BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sagger used for firing flat tiles or large tiles.

[0002]

2. Description of the Related Art Japanese roof tiles, particularly curved ones such as gang tiles, are easy to stand on their own. Therefore, they are arranged vertically on a shelf bar without using a support tool, or the upper portion is pinched by a pin hanging down from the upper shelf bar. Although it was fired so that it did not fall over, the thing close to a flat plate like a Western tile was not only difficult to stand on its own, but also had a problem that it was easy to bend when baked vertically.

[0003] For this reason, there are drawbacks such as placing tiles horizontally in an H-shaped sagger and stacking the saggers for firing, or depending on the properties of the glaze of the tiles, the color tone will be different unless the stake is baked upright. In order to generate the slag, it was fired in a state where it was slightly inclined with respect to the vertical by using a sagger or a jig having another shape.

[0004]

A problem to be solved by the present invention is to provide a sagger that has both functions of standing grilling and flat grilling.

[0005]

According to the present invention, as a means for solving the above-mentioned problems , both ends of a long side and a short side are parallel .
A pair of left and right elongated side plates with escape grooves formed on both end surfaces of the long side, a main plate arranged between the side plates in a direction inclined in the length direction of the side plate, and the main plate at the upper and lower ends of the main plate water
A hook portion protruding only on the side forming an obtuse angle with respect to the flat direction is formed of a refractory.

[0006]

The present invention has the above-described structure, and has both functions of flat grilling and vertical grilling since both end surfaces of the side plates are parallel to each other.

In the case of flat baking, the saggers can be stacked by lowering the long side of the side plate, and the flat ceramic body such as a tile is placed on the main plate so as not to overlap with the hanging portion. It can be maintained in a horizontal state with a slight inclination.

[0008] In the case of baking, if the short side of the side plate is set downward, the saggers themselves can be erected and arranged side by side. By leaning on the main plate, the base can be held in a slightly inclined state in an upright state.

[0009] When saggers are packed and taken out in the case of baking, the saggers are stacked horizontally, and an automatic sagger filling machine and an automatic sagger picking machine using a suction cup are used. It can be used to improve work efficiency, and when it is put in a kiln, it can be knocked down and arranged on a shelf bar.

The product is inclined at an angle of 80 to 85 ° for a small deformation product generated during firing and 65 to 75 ° for a large deformation product. Both end surfaces of the main plate 3 are flush with both end surfaces 2a, 2a of the short side of the side plate 2, respectively.

Each side plate 2 has a pair of front and rear escape grooves 5 and 5 formed by cutting out both front and rear edges of an intermediate portion excluding both end portions of its long side along the plate surfaces 3a and 3b of the main plate 3.
Are formed.

The two hooks 4a and 4b are connected to the ends of the plate surfaces 3a and 3b of the main plate 3 having a large contact angle at the contact point (intersection) between the end of the main plate 3 and the short side end surfaces 2a and 2a of the side plate 2. It is formed so as to protrude along the edge.

Further, at both ends of the main plate 3, Ken b projecting from a tile body a fired using the sagger 1 of the present embodiment is provided.
The sagger 1 according to the present embodiment having the above-described configuration in which the opening 6 for fitting therein is formed, has an end surface 2 a of the short side of the side plate 2,
Regardless of which surface of 2a is set as the bottom surface, the plate surface 3 of the main plate 3
The inclination angles of a and 3b, the positions of the hooks 4a and 4b, and the like are the same, so that they can be used in either upward or downward direction. Further, the same result can be obtained by flattening any of the end surfaces 2b, 2b of the long sides of the side plate 2 as a bottom surface.

When the sagger 1 is fired in a flat state using the sagger 1 of the present embodiment, the sagger 1 is set so that both end surfaces 2b and 2b of the long side of the side plate 2 are horizontal. The slab is placed on the basement d in a posture lying flat, and the tile substrate a is placed on the plate surface 3a of the sagger 1 facing upward. At this time, the plate surface 3a
In the opening 6 near the hook 4a
Is fitted.

As a result, the tile backing a is
In this state, the sagger 1 holding the tiled material a in such a state that the sagger 1 is held in close contact with the plate surface 3a is attached to the side plates 2, 2 and the long side end surfaces 2b, 2b. Raise multiple volumes so that they abut each other.

When the sagger 1 is fired using the sagger 1 according to the present embodiment with the tiles a standing upright, the sagger 1 is placed such that both end surfaces 2a, 2a of the short side of the side plate 2 are horizontal. The main body 3 of the sagger 1 is placed on the shelf bar c so that the tile plate a leans on the front plate surface 3a slightly upward and the lower end of the front plate surface 3a. The lower edge of the tile substrate a is placed on the hook 4a and locked. At this time, the ken b of the tile body a is fitted into the opening 6.
