Description

【０００１】
【発明の属する技術分野】
本発明は、平板および波板が重ね合わせて巻回されて成る排ガス浄化用ハニカム構造体を製造するための製造装置に関し、特に、金属製の平板および金属製の波板を相互に接合するために、ろう材およびバインダーを含むスラリーを、巻回前の波板に塗布するようにした排ガス浄化用ハニカム構造体の製造装置の改良に関する。
【０００２】
【従来の技術】
従来、かかる装置は、たとえば特許第２７０９７８９号公報等で既に知られている。
【０００３】
【発明が解決しようとする課題】
上記従来のものでは、ろう材およびバインダーを含むスラリーを、波板に対向させて配置した複数のノズルで波板の頂部に供給するようにしているが、波板の頂部にノズルでスラリーを正確に供給することは難しい。
【０００４】
本発明は、かかる事情に鑑みてなされたものであり、波板の両面の頂部にスラリーを正確にかつスピーディに供給し得るようにした排ガス浄化用ハニカム構造体の製造装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の発明は、金属製の平板および金属製の波板が重ね合わせて巻回されて成る排ガス浄化用ハニカム構造体を製造するための製造装置であって、前記平板および波板を重ね合わせて巻回する巻回手段と、該巻回手段に供給される前の前記波板の両面に噛合するとともに該波板の前記巻回手段側への移動に同期して回転する少なくとも一対のギヤと、前記波板の両面の頂部にろう材およびバインダーを含むスラリーを塗布すべく前記各ギヤの歯底部に前記スラリーを供給するスラリー供給手段とを備えることを特徴とする。
【０００６】
このような請求項１記載の発明の構成によれば、波板の両面に噛合するとともに該波板の移動に同期して回転する少なくとも一対のギヤの歯底部にスラリーが供給されるので、スラリーが供給された前記歯底部に波板の頂部が噛み込んだときにスラリーが波板の頂部に付着することになり、波板の両面の頂部へのスラリーの正確かつスピーディな供給が可能となる。
【０００７】
また請求項２記載の発明は、上記請求項１記載の発明の構成に加えて、前記スラリー供給手段は、加圧された前記スラリーを導くスラリー通路を内部に形成して円筒状に形成されるとともに前記ギヤを回転自在に支承する筒軸と、対をなす前記ギヤが前記波板を相互間に挟む位置に対応して前記筒軸の側壁に設けられて前記スラリー通路に内端を連通させた連通孔と、前記歯底部に外端を開口させるとともに内端を前記ギヤの内周面に開口させるようにして前記ギヤに設けられるスラリー供給孔とで構成され、前記スラリー供給孔は、前記ギヤの回転に応じて各スラリー供給孔の１つの内端を前記連通孔に連通させ得る位置で前記ギヤに設けられることを特徴とする。
【０００８】
このような請求項２記載の発明の構成によれば、スラリー供給孔の１つがギヤの回転に応じて連通孔に内端を連通させ得る位置に達したときに、スラリー通路から１つのスラリー供給孔に連通孔を介してスラリーが供給されるものであり、連通孔が、対をなす前記ギヤで前記波板を相互間に挟む位置に対応して筒軸の側壁に設けらるものであるので、スラリーを過不足なく適切な量だけ波板の頂部に供給することができる。
【０００９】
請求項３記載の発明は、上記請求項１記載の発明の構成に加えて、前記スラリー供給手段は、前記ギヤ外から前記歯底部に前記スラリーを供給可能に構成されることを特徴とし、かかる構成によれば、ギヤの内部構成を単純化しつつスラリーをギヤの歯底部に供給することができる。
【００１０】
請求項４記載の発明は、上記請求項１〜３のいずれかに記載の発明の構成に加えて、前記ギヤの歯底部に、スラリーを溜める凹部がそれぞれ形成されることを特徴とし、かかる構成によれば、スラリーが供給された歯底部に波板の頂部が噛み込んだときに波板の頂部を比較的大きな面積でスラリーに接触させ、波板の両面の頂部にスラリーを確実に付着させることができる。
【００１１】
請求項５記載の発明は、上記請求項１〜４のいずれかに記載の発明の構成に加えて、前記波板側に突出した突き出し部が、前記ギヤの歯底部にそれぞれ設けられることを特徴とし、かかる構成によれば、スラリーが供給された歯底部に波板の頂部が噛み込んだときに波板の頂部へのスラリーの接触圧を大きくし、波板の両面の頂部にスラリーを確実に付着させることができる。
【００１２】
請求項６記載の発明は、上記請求項１〜５のいずれかに記載の発明の構成に加えて、前記スラリー供給手段は、前記ギヤが外周に備える複数の歯底部のうち選択された歯底部にスラリーを供給可能に構成されることを特徴とし、かかる構成によれば、波板および平板が、波板の頂部毎に接合されるのではなく、１または複数の頂部を相互間にあけた部分で波板の頂部が平板に接合されることになるので、高温の排ガスがハニカム構造体を流通する際の熱応力を緩和しつつスラリーの消費量を節約することができる。
【００１３】
さらに請求項７記載の発明は、上記請求項１〜６のいずれかに記載の発明の構成に加えて、前記スラリー供給手段が、前記ギヤの回転軸線方向に間隔をあけた複数箇所で前記歯底部にスラリーを供給可能に構成されることを特徴とし、かかる構成によれば、スラリーの消費量を抑えつつ、波板および平板の接合をより確実なものとすることができる。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を、添付の図面に示した本発明の実施例に基づいて説明する。
【００１５】
図１〜図５は本発明の第１実施例を示すものであり、図１は排ガス浄化器の斜視図、図２はハニカム構造体の製造装置の構成を示す図、図３は図２の要部拡大図、図４は図３の４矢視図、図５は図３の要部拡大図である。
【００１６】
先ず図１において、たとえば自動二輪車の排気系に設けられる排ガス浄化器１１は、メタル担体１２に触媒が担持されて成るものであり、メタル担体１２は、ハニカム構造体１３が金属製の筒形ケース１４に挿入されることで構成される。しかもハニカム構造体１３は、金属製の平板１５および金属製の波板１６が重ね合わせて巻回されて成るものであり、本発明に従う製造装置で製造される。
【００１７】
図２〜図４を併せて参照して、ハニカム構造体１３を製造する製造装置は、平板１５および波板１６を重ね合わせて巻回する巻回手段１７と、該巻回手段１７に供給される前の前記波板１６の両面に噛合するとともに該波板１６の前記巻回手段１７側への移動に同期して回転する少なくとも一対（この実施例では一対ずつ２組）のギヤ１８Ａ，１８Ａ…と、波板１６の両面の頂部１６ａ…にろう材およびバインダーを含むスラリー１９を塗布すべく前記ギヤ１８Ａ，１８Ａ…の歯底部１８ａ…にスラリー１９を供給するスラリー供給手段２０Ａ…とを備え、前記各ギヤ１８Ａ，１８Ａ…で挟まれる部分と、巻回手段１７との間で波板１６はアイドラー２１に巻掛けられる。
【００１８】
前記バインダーとしては、たとえば水溶性の熱硬化性液体プラスチックスを好適に用いることができる。また前記アイドラー２１としては、波板１６の一面の頂部１６ａ…に付着した前記スラリー１９に接触することを回避するために、ギヤもしくはスプロケットを用いることが望ましい。
【００１９】
スラリー供給手段２０Ａは、スラリー通路２２を内部に形成して円筒状に形成されるとともに波板１６の一面側に配置される一対のギヤ１８Ａ，１８Ａを共通に回転自在に支承する筒軸２３と、前記スラリー通路２２に加圧されたスラリー１９を供給するスラリー供給源２４と、相互に対をなす一対のギヤ１８Ａ，１８Ａが波板１６を相互間に挟む位置に対応して筒軸２３の側壁に設けられてスラリー通路２２に内端を連通させた連通孔２５と、ギヤ１８Ａの歯底部１８ａ…に外端をそれぞれ開口させるとともに内端をギヤ１８Ａの内周面に開口させるようにしてギヤ１８Ａに設けられる複数のスラリー供給孔２６，２６…とで構成される。
【００２０】
連通孔２５は、各ギヤ１８Ａ…の軸方向に沿う中央部にそれぞれ対応する複数箇所（この実施例では２箇所）で筒軸２３の側壁に設けられる。一方、スラリー供給孔２６，２６…は、ギヤ１８Ａがその外周に備える複数の歯底部１８ａ…の全てに個別に対応したものであり、ギヤ１８Ａの回転に応じて該スラリー供給孔２６，２６…の１つの内端が連通孔２５に連通するようにして、ギヤ１８Ａに設けられる。
【００２１】
図５を併せて参照して、ギヤ１８Ａがその外周に備える複数の歯底部１８ａ…の全てには、前記スラリー供給孔２６，２６…から供給されるスラリー１９を溜める凹部２７，２７…がそれぞれ形成される。
【００２２】
この第１実施例によれば、平板１５および波板１６を重ね合わせて巻回する巻回手段１７に供給される前の波板１６の両面に、該波板１６の巻回手段１７側への移動に同期して回転するようにして一対ずつ２組のギヤ１８Ａ，１８Ａ…が噛合されており、各ギヤ１８Ａ，１８Ａ…の歯底部１８ａ，１８ａ…には、ろう材およびバインダーを含むスラリー１９がスラリー供給手段２０Ａ，２０Ａで供給される。
【００２３】
したがってスラリー１９が供給された歯底部１８ａ，１８ａ…に波板１６の頂部１６ａ，１６ａ…が噛み込んだときにスラリー１９が波板１６の頂部１６ａ，１６ａ…に付着することになり、波板１６の両面の頂部１６ａ，１６ａ…へのスラリー１９の正確かつスピーディな供給が可能となる。
【００２４】
またスラリー供給手段２０Ａは、加圧されたスラリー１９を導くスラリー通路２２を内部に形成して円筒状に形成されるとともにギヤ１８Ａ，１８Ａを回転自在に支承する筒軸２３と、対をなすギヤ１８Ａ，１８Ａが波板１６を相互間に挟む位置に対応して筒軸２３の側壁に設けられてスラリー通路２２に内端を連通させた連通孔２５と、歯底部１８ａ，１８ａ…に外端を開口させるとともに内端をギヤ１８Ａの内周面に開口させるようにしてギヤ１８Ａに設けられるスラリー供給孔２６，２６…とで構成されるものであり、スラリー供給孔２６，２６…は、ギヤ１８Ａの回転に応じてスラリー供給孔２６，２６…の１つの内端を連通孔２５に連通させ得る位置でギヤ１８Ａに設けられている。
【００２５】
すなわち、スラリー供給手段２０Ａは、スラリー供給孔２６，２６…の１つがギヤ１８Ａの回転に応じて連通孔２５に内端を連通させ得る位置に達したときにスラリー通路２２からスラリー供給孔２６に連通孔２５を介してスラリー１９が供給されるように構成されるものであり、連通孔２５が、対をなすギヤ１８Ａ，１８Ａで波板１６を相互間に挟む位置に対応して筒軸２３の側壁に設けらるものであるので、スラリー１９を過不足なく適切な量だけ波板１６の頂部１６ａ，１６ａ…に供給することができる。
【００２６】
しかもギヤ１８Ａがその外周に備える複数の歯底部１８ａ…の全てに、スラリー供給孔２６，２６…から供給されるスラリー１９を溜める凹部２７，２７…が形成されているので、スラリー１９が供給された歯底部１８ａ，１８ａ…に波板１６の頂部１６ａ，１６ａ…が噛み込んだときに波板１６の頂部１６ａ，１６ａ…を比較的大きな面積でスラリー１９に接触させ、波板１６の両面の頂部１６ａ，１６ａ…にスラリー１９を確実に付着させることができる。
【００２７】
図６は本発明の第２実施例を示すものであり、巻回手段１７（第１実施例の図２参照）に供給される前の波板１６の両面には、該波板１６の前記巻回手段１７側への移動に同期して回転する少なくとも一対のギヤ１８Ｂ，１８Ｂが噛合されており、各ギヤ１８Ｂ，１８Ｂがその外周に備える複数の歯底部１８ａ…の全てには、波板１６側に突出した突き出し部２８，２８…がそれぞれ設けられる。
【００２８】
而して各ギヤ１８Ｂ，１８Ｂの歯底部１８ａ……にはスラリー供給手段２０Ａ…によりスラリー１９が供給されるものであり、スラリー供給手段２０Ａの一部を構成してギヤ１８Ｂに設けられるスラリー供給孔２６，２６…の外端は前記突き出し部２８，２８…の先端に開口される。
【００２９】
この第２実施例によれば、スラリー１９が供給された歯底部１８ａ，１８ａ…に波板１６の頂部１６ａ，１６ａ…が噛み込んだときに波板１６の頂部１６ａ，１６ａ…へのスラリー１９の接触圧を大きくし、波板１６の両面の頂部１６ａ，１６ａ…にスラリー１９を確実に付着させることができる。
【００３０】
図７は本発明の第３実施例を示すものであり、巻回手段１７（第１実施例の図２参照）に供給される前の波板１６の両面には、該波板１６の前記巻回手段１７側への移動に同期して回転する少なくとも一対のギヤ１８Ｃ，１８Ｃが噛合されており、各ギヤ１８Ｃ，１８Ｃがその外周に備える複数の歯底部１８ａ…の全てには、波板１６側に突出した突き出し部２８，２８…がそれぞれ設けられ、各突き出し部２８，２８…の先端には、スラリー供給手段２０Ａの一部を構成してギヤ１８Ｃに設けられるスラリー供給孔２６，２６…から供給されるスラリー１９を溜める凹部２７，２７…が形成される。
【００３１】
この第３実施例によれば、波板１６の頂部１６ａ，１６ａ…を比較的大きな面積でスラリー１９に接触させることができるとともに、波板１６の頂部１６ａ，１６ａ…へのスラリー１９の接触圧を大きくすることができ、波板１６の両面の頂部１６ａ，１６ａ…へのスラリー１９の付着をより確実なものとすることができる。
【００３２】
図８は本発明の第４実施例を示すものであり、巻回手段１７（第１実施例の図２参照）に供給される前の波板１６の両面には、該波板１６の前記巻回手段１７側への移動に同期して回転する少なくとも一対のギヤ１８Ｄ，１８Ｄが噛合される。
【００３３】
各ギヤ１８Ｄ，１８Ｄがその外周に備える複数の歯底部１８ａ…のうち選択された歯底部、この実施例ではギヤ１８Ｄの周方向に１つおきの歯底部１８ａ…には凹部２７…が形成されており、それらの凹部２７…にスラリー供給手段２０Ｂ…によりスラリー１９が供給される。
【００３４】
スラリー供給手段２０Ｂは、スラリー通路２２を内部に形成して円筒状に形成されるギヤ１８Ｄを回転自在に支承する筒軸２３と、相互に対をなす一対のギヤ１８Ｄ，１８Ｄが波板１６を相互間に挟む位置に対応して筒軸２３の側壁に設けられてスラリー通路２２に内端を連通させた連通孔２５と、ギヤ１８Ｄの歯底部１８ａ…の凹部２７，２７…に外端をそれぞれ開口させるとともに内端をギヤ１８Ｄの内周面に開口させるようにしてギヤ１８Ｄに設けられる複数のスラリー供給孔２６，２６…とで構成される。
【００３５】
この第４実施例によれば、波板１６の両面の各頂部１６ａ，１６ａ…のうち１つおきの頂部１６ａ，１６ａ…にスラリー１９が付着されることになり、波板１６および平板１５（第１実施例の図１および図２参照）が、波板１６の頂部１６ａ，１６ａ…毎に接合されるのではなく、１つおきの頂部１６ａ，１６ａ…が平板１５に接合されることになるので、高温の排ガスがハニカム構造体１３（図１参照）を流通する際の熱応力を緩和しつつスラリー１９の消費量を節約することができる。
【００３６】
図９および図１０は本発明の第５実施例を示すものであり、図９は図５に対応した断面図、図１０は図９の１０矢視図である。
【００３７】
巻回手段１７（第１実施例の図２参照）に供給される前の波板１６の両面には、該波板１６の前記巻回手段１７側への移動に同期して回転する少なくとも一対、この第５実施例では１対ずつ２組のギヤ１８Ｅ，１８Ｅ…が噛合される。
【００３８】
各ギヤ１８Ｅ，１８Ｅの軸線に沿う一端側で該ギヤ１８Ｅ…の周方向に１つおきの歯底部１８ａ…には凹部２７Ａ…が形成される。また各ギヤ１８Ｅ，１８Ｅの軸線に沿う他端側で、前記凹部２７Ａ…が形成されている歯底部１８ａ…に隣接する歯底部１８ａ…には凹部２７Ｂ…が形成される。
【００３９】
各ギヤ１８Ｅ…の凹部２７Ａ…，２７Ｂ…には、スラリー供給手段２０Ｃ…によりスラリー１９が供給されるものであり、該スラリー供給手段２０Ｃは、スラリー通路２２を内部に形成して円筒状に形成されるとともに波板１６の一面側に配置される一対のギヤ１８Ｅ，１８Ｅを共通に回転自在に支承する筒軸２３と、前記スラリー通路２２に加圧されたスラリー１９を供給するスラリー供給源２４と、相互に対をなす一対のギヤ１８Ｅ，１８Ｅが波板１６を相互間に挟む位置に対応して筒軸２３の側壁に設けられてスラリー通路２２に内端を連通させた一対の連通孔２５…と、ギヤ１８Ｅの歯底部１８ａ…に形成された凹部２７Ａ…，２７Ｂ…に外端をそれぞれ開口させるとともに内端をギヤ１８Ｅの内周面に開口させるようにしてギヤ１８Ｅに設けられる複数のスラリー供給孔２６，２６…とで構成される。
【００４０】
前記連通孔２５…は、ギヤ１８Ｅの軸方向に沿って間隔をあけた複数箇所、この実施例では２箇所で歯底部１８ａ…に形成された凹部２７Ａ…，２７Ｂ…に対応した位置で筒軸２３に設けられており、スラリー供給孔２６，２６…の一部は凹部２７Ａ…に外端を開口させるとともに内端をギヤ１８Ｅの内周に開口させるようにしてギヤ１８Ｅに設けられ、スラリー供給孔２６，２６…の残部は凹部２７Ｂ…に外端を開口させるとともに内端をギヤ１８Ｅの内周に開口させるようにしてギヤ１８Ｅに設けられる。
