<Locking procedure>

Figure 12 shows the locking procedure of the flange locking management system 2 (Figure 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 can be read by the barcode 116 of the operator tag 93 by the barcode reader 86.

After this step, the controller 6 performs the read operation The judgment of the employee information 94 (S202). If the operator information 94 is not read ("No" in S202), an error is indicated in the display unit 84 (S203), for example, the red light 84-2 is lit. Thereby, the operator 112 can be supervised to re-read the operator information 94, and the barcode 116 can be read by the barcode reader 86 again. As a result, if the operator information 94 can be obtained, the red lamp 84-2 is turned off and the green lamp 84-1 is lit, 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). Regarding the acquisition of the flange information 90, the same as the operator information 94, the flange label information 124 (FIG. 8B) can be read from the flange label 42 using the barcode reader 86. Although in this example, it is not determined whether the reading of the flange information 90 is performed, it is also possible to determine a reading error in the same manner as the operator information 94 mentioned above.

After the flange information 90 is read, the gasket information 92 is obtained (S205). Regarding the acquisition of the gasket information 92, the barcode reader 86 can read the gasket label information from 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 from 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 section 84 (S207). This indicates that the error is, for example, to light up the red light 84-2. In this way, the operator 112 is urged to select a suitable gasket 14 again. As a result, if a suitable gasket 14 is selected, the red light 84-2 is turned off and the green light 84-1 is turned on.

In this way, the gasket 14 suitable for the operator information 94 and the flange information 90 is selected to achieve the pre-locking conditions. At this time, the locking condition is automatically selected from the locking condition information (S208), and the locking condition is set for the locking tool 4 by the controller 6.

After setting the locking conditions, use the locking tool 4 to lock the nut 18 (S209). The controller 6 obtains the locking result information from the locking tool 4 (S210). The result information includes the torque τ and the tightening result of the nut rotation angle mentioned.

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), it means an error (S212). It means that the error is to turn on the red light 84-2 to inform 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 log information can be output to the external memory 88. The external memory 88 can be installed in the server 8 and the display 40 of the server 8 can display the mentioned log information table 98-2.

<Processing procedures from preparing for locking to implementing locking>

Figure 13 shows the processing procedure from preparing for locking to implementing locking. Before locking the flange, the operator information 94 is obtained from the operator tag 93 (S301), then the flange information 90 is obtained from the flange tag 42 (S302), and then the gasket information 92 is obtained from the gasket tag 44 (S303 ), after that, implement The comparison and determination of the gasket information included in the flange information 90 and the gasket information representing the actual gasket 14 (S304). This comparison and determination (S304) is to determine whether the gasket is suitable for the flange (S305). In this way, it is judged whether the selected gasket is suitable for the flange as the locking object.

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

If the gasket 14 is selected again, the gasket information 92 is obtained from the gasket tag 44 of the gasket 14 (S303), and then the 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 lit to indicate the fit (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 will be prevented.

The selection of the locking condition refers to the locking condition table 96 located in the memory part 76, and the locking condition number is selected from the locking condition table 96 (S308).

The locking condition number is input into the locking tool 4 (S309), and then the locking is performed (S310). The implementation of the locking is performed by the operator 112 with the locking tool 4.

<Processing procedures from locking to outputting log information>

Figure 14 shows the processing procedure from locking to outputting 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 unit 76. The locking result package The torque detected by the torque sensor 52 is included. From the locking result, a log information table 98-1 is created.

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

If the locking result meets the locking condition ("Yes" in S403), the green light 84-1 is lit to indicate suitability (S404); if the locking result does not meet the locking condition ("No" in S403), the The red light 84-2 lights up to indicate that it is not suitable.

A log information table 98-1 is created based on the locking result, and the log information is sorted and processed to create a log information table 98-2 (S405).

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

<Effects of Example 1>

(1) The administrator provides the locking conditions to the controller 6 from the server 8, so the locking conditions can be managed strictly and fairly, and excellent traceability can be constructed.

(2) The operator who performs the locking of the flange 12 is provided with the controller 6 storing the information of the locking condition, so the management of the locking condition becomes easy and the burden of the operator can be reduced.

(3) Since the server 8 provides the locking condition information to the controller 6 when locking the flange, the locking condition located in the controller 6 can be used The information restricts the implementation of the locking, so that the reliability of the implementation of the locking is improved.

(4) After the flange 12 is selected, the gasket 14 is selected, and the gasket information obtained by the gasket 14 is compared with the gasket information in the flange information to determine whether it is suitable or not, so you can select the suitable flange 12 Gasket 14.

(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 the gasket 14 can be selected.

(6) If the comparison of the gasket 14 cannot confirm whether the gasket 14 is suitable, stop moving to the stage where the locking conditions are provided. After the flange 12 and the gasket 14 are determined, the locking conditions can be selected, so the flange can be realized. 12. Management of the entire string of gaskets 14 and locking conditions.

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

(8) Because it is obtained from the flange tag 42 attached to the flange 12 The flange information is obtained from the gasket label 44 attached to the gasket 14. Therefore, the reliability of the flange information and the gasket information is high, and the operation of obtaining various information can be reduced.

(9) Attach information codes such as barcodes and QR codes (registered trademarks) to the flange label 42 and the gasket label 44, so that the speed of obtaining information can be improved by using input devices such as the barcode reader 86 reliability.

(10) In the locking of the flange 12, it can be judged whether the locking conditions are met. The judgment of the satisfaction of the locking conditions during locking can include locking defects, defective bolts 16 or nut 18, defects caused by locking, improper secondary locking of the same bolt, wrong locking sequence, Judgment of the pros and cons of component defects such as missing locking and poor operation. The result of the satisfaction judgment and the suitability of the locking result (OK/NG) can be judged and recorded in the log information as the locking result. Since these judgments and records are performed simultaneously and simultaneously with the flange locking, it is possible to obtain highly reliable operating results without reducing operating efficiency.

(11) Such a locking result including suitability information can be provided by the locking tool 4 to the controller 6 and recorded, and provided by the controller 6 as log information to the server 8. The controller 6 can sort the locking results, and in addition to all the information, it can also capture and compile necessary information to make log information.

(12) The locking result information can be integrated in the log information tables 98-1, 98-2 and sent from the controller 6 to the external memory 88. The external memory 88 can be removed 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 the locking result suitable for the locking condition is obtained. In the log information table 98-2, the result of the error judgment can be known as the suitability information of the locking result associated with the flange 12. Since the locking result includes detailed related information such as the operation date associated with the flange 12, the details of the operation result can be easily known.

(14) Since the operator information is obtained in association with the flange, it is easy to know which operator and construction company undertakes the work together with the date of the work. In particular, since the gasket information associated with the flange 12 is judged whether it is suitable or not before being locked, it is possible to prevent the use of unsuitable gaskets.
