【発明の属する技術分野】
この発明は、ワークを搬送支持する台車上に、ワークに対して複数箇所を支持する支持部を備えたワーク搬送支持装置およびワーク搬送支持方法に関する。
【0002】
【従来の技術】
自動車の車体部品を搬送する装置としては、特許文献1に記載のものがある。
【0003】
【特許文献1】
特開2000−53041号公報
【0004】
従来車体部品として例えばボディサイドを、起立状態で搬送支持する際には、搬送方向に沿って移動する台車上に、車体下部側の車体前後方向両端部付近を支持する前後2箇所の支持部を設定している。この2箇所の支持部のうち一方は、各車種共通のものであり、他方は、各車種の車体の前後方向長さに対応できるよう各車種専用のものを複数設けている
【0005】
【発明が解決しようとする課題】
しかしながら、上記した従来のものは、他方の支持部を各車種専用のものとして複数設けているので、使用しない支持部が、ワークに対して例えば溶接作業を行うなどの加工作業を行うに際して邪魔になり、加工作業が困難になるという問題がある。
【0006】
そこで、この発明は、搬送支持されるワークに対する加工作業の際に、ワークを支持する支持部が邪魔になることなく、加工作業を容易に行えるようにすることを目的としている。
【0007】
【課題を解決するための手段】
前記目的を達成するために、この発明は、ワークを搬送支持する台車上に、前記ワークに対して複数箇所を支持する支持部を備え、前記複数の支持部のうち少なくとも一つを、他の支持部に対して接近離反する方向に移動可能に設け、この移動可能な支持部に、その移動方向任意の位置で固定する固定手段を設け、前記移動可能な支持部に該支持部の連結部を介して着脱可能に連結してこの支持部を移動させる外部駆動機構を設けたワーク搬送支持装置であって、前記固定手段は、前記移動可能な支持部を固定している状態で、流体圧の供給を受けてこの固定状態を解除する構造であり、この固定解除に用いる作動流体を、前記外部駆動機構から前記連結部を通して供給し、前記連結部に、前記固定手段に流体を供給する流体供給口を設ける一方、前記外部駆動機構には前記連結部に連結する連結部材を設け、この連結部材の先端に、前記流体供給口上に配置されて該流体供給口に接続される流体送給口を設けた構成としてある。
【0008】
【発明の効果】
この発明によれば、ワークを搬送支持する複数の支持部のうちの少なくとも一つを、他の支持部に対して接近離反する方向に移動可能に設け、その移動させた任意の位置で固定するようにしたため、この移動可能な一つの支持部により複数種のワークに対応でき、各種ワーク専用の支持部を複数設ける必要がなく、これによりワークに対する加工作業時において、支持部が邪魔になることがなく、加工作業を容易に行うことができる。
また、外部駆動機構の連結部材の先端を支持部の連結部に連結したときに、連結部の流体供給口と連結部材の流体送給口とが接続されるので、固定手段の固定状態を解除する際の流体供給のための専用の接続時間が不要となり、作業時間の短縮化を図ることができる。
【0009】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づき説明する。
【0010】
図1は、この発明の実施の一形態を示すワーク搬送支持装置の要部の斜視図、図2は、このワーク搬送支持装置によりワークWを支持した状態を示す簡略化した正面図である。
【0011】
ここでのワークWは、自動車の車体パネルを構成するボディサイドであり、このボディサイドを起立状態として、その車体下部側の車体前後方向(図2中で左右方向)の2箇所を、支持部1および、この支持部1に対して接近離反する方向に移動可能な支持部3により支持している。
【0012】
上記した各支持部1,3は、いずれも複数車種共通のものであり、図2中で左右方向に延びるガイド部5に沿って移動する台車7上に設けてある。台車7は、車体前後方向の複数箇所(ここでは3箇所)にて、ガイド部5を上下から挟むようにして設けてあるガイドローラ9を備えている。この台車7を、ガイド部5に沿って移動させることで、支持しているワークWを所定の位置まで搬送し、この搬送位置で溶接作業などの加工作業を行う。
【0013】
一方の支持部1は、台車7上に固定してある。他方の支持部3については、図1に示すように、台車7の長手方向に沿って延びるリニアガイドレール11を設け、このリニアガイドレール11に移動体13を移動可能に設けている。移動体13の側部には、上方に突出してその先端でワークWを受け入れる二つのワーク受け15,17を、支持部3の移動方向と交差する方向に沿って並列に配置してある。この各ワーク受け15,17は、ワークWの形状に応じて使い分ける。
【0014】
上記した移動体13の移動方向側の側部(図2中で移動体13の左側)には、移動体13とともに、前記したリニアガイドレール11にガイドされて移動する固定手段としてのガイドロック19を設けてある。ガイドロック19は、図1のA矢視図(一部断面)に相当する図3に示すように、上部に移動体13側に突出する支持突起19aを備え、一方移動体13は、この支持突起19aの下方に位置する凸部13aを備えている。
【0015】
そして、支持突起19aおよび凸部13aに、貫通孔19bおよび貫通孔13bをそれぞれ形成して、この各貫通孔19b,13bに、上方からガイドピン21を挿入して両者を連結する。このガイドピン21による連結は、移動体13とガイドロック19とが図3中で上下に相対移動可能となるようにする。
【0016】
上記したガイドロック19は、図示していないが、リニアガイドレール11を、例えばその両側から挟み込むか、あるいは下方に向けて押し付けることで固定しており、この固定状態を、作動流体としてのエアの供給を受けて解除する構造とする。
【0017】
また、支持部13の側方には、移動体13をリニアガイドレール11に沿って移動させる外部駆動機構23を配置してあり、支持部13の前記したワーク受け15,17と反対側の側部には、この外部駆動機構23に着脱可能に連結する連結部25を設けてある。連結部25には、前記したガイドロック19にエアを供給するエア供給口27を設け、このエア供給口27とガイドロック19とはエア供給配管29によって接続してある。なお、図2では、外部駆動機構23を省略してある。
【0018】
外部駆動機構23は、連結部25に連結する連結部材として合体用アーム31と、この合体用アーム31を、連結部25に連結する連結位置と連結を解除した非連結位置との間を移動させる連結部材駆動手段としての駆動シリンダ33と、この駆動シリンダ33を、支持部3の移動方向に移動させる支持部駆動手段としての支持部駆動ユニット35とをそれぞれ備えている。
【0019】
図4は、支持部3の連結部25に外部駆動機構23の合体用アーム31を連結した状態を示す図5のB矢視図で、外部駆動機構23は、台車7より下方位置に、ベース板37を設けてあり、このベース板37上に、前記した支持部駆動ユニット35を設けてある。図6は、図4の平面図である。
【0020】
なお、図1および図5では、上記した支持部駆動ユニット35の詳細な構造は省略してある。
【0021】
支持部駆動ユニット35は、ベース板37上にハウジングベース39を固定しこのハウジングベース39の図3中で左右両端付近に立設した支持板39aに、ねじ棒41を回転可能に支持させたボールねじを備え、ねじ棒41にボールガイドナット43を結合してある。図4,図6に示すように、ハウジングベース39の台車7と反対側の側方には、モータ45を配置してあり、このモータ45に連結したプーリ47と、ねじ棒41の端部に連結したプーリ49とを、ベルト51により連結している。
【0022】
ボールガイドナット43の上部には、支持ブラケット53を取り付けてある。支持ブラケット53は、図4に示すように、台車7に向けて斜めに上方に突出しており、その突出先端側に、前記した合体用アーム31の基端側に設けてある取付具55の一端側(下端側)を、支持軸57を介して回転可能に取り付けてある。
【0023】
一方、支持ブラケット53の基端側の台車7と反対側の側部に形成してある取付部53aには、前記した駆動シリンダ33を、支持軸59を介して回転可能に取り付けてある。駆動シリンダ33の上方に延びるピストンロッド61の先端は、上記した取付具55の図4中で右方向に突出した他端側に、支持軸63を介して回転可能に連結してある。
【0024】
合体用アーム31の先端には、前記した支持部3の連結部25に連結するアーム側連結部65を備えている。このアーム側連結部65は、連結部25を両側から挟むように先端が二股状となる一対の連結突起65aを備え、この連結突起65a相互間には、連結部25上に配置されるエア送給口65bを設けている。
【0025】
上記したエア送給口65bには、エア導入配管67を接続し、図4〜図6のように連結部25とアーム側連結部65とが連結した状態で、エア導入配管67と支持部3側のエア供給配管29とが連通状態となる。
【0026】
また、外部駆動機構23における支持ブラケット53の先端には、上方に延びるストッパ53bを設けてあり、アーム側連結部65を連結部25に連結したときに、取付具55がこのストッパ53bに当接して連結状態の位置決めを行う。
【0027】
次に作用を説明する。図1の状態は、支持部3の連結部25と、外部駆動機構23のアーム側連結部65とが、支持部3の移動方向と直交する方向の位置が一致している。この状態で、駆動シリンダ33を前進駆動して合体用アーム31を、支持軸57を中心に回転させて支持部3に接近させ、図5に示すように、アーム側連結部65を連結部25に連結させる。このとき、アーム側連結部65のエア送給口65bが連結部25のエア供給口27上に載置され、エア送給口65bとエア供給口27とを相互に接続する。
【0028】
またこのとき、支持部3のガイドロック19は、リニアガイドレール11を固定してロックした状態である。この状態で、エア導入配管67に図示しないエア供給装置からエアを導入することで、この導入したエアを、エア送給口65b,エア供給口27およびエア供給配管29を経て、ガイドロック19に送り込む。
【0029】
これにより、ガイドロック19のリニアガイドレール11に対するロックを外し、移動体13およびガイドロック19は、リニアガイドレール11上を移動可能となる。
【0030】
この状態で、外部駆動機構23のモータ45を駆動することで、ねじ棒41が回転し、ボールガイドナット43がねじ棒41に沿って移動する。これに伴いボールガイドナット43と一体の支持ブラケット53および合体用アーム31も同様に移動して、合体用アーム31に連結した支持部3も、リニアガイドレール11にガイドされて移動する。
【0031】
そして、支持部3に設けてあるワーク受け15,17を、ワークWの形状(支持部3の移動方向に沿う長さ)に合わせた位置となるように、上記したモータ45を駆動制御する。ワーク受け15,17を所定の位置に移動させたら、ガイドロック19へのエアの供給を停止し、これによりガイドロック19によるリニアガイドレール11に対するロックを行い、支持部3を上記所定の位置でロック固定する。
【0032】
支持部3をロック固定したら、外部駆動機構23の駆動シリンダ33を後退駆動させ、合体用アーム31を図1に示す状態となるよう後退させてアーム側連結部65と連結部25との連結を解除する。
【0033】
この状態で、図2に示してあるように、台車7の車体前方側の支持部1と、上記所定の位置に移動位置決めした車体後方側の支持部3とに、ワークWの下端をそれぞれ支持させる。ここで、支持部3においては、ワークWの形状に応じてワーク受け15または17を使い分ける。次に台車7は、所定の加工作業位置、例えば溶接作業位置までワークWを搬送し、ここで溶接作業を行う。
【0034】
上記した実施形態によれば、以下の効果を奏する。
【0035】
(1)ワークWを搬送支持する複数の支持部1,3のうちの少なくとも一つ(支持部3)を、他の支持部1に対して接近離反する方向に移動可能に設け、その移動させた任意の位置で固定するようにしたため、この移動可能な一つの支持部3により複数種のワークWに対応でき、各種ワーク専用の支持部を、移動方向に沿って複数設ける必要がなく、これにより溶接作業などの加工作業時での支持部3が邪魔になるという課題を解消でき、例えば溶接ガンの進入が容易となり、加工作業を容易に行うことができる。
【0036】
(2)新たに車種が追加されて別形状のワークを支持する場合でも、支持部3をそれに合わせて移動させればよいので、ワーク搬送支持装置の改造が不要である。
【0037】
(3)支持部3の位置切替えは、外部駆動機構23により行っているので、台車7毎の切替機構が不要であり、台車7は簡素化した構造となり、設備費の増大を防止できる。
【0038】
(4)外部駆動機構23を支持部3の連結部25に連結したときに、エア供給口25とエア送給口65bとが接続されるので、ガイドロック19のロックを解除する際のエア供給のための専用の接続時間が不要となり、作業時間の短縮化を図ることができる。
【0039】
(5)支持部3には、ワーク形状に合わせて複数のワーク受け15,17を設けているので、汎用化したワーク搬送支持装置となる。
