The log information table 70-1 includes: line information section 70-11, flange information section 70-12, gasket information section 70-13, bolt information section 70-14, and locking condition information section 70-15 , Lock result information section 70-16, Operator ID section 70-17.

As shown in FIG. 10, the log information table 70-2 includes the line information section 70-21, the flange information section 70-22, and the gasket information section similarly to the log information table 70-1 (FIG. 9B). 70-23, locking condition information section 70-25, and operator ID section 70-27, and further includes a construction date section 70-28, an error determination section 70-29, a first lap lock result section 70-30, The final lap lock result section 70-31 and the number of revolutions section 70-32. The worker ID unit 70-27 stores the same worker ID as the worker ID unit 70-17. Thereby, the operator is identified in association with the flange 10. In the log information table 70-2, unlike the log information table 70-1, the bolt information section 70-14 is omitted.

Store the lock date on the construction date section 70-28. Thereby, it is related to the flange 10, and a specific locking day is specified. The error determination unit 70-29 displays a determination result of whether the locking state is suitable for the locking condition. If "OK", it is suitable, and if "NG", it is not.

The number of revolutions is displayed in the number of revolutions section 70-32.

＜ Locking procedure ＞

FIG. 11 shows a locking procedure of the flange lock management system 2 (FIG. 1) of the first embodiment.

In this program, as shown in FIG. 11, when locking is started, the operator information 64 is acquired (S201). To obtain the operator information 64, it is sufficient to read the operator information 64 from the barcode 86 of the operator tag 84 by a reading mechanism such as a barcode reader.

After this step, the server 6 determines whether or not the operator information 64 has been read (S202). If the operator information 64 is not read (NO in S202), an error display is performed on the display unit 54 (S203). For example, a red light may be turned on for warning display. With this, the operator 82 facilitates re-reading of the operator information 64, and the barcode 86 can be read again by the barcode reader. As a result, if the operator information 64 can be obtained, the warning display is canceled, and the display that is appropriately determined is, for example, a bright green light, indicating that the operator information 64 has been acquired.

If the operator information 64 has been read (YES in S202), the flange information 60 is obtained (S204). To obtain this flange information 60, the flange label information 92 (FIG. 7B) may be read from the flange label 30 similarly using a barcode reader or the like. In this example, although it is not determined whether the flange information 60 has been read, the read error can be determined in the same manner as the operator information 64 described above.

After the flange information 60 is read, the shim information 62 is obtained (S205). To obtain the shim information 62, the shim label information 110 can be read in from the barcode 108 of the shim label 32 using a barcode reader or the like.

After obtaining the operator information 64, the flange information 60, and the gasket information 62, it is determined whether the gasket 12 is suitable for the flange 10 (S206). That is, it is determined whether the gasket information 62 obtained from the gasket 12 is suitable for the gasket information included in the flange information 60.

If the gasket 12 is not suitable for the flange 10 (NO in S206), an error display is performed on the display unit 54 (S207). This error display is performed, for example, by turning on a red light. Thereby, the operator 82 is urged to select a suitable gasket 12 again. As a result, when a suitable gasket 12 is selected, the red light is turned off and the green light is turned on.

Thereby, the shim 12 suitable for the operator information 64 and the flange information 60 is selected, and the preconditions for locking are adjusted. At this time, the locking condition is automatically selected from the locking condition information (S208).

When the locking condition is set, the nut 16 is locked using the locking tool 18 (S209). The server 6 obtains locking result information from the sensor 4 (S210). The result information includes the locking result of the axial force F and the like described above.

The server 6 judges whether the locking result is suitable for the locking condition from the obtained result information (S211). If the locking result is not suitable for the locking condition (NO in S211), an error display is performed (S212). The erroneous display turns on the red light to inform the operator 82 that no locking result suitable for the locking condition was obtained.

Next, the server 6 records the locking result including an incorrect judgment (S213). The locking result is recorded in the log information table 70-1 (S214), and the process is completed.

The recorded information can be output and stored in the external memory 50. In addition, the server 6 can display the recorded log information table 70-2 on the screen 24.

<Processing procedure from lock preparation to lock implementation>

FIG. 12 shows the processing procedure from the lock preparation to the lock implementation. Before the flange is locked, the operator information 64 is obtained from the operator label 84 (S301), the flange information 60 is obtained from the flange label 30 (S302), and then the gasket information 62 is obtained from the gasket label 32 ( S303). Then, the comparison and determination of the gasket information included in the flange information 60 and the gasket information showing the actual gasket 12 are performed (S304). In this photographing and determination (S304), it is determined whether the gasket 12 is suitable for the flange 10 (S305). Thereby, a judgment is made as to whether the selected gasket 12 is suitable as the flange 10 to be locked.

If the gasket 12 is not suitable for the flange 10 (NO in S305), a judgment error is reported by lighting a red light or the like (S306), and the process returns to S303. In other words, the operator is notified of the unsuitability of the gasket 12 with a bright red light, and the operator is prompted to replace the gasket 12.

When the shim 12 is selected again, the shim information 62 is obtained from the shim label 32 located on the shim 12 (S303), and a new photo / determination is performed (S304). As a result, if the flange 10 of the gasket 12 is YES (YES in S305), a bright green light is reported to determine whether the determination is appropriate (S307), and the locking condition can be selected (S308). That is, if the green light is not lit, the selection of the lock condition is prevented.

When a locking condition is selected, a locking condition table 68 located in the memory section 44 is referred to, and a locking condition number is selected from the locking condition table 68 (S308).

After the lock condition number is selected, the lock execution is performed (S309). This locking is performed by the operator 82 using the locking tool 18.

＜ Processing procedure from locking to outputting log information ＞

FIG. 13 shows the processing procedure from the locking to the output of log information. The locking result is obtained from the sensor 4 (S401), and the locking result is temporarily stored in the temporary storage area 44-1 of the storage unit 44. This locking result includes the detected axial force F of the strain gauge 74. From this locking result, a log information table 70-1 is created.

With regard to the locking result, the locking condition number X of the locking condition table 68 is referred to, and the locking condition is determined (S402). In this determination, it is determined whether the locking result matches the locking condition (S403).

If the locking result meets the locking conditions (YES in S403), the green light is turned on to inform the judgment (S404). If the locking result does not meet the locking conditions (NO in S403), the red light is turned on. , And a judgment error is reported (S407).

According to the locking result, a log information table 70-1 is prepared, and the log information is organized and processed to create a log information table 70-2 (S405).

Next, the log information table 70-2 is written in, for example, the external memory 50 and also output through the display unit 54 (S406).

<Effect of Example 1>

(1) When the flange is locked, the locking condition information is read to the server 6 to determine whether the locking result detected by the sensor 4 is appropriate, thereby improving the reliability of the locking implementation.

(2) After selecting the flange 10, select the gasket 12 and compare the gasket information obtained from the gasket 12 with the gasket information located at the flange information to determine whether it is appropriate or not. Sheet 12.

(3) If the shim 12 is not suitable, the operator may be prompted to replace the shim 12 by reporting a warning judgment, and select a suitable shim 12.

(4) If it is impossible to confirm whether the gasket 12 is suitable through the comparison of the gaskets 12, it is prevented from entering the stage of providing the locking conditions. Since the locking conditions are selected after the flange 10 and the gasket 12 are determined, the convexity can be achieved A series of management of edge 10, gasket 12 and locking conditions.

(5) Since the condition (4) can automatically select the appropriate locking condition from the locking condition information, there is no need to force the operator to manage the locking condition, and the operator can reduce the burden from the setting of the locking condition. It can avoid automation that depends on the operator's experience or intuitive setting of locking conditions, and can prevent tedious work using written instructions, or input errors or locking errors caused by written instructions. It can perform high-precision torque management provided by the locking condition information, and can use the different axial force F of each bolt to be locked efficiently. By prompting the operator of the locking result of the sensor 4, it is possible to achieve flange locking management with a high degree of accuracy far beyond the individuality or intuitive management of the operator.

(6) Since the flange information is obtained from the flange label 30 attached to the flange 10 and the gasket information is obtained from the gasket label 32 attached to the gasket 12, the reliability of the flange information and the gasket information can be improved. Reduction of various information acquisition tasks.

(7) By attaching a bar code or a QR (Quick Response) (registered trademark) bar code or other information bar code to a flange label 30 or a gasket label 32 and using a reading device such as a bar code reader, the information can be improved. Fast and reliable acquisition.

(8) When the flange 10 is locked, it can be determined whether the locking condition is sufficient. Judgment of the adequacy of the locking conditions during locking may include: locking defects, bad bolts 14 or nuts 16, bad occurrences due to locking, improper second locking of the same bolt, locking sequence Good or bad judgments about component defects such as mistakes, forgetting to lock, or poor operation. The results of these adequacy judgments can determine whether the locking result is appropriate (OK / NG) and recorded in the log information as the locking result. These judgments and records are synchronized with the flange locking, and are performed simultaneously, so that the work efficiency is not reduced, and reliable work results can be obtained.

(9) The locking result containing such appropriate information is provided from the sensor 4 to the server 6 and recorded. In the server 6, the locking results can be organized, not only all the information, but also necessary information can be extracted and edited to create log information.

(10) The locking result information can be collected in the log information tables 70-1 and 70-2 and transferred from the server 6 to the external memory 50. By removing the external memory 50 from the server 6 and installing the external memory 50 on an external computer, the log information table 70-2 can be prompted.

(11) By expanding the log information table 70-2, the manager can easily know whether a locking result suitable for the locking condition is obtained. From the log information table 70-2, it is known that the result of the erroneous determination is obtained by using the appropriate information in the locking result related to the flange 10. Since the locking result includes detailed related information such as a working day related to the flange 10, details of the working result can be easily known.

(12) Since the operator information is obtained in connection with the flange structure, it is easy to know from the operation result which operator or construction company is responsible and the date. Since the gasket information related to the flange 10 is judged before it is properly locked, the use of inappropriate gaskets can be prevented in advance.
