Description

[Detailed description of the invention] The present invention relates to a method for glazing dry roof tiles.

Looking at the continuous manufacturing process for traditional Japanese tiles, we see that clay chips are put into a kneading machine, kneaded, and then extruded into a single strip-shaped Japanese tile base. They are cut to a certain length, press-molded into the desired shape of the Japanese tile base, stacked in multiple stages on the pallets of a drying cart, and transported to the drying room. After this, the drying cart is removed from the drying room. After going through a series of steps, such as pulling out, hanging one end of the dry tile called Shiroji on the hanging type of the required trolley conveyor, fully glazing it with glaze, loading it on the corresponding glazed tile complete firing trolley, and firing. , mass production and automation are being promoted.

In order to apply glaze to the dried tiles, the dried tiles are suspended on a rack of a trolley conveyor, and the glaze is conveyed from below to above the cascade of glaze that is falling like a waterfall. Then, the surface side of the dried tile is pushed into the flow of the glaze, and the glazed tile is lifted up and transported, similar to a dip coating, and the glazed tile is carried suspended over a long distance, making sure to remove any drippings of glaze. I deal with it by doing things. For this reason, it is customary to apply glaze not only to the entire surface of the tile, but also to the periphery of the back of the tile. Therefore, more glaze than necessary is always wasted, resulting in wastage of expensive glaze. However, after glazing, sufficient dripping must be done, which makes the transportation line needlessly redundant, making it difficult to further reduce the cost of Japanese tiles through mass production. On the other hand, as is well known, the roofing situation with Japanese tiles is as follows:
They are firmly stacked and installed one after the other from one side of the roof to the other, and the roof is finally installed.

The present invention was invented in view of the above-mentioned points.
Alternatively, by stacking the tiles horizontally and vertically and transporting them in series in a roofing-like state, glaze is uniformly spray-painted on the necessary parts of the tile surface in the roofing-like state, and the tiles are The reverse side is heated, and the part where the dried tiles overlap is completely unglazed to minimize waste of glaze.
Achieving efficient glazing processing, ＊I aim to fully reduce the conveyance line by drying the glazed tiles in a short time, ii) Eliminate unevenness in the firing after firing, and in turn - reduce and improve product costs. The aim is to improve quality by standardizing tile products.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
