Description

薄板ガラス材の分断装置Thin glass material cutting device
　本発明は、板状に成形された薄板ガラス材の幅方向端部を分断して所定寸法の薄板ガラスを得るための分断装置に関する。 The present invention relates to a cutting apparatus for cutting a width direction end portion of a thin glass material formed into a plate shape to obtain a thin glass having a predetermined size.
　従来、ディスプレイガラスや種々の電子機器におけるカバーガラス等に薄板ガラス（この明細書及び特許請求の範囲の書類中では、これらディスプレイガラス、カバーガラス等を総称して「薄板ガラス」という）が用いられている。 Conventionally, thin glass has been used for display glass and cover glass in various electronic devices (in the specification and claims, these display glass and cover glass are collectively referred to as “thin glass”). ing.
　このような薄板ガラスの製造方法としては、一般的にフロート法とフュージョン法が採用されている。フロート法は、ガラス素地が溶融スズで満たされたフロートバスに供給され、この溶融スズの上に浮かんだ状態のガラス素地が板状に成形される。一方、フュージョン法は、ガラス素地がフュージョンパイプに供給され、このフュージョンパイプからオーバーフローしたガラス素地が下方へ引っ張られながら板状に成形される。このような製造方法で形成される薄板ガラス材としては、例えば、厚みが１ｍｍ以下の薄板に形成される。 As a method for producing such a thin glass, a float method and a fusion method are generally employed. In the float process, the glass substrate is supplied to a float bath filled with molten tin, and the glass substrate floating on the molten tin is formed into a plate shape. On the other hand, in the fusion method, a glass substrate is supplied to a fusion pipe, and the glass substrate overflowed from the fusion pipe is formed into a plate shape while being pulled downward. As a thin glass material formed by such a manufacturing method, for example, it is formed into a thin plate having a thickness of 1 mm or less.
　そして、このような製造方法によって板状に成形された薄板ガラス材は、所定の長さ寸法に分断された後、両幅方向端部が分断されて所定の幅寸法の薄板ガラスとなる。なお、この明細書及び特許請求の範囲の書類中では、薄板ガラス材の搬送方向を「長さ方向」、その搬送方向と直交する方向を「幅方向」とする。 And the thin glass material shape | molded in plate shape by such a manufacturing method is divided | segmented into a predetermined | prescribed length dimension, Then, both width direction edge parts are parted, and it becomes a thin sheet glass of a predetermined | prescribed width dimension. In the specification and claims, the transport direction of the thin glass material is referred to as “length direction”, and the direction orthogonal to the transport direction is referred to as “width direction”.
　この種の先行技術として、フロート法によって製造される帯状の薄板ガラスに切筋線を付与し、その切筋線の内側を支持用ローラーで支持し、切筋線の外側を押し割りローラーで下方に押して薄板ガラスの耳部（幅方向端部）を切断する耳部切断装置において、耳部を押し割りローラーの外側で下方から支持する耳部支持ローラーを設けたものがある（例えば、特許文献１参照）。 As this type of prior art, a scoring line is applied to a strip-shaped thin glass plate manufactured by the float process, the inside of the scoring line is supported by a supporting roller, and the outside of the scoring line is lowered downward by a split roller. In an ear cutting device that pushes and cuts the ear (width direction end) of the thin glass, there is an ear support roller that supports the ear from the lower side outside the split roller (for example, see Patent Document 1). ).

　しかしながら、上記したフロート法やフュージョン法によって形成される薄板ガラス材は、その幅方向端部（耳部）に厚みの安定しない部分（以下、「ビード部」という）が生じる。そのため、上記特許文献１に記載の発明では、この幅方向端部を支持用ローラーで下方から支持しながら上方から押し割りローラーで切断して除去している。 However, the thin glass material formed by the above-described float method or fusion method has a portion (hereinafter referred to as “bead portion”) where the thickness is not stable at the end portion (ear portion) in the width direction. Therefore, in the invention described in Patent Document 1, the width direction end is supported by a supporting roller from below and is removed by cutting with a split roller from above.
　しかし、特許文献１に記載の装置は、薄板ガラス材を支持用ローラーと耳部支持用ローラーで下方から支持し、そのローラーの間を上方から１つの押し割りローラーで押して幅方向端部を剪断するように切断するものであるため、端縁を綺麗に切断するのは難しい。しかも、薄板ガラス材を搬送しながら上方から押して切断するので、幅方向端部が製品となる部分に接触して傷を付けるおそれがある。 However, the apparatus described in Patent Document 1 supports a thin glass material from below with a support roller and an ear support roller, and presses between the rollers with a single split roller from above to shear the end in the width direction. Therefore, it is difficult to cut the edge neatly. Moreover, since the thin glass material is pushed and cut from above while being transported, there is a risk that the end in the width direction may come into contact with the part to be the product and be damaged.
　また、引用文献１に記載の装置は、フロート法によって成形された薄板ガラスのように、薄板ガラス材を搬送しながら切断する場合には適用できるが、フュージョン法によって形成された薄板ガラス材のように、製造時に下方へ引っ張ることで下端部に大きなビード部（しずく状に固まった部分）が形成され、長さ方向が所定寸法に切断加工された薄板ガラス材の幅方向端部を所定位置で分断する場合には適用できない。 Moreover, although the apparatus described in the cited document 1 can be applied when cutting a thin glass material while being transported, such as a thin glass formed by a float method, it is like a thin glass material formed by a fusion method. In addition, by pulling downward at the time of manufacture, a large bead portion (a portion solidified in a drop shape) is formed at the lower end portion, and the end portion in the width direction of the thin glass material whose length direction is cut into a predetermined dimension is set at a predetermined position. It is not applicable when dividing.
　さらに、近年、より薄い板ガラスの要求があり、その薄い板ガラスの端部に形成されるビード部を安定して分断して、所定の大きさの薄板ガラスを得ることができる分断装置が要望されている。 Furthermore, in recent years, there has been a demand for thinner glass sheets, and there has been a demand for a cutting apparatus that can stably sever the bead portion formed at the end of the thin glass sheet to obtain a thin glass sheet of a predetermined size. Yes.
　そこで、本発明は、端部にビード部が形成された薄板ガラス材でも、そのビード部を含むガラス材端部を安定して分断して所定寸法の薄板ガラスを得ることができる分断装置を提供することを課題とする。 Therefore, the present invention provides a cutting apparatus capable of obtaining a thin glass plate having a predetermined size by stably dividing the glass material end portion including the bead portion even in a thin glass material having a bead portion formed at the end portion. The task is to do.
　この課題を解決するために、本発明は、所定長さの薄板ガラス材を下方から支持して所定位置に配置する搬送機と、前記搬送機の所定位置に配置した薄板ガラス材の幅方向におけるガラス材端部を下方から支持した状態と幅方向外方に退避した状態とに変位可能な退避ローラーと、前記薄板ガラス材の幅方向端部において搬送方向に形成する分断ラインの内方位置及び外方位置で該薄板ガラス材を保持する保持機と、前記搬送機に配置した薄板ガラス材の分断ライン位置を下方から支持する切台と、前記切台に対向する位置で薄板ガラス材の上面に所定深さの分断ラインを形成するカッターを具備したスクライブ機と、前記スクライブ機のカッターを上方に退避させ、前記切台を支点に薄板ガラス材のガラス材端部を前記分断ラインで分断する分断機と、前記分断機で分断したガラス材端部を、前記退避ローラーを幅方向外方に退避させて下方へ排出する排出機と、を備えている。 In order to solve this problem, the present invention supports a thin glass material having a predetermined length from below and is arranged at a predetermined position in a width direction of the thin glass material arranged at a predetermined position of the conveying machine.

A scribing machine equipped with a cutter for forming a cutting line of a predetermined depth at the same time, the cutter of the scribing machine is retracted upward, and the glass material end of the thin glass material is cut by the cutting line with the cutting stand as a fulcrum. And that cutting machine, the glass material end which is divided by the dividing unit, and a, a discharger for discharging downwards retracting the retraction roller outwardly in the widthwise direction.
　この構成により、薄板ガラス材を搬送機の所定位置に配置した状態で、その幅方向のガラス材端部の分断位置を下方から切台で支持するとともに、退避ローラーで幅方向のガラス材端部を下方から支持し、切台に対向する薄板ガラス材の上面にスクライブ機のカッターで分断ラインを形成し、カッターを退避させて切台を支点にして薄板ガラス材の幅方向端部を分断ラインで下向きに分断すれば、長さ方向が所定寸法に切断加工された薄板ガラス材の端部に形成されたビード部を含むガラス材端部を下方へ分断して所定寸法の薄板ガラスを得ることができる。しかも、ガラス材端部を分断ラインで板厚保方向に曲げて分断するため、端縁を綺麗に分断することができる。その上、切台によって幅方向のガラス材端部を分断した後、退避ローラーを幅方向外方に退避させることにより、分断した両端部のビード部を含むガラス材端部を製品部分に接触させることなく下方へ排出することができる。 With this configuration, in the state where the thin glass material is arranged at a predetermined position of the transport machine, the dividing position of the glass material end in the width direction is supported from below by the cutting stand, and the glass material end in the width direction is supported by the retracting roller. Is formed on the upper surface of the thin glass material facing the cutting table with a scribing machine cutter, the cutter is retracted and the cutting glass is used as a fulcrum to cut the width direction end of the thin glass material. If it is divided downward, the glass material end portion including the bead portion formed at the end portion of the thin glass material whose length direction is cut into a predetermined dimension is divided downward to obtain a thin glass sheet of the predetermined dimension. Can do. In addition, since the glass material end is bent and divided in the plate thickness maintaining direction along the dividing line, the end edge can be clearly divided. In addition, after the glass material end portion in the width direction is divided by the cutting stand, the end portion of the glass material including the bead portions of the divided both ends is brought into contact with the product portion by retracting the retracting roller outward in the width direction.

　さらに、上記搬送機２０及びスクライブ機５０の外方には、薄板ガラス材１の側方端部を下方から支持する退避ローラー８１と、薄板ガラス材１の端部を上方から押えて保持する分断バー４１とが設けられている。この分断バー４１は、上方に設けられた駆動シリンダ４２によって正確に上下動させられるようになっている。これら退避ローラー８１と分断バー４１は、鉛直方向に対向するように配置されている。この分断バー４１は、薄板ガラス材１の幅方向端部を退避ローラー８１とによって保持する構成でもあり、後述するように、切台３０を突き上げて薄板ガラス材１を分断ラインＬで分断するときに薄板ガラス材１の端部を保持する分断機４０の構成でもある。 Further, on the outside of the transporter 20 and the scribing machine 50, a retracting roller 81 that supports the side end of the thin glass material 1 from below, and a split that holds the end of the thin glass material 1 from above. Bar 41 is provided. The dividing bar 41 can be accurately moved up and down by a drive cylinder 42 provided above. The retracting roller 81 and the dividing bar 41 are arranged to face each other in the vertical direction. This dividing bar 41 is also a structure which hold | maintains the width direction edge part of the thin glass material 1 with the retraction | saving roller 81, and pushes the cutting stand 30 and divides the thin glass material 1 with the dividing line L so that it may mention later. It is also the structure of the parting machine 40 holding the edge part of the thin glass material 1.
　また、退避ローラー８１は、軸を水平方向に向けた状態でローラー部材８２が薄板ガラス材１の幅方向両端部の下面を支持するように配置されている。このローラー部材８２による薄板ガラス材１の支持は、ビード部Ｂ（図１２）の幅方向内方に設定される。 Further, the retracting roller 81 is disposed so that the roller member 82 supports the lower surfaces of both end portions in the width direction of the thin glass material 1 with the shaft oriented in the horizontal direction. The support of the thin glass material 1 by the roller member 82 is set inward in the width direction of the bead portion B (FIG. 12).
　さらに、上記メインフレーム１１の下部には、薄板ガラス材１から分断したガラス材端部２が排出される排出シュート８７が設けられている。この排出シュート８７は、メインフレーム１１に設けられた下部サブフレーム１４に支持されている。上記分断ラインＬで分断されたガラス材端部２は、上記退避ローラー８１を側方に退避させて排出シュート８７に排出される。このガラス材端部２を下方に排出する構成が、排出機８０である。排出シュート８７に排出されたガラス材端部２は、他の機器によって搬出される（図示略）。 Furthermore, a discharge chute 87 for discharging the glass material end 2 separated from the thin glass material 1 is provided at the lower part of the main frame 11. The discharge chute 87 is supported by the lower subframe 14 provided on the main frame 11. The glass material end 2 divided by the dividing line L is discharged to the discharge chute 87 by retracting the retracting roller 81 to the side. A configuration for discharging the glass material end 2 downward is a discharger 80. The glass material end portion 2 discharged to the discharge chute 87 is carried out by another device (not shown).
　図２に示すように、上記メインフレーム１１は、側面視においても門型に形成されている。このメインフレーム１１の搬送方向Ｗのほぼ中心位置に、上記搬送機２０、スクライブ機５０、分断機４０、及び排出機８０が設けられている。そして、この実施形態では、上記各スクライブ機５０に、それぞれ２台のカッターユニット５１が設けられている。この図では、薄板ガラス材１における片方のガラス材端部２に分断ラインＬを形成する１ユニットを示している。 As shown in FIG. 2, the main frame 11 is formed in a gate shape in a side view. The transfer device 20, the scribe device 50, the cutting device 40, and the discharge device 80 are provided at a substantially central position in the transfer direction W of the main frame 11. In this embodiment, each of the scribing machines 50 is provided with two cutter units 51. In this figure, 1 unit which forms the parting line L in the one glass material edge part 2 in the sheet glass material 1 is shown.
　このカッターユニット５１は、スクライブ機５０に設けられたガイドレール６１に沿って薄板ガラス材１の搬送方向Ｗに水平移動可能となっている。ガイドレール６１は、搬送方向Ｗの上流側から下流側まで連続するように設けられたガイドユニット６０の上下部に設けられている。上記カッターユニット５１には、図３にて後述するように、ガイドレール６１に沿って移動するガイド部材６５が設けられている。このガイド部材６５は、ガイドユニット６０に設けられた駆動機６６で駆動されるタイミングベルト６７によって移動させられる。この駆動機６６及びタイミングベルト６７はガイドユニット６０内で上下に並設されており、２台のカッターユニット５１を個別に駆動できるようになっている。ガイドレール６１とガイド部材６５の組合わせとしては、例えば、ＬＭガイド（Linear Motion Guide）が用いられる。 The cutter unit 51 is horizontally movable in the conveyance direction W of the thin glass material 1 along the guide rail 61 provided in the scribe machine 50. The guide rails 61 are provided at the upper and lower portions of the guide unit 60 provided so as to be continuous from the upstream side to the downstream side in the transport direction W. As will be described later with reference to FIG. 3, the cutter unit 51 is provided with a guide member 65 that moves along the guide rail 61. The guide member 65 is moved by a timing belt 67 driven by a driving machine 66 provided in the guide unit 60. The driving machine 66 and the timing belt 67 are arranged side by side in the guide unit 60 so that the two cutter units 51 can be individually driven. As a combination of the guide rail 61 and the guide member 65, for example, an LM guide (Linear Motion Guide) is used.
　また、この実施形態では２台のカッターユニット５１が設けられているため、上記ガイドレール６１をメインフレーム１１の上流側及び下流側から張り出すように延ばすことで、一方のカッターユニット５１を使用しているときに他方のカッターユニット５１を上流側又は下流側の張り出した部分に退避させることができるようになっている。図２では、カッターユニット５１を左方に退避させ、カッター５２を取り外した状態を表している。 Further, in this embodiment, since two cutter units 51 are provided, one cutter unit 51 is used by extending the guide rail 61 so as to project from the upstream side and the downstream side of the main frame 11. The other cutter unit 51 can be retracted to the projecting portion on the upstream side or the downstream side. FIG. 2 shows a state where the cutter unit 51 is retracted to the left and the cutter 52 is removed.
　これにより、一方のカッターユニット５１によって分断ラインＬを加工するときに、他方のカッターユニット５１をガイドユニット６０の上流側又は下流側の張り出し部分に退避させて、そのカッター５２の交換等の作業ができる。従って、カッターユニット５１による分断ラインＬの形成作業を行いながら、消耗品であるカッター５２を交換することなどが可能であり、作業休止時間をなくすことができるようになっている。 As a result, when the cutting line L is processed by one cutter unit 51, the other cutter unit 51 is retracted to the protruding portion on the upstream side or the downstream side of the guide unit 60, and work such as replacement of the cutter 52 is performed. it can. Accordingly, it is possible to replace the cutter 52, which is a consumable item, while performing the forming operation of the dividing line L by the cutter unit 51, and the work downtime can be eliminated.
　なお、ガイドユニット６０を張り出す構成とせずとも、例えばガイドユニット６０に併せてメインフレーム１１の長さ方向寸法も伸ばすなど、カッターユニット５１が実質的に退避できる構成であればよい。 In addition, even if it is not the structure which projects the guide unit 60, it should just be the structure which the cutter unit 51 can evacuate substantially, for example, the length direction dimension of the main frame 11 is extended together with the guide unit 60, for example.
　図３に示すように、上記スクライブ機５０が設けられた上部サブフレーム１３には、上部に左右一対のスクライブ機５０が設けられている。これらのスクライブ機５０は、分断装置１０の中心軸Ｃに対して、以下の構成により左右幅方向に位置調整可能になっている。つまり、上部サブフレーム１３の上面には幅方向に延びるガイドレール６２が設けられ、スクライブ機５０の下部に設けられたガイド部材６３が上記ガイドレール６２に沿って幅方向に移動できるようになっている（例えば、ＬＭガイド）。それぞれのスクライブ機５０は、上部サブフレーム１３に設けられた駆動シリンダ６４によって同期して互いに幅方向逆向きに移動可能となっている。 As shown in FIG. 3, the upper subframe 13 provided with the scribe machine 50 is provided with a pair of left and right scribe machines 50 at the upper part. These scribing machines 50 can be adjusted in position in the left-right width direction with respect to the central axis C of the cutting device 10 by the following configuration. That is, a guide rail 62 extending in the width direction is provided on the upper surface of the upper subframe 13, and the guide member 63 provided in the lower portion of the scribe machine 50 can move in the width direction along the guide rail 62. (For example, LM guide). Each scribe machine 50 is movable in the opposite direction in the width direction in synchronization with a drive cylinder 64 provided in the upper subframe 13.
　また、上述したように、このスクライブ機５０に設けられた上面押え部材７１も一体的に幅方向に移動可能なので（図１）、スクライブ機５０のカッター５２と上面押え部材７１は、幅方向の位置関係を等間隔に保った状態で位置調整可能となっている。 Further, as described above, the upper surface pressing member 71 provided in the scribing machine 50 can also be integrally moved in the width direction (FIG. 1), so that the cutter 52 and the upper surface pressing member 71 of the scribe machine 50 can be moved in the width direction. Position adjustment is possible with the positional relationship kept at regular intervals.
　このように、スクライブ機５０を幅方向に位置調整可能とすることで、後述するように搬送機２０と切台３０とを同時に幅方向に位置調整して、薄板ガラス材１のガラス材端部２を分断する寸法を調整できるようになっている。これにより、ガラス材端部２が分断されて、製品となる薄板ガラス５のサイズを、例えば、数百ミリの範囲で調整することができる。 In this way, by adjusting the position of the scribing machine 50 in the width direction, the position of the conveying machine 20 and the cutting board 30 are simultaneously adjusted in the width direction as will be described later, and the glass material end of the thin glass material 1 The dimension which divides 2 can be adjusted now. Thereby, the glass material edge part 2 is parted and the size of the thin glass 5 used as a product can be adjusted in the range of several hundred millimeters, for example.
　図４に示すように、上記カッターユニット５１は、ユニット枠５４に支持された駆動シリンダ５３と、この駆動シリンダ５３から下方に延びるロッド５５と、このロッド５５の先端に設けられたカッター５２とを有している。ロッド５５は、ガイド部材５６により正確に昇降するようになっており、駆動シリンダ５３によってカッター５２を正確に上下動させることができるようになっている。このカッター５２の上下方向の位置制御としては、例えば、厚みが０．５ｍｍの薄板ガラス材１の場合、一般的にはガラス厚の１０％に相当する０．０５ｍｍの深さで分断ラインＬを形成するため、上記駆動シリンダ５３で正確な上下動制御が行われる。カッター５２としては、例えば、ローラー刃を用いたガラスカッター等が用いられる。 As shown in FIG. 4, the cutter unit 51 includes a drive cylinder 53 supported by a unit frame 54, a rod 55 extending downward from the drive cylinder 53, and a cutter 52 provided at the tip of the rod 55. Have. The rod 55 is raised and lowered accurately by the guide member 56, and the cutter 52 can be moved up and down accurately by the drive cylinder 53. As the vertical position control of the cutter 52, for example, in the case of the thin glass material 1 having a thickness of 0.5 mm, the dividing line L is generally set at a depth of 0.05 mm corresponding to 10% of the glass thickness. For this purpose, accurate vertical movement control is performed by the drive cylinder 53. As the cutter 52, for example, a glass cutter using a roller blade or the like is used.
　また、上記ユニット枠５４は、スクライブ機５０の本体に固定された固定部５８に設けられた移動シリンダ５７によって上下動可能に構成されている。ユニット枠５４にはガイドレール５９が設けられ、このガイドレール５９が固定部５８に沿って上下動するようになっている。移動シリンダ５７によって、ユニット枠５４とともにカッター５２を上方へ大きく移動させることで、カッター５２の点検、交換作業等のための空間が確保できるので、これらが作業性良く容易に行える。 The unit frame 54 is configured to be movable up and down by a moving cylinder 57 provided in a fixed portion 58 fixed to the main body of the scribe machine 50. A guide rail 59 is provided on the unit frame 54, and the guide rail 59 moves up and down along the fixed portion 58. By moving the cutter 52 largely together with the unit frame 54 with the moving cylinder 57, a space for inspection, replacement work, etc. of the cutter 52 can be secured, and these can be easily performed with good workability.
　このように、この実施形態のカッターユニット５１によれば、上記駆動シリンダ５３によってロッド５５を伸長させることで、ロッド５５の下端に設けられたカッター５２を薄板ガラス材１に向けて正確に下降させることができる。 Thus, according to the cutter unit 51 of this embodiment, by extending the rod 55 by the drive cylinder 53, the cutter 52 provided at the lower end of the rod 55 is accurately lowered toward the thin glass material 1. be able to.
　図５に示すように、上記搬送機２０に設けられたベルトコンベヤ２１には、サーボモータ等の駆動モータ２２で駆動されるタイミングベルト２３が使用されている。このベルトコンベヤ２１は、図１に示すように狭い幅寸法のタイミングベルト２３が使用されており、幅方向に４列が設けられている。このベルトコンベヤ２１によれば、駆動モータ２２の角度制御によって薄板ガラス材１を正確な位置に配置することができる。ベルトコンベヤ２１は、支持フレーム２４によって支持され、支持フレーム２４は中間サブフレーム１２に支持されている。 As shown in FIG. 5, a timing belt 23 driven by a drive motor 22 such as a servo motor is used for the belt conveyor 21 provided in the conveyor 20. As shown in FIG. 1, the belt conveyor 21 uses a timing belt 23 having a narrow width dimension, and four rows are provided in the width direction. According to this belt conveyor 21, the thin glass material 1 can be arranged at an accurate position by controlling the angle of the drive motor 22. The belt conveyor 21 is supported by a support frame 24, and the support frame 24 is supported by the intermediate subframe 12.
　また、搬送機２０の幅方向外方に設けられた上記切台３０は、ベルトコンベヤ２１と平行に搬送方向Ｗに延びるように設けられている。この切台３０は、搬送方向前後位置の下部に連結されたロッド３２と、このロッド３２を鉛直方向にガイドするガイド部材３３と、ロッド３２の下端に連結されたＬ字状のリンク材３４と、これらのリンク材３４を連結する連結ロッド３６とによって下方から支持されている。上記リンク材３４は、中央部が支持軸３５で支持されたＬ字状に形成されており、一方のリンク材３４（図示する左側）には、支持軸３５を回転させる駆動モータ３７（例えば、サーボモータ）が設けられている。 Further, the above-mentioned cutting stand 30 provided on the outer side in the width direction of the transport machine 20 is provided so as to extend in the transport direction W in parallel with the belt conveyor 21. This cutting stand 30 includes a rod 32 connected to the lower part of the front and rear position in the transport direction, a guide member 33 for guiding the rod 32 in the vertical direction, and an L-shaped link member 34 connected to the lower end of the rod 32. These are supported from below by a connecting rod 36 that connects these link members 34. The link member 34 is formed in an L shape with a central portion supported by a support shaft 35, and one link member 34 (left side in the drawing) is provided with a drive motor 37 (for example, a rotating shaft 35). Servo motor) is provided.
　従って、上記駆動モータ３７を回転させれば、支持軸３５を介して連結ロッド３６で連結された前後位置のリンク材３３，３４が同期して動作し、搬送方向前後位置のロッド３２を介して切台３０の姿勢を保って上下動させることができる。この切台３０を突き上げて薄板ガラス材１を分断ラインＬで分断する構成も、分断機４０の構成に含まれる。切台３０は、搬送機２０とともに支持フレーム２４によって支持されており、支持フレーム２４は中間サブフレーム１２に支持されている。 Therefore, when the drive motor 37 is rotated, the link members 33 and 34 at the front and rear positions connected by the connection rod 36 via the support shaft 35 operate in synchronization with each other via the rod 32 at the front and rear position in the transport direction. The posture of the cut stand 30 can be maintained and moved up and down. A configuration in which the cutting glass 30 is pushed up to divide the thin glass material 1 along the dividing line L is also included in the configuration of the cutting machine 40. The cut stand 30 is supported by the support frame 24 together with the transporter 20, and the support frame 24 is supported by the intermediate subframe 12.
　また、搬送機２０と切台３０とは、中間サブフレーム１２に設けられたガイドレール２５に沿って、紙面直交方向である幅方向に一体的に移動できる。つまり、搬送機２０と切台３０とは、支持フレーム２４の両側部にガイド部２６が設けられ、これらのガイド部２６とガイドレール２５が係合していることにより位置調整可能となっている。中間サブフレーム１２には、支持フレーム２４を幅方向に移動させる駆動モータ２７が設けられている。 Further, the transporter 20 and the cutting board 30 can move integrally along the guide rail 25 provided in the intermediate subframe 12 in the width direction that is the direction orthogonal to the paper surface. That is, the position of the transporter 20 and the cutting board 30 can be adjusted by providing the guide portions 26 on both sides of the support frame 24 and engaging these guide portions 26 and the guide rails 25. . The intermediate sub-frame 12 is provided with a drive motor 27 that moves the support frame 24 in the width direction.
　このように、搬送機２０と切台３０とを幅方向に位置調整可能とすることで、上述したようにスクライブ機５０を同時に幅方向に位置調整して、薄板ガラス材１のガラス材端部２を分断する寸法を調整できるようになっている。これにより、ガラス材端部２が分断されて製品となる薄板ガラス５のサイズを、例えば、数百ミリの範囲で調整することができる。 As described above, the position of the scribing machine 50 can be simultaneously adjusted in the width direction as described above by adjusting the position of the transfer machine 20 and the cutting board 30 in the width direction, and the glass material end portion of the thin glass material 1 can be adjusted. The dimension which divides 2 can be adjusted now. Thereby, the glass material edge part 2 is parted, and the size of the thin glass 5 used as a product can be adjusted in the range of several hundred millimeters, for example.
　図６に示すように、上記切台３０の上端部には、中央部分に所定深さの凹状部３１が設けられている。この凹状部３１は、切台３０の搬送方向Ｗ（図５）に亘り連続して設けられている。凹状部３１は、薄板ガラス材１の下面に接した状態で、薄板ガラス材１の上面に分断ラインＬを形成するカッター５２によって切台３０の上端部が傷つくことを防ぐために設けられている。この凹状部３１は、カッター５２の刃先厚みよりも幅寸法が広く、カッター５２による分断ラインＬの形成時にカッター下方の薄板ガラス材１が切台３０に接しない深さ寸法で形成されている。 As shown in FIG. 6, a concave portion 31 having a predetermined depth is provided at the center of the upper end portion of the cut stand 30. The concave portion 31 is provided continuously over the conveyance direction W (FIG. 5) of the cutting board 30. The concave portion 31 is provided in order to prevent the upper end portion of the cutting base 30 from being damaged by the cutter 52 that forms the dividing line L on the upper surface of the thin glass material 1 while in contact with the lower surface of the thin glass material 1. The concave portion 31 has a width that is wider than the cutting edge thickness of the cutter 52, and is formed with a depth that does not allow the thin glass material 1 below the cutter to contact the cutting table 30 when the cutting line L is formed by the cutter 52.
　図７に示すように、上記分断機４０は、上部サブフレーム１３に支持されている。上部サブフレーム１３には、搬送機２０のベルトコンベヤ２１によって搬送される薄板ガラス材１の両端部を下方から支持する退避ローラー８１（図１）と、この退避ローラー８１によって支持される薄板ガラス材１を上方から押える分断バー４１とが設けられている。 As shown in FIG. 7, the cutting machine 40 is supported by the upper subframe 13.

　図８に示すように、排出機８０の上記退避ローラー８１は、上部サブフレーム１３に設けられた軸受８３に支持された回転軸８４に設けられている。回転軸８４には、一側方に突出する複数本の支持軸８５が設けられ、これらの支持軸８５の先端部にローラー部材８２がそれぞれ設けられている。回転軸８４は、駆動モータ８６によって回転可能に構成されている。 As shown in FIG. 8, the retracting roller 81 of the discharger 80 is provided on a rotating shaft 84 supported by a bearing 83 provided on the upper subframe 13. The rotation shaft 84 is provided with a plurality of support shafts 85 protruding to one side, and a roller member 82 is provided at the tip of each of the support shafts 85. The rotation shaft 84 is configured to be rotatable by a drive motor 86.

It can be displaced by the displacement angle α to the retracted state retracted outwardly in the width direction from the lower surface. As described later, the displacement angle α is set to an angle at which the glass material end 2 discharged downward does not contact the roller member 82.

The upper surface pressing member 71 includes a support member 75 whose front and rear portions are supported by the drive motor 74 and a plurality of contact members 76 that protrude downward from the support member 75. The contact member 76 is configured to contact the upper surface of the thin glass material 1 with a small area. By making the contact member 76 contact with a small area, the area of the structure contacting the upper surface of the thin glass material 1 is minimized. Further, a cushion material 77 is provided at a portion of the contact member 76 that contacts the thin glass material 1.

Therefore, by driving the drive motor 74, all the contact members 76 can be moved up and down horizontally via the support member 75.
　図１１は、上記した切台３０とスクライブ機５０のカッター５２と、搬送機２０のベルトコンベヤ２１と保持機７０の上面押え部材７１における接触部材７６と、分断機４０（図７）の分断バー４１と排出機８０（図８）の退避ローラー８１におけるローラー部材８２と、の位置関係を示している。図では、分断装置１０の中心線Ｃから左方のみを示している。 11 shows the above-described cutting stand 30, the cutter 52 of the scribing machine 50, the contact member 76 of the upper surface pressing member 71 of the belt conveyor 21 and the holding machine 70 of the transfer machine 20, and the cutting bar of the cutting machine 40 (FIG. 7). The positional relationship between the roller 41 and the roller member 82 of the retracting roller 81 of the discharger 80 (FIG. 8) is shown. In the figure, only the left side from the center line C of the cutting apparatus 10 is shown.
　図１１に示すように、上記切台３０とカッター５２とが、パスラインＰに対し鉛直方向に対向するように配置されている。また、同様に、上記搬送機２０の内方のベルトコンベヤ２１と保持機７０の上面押え部材７１における接触部材７６とも、パスラインＰに対し鉛直方向に対向するように配置されている。さらに、上記分断機４０の分断バー４１と退避ローラー８１のローラー部材８２とも、同様の位置関係にある。 As shown in FIG. 11, the cut stand 30 and the cutter 52 are arranged so as to face the pass line P in the vertical direction. Similarly, the inner belt conveyor 21 of the transport device 20 and the contact member 76 of the upper surface pressing member 71 of the holding device 70 are also arranged so as to face the pass line P in the vertical direction. Further, the cutting bar 41 of the cutting machine 40 and the roller member 82 of the retracting roller 81 are in the same positional relationship.
　そして、上述したように、上記カッター５２と上面押え部材７１と分断バー４１とは、パスラインＰに位置する薄板ガラス材１の上面に向けて下降、または上面から上方に向けて退避させることができるようになっている。また、上記切台３０は、パスラインＰから下方に退避させた状態、パスラインＰの薄板ガラス材１の下面に接する状態、及びパスラインＰから上方に向けて上昇させて薄板ガラス材１を分断ラインＬ（図１２）で分断する状態とに変位させることができるようになっている。 As described above, the cutter 52, the upper surface pressing member 71, and the dividing bar 41 can be lowered toward the upper surface of the thin glass material 1 located on the pass line P, or can be retracted upward from the upper surface. It can be done. In addition, the cut stand 30 is retracted downward from the pass line P, is in contact with the lower surface of the thin glass material 1 of the pass line P, and is lifted upward from the pass line P to raise the thin glass material 1. It can be displaced to a state of being divided at the dividing line L (FIG. 12).
　次に、図１２と図１３Ａ～図１３Ｄに基づいて、以上のように構成された分断装置１０による薄板ガラス材１における幅方向のガラス材端部２を長さ方向に亘り分断する流れを説明する。 Next, based on FIG. 12 and FIGS. 13A to 13D, a flow of dividing the glass material end 2 in the width direction in the thin glass material 1 by the dividing apparatus 10 configured as described above in the length direction will be described. To do.
　まず、図１２に示すように、上流から長さ方向に所定寸法となるように切断加工された薄板ガラス材１が搬送されてくる。そして、この薄板ガラス材１に対し、幅方向両端部に分断ラインＬが形成される。その後、その分断ラインＬでビード部Ｂを含むガラス材端部２を長さ方向に亘って（一点鎖線で図示）分断することで所定の大きさの薄板ガラス５が得られる。以下、この薄板ガラス材１のガラス材端部２を分断する流れを説明する。 First, as shown in FIG. 12, a thin glass material 1 cut to have a predetermined dimension in the length direction is conveyed from upstream. And with respect to this thin glass material 1, the dividing line L is formed in the width direction both ends. Then, the glass sheet end part 2 including the bead part B is divided along the length direction (illustrated by a one-dot chain line) along the parting line L, whereby the thin glass 5 having a predetermined size is obtained. Hereinafter, the flow for dividing the glass material end 2 of the thin glass material 1 will be described.
　まず、図１３Ａに示すように、上流から搬送されてきた薄板ガラス材１が搬送機２０のベルトコンベヤ２１によって所定位置に配置される。 First, as shown in FIG. 13A, the thin glass material 1 that has been transported from the upstream is placed at a predetermined position by the belt conveyor 21 of the transporter 20.
　次に、図１３Ｂに示すように、切台３０が薄板ガラス材１の下面まで上昇させられる。また、上面押え部材７１が下降させられてベルトコンベヤ２１との間で薄板ガラス材１が保持されるとともに、分断バー４１が下降させられて退避ローラー８１との間で薄板ガラス材１が保持される。 Next, as shown in FIG. 13B, the cut stand 30 is raised to the lower surface of the thin glass material 1. Further, the upper surface pressing member 71 is lowered to hold the thin glass material 1 with the belt conveyor 21, and the dividing bar 41 is lowered to hold the thin glass material 1 with the retracting roller 81. The
　この図１３Ｂでは、上述したように、上面押え部材７１に代えて吸引部材７２によって薄板ガラス材１をベルトコンベヤ２１に向けて吸引することで保持する例も示している。上面押え部材７１に代えて吸引部材７２を設けた構成とすれば、製品となる薄板ガラス５の上面（Ａ面）に構造物を接触させることなくガラス材端部２を分断することができ、Ａ面の清潔度を保つことができる。 FIG. 13B also shows an example in which the thin glass material 1 is held by being sucked toward the belt conveyor 21 by the suction member 72 instead of the upper surface pressing member 71 as described above. If the suction member 72 is provided in place of the upper surface pressing member 71, the glass material end portion 2 can be divided without bringing the structure into contact with the upper surface (A surface) of the thin glass 5 serving as a product. A surface can be kept clean.
　その状態で、スクライブ機５０のカッター５２が下降させられて薄板ガラス材１に接触させられる。そして、スクライブ機５０でカッター５２が搬送方向Ｗに送られ、薄板ガラス材１の上面に分断ラインＬが形成される（図１２）。 In this state, the cutter 52 of the scribing machine 50 is lowered and brought into contact with the thin glass material 1. And the cutter 52 is sent to the conveyance direction W with the scribe machine 50, and the parting line L is formed in the upper surface of the sheet glass material 1 (FIG. 12).
　次に、図１３Ｃに示すように、スクライブ機５０のカッター５２が上方に退避させられる。そして、切台３０が突き上げられて、この切台３０を支点にしてビード部を含むガラス材端部２が分断ラインＬに沿って分断される。この分断時、薄板ガラス材１のガラス材端部２に大きなビード部Ｂ（図１２）があったとしても、薄板ガラス材１の幅方向中央部分をベルトコンベヤ２１と上面押え部材７１とで上下方向から保持しているとともに、ガラス材端部２を退避ローラー８１と分断バー４１とで上下方向から保持しているため、分断ラインＬに沿って安定した分断ができる。なお、カッター５２の退避と、切台３０の突き上げとは、少しの時間差でほぼ同時に行うようにすれば、迅速な作業を行うことができる。 Next, as shown in FIG. 13C, the cutter 52 of the scribing machine 50 is retracted upward. Then, the cutting stand 30 is pushed up, and the glass material end 2 including the bead portion is divided along the dividing line L with the cutting stand 30 as a fulcrum. Even when there is a large bead portion B (FIG. 12) at the glass material end 2 of the thin glass material 1 at the time of this division, the belt glass 21 and the upper surface pressing member 71 move the center portion in the width direction of the thin glass material 1 up and down. Since the glass material end 2 is held from above and below by the retracting roller 81 and the cutting bar 41 while being held from the direction, stable cutting along the cutting line L can be performed. In addition, if the retracting of the cutter 52 and the pushing-up of the cutting stand 30 are performed almost simultaneously with a slight time difference, a quick operation can be performed.
　その後、図１３Ｄに示すように、退避ローラー８１が外方に向けて回転させられて、ビード部を含むガラス材端部２が下方へ排出される。 Thereafter, as shown in FIG. 13D, the retracting roller 81 is rotated outward, and the glass material end portion 2 including the bead portion is discharged downward.
　図示しないが、その後、切台３０が下降させられ、上面押え部材７１及び分断バー４１が上昇させられ、退避ローラー８１が薄板ガラス材１を支持する状態に復帰させられる。そして、所定寸法にガラス材端部２が分断された薄板ガラス５が搬出されるとともに、次の薄板ガラス材１が搬入される。以下、上記動作が繰り返される。 Although not shown, the cutting stand 30 is then lowered, the upper surface pressing member 71 and the dividing bar 41 are raised, and the retracting roller 81 is returned to the state of supporting the thin glass material 1. And the thin glass 5 in which the glass material edge part 2 was parted by the predetermined dimension is carried out, and the next thin glass material 1 is carried in. Thereafter, the above operation is repeated.
　以上のように、上記分断装置１０によれば、フュージョン法によって形成された薄板ガラス材１のように、端部に大きなビード部が形成されていたとしても、そのビード部を含むガラス材端部を安定して分断することができるので、薄板ガラス材１を所望の大きさに分断する作業を安定して行うことが可能となる。 As described above, according to the cutting apparatus 10, even if a large bead portion is formed at the end portion as in the thin glass material 1 formed by the fusion method, the end portion of the glass material including the bead portion. Therefore, it is possible to stably perform the operation of dividing the thin glass material 1 into a desired size.
　また、薄板ガラス材１に形成した分断ラインＬを切台３０で下方から上向きに突き上げることで、分断ラインＬからガラス材端部２を幅方向外方に離すように分断し、その分断したガラス材端部２を下方へ排出しているので、製品となる薄板ガラス５の分断部を傷つけることがないように分断することができる。 In addition, by dividing the cutting line L formed on the thin glass material 1 upward from below by the cutting board 30, the glass material end 2 is divided from the dividing line L so as to be separated outward in the width direction, and the divided glass. Since the material edge part 2 is discharged | emitted below, it can divide | segment so that the dividing part of the thin glass 5 used as a product may not be damaged.
　図１４Ａ，図１４Ｂに示す例は、上記図１３Ｃ，図１３Ｄと異なる流れでガラス材端部２を分断する例である。上記図１３Ａと図１３Ｂは同様に行われるため、その説明は省略する。 The examples shown in FIGS. 14A and 14B are examples in which the glass material end 2 is divided by a flow different from that in FIGS. 13C and 13D. Since FIG. 13A and FIG. 13B are performed in the same manner, description thereof is omitted.
　この例では、図１３Ｂに示すように、スクライブ機５０で薄板ガラス材１の上面に分断ラインＬを形成した後、図１４Ａに示すように、スクライブ機５０のカッター５２を上方に退避させた後、退避ローラー８１を幅方向外方に退避させながら、この退避ローラー８１との間で薄板ガラス材１の分断ライン外方を保持している分断バー４１を押し下げる。 In this example, after forming the dividing line L on the upper surface of the thin glass material 1 with the scribe machine 50 as shown in FIG. 13B, the cutter 52 of the scribe machine 50 is retracted upward as shown in FIG. 14A. While the retracting roller 81 is retracted outward in the width direction, the dividing bar 41 holding the outside of the dividing line of the thin glass material 1 is pushed down with the retracting roller 81.
　そして、図１４Ｂに示すように、この分断バー４１の押し下げにより、切台３０を支点にしてビード部を含むガラス材端部２が分断ラインＬに沿って分断される。この分断されたガラス材端部２は、下方へ排出される。 Then, as shown in FIG. 14B, the glass bar end 2 including the bead portion is divided along the dividing line L by using the cutting bar 30 as a fulcrum by pushing down the dividing bar 41. The divided glass material end 2 is discharged downward.
　その後、上面押え部材７１及び分断バー４１が上昇させられ、退避ローラー８１が薄板ガラス材１を支持する状態に復帰させられる。そして、所定寸法にガラス材端部２が分断された薄板ガラス５が搬出されるとともに、次の薄板ガラス材１が搬入される。以下、上記動作が繰り返される。 Thereafter, the upper surface pressing member 71 and the dividing bar 41 are raised, and the retracting roller 81 is returned to the state of supporting the thin glass material 1. And the thin glass 5 in which the glass material edge part 2 was parted by the predetermined dimension is carried out, and the next thin glass material 1 is carried in. Thereafter, the above operation is repeated.
　従って、この例でも、薄板ガラス材１のガラス材端部２に大きなビード部Ｂ（図１２）があったとしても、薄板ガラス材１の幅方向中央部分をベルトコンベヤ２１と上面押え部材７１とで上下方向から保持した状態で、ガラス材端部２を切台３０を支点にして分断するので、ガラス材端部２を分断ラインＬに沿って安定して分断することができる。なお、カッター５２の退避と、退避ローラー８１の退避及び分断バー４１の押し下げは、少しの時間差でほぼ同時に行うようにすれば、迅速な作業を行うことができる。 Therefore, also in this example, even if there is a large bead portion B (FIG. 12) at the glass material end 2 of the thin glass material 1, the belt conveyor 21 and the upper surface pressing member 71 In this state, the glass material end portion 2 is divided using the cutting base 30 as a fulcrum while being held from above and below, so that the glass material end portion 2 can be stably divided along the dividing line L. The retraction of the cutter 52, the retraction of the retraction roller 81, and the pressing down of the dividing bar 41 can be performed quickly if they are performed almost simultaneously with a slight time difference.
　また、切台３０を支点にして薄板ガラス材１に形成した分断ラインＬに沿ってガラス材端部２を幅方向外方に離すように分断し、その分断したガラス材端部２を下方へ排出しているので、製品となる薄板ガラス５の分断部を傷つけることがないように分断することができる。 Moreover, it divides | segments so that the glass material end part 2 may be separated in the width direction outward along the dividing line L formed in the thin glass material 1 by using the cutting stand 30 as a fulcrum, and the divided glass material end part 2 is moved downward. Since it discharges | emits, it can divide | segment so that the dividing part of the thin glass 5 used as a product may not be damaged.
　なお、上記実施形態では、薄板ガラス材１のガラス材端部２を分断する一例を説明したが、搬送機２０及びスクライブ機５０を幅方向に位置調整することで異なる幅寸法の薄板ガラス材１に対応することも可能であり、上記実施形態に限定されるものではない。 In addition, in the said embodiment, although the example which divides | segments the glass material edge part 2 of the sheet glass material 1 was demonstrated, the sheet glass material 1 of a different width dimension by adjusting the position of the conveying machine 20 and the scribe machine 50 to the width direction. It is also possible to correspond to the above, and the present invention is not limited to the above embodiment.
　また、上記実施形態では、駆動機として駆動モータ（サーボモータ）を例に説明しているが、他の構成でも正確に位置制御できる構成であればよく、駆動機の構成は上記実施形態に限定されるものではない。 In the above embodiment, a drive motor (servo motor) is described as an example of the drive machine. However, any other configuration may be used as long as the position can be accurately controlled, and the configuration of the drive machine is limited to the above embodiment. Is not to be done.
　さらに、上記実施形態では、フュージョン法によって形成された薄板ガラス材１を主に説明したが、薄板ガラス材１の製法は特に限定されるものではない。 Furthermore, in the said embodiment, although the thin glass material 1 formed by the fusion method was mainly demonstrated, the manufacturing method of the thin glass material 1 is not specifically limited.
