［溶接実績自動採取方法］
ここで、本実施形態の溶接実績自動採取システム１０による溶接実績自動採取方法について説明する。図２および図３は、本実施形態の溶接実績自動採取方法を表すフローチャート、図４は、溶接電圧値の変化を表すグラフである。 [Welding record automatic collection method]
Here, a welding record automatic sampling method by the welding record automatic sampling system 10 of the present embodiment will be described. 2 and 3 are flowcharts showing the welding results automatic sampling method of the present embodiment, and FIG. 4 is a graph showing changes in welding voltage values.

本実施形態の溶接実績自動採取方法は、溶接実績自動採取装置１２に溶接電源情報を計測可能な計測器１１を接続する工程と、溶接実績自動採取装置１２に溶接管理システム３０から溶接準備情報を取り込む工程と、溶接実績自動採取装置１２に溶接電源情報を取り込む工程と、溶接電源情報に基づいて溶接実績自動採取装置１２に溶接機制御装置２３から溶接実績情報を取得する工程と、溶接準備情報と溶接実績情報とを関連付ける工程とを有する。 The welding record automatic sampling method of the present embodiment includes a step of connecting a measuring instrument 11 capable of measuring welding power supply information to the welding record automatic sampling device 12, and welding preparation information from the welding management system 30 to the welding record automatic sampling device 12. The process of importing welding record information into the welding record automatic sampling device 12, the process of acquiring welding record information from the welding machine control device 23 to the welding record automatic sampling device 12 based on the welding power source information, and welding preparation information. It has a process of associating with welding record information.

ここで、溶接実績自動採取装置１２は、計測器１１の接続状態が確認されると、計測器１１が計測した溶接電源情報の取得を開始する。溶接実績自動採取装置１２は、溶接電圧値が０Ｖを超えてから予め設定された第１所定時間（例えば、５秒）が経過した後に、計測器１１が計測した溶接電源情報に基づいて溶接実績情報を取得する。一方、溶接実績自動採取装置１２は、溶接電圧値が０Ｖになると計測器１１による溶接電源情報の計測を停止する。そのため、溶接実績自動採取装置１２は、第１所定時間から予め設定された第２所定時間（例えば、５秒）までに計測器１１が計測した溶接電源情報に基づいて溶接実績情報を取得する。なお、第２所定時間は、溶接電圧値が０Ｖになってから第３所定時間（例えば、５秒）遡った時間であるが、第２所定時間が、例えば、５秒よりも短いとき、計測した溶接電源情報を破棄する。 Here, when the connection state of the measuring instrument 11 is confirmed, the welding record automatic sampling device 12 starts acquiring the welding power supply information measured by the measuring instrument 11. The welding record automatic sampling device 12 has a welding record based on the welding power supply information measured by the measuring instrument 11 after a preset first predetermined time (for example, 5 seconds) has elapsed after the welding voltage value exceeds 0 V. Get information. On the other hand, the welding record automatic sampling device 12 stops the measurement of welding power supply information by the measuring instrument 11 when the welding voltage value reaches 0V. Therefore, the welding record automatic sampling device 12 acquires welding record information based on the welding power supply information measured by the measuring instrument 11 from the first predetermined time to the preset second predetermined time (for example, 5 seconds). The second predetermined time is a time that goes back to the third predetermined time (for example, 5 seconds) after the welding voltage value becomes 0 V, but is measured when the second predetermined time is shorter than, for example, 5 seconds. Discard the welding power supply information.

また、溶接実績自動採取装置１２は、関連付けられた溶接準備情報と溶接実績情報との関連情報を出力部１４のディスプレイに表示する。溶接実績自動採取装置１２は、計測器１１が計測した複数の溶接電源情報の平均値を溶接実績情報として取得する。この場合、溶接実績自動採取装置１２は、計測器１１が計測した複数の溶接電源情報を溶接管理システム３０に送信し、溶接管理システム３０が複数の溶接電源情報の平均値を算出し、溶接管理システム３０が算出した平均値を溶接実績情報として取得する。なお、溶接実績自動採取装置１２は、計測器１１が計測した溶接電源情報が予め設定された適正範囲にないとき、溶接を停止する。 Further, the welding record automatic sampling device 12 displays the related information between the associated welding preparation information and the welding record information on the display of the output unit 14. The welding record automatic sampling device 12 acquires the average value of a plurality of welding power supply information measured by the measuring instrument 11 as welding record information. In this case, the welding record automatic sampling device 12 transmits a plurality of welding power supply information measured by the measuring instrument 11 to the welding management system 30, and the welding management system 30 calculates an average value of the plurality of welding power supply information to manage welding. The average value calculated by the system 30 is acquired as welding record information. The welding record automatic sampling device 12 stops welding when the welding power supply information measured by the measuring instrument 11 is not within a preset appropriate range.

具体的に説明すると、図１から図３に示すように、ステップＳ１１にて、溶接実績自動採取装置１２は、計測器１１に対して接続状態確認信号を送信する。ステップＳ１２にて、計測器１１は、溶接実績自動採取装置１２からの接続状態確認信号を受信したかどうかを確認する。ここで、計測器１１は、接続状態確認信号を受信しない（Ｎｏ）とき、受信するまで待機する。一方、計測器１１は、接続状態確認信号を受信する（Ｙｅｓ）と、ステップＳ１３にて、溶接実績自動採取装置１２に対して接続状態確認信号を送信する。ステップＳ１４にて、溶接実績自動採取装置１２は、計測器１１からの接続状態確認信号を受信したかどうかを確認する。ここで、溶接実績自動採取装置１２は、接続状態確認信号を受信していない（Ｎｏ）とき、ステップＳ１１に戻る。一方、溶接実績自動採取装置１２は、接続状態確認信号を受信する（Ｙｅｓ）と、ステップＳ１５にて、接続状態確認信号を受信した計測器１１を割り当てる。すなわち、溶接実績自動採取装置１２は、複数の溶接機制御装置２３が接続されおり、接続状態確認信号を送受信した受信信号に対して計測器１１を割り当てる。 Specifically, as shown in FIGS. 1 to 3, in step S11, the welding record automatic sampling device 12 transmits a connection state confirmation signal to the measuring instrument 11. In step S12, the measuring instrument 11 confirms whether or not the connection status confirmation signal from the welding record automatic sampling device 12 has been received. Here, when the measuring instrument 11 does not receive the connection status confirmation signal (No), the measuring instrument 11 waits until it receives the signal. On the other hand, when the measuring instrument 11 receives the connection status confirmation signal (Yes), the measuring instrument 11 transmits the connection status confirmation signal to the welding record automatic sampling device 12 in step S13. In step S14, the welding record automatic sampling device 12 confirms whether or not the connection status confirmation signal from the measuring instrument 11 has been received. Here, when the welding record automatic sampling device 12 has not received the connection status confirmation signal (No), the process returns to step S11. On the other hand, when the welding record automatic sampling device 12 receives the connection status confirmation signal (Yes), the measuring instrument 11 that has received the connection status confirmation signal is assigned in step S15. That is, in the welding record automatic sampling device 12, a plurality of welding machine control devices 23 are connected, and the measuring instrument 11 is assigned to a received signal that transmits and receives a connection state confirmation signal.

ステップＳ１６にて、溶接実績自動採取装置１２は、溶接管理装置３１（溶接管理システム３０）に対して溶接線情報の送信指示を行う。溶接管理装置３１は、ステップＳ１７にて、予め溶接線情報の入力を行い、ステップＳ１８にて、溶接記録書の番号を登録しておく。そして、ステップＳ１９にて、溶接管理装置３１は、溶接実績自動採取装置１２からの溶接線情報の送信指示に対して、溶接実績自動採取装置１２に溶接準備情報を送信する。溶接実績自動採取装置１２は、ステップＳ２０にて、溶接準備情報を受信すると、ステップＳ２１にて、溶接準備情報を確認する。すなわち、溶接実績自動採取装置１２は、受信した溶接準備情報に、必要な情報が揃っているかどうかを確認する。ここで、溶接実績自動採取装置１２は、溶接準備情報に必要な情報が揃っていない（Ｎｏ）とき、ステップ１６に戻る。一方、溶接実績自動採取装置１２は、溶接準備情報に必要な情報が揃っている（Ｙｅｓ）と、ステップＳ２２に移行する。 In step S16, the welding record automatic sampling device 12 instructs the welding management device 31 (welding management system 30) to transmit welding line information. The welding management device 31 inputs the welding line information in advance in step S17, and registers the welding record number in step S18. Then, in step S19, the welding management device 31 transmits the welding preparation information to the welding record automatic sampling device 12 in response to the welding line information transmission instruction from the welding record automatic sampling device 12. When the welding record automatic sampling device 12 receives the welding preparation information in step S20, the welding preparation information is confirmed in step S21. That is, the welding record automatic sampling device 12 confirms whether or not the received welding preparation information includes necessary information. Here, the welding record automatic sampling device 12 returns to step 16 when the necessary information is not available in the welding preparation information (No). On the other hand, when the welding record automatic sampling device 12 has all the necessary information for the welding preparation information (Yes), the process proceeds to step S22.

ステップＳ２２にて、溶接実績自動採取装置１２は、溶接機制御装置２３に対して接続信号を送信する。ステップＳ２３にて、溶接機制御装置２３は、接続信号を受信することで通信状態の確認を行う。すると、ステップＳ２４にて、溶接実績自動採取装置１２は、計測準備完了となる。そして、ステップＳ２５にて、溶接機制御装置２３は、溶接機２１を作動して溶接を開始する。ステップＳ２６にて、溶接機制御装置２３は、溶接実績自動採取装置１２との通信状態が良好かどうかを確認する。ここで、溶接機制御装置２３と溶接実績自動採取装置１２との通信状態が良好でない（Ｎｏ）とき、溶接機制御装置２３は、ステップＳ２７にて、溶接を停止し、ステップＳ２３に戻る。一方、溶接機制御装置２３と溶接実績自動採取装置１２との通信状態が良好である（Ｙｅｓ）と、ステップＳ２８にて、溶接機制御装置２３は、溶接管理情報を溶接実績自動採取装置１２に送信する。ステップＳ２９では、溶接作業の終了を確認する。すなわち、所定の溶接作業が終了するまで、溶接機制御装置２３と溶接実績自動採取装置１２との通信状態が良好かどうかを確認している。 In step S22, the welding record automatic sampling device 12 transmits a connection signal to the welding machine control device 23. In step S23, the welding machine control device 23 confirms the communication state by receiving the connection signal. Then, in step S24, the welding record automatic sampling device 12 is ready for measurement. Then, in step S25, the welding machine control device 23 operates the welding machine 21 to start welding. In step S26, the welding machine control device 23 confirms whether or not the communication state with the welding record automatic sampling device 12 is good. Here, when the communication state between the welding machine control device 23 and the welding record automatic sampling device 12 is not good (No), the welding machine control device 23 stops welding in step S27 and returns to step S23. On the other hand, when the communication state between the welding machine control device 23 and the welding record automatic sampling device 12 is good (Yes), the welding machine control device 23 transfers the welding management information to the welding record automatic sampling device 12 in step S28. Send. In step S29, the completion of the welding work is confirmed. That is, it is confirmed whether or not the communication state between the welding machine control device 23 and the welding record automatic sampling device 12 is good until the predetermined welding work is completed.

ステップＳ３１にて、計測器１１は、溶接電源情報としての溶接電流値と溶接電圧値を予め設定された所定周期で計測し、溶接実績自動採取装置１２に出力する。ステップＳ３２にて、溶接実績自動採取装置１２は、溶接電圧値Ｖが０Ｖを超えたかどうかを判定する。ここで、溶接電圧値Ｖが０Ｖを超えていないと判定（Ｎｏ）されると、溶接電圧値Ｖが０Ｖを超えるまで待機する。一方、溶接電圧値Ｖが０Ｖを超えたと判定（Ｙｅｓ）されると、ステップＳ３３にて、溶接実績自動採取装置１２は、処理を開始する。すなわち、溶接実績自動採取装置１２は、計測器１１が計測した溶接電圧値と溶接電流値を取得する。 In step S31, the measuring instrument 11 measures the welding current value and the welding voltage value as the welding power supply information at a predetermined predetermined cycle, and outputs the welding results to the welding record automatic sampling device 12. In step S32, the welding record automatic sampling device 12 determines whether or not the welding voltage value V exceeds 0V. Here, if it is determined (No) that the welding voltage value V does not exceed 0V, the process waits until the welding voltage value V exceeds 0V. On the other hand, when it is determined (Yes) that the welding voltage value V exceeds 0V, the welding record automatic sampling device 12 starts the process in step S33. That is, the welding record automatic sampling device 12 acquires the welding voltage value and the welding current value measured by the measuring instrument 11.

その後、ステップＳ２９にて、溶接作業の終了が確認されると、ステップＳ３０にて、溶接作業を停止し、計測器１１が計測した溶接電圧値と溶接電流値が低下する。ステップＳ３４にて、溶接実績自動採取装置１２は、溶接電圧値Ｖが０Ｖになったかどうかを判定する。ここで、溶接電圧値Ｖが０Ｖより大きいと判定（Ｎｏ）されると、溶接電圧値Ｖが０Ｖになるまで待機する。一方、溶接電圧値Ｖが０Ｖになったと判定（Ｙｅｓ）されると、ステップＳ３５にて、溶接実績自動採取装置１２は、処理を終了する。ステップＳ３６にて、溶接実績自動採取装置１２は、溶接時間が予め設定された所定時間（例えば、５秒）以上であるかどうかを判定する。ここで、溶接時間が所定時間以上でないと判定（Ｎｏ）されると、溶接実績自動採取装置１２は、取得した溶接電圧値および溶接電流値を記録せずに終了する。一方、溶接時間が所定時間以上であると判定（Ｙｅｓ）されると、ステップＳ３７にて、溶接実績自動採取装置１２は、取得した溶接電圧値および溶接電流値を溶接管理装置３１に送信する。ステップＳ３８にて、溶接管理装置３１は、全ての溶接電圧値および溶接電流値を取り込み、データを平均化処理し、ステップＳ３９にて、溶接実績情報として溶接実績自動採取装置１２に送信する。また、ステップＳ４０にて、溶接管理装置３１は、平均化処理した溶接実績情報を記録部３４に記録する。溶接実績自動採取装置１２は、ステップＳ４１にて、溶接準備情報と溶接実績情報とを関連付けた関連情報を出力部１４のディスプレイに表示し、ステップＳ４２にて、この関連情報を出力する。 After that, when the completion of the welding work is confirmed in step S29, the welding work is stopped in step S30, and the welding voltage value and the welding current value measured by the measuring instrument 11 decrease. In step S34, the welding record automatic sampling device 12 determines whether or not the welding voltage value V has become 0V. Here, if it is determined (No) that the welding voltage value V is larger than 0V, the process waits until the welding voltage value V becomes 0V. On the other hand, when it is determined (Yes) that the welding voltage value V has reached 0V, the welding record automatic sampling device 12 ends the process in step S35. In step S36, the welding record automatic sampling device 12 determines whether or not the welding time is equal to or longer than a preset predetermined time (for example, 5 seconds). Here, if it is determined (No) that the welding time is not equal to or longer than the predetermined time, the welding record automatic sampling device 12 ends without recording the acquired welding voltage value and welding current value. On the other hand, if it is determined (Yes) that the welding time is equal to or longer than a predetermined time, the welding record automatic sampling device 12 transmits the acquired welding voltage value and welding current value to the welding management device 31 in step S37. In step S38, the welding management device 31 takes in all the welding voltage values and welding current values, averages the data, and in step S39, transmits the welding record information to the welding record automatic sampling device 12. Further, in step S40, the welding management device 31 records the averaged welding record information in the recording unit 34.

ここで、複数の溶接データＤ１を平均化処理して溶接データＤ２を求める方法について説明する。図４に示すように、時間ｔ１にて、溶接が開始されると、電圧値が上昇し、時間ｔ２で一定となる。このとき、溶接開始（電圧値が０Ｖを超えて）から第１所定時間（例えば、５秒）Ｔ１が経過した後、計測器１１が計測した溶接データに基づいて溶接実績を取得する。そして、時間ｔ３にて、溶接を終了すると、電圧値が下降し、時間ｔ４で０Ｖとなる。第１所定時間から第２所定時間（最大１２０秒）を経過するまでに計測器１１が計測した溶接データに基づいて溶接実績を取得する。つまり、電圧値が０Ｖになってから第３所定時間（例えば、５秒）Ｔ３だけ遡った時間である。 Here, a method of averaging a plurality of welding data D1 to obtain welding data D2 will be described. As shown in FIG. 4, when welding is started at time t1, the voltage value rises and becomes constant at time t2. At this time, after the first predetermined time (for example, 5 seconds) T1 has elapsed from the start of welding (the voltage value exceeds 0 V), the welding record is acquired based on the welding data measured by the measuring instrument 11. Then, when the welding is completed at the time t3, the voltage value drops and becomes 0V at the time t4. Welding results are acquired based on the welding data measured by the measuring instrument 11 from the first predetermined time to the second predetermined time (maximum 120 seconds). That is, it is a time that goes back by T3 for a third predetermined time (for example, 5 seconds) after the voltage value becomes 0 V.
