Description
【０００１】[0001]
本考案は、合成樹脂フィルム、合成樹脂シート、織物、紙などの薄箔状物を巻 き取るための巻芯に関する。 The present invention relates to a core for winding a thin foil material such as a synthetic resin film, a synthetic resin sheet, a woven fabric, and paper.
【０００２】[0002]
合成樹脂フィルム、合成樹脂シート、織物、紙などの薄箔状物を巻芯、即ち、 ボビン上に確実に、かつ、損傷することなく巻き上げるには、薄箔状物の端部を 巻芯の軸芯に一致させて固定する必要がある。 しかし、薄箔状物末端の固定が不完全であったり、薄箔状物末端が巻芯の軸芯 と一致していない場合には、巻取り張力が一方に大きく、他方に小さくなる現象 が起こり、薄箔状物に不均一な張力が作用して蛇行することが多い。その結果、 巻装端面がタケノコ状になる。このタケノコ状を阻止すべく蛇行を強制的に修正 すると、部分的な「伸び」や「たるみ」を生じてシワ、折り重なりが生じ、最悪 の場合には、切断に波及するということになる。 In order to wind a thin foil material such as a synthetic resin film, a synthetic resin sheet, a woven fabric, or paper onto a winding core, that is, a bobbin reliably and without damage, the end of the thin foil material should be It is necessary to match and fix the shaft center. However, if the fixing of the end of the thin foil material is not complete or if the end of the thin foil material does not match the axis of the winding core, the winding tension may increase in one direction and decrease in the other. This often occurs, and the thin foil-like material is often meandered due to non-uniform tension. As a result, the wound end surface becomes bamboo shoot-shaped. If the meandering is forcibly corrected to prevent this bamboo shoot shape, partial "stretching" or "slackening" will occur, causing wrinkles and folding, and in the worst case, it will spread to cutting.
【０００３】 一般に、薄箔状物は、加工や印刷の都度、他の巻芯上に巻き替えしを行うこと が多いが、その際に初期段階での薄箔状物末端の固定部が段差となって大きく影 響して表面の平滑さが失われ、繊細な印刷やコーティング処理をする際には、下 層部分に不良品が発生することになる。 薄箔状物（以下、フィルムと称する）の端部を巻芯上に固定する手段としては 、図７（実公昭40- 10567 号公報参照) に示すように、巻芯本体Ｂ上の軸線方向 に感圧接着剤層Ａを直線状に設け、この感圧接着剤層Ａ上にフィルムＦの端部ｆ を接着して固定している。In general, the thin foil-like material is often rewound onto another winding core each time it is processed or printed. At that time, the fixing portion at the end of the thin foil-like material has a step at the initial stage. This greatly affects the surface smoothness, resulting in defective products in the lower layer when performing delicate printing or coating. As shown in FIG. 7 (see Japanese Utility Model Publication No. 40-10567), a means for fixing the end of a thin foil-like material (hereinafter referred to as a film) on the core is as shown in FIG. The pressure-sensitive adhesive layer A is linearly provided on the pressure sensitive adhesive layer A, and the end portion f 1 of the film F is adhered and fixed on the pressure-sensitive adhesive layer A.
【０００４】 しかし、この構造のものにおいては、フィルムＦの幅Ｌの両端部に感圧接着剤 層Ａの露出部ａが存在する。 従って、この感圧接着剤層Ａ上にフィルムＦを巻き取ると、フィルムＦの巻き 締め圧力で感圧接着剤層Ａの一部が感圧接着剤層Ａの露出部ａにはみ出し盛り上 がる（図９の(a) 参照）。However, in this structure, exposed portions a of the pressure-sensitive adhesive layer A exist at both ends of the width L of the film F. Therefore, when the film F is wound on the pressure-sensitive adhesive layer A, a part of the pressure-sensitive adhesive layer A is protruded to the exposed portion a of the pressure-sensitive adhesive layer A by the winding pressure of the film F. (See (a) of FIG. 9).
【０００５】 更に、図９の(b) に示すように、フィルムＦの縁部に感圧接着剤層Ａの露出部 ａの盛り上がり部ａ’が乗り上ったり、図９の(c) のように、感圧接着剤層Ａの 盛り上がり部ａ’がフィルムＦの層間に巻き込まれたりする。 また、フィルムＦの側部に露出部ａが存在すると、巻装中、梱包中、或いは取 扱い中に異物が付着してフィルムＦに汚れが発生する。Further, as shown in FIG. 9 (b), a raised portion a ′ of the exposed portion a of the pressure-sensitive adhesive layer A rides on the edge portion of the film F, or in FIG. 9 (c). Thus, the raised portion a ′ of the pressure-sensitive adhesive layer A may be caught between the layers of the film F. Further, if the exposed portion a exists on the side portion of the film F, foreign matter adheres to the film F during winding, packing, or handling, and the film F is soiled.
【０００６】 更に、フィルム満巻後、取扱い中や輸送中に巻装物に衝撃や振動が作用すると 、図１０のように、フィルムＦにタケノコ状に巻き崩れが発生することがあるが 、このような場合には、感圧接着剤層Ａの露出部ａにフィルムＦの端部が接触し て感圧接着剤層ＡがフィルムＦ側に転移し、それに伴ってフィルムＦに異物が付 着することがある。この様な問題は、巻装中のフィルムが蛇行する場合と同様で ある。Furthermore, after the film has been fully wound, if a shock or vibration is applied to the wound material during handling or transportation, the film F may collapse like a bamboo shoot as shown in FIG. In such a case, the exposed portion a of the pressure-sensitive adhesive layer A is brought into contact with the end portion of the film F, the pressure-sensitive adhesive layer A is transferred to the film F side, and accordingly foreign matter is attached to the film F. I have something to do. Such a problem is similar to the case where the film being wound meanders.
【０００７】 このようになったフィルムＦの両端を細幅にスリッターで切断除去したり、ま た、印刷したり、表面コート処理等の二次加工工程において、異物が付着した部 分が必要ロスとなる。 また、二次加工による巻き替えの際、フィルムＦの端部に感圧接着剤層Ａの接 着剤が付着していると、遠心力と風圧によって上記接着剤やこの接着剤に付着し た異物が飛散したり、装置のロール等に転移汚染し、これが、再度、フィルムＦ に付着して巻き込まれることになる。また、これらの状況からフィルムＦの端部 には、必要ロスとして廃棄することになる。In the secondary processing step such as cutting and removing both ends of the film F with a narrow width by a slitter, printing, and a surface coating treatment, a portion to which foreign matter adheres is required to be lost. Becomes Further, when the adhesive of the pressure-sensitive adhesive layer A was attached to the end portion of the film F during the rewinding by the secondary processing, it was attached to the above-mentioned adhesive or this adhesive due to centrifugal force and wind pressure. The foreign matter scatters or is transferred and contaminated on the rolls of the apparatus, which again adheres to the film F 1 and is caught. Further, under these circumstances, the end portion of the film F is discarded as a necessary loss.
【０００８】 このような欠点を解消するため、巻芯の表面に感圧接着剤をコーテングし、そ の上に、薄い剥離シートで全面被覆し、更に、この剥離シートを部分的に剥離で きるように、切れ目を入れた巻芯が提案されている（実公昭48- 22303 号公報参 照) 。 この考案は、剥離シートの一部を除去して薄箔状物を接着させる部分のみ、接 着剤層を露出させることができる点において優れた考案である。In order to eliminate such drawbacks, a pressure-sensitive adhesive is coated on the surface of the winding core, and a thin release sheet is entirely coated on the pressure-sensitive adhesive, and the release sheet can be partially released. As described above, a core having a slit is proposed (see Japanese Utility Model Publication No. 48-22303). This invention is an excellent idea in that the adhesive layer can be exposed only at the portion where the thin foil-like material is adhered by removing a part of the release sheet.
【０００９】 しかし、この考案でも薄箔状物がフィルムのような平坦度の高いデリケートな 巻装物である場合には、次のような問題がある。即ち、 剥離シートを剥離しない部分においては剥離シートの厚さと接着剤層の厚 さが合計された段差を生ずるために巻装されるフィルムに、この段差が何層にも 転写され、フィルムの下層部分が不良となる欠点がある。また、 接着剤の塗布量のバラツキと巻装中のフィルムの張力ムラ、そして、巻圧 によって接着剤層の厚みの変化が巻装されるフィルムの物性、厚み等の顕著に影 響し、巻き取られたフィルムの表面にうねりが発生し、これがフィルムに複雑な シワ又はタケノコ状の巻装が発生する原因の一つとなる。特に、巻芯の円周方向 に、このシワが発生し易いという問題がある。更に、 フィルムの巻装量が増加するにしたがって接着剤が微妙に移動して剥離シ ートに縦シワ、横シワ、或いは斜めシワが複雑に発生し、これが巻装されるフィ ルムに転写される。この時点で巻芯の再使用は望めない。However, even in this invention, when the thin foil-like material is a delicate wound material with high flatness like a film, there are the following problems. In other words, in the part where the release sheet is not peeled, a step is created by adding the thickness of the release sheet and the thickness of the adhesive layer to each other. There is a defect that the part becomes defective. In addition, variations in the amount of adhesive applied, uneven tension of the film during winding, and changes in the thickness of the adhesive layer due to winding pressure significantly affect the physical properties and thickness of the wound film, and Waviness is generated on the surface of the taken film, which is one of the causes of the occurrence of complicated wrinkles or bamboo shoot-shaped winding on the film. In particular, there is a problem that this wrinkle is likely to occur in the circumferential direction of the winding core. Furthermore, as the amount of film wound increases, the adhesive subtly moves, causing vertical wrinkles, horizontal wrinkles, or diagonal wrinkles in the peeling sheet, which are transferred to the wound film. It At this point, the core cannot be reused.
【００１０】 巻芯を再使用できるとしてもフィルムと接着剤との接触面積が増加するか ら、フィルムに転移する接着剤の量が増大し、巻装されるフィルムの汚染量も増 大することになる。 また、巻芯を再使用すると、接着剤の露出面積が増加し、ゴミやホコリ等 の異物の付着量が増加し、これが巻装されるフィルムに転移すると共に、異物の 形状がフィルムに転写される。Even if the core can be reused, since the contact area between the film and the adhesive increases, the amount of the adhesive transferred to the film increases and the amount of contamination of the wound film also increases. become. In addition, if the core is reused, the exposed area of the adhesive increases and the amount of foreign matter such as dust and dust increases, which transfers to the film to be wound and the shape of the foreign matter is transferred to the film. It
【００１１】 上記のように、巻装されるフィルムに大なり、小なり影響を与えるので、 フィルムの内層部は、必要なロス分として処理されることとなる。 特に、上記のように、接着剤層を剥離シートで覆った巻芯は、磁気テープ用フ ィルムの巻芯としては表面の平滑性が得られず、使用に不向きである。As described above, since the wound film has a large or small influence, the inner layer portion of the film is treated as a necessary loss. In particular, as described above, the core having the adhesive layer covered with the release sheet cannot be used as the core of the magnetic tape film because the surface is not smooth.
【００１２】[0012]
本考案は、係る従来の欠点を克服するためになされたものであり、その目的は 、フィルム等の薄箔状物の巻き始め部分の位置決めを容易に、かつ、精度良く行 なえる薄箔状物用巻芯を提供することにある。 The present invention has been made in order to overcome the above-mentioned conventional drawbacks, and an object thereof is to make it possible to easily and accurately position a winding start portion of a thin foil-like object such as a film. It is to provide a winding core.
【００１３】[0013]
この目的を達成し得る本考案の薄箔状物用巻芯は、巻芯本体の面上に軸芯に沿 って帯状の接着剤層を設け、この接着剤層上に剥離シートを付着させた薄箔状物 用巻芯において、前記接着剤層を、着色した接着剤により形成したことを特徴と する。 The core for thin foil-like material of the present invention that can achieve this object is provided with a strip-shaped adhesive layer along the axis on the surface of the core body, and a release sheet is attached onto this adhesive layer. In the winding core for a thin foil, the adhesive layer is formed of a colored adhesive.
【００１４】 本考案に係る薄箔状物用巻芯は、この巻芯上に巻装される薄箔状物の両側部を 越えて感圧接着剤層が露出しないことが重要であり、そのために、感圧接着剤層 を薄箔状物の幅内に確実に収めることが必要である。 この感圧接着剤が流動化し易いものでない場合には、この感圧接着剤の塗布長 さを薄箔状物の幅よりも短く形成した構造でよいが、感圧接着剤が流動化し易い 状態のものである場合には、パラフィンやシリコン樹脂等の滑性又は剥離性のあ る材料の層を巻芯の両端に付着阻止部として形成する。この付着阻止部は、巻芯 本体の両端部に局部的に設けてもよいが、全周に設けてもよい。In the thin foil core according to the present invention, it is important that the pressure-sensitive adhesive layer is not exposed beyond both sides of the thin foil wound around the core. In addition, it is necessary to ensure that the pressure-sensitive adhesive layer fits within the width of the thin foil. If this pressure-sensitive adhesive is not easily fluidized, the coating length of this pressure-sensitive adhesive may be shorter than the width of the thin foil-like material, but the pressure-sensitive adhesive is easily fluidized. In the case of the above, a layer of a slippery or peelable material such as paraffin or silicone resin is formed on both ends of the winding core as adhesion preventing portions. The adhesion preventing portions may be provided locally on both ends of the core body, or may be provided on the entire circumference.
【００１５】 また、付着阻止部は、上記のように、塗布によって形成することができるが、 タックシール（付着防止性の貼着シート）を張り付けることによって形成しても よい。Further, the adhesion-preventing portion can be formed by coating as described above, but may be formed by sticking a tack seal (adhesion-preventing adhesive sheet).

以下、図面により本考案の実施例を説明する。 図１は、本考案の第１の実施例を示す巻芯の斜視図であり、巻芯本体１の表面 に感圧接着剤層２が軸線方向に一直線状に塗布されているが、この感圧接着剤層 ２は、巻芯本体１の端部１ａ，１ｂの周縁部分に非塗布部２ａ，２ｂが形成され ている。更に、この感圧接着剤層２の表面には、非塗布部２ａ，２ｂの一部又は 全部を覆うように剥離シート３が積層接着されている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a core according to a first embodiment of the present invention. A pressure-sensitive adhesive layer 2 is applied on the surface of a core body 1 in a straight line in the axial direction. The pressure-sensitive adhesive layer 2 has non-coated portions 2a and 2b formed on the peripheral edge portions of the end portions 1a and 1b of the core body 1. Further, a release sheet 3 is laminated and adhered on the surface of the pressure-sensitive adhesive layer 2 so as to cover a part or the whole of the non-coated portions 2a and 2b.
【００１７】 巻芯本体１は、基材に、(a) 紙を使用したもの、(b) 合成樹脂を使用したもの 、(c) 金属を使用したもの、(d) 前記材料の特徴を活かして複合化したものがあ る。 紙製の巻芯本体は、巻芯用紙管を主体としたもの、或いは、その表面に熱硬化 性合成樹脂を１回乃至数回塗布含浸させ、加熱状態で乾燥乃至硬化させ、次に、 その表面を切削研磨して表面の平滑性を向上させ、表面硬度と平滑性を改善した ものである。The core body 1 includes (a) paper as a base material, (b) a synthetic resin, (c) a metal, and (d) the characteristics of the above materials. There is a composite one. The core body made of paper is mainly composed of a core paper tube, or the surface thereof is coated and impregnated with a thermosetting synthetic resin once or several times, and then dried or cured in a heated state, and then, The surface is cut and polished to improve the surface smoothness and improve the surface hardness and smoothness.
【００１８】 合成樹脂製の巻芯本体は、合成樹脂製素管を使用し、その外表面を切削研磨に よって鏡面にし、その両端にフィルム巻取装置のチャック部に嵌装できるように 加工した真円度の高い合成樹脂管である。 金属製の巻芯本体は、鋼管の表面の平滑性を向上させた単一体のもの、また、 内層と表層、或いは内層と中間層と表層からなるもので、巻き取られたフィルム 等の薄箔状物に応じて、その表面に紙層、合成樹脂、或いは金属層を位置させて 複合化したものである。The synthetic resin core body is made of a synthetic resin tube, the outer surface of which is mirror-polished by cutting and polishing, and both ends of which are processed so that they can be fitted into the chuck part of the film winding device. It is a synthetic resin tube with high roundness. The metal core body is a single body with improved smoothness of the surface of the steel pipe, or consists of an inner layer and a surface layer, or an inner layer, an intermediate layer and a surface layer, and is a thin foil such as a wound film. Depending on the material, a paper layer, synthetic resin, or metal layer is placed on the surface to form a composite.
【００１９】 感圧接着剤層２としては、薄箔状物の貼着位置を判断し易くするために着色し た感圧性接着剤、合成樹脂製フィルムの場合は、アクリル系の接着剤が好ましく 、これらの接着剤を連続的、或いは間欠的な帯状に巻芯本体１の軸線に沿って塗 布する。 感圧接着剤層２の塗布幅は、巻芯本体１上に巻き取られる薄箔状物の両幅端部 よりはみ出さない幅、つまり、帯状の長さ（片側１０mm以内２mm以上）に規制す ることが必要である。 従って、通常の場合には、巻芯本体１の端部１ａ及び１ ｂの位置に感圧接着剤を塗布しない非塗布部２ａ，２ｂを形成する。また、この 感圧接着剤層２は、薄箔状物が巻き取られて巻き締め圧力が作用しても薄箔状物 の端部よりはみ出さないように配慮する。As the pressure-sensitive adhesive layer 2, a pressure-sensitive adhesive colored for facilitating the determination of the sticking position of the thin foil-like material, and in the case of a synthetic resin film, an acrylic adhesive is preferable. Then, these adhesives are applied in a continuous or intermittent strip shape along the axis of the winding core body 1. The coating width of the pressure-sensitive adhesive layer 2 is restricted to a width that does not protrude from both width ends of the thin foil-like material wound on the core body 1, that is, a strip-like length (within 10 mm on one side and 2 mm or more). It is necessary to. Therefore, in a normal case, the non-application portions 2a and 2b to which the pressure-sensitive adhesive is not applied are formed at the positions of the ends 1a and 1b of the core body 1. Further, the pressure-sensitive adhesive layer 2 is designed so that it does not stick out from the end of the thin foil-like material even when the thin foil-like material is wound up and the tightening pressure acts.
【００２０】 剥離シート３は、例えば、素材となる帯状紙の片面にパラフィン、オレフィン 系、シリコン系のワックスタイプ等の薄膜を形成したシート、又は剥離の際に感 圧接着剤から円滑に剥離する合成樹脂フィルム（例えば、ポリエチレンフィルム 、ポリプロピレンフィルム）であってもよい。 この剥離シート３は、感圧接着剤層２の幅を越えて貼着される必要があり、こ の感圧接着剤層２に押圧力が作用してもこの剥離シート３よりはみ出さない範囲 に寸法的に設計したものを貼着する必要がある。The release sheet 3 is, for example, a sheet in which a thin film of paraffin, olefin-based, silicon-based wax type or the like is formed on one surface of a band-shaped paper as a material, or it is smoothly released from a pressure-sensitive adhesive at the time of release It may be a synthetic resin film (for example, a polyethylene film or a polypropylene film). The release sheet 3 needs to be pasted over the width of the pressure-sensitive adhesive layer 2, and the pressure-sensitive adhesive layer 2 does not protrude from the release sheet 3 even when a pressing force is applied to the pressure-sensitive adhesive layer 2. It is necessary to attach the one dimensionally designed.
【００２１】 図２は、本考案の第２の実施例を示すものであり、巻芯本体１の端部周縁に接 着剤の付着阻止部２ｃ，２ｄを形成したものである。この付着阻止部２ｃ，２ｄ は、滑性又は離型性のある物質を塗布又は積層してものであって、ワックス類、 或いはシリコン樹脂類を使用することができる。付着阻止部２ｃ，２ｄの幅は、 通常の場合、約８〜１２mm程度、巻芯本体１の全周に形成しても良いが、感圧接 着剤層２の幅に対して充分な幅に形成する。FIG. 2 shows a second embodiment of the present invention, in which adhesive blocking parts 2c and 2d are formed on the peripheral edge of the core body 1. The adhesion preventing portions 2c and 2d are formed by coating or laminating a substance having a slipping property or a releasing property, and wax or silicon resin can be used. The width of the adhesion preventing portions 2c and 2d is normally about 8 to 12 mm and may be formed around the entire circumference of the core body 1, but the width is sufficient for the width of the pressure-sensitive adhesive layer 2. Form.
【００２２】 なお、当然のことであるが、巻芯本体１の両端に付着阻止部２ｃ，２ｄを設け た後、感圧接着剤層２を形成することにより、所定幅の感圧接着剤層２を形成す ることができる。また、図示されていないが、この実施例においても未使用状態 では、前記感圧接着剤層２の保護のために、その表面を覆って保護用の剥離シー ト３が積層されている。As a matter of course, the pressure-sensitive adhesive layer 2 having a predetermined width is formed by forming the pressure-sensitive adhesive layer 2 after providing the adhesion preventing portions 2c and 2d on both ends of the core body 1. 2 can be formed. Although not shown, also in this embodiment, in the unused state, a protective peeling sheet 3 is laminated to cover the surface of the pressure-sensitive adhesive layer 2 in order to protect the pressure-sensitive adhesive layer 2.
【００２３】 図３は、本考案の第３の実施例を示すものであり、非塗布部２ｅ，２ｆに係る ように薄箔状物を巻いた際に、感圧接着剤層２がはみ出さない幅内で、感圧接着 剤層２を間欠的に形成し、更に、その上に図示されていない保護用の剥離シート を積層させている。この構造の場合は、間欠的に形成した感圧接着剤層２毎に幅 の狭いフィルムＦを複数枚同時に巻装することができる。FIG. 3 shows a third embodiment of the present invention, in which the pressure-sensitive adhesive layer 2 protrudes when a thin foil-like material is wound around the non-coated portions 2e and 2f. The pressure-sensitive adhesive layer 2 is formed intermittently within a certain width, and a protective release sheet (not shown) is further laminated thereon. In the case of this structure, a plurality of narrow films F can be simultaneously wound for each pressure-sensitive adhesive layer 2 formed intermittently.
【００２４】 図４は、第４の実施例を示すものであって、巻芯本体１の両端部に円周方向に パラフィンやシリコン樹脂等の滑性又は離型性のある物質で付着阻止部２ｇ，２ ｈを形成し、これら両付着阻止部２ｇ，２ｈに連結するように巻芯本体１の軸線 方向に一直線状の感圧接着剤層２を形成し、その上に剥離シート３を感圧接着剤 層２を越えた長さに付着する。FIG. 4 shows a fourth embodiment of the present invention, in which both ends of the core body 1 are circumferentially circumferentially made of a substance such as paraffin or silicon resin having a slipping property or a releasing property so as to prevent adhesion of the adhesion preventing part. 2g, 2h are formed, a pressure-sensitive adhesive layer 2 is formed in a straight line in the axial direction of the core body 1 so as to be connected to both the adhesion preventing portions 2g, 2h, and the release sheet 3 is applied thereon. Pressure Adhesive Adheres to length beyond layer 2.
【００２５】 なお、付着阻止部２ｇ，２ｈの幅は、フィルムＦの両端部に乗り、感圧接着剤 層２がこのフィルムＦに付着しない幅とする。 図５は、図４に示す巻芯本体１上にフィルムＦの端部を感圧接着剤層２を介し て接着し、このフィルムＦの両端部ｆ1 ，ｆ2 を付着阻止部２ｇ，２ｈ上に位置 させた状態を示しており、フィルムＦの両端部ｆ1 ，ｆ2 には、感圧接着剤が付 着しないようになっている。The widths of the adhesion preventing portions 2g and 2h are such that the pressure sensitive adhesive layer 2 does not adhere to the film F by riding on both ends of the film F. In FIG. 5, the ends of the film F are adhered to the core body 1 shown in FIG. 4 via the pressure-sensitive adhesive layer 2, and the both ends f 1 and f 2 of the film F are adhered to the adhesion preventing parts 2g and 2h. The upper position is shown, and the pressure-sensitive adhesive is not attached to both ends f 1 and f 2 of the film F.
