Description

【０００１】
【発明の属する技術分野】
本発明は篩装置に関し、特に振動発生装置により発生させた振動を直接篩網に伝達可能で効率よい篩いを実現可能であり、篩網の着脱が容易な篩装置に関する。
【０００２】
【従来の技術】
従来の篩装置、即ち電磁石、エアー等によるピストンの振動或いはモーター、超音波発振器等により篩に振動を与え小麦粉等の粉状物や粒状物等の粉粒体等をふるう篩装置としては、特開２００１−１２９４８３、特開２０００−１３５４７４、特開平１１−３１２８６０、特開平１１−１２８８４２、特開平１０−７６２２９、特開平９−１４１２０５に開示されている篩装置がある。
【０００３】
これらの篩装置には装置の下部に振動を発生させる振動発生装置を設置し、上部に篩網を有する有底体を設置して篩われた粉粒体等を装置外部に排出する機構を設けたものがある。このような篩装置では、篩に掛けられた粉粒体等は一度第一の集積部即ち有底体底部に落下し、第一の集積部上を摺動し第二の集積部例えば収集容器に異動して収集されるためその間に篩われた粉粒体が凝集、団塊状になり、篩にかける意味が減殺されてしまっていた。
【０００４】
又、粉粒体は装置外部に排出されるので、装置自体の小型化がなされていても、その使用に際しては装置の脇に排出された粉粒体等を受ける容器等の設置場所を必要とし、広い設置場所を必要としていた。更には、粉粒体等の容器からの漏脱や粉煙が辺りに散る事が避けられなかった。従って、限られた広さで、しかも清潔な環境が要求される厨房等での使用には不向きであった。
【０００５】
又、篩網上に残留した粉粒体等を除去する機構、装置を設けたものがあるが、該機構、装置の設置により装置全体として大型になることが不可避であり、広い設置場所を必要とし、限られた狭い広さでの使用には不向きであった。
【０００６】
又、これらの篩装置は装置下部の振動発生装置で発生させた振動を複数のスプリングにて支持された篩網に伝達させているので、スプリング相互の揺れの差異により振動が篩網全体に効率よく伝わらず、又、スプリングに振動が吸収されてしまい、ふるい分けの速さが遅く、効率がよくなかった。又、このような構成にて篩の効率を求めた場合には動力源たる振動発生装置が大型化していた。
【０００７】
又、篩網の側部に振動発生装置を設置し篩網を有する機構に直接振動を与えるものもあるが、篩網を有する機構の一端からのみ振動を与えていると共に篩網を有する機構を連結材に吊るして設置しているために振動が連結材に抑制され、同様に振動が篩網全体に効率よく伝わらず、ふるい分けの速さが遅く、効率がよくなかった。
【０００８】
更に、上記装置中篩網或いは篩網を有する機構が装置に固定され、或いは容易には着脱不可能な構成となっている篩装置或いは篩網を有する機構が大型である篩装置は、篩網上に残留した粉粒体等の除去、篩網の洗浄、設置等が容易ではなかった。又、篩網上に残留した粉粒体等を除去する機構、装置を設けた装置にあっては篩網の洗浄、設置等の為には該機構の着脱が必要であり、篩網上に残留した粉粒体等の除去は容易となっても篩網の洗浄、設置等が更に困難となっていた。
【０００９】
又、篩網の側部に振動発生装置を設置し篩網を有する機構に直接振動を与える装置では篩網上に残留した粉粒体等の除去、篩網の洗浄、設置のために篩網、分散羽根を有する機構及び該機構を支持する連結部材の分解、着脱が必要であり、篩網上に残留した粉粒体等の除去、篩網の洗浄、設置は煩雑であった。
【００１０】
又、モーターやピストンを使用した場合にはかなりの騒音を発し、更にこれらの振動発生装置が直接篩装置に設置されているために篩装置自体の振動を充分に抑えることが出来なかった。又、これらの振動発生装置は振動や粉粒体等によって故障しやすく、メンテナンスが容易ではなかった。
【００１１】
【発明が解決しようとする課題】
本願発明は上記のような従来技術の欠点を解消するため、篩い後の粉粒体等の飛散を防止し、狭く、清潔な環境が要求される場所での設置、使用が可能であると共に、小さな動力源で振動が篩網全体に効率よく伝わり、速く、効率の良い篩いが可能であって、篩い後の粉粒体等の凝集、団塊状化を防止し、更には、篩網への充分な振動の伝達が可能であると共に、篩網上に残留した粉粒体等の除去及び篩網の洗浄を容易とするために篩網の着脱が容易であり、騒音及び装置自体の振動を抑えられると共に清掃、メンテナンスが容易な篩装置を提供することを目的とする。
【００１２】

【００１４】
第二の手段は、第一の手段において更に対向する二体の振動体を連結材にて連結固定したことを特徴とする篩装置である。
【００１５】
この第二の手段によれば振動の相乗効果が発生し、小さな動力源で済むと共に、より効果的な振動が得られ振動が篩網全体に効率よく伝わり、更に速く、効率の良い篩いが可能となった。
【００１６】
第三の手段は第一又は第二の手段において二体の振動体の夫々には、対向側面に凹部を有する結合部を形成し、該対向する凹部に篩網両側端部を挿通自在にしたことを特徴とする篩装置である。
【００１７】

【００１８】
第四の手段は、第三の手段において振動体は支持体に支持された基体と基体から突設した伝振体と該伝振体先端部に固着された結合部から構成され、枠体中部両側部に内側面に孔を有する中空部を形成し、該中空部に振動発生装置及び振動体を収納すると共に、孔から伝振体を突出させ、両側面から突出した結合部に篩網を挿着することを特徴とする篩装置である。

【００２１】

【００２８】
【発明の実施の形態】
以下本発明の実施の形態を図に従って説明する。篩装置１は、枠体２、振動発生装置３、振動体４、連結材５、載置台８、振動吸収体１０、篩網１２で構成され、篩装置１の上部には供給器たる容器１３が、下部には受給器たる容器１４が設置されている。
【００２９】
枠体２は振動発生装置３、振動体４、連結材５、載置台８、振動吸収体１０及び篩網１２を被覆、設置し、粉粒体等を収納する容器１３，１４を設置する為のものであり、ステンレス等により形成する。枠体２の中部両側部には篩装置１の内側に張出した底面が水平の中空部２７，２７を形成し、該中空部２７に振動発生装置３、振動体４、載置台８、振動吸収体１０を設置する。枠体２の中空部２７部分の内側面２７２には振動体４を中空部２７から突出させるための孔２２を振動体４或いは伝振体４３の形状、数量に応じて適宜数、形状に形成する。
【００３０】
枠体２には脇窓２１，２１を篩装置１の中空部２７，２７の両外側面に形成し、該脇窓２１，２１部分には開閉自在の窓蓋２１２，２１２を設置することは推奨される。該脇窓２１により枠体２により形成される振動発生装置３、伝振体４、連結材５、載置台８及び振動吸収体１０が格納された中空部２７内の観察、メンテナンスが容易に可能となる。
【００３１】
枠体２の下部には粉粒体の受給器たる容器１４を出し入れ可能な受給器収納部２３を形成し、受給器収納部２３の上部に側面を中空部２７，２７に挟まれた篩網１２を設置する篩収納部２４を形成する。篩収納部２４は篩網１２を篩装置１前面よりスライドさせて設置可能なように前面部を篩網１２の縦断面以上の大きさに開口させて形成する。又、篩網収納部２４の該前面部には開閉自在な扉２５を設置すると共に、篩収納部２４の上部に蓋２６を設置することは推奨される。勿論蓋２６は粉粒体等を供給する容器１３の排出孔１３１からの粉粒体等の落下を妨げないような適宜幅に形成する。又、受給器収納部２３の前面にも受給器収納部２３を閉口する開閉自在の蓋を設置することは推奨される。
【００３２】
枠体２の上部両側部には中空部２７の上部に中空部２７と同一空間を構成する上空部２８，２８を設ける。中空部２７から上空部２８にかけて枠体２の内側面２７２は装置外側面方向に斜傾させ、篩収納部２４の上部であって、上空部２８，２８に挟まれた篩装置１の上部に粉粒体等の供給器たる容器１３を設置する供給器収納部２９を形成する。又、上空部２８の上面部には容器１３端部を載置し、容器１３を支持するための適宜幅を有する載置部２８１，２８１を形成する。更に、枠体２の中部背面部には中空部２７，２７を繋ぐ空間を形成し、該空間に連結材５を設置して中空部２７，２７に設置された振動体４，４を連結固定する。
【００３３】
このように枠体２は粉粒体等の供給器たる容器１３及び粉粒体の受給器たる容器１４を夫々供給器収納部２９、受給器収納部２３に収納設置することにより少なくても三方向から被覆すると共に、篩網１２を篩網収納部２４に収納することにより扉２５及び蓋２６と共に四方を被覆している。又、枠体２は振動発生装置３、振動体４、連結材５、載置台８、振動吸収体１０等の部材を中空部２７，２７及び中部背面部に形成した空間に収納することにより完全に被覆し、粉粒体等の供給器たる容器１３、粉粒体の受給器たる容器１４、篩網１２及びそれらの収納部である供給器収納部２９、受給器収納部２３及び篩網収納部２４と分離している。そして、このような構成にしたことにより粉粒体は篩装置１の外部に飛散することなく、且つ振動発生装置３、振動体４、連結材５、載置台８、振動吸収体１０等の部材に付着することがなく、篩装置の清掃、メンテナンスが容易となっている。
【００３４】
振動発生装置３は篩網１２を振動させる振動を発生させる為の装置であり、導線３１を介して電流が供給され、図示しない電源の入切を行うスイッチボタン及び電流の供給、遮断を連続的に行う回路機構によって制御されている電磁石である。振動発生装置３は篩網収納部２４の両側に形成されている中空部２７，２７の夫々に一体づつ計２体設置する。この両側に設置された振動発生装置３，３は同期振動させてもよいが、させなくてもよい。尚、振動発生装置３は電磁石に限定されることなく、モーターやエアー等によるピストン振動装置等を使用することとしてもよいことは勿論である。モーターを使用する場合には振動を伝達するカム等の振動伝達部材を設置する。又、振動発生装置３は枠体２の中部背面部の空間に一体設置し、連結材５に振動を与えて、連結材５が振動体４，４に振動を与えることにより篩網１２を振動させることとしてもよい。
【００３５】
振動体４は振動発生装置３で発生させた振動を得て振動し、篩網１２に該振動を伝達する為の部材であり、基体４１、受振体４２、伝振体４３及び結合部４４から構成されている。基体４１は適宜長を有する平板状或いは棒状等に形成し、その一端が篩装置１の背面空間部に位置するように中空部２７内に篩収納部２４に平行且つ水平に設置する。振動体４は載置台８の両前後端等にボルト等によって固定された支持体４７，４７上に載置されている。支持体４７は振動体４を載置可能な強度を有すると共に篩装置１の前面背面方向に遥振可能なステンレス等の薄板で形成されている。勿論支持体４７は篩装置１の前面背面方向に遥振可能且つ振動体４を載置可能な強度を有するものであれば棒状、柱状等の形状としてもよく、合成樹脂等にて形成してもよい。
【００３６】
基体４１は支持体４７，４７に固定することが望ましい。固定方法として基体４１に直接ボルトや溶接により支持体４７，４７を固定することとしてもよいが、基体４１下面に、支持体４７，４７の内側にボルト或いは溶接等により基体４１に固定した止具４９，４９に支持体４７，４７を溶接或いはボルト等により固定設置することは推奨される。止具４９は湾曲した支持体４７の戻り力に押圧されて振動体４を振動させると共に受振体４２を振動発生装置３たる電磁石から引き離し、更には基体４１が必要以上に揺振することを防止するためのものであり、基体４１の長辺間に渡って四角柱状等に形成する。
【００３７】
受振体４２は振動発生装置３で発生させた振動を直接受けて基体４１に伝達する部材であり、振動発生装置３たる電磁石に引きつけられることが可能な鉄等により適宜厚の方体等に形成し、基体４１の下面に溶接、ボルト等により固定し、振動発生装置３たる電磁石の磁界内であって振動発生装置３たる電磁石に電流が供給されていない際に電磁石から適宜距離に位置するように設置する。更に、受振体４２は振動発生装置３たる電磁石に電流が供給され、該電磁石にひきつけられた際にも電磁石に接触しないように、受振体４２を適宜位置に設置すると共に支持体４７に適宜の湾曲に対する強度を持たせることは推奨される。
【００３８】
伝振体４３は基体４１からの振動を結合部４４を介して篩網１２に伝達する板状または柱状等、望ましくは円柱状の部材であり、基体４１に溶接、ボルト等により固着し、枠体２の内側面２７２に形成した孔２２に挿通して設置する。伝振体４３は１の基体４１に対して２体以上設置することは推奨される。又、伝振体４３を柱状ではなく平板状に形成して１体以上を設置することとしてもよい。尚、枠体２に形成した孔２２には弾力性を有するゴムや合成樹脂等によって形成された中空状のパッキン７を設置して、伝振体４３の振動が妨げられることなく枠体２と伝振体４３の衝突を防止すると共に、粉状物の中空部２７への侵入を防止することは推奨される。
【００３９】
尚、伝振体４３を設けずに、基体４１に結合部４４を形成し、或いは基体４１に直接篩網１２を装着設置することとしてもよい。
【００４０】
結合部４４は篩網１２を設置し、振動体４と篩網１２を結合する為の部材であり、伝振体４３，４３に支持されている。結合部４４は合成樹脂、ステンレス等により断面コの字型の柱状体に形成し、このように形成された柱状体の凹部即ち溝４４１を篩網収納部２４方向に向けて枠体２正面から背面方向に水平に設置する。溝４４１は結合部４４の前面４４３に達するように形成するが、背面４４４には達しないように形成し、篩網１２の挿入多寡を防止し、適当な位置で衝止させることとしてもよい。
【００４１】
篩網１２の設置は篩網収納部２４の両側に設置された結合部４４，４４の溝４４１，４４１に縁１２１，１２１を挿入して行う。篩網１２の固定方法は特に限定されず、結合部４４を適宜の弾力性を有する材質で形成し或いは溝４４１の下面又は／及び上面に適宜の弾力性を有するシートを設置する等して溝４４１，４４１に縁１２１，１２１を嵌合させる等してもよいが、結合部４４，４４の夫々に上面から溝４４１に貫通する螺子孔４４２を穿孔し、把持部４５１を有する螺子４５を螺子孔４４２に螺入して縁１２１を溝４４１底面に押圧して篩網１２を固定することは推奨される。尚、把持部４５１には棒状取手４５２を水平方向に設置することとしてもよい。
【００４２】
連結材５は振動体４，４を連結、固定する為のものであり、板状或いは棒状の硬性部材で形成し、篩装置１中部背面部の枠体２に包囲された中空部２７，２７と一体となる空間にて振動体４，４を連結している。連結材５と振動体４の結合はボルトとナットを使用するが、溶接等により結合することとしてもよい。
【００４３】
載置台８は振動発生装置３を載置すると共に支持体４７，４７を設置する為の台である。振動発生装置３及び支持体４７，４７は該載置台８に固定されている。
【００４４】
振動吸収体１０は枠体２の中空部２７の底面２７１に適宜数設置し、載置台８を支持すると共に、振動発生装置３の振動による載置台８の振動を吸収し篩装置１の振動を防止するためのものである。振動吸収体１０はスプリング、弾力性を有する合成樹脂、スプリングを弾力性を有する合成樹脂にて被覆したもの等が使用される。
【００４５】
尚、振動吸収体１０と枠体２の中空部２７の底面２７１の間に更に載置台９及び振動吸収体１１，１１…を設置し、振動吸収体１０，１１と載置台８，９を二段重ねにして振動発生装置３の振動をより吸収して篩装置１自体の振動を防止することは推奨される。
【００４６】
篩網１２はふるいにかける粉粒体等に応じた適宜の形状の網目を有する上部外周が略正方形の方体状の籠状に形成すると共に、上部外周に渡って略正方形状に縁１２１を外方に張設する。縁１２１先端から他端の縁１２１先端の長さは結合部４４，４４の溝４４１，４４１の最深部間の長さと略同等に形成し、厚さは溝４４１の厚さと同等以下に形成する。この他に篩網１２の形状を半円籠状、上部外周が略長方形の方体状の籠状等に形成してもよい。この場合であっても上部外周に上述と同様の先端間の長さ及び厚さを有する縁１２１を外方に張設する。
【００４７】
容器１３は篩にかける粉粒体等を収納すると共に篩網１２に粉粒体等を供給する供給器たる容器であり、容器１４は篩にかけられた粉粒体等を受け収納する為の受給器たる容器である。容器１３と容器１４は同一形状に形成し、供給器としても受給器としても使用可能とすることは便である。容器１３及び容器１４は夫々底部に孔１３１，１４１を形成すると共に、上部外周に渡って供給器として使用する場合に容器１３を枠体２の載置部２８１に載置する為の側縁１３４、１４４を外方に張設する。容器１３，１４に粉粒体等を収納して運搬する場合には孔１３１，１４１にゴム、合成樹脂等により形成した孔蓋１３２，１４２にて孔１３１，１３２を被覆する。供給器として篩網１２に粉粒体等を供給する為に使用する場合には、枠体２の上面に形成した載置部２８１，２８１に側縁１３４，１３４を載置し、受給器として篩にかけられた粉粒体等を受け収納する為に使用する場合には、容器収納部２３に孔蓋１４２にて孔１４１を被覆した状態で設置する。尚、容器１３，１４は載置部２８１，２８１に載置される対向する上端部にのみ側縁１３４，１３４、１４４，１４４を形成することとしてもよく、更に容器１３，１４の運搬時に把持する棒状或いは取手状の把持部材１３５，１３５、１４５，１４５を適宜の対象位置に設けることは推奨される。
【００４８】
尚、粉粒体等を篩網１２に供給する供給器或いは篩網１２にて篩われた粉粒体等を収納する受給器としては上述のような容器１３，１４に限定されることなく、供給器としては他にベルトコンベアやホッパ等を用い、受給器としては他にベルトコンベアや袋等が使用可能である。
【００４９】
又、篩装置１には受給器の昇降手段を設けることは推奨される。昇降手段は、容器収納部２３の高さを容器１４の高さ以上に余裕を持って形成し、即ち、容器１４上端部と篩１２下端部に一定の距離生じさせて受給器たる容器１４の容器収納部２３への設置を容易としつつも、収納後に受給器たる容器１４を篩１２に近づけることにより、篩われた粉粒体の飛散を防止すると共に、篩われた粉粒体の凝集、団塊状化を防止し、容器１４に確実に粉粒体を収納するために有効な手段である。昇降手段は可動体１５，１５、押板１６、ロック機構１７から構成されている。
【００５０】
可動体１５は受給器たる容器１４を載置する支持台１５２と支持棒１５１から構成されている。支持棒１５１は縦断面が半円形に湾曲した部分と直線状の部分を有する棒状体或いは板状体等に形成し、枠体２の底面２３１に支持棒１５１，１５１が夫々挿通可能に形成した二本の長孔２３２，２３２に挿通して支持棒１５１の湾曲部分の一端を長孔２３２線上の枠体２の底面２３１に蝶番１５９等にて上下方向に回動自在に枢着する。支持台１５２は支持棒１５１を上面及び側面から被覆する長方形の箱状体に形成し、支持棒１５１湾曲部分の頂点に溶接等にて固定する。支持台１５２と支持棒１５１の強固な固定を得るために支持棒１５１湾曲部分の頂点に支持棒１５１に直交する棒状の補助材１５５を溶接等により固着し、補助材１５５を支持台１５２の側面に接触或いは貫通させて溶接等により固定することは推奨される。
【００５１】
支持台１５２の形状は長方形の箱状に限られることはなく、平板状、縦断面が半円形、三角錐等の形状としてもよいことは勿論である。更に、二本の支持棒１５１，１５１を被覆可能な方形の箱状体或いは平板形状の一体の支持台１５２を使用することとしてもよい。尚、支持台１５２は長孔２３２を覆う形状及び大きさに形成することは推奨される。又、受給器たる容器１４の着脱を容易とするために、支持台１５２の支持棒１５１への固定は可動体１５が最高位に位置する際に支持台１５２上面が水平になり、可動体１５が最低位に位置する際に支持台１５２上面が篩装置１の背面に向かって上昇した傾斜をなすように固定することは推奨される。
【００５２】
押板１６は可動体１５を上昇させるためのものである。押板１６は夫々板状体或いは棒状体にて側辺１６１，１６１と前辺１６２、後辺１６３を有する略方形に形成する。側辺１６１，１６１と前辺１６２を板状体にてコの字型に形成し、側辺１６１，１６１の先端部に孔を形成し、該孔に棒状体にて形成した後辺１６３を挿設することとしてもよい。前辺１６２の上面部は適宜幅、好ましくは５ｃｍ乃至１０ｃｍ程度に形成することは推奨される。押板１６は側辺１６１，１６１を枠体２の側面に平行に、前辺１６２、後辺１６３を枠体２の正面及び背面に平行に枠体２の底面２３１下面部に前辺１６２を枠体２の前面に張出して設置する。前辺１６２の枠体２の前面への張出のために枠体２の前面下部には側辺１６１，１６１の挿入のための切欠部２０１，２０１を形成する。押板１６の設置は、側辺１６１，１６１の中間部適宜位置に孔を形成すると共に、孔を有する枢支片１６９を枠体２の底面２３１下面部にボルト或いは溶接等により固着して、枢止片１６９の孔と側辺１６１の孔に枢止棒１６８を挿入して枠体２に押板１６を枢支する。後辺１６３上には支持棒１５１の枠体２に枢着されていない一端の直線状部分を載置する。
【００５３】
ロック機構１７はロック部材１７１、開放ペダル１７２から構成した押板１６を所望位置にて固定するための機構であり、ロック部材１７１はスナッチロック等を使用して押板１６から突設した把持棒１６６を把持固定させて押板１６を固定する。ロック部材１７１はロック部材１７１に形成された凹部に把持棒１６６が挿入された際にロックが掛かり、解放レバーの押圧操作によりロックが解放される構成にする等特に限定されるものではない。ロック部材１７１は枠体２の底面２３１下面部の押板１６の外側の側辺１６１近傍に一個を固定設置すればよいが、押板１６の外側の側辺１６１，１６１夫々の近傍に一個ずつを固定設置してもよい。押板１６の均一な位置固定のために把持棒１６６は一辺の側辺１６１にのみ固着させるのではなく、側辺１６１，１６１の両辺を貫通させて形成設置することは推奨される。開放ペダル１７２はバー１７３の先端にペダル１７４を固定して構成され、ロック部材１７のロック解放レバーにバー１７３を結合させ、ペダル１７４を枠体２の前面に張出して設置する。又、開放ペダル１７２の支持の為にバー１７３の挿通孔を有する支持片１７６を枠体２に固定設置する。
【００５４】

BACKGROUND OF THE INVENTION
The present invention relates to a sieving device, and more particularly, to a sieving device that can transmit vibrations generated by a vibration generator directly to a sieving mesh and that can realize an efficient sieving and can be easily attached and detached.
[0002]
[Prior art]
As a conventional sieve device, that is, a sieve device that vibrates the piston with an electromagnet, air or the like, or vibrates the sieve with a motor, an ultrasonic oscillator or the like, and sifts the powdery material such as wheat flour or granular material, etc. There are sieve devices disclosed in Japanese Patent Application Laid-Open No. 2001-129383, Japanese Patent Application Laid-Open No. 2000-135474, Japanese Patent Application Laid-Open No. 11-31860, Japanese Patent Application Laid-Open No. 11-128842, Japanese Patent Application Laid-Open No. 10-762229, and Japanese Patent Application Laid-Open No. 9-141205.
[0003]
These sieve devices are equipped with a vibration generator that generates vibrations at the bottom of the device, and a mechanism for discharging the sieved powder particles to the outside by installing a bottomed body with a sieve mesh at the top. There is something. In such a sieving apparatus, the granular material or the like hung on the sieve once falls to the first accumulating part, that is, the bottom of the bottomed body, slides on the first accumulating part, and the second accumulating part such as a collection container In this case, the granular material sieved in the meantime was aggregated and formed into a nodule, and the meaning applied to the sieve had been diminished.
[0004]
In addition, since the powder particles are discharged to the outside of the device, even if the device itself is downsized, it requires a place for placing a container or the like for receiving the powder particles discharged beside the device. Needed a large installation area. Furthermore, leakage from a container such as a granular material or powdered smoke is inevitable. Therefore, it is not suitable for use in a kitchen or the like where a limited area and a clean environment are required.
[0005]
In addition, there is a mechanism and device that removes powder particles remaining on the sieve mesh, but it is inevitable that the entire device will become large due to the installation of the mechanism and device, and a large installation place is required. And is not suitable for use in a limited narrow space.
[0006]
In addition, these sieve devices transmit the vibration generated by the vibration generator at the bottom of the device to the sieve mesh supported by a plurality of springs. It was not transmitted well, and the vibration was absorbed by the spring, and the speed of sieving was slow and the efficiency was not good. Further, when the efficiency of the sieve is obtained with such a configuration, the vibration generator as a power source has been enlarged.
[0007]
In addition, some vibration generators are installed on the side of the sieve mesh to directly apply vibration to the mechanism having the sieve mesh, but the mechanism having the sieve mesh is applied only to vibration from one end of the mechanism having the sieve mesh. Since it was hung on the connecting material, vibration was suppressed by the connecting material, and similarly, the vibration was not efficiently transmitted to the entire sieve screen, and the speed of sieving was slow, so that the efficiency was not good.
[0008]
Further, the above-mentioned apparatus having a sieve mesh or a mechanism having a sieve mesh is fixed to the apparatus, or is not easily removable. It was not easy to remove the powder particles remaining on the top, to wash and install the sieve mesh. In addition, in a device equipped with a mechanism or device for removing powder particles remaining on the sieve mesh, the mechanism needs to be attached and detached for cleaning and installation of the sieve mesh. Even if it becomes easy to remove the remaining powder and the like, it has become more difficult to clean and install the sieve screen.
[0009]
In addition, a vibration generator is installed on the side of the sieve mesh to directly apply vibrations to the mechanism having the sieve mesh, and the sieve mesh is used to remove powder particles remaining on the sieve mesh, to clean and install the sieve mesh. In addition, it is necessary to disassemble and attach / detach the mechanism having the dispersing blades and the connecting member that supports the mechanism, and it is complicated to remove the granular material remaining on the sieve screen, and to clean and install the sieve mesh.
[0010]
Further, when a motor or a piston is used, considerable noise is generated, and furthermore, since these vibration generators are directly installed on the sieve device, the vibration of the sieve device itself cannot be sufficiently suppressed. Further, these vibration generators are liable to break down due to vibration, powder particles, etc., and maintenance is not easy.
[0011]
[Problems to be solved by the invention]
