Embodiments for Carrying Out the Invention

[0010] The worker support system of the present disclosure is a worker support system for supporting the management of a worker's work, and includes an acquisition unit that acquires identification information indicating a worker to be managed, proficiency information indicating the proficiency level of each worker with respect to the work to be managed, and importance information indicating the importance of the work; and an arithmetic processing unit that determines a work instruction screen to be displayed on a display unit based on the proficiency information corresponding to the worker indicated by the identification information and the importance information.

[0011]

[0012] According to this, since the work instruction screen displayed on the display unit is determined based on the proficiency information and the importance information, it is possible to display a screen corresponding to the proficiency for each of the workers with different proficiency levels, and it is also possible to prevent overlooking the work instructions for important work. For this reason, it is possible to suppress the occurrence of work mistakes while suppressing a decrease in work efficiency.

[0013]

[0014] ​​Further, the importance information may be set based on the occurrence status of defects in the work.

[0015] According to this, it is possible to increase the importance of work where defects are likely to occur and decrease the importance of work where defects are unlikely to occur.

[0016] Further, the importance information may be set for each worker based on the occurrence status of defects in the work for each worker.

[0017] According to this, since the work that is likely to cause defects and the work that is unlikely to cause defects may differ depending on the worker, the importance can be set for each worker according to the occurrence status of defects for each worker.

[0018] Further, the worker support system may further include an input unit that receives an input of the importance information.

[0019] According to this, the importance can be set manually.

[0020] Further, the arithmetic processing unit may determine the screen so that the amount of information of the work instruction displayed on the display unit decreases as the proficiency indicated by the proficiency information increases. For example, at least a work instruction for the work with the highest importance may be displayed on the display unit.

[0021] According to this, since the amount of information of the work instruction displayed on the display unit decreases as the proficiency increases, it is possible to suppress a decrease in the work efficiency of a worker with a high proficiency. In addition, since a work instruction for a work with a high importance (for example, a work instruction for the work with the highest importance) can be displayed, it is possible to suppress the occurrence of work mistakes.

[0022] Further, when the proficiency indicated by the proficiency information is equal to or higher than a predetermined value, the arithmetic processing unit may determine the screen so that a work instruction for the work with a high importance is displayed on the display unit more prominently than a work instruction for the work with a low importance.

[0023] According to this, when the proficiency level is high, work instructions for important tasks are emphasized and displayed, so that it is possible to suppress the occurrence of work mistakes due to skipping. Also, since it is only necessary to intensively check the emphasized work instructions, it is less likely to take time to check the work instructions, and it is possible to suppress a decrease in the work efficiency of highly proficient workers.

[0024] Further, the arithmetic processing unit may determine the screen so that a button for skipping work instructions for some of the plurality of work contents in the work procedure of the work is displayed on the display unit when the proficiency level indicated by the proficiency information is equal to or higher than a predetermined level.

[0025] According to this, when the proficiency level is high, a button for skipping some work instructions is displayed, so that highly proficient workers can skip work instructions that do not require confirmation, and it is possible to suppress a decrease in the work efficiency of highly proficient workers. Also, by preventing work instructions for important tasks from being skipped, it is possible to suppress the occurrence of work mistakes.

[0026] Further, the arithmetic processing unit may set or change the work instructions skipped by the button based on the work schedule of the worker.

[0027] According to this, at the start of work after a break, at the time of shift change from day shift to night shift or from night shift to day shift, or at the start of work after a lunch break, etc., since workers may forget the work content or become slack, it is possible to reduce the work instructions to be skipped at such times.

[0028] Further, the arithmetic processing unit may set or change the work instructions skipped by the button based on the occurrence status of defects in the work.

[0029] According to this, it is possible to prevent work instructions for tasks where defects are likely to occur from being skipped, and to make it possible to skip work instructions for tasks where defects are less likely to occur.

[0030] Further, the arithmetic processing unit may set or change, for each operator, a work instruction skipped by the button based on the occurrence status of defects in the work for each operator.

[0031] According to this, since the work that is likely to cause defects and the work that is less likely to cause defects may differ depending on the operator, it is possible to set or change, for each operator, the work instruction to be skipped according to the occurrence status of defects for each operator.

[0032] Further, the operator support system may further include an input unit that receives an input of a work instruction skipped by the button.

[0033] According to this, it is possible to manually set or change the work instruction skipped by the skip button.

[0034] Further, the operator support system may further include an output unit that outputs an operation history of the operator on the display unit. For example, the operation history may include the presence or absence of an operation of the button or the operation time or operation time of the display unit.

[0035] According to this, it is possible to determine the work instruction to be skipped or determine the proficiency level based on the operation history such as the presence or absence of an operation of the skip button or the operation time or operation time of the display unit.

[0036] The operator support method of the present disclosure is an operator support method for assisting in the management of an operator's work, and includes acquiring identification information indicating the operator to be managed, proficiency information indicating the proficiency level of each operator with respect to the work to be managed, and importance information indicating the importance of the work, and determining a screen of a work instruction to be displayed on a display unit based on the proficiency information corresponding to the operator indicated by the identification information and the importance information.

[0037] According to this, it is possible to provide a worker support method that can suppress the occurrence of work mistakes while suppressing a decrease in work efficiency.

[0038] Note that each of the embodiments described below shows comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps, order of steps, etc. shown in the following embodiments are examples and are not intended to limit the present disclosure.

[0039] (Embodiment) Hereinafter, embodiments will be described with reference to FIGS. 1 to 11B.

[0040] FIG. 1 is a configuration diagram showing an example of a component mounting system 1 according to an embodiment. The component mounting system 1 is an example of a worker support system. The worker support system includes at least an acquisition unit and an arithmetic processing unit, and these components may be distributed and arranged in a plurality of devices within the worker support system, or may be arranged in one device. Hereinafter, an example in which the component mounting devices M4 and M5 in the component mounting system 1 include an acquisition unit and an arithmetic processing unit will be described. Note that the worker support system may not be a system composed of a plurality of devices, but may be a single device. For example, the worker support system may be the management device 3 or the component mounting devices M4 and M5 in the component mounting system 1.

[0041] The component mounting system 1 is a system having a function of mounting electronic components on a substrate to produce a mounted substrate. In the present embodiment, a configuration is adopted in which a plurality of component mounting lines 4 are connected to the management device 3 via a communication network 2, and workers 5 assigned to each component mounting line 4 execute various operations for device operation. At this time, the portable terminals 6 possessed by the respective workers 5 are used as needed. The operations on each component mounting line 4 are managed by the management device 3. That is, data necessary for the operation of each facility belonging to the component mounting line 4 is transmitted by the management device 3 to each facility, and the operation results by each facility are transmitted to the management device 3.

[0042] The component mounting line 4 is configured to connect a substrate supply device M1, a substrate transfer device M2, a solder printing device M3, component mounting devices M4, M5, a reflow device M6, and a substrate recovery device M7 in series. The substrate 13 (see FIG. 2) supplied by the substrate supply device M1 is carried into the solder printing device M3 via the substrate transfer device M2, and a solder printing operation is performed here to screen-print solder for component bonding on the substrate 13.

[0043] The substrate 13 after solder printing is sequentially transferred to the component mounting devices M4 and M5, and a component mounting operation is performed here to mount electronic components on the substrate 13 after solder printing. Then, the substrate 13 after component mounting is carried into the reflow device M6, where it is heated according to a predetermined heating profile, and the solder for component bonding melts and solidifies. As a result, the electronic components are solder-bonded to the substrate 13, and a mounted substrate with electronic components mounted on the substrate 13 is completed and recovered by the substrate recovery device M7.

[0044] FIG. 2 is a partial cross-sectional view showing an example of the component mounting devices M4 and M5 according to the embodiment, and shows a cross-section of the main part of the component mounting devices M4 and M5. In FIG. 2, a substrate transfer mechanism 12 is disposed on the base 11 in the substrate transfer direction (X direction: perpendicular to the paper surface in FIG. 2). The substrate transfer mechanism 12 transfers the substrate 13 carried in from the solder printing device M3 and positions and holds it at the mounting operation position by the component mounting mechanism 17. The component mounting mechanism 17 is configured such that the mounting head 19 with the suction nozzle 20 mounted at the lower end is horizontally moved in the X direction and the Y direction by the head movement mechanism 18.

[0045] On the side of the substrate transfer mechanism 12 in the Y direction (the direction orthogonal to the X direction in the horizontal direction), a component supply unit 14 is arranged. In the component supply unit 14, a carriage 21 with a plurality of tape feeders 15 pre-mounted on a feeder base 21a is set. The position of the carriage 21 in the component supply unit 14 is fixed by clamping the feeder base 21a to a fixed base 11a provided on the base 11. The carriage 21 holds supply reels 22 that respectively store carrier tapes 23 holding electronic components in a wound state. The carrier tape 23 pulled out from the supply reel 22 is pitch-fed by the tape feeder 15 to the component pick-up position by the suction nozzle 20.

[0046] A component recognition camera 16 is disposed between the component supply unit 14 and the substrate 13. The mounting head 19 that picks up an electronic component from the tape feeder 15 by the suction nozzle 20 moves above the component recognition camera 16, and the electronic component held by suction on the suction nozzle 20 is imaged by the component recognition camera 16.

[0047] In the component mounting system 1, various operations are performed by the operator 5 for the above-described component mounting devices M4 and M5. FIG. 3 is a diagram for explaining an example of an operation targeted in the component mounting system 1 according to the embodiment, and shows an example of a tape splicing operation that is executed when a component shortage occurs in the component supply unit 14 and the supply reel 22 needs to be replaced among the operations executed by the operator 5. FIG. 3(a) shows the flow of the tape splicing operation, and FIG. 3(b) shows the operation specifically executed.

[0048] As shown in Fig. 3(a), when the operation starts (ST1), first, the operator 5 reads the old part ID (ST2). As shown in Fig. 3(b)(i), at that time, the already mounted carrier tape 23A connected to the tape feeder 15 is wound and stored, and the supply reel 22A in the state of being set on the cart 21, that is, the barcode 24 (old part ID) attached to the old part reel, is read using the barcode reading function of the portable terminal 6. Next, the operator 5 reads the new part ID (ST3). As shown in Fig. 3(b)(ii), the new supply reel 22B carried in for part replenishment, that is, the barcode 24 (new part ID) attached to the new part reel, is similarly read using the barcode reading function of the portable terminal 6.

[0049] Then, the new part ID and the old part ID read in (ST2) and (ST3) are collated. Here, if the collation result matches, the new supply reel 22B is determined to be the correct supply reel 22 that supplies the specified parts to the tape feeder 15, and the splicing operation is executed (ST4). That is, as shown in Fig. 3(b)(iii), the trailing end of the carrier tape 23A and the leading end of the carrier tape 23B are butted against each other, and both are bonded together with the splicing tape 25.

[0050] At this time, while adjusting the alignment in the tape length direction of the carrier tapes 23A and 23B, the carrier tapes 23A and 23B are joined together in a state where the interval between the part pockets at the butting portion is adjusted, and thus the tape joining operation ends (ST5). By performing such a tape joining operation, it is possible to perform part replenishment without stopping the operation of the apparatus.

[0051] In order to arrange conditions such that the operator 5 can accurately execute the above-described tape joining operation and the like in the component mounting apparatuses M4 and M5, it is necessary to develop a system that appropriately supports the management of the operator 5's work. In the present embodiment, the support required for such management of the operator's work is realized by an operator support system having the configuration described below.

[0052] FIG. 4 is a block diagram showing an example of the configuration of the control systems of the component mounting devices M4 and M5 that constitute the component mounting system 1 according to the embodiment, and extracts the components related to the above-described operator support system from the configurations of the component mounting devices M4 and M5. In FIG. 4, a control unit 30 that controls the component mounting devices M4 and M5 includes an operation control unit 31, a storage unit 32, an arithmetic processing unit 33, a display unit 34, an input unit 35, an update unit 36, a warning notification unit 37, a reading unit 38, a communication unit 39, and an acquisition unit 50.

[0053] The operation control unit 31 controls the mechanism elements for executing the component mounting operation by the component mounting devices M4 and M5, that is, the substrate transfer mechanism 12, the component supply unit 14, and the component mounting mechanism 17. The storage unit 32 stores various data used for work support in addition to the mounting data (not shown) used for the control process by the operation control unit 31. These data include operator information 40, guide information 45, work result information 47, and warning information 48.

[0054] The arithmetic processing unit 33 performs arithmetic processing such as determining a screen necessary for work support for an individual operator 5 based on the data stored in the storage unit 32. The display unit 34 and the input unit 35 are both connected to the display / input panel 26, and perform display of various screens and data input and instruction input performed by the operator 5 via the display / input panel 26. Here, as the display / input panel 26, any one of the touch panel type display / input panels provided in each of the mobile terminal 6 possessed by the operator 5, the component mounting devices M4 and M5, and the management device 3 is used. Hereinafter, displaying a screen on the display / input panel 26 will also be described as displaying a screen on the display unit 34. Although details will be described later, the input unit 35 may receive input of importance information or may receive input of a work instruction skipped by a button for skipping a work instruction.

[0055] The data to be input includes identification information 41 for identifying the operator 5, and the input unit 35 inputs the identification information 41 for identifying the operator 5. Also, the screen to be displayed includes a work instruction screen for the operator 5, and the display unit 34 displays the work instruction screen for the operator 5. The update unit 36 performs processing for updating the individual data stored for each operator 5 in the storage unit 32. This update target includes proficiency information 42, which will be described later. That is, the update unit 36 updates the proficiency information 42 for each operator 5.

[0056] The warning notification unit 37 is connected to a warning lamp 27 such as a signal tower, and notifies a warning required when a predetermined event defined in the warning information 48 occurs, via the warning lamp 27. The reading unit 38 performs a process of reading an identification code (ID) such as a barcode 24 attached to the supply reel 22, based on a signal from a barcode reader 28 provided in the mobile terminal 6. The communication unit 39 is a communication interface, and performs transmission and reception of signals and data with the management device 3 via the communication network 2. Note that the communication unit 39 may perform transmission and reception of signals and data with the mobile terminal 6. For example, the communication unit 39 is an example of an output unit that outputs the operation history of the display unit 34 (display / input panel 26) by the operator 5.

[0057] Next, the data stored in the storage unit 32 will be described.

[0058] First, examples of the guide information 45 and the work result information 47 for giving work instructions to the operator 5 will be described with reference to FIG. 5.

[0059] FIG. 5 is a diagram showing an example of the guide information and the work result information in the component mounting system 1 according to the embodiment. FIG. 5(a) shows an example of the guide information 45, and FIG. 5(b) shows an example of the work result information 47.

[0060] In Fig. 5(a), the work item targeted is the "tape connection" illustrated in Fig. 3, and a plurality of work contents 45a corresponding to guide information 45(1) to guide information 45(3) are described as the work procedures for properly executing the work item. Here, as the plurality of work contents 45a in the work procedure of the work "tape connection", "reading of old parts", "reading of new parts", and "splicing" are listed.

[0061] And the appropriate time 45b for executing each of the plurality of work contents 45a is described corresponding to each of guide information 45(1) to guide information 45(3). The appropriate time 45b indicates the range of the required time allowed when an ordinary worker 5 executes each of the plurality of work contents 45a, and each worker 5 executes the work with the appropriate time 45b as the goal. By displaying the guide information 45 with such a configuration, the worker 5 can confirm the information for executing the work item to be executed by the correct work procedure when performing the work. Whether the work procedure actually executed by the worker 5 is correct or not is determined by the control unit 30 referring to the work procedure shown in the guide information 45.

[0062] Also, the guide information 45 includes importance information indicating the importance of the work to be managed (here, "tape connection"). For example, the importance information may be set for each of the plurality of work contents in the work procedure of the work. Specifically, importance information may be set for each of "reading of old parts", "reading of new parts", and "splicing" in the work procedure of "tape connection".

[0063] Also, for example, the importance information may be set based on the occurrence status of work defects. For example, for work where defects are likely to occur, a high importance may be set, and for work where defects are unlikely to occur, a low importance may be set. Note that since the work that is likely to cause defects and the work that is unlikely to cause defects may differ among workers 5, the importance information may be set for each worker 5 based on the occurrence status of work defects for each worker 5.

[0064] Further, for example, the importance information may be input via the input unit 35. That is, the importance information may be set manually.

[0065] Next, with reference to FIG. 5(b), an example of the work result information 47 will be described. The work result information 47 is data obtained by digitizing the results of the work performed by the worker 5 on the component mounting apparatuses M4 and M5. The created work result information 47 is transmitted to the management apparatus 3 via the communication unit 39, and the management apparatus 3 determines whether the work result is appropriate. Here, as the work item 47a, an example of "tape connection" shown in FIG. 3 is similarly shown, and the work performed by five workers 5 with identification information 41 being 01 to 05 and the determination results are shown in tabular form.

[0066] That is, the work results when each of the workers 5 executes steps 1 to 3 shown in the procedure 47b (corresponding to "reading of old components", "reading of new components", and "splicing", which are a plurality of work contents 45a shown in FIG. 5(a)) are displayed in the form of a pass / fail determination using ○ or ×. Note that ○ means OK and × means NG. ○ or × is determined in consideration of, for example, at least one of the required time and the presence or absence of defects. Specific examples of defects include non-matching of components for which the identification code (ID) cannot be read, breakage of the top tape where the top tapes are separated, occurrence of adsorption errors or recognition errors at a certain tape length (for example, 300 mm, etc.) before and after splicing, etc. A recognition error is an error associated with the work of the worker 5 such as inversion of the front and back of the component, chip standing, or absence of components. Also, in the result 47c, the result of comprehensively evaluating and determining the individual work results in steps 1 to 3 is similarly presented in the form of a comprehensive pass / fail determination using ○ or ×. Further, in the work time 47d, the date and time when the work was actually executed are recorded as time history data. In addition to, or instead of, "reading of old components", "reading of new components", and "splicing", the inspection result of the component mounting position may be considered for the pass / fail determination.

[0067] Note that the work result information 47 is created based on information input from the display / input panel 26 and the barcode reader 28 provided in the component mounting devices M4 and M5. For work executed without using the display / input panel 26 or the barcode reader 28, during the execution of such work, a work completion button and a work cancellation button are displayed on the display / input panel 26. When the work is completed, the worker 5 touches the work completion button on the display / input panel 26, and the control unit 30 determines that the work executed without using the display / input panel 26 or the barcode reader 28 is completed. Also, when the worker 5 determines that the work cannot be completed, by touching the work cancellation button, the control unit 30 determines that an interruption (work error) of the work executed without using the display / input panel 26 or the barcode reader 28 has occurred.

[0068] Next, the worker information 40 will be described. The worker information 40 includes identification information 41 and proficiency information 42.

[0069] The identification information 41 is information indicating the worker 5 to be managed, and is information for identifying the worker 5 working on the component mounting devices M4 and M5. For example, the worker 5 can input information for identifying himself / herself via the display / input panel 26 or the like, and the component mounting system 1 can identify the worker 5 to be managed.

[0070] The proficiency information 42 is information indicating the proficiency of each worker 5 (identification information 41) with respect to the work to be managed. The proficiency information 42 indicates the skill level in work execution of each individual worker 5, and is specifically determined based on, for example, the number of work errors or the required time for work. For example, a worker 5 with a small number of work errors or a short required time is determined to have a high proficiency, a worker 5 with a medium number of work errors or a medium required time is determined to have a medium proficiency, and a worker 5 with a large number of work errors or a long required time is determined to have a low proficiency. The proficiency information 42 is determined and updated based on the work result information 47 shown in FIG. 5(b).

[0071] FIG. 6 is a diagram showing an example of proficiency information 42 in the component mounting system 1 according to the embodiment. Proficiency information 42 as shown in FIG. 6 is stored in the storage unit 32. In the proficiency information 42 shown in FIG. 6, the proficiency of the operator 5 with the identification information 41 being 01 is 1 (for example, low), the proficiency of the operator 5 with the identification information 41 being 02 is 2 (for example, medium), and the proficiency of the operator 5 with the identification information 41 being 03 is 3 (for example, high).

[0072] The acquisition unit 50 acquires the identification information 41, the proficiency information 42, and the importance information (guidance information 45). For example, the acquisition unit 50 acquires these pieces of information from the storage unit 32. Note that these pieces of information may be stored outside the storage unit 32 provided in the component mounting apparatuses M4 and M5, and may be stored in the storage unit of the management apparatus 3 or in the cloud or the like. The acquisition unit 50 may acquire these pieces of information from the storage unit of the management apparatus 3 or from the cloud or the like.

[0073] Next, the details of the operation of the component mounting system 1 will be described with reference to FIGS. 7 to 11B.

[0074] FIG. 7 is a flowchart showing an example of the operation of the component mounting system 1 according to the embodiment.

[0075] The acquisition unit 50 acquires the identification information 41 indicating the operator 5 to be managed, the proficiency information 52 indicating the proficiency of each operator 5 with respect to the work to be managed, and the importance information indicating the importance of the work (S11).

[0076] Next, the arithmetic processing unit 33 determines a work instruction screen to be displayed on the display unit 34 based on the proficiency information 42 corresponding to the operator 5 indicated by the identification information 41 and the importance information (S12). For example, the arithmetic processing unit 33 determines the display mode of the work instruction to be displayed on the display unit 34 based on the proficiency information 42 and the importance information. The display mode is, for example, the amount of information of the work instruction to be displayed or the content of the work instruction to be displayed.

[0077] Then, the arithmetic processing unit 33 outputs the determined screen to the display unit 34 (S13).

[0078] For example, the arithmetic processing unit 33 determines a work instruction screen such that the amount of information of the work instruction displayed on the display unit 34 decreases as the proficiency indicated by the proficiency information increases. The fact that the amount of information of the work instruction displayed on the display unit 34 decreases as the proficiency increases will be described with reference to FIG. 8.

[0079] FIG. 8 is a diagram for explaining that the amount of information of the work instruction displayed on the display unit 34 decreases as the proficiency increases. In FIG. 8, as multiple work contents, "pasting new and old tapes with tape", "cutting the ends of new and old tapes", and "setting to a reel holder" are shown. Also, as a tip, "applying pressure to the tape when pasting the tape" is shown. In FIG. 8, importance information is set for each of the multiple work contents. "Pasting new and old tapes with tape" is set with a high importance, "cutting the ends of new and old tapes" is set with a medium importance, and "setting to a reel holder" is set with a low importance. Also, proficiency 1 means low proficiency, proficiency 2 means medium proficiency, and proficiency 3 means high proficiency.

[0080] As shown in FIG. 8, the higher the proficiency level, the smaller the amount of work instruction information displayed on the display unit 34. However, for example, regardless of the proficiency level, at least a work instruction regarding the work with the highest importance (here, the work instruction corresponding to "attach new and old tapes with tape") is displayed on the display unit 34. For example, for the operator 5 with a proficiency level of 1, a screen of work instructions corresponding to "attach new and old tapes with tape" with high importance, "cut the ends of new and old tapes" with medium importance, and "set on the reel holder" with low importance is displayed. Note that for the operator 5 with a proficiency level of 1, a tip such as "apply pressure to the tape when attaching the tape" is also displayed. For the operator 5 with a proficiency level of 2, a screen of work instructions corresponding to "attach new and old tapes with tape" with high importance and "cut the ends of new and old tapes" with medium importance is displayed, and a screen of work instructions corresponding to "set on the reel holder" with low importance is not displayed. For the operator 5 with a proficiency level of 3, a screen of work instructions corresponding to "attach new and old tapes with tape" with high importance is displayed, and screens of work instructions corresponding to "cut the ends of new and old tapes" with medium importance and "set on the reel holder" with low importance are not displayed.

[0081] Here, a specific example of the work instruction screen will be described with reference to FIG. 9.

[0082] FIG. 9 is a diagram showing a first example of the work instruction screen. FIG. 9 is an example of the work instruction screen when the arithmetic processing unit 33 determines the work instruction screen such that the higher the proficiency level indicated by the proficiency information, the smaller the amount of work instruction information displayed on the display unit 34.

[0083] As shown in Fig. 9(a), for the operator 5 with proficiency level 1, four work instruction screens from screen 101 to screen 104 are displayed. As shown in Fig. 9(b), for the operator 5 with proficiency level 2, three work instruction screens from screen 105 to screen 107 are displayed. As shown in Fig. 9(c), for the operator 5 with proficiency level 3, two work instruction screens of screen 108 and 109 are displayed. As shown from Fig. 9(a) to Fig. 9(c), it can be seen that the higher the proficiency level, the less the amount of work instruction information displayed on the display unit 34. For example, on screen 103 for the operator 5 with proficiency level 1, 107 for the operator 5 with proficiency level 2, and 109 for the operator 5 with proficiency level 3, there are work instructions for the most important work (work instructions for the work of pasting new tape and old tape with tape). Also, on screen 103 for the operator 5 with proficiency level 1, tips are also displayed.

[0084] In this way, since the higher the proficiency level, the less the amount of work instruction information displayed on the display unit 34, it is possible to suppress the decrease in the work efficiency of the operator 5 with a high proficiency level. Also, since it is possible to display work instructions for important work (for example, work instructions for the most important work), it is possible to suppress the occurrence of work mistakes.

[0085] Note that when the proficiency level indicated by the proficiency information is a predetermined level or higher, the arithmetic processing unit 33 may determine the work instruction screen so that the work instruction for the important work is displayed on the display unit 34 more prominently than the work instruction for the less important work. A specific example will be described with reference to Fig. 10.

[0086] Fig. 10 is a diagram showing a second example of the work instruction screen. Fig. 10 is an example of the work instruction screen when the arithmetic processing unit 33 determines the work instruction screen so that the work instruction for the important work is displayed on the display unit 34 more prominently than the work instruction for the less important work when the proficiency level is a predetermined level or higher.

[0087] As shown in Fig. 10(a), for the operator 5 with proficiency level 1, screens 201 to 204 are displayed. As shown in Fig. 10(b), for the operator 5 with proficiency level 2, screens 205 to 208 are displayed. As shown in Fig. 10(c), for the operator 5 with proficiency level 3, screens 209 to 212 are displayed. For example, assume that the work instructions for the operation of cutting the ends of the new tape and the old tape and the work instructions for the operation of pasting the new tape and the old tape with tape are more important than the work instructions for other operations. As shown in Figs. 10(a) to 10(c), when the proficiency level is a predetermined value or more (for example, the proficiency level is 2 or more), it can be seen that the work instructions for the highly important operations are displayed more prominently in the display unit 34 than the work instructions for the less important operations. For example, on screens 206 and 207 for the operator 5 with proficiency level 2, and on screens 210 and 211 for the operator 5 with proficiency level 3, the work instructions for the operation of cutting the ends of the new tape and the old tape and the work instructions for the operation of pasting the new tape and the old tape with tape are highlighted by underlining the characters. Further, on screen 211 for the operator 5 with proficiency level 3, the size of the underlined characters is increased, so that the work instructions for the operation of pasting the new tape and the old tape with tape are highlighted. Note that the way of highlighting is not limited to these, and for example, it may be performed by blinking or highlighting.

[0088] In this way, when the proficiency level is high, the work instructions for the highly important operations are highlighted and displayed, so that the occurrence of work mistakes due to skipping can be suppressed. Also, since it is only necessary to intensively check the highlighted work instructions, it is less likely to take time to confirm the work instructions, and the decrease in the work efficiency of the highly proficient operator 5 can be suppressed.

[0089] Further, when the proficiency level indicated by the proficiency information is a predetermined value or more, the arithmetic processing unit 33 may determine the screen so that a button for skipping the work instructions for a part of the plurality of work contents in the work procedure of the work is displayed on the display unit 34. A specific example will be described with reference to Figs. 11A and 11B.

[0090] FIG. 11A and FIG. 11B are diagrams showing a third example of the work instruction screen. The screen following the screen 304 in FIG. 11A(a) is the screen 305 in FIG. 11B(a), the screen following the screen 311 in FIG. 11A(b) is the screen 312 in FIG. 11B(b), and the screen following the screen 318 in FIG. 11A(c) is the screen 319 in FIG. 11B(c). FIGS. 11A and 11B are an example of the work instruction screen when the arithmetic processing unit 33 determines the screen so that a button for skipping work instructions for some of a plurality of work contents in the work procedure is displayed on the display unit 34 when the proficiency is equal to or higher than a predetermined level.

[0091] As shown in FIGS. 11A(a) and 11B(a), for the operator 5 with proficiency level 1, the screens 301 to 307 are displayed. As shown in FIGS. 11A(b) and 11B(b), for the operator 5 with proficiency level 2, the screens 308 to 314 are displayed. As shown in FIGS. 11A(c) and 11B(c), for the operator 5 with proficiency level 3, the screens 315 to 321 are displayed. As shown from FIGS. 11A(a) and 11B(a) to FIGS. 11A(c) and 11B(c), it can be seen that a skip button is displayed when the proficiency is equal to or higher than a predetermined level (for example, the proficiency is 2 or higher). For example, a skip button is displayed on the screens 308 to 311 for the operator 5 with proficiency level 2 and on the screens 315 to 319 for the operator 5 with proficiency level 3. The skip button is a button for skipping work instructions for some of a plurality of work contents. For the operator 5 with proficiency level 2, when any skip button is operated, the displayed screen is skipped to the screen 312. For example, when the skip button is operated on the screen 308, the screens 309 to 311 are not displayed and the screen 312 is displayed. Also, for the operator 5 with proficiency level 3, when any skip button is operated, the displayed screen is skipped to the screen 320. For example, when the skip button is operated on the screen 315, the screens 316 to 319 are not displayed and the screen 320 is displayed.

[0092] For example, assume that the work instruction regarding the operation of pasting a new tape and an old tape with tape is the most important, and the work instruction regarding the operation of cutting the ends of the new tape and the old tape is the next most important. As in screens 306, 313, and 320, the work instruction regarding the operation of pasting a new tape and an old tape with tape, which is the most important, is displayed without being skipped. Also, as in screens 312 and 319, the work instruction regarding the operation of cutting the ends of the new tape and the old tape, which is the next most important, is displayed without being skipped for operator 5 with proficiency level 2, but can be skipped for operator 5 with proficiency level 3. This is because it may not be important for operator 5 with proficiency level 3.

[0093] In this way, since the skip button for some work instructions is displayed when the proficiency level is high, operator 5 with a high proficiency level can skip work instructions that do not require confirmation, and it is possible to suppress a decrease in the work efficiency of operator 5 with a high proficiency level. Also, by ensuring that work instructions for important operations are not skipped, it is possible to suppress the occurrence of work errors.

[0094] Note that the arithmetic processing unit 33 may set or change the work instructions skipped by the skip button based on the work schedule of operator 5. For example, at the start of work after a break (e.g., Monday in the case of a work schedule where Saturday and Sunday are holidays), at the time of shift change from day shift to night shift or from night shift to day shift, or at the start of work after the lunch break, operator 5 may forget the work content or become complacent, so the number of work instructions to be skipped can be reduced at such times. Also, the arithmetic processing unit 33 may set or change the work instructions skipped by the skip button based on the physical condition of operator 5.

[0095] Furthermore, the arithmetic processing unit 33 may set or change the work instructions skipped by the skip button based on the occurrence status of work defects. For example, it is possible to ensure that work instructions for operations where defects are likely to occur are not skipped, and make work instructions for operations where defects are less likely to occur skippable.

[0096] Further, the arithmetic processing unit 33 may set or change, for each worker 5, a work instruction to be skipped by the skip button based on the occurrence status of defects in the work for each worker 5. For example, since the work that is likely to cause defects and the work that is unlikely to cause defects may differ depending on the worker 5, the work instruction to be skipped can be set or changed for each worker 5 according to the occurrence status of defects for each worker 5.

[0097] Also, the work instruction to be skipped by the skip button may be input via the input unit 35. For example, the work instruction to be skipped by the skip button can be manually set or changed. For example, a supervisor of the worker 5 or the like may manually set or change the work instruction to be skipped by the skip button according to the type of process, change of materials, change of equipment conditions, or maintenance time.

[0098] Also, for example, the communication unit 39 may output the operation history of the display unit 34 by the worker 5, and it is conceivable that a supervisor of the worker 5 or the like refers to the output operation history and sets or changes the work instruction to be skipped. For example, the operation history may include the presence or absence of an operation of the skip button. When a defect occurs in the work corresponding to the skipped work instruction, the work instruction can be changed so as not to be skipped. Also, for example, the operation history may include the operation time or operation time of the display unit 34. When the screen of a certain work instruction is paged quickly, it can be determined that the work instruction is not important for the worker 5, and the work instruction can be changed to a work instruction to be skipped.

[0099] In addition, the operation history of the display unit 34 by the operator 5 may be used for proficiency determination. For example, the operator 5 may perform an operation according to the work instruction while looking at the work instruction screen, and when the operation is completed, switch to the next work instruction screen and perform an operation according to the next work instruction while looking at the next work instruction screen. In this case, the operation time of the display unit 34 or the work time required for the work can be estimated from the operation time or operation time. For example, a standard work time may be set for each work according to the work instruction, and the proficiency may be determined based on the comparison result between the standard work time and the estimated work time. Note that the standard work time may be displayed on the work instruction screen, and further, the standard work time may be counted down. In addition, the current proficiency of the operator 5 may be displayed on the work instruction screen. Also, a sample of the work may be displayed on the work instruction screen.

[0100] As described above, since the work instruction screen displayed on the display unit 34 is determined based on the proficiency information and the importance information, it is possible to display a screen corresponding to the proficiency for each of the operators 5 with different proficiencies, and it is also possible to prevent the work instructions for high-importance work from being skipped. For this reason, it is possible to suppress the occurrence of work mistakes while suppressing a decrease in work efficiency.

However, the present disclosure is not limited to the above embodiments. As long as the gist of the present disclosure is not deviated from, various modifications conceived by those skilled in the art applied to this embodiment, and forms constructed by combining components in different embodiments are also included in the scope of the present disclosure.

[0102] For example, in the above embodiment, an example in which the operator support system includes an input unit that receives input of importance information has been described. However, the operator support system may not include such an input unit.

[0104] For example, in the above embodiment, an example in which the worker support system includes an output unit that outputs the operation history of the display unit 34 by the worker 5 has been described. However, the worker support system may not include such an output unit.

[0105] For example, the present disclosure can be realized not only as a worker support system but also as a worker support method including steps (processes) performed by each component constituting the worker support system.

[0106] As shown in FIG. 7, the worker support method is a worker support method for assisting in the management of a worker's work, and includes acquiring identification information indicating the worker to be managed, proficiency information indicating the proficiency of each worker with respect to the work to be managed, and importance information indicating the importance of the work (S11), and determining a screen of a work instruction to be displayed on the display unit based on the proficiency information corresponding to the worker indicated by the identification information and the importance information (S12).

And the present disclosure can be realized as a program for causing a computer to execute the steps included in the worker support method. Further, the present disclosure can be realized as a non-transitory computer-readable recording medium such as a CD-ROM on which the program is recorded.

[0108] For example, when the present disclosure is implemented by a program (software), each step is executed by using hardware resources such as a computer's CPU, memory, and input / output circuits. That is, each step is executed by the CPU acquiring data from the memory or input / output circuits or the like and performing calculations, or outputting the calculation result to the memory or input / output circuits or the like.
