以下本発明を実施するための最良の形態を示しながら本発明をさらに詳説する。
本発明によって、紙幅及び紙管長が望ましくは１１４±２ｍｍ、あるいは短くとも最低で１００ｍｍ、好ましくは下限を１０５ｍｍとする長さ範囲内のトイレットペーパーロールであって、紙管１の全周で、かつ、図４の（ａ）のように、全長に糊を介してトイレットペーパーが巻き取られているトイレットペーパーロールが提供される。この場合、ＪＩＳ Ｐ ４５０１（１９９３）に規定されものが好適に使用される。
Hereinafter, the present invention will be described in more detail while showing the best mode for carrying out the present invention.
According to the present invention, a toilet paper roll having a paper width and a paper tube length of desirably 114 ± 2 mm, or at least a minimum of 100 mm, preferably a lower limit of 105 mm, on the entire circumference of the paper tube 1, and As shown in FIG. 4A, a toilet paper roll is provided in which the toilet paper is wound around the entire length via glue. In this case, those specified in JIS P 4501 (1993) are preferably used.
また、図４の（ａ）のように、軸方向中央部の紙管１の長さＬの４０〜６５％の長さ範囲を非塗布部Ｚとして、紙管１の両端部全体部分に、糊を介してトイレットペーパーが巻き取られているトイレットペーパーロールも提供される。 Moreover, as shown to (a) of FIG. 4, the length range of 40 to 65% of the length L of the paper tube 1 of the axial direction center part is made into the non-application part Z, and the both ends of the paper tube 1 whole part part, A toilet paper roll is also provided in which the toilet paper is wound up via glue.
かかるトイレットペーパーロールの製造例を図５及び図６によって説明すると、長尺紙管１０が外部から供給され、マンドレルシャフト１２の外部に挿嵌される。マンドレルシャフト１２の両端は、図５の紙面を貫く方向に間隔を置いてそれぞれ配設された無端チェーン１４，１４間に固定のチャック１６，１６に保持された状態で、矢印方向（図５の反時計方向）に移動する。したがって、マンドレルシャフト１２に保持された長尺紙管１０も移動され、所定の位置に設けられた糊塗布装置１８によりピックアップされた糊Ａが、長尺紙管１０が周方向に転動する過程で、その外面に塗布される。 A manufacturing example of such a toilet paper roll will be described with reference to FIGS. 5 and 6. A long paper tube 10 is supplied from the outside and is inserted into the outside of the mandrel shaft 12. Both ends of the mandrel shaft 12 are held in fixed chucks 16 and 16 between endless chains 14 and 14 arranged at intervals in a direction penetrating the paper surface of FIG. Move counterclockwise. Accordingly, the long paper tube 10 held by the mandrel shaft 12 is also moved, and the paste A picked up by the glue applying device 18 provided at a predetermined position rolls the long paper tube 10 in the circumferential direction. And applied to the outer surface.
糊Ａが塗布された長尺紙管１０は、巻取り手段の部位に移動される。巻取り手段は、幅広ペーパーウェブＷ０を案内するワインディングロール２０と、これと対向する回転無端ベルト２２と、長尺紙管１０に幅広ペーパーウェブＷ０が巻き付けられたロール状物を、周方向に前記回転無端ベルト２０により回転させて巻取りを行うものである。 The long paper tube 10 to which the paste A is applied is moved to the site of the winding means. The winding means includes a winding roll 20 for guiding the wide paper web W0, a rotating endless belt 22 opposed to the winding roll 20, and a roll-like product in which the wide paper web W0 is wound around the long paper tube 10 in the circumferential direction. The rotary endless belt 20 is rotated for winding.
回転無端ベルト２２は、駆動側プーリ２２Ａと従動側プーリ２２Ｂとにベルト２２Ｃが巻き掛けられたもので、駆動側プーリ２２Ａの軸心とワインディングロール２０の軸心とを繋ぐほぼ線上に、糊Ａを付着させた長尺紙管２０が入り込むと、本格的に回転無端ベルト２２による回転に伴って従動転動が開始する。図５では、長尺紙管２０が入り込む間隙を説明のために誇張して図示してあるが、実際は、前記軸心間を繋ぐ線上において、長尺紙管２０はベルト２２Ｃ及びワインディングロール２０を巡る幅広ペーパーウェブＷ０に接触する程度の間隙である。 The rotating endless belt 22 is configured by a belt 22C wound around a driving pulley 22A and a driven pulley 22B. When the long paper tube 20 to which is attached enters, the driven rolling starts with the rotation of the rotating endless belt 22 in earnest. In FIG. 5, the gap into which the long paper tube 20 enters is exaggerated for the sake of explanation, but in actuality, the long paper tube 20 has a belt 22 </ b> C and a winding roll 20 on the line connecting the axes. It is a gap | interval of the grade which contacts the wide wide paper web W0.
本発明においては、たとえば、駆動側プーリ２２Ａと同軸に本発明の案内手段として助走円盤３０が設けられている。この助走円盤３０は、後述する長尺紙管２０の未塗布部分Ｚ内に対応した位置に配置された回転円盤であり、助走円盤３０の直径は（駆動側プーリ２２Ａの直径＋２×回転無端ベルト２２Ｃ厚）より大きいものである。したがって、図５のように、助走円盤３０の外周はベルト２２Ｃよりごく僅か、たとえば１〜３ｍｍ程度、駆動側プーリ２２Ａの半径方向に関し外方に突出している。 In the present invention, for example, a running disk 30 is provided coaxially with the driving pulley 22A as the guiding means of the present invention. The running disk 30 is a rotating disk disposed at a position corresponding to an uncoated portion Z of the long paper tube 20 described later, and the diameter of the running disk 30 is (the diameter of the driving pulley 22A + 2 × the rotating endless belt). 22C thickness). Therefore, as shown in FIG. 5, the outer periphery of the running disk 30 protrudes outwardly with respect to the radial direction of the driving pulley 22 </ b> A, only slightly from the belt 22 </ b> C, for example, about 1 to 3 mm.
他方、糊塗布装置１８において、図６に明示のように、糊Ａは各助走円盤３０の厚みより大きい（長尺紙管２０の長手方向長さが長い）非塗布部分Ｚをもって、長尺紙管２０の全周に塗布する。 On the other hand, in the glue application device 18, as clearly shown in FIG. 6, the glue A has a non-application part Z larger than the thickness of each run-off disk 30 (the length in the longitudinal direction of the long paper tube 20) is long. Apply to the entire circumference of the tube 20.
このように構成された設備によれば、糊Ａが塗布された長尺紙管１０が、無端チェーン１４，１４の移動に伴って、巻取り手段の部位に移動されると、まず、長尺紙管１０は、助走円盤３０の外面に当接し、さらに移動する過程で、助走円盤３０の外面に押されるので、図５の矢印で示すように、ワインディングロール２０を巡る幅広ペーパーウェブＷ０側に移動する。したがって、糊Ａを介して幅広ペーパーウェブＷ０が長尺紙管１０外面に付着し、１巻き以上転動が開始する。続いて、前記軸心間を繋ぐ線上に移動すると、本格的に回転無端ベルト２２による回転に対し従動転動が開始する。この従動転動に伴って、ロール状物は、直径の拡大に伴って下方へ移動する。最終的に所定の長さまで巻取りが終了した時点でカッター２４により幅広ペーパーウェブＷ０が切断される。 According to the equipment configured in this way, when the long paper tube 10 to which the paste A is applied is moved to the portion of the winding means as the endless chains 14 and 14 are moved, first, the long paper tube 10 Since the paper tube 10 abuts on the outer surface of the running disk 30 and is further moved, the paper tube 10 is pushed by the outer surface of the running disk 30, so that the paper tube 10 moves toward the wide paper web W 0 around the winding roll 20 as shown by the arrows in FIG. Moving. Therefore, the wide paper web W0 adheres to the outer surface of the long paper tube 10 via the glue A, and rolling of one or more turns starts. Subsequently, when it moves on a line connecting the shaft centers, the driven rolling starts in earnest with respect to the rotation by the rotating endless belt 22. Along with this driven rolling, the roll-like object moves downward as the diameter increases. Finally, the wide paper web W0 is cut by the cutter 24 when the winding is finished to a predetermined length.
その後、マンドレルシャフト１２から幅広ペーパーウェブＷ０を巻き取った長尺紙管１０が抜き出され、当該設備から排出され、スリティング手段としてのスリッター（図示せず）により、幅広ペーパーウェブＷ０を巻き取った長尺紙管１０は、裁断され、短幅の単位トイレットペーパーロールに分割される。この場合、図６に示すように、非塗布部Ｚが中央となる寸法関係でスリットを行う。分割された単位トイレットペーパーロールが図４に示されている。 Thereafter, the long paper tube 10 on which the wide paper web W0 is wound up is extracted from the mandrel shaft 12, discharged from the equipment, and wound on the wide paper web W0 by a slitter (not shown) as a slitting means. The long paper tube 10 is cut and divided into short unit toilet paper rolls. In this case, as shown in FIG. 6, slitting is performed in a dimensional relationship where the non-application portion Z is in the center. A split unit toilet paper roll is shown in FIG.
なお、本発明の案内手段として、上記例では、助走円盤３０を使用したが、長尺紙管１０の本格的転動に先立ってワインディングロール２０側に移動させればよいから、たとえば、マンドレルシャフト１２をワインディングロール２０側に移動させる案内ガイドなどでもよい。この場合、案内ガイドをマンドレルシャフト１２の両端部に設ければ、長尺紙管１０外面の全長及び全周にわたって糊Ａを塗布することができる。したがって、すべてにおいて非塗布部分のないトイレットペーパーロール群を生産できる。 As the guiding means of the present invention, the running disk 30 is used in the above example. However, since the long paper tube 10 may be moved to the winding roll 20 side prior to full-scale rolling, for example, a mandrel shaft A guide guide for moving 12 to the winding roll 20 may be used. In this case, if guide guides are provided at both ends of the mandrel shaft 12, the paste A can be applied over the entire length and the entire circumference of the outer surface of the long paper tube 10. Therefore, it is possible to produce a toilet paper roll group having no uncoated portion in all.
ここで、非塗布部Ｚの長さ範囲を、紙管１の長さＬの４０〜６５％としたのは、助走円盤３０の厚みとして４０％以上が必要であること、上限を６５％としても、巻不良の発生率低減及び断紙防止効果に有意差がないことを知見しているからである。 Here, the reason why the length range of the non-applied portion Z is 40 to 65% of the length L of the paper tube 1 is that 40% or more is required as the thickness of the run-up disk 30, and the upper limit is 65%. This is because it has been found that there is no significant difference in the reduction rate of winding defects and the effect of preventing sheet breakage.
ちなみに、月産約２５００トンの設備において、従来の図２の形態における巻不良の発生率を１００％とした場合、本発明の形態とすることで、約２３％に低減し、かつ、断紙はまったく生じないようになった。 By the way, in the facility of about 2500 tons per month, when the occurrence rate of winding failure in the conventional form of FIG. 2 is assumed to be 100%, by adopting the form of the present invention, it is reduced to about 23% and the paper is cut off. No longer occurs.
