Here, an example of an operation screen of the processing device MP for remote operation, which is displayed on the display unit 38 of the management computer 3, will be described with reference to FIG. In FIG. 4, the display screen 51 of the display unit 38 displays an operation screen 52 for remotely operating the component mounting apparatus M5 on the component mounting line L1. A screen display frame 53 and various remote operation switches S are displayed on the operation screen 52 . In the upper left part of the screen display frame 53, characters 53a (here, "L1-M5") are displayed to specify the processing device MP to be remotely operated. In a screen display area 53b within the screen display frame 53, the same screen information as that displayed on the touch panel 6 (see FIG. 2) of the component mounting apparatus M5 is displayed.

The remote operation switches S include a remote start switch S1, a remote stop switch S2, and a remote acquisition switch S3. Each remote operation switch S corresponds to each operation button B of the component mounting apparatus M5. That is, when the remote start switch S1 displayed on the operation screen 52 is operated by the input unit 37 of the management computer 3, the same operation as when the start button B1 is operated on the component mounting apparatus M5 is executed. Similarly, when the remote stop switch S2 is operated, the same operation as when the stop button B2 is operated is performed, and when the remote acquisition switch S3 is operated, the same operation as when the acquisition button B3 is operated is performed. Executed in device M5.

The remote operator operates the operation screen of the component mounting apparatus M5 displayed on the operation screen 52 of the management computer 3 and each remote operation switch S using the input section 37 (input section) of the management computer 3 (management device). can be used to remotely operate the component mounting apparatus M5 (processing apparatus MP). As described above, the component mounting system 1 includes a component mounting line L1 configured by connecting a plurality of processing devices MP, and a management device (management computer 3) connected to the component mounting line L1 via a network (management network 2). An input unit (input unit 37) provided in the management device can be used to remotely operate the plurality of processing devices MP via a network.

In FIG. 3, the error type determination unit 33 determines whether the device error of each processing device MP stored in the error information 31a is a remote error ER or an on-site error EL. Determine the type of device error (error). A remote handling error ER is a device error that can be handled by a remote operator through remote operation using the management computer 3 . The on-site response error EL is an equipment error that can be dealt with only by the on-site operation of the processing equipment MP by the on-site worker. Those with That is, the error type determination unit 33 determines whether or not the device error (error) occurring in the processing device MP is a remote error ER, which is an error to be addressed by remote operation by the management computer 3 (management device).

The remote error ER that occurs in the component mounting apparatuses M5 to M8 includes a board misalignment error captured and recognized by a board recognition camera, a component recognition error captured by a component recognition camera, and the like. A remote error ER that occurs in the solder post-printing inspection device M3 includes a solder inspection error captured and recognized by a solder inspection camera. The remote error ER that occurs in the post-mounting inspection apparatus M10 includes a mounting inspection error that is captured and recognized by a component inspection camera. These remote handling errors ER are captured by each camera and displayed on the display unit 38 of the management computer 3 in the same image as the image captured by each camera and displayed on the display unit 26 of each processing device MP. By performing an appropriate remote operation, it is possible to eliminate the remote response error ER.

The on-site error EL that occurs in the component mounters M5 to M8 includes an error that the tape feeder 8 runs out of components. On-site error EL also includes apparatus errors that are once determined as remote-response errors ER and are changed to on-site response errors EL by the judgment of the remote operator. For example, the component recognition error, which is the remote response error ER, is detected by the remote operator who saw the image displayed on the display unit 38 of the management computer 3, and the components are not held by the suction nozzles and the component mounters M5 to M8 There is a possibility that a part may have been dropped inside, and it may be determined as a part drop error requiring on-site work and changed to an on-site response error EL.

In FIG. 3 , the operation authority setting unit 34 updates the operation authority information 31 b of the management computer 3 and the operation authority information 22 b of the processing device MP based on the type of device error determined by the error type determination unit 33 . Specifically, when the device error determined by the error type determination unit 33 is the remote error ER, the operation authority setting unit 34 sets and manages the remote operation authority RR by the management computer 3 for the processing device MP. The operating right information 31b of the computer 3 and the operating right information 22b of the processing device MP are updated.

That is, the operation authority setting unit 34 sends the remote operation authority RR to the management computer 3 (management device) to enable remote operation of the processing device MP by the input unit 37 (input unit) of the management computer 3 (management device). If the error determined by the error type determination unit 33 is the remote error ER, the remote operation right RR is set for the management computer 3 (management device).

Further, when the device error determined by the error type determination unit 33 is the on-site error EL, the operation authority setting unit 34 cancels the remote operation authority RR by the management computer 3 for the processing device MP. Then, the operating right setting unit 34 sets the local operating right RL to the processing device MP and updates the operating right information 31b of the management computer 3 and the operating right information 22b of the processing device MP.

Further, the operation right setting unit 34 operates the input unit 25 of the processing device MP by operating the acquisition button B3 of the processing device MP in a state where the remote operation right RR is set for the management computer 3 (management device). When there is a request for operation (on-site operation) by (input unit), the remote operation right RR set for the management computer 3 (management device) is canceled. Then, the operating right setting unit 34 sets the local operating right RL to the processing device MP and updates the operating right information 31b of the management computer 3 and the operating right information 22b of the processing device MP.

Further, the operation right setting unit 34 allows the device monitoring unit 23 of the processing device MP to perform a predetermined identification for the processing device MP in a state where the remote operation right RR is set for the management computer 3 (management device). When it detects that an action has been performed, it cancels the remote operation right RR set for the management computer 3 (management device). Then, the operating right setting unit 34 sets the local operating right RL to the processing device MP and updates the operating right information 31b of the management computer 3 and the operating right information 22b of the processing device MP.

In FIG. 3 , the operation monitoring unit 35 monitors the idle time TA during which the remote operator does not perform the remote operation of the processing device MP using the management computer 3 while the management computer 3 is set with the remote operation right RR. That is, the elapsed time from the last remote operation is measured and monitored. When the idle time TA exceeds a predetermined time, the operation authority setting section 34 cancels the remote operation authority RR set for the processing device MP. That is, the operation authority setting unit 34 cancels the remote operation authority RR when the remote operation by the management computer 3 (management device) is not performed within a predetermined time (predetermined idle time TA). Then, the operating right setting unit 34 sets the local operating right RL to the processing device MP and updates the operating right information 31b of the management computer 3 and the operating right information 22b of the processing device MP.

The management-side notification control unit 36 instructs the device-side notification control unit 24 of the processing device MP to transmit a predetermined notification pattern based on the device error determined by the error type determination unit 33, and also controls the management buzzer 39 of the management computer 3. And it controls the notification operation by the display unit 38 . The management side notification control unit 36 controls the management buzzer 39 (third notification unit) to perform notification by sound. Note that the management computer 3 may be provided with a chime, siren, or the like as a third notification section (management device side notification section) as long as it can notify by sound.

The management-side notification control unit 36 also controls the display unit 38 (fourth notification unit) to perform notification by visual expression such as blinking the entire display screen 51 of the display unit 38 or a part thereof. The management computer 3 may be provided with a signal tower, a revolving lamp, a flash lamp, or the like as a fourth notification unit (management device side notification unit) as long as it can be notified by visual expression.

Specifically, when the error type determination unit 33 determines that the device error is the remote error ER, the management side notification control unit 36 sends the first notification pattern to the processing device in which the device error occurred. The device side notification control unit 24 of the MP is instructed. The management-side notification control unit 36 performs notification by the management buzzer 39 (third notification unit) and the display unit 38 (fourth notification unit).

When the error type determination unit 33 determines that the device error is not the remote error ER but the on-site error EL, the management-side notification control unit 36 sets the second notification pattern to the process in which the device error occurred. The device-side notification control unit 24 of the device MP is instructed. Then, the management-side notification control unit 36 does not notify the management buzzer 39 (third notification unit) and the display unit 38 (fourth notification unit).

In this way, the device buzzer 4 (first reporting unit) and signal tower 5 (second reporting unit) of the processing device MP, the management buzzer 39 (second reporting unit) and the display unit 38 (fourth reporting unit) of the management computer 3 ) serves as a notification unit AM for notifying the occurrence of an error in the processing device MP based on the determination result of the error type determination unit 33 . Then, if the error occurring in the processing device MP is the remote error ER, the notification unit AM notifies with the first notification pattern, and if the error is the field error EL and not the remote error ER, the second notification pattern Notify by pattern.

That is, the notification unit AM is provided in each of the processing devices MP, and includes at least a first notification unit (apparatus buzzer 4) that performs notification by sound and a second notification unit (signal tower 5) that performs notification by visual expression. In addition, in the first notification pattern, notification is performed by the second notification unit without notification by the first notification unit, and in the second notification pattern, notification is performed by the first notification unit and the second notification unit, respectively.

The notification unit AM is provided in the management device (management computer 3) and includes a third notification unit (management buzzer 39) that performs notification by sound and a fourth notification unit (display unit 38) that performs notification by visual expression. Further, in the first notification pattern, the third notification unit and the fourth notification unit respectively perform notification, and in the second notification pattern, neither the third notification unit nor the fourth notification unit performs the notification.

A first embodiment of will be described. The first embodiment of the system operation method is an appropriate notification control method in response to device errors. When the device monitoring unit 23 of the processing device MP detects a device error, the error type determination unit 33 of the management computer 3 determines whether the device error is a remote error ER (ST1: error type determination step). That is, the error type determination unit 33 determines whether or not the device error that has occurred in the processing device MP is a remote error ER, which is a target device error to be addressed by remote operation by the management device (management computer 3).

If the type of device error is a remote error ER (Yes in ST1), the notification unit AM notifies with a first notification pattern (ST2: first notification step). Specifically, the notification unit AM performs notification by the signal tower 5 (second notification unit) without performing notification by the device buzzer 4 (first notification unit) of the processing device MP. 39 (third notification unit) and display unit 38 (fourth notification unit) perform notification. That is, in the first notification pattern, the processing device MP does not perform notification by sound, but performs notification by visual expression, and the management computer 3 (management device) performs notification by sound and notification by visual expression.

If the type of device error is an on-site error EL and not a remote error ER (No in ST1), the notification unit AM notifies with a second notification pattern (ST3: second notification step). Specifically, the notification unit AM performs notification by the device buzzer 4 (first notification unit) and the signal tower 5 (second notification unit) of the processing device MP, but the management buzzer 39 (third notification unit) of the management computer 3 section) and the display section 38 (fourth notification section) do not perform notification.

That is, in the second notification pattern, the processing device MP performs notification by sound and notification by visual expression, and the management computer 3 (management device) performs neither notification by sound nor notification by visual expression. In addition, as the second notification pattern, it is also possible to perform notification only by visual representation without performing notification by sound. This also allows the remote operator to appropriately recognize that the on-site error EL has occurred instead of the remote error ER.

Thus, based on the determination result of the type of device error in the error type determination step (ST1), if the type of the device error is the remote error ER, the notification unit AM notifies with the first notification pattern and the type of the device error. is not a remote error ER, the second notification pattern is used for notification.

When the device error is notified in the first notification step (ST2), the remote operator who notices the notification in the management computer 3 then remotely operates the processing device MP in which the device error has occurred (ST4: remote operation process). Next, it is determined whether or not the device error of the processing device MP has been resolved by remote operation by the remote operator (ST5: error resolution determination step). That is, the error type determination unit 33 determines whether or not the device error of the processing device MP has been resolved and the device error has disappeared from the error information 31a stored in the management storage unit 31 .

If it is determined in the error resolution determination step (ST5) that the device error has not been resolved (No), the process proceeds to the second notification step (ST3) to perform notification in the second pattern. That is, the device error is a remote error ER, and after the management device (management computer 3) has notified in the first notification pattern, the device error has not been resolved even after the remote operation by the management device has ended. In this case, the processing device MP notifies with the second notification pattern. In other words, if the device error is a remote error ER and the device error has not been resolved even after the remote operation by the management device has ended after the device error has been reported in the first reporting pattern, the device error is not resolved in the second reporting pattern. to notify you. As a result, even if the device error cannot be resolved by the remote operation by the remote operator, it is possible to appropriately perform the notification to prompt the on-site operator to perform the on-site operation.

When the device error is notified in the second notification step (ST3), the field worker who notices the notification in the processing device MP performs the field operation on the processing device MP in which the device error occurred (ST6: field operation step ). As a result, even if the device error cannot be resolved by the remote operation by the remote worker, the device error can be appropriately resolved by the on-site operation by the on-site worker.

As described above, in the component mounting system 1, it is determined whether or not the device error that has occurred in the processing device MP is the remote-compatible error ER. If the apparatus error is not the remote error ER, the second notification pattern is used. As a result, the on-site worker or the remote worker who should deal with the device error in the processing device MP constituting the component mounting line L1 is appropriately notified, and the on-site operation by the on-site worker and the remote operation by the remote worker are properly operated. can do.

Next, in accordance with the flow of FIG. 6, a component mounting method in the component mounting system 1, which is a system operation method for appropriately operating the management computer 3 and the processing device MP in response to a device error that has occurred in the processing device MP. A second embodiment will be described. The second embodiment of the system operation method differs from the first embodiment in that the notification pattern is determined depending on the presence or absence of the local operation right RL of the processing device MP when the device error is detected. Hereinafter, the same steps as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

When the device monitoring unit 23 of the processing device MP detects a device error, the error type determination unit 33 of the management computer 3 determines whether the device error is a remote error ER (ST1: error type determination step). If the device error type is a remote error ER (Yes in ST1), the management-side notification control unit 36 refers to the operation right information 31b stored in the management storage unit 31, and sets the local operation right RL to the processing device MP. is determined (ST11: field operation right determination step).

If the local operation right RL is not set for the processing device MP (No in ST11), the notification unit AM notifies in the first notification pattern (ST2: first notification step). When the local operation right RL is set for the processing device MP (Yes in ST11), the notification unit AM notifies in the second notification pattern (ST3: second notification step). That is, when the device error is the remote error ER, and when the input unit (input unit 25) provided in the processing device MP is in the operating state when the device error occurs, the notification unit AM uses the second notification pattern. inform.

If it is determined in the error type determination step (ST1) that the type of device error is not the remote error ER (No), the notification unit AM notifies in the second notification pattern (ST3: second notification step). When the device error is notified in the first notification step (ST2), the remote operator then remotely operates the processing device MP (ST4: remote operation step).

Next, it is determined whether or not the device error of the processing device MP has been resolved by remote operation (ST5: error resolution determination step). If it is determined in the error resolution determination step (ST5) that the device error has not been resolved (No), the process proceeds to the second notification step (ST3) to perform notification in the second pattern. When the apparatus error is notified in the second notification step (ST3), the site operator then performs the on-site operation of the processing apparatus MP (ST6: on-site operation step).

As described above, in the component mounting system 1, it is determined whether or not the device error that has occurred in the processing device MP is the remote-compatible error ER. If the apparatus error is not the remote error ER, the second notification pattern is used. Then, when the device error is a remote error ER and when the input unit (input unit 25) provided in the processing device MP is in an operating state when the device error occurs, the notification unit AM outputs the second notification pattern. I am reporting.

That is, even if the device error is a remote response error ER, if the processing device MP is being operated on-site, the remote worker is not notified and the on-site worker is notified to respond by the on-site operation. is doing. As a result, the on-site worker or the remote worker who should deal with the device error in the processing device MP constituting the component mounting line L1 is appropriately notified, and the on-site operation by the on-site worker and the remote operation by the remote worker are properly operated. can do.

That is, when the type of the device error is the remote error ER, the operation authority setting unit 34 can remotely operate the processing device MP with respect to the management device (management computer 3) using the input unit (input unit 37) provided in the management device. A remote operation right RR is set.

Next, in a state where the remote operation right RR is set for the management computer 3 by the remote operation right setting step (ST21), when the acquisition button B3 of the processing device MP is operated to request the local operation right RL (ST22 Yes), the operating authority setting section 34 cancels the remote operating authority RR (ST23: remote operating authority canceling step). In other words, the operation right setting unit 34 sets the remote operation right RR to the management device (management computer 3) to enable the remote operation of the processing device MP by the input unit (input unit 37) of the management device (management computer 3). Then, in a state where the remote operation right RR is set for the management device, if there is an operation request from the input unit (input unit 25) provided in the processing device MP, the remote operation set for the management device is requested. Release the right RR.

Next, the operating authority setting unit 34 sets the local operating authority RL for the processing device MP (ST24: local operating authority setting step). In this way, even after the device error is determined to be a remote error ER and the remote operation right RR is once set, the remote operation right RR is canceled when the field worker requests the on-site operation right RL. A field operation right RL is set. As a result, the on-site operation by the on-site worker and the remote operation by the remote worker can be properly operated.

When it is detected that the period has elapsed (Yes in ST31), the operation authority setting unit 34 cancels the remote operation authority RR (ST23: remote operation authority cancellation step). That is, in a state where the remote operation right RR is set for the management computer 3, the operation right setting unit 34 sets the remote operation if the remote operation by the management device (management computer 3) is not performed for a predetermined time. Release the operation right RR.

Next, the operating authority setting unit 34 sets the local operating authority RL for the processing device MP (ST24: local operating authority setting step). In this way, even after the device error is determined to be a remote error ER and the remote operation right RR is once set, if the remote operator does not perform the remote operation for a predetermined period of time, the remote operation right is granted. RR is released and local operation right RL is set. As a result, the on-site operation by the on-site worker and the remote operation by the remote worker can be properly operated. If it is determined in the error type determination step (ST1) that the type of device error is not the remote error ER (No), the process proceeds to the local operation right setting step (ST24), where the local operation right RL is assigned to the processing device MP. set.
