Maintenance work support system for component mounting systems, including

Since the support system of the present invention is a system that can create a maintenance work plan for a component mounting system including a plurality of mounting-related work machines, the maintenance work plan for one component mounter described in the prior art can be prepared. Different from what you create, it is convenient. Generally, a factory that assembles electronic circuits has one part. Since not only the component mounting machines are arranged, but also multiple lines connecting various mounting-related working machines are often arranged, the support system of the present invention is applied to all factories that assemble electronic circuits. Can be used for In addition, in a component mounting system in which a plurality of mounting-related work machines are provided, there are many maintenance work items, and it is difficult to select an appropriate work item from those many items. In view of this, by creating an appropriate maintenance work plan using the support system of the present invention, it is possible to effectively prevent forgetting to perform maintenance, excessive maintenance, and the like. Further, if the support system of the present invention is used, it is possible to perform maintenance work with high efficiency in terms of time or efficiency of maintenance personnel.

In the present invention, the "mounting-related work machine" includes a component mounting machine for mounting circuit components on a circuit board, for example, a solder printing machine for printing cream solder on a circuit board, and an adhesive for applying an adhesive to the circuit board. Dispensing machine (also called “dispenser”), heating furnace that heats the circuit board on which the circuit components are mounted and solders the circuit components (for example, “reflow furnace”), inspection to inspect the mounting results A work machine that performs various operations related to component mounting work, such as a work machine and a board transfer machine that transfers a circuit board between the work machines. The “component mounting system” to which the present invention is applied is a mode in which only one type of these components is included in a plurality, and a configuration in which each of multiple types includes one or more types. Including both. Specifically, for example, a mode in which several mounting-related work machines are configured to include one or more component mounting lines arranged in series, and in extreme cases, all components in one factory An embodiment including a mounting line also applies. The "components" of an implementation-related implement may include any of a variety of different things depending on the type of implementation-related implement. In the case of a component mounter, for example, component elements such as a component supply device such as a feeder, a circuit board holding device, and a mounting device, and further lower-level devices that configure those devices (for example, a mounting head in a mounting device). Etc.), components, members, subordinate devices, subordinate devices that make up the components, components (eg, suction nozzles), members, etc., can be various components having different conceptual sizes. The “components” may be fixedly mounted on the mounting-related working machine. As shown in the figure above, it can be attached to and detached from the main body of the mounting-related work machine, and can be arbitrarily attached to the main body of the mounting-related work machine according to the target of the mounting work such as the type of board, the mounting work form, etc. May be.

In the present invention, the “maintenance target” may be only the above-mentioned mounting-related work machine, or may be only the above-mentioned constituent element. Further, both a mounting-related work machine and its components may be included. If maintenance work is to be performed on components that are fixedly mounted on the mounting-related work equipment or components that are removable and are currently mounted during maintenance work, the maintenance work must be performed. However, it can be handled not as maintenance work for components, but as maintenance work for mounting-related working machines. In other words, in such a case, the mounted component is regarded as a part of the mounting-related work machine, and the “maintenance target” can be set to the mounting-related work machine including the component.

In the present invention, the “maintenance work” is not particularly limited, and the concept includes various works such as inspection, maintenance, maintenance, and the like which are usually considered. Specifically, for example, the work of checking the appearance, arrangement position, operation, etc. of the above-mentioned maintenance object or a part thereof, the lubrication work of the sliding part, the power transmission part, etc. of the maintenance object, the maintenance object or a part thereof, Various tasks include cleaning work, replacement of consumable parts and maintenance-restricted parts that make up the maintenance target, and disposal of the maintenance target and its constituent parts.

In the present invention, the format of the “maintenance work item” included in the “maintenance data” is not particularly limited, as long as it can specify each maintenance work of each maintenance target. For example, various forms such as a work name, a work content type name, and a code representing the work content may be used. The “implementation frequency” may be any frequency on a time scale, the number of operations, the frequency on a work quantity scale such as production volume, or the like. Further, the “implementation frequency” may indicate a cycle or a limit. For example, once for every fixed period of time regardless of whether the maintenance target is running or not, or XX hours have passed in the operation time and operation time of the maintenance maintenance object It is possible to employ various frequencies, such as performing maintenance work at the time of production, performing maintenance work when yy circuit boards are produced, or mounting _ZZ circuit components.

In the present invention, the “plan” to be created is not limited in its purpose of use, form of notification, and the like. For example, it may be any one that indicates a schedule of maintenance work in a broad sense. For example, it may be a guideline for a maintenance work executor, a maintenance work manager, and the like. The contents of the plan can be in various forms depending on the purpose of use. For example, it may be a mode in which only maintenance work items performed at a certain time when maintenance work is performed are included, and the maintenance work items may be arranged in some order, hierarchically, or classified. It may be of the embodiment described. For example, the order in which the tasks are performed involves a priority, a rank, a grade, and the like of the power task. Further, the maintenance work item may be accompanied by different data or associated with different data, and may be in a form including such data.

In the present invention, it is not necessary that the time when a plan is created coincides with the time when a maintenance work based on the plan is performed. For example, a maintenance work plan may be created the day before the maintenance work is performed. If the maintenance work is scheduled at a predetermined time, the maintenance work is scheduled to be scheduled at the time when the maintenance work plan is created. Alternatively, the maintenance work plan may be automatically created automatically.

In the present invention, the form relating to the specific process of preparing the maintenance work plan is not particularly limited. For example, in the support system of the present invention, the maintenance data holding unit stores, as the maintenance data, data including the latest execution time, which is the time of the most recently performed maintenance work, of each of the held maintenance work items. The maintenance work plan creation unit has: (i) a maintenance object selection unit that selects maintenance objects for which maintenance work is scheduled;

(ii) From the maintenance work items for the selected maintenance It is possible to provide an implementation work item determining unit that determines the maintenance work items to be performed based on the frequency of the maintenance work items, the latest execution time, and the scheduled execution time when the maintenance work is scheduled. It is.

More specifically, for example, based on the frequency of implementation and the latest implementation time, the above-mentioned recommended work item determination unit recommends that it is desirable to perform the next maintenance work for each maintenance work item. It is possible to adopt a mode in which the maintenance work items to be performed are determined based on the relationship between the estimated recommended execution time and the scheduled execution time. In addition, when the scheduled implementation time is at or beyond the recommended maintenance time for a maintenance work item, the maintenance work item can be regarded as an implementation work item. If the time is before the recommended time for performing the maintenance work item but exceeds the time set back from the recommended execution time, the maintenance work item can be set as the work item to be performed.

The support system of the present invention can be, for example, a system having a hardware configuration centered on a support device mainly composed of a computer. In this case, the “maintenance work plan creator” is configured to include the CPU, RAM, ROM, etc. of the computer, which perform data processing, arithmetic processing, etc., and a program for executing those processing.

The degree of the size of obstacles that would occur if not performed, etc.), etc., and it is possible to adopt one or more of them as work needs. Prioritize work items that require high work A mode for creating a plan to be implemented (including a mode in which the order of work is prioritized in the maintenance work of 1), and selecting work items that have the same level of work necessity and creating a plan for those selected items Various aspects, such as an aspect of creation, are included in the present aspect.

(11) The maintenance work plan creator creates a maintenance work plan for at least one of a plurality of maintenance personnel scheduled to perform maintenance work in the component mounting system. The maintenance work support system for a component mounting system according to any one of the above modes (1) to (10), including a workforce planning unit.

The mode described in this section is, in a nutshell, a mode in which a work plan is prepared for each maintenance staff. For example, when there are a plurality of maintenance work items for a plurality of maintenance targets, it is often difficult for a certain maintenance staff to select his / her own work items. According to this aspect, a work plan is created for one maintenance staff to be created, and the maintenance staff can work according to the plan, so that efficient maintenance work is realized. . The term “maintenance personnel” is a concept that includes not only operators who actually perform maintenance work, but also administrators who manage maintenance.

(12) The personnel plan creation unit has a personnel attribute dependence plan creation unit that creates a maintenance work plan based on the personnel attributes defined for each of the at least one maintenance staff (11). The maintenance work support system for the component mounting system described in the section.

The aspect described in this section is an aspect in which when creating a plan for each of the above maintenance personnel, based on the attributes set for each of the maintenance personnel, a work plan for the maintenance personnel is created. included. As described below, “personnel attributes” include the technical level, occupation, work speed, and range of responsibilities, as well as when the maintenance staff can or cannot work, and what can or cannot be maintained. Various types are included, such as the type of one, and one or two or more of them can be adopted. According to this aspect, it is possible to create an appropriate plan according to the individual abilities of the maintenance personnel, the suitability of each individual, the restrictions imposed on each individual, and the like. Noh. Note that the personnel attributes may be determined each time a plan is created, or may be fixedly set in advance. In the case where it is set in advance, for example, in the support system, the set personnel attribute is associated with the personnel data associated with the maintenance personnel (may be a part of the maintenance data, or may be different from the maintenance data. (May be data), and a maintenance work plan may be created based on the personnel data held by the holding unit.

(13) The staffing plan creation unit creates a maintenance work plan based on at least one of the staffing attributes selected from the technical level, occupation, working speed, and range of assignment. The maintenance work support system for the component mounting system described in 12).

The mode described in this section is a mode in which personnel attributes are further limited to specific ones. The “technical level” means the technical ability, qualifications, etc. of the maintenance staff. As an aspect based on the technical level, for example, based on the relationship between the maintenance work items described above and the work skill level, the maintenance staff can use It is possible to adopt a mode of selecting a possible work item and creating a work plan for the selected work item. The “occupation” means the position of the maintenance staff, the department, the distinction between the implementer and the manager, and the like. The form based on the occupation is, for example, a work plan for the implementer, work for the manager Various plans according to the purpose of use of the plan, such as a plan, can be created. The term "work speed" refers to a value indicating the ability of the maintenance staff to perform the work individually, for example, the time required to complete the work for the maintenance work in general or for the maintenance work of a specific item. As a mode based on the work speed, it was planned that many maintenance work items would be assigned to personnel with a high work speed and few maintenance work items would be assigned to those with a low work speed. Can be adopted. In addition, the “responsibility range” means, for example, the type of maintenance target to be assigned, the name of a working machine group such as a line, an area in a factory, and the like. To select maintenance targets or work items included in the range, and work plan for the selected maintenance targets or work items. Can be adopted.

(14) The maintenance data holding unit includes, as the maintenance data, at least one of the maintenance work items included in the data, and a required time, which is a required time of the maintenance work, which is a required time.

The maintenance work support system for a component mounting system according to any one of the above 13).

The mode described in this section is, in simple terms, a mode in which a work plan is created with reference to the required maintenance work time determined for each maintenance work item. For example, when the work items to be performed are determined, it is possible to estimate the maintenance work execution time, and conversely, when the maintenance work execution time is scheduled, The maintenance work items that can be performed at time 內 can be estimated. According to this aspect, for example, it is possible to create a plan in consideration of the time load of maintenance work and the like.

(15) The maintenance work support system for a component mounting system according to mode (14), wherein the required time dependence creating unit creates a plan for completing the maintenance work within a scheduled work time.

The mode described in this section is one mode of creating a work plan based on the required work time, and is a mode of creating a work plan that fits within the scheduled work time when maintenance work can be performed. . For example, in the case of daily maintenance, and in the case of maintenance performed at the time of setup change when the production target is changed, the time for maintenance work may be limited. In this case, according to the support system of this aspect, it is possible to create a work plan including appropriate maintenance work items that can be performed by maintenance personnel. In addition, `` the scheduled work time j may be a preset time, for example, as is the case for many regular maintenances, and is performed when the operation is stopped due to an unexpected situation. As with most maintenance, the scheduled time can be set each time maintenance work is scheduled to be performed. (16) The required time dependent creation unit creates a plan in which the time for performing the maintenance work of each of the plurality of maintenance personnel of the plurality of maintenance personnel is averaged ( The maintenance work support system for a component mounting system according to the paragraph (14) or (15).

The aspect described in this section is one aspect of creating a work plan based on the required work time. For example, in a maintenance work performed during a period, a work plan that equalizes the load of multiple maintenance personnel Is included. According to this aspect, it is possible to create a work plan in which equity between maintenance personnel is ensured. In addition, when the operable time is determined, when a plurality of maintenance personnel perform work at one time, a work plan that can carry out more work items can be easily created by considering the plurality of personnel as a whole. it can. If a higher level of maintenance management is to be achieved, for example, search for a mode in which the above-mentioned work required time is retained as the time for each maintenance worker and a work plan is created based on the required work time for each maintenance worker. It is also possible.

(17) The maintenance work support system updates at least one of the required time provision items held in the maintenance data holding unit based on the actual work time of the performed maintenance work. The maintenance work support system for a component mounting system according to any one of paragraphs (14) to (16), including a time updating unit.

The mode described in this section is a mode in which the required work time, which is a reference, is updated in the creation of a picture based on the required work time. Specifically, this aspect includes, for example, an actual work time acquisition unit that acquires the actual work time, and the work required time update unit performs the update process based on the actual work time acquired by the acquisition unit. can do. In this case, the actual work time for each maintenance work item performed by each maintenance staff may be obtained.In addition, the total actual work time for each maintenance staff at one time may be obtained for each maintenance work at one time. The total actual time for the target is obtained, and the actual time for each maintenance work item is estimated from the obtained total actual time by some kind of arithmetic processing (for example, statistical or analytical processing). Update processing may be performed based on the estimation result. The time required for maintenance work may decrease as the maintenance personnel become more proficient in the work, or may increase as the maintenance target becomes older. According to this aspect, for example, a more efficient work plan can be created by flexibly responding to a change in work required time due to such factors. Note that the update process may simply replace the immediately preceding actual value, or may be a value obtained by performing some kind of arithmetic processing, such as the average value of the actual values within the latest fixed period or a certain number of times. Update processing may be performed based on the above.

In the above, each functional unit provided in the maintenance work plan creating unit has been described in the above sections. If these functional parts are enumerated, they are: maintenance target plan preparation part, work equipment group plan preparation part, non-mounting required key part plan preparation part, regular plan preparation part, irregular plan preparation part, work part. The attribute-dependent operation planning section, the personnel-based plan creation section (including the personnel attribute-based plan creation section), and the required time-dependent plan creation section. When the support system of the present invention is mainly configured by a device mainly composed of a computer, the maintenance work plan creation unit is a part that performs arithmetic processing such as the CPU of the computer in terms of hardware. Therefore, in many cases, the above-described functional units do not become independent units. In other words, each of the above functional units means that the functions of the maintenance work plan creating unit are viewed from various angles. Then, each functional unit may be arbitrarily combined with a plurality of functional units to create a plan for one or more maintenance operations. In other words, the maintenance work plan creator can exercise one or more arbitrarily selected functions to create one or more maintenance work plans.

For example, a scheduled maintenance work plan for a group of implements, where one of a number of maintenance personnel (including persons with different technical levels) assigned to the group can perform the scheduled work. Considering the case where a work plan that can be worked in time is created, in such a case, among the above functional units, a work equipment drop plan creation unit, a periodic plan creation unit, and a work attribute-based work creation plan. Department, personnel planning section

Or a part for giving a command to the work plan notifying part to select a work plan to be notified based on information on the input part 168 (including the input device, etc.) of the support device 20; The plan creation instructing unit 172 makes the maintenance work plan creating unit 142 create the timing and timing of the creation based on the setting information set by itself or the information from the input units 166 and 168. This part indicates the type of the plan. The mounting information acquisition unit 174 is a unit that receives, from the terminal device 144, the mounting information as to whether or not the component is mounted on the work equipment 10, and the performance information acquisition unit 176 is a unit for performing maintenance work. This part receives the result information from the terminal device 144 or the like. The information received by these is used for updating the data contents of the database section 140 and the like. In particular, the actual work acquisition unit 178 provided in the actual information acquisition unit 176 is a part that acquires the actual work time, and the acquired actual work time is recorded in the work required time update unit 180. It is used to update the required work time stored in the database section 140. work The history creation section 182 creates history information based on information received from the terminal device 144 and the like and information held in the database section 140 (including updating of data in the database section 140). I do. The created history information can be represented by the display units 158 and 162. The functions of these functional units will be described later in more detail.

The database section 140 has four data storage sections: maintenance data storage section 190, personnel data storage section 1992, work equipment / component data storage section 194, and plan data storage section 196. ing. The maintenance data holding section 190 implements a work item-specific work item master file 200 0 that stores data on maintenance work items for each type of mounting-related work device 10 (managed separately as a component. ), An element-specific work item master file 2022 that stores data on maintenance work items for each type of component that is managed separately, and mounting-related work machines located in the component mounting system. Maintenance work history for each work item for each work item (work record) A work history file for each work item for work equipment that stores data (excluding those managed separately as components) Maintenance work history (work results) data for each component and each work item to be performed. Contents that a have a work image file 2 0 8 image data for graphics table Shimesuru is stored. In addition, the personnel data holding unit 192 has a personnel master file 210 in which the personnel data for each maintenance person is stored. Work equipment layout master file 2 1 2 that stores data related to grouping of 10 2, Data indicating whether or not a separately managed component is mounted on any of the related work equipment 10 Is stored in the component mounting state file 2 14. Further, the plan data holding unit 196 has a creation work plan file 216 storing various maintenance work plans created by the maintenance work plan creation unit 142.

Figures 6 to 13 schematically show the data contents of each of the above-mentioned files (excluding the creation work plan file). The data contents of each file will be described with reference to these figures. The work item-specific work item master file 2000 is subject to maintenance. Data is stored for each type of a certain mounting-related work machine 10. In detail, for each type, in association with [work item name], [work frequency], [work skill level], [importance], [required time], [required material], [display] Image data name] is stored. In more detail, for each item, [Work item name] stores the data of the item name of the maintenance work performed on the mounting related work machine 10 of that type, and [Work frequency] contains Data on how many days, weeks, or months maintenance work should be performed on the work item is stored. [Working skill level] includes the working skill level (corresponding to the technical level of maintenance personnel, which will be described later) that can perform maintenance work on the work item, and H and low technical level that indicate high technical level. It is stored as the value of L. [Importance] indicates the degree of malfunction (a type of work necessity) that occurs when maintenance work is not performed on the work item. In the figure, these are marked with a () mark). In [Required time], a standard value of the time from the start of the maintenance work of the work item to the end thereof is stored. In [Required materials], the maintenance materials necessary for performing the maintenance work of the work item (for example, the names of the equipment used in the maintenance work and the supply members such as oils are stored. As will be described, in the present embodiment, the contents of the work can be displayed in a draftic manner for each work item to the maintenance staff, and the displayed image is created in [display image data name]. The data such as [work skill level], [importance], and [necessary materials] are data indicating the nature, characteristics, characteristics, etc. of the maintenance work. There is data indicating the work attributes of the maintenance work for each work item.Each work item included in the work item master file 200 for each work machine is Since each of these work items is a work item for which one of the above work attributes is specified, it is considered as an attribute-defined maintenance work item. The data on the required time is recorded as [time required], and it is regarded as a time required maintenance work item.

The one shown on the front side in Fig. 6 relates to the general-purpose mounting machine 1 Od. is there. As described above, since the general-purpose mounting machine 10d is configured by combining a plurality of modules (the mounting module 52 and the base module 50), the other mounting-related working machines 10d Unlike the data for each work machine, the data in the work item master file 200 for each work machine for the general purpose machine 100d is strictly data for each work machine and for each module. It has been. In the present embodiment, even such data for each work machine and each module is used as data for each work machine.

The element-specific work item master file 202 shown in FIG. 7 stores data on components that are specially managed at the maintenance target, that is, components that perform maintenance work even when they are not mounted. In the present embodiment, a detachable mounting head and a feeder (the mounting head 74 and the feeder 56 of the general-purpose mounting machine 10d) are set as separate management components. The contents of [work item name] to [display image data] are the same as those of the work item master file 200 for each work machine, and the description is omitted. It should be noted that what is shown on the front side in the figure is data on a certain type of mounting head 74 mounted on the mounting module 52 of the general-purpose mounting machine 10d.

In the history file 204 for each work item for each work machine shown in Fig. 8, data on the history (a set of maintenance work results) for each work item for each work machine 10 (not for each type) is recorded. Have been. The mounting-related work machine 10 is provided with an ID for each work machine, and the data of the history file 204 for each work item with respect to the work machine is data associated with the work machine ID. [Work item name] is as described above, and the maintenance work performed in the past is recorded for each work item. [Implementation date] indicates the time (year, month, and day) when the maintenance work was performed on the work item, and [Judgment] indicates the defect information on the relevant maintenance spot discovered during the maintenance work at that time. Yes (X is recorded if a defect is found, and 〇 if not found). Also,

[Implementation date] and [Judgment] are shown in the order from the present for clarity in the figure ([Implementation date 2] and [Judgment 2] are performed before [Implementation date 1] and [Judgment 1]). ), And [Implementation Date 1] indicates the latest implementation date. In addition, shown on the front side of the figure Similar to the work item-specific work item master file 200, the data described above relates to the general-purpose mounting machine 100 d and is data for each mounting module 52. The handling of this data is the same as the extraction in the case of the work item master file 200 for each work machine.

The history file 206 for each work item for each element shown in FIG. 9 records data on the history of each work item for each component (not for each type) of another management component. Each mounting head feeder is provided with an ID, and the data of the history file 206 for each element work item is data associated with the ID. The items of [work item name], [execution date], and [judgment] are the same as in the case of the previous work item-specific work item history file 204, and the description thereof is omitted. The data shown in the front of the figure is data on a certain type of mounting head 74 mounted on the mounting module 52 of the general-purpose mounting machine 10d. In the work content image file 208 shown in Fig. 10, maintenance personnel understand the contents of the maintenance work for each type of work-related work equipment 10 and the component to be maintained and for each work item. Image data for displaying images that are easy to read is recorded. Although the data structure is omitted in the figure, this data is processed by the display unit 158 of the terminal device 144, and the display unit 158 displays the maintenance procedure, points, etc. An image or video is displayed. The name of the data of the work content image matches the display image data name included in the data of the work item master file 200 for each work machine and the work item master file 202 for each element described above, and both data Are related by their names.

The personnel master file 210 shown in FIG. 11 records data on all the maintenance personnel 40 involved in the component mounting system and related to maintenance work. Each data item is associated with [personnel name]. The [employee code] is personal identification information, which is input when the maintenance staff logs in to the terminal device 144. In the support system, the employee code is unified in the terminal device 144 The display contents of the terminal device 144 and the commands for operating the support system from the input unit 166 of the terminal device 144 are automatically selected even if they are appropriate for the maintenance staff. ing. [Technical level] is the maintainer It can be thought that it indicates the high maintenance skills of the maintenance staff. Operators and maintenance technicians, except for maintenance management personnel, are set up.Maintenance technicians with high maintenance skills are considered to be maintenance staff with a high technical level of 40, and work with a high level of work skills described above. It is possible to perform both maintenance work on items and low work items. Conversely, operators with low technical skills are required to perform only low-technical skills and maintenance work according to their own skill levels. In this embodiment, three types of [occupation] are set: an operator 40c, a maintenance technician 40b, and a maintenance management staff 40a. The technician 40 b is the maintenance staff 40 who performs the actual maintenance work. [Responsibilities] indicates the range of responsibilities of the personnel, that is, in the present embodiment, the work equipment group 14 in charge of the personnel. In the present embodiment, the operator 40c is assigned to the operator himself / herself. One group of the plurality of implementation-related work machines 10 is set, and the maintenance engineer 40b is assumed to be in charge of a plurality of work machine groups 14. The data in the [technical level], [occupation type], and [teacher] items indicate the personnel attributes of each maintenance person.

The work implement arrangement master file 2 12 shown in FIG. 12 stores data indicating which work implement group 14 each implement-related work implement 10 belongs to. In other words, one [work equipment ID] is assigned one [placement group name (for example, “G 1” means the first drop)]. By referring to this data file, a maintenance work plan for each work machine group 14 will be created. The component mounting state file 2 14 shown in FIG. 13 stores information on whether or not the separately managed component described above is mounted on the mounting-related work machine 10. If a component with a certain component ID is installed, the item of [Install / Uninstall] for that component is set to "installed"; otherwise, it is set to "non-installed". If mounted, the work equipment ID of the mounted work equipment is recorded. In the figure, the actual data is recorded on the mounting head of the general-purpose mounting machine 10 d 7 4. The module ID of the mounted module 52 to which 74 is attached is also recorded. The support device 20 is configured to include the above-described functional blocks. However, as will be described later, the support device 20 can perform various types of maintenance work according to the purpose of maintenance and the like. It is possible to create a plan. Therefore, from a different perspective, the maintenance work plan creator 144 will exert different functions depending on the type of plan created. In other words, the maintenance work plan creator 144 can be thought of as including a plurality of parts exhibiting different functions. FIG. 14 shows another functional block diagram of the maintenance work plan creation unit 142, which expresses such an idea.

Based on the above concept, the maintenance work plan creation unit 144 is divided into the following functional units: maintenance target plan creation unit 220, work equipment group creation unit 222, non-mounting Element plan creator 2 24, Periodic plan creator 2 26, Irregular plan creator 228, Work attribute dependent plan creator 230, Personnel plan creator 2 32 (Personnel attribute dependent plan creator 234), and a time-dependent plan creation unit 236.

To briefly describe each of the above functional units, the maintenance target plan creation unit 220 is a part that exhibits a function of creating a plan for each maintenance target, and the work equipment group creation unit 22 It is a part that demonstrates the function of creating a plan for each work machine group 14 of the mounting-related work machine 10, and the non-mounted element plan creation unit 2 24 has been removed from the mounting-related work machine 10. This is a part that has the function of creating a maintenance work plan for the non-wearing element 18 that is a component. In addition, the periodic plan creation unit 226 is a part that exhibits a function of creating a plan of maintenance work to be performed periodically, and the irregular schedule creation unit 228 is not operating the maintenance target. This part performs the function of creating a plan for maintenance work to be performed at irregular times. Further, the work attribute dependency plan creation unit 2 2 4 is a part that exhibits a function of creating a work plan based on data on work attributes. It is the part that performs the function of creating a plan. In addition, the personnel planning section 2 3 2 It has a participant attribute-dependent plan creation section 234 as a part that demonstrates the function of creating a work plan for each of the personnel. Furthermore, the required time dependent plan creation unit 236 is a part that exhibits a function of creating a work plan based on the required work time for each maintenance work item. The specific functions performed by each of these functional units will be described later in detail in an example of creating a work plan.

The support device 20 performs various support processes, such as maintenance work plan creation and work plan notification, by executing a maintenance work support program stored in its own hard disk. The maintenance work support program includes a main routine and various routines executed under the execution of the main routine, and the various routines are executed according to various processes performed by the support device 20. It is selected and executed, so that each of the above functional parts functions.

As described above, the maintenance work plan is created based on the instructions of the plan creation instructing unit 1772. The plan creation instructing unit 172 is configured to issue an instruction to create a plan for periodic maintenance to the maintenance work plan creating unit 142. The plan creation instruction section 17 2 has data for that purpose. For example, in this component mounting system, it is determined that daily maintenance should be performed as regular maintenance, and the data related to this is the group name of a work machine group 14 that performs daily maintenance and the daily maintenance of that group 14 (For example, 15 minutes from Tuesday to Friday, 25 minutes on Monday). In addition, the plan creation instructing unit 17 2 also manages the temple B. Before the daily operation start time of the component mounting system, the daily execution of each work machine group 14 should be performed on that day. An instruction to create a maintenance work plan is given to the maintenance work plan creation unit 144. In addition, irregular maintenance, for example, when a certain work equipment group 14 is forced to stop production due to some cause (such as a failure of a certain mounting-related work equipment or unexpected circuit component shortage). It is designed to be able to cope with maintenance and the like using the non-production time. Specifically, maintenance The information including the group name of the work equipment group 14 performing the maintenance and the scheduled execution time of the maintenance is input by the non-performing personnel 40 as information indicating that the irregular maintenance is to be performed. When the information is entered in step 6, an instruction is issued to the maintenance work plan creation unit 142 to create a maintenance work plan based on the information.

i) Preparation of work equipment group plan

The process of creating a maintenance work plan based on the instructions of the plan creation instruction unit 17 2, which is performed by the maintenance work plan creation unit 14 2, will be described taking the maintenance work plan for each work machine group 14 as an example. I do. The creation process is performed by executing the work equipment group maintenance plan creation routine, which is a part of the maintenance work support program described above. Figure 15 shows a flowchart of the work equipment group maintenance plan creation routine. Hereinafter, a specific description will be given along the flowchart.

First, in step 1 (hereinafter abbreviated as “s i”, the same applies to other steps), mounting-related work machines 10 included in a work machine group 14 for creating a plan are specified. Specifically, based on the data stored in the work equipment layout master file 2 12 shown in Fig. 12, implementation-related work equipment 10 whose placement group name is the group name for which the plan is to be created is extracted. Then, the work machine ID of each of the work machines 10 is specified. Then, based on the component mounting state file 2 14 shown in FIG. 13, from among the separately managed components (feeder 56 and mounting head 74), the work machine ID is used as a key first. The component mounted on the specified mounting-related work machine 10 is specified by the component ID. These identifications are performed by the maintenance object selection unit 148.

Next, in S2, the maintenance staff 40 performing the maintenance work, specifically, the maintenance staff 40b and 40c are specified. Specifically, based on the personnel master file 210 shown in Fig. 11, the maintenance personnel 40 b and 40 c whose responsibilities are assigned to the work equipment group for which the plan is to be created. Specified by employee code.

In S3, a provisional maintenance work item to be performed is specified. More specifically, first, the history file 204 for each work item with respect to the work equipment and the history file 206 for each work item with respect to the work unit shown in FIGS. 8 and 9 are referred to. Using the work implement ID and the component ID as keys, all maintenance work items related to the implement-related work implement 10 and the components specified in S1 are extracted. Next, using the work equipment name (module name) or the component element name and the work item name as keys, the latest execution time of the maintenance work of each extracted work item (the date described in the section of [Work Date 1]) ) And the execution frequency data of the work item master file 200 for each work equipment and the work item master file 202 for each element shown in FIGS. 6 and 7. The recommended time for the work item (the next time it is desirable to do it) is calculated. Next, the calculated recommended execution time of each work item is compared with the scheduled execution time of the maintenance work, and the work items that become the recommended execution time at the scheduled execution time (recommended execution time and scheduled execution time are compared with each other). Are selected on the same day or the recommended work time exceeds the scheduled work time), and the selected work item is set as the work item that is scheduled to be implemented (tentatively scheduled work item) for the time being. Specified.

In S3 above, the work item that is the recommended implementation time at the scheduled implementation time is set as the temporary implementation work item. Identification under such conditions is suitable for regular maintenance such as daily maintenance. However, for example, in the case of irregular maintenance work, if the production stoppage takes a long time, the scheduled maintenance work time can be set relatively long. In that case, it may be desirable to carry out maintenance work on more items. In such a case, instead of the above condition, for example, a specific condition may be adopted such that even a work item reaching a recommended execution time one week later is specified as a tentatively scheduled work item.

Next, in S4, a work item having a high skill level, which is considered to have a high work skill level, is selected from the identified provisionally scheduled work items. Specifically, work items whose work skill level is “H” in the work item master files 200 and 202 are selected.

In S5, the work plan for the selected high-level work items is Created. In this embodiment, since the maintenance work of the high technical level can be performed only by a person with a high technical level, the maintenance technology of the maintenance personnel 40b and 40c specified in S2 is required. A preliminary plan will be prepared for the scope in which the project 40b is feasible. In principle, the range of responsibilities of the maintenance technician 40 b so that the total required time of the high-technical level work items of the work equipment group 14 does not exceed the work time that the maintenance technician 40 b can perform. Here, in order to simplify the explanation, all the high-technical level work items selected in S4 can be performed by the specified maintenance technician 40b. Treat as The adjustment in the case where the operation cannot be performed may be performed in accordance with the process of creating a maintenance work plan for the operator 40c described later, and the description thereof will be omitted. In addition, the work plan prepared in S5 preliminarily has work items ordered in such a way that work items are used as keys and timely priority is given to items with higher importance. Is done.

Next, in S6, a low-technical-level work item with a low work level is selected from the provisionally-scheduled work items specified in S3. Specifically, work items whose work skill level is "L" in the above work item master files 200 and 202 are selected.

Subsequently, in S7, the total required work time of the selected low-technical work items is estimated. Specifically, using the work machine name (module name) or the component name and the work item name as keys, it is selected based on the work time data in the work item master files 200 and 202. The required time of the low-technical work items is added up, and the total required time is estimated.

Next, in S8, the low-tech work items to be performed are adjusted based on their importance. In the present embodiment, it is assumed that the operator 40c plays a central role in performing maintenance work at a low technical level, and the total work scheduled time of the operator 40c (instructed by the plan creation section 1772). The adjustment is made in S8 in consideration of the case where the scheduled execution time and the number of operators 40c) exceed the total required work time. Although detailed explanations of the adjustment conditions are omitted, concretely, first, the work equipment name (Module name) or the component name and work item name are used as keys. Based on the importance data in the item master files 200 and 202, work items with high importance are specified preferentially, and after assigning work items with high importance, sufficient time is available. In some cases, work items that are to be implemented are identified and adjusted so that less important work items are additionally specified within the total scheduled work time. If the total scheduled work time does not exceed the total work required time, all the selected low-technical-level work items are specified as work items to be performed.

At S9, work items of low technical level specified to the extent practicable are allocated to each maintenance staff 40, specifically, each operator 40c. The detailed description of the allocation conditions is omitted, but specifically, the allocation is performed so that the maintenance work time of each operator 40c is averaged. At this time, in consideration of the workability of maintenance, the specified low-technical-level maintenance work items are specified so that the maintenance work of one mounting-related work machine 10 can be completed by one operator 40c as much as possible. Is allocated.

Then, in S10, a work plan of a low technical level is determined. Specifically, plan data including work items to be carried out by each operator 40c is stored in the created work plan file 2 16 in association with the staff name and the employee code of each operator 40c. This establishes a maintenance work plan for each operator 40.

In the next S11, the high-technical work plan prepared in S5 is adjusted and confirmed. Specifically, low-technical work items that have not been included in the plan due to time constraints are added to the high-technical work plan. As explained earlier, the maintenance technician 40 b is assigned a range of responsibilities so that there is enough time for maintenance work, and plays a role as a buffer for low-tech maintenance work. . Detailed explanation of the additional conditions is omitted, but the time required for maintenance work by the maintenance technician 40b is calculated based on the time required for each of the low-technical work items that were not included. As long as the time is not exceeded, it can be incorporated into a high-tech maintenance work plan. All planned low-technological work items are If the work plan is already included in the work plan in S8, or if there is not enough time in the high-tech work plan created in S5, the adjustment in S11 will be performed. I can't. In S 11, the planning data including the work items to be performed by the maintenance technician 40 b is created in a state where the planning data is associated with the personnel names and employee codes of the maintenance technician 40 b, and the work plan file 2 16 The maintenance work plan for the technician 40b is determined by being stored in the.

At S12, a maintenance work plan for each mounting-related work machine 10 is determined. More specifically, all work items included in the high-technical and low-technical level maintenance work plans determined in SIO and S11 are divided into implementation-related work machines 10 By being stored in the created work plan file 2 16, the work plan for each execution-related work 10 constituting the work equipment group 14 to be planned is determined. .

As described above, the creation of the maintenance work plan for one work machine group 14 is completed by the processing in S1 to S12. The work items to be executed are determined by the processes in S3 to S11, and the executed work item determination unit 152 is configured to include a part for performing a series of these processes. The above-mentioned processes of S1 to S12 are performed by the maintenance work plan creating unit 142, but since a series of these processes creates a maintenance work plan of one work machine group 14, the That is, the part that executes these processes functions as the work equipment group plan creation unit 222. In addition, in the above series of processes, both a regular plan and an irregular plan can be created based on the instruction of the plan creation instructing unit 172, and S 1 to S 12 The part that executes the functions of the regular plan generator 226 and the irregular plan creator 228 also functions.

In addition, in the above series of processes, a plan is created based on the work skill level of each maintenance work item, especially S4, S5, etc., and based on importance, such as S8, etc. Have a plan. For this reason, the part that executes the above series of processing constitutes the work attribute dependence plan creation unit 230. In addition, through the above series of processing, maintenance personnel 40 b and 40 c A work plan has been prepared, and the plan for each of the personnel 40 Ob and 40 c is based on the technical level of each of the personnel 40 b and 40 c. The part that executes the processing constitutes the personnel plan creation unit 232 and the personnel attribute dependence plan creation unit 234. Furthermore, the maintenance work planning process for each of the personnel 40b and 40c is set to be within the scheduled work time of each of the personnel 40b and 40c, starting with S9. In preparing the plan, processing is performed based on the time required for each work item. Therefore, the part that executes such processing constitutes the required time dependent plan creation unit 236. In preparing the work plan for the operator 40c, a process is performed in S9 so that the work time of each operator 40c is averaged. In S12, since the maintenance work plan creation processing for each mounting-related work machine 10 is performed, the maintenance target plan creation unit 2220 includes a part for executing such processing. It can be said that is constituted.

ii) Preparation of non-mounted element plan

The support system according to the present embodiment is configured such that, when the feeder 56 and the mounting head 74, which are separately managed components, are removed from the mounting-related work machine 10, In the component yard, these maintenance work can be performed. More specifically, the maintenance technician 40 b, who is the maintenance staff 40, is responsible for assuring that when the work machine group 14 in charge is in production operation, the mounting-related work machines 1 belonging to those work machine groups 14 Since the maintenance work cannot be performed for 0, the maintenance staff is required to have sufficient time. Therefore, the maintenance work of the non-mounted element 18 is performed using the extra time. For example, if a maintenance technician 40 b decides to perform maintenance work on the non-mounted element 18, the technician 40 b will use the monitoring device 2 located in the component storage 16. From 2b, the fact and the work time that can be performed are input, and the support device 20 is requested to create a plan. The input information is received by the work plan instructing unit 172, and based on the information, instructs the maintenance work plan creating unit 142 to create a work plan for the maintenance engineer 40b. Maintenance work plan creation department receiving instructions 1 4 2 Executes the non-installed element maintenance plan creation routine and creates its work plan. FIG. 16 shows a flowchart of a non-mounting element maintenance plan creation routine, which is a part of the maintenance work support program executed by the support device 20, and the creation process will be described below accordingly.

In preparing the anti-wear element plan, first, in S 21, the non-wear element 18 is selected. Specifically, based on the component mounting state file 2 14 shown in Fig. 13, maintenance of non-mounted elements 18 that are not mounted on any of the mounting-related work machines 10 is performed. Is selected for scheduled maintenance. The processing in S21 is executed by the non-mounting element selection unit 150 included in the maintenance target selection unit 148.

Next, in S22, provisional maintenance work items to be performed are identified. More specifically, similarly to the above-described S3, first, the history file 206 for each work item corresponding to the element shown in FIG. 9 is referred to, and from the data, the S2 1 All the maintenance work items related to the non-wearing element 18 specified in are extracted. Next, using the component name and the work item name as keys, the most recently performed maintenance work for each extracted work item, and the execution frequency data in the work item master file 202 shown in FIG. Based on, the recommended execution time for each extracted work item is calculated. Next, by comparing the calculated recommended execution time of each work item with the scheduled execution time of the maintenance work (often today's date), the work item with the recommended execution time at the scheduled execution time is selected. Then, the selected work item is specified as a tentatively scheduled work item.

In S23, the non-attached elements 18 are prioritized based on the urgency. Specifically, the non-mounting element 18 having a large provisional work item that exceeds the recommended implementation time at the scheduled implementation time is regarded as a non-mounting element 18 with a high urgency (a certain non-mounting element 18 The urgency of the non-mounting element 18 is determined by the degree of the work item that has exceeded the recommended execution time the most, and the non-mounting element 18 is prioritized in order of the magnitude of the degree. It is.

In the next S24, an adjustment is made based on the required work time. Specifically, the element-specific work item master file 202 is used as a key with the component name and the work item name as keys.
