また、本発明に係るリールは、前記凸部が、径方向に延在するように設けられている構成とすることができる。この場合、前記凸部が、放射状に設けられている構成とするのが好ましい。
このような構成とすれば、接着剤層を形成する接着剤のリール内側面への付着をより確実に防止することができる。 Moreover, the reel which concerns on this invention can be set as the structure by which the said convex part was provided so that it might extend in radial direction. In this case, it is preferable that the convex portions are provided radially.
With such a configuration, it is possible to more reliably prevent adhesion of the adhesive forming the adhesive layer to the inner surface of the reel.

また、本発明に係るリールは、不具合を伴うことなく、より確実にリール内側面への接着剤の付着をより確実に防止する上で、前記径方向凸部が、高さ０．０５〜１．００ｍｍ、幅０．５〜２０．０ｍｍであるのが好ましい。   Further, the reel according to the present invention has a height of 0.05 to 1 in order to prevent the adhesive from adhering to the inner surface of the reel more surely without causing any trouble. It is preferably 0.000 mm and a width of 0.5 to 20.0 mm.

また、本発明に係るリールは、一方、又は両方の前記側板部の周縁部に沿った内側面に、周方向に延在する周縁凸部を設けた構成とすることができる。
このような構成とすれば、被巻き取り物である接着テープの側面を側板部の周縁部でガイドして、巻むらが生じないように接着テープを巻き取っていくに際し、接着テープとの接触面積を小さくして、側板部の周縁部への接着剤の付着を防止することができる。 Moreover, the reel which concerns on this invention can be set as the structure which provided the peripheral convex part extended in the circumferential direction in the inner surface along the peripheral part of the said one side plate part or both.
With such a configuration, the side surface of the adhesive tape that is the object to be wound is guided by the peripheral edge of the side plate portion, and when the adhesive tape is wound up so that winding unevenness does not occur, contact with the adhesive tape By reducing the area, adhesion of the adhesive to the peripheral edge of the side plate portion can be prevented.

また、本発明に係るリールは、被巻き取り物である接着テープとの接触面積を小さくする上で、被巻き取り物の側面を前記側板部の周縁部でガイドして巻き取る際に、少なくとも前記周縁凸部の前記被巻き取り物と接触する部位を円弧状とするのが好ましい。   Further, the reel according to the present invention has at least a side surface of the article to be wound, guided by the peripheral edge portion of the side plate portion and wound, in order to reduce the contact area with the adhesive tape that is the article to be wound. It is preferable that the portion of the peripheral convex portion that comes into contact with the article to be wound has an arc shape.

また、本発明に係るリールは、不具合を伴うことなく、より確実に側板部の周縁部への接着剤の付着をより確実に防止する上で、前記周縁凸部が、高さ０．０５〜１．００ｍｍ、幅０．５〜２０．０ｍｍであるのが好ましい。   In addition, the reel according to the present invention has a height of 0.05 to 0.05 in order to more reliably prevent adhesion of the adhesive to the peripheral edge of the side plate portion without any trouble. It is preferably 1.00 mm and a width of 0.5 to 20.0 mm.

また、本発明に係るリールは、被巻き取り物を、接着剤層又は粘着剤層を備えたものとすることができ、一般に、粘着剤と称されるような材料を用いて塗工形成された粘着剤層を備えた被巻き取り物にも好適に適用して、粘着剤の付着を防止することができる。   In addition, the reel according to the present invention can have an article to be wound provided with an adhesive layer or a pressure-sensitive adhesive layer, and is generally formed by coating using a material called a pressure-sensitive adhesive. The adhesive can be suitably applied to an article to be wound having an adhesive layer to prevent the adhesion of the adhesive.

このような本発明によれば、接着剤層又は粘着剤層が塗工形成されたフィルム材を細幅のテープ状に切断しながらリールに巻き取る際や、巻き取り保管時に、接着剤層又は粘着剤層を形成する接着剤又は粘着剤が、リールの内側面に付着するのを防止することができ、これによって製品不良の発生を抑えて歩留まりを向上させることができる。   According to the present invention, when the film material on which the adhesive layer or the pressure-sensitive adhesive layer is coated and formed is wound into a reel while being cut into a thin tape shape, It is possible to prevent the adhesive or pressure-sensitive adhesive forming the pressure-sensitive adhesive layer from adhering to the inner surface of the reel, thereby suppressing the occurrence of product defects and improving the yield.

以下、本発明の好ましい実施形態について、図面を参照しながら説明する。
なお、図１は、本実施形態に係るリールの概略を示す説明図であり、図１（ａ）は正面図、図１（ｂ）は図１（ａ）のＡ−Ａ断面図である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1A and 1B are explanatory views showing an outline of the reel according to the present embodiment. FIG. 1A is a front view, and FIG. 1B is a cross-sectional view taken along line AA in FIG.

図1に示すリール１は、円柱状の巻き取り部３と、この巻き取り部３を挟んで平行又はほぼ平行に対向するように取り付けられた一対の側板部２，２とを備えて構成されている。また、リール１のほぼ中央には、Ｄ穴形状の軸穴４が貫通して設けられており、この軸穴４に、図示しない巻き取り装置の巻き取り軸を挿通することで、当該巻き取り装置にリール１が装着され、巻き取り軸の駆動に伴って回転するようになっている。   The reel 1 shown in FIG. 1 includes a cylindrical winding portion 3 and a pair of side plate portions 2 and 2 attached so as to face each other in parallel or substantially in parallel with the winding portion 3 interposed therebetween. ing. Further, a D-hole-shaped shaft hole 4 is provided through substantially the center of the reel 1. By inserting a winding shaft of a winding device (not shown) into the shaft hole 4, the winding is performed. A reel 1 is mounted on the apparatus, and rotates as the take-up shaft is driven.

このような構成のリール１は、接着剤層が塗工形成されたフィルム材を、細幅のテープ状に切断しながら巻き取って、種々の接着テープ５を製造、供給する際に用いられるものであり、巻き取り部３の幅、すなわち、巻き取り部３を介して隔てられた側板部２，２の間の距離は、被巻き取り物である接着テープ５の切断幅に応じて適宜設定することができる。また、側板部２は、一般には、円板状に形成されるが、その径は、接着テープ５の巻き取り長さに応じて適宜設定することができる。   The reel 1 having such a configuration is used for manufacturing and supplying various adhesive tapes 5 by winding a film material coated with an adhesive layer while cutting it into a thin tape. The width of the winding part 3, that is, the distance between the side plate parts 2 and 2 separated via the winding part 3, is set as appropriate according to the cutting width of the adhesive tape 5 that is to be wound. can do. The side plate portion 2 is generally formed in a disc shape, but the diameter thereof can be appropriately set according to the winding length of the adhesive tape 5.

本実施形態において、リール１は、射出成形などにより一体に成形されたものであってもよいが、一対の側板部２，２と巻き取り部３とを別体に形成し、これらを嵌合、接着などの適宜手段により接合一体化するようにしてもよい。側板部２，２と巻き取り部３とを別体とすれば、例えば、巻き取り部３を共通とし、これに異なる径の側板部２を組み合わせることで、種々の巻き取り長さに対応させたり、共通の側板部２に幅の異なる巻き取り部３を組み合わせることで、種々の切断幅に対応させたりすることができる。   In this embodiment, the reel 1 may be integrally formed by injection molding or the like, but the pair of side plate portions 2 and 2 and the winding portion 3 are formed separately and are fitted together. Alternatively, they may be joined and integrated by appropriate means such as adhesion. If the side plate portions 2 and 2 and the winding portion 3 are separated, for example, the winding portion 3 is used in common, and the side plate portions 2 having different diameters are combined with the side plate portions 2 and 2 to correspond to various winding lengths. Or, by combining the common side plate portion 2 with the winding portion 3 having different widths, it is possible to correspond to various cutting widths.

また、本実施形態では、側板部２，２の内側面に、図１（ｂ）、及び図２に示すような径方向に延在する凸部２１が設けられている。
なお、図２は、図１（ｂ）のＢ−Ｂ断面を示す端面図である。 Moreover, in this embodiment, the convex part 21 extended in radial direction as shown in FIG.1 (b) and FIG. 2 is provided in the inner surface of the side-plate parts 2 and 2. As shown in FIG.
FIG. 2 is an end view showing a BB cross section of FIG.

側板部２の内側面に設けられる凸部２１は、接着テープ５をリール１に巻き取る際や、接着テープ５の巻き取り保管時に、接着テープ４の側面に露出する接着剤層が、リール１の内側面（側板部２の内側面）に接触してしまうのを抑制し、これによって、接着剤層を形成する接着剤が、リール１の内側面に付着するのを防止するものである。   The convex portion 21 provided on the inner side surface of the side plate portion 2 has an adhesive layer exposed on the side surface of the adhesive tape 4 when the adhesive tape 5 is wound around the reel 1 or when the adhesive tape 5 is wound and stored. This prevents contact with the inner side surface (inner side surface of the side plate portion 2), thereby preventing the adhesive forming the adhesive layer from adhering to the inner side surface of the reel 1.

すなわち、巻き取り部３で隔てられている側板部２，２間の距離は、巻き取り部３に巻き取られる接着テープ５が、側板部２の内側面に接触してしまわないように、接着テープ５の切断幅に応じてある程度の余裕をもって設定されるが、接着テープ５を巻き取る際に、リール１の回転にぶれが生じるなどして接着テープ５の巻き取り位置が偏ってしまったり、巻き取り保管時の衝撃や、振動などによって巻き取られた接着テープ５に位置ずれが生じてしまったりすると、接着テープ５が側板部２の内側面に接触してしまうことがある。
本実施形態では、そのような場合であっても、側板部２の内側面に凸部２１を設けることによって、接着テープ５の側面に露出する接着剤層と、側板部２の内側面との接触面積を小さくし、接着剤層を形成する接着剤がリール１の内側面に付着してしまうのを防止している。 That is, the distance between the side plate portions 2 and 2 separated by the winding portion 3 is such that the adhesive tape 5 wound around the winding portion 3 does not come into contact with the inner surface of the side plate portion 2. Depending on the cutting width of the tape 5, it is set with a certain margin, but when the adhesive tape 5 is wound, the winding position of the adhesive tape 5 is biased due to the rotation of the reel 1. If the positional deviation occurs in the adhesive tape 5 taken up due to impact or vibration during winding and storage, the adhesive tape 5 may come into contact with the inner surface of the side plate portion 2.
In the present embodiment, even in such a case, by providing the convex portion 21 on the inner surface of the side plate portion 2, the adhesive layer exposed on the side surface of the adhesive tape 5 and the inner surface of the side plate portion 2. The contact area is reduced to prevent the adhesive forming the adhesive layer from adhering to the inner surface of the reel 1.

本実施形態において、このような凸部２１を設けるにあたり、凸部２１の高さｈ１は、０．０５〜１．００ｍｍであるのが好ましく、より好ましくは０．０５〜０．３０ｍｍであり、特に好ましくは、０．０５〜０．２０ｍｍである。
凸部２１の高さｈ１が０．０５ｍｍに満たないと、接着テープ５の側板部２の内側面への接触を抑制する効果が得られ難くなってしまう。また、リール１を射出成形する際の条件管理の精度が必要となってくるという点でも好ましくない。逆に、凸部２１の高さｈ１が１．００ｍｍを超えると、凸部２１が必要以上に高くなってしまい、リール１の幅寸法に影響してしまう。また、接着テープ５の側面への押圧が強くなり、接着テープ５の側面に凸部２１の跡が付いてしまう可能性があるという点でも好ましくない。 In this embodiment, when providing such a convex part 21, it is preferable that the height h1 of the convex part 21 is 0.05-1.00 mm, More preferably, it is 0.05-0.30 mm, Especially preferably, it is 0.05-0.20 mm.
If the height h1 of the convex portion 21 is less than 0.05 mm, it is difficult to obtain an effect of suppressing contact of the adhesive tape 5 with the inner surface of the side plate portion 2. Further, it is not preferable in that the accuracy of condition management when the reel 1 is injection-molded becomes necessary. Conversely, when the height h1 of the convex portion 21 exceeds 1.00 mm, the convex portion 21 becomes higher than necessary, which affects the width dimension of the reel 1. Further, it is not preferable in that the pressure on the side surface of the adhesive tape 5 becomes strong, and there is a possibility that a mark of the convex portion 21 may be attached to the side surface of the adhesive tape 5.

また、凸部２１の幅ｗ１は、０．５〜２０．０ｍｍであるのが好ましく、より好ましくは０．５〜１０．０ｍｍであり、特に好ましくは０．５〜５．０ｍｍである。
凸部２１の幅ｗ１が０．５ｍｍに満たないと、接着テープ５の側面を傷つけてしまうおそれがある。また、リール１を射出成形する際の条件管理の精度が必要となってくるという点でも好ましくない。逆に、凸部２１の幅ｗ１が２０．０ｍｍを超えると、凸部２１への接着剤の付着の問題が生じてしまう。 Moreover, it is preferable that the width | variety w1 of the convex part 21 is 0.5-20.0 mm, More preferably, it is 0.5-10.0 mm, Most preferably, it is 0.5-5.0 mm.
If the width w1 of the convex portion 21 is less than 0.5 mm, the side surface of the adhesive tape 5 may be damaged. Further, it is not preferable that accuracy of condition management when the reel 1 is injection-molded becomes necessary. On the contrary, if the width w1 of the convex part 21 exceeds 20.0 mm, the problem of the adhesion of the adhesive agent to the convex part 21 will arise.

また、本実施形態では、図１に示すように、径方向に延在する複数（図示する例では八本）の凸部２１を放射状に設けると、より確実に、接着剤層を形成する接着剤のリール１の内側面への付着を防止することができるため好ましい。   Further, in the present embodiment, as shown in FIG. 1, when a plurality of (eight in the illustrated example) convex portions 21 extending in the radial direction are provided in a radial manner, adhesion that forms an adhesive layer more reliably. It is preferable because the agent can be prevented from adhering to the inner surface of the reel 1.

また、本実施形態では、側板部２の周縁部に沿った内側面に、図１（ｂ）、及び図３に示すような周方向に延在する周縁凸部２２が設けられている。
なお、図３は、図１（ｂ）のＣ−Ｃ断面を示す端面図である。 Moreover, in this embodiment, the peripheral convex part 22 extended in the circumferential direction as shown in FIG.1 (b) and FIG. 3 is provided in the inner surface along the peripheral part of the side-plate part 2. As shown in FIG.
FIG. 3 is an end view showing a CC cross section of FIG.

ここで、細幅に切断された接着テープ５をリール１に巻き取っていくにあたり、図４（ａ）に示すように、接着テープ５を若干傾けながら、接着テープ５の側面を側板部２の周縁部にガイドさせた状態で巻き取っていくと、接着テープ５の側面を面一に揃えて巻むらが生じないように巻き取ることができる。
なお、図４は、接着テープ５の巻き取り状態を示す説明図である。また、図４（ｂ）は、図４（ａ）に示す状態の左側面図であり、図中矢印方向に回転するリール１に接着テープ５が巻き取られていく。 Here, when winding the adhesive tape 5 cut into a narrow width around the reel 1, the side surface of the adhesive tape 5 is placed on the side plate portion 2 while slightly tilting the adhesive tape 5 as shown in FIG. If it winds in the state guided by the peripheral part, it can wind up so that the side surface of the adhesive tape 5 may be made flush and the winding unevenness may not occur.
FIG. 4 is an explanatory view showing a wound state of the adhesive tape 5. 4B is a left side view of the state shown in FIG. 4A, and the adhesive tape 5 is wound around the reel 1 that rotates in the direction of the arrow in the drawing.

本実施形態において、側板部２の周縁部に沿った内側面に設けられる周縁凸部２２は、上記のようにして接着テープ５をリール１に巻き取って行く際に、接着テープ５の側面に露出する接着剤層が、側板部２の周縁部に接触することにより、接着剤層を形成する接着剤が、側板部２の周縁部に付着してしまうのを防止するためのものである。   In the present embodiment, the peripheral convex portion 22 provided on the inner side surface along the peripheral portion of the side plate portion 2 is formed on the side surface of the adhesive tape 5 when the adhesive tape 5 is wound around the reel 1 as described above. This is for preventing the adhesive forming the adhesive layer from adhering to the peripheral portion of the side plate portion 2 when the exposed adhesive layer contacts the peripheral portion of the side plate portion 2.

すなわち、本実施形態では、接着テープ５の側面を側板部２の周縁部でガイドするに際して、接着テープ５との接触面積が小さくなるように、側板部２の周縁部に沿った内側面に、周方向に延在する周縁凸部２２を設け、これによって接着剤の付着を防止している。   That is, in this embodiment, when the side surface of the adhesive tape 5 is guided by the peripheral edge portion of the side plate portion 2, the inner surface along the peripheral portion of the side plate portion 2 is reduced so that the contact area with the adhesive tape 5 is reduced. A peripheral convex portion 22 extending in the circumferential direction is provided to prevent adhesion of the adhesive.

このため、周縁凸部２２は、少なくとも接着テープ５と接触する部位が円弧状になっているのが好ましく、その曲率半径は、粘着テープ５との接触面積を小さくする上で、０．３〜１．５ｍｍであるのが好ましく、より好ましくは０．５〜１．０ｍｍである。   For this reason, it is preferable that the peripheral convex part 22 has an arc shape at least at a portion that contacts the adhesive tape 5, and the radius of curvature is 0.3 to 0.3 to reduce the contact area with the adhesive tape 5. It is preferable that it is 1.5 mm, More preferably, it is 0.5-1.0 mm.

また、本実施形態において、このような周縁凸部２２を設けるにあたり、周縁凸部２２の高さｈ２は、０．０５〜１．００ｍｍであるのが好ましく、より好ましくは０．０５〜０．３０ｍｍであり、特に好ましくは０．０５〜０．２０ｍｍである。
周縁凸部２２の高さｈ２が０．０５ｍｍに満たないと、接着テープ５の側板部２の内側面への接触を抑制する効果が損なわれてしまう。また、接着テープ５を巻き取る際に凸部２１と接着テープ５とが干渉し、接着テープ５に傷が付くおそれがあるという点でも好ましくない。逆に、周縁凸部２２の高さｈ２が１．００ｍｍを超えると、周縁凸部２２が必要以上に高くなってしまい、接着テープ５を巻き取る際に接着テープ５と干渉してしまう。また、接着テープ５を巻き取った後の接着テープ５と側板部２，２との隙間が大きくなるため、保管時の巻きずれが生じるおそれがあるなど、保管安定性が低下してしまうという点でも好ましくない。 Moreover, in this embodiment, when providing such a peripheral convex part 22, it is preferable that the height h2 of the peripheral convex part 22 is 0.05-1.00 mm, More preferably, it is 0.05-0. 30 mm, particularly preferably 0.05 to 0.20 mm.
If the height h2 of the peripheral convex portion 22 is less than 0.05 mm, the effect of suppressing contact of the adhesive tape 5 with the inner surface of the side plate portion 2 is impaired. Moreover, when winding up the adhesive tape 5, the convex part 21 and the adhesive tape 5 interfere, and it is unpreferable also at the point that there exists a possibility that the adhesive tape 5 may be damaged. Conversely, if the height h2 of the peripheral convex portion 22 exceeds 1.00 mm, the peripheral convex portion 22 becomes unnecessarily high and interferes with the adhesive tape 5 when the adhesive tape 5 is wound. Moreover, since the clearance gap between the adhesive tape 5 after winding up the adhesive tape 5 and the side-plate parts 2 and 2 becomes large, there exists a possibility that the winding | winding deviation | shift at the time of storage may arise, and the point that storage stability will fall. But it is not preferable.

また、周縁凸部２２の幅ｗ２は、０．５〜２０．０ｍｍであるのが好ましく、より好ましくは０．５〜１０．０ｍｍであり、特に好ましくは０．５〜５．０ｍｍである。
周縁凸部２２の幅ｗ２が０．５ｍｍに満たないと、接着テープ５の側面を傷つけてしまうおそれがある。逆に、周縁凸部２２の幅ｗ２が２０．０ｍｍを超えると、周縁凸部２２への接着剤の付着の問題が生じてしまう。また、リール１に巻き取られた接着テープ５を巻き出して使用する際に、接着テープ５が周縁凸部２２に引っかかるおそれがあるという点でも好ましくない。 Moreover, it is preferable that the width w2 of the peripheral convex part 22 is 0.5-20.0 mm, More preferably, it is 0.5-10.0 mm, Most preferably, it is 0.5-5.0 mm.
If the width w2 of the peripheral convex portion 22 is less than 0.5 mm, the side surface of the adhesive tape 5 may be damaged. On the contrary, if the width w2 of the peripheral convex portion 22 exceeds 20.0 mm, a problem of adhesion of the adhesive to the peripheral convex portion 22 occurs. Further, when the adhesive tape 5 wound around the reel 1 is unwound and used, it is not preferable in that the adhesive tape 5 may be caught on the peripheral convex portion 22.
