Description

本発明は、溶接機を形成する溶接電源装置に備えられたノーヒューズ・ブレーカの遠隔制御に関するものである。   The present invention relates to remote control of a no-fuse breaker provided in a welding power source device forming a welding machine.

溶接機に緊急事態が発生したとき、作業者が溶接電源装置に設けられたノーヒューズ・ブレーカをオフすることで対処していた。しかし、溶接を行う作業場が狭いところでは、作業者が限定された狭い空間を移動しなければならず、ノーヒューズ・ブレーカをオフするのに時間を必要とした。   When an emergency occurred in the welding machine, the worker handled it by turning off the no-fuse breaker provided in the welding power supply. However, where the work place where welding is performed is narrow, the worker has to move in a limited narrow space, and it takes time to turn off the no-fuse breaker.

図３を用いて従来技術に溶接機２０について説明する。
図３に示す溶接電源装置２１は、商用交流電源ＡＣを通電又は遮断するノーヒューズ・ブレーカ２３と、ノーヒューズ・ブレーカ２３から供給される商用交流電源ＡＣをアーク溶接に適した直流の出力電力で生成して出力する主回路４と、主回路４を出力制御する主制御回路２２と、で形成されている。 A conventional welding machine 20 will be described with reference to FIG.
A welding power source device 21 shown in FIG. 3 has a no-fuse breaker 23 for energizing or cutting off the commercial AC power source AC, and a commercial AC power source AC supplied from the no-fuse breaker 23 with a DC output power suitable for arc welding. The main circuit 4 that generates and outputs and the main control circuit 22 that controls the output of the main circuit 4 are formed.

溶接電源装置２１の一方の出力端子は、電力線と通信線とが混在した接続ケーブル２６を介して送給装置２５に接続され、送給装置２５は同じく接続ケーブル２６を介して溶接トーチ２４に接続される。溶接電源装置２１の他方の出力端子は、接地用ケーブル１５を介して被加工物１２に接続される。   One output terminal of the welding power source device 21 is connected to the feeding device 25 via a connection cable 26 in which power lines and communication lines are mixed, and the feeding device 25 is also connected to the welding torch 24 via the connection cable 26. Is done. The other output terminal of the welding power source device 21 is connected to the workpiece 12 via the grounding cable 15.

図３に示す送給装置２５は、主制御回路２２の出力制御に応じてワイヤ電極１１を溶接トーチ２４に送給する。 The feeding device 25 shown in FIG. 3 feeds the wire electrode 11 to the welding torch 24 in accordance with the output control of the main control circuit 22.

溶接トーチ２４は、ワイヤ電極１１からのアーク発生とともに、そのアークの周囲（電極１１の周囲）にシールドガスの噴射が行われる。即ち、ガス貯蔵装置１４と送給装置２５との間及び送給装置２５と溶接トーチ２４との間は、ガス貯蔵装置１４にて貯蔵されたシールドガスが送給ホース１７を介して送給される。ガス貯蔵装置１４には、ガスの送給量を調整する図示省略のガスレギュレータ１３が備えられ、該レギュレータは、主制御回路２２の制御に基づき、溶接トーチ２４へのガスの送給量（トーチ２４からの噴射量）の調整を行う。   As the welding torch 24 generates an arc from the wire electrode 11, the shielding gas is injected around the arc (around the electrode 11). That is, the shield gas stored in the gas storage device 14 is supplied via the supply hose 17 between the gas storage device 14 and the feeding device 25 and between the feeding device 25 and the welding torch 24. The The gas storage device 14 includes a gas regulator 13 (not shown) that adjusts the gas supply amount. The regulator supplies the gas supply amount (torch) to the welding torch 24 based on the control of the main control circuit 22. The injection amount from 24) is adjusted.

溶接トーチ２４は、作業者の手動操作が可能な操作スイッチ９が備えられている。操作スイッチ９は、アーク溶接の開始や停止（オン・オフ）、出力電流・電圧といったパラメータ調整等、溶接に係る操作指令が可能であり、接続ケーブル２６を介して主制御回路２２に送信される。 The welding torch 24 is provided with an operation switch 9 that can be manually operated by an operator. The operation switch 9 is capable of operating commands relating to welding such as arc welding start / stop (on / off), parameter adjustment such as output current / voltage, and the like, and is transmitted to the main control circuit 22 via the connection cable 26. .

しかし、溶接作業中において、何らかの原因で溶接電源装置２１に危急事態が発生し、安全確保等のために溶接電源装置に設けられているノーヒューズ・ブレーカ２３まで作業者が移動してオフしていた。しかし、作業場が手狭で溶接電源装置まで距離があるとき、作業者が溶接電源装置２１まで俊敏に移動できず、危急事態の対応が遅れてしまう。
そこで、例えば、特許文献１に示すように、溶接電源装置２１にマイク、音声認識回路及びブレーカ駆動回路を設け、危急事態が発生したときに、作業者がマイクに向かって大声で、例えば、停止と発してノーヒューズ・ブレーカをオフさせていた。 However, during the welding operation, an emergency situation has occurred in the welding power source device 21 for some reason, and the worker has moved to the no-fuse breaker 23 provided in the welding power source device to ensure safety and turned off. It was. However, when the work place is narrow and there is a distance to the welding power source device, the worker cannot move quickly to the welding power source device 21 and the response to the emergency situation is delayed.
Therefore, for example, as shown in Patent Document 1, a welding power supply device 21 is provided with a microphone, a voice recognition circuit, and a breaker drive circuit. When an emergency situation occurs, the operator speaks loudly toward the microphone, for example, stops. And turned off the no-fuse breaker.

つぎに、動作について説明する。
作業者が溶接電源装置２に危急事態を確認し、図１に示すノーヒューズ・ブレーカ３をオフする必要があると判断したとき、作業者が溶接トーチの操作スイッチ９を所定時間内に所定回数オン・オフを繰り返して音声認識モードを選択すると、主制御回路５は音声認識モードが選択されたと認識する。 Next, the operation will be described.
When an operator confirms an emergency situation with the welding power source device 2 and determines that the no-fuse breaker 3 shown in FIG. 1 needs to be turned off, the operator turns the operation switch 9 of the welding torch a predetermined number of times within a predetermined time. When the voice recognition mode is selected by repeating ON / OFF, the main control circuit 5 recognizes that the voice recognition mode is selected.

続いて、作業者は、溶接トーチに設けられたマイク１０に向かって、例えば、大きな声で停止と怒鳴ると、溶接トーチに設けられた図示省略の変換処理回路により、マイク１０からの音声（アナログ）を音声信号（デジタル）に変換し、主制御回路５は、受信した音声信号をアナログに変換し音声の音量と予め定めた音量基準値と比較し、音量が音量基準値より大きくなるとブレーカ駆動回路６を動作させる。
このとき、音声をデイタル信号に変換し、接続ケーブル１６を介して有線で送信するのでノイズの影響を抑制できる。 Subsequently, when the worker makes a loud voice and stops and shouts toward the microphone 10 provided on the welding torch, for example, a voice (analogue) from the microphone 10 is obtained by a conversion processing circuit (not shown) provided on the welding torch. ) Is converted into an audio signal (digital), and the main control circuit 5 converts the received audio signal into analog, compares the audio volume with a predetermined volume reference value, and drives the breaker when the volume exceeds the volume reference value. The circuit 6 is operated.
At this time, since the sound is converted into a digital signal and transmitted by wire via the connection cable 16, the influence of noise can be suppressed.

ブレーカ駆動回路６は、図２に示すノーヒューズ・ブレーカ３に内蔵されているコイルに所定の電圧を印加してスイッチＳＷ１〜ＳＷ３をオフし、溶接電源装置に商用交流電源ＡＣの供給を遮断する。   The breaker drive circuit 6 applies a predetermined voltage to the coil built in the no-fuse breaker 3 shown in FIG. 2 to turn off the switches SW1 to SW3, thereby cutting off the supply of the commercial AC power supply AC to the welding power supply device. .

溶接トーチ８の所定に位置にマイク１０を配設しているが、図１の点線で示すマイクに接続線を設け、溶接トーチ８に図示省略の接続部を設け、接続線を介してマイク１０を溶接トーチ８に接続してもよい。このとき、マイクは、例えば、耳掛け式のマイクであり、装着した作業者からの音声を取得する。   Although the microphone 10 is disposed at a predetermined position of the welding torch 8, a connection line is provided on the microphone indicated by a dotted line in FIG. 1, a connection portion (not shown) is provided on the welding torch 8, and the microphone 10 is connected via the connection line. May be connected to the welding torch 8. At this time, the microphone is, for example, an ear-hook type microphone, and acquires sound from the worker who wears it.

また、外部の雑音による誤動作を抑制するために、受信した音声の音量が音量基準値を越えて所定時間（例えば、１秒）が経過した後にブレーカ駆動回路６を動作させてもよい。 In order to suppress malfunction due to external noise, the breaker driving circuit 6 may be operated after a predetermined time (for example, 1 second) has elapsed after the volume of the received voice exceeds the volume reference value.

次に、本実施形態の特徴的な効果を記載する。
（１）溶接電源装置まで移動するのに距離があり移動時間を必要とする作業現場において、溶接トーチに設けられたマイクに向かって大声で、例えば、停止と話すと、作業者が遠隔からノーヒューズ・ブレーカがオフできるので、危急事態に対する処理が早く行うことができる。
（２）マイクからの音声（アナログ）を音声信号（デジタル信号）に変換し制御線を介して有線で主制御回路まで送信するので、作業者と溶接電源装置とが、例えば、１０ｍ〜２０ｍも離れ、更に作業場周辺のノイズが非常に大きくてもノイズの影響を受けず遠隔からノーヒューズ・ブレーカを精度良くオフできる。更に、音声信号の溶接トーチから主制御回路５への送信は、既存の接続ケーブル１６の制御線を併用することで、音声信号に使用する制御線を別途用意しなくても済む。 Next, characteristic effects of the present embodiment will be described.
(1) In a work site where there is a distance to move to the welding power source and requires a moving time, when the speaker speaks loudly toward the microphone provided on the welding torch, for example, when the operator stops, the worker can Since the fuse breaker can be turned off, an emergency can be processed quickly.
(2) Since voice (analog) from the microphone is converted into a voice signal (digital signal) and transmitted to the main control circuit via a control line, the operator and the welding power supply device, for example, 10 m to 20 m Even if the noise around the work place is very large, the no-fuse breaker can be accurately turned off remotely without being affected by the noise. Furthermore, the audio signal is transmitted from the welding torch to the main control circuit 5 by using the control line of the existing connection cable 16 together, so that it is not necessary to separately prepare a control line used for the audio signal.
