　そして、従来のガラスリサイクル方法としては、シート或いはフィルム付き廃棄ガラスを再利用するためのガラスリサイクル方法であって、 廃棄ガラスを破砕し、破砕されたガラス片をサイズが異なる少なくとも２つのガラス片にふるい選別し、ふるい選別されたガラス片の一部を再利用ガラスとして回収し、ふるい選別されたガラス片の他の一部とシートあるいはフィルム片とを風力選別し、風力選別されたガラス片を再利用ガラスとして回収するようにしたリサイクル方法が知られている。 The conventional glass recycling method is a glass recycling method for reusing waste glass with a sheet or a film, in which the waste glass is crushed and the crushed glass pieces are divided into at least two glass pieces having different sizes. Sifted and collected a part of the screened glass piece as recycled glass, wind-sorted the other part of the screened glass piece and the sheet or film piece, and wind-sorted the glass piece. A recycling method is known in which the glass is collected as recycled glass.
　また、建設複合廃材から骨材を分離回収する方法として、比重の差が殆どない骨材とガラス成分に対して、骨材とガラス成分の破砕強度の差を利用して摩鉱によりガラス成分を骨材より微粉化させて分級し骨材を回収する方法が知られている。 In addition, as a method of separating and recovering aggregates from construction composite waste materials, glass components are separated by ore by utilizing the difference in crushing strength between aggregates and glass components with respect to aggregates and glass components with almost no difference in specific gravity. A method is known in which the aggregate is pulverized from the aggregate, classified, and the aggregate is recovered.

　次に、図８、図９、図１１および図１２に示すように、偏心リング２５による下側ロール２Ｂの昇降について説明すると、下側ロール２Ｂの左右の軸受２３Ｂの外周部分は、偏心リング２５に囲まれて支持された構造となっており、そして、偏心リング２５を回転させることで下側ロール２Ｂおよび軸受２３Ｂの高さ位置が変更するようになされている。また、偏心リング２５が設けられている円形基盤２６の外周側部分にはギア２７が形成され、該外周ギア２７はピニオン２８と噛合し、ピニオン２８はストッパとしてのラック２９と噛合している。 Next, as shown in FIGS. 8, 9, 11 and 12, the raising and lowering of the lower roll 2B by the eccentric ring 25 will be described. The outer peripheral portions of the left and right bearings 23B of the lower roll 2B are the eccentric ring 25. The structure is supported by being surrounded by, and the height positions of the lower roll 2B and the bearing 23B are changed by rotating the eccentric ring 25. Further, a gear 27 is formed on the outer peripheral side portion of the circular base 26 provided with the eccentric ring 25, and the outer peripheral gear 27 meshes with the pinion 28, and the pinion 28 meshes with the rack 29 as a stopper.
　図中２３ＢＯＣは前記下側ロール２Ｂの軸受２３Ｂの外周を示す。また、３５は下側ロール２Ｂの軸を示し、２ＢＯＣは下側ロール２Ｂの外周を示し、２ＡＯＣは上側ロール２Ａの外周を示す。 In the figure, 23BOC indicates the outer circumference of the bearing 23B of the lower roll 2B. Further, 35 indicates the axis of the lower roll 2B, 2BOC indicates the outer circumference of the lower roll 2B, and 2AOC indicates the outer circumference of the upper roll 2A.
　そして、図１２（ａ）に示す偏心リング２５の偏心ゼロ位置では下側ロール２Ｂの外周２ＢＯＣは上側ロール２Ａの外周２ＡＯＣに最接近し（－２ｍｍ程度）、偏心リング２５の回動に伴う図１２（ｂ）の偏心位置では下側ロール２Ｂの外周２ＢＯＣは上側ロール２Ａの外周２ＡＯＣから少し離れた位置となり（間隔８ｍｍ程度）となり、偏心リング２５の更なる回動に伴う図１２（ｃ）の偏心位置では下側ロール２Ｂの外周２ＢＯＣは上側ロール２Ａの外周２ＡＯＣから大きく離れた位置（間隔１８ｍｍ程度）となる。 Then, at the zero eccentric position of the eccentric ring 25 shown in FIG. 12A, the outer peripheral 2BOC of the lower roll 2B is closest to the outer peripheral 2AOC of the upper roll 2A (about -2 mm), and the figure accompanying the rotation of the eccentric ring 25. At the eccentric position of 12 (b), the outer peripheral 2BOC of the lower roll 2B is located slightly away from the outer peripheral 2AOC of the upper roll 2A (interval of about 8 mm), and FIG. 12 (c) shows that the eccentric ring 25 is further rotated. At the eccentric position of, the outer peripheral 2BOC of the lower roll 2B is located at a position (interval of about 18 mm) significantly separated from the outer peripheral 2AOC of the upper roll 2A.
　そして、前述した通り、前記偏心リング２５が設けられている円形基盤２６の外周ギア２７とピニオン２８とが噛合しており、また該ピニオン２８はストッパとして機能するラック２９と噛合している構造であるため、ストッパであるラック２９がピニオン２８の回動を阻止し、これに伴って該ピニオン２８と噛合する円形基盤２６の外周ギア２７も回動せず、その結果、円形基盤２６と一体の前記偏心リング２５も回動せず、これに伴って下側ロール２Ｂの高さ位置が一定に保たれ、この状態で軸受２３Ｂを介してモータＭ２により下側ロール２Ｂが回動することとなる。一方、ラック２９を移動させて該ラック２９とピニオン２８との噛合を解除することで円形基盤２６および偏心リング２５は回動自在となって、該偏心リング２５を回動させることで再び下側ロール２Ｂの高さ位置が変更され、所定の高さ位置で再びラック２９とピニオン２８を噛合させることで下側ロール２Ｂの高さ位置が固定されることとなる。 Then, as described above, the outer gear 27 of the circular base 26 provided with the eccentric ring 25 and the pinion 28 are meshed with each other, and the pinion 28 is meshed with the rack 29 functioning as a stopper. Therefore, the rack 29, which is a stopper, prevents the pinion 28 from rotating, and the outer gear 27 of the circular base 26 that meshes with the pinion 28 does not rotate accordingly, and as a result, it is integrated with the circular base 26. The eccentric ring 25 also does not rotate, and the height position of the lower roll 2B is kept constant accordingly, and in this state, the lower roll 2B is rotated by the motor M2 via the bearing 23B. .. On the other hand, by moving the rack 29 to disengage the engagement between the rack 29 and the pinion 28, the circular base 26 and the eccentric ring 25 become rotatable, and by rotating the eccentric ring 25, the lower side is again. The height position of the roll 2B is changed, and the height position of the lower roll 2B is fixed by engaging the rack 29 and the pinion 28 again at a predetermined height position.
　なお、図中３１は円形基盤２６の内周部分に一体に固定された表示盤であって、表面に下側ロール２Ｂの高さ位置を示す目盛３２が付されており、３３は目盛３２の指示部材である。 In the figure, 31 is a display board integrally fixed to the inner peripheral portion of the circular base 26, and a scale 32 indicating the height position of the lower roll 2B is attached to the surface, and 33 is the scale 32. It is an indicator member.
　また、図１１に示すように、前記円形基盤２６の上方には上側ロール２Ａのスプロケット２２ＡおよびチェーンＣＨが位置している。 Further, as shown in FIG. 11, the sprocket 22A and the chain CH of the upper roll 2A are located above the circular base 26.
　次に、図３～図７に示すように、本実施形態に係る板ガラス破砕機の使用要領について説明すると、先ず、前方へ向かって回転している後側ローラコンベア１１Ｂ上に作業者（図示せず）が太陽光パネルガラスＳＧを背中合わせで二枚載せると、該太陽光パネルガラスＳＧは後側ローラコンベア１１Ｂ上を進んで、破砕機本体１０における上側ロール２Ａと下側ロール２Ｂ間に挟み込まれて圧潰されつつ、前側ローラコンベア１１Ａ上に出てくる。そして、太陽光パネルガラスＳＧの後端が上側ロール２Ａと下側ロール２Ｂ間に達した時点で前後のローラコンベア１１Ａ・１１Ｂ並びに上側ロール２Ａと下側ロール２Ｂを逆回転させて、太陽光パネルガラスＳＧを再び上側ロール２Ａと下側ロール２Ｂ間に挟み込ませて再度圧潰させる。このような太陽光パネルガラスＳＧの上下ロール２Ａ・２Ｂに対する往復移動によって太陽光パネルガラスＳＧにおける前記上下ロール２Ａ・２Ｂの圧接部分での破砕がより綿密に行われる。そして、次に、前記往復移動させた太陽光パネルガラスＳＧを再度、上側ロール２Ａと下側ロール２Ｂへ送る際には、前述した、ずらし装置３０を作動させて、後側ローラコンベア１１Ｂを左右方向に１／２ピッチだけずらせて上下ロール２Ａ・２Ｂに太陽光パネルガラスＳＧを挟み込ませることで、太陽光パネルガラスＳＧおける前記往復移動で直接的圧潰されなかった部分も直接的に圧潰されるため、太陽光パネルガラスＳＧの全面についてより多く細かな破砕が実行される（図６、図７参照）。なお、図中ＢＳは太陽光パネルガラスＳＧのバックシートを示す。
［比較試験］   　 Next, as shown in FIGS. 3 to 7, the procedure for using the flat glass crusher according to the present embodiment will be described. First, an operator (shown) is placed on the rear roller conveyor 11B rotating forward. When two solar panel glass SGs are placed back to back, the solar panel glass SG advances on the rear roller conveyor 11B and is sandwiched between the upper roll 2A and the lower roll 2B in the crusher main body 10. While being crushed, it comes out on the front roller conveyor 11A. Then, when the rear end of the solar panel glass SG reaches between the upper roll 2A and the lower roll 2B, the front and rear roller conveyors 11A and 11B and the upper roll 2A and the lower roll 2B are rotated in the reverse direction to rotate the solar panel. The glass SG is sandwiched between the upper roll 2A and the lower roll 2B again and crushed again. By such reciprocating movement of the solar panel glass SG with respect to the upper and lower rolls 2A and 2B, the solar panel glass SG is more closely crushed at the pressure-welded portion of the upper and lower rolls 2A and 2B. Next, when the reciprocated solar panel glass SG is sent to the upper roll 2A and the lower roll 2B again, the shift device 30 described above is operated to move the rear roller conveyor 11B to the left and right. By sandwiching the solar panel glass SG between the upper and lower rolls 2A and 2B by shifting the direction by 1/2 pitch, the part of the solar panel glass SG that was not directly crushed by the reciprocating movement is also directly crushed. Therefore, more fine crushing is performed on the entire surface of the solar panel glass SG (see FIGS. 6 and 7). In the figure, BS indicates a back sheet of solar panel glass SG.

　次に、前述したガラスカレットの粉砕機５２とプレダスタ５４からなるガラス粉砕装置５１の詳細について説明すると、 Next, the details of the glass crusher 51 including the above-mentioned glass cullet crusher 52 and the preduster 54 will be described.
　図１９～図２１に示すように、本実施形態に係るガラス粉砕装置５１は、予め破砕されたガラスカレットを粉砕する粉砕用ロータ５６が内蔵されたドラム部５３を有する粉砕機５２と、粉砕機５２から斜め上方に伸び、前記ドラム部５３内で粉砕されたガラスを誘導する略直線状の搬送用パイプ６０と、搬送用パイプ６０の上端が挿入された容器状のプレダスタ５４と、プレダスタ５４の下部に一体的に設けられたホッパ５５を有している。なお、図中７０は、粉砕対象である前記破砕されたガラスカレットの投入口を示す。また、前記ドラム部５３の内周面にはライナ５７として複数の円弧状耐摩耗性鋼板がボルト５８およびナット５９で固定されている。 As shown in FIGS. 19 to 21, the glass crusher 51 according to the present embodiment includes a crusher 52 having a drum portion 53 having a crushing rotor 56 for crushing a pre-crushed glass cullet, and a crusher. A substantially linear transport pipe 60 extending diagonally upward from 52 and guiding crushed glass in the drum portion 53, a container-shaped preduster 54 into which the upper end of the transport pipe 60 is inserted, and a preduster 54. It has a hopper 55 integrally provided at the lower part. In the figure, 70 indicates a slot for the crushed glass cullet to be crushed. Further, a plurality of arcuate wear-resistant steel plates are fixed as liners 57 on the inner peripheral surface of the drum portion 53 with bolts 58 and nuts 59.
　なお、本実施形態において、粉砕機５２に対する搬送用パイプ６０の傾斜角度αは約６０°である。 In the present embodiment, the inclination angle α of the transport pipe 60 with respect to the crusher 52 is about 60 °.
　前記プレダスタ５４は、前記搬送用パイプ６０の上端６０ａと対向し、且つ搬送用パイプ６０の軸線に対して所定角度傾斜した反射板６１を有しており、搬送用パイプ６０から吐出した砂状ガラス粉は前記反射板６１に衝突してプレダスタ５４内へ投入され、更に反射板６１に衝突した後の砂状ガラス粉ＧＳはプレダスタ５４内の垂下受板９１に受け止められてスムーズに落下し、前記ホッパ５５内に投入される。また、プレダスタ５４内に充満しているパウダー状ガラス粉ＧＰはプレダスタ５４の上部に連結されているチャンバー９５内に流入した後、ダクト９４およびバタフライダンパー９３を経由して前記捕集機９２内に捕集される（図１９、図２０参照）。本実施形態において、捕集機９２はバグフィルタ等を具備する集塵機能を備えたものであり、当該捕集機９２に捕集されたパウダー状のガラス粉は、ホッパ５５に集積される砂状ガラス粉と同様、資材としてリサイクルされ得る。 The preduster 54 has a reflecting plate 61 that faces the upper end 60a of the transport pipe 60 and is inclined at a predetermined angle with respect to the axis of the transport pipe 60, and is a sandy glass discharged from the transport pipe 60. The powder collides with the reflecting plate 61 and is thrown into the preduster 54, and the sandy glass powder GS after colliding with the reflecting plate 61 is received by the hanging receiving plate 91 in the predaster 54 and falls smoothly, and the powder is smoothly dropped. It is thrown into the hopper 55. Further, the powdery glass powder GP filled in the predaster 54 flows into the chamber 95 connected to the upper part of the predaster 54, and then enters the collector 92 via the duct 94 and the butterfly damper 93. Collected (see FIGS. 19 and 20). In the present embodiment, the collector 92 is provided with a dust collecting function including a bug filter and the like, and the powdery glass powder collected by the collector 92 is sand-like accumulated in the hopper 55. Like glass powder, it can be recycled as a material.
　図２０に示すように、より詳細には、砂状ガラス粉ＧＳは自重でホッパ５５内へ落下し、比重が非常に軽いパウダー状ガラスＧＰだけが捕集機９２に吸引されることとなる。なお、図中６２はプレダスタ５４内を目視するための窓を示す。 As shown in FIG. 20, more specifically, the sandy glass powder GS falls into the hopper 55 by its own weight, and only the powdery glass GP having a very light specific gravity is sucked into the collector 92. In the figure, 62 shows a window for visually observing the inside of the preduster 54.
　図２１～図２４に示すように、粉砕用ロータ５６は、中心に回転駆動軸６３の軸受６４を有する円形基板６６と、円形基板６６の一面に放射状に設けられた複数の粉砕板６７と、各粉砕板６７の端部を周回するように全粉砕板６７の端部に装着されたリング状板６８を備えている。 As shown in FIGS. 21 to 24, the crushing rotor 56 includes a circular substrate 66 having a bearing 64 of a rotary drive shaft 63 in the center, and a plurality of crushing plates 67 radially provided on one surface of the circular substrate 66. A ring-shaped plate 68 attached to the end of the entire crushed plate 67 is provided so as to orbit the end of each crushed plate 67.
　図２３～図２６に示すように、前記ドラム部５３の中央部分には前記回転駆動軸６３が突出しており、回転駆動軸６３に粉砕用ロータ５６の軸受６４が嵌め合わされて止めナット７１によって固定されており、かかる構造によって、粉砕用ロータ５６が回転自在に軸支されている。 As shown in FIGS. 23 to 26, the rotary drive shaft 63 projects from the central portion of the drum portion 53, and the bearing 64 of the crushing rotor 56 is fitted to the rotary drive shaft 63 and fixed by the stop nut 71. The crushing rotor 56 is rotatably supported by such a structure.
　粉砕用ロータ５６が内蔵されたドラム部５３には、内蓋７２が装着され、更に内蓋７２の外側にヒンジ９０を介して扉体７３が取り付けられ、該扉体７３によってドラム部５３が開閉自在となされている。本実施形態では、内蓋７２が粉砕用ロータ５６のリング状板６８と同形となされている。 An inner lid 72 is attached to the drum portion 53 in which the crushing rotor 56 is built, and a door body 73 is attached to the outside of the inner lid 72 via a hinge 90, and the drum portion 53 is opened and closed by the door body 73. It is made free. In this embodiment, the inner lid 72 has the same shape as the ring-shaped plate 68 of the crushing rotor 56.
　この他、図２７および図２８に示すように、本実施形態では、粉砕用ロータ５６の回転駆動軸６３は、一対のプーリ７４Ａ・７４ＢとベルトＢ、軸受８１を介して電動モータＭによって回転する構造となされており、且つその回転は、粉砕用ロータ５６で粉砕された砂状ガラス粉が搬送用パイプ６０内へ誘導されるような回転となされている。また、前記ホッパ５５の下部には篩機７５が設置されている。 In addition, as shown in FIGS. 27 and 28, in the present embodiment, the rotary drive shaft 63 of the crushing rotor 56 is rotated by the electric motor M via a pair of pulleys 74A and 74B, a belt B, and a bearing 81. It has a structure, and its rotation is such that the sandy glass powder crushed by the crushing rotor 56 is guided into the transport pipe 60. A sieving machine 75 is installed below the hopper 55.
　次に、本実施形態に係るガラス粉砕装置５１の使用方法について説明すると、電動モータＭを作動させて粉砕用ロータ５６を回転させた状態で、予め前記破砕機１によって破砕されたガラスカレットＧＣを粉砕機５２の投入口７０から粉砕機５２内に投入することで、該ガラスカレットＧＣが回転している粉砕用ロータ５６の粉砕板６７に衝突して粉砕され、また粉砕板６７に衝突した後のガラスカレットＧＣは、粉砕用ロータ５６を囲むようにドラム部５３内周面に取り付けられている耐摩耗性のライナ５７に衝突することで更に粉砕され、またこのような粉砕状態においてドラム部５３内を飛び交うガラスカレットＧＣ同士が衝突する等して、前記投入口７０から投入される際には鋭利な角があったガラスカレットＧＣは、粉砕されると共に前記鋭利な角も磨耗によって無くなり、最終的に鋭利な角がとれた細かな砂状のガラス粉ＧＳとなる。 Next, a method of using the glass crusher 51 according to the present embodiment will be described. A glass cullet GC crushed in advance by the crusher 1 in a state where the electric motor M is operated to rotate the crushing rotor 56. By charging the glass cullet GC into the crusher 52 from the input port 70 of the crusher 52, the glass cullet GC collides with the crushing plate 67 of the rotating crushing rotor 56 and is crushed, and after colliding with the crushing plate 67. The glass cullet GC is further crushed by colliding with a wear-resistant liner 57 attached to the inner peripheral surface of the drum portion 53 so as to surround the crushing rotor 56, and the drum portion 53 is further crushed in such a crushed state. The glass cullet GC, which had sharp corners when it was thrown in from the slot 70 due to collision between the glass cullet GCs flying inside, was crushed and the sharp corners disappeared due to wear, and finally. It becomes a fine sandy glass powder GS with sharp edges.
　また、前記粉砕用ロータ５６の回転に伴ってドラム部５３内にはガラスカレットＧＣを巻き上げる旋回空気渦流が発生しており、前述した粉砕によって、外形が数ミリ程度にまで粉砕された細かい砂状ガラス粉ＧＳは前記巻き上げ空気渦流によって、搬送用パイプ６０内を上昇してプレダスタ５４へ誘導される。この際、搬送用パイプ６０は、略直接状であるため、前記砂状ガラス粉ＧＣは搬送途中に淀みなく、何らの抵抗もなく、スムーズにプレダスタ５４内に進入する。そして、プレダスタ５４内では、前記搬送用パイプ６０の上端と対向して配設されている傾斜状の反射板６１に、前記進入してきた砂状ガラス粉ＧＳが衝突し、更に反射板６１に、衝突した後の砂状ガラス粉ＧＳは、プレダスタ５４内の垂下受板９１に受け止められて下方に落下し、最終的にプレダスタ５４下方のホッパ５５に前記砂状ガラス粉ＧＳが落下する。そして、砂状ガラス粉ＧＳはホッパ５５から前記篩機７５へ流入する。 Further, a swirling air vortex that winds up the glass cullet GC is generated in the drum portion 53 with the rotation of the crushing rotor 56, and the outer shape is crushed to about several millimeters by the above-mentioned crushing. The glass powder GS rises in the transport pipe 60 and is guided to the preduster 54 by the hoisting air vortex. At this time, since the transport pipe 60 has a substantially direct shape, the sandy glass powder GC smoothly enters the preduster 54 without stagnation during transport and without any resistance. Then, in the preduster 54, the sandy glass powder GS that has entered collides with the inclined reflective plate 61 arranged so as to face the upper end of the transport pipe 60, and further, the reflective plate 61 is subjected to the collision. The sandy glass powder GS after the collision is received by the hanging receiving plate 91 in the preduster 54 and falls downward, and finally the sandy glass powder GS falls on the hopper 55 below the predaster 54. Then, the sandy glass powder GS flows from the hopper 55 into the sieving machine 75.
　一方、ドラム部５３内で十分に粉砕されていないガラスカレットＧＣは、前記粉砕用ロータ５６の回転に伴うドラム部５３内の巻き上げ旋回空気渦流によって上昇せずに自重で落下すると共に再び粉砕用ロータ５６の粉砕板６７に衝突したり、その反動でライナ５７に衝突し、また前記ガラスカレットＧＣ同士の衝突によって更に粉砕化されるのである。そして、このような粉砕化の繰り返しによって外形が数ミリ程度にまで粉砕された細かい砂状ガラス粉ＧＳになった時に、該砂状ガラス粉ＧＳが前記粉砕用ロータ５６の回転に伴うドラム部５３内の巻き上げ旋回空気渦流によって上昇して搬送用パイプ６０内へ導かれるのである。 On the other hand, the glass cullet GC that has not been sufficiently crushed in the drum portion 53 does not rise due to the hoisting swirling air vortex in the drum portion 53 accompanying the rotation of the crushing rotor 56, but falls by its own weight and again the crushing rotor. It collides with the crushed plate 67 of 56, collides with the liner 57 due to the reaction thereof, and is further pulverized by the collision between the glass cullet GCs. Then, when the fine sandy glass powder GS whose outer shape is crushed to about several millimeters is obtained by repeating such crushing, the sandy glass powder GS becomes the drum portion 53 accompanying the rotation of the crushing rotor 56. It rises by the winding swirling air vortex inside and is guided into the transport pipe 60.
　本発明に係るリサイクル方法およびリサイクルシステムによれば、板ガラスから一定粒度の砂状ガラス粉が容易且つ確実に得られるため、太陽光パネルガラス、自動車ガラス、窓ガラスおよび遊戯機ガラス等として使用された板ガラスを資源化の分野において、幅広い利用が期待できる。 According to the recycling method and recycling system according to the present invention, since sandy glass powder having a certain particle size can be easily and surely obtained from flat glass, it has been used as solar panel glass, automobile glass, window glass, amusement machine glass and the like. Widespread use of flat glass can be expected in the field of recycling.
