  Hereinafter, a method of using the creating apparatus A having the above configuration will be described. In this embodiment, the operation | work which attaches a wiper apparatus to the vehicle body of a motor vehicle is illustrated. In this example, the work of attaching the wiper device to the vehicle body mainly includes three types of element work such as “take out the wiper device from the box”, “move (walk) to the car body”, and “attach the wiper device to the car body”. Shall be.

  In order to create the work content table 19 relating to the work of attaching the wiper device, first, the work of a skilled worker who can perform the work to be measured is imaged by the imaging camera 6. In this case, when the imaging camera 6 is pointed at the operator and the imaging icon 10 is operated, imaging is started, and the captured work data is stored (recorded) in the storage unit 3.

  Next, when the reproduction icon 11 is operated, the captured work moving image is reproduced on the moving image display unit 8. By reproducing the work video, it is possible to confirm whether or not the recorded work video is a desired one. Note that the indicator 20 of the progress bar 9 moves from the start position at the left end of the progress bar 9 toward the end position at the right end in accordance with the reproduction of the work video.

  When it is confirmed that the work moving image is desirable, the operation shifts to an operation for dividing a series of work in the work moving image into element work. This starts by operating the playback icon 11 after operating the lap mode selection icon 16. By this operation, the work moving image is reproduced once again in the moving image display unit 8.

  In this state, the lap measurement icon 12 is operated at the start and end timing of the element work. Specifically, while the work moving image is being reproduced, the lap measurement icon 12 is operated in anticipation of the start timing of the work in which the wiper device is taken out of the box. Then, as shown in FIG. 4A, in accordance with this operation, a delimiter line (hereinafter referred to as “first delimiter line”) L1 for dividing the element work so as to intersect (orthogonally) the progress bar 9 is Is displayed. Specifically, when the lap measurement icon 12 is operated, if the indicator 20 moving on the progress bar 9 is at the position indicated by the dotted line, the first separation line L1 is displayed at this position.

  Even if the lap measurement icon 12 is operated, the reproduced work video is played back without stopping, and the indicator 20 moves on the progress bar 9 in conjunction with the progress of the work video. . Thereafter, the lap measurement icon 12 is operated at the timing when the wiper device is completely removed from the box.

  At this time, the indicator 20 on the progress bar 9 has moved to the position indicated by the alternate long and short dash line in FIG. 4A, and the lap measurement icon 12 is operated, so that a separation line (hereinafter “ L2 ”(referred to as“ second separator line ”) is displayed. In this way, the working time (lap time) of the element work “take out the wiper device from the box” is divided on the progress bar 9 by the first dividing line L1 and the second dividing line L2.

  The work to be measured in the present embodiment is that the worker moves to the body of the automobile immediately after the wiper device is taken out of the box. Accordingly, in FIG. 4A, the second separation line L2 indicating the completion of the operation of taking out the wiper device from the box also indicates the start of movement to the vehicle body as the next element operation. In this way, the element work of taking out the wiper device from the box and the element work of moving to the vehicle body are separated on the progress bar 9 by the second separation line L2.

  When the work video is further reproduced, the movement of the worker to the vehicle body is completed. At this time, the indicator 20 on the progress bar 9 has moved to a position indicated by a two-dot chain line in FIG. When the lap measurement icon 12 is operated at this timing, a separation line (hereinafter referred to as “third separation line”) L3 is displayed at the position of the indicator 20. Thereby, the work time of the element work of moving to the vehicle body (walking) is divided on the progress bar 9 by the second dividing line L2 and the third dividing line L3.

  In the present embodiment, when the movement of the worker to the vehicle body is completed, the attachment of the wiper device to the vehicle body is started immediately. Therefore, the third delimiter line L3 indicating the time when the movement to the vehicle body is completed also indicates the time when the attaching operation of the wiper device to the vehicle body is started. That is, the element work of moving to the vehicle body and the element work of attaching the wiper device to the vehicle body are separated on the progress bar 9 by the third dividing line L3.

  Further, the reproduction of the work video advances, and the work for attaching the wiper device to the vehicle body is completed. At this time, the indicator 20 on the progress bar 9 has moved to the position indicated by the solid line in FIG. When the lap measurement icon 12 is operated at this timing, a separation line (hereinafter referred to as “fourth separation line”) L4 is displayed at the position of the indicator 20. Thereby, the working time of the element work of attaching the wiper device to the vehicle body is divided on the progress bar 9 by the third dividing line L3 and the fourth dividing line L4.

  When all the work videos are reproduced, the indicator 20 of the progress bar 9 reaches the right end of the progress bar 9 (position indicating the end of the work video), and then the left end of the progress bar 9 that is the start position. Automatically transition to.

  Thus, the division of the element work is completed. As described above, by operating the lap measurement icon 12 while reproducing and displaying the work moving image on the moving image display unit 8, the start and end times of the element work included in the reproduced work movie are indicated by the dividing lines L1. It can be specified by ~ L4. Although this specification is mainly performed by operating the lap measurement icon 12, the playback speed adjustment icon 18 may be used in combination in order to set the separation lines L1 to L4 more accurately. By operating the playback speed adjustment icon 18, for example, the playback speed of the work video can be reduced and displayed (slow playback), and it is possible to easily identify when the element work is disclosed and when it is finished. .

  If an appropriate operation using the lap measurement icon 12 cannot be performed, for example, when the timing of the touch operation on the lap measurement icon 12 is delayed when specifying the end point of the element work, the lap measurement is performed. By operating the cancel icon 15, it is possible to delete the incorrectly displayed separator line.

  Next, the working time in each element work is measured. This work time is measured in the order of the element work reproduced in the work video, that is, “moving the wiper device from the box”, “moving to the vehicle body”, and “attaching the wiper device to the vehicle body” in this order. Times T1 to T3 (see FIG. 4B) are measured.

  For this reason, when the reproduction icon 11 is operated, the indicator 20 moves on the progress bar 9 from the start position to the right. When the first dividing line L1 is reached in FIG. The work time T1 of the work of taking out the wiper device from the box, which is the element work, is automatically measured.

  When the indicator 20 moves from the position of the first dividing line L1 (indicator 20 is indicated by a two-dot chain line) to the position of the second dividing line L2 (indicator 20 is indicated by a solid line), the measurement of the time T1 during this time is completed. The work video being played is automatically paused. In addition, a pop-up window (not shown) is displayed on the display unit 4, and in this pop-up window, an input screen capable of inputting a work time as a measurement result and a name of the element work, a work A selection screen on which one of “net”, “accompanying”, and “walking”, which are time segments of time, can be selected is displayed.

  The user confirms the measured work time (lap time) and selects a time segment suitable for the work. In this case, the time division of the element work of taking out the wiper device from the box corresponds to “accompanying”. In addition, the user inputs the name of the element work (work content) on the input screen. At this time, when the user touches the input screen, a software keyboard is displayed on the display unit 4. The user uses the software keyboard to input the name of this element work as “take out wiper from box”. Then, as shown in FIG. 3, in the item “1” field of the work content table 19 displayed on the display unit 4, “Remove the wiper from the box” is displayed as the work name, and the work time is further divided. The measurement result of the working time is displayed in “Attachment”. In this embodiment, the case where it takes 1.3 seconds to remove the wiper device from the box is illustrated.

  When the input to the work content table 19 is completed as described above, the temporarily stopped work video is resumed, and the time T2 required to move to the vehicle body is measured. Specifically, the indicator 20 moves on the progress bar 9 from the second dividing line L2 to the third dividing line L3, and the time T2 during this time is automatically measured. The time T2 is measured in the same manner as the time T1 described above, and thereafter, the display unit 4 has a measurement result of the time T2, an input screen for a work name (work content), and a selection screen for selecting a time division. Is displayed.

  Subsequently, the software keyboard is displayed, and the name of the element work is input. When a time segment is further selected, the input and selection contents are reflected in the work contents table 19. In the present embodiment, as shown in FIG. 3, in the column (row) of the item “2” of the work content table 19, “move to the vehicle body” is displayed as the work name, and “walk” in the time section 1.7 seconds are displayed as the measurement result of time T2.

  Next, the work time T3 of the element work of attaching the wiper device to the vehicle body is measured. Specifically, the time T3 until the indicator 20 moves from the third dividing line L3 to the fourth dividing line L4 on the progress bar 9 is automatically measured. Similarly to the times T1 and T2 described above, the measurement result of the work time, the work name input screen, the time segment selection screen, and the software keyboard are also displayed on the display unit 4 for the time T3. As a result of the input of the work name and the selection of the time division, as shown in FIG. 3, “attach a wiper to the vehicle body” is displayed as the work name in the item “3” column (row) of the work content table 19, and the time In the “net” section, 4.0 seconds is displayed as the measurement result of the work time T3.

  In addition, when moving the indicator 20 on the progress bar 9 as described above, the indicator 20 is moved to each of the separation lines L1 to L4 by operating the first cue icon 13 and the second cue icon 14. It can be moved (cueed) to the corresponding position. For example, when the indicator 20 is located between the first dividing line L1 and the second dividing line L2, when the first cueing icon 13 is operated, the indicator 20 immediately moves to the position of the second dividing line L2. When the second cueing icon 14 is operated, the indicator 20 immediately moves to the first separation line L1. As described above, by the cueing operation using the first cue icon 13 and the second cue icon 14, it is possible to more easily measure the work times T1 to T3 in each element work.

  As described above, when the work content table 19 is edited, the work procedure manual including the Gantt chart and other various procedures or procedures reflecting the standardized work process is created by the work procedure manual creation software. Will be. The creation of the work procedure manual may be performed by the creating apparatus A or the server S.

  The symbols T1 to T3 indicating the work time of each element work shown in FIG. 4B are conceptual ones used for convenience to explain the measurement method, and are displayed on the actual display unit 4. It is not something.

  When the lap clear icon 17 on the display unit 4 is operated when the measurement of the work times T1 to T3 as described above is completed, the lap mode is canceled and the separation lines L1 to L4 displayed on the progress bar 9 are displayed. Is erased.
