BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment (corresponding to claim 1 of the claims) of a method for manufacturing a fired product according to the present invention will be described with reference to FIGS. In addition, this first
In the examples, manufacturing of pottery as a fired product will be described as an example.

In FIG. 1 and FIG. 2, a reference numeral 10 is a sheet material made of a material (eg, paper) that is burned down by heating, and the printing original plate 11 is superposed on the upper surface of the sheet material 10. It is supposed to be done. This printing original plate 11 is a thin plate material having a thickness of several 100 μm, and a groove-shaped ink permeation part 13 in the shape of a convex part 12 (described later) to be formed on the surface of the sheet material 10 has a thickness direction. Has been penetrated by. The printing original plate 11 is (1) a printing original plate 11 formed by dispersing and fixing ferromagnetic powder in a binder, or (2) printing in which the ink permeation portion 13 is formed on a thin plate made of a ferromagnetic material. The original 11 and the like can be used.

(1) As the ferromagnetic powder dispersed and fixed in the binder, a mesh screen woven with synthetic fibers such as nylon or polyester, or fine metal wires such as stainless is used to form a printing pattern. It is possible to use a material in which a resin layer containing ferromagnetic powder is formed in a portion other than the ink permeation portion 13 and the like. In this case, as a method for forming the resin layer, a well-known photoresist to which ferromagnetic powder is added is applied to the screen, and the screen is exposed to an inverted shape of a printing pattern, and then an unnecessary portion is removed. A method of forming the ink permeation portion 13 by using the above method is preferable.
Ferromagnetic materials include iron, cobalt, nickel or their alloys, oxide-based magnetic materials, compound-based magnetic materials, etc.
Any conventionally known ferromagnetic material can be used. In addition,
If a sufficient tensile strength can be obtained only by the resin layer, the mesh original screen may be omitted and the printing original plate 11 may be formed only by the resin (including a so-called rubber magnet and plastic magnet) to which metal powder is added. In that case, the printing original plate 11 is etched or machined to form an opening portion (ink permeation portion) forming a printing pattern.
Further, the mesh screen may be formed of a ferromagnetic material.

(2) Ink penetrating part 13 on a thin ferromagnetic metal plate
For forming the ink, a thin plate of a ferromagnetic metal such as soft iron, cobalt alloy, nickel alloy or the like may be punched and processed by a method such as laser processing or etching to form the ink penetrating portion 13 forming a print pattern. .
A metal mesh plate on which the ink permeation part 13 is formed may be used by adhering a reinforcing mesh screen.

Then, by using the printing original plate 11 as described above and imprinting the ink 14 on the printing original plate 11, the convex portions 12 having the same shape as the ink penetrating portion 13 are formed on the sheet material 10. The sheet material 10 is printed with the ink 14, and then the sheet material 10 is used to make the baked product 1 of the present invention.
00 is manufactured (details will be described later). As a component of the ink 14, for example, a mixture of glass powder that is integrated with a fired product body 20 (described later) by firing and an adhesive that is a binder is used. Also,
As the glass powder contained in the ink 14, one containing a coloring material may be used.

The method for manufacturing the fired product 100 of the present invention will be described in detail below. << Printing Plate Positioning Step >> First, as shown in FIG.
The printing original plate 11 is superposed on the surface of the sheet material 10, and the printing original plate 11 is adsorbed by the magnetic force of the electromagnet 15 from the back side of the sheet material to be brought into close contact with the surface of the sheet material 10. At this time, in the electromagnet 15, the attracting force of the printing original plate 11 is controlled by adjusting the current in a current supply unit (not shown).

<< Printing Step >> Next, as shown in FIG. 2, the ink 14 is applied to the front side of the squeegee 16 provided on the upper surface of the printing original plate 11 so as to be frictionally slidable in the initial moving direction (the arrow direction in the drawing). The ink 14 is supplied and the ink 14 is rubbed against the printing original plate 11 by moving the squeegee 16, and the sheet material 10 is printed through the ink permeation portion 13. In the rubbing of the ink 14, the squeegee 16 is rubbed and slid on the upper surface of the printing original plate 11 to make one reciprocation, so that the ink 14 is pressed against the surface of the sheet material 10 in the ink permeation portion 13. In this step, the attraction force of the electromagnet 15 causes the entire surface of the printing original plate 11 to be in pressure contact with the surface of the sheet material 10 to prevent the formation of gaps and the like, and a sufficient frictional force is generated in the surface direction, so that the squeegee 16 is used as the printing original plate. Even when reciprocating while rubbing the surface of the printing plate 11, it is possible to effectively prevent the displacement of the printing original plate 11 and improve the accuracy. And
After the ink 14 is printed on the sheet material 10 as described above, the energization of the electromagnet 15 is released, the printing original plate 11 is separated from the sheet material 10, and the ink 14 on the sheet material 10 is solidified. In addition, the ink 14 at this time

Further, the demagnetization of the electromagnet 15 is carried out by the electromagnet 1
It is also possible to replace 5 with distance from the sheet material 10. As a method of separating the printing original plate 11 from the sheet material 10,
It is suitable to attract the printing original plate 11 from its back surface by magnetic force. According to this method, the suction force acts over a wide range of the printing original plate 11, and the printing original plate 11 can be stably detached without causing distortion or the like. Further, in this detaching work, the printing original plate 11 is placed on the convex portion 12
Since it can move accurately along the height direction of
It does not affect the shape of the convex portion 12. Further, the printing original plate 11 separated from the sheet material 10 is used for printing again after the sheet material 10 is replaced with a new one.
It is also possible to attract the printing plate 11 with a permanent magnet instead of the electromagnet 15. In this case, the attraction force of the printing original plate 11 is adjusted by moving the permanent magnet toward and away from the sheet material 10.

<< Baking Step >> Next, a pottery 20 is prepared as a main body of the fired product, and as shown in FIG.

The firing at this time is set to a temperature at which the binder in the sheet material 10 and the ink 14 is decomposed and vaporized, and the glass component in the ink 14 is melted and integrated with the pottery 20. Further, due to the firing at this time, gas is generated from the sheet material 10 and the ink 14, which may partially form a hole in the convex portion 12 formed by the glass component of the ink 14, In order to prevent such problems,
For example, it is advisable to moderate the temperature rise during firing, or to make the components of the ink 14 and the sheet material 10 contain protein that produces a small amount of carbon dioxide.

As described in detail above, according to the manufacturing method of the baked product 100 shown in this embodiment, the ink permeation portion 1
The printing plate 11 formed as 3 is used as the sheet material 10
