Description

ガラスロールの製造方法Manufacturing method of glass roll
　本発明は、ガラスロールを製造する方法に関する。 The present invention relates to a method for manufacturing a glass roll.
　近年、急速に普及しているスマートフォンやタブレット型ＰＣ等のモバイル端末は、薄型、軽量であることが求められるため、これらの端末に組み込まれるガラス基板にも薄板化に対する要請が高まっている。このような現状の下、フィルム状にまで薄板化（例えば、厚みが３００μｍ以下）されたガラス基板であるガラスフィルムが開発、製造されるに至っている。 In recent years, mobile terminals such as smartphones and tablet PCs, which are rapidly becoming widespread, are required to be thin and lightweight, so there is an increasing demand for thinning glass substrates incorporated in these terminals. Under such circumstances, a glass film, which is a glass substrate thinned to a film shape (for example, a thickness of 300 μm or less), has been developed and manufactured.
　ガラスフィルムの製造工程には、これの元となる帯状の母材ガラスフィルムをロール状に巻き取ってガラスロールを製造する工程が含まれる場合がある。例えば特許文献１には、成形工程と、耳部除去工程と、第一巻取工程と、取出工程と、割断工程と、第二巻取工程と、を備えるガラスロールの製造方法が開示されている。 The glass film manufacturing process may include a process of winding a strip-shaped base glass film, which is the basis of the glass film, into a roll to manufacture a glass roll. For example, Patent Document 1 discloses a method for manufacturing a glass roll including a molding step, an ear removal step, a first winding step, a taking-out step, a cutting step, and a second winding step. There is.
　この製造方法では、まず、成形工程において、オーバーフローダウンドロー法により母材ガラスフィルムを連続的に成形する。次に、耳部除去工程において、母材ガラスフィルムにレーザ照射装置からレーザ光を照射し、母材ガラスフィルムの幅方向両端に位置する不要な耳部を除去することで、第一ガラスフィルムを形成する。第一巻取工程では、この第一ガラスフィルムを巻芯により巻き取ることで、第一ガラスロールが形成される。 In this manufacturing method, first, in the molding process, the base glass film is continuously molded by the overflow down draw method. Next, in the selvage removal step, the base glass film is irradiated with laser light from a laser irradiation device to remove unnecessary selvage portions located at both ends in the width direction of the base glass film, whereby the first glass film is formed. Form. In the first winding step, the first glass roll is formed by winding the first glass film with a winding core.
　その後、取出工程において、第一ガラスロールからガラスフィルムが取り出され、割断工程において、レーザ照射装置からレーザ光をこの第一ガラスフィルムに照射する。これにより、第一ガラスフィルムの幅方向の端部が不要部分（非製品部）として除去され、第二ガラスフィルムが形成される。最後に、第二巻取工程において、第二ガラスフィルムを巻芯により巻き取ることで、第二ガラスロールが製造される。 After that, in the taking-out step, the glass film is taken out from the first glass roll, and in the cutting step, the laser beam is irradiated to the first glass film from the laser irradiation device. As a result, the widthwise end portion of the first glass film is removed as an unnecessary portion (non-product portion), and the second glass film is formed. Finally, in the second winding step, the second glass roll is manufactured by winding the second glass film with the winding core.

　上記のようなガラスロールの製造方法において、割断工程後に搬送される第二ガラスフィルムに斜行や蛇行が発生する場合がある。これは、第二ガラスフィルムにおける幅方向の一端部の長さと、幅方向の他端部の長さとが異なることに起因する。斜行や蛇行の程度が大きくなると、上流側の割断工程に好ましくない影響を与える場合がある。 In the glass roll manufacturing method as described above, skewing or meandering may occur in the second glass film conveyed after the cutting process. This is because the length of one end in the width direction and the length of the other end in the width direction of the second glass film are different. If the degree of skewing or meandering becomes large, it may adversely affect the cutting process on the upstream side.
　すなわち、第二ガラスフィルムに斜行や蛇行が生じると、第二ガラスフィルムの上流側の部分が下流側の部分によって引っ張られて破損する場合があった。また、第二ガラスフィルムの上流側の部分が、第一ガラスフィルムから分離された不要部分に接触して破損する場合があった。 That is, when skewing or meandering occurs in the second glass film, the upstream part of the second glass film may be pulled and damaged by the downstream part. In addition, the upstream portion of the second glass film may come into contact with an unnecessary portion separated from the first glass film and be damaged.
　本発明は上記の事情に鑑みてなされたものであり、ガラスフィルムを搬送する際の蛇行や斜行を抑制することを技術的課題とする。 The present invention has been made in view of the above circumstances, and it is a technical subject to suppress meandering and skewing when transporting a glass film.
　本発明は上記の課題を解決するためのものであり、ガラスロールの製造方法であって、ガラスフィルムを供給する供給工程と、前記ガラスフィルムにレーザ照射装置からレーザ光を照射することにより、前記ガラスフィルムの一部を切断する切断工程と、前記切断工程後の前記ガラスフィルムを巻取装置によってロール状に巻き取る巻取工程と、前記レーザ照射装置と前記巻取装置との間に設けられる下流側調整装置によって、前記切断工程後の前記ガラスフィルムの位置を調整する下流側調整工程と、を備えることを特徴とする。 The present invention is for solving the above-mentioned problems, and is a method for manufacturing a glass roll, which comprises a supply step of supplying a glass film and irradiating the glass film with a laser beam from a laser irradiation device. It is provided between the cutting step of cutting a part of the glass film, the winding step of winding the glass film in a roll shape by the winding device after the cutting step, and the laser irradiation device and the winding device. It is characterized by comprising a downstream side adjusting step of adjusting the position of the glass film after the cutting step by the downstream side adjusting device.
　既述のように、切断工程によって形成されたガラスフィルムについては、幅方向の一端部の長さと、幅方向の他端部の長さとが異なる場合がある。本方法では、下流側調整工程（下流側調整装置）によって、ガラスフィルムの一端部の長さと他端部の長さとの差が過大とならないように当該ガラスフィルムの位置を調整することで、ガラスフィルムを搬送する際の斜行や蛇行を抑制することが可能となる。これにより、上流側のレーザ照射装置による切断工程に悪影響を及ぼすのを防止することができる。 As described above, for the glass film formed by the cutting process, the length of one end in the width direction and the length of the other end in the width direction may be different. In this method, the glass is adjusted by the downstream adjustment step (downstream adjustment device) by adjusting the position of the glass film so that the difference between the length of one end and the length of the other end of the glass film does not become excessive. It is possible to suppress skewing and meandering when transporting the film. This makes it possible to prevent adverse effects on the cutting process by the laser irradiation device on the upstream side.
　本方法における前記供給工程では、前記ガラスフィルムをロール状に巻き取ってなるガラスロールから前記ガラスフィルムを送り出すことが可能な巻出装置によって前記ガラスフィルムを供給してもよく、本方法は、前記巻出装置と前記レーザ照射装置との間に設けられる上流側調整装置によって、前記巻出装置から供給される前記ガラスフィルムの位置を調整する上流側調整工程を備えてもよい。 In the supply step in the present method, the glass film may be supplied by a winding device capable of delivering the glass film from a glass roll formed by winding the glass film in a roll shape, and the present method is described. An upstream adjustment step of adjusting the position of the glass film supplied from the unwinding device by the upstream adjusting device provided between the unwinding device and the laser irradiation device may be provided.
　巻出装置からレーザ照射装置に供給されるガラスフィルムは、その幅方向の一端部の長さと、幅方向の他端部の長さとが異なる場合がある。この長さの差が過大となると、レーザ照射装置に供給されたガラスフィルムに皺が発生し、ガラスフィルムの切断を阻害するおそれがある。本方法では、上流側調整工程によって、上記の長さの差が過大とならないようにガラスフィルムの位置を調整することで、切断工程においてこのガラスフィルムを精度良く切断することが可能となる。 The length of one end in the width direction of the glass film supplied from the unwinding device to the laser irradiation device may differ from the length of the other end in the width direction. If this difference in length is excessive, wrinkles may occur in the glass film supplied to the laser irradiation device, which may hinder the cutting of the glass film. In this method, by adjusting the position of the glass film so that the above difference in length is not excessive by the upstream side adjustment step, it is possible to cut the glass film with high accuracy in the cutting step.
　本方法において、前記切断工程後の前記ガラスフィルムに対する前記下流側調整装置による位置調整量は、前記巻出装置から供給された前記ガラスフィルムに対する前記上流側調整装置による位置調整量よりも小さくてもよい。この構成によれば、上流側調整装置によって相対的に大きくガラスフィルムの位置調整を行うことができ、下流側調整装置によってガラスフィルムの位置の微調整を行うことができる。これにより、レーザ照射装置による切断工程に悪影響が及ぶのを防止することができる。 In this method, even if the position adjustment amount of the glass film after the cutting step by the downstream side adjusting device is smaller than the position adjusting amount of the glass film supplied from the unwinding device by the upstream side adjusting device. good. According to this configuration, the position of the glass film can be adjusted relatively large by the upstream side adjusting device, and the position of the glass film can be finely adjusted by the downstream side adjusting device. This makes it possible to prevent the cutting process by the laser irradiation device from being adversely affected.
　本方法は、前記レーザ照射装置と前記下流側調整装置との間に設けられる吸着ベルトコンベアによって、前記切断工程後の前記ガラスフィルムの位置決めを行う位置決め工程を備えてもよい。 This method may include a positioning step of positioning the glass film after the cutting step by a suction belt conveyor provided between the laser irradiation device and the downstream side adjusting device.
　位置決め工程によってガラスフィルムの位置ずれを防止することで、吸着ベルトコンベアの上流側での切断工程において、ガラスフィルムの切断を精度良く行うことが可能となる。 By preventing the position of the glass film from shifting by the positioning process, it is possible to cut the glass film with high accuracy in the cutting process on the upstream side of the suction belt conveyor.
　前記下流側調整装置は、前記切断工程後の前記ガラスフィルムに対して抱き角を有するように接触する搬送ローラを備えてもよい。これにより、下流側調整工程におけるガラスフィルムの位置調整を確実に行うことができる。 The downstream side adjusting device may include a transport roller that comes into contact with the glass film after the cutting step so as to have a holding angle. This makes it possible to reliably adjust the position of the glass film in the downstream side adjustment step.
　前記上流側調整装置は、前記巻出装置から供給された前記ガラスフィルムに対して抱き角を有するように接触する搬送ローラを備えてもよい。これにより、上流側調整工程におけるガラスフィルムの位置調整を確実に行うことができる。 The upstream side adjusting device may include a transport roller that contacts the glass film supplied from the unwinding device so as to have a holding angle. This makes it possible to reliably adjust the position of the glass film in the upstream side adjustment step.
　本発明によれば、ガラスフィルムを搬送する際の蛇行や斜行を抑制することができる。 According to the present invention, it is possible to suppress meandering and skewing when transporting a glass film.

　以下、上記構成の製造装置１を使用して第二ガラスロールＧＲＬ２を製造する方法について説明する。 Hereinafter, a method of manufacturing the second glass roll GRL2 using the manufacturing apparatus 1 having the above configuration will be described.
　図５に示すように、本方法は、成形工程Ｓ１と、第一切断工程Ｓ２と、第一巻取工程Ｓ３と、供給工程Ｓ４と、第二切断工程Ｓ５と、下流側調整工程Ｓ６と、第二巻取工程Ｓ７と、を備える。 As shown in FIG. 5, this method includes a molding step S1, a first cutting step S2, a first winding step S3, a supply step S4, a second cutting step S5, and a downstream adjustment step S6. The second winding step S7 is provided.
　成形工程Ｓ１では、成形部２における成形体１１のオーバーフロー溝１１ａから溢れ出した溶融ガラスＧＭを成形体１１の両側面に沿ってそれぞれ流下させ、その下端で合流させてフィルム状に成形する。 In the molding step S1, the molten glass GM overflowing from the overflow groove 11a of the molded body 11 in the molded body 2 is allowed to flow down along both side surfaces of the molded body 11 and merged at the lower ends thereof to form a film.
　この際、溶融ガラスＧＭの幅方向収縮をエッジローラ１２により規制して所定幅の母材ガラスフィルムＧとする。その後、母材ガラスフィルムＧに対してアニーラ１３により除歪処理を施す（徐冷工程）。支持ローラ１５の張力により、母材ガラスフィルムＧは所定の厚みに形成される。 At this time, the shrinkage of the molten glass GM in the width direction is regulated by the edge roller 12 to obtain the base glass film G having a predetermined width. After that, the base glass film G is subjected to strain-removing treatment with the annealing 13 (slow cooling step). The base glass film G is formed to a predetermined thickness by the tension of the support roller 15.
　第一切断工程Ｓ２では、方向変換部３及び第一搬送部４によって母材ガラスフィルムＧを横搬送方向Ｘ１に沿って搬送しつつ、第一切断部５において、第一レーザ照射装置１８からレーザ光Ｌを母材ガラスフィルムＧの一部に照射する。 In the first cutting step S2, the base glass film G is conveyed along the lateral transfer direction X1 by the direction changing unit 3 and the first transfer unit 4, and the laser is emitted from the first laser irradiation device 18 in the first cutting unit 5. Light L is applied to a part of the base glass film G.
　上記のようなレーザ光Ｌの照射により、母材ガラスフィルムＧが加熱される。その後、母材ガラスフィルムＧのうち加熱された部分は、第一冷却装置１９の直下に到達すると、第一冷却装置１９から下方に向けて噴射された冷媒Ｒを受けて冷却される。 The base glass film G is heated by the irradiation of the laser beam L as described above. After that, when the heated portion of the base glass film G reaches directly under the first cooling device 19, it receives the refrigerant R jetted downward from the first cooling device 19 and is cooled.
　第一レーザ照射装置１８の局部加熱による膨張と第一冷却装置１９の冷却による収縮とにより、母材ガラスフィルムＧに熱応力が生じる。母材ガラスフィルムＧには、予め初期クラックが形成されており、このクラックを熱応力によって進展させる。これにより、母材ガラスフィルムＧの幅方向における両端部（耳部）が非製品部Ｇｓとして母材ガラスフィルムＧから分離され、第一ガラスフィルムＧ１が形成される。 Thermal stress is generated in the base glass film G due to the expansion of the first laser irradiation device 18 due to local heating and the contraction of the first cooling device 19 due to cooling. Initial cracks are formed in advance in the base glass film G, and these cracks are propagated by thermal stress. As a result, both ends (ears) of the base glass film G in the width direction are separated from the base glass film G as non-product portions Gs, and the first glass film G1 is formed.
　第一巻取工程Ｓ３では、第一巻取装置６において第一ガラスフィルムＧ１を巻芯２０に巻き取ることで、第一ガラスロールＧＲＬ１が形成される。その後、第一ガラスロールＧＲＬ１は、第一巻取装置６から取り外され、巻出装置７へと移送される。 In the first winding step S3, the first glass roll GRL1 is formed by winding the first glass film G1 around the winding core 20 in the first winding device 6. After that, the first glass roll GRL1 is removed from the first winding device 6 and transferred to the unwinding device 7.
　供給工程Ｓ４では、巻出装置７に装着された第一ガラスロールＧＲＬ１から第一ガラスフィルムＧ１が送り出される。第一ガラスフィルムＧ１は、第二搬送部８の搬送ローラ２１を介して上方Ｚ１へと搬送される。その後、第一ガラスフィルムＧ１は、上流側コンベア２２により、横搬送方向Ｘ２に沿って第二切断部９へと搬送される。 In the supply process S4, the first glass film G1 is sent out from the first glass roll GRL1 mounted on the unwinding device 7. The first glass film G1 is conveyed upward to Z1 via the transfer roller 21 of the second transfer unit 8. After that, the first glass film G1 is conveyed to the second cutting portion 9 along the lateral transfer direction X2 by the upstream conveyor 22.
　第二切断工程Ｓ５では、上流側コンベア２２によって第一ガラスフィルムＧ１を横搬送方向Ｘ２に沿って搬送しつつ、第一ガラスフィルムＧ１の一部に、第二レーザ照射装置３０によりレーザ光Ｌを照射する。 In the second cutting step S5, the first glass film G1 is conveyed along the lateral transfer direction X2 by the upstream conveyor 22, and the laser beam L is transmitted to a part of the first glass film G1 by the second laser irradiation device 30. Irradiate.
　上記のようなレーザ光Ｌの照射により、第一ガラスフィルムＧ１が加熱される。その後、第一ガラスフィルムＧ１のうち加熱された部分は、第二冷却装置３１の直下に到達すると、第二冷却装置３１から下方に向けて噴射された冷媒Ｒを受けて冷却される。 The first glass film G1 is heated by the irradiation of the laser beam L as described above. After that, when the heated portion of the first glass film G1 reaches directly under the second cooling device 31, it receives the refrigerant R jetted downward from the second cooling device 31 and is cooled.
　第二レーザ照射装置３０の局部加熱による膨張と第二冷却装置３１の冷却による収縮とにより、第一ガラスフィルムＧ１に熱応力が生じる。第一ガラスフィルムＧ１には、予め初期クラックが形成されており、このクラックを熱応力によって進展させる。これにより、第一ガラスフィルムＧ１の幅方向Ｙにおける両端部Ｇａ，Ｇｂが非製品部Ｇｓとして第一ガラスフィルムＧ１から分離し、第二ガラスフィルムＧ２が形成される。 Thermal stress is generated in the first glass film G1 due to the expansion of the second laser irradiation device 30 due to local heating and the contraction of the second cooling device 31 due to cooling. Initial cracks are formed in advance in the first glass film G1, and these cracks are propagated by thermal stress. As a result, both ends Ga and Gb of the first glass film G1 in the width direction Y are separated from the first glass film G1 as non-product portions Gs, and the second glass film G2 is formed.
　下流側コンベア２３は、第二ベルト２８によって第二ガラスフィルムＧ２を吸着しながら下流側に搬送する。これにより、第二ガラスフィルムＧ２に位置ずれが生じないように、第二ガラスフィルムＧ２の位置決めが行われる（位置決め工程）。このように、下流側コンベア２３によって第二ガラスフィルムＧ２の位置決めを行うことで、上流側の切断位置において、第一ガラスフィルムＧ１を精度良く切断することが可能となる。 The downstream side conveyor 23 is conveyed to the downstream side while adsorbing the second glass film G2 by the second belt 28. As a result, the second glass film G2 is positioned so that the second glass film G2 does not shift in position (positioning step). By positioning the second glass film G2 by the downstream conveyor 23 in this way, it is possible to accurately cut the first glass film G1 at the cutting position on the upstream side.
　下流側調整工程Ｓ６では、下流側コンベア２３よりも下流側で搬送される第二ガラスフィルムＧ２の斜行や蛇行を抑制するために、この第二ガラスフィルムＧ２の位置を下流側調整装置２４によって調整する。 In the downstream side adjusting step S6, in order to suppress the skewing and meandering of the second glass film G2 conveyed on the downstream side of the downstream side conveyor 23, the position of the second glass film G2 is adjusted by the downstream side adjusting device 24. adjust.
　第二ガラスフィルムＧ２の斜行や蛇行は、この第二ガラスフィルムＧ２の幅方向Ｙにおける一端部Ｇａの長さと、幅方向Ｙにおける他端部Ｇｂの長さとの違いにより発生し得る。下流側調整工程Ｓ６では、この長さの差が過大とならないように、下流側調整装置２４の搬送ローラ３４の姿勢を変更することによって、第二ガラスフィルムＧ２の位置を調整する。 The skewing or meandering of the second glass film G2 may occur due to the difference between the length of one end Ga in the width direction Y of the second glass film G2 and the length of the other end Gb in the width direction Y. In the downstream side adjusting step S6, the position of the second glass film G2 is adjusted by changing the posture of the transport roller 34 of the downstream side adjusting device 24 so that the difference in length does not become excessive.
　具体的には、図６に示すように、下流側調整装置２４は、搬送ローラ３４を、第一の軸Ａ１が第二ガラスフィルムＧ２の幅方向Ｙと平行となる基準姿勢（実線で示す姿勢）から、第二の軸Ａ２まわりに所定の角度θ１だけ回動した調整姿勢（二点鎖線で示す姿勢）へと変更する。これにより、幅方向Ｙにおける第二ガラスフィルムＧ２の位置が調整される。この搬送ローラ３４の位置調整量（位置調整角度θ１）は、第二ガラスフィルムＧ２の幅寸法や各端部Ｇａ，Ｇｂの長さの差に応じて適宜設定される。 Specifically, as shown in FIG. 6, the downstream side adjusting device 24 arranges the transport roller 34 in a reference posture (a posture shown by a solid line) in which the first axis A1 is parallel to the width direction Y of the second glass film G2. ) Is changed to an adjustment posture (posture indicated by a two-dot chain line) rotated by a predetermined angle θ1 around the second axis A2. As a result, the position of the second glass film G2 in the width direction Y is adjusted. The position adjustment amount (position adjustment angle θ1) of the transfer roller 34 is appropriately set according to the width dimension of the second glass film G2 and the difference in the lengths of the end portions Ga and Gb.
　また、第二搬送部８は、下流側調整装置２４によって第二ガラスフィルムＧ２の搬送方向を横搬送方向Ｘ２から下方Ｚ２へと変換し、下流側の搬送ローラ２５によって第二ガラスフィルムＧ２を第二巻取装置１０に向かって搬送する。 Further, the second transport unit 8 converts the transport direction of the second glass film G2 from the lateral transport direction X2 to the lower Z2 by the downstream side adjusting device 24, and transfers the second glass film G2 by the downstream side transport roller 25. It is conveyed toward the two-winding device 10.
　第二巻取工程Ｓ７では、第二巻取装置１０において、巻芯３９によって第二ガラスフィルムＧ２が巻き取られる。所定長さの第二ガラスフィルムＧ２が巻き取られることで、第二巻取装置１０に第二ガラスロールＧＲＬ２が形成される。 In the second winding step S7, the second glass film G2 is wound by the winding core 39 in the second winding device 10. By winding the second glass film G2 having a predetermined length, the second glass roll GRL2 is formed on the second winding device 10.
　以上説明した本実施形態に係る第二ガラスロールＧＲＬ２の製造方法によれば、下流側調整工程Ｓ６（下流側調整装置２４）によって第二ガラスフィルムＧ２の位置を調整することで、第二ガラスフィルムＧ２を搬送する際の斜行や蛇行を抑制することが可能となる。これにより、第二切断部９に第二ガラスフィルムＧ２の斜行や蛇行による悪影響が及ぶのを防止することができる。また、下流側調整装置２４の搬送ローラ３４は、第二ガラスフィルムＧ２に対する抱き角を有することで、当該第二ガラスフィルムＧ２の位置調整を確実に行うことができる。 According to the method for manufacturing the second glass roll GRL2 according to the present embodiment described above, the position of the second glass film G2 is adjusted by the downstream side adjusting step S6 (downstream side adjusting device 24) to adjust the position of the second glass film G2. It is possible to suppress skewing and meandering when transporting G2. As a result, it is possible to prevent the second cut portion 9 from being adversely affected by the skewing or meandering of the second glass film G2. Further, since the transport roller 34 of the downstream side adjusting device 24 has a holding angle with respect to the second glass film G2, the position of the second glass film G2 can be surely adjusted.

　図９に示すように、本方法は、成形工程Ｓ１１と、第一切断工程Ｓ１２と、第一巻取工程Ｓ１３と、供給工程Ｓ１４と、上流側調整工程Ｓ１５と、第二切断工程Ｓ１６と、下流側調整工程Ｓ１７と、第二巻取工程Ｓ１８と、を備える。以下、本方法において、第一実施形態と異なる点について説明する。 As shown in FIG. 9, this method includes a molding step S11, a first cutting step S12, a first winding step S13, a supply step S14, an upstream adjustment step S15, and a second cutting step S16. A downstream side adjusting step S17 and a second winding step S18 are provided. Hereinafter, the points different from the first embodiment in this method will be described.
　上流側調整工程Ｓ１５では、巻出装置７から送り出された第一ガラスフィルムＧ１が上流側調整装置４０に供給される。 In the upstream side adjusting step S15, the first glass film G1 sent out from the unwinding device 7 is supplied to the upstream side adjusting device 40.
　第一ガラスフィルムＧ１は、その幅方向Ｙにおける一端部Ｇａの長さと、幅方向Ｙにおける他端部Ｇｂの長さとが異なる。この長さの差が大きくなると、第二切断部９に供給される第一ガラスフィルムＧ１の一部に皺が発生し、第二切断部９による切断を阻害するおそれがある。 The length of one end Ga in the width direction Y of the first glass film G1 is different from the length of the other end Gb in the width direction Y. If this difference in length becomes large, wrinkles may occur in a part of the first glass film G1 supplied to the second cutting portion 9, and the cutting by the second cutting portion 9 may be hindered.
　上流側調整装置４０は、第二切断部９に供給される第一ガラスフィルムＧ１を精度良く切断することができるように、第一ガラスフィルムＧ１の位置を調整する。 The upstream side adjusting device 40 adjusts the position of the first glass film G1 so that the first glass film G1 supplied to the second cutting portion 9 can be cut with high accuracy.
　具体的には、図８に示すように、上流側調整装置４０は、搬送ローラ３４を、第一の軸Ａ１が第一ガラスフィルムＧ１の幅方向Ｙと平行となる基準姿勢（実線で示す姿勢）から、第二の軸Ａ２まわりに所定の角度θ２だけ回動した調整姿勢（二点鎖線で示す姿勢）に変更する。 Specifically, as shown in FIG. 8, the upstream side adjusting device 40 arranges the transport roller 34 in a reference posture (a posture shown by a solid line) in which the first axis A1 is parallel to the width direction Y of the first glass film G1. ) Is changed to an adjustment posture (posture indicated by a two-dot chain line) rotated by a predetermined angle θ2 around the second axis A2.
　上流側調整装置４０による第一ガラスフィルムＧ１の位置調整量（位置調整角度θ２）は、下流側調整装置２４ａ，２４ｂによる第二ガラスフィルムＧ２の位置調整量（位置調整角度θ１）よりも大きく設定されることが望ましい。すなわち、下流側調整装置２４ａ，２４ｂによる位置調整量は、上流側調整装置４０による位置調整量よりも小さく設定されることが望ましい。この構成によれば、上流側調整装置４０によって相対的に大きく第一ガラスフィルムＧ１の位置調整を行うことができ、下流側調整装置２４によって第二ガラスフィルムＧ２の位置の微調整を行うことができる。これにより、第二切断部９に悪影響が及ぶのを防止することができる。 The position adjustment amount (position adjustment angle θ2) of the first glass film G1 by the upstream side adjustment device 40 is set larger than the position adjustment amount (position adjustment angle θ1) of the second glass film G2 by the downstream side adjustment devices 24a and 24b. It is desirable to be done. That is, it is desirable that the position adjustment amount by the downstream side adjusting devices 24a and 24b is set smaller than the position adjustment amount by the upstream side adjusting device 40. According to this configuration, the position of the first glass film G1 can be adjusted relatively largely by the upstream side adjusting device 40, and the position of the second glass film G2 can be finely adjusted by the downstream side adjusting device 24. can. As a result, it is possible to prevent the second cutting portion 9 from being adversely affected.
　第二切断工程Ｓ１６では、各第二レーザ照射装置３０から第二ガラスフィルムＧ２に対してレーザ光Ｌが照射され、各第二冷却装置３１から第二ガラスフィルムＧ２に向かって冷媒Ｒが噴射される。これにより、第一ガラスフィルムＧ１から非製品部Ｇｓが分離され、製品部としての二枚の第二ガラスフィルムＧ２ａ，Ｇ２ｂが形成される。二枚の第二ガラスフィルムＧ２ａ，Ｇ２ｂは、下流側調整装置２４ａ，２４ｂ（下流側調整工程Ｓ１７）を経て、第二巻取装置１０ａ，１０ｂへと搬送される。 In the second cutting step S16, the laser beam L is irradiated from each second laser irradiation device 30 to the second glass film G2, and the refrigerant R is injected from each second cooling device 31 toward the second glass film G2. To. As a result, the non-product portion Gs is separated from the first glass film G1, and two second glass films G2a and G2b as the product portion are formed. The two second glass films G2a and G2b are conveyed to the second winding devices 10a and 10b via the downstream side adjusting devices 24a and 24b (downstream side adjusting step S17).
　第二巻取工程Ｓ１８では、二台の第二巻取装置１０ａ，１０ｂによって二枚の第二ガラスフィルムＧ２ａ，Ｇ２ｂが個別に巻き取られる。これにより、各第二巻取装置１０ａ，１０ｂに第二ガラスロールＧＲＬ２ａ，ＧＲＬ２ｂが形成される。 In the second winding step S18, the two second glass films G2a and G2b are individually wound by the two second winding devices 10a and 10b. As a result, the second glass rolls GRL2a and GRL2b are formed on the second winding devices 10a and 10b.
　本実施形態におけるその他の構成は、第一実施形態と同じである。本実施形態において第一実施形態と共通する構成要素には、共通符号を付している。 Other configurations in this embodiment are the same as those in the first embodiment. The components common to the first embodiment in the present embodiment are designated by a common reference numeral.
　図１０乃至図１３は、本発明の第三実施形態を示す。図１０及び図１１に示すように、本実施形態に係る製造装置１の下流側調整装置２４は、搬送ローラ３４及び駆動機構３５の他、第二ガラスフィルムＧ２の幅方向Ｙにおける端部Ｇａの位置を検出するエッジセンサ４１と、制御装置４２とを備える。 10 to 13 show a third embodiment of the present invention. As shown in FIGS. 10 and 11, the downstream side adjusting device 24 of the manufacturing apparatus 1 according to the present embodiment includes a transfer roller 34 and a drive mechanism 35, as well as an end Ga of the second glass film G2 in the width direction Y. It includes an edge sensor 41 for detecting a position and a control device 42.
　エッジセンサ４１としては、例えばＬＥＤ等を利用する光学式センサが使用されるが、他の非接触式のセンサを使用してもよい。図１０及び図１１に示すように、エッジセンサ４１は、第二ガラスフィルムＧ２の下方に配される投光部４１ａと、投光部４１ａと対向するように、第二ガラスフィルムＧ２の上方に配される受光部４１ｂとを有する。投光部４１ａ及び受光部４１ｂは、平面視において第二ガラスフィルムＧ２の端部Ｇａと重なるように配置されている。 As the edge sensor 41, for example, an optical sensor using an LED or the like is used, but other non-contact type sensors may be used. As shown in FIGS. 10 and 11, the edge sensor 41 is located above the second glass film G2 so as to face the light projecting unit 41a arranged below the second glass film G2 and the light projecting unit 41a. It has a light receiving unit 41b to be arranged. The light emitting portion 41a and the light receiving portion 41b are arranged so as to overlap the end portion Ga of the second glass film G2 in a plan view.
　図１１に示すように、エッジセンサ４１は、投光部４１ａから放射した光ＬＴを受光部４１ｂに受光させる。投光部４１ａから放射された光ＬＴは、第二ガラスフィルムＧ２の端部Ｇａを透過し、受光部４１ｂに到達する。エッジセンサ４１は、受光部４１ｂが検出した光ＬＴの信号に基づいて、第二ガラスフィルムＧ２の端部Ｇａの幅方向Ｙにおける位置を検出することができる。 As shown in FIG. 11, the edge sensor 41 causes the light receiving unit 41b to receive the light LT emitted from the light projecting unit 41a. The light LT emitted from the light projecting unit 41a passes through the end portion Ga of the second glass film G2 and reaches the light receiving unit 41b. The edge sensor 41 can detect the position of the end portion Ga of the second glass film G2 in the width direction Y based on the signal of the optical LT detected by the light receiving portion 41b.
　図１１及び図１２に示すように、駆動機構３５は、軸受３６及びモータ３７を備えるが、本実施形態ではモータ３７の構成が第一実施形態と異なる。本実施形態に係るモータ３７は、リニアモータ（例えばリニアサーボモータ）により構成される。 As shown in FIGS. 11 and 12, the drive mechanism 35 includes a bearing 36 and a motor 37, but in the present embodiment, the configuration of the motor 37 is different from that of the first embodiment. The motor 37 according to this embodiment is composed of a linear motor (for example, a linear servo motor).
　モータ３７は、搬送ローラ３４の各軸端部３４ａ，３４ｂのうち、一方の軸端部３４ａを支持する軸受３６に設けられている。モータ３７は、この軸受３６を所定の方向に移動させる駆動部４３と、この駆動部４３を支持する支持台４４とを備える。なお、本実施形態では、搬送ローラ３４の他方の軸端部３４ｂを支持する軸受３６にモータ３７が設けられていない例を示すが、この軸受３６にモータ３７が設けられてもよい。 The motor 37 is provided on the bearing 36 that supports one of the shaft end portions 34a and 34b of the transport roller 34. The motor 37 includes a drive unit 43 that moves the bearing 36 in a predetermined direction, and a support base 44 that supports the drive unit 43. Although the present embodiment shows an example in which the motor 37 is not provided on the bearing 36 that supports the other shaft end portion 34b of the transport roller 34, the motor 37 may be provided on the bearing 36.
　駆動部４３は、その上面において、搬送ローラ３４の一方の軸端部３４ａに係る軸受３６を支持している。図１１乃至図１３に示すように、駆動部４３は、第一移動方向Ｄ１又は第二移動方向Ｄ２に移動可能に構成されている。 The drive unit 43 supports the bearing 36 related to one of the shaft end portions 34a of the transport roller 34 on the upper surface thereof. As shown in FIGS. 11 to 13, the drive unit 43 is configured to be movable in the first movement direction D1 or the second movement direction D2.
　支持台４４は、駆動部４３をスライド可能に支持するレール部（ガイド部）４５を備える。レール部４５は、第二ガラスフィルムＧ２の横搬送方向Ｘ２に沿うように直線状に構成される。 The support base 44 includes a rail portion (guide portion) 45 that slidably supports the drive portion 43. The rail portion 45 is formed linearly along the lateral transport direction X2 of the second glass film G2.
　下流側調整工程において、モータ３７は、支持台４４のレール部４５に沿って駆動部４３を第一移動方向Ｄ１又は第二移動方向Ｄ２に移動させることで、搬送ローラ３４の一方の軸端部３４ａ及びその軸受３６の位置を変更する。この場合において、搬送ローラ３４は、他方の軸端部３４ｂを支持する軸受３６の位置を中心として回動することで、その姿勢を変更する。 In the downstream adjustment step, the motor 37 moves the drive unit 43 in the first movement direction D1 or the second movement direction D2 along the rail portion 45 of the support base 44, so that one shaft end portion of the transport roller 34 The positions of 34a and its bearing 36 are changed. In this case, the transport roller 34 changes its posture by rotating around the position of the bearing 36 that supports the other shaft end portion 34b.
　制御装置４２は、エッジセンサ４１及びモータ３７に接続されている。制御装置４２は、第二ガラスフィルムＧ２の端部Ｇａが所定の基準位置からずれたときに、エッジセンサ４１によって検出された端部Ｇａの位置情報に基づいて、モータ３７を作動させる。例えば、図１２において、エッジセンサ４１が、第二ガラスフィルムＧ２が左側（第二ガラスフィルムＧ２の端部Ｇｂ側）へ斜行するのを検知した場合、制御装置４２は、モータ３７を作動させ、搬送ローラ３４の軸端部３４ａ及びその軸受３６を第一移動方向Ｄ１に移動させ、搬送ローラ３４は、図１３において実線で示す基準姿勢から、二点鎖線で示す調整姿勢へと姿勢を変更する。逆に、図１２において、エッジセンサ４１が、第二ガラスフィルムＧ２が右側（第二ガラスフィルムＧ２の端部Ｇａ側）へ斜行するのを検知した場合、制御装置４２は、搬送ローラ３４の軸端部３４ａ及びその軸受３６を図１３における第二移動方向Ｄ２に移動させる。 The control device 42 is connected to the edge sensor 41 and the motor 37. The control device 42 operates the motor 37 based on the position information of the end Ga detected by the edge sensor 41 when the end Ga of the second glass film G2 deviates from a predetermined reference position. For example, in FIG. 12, when the edge sensor 41 detects that the second glass film G2 is skewed to the left side (the end portion Gb side of the second glass film G2), the control device 42 operates the motor 37. The shaft end portion 34a of the transport roller 34 and its bearing 36 are moved in the first movement direction D1, and the transport roller 34 changes its posture from the reference posture shown by the solid line in FIG. 13 to the adjustment posture shown by the two-dot chain line. do. On the contrary, in FIG. 12, when the edge sensor 41 detects that the second glass film G2 is skewed to the right side (the end Ga side of the second glass film G2), the control device 42 is the transfer roller 34. The shaft end portion 34a and its bearing 36 are moved in the second moving direction D2 in FIG.
　上記のような搬送ローラ３４の姿勢の調整により、下流側調整装置２４は、第二ガラスフィルムＧ２の蛇行及び斜行を抑制することができる。本実施形態に係る製造装置１は、下流側調整装置２４のエッジセンサ４１及び制御装置４２によって搬送ローラ３４の姿勢を自動的に調整することで、第二ガラスフィルムＧ２を効率良く製造することができる。 By adjusting the posture of the transport roller 34 as described above, the downstream side adjusting device 24 can suppress meandering and skewing of the second glass film G2. The manufacturing apparatus 1 according to the present embodiment can efficiently manufacture the second glass film G2 by automatically adjusting the posture of the transport roller 34 by the edge sensor 41 and the control device 42 of the downstream side adjusting device 24. can.
