<Locking procedure>

FIG. 11 shows the locking procedure of the flange locking management system 2 ( FIG. 1 ) of Embodiment 1. FIG.

In this routine, as shown in FIG. 11, at the start of locking, the operator information 64 is acquired (S201). To obtain the operator information 64 , the operator information 64 may be read from the barcode 86 of the operator tag 84 by a reading mechanism such as a barcode reader.

After this step, it is determined whether or not the operator information 64 has been read in the server 6 (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 can be turned on to display a warning. Thereby, 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 acquired, the warning display is canceled, and the display of the appropriate determination is, for example, a green light, etc., indicating that the acquisition of the operator information 64 has been performed.

If the operator information 64 has been read (YES in S202), the flange information 60 is acquired (S204). To obtain the flange information 60, the flange tag information 92 (B in FIG. 7 ) can be read from the flange tag 30 using a barcode reader or the like in the same manner. In this example, it is not judged whether or not the flange information 60 has been read, but it can be judged that the reading is wrong in the same way as the operator information 64 described above.

After the flange information 60 is read, the gasket information 62 is acquired (S205). To obtain the shim information 62, the shim label information 110 can be read 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 contained in the flange information 60 .

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

Thereby, the gasket 12 suitable for the operator information 64 and the flange information 60 is selected, and the preconditions for locking are adjusted. At this time, automatic selection of the locking condition is performed from the locking condition information (S208).

When the locking conditions are set, the locking tool 18 is used to perform the locking of the nut 16 (S209). The server 6 obtains the locking result information from the sensor 4 (S210). The result information includes the locking results of the aforementioned axial force F, etc.

The server 6 determines 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 error display turns on the red light to inform the operator 82 that the locking result suitable for the locking conditions has not been obtained.

Next, the server 6 records the locking result including the erroneous 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 above-mentioned log information table 70 - 2 on the screen 24 .

<Processing procedure from locking preparation to locking implementation>

Figure 12 shows the processing sequence from locking preparation to locking implementation. Before the flange is locked, the operator information 64 is obtained from the operator tag 84 (S301), next, the flange information 60 is obtained from the flange tag 30 (S302), and then Then, after obtaining the gasket information 62 from the gasket label 32 (S303), 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 matching and determination ( S304 ), it is determined whether or not the gasket 12 fits the flange 10 ( S305 ). Thereby, it is judged whether the selected gasket 12 is suitable for the flange 10 to be locked.

If the gasket 12 is not suitable for the flange 10 (NO in S305), a red light is turned on or the like to report a judgment error (S306), and the process returns to S303. That is, the operator is informed that the gasket 12 is not suitable by the red light, and the operator is urged to replace the gasket 12 .

If the shim 12 is selected again, the shim information 62 is obtained from the shim tag 32 located on the shim 12 thereof (S303), and the image/determination is performed again (S304). As a result, if the gasket 12 is flanged 10 (YES in S305), the green light is turned on to notify that the judgment is correct (S307), and the locking condition can be selected (S308). That is, if the green light is not illuminated, selection of the locking condition is prevented.

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

After selecting the lock condition number, the process proceeds to lock execution (S309). The 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 locking to outputting log information. The locking result is obtained from the sensor 4 ( S401 ), and the locking result is temporarily stored in the temporary memory area 44 - 1 of the memory unit 44 . This locking result includes the detected axial force F of the strain gauge 74 . The log information table 70-1 is created from the locking result.

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 or not the locking result meets the locking condition (S403).

If the locking result matches the locking condition (YES in S403), the green light is turned on to notify that the judgment is appropriate (S404), and if the locking result does not match the locking condition (NO in S403), the red light is turned on , and a judgment error is reported (S407).

A log information table 70-1 is created based on the locking result, and the log information is sorted and processed to create a log information table 70-2 (S405).

Next, the log information table 70-2 is not only written in, for example, the external memory 50, but also output through the display unit 54 (S406).

<Effect of Embodiment 1>

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

(2) After selecting the flange 10, select the gasket 12, compare the gasket information obtained from the gasket 12 with the gasket information located in the flange information, and judge whether it is suitable or not, so the gasket suitable for the flange 10 can be selected. Sheet 12.

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

(4) If it is impossible to confirm whether the gasket 12 is suitable or not through the comparison of the gasket 12, it is prevented from entering the stage of providing locking conditions. Since the locking conditions are selected after the flange 10 and the gasket 12 are determined, the convexity can be realized. A series of management of flange 10, spacer 12 and locking conditions.

(5) Since a suitable locking condition can be automatically selected from the locking condition information through the condition of (4), it is not necessary to force the operator to manage the locking condition, and the burden of the operator can be reduced from the setting of the locking condition. It is possible to avoid automatic setting of locking conditions depending on the operator's experience or intuition, and to prevent troublesome operations using written instructions, or input errors or locking errors caused by written instructions. It can perform high-precision torque management provided by the information of the locking conditions, and can effectively perform locking by utilizing the different axial force F of the bolts of each locking object. By presenting the locking result of the sensor 4 to the operator, it is possible to realize highly accurate flange locking management far beyond the management depending on the operator's personality or intuition.

(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, Reduce the work of each information acquisition.

(7) By attaching information barcodes such as barcodes or QR (Quick Response) (registered trademark) barcodes to the flange label 30 or the spacer label 32, and using a reading device such as a barcode reader, information can be improved. The speed and reliability of acquisition.

(8) When the flange 10 is locked, it can be determined whether the locking conditions are sufficient. Judgment of the adequacy of the locking conditions in the locking process may include: locking defects, defective bolts 14 or nuts 16, defects caused by locking, inappropriate second locking of the same bolt, failure of the locking sequence Wrong, forgetting to lock and other component defects or poor work judgment. The results of these sufficiency judgments can determine whether the locking result is appropriate (OK/NG), as the locking result The result is recorded in the log information. These judgments and recordings are performed in synchronization with the flange locking, so that the work efficiency is not lowered, and a work result with high reliability can be obtained.

(9) The locking result including such appropriateness information is supplied from the sensor 4 to the server 6 and recorded. In the server 6, the locking result can be organized, not only all the information, but also the necessary information can be extracted, edited and made into 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 it in an external computer, the log information table 70-2 can be presented.

(11) By developing the log information table 70-2, the administrator can easily know whether a locking result suitable for the locking conditions is obtained. In the log information table 70-2, it can be seen that the result of the erroneous determination can be known by the appropriateness information in the locking result associated with the flange 10. Since the locking result includes detailed related information such as the work date related to the flange 10, the details of the work result can be easily known.

(12) Since the operator information is obtained in relation to the flange configuration, it is possible to easily know which operator or construction company is responsible and the date from the operation result. Since the gasket information associated with the flange 10 is judged whether it is appropriate or not before locking, the use of an unsuitable gasket can be prevented in advance.
