The flange label 30 is an example of the 1 st information label. The gasket label 32 is attached to the gasket 12 before fastening, for example, and displays gasket information. The shim tag 32 is an example of the 2 nd information tag.
The server 6 includes, for example: a management function unit 34 that performs a fastening management process of the flange 10; and a storage/display function unit 36 having a function of storing a database including fastening conditions and log information, and a function of displaying the database and the log information. In the server 6, when the fastening management process is executed, the management function portion 34 reads the fastening condition information associated with the flange 10 from the storage/display function portion 36 (S101).
The management function unit 34 acquires flange information from the flange label 30 (S102). The flange information includes pad information indicating a pad matching the flange to which the flange label 30 is attached.
The gasket information is acquired from the gasket label 32 (S103), and the gasket information included in the flange information is compared with the gasket information acquired from the gasket label 32 (S104).
If the gasket 12 is matched with the flange 10 (yes at S105), the management function section 34 selects a matched fastening condition from the fastening condition information (S106).
If the gasket 12 does not match the flange 10 (NO in S105), an error display is made (S107), prompting the operator to replace the matching gasket 12.
When the selection of the fastening condition is completed, the fastening process using the fastening tool 18 is started. The sensor 4 detects the axial force F applied to the bolt 14 as fastening information during or after fastening (S108).
The management function unit 34 of the server 6 acquires fastening information during or after fastening from the sensor 4 (S109), and evaluates whether or not the fastening of the flange 10 matches the fastening condition (S110).
The management function unit 34 generates fastening result information including at least the fastening conditions and the evaluation results in association with the flange 10, and notifies the storage/display function unit 36 of the fastening result information (S111). The storage/display function section 36 displays the supplied fastening result information on the monitor 24 (S112).
The relationship between the above-described processes a) to g) and steps in the processing procedure is as follows.
a) Acquisition of fastening condition information associated with the flange 10: s101
b) Acquisition of flange information of the flange 10: s102
c) Acquisition of gasket information of the gasket 12: s103
d) Comparison of the gasket information included in the flange information with the gasket information acquired from the gasket 12: s104
e) If the flange 10 is matched with the gasket 12, the fastening condition is selected from the fastening condition information: s105, S106
f) Acquisition of fastening information during fastening or after fastening from the sensor 4, evaluation of whether fastening is matched with fastening conditions: s109 and S110
g) Fastening result information including at least the fastening condition and the evaluation result is presented in association with the flange 10: s111, S112
< effects of one embodiment >
(1) The server 6 selects the fastening condition matching the flange 10 and the spacer 12 from the stored fastening condition information, and evaluates the fastening information detected by the sensor 4 based on the fastening condition, thereby monitoring whether or not the proper fastening is performed, avoiding a fastening error, and realizing the proper fastening regardless of the experience of the operator.
(2) Since the flange information acquired from the flange label 30 includes the gasket information indicating the matched gasket 12 and the gasket information is compared with the gasket information acquired from the gasket label 32 to determine whether or not the gasket is matched with the flange, it is possible to prevent the gasket from being erroneously selected for the specified flange, and it is possible to realize the collective management of the flange, the gasket, and the fastening condition. As a result, flange fastening management with high reliability can be achieved.
(3) Since the fastening condition cannot be selected if the selected spacer 12 does not match the flange 10 to be fastened, it is possible to prevent an operator from selecting an error or setting an error of the fastening condition, reduce the burden on the operator, and improve the reliability of fastening.
(4) Since whether or not the fastening state matches the fastening condition is evaluated using the fastening information during fastening or after fastening detected from the bolt 14, the degree of dependence on the operator can be reduced, and fastening errors can be avoided or reduced.
(5) The fastening result information including the fastening condition and the evaluation result of fastening can be recorded and presented, the monitoring and confirmation of the fastening state during fastening can be easily performed, and the past fastening state can be confirmed based on the recorded fastening information.

< fastening Process >
Fig. 11 shows a process of fastening of the flange fastening management system 2 (fig. 1) of embodiment 1.
In this process, as shown in fig. 11, when fastening is started, operator information 64 is acquired (S201). When the operator information 64 is acquired, the operator information 64 may be read from the barcode 86 of the operator label 84 by a reading means 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 may be performed on the display unit 54 (S203), for example, a red light may be turned on as a warning display. This prompts the operator 82 to read the operator information 64 again, and the barcode reader can read the barcode 86 again. As a result, if the operator information 64 is successfully acquired, the warning display is canceled, and, for example, the display determined to be appropriate is turned on to display that the operator information 64 has already been acquired.
If the operator information 64 is read (yes in S202), the flange information 60 is acquired (S204). When the flange information 60 is acquired, similarly, the flange label information 92 (B in fig. 7) may be read from the flange label 30 using a barcode reader or the like. Although the determination as to whether or not the flange information 60 has been read is not made in this example, a determination as to a read error may be made in the same manner as the above-described operator information 64.
After the flange information 60 is read, the shim information 62 is acquired (S205). When the pad information 62 is acquired, the pad label information 110 may be read from the barcode 108 of the pad label 32 by a barcode reader or the like.
After the operator information 64, the flange information 60, and the gasket information 62 are acquired, it is determined whether or not the gasket 12 is matched with the flange 10 (S206). That is, it is determined whether or not the shim information 62 acquired from the shim 12 matches the shim information included in the flange information 60.
If the gasket 12 is not matched with the flange 10 (no in S206), an error display is performed on the display portion 54 (S207). The error display is performed, for example, by turning on a red light. Thereby prompting the operator 82 to reselect the matching shim 12. As a result, if the matching pad 12 is selected, the red light is turned off and the green light is turned on.
This selects the operator information 64 and the spacer 12 matching the flange information 60, and satisfies the fastening precondition. At this time, the fastening condition is automatically selected from the fastening condition information (S208).
When the fastening condition is set, fastening of the nut 16 is performed using the fastening tool 18 (S209). The server 6 acquires fastening result information from the sensor 4 (S210). The result information includes the fastening result such as the axial force F.
The server 6 determines whether or not the fastening result matches the fastening condition based on the acquired result information (S211). If the fastening result does not match the fastening condition (NO in S211), an error display is made (S212). The error display lights up a red light to inform the operator 82 that a fastening result matching the fastening condition is not obtained.
Then, the server 6 records the fastening result including the erroneous determination (S213). The fastening result is recorded in the log information table 70-1 (S214), and the process is completed.
The recording information can be output and stored in the external memory 50. Further, the server 6 can cause the monitor 24 to display the log information table 70-2 described above.
< treatment from preparation for fastening to execution of fastening >
Fig. 12 shows the process from the fastening preparation to the fastening implementation. Before the flange is fastened, the operator information 64 is acquired from the operator tag 84 (S301), then the flange information 60 is acquired from the flange tag 30 (S302), then the gasket information 62 is acquired from the gasket tag 32 (S303), and then the comparison and determination between the gasket information included in the flange information 60 and the gasket information indicating the actual gasket 12 are performed (S304). In the comparison and determination (S304), a determination is made as to whether or not the gasket 12 is matched with the flange 10 (S305). Thereby, it is determined whether or not the selected spacer 12 is matched with the flange 10 as the fastening object.
If the gasket 12 does not match the flange 10 (no at S305), a red light or the like is turned on as a notification of an erroneous determination (S306), and the process returns to S303. That is, the illumination with the red light informs the operator that the gasket 12 is not matched, thereby prompting the operator to replace the gasket 12.
If the shim 12 is newly selected, the shim information 62 is acquired from the shim label 32 on the shim 12 (S303), and then the comparison and determination are performed again (S304). As a result, if the gasket 12 is matched with the flange 10 (yes in S305), the green light is turned on as a notification of the determination being appropriate (S307), and the fastening condition can be selected (S308). That is, if the green light is not lit, the selection of the fastening condition is prevented.
In selecting the tightening condition, the tightening condition table 68 in the storage unit 44 is referred to, and the tightening condition number is selected from the tightening condition table 68 (S308).
After the fastening condition number is selected, fastening is performed (S309). This tightening is performed by the operator 82 by means of the tightening tool 18.
< processing from fastening to output of log information >
Fig. 13 shows a processing procedure from the fastening to the output of log information. The fastening result is acquired from the sensor 4 (S401), and the fastening result is temporarily stored in the temporary storage area 44-1 of the storage unit 44. The fastening result includes the detected axial force F of the strain gauge 74. A log information table 70-1 is generated based on the fastening result.
The fastening condition is determined with reference to the fastening condition number X of the fastening condition table 68 with respect to the fastening result (S402). In this determination, it is determined whether or not the fastening result matches the fastening condition (S403).
If the fastening result matches the fastening condition (yes at S403), a green light is turned on as a notification of the determination being appropriate (S404), and if the fastening result does not match the fastening condition (no at S403), a red light is turned on as a notification of the erroneous determination (S407).
The log information table 70-1 is generated based on the fastening result, and the log information is collated and processed to generate the log information table 70-2 (S405).
The log information table 70-2 is read into the external memory 50, for example, and is output through the display unit 54 (S406).
< effects of example 1 >
(1) When the flange is fastened, the fastening condition information is read out to the server 6, and it is determined whether or not the fastening result detected by the sensor 4 is appropriate, whereby the reliability of fastening implementation can be improved.
(2) Since the gasket 12 is selected after the flange 10 is selected, and whether or not the gasket information obtained from the gasket 12 matches the gasket information in the flange information is determined by comparing the gasket information with the gasket information, the gasket 12 matching the flange 10 can be selected.
(3) If the pads 12 do not match, the operator can be prompted to replace the pads 12 by making a notification of the warning determination, and the matching pads 12 can be selected.
(4) If it is not checked whether or not the spacers 12 are matched, the shift to the stage of providing the fastening condition is prevented, and the fastening condition is selected after the flange 10 and the spacers 12 are determined, and therefore, the uniform management of the flange 10, the spacers 12, and the fastening condition can be realized.
In the conditions (5) and (4), since the matching fastening condition is automatically selected from the fastening condition information, the operator is not forced to manage the fastening condition, and the burden on the operator from the setting of the fastening condition can be reduced. It is possible to avoid setting the fastening condition depending on the experience and feeling of the operator, to realize automation, and to prevent troublesome work based on written instructions, and input errors or fastening errors due to written instructions. The torque management with high accuracy provided by the fastening condition information can be performed, and the fastening can be efficiently performed according to the axial force F different for each bolt to be fastened. By presenting the fastening result detected by the sensor 4 to the operator, management of flange fastening can be achieved with much higher accuracy than management depending on the personality and feeling of the operator.
(6) Since the flange information is acquired from the flange label 30 attached to the flange 10 and the gasket information is acquired from the gasket label 32 attached to the gasket 12, the reliability of the flange information and the gasket information can be improved and the work for acquiring the respective information can be reduced.
(7) By attaching information codes such as a barcode and a QR (two-dimensional code) (registered trademark) code to the flange label 30 and the gasket label 32, the rapidity and reliability of information acquisition can be improved by using a reading device such as a barcode reader.
(8) In fastening the flange 10, it can be determined whether or not the fastening condition is satisfied. The judgment of the satisfaction of the fastening condition during fastening may include a judgment of the adequacy of a part defect or a work failure such as a fastening defect, a failure of the bolt 14 and the nut 16, a failure occurrence due to fastening, an improper secondary fastening of the same bolt, an error in the fastening order, forgetting to fasten, and the like. Whether or not the fastening result is appropriate (possible/impossible) can be determined from the results of these satisfaction determinations, and recorded as the fastening result in log information. These determinations and recordings are performed simultaneously with the flange fastening, and therefore, a highly reliable work result can be obtained without lowering the work efficiency.
(9) The fastening result containing such information of adequacy or not is supplied from the sensor 4 to the server 6 and recorded. The server 6 can arrange the fastening results, and can extract and edit not only all information but also necessary information to generate log information.
(10) The fastening result information may be stored in the log information tables 70-1 and 70-2 and transmitted from the server 6 to the external memory 50. The log information table 70-2 can be presented by detaching the external memory 50 from the server 6 and attaching it to an external computer.
(11) By expanding the log information table 70-2, the manager can easily know whether or not a fastening result matching the fastening condition is obtained. In the log information table 70-2, as information of adequacy or inadequacy in the fastening result associated with the flange 10, the result of the erroneous determination can be known. The fastening result includes detailed information on the work date and the like associated with the flange 10, and therefore, the details of the work result can be easily known.
(12) Since the operator information is obtained in association with the flange, it is possible to know which operator or construction company is responsible for the operator and the date and time from the work result. The gasket information associated with the flange 10 is judged as appropriate or not before fastening, and therefore, the use of a mismatched gasket can be prevented.
