Description

  The present invention relates to a production management apparatus, a production management method, a production management program, a recording medium on which a production management program is recorded, and a production system for managing production progress in a production line.

  With the shortening of the product life cycle and the diversification of user needs, the manufacturing industry is forced to respond to high-mix low-volume production, short delivery time production, variable-volume production, and the like. In response to such environmental changes, an increasing number of factories are shifting from automated lines where machines automatically process and assemble products to hand-assembled lines where people manually process and assemble.

  The hand-assembled line is a production method in which multi-skilled workers share work flexibly in a small-scale line. The cell production system is a form of hand-assembled line.

  In the hand-assembled line, an operator performs production using a work table and jigs, and there is no need to provide a large-scale automatic production machine, so there is an advantage that equipment can be simplified. Moreover, since various production processes can be realized by changing the contents of work performed by the worker, there is also an advantage that a large variety of products can be produced in a short delivery time.

  In the hand-assembled line, a series of operations necessary for product production is divided into a plurality of processes, and a work place and a work procedure are determined for each process. An operator is assigned to each process, and a product is completed when all the operations from the first process to the last process are executed in order. There are various forms of the number of workers arranged in the entire line and the number of processes handled by one worker.

  Generally, several to thousands of products are produced every day on the hand-assembled line. Each product has a delivery date promised to the customer, and it is necessary to complete the production of all products by the delivery date. For this reason, a production plan in which the production start time and production completion time of each product are determined is established, and production is executed according to this production plan.

  However, when production is actually executed, the work may not proceed according to the production plan due to factors attributable to the operator, factors attributable to the tool, factors attributable to the production object, and the like. Factors attributed to the worker include that the worker is not working for some reason, the worker's proficiency level is low, a work mistake has occurred, and a correction work is performed to recover the work mistake. Or the work is delayed due to the physical illness of the worker. Factors resulting from the tool include failure of the tool and loss of the tool. Factors resulting from the production object include a defect in the production object itself, a missing item, and the like.

  As described above, the production on the hand-assembled line is not necessarily executed according to the production plan, and thus progress management is required. In the progress management, three procedures of delay detection, situation grasp, and countermeasure are repeatedly executed. The delay detection is to detect the occurrence of a delay with respect to the production plan. Situation grasping is how long the detected delay time is in relation to the production plan (understanding the urgency of countermeasures), and in which process the detected delay is occurring (in the areas where countermeasures are required) Grasping). The measure is to take and implement a measure to eliminate the delay. Measures for eliminating the delay include, for example, increasing the number of workers, exchanging jigs and tools, discarding and recreating defective products, and changing the production order.

  In order to ensure that all products are completed by the delivery date and to secure the profits of the factory, it is essential to improve the efficiency of this progress management procedure. If progress management requires a large amount of man-hours, production managers are constantly chased by response to delivery date troubles, not spending time on improvement activities, and are more competitive than competitors' production lines. descend.

  Conventionally, a progress display board has been used to improve the efficiency of progress management. The progress display board presents information on the number of scheduled tasks, the number of completed tasks, the number of delays, etc. in a tabular format for each time period during which the task is performed. Actually, the progress display board is realized by a white board or the like, and each information is manually written by a human.

  In addition, a progress indicator obtained by further evolving the above progress indicator is also used. This progress indicator measures the number of completed production based on the input from the sensor / switch that detects the completion of production, and compares it with the planned value to show how many units the current performance is delayed from the production plan. To display.

  Furthermore, Patent Document 1 discloses an information display device that displays details of production completion works in order to improve the efficiency of progress management. This information display device displays the number of completed productions and the scheduled shipping date for each shipping destination.

Patent Document 2 discloses a lot number display device that displays a work completion status for each number. This lot number display device compares the number of production planned and the number of actually executed for each lot, and displays the presence / absence of delay in the plan.

For this reason, when examining countermeasures, on-site observation, production plan forms / file checks, interviews with workers, etc., information on margin time, delay generation process, and delay factors for work in progress and unstarted work The work of collecting over time is required. In addition, when there is a shortage of information on the cause of delay, a task is required in which a skilled administrator with abundant experience and knowledge guesses the shortage information.

In the example shown in FIG. 1, the production system 1 monitors a production line including n processes (process 1 to process n) for manufacturing a product by an operator's manual work, and the work of each of the above processes, The configuration includes a production management device 2 that displays the progress status and an imaging device 3 that captures the status of work performed in each process in the production line.

  Steps 1 to n are arranged in this order from the upstream to the downstream of the flow of the workpiece (object) as the manufacturing object of the production system 1, and the workpiece is moved from the first step (step 1) to the final step. The product is completed when the operations of all the steps are sequentially performed through (step n).

  The imaging device 3 is installed at least at one place in a region where work is actually performed on the production line, and is configured by, for example, a CCD (charge-coupled device) or a CMOS device. Work conditions in all processes included in the production line are photographed by the imaging device 3. One imaging device 3 may shoot the situation of all the steps, or a plurality of imaging devices 3...

  Furthermore, the production system 1 includes sensors (process detection devices) 4A1 to 4Am for detecting the work of the worker for each process. In addition, when it is not necessary to distinguish the sensors 4A1 to 4Am, they are simply referred to as sensors 4.

  The sensor 4 detects the start and / or end of work in each process, and at least one sensor 4 is installed in each process. For example, the sensor 4 detects the presence / absence of a workpiece, the movement of a jig, the presence / absence of an instruction, the opening / closing of a door, the ON / OFF of a power supply of an electric facility, and the like, and outputs the detection signal to the production management device 2. Specific examples of the sensor 4 include a photoelectric sensor, a proximity sensor, a displacement sensor, a photomicrosensor, an ultrasonic sensor, and a pressure sensor. The sensor 4 may be configured to detect the start and / or end of work in the process by pressing a button or the like when the worker starts and / or finishes the work.

  In the present embodiment, among the sensors 4A1 to 4Am, sensors 4A1 and 4Am installed at the work place of the first process and the process n work place of the final process are attached to each work. A barcode reader (specific device) that reads a barcode indicating ID (object identification information) is used. As described above, the work ID is detected in the first process and the final process, and the detection result is input to the production management apparatus 2, so that the production management apparatus 2 can process which work ID is processed in each process. It becomes possible to grasp whether it is.

  In the above example, the work ID is detected in the first process and the final process. However, it is only necessary to provide an ID detection means for detecting the work ID in at least one process. In the above example, a bar code reader is used to detect the work ID, but input means for receiving an input of the work ID by the operator may be used.

  The production management device 2 and the imaging device 3 and the production management device 2 and the sensor 4 are connected to each other by communication means. Examples of the communication means include wired communication, infrared communication, Bluetooth (registered trademark), and wireless LAN (Local Area Network).

Each process has a work place and a work procedure, and a work table and jigs are installed in each work place. Or the production equipment which an operator operates may be installed.

  As described above, in the hand-assembled production line, a series of operations necessary for product production is divided into a plurality of steps (in this example, steps 1 to 8), and a work place and a work procedure are determined for each step. An operator is assigned to each process, and a product is completed when all the operations from the first process (process 1) to the final process (process 8) are sequentially performed.

  In the present embodiment, all the processes of the production system 1 are manually assembled lines by workers. However, the present invention is applicable to a production system including a process in which assembly and production are automatically performed by a production facility. It is possible to apply

(Configuration of production management device)
The production management apparatus 2 includes a display unit (display device) 11, a production work display control unit (display control unit) 12, a completed work display control unit (display control unit) 13, and an unstarted work display control unit (display control unit). 14, scheduled result comparison unit (scheduled result comparison unit) 15, work result acquisition unit (work result acquisition unit) 16, input unit 17, production plan recording unit 18, work result recording unit 19, time supply unit 20, recording unit 21 The captured image recording unit 22 and the progress information recording unit 23 are provided.

  The work performance acquisition unit 16 receives the detection signals (process detection signals) from the sensors 4... And analyzes the contents of the detection signals, so that each of the work results acquisition unit 16 is based on the current time information supplied from the time supply unit 20. For each work ID, a process of acquiring a work start time (work result time) and a work end time (work result time) in each process is performed. With respect to the process in which the work start or work end is detected by a sensor that does not perform detection until the work ID is detected, not the ID detection means such as a barcode reader, the work result acquisition unit 16 performs upstream processing as viewed from the sensor. In addition, the work ID input by the ID detecting means installed in the latest process is regarded as the work ID of the work that has started or ended the work in the process corresponding to the sensor. Information on the work start time and work end time in each process for each work ID acquired by the work record acquisition unit 16 is recorded in the work record recording unit 19.

  An example of work performance information recorded in the work performance recording unit 19 is shown in FIG. As shown in the figure, the work performance information is a table in which the work start time and the work end time in each of steps 1 to n are recorded for each work ID. This work result information is recorded in order from the work ID with the earliest work start time of the first process (process 1).

  The input unit 17 performs processing for receiving input of production plan information. The production plan information includes information on the scheduled work start time, scheduled work end time, and delivery time for each process for each work ID. The production plan information may be input directly by the production manager using an input means such as a keyboard or a mouse, or may be performed by reading a recording medium on which the production plan information is recorded, or a communication network. It may be performed by acquiring production plan information from the outside via.

  The production plan recording unit 18 records the production plan information received by the input unit 17. FIG. 3 shows an example of production plan information recorded in the production plan recording unit 18. As shown in the figure, the production plan information is a table in which the scheduled work start time, scheduled work end time, and delivery time in each of the processes 1 to n are recorded in a table format for each work ID. . This production plan information is recorded in order from the work ID with the earliest work start time of the first process (process 1).

  The recording unit 21 performs processing for acquiring captured image data captured by the imaging device 3 from the imaging device 3 via a communication unit. The captured image data acquired by the recording unit 21 is recorded in the captured image recording unit 22. The recording unit 21 transmits the captured image data recorded in the captured image recording unit 22 to the work display control unit 12 during production. The captured image data may be moving image data, or may be a plurality of still image data captured at predetermined time intervals. The captured image recording unit 22 has at least a function of temporarily storing captured image data acquired from the imaging device 3 as a buffer, and may store a predetermined amount of past captured image data.

  When the past captured image data is stored, the recording unit 21 may also record information of the captured time with respect to the captured image data. As a result, the work-in-production display control unit, which will be described later, can display the captured image by specifying the time.

  The scheduled performance comparison unit 15 compares the work performance information recorded in the work performance recording unit 19 with the production plan information recorded in the production plan recording unit 18, and schedules in each process for each work ID. A process of calculating a delay time and a margin time with respect to is performed. This process is performed each time a work result is newly acquired by the work result acquisition unit 16 and the work result information recorded in the work result recording unit 19 is updated.

  The delay time in each process of each work ID is calculated as the delay amount of the start time or end time of each process recorded as work performance information with respect to the start time or end time of each process recorded as production plan information. It is obtained by doing. The margin time corresponding to each work ID is calculated for each of a work that has been produced (production completed work), a work that is in production (work in production), and a work that has not yet been produced (unstarted work). This is done by a corresponding calculation method. Details of the calculation of the delay time and the margin time will be described later.

  Information on the delay time and the margin time calculated by the scheduled performance comparison unit 15 is recorded in the progress information recording unit 23 as progress information.

  FIG. 4 shows an example of progress information recorded in the progress information recording unit 23. As shown in the figure, the progress information is obtained by recording the work start time and the delay time with respect to the work end time in each of the steps 1 to n and the margin time in a table format for each work ID. Yes. This progress information is recorded in order from the work ID with the earliest work start time of the first process (process 1).

  The display unit 11 displays production progress information based on display control performed by the production work display control unit 12, the completed work display control unit 13, and the unstarted work display control unit 14. The display unit 11 may be realized by any display device as long as it can display information. Examples of such a display device include a liquid crystal display device and a CRT (Cathode Ray Tube).

  The completed work display control unit 13 obtains the work ID and delay time information of the production completed work recorded in the progress information recording unit 23 from the scheduled performance comparison unit 15 and displays this as progress information of the production completed work. Control to be displayed on the unit 11 is performed. FIG. 5 shows a display example of the progress information of the production completion work. As shown in the figure, the progress information of the production completion work is displayed in a tabular form with a work ID and delay time information corresponding to the work ID. Here, the completed work display control unit 13 recognizes, in the progress information recording unit 23, the work ID in which the information on the delay time of the work end of the final process is recorded as the production completed work. In addition, as progress information of the production completion work, information on a margin time corresponding to each work ID may be displayed.

  The work-in-production display control unit 12 obtains information on the work ID, delay time, and margin time of the work in production recorded in the progress information recording unit 23 from the scheduled performance comparison unit 15, and uses this information for the work in production. Is displayed on the display unit 11 as progress information. Further, the production work display control unit 12 acquires the captured image data recorded in the captured image recording unit 22 from the recording unit 21 and displays the images of the work status in all the processes at that time on the display unit 11. Control. Here, in the production work display control unit 12, in the progress information recording unit 23, information on the delay time of the work start of the first process is recorded, but information on the delay time of the work end of the last process is recorded. Recognize no workpiece ID as a workpiece in production.

  FIG. 6 shows a display example of the progress information and work status image of the workpiece being produced. As shown in the figure, the progress information of the work in production is displayed in the vicinity of the image indicating the work status of each process, the work ID of the work being performed in the corresponding process, and the corresponding delay time. This information is displayed by displaying information on the time and information on the spare time. Here, the display of the progress information regarding the work in which the delay has occurred and / or the work in which the margin time is negative may be highlighted. As this highlighting, for example, the background and / or character display form (color, pattern, font, inversion, etc.) may be different from the normal display form.

  As described above, the progress information of the workpiece being produced is displayed in the vicinity of the image indicating the work status of each process, thereby producing the following effects. First, there is an effect that it becomes easy for the production manager to grasp which process the work in production for which progress information is shown is being processed along with the process video. In addition, when different types of products are produced, even if it is difficult to immediately recognize which type of product work is based on the work ID alone, the process image is displayed. This has the effect of making it easier for the production manager to understand what kind of product is being produced. In addition, when a delay has occurred, if the cause of the delay is of a type that can be recognized by checking the work status, the production manager can confirm the cause of the delay by checking the video of the process. There is an effect that it can be grasped.

  In this example, the progress information of the workpiece in production is displayed in the vicinity of the image indicating the work status of each process, but is not limited thereto, and an image indicating the work status of each process; It only needs to be displayed in a state in which the corresponding relationship with the progress information of the workpiece in production corresponding thereto is shown.

  In the above example, the progress information of the workpiece being produced is displayed together with the work status image. However, the progress information of the workpiece being produced corresponds to the information indicating the process corresponding to the workpiece being produced. It may also be displayed. For example, the name of the process corresponding to the workpiece in production and the progress information of the workpiece in production may be displayed together.

  The unstarted work display control unit 14 acquires the information of the work ID of the unstarted work and the margin time recorded in the progress information recording unit 23 from the scheduled performance comparison unit 15, and uses this as progress information of the unstarted work Control to display on the display unit 11 is performed. Here, the unstarted work display control unit 14 recognizes, in the progress information recording unit 23, a work ID in which information on the delay time for starting the work in the first process is not recorded as an unstarted work.

  FIG. 7 shows a display example of progress information of unstarted work. As shown in the figure, the progress information of the unstarted work is displayed in a tabular form with a work ID and information on a spare time corresponding to the work ID. Here, the display of the progress information regarding the work having a negative margin time may be highlighted as in the above-described work in production.

  FIG. 10 shows an example of a screen displayed on the display unit 11 by the work-in-production display control unit 12, the completed workpiece display control unit 13, and the unstarted workpiece display control unit 14. As shown in the figure, a table showing the progress information of unstarted work is displayed in the left area of the screen. In the center area of the screen, a work status image and a table showing the progress information of the work in production that is being performed in the corresponding process are displayed in the vicinity of the image indicating the work status of each process. . In addition, a table showing the progress information of the production completion work is displayed in the area on the right side of the screen.

(Calculation of spare time)
Next, calculation of the margin time corresponding to each work ID by the scheduled performance comparison unit 15 will be described. First, as a premise, the current delay time of each work in production is defined as follows.

  (Current delay time) = (Delay time of start time or end time in the most downstream process among delay times recorded as progress information)

  There are several possible variations for how to calculate the margin time. Hereinafter, five types of margin time calculation methods will be described.

(First margin calculation method)
The margin time for the production completion work is calculated as follows.

(Lead time for production completion work) = (Delivery time of own work)-(Work end time of final process)
The margin time for workpieces in production is calculated as follows.

  (Lead time for work in production) = (Delivery time of own work)-(Scheduled work end time of own work)-(Maximum current delay time of work (including own work) being produced in the process downstream from own work) value)

  The margin time for unstarted work is calculated as follows.

  (Lead time for unfinished work) = (Delivery time of own work)-(Scheduled work end time of own work)-(Maximum current delay time of work in production)

(Second margin calculation method)
This calculation method is a calculation method that does not consider the current performance in the margin time of workpieces in production and unstarted workpieces.

  The margin time for the production completion work is calculated as follows.

(Lead time for production completion work) = (Delivery time of own work)-(Work end time of final process)
The margin time for workpieces in production is calculated as follows.

(Lead time for work in production) = (Delivery time for own work)-(Scheduled work end time for own work)

  By using any of the calculation methods as described above, it is possible to calculate a margin time corresponding to each work ID.

(Process flow)
Next, the flow of processing in the production management apparatus 2 will be described with reference to the flowchart shown in FIG. First, in step 1 (hereinafter referred to as S1), the input unit 17 performs a process of receiving input of production plan information. The input production plan information is recorded in the production plan recording unit 18.

  Next, the scheduled performance comparison unit 15 performs a margin time calculation process for unstarted work among the work IDs included in the production plan information (S2). Immediately after the production management device 2 is activated, all work IDs are unstarted work, so a margin time is calculated for all work IDs. The calculated margin time information is recorded in the progress information recording unit 23.

  Next, the completed work display control unit 13 acquires information on the work ID and delay time of the production completed work recorded in the progress information recording unit 23, and displays this on the display unit 11 as progress information of the production completed work. Control is performed (S3). Since the production completed work does not exist immediately after the production management device 2 is activated, the progress information regarding the completed work displayed here is empty.

  Next, the work-in-production display control unit 12 obtains information on the work ID, delay time, and margin time of the work in production recorded in the progress information recording unit 23, and uses this as progress information of the work in production. Control to display on the display unit 11 is performed. Further, the production work display control unit 12 acquires the captured image data recorded in the captured image recording unit 22 and performs control to display the images of the work status in all the processes at that time on the display unit 11. (S4). It should be noted that immediately after the production management device 2 is activated, there is no work-in-progress, so the progress information regarding the work-in-production displayed here is empty, and only an image of the work situation is displayed.

  Next, the unstarted work display control unit 14 acquires the information of the work ID of the unstarted work and the margin time recorded in the progress information recording unit 23, and uses this information on the display unit 11 as the progress information of the unstarted work. Display control is performed (S5). Note that the processes of S3 to S5 are not limited to being performed in this order, and may be performed simultaneously or in other orders.

  Thereafter, in S6, the work record acquisition unit 16 receives a detection signal from any of the sensors 4 and analyzes the content of the detection signal, so that the work is started in a certain process, or in a certain process. It is determined whether the work is finished. If the start or end of the work is not detected, this determination process is repeated until the start or end of the work is detected.

  When the start or end of work is detected, the work record acquisition unit 16 acquires the current time from the time supply unit 20 and records the work record as the work start time or work end time for the corresponding process of the corresponding work ID. It records in the part 19 (S7).

  When the work record information recorded in the work record recording unit 19 is updated, the scheduled record comparison unit 15 calculates a delay time and a margin time for each process for the work ID with the updated work record (S8). The progress information recorded in the progress information recording unit 23 is updated based on the calculated delay time and margin time information.

  Thereafter, the work-in-production display control unit 12 updates the display of progress information related to the work in production based on the updated progress information (S9). Further, the unstarted work display control unit 14 updates the display of the progress information regarding the unstarted work based on the updated progress information (S10). In addition, when the completed work display control unit 13 detects the start or end of the work at the end of the work in the final process (YES in S11), the progress on the completed work is based on the updated progress information. The display of information is updated (S12). Note that the processes of S9 to S12 are not limited to being performed in this order, and may be performed simultaneously or in other orders. Thereafter, returning to the process from S6, the processes from S6 to S12 are repeated until an instruction to end the process in the production management apparatus 2 is given.

(Other display examples of work status images)
In the above configuration, the imaging device 3 is provided in a region where work is actually performed on the production line, and a captured image captured by the imaging device 3 is displayed on the display unit 11 as a work status image. ing. On the other hand, a schematic diagram of a production line may be displayed on the display unit 11 without providing the imaging device 3.

  FIG. 11 shows a schematic configuration of the production system 1 that realizes that a schematic diagram of the production line is displayed on the display unit 11. As shown in the figure, the imaging system 3 is not provided in the production system 1. In addition, the production management device 2 has a configuration including a schematic diagram generation unit 31 and a schematic image recording unit 32 instead of including the recording unit 21 and the captured image recording unit 22.

  The schematic image recording unit 32 records schematic image data schematically showing each process of the production line. In the schematic diagram shown by the schematic image data, at least a figure showing each process of the production line is drawn.

  The schematic diagram generation unit 31 indicates a figure indicating a workpiece and / or an operator at or near the part of the figure corresponding to the process in operation with respect to the schematic image data recorded in the schematic image recording unit 32. A process of drawing a figure and generating a schematic diagram is performed. An example of this schematic diagram is shown in FIG. The schematic diagram generation unit 31 acquires work result information from the work result recording unit 19, extracts a process in which the work start time is recorded and no work end time is recorded, and the extracted process is Recognize as a process in progress.

  The progress information of the work in production is displayed near the image corresponding to each process in the schematic diagram, the work ID of the work being performed in the corresponding process, the delay time information corresponding to it, and the margin time. This is done by displaying information. Here, similarly to the above, the display of the progress information regarding the work in which the delay occurs and / or the work in which the margin time is negative may be highlighted.

  By displaying the schematic diagram as described above, it is easier for the production manager to grasp which process the work in production for which progress information is shown is being processed, and it is necessary to provide an imaging device on the production line The cost can be reduced by eliminating Also, for example, if the figure showing the workpiece displayed in the schematic diagram is changed according to the type of workpiece, when different types of products are produced, the workpiece ID of which type of product is used. Even when it is difficult to immediately recognize whether or not there is, it is possible for the production manager to easily understand what kind of product is being produced.

  In this example, the progress information of the workpiece being produced is displayed in the vicinity of the image corresponding to each process. However, the present invention is not limited to this, and the image corresponding to each process and the production corresponding thereto are displayed. It only needs to be displayed in a state where the correspondence with the progress information of the medium work is shown.

  In the above example, the schematic diagram generation unit 31 draws an image of a work or an operator for the process being worked on. The schematic image data recorded in the unit 32 may be displayed as it is.

(Specify playback time of work status image)
In the above configuration, as shown in FIG. 10 and the like, a real-time captured image at that time is displayed as a work situation image. On the other hand, in order to be able to display the work situation image retroactively, the reproduction time of the work situation image may be designated.

  FIG. 13 shows a schematic configuration of the production system 1 that realizes the reproduction time designation of the work status image. As shown in the figure, the production management device 2 further includes a work result filter unit (work result changing unit) 41 and a reproduction time designation unit (reproduction time designation unit) 42 as compared with the configuration shown in FIG. It has a configuration. The other configuration is the same as the configuration shown in FIG.

  The reproduction time designation unit 42 performs a process of receiving a reproduction control input for changing the reproduction time of the work situation image from the user. FIG. 14 shows an example of a display screen provided with a user interface for realizing reproduction control input reception by the reproduction time designation unit 42. As shown in the drawing, a slider B1, a rewind button B2, a playback button B3, a stop button B4, a fast forward button B5, a live button B6, and a time input area B7 are provided in the work status image playback control area. .

  The live button B <b> 6 is a button for receiving an instruction input for reproducing the work situation image at the current time supplied from the time supply unit 20. The time input area B7 is a display input area for displaying the time of the displayed work situation image and for reproducing the work situation image from that time by directly inputting the time in this area.

  The reproduction button B3 is a button for receiving an instruction input for reproducing the work situation image from the time displayed on the time input unit B7. The stop button B4 is a button for receiving an instruction input for stopping the reproduction of the work situation image. When the stop button B4 is pressed, the image at the time displayed on the time input unit B7 at that time may be displayed as a still image.

  The fast-forward button B5 is a button for receiving an instruction input for fast-forwarding the reproduction of the work situation image. The rewind button B2 is a button for receiving an instruction input for rewinding the reproduction of the work situation image. The slider B1 displays the reproduction time of the work situation image according to the position of the slider B1, and realizes reproduction from the moved time by moving the slider B1 by the user.

  Returning to FIG. 13, the work performance filter unit 41 acquires the time designated by the reproduction time designation unit 42, and the work after the designated time among the work performance information recorded in the work performance recording unit 19. A process of sending the data from which the record is deleted to the scheduled record comparison unit 15 is performed. As a result, the progress information of the workpiece being produced reflects the progress status at the reproduction time of the work situation image, and the progress information of the workpiece being produced is displayed in synchronization with the reproduction of the work situation image.

  FIG. 15 is a flowchart showing the flow of processing in the production management apparatus 2 when the reproduction time is designated. In the figure, the processing of S21 to S27 and the processing of S29 to S33 are the same as the processing of S1 to S7 and the processing of S8 to S12 in the flowchart shown in FIG. Is omitted.

In the process flow shown in FIG. 15, when the work record information recorded in the work record recording unit 19 is updated in S <b> 27, the reproduction control input is accepted by the reproduction time designating unit 42, and the work record filter unit 41 performs the process control. Then, a filtering process is performed in which data obtained by deleting work results after the designated time is sent to the scheduled result comparison unit 15 (S28) . Thereafter, the scheduled performance comparison unit 15 calculates a delay time and a margin time for each process based on the work performance on which the filtering process has been performed. The progress information recorded in the progress information recording unit 23 is updated based on the calculated delay time and margin time information.

  According to the above configuration, since it is possible to display the work status image by specifying the reproduction time, the occurrence status of the delay can be confirmed by displaying the work status image retroactively. Can do. Therefore, it becomes possible to grasp the cause of the delay and examine the countermeasure more appropriately and efficiently.

(Specify playback time based on delay start time)
In the above configuration, it is possible to arbitrarily specify the playback time. However, it is possible to record the time when the delay started and record the playback time from the list of the delay start times. It may be.

  FIG. 16 shows a schematic configuration of the production system 1 that realizes the reproduction time designation based on the delay start time. As shown in the figure, the production management device 2 has a configuration further including a delay start time acquisition unit 43 as compared with the configuration shown in FIG. The other configuration is the same as the configuration shown in FIG. 13 described above, and a description thereof will be omitted.

  The delay start time acquisition unit 43 refers to the progress information recorded in the progress information recording unit 23 to perform processing for extracting the time at which the delay starts. Specifically, the delay start time acquisition unit 43 extracts, from the progress information, the time at which the delay time has changed from a zero state to a positive value for all workpieces in production. FIG. 17 shows an example of a list of delay start times extracted by the delay start time acquisition unit 43. Note that a delay start time recording unit that records a list of delay start times extracted by the delay start time acquisition unit 43 may be further provided.

  The reproduction time designation unit 42 receives a list of delay start times from the delay start time acquisition unit 43 and causes the display unit 11 to display the list of delay start times as means for designating the reproduction time. FIG. 18 shows an example of a display screen provided with a user interface that realizes that the playback time is specified by the list of delay start times. As shown in the figure, a list of delay start times is displayed, and a delay start time designation area B8 is provided in which the delay start times included in the list are designated as reproduction start times.

  According to the above configuration, the user can select the playback start time from the list of delay start times. Here, it is expected that the time at which the delay starts is likely to be the time at which the situation causing the delay occurs. Therefore, by starting the reproduction of the work situation image from the delay start time, the user can grasp the cause of the delay more quickly.

(Work search)
In the above configuration, a search function using a work ID may be further provided. FIG. 19 shows a schematic configuration of the production system 1 that realizes search by work ID. As shown in the figure, the production management device 2 has a configuration further including a workpiece specifying unit 51 and a workpiece search unit (object search unit) 52 as compared with the configuration shown in FIG. The other configuration is the same as the configuration shown in FIG.

  The work specifying unit 51 performs a process of receiving an input of a work ID of a work for which progress information is to be displayed. FIG. 20 shows an example of a display screen provided with a user interface that realizes work ID input reception by the work specifying unit 51. As shown in the figure, a work designation area B9 is provided as an input area for a work ID to be searched.

  The work search unit 52 performs a process of searching for progress information related to the work ID received by the work specifying unit 51 from the progress information recorded in the progress information recording unit 23. Then, the work search unit 52 displays the completed work display control unit 13 if the work ID to be searched has been completed, displays the in-production work display control unit 12 if production is in progress, and displays the unstarted work display if it has not started. The control unit 14 is instructed to highlight the work ID. As this highlighting, for example, the background and / or character display form (color, pattern, font, inversion, etc.) may be different from the normal display form.

  FIG. 21 is a flowchart showing the flow of processing when a workpiece search is performed. First, in S41, the work specifying unit 51 receives an input from a user of a work ID of a work for which progress information is to be displayed. In step S <b> 42, the work search unit 52 performs a process of searching for progress information related to the search target work ID received by the work specification unit 51 from the progress information recorded in the progress information recording unit 23. When the progress information regarding the search target work ID is detected, the work search unit 52 determines whether the work of the corresponding work ID is completed, in production, or not yet started (S43).

  When the production of the work of the corresponding work ID is completed, the work search unit 52 transmits the corresponding work ID to the completed work display control unit 13 (S44). Upon receiving the corresponding work ID from the work search unit 52, the completed work display control unit 13 highlights the progress information related to the corresponding work ID among the work IDs displayed on the display unit 11 as the progress information of the production completed work. The display unit 11 is controlled as described above (S45).

  When the work with the corresponding work ID is in production, the work search unit 52 transmits the corresponding work ID to the work-in-production display control unit 12 (S46). When the work display control unit 12 in production receives the corresponding work ID from the work search unit 52, the work information displayed on the display unit 11 as the progress information of the work being produced is highlighted in the progress information related to the work ID. The display unit 11 is controlled to do so (S47).

  If the work with the corresponding work ID has not been started, the work search unit 52 transmits the corresponding work ID to the unstarted work display control unit 14 (S48). Upon receiving the corresponding work ID from the work search unit 52, the unstarted work display control unit 14 highlights the progress information related to the corresponding work ID among the work IDs displayed on the display unit 11 as the progress information of the unstarted work. The display unit 11 is controlled to do so (S49).

  According to the above configuration, the user can easily recognize under what circumstances the work related to the work ID is currently produced by inputting the work ID.

  In the above example, the work ID search function is added to the structure shown in FIG. 1, but the search function is added to any of the structures shown in FIGS. It is also possible to do.

(Display of worker name)
In the above configuration, the name of the worker in the corresponding process may be displayed in the display of the progress information of the workpiece in production. FIG. 22 shows a schematic configuration of the production system 1 that realizes the display of the worker name. As shown in the figure, the production management device 2 is configured to include an operator recording unit 61 and an operator input unit 62 as compared to the configuration illustrated in FIG. The other configuration is the same as the configuration shown in FIG.

  The worker input unit 62 performs a process of receiving an input of the worker name in each process. For example, the worker input unit 62 may display a worker input display screen on the display unit 11 and input the worker name by an input unit such as a keyboard. Further, for example, by receiving data such as a shift table in the production line, the name of the operator in each process may be input.

  The worker recording unit 61 records a list of worker names (worker name list) input by the worker input unit 62 in each process. FIG. 23 shows an example of a list of worker names recorded in the worker recording unit 61. In the example shown in the figure, the worker name corresponding to each process is recorded in a table format. FIG. 24 shows another example of a list of worker names recorded in the worker recording unit 61. In the example shown in the figure, for each process, the corresponding worker name is recorded in a table format according to the time zone.

  The production work display control unit 12 also displays the worker name for each process by referring to the worker name list recorded in the worker recording unit 61 when displaying the progress information of the production work. Thus, the display unit 11 is controlled. FIG. 25 shows a display example in which the worker name of each process is also displayed in the progress information of the workpiece in production. As shown in FIG. 24, when the worker name corresponding to the time zone is written in the list of worker names, the in-production workpiece display control unit 12 is currently supplied from the time supply unit 20. Based on the time, the worker of each process at that time is recognized and displayed.

  According to the above configuration, the user can recognize the worker in each process with respect to the workpiece being produced. Therefore, when a delay occurs, whether or not the cause of the delay is in the worker. It becomes possible to use it for the judgment.

  In the above example, an operator name display function is added to the configuration shown in FIG. 1, but the operator name is added to any of the configurations in FIGS. 11, 13, 16, and 19. A configuration in which a display function is added is also possible.

(Display of parts inventory)
In the configuration described above, the number of parts used in each process may be displayed in the progress information display of the workpiece being produced. FIG. 26 shows a schematic configuration of the production system 1 that realizes display of the number of parts in stock. As shown in the figure, the production system 1 is provided with parts inventory counters 71. The other configuration is the same as the configuration shown in FIG.

  The parts inventory counter 71 is provided in each process, counts the number of parts necessary for the work in the process, and transmits the count value to the work display control unit 12 during production. The parts inventory counter 71 is constituted by, for example, a switch or a sensor. When the parts inventory counter 71 is composed of switches, the use of parts can be counted by, for example, pressing the switch every time a worker uses one part. In addition, when the parts inventory counter 71 is constituted by a sensor, the number of parts in stock can be counted by providing a sensor for detecting the presence or absence of a part in the part storage area.

  The work-in-production display control unit 12 displays the part inventory quantity for each process by receiving the part inventory count value from the parts inventory counter 71 when displaying the progress information of the work in production. The display unit 11 is controlled. FIG. 27 shows a display example in which the number of parts inventory for each process is also displayed in the progress information of the workpiece in production. Here, the in-production work display control unit 12 may control the display unit 11 to highlight the number of parts in stock when detecting that the number of parts in stock falls below a predetermined threshold. Examples of the highlighting include making the background and / or character display form (color, pattern, font, inversion, etc.) different from the normal display form.

  According to the above configuration, the user can check the number of parts in each process, and thus it is possible to prevent a delay in work due to the lack of parts in stock. Further, when the cause of delay is due to the absence of parts in stock, this can be quickly confirmed.

  In the above example, the function of displaying the number of parts inventory is added to the structure shown in FIG. 1, but the parts inventory is added to any of the structures shown in FIGS. 11, 13, 16, 19, and 22. It is also possible to adopt a configuration in which a number display function is added.
