A work plan creation unit 57 and a display unit 58 are provided. The function of each part constituting the maintenance work support device 5 will be sequentially described together with the contents of various information stored in the storage part 30.

  First, information / data stored in the storage unit 30 will be described. The storage unit 30 stores maintenance related information 31 and maintenance plan data 42. The maintenance related information 31 is information related to one or more maintenance operations executed for each maintenance target. The maintenance related information 31 includes equipment position information 32, maintenance objects 33, maintenance work contents 34, priority table information 35, production performance information 40, and execution history information 41 described below.

  The facility position information 32 and the maintenance target 33 will be described with reference to FIG. As shown in FIG. 4, the maintenance object 33 includes “line NO” 33 a, “unit ID” 33 b, “facility ID” 33 c, “maintenance location” 33 d, and “work type” 33 e. The “line NO” 33a is a number for identifying the component mounting line 4 shown in FIG. 1. By specifying the “line NO” 33a, the component mounting line 4 to be maintained in the component mounting system 1 is specified. The The “unit ID” 33b is an item that comprehensively specifies a range to be subjected to maintenance work. Here, in the configuration shown in FIG. 2, as a comprehensive range when the mounting head 19 is a work target, a comprehensive range in units of mechanism units such as “nozzle head” 1 and “nozzle head” 2, “apparatus” M5, etc. As described above, a comprehensive range set as appropriate, such as a comprehensive range in units of individual devices, is used.

  The “equipment ID” 33c is an identification code for specifying the maintenance target in units of equipment, and is appropriately set in relation to the “unit ID” 33b. Here, in "nozzle head" 1 and "nozzle head" 2 as "unit ID" 33b, these are arranged on the back side (1R) shown in FIG. 2, and "M5" It shows that the entire component mounting apparatus M5 is included in the maintenance work. The “line NO” 33 a, “unit ID” 33 b, and “facility ID” 33 c constitute facility location information 32 that identifies the facility that is the subject of maintenance work in the component mounting system 1.

  The “maintenance location” 33d indicates a location that is specifically a maintenance work execution target. The “work type” 33e indicates a work that is specifically executed for the “maintenance part” 33d. Details of the “maintenance portion” 33d are shown in the maintenance work content 34. Note that the method of dividing the “unit ID” 33b and the “equipment ID” 33c is convenient, and may be appropriately selected according to the management convenience of the maintenance work.

  FIG. 5 shows the maintenance work content 34. Here, "work type" 34b, "work time" 34c, and "work content" 34d are defined for each "maintenance point" 34a. The “maintenance part” 34 a corresponds to the “maintenance part” 33 d of the maintenance object 33. The “work type” 34b indicates the type of maintenance work to be performed for each item shown in the “maintenance part” 34a, for example, the work type such as cleaning, refueling, inspection,. The “working time” 34c indicates a standard time required for executing the work item in units of minutes. The “work content” 34d indicates the detailed execution content of the work item. By contrasting the maintenance object 33 with the maintenance work content 34, it is possible to grasp the work type of the maintenance work, the detailed work execution content, and the time-converted work load.

  Next, the priority table information 35 will be described with reference to FIG. In FIG. 6, “maintenance part” 35 a and “work type” 35 b correspond to “maintenance part” 33 d and “work type” 33 e in the maintenance object 33. Here, with respect to the apparatus main body 38, “nozzle holders” 38a to 38c, “nozzles” 38d to 38f, “nozzle changers” 38g, “conveyors” 38h and 38i, and “power supply unit” 38j are illustrated as examples. A “tape transport path” 39 a is illustrated as an example.

  A recommended maintenance deadline 36 is defined for each maintenance target item defined by the “maintenance location” 35a and the “work type” 35b. The recommended maintenance deadline 36 indicates a deadline for performing maintenance work on the maintenance target item. Specifically, the time limit from the start of use of the maintenance target item to the date and time when the maintenance work should be performed (hereinafter referred to as the use limit time) or the time limit from the start of use of the maintenance target item to the number of times the maintenance work should be performed The time limit is defined by (hereinafter referred to as the use limit number of times). For example, with respect to the item shown in the “nozzle holder” 38a, the maintenance work for the item is performed within 140H from the time when the previous maintenance work was performed, that is, until 140 hours have passed when converted to the usage time in the actual operation state. Is shown to be executed. Note that the usage time (or number of uses) of the maintenance target here refers to the usage time (or the number of times of use) since the start of use from the unused state up to now and the start of use after the previous maintenance work was performed. It includes the usage time (or usage count) from.

  The maintenance priority 37 defines a priority in which the priority for performing maintenance work is classified based on the recommended maintenance deadline 36. The priority order is obtained by dividing the range up to each recommended maintenance deadline 36 into an arbitrary range set in advance. Here, an example is shown in which the priorities are divided into three stages of A, B, and C. For example, for the items shown in the “nozzle holder” 38a, the maintenance priority 37 is defined as AB and C from the highest priority for performing the maintenance work. Further, the “maintenance priority A” 37a is classified into those whose usage time corresponds to 140H to 100H. The “maintenance priority B” 37b is classified into those whose usage time corresponds to 100H to 40H. The “maintenance priority C” 37c is classified into those whose usage time is 40H or less. As shown in FIG. 6, the maintenance priority 37 is determined based on the relationship between the recommended maintenance deadline 36 and the usage time or number of times of maintenance for other items as well.

  That is, the priority table information 35 defines the maintenance priority 37 for classifying the priority order for performing the maintenance work based on the relationship between the recommended maintenance deadline 36 and the usage time or the number of times the maintenance target is used. As the recommended maintenance deadline 36 used here, either a usage time indicating the passage of operating time or a usage count indicating the number of operations in a work operation such as a component mounting operation is appropriately selected and adopted.

  The production performance information 40 indicates the production performance of the component mounting work executed by the component mounting system 1. In the present embodiment, the use of each item indicated in the maintenance target 33 based on the production performance information 40 is used. The time / use count 40a can be acquired. In the present embodiment, the maintenance work support device 5 includes a production information acquisition unit 51, and the production information acquisition unit 51 acquires production information from the management device 3 of the component mounting system 1 via the communication unit 50. .

  These pieces of production information include production result information 40 executed by the component mounting system 1 and information related to a production plan indicating a production operation scheduled to be executed by the component mounting system 1. The execution history information 41 is information indicating a history of maintenance work executed for each maintenance target. The execution history information 41 is acquired by the production information acquisition unit 51 from the management apparatus 3 of the component mounting system 1 in the same manner as the production record information 40, and is used for calculating the maintenance priority 37 described below.

  Based on the execution history information 41 and the priority table information 35 included in the maintenance-related information 31 described above, the priority calculation unit 56 performs the date and time in the operation process of the component mounting system 1 for each maintenance work indicated in the maintenance target 33. Processing for calculating the maintenance priority 37 that changes with the passage of time is performed. In the calculation of the maintenance priority 37, the use time or the number of times of use from the previous maintenance execution time is obtained based on the execution history information 41, and the obtained use time or the number of times of use is referred to the priority table information 35. Then, it is calculated whether the maintenance priority 37 at that time corresponds to “maintenance priority A” 37a, “maintenance priority B” 37b, or “maintenance priority C” 37c.

  In the calculation of the maintenance priority 37, the planned usage time or the planned usage count of each maintenance target is predicted from the production plan acquired by the production information acquisition unit 51, and the planned usage time or the planned usage count of the maintenance target is prioritized. Based on the degree table information 35, a maintenance priority 37 at a date earlier than the information acquisition date may be calculated.

  Based on the maintenance priority 37 calculated by the priority calculation unit 56, the maintenance work plan creation unit 57 performs a process of creating a work plan for maintenance work performed on at least one of the maintenance targets. The created maintenance work plan is displayed by the display unit 58, and the worker who performs the maintenance work executes the work according to the displayed work plan. When creating a maintenance work plan, the maintenance execution date and time is input via the input unit 52 and set by the setting unit 53. The maintenance work plan creation unit 57 creates a maintenance work plan so that the maintenance work is performed by the set maintenance execution date and time. The fact that the maintenance work indicated in the created work plan is to be performed is displayed on the display unit 58 together with the production plan.

  Here, the maintenance plan data created by the maintenance work plan creation unit 57 will be described. The storage unit 30 stores maintenance plan data 42, and the maintenance plan data 42 includes maintenance condition data 43, maintenance priority schedule data 44, and a maintenance work plan table 45. As shown in FIG. 7, the schedule data 44 of the maintenance priority is “according to the passage of time and date of the maintenance priority” for each of the individual maintenance work target items 46a to 46g defined by the maintenance target 33 (see FIG. 4). Transition "44a, that is, a change in the maintenance priority 37 calculated by the priority calculation unit 56 for the item.

  Here, the results of predicting the maintenance priority 37 for each of the dates a1, a2, a3... A6, a7 set for the plan reference are “maintenance priority A” 37a to “maintenance priority C” 37c. Are indicated by A, B, and C. That is, immediately after the maintenance is performed, the maintenance priority 37 is “maintenance priority C” 37c, and the maintenance priority 37 is set to “maintenance priority” by accumulating the usage time or the number of times of use after the device operating days have elapsed. Degree B "37b and" maintenance priority A "37a in order. Based on the schedule data 44 of the maintenance priority created in this way, it is possible to grasp the change in the maintenance priority 37 for each individual maintenance work item, and create a medium / long-term maintenance work plan. The priority order can be reasonably determined.

  Here, the update processing flow of the maintenance priority 37 executed when the maintenance priority schedule data 44 is created will be described with reference to FIGS. 10 and 11. These processes are executed by the function of the priority calculation unit 56. First, referring to FIG. 10, a method for setting the maintenance priority 37 based on the premise that the conventional apparatus operating state is maintained as it is without referring to the production plan will be described. First, the number of times or the usage time of the maintenance target that is the target of the update process of the maintenance priority 37 is acquired (ST1). That is, the usage time / use count 40 a included in the production record information 40 stored as the maintenance related information 31 in the storage unit 30 is read. Next, priority table information 35 corresponding to the acquired maintenance target is acquired (ST2). That is, the priority table information 35 stored in the storage unit 30 as the maintenance related information 31 is read out.

  Then, based on the acquired number of times or time of use and the acquired priority table information 35, the maintenance priority 37 on the information acquisition date is calculated (ST3). The calculated maintenance priority 37 is set to the maintenance priority 37 of the information acquisition date (ST4). Next, the maintenance priority 37 on the date before the information acquisition date is predicted from the acquired use count or use time and the acquired priority table information 35 (ST5). Here, the number of times of use or time of use is estimated and predicted based on the actual performance of the apparatus up to that point, and the date prior to the information acquisition date (for example, maintenance priority schedule data shown in FIG. 7) based on the prediction result. 44, the maintenance priority 37 on the dates a1 to a7) at 44 is predicted. The predicted maintenance priority 37 is set as the maintenance priority 37 of a date earlier than the information acquisition date (ST6).

  Here, the actual performance of the apparatus up to that point in time is, for example, the number of times that the maintenance target equipment is used, the time of use, or the average based on the number of times of use or time of use during a certain period such as one day or one week. It is a value. Also, the setting of the maintenance priority 37 means updating when the maintenance priority 37 to be maintained has been calculated in the past. Further, the maintenance priority 37 on the date before the information acquisition date may be calculated in a predetermined period such as one week or one month, or may be calculated in a period that can be calculated within a range that does not exceed the corresponding recommended maintenance deadline 36. good. Then, by setting the target date and time for the calculated maintenance priority 37 and the predicted maintenance priority 37, schedule data 44 for the maintenance priority shown in FIG. 7 is created.

  Next, with reference to FIG. 11, a method for setting the maintenance priority 37 based on the apparatus operating state scheduled on the production plan with reference to the production plan acquired by the production information acquisition unit 51 will be described. Here, the flow from ST11 to ST14 is the same as the flow from ST1 to ST4 described above, and a description thereof is omitted. Next, the production information acquisition unit 51 acquires a production plan in the component mounting system 1 (ST15). Next, based on the acquired production plan, the planned number of times or planned usage time for maintenance is predicted (ST16). In addition, the forecast of the planned use frequency or the planned use time of the maintenance target may be predicted including at least the facility information used from the acquired production plan and the number of mounted boards to be produced. The estimated usage time may be predicted.

  Next, based on the acquired information, the predicted scheduled number of times or scheduled usage time, and the acquired priority table information 35, the maintenance priority 37 on the date before the information acquisition date is predicted (ST17). Based on the predicted maintenance priority 37, the maintenance priority 37 on the date before the information acquisition date is set (ST18).

  Then, by setting the target date and time for the calculated maintenance priority 37 and the predicted maintenance priority 37, the schedule data 44 of the maintenance priority shown in FIG. 7 is created. As described above, in the calculation of the maintenance priority 37, the maintenance priority 37 to be maintained can be predicted with higher accuracy by referring to the production plan, and the scheduling accuracy can be improved. Yes.

  Next, FIG. 8 and FIG. 12 will be described with respect to the process of creating the maintenance work plan table 45 shown in FIG. 9 based on the maintenance priority schedule data 44 and the maintenance condition data 43 defined in advance. The description will be given with reference. The maintenance condition data 43 shown in FIG. 8 defines allowable conditions for performing maintenance work in the component mounting system 1. The maintenance condition data 43 may be set in advance by an administrator who manages production equipment including a component mounting system, or from a system including worker information such as ERP and time information that allows the worker to perform maintenance work. It is created by acquiring the time during which maintenance work for the worker and the worker can be performed via the management device 3. In the following description, a series of flows for creating the maintenance work plan by acquiring the worker information and the time during which the maintenance work of the worker can be performed from the management apparatus 3 will be described.

  That is, in the pattern 1 shown in FIG. 8A, workers 43a who can work in the component mounting system 1 (here, three persons, XX, XX and XX) and these workers are for maintenance work. A “working time” 43b that can be divided into two is defined in advance. Here, all of the workers XX, XX, and XX can spend 60 minutes for maintenance work. Further, in pattern 2 shown in FIG. 8B, component mounting lines L1 and L2 are defined as work target equipment 43c to which each worker shown to the worker 43a can be assigned. Here, workers XX and XX can be assigned the component mounting line L1, and workers XX can be assigned the component mounting line L2.

  FIG. 12 illustrates a maintenance work plan creation flow based on the maintenance priorities summarized in the form of schedules in the maintenance priority schedule data 44 on the assumption of the maintenance condition data 43 described above. First, the maintenance condition data 43 is acquired and the maintenance execution date and time for executing the maintenance work is set by the setting unit 53 (ST21). In other words, the setting unit 53 sets the maintenance execution date and time when the maintenance work is scheduled to be performed.

  Next, the maintenance target whose maintenance priority 37 is equal to or higher than the maintenance priority B is extracted from the maintenance priority schedule data 44 by the extraction unit 54 by the set maintenance execution date and time (ST22). In other words, the extraction unit 54 selects a maintenance target for which the maintenance priority 37 at the set maintenance execution date / time is determined to be higher than a predetermined category (maintenance priority B in this case) where it is determined that maintenance is desirable. The maintenance priority schedule data 44 is extracted.

  Next, among the extracted maintenance targets, those with a short recommended maintenance deadline 36 are grouped based on a predetermined maintenance condition (ST23). This grouping process is performed by the maintenance work plan creation unit 57. In other words, the maintenance work plan creation unit 57 works so that the maintenance recommended deadline 36 corresponding to the extracted maintenance target is short, that is, the number of times of use or the time of use is close to the use limit time or the use limit number of times. A work plan is created.

  Here, the work time is first taken into consideration as the maintenance condition. As shown in FIG. 8, when one worker performs the maintenance work, the total work time required does not exceed 60 min. This is a condition for grouping. When there is a maintenance target that exceeds the work time of the worker, the worker is made to judge whether the maintenance target is carried over to the next maintenance work based on the maintenance priority 37 or the maintenance condition needs to be reset. Therefore, that effect is displayed on the display unit 58. Accordingly, the worker can easily determine whether to add resources (maintenance worker and maintenance time) necessary for the maintenance work in order to give priority to production or maintenance.

  Next, among the extracted maintenance targets, it is determined whether there is a maintenance target that reaches the recommended maintenance deadline 36 before the set maintenance execution date and time. (ST24). That is, the comparison unit 55 compares the set maintenance date and time with the date and time when the extracted recommended maintenance deadline for maintenance is reached. Then, it is determined whether or not there is a maintenance target whose maintenance recommended deadline is reached by the set maintenance execution date and time (ST25).

  Here, when there is a maintenance target that reaches the recommended maintenance deadline by the set maintenance execution date and time, the display unit 58 displays that there is a maintenance target that reaches the recommended maintenance deadline by the maintenance execution date and time (ST26). After being displayed on the display unit 58, the maintenance execution date and time of the corresponding group is set to a date and time before the date and time when the recommended maintenance deadline is reached (for example, the day before the recommended maintenance deadline is reached) (ST27). That is, the maintenance execution date and time set in (ST21) is advanced, and the maintenance execution date and time is reset so that the maintenance execution date and time when the maintenance work is actually performed is before the recommended maintenance date and time. When the maintenance execution date and time is set, the maintenance work plan flow ends.

  That is, as a result of the comparison by the comparison unit 55, the maintenance work plan creation unit 57 performs maintenance in the work plan when there is a maintenance work plan including a maintenance target that reaches the recommended maintenance deadline by the set maintenance execution date and time. Create a maintenance work plan at the date and time of implementation. Thereby, the maintenance work plan table 45 shown in FIG. 9 is created. In the example shown in FIG. 9, six items out of the seven items of the target items 46a to 46g listed in the maintenance priority schedule data 44 shown in FIG. 7 are divided into three groups (groups 45 (1), 45). (2) and 45 (3)) are grouped into work plans for performing maintenance work.

  Here, in the group 45 (1) in which the date a2 indicated in the schedule data 44 of the maintenance priority is the maintenance execution date and time, the maintenance work is executed with the target items 46a and 46f in FIG. At this time, the total (necessary time) of the “work time” 45a for each item given from the maintenance work content 34 shown in FIG. 5 is the “work time” 43b given in the maintenance condition data 43 shown in FIG. Grouping is performed so as not to exceed (time), and the feasibility at the production site is guaranteed.

  Further, in the groups 45 (2) and 45 (3) in which the date a3 shown in the maintenance priority schedule data 44 is the maintenance execution date and time, the target items 46g, 46b, 46c, and the target item 46e in FIG. As a maintenance work. Similarly, the maintenance work time 45b indicating the total (necessary time) of the “work time” 45a for each item given from the maintenance work content 34 shown in FIG. 5 is stored in the maintenance condition data 43 shown in FIG. The grouping is performed so as not to exceed the given “working time” 43b (allowable time).

  In this way, by grouping a plurality of maintenance targets based on the maintenance conditions defined in advance, it is possible to reduce the number of times the apparatus operation is stopped for maintenance work as much as possible. As a result, the decrease in productivity due to the stoppage of the apparatus for maintenance work, which occurred frequently whenever the equipment and units constituting the component mounting system 1 individually reach the maintenance time in the prior art, is minimized. be able to. In the above example, the maintenance condition data 43 is obtained from the system including the worker information and the time during which the worker can perform the maintenance work, and the maintenance work plan is created. A maintenance work plan may be created by inputting a section. That is, the operator makes a judgment based on the production plan, and creates a maintenance work plan so that the maintenance work can be performed in a time zone when the component mounting line is not operating.

  Next, a series of flows in which the operator inputs maintenance condition data 43 and creates a maintenance work plan will be described with reference to FIGS. First, FIG. 13A shows a state in which the plan display frame 60 and the operation buttons 64 are displayed on the display screen 58 a of the display unit 58. The plan display frame 60 indicates the type of work to be executed on a plurality of target component mounting lines and the execution timetable. That is, the plan display frame 60 includes a date column 61 indicating an execution date, and a line segment column 62 indicating a component mounting line segment (here, “L1” 62a, “L2” 62b, “L2”, “L2” 62b, “ L3 "62c) is displayed. Further, the date column 61 is divided for each time zone by a time zone display column 63 so that work can be displayed and input for each displayed time zone.

  As the operation buttons 64, “plan input” 64a, “import” 64b, “export” 64c, and “registration” 64d are provided, and these buttons are operated by operating the pointer (arrow a) displayed on the screen. By operating, operation input corresponding to each button can be performed. The “plan input” 64a is a button for inputting a maintenance work plan. “Import” 64b is a button for causing the maintenance work support apparatus to import information such as a maintenance work plan created in advance, work support systems other than the component mounting system, or ERP. Information on work support systems other than production plans and component mounting systems can be acquired by “import” 64b, and the information can be used to create maintenance work plans.

  “Export” 64c is a button for exporting information such as the created maintenance work plan to another system such as another maintenance work support apparatus or ERP. Information such as the maintenance work plan created by the “export” 64c can be acquired by the other maintenance work support device 5 and the management device 3 and used to create a work plan for the entire production floor. “Register” 64d is a button for registering the created maintenance work plan table.

  Here, an example is shown in which the pointer (arrow a) is operated in accordance with the “plan input” 64a as the first operation. By this operation, the screen shown in FIG. 13B is displayed on the display screen 58a. On this screen, a setting operation column 65 provided with setting columns for setting the “start time” 65a, “end time” 65b of the work to be executed, and “content” 65c of the work is displayed. In this screen, “L1” 62a indicating the target line L1 in the line classification column 62 and a target time zone 63a intended to perform the work (here, 19: 0 to 20:00) are provided in the setting operation column 65. By operating the selection display operation button 65d with the pointer (arrow b), the screen shown in FIG. 14A is displayed on the display screen 58a.

  In this screen, 19:00 as “start time” 65a and 20:00 as “end time” 65b are input and displayed in correspondence with the operation content, and an option field indicating the selection content in “content” 65c. 66 is displayed. Here, “preparation” 66a, “production” 66b, and “maintenance” 66c are set in the option column 66. By operating the “maintenance” 66c with the pointer (arrow c), FIG. Is displayed on the display screen 58a. As a result, “maintenance” 65g is displayed in “content” 65c in the “setting operation field” 65.

  The worker in charge confirms this screen display and operates the “confirm button” 67 with the pointer (arrow d), thereby confirming the screen display of the work plan execution. That is, the maintenance execution date and time and the allowable time for the work time 70 are set. The worker at the input maintenance execution date is set by obtaining the worker information from the system including the worker information and the time information in which the worker can perform the maintenance work.

  Thereby, the above-described maintenance work plan creation process flow (flow from ST22) is executed. When a maintenance plan is created after execution of the maintenance work plan creation process flow, a maintenance plan work table 68 shown in FIG. 15 is displayed on the display screen 58a. In the maintenance plan work table 68, a “worker name” 69 that performs work together with the maintenance target 33 shown in FIG. 4 and a “work time” 70 that indicates the time required for the work indicate “target” that indicates the target items of the maintenance target 33. Displayed for each “item” 71. Then, a “maintenance work time” 72 that is the sum of the “work time” 70 is displayed for confirmation. Note that a priority update process flow may be performed before the maintenance work plan creation process flow ST22. Since the latest maintenance priority 37 can be extracted by performing the priority update process flow before the maintenance work plan creation process flow ST22, the change in the maintenance priority 37 for each individual maintenance work item can be detected. It is possible to grasp and create a medium- to long-term maintenance work plan.

  At the same time, “maintenance condition change” 73 and “worker confirmation” 74 are set on the display screen 58a. By operating these with the pointer (arrow e), the maintenance condition change operation and work are performed. The person in charge can be confirmed. Then, by operating “Return” 75 and “Confirm” 76, an operation for returning the setting to the original value and an operation for confirming the setting are performed.

  That is, in the maintenance work support system and the production activity support system configured as described above, the work plan created by the maintenance work plan creation unit 57 at the maintenance execution date and time set by the setting unit 53 (the maintenance work plan table 45 shown in FIG. 9). The fact that the maintenance work shown in (2) is to be performed is displayed on the display unit 58 together with the production plan of the component mounting system 1. As a result, maintenance that is indispensable for maintaining production efficiency is achieved by effectively using the gap time during which maintenance work can be performed, such as idle time that occurs in the process of performing various operations such as production and preparation in the component mounting system 1. Work can be performed efficiently.
