The vertical axis corresponds to a numerical value based on the number of products. In this case, an example of “designation of points to which the administrator 60 pays attention” is a range 811 for products and processes in the histogram 810 where the difference between ST and actual work time is relatively large. When the range 811 is designated, the attention image 820 may be acquired and displayed using the time and / or position belonging to the range 811 as a key. The attention image 820 may be displayed in a pop-up on the management support screen 800 as in FIG.

The work support described above can be applied to picking support.

FIG. 9 is a diagram showing an example of the picking support screen.

The data store 131 may store a data set representing picking details including details of picking for each item ID as one of the work procedure data sets 312. The work support unit 161 includes an instruction No. related to the product regarding picking performed for the product to be put into the line 150. Is received, the instruction No. Is selected from the procedure store 131, and the instruction number received for the product is identified. And the instruction No. A picking support screen 900, which is a screen showing the picking details associated with, and a UI group that accepts the start and end of picking, may be displayed.

By looking at the picking details and picking, the possibility of eliminating so-called human errors can be increased. This may also be applied to a process called product inspection.

FIG. 10 is a diagram illustrating an example of a work support process performed when a start or end input is received. In FIG. 10, one product and one process are taken as an example (in the description of FIG. 10, “current product” and “target process”).

When the start or end is input for the target process of the current product and the start time or end time is input (registered) (S1001), the work support unit 161 inputs the start time for the target process of the current product, Further, it is determined whether or not there is an input of the end time of the previous product (for example, the product corresponding to the instruction number smaller than the instruction number of the current product) for the target process (S1002).

When the determination result of S1002 is true (S1002: YES), the work support unit 161 sets the start time of the current product as the end time of the previous product for the target process, and the work result data set corresponding to the previous product. It registers in 511 (S1003).

When the determination result of S1002 is false (S1002: NO), the work support unit 161 inputs the end time for the target process of the current product, and there is no input of the start time of the current product for the target process. Whether or not (S1004).

When the determination result of S1004 is true (S1004: YES), the work support unit 161 sets the previous product end time as the start time of the current product for the target process, and the work performance data set corresponding to the current product. It registers in 511 (S1005).

After S1003, after S1005, or when the determination result in S1004 is false (S1004: NO), the work support unit 161 corresponds the start time or end time of the current product for the target process to the current product. Register in the work record data set 511.

According to the process illustrated in FIG. 10, even if the worker 50 forgets to input start or end, an appropriate start time or end time can be registered in the work store 132, thereby maintaining accurate manufacturing management. Can contribute.

FIG. 11 shows the instruction number. It is a figure which shows an example of the work assistance process for reduction of the reading burden of. In FIG. 11, one product is taken as an example (“target product” in the description of FIG. 11).

The work support unit 161 sets the instruction No. received for the first process 1 for the target product input to the line 150. In the case of accepting the instruction No., the remaining instruction steps for the object are indicated in the instruction No. The work support screen (the screen including the instruction number) showing the work details related to the operation number 102 is displayed on the work terminal 102 of each remaining process. Display without receiving.

According to the processing illustrated in FIG. Is read in the first step 1, the instruction No. is read for any remaining steps. Reading of can be omitted. This is indicated by the instruction number. Even if a human error of forgetting the reading operation occurs, it can contribute to maintaining accurate manufacturing control. In addition, the instruction No. The reading of (barcode) (that the work support unit 161 has received an instruction No. for the process 1) may correspond to the input of the start of the process 1. The input (start time registration) of the start of the process m (m is a natural number of 2 or more) after the process 1 is, for example, one of the following, that is, triggered by a simple operation for the worker 50-m. It's okay.
Press a predetermined touch key (start UI 403) on the work support screen 400 (see FIG. 4).
-The worker 50-m steps on the foot pedal when starting the next product in the process m.
In the process m, the worker 50-m says a predetermined word such as “next product”. That the predetermined word is recognized by speech corresponds to the input of the start of the process m.
Regarding the process m, the specific operation of the worker 50-m, the movement on the specific line 150, and the like are identified in the image recognition, and the recognition of the image corresponds to the input of the start of the process m.

As mentioned above, although one embodiment was described, this is an illustration for explaining the present invention, and the scope of the present invention is not limited to this embodiment. The present invention can be implemented in various other forms.

For example, from the management support screen 600 illustrated in FIG. 6 (a screen displaying the result of comparison between ST and actual work time for each process for each product), the product and process in which work time longer than ST occurs. In addition, the manager 60 can also identify products and processes that have been completed in an operation time shorter than ST. If an operation time shorter than ST occurs constantly for a certain process x, there is a need to improve other processes based on the work contents (for example, work procedure) of the worker 50-x of the process x. It is considered that the administrator 60 has. In this case, for example, the administrator 60 designates the process x via the management support screen 600 (for example, designates a display object (for example, a work time display object) related to the process x for a certain product). In response to the designation, the management support unit 162 acquires details regarding the process x from at least one of the point store 131 and the work store 132, and displays a screen showing the details on the management terminal 105. “Details regarding step x” are, for example, at least one of the following:
-Work details of process x,
Details of the worker 50 in charge of the process x (for example, for each item ID of the worker 50 to which the worker number is assigned to the work store 132 for each worker number (an example of a worker ID)) A data set indicating work contents is stored, and the process No., worker No., and item ID are associated with each other, and the work of the worker 50 from the work store 132 using the process No. and the item ID as a key. Content may be obtained),
It's okay. Note that acquiring and displaying details of designated points instead of the target image may be applied to work times longer than ST.
