PROBLEM TO BE SOLVED: To provide toilet paper imparted with deodorant including organic acid.SOLUTION: The toilet roll, which has toilet paper imparted with deodorant and wound around a paper tube, has plural layers of toilet paper base sheets, and at least a face of the layered inner surfaces is imparted with deodorant having organic acid as a main component, the deodorant imparting area is in the range of 5% or more in a plane view and the deodorant content as an active ingredient is 0.0001-2.0 g/min the whole of the toilet paper to make a solution.

Description

  The present invention relates to a toilet roll in which strip-shaped toilet paper is wound around a paper tube.

  Conventionally, it has been proposed to apply a deodorant to a toilet roll for the purpose of deodorizing the toilet space. For example, a method of adding a deodorant to a tail seal paste that adheres the end of the roll of toilet paper, a method of applying a deodorant to the inner surface of a paper tube, and the like have been proposed. However, the former has a problem in the sustainability of the deodorizing effect because the deodorant imparting portion is used at the same time as the start of use. In the latter case, since the position where the deodorant is applied is a limited part called a paper tube, the opportunity for contact between the odor component and the deodorant is not sufficient, and further improvement of the deodorant function is required. .

  Then, it is possible to give a deodorant to the toilet paper which comprises a toilet roll. If a deodorant can be given to toilet paper, the contact opportunity with an odor component will improve markedly. In the case where a deodorant is applied to the toilet paper itself, this can be easily achieved by applying a deodorant to both outer surfaces of the toilet paper.

  However, since toilet paper directly touches the skin when used, some consumers dislike that the deodorant touches the skin when used. For this reason, when providing a deodorant to toilet paper in a toilet roll, it is desirable to provide a deodorant in the position which a user does not touch at the time of use.

  In addition, some deodorizers have an excellent deodorizing effect against main malodorous components of toilet spaces such as ammonia such as organic acids, but such acids are iron in the toilet roll manufacturing equipment. Rust the material. Toilet roll manufacturing equipment is equipped with a smooth steel guide roll (also called a paper roll) to form a toilet paper transport path, but the organic acid affects the surface properties of the guide roll. give. And if the surface of a guide roll is roughened by a deodorant, it will become a factor of paper dust increase and operativity deterioration. This can be prevented to some extent by changing the guide roll to one made of stainless steel or chrome plating, or by increasing the frequency of cleaning, but in order to replace or clean many guide rolls and other members Expensive and troublesome. Furthermore, toilet rolls are often printed with a pattern to improve design, or soft and bulky, and embossed to improve design. In the manufacturing process of toilet rolls that impart embossing and embossing, the conveying path is more complicated and requires a large number of guide rolls, making it more difficult to manufacture a toilet roll having a more deodorant applied to the outer surface. As described above, it has been very difficult to produce a toilet roll by applying a deodorant containing an organic acid as an active ingredient to toilet paper to the extent that a sufficient deodorizing effect is exhibited.

  Embodiments of the present invention will be described below with reference to FIGS. However, the present invention is not limited to this embodiment.

[Toilet roll]
An embodiment of a toilet roll according to the present invention will be described with reference to FIGS. The toilet roll 10 according to the present embodiment is one in which a long toilet paper 12 is wound around a paper tube 11 and a deodorant is applied to the toilet paper 12 itself.

  As for the size of the toilet roll 10 according to the present embodiment, the width L1 is 100 to 115 mm, the diameter L2 is 100 to 120 mm, the winding length (full length of the toilet paper) is 18 to 70 m, and the paper tube inner diameter L3 is 35 to 50 mm. It is desirable that If it is this size, the paper holder for a general toilet roll can be utilized, the length of the toilet paper 12 is also sufficient, and there is no possibility that winding may collapse.

The toilet paper 12 according to the present embodiment desirably has a paper thickness of 100 to 350 μm and a US basis weight of 11.0 to 25.0 g / m ² per ply. If it is this range, the softness and water absorption at the time of use can be ensured. In addition, the tsubo in accordance with the present invention is based on the tsubo tsubo measurement method of JIS P 8124 (1998), and the paper thickness is the same after the humidity is sufficiently adjusted under the conditions of JIS P 8111 (1998). The average value measured five times using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho) under the conditions. The paper thickness is measured with a plurality of plies.

  The toilet paper 12 according to the present embodiment includes 90% or more of pulp fibers, preferably 98% or more, and more preferably 100%. As the pulp fiber, LBKP (hardwood kraft pulp) and NBKP (conifer kraft pulp) are most preferable, and are particularly composed of LBKP and NBKP, and the blending ratio of LBKP exceeds 50%, preferably 70% or more. Good.

  Here, the toilet paper 12 of the present embodiment has a ply structure in which a plurality of toilet paper base papers 13 are laminated characteristically as shown in FIGS. A deodorant that is an organic acid or a salt thereof is applied to at least one surface of 13D. (In the figure, the deodorant application position is indicated by reference numeral 15). Since the deodorant imparting portion 15 is positioned on the laminated inner surfaces 13A to 13D, it becomes difficult for the deodorant to touch the skin during use.

  The form shown in FIG. 2 is a two-ply laminated structure, and a deodorant is applied to both of the two laminated inner surfaces 13A and 13B, but it is not necessarily required to be applied to both surfaces 13A and 13B. For example, a deodorant may be given only to one lamination inner surface 13A.

  Moreover, the form shown in FIG. 3 is a three-ply laminated structure, and in the case of this three-ply structure, the laminated inner surface has four faces 13A to 13D. It is sufficient that an agent is applied (in the illustrated form, a deodorizing agent is applied to all the laminated inner surfaces 13A to 13D).

  In addition, about the number of plies in the toilet paper 12 of this embodiment, it is desirable to set it as 2-4 plies. If it exceeds 4 plies, the toilet paper is too thick and difficult to use, and it becomes difficult to secure a sufficient winding length.

  Moreover, in the toilet roll 10 of this embodiment, since the deodorizing agent is located on the laminated inner surface 13A of the toilet paper 12, the deodorizing effect of the toilet space by the deodorant permeates through the toilet paper base paper 13 and disappears. The effect of the odorant is demonstrated. That is, the deodorizing agent passes through the toilet paper base paper 13 and volatilizes, or the air around the toilet roll permeates through the toilet paper base paper 13 and comes into contact with the deodorant in the deodorant-applying portion 15, thereby providing a deodorizing effect. Demonstrated. For this reason, in the toilet roll 10 of the present invention, regardless of the number of plies, in the state in which the toilet paper 12 is wound around the paper tube 11, the laminated inner surface that is always close to the surface (winding outer surface) positioned on the outer surface side of the paper tube 11. In addition, it is desirable to have a deodorant-providing surface.

  Therefore, at least in the state of the toilet roll 10, it is desirable that a deodorant is applied to the inner surface of the laminate closest to the outer surface of the winding. If a deodorant is given to this surface, it is easy to improve the volatilization of the deodorant and the contact with the surrounding air, and the deodorizing effect can be particularly enhanced. The surface close to the winding outer surface will be described in more detail. Specifically, in the two-ply form shown in FIG. 2, if it is provided on one of the two laminated inner surfaces 13A and 13B, it is denoted by reference numeral 13A. In the three-ply form shown in FIG. 3, it is a surface indicated by reference numeral 13A. However, in this invention, it does not deny that the deodorizer is provided to all the laminated inner surfaces.

  A particularly preferred form of the present invention is a form in which a deodorant is applied to both laminated inner surfaces 13A and 13B of two two-ply surfaces as shown in FIG. 2, and a surface close to the four-sided winding outer surface of three plies. This is a form in which a deodorant is applied to the two surfaces 13A and 13B. Manufacture is easy, the application amount of the deodorant can be sufficient, and the contact between the deodorant and the outside air can be sufficiently secured even in a roll form. Further, the toilet paper 12 can be easily designed in terms of softness, and the winding length can be sufficiently secured.

  On the other hand, in the toilet paper 12 of the present embodiment, the deodorant application area is in a range of 5% or more in plan view. More preferably, it is 20% or more of range. The upper limit is 100%, which is the deodorant application range on the entire surface. Here, the range in which the application area is 5% in plan view means that the range of the portion to which the deodorant is applied when viewed from one side of the paper has a range of 5% or more of the one side. It is that. Therefore, when provided on only one surface of the laminated inner surface, the application range of the deodorant on the application surface is 5% or more. When a deodorant is applied to a plurality of laminated inner surfaces, the range in which the deodorant application range on each surface overlaps with the non-overlapping portion in the laminated state of each surface is 5% of one surface That is all.

  Here, in the present invention, a deodorant is applied only to the tip of the long toilet paper 12, a deodorant is applied only to the winding start portion, and only the central portion of the entire length of the toilet paper. In this case, the deodorizing effect may be reduced or not obtained at the initial stage of use or the latter stage of use. Therefore, preferably, even if there is a part to which the deodorant is not provided in a specific range in the longitudinal direction × width direction of the long toilet paper, the longitudinal length of the part is less than 1 m. Is desirable. In other words, in the present invention, it is desirable that a deodorant application portion is present at least every 1 m in the longitudinal direction of the toilet paper. If the said part is less than 1 m, deodorizing performance can fully be acquired. That is, since the toilet paper which comprises a toilet roll has a certain amount of air permeability even when wound in a roll shape, even if there is a deodorant-unapplied portion of about 1 m, the deodorizing effect can be sufficiently exerted. Most particularly preferably, the deodorizer is located over the entire length of the toilet paper 12 and more particularly preferably dispersed throughout the paper surface. Toilet rolls have a shorter roll circumference as they approach the center of the roll, but if deodorant is applied within the range of the circumference of the paper tube, it is always close to the outer surface of the roll from the start of use to the end of use. The deodorant imparting portion is located at the position, and the deodorizing effect can be continuously exhibited from the start of use to the end of use.

  Thus, in the toilet roll 10 which concerns on this embodiment, since the deodorizer is provided to the toilet paper 12, the deodorizer is located in the surrounding surface 12A which occupies the wide range of the toilet roll 10 Therefore, compared with the case where the deodorizer is applied only to a narrow range such as the paper tube 11, the chance of contact with the malodorous component in the toilet space is increased, and the deodorizing effect is excellent. However, the toilet roll 10 according to the present invention does not deny that the paper tube is provided with a deodorant.

  Further, in the case where the deodorant is disposed intermittently or continuously at appropriate intervals from the toilet paper tip to the end of the toilet paper, every time the toilet paper 12 is used, a new toilet is provided on the peripheral surface 12A of the toilet roll. Since the paper 12 is positioned, a new deodorant is positioned near the peripheral surface each time, and the deodorizing effect is excellent in durability.

On the other hand, the content of the deodorant as the whole toilet paper according to this embodiment is preferably 0.0002 to 2.0 g / m ² as an active ingredient. More preferably, it is 0.006-0.8 g / m < ² >. Most preferably, it is 0.01-0.5 g / m < ² >. 0.0002 g / m hardly deodorizing effect is obtained is less than ^2, although it exceeds 2.0 g / m ² deodorizing effect can be obtained, with the coating amount is excessive, especially the cost.

  Here, the deodorizer according to the present invention is an organic acid or a salt thereof. One or more of these may be included. Among them, it is desirable that the organic acid or a salt thereof is polyphenol or a derivative or analog of polyphenol extracted from plants such as tea bowls and grapes and processed products of plants. Although it has a high deodorizing function with respect to ammonia, which is one of the malodorous components, due to the reactivity due to the phenolic hydroxyl group, it is not preferable to apply to the outer surface of the toilet paper because it oxidizes iron. is there.

Polyphenol, polyphenol derivatives, and analogs exhibit a deodorizing effect by a chemical reaction with a malodorous component in the toilet space, and exhibit an extremely excellent deodorizing effect in the toilet space. Further, among polyphenol derivatives, in addition to ammonia, there are those reactive to hydrogen sulfide, methyl mercaptan, trimethylamine and having a deodorizing function. Of course, polyphenols used in the present invention are such It may be a thing.

  More preferred specific examples of the polyphenols and polyphenol derivatives and analogs according to the present invention are tannin, catechin, rutin, anthocyanin, ellagic acid, coumarin, flavone, and derivatives or precursors thereof. These exert a particularly high deodorizing effect on the odor component of the toilet. A plurality of these substances may be provided as appropriate.

Of the above specific examples, tannin and its derivatives are particularly preferable. Tannin and tannin derivatives are excellent in deodorizing function because they have a large molecular weight and many phenolic hydroxyl groups. Tannin may be either condensed tannin or hydrolyzed tannin. Further, among tannins, cocoon tannins derived from cocoons have a very large molecular weight and are extremely excellent in deodorizing effects. Therefore, the deodorant component according to the present invention contains at least one of cocoon tannins and cocoon tannin derivatives. It is better to do so. However, as the tannins and tannin derivatives increase in concentration, the characteristic brownish brown color becomes prominent, so if applied over 2.0 g / m ² , the toilet paper base will be dyed brownish, reducing the cleanliness. There is a risk of causing.

  On the other hand, in the toilet roll 10 according to the present invention, it is desirable that an emboss 14 is provided on the toilet paper 12 as shown in FIG. As shown in FIG. 4, the embossed protrusion 14A of one toilet paper base paper 13 faces the other toilet paper base paper, and the embossed convex part is provided between the other toilet paper base paper as shown in FIG. A so-called double embossed form having a gap, not shown, but only the embossed convex part is present on one surface of the toilet paper 12, and only the concave part corresponding to the embossed convex part is formed on the other surface. Any of so-called single embossed forms may be used. Since the emboss 14 is applied, the surface becomes bulky, and the area of the paper increases, so that the chance of contact between the deodorant and the outside air is further increased. In particular, among the toilet paper base paper 13 constituting the ply shown in FIG. 4, the embossed portion is laminated so that the embossed convex top portion 14A is located on the inner surface side of the laminate to form a gap. Double embossing is desirable. In this embossing mode, voids are formed between the plies by embossing, so that the air permeability is excellent, the deodorant and the outside air are more easily contacted, and a high deodorizing effect is obtained.

  In the case of the double embossing, it is desirable that the laminate paste 16 is disposed on the embossed convex top 14A as shown in the drawing, and the toilet paper base papers are bonded to each other. If it does in this way, ply peeling will be prevented suitably.

In the example of embossing in the present embodiment, the specific embossing pattern, embossing depth, embossing density, shape of individual unit embossing constituting embossing, and embossing area are not limited. . It can be determined as appropriate in consideration of the effectiveness of the deodorant, the properties of the deodorant solution, the amount of the deodorant, the design by embossing, the bulkiness, and the softness. If a preferable example is shown, the emboss density of 30-100 pieces / cm < ² > and the emboss depth of 0.2-2.0 mm were given to the whole paper surface, the form of what is called a micro emboss, 0.1-25 pieces / emboss density / It is an embossing form also called macro embossing or design embossing given to draw a pattern with cm ² and an embossing depth of 0.3 to 2.5 mm. Among them, embossing, which is also called macro embossing or design embossing, is particularly desirable because it has a wide top and can easily apply an appropriate amount of laminate paste, and can also improve the design.

  On the other hand, in the toilet paper of this embodiment, it is desirable that pattern printing is performed on the outer surface of the laminate. When pattern printing is given to the lamination | stacking outer surface, the designability of a toilet roll will improve.

[Manufacturing method of toilet roll]
Next, an example of a method for manufacturing the toilet roll of the present invention will be described with reference to FIGS. In order to manufacture the toilet roll of this embodiment, it can manufacture efficiently with this example of a manufacturing method, and it is especially effective, and can have the characteristic characteristic resulting from the example of a manufacturing method shown here. However, the method for producing the toilet roll of the present invention is not limited to this method.

  As shown in FIG. 5, the manufacturing method of the toilet roll of this embodiment includes a paper tube forming step (A) for manufacturing a long paper tube 30, and a log obtained by winding toilet paper around the long paper tube. Forming a toilet paper in the log forming step (B) for manufacturing the log, the log cutting step (C) for cutting the log into individual toilet rolls, and the log forming step illustrated in FIGS. 7 and 8 A secondary raw roll.

(Paper tube forming step (A))
In the paper tube forming process of the present embodiment, as shown in FIG. 5A and FIG. 6, one of the two strip-shaped paper tube base papers 31 and 32 fed out from the original rolls 31A and 32A. Adhesive glue 44 is applied to one side of the tube base paper 31 by a gluing roll 51, and the other paper tube base paper 32 is partially overlapped in the width direction on the surface of the one paper tube base paper 31, and the other paper tube The surface of the base paper 32 that does not contact the gluing surface is the surface facing the mandrel shaft 52, that is, the surface that becomes the inner surface of the paper tube, and the paper tube base papers 31 and 32 are spirally wound around the mandrel shaft 52 to continuously form a cylindrical portion. 3 and the cylindrical portion 3 is cut by a cutter 58 with a width more than a multiple of the toilet roll to form a long spiral paper tube 30 (also referred to as a spiral paper tube). This spiral paper tube has a two-layer laminated structure in which one paper tube base paper 31 is on the outer surface side of the paper tube and the other paper tube base paper 32 is on the inner surface side of the paper tube. In this embodiment, two paper tube base papers 31 and 32 are spirally wound. However, a long paper tube may be formed by spirally winding three or more paper tube base papers. Further, in the present invention, a flat paper tube can be used instead of the spiral paper tube.

  In the form shown in the drawing, each of the paper tube base papers 31 and 32 is wound around the mandrel shaft 52 by a flat belt 54 wound between a pair of pulleys 53 and 53 and a cylindrical portion located at a predetermined portion on the mandrel shaft 52. The paper tube base papers 31 and 32 are drawn at a predetermined angle with respect to the axis of the mandrel shaft 52 by the rotation, and are wound spirally. In the illustrated example, a pair of pulleys 53, 53 are arranged and rotational force is given to the cylindrical portion 3 by two flat belts 54, 54. However, a cylindrical shape is formed by a pair of pulleys and a flat belt. You may make it give rotational force to a part. Although not shown, the paper tube base papers 31 and 32 can be wound around the mandrel shaft 52 even if a roll is applied to the cylindrical portion 3 instead of the flat belt 54 to apply a rotational force.

  After the long paper tube 30 is formed in this way, the long paper tube 30 is supplied to the conveyor 55, and the winder in the next log forming step (B) is continuously or intermittently performed through an appropriate conveyance path. Supply to X2.

(Secondary film roll forming process)
As shown in FIGS. 7 and 8, the toilet roll manufacturing method of the present embodiment includes a base paper 61 having a width more than a multiple of the width of the toilet roll 10 fed out from the primary raw roll 60 made by a papermaking facility. After applying a deodorizing agent to the one surface by the coating device 65A, it is wound up by the winding device 66 to obtain a secondary raw roll 70 to which the deodorizing agent is applied.

  In the manufacturing method of the toilet roll of the present embodiment, in particular, after applying a deodorant to the base paper 61 fed out from the primary raw roll 60, the deodorizer application surface 61A is made of an iron roll such as a guide roll 6, 6,. It is preferable that the sheet is conveyed without contact with the sheet and wound around the secondary raw roll 70 so that the deodorant imparting surface becomes the wound inner surface. If it does in this way, there is no possibility that the grant side of a deodorizer containing organic acid may contact a guide roll etc., and make a guide roll etc. humus.

  Although a specific conveyance path is not particularly limited, for example, if a conveyance path is constructed as shown in FIGS. 7 and 8, a deodorant is applied to the base paper 61 fed out from the primary raw roll 60. After that, the deodorant imparting surface is conveyed without contacting the guide rolls 6, 6, and wound up so that the deodorant imparting surface 61 </ b> A becomes the winding inner surface. can do.

  On the other hand, in the manufacturing method of the toilet roll of the present embodiment, as the deodorant application device 65A for applying the deodorant to the base paper 61, a known roll transfer type coating machine, printing machine, spray application device, etc. Can be used. FIG. 7 shows an example of applying a deodorant using a roll transfer type deodorant application device, and FIG. 8 shows an example of applying a deodorant using a spray application device. The device for applying the deodorant is preferably a flexographic printing device, a gravure printing device, a two-fluid type spray coating device, or a rotor dampening spray type spray coating device. Particularly preferred is a flexographic printing apparatus. The flexographic printing apparatus is easy to adjust the printing pressure, and even if there is a crepe on the surface peculiar to the base paper of the toilet paper, it can be applied evenly, and it becomes difficult for wrinkles to enter the base paper. In addition, a single roll can handle a wide range of chemical viscosity, which is advantageous in terms of management and equipment maintenance.

  Further, in manufacturing the toilet roll 10 of the present embodiment, which is particularly provided with a pattern by printing, it is desirable to perform pattern printing on the base paper 61 when the deodorant is applied. In the form of FIG. 7, the multi-color printing device 65 in which a plurality of printing plate rolls 65B and 65a are arranged for one impression cylinder 65C is used to remove the deodorization by the printing plate roll 65a according to the deodorizing agent applying device 65A. Simultaneously with the application of the agent, pattern printing is performed by the printing plate roll 65B, and pattern printing is performed on the same surface as the deodorant application surface. In this case, the deodorant application surface and the printing surface are the same surface. As described above, when the deodorant is applied by the printing apparatus, the deodorant may be mixed with the colored ink. In particular, when a multicolor printing apparatus as shown in FIG. 7 is used, a deodorant may be mixed and applied in some colors of color ink for forming a pattern, You may make it mix a deodorizer in the coloring ink of this color.

  Further, in the embodiment of FIG. 8, a spray coating device, which is a deodorant application device 65A, is provided in the vicinity of the impression cylinder roll 65D of the roll transfer type printer 65, and the base paper immediately after leaving the impression cylinder 65C is provided. A deodorant is applied to the surface opposite to the printed surface. In this case, the deodorant imparting surface and the pattern printing surface are in a front-back relationship, and in particular, it becomes possible to manufacture a toilet roll having the deodorant imparting surface as the laminated inner surface and the pattern printed surface as the laminated outer surface.

  On the other hand, when applying a deodorant in the method for manufacturing a toilet roll of the present embodiment, it is used as a chemical solution containing a liquid or slurry deodorant suitable for application by each application device. In addition to the deodorant, the chemical solution containing such a deodorant may contain a solvent, an adhesive for fixing the deodorant as an active ingredient on the toilet paper base paper, ink, and other auxiliary agents. Examples of the solvent include water, alcohols, ethylene glycol, propylene glycol, butylene glycol, propyl alcohol, ethanol, methanol and the like. It is desirable to contain at least one of these, and in particular, water and a lower alcohol composed of at least one of propyl alcohol, ethanol, and methanol are preferably contained.

  As an adhesive agent, it can select in the range which does not prevent the effect of a deodorizer, For example, carboxymethylcellulose, polyvinyl alcohol, starch, etc. can be illustrated.

  Here, when polyphenol or the like is used as a deodorant, the polyphenol containing 0.1 to 40% by weight, preferably 0.5 to 20% by weight, particularly preferably 1.0 to 10% by weight of the polyphenol or the like is used. A chemical solution containing a deodorant can be obtained by appropriately mixing the above-mentioned adhesive, ink, a solvent such as water or lower alcohol, and other auxiliary agents with the system deodorant.

  In addition, the polyphenol-based deodorant liquid may contain an auxiliary agent such as a solvent such as water, a preservative, and a pH adjuster as other components other than the polyphenol. In addition, the polyphenol deodorant according to this embodiment includes other organic acids and organic acids for the purpose of stability, addition of functional groups to polyphenols, and further improvement of the deodorizing effect due to its own reactivity. A salt may be blended. Examples of the organic acid and organic acid salt include lactic acid, tartaric acid, malic acid, fumaric acid, succinic acid, citric acid, glutaric acid, amino acid, adipic acid, ascorbic acid, and inorganic or organic salts thereof. Examples of inorganic bases that form salts include alkali metal or alkaline earth metal hydroxides, oxides, carbonates, bicarbonates such as sodium, potassium, lithium, calcium, and magnesium. Examples of the organic base include nitrogen-containing bases such as compounds having groups such as primary, secondary or tertiary amines, imino groups, guanidino groups, imidazolino groups, imidazolyl groups and pyridyl groups.

  In addition, what is marketed can be used for a polyphenol type deodorizing liquid. For example, Pancil COS-15, Pancil COS-17, Pancil CL-10, Pancil AS-10, Pancil AS-20, Pancil BA-210-1, Pancil COS-5, Pancil FG-22 manufactured by Release Kagaku Kogyo Co., Ltd. Pancil FG-25, Pancil FG-30, Pancil FG-60, Pancil FG-70, Pancil FG-99, Pancil FX10, Pancil PO-10, Pancil BA-200E-1 can be used as appropriate.

  On the other hand, in the manufacturing method of the toilet roll of this embodiment, a well-known thing can be used for the winding device 66 which winds up the base paper 61. FIG. In the method for manufacturing a toilet roll of the present embodiment, when the base paper 61A is wound up to form the secondary raw roll 70, as shown in FIGS. It is desirable to wind it up. Since the deodorizer application surface 61A is not exposed on the outer peripheral surface of the secondary web roll 70 by winding in this way, when the secondary web roll 70 is discharged from the winding device 66, the next stage When transferring to the log forming step, the deodorant does not touch the equipment or the transfer equipment, and the iron member of the equipment or the transfer equipment is not oxidized by the deodorant.

(Log formation process (B))
In the method for manufacturing a toilet roll according to the present embodiment, a winder is formed in the log forming step (in FIG. 5B) in parallel with or after the manufacture of the long paper tube 30 and the secondary raw roll 70. The log 75 is manufactured by X2. Note that the log 75 is an intermediate product having the same diameter as that of the toilet roll as the final product and having a width more than a multiple of the final product. The long paper tube 30 manufactured in the paper tube forming step (A) is set on the winding portion 85 of the winder X2, and the toilet paper 7 having substantially the same width or slightly narrower than this is wound. To do.

  Toilet paper 7 wound around the long paper tube 30 is laminated in the winder X2 so that the base paper 71A, 71B fed from the secondary raw rolls 70A, 70B is such that the deodorant application surface is the inner surface of the laminate, It will form continuously.

  The illustrated form is particularly embossed in a form called so-called double embossing, which is disposed so as to face the toilet paper 7 to which embossing is applied, in particular, another base paper on which the convex portions of the embossing are laminated. An example is shown in which toilet paper 7 provided with is formed.

  In this embodiment, as shown in FIG. 9, first, when the two secondary raw rolls 70A and 70B manufactured in the secondary raw roll forming process are drawn out from the lowest point in the vertical direction, The face-to-face arrangement is such that the directions are different. At this time, as for the secondary raw fabric rolls 70A and 70B, the outer peripheral surface is a deodorant non-application surface as described above. Then, the base paper 71A, 71B is fed out from each of the raw rolls 70A, 70B, and immediately after that, the tension roll 8a is disposed so as to contact the deodorant non-application surface of the base paper 71A, 71B, and the tension is adjusted at the time of feeding. At the same time, the stacking guide roll 8b at the latter stage of the tension roll is primarily laminated so that the deodorant application surfaces 61A of the base papers 71A and 71B face each other, and conveyed downstream to provide embossing. To the embossing devices 20A and 20B. Thus, by delaminating the base paper 71A, 71B provided with the deodorant on the one side fed out from the secondary raw rolls 70A, 70B so that the deodorant application surface 61A faces, As long as the deodorant application surface 61A becomes the laminated inner surface and is conveyed in that state, the deodorant application surface 61A may be in contact with the guide roll even if the guide roll is arranged so as to contact the front or back surface of the sheet. Disappear.

  Further, in the illustrated embodiment, the base papers 71A and 71B are fed out from the lowest point in the vertical direction of the secondary raw rolls 70A and 70A. The guide roll configuration up to the overlapping guide roll 8b is not limited to the illustrated form. However, it is desirable not to arrange the iron guide rolls in the path leading to the overlapping guide rolls 8b.

  The base papers 71A and 71B in a state in which the deodorant application surface 61A is the laminated inner surface are peeled again immediately before the embossing devices 20A and 20B, and the base papers 71A and 71B are separately separated from each other. The embossing rolls 21A and 21B formed with a number of embossing projections corresponding to the above and the receiving rolls 22A and 22B that receive the embossing rolls 21A and 21B are guided to the embossing apparatuses 20A and 20B. Embossing is separately given to each of the base papers 71A and 71B through the base papers 71A and 71B between the rolls 21A and 21B and the receiving rolls 22A and 22B.

  In re-peeling the base paper, as shown in FIG. 9, the embossing device separates the base papers 71A and 71B from the immediately preceding guide roll 8c and guides them to the rolls constituting the embossing devices 20A and 20B, respectively. That's fine. However, if the guide roll 8d that contacts the deodorant application surface 61A of the base paper is necessary to guide it to the emboss application devices 20A and 20B, the conveyance path 8x may be arranged in such a manner. Of course, the guide roll 8d can be made of a material that is not oxidized by the deodorant.

  When the separated base papers 71A and 71B are separately supplied to the embossing device, as shown in FIG. 9, the base papers 71A and 71B are provided on the receiving rolls 22A and 22B whose deodorant application surface 61A has surface elasticity. Wrap it so that it faces the surface. And in the process of conveying on the receiving rolls 22A and 22B, the embossing rolls 21A and 21B are passed between the embossing rolls 21A and 21B so that embossing is applied, and the base papers 71A and 71B are wound around the embossing rolls 21A and 21B after the embossing is applied. In this state, it is transported downstream. If it does in this way, embossing can be provided, without making deodorant provision surface contact metal embossing rolls 21A and 21B.

  Moreover, in the manufacturing method of the toilet roll of this embodiment, When the base paper 71A is conveyed on the embossing roll 21A, the transfer roll arrange | positioned so that it may contact | connect only the top part of the embossing convex part of this embossing roll 21A. A laminating paste is applied to the surface of the base paper 71A by the roll transfer equipment 25A having the above. Since the base paper 71A is arranged on the surface of the embossing roll in a state of being deformed according to the surface irregularity shape of the embossing roll 21A by pressing at the time of embossing, in this way, the position of the top of the embossing convex part of the base paper 71A Only the laminate paste 29 is applied. A known laminate paste can be used.

  In the manufacturing method according to the toilet roll of the present embodiment, the base papers 71A and 71B thus embossed are separated from the embossing rolls 21A and 21B, and as shown in FIG. The deodorant application surface is made to face the base paper 71A (71B) which is fed from the other raw roll 70A (70B) and deodorized by the other emboss application device 20A (20B). The toilet paper 7 is laminated and a deodorant is applied to the inner surface of the laminate. In particular, in the manufacturing method according to the illustrated example of the toilet roll, since the laminate paste 29 is applied to the top of the embossed convex portion of one base paper 71A, each base paper 71A, 71B is laminated and integrated with the laminate paste 29. Into toilet paper.

  In the illustrated example, the base paper 71B separated from one embossing roll 21B is guided to the marriage roll 23 arranged adjacent to the other embossing roll 21A, and laminated and integrated on the marriage roll 23. . However, the embossing rolls 21A and 21B are arranged close to each other so that the peripheral surfaces thereof face each other, and the base papers 71A and 71B are erased at positions where the peripheral surfaces of the embossing rolls 21A and 21B face each other. The odorant-applied surface may be attached and laminated and integrated.

  As for the aspect of the laminated integration, as shown in FIG. 10B, the so-called “Tip To Tip” of the embossed convex portions 26A and 26B of the base papers 71A and 71B is made to face each other. The embossed protrusions may be stacked in a so-called “Nested” form in which the tops of the embossed convex portions do not face each other. These can be implemented by selecting an emboss pattern for “Tip To Tip” and “Nested”. In FIG. 10, deodorant application positions are indicated by reference numerals 27A and 27B.

  However, in manufacturing the toilet roll of the present invention, the present invention is not limited to the illustrated form. For example, the primary roll 60 for forming the secondary roll is a roll obtained by winding a sheet laminated in advance. You may manufacture as. Further, if there are three or more original rolls, and each base paper is fed out and laminated primarily so that the deodorant imparting surface does not become the outer surface, a three-ply or more can be manufactured. Furthermore, some of the plurality of secondary web rolls set in the winder can be not provided with a deodorant, and in this case, a toilet paper base paper provided with a deodorant, Toilet paper in which toilet paper base paper to which a deodorant is not applied is laminated and integrated is obtained.

  Moreover, in the manufacturing method concerning the toilet roll of this embodiment, after each base paper 71A, 71B is unwound from each raw fabric roll 70A, 70B, after being laminated | stacked once by the superimposition guide roll 8b, embossing apparatus 20A, 20B In the present invention, each emboss is formed without temporarily laminating each of the base papers 71A and 71B from the raw rolls 70A and 70B. It may be separately guided to the applying devices 20A and 20B and wound around the surface elastic receiving rolls 22A and 22B.

  Furthermore, in the present embodiment, embossing is performed on each of the base papers 71A and 71B fed from the raw fabric rolls 70A and 70A. However, only one base paper is embossed using only one embossing device. You may make it provide.

  Moreover, in the manufacturing method of the toilet roll of this embodiment, after feeding each base paper 71A, 71B from each raw fabric roll 70A, 70B, after laminating | stacking once with the superimposition guide roll 8b, it is a toilet as it is, without providing embossing. Paper 7 may be used. In this case, the toilet paper is not given emboss. Further, after each base paper 71A, 71B is fed out from each of the original fabric rolls 70A, 70B and laminated once with the superposition guide roll 8b, embossing is imparted by a single embossing device in the superposed state, It is good also as the toilet paper 7 of the aspect of what is called a single embossing in which the embossing convex part is formed in one surface, and the recessed part corresponding to the convex part is formed in the other surface.

  After forming the toilet paper 7 by laminating the base papers 71A and 71B as described above, in the present embodiment, the perforation line is formed by the perforation line forming device 82, and thereafter, the winding part 85 is long. It is wound around a paper tube 30 to form a 2-ply log. However, it is not essential to provide the perforation line forming device and the perforation line. Further, in the present embodiment, although not shown, a known contact embossing device may be provided before the perforation line applying device 82 to provide the contact embossing.

  The toilet paper 7 according to the present embodiment is formed by contacting the deodorizer application surface with a metal embossing roll or a guide roll installed in the winder in a series of log manufacturing steps in the winder X2. Without making it, since the toilet paper by which the deodorizer provision surface was made into the lamination | stacking inner surface is formed continuously, productivity of a toilet roll is not reduced. Moreover, there is no possibility that the metal member of the facility is oxidized, corroded, discolored, or damaged until embossing is applied from the raw roll to make toilet paper. The trouble of cleaning the equipment due to the adhering deodorant is also reduced.
