[Operations during normal operation of electronic component mounting machines]
Next, the movement of the electronic component mounting machine 2 during normal operation will be described. In FIG. 3, the schematic diagram in the process 2nd step of the modules 201-204 of the electronic component mounting machine 2 of the operating condition display system 1 of this embodiment is shown. In FIG. 4, the schematic diagram in the process 3rd stage of the modules 201-204 is shown. In FIG. 5, the schematic diagram in the process 4th stage of the modules 201-204 is shown. In FIG. 6, the schematic diagram in the process 5th step of the modules 201-204 is shown.

  In the following schematic diagram, for convenience of explanation, the fact that the electronic component mounting operation in the module 201 has been completed is indicated by the solid line rising left slanting line “\” on the circuit board. On the circuit board, a solid line rising right diagonal line “/” indicates that the electronic component mounting operation in the module 203 is completed, and on the circuit board, a solid horizontal line “−” indicates that the electronic component mounting operation in the module 204 is completed. A solid vertical line “|” is shown on the circuit board.

  In the first stage of processing, as shown in FIG. 2, first, the circuit board bx1 is carried into the work area x of the module 201 from the screen printing machine as the previous process. Similarly, the circuit board by1 is carried into the work area y of the module 201 from the screen printing machine that is the previous process. Next, the head h of the module 201 mounts the electronic components A, B, and C on the circuit board bx1 in the work area x. After mounting, the head h moves from the work area x to the work area y. Further, the circuit board bx1 moves to the work area x of the module 202 via the conveyor cx.

  In the second stage of processing, as shown in FIG. 3, the head h of the module 202 mounts the electronic components D, E, and F on the circuit board bx1 in the work area x. After mounting, the head h moves from the work area x to the work area y. Further, the circuit board bx1 moves to the work area x of the module 203 via the conveyor cx.

  Further, the head h of the module 201 mounts the electronic components A and B on the circuit board by1 in the work area y. After mounting, the head h moves from the work area y to the work area x. The circuit board by1 moves to the work area y of the module 202 via the conveyor cy.

  In the third stage of processing, as shown in FIG. 4, the head h of the module 203 mounts the electronic components G, H, and I on the circuit board bx1 in the work area x. After mounting, the head h moves from the work area x to the work area y. Further, the circuit board bx1 moves to the work area x of the module 204 via the conveyor cx.

  Further, the head h of the module 202 mounts the electronic components D and E on the circuit board by1 in the work area y. After mounting, the head h moves from the work area y to the work area x. Further, the circuit board by1 moves to the work area y of the module 203 via the conveyor cy. Further, the circuit board bx2 of the module 201 is subjected to the same process as the first process stage.

  In the fourth stage of processing, as shown in FIG. 5, the head h of the module 204 mounts the electronic components J, K, and L on the circuit board bx1 in the work area x. After mounting, the head h moves from the work area x to the work area y. Further, the circuit board bx1 moves to the work area x (not shown) of the module 205 (not shown) via the conveyor cx (not shown).

  Further, the head h of the module 203 mounts the electronic components G and H on the circuit board by1 in the work area y. After mounting, the head h moves from the work area y to the work area x. The circuit board by1 moves to the work area y of the module 204 via the conveyor cy. Further, the same processing as the second step is performed on the circuit board by2 of the module 201 and the circuit board bx2 of the module 202.

  In the fifth stage of processing, as shown in FIG. 6, the head h of the module 204 mounts the electronic components J and K on the circuit board by1 in the work area y. After mounting, the head h moves from the work area y to the work area x. Further, the circuit board by1 moves to the work area y (not shown) of the module 205 (not shown) via the conveyor cy (not shown). Further, the same processing as the third step is performed on the circuit board bx3 of the module 201, the circuit board by2 of the module 202, and the circuit board bx2 of the module 203. Thereafter, the fourth stage of processing and the fifth stage of processing are alternately performed, so that electronic components are continuously mounted on the circuit board.

  Here, for example, when attention is paid to the module 202, as shown in FIG. 5, the head h is mounted on the work area y while the head h mounts the electronic components D, E, and F on the circuit board bx2 of the work area x. The circuit board by2 to be processed next is carried in. Further, as shown in FIG. 6, while the head h mounts the electronic components D and E on the circuit board by2 in the work area y, the circuit board bx3 to be processed next by the head h is carried into the work area x. Has been.

  Thus, while each module 201-204 is mounting an electronic component on the circuit board of one work area (for example, work area x) among the work areas x and y, the other work area (for example, work area y). ) Contains a circuit board to be processed next. For this reason, the circuit board transport time is apparently zero.

[Motion of electronic component mounting machine when circuit board stays]
Next, the movement of the electronic component mounting machine when the circuit board stays will be described. In FIG. 7, the schematic diagram in the residence 1st stage of the modules 201-204 of the electronic component mounting machine 2 of the operating condition display system 1 of this embodiment is shown. In FIG. 8, the schematic diagram in the stay 2nd stage of the modules 201-204 is shown. In FIG. 9, the schematic diagram in the residence 3rd stage of the modules 201-204 is shown.

  When the processing stage further advances from the state shown in FIG. 6 by one stage, the state shown in FIG. 7 is obtained. Here, when the stock of the electronic component F of the module 202 is exhausted, the processing for the circuit board bx3 in the module 202 is stopped. For this reason, the processing on the upstream side of the circuit board bx3 in the lane X is congested. That is, the circuit board is not supplied to the work area x after the module 203.

  By the way, the electronic component F is not mounted on the circuit boards by2, by3, and by4 flowing in the lane Y. For this reason, even if the stock of the electronic component F runs out, the processing in the lane Y can proceed. Accordingly, the head h of the module 202 moves from the work area x to the work area y while stopping the processing of the circuit board bx3. Then, as shown in FIG. 8, the electronic components D and E are mounted on the circuit board by3 that flows through the lane Y.

  Even after the electronic parts D and E are mounted, the head h of the module 202 does not return to the work area x. The reason is that, since there is no electronic component F, the circuit board bx3 cannot be processed even when returning to the work area x. Therefore, as shown in FIG. 9, the head h of the module 202 waits for the next circuit board by4 in the lane Y in the work area y. As described above, the circuit boards bx3 and bx4 flowing through the lane X stay, and the electronic components A, B, D, E, G, H, J, and K are mounted only on the circuit boards by2, by3, and by4 flowing through the lane Y. Is done. As described above, when the retention of the circuit board occurs, the number of produced circuit boards decreases.

[Motion of electronic component mounting machine when overtaking circuit board]
Next, the movement of the electronic component mounting machine when overtaking the circuit board will be described. In FIG. 10, the schematic diagram in the overtaking 1st step of the modules 201-204 of the electronic component mounting machine 2 of the operating condition display system 1 of this embodiment is shown. In FIG. 11, the schematic diagram in the overtaking second stage of the modules 201-204 is shown. In FIG. 12, the schematic diagram in the overtaking 3rd stage of the modules 201-204 is shown. FIG. 13 shows a schematic diagram of the modules 201 to 204 in the overtaking fourth stage. In FIG. 14, the schematic diagram in the overtaking 5th stage of the modules 201-204 is shown.

  When the processing stage further advances from the state shown in FIG. 6 by one stage, the state shown in FIG. 10 is obtained. The head h of the module 202 has electronic components D, E, and F mounted on the circuit board bx3 in the order of electronic component D → electronic component E → electronic component F. Here, when the stock of the electronic component E is exhausted, the head h of the module 202 interrupts the mounting of the electronic component E and shifts to the mounting of the electronic component F. When the mounting of the electronic component F is completed, the processing of the circuit board bx3 is stopped. By the way, the circuit board by3 is carried into the work area y of the module 202 from the module 201. Therefore, as shown in FIG. 11, the head h of the module 202 moves from the work area x to the work area y and mounts the electronic component D on the circuit board by3. When the mounting of the electronic component D is completed, the processing of the circuit board by3 is stopped because there is no stock of the electronic component E.

  In this way, the electronic component E is mounted on both the circuit boards bx2, bx3, bx4 flowing through the lane X and the circuit boards by2, by3, by4, by5 flowing through the lane Y. For this reason, the flow of both lanes X and Y stays.

  In this state, when the electronic component E is replenished to the module 202, the head h of the module 202 resumes the processing of the circuit board by3 in the work area y as shown in FIG. That is, the head h starts to mount the electronic component E from the circuit board by3 instead of the circuit board bx3 in the work area x. When the processing of the circuit board by3 is completed, the circuit board by3 is transferred to the module 203 as shown in FIG. On the other hand, the head h mounts the electronic component E on the circuit board bx3 in the work area x. After that, as shown in FIG. 14, the normal operation is restored, and in each of the modules 201 to 204, circuit boards bx2, bx3, and bx4 that flow through the lane X and circuit boards by2, by3, by4, and by5 that flow through the lane Y Are alternately processed.

  As described above, when the stock of the electronic component E is exhausted, the electronic component mounting process that has been performed in the order of lane X → lane Y → lane X → lane Y is performed in the order of lane X → lane Y → lane X → lane. The order changes as Y → lane Y → lane X → lane Y. That is, the process for the circuit board in lane Y is continuously executed. For this reason, the circuit board by3 in the lane Y passes the circuit board bx3 in the lane X. When the overtaking of the circuit board occurs, as shown in FIG. 13, “empty” occurs in the work area x of the modules 203 and 204. The “vacant” shifts downstream along the flow of the circuit board. However, the “vacant space” is never filled. As described above, when overtaking of a circuit board occurs, the number of produced circuit boards decreases.

[Operation status display method]
Next, the operation status display method of this embodiment will be described.

《How to read the screen display》
First, how to display the screen on the display device 31 of the computer 3 of the operating status display system 1 of the present embodiment will be described. In FIG. 15, the screen of the display apparatus 31 of the computer 3 of the operation status display system 1 of this embodiment is shown. FIG. 16 shows an enlarged view in a circle XVI in FIG. FIG. 17 shows an enlarged view in a circle XVII in FIG. FIG. 18 shows an enlarged view in a circle XVIII in FIG.

  As shown in FIGS. 15, 16, 17, and 18, the module axis is displayed on the vertical axis of the screen. All modules 201 to 220 are listed on the module axis. A time axis (time) is displayed on the horizontal axis of the screen. For each module 201-220, a number of arrows bx, by are displayed in two upper and lower stages. Arrows bx and by extend in parallel to the time axis. Arrows bx and by represent the processing time of the circuit board. That is, the beginning (left end) of the arrows bx and by represents the processing start time, and the end (right end) of the arrow represents the processing completion time. Of the two upper and lower stages, the upper part represents the work area x and the lower part represents the work area y. That is, among the two upper and lower arrows bx and by, the upper arrow bx represents a circuit board flowing through the lane X, and the lower arrow by represents a circuit board flowing through the lane Y. In addition, a status bar Z is displayed at the upper level of the two upper and lower arrows bx and by.

  16, 17, and 18, in the status bar Z, a 45 ° oblique hatching to the right indicates the processing state Z1, a vertical hatching represents the waiting for the subsequent process Z2, and a 30 ° oblique hatching to the right represents the parts supply waiting state Z3. The horizontal line hatching indicates the waiting for the previous process Z4. Note that, on the actual screen of the display device 31, the status is displayed not by hatching but by color.

  Here, the processing state Z1 refers to a state in which each of the modules 201 to 220 has a predetermined electronic component mounted on a circuit board. Post-process waiting Z2 refers to a state in which an arbitrary n-th module is waiting for the n + 1-th module on the downstream side to be free. In the case of the module 220 on the most downstream side, it means a state waiting for the reflow device to become free. The component replenishment waiting state Z3 refers to a state in which an electronic component that has run out of stock is being replenished. The pre-process waiting Z4 refers to a state in which an arbitrary n-th module is waiting for the arrival of a circuit board from the n-1th module on the upstream side. In the case of the module 201 on the most upstream side, it means a state waiting for the arrival of the circuit board from the screen printer.

  As shown in a circle XVI (see FIG. 16), in the module 207, there is a section in which the arrow bx includes the arrow by. In the section, the arrow bx is arranged on the left side of the arrow by when the start ends are compared, while the arrow bx is arranged on the right side of the arrow by when the ends are compared. This section means that in the module 207, the circuit board by has completed the process first, even though the circuit board bx has started the process first. From this, the operator can visually recognize that the circuit board has been overtaken as shown in FIGS. 10 to 14 in the module 207 at about 13: 8 to 13: 9. it can.

  As shown in a circle XVII (see FIG. 17), in the modules 208, 209, and 210, a horizontal line hatching section exists in the status bar Z. From this, the worker can visually recognize that there is a waiting for the previous process Z4 at about 13:12 to 13:13 in the modules 208, 209, and 210. In addition, as indicated by a one-dot chain line in FIG. 17, by comparing the modules 208, 209, and 210, the operator can visually recognize that the downtime due to the previous process waiting Z4 is gradually eliminated.

  As shown in a circle XVIII (see FIG. 18), in the module 219, there is a section where the arrow by is not found and only the arrow bx is continuous. From this, in the work area y of the module 219, the worker confirmed that the circuit board stayed as shown in FIGS. 7 to 9 at about 13: 9 to 13:11. It can be visually recognized.

<< Processing flow for operating status display method >>
Next, the flow of processing of the operation status display method of this embodiment will be described. FIG. 19 shows a flowchart of the operation status display method of the present embodiment. After startup (S1), event information (for example, status report, processing start, processing completion, etc.) is sent from any module 201-220 to the input device of the computer main body 30 shown in FIG. (Circuit board clamping start, completion, recipe switching, etc.)) is input (S2). The storage device of the computer main body 30 stores the input event information, the modules 201 to 220 to which the event information is transmitted, and the lanes X and Y (S3). Whether the event information is status information (for example, error, power off, network connection disconnection, waiting for a post process, waiting for parts replenishment, waiting for a pre process, etc.) (S4) It is determined whether the information is processing start information of the circuit board in 201 to 220 (S9) or information of processing completion of the circuit board in the module 201 to 220 (S12).

  When the event information is status information (S4), the discriminating device of the computer main body 30 changes the drawing color of the status bar Z according to the status type, as shown by various hatchings in FIGS. 16, 17, and 18. Determine (S5). Then, the discriminating device of the computer main body 30 calculates the elapsed time by obtaining the difference between the time when the new state is entered and the time when the previous state is entered (stored in the storage device) (S6). Then, the determination device of the computer main body 30 draws the status bar Z on the screen of the display device 31. Specifically, the modules 201 to 220 that have stored the status bar Z for the elapsed time calculated in step 6 (S6) in the time axis direction from the coordinates indicating the immediately previous time, stored in step 3 (S3), Drawing is performed at the positions of lanes X and Y in the color determined in step 5 (S5) (S7). Then, the storage device of the computer main body 30 stores the new state for each of the modules 201 to 220 and the lanes X and Y (S8). The state stored in step 8 (S8) is used as the “previous state” in step 6 (S6) at the next drawing.

  When the event information is a process start (S9), the determination device of the computer main body 30 is the position of the modules 201 to 220, lanes X and Y stored in step 3 (S3), and the event occurrence time. A processing start point is drawn at the coordinates indicating (S10). Then, the storage device of the computer main body 30 stores the processing start point for each of the modules 201 to 220 and the lanes X and Y (S11).

  When the event information is processed (S12), the determination device of the computer main body 30 stores the modules 201 to 220, the positions of the lanes X and Y stored in step 3 (S3), and the storage in step 11 (S11). The immediately preceding processing start point is acquired from the storage device (S13). Then, an arrow is drawn from the processing start point acquired in step 13 (S13) to the coordinates indicating the processing completion time (S14). Here, during the period from the start of the process to the completion of the process, there is an abnormality (for example, when a process that exceeds (or below) a certain percentage of the scheduled processing time, such as disposal of electronic components, circuit board transfer retry, etc.) If it has occurred (S15), an arrow is drawn in a color indicating the occurrence of an abnormality (S16).

  When the event information is other (S17), the determination device of the computer main body 30 determines the event occurrence time at the positions of the modules 201 to 220, lanes X and Y stored in step 3 (S3). A mark (for example, ○, ×, *, etc.) is drawn at the indicated coordinates.

[Function and effect]
Next, the operational effects of the operating status display system, operating status display method, and operating status display program of this embodiment will be described. According to the operating status display system, operating status display method, and operating status display program of this embodiment, the processing time of the circuit board can be displayed for each of the modules 201 to 220 and for each of the lanes X and Y. In addition, the processing time of the circuit board can be displayed in time series. For this reason, according to the operating status display system, operating status display method, and operating status display program of the present embodiment, the flow of the circuit board in the electronic component mounting machine 2, that is, when passing through all the modules 201 to 220, is shown in the previous figure. From the screen display of the display device 31 shown in FIG.

  Further, according to the operating status display system, the operating status display method, and the operating status display program of this embodiment, event information can be displayed on the screen in association with the modules 201 to 220 and the lanes X and Y. For this reason, it is possible to easily grasp which module 201 to 220 the event information relates to which lanes X and Y.

  Further, according to the operating status display system, the operating status display method, and the operating status display program of the present embodiment, the status of the modules 201 to 220 and the information related to the processing time of the circuit board can be simultaneously displayed on the screen. For this reason, it is easy to grasp the relationship between the statuses of the modules 201 to 220 and the processing start time and processing completion time of the circuit board.

  Also, according to the operating status display system, operating status display method, and operating status display program of this embodiment, how the circuit board processing start time and processing completion time change according to the status types of the modules 201-220. Easy to figure out what to do.

  Further, according to the operating status display system, operating status display method, and operating status display program of the present embodiment, event information of all modules 201 to 220 can be displayed in time series. For this reason, it is easy to visually recognize the flow of the circuit boards in all the modules 201 to 220.

  Further, according to the operating status display system, operating status display method, and operating status display program of the present embodiment, event information can be stored in the storage device of the computer main body 30 for a predetermined time. For this reason, the event information for the predetermined time can be drawn on the screen at a predetermined time. In addition, event information can be drawn on the screen little by little in real time.

  Further, in the case of the screen display of the operation status display system of the conventional electronic component mounting machine shown in FIG. 20, even if a trouble occurs, the influence of the trouble on the downstream processing unit is unknown. On the other hand, in the case of the operating status display system, operating status display method, and operating status display program of this embodiment, as shown in FIG. 15 and FIG. 17, troubles occur in the modules 201 to 220 on the downstream side. The effect can be visually recognized. For this reason, the discriminating device of the computer main body 30 can calculate the production amount when it is assumed that the trouble does not occur, and compare the production amount with the actual production amount. And the magnitude of the influence which the said trouble has on production can be judged. Therefore, it is possible to set priorities for dealing with various troubles based on the magnitude of the influence on production. For example, if a trouble that has a small impact on production and a trouble that has a large impact on production occur at the same time, priority is given to the trouble that has a large impact, thereby minimizing the impact on production. it can.

  Before mounting electronic components on a circuit board, as shown in FIG. 2, the electronic component A is a module 201, the electronic component K is a module 204, and the like. It is necessary to sort them in advance. The reason is to make the processing load of each module 201-220 as constant as possible. However, in reality, it is difficult to make the processing loads of the modules 201 to 220 constant. Modules 201 to 220 that become bottlenecks appear.

  However, in the case of the screen display of the operation status display system of the conventional electronic component mounting machine shown in FIG. 20, it is difficult to specify the modules 201 to 220 that are bottlenecks. On the other hand, according to the operation status display system, the operation status display method, and the operation status display program of this embodiment, the flow of the circuit board is obvious. For this reason, the modules 201-220 which become a bottleneck can be specified easily. Therefore, it is possible to accurately and easily perform the work of distributing the electronic components to the modules 201 to 220.

  Moreover, in the case of the electronic component mounting machine 2, compared with a machine tool, the number of modules 201-220 (the number of processes) tends to increase. Further, in the case of the electronic component mounting machine 2, the inside of the modules 201 to 220 is difficult to visually recognize because the electronic component itself is small and hates dust. On the other hand, the number of workers arranged is often small. For this reason, it is extremely difficult for an operator to manage the modules 201 to 220 arranged in a line in the factory one by one (there may be a larger number of modules) one by one and grasp the flow of the circuit board.

  In this regard, according to the operating status display system, operating status display method, and operating status display program of the present invention, as shown in FIG. 15, the flow of circuit boards in all modules 201 to 220 is displayed on the screen of the display device 31. Can be displayed. Therefore, the operating status display system, operating status display method, and operating status display program of the present invention are particularly suitable for use for mounting electronic components.

<Others>
The embodiment of the operating status display system, operating status display method, and operating status display program of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.

  For example, in the above-described embodiment, the operation status display system, the operation status display method, and the operation status display program of the present invention are used for mounting electronic components, but may be used for machine tools and other production facilities. Good.

  In the above embodiment, the number of lanes X and Y is two, but the number of lanes may be three or four or more. In the above embodiment, the number of modules 201 to 220 is twenty, but the number of modules 201 to 220 may be larger.

  Moreover, in the said embodiment, although the modules 201-220 which perform the same process were arranged in a line as a process unit of this invention, you may arrange the process unit which performs a different process in a line. In the above embodiment, as shown in FIG. 15, the processing time is expressed by a single-ended arrow, but the processing time may be expressed by a double-ended arrow, a straight line, a bar, or the like. It is only necessary that the processing start time and the processing completion time can be visually recognized.

  In the processing flow of the operation status display method of the above embodiment, event information in a predetermined section may be drawn in a lump. In this case, the operator first inputs the start time and end time of the display section using the keyboard of the computer 3 in FIG. Next, in step 2 (S2) of FIG. 19, event information that occurred between the start time and the end time is read from the storage device of the computer main body 30 in chronological order. And the process after step 3 (S3) is performed with respect to the read event information. When the processing after step 3 (S3) for the last event information in the time series order (event information within the display section and closest to the end time) is completed, the drawing process is terminated.

  Further, when trouble occurs, the flow of the circuit board when it is assumed that there is no trouble may be displayed on the screen. For example, when it is assumed that the previous process waiting Z4 in FIG. 17 has not occurred, there is no contradiction in the flow of the circuit board (for example, the arrows bx and by do not overlap in time series) The status bar Z may be displayed left justified for the previous process waiting Z4. This makes it easier for the operator to visually recognize the influence of the trouble.
