Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an apparatus for spraying a glaze liquid by spraying a glaze liquid on the surface of a glazed object such as a tile molding.

(Prior Art) Generally, when applying a glaze liquid to the surface of the object to be glazed, while passing the object to be glazed through a glaze box by a belt conveyor or the like,
A glaze liquid is sprayed in a mist from a glaze nozzle placed inside the box and sprayed onto the surface of the object to be glazed.

At that time, a considerable amount of glaze liquid passes through the object to be glazed downward.Therefore, in the case of a conventional glazing device, it was taken out of the upper glazed box that was received by the saucer and passed through a sieve to create an independent glaze that was installed near the glazed box. It is designed to be stored in a liquid tank. Then, a new glaze solution is replenished in this tank, and they are combined and supplied again to the glaze nozzle.

(Problems to be solved by the invention) However, the conventional glaze apparatus of this type has the following drawbacks due to the fact that an independent glaze solution tank is separately provided outside the glaze box.

The inside of the glaze box needs to be cleaned every time the type of glaze liquid changes, and an automatic cleaning device has been developed as a device for that purpose. This automatic cleaning device sprays cleaning water from the jet nozzle and rotates the jet nozzle and moves it up and down to clean the entire inside of the glazed box. It is possible to wash easily and efficiently in a short time.

However, if the glaze solution tank is independently provided outside the glaze box, it is necessary to wash only this tank separately from the glaze box. This work has to be done manually by the operator, and therefore, when the glaze solution is replaced relatively often, this cleaning work requires a great deal of time and labor, and the glazed box is automatically operated. Even if the cleaning device can efficiently perform the cleaning, a lot of time is spent for the setup change such as the cleaning operation of the glaze solution tank and the like, which causes a problem that the production efficiency cannot be sufficiently increased.

In the case of the conventional glaze device, the glaze solution taken out from the saucer of the glaze box is dropped onto the sieve and put in the glaze solution tank, that is, the inside of the glaze solution tank is opened to the outside atmosphere. Due to this, impurities may enter the inside of the tank, which changes the viscosity of the glaze solution and causes a slight change in the color of the glaze applied to the surface of the glazed object after firing. It was happening.

(Means for Solving the Problems) The present invention has been made to solve such problems, and its gist is to arrange a glaze nozzle inside a glazed box and to carry out the glazed box by a predetermined conveying means. In a device for spraying a glaze liquid in a mist state from the glaze nozzle to a glazed product passing inside, the lower part of the glazed box, the glaze liquid that has passed through the glazed product and a newly added glaze liquid Is configured as a liquid storage tank for storing and, the glaze liquid in the liquid storage tank is guided to a high tank by a conduit and a pump, and is supplied to the glaze nozzle from the high tank, and a new liquid is added to the liquid storage tank. There is a refill port for the glaze liquid.

(Operation and effect of the invention) Thus, the present invention configures the lower part of the glaze box as a tank for the glaze solution, and stores the glaze solution that has passed through the object to be glaze in this tank and replenishes the new glaze solution here. And supplies them to the glaze nozzle through a high tank.

This eliminates the need for an external glaze solution tank, which is conventionally required, reduces the number of parts in the device, and saves space for the tank.

According to the present invention, there is an advantage that the cleaning operation when changing the type of glaze is extremely simple.

As described above, the present invention does not independently provide a glaze liquid tank outside the glaze box, but configures the lower part of the glaze box as a glaze liquid tank, and the glaze liquid taken out from this is directly passed through the conduit to the glaze nozzle. Because I am trying to lead
If the conduit is connected to the drain port, the entire apparatus can be cleaned by the above-mentioned automatic cleaning apparatus, and the cleaning can be performed efficiently in a short time. Therefore, even when the type of glaze liquid is frequently changed, the time ratio required for cleaning is reduced, which greatly improves the production efficiency.

Further, since the glaze solution can be circulated in the closed system, the device of the present invention has an advantage that impurities are less likely to be mixed into the glaze solution from the outside and the color development state of the glaze can be made uniform.

In the present invention, it is desirable to provide a sieve at the glaze solution take-out portion from the glaze solution tank to the conduit, which can prevent the solid content from being guided to the glaze nozzle.

According to the present invention, a new glaze solution replenishment port is provided in the glaze solution tank. According to the present invention, the glaze solution can be supplied from the outside of the glaze box into the tank through the replenishment port. According to the invention of claim 2, by providing an indicator for indicating the liquid level of the glaze liquid in the tank, the glaze liquid in the tank can be seen even if the inside of the glazed box cannot be seen from the outside due to the adhesion of the glaze liquid. It is convenient because the glaze solution can be replenished at an appropriate time after knowing the amount.

(Example) Next, the Example of this invention is described in detail based on drawing.

In Fig. 1, 10 is a glazed box, inside which is a glazed nozzle.
12 are arranged so as to be swingable in the horizontal direction. This glaze nozzle 12 is composed of an air nozzle 14 and a glaze liquid nozzle 16, and sprays the glaze liquid discharged from the glaze liquid liquid nozzle 16 in a mist state by the air pressure from the air nozzle 14.

Reference numeral 17 denotes a belt conveyor, which allows the tile molded body 18 to pass through the inside of the glazed box 10 and the surface of the glazed box 10 is coated with a glaze liquid.

The lower part of the glazed box 10 is a glaze solution tank (storage tank) 20.
Is configured as. The glaze liquid tank 20 has a shape in which the cross-sectional area gradually decreases as it goes downward, and the glaze liquid that has passed through the tile molded body 18 downward has the shape of the tank 20.
In addition to being received at, it is now being stored.

As shown in FIG. 2, a cylindrical sieve 22 is disposed at the bottom of the glaze solution tank 20, and the glaze solution in the tank 20 is taken out through this sieve 22 to an external conduit 24, Further, the pump 40 (FIG. 1) lifts it up to the high tank 42, and then it is supplied to the glazed nozzle 12 by gravity.

As shown in FIG. 2, a replenishing port 28 having a lid 26 that opens up and down is provided at the front of the glaze liquid tank 20. The refilling glaze liquid is supplied from the replenishing port 28 into the tank 20. It is supposed to be poured.

As shown in FIG. 1, floating balls 30 are arranged in the tank 20. As shown in detail in FIG. 3, the floating ball 30 is fixed to the tip of a lever 32, and the base end of the lever 32 is connected to a rotating shaft 34. Is designed to be rotated. One end of the rotary shaft 34 projects outside the tank 20, and an indicator needle 36 is provided at the tip thereof so that the amount of liquid in the tank 20 can be known from the outside by the indicator needle 36 and the scale 38. It has become.

In the apparatus of the present example, of the glaze liquid sprayed from the glaze nozzle 12, the portion passing through the tile 18 downward is received by the glaze liquid tank 20 and stored therein. In addition, this tank 20 is replenished with a new glaze solution, and after they are combined and passed through a cylindrical sieve 22 at the bottom, they are guided to a high tank 42 by a conduit 24 and a pump 40, and from there to a glaze nozzle 12. Supplied.

Thus, in the apparatus of this example, since the bottom of the glaze box 10 is configured as the glaze solution tank 20, a dedicated tank for glaze solution storage is provided outside the glaze box 10 like the conventional glaze apparatus. This simplifies the device, and at the same time, greatly simplifies the cleaning of the device when changing the type of glaze solution. Glaze liquid tank
This is because the entire glazed device can be washed simply by guiding the tip of the conduit 24 from 20 to the drain port and then washing the inside of the glazed box 10 with the automatic washing device.

Note that this is only one embodiment of the present invention, and the present invention can be applied, for example, when glaze is applied to a glazed object other than the above tile, and a glaze liquid tank and the like are also included within the scope of the present invention. It is also possible to make appropriate changes based on the knowledge of those skilled in the art.
