Description

本発明は、太陽電池のタブ線接合用等の一連の長尺の接着フィルムを巻き取り且つ引き出すためのリール部材の技術に関する。   The present invention relates to a reel member technique for winding up and pulling out a series of long adhesive films for tab line bonding of solar cells.

従来より、種々の電子部品等を接着するための長尺の接着フィルムが知られている。
このような接着フィルムは、幅狭で長尺の剥離シート上に形成され、リール部材にロール状に巻取った形態で出荷されている。 Conventionally, long adhesive films for bonding various electronic components and the like are known.
Such an adhesive film is formed on a narrow and long release sheet, and is shipped in the form of a reel member wound up in a roll shape.

ところで、近年、このような接着フィルムの長尺化が望まれているが、接着フィルムが長尺化すると、フィルムロールの径が増すことによって接着フィルムに生じる応力が特に巻芯部において増大するため、接着フィルム内の接着剤がはみ出てフランジ部に付着するおそれがあるという問題がある。   By the way, in recent years, it has been desired to lengthen such an adhesive film. However, when the length of the adhesive film is increased, the stress generated in the adhesive film increases due to an increase in the diameter of the film roll, particularly in the core portion. There is a problem that the adhesive in the adhesive film may protrude and adhere to the flange portion.

このような問題に対しては、リール部材の巻芯軸部を幅広に形成し、接着フィルムを所謂トラバース巻きにすることによって上述した問題を解決することができる可能性がある。
しかし、トラバース巻きで接着フィルムを巻き付けた場合には、巻芯軸部に巻き付けた接着フィルムの応力によって巻芯軸部に大きな力が作用し、巻芯軸部に歪みが生じて引出装置の駆動軸に装着することができなくなるという問題がある。 In order to solve such a problem, there is a possibility that the above-mentioned problem can be solved by forming the core shaft portion of the reel member wide and making the adhesive film so-called traverse winding.
However, when the adhesive film is wound by traverse winding, a large force acts on the core shaft portion due to the stress of the adhesive film wound around the core shaft portion, and the core shaft portion is distorted to drive the drawing device. There is a problem that the shaft cannot be mounted.

これに対し、巻芯軸部を鉄やＳＵＳ等の硬質の材料を用いることにより巻芯軸部の歪みを防止することも考えられるが、その場合には、リール部材の重量が大きくなるため、リール設置装置の剛性を大きくする必要性があるとともに、接着フィルムの巻取及び引出時に大きな力が必要になるという問題がある。
なお、本発明に関連する先行技術文献としては、例えば以下に示すようなものがある。 On the other hand, it is conceivable to prevent distortion of the core shaft portion by using a hard material such as iron or SUS for the core shaft portion, but in that case, the weight of the reel member increases. There is a need to increase the rigidity of the reel installation device, and there is a problem that a large force is required when winding and pulling out the adhesive film.
In addition, as a prior art document relevant to this invention, there exist the following, for example.

特開２０１１−１１７９２号公報JP 2011-11792 A

本発明は、このような従来の技術の課題を考慮してなされたもので、その目的とするところは、非常に長尺の接着フィルムをリール部材に巻き付けて円滑に引き出すことができる技術を提供することにある。   The present invention has been made in consideration of the above-described problems of the conventional technology, and an object of the present invention is to provide a technology that allows a very long adhesive film to be wound around a reel member and smoothly drawn out. There is to do.

上記目的を達成するためになされた本発明は、円筒形状に形成され、接着フィルムを巻取可能な巻芯軸部と、前記巻芯軸部の両端部に設けられた第１及び第２フランジ部と、前記巻芯軸部内において前記巻芯軸部と同心状に配置され、前記第１及び第２フランジ部に固定された円筒形状の駆動軸支持部を有する軸芯部とを備えたリール部材である。
本発明では、巻芯軸部の直径が、５０〜１２０ｍｍである場合にも効果的である。
本発明では、巻芯軸部の幅が、２０〜１００ｍｍである場合にも効果的である。
本発明では、第１及び第２フランジ部の厚さが、１．５〜５ｍｍである場合にも効果的である。
本発明では、軸芯部の駆動軸支持部の径が、１８．０〜２６．０ｍｍである場合にも効果的である。
また、本発明は、上述したリール部材と、当該リール部材の巻芯軸部にトラバース巻きで巻き付けられた接着フィルムとを有するフィルム収容体である。
一方、本発明は、上述したいずれかのフィルム収容体を製造する方法であって、上述したリール部材を巻取駆動軸に装着し、フィルム供給源から供給された接着フィルムの先端部を前記巻芯軸部に取り付け、前記巻取駆動軸と平行な回転軸を有する弾性の押圧ローラによって前記接着フィルムを前記リール部材の巻芯軸部に押圧した状態で、前記巻取駆動軸を巻取方向に回転させるとともに、ガイドによって当該接着フィルムを当該巻取駆動軸方向に案内することにより、当該リール部材の巻芯軸部に当該接着フィルムをトラバース巻きで前記押圧ローラの幅と同等の幅に巻き付ける工程を有するフィルム収容体の製造方法である。 The present invention made to achieve the above object includes a core shaft portion formed in a cylindrical shape and capable of winding an adhesive film, and first and second flanges provided at both ends of the core shaft portion. And a shaft core portion disposed concentrically with the core shaft portion in the core shaft portion and having a cylindrical drive shaft support portion fixed to the first and second flange portions. It is a member.
The present invention is also effective when the diameter of the core shaft portion is 50 to 120 mm.
In this invention, it is effective also when the width | variety of a core axis part is 20-100 mm.
In this invention, it is effective also when the thickness of a 1st and 2nd flange part is 1.5-5 mm.
In this invention, it is effective also when the diameter of the drive shaft support part of an axial center part is 18.0-26.0 mm.
Moreover, this invention is a film container which has the reel member mentioned above and the adhesive film wound by the traverse winding to the core shaft part of the said reel member.
On the other hand, the present invention is a method for manufacturing any of the above-described film containers, wherein the reel member described above is mounted on a take-up drive shaft, and the leading end portion of an adhesive film supplied from a film supply source is wound on the winding. The winding drive shaft is wound in the winding direction in a state where the adhesive film is pressed against the core shaft portion of the reel member by an elastic pressing roller attached to the core shaft portion and having a rotation shaft parallel to the winding drive shaft. The adhesive film is guided by the guide in the winding drive shaft direction, and the adhesive film is wound around the core shaft portion of the reel member by traverse winding to a width equivalent to the width of the pressing roller. It is a manufacturing method of the film container which has a process.

本発明のリール部材及びフィルム収容体の場合、駆動軸支持部を有する軸芯部が巻芯軸部内の空間において第１及び第２のフランジ部に固定されていることから、巻芯軸部に接着フィルムを巻き付け接着フィルムの応力によって巻芯軸部に大きな力が作用した場合であっても軸芯部には歪みが生ずることはない。
その結果、本発明によれば、例えば接着フィルムをトラバース巻きによって巻き付けたリール部材（フィルム収容体）を引出装置の駆動軸に装着する場合に問題なく装着を行うことができるので、非常に長尺の接着フィルムが巻き付けられたフィルム収容体を提供することができる。
また、本発明によれば、リール部材を構成する各部分は樹脂の成形によって作成することができるため、鉄やＳＵＳ等の硬質の材料を用いた場合と比べて重量が小さく、その結果、リール設置装置の剛性を大きくする必要はなく、また接着フィルムの巻取及び引出時に大きな力が必要になることもない。
一方、通常のトラバース巻きの場合、ロールの端部においてフィルム等の脱落（巻き崩れ）が生ずるおそれがあることから、ロールの上層に行くに従って巻き幅が狭くならざるを得ないが、本発明の方法の場合、弾性の押圧ローラによって接着フィルムをリール部材の巻芯軸部に押圧した状態で、巻取駆動軸を巻取方向に回転させるとともに、ガイドによって接着フィルムを巻取駆動軸方向に案内することにより、リール部材の巻芯軸部に接着フィルムをトラバース巻きで押圧ローラの幅と同等の幅に巻き付けることから、ロールの両端部において接着フィルムの脱落が発生せず、巻き数を最大にすることができるので、リール部材に巻き付けられる接着フィルムの一層の長尺化を図ることができる。 In the case of the reel member and the film container of the present invention, the shaft core portion having the drive shaft support portion is fixed to the first and second flange portions in the space in the core shaft portion. Even when the adhesive film is wound and a large force is applied to the core shaft portion due to the stress of the adhesive film, the shaft core portion is not distorted.
As a result, according to the present invention, for example, when a reel member (film container) around which an adhesive film is wound by traverse winding is mounted on the drive shaft of the drawing device, it can be mounted without any problem. It is possible to provide a film container in which the adhesive film is wound.
In addition, according to the present invention, each part constituting the reel member can be formed by resin molding, so that the weight is small compared to the case of using a hard material such as iron or SUS. As a result, the reel There is no need to increase the rigidity of the installation device, and no great force is required when winding and pulling out the adhesive film.
On the other hand, in the case of normal traverse winding, there is a possibility that a film or the like may fall off (rolling) at the end of the roll, so the winding width must be narrowed as it goes to the upper layer of the roll. In the case of the method, the winding driving shaft is rotated in the winding direction while the adhesive film is pressed against the core shaft portion of the reel member by the elastic pressing roller, and the adhesive film is guided in the winding driving shaft direction by the guide. As a result, the adhesive film is wound around the core shaft portion of the reel member by traverse winding to a width equivalent to the width of the pressing roller, so that the adhesive film does not fall off at both ends of the roll, and the number of windings is maximized. Therefore, it is possible to further increase the length of the adhesive film wound around the reel member.

本発明によれば、非常に長尺の接着フィルムを巻き付けて円滑に引き出すことができるフィルム収容体を提供することができる。
その結果、本発明によれば、接着フィルムの貼付工程において、リール部材を頻繁に交換する必要がなく、生産効率を大幅に向上させることができる。 ADVANTAGE OF THE INVENTION According to this invention, the film container which can wind out a very long adhesive film and can be drawn out smoothly can be provided.
As a result, according to the present invention, it is not necessary to frequently replace the reel member in the adhesive film sticking step, and the production efficiency can be greatly improved.

この場合、隣接する接着フィルム１０の間隔ｐは、特に限定されることはないが、０．０５〜０．１ｍｍとなるように設定することが好ましい。   In this case, the interval p between the adjacent adhesive films 10 is not particularly limited, but is preferably set to be 0.05 to 0.1 mm.

隣接する接着フィルム１０の間隔ｐが０．０５ｍｍより小さいと、フィルム幅方向にはみ出す接着剤によって隣接する接着フィルム１０同士が接着するおそれがあり、他方、０．１ｍｍより大きいと、接着フィルム１０を巻き取る際に巻き崩れが発生するおそれがあり、２層タイプの場合は隣接する接着フィルム１０の隙間から上下層の接着フィルム１０が接触しブロッキングが発生するおそれがある。   If the distance p between the adjacent adhesive films 10 is smaller than 0.05 mm, the adjacent adhesive films 10 may be bonded to each other by the adhesive protruding in the film width direction. When winding, there is a possibility that collapse may occur, and in the case of a two-layer type, there is a possibility that the upper and lower adhesive films 10 come into contact with each other from the gap between adjacent adhesive films 10 and blocking occurs.

図６及び図７（ａ）（ｂ）は、本発明のフィルム収容体の製造方法の例を示すものである。
上述したフィルム収容体７を製造するには、例えば図６に示すフィルム巻取装置を用いるとよい。 FIG.6 and FIG.7 (a) (b) shows the example of the manufacturing method of the film container of this invention.
In order to manufacture the film container 7 described above, for example, a film winding device shown in FIG. 6 may be used.

このフィルム巻取装置は、巻取駆動軸２４を有し、この巻取駆動軸２４に上述したリール部材１を装着するように構成されている。
この巻取駆動軸２４の近傍には、例えばシリコーンゴム等の弾性材料からなりリール部材１の巻芯軸部２に対して所定の力で押圧可能な押圧ローラ２３が設けられている。 This film winding device has a winding drive shaft 24 and is configured to mount the reel member 1 described above on the winding drive shaft 24.
In the vicinity of the winding drive shaft 24, a pressing roller 23 made of an elastic material such as silicone rubber, for example, can be pressed against the core shaft portion 2 of the reel member 1 with a predetermined force.

この押圧ローラ２３は、上記巻取駆動軸２４と平行に設けた回転軸２２に取り付けられている。そして、図示しない駆動機構によって巻取駆動軸２４又は回転軸２２を回転駆動させ、巻取駆動軸２４に装着されたリール部材１の巻芯軸部２に巻き取られる接着フィルム１０の摩擦力によって巻取駆動軸２４と回転軸２２が共に駆動されるように構成されている。   The pressing roller 23 is attached to a rotating shaft 22 provided in parallel with the winding drive shaft 24. Then, the winding drive shaft 24 or the rotary shaft 22 is rotationally driven by a drive mechanism (not shown), and the frictional force of the adhesive film 10 wound around the core shaft portion 2 of the reel member 1 mounted on the winding drive shaft 24 is used. The take-up drive shaft 24 and the rotary shaft 22 are both driven.

この場合、押圧ローラ２３の幅は、リール部材１の巻芯軸部２の幅Ｗ（図３参照）より小さく、接着フィルム１０の脱落を防止する観点から、接着フィルム１０のロール幅ｗと同等（同一若しくは０〜−１．０ｍｍ）に設定することが好ましい。   In this case, the width of the pressing roller 23 is smaller than the width W (see FIG. 3) of the core shaft portion 2 of the reel member 1 and is equivalent to the roll width w of the adhesive film 10 from the viewpoint of preventing the adhesive film 10 from falling off. It is preferable to set (same or 0 to -1.0 mm).

さらに、押圧ローラ２３の近傍には、その表面にガイド溝２１ａ（図７（ａ）（ｂ）参照）を有するガイドローラ２１が設けられ、このガイドローラ２１は、上記巻取駆動軸２４と平行に設けられその軸方向に移動可能なガイドローラ駆動軸２０によって駆動されるように構成されている。   Further, a guide roller 21 having a guide groove 21 a (see FIGS. 7A and 7B) on its surface is provided in the vicinity of the pressing roller 23, and this guide roller 21 is parallel to the winding drive shaft 24. It is comprised so that it may drive by the guide roller drive shaft 20 which is provided in this and can move to the axial direction.

このフィルム巻取装置を用いてリール部材１に接着フィルム１０を巻き取る場合には、図示しないフィルム供給源から引き出された接着フィルム１０をガイドローラ２１のガイド溝２１ａを介して押圧ローラ２３に引き渡し、リール部材１の巻芯軸部２と押圧ローラ２３の間を通してたすき掛けにし巻芯軸部２の一方の端部に接着フィルム１０の先端部を取り付る。
この状態で、巻取駆動軸２４又は回転軸２２を巻取方向に回転させる。 When the adhesive film 10 is wound around the reel member 1 using this film winding device, the adhesive film 10 drawn from a film supply source (not shown) is delivered to the pressing roller 23 via the guide groove 21a of the guide roller 21. The tip of the adhesive film 10 is attached to one end of the core shaft 2 by passing between the core shaft 2 of the reel member 1 and the pressing roller 23.
In this state, the winding drive shaft 24 or the rotating shaft 22 is rotated in the winding direction.

この場合、図７（ａ）（ｂ）に示すように、押圧ローラ２３によって接着フィルム１０をリール部材１の巻芯軸部２に押圧しつつ、ガイドローラ駆動軸２０をその軸方向に移動させ、接着フィルム１０を巻取駆動軸２４方向に巻芯軸部２の一方の端部から他方の端部に移動させる。
そして、この動作を繰り返すことにより、リール部材１の巻芯軸部２上に接着フィルム１０をトラバース巻きによって巻き取る。
なお、本実施の形態では、接着フィルム１０のロールの両端部において一層おきに接着フィルム１０同士が重なるようにガイドローラ駆動軸２０の動作を制御する。 In this case, as shown in FIGS. 7A and 7B, the guide roller driving shaft 20 is moved in the axial direction while pressing the adhesive film 10 against the core shaft portion 2 of the reel member 1 by the pressing roller 23. Then, the adhesive film 10 is moved in the direction of the winding drive shaft 24 from one end portion of the core shaft portion 2 to the other end portion.
Then, by repeating this operation, the adhesive film 10 is wound on the core shaft portion 2 of the reel member 1 by traverse winding.
In the present embodiment, the operation of the guide roller drive shaft 20 is controlled so that the adhesive films 10 overlap each other at both ends of the roll of the adhesive film 10.

以上述べた本実施の形態のリール部材１及びフィルム収容体７の場合、駆動軸支持部４ａを有する軸芯部４が巻芯軸部２内の内部３において第１及び第２のフランジ部１１，１２に固定されていることから、巻芯軸部２に接着フィルム１０を巻き付け接着フィルム１０の応力によって巻芯軸部２に大きな力が作用した場合であっても軸芯部４には歪みが生ずることはない。   In the case of the reel member 1 and the film container 7 according to the present embodiment described above, the shaft core portion 4 having the drive shaft support portion 4 a is provided in the inner portion 3 in the core shaft portion 2, and the first and second flange portions 11. Therefore, even if a large force is applied to the core shaft portion 2 due to the stress of the adhesive film 10, the shaft core portion 4 is distorted. Will not occur.

その結果、本実施の形態によれば、接着フィルム１０をトラバース巻きによって巻き付けたリール部材１を引出装置の駆動軸に装着する場合に問題なく装着を行うことができるので、非常に長尺の接着フィルム１０が巻き付けられたフィルム収容体７を提供することができる。   As a result, according to this embodiment, when the reel member 1 around which the adhesive film 10 is wound by traverse winding is mounted on the drive shaft of the drawing device, it can be mounted without any problem. The film container 7 around which the film 10 is wound can be provided.

また、本実施の形態によれば、リール部材１を構成する各部分は樹脂の成形によって作成することができるため、鉄やＳＵＳ等の硬質の材料を用いた場合と比べて重量が小さく、その結果、リール設置装置の剛性を大きくする必要はなく、また接着フィルム１０の巻取及び引出時に大きな力が必要になることもない。   In addition, according to the present embodiment, each part constituting the reel member 1 can be formed by resin molding, so that the weight is small compared to the case where a hard material such as iron or SUS is used. As a result, it is not necessary to increase the rigidity of the reel installation device, and a large force is not required when the adhesive film 10 is wound and pulled out.

一方、通常のトラバース巻きの場合、フィルム等のロールの端部において脱落（巻き崩れ）が生ずるおそれがあることから、ロールの上層に行くに従って巻き幅が狭くならざるを得ないが、本実施の形態の方法の場合、弾性の押圧ローラ２３によって接着フィルム１０をリール部材１の巻芯軸部２に押圧した状態で、巻取駆動軸２４を巻取方向に回転させるとともに、ガイドローラ２１によって接着フィルム１０を巻取駆動軸２４の方向に案内することにより、リール部材１の巻芯軸部２にトラバース巻きで接着フィルム１０を押圧ローラ２３の幅と同等の幅に巻き付けることから、接着フィルム１０のロールの両端部において接着フィルム１０の脱落が発生せず、巻き数を最大にすることができるので、リール部材１に巻き付けられる接着フィルム１０の一層の長尺化を図ることができる。   On the other hand, in the case of normal traverse winding, there is a risk of falling off (rolling) at the end of a roll of film or the like, so the winding width must be narrowed toward the upper layer of the roll. In the case of the embodiment method, the winding drive shaft 24 is rotated in the winding direction while the adhesive film 10 is pressed against the core shaft portion 2 of the reel member 1 by the elastic pressing roller 23 and is bonded by the guide roller 21. By guiding the film 10 in the direction of the take-up drive shaft 24, the adhesive film 10 is wound around the core shaft portion 2 of the reel member 1 by traverse winding to a width equivalent to the width of the pressing roller 23. Since the adhesive film 10 does not fall off at both ends of the roll, and the number of windings can be maximized, the adhesive wound around the reel member 1 It is possible to further elongation of Irumu 10.

このように、本実施の形態によれば、非常に長尺の接着フィルム１０を巻き付けて円滑に引き出すことができるフィルム収容体７を提供することができ、接着フィルム１０の貼付工程において、リール部材１を頻繁に交換する必要がなく、生産効率を大幅に向上させることができる。   As described above, according to the present embodiment, it is possible to provide the film container 7 that can be smoothly drawn out by winding the very long adhesive film 10, and in the attaching process of the adhesive film 10, the reel member It is not necessary to frequently replace 1 and production efficiency can be greatly improved.

なお、本発明は上述の実施の形態に限られることはなく、種々の変更を行うことができる。
例えば、上述した実施の形態においては、リール部材１の軸芯部４を一体構成の円筒形状としたが、本発明はこれに限られず、第１及び第２のフランジ部１１，１２においてそれぞれ別個の軸芯部を設けることもできる。 The present invention is not limited to the above-described embodiment, and various changes can be made.
For example, in the above-described embodiment, the axial core portion 4 of the reel member 1 is formed as an integral cylindrical shape. However, the present invention is not limited to this, and the first and second flange portions 11 and 12 are separately provided. An axial core part can also be provided.

また、接着フィルム１０の長さ及び第１及び第２のフランジ部１１，１２の厚さによっては、第１及び第２のフランジ部１１，１２に設けた孔部５，６の内壁によって駆動軸支持部を構成することもできる。   Further, depending on the length of the adhesive film 10 and the thickness of the first and second flange portions 11 and 12, the drive shaft is formed by the inner walls of the holes 5 and 6 provided in the first and second flange portions 11 and 12. A support part can also be comprised.

＜評価結果＞
表１から明らかなように、巻芯軸部を設けない構成の比較例１の場合、接着フィルムの巻き長さが３００ｍ、５００ｍと短い場合には、フィルム引出時において問題は生じなかったが、接着フィルムの長さが２０００ｍ、５０００ｍと長尺化した場合には、軸芯部の歪みによってフィルム引出装置の駆動軸にリール部材を装着することができなかった。 <Evaluation results>
As is clear from Table 1, in the case of Comparative Example 1 in which the core shaft portion is not provided, when the winding length of the adhesive film is as short as 300 m and 500 m, no problem occurred at the time of drawing the film. When the length of the adhesive film was increased to 2000 m and 5000 m, the reel member could not be mounted on the drive shaft of the film drawing device due to distortion of the shaft core portion.

一方、従来の構成のリール部材を用いた比較例２の場合、接着フィルムの巻き長さが３００ｍ、５００ｍと短い場合には、フィルム引出時において問題は生じなかったが、接着フィルムの巻き長さが２０００ｍ、５０００ｍと長尺化した場合にブロッキング及び接着剤のはみ出しが生じ、フィルム収容体を形成することができなかった。   On the other hand, in the case of the comparative example 2 using the reel member having the conventional configuration, when the winding length of the adhesive film is as short as 300 m and 500 m, no problem occurred when the film was drawn, but the winding length of the adhesive film However, when the length of the film was increased to 2000 m and 5000 m, blocking and protrusion of the adhesive occurred, and the film container could not be formed.
