Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method and apparatus for producing soap tissue which is printed on sheets or in long rolls.

[Conventional technology]

Conventionally, paper soap is made by soaking relatively thin paper, for example paper slightly thicker than tissue paper, in a detergent solution, and in the case of bundles, it is soaked in the detergent solution for a long time because it is slow to penetrate into the inside. Then, at an appropriate time, they are pulled out of the detergent solution, separated one by one, and dried naturally or in a dryer. Another manufacturing method is to apply detergent to the paper with a brush, then dry it, and then wind it up on a winder if the paper is long.

[Problem that the invention seeks to solve]

However, such a manufacturing method has the following problems.

(11-It is inefficient to soak each sheet in detergent solution and is not suitable for mass production.

(2) When a bundle of paper is soaked in a detergent solution, it takes a considerable amount of time for the detergent solution to penetrate into the interior depending on the gamma degree of the detergent solution, and the process of making paper soap takes a very long time.

(3) Since the product is immersed in the detergent solution, the amount of detergent solution consumed varies and is not constant depending on the degree of penetration of the detergent solution.

(4) Processing is time consuming and the product inevitably becomes expensive.

The present invention was devised in view of the above-mentioned points, and its purpose is to create a product that can be mass-produced, uses reasonable detergent, and is inexpensive, as well as a single color, mixed color, color pattern, or trademark. To provide a method and apparatus for manufacturing soap tissue that can display a design, etc.

[Means for solving problems]

In other words, the means to achieve this purpose is to provide a detergent solution weighed to a predetermined concentration, and this detergent solution may be colorless or primary colored, and the detergent solution can be used for letterpress printing, gravure printing, offset printing, etc. A manufacturing method and apparatus for producing colorless or color printing on sheets or long webs of paper.

To explain this in more detail, let's take as an example a manufacturing method similar to gravure printing such as letterpress printing, gravure printing, and offset printing. The main part of the present invention corresponds to the printing part of these parts.

This printing section consists of a plate cylinder or cylindrical plate cylinder around which a sheet-shaped, for example, rubber plate is wrapped, an impression cylinder coated with rubber to perform printing by applying sufficient pressure, and a printing detergent liquid. A detergent liquid supply device that stores the detergent liquid in a tank, for example, for Dobuzuke, which supplies the detergent liquid to the plate;
It is equipped with a drying device that dries printed materials using electric heat, infrared lamps, etc.

When the detergent liquid is to be printed colorless, a colorless liquid weighed to a predetermined concentration is stored in the tank mentioned above, but when printing in primary colors, that is, single color or multicolor printing, A detergent solution of a color corresponding to the purpose is prepared. Of course, if the concentration or viscosity of the detergent solution increases due to evaporation of water, this point is detected by a detector, so that a constant amount of detergent solution is always stored. lzu4. if soso type, Boy 1; ÷ Shido J
1) 10 to 1 person [Operation] The operation will be explained in detail in the following Examples.

Hereinafter, one embodiment of the soap tissue of the present invention will be described in detail based on the drawings.

〔Example〕

Fig. 1 is an overall configuration diagram of an embodiment of the soap tissue of the present invention, Fig. 2 is an explanatory diagram of a plate cylinder in the printing section of Fig. 1, and Fig. 3 is an explanatory diagram showing another plate cylinder. be.

In FIG. 1, there is provided a detergent solution 1 weighed at a predetermined time, the detergent solution 1 is colorless or primary colored, and the detergent 't1
．． 1 is used to show the gravure printing method among printing methods such as letterpress printing, gravure printing, and off-cent printing, and colorless or monochrome printing is performed on the long rolled roll 2. .

That is, when the detergent liquid 1 is colorless or colored, for example, a non-la pigment is mixed as a desired coloring agent.

The detergent liquid 1 created in this manner is stored in a tank 3.

Further, the thickness of the paper 4 is determined depending on its intended use. In addition, a sheet-like plate or a cylindrical plate is used as the plate cylinder roll E for gravure printing, and in the case of the sheet plate 6.7 shown in Figs. 2 and 3, this is glued to the side of the plate cylinder roll. Attach with adhesive etc.

Since the sheet plate 6 is gravure printed, the sheet plate 6 has a plurality of recesses 6. is engraved. Further, the sheet plate 7 is a gravure plate on which a pattern is drawn.

In this way, the foregoing is prepared in advance before printing takes place. The manufacturing method for gravure printing using a detergent liquid is that the gravure 4 sent out from the paper roll 2 passes through a guide roll A1, a step roll B1, a vinyl roll C, etc.
It passes between the impression cylinder roll D and the plate cylinder roll E. The impression roll D is a hollow iron cylinder wrapped with rubber, but in the case of electrostatic gravure printing, a conductive roll is used. Of course, in this case, a conductive object is mixed into the detergent solution.

Also, a part of the plate cylinder roll E is immersed in the detergent liquid L, and when the paper 4 is printed and proceeds to the next drying process, the paper 4
A doctor 8 for removing detergent liquid is provided which lightly contacts the plate cylinder roll E to prevent excess detergent liquid from adhering to the plate cylinder roll E.

The angle of the blade edge of the doctor 8 is determined depending on the concentration of the detergent liquid 1, depending on the concentration of the detergent liquid 1. Also,
Although various types of Doctor 8 have been developed, their explanation will be omitted because they are not directly related to the present invention.

The plate 4 is pressed against the plate cylinder roll E side by the impression cylinder roll D, and the recess 6 of the plate cylinder roll E is pressed. The detergent liquid 1 adhering to the paper 4 is transferred to the paper 4.

Thereafter, the printed paper 4', that is, the soap tissue, passes through a guy roll F and the like and enters a drying section G surrounded by a dotted line. This drying section G is equipped with electric heating or infrared lamps, etc., and after drying and cooling, the next process is carried out, for example, by cutting to a predetermined length, folding it, and storing it in a predetermined case like tissue paper. Ru. In addition, in some cases, in FIG. 4, for example, in a manufacturing method and apparatus for two-color printing, the gill 4' that has completed monochrome printing passes through a drying section G, guide rolls, etc. in order to print the next color. Next, the printed paper 4'' is guided between the plate cylinder roll E and the impression cylinder roll 0, which are immersed in the colored detergent liquid 5, and is sent to the drying section G via the guide roll F etc. Soap tissue is produced through the steps explained in FIG.

Next, these effects will be explained.

First, a printing method for monochrome or colorless printing will be explained based on FIGS. 1 to 3.

The plate cylinder roll E to be prepared has been described above, so a description thereof will be omitted here. detergent? f1. Adjustment of l is made using the recess 6 carved on the edge of the 1st plate cylinder roll. Determined by depth, width, etc. At this time, if the viscosity of the detergent liquid 1 is mixed with, for example, an inorganic pigment for color printing, the viscosity of the detergent liquid 1 will naturally change, and the detergent liquid 1 will not enter the recess 61 and air bubbles will form at the bottom of the recess 61. .

In order to solve this problem, a surfactant, such as a sodium salt of a higher fatty acid, is added to the detergent liquid 1 to create a detergent liquid 1 with appropriate activity. Since it is a problem for this activity to change during the production of soap tissue, in order to keep it constant, it is measured by a sensor (not shown), and if the viscosity increases due to evaporation of water, it is measured by a sensor (not shown). Then, the amount of water corresponding to the measured value is supplied to the tank 3. Of course, tank 3 is equipped with a means for agitation, but depending on the situation, another tank may be prepared separately from tank 3 to mix the detergent. f1. There is also a method of adjusting l here and supplying it to the tank 3 with a pump.

The thus prepared detergent 1 is applied to the concave portion 6 of the plate cylinder roll E. When the paper 4 passes through this area, it is transferred to the paper 4, and a pattern as shown in FIG. 2 or 3 is printed.

Next, for example, in the case of two-color printing shown in Fig. 4, the preparation of detergent liquids 1 and 5 is the same as described above, but the paper 4' printed in color with detergent liquid 1 is used in the next step. It is necessary to dry it before printing, and after this step, color printing using the next detergent liquid 5 is performed.

Thereafter, as described above, it passes through the drying section G and is wound up, for example, by a winding machine.

Here, although gravure printing has been explained in this example, letterpress printing, electrostatic gravure printing, etc. are difficult and time-consuming to produce a sheet of soap tissue, or are not suitable for mass production. However, by using the manufacturing method and equipment using the printing technology of the present invention, the drawbacks of conventional products can be eliminated, and not only can products be made at low cost, but also have an aesthetic sense. You can make colored soap tissues.

Therefore, the soap tissue of the present invention, including the device,
This is an extremely useful method in practice.
