Description

【０００１】
【発明の属する技術分野】
本発明は、使用済みのビン、缶、プラスチックボトル等の廃棄容器が収納されたビニール袋等の袋体を破袋して、前記廃棄容器から袋体を分離し、該袋体のみを外部に除去するように構成された破袋装置に用いられる破袋刃の構造に関する。
【０００２】
【従来の技術】
ごみ処理設備においては、ビニール袋等の比較的大きな破袋強度を有する袋体内にビン、缶、プラスチックボトル等の廃棄容器が入った廃棄物から廃棄容器と袋体とを分離し、該廃棄容器をリサイクルするとともに、該袋体を外部に除去するようにした破袋装置が、処理設備の一つとして設置されている。
【０００３】
かかる破袋装置に関する技術として、特開平２０００−７９３４９号、特開平１０−５６１４号、特開平８−１１９４０５号、特開平１０−２３０１８４号等の発明が提供されている。
特開平２０００−７９３４９号においては、移動部に沿って配列された複数の爪を有する無端コンベアを、その上側の移動部の移動方向先が高位に位置するように配設するとともに、爪が通過可能なスリットを有するプレートを、前記無端コンベアの上側の移動部に沿って該無端コンベアの上方に配設する一方、一端部がプレートに接し若しくは近接し、自由端側部がプレート外方に位置する堰止板を設け、該堰止板には爪が通過可能なスリットを設け、該爪を、弾性部材を有して、その爪先部にかかる抵抗に応じて移動方向と反対側に揺動可能若しくは起倒可能に構成されている。
【０００４】
また、特開平１０−５６１４号の発明においては、ケーシングの上部にごみの投入口を、下部にロータを、その下にビン等の排出口と、エアーの吹出口と、破袋したごみ袋の排出口を、排出口の回転方向後方に櫛歯状の邪魔板を設け、前記ロータは、放射状に延びる連結板と、該連結板端部に軸方向に一定間隔で固着される環状板と、周方向に一定間隔で前記環状板に突設される逆Ｖ字状の刃物を設け、ケーシングに設けたヒータ及び刃物と共にごみ袋を溶融し、引き裂いて破袋する。これにより、ごみ袋の中に入ったビン等は排出口より、破袋したごみ袋は別の排出口より排出され、刃物に付着したごみ袋は邪魔板の溝縁で擦り取られ除去される。
【０００５】
【発明が解決しようとする課題】
しかしながら、前記従来技術にあっては、次のような問題点を有している。
即ち、特開平２０００−７９３４９号においては、移動部に沿って複数の爪が配列された無端コンベアを設けた構造であるため、装置の長さが長くなって装置が大型化し、装置コストも高くなる。
また、ビンが入った袋が爪に架けられて無端コンベアの斜面を上がる際に、袋が爪から外れて無端コンベアの下方に落下して、内部のビンが割れ、回収が不能になるという事態の発生をみる。
【０００６】
また、かかる従来技術にあっては、ビンが入った袋を長尺の無端コンベアに沿って該コンベアの上端部まで運び、該上端部に対応して設けられた堰止板にて破袋し、ビンを落下させるようになっているため、ビン同士の衝突音や、ビンがコンベアの面や爪に衝突しながら落下する際の衝突音等により騒音が大きい。
【０００７】
さらには、かかる従来技術にあっては、コンベアにスラット及び取付座を介して該コンベアの移動方向に複数取り付けられた爪をコンベアによって送り該爪の先端にて袋体に切裂し、該コンベアの移動により前記爪の先端で該袋体を引き裂くように構成されていることから、いわゆる切れ味が十分でなく大きな破袋力が得られ難く、このため、袋体内からビンが確実に抜き出せず、袋体とビンとの分離がなされない事態が発生し、十分な破袋効果が得られない、
等の問題点を有している。
【０００８】
また特開平１０−５６１４号の発明においては、１つのロータの回転に従い、該ロータの外周に円周方向に沿って取り付けられた逆Ｖ字状の刃物とヒータとによってビンが入った袋を溶融、破袋し、刃物に付着した袋を邪魔板の溝縁で擦り取って除去するようになっているため、袋が刃物によって切裂、引き裂き作用を受ける期間が短く、ヒータとによる袋の溶融作用が付加されても袋とビンとの分離が充分になされず、ビン側に袋の残骸が付着し、ビンの回収作用が充分になされないという問題点がある。
【０００９】
尚、特開平８−１１９４０５号はシーズヒータによりごみ袋を溶融して裂くようにしたもので、シーズヒータにごみ袋が溶着したり可燃しやすいごみにあっては誤って可燃する恐れもある。
【００１０】
特開平１０−２３０１８４号もコンベアにより搬送されてくるごみ袋の進行を先端に刃板を有するキャッチャで妨げてごみ袋の破開を行うもので、キャッチャ先端に袋の破片が付着しやすく保守管理が煩雑化する。
【００１１】
本発明はかかる従来技術の課題に鑑み、ヒータ等の格別な袋体の溶融手段を不要とした簡単な構造で以って袋体の破袋力が増大され、廃棄容器と袋体との分離を効率的かつ確実に行うことができるとともに、破袋及び除袋騒音を低減し得る破袋刃構造を提供することを目的とする。
【００１２】
【課題を解決するための手段】
本発明はかかる課題を解決するため、請求項１記載の発明として、回転駆動されるロータ若しくは周回駆動されるベルト体からなる移動体周面上に取り付けられた破袋刃であって、該移動体上の破袋空間に供給された、ビン、缶、プラスチックボトル等の廃棄容器が入った袋体を破袋して、前記廃棄容器から袋体を分離可能な破袋刃において、
前記破袋刃は、前記移動体に一端が固定され片持ち状態で延在する板ばね状支持体と、該支持体の自由端側に、前記移動体の移動により前記袋体に切裂せしめる刃先を有し、移動体の移動方向に沿う方向と平行に設けられた縦刃とを備え、前記支持体を一端が固定され他端の自由端側が縦刃起立方向に揺動可能に構成し、該支持体の自由端側に前記縦刃を設けてなることを特徴とする。
そして好ましくは、後記第２発明に詳細に示すように、前記縦刃は、前記支持体に、前記移動体の移動方向に複数個列設してなるのがよい。
そして更に好ましくは、前記支持体の自由端側に前記縦刃とともに、該縦刃とほぼ直角方向に延設する複数の横刃を設けてなるのがよい。
又前記縦刃は、支持体を移動体に固定する固定部分に対し、前記移動体の移動方向に対してほぼ一直線上にあるように配置するのがよい。
【００１３】
これによりボルト１２にて前記移動体に固定されている支持板ボルト穴４４位置の、ロータ回転方向に沿う方向の延長線上に縦刃が位置しているために、該縦刃の押圧強度が最も強くなり、前記袋体が押圧されても支持板が左右方向に湾曲したり前記袋体に斜めに縦刃が食い込んで縦刃の変形が生じる余地がない。
【００１４】
そして前記破袋刃はそれ単独で機能させる事も出来るが、好ましくは、前記破袋空間の前記移動体移動方向の出口側に設けられた容器移動阻止部材と協同作用で初期の目的を達成されるのが良く、この場合は前記移動体上面との間に形成され前記廃棄容器を分離した前記袋体が通過可能な隙間を、前記移動体とともに通過可能に構成されるのがよい。
【００１５】
この場合、前記容器移動阻止部材は、例えば前記移動体の移動方向に対して鋭利な先端を有するＬ字型構造であってもよく、又前記容器移動阻止部材が、前記移動体の移動方向と逆向きに回転駆動されるロータ若しくは周回駆動されるベルト体からなる移動体によって構成されることも可能である。
【００１６】
又、前記隙間と共に若しくは隙間の代わりに、請求項２に記載のような容器噛み込み阻止部材を設けると好ましい。
即ち請求項２記載の発明は、回転駆動されるロータ若しくは周回駆動されるベルト体からなる移動体周面上に取り付けられた破袋刃であって、該移動体上の破袋空間に供給された、ビン、缶、プラスチックボトル等の廃棄容器が入った袋体を破袋して、前記廃棄容器から袋体を分離可能な破袋刃において、
前記破袋刃は、前記移動体に一端が固定され片持ち状態で延在する支持体と、該支持体の自由端側に、前記移動体の移動により前記袋体に切裂せしめる刃先を有し、移動体の移動方向に沿う縦刃と、
前記支持体の固定位置側で固定され、片持ち状態でその自由端側を前記縦刃方向に向け延在させた容器噛み込み阻止部材とを具え、
容器噛み込み阻止部材の自由端側を縦刃起立方向に跳ね上がらせ、該自由端側が板ばね状に揺動可能に構成したことを特徴とする。
【００１７】
さらに前記のような容器噛み込み阻止部材との協同作用によりいかなる種類の廃棄容器に対しても装置を止めることなく連続破除袋可能となるように構成されるのが良い。
【００１８】
又前記破袋刃はベルトコンベアや単一のロータに取り付けても良いが、好ましくは前記移動体が、平行な回転軸心廻りに互いに逆方向に回転せしめられる２個のロータにて構成され、前記破袋空間が該両ロータの間に形成され前記袋体が移動可能な移動空間にて構成され、前記破袋刃が前記ロータ外周に円周方向及び軸方向に沿って複数個取り付けられてなるのがよい。
【００１９】
かかる発明によれば、移動体に取り付けられた破袋刃に、該移動体の移動方向と平行に設けられた縦刃によって、該移動体の移動により袋体を移動体の移動方向に引き裂き、内部の廃棄容器を抜き出すことができるとともに、横刃と容器移動阻止部材との共働によって該袋体を前記移動体の移動方向とほぼ直角方向に引き裂くことにより、該袋体を前記隙間を通過可能となるように小さく切り刻むことができ、さらに加えて、前記支持体の板ばね作用によって破袋刃を袋体に深く食い込ませることにより、いわゆる切れ味が上昇して、従来のものよりも格段に大きな破袋力が得られる。
これにより、移動体の移動方向と平行に設けられた縦刃と該縦刃とほぼ直角方向に延設する横刃とを備えた破袋刃を１対のロータ等の移動体に取り付けるという、きわめて簡単かつコンパクトな構造で以って、内部に廃棄容器が入った袋体を確実に破袋して廃棄容器を分離できるとともに、廃棄容器が分離された袋体を前記容器移動阻止部材と前記移動体上面との間の隙間を通して確実に外部に排出できる。
【００２０】
また、かかる発明によれば、移動体に取り付けられた破袋刃で、該移動体の移動によって袋体を移動体の移動方向に引き裂くことにより廃棄容器分離後の袋体を除袋するように構成されているため、廃棄容器は破袋空間内を滑らかに移動せしめられ、従来技術のように廃棄容器を落下させることがなく、衝突音等による騒音が抑制され、低騒音の運転が実現できる。
【００２１】
更に本第３発明によれば、回転駆動されるロータ若しくは周回駆動されるベルト体からなる移動体周面上に取り付けられた破袋刃であって、該移動体上の破袋空間に供給された、ビン、缶、プラスチックボトル等の廃棄容器が入った袋体を破袋して、前記廃棄容器から袋体を分離可能な破袋刃において、
前記破袋刃は、前記移動体に一端が固定され片持ち状態で延在する支持体と、該支持体の自由端側に、前記移動体の移動により前記袋体に切裂せしめる刃先を有し、移動体の移動方向に沿う縦刃と、
前記破袋空間の前記移動体移動方向の出口側に設けられ、前記廃棄容器を分離した前記袋体が、前記移動体とともに通過可能な隙間を前記移動体上面との間に形成した容器移動阻止部材とを備え、
前記縦刃を、前記移動体の移動方向に沿って複数個列設させて、移動方向前側に位置する第１の刃先高さを後側に位置する縦刃の刃先高さより小にし且つ後側に位置する縦刃の刃先高さを容器移動阻止部材と前記移動体上面隙間より小に形成し、好ましくは前側に位置する第１の刃先と前記移動阻止部材との間に空隙Ｒａを設けたことを特徴とする。
【００２２】
かかる第３発明によれば、図５及び図６に示すように、ビン等の廃棄容器が前記容器移動阻止部材と縦刃の一つとの間に挟まれた場合に単一の縦刃であれば図６に示すように、主刃４１ａと容器移動阻止部材５の先端５ａ間でビン口部１０Ａが挟まれた場合移動体１の移動力により抗してビン口部１０Ａが破開してしまうことになるが、図５のように後方に位置する主刃４１ａ刃先高さＲが容器移動阻止部材５と前記移動体１上面隙間１３より小に構成することにより、前方に位置する補助刃４１ｂ刃先と前記移動阻止部材５との間の空隙Ｒａが、ビン口部１０Ａの半径Ｒｂより小に形成出来、主刃４１ａと移動阻止部材５の先端５ａ間でビン口部１０Ａが挟まれた場合においても主刃４１ａと縦刃４１ｂ刃先先端４６と前記移動阻止部材先端５ａにより狭着されるビン口部１０Ａは半円以下の弧状周面であるために、移動体１の移動力が加わっても前記主刃４１ａと移動阻止部材５の先端５ａに位置するビン口部１０Ａ周面は逃げ角として働いて、ビン口部１０Ａが上方に押し上げられて飛び上がり、ビン等の廃棄容器の狭着による移動体のロックおよびこれにより引き起こされるビン等の割れの発生が回避される。
【００２３】
廃棄容器がビン口を有さない円筒缶の場合は、回転駆動されるロータ若しくは周回駆動されるベルト体からなる移動体周面上に取り付けられた破袋刃であって、該移動体上の破袋空間に供給された、ビン、缶、プラスチックボトル等の廃棄容器が入った袋体を破袋して、前記廃棄容器から袋体を分離可能な破袋刃において、
前記破袋刃は、前記移動体に一端が固定され片持ち状態で延在する支持体と、該支持体の自由端側に、前記移動体の移動により前記袋体に切裂せしめる刃先を有し、移動体の移動方向に沿う縦刃とを備え、
前記縦刃を、前記移動体の移動方向に沿って複数個列設させるとともに、移動方向前方側に位置する第１の刃先高さを後方に位置する縦刃の刃先高さより小にしてなり、
更に前記容器移動阻止部材と隙間を介して対面する支持体の固定位置側で固定され、片持ち状態でその自由端側を移動体の移動方向上流側の前記縦刃方向に向け延在させた容器噛み込み阻止部材を具え、
容器噛み込み阻止部材の自由端側の隙間方向上流側を縦刃起立方向に跳ね上がらせ、該自由端側が板ばね状に揺動可能に構成するのがよい。
【００２４】
即ち廃棄容器がビン口を有さない円筒缶１５の場合でも図７に示すように、円筒缶１５の方向によっては容器移動阻止部材５１と破砕刃４の間に廃棄容器が噛み込んでしまうが、前記に示す容器噛み込み阻止部材９を設けることにより、図８に示すように、容器噛み込み阻止部材９の自由端側９０の板ばね状の跳ね上り部で円筒容器を空中保持させることが出来、これにより容器移動阻止部材５１と破砕刃４の間への廃棄容器１５の噛み込みの発生が回避される。
【００２５】
【発明の実施の形態】
以下、本発明を図に示した実施例を用いて詳細に説明する。但し、この実施例に記載されている構成部品の寸法、材質、形状、その相対配置などは特に特定的な記載がない限り、この発明の範囲をそれのみに限定する趣旨ではなく、単なる説明例にすぎない。
【００２６】
図１は本発明の第１実施例に係る破袋刃の斜視図、図２は第２実施例に係る破袋刃の斜視図、図３は第３実施例に係る破袋刃の斜視図、図４は第４実施例に係る破袋刃の斜視図、図５は第１実施例の作用説明図、図６は第２実施例の作用説明図、図７は第３実施例の作用説明図、図８は第４実施例の作用説明図、図９は破袋動作の説明図、図１０は除袋動作の説明図、図１１は前記破袋刃を備えた破袋・除袋装置の全体斜視図、図１２は前記破袋・除袋装置の正面図である。
【００２７】
本発明にかかる破袋刃を備えた破袋・除袋装置を図１１及び図１２に基づいて説明する。１ａ及び１ｂは円筒状に形成された１対のロータで、回転軸心７ａ及び７ｂが平行になるように配設され、モータ（図示省略）により互いに逆方向に回転せしめられる回転軸２ａ及び２ｂに固着されている。前記１対のロータ１ａ及び１ｂは、その回転軸心７ａ及び７ｂが水平線に対して傾斜角α＝５°〜１０°程度、長手方向において一方向つまり袋体１１を分離した後のビン１０の出口側が下方になるように傾斜せしめられている。
【００２８】
５０は前記傾斜角αを調整するための傾斜角調整装置で、図示しない操作手段により前記回転軸２ａ、２ｂ及びロータ１ａ、１ｂの回転軸心７ａ、７ｂを上下方向に移動せしめて該ロータ１ａ、１ｂの傾斜角αを変化せしめるようになっている。
６は内部にビンが入った袋体１１即ち破袋物を供給するためのコンベア構造のビン供給装置、１４は前記１対のロータ１ａ、１ｂ間の上部に形成された袋体１１の移動空間で、ロータ１ａ及び１ｂの傾斜配置により高位側となっている該移動空間１４の上部側に、前記ビン供給装置６から前記袋体１１が供給されるようになっている。１０は該袋体１１内から出された状態に在るビンを示す。
【００２９】
前記各ロータ１ａ及び１ｂの外周面には、図１１に示されるように、該ロータ１ａ及び１ｂの円周方向に等間隔に、かつ軸方向にも列をなして等間隔に破袋刃４が固定されている（必ずしも円周方向あるいは軸方向に等間隔でなくても千鳥状若しくは段差状に形成してもよい）。また、前記各ロータ１ａ及び１ｂの外周面の、前記破袋刃４取付部の間の部位には、前記ビン１０が入った袋体１１との衝突を緩和するとともに、袋体１１を滑り易くするための外装材７（フッ素ゴムやプラスチック樹脂、摺動性の良好な布、フッ素樹脂テープ等が好適）が貼設されている。
５は前記各ロータ１ａ及び１ｂの外周上部に設けられた容器移動阻止板で、前記移動空間１４に対し、前記各ロータ１ａ及び１ｂの回転方向Ｎにおける出口側部位に、各ロータ１ａ及び１ｂの外周面と所定量の隙間１３を存して設けられている。該隙間１３は、前記ビン１０の口径（通常２５ｍｍ程度）よりもある程度小さく形成され、ビン１０の口部が該隙間内に入り込まず、かつビン１０を分離した前記袋体１１が通過可能となるような寸法に形成されている。
【００３０】
８は未破袋容器排出制御板で、前記移動空間１４の前記ロータ１ａ及び１ｂの傾斜方向下端側（図１２では図上右側）のロータ両周面に近接し、かつ、下側を略三角形状に徐々に狭幅に形成した板状部材で形成され、該板状部材の上部両端を支軸８ａで吊り下げることによりロータ軸方向（図１２の紙面に垂直な方向）に振り子状に揺動可能に構成するとともに、該板状部材の下方に重錘９を設け、前記未破袋容器の押圧により拡開するのを抑制する抑制手段として機能させている。この結果、未破袋容器の押圧により拡開するのを抑制する事が出来るとともに、前記ビン１０から分離した袋体１１のロータ１ａ及び１ｂ側部側への排出を阻止している。尚、該未破袋容器排出制御板８は樹脂や金属板等の剛板の他厚板ゴムで形成してもよく、又下部に取り付けられて制御板８の未破袋袋のビンの押圧による拡開を阻止する重錘は、下方を厚肉に形成しても良く、又重しを封入しても良い。
【００３１】
次に、本発明の第１実施例に係る破袋刃を示す図１において、４は前記ロータ１ａ及び１ｂの外周面に取り付けられた破袋刃であり、前記各ロータ１ａ及び１ｂの回転により前記袋体１１に切裂し破裂せしめる刃先を有する縦刃４１と横刃４２とを、板状の支持板４３上に互いにほぼ直角方向に延設する固定して構成されている。４４は該支持板４３の一端（根元部）に切裂されたボルト穴で、前記支持板４３はその一端側のボルト穴４４に挿通されたボルト１２にて前記ロータ１ａ及び１ｂの外周面に固定されている。
従って、かかる実施例においては、一端（根元部）がボルト１２にて前記ロータ１ａ、１ｂに固定された片持ちの板ばね状支持板４３の自由端部に前記縦刃４１及び横刃４２を固定して構成される。
【００３２】
前記縦刃４１は前記支持板４３の軸方向両側に設けられており、側面が前記ロータ１ａ及び１ｂの円周方向に向き、上方に向けて尖った刃先を有する略三角形状に形成され、固定端である前記ボルト穴４４から遠い側の主刃４１ａと近い側の補助刃４１ｂとを前記各ロータ１ａ、１ｂの回転方向Ｎに沿って列設し、前記ロータ１ａ及び１ｂの回転により刃先が袋体１１に円周方向に食い込み引き裂くように構成している。該主刃４１ａは補助刃４１ｂよりも刃形外形を大きく形成されている。尚、前記縦刃４１は、主刃４１ａ及び補助刃４１ｂを併せて３個以上設けてもよい。
【００３３】
また、前記横刃４２は、前記支持板４３の端部に設けられて、上方に向けて尖った刃先を有する略三角形状に形成された複数の刃が前記ロータ１ａ及び１ｂの軸方向に列設され、破袋刃４が前記容器移動阻止板５の隙間１３に来たとき、該横刃４２と容器移動阻止板５との共働により前記袋体１１を主として軸方向に引き裂き、前記隙間１３を通過可能となるように小さく切り刻むように構成されている。
前記縦刃４１及び横刃４２は支持板４３を折り曲げても、支持板４３とは別体のものを該支持板４３に溶接してもよい。
【００３４】
図２に示される本発明の第２実施例に係る破袋刃４は、前記第１実施例における縦刃４１を１列（第１実施例における主刃４１ａのみ）に構成している。その他の構成は、前記第１実施例と同様であり、これと同一の部材は同一の符号で示す。
【００３５】
図３に示される本発明の第３実施例に係る破袋刃４は、支持板４３のボルト穴４４挿設部側を幅広４３ａに、又その移動方向上流側の主刃４１ａと補助刃４１ｂの形成部をボルト穴４４挿設部間隔と一致させ狭幅４３ｂに形成し、両者間を傾斜部４３ｃを介して一体に形成することにより、前記狭幅４３両側に形成された縦刃４１が、前記移動体（各ロータ１ａ及び１ｂ）の移動(回転)方向に対して支持板４３のボルト穴４４を、とロータ回転方向に沿う方向に一直線状になるように配置したものである。
【００３６】
かかる第３実施例に係る破袋刃４によれば、ボルト１２にて前記ロータ１ａ及び１ｂの外周面に固定されているボルト穴４４位置の、ロータ回転方向に沿う方向の延長線上に主刃４１ａと補助刃４１ｂからなる縦刃が位置しているために、該縦刃の押圧強度が最も強くなり、前記袋体１１が押圧されても支持板が左右方向に湾曲したり前記袋体１１に斜めに縦刃が食い込んで縦刃の変形が生じる余地がない。
尚、その他の構成は、前記第１実施例と同様であり、又同一の部材は同一の符号で示されている。
【００３７】
図４に示される本発明の第４実施例に係る破袋刃４は、前記第３実施例に容器噛み込み阻止部材９を取り付けたものである。その他の構成は、前記第１実施例と同様であり、これと同一の部材は同一の符号で示す。
すなわち本破袋刃４は、ボルト１２にて前記ロータ１ａ及び１ｂの外周面に固定されている支持体を片持ち状態でロータ１ａ及び１ｂ回転方向上流側に延在する自由端側に主刃４１ａと補助刃４１ｂからなる縦刃が位置しているのは図３と同様であって。図３に示す支持板４３のボルト穴４４位置側でボルト１２により共締めにて固定され、片持ち状態でその自由端側を前記縦刃方向に向け延在させた板バネ材からなる容器噛み込み阻止部材を支持部材９上面に重ね合わせる如く固定して、容器噛み込み阻止部材９の自由端側９０を縦刃起立方向に屈曲させて跳ね上がらせ、該自由端側９０が板ばね状に揺動するように構成している。
【００３８】
かかる破袋刃４は後記するように、ビン口を有するビンと共に若しくは単独でアルミ缶やスチール缶若しくはプラスチックや紙容器等の円筒状缶や容器(円筒缶という)が廃棄容器１５として前記袋体１１内に収納されている場合に有効に作用する。
【００３９】
かかる構成からなる破袋刃４を備えた破袋・除袋装置の動作を説明するに、図１１、１２において、内部にビン１０が入った袋体１１は前記ビン供給装置６から前記移動空間１４の上部側に供給され、該移動空間１４において、互いに逆方向に回転せしめられる１対のロータ１ａ及び１ｂの外周に接触しながら、該ロータ１ａ及び１ｂの回転により外側即ち前記容器移動阻止板５の隙間１３側に向かって移動せしめられる。
この際において、前記ロータ１ａ及び１ｂの回転により、該ロータ１ａ及び１ｂの外周面から半径方向に突設された前記破袋刃４の縦刃４１の刃先が、前記ロータ１ａ及び１ｂの回転により袋体１１に円周方向に食い込み、該袋体１１に切裂しこの孔を起点として円周方向に引き裂き、内部のビン１０が移動空間１４内に放出される。
そして、前記ロータ１ａ及び１ｂの回転により該袋体１１が前記容器移動阻止板５の隙間１３に移動せしめられると、前記横刃４２の上方に向けて尖った刃先を有する複数の刃が、前記容器移動阻止板５の下端縁との共働により前記ビン１０を分離した袋体１１を、前記隙間１３を通過可能となるように、小さく切り刻む。
【００４０】
図９及び図１０は前記破袋刃４による袋体１１の破袋動作の状況を示す。同図は破袋刃４として、図２に示す第２実施例に係る縦刃４１が１列のものを用いた場合を示しているが、図１に示す第１実施例に係る破袋刃４を用いた場合でも同一の作用をなす。
図９及び図１０において、ビン１０が入った袋体１１は、前記破袋刃４の縦刃４１に引掛けられ、前記ロータ１ａ及び１ｂの回転によりその回転方向Ｎに移動せしめられながら図９（Ａ）のＡ矢の方向に引張られて、前記縦刃４１の刃先が該袋体１１に円周方向に食い込むことにより切裂され、この孔を起点として円周方向に引き裂かれる。
【００４１】
この際において、前記破袋刃４は、支持板４３の根元部をボルト１２により前記ロータ１ａ及び１ｂの外周面に固定された片持ちの板ばね状に構成されているため、ビン１０の重量によって図９（Ａ）のＢ矢の方向に撓まされた破袋刃４は、支持板部４３のばね力によって図９（Ｂ）のＤ矢のように上方へ反り、このときの上方への弾力によって前記縦刃４１の刃先が前記袋体１１に深く食い込むことにより、該袋体１１が引き裂かれるとともに、内部のビン１０が上方へ飛び出す。
そして、前記のように、該袋体１１が前記容器移動阻止板５の隙間１３にくると、前記横刃４２の複数の刃が、前記容器移動阻止板５の下端縁との共働により前記ビン１０を分離した袋体１１を小さく切り刻み、この袋体１１は前記隙間１３を通過して外部に排出される。

かかる袋体１１の破袋及び除袋動作時において、互いに逆方向に回転せしめられる１対のロータ１ａ及び１ｂの間に形成された移動空間１４内に供給された袋体１１を、該ロータ１ａ及び１ｂの回転により回転方向の外側に移動させつつ、該ロータ１ａ及び１ｂの外周に取り付けられた複数の破袋刃４の縦刃４１によって、ロータ１ａ、１ｂの回転を利用し、かつ前記支持板４３の板ばね作用によって破袋刃４を袋体１１に深く食い込ませ、円周方向に切り裂いて破袋するとともに、該破袋刃４の横刃４２と容器移動阻止板５との共働によって、前記縦刃４１による破袋で前記ビン１０が分離されてロータ１ａ、１ｂと容器移動阻止板５との隙間１３に移動せしめられた該袋体１１を、前記隙間１３を通過可能となるように小さく切り刻むことができる。
さらに前記隙間１３がビン１０の口径よりも小さく形成されているため、該隙間１３にビン１０が挟まれることが回避される。

これに対して、前記のようにビン１０の口径が前記ロータ１ａ、１ｂと容器移動阻止板５との隙間１３よりも大きい場合、前記第１実施例においては、図５に示すように、前記ビン１０は、前記補助刃４１ｂの先端４６により上方に押し上げられて、該ビン１０の中心１０ａが、前記容器移動阻止板５の先端５ａと、ビン１０と前記縦刃４１の主刃４１ａとの接点４５とを結ぶ線４７よりも上側にくることとなり、ロータ１ａ、１ｂの回転とともにビン１０は図のＺ矢印のように飛び上がり、前記第２実施例のようなビン１０が挟まれることが回避される。
【００４６】
即ちより具体的に説明するに、図５のように主刃４１ａ刃先高さＲが容器移動阻止部材５と前記ローラ１上面隙間１３より小であり、且つ補助刃４１ｂ刃先４６と前記移動阻止部材５との間の空隙Ｒａが、ビン口部１０Ａの半径Ｒｂより小に形成することにより、主刃４１ａと移動阻止部材５の先端５ａ間でビン口部１０Ａが挟まれた場合においても主刃４１ａと補助刃４１ｂ刃先先端４６と前記移動阻止部材先端５ａにより狭着されるビン口部１０Ａは半円以下の弧状周面であるために、ローラ１の移動力が加わっても前記主刃４１ａと移動阻止部材５の先端５ａに位置するビン口部１０Ａ周面は逃げ角として働いて、ビン口部１０Ａが上方に押し上げられて飛び上がり、ビン１０の狭着による板遺体のロックやおよびこれにより引き起こされるビン等の割れの発生が回避される。
【００４７】
また、図７及び図８はビン口を有するビンと共に若しくは単独でアルミ缶やスチール缶若しくはプラスチックや紙容器等の円筒状缶や容器(円筒缶という)が廃棄容器１５として前記袋体１１内に収納されている場合の問題点と解決方法を示し、廃棄容器としての円筒缶１５が前記ロータ１ａ、１ｂ上の移動空間１４の円筒状の容器移動阻止部材５１の近傍にきた場合の状況を示しており、図７は図３に示す第３実施例の破袋刃４を用いた場合、図８は図４に示す第４実施例の破袋刃４を用いた場合の夫々の実施例である。

【発明の効果】
以上記載の如く本発明によれば、移動体の移動方向に略平行に設けられた縦刃と該縦刃とほぼ直角方向に延設する方向に設けられた横刃とを備えた破袋刃を１対のロータ等の移動体に取り付けるという、きわめて簡単かつコンパクトな構造で以って、破袋刃のいわゆる切れ味が上昇して、従来のものよりも格段に大きな破袋力が得られる。
これにより、内部に廃棄容器が入った袋体を確実に破袋して廃棄容器を分離できるとともに、廃棄容器が分離された袋体を前記容器移動阻止部材と前記移動体上面との間の隙間を通して確実に外部に排出できる。
【００５１】
また、本発明によれば、移動体に取り付けられた破袋刃で、該移動体の移動によって袋体を移動体の移動方向に引き裂くことにより廃棄容器分離後の袋体を除袋するように構成されているため、廃棄容器は破袋空間内を滑らかに移動せしめられ、従来技術のように廃棄容器を落下させることがなく、衝突音等による騒音が抑制され、低騒音の運転が実現できる。
【００５２】
特に破袋刃の縦刃は、支持体を移動体に固定する固定部分に対し、前記移動体の移動方向に対してほぼ一直線上にあるように配置することにより、前記袋体が押圧されても支持板が左右方向に湾曲したり前記袋体に斜めに縦刃が食い込んで縦刃の変形が生じる余地がなく、円滑な引き裂きが可能となる。
【００５３】
さらに請求項１１のように構成すれば、ビン等の廃棄容器が前記容器移動阻止部材と縦刃の一つとの間に挟まれた場合においても、他の縦刃の先端により廃棄容器が上方に押し上げられて飛び上がり、ビン等の廃棄容器が挟まれることおよびこれにより引き起こされるビン等の割れの発生が回避される。
特にビン口を有さない円筒缶が廃棄容器１５の場合は、請求項２や１２に示すように構成することにより容器噛み込み阻止部材の自由端側の板ばね状の跳ね上り部で円筒容器を空中保持させることが出来、これにより容器移動阻止部材と破砕刃の間への廃棄容器の噛み込みの発生が円滑に回避される。
【００５４】
要するに、本発明によれば、ヒータ等の格別な袋体の溶融手段が不要となり、簡単な構造で以って袋体の破袋力を増大することができて、廃棄容器と袋体との分離を効率的かつ確実に行うことができるとともに、破袋及び除袋騒音が低減された破袋装置を提供することができる。

In the waste disposal facility, the waste container and the bag body are separated from the waste containing a waste container such as a bottle, a can, and a plastic bottle in a bag body having a relatively large bag breaking strength such as a plastic bag, and the waste container A bag-breaking device that recycles the bag body and removes the bag body to the outside is installed as one of the processing facilities.
[0003]
As technologies relating to such bag breaking devices, there are provided inventions such as JP-A 2000-79349, JP-A 10-5614, JP-A 8-119405, and JP-A 10-230184.
In Japanese Patent Application Laid-Open No. 2000-79349, an endless conveyor having a plurality of claws arranged along a moving part is disposed so that the moving direction of the upper moving part is positioned at a high position, and the claw passes therethrough. A plate having possible slits is disposed above the endless conveyor along the upper moving part of the endless conveyor, while one end is in contact with or close to the plate and the free end side is located outside the plate. The dam plate is provided with a slit through which the claw can pass, and the claw has an elastic member and swings in the direction opposite to the moving direction according to the resistance applied to the claw tip portion. It is configured to be possible or upset.
[0004]
In the invention disclosed in Japanese Patent Laid-Open No. 10-5614, a dust input port is provided at the upper part of the casing, a rotor is provided at the lower part, a discharge port such as a bottle is provided below, an air outlet, and a broken bag of garbage bags.

[0005]
[Problems to be solved by the invention]
However, the prior art has the following problems.
That is, in Japanese Patent Application Laid-Open No. 2000-79349, an endless conveyor in which a plurality of claws are arranged along a moving part is provided, so that the length of the device is increased, the size of the device is increased, and the cost of the device is high. Become.
Also, when a bag containing a bottle is hung on a claw and goes up the slope of an endless conveyor, the bag will come off the claw and fall below the endless conveyor, causing the internal bin to crack and make recovery impossible See the occurrence of.
[0006]
Further, in such a conventional technique, a bag containing a bottle is carried along a long endless conveyor to the upper end of the conveyor, and the bag is broken by a dam plate provided corresponding to the upper end. Since the bottle is dropped, the noise is loud due to the collision sound between the bins, the collision sound when the bottle falls while colliding with the surface of the conveyor or the claw, and the like.
[0007]
Furthermore, in this prior art, a plurality of claws attached to the conveyor via the slats and mounting seats in the moving direction of the conveyor are sent by the conveyor and cut into bags at the tips of the claws. It is configured to tear the bag body at the tip of the nail by movement of the so-called sharpness is not sufficient and it is difficult to obtain a large bag breaking force, so that the bottle cannot be reliably pulled out from the bag body, A situation where the bag body and the bottle are not separated occurs, and a sufficient bag breaking effect cannot be obtained.
And so on.
[0008]
In the invention of Japanese Patent Laid-Open No. 10-5614, a bag containing a bottle is melted by a reverse V-shaped blade attached to the outer periphery of the rotor along the circumferential direction and a heater according to the rotation of one rotor. Since the bag that has broken and adhered to the blade is scraped off by the groove edge of the baffle plate, the period during which the bag is torn and torn by the blade is short, and the bag is melted by the heater. Even if the action is added, the bag and the bottle are not sufficiently separated from each other, the bag remains attached to the bottle side, and the bottle is not sufficiently collected.
[0009]
In JP-A-8-119405, a garbage bag is melted and teared by a sheathed heater, and if the garbage bag is welded to the sheathed heater or is flammable, there is a risk of accidental combustion.
[0010]
Japanese Patent Application Laid-Open No. 10-230184 also prevents the garbage bag from breaking by blocking the progress of the garbage bag conveyed by the conveyor with a catcher having a blade plate at the tip. Becomes complicated.
[0011]
In view of the problems of the prior art, the present invention increases the bag breaking force of the bag body with a simple structure that does not require a special bag melting means such as a heater, and separates the waste container from the bag body. It is an object of the present invention to provide a bag breaking blade structure that can efficiently and reliably perform the bag breaking and bag removal noise.
[0012]
[Means for Solving the Problems]
In order to solve such a problem, the present invention provides a bag breaking blade attached on a circumferential surface of a movable body comprising a rotor that is rotationally driven or a belt body that is rotationally driven.

The vertical blade is preferably arranged so as to be substantially in a straight line with respect to the moving direction of the moving body with respect to the fixed portion for fixing the support to the moving body.
[0013]
As a result, since the vertical blade is located on the extended line in the direction along the rotor rotation direction of the position of the support plate bolt hole 44 fixed to the moving body by the bolt 12, the pressing strength of the vertical blade is the highest. Even if the bag body is pressed, there is no room for the support plate to bend in the left-right direction or for the vertical blade to bite into the bag body and to deform the vertical blade.
[0014]
The bag breaking blade can function alone, but preferably, the initial purpose is achieved in cooperation with a container movement blocking member provided on the outlet side of the moving body moving direction of the bag breaking space. In this case, it is preferable that a gap formed between the upper surface of the movable body and the bag body separated from the waste container can be passed with the movable body.
[0015]
In this case, the container movement blocking member may be an L-shaped structure having a sharp tip with respect to the moving direction of the moving body, for example. It is also possible to be constituted by a moving body composed of a rotor driven to rotate in the opposite direction or a belt body driven to rotate.

[0017]
Furthermore, it is preferable that the bag can be continuously broken without stopping the apparatus for any kind of waste container by the cooperative action with the container biting prevention member as described above.
[0018]
orSaidThe bag breaking blade may be attached to a belt conveyor or a single rotor, but preferably the moving body is composed of two rotors that are rotated in opposite directions around a parallel rotation axis, and A bag space is formed between the rotors, and the bag body is configured as a movable space in which the bag body can move. A plurality of the bag breaking blades are attached to the outer periphery of the rotor along the circumferential direction and the axial direction. Is good.

According to this invention, the moving direction of the movable body is attached to the bag breaking blade attached to the movable body.And flatThe vertical blade provided in the row can tear the bag body in the moving direction of the moving body by the movement of the moving body and take out the internal waste container, and the cooperation of the horizontal blade and the container movement preventing member The bag body is in a direction substantially perpendicular to the moving direction of the moving body.To pullBy tearing, the bag body can be chopped into small pieces so as to be able to pass through the gap, and in addition, by making the bag breaking blade deeply bite into the bag body by the leaf spring action of the support body, so-called The sharpness is increased, and a bag breaking force much greater than that of the conventional one can be obtained.
As a result, the moving direction of the moving bodyParallel toA vertical blade provided on the base and extending in a direction substantially perpendicular to the vertical bladeNext toA bag breaking blade equipped with a blade is attached to a moving body such as a pair of rotors, etc. With a very simple and compact structure, the bag body containing the waste container is securely broken and discarded. Can be separated, and the bag body from which the waste container is separated can be reliably discharged to the outside through the gap between the container movement prevention member and the upper surface of the movable body.
[0020]
According to the invention, the bag breaker blade attached to the movable body is used to tear the bag body in the moving direction of the movable body by the movement of the movable body, thereby removing the bag body after separation of the waste container. Because it is configured, the waste container can be moved smoothly in the bag breaking space, and the waste container is not dropped as in the prior art, noise due to collision noise, etc. is suppressed, and low noise operation can be realized. .
