Description

[Detailed Description of the Invention] The present invention rotates a glaze scattering part on tableware such as plates, tiles, roof tiles, etc. (hereinafter referred to as ceramics) to make the glaze into a mist bundle and scatter it onto the ceramics to be glazed. This relates to a pottery glazing machine that simultaneously applies glaze to the upper and lower surfaces of a lever.

Traditionally, pottery glazing machines were of the so-called gutter type or bump type, but these machines tend to cause unevenness because the glaze tends to accumulate on one side of the glazed object or in the recesses, and are unsuitable for mass production. It was hot.

Therefore, various so-called spray-type glaze scattering devices have been developed that spray glaze using a spray nozzle.

However, since the spray type uses a nozzle, the amount and range of glaze scattering is large, making recovery of the glaze troublesome and difficult, and the amount of glaze used increases, resulting in large losses (approximately 30 to 40%). In addition, it is uneconomical, and a large amount of air gets mixed in. Combined with the fact that the nozzle is clogged, the glaze is not completely atomized, and the concentration of the glaze becomes uneven, which tends to cause unevenness on the surface of the pottery. Moreover, as mentioned above, there is a lot of scattering, so a large dust collector is required.

Furthermore, there is a method in which glaze is emitted in a mist form from a group of doughnut-shaped disks to glaze tiles being transported on a conveyor, but the glaze cannot be uniformly applied to the top and bottom surfaces at once. There are various problems such as impossible, requiring large equipment and a large power source, and not being able to save labor.

Therefore, in view of the above-mentioned conventional problems, the present invention provides at least one pair of glaze scattering parts, in which the object to be glazed is rotatably disposed, and the glaze is applied to both upper and lower surfaces of the part in the form of fine mist bundles. As a result, the amount of air mixed in can be reduced, reducing the amount of glaze being scattered to objects other than the glazed object, making it easy to recover, eliminating waste of glaze, and eliminating the need for dust collectors. The purpose was to provide a pottery glazing machine that is compact and power-saving as a whole, produces a uniform mist bundle, does not cause unevenness on the glazed objects, and is suitable for mass production. be.

The present invention comprises a cylindrical body formed to be able to introduce a glaze as appropriate and provided with a predetermined number of rows of through holes in the axial direction from which the glaze can be sucked out, and a disc body that is rotatable around the cylindrical body. It consists of a number of diffusion roller bodies arranged in parallel at predetermined intervals, and by rotating the diffusion roller body, the glaze can be arbitrarily dispersed into a mist bundle through the gap formed between the disk bodies. At least one pair of glaze scattering parts capable of scattering in directions are provided in the casing spaced apart from each other in the upper and lower directions, and a glazed object is rotatably disposed between the glaze scattering parts so that the glaze can be scattered above and below the glazed object. This is a pottery glazing machine designed to glaze the underside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the gist of the present invention, an embodiment of a glaze scattering part according to the present invention and a pottery glazing machine equipped with the same will be described below with reference to the drawings.

First, the structure of the glaze scattering part 1 will be explained with reference to FIG. 1. The glaze scattering part 1 is a joint part 112 with one end closed and an opening at the other end bulged into a hemispherical shape. Furthermore, a through hole 1 through which the glaze introduced into the interior can be sucked out as described later.
A cylindrical body 11 having a predetermined number of rows of 11 arranged in the axial direction.
and a diffusion roller body 12 disposed in a loosely fitted manner so as to be rotatable around the cylindrical body 11.

The diffusion roller body 12 has bearing plates 12 at both ends thereof.
1a and 121b, the bearing plate 12a on the closed end side of the cylindrical body 11 is fixed to a main shaft 21 appropriately connected to the motor 2 described later and is rotatable, and the bearing plate 121b on the joint part 112 side is bearing 1
It is rotatably attached to the cylindrical body 11 via 13.

Further, in order to arrange a large number of disk bodies 122 in parallel between the bearing plates 121a and 121b, three sets (not limited to this number) of bolts 123 and nuts 124 (with washers and spring washers as appropriate) are provided. urge)
A spacer 125 is fitted onto the bolt 123 to form a diffusion zone S 2 by providing a gap between the disc bodies 122 and to form a diffusion zone S ₂ between the disc bodies 122 . It has been intervened.

Furthermore, this diffusion zone S ₂ communicates with a suction zone S ₁ formed by a hole 121 a that extends through the center of the disc body 122 and has a diameter larger than that of the cylinder body 11 . The glaze inside is first sucked out into this suction zone _S1 , and then the glaze is diffused into a mist bundle in a diffusion zone _S2 , forming a gap S in which it is scattered in a predetermined direction.

Note that the joint portion 112 of the cylindrical body 11 is connected to the conical fitting 1 of the connecting pipe 13 connected to the cylindrical body 11.
32, and a joint screw 14 is provided, which has a threaded part 131 provided on the outer circumferential surface of the fitting part 132, and a threaded part 141 provided on its inner circumferential surface to be screwed into the fitting part 132. to form a joint part O, and connect the joint screw 1.
By tightening and loosening 4, the direction of the through hole 111 of the cylindrical body 11 can be adjusted.

Further, an elbow 15 is connected to the other end of the connecting pipe 13, and by connecting an arbitrary glaze supply pipe (not shown) to the elbow 15, glaze can be introduced into the cylindrical body 11.

Next, the structure of the pottery glazing machine A equipped with the glaze scattering part 1 formed as described above is shown in Figs. 2 and 3.
This will be explained according to the diagram.

The pottery glazing machine A has three glaze scattering parts 1a, 1b, and 1c arranged in its casing _A1 (the positions may be movable). Three motors 2 are respectively provided on the outside of the casing A ₁ in order to be able to rotate the diffusion roller body 12 , and the tips of the main shafts 21 directly connected to the motors 2 are connected to the diffusion roller body 12 in order to transmit the rotation of the motors 2 . It is fixed to the bearing plate 121a of the bearing plate 121a.

The glaze scattering parts 1a, 1b, and 1c are arranged at positions corresponding to the vertices of a triangle. 1b operates to glaze the lower surface of the pottery P, and the glaze scattering section 1c is used to assist when cutting the pottery into a complicated shape.

Furthermore, the pottery glazing machine A is provided with a conveyor 3 for conveying the pottery P and a rotation imparting mechanism 4 for rotating the mounting table 35 of the conveyor 3.

The carrier 3 includes a rail 31, a trolley 32 that is appropriately transported on the rate 31, a frame-shaped frame that is vertically disposed on the trolley 32, has a pulley 33 at its lower end, and has a pottery P placed on its upper end. It consists of a support 34 on which a mounting table 35 is arranged, and the glaze scattering part 1a
It is possible to pass between 1b and 1c.

Further, the rotation imparting mechanism 4 includes pulleys 41 and 42 and a belt body 43 stretched between these pulleys. One of the pulleys 41 and 42 is rotationally driven by a motor (not shown), and the belt body 43 is It is being driven. In addition, when the pulley 33 of the conveyance body 3 passes through the inside of the casing _A1 , the belt body 43
In order to make sliding contact with the support 34 and the mounting table 35, the support 34 and the table 35, and eventually the pottery P, are formed to rotate between them.

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

First, each cylindrical body 11 of the glaze scattering parts 1a, 1b, and 1c is adjusted. That is, the glaze scattering part 1
The scattering direction and width of the glaze mist bundles from a, 1b, and 1c are determined by various conditions such as the rotation speed of the diffusion roller body 12, the glaze supply pressure in the cylindrical body 11, and the viscosity of the glaze. The through holes 1 of the cylindrical body 11 are arranged so that the glaze is scattered all over the pottery being transported by the cylindrical body 11.
Adjust the orientation of 11. This adjustment can be easily made by loosening the joint screw 14 of the joint part O,
By tightening the joint screw 14, the cylindrical body 11 is fixed again.

When the diffusion roller body 12 is rotated in this manner, the inside of the gap S becomes a negative pressure state, and the cylindrical body 11
The glaze is sucked out from the through hole 111 to the suction zone _S1 . This glaze is further transported in a spiral through the diffusion zone _S2 by the negative pressure and centrifugal force.
At this time, it is diffused under the influence of the negative pressure and centrifugal force, and is scattered in the form of a uniform mist bundle.

Next, once such a fog bundle is stably formed, if the conveyor 3 and the rotation imparting mechanism 4 are driven to transport the pottery P, it will automatically pass through this fog bundle, and both surfaces will be can be glazed at once.

In this way, the direction and width of the mist bundle can be adjusted freely, so the glaze is not scattered in unnecessary directions, a dust collector is not required, and the glaze can be easily recovered (the loss of glaze is 30~ 40%, while the merits of the proposal are approx.
10%), and because it passes through a uniform mist bundle while rotating, glazing can be applied evenly, making it extremely effective for mass production.

In the above embodiment, a case has been described in which the gap formed in the diffusion roller body has two configurations: a suction zone and a diffusion zone, but the present invention is not limited to this, and for example, through holes may be formed between each disc body Needless to say, if it penetrates, there is no need to provide a hole in the disc body to form the suction zone.

Further, the joint structure between the cylindrical body and the connecting portion is not limited to the above structure, and may be formed in any structure as long as the direction of the through hole can be easily adjusted.

In this way, the specific structure, shape, and
The size, structure and arrangement method of the pottery glazing machine to which it is attached may be arbitrarily determined within the scope of achieving the above-mentioned objects, functions and effects of the present invention, and these changes shall not be considered as part of the present invention. Needless to say, this does not change the gist of the Act.

As explained in detail above, the present invention provides a glaze scattering unit made of a diffusion roller body, which is formed by disposing a large number of rotatable disk bodies in parallel at predetermined intervals around a cylindrical body having a through hole. At least one pair is provided in the casing spaced apart from each other at the top and bottom, and the ceramic material to be glazed is structured so as to be rotatable between the two, so that by rotating the diffusion roller body, the space between the disk bodies is formed. The negative pressure and centrifugal force caused by the rotation generated in the gap between the glaze and the glaze make the glaze into a mist shape. By scattering, it is possible to apply glaze to both sides of the glazed object at once. Therefore, the amount of air mixed in is small, a uniform fog bundle can be formed, and the scattering to other than the glazed object can be reduced, making it easy to collect. This eliminates the waste of glaze, and furthermore, the glaze can be applied inside the casing, eliminating the need for a dust collector, making the entire device compact and power-saving, and producing a uniformly fine mist bundle. It is said that the practical benefits brought about by the present invention are extremely large, as the conventional problems can be easily and effectively improved, such as the ability to scatter the glaze, so that the glaze can be applied evenly to the glazed object, making it suitable for mass production. I have no choice but to.
