Definitions
- the present invention relates to a toilet roll product obtained by packaging a toilet roll wound with toilet paper having a crepe coated with a chemical solution, and a method for producing the toilet roll product.
- Toilet paper is generally in the form of a toilet roll in which a continuous strip is wound around a tube core called a paper tube. ing.
- toilet paper is used not only after defecation but also for wiping after urination, especially in women. Since wiping after urination in this woman involves contact with sensitive genital areas, it is moisturizing and soft. There is a potential demand for toilet paper.
- the conventional normal toilet roll is manufactured by transferring the roll roll manufactured by the paper making equipment to the winder, and rolling it to the diameter of the toilet roll with this winder to produce logs that are more than double the width of the toilet roll. Then, the log taken thereafter is cut into the width of the toilet roll to form a toilet roll.
- a continuous sheet unwound from a plurality of original rolls is laminated before being rewound in a winder.
- embossing is applied by a steel rubber method when a log is manufactured from an original roll set in a winder, and a chemical solution is applied to the embossed convex portion of the convex emboss roll to provide an original roll.
- This is a technique for transferring and applying a chemical solution to a continuous sheet unwound from a sheet.
- Patent Document 1 since the technique of Patent Document 1 applies the chemical liquid only to the apex of the embossed convex portion and applies the chemical liquid to the continuous sheet, the amount of the chemical liquid used is small, and a portion where no chemical liquid is applied is generated on the concave surface of the emboss. There is a risk that the surface smoothness and moisture retention will not be sufficient. Furthermore, since the time of applying the chemical solution with the weakest paper strength and the time of applying the emboss sandwiched between the continuous sheets at a predetermined pressure are likely to occur, paper breakage is likely to occur, and it is necessary to process at a low speed, making it difficult to increase productivity.
- Patent Document 2 is a technique of applying a chemical solution by a spray method after embossing when manufacturing a log from a raw roll set in a winder.
- Patent Document 2 since the technique of Patent Document 2 also uses a log immediately after application of a chemical solution, the chemical solution diffuses into the paper after the log is produced, and there is a drawback that the log is easily unrolled due to the elongation of the paper due to the elongation of the crepe. In particular, since the log is cut later to become a toilet roll, if a roll misalignment or mold breakage occurs in the log, it becomes a defective toilet roll and the yield is also deteriorated, which causes the production efficiency to be extremely reduced.
- Patent Document 3 is a technology for obtaining embossed crepe paper as a base paper for toilet paper products. After a continuous sheet is unwound from a plurality of raw rolls and superposed, a chemical solution is applied to the laminated continuous sheet. Further, embossing is applied after water is applied by spraying to form wet paper. And it is the technique of separating each continuous sheet laminated
- an oily chemical solution is known as a chemical solution with a small decrease in paper strength when the chemical solution is applied, and a toilet roll using such an oily chemical solution is also known, but such a toilet roll has sufficient improvement in surface smoothness. This is because the moisturizing property is insufficient, and among the chemical solutions, oily chemical solutions that do not easily penetrate into the paper layer are used. Moreover, there is a difficulty in terms of water decomposability necessary for this toilet roll.
- the main problems of the present invention are to maintain sufficient water disintegration performance necessary for toilet paper, while maintaining moisture (moisturity), flexibility (softness), and surface smoothness (smoothness). ) Is sufficiently improved, and a method for producing a toilet roll product that can be produced with high productivity is provided.

- wet paper strength enhancer is not added or a small amount is added even if the toilet paper requires water degradability. However, when added, it acts advantageously during log production in the latter winder. Therefore, considering this point, a small amount, specifically, 5 kg / t or less in weight ratio to the pulp slurry may be used. it can.
- the paper material used as the raw material of the primary raw material roll (primary raw material sheet) will be described.
- the paper material is obtained by adding an appropriate chemical to a slurry (pulp slurry) containing pulp as a main raw material as a fiber raw material. .
- the raw material pulp is not particularly limited, and an appropriate raw material pulp used for toilet paper can be selected and used. *
- the raw material pulp is a blend of NBKP and LBKP.
- waste paper pulp may be blended, but it is compatible with the lotion chemical solution according to the present invention, log production in a winder can be suitably performed, and the texture of the resulting tissue paper is desirable, so virgin pulp It is preferable to be composed only of NBKP and LBKP.
- chemicals added to the paper stock include the above-mentioned dry paper strength enhancer, wet paper strength enhancer, release agent, adhesive, pH adjuster such as caustic soda, sticky agent, antifoaming agent, preservative, slime control agent In addition, these chemicals may be applied to the wet paper in an appropriate process.

次いで、本発明の第2の実施形態を図9、図10を特に参照しながら説明する。なお、本形態はプライマシンX2において積層連続シートS2、S3に所謂シングルエンボスを付与する以外の他の構成については上記第1の実施形態と同様であり、上記説明の通りである。
次いで、本発明の第3の実施形態を図11を特に参照しながら説明する。なお、本形態はプライマシンX2において積層連続シートに所謂ダブルエンボスを付与する構成及びかかる構成を採ること関係する構成以外の他の構成については、上記第1の実施形態と同様であり、上記説明の通りである。また、各エンボス付与手段60及びエンボスの構成、エンボス付与条件等は、上記第2の実施形態と同様であり、上記説明の通りである。
図11に示す第3の実施形態にかかるプライマシンX2は、一次連続シートS1,S12を積層連続シートとする重ね合わせ部51、重ね合わせ部51で積層連続シートS2に対して薬液を付与する薬液付与手段53、薬液が付与された積層連続シートS3を薬液が付与された各連続シートS13、S14に分離するプライ離れ手段57、プライ離れ手段57によって分けられた各連続シートS13、S14に対して各々エンボスを付与するエンボス付与手段60,60、エンボス付与手段60,60でエンボスが付与された各連続シートS13,S14を再積層する再重ね合わせ部58(積層手段)がこの順に設けられており、薬液付与、各連続シートへのエンボス付与、実質的な積層がこの順で行なわれる。
次いで、本発明の第4の実施形態を図13を特に参照しながら説明する。なお、本形態はワインダーX3にて所謂シングルエンボスを付与する形態である。かかるワインダーX3にてシングルエンボスを付与する構成及びかかる構成を採ることに関係する構成以外の他の構成については上記第1の実施形態と同様であり、上記説明の通りである。また、各エンボス付与手段及びエンボスの構成、エンボス付与条件等は、上記第2の実施形態と同様であり、上記説明の通りである。
次いで、本発明の第5の実施形態を図14を特に参照しながら説明する。なお、本形態はワインダーX3にて所謂ダブルエンボスを付与する形態である。かかるワインダーにてダブルエンボスを付与する構成及びかかる構成を採ることに関係する構成以外の他の構成については上記第1の実施形態と同様であり、上記説明の通りである。また、各エンボス付与手段及びエンボスの構成、エンボス付与条件等は、上記第2の実施形態と同様であり、上記説明の通りである。
次いで、本発明の第6の実施形態を図30、図31を特に参照しながら説明する。本形態はプライマシンX2において積層手段を機能させずに単層の連続シートを巻取った二次原反ロールを製造し、ワインダーX3にかかる単層の原反ロールを巻取った複数の二次原反ロールをセットして、かかるワインダーにて各二次原反ロールから巻きだした二次連続シートの積層を行なう形態である。プライマシンX2において積層手段を機能させないようにするには、一つの一次原反ロールから連続シートを巻き出すようにすればよい。積層しない点以外の構成については第1の実施の形態と同様であり、上記説明の通りである。
第1の実施形態から第6の実施形態に共通するプライマシンX2における薬液付与手段(薬液付与工程)53の具体例について以下詳述する。
薬液付与手段53としてフレキソ印刷機を用いた例を図15~21に示す。フレキソ印刷は樹脂性の弾力性がある刷版を用いるため積層連続シートS2或いは各連続シートS13,S14(以下、単位積層連続シートS2等という)の表面にクレープの多少の凹凸があっても印圧で調整可でありムラのない塗工が可能であり、特に500m/分以上、更に700m/分の高速塗工を行なっても薬液付与後の積層連続シート等S3にシワが入り難くなる。また、一つのロールで幅広い薬液の粘度に対応でき、管理、設備メンテナンスの点で利点があり、生産性向上の点でも優れる。
フキレソ印刷におけるドクターチャンバー形式を本発明に適用した形態例を、特に図15~図20を参照しながら説明する。
次いで、フキレソ印刷における2ロール転写形式を適用した形態例を図21を参照しながら説明する。本形態例でも、積層連続シートS2等の表裏面に薬液Lを塗工すべく二つのフレキソ印刷機91C,91Dを用いている。各印刷機91C,91Dにおいては、薬液Lの入っている薬液タンク98C,98Dに回転可能な絞りロールでもあるディップロール92C,92Dが浸され、このディップロール92C,92Dが薬液タンク98C,98D外で回転可能なアニロックスロール93C,93Dに接しており、適当に薬液量が調整され量の薬液をアニロックスロール93C,93Dに受け渡す。薬液Lをアニロックスロール93C,93Dに受け渡すに、ディップロール92C,92Dを介することから2ロール転写方式と称される。ここで、ディップロール92C,92Dは薬液タンク98C,98Dから薬液Lを取り上げるとともに過剰な薬液をそのままアニロックスロール93C,93Dに受け渡さないようにする調整する役割を果たす。
次いで、フキレソ印刷における1ロール転写形式を本発明に適用した場合の形態例を説明する。この例は、前述の2ロール転写形式からディップロールを省略したものである(図面は省略する)。この場合、アニロックスロールが、それぞれ薬液タンクに浸されつつ回転可能に設置される。また、これらのアニロックスロールに対しては、アニロックスロール表面の薬液を掻き取るドクターブレードを設置する。このようなフレキソ1ロール転写形式は、メンテナンスが比較的容易であるという利点や、ブレードの摩耗や薬液中の紙粉等の異物の混入状態を容易に目視できるという利点を有している。
薬液付与工程(薬液付与手段)53としてスプレー塗工装置110,110を用いた例を図22~26を参照しながら説明する。本形態例では、図22に示すように、積層連続シートS2等の表裏面に薬液が塗工されるようにスプレー塗工装置110,110を設けることができる。このようにするには、図10に示されるように側方から積層連続シートS2等の表裏面に噴霧可能にペーパーランを設計する形態、積層連続シートS2等の表裏面に上下から噴霧する形態、上方から表裏面に噴霧するようにペーパーランを設計する形態が例示できる。もちろん、積層連続シートS2等の積層を一度剥離させて、各連続シートにスプレーした後、再度積層する形態等を採ることができる。
薬液塗付与工程(薬液付与手段)53としてインクジェット印刷機130を用いた例を図27~28を参照しながら説明する。
薬液付与工程(薬液付与手段)53としてカーテンコーター150を用いた例を説明する。カーテンコーター150としては、例えば、図29に示される従来既知のカーテンコーターが使用できる。なお、カーテンコーターは、薬液の膜を垂下させることから、二次連続シート等S2の表裏面に塗工する場合には二次連続シートS2等の表裏面が上方に位置するようにペーパーランを設計して各面に塗工する。
