Description

本発明は、板ガラスの製造方法及び板ガラスの折割装置に関するものである。 The present invention relates to a method for producing flat glass and a flat glass folding device.

周知のように、液晶ディスプレイ、プラズマディスプレイ、有機ＥＬディスプレイなどのフラットパネルディスプレイ（ＦＰＤ）用のガラス基板や、有機ＥＬ照明用のカバーガラスに代表されるように、各種分野で板ガラスが利用される。板ガラスの製造工程では、大面積の板ガラス（マザーガラス）から小面積の板ガラスを切り出したり、板ガラスの辺に沿う縁部をトリミングしたりする折割（割断）工程が含まれる。 As is well known, flat glass is used in various fields as represented by glass substrates for flat panel displays (FPDs) such as liquid crystal displays, plasma displays, and organic EL displays, and cover glasses for organic EL lighting. .. The flat glass manufacturing process includes a folding (cutting) step of cutting out a small area flat glass from a large area flat glass (mother glass) and trimming the edge along the side of the flat glass.

折割工程では、折り割る対象となる板ガラスの製品部と非製品部との境界において、板ガラスの第一主面（例えば上面）にスクライブ線を形成した後、そのスクライブ線を中心とした曲げ応力を作用させて板ガラスをスクライブ線に沿って折り割る。 In the folding process, a scribe line is formed on the first main surface (for example, the upper surface) of the plate glass at the boundary between the product part and the non-product part of the plate glass to be folded, and then the bending stress centered on the scribe line. Fold the flat glass along the scribe line.

そして、この折割工程後に、非製品部に吸着パッド等の吸着部材を吸着させることにより、非製品部を取り除く。取り除かれた非製品部は、例えば、吸着部材により廃棄用の搬送路に受け渡され、廃棄口まで移送される（例えば、特許文献１参照）。 Then, after this folding step, the non-product portion is removed by adsorbing a suction member such as a suction pad to the non-product portion. The removed non-product part is, for example, delivered to a transport path for disposal by an adsorption member and transferred to a disposal port (see, for example, Patent Document 1).

国際公開第２０１３／０７３４７７号International Publication No. 2013/073477

ところで、折割工程後に、非製品部に吸着部材を吸着させる際に、非製品部が製品部に接触して製品部に欠けが生じる場合があった。これは、次のような理由によるものである。折割工程では、板ガラスにスクライブ線を中心とした曲げ応力を作用させるために、スクライブ線に対応する位置で、板ガラスの第二主面の側から板ガラスに折割部材を押し込み、板ガラスが折り割られた後も非製品部に吸着部材を吸着させるまで、折割部材の押込み状態を維持する。そのため、非製品部に吸着部材を吸着させるまで、製品部及び非製品部に互いの切断端面が離れるような状態になっている。しかし、従来では、非製品部に吸着部材を吸着させる際に、非製品部が、吸着部材に押されて湾曲し、製品部に接触する場合があり、これにより、製品部に欠けが生じるのである。 By the way, when the suction member is adsorbed to the non-product part after the folding step, the non-product part may come into contact with the product part and the product part may be chipped. This is due to the following reasons. In the folding process, in order to apply bending stress centered on the scribe wire to the plate glass, the folding member is pushed into the plate glass from the side of the second main surface of the plate glass at the position corresponding to the scribe wire, and the plate glass is folded. Even after being squeezed, the folded member is maintained in the pressed state until the suction member is attracted to the non-product portion. Therefore, the cut end faces of the product portion and the non-product portion are separated from each other until the suction member is attracted to the non-product portion. However, conventionally, when the suction member is sucked onto the non-product part, the non-product part may be pushed by the suction member and curved to come into contact with the product part, which causes the product part to be chipped. is there.

本発明は、上記事情に鑑み、板ガラスの折割工程後に、非製品部に吸着部材を吸着させる際に、製品部に欠けが生じる事態を回避することを技術的課題とする。 In view of the above circumstances, it is a technical problem to avoid a situation in which the product portion is chipped when the suction member is adsorbed on the non-product portion after the plate glass folding step.

前記課題を解決するために創案された本発明に係る板ガラスの製造方法は、第一主面に形成されたスクライブ線を境界とする製品部及び非製品部を有する板ガラスを配置する配置工程と、前記板ガラスのうち、前記製品部の前記第一主面を第一押圧部材で押圧し、前記非製品部の前記第一主面を第二押圧部材で押圧した状態で、前記スクライブ線に対応する位置で、前記板ガラスの第二主面の側から前記板ガラスに折割部材を押し込むことにより、前記スクライブ線に沿って前記板ガラスを折り割る折割工程と、前記折割工程後に、前記非製品部に吸着部材の吸着面を吸着させる吸着工程と、前記吸着工程後に、前記非製品部を除去するために前記非製品部を前記吸着部材により移動させる移動工程とを備えた板ガラスの製造方法であって、前記吸着工程で、前記折割部材の押し込み状態を維持することにより、前記製品部及び前記非製品部に互いの切断端面が離れるように傾斜部を形成すると共に、前記吸着部材の前記吸着面が前記非製品部の前記傾斜部に沿うように吸着部材を傾斜させたことを特徴とする。ここで、「傾斜部に沿うように」とは、厳密に傾斜部に沿っている場合だけでなく、傾斜部から多少ずれている場合も含む（以下、同様）。好ましい吸着部材の傾斜角度は、後述する。 The method for manufacturing a plate glass according to the present invention, which was devised to solve the above problems, includes an arrangement step of arranging a plate glass having a product part and a non-product part having a scribing line formed on the first main surface as a boundary. In the flat glass, the first main surface of the product part is pressed by the first pressing member, and the first main surface of the non-product part is pressed by the second pressing member, corresponding to the scribing line. At the position, the folding member is pushed into the plate glass from the side of the second main surface of the plate glass to fold the plate glass along the scribing line, and after the folding step, the non-product portion. It is a method for manufacturing a plate glass including a suction step of adsorbing a suction surface of a suction member and a moving step of moving the non-product part by the suction member in order to remove the non-product part after the suction step. In the suction step, by maintaining the pushed state of the folding member, inclined portions are formed in the product portion and the non-product portion so that the cut end faces are separated from each other, and the suction member is sucked. The suction member is inclined so that the surface is along the inclined portion of the non-product portion. Here, "to follow the inclined portion" includes not only the case of strictly following the inclined portion but also the case of being slightly deviated from the inclined portion (hereinafter, the same applies). The preferred inclination angle of the suction member will be described later.

この構成によれば、吸着部材の吸着部を、非製品部の傾斜部に沿うように傾斜させたため、非製品部に吸着部材を吸着させる際に、非製品部が吸着部材に押されて湾曲することが抑制され、非製品部が製品部に接触して製品部に欠けが生じることを抑制できる。 According to this configuration, since the suction portion of the suction member is tilted along the inclined portion of the non-product portion, the non-product portion is pushed by the suction member and curved when the suction member is attracted to the non-product portion. It is possible to prevent the non-product part from coming into contact with the product part and causing the product part to be chipped.

上記の構成において、前記吸着工程で、前記吸着部材を、前記吸着面の垂線に沿うように接近させて吸着させてもよい。ここで、「垂線に沿うように」とは、厳密に垂線に沿う場合のみだけでなく、垂線から多少ずれている場合も含むものとする（以下、同様）。 In the above configuration, in the suction step, the suction member may be brought close to each other along the perpendicular line of the suction surface and sucked. Here, "to follow the perpendicular line" includes not only the case of strictly following the perpendicular line but also the case of being slightly deviated from the perpendicular line (hereinafter, the same applies).

この構成であれば、非製品部に吸着部材を吸着させる際に、非製品部が吸着部材に押されて湾曲することがさらに抑制され、非製品部が製品部に接触して製品部に欠けが生じることをさらに抑制できる。 With this configuration, when the suction member is attracted to the non-product part, the non-product part is further suppressed from being pushed by the suction member and curved, and the non-product part comes into contact with the product part and is chipped in the product part. Can be further suppressed.

上記の構成において、前記移動工程で、前記吸着部材を、前記吸着面の垂線に沿うように移動させてもよい。 In the above configuration, the suction member may be moved along the perpendicular line of the suction surface in the movement step.

この構成であれば、非製品部を吸着部材により移動させる際に、非製品部が、製品部に接触する可能性を低減できる。 With this configuration, when the non-product part is moved by the suction member, the possibility that the non-product part comes into contact with the product part can be reduced.

上記の構成において、前記吸着部材が、前記第二押圧部材よりも前記製品部の側に配設されていてもよい。 In the above configuration, the suction member may be arranged closer to the product part than the second pressing member.

この構成であれば、吸着部材を、製品部のより近くに配設可能となる。製品部の近くに配設された吸着部材ほど、非製品部が製品部に接触する原因となり易い。そのため、吸着部材の吸着面が傾斜していることによる上述した効果がより有効となり得る。 With this configuration, the suction member can be arranged closer to the product part. The closer the suction member is to the product part, the more likely it is that the non-product part will come into contact with the product part. Therefore, the above-mentioned effect due to the inclined surface of the suction member can be more effective.

上記の構成において、前記吸着部材の前記吸着面の傾斜角度が、変更可能であってもよい。 In the above configuration, the inclination angle of the suction surface of the suction member may be changeable.

ここで、非製品部の寸法等に応じ、折割部材の押し込み状態や第一押圧部材及び第２押圧部材の位置が変更される。この折割り条件の変更に伴い、非製品部の傾斜部の傾斜角度も変化する。吸着部材の吸着面の傾斜角度が変更可能であれば、折割り条件が変更されても、吸着部材の吸着面を非製品部の傾斜部と平行となるように傾斜させることが可能となる。 Here, the pushed state of the folding member and the positions of the first pressing member and the second pressing member are changed according to the dimensions of the non-product portion and the like. Along with this change in the folding condition, the inclination angle of the inclined portion of the non-product portion also changes. If the inclination angle of the suction surface of the suction member can be changed, the suction surface of the suction member can be tilted so as to be parallel to the slope of the non-product portion even if the folding condition is changed.

上記の構成において、前記吸着部材を、前記スクライブ線と垂直かつ前記板ガラスの前記第一主面と平行な方向に並べて複数配置し、前記吸着部材のうちで前記製品部からの距離が最も近い前記吸着部材を傾斜させてもよい。 In the above configuration, a plurality of the suction members are arranged side by side in a direction perpendicular to the scribe line and parallel to the first main surface of the plate glass, and the suction member has the closest distance to the product part. The suction member may be tilted.

製品部からの距離が近くなるほど、非製品部の勾配が大きくなる。このため、製品部からの距離が最も近い吸着部材を傾斜させれば、吸着面が傾斜していることによる上述した効果がより有効となり得る。 The closer the distance from the product part, the greater the gradient of the non-product part. Therefore, if the suction member having the shortest distance from the product part is tilted, the above-mentioned effect due to the tilting of the suction surface can be more effective.

また、前記課題を解決するために創案された本発明に係る板ガラスの折割装置は、第一主面に形成されたスクライブ線を境界とする製品部及び非製品部を有する板ガラスを、前記スクライブ線に沿って前記板ガラスを折り割る板ガラスの折割装置であって、前記板ガラスを配置する配置機構と、前記製品部の前記第一主面を押圧する第一押圧部材と、前記非製品部の前記第一主面を押圧する第二押圧部材と、前記スクライブ線に対応する位置で、前記板ガラスの第二主面の側から前記板ガラスに押し込むと共に、折り割られた前記板ガラスの前記製品部及び前記非製品部に互いの切断端面が離れるように傾斜部を形成する折割部材と、折り割られた前記板ガラスの前記非製品部を除去するために、前記非製品部を吸着すると共に移動させる吸着部材とを備え、前記吸着部材の前記吸着面が前記非製品部の前記傾斜部に沿うように傾斜していることを特徴とする。 Further, the flat glass folding device according to the present invention, which was devised to solve the above problems, uses a flat glass having a product part and a non-product part formed on the first main surface as a boundary with a scrib line. A plate glass folding device for folding the plate glass along a line, the arrangement mechanism for arranging the plate glass, the first pressing member for pressing the first main surface of the product part, and the non-product part. The second pressing member that presses the first main surface and the product part of the plate glass that is pushed into the plate glass from the side of the second main surface of the plate glass and folded at a position corresponding to the scribe line. In order to remove the folded member that forms an inclined portion so that the cut end faces of the non-product portion are separated from each other and the non-product portion of the folded flat glass, the non-product portion is attracted and moved. It is characterized in that the suction member is provided, and the suction surface of the suction member is inclined along the inclined portion of the non-product portion.

この構成によれば、冒頭の板ガラスの製造方法で説明した作用及び効果と、実質的に同様の作用及び効果を得ることができる。 According to this configuration, it is possible to obtain substantially the same action and effect as the action and effect described in the method for producing flat glass at the beginning.

以上のように、本発明によれば、板ガラスの折割工程後に、非製品部に吸着部材を吸着させる際に、製品部に欠けが生じる事態を回避することができる。 As described above, according to the present invention, it is possible to avoid a situation in which the product portion is chipped when the suction member is adsorbed on the non-product portion after the plate glass folding step.

以下、本発明を実施するための形態について図面に基づき説明する。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

図１は、本発明の実施形態に係る板ガラスの折割装置１を示す概略側面図である。折割装置１は、板ガラスＧをスクライブ線Ｓに沿って折り割るものである。 FIG. 1 is a schematic side view showing a flat glass folding device 1 according to an embodiment of the present invention. The folding device 1 folds the flat glass G along the scribe line S.

板ガラスＧは水平姿勢で配置され、スクライブ線Ｓが形成された第一主面Ｇ１が上面、第二主面Ｇ２が下面とされる。板ガラスＧは、スクライブ線Ｓを境界として製品部Ｇａと非製品部Ｇｂとに区画される。 The flat glass G is arranged in a horizontal posture, and the first main surface G1 on which the scribe line S is formed is the upper surface, and the second main surface G2 is the lower surface. The flat glass G is divided into a product section Ga and a non-product section Gb with the scribe line S as a boundary.

板ガラスＧの製品部Ｇａの厚みは、例えば、２ｍｍ以下であり、好ましくは０．２ｍｍ〜０．７ｍｍである。非製品部Ｇｂの図での横方向の寸法は、例えば、３０ｍｍ〜２００ｍｍの範囲で変更される。非製品部Ｇｂには、製品部Ｇａよりも板厚の大きい厚肉部（不図示）が含まれている場合がある。非製品部Ｇｂの厚肉部は、例えば、オーバーフローダウンドロー法やフロート法などを用いて板ガラスＧを成形したときに生じ得る。 The thickness of the product portion Ga of the flat glass G is, for example, 2 mm or less, preferably 0.2 mm to 0.7 mm. The lateral dimension of the non-product portion Gb in the drawing is changed in the range of, for example, 30 mm to 200 mm. The non-product portion Gb may include a thick portion (not shown) having a plate thickness larger than that of the product portion Ga. The thick portion of the non-product portion Gb may occur when the flat glass G is formed by using, for example, an overflow down draw method or a float method.

なお、本実施形態では、便宜上、製品部Ｇａの側を前側とすると共に非製品部Ｇｂの側を後側とする。 In this embodiment, for convenience, the product part Ga side is the front side and the non-product part Gb side is the rear side.

折割装置１は、配置機構２と、押圧機構３と、移動機構４と、折割機構５とを備えている。 The folding device 1 includes an arranging mechanism 2, a pressing mechanism 3, a moving mechanism 4, and a folding mechanism 5.

配置機構２は、板ガラスＧを上方に配置する第一載置台２ａと第二載置台２ｂで構成される。なお、本実施形態では、配置機構２は、載置台であるが、板ガラスＧを上方に配置できればよく、例えば、例えばベルトコンベア、ローラコンベア、ロボットハンド等の搬送機構であってもよい。 The arrangement mechanism 2 is composed of a first mounting table 2a and a second mounting table 2b for arranging the plate glass G upward. In the present embodiment, the arrangement mechanism 2 is a mounting table, but the plate glass G may be arranged above, and may be, for example, a transfer mechanism such as a belt conveyor, a roller conveyor, or a robot hand.

押圧機構３は、第一載置台２ａの上で製品部Ｇａの第一主面Ｇ１を押圧する第一押圧部材３ａを上下方向に昇降可能に備えている。第一押圧部材３ａは、ゴム（弾性部材）から構成されている。ゴムは、板ガラスＧの第二主面Ｇ２に倣って弾性変形するので、板ガラスＧの微妙な動き（変形を含む）にも追従する。ゴムとしては、例えば、天然ゴム、合成ゴムなどが使用できる。なお、弾性部材はゴムに限定されず、スポンジなどであってもよい。 The pressing mechanism 3 is provided with a first pressing member 3a that presses the first main surface G1 of the product portion Ga on the first mounting table 2a so as to be able to move up and down in the vertical direction. The first pressing member 3a is made of rubber (elastic member). Since the rubber elastically deforms following the second main surface G2 of the plate glass G, it follows the delicate movement (including deformation) of the plate glass G. As the rubber, for example, natural rubber, synthetic rubber and the like can be used. The elastic member is not limited to rubber, and may be a sponge or the like.

移動機構４は、上下方向及び横方向に移動可能な移動部４ａを備えている。移動部４ａは、第二載置台２ｂの上で非製品部Ｇｂの第一主面Ｇ１を押圧する第二押圧部材４ｂを有する。移動部４ａに対し、第二押圧部材４ｂは上下方向に昇降可能である。 The moving mechanism 4 includes a moving portion 4a that can move in the vertical direction and the horizontal direction. The moving portion 4a has a second pressing member 4b that presses the first main surface G1 of the non-product portion Gb on the second mounting table 2b. The second pressing member 4b can move up and down with respect to the moving portion 4a.

第二押圧部材４ｂは、第一押圧部材３ａと同様に、ゴム（弾性部材）から構成されている。 The second pressing member 4b is made of rubber (elastic member) like the first pressing member 3a.

また、移動部４ａは、折り割られた板ガラスＧの非製品部Ｇｂに吸着する吸着部材４ｃを有する。本実施形態では、吸着部材４ｃは、吸着パッドであり、スクライブ線Ｓに沿って一列に並べて複数配置されている。また、吸着部材４ｃの吸着面４ｄ（吸着部）は、吸着部材４ｃの先端面であり、非製品部Ｇｂの第一主面Ｇ１と接触する。吸着部材４ｃの吸着面４ｄが、その前側が後側よりも板ガラスＧから離隔するように、傾斜している。詳述すれば、吸着部材４ｃの吸着面４ｄは、その前側が後側よりも高位置となるように、水平面に対して傾斜している。また、吸着部材４ｃは、第二押圧部材４ｂよりも前側に配設されている。 Further, the moving portion 4a has a suction member 4c that is attracted to the non-product portion Gb of the folded flat glass G. In the present embodiment, the suction members 4c are suction pads, and a plurality of suction members 4c are arranged side by side in a row along the scribe line S. Further, the suction surface 4d (suction portion) of the suction member 4c is the tip surface of the suction member 4c and comes into contact with the first main surface G1 of the non-product portion Gb. The suction surface 4d of the suction member 4c is inclined so that the front side thereof is separated from the plate glass G more than the rear side. More specifically, the suction surface 4d of the suction member 4c is inclined with respect to the horizontal plane so that the front side thereof is higher than the rear side. Further, the suction member 4c is arranged on the front side of the second pressing member 4b.

移動部４ａに対し、吸着部材４ｃは、鉛直方向に対して後側に傾斜した方向に沿って移動（昇降）可能である。例えば図２に示すように、吸着部材４ｃは、シリンダ機構６のシリンダロッド６ａに設けられる。シリンダ機構６のシリンダ６ｂには、複数のボルト穴６ｃが設けられており、シリンダ６ｂは、移動部４ａの壁部４ｅに設けられた円弧状の長穴４ｆを介し、ボルト穴６ｃに螺合するボルト（不図示）によって壁部４ｅに固定される。長穴４ｆに対するボルト穴６ｃの位置を変更することにより、シリンダ機構６の中心軸Ａの鉛直方向に対する傾斜角度αを変更することができる。これにより、吸着部材４ｃの吸着面４ｄの水平面Ｈに対する傾斜角度βを変更することができる。なお、シリンダ機構６の中心軸Ａは、吸着部材４ｃの吸着面４ｄの垂線である。 With respect to the moving portion 4a, the suction member 4c can move (up and down) along a direction inclined rearward with respect to the vertical direction. For example, as shown in FIG. 2, the suction member 4c is provided on the cylinder rod 6a of the cylinder mechanism 6. The cylinder 6b of the cylinder mechanism 6 is provided with a plurality of bolt holes 6c, and the cylinder 6b is screwed into the bolt holes 6c via an arcuate elongated hole 4f provided in the wall portion 4e of the moving portion 4a. It is fixed to the wall portion 4e by a bolt (not shown). By changing the position of the bolt hole 6c with respect to the elongated hole 4f, the inclination angle α of the central axis A of the cylinder mechanism 6 with respect to the vertical direction can be changed. Thereby, the inclination angle β of the suction surface 4d of the suction member 4c with respect to the horizontal plane H can be changed. The central axis A of the cylinder mechanism 6 is a perpendicular line of the suction surface 4d of the suction member 4c.

吸着部材４を傾斜させる角度βは、折割り前の板ガラスＧの第１主面Ｇ１の法線と吸着部材４ｃの吸着面４ｄの垂線がなす角度αで、１〜３０°が好ましく、１．５〜１５°がより好ましく、２〜１０°が最も好ましい。吸着部材４ｃは、例えば硬度が３０〜９０のウレタン製である。なお、本実施形態のシリンダ機構６は、傾斜角度α＝０°とすることが可能であり、その場合、中心軸Ａは、鉛直方向に沿う。 The angle β for inclining the suction member 4 is an angle α formed by the normal line of the first main surface G1 of the plate glass G before folding and the perpendicular line of the suction surface 4d of the suction member 4c, and is preferably 1 to 30 °. 5 to 15 ° is more preferable, and 2 to 10 ° is most preferable. The suction member 4c is made of urethane having a hardness of, for example, 30 to 90. The cylinder mechanism 6 of the present embodiment can have an inclination angle α = 0 °, in which case the central axis A is along the vertical direction.

The folding mechanism 5 is provided with a folding member 5a that pushes up the second main surface G2 of the plate glass G at a position directly below the scribe line S so as to be able to move up and down along the vertical direction. The surfaces of the folding member 5a facing the second main surface G2 are a flat surface portion 5b straddling both sides of the scribe line S and a pair of inclined portions inclined downward so as to be separated from the second main surface G2 on both sides of the flat surface portion 5b. Has 5c and. In the present embodiment, the surface of the folding member 5a facing the second main surface G2 has an isosceles trapezoidal cross-sectional shape.

The angle θ formed by the flat surface portion 5b and the inclined portion 5c is preferably 30 to 50 °.

第一押圧部材３ａ、第二押圧部材４ｂ及び折割部材５ａは、スクライブ線Ｓに沿う方向に延びた長尺体である。本実施形態では、第一押圧部材３ａ、第二押圧部材４ｂ及び折割部材５ａは、板ガラスＧの全幅に亘って連続的に接触する。なお、本実施形態では、第一押圧部材３ａ、第二押圧部材４ｂ及び折割部材５ａは、板ガラスＧの全幅よりも長いが、これらの部材３ａ，４ｂ，５ａの少なくとも一つが、板ガラスＧの全幅と同じ長さであってもよいし、短い長さであってもよい。また、第一押圧部材３ａ、第二押圧部材４ｂ及び折割部材５ａの少なくとも一つが、幅方向で板ガラスＧと断続的に接触してもよい。 The first pressing member 3a, the second pressing member 4b, and the folding member 5a are elongated bodies extending in the direction along the scribe line S. In the present embodiment, the first pressing member 3a, the second pressing member 4b, and the folding member 5a are in continuous contact with each other over the entire width of the flat glass G. In the present embodiment, the first pressing member 3a, the second pressing member 4b, and the folding member 5a are longer than the total width of the plate glass G, but at least one of these members 3a, 4b, 5a is made of the plate glass G. It may be the same length as the full width, or it may be a short length. Further, at least one of the first pressing member 3a, the second pressing member 4b, and the folding member 5a may intermittently contact the flat glass G in the width direction.

次に、以上のように構成された折割装置１を用いた本実施形態に係る板ガラスの製造方法を説明する。 Next, a method for manufacturing a flat glass according to the present embodiment using the folding device 1 configured as described above will be described.

図３に示すように、本実施形態に係る板ガラスの製造方法は、スクライブ線形成工程Ｓ１と、配置工程Ｓ２と、折割工程Ｓ３と、吸着工程Ｓ４と、移動工程Ｓ５とを備える。 As shown in FIG. 3, the method for manufacturing a flat glass according to the present embodiment includes a scribe line forming step S1, an arranging step S2, a folding step S3, an adsorption step S4, and a moving step S5.

まず、スクライブ線形成工程Ｓ１では、板ガラスＧの第一主面Ｇ１において、製品部Ｇａと非製品部Ｇｂとの境界に対して、ホイールカッターによる押圧やレーザーの照射等によりスクライブ線Ｓを形成する。本実施形態では、板ガラスＧは、矩形状であり、対向する一組の辺（二辺のみ）や各辺（四辺）に平行にスクライブ線Ｓを形成する。スクライブ線Ｓの内側が製品部Ｇａ、スクライブ線Ｓの外側が非製品部Ｇｂとなる。 First, in the scribe line forming step S1, the scribe line S is formed on the first main surface G1 of the flat glass G by pressing with a wheel cutter, irradiating a laser, or the like with respect to the boundary between the product portion Ga and the non-product portion Gb. .. In the present embodiment, the flat glass G has a rectangular shape, and forms a scribe line S parallel to a set of opposing sides (only two sides) and each side (four sides). The inside of the scribe line S is the product part Ga, and the outside of the scribe line S is the non-product part Gb.

そして、配置工程Ｓ２では、図１に示すように、スクライブ線Ｓが形成された板ガラスＧを、第一主面Ｇ１を上方に向けた状態で、配置機構２に配置する。 Then, in the arrangement step S2, as shown in FIG. 1, the plate glass G on which the scribe line S is formed is arranged in the arrangement mechanism 2 with the first main surface G1 facing upward.

その後、折割工程Ｓ３で、図４に示すように、板ガラスＧの第一主面Ｇ１の上方に退避していた第一押圧部材３ａを下降させ、第一押圧部材３ａで製品部Ｇａの第一主面Ｇ１の第一主面Ｇ１を押圧する。また、板ガラスＧの第一主面Ｇ１の上方に退避していた移動部４ａを下降させ所定位置に配置し、更に、移動部４ａに対して第二押圧部材４ｂを下降させ、第二押圧部材４ｂで非製品部Ｇｂの第一主面Ｇ１を押圧する。すなわち、ゴムからなる第一押圧部材３ａで製品部Ｇａの第一主面Ｇ１が保持され、ゴムからなる第二押圧部材４ｂで非製品部Ｇｂの第一主面Ｇ１が保持される。 After that, in the folding step S3, as shown in FIG. 4, the first pressing member 3a retracted above the first main surface G1 of the flat glass G is lowered, and the first pressing member 3a is used to lower the product unit Ga. The first main surface G1 of the one main surface G1 is pressed. Further, the moving portion 4a retracted above the first main surface G1 of the flat glass G is lowered and arranged at a predetermined position, and further, the second pressing member 4b is lowered with respect to the moving portion 4a to lower the second pressing member. The first main surface G1 of the non-product portion Gb is pressed by 4b. That is, the first pressing member 3a made of rubber holds the first main surface G1 of the product part Ga, and the second pressing member 4b made of rubber holds the first main surface G1 of the non-product part Gb.

この状態から、板ガラスＧの下方に退避していた折割部材５ａを上昇させ、図５に示すように、スクライブ線Ｓの直下位置で、板ガラスＧの第二主面Ｇ２を上方に押し上げる。換言すると、スクライブ線Ｓに対応する位置で、板ガラスＧの第二主面Ｇ２の側から板ガラスＧに折割部材５ａを押し込む。これにより、スクライブ線Ｓを中心とする曲げ応力を板ガラスＧに作用させる。この際、スクライブ線Ｓの両側に跨るように、折割部材５ａの平面部５ｂが板ガラスＧの第二主面Ｇ２と接触する。折割部材５ａの上昇量は、板ガラスＧの搬送面（第一載置台２ａ及び第二載置台２ｂの上面）を零基準として上方に、例えば２ｍｍ〜３０ｍｍである。折割部材５ａの上昇量は、非製品部Ｇｂの大きさや板厚によって変化させてもよいし、変化させなくてもよい。 From this state, the folding member 5a retracted below the flat glass G is raised, and as shown in FIG. 5, the second main surface G2 of the flat glass G is pushed upward at a position directly below the scribe line S. In other words, the folding member 5a is pushed into the plate glass G from the side of the second main surface G2 of the plate glass G at a position corresponding to the scribe line S. As a result, bending stress centered on the scribe line S is applied to the plate glass G. At this time, the flat surface portion 5b of the folding member 5a comes into contact with the second main surface G2 of the flat glass G so as to straddle both sides of the scribe line S. The amount of rise of the folding member 5a is, for example, 2 mm to 30 mm upward with respect to the transport surface of the plate glass G (upper surfaces of the first mounting table 2a and the second mounting table 2b). The amount of increase of the folded member 5a may or may not be changed depending on the size and plate thickness of the non-product portion Gb.

板ガラスＧに曲げ応力を作用させると、図５に示すように、スクライブ線Ｓに沿って板ガラスＧが折り割られ、製品部Ｇａと非製品部Ｇｂとが分離される。この際、スクライブ線Ｓの直下方位置で板ガラスＧの第二主面Ｇ２が平面部５ｂによって押し上げられて四点曲げのような荷重態様となる。これにより、スクライブ線Ｓのクラックが真っ直ぐ（垂直）に進展しやすくなる。その結果、製品部Ｇａの切断端面Ｇａ１の後加工を省略又は少なくすることができる。 When a bending stress is applied to the flat glass G, the flat glass G is broken along the scribe line S and the product portion Ga and the non-product portion Gb are separated as shown in FIG. At this time, the second main surface G2 of the plate glass G is pushed up by the flat surface portion 5b at a position directly below the scribe line S, resulting in a load mode such as four-point bending. As a result, the crack of the scribe line S tends to grow straight (vertically). As a result, post-processing of the cut end surface Ga1 of the product part Ga can be omitted or reduced.

製品部Ｇａと非製品部Ｇｂとが分離された後も、折割部材５ａは上昇状態（押し込み状態）を維持する。つまり、折割部材５ａを押し込んだままの状態にする。このとき、製品部Ｇａの切断端面Ｇａ１と非製品部Ｇｂの切断端面Ｇｂ１との間は折割部材５ａの平面部５ｂによって押し広げられ、製品部Ｇａの切断端面Ｇａ１と非製品部Ｇｂの切断端面Ｇｂ１とが互いに離れた状態となる。また、製品部Ｇａに傾斜部Ｇａ２が形成されると共に、非製品部Ｇｂに傾斜部Ｇｂ２が形成される。製品部Ｇａの傾斜部Ｇａ２と非製品部Ｇｂの傾斜部Ｇｂ２は、配置工程Ｓ２の板ガラスＧに対して上方に傾斜した状態である。 Even after the product part Ga and the non-product part Gb are separated, the folding member 5a maintains the raised state (pushed state). That is, the folding member 5a is kept pushed in. At this time, the space between the cut end surface Ga1 of the product part Ga and the cut end surface Gb1 of the non-product part Gb is expanded by the flat surface portion 5b of the folding member 5a, and the cut end surface Ga1 of the product part Ga and the non-product part Gb are cut. The end faces Gb1 are separated from each other. Further, the inclined portion Ga2 is formed in the product portion Ga, and the inclined portion Gb2 is formed in the non-product portion Gb. The inclined portion Ga2 of the product portion Ga and the inclined portion Gb2 of the non-product portion Gb are in a state of being inclined upward with respect to the plate glass G in the arrangement step S2.

この状態で、吸着工程Ｓ４では、図６に示すように、非製品部Ｇｂの第一主面Ｇ１の上方の所定位置に配置されたままの移動部４ａに対して、吸着部材４ｃを下降させる。そして、吸着部材４ｃで非製品部Ｇｂの第一主面Ｇ１を吸着保持する。換言すると、吸着部材４ｃの吸着面４ｄを、その垂線（中心軸Ａ）に沿うように非製品部Ｇｂの第一主面Ｇ１に接近させて吸着させる。 In this state, in the suction step S4, as shown in FIG. 6, the suction member 4c is lowered with respect to the moving portion 4a which is still arranged at a predetermined position above the first main surface G1 of the non-product portion Gb. .. Then, the suction member 4c sucks and holds the first main surface G1 of the non-product portion Gb. In other words, the suction surface 4d of the suction member 4c is brought close to the first main surface G1 of the non-product portion Gb along its perpendicular line (central axis A) and is sucked.

吸着部材４ｃの吸着面４ｄは、非製品部Ｇｂの傾斜部Ｇｂ２を吸着する。そして、吸着部材４ｃの吸着面４ｄは、非製品部Ｇｂの傾斜部Ｇｂ２の第一主面Ｇ１に沿うように傾斜している。なお、吸着部材４ｃが非製品部Ｇｂに接近する方向は、折割部材５ａの押込方向（鉛直方向）に対して後側に傾斜している。 The suction surface 4d of the suction member 4c sucks the inclined portion Gb2 of the non-product portion Gb. The suction surface 4d of the suction member 4c is inclined along the first main surface G1 of the inclined portion Gb2 of the non-product portion Gb. The direction in which the suction member 4c approaches the non-product portion Gb is inclined to the rear side with respect to the pushing direction (vertical direction) of the folding member 5a.

非製品部Ｇｂの第一主面Ｇ１上における吸着部材４ｃの最も前側の吸着位置と、非製品部Ｇｂの第一主面Ｇ１の前側端との距離は、３０ｍｍ以内が好ましく、２０ｍｍ以内がより好ましく、１５ｍｍ以内が最も好ましい。 The distance between the frontmost suction position of the suction member 4c on the first main surface G1 of the non-product part Gb and the front end of the first main surface G1 of the non-product part Gb is preferably 30 mm or less, more preferably 20 mm or less. It is preferably within 15 mm, and most preferably within 15 mm.

移動工程Ｓ５では、図７に示すように、吸着部材４ｃの吸着保持の後、移動部４ａに対して第二押圧部材４ｂを上昇させる。その後、図８に示すように、移動部４ａに対して、非製品部Ｇｂを吸着した状態で吸着部材４ｃを上昇させる。詳述すると、吸着部材４ｃの吸着面４ｄを、その垂線（中心軸Ａ）に沿うように移動させる。この際、吸着部材４ｃの移動方向は、折割部材５ａの押込方向（鉛直方向）に対して後側に傾斜している。 In the moving step S5, as shown in FIG. 7, after the suction and holding of the suction member 4c, the second pressing member 4b is raised with respect to the moving portion 4a. After that, as shown in FIG. 8, the suction member 4c is raised with the non-product part Gb sucked to the moving part 4a. More specifically, the suction surface 4d of the suction member 4c is moved along its perpendicular line (central axis A). At this time, the moving direction of the suction member 4c is inclined to the rear side with respect to the pushing direction (vertical direction) of the folding member 5a.

次に、図９に示すように、吸着部材４ｃが非製品部Ｇｂを吸着保持した状態で、移動部４ａが斜め後側に上昇する。これらの動作により、第二載置台２ｂ上から非製品部Ｇｂが除去される。また、移動部４ａが斜め後側に上昇を開始すると同時又は後に折割部材５ａは下降して待機位置に戻る。 Next, as shown in FIG. 9, the moving portion 4a rises diagonally to the rear side in a state where the suction member 4c sucks and holds the non-product portion Gb. By these operations, the non-product portion Gb is removed from the second mounting table 2b. Further, when the moving portion 4a starts to rise diagonally to the rear side, the folding member 5a descends at the same time or later and returns to the standby position.

第二載置台２ｂ上から取り除かれた非製品部Ｇｂは、移動部４ａの移動により、廃棄用の搬送路上に移動させられる。そこで、吸着部材４ｃの吸着保持が解除され、非製品部Ｇｂは搬送路により廃棄場所に搬送されることになる。 The non-product portion Gb removed from the second mounting table 2b is moved onto the transport path for disposal by the movement of the moving portion 4a. Therefore, the suction holding of the suction member 4c is released, and the non-product portion Gb is transported to the disposal site by the transport path.

以上のように構成された本実施形態の製造方法では、以下の効果を享受できる。 The manufacturing method of the present embodiment configured as described above can enjoy the following effects.

吸着部材４ｃの吸着面４ｄを、非製品部Ｇｂの傾斜部Ｇｂ２に沿うように傾斜させたため、非製品部Ｇｂに吸着部材４ｃを吸着させる際に、非製品部Ｇｂが吸着部材４ｃに押されて湾曲することが抑制され、非製品部Ｇｂが製品部Ｇａに接触して製品部Ｇａに欠けが生じることを抑制できる。 Since the suction surface 4d of the suction member 4c is inclined along the inclined portion Gb2 of the non-product portion Gb, the non-product portion Gb is pushed by the suction member 4c when the suction member 4c is attracted to the non-product portion Gb. It is possible to prevent the non-product part Gb from coming into contact with the product part Ga and causing the product part Ga to be chipped.

本発明は、上記実施形態に限定されるものでは無く、その技術的思想の範囲内で、様々な変形が可能である。例えば、吸着部材４ｃは、スクライブ線Ｓと垂直かつ板ガラスＧの第一主面Ｇ１と平行な方向にも並べて複数配置されてもよい。この場合、吸着部材４ｃは、スクライブ線Ｓに沿って複数列に並べて配置される。これにより、幅が広い非製品部Ｇｂも吸着して除去できる。 The present invention is not limited to the above embodiment, and various modifications can be made within the scope of its technical idea. For example, a plurality of suction members 4c may be arranged side by side in a direction perpendicular to the scribe line S and parallel to the first main surface G1 of the flat glass G. In this case, the suction members 4c are arranged side by side in a plurality of rows along the scribe line S. As a result, the wide non-product portion Gb can also be adsorbed and removed.

折割部材５ａの押し込み時、幅が広い非製品部Ｇｂでは、製品部Ｇａに近くなるに従って勾配が大きくなる。このため、吸着部材４ｃを複数列に並べて配置する場合、最前列に配置された吸着部材４ｃの吸着面４ｄを傾斜させれば、非製品部Ｇｂの湾曲を抑制する効果が顕著となる。このため、製品部Ｇａからの距離が最も近い吸着部材４ｃを傾斜させることが好ましい。また、残りの吸着部材４ｃは、傾斜させないことが好ましい。 When the folding member 5a is pushed in, in the non-product portion Gb having a wide width, the gradient becomes larger as it gets closer to the product portion Ga. Therefore, when the suction members 4c are arranged side by side in a plurality of rows, if the suction surface 4d of the suction members 4c arranged in the front row is inclined, the effect of suppressing the bending of the non-product portion Gb becomes remarkable. Therefore, it is preferable to incline the suction member 4c having the shortest distance from the product part Ga. Further, it is preferable that the remaining suction member 4c is not tilted.

また、上記実施形態では、吸着部材４ｃは、吸着パッドから構成されていたが、吸着部材４ｃは、負圧を利用するものに限定されず、例えば、静電チャックのように、静電気等を利用するものであってもよい。 Further, in the above embodiment, the suction member 4c is composed of a suction pad, but the suction member 4c is not limited to one that uses negative pressure, and uses static electricity or the like, for example, like an electrostatic chuck. It may be something to do.

また、上記実施形態では、水平姿勢の板ガラスＧに対して折割り等の一連の処理を行ったが、これに限定されず、縦姿勢や傾斜姿勢に配置された板ガラスＧに対して折割り等の一連の処理を行ってもよい。 Further, in the above embodiment, a series of processes such as folding the flat glass G in the horizontal posture are performed, but the present invention is not limited to this, and the flat glass G arranged in the vertical posture or the inclined posture is folded or the like. You may perform a series of processing of.

また、上記実施形態では、吸着工程Ｓ４で吸着部材４ｃを非製品部Ｇｂに接近させる際に、吸着部材４ｃを吸着面４ｄの垂線に沿って移動させていたが、上下方向（折割り前の板ガラスＧの第１主面Ｇ１の法線方向）に移動させてもよい。非製品部Ｇｂの湾曲をさらに抑制する観点では、吸着部材４ｃの移動方向を傾斜させることが好ましく、吸着面４ｄの垂線と吸着部材４ｃの移動方向が一致することがより好ましい。 Further, in the above embodiment, when the suction member 4c is brought close to the non-product portion Gb in the suction step S4, the suction member 4c is moved along the vertical line of the suction surface 4d, but in the vertical direction (before folding). It may be moved in the normal direction of the first main surface G1 of the plate glass G). From the viewpoint of further suppressing the curvature of the non-product portion Gb, it is preferable to incline the moving direction of the suction member 4c, and it is more preferable that the vertical line of the suction surface 4d and the moving direction of the suction member 4c match.

また、上記実施形態では、移動工程Ｓ５で、移動部４ａに対して吸着部材４ｃを上昇させてから、移動部４ａを移動させていたが、移動部４ａに対して吸着部材４ｃを上昇させずに、移動部４ａを上昇移動させてもよい。 Further, in the above embodiment, in the moving step S5, the suction member 4c is raised with respect to the moving portion 4a and then the moving portion 4a is moved, but the suction member 4c is not raised with respect to the moving portion 4a. In addition, the moving unit 4a may be moved upward.

また、上記実施形態では、移動部４ａに対して吸着部材４ｃを上昇させる際、及び、移動部４ａを移動させる際のいずれでも、吸着面４ｄの垂線に沿って移動させていたが、上下方向（折割り前の板ガラスＧの第１主面Ｇ１の法線方向）に移動させてもよい。非製品部Ｇｂが製品部Ｇａと接触する可能性を低減する観点では、吸着部材４ｃ及び移動部４ａの移動方向を傾斜させることが好ましく、吸着面４ｄの垂線と吸着部材４ｃの移動方向が一致することがより好ましい。 Further, in the above embodiment, both when the suction member 4c is raised with respect to the moving portion 4a and when the moving portion 4a is moved, the suction member 4c is moved along the vertical line of the suction surface 4d, but in the vertical direction. It may be moved in the normal direction of the first main surface G1 of the flat glass G before folding. From the viewpoint of reducing the possibility that the non-product part Gb comes into contact with the product part Ga, it is preferable to incline the moving directions of the suction member 4c and the moving part 4a, and the vertical line of the suction surface 4d and the moving direction of the suction member 4c match. It is more preferable to do so.

また、上記実施形態では、移動部４ａが、第二押圧部材４ｂを備えていたが、第二押圧部材４ｂは移動部４ａとは別に配設されていてもよい。 Further, in the above embodiment, the moving portion 4a is provided with the second pressing member 4b, but the second pressing member 4b may be arranged separately from the moving portion 4a.

また、上記実施形態では、第一押圧部材３ａと第二押圧部材４ｂが共にゴムから構成されていたが、これに限定されるものではない。例えば、第一押圧部材３ａと第二押圧部材４ｂが共にブラシ状部材で構成されていてもよいし、第一押圧部材３ａと第二押圧部材４ｂのいずれか一方がブラシ状部材で構成されていてもよい。ブラシの毛は弾性を有し、製品部Ｇａの第一主面Ｇ１に倣って撓む。すなわち、ブラシの毛は、板ガラスＧの微妙な動き（変形を含む）にも追従する。ブラシの毛は、例えば、ナイロンなどの樹脂製繊維から形成される。 Further, in the above embodiment, both the first pressing member 3a and the second pressing member 4b are made of rubber, but the present invention is not limited to this. For example, the first pressing member 3a and the second pressing member 4b may both be composed of a brush-shaped member, or either one of the first pressing member 3a and the second pressing member 4b is composed of a brush-shaped member. You may. The bristles of the brush have elasticity and bend according to the first main surface G1 of the product part Ga. That is, the bristles of the brush follow the delicate movement (including deformation) of the plate glass G. The bristles of the brush are formed from resin fibers such as nylon.
