Description

本発明は、合わせガラスのガラスと中間膜とを分離する装置、特に、破砕された合わせガラスからガラス片と中間膜とを分離する装置に関する。   The present invention relates to an apparatus for separating a laminated glass from an intermediate film, and more particularly to an apparatus for separating a glass piece and an intermediate film from crushed laminated glass.

建設資材用ガラス、自動車用窓ガラスなどには、2枚のガラスの間に樹脂の中間膜（例えばPVB）を入れ、強度を向上させた「合わせガラス」が多く使用されている。しかし、建設用ガラスの破材、中古自動車の廃棄（年間300万台）により、合わせガラスの廃棄物が大量に発生している。
従来より、合わせガラスのリサイクル方法として、例えば、合わせガラスを破砕し、その後中間膜に引っ張り歪みを与えることでガラスと中間膜とを分離する方法（特許文献1）や、中間膜を介して接合されているガラス板を破砕し、破砕されたガラス板のガラス片が付着している中間膜を膨潤させ、上流側の搬送ローラ対による合わせガラスの送り速度よりも下流側の搬送ローラ対による合わせガラスの送り速度が速くなるように設定して合わせガラスを引き伸ばし、引き伸ばされた中間膜からガラス片を分離して回収する方法（特許文献2）等が提案されている。
特開２００４−１８１３２１号公報 特開２００２−３２６８４９号公報 For glass for construction materials, window glass for automobiles, etc., “Laminated glass” is often used in which a resin interlayer (for example, PVB) is inserted between two glasses to improve the strength. However, a lot of laminated glass waste is generated due to broken glass for construction and used car disposal (3 million units per year).
Conventionally, as a method of recycling laminated glass, for example, a method of crushing laminated glass and then separating the glass and the intermediate film by applying tensile strain to the intermediate film (Patent Document 1) or joining via an intermediate film Crushing the glass plate that has been shattered, swell the intermediate film to which the glass pieces of the crushed glass plate are adhered, and aligning with the conveying roller pair on the downstream side than the feeding speed of the laminated glass on the upstream conveying roller pair There has been proposed a method (Patent Document 2) or the like in which a laminated glass is stretched by setting the glass feed rate to be high, and a glass piece is separated and recovered from the stretched intermediate film.

しかしながら、合わせガラスを中間膜剥離液に浸潰せずに、合わせガラスのガラスを破砕して、合わせガラスを引っ張ることによって中間膜から破砕ガラスを分離する方法では、大きな塊の破砕ガラス片を中間膜から容易に分離することができるものの、細かい屑状（例えば、直径5mm以下）の破砕ガラス片を中間膜から容易に除去することができなかった。
また、高温水（例えば、80℃以上の水）にガラスを破砕した合わせガラスを浸潰して、中間膜と破砕ガラスとを分離する方法では、中間膜における含水量が多くなり、中間膜をリサイクル可能な状態で分離することができなかった。
本発明の目的は、短時間でガラスと中間膜とを分離することができる分離装置を提供することにある。 However, in the method of breaking the laminated glass from the intermediate film by crushing the laminated glass without pulling the laminated glass in the intermediate film peeling solution, and pulling the laminated glass, However, it was not possible to easily remove fine glass fragments (for example, having a diameter of 5 mm or less) from the intermediate film.
In addition, the method of separating the intermediate film from the crushed glass by pulverizing the laminated glass that has been crushed into high-temperature water (for example, water of 80 ° C. or higher) increases the water content in the intermediate film and recycles the intermediate film. It was not possible to separate it.
An object of the present invention is to provide a separation apparatus capable of separating glass and an intermediate film in a short time.

本発明は、破砕された合わせガラスからガラス片と中間膜とを分離する装置において、
剥離剤を含む水溶液中に下部が浸漬され、穴あき板で構成され、内部表面に複数個の突起が設けられた金属製の回転円筒状ドラムを少なくとも有し、前記回転円筒状ドラムの内部に投入された前記破砕合わせガラスを前記円筒状ドラムの回転により、前記水溶液に浸漬させながら揉みほぐすことにより、前記中間膜から大部分のガラス片を剥離させる剥離機と、
円筒容器内に設けられた羽根車と、この羽根車の下部に設けられた金属製の半円筒状の穴あき板とを少なくとも有し、前記剥離機から取り出された、残りのガラス片が付着している中間膜を、前記羽根車で前記半円筒上の穴あき板に回転させながら押しつけて、残りのガラス片を中間膜から剥離してガラス片と中間膜と分別する分別機とを備えることを特徴とする。 The present invention is an apparatus for separating a glass piece and an intermediate film from crushed laminated glass,
At least a metal rotating cylindrical drum having a lower part immersed in an aqueous solution containing a release agent, composed of a perforated plate, and provided with a plurality of protrusions on the inner surface, is provided inside the rotating cylindrical drum. A peeling machine that peels most glass pieces from the intermediate film by squeezing and loosening the crushed laminated glass that has been put into the aqueous solution by rotating the cylindrical drum;
It has at least an impeller provided in a cylindrical container and a metal semi-cylindrical perforated plate provided in the lower part of the impeller, and the remaining glass pieces taken out from the peeling machine are attached. A separating machine that presses the intermediate film that is being rotated against the perforated plate on the semi-cylinder with the impeller and separates the remaining glass pieces from the intermediate film to separate the glass pieces from the intermediate film. It is characterized by that.

本発明によれば、合わせガラスを短時間でガラス片と中間膜に分離することが可能となる。分離されたガラス片は、カレットとしてガラス製品の製造に再利用され、中間膜は樹脂材料としての再利用が可能となる。   According to the present invention, it is possible to separate a laminated glass into a glass piece and an intermediate film in a short time. The separated glass piece is reused as a cullet for the production of glass products, and the intermediate film can be reused as a resin material.

図１は、本発明の分離装置１０の実施例の全体構成を示す図である。この分離装置は、剥離機１２と分別機１４とを備えている。剥離機１２の前段には、合わせガラスを破砕する破砕装置１６が設けられているが、この破砕装置は、分離装置の構成要素ではない。   FIG. 1 is a diagram showing an overall configuration of an embodiment of a separation apparatus 10 of the present invention. This separation device includes a peeling machine 12 and a sorting machine 14. Although the crushing device 16 for crushing the laminated glass is provided in the front stage of the peeling machine 12, this crushing device is not a component of the separation device.

この分離装置１０では、破砕機１６で破砕されたガラス片が中間膜に付着した状態の合わせガラス（以下、破砕合わせガラスという）を、剥離機１２に投入する。剥離機１２では、中間膜から大部分のガラス片を剥離する。一部のガラス片が剥離されないで依然として付着している中間膜は、取り出しコンベア１８で剥離機１２から排出され、投入コンベア２０で、分別機１４のホッパまで運ばれて、分別機１４に投入され、ガラス片と中間膜とが完全に分離され、分別されて取り出される。   In this separation apparatus 10, laminated glass (hereinafter referred to as crushed laminated glass) in a state where the glass pieces crushed by the crusher 16 are attached to the intermediate film is put into the peeling machine 12. In the peeling machine 12, most glass pieces are peeled from the intermediate film. The intermediate film that is not peeled off and is still adhered is discharged from the peeling machine 12 by the take-out conveyor 18, transported to the hopper of the sorting machine 14 by the loading conveyor 20, and thrown into the sorting machine 14. The glass piece and the intermediate film are completely separated, separated and taken out.

図２に剥離機１２の構造を示す。図は、内部構造の理解を容易にするため、構造の一部を切り欠き、および構造の一部を透明として示してある。
剥離機１２は、水槽２２を備えている。この水槽２２内には剥離剤としてスルファミン酸，リン酸，フッ素イオンを含む化合物、およびサリチル酸メチルの少なくとも1種を含む水溶液を入れる。水溶液としては、アルカリ性処理希釈液（例えば、水素イオン濃度ｐＨ11のアルカリ性処理水）または界面活性剤を含む水溶液であってもよい。水溶液は、水槽２２に設けられた複数個のヒータ２４によって所定温度に加熱される。
剥離機１２は、さらに金属製の回転円筒状ドラム２６を備えている。このドラム２６は、回転可能に支持されるが、支持機溝については本発明の特徴ではないので図示していない。 FIG. 2 shows the structure of the peeling machine 12. In the figure, in order to facilitate understanding of the internal structure, a part of the structure is cut out and a part of the structure is shown as transparent.
The peeling machine 12 includes a water tank 22. An aqueous solution containing at least one of sulfamic acid, phosphoric acid, a compound containing fluorine ions, and methyl salicylate is placed in the water tank 22 as a release agent. The aqueous solution may be an alkaline treatment diluent (for example, alkaline treatment water having a hydrogen ion concentration of pH 11) or an aqueous solution containing a surfactant. The aqueous solution is heated to a predetermined temperature by a plurality of heaters 24 provided in the water tank 22.
The peeling machine 12 further includes a metal rotating cylindrical drum 26. The drum 26 is rotatably supported, but the support groove is not shown because it is not a feature of the present invention.

円筒状ドラム２６の円周側面には、所定の間隔をおいて多数個の穴２８があけられている。穴からは後述するように中間膜から剥離されたガラス片が水槽２２内に落下する。
ドラム２６の内面には、ドラムの断面図である図３に示すように、ボルト状の突起４０が適当な間隔をあけて多数個設けられている。 A large number of holes 28 are formed at predetermined intervals on the circumferential side surface of the cylindrical drum 26. As will be described later, the glass piece peeled off from the interlayer film falls into the water tank 22 from the hole.
As shown in FIG. 3 which is a cross-sectional view of the drum, a large number of bolt-shaped protrusions 40 are provided on the inner surface of the drum 26 at appropriate intervals.

回転円筒状ドラム２６は、入口３０と出力３２とを有し、出口３２の周囲には、ギア３４が設けられている。ギヤ３４に噛み合う歯車３６が設けられ、この歯車３６を、モータ３８により回転駆動することにより、ドラム２６が回転される。
ドラム２６の入り口３０からは、破砕機１６から破砕合わせガラス４２が投入されるが、投入を容易にするために、傾斜滑り台４４がドラム２６の入口付近に設けられている。傾斜滑り台４４に対する破砕合わせガラス４２の滑りをよくするため、傾斜滑り台上には、バルブ４６から水を流し、流水を形成する。
一方、ドラム２６の出口３２には、大部分のガラス片が剥離された中間膜４３を取り上げるコンベア１８が設けられている。 The rotating cylindrical drum 26 has an inlet 30 and an output 32, and a gear 34 is provided around the outlet 32. A gear 36 that meshes with the gear 34 is provided, and the drum 26 is rotated by rotationally driving the gear 36 by a motor 38.
The shredded laminated glass 42 is fed from the crusher 16 through the entrance 30 of the drum 26, but an inclined slide 44 is provided near the entrance of the drum 26 in order to facilitate the feeding. In order to improve the slip of the crushed laminated glass 42 with respect to the inclined slide 44, water is flowed from the valve 46 on the inclined slide to form flowing water.
On the other hand, an exit 32 of the drum 26 is provided with a conveyor 18 that picks up the intermediate film 43 from which most of the glass pieces have been peeled off.

ドラム２６の下部は、水槽２２内の水溶液に浸漬され、かつ、ドラム２６の下方には、ドラムの穴２８から落下してくるガラス片４８を受ける傾斜受け台５０が配置されている。
図４は傾斜受け台５０を示す斜視図である。この受け台は、ドラム２６の入り口３０から出口３２に向かって下がるように傾斜しており、受け台５０上のガラス片を傾斜方向に移動させるための水流を作る噴水管５２が設けられている。この噴水管には、水を噴出させる噴水口５４が複数個設けられている。この傾斜受け台５０の排出口付近にはガラス片を集めるガイド５６が設けられており、このガイド内に真空ポンプ５８が配置されている。なお、図では構造の理解を助けるために、ガイドを透明状態で示してある。 A lower part of the drum 26 is immersed in the aqueous solution in the water tank 22, and an inclined cradle 50 is disposed below the drum 26 to receive the glass piece 48 falling from the hole 28 of the drum.
FIG. 4 is a perspective view showing the inclined cradle 50. The cradle is inclined so as to descend from the entrance 30 of the drum 26 toward the exit 32, and a fountain pipe 52 is provided to create a water flow for moving the glass piece on the cradle 50 in the tilt direction. . The fountain pipe is provided with a plurality of fountain ports 54 through which water is ejected. A guide 56 for collecting glass pieces is provided in the vicinity of the discharge port of the inclined cradle 50, and a vacuum pump 58 is disposed in the guide. In the figure, the guide is shown in a transparent state to help understand the structure.

以上のような構造の剥離機１２において、破砕合わせガラス４２は、傾斜滑り台４４を経て、回転するドラム２６内に投入されている。投入された破砕合わせガラス４２は、回転するドラムの突起４０に引っ掛けられて、破砕合わせガラスを下部から上部へ持ち上げた状態から、下部へ落下する。このような動作が繰り返されて、破砕合わせガラス４２はドラム内で揉みほぐされ、ドラム下部における入り口３０から出口３２への水流によって、出口側へと移動していく。この間に剥離剤がガラス片４８と中間膜４３との間に浸透し、この工程および後工程でのガラス膜の剥離を容易にする。
ドラム２６内での破砕合わせガラス４２の揉みほぐし動作によって、大部分のガラス片４８は中間膜４３から剥離し、ドラム２６の穴２８から受け部５０に落下する。 In the peeling machine 12 having the above structure, the crushed laminated glass 42 is put into the rotating drum 26 through the inclined slide 44. The crushed laminated glass 42 that has been thrown is caught by the protrusion 40 of the rotating drum, and falls from the state in which the crushed laminated glass is lifted from the lower part to the upper part. By repeating such an operation, the crushed laminated glass 42 is loosened in the drum, and moves toward the outlet side by the water flow from the inlet 30 to the outlet 32 in the lower part of the drum. During this time, the release agent permeates between the glass piece 48 and the intermediate film 43, facilitating the peeling of the glass film in this step and the subsequent step.
Most of the glass pieces 48 are peeled off from the intermediate film 43 by the crushing and unraveling operation of the crushed laminated glass 42 in the drum 26 and fall to the receiving portion 50 from the hole 28 of the drum 26.

なお、この剥離工程において、回転する円筒状ドラム２６内に破砕合わせガラスとともに適当個数の鉄片を加えると、これら鉄片が破砕合わせガラスと接触して、ガラス片の剥離が増進する。   In this peeling step, when an appropriate number of pieces of iron are added together with the crushed laminated glass in the rotating cylindrical drum 26, these pieces of iron come into contact with the crushed laminated glass, and the peeling of the glass pieces is promoted.

積水管５２から噴射される水流によって、ガラス片４８は受け部５０上をガイド５６側へ移動する。ガイド５６に貯まったガラス片４８は、真空ポンプ５６で水溶液と共に吸い上げられ、パイプ５９を経て図５に示す回収水槽６０内のメッシュ袋６２に排出される。ガラス片４８はメッシュ袋に集められ、水溶液は水槽６０に貯まる。水槽の水溶液は水槽外のポンプ６４により吸い出されて、図２の剥離機１２の噴水管５２に経て、水槽２２に戻される。噴水管のみならず、噴水ノズル４６にも戻してもよい。   The glass piece 48 moves on the receiving portion 50 toward the guide 56 due to the water flow ejected from the reservoir pipe 52. The glass pieces 48 stored in the guide 56 are sucked up together with the aqueous solution by the vacuum pump 56, and are discharged to the mesh bag 62 in the recovery water tank 60 shown in FIG. The glass pieces 48 are collected in a mesh bag, and the aqueous solution is stored in the water tank 60. The aqueous solution in the water tank is sucked out by a pump 64 outside the water tank, and returned to the water tank 22 through the fountain pipe 52 of the peeling machine 12 in FIG. Not only the fountain pipe but also the fountain nozzle 46 may be returned.

以上のように剥離機１２の工程で中間膜から大部分のガラス片が剥離されるが、一部のガラス片は中間膜４３に依然として付着したままである。このような中間膜４３は、取り出しコンベア１８で回転ドラム２６から取り出されて、投入コンベア２０ヘ運ばれ、次工程の分別機１４へ送られる。   As described above, most of the glass pieces are peeled off from the intermediate film in the process of the peeling machine 12, but some of the glass pieces are still attached to the intermediate film 43. Such an intermediate film 43 is taken out from the rotary drum 26 by the take-out conveyor 18, transported to the input conveyor 20, and sent to the separator 14 in the next process.

図６に分別機１４を示す。この分別機は、残された付着ガラス片４８を中間膜４３から完全に分離して、ガラス片と中間膜を分別するためのものである。なお、図６において、内部構造の理解を容易にするため、構造の一部を透明として示してある。   FIG. 6 shows the sorter 14. This sorter is for completely separating the remaining adhered glass piece 48 from the intermediate film 43 to separate the glass piece from the intermediate film. In FIG. 6, a part of the structure is shown as transparent for easy understanding of the internal structure.

この分別機１４は、円筒容器７０を備え、円筒容器７０の上部には、投入コンベア２０で運ばれてきた中間膜４３を投入するホッパ７２が設けられている。なお、円筒容器７０は、内部の構造の理解を容易にするため、透明状態で示してある。   This sorter 14 includes a cylindrical container 70, and a hopper 72 for introducing the intermediate film 43 carried by the input conveyor 20 is provided on the upper part of the cylindrical container 70. The cylindrical container 70 is shown in a transparent state in order to facilitate understanding of the internal structure.

円筒容器７０の内部には、羽根車７６が設けられている。図７は、羽根車７６を示す図である。羽根車７６は、回転軸７５に、互いに直角をなして４枚の平板状羽根７４が固定されている。この羽根車７６は、図示しないモータによって回転される。   An impeller 76 is provided inside the cylindrical container 70. FIG. 7 is a view showing the impeller 76. The impeller 76 has four flat blades 74 fixed to a rotating shaft 75 at right angles to each other. The impeller 76 is rotated by a motor (not shown).

円筒容器７０の上部内面には、複数の進行リブ７８が設けられている。進行リブは、3ケ月状の金属片であり、羽根車７６の回転軸７５の方向に対して斜めに平行に設けられており、後述するように羽根車７６で振り回されている中間膜４３を羽根車７６の回転軸方向に移動させる働きをする。   A plurality of advance ribs 78 are provided on the upper inner surface of the cylindrical container 70. The advancing rib is a crescent-shaped piece of metal, and is provided obliquely and parallel to the direction of the rotation shaft 75 of the impeller 76, and the intermediate film 43 swung around by the impeller 76 as will be described later. It works to move in the direction of the rotational axis of the impeller 76.

円筒容器７０の内部下方には、半円筒上の金属製の穴あき板が設けられている。穴あき板８０の穴８２からは後述するように剥離されたガラス片４８が落下する、円筒容器７０の下部は、落下してくるガラス片を外部へ排出する２個の下部スリット８４，８６を有しており、これらの下部スリットの下には、ガラス片回収箱９０，９２がそれぞれ配置される。   A metal perforated plate on a semi-cylinder is provided below the inside of the cylindrical container 70. A glass piece 48 peeled off from the hole 82 of the perforated plate 80 falls as described later. The lower part of the cylindrical container 70 has two lower slits 84 and 86 for discharging the falling glass piece to the outside. The glass piece collection boxes 90 and 92 are respectively disposed below these lower slits.

円筒容器７０のホッパ例とは反対側に、中間膜の出口ダクト９４が設けられている。出口ダクト９４の下側には、水槽９６が設けられている。
以上のような構造の分別機１４のホッパ７２に昇降コンベア２０で運ばれてきた、一部のガラスが付着している中間膜４３を投入すると、中間膜は羽根車７６の羽根７４に引っ掛けられて、遠心力の力で、進行リブ７８および穴あき半円筒状板８０に回転しなから押し付けられる。 An outlet duct 94 for an intermediate film is provided on the opposite side of the cylindrical container 70 from the hopper example. A water tank 96 is provided below the outlet duct 94.
When the intermediate film 43 to which a part of glass is adhered is introduced into the hopper 72 of the sorter 14 having the above-described structure, the intermediate film is hooked on the blades 74 of the impeller 76. Then, it is pressed against the advance rib 78 and the perforated semi-cylindrical plate 80 by the force of centrifugal force without rotating.

進行リブ７８は、回転軸方向に対して斜めに取り付けられているので、羽根車７６の回転とともに、中間膜４３は出力ダクト９４の方へ押しやられていく。また、中間膜は穴あき半円筒状板８０に押しつけられ、こすられるので、中間膜に付着しているガラス片４８は、半円筒状板８０の穴８２に引っ掛かって中間膜４３から剥離される。剥離されたガラス片４８は、穴８２から落下し、スリット８４，８６を経て回収場箱９０，９２に集められる。   Since the advancing rib 78 is attached obliquely with respect to the rotational axis direction, the intermediate film 43 is pushed toward the output duct 94 as the impeller 76 rotates. Further, since the intermediate film is pressed against the perforated semicylindrical plate 80 and rubbed, the glass piece 48 adhering to the intermediate film is caught in the hole 82 of the semicylindrical plate 80 and peeled off from the intermediate film 43. . The peeled glass piece 48 falls from the hole 82 and is collected in the collection box 90, 92 through the slits 84, 86.

また中間膜４３は、出口ダクト９４から、水槽９６に落下する。中間膜をこのように水槽９６に回収する理由は、分別機１４の中で、中間膜にはガラス粉末は付着し汚れるため、水槽に落とし込んで水洗いする必要があるからである。水洗いした中間膜は、袋に入れて保管する。   The intermediate film 43 falls from the outlet duct 94 to the water tank 96. The reason for recovering the intermediate film in the water tank 96 in this manner is that in the separator 14, glass powder adheres to the intermediate film and becomes dirty, so it is necessary to drop it into the water tank and wash it with water. Store the washed interlayer film in a bag.

以上、本発明の一実施例を説明したが、本発明は実施例に限定されるものではなく、本発明の範囲内で種々の変形，変更が可能なことはもちろんである。例えば、剥離機と分別機とは、搬入コンベアで連絡することなく、剥離機の後段に直接に分別機を設けてもよい。また、水溶液とガラス片を分離して回収する回収水槽６０は、剥離機１２と一体に構成してもよい。   As mentioned above, although one Example of this invention was described, this invention is not limited to an Example, Of course, a various deformation | transformation and change are possible within the scope of the present invention. For example, the separating machine and the separating machine may be provided directly at the subsequent stage of the peeling machine without contacting with the carry-in conveyor. Further, the recovery water tank 60 that separates and recovers the aqueous solution and the glass piece may be configured integrally with the peeling machine 12.
