Abstract
Description
このような溶接を行う溶接加工装置において、レーザ溶接そのものは比較的短時間で完了することができる。これに比べて、ブランク材の搬入や位置決めは、時間がかかる。このため、ブランク材の搬入、位置決め、レーザ溶接、及び搬出までの工程を、同一場所にて行うと、全体としての作業時間は、一番時間のかかる工程に引きずられて長くなる。
請求項2の溶接加工装置は、請求項1において、溶接前の複数のブランク材が載置される搬入ステーションと、前記完成品が載置されるべき搬出ステーションと、前記搬入ステーション上のブランク材を、前記位置決めステーションにある前記第1または第2テーブルの上に移動する第1移動装置と、前記溶接ステーションで溶接が完了した後に、前記位置決めステーションに移動した前記第1テーブルまたは第2テーブル上の完成品を、前記搬出ステーションに移動する第2移動装置とを更に備えたことを特徴とする。
請求項5の溶接加工装置は、請求項1において、前記第1及び第2テーブルが、前記複数のブランク材を位置決めする位置決めデバイスを備えていることを特徴とする。
請求項7の溶接加工装置は、請求項5において、前記複数のブランク材が少なくとも第1ブランク材と第2ブランク材を含み、前記第1ブランク材を前記位置決めデバイスにより予め定められた位置に配置し、次いで前記第1ブランク材を前記固定デバイスにより前記第1及び第2テーブルの一方に固定し、さらに前記第1ブランク材に第2ブランク材を突き合わせるべく押圧させた状態で前記第2ブランク材を前記固定デバイスにより前記第1及び第2テーブルの他方に固定させることを特徴とする。
請求項9の溶接加工装置は、請求項1において、前記固定デバイスが、前記複数のブランク材の下面をそれぞれ吸着する吸着ユニットを備えていることを特徴とする。
請求項5の溶接加工装置において、前記ブランク材は、前記テーブルに備えられた位置決めデバイスにより、第1又は第2テーブル上の定められた位置に位置決めされる。
請求項7の溶接加工装置において、第1ブランク材を前記位置決めデバイスより位置決めする。次に、第1ブランク材を固定デバイスによりテーブルに固定する。次に、第1ブランク材に第2ブランク材を突き合わせるべく押圧させた状態で第2ブランクを固定デバイスによりテーブルに固定する。これにより、両ブランク材がテーブル上に位置決めされ、かつ固定される。したがって、第1ブランク材に対して第2ブランク材を精度良く位置決めすることができる。
請求項9の溶接加工装置において、固定デバイスが、各ブランク材の下面を吸着する吸着ユニットを備えているので、ブランク材の上面にクランプ等が突出しない。これにより、レーザ溶接を行う前記溶接ヘッドの移動に制約がなく、同溶接ヘッドの高速移動が可能となる。
本溶接加工装置は、図1に開示されるように、溶接ステーション2と、この溶接ステーション2の一側に配置された第1位置決めステージ4と、他側に配置された第2位置決めステージ6とを備えている。この第1位置決めステージ4と、第2位置決めステージ6で、位置決めステーションを形成している。これらの溶接ステーション2及び位置決めステーション(第1位置決めステージ4、第2位置決めステージ6)に亘ってレール8が設けられている。第1テーブル10と第2テーブル12は、このレール8上を移動する。すなわち、第1テーブル10は、レール8に沿って第1位置決めステージ4と溶接ステーション2とを移動可能である。また、第2テーブル12は、レール8に沿って溶接ステーション2と第2位置決めステージ6とを移動可能である。溶接ステーション2には、ブランク材Bを溶接する溶接装置14が設けられている。各テーブル10及び12は、ブランク材Bをテーブル上に位置決めし、かつ固定する機能を有している。これらの機能については後述する。
ここで、第1及び第2テーブル10及び12と、各ロボット20,22,24,26と、各ターンテーブル30及び34の作動を互いに関連付けて説明する。
溶接ステーション2における溶接作業が完了し、かつ第2位置決めステージ6におけるブランク材Bの載置が完了すると、完成品Cを載せた第1テーブル10が再び第1位置決めステージ4に移動する。同時に、ブランク材Bを載せた第2テーブルが溶接ステーション2に移動する。
そして、第1位置決めステージ4及び溶接ステーション2での作業が完了すると、第1テーブル10は溶接ステーション2に移動し、第2テーブル12は第2位置決めステージ6に移動する。
第1及び第2テーブル8及び12と、各ロボット20,22,24,26と、各ターンテーブル20及び34は、以上のような作動を繰り返し行うものである。
次に、溶接ステーション2における溶接デバイス14を、図2及び図3を参照して説明する。
次に、各テーブル10及び12にそれぞれ設けられているブランク材Bの位置決めデバイス及び固定デバイスを図4及び図5を参照して説明する。
そして、この溶接加工装置においては、まずブランク材B1を位置決めした上でテーブル10,12に固定し、次いでブランク材B2、B3,B4を位置決めしてテーブル10,12に固定する。
上述の位置決めデバイスは、各ブランク材B2,B3及びB4をブランク材B1に当接するように押圧したときに、一方のブランク材が他方のブランク材に乗り上げることを防止するための装置を有している。ここでは、ブランク材B1とB2と関係において設けられた装置を説明する。
この実施形態に係る溶接加工装置は、溶接ステーション42と、同溶接ステーション2の一側に配置された位置決めステーション44とを備えている。第1テーブル50は下部レール46に沿ってスライド可能である。第2テーブル52は上部レール48に沿ってスライド可能である。すなわち、第1テーブル50は、下部レール46に沿って位置決めステーション44と溶接ステーション42とを移動可能である。また、第2テーブル52は、上部レール48に沿って位置決めステーション44と溶接ステーション42とを移動可能である。溶接ステーション42には、ブランク材Bを溶接する溶接装置54が設けられている。第1及び第2テーブル50及び52は、ブランク材Bをテーブル上に位置決めし、かつ固定する機能を有している。
ここで、第1及び第2テーブル50及び52と、各ロボット60及び62と、各ターンテーブル66及び70の動作を互いに関連付けて説明する。
溶接ステーション42における溶接作業が完了し、かつ位置決めステーション44におけるブランク材Bの載置が完了すると、完成品Cを載せた第1テーブル50が再び下部レール46に沿って位置決めステーション44に移動する。同時に、ブランク材Bを載せた第2テーブル52が上部レール48に沿って溶接ステーション42に移動する。
そして、位置決めステーション44及び溶接ステーション42での作業が完了すると、第1テーブル50は下部レール46に沿って溶接ステーション42に移動し、第2テーブル52は上部レールに沿って位置決めステーション44に移動する。
第1及び第2テーブル50及び52と、各ロボット60及び62と、各ターンテーブル66及び70は、以上のような作動を繰り返し行うものである。
次に、溶接ステーション42における溶接装置54を、図10及び図11を参照して説明する。
以上より明らかなように、この第2の実施形態に係る溶接加工装置において、ブランク材Bが固定される第1及び第2のテーブル50及び52は、位置決めステーション44と溶接ステーション42とを交互に移動する。そして溶接ステーション42において、一方のテーブル50または52上に固定されたブランク材Bを溶接する作業が行われているときに、位置決めステーション44において他方のテーブル50または52上にブランク材Bを位置決め・固定する作業が行われる。したがって、第1実施形態の場合と同様に、ブランク材Bの溶接と位置決めを同時に行うことができるので、全体の作業時間を短縮できる。しかも、ブランク材Bに対して同じ溶接を行う限り、溶接ステーション42は1つで足りるので、従来装置に比べてスペース的に格段に有利である。しかも、第1テーブル50と第2テーブル52が異なる高さを移動するので、1つの位置決めステーション44で足り、第1の実施形態の溶接加工装置よりも、平面視における装置全体をコンパクトにすることができる。
以上で、本発明の実施形態の説明を終えるが、本発明は上述した実施形態に限定されるものではない。
上述した各実施形態において、溶接装置14または54は、いずれも溶接ヘッド14fまたは54fが、レール8または48と平行に延びたレール14aまたは54aに沿って移動されるように構成されているが、代わりに溶接ステーション2または42において、溶接されるブランク材が載置されたテーブル
10,12または50,52を、レール8または48に沿って移動させるようにすることも可能である。ガイド部材36に関しても、例えばブランク材の突き合わせ部分を上方から押さえ込むようなブロック体をテーブル10,12に設けることが可能である。
図示したように、テーブル10,12(50,52)は、駆動源100と接続されている。この駆動源100が駆動することで、テーブル10,12は上述したレール8(46,48)をスライドして移動する。この移動タイミングや速度等は、駆動源100と接続された制御部102にて制御されている。なお、テーブル10,12は必要に応じて手動でスライドさせることも可能である。
