Abstract

[PROBLEMS] To easily manage the amount of deodorant and fragrance used in coreless toilet paper.
After applying a deodorant or a fragrance to the outer peripheral surface of a winding shaft, a paper P of toilet paper is wound around the winding shaft, and the winding shaft is removed from a roll R of the wound paper. The manufacturing method of coreless toilet paper to be extracted was adopted. Since the deodorant and the fragrance are applied to the winding shaft 10, the deodorant and the fragrance can be attached to the paper P of the toilet paper wound around the outer periphery thereof. This makes it possible to apply the deodorant and the fragrance separately from the adhesive application process for forming the core portion around the winding shaft 10 and to easily manage the amount of the deodorant and the fragrance. . In addition, deodorants and fragrances adhere only to the innermost part of the wound roll and the paper layer in the vicinity of the roll. High deodorizing effect and aroma effect can be expected with a small amount of medicine.

Description

  The present invention relates to a toilet paper manufacturing method and a toilet paper manufacturing apparatus used for carrying out the manufacturing method.

  In general toilet paper, a cylindrical body made of cardboard is interposed at the center thereof, and the toilet paper is wound around the outer periphery of the core material using the cylindrical body as a core material. This type of toilet paper is also called cored toilet paper.

  On the other hand, there is a coreless toilet paper that does not use a core material. In coreless toilet paper, the toilet paper supplied from the roll is sprayed with adhesive on several layers at the beginning of the roll wound on the winding shaft, and the cores are fixed by solidifying the several layers. Forming. The winding shaft is pulled out in the axial direction after the roll of the toilet paper roll is completed.

  By the way, in recent years, there are products in which a core material or toilet paper itself contains a deodorant or a fragrance.

  For example, Patent Document 1 is an example of toilet paper with a core, in which a fragrance is applied in advance to the outer surface of the core material, and then the paper of the toilet paper is wound around the outer periphery of the core material.

  Patent Document 2 is an example of a coreless toilet paper, in which a chemical solution such as a deodorant or a fragrance is contained in an adhesive for forming a core part. That is, immediately before the paper of toilet paper supplied from the raw fabric roll is wound around the winding shaft, the adhesive containing the chemical solution is jetted.

  According to the above-described method of adding a deodorant or a fragrance to the adhesive for forming the core part, there is a problem that it is difficult to adjust the amount of the deodorant or the fragrance used. That is, since the adhesive forming the core is continuously sprayed over several layers at the beginning of winding, a considerable amount of deodorant and fragrance is sprayed accordingly. . It is desirable that the amount of the deodorant or fragrance used is appropriately controlled from the viewpoints of maintaining a pleasant scent and cost.

  Accordingly, an object of the present invention is to make it possible to easily manage the amount of deodorant and fragrance used in the coreless toilet paper.

  In order to solve the above-described problems, the present invention relates to a method for manufacturing a coreless toilet paper in which toilet paper is wound around a winding shaft, and then the winding shaft is removed from a roll of the wound paper. After applying a deodorant or a fragrance to the outer peripheral surface of the paper, a configuration was adopted in which toilet paper was wound around the winding shaft.

  If a deodorizing agent or fragrance is applied to the winding shaft, the deodorizing agent or fragrance adheres to the paper of toilet paper wound around the outer periphery. For this reason, a deodorant and a fragrance | flavor can be apply | coated separately from the application | coating process of the adhesive agent for forming a core part around a winding axis. Therefore, management of the amount of deodorant and fragrance is easy.

Further, the deodorant and the fragrance are attached only to the innermost portion of the wound roll, that is, the innermost layer facing the hollow portion formed after extracting the winding shaft and the paper layer in the vicinity thereof. For this reason, a deodorant and a fragrance | flavor can be made to adhere only to the part which is relatively easy to touch air, and a high deodorant effect and a fragrance effect can be expected with a small amount of chemicals.
In general, the core portion hardened with an adhesive extends from the innermost layer to several to several tens of layers. However, in the conventional technique, the deodorant and the fragrance adhering to the portion of the core portion that is relatively far from the innermost layer did not contribute much to the deodorant and fragrance effects.

  For the application of the deodorant or the fragrance to the winding shaft, for example, a method of injecting a solution (for example, an aqueous solution) of the deodorant or the fragrance onto the outer peripheral surface of the winding shaft can be adopted. In addition, for example, a winding shaft is immersed in a deodorant or fragrance solution, or a brush, cloth, sponge, or other material with a deodorant or fragrance solution attached is used as a winding shaft. You may make it contact.

  In these configurations, if a configuration in which a plurality of protrusions extending in the axial direction are provided in parallel on the outer peripheral surface of the winding shaft, the contact area between the outer peripheral surface of the winding shaft and the paper of the toilet paper increases. For this reason, a higher deodorizing effect and fragrance effect can be expected with a limited amount of the deodorant and fragrance.

  In these configurations, the process of winding toilet paper on the winding shaft, and then repeatedly removing the winding shaft from the rolled paper roll is performed in the axial direction when the winding shaft is extracted from the roll. It is possible to employ a configuration in which a deodorant or a fragrance is applied to the winding shaft, and then toilet paper is wound around the winding shaft on which the deodorant or fragrance is applied.

  In the normal manufacturing process, the toilet paper is wound around the winding shaft, and then the step of extracting the winding shaft from the rolled paper roll is repeated, so when removing the winding shaft from the roll in the previous stroke, It is efficient to apply a deodorant or fragrance corresponding to the roll of the next step to the winding shaft. When the winding shaft is extracted from the rolled paper roll, the roll and the winding shaft move relative to each other in the axial direction. Therefore, by using the relative movement, the medicine is predetermined along the axial direction of the winding shaft. It is because it can be easily applied to the range of the above.

The following configuration can be adopted as a toilet paper manufacturing apparatus for carrying out the manufacturing method of the coreless toilet paper having the respective configurations.
That is, a paper supply unit in which a raw roll is disposed, a winding shaft around which toilet paper supplied from the paper supply unit is wound, and a roll of paper wound around the winding shaft. Manufacture of a coreless toilet paper comprising a moving means for moving the winding shaft and the roll relative to each other in the axial direction in order to extract the odor, and a medicine applying means for applying a deodorant or fragrance to the outer peripheral surface of the winding shaft Device.

  The drug application means may employ a configuration in which a deodorant or a fragrance is applied to the outer peripheral surface of the winding shaft when the winding shaft and the roll are relatively moved in the axial direction by the moving means. .

  In this invention, since the deodorant and the fragrance are applied to the winding shaft, the deodorant and the fragrance can be attached to the paper of the toilet paper wound around the outer periphery thereof. This makes it possible to apply the deodorant and the fragrance separately from the adhesive application process for forming the core part, and the amount of the deodorant and the fragrance is easily managed.

  Further, the deodorant and the fragrance are attached only to the innermost portion of the wound roll, that is, the innermost layer facing the hollow portion formed after extracting the winding shaft and the paper layer in the vicinity thereof. For this reason, a deodorant and a fragrance | flavor can be made to adhere only to the part which is relatively easy to touch air, and a high deodorant effect and a fragrance effect can be expected with a small amount of chemicals.

The principal part expansion perspective view which shows the positional relationship with the roll and winding axis | shaft of wound paper, and a nozzle (A) is a principal part expansion perspective view which shows the state which is injecting the chemical | medical solution to a winding shaft, (b) is the sectional drawing, (c) is a principal part enlarged view of the roll of a toilet paper.

  Hereinafter, the manufacturing method of the coreless toilet paper of this invention and the structure of the manufacturing apparatus for implementing the manufacturing method are demonstrated.

As shown in FIG. 1, the manufacturing apparatus has a paper supply unit (left side in the figure) on which a raw roll Q is disposed, and a roll of paper P of toilet paper supplied from the paper supply unit. A winding unit (center in the figure) in which the shaft 10 is disposed, and a receiving unit (see FIG. 5) that receives the rolled roll R when the paper roll _R0 wound around the winding shaft 10 reaches a predetermined winding thickness. Middle right).

  In the paper supply unit, an original fabric roll Q around which paper P of toilet paper having a predetermined width is wound is supported so as to be rotatable about its axis.

In the winding unit, toilet paper P supplied from the paper supply unit is guided to the winding shaft 10 through predetermined rollers 1, 2, 3, and the like. The reference numeral 2 and 3 hold the roller in the drawing, reference numeral 1 denotes a pressing roller which moves up and down in accordance with the variation in the winding thickness of the roll R _0.

  The front end of the paper P of the toilet paper is locked to the winding shaft 10, and the winding shaft 10 rotates around the shaft by the driving force, whereby the paper P of the toilet paper is wound around the winding shaft 10. Here, the fragrance has already been applied to the outer peripheral surface of the winding shaft 10 in advance. The method of applying the fragrance and the structure of the application device will be described later.

  The arrangement and driving method of each roller can be determined as appropriate according to the specifications. For example, the rotation of the winding shaft 10 may drive the holding rollers 2 and 3 or the pressing roller 1 by an electric motor or the like. Further, the winding shaft 10 may be driven directly. Or you may selectively combine the drive of each of these rollers.

  Water as an adhesive is sprayed from the adhesive spray nozzle 4 to several layers at the beginning of winding of the paper P wound around the winding shaft 10. By this water injection, several layers at the beginning of winding are hardened to form a core portion around the winding shaft 10. This solidified winding core plays the same role as the core material of the cored torette paper. In this embodiment, water is used as the adhesive, but a drug solution having an adhesive function may be sprayed.

Further, in the winding unit, when the paper roll R ₀ wound around the winding shaft 10 reaches a predetermined winding thickness, a cutting means (not shown) for cutting the paper P supplied from the raw roll Q. )). As the cutting means, for example, a cutter or the like can be provided at the front stage of the roller 2 (the original roll Q side).

  The receiving unit has a function of receiving the roll R that has reached a predetermined winding thickness after the paper P is cut by the cutting means. The roll R is guided to the receiving portion by an inclined guide 5 or the like, and is placed on a holding roller indicated by reference numerals 12 and 13 in the drawing.

  The receiving portion includes a moving means 15 that relatively moves the winding shaft 10 and the roll R in the axial direction. In this embodiment, as shown in FIG. 2, the moving means 15 is an endless chain or belt, and a bracket 14 is attached to the moving means 15.

  In the receiving part, the roll R moves together with the winding shaft 10 from the receiving state shown in FIG. 2A (the state received from the winding part) to the unloading preparation state shown in FIG. 2B (from the receiving state to the side). Move to the ( This movement is performed by engaging the engaging portion 14a of the bracket 14 with a recess 10a provided at one end of the winding shaft 10 and operating the moving means 15 with a driving force of an electric motor or the like in this state. The bracket 14 pushes the tapered surface forming a part of the concave portion 10 a of the winding shaft 10, and the roll R moves together with the winding shaft 10.

  Next, in order to extract the winding shaft 10 from the roll R, the presser plate 16 is advanced to the end of the roll R. The presser plate 16 moves from the state shown in FIG. 3 to the state shown in FIG.

  When the holding plate 16 has advanced to the end of the roll R, the moving means 15 operates to move the bracket 14 in the opposite direction, that is, in the direction of the arrow shown in FIG. Thereby, the bracket 14 pushes the flange 11 at the end of the winding shaft 10, and the winding shaft 10 is extracted from the roll R. At this time, since the end of the roll R is held by the presser plate 16, the roll R does not move and only the winding shaft 10 moves.

  In addition, the receiving unit includes a drug application unit 20 that applies a fragrance to the outer peripheral surface of the winding shaft 10 when the winding shaft 10 and the roll R relatively move in the axial direction. In this embodiment, a nozzle for injecting a fragrance solution is employed as the medicine application means 20, and the nozzle is fixed to the presser plate 16. For this reason, as the roll R is held by the presser plate 16 and the winding shaft 10 is pulled and moved by the bracket 14, the aqueous solution of the fragrance is sprayed along the axial direction on the outer peripheral surface of the winding shaft 10. Can do. In this embodiment, the medicine application means 20 also serves as means for applying a lubricant to the outer periphery of the winding shaft 10 and a mixture of fragrance and lubricant is jetted from the nozzle. The means for applying and the medicine applying means 20 may be provided separately. At this time, the means for applying the lubricant sprays the lubricant to the outer periphery of the winding shaft 10 in order to make it easy to extract the winding shaft 10 from the roll R, and the medicine applying means 20 It can be configured to inject.

  The wound winding shaft 10 is sent to the winding section, and in the next step, the toilet paper is wound around the winding shaft 10 so that the fragrance is attached to the next roll R. Become. Hereinafter, this process will be repeated.

  The roll R from which the winding shaft 10 has been extracted is carried out to the next process, and if necessary, is cut into a predetermined length in the axial direction to complete a coreless toilet paper.

  As shown in FIG. 4 (b), if a configuration in which a plurality of axially extending protrusions 10b are provided in parallel on the outer peripheral surface of the winding shaft 10, the outer peripheral surface of the winding shaft 10 and toilet paper is provided. The contact area with the paper P (corresponding to the inner surface of the hollow portion of the roll R formed after the winding shaft 10 is extracted) increases. For this reason, a higher deodorizing effect and fragrance effect can be expected with a limited amount of the deodorant and fragrance.

  FIG. 4C shows the roll R after the winding shaft 10 has been extracted. As for this roll R, the unevenness | corrugation corresponding to the protrusion 10b has arisen in the inner surface of the core part, and the area which contacts air is large compared with the case where it is a cylindrical surface without an unevenness | corrugation. Thereby, a higher fragrance effect can be expected.

  In this embodiment, the fragrance solution is jetted onto the winding shaft 10. However, instead of the fragrance, a deodorant or a medicine containing both the deodorant and the fragrance may be applied. Good. In this embodiment, the nozzle as the medicine applying means 20 is fixed to the presser plate 16, but the nozzle installation position may be other than the presser plate 16. That is, it is only necessary that the medicine can be applied to the outer peripheral surface of the winding shaft 10 that moves relative to the roll R in the axial direction.

  Further, as the medicine application means 20 other than the nozzle, as the winding shaft 10 moves in the axial direction, a brush, cloth, sponge, or other material to which a deodorant or fragrance solution is attached is brought into contact with the winding shaft 10. It is good also as a structure. Conversely, the drug application means 20 having these components may be moved in the axial direction with respect to the winding shaft 10. Or you may provide the apparatus which immerses the winding shaft 10 in the solution of a deodorizer or a fragrance | flavor.

  The deodorant and the fragrance are preferably applied over the entire circumference of the winding shaft 10, but the medicine is applied only in a part of the direction along the circumferential direction of the outer peripheral surface. Even if it is, a predetermined effect can be expected.
