Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a glazing machine for tableware such as plates and architectural ceramic products such as tiles 9, and particularly for applying glaze in the form of extremely fine particles or bundles. 6. Concerning a glazing machine designed to apply glaze by scattering (prior art) Conventionally, methods such as dipping, spraying, glazing, and lacquering were used to glaze pottery, but all of these methods have been developed in recent years. The mass production method had problems in terms of glazing speed, non-uniformity of glaze thickness, economic efficiency, etc., and was difficult to adapt to.

In view of J-Note, various types of glaze scattering devices have been proposed in recent years that use a spray nozzle to spray the glaze, but since the spray force type uses high-pressure air, the volume of air is large, and the scattering range is still limited to the nozzle. Since the glaze spreads radially from the glaze, a large amount of glaze is used and it is difficult to recover. Furthermore, if the nozzle is clogged, etc., the glaze may not be completely atomized, which tends to cause unevenness in the glaze 15, and the glaze will be scattered over a wide area as shown in L, requiring additional equipment such as a dust collector. The dog had various defects such as becoming curly.

(While the invention is trying to solve the problem) Therefore, the inventor of the present application developed a cylindrical structure in which the glaze is introduced and suction holes are arranged in order to replace the one-spray system. ! First, a diffusion roller consisting of a plurality of disk bodies that rotate together and are arranged at predetermined intervals is rotated, and the air between each disk body is blown outward by centrifugal force. A glaze scattering device for a pottery glazing machine, which utilizes the generated negative pressure to uniformly scatter the glaze sucked out from the suction hole into a shape (by the centrifugal force) onto the surface of the pottery to be glazed. Invented this and published it as special issue No. 169270/1984! did. The present invention has a conventional injection force type of 3
Glaze loss, which used to be 0-40%, has been reduced to about 10%.
In addition to these, the inventor of the present invention has also invented a glazing machine that can create a finer and more varied dew shape and apply a richer variety of glazes. It is.

(Step F to solve the problem) Therefore, the present invention introduces the glaze and provides a large number of fine holes through the outer periphery of the tubular supply tower, which is made up of rows of through holes that can be supplied without any glaze. Provided is a glazing machine, characterized in that at least one cylindrical scattering cylinder is rotatably disposed, and the glaze is formed into a dew by rotation of the scattering cylinder so that it can be scattered. This solves the above problems.

(Function) The present invention, which is constituted by the above-mentioned stage, is a glazing machine that has passage openings at the front and back, through which the glazed pottery passes continuously, and which is placed between the glazed pottery conveyance path and the glazed pottery. (Both two flying: i

Glaze is introduced into each of the scattering supply pipes and the scattering tubes are rotated simultaneously, and the glaze is supplied to the inner wall of the rotating scattering tube through the through-hole rows of the three supply tubes and instantaneously finely dispersed by centrifugal force. It is crushed to a dew-like consistency.

The glaze is then uniformly scattered over the entire surface of the pottery to be glazed. The individual powders that make up the frost bundle at this time are
Due to the centrifugal force caused by the rotation of the five tubes, the space formed between the supply tube and the dispersion tube always exhibits a negative pressure arch, and the supplied glaze is easily fractionated and separated from the dispersion tube. It collides with the inner wall and is shattered, and is further sucked out by the negative current flowing out from the micropores at high speed, forming extremely fine bundles of frost, and does not clog the micropores.

(Embodiment) Subsequently, an embodiment of the present invention will be described using FIGS. 1 to 3.

The scattering device 1a is located on the 17ij rear wall portion Wf of the casing AC.
Three bearing holes are drilled in each of the casing AC and Wr. Place the motor 132 on each of the mounting shelves 132s, have the shaft end protrude into the gauging AC, and press ■Boo 1.+
Arrive 1υ of 333. Then, the V pulley 133 and the V pulley 131 are connected by a V belt 134. After that, the elbows 14 are screwed onto the supply pipes 11-1, which are not provided at 3, protruding from the front wall Wf of the casing AC, and the ports H
The glaze is connected to the glaze tank Y, which is connected to the glaze tank Y, which is connected to the glaze tank Y, which is connected to the glaze tank Y, which is connected to the glaze tank Y, which is connected to the glaze tank Y, which is arranged in a part of the t and connected to the glaze tank Y, which is connected to the glaze tank Y by using a screwdriver. Further, in the glaze tank Y, a float (not shown) or the like is used to keep the glaze liquid level at a negative level, so that the pressure of the 3M chemical fed into the supply pipe 11 is kept constant.

Further, on-off valves 15 are respectively screwed onto the three supply pipes 11 protruding from the rear wall portion Wr. At this time, it is necessary that the through holes 111, -11 of the supply pipe 11 face the lower blade when the screwing is completed.

The glazing machine A is provided with a conveyor 2 for conveying the pottery P to be glazed, a rotation imparting mechanism 3 for rotating the ft of the conveyor 2, and a mounting table 25.

The conveyor 2 includes a rail 21, a trolley 22 that is appropriately transported on the rail 211, and is vertically installed on the match 1122, and a pulley 23 is placed on the do end of the conveyor 2, and the pottery P to be glazed is placed on the - end. It consists of a support 24 on which a frame-shaped mounting table 25i is disposed, and allows the scattering device 1a to pass therethrough as described above.

The rotation imparting mechanism 3 includes a pulley 31, another boob, and a belt body 32 stretched over these.The boob 931 is driven by a motor (not shown) to rotate the belt body 32.
2 is now being driven.

In addition, since the pulley 23 of the conveying body 2 comes into sliding contact with the belt body 32 when passing through the inside of the casing AC, the pulley 23 of the conveying body 2 is formed so as to rotate the support 24 and the mounting table 25, and eventually the pottery P to be glazed. There is.

Next, the operation of the glazing machine A formed as described above will be explained.

First, the three motors 132 of the scattering device la are started to rotate each of the scattering tubes 12. Next, 1 of the drug tank Y. Open the stopper not shown in , and introduce the glaze into each supply pipe ll and supply it from the through hole 111. Then, the opening and closing jr 15 are adjusted so that the ideal mist is scattered over the entire surface of the pottery P to be glazed.

After completing the adjustment as described in 1- above, the citrus breast ware P is placed on the carrier 21-, and the citron breast ware P is continuously passed through the glazing machine A.

At this time, inside each of the scatterers 1, the air inside is brought into a negative pressure state by the centrifugal force caused by the rotation of the Mjfa 12, as described above. The glaze supplied from the through hole 111--1 is in a very unstable state on the verge of splitting and is first sprayed through the hole 122b.
The mist particles collide with the fog, are instantly shattered, are blown away through the mesh, and are shattered again by the forming tube 122a, so that each mist droplet making up the mist is extremely fine and uniform in size. It is glazed with a very uniform thickness.

In addition, since the three scattering machines 1 scatter the mist from around the pottery P to be glazed, the entire surface can be glazed at once, which is very efficient. Further, in the present invention, the on-off valve 15 is provided at the end of the supply pipe 11.

It is easy to adjust the mist scattering state, and even if the dew scattering state changes for some reason during the operation of the glazing machine A, the machine will not be lost, and the adjustment can be made even while the operation continues. Since the entire amount of glaze remaining in the supply pipe can be discharged and recovered when fully opened, it is certain that the glaze loss rate, which was reduced to around 10% in the previous invention, will be further reduced by several percentage points. .

In the embodiment L, the spray tube 12 is made of a fine V1 wire mesh or the like. Although the P tube 122a and the inner fabric tube 122b have been described as having a concentric solid single-layer structure, the present invention is not limited to this, and the present invention is not limited to this. Alternatively, if the layer weight is 1, a cylinder made of wire mesh or the like and a metal plate etc. may be used in combination, depending on the nature of the glaze or the coating. Needless to say, the selection may be made appropriately depending on the shape and material of the glazed pottery.

I-1 Driving force method of the scattering tube 12, support of the scattering tube 12]
The specific structure, shape, and size of each part of the spraying device according to the present invention, the structure of the glazing machine to which it is attached, the method of arranging it, etc., are as follows: 1. Any changes may be made within the scope of the present invention (although it goes without saying that these changes do not change the gist of the present invention in any way).

(2) As explained in detail below, the present invention has a structure in which a rotatable spray tube is provided around the supply pipe that fills the through hole. This allows the glaze to be scattered in any direction by the negative pressure generated in the gap formed between the supply pipe and the centrifugal force applied to the spray tube, thereby preventing air from entering. In addition to being able to form a small amount of uniform powder, it also reduces scattering to objects other than the object to be glazed, making it easy to collect pql, and eliminating waste of glaze by using an on-off valve at the end of the supply pipe. In addition, the entire device can be compacted without the need for a dust collector, making it energy-saving.Also, since it can be dispersed in a uniform, ultra-fine h-shape, the glaze can be evenly applied to the glazed object with a uniform thickness, making it suitable for mass production. 1) Various mist conditions can be formed depending on the layers, number and combination of cylinders, and the problems of the conventional technology can be improved very simply and effectively, which is brought about by the present invention. It must be said that the actual benefits will be extremely large.
