Description

ガラス板の製造方法及びスクライブ装置Glass plate manufacturing method and scribing apparatus
　本発明は、ガラス板にスクライブ線を形成する工程を含むガラス板の製造方法、及び、スクライブ装置に関する。 The present invention relates to a glass plate manufacturing method including a step of forming a scribe line on a glass plate, and a scribe device.
　周知のように、ガラス板の製造工程では、製品サイズに切り出すためにガラス板を切断する場合が多い。ガラス板を切断するための手法の一例としては、ガラス板にスクライブ線を形成した後、スクライブ線を起点にガラス板を折割って切断する手法を挙げることができる。 As is well known, in the manufacturing process of a glass plate, the glass plate is often cut in order to cut it into a product size. As an example of a method for cutting the glass plate, a method of forming a scribe line on the glass plate and then breaking and cutting the glass plate with the scribe line as a starting point can be given.
　ここで、ガラス板にスクライブ線を形成する具体的な態様は、例えば、特許文献１に開示されている。また、同文献に開示された態様の他、図３に示すようなスクライブ装置１００を用いることによっても、ガラス板にスクライブ線を形成することが可能である。 Here, a specific mode of forming the scribe line on the glass plate is disclosed in Patent Document 1, for example. In addition to the mode disclosed in the same document, it is possible to form a scribe line on a glass plate by using a scribe device 100 as shown in FIG.
　図３に示すスクライブ装置１００は、相互に平行な二本のラック１０１と、両ラック１０１，１０１に沿ってそれぞれ転動する二つのピニオン１０２と、両ピニオン１０２，１０２に動力を付与する二基のサーボモーター１０３と、両ピニオン１０２，１０２の転動に伴って両ラック１０１，１０１と平行な方向Ｖに移動しつつ、ガラス板Ｇにスクライブ線Ｓを形成する本体１０４とを備えている。 The scribing apparatus 100 shown in FIG. 3 includes two racks 101 that are parallel to each other, two pinions 102 that roll along the racks 101 and 101, and two groups that apply power to both pinions 102 and 102, respectively. Servo motor 103 and a main body 104 that forms a scribe line S on a glass plate G while moving in a direction V parallel to both racks 101 and 101 as the both pinions 102 and 102 roll.
　本体１０４は、一対のホイールカッター１０４ａ，１０４ａを備えており、本体１０４の移動に伴って各ホイールカッター１０４ａがガラス板Ｇ上を走行し、切断予定線Ｘに沿ってスクライブ線Ｓを形成する。なお、両ラック１０１，１０１の相互間には、これらのラック１０１と平行に延びた一対のガイド１０５，１０５が設置されており、本体１０４は、両ガイド１０５，１０５に案内されながら方向Ｖに移動していく。 The main body 104 includes a pair of wheel cutters 104a and 104a. As the main body 104 moves, each wheel cutter 104a travels on the glass plate G and forms a scribe line S along the planned cutting line X. A pair of guides 105, 105 extending in parallel with the racks 101 are installed between the racks 101, 101, and the main body 104 is guided in the direction V while being guided by the guides 105, 105. Move.
特開２００８－１５６１８０号公報JP 2008-156180 A
　ところで、上記のようなスクライブ装置を用いて、ガラス板にスクライブ線を形成する場合には、下記のような解決すべき問題があった。 Incidentally, when the scribe line is formed on the glass plate using the scribe device as described above, there are the following problems to be solved.
　すなわち、図３に示したスクライブ装置１００は、一基のみでなく、二基のサーボモーター１０３を備えている。これは、近年におけるガラス板Ｇの大型化に伴い、スクライブ装置１００も大型化していることに対応したものである。しかしながら、このように動力源として複数のサーボモーター１０３を備えている場合には、サーボモーター１０３の動作（始動時期や回転数等）がずれることによって不具合が生じる。 That is, the scribing apparatus 100 shown in FIG. 3 includes not only one but also two servo motors 103. This corresponds to the fact that the scribing apparatus 100 is also enlarged with the increase in the size of the glass plate G in recent years. However, when a plurality of servo motors 103 are provided as a power source in this way, a malfunction occurs due to a shift in the operation (starting time, rotation speed, etc.) of the servo motor 103.
　例えば、一方のサーボモーター１０３の回転数が低下した場合、図４に示すように、両ピニオン１０２，１０２の一方が他方に対して先行し、これに伴って本体１０４が不当に傾いてしまう。このような事態が生じると、切断予定線Ｘ（後で折割りにより切断される箇所となる線）に沿って形成されるべきスクライブ線Ｓが、切断予定線Ｘから逸れてしまう。その結果、ガラス板Ｇを所望のとおりに折割って切断することが不可能となる難点があった。あるいは、サーボモーター１０３が過負荷となり、本体１０４の移動が停止してしまう場合もあった。 For example, when the rotational speed of one servo motor 103 decreases, as shown in FIG. 4, one of both pinions 102 and 102 precedes the other, and accordingly, the main body 104 tilts unjustly. When such a situation occurs, the scribe line S to be formed along the planned cutting line X (the line that will be cut later by splitting) deviates from the planned cutting line X. As a result, there is a difficulty that it is impossible to break and cut the glass plate G as desired. Alternatively, the servo motor 103 may be overloaded and the movement of the main body 104 may stop.
　なお、このような問題は、複数のサーボモーターを動力源として備えたスクライブ装置のみでなく、複数の動力源の動作を相互に同期させるコントローラを更に備えたスクライブ装置により、ガラス板にスクライブ線を形成する場合にも発生し得る。例えば、図３に示すスクライブ装置１００であれば、一方のサーボモーター１０３とピニオン１０２との間にのみ滑りが発生すれば、複数のサーボモーター１０３について同期制御を行っていても本体１０４が傾いてしまう。 Such a problem is caused not only by a scribing device having a plurality of servo motors as a power source, but also by a scribing device further having a controller for synchronizing the operations of the plurality of power sources with each other. It can also occur when forming. For example, in the case of the scribing device 100 shown in FIG. 3, if a slip occurs only between one servo motor 103 and the pinion 102, the main body 104 tilts even if synchronous control is performed for the plurality of servo motors 103. End up.
　上記の事情に鑑みなされた本発明は、ガラス板を製造するに際し、複数の動力源を備えたスクライブ装置により、ガラス板にスクライブ線を形成する場合に、スクライブ線の形成不良を回避することを技術的な課題とする。 The present invention made in view of the above circumstances avoids the formation failure of the scribe line when the scribe line is formed on the glass plate by the scribe device having a plurality of power sources when the glass plate is manufactured. Technical issues.
　上記の課題を解決するために創案された本発明に係る方法は、相互に平行な複数の直線軌道と、複数の直線軌道に沿ってそれぞれ転動する複数の転動体と、複数の転動体に動力を付与する複数の動力源と、複数の転動体の転動に伴って複数の直線軌道と平行に移動しつつ、ガラス板にスクライブ線を形成する本体とを備えたスクライブ装置を用いて、ガラス板にスクライブ線を形成する工程を含むガラス板の製造方法であって、複数の転動体を動力伝達機構により機械的に連結したことに特徴付けられる。 The method according to the present invention, which was created to solve the above problems, includes a plurality of linear tracks that are parallel to each other, a plurality of rolling elements that respectively roll along a plurality of linear tracks, and a plurality of rolling elements. Using a scribing device comprising a plurality of power sources for applying power, and a main body that forms a scribe line on a glass plate while moving in parallel with a plurality of linear tracks as the plurality of rolling elements roll, A glass plate manufacturing method including a step of forming a scribe line on a glass plate, characterized in that a plurality of rolling elements are mechanically connected by a power transmission mechanism.
　この方法では、複数の直線軌道に沿ってそれぞれ転動する複数の転動体を動力伝達機構により機械的に連結している。そのため、これら複数の転動体に動力を付与する複数の動力源の動作にずれが発生した場合や、一部の動力源と転動体との間に滑りが発生した場合でも、複数のうちの一部の転動体が、他の転動体に対して先行するような事態の発生を回避できる。これにより、ガラス板にスクライブ線を形成する本体が、不当に傾くことを防止できる。その結果、スクライブ線の形成不良を回避することが可能となる。 In this method, a plurality of rolling elements that respectively roll along a plurality of linear tracks are mechanically connected by a power transmission mechanism. For this reason, even when a shift occurs in the operation of the plurality of power sources that apply power to the plurality of rolling elements, or when slipping occurs between some of the power sources and the rolling elements, Occurrence of a situation in which the rolling elements of the part precede the other rolling elements can be avoided. Thereby, it can prevent that the main body which forms a scribe line in a glass plate inclines unjustly. As a result, it is possible to avoid the formation failure of the scribe line.
　上記の方法では、スクライブ装置が複数の動力源の動作を相互に同期させるコントローラを更に備え、コントローラによって複数の動力源に対して同期制御を行うことが好ましい。 In the above method, it is preferable that the scribing device further includes a controller that synchronizes the operations of the plurality of power sources with each other, and the controller performs synchronous control on the plurality of power sources.
　このようにすれば、動力源の負荷を均一として、本体に掛かる荷重を低減できる。これにより、スクライブ線の形成の精度を向上させることもできる。 In this way, the load applied to the main body can be reduced by making the load of the power source uniform. Thereby, the precision of formation of a scribe line can also be improved.
　上記の方法では、直線軌道としてラックを用いると共に、転動体としてピニオンを用いることが好ましい。 In the above method, it is preferable to use a rack as the linear track and a pinion as the rolling element.
　このようにすれば、スクライブ装置において、ラック・アンド・ピニオン機構により本体を移動させ得ることになり、スクライブ装置の構造について簡易化を図ることが可能となる。これにより、スクライブ装置の保守・点検等に要するコストを抑制できる。 In this way, in the scribe device, the main body can be moved by the rack and pinion mechanism, and the structure of the scribe device can be simplified. Thereby, the cost required for maintenance and inspection of the scribe device can be suppressed.
　上記の方法では、複数の動力源の数と複数の転動体の数とを同数とすると共に、複数の動力源の各々に駆動軸を設け、各駆動軸に複数の転動体の各々を取り付け、動力伝達機構が、副軸を介して駆動軸の回転を互いに伝達するようにしてもよい。 In the above method, the number of the plurality of power sources and the number of the plurality of rolling elements are the same, and a drive shaft is provided for each of the plurality of power sources, and each of the plurality of rolling elements is attached to each drive shaft, The power transmission mechanism may transmit the rotation of the drive shaft to each other via the auxiliary shaft.
　このようにした場合には、複数の動力源に駆動軸をそれぞれ設け、それらの駆動軸の回転を動力伝達機構の副軸を介して互いに伝達することにより、複数の転動体が機械的に連結された状態となる。これにより、動作ずれや滑りが発生した場合であっても、その影響を好適に打ち消すことが可能である。 In this case, a plurality of rolling elements are mechanically connected by providing drive shafts to the plurality of power sources and transmitting the rotations of the drive shafts to each other via the auxiliary shaft of the power transmission mechanism. It will be in the state. As a result, even when a motion shift or slip occurs, it is possible to suitably cancel the influence.
　上記の方法では、動力伝達機構として、複数の転動体が取り付けられた単一の軸を用いると共に、軸を介して複数の動力源から複数の転動体に動力を付与してもよい。 In the above method, a single shaft with a plurality of rolling elements attached may be used as the power transmission mechanism, and power may be applied to the plurality of rolling elements from a plurality of power sources via the shaft.
　このようにした場合には、単一の軸のみで複数の転動体を機械的に連結できる。これにより、複数の転動体を相互に同期した状態で転動させる上で有利となる。その結果、動作ずれや滑りが発生した場合でも、複数のうちの一部の転動体が、他の転動体に対して先行するような事態の発生をより好適に回避することが可能である。 In this case, a plurality of rolling elements can be mechanically connected only by a single shaft. This is advantageous in rolling a plurality of rolling elements in a synchronized state. As a result, even when an operation shift or slip occurs, it is possible to more suitably avoid the occurrence of a situation in which some of the rolling elements precede the other rolling elements.
　上記の方法では、複数の直線軌道と平行に延びる対称軸を基準として、スクライブ装置を対称な構成とすると共に、スクライブ装置の重心を対称軸上に位置させることが好ましい。 In the above method, it is preferable that the scribing device is configured symmetrically with respect to a symmetry axis extending in parallel with the plurality of linear trajectories, and the center of gravity of the scribing device is positioned on the symmetry axis.
　このようにすれば、ガラス板にスクライブ線を形成する本体がより不当に傾き難くなるため、スクライブ線の形成不良を回避する上で更に有利となる。 In this way, the main body for forming the scribe line on the glass plate becomes more difficult to tilt unreasonably, which is further advantageous in avoiding the formation failure of the scribe line.
　また、上記の課題を解決するために創案された本発明に係る装置は、相互に平行な複数の直線軌道と、複数の直線軌道に沿ってそれぞれ転動する複数の転動体と、複数の転動体に動力を付与する複数の動力源と、複数の転動体の転動に伴って複数の直線軌道と平行に移動しつつ、ガラス板にスクライブ線を形成する本体とを備えたスクライブ装置であって、複数の転動体を機械的に連結する動力伝達機構を更に備えることに特徴付けられる。 In addition, an apparatus according to the present invention created to solve the above problems includes a plurality of linear tracks that are parallel to each other, a plurality of rolling elements that respectively roll along the plurality of linear tracks, and a plurality of rolling elements.

　以下、本発明の第一実施形態に係るスクライブ装置、及び、当該装置を用いた本発明の第一実施形態に係るガラス板の製造方法について説明する。 <First embodiment>
Hereinafter, the scribing apparatus according to the first embodiment of the present invention and the method for producing a glass plate according to the first embodiment of the present invention using the apparatus will be described.
　まず、スクライブ装置について説明する。 First, the scribe device will be described.
　図１に示すように、スクライブ装置１は、相互に平行な二本のラック２と、両ラック２，２に沿ってそれぞれ転動する二つのピニオン３と、相互に同期した状態で駆動しながら両ピニオン３，３に動力を付与する二基のサーボモーター４と、両ピニオン３，３を機械的に連結する動力伝達機構５と、両ピニオン３，３の転動に伴って両ラック２，２と平行なＶ方向に移動しつつ、ガラス板Ｇにスクライブ線Ｓを形成する本体６と、本体６のＶ方向への移動を案内する一対のガイド７，７と、スクライブ線Ｓの形成の前後でガラス板Ｇを搬送するベルトコンベア８とを備えている。 As shown in FIG. 1, the scribing device 1 is driven while being synchronized with two racks 2 that are parallel to each other and two pinions 3 that roll along the racks 2 and 2, respectively. Two servo motors 4 for applying power to both pinions 3, 3, a power transmission mechanism 5 for mechanically connecting both pinions 3, 3, and both racks 2, 2 along with the rolling of both pinions 3, 3 The main body 6 that forms the scribe line S on the glass plate G, the pair of guides 7 and 7 that guide the movement of the main body 6 in the V direction, and the scribe line S are formed. And a belt conveyor 8 that conveys the glass plate G in the front and rear directions.
　二本のラック２は、それぞれ定位置に固定された状態で水平に延びるように設置されている。 The two racks 2 are installed so as to extend horizontally while being fixed in place.
　二つのピニオン３の各々は、サーボモーター４の駆動軸４ａに取り付けられており、駆動軸４ａの回転に伴い動力（トルク）を得てラック２上を転動する。 Each of the two pinions 3 is attached to the drive shaft 4a of the servo motor 4 and rolls on the rack 2 by obtaining power (torque) with the rotation of the drive shaft 4a.
　二基のサーボモーター４は、二基のうちの一方の駆動軸４ａに取り付けられたピニオン３と、他方の駆動軸４ａに取り付けられたピニオン３とが、二本のラック２上で並走しながら転動するように、常に両ピニオン３，３に対して等しい大きさ、及び、等しい向きの動力を付与することが可能となっている。 In the two servo motors 4, the pinion 3 attached to one of the two drive shafts 4 a and the pinion 3 attached to the other drive shaft 4 a run in parallel on the two racks 2. However, it is possible to always apply power of equal magnitude and direction to both pinions 3 and 3 so as to roll.
　ここで、本実施形態に係るスクライブ装置１では、当該スクライブ装置１を構成する直線軌道および転動体として、それぞれラック２およびピニオン３を用いている。しかしながら、これに限定されるものではなく、例えば、直線軌道としてレールを用いると共に、転動体としてレール上を転動する車輪を用いてもよい。なお、レールと車輪とを用いる場合には、一対のガイド７，７は設置しなくてもよい。 Here, in the scribing apparatus 1 according to the present embodiment, the rack 2 and the pinion 3 are used as the linear track and the rolling elements constituting the scribing apparatus 1, respectively. However, it is not limited to this, For example, while using a rail as a linear track, you may use the wheel which rolls on a rail as a rolling element. In addition, when using a rail and a wheel, a pair of guides 7 and 7 do not need to be installed.
　また、本実施形態に係るスクライブ装置１では、当該スクライブ装置１を構成する動力源としてサーボモーター４を用いているが、汎用モーターを用いてもよい。なお、複数の動力源の動作を相互に同期させるコントローラにより、複数の動力源に対して同期制御を行うことが好ましい。 Further, in the scribe device 1 according to the present embodiment, the servo motor 4 is used as a power source constituting the scribe device 1, but a general-purpose motor may be used. In addition, it is preferable to perform synchronous control with respect to a several power source by the controller which synchronizes operation | movement of a several power source mutually.
　動力伝達機構５は、各サーボモーター４の駆動軸４ａに取り付けられた第一タイミングプーリー９と、駆動軸４ａと平行に延びた副軸１０（カウンターシャフト）、及び、副軸１０の両端にそれぞれ取り付けられた第二タイミングプーリー１１と、両プーリー９，１１に巻き掛けられたタイミングベルト１２とを備えている。 The power transmission mechanism 5 includes a first timing pulley 9 attached to the drive shaft 4a of each servo motor 4, a sub shaft 10 (counter shaft) extending in parallel with the drive shaft 4a, and both ends of the sub shaft 10. A second timing pulley 11 attached and a timing belt 12 wound around both pulleys 9 and 11 are provided.
　第一タイミングプーリー９は、同じ駆動軸４ａに取り付けられたピニオン３と同期して回転することが可能である。この第一タイミングプーリー９の径は、ピニオン３の径と比較して小さくなっている。 The first timing pulley 9 can rotate in synchronization with the pinion 3 attached to the same drive shaft 4a. The diameter of the first timing pulley 9 is smaller than the diameter of the pinion 3.
　第二タイミングプーリー１１は、駆動軸４ａの回転が第一タイミングプーリー９およびタイミングベルト１２を介して伝達されることで回転する。この第二タイミングプーリー１１の回転に伴い副軸１０が回転する。なお、第二タイミングプーリー１１の径は、第一タイミングプーリー９の径と同一となっている。 The second timing pulley 11 rotates when the rotation of the drive shaft 4 a is transmitted via the first timing pulley 9 and the timing belt 12. As the second timing pulley 11 rotates, the auxiliary shaft 10 rotates. The diameter of the second timing pulley 11 is the same as the diameter of the first timing pulley 9.
　ここで、本実施形態に係るスクライブ装置１では、両プーリー９，１１とタイミングベルト１２とにより、駆動軸４ａの回転が副軸１０に伝達される構成となっているが、この限りではない。例えば、駆動軸４ａと副軸１０との双方に歯車を取り付け、両歯車を噛み合わせることで駆動軸４ａの回転が副軸１０に伝達される構成としてもよい。 Here, in the scribing apparatus 1 according to the present embodiment, the rotation of the drive shaft 4a is transmitted to the auxiliary shaft 10 by the pulleys 9 and 11 and the timing belt 12, but this is not restrictive. For example, gears may be attached to both the drive shaft 4a and the sub shaft 10, and the rotation of the drive shaft 4a may be transmitted to the sub shaft 10 by meshing both gears.
　本体６は、両サーボモーター４，４がそれぞれ固定された二つの固定部６ａと、駆動軸４ａおよび副軸１０の軸方向に沿って延びると共に、両固定部６ａ，６ａを連結する連結部６ｂと、ガラス板Ｇ上を走行する一対のホイールカッター６ｃａ，６ｃａが取り付けられ、且つ、連結部６ｂと一体に移動する筐体６ｃとを備えている。 The main body 6 extends along the axial direction of the drive shaft 4a and the countershaft 10 with the two servomotors 4 and 4 fixed to each other, and a connecting portion 6b that connects both the fixed portions 6a and 6a. And a pair of wheel cutters 6ca and 6ca that travel on the glass plate G, and a housing 6c that moves integrally with the connecting portion 6b.
　連結部６ｂは、副軸１０を回転自在に支持するための複数（ここでは四つ）の軸受６ｂａを有する。なお、連結部６ｂは、駆動軸４ａと副軸１０との間に介在しており、駆動軸４ａは連結部６ｂを基準として本体６の移動方向（Ｖ方向）の前方側に配置され、副軸１０は移動方向の後方側に配置されている。 The connecting portion 6b has a plurality of (here, four) bearings 6ba for rotatably supporting the auxiliary shaft 10. The connecting portion 6b is interposed between the drive shaft 4a and the auxiliary shaft 10, and the driving shaft 4a is disposed on the front side in the movement direction (V direction) of the main body 6 with respect to the connecting portion 6b. The shaft 10 is disposed on the rear side in the moving direction.
　筐体６ｃに取り付けられた一対のホイールカッター６ｃａ，６ｃａは、それぞれ切断予定線Ｘ（後で折割りにより切断される箇所となる線）に沿って走行しながらスクライブ線Ｓを形成する。 The pair of wheel cutters 6ca and 6ca attached to the housing 6c form a scribe line S while traveling along a planned cutting line X (a line to be cut later by splitting).
　一対のガイド７，７は、二本のラック２の相互間で両ラック２，２と平行に延びるように設置されている。各ガイド７には、当該ガイド７に沿って移動が可能なブロック（図示省略）が取り付けられている。このブロックは、筐体６ｃの底部に固定されており、本体６（筐体６ｃ）は、ブロックを介してガイド７に案内されて移動する。 The pair of guides 7 and 7 are installed between the two racks 2 so as to extend in parallel with the racks 2 and 2. Each guide 7 is provided with a block (not shown) that can move along the guide 7. This block is fixed to the bottom of the housing 6c, and the main body 6 (housing 6c) moves while being guided by the guide 7 through the block.
　ベルトコンベア８は、一対のガイド７，７の相互間に配置されると共に、その送り方向がＶ方向と平行になっている。ベルトコンベア８における搬送面の高さ位置は、一対のガイド７，７が設置された高さ位置よりも下方となっている。このベルトコンベア８は、スクライブ線Ｓの形成前のガラス板Ｇを形成位置（図１でガラス板Ｇが描かれた位置）に搬入して停止させると共に、スクライブ線Ｓの形成後のガラス板Ｇを形成位置から搬出するように構成されている。 The belt conveyor 8 is disposed between the pair of guides 7 and 7 and the feeding direction is parallel to the V direction. The height position of the conveying surface of the belt conveyor 8 is lower than the height position where the pair of guides 7 and 7 are installed. This belt conveyor 8 carries in and stops the glass plate G before forming the scribe line S at the formation position (the position where the glass plate G is drawn in FIG. 1) and stops the glass plate G after forming the scribe line S. It is comprised so that it may carry out from a formation position.
　なお、以上に説明したスクライブ装置１は、二本のラック２と平行に延びる対称軸Ｃを基準として対称な構成を有しており、このスクライブ装置１の重心は対称軸Ｃ上に位置している。 The scribing apparatus 1 described above has a symmetric configuration with respect to an axis of symmetry C extending in parallel with the two racks 2, and the center of gravity of the scribing apparatus 1 is located on the axis of symmetry C. Yes.
　次に、上記のスクライブ装置１を用いたガラス板の製造方法について説明する。 Next, a method for producing a glass plate using the scribe device 1 will be described.
　なお、本実施形態においてスクライブ線Ｓを形成される対象のガラス板Ｇは、矩形状に形成されている。このガラス板Ｇは、四辺のうちの平行な二辺が方向Ｖと平行に延びた状態でベルトコンベア８に積載されている。 In this embodiment, the target glass plate G on which the scribe line S is formed is formed in a rectangular shape. The glass plate G is stacked on the belt conveyor 8 with two parallel sides of the four sides extending in parallel with the direction V.
　はじめに、ガラス板Ｇをベルトコンベア８により形成位置に搬入して停止させる。次いで、二基のサーボモーター４の駆動に伴って本体６をＶ方向に移動させることで、ガラス板Ｇ上を走行する一対のホイールカッター６ｃａ，６ｃａにより、Ｖ方向と平行に二本のスクライブ線Ｓを形成する。その後、スクライブ線Ｓが形成されたガラス板Ｇをベルトコンベア８により形成位置から搬出する。搬出されたガラス板Ｇは、後工程に供される。後工程では、スクライブ線Ｓを起点とした折割りや、端面加工、洗浄処理等が行われる。 First, the glass plate G is carried into the forming position by the belt conveyor 8 and stopped. Next, by moving the main body 6 in the V direction as the two servo motors 4 are driven, a pair of wheel cutters 6ca and 6ca running on the glass plate G are used to drive two scribe lines in parallel with the V direction. S is formed. Thereafter, the glass plate G on which the scribe line S is formed is unloaded from the forming position by the belt conveyor 8. The unloaded glass plate G is subjected to a subsequent process. In the post-process, folding with the scribe line S as a starting point, end face processing, cleaning processing, and the like are performed.
　次に、本実施形態に係るスクライブ装置１、及び、ガラス板の製造方法による主たる作用・効果について説明する。 Next, main actions and effects of the scribing apparatus 1 according to this embodiment and the glass plate manufacturing method will be described.
　上記のスクライブ装置１、及び、ガラス板の製造方法では、二本のラック２に沿ってそれぞれ転動する二つのピニオン３を動力伝達機構５により機械的に連結している。そのため、両ピニオン３，３に動力を付与する二基のサーボモーター４の相互間で動作にずれが発生した場合や、一部のサーボモーター４とピニオン３との間に滑りが発生した場合でも、一方のピニオン３が、他方のピニオン３に対して先行するような事態の発生を回避できる。これにより、ガラス板Ｇにスクライブ線Ｓを形成する本体６が、不当に傾くことを防止できる。その結果、スクライブ線Ｓの形成不良を回避することが可能となる。 In the scribing apparatus 1 and the glass plate manufacturing method, two pinions 3 that roll along the two racks 2 are mechanically connected by a power transmission mechanism 5. Therefore, even when a deviation occurs in the operation between the two servo motors 4 that apply power to both pinions 3 and 3, or even when a slip occurs between some of the servo motors 4 and the pinions 3. The occurrence of a situation in which one pinion 3 precedes the other pinion 3 can be avoided. Thereby, it can prevent that the main body 6 which forms the scribe line S in the glass plate G inclines unjustly. As a result, it is possible to avoid the formation failure of the scribe line S.
　また、二基のサーボモーター４の一方が故障した場合であっても、他方のサーボモーター４が動作していれば、本体６を適当に移動させることができ、ガラス板Ｇにスクライブ線Ｓを形成することができる。このため、サーボモーター４の故障による生産量の低下を防止できる。 Further, even if one of the two servo motors 4 fails, if the other servo motor 4 is operating, the main body 6 can be moved appropriately, and the scribe line S is placed on the glass plate G. Can be formed. For this reason, it is possible to prevent a decrease in production due to a failure of the servo motor 4.
＜第二実施形態＞
　以下、本発明の第二実施形態に係るスクライブ装置、及び、当該装置を用いた本発明の第二実施形態に係るガラス板の製造方法について説明する。 <Second embodiment>
Hereinafter, the scribing apparatus according to the second embodiment of the present invention and the method for producing a glass plate according to the second embodiment of the present invention using the apparatus will be described.
　まず、スクライブ装置について説明する。なお、第二実施形態に係るスクライブ装置については、上記の第一実施形態に係るスクライブ装置との相違点についてのみ説明する。第一実施形態に係るスクライブ装置との共通点については、第二実施形態に係るスクライブ装置の説明で参照する図面に同一の符号を付すことで重複する説明を省略する。 First, the scribe device will be described. In addition, about the scribing apparatus which concerns on 2nd embodiment, only a different point from scribing apparatus which concerns on said 1st embodiment is demonstrated. About a common point with the scribing apparatus which concerns on 1st embodiment, the overlapping description is abbreviate | omitted by attaching | subjecting the same code | symbol to drawing referred in description of the scribing apparatus which concerns on 2nd embodiment.
　図２に示すように、第二実施形態に係るスクライブ装置１が、第一実施形態に係るスクライブ装置１と相違している主な点は、両ピニオン３，３を機械的に連結する動力伝達機構５が単一の軸１３のみで構成されている点と、この単一の軸１３を介して二基のサーボモーター４から二つのピニオン３に動力を付与している点である。 As shown in FIG. 2, the main difference between the scribing device 1 according to the second embodiment and the scribing device 1 according to the first embodiment is that power transmission that mechanically couples both pinions 3 and 3. The mechanism 5 is composed of only a single shaft 13 and the point that power is applied to the two pinions 3 from the two servo motors 4 via the single shaft 13.
　軸１３は、筐体６ｃに取り付けられた複数（ここでは二つ）の軸受６ｂａにより回転自在に支持されると共に、この軸１３には、二つのタイミングプーリー１４が取り付けられている。二基のサーボモーター４は共に筐体６ｃに搭載されている。両サーボモーター４，４の各々における駆動軸４ａには、タイミングプーリー１５が取り付けられている。そして、軸１３側のタイミングプーリー１４とサーボモーター４側のタイミングプーリー１５とに、タイミングベルト１６が巻き掛けられている。 The shaft 13 is rotatably supported by a plurality of (here, two) bearings 6ba attached to the housing 6c, and two timing pulleys 14 are attached to the shaft 13. Both servo motors 4 are mounted on the housing 6c. A timing pulley 15 is attached to the drive shaft 4a of each of the servomotors 4 and 4. A timing belt 16 is wound around a timing pulley 14 on the shaft 13 side and a timing pulley 15 on the servo motor 4 side.
　これにより、両サーボモーター４，４の各々における駆動軸４ａの回転が、両プーリー１４，１５とタイミングベルト１６とにより軸１３に伝達される。そして、軸１３と同期して当該軸１３の両端に取り付けられた両ピニオン３，３が回転することにより、各ピニオン３がラック２上を転動する。 Thus, the rotation of the drive shaft 4a in each of the servo motors 4 and 4 is transmitted to the shaft 13 by the pulleys 14 and 15 and the timing belt 16. Then, both pinions 3, 3 attached to both ends of the shaft 13 rotate in synchronization with the shaft 13, so that each pinion 3 rolls on the rack 2.
　上記のスクライブ装置１を用いた第二実施形態に係るガラス板の製造方法は、第一実施形態と同様にして実行できるため、ここでは重複する説明を省略する。さらに、第二実施形態に係るガラス板の製造方法によれば、第一実施形態と同様の主たる作用・効果を得ることが可能である。 Since the manufacturing method of the glass plate which concerns on 2nd embodiment using said scribing apparatus 1 can be performed similarly to 1st embodiment, the overlapping description is abbreviate | omitted here. Furthermore, according to the manufacturing method of the glass plate which concerns on 2nd embodiment, it is possible to acquire the main effect | action and effect similar to 1st embodiment.
　ここで、本発明に係るスクライブ装置やガラス板の製造方法は、上記の各実施形態で説明した構成や態様に限定されるものではない。例えば、上記の各実施形態では、ガラス板に対してスクライブ線を一方向に沿ってのみ形成しているが、これに限定されるものではない。一例を挙げると、相互に直交する二方向（矩形のガラス板の縦方向および横方向等）に沿ってガラス板にスクライブ線を形成してもよい。この場合、上記の各実施形態に用いたスクライブ装置を上下二段に配置すると共に、両装置の本体の移動方向が相互に直交する方向となるように配置すればよい。 Here, the scribing apparatus and the glass plate manufacturing method according to the present invention are not limited to the configurations and aspects described in the above embodiments. For example, in each of the above embodiments, the scribe line is formed only in one direction with respect to the glass plate, but the present invention is not limited to this. As an example, scribe lines may be formed on the glass plate along two directions orthogonal to each other (for example, the vertical direction and the horizontal direction of the rectangular glass plate). In this case, the scribing devices used in the above-described embodiments may be arranged in two upper and lower stages, and the moving directions of the main bodies of both devices may be arranged so as to be orthogonal to each other.
