Abstract
Description
本願は、2009年2月16日に日本国に出願された特願2009-032909号に基づいて優先権を主張し、その内容をここに援用する。
上述のようなアニール装置は、炉体の入口開口部及び出口開口部を介して炉体内部に挿通されるシートを加熱してアニール処理することによって、連続的に供給されるシートを連続的に処理可能とされている。
更に、例えば、メンテナンスは、シートが炉体に挿通されていない状態で行われるために、メンテナンスの終了後に、シートを再度炉体の内部に挿通させる必要がある。
したがって、従来のアニール装置は、炉体内部に配置されると共にシートの一部を把持するベルト部と、前記ベルト部を回転走行させる駆動部とを備える搬送装置が設置されている。
したがって、従来のアニール装置においては、シートを把持して搬送するベルト部を備える搬送装置の寿命が短いことが問題視されている。
したがって、本発明によれば、搬送装置が高温環境に晒されることを防止し、搬送装置の寿命を長期化することが可能となる。
これらの図に示すように、本実施形態のアニール装置1は、炉体2と、搬送ローラ3と、ヒータ4と、昇降装置5と、搬送装置6とを備えている。
つまり、本実施形態のアニール装置1は、炉体2の内部を露出可能とすると共に入口開口2a及び出口開口2bを開口可能とされた蓋部2cを備える炉体2を備えている。
また、蓋部2cが嵌合される炉体2の基部2dは、シートSの搬送方向から見て、凹部2d1を備える凹形状とされている。この凹部2d1の深さ距離は、突出部2c2の高さ距離よりも長く設定されている。
更に、蓋部2cの突出部2c2が基部2dの凹部2d1に挿入されるように基部2dに蓋部2cが嵌合されることによって、蓋部2cと基部2dとによって囲まれた領域が入口開口2a及び出口開口2bとなる。
また、蓋部2cには、図3の平面断面図に示すように、蓋部2cと基部2dとが嵌合された場合に蓋部2cと基部2dとの隙間Aに介在されるパッキン7(シール部材)が固定されている。このパッキン7は、隙間Aから炉体2内部の高温ガスが炉体2の外部に漏出することを抑制するものであり、蓋部2cの取り付け及び取り外しを阻害しないように伸縮性にある材料によって形成されている。
なお、パッキン7は、蓋部2cに固定されずに基部2dに固定されていても良い。また、蓋部2cの取り付け及び取り外しの際に取り外し可能とされていても良い。
なお、カバー部材8は、基部2dに固定されずに、蓋部2cに固定されていても良い。また、蓋部2cの取り付け及び取り外しの際に取り外し可能とされていても良い。
ヒータ4は、炉体2の内部に配置されており、炉体2の内部を通過するシートSを加熱する。
この昇降装置5は、例えば、油圧シリンダを備える昇降装置として用いることができる。
なお、シートSは、例えば炉体2の上流側において切断され、この状態でシートSを搬送させることによって炉体2の外部に取り出される。
より詳細には、ゴムベルト6aに形成された切込部6a1に作業者がシートSの端部近傍を挿し込むことによってゴムベルト6aにシートSを把持させる。
なお、ゴムベルト6aは、駆動ローラ6b及びテンションローラ6cが設置された位置(本実施形態においてはゴムベルト6aの下側位置)をシートSが通過しない方向に回転走行される。
この際、本実施形態のアニール装置1では、蓋部2cが取り外されることによって、炉体2の内部が露出されている。さらに、入口開口2a及び出口開口2bが上方に向けて開口されている。従って、作業者は、容易に炉体2の内部にシートSを収容することが可能となる。
この結果、蓋部2cと基部2dとの間に入口開口2a及び出口開口2bが形成され、シートSが入口開口2a及び出口開口2bを介して炉体2の内部を挿通する状態が作り出される。
また、シートSの端部が、炉体2の下流側に配置された不図示の駆動ローラ等に巻回されて引かれることによってシートSが再び搬送可能となる。
従って、炉体2内部からの放熱量を減少させて、本実施形態のアニール装置1における熱効率が向上される。
したがって、本実施形態のアニール装置1によれば、搬送装置6が高温環境に晒されることを防止し、搬送装置6の寿命を長期化することが可能となる。
したがって、本実施形態のアニール装置1によれば、高温環境への対策としてベルトとしてチェーンベルトを用いていた搬送装置と比較して、搬送装置6の取扱性が向上する。
しかしながら、本発明はこれに限定されるものではなく、例えば蓋部2cを平板状に形成することも可能である。
しかしながら、本発明はこれに限定されるものではなく、搬送装置6のベルトとしてチェーンベルトを用いることも可能である。
したがって、本発明によれば、搬送装置が高温環境に晒されることを防止し、搬送装置の寿命を長期化することが可能となる。
