Abstract

(57) [Summary] [Purpose] Prevent foreign substances and dust from entering from the pump etc. to adhere to the surface of the tile body to be glazed. Also, it prevents clogging of the glaze nozzle. [Configuration] In a device for discharging glaze to a glaze nozzle 18 by utilizing the head pressure in the high tank 13, a glaze discharge port 17 in the high tank 13 is provided above the suction port 15.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a glazing apparatus for glazing a tile body or the like.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 2, for example, as shown in FIG. 2, a device for glazing the tile body 1 pumps the mixed glaze stored in the glaze tank 2 to the upper part of the high tank 4 by the action of the pump 3, and the high tank 4 The glaze was supplied from the bottom of the high tank 4 to the glaze nozzle 5 by utilizing the head pressure of the glaze inside. Then, the glaze was sprayed from the glaze nozzle 5 onto the upper surface of the tile body 1 in a uniform mist to apply the glaze.

[0003]

[Problems to be solved by the device]

 In such a conventional glazing apparatus, it is necessary to prevent foreign matter from entering the pump 3, and therefore a diaphragm pump is generally used.

However, depending on the glaze component, foreign matter, dust, and the like of the pump material may still enter the high tank 4, and these may accumulate at the bottom of the high tank 4 and reach the glaze nozzle 5 by the head pressure of the glaze. It may be supplied and spouted onto the surface of the tile body 1. For this reason, there is a problem that foreign matter adheres to the surface of the tile body 1 to cause a defective product or cause clogging of the glaze nozzle 5.

[0005]

[Means for Solving the Problems]

 The glazing device according to the present invention is one in which the discharge port of the glaze in the high tank is formed at a position higher than the suction port.

[0006]

[Action]

 The glaze is accumulated inside the tank by the operation of the pump, for example, from an inlet formed at the bottom of the high tank. Then, the glaze is supplied to the glaze nozzle from the discharge port formed above the suction port. Therefore, even if foreign matter enters the high tank, it only remains at the bottom of the high tank and is not discharged to the glazed nozzle.

[0007]

【Example】

 Embodiments of a glazing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional view showing an outline of a glazing apparatus according to the present invention. In FIG. 1, the conveyor 7 is a means for conveying the tile base 8 from, for example, a dry press molding device (not shown) to a glazed booth which is a space to be glazed. The bottom wall 9 of the glazed booth is formed in a saucer shape, and a discharge pipe 11 is connected to a central portion 10 of the bottom wall 9 so that glaze components scattered around the glazed work can be collected in a glaze tank 12. ing.

The external shape of the high tank 13 is the same as the conventional one shown in FIG. 2, and the arrangement of the suction port and the discharge port of the glaze is different from the conventional one. That is, in the present example shown in FIG. 1, the bottom of the high tank 13 serves as an inlet 15 for pumping glaze from the glaze tank 12 by the operation of the pump 14, and this inlet is connected to the pump 14 via the hose 16. . A discharge port 17 for discharging the glaze is provided at a position above the suction port 15 and substantially in the center of the high tank 13. The discharge port 17 is connected to a glaze nozzle 19 via a hose 18.

Reference numeral 20 is a return port for adjusting the amount of glaze in the high tank 13, and is opened to the glaze tank 12 via a hose 21.

Therefore, when performing the glaze operation, the pump 14 is driven so that the water level of the glaze is maintained up to a position above the discharge port 17. Then, the glaze is discharged to the glaze nozzle 19 via the hose 18 by the head pressure of the glaze existing above the position of the discharge port 17. For this reason, even if foreign matter, dust, etc. enter from the pump 14 into the high tank 13 through the suction port 15 and may collect at the bottom of the high tank 13, they will not flow out from the discharge port 17 toward the glaze nozzle 19.

In this example, the discharge port 17 is formed at a substantially central position of the high tank 13, but at a position above the suction port 15, it can only discharge the glaze nozzle 19 with sufficient pressure. Of course, it is only necessary to secure the head pressure, and it is not limited to this position.

[0012]

[Effect of the device]

 As described above, according to the present invention, even if foreign matter, dust, or the like enters the high tank via the pump, it is not discharged to the glaze nozzle side. Therefore, no foreign matter is ejected from the glazed nozzle together with the glaze. In addition, the glaze nozzle is not clogged due to these foreign matters.
