J1 identified from the image captured.

Here, a total of two second reference points J2 are arranged, one in front of the second board transport lane L2 and one beside the second component camera G2. In this way, at least one second reference point J2 that serves as a reference point for the second work head moving mechanism F2 is arranged in the second area A2. In the second calibration, which is a specific work, the second reference point J2 is imaged by the second head camera C2 (second imaging unit), and the second work unit U2 is calibrated based on the position of the second reference point J2 identified from the imaged image.

A control unit 20 is disposed on the base 4. In addition to the first operation unit P1 and the second operation unit P2, each unit of the component mounting devices M1 to M4 is connected to the control unit 20 (see FIG. 5). This allows a plurality of operation units (first operation unit P1 and second operation unit P2) having an input unit (touch screen 13) and a display unit (monitor 14) to communicate with the control unit 20.

[0035] The control unit 20 controls the first work unit U1 and the component supply unit 3 of the first component supply unit S1 to perform a component mounting operation to mount components on a board 2 held at the mounting operation position of the first board transport lane L1 or the mounting operation position of the second board transport lane L2.

[0048] Next, referring to Figure 5, the configuration of the control system of the two-stage / two-head component mounting device M1-M4 will be described, focusing on the function of appropriately processing operations from multiple operating parts (first operating part P1, second operating part P2) for multiple work units (first working unit U1, second working unit U2) or multiple working parts (first working part W1, second working part W2).

[0049] The control unit 20 provided in each of the component mounting devices M1 to M4 includes an input processing unit 21, a processing unit 22, an exclusive processing unit 23, an output processing unit 24, and a storage unit 25. The input processing unit 21 receives operation information from a plurality of operation units (first operation unit P1, second operation unit P2), identifies which operation unit the input came from, and outputs a command based on the operation information. The input processing unit 21 includes an input receiving unit 26, an operation unit identifying unit 27, and an output unit 28 as internal processing units.

[0050] The processing unit 22 executes various processes, which will be described later, based on commands and causes the working units (first working unit W1, second working unit W2) to perform a predetermined task (parts mounting task) and a specific task. The processing unit 22 includes, as internal processing units, a part mounting processing unit 29, a first calibration processing unit 30, a first teaching processing unit 31, a second calibration processing unit 32, and a second teaching processing unit 33. The memory unit 25 is a storage device, and stores a production program 34, teaching / calibration data 35, operation performance data 36, ​​device status data 37, etc.

[0051] 5, a first calibration processing unit 30 controls a first working unit W1 to perform a first calibration for calibrating a first working unit U1 based on the position of a first reference point J1. A second calibration processing unit 32 controls a second working unit W2 to perform a second calibration for calibrating a second working unit U2 based on the position of a second reference point J2. Information acquired by the first calibration or the second calibration (such as correction values) is stored in the memory unit 25 as teaching / calibration data 35.

[0052] The first teaching processing unit 31 controls the first working unit W1 to execute first supply position teaching, which detects the component supply position of the first component supply unit S1 and teaches the position at which the component holding nozzle 12 of the first component mounting head H1 picks up components from the component supply unit 3. The second teaching processing unit 33 controls the second working unit W2 to execute second supply position teaching, which detects the component supply position of the second component supply unit S2 and teaches the position at which the component holding nozzle 12 of the second component mounting head H2 picks up components from the component supply unit 3. Information acquired by the first supply position teaching or the second supply position teaching (such as component suction position data) is stored in the memory unit 25 as teaching / calibration data 35.

[0053] 5, production program 34 stores information and control programs required for component mounting work, such as the size of board 2, the type of components to be mounted, and mounting positions (XY coordinates) for each type of mounting board. Component mounting processing unit 29 controls first working unit W1 and second working unit W2 based on production program 34 and teaching / calibration data 35 to transport board 2 and perform component mounting work of mounting components on the board. In the component mounting work, component mounting processing unit 29 controls the positions of first component mounting head H1 and second component mounting head H2 by referring to teaching / calibration data 35 (various correction values, component suction position data, etc.).

[0054] The processing unit 22 sequentially acquires operational results such as the remaining number of components that each component supply unit 3 can supply, the number of mounting boards produced, the number of component mounting errors, and the number of pickup errors, and stores them in the memory unit 25 as operational result data 36. The processing unit 22 also sequentially acquires the states of the working units (first working unit W1, second working unit W2), the progress of the component mounting work, the progress of specific tasks such as calibration and supply position teaching, information on the operating units (first operating unit P1, second operating unit P2) that have operated the control unit 20, and stores them in the memory unit 25 as device status data 37.

[0055] 5, the first operation unit P1 is connected to a first connection port T1 provided in the control unit 20. The second operation unit P2 is connected to a second connection port T2 provided in the control unit 20. Operation events indicating the content of an operation performed by an operator on the touch screen 13 and operation information including coordinate data indicating the position where the operation was performed are transmitted to the input processing unit 21 via the connection ports (the first connection port T1 and the second connection port T2). Examples of operation events include tap, long tap, flick, slide, pen up, pen down, pitch in, pitch out, etc.

[0056] Now, referring to Fig. 6, the processing of the input receiving unit 26 will be described. The input receiving unit 26 receives operation information (operation event, coordinate data) output from the touch screen 13 (ST1). When the input receiving unit 26 receives the operation information (Yes in ST1), the input processing unit 21 determines the command input by the worker to the touch screen 13 based on the operation information received by the input receiving unit 26 (ST2). Next, the operation unit identifying unit 27 identifies from which operation unit (first operation unit P1, second operation unit P2) the operation information was transmitted (ST3). In this example, the operation unit is identified based on which connection port (first connection port T1, second connection port T2) the operation information was transmitted via.

[0057] When the first connection port T1 is identified (the first connection port in ST3), the output unit 28 outputs the operation unit identification information of the first connection port T1 in association with a command (ST4). When the second connection port T2 is identified (the second connection port in ST3), the output unit 28 outputs the operation unit identification information of the second connection port T2 in association with a command (ST5). In this way, the output unit 28 outputs to the processing unit 22 and the output processing unit 24 the command determined by the input processing unit 21 in association with the identification result (operation unit identification information) that specifies which operation unit recognized by the operation unit identification unit 27 is the operation for.

[0058] For example, when a worker taps the stop button displayed on the monitor 14 of the first operation unit P1, operation information including the operation event "tap" and coordinate data indicating the operation position on the touch screen 13 is transmitted to the control unit 20 via the first connection port T1. Based on the operation information received by the input receiving unit 26, the input processing unit 21 recognizes that the tapped position is within the display area of ​​the stop button displayed on the monitor 14 (ST2), associates the stop command with the identification result indicating the first operation unit P1 identified by the operation unit identification unit 27, and outputs the association result to the processing unit 22 and the output processing unit 24 (ST4).

[0059] In this way, the input processing unit 21 receives operation information from a plurality of operation units (first operation unit P1, second operation unit P2), identifies which operation unit the input came from, and outputs a command based on the operation information. The plurality of operation units are individually connected to a plurality of connection ports (first connection port T1, second connection port T2) provided in the control unit 20, and the input processing unit 21 detects which connection port the operation information passed through and identifies the operation unit that output the operation information.

[0060] 5, the exclusion processing unit 23 executes exclusion processing to permit operations from the operation unit that instructed the specific work at a work unit while prohibiting operations from other operation units, based on the identification result of the operation unit output from the input processing unit 21 and the status of the work units (first work unit W1, second work unit W2) included in the device status data 37. This makes it possible to prevent operations from other operation units that conflict with the work unit where the specific work is being performed.

[0061] For example, when the first operating part P1 is operated to perform a specific task, calibration, on the first working part W1 (or the first working unit U1), while the first calibration processing part 30 is causing the first working part W1 to perform the first calibration, the exclusive processing part 23 permits operation from the first operating part P1 but prohibits operation from the second operating part P2.

[0062] That is, the exclusive processing unit 23 refers to the identification result of the operation unit by the input processing unit 21, and when one operation unit (first operation unit P1) is assigned to one working unit in order to have one working unit (first working unit W1) or one working unit (first working unit U1) execute a specific task (calibration), the exclusive processing unit 23 permits the one operation unit to perform operations for the one working unit but prohibits the other operation unit (second operation unit P2) from performing operations for the other working unit (second working unit W2) or other working unit (second working unit U2) and permits the other operation unit to perform operations for the other working unit (second working unit W2) or other working unit (second working unit U2). This makes it possible to appropriately perform operations from each operation unit even when operations are simultaneously performed from multiple operation units on multiple working units or working units.

[0063] 5, the output processing unit 24 displays the execution result of the command executed by the processing unit 22 on the monitor 14 of the specified operation unit (first operation unit P1, second operation unit P2) based on the identification result of the operation unit specified by the input processing unit 21. For example, when the first working unit W1 is performing calibration by operation from the first operation unit P1, the output processing unit 24 displays the execution result including the progress of the calibration in the first working unit W1 on the monitor 14 of the first operation unit P1. In other words, the output processing unit 24 displays the execution result of the command on the display unit (monitor 14) of the operation unit specified by the identification by the input processing unit 21.

[0064] Next, examples of monitor screens displayed on the monitor 14 of the first operation unit P1 and the monitor 14 of the second operation unit P2 of each of the component mounting devices M1 to M4 will be described with reference to FIGS.

[0065] 7 shows a state in which the first working unit W1 and the second working unit W2 of each of the component mounting devices M1 to M4 are performing component mounting work on different types of mounting boards, and neither the first operation unit P1 nor the second operation unit P2 has been operated for a predetermined time (e.g., 5 minutes) or more. That is, based on the device status data 37, the output processing unit 24 causes the monitor 14 of the first operation unit P1 and the monitor 14 of the second operation unit P2 to display, respectively, the positions of the boards 2 being transported in the first board transport lane L1 and the second board transport lane L2, the board type of the mounting board being produced, the number of boards 2 on which the component mounting work has been completed, and the number of boards 2 for which production is planned.

[0066] Furthermore, the output processing unit 24 causes the monitor 14 of the first operation unit P1 to display information relating to the first board transport lane L1 on the lower side, and causes the monitor 14 of the second operation unit P2 to display information relating to the second board transport lane L2 on the lower side. That is, on each monitor 14, the board transport lane on the near side as viewed from the monitor 14 is displayed on the lower side. This allows an operator looking at the monitor 14 to easily grasp the status inside the component mounting devices M1-M4.

[0067] State B of FIG. 7 shows a state after the operator touches the monitor 14 of the first operation unit P1 in state A (tap anywhere on the screen). When the operator touches the monitor 14 of the first operation unit P1, operation information (tap, tapped coordinates) is output from the touch screen 13 of the first operation unit P1. The input processing unit 21 (operation unit identification unit 27) detects that the operation information has passed through the first connection port T1 and identifies that it is the first operation unit P1 that has output the operation information. The output processing unit 24 displays a main menu for receiving commands on the monitor 14 of the first operation unit P1. That is, the output processing unit 24 displays the execution result of the command (main menu display) on the monitor 14 of the first operation unit P1 specified by the identification by the input processing unit 21.

[0068] Furthermore, the output processing unit 24 causes the monitor 14 of the second operation unit P2 to display a notification indicating that an operation has been performed at the first operation unit P1. In this example, the notification is made by changing the color of the border of the screen displayed on the monitor 14. Note that the notification method is not limited to changing the color of the border of the screen, and it is also possible to change the color of the entire screen, or to display a comment on the screen indicating that an operation has been performed at the first operation unit P1.

[0069] State C in FIG. 7 shows the state after the worker selects the "Display remaining parts number" button (tap inside the display area of ​​the "Display remaining parts number" button) from the main menu displayed on the monitor 14 of the first operation unit P1 in state B. When the worker selects the "Display remaining parts number" button, operation information (tap, tapped coordinates) is output from the touch screen 13 of the first operation unit P1. The output processing unit 24 displays a screen showing the remaining parts number on the monitor 14 of the first operation unit P1 based on the remaining number of parts that each component supply unit 3 can supply, which is included in the operation performance data 36. It should be noted that the output processing unit 24 does not change the display on the monitor 14 of the second operation unit P2.

[0070] State D in FIG. 7 shows a state after the operator selects the "Operation History Data (Suction Nozzle)" button from the main menu displayed by touching the monitor 14 of the second operation unit P2 in state C. That is, the output processing unit 24 displays a screen showing the operation history on the monitor 14 of the second operation unit P2 based on the operation history data of the component holding nozzle 12 included in the operation history data 36. Furthermore, the output processing unit 24 displays a notice indicating that an operation has been performed on the second operation unit P2 on the monitor 14 of the first operation unit P1. Note that the output processing unit 24 does not change the display on the monitor 14 of the first operation unit P1.

[0071] State E in Fig. 8 shows a state after the operator selects the "calibration" button from the main menu displayed on monitor 14 of first operation unit P1 when both first working unit W1 and second working unit W2 are capable of performing a specific task. In other words, neither first working unit W1 nor second working unit W2 is performing a component mounting task, and no information related to the component mounting task is displayed on monitor 14 of second operation unit P2.

[0072] When the "Calibration" button is selected, the output processing unit 24 displays a calibration selection menu on the monitor 14 of the first operation unit P1. The calibration selection menu displays a "Front" button and a "Back" button for selecting the working unit on which the calibration is to be performed, as well as a "Start" button and a diagram that shows a schematic representation of the working units of the component mounting devices M1 to M4.

[0073] State F of FIG. 8 shows a state after the operator taps the "Start" button in a state in which the operator has tapped the "Front" button (working unit selection button) to select the front in the calibration selection menu displayed on the monitor 14 of the first operation unit P1 in state E. That is, the first calibration processing unit 30 causes the first working unit W1 to perform the first calibration based on the operation information output from the touch screen 13 of the first operation unit P1. The output processing unit 24 causes the monitor 14 of the first operation unit P1 to display a calibration status screen. The calibration status screen displays a diagram that shows in schematic form that the calibration is being performed on the first working unit W1, characters and a graph showing the progress of the calibration (here, 5%), and a "Stop" button.

[0074] Furthermore, the output processing unit 24 causes the monitor 14 of the second operation unit P2 to display a message indicating that calibration is being performed in the first working unit W1. In this example, text information "Calibration in progress" is displayed at a position indicating the first board transport lane L1. The exclusion processing unit 23 assigns the first operation unit P1 to the first working unit W1 based on the operation information output from the touch screen 13 of the first operation unit P1, and then maintains that state until the first calibration is completed.

[0075] That is, the exclusion processing unit 23 permits the first operation unit P1 to operate the first working unit W1 but prohibits the second operation unit P2 from operating the first working unit W1 until the first calibration is completed. Therefore, a "Stop" button for stopping the calibration of the first working unit W1 is displayed on the monitor 14 of the first operation unit P1, but no buttons or the like for operating the first working unit W1 are displayed on the monitor 14 of the second operation unit P2. When the "Stop" button displayed on the monitor 14 of the first operation unit P1 is operated, the calibration of the first working unit W1 is stopped.

[0076] State G of Fig. 8 shows a state after the operator selects the "Teaching" button from the main menu displayed by touching monitor 14 of second operation unit P2 in state F. That is, in a state in which exclusion processing unit 23 assigns first operation unit P1 to first working unit W1, output processing unit 24 displays a teaching selection menu on monitor 14 of second operation unit P2. In the teaching selection menu, a "Front" button and a "Back" button for selecting a working unit to perform calibration, a "Start" button, and a diagram that typically displays the working units of component mounting devices M1 to M4 are displayed.

[0077] The first calibration is being performed in the first working unit W1, and the second operation unit P2 is prohibited from performing operations for the first working unit W1. Therefore, the output processing unit 24 displays the "Back" button in the teaching selection menu in an inoperable state. Also, in the schematic diagram, the first working unit W1 is displayed with a dotted line to clearly indicate that it cannot be selected. Also, the output processing unit 24 updates the progress of the calibration (here, 10%) displayed on the monitor 14 of the first operation unit P1 to the latest status.

[0078] State H of FIG. 8 shows a state after the operator taps the "Start" button in the teaching selection menu displayed on the monitor 14 of the second operation unit P2 in state G, in which the operator has tapped the "Front" button to select "Front." That is, based on the operation information output from the touch screen 13 of the second operation unit P2, the second teaching processing unit 33 causes the second working unit W2 to perform the second supply position teaching. The output processing unit 24 causes the monitor 14 of the second operation unit P2 to display a teaching status screen. The teaching status screen displays a diagram that shows in schematic form that the supply position teaching is being performed on the second working unit W2, characters and a graph showing the progress of the teaching (here, 0%), and a "Stop" button.

[0079] Furthermore, the output processing unit 24 updates the progress of the calibration (here, 20%) displayed on the monitor 14 of the first operation unit P1 to the latest progress. The exclusion processing unit 23 assigns the second operation unit P2 to the second working unit W2 based on the operation information output from the touch screen 13 of the second operation unit P2, and maintains this state until the second supply position teaching is completed. In other words, the exclusion processing unit 23 permits the second operation unit P2 to operate the second working unit W2 but prohibits the first operation unit P1 from doing so until the second supply position teaching is completed.

[0080] Therefore, a "Stop" button for stopping the supply position teaching of the second working unit W2 is displayed on the monitor 14 of the second operation unit P2, but no buttons or the like for operating the second working unit W2 are displayed on the monitor 14 of the first operation unit P1. When the "Stop" button displayed on the monitor 14 of the second operation unit P2 is operated, the component supply position teaching of the second working unit W2 is stopped.

[0081] 9 shows a state after a worker selects the "Calibration" button from the main menu displayed on the monitor 14 of the first operation unit P1 and another worker selects the "Calibration" button from the main menu displayed on the monitor 14 of the second operation unit P2 in a state in which both the first working unit W1 and the second working unit W2 are capable of performing a specific task. That is, the output processing unit 24 causes the monitor 14 of the first operation unit P1 to display a calibration selection menu, and also causes the monitor 14 of the second operation unit P2 to display a calibration selection menu.

[0082] 9 shows a state after a worker taps the "Front" button on monitor 14 of first operation unit P1 to select the front (first working unit W1) in state K, and another worker taps the "Front" button on monitor 14 of second operation unit P2 to select the front (second working unit W2). That is, exclusive processing unit 23 assigns first operation unit P1 to first working unit W1, and assigns second operation unit P2 to second working unit W2.

[0083] The exclusive processing unit 23 permits the first operation unit P1 to operate the first working unit W1 but prohibits the second operation unit P2 from operating the second working unit W2, and permits the second operation unit P2 to operate the second working unit W2 but prohibits the first operation unit P1 from operating the second working unit W2. The output processing unit 24 displays the "deep" button for operating the second working unit W2 on the monitor 14 of the first operation unit P1 in an inoperable state, and displays the "deep" button for operating the first working unit W1 on the monitor 14 of the second operation unit P2 in an inoperable state.

[0084] State M in Fig. 9 shows a state after an operator taps the "Start" button on the monitor 14 of the first operation unit P1 in state L, and another operator taps the "Start" button on the monitor 14 of the second operation unit P2. That is, the first calibration is performed by the first calibration processing unit 30, and the second calibration is performed by the second calibration processing unit 32. Then, the output processing unit 24 causes the monitor 14 of the first operation unit P1 to display a calibration status screen for the first working unit W1, and causes the monitor 14 of the second operation unit P2 to display a calibration status screen for the second working unit W2.

[0085] A "Stop" button for stopping the calibration of the first working unit W1 is displayed on the monitor 14 of the first operation unit P1. Also, a "Stop" button for stopping the calibration of the second working unit W2 is displayed on the monitor 14 of the second operation unit P2. That is, an exclusive state is established in which operations for the first working unit W1 are permitted from the first operation unit P1, but operations for the second working unit W2 are not permitted (prohibited). Similarly, an exclusive state is established in which operations for the second working unit W2 are permitted from the second operation unit P2, but operations for the first working unit W1 are not permitted (prohibited).

[0086] Next, a first modified example of component mounting devices M1 to M4 will be described with reference to Fig. 10(a) and Fig. 10(b). The first modified example differs from component mounting devices M1 to M4 shown in Fig. 5 in that unique operation unit identification information 15 is set for first operation unit P1 and second operation unit P2, respectively. The differences from component mounting devices M1 to M4 shown in Fig. 5 will be described below. When outputting operation information to control unit 20, first operation unit P1 and second operation unit P2 output the operation unit identification information 15 set therein. Input receiving unit 26 receives the operation information and operation unit identification information 15 (Yes in ST11).

[0087] Next, the input processing unit 21 determines the command input to the touch screen 13 based on the operation information (ST12). Next, the output unit 28 outputs the determined command in association with the received operation unit identification information 15 or the identification result by the operation unit identification unit 27 (ST13). In this way, unique operation unit identification information 15 is set for multiple operation units, and the input processing unit 21 identifies the operation unit that output the operation information based on the operation unit identification information 15 received together with the operation information. This makes it possible to correctly identify the operation unit that output the operation information even if the first operation unit P1 is mistakenly connected to the second connection port T2.

[0088] Next, a second modified example of the component mounting devices M1 to M4 will be described with reference to FIG. 11. The second modified example differs from the first modified example in that the first operation unit P1 and the second operation unit P2 and the control unit 20 transmit and receive information wirelessly. The differences from the first embodiment will be described below. The first operation unit P1 and the second operation unit P2 each include an operation unit side communication unit 16. The control unit 20 includes a control unit side communication unit 38. The operation unit side communication unit 16 and the control unit side communication unit 38 transmit and receive various information wirelessly. That is, the operation information and operation unit identification information 15 output from the first operation unit P1 are transmitted wirelessly from the operation unit side communication unit 16 to the control unit 20 via the control unit side communication unit 38.

[0089] Moreover, the execution result to be displayed on the monitor 14 of the operation unit output from the output processing unit 24 is wirelessly transmitted from the control unit side communication unit 38 to the operation unit side communication unit 16 of the operation unit (first operation unit P1 or second operation unit P2) specified by the identification result. This allows an operator carrying the first operation unit P1 or the second operation unit P2 to appropriately operate the multiple work units (working units) of the component mounting devices M1 to M4 from a position away from the component mounting devices M1 to M4. Note that instead of the control unit side communication unit 38, an access point capable of wirelessly communicating with the operation unit side communication unit 16 may be installed in the factory where the component mounting devices M1 to M4 are arranged, and the access point and the control unit 20 of the component mounting devices M1 to M4 may be connected by a wired communication network.

[0090] As described above, component mounting devices M1-M4 (working devices) of this embodiment include a control unit 20 that causes a first working unit U1 and a second working unit U2 (first working unit W1, second working unit W2) to perform a component mounting task (predetermined task) of mounting components on a board 2 and a specific task, and multiple operation units (first operation unit P1, second operation unit P2) connected to the control unit 20. The control unit 20 also includes an input processing unit 21, a processing unit 22, an exclusive processing unit 23, and an output processing unit 24. This allows appropriate operation from each operation unit even when operations are simultaneously performed from multiple operation units on multiple work units or working units.

[0091] Although the above describes the configuration of the control system of the two-stage / two-head component mounting devices M1-M4, the configuration of the control system of the four-stage / four-head component mounting devices M5, M6 is similar. That is, the component mounting devices M5, M6 (working devices) are equipped with a control unit 20 that causes the first working unit U1 (first working section W1), the second working unit U2 (second working section W2), the third working unit U3 (third working section W3), and the fourth working unit U4 (fourth working section W4) to perform a component mounting task (predetermined task) of mounting components on the board 2 and a specific task, and a plurality of operation units (first operation unit P1, second operation unit P2) connected to the control unit 20.

[0092] The control unit 20 has an input processing unit 21, a processing unit 22, an exclusive processing unit 23, and an output processing unit 24. This allows appropriate operations to be performed from multiple operation units (first operation unit P1, second operation unit P2) on multiple task units (first task unit U1, second task unit U2, third task unit U3, fourth task unit U4). [Industrial Applicability]
