  FIG. 1 is a configuration diagram of a production line drawing management system according to an embodiment of the present invention. In this figure, the designer M1 in the design department 2, the manager M2 in the management department 3, and the worker M3 in the manufacturing department 4 can exchange data with each other via the network 1. Yes.

  That is, the design department 2 is provided with a design department terminal device 5 connected to the network 1 and a design department database 6 connected to the design department terminal device 5.

  The management department 3 is provided with a management department terminal device 7 connected to the network 1 and a management department database 8 connected to the management department terminal device 7. The management department terminal device 7 is connected to the management department IC tag reading / writing device 9 and the IC tag mounting device 10.

  The management department terminal device 7 outputs a two-dimensional data drawing 11, and barcode information 12 as drawing specifying information is added to the two-dimensional data drawing 11.

  The management department IC tag reading / writing device 9 is capable of reading and writing with respect to the IC tag, and here, the accompanying information is written to the IC tag 13.

  The IC tag used in the present invention is also called RFID (Radio Frequency IDentification), and is a small chip of several millimeters size made of a semiconductor element. Then, information is read / written by performing wireless communication with the IC tag reading / writing device.

  The IC tag attaching device 10 attaches the IC tag 13 written by the management department IC tag reading / writing device 9 to the two-dimensional data drawing 11 output by the management department terminal device 7. is there.

  The manufacturing department 4 is provided with a manufacturing department terminal device 14 connected to the network 1 and a manufacturing department IC tag reading / writing device 15 connected to the terminal apparatus 14.

  The manufacturing department IC tag reading / writing device 15 is capable of reading and writing to the IC tag 13, and is attached to the two-dimensional data drawing 11 distributed from the management department 3 to the manufacturing department 4 here. The IC tag 13 is read.

  Next, the processing operation of the system of FIG. 1 configured as described above will be described for each department with reference to the flowcharts of FIGS.

  FIG. 2 is a flowchart for explaining the processing operation in the design department 2. First, the designer M1 creates a three-dimensional data drawing using the design department terminal device 5 (step 21), and further creates a two-dimensional data drawing based on the three-dimensional data drawing (step 22).

  In this case, the designer M1 asks the manufacturing department 4 to refer to the 3D data drawing for complicated shapes for which it is difficult to accurately create the 2D data drawing. Let's create a drawing. Further, even when high accuracy is required, the two-dimensional data drawing is simplified and dimensional tolerance values are described in the drawing, and the manufacturing department 4 refers to the three-dimensional data drawing. The designer M1 describes in the 2D data drawing that the 2D data drawing is simplified as described above, and that the 3D data drawing should be referred to in the manufacturing process, and further, the 2D data drawing and the 3D data drawing. Two-dimensional / three-dimensional correspondence information (that is, drawing accompanying information) indicating a correspondence relationship with a drawing using a drawing number or the like is created (steps 23 to 25).

  Next, the designer M1 creates drawing image data based on the created two-dimensional data drawing (step 26), and the drawing information such as the drawing number and revision number is added to the drawing image data as barcode information 12. (Step 27). Then, the three-dimensional data drawing, the two-dimensional data drawing, the drawing image data, the two-dimensional / three-dimensional correspondence information, etc. created so far are stored in the design department database 6 (step 28).

  Thereafter, the designer M1 checks whether or not the creation of all the drawings has been completed (step 29). If not completed, the designer M1 returns to step 21 to start creating the next drawing. Complete design work.

  FIG. 3 is a flowchart for explaining the processing operation in the management department 3. The manager M2 fetches each data created in advance by the designer M1 and stored in the design department database 6 into the management department database 8 via the management department terminal device 7.

  The manager M2 first extracts the image data for drawing of a predetermined drawing number from the management department database 8, and displays it on the screen of the management department terminal device 7 (step 31). Then, the manager M2 determines whether or not an instruction to refer to the three-dimensional data drawing is described in the image data (step 32). If so, the manager M2 uses the management department terminal device 7 for the management department. The IC tag reading / writing device 9 is caused to output a write command, and the two-dimensional / three-dimensional correspondence information stored in advance in the management department database 8 is written to the IC tag 13 as drawing accompanying information (step 33). ).

  Next, the manager M2 causes the management department terminal device 7 to output the two-dimensional data drawing 11 to which the barcode information 12 as the drawing specifying information is added (step 34). Then, if there is an IC tag 13 to be attached to the two-dimensional data drawing 11, the manager M 2 converts the IC tag 13 in which the two-dimensional / three-dimensional information is written by the IC tag attaching device 10 into the two-dimensional data drawing 11. (Step 35). That is, the barcode information 12 which is the drawing identification information is read by the IC tag attaching device 10, and the IC tag 13 having the drawing number that matches the drawing number included in the barcode information 12 is displayed on the two-dimensional data drawing 11. To be attached to.

  Thereafter, the manager M2 checks whether or not the drawing and the attachment of the IC tag 13 are completed for all the drawings (step 36). If not completed, the manager M2 returns to step 31 to display the next drawing. The screen is displayed, and if it is finished, the drawing work is completed.

  FIG. 4 is a flowchart for explaining the processing operation in the manufacturing department 4. First, the worker M3 obtains the two-dimensional data drawing 11 distributed from the management department 3 (step 41). Then, it is checked whether or not the IC tag 13 is attached to the two-dimensional data drawing 11 (step 42). If it is attached, the IC tag 13 is read by the manufacturing department IC tag reading / writing device 15. (Step 43).

  Then, the two-dimensional / three-dimensional correspondence information as drawing accompanying information read by the manufacturing department IC tag reading / writing device 15 is output to the manufacturing department terminal device 14. Thereby, the manufacturing department terminal device 14 takes out the three-dimensional data corresponding to the two-dimensional data drawing 11 obtained by the worker M3 from the management department database 8 via the management department terminal device 7 (such as transmission abnormality). In this case, it can be taken out from the design department database 6 via the design department terminal 5), and this is automatically displayed on the screen as a three-dimensional data drawing (step 44). The worker M3 performs a manufacturing operation while watching the screen on which the three-dimensional data drawing is displayed (of course, this screen can be printed out if necessary) (step 45).

  At this time, the accompanying information read by the manufacturing department IC tag reading / writing device 15 includes process identification information such as a process number in addition to the two-dimensional and three-dimensional correspondence information. The device 14 transmits the process specifying information to the management department terminal device 7. The management department terminal device 7 stores the received process specifying information in the management department database 8 as management information. The manager M2 can grasp the progress of the process from the reception of such process specifying information and the reception date and time.

  After step 45, the operator M3 checks whether or not all the drawings have been completed (step 46). If not completed, the process returns to step 41 to obtain the next drawing.

  On the other hand, when all the drawings have been completed, the worker M3 collects all the two-dimensional data drawings 11 to which the IC tags 13 are attached, and uses the manufacturing department IC tag reading / writing device 15 to perform the IC. Process end information indicating the end of the process is written in the tag 13 (step 47). At this time, the process end information written by the manufacturing department IC tag reading / writing device 15 is notified to the management department 3 (step 48).

  That is, the process end information is transmitted to the management department terminal device 7 via the network 1 by the manufacturing department terminal device 14 and stored in the management department database 8. Therefore, the manager M2 can automatically acquire management information indicating that each process has been completed. In addition, after the process in the manufacturing department 4 is completed, all the two-dimensional data drawings 11 distributed to the manufacturing department 4 are collected by the management department 3, but the management department 3 then mistakenly moves to another manufacturing department. Even if this drawing is distributed, since the process end information is written in the IC tag 13, it is possible to prevent the manufacturing department from performing the work related to the two-dimensional data drawing 11.

  According to the system having the configuration shown in FIG. 1 described above, the worker M3 manufactures the IC tag 13 attached to the two-dimensional data drawing 11 by reading the IC tag reading / writing device 15 for manufacturing department. The screen display of the three-dimensional data drawing by the department terminal device 14 can be easily performed. In other words, the worker M3 does not need to know the operation procedure of the computer, but can easily bring the IC tag 13 close to a predetermined location of the IC tag reading / writing device 15 for manufacturing department. Can display three-dimensional data.

  Therefore, when the product shape is complicated, the designer M1 does not need to create an accurate 2D data drawing based on the 3D data drawing, and a simple 2D data drawing and a 3D data drawing displayed on the screen Will be used together. Therefore, according to the configuration of FIG. 1, not only the worker M3 but also the designer M1's labor is greatly reduced.

  On the other hand, since the manager M2 has to add the barcode information 12 or attach the IC tag 13, at first glance, it seems that extra work is increased compared to the conventional case. However, the 2D data drawing 11 can be distributed to the manufacturing department 4 including various information in the drawing accompanying information of the IC tag 13 and the process written by the operator M3 after the process of the manufacturing department 4 is completed. Since information and the like can be fed back as management information, it is possible to compensate for the increased work and to obtain a surplus merit.

  The present invention broadly encompasses the following forms in addition to the above-described embodiments.

(1) In addition to an instruction that the three-dimensional data drawing should be referred to for the accompanying information written in the IC tag 13 by the IC tag reading / writing device 9 for the management department, various information in the process of the manufacturing department 4 Notes can be included. The manufacturing department terminal device 14 can display the precautions on the screen based on the reading operation of the manufacturing department IC tag reading / writing device 15.

(2) In addition, the drawing accompanying information can include work difficulty level information in the process of the manufacturing department 4. For example, “A” is displayed when the combination of curved surfaces of the product is complicated and the dimensional tolerance is strict, and “B” is displayed when the product processing is complicated. It is possible to add the level information to the two-dimensional data drawing 11. Furthermore, when displaying the task difficulty level information divided into levels on the manufacturing department terminal device 14, it is possible to alert the operator M3 by displaying different screens such as color-coded according to the level. It is.

(3) The IC tag 13 is not necessarily attached to all the two-dimensional data drawings. For example, when the product shape is simple, the worker M3 can grasp the shape from the two-dimensional data drawing and does not need to refer to the three-dimensional data drawing. However, for a plurality of drawings having a parent-child relationship, various management information between the management department 3 and the manufacturing department 4 can be obtained if the IC tag 13 is always attached to the parent drawing even if the product shape is simple. Can be exchanged.
