Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotary switching valve intended for improving the finished condition of a commodity and decreasing the proportion defective of a commodity through solving such a problem that a confectionery material is extracted to a mold in a half-liquid state with a device which sends the half-liquid confectionery material from a feeding device [corresponding to No.6 figure (not shown)] through a rotary valve (corresponding to 15) to a mold (35) for a commodity, and it is more effective that the half-liquid confectionery material has higher pressure so as to prevail to all over the commodity, but as the confectionery material overflows from an engaging part of a valve at the time of molding the commodity in the process, the finished condition of the commodity is not desirable. <P>SOLUTION: Two cylindrical rotary switching valves (5 and 15) opposed to each other are used on a valve body (36) in a switching valve device (30) as illustrated No.2 figure (not shown). The switching device is constructed with a material pressure device (40) which arbitrarily and easily adjusts strokes (St) of a piston (21) of a cylinder (20) at the time of sending pressed half-liquid confectionery material to the mold (35). As a result, the half-liquid solid confectionery material can be easily sent to a commodity molding device (50). <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

この発明は、半液状体の菓子材を製品用の成形型（３５）に送込む供給配管の途中に設けた切換弁に関するものである。 The present invention relates to a switching valve provided in the middle of a supply pipe for feeding a semi-liquid confectionery material to a product mold (35).

従来は、送込み装置（５５に相当）から送り込まれた菓子材を「ロータリ弁」を経由して製品用の成形型に送り込むもの。（例えば、非特許文献１参照）
また、高温の気体の切換弁として筒形タイプのものがある。（例えば、特許文献１参照）Conventionally, a confectionery material fed from a feeding device (corresponding to 55) is fed into a product mold through a "rotary valve". (For example, see Non-Patent Document 1)
There is also a cylindrical type as a high-temperature gas switching valve. (For example, see Patent Document 1)

Problems to be solved by the invention

半液状体の菓子材を製品用の成形型の端部に抽出する為には、液状圧が高い方が隅々までゆきわたり良い。
尚、液状圧が高くなると切換弁の隙間部よりリーク（洩れ）が多くなる。これらの相反することを兼ね備えた簡単な機構で耐久性の弁装置が望まれていた。
また、菓子材の混成練装置（５５）が余り複雑にならなく簡単な装置にて液状圧が任意の高い圧力にできる方式が望まれていた。In order to extract the semi-liquid confectionery material to the end of the product mold, the higher the liquid pressure, the better.
In addition, when the liquid pressure increases, leakage (leakage) increases from the gap of the switching valve. There has been a demand for a durable valve device with a simple mechanism having both of these contradictions.
In addition, there has been a demand for a method in which the confectionery material mixing and kneading apparatus (55) is not so complicated and the liquid pressure can be arbitrarily increased with a simple apparatus.
