Description

本発明は、溶接電源装置と、溶接電源装置が行う溶接に関する条件を設定するための溶接条件設定器と、を備えた溶接装置において、溶接電源装置に記憶されている溶接条件の固定あるいは固定の解除を行う、すなわち、溶接条件の変更の可否を行う溶接装置に関する。   The present invention relates to a welding apparatus provided with a welding power supply device and a welding condition setting device for setting conditions relating to welding performed by the welding power supply device, and fixing or fixing welding conditions stored in the welding power supply device. The present invention relates to a welding apparatus that performs release, that is, whether or not to change welding conditions.

アーク溶接を行う場合、溶接対象物であるワークに適した溶接条件を設定する必要がある。多品種少量生産の被溶接物を溶接する場合、ワークが頻繁に変更され、ワークが変更される毎に溶接条件を設定する必要がある。このような場合、溶接作業者が溶接条件設定器を手元に置きながら溶接を行う場合があり、溶接作業者が誤って溶接条件設定器に触れてしまうと、設定している溶接条件が変化してしまう場合がある。   When performing arc welding, it is necessary to set the welding conditions suitable for the workpiece which is the welding object. When welding workpieces of high-mix low-volume production, the workpiece is frequently changed, and it is necessary to set welding conditions each time the workpiece is changed. In such a case, the welding operator may perform welding while placing the welding condition setting device at hand, and if the welding operator accidentally touches the welding condition setting device, the set welding conditions change. May end up.

また、溶接ロボット等を用いた自動の溶接装置を使用する場合、同形状の複数のワークに対して、同一の溶接条件で溶接作業を繰り返し行うことが主となる。この場合、溶接条件を固定して溶接が行われることになる。   Further, when an automatic welding apparatus using a welding robot or the like is used, the welding operation is repeatedly performed on a plurality of workpieces having the same shape under the same welding conditions. In this case, welding is performed with the welding conditions fixed.

また、溶接品質の安定という観点等から、溶接作業者が溶接条件を変更できないようにする、すなわち、溶接条件を固定する場合もある。溶接装置における従来の溶接条件の固定方法としては、溶接装置にキースイッチを設け、キースイッチが入らなければ溶接条件の変更を不許可とするものや、溶接装置にパスワード入力部を設け、パスワードが入力されなければ、溶接条件の変更を不許可とするもの等がある。   Further, from the viewpoint of stable welding quality, etc., the welding operator may not be able to change the welding conditions, that is, the welding conditions may be fixed. As a conventional method for fixing welding conditions in a welding apparatus, a key switch is provided in the welding apparatus, and if the key switch is not turned on, the welding condition is not allowed to be changed. If it is not input, there are things that do not permit the change of welding conditions.

図４は、従来の溶接装置１の概略構成を示す図である。図４において、溶接装置１は、溶接条件を設定するための溶接条件設定器２と、溶接条件設定器２と接続され溶接出力を行うための溶接電源装置３を備えている。溶接電源装置３には、所定の位置に、溶接条件の固定または固定の解除、すわわち、溶接条件の変更の不許可または許可を設定するためのキースイッチ１９が設けられている。   FIG. 4 is a diagram showing a schematic configuration of a conventional welding apparatus 1. In FIG. 4, the welding apparatus 1 includes a welding condition setting device 2 for setting welding conditions, and a welding power supply device 3 connected to the welding condition setting device 2 for performing welding output. The welding power supply device 3 is provided with a key switch 19 at a predetermined position for setting the welding condition to be fixed or released, that is, setting the disapproval or permission to change the welding condition.

次に、図４を用いて、溶接装置１００の動作について説明する。溶接電源装置３は、単相または３相の商用電源１５から電力を入力し、電力変換部１６においてインバータ制御等の出力制御を行い、出力は、溶接に適した溶接電圧や溶接電流に変換して出力する。溶接電流は、溶接電流検出部１７により検出され、溶接電流検出信号が溶接制御部１４に出力される。また、溶接電圧は、溶接電圧検出部１８により検出され、溶接電圧検出信号が溶接制御部１４に出力される。溶接制御部１４は、溶接電流検出信号と、溶接電圧検出信号と、後述する溶接条件設定信号に基づいて、溶接出力の制御に必要な溶接制御信号を生成し、この溶接制御信号を電力変換部１６に出力する。電力変換部１６は、溶接制御信号を入力し、設定された溶接条件に適した溶接出力となるように溶接出力の制御を行う。   Next, operation | movement of the welding apparatus 100 is demonstrated using FIG. The welding power source device 3 receives electric power from a single-phase or three-phase commercial power source 15 and performs output control such as inverter control in the power conversion unit 16, and the output is converted into a welding voltage and welding current suitable for welding. Output. The welding current is detected by the welding current detection unit 17, and a welding current detection signal is output to the welding control unit 14. Further, the welding voltage is detected by the welding voltage detection unit 18, and a welding voltage detection signal is output to the welding control unit 14. The welding control unit 14 generates a welding control signal necessary for controlling the welding output based on a welding current detection signal, a welding voltage detection signal, and a welding condition setting signal described later, and uses the welding control signal as a power conversion unit. 16 is output. The power conversion unit 16 inputs a welding control signal and controls the welding output so that the welding output is suitable for the set welding conditions.

次に、溶接条件の設定方法について説明する。溶接条件の設定時は、キースイッチ１９により、溶接条件の固定を解除した状態としておく。溶接条件設定器２の溶接電流設定部６は、溶接電流設定値を設定するためのものである。設定された溶接電流設定値を示す溶接電流設定信号は、溶接電源装置３の溶接条件記憶部１３に出力される。溶接電圧設定部７は、溶接電圧設定値を設定するためのものである。設定された溶接電圧設定値を示す溶接電圧設定信号は、溶接電源装置３の溶接条件記憶部１３に出力される。また、溶接電源装置３の溶接法設定部１０により、ＣＯ２溶接（炭酸ガスアーク溶接）やＭＡＧ溶接等の溶接法を設定し、溶接法設定信号が溶接条件記憶部１３に出力される。また、溶接電源装置３の一元・個別設定部１１により、一元または個別を設定し、一元・個別設定信号が溶接条件記憶部１３に出力される。また、溶接電源装置３のワイヤ設定部１２により、ソリッドワイヤやフラックスコアードワイヤ等のワイヤ種類やワイヤ径等を設定し、ワイヤ設定信号が溶接条件記憶部１３に出力される。溶接条件記憶部１３は、溶接法設定信号と、一元・個別設定信号と、ワイヤ設定信号と、溶接電流設定信号と、溶接電圧設定信号等に基づいて溶接条件を生成し、溶接条件設定信号として溶接制御部１４に出力する。   Next, a method for setting welding conditions will be described. At the time of setting the welding conditions, the key switch 19 is used to release the fixing of the welding conditions. The welding current setting unit 6 of the welding condition setting device 2 is for setting a welding current set value. A welding current setting signal indicating the set welding current setting value is output to the welding condition storage unit 13 of the welding power source device 3. The welding voltage setting unit 7 is for setting a welding voltage setting value. A welding voltage setting signal indicating the set welding voltage setting value is output to the welding condition storage unit 13 of the welding power source device 3. Further, the welding method setting unit 10 of the welding power source device 3 sets a welding method such as CO2 welding (carbon dioxide arc welding) or MAG welding, and a welding method setting signal is output to the welding condition storage unit 13. Further, the unitary / individual setting unit 11 of the welding power source device 3 sets unitary or individual, and a unitary / individual setting signal is output to the welding condition storage unit 13. In addition, the wire setting unit 12 of the welding power supply device 3 sets the wire type, wire diameter, etc., such as a solid wire and a flux cored wire, and a wire setting signal is output to the welding condition storage unit 13. The welding condition storage unit 13 generates welding conditions based on a welding method setting signal, a unitary / individual setting signal, a wire setting signal, a welding current setting signal, a welding voltage setting signal, and the like, and serves as a welding condition setting signal. Output to the welding control unit 14.

ここで、溶接電源装置３のキースイッチ１９は、鍵（キー）が挿入された状態で回すスイッチである。キースイッチ１９を条件固定の位置とすることで、キースイッチ指令信号が溶接条件記憶部１３に出力され、キースイッチ１９により溶接条件が固定された状態となる。キースイッチ１９により溶接条件を固定状態とした後、キースイッチ１９の鍵を抜くことで、キースイッチ１９の操作ができなくなり、溶接条件の固定解除が不可能となる。そして、キースイッチ１９により溶接条件を固定状態としている場合、溶接条件記憶部１３は、溶接条件を変更するための全ての入力を受け付けなくなり、溶接条件の変更が不許可となる。なお、キースイッチ１９に鍵を差し込んで回し、溶接条件の固定を解除する位置にすると、キースイッチ指令信号の出力が停止され、キースイッチ１９が溶接条件固定解除の状態となる。   Here, the key switch 19 of the welding power source device 3 is a switch that is turned in a state in which a key is inserted. By setting the key switch 19 to a fixed position, a key switch command signal is output to the welding condition storage unit 13 and the welding condition is fixed by the key switch 19. After the welding conditions are fixed by the key switch 19, the key switch 19 cannot be operated by removing the key of the key switch 19, and the welding condition cannot be released. When the welding condition is fixed by the key switch 19, the welding condition storage unit 13 does not accept all inputs for changing the welding condition, and the change of the welding condition is not permitted. When a key is inserted into the key switch 19 and turned to a position where the fixing of the welding condition is released, the output of the key switch command signal is stopped, and the key switch 19 enters a state where the fixing of the welding condition is released.

このように、従来の溶接装置１００として、キースイッチ１９の切り替えにより、溶接作業者に対して一時的に溶接条件の変更を不許可とし、また、キースイッチ１９の鍵を抜くことで、溶接作業者の溶接条件変更を禁止するというものが知られている（例えば、特許文献１参照）。   As described above, as the conventional welding apparatus 100, by switching the key switch 19, the welding operator is temporarily disallowed to change the welding conditions, and the key switch 19 is unlocked to remove the welding operation. It is known that the change of welding conditions of a person is prohibited (see, for example, Patent Document 1).

しかし、従来のキースイッチ１９による溶接条件の固定を行う場合、キースイッチ１９自体が高価であることや、複数の溶接装置１００を所有するユーザの場合には複数のキーを管理する必要が生じて面倒となる等の課題がある。   However, when fixing the welding conditions using the conventional key switch 19, the key switch 19 itself is expensive, and in the case of a user who owns a plurality of welding apparatuses 100, it is necessary to manage a plurality of keys. There are problems such as being troublesome.

また、パスワードにより溶接条件の固定を行う場合、溶接電源装置３にパスワードの設定部や表示部等を設ける必要があり、ユーザインターフェースが複雑になるといった課題がある。   Moreover, when fixing welding conditions with a password, it is necessary to provide the setting part of a password, a display part, etc. in the welding power supply device 3, and there exists a subject that a user interface becomes complicated.

Is output to the welding condition storage unit 13. In addition, the detection of the connection of the welding condition setting device 2 and the welding power supply device 3 is performed by detecting whether or not the welding condition setting device 2 and the welding power supply device 3 are electrically connected, for example.

第２の溶接条件設定部９は、溶接法設定部１０と、一元・個別設定部１１と、ワイヤ設定部１２と、を備えている。ここで、溶接法設定部１０は、溶接法を設定するためのものである。一元・個別設定部１１は、ＣＯ２溶接やＭＡＧ溶接等の溶接法設定信号を溶接条件記憶部１３に出力すると、溶接条件の一元または個別を設定するためのものであり、一元・個別選択信号を溶接条件記憶部１３に出力する。ワイヤ設定部１２は、ソリッドワイヤやフラックスコアードワイヤ等のワイヤ種類やワイヤ径を設定するためのものであり、ワイヤ設定信号を溶接条件記憶部１３に出力する。   The second welding condition setting unit 9 includes a welding method setting unit 10, a unitary / individual setting unit 11, and a wire setting unit 12.

Output to the welding control unit 14.

以上のように構成された溶接装置１について、その動作を説明する。   The operation | movement is demonstrated about the welding apparatus 1 comprised as mentioned above.

先ず、溶接条件設定器２が溶接電源装置３に接続されており、溶接条件変更可否設定部５により溶接条件の変更が可に設定されている場合について説明する。   First, the case where the welding condition setting device 2 is connected to the welding power source device 3 and the welding condition change enable / disable setting unit 5 is set to allow the change of the welding condition will be described.

溶接条件設定器２を溶接電源装置３に装着した場合、すなわち、溶接条件設定器２が溶接電源装置３に接続された場合、接続検出部８から出力された接続検出信号が溶接条件記憶部１３に入力される。これにより、溶接条件設定器２と溶接電源装置３が接続状態であることを溶接条件記憶部１３が認識する。すなわち、接続状態であることを溶接電源装置３が認識する。そして、溶接条件設定器２の溶接条件変更可否設定部５により溶接条件変更を可に設定している場合を考える。この場合には、溶接条件設定器２の第１の溶接条件設定部４および溶接電源装置３の第２の溶接条件設定部９の少なくともいずれかにより、溶接条件記憶部１３に記憶されている溶接条件の変更が許可される状態となっている。そのため、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかにより溶接条件を変更すると、変更された溶接条件は有効となる。そして、溶接条件記憶部１３は、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかにより変更された変更内容を逐次溶接条件記憶部１３に記憶していく。   When the welding condition setting device 2 is attached to the welding power source device 3, that is, when the welding condition setting device 2 is connected to the welding power source device 3, the connection detection signal output from the connection detection unit 8 is the welding condition storage unit 13. Is input. Thereby, the welding condition memory | storage part 13 recognizes that the welding condition setting device 2 and the welding power supply device 3 are a connection state. That is, the welding power supply device 3 recognizes that it is in a connected state. Consider a case where the welding condition change enable / disable setting unit 5 of the welding condition setter 2 sets the welding condition change to be possible. In this case, the welding condition stored in the welding condition storage unit 13 by at least one of the first welding condition setting unit 4 of the welding condition setting device 2 and the second welding condition setting unit 9 of the welding power source device 3. Condition change is permitted. Therefore, if the welding condition is changed by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9, the changed welding condition becomes effective. And the welding condition memory | storage part 13 memorize | stores the changed content changed by at least any one of the 1st welding condition setting part 4 and the 2nd welding condition setting part 9 in the welding condition memory | storage part 13 sequentially.

このように、溶接条件設定器２が溶接電源装置３に接続されており、溶接条件変更可否設定部５により溶接条件の変更が可に設定されている場合、溶接作業者による溶接条件の変更を行うことができる。   As described above, when the welding condition setting device 2 is connected to the welding power source device 3 and the welding condition change enable / disable setting unit 5 sets the welding condition to be changeable, the welding operator can change the welding condition. It can be carried out.

このように変更された溶接条件は、溶接条件記憶部１３に記憶され、図1に示す溶接装置１が溶接を行う時には、溶接条件記憶部１３で記憶された溶接条件で溶接が行われる。すなわち、溶接制御部１４は、溶接出力についての溶接電流および溶接電圧の情報を溶接電流検出部１７および溶接電圧検出部１８から取得し、上述の溶接条件に基づいて所定の溶接出力となるように電力変換部１６を制御して、溶接出力部２０から所定の溶接出力を出力する。   The welding conditions changed in this way are stored in the welding condition storage unit 13, and when the welding apparatus 1 shown in FIG. 1 performs welding, welding is performed under the welding conditions stored in the welding condition storage unit 13. That is, the welding control unit 14 acquires the welding current and welding voltage information regarding the welding output from the welding current detection unit 17 and the welding voltage detection unit 18 so as to obtain a predetermined welding output based on the above-described welding conditions. The power conversion unit 16 is controlled to output a predetermined welding output from the welding output unit 20.

なお、溶接条件変更可否設定部５は、例えば、押しボタンスイッチやトグルスイッチのような安価な部材で構成されている。そして、押しボタンスイッチの場合、例えば押下を繰り返すことで、溶接条件の変更の可と不可の設定が切り替わる。また、トグルスイッチの場合、例えばレバーを倒す方向を変更することにより、溶接条件の変更の可と不可の設定が切り替わる。   In addition, the welding condition change possibility setting part 5 is comprised with cheap members, such as a pushbutton switch and a toggle switch, for example. In the case of a push button switch, for example, the setting of whether or not the welding condition can be changed is switched by repeatedly pressing the button. Further, in the case of a toggle switch, for example, by changing the direction in which the lever is tilted, the setting of whether or not the welding condition can be changed is switched.

次に、溶接条件設定器２が溶接電源装置３に接続されており、溶接条件設定器２の溶接条件変更可否設定部５により、溶接条件変更が不可に設定されている場合について説明する。   Next, the case where the welding condition setting device 2 is connected to the welding power source device 3 and the welding condition change permission setting unit 5 of the welding condition setting device 2 is set to disable the welding condition change will be described.

溶接条件設定器２を溶接電源装置３に装着した場合、すなわち、溶接条件設定器２が溶接電源装置３に電気的に接続された場合、接続検出部８から出力された接続検出信号が溶接条件記憶部１３に入力される。これにより、溶接条件設定器２が溶接電源装置３に接続されている状態であることを溶接電源装置３が認識する。そして、溶接条件変更可否設定部５により溶接条件の変更が不可に設定されている場合、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる、溶接条件記憶部１３に記憶されている溶接条件の変更を不可とする状態になっている。そのため、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる溶接条件の変更内容は無効となる。溶接条件記憶部１３は、溶接条件記憶信号を保持し、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかにより溶接条件の変更を行おうとしても、溶接条件の変更は許可されず、溶接条件の変更は行われない。   When the welding condition setting device 2 is attached to the welding power source device 3, that is, when the welding condition setting device 2 is electrically connected to the welding power source device 3, the connection detection signal output from the connection detection unit 8 is the welding condition. Input to the storage unit 13. Thereby, the welding power supply device 3 recognizes that the welding condition setting device 2 is connected to the welding power supply device 3. When the welding condition change enable / disable setting unit 5 is set so that the welding condition cannot be changed, the welding condition storage unit by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9 is used. 13 is in a state in which the welding conditions stored in 13 cannot be changed. For this reason, changes in the welding conditions by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9 are invalid. The welding condition storage unit 13 holds a welding condition storage signal, and even if the welding condition is changed by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9, Changes are not allowed and welding conditions are not changed.

この場合は、一時的に溶接条件を固定、すなわち、変更不可とした状態に相当する。そして、溶接条件設定器２が溶接電源装置３に接続されており、溶接条件設定器２の溶接条件変更可否設定部５により溶接条件変更が不可に設定されている場合、溶接作業者による溶接条件の変更が不可となっている。   This case corresponds to a state in which the welding conditions are temporarily fixed, that is, cannot be changed. When the welding condition setting device 2 is connected to the welding power source device 3 and the welding condition change enable / disable setting unit 5 of the welding condition setting device 2 is set to disable the welding condition change, the welding condition by the welding operator is set. Cannot be changed.

なお、溶接条件の固定解除は、溶接条件変更可否設定部５により、溶接条件の変更が不可の状態から溶接条件の変更が可の状態へ変更することで対応可能となる。溶接条件変更可否設定部５が例えば押しボタンスイッチである場合、溶接条件の変更が不可の状態から、押しボタンスイッチを押下することにより、溶接条件の変更が可の状態に切り替わる。   The welding condition can be released by changing the welding condition change enable / disable setting unit 5 from a state where the welding condition cannot be changed to a state where the welding condition can be changed. When the welding condition change enable / disable setting unit 5 is a push button switch, for example, the welding condition can be changed from a state where the welding condition cannot be changed to a state where the welding condition can be changed by pressing the push button switch.

次に、溶接条件設定器２を溶接電源装置３から分離している場合、すなわち、溶接条件設定器２が溶接電源装置３に接続されていない場合について説明する。   Next, the case where the welding condition setting device 2 is separated from the welding power source device 3, that is, the case where the welding condition setting device 2 is not connected to the welding power source device 3 will be described.

溶接条件設定器２を溶接電源装置３から分離している場合、溶接条件設定器２を溶接電源装置３に接続していることを示す接続検出信号が接続検出部８から溶接条件記憶部１３に入力されない。そのため、溶接条件設定器２が溶接電源装置３から分離されている状態であることを溶接条件記憶部１３が認識する。すなわち、溶接条件記憶部１３を有する溶接電源装置３が認識する。この場合、溶接条件記憶部１３は、溶接電源装置３に設けられている第２の溶接条件設定部９による溶接条件記憶部１３に記憶されている溶接条件の変更を不可とする。そのため、第２の溶接条件設定部９による溶接条件の変更内容は無効となり、溶接条件記憶部１３は溶接条件記憶信号を保持し、溶接条件の変更は行われない。   When the welding condition setting device 2 is separated from the welding power supply device 3, a connection detection signal indicating that the welding condition setting device 2 is connected to the welding power supply device 3 is sent from the connection detection unit 8 to the welding condition storage unit 13. Not entered. Therefore, the welding condition storage unit 13 recognizes that the welding condition setting device 2 is separated from the welding power source device 3. That is, the welding power supply device 3 having the welding condition storage unit 13 recognizes it. In this case, the welding condition storage unit 13 makes it impossible to change the welding conditions stored in the welding condition storage unit 13 by the second welding condition setting unit 9 provided in the welding power source device 3. Therefore, the change contents of the welding condition by the second welding condition setting unit 9 become invalid, the welding condition storage unit 13 holds the welding condition storage signal, and the welding condition is not changed.

実施の形態１の溶接装置１では、溶接電源装置３から溶接条件設定器２を分離することで、溶接条件設定器２の第１の溶接条件設定部４が溶接電源装置３に接続されなくなる。したがって、第１の溶接条件設定部４は、物理的に溶接装置１に含まれなくなる。このことから、溶接作業者が第１の溶接条件設定部４を用いて溶接条件の変更を行うことができない。   In welding apparatus 1 of the first embodiment, by separating welding condition setting device 2 from welding power supply device 3, first welding condition setting unit 4 of welding condition setting device 2 is not connected to welding power supply device 3. Therefore, the first welding condition setting unit 4 is not physically included in the welding apparatus 1. For this reason, the welding operator cannot change the welding conditions using the first welding condition setting unit 4.

なお、溶接電源装置３にも溶接条件の設定や変更を行うための第２の溶接条件設定部９が設けられている。しかし、接続検出部８が、溶接条件設定器２が溶接電源装置３に接続されていないことを示す信号を溶接条件記憶部１３に出力している場合、溶接条件記憶部１３は、第２の溶接条件設定部９から溶接条件を変更する信号が出力されても、溶接条件の変更を行わないようになっている。   The welding power supply device 3 is also provided with a second welding condition setting unit 9 for setting or changing the welding conditions. However, when the connection detection unit 8 outputs a signal indicating that the welding condition setting device 2 is not connected to the welding power source device 3 to the welding condition storage unit 13, the welding condition storage unit 13 Even if a signal for changing the welding condition is output from the welding condition setting unit 9, the welding condition is not changed.

すなわち、溶接条件設定器２が溶接電源装置３に接続されていない場合、溶接電源装置３に設けられた第２の溶接条件設定部９による溶接条件記憶部１３に記憶されている溶接条件の変更は不可である。また、溶接条件設定器２は溶接電源装置３に接続されていないので、溶接条件設定器２に設けられた第１の溶接条件設定部４による溶接条件記憶部１３に記憶されている溶接条件の変更も行うことができない。このように、溶接条件設定器２が溶接電源装置３に接続されていない場合、溶接条件変更可否設定部５の可否の設定に関わらず、溶接条件記憶部１３に記憶されている溶接条件の変更を行うことができないようになっている。   That is, when the welding condition setting device 2 is not connected to the welding power source device 3, the welding condition stored in the welding condition storage unit 13 by the second welding condition setting unit 9 provided in the welding power source device 3 is changed. Is not possible. Further, since the welding condition setting unit 2 is not connected to the welding power source device 3, the welding condition setting unit 4 provided in the welding condition setting unit 2 has the welding condition stored in the welding condition storage unit 13. No changes can be made. As described above, when the welding condition setting device 2 is not connected to the welding power source device 3, the welding condition stored in the welding condition storage unit 13 is changed regardless of the setting of the welding condition changing permission setting unit 5. Can not do.

このように、溶接条件設定器２と溶接電源装置３の電気的な接続がないという状態を認識する信号を検出するだけで、溶接条件の変更を許可したくない場合には溶接条件が変更されることを防ぐことができる。   As described above, the welding condition is changed only when the signal for recognizing the state where there is no electrical connection between the welding condition setting device 2 and the welding power source device 3 is detected and the change of the welding condition is not permitted. Can be prevented.

なお、溶接条件設定器２が溶接電源装置３に接続されていない場合でも、エラーとはならず、溶接を行うことが可能である。従って、溶接装置１は、溶接条件記憶部１３に記憶している溶接条件でのみ溶接することができる状況となる。   Even when the welding condition setting device 2 is not connected to the welding power source device 3, no error occurs and welding can be performed. Accordingly, the welding apparatus 1 can be welded only under the welding conditions stored in the welding condition storage unit 13.

ここで、従来の溶接装置１００は、溶接条件設定器２と溶接電源装置３を接続した状態で溶接を行うことができる仕様となっており、溶接条件設定器２と溶接電源装置３の接続を解除すると、溶接を行うことができない。   Here, the conventional welding apparatus 100 has specifications that allow welding in a state where the welding condition setting device 2 and the welding power supply device 3 are connected, and the welding condition setting device 2 and the welding power supply device 3 are connected. If released, welding cannot be performed.

しかし、実施の形態１の溶接装置１によれば、溶接条件設定器２と溶接電源装置３の接続を解除しても溶接を行うことが可能である。また、溶接条件設定器２と溶接電源装置３の接続を解除することで溶接条件記憶部１３に記憶されている溶接条件の変更を不可とし、溶接条件記憶部１３に記憶されている溶接条件のみで溶接を行うことができる。   However, according to the welding device 1 of the first embodiment, welding can be performed even if the connection between the welding condition setting device 2 and the welding power source device 3 is released. Further, the welding condition stored in the welding condition storage unit 13 cannot be changed by releasing the connection between the welding condition setting unit 2 and the welding power source device 3, and only the welding conditions stored in the welding condition storage unit 13 are used. Can be welded.

このことから、同一溶接条件で溶接を行う場合や、溶接作業者による溶接条件の変更を認めない場合に対応した溶接装置１を実現することができる。   From this, the welding apparatus 1 corresponding to the case where welding is performed under the same welding conditions or the case where no change of the welding conditions is permitted by the welding operator can be realized.

すなわち、本実施の形態１の溶接装置１は、溶接電源装置３と溶接電源装置３が行う溶接に関する条件を設定するための溶接条件設定器２とを備え、溶接条件設定器２は溶接電源装置３に対して着脱可能である。溶接条件設定器２は、溶接電源装置３に対して溶接条件を設定するための第１の溶接条件設定部４を備える。溶接電源装置３は、接続検出部８と、第２の溶接条件設定部９と、溶接条件記憶部１３と、を備える。ここで、接続検出部８は、溶接条件設定器２が溶接電源装置３に接続されているか否かを検出する。第２の溶接条件設定部９は、溶接条件を設定する。溶接条件記憶部１３は、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかで設定された溶接条件を記憶する。溶接条件設定器２および溶接電源装置３の少なくともいずれかは、溶接条件記憶部１３に記憶された溶接条件の変更の可否を設定するための溶接条件変更可否設定部５を備える。溶接電源装置３は、接続検出部８と溶接条件変更可否設定部５の出力に基づいて第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる、溶接条件記憶部１３に記憶された溶接条件の変更の可否を決定する。   That is, the welding apparatus 1 according to the first embodiment includes a welding power supply device 3 and a welding condition setting device 2 for setting conditions relating to welding performed by the welding power supply device 3, and the welding condition setting device 2 is a welding power supply device. 3 is detachable. The welding condition setting device 2 includes a first welding condition setting unit 4 for setting welding conditions for the welding power source device 3. The welding power supply device 3 includes a connection detection unit 8, a second welding condition setting unit 9, and a welding condition storage unit 13. Here, the connection detection unit 8 detects whether or not the welding condition setting device 2 is connected to the welding power source device 3. The second welding condition setting unit 9 sets welding conditions. The welding condition storage unit 13 stores welding conditions set by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9. At least one of the welding condition setting device 2 and the welding power source device 3 includes a welding condition change permission / rejection setting unit 5 for setting whether or not the welding condition stored in the welding condition storage unit 13 can be changed. The welding power source device 3 includes a welding condition storage unit based on at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9 based on outputs from the connection detection unit 8 and the welding condition change permission / inhibition setting unit 5. 13 determines whether or not the welding conditions stored in 13 can be changed.

この構成により、接続検出部８が出力する接続検出信号と、溶接条件変更可否設定部５が出力する溶接条件の変更の可否信号の組み合わせにより、溶接条件の変更の許可または不許可を、簡単かつ安価に実現できる。すなわち、簡単な構造で、かつ安価に、溶接条件の固定および固定解除を行う溶接装置１を実現できる。   With this configuration, permission or non-permission of changing welding conditions can be easily and by combination of a connection detection signal output from the connection detection unit 8 and a welding condition change permission / inhibition signal output from the welding condition change permission / inhibition setting unit 5. It can be realized at low cost. That is, it is possible to realize the welding apparatus 1 that fixes and releases the welding conditions with a simple structure and at a low cost.

そして、溶接条件設定器２を溶接電源装置３に接続した状態で使用する場合、溶接条件変更可否設定部５の設定のみで溶接条件の変更の可否を設定できる。溶接作業者が手元に溶接条件設定器２を置きながら作業を行う場合でも、溶接条件の変更の可否を容易に選択でき、一時的かつ簡易的な溶接条件の固定が可能となる。そして、溶接条件の変更を不可に設定すると、溶接作業者が誤って溶接条件設定器２に触ってしまった場合でも、溶接条件が変更されてしまうことを防ぐことができる。   When the welding condition setting device 2 is used in a state where it is connected to the welding power source device 3, whether or not the welding condition can be changed can be set only by the setting of the welding condition change possibility setting unit 5. Even when the welding operator performs work while placing the welding condition setting device 2 at hand, it is possible to easily select whether or not the welding condition can be changed, and it is possible to temporarily and simply fix the welding condition. If the welding condition change is set to be impossible, it is possible to prevent the welding condition from being changed even if the welding operator accidentally touches the welding condition setting device 2.

また、実施の形態１の溶接装置１によれば、溶接条件設定器２が溶接電源装置３から分離された場合でも、溶接条件記憶部１３に記憶されている溶接条件に基づいて溶接を行うことができる。そのため、溶接電源装置３から溶接条件設定器２を誤って抜いてしまった場合や、溶接条件設定器２と溶接電源装置３との接続線が断線したような場合等でも、溶接条件を保持して溶接を行うことが可能である。これにより、溶接作業の中断や溶接不良を防ぎ、溶接作業の中断や溶接不良による部品ロス等を抑制することができる。   Moreover, according to the welding apparatus 1 of Embodiment 1, even when the welding condition setting device 2 is separated from the welding power source apparatus 3, welding is performed based on the welding conditions stored in the welding condition storage unit 13. Can do. Therefore, even if the welding condition setting device 2 is mistakenly disconnected from the welding power supply device 3 or the connection line between the welding condition setting device 2 and the welding power supply device 3 is disconnected, the welding conditions are maintained. Welding is possible. Thereby, interruption of welding operation and welding failure can be prevented, and loss of parts due to interruption of welding operation or welding failure can be suppressed.

また、溶接条件設定器２を溶接電源装置３から分離した状態でも、溶接条件記憶部１３に記憶された溶接条件で溶接ができる。このことから、溶接電源装置３と同数の溶接条件設定器２を必要とせず、溶接条件設定器２の数を溶接電源装置３の数より少なくすることができ、経済的にも効果が大である。   Further, even when the welding condition setting device 2 is separated from the welding power source device 3, welding can be performed under the welding conditions stored in the welding condition storage unit 13. Accordingly, the same number of welding condition setting devices 2 as the welding power supply devices 3 are not required, and the number of welding condition setting devices 2 can be made smaller than the number of welding power supply devices 3, which is economically effective. is there.

なお、溶接条件設定器２と溶接電源装置３が接続されていない状態から、溶接条件設定器２と溶接電源装置３を接続した場合には、溶接条件変更可否設定部５の設定内容に関わらず、接続検出部８の出力信号に基づいて、溶接条件記憶部１３に記憶されている溶接条件の変更を不可とするようにしてもよい。このようにすることで、溶接条件設定器２を溶接電源装置３に接続した時に誤って溶接条件が変更されることがなく、誤操作を防止することができる。ここで、溶接条件の変更の不可の解除は、溶接条件変更可否設定部５が不可に設定されている場合には、可に設定することにより解除することできる。また、溶接条件変更可否設定部５が可に設定されている場合には、不可に設定した後に可に設定することにより解除することができる。   Note that, when the welding condition setting unit 2 and the welding power source device 3 are connected from a state where the welding condition setting unit 2 and the welding power source device 3 are not connected, regardless of the setting contents of the welding condition change enable / disable setting unit 5. Based on the output signal of the connection detection unit 8, the welding condition stored in the welding condition storage unit 13 may not be changed. By doing in this way, when the welding condition setting device 2 is connected to the welding power source device 3, the welding conditions are not changed by mistake, and erroneous operation can be prevented. Here, the cancellation of the disabling of changing the welding conditions can be canceled by setting the welding conditions to be possible when the welding condition change permission setting unit 5 is disabled. Moreover, when the welding condition change possibility setting part 5 is set to enable, it can cancel | release by setting it possible after setting it impossible.

なお、溶接装置１の溶接電源装置３は、図示しないブレーカ等の起動スイッチを備える。溶接電源装置３の起動時には、溶接条件変更可否設定部５の設定内容に関わらず、起動スイッチの出力信号に基づいて、溶接条件記憶部１３に記憶されている溶接条件の変更を不可とするようにしてもよい。ここで、記憶されている溶接条件は、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかにより記憶されたものである。   In addition, the welding power supply device 3 of the welding apparatus 1 includes an activation switch such as a breaker (not shown). Regardless of the setting contents of the welding condition change enable / disable setting unit 5 when starting the welding power supply device 3, the welding conditions stored in the welding condition storage unit 13 cannot be changed based on the output signal of the start switch. It may be. Here, the stored welding conditions are those stored by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9.

このようにすることで、溶接装置１の起動時に溶接作業者が無意識に溶接条件設定器２に当たってしまう等して溶接条件が変更される等の誤操作を防止することができる。ここで、溶接条件の変更の不可の解除は、溶接条件変更可否設定部５が不可に設定されている場合には、可に設定することにより解除することできる。また、溶接条件変更可否設定部５が可に設定されている場合には、不可に設定した後に可に設定することにより解除することができる。   By doing so, it is possible to prevent an erroneous operation such as a welding condition being changed when the welding operator unintentionally hits the welding condition setting device 2 when the welding apparatus 1 is activated. Here, the cancellation of the disabling of changing the welding conditions can be canceled by setting the welding conditions to be possible when the welding condition change permission setting unit 5 is disabled. Moreover, when the welding condition change possibility setting part 5 is set to enable, it can cancel | release by setting it possible after setting it impossible.

なお、溶接条件変更可否設定部５は、図１に示すように溶接条件設定器２のみに設けるようにしてもよいし、図２に示すように溶接電源装置３のみに設けるようにしてもよい。また、図３に示すように溶接条件設定器２と溶接電源装置３の両方に設けるようにしてもよい。図１の溶接装置１、図２の溶接装置２１および図３の溶接装置３１は、溶接条件変更可否設定部５が設けられた位置や個数が異なるだけで、溶接装置としての機能や基本的な動作は同じである。   The welding condition change permission / inhibition setting unit 5 may be provided only in the welding condition setting device 2 as shown in FIG. 1, or may be provided only in the welding power source device 3 as shown in FIG. . Moreover, as shown in FIG. 3, you may make it provide in both the welding condition setting device 2 and the welding power supply device 3. FIG. The welding apparatus 1 in FIG. 1, the welding apparatus 21 in FIG. 2, and the welding apparatus 31 in FIG. 3 differ only in the position and number of the welding condition change enable / disable setting unit 5, and the functions and basics of the welding apparatus are the same. The operation is the same.

なお、溶接条件設定器２に設けられた第１の溶接条件設定部４および溶接電源装置３に設けられた第２の溶接条件設定部９にある各設定部は、第１の溶接条件設定部４と第２の溶接条件設定部９のどちらにあってもよい。但し、少なくとも１つの設定部は、溶接電源装置３に設けられた第２の溶接条件設定部９に設けるようにしてもよい。   In addition, each setting part in the 1st welding condition setting part 4 provided in the welding condition setting device 2 and the 2nd welding condition setting part 9 provided in the welding power supply device 3 is a 1st welding condition setting part. 4 and the second welding condition setting unit 9 may be present. However, at least one setting unit may be provided in the second welding condition setting unit 9 provided in the welding power source device 3.

例えば、溶接条件設定器２に設けられた第１の溶接条件設定部４は、図１から図３に示すように溶接電流と溶接電圧を設定する機能を有し、溶接電源装置３に設けられた第２の溶接条件設定部９は、溶接電流と溶接電圧を除く溶接条件を設定する機能を有するようにしてもよい。このような構成により、溶接条件設定器２の機能を絞ることで溶接条件設定器２の小型化が図れ、溶接作業者が溶接条件設定器２を持って運ぶ際の利便性を高めることができる。   For example, the first welding condition setting unit 4 provided in the welding condition setting device 2 has a function of setting a welding current and a welding voltage as shown in FIGS. 1 to 3, and is provided in the welding power supply device 3. Further, the second welding condition setting unit 9 may have a function of setting welding conditions excluding the welding current and the welding voltage. With such a configuration, it is possible to reduce the size of the welding condition setting device 2 by narrowing down the functions of the welding condition setting device 2, and it is possible to improve convenience when the welding operator carries the welding condition setting device 2. .

また、本発明の溶接装置１、２１、３１において、溶接電源装置３は、溶接出力を行う溶接出力部２０と、溶接条件記憶部１３に記憶された溶接条件に基づいて溶接出力部２０を制御する溶接制御部１４を備えている。溶接電源装置３は、溶接条件設定器２が溶接電源装置３から取り外された場合には、溶接条件変更可否設定部５の設定内容に関わらず、溶接条件記憶部１３に記憶されている溶接条件の変更を不可として保持する。また、溶接電源装置３は、溶接条件設定器２が溶接電源装置３から取り外された場合でも、溶接条件記憶部１３に記憶されている溶接条件に基づいて溶接を行う構成としてもよい。   Moreover, in the welding apparatuses 1, 21, and 31 of the present invention, the welding power source apparatus 3 controls the welding output unit 20 based on the welding output unit 20 that performs welding output and the welding conditions stored in the welding condition storage unit 13. A welding control unit 14 is provided. When the welding condition setting device 2 is detached from the welding power supply apparatus 3, the welding power supply device 3 is not connected to the welding condition change enable / disable setting unit 5, but is stored in the welding condition storage unit 13. Keep the change as impossible. Further, the welding power supply device 3 may be configured to perform welding based on the welding conditions stored in the welding condition storage unit 13 even when the welding condition setting device 2 is detached from the welding power supply device 3.

この構成により、溶接条件が変更されることを防ぐと共に、溶接が中断されることなく記憶されている溶接条件で溶接を行うことができる。   With this configuration, the welding conditions can be prevented from being changed, and welding can be performed under the stored welding conditions without being interrupted.

また、溶接条件設定器２が溶接電源装置３に接続されており、かつ、溶接条件変更可否設定部５が溶接条件の変更可に設定されている場合を考える。この場合には、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる、溶接条件記憶部１３に記憶されている溶接条件の変更を可とする。また、溶接条件設定器２が溶接電源装置３に接続されており、かつ、溶接条件変更可否設定部５が溶接条件の変更不可に設定されている場合を考える。この場合には、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる、溶接条件記憶部１３に記憶されている溶接条件の変更を不可とする。また、溶接条件設定器２が溶接電源装置３に接続されていない場合には、第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる、溶接条件記憶部１３に記憶されている溶接条件の変更を不可とする構成としてもよい。   Further, consider the case where the welding condition setting device 2 is connected to the welding power source device 3 and the welding condition change enable / disable setting unit 5 is set to change the welding condition. In this case, the welding conditions stored in the welding condition storage unit 13 can be changed by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9. Further, consider a case where the welding condition setting device 2 is connected to the welding power source device 3 and the welding condition change enable / disable setting unit 5 is set so that the welding condition cannot be changed. In this case, the welding conditions stored in the welding condition storage unit 13 cannot be changed by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9. Further, when the welding condition setting device 2 is not connected to the welding power source device 3, the welding condition storage unit 13 by at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9 is used. The stored welding conditions may not be changed.

この構成により、接続検出部８と溶接条件変更可否設定部５の出力に基づいて第１の溶接条件設定部４および第２の溶接条件設定部９の少なくともいずれかによる溶接条件記憶部１３に記憶された溶接条件の変更の可否を決定することができる。また、溶接条件の変更の不可を設定することで、溶接条件の変更を許可したくない場合には溶接条件が変更されることを防ぐことができる。このことにより、簡単な構造で、かつ安価に、溶接条件の固定および固定解除を行う溶接装置を実現することができる。   With this configuration, the welding condition storage unit 13 stores at least one of the first welding condition setting unit 4 and the second welding condition setting unit 9 based on the outputs of the connection detection unit 8 and the welding condition change permission / inhibition setting unit 5. It is possible to determine whether or not the changed welding conditions can be changed. In addition, by setting the change of the welding condition to be impossible, it is possible to prevent the welding condition from being changed when it is not desired to allow the change of the welding condition. As a result, it is possible to realize a welding apparatus that fixes and releases the welding conditions with a simple structure and at low cost.
