Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a glazing device that sprays a slurry-like glaze onto the surface of a glazed object such as a tile.

(Prior Art) Conventionally, as a glazing device that sprays a slurry-like glaze onto the surface of a glazed object such as a tile, as shown in FIG. Air is ejected to atomize the glaze, and the spray main body 100 is rotated in the direction of arrow A in the figure to apply the glaze to the glazed portion 106 that is being conveyed in the direction of arrow B by a predetermined conveyance means such as a belt. Continuous spray application devices are known.

(Problem to be solved by the invention) However, since this glazing device sprays the glaze while rotating the spray part in a fixed position, the glaze is not efficiently applied to the surface of the glazed object, resulting in a lot of wasted material. There was a risk that a slight difference would occur in the amount of glaze applied to the objects to be glazed located at both ends in the width direction of the conveying means such as a belt and the object to be glazed located at the center.

(Means for solving the problem) The glazing device of the present invention was devised to solve the above problem, and its gist is to atomize a slurry-like glaze and apply it to the surface of the object to be glazed. A glazing device for spray coating, which has (a) a rod-shaped spray main body, which is horizontally rotated around a vertical pivot located at or near the base end; (b) A spray part that is provided with a downward nozzle at its tip and sprays the glaze in a mist form from the nozzle; (c) a cam follower provided on the reciprocating member; (c) a cam follower provided on the reciprocating member;
(D) A cylindrical cam having a convex or concave cam on its circumferential surface, into which the cam follower is fitted, and which reciprocates the reciprocating member as the cylindrical cam rotates;
and a driving means for rotationally driving the cylindrical cam.

(Operation and Effects of the Invention) In the device of the present invention, the spray main body reciprocates (swings) horizontally around the base end or the vicinity thereof, and sprays glaze from the downward nozzle at the tip thereof. In other words, the nozzle sprays the glaze while moving over a wide range in a substantially horizontal plane while maintaining the same distance from each object to be glazed, which is transported by a predetermined transport means. can be evenly applied to each surface of the glazed object. As a result, loss of glaze is suppressed to a minimum, and at the same time, the amount of glaze applied to each object to be glazed is made uniform.

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3, reference numeral 10 denotes a stand of the glazing device, on which a spray main body 12 is placed. The spray main body 12 is constituted by a rod-shaped member, and a glaze passage and an air passage are formed inside thereof along the longitudinal direction of the spray main body 12. Hoses 14 and 16 are connected to the base end of this spray main body 12, and these hoses 1
4 and 16, slurry-like glaze and air are introduced into the glaze passage and air passage inside the spray body 12. The glaze introduced into the glaze passage is discharged from the discharge port at the tip of the spray main body 12, and the discharged glaze is atomized by the air jet flow, and is discharged from the downward nozzle 18 at the tip of the spray main body. Sprayed from the tip.

The spray main body 12 is rotatably supported by a vertically oriented shaft 20 near its base end, and one end of a rectangular bar-shaped reciprocating member 22 is attached to a fixed member at a predetermined distance apart from the shaft 20. 24. Further, a pair of guide blocks 28 are fixed to the reciprocating member 22 by a fixing member 26, and these guide blocks 28 are fitted into guide rails 30 fixed on the pedestal 10, so that the reciprocating member 22 is fixed to the reciprocating member 22. It is designed to guide the movement of 22 people.

Also disposed on the pedestal 10 is a cylindrical cam 32 adjacent to the reciprocating member 22. Cylindrical cam 3
2 has a rotating shaft 36 rotatably supported by a bearing 34, and a sprocket 38 is fixed to one end of the rotating shaft 36, and a chain 40 is wound around the sprocket 38.
It is connected to a motor (not shown) via.

As shown in FIG. 2, an endless ring-shaped cam groove 41 is formed on the circumferential surface of the cylindrical cam 32.
A roller 42 as a cam follower is fitted therein. Therefore, this roller 42 is attached to the fixed member 4
4 to one end of the reciprocating member 22, and the movement of the roller 42 causes the reciprocating member 2
2.

In the device of this example, when the cylindrical cam 32 is rotated by a motor (not shown), the cam groove 41 on the surface of the cylindrical cam 32 is rotated through the roller 42.
A reciprocating member 22 connected to the reciprocating member 22 is reciprocated along a linear track under the guidance of a guide block 28 and a guide rail 30. Then the spray body 1
2 is reciprocated (swung) within a horizontal plane within a predetermined angular range around the shaft 20. At this time, the downward nozzle 18 is moved over a wide range while maintaining a downward attitude toward each glazed object and at an equal distance from each glazed object, and sprays the atomized glaze onto the surface of the glazed object. Spray on.

In this way, in the device of this example, the nozzle 18
Since the glaze is sprayed over a wide area while facing the surface of the glazed object, that is, facing downward, the glaze sprayed from the nozzle does not scatter sideways as in the conventional device, making it more efficient. It is sprayed onto the surface of the glazed object.

Although the embodiments of the present invention have been described in detail above, the present invention can also be configured in other forms.

For example, in the above example, the spray main body is constructed in the form of a rod, and the glaze passage and the air passage are formed inside the spray body, but the rod-shaped body is used as a mere support rod, and the glaze passage and the air passage are formed on the outer peripheral surface of the spray body. It is also possible to configure the spray main body by providing piping, or to configure the spray main body in other forms.

Furthermore, in the above example, a cam groove is formed on the surface of the cylindrical cam, and the cam follower on the reciprocating member side is fitted into this cam groove. It is also possible to form a groove in and fit the two together.

In addition, the reciprocating member may take various forms other than the above example, and the present invention can be constructed with various modifications without departing from the spirit thereof.
