Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a tile side belt finishing device, and more particularly to a tile side belt finishing device for removing glaze deposited along the sides of a glazed tile.

[Prior Art] As is well known, tiles are manufactured through four steps: a molding process, a first firing process, a glazing process, and a second firing process.

In the forming step, the powder raw material is pressed to produce a tile base. Then, the manufactured tile base is bisque fired in a first firing process and sent to a glazing process. In the glazing process, glaze is applied to the surface of the unglazed tiles, and patterns and colors are printed as necessary. The glazed tiles are then fired in a second firing step to become tiles as final products.

Here, in the glazing step, when the tile surface is glazed, a part of the glaze applied to the tile surface often spreads from the surface to the side surface. especially,
When the curtain-type glazing device shown in FIG. 6 is used, the tile 10 is passed in the direction of the arrow through the glaze 12 flowing out from the curtain can 14 like a curtain, so that a large amount is deposited on the side surface 10a of the tile 10 when passing through the curtain. The glaze 12a gets wrapped around.

However, if the tile 10 is sent to the second firing process with the glaze 12 still attached to the side surface 10a, the glaze 12 on the side surface 10a of the tile 10 will melt and wrap around to the back side, degrading the quality of the tile 10.
For example, a problem arises in that the adhesive force when attaching the tile 10 to a wall surface decreases.

In addition, when the melted glaze 12 gets around to the back side of the tile 10, the glaze adheres to the conveying roller installed in the firing furnace, creating unevenness on the roller surface, which causes the next tile to be fired. A problem arises in that it meanderes inside the furnace.

Therefore, the side surface 10 of the glazed tile 10
It was necessary to reliably remove the glaze adhering to the tile a, and a tile side belt finishing device (Utility Model Application No. 107340/1983) shown in FIG. 8 has been used.

In this conventional device, when the tile 10 is conveyed, the tile 10 is
The glaze 12 adhering to the side surface 10a is scraped off.

Then, the glaze dregs adhering to the belt 22 are scraped off by the dregs removing jig 26 as the belt 22 rotates, and collected in the glaze dregs receiving box 28.

[Problems to be solved by the invention] However, as shown in FIG. 7, the scrap removal jig 26 has a semicircular groove 26a having the same size as the diameter of the belt 22 formed at the tip of the flat plate. Since the glaze residue adhering to the belt 22 was scraped off, only the groove contacting surface of the belt 22 would become unevenly worn after long-term use. For this reason, there was a problem in that the contact between the belt 22 and the tile side surface 10a deteriorated, and the ability to remove the glaze adhering to the tile side surface 10a gradually decreased.

Furthermore, when the belt 22 wears unevenly, the state of contact between the belt 22 and the scum removal jig 26 also deteriorates, making it impossible to sufficiently scrape off glaze scum from the belt 22. For this reason, there was a problem in that the remaining glaze scum was scattered onto the surface of subsequent tiles due to falling due to vibrations during rotation of the belt or falling naturally due to gravity, resulting in the occurrence of defective tiles.

The present invention was developed in view of these conventional problems, and its purpose is to reliably remove glaze scum adhering to the belt without causing uneven wear of the belt, and to improve the finish of the side of the tile. It is an object of the present invention to provide a tile side finishing device that can be satisfactorily finished.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an apparatus for scraping off glaze adhering to the side surface of a tile using a belt that rotates in contact with the side surface of the tile, the belt being washed with a cleaning liquid. The belt includes a cleaning means, a dirt removal means for wiping off glaze residue adhering to the surface of the belt washed with the cleaning liquid, and a blower means for blowing gas so as to blow the cleaning liquid onto the belt from which dirt has been removed.

[Operation] The device of the present invention first washes the belt from which the glaze adhering to the side of the tile has been scraped off with a cleaning liquid.

Next, the glaze residue adhering to the surface of the belt that has been washed with the cleaning liquid is wiped off using a dirt removing means, and then the cleaning liquid adhering to the belt surface is blown away using a blower means.

As a result, the glaze residue adhering to the belt is almost completely removed without causing uneven wear on the belt, and it is possible to always use a clean belt to scrape off the glaze adhering to the sides of the tiles that are being conveyed one after another. can.

In particular, according to the present invention, glaze scum attached to the belt can be removed without causing uneven wear, so the tile side surface and the belt can always be kept in a good contact state, making maintenance easier. It will be easy.

As a result, the cleaning liquid adhering to the surfaces of the finishing belts 30 and 32 is blown away downward while passing through the through holes 82.

The present embodiment has the above configuration, and its operation will be explained next.

When the tiles 10 are conveyed one after another by the conveyor belts 16, 16, the side surface 10 of this tile 10
The glaze adhered to the upper surface 10b and the upper surface 10b is removed by the four side finishing belts 30 and 2 as shown in FIG.
The upper surface of the book is scraped off using a finishing belt 32. At this time, some of the scraped glaze scum falls off due to its own weight, but some remains attached to the belts 30, 32. The glaze residue adhering to the belts 30, 32 is first washed away by the cleaning liquid 62 sprayed in a shower-like manner, and further wiped cleanly by the sponge 72a of the wiping roller 72 which is driven to rotate in the opposite direction to the direction of movement.

However, when these finishing belts 30 and 32 are used as they are and come into contact with the side surface 10a and the top surface 10b of the tile 10, a part of the glaze is melted by the cleaning liquid and a striped pattern called water glue is formed along the edge of the tile surface. This can lead to defective tiles.

Therefore, when the finishing belts 30, 32 pass through the blower section 80, draining air is blown to remove the cleaning liquid adhering to the surfaces. As a result, dirt is completely removed from the side surface 10a and the upper surface 10b of the tile 10, and the finishing belts 30, 32 are free from the cleaning liquid 62.
This makes it possible to always finish the side surface of the tile 10 well.

In particular, according to the present invention, the glaze scum adhering to the surfaces of the finishing belts 30 and 32 is not forcibly scraped off unlike in the prior art.
0 and 32 do not occur, and once the contact between the finishing belts 30 and 32 and the side surface 10a and the upper surface 10b of the tile 10 is adjusted, a good contact state can be maintained.

Furthermore, in this embodiment, each finishing belt 30, 3
2 are twisted and joined, the position of the circumferential surface of the finishing belts 30, 32 in contact with the tile 10 constantly changes, and it is possible to prevent uneven wear from this surface as well.

After finishing the series of side surfaces, the tile 10 is then rotated 90 degrees in the horizontal direction, and the glaze on the side surface 10a and the top surface 10b of the tile 10 is scraped off using a similar device, so that all the sides of the tile 10 are finished. It can be finished well.

Note that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.

For example, by spraying a portion of the cleaning liquid 62 directly onto the sponge 72a of the wiping roller 72, it becomes possible to more clearly squeeze out the glaze residue adhering to the sponge 72a.

Further, as shown in FIG. 9, the belt cleaning section 6
0 may fill the water storage tank 64 with a cleaning liquid 62, and use the cleaning liquid 62 to simultaneously clean the belts 30 and 32 as well as the wiping roller 72 itself. In this case, in order to completely remove the cleaning liquid 62 attached to the belts 30, 32, a plurality of blower sections 80 may be provided in series, and a suction section 90 may be provided at the subsequent stage as shown in the figure. The cleaning liquid adhering to the belt surface may be sucked up.

Furthermore, in the embodiment, the finishing belts 30, 3
Although the case where a round belt is used as an example has been described as No. 2, the present invention is not limited to this, and flat belts and other belts may be used as necessary.
