Abstract

The present invention achieves a lower-cost welding machine allowing the operator to easily set welding conditions and determine welding parameters even if the operator does not have much knowledge about welding conditions. This welding machine is provided with functions for determining welding conditions by selecting and determining a plurality of welding-related information items (B, C), wherein instead of using a liquid-crystal display unit for display of characters on an operation unit (2), a plurality of LEDs (A1-A3) provided with a plurality of segments are used. By operation of a switching unit (4) and a determination unit (5), illumination of the LED segments is switched according to specific welding-related information, allowing the operator to input welding conditions. When input of all the welding conditions is complete, the optimal welding parameters for the input welding conditions are determined and displayed.

Description

溶接機Welding machine
　本発明は、例えばアークを発生させて加工対象物を加工する装置、特にデジタル制御を行う溶接機に関する。 The present invention relates to an apparatus for processing a workpiece by generating an arc, for example, and more particularly to a welding machine that performs digital control.
　近年、機器の高性能化や高機能化に対応するため、溶接機の電力制御回路、ガス制御回路およびスタート制御回路などの制御回路は、プログラム可能な素子で構成されている。そして、溶接機はソフトウェアで制御されることが一般的となっており、デジタル制御溶接機（以下、「デジタル溶接機」と称する。）として普及している。 In recent years, control circuits such as a power control circuit, a gas control circuit, and a start control circuit of a welding machine are composed of programmable elements in order to cope with higher performance and higher functionality of equipment. The welding machine is generally controlled by software, and is widely used as a digitally controlled welding machine (hereinafter referred to as “digital welding machine”).
　このデジタル溶接機は、複数の溶接方法を備え、各々の溶接方法に対して詳細な条件設定が可能となっている。例えば、溶接方法に関しては、加工対象物が鉄やステンレスの場合に出力を直流出力とする直流溶接モードや、加工対象物がアルミニウムの場合に出力を交流とする交流出力モードがある。また、溶接方法に関しては、加工対象物の状態に応じて出力をパルス波形とするパルス溶接法など、さまざまな溶接方法がある。また、詳細な条件設定に関しては、加工対象物の厚みや溶接姿勢などに応じて出力電流、パルス周波数およびパルス幅などを変化させる必要があり、その条件パラメータは膨大である。 This digital welder has a plurality of welding methods, and detailed conditions can be set for each welding method. For example, regarding the welding method, there are a DC welding mode in which the output is DC output when the workpiece is iron or stainless steel, and an AC output mode in which the output is AC when the workpiece is aluminum. As for the welding method, there are various welding methods such as a pulse welding method in which the output is a pulse waveform according to the state of the workpiece. Further, regarding detailed condition setting, it is necessary to change the output current, the pulse frequency, the pulse width, and the like in accordance with the thickness of the workpiece and the welding posture, and the condition parameters are enormous.
　デジタル溶接機では、これらの多くのパラメータを設定するため、通常、ジョグダイヤルと呼ばれるエンコーダーや、ＬＥＤ表示部、さらには条件設定用の複数のスイッチを備えている。そして、これらのパラメータの設定は、作業者の知識と経験、または、取扱説明書などの施工条件を参考に設定される。 In order to set these many parameters, a digital welder is usually equipped with an encoder called a jog dial, an LED display, and a plurality of switches for setting conditions. These parameters are set with reference to the operator's knowledge and experience or construction conditions such as an instruction manual.
　加えて、最近のアーク溶接機では、操作部に液晶表示部などの文字表示部を備えているものもある。そのアーク溶接機では、液晶表示の指示に従いながら、作業者が加工対象物や溶接姿勢などに対応した溶接の条件を設定する。これにより、アーク溶接機は、その溶接条件に一般的に適切である溶接方法や溶接電流などのパラメータを設定できるような機能を有している。このアーク溶接機を使用することによって、溶接熟練者でなくても、簡単に、作業者の行う溶接条件のパラメータを設定することが可能である（例えば、特許文献１参照）。 In addition, some recent arc welders have a character display section such as a liquid crystal display section in the operation section. In the arc welding machine, an operator sets welding conditions corresponding to a workpiece and a welding posture while following instructions on a liquid crystal display. As a result, the arc welder has a function capable of setting parameters such as a welding method and a welding current that are generally appropriate for the welding conditions. By using this arc welding machine, it is possible to easily set parameters for welding conditions performed by an operator, even if they are not skilled in welding (see, for example, Patent Document 1).
　以下、従来の溶接機について、図１４を参照しながら説明する。図１４は、従来の溶接機の操作部の概略構成を示す平面図である。 Hereinafter, a conventional welding machine will be described with reference to FIG. FIG. 14 is a plan view showing a schematic configuration of an operation unit of a conventional welding machine.
　図１４に示すように、アーク溶接機は、操作部に英数字などを表示するためのＬＥＤ表示部２１と、文字情報を表示するための液晶表示部２２と、条件設定用のジョグダイヤル２３と、条件設定用のスイッチ部２４と、を備えている。 As shown in FIG. 14, the arc welding machine includes an LED display unit 21 for displaying alphanumeric characters and the like on the operation unit, a liquid crystal display unit 22 for displaying character information, a jog dial 23 for setting conditions, A switch unit 24 for setting conditions.
　以上のように構成された従来のアーク溶接機について、その動作を説明する。 The operation of the conventional arc welder configured as described above will be described.
　作業者は、スイッチ部２４の操作により、溶接条件の項目を選択し、ジョグダイヤル２３の操作により溶接条件の項目に対する数値を設定する。設定した数値はＬＥＤ表示部２１に表示され、確認することができる。そして、作業者は、この操作を繰り返し行い、目的とする溶接に必要な条件を全て設定し、その後に溶接を開始する。 The operator selects a welding condition item by operating the switch unit 24, and sets a numerical value for the welding condition item by operating the jog dial 23. The set numerical value is displayed on the LED display unit 21 and can be confirmed. And an operator repeats this operation, sets all the conditions required for the target welding, and starts welding after that.
　また、溶接条件を導きだす機能がついている溶接機の場合は、まず作業者がスイッチ部２４で、溶接条件を導き出すモードを選択する。すると、液晶表示部２２の表示が、加工対象物などの条件設定の状態に切り替わる。そこから、作業者は、作業者が行う溶接設定をジョグダイヤル２３とスイッチ部２４を操作しながら決定して入力していく。これにより、最終的にその設定に適した溶接条件がＬＥＤ表示部２１に表示される。 In the case of a welding machine having a function for deriving welding conditions, the operator first selects a mode for deriving the welding conditions using the switch unit 24. Then, the display on the liquid crystal display unit 22 is switched to a condition setting state such as an object to be processed. From there, the operator determines and inputs the welding setting performed by the operator while operating the jog dial 23 and the switch unit 24. Thereby, the welding conditions suitable for the setting are finally displayed on the LED display unit 21.
　しかしながら、従来のアーク溶接機では、複数の溶接関連情報を選択して決定することで溶接条件を決定する機能を備えた溶接機の場合、そのパラメータの多さから、液晶表示や、溶接方法設定用に複数のスイッチなどが必要となってしまい、高価であった。 However, in the conventional arc welder, in the case of a welder having a function of determining welding conditions by selecting and determining a plurality of welding related information, liquid crystal display and setting of welding method are set due to the large number of parameters. For this purpose, a plurality of switches are required, which is expensive.

　次に、本実施の形態１の溶接機１の操作部２について説明する。なお、図３の操作部２の概略構成の平面図を用いて、操作部２の概念的な説明を行い、図４の操作部２の概略構成の平面図を用いて、操作部２の具体例の説明を行う。 Next, the operation unit 2 of the welding machine 1 according to the first embodiment will be described. It should be noted that a conceptual description of the operation unit 2 will be given using the plan view of the schematic configuration of the operation unit 2 in FIG. An example will be explained.
　図３に示すように、操作部２には、英数字などを表示するための複数のセグメントを有するＬＥＤを複数個備えたＬＥＤ表示部３と、ＬＥＤ表示部３の表示内容を切り換えるための切換部４と、決定部５と、モード設定部６と、を備えている。なお、ＬＥＤ表示部３は、複数のＬＥＤ３ａが配置されて、第１のＬＥＤ表示部Ａ１と、第２のＬＥＤ表示部Ａ２と、第３のＬＥＤ表示部Ａ３と、を備え、それぞれにセグメント部を構成している。 As shown in FIG. 3, the operation unit 2 includes an LED display unit 3 including a plurality of LEDs having a plurality of segments for displaying alphanumeric characters, and a switch for switching display contents of the LED display unit 3.

The LED display unit 3 includes a plurality of LEDs 3a, and includes a first LED display unit A1, a second LED display unit A2, and a third LED display unit A3, each of which includes a segment unit. Is configured.
　また、操作部２には、ＬＥＤ表示部３を挟む位置に情報部１４が配置されている。すなわち、情報部１４は、ＬＥＤ表示部３に対応する位置（ここでは、ＬＥＤ表示部３の上部および下部）に設けられており、ＬＥＤ表示部３が点灯することで特定される、第１の情報部１５と第２の情報部１６を有している。 In the operation unit 2, an information unit 14 is arranged at a position sandwiching the LED display unit 3. That is, the information unit 14 is provided at a position corresponding to the LED display unit 3 (here, an upper part and a lower part of the LED display unit 3), and is specified by the LED display unit 3 being lit. An information unit 15 and a second information unit 16 are included.
　第１の情報部１５は、第１の溶接関連情報Ｂを表示し、第１の溶接関連情報Ｂとして、例えば図３に示すように第１の項目Ｂ１、第２の項目Ｂ２および第３の項目Ｂ３を表示する。 The first information unit 15 displays the first welding related information B. As the first welding related information B, for example, as shown in FIG. 3, the first item B1, the second item B2, and the third information are displayed. Item B3 is displayed.
　また、第２の情報部１６は、第２の溶接関連情報Ｃを表示し、第２の溶接関連情報Ｃとして、例えば図３に示すように第１の項目Ｃ１、第２の項目Ｃ２および第３の項目Ｃ３を表示する。 Moreover, the 2nd information part 16 displays the 2nd welding relevant information C, as shown in FIG. 3, for example, as shown in FIG. 3 item C3 is displayed.
　第１の溶接関連情報Ｂおよび第２の溶接関連情報Ｃのうち、第１の項目Ｂ１と第１の項目Ｃ１は、第１のＬＥＤ表示部Ａ１に対応する位置（Ａ１の上部および下部）に設けられている。同様に第２の項目Ｂ２と第２の項目Ｃ２は、第２のＬＥＤ表示部Ａ２に対応する位置（Ａ２の上部および下部）に設けられている。同様に第３の項目Ｂ３と第３の項目Ｃ３は、第３のＬＥＤ表示部Ａ３に対応する位置（Ａ３の上部および下部）に設けられている。ここで、第１の溶接関連情報Ｂと第２の溶接関連情報Ｃは、例えば、シールに印字されて操作部２の情報部１４に貼り付けられる、あるいは、操作部２の情報部１４の表面に直接印字する、などして操作部２の情報部１４に表示されている。 Of the first welding-related information B and the second welding-related information C, the first item B1 and the first item C1 are at positions corresponding to the first LED display portion A1 (upper and lower portions of A1). Is provided. Similarly, the second item B2 and the second item C2 are provided at positions (upper and lower portions of A2) corresponding to the second LED display portion A2. Similarly, the third item B3 and the third item C3 are provided at positions (upper and lower portions of A3) corresponding to the third LED display portion A3. Here, the first welding-related information B and the second welding-related information C are, for example, printed on a seal and attached to the information unit 14 of the operation unit 2, or the surface of the information unit 14 of the operation unit 2 The information is displayed on the information unit 14 of the operation unit 2 by printing directly on the screen.
　なお、切換部４は、ＬＥＤ表示部３の点灯するセグメント部１７ａ（ここでは、例えば、図３に示す第１のＬＥＤ表示部Ａ１、第２のＬＥＤ表示部Ａ２および第３のＬＥＤ表示部Ａ３）を切り換えるものである。決定部５は、ＬＥＤ表示部３のセグメント部１７ａが点灯している際に操作することで点灯しているセグメント部１７ａに対応する、情報部１４の溶接関連情報の項目を決定するものである。 In addition, the switching part 4 is the segment part 17a (here, for example, 1st LED display part A1, 2nd LED display part A2, and 3rd LED display part A3 which are shown in FIG. 3) which the LED display part 3 lights. ). The determination part 5 determines the item of the welding relevant information of the information part 14 corresponding to the segment part 17a lighted by operating when the segment part 17a of the LED display part 3 is lighted. .
　すなわち、本実施の形態１の溶接機１は、複数の溶接関連情報を選択して決定することで溶接条件を決定する機能を備えた溶接機であって、表示部３と、情報部１４と、切換部４と、決定部５と、を備え、切換部４と決定部５を操作することで溶接関連情報を選択して決定する構成からなる。ここで、表示部３は、複数のセグメント１７を有するＬＥＤ３ａを複数個備えている。情報部１４は、セグメント部１７ａに対応する位置に設けられており、セグメント部１７ａが点灯することで特定される溶接関連情報を表示する。切換部４は、点灯するセグメント部１７ａを切り換えることで、情報部１４の特定される溶接関連情報を切り換える。決定部５は、セグメント部１７ａが点灯している際に操作することで点灯しているセグメント部１７ａに対応する溶接関連情報を決定する。 That is, the welding machine 1 according to the first embodiment is a welding machine having a function of determining welding conditions by selecting and determining a plurality of welding-related information, and includes a display unit 3, an information unit 14, and the like. The switching unit 4 and the determining unit 5 are provided, and the welding related information is selected and determined by operating the switching unit 4 and the determining unit 5. Here, the display unit 3 includes a plurality of LEDs 3 a having a plurality of segments 17. The information part 14 is provided in the position corresponding to the segment part 17a, and displays the welding related information specified when the segment part 17a lights. The switching unit 4 switches the welding-related information specified by the information unit 14 by switching the segment portion 17a to be lit. The determination part 5 determines the welding relevant information corresponding to the segment part 17a which is lighted by operating when the segment part 17a is lighted.
　この構成により、ＬＥＤ表示部３を見ながら、切換部４と決定部５の操作を行うだけで溶接関連情報の設定が可能であり、簡単に最適な溶接条件を設定することが可能となる。これにより、溶接条件に関する知識が乏しい溶接作業の初心者でも溶接条件の設定を容易に行うことができる。 With this configuration, it is possible to set welding-related information simply by operating the switching unit 4 and the determining unit 5 while viewing the LED display unit 3, and it is possible to easily set optimal welding conditions. Thereby, even the beginner of the welding work with little knowledge regarding welding conditions can set welding conditions easily.
　また、液晶表示部や溶接条件設定用の複数のスイッチが必要ないことから、操作部２を簡素化でき、溶接機１の生産時間の短縮や溶接機１のコストダウンが可能である。 Also, since the liquid crystal display unit and a plurality of switches for setting welding conditions are not required, the operation unit 2 can be simplified, the production time of the welding machine 1 can be shortened, and the cost of the welding machine 1 can be reduced.
　以上のような操作部２を備えた溶接機１について、溶接を行う際の溶接パラメータを決定して設定する動作について説明する。 About the welding machine 1 provided with the above operation parts 2, the operation | movement which determines and sets the welding parameter at the time of welding is demonstrated.
　作業者は、モード設定部６を操作して、溶接機１に記憶されている溶接条件を再生するモードである溶接条件設定モードを選択する。溶接条件設定モードが選択されると、第１の溶接関連情報Ｂに対応して点灯する第１のＬＥＤ表示部Ａ１のうち、第１の溶接関連情報Ｂの第１の項目Ｂ１に対応するセグメント部１７ａが点灯する。この点灯は、第１の溶接関連情報Ｂのうち第１の項目Ｂ１を選択していることを示している。 The operator operates the mode setting unit 6 to select a welding condition setting mode that is a mode for reproducing the welding conditions stored in the welding machine 1. When the welding condition setting mode is selected, the segment corresponding to the first item B1 of the first welding-related information B among the first LED display parts A1 that are turned on corresponding to the first welding-related information B The part 17a lights up. This lighting indicates that the first item B1 is selected from the first welding related information B.
　ここで、第１の溶接関連情報Ｂの選択されている項目を変更するには、切換部４を操作する。切換部４を操作することで、第１の溶接関連情報Ｂのそれぞれの項目に対応したセグメント部１７ａが順々に点灯していく。 Here, to change the selected item of the first welding related information B, the switching unit 4 is operated. By operating the switching part 4, the segment part 17a corresponding to each item of the 1st welding related information B lights up one by one.
　例えば、第１の情報部１５の第１の溶接関連情報Ｂの第１の項目Ｂ１に対応するセグメント部１７ａが点灯している状態で、切換部４を一度操作すると、第１の溶接関連情報Ｂの第２の項目Ｂ２に対応するセグメント部１７ａへと、点灯するセグメント部１７ａが変わる。さらに切換部４の操作を行うと、点灯するセグメント部１７ａが変わる。そして、作業者の選択したい項目に対応するセグメント部１７ａが点灯している状態で決定部５を操作すると、その項目を選択したこととなる。 For example, when the switching unit 4 is operated once in a state where the segment portion 17a corresponding to the first item B1 of the first welding related information B of the first information unit 15 is lit, the first welding related information The segment portion 17a to be lit changes to the segment portion 17a corresponding to the second item B2 of B. When the switching unit 4 is further operated, the segment portion 17a to be lit changes. And if the determination part 5 is operated in the state in which the segment part 17a corresponding to the item which an operator wants to select lights, the item will be selected.
　上述の選択を行うと、続いて、第２の情報部１６の第２の溶接関連情報Ｃの項目を決定するための表示に変わり、第２の溶接関連情報Ｃの第１の項目Ｃ１に対応する第１のＬＥＤ表示部Ａ１のセグメント部１７ａが点灯する。そして、上述と同様に、切換部４と決定部５を操作することで、第２の情報部１６の第２の溶接関連情報Ｃの項目を決定する。 When the above selection is made, the display changes to the display for determining the item of the second welding related information C in the second information section 16 and corresponds to the first item C1 of the second welding related information C. The segment part 17a of the first LED display part A1 to be lit is turned on. And the item of the 2nd welding relevant information C of the 2nd information part 16 is determined by operating the switching part 4 and the determination part 5 similarly to the above-mentioned.
　すなわち、本実施の形態１の溶接機１の情報部１４は、表示部３の上側に設けられて第１の溶接関連情報Ｂを表示する第１の情報部１５と、表示部３の下側に設けられて第２の溶接関連情報Ｃを表示する第２の情報部１６と、を有する。そして、切換部４を操作すると、決定部５を操作するまでは、第１の溶接関連情報Ｂに対応するセグメント部１７ａの点灯が順次切り換えられる。そして、決定部５を操作して第１の溶接関連情報Ｂを決定した後は、切換部４を操作すると、決定部５を操作するまでは、第２の溶接関連情報Ｃに対応するセグメント部１７ａの点灯が順次切り換えられ、決定部５を操作することで第２の溶接関連情報Ｃを決定する構成としてもよい。ここで、切換部４を操作して決定部５を操作するまでの第１の溶接関連情報Ｂおよび第２の溶接関連情報Ｃに対応するセグメント部１７ａの点灯は、順次切り換えられるだけでなく、繰り返し切り換えられてもよい。 That is, the information unit 14 of the welding machine 1 according to the first embodiment includes a first information unit 15 that is provided on the upper side of the display unit 3 and displays the first welding-related information B, and a lower side of the display unit 3. And a second information unit 16 for displaying the second welding related information C. When the switching unit 4 is operated, the lighting of the segment unit 17a corresponding to the first welding related information B is sequentially switched until the determination unit 5 is operated. And after operating the determination part 5 and determining the 1st welding related information B, if the switching part 4 is operated, until the determination part 5 is operated, the segment part corresponding to the 2nd welding related information C The lighting of 17a may be sequentially switched, and the second welding related information C may be determined by operating the determination unit 5. Here, lighting of the segment part 17a corresponding to the 1st welding related information B and the 2nd welding related information C until it operates the switching part 4 and operates the determination part 5 is not only switched sequentially, It may be switched repeatedly.
　この構成により、溶接条件に関する知識が乏しい溶接作業の初心者でも溶接条件の設定を容易に行うことができる。また、液晶表示部や溶接条件設定用の複数のスイッチが必要ないことから、操作部２を簡素化でき、溶接機１の生産時間の短縮や溶接機１のコストダウンが可能である。 This configuration enables easy setting of welding conditions even for welding beginners with little knowledge of welding conditions. In addition, since the liquid crystal display unit and a plurality of switches for setting welding conditions are not required, the operation unit 2 can be simplified, the production time of the welding machine 1 can be shortened, and the cost of the welding machine 1 can be reduced.
　以上のようにして複数の溶接関連情報の項目の決定を行うと、溶接機１の記憶部に記憶された情報に基づいて、作業者が選択した複数の溶接関連情報の項目に適した溶接電流値などの溶接パラメータが読み出され、ＬＥＤ表示部３に読み出された溶接電流値が表示される。 When the items of the plurality of welding related information are determined as described above, the welding currents suitable for the items of the plurality of welding related information selected by the operator based on the information stored in the storage unit of the welding machine 1 are determined.

　すなわち、本実施の形態１の溶接機１は、第１の溶接関連情報Ｂと第２の溶接関連情報Ｃのうち、一方は溶接対象物の材質に関する情報であり、他方は溶接姿勢に関する情報である構成としてもよい。この構成により、溶接条件に関する知識が乏しい溶接作業の初心者でも溶接条件の設定を容易に行うことができる。 That is, in the welding machine 1 of the first embodiment, one of the first welding related information B and the second welding related information C is information related to the material of the welding object, and the other is information related to the welding posture. A certain configuration may be adopted. With this configuration, it is possible to easily set the welding conditions even for beginners of welding work with little knowledge about the welding conditions.

　また、７セグメントＬＥＤである第１のＬＥＤ表示部Ａ１の上部には、第１の溶接関連情報Ｂである「材質」の項目として、第１の項目Ｂ１である「軟鋼」の表示が設けられている。同様に第２のＬＥＤ表示部Ａ２の上部には、第１の溶接関連情報Ｂである「材質」の項目として、第２の項目Ｂ２である「ステンレス」の表示が設けられている。 Further, on the upper part of the first LED display portion A1 which is a 7-segment LED, a display of “soft steel” which is the first item B1 is provided as an item of “material” which is the first welding related information B. ing. Similarly, a display of “stainless steel” as the second item B2 is provided as an item of “material” as the first welding related information B on the upper part of the second LED display portion A2.

Similarly, in the lower part of the second LED display portion A2, as an item of “posture” which is the second welding-related information C, a display of “upward / standing” which is the second item C2 is provided. Yes.
　溶接作業者は、先ず、モード設定部６を操作して、溶接条件設定モードを選択する。溶接条件選択モードが選択されると、第１の溶接関連情報Ｂである「材質」のうち、第１の項目Ｂ１である「軟鋼」に対応する第１のＬＥＤ表示部Ａ１の上側のセグメント部１７ａが、図５に示すように点灯する。そうすると、第１の溶接関連情報Ｂの項目として「軟鋼」が選択されている表示となる。 First, the welding operator operates the mode setting unit 6 to select the welding condition setting mode. When the welding condition selection mode is selected, the segment portion on the upper side of the first LED display portion A1 corresponding to the “soft steel” that is the first item B1 among the “material” that is the first welding related information B 17a lights up as shown in FIG. If it does so, it will become the display in which "mild steel" is selected as an item of the 1st welding related information B.
　ここで、第１の溶接関連情報Ｂである「材質」の項目を、第１の項目Ｂ１である「軟鋼」から第２の項目Ｂ２である「ステンレス」に変更する場合には、切換部４を操作する。例えば、切換部４であるジョグダイヤルを回す。この操作により、第１の溶接関連情報Ｂである「材質」の第２の項目Ｂ２に対応した第２のＬＥＤ表示部Ａ２の上側のセグメント部１７ａが、図６のように点灯し、第１の溶接関連情報Ｂの項目として「ステンレス」が選択されている表示となる。 Here, when the item of “material” which is the first welding related information B is changed from “soft steel” which is the first item B1 to “stainless steel” which is the second item B2, the switching unit 4 To operate. For example, the jog dial which is the switching unit 4 is turned. By this operation, the upper segment portion 17a of the second LED display portion A2 corresponding to the second item B2 of “material” which is the first welding related information B is lit as shown in FIG. In this display, “stainless steel” is selected as the item of the welding related information B.
　なお、切換部４の操作を繰り返すと、決定部５を操作するまでは、図３に示す表示と図４に示す表示が、順次および繰り返し切り換えられる。そして、決定部５を操作することで、第１の溶接関連情報Ｂである「材質」の項目を決定する。 When the operation of the switching unit 4 is repeated, the display shown in FIG. 3 and the display shown in FIG. 4 are sequentially and repeatedly switched until the determination unit 5 is operated. And the item of "material" which is the 1st welding related information B is determined by operating the determination part 5. FIG.
　決定部５を操作して第１の溶接関連情報Ｂである「材質」の項目を決定すると、続いて、第２の溶接関連情報Ｃである「姿勢」の選択状態に切り換わり、その時の表示は図７に示すものとなる。すなわち、第２の溶接関連情報Ｃである「姿勢」の第１の項目Ｃ１である「下向」に対応する第１のＬＥＤ表示部Ａ１の下側のセグメント部１７ａが、図７に示すように点灯し、第２の溶接関連情報Ｃの項目として「下向」が選択されている表示となる。 When the item of “material” that is the first welding related information B is determined by operating the determining unit 5, the state is switched to the selection state of “posture” that is the second welding related information C, and the display at that time Is as shown in FIG. That is, the lower segment portion 17a of the first LED display portion A1 corresponding to the “downward” that is the first item C1 of “posture” that is the second welding related information C is as shown in FIG. Is displayed and “downward” is selected as the item of the second welding related information C.
　なお、第２の溶接関連情報Ｃの項目の決定についても、第１の溶接関連情報Ｂの項目の決定と同様に、切換部４と決定部５を用いて行う。切換部４の操作を繰り返すことで図７に示す表示と図８に示す表示が、順次および繰り返し切り換えられ、決定部５を操作することで第２の溶接関連情報Ｃの項目が決定される。 The item of the second welding related information C is determined using the switching unit 4 and the determining unit 5 in the same manner as the item of the first welding related information B. The display shown in FIG. 7 and the display shown in FIG. 8 are sequentially and repeatedly switched by repeating the operation of the switching unit 4, and the item of the second welding related information C is determined by operating the determination unit 5.
　そして、第２の溶接関連情報Ｃの項目を決定すると、続いて、第３の溶接関連情報Ｄである「溶接棒径」の選択状態に切り換わり、その時の表示は図９に示すものとなる。すなわち、第１のＬＥＤ表示部Ａ１、第２のＬＥＤ表示部Ａ２、第３のＬＥＤ表示部Ａ３およびＬＥＤ１３が点灯し、第２のＬＥＤ表示部Ａ２と第３のＬＥＤ表示部Ａ３に表示された数字により、溶接棒径として２．０ｍｍが選択されていることを示す。 Then, when the item of the second welding related information C is determined, the state is switched to the selection state of the “welding rod diameter” which is the third welding related information D, and the display at that time is as shown in FIG. . That is, the first LED display unit A1, the second LED display unit A2, the third LED display unit A3 and the LED 13 are turned on and displayed on the second LED display unit A2 and the third LED display unit A3. The numbers indicate that 2.0 mm is selected as the welding rod diameter.
　ここで、切換部４を操作すると、ＬＥＤ表示部３に表示される溶接棒径の値が、２．０ｍｍ以上、８．０ｍｍ以下の範囲で変化する。そして、作業者が使用する溶接棒径の値が表示されている状態で決定部５を操作すると、溶接棒径がその時に表示されている値に決定される。 Here, when the switching unit 4 is operated, the value of the welding rod diameter displayed on the LED display unit 3 changes in the range of 2.0 mm or more and 8.0 mm or less. And if the determination part 5 is operated in the state in which the value of the welding rod diameter which an operator uses is displayed, the welding rod diameter will be determined to the value currently displayed.
　以上のように、第１の溶接関連情報Ｂである「材質」の項目、第２の溶接関連情報Ｃである「姿勢」の項目および第３の溶接関連情報Ｄである「溶接棒径」の値が決定される。そうすると、上述の決定された事項に適した溶接電流などの溶接パラメータが読み出され、例えば図１０に示すようにＬＥＤ表示部３に溶接電流値が表示され、ＬＥＤ１２が点灯し、溶接条件が決定される。図１０では、溶接電流が１００Ａである溶接条件が表示され、決定されている。 As described above, the item of “material” as the first welding related information B, the item of “posture” as the second welding related information C, and the “welding rod diameter” as the third welding related information D are as follows. The value is determined. Then, the welding parameters such as the welding current suitable for the above-mentioned determined items are read out, for example, the welding current value is displayed on the LED display unit 3 as shown in FIG. 10, the LED 12 is lit, and the welding conditions are determined. Is done. In FIG. 10, a welding condition with a welding current of 100 A is displayed and determined.
　すなわち、本実施の形態１の溶接機１は、第１の溶接関連情報Ｂと第２の溶接関連情報Ｃを決定した後、表示部３に溶接棒の棒径が表示される。そして、切換部４を操作することで棒径の値が順次切り換えられ、決定部５を操作することで表示部３に表示されている値が棒径として決定される構成としてもよい。この構成により、溶接条件に関する知識が乏しい溶接作業の初心者でも溶接条件の設定を確実かつ容易に行うことができる。なお、切換部４を操作することで棒径の値が順次切り換えられるだけでなく、繰り返し切り換えられるようにしてもよい。 That is, after the welding machine 1 according to the first embodiment determines the first welding related information B and the second welding related information C, the bar diameter of the welding rod is displayed on the display unit 3. The bar diameter value may be sequentially switched by operating the switching unit 4, and the value displayed on the display unit 3 may be determined as the bar diameter by operating the determining unit 5. With this configuration, even welding beginners who have little knowledge about welding conditions can reliably and easily set welding conditions. It should be noted that by operating the switching unit 4, the value of the rod diameter may be switched repeatedly as well as being sequentially switched.
　また、第１の溶接関連情報Ｂ、第２の溶接関連情報Ｃおよび棒径が決定されると、第１の溶接関連情報Ｂ、第２の溶接関連情報Ｃおよび棒径の３つの情報に基づいて溶接条件の１つである溶接電流の値が決定されて表示部３に表示される構成としてもよい。この構成により、溶接条件に関する知識が乏しい溶接作業の初心者でも溶接条件の設定を確実かつ容易に手順よく行うことができる。 When the first welding-related information B, the second welding-related information C, and the rod diameter are determined, the first welding-related information B, the second welding-related information C, and the rod diameter are used. The welding current value, which is one of the welding conditions, may be determined and displayed on the display unit 3. With this configuration, even a beginner of a welding operation with little knowledge about welding conditions can set the welding conditions reliably and easily with good procedures.
　ここで、図２を用いて、溶接機１の動作について説明する。第１の記憶部７には、ＬＥＤ表示部３の点灯するセグメント部１７ａと、溶接関連情報の項目との関係が記憶されている。第２の記憶部８には、ＬＥＤ表示部３に表示する溶接棒径の範囲（例えば、２．０ｍｍ以上、８．０ｍｍ以下の溶接棒径）が記憶されている。第３の記憶部９には、第１の溶接関連情報Ｂの項目の値、第２の溶接関連情報Ｃの項目の値、第３の溶接関連情報Ｄの値および溶接条件である溶接電流値を対応付けたテーブルあるいは数式が記憶されている。第４の記憶部１０は、決定された溶接パラメータ、例えば溶接電流値を記憶しておくものである。 Here, the operation of the welding machine 1 will be described with reference to FIG. The first storage unit 7 stores the relationship between the segment portion 17a that the LED display unit 3 is turned on and the item of the welding related information. The second storage unit 8 stores a welding rod diameter range (for example, a welding rod diameter of 2.0 mm or more and 8.0 mm or less) displayed on the LED display unit 3. The third storage unit 9 includes a value of an item of the first welding related information B, a value of an item of the second welding related information C, a value of the third welding related information D, and a welding current value that is a welding condition. Is stored in a table or a mathematical expression associated with. The 4th memory | storage part 10 memorize | stores the determined welding parameter, for example, welding current value.
　制御部１１は、切換部４、決定部５およびモード設定部６の操作並びに第１の記憶部７や第２の記憶部８に記憶されている情報に基づいて、ＬＥＤ表示部３の表示を変化させる。また、制御部１１は、決定部５の操作および第１の記憶部７や第２の記憶部８に記憶されている情報に基づいて、選択された第１の溶接関連情報Ｂの項目、第２の溶接関連情報Ｃの項目および第３の溶接関連情報Ｄの項目の値を把握する。そして、これらの選択された情報と第３の記憶部９に記憶されている情報に基づいて溶接条件である溶接電流値を決定し、ＬＥＤ表示部３に表示させるとともに第４の記憶部１０に記憶し、溶接条件を決定する。そして、溶接機１は、決定された溶接電流値で溶接を行う。 The control unit 11 displays the LED display unit 3 based on the operation of the switching unit 4, the determination unit 5, and the mode setting unit 6 and the information stored in the first storage unit 7 and the second storage unit 8. Change. Moreover, the control part 11 is based on the operation | movement of the determination part 5, and the information memorize | stored in the 1st memory | storage part 7 or the 2nd memory | storage part 8, the item of the selected 1st welding related information B, the 1st. The value of the item of 2 welding related information C and the item of 3rd welding related information D is grasped | ascertained. And based on these selected information and the information memorize | stored in the 3rd memory | storage part 9, the welding current value which is welding conditions is determined, and it is made to display on the LED display part 3, and it is made to the 4th memory | storage part 10 Memorize and determine welding conditions. And the welding machine 1 welds with the determined welding current value.
　以上のように、本実施の形態１の溶接機１によれば、ＬＥＤ表示部３を見ながら、切換部４と決定部５を操作する。これにより、溶接対象物の「材質」、溶接の「姿勢」および使用する溶接棒の「溶接棒径」といった溶接条件を設定することが可能となる。そして、これら溶接条件を設定することで、設定した溶接条件に適した溶接電流値などの溶接パラメータが自動的に設定される。 As described above, according to the welding machine 1 of the first embodiment, the switching unit 4 and the determination unit 5 are operated while viewing the LED display unit 3. This makes it possible to set welding conditions such as the “material” of the welding object, the “posture” of welding, and the “welding rod diameter” of the welding rod to be used. And by setting these welding conditions, welding parameters, such as a welding current value suitable for the set welding conditions, are automatically set.
　したがって、溶接条件や溶接パラメータに関する知識や経験が乏しい溶接作業者であっても、溶接対象物の情報等の溶接条件を目視確認しながら、容易に順々に入力することができる。また、入力した溶接条件に適した溶接電流値等の溶接パラメータを溶接機１が自動的に設定するので、深い知識と豊富な経験が必要とされる溶接パラメータの設定作業において、溶接作業者が、溶接パラメータを設定しなくても良い。特に、溶接電流値等の溶接パラメータは、一般的に、勘や経験等に基づいて作業者が設定するものであり、溶接経験が浅い作業者にとっては難しい作業である。しかし、本実施の形態１の溶接機１では、ＬＥＤ表示部３を見ながら切換部４と決定部５を用いて溶接関連情報（溶接条件）を入力すれば、溶接機１が溶接パラメータを決定するので、特に、溶接経験が浅い作業者にとって非常に有用である。なお、溶接対象物の「材質」、溶接の「姿勢」および使用する溶接棒の「溶接棒径」は、溶接経験が浅い作業者にとっても理解しやすい情報である。このように理解しやすい情報だけを設定し入力するだけで、本来難しい作業である溶接電流値等の溶接パラメータが決定されるので、溶接経験が浅い作業者にとって非常に有用である。 Therefore, even a welding operator who has little knowledge and experience regarding welding conditions and welding parameters can easily input in order while visually checking the welding conditions such as information on the object to be welded. Further, since the welding machine 1 automatically sets welding parameters such as a welding current value suitable for the input welding conditions, the welding operator can set the welding parameters that require deep knowledge and abundant experience. It is not necessary to set the welding parameters. In particular, welding parameters such as a welding current value are generally set by an operator based on intuition, experience, and the like, and are difficult operations for an operator with little welding experience. However, in the welding machine 1 according to the first embodiment, if welding-related information (welding conditions) is input using the switching unit 4 and the determination unit 5 while looking at the LED display unit 3, the welding machine 1 determines the welding parameters. Therefore, it is very useful especially for an operator who has little experience in welding. The “material” of the welding object, the “posture” of welding, and the “welding rod diameter” of the welding rod to be used are information that can be easily understood by an operator who has little welding experience. As described above, welding parameters such as welding current values, which are inherently difficult operations, are determined simply by setting and inputting only information that is easy to understand. This is very useful for workers who have little experience in welding.
　また、液晶表示部のような文字情報を表示する部分が必要なく、英数字などを表示するための複数のセグメント１７を有するＬＥＤ３ａを複数個備えた表示部３のみで対応可能であることから、安価に実現可能である。そして、手棒溶接を行う場合に設定する溶接条件の数は少ないので、本実施の形態１は、手棒溶接用の溶接機に特に適している。 Further, since a portion for displaying character information such as a liquid crystal display portion is not necessary, it can be handled only by the display portion 3 including a plurality of LEDs 3a having a plurality of segments 17 for displaying alphanumeric characters and the like. It can be realized at low cost. And since there are few welding conditions set when performing hand bar welding, this Embodiment 1 is especially suitable for the welding machine for hand bar welding.
　なお、本実施の形態１では、表示部３のＬＥＤ３ａを３つ設けた例を示したが、ＬＥＤ３ａの数を増やして溶接関連情報の種類や、各溶接関連情報における項目の数を増やすこともできる。 In addition, in this Embodiment 1, although the example which provided three LED3a of the display part 3 was shown, increasing the number of LED3a and increasing the kind of welding relevant information and the number of items in each welding relevant information may be increased. it can.
　例えば、図１１に示すように、ＬＥＤ３ａを４つ設け、４つのＬＥＤ３ａに対応するように、溶接関連情報の項目を設けることで、図４に示す場合と比べて、１つの溶接関連情報についてより多くの項目が選択可能となる。なお、図１１では、溶接関連情報として、第２の情報部に「接続状態」と「継手」を示す表示を設けた例を示している。 For example, as shown in FIG. 11, by providing four LEDs 3a and providing items of welding related information so as to correspond to the four LEDs 3a, compared with the case shown in FIG. Many items can be selected. In addition, in FIG. 11, the example which provided the display which shows a "connection state" and a "joint" in the 2nd information part as welding related information is shown.
　また、例えば、図１２に示すように、ＬＥＤ３ａを４つ設け、２つのＬＥＤ３ａをセットにして溶接関連情報の項目を選択するようにすることで、４つの溶接関連情報に対応することが可能となる。図１２の場合、溶接関連情報として、第１の情報部１５で「材質」および「パルス有無」を示し、第２の情報部１６で「姿勢」および「クレータ有無」を示し、全部で４つの溶接関連情報について、項目を選択することができる。すなわち、図１１の場合と比べ、より多くの溶接関連情報に対応することが可能となる。なお、図１２の場合、１つの溶接関連情報の項目の数は、それぞれ２つである。 Also, for example, as shown in FIG. 12, four LEDs 3a are provided, and by setting the two LEDs 3a and selecting items of welding related information, it is possible to correspond to four welding related information. Become. In the case of FIG. 12, as the welding related information, the first information part 15 indicates “material” and “presence / absence of pulse”, the second information part 16 indicates “posture” and “presence / absence of crater”. Items can be selected for welding related information. That is, as compared with the case of FIG. 11, it becomes possible to cope with more welding related information. In the case of FIG. 12, the number of items of one welding related information is two each.
　また、本実施の形態１では、７セグメントＬＥＤを使用する例を示したが、図１３に示す１６個のセグメント１７を含んで構成される１６セグメントＬＥＤ等を使用するようにしてもよい。１６セグメントＬＥＤを使用した場合、図１３に示すように、例えば１つのＬＥＤ３ｂで１つの溶接関連情報に対して３つの項目を選択することが可能となる。図１３Ａは、「軟鋼」が選択されていることを表すセグメント部１７ｂが点灯している例を示しており、図１３Ｂは、「銅」が選択されていることを表すセグメント部１７ｂが点灯している例を示している。また、図１３Ｃは、「アルミ」（アルミニウム）が選択されていることを表すセグメント部１７ｂが点灯している例を示している。 In the first embodiment, an example in which a 7-segment LED is used is shown. However, a 16-segment LED that includes 16 segments 17 shown in FIG. 13 may be used. When 16 segment LED is used, as shown in FIG. 13, it is possible to select three items for one welding related information with one LED 3b, for example. FIG. 13A shows an example in which the segment portion 17b indicating that “mild steel” is selected is lit, and FIG. 13B indicates that the segment portion 17b indicating that “copper” is selected is lit. An example is shown. FIG. 13C shows an example in which the segment portion 17b indicating that “aluminum” (aluminum) is selected is lit.
　このように、セグメント１７数の多いＬＥＤ３ｂを使用すると１つのＬＥＤ３ｂの上部のみで１つの溶接関連情報を表示することもできる。また、図１３Ａ、図１３Ｂおよび図１３ＣのそれぞれのＬＥＤ３ｂの下部に第２の情報部１６として別の溶接関連情報の項目を並べて、同様にセグメント部１７ｂを点灯させることで１つの項目を選択させることもできる。 As described above, when the LED 3b having a large number of segments 17 is used, one welding-related information can be displayed only on the top of one LED 3b. Further, another welding-related information item is arranged as the second information portion 16 below each LED 3b in FIGS. 13A, 13B, and 13C, and one item is selected by lighting the segment portion 17b in the same manner. You can also.
　本発明のアーク溶接機は、液晶表示部や複数の溶接条件設定用のスイッチ部などを用いることなく安価で簡単な構成とし、溶接条件に関する知識が乏しい溶接作業の初心者でも簡単な操作で溶接条件の設定および溶接パラメータの決定ができる。これにより、溶接条件を設定して溶接を行う溶接機として産業上有用である。 The arc welding machine of the present invention has an inexpensive and simple configuration without using a liquid crystal display section or a plurality of welding condition setting switches, and even welding beginners who have little knowledge about welding conditions can easily operate welding conditions. And welding parameters can be determined. Thereby, it is industrially useful as a welding machine which sets welding conditions and performs welding.
