Abstract

PROBLEM TO BE SOLVED: To reduce a stock area, to increase a transportation amount and to reduce a display area in a store by reducing a roll diameter without changing the basis weight and roll length of toilet paper and also without losing flexibility. SOLUTION: The inner diameter of a paper tube 3 to be used as a core is made to be a little larger than the outer diameter of the support bar of a holder at the time of usage, toilet paper 2 is rolled up by rolled toilet paper 1 while being pressurized to the support rolls 4 and 4 of a roll-up device by a pressed roll 6 at the time of single rolling and an embossed roll is used as the pressed roll 6 as necessary. At the time of double rolling, toilet paper 2 is obtained by superimposing the one made by using bleached pulp for paper manufacture or/and high quality collected waste paper pulp which does not includes printed matters on the one made by low class collected waste paper pulp which is collected from low class waste paper including the collected printed waste paper, etc., so as to be ink-removed and bleached and, then, toilet paper 2 is rolled-up in a roll shape by being pressed by an embossing device or by using the pressed roll 6 of the embossed roll.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-shaped toilet paper which is made by using papermaking pulp as a main raw material and wound up while being cut to a required width.

[0002]

2. Description of the Related Art Toilet paper has conventionally been made from recycled pulp using waste paper and cut into a square shape.
Roll-shaped toilet paper that has been rolled up into a long length while cutting toilet paper made from unused bleached pulp as a main raw material into a required width has come into wide use.

[0003] As described above, roll-shaped toilet paper has come to be widely used in general homes and business establishments.
According to Japanese Industrial Standards, the paper width is 114 mm and the roll diameter is 120 mm or less.However, in general, a paper cylinder with an inner diameter of 38 mm is used as the core because of the structure of the cutting and winding finisher, and it is flexible and easily dispersed in water. In order to reduce the beating degree of the raw material pulp, creping is performed during the papermaking process, etc.
When stacking, wrap it softly around a length of 32.5m,
It is finished so that the diameter is less than 120 mm and about 115 mm.

Recently, a paper tube used as a core does not disperse in water, so it has to be disposed of separately as dust. A paper tube made of water-soluble paper that dissolves when poured into water has to be manufactured and used. In addition, a coreless roll of toilet paper without a core has been developed.
No., No. 54-43963, No. 6-47357
It has been proposed and published on the market.

[0005]

Toilet paper wound into a roll is packed in a cardboard box and delivered to a store or a large customer in order to keep the roll from deforming and maintaining flexibility. Warehouse storage, transportation, there is a problem such as a large necessity for the value such as the display volume at the store, and as described above, the coreless toilet paper has been sold, and the winding length is 100m to 110m. Cost reduction has come to be measured such as lengthening, but in the case of non-core, the core rod of the conventional roll-shaped toilet paper holder can not be used, so it is necessary to replace it with a special core rod,
It is necessary to attach a coreless rod for each product packaging unit.

[0006] In order to reduce the volume during transportation, the actual open flat 7 is used.
As disclosed in Japanese Patent Publication No. 25894, a method has been proposed in which a roll-shaped product is pressure-bonded from the side to crush the paper tube of the core and flatten it, but it is necessary to restore the product to a cylindrical shape when used. However, the core of the paper core may be deformed without being restored to a completely cylindrical shape, and the shape of the toilet paper may also be deformed. Although the volume has been shortened and the winding length has been shortened, and even the softness has been somewhat impaired, it has been practiced to wrap it hard and reduce the diameter, but at least the roll-shaped toilet paper of the same length In such a case, there has been a demand for a product having a small roll diameter and not losing softness.

Recently, toilet paper made from recycled pulp has come to be used due to the problem of reuse of recycled paper, but pulp recovered from printed waste paper such as magazines is deinked. Also, the whiteness is poor, and the pulp fibers include those that are finely cut and beaten for use as printing paper, so when recycled as toilet paper it does not come out bulkier than when using new pulp,
It has the disadvantage of lacking flexibility and has the advantage of reducing the diameter when rolled, but has the problem of being less favored by consumers. No recycled waste paper is used, and high-grade recovered waste paper pulp is used, such as milk packs and high-quality paper cuttings that do not include the printing section. For this reason, the use of toilet paper made from low-grade recovered waste paper pulp including printed matter has been desired.

[0008]

The present invention has been made as a result of various studies in order to answer such a demand and to solve the problems. A current roll-shaped toilet paper is cut and rolled up by a roll winding machine. Due to the structure of the paper core, the diameter of the paper tube used for the core is about 38 mm, the diameter cannot be made smaller than that, and the support rod of the holder for installing the rolled toilet paper at the time of use at the customer must have a diameter of 25mm
Is the standard, so the core paper core that can be used for the support rod has a minimum inner diameter of about 28 mm, and when the toilet paper is wound around the paper core in a roll winding machine, the paper core is supported by two pressure rolls. By improving the structure so that it is wound up into a roll while being pressed against a roll, a roll having a length of 65 m and a diameter of about 90 mm can be obtained. Further, by using an embossing roll as the pressure bonding roll, it is possible to provide a soft-feeling toilet paper by rolling up the entire surface of the toilet paper while making a difference in the pressing force due to unevenness.

[0009] In the case of two sheets, toilet paper using bleached pulp for papermaking and toilet paper using low-grade recovered paper pulp such as magazines are overlapped and rolled up while being pressed on an embossing roll to reduce the diameter of the roll. By arranging the toilet paper using the bleached pulp for papermaking on the front side, it was possible to obtain a two-ply toilet paper having good appearance and good flexibility by positioning the toilet paper using a bleached pulp for papermaking on the front side. Things. In this case, the bleached pulp for papermaking may be made of recycled bleached pulp other than unused bleached pulp for papermaking, as well as carton for milk and cutting waste that does not include the printing part of high-quality paper. After laminating toilet paper and toilet paper made of low-grade recovered waste paper, it is allowed to pass through the gap between the embossing roll and the elastic roll, and then cut and rolled up while being pressed with the roll.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. (Example 1) Rolled toilet paper of the present invention
As shown in FIG. 2, the winding device (1) includes a paper tube (3) serving as a core rotated by two support rolls (4) and (4).
Is held by a winding shaft (5) which is inserted through a paper tube (3) and freely moves up and down, and is supported by a pressure roll (6) and a support roll (4),
It is configured to rotate while being pressed against (4).

The diameter of the winding shaft (5) is about 25 mm and the inner diameter is about 2 mm.
The paper tube (3) can be easily inserted through an 8 mm paper tube (3), and the paper tube (3) is rotated by two pressure rolls (6).
The toilet paper (2), which is pressed and rotated against (4) and cut to a required width, is wound around the paper tube (3). At this time, it is preferable to use an embossed roll for the pressing roll (6) so that a difference in the pressing pressure can be caused by the unevenness of the embossing when pressing the toilet paper, and the diameter and gap of the supporting rolls (4) and (4) are good. Is a paper tube with an inner diameter of about 28 mm (3)
It is adjusted to support and rotate.

Using the winding apparatus adjusted as described above, one sheet of crepe-attached toilet paper made from a bleached pulp for papermaking as a raw material and formed to a basis weight of 18.2 g / m ^{2 according} to a conventional method. It was rolled up to a length of 65 m to obtain a roll of toilet paper. The diameter of the obtained roll-shaped toilet paper is 90 mm, which is about 15 mm more than the conventional product.
It was finished small and the softness during use was not different from the conventional product.

(Embodiment 2) Using the same winding device as in Embodiment 1, an embossing roll is used for the pressure roll (6), and a bleached pulp for papermaking is made of a milk pack containing no printed waste paper and a high quality paper made of high quality paper cutting waste paper. Equal amounts of recovered pulp are blended, and creped toilet paper (hereinafter referred to as high-quality crepe toilet paper) is formed to a basis weight of 18.0 g / m ^{2 according} to a conventional method, and printed materials such as used magazine paper. The waste paper containing waste paper is deinked and bleached, and crepe-containing toilet paper (hereinafter referred to as crepe-containing toilet paper including printed waste paper) made of lower-grade recovered waste paper pulp as a main raw material and formed to a basis weight of 18.5 g / m ² . And the inside diameter of the crepe toilet paper should be
The paper was wound into a roll with a roll length of 32.5 m while being pressed against an embossed pressure roll (6) on a paper tube of mm to obtain a roll of toilet paper having a diameter of 90.5 mm.

[0014] Further, an embossing device comprising an embossing roll and a rubber roll is provided in the winding device, and a pressing roll is provided.
In (6), a high quality toilet paper with crepe and a toilet paper with crepe including printed waste paper are superimposed on each other using a normal smooth roll. When rolled up on a paper tube, a roll of toilet paper having a diameter of 89.5 mm was obtained.

[0015]

As described above, the roll-shaped toilet paper according to the present invention is wound up to the same length using the same toilet paper as described above.
20mm smaller, so if the same number is packed, the bottom area will be smaller on both sides, so it will be smaller than conventional products, the storage area at the time of stock is small, the transport volume at the time of delivery is increased, and the exhibition area of the store is The economic effects, such as a decrease, are significant.

Also, in the case of double stacking, by stacking high quality toilet paper and toilet paper made of lower grade waste paper pulp including printed waste paper and the like, the conventional double stack of high quality toilet paper is larger in diameter than the single stack. Although it was easy to increase the size, it could be rolled up as small as about 90 mm, almost the same as a single stack, and good quality toilet paper was put out on the front side and pressed with an embossing roll, so that it had the same appearance as the conventional product It is soft and can be provided to consumers at low cost, and has effects such as being able to help reuse of used paper. Furthermore, as a result of reducing the inner diameter of the paper core of the winding core, there is also an effect that it can be taken out smoothly without any risk of rattling during use even though it is slightly deformed. Further, since the diameter is 90 mm, handling such as mounting on a holder is extremely easy.
