Retry number changing means is provided for changing the retry number setting value in a batch without stopping production during production for all the component mounting machines on at least one component mounting line handled by the operator.

Description

  The present invention relates to a production management system for a component mounting line that manages production of at least one component mounting line including a plurality of component mounting machines.

  In general, a component mounting line for mounting components on a circuit board consists of multiple component mounters and devices for each process, such as solder printers, inspection machines, and reflow devices, arranged along the circuit board transport path. Has been. During production, when an operator who manages a component mounting line stands by in the work area around the component mounting line and any trouble or material replenishment request occurs in any device on the component mounting line, A person goes directly to the apparatus and performs operations such as troubleshooting and replenishment of members.

  Further, as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2008-98355), each component mounting machine in the component mounting line succeeds in component suction when a component suction error (component suction failure) occurs. The retry operation (re-part suction operation) is repeated within the range of the preset retry count setting value until the operation is repeated. In addition, when the suction posture of the part sucked by the suction nozzle is abnormal (for example, standing suction, oblique suction, etc.), the part is discarded in a predetermined disposal place and the retry operation is set to a preset retry count setting value. If it is repeated within the range or the part is an expensive part, the part is placed on a collection conveyor and collected for re-use during the retry operation. The retry operation is also called a recovery operation.

JP 2008-98355 A

  If any trouble or request for replenishment of parts occurs in a device other than a component mounting machine (for example, a solder printing machine, inspection machine, etc.) during production, the operator goes directly to the equipment and performs work such as troubleshooting and replenishment of parts. However, if a component suction error (component suction error, component suction posture abnormality, etc.) occurs in any of the component mounting machines during this work, the component mounting machine repeats the retry operation. As a result, when the number of retries reaches a preset retry number setting value, the operation of the component mounter stops and production stops. In general, the number of workers in charge of production management of a component mounting line is one or less for one component mounting line, so the worker goes directly to a device other than the component mounting machine. During the process, even if the retry count of any of the component mounters reaches the preset retry count setting value and the operation of the component mounter stops, the operator goes directly to the component mounter and works. Can't do it. In such a situation, the production stop time becomes longer and the operation rate of the component mounting line decreases.

  As a countermeasure, it is conceivable to increase the retry count setting value in advance.However, if the retry count increases, if the retry operation is repeated due to an abnormality in the component adsorption posture, there are parts for the preset retry count. Since the number of parts that are discarded and is wasted increases, it is not a good idea to increase the retry count setting value in advance.

  Therefore, the problem to be solved by the present invention is to reduce the frequency at which the number of retries of any of the component mounting machines on the component mounting line reaches the retry number setting value and stop the operation of the component mounting machine, It is to provide a production management system for a component mounting line that can improve the operation rate of the line and reduce the number of parts discarded (recovered number) due to a retry operation during normal production.

  In order to solve the above-described problems, the present invention provides a component management system for managing a production of at least one component mounting line including a plurality of component mounting machines. Is equipped with a function that repeats retry operation within the range of the number of retry times until the component suction is successful when each component suction error occurs, and at least one component mounting line The component mounting machine includes a retry number changing unit that collectively changes the retry number setting value without stopping production during production.

  In this configuration, the number of retries can be changed in a batch without stopping production during production for all the component mounting machines on at least one component mounting line handled by the operator. During a simple operation or no operation, the retry count setting value is temporarily increased more than usual, and the retry count of one of the component mounting machines on the component mounting line reaches the retry count setting value. It is possible to reduce the frequency at which the operation stops, and to improve the operation rate of the component mounting line. Moreover, the number of parts discarded due to the retry operation during normal production can be returned to the normal retry number setting value without a simple operation or operation during the production. Can be reduced.

  In this case, the retry frequency changing means may be provided in each component mounting machine of the component mounting line so that the operator can change the retry frequency setting value. For example, each component mounter on the component mounting line may be provided with an operation unit for changing the retry count setting value as a retry count changing means.

  Alternatively, the retry frequency changing means may be configured to display a screen for the operator to change the retry frequency setting value on the monitoring device of each component mounting machine of the component mounting line. In this way, it is not necessary to provide a new operation unit for changing the setting value of the number of retries on each component mounter, and the cost can be reduced correspondingly, and the operator can monitor any component mounter. By operating the apparatus, it is possible to collectively change the retry count setting value for all the component mounting machines on at least one component mounting line that the worker is in charge of.

  Alternatively, the retry frequency changing means may be configured by mounting a function for an operator to change the retry frequency setting value in a production management computer that manages the production of the component mounting line. In this way, when the operator operates the production management computer, it is possible to collectively change the retry count setting value for all the component mounting machines on at least one component mounting line.

  Alternatively, the retry count changing means may be configured by mounting a function for an operator to change the retry count setting value in an information device connected to the component mounting line network by a wireless LAN or a wired LAN. Here, the information device may be any one of portable terminals such as a personal computer, a tablet computer, and a smartphone.

  In addition, if it is determined that a component sucked by the suction nozzle of each component mounting machine is not mountable (component suction error), whether or not the component is recovered and reused depending on whether the component is a predetermined recovery component When the present invention is applied to a component mounting line configured to select whether to discard, the retry count changing means determines whether the retry count depends on whether or not a component determined to be unmountable is a predetermined recovered component. The set value may be automatically changed. In general, since parts that are collected and reused are expensive parts, it is better to reduce the number of retries from the viewpoint of suppressing cost increase. On the other hand, parts that are discarded without being collected are relatively inexpensive parts. Therefore, even if the number of retries is increased, the cost increase can be almost ignored, and the production cost can be reduced by increasing the number of retries and reducing the frequency at which the operation of the component mounting machine is stopped. Therefore, when the component that is determined to be unmountable is a predetermined recovered component, the retry count setting value is set to the smaller setting value (normal setting value) until the operation of the component mounting machine stops. If the number of retries should be reduced, on the other hand, if the part that is determined to be unmountable is not a predetermined collected part but a part to be discarded, change the retry number setting value to the larger setting value and mount the part. It suffices to increase the number of retries until the machine stops operating.

  Further, the present invention includes worker detection means for detecting the presence or absence of a worker in a work area around the component mounting line, and the retry number changing means depends on the presence or absence of the worker detected by the worker detection means. Then, the retry count setting value may be automatically changed. Here, what is necessary is just to comprise an operator detection means using a camera, a human sensitive sensor, GPS, etc., for example. For example, when it is detected that the worker has left the work area around the component mounting line, the retry count setting value is changed to a setting value that is larger than normal until the operation of the component mounting machine stops If the number of retries is increased, the frequency at which the operation of the component mounter stops during production can be reduced to improve the operation rate of the component mounting line. In addition, if it is detected that the worker has returned to the work area around the component mounting line, the retry count setting value can be returned by returning the retry count setting value to the normal lower setting value. Forgetting can be prevented.

  In this case, the worker detection means may be configured using, for example, a camera, a human sensor, GPS, or the like, or detects the presence or absence of the worker based on the operator's operation or external input by the work. May be. Here, the external input by the operator's operation or work is, for example, screen operation or key operation of the monitor device, attachment / detachment of a feeder, reading of a barcode, etc. This means that the worker is performing an operation or work in the work area around the area, so that the presence or absence of the worker can be detected based on the external input.

  The present invention further includes an operation status detection unit that detects an operation status of each device on the component mounting line, and the retry count changing unit is configured to determine an operation status of each device on the component mounting line detected by the operation status detection unit. Accordingly, the retry count setting value may be automatically changed. For example, if an error has occurred in a device other than the component mounter, or if it can be determined that the worker is performing some work on the device because the cover is open, etc. Even if some trouble occurs in one of these component mounters, it is difficult for the operator to rush to the component mounter and work immediately. By changing the setting value and increasing the number of retries until the operation of the component mounter is stopped, the operation rate of the component mounter is improved by reducing the frequency at which the operation of the component mounter stops during production. Can be made.

  The present invention further includes a work instruction means for instructing an operator to perform work, and the retry number changing means automatically changes the retry number setting value in accordance with the work content instructed by the work instruction means. Also good. For example, when work on an apparatus other than a component mounter is instructed, the work on the component mounter cannot be performed while the worker is performing the instructed work. If the number of retries is increased until the operation of the component mounter stops, the frequency of the component mounter operation being stopped during production can be reduced. The operating rate can be improved.

  The present invention further includes a work status determination unit that determines whether or not an operator who manages the component mounting line performs work on an apparatus other than the component mounting machine, and the retry count changing unit includes the work status The setting value for the number of retries may be automatically changed in accordance with the presence / absence of work to be performed on an apparatus other than the component mounter determined by the determination unit. For example, while the worker is working on a device other than the component mounter, the work on the component mounter cannot be performed, so the retry count setting value is changed to a setting value that is larger than usual, If the number of retries until the operation of the component mounter stops is increased, the frequency at which the operation of the component mounter stops during production can be reduced, and the operation rate of the component mounting line can be improved.

  In addition, the present invention includes a time measuring unit that measures the duration of the state when the retry number changing unit increases the retry number setting value, and the retry number changing unit includes a time measured by the time measuring unit for a predetermined time. It is also possible to automatically reduce the retry count setting value when the value exceeds. In this way, when the retry count setting value is increased, the retry count setting value can be automatically returned to the smaller setting value after a predetermined time has elapsed, thereby preventing the retry count setting value from being forgotten to be returned. can do.

  Further, according to the present invention, the production program for executing the production of the component mounting line includes a process for determining whether or not the production is production for which the retry number setting value is changed by the retry number changing unit. In the case of production that is included and is not subject to change of the retry count setting value by the retry count changing means, the change prohibiting means for prohibiting the change of the retry count setting value by the retry count changing means Also good. In this way, it is possible to prevent the retry count setting value from being changed accidentally in the case of production that is not subject to change of the retry count setting value.

FIG. 5 is a flowchart (part 2) showing the flow of processing of the retry count setting value changing program.

Hereinafter, an embodiment embodying a mode for carrying out the present invention will be described.
First, the configuration of the component mounting line will be described with reference to FIGS.

  In a factory for producing a component mounting board, at least one component mounting line 10 is installed. On the base table 11 of the component mounting line 10, a plurality of component mounting machines 12 are arranged so as to be replaceable adjacent to each other in the conveyance direction (X direction) of the circuit board 22. Each component mounting machine 12 is used for imaging a component on a main body bed 13 for imaging a component adsorbed by a feeder 14 such as a tape feeder for supplying components, a conveyor 15 for conveying a circuit board 22, and a suction nozzle (not shown). Camera 16, a mounting head 17 that holds one or a plurality of suction nozzles, a mark imaging camera (not shown) that images a reference mark on the circuit board 22, and the like. The mounting head 17 is moved in the XY direction by an XY moving mechanism (not shown) to perform a component suction operation and a component mounting operation.

  On the front surface portion of the upper frame 18 of each component mounting machine 12, a monitor device 19 such as a liquid crystal display or CRT, and an operation unit 20 such as operation keys or a touch panel are provided. When the operation unit 20 is configured by a touch panel, the operation unit 20 may be displayed on the screen of the monitor device 19.

  In addition, as shown in FIG. 2, in the component mounting line 10, in addition to a plurality of component mounting machines 12, devices for each process such as a solder printer 23, an inspection device 24, and a reflow device 25 are provided on the circuit board 22. They are arranged along the transport path 26.

  Furthermore, a human sensor 27 is provided on the front surface of the upper frame 18 of each component mounter 12 as worker detection means for detecting the presence or absence of a worker in the work area around the component mounting line 10. Similarly, on the front side of each process device such as the solder printer 23, the inspection device 24, the reflow device 25, etc., a human sensor 27 as a worker detection means for detecting the presence or absence of a worker in the peripheral work area. Is provided. When the detection area of the human sensor 27 is wide, it is not necessary to provide one human sensor 27 for each of the devices 12 and 23 to 25 of the component mounting line 10. The human sensor 27 may be arranged so that the presence or absence of workers in the work area can be detected.

  The control device 31 that controls the operation of each component mounter 12 is configured mainly by a computer, and conveys the circuit board 22 conveyed from the upstream component mounter 12 to a predetermined position by the conveyor 15 to a clamping mechanism ( (Not shown), the circuit board 22 is clamped and positioned, and the component supplied by the feeder 14 is sucked to the suction nozzle of the mounting head 17, and the mounting head 17 is moved to the imaging position, and the mounting is performed. After picking up the part sucked by the picking nozzle of the head 17 with the part imaging camera 16 and processing the image, it recognizes the presence / absence of the part (presence / absence of part picking error), part picking position shift, part picking posture, etc Mounted on the circuit board 22 on the conveyor 15.

  At that time, the control device 31 of each component mounter 12 detects a component suction error (component suction failure) or a component suction posture abnormality (for example, standing up) based on the processing result of the captured image of the component imaging camera 16 during component imaging. If it is determined whether the component suction is wrong, the retry operation (re-part suction operation) is within the range of the retry count setting value described later until the component suction succeeds. Repeat with. If it is determined that the suction posture of the part sucked by the suction nozzle is abnormal, the part is discarded in a predetermined disposal place and the retry operation is repeated within the range of the retry count setting value described later. In the case of an expensive part, the part is collected on a collection conveyor (not shown) in order to reuse the part during the retry operation. In the following description, component suction mistakes, component suction posture abnormalities, and the like, which are conditions for performing the retry operation, are collectively referred to as “component suction errors”.

  The production of the component mounting line 10 described above is managed by the production management computer 32. Connected to the production management computer 32 are an input device 33 such as a keyboard and a touch panel, a monitor device 34 for displaying production management information, and the like.

In general, the number of workers in charge of production management of the component mounting line 10 is one or less for one component mounting line 10, and one worker manages production of a plurality of component mounting lines 10. There is also a case. Therefore, in this embodiment, the retry number setting value is collectively changed without stopping the production for all the component mounting machines 12 of the at least one component mounting line 10 that the worker is in charge of during the production. The number of times changing means is provided.
Hereinafter, various retry frequency changing means of the present embodiment will be described.

[Retry count changing means (1)]
The retry number changing means (part 1) is provided in each component mounting machine 12 of the component mounting line 10 so that the operator can collectively change the retry number setting values for all the component mounting machines 12. . For example, each component mounter 12 of the component mounting line 10 may be provided with an operation unit for changing the retry count setting value as a retry count changing means.

  Alternatively, as shown in FIG. 3, the monitor 19 of each component mounter 12 in the component mounting line 10 may be configured to display a screen for changing the retry count setting value. In the example of FIG. 3, when the screen of the monitor device 19 is switched to the retry count change screen, a retry count setting button 35 is displayed on the screen. The operator changes the retry count setting value by operating the retry count setting button 35. The retry count setting value may be changed in two steps or three or more steps, or may be changed to an arbitrary number. The information on the changed retry count setting value is transmitted to the control device 31 of each component mounter 12 using the network of the component mounting line 10, and the retry count setting value used by each component mounter 12 is changed in a batch. Is done.

  If a screen for changing the retry count setting value by the operator is displayed on the monitor device 19 of each component mounter 12, a new operation unit for changing the retry count setting value is newly provided on each component mounter 12. There is no need to provide it, and the cost can be reduced correspondingly, and when the operator operates the monitor device 19 of any of the component mounting machines 12, all of the at least one component mounting line 10 that the operator is in charge of. It is possible to collectively change the retry count setting value for the component mounting machine 12.

[Retry count changing means (2)]
The retry number changing means (part 2) is configured by mounting a function for the operator to change the retry number setting value in the production management computer 32 that manages the production of the component mounting line 10. The retry count setting value may be changed in two steps or three or more steps, or may be changed to an arbitrary number. The information on the setting value of the number of retries changed by operating the production management computer 32 is transmitted to the control devices 31 of all the component mounting machines 12 on the component mounting line 10 using the network of the component mounting line 10, and each component mounting is performed. The retry number setting value used in the machine 12 is changed at once.

  In this case, when the operator operates the input device 33 of the production management computer 32, the retry count setting values are collectively set for all the component mounting machines 12 of the at least one component mounting line 10 that the worker is in charge of. And can be changed.

[Retry count change means (part 3)]
The retry number changing means (part 3) includes a function for an operator to change the retry number setting value in an information device (not shown) connected to the network of the component mounting line 10 by a wireless LAN or a wired LAN. It is configured. Here, the information device may be any one of portable terminals such as a personal computer, a tablet computer, and a smartphone. The retry count setting value may be changed in two steps or three or more steps, or may be changed to an arbitrary number. The information on the setting value of the number of retries changed by operating the information device is transmitted to the control devices 31 of all the component mounters 12 of the component mount line 10 using the network of the component mount lines 10, and each component mounter 12. The retry setting value used in is changed at once.

  In this case, when the operator operates the information device, the retry count setting value can be collectively changed for all the component mounting machines 12 of at least one component mounting line 10 that the worker is in charge of. it can.

[Retry count changing means (4)]
The retry number changing means (No. 4) is mounted on the control device 31 of each component mounting machine 12, and in the component imaging process, based on the processing result of the captured image of the component imaging camera 16, a component adsorption error (unmountable) and The retry count setting value is automatically changed depending on whether or not the determined component is a predetermined recovered component. The information on the changed retry count setting value is transmitted to the control device 31 of each component mounter 12 using the network of the component mounting line 10, and the retry count setting value used by each component mounter 12 is changed in a batch. Is done.

  In general, since parts that are collected and reused are expensive parts, it is better to reduce the number of retries from the viewpoint of suppressing cost increase. On the other hand, parts that are discarded without being collected are relatively inexpensive parts. Therefore, even if the number of retries is increased, the cost increase can be almost ignored, and the production cost can be reduced by increasing the number of retries and reducing the frequency at which the operation of the component mounting machine 12 stops. Therefore, the control device 31 of each component mounting machine 12 sets the retry number setting value to the smaller setting value (normal setting value) when the component determined to be component adsorption error (unmountable) is a predetermined recovered component. ) To reduce the number of retries until the operation of the component mounting machine 12 stops, while the component determined to be a component adsorption error (cannot be mounted) is not a predetermined recovered component but a discarded component. Is configured to increase the number of retries until the operation of the component mounting machine 12 is stopped by changing the setting value for the number of retries to the larger setting value.

[Retry count changing means (5)]
A human sensor 27 is provided in each component mounting machine 12 of the component mounting line 10 and other devices 23 to 25 as worker detecting means for detecting the presence or absence of workers in the work area around the component mounting line 10 and retry. The number changing means (No. 5) is mounted on the control device 31 of each component mounting machine 12 of the component mounting line 10 and the control device (not shown) of the other devices 23 to 25, or the production management computer 32, and The retry count setting values of all the component mounting machines 12 in the component mounting line 10 are automatically changed collectively according to the presence or absence of the worker detected by the sensor 27. Here, the worker detection means may be configured using, for example, a camera, GPS, etc., in addition to the human sensor 27. For example, when it is detected that the worker has left the work area around the component mounting line 10, the retry number setting value is changed to a setting value that is larger than usual, and the operation of the component mounting machine is stopped. It is only necessary to set the number of retries until the number of retries is increased, thereby reducing the frequency at which the operation of the component mounting machine 12 stops during production and improving the operating rate. In addition, when it is detected that the worker has returned to the work area around the component mounting line 10, the retry count setting value may be returned to the normal lower setting value. It is possible to prevent forgetting to return the set number of times.

  In this case, the worker detection means is not limited to the human sensor 27, the camera, the GPS, or the like, and may detect the presence or absence of the worker based on the operator's operation or external input by the work. Here, the external input by the operator's operation or work is, for example, the screen operation or key operation of the monitor device 19, the attachment / detachment of the feeder, the reading of the barcode, and the like. This means that an operator is performing an operation or work in the work area around the line 10, and therefore the presence or absence of the worker can be detected based on an external input.

[Retry count change means (6)]
The control device 31 of each component mounting machine 12 of the production management computer 32 or the component mounting line 10 and the control device (not shown) of other devices 23 to 25 operate the respective devices 12 and 23 to 25 of the component mounting line 10. In addition to functioning as an operating status detecting means for detecting the status, it also functions as a retry number changing means (No. 6), and the operating status of each device 12, 23 to 25 of the component mounting line 10 detected by the operating status detecting means. Accordingly, the retry count setting values of all the component mounting machines 12 in the component mounting line 10 are automatically changed collectively. For example, when an error has occurred in the devices 23 to 25 other than the component mounter 12, or when it can be determined that the worker is performing some work on the device because the cover is open, etc. If any trouble occurs in any of the component mounters 12, it is difficult for the operator to rush to the component mounter 12 and work immediately. Change to a setting value that is larger than normal, and increase the number of retries until the operation of the component mounter stops. Thereby, the operation rate of the component mounting line 10 can be improved by reducing the frequency at which the operation of the component mounting machine 12 stops during production.

[Retry count change means (7)]
The control device 31 of each component mounting machine 12 of the production management computer 32 or the component mounting line 10 and the control devices of the other devices 23 to 25 function as work instruction means for instructing the worker to perform work and change the number of retries. It also functions as (No. 7), and automatically changes the retry count setting values of all the component mounting machines 12 of the component mounting line 10 in accordance with the work content instructed by the work instruction means. For example, when work on the devices 23 to 25 other than the component mounter 12 is instructed, the work on the component mounter 12 cannot be performed while the worker is performing the instructed work. The setting value is changed to a setting value that is larger than usual so that the number of retries until the operation of the component mounting machine 12 stops is increased. Thereby, the operation rate of the component mounting line 10 can be improved by reducing the frequency at which the operation of the component mounting machine 12 stops during production.

[Retry count changing means (8)]
In the control device 31 of each component mounting machine 12 of the production management computer 32 or the component mounting line 10 and the control devices of the other devices 23 to 25, the retry count changing means (parts 1 to 7) increases the retry count setting value. Sometimes it functions as a timekeeping means (timer) for measuring the duration of the state, and also functions as a retry number changing means (part 8). When the time measured by the timekeeping means exceeds a predetermined time, the component The retry number setting value of all the component mounting machines 12 on the mounting line 10 is automatically decreased. In this way, when the retry count setting value is increased, the retry count setting value can be automatically returned to the smaller setting value after a predetermined time has elapsed, thereby preventing the retry count setting value from being forgotten to be returned. can do.

  In this case, the “predetermined time” (elapsed time until the retry count setting value is returned to the smaller setting value) measured by the time measuring means may be a preset fixed value, or the operator arbitrarily It may be settable. Further, the measurement time of the time measuring means may be displayed on the screen of the monitor device 19, 34 or the like by a count-up or count-down method. Alternatively, the operator may stop the measurement operation in the middle of the measurement operation of the time measuring means and return the retry number setting value to the smaller setting value (normal setting value). Further, during the measurement operation of the time measuring means (that is, the period during which the retry count setting value is increased), it may be displayed on the screens of the monitor devices 19 and 34 so that it can be easily understood that the retry count setting value has increased. good.

[Retry count changing means (9)]
The production program for executing the production of the component mounting line 10 includes a process for determining whether or not the production is production for which the retry number setting value is changed by the retry number changing means (parts 1 to 8). The control device 31 of each component mounter 12 of the production management computer 32 or the component mounting line 10 and the control devices of the other devices 23 to 25 are set by the retry number changing means (parts 1 to 8). When the production is not subject to change of the value, it functions as a change prohibiting means for prohibiting the change of the retry number setting value by the retry number changing means (parts 1 to 8). In this way, it is possible to prevent the retry count setting value from being changed accidentally in the case of production that is not subject to change of the retry count setting value.

  A function for selecting the retry frequency changing means used by the operator may be added from the 9 examples of the retry frequency changing means (1 to 9) described above, and the retry frequency changing means (1 to 9). Some of 9) may be omitted.

  Hereinafter, an example of the retry count setting value changing procedure will be described using the retry count setting value changing program of FIGS. 4 and 5. In this program, the retry count setting value is changed in two stages. Normally, the retry count setting value is set to the smaller setting value (normal setting value).

  4 and 5 is executed at a predetermined cycle during production by the production management computer 32 or the control device 31 of each component mounting machine 12 of the component mounting line 10 or the control devices of the other devices 23 to 25. Repeatedly executed. When this program is started, first, at step 101, it is determined whether or not the operator has performed an operation of changing the retry count setting value by using the retry count changing means (any one of 1 to 3). As a result, if it is determined that the operator has performed a change operation, the process proceeds to step 102, where it is determined whether or not the change is made to increase the retry count setting value. Proceeding to 103, the retry count setting value is set to a larger setting value than usual, and this program is terminated.

  On the other hand, if it is determined in step 102 that the change is not to increase the retry count setting value, the process proceeds to step 104, where the retry count setting value is set to the smaller setting value (normal setting value). Exit this program.

  If it is determined in step 101 that the operation for changing the retry count setting value has not been performed, the process proceeds to step 105, and any one of the component mounting machines is used by using the retry count changing means (part 4). 12, it is determined whether or not a component suction error (component suction error, component suction posture abnormality, etc.) has occurred. Since the component mounting machine 12 in which the component suction error has occurred performs a retry operation, if it is determined in step 105 that a component suction error has occurred, the process proceeds to step 106, which causes the component suction error. It is determined whether the part is a part that is collected and reused. As a result, if it is determined that the component is to be collected and reused, the process proceeds to step 107, the retry count setting value is set to the smaller setting value (normal setting value), and the present program is terminated.

  On the other hand, if it is determined in step 106 that the part is not a component to be collected and reused, the process proceeds to step 108, the retry count setting value is set to a setting value larger than normal, and the program is terminated.

  If it is determined in step 105 that a component suction error has not occurred, the process proceeds to step 109 in FIG. 5, and each device of the component mounting line 10 is used by using the retry number changing means (part 6). Judgment is made from the operating statuses of 12, 23 to 25, and it is determined whether or not it can be determined that the worker is working on the devices 23 to 25 other than the component mounter 12. As a result, when it can be determined that the worker is working on the devices 23 to 25 other than the component mounting machine 12, the process proceeds to step 110, and the retry count setting value is set to a setting value that is larger than usual. Exit this program.

  On the other hand, if it cannot be determined in step 109 that the worker is working on the devices 23 to 25 other than the component mounter 12, the process proceeds to step 111, and the retry number changing means (part 7) Is used to determine whether or not an operation for the devices 23 to 25 other than the component mounter 12 has been instructed. As a result, if it is determined that an operation for the devices 23 to 25 other than the component mounting machine 12 has been instructed, the process proceeds to step 112, the retry count setting value is set to a setting value that is larger than usual, and this program is terminated. To do.

  On the other hand, if it is determined in step 111 that the work for the devices 23 to 25 other than the component mounter 12 is not instructed, the process proceeds to step 113, where the component is changed using the retry number changing means (part 5). It is determined whether or not there is a worker in the work area around the mounting line 10. As a result, if it is determined that there is a worker in the work area around the component mounting line 10, the process proceeds to step 114 where the retry count setting value is set to the smaller setting value (normal setting value) and this program Exit.

  On the other hand, if it is determined in step 113 that there is no worker in the work area around the component mounting line 10, the process proceeds to step 115, and the retry count setting value is set to a setting value that is larger than usual. To finish this program.

  In the above-described steps 103, 108, 110, 112, and 115, when the retry number setting value is set to a larger setting value than usual, the retry number changing means (No. 8) is used to retry. When the number of times setting value is increased, measurement of the duration of the state is started, and when the measured time exceeds the predetermined time, the retry number setting value is automatically returned to the smaller setting value. Also good.

  Further, as the execution condition of this program, the retry number changing means (No. 9) is used to determine whether or not the current production is the target of changing the retry number setting value, and retrying is performed. When the production is not subject to change of the number of times setting value, the change of the number of times of retry setting may be prohibited (execution of this program is prohibited).

  According to the present embodiment described above, the number of retries is collectively set for all the component mounting machines 12 of at least one component mounting line 10 handled by the operator without stopping the production during the production. Since it can be changed, the number of retries of the component mounting machine 12 on the component mounting line 10 can be retried by temporarily increasing the number of retries than usual with simple operation or no operation during production. It is possible to reduce the frequency at which the operation of the component mounting machine 12 stops when the number setting value is reached, and the operation rate of the component mounting line 10 can be improved. Moreover, the number of parts discarded due to the retry operation during normal production can be returned to the normal retry number setting value without a simple operation or operation during the production. (Recovery number) can be reduced.

  The present invention is not limited to the above-described embodiment. For example, even if the configuration of the component mounting line 10 is changed or the processing procedure of each step of the retry count setting value changing program of FIGS. 4 and 5 is changed. Needless to say, various modifications can be made without departing from the scope of the invention.
