Abstract

(57) [Abstract] [Purpose] When glaze is sprayed from one glaze high tank to multiple locations, it flows out to each connection hose 4, 5 due to twisting of the base hose 3 which is a common part. Prevents uneven color due to different glaze outflow. [Structure] Glazing nozzles 10, 1 on the bottom of the high tank 13
A plurality of exclusive discharge ports for 1 are formed.

[Industrial application]

 INDUSTRIAL APPLICABILITY The present invention relates to a glazed high tank, which is used in a so-called divided tile glaze process in which both sides of a tile base material have to be glaze.

[0002]

[Prior Art]

 The glaze process of the tile base is a process in which the tile base is transported by a conveyor etc. into the glaze booth, and the glaze nozzle is provided above the glaze booth to spray the glaze onto the surface of the tile base to apply it. Is. And, normally, the glaze accumulated in one glaze high tank was supplied to one glaze nozzle.

On the other hand, when the glaze is supplied from one glazed high tank to a plurality of (for example, two) glazed nozzles, as shown in FIG. 5, there is one spout formed at the bottom of the high tank 1. The base hose 3 connected to the outlet 2 was connected to the connection hoses 6 and 7 connected to the glaze nozzles 4 and 5, respectively.

[0004]

[Problems to be solved by the device]

 However, in the glazed high tank shown in FIG. 5, since the base hose 3 is a common part on the base side of the connection hoses 6 and 7, when the base hose 3 is twisted, the connection hoses 6 and 7 are connected. The amount of glaze flowing out is reduced unevenly in the glaze nozzles 4 and 5. For this reason, when using the glaze nozzles 4 and 5, for example, to tile each tile body having the same surface shape, the tile body that is glazed by one of the glaze nozzles 4 and the tile element that is glazed by the other glaze nozzle 5 are used. The amount of glaze sprayed to the glazed tile body was different, which caused uneven coloring. In particular, when glazing a large tile base, there was a problem that the color unevenness was noticeable.

[0005]

Means for Solving the Problems A glazed high tank according to the present invention has a plurality of exclusive discharge ports for a glazed nozzle formed on the bottom side.

[0006]

[Action]

 Dedicated discharge ports for multiple glaze nozzles are formed at the bottom of the high tank, and there is no common part in the hose connected from the high tank to each glaze nozzle, so fluctuations in the glaze injection amount due to twisting of these common parts are prevented. It is possible to prevent uneven coloring.

【Example】

 Embodiments of a glazed high tank according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view schematically showing a glazing process in which the glazed high tank according to the present invention is used, FIG. 2 is a vertical sectional view showing the inside of the glazed high tank and the glazed booth according to the present invention, and FIG. FIG. 4 is a perspective view showing a tile base material to be glazed in the example, and FIG. 4 is a side view showing a state in which a tile piece obtained by firing the tile base material shown in FIG.

In FIG. 1, a conveyer conveyor 8 is a conveyer means for sequentially moving a tile base material from a molding device (not shown) through a glazing booth 9 and a reversing booth 10. This molding apparatus is for dry-press-molding the kneaded material to obtain a tile base material. Although not shown, between the molding apparatus and the glazed booth 9, the kneaded material and the molding burrs attached to the tile base material are removed. A finishing device is provided. The glazed booth 9 is made of, for example, a greenhouse material.

As shown in FIG. 3, the tile base A used here is used for the production of so-called divided tiles, and includes a protrusion 11 at the front end, a recess 12 at the rear end, and a flat plate portion 13 at the center. Are formed so as to extend in the longitudinal direction, respectively, and notches 14, 14 for splitting are provided at the central positions of the projection 11 and the recess 12 along the longitudinal direction. After the glazing process and the firing process (not shown) are completed, this tile base material becomes the tile pieces 15 that are vertically divided by the notches 14 and 14 (see FIG. 4).

Returning to FIG. 1, the conveyer conveyor 8 is extended from the front position of the glazed booth 9 so as to bend outward and returns to the rear, and again inside the glazed booth 9 via the reversing booth 10. As a result, the conveyor 8 in the glazed booth 9 is extended to the rear end side and has two rows of horizontal conveyor paths. Then, in one of the transport paths, one surface B1 side of the tile base material A 1 is turned upside down, and in the other transfer path, the other surface B 2 of the tile base material A 2 is turned upside down.

The reversing booth 10 is for automatically reversing the front and back of the tile base A, and for example, a belt device (not shown) is used. That is, while the side portion of the surface B2 of the tile base A is placed on the belt device that moves slightly above the conveyer conveyor 8, the tile base is rotated by 90 degrees, and the belt device of the same type is passed through. It is rotated by 90 degrees again and inverted so that the surface B2 faces up.

Glazing nozzles 17 and 18 are arranged above the parallel conveying paths in the glazing booth 9 (see FIG. 2).

The glaze nozzles 17 and 18 are directly connected via two connecting discharge hoses 22 and 23 from two dedicated discharge ports 20 and 21 that are opened at the bottom of the high tank 19.

The glaze is supplied to the upper part of the high tank 19 from the glaze tank 24 by the operation of the pump 25. Reference numeral 26 is a return pipe for returning the glaze accumulated excessively in the high tank 19 to the glaze tank 24. Further, the glazed booth 9 has a bottom wall 27 inclined toward the center and a discharge pipe 28 connected to the central portion so that the recovered glaze is returned to the glaze tank 24.

In the glazed booth 9, however, the first surface B1 side of the tile base A and the second surface B2 inverted through the inversion booth 10 are respectively face up and conveyed in parallel. The glaze is sprayed from the glaze nozzles 17 and 18, respectively, and the glaze is applied.

At this time, the connection hoses 22 and 23 connected to the glaze nozzles 17 and 18 are directly connected to the dedicated discharge ports 20 and 21 which are the openings of the high tank 19, and the glaze nozzles 17 and 18 are also connected. Are held above the glaze booth 9 at appropriate intervals, the twisting of the connection hoses 22 and 23 does not occur, and the same amount of glaze is always supplied to the glaze nozzles 17 and 18. Therefore, the same degree of glaze can be applied to both sides of the tile base.

[0017]

[Effect of the device]

 As described above, according to the present invention, when the glaze is supplied from one high tank through the plurality of glaze nozzles, the glaze can be uniformly applied. Therefore, it is particularly preferable for the production of so-called divided tiles, which require the same degree of glaze on both sides of the tile.
