Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for manufacturing containers that can be formed into bottomed containers with arbitrary cross-sectional shapes by extruding clay using extrusion molding means.

(Conventional Technique 1! FI) Conventionally, most bottomed containers such as vases were manufactured using a slurry molding method, and among these, those using the slurry casting method were made using the moisture in the slurry to form the plaster mold. The vine can be absorbed into any shape with a trunk wall and bottom wall of the required thickness,
It takes a long time to form this, resulting in low productivity.Also, although the plaster molds are dried and used repeatedly, the relatively small number of molds produced makes them unable to absorb water, and new ones must be used. In addition, in the case of the solid cast molding method, the shape of the inner and outer walls can be made into almost any shape, or it is difficult to remove the core, and special molds are required for both methods. .

In addition, some were manufactured using the potter's wheel molding method,
Although it is possible to make the side surface shape arbitrary, all of them are in the shape of a rotating body, so the cross-sectional shape is circular.

Recently, there has been research into manufacturing it using extrusion molding, but conventionally it has generally been the manufacture of solid objects such as roof tiles and roof tiles, while hollow objects have been manufactured with circular or polygonal shaped cross sections. Only clay pipes and the like made of such materials have been manufactured, and no method has yet been developed to easily manufacture bottomed container-like items that have a modified body and do not leak water.

(Problems to be Solved by the Invention) Therefore, the present invention aims to solve the above-mentioned problems by using the conventional molding method using slurry, which takes a long time and has low productivity, and which limits the number of times the plaster mold can be used repeatedly. It is difficult to remove the shell, the potter's wheel molding method can only produce products with a circular cross-section, and furthermore, the extrusion molding method makes it difficult to change the body material, making it difficult to produce products that do not leak. The object of the present invention is to create a manufacturing method for easily manufacturing containers with arbitrary cross-sectional shapes and leak-proof bottoms by extrusion molding.

(Means for Solving the Problems) That is, the first aspect of the present invention is to extrude clay using an extrusion molding means to form a hollow body-like trunk material having an arbitrary cross-sectional shape and an arbitrary length with at least one end being a smooth surface. Furthermore, a bottom wall material having at least one flat surface made of the same material as the body material is formed, and a slurry of clay made of the same material as the bottom wall material and the body material is formed before each of them dries. After interposing the resulting material between the smooth surfaces of the bottom wall material and the body material and pasting them together, the outer periphery of the bottom wall material is processed as appropriate to form a container material, and this is then There is a method for manufacturing containers that can be dried and baked in an appropriate cross-sectional shape and have a bottom, and the second invention is to extrude clay using an extrusion molding means to form containers with an arbitrary cross-sectional shape and a smooth surface at least one end. A hollow body-like trunk material of arbitrary length is formed, and the outer surface of this material is processed appropriately, and a bottom wall material is made of the same material as the trunk material and has at least one smooth surface. The clay of the same material as the bottom wall material and the body material is made into a slurry and then interposed between the smooth surfaces of the bottom wall material and the body material and pasted together before they dry. Dress up, and
Process the outer periphery of the bottom wall material as appropriate to form the container material,
There is a method for manufacturing a container which can be formed into a container having an arbitrary cross-sectional shape and a bottom by drying the clay and firing it appropriately, and the third invention is to extrude the clay using an extrusion molding means to form a container having an arbitrary cross-sectional shape and smoothing at least one end. A hollow body-like trunk material of arbitrary length with a flat surface is formed, and a bottom wall material with at least one smooth surface is formed from the trunk material and the trunk material, and the bottom wall material is formed into a flat surface before each of them dries. A slurry made of the same clay as the wall material and the body material is interposed between the smooth surfaces of the bottom wall material and the body material and adhered together, and after drying, the outer surface etc. This is a manufacturing method in which the material is appropriately processed and fired.

(Function) A method for manufacturing containers that can be formed into any shape with a bottom according to the present invention by the above-mentioned means (hereinafter referred to simply as a single-ring manufacturing method)
In the first invention, the clay supplied from the hopper of the extrusion molding machine is kneaded in a part of the auger and is forced forward, and is shaped into a cross-sectional shape according to the gap between the arbitrarily shaped mouth mold and the core. When the desired length is reached, part of the auger is stopped and the cut is cut with a smooth and right-angled surface at the internuclear die exit. Continuing to operate part of the auger, cut the cut so that it has a smooth surface and a non-perpendicular surface.A hollow body with an arbitrary cross section and an arbitrary length with smooth surfaces at both ends is cut. A shaped body material is formed. In order to make at least one end a smooth surface, the above-mentioned cutting may be performed by cutting into two arbitrary lengths and then dividing into two by appropriate means.

On the other hand, the bottom wall material may be made of the same material as the body material, have at least one flat or smooth surface, and have the same cross-sectional shape or larger diameter as the body material, and the other surface may be a non-smooth surface. In addition, since the thickness may be unequal, it is sufficient to form it separately using a simple press molding machine, etc., and place it on a table with the smooth side facing upward, and then apply the same material to the smooth surface of the body material. A slurry of clay is attached, and it is inserted in an upright manner onto the upward facing bottom wall material and adhered as one piece, and the outer periphery of the bottom wall material is processed as appropriate. Since it is dried, glazed, colored, etc. as appropriate, and then fired, it is reliably integrated and has no cracks, so it can have any cross-sectional shape without water leakage, and the shape of the upper opening can also be changed. The bottom container is molded.

In addition, in the second invention, after suitably processing the outer surface etc. of the body material formed in the same manner as in the first invention by cutting etc., the bottom wall material is attached in the same manner as in the first invention. Since the material is processed and fired, in addition to the first invention, striped patterns, etc., which cannot be obtained by extrusion molding, can be exposed on the outer surface of the body.

Further, in the third invention, the bottom wall material is integrally attached to the body material in the same manner as the first invention, and after drying, the outer surface etc. of this are processed by gluing etc. as appropriate. The IJ was fired as appropriate, and by gluing after drying, a pattern, etc., which was slightly different from that of the second invention, was exposed on a part of the outer surface of the IJ.

FIG. 1 shows the manufacturing method, and clay P is supplied from hopper H of an extrusion molding machine. is kneaded in part A of the auger and is forced forward (diagonally downward left in the figure), and is then passed through a gap between a mouth shape of an arbitrary shape and a core (not shown) into a continuous hollow shape having a cross-sectional shape according to this shape. When it is extruded and reaches a desired length, the extrusion operation of the auger part A is temporarily stopped, and the body material 11 is cut by a cutter C at the outlet of the mouth molding, and the body material 11 is sent out onto the delivery path Bl. Ru.

In addition, the bottom wall material 12, which is made of the same material and has a rectangular shape with a larger diameter than the cross-sectional shape of the body material 11 by pressing or the like, is placed on the other delivery route B2 with the smooth surface 121 facing upward. The body material 11 and the bottom wall are bonded together with the body material 11 to which the adhesive member 13 made of clay, which is the same material as the body material 11, has been appropriately adhered. The container material 12 is integrated with the component material 12, and the excess portion 123 extending to the outer periphery is cut off to form the container material 1.

In addition, in this example, we will explain examples manufactured by each manufacturing method of each invention, and for all the smooth surface shapes of the body materials, we temporarily stopped the extrusion operation of a part of the auger and used a mouth mold outlet in the longitudinal direction. In addition, the bottom wall has the same thickness at all edges and is smooth on both sides except for the legs, but these are the same as those obtained in the first invention. The outer surface of the body material may be processed by cutting or the like according to the second invention, and then fitted according to the third invention.

Cutting to form the body material may be done without operating part of the auger, and the bottom wall may be cut on a smooth surface or non-perpendicular to the length direction, and the bottom wall may also be cut with uneven thickness and the other surface may be uneven. These changes may be arbitrarily determined within the scope of achieving the objectives and effects of the present invention described above and the effects of the invention described below, and these changes do not change the gist of the present invention in any way. Needless to say.

(Effects of the Invention) As described in detail above, the present invention continuously extrudes clay from an extrusion molding machine as a hollow body with an arbitrary cross section, and cuts the clay into an arbitrary length so that at least one end has a smooth surface. The body part material formed by the process is integrated with a bottom wall part material formed of the same material as the body part material with at least one side having a smooth surface, with an adhesive member made of the same material in the form of a slurry interposed, and this is processed as appropriate. Because it is dried, processed, etc. as appropriate, and fired, the composition is reliably integrated, and there are no cracks or the like during firing, so there is no water leakage. Furthermore, the cross-sectional shape, the cut surface of the upper end of the trunk material, the side shape of the trunk, the size and back surface shape of the bottom wall material, etc. can be made into any desired shape, and it is easy to obtain a variety of trunk materials. In addition, it is a truly excellent invention in practical terms, as it is not limited by plaster molds and has high productivity.
