Abstract

The disclosed reel (1) is provided with a winding core (2) and a pair of side plates (3). An adhesive tape (T) is wound around the winding core (2). The pair of side plates (3) are affixed to the ends of the winding core (2). Radial ribs (6) are formed on the inside surface (3a) of each side plate (3). The ribs (6) on one side plate (3) are offset from the ribs (6) on the other side plate (3) by an angle θ. The tape (T) wound around the winding core (2) contacts the ribs (6). The ribs (6) on both sides, offset from each other, can cause the tape (T) to form an S-shaped curve. The separation (W1) between the pair of side plates (3) can be less than the separation (W2) between conventional pairs of side plates (3). The tape (T) may be an anisotropic conductive tape. Anisotropic conductive tape comprises a substrate and an anisotropic conductive film formed on the substrate. The offset of angle θ between the ribs (6) on both sides inhibits separation (blocking) of the anisotropic conductive film from the substrate.

　ところで、異方導電テープのような接着テープが巻き付けられるリールは、一般に、巻芯と、巻き崩れを防止するための一対の側板とを備えている。従来、接着テープをリールに巻き付ける工程では、リールの側板にテープの接着剤層や基材が接触したり、保存時に接着剤層が滲み出したりすると、基材からの接着剤層の剥がれ（ブロッキング現象）が生じることがあった。 By the way, a reel on which an adhesive tape such as an anisotropic conductive tape is wound generally comprises a core and a pair of side plates for preventing the winding collapse. Conventionally, in the step of winding the adhesive tape around the reel, if the adhesive layer or base material of the tape comes into contact with the side plate of the reel or the adhesive layer exudes during storage, peeling of the adhesive layer from the base (blocking Phenomenon may occur.
　これに対し、特許文献２に記載のリールでは、側板の中心側から周縁側にかけて延在する複数のリブが側板の内側面に設けられている。これにより、接着テープの側部と側板との直接的な接触が回避され、ブロッキング現象の防止が図られている。そこで、このようなリールでは、ブロッキング現象を防止できる利点をより生すための構成上の一層の工夫が望まれている。 On the other hand, in the reel described in Patent Document 2, a plurality of ribs extending from the center side to the peripheral side of the side plate are provided on the inner side surface of the side plate. As a result, direct contact between the side of the adhesive tape and the side plate is avoided, and the blocking phenomenon is prevented. Therefore, with such a reel, it is desired to further devise a configuration in order to obtain the advantage of preventing the blocking phenomenon.
　本発明は、上記課題の解決のためになされたものであり、ブロッキング現象を防止できる接着テープ用リールを提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a reel for adhesive tape which can prevent the blocking phenomenon.
　上記課題の解決のため、本発明に係る接着テープ用リールは、接着テープを巻き付け可能な筒状の巻芯と、巻芯の両端部に互いに対向して設けられている一対の側板と、を備え、側板の内側面には、当該側板の中心側から周縁側にかけて延在する複数のリブが形成され、一対の側板は、一方の側板におけるリブの位置と他方の側板におけるリブの位置とがずれた状態で巻芯に固定されていることを特徴としている。 In order to solve the above problems, the reel for adhesive tape according to the present invention comprises a cylindrical core capable of winding the adhesive tape, and a pair of side plates provided opposite to each other at both ends of the core. A plurality of ribs extending from the center side to the peripheral side of the side plate are formed on the inner side surface of the side plate, and the pair of side plates has the position of the rib in one side plate and the position of the rib in the other side plate It is characterized in that it is fixed to the core in a shifted state.
　この接着テープ用リールでは、一対の側板の内側面に当該側板の中心側から周縁側にかけて延在する複数のリブが形成されている。したがって、巻芯に巻き付けられた接着テープはリブに点接触することとなり、テープの側部と側板の内側面との直接的な接触を回避できる。また、この接着テープ用リールでは、一方の側板におけるリブの位置と他方の側板におけるリブの位置とがずれた状態となっている。このため、リブに挟まれた接着テープに過剰な力が加わることも抑制され、ブロッキング現象が発生するきっかけが生じにくくなっている。 In this adhesive tape reel, a plurality of ribs extending from the center side to the peripheral side of the side plates are formed on the inner side surfaces of the pair of side plates. Therefore, the adhesive tape wound around the core is in point contact with the rib, and direct contact between the side of the tape and the inner surface of the side plate can be avoided. Further, in this adhesive tape reel, the position of the rib in one side plate is shifted from the position of the rib in the other side plate. For this reason, it is also suppressed that an excessive force is added to the adhesive tape pinched | interposed into the rib, and the trigger which a blocking phenomenon generate | occur | produces becomes difficult to produce.
　一方、この接着テープ用リールでは、一方の側板におけるリブの位置と他方の側板におけるリブの位置とがずれた状態となっていることで、リブの位置が一致している場合に比べて側板間の距離を小さくできる。これにより、巻き付け作業時に接着テープが側板によって精度良くガイドされるので、作業効率の向上が図られる。また、保存時や運搬時に接着テープに力が加わったとしても、接着テープへのダメージを低減できる。 On the other hand, in this adhesive tape reel, the position of the rib in one side plate and the position of the rib in the other side plate are shifted, so that the distance between the side plates is higher than when the positions of the ribs coincide. Distance can be reduced. As a result, since the adhesive tape is accurately guided by the side plate at the time of the winding operation, the working efficiency can be improved. In addition, even if force is applied to the adhesive tape during storage or transport, damage to the adhesive tape can be reduced.
　また、一方の側板におけるリブと他方の側板におけるリブとのずれ角が５°～１５°であることが好ましい。このようなずれ角を選択することにより、リブに挟まれた接着テープに過剰な力が加わることを好適に抑制でき、ブロッキング現象の発生を一層効果的に防止できる。 Further, it is preferable that the shift angle between the rib in one side plate and the rib in the other side plate is 5 ° to 15 °. By selecting such a shift angle, it is possible to preferably suppress the application of an excessive force to the adhesive tape sandwiched by the ribs, and it is possible to more effectively prevent the occurrence of the blocking phenomenon.
　また、巻芯に巻き付けられる接着テープの長さが３００ｍ以上であることが好ましい。長さが３００ｍ以上の長尺テープでは、巻き取り時に巻重体の側面にうねりが発生し易く、テープの側部と側板の内側面との直接的な接触が発生し易い。したがって、上述したように、一方の側板におけるリブの位置と他方の側板におけるリブの位置とがずれた状態となっていることで、長尺テープに対してもブロッキング現象の発生を効果的に防止できる。また、長尺テープでは、巻芯への巻数が増加するため、巻き付け作業の効率向上による製造コストの低減効果も顕著に得られる。 Moreover, it is preferable that the length of the adhesive tape wound around a core is 300 m or more. In the case of a long tape having a length of 300 m or more, waviness is likely to occur on the side of the winding body during winding, and direct contact between the side of the tape and the inner side of the side plate is likely to occur. Therefore, as described above, the position of the rib in one side plate and the position of the rib in the other side plate are shifted, effectively preventing the occurrence of the blocking phenomenon even for a long tape. it can. Further, in the case of a long tape, since the number of turns around the winding core increases, the effect of reducing the manufacturing cost due to the improvement of the efficiency of the winding operation can be significantly obtained.
　また、巻芯に巻き付けられる接着テープの幅が０．５ｍｍ～３．０ｍｍであることが好ましい。幅が０．５ｍｍ～３．０ｍｍの幅細テープでは、巻芯に巻き付けを行う際、テープが側板と巻重体との間に入り込み易い。したがって、上述したように、巻き付け作業時に接着テープが側板によって精度良くガイドされることで、作業効率の向上が図られる。 Further, the width of the adhesive tape wound around the core is preferably 0.5 mm to 3.0 mm. In the case of a narrow tape having a width of 0.5 mm to 3.0 mm, the tape can easily enter between the side plate and the winding body when winding around a core. Therefore, as described above, when the adhesive tape is accurately guided by the side plate during the winding operation, the working efficiency can be improved.
　また、接着テープは、太陽電池セルの電極とタブ線とを接続する導電テープであることが好ましい。この場合、導電接着テープにおいて、ブロッキング現象を防止できる。 Moreover, it is preferable that an adhesive tape is a conductive tape which connects the electrode and tab wire of a photovoltaic cell. In this case, a blocking phenomenon can be prevented in the conductive adhesive tape.
　本発明に係る接着テープ用リールよれば、巻芯に巻き付けられる接着テープのブロッキング現象を防止できる。 According to the reel for adhesive tape according to the present invention, the blocking phenomenon of the adhesive tape wound around the core can be prevented.

　以下、図面を参照しながら、本発明に係る接着テープ用リールの好適な実施形態について詳細に説明する。 Hereinafter, preferred embodiments of the adhesive tape reel according to the present invention will be described in detail with reference to the drawings.
　図１は、本発明に係る接着テープ用リールの一実施形態を示す正面図である。また、図２は、図１におけるＩＩ－ＩＩ線断面図である。なお、本実施形態における接着テープ用リールは、図１及び図２に示すように、異方導電テープ（接着テープ）Ｔが巻き付けられる筒状の巻芯２と、巻芯２の両端部において巻芯２を挟むように互いに対向して設けられた一対の側板３，３とを備えた接着テープ用リール１として説明する。接着テープ用リール１は、異方導電テープＴを製造・供給・保存する際に用いられる。 FIG. 1 is a front view showing an embodiment of an adhesive tape reel according to the present invention. 2 is a cross-sectional view taken along line II-II in FIG. Incidentally, as shown in FIGS. 1 and 2, the reel for adhesive tape in the present embodiment is wound at the cylindrical core 2 on which the anisotropic conductive tape (adhesive tape) T is wound, and at both ends of the core 2. The adhesive tape reel 1 will be described as provided with a pair of side plates 3 and 3 provided so as to face each other so as to sandwich the core 2. The adhesive tape reel 1 is used when manufacturing, supplying and storing the anisotropic conductive tape T.
　巻芯２には、例えばフィルム状の基材及びその一方面上に設けられた接着剤層を有する異方導電フィルムを細幅のテープ状に切断してなる異方導電テープＴが巻き付けられる。巻芯２の軸方向の長さは、異方導電テープＴの幅に応じて適宜設定されている。また、巻芯２の中央部には、巻付装置又は繰出装置（不図示）の回転軸が挿入される軸穴４が設けられている。軸穴４は例えば断面円形状をなしており、巻付装置又は繰出装置の回転軸を軸穴４に差し込んだ状態で回転軸を駆動した場合に、空回りすることなく接着テープ用リール１が回転するようになっている。 For example, an anisotropic conductive tape T formed by cutting an anisotropic conductive film having a film-like substrate and an adhesive layer provided on one surface thereof into a narrow tape shape is wound around the winding core 2. The axial length of the winding core 2 is appropriately set in accordance with the width of the anisotropic conductive tape T. Further, at the central portion of the winding core 2, there is provided a shaft hole 4 into which a rotation shaft of a winding device or a feeding device (not shown) is inserted. The shaft hole 4 has, for example, a circular cross-sectional shape, and when the rotation shaft is driven with the rotation shaft of the winding device or the feeding device inserted in the shaft hole 4, the adhesive tape reel 1 rotates without idling. It is supposed to
　側板３は、例えば巻芯２に対して十分に大きな径を有する円板状をなしている。巻芯２を介して隔てられた側板３，３間の距離は、異方導電テープＴの幅に応じて適宜設定されている。側板３の厚さは、０．５ｍｍ～５．０ｍｍ、好ましくは０．９ｍｍ～３．０ｍｍ、より好ましくは１．０ｍｍ～２．０ｍｍ程度となっている。また、側板３の径は、巻き付ける異方導電テープＴの長さ（異方導電テープＴの巻重体の直径）に応じて適宜設定される。なお、側板３，３間の距離は、側板３の周縁側ほど広がる傾向にあるので、ここでいう側板３，３間の距離は、巻芯付近での測定値で定義している。通常、側板３，３間の距離は、異方導電テープＴの幅に対して１０５％～１２０％、より好ましくは１０７～１１５％の幅で設定される。 The side plate 3 has, for example, a disk shape having a sufficiently large diameter with respect to the winding core 2. The distance between the side plates 3 separated by the winding core 2 is appropriately set according to the width of the anisotropic conductive tape T. The thickness of the side plate 3 is about 0.5 mm to 5.0 mm, preferably about 0.9 mm to 3.0 mm, and more preferably about 1.0 mm to 2.0 mm. Moreover, the diameter of the side plate 3 is suitably set according to the length (diameter of the winding body of the anisotropically conductive tape T) of the anisotropically conductive tape T to wind. In addition, since the distance between the side plates 3 and 3 tends to spread toward the periphery of the side plate 3, the distance between the side plates 3 and 3 here is defined by the measurement value near the winding core. Usually, the distance between the side plates 3 and 3 is set to a width of 105% to 120%, more preferably 107 to 115% with respect to the width of the anisotropic conductive tape T.
　このような接着テープ用リール１は、射出成形などによって巻芯２及び一対の側板３，３を一体的に成形してもよく、巻芯２及び一対の側板３，３を別々に成形し、これらを嵌合・接着することによって形成してもよい。巻芯２と側板３とを別体とした場合、巻き付ける異方導電テープＴの長さに適した直径の側板３を適宜採用したり、異方導電テープＴの幅に適した長さの巻芯２を適宜採用したりすることができるという利点がある。 Such an adhesive tape reel 1 may be formed integrally with the core 2 and the pair of side plates 3 by injection molding, or the core 2 and the pair of side plates 3 may be separately formed, You may form by fitting and adhere | attaching these. When the winding core 2 and the side plate 3 are separated, the side plate 3 having a diameter suitable for the length of the anisotropic conductive tape T to be wound is suitably adopted, or the length suitable for the width of the anisotropic conductive tape T There is an advantage that the core 2 can be adopted appropriately.
　巻芯２に巻き付けられる異方導電テープＴは、例えば、相対する電極同士の導通状態を保ち、かつ隣接する電極同士の絶縁を保つように、電気的接続と機械的固着とを行う接続材料として使用される。異方導電テープＴの長さは、通常は５０ｍ～１０００ｍ程度であり、本実施形態では３００ｍ以上となっている。異方導電テープＴの長さは、２００ｍ～１０００ｍが好ましく、２５０ｍ～５００ｍがより好ましい。また、異方導電テープＴの幅は、０．５ｍｍ～１０ｍｍ、好ましくは０．５ｍｍ～３．０ｍｍ、より好ましくは０．５ｍｍ～２．０ｍｍ程度となっている。異方導電テープＴの厚さは、５μｍ～１００μｍ、好ましくは１０μｍ～４０μｍ、より好ましくは１０μｍ～２０μｍ程度となっている。基材の厚さは、異方導電テープＴの厚さと同程度となっている。 The anisotropic conductive tape T wound around the winding core 2 is, for example, as a connecting material for performing electrical connection and mechanical fixing so as to maintain electrical continuity between the opposing electrodes and to maintain insulation between the adjacent electrodes. used. The length of the anisotropic conductive tape T is usually about 50 m to about 1000 m, and is 300 m or more in the present embodiment. The length of the anisotropic conductive tape T is preferably 200 m to 1000 m, and more preferably 250 m to 500 m. The width of the anisotropic conductive tape T is about 0.5 mm to 10 mm, preferably about 0.5 mm to 3.0 mm, and more preferably about 0.5 mm to 2.0 mm. The thickness of the anisotropic conductive tape T is about 5 μm to 100 μm, preferably 10 μm to 40 μm, and more preferably about 10 μm to 20 μm. The thickness of the base material is approximately the same as the thickness of the anisotropic conductive tape T.
　基材は、例えば、ポリエチレンテレフタレート、ポリエチレンナフタレート、ポリエチレンイソフタレート、ポリブチレンテレフタレート、ポリオレフィン、ポリアセテート、ポリカーボネート、ポリフェニレンサルファイド、ポリアミド、エチレン・酢酸ビニル共重合体、ポリ塩化ビニル、ポリ塩化ビニリデン、合成ゴム系、液晶ポリマー等からなる各種プラスチックテープ、又は、銅、アルミニウム等の金属箔を使用することが可能である。もっとも、基材を構成する材質はこれらに限定されるものではない。また、基材として、接着剤層との当接面等に離型処理が施されたものを使用してもよい。基材の一方面上に設けられた接着剤層上に、さらに接着剤層を保護するためのカバーフィルムが積層されたものを使用しても構わない。 The base material is, for example, polyethylene terephthalate, polyethylene naphthalate, polyethylene isophthalate, polybutylene terephthalate, polyolefin, polyacetate, polycarbonate, polyphenylene sulfide, polyamide, ethylene / vinyl acetate copolymer, polyvinyl chloride, polyvinylidene chloride, synthesis It is possible to use various plastic tapes made of rubber, liquid crystal polymer or the like, or metal foils such as copper and aluminum. However, the material which comprises a base material is not limited to these. Moreover, you may use as a base material the thing in which the mold release process was performed in the contact surface etc. with an adhesive bond layer. You may use what laminated | stacked the cover film for protecting an adhesive bond layer further on the adhesive bond layer provided on one side of the base material.
　接着剤層は、例えば、接着剤成分と、必要により含有される導電粒子とを含んでなる接着剤組成物からなる。接着剤成分としては、例えば、熱や光により硬化性を示す材料を広く適用できる。接続後の耐熱性や耐湿性に優れていることから、架橋性材料の使用が好ましい。熱硬化性樹脂であるエポキシ樹脂を主成分として含有するエポキシ系接着剤は、短時間硬化が可能で接続作業性がよく、分子構造上接着性に優れている等の特徴から好ましい。また、国際公開２００９／０６３８２７号に記載されるようなラジカル硬化系の接着剤組成物も使用することができる。 The adhesive layer comprises, for example, an adhesive composition comprising an adhesive component and optionally contained conductive particles. As the adhesive component, for example, a material that exhibits curability by heat or light can be widely applied. The use of a crosslinkable material is preferred because it is excellent in heat resistance and moisture resistance after connection. An epoxy-based adhesive containing an epoxy resin which is a thermosetting resin as a main component is preferable because it can be cured for a short time, has good connection workability, and is excellent in adhesiveness in molecular structure. Also, adhesive compositions of a radical curing system as described in WO 2009/0638827 can be used.
　エポキシ系接着剤は、例えば高分子量エポキシ、固形エポキシ又は液状エポキシ、あるいは、これらをウレタン、ポリエステル、アクリルゴム、ニトリルゴム（ＮＢＲ）、合成線状ポリアミド等で変性したエポキシを主成分とするものを使用することができる。エポキシ系接着剤は、主成分をなす上記エポキシに硬化剤、触媒、カップリング剤、充填剤等を添加してなるものが一般的である。 The epoxy-based adhesive includes, for example, high molecular weight epoxy, solid epoxy or liquid epoxy, or epoxy-modified epoxy or epoxy, which is modified with urethane, polyester, acrylic rubber, nitrile rubber (NBR), synthetic linear polyamide, etc. It can be used. The epoxy-based adhesive is generally formed by adding a curing agent, a catalyst, a coupling agent, a filler and the like to the above-mentioned epoxy as the main component.
　導電粒子としては、例えばＡｕ、Ａｇ、Ｐｔ、Ｎｉ、Ｃｕ、Ｗ、Ｓｂ、Ｓｎ、はんだ等の金属やカーボンの粒子が挙げられる。また、非導電性のガラス、セラミック、プラスチック等を核とし、この核を上記の金属やカーボンで被覆した被覆粒子を使用してもよい。導電粒子の平均粒径は分散性、導電性の観点から１μｍ～１８μｍであることが好ましい。なお、導電粒子を絶縁層で被覆してなる絶縁被覆粒子を使用してもよく、隣接する電極同士の絶縁性を向上させる観点から導電粒子と絶縁性粒子とを併用してもよい。 Examples of conductive particles include particles of metals such as Au, Ag, Pt, Ni, Cu, W, Sb, Sn, solder, and carbon, and carbon. Alternatively, coated particles may be used in which nonconductive glass, ceramic, plastic or the like is used as a core and the core is coated with the above metal or carbon. The average particle diameter of the conductive particles is preferably 1 μm to 18 μm from the viewpoint of dispersibility and conductivity. In addition, you may use the insulation coating particle | grains which coat | cover an electroconductive particle by an insulating layer, and it may use together an electroconductive particle and insulating particles from a viewpoint of improving the insulation of adjacent electrodes.
　導電粒子の配合割合は、接着剤層に含まれる接着剤成分１００体積部に対して、０．１～３０体積部であることが好ましく、０．１～１０体積部であることがより好ましい。この配合割合が０．１体積部未満であると対向する電極間の接続抵抗が高くなる傾向にあり、３０体積部を超えると隣接する電極間の短絡が生じやすくなる傾向がある。なお、これら接着剤層に含有される成分、その配合量、配合方法などについては国際公開２００９／０６３８２７号に記載される成分、その配合量、配合方法などを使用することが可能である。 The proportion of the conductive particles is preferably 0.1 to 30 parts by volume, and more preferably 0.1 to 10 parts by volume, with respect to 100 parts by volume of the adhesive component contained in the adhesive layer. If the blending ratio is less than 0.1 parts by volume, the connection resistance between the facing electrodes tends to be high, and if it exceeds 30 parts by volume, a short circuit between the adjacent electrodes tends to easily occur. In addition, about the component contained in these adhesive bond layers, its compounding quantity, the compounding method, it is possible to use the component, the compounding quantity, the compounding method, etc. which are described in international publication 2009/063827.
　続いて、上述した側板３の構成について更に詳細に説明する。 Subsequently, the configuration of the side plate 3 described above will be described in more detail.
　図１に示すように、側板３の内側面３ａには、側板３の中心側から周縁側にかけて延在する複数のリブ６が設けられている。より具体的には、リブ６は、内側面３ａにおける巻芯２との接合部から周縁部３ｂにかけて直線状に延在し、例えば４５°の間隔をもって８本ずつ設けられている。また、リブ６の断面形状は、例えば円弧状となっており、側板３の内側面３ａからのリブ６の突出量は、０．０５ｍｍ～１．００ｍｍ程度となっている。 As shown in FIG. 1, the inner side surface 3 a of the side plate 3 is provided with a plurality of ribs 6 extending from the center side to the peripheral side of the side plate 3. More specifically, the ribs 6 linearly extend from the joint portion of the inner side surface 3a with the winding core 2 to the peripheral portion 3b, and eight ribs 6 are provided at intervals of, for example, 45 °. The cross-sectional shape of the rib 6 is, for example, a circular arc, and the amount of projection of the rib 6 from the inner side surface 3a of the side plate 3 is about 0.05 mm to 1.00 mm.
　ここで、一対の側板３，３は、一方の側板３におけるリブ６の位置と他方の側板３におけるリブ６の位置とが互いにずれた状態で巻芯２に固定されている。一方の側板３のリブ６と他方の側板３のリブ６とのずれ角θは、巻き付ける異方導電テープＴの長さや幅に応じて適宜設定されるが、この実施形態では例えば５°～１５°となっている。 Here, the pair of side plates 3 and 3 is fixed to the winding core 2 in a state in which the position of the rib 6 in one side plate 3 and the position of the rib 6 in the other side plate 3 are mutually offset. The shift angle θ between the rib 6 of one side plate 3 and the rib 6 of the other side plate 3 is appropriately set according to the length and width of the anisotropic conductive tape T to be wound, but in this embodiment, for example, 5 ° to 15 ° has become.
　このような接着テープ用リール１では、一対の側板３，３間において、巻芯２に巻き付けられた異方導電テープＴは、図３に示すように、互いにずれた状態のリブ６，６に点接触しながら緩やかなＳ字状に湾曲することとなる。したがって、異方導電テープＴの側部Ｔａと側板３の内側面３ａとが直接的に接触することを回避できる。また、この接着テープ用リール１では、リブ６，６が異方導電テープＴの同位置を挟み込むことがないので、異方導電テープＴに過剰な力が加わることも抑制される。したがって、異方導電テープＴに基材からの接着剤層の剥がれ（ブロッキング現象）が発生するきっかけが生じにくくなり、ブロッキング現象の抑制が図られる。 In such an adhesive tape reel 1, the anisotropic conductive tape T wound around the winding core 2 between the pair of side plates 3, 3 is, as shown in FIG. It will be curved in a gentle S-shape while point contact. Therefore, direct contact between the side portion Ta of the anisotropic conductive tape T and the inner side surface 3a of the side plate 3 can be avoided. Further, in the adhesive tape reel 1, since the ribs 6 and 6 do not sandwich the same position of the anisotropic conductive tape T, application of an excessive force to the anisotropic conductive tape T is also suppressed. Therefore, it is difficult to cause an occurrence of peeling (blocking phenomenon) of the adhesive layer from the base on the anisotropic conductive tape T, and the blocking phenomenon can be suppressed.
　また、接着テープ用リール１では、一方の側板３におけるリブ６の位置と他方の側板３におけるリブ６の位置とがずれた状態となっていることで、図４に示すように、リブ６，６の位置が一致している場合の側板３，３間の距離Ｗ２に比べて側板３，３間の距離Ｗ１を小さくできる。これにより、巻き付け作業時に異方導電テープＴが側板３，３によって精度良くガイドされるので、作業効率の向上が図られる。 Further, in the adhesive tape reel 1, as shown in FIG. 4, the rib 6, as shown in FIG. 4, is in a state in which the position of the rib 6 on one side plate 3 and the position of the rib 6 on the other side plate 3 The distance W1 between the side plates 3 and 3 can be made smaller than the distance W2 between the side plates 3 and 3 when the positions of 6 coincide with each other. As a result, since the anisotropic conductive tape T is accurately guided by the side plates 3 and 3 at the time of the winding operation, the working efficiency can be improved.
　なお、一方の側板３におけるリブ６の位置と他方の側板３におけるリブ６の位置とがずれた状態となっていることで、異方導電テープＴの片側にリブ６が位置していたとしても、その反対側には側板３の内側面３ａとの間でスペースが存在することとなる。したがって、異方導電テープＴにリブ６側から衝撃が加わったとしても、反対側の側板３に当たらない範囲であれば、異方導電テープＴが受けるダメージを緩和できると考えられる。反対側の側板３から衝撃が加わった場合でも、反対側の側板３に当たらない範囲であれば、異方導電テープＴが受けるダメージを緩和できると考えられる。また、異方導電テープＴが反対側の側板３に当たってしまうような衝撃が加わったとしても、異方導電テープＴがリブ６，６で挟まれる場合と比較すれば、片側が側板３の内側面３ａであるため、異方導電テープＴが受けるダメージを緩和できると考えられる。 In addition, even if the rib 6 is positioned on one side of the anisotropic conductive tape T, the position of the rib 6 in one side plate 3 and the position of the rib 6 in the other side plate 3 are shifted. There is a space between the inner surface 3a of the side plate 3 and the opposite side. Therefore, even if an impact is applied to the anisotropic conductive tape T from the rib 6 side, it is considered that the damage to the anisotropic conductive tape T can be alleviated as long as the side plate 3 on the opposite side is not hit. Even when an impact is applied from the side plate 3 on the opposite side, it is considered that the damage to the anisotropic conductive tape T can be alleviated as long as the side plate 3 on the opposite side is not hit. In addition, even if an impact is applied such that the anisotropic conductive tape T hits the opposite side plate 3, one side is the inner surface of the side plate 3 as compared to the case where the anisotropic conductive tape T is sandwiched by the ribs 6, 6. Since it is 3a, it is thought that the damage which anisotropic conductive tape T receives can be relieved.
　もっとも、図５に示すように、より幅の小さい異方導電テープＴを巻芯２に巻き付ける場合には、異方導電テープＴが互いにずれた状態のリブ６，６に点接触したとしてもＳ字状の湾曲が生じないようにすることも可能である。この場合は、Ｓ字状の湾曲が生じない分、異方導電テープＴに加わる負荷を小さくすることができ、異方導電テープＴの信頼性の向上が図られる。 However, as shown in FIG. 5, when winding an anisotropic conductive tape T having a smaller width around the core 2, even if the anisotropic conductive tapes T make point contact with the ribs 6, 6 in a state of being mutually shifted, S It is also possible to prevent the occurrence of letter-like curvature. In this case, the load applied to the anisotropic conductive tape T can be reduced because the S-shaped bending does not occur, and the reliability of the anisotropic conductive tape T can be improved.
　この接着テープ用リール１の巻芯２に巻き付けられる異方導電テープＴは、例えば、長さ３００ｍ以上、幅０．５ｍｍ～１．３ｍｍ程度の長尺幅細のテープが想定されている。 The anisotropic conductive tape T wound around the core 2 of the adhesive tape reel 1 is, for example, a long thin tape with a length of 300 m or more and a width of about 0.5 mm to 1.3 mm.
　長さが３００ｍ以上の長尺テープでは、巻重体が大径化し、巻き取り時に巻重体の側面にうねりが発生し易く、異方導電テープＴの側部Ｔａと側板３の内側面３ａとの直接的な接触が特に発生し易い傾向がある。したがって、上述したように、一方の側板３におけるリブ６の位置と他方の側板３におけるリブ６の位置とがずれた状態となっていることで、長尺テープに対してもブロッキング現象の発生を効果的に防止できる。また、長尺テープでは、巻芯２への巻数が増加するため、巻き付け作業の効率向上による製造コストの低減効果も顕著に得られる。 In the case of a long tape having a length of 300 m or more, the diameter of the wound body is increased, and waviness is easily generated on the side surface of the wound body during winding, and the side Ta of the anisotropic conductive tape T and the inner side surface 3a of the side plate 3 Direct contact is particularly prone to occur. Therefore, as described above, the position of the rib 6 in one side plate 3 and the position of the rib 6 in the other side plate 3 are deviated from each other, thereby causing the occurrence of the blocking phenomenon also to the long tape. It can be effectively prevented. Further, in the case of a long tape, since the number of turns around the winding core 2 increases, the reduction effect of the manufacturing cost due to the improvement of the efficiency of the winding operation can be remarkably obtained.
　また、幅が０．５ｍｍ～１．３ｍｍの幅細テープでは、巻芯２に巻き付けを行う際にテープが側板３と巻重体との間の隙間に入り込み易い傾向がある。したがって、上述したように、巻き付け作業時に異方導電テープＴが側板３，３によって精度良くガイドされることで、異方導電テープＴの巻重体の側部のうねりの発生を抑えることが可能となる。 In addition, in the case of a narrow tape having a width of 0.5 mm to 1.3 mm, the tape tends to easily enter the gap between the side plate 3 and the stack when winding around the core 2. Therefore, as described above, the anisotropic conductive tape T is accurately guided by the side plates 3 and 3 at the time of the winding operation, so that the occurrence of the waviness of the side portion of the wound body of the anisotropic conductive tape T can be suppressed. Become.
　異方導電テープＴは、巻芯２に巻き取る最初の部分（巻き始めの部分）が巻芯２に固定されている。この固定方法としては、周知の方法を使用できるが、例えば、粘着テープ、粘着剤により固定することができる。また、巻芯２に留め具や切り込み部を設けて固定することもできる。この中でも作業性の観点から粘着テープ又は粘着剤を使用して固定することが好ましい。 The anisotropic conductive tape T is fixed to the core 2 at a first portion (portion at the start of winding) to be wound around the core 2. As a fixing method, a known method can be used, and for example, it can be fixed by an adhesive tape or an adhesive. In addition, the winding core 2 can be fixed by providing a fastener or a cut portion. Among these, it is preferable to fix using an adhesive tape or an adhesive from the viewpoint of workability.
　本発明は、上記実施形態に限られるものではない。例えば上述した実施形態では、接着テープとして異方導電テープＴを例示したが、接着剤層が接着剤成分からなり導電粒子を含有しない非導電テープを用いてもよく、導電粒子を異方導電テープよりも多く配合した異方性を有さない導電テープを用いてもよい。また、ダイボンドフィルム、銀フィルム、半導体ウエハ加工用の接着フィルムなど各種の接着フィルムにも適用可能である。また、太陽電池セルの電極とタブ線とを接続する導電テープにも好ましく適用可能である。また、例えば上述した実施形態では、側板３，３に８本ずつのリブ６を設けているが、リブ６の数は適宜変更が可能であり、例えば図６～図８に示すように、側板３，３のそれぞれに４本、６本、１０本、１２本、１６本、２０本のリブ６を設けるようにしてもよい。 The present invention is not limited to the above embodiment. For example, in the embodiment described above, the anisotropic conductive tape T is exemplified as the adhesive tape, but a non-conductive tape in which the adhesive layer is made of an adhesive component and does not contain conductive particles may be used. You may use the electrically conductive tape which does not have the anisotropy mix | blended more than it. Moreover, it is applicable also to various adhesive films, such as a die-bonding film, a silver film, and an adhesive film for semiconductor wafer processing. Moreover, it is preferably applicable also to the electrically conductive tape which connects the electrode of a photovoltaic cell, and a tab wire. For example, although eight ribs 6 are provided on each of the side plates 3 and 3 in the embodiment described above, the number of the ribs 6 can be changed as appropriate. For example, as shown in FIGS. Three, four, six, ten, twelve, sixteen, and twenty ribs 6 may be provided on each of three and three, respectively.
　リブ６のずれ角は、リブの本数により適宜変更することができるが、一般的には、３°～４５°程度であることが好ましく、５°～３０°であることがより好ましく、５°～１５°であることが更に好ましく、７．５°～１５°であることが特に好ましい。リブ６のずれ角θは、リブ６が４本の場合には、５°～４５°の範囲で設定されることが好ましく、リブ６が６本の場合には、５°～３０°の範囲で設定されることが好ましい。また、ずれ角θは、リブ６が８本の場合には、５°～２２．５°の範囲で設定されることが好ましく、リブ６が１０本の場合には、５°～１８°の範囲で設定されることが好ましい。 The offset angle of the ribs 6 can be appropriately changed according to the number of ribs, but generally, it is preferably about 3 ° to 45 °, more preferably 5 ° to 30 °, and 5 ° It is further preferable that the angle be 15 °, and it is particularly preferable that the angle be 7.5 ° to 15 °. The displacement angle θ of the rib 6 is preferably set in the range of 5 ° to 45 ° in the case of four ribs 6 and in the range of 5 ° to 30 ° in the case of six ribs 6 It is preferable to set at. The deviation angle θ is preferably set in the range of 5 ° to 22.5 ° in the case of eight ribs 6, and is in the range of 5 ° to 18 ° in the case of ten ribs 6. It is preferable to set in the range.
　また、ずれ角θは、リブ６が１２本の場合には、５°～１５°の範囲で設定されることが好ましく、リブ６が１６本の場合には、５°～１１．２５°の範囲で設定されることが好ましい。さらに、リブ６が２０本の場合には、５°～９°の範囲で設定されることが好ましい。なお、上記の各場合において、ずれ角θの下限を７．５°にすることが好ましく、リブ６の本数が４本～１６本の場合には、ずれ角の下限を１０°にすることが更に好ましい。 In addition, the deviation angle θ is preferably set in the range of 5 ° to 15 ° in the case of 12 ribs 6, and is 5 ° to 11.25 ° in the case of 16 ribs 6. It is preferable to set in the range. Furthermore, in the case of 20 ribs 6, it is preferable to set in the range of 5 ° to 9 °. In each of the above cases, the lower limit of the deviation angle θ is preferably 7.5 °, and in the case where the number of the ribs 6 is 4 to 16, the lower limit of the deviation angle may be 10 ° More preferable.
　また、側板３におけるリブ６の間隔は、必ずしも等間隔である必要はなく、一方の側板３のリブ６の数と他方の側板３のリブ６の数とは、必ずしも一致していなくてもよい。例えば図９（ａ）に示すように、一方の側板３に等間隔で４本のリブ６を設けると共に、他方の側板３に５°～１０°程度の間隔を空けたリブ６，６の対を等間隔で４対設け、これらのリブ６が互いにずれた状態となるように側板３，３同士を固定してもよい。 Moreover, the intervals of the ribs 6 in the side plate 3 do not necessarily have to be equal intervals, and the number of the ribs 6 in one side plate 3 and the number of the ribs 6 in the other side plate 3 do not necessarily have to match. . For example, as shown in FIG. 9A, four ribs 6 are provided on one side plate 3 at equal intervals, and the other side plate 3 is provided with a pair of ribs 6 and 6 spaced about 5 ° to 10 °. May be provided at equal intervals, and the side plates 3 and 3 may be fixed so that the ribs 6 are offset from each other.
　また、例えば図９（ｂ）に示すように、一方の側板３に等間隔で４本のリブ６を設けると共に、他方の側板３に等間隔で８本のリブ６を設け、これらのリブ６が互いにずれた状態となるように側板３，３同士を固定してもよい。さらに、例えば図９（ｃ）に示すように、一方の側板３に等間隔で４本のリブ６を設けると共に、他方の側板３に８本のリブ６を設け、側板３，３同士を固定したときに、計１２本のリブ６が等間隔で並ぶようにしてもよい。なお、全てのリブのずれ角が一定である必要もなく、一部のリブのずれ角が他のリブのずれ角と異なるように設計されてもよい。また、必要によってはリブの一部がずれ角を有さない状態であってもよい。 For example, as shown in FIG. 9 (b), four ribs 6 are provided on one side plate 3 at equal intervals, and eight ribs 6 are provided on the other side plate 3 at equal intervals. The side plates 3 and 3 may be fixed so that they are shifted from each other. Furthermore, for example, as shown in FIG. 9 (c), while providing four ribs 6 on one side plate 3 at equal intervals, providing eight ribs 6 on the other side plate 3 and fixing the side plates 3, 3 to each other In this case, a total of 12 ribs 6 may be arranged at equal intervals. The offset angles of all ribs do not have to be constant, and the offset angles of some ribs may be designed to be different from the offset angles of other ribs. In addition, if necessary, a part of the rib may not have a deviation angle.
　さらに、図１０に示すように、巻芯２に巻き付けられた接着テープの残量を視認するための窓Ｗを側板３に設けるようにしてもよい。この場合、図１０（ａ）に示すように、側板３におけるリブ６，６間のスペースに窓Ｗを設けてもよく、図１０（ｂ）に示すように、リブ６，６の対を１箇所設けない代わりに窓Ｗを設けるようにしてもよい。また、図１０（ｃ）に示すように、リブ６，６の対の一部を切り抜くようにして窓Ｗを設けるようにしてもよい。 Furthermore, as shown in FIG. 10, the side plate 3 may be provided with a window W for visually recognizing the remaining amount of the adhesive tape wound around the winding core 2. In this case, the window W may be provided in the space between the ribs 6 and 6 in the side plate 3 as shown in FIG. 10 (a), and as shown in FIG. 10 (b) The window W may be provided instead of providing the portion. Further, as shown in FIG. 10C, the window W may be provided by cutting out a part of the pair of ribs 6, 6.
　また、リブ６の平面形状は、図１に示したような巻芯２側から周縁部３ｂにかけて直線状に延在するものに限られず、図１１（ａ）に示すように、断続的に形成されたものであってもよく、図１１（ｂ）に示すように、側板３の中心を向かずに径方向と交差するように形成してもよい。また、図１１（ｃ）に示すように、波線状に形成してもよい。 Further, the planar shape of the rib 6 is not limited to one extending linearly from the winding core 2 side to the peripheral edge portion 3b as shown in FIG. 1, but is intermittently formed as shown in FIG. Alternatively, as shown in FIG. 11B, the side plate 3 may be formed so as to intersect with the radial direction without being directed to the center. Moreover, as shown in FIG.11 (c), you may form in a wavy line shape.
　また、リブ６の断面形状は、図３に示したような円弧状のものに限られず、図１２に示すように、三角形状、矩形状、矩形状の角部を面取りした形状、これらを並べたものなどの種々の形状を採用できる。さらに、図１３（ａ）～（ｃ）に示すように、側板３の周縁部３ｂにも、別のリブ７を設けるようにしてもよい。このほか、周縁部３ｂのリブ７は、側板３の周縁部３ｂの全周にわたって設けてもよいし、断続的に設けてもよい。また、リブ７は、波線状に設けてもよく、周縁部３ｂに沿って２重・３重に設けてもよい。 Moreover, the cross-sectional shape of the rib 6 is not limited to the arc-shaped one as shown in FIG. 3, but as shown in FIG. 12, triangular, rectangular, rectangular chamfered corner parts, these are arranged Various shapes, such as a thing, can be adopted. Further, as shown in FIGS. 13 (a) to 13 (c), another rib 7 may be provided on the peripheral portion 3b of the side plate 3. Besides, the ribs 7 of the peripheral portion 3 b may be provided over the entire circumference of the peripheral portion 3 b of the side plate 3 or may be provided intermittently. Further, the ribs 7 may be provided in a wavy shape, or may be provided in two or three along the peripheral portion 3 b.
　なお、側板３の周縁部３ｂにリブ７を設ける場合、一方の側板３のリブ７の位置と他方の側板のリブ７の位置とが一致する場合があるが、上述したように、側板３，３間の距離は、側板３の周縁側ほど広がる傾向にあるので、側板３，３間の距離Ｗ１を小さくできるという効果が阻害されることはない。この効果を担保するため、リブ７の高さをリブ６の高さに比べて低く形成してもよい。 When the rib 7 is provided on the peripheral portion 3b of the side plate 3, the position of the rib 7 of one side plate 3 may coincide with the position of the rib 7 of the other side plate, but as described above, the side plate 3, The distance between the side plates 3 and 3 tends to widen toward the peripheral side of the side plate 3, and therefore, the effect of reducing the distance W1 between the side plates 3 and 3 is not impaired. In order to secure this effect, the height of the rib 7 may be formed lower than the height of the rib 6.
　また、接着テープ用リール１は、図２に示したように一対の側板３，３が巻芯２を挟むように互いに対向して設けられたものに限られない。例えば、巻芯２が一対の側板３，３の外側へ突出するように設けられていても構わない。 Further, the adhesive tape reel 1 is not limited to one provided with the side plates 3 and 3 facing each other so as to sandwich the winding core 2 as shown in FIG. For example, the winding core 2 may be provided to protrude to the outside of the pair of side plates 3 and 3.
　また、上述した接着テープ用リール１においては、巻芯２に異方導電テープＴが巻き付けられていたが、巻芯２に捲き付けられるテープはこれに限られない。異方導電テープＴに代え、接着剤層が接着剤成分からなり導電粒子を含有しない非導電テープを巻芯２に巻き付けてもよい。また、異方導電テープＴに代え、導電粒子を異方導電テープＴよりも多く配合した異方性を有さない導電テープを巻芯２に巻き付けてもよい。上記以外の巻芯２に捲き付けられるテープとしては、ダイボンドフィルム、銀フィルム、半導体ウエハ加工用の接着フィルムなど各種の電子材料用の接着フィルムを適用することができる。 In the adhesive tape reel 1 described above, the anisotropic conductive tape T is wound around the winding core 2, but the tape wound onto the winding core 2 is not limited to this. Instead of the anisotropic conductive tape T, the core 2 may be wound with a non-conductive tape in which the adhesive layer is made of an adhesive component and does not contain conductive particles. Also, instead of the anisotropic conductive tape T, a conductive tape having no conductive particles mixed with more conductive particles than the anisotropic conductive tape T may be wound around the core 2. As a tape wound on the core 2 other than the above, adhesive films for various electronic materials such as a die bond film, a silver film, and an adhesive film for processing a semiconductor wafer can be applied.
