Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a container used in the production of ceramics having a neck portion.

[Conventional technology]

Conventionally, as shown in Figure 8, as a manufacturing method for ceramics in which an elongated neck part is formed in the middle part of the vessel, such as a wine glass, the elongated neck part c
After forming a base material a consisting of a container body b, which will become a product after firing, and a hanging base part e, which is integrally provided in a container shape around its base part d and has holes f, f, the base material a is A method of drying and solidifying the material, and then firing it while supporting it by inserting hanging rods g through the holes f, or, as shown in Fig. 9, a container having an elongated neck part c and used as a product after firing. A hanging ring part i protruding in the axial direction from the center of the main body b and its base part d.
After molding a base material a consisting of the above, a hanging rod g is inserted into a hole in a hanging ring part i of the base material a, and the molded base material a is suspended while firing.

However, in the former method, when cutting the hanging table part e along the boundary with the base part d with a diamond cutting machine after firing to obtain a product,
There is a problem in that the yield is poor because it is difficult to hold the substrate a vertically with the hanging rod g until after firing, and in the latter method, the hanging ring part i is removed from the semi-finished product after firing. When cutting at the end k, there was a drawback that the cut trace remained dirty.

In order to eliminate this conventional drawback, JP-A-59-
Publication No. 210295 discloses a method in which a base body consisting of a container body having a neck portion and a thin-walled hanging base portion integrally provided at the base of the container body is formed, and this hanging base portion is formed into a divisible annular support. A method is disclosed in which the material is dried, solidified, and fired in a suspended and supported state.

This has the advantage that since it is dried and fired in a suspended state, it will not bend even if the neck portion becomes quite long, and that a firing kiln of no special structure is required.

[Problem that the invention seeks to solve]

However, in the case of products using the hanging method for ceramics that have a neck part, each molded product is suspended, which takes up space in the kiln, and the hanging process is troublesome and inefficient. There is a drawback.

An object of the present invention is to dry or fire a molded base consisting of a container body having a neck portion and a hanging platform integrally provided at the base of the container body.
The objective is to provide a container that increases processing efficiency.

[Means for solving problems]

The present invention relates to a hanging container used when drying or firing a molded material, which comprises a container body having a neck portion and a flange formed at the end of a hanging stand portion integrally provided at the base of the container body, which comprises: It is characterized by comprising a cylindrical body for suspending and accommodating a molded base, the upper part of which is formed with a small-diameter stepped portion for suspending the molded base by placing a flange formed at the end of the suspension platform for the molded base. do.

[Effect]

The molded blanks, which are suspended while being supported by flanges formed at the ends of the suspension bases, are accommodated within the cylindrical body and can therefore be freely placed within the kiln without requiring any special effort.

〔Example〕

An example in which the hanging storage device of the present invention is used for baking will be explained below.

As shown in FIG. 1, the base 1 consists of a container body 2 having a neck portion 3 and a hanging base portion 5 integrally provided around the base 4 of the container body 2. A flange portion 6 is formed at the outer peripheral end of the hanging table portion 5 . The hanging platform 5 provided on the base 4 of the container body 2 is formed thin so that it can be easily cut with a diamond cutting machine after the base 1 is fired.

When drying after forming, as shown in FIGS. 2 and 5, a hanging plate 7 provided with a notch 8 that locks the base material 1 at the neck section 3 is used, and the substrate 1 is hung from the neck section 3 for drying. let

At this time, tension due to the weight of the suspended portion of the substrate 1 acts on the neck portion 3, but since the tension acts in the axial direction of the substrate 1 and the lightweight container portion is below, the net The portion 3 is less likely to be stretched or bent or distorted. This is network part 3
Since the tension acting on the base 1 is small and no load from the base 4 and the hanging base 5 acts on the neck 3, the yield of the base material 1 used in the firing process is high.

When using the base suspension board 7 for drying, it is preferably made of gypsum, which has low hardness, high specific gravity, and water absorption. By using this hanging plate 7, the substrate 1, which is soft and easily distorted immediately after forming, is hung and dried without damaging the locked portion of the neck portion 3. After drying, the substrate 1 is transferred to a conveyor 9, for example. It is extremely easy to work as it is transported to the next process while suspended.

Of course, instead of this hanging plate 7, a storage container 10 shown in FIG. 3 can be used.

FIG. 3 shows a cylindrical hanging container (cylindrical top) 10 according to the present invention. In this example, a cylindrical hanging container is used for firing.

As shown in the figure, the cylindrical storage container (cylindrical boss) 10 has a cup of a main body 2 of a shaped bisque 1, in order to place a flange 6 formed at the end of a hanging base 5 on the upper part. A small-diameter stepped portion 11 having a diameter larger than that of the flange portion 6 is formed at the upper part of the inner wall, and the height of the rising portion of the inner wall of the stepped portion 10 is formed higher than the thickness of the flange portion 6.

In order to store the molding material 3, the molding material 3 is turned upside down, inserted upside down from above, and the flange portion 6 is placed on the stepped portion 10 and suspended.

Then, the containers 10 shown in FIG. 6 in which the molding materials 3 are suspended and stored are stacked in several tiers as shown in FIG. 7, placed in a firing kiln, and fired.

In this way, there are many cylindrical storage containers 1 inside the kiln.
A large number of containers 0 are arranged in a straight line without taking up much space, and the substrates 1 are fired while being suspended in each container.

At this time, even if the base material 1 whose neck portion 3 is somewhat bent in the drying process is used, the base material 1 will not remain in each container 10.
is suspended almost vertically, so the net part 3
Most of the curvature is straightened during firing. Therefore, after firing, a large number of semi-finished products such as the neck portion 3 with less distortion can be obtained.

As shown in FIG. 4, the fired semi-finished product thus obtained is cut out by cutting off the flange part 6 using a diamond cutting machine to produce a ceramic piece having a neck part.
You can complete it to 2.

〔Effect of the invention〕

The present invention provides the following effects.

(1) It is easy to hang and store the base formed by a container body having a neck portion and a hanging stand portion having a flange portion.

(2) Since the molded substrates are stored in a cylindrical container, they can be stacked and arranged in a stacked manner without requiring any special effort when charging into a drying kiln or firing kiln, increasing processing capacity.

(3) During drying and firing, the molded base is suspended with the base facing up, so that the bending of the neck portion is corrected during kiln processing, improving product yield.
