Description

Detailed description of the invention

この発明は、粉体のふるい機に関するものである。 The present invention relates to a powder sieving machine.

従来、穀物粉等のふるい機は穀物等を入れたふるいを前後に揺する方式、または軸を中心に回転させるものであった。 Conventionally, a sieving machine for cereal flour or the like has been a method of shaking a sieve containing cereals back and forth, or rotating around a shaft.

従来の穀物粉等のふるい機は前後に揺する方式、または軸を中心に回転させる方式のため、ふるい作業の際に穀物粉等が飛散する欠点があった。前後に揺する方式の場合は穀物粉等の往復移動の反転の際に粉が飛散する。軸を中心に回転させる方式の場合は回転円の接線方向へ穀物粉等が飛散する。 Conventional sieving machines for cereal flour and the like have a drawback in that cereal flour and the like are scattered during the sieving operation because they are swayed back and forth or rotated around an axis. In the case of swinging back and forth, the powder scatters when reversing the reciprocating movement of the grain powder or the like. In the case of the method of rotating around the axis, grain flour or the like is scattered in the tangential direction of the rotating circle.

本発明はこの問題点を解決するため、円状のふるいを取り付けるふるい機の円状のふるい揺動部の円の中心から離れた部分に電動モーターにカムを取り付けて、これを取り付け、このカム取り付け位置から約１２０度振った位置に、横に揺れるクランクを取り付け、更に１２０度振った位置に水平方向に自在可動な上下方向を支持する可動支持軸を取り付ける。その結果、円状のふるい揺動部は往復運動と円運動とが同時に進行する動きとなる。 In order to solve this problem, the present invention attaches a cam to the electric motor at a portion away from the center of the circle of the circular sieve swinging portion of the sieve machine to which the circular sieve is attached. A laterally swinging crank is attached to a position that is swung about 120 degrees from the attachment position, and a movable support shaft that supports a vertically movable direction that is freely movable in the horizontal direction is attached to a position that is further swung 120 degrees. As a result, the circular sieve oscillating portion has a motion in which the reciprocating motion and the circular motion proceed simultaneously.

本発明は以上のような構成であるので、穀物粉等を入れたふるいは往復運動と円運動とが同時に進行する動きになる。その作用効果により、穀物粉等はふるいの外に飛散することなく、ふるい作業が進行する。この効果を詳述すると次のようになる。すなわち、ふるい揺動部の円の中心から離れた部分に取り付けたカムによってふるいは円周部分の可動取り付け部分を中心にして楕円方向に力が作用する。このカムの取り付け位置に対して約１２０度振れた位置に横に揺れるクランクを取り付けることによって、横に揺れる方向に力が作用する。このカムとクランクの両者の協同作用により、往復運動と円運動が同時に進行する動きとなる。このような構成により、ふるいを揺動した際のふるいの或る一点について、運動の軌跡を解析したものが図４である。この軌跡上では円の接線方向へ飛散することがなく、内へ内へとコントロール出来る軌跡となっている。対象とする粉体は、穀物紛、茶粉、コーヒー粉、ココア粉、果実粉、乾燥野菜粉、乾燥魚粉、乾燥肉粉、生薬粉、薬剤粉、セメント粉等の無機物粉等である。本発明の構成による蕎麦粉のふるい機を製作し、試験を行ったところ、蕎麦粉は全く飛散せず、従来のふるい機に較べて顕著な効果を確認する事が出来た。更に蕎麦粉がふるいの外周に溜まらず、ふるい中央も含めて広がるため、従来方式に較べてふるいの所要時間が約２０％以上短縮する効果が得られた。 Since the present invention is configured as described above, a sieve containing grain flour or the like has a motion in which a reciprocating motion and a circular motion proceed simultaneously. Due to the function and effect, the sieving work proceeds without scattering the grain flour or the like outside the sieve. This effect is described in detail as follows. That is, a force is applied in the elliptical direction around the movable attachment portion of the circumferential portion by the cam attached to the portion of the sieve swinging portion away from the center of the circle. By attaching a laterally swinging crank to a position swung about 120 degrees with respect to the cam mounting position, a force acts in the laterally swinging direction. Due to the cooperative action of both the cam and the crank, the reciprocating motion and the circular motion are simultaneously advanced. FIG. 4 shows an analysis of the movement trajectory of a certain point of the sieve when the sieve is swung with such a configuration. On this trajectory, the trajectory can be controlled inward without scattering in the tangential direction of the circle. The target powders are inorganic powders such as cereal powder, tea powder, coffee powder, cocoa powder, fruit powder, dried vegetable powder, dried fish powder, dried meat powder, herbal medicine powder, drug powder, and cement powder. A buckwheat flour sieving machine according to the configuration of the present invention was manufactured and tested. As a result, the buckwheat flour was not scattered at all, and a remarkable effect was confirmed as compared with the conventional sieving machine. Furthermore, since the buckwheat flour does not collect on the outer periphery of the sieve and spreads including the center of the sieve, the effect of shortening the required time for the sieve by about 20% or more as compared with the conventional method was obtained.
