Specifically, the production equipment history information 24 includes information on the production time such as the time when the board is carried in and out of each component mounting device, the time when the work on each board is started, and the time when the work is completed. , The time when the device error occurred, the time when the device error was resolved, etc. are included. Further, in the production equipment history information 24, in addition to the information for each substrate, the statistical amount obtained by statistically processing the accumulated data is stored.

Here, an example of the production equipment history information 24 will be described with reference to FIG. Here, the statistics of the production time (time per sheet required for the work on the board) for each component mounting device are shown. As statistics, maximum values, average values, and minimum values excluding outliers due to device errors and the like are stored. The statistic is not limited to the maximum value, the average value, and the minimum value, and may be the first quartile, the median, the third quartile, the standard deviation, and the like. The predicted value of the production time included in the product type information 21 is set based on the actual results of these production times. The actual production time may be set for each type of mounting board, or may be set collectively for each type of similar or all types. In addition, it may be classified and set for each element required for the work attached to the production equipment.

In FIG. 3, the worker history information 25 stores information on the worker W and the automatic guided vehicle V among the operating status of the floor F acquired by the acquisition unit 12. Specifically, the worker history information 25 includes the time when the worker W or the automatic guided vehicle V starts supplying parts to the mounting machines M3 to M6, the time when the parts are completed, the parts storage shelf 4 and the mounting machines M3 to M6. The time for moving between, the time for the worker W to respond to an error, and the like are included. Further, in the worker history information 25, in addition to the information for each event, the statistical amount obtained by statistically processing the accumulated data is stored.

Here, an example of the worker history information 25 will be described with reference to FIG. Here, the statistics of the working time of parts replenishment (working time required for one parts replenishment) to the mounting machines M3 to M6 of the workers W1 to W4 and the automatic guided vehicles V1 to V3 are shown. As the statistic, the maximum value, the average value, and the minimum value excluding the outliers are stored. The average value of the working hours of the workers W1 to W4 differs depending on the working ability of the workers W1 to W4. For example, the average time required for parts replenishment of the worker W1 having a high work ability is 53 seconds, whereas the average time of the worker W4 having a short work experience and a low work ability is 85 seconds. The predicted value of the working time included in the product type information 21 is set based on the actual results of these working hours.

The actual work time may be set for each work item, or may be set for each similar or all work items. Further, the work time required for parts supply may include the time for working at the target production facility, but may also include the travel time for moving to the target production facility.

The production planning unit 11 is on the component mounting lines L1 to L3 based on the predicted value of the production time of each component mounting device included in the product type information 21 and the predicted value of the working time of the worker W or the automatic carrier V. Create a production plan to produce the mounting board. Here, a daily production plan is created. More specifically, whether the production planning unit 11 executes production preparations such as setup changes or produces mounting boards for each time zone based on the production time and working time set based on the actual results. , When producing a mounting board, create a production plan that includes the number of production sheets for each time zone. The created production plan is stored in the production information storage unit 19 as the production plan information 22. Hereinafter, the production plan created in this way is referred to as an "initial production plan".

Here, an example of the initial production plan created by the production plan creation unit 11 will be described with reference to FIG. From 8:00 to 24:00 shown in FIG. 6, the production plan 41 is aggregated and displayed at time 40 every hour. The production plan 41 includes the types of work on the component mounting lines L1 to L3 and the required work man-hours. For example, during the time period from 8:00 to 10:00 and from 17:00 to 19:00, production preparations for changing the type of mounting board to be produced are scheduled, and the work man-hours for 1.8 man-hours are predicted at each time. The work man-hours here are represented by the work amount (man-hours) that the worker W having a standard work ability can work in one hour. At 1.8 man-hours, it is predicted that 1.8 workers W with standard work capacity will need to be assigned to work such as production preparation and parts supply for 1 hour.

In addition, it is predicted that 120 mounting boards will be produced during the time period from 10:00 to 11:00, and it is predicted that work man-hours of 0.8 man-hours will be required. Since the number of sheets produced per hour is predicted based on the average value of the actual production time, the number of sheets actually produced varies depending on the production situation at that time. In addition, the required work man-hours also vary depending on the type of spare parts, the type of device error, the frequency of occurrence, and the like.

In FIG. 3, the acquisition unit 12 acquires information on the operating status of the floor F including the actual production time of each component mounting device and the actual working time of the worker W and the automatic guided vehicle V via the communication unit 30. Then, it is stored in the production history storage unit 23. Specifically, the acquisition unit 12 acquires the history of events (board loading, unloading, work start, completion, error occurrence, resolution, etc.) that have occurred in each component mounting device, and produces the production equipment history information 24. It is stored in the history storage unit 23.

Further, the acquisition unit 12 reports the start and completion of the work by the operation panel of the device for mounting each component and the touch panel 7 of the information terminal 5 by the worker W, and starts and reports the completion of the work from the automatic guided vehicle V. Is acquired, the working time is calculated, and the working time is stored in the production history storage unit 23 as the worker history information 25. Further, the acquisition unit 12 stores the statistic calculated by statistically processing the acquired various data in the production history storage unit 23.

Here, with reference to FIGS. 6 and 7, an example of the actual production time and the actual working time acquired by the acquisition unit 12 will be described. In FIG. 6, the acquired actual production time is represented as the actual production number of the produced mounting boards. FIG. 6 shows the production results 42 from 8:00 to 15:00, which is the present time, aggregated every hour. FIG. 7 is a plan progress notification screen 50 displayed on the display unit 29 when a plan delay, which will be described later, occurs. In the actual result graph 53 displayed on the plan progress notification screen 50, the production actual result 42 from 8:00 to 15:00 at the current point is displayed as a solid line.

The production record 42 includes the type of work executed on the component mounting lines L1 to L3, the record of the number of production sheets, and the record of work man-hours. For example, production preparations are being carried out from 8:00 to 9:50, and the actual work man-hours from 9:00 to 10:00 are 1.7 man-hours, which is less than the predicted 1.8 man-hours. In addition, the actual number of sheets produced in the time zone from 10:00 to 11:00 is 60, and the line is stopped due to a device error from 10:30 to 11:00 in this time zone. Therefore, the number of sheets produced during this time period is significantly less than the planned 120 sheets.

In FIG. 3, the flow line analysis unit 13 analyzes the images in the floor F captured by the photographing devices S1 to S8 based on the floor layout information 20, identifies the worker W working on the floor F, and identifies the worker W. Determine the movement flow line and work position of the worker W. The identification of the worker W by the flow line analysis unit 13 is carried out by face recognition by image processing, recognition of a certification mark attached to a hat or work clothes worn by the worker W, and the like.

In addition, the flow line analysis unit 13 analyzes the work content from the retention position of the worker W, the movement of the hand and body, and the position of the head acquired from the video, and acquires the report from each component mounting device and the information terminal 5. Get the working time of work that cannot be done. The acquisition unit 12 adds the information acquired by the flow line analysis unit 13 to the information collected from each component mounting device and the information terminal 5, and stores it in the production history storage unit 23 as the worker history information 25. As a result, the prediction accuracy of the production plan can be improved. In this way, the photographing devices S1 to S8 and the flow line analysis unit 13 constitute an acquisition unit for acquiring information on the operating status of the floor F.

In FIG. 3, the production plan creation unit 11 is based on the operation status of the floor F including the acquired actual production time of each component mounting device and the actual work time of the worker W and the automatic guided vehicle V. Recreate the production plan after that point. In the example of FIG. 6, the production plan after 15:00, which is the current time, is recreated. Specifically, the production planning unit 11 remains at the present time based on the actual results such as the frequency of device errors of each component mounting device up to the current time and the efficiency of work such as replenishment work of the worker W. Recreate the plan to produce the number of production in the future.

That is, in the above-mentioned initial production plan, it was created based on the average value of the actual production time and working time, but the performance of the production equipment and the worker W changes depending on the maintenance and physical condition of the day. As a result, the production time and working time may fluctuate above the average value. Therefore, by recreating the production plan, a more accurate production plan can be created. The timing of recreating the production plan is arbitrary. For example, the production plan may be recreated when a specific time zone, a specific production amount, or a specific achievement level is reached, and the achievement level is the plan and the actual result. It may be recreated when the difference exceeds a specific value.

The recreated production plan is stored in the production plan information 22. Hereinafter, the production plan recreated in this way is referred to as a "recreated production plan". In FIG. 7, on the plan progress notification screen 50, following the actual graph 53, the recreated production plan graph 54 showing the recreated production plan with a dotted line after 15:00 is displayed.

In FIG. 3, the calculation unit 14 calculates the degree of achievement of the production plan at the time when the operating status of the floor F is acquired. Specifically, in the example of FIG. 7, the calculation unit 14 calculates the ratio of the number of production sheets scheduled by 15:00 to the total number of production in the initial production plan at 15:00 and the production by 15:00 to the total number of production. Calculate the ratio of the number of production sheets. In FIG. 7, the “achievement level” display frame 55 displayed on the plan progress notification screen 50 shows the achievement level (plan: 74%) in the initial production plan calculated by the calculation unit 14 and the achievement level based on the actual results. (Actual result: 69%) is displayed.

In FIG. 3, the comparison unit 15 compares the initial production plan created by the production plan creation unit 11 with the recreated production plan. For example, the comparison unit 15 compares the production completion time when the production of the mounting substrate of the total number of production sheets in the initial production plan is completed with the production completion time in the review production plan. In FIG. 7, the production completion time of the production plan graph 52 of the plan progress notification screen 50 is 24:00, and the production completion time of the recreated production plan graph 54 is 25:00.

In FIG. 3, the determination unit 16 determines whether or not there is a delay from the initial production plan (created production plan) based on the comparison result of the initial production plan and the recreated production plan. In FIG. 7, the production completion time of the recreated production plan is delayed by one hour from the production completion time of the initial production plan. The determination unit 16 makes a determination at a predetermined time such as every 30 minutes or every hour. When it is determined that the delay is delayed from the initial production plan (created production plan), the proposal unit 17 extracts the planning process that can eliminate the delay from the recreated production plan (recreated production plan) and takes countermeasures. suggest. The production plan creation unit 11 creates a revised production plan based on the proposal of the proposal unit 17. Hereinafter, the production plan reviewed in this way will be referred to as a review production plan.

The proposal unit 17 extracts and proposes a countermeasure plan that can be established from a plurality of countermeasure plans. The countermeasure plan is a plan to shorten the process time, and as a means for shortening the process time, there are methods such as increasing the production / working capacity and carrying over the work amount for the delay. Further, as an extraction method, the following methods can be mentioned. Of the planning processes of the re-creation plan, the process that can eliminate the delay time if it is performed with the minimum production time and the minimum working time is estimated and extracted.

Alternatively, in the preparation process of the re-creation plan, the available worker W or automatic guided vehicle V is extracted and changed to the worker W or automatic guided vehicle V having high work ability. , Guess the process that can eliminate the delay time and extract it. Alternatively, a production process that matches or is similar to the type of product to be delayed is extracted, the amount of work for the delay is added to the production process to determine whether the delivery date is met, and a production process that can be combined is estimated. Extract.

In FIG. 7, a review production plan graph 56 showing a review production plan is displayed on the plan progress notification screen 50. Further, in the "measure proposal" display frame 57 displayed on the plan progress notification screen 50, the measures proposed by the proposal unit 17 are displayed. In this example, the proposal unit 17 selects the preparation process as a countermeasure from the planning processes such as the production process and the preparation process. Specifically, the production preparation that was scheduled to be executed from 17:00 to 19:00 in the initial production plan is delayed from 17:30 to 19:30 in the re-creation production plan. Therefore, the proposal unit 17 proposes to increase the number of workers W from the planned two to three and shorten the preparation process. With this proposal, production preparation is expected to start at 17:30 and complete at 19:00.

In FIG. 3, the display processing unit 18 causes the display unit 29 to display the plan progress notification screen 50 when the determination unit 16 determines that the initial production plan is delayed. That is, the display processing unit 18 and the display unit 29 notify that a planned delay occurs in which the production completion time is delayed from the initial production plan when it is determined that the production plan (initial production plan) created is delayed. It is a notification unit. In FIG. 7, a warning to the effect that a delay has occurred is displayed in text on the display frame 51 displayed on the plan progress notification screen 50. In addition to the "warning", the display frame 51 may display "as planned" in text to the effect that production is proceeding as planned.

Next, along the flow of FIG. 8, on the floor F where the production equipment (device for mounting parts), the worker W, and the automatic transport vehicle V are operated by the management computer 3 (production management device) while referring to each figure. A production plan creation method for managing the production of a product (mounting board) will be described. In FIG. 8, first, the production plan creation unit 11 creates an initial production plan based on the production time and the working time set in the product type information 21 (ST1: initial production plan creation process).

When the production of the mounting board starts on the component mounting lines L1 to L3, the acquisition unit 12 sets the component mounting device (production equipment) on the board (work) based on the data transmitted from each component mounting device and the information terminal 5. ), And the information on the operating status of the floor F including the actual working time when the worker W or the automatic carrier V performs the work related to the component mounting device is acquired (ST2: Operating status). Acquisition process). Further, in the operation status acquisition step (ST2), the flow line analysis unit 13 analyzes the images in the floor F captured by the photographing devices S1 to S8 to acquire the working time of the worker W.

In FIG. 8, the process ends when all the planned mounting boards are produced (Yes in ST3). When the production is continued (No in ST3), the calculation unit 14 calculates the achievement level of the initial production plan at the time when the operation status of the floor F is acquired in the operation status acquisition process (ST2) (ST4: achievement level). Calculation process). In the example of FIG. 7, the achievement level at 15:00, which is the current time, is calculated. Next, the production plan creation unit 11 recreates the production plan (creates the recreated production plan) based on the actual production time and the actual work time acquired in the operation status acquisition process (ST2) (ST5: recreate). Production planning process).

Next, the comparison unit 15 compares the created production plan (initial production plan) with the recreated production plan (recreated production plan) (ST6: comparison process), and the determination unit 16 makes an initial production plan based on the comparison result. It is determined whether or not there is a delay (ST7: determination step). If there is no delay from the initial production plan (No in ST7), the process returns to the operation status acquisition process (ST2) and the acquisition of the operation status of the floor F is continued.

In FIG. 8, when it is determined that the initial production plan is delayed (Yes in ST7), the display processing unit 18 causes the display unit 29 to display the plan progress notification screen 50 (see FIG. 7), and the plan delay occurs. Notify that (ST8: delay notification process). The notification of the plan delay is not limited to the display of the plan progress notification screen 50 on the display unit 29. For example, the notification may be performed by the information terminal 5 possessed by the administrator or the worker W, or may be notified by the information display device (andon) installed on the floor F. Further, since the delay may be naturally eliminated while the production is continued, it is not necessary to immediately execute the delay notification step (ST8) even if the delay is confirmed in the comparison step (ST6), and it is not necessary to immediately execute the delay notification step (ST8). 30 minutes) If the delay is continuously confirmed, the delay notification step (ST8) may be executed.

Next, the proposal unit 17 extracts a planning process that can eliminate the delay from the re-created production plan and proposes a countermeasure (ST9: countermeasure proposal process). In the "measure proposal" display frame 57 of the plan progress notification screen 50 shown in FIG. 7, the measures proposed by the proposal unit 17 are displayed. In this way, by acquiring the information on the operating status of the floor F (ST2) and recreating the subsequent production plan (ST5), it is possible to create a highly accurate production plan based on the production status.

As described above, the management computer 3 of the present embodiment includes a production plan creation unit 11 for creating a production plan and an acquisition unit 12 for acquiring information on the operating status of the floor F, and creates a production plan. The unit 11 is a production management device that manages the production of the product (mounting board) that recreates the subsequent production plan (creates the recreated production plan) based on the acquired operating status of the floor F. This makes it possible to create a highly accurate production plan based on the production situation.

The above description has been made based on the embodiment of the present invention. It will be understood by those skilled in the art that this embodiment allows various modifications to the types and combinations of products produced by the production equipment on the floor F, and that such modifications are also within the scope of the present invention. By the way. For example, the production of the product managed by the production control device may be the production of electronic equipment on the assembled production line or the production of processed food products on the food processing line.

In the embodiment of the present invention, the acquisition unit has been described as an imaging device, but the acquisition unit may be any device other than the imaging device that can specify the positions of the worker W and the automatic guided vehicle V. For example, the positions of the worker W and the automatic guided vehicle V may be specified by using a beacon, GPS, or the like. When a beacon, GPS, or the like is used, the flow line analysis unit 13 is in motion when the signal transmitted from the worker W or the automatic guided vehicle V is moving, and the production is targeted at the worker W or the automatic guided vehicle V. When the equipment is stopped, it is during work, and when the worker W or automatic guided vehicle V is stopped at other than the target production equipment, it is easy to analyze the flow line and work status as non-working. Can be done.

The production control device and the production plan creation method of the present invention have the effect of being able to create a highly accurate production plan based on the production situation, and are useful in the field of mounting parts on a substrate.
