A recess 51 into which the bottom of the processed article 7 is fitted
a is provided, and the permanent magnet 31 is provided at the center of the recess 51a.
Permanent magnet insertion hole 51b having a diameter approximately the same as or slightly larger than the outer diameter of
Has been drilled. That is, when the front enamel processed product 7 is fitted in the recess 51a, the center of the front enamel processed product 7 is substantially aligned with the center of the permanent magnet insertion hole 51b. Further, on the lower surface of the glaze coating material supporting portion 51,
Four screw holes 51c into which the support bolts 59 are screwed are radially provided.

The shaft member supporting portion 52 is the shaft body 3 of the shaft member 3.
2 is provided with a shaft main body support hole 52a into which
The screw holes 52b of the support bolts 59 of the glaze coated material supporting portion 51 are formed so as to surround the shaft body supporting holes 52a.
It is provided at a position corresponding to c. Also, the screw hole 52
b are provided at a plurality of different positions in the radial direction from the center of the shaft member supporting portion 52 so that the glaze coated material supporting portions 51 having different sizes can be supported. In the glaze coating material support portion 51, one end of the support bolt 59 is provided with the screw hole 5
1c is screwed to the other end, and the other end is a screw hole 52 of the shaft member supporting portion 52.
The shaft member support portion 52 is supported by the support bolt 59 on the shaft member support portion 52 by being screwed into the shaft b, and the length of the support bolt 59 screwed into the screw holes 51c and 52b is adjusted. The distance between the glaze coating material supporting portion 51 and the glaze coating material supporting portion 51 can be adjusted.

The glaze coating apparatus 1 is constructed as described above. First, as shown in FIG. 3, the shaft body 32 of the shaft member 3 is inserted into the shaft body supporting hole 52a of the shaft member supporting portion 52, and the shaft body 32 is inserted. The main body 32 is supported in an upright state, and the screw holes 51c or the screw holes 52b of the support bolt 59 are supported.
The degree of screwing in is adjusted so that the tip surface of the permanent magnet 31 and the bottom surface of the recess 51a are substantially flush with each other. Next, as shown by a chain line in FIG. 3, the front enamel processing object 7 is placed on the glaze-coated material supporting portion 51 of the shaft member mounting auxiliary jig 5 so that the bottom 71 thereof can be received by the bottom of the recess 51a. .

By placing the front enamel processed product 7 in the recess 51a, the central axis of the shaft main body 32 and the front enamel processed product 7 are placed.
And the permanent magnet 31 is attracted to the bottom 71 of the front enamel processing object 7. Then, the front enamel processed product 7 in which the shaft member 3 is integrated by the attraction of the permanent magnet 31 on the bottom is pulled up from the shaft member mounting auxiliary jig 5, and FIG.
As shown in FIG. 5, the bearing 33 of the shaft member 3 is fitted into the groove portion 41 of the bearing member 4, and the opening 7 of the front enamel processing object 7 is opened.
(2) The peripheral edge is received by the upper surface of one of the rollers 22, and at the same time, the drive motor 23 is driven to rotate the roller 22, and the front enamel processing object 7 is driven by the roller 22 to rotate about the central axis of the shaft body 32. Then, the glaze 6 attached to the surface of the roller 22 is applied to the periphery of the opening 72.

That is, this glaze coating apparatus is configured as described above and has the following excellent effects. (1) The front enamel processed product 7 is adhered to the surface of the roller 22 while the peripheral edge of the opening 72 of the front enamel processed product 7 is received by the upper surface of the roller and the front enamel processed product 7 is driven around the central axis of the opening 72 by the rotational driving of the roller 22. Since the glaze 6 is applied to the peripheral edge of the opening 72, even an inexperienced operator can surely apply the glaze 6 to the peripheral edge of the opening 72 with a uniform width.

(2) Since the attracting means is the permanent magnet 31, the shaft member 3 can be easily attached to the front enamel 7 by the attraction force of the permanent magnet 31. Since the shaft member mounting auxiliary jig 5 is provided, the shaft member 3 can be easily placed in a state where the central axis of the shaft main body 32 thereof substantially coincides with the central axis of the opening 72 of the front enamel processed product 7. 71 can be attached. (3) Since the shaft member mounting auxiliary jig 5 is composed of the glaze coating material supporting portion 51, the shaft member supporting portion 52, and the four support bolts 59, the glaze coating material supporting portion 5
1 for other glaze-coated material supporting portions 51 having different recesses 51a
By doing so, even if the shape of the front enamel processed product 7 is different, the shaft member 3 can be easily brought into a state in which the central axis of the shaft main body 32 thereof substantially coincides with the central axis of the opening 72 of the front enamel processed product 7. It can be attached to the bottom 71 of 7.

(4) Since the glaze coating device main body 2 is provided with the two rollers 2 and 22, the glaze is simultaneously applied to the two glaze coating materials, or the material main body portion of the glaze coating material is divided into two. If it is set so as to straddle the rollers 2 and 22 of the book, it is possible to apply the glaze in a stable state even with a large material to be applied with the glaze.

The present invention is not limited to the above embodiment. In the above-mentioned embodiment, the material to be coated with glaze is the pre-enabling material, but it may be pottery or porcelain.
When the material to be coated with glaze is a non-magnetic material such as pottery, porcelain, or stainless steel, the adsorption means is
For example, a suction cup or a double-sided adhesive can be used. In the above-mentioned embodiment, the opening is a substantially perfect circle, but it may have a shape in which a small projecting portion serving as a spout is provided in the radial direction of the opening. If the opening is substantially circular,
The center axis of the bottom and the center axis of the opening may be displaced from each other.

[0025]

Since the glaze coating method and the glaze coating apparatus according to the present invention are configured as described above, anyone can easily and accurately apply the glaze for edging stably at a predetermined position. can do.

In particular, according to the glaze coating device of the third aspect, the shaft member can be easily attached to the glaze coating material by the attractive force of the permanent magnet. Further, according to the glaze coating device of claim 4, the shaft member is easily made to be the glaze coating material in a state where the central axis of the shaft body coincides with the central axis of the opening of the material body. Can be installed.
