The worker performs a product assembling operation with reference to the operation diagram screen displayed in FIG.

That is, on the work diagram screen, work instructions and instructions for inspection items are displayed together with input parts and tools to be used. That is, the display units 1 of the terminals 14-1 to 14-n
At 42, a work instruction and an instruction of a tool to be used (for example, an electric driver) are displayed in real time.

As described above, the parts required for the work are placed inside the partitioned boxes 182, and the boxes 182 accommodating the parts to be put in have indicators 184 lit. If the work standard data includes voice data, guidance is also provided by voice (see step 2 in FIG. 6).

A light-emitting portion 186 and a light-receiving portion 188 of the photoelectric sensor are provided at predetermined positions of each box 182, so that it is monitored whether or not the worker has gone to pick up the specified part. (See step 3 in FIG. 6). The data indicating the monitoring result is sent to the server 12 via the terminals 14-1 to 14-n and recorded (step 4 in FIG. 6).

Also, for example, when tightening a screw,
If an operator tries to take the wrong screw, the photoelectric sensor detects the wrong hand and the mistake is displayed on the display unit 142 of the terminals 14-1 to 14-n, and the work diagram screen advances from the display of the work. Disappears.

At this time, if the work standard data includes data relating to voice, the voice also calls for attention.

Further, when it is necessary to inspect the contents of the operation, for example, measuring the set value of the tightening force, in the operation, the display unit 142 displays the necessary information from among the inspection devices constituting the inspection device group 20. Inspection equipment is displayed.

Therefore, the operator only needs to perform the inspection using the inspection equipment displayed on the display unit 142 in the inspection equipment group 20, and the data indicating the inspection result of the judgment and measurement by the inspection equipment group 20 is , Are displayed on a predetermined display unit 142 such as the display unit 20, and the terminals 14-1 to 14-n
Is transmitted to the server 12 and recorded (step 4 in FIG. 6).

Data (processes) such as items related to work contents, model name, voltage specification, serial number, worker name, work date and time, inspection judgment result, inspection data, nonconformity (to be described later) contents, and processing method for nonconformity. Data) is also transmitted to the server 12 via the terminals 14-1 to 14-n.
And recorded (step 4 in FIG. 6).

The data and process data indicating the monitoring results and inspection results sent to the server 12 via the terminals 14-1 to 14-n are used as feedback / feedforward from the server 12. Become.

The work places include “non-conforming”, “interruption”, “work drawing (own process)”, “work drawing (all processes)”, “return”, “end”, "Color settings",
A table 30 on which a barcode such as “setting” is described is displayed (see FIG. 2). By reading this with a barcode reader, the display screen can be switched as appropriate.

It should be noted that the "incompatible" bar code can be read and interrupted if there is any inconsistency in the operation. It should be noted that the process performed when the “unsuitable” barcode is read will be described later in detail.

The "interrupt" bar code can be read to interrupt the operation if necessary. That is, in this manufacturing process management system, as described above, the working time of the worker can be recorded. For this reason, when the work is interrupted during a break time such as a lunch break, the break time is included in the work time on the manufacturing process management system unless the production process management system is notified of the fact. That is, the work time of the worker is recorded as abnormally long. Therefore, when the work needs to be interrupted, such as during a break, the "interrupt" barcode is read to interrupt the operation on the manufacturing process management system.

When the "interrupt" bar code is read, an initial screen is displayed on the display unit 142.

When the "interrupt" barcode is read and the screen returns to the initial screen, the "return" barcode described later is read to switch from the initial screen to the re-input processing screen (see FIG. 13). It is being replaced.
That is, when the "interrupt" barcode is read, the history indicating that the "interrupt" barcode has been read is recorded in this manufacturing process management system. Therefore, by referring to the history, when the “return” barcode is read after the “interruption” barcode is read and the screen returns to the initial screen, the re-entry processing screen is automatically displayed. It has been made like that.

The operator enters the re-input processing screen (see FIG. 13).
In, by selecting an arbitrary operation, the operation can be started from an arbitrary operation stage.

By reading the “work drawing (own process)” barcode, the display in the part drawing display field 304 can be switched to that for the own process.

By reading the “work drawing (all steps)” bar code, the display in the part drawing display column 304 can be switched to that for all steps.

By reading the "return" barcode, the display can be switched to the work immediately before the currently displayed work. As mentioned above,
When the "return" barcode is read after the "interruption" barcode is read and the screen returns to the initial screen, the re-entry processing screen is automatically displayed.

Further, by reading the “end” bar code, the operation can be ended.

Further, by reading the “color setting” bar code, the display color of the display section 142 can be switched.

Further, by reading the “setting” bar code, the setting state of the display section 142 can be switched.

Next, if there is any inconsistency in the work while performing the assembling work with reference to the work diagram screen displayed on the display section 142, the worker uses a bar code reader to read the work diagram screen shown in FIG. Read the nonconforming barcode shown in. Then, the screen display on the display unit 142 is switched to a non-conformance interruption screen (see FIG. 11). Then, the worker can appropriately perform processing for the nonconformity.

Further, the operator can appropriately input a comment in the “nonconforming process” box on the nonconforming suspending screen.

Here, when the operator clicks the “OK” button in the “nonconforming process” box on the nonconforming suspending screen with a mouse or the like, it is possible to return to the initial screen.

When the screen returns to the initial screen after the non-conformity interruption screen is displayed as described above, the non-conformity correction screen (FIG. 1) is automatically provided after a predetermined time (for example, several seconds).
2). That is, when a nonconformity occurs and the nonconformance interruption screen is displayed, the manufacturing process management system records a history indicating that the nonconformity interruption screen is displayed. For this reason, by referring to the history, when the initial screen is displayed after the non-conformance interruption screen is displayed, the non-conformity correction screen is automatically displayed.

The operator can input the non-conformity content, the correction content, the corrector, the division of responsibility, the correction time, and the like in the “re-input process from non-conformity” box on the non-conformity correction screen.

Here, the operator clicks "OK" in the "Re-input process from non-conformity" box on the non-conformity correction screen.
When the button is clicked with a mouse or the like, the screen is automatically switched to a re-input processing screen (see FIG. 13). The worker
By selecting an arbitrary operation on the re-input processing screen (see FIG. 13), the operation can be started from an arbitrary operation stage.

Here, when one work is completed, an ASSY end screen (see FIG. 14) is automatically displayed to prompt the start of the next work.

When all the operations in a certain process are completed, a process completion screen (see FIG. 15) is automatically displayed.
Prompt the start of the next step.

FIGS. 17 to 20 show the case where the work is completed without any inconsistency (FIG. 17), the case where there is an incompatibility and the work is restarted from the middle of the work (FIG. 18), 19 shows the data flow when the work is resumed from (FIG. 19) and when the work is interrupted (FIG. 20).

In any of these cases, as described above, the process data, monitoring data, and inspection data are sent to the server 12 via the terminals 14-1 to 14-n and used.
