Description

本発明は、レザーシートなどの軟質シートをロール状に巻き取るために用いる軟質シート巻き取り用円筒体に関するものである。   The present invention relates to a soft sheet winding cylindrical body used for winding a soft sheet such as a leather sheet into a roll.

従来、ロール状記録用紙用紙管として、図５に示すように、紙管１の外周に発泡スチレン等のへこみ易い材料からなる緩衝材３が巻かれた構成を有し、より効果を高めるために、緩衝材３に段差、溝、スリット等が設けられたものが知られている。緩衝材３を介して用紙２を巻くことにより、用紙２の先端部２ａは巻き取りのテンションにより緩衝材に食い込み、２巻き目以降のロール用紙の巻き始め部分の段差を減らし、用紙２の変形を押さえるようにするものである。   Conventionally, as a rolled recording paper tube, as shown in FIG. 5, the outer periphery of the paper tube 1 has a configuration in which a cushioning material 3 made of an easily dented material such as foamed styrene is wound. In addition, the buffer material 3 provided with a step, a groove, a slit and the like is known. By winding the paper 2 through the buffer material 3, the leading end 2 a of the paper 2 bites into the buffer material by the winding tension, reducing the level difference at the winding start portion of the roll paper after the second roll, and deforming the paper 2. It is intended to hold down.

かかる紙管を用いてロール状記録用紙を巻き取る場合には、ロール状記録用紙が比較的硬質なため段差跡が残り難くいと考えられるが、レザーシートなどの比較的軟質のシート材を巻き取る場合は、段差跡が残ってしまう。   When the roll-shaped recording paper is wound using such a paper tube, it is considered that the trace of the step is unlikely to remain because the roll-shaped recording paper is relatively hard. However, a relatively soft sheet material such as a leather sheet is wound. In that case, a step mark will remain.

特開２０００−３１８９３０号公報JP 2000-318930 A

そこで、本発明の目的は、比較的軟質のシートを巻き取った場合でも段差跡が残り難い軟質シート巻き取り用円筒体を提供することにある。   Accordingly, an object of the present invention is to provide a soft sheet winding cylindrical body in which a step mark hardly remains even when a relatively soft sheet is wound.

上記課題を解決するため、本発明による軟質シート巻き取り用円筒体は、軟質シートをロール状に巻き取る円筒体であって、円筒体本体の外周に補助シートを巻き付けてなり、該補助シートは少なくともその終端側が終端に向かって次第に厚さが薄くなるテーパー状に形成され、補助シートの終端部とその手前側を前記円筒体本体側と接着しない非接着部としたこと、を特徴としている。
ここで、補助シートはその始端側が始端に向かって次第に厚さが薄くなるテーパー状に形成するとよい。
また、補助シートは円筒体本体一周分よりも多く巻くとよい。 In order to solve the above-mentioned problems, a cylindrical body for winding a soft sheet according to the present invention is a cylindrical body that winds a soft sheet into a roll shape, and is formed by winding an auxiliary sheet around the outer periphery of the cylindrical body. It is characterized in that at least the end side thereof is formed in a tapered shape that gradually decreases in thickness toward the end, and the end portion of the auxiliary sheet and the front side thereof are non-adhered portions that are not bonded to the cylindrical body side.
Here, the auxiliary sheet may be formed in a taper shape in which the starting end side becomes gradually thinner toward the starting end.
Further, the auxiliary sheet may be wound more than a round of the cylindrical body.

本発明による軟質シート巻き取り用円筒体によれば、円筒体本体の外周に巻き付けた補助シートは少なくともその終端側が終端に向かって次第に厚さが薄くなるテーパー状に形成されてなるので、軟質シートの始端を補助シートで挟んで巻き取っていくと、軟質シートの巻き始めの始端部の段差は補助シートによってカバーされ、補助シートの終端部では段差はなく、巻き戻した軟質シートに段差跡はほとんど残らない。
補助シートの始端側も始端に向かって次第に厚さが薄くなるテーパー状に形成すれば、補助シートの始端部での段差もなくなる。
また、補助シートを円筒体本体一周分よりも多く巻けば、補助シートの始端部で粘着材が多少はみ出しても、２巻き目の補助シートでカバーされるため、巻き取り対象物たる軟質シートに粘着材が付着することがない。また、補助シートの始端部をテーパー加工していない場合でも、２巻き目の補助シートが補助シートの始端部の段差をカバーすることができる。 According to the cylindrical body for winding up the soft sheet according to the present invention, the auxiliary sheet wound around the outer periphery of the cylindrical body is formed in a tapered shape in which at least the end side thereof gradually decreases in thickness toward the end. When the roll is wound with the auxiliary sheet sandwiched between the auxiliary sheet, the step at the beginning of the soft sheet is covered by the auxiliary sheet, and there is no level difference at the terminal end of the auxiliary sheet. Little remains.
If the starting end side of the auxiliary sheet is also formed in a tapered shape whose thickness gradually decreases toward the starting end, there is no step at the starting end portion of the auxiliary sheet.
In addition, if the auxiliary sheet is wound more than the entire circumference of the cylindrical body, even if the adhesive material protrudes somewhat at the starting end of the auxiliary sheet, it is covered with the second auxiliary sheet, so that the soft sheet as the winding object Adhesive material does not adhere. Even when the starting end portion of the auxiliary sheet is not tapered, the second auxiliary sheet can cover the step at the starting end portion of the auxiliary sheet.

以下、本発明を実施するための形態を図面に基づいて具体的に説明する。図１に示す本発明の第１実施例による軟質シート巻き取り用円筒体１０は、円筒体本体１１の外周に補助シート１２を１周と１／４周ほど巻き付けたもので、該補助シート１２はその終端側１２ａが終端に向かって次第に厚さが薄くなるテーパー状に形成（テーパー加工）してある。
補助シート１２は、円筒体本体１１の外周に両面粘着テープ１３で接着して巻き付けてある。接着箇所は、補助シート１２の始端部１２ｂと、１周目と２周目の重なり部との２箇所としてある。そして、補助シート１２の終端部１２ａとその手前側の部分（１２ｃ）は非接着部とし、巻き取り対象物たる軟質シート１４の巻き始め端部（始端部）１４ａを挟み込むための挟持部（１２ｃ）としてある。
図１においては、補助シート１２の始端１２ｂにはその厚さ分の段差があるが、２巻き目の補助シート１２によって該段差部分がカバーされるので、該部分での段差は殆ど残らない。
図３に示した第２実施例による軟質シート巻き取り用円筒体１０では、始端側１２ｂにもテーパー加工を施した補助シート１２を用いている。 Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings. A flexible sheet winding cylindrical body 10 according to the first embodiment of the present invention shown in FIG. 1 is obtained by winding an auxiliary sheet 12 around the outer periphery of a cylindrical body 11 about 1 and 1/4 turn. The terminal side 12a is formed into a taper shape (tapering) that gradually decreases in thickness toward the terminal end.
The auxiliary sheet 12 is wound around the outer periphery of the cylindrical body 11 with a double-sided adhesive tape 13. There are two bonding locations, the starting end portion 12b of the auxiliary sheet 12 and the overlapping portion of the first and second rounds. And the terminal part 12a and the front part (12c) of the auxiliary sheet 12 are non-adhesive parts, and a sandwiching part (12c) for sandwiching the winding start end part (starting end part) 14a of the soft sheet 14 to be wound up. ).
In FIG. 1, there is a step corresponding to the thickness of the starting end 12 b of the auxiliary sheet 12, but since the step portion is covered by the second roll of auxiliary sheet 12, almost no step remains in the portion.
In the flexible sheet winding cylindrical body 10 according to the second embodiment shown in FIG. 3, the auxiliary sheet 12 that is also tapered on the start end side 12 b is used.

補助シート１２は円筒体本体１１一周分より多く巻くようにするのが好ましい。補助シート１２の始端部１２ｂで粘着材１３が多少はみ出した場合でも、２巻き目の補助シート１２でカバーするようにして、巻き取り対象物たる軟質シート１４に粘着材１３が付着しないようにする。また、補助シート１２の始端部１２ｂをテーパー加工していない場合でも（図１）、２巻き目の補助シート１２が補助シート１２の始端部１２ｂの段差をカバーできるようにする。
なお、始端側１２ｂにもテーパー加工を施した補助シート１２では、一周分より少なくても、段差解消が可能である。 The auxiliary sheet 12 is preferably wound more than one round of the cylindrical body 11. Even when the adhesive material 13 protrudes somewhat at the start end portion 12b of the auxiliary sheet 12, it is covered with the second roll of auxiliary sheet 12 so that the adhesive material 13 does not adhere to the soft sheet 14 that is the winding object. . Further, even when the starting end portion 12b of the auxiliary sheet 12 is not tapered (FIG. 1), the second winding auxiliary sheet 12 can cover the step of the starting end portion 12b of the auxiliary sheet 12.
Note that the auxiliary sheet 12 that is also tapered on the start end side 12b can eliminate the step even if it is less than one round.

円筒体本体１１は、紙管原紙により形成した紙管でもよく、プラスチック製円筒体でもよい。直径は５０〜１００ｍｍ程度である。
補助シート１２は比較的硬質の紙材（紙管原紙、ライナー紙など）が好ましいが、比較的硬質のプラスチックシート材でもよい。厚さは０．５〜１ｍｍ程度が好ましい。
端部に向かって次第に厚さが薄くなるように形成するテーパー加工（スカイバー加工）は、補助シート１２の端部１２ａ，１２ｂをサンドペーパーで研削することにより加工できるが、他の方法によりテーパー加工を施してもよい。テーパー加工を施す幅（Ｗ）は１０〜２０ｍｍ程度とする。
巻き取り用円筒体１０に巻き取られるシート１４は、軟質のシート、例えば、レザーシート等が挙げられ、厚さは、０．３〜２ｍｍ程度のものを巻き取り対象としている。 The cylindrical body 11 may be a paper tube formed from a paper tube base paper or a plastic cylindrical body. The diameter is about 50 to 100 mm.
The auxiliary sheet 12 is preferably a relatively hard paper material (paper tube base paper, liner paper, etc.), but may be a relatively hard plastic sheet material. The thickness is preferably about 0.5 to 1 mm.
The taper processing (sky bar processing) formed so that the thickness gradually decreases toward the end portion can be processed by grinding the end portions 12a and 12b of the auxiliary sheet 12 with sandpaper, but the taper processing is performed by other methods. May be applied. The width (W) for taper processing is about 10 to 20 mm.
Examples of the sheet 14 wound around the winding cylindrical body 10 include a soft sheet, for example, a leather sheet, and the thickness is about 0.3 to 2 mm.

かかる構造の軟質シート巻き取り用円筒体１０を用いて軟質シート１４を巻き取るには、軟質シート１４の始端１４ａを補助シート１２の終端部１２ａとその手前側の挟持部１２ｃに挟みこみ、巻き取っていけばよい。このとき、軟質シート１４の始端部１４ａの段差は、巻き取られるシート１４が軟質であり、補助シート１２によってカバーされるため、軟質シート１４の始端部で段差跡が残ることはない。   In order to wind up the soft sheet 14 using the soft sheet winding cylindrical body 10 having such a structure, the starting end 14a of the soft sheet 14 is sandwiched between the terminal end portion 12a of the auxiliary sheet 12 and the clamping portion 12c on the near side thereof, and wound. Take it. At this time, the step at the start end portion 14 a of the soft sheet 14 is not covered with a step mark at the start end portion of the soft sheet 14 because the wound sheet 14 is soft and covered by the auxiliary sheet 12.

円筒体の直径５０ｍｍ、補助シート１２として厚さ０．５ｍｍの紙管原紙を用いた図３に示す構造の軟質シート巻き取り用円筒体１０に、厚さ１ｍｍの軟質シート（塩化ビニル樹脂製シート）１４を巻き取り、しかる後巻き戻したところ、巻き戻した軟質シート１４に段差跡は見られず、巻き取った軟質シート１４の全てが使用可能で、無駄な部分を生ずることがなかった。
また、始端部１２ｂにテーパー加工を施していない補助シート１２を用いた他は上記と同様の図１に示す構造の軟質シート巻き取り用円筒体１０に、厚さ１ｍｍの軟質シート（塩化ビニル樹脂製シート）１４を巻き取り、しかる後巻き戻したところ、最初の数巻分だけ、補助シート１２の始端部１２ｂで僅かに段差跡が残った程度であった。 A soft sheet (vinyl chloride resin sheet) having a thickness of 1 mm is formed on the soft sheet winding cylinder 10 having the structure shown in FIG. 3 using a paper tube base paper having a diameter of 50 mm and a thickness of 0.5 mm as the auxiliary sheet 12. ) 14 was wound up and then rewound. As a result, no traces of steps were observed in the rewound soft sheet 14, and all of the rewound soft sheet 14 could be used, and no useless part was produced.
Further, a soft sheet (vinyl chloride resin) having a thickness of 1 mm is formed on a soft sheet winding cylindrical body 10 having the structure shown in FIG. 1 except that an auxiliary sheet 12 that is not tapered at the start end portion 12b is used. Sheet 14) was wound up and then rewound. As a result, only a few steps were left on the starting end portion 12b of the auxiliary sheet 12 for the first several turns.
