【発明の属する技術分野】
本発明は、石膏ボードから表装紙と石膏とを分離する装置に関するものである。
【0002】
【従来の技術】
解体される家屋等からは多量の石膏ボードが排出されている。そして、近年産業廃棄物の処理場の選定難等の理由から石膏を再加熱してリサイクルすることが検討されている。しかし、石膏ボードは石膏の表裏に表装紙が貼着されており、加熱に先立ってこの表装紙を分離する必要がある。
【0003】
そこで、本出願人は図8に示す石膏ボードの表装紙分離装置10aを開発した(特許文献1参照。)。この装置10aは、回転する回転圧縮体11,11の間に石膏ボード1を挿入通過させて、石膏ボード1を圧縮又は変形させ、表装紙2と石膏3との間にずれを発生させることにより、表装紙2,2間に貼着されている石膏3を粉々にして容易に分離することができるようにしたものである。

特開2002−28509号公報
【0005】
【発明が解決しようとする課題】
しかしながら、上記従来の構成では、表装紙2と石膏3との間の付着力が強い場合には表装紙2に石膏3が残り表装紙2と石膏3とを完全に分離するまでには至らなかった。また、石膏3は回転圧縮体11,11間で圧縮されることによって、却って表装紙2側に弱い力で付着して残るものもあった。
【0006】
本発明は上記点に鑑み、石膏ボードが圧縮体通過後に表装紙に付着する石膏を略完全に除去することができる石膏ボード表装紙分離装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
請求項1の発明は、石膏ボードから表装紙と石膏とを分離する装置であって、対向配置された一対の回転圧縮体の間に前記石膏ボードを通過させて該石膏ボードを圧縮又は変形させた後、回転軸の長手方向に沿って複数のブレードが取り付けられた回転体と前記回転圧縮体の一方との間を通過させることに特徴を有する。
【0008】
請求項2の発明は、回転圧縮体近傍には分離された表装紙が回転圧縮体に巻き込まれることを防止する巻き込み防止部材が設置されていることに特徴を有する。
【0009】
請求項3の発明は、対向配置された一対の回転圧縮体の間隔を調整することができる圧縮幅調整機構を備えていることに特徴を有する。
【0010】
請求項4の発明は、回転圧縮体と複数のブレードが取り付けられた回転体との間隔を調整することができる幅調整機構を備えていることに特徴を有する。
【0011】
【発明の実施の形態】
次に、本発明の実施形態を図面に基づいて説明する。図1は本発明に係る石膏ボード表装紙分離装置の全体を示す一部断面斜視図であり、図2は正面図である。
【0012】
まず、本発明に係る石膏ボード表装紙分離装置10には、一対の回転圧縮体11,11が石膏ボード1の挿入される間隔を空けて対向配置されている。そして、回転圧縮体11,11の下方には複数のブレード4a,4a,・・が設置された回転体4,4が対向配置されているのである。また、一対の回転圧縮体11,11の外側には各々巻き込み防止部材5,5が設置されている。
【0013】
さらに、複数のブレード4aが設置された回転体4の下方には石膏受皿6を傾斜させて設置している。そして、この傾斜している石膏受皿6上に落下した石膏3は石膏回収箱7によって回収されるのである。
【0014】
また、回転圧縮体11及び回転体4の両側には回転圧縮体11,11間の間隔を調整することができる圧縮幅調整機構8と回転圧縮体11と複数のブレード4aが設置された回転体4との間隔を調整することができる幅調整機構9とが設置されている。
【0015】
図3〜図5は石膏ボード表装紙分離装置によって表装紙から石膏が取り除かれる手順を示す説明図である。
【0016】
先ず、図3に示すように一対の回転圧縮体11,11の間に石膏ボード1を上方から挿入するのである。すると、回転圧縮体11,11の回転によって石膏ボード1は圧縮及び変形されながら両側の表装紙2,2が回転圧縮体11,11に巻き付くように回転方向に進行していくのである。一方、石膏3は回転圧縮体11,11による石膏ボード1の圧縮及び変形によるずれの発生によって粉砕され、重力によって下方に設置されている図1及び図2で示した石膏受皿6へと落下するのである。
【0017】
次に、図4に示すように各々の表装紙2,2が回転圧縮体11,11の回転方向に運ばれていくと複数のブレード4a,4a,・・が設置された回転体4,4が回転することによって各々の表装紙2,2に残っている石膏3をブレード4a,4a,・・が掻き取って行くのである。そして、ブレード4a,4a,・・によって掻き取られた石膏3は回転体4,4が回転することによって、下方に設置されている石膏受皿6へと落下するのである。
【0018】
そして、図5に示すように石膏3が略完全に掻き取られた表装紙2,2は回転圧縮体11,11の回転方向に沿って進行して行くのであるが、この表装紙2,2が回転圧縮体11,11間に再度巻き込まれて装置10に不具合が生じることがないように、一対の回転圧縮体11,11の外側には各々巻き込み防止部材5,5が設置されて各々の表装紙2,2を下方に排出するようにしているのである。
【0019】
また、本発明に係る石膏ボード表装紙分離装置10は石膏ボード1の幅が変化する場合に対応できるように圧縮幅調整機構8と幅調整機構9とが設置されていて、図1及び図6に示すように圧縮幅調整機構8は一対の回転圧縮体11,11の間隔Aを調整することができるようにして回転圧縮体11,11間に挿入される石膏ボード1の厚さが異なる場合にも対応することができ、圧縮力を調整することもできるようにしている。
【0020】
同様にして幅調整機構9は各々の回転圧縮体11,11と、その下方に位置する回転体4,4との間隔Bを調整することができるようにして、この間を通過する表装紙2,2の厚さが異なる場合にも対応することができるようにしている。
【0021】
図7は本発明の石膏ボード表装紙分離装置を構成する回転体を示す説明図である。この図に示すように回転体4は回転軸4bの長手方向に沿って複数の硬質のブレード4a,4a,・・が取り付けられているものであって、このブレード4a,4a,・・が回転することによって表装紙2,2に付着している石膏3を掻き取り、各ブレード4a,4a間の溝に一旦、石膏3を落し込むのである。そして、上述したとおり重力によって下方に設置されている石膏受皿6へと落下し、石膏回収箱7によって回収されるのである。
【0022】
尚、本発明の趣旨を逸脱しない範囲において、種々の実施形態をとることができることは言うまでもない。例えば、上記実施形態においては回転圧縮体11,11を2個設置する構成としているがこれに限定されるものではなく、3個又は4個或いはさらに複数個設置する構成としてもよいものである。また、上記実施形態においては2個の回転圧縮体11,11を対向配置しているが石膏ボードの進行方向に沿って互い違いに配置する構成としてもよいものである。さらに、設置される複数の回転圧縮体11,11・・の径は同径としなくてもよいものである。また、回転圧縮体11及び回転体4を回転させる駆動源は図示せず省略したが、モータであっても手動によるものであってもよいものである。
【0023】
【発明の効果】
請求項1の発明は、石膏ボードから表装紙と石膏とを分離する装置であって、対向配置された一対の回転圧縮体の間に前記石膏ボードを通過させて該石膏ボードを圧縮又は変形させた後、回転軸の長手方向に沿って複数のブレードが取り付けられた回転体と前記回転圧縮体の一方との間を通過させることに特徴を有するので、先ず、石膏ボードが回転圧縮体間を通過することによって石膏ボードを圧縮又は変形させ、表装紙と石膏との間にずれを発生させて表装紙と石膏とを大まかに分離させることができる。さらに、表装紙に付着したままの石膏は回転体のブレードによって掻き取られるので、表装紙と石膏とを略完全に分離させることができる。
【0024】
請求項2の発明は、回転圧縮体近傍には分離された表装紙が回転圧縮体に巻き込まれることを防止する巻き込み防止部材が設置されていることに特徴を有するので、回転圧縮体と回転体との間を通過した表装紙が回転圧縮体間に再度巻き込まれて装置に不具合が生じることを防ぐことができる。

3 to 5 are explanatory diagrams showing a procedure for removing gypsum from the cover paper by the gypsum board cover paper separating apparatus.
[0016]
First, as shown in FIG. 3, the gypsum board 1 is inserted between the pair of rotary compression bodies 11, 11 from above. Then, while the gypsum board 1 is compressed and deformed by the rotation of the rotary compression bodies 11, 11, the gypsum board 1, 2 advances in the rotation direction so as to wind around the rotary compression bodies 11, 2. On the other hand, the gypsum 3 is pulverized by the displacement of the gypsum board 1 due to the compression and deformation of the gypsum board 1 by the rotary compression bodies 11 and 11 and falls by gravity onto the gypsum tray 6 shown in FIGS. It is.
[0017]
Next, as shown in FIG. 4, when each of the facing sheets 2, 2 is conveyed in the rotation direction of the rotary compression bodies 11, 11, the rotary bodies 4, 4 on which a plurality of blades 4a, 4a,. The blades 4a, 4a,... Scrape off the plaster 3 remaining on each of the facing sheets 2, 2 by the rotation of. Then, the gypsum 3 scraped off by the blades 4a, 4a,... Falls onto the gypsum pan 6 installed below by the rotation of the rotating bodies 4, 4.
[0018]
As shown in FIG. 5, the cover paper 2, 2 from which the gypsum 3 has been almost completely scraped advances along the rotation direction of the rotary compression bodies 11, 11.
