Description

【０００１】
【発明の属する技術分野】
本発明は、材料の切断、切削等の際に用いられる集塵装置、加工装置及び集塵方法に関する。
【０００２】
【背景の技術】
一般に、切断装置や切削装置等の加工装置により被加工物を切断或いは切削した際には、被加工物の加工屑が大量に発生し、飛散する。この加工屑により作業者が影響を受けるのを防止するためや、加工装置の周辺が加工屑により汚れるのを防止するために、加工装置に集塵機構が設けられている。また、加工装置によって被加工物を切断或いは切削する際には、加工装置の加工刃に対して被加工物を移動させるか、逆に被加工物を固定して加工刃を移動させることになる。
【０００３】
加工刃が移動しない場合には、固定的に集塵機構を設ければよいが、加工刃が長い距離を移動する場合には、加工屑を吸引して集塵する際に、加工刃側にフレキシブルホース等を接続することになる。この場合に、加工刃の移動に伴い、フレキシブルホースが動くことになり作業の邪魔になったり、加工装置の占有スペースが広くなって、スペース効率を悪化させる。そこで、例えば、加工装置の集塵機構においては、移動自在な切断機の切断刃の真上に切断粉集塵用フードを配し、この集塵用フードと工場の集塵機に連結している固定配管との間をフレキシブルホースで接続し、かつ、フレキシブルホースを、集塵用フードの移動に備えて、その中央部近辺を高く吊り上げておくものがあった。これにより、床上でフレキシブルホースが動き回ることがなくなるが、切断機の上方でたるんだ状態のフレキシブルホースが動くことにより、切断機の上方で大きなスペースが必要となるといった問題があった。
【０００４】
これを解決するため、例えば、特開平１１−２６８０２４号公報に開示されているＡＬＣ（軽量気泡コンクリート）パネルの加工装置に設けられている集塵機構は、集塵用フードと集塵機に連結された固定配管との間を、水平方向に伸縮可能に懸吊された蛇腹ホースで接続し、かつ、加工刃の移動方向に沿って蛇腹ホースを配置するものとしている。これによれば、加工刃の移動範囲を蛇腹ホースが伸縮移動するだけなので、実質的に必要なスペースは、縮んだ状態の蛇腹ホースのスペースとなり、スペース効率が高い。
【０００５】
【発明が解決しようとする課題】
しかしながら、比較的長い部材の切断或いは切削を行う際には、蛇腹ホースの伸縮性にも限界があり、それに応じて蛇腹ホースも縮んだ状態で長いものを使用しなくてはならないので、占有スペースを多くとる可能性がある。
【０００６】
そこで、本発明者は、材料の切断、切削等の作業スペースを十分に確保し、これら作業を円滑に行うことができる集塵装置、加工装置及び集塵方法を提供する。
【０００７】
【課題を解決するための手段】
請求項１記載の発明は、例えば、図１〜３に示すように、材料の切断、切削等の加工屑を排出する加工を行うとともに、移動自在な加工手段１と、該加工手段１と一体に移動するように設けられるとともに、加工屑の飛散を防止する防塵部（防塵カバー）３とを備えた加工装置Ｂから加工屑を集塵する集塵装置Ａであって、前記防塵部３に接続されて該防塵部３と一体に往復するように周回移動可能な環状の無端ベルト４ｂを有するベルトコンベア状の周回ベルト部４を備え、前記周回ベルト部４には、前記無端ベルト４ｂの左右の開口する部分をそれぞれ覆う閉塞部４ｄが設けられ、前記周回ベルト部４の内部が前記無端ベルト４ｂと前記閉塞部４ｄとにより覆われた状態となっており、前記防塵部３が受台６を介して前記無端ベルト４ｂに接続され、前記受台６の前記防塵部３と前記無端ベルト４ｂとの接続部分には貫通孔６ａが形成され、前記無端ベルト４ｂの前記防塵部３に接続された部分には、該防塵部３内の加工屑を前記無端ベルト４ｂと前記閉塞部４ｄとに囲まれた周回ベルト部４の内部に移動させるように防塵部３内に連通される連通孔４ｃが形成され、前記周回ベルト部４内から加工屑を吸引して集塵する吸引手段５を備えることを特徴とする。
【０００８】
請求項１記載の発明によれば、防塵部３内の加工屑が、受台６の貫通孔６ａと防塵部３内に連通される連通孔４ｃとを通って周回ベルト部４の内部に移動し、周回ベルト部４内から加工屑を吸引して集塵する。加工屑を集塵する際、吸引手段５として、周回ベルト部４に吸引口５ａを設け、吸引用ホース５ｂを接続しても、この吸引用ホース５ｂは加工手段１の移動に伴い、動いたりはしない。従って、材料の切断、切削等のための加工刃１ａ付近に、前述したフレキシブルホース、蛇腹ホース等を設ける必要がないので、この付近での作業スペースが確保され、作業の邪魔になることはない。さらに、周回ベルト部４は、加工手段１の略移動範囲内に納めることができ、集塵装置Ａが作業の邪魔になることはない。これにより、円滑な切断、切削等の加工作業を行うことができる。
加えて、請求項１記載の発明によれば、周回ベルト部４には、環状の無端ベルト４ｂの左右の開口する部分をそれぞれ覆う閉塞部４ｄが設けられているので、周回ベルト部４の内部の加工屑は、閉塞部４ｄにより、飛散したり、或いは無端ベルト４ｂ下側の部分の上面の左右からこぼれ落ちたりすることがなく集塵効率が向上する。
【０００９】
請求項２記載の発明は、例えば図１〜３に示すように、請求項１記載の集塵装置Ａにおいて、前記周回ベルト部４は、前記無端ベルト４ｂの上側となる部分の上面側に前記防塵部３が接続され、該防塵部３内の加工屑が前記受台６の貫通孔６ａと前記無端ベルト４ｂの連通孔４ｃとを通って前記無端ベルト４ｂの下側となる部分の上面に落下するようになっていることを特徴とする。
【００１０】
請求項２記載の発明によれば、防塵部３内の加工屑が受台６の貫通孔６ａと無端ベルト４ｂの連通孔４ｃとを通って、無端ベルト４ｂの下側となる部分の上面に落下し、吸引手段５により吸引され、集塵される。この場合、常に吸引手段５を作用させ、吸引しなくても、ある程度の加工屑が周回ベルト部４内に蓄積してから吸引するようにしてもよいので、電気代等の作業コストの節減を図ることができる。また、加工屑が無端ベルト４ｂの下側となる部分の上面で往復運動することになり、吸引手段５の吸引口５ａが固定されていても、周回ベルト部４内部の加工屑を確実に吸引できる。
【００１１】
請求項３記載の発明は、例えば図１〜３に示すように、請求項１または２記載の集塵装置Ａにおいて、前記吸引手段５の吸引口５ａが、前記周回ベルト部４の内部の前後端部の少なくとも一方の端部に配置されていることを特徴とする。
【００１２】
請求項３記載の発明によれば、請求項２の構成による無端ベルト４ｂの下側となる部分の上面に落下した加工屑は、無端ベルト４ｂの往復運動により、最終的には、周回ベルト部３の内部の前後端部を往復移動するので、前後端部の少なくとも一方の端部に配置された吸引手段５の吸引口５ａから確実に吸引できるので集塵効率は向上する。
【００１５】
請求項４記載の発明は、例えば図１〜３に示すように、材料の切断、切削等の加工屑を排出する加工を行うとともに、移動自在な加工手段１と、該加工手段１と一体に移動するように設けられるとともに、加工屑の飛散を防止する防塵部３とを備えた加工装置Ｂであって、前記防塵部３に接続されて該防塵部３と一体に往復移動可能な環状の無端ベルト４ｂを有するベルトコンベア状の周回ベルト部４を備え、前記周回ベルト部４には、前記無端ベルト４ｂの左右の開口する部分をそれぞれ覆う閉塞部４ｄが設けられ、前記周回ベルト部４の内部が前記無端ベルト４ｂと前記閉塞部４ｄとにより覆われた状態となっており、前記防塵部３が受台６を介して前記無端ベルト４ｂに接続され、前記受台６の前記防塵部３と前記無端ベルト４ｂとの接続部分には貫通孔６ａが形成され、該無端ベルト４ｂの前記防塵部３に接続された部分には、防塵部３内の加工屑を前記無端ベルト４ｂと前記閉塞部４ｄとに囲まれた周回ベルト部４の内部に移動させるように防塵部３内に連通される連通孔４ｃが形成され、前記周回ベルト部４内から加工屑を吸引して集塵する吸引手段５を備えることを特徴とする。
【００１６】
請求項４記載の発明によれば、請求項１に記載の集塵装置Ａと同様の集塵効果を奏する加工装置Ｂを提供することができる。
【００１７】
請求項５記載の発明は、例えば図１〜３に示すように、請求項１〜３のいずれか一つに記載の集塵装置Ａもしくは請求項４記載の加工装置Ｂを用いた集塵方法であって、材料加工時に前記加工手段１とともに前記防塵部３が移動した際に、前記無端ベルト４ｂが前記防塵部３とともに往復するように周回移動するとともに、加工により生じた加工屑が前記防塵部３から前記受台６の貫通孔６ａと前記無端ベルト４ｂの連通孔４ｃとを通って、周回ベルト部４の内部に至り、吸引手段５に吸引されて集塵されることを特徴とする。
【００１８】
請求項５記載の発明によれば、請求項１〜３のいずれか一つもしくは請求項４の発明と同様の効果を奏する。
【００１９】
【発明の実施の形態】
以下、本発明の集塵装置、加工装置及び集塵方法に係る実施の形態について図面を参照して説明する。なお、建物の壁構造として、壁パネルのような壁材の外側にサイディングのような外装材が取り付けられるが、本実施の形態に係る加工装置Ｂは、この外装材を切断するとともに、切断側の側縁に実を形成する切削加工を施すのに用いられる装置である。
【００２０】
まず、集塵装置Ａ、加工装置Ｂの構成を説明する。図１〜３に示すように、加工装置Ｂは、外装材の切断、切削加工を行う加工手段１と、加工手段を移動させる移動手段２と、加工屑の飛散を防止する防塵カバー（集塵部）３と、を備えている。また、加工装置Ｂから加工屑を集塵する集塵装置Ａは、防塵カバー３に接続されているベルトコンベア状の周回ベルト部４と、周回ベルト部４から加工屑を集塵する吸引手段５と、を備えている。なお、図１においては、移動手段２と周回ベルト部４の後述する無端ベルト４ｂとの図示を省略している。
【００２１】
加工手段１は、円盤状の加工刃１ａと、この加工刃１ａをその中心軸の回りに回転させる電動モータ１ｂと、加工手段１の底面に設けられた四つの車輪１ｃと、後述する移動手段に接続される棒状の接続部１ｄと、からなるものである。加工刃１ａは、加工手段１に設けられた移動機構（図示略）により、上下に移動可能となっている（図２参照）。外装材に切断及び切削加工を施す際には、電動モータ１ｂを駆動させ、加工刃１ａを回転させるとともに、防塵カバー３の上方に突出するような状態とし、外装材の切断、切削加工を行わせる。
【００２２】
移動手段２は、図３に示すように、前述した加工手段１を支持する板状の支持台２ａと、支持台２ａの上部に後述する周回ベルト部４と平行に配置される二本の角状の支持棒２ｂとを備え、二本の支持棒２ｂの上部には、案内レール２ｃがそれぞれ設けられている。この二本の案内レール２ｃに、前述した加工手段１の４つの車輪１ｃを載置させ、案内レール２ｃに沿わせて加工手段１を前後に移動させるようになっている。
【００２３】
また、移動手段２の支持台２ａの上部には、加工手段１を移動させるための電動モータ２ｄが備えられており、この電動モータ２ｄには、二本の支持棒２ｂ間に設けられたチェーンベルト２ｅが図示しないスプロケットを介してつながれている。ここで、チェーンベルト２ｅには、前述した加工手段１の接続部１ｄが接続されている。従って、電動モータ２ｄを駆動させることによりチェーンベルト２ｅが周回するが、このチェーンベルト２ｅの周回に伴い、接続部１ｄによって移動手段２に接続された加工手段１は、案内レール２ｃに沿って前後に往復移動可能なように移動自在となる。
【００２４】
防塵カバー３は、前述した加工手段１と一体になるように設けられるとともに、加工刃１ａの上方を除く部分を覆うように形成されており、加工刃１ａによって、外装材が切断、切削された際の加工屑の飛散を防止する。
【００２５】
周回ベルト部４は、前後に配置された回転ローラ４ａ間に掛け渡された環状の無端ベルト４ｂを有するベルトコンベア状のものであり、支持台２ａの加工刃１ａ側の側部に支持される細長い梯子状のフレーム部４ｅと、このフレーム部４ｅの前後端部のそれぞれに回転自在に支持される前記二つの回転ローラ４ａと、これら回転ローラ４ａに掛け渡される前記無端ベルト４ｂとを備えている。そして、前述した集塵カバー３が無端ベルト４ｂに、皿状の受台６を介して接続されている。受台６の防塵カバー３に接続された部分には貫通孔６ａが形成され、さらに、受台６下部に配置する無端ベルト４ｂの上側となる部分にも、貫通孔６ａと略同じ大きさで、かつ、防塵カバー３に連通される連通孔４ｃが形成されている。すなわち、無端ベルト４ｂの上側となる部分に受台６を介して防塵カバー３が接続され、防塵カバー３内の加工屑は、受台６の貫通孔６ａを通り、さらに無端ベルト４ｂの上側となる部分に形成された連通孔４ｃを通って、無端ベルト４ｂの下側となる部分の上面に落下するようになっている。
【００２６】
さらに、周回ベルト部４のフレーム部４ｅの左右側部には、無端ベルト４ｂの左右の開口する部分をそれぞれ覆う閉塞部４ｄが設けられている。従って、防塵カバー３から落下してきた加工屑は、周回ベルト部４の内部で、上下の無端ベルト４ｂと左右の閉塞部４ｄとにより覆われた状態となる。これにより、周回ベルト部４内部の加工屑は、閉塞部４ｄにより、周回ベルト部４内で飛散したり、無端ベルト４ｄの下側の上面の左右からこぼれ落ちたりすることはなく、後述する吸引手段５により効率良く集塵される。
【００２７】
吸引手段５の吸引口５ａは、周回ベルト部４の内部の前後端部の少なくとも一方の端部に配置されている。本実施の形態においては、図１または図２中に示す閉塞部４ｄの左端に吸引口５ａが設けられており、吸引口５ａには、加工屑を吸引するための吸引用ホース５ｂが接続されている。従って、周回ベルト部４内の加工屑は、この吸引口５ａから吸引用ホース５ｂを通って集塵されるようになっている。
【００２８】
次に、前述した集塵装置Ａ、加工装置Ｂを用いた集塵方法を説明する。まず、加工手段１の加工刃１ａの上方に、加工を施したい所望の位置に外装材が配置するように、図示しない固定手段により外装材を正確に固定する。そして、加工手段１の電動モータ１ｂを駆動させ、加工刃１ａを回転させるとともに、加工刃１ａを防塵カバー３の上方に突出する状態となるように加工刃１ａを上方に移動させ、外装材の切断、切削作業を開始させる。また、外装材の切断、切削作業と略同時に移動手段の電動モータ２ｄを駆動させ、加工手段１を前方に移動させる。
【００２９】
加工手段１の移動に伴い、加工手段１と一体に設けられている防塵カバー３も前方に移動する。この場合、防塵カバー３に接続されている周回ベルト部４の無端ベルト４ｂも防塵カバー３の移動に連動するように、前後に配置された回転ローラ４ａを二つの軸として周回移動する。
【００３０】
加工刃１ａの回転、及び加工手段１の移動に伴い、固定されている外装材は切断されるとともに、切断側の側縁に実を形成する切削加工が施され、加工屑が発生し、この加工屑は防塵カバー３内に入っていく。そして、防塵カバー３内の加工屑は、防塵カバー３に接続された受台６の貫通孔６ａ、及び周回ベルト部４に形成された連通孔４ｃを通って、無端ベルト４ｂの下側となる部分の上面に落下していく。この場合、加工手段１は前方に移動しているので、無端ベルト４ｂの下側となる部分は後方に移動するように周回している。従って、落下してきた加工屑は、周回ベルト部４の内部の後方の端部に寄せ集められるように移動する。
【００３１】
そして、この加工屑は、周回ベルト部４の後方に設けられている吸引口５ａ付近に達すると、吸引用ホース５ｂから集塵される。なお、無端ベルト４ｂの下側となる部分の上面に落下した加工屑は、最終的に、無端ベルト４ｂの正逆の周回移動に伴い、周回ベルト部４の前後の端部を往復移動する。従って、常に吸引手段を作用させ、この加工屑を吸引して集塵する必要はなく、ある程度周回ベルト部４内に加工屑が蓄積してから、吸引するようにしてもよい。これにより、吸引手段５を作用させるための電気代等を節減することができる。また、吸引手段５の吸引口５ａが固定されていても、加工屑は無端ベルト４ｂの周回移動により、この吸引口５ａ付近に移動するので、確実に吸引することができる。
【００３２】
切断、切削作業後においては、切断、切削加工された外装材を取り外し、前方に移動した加工手段１を後方に戻すように移動させる。そしてまた、前述したような切断、切削作業を繰り返して行うようになる。なお、一度の切断、切削作業で集塵されなかった加工屑は、周回ベルト部４内部で、無端ベルト４ｂの下側となる部分の上面で往復することになり、いずれにしても、吸引口５ａ付近に移動するので確実に集塵される。
【００３３】
以上、本実施の形態に係る集塵装置Ａ、加工装置Ｂ及び集塵方法によれば、防塵カバー３内の加工屑が、受台６の貫通孔６ａ、及び周回ベルト部４の連通孔４ｃを通って周回ベルト部４の内部に移動し、周回ベルト部４内から吸引手段５により加工屑を吸引して集塵する。加工屑を集塵する際、吸引手段５として、周回ベルト部４に吸引口５ａを設け、吸引用ホース５ｂを接続したが、この吸引用ホース５ｂは加工手段１の移動に伴い、動いたりはしない。従って、外装材の切断、切削等のための加工刃１ａ付近に、従来例に示した加工装置のフレキシブルホース、蛇腹ホース等を設ける必要がないので、この付近での作業スペースが確保され、切断、切削作業の邪魔になることはない。さらに、周回ベルト部４は、加工手段１の略移動範囲内に納めることができ、集塵装置Ａが作業の邪魔になることはない。これにより、切断、切削作業を円滑に行うことができる。
【００３４】
【発明の効果】
請求項１記載の発明によれば、材料の切断、切削等のための加工刃付近に、従来の切断機付近に備えられていたフレキシブルホース、蛇腹ホース等を設ける必要がないので、この付近での作業スペースが確保され、作業の邪魔になることはない。さらに、周回ベルト部は、加工手段の略移動範囲内に納めることができ、集塵装置が作業の邪魔になることもなく、円滑な切断、切削等の加工作業を行うことができる。
加えて、請求項１記載の発明によれば、周回ベルト部には、閉塞部が設けられているので、周回ベルト部の内部の加工屑は、閉塞部により、飛散したり、或いは無端ベルト下側の部分の上面の左右からこぼれ落ちたりすることがなく集塵効率が向上する。
【００３５】
請求項２記載の発明によれば、常に吸引手段を作用させ、被加工物の加工屑を吸引しなくても、ある程度の加工屑が蓄積してから吸引するようにしてもよいので、電気代等の作業コストの節減を図ることができる。また、加工屑が無端ベルトの下側となる部分の上面で往復運動することになり、吸引手段の吸引口が固定されていても、周回ベルト部内部の加工屑を確実に吸引できる。
【００３６】
請求項３記載の発明によれば、加工屑は、周回ベルト部の内部の前後端部の少なくとも一方の端部に配置された吸引手段の吸引口から確実に吸引できるので集塵効率は向上する。

BACKGROUND OF THE INVENTION
The present invention relates to a dust collection device, a processing device, and a dust collection method that are used when cutting or cutting a material.
[0002]
[Background technology]
In general, when a workpiece is cut or cut by a processing device such as a cutting device or a cutting device, a large amount of processing waste of the workpiece is generated and scattered. In order to prevent an operator from being affected by the processing scraps and to prevent the periphery of the processing apparatus from being contaminated by the processing scraps, a dust collecting mechanism is provided in the processing apparatus. Further, when the workpiece is cut or cut by the processing device, the workpiece is moved with respect to the processing blade of the processing device, or conversely, the workpiece is fixed and moved. .
[0003]
If the processing blade does not move, a fixed dust collection mechanism may be provided. However, if the processing blade moves over a long distance, it is flexible on the processing blade side when suctioning and collecting the processing waste. Hose etc. will be connected. In this case, along with the movement of the processing blade, the flexible hose moves and interferes with the work, or the space occupied by the processing apparatus becomes wide, and the space efficiency is deteriorated. Therefore, for example, in a dust collection mechanism of a processing apparatus, a fixed dust pipe is connected to the dust collection hood and a factory dust collector by placing a cutting powder dust collection hood directly above the cutting blade of a movable cutting machine. And a flexible hose that is suspended in the vicinity of the center of the flexible hose in preparation for the movement of the dust collecting hood. As a result, the flexible hose does not move around on the floor, but there is a problem that a large space is required above the cutting machine due to the movement of the flexible hose that is slacking above the cutting machine.
[0004]
In order to solve this problem, for example, a dust collection mechanism provided in a processing apparatus for an ALC (lightweight aerated concrete) panel disclosed in Japanese Patent Application Laid-Open No. 11-268024 has a fixed structure connected to a dust collection hood and a dust collector. It connects with piping with the bellows hose suspended so that it can expand-contract horizontally, and the bellows hose shall be arrange | positioned along the moving direction of a processing blade. According to this, since the bellows hose only expands and contracts within the moving range of the processing blade, the substantially necessary space becomes the space of the bellows hose in a contracted state, and the space efficiency is high.
[0005]
[Problems to be solved by the invention]
However, when cutting or cutting relatively long members, there is a limit to the elasticity of the bellows hose, and accordingly the long bellows hose must be used in a contracted state. There is a possibility of taking a lot.
[0006]

It passes through the communication hole 4c formed in the portion to be dropped onto the upper surface of the portion on the lower side of the endless belt 4b.
[0026]
Further, on the left and right side portions of the frame portion 4e of the circulating belt portion 4, there are provided closed portions 4d that respectively cover left and right opening portions of the endless belt 4b. Therefore, the processing waste that has fallen from the dust cover 3 is covered with the upper and lower endless belts 4b and the left and right closed portions 4d inside the circulating belt portion 4. As a result, the processing scrap inside the circulating belt portion 4 is not scattered by the closing portion 4d in the circulating belt portion 4 or spills from the left and right of the lower surface of the endless belt 4d. 5 to collect dust efficiently.
[0027]
The suction port 5 a of the suction means 5 is disposed at at least one of the front and rear end portions inside the circulating belt portion 4. In the present embodiment, a suction port 5a is provided at the left end of the blocking portion 4d shown in FIG. 1 or FIG. 2, and a suction hose 5b for sucking machining waste is connected to the suction port 5a. ing. Accordingly, the processing waste in the circulating belt portion 4 is collected from the suction port 5a through the suction hose 5b.
[0028]
Next, a dust collection method using the dust collector A and the processing device B described above will be described. First, the exterior material is accurately fixed by a fixing means (not shown) so that the exterior material is disposed at a desired position to be processed above the processing blade 1a of the processing means 1. Then, the electric motor 1b of the processing means 1 is driven to rotate the processing blade 1a, and the processing blade 1a is moved upward so that the processing blade 1a protrudes above the dustproof cover 3, so that the exterior material Start cutting and cutting work. Further, the electric motor 2d of the moving means is driven substantially simultaneously with the cutting and cutting work of the exterior material, and the processing means 1 is moved forward.
[0029]
As the processing means 1 moves, the dust cover 3 provided integrally with the processing means 1 also moves forward. In this case, the endless belt 4b of the circling belt portion 4 connected to the dustproof cover 3 also rotates around the rotating rollers 4a arranged at the front and rear so as to be interlocked with the movement of the dustproof cover 3.
[0030]
Along with the rotation of the processing blade 1a and the movement of the processing means 1, the fixed exterior material is cut and cut to form a fruit on the side edge on the cutting side, and processing waste is generated. Processing waste enters the dust cover 3. And the processing waste in the dust-proof cover 3 becomes the lower side of the endless belt 4b through the through-hole 6a of the receiving base 6 connected to the dust-proof cover 3 and the communication hole 4c formed in the circulation belt part 4. It falls to the upper surface of the part. In this case, since the processing means 1 has moved forward, the lower part of the endless belt 4b circulates so as to move backward. Accordingly, the processing scraps that have fallen move so as to be collected at the rear end of the inside of the circulating belt portion 4.
[0031]
Then, when the processed waste reaches the vicinity of the suction port 5a provided behind the circulating belt portion 4, the dust is collected from the suction hose 5b. In addition, the processing waste dropped on the upper surface of the lower portion of the endless belt 4b finally reciprocates the front and rear end portions of the circulating belt portion 4 as the endless belt 4b rotates in the forward and reverse directions. Accordingly, it is not always necessary to operate the suction means to suck and collect the processing waste, and the processing waste may be sucked after it accumulates in the circumferential belt portion 4 to some extent. Thereby, the electricity bill etc. for operating the suction means 5 can be reduced. Further, even if the suction port 5a of the suction means 5 is fixed, the machining waste moves to the vicinity of the suction port 5a by the circumferential movement of the endless belt 4b, so that it can be reliably sucked.
[0032]
After the cutting and cutting work, the cut and cut exterior material is removed, and the processing means 1 moved forward is moved back. In addition, the cutting and cutting operations as described above are repeated. In addition, the processing waste that has not been collected by one cutting and cutting operation reciprocates on the upper surface of the lower portion of the endless belt 4b inside the circulating belt portion 4, and in any case, the suction port Since it moves to the vicinity of 5a, it is surely collected.
[0033]
As mentioned above, according to the dust collector A, the processing apparatus B, and the dust collection method which concern on this Embodiment, the processing waste in the dust-proof cover 3 is the through-hole 6a of the receiving stand 6, and the communication hole 4c of the circulation belt part 4. FIG. It passes through the inside of the circulating belt part 4 and sucks the processing waste from the circulating belt part 4 by the suction means 5 to collect the dust. When collecting the processing waste, the suction belt 5 is provided with a suction port 5a and a suction hose 5b is connected as the suction means 5, and the suction hose 5b moves as the processing means 1 moves. do not do. Accordingly, there is no need to provide the flexible hose, bellows hose, etc. of the processing apparatus shown in the conventional example near the processing blade 1a for cutting or cutting the exterior material, so that a working space in this vicinity is secured and the cutting is performed. It won't get in the way of cutting work.
