Description

  The present invention relates to a method for identifying the origin of a tubeless toilet roll.

  Toilet rolls wound with long toilet paper include a so-called cored type in which toilet paper is wound around a tube core called a paper tube and a tubeless type without a tube core (this tube The coreless type is sometimes simply called coreless or coreless)

  Here, in the toilet roll with a tube core, origin information such as a manufacturer name, a lot number, a production date, and a production factory name is printed on the inner peripheral surface of the paper tube. This is to make it possible to identify the manufacturer name, lot number, production date, production factory and the like based on the origin information of the toilet roll when the toilet roll distributed outside the production factory is returned.

  However, in the case of a toilet roll without a tube core, the above-mentioned origin information cannot be given, and when returned, the manufacturer name, lot number, production date, and production factory of the toilet roll cannot be identified.

  Here, in the toilet roll, embossing may be given to the toilet paper, and since this embossing pattern is different in each manufacturer, it is considered that the manufacturer is identified by this embossing pattern. It is done. However, since a toilet roll without a tube core is often an inexpensive product containing waste paper, there are many products that are not given added value such as embossing, and there are many products that cannot be identified by an embossed pattern. Further, in the emboss pattern, only the above-mentioned production degree can be identified, and the lot number, production date, and production factory cannot be specified.

Toilet roll without tube core that has the feature of identifying origin information.

  According to the present invention described above, the manufacturer name, lot number, production date, production factory, and the like of the toilet roll without a tube core can be identified after shipment.

It is the schematic of the toilet roll without a pipe core concerning this invention. It is a figure which shows the example of a manufacturing apparatus of the toilet roll without a pipe core concerning this invention. It is a figure which shows the manufacturing method of the toilet roll without a pipe core concerning this invention.

Hereinafter, a method for identifying the origin of a toilet roll without a core according to the present invention will be described in detail with reference to the drawings.
The toilet roll X1 according to the source identifying method of the present invention is a tubeless toilet roll X1 having no tube core, also referred to as a so-called paper tube (hereinafter also simply referred to as a toilet roll), as shown in FIG. The core portion 1 is formed by fixing the toilet paper itself constituting the toilet roll X1 with adhesive glue. And in the toilet roll X1 which concerns on the invention, the discriminating agent which colors with respect to at least one of the light of a predetermined wavelength, and a reagent is mixed in the adhesive paste which has fixed the core part 1. FIG.

  The toilet roll X1 according to the source identifying method of the present invention will be described in detail together with the manufacturing method. The manufacturing method is as follows. First, as shown in FIG. 2, a roll of toilet paper 2 that is longer than a product width of the toilet roll X1 and is longer than the roll width of the toilet roll X1 is unwound from the raw roll JR manufactured by the papermaking equipment. Ends are placed on the pair of winding rollers 31, 31. At this time, the front end 2t of the toilet paper base paper is positioned further downstream than the downstream winding roller so as to be exposed from the winding roller.

  Thereafter, as shown in FIG. 3 (A), the core shaft 30 is moved downward from above, the toilet paper base paper is interposed between the core shaft 30 and the take-up rollers 31, 31, and The core shaft is supported by the pair of take-up rollers 31 and 31 in a state where the distal end portion 2 t is exposed to the downstream side of the core shaft 30.

  Next, as shown in FIG. 3B, compressed air A or the like is sprayed onto the tip 2t from below by a folding means 32 such as an air nozzle so that the tip 2t is wound around the core shaft 30.

  If the tip 2t of the toilet paper base paper 2 is folded and wound around the core shaft 30, the adhesive paste S is sprayed from the spray means 33 toward the core shaft 30 as shown in FIG. The core shaft 30 is rotated while performing, and the end portion of the toilet paper base paper 2 is temporarily fixed to an appropriate length to form the core portion 1.

  After the core portion 1 is formed in this way, as shown in FIG. 3D, a take-up device, also referred to as a rider roll 34, is brought into contact with the temporary fixing portion (core portion 1) and rotated so that the toilet roll. The toilet roll base paper 2 is wound around the core shaft 30 until the product diameter is reached.

  The core shaft 30 generally has a substantially round cylindrical shape, a hollow or solid rod shape, a cross-sectional diameter of about 5 to 50 mm, and a length of about 1 to 3 m. is there. The material of the shaft is not limited, but is made of metal, particularly stainless steel, and SUS304 is most preferably used.

  After the toilet paper base paper 2 is wound around the core shaft 30 to the product diameter of the toilet roll, it is not shown between the toilet paper base paper from the raw roll JR and the toilet roll base paper wound around the core shaft 30. It cuts off with a cutter means etc., the paste for tail seal is attached to the cut-off end part, and it adheres to the cylindrical part currently wound around core shaft 30. This operation is also called a tail seal. In FIG. 1, the tail seal portion is denoted by reference numeral 3. As the tail seal paste, water or an aqueous adhesive such as polyvinyl alcohol can be used, respectively, or mixed.

  In this way, after the toilet paper base paper 2 is wound around the core shaft 30 around the product diameter of the toilet roll, the core shaft 30 is pulled out in the direction perpendicular to the rotation direction, that is, the axial extension direction of the core shaft 30. It is a so-called log which is the diameter of the product of the roll X1 and is a multiple of the product width of the toilet roll X1.

  After manufacturing this log, it is trimmed to an appropriate size in the width direction with a log cutter (not shown), for example, both ends of the log, and then cut into a product width to obtain a toilet roll X1.

  Here, in manufacturing the tube coreless toilet roll X1 according to the source identifying method of the present invention, as described above, the light having a predetermined wavelength is characteristically applied to the adhesive paste S for forming the core portion 1 as described above. And at least one of the reagents is mixed with a color-determining drug. By mixing the identification drug in this way, even after the product is shipped to the market, the toilet roll X1 irradiates the core portion 1 with light of a predetermined wavelength corresponding to the identification drug, Or it can be made to react and color by dripping a reagent.

  In addition, as an adhesive paste for forming the core, water or an aqueous adhesive paste such as polyvinyl alcohol can be used individually or mixed. The discriminating agent is preferably colorless and transparent in a state where at least one of the light having the predetermined wavelength and the reagent is not colored.

  Specific examples of discriminating agents include esculin, diaminostilbenzenesulfonic acid, bis (triazinylamido) stilbenzylsulfonic acid, coumarin derivatives, pyrazoline derivatives, fluorescent latex, and fluorescent dyes such as Kayaphor EXN Liquid manufactured by Nippon Kayaku Co., Ltd. , Thymolphthalein (bromothymol blue), phenolphthalein, phenol red, cresol red, starch and the like. The discriminating agent mixed with the adhesive paste can be used in combination of not only one type but also a plurality of types as appropriate. For example, both a fluorescent dye and thymolphthalein may be mixed. If a fluorescent dye is used, a general one may be used, but a highly safe medical one is desirable.

  If it is the said fluorescent dye, it can be made to color so that it may light-emit by irradiating with the long wavelength ultraviolet-ray also called what is called a black light. In the case of thymolphthalein, an acid or alkali reagent can be dropped and colored. If it is phenolphthalein, it can color by dripping an alkaline reagent. Furthermore, if it is starch, it can be made to color by dripping iodine as a reagent. In addition, the combination of an identification agent, a reagent, and light is not limited to the said example.

  Moreover, the mixing amount of the discriminating agent with respect to the adhesive paste is not particularly limited, but the mixing ratio is such that the coloration can be sufficiently visually confirmed. As a specific example, if it is the said fluorescent dye, what was diluted about 100 times should just mix 5-20 weight part with respect to 100 weight part of adhesive paste. However, when the amount is less than 5 parts by weight, it is not preferable because there is a possibility that coloring is not possible to the extent possible by visual observation. When the amount is more than 20 parts by weight, the toilet paper base paper is discolored, which is not preferable. .

  Here, in the manufacturing method of the toilet roll X1 according to the source identification method of the present invention, not only the adhesive paste S is mixed with the identification drug, but also the identification drug is manufactured in a manufacturing factory, a manufacturing apparatus, and a production lot. The production date, production time, product type, etc. should be different for each given product origin unit.

  For example, for products manufactured during the period from ** month * day to △ month △ day, starch is used as the identification drug, and those manufactured during the period from × month x day to ◎ month ◎ day are used as the identification drug. Use phenolphthalein. In addition, for example, thymol blue is used as an identifying agent for those manufactured at the A factory, and phenolphthalein is used as an identifying agent for those manufactured at the B factory. In this way, each time the place such as the place and the producer differs, the identification drug is made different so as to correspond.

  In addition, the origin in this invention shall mean at least the manufacturing factory of the said example, a manufacturing apparatus, a manufacturing lot, a production date, the time of production, and a product kind.

  The tubeless toilet roll X1 according to the method of identifying the origin of the present invention thus manufactured is used as a reagent or a reagent for the core portion of the toilet roll returned from the consumer for some reason after production such as shipment to the market. By irradiating light of a predetermined wavelength, it is possible to specify the place, the origin of the producer, etc. at the time of the toilet roll. For example, when the reason for the return is a defective product, it is possible to specify the cause of occurrence, the place of occurrence, the generation device, the date and time of generation, etc., and it is possible to improve the quality quickly. .

  In particular, in the toilet roll X1 according to the source identification method of the present invention, since the identification agent is mixed with the adhesive paste for forming the core portion 1, some reason for return may occur during use. However, since the core part 1 remains unless it is completely used, it is possible to identify the origin of the toilet roll even if it is in use.

  Here, in the toilet roll X1 according to the source identifying method of the present invention, the number of layers (ply number) and the composition of the toilet paper base paper 2 to be configured are based on conventionally known techniques. For example, from what is called single-layered so-called single, it can be about double-layered double or triple-layered triple.

  However, when the number of plies increases excessively, adhesive paste such as water adhering to the core shaft is excessively absorbed, and the liquid existing between the core shaft 30 and the toilet paper base paper 2 is reduced, and an effective shaft is obtained. There is an increased risk that the pulling operation will not be performed.

  Further, the composition of the toilet paper base paper 2 is not particularly limited, and a papermaking raw material mainly composed of raw pulp is a known papermaking equipment and a papermaking process, specifically, a wire part, a press part, a dryer part, a size press, It can be manufactured through a calendar part or the like.

  Of course, when making paper, appropriate chemicals such as pH adjusters such as dispersants, caustic soda, and aqueous ammonia, antifoaming agents, preservatives, mold release agents, water-proofing agents, flow modifiers, and yield improvers are added. can do.

On the other hand, the value of the basis weight of the continuous sanitary thin paper according to the present invention is 12.5 to 25.0 g / m ² in the method for measuring the basis weight of JIS P 8124. (In addition, in the case of a laminated structure, the rice tsubo here is one per sheet constituting the layer.) When the range is exceeded, the sticking to the shaft deteriorates.
