Description
本発明は、ガラス板等の板材を割断するための割断装置及び板状物品の製造方法に関するものである。 The present invention relates to a cleaving apparatus for cleaving a plate material such as a glass plate and a method for manufacturing a plate-shaped article.
従来、例えば特許文献１に示されるように、大寸のガラス板から所定寸法のガラス小片を得る場合には、まず、大寸ガラス板の表面に例えばレーザ加工によって所定深さのスクライブ線を複数形成する。その後、大寸ガラス板の表面を一対の突起部を有するアンビル（押さえ治具）でスクライブ線の１つを跨ぐように押さえた状態で裏面側からプッシャで押圧することで、大寸ガラスがスクライブ線に沿って割断される。 Conventionally, as shown in Patent Document 1, for example, when obtaining a glass piece of a predetermined size from a large glass plate, first, a plurality of scribe lines having a predetermined depth are formed on the surface of the large glass plate by, for example, laser processing. Form. After that, the large glass is scribed by pressing the surface of the large glass plate with a pusher from the back side while holding the surface of one of the scribe lines with an anvil (pressing jig) having a pair of protrusions. Cleaved along the line.
この割断によって得られる製品としてのガラス小片の表面には、その中央の大部分において一定の品質を保証できる有効エリアが設定されている。このため、割断によりガラス小片を得る際には、アンビルの一対の突起部でガラス小片の有効エリア外である端部付近のエリア（非有効エリア）を押さえるようにしている。つまり、割断しようとしているスクライブ線の両隣のスクライブ線の内側近傍の非有効エリアをアンビルの一対の突起部にて押さえるようにしており、アンビルの一対の突起部の間隔が製品部となるガラス小片２つ分の幅とほぼ等しくなっている。 On the surface of the glass piece as a product obtained by this cleaving, an effective area capable of assuring a certain quality is set in most of the center. For this reason, when a glass piece is obtained by cleaving, an area near the end (ineffective area) outside the effective area of the glass piece is pressed by a pair of protrusions of the anvil. In other words, the ineffective area near the inside of the scribe line adjacent to both sides of the scribe line to be cleaved is pressed by the pair of protrusions of the anvil, and a small glass piece in which the interval between the pair of protrusions of the anvil becomes the product section It is almost equal to the width of two.
ところで、大寸ガラス板の端部の割断片（所謂、耳部）は品質保証の点から廃棄されることになるが、上記のようにスクライブ線の近傍の非有効エリアをアンビルの一対の突起部で押さえる必要があることから、製品となるガラス小片に対して耳部を小さくすることができなかった。このため、大きいサイズのガラス小片を得たい場合に、廃棄する耳部も大きくなり歩留まりが悪化してしまう問題があった。 By the way, the split pieces (so-called ears) at the end of the large glass plate are discarded from the viewpoint of quality assurance. As described above, the ineffective area near the scribe line is treated as a pair of protrusions on the anvil. Since it was necessary to hold down by the part, the ear part could not be made small with respect to the glass piece as a product. Therefore, when it is desired to obtain a large glass piece, there is a problem in that the ear portion to be discarded becomes large and the yield deteriorates.
本発明は、上記課題を解決するためになされたものであって、その目的は、歩留まりを向上させることが可能な割断装置及び板状物品の製造方法を提供することにある。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cleaving apparatus and a method for manufacturing a plate-like article that can improve the yield.
上記課題を解決する割断装置は、互いに平行な複数の直線状のスクライブ線が形成された板材の表面を押さえ治具の一対の突起部にて前記スクライブ線の１つを跨いで押さえつつ、前記板材を裏面側からプッシャにて押圧して該板材を前記スクライブ線に沿って割断する割断装置であって、前記押さえ治具は、前記一対の突起部をそれぞれ有する第１アンビル部及び第２アンビル部を備え、前記第１アンビル部の一対の突起部の間隔が、前記第２アンビル部の一対の突起部の間隔よりも狭く構成されている。 The cleaving apparatus that solves the above-mentioned problem is the above-mentioned, while pressing the surface of a plate material on which a plurality of linear scribe lines parallel to each other are formed across a pair of protrusions of a pressing jig across one of the scribe lines. A cleaving device that crushes a plate material with a pusher from the back surface side and cleaves the plate material along the scribe line, wherein the pressing jig includes a first anvil portion and a second anvil each having the pair of protrusions. A gap between the pair of protrusions of the first anvil part is narrower than a distance between the pair of protrusions of the second anvil part.
この構成によれば、第１アンビル部の一対の突起部の間隔は、第２アンビル部の一対の突起部の間隔よりも狭く構成されているため、割断する板材の端部（耳部）の切り離しに第１アンビル部を用い、板材の耳部以外の製品部の切り離しに第２アンビル部を用いることで、廃棄される耳部の幅を製品部の幅よりも狭く設定しても、第１アンビル部の突起部でスクライブ線近傍の非有効エリアを押さえつつ耳部を切り離すことが可能となる。これにより、歩留まりの向上に寄与することができる。 According to this configuration, the distance between the pair of protrusions of the first anvil part is narrower than the distance between the pair of protrusions of the second anvil part. Even if the width of the discarded ear part is set narrower than the width of the product part by using the first anvil part for separation and the second anvil part for separating the product part other than the ear part of the plate material, It becomes possible to detach the ear while pressing the ineffective area near the scribe line with the protrusion of one anvil part. Thereby, it can contribute to the improvement of a yield.
上記割断装置において、前記第１アンビル部と前記第２アンビル部とは、相対的に移動不能に構成され、前記第１及び第２アンビル部のいずれか一方の各突起部が前記板材の表面に当接する状態で、他方の各突起部が前記板材の表面に対して板厚方向に離間することが好ましい。 In the cleaving apparatus, the first anvil portion and the second anvil portion are configured to be relatively immovable, and any one of the protrusions of the first and second anvil portions is formed on the surface of the plate member. In the abutting state, it is preferable that the other protrusions are separated from each other in the thickness direction with respect to the surface of the plate material.
この構成によれば、第１及び第２アンビル部のいずれか一方を用いた割断時に、他方のアンビル部の各突起部が板材の表面に触れないように構成でき、それにより、板材表面に微細な傷が入ることを抑制することができる。 According to this configuration, when cleaving using either one of the first and second anvil parts, each projection part of the other anvil part can be configured not to touch the surface of the plate material. Can be prevented from entering.
上記割断装置において、前記各アンビル部は、前記一対の突起部の対向方向と直交する方向に延びる長尺状をなし、前記第１アンビル部と前記第２アンビル部とは、それらの長手方向と直交する幅方向に並ぶように構成されていることが好ましい。 In the cleaving apparatus, each of the anvil portions has a long shape extending in a direction orthogonal to the opposing direction of the pair of protrusions, and the first anvil portion and the second anvil portion are in the longitudinal direction thereof. It is preferable to be arranged in the orthogonal width direction.
この構成によれば、各アンビル部が長手方向と直交する幅方向に並設されるため、第１及び第２アンビル部を有する押さえ治具の長手方向の小型化が可能となり、ひいては割断装置の小型化に寄与できる。 According to this structure, since each anvil part is arranged in parallel by the width direction orthogonal to a longitudinal direction, size reduction of the longitudinal direction of the holding jig which has the 1st and 2nd anvil part is attained, and by extension, the cleaving device of Contributes to downsizing.
上記課題を解決する板状物品の製造方法は、上記の割断装置を用いた板状物品の製造方法であって、前記第１アンビル部の各突起部と前記プッシャとによる挟圧にて前記各スクライブ線のうちの端に位置する端部スクライブ線に沿って前記板材を割断することで、前記板材からその端部の耳部を切り離す耳部切離工程と、前記第２アンビル部の各突起部と前記プッシャとによる挟圧にて前記各スクライブ線のうちの前記端部スクライブ線以外の中間スクライブ線に沿って前記板材を割断することで、前記板材から製品部を切り離す製品部切離工程とを備える。 A method for manufacturing a plate-shaped article that solves the above-described problem is a method for manufacturing a plate-shaped article using the above-described cleaving device. Ear part separating step of cutting off the ear part of the end part from the plate material by cleaving the plate material along the end part scribe line located at the end of the scribe line, and each projection of the second anvil part A product part separation step of separating the product part from the plate material by cleaving the plate material along an intermediate scribe line other than the end scribe line of the scribe lines by clamping pressure between the part and the pusher With.
この方法によれば、板材の耳部の切り離しに第１アンビル部が用いられ、板材の耳部以外の製品部の切り離しに、一対の突起部の間隔が第１アンビル部よりも広い第２アンビル部が用いられる。これにより、廃棄される耳部の幅を製品部の幅よりも狭く設定しても、第１アンビル部の一対の突起部でスクライブ線近傍の非有効エリアを押さえつつ耳部を切り離すことが可能となる。これにより、歩留まりの向上に寄与することができる。 According to this method, the first anvil portion is used for separating the ear portion of the plate material, and the second anvil having a wider interval between the pair of protrusions than the first anvil portion for separating the product portion other than the ear portion of the plate material. Part is used. As a result, even if the width of the ear part to be discarded is set narrower than the width of the product part, it is possible to separate the ear part while pressing the ineffective area near the scribe line with the pair of protrusions of the first anvil part. It becomes. Thereby, it can contribute to the improvement of a yield.
上記板状物品の製造方法において、前記耳部切離工程において、前記プッシャの押圧位置を前記端部スクライブ線よりも反耳部側にずらすことが好ましい。
この方法によれば、端部スクライブ線から第１アンビル部の各突起部までの距離の相違に応じて、プッシャの押圧位置を端部スクライブ線よりも反耳部側にずらすことで、端部スクライブ線から裏面まで延びる割断線の終点を該端部スクライブ線の真下に近づけることが可能となる。それにより、割断面の形状がいびつになることを抑制することが可能となる。
In the manufacturing method of the said plate-shaped article, it is preferable that the pressing position of the pusher is shifted to the side opposite to the ear portion from the end scribe line in the ear portion separation step.
According to this method, in accordance with the difference in the distance from the end scribe line to each projection of the first anvil part, the pusher pressing position is shifted to the side opposite to the end scribe line so that the end portion It is possible to bring the end point of the breaking line extending from the scribe line to the back surface close to the end scribe line. Thereby, it becomes possible to suppress the shape of the split section from becoming distorted.
本発明の割断装置及び板状物品の製造方法によれば、歩留まりを向上させることが可能となる。 According to the cleaving device and the plate-shaped article manufacturing method of the present invention, it is possible to improve the yield.

以下、割断装置１０を用いてガラス板１１を第１スクライブ線１４ａに沿って割断する態様を図１、図４及び図５に従って詳述する。なお、図１及び図４では左右方向に並ぶ各第１スクライブ線１４ａのうち、両端の線を端部スクライブ線１４ｃ，１４ｄとし、それら端部スクライブ線１４ｃ間に形成された各線を中間スクライブ線１４ｅとしている。
[Details of cleaving process]
Hereinafter, the aspect which cleaves the glass plate 11 along the 1st scribe line 14a using the cleaving apparatus 10 is explained in full detail according to FIG.1, FIG4 and FIG.5. In FIG. 1 and FIG. 4, among the first scribe lines 14a arranged in the left-right direction, both end lines are end scribe lines 14c and 14d, and each line formed between the end scribe lines 14c is an intermediate scribe line. 14e.
まず、ガラス板１１を一方の端部スクライブ線１４ｃに沿って割断することで、該端部スクライブ線１４ｃからガラス板１１の端部までの耳部１５を切り離す耳部切離工程を行う。 First, the ear | edge part cutting process which cuts off the ear | edge part 15 from this edge part scribe line 14c to the edge part of the glass plate 11 is performed by cleaving the glass plate 11 along one edge part scribe line 14c.
図１に示すように、第１スクライブ線１４ａが第１アンビル部材２１の各突起部２３ａ，２３ｂと平行となるように載置台に水平配置されたガラス板１１を、前記押出装置により第１スクライブ線１４ａと直交する板面方向（図１において左方向）に移動させる。そして、ガラス板１１の移動方向前方側の端部１１ｃを位置決め部３１に当接させることで、ガラス板１１を第１スクライブ線１４ａと直交する板面方向に位置決めする。このとき、ガラス板１１の裏面１１ｂ側に配置されているプッシャ１３は、ガラス板１１の裏面１１ｂから離間する退避位置にある。また、このとき、各アンビル部材２１，２２を有する押さえ治具１２はガラス板１１の上方に配置され、各アンビル部材２１，２２がガラス板１１の表面１１ａから離間されている。 As shown in FIG. 1, the glass plate 11 horizontally arranged on the mounting table so that the first scribe line 14a is parallel to the projections 23a and 23b of the first anvil member 21 is squeezed by the extrusion device. It is moved in the plate surface direction (left direction in FIG. 1) orthogonal to the line 14a. And the glass plate 11 is positioned in the plate | board surface direction orthogonal to the 1st scribe line 14a by making the edge part 11c of the moving direction front side of the glass plate 11 contact | abut to the positioning part 31. FIG. At this time, the pusher 13 disposed on the back surface 11 b side of the glass plate 11 is in a retracted position away from the back surface 11 b of the glass plate 11. At this time, the holding jig 12 having the anvil members 21 and 22 is disposed above the glass plate 11, and the anvil members 21 and 22 are separated from the surface 11 a of the glass plate 11.
次に、図４（ａ）に示すように、押さえ治具１２を下降させて、その第１アンビル部材２１の一対の突起部２３ａ，２３ｂをガラス板１１の表面１１ａに対して端部スクライブ線１４ｃを跨ぐように当接させる。このとき、第１アンビル部材２１の一方の突起部２３ａは、耳部１５表面（本実施形態ではガラス板１１の端部１１ｃの表面）に当接する。また、他方の突起部２３ｂは、端部スクライブ線１４ｃの直近の中間スクライブ線１４ｅに沿った非有効エリアＡ２であって該中間スクライブ線１４ｅよりも端部スクライブ線１４ｃ側の非有効エリアＡ２（図２参照）と当接する。つまり、第１アンビル部材２１の各突起部２３ａ，２３ｂの間隔Ｄ１は、耳部１５の幅と短冊状の割断片Ｃの１つ分の幅の合計幅よりも若干狭くなるように設定されている。これにより、他方の突起部２３ｂがガラス板１１の製品部１６の有効エリアＡ１（図２参照）に当接しないようにしつつ、各突起部２３ａ，２３ｂにてガラス板１１の表面１１ａを端部スクライブ線１４ｃのみを跨いで支持することが可能となっている。 Next, as shown in FIG. 4A, the holding jig 12 is lowered, and the pair of protrusions 23 a and 23 b of the first anvil member 21 are end scribe lines with respect to the surface 11 a of the glass plate 11. It is made to contact so that 14c may be straddled. At this time, one protrusion 23a of the first anvil member 21 contacts the surface of the ear 15 (in this embodiment, the surface of the end 11c of the glass plate 11). The other protrusion 23b is a non-effective area A2 along the intermediate scribe line 14e closest to the end scribe line 14c, and the non-effective area A2 (on the end scribe line 14c side of the intermediate scribe line 14e). (See FIG. 2). That is, the distance D1 between the protrusions 23a and 23b of the first anvil member 21 is set to be slightly smaller than the total width of the width of the ear portion 15 and the width of one strip-shaped split piece C. Yes. Thereby, while preventing the other protrusion 23b from coming into contact with the effective area A1 (see FIG. 2) of the product portion 16 of the glass plate 11, the surface 11a of the glass plate 11 is end-ended by the protrusions 23a and 23b. It is possible to support across the scribe line 14c.
また、このとき、第１アンビル部材２１と隣接する第２アンビル部材２２は、ガラス板１１の上方に位置しており、第２アンビル部材２２の各突起部２５ａ，２５ｂは、ガラス板１１の表面１１ａから離間されている。 Moreover, the 2nd anvil member 22 adjacent to the 1st anvil member 21 is located above the glass plate 11 at this time, and each projection part 25a, 25b of the 2nd anvil member 22 is the surface of the glass plate 11. 11a.
そして、上記のように第１アンビル部材２１の各突起部２３ａ，２３ｂがガラス板１１の表面１１ａと当接する状態で、プッシャ１３を上昇させて、ガラス板１１の裏面１１ｂの所定箇所（以下、押圧位置Ｐ）をプッシャ１３先端の当接部１３ａで押圧する。これにより、ガラス板１１が端部スクライブ線１４ｃに沿って割断され、耳部１５がガラス板１１から切り離される。なお、切り離された耳部１５は、吸気孔２８からの吸引によって第１アンビル部材２１に保持されるとともに、第１アンビル部材２１を含む押さえ治具１２の移動によって搬送される。 And in the state which each protrusion part 23a, 23b of the 1st anvil member 21 contact | abutted with the surface 11a of the glass plate 11 as mentioned above, the pusher 13 is raised and the predetermined location (henceforth, below) of the back surface 11b of the glass plate 11 is called. The pressing position P) is pressed by the contact portion 13a at the tip of the pusher 13. Thereby, the glass plate 11 is cleaved along the end scribe line 14 c, and the ear portion 15 is separated from the glass plate 11. The separated ear portion 15 is held by the first anvil member 21 by suction from the intake hole 28 and is conveyed by the movement of the holding jig 12 including the first anvil member 21.
ここで、プッシャ１３の押圧位置Ｐを端部スクライブ線１４ｃの真下位置に設定した場合を考える。この場合、端部スクライブ線１４ｃから一方の突起部２３ａまでの距離が端部スクライブ線１４ｃから他方の突起部２３ｂまでの距離よりも短いことで生じる応力のアンバランスによって、図４（ｂ）中の２点鎖線で示すように、端部スクライブ線１４ｃを起点としてガラス板１１の裏面１１ｂまで延びる割断線Ｌ１の終点Ｅ１が端部スクライブ線１４ｃよりもガラス板１１の端部１１ｃ側にずれる。それにより、割断面の形状がいびつなものとなってしまう。 Here, consider a case where the pressing position P of the pusher 13 is set to a position directly below the end scribe line 14c. In this case, in FIG. 4B, due to the unbalance of stress generated when the distance from the end scribe line 14c to the one protrusion 23a is shorter than the distance from the end scribe line 14c to the other protrusion 23b. As shown by the two-dot chain line, the end point E1 of the breaking line L1 extending from the end scribe line 14c to the back surface 11b of the glass plate 11 is shifted to the end 11c side of the glass plate 11 from the end scribe line 14c. As a result, the shape of the broken section becomes distorted.
その割断線Ｌ１のずれを抑制すべく、本実施形態では、プッシャ１３の押圧位置Ｐを、端部スクライブ線１４ｃに対して他方の突起部２３ｂ側にずらし幅Ｗだけずらしている。これにより、プッシャ１３の押圧によって端部スクライブ線１４ｃから裏面１１ｂまで延びる割断線Ｌ２の終点Ｅ２が該端部スクライブ線１４ｃの真下に近づくようになっている。 In this embodiment, the pressing position P of the pusher 13 is shifted toward the other projection 23b side by the width W in order to suppress the shift of the breaking line L1. As a result, the end point E2 of the breaking line L2 extending from the end scribe line 14c to the back surface 11b by pressing of the pusher 13 comes close to the end scribe line 14c.
次に、ガラス板１１を中間スクライブ線１４ｅに沿って割断することで、製品部１６を含む短冊状の割断片Ｃを切り離す製品部切離工程を行う。
上記の耳部切離工程でガラス板１１の端部１１ｃの耳部１５を切り離した後、押さえ治具１２を上方に移動し、プッシャ１３を退避位置まで下降させる。その後、図５（ａ）に示すように、耳部１５が切り離されたガラス板１１を前記押出装置にて移動させて、ガラス板１１の移動方向前方側の端部１１ｄ（上記耳部割断工程によって新たにできた端部）を位置決め部３１に当接させる。これにより、ガラス板１１が第１スクライブ線１４ａと直交する板面方向に位置決めされる。このとき、位置決め部３１は、プッシャ１３との間隔が割断片Ｃの幅（各第１スクライブ線１４ａの間隔）に応じた間隔となるように、上記耳部割断工程での配置位置からプッシャ１３に対して離間する方向に移動されている。
Next, the product part cutting process which cuts the strip-shaped split piece C containing the product part 16 is performed by cleaving the glass plate 11 along the intermediate scribe line 14e.
After cutting off the ear portion 15 of the end portion 11c of the glass plate 11 in the above-described ear portion separation step, the holding jig 12 is moved upward, and the pusher 13 is lowered to the retracted position. Then, as shown to Fig.5 (a), the glass plate 11 from which the ear | edge part 15 was cut | disconnected is moved with the said extrusion apparatus, and the edge part 11d of the moving direction front side of the glass plate 11 (the said ear | edge part cutting process) The end portion newly formed by the step is brought into contact with the positioning portion 31. Thereby, the glass plate 11 is positioned in the plate | board surface direction orthogonal to the 1st scribe line 14a. At this time, the positioning unit 31 pushes the pusher 13 from the arrangement position in the ear cleaving step so that the interval with the pusher 13 becomes an interval according to the width of the split piece C (interval of each first scribe line 14a). Are moved away from each other.
その後、押さえ治具１２を下降させて、その第２アンビル部材２２の一対の突起部２５ａ，２５ｂをガラス板１１の表面１１ａに当接させる。このとき、第２アンビル部材２２の各突起部２５ａ，２５ｂは、割断しようとしている中間スクライブ線１４ｆ（ガラス板１１の端部１１ｄの直近の中間スクライブ線）に対する対称位置に当接される。詳述すると、第２アンビル部材２２の一方の突起部２５ａは、ガラス板１１の端部１１ｄ近傍の非有効エリアＡ２（上記耳部切離工程で割断した端部スクライブ線１４ｃに沿った非有効エリアＡ２）と当接する。また、他方の突起部２５ｂは、割断しようとしている中間スクライブ線１４ｆの隣の中間スクライブ線１４ｇに沿った非有効エリアＡ２であって該中間スクライブ線１４ｇよりも中間スクライブ線１４ｆ側の非有効エリアＡ２と当接する。つまり、第２アンビル部材２２の各突起部２５ａ，２５ｂの間隔Ｄ２は、短冊状の割断片Ｃの２つ分の幅よりも若干狭くなるように設定されている。これにより、第２アンビル部材２２の各突起部２５ａ，２５ｂがガラス板１１の製品部１６の有効エリアＡ１に当接しないようにしつつ、各突起部２５ａ，２５ｂにて割断しようとしている中間スクライブ線１４ｆのみを跨いでガラス板１１の表面１１ａを支持することが可能となっている。 Thereafter, the holding jig 12 is lowered to bring the pair of protrusions 25 a and 25 b of the second anvil member 22 into contact with the surface 11 a of the glass plate 11. At this time, each protrusion 25a, 25b of the 2nd anvil member 22 is contact | abutted to the symmetrical position with respect to the intermediate | middle scribe line 14f (intermediate scribe line nearest to the edge part 11d of the glass plate 11) which is going to cut. More specifically, one protrusion 25a of the second anvil member 22 is ineffective area A2 in the vicinity of the edge 11d of the glass plate 11 (ineffective along the edge scribe line 14c cleaved in the ear cutting process). Abuts with area A2). The other protrusion 25b is an ineffective area A2 along the intermediate scribe line 14g adjacent to the intermediate scribe line 14f to be cleaved, and is an ineffective area on the intermediate scribe line 14f side of the intermediate scribe line 14g. Abuts with A2. That is, the interval D2 between the protrusions 25a and 25b of the second anvil member 22 is set to be slightly narrower than the width of the two strip-shaped split pieces C. As a result, the intermediate scribe line that is about to be cleaved at each of the protrusions 25a and 25b while preventing the protrusions 25a and 25b of the second anvil member 22 from coming into contact with the effective area A1 of the product portion 16 of the glass plate 11. It is possible to support the surface 11a of the glass plate 11 across only 14f.
また、このとき、第２アンビル部材２２と隣接する第１アンビル部材２１は、ガラス板１１の側方に位置しており、第２アンビル部材２２の各突起部２５ａ，２５ｂがガラス板１１の表面１１ａと接触しないようになっている。 Moreover, the 1st anvil member 21 adjacent to the 2nd anvil member 22 is located in the side of the glass plate 11 at this time, and each projection part 25a, 25b of the 2nd anvil member 22 is the surface of the glass plate 11. It does not come into contact with 11a.
そして、上記のように第２アンビル部材２２の各突起部２５ａ，２５ｂがガラス板１１の表面１１ａと当接する状態で、プッシャ１３を上昇させて、該プッシャ１３先端の当接部１３ａでガラス板１１の裏面１１ｂにおける中間スクライブ線１４ｆの真下位置を押圧する。これにより、ガラス板１１が中間スクライブ線１４ｆに沿って割断され、短冊状の割断片Ｃがガラス板１１から切り離される。なお、切り離された割断片Ｃは、吸気孔２８からの吸引によって第２アンビル部材２２に保持されるとともに、第２アンビル部材２２を含む押さえ治具１２の移動によって搬送される。 Then, as described above, the pusher 13 is raised in a state where the projections 25a and 25b of the second anvil member 22 are in contact with the surface 11a of the glass plate 11, and the glass plate is moved by the contact portion 13a at the tip of the pusher 13. 11 is pressed directly below the intermediate scribe line 14f on the back surface 11b. Thereby, the glass plate 11 is cut along the intermediate scribe line 14 f, and the strip-shaped split piece C is cut off from the glass plate 11. The separated piece C is held by the second anvil member 22 by suction from the intake hole 28 and is conveyed by the movement of the holding jig 12 including the second anvil member 22.
上記の中間スクライブ線１４ｅの割断工程（製品部切離工程）は、中間スクライブ線１４ｅの本数だけ繰り返し行われる。
その後、図５（ｂ）に示すように、第１アンビル部材２１を用いて最後に残った端部スクライブ線１４ｄに沿ってガラス板１１を割断する。この割断は、前述の第１アンビル部材２１を用いた耳部切離工程と略同様の態様であるため、詳細な説明を省略する。この割断によって、短冊状の割断片Ｃと耳部１５とが切り離される。これにて、各第１スクライブ線１４ａに沿ったガラス板１１の割断が完了し、短冊状の各割断片Ｃが得られる。
The cleaving process (product part separating process) of the intermediate scribe line 14e is repeated for the number of intermediate scribe lines 14e.
Then, as shown in FIG.5 (b), the glass plate 11 is cut along the edge part scribe line 14d finally left using the 1st anvil member 21. FIG. Since this cleaving is a mode substantially the same as the above-described ear separation step using the first anvil member 21, detailed description thereof is omitted. By this cleaving, the strip-shaped split piece C and the ear portion 15 are separated. Thereby, the cleaving of the glass plate 11 along each first scribe line 14a is completed, and each strip-shaped fragment C is obtained.
次に、各割断片Ｃを各第２スクライブ線１４ｂに沿って割断し、複数の矩形状の製品部１６が形成される。この割断は、割断片Ｃの長手方向両端部を含む耳部１５ａの幅と製品部１６の幅（第２スクライブ線１４ｂの間隔）に応じて一対の突起部の間隔が設定された第１及び第２アンビル部材を用いて、上記した各第１スクライブ線１４ａに沿った割断と同様に行われる。なお、製品部１６の形状が正方形の場合には、上記の第１及び第２アンビル部材２１，２２を用いて各第２スクライブ線１４ｂに沿った割断を行うことが可能である。 Next, each split piece C is cut along each second scribe line 14b, and a plurality of rectangular product portions 16 are formed. In this cleaving, the first and second protrusions are spaced in accordance with the width of the ear portion 15a including both longitudinal ends of the split piece C and the width of the product portion 16 (interval between the second scribe lines 14b). The second anvil member is used in the same manner as the cleaving along the first scribe lines 14a. In addition, when the shape of the product part 16 is a square, it is possible to cleave along each 2nd scribe line 14b using said 1st and 2nd anvil members 21 and 22. FIG.
次に、本実施形態の作用について説明する。
ガラス板１１において、廃棄される耳部１５の幅が製品部１６の幅（割断片Ｃの幅）よりも狭く設定され、それに応じて第１アンビル部材２１の各突起部２３ａ，２３ｂの間隔Ｄ１が、第２アンビル部材２２の各突起部２５ａ，２５ｂの間隔Ｄ２よりも狭く構成されている。そして、第１アンビル部材２１をガラス板１１の耳部１５の切り離しに用いることで、その第１アンビル部材２１の突起部２３ｂがガラス板１１の製品部１６の有効エリアＡ１に当接しないようにしつつも、端部スクライブ線１４ｃに沿ったガラス板１１の割断が可能となっている。また、第２アンビル部材２２を製品となる割断片Ｃ（詳しくは製品部１６を含む割断片Ｃ）の切り離しに用いることで、その第２アンビル部材２２の各突起部２５ａ，２５ｂがガラス板１１の製品部１６の有効エリアＡ１に当接しないようにしつつも、中間スクライブ線１４ｅに沿ったガラス板１１の割断が可能となっている。
Next, the operation of this embodiment will be described.
In the glass plate 11, the width of the discarded ear portion 15 is set to be narrower than the width of the product portion 16 (the width of the split piece C), and the distance D <b> 1 between the projections 23 a and 23 b of the first anvil member 21 accordingly. However, it is comprised narrower than the space | interval D2 of each projection part 25a, 25b of the 2nd anvil member 22. FIG. And by using the 1st anvil member 21 for cutting off the ear | edge part 15 of the glass plate 11, the projection part 23b of the 1st anvil member 21 does not contact | abut to the effective area A1 of the product part 16 of the glass plate 11. FIG. However, it is possible to cleave the glass plate 11 along the end scribe line 14c. Further, by using the second anvil member 22 for cutting off the split piece C (specifically, the split piece C including the product portion 16) as a product, the projections 25a and 25b of the second anvil member 22 are formed on the glass plate 11. It is possible to cleave the glass plate 11 along the intermediate scribe line 14e, while preventing it from coming into contact with the effective area A1 of the product part 16.
次に、本実施形態の特徴的な効果を記載する。
（１）割断装置１０の押さえ治具１２は、一対の突起部２３ａ，２３ｂを有する第１アンビル部材２１と、一対の突起部２５ａ，２５ｂを有する第２アンビル部材２２とを備え、第１アンビル部材２１の各突起部２３ａ，２３ｂの間隔Ｄ１は、第２アンビル部材２２の各突起部２５ａ，２５ｂの間隔Ｄ２よりも狭く構成される。そして、ガラス板１１の端部（耳部１５）の切り離しに第１アンビル部材２１を用い、製品となる割断片Ｃ（詳しくは製品部１６を含む割断片Ｃ）の切り離しに第２アンビル部材２２を用いる。これにより、廃棄される耳部１５の幅を製品部１６の幅（割断片Ｃの幅）よりも狭く設定しても、第１アンビル部材２１の一方の突起部２３ｂで中間スクライブ線１４ｅ近傍の非有効エリアＡ２を押さえつつ耳部１５を切り離すことが可能となる。そして、廃棄される耳部１５を小さく設定できることから歩留まりの向上に寄与することができる。
Next, characteristic effects of the present embodiment will be described.
(1) The holding jig 12 of the cleaving device 10 includes a first anvil member 21 having a pair of protrusions 23a and 23b and a second anvil member 22 having a pair of protrusions 25a and 25b. The distance D1 between the protrusions 23a and 23b of the member 21 is configured to be narrower than the distance D2 between the protrusions 25a and 25b of the second anvil member 22. Then, the first anvil member 21 is used for separating the end portion (ear portion 15) of the glass plate 11, and the second anvil member 22 is used for separating the split piece C (specifically, the split piece C including the product portion 16) as a product. Is used. Thereby, even if the width of the discarded ear portion 15 is set to be narrower than the width of the product portion 16 (the width of the split piece C), the one projecting portion 23b of the first anvil member 21 near the intermediate scribe line 14e. The ear portion 15 can be separated while pressing the ineffective area A2. And since the ear | edge part 15 discarded can be set small, it can contribute to the improvement of a yield.
（２）押さえ治具１２を構成する第１及び第２アンビル部材２１，２２は相対的に移動不能に構成される。そして、第１アンビル部材２１の各突起部２３ａ，２３ｂがガラス板１１の表面１１ａに当接する状態で、第２アンビル部材２２の各突起部２５ａ，２５ｂがガラス板１１の表面１１ａに対して板厚方向に離間するように構成される。このため、第１アンビル部材２１を用いた割断時に、第２アンビル部材２２の各突起部２５ａ，２５ｂがガラス板１１の表面１１ａに触れないように構成でき、それにより、ガラス板１１の表面１１ａに微細な傷が入ることを抑制することができる。 (2) The first and second anvil members 21 and 22 constituting the pressing jig 12 are relatively immovable. And each projection part 25a, 25b of the 2nd anvil member 22 is a plate with respect to the surface 11a of the glass plate 11 in the state which each projection part 23a, 23b of the 1st anvil member 21 contact | abuts to the surface 11a of the glass plate 11. It is configured to be separated in the thickness direction. For this reason, at the time of cleaving using the first anvil member 21, the projections 25 a and 25 b of the second anvil member 22 can be configured not to touch the surface 11 a of the glass plate 11, thereby the surface 11 a of the glass plate 11. It is possible to prevent fine scratches from entering.
（３）各アンビル部材２１，２２は、一対の突起部２３ａ，２３ｂ，２５ａ，２５ｂの対向方向と直交する方向に延びる長尺状をなし、第１アンビル部材２１と第２アンビル部材２２とは、それらの長手方向と直交する幅方向に並ぶように構成される。これにより、第１及び第２アンビル部材２１，２２を有する押さえ治具１２の長手方向の小型化が可能となり、ひいては割断装置１０の小型化に寄与できる。 (3) Each anvil member 21, 22 has an elongated shape extending in a direction orthogonal to the opposing direction of the pair of protrusions 23 a, 23 b, 25 a, 25 b, and the first anvil member 21 and the second anvil member 22 are , And are arranged in the width direction orthogonal to the longitudinal direction thereof. As a result, the holding jig 12 having the first and second anvil members 21 and 22 can be downsized in the longitudinal direction, thereby contributing to downsizing of the cleaving device 10.
（４）耳部切離工程において、プッシャ１３の押圧位置Ｐを端部スクライブ線１４ｃ，１４ｄよりも反耳部側（中間スクライブ線１４ｅ側）にずらしている。この方法によれば、第１アンビル部材２１とプッシャ１３とによる挟圧時に端部スクライブ線１４ｃ，１４ｄからガラス板１１の裏面１１ｂまで延びる割断線Ｌ２の終点Ｅ１を、該端部スクライブ線１４ｃ，１４ｄの真下に近づけることが可能となる。それにより、割断面の形状がいびつになることを抑制することが可能となる。 (4) In the ear part separation step, the pressing position P of the pusher 13 is shifted to the opposite ear part side (intermediate scribe line 14e side) from the end scribe lines 14c and 14d. According to this method, when the first anvil member 21 and the pusher 13 are clamped, the end point E1 of the breaking line L2 extending from the end scribe lines 14c, 14d to the back surface 11b of the glass plate 11 is set to the end scribe line 14c, It becomes possible to be close to 14d. Thereby, it becomes possible to suppress the shape of the split section from becoming distorted.
なお、上記実施形態は、以下のように変更してもよい。
・上記実施形態では、各アンビル部材２１，２２は、それらの幅方向（短手方向）に並ぶように配置されたが、これ以外に例えば、長手方向に並ぶように配置してもよい。
In addition, you may change the said embodiment as follows.
In the above-described embodiment, the anvil members 21 and 22 are arranged so as to be aligned in the width direction (short direction), but other than this, for example, they may be arranged in the longitudinal direction.
