Description

この発明は、巻き材料の製造ライン巻き上げ又は、スリッター時の巻き材料の中心コア部品分野である。 The present invention is in the field of central core parts of a winding material during winding or slitting of a winding material.

図６は、従来の実施例図であるが、巻き材料端を両面テープ又は、片面粘着テープＥで止めていて、巻き始めの段差６が非情に高くなっているが其の上に次の材料が巻かれ段差６がそのまま、何周も巻き段差模様が残り、巻き芯側が使用できなくなり不経済である。 FIG. 6 is a diagram of a conventional embodiment, but the end of the winding material is stopped with a double-sided tape or a single-sided adhesive tape E, and the step 6 at the beginning of winding is extremely high. Is wound, and the step 6 remains as it is, and the winding step pattern remains many times, and the winding core side cannot be used, which is uneconomical.

巻き材料Ｂは、原反材料の中でも厚みのばらつきが有る為、スリッターした時、列により固い巻き、緩い巻きができ固い巻き材は巻き芯コア１の表面に巻き圧力が発生し、巻き段差痕６ａ、が付いてしまう。緩すぎると巻き芯コア１が外れてしまいより不良材料が出来てしまう。巻きの強さを分割する為、巻き取り軸を２箇所で巻き解消しようとしているが、巻き段差６の解消ができていないため巻き段差痕６ａが巻き材料Ｂについてしまう。 Since the winding material B has a variation in thickness among the raw material, when the slitting is performed, the winding material is wound tightly or loosely by the row, and the winding material generates a winding pressure on the surface of the core core 1, and winding step traces are generated. 6a is attached. If it is too loose, the core core 1 will come off and a poorer material will be produced. In order to divide the strength of the winding, the winding shaft is attempted to be removed at two places. However, since the winding step 6 has not been eliminated, the winding step mark 6a is left on the winding material B.

巻き芯コア１に巻き材料Ｂの厚み分段差をつけて巻く仕様もあるが、巻き材料Ｂの厚みの種類が多く、専用の厚みのコア１を使用すれば良いが、コア１の在庫種類が増えかえって手間がかかるうえ不経済になり現実で的でない。又段差を大きくすると、巻上げ時中心ぶれを起し、折れ、しわ等が入り易く綺麗に巻き上げが出来なく、別の不良が発生してしまう。 There is also a specification in which the winding core B is wound with a step corresponding to the thickness of the winding material B, but there are many types of thickness of the winding material B, and it is sufficient to use the core 1 having a dedicated thickness. It takes more time and effort, and it becomes uneconomical and unrealistic. Also, if the level difference is increased, center wobbling will occur at the time of winding, and folding, wrinkles, etc. will easily occur, and it will not be possible to wind up beautifully, resulting in another defect.

巻上げ時に少しの異物が混入しても、巻き材料に打痕として残り其の部分が使用不可となり使用できない。 Even if a small amount of foreign matter is mixed during winding, the remaining part remains unusable on the wound material and cannot be used.

巻き芯コア１の回りに緩衝材を１周巻付けているが、ゴムのように伸びる材料であればそれに沿って巻けるが、樹脂シートのように伸びない材料の場合巻き材料が何重にも巻かれると緩衝材の所に巻き圧力が集中し巻き材料が梅干状態になりよけい小さいしわが入り易く巻き芯コア１に向かない。 A cushioning material is wound around the core core 1 once, but if it is a material that stretches like rubber, it can be wound along it, but if it is a material that does not stretch like a resin sheet, the winding material is layered many times When it is wound, the winding pressure is concentrated on the buffer material, and the wound material is in an umeboshi state.

巻き材料Ｂに巻き段差痕、しわ、打痕を入れないで巻き上げができ、巻き材料Ｂを巻き芯コアの最直前まで使用でき材料不良を無くする事が課題である。 The winding material B can be rolled up without making a winding step mark, wrinkle, or dent mark, and the problem is that the winding material B can be used up to the point immediately before the core core to eliminate material defects.

以上の課題を解決するために、巻き芯コア１に材料固定テープ溝部５を形成し、その溝に段差吸収固定テープＣを貼りその上に巻き材料Ｂの端部Ａを止める。巻き材料Ｂの端部Ａのみが沈み、巻き段差６を解消しようとするものである。又、巻き材料の端をコアの中に入れて、材料の段差を無くし巻き段差を入れなくする。又、巻き芯コア１の両サイドを高くし、巻き芯枕部３を設けることで、巻き材料端止め用固定片面テープＥもしくは、巻き材料端止め用両面テープＦの段差を付けなく、異物が混入しても、空気層で緩和でき、巻き材料に影響しない。 In order to solve the above problems, the material fixing tape groove 5 is formed in the winding core 1, and the step absorption fixing tape C is applied to the groove, and the end A of the winding material B is stopped thereon. Only the end A of the winding material B sinks and the winding step 6 is to be eliminated. In addition, the end of the winding material is put into the core to eliminate the material step and to prevent the winding step. Further, by providing both sides of the core core 1 and providing the core pillow 3, foreign matter can be removed without forming a step of the fixed single-sided tape E for winding material end-stopping or the double-sided tape F for winding material end-stopping. Even if mixed, it can be relaxed by the air layer and does not affect the wound material.

本考案の巻き芯コア１に替える事で、しわ、段差模様６、打根が解消出来巻き材料Ｂを最後まで使える為材料のロスが無く大変経済的であり、材料在庫の管理もでき残りが全良品であれば計算ができ不必要な材料を発注する必要も無く、コスト低減ができる考案である。   By switching to the core core 1 of the present invention, wrinkles, stepped patterns 6 and roots can be eliminated, and the wound material B can be used to the end, so there is no material loss and the material inventory can be managed. It is a device that can be calculated for all non-defective products, and it is not necessary to place an order for unnecessary materials, thereby reducing costs.

図１は、本考案側面図であるが、芯コア１の上に順次巻き材料Ｂを巻き上げるが、巻き上げ材料の端部Ａが膨れてしまう為、巻き上げ材料の端部Ａを低くする為材料固定テープ溝５を成形し、その溝に段差吸収固定テープＣを貼り巻き材料端Ａ側を図２に示す拡大側面図のカッター刃８で材料固定溝部５に添って切り落とせば溝よりはみだすことが無い為、巻き材料端部Ａは次に巻かれる材料Ｂで材料の厚み分沈み端の膨れが解消でき、巻き材料段差部６もできない。したがって、巻き材料Ｂを何重に巻いても巻き段差６は入らなく、巻き材料Ｂを最後まで使用することができるため、大変経済的であり大変有効な発明といえる。 FIG. 1 is a side view of the present invention. The winding material B is wound up on the core core 1 in sequence, but the end A of the winding material swells, so that the material fixing is performed to lower the end A of the winding material. When the tape groove 5 is formed, the step absorption fixing tape C is applied to the groove, and the material end A side is cut off along the material fixing groove portion 5 with the cutter blade 8 in the enlarged side view shown in FIG. Therefore, the winding material end A can be eliminated by the material B to be wound next, and the swelling of the sinking end can be eliminated by the thickness of the material, and the winding material stepped portion 6 cannot be formed. Therefore, no matter how many times the winding material B is wound, the winding step 6 does not enter, and the winding material B can be used to the end, so that it can be said to be a very economical and very effective invention.

図２は、部分拡大図であるが、巻き材料Ｂが無い時は段差吸収固定テープＣがコア１より少し高く（左図）であり、材料端部Ａを段差吸収固定テープＣに付け巻き圧により材料端部Ａが弾力部Ｄに吸収され巻ける（右図）巻き材料Ｂの端部分Ａのみが沈み巻き材料Ｂに巻き段差、しわなど発生させない。 FIG. 2 is a partially enlarged view, but when there is no winding material B, the step absorption fixing tape C is slightly higher than the core 1 (left figure), and the material end A is attached to the step absorption fixing tape C and the winding pressure is increased. As a result, the material end A is absorbed and wound by the elastic portion D (right figure). Only the end portion A of the wound material B sinks, and no winding step or wrinkle is generated on the wound material B.

図３で示し巻き芯コア１に端入れ溝７とテープ固定溝部５を形成し、巻き始め巻き材料Ｂを固定する為の段差吸収固定テープＣを貼り、巻き取り材料端部Ａを巻き取り材料端入れ溝部７に入れ段差吸収固定テープＣで固定して巻き上げると、巻き段差部６が付かず段差模様６ａがつかない。材料の厚みにより、段差吸収固定テープＣの厚み調整も出来る。専用のコアを作り１周目と２周目の段差をつけても良いが、巻き材料厚みの種類が有る為、材料固定テープ溝部５に少し勾配を付けるとより効果が有り、２周目が重なっても必要以上の材料端段差６は吸収する。段差吸収固定テープＣを付ける事で巻き芯コア１の種類も最小限に出来る。 The end insertion groove 7 and the tape fixing groove portion 5 are formed in the winding core core 1 shown in FIG. 3, and the step absorption fixing tape C for fixing the winding material B at the beginning of the winding is applied, and the winding material end portion A is taken up as the winding material. When it is inserted into the end insertion groove portion 7 and fixed with the step absorption fixing tape C and rolled up, the winding step portion 6 is not attached and the step pattern 6a is not attached. The thickness of the step absorption fixing tape C can be adjusted depending on the thickness of the material. It is possible to make a dedicated core and make a step between the first and second laps, but because there are different types of winding material thickness, it is more effective to add a slight gradient to the material fixing tape groove 5. Even if they overlap, the material edge step 6 more than necessary is absorbed. By attaching the step absorption fixing tape C, the type of the core 1 can be minimized.

図４に示す巻き芯コアの拡大側面図であるが、巻き材料端Ａを巻き取り材料Ｂ端入れ溝部７に入れ、段差吸収固定テープＣで巻き材料Ｂを止め、巻き上げるが、巻き上げ材料Ｂをつけるまでは、巻き芯コアの表面より高くしてあるが、巻き材料Ｂを固定して２周目が巻かれた時、その材料に押えられ膨らんだ部分のみが段差吸収固定テープＣに吸収され段差が無くなる。その上に何重に巻いても巻き段差模様はつかなく、巻き芯コアの表面まで使え大変経済的で有り大変有効な発明である。 Although it is an enlarged side view of the winding core core shown in FIG. 4, the winding material end A is put into the winding material B end insertion groove portion 7, and the winding material B is stopped and rolled up by the step absorption fixing tape C. Until it is attached, it is higher than the surface of the core core, but when the winding material B is fixed and the second turn is wound, only the swollen portion pressed by the material is absorbed by the step absorption fixing tape C. There is no step. Even if it is wound several times on top of it, there is no winding step pattern, it can be used up to the surface of the core core, and it is a very economical and very effective invention.

図５は、本考案側面図であるが、両サイドを樹脂コア１自体で成型して高くするか、はめ込み式付属品を付け、巻き取り材料Ｂを巻き芯コア１に巻いた時、空気層４ができ巻きの圧力でつく打根、段差模様６、しわを緩和できる為最後まで巻き取り材料Ｂが使用でき経済的である。図１図３の考案に図５の組み合わせも可能で、より効果的である。 FIG. 5 is a side view of the present invention, in which both sides are molded with the resin core 1 itself to make it higher, or a fitting accessory is attached, and when the winding material B is wound around the core core 1, 4 can be used, and the winding material B can be used to the end because it can relieve the root, the step pattern 6 and the wrinkle that are formed by the winding pressure. 1 and 3 can be combined with FIG. 5, which is more effective.

両サイド高くする手法としてもう一つは、片面粘着材料を使用する手法もあるが幅広く対応しやすく、粘着層の種類も多く再利用もしやすい。巻かれる材料Ｂの材料と止めるテープＥの厚み以上にすれば段差模様６は入らない。例題として巻き材料が５０ミクロンの場合巻き材料端止めようテープＥが６０ミクロンの場合、片面粘着材料を１１０ミクロン以上の厚みにすれば段差模様６は付かなく効果的である。 Another method for increasing both sides is to use a single-sided adhesive material, but it is easy to deal with a wide range, and there are many types of adhesive layers that are easy to reuse. If the thickness is equal to or larger than the material of the material B to be wound and the thickness of the tape E to be stopped, the step pattern 6 does not enter. As an example, when the winding material is 50 microns, when the tape E is 60 microns so as to stop the winding material, if the single-sided adhesive material has a thickness of 110 microns or more, the step pattern 6 is not attached and is effective.
