The first rotation locking result section 98-30 shows the locking result (torque) of the first rotation of the plurality of bolts 16 located on the flange 12 for locking. The final rotation locking result portion 98-31 shows the final rotation locking result (torque) of the plurality of bolts 16 that are locked by the turns. The number of revolutions 98-32 indicates the number of revolutions.

＜ Locking procedure ＞

FIG. 12 shows a locking procedure of the flange lock management system 2 (FIG. 1) related to the first embodiment.

In this procedure, as shown in FIG. 12, the operator information 94 is acquired at the beginning of the locking (S201). Regarding the acquisition of the operator information 94, the operator information 94 may be read by the barcode reader 86 and the barcode 116 of the operator tag 93.

After this step, the controller 6 determines whether the operator information 94 has been read (S202). If the operator information 94 has not been read (NO in S202), an error is indicated in the display unit 84 (S203), and for example, the red lamp 84-2 is turned on. With this, the operator 112 can be urged to read the operator information 94 again, and read the barcode 116 again with the barcode reader 86. As a result, if the operator information 94 is available, the red light 84-2 is turned off and the green light 84-1 is turned on, indicating that the operator information 94 has been obtained.

If the operator information 94 has been read (YES in S202), the flange information 90 is obtained (S204). The acquisition of the flange information 90 is similar to the operator information 94, and the flange label information 124 (FIG. 8B) may be read by the flange label 42 using the barcode reader 86. Although it is not determined whether the reading of the flange information 90 is performed in this example, the reading error may be determined in the same manner as the already mentioned operator information 94.

After the flange information 90 is read, the shim information 92 is obtained (S205). Regarding the acquisition of the gasket information 92, the barcode information can be read by the barcode reader 86 and the barcode 134 of the gasket label 44.

After obtaining the operator information 94, the flange information 90, and the gasket information 92, it is determined whether the gasket 14 is suitable for the flange 12 (S206). That is, it is determined whether the gasket information 92 obtained by the gasket 14 is suitable for the gasket information included in the flange information 90.

If the gasket 14 is not suitable for the flange 12 (NO in S206), an error is indicated in the display unit 84 (S207). This indicates that, for example, the red light 84-2 is turned on. In this way, the operator 112 is urged to make a suitable selection of the gasket 14. As a result, if the appropriate spacer 14 is selected, the red lamp 84-2 is turned off, and the green lamp 84-1 is turned on.

Thereby, the gasket 14 which is suitable for the operator information 94 and the flange information 90 is selected, and the condition before locking is achieved. At this time, the locking condition is automatically selected based on the locking condition information (S208), and the locking condition is set for the locking tool 4 by the controller 6.

After the locking conditions are set, the nut 18 is locked using the locking tool 4 (S209). The controller 6 obtains locking result information from the locking tool 4 (S210). The result information includes the tightening results of the torque τ and the angle of rotation of the nut.

Based on the result information obtained by the controller 6, it is determined whether the locking result is suitable for the locking condition (S211). If the locking result is not suitable for the locking condition (No in S211), an error is indicated (S212). The indication is that the red light 84-2 lights up, and informs the operator 112 that the locking result suitable for the locking condition is not obtained.

Then, the controller 6 records the locking result including the judgment error (S213). The locking result is recorded in the log information table 98-1 (S214), and the process is completed.

The recorded information can be output to the external memory 88. The external memory 88 can be mounted on the server 8 and the already mentioned record information table 98-2 can be displayed on the display 40 of the server 8.

＜ Process from lock preparation to lock implementation ＞

FIG. 13 shows the processing procedure from the preparation of locking to the implementation of locking. Before the flange is locked, the operator information 94 is obtained from the operator label 93 (S301), the flange information 90 is obtained from the flange label 42 (S302), and the gasket information 92 is obtained from the gasket label 44 (S303). ), And then the comparison and determination of the gasket information included in the flange information 90 and the gasket information indicating the actual gasket 14 are performed (S304). This comparison and determination (S304) is a determination of whether the gasket is suitable for the flange (S305). By this, it is judged whether the selected gasket is suitable for the flange which is a locking object.

If the gasket 14 is not suitable for the flange 12 (NO in S305), the red light 84-2 is turned on to indicate an error (S306), and the process returns to S303. That is, the operator 112 is notified that the gasket 14 is not suitable by lighting the red light 84-2, and the operator 112 is urged to replace the gasket 14.

When the shim 14 is selected again, the shim information 92 is obtained from the shim label 44 of the shim 14 (S303), and comparison and determination are performed again (S304). If the result is that the gasket 14 fits the flange 12 (YES in S305), the green light 84-1 is turned on to indicate suitability (S307), and the locking condition can be selected (S308). That is, if the green light 84-1 is not lit, the selection of the locking condition is prevented.

The locking condition is selected by referring to the locking condition table 96 located in the memory section 76, and the locking condition number is selected from the locking condition table 96 (S308).

The lock condition number is input to the lock tool 4 (S309), and the lock is performed (S310). This locking is performed by the operator 112 using the locking tool 4.

＜ Processing procedure from locking to outputting log information ＞

Figure 14 shows the processing procedure from the locking to the output of log information. The locking result is obtained by the locking tool 4 (S401), and the locking result is temporarily stored in the temporary memory area 76-1 of the memory section 76. The locking result includes the torque detected by the torque sensor 52. From the locking result, a log information table 98-1 is created.

With regard to the locking result, referring to the locking condition No. X of the locking condition table 96, the locking result is determined (S402). In this determination, it is determined whether the locking result meets the locking condition (S403).

If the locking result meets the locking conditions (YES in S403), the green light 84-1 lights up to indicate suitability (S404). If the locking result does not meet the locking conditions (No in S403), then The red light 84-2 lights up to indicate that it is not suitable.

Based on the locking result, a log information table 98-1 is prepared, and the log information is organized and processed to create a log information table 98-2 (S405).

Then, for example, the log information table 98-2 is written to the external memory 88, and the external memory 88 is used as a medium to be provided to the server 8 and a prompt can be performed (S406). The log information table 98-2 may also be transmitted from the controller 6 to the server 8 by wireless.

<Effect of Example 1>

(5) If the gasket 14 is not suitable, the operator can be urged to replace the gasket 14 by turning on the red light 84-2, so that he can choose a suitable gasket 14.

(6) If it is impossible to confirm the suitability of the gasket 14 after the comparison of the gaskets 14, it is prevented from moving to the stage of providing the locking conditions. After the flanges 12 and the gaskets 14 are determined, the locking conditions are selected, so that the flanges can be realized. 12. Management of gasket 14 and the entire string of locking conditions.

After the conditions of (7) and (6) above, the appropriate locking conditions are automatically selected by the locking condition information, so the operator does not need to bear the management of the locking conditions, and the locking conditions can be set to reduce the burden on the operator. Can avoid relying on the operator's experience and intuition to set the locking conditions and automate it. In addition, it can prevent tedious operations caused by written instructions, input errors and locking errors caused by written instructions. Since the locking condition can be individually and specifically provided to the controller 6 by the server 8, a general operation such as locking all bolts with the same torque can be avoided, and a delicate locking result can be achieved. It can perform high-precision torque management provided by the information of the locking conditions, and can reliably and efficiently perform locking with different torques τ according to the bolts of each locking object. It can realize the management of flange locking much higher than the operator's personality and intuitive management.

(9) Attach information codes such as bar codes and QR codes (registered trademarks) to flange labels 42 and gasket labels 44. By using input devices such as bar code reader 86, the speed of information acquisition can be improved and reliability.

(10) In the locking of the flange 12, it can be determined whether the locking condition is satisfied. Judgment of the satisfaction of the locking conditions during locking may include locking defects, poor bolts 16 or nuts 18, poor due to locking, improper secondary locking of the same bolt, incorrect locking sequence, Judging the pros and cons of component defects and poor operation such as missing locks. The results of such satisfaction judgments and the suitability of the locking result (OK / NG) can be determined and recorded in the log information as the locking result. Since these judgments and records are performed simultaneously with the flange locking, it is possible to obtain a highly reliable operation result without reducing the operation efficiency.

(11) The locking result including the suitability information may be provided by the locking tool 4 to the controller 6 and recorded, and the controller 6 may provide the log information to the server 8. The controller 6 can sort the locking results. In addition to all the information, it can also retrieve and compile necessary information to produce log information.

(12) The locking result information can be integrated in the log information tables 98-1 and 98-2 and transmitted from the controller 6 to the external memory 88. The external memory 88 can be detached from the controller 6 and installed in the server 8 to prompt the log information table 98-2.

(13) By expanding the log information table 98-2, the manager can easily know whether a locking result suitable for the locking condition is obtained. In the log information table 98-2, it is possible to know the result of the erroneous determination as suitable information for the locking result associated with the flange 12. Since the locking result includes detailed related information such as the working day associated with the flange 12, the details of the working result can be easily known.

(14) Since the operator information is obtained in association with the flange, the operator and construction company can easily know which operator and construction company the date of the operation. In particular, since the gasket information associated with the flange 12 is judged as being suitable before being locked, it is possible to prevent situations where a gasket is not suitable.
