実開平６−８６６８７号公報Japanese Utility Model Publication No. 6-86687 特開２００５−８７７８８号公報JP-A-2005-87788

従来、長尺芯管の外周面に幅広原紙の始端部を接着固定するための接着剤としては、通常、水溶性の接着剤が用いられていた。しかしながら、一般的な水溶性の接着剤は乾き難く、長尺芯管の外周に幅広原紙を巻き取った後でもべたつきが残る場合がある。このため、べたついた状態の接着剤が、幅広原紙の始端部だけでなく、この始端部の直上に重なる部分（複数枚分）にまで染み込んでしまうことがあった。このように、接着剤が幅広原紙の始端部以外の部分にまで染み込んだ場合には、最後の一巻きまでロール状衛生用紙を使い切ることが困難となり、無駄が生ずるという問題があった。特に、気温が低い冬場は接着剤が更に乾き難くなるため、上記の問題がより顕在化する傾向にあった。   Conventionally, a water-soluble adhesive is usually used as an adhesive for bonding and fixing the starting end of a wide base paper to the outer peripheral surface of a long core tube. However, a general water-soluble adhesive is difficult to dry, and stickiness may remain even after the wide base paper is wound around the outer periphery of the long core tube. For this reason, the adhesive in a sticky state may permeate not only to the starting end portion of the wide base paper, but also to a portion (for a plurality of sheets) that directly overlaps the starting end portion. As described above, when the adhesive soaks into a portion other than the starting end of the wide base paper, it is difficult to use up the roll-like sanitary paper until the last roll, resulting in a waste. In particular, in winter when the temperature is low, the adhesive is more difficult to dry, and thus the above-mentioned problem tends to become more apparent.

このような問題を解消するため、例えば、製造設備の付近や製造設備が配置された施設内に加温装置を設置し、接着剤の乾燥を促進する等の対策を講ずる必要があった。しかしながら、このような加温装置は、高価であるとともにランニングコストも嵩むものであった。このため、より簡便に製造する方法を開発する必要性があった。   In order to solve such a problem, for example, it is necessary to take measures such as installing a heating device in the vicinity of the manufacturing equipment or in a facility where the manufacturing equipment is arranged to promote drying of the adhesive. However, such a heating apparatus is expensive and increases the running cost. For this reason, there has been a need to develop a method for manufacturing more easily.

本発明は、このような従来技術の有する問題点に鑑みてなされたものであり、その課題とするところは、高価な設備を用いなくとも、無駄なく最後まで使い切ることが可能なロール状衛生用紙を簡便に製造することが可能なロール状衛生用紙の製造方法を提供することにある。   The present invention has been made in view of the above-described problems of the prior art, and the problem is that a roll-like sanitary paper that can be used up to the end without waste without using expensive equipment. It is in providing the manufacturing method of the roll-form sanitary paper which can be manufactured easily.

本発明者らは上記課題を達成すべく鋭意検討した結果、幅広原紙の始端部の接着固定に再湿糊を用いることによって、上記課題を達成することが可能であることを見出し、本発明を完成するに至った。   As a result of intensive studies to achieve the above-mentioned problems, the present inventors have found that the above-mentioned problems can be achieved by using a re-wetting paste for bonding and fixing the starting end of a wide base paper. It came to be completed.

即ち、本発明によれば、以下に示すロール状衛生用紙の製造方法が提供される。   That is, according to this invention, the manufacturing method of the roll-shaped sanitary paper shown below is provided.

It should be understood that modifications, improvements, and the like appropriately added to the embodiments described above fall within the scope of the present invention.

［１］ロール状衛生用紙の製造方法：
図１は、本発明のロール状衛生用紙の製造方法における、接着層を形成する工程及び幅広のログを得る工程の一例を示す模式図である。本発明のロール状衛生用紙の製造方法は、図１に示すような、その外周面に再湿糊層１２を有する長尺芯管１０を用意し、この再湿糊層１２を水で濡らして再湿糊層１２に接着性を付与し、接着層１３を形成する工程（接着層形成工程）を備えている。また、本発明のロール状衛生用紙の製造方法は、図１に示すような、形成された接着層１３に幅広原紙２４の始端部を接着固定するとともに、幅広原紙２４を製品長さ分だけ長尺芯管１０に巻き取って幅広のログ２６を得る工程（巻き取り工程）を備えている。本発明のロール状衛生用紙の製造方法は、得られた幅広のログを製品幅に切断し、複数のロール状衛生用紙を得る工程（切断工程）を更に備えている。 [1] Manufacturing method of rolled sanitary paper:
FIG. 1 is a schematic diagram showing an example of a process for forming an adhesive layer and a process for obtaining a wide log in the method for producing a roll-like sanitary paper of the present invention. The roll sanitary paper manufacturing method of the present invention is prepared by preparing a long core tube 10 having a rewet paste layer 12 on its outer peripheral surface as shown in FIG. 1, and wetting the rewet paste layer 12 with water. A process (adhesive layer forming process) in which adhesiveness is imparted to the rewet paste layer 12 and an adhesive layer 13 is formed is provided. Further, the roll sanitary paper manufacturing method of the present invention is such that the starting end portion of the wide base paper 24 is bonded and fixed to the formed adhesive layer 13 as shown in FIG. 1, and the wide base paper 24 is lengthened by the product length. A step (winding step) for obtaining a wide log 26 by winding it around the long core tube 10 is provided. The method for producing roll-like sanitary paper of the present invention further includes a step (cutting step) of obtaining a plurality of roll-like sanitary paper by cutting the obtained wide log into a product width.

本発明のロール状衛生用紙の製造方法では、ロール状トイレットペーパーやロール状キッチンタオル等のロール状衛生用紙の巻き芯（コア）となる長尺芯管として、その外周面の少なくとも一部に再湿糊層を有するものを用いることを特徴の一つとしている。この再湿糊層は、切手、壁紙、及び襖紙等の紙類を接着するために用いられる、いわゆる「再湿糊」を層状（膜状）に塗布及び乾燥することによって形成されている。   In the method for producing rolled sanitary paper of the present invention, a long core tube serving as a winding core (core) of rolled sanitary paper such as rolled toilet paper or rolled kitchen towel is re-applied on at least a part of the outer peripheral surface thereof. One of the features is that a material having a wet paste layer is used. This re-wet paste layer is formed by applying and drying a so-called “re-wet paste” used for bonding paper such as stamps, wallpaper, and paper, in a layered form (film form).

再湿糊は、乾燥速度が迅速であるとともに、塗布及び乾燥した状態ではべたつかないが、乾燥した表面を水で濡らすと接着性が発現するといった特性を有する糊（接着剤）である。また、主として紙類の接着に用いられていることから明らかなように、紙類に対しては浸透し難い特性をも有するものである。このため、この再湿糊を、幅広原紙の始端部を長尺芯管の外周に接着固定するためのピックアップ糊として使用することにより、始端部の直上に重なる部分にまでピックアップ糊が染み込むといった不具合が生じ難く、最後の一巻きまで無駄なく使用可能なロール状衛生用紙を簡便に製造することができる。   The re-wet paste is a paste (adhesive) that has a rapid drying speed and is not sticky in the applied and dried state, but has a property that adhesiveness is exhibited when the dried surface is wetted with water. Further, as is apparent from the fact that it is mainly used for adhesion of paper, it also has a property that it is difficult to penetrate into paper. For this reason, the use of this re-wetting paste as a pick-up paste for bonding and fixing the starting end of a wide base paper to the outer periphery of the long core tube causes the pick-up paste to soak into the portion directly above the starting end. Therefore, it is possible to easily produce a roll-like sanitary paper that can be used without waste until the last roll.

［１−１］長尺芯管：
本発明のロール状衛生用紙の製造方法では、その外周面に再湿糊層を有する長尺芯管を使用する。この「長尺芯管」は、ロール状衛生用紙の巻き芯となる部材であり、通常、ボール紙等の厚紙からなる紙管が用いられる。ロール状衛生用紙の種類により異なるが、外径３５〜５０ｍｍφ、厚さ０．５〜１．５ｍｍの紙管が好適に用いられる。この長尺芯管は、一時に複数個のロール状衛生用紙を製造できるようロール状衛生用紙の幅の１０〜３０倍の長さを有するものである。 [1-1] Long core tube:
In the method for producing roll-like sanitary paper of the present invention, a long core tube having a rewet adhesive layer on its outer peripheral surface is used. The “long core tube” is a member that serves as a core for rolled sanitary paper, and a paper tube made of cardboard such as cardboard is usually used. Although different depending on the type of roll-like sanitary paper, a paper tube having an outer diameter of 35 to 50 mmφ and a thickness of 0.5 to 1.5 mm is preferably used. This long core tube has a length 10 to 30 times the width of the roll-like sanitary paper so that a plurality of roll-like sanitary papers can be produced at a time.

図２は、長尺芯管の製造工程の一例を示す模式図である。図２に示すように、外層用ロール２ａ及び内層用ロール３ａから、外層用原紙２ｂ及び内層用原紙３ｂがそれぞれ送出される。外層用原紙２ｂの裏面には、接着剤塗布部６によって接着剤４が塗布される。接着剤４としては、一般的な水溶性接着剤等を使用することができる。また、外層用原紙２ｂの表面には、転写ローラー８によって再湿糊が塗布される。なお、図２に示すような転写ローラー８ではなく、例えば、スポンジ状の塗布部材を使用して外層用原紙２ｂの表面に再湿糊を塗布してもよい。   FIG. 2 is a schematic diagram showing an example of a manufacturing process of a long core tube. As shown in FIG. 2, the outer layer base paper 2b and the inner layer base paper 3b are sent out from the outer layer roll 2a and the inner layer roll 3a, respectively. The adhesive 4 is applied to the back surface of the outer layer base paper 2 b by the adhesive application unit 6. As the adhesive 4, a general water-soluble adhesive or the like can be used. Further, a re-wetting paste is applied to the surface of the outer layer base paper 2 b by the transfer roller 8. Instead of the transfer roller 8 as shown in FIG. 2, for example, a re-wetting paste may be applied to the surface of the outer layer base paper 2b using a sponge-like application member.

外層用原紙２ｂの表面に塗布される再湿糊としては、切手等の紙類の接着に使用される一般的な再湿糊を用いることができる。なお、具体的な再湿糊としては、例えば特開２００１−３２３２３４号公報等において開示されたものを挙げることができるが、本発明のロール状衛生用紙の製造方法において用いることのできる再湿糊は、前記公報において開示されたもの等に限定されることはない。   As the re-wetting paste applied to the surface of the outer layer base paper 2b, a general re-wetting paste used for bonding paper such as stamps can be used. Specific examples of the re-wet paste include those disclosed in JP-A-2001-323234 and the like, and the re-wet paste that can be used in the method for manufacturing roll-like sanitary paper of the present invention. Are not limited to those disclosed in the publication.

裏面に接着剤４及び表面に再湿糊がそれぞれ塗布された外層用原紙２ｂと、内層用原紙３ｂとが、一定の速度で回転する芯棒５へと供給されると、内層用原紙３ｂ上に外層用原紙２ｂが重なるようにスパイラル状に貼り合わされ、連続した長い紙管である長尺捲回体９が形成される。この長尺捲回体９をカッター７により所定の長さに切断することによって、図３に示すような、内層３と外層２を備え、その外周面上（外層２の表面上）に再湿糊からなる再湿糊層１２が形成された長尺芯管１０を得ることができる。   When the outer layer base paper 2b and the inner layer base paper 3b each coated with the adhesive 4 on the back surface and the re-wetting paste on the front surface and the inner layer base paper 3b are supplied to the core rod 5 rotating at a constant speed, the inner layer base paper 3b The outer layer base paper 2b is laminated in a spiral shape so as to overlap with each other, and a long wound body 9 which is a continuous long paper tube is formed. The long wound body 9 is cut into a predetermined length by a cutter 7 to provide an inner layer 3 and an outer layer 2 as shown in FIG. 3, and re-wet on the outer peripheral surface (on the surface of the outer layer 2). The long core tube 10 in which the rewet paste layer 12 made of glue is formed can be obtained.

長尺芯管１０の外周面上に形成された再湿糊層１２は、塗布された再湿糊が乾燥することで形成されている。再湿糊層１２はこの状態のままでは接着性を発揮しておらず、べたついていないために、長尺芯管１０の取り扱いは容易である。なお、再湿糊層は、長尺芯管の外周面の全ての領域において形成されていなくてもよく、長尺芯管の外周面の少なくとも一部に形成されていればよい。   The rewet paste layer 12 formed on the outer peripheral surface of the long core tube 10 is formed by drying the applied rewet paste. Since the re-wet paste layer 12 does not exhibit adhesiveness in this state and is not sticky, the long core tube 10 is easy to handle. Note that the rewet adhesive layer does not have to be formed in the entire region of the outer peripheral surface of the long core tube, and only needs to be formed on at least a part of the outer peripheral surface of the long core tube.

［１−２］接着層形成工程：
本発明のロール状衛生用紙の製造方法においては、例えば、図１に示すような構成のワインダー３４を使用する。先ず、長尺芯管１０に円筒状又は円柱（棒）状のマンドレルシャフト１４を挿入し、長尺芯管１０をマンドレルシャフト１４に固定する（図１中のＡ部）。長尺芯管１０が固定されたマンドレルシャフト１４は、幅広原紙２４が送出されるローラー３２の方へ移動する。そして、マンドレルシャフト１４は、噛み合わせのギア（図示せず）等の作用によって長尺芯管１０の周方向に回転を開始するとともに、適度な量の水がスプレー１６によって再湿糊層１２に対して噴霧される（図１中のＢ部）。水が噴霧されることで濡らされた再湿糊層１２には接着性が再び発現し、接着性を有する接着層１３が形成されることとなる（図１中のＣ部）。 [1-2] Adhesive layer forming step:
In the method for manufacturing roll-like sanitary paper of the present invention, for example, a winder 34 having a configuration as shown in FIG. 1 is used. First, a cylindrical or columnar (rod) mandrel shaft 14 is inserted into the long core tube 10 to fix the long core tube 10 to the mandrel shaft 14 (A portion in FIG. 1). The mandrel shaft 14 to which the long core tube 10 is fixed moves toward the roller 32 to which the wide base paper 24 is fed. The mandrel shaft 14 starts to rotate in the circumferential direction of the long core tube 10 by the action of a meshing gear (not shown) and the like, and an appropriate amount of water is applied to the rehumidified glue layer 12 by the spray 16. On the other hand, it is sprayed (B section in FIG. 1). The re-wet paste layer 12 that has been wetted by spraying water again exhibits adhesiveness, and an adhesive layer 13 having adhesiveness is formed (part C in FIG. 1).

スプレー１６で噴霧する水の量、或いはマンドレルシャフト１４の回転速度等を適度に制御することによって、再湿糊層１２の濡れ具合や、形成される接着層１３のべたつきの程度を制御することができる。また、再湿糊の乾燥速度は、一般的な水溶性接着剤に比して迅速であることから、接着層１３を乾燥させるために加温装置等を使用する必要がなく、簡便かつ低コストにロール状衛生用紙を製造することができる。   By appropriately controlling the amount of water sprayed by the spray 16 or the rotation speed of the mandrel shaft 14, it is possible to control the wetness of the rewet adhesive layer 12 and the degree of stickiness of the formed adhesive layer 13. it can. Further, since the drying speed of the re-wet paste is quicker than that of a general water-soluble adhesive, it is not necessary to use a heating device or the like to dry the adhesive layer 13, and it is simple and low-cost. A roll-like sanitary paper can be manufactured.

再湿糊層１２を水で濡らすには、図１に示すようなスプレー１６を使用することの他、例えば転写ローラー等を使用することも好ましい。なお、スプレー１６で水を噴霧する場合、水が飛散して他の箇所（例えば、幅広原紙２４等）に付着することを防止すべく、ローラー３２とスプレー１６の間、或いはローラー３２から送出されてくる幅広原紙２４とスプレー１６の間に遮蔽版１８を設置することが好ましい。   In order to wet the re-wet paste layer 12 with water, it is also preferable to use a transfer roller, for example, in addition to using the spray 16 as shown in FIG. In addition, when spraying water with the spray 16, it is sent between the roller 32 and the spray 16 or from the roller 32 in order to prevent water from splashing and adhering to other parts (for example, the wide base paper 24). It is preferable to install a shielding plate 18 between the incoming wide base paper 24 and the spray 16.

［１−３］巻き取り工程：
本発明のロール状衛生用紙の製造方法においては、図１に示すように、接着層１３に幅広原紙２４の始端部を接着固定するとともに、マンドレルシャフト１４を回転させ、幅広原紙２４を製品長さ分だけ長尺芯管１０の外周に巻き取る（図１中のＣ部及びＤ部）。接着層１３を構成する再湿糊は、幅広原紙２４の概ね始端部のみを接着固定し、幅広原紙２４に対して過度に浸透することがない。このため、再湿糊は、幅広原紙２４の始端部の直上に重なる部分までほとんど浸透せず、幅広原紙２４を複数巻きに渡って長尺芯管１０の外周上に接着固定してしまう等の不具合が生じ難い。 [1-3] Winding process:
In the method for producing roll-like sanitary paper of the present invention, as shown in FIG. 1, the starting end portion of the wide base paper 24 is bonded and fixed to the adhesive layer 13 and the mandrel shaft 14 is rotated to make the wide base paper 24 the product length. It winds up to the outer periphery of the long core tube 10 by the part (C part and D part in FIG. 1). The rewet glue constituting the adhesive layer 13 adheres and fixes only the starting end portion of the wide base paper 24 and does not permeate the wide base paper 24 excessively. For this reason, the re-wetting paste hardly penetrates to the portion directly over the starting end portion of the wide base paper 24, and the wide base paper 24 is bonded and fixed on the outer periphery of the long core tube 10 over a plurality of turns. It is difficult for problems to occur.

「幅広原紙」は、ロール状衛生用紙の中間体となる原紙であり、通常、ロール状衛生用紙の幅の１０〜３０倍の幅を有するものである。この幅広原紙には、１枚の原紙のみからなる１プライの他、２枚の原紙を重ね合わせた２プライ等、複数枚の原紙を重ね合わせたマルチプライのものも含まれる。なお、幅広原紙には、適当な間隔を隔てて切り取り用のミシン目を形成してもよく、肌触り等を改善すべくエンボス加工を施してもよい。   The “wide base paper” is a base paper that is an intermediate of the roll-like sanitary paper, and usually has a width that is 10 to 30 times the width of the roll-like sanitary paper. The wide base paper includes a multi-ply one in which a plurality of base papers are superposed, such as a single ply consisting of only one base paper, and a two ply in which two base papers are superposed. Note that perforations for cutting may be formed on the wide base paper at appropriate intervals, and embossing may be performed to improve the touch and the like.

幅広原紙２４の巻取り長さは、製造しようとするロール状衛生用紙の種類によって異なる。例えば、ロール状トイレットペーパーの場合であれば２５〜９０ｍ、ロール状キッチンタオルの場合であれば１０〜２０ｍとすることが一般的である。   The winding length of the wide base paper 24 differs depending on the type of roll-like sanitary paper to be manufactured. For example, in the case of rolled toilet paper, it is generally 25 to 90 m, and in the case of rolled kitchen towel, it is generally set to 10 to 20 m.

巻き取り終了に際しては、例えば図１に示すように、テールシール部２０において幅広原紙２４の終端部又は形成されたロールの外周面に接着剤を塗工し、ロールの外周面に幅広原紙２４の終端部を接着固定することが好ましい（図１中のＥ部）。接着剤としては、水溶性接着剤、又は始端部の接着固定する場合と同じく再湿糊が好ましい。以上の操作により、幅広のロール状衛生用紙であるログ２６を得ることができる（図１中のＦ部）。   At the end of winding, for example, as shown in FIG. 1, an adhesive is applied to the end portion of the wide base paper 24 or the outer peripheral surface of the formed roll in the tail seal portion 20, and the wide base paper 24 is applied to the outer peripheral surface of the roll. It is preferable to bond and fix the end portion (E portion in FIG. 1). As the adhesive, a water-soluble adhesive or a re-wet paste is preferable as in the case where the starting end portion is bonded and fixed. The log 26 which is a wide roll sanitary paper can be obtained by the above operation (F section in FIG. 1).

［１−４］切断工程：
本発明のロール状衛生用紙の製造方法においては、マンドレルシャフト１４から抜き出した幅広のログ２６（図１のＦ部参照）を製品幅に切断する。ログの切断は、ログソー（丸刃）、バンドソー（平刃）等、従来公知の切断刃を使用して行うことができる。刃の厚さとしては、２〜１０ｍｍのものが好適に用いられる。製品幅はロール状衛生用紙の種類によって異なる。例えば、ロール状トイレットペーパーの場合であれば１０５〜１１４ｍｍ、ロール状キッチンタオルの場合であれば２１０〜２２８ｍｍとすることが一般的である。 [1-4] Cutting step:
In the method for producing roll-like sanitary paper of the present invention, a wide log 26 (see F part in FIG. 1) extracted from the mandrel shaft 14 is cut into the product width. The log can be cut using a conventionally known cutting blade such as a log saw (round blade) or a band saw (flat blade). A blade having a thickness of 2 to 10 mm is preferably used. The product width varies depending on the type of roll sanitary paper. For example, in the case of rolled toilet paper, it is generally 105 to 114 mm, and in the case of rolled kitchen towel, it is generally 210 to 228 mm.
