DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for glazing tiles, and more particularly, to a method for glazing with curtains.

[0002]

2. Description of the Related Art As a method for glazing a tile surface, a curtain glaze is applied to a tile surface by containing a liquid glaze inside a container and discharging the glaze inside from a slit-shaped opening at the lower end of the container in a curtain. The method is widely practiced.

[0003] One type of tile is a chamfered tile having a chamfered end, which is used at a specific location during tile construction. In the case of this chamfered tile, there was a problem that it was not possible to satisfactorily apply the glaze when the glaze was applied by the conventional hanging glaze.

[0004] In the case where ordinary seed glaze is applied to this kind of chamfered tile, the applied glaze flows down along the chamfered surface in the chamfered portion, and as a result, in the chamfered portion. The thickness of the glaze becomes thinner, which causes the inconvenience that the same part can be seen through.

Therefore, in this case, spray glaze for spraying glaze in a mist state on the chamfered portion after the glaze is applied is partially applied.

[0006]

However, in this case, a separate spray glaze apparatus is required in addition to the glaze glaze apparatus, and the suitable glaze composition differs between the glaze glaze and the spray glaze. It is necessary to separately prepare two glazes, one for the curtain and the other for the spray.

[0007] In addition, when the spray glaze is partially applied later, the glaze spreads over a certain area and is applied to the tile surface, and in some cases, the glaze becomes uneven.

When a spray glaze apparatus is used, equipment such as a dust collecting apparatus and a glaze booth is required, so that the apparatus becomes complicated and a lot of space is required.

[0009]

The invention of the present application has been made to solve such a problem. Thus, the invention of the present application is a method for glazing a tile having a chamfered portion, in which a liquid glaze is first continuously discharged from the tip of a nozzle and the glaze is drawn along the top of the chamfered portion. Before the applied glaze does not dry out, discharge the liquid glaze in the container from the slit-shaped opening at the lower end of the glaze container in a curtain shape and apply the entire curtain surface to the tile. Features (Claim 1).

According to another aspect of the present invention, there is provided a glaze method according to claim 1, wherein a common glaze tank is used as a glaze supply source to the glaze container and a glaze supply source to the nozzle. A glaze having the same composition is supplied through the flow path (claim 2).

In another aspect of the present invention, in the glazing method according to claim 1 or 2, the tile is conveyed by a conveyor along a predetermined conveying path, and the glaze container and the glaze nozzle are arranged on the conveying path at a predetermined distance. In the process of arranging the tiles at a distance and passing the tiles below the glaze nozzle and the glaze container, the glaze by the nozzle and the glazing of the glaze by the glaze container are performed at a predetermined time interval. (Claim 3).

[0012]

As described above, in the first aspect of the present invention, first, a liquid glaze is applied linearly from the nozzle along the top of the chamfer. Then, glaze is applied to the entire tile surface by curtaining.

At this time, a part of the upper side of the glaze previously applied in a linear shape flows along the chamfered surface together with the flow of the glaze that has been hung later, while the remaining part of the lower side of the linear glaze is It will be in the same part.

As a result, the glaze is uniformly applied to the chamfered surface and to the same degree as the other tile surfaces. That is, the glaze is uniformly applied to both the tile surface and the chamfered surface.

If the order of the glazing by the nozzle and the glazing with the curtain is reversed, the glaze is not applied well to the chamfered surface. The chamfered surface becomes partially glazed.

[0016] On the other hand, when the glaze applied linearly from the nozzle is dried and then glaze-coated, the glaze is not applied well. Later, when the glaze was applied,
A part of the glaze previously applied in a linear shape does not flow well together with the glaze applied with the curtain, and the glaze remains at the top of the chamfered portion, causing a step.

According to the method of the present invention, a spray glaze apparatus is not required separately from a curtain glaze apparatus, so that the apparatus configuration is simple and the required space is small, and two glazes having different compositions are separated. Need not be prepared.

According to the second aspect of the present invention, the glaze is supplied to the glaze container and the nozzle from the common glaze tank. According to the present invention, the configuration of the apparatus can be further simplified.

Further, according to the third aspect of the present invention, the nozzle glaze and the curtain glaze can be automatically performed with a time lag simply by transporting the tiles along the predetermined transport path by the conveyor. The glaze can be satisfactorily applied to the chamfered tile.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 2, reference numeral 10 denotes a chamfer tile, and an R-shaped (curved) chamfered portion 12 is formed at one end.

FIG. 1 shows a method of glazing the tile 10 together with the apparatus configuration. In the figure, reference numeral 14 denotes a belt conveyor on which the tiles 10 are placed and transported along a predetermined transport path.

Numeral 16 denotes a nozzle arranged downward above the belt conveyor 14, and a liquid glaze 20 from the lower end.
Are continuously discharged.

On the downstream side of the nozzle 16, a glaze container 18 is arranged above the belt conveyor 14. A liquid glaze 20 contained in the interior of the container 18 is discharged in a curtain shape from a slit-shaped opening 22 at the lower end of the glaze container 18.

Reference numeral 24 denotes a glaze tank serving as a common glaze supply source for the nozzle 16 and the glaze container 18. The glaze 20 is stored inside the glaze tank 20, and the glaze 20 is supplied to the nozzle 16 or the container through flow paths 26 and 28, respectively. 18
To be supplied to

Next, the glaze method and operation of this embodiment will be described with reference to the schematic diagrams of FIGS. 1 and 3A. The tile 10 is conveyed to below the nozzle 16 by the belt conveyor 14, where the liquid glaze 20 continuously discharged from the lower end of the nozzle 16 is applied linearly along the top of the chamfer 12 (I ).

Tile 10 coated with glaze 20 in a linear manner
Is conveyed further downstream, and when it reaches the position where the glaze container 18 is arranged, before the glaze 20 applied in a linear shape has dried yet, the curtain is opened from the slit-shaped opening 22 at the lower end of the glaze container 18. The glaze 20 discharged in a shape is glazed over the entire surface of the tile 10 (II).

At this time, a part of the glaze 20 which has been previously glazed in a linear shape on the top is partly chamfered together with the glaze 20 with the glazed glaze.
While flowing downward along 2, the remaining portion of the glaze 20 applied linearly remains in the same portion (III).

As a result, the glaze 20 on the chamfered portion 12 is applied uniformly to the same extent as the other tile surfaces without reducing the thickness of the glaze 20 on the chamfered portion 12 (IV).

As described above, according to the present embodiment, the glaze 20 can be applied to both the chamfered portion 12 and other tile surfaces even if the glaze 20 is not partially sprayed on the chamfered portion 12 after the curtaining glaze.
Is uniformly applied. This eliminates the need for a spray glaze apparatus, simplifies the apparatus configuration and requires less space, and eliminates the need to separately prepare two glazes having different compositions.

In the method of this embodiment, the glaze 20 is supplied to the glaze container 18 and the nozzle 16 from the common glaze tank 24, so that the configuration of the apparatus can be further simplified. Furthermore, simply by conveying the tile 10 along the predetermined conveying path by the conveyor 14, the nozzle glaze and the curtain glaze can be automatically performed with a time lag, and the glaze on the chamfered tile 10 can be easily performed.
