Description

[Detailed Description of the Invention] The present invention relates to a dead firing jig that is housed in a tile firing furnace and used for firing tiles.

Conventionally, all types of tile firing furnaces have not been equipped with any fixed equipment to hold the tiles to be fired.
Loading and unloading the tiles into the furnace or onto the firing trolley was done by manually arranging the tiles to be fired one by one, which required a great deal of time and labor. A jig has been developed that uses shaped protrusions to arrange the tiles to be fired so that they do not come into contact with each other. There was a drawback that this occurred.

The present invention eliminates these drawbacks and provides a dead firing jig that has the effect of simplifying and speeding up loading and unloading of tiles to be fired and reducing the defective rate of products.The configuration is shown in the figure. To explain with an example, an underframe 1 in the shape of a square timber, which is more suitable than a refractory material for ceramics, has a rectangular groove 3 in the longitudinal direction recessed in the upper surface 2, and a plurality of holes 4 are formed at predetermined intervals in the rectangular groove 3. ,4...

A tile support rod 6 of an appropriate length whose upper part has a conical or truncated conical taper part 5 has a lower part connected to the hole 4.4 of the underframe 1.

The present invention is constructed by inserting and mounting ... in a freely insertable and removable manner.

Next, to explain the operation of the present invention with the configuration described above, the tile support rods 6, 6... and the tile support members 9, 9... are inserted on the hearth or cart. The underframes 1, 1 are placed side by side at an appropriate distance, and the opposing tile support rods 6, 6, 6.
・・・・・・Tiles to be fired A, A... are placed vertically in parallel so that the bottom surfaces of the tiles straddle the top ridgelines 7, 7 of the tile support material 9゜9. Even if the tile to be fired is tilted, it is regulated so that the tile does not touch the upper end of the tile support rods 6, 6, etc., or come into contact with adjacent tiles, and the high heat during firing is As shown in FIGS. 4 and 5, even if the jig and tiles to be fired undergo expansion and contraction changes, the tile support will move by a or a' due to the expansion and contraction of the materials 9, 9, etc. By moving freely within a range of In addition, when the tiles to be fired are stacked in several tiers above and below, the left and right vertical walls 10 are
, The tile support is made of material 9 in parallel with an appropriate distance between the lower part of the space.
, 9 are constructed and used by stacking them.

In the present invention having the above structure and function, the bottom surface of the tile to be fired is supported by the top edge of the tile support, and even if it is tilted, it only contacts the upper end of the tile support rod, and the bottom surface of the tile to be fired is not connected to the tile to be fired. There are very few contact areas with the ingredients, so there is no chance of uneven baking on the product, and there will be no deformation or cracking due to internal distortion of the tiles to be fired due to expansion and contraction caused by the high heat during firing.
Since the tile support is prevented by the movement of the material, the yield of the product is extremely good, and it has very good practical effects.

Claims (1)

[Scope of utility model registration request] A plurality of holes are drilled at predetermined intervals in the square grooves of a square lumber-shaped underframe with a longitudinal square groove recessed in the upper surface, and tile support rods are inserted in parallel into the holes, and tile support rods are inserted into the holes in parallel. In each square groove between the bars,
