  Each of the production facilities 2 to 4 includes control devices 21, 31, and 41, detection units 22, 32, and 42, and display units 23, 33, and 43, respectively. Here, each control apparatus 21,31,41, each detection part 22,32,42 and each display part 23,33,43 are the structures substantially the same in each production equipment 2-4. Therefore, in order to simplify the description, here, the production equipment is the component mounter 3, and the control device 31, the detection unit 32, and the display unit 33 provided in the component mounter 3 will be described.

  The control device 31 is a device that executes various control processes, and is connected to the host computer 5 so as to be communicable. The control device 31 inputs signals output from various sensors provided in the component mounter 3 and image data from a camera. Then, the control device 31 uses the component mounter 3 so that the electronic components are appropriately mounted on the printed circuit board based on a preset control program, signals from various sensors, image processing results for the image data, and the like. Controls each axis motor and each device.

  The detection unit 32 detects an error that has occurred in the component mounter 3. More specifically, the detection unit 32 inputs signals from various sensors arranged in the component mounter 3 and processing results when the component mounter 3 determines whether the mounting is appropriate by image processing. And the detection part 32 detects the error which generate | occur | produced in the component mounting machine 3 based on said signal and a processing result. In addition, when detecting an error, the detection unit 32 sends the detection result to the host computer 5 via the control device 31.

  The display unit 33 is provided in the component mounter 3 and displays the detection result by the detection unit 32. In the present embodiment, as shown in FIG. 2, the display unit 33 is configured by a monitor M of an operating device that receives an input operation by an operator or administrator in the component mounter 3 and a plurality of notification lamps Le <b> 1 to Le <b> 3. The display unit 33 displays the operation status of the component mounter 3 and the presence / absence of errors. The display unit 33 is controlled by the control device 31 and the host computer 5 to display contents. Further, the notification lamps Le1 to Le3 constituting the display unit 33 are given different colors such as green, yellow, and red, and are turned on or off by the control device 31 according to the type and level of the error that has occurred in the component mounter 3. Controlled to blink.

  Here, the “operator” is a person who operates the production facility. For example, when the production facility is the component mounter 3, the operator performs component replenishment and setup work, and the proper operation state of the component mounter 3 is maintained. Corresponding to each production facility constituting the production line, or in the case where a plurality of production lines are constructed, the responsibility of a plurality of operators is appropriately assigned to each production line. In addition, the “manager” is a person who manages the production facility and has specialized knowledge and skills capable of performing a complicated return work for handling an error.

  As shown in FIG. 1, the host computer 5 is communicably connected to the production facilities 2 to 4, monitors the operation status of the substrate production line 1, and controls the production facilities 2 to 4. Here, the host computer 5 constitutes an information display system together with the detection units 22, 32, 42 and the display units 23, 33, 43 in the production facilities 2 to 4. In the information display system, the host computer 5 performs control for notifying an operator or an administrator of display information corresponding to an error detected in each of the production facilities 2 to 4. The host computer 5 includes a storage unit 51, a determination unit 52, and a display control unit 53.

  The storage unit 51 of the host computer 5 is configured by a hard disk, a flash memory, or the like, and stores a control program and various information for controlling production facilities. The various types of information stored in the storage unit 51 include procedure information Ip and detailed information Id related to errors occurring in the production facility, operator information Ir related to operators, manager information Im related to managers, and presence / absence information Ix.

  Here, the “procedure information Ip” is information indicating an operation procedure for solving an error that has occurred in each of the production facilities 2 to 4, and is defined in advance for each error that may occur in each of the production facilities 2 to 4. ing. The “detailed information Id” is information indicating in detail the errors that have occurred in each of the production facilities 2 to 4, and is intended for the administrator for each high level error that can occur in each of the production facilities 2 to 4. This information is input in advance. The “operator information Ir” is information in which an operator who operates each of the production facilities 2 to 4 is associated with an error type and level that can be handled by the operator.

  The “manager information Im” is information for urging the operator to call a manager who manages each of the production facilities 2 to 4 and is information for identifying the manager. In this manager information Im, information related to one or a plurality of managers who are assigned to manage any of the production facilities constituting the board production line 1 is input in advance. In the present embodiment, the manager information Im includes image information for identifying the manager as shown in FIG. More specifically, this image information is composed of, for example, an administrator's photo, name, and contact information. Further, the administrator information Im may include a record of error handling, a skill level, a priority order for other managers, and the like.

  The “presence / absence information Ix” is information indicating the presence / absence of a plurality of managers when the production facility is managed by a plurality of managers in a shift system. The presence / absence information Ix may include information indicating that the manager is temporarily absent, such as when the administrator has already received a call. In the present embodiment, it is assumed that the production equipment is operated by a plurality of persons in a shift system, and this presence / absence information Ix includes information indicating the presence / absence of a plurality of operators. The presence / absence information Ix can identify the current manager and operator when an error occurs or when the manager is called.

  When an error is detected in each of the production facilities 2 to 4, the determination unit 52 determines whether the operator can deal with the error. At this time, the determination unit 52 determines based on the type and level of the detected error. Here, the “type” of the error includes a mechanical system related to the state and operation of the production facility, a communication system related to communication with the host computer 5, and the like. Further, the “level” of the error is set based on the urgency for stopping or returning the production facility, the difficulty level of the return work in handling the error, and the like.

  The display control unit 53 performs control to switch information to be displayed on the display unit of the production facility where the error has occurred based on the determination result by the determination unit 52 and various information stored in the storage unit 51. More specifically, the display control unit 53 displays the procedure information Ip on the display unit when the generated error can be handled by the operator. Further, when the error that has occurred cannot be handled by the operator, the display control unit 53 displays the administrator information Im on the display unit.

  Further, when the display switching by the administrator is received, the display control unit 53 causes the display unit to display at least one of the detailed error information Id and the procedure information Ip in place of the administrator information Im. Thereby, the display control unit 53 indicates details of the error or an operation procedure for solving the error to the administrator, and prompts the return work. The display switching by the administrator may be performed by a simple key operation, or may be restricted such as requiring input of a password. Further, the display control unit 53 causes the display unit to display the manager information Im of the current manager based on the presence / absence information Ix when an error cannot be dealt with by the operator for an error occurring in the production facility. . Further, when the manager is temporarily absent, a message to that effect may be displayed.

(Display processing of information display system)
Next, display processing by the information display system will be described with reference to FIGS. Here, it is assumed that an error is detected in the detection unit 32 of the component mounter 3 among the plurality of production facilities 2 to 4 configuring the board production line 1. Then, the detection result by the detection unit 32 is input to the host computer 5 via the control device 31. As a result, the host computer 5 recognizes that an error has occurred in the production facility, and executes a display process as shown in FIG.

  First, the host computer 5 analyzes the input error information and identifies a production facility in which an error has occurred among the plurality of production facilities 2 to 4 constituting the substrate production line 1 (S101). Next, the host computer 5 acquires the error type and level based on the error information (S102). As a method for acquiring the error type and level, for example, a method using a preset database is conceivable. More specifically, a database in which the type, level, and error ID are associated with each error that may occur in each production facility is stored in the storage unit 51. Then, the host computer 5 may query the type and level of the error from the database based on the error ID included in the error information.

  Next, the host computer 5 specifies the operator in charge of the production facility where the error has occurred based on the presence / absence information Ix stored in the storage unit 51. Then, the type and level of error that can be dealt with by the identified operator in charge at the present time are acquired from the operator information Ir stored in the storage unit 51 (S103). Then, the determination unit 52 determines whether or not the operator in charge can handle the error based on the detected error type and level and the acquired operator information Ir (S104).

  If it is determined that an error can be handled by the operator for an error that has occurred in the component mounter 3 (S104: Yes), the display control unit 53 acquires the procedure information Ip corresponding to the error from the storage unit 51. (S111). Then, the display control unit 53 sends the acquired procedure information Ip to the component mounter 3 as display information, and causes the display unit 33 of the component mounter 3 to display the procedure information Ip.

  As a result, the control device 31 of the component mounter 3 displays the procedure information Ip on the display unit 33 (S112), and prompts the operator to return. Further, the control device 31 turns off the green notification lamp Le1 and turns on the yellow notification lamp Le2, and displays the error detection result by the detection unit 32. Thereafter, a return operation for error handling by the operator is performed (S113). At this time, the control device 31 monitors whether or not error handling is properly performed according to the procedure information Ip and whether or not error handling has been completed based on signals from various sensors (S114).

  When the next procedure information Ip is required for error handling or when different error handling is required, the control device 31 determines that the error handling has not been completed (S114: No). Then, the control device 31 sends information such as the current state of the component mounter 3 and the progress of error handling to the host computer 5, and obtains the procedure information Ip corresponding to the error again (S111). In this way, S111 to S113 are repeated, and an error recovery operation is performed along the procedure information Ip by the operator. Thereby, when it is determined that the error handling is completed (S114: Yes), the information display system turns off the yellow notification lamp Le2 and turns on the green notification lamp Le1, and ends the display process. .

  In S104, it is assumed that an error that has occurred in the component mounter 3 is determined not to be handled by the operator (S104: No). Then, the display control unit 53 identifies the currently responsible manager of the component mounter 3 in which the error has occurred based on the presence / absence information Ix, and the manager information corresponding to the responsible manager from the storage unit 51. Im is acquired (S121). Then, the display control unit 53 sends the acquired administrator information Im as display information to the component mounter 3 and causes the display unit 33 of the component mounter 3 to display the administrator information Im.

  However, when the manager is temporarily absent, the display control unit 53 displays that fact on the display unit 33 of the component mounter 3 and once again the manager information becomes the manager information. Im may be displayed on the display unit 33. Further, when a plurality of managers are present, only one manager information Im is displayed based on the record of error handling included in the manager information Im and the priority order for other managers. Alternatively, a plurality of administrator information Im may be displayed in accordance with the priority order. Further, when displaying a plurality of administrator information Im, for example, the administrator information Im may be displayed in different colors depending on the results or skill level of the administrator.

  Through the processing described above, the control device 31 of the component mounting machine 3 displays the administrator information Im on the monitor M of the display unit 33 as shown in FIG. 2 (S122), and prompts the calling operator of the administrator. . Then, the manager in charge is called by the operator who visually recognizes the manager information Im (S123). The control device 31 turns off the green notification lamp Le1 and turns on the red notification lamp Le3, and displays the error detection result by the detection unit 32. Subsequently, when the display control unit 53 receives display switching by the administrator, such as a key operation to the operation device or a password input (S124), the display control unit 53 displays at least one of the detailed error information Id and the procedure information Ip from the storage unit 51. Obtained as information (S125).

  Then, the display control unit 53 causes the display unit 33 to display the acquired display information instead of the administrator information Im (S126). The detailed information Id and the procedure information Ip may be sent from the host computer 5 for the first time after the display is switched by the administrator, or sent to the control device 31 together with the administrator information Im and kept in a non-display state. You may make it do. Thereafter, a return operation for error handling by the administrator is performed (S127).

  As in S114, the control device 31 determines whether or not error handling has been completed (S128). When the return work by the administrator is continued (S128: No), information such as the current state of the component mounter 3 and the progress of error handling is sent to the host computer 5 and the details corresponding to the error again. Information Id or procedure information Ip is acquired (S125). In this way, S125 to S127 are repeated, and the return work based on the detailed information Id or the return work along the procedure information Ip is performed by the administrator. Thereby, when it is determined that the error handling is completed (S128: Yes), the information display system turns off the red notification lamp Le3 and turns on the green notification lamp Le1, and ends the display process. .

  In the present embodiment, it has been described that an error has been detected in the detection unit 32 of the component mounter 3. However, the same display process is executed in practice for errors in other production facilities. At this time, among the errors that can occur in each of the production facilities 2 to 4 constituting the substrate production line 1, a plurality of errors having the same type or level share at least a part of display information corresponding to the plurality of errors. Displayed by expression. In other words, the plurality of errors are obtained by using a common shape, pattern, or color, or a combination thereof for at least one of the detection result by the detection unit 32, the procedure information Ip, and the administrator information Im. , 33 and 43, respectively.

  More specifically, for example, when it is determined that the operator in charge can handle an error based on the level of an error that has occurred in each of the production facilities 2 to 4, about the detection result of this level of error, This is notified by the yellow notification lamp Le2. On the other hand, if it is determined that a return work by the administrator is necessary for handling the error, the detection result of this level of error is notified by the red notification lamp Le3. In addition, a common icon may be used for the procedure information Ip and the administrator information Im displayed on the display units 23, 33, and 43, or a common pattern or color may be added to the background of the display information. .

(Effects of the configuration of the embodiment)
The information display system configured as described above can display appropriate information to the operator based on the type and level of error when an error occurs in the production facility. If the operator can handle the error, the procedure information Ip is displayed, and the operator can appropriately handle the error according to the procedure information Ip. When the error handling by the operator is impossible, the administrator information Im is displayed, and the operator is prompted to call the administrator without performing the return work. At this time, since the procedure information Ip is not displayed on the display unit, it is possible to prevent the operator from performing the return operation by mistake. As described above, when an error occurs in the production facilities 2 to 4, the operator can easily determine whether to perform a return operation or to call an administrator based on the display information of the information display system. Thereby, the measure with respect to the error of the production facilities 2-4 is performed appropriately, and downtime can be shortened as a result.

  Further, the display control unit 53 switches the display to the detailed information Id or the procedure information Ip when the display switching by the administrator is accepted. According to such a configuration, the administrator called by the operator can deal with errors based on the detailed error information Id or the procedure information Ip. As described above, the information display system can appropriately support error handling for an administrator who has knowledge and skills capable of handling an error.

  When the information display system prompts the operator to call the administrator, the display control unit 53 displays the administrator information Im based on the presence / absence information Ix. As a result, it is possible to prevent the operator from being urged to call the absent administrator by mistake. Therefore, the operator can call the manager who is present based on the accurate manager information Im.

  The administrator information Im includes image information (photograph, name, contact information, etc.) that identifies the administrator. According to such a configuration, when an error that cannot be dealt with by the operator occurs, the information display system prompts the operator to call the administrator with the administrator information Im including image information. Thus, the operator can reliably call the administrator based on the image information even when the displayed character information cannot be understood due to reasons such as the language being not used regularly.

  The information display system is configured by the detection units 22, 32, and 42 in the production facilities 2 to 4, the display units 23, 33, and 43, and the host computer 5 that is communicably connected to the production facilities 2 to 4. It was supposed to be. Thereby, the information display system can determine in the host computer 5 whether or not an error can be dealt with by the host computer 5 when an error occurs in any of the production facilities 2 to 4 constituting the substrate production line 1. As described above, the host computer 5 manages the procedure information Ip or the manager information Im in correspondence with the error in each of the production facilities 2 to 4 so that the manageability of various information can be improved. Therefore, it is particularly useful to apply the information display system to the board production line 1 controlled by the host computer 5.

  Furthermore, among the errors that can occur in each of the production facilities 2 to 4, a plurality of errors having the same type or level are displayed with a common expression at least a part of the display information corresponding to the plurality of errors. . Thus, the operator can generally grasp the type or level of the error even if the error has occurred in the production facility that is not in charge, based on the displayed information. In addition, the information display system can more clearly display to the operator whether a return operation is performed or an administrator is called when an error occurs. As a result, the operator can easily determine whether to perform a return operation or call an administrator. Therefore, with such a configuration, it is possible to reduce the learning load on the operator and appropriately support error handling.

<Modification of Embodiment>
In the embodiment, the information display system has been described by exemplifying a configuration applied to the substrate production line 1 that produces substrates. On the other hand, the information display system may be configured to be applied to a single production facility or may be configured to be applied to a plurality of production lines. In addition, when the information display system is applied to one production facility, the display control unit classifies errors that may occur in the production facility according to type or level, and handles a plurality of errors belonging to each category. You may make it display at least one part of display information by a common expression. Even in such a configuration, the same effects as in the embodiment can be obtained.
