Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a tile which is glazed and fired so as to have excellent stackability.

(Conventional tile and its problem to be solved) A tile that is glazed and then fired is inspected for the completion of the glazed surface (hereinafter referred to as the glazed surface) and the dimensional accuracy variation on the peripheral side, and is shipped. Sometimes, they were stacked in boxes for packaging. However, the tiles are usually glazed on one side of the flat surface and not glazed on the other side, so stacking the tiles sometimes caused scratches on each glazed surface. Since the scratches on the surface seriously impair the value of the tile as a product, it is not possible to put such scratched tiles on a general sales route to flow. Therefore, in order to prevent such scratches on the glazed surface, when stacking the tiles, it was necessary to interpose a pad material made of a resin material or corrugated paper between the tiles. This intervention work was extremely troublesome. Further, since the pad material is interposed, the bulkiness after stacking is inevitably large, which makes the handling inconvenient and the cost also increases.

The present invention has been made in view of the above circumstances, and prevents the glazed surface from being scratched without stacking pad material during stacking. It is intended to provide a new tile having excellent stackability (hereinafter, referred to as a tile of the present invention).

[Structure of device] (Means for solving the problem) The gist of the present invention is to disperse an ultra-thin cushioning material containing talc as the main material on the back surface of a tile after firing whose surface is glazed. It is in the place where it was attached.

(Operation) Since the cushioning material is made of talc, it is softer than the vitrified glazed surface and has less friction. Therefore, the glazed surface is not damaged by stacking.

Since talc is a ceramic and has a high heat resistant temperature, even tiles that have not been sufficiently cooled immediately after firing can be applied to the back surface thereof. Therefore, the firing step and the buffer material attaching step can be continuously performed.

Furthermore, since the thickness of the cushioning material can be made extremely thin by using talc, the height when stacked can be kept low.

(Embodiment) The present invention is described below with reference to the drawings showing each embodiment.

FIG. 1 is a perspective view of the tile of the present invention with its glazed surface 1 facing downward. The main tile is glazed surface 1
A plurality of cushioning materials 3, 3, ... Are scatteredly attached to a surface 2 (hereinafter, referred to as a non-glazing surface) on the opposite side to the two opposite sides. In addition, reference numeral 7 in the drawing is a foot forming concave portion for exhibiting an anchoring effect when the tile of the present invention is attached to a wall surface of a body or the like.

The cushioning material 3 is made of talc. Therefore, its hardness is 1 in Mohs hardness.
It is about 1.5. Since the Mohs hardness of the glazed surface 1 is generally about 5 to 7 in the vitrified state, it is clear that the cushioning material 3 is considerably softer than the glazed surface 1. That is, when the tiles of the present invention are stacked, a gap is formed between the glazed surface 1 and the non-glazed surface 2 in accordance with the thickness of the cushioning material 3 attached. No scratches on 1.

In order to attach the cushioning material 3 to the non-glazing surface 2, the following means are optimal. That is, as shown in FIG. 2, talc is slurried and stored in a tank 4, and a gear-shaped talc transfer tool 5 is forcibly rotated or freely rotatable in the tank 4. Then, the tiles to be conveyed after firing may be mounted above the talc transfer tool 5. If the talc transfer tool 5 is installed in the vicinity of the carry-out port of a firing furnace 6 such as a roller hearth kiln, the talc will adhere to the tiles that still have the firing residual heat. Therefore, the talc is dried quickly, which is convenient.

(Examination of Another Mode) The adhesion state of the cushioning material 3 to the non-glazing surface 2 is not limited to that shown in FIG. For example, they may be dispersed so as to form a quadrangle near the center of the non-glazing surface 2. In addition, it is also possible to attach them in a line drawing shape using a dispenser or the like. As described above, the configuration and shape of the tile of the present invention can be appropriately changed according to the embodiment.

[Advantage of Invention] As is clear from the above description, the tile having excellent stacking ability according to the present invention does not scratch the glazed surface due to stacking. Therefore, it is possible to improve the overall yield related to the production of tiles without lowering the product value as tiles. Further, since it is not necessary to interpose a pad material or the like for stacking tiles, stacking work can be facilitated, cost can be reduced, and handling can be facilitated. Since talc is a ceramic and has a high heat resistant temperature, even tiles that have not been sufficiently cooled immediately after firing can be applied to the back surface thereof. For this reason, the firing step and the buffer material attaching step can be continuously performed, so that the manufacturing time does not increase significantly due to the addition of the treatment step, and the tile production efficiency is good. Furthermore, since the thickness of the cushioning material can be made extremely thin by using talc, the height when stacked can be kept low. Therefore, a number of excellent advantages such as the number of tiles that can be stored per storage box can be increased.
