（従来の技術）
従来上り広く行なわれている金型プレス成形法は、金型
キャビティ内に原料坏土粉末を充填し上 〜下パンチで
締め付けてタイルを成形している。(Prior Art) The mold press molding method that has been widely used in the past involves filling raw clay powder into a mold cavity and tightening it with upper and lower punches to form a tile.
この金型プレス成形方法では、通常、金型に多数のキャ
ビティを設けておき一回の圧縮工程で何枚ものタイル素
材を成形するが、金型の加圧面積が大きいため加圧時に
金型が清白変形し易（、特に薄手のタイルを成形する場
合、タイルの厚みを均一にすることが困難であった。In this mold press molding method, a large number of cavities are usually provided in the mold and many tiles are molded in one compression process, but since the pressurized area of the mold is large, the mold (especially when forming thin tiles, it was difficult to make the thickness of the tiles uniform).
また金型プレス成形方法の成形圧力は通常３０〜８０Ｋ
ｇ／ぐ一２程度であるが、この程度の成形圧力で圧縮成
形したタイル素材は緻密化が十分とはいえず成形体内に
空隙が生じ焼成時に変形することがありな。In addition, the molding pressure of the mold press molding method is usually 30 to 80K.
Although the tile material is compression-molded at this level of molding pressure, it is not sufficiently densified and voids are created within the molded product, which may cause deformation during firing.
さらに金型の表面が摩耗したり、逮料粉末が付着して成
形性を損なう心配があるほか、金型の置傘も短く、金型
表面の清掃や金型の取替作業に時間を要するなどの問題
点があった。Furthermore, there is a risk that the surface of the mold will wear out or that powder particles will adhere to it, impairing the moldability, and the length of the mold can also be short, making cleaning the mold surface and replacing the mold time-consuming. There were problems such as:
（発明の構成）
本発明は上記問題点に鑑み、緻密で薄手のタイルを量産

The gist is:
（作用）
上記構成によれば、原料粉末を２本の加圧ローラにより
圧延するため大きな成形圧力を加えることができ、薄手
で緻密なシート体を成形できる。(Function) According to the above configuration, since the raw material powder is rolled by two pressure rollers, a large molding pressure can be applied, and a thin and dense sheet body can be molded.

。According to the first embodiment, since the raw clay powder is rolled into the sheet body 8 using the rolling machine 1 equipped with the pressure rows 22 and 3, the forming pressure is extremely high and the sheet body 8 is
The tile material 10 punched out from the tile material 10 is extremely dense, and since the molding pressure is applied uniformly, the thickness remains constant even if it is thinned. By the way, according to the rolling machine 1 equipped with pressure rows 22 and 3, the rolling capacity is 500 Kg/am2 to 1000 K.
It is possible to easily obtain a molding pressure of about 100 g/am.

次に本発明の第２実施例を第４図に基プさ説明する。Next, a second embodiment of the present invention will be explained based on FIG. 4.

圧ロー２１３間に送り込まれ圧延される。FIG. 4 shows the rolling apparatus 11 used in the second embodiment, and shows the hopper 1 disposed above the pressure loaves 12 and 13.
The inside of 4 is divided into two chambers by a partition wall 15, one raw material chamber 16 is filled with, for example, pigment powder, and the other raw material chamber 17 is filled with clay powder. And each raw material room 16.
Appropriate amounts of the pigment powder and the clay powder are fed between the pressure row 212 and the pressure row 213 by a screw figurine (not shown) provided at 17 and rolled.

例と同様にして所要形状のタイル素材を打ち抜く。According to this rolling apparatus 11, a sheet body can be rolled and formed from a sheet body made of raw materials and a clay sheet, and at the same time, a pigment sheet body and a clay sheet body are pressed together to form a laminated sheet body. A tile material having a desired shape is punched out from this laminated sheet body in the same manner as in the first embodiment described above.
第５図に圧１１装ｆ１１１で圧延成形した積層シートか

面図を示す。FIG. 5 shows an enlarged cross-sectional view of a tile material formed by punching and forming a laminated sheet using a punching machine from a laminated sheet that has been rolled and formed using a pressure 11 (F111).
タイル素材１８は顔料層１つと坏土層２０を備えた積層
構造となっており、各層１９．２０とりわけ顔料層１８

制御してｒＩ４整する。The tile material 18 has a laminated structure including one pigment layer and a clay layer 20, each layer 19.20, especially the pigment layer 18.
The thickness of the pigment powder is adjusted by controlling the amount of pigment powder supplied using a screw feeder.
第２実施例に示すタイル成形方法は摩耗が不可避な床タ
イル等の成形に好適である。The tile forming method shown in the second embodiment is suitable for forming floor tiles, etc., which are subject to inevitable wear.
従来、タイルに色彩を施すには補薬を表面に掛けるか、
あるいは坏土に予め顔料を混入させる方法が採られてい
た。Traditionally, to add color to tiles, you either apply a reagent to the surface, or
Alternatively, a method was adopted in which pigments were mixed into the clay in advance.
タイルに補薬を施す場合、厚く塗布すると補薬がタイル
の端縁から垂れ下が９、タイルの外観形状を損なう、そ
のため補薬層の厚みには限界があり補薬を使用して床タ
イルに色彩をほどこしても摩耗により短期間で剥げ落ち
でしまう、また補薬屑と坏土層の収縮率の違いにより焼
成時、タイルが湾曲変形することがあった。When applying reagents to tiles, if applied thickly, the reagents will hang down from the edge of the tile, damaging the appearance and shape of the tile.Therefore, there is a limit to the thickness of the reagent layer, and floor tiles using replenishers may Even if colors were applied to the tiles, they would peel off in a short period of time due to abrasion, and due to the difference in shrinkage rates between the replenisher waste and the clay layer, the tiles would sometimes become curved and deformed during firing.
一方、顔料を使用して色彩を施す場合、タイルは内８ｓ
まで色彩を有しているので摩耗による影響はないが、そ
の反面、坏土全体に顔料を均一に混入しなければならず
多量の顔料を必要とした。On the other hand, when applying color using pigments, the tile is made within 8 seconds.
Since the clay is colored, it is not affected by wear, but on the other hand, the pigment must be mixed uniformly throughout the clay, requiring a large amount of pigment.
上記第２実施例によれば、タイル素材１８の表面に摩耗
に耐え得る適度の厚みを有する顔料層１９を形成でき、
しかも顔料層１８と坏土層２０は加圧ローラ１２，１３
による大きな成形圧力により緊密に圧着されるため顔料
層１８と坏土層１９の収縮率が異なるにもかかわらず、
焼成時に湾曲変形することはない。According to the second embodiment, the pigment layer 19 having an appropriate thickness that can withstand wear can be formed on the surface of the tile material 18,
Moreover, the pigment layer 18 and the clay layer 20 are formed by pressure rollers 12 and 13.
Although the shrinkage rates of the pigment layer 18 and the clay layer 19 are different because they are closely bonded by a large molding pressure,
It does not curve or deform during firing.
なお、第２実施例では２層からなる積層構造のタイル素
材１８成形する場合について述べたが、ホッパ１４の隔
壁１５の数を増やすことにより３層の積層シート体を成
形することも可能である。Although the second embodiment describes the case of molding the tile material 18 with a two-layered laminated structure, it is also possible to mold a three-layered laminated sheet body by increasing the number of partition walls 15 of the hopper 14. .
また単層のシート体を別々に成形しておき、そけをさら
に別の加圧ローラを用いて圧着させることにより多層に
することも可能である。It is also possible to make a multilayer sheet by separately molding a single-layer sheet and pressing the edges using another pressure roller.
例えば３層からなるタイル素材を成形し両側の層に同じ
原料粉末を用いると中間層との収縮率の違いによる湾曲
変形を確実に防止できる。For example, by molding a tile material consisting of three layers and using the same raw material powder for both layers, it is possible to reliably prevent curved deformation due to a difference in shrinkage rate with the middle layer.
また中間層に軽量材料を使用することによりタイル全体
の重量の軽減を図ることもで軽、高層建築物の外壁に貼
着するに適した軽量タイルを成形することも容易となる
。Furthermore, by using a lightweight material for the intermediate layer, the weight of the entire tile can be reduced, making it easy to form a lightweight tile suitable for being attached to the exterior wall of a high-rise building.

均一に加わるため厚みが一定となる。(Effects of the Invention) According to the present invention, a raw material powder is rolled by two pressure rows 2 to form a sheet body, and a tile material of a desired shape is punched from this sheet body to form a tile. The molding pressure makes it possible to mold dense tiles, and even when molding thin tiles, the molding pressure is applied evenly, so the thickness remains constant.

できるため焼成時の変形を防止できる。Furthermore, it is also possible to mold tiles with a laminated structure that has multiple layers made of different raw materials, such as pigment layers and clay layers, and even if the shrinkage rate of each layer is different, it can be molded precisely with high molding pressure, so it can be fired. It can prevent time deformation.
