Description

[Detailed description of the invention] This invention is a heat-resistant material that prevents the Noshi tiles from tipping over or sticking together even when the Noshi tiles are loaded on a trolley and the trolley is moved when firing the Noshi tiles. Regarding the holder.

Conventionally, when firing flat objects such as roof tiles, a tunnel furnace was used to place refractory bricks called shelves on a cart at several rows apart in the longitudinal direction, and as much material as possible to be fired was placed on one cart. It is common to pile up.

Furthermore, in order to minimize distortion at high temperatures, a method of baking in an upright position is also used.

Then, a clay strip called 1 string ± 1 is spread on the shelf board, and tiles are embedded in it to make it stand upright.

In particular, in the case of Noshi tiles, one string ±1 was attached to the top of the tile to prevent the Noshi tiles from falling over, but since the one string tile used to prevent it from falling is made of clay, it is not stable enough. During high-temperature firing, the tiles may become tilted due to shrinkage and cracks, and tiles may fall due to vibrations and shocks when the trolley is moved, resulting in a decrease in yield due to breakage, as well as depletion of clay resources and the production of defective products. This was a problem due to the pollution caused by mass disposal.

Recently, attempts have been made to make round holes in the shelf board and use pins made of ceramic or heat-resistant steel, and to place holding frames on the shelf board. In some cases, these methods are extremely difficult to work with, and
The automatic loading device also requires a complicated mechanism.

In this way, it was extremely difficult to advance automation in particular.

In order to solve these problems, the present invention has developed a comb tooth for firing tiles that prevents the tiles from sticking and falling by fitting spacer comb teeth made of heat-resistant material into the upper center of the tiles. This is what we provide.

The present invention will be explained below with reference to Examples.

Fig. 1 is a front view of the spacer comb teeth for firing Noshi tiles of the present invention, and 1 is a horizontal plate with comb teeth-like protrusions (hereinafter simply referred to as comb teeth) that are almost perpendicular on one side and inclined on the other side. A plurality of spacer comb teeth a are provided.

FIG. 2A shows the shape of the present invention which has been put to practical use, and FIG. 2B is a front view and a side view of the spacer comb teeth used for firing Warinoshi roof tiles.

The shape of the tip of the protrusion can be selected arbitrarily and is not limited to the shape shown in the figure.

FIG. 3A shows a side view of the spacer comb teeth for the Noshi tile fitted into the upper center of the tile.

FIG. 3B is a sectional view taken along a vertical plane passing through the center of the spacer comb teeth, and FIG. 3C is a plan view.

In FIGS. 1 to 3, a is a spacer comb tooth for a slotted tile, b is a slotted tile, C is a skid rail, and d is a shelf brick.

As shown in Figure 3B, a skid rail C is laid on the shelf board d, and Noshi tiles are stacked on top of it, and Noshi tiles are fired to keep the distance between the Noshi tiles constant and to prevent them from falling over. Set the spacer comb teeth a as shown in Figure 3.

As shown in Fig. 3B, the spacer comb tooth a of the present invention has a vertical surface facing the outside of the curve of the tile, and an inclined surface facing the upper end surface of the tile. The comb teeth are inserted between the noshi tiles so that they are in contact with the edges of the curves.

By inserting and placing the Noshi tile in this way, the spacer comb teeth and the Noshi tile will sandwich the tile from the left and right without creating a gap, as the spacer's own weight will lower the Noshi tile along the slope to compensate for the shrinkage of the tile due to baking shrinkage. It is possible to reliably maintain the space between the roof tiles under any temperature change conditions, and it is possible to prevent the roof tiles from falling in one direction.

That is, before, during, and after firing the tile, the horizontal plate of the spacer/the upper end of the tile must not come into contact with each other, leaving a gap between them.

Further, as shown in FIG. 2, a spacer is practically used in which the comb-teeth protrusions at both ends of the spacer are longer than those at the center to maintain the stability of the tile.

The purpose of C is to prevent the glaze from adhering to the bricks as it flows during the firing of the Noshi tiles.

As explained above, the present invention uses a spacer comb tooth made of heat-resistant material that hangs over the conventional one-string clay when firing Noshi tiles, thereby preventing the Noshi tiles, which are extremely unstable, from falling over, and when loading the tiles onto a trolley. can be automated, contributing to labor savings.

At the same time, compared to conventional work, it is effective in increasing yield and improving the shape of roof tiles.
