However, the present invention is not limited to the following embodiments, and various design changes can be made without departing from the matters described in the claims. In addition, in the process of commercializing the web sent from the raw fabric, the devices used other than the process of spraying the drug onto the web (that is, the spraying apparatus for spraying the drug onto the web) are known ones that are generally used It becomes possible in.

  In addition, embodiment described below is an example which installed the spraying apparatus which sprays a chemical | medical agent on the web which concerns on this invention in the manufacturing line which manufactures the toilet paper containing a moisturizing component as a product.

  As shown in FIGS. 1 and 2, the spray device for spraying a medicine onto the web according to the present embodiment (hereinafter simply referred to as “spray device”) has a web 2 fed from a raw roll (not shown). Used in the process of being manufactured as toilet paper containing moisturizing ingredients (not shown).

  The configuration is such that a spray chamber 1 in which only the entrance / exit 11 of the web 2 communicates with the outside is provided, and the moisturizing agent 3 as a desired medicine is supplied into the web 2 fed from the entrance / exit 11 of the spray chamber 1 in the spray chamber 1. In addition to the first sprayer 12, a second sprayer 13 for spraying the moisturizing agent 3 onto the web 2 fed from the inlet / outlet 11 of the spray chamber 1 is provided. In the spray chamber 1, it is preferable that the first sprayer 12 be installed on the upstream side of the web 2 that is fed in relative to the sprayer 13 (see FIG. 1).

  The spray chamber 1 is provided with a lower surface opening 14 on the bottom surface and an upper surface opening 15 on the ceiling surface. In addition, as shown in FIG. 2, the entrance / exit 11 of the web 2 provided in the spray chamber 1 has a flat rectangular shape and two locations on the side of the spray chamber 1, and the level from the floor of the production line is horizontal. Has been.

  Further, the spraying apparatus is installed so that the piping 4 having the lower surface opening 14 of the spraying chamber 1 as an inlet and the upper surface opening 15 of the ceiling surface as an outlet surrounds the spraying chamber 1. This pipe 4 collects the surplus humectant 3 that has not adhered to the web out of the humectant 3 sprayed from the first sprayer 12 and the second sprayer 13 by providing a vacuum means to the second sprayer 13. It becomes a passage to send. 1 and 2, the second sprayer 13 is disposed inside the outlet portion of the pipe 4.

  As an example of the vacuum means, a vacuum pump 5 as shown in FIGS. 1 and 2 can be cited. Further, in the present invention, including the case where the vacuum pump 5 is installed at a position as shown in FIG. 1 and FIG. 2, the moisturizing agent 3 collected in the pipe 4 together with the vacuum pump 5 is against gravity, that is, the first It is preferable to install a blower 6 that can be sent together with air to the side where the two sprayers 13 are located.

  In addition, each of the first sprayer 12 and the second sprayer 13 has, for example, an intermittent timer (not shown) having a circuit as an intermittent spray mechanism so as to spray the moisturizing agent 3 at regular intervals. Is provided. Further, the spray device is provided with, for example, a microcomputer (not shown) as a control means for controlling the spray amount of the first sprayer 12 and the second sprayer 13.

  Hereinafter, a process (spraying method) of spraying a medicine onto a web performed in a spraying apparatus will be schematically described with reference to FIGS. 1 and 2. In the following, the entrance / exit 11 of the web 2 of the spray chamber 1 will be described separately from the entrance 111 and the exit 112 for convenience.

  First, the web 2 for manufacturing toilet paper from the raw fabric roll is sent out toward the spraying device. Further, the web 2 is fed into the spray chamber 1 from the inlet 111 of the spray chamber 1 of the spray device. Note that the vacuum pump 5 and the blower 6 may be operated from this point.

Next, when the web 2 is sent to just below the first sprayer 12, the moisturizing agent 3 is sprayed from the first sprayer 12 to the web 2 intermittently at regular intervals by an intermittent timer (first spraying step). After this time, the first sprayer 12 continues to spray onto the web 2 intermittently at regular intervals. The spray amount of the humectant 3 of the first sprayer 12 on the web 2 is, for example, 0.3 to 25 g / m ² , the spray speed is, for example, 10 to 30 m / second, and the number of sprays per unit time is What is necessary is just to adjust suitably, considering the said spraying amount. However, as will be described below, the spray amount of the first sprayer 12 is reduced with the passage of time by the microcomputer.

The spray amount of humectant 3 was 0.3~25g / m ^2, the degree of moisturizing effect appears lower limit of about 0.3 g / m ² becomes as a product, by humectant 3 in the production line the web 2 is not cut This is because the upper limit of is about 25 g / m ² . The number of sprays per unit time may be appropriately adjusted based on this numerical value in consideration of the spray amount per one time of the first sprayer 12.

  The spray rate can be determined by the nature of the drug, for example, the viscosity of the humectant 3. In addition, it is preferable that the spray amount and the spray speed are appropriately adjusted according to the type of the medicine to be sprayed.

  Of the moisturizing agent 3 sprayed from the first sprayer 12, the surplus that did not adhere to the web 2 accumulates on the bottom surface of the spray chamber 1, but the lower surface of the spray chamber 1 because the vacuum pump 5 is operating. It is drawn from the opening 14 to the inlet of the pipe 4. Furthermore, the surplus moisturizing agent 3 is conveyed by the vacuum pump 5 and the blower 6 to the second sprayer 13 disposed inside the outlet portion of the pipe 4 (reuse process).

  Then, the excess moisturizing agent 3 conveyed to the second sprayer 13 is intermittently sprayed from the upper surface opening 15 of the spray chamber 1 to the web 2 sent to just below the second sprayer 13 at a constant interval. (Second spraying step). The spray amount and spray speed of the moisturizing agent 3 of the second sprayer 13 on the web 2 may be the same as those of the first sprayer 12, and the number of sprays per unit time may be the same. However, as will be described below, the spray amount of the second sprayer 13 increases with time by the microcomputer.

  As for the moisturizing agent 3 sprayed from the second sprayer 13, the surplus that did not adhere to the web 2 accumulates on the bottom surface of the spray chamber 1, but the lower surface of the spray chamber 1 because the vacuum pump 5 is operating. It is drawn from the opening 14 to the inlet of the pipe 4. Furthermore, the surplus moisturizing agent 3 is transported by the vacuum pump 5 and the blower 6 to the second sprayer 13 disposed inside the outlet portion of the pipe 4 (reuse process) and used in the second spray process. become.

  The web 2 sprayed with the humectant 3 and fed out from the outlet 112 of the spray chamber 1 is then subjected to the remaining process of the production line, for example, a process of stacking two sheets. After being finally wound on a roll, the toilet paper containing a moisturizing component is commercialized by being divided into an appropriate size in the width direction.

Here, the relationship of the spray amount which changes with time in the first sprayer 12 and the second sprayer 13 is such that the spray amount of the moisturizing agent 3 is 0.3 to 25 g / m ² by a microcomputer provided in the spray device. In the range, the total amount of spray per unit time is constant, the spray amount of the first sprayer 12 is gradually reduced, and the spray amount of the second sprayer 13 is gradually increased. For example, the spray amount of the first sprayer 12 and the second sprayer 13 as shown in FIG.

  In FIG. 3, the vertical axis is the spray amount (q), the horizontal axis is the time (t), the spray amount a of the first sprayer 12, the spray amount b of the first sprayer 13, and the total amount w of spray over time. Respectively.

  Then, in the spraying device for the medicine on the web according to the present embodiment, the humectant 3 is sprayed on the web 2 in the spray chamber 1 by the step of spraying the medicine on the web (spraying method). The floor surface around the production line is not wetted by the moisturizing agent 3. Further, since the surplus humectant 3 that has not adhered to the web 2 is collected and sent to the second sprayer 13 through the pipe 4, the second sprayer 13 sprays the web 2 again to perform reuse. The humectant 3 can be effectively used without waste. Furthermore, since the moisturizer 3 is intermittently sprayed from the first sprayer 12 and the second sprayer 13 by an intermittent timer and the spray amount is controlled by the microcomputer, the moisturizer 3 to be sprayed per unit time The amount per unit area can be adjusted, and spraying according to the type of moisturizing agent 3 to be sprayed becomes possible.

  Therefore, in the present invention, various products including toilet paper containing a moisturizing component can be manufactured with high yield and high productivity, and the floor surface of the production line is not wetted by the drug, and the sprayed drug is effectively used without waste. It is possible to provide a spraying apparatus for spraying a drug onto a web and a spraying method for spraying a drug onto the web, which can be used and the amount per unit area of the sprayed drug and the number of times per spraying time can be adjusted. .

  Here, in the said embodiment, the spraying apparatus which sprays a chemical | medical agent on the web which concerns on this invention is the manufacturing line in which the toilet paper containing a moisturizing component is commercialized, Description that it is used before the process of stacking two sheets of webs. However, it can also be used after passing through a process of stacking two webs. In addition, for example, when spraying a small amount of medicine for reasons such as spraying every few meters, it is only necessary to set an intermittent timer, and the intermittent timer and microcomputer are examples, Other appropriate intermittent spray mechanisms and control means can be employed. In addition, if a vacuum pump is installed at a position higher than that of the second sprayer, it is possible to omit means such as a blower using the weight.

  As mentioned above, although embodiment of this invention was illustrated and explained in full detail, this invention is not limited to the said embodiment. For example, the medicine to be sprayed includes moisturizers, pastes, softeners, disinfectants, detergents, pharmaceutical ingredients, pigments, fragrances, fragrances and the like.
