Description

  The present invention relates to a method for producing roll paper products such as toilet paper and kitchen towels. More specifically, the present invention relates to a method for producing a rolled paper product having functions such as fragrance, deodorant property, and antibacterial property.

  Conventionally, a means of placing a liquid or solid fragrance or deodorant in the kitchen or toilet for the purpose of fragrance or deodorant has been taken, but it is necessary to replenish the fragrance or deodorant, which is troublesome. It was work. In addition, there has been a problem that the fragrance and deodorant containers become garbage that is difficult to regenerate after use. Thus, in recent years, roll paper products have been provided in which functions such as fragrance and deodorization are imparted to products by adding fragrances or deodorants to toilet paper and kitchen towels.

As an example of a method for producing such a roll-shaped paper product, a method of applying an aromatic microcapsule to the inner surface of a paper tube of toilet paper (Patent Document 1), a method of applying paradichlorobenzene to the inner side of the paper tube (Patent Document 2) or a paper tube such as a method (Patent Document 3) in which a liquid fragrance is sprayed from both sides of a paper tube inside the paper tube in a step prior to the step of winding the paper around the paper tube. A method of applying a functional chemical to the inside of the inside has been proposed. Further, in the process before the process of winding the paper around the paper tube, a method of applying a liquid fragrance to the outside of the paper tube (Patent Document 4), or the outside of the paper tube for winding the paper around the paper tube. There is also known a method of applying a functional chemical to the outside of a paper tube, such as a method of blending a fragrance with a paste to be applied to a paper (Patent Document 5). There is also a method in which a fragrance is blended in the glue in the step of gluing the end of the roll paper product (that is, the part where the product starts to be used). Furthermore, there is also known a method in which a perfume is attached to the inner surface of a paper tube after the reel part has completed winding, and then cut into toilet paper dimensions (Patent Document 6).

  However, in the case of the said patent documents 1 and 2, in order to apply | coat a fragrance | flavor in the state of the base paper before forming a paper tube, and to process into a paper tube after that, the manufacturing process of a roll-shaped paper product after application | coating of a fragrance | flavor It takes a long time to be introduced into the air, and the fragrance is volatilized during that time. Furthermore, the inner surface of the paper tube receives a strong frictional force from the core rod (mandrel) that supports the roll product in the paper winding process. Aromatic volatilization also occurs. In the case of Patent Document 3, since the fragrance is sprayed from both sides of the long paper tube before cutting, the amount of fragrance applied is not uniform and the fragrance of the product varies. .

  Moreover, in the case of the said patent document 4, since the toilet paper is apply | coated to the outer side of a paper tube and the toilet paper is wound on it, fragrance is weak, and it is fragrance in the initial stage and the end of use of a product. In addition, the fragrance is transferred to the glue applied to the outside of the paper tube for winding the paper around the paper tube, and the workability of the cleaning operation when changing the product type is also deteriorated. Moreover, in the case of the said patent document 5, since a fragrance | flavor material is mix | blended with the glue apply | coated to the outer side of a paper tube in order to wind up paper in a paper tube, the workability | operativity at the time of switching to the product which does not add a fragrance | flavor is good. There is a possibility that the sizing roll will deteriorate due to the fragrance. In the method of Patent Document 6, it is difficult to uniformly apply the fragrance to the entire inner surface of the paper tube, and the fragrance tends to be lost.

  Also, in the process of gluing the roll end of the roll paper product, the method of blending the fragrance with the glue will immediately use the fragrance application part immediately after the start of use of the product. Further, it has a problem that it cannot be maintained, and further, the fragrance affects the discoloration and drying properties of the paste, thereby reducing the effect of gluing. Further, sometimes, the printed pattern applied to the inner surface of the film packaging bag is peeled off by the influence of the fragrance when it comes into contact with the product, thereby deteriorating the image of the product.

  The present invention overcomes the problems of the conventional method for producing a roll-shaped paper product with added functionality, and eliminates the loss of functions such as fragrance within the manufacturing process, thereby prolonging the function added to the product. The present invention provides a method for producing a rolled paper product that can last for a long time, prevents deterioration of equipment in the production process, and does not deteriorate product quality.

  (3) The method for producing a roll-shaped paper product according to (1) or (2), wherein the liquid coating apparatus has a coating gun for spraying and coating a liquid.

  (4) In the roll paper product according to (3), the coating gun sprays and applies the coating liquid in a substantially linear path to the individual roll paper products being transported. Production method.

  (5) The liquid application device detects individual roll-shaped paper products sequentially conveyed by a product conveyance conveyor by a product detection sensor, sends a detection signal to a solenoid valve through a control panel, and according to a set program, By opening and closing the electromagnetic valve, the functional liquid is intermittently sent from the functional liquid container communicating with the application gun through the electromagnetic valve to the application gun, and the individual roll-shaped paper products detected by the product detection sensor By detecting the presence or absence of functional liquid jetting by the action of spraying functional liquid on the inside of the roll in a fixed amount and the functional liquid application confirmation sensor installed between the coating gun and the roll paper product, An apparatus for performing an operation of sending a detection signal to the control panel to stop the product conveyance conveyor and / or an operation of issuing an alarm when it is detected that the functional liquid is not ejected Rolled paper product manufacturing method according to feature that (1) to (4) any one of clauses that there.

  (6) The functional liquid is a liquid containing at least one selected from a fragrance, a deodorant, and an antibacterial agent, according to any one of (1) to (5), The manufacturing method of roll-shaped paper products of description.

  According to the method for producing a roll-shaped paper product of the present invention, after cutting a long roll-shaped paper into a roll-shaped paper product having a final product size, the inside of the rolls of the individual roll-shaped paper products cut, that is, Since it can be manufactured by spraying functional chemicals on the inner surface of a paper tube or the like for winding paper, the function imparted by liquid application does not evaporate or disappear during the manufacturing process. Compared with the conventional manufacturing method, there is no variation among individual roll-shaped paper products with a small amount of chemicals used, and functions such as stable fragrance can be imparted. Moreover, the obtained individual roll-shaped paper products can maintain a stable function until the end of use regardless of the usage form of the product. Furthermore, since the functional liquid does not adhere to the packaging bag of the product, the printing ink of the packaging bag is not peeled off, and the product image is not deteriorated.

  In addition, since liquid does not transfer to other equipment during the manufacturing process, rolls and conveyors of manufacturing equipment are not deteriorated, and when switching product types, switching is performed simply by stopping spraying with a coating gun. Therefore, workability is also improved. Furthermore, since the manufacturing method of the present invention can apply the functional liquid on-line by the application gun method, the application amount can be uniformly controlled, and the application status is also equipped with a sensor. Therefore, it is possible to monitor abnormalities such as defective coating, and quality control is facilitated.

  Hereinafter, although the manufacturing method of this invention is demonstrated in detail taking the manufacturing method of the toilet paper which provided the fragrance as an example, of course, this invention is not limited at all by this.

  FIG. 1 is a schematic diagram showing a flow of a manufacturing process of the toilet paper of the present invention. In FIG. 1, a paper web 2 is wound up in a rewinding step 1 on a long paper tube (not shown) sent from the paper tube manufacturing step, and the length is about 114 mm and a length of 2 to 3 m. A roll-shaped paper 3 is manufactured. The obtained long roll-shaped paper 3 is sent to the cutting process 5 through the adjustment process 4, cut into toilet paper (roll-shaped paper product) 6 having a predetermined width, and sent to the transport process 7. Next, the individual toilet paper 6 is scented by applying a fragrance to the inner side of the roll, that is, the inner surface of the paper tube, by the liquid application device 8 provided in the middle of the transporting process 7 during the sequential movement of the transporting process 7. After the property is imparted, the product is sent to the packaging process 9 for packaging, and sent to the product warehouse through the boxing process 10.

  FIG. 2 is a diagram illustrating the liquid coating apparatus 8 provided during the transport process illustrated in FIG. In FIG. 2, the liquid application device 8 basically includes a product conveyance conveyor 11, a product detection sensor 12, an application gun 13, and an application confirmation sensor 14. When the product detection sensor 12 detects the toilet paper 6 which has moved in the direction of the arrow X on the product conveyor 11, a signal is sent to the electromagnetic valve 16 through the control panel 15, and the compressed air electromagnetic valve is set according to the set program. 16 is opened and closed, and functional liquid is intermittently sent from the functional liquid container 17 connected to the electromagnetic valve 16 by the high pressure hose 19 to the application gun 13 connected to the electromagnetic valve 16 by the same high pressure hose. A perfume is sprayed and applied uniformly from the gun 13 to the inner surface of the roll of the toilet paper 6 in a certain amount. In this case, the application confirmation sensor 14 installed in front of the application gun 13 detects the passage of the fragrance sprayed from the application gun 13 and confirms that the fragrance has been reliably applied to the toilet paper 6. In the case where the passage of the fragrance is not detected, a signal is sent to the control panel 15 and an alarm is issued or / and the product transport conveyor 11 is stopped.

  In the present invention, as the coating gun 13 used in the liquid coating apparatus 8, a glue gun used for hot melt coating or the like can be used.

It is not something.

  Also, by controlling the nozzle diameter, spraying time, and compressed air of the application gun 13, the application amount can be controlled in units of 0.01 ml so that application can be performed 3 times / second or more. preferable. In this case, the nozzle diameter is preferably 0.25 to 1 mm, and the time for one injection is preferably 300 ms or less. If the nozzle diameter is less than 0.25 mm, the application amount of the functional liquid decreases, and there may be cases where sufficient functions cannot be imparted to the product, and if the nozzle diameter exceeds 1 mm, the application amount of the functional liquid This is not preferable because not only is the function of the product oversaturated, which is uneconomical but also adversely affected by excessively applied functional components. Further, if the time of one injection exceeds 300 ms, it becomes impossible to apply 3 times / second or more corresponding to the product flow, and the production efficiency is lowered. Moreover, the tank 17 into which the functional liquid is placed is a container whose pressure can be adjusted by the pressure adjusting valve 18, and preferably has a configuration in which the liquid in the tank can be easily replaced.
