Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pottery rolling apparatus, and more particularly, to forming and firing pottery such as tableware and flower pots by a method called so-called "tatara making". The present invention relates to a porcelain clay rolling device for efficiently producing a clay.

[0002]

2. Description of the Related Art Tatara is generally made by hand, but there are also devices for performing this mechanically. Rolling is performed through a clay mass between rollers rotating in pairs, and the operation is repeated continuously in the same direction, and the operation is stopped once after the above-mentioned rolling, and the same operation is repeated. There is.

[0003]

The above-mentioned conventional porcelain rolling machines are not only expensive, but also have a wasteful time in which no rolling is performed between one rolling operation and the next rolling operation. The whole work takes time, the work efficiency is poor, and a circular rattle cannot be made. Especially, in the case of continuous repetition in the same direction, a large installation space is required.
Is necessary. Therefore, the present invention
It is an object of the present invention to provide a pottery clay rolling apparatus which can roll a pottery clay efficiently with a simple and compact configuration, saves space for installation, and can make a circular rattle.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a wheel,
A rotary plate driven by the rotary drive is mounted on a rotary drive means such as a tar, and a mat for holding the china clay is arranged on the rotary plate. The mat is freely rotated on the mat in contact with the upper surface of the mat. A roller support arm for supporting a plurality of rolling rollers to be rolled is provided, and one end of the roller support arm is mounted on an upright standing near the rotation driving means. The above-mentioned problem has been solved by a porcelain rolling apparatus in which a pressing force applying means is disposed at the mounting and other end portions.

[0005]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of the base, in which 1 is a base, 2 is an upright standing on one end of the base 1, and FIG.
An electric or manual wheel base 3 as a rotation driving means is provided on a base 1, and a rotating plate 4 is mounted on the wheel base 3. A motor with a speed reducer may be used instead of the wheel table 3 as the rotary drive means. A plurality of stoppers 5 for preventing the rotating plate 4 from dropping off may be provided on the periphery of the rotating plate 4. As described later, a rubber band may be used instead of providing the stopper 5.

The clay mass 6 to be rolled is a thin plate such as veneer,
It is placed on the rotating plate 4 while being sandwiched between mats 7 and 8 for preventing adhesion of plastic sheets, metal foils, nonwoven fabrics, fibers and the like. Reference numeral 9 denotes a roller support arm mounted on the standing plate 2, on which a number of freely rotating rolling rollers 10 are axially supported in a downward direction. The illustrated roller support arm 9 is rod-shaped, but may be plate-shaped.

[0007] Preferably, the arrangement of the rolling rollers 10 is devised so that the rolling of the china clay ingot 6 can be carried out evenly. That is, for example, the rolling rollers 10a to 10g are mounted so that the mounting positions of the rolling rollers 10a to 10g with respect to the roller supporting arm 9 are not symmetrical about the rotation axis of the wheel base 3. (See FIG. 2). In such a case, as shown in FIG. 3, the central portion is rolled by the rolling roller 10a closest to the axis, and then by the rolling roller 10b closest to the axis, by the rolling roller 10a. The outside of the rolled portion is rolled, and the outside is sequentially rolled by the subsequent rolling rollers 10c to 10g, so that rolling unevenness does not occur.

FIG. 5 shows another method for eliminating the uneven rolling.
As shown in (A), the roller supporting arms 9, 9a are formed in a cross shape, and the rolled portion of one of the rolling rollers toward the roller supporting arm 9 and the other roller. It is also conceivable to attach each rolling roller by changing the distance from the intersection of both arms so that the rolling portion of the rolling roller of the supporting arm 9a is different from that of the rolling roller. .

FIG. 5 (B) shows the same concept as that shown in FIG. 5 (A), and instead of assembling the roller support arms in a cross shape, a rolling roller is formed on the disk 11. A line is to be attached. In addition, as shown in FIG. 5 (C), the rolling rollers may be provided only for the radius of the rotating plate 4 by narrowing the mounting intervals of the rolling rollers.

The roller support arm 9 can change the mounting height of the standing plate 2 if necessary, and can rotate upward from a horizontal state. The reason why the mounting height can be changed is that the finished thickness of the pottery chunk 6 can be adjusted.
In addition, the reason why the wheel can be pivoted upward is to prevent use of the potter's wheel base 3 in its original usage so as not to disturb the work.

The method of enabling the mounting height of the roller support arm 9 to be changed is arbitrary. For example, a method in which a plurality of mounting holes 14 are formed in the upright plate 2 in the vertical direction and a nut is fixed thereto can be adopted. 1 and 2). Means for enabling the upward rotation can be arbitrarily used, for example, a hinge 15 can be used. 12 is an adjusting rod attached to the tip of the roller supporting arm 9;
The roller support arm 9 can be moved up and down, and
It is arranged at a position where it comes into contact with the edge of the rotating plate 4, and thereby adjusts the rolling thickness of the clay chunk 6.

FIG. 3 shows another example of the configuration for adjusting the rolling thickness. The roller supporting arm 9 has a T-shape at the center of a rotating member 13 provided on the upright plate 2. Attach to One end of the rotating member 13 is pivotally connected to the standing plate 2 and the other end is vertically movable in an arc shape. The vertical movement of the rotating member 13 adjusts the distance between the rolling roller 10 and the rotating plate 4.

When using the above apparatus, after adjusting the rolling thickness in advance, the china clay mass 6 is placed on the rotating plate 4 with the mats 7 and 8 interposed therebetween. Then, the roller support arm 9 is lowered, and the rolling roller 10 is brought into contact with the upper mat 8,
A weight w is applied to the tip of the roller support arm 9 by weight or the like as appropriate. Instead of applying a weight, a rubber ring having a lower portion hooked to the base 1 or the like may be applied.

When the wheel 3 is rotated in this way, the pottery chunk 6 is gradually spread and disc-shaped by the pressing force of the rolling roller 10 given by the weight and the centrifugal force due to the rotation. At this time, the mats 7, 8 are prevented from jumping out due to the centrifugal force due to the action of the stopper 5. When the stopper 5 is not provided, the mats 7 and 8 can be prevented from jumping out by means of, for example, providing a hooking portion between the rotating plate 4 and the mat 8 to hang a rubber band.

[0015]

As described above, the present invention has a simple structure, requires no installation space, is easy to maintain, can be provided at a low price, and can perform an efficient rolling operation. There is an effect that a good-quality rattle that cannot be obtained can be quickly obtained, and a round rattle can be formed.
