Abstract

PURPOSE:To eliminate a wear of an unreasonable force being exerted on a ceramics product during fixing of the ceramics product to a jig by fixing the ceramics products to the jig by means of thermoplastic resin and setting the jig to a grinding device to grind the ceramics product. CONSTITUTION:A ceramics product (tile) 2 is fixed to a jig 1 by means of thermoplastic resin 3, and the jig 1 is set to a grinding device to grind the ceramics product 2 by means of a grinding stone 12. As noted above, since the ceramics product 2 is fixed to the jig 1 by means of the thermoplastic resin 3, a fear of an unreasonable force being exerted during fixing is eliminated, and a fear of the ceramics product 2 being broken is eliminated.

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION Field of Industrial Application The present invention relates to a method for grinding ceramic products such as tiles.

(Prior art) When the surface of a ceramic product, such as a tile, is polished using a grinding device to achieve a beautiful finish (polishing), if the tile is fixed with a jig equipped with a clamping device, the tile is brittle and cannot be tightly tightened. There is a risk of it breaking. Therefore, clamping and grinding tiles with clamping devices should be avoided.

そこで、従来では、タイルを横ずれしないように板状の
治具の上に隙間なく並べて研削するようにしていた。
Therefore, in the past, the tiles were ground side by side on a plate-shaped jig without gaps to prevent them from shifting laterally.

削量が大きくなるからタイルに作用する研削力は増加す

(Problem to be solved by the invention) By the way, the surface of the tile is slightly uneven,
When grinding something like this with a whetstone, the amount of grinding increases on the convex portions, so the grinding force acting on the tile increases.

このようなタイルを固定することなく、単に治具上に隙

If such tiles are simply arranged without any gaps on a jig without being fixed, the grinding force will increase if the grinding wheel is grinding on a convex part of the tile surface, and the rotating grindstone will cause the tiles to fly off. The tile may crack due to impact force being applied to the tile.

In order to prevent such problems, the tile feeding speed was slowed down to prevent tiles from cracking or popping out, but this did not fundamentally solve the problem of cracking or popping out, and it was difficult to grind. It takes a long time.

Therefore, an object of the present invention is to be able to grind a ceramic product while it is fixed to a jig, so that the ceramic product does not crack or pop out during grinding, and that it can be ground while being fixed to the jig. To provide a method for grinding a ceramic product without fear of the ceramic product cracking.

After that, the jig 1 is set on the conveyor 11 of the grinding device. Then, the jig 1 is conveyed by this conveyor 11,
During the transportation process, the surface of the tile 2 is ground by the grindstone 12. During this grinding, even if an impact force is applied to the tile 2 due to fluctuations in the grinding force due to slight irregularities on the surface of the tile 2, the tile 2 is fixed to the jig 1 by the thermoplastic resin 3. From, the rotating whetstone 10
Problems such as being blown away by objects do not occur.

Moreover, the thermoplastic resin 3 has some elasticity, and this elasticity allows the tile 2 to move in the lateral direction, so when an impact force is applied to the tile 2, the tile 2
escapes in the lateral direction, and the impact force is absorbed by the thermoplastic resin 3.

このため、タイル2が割れを生ずるおそれはない。Therefore, there is no possibility that the tile 2 will crack.

After grinding the tile 2 with the grindstone 12, the jig 1
is removed from the conveyor 11, and the thermoplastic resin 3 is removed from the jig 1.
The tile 2 is removed from the jig 1 by peeling it off. In this case, since the hot melt adhesive constituting the thermoplastic resin 3 is easily peeled off at room temperature, the tile 2 can be easily removed.
