Description

【０００１】
【発明の属する技術分野】
本発明は自動車のフロントガラス等に用いる合せガラスの分離回収方法に関する。
【０００２】
【従来の技術】
自動車のフロントガラスや建築物の窓ガラスとして合せガラスが用いられている。この合せガラスは外側ガラス（例えば強化ガラス）と内側ガラス（例えば紫外線吸収ガラス）とを中間膜（例えばポリビニルブチラール）にて接合一体化したものである。
【０００３】
廃車などの際の資源の有効利用を考えた場合、ガラス（外側ガラスと内側ガラス）と樹脂（中間膜）とを分離回収する必要がある。しかしながら、ガラスを細かく破砕しても中間膜は破砕することはできず、中間膜に細かなガラス片が強固に接合されたままとなり簡単には分離できない。
【０００４】
そこで、ポリビニルブチラールの性質、即ち、水に接触すると水を吸って膨潤し接合力が極めて弱くなる性質を利用して分離する技術が特開昭５１−４６３０８号公報或いは特開平７−１７７４６号公報に開示される技術が提案されている。
【０００５】
特開昭５１−４６３０８号公報には、合せガラスに割目を入れた後、水に浸漬するなどして中間膜を膨潤せしめた後、外力を加えて中間膜とガラス片とを分離することが開示され、特開平７−１７７４６号公報には、中間膜を膨潤せしめた後、合せガラスの片側に吸引装置を配置し、強制的に中間膜表面に付着しているガラス片を剥離することが開示されている。
【０００６】
【発明が解決しようとする課題】
合せガラスを製造する際には、間に空気が入らないように減圧した状態で中間膜とガラスとを合わせる。したがって、合せガラスを破砕して細かなガラス片とした状態でも図３に示すようにガラス片と中間膜との間は吸着状態となっているため、特開昭５１−４６３０８号公報のように単純に中間膜を膨潤させただけでは中間膜に付着したまま残ってしまうガラス片がある。
【０００７】
一方、特開平７−１７７４６号公報のように強制的にガラス片を吸引除去する方法にあっては、吸引口よりもガラス片が大きかったり、吸引口にガラス片がかかったりすると、吸引力によってガラス片が中間膜に入り込み接合力が却って強固になってしまうことがある。
【０００８】
【課題を解決するための手段】
上記課題を解決するため本発明に係る合せガラスの分離回収方法は、中間膜を介して接合されている合せガラスを破砕し、次いで前記中間膜を含水せしめて膨潤させ、この後ガラスの破片が付着している膨潤した前記中間膜を減圧室に送り込み、この減圧室を出た後若しくは減圧室内で中間膜とガラスの破片とを分離し回収する構成とした。
【０００９】
中間膜からガラスの破片を効果的に分離するには、中間膜の一部を掃除機のような減圧手段にて吸引するのではなく、中間膜全体を一定の減圧雰囲気内にセットすることが必要となる。
【００１０】
また、極端な減圧雰囲気下に置くと却って中間膜とガラスの破片との密着力が増すため、減圧室内の圧力は−２〜−３ｋｇ／ｃｍ２（１気圧よりも２〜３ｋｇ／ｃｍ２だけ負圧）とするのが好ましい。
【００１１】
また、本発明に係る合せガラスの分離回収システムは、中間膜を介して接合されている合せガラスを破砕する破砕装置と、破砕されたガラス片が付着している中間膜を膨潤させる水槽若しくは蒸気室と、膨潤した中間膜を減圧雰囲気で所定時間保持する減圧室と、この減圧室の下流側または減圧室内に配置され、減圧処理された中間膜からガラス片を分離する分離装置とを備えている。
【００１２】
【発明の実施の形態】
以下に本発明の実施の形態を添付図面に基づいて説明する。図１は本発明に係る合せガラスの分離回収方法を適用したシステムの全体図であり、分離回収システム１は合せガラスＧを破砕する破砕装置１０の下流側に水槽２０を連続して配置し、この水槽２０の下流側に減圧室３０を連続して配置し、この減圧室３０の下流側に分離回収装置４０を配置している。尚、破砕装置１０の近傍にはストッカー２を配置している。
【００１３】
破砕装置１０は送りローラ１１の終端に一対の破砕ローラ１２,１２を配置している。この破砕ローラ１２は表面にスパイク状の突起１３を千鳥状に多数植設してなり、破砕ローラ１２,１２間に送り込まれた合せガラスＧを細かく破砕する。尚、中間膜Ｐは破砕されないので、中間膜Ｐの表面に破砕された多数のガラス片が付着した状態になる。
【００１４】
また、中間膜Ｐの下面に付着しているガラス片の一部は重力によって分離するため、このガラス片をダクト状のガイド１４を介して破砕装置の底部に配置したボックス１５に回収するようにしている。
【００１５】
破砕装置１０に隣接する水槽２０内には多数のパレット２１が配置され、これらパレット２１はチェーン２２を駆動することで水槽２０内を循環する。水槽２０内には常温水若しくは温水を供給している。常温水（０〜２０℃）の場合には水槽内に２４時間合せガラスＷを浸漬しておく必要があるが、温水（８０℃）の場合には約１時間で十分に中間膜が膨潤する。したがって、水の温度に応じてパレット２１の移動速度を調整する。
なお、図示例では水槽を挙げたが、蒸気室或いはミスト室を用いることも可能である。
【００１６】
前記水槽２０に隣接する減圧室３０内の上部には送りローラ３１を設け、底部には搬送中に中間膜Ｐの下面から落下するガラス片を回収するボックス３２を配置し、さらに減圧室３０は図示しない真空ポンプなどにつながり、内部の圧力を１気圧よりも２〜３ｋｇ／ｃｍ2だけ負圧に設定している。
【００１７】
また、減圧室３０の下流側に隣接して配置される分離回収装置４０は、第１の搬送路４１と第２の搬送路４２を備え、第１の搬送路４１は基台４３上にスプリング４４を介して下流側が若干下方に傾斜するように支持されるとともに、図示しない加振装置に連結し、更に搬送面を金網などのメッシュ材４５にて構成している。
【００１８】
一方、第２の搬送路４２は第１の搬送路４１の下流端の下方に配置され、基台４６上に上流側が下方に傾斜するように支持されるとともに、図示しない加振装置に連結し、更に搬送面を金網などのメッシュ材４７にて構成している。
【００１９】
而して、減圧室３０から第１の搬送路４１のメッシュ材４５上に送り出された合せガラスＷは振動により徐々に下流側に移動するとともに、中間膜Ｐの下面に残っているガラス片は下方に振い落され、ガイド４８を介してボックス４９内に回収される。また、第１の搬送路４１から第２の搬送路４２に移る際に合せガラスＷは反転し、反転して下面となった面に付着していたガラス片がメッシュ材４７を通してボックス５０内に回収される。また、ガラス片が剥離した中間膜Ｐはボックス５１に回収される。
【００２０】
図２は別実施例を示す図１と同様の図であり、この実施例にあっては減圧室３０内に分離回収装置４０を配置することで、分離回収システム全体をコンパクトなものにしている。
【００２１】
【発明の効果】
以上に説明したように本発明によれば、合せガラスを破砕して中間膜とガラスとを分離回収するにあたり、破砕後に減圧室にガラス片が付着した中間膜を送り込むようにしたので、ガラス片と中間膜とが気密に密着している状態を解除でき、容易に中間膜からガラス片を剥離することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for separating and collecting laminated glass used for a windshield of an automobile.
[0002]
[Prior art]
Laminated glass is used as a windshield for automobiles and window glass for buildings. This laminated glass is obtained by joining and integrating an outer glass (for example, tempered glass) and an inner glass (for example, ultraviolet absorbing glass) with an intermediate film (for example, polyvinyl butyral).
[0003]
When considering the effective use of resources at the time of scrap cars, it is necessary to separate and recover glass (outer glass and inner glass) and resin (intermediate film). However, even if the glass is crushed finely, the intermediate film cannot be crushed, and fine glass pieces remain firmly joined to the intermediate film and cannot be easily separated.
[0004]
Therefore, a technique for separating using the property of polyvinyl butyral, that is, the property of absorbing and swelling when it comes into contact with water and the bonding force becomes extremely weak is disclosed in Japanese Patent Laid-Open No. 51-46308 or Japanese Patent Laid-Open No. 7-17746. Has been proposed.
[0005]
Japanese Patent Application Laid-Open No. 51-46308 discloses that an interlayer film is swelled by immersing it in water after being split in a laminated glass, and then applying an external force to separate the interlayer film from the glass piece. JP-A-7-17746 discloses that after the interlayer film is swollen, a suction device is arranged on one side of the laminated glass to forcibly peel off the glass piece adhering to the interlayer film surface. Is disclosed.
[0006]
[Problems to be solved by the invention]
When producing a laminated glass, the interlayer film and the glass are combined in a state where the pressure is reduced so that air does not enter between them. Therefore, even when the laminated glass is crushed into fine glass pieces, as shown in FIG. 3, since the glass pieces and the intermediate film are in an adsorbed state, as disclosed in JP-A-51-46308. There is a glass piece that remains attached to the intermediate film simply by swelling the intermediate film.
[0007]
On the other hand, in the method of forcibly removing a glass piece as disclosed in JP-A-7-17746, if the glass piece is larger than the suction port or the glass piece is applied to the suction port, The glass piece may enter the intermediate film and the bonding force may be strengthened instead.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the method for separating and recovering laminated glass according to the present invention crushes laminated glass joined via an intermediate film, then hydrates and swells the intermediate film, and glass fragments thereafter. The adhering swollen interlayer film is fed into a decompression chamber, and after leaving the decompression chamber or in the decompression chamber, the interlayer film and glass fragments are separated and recovered.
[0009]
In order to effectively separate glass fragments from the interlayer film, the entire interlayer film should be set in a constant reduced-pressure atmosphere, rather than sucking a part of the interlayer film with a vacuum means such as a vacuum cleaner. Necessary.
[0010]
Moreover, due to the increased rather when placed under extreme pressure atmosphere adhesion between pieces of the intermediate film and the glass, the pressure in the vacuum chamber -2~ - 3kg / cm 2 (only 2 ~3kg / cm 2 than 1 atmosphere Negative pressure) is preferable.
[0011]
In addition, the laminated glass separation and recovery system according to the present invention includes a crushing device that crushes laminated glass joined via an intermediate film, and a water tank or steam that swells the intermediate film to which the crushed glass pieces are attached. A decompression chamber that holds the swollen interlayer film in a decompressed atmosphere for a predetermined time; and a separation device that is disposed downstream of the decompression chamber or in the decompression chamber and separates the glass pieces from the decompressed interlayer film. Yes.
[0012]
