Description

【０００１】
【発明の属する技術分野】
この発明は飲料注出装置の注出機構に関し、更に詳細には、冷酒等の飲料充填容器に接続する注出チューブを押圧することで、該飲料充填容器に貯溜されている飲料の注出を規制すると共に、該チューブに対する押圧力を解除することで飲料の注出を許容する飲料注出装置の注出機構に関するものである。
【０００２】
【従来の技術】
飲料供給源と、この飲料供給源からの飲料の注出を制御する注出機構とから主に構成された飲料供給装置が広く使用されている。図１０に示すように、飲料供給装置１１は、適宜の加熱あるいは冷却機構(図示せず)を収納したキャビネット６８の上部に収納部７０を載置して構成されており、この収納部７０の内部に飲料充填容器７２を収納する収納室が画成されるようになっている。そして、加熱あるいは冷却機構により収納室を所定温度に保持することで、飲料充填容器７２内の飲料を適宜温度に保つよう構成される。また収納部７０におけるキャビネット６８の前面から突出する下部には、飲料充填容器７２に一端部が接続する注出チューブ２０が所定長さで垂下している。
【０００３】
前記飲料充填容器７２から導出する前記注出チューブ２０は、例えばゴム等の弾性変形可能な材質で成形されたものであって、図１１に示す如く、収納部下面に配設された注出機構７４によって開閉制御されるようになっている。この注出機構７４は、収納部下面に回動可能に軸支された注出レバー３２と、該レバー３２に配設されて前記注出チューブ２０の後側に臨む作動部材７８と、注出チューブ２０を挟んで作動部材７８と対向する前側に配設された押え部材８０と、前記注出レバー３２とキャビネット６８との間に弾力的に配設され、常には作動部材７８が押え部材８０に近接する方向に注出レバー３２を回動付勢するスプリング７６とから構成される。そして、前記スプリング７６の付勢力によって押え部材８０に近接する作動部材７８により注出チューブ２０が押潰されることで、前記飲料充填容器７２からの飲料の供給が規制されるようになっている。また飲料を受容器８１に注出するに際しては、該受容器８１を注出レバー３２に前側から押し付けてスプリング７６の付勢力に抗して回動させて、前記作動部材７８を押え部材８０から離間することで、該注出チューブ２０に対する押圧力が解除されて押潰された状態から元の連通状態に弾性復帰して開状態となって飲料が注出される。
【０００４】
【発明が解決しようとする課題】
前述した注出機構７４では、前記注出レバー３２にスプリング７６が直接接続されている。このため、飲料を注出するに際して注出レバー３２を押して回動するときには、前記スプリング７６の反発力が大きく増大するので、前記注出レバー３２に対する押圧力を高める必要がある。そしてこの押圧力を高めた状態を、前記受容器８１に飲料が充填されるまで保持しなければならないため、飲料の注出作業が煩わしくなる難点が指摘される。また、前記収納部７０から垂下する前記注出チューブ２０は何等支持されていないから、該チューブ２０が飲料の注出中に位置ズレした場合は、前記押え部材８０と作動部材７８とでの確実な押圧ができず、飲料が漏れる懸念がある。
【０００５】
【発明の目的】
本発明は、前述した従来の技術に内在している前記課題に鑑み、これを好適に解決するべく提案されたものであって、小さな押圧力で注出レバーを回動し得ると共に、注出チューブを確実に押圧して飲料の漏れを防止し得る飲料注出装置の注出機構を提供することを目的とする。
【０００６】
【課題を解決するための手段】
前記課題を解決し、所期の目的を達成するため、本発明に係る飲料注出装置の注出機構は、
注出レバーを飲料注出方向に回動することで、飲料充填容器に接続された注出チューブの押圧状態を解除し、該飲料充填容器に貯溜されている飲料を注出チューブを介して注出するよう構成した飲料注出装置において、
前記注出レバーの一端部が支持軸に回動可能に軸支された支持基台と、
前記注出チューブを挟んで押え部と対向するよう前記支持基台に摺動可能に配設され、常には付勢手段により押え部に近接するよう付勢されて、該押え部との間で注出チューブを押圧して飲料の注出を規制する押圧体と、
前記注出レバーの回動軌跡における飲料注出方向側に位置し、前記押圧体に回動可能に軸支された回動部材とからなり、
前記支持軸の軸心から回動部材と注出レバーとの当接位置までの離間距離に対し、注出レバーの他端部に形成した当接部から回動部材と注出レバーとの当接位置までの離間距離を長く設定し、
前記注出レバーを飲料注出方向に回動した際に、該レバーに当接した状態で前記回動部材が、注出レバーに沿って前記当接部から回動部材と注出レバーとの当接位置までの離間距離が長くなる方向へ移動することにより前記押圧体が押え部から離間移動されることで、前記注出チューブの押圧力を解除して飲料を注出するよう構成したことを特徴とする。
【０００７】
【発明の実施の形態】
次に、本発明に係る飲料注出装置の注出機構につき、好適な実施例を挙げて、添付図面を参照しながら以下説明する。なお、飲料注出装置の基本構成は、図１０,図１１を参照して説明した従来の技術と略同一であるので、既出の同一部材については、同じ符号を付して示し、その詳細説明は省略する。
【０００８】
図１は、実施例に係る注出機構を示す正面図であり、図２は、実施例に係る注出機構を一部破断した側面図である。該注出機構１０は、前記飲料供給装置１１の収納部７０下面に、幅方向に離間する一対の側板１３ａ,１３ｂを下面前部において接続片４６で連結したフレーム１３が支持固定され、該フレーム１３の内部に、支持基台１２が固定的に設置されている。この支持基台１２は、合成樹脂を材料として断面略矩形状に成形されたブロック体であって、その後端近傍には、上側に第１貫通孔１２ａが幅方向に沿って形成されると共に、下側に第２貫通孔１２ｂが幅方向に沿って形成されている。また前端上部には、支持基台１２の高さ寸法の約１／４の部分が、支持基台１２の前方に向けて所定長さで突出成形されており、この突出部１２ｄに、支持基台１２の幅方向に沿って第３貫通孔１２ｃが形成してある。そして第１貫通孔１２ａに第１支持軸１４が挿通配置されると共に、第２および第３貫通孔１２ｂ,１２ｃに第２支持軸１６が夫々挿通配置されており、各第２支持軸１６は、その両軸端部が前記フレーム１３の両側板１３ａ,１３ｂに支持されている。
【０００９】
前記各第２支持軸１６は、図４に示すように、支持基台１２の幅方向一方に延出する部分が、第２貫通孔１２ｂまたは第３貫通孔１２ｃに挿通される小径部１６ｂよりも若干大径に設定されている。そして、各第２支持軸１６の小径部１６ｂを前記フレーム１３の一方の側板１３ａ側から第２貫通孔１２ｂまたは第３貫通孔１２ｃに挿通した状態で、該フレーム１３の他方の側板１３ｂ側から挿通されるスリーブ１６ｃに該小径部１６ｂの開放端部を嵌挿することで、支持基台１２がフレーム１３に位置決め支持される。なお、各第２支持軸１６の大径部１６ａの開放端に形成されたフランジ１６ｄをフレーム１３の一方の側板１３ａの外側面に当接すると共に、フレーム１３の他方の側板１３ｂから外方に突出する小径部１６ｂの開放端部側にＥリング１９を係合することで、該第２支持軸１６の抜け止めがなされている。また第２支持軸１６の大径部１６ａとスリーブ１６ｃとの間で位置決めされる支持基台１２は、フレーム１３の略中央に整列するよう構成される。
【００１０】
前記支持基台１２の第１貫通孔１２ａに挿通配置された第１支持軸１４には、図１および図３に示す如く、注出レバー３２の一端部が回動可能に軸支されている。この注出レバー３２は、幅方向に離間する一対のアーム１８,１８の下端を接続板３４で連結したアーム部２１と、接続板３４に連結されて所要傾斜角度で前方に向けて垂下するレバー部２３とから構成され、両アーム１８,１８の上端部が、支持基台１２の幅方向両側から延出している第１支持軸１４に軸支されている。各アーム１８は、第１支持軸１４に軸支された部分から支持基台１２の前面側に向けて所定長さ延在する水平部１８ａの前端に、後方に開放するＶ字状の係合部１８ｂが一体に成形されたものであって、該係合部１８ｂの下端が前記接続板３４に連結されている。そして、各アーム１８における係合部１８ｂの谷側(後側)が、後述するローラ２４に当接するようになっている。
【００１１】
なお、前記第１支持軸１４に対して一方(図１の右側)のアーム１８は、第１支持軸１４の一方の軸端に形成したフランジ１４ａと該支持軸１４に外嵌したカラー１７との間に位置決めされ、また他方(図１の左側)のアーム１８は、第１支持軸１４の他方の軸端に係合したＥリング１５と該支持軸１４に外嵌したカラー１７との間に位置決めされている。また前記レバー部２３は、前記フレーム１３の接続片４６より後方において、両側板１３ａ,１３ｂの間から垂下し、該レバー部２３の後方(飲料注出方向)への回動に際してフレーム１３と干渉しないようになっている。
【００１２】
前記支持基台１２における突出部１２ｄの下方位置には、図２に示すように、前面中央を中心として前方に開放する円形の凹部１２ｆが、該基台１２の前後方向に沿って略中央部まで凹設されると共に、該凹部１２ｆよりも小径に設定された通孔１２ｇが、凹部１２ｆと軸心を整列した状態で前後に貫通するよう形成されている。そして、この凹部１２ｆおよび通孔１２ｇに、押圧体２２が摺動可能に配設される。この押圧体２２は、図２に示すように、凹部１２ｆ内を摺動する大径部２２ａと、該大径部２２ａの後端に軸心を整列して後方に所定長さで延出するよう一体形成されたシャフト２２ｂおよび大径部２２ａの前端に配設される押圧板部２２ｃとから構成される。前記大径部２２ａは、凹部１２ｆの延在長さよりも若干短い寸法で成形された円柱状部材であって、該大径部２２ａの後端と凹部１２ｆの対向する内底面との間に付勢手段としてのスプリング２６が弾力的に介挿され、当該押圧体２２は、常には支持基台１２の前面側に向けて付勢されている。また前記シャフト２２ｂは、支持基台１２の後面側から突出する延在部分に、Ｅリング等の止着部材２８が係合されている。この止着部材２８は、大径部２２ａが凹部１２ｆから完全に離脱するのを防止する位置に係合配置される。前記押圧板部２２ｃは、大径部２２ａの前面部をカバーし得る高さ幅で延在する板部材であって、図１に示す如く、該大径部２２ａの横幅よりも若干幅広に設定されて、注出チューブ２０の後側に臨んでいる。
【００１３】
なお、前記支持基台１２における凹部１２ｆと対応する下部に、凹部１２ｆと外部とを連通する抜け孔１２ｈが穿設されており、該抜け孔１２ｈは、凹部１２ｆ内の空気抜きを行なって押圧体２２の良好な動きを行なわせると共に、水抜きも兼ねている。
【００１４】
前記押圧体２２には、大径部２２ａと押圧板部２２ｃとの間に、平面において後方に開放するコ字状に形成された保持部材２９が配設され、該保持部材２９の幅方向に離間する一対の保持部２９ａ,２９ａは、前記支持基台１２を幅方向両側から挟む状態で臨んでいる。各保持部２９ａの後端部近傍には、回動部材としてのローラ２４が回動可能に軸支されており、該ローラ２４が対応する前記アーム１８における係合部１８ｂの後側に当接可能に構成される。そして、前記注出レバー３２を、レバー部２３に形成した当接部２３ａに前記受容器８１を当接して後方に向けて押すことで、第１支持軸１４を支点に注出レバー３２が回動する。そして、アーム１８,１８の係合部１８ｂ,１８ｂがローラ２４,２４に当接して押圧することによって、前記押圧体２２がスプリング２６の弾力(付勢力)に抗しつつ支持基台１２の後側に向けて移動するよう構成される。すなわち、ローラ２４と係合部１８ｂとの当接位置が、注出レバー３２を回動する際の作用点となる。なお、各ローラ２４の支持基台１２から離間する軸端部に、該ローラ２４よりも大径のワッシャ３６が配設され、前記注出レバー３２を回動して押圧体２２を移動させる際に、各アーム１８がローラ２４から離脱しないよう構成されている。
【００１５】
前記保持部材２９の大径部２２ａが配設される取付部２９ｂは、前記押圧体２２がスプリング２６により付勢されて前方に移動し、後述する押え部４２と押圧板部２２ｃとの間で前記注出チューブ２０を押潰して飲料の注出を規制している状態では、前記支持基台１２の前面から所定長さだけ前方に離間している。そして、前記注出レバー３２の回動に伴って押圧体２２の押圧板部２２ｃが、注出チューブ２０から離間して押圧力を解除して飲料の注出が可能となる位置まで押圧体２２が移動したときに、前記取付部２９ｂが支持基台１２の前面に当接して、注出レバー３２の回動を規制するよう構成される(図５参照)。なお、保持部材２９により注出レバー３２の回動が規制される位置は、該レバー３２が前記キャビネット６８等に当接しない位置に設定されており、キャビネット６８や注出レバー３２自体が傷付くのを防止するようになっている。
【００１６】
ここで、前記第１支持軸１４の軸心から前記作用点(ローラ２４と係合部１８ｂとの当接位置)までの離間距離Ａに対し、前記レバー部２３の当接部２３ａから作用点までの離間距離Ｂは充分に長く設定されており、てこの原理により前記スプリング２６の弾力に抗して注出レバー３２を回動するのに要する押圧力を小さくし得るよう構成される。また、前記注出レバー３２を、第１支持軸１４を支点として後方(飲料注出方向)に回動する際には、前記作用点が係合部１８ｂの傾斜に沿って移動する。すなわち、第１支持軸１４の軸心から作用点までの離間距離Ａに対し、前記レバー部２３の当接部２３ａから作用点までの離間距離Ｂは、注出レバー３２を飲料注出方向に回動するにつれて長くなる。これによって、前記スプリング２６の弾力に抗して注出レバー３２を回動するのに要する押圧力が、その回動に伴って大きくなるのを抑制している。
【００１７】
前記フレーム１３における一方の側板１３ａの前端に、大型のヒンジ３８を介して蓋部４０が回動可能に軸支されており、該蓋部４０の後面側に、断面半円状に成形されて幅方向に所定長さ寸法を有する押え部４２が配設される。そしてこの押え部４２は、蓋部４０によりフレーム１３の前側開口部(両側板間)を閉成した際に、前記押圧体２２の押圧板部２２ｃと注出チューブ２０を挟んで対向し、両部材２２ｃ,４２により該チューブ２０を押潰して飲料の注出を規制し得るよう構成される。なお、蓋部４０の軸支部とは反対の端部にラッチ４４が配設されており、該蓋部４０を回動してラッチ４４をフレーム１３における他方の側板１３ｂの対応位置に形成された切欠１３ｃに係合することにより、蓋部４０がフレーム１３に位置決め保持されるようになっている。
【００１８】
前記支持基台１２における突出部１２ｄの前端面に、前記飲料充填容器７２に接続した注出チューブ２０を支持するための係合部１２ｅが形成されている。この係合部１２ｅは、注出チューブ２０の直径よりも若干大径の円弧状に凹設されており、該係合部１２ｅに挿通された注出チューブ２０は、前記押圧板部２２ｃと押え部４２との間に正確に臨むよう構成される。また、前記フレーム１３における接続片４６の前端部に、前記係合部１２ｅと上下に整列する係合部４６ａが形成されている。この係合部４６ａは、前記係合部１２ｅと同様の円弧状に形成されており、該係合部４６ａに注出チューブ２０を挿通支持することで、該チューブ２０は、押圧板部２２ｃと押え部４２とで押圧される位置の上下で支持されるようになっている。なお、図１において符号７０ａは、前記収納部７０に形成された案内溝であって、前記飲料充填容器７２から導出する注出チューブ２０は、該案内溝７０ａに案内支持された後に、前記係合部１２ｅに導びかれるよう構成してある。
【００１９】
【実施例の作用】
次に、前述した実施例に係る飲料注出装置の注出機構の作用につき説明する。前記蓋部４０を閉位置に保持した状態では、前記飲料充填容器７２から導出して上下の係合部１２ｅ,４６ａに挿通支持されている注出チューブ２０は、前記押え部４２に対してスプリング２６により弾力付勢されている押圧体２２の押圧板部２２ｃにより押潰されて、飲料の注出が規制されている(図３参照)。前記受容器８１に飲料を注出するに際し、該受容器８１で前記注出レバー３２のレバー部２３における当接部２３ａを後方に押すと、該注出レバー３２が前記第１支持軸１４を支点として回動する。このとき、注出レバー３２における各アーム１８の係合部１８ｂが、前記押圧体２２に回動可能に軸支された対応のローラ２４に当接し、該ローラ２４が回動しつつ押圧体２２が前記スプリング２６の弾力に抗して押え部４２から離間移動されることで、前記注出チューブ２０に対する押圧力が解除され、該チューブ２０から飲料が受容器８１に注出される(図５参照)。
【００２０】
前述した注出レバー３２の回動に際し、前記スプリング２６が圧縮されることで、その弾力が徐々に大きくなる。この場合において、前記第１支持軸１４の軸心から前記作用点までの離間距離Ａに対し、前記レバー部２３の当接部２３ａから作用点までの離間距離Ｂは充分に長く設定されているから、てこの原理によりスプリング２６の弾力に抗して注出レバー３２を回動するのに要する押圧力は小さくて足りる。しかも、実施例の注出機構１０では、注出レバー３２の回動に際し、前記アーム１８の係合部１８ｂとローラ２４との当接位置、すなわち注出レバー３２の作用点は、前記第１支持軸１４の軸心から作用点までの離間距離Ａに対し、前記レバー部２３の当接部２３ａから作用点までの離間距離Ｂが徐々に長くなるよう変化する。これにより、前記スプリング２６の弾力が徐々に大きくなっても、注出レバー３２を回動するのに要する押圧力は小さな一定の力で足り、注出作業を楽に行ない得る。
【００２１】
なお、前記押圧体２２の保持部材２９が支持基台１２に当接することで注出レバー３２の回動が規制されるので、該レバー３２が必要以上に回動されることで、前記キャビネット６８や注出レバー３２自体が傷付くのは防止される。また前記支持基台１２に設けた抜け孔１２ｈにより、前記押圧体２２の円滑な移動が達成される。
【００２２】
前記受容器８１への飲料の注出が終了した後は、該受容器８１を注出レバー３２から離間させる。これにより、前記押圧体２２がスプリング２６の弾力によって支持基台１２の前方に押圧移動され、前記押え部４２と押圧板部２２ｃとで前記注出チューブ２０が押潰されて、飲料の注出が規制される。このとき注出チューブ２０は、前記支持基台１２の係合部１２ｅおよび接続片４６の係合部４６ａに支持されているから、押圧体２２が前方に移動する際に注出チューブ２０が左右にズレることなく、押え部４２との間で確実に押圧し得る。また、押圧体２２は支持基台１２に案内されて軸心がズレることなく直線的に移動するので、該押圧体２２の押圧板部２２ｃが注出チューブ２０に接触した際のズレも生じない。しかも、前記押圧板部２２ｃおよび押え部４２は、注出チューブ２０の直径に対して充分に長い幅寸法に設定されているから、仮に注出チューブ２０がズレていても、確実に押圧して押潰すことができ、飲料漏れを防止し得る。なお、押え部４２をフレーム１３に軸支するヒンジ３８を大型としてあるので、該押え部４２のガタは少なく、押え部４２のガタ付きにより注出チューブ２０の押圧が不十分となることはない。
【００２３】
前記押圧体２２がスプリング２６の弾力によって支持基台１２の前方に押圧される際には、該押圧体２２のローラ２４,２４を介して注出レバー３２が第１支持軸１４を支点として前方へ回動して元の位置に戻る。このとき、前述したてこの原理により、注出レバー３２に作用するスプリング２６の弾力は小さく、該注出レバー３２が勢いよく回動することを抑制して耐久性を向上し得る。
【００２４】
【変更例】
前述した実施例では、前記押圧板部２２ｃと押え部４２との押圧部位より上方の注出チューブ２０を、前記支持基台１２に設けた係合部１２ｅで支持するよう構成したが、例えば図６に示す固定部材４８を用いて注出チューブ２０の対応位部を支持するようにしてもよい。この固定部材４８は、板材を断面略コ字状に形成したものであって、垂直な基板部４８ｃの上端縁に折曲形成された上部短辺部４８ａには、前方に向けて平行に延在する２本の支持棒５０,５０が、注出チューブ２０の挿通を許容する離間幅で配設されている。そしてこの固定部材４８は、該支持棒５０,５０の先端部が前記フレーム１３の前端部に略整列する状態で前記支持基台１２の前面に配設される。また前記基板部４８ｃの中央には、前記押圧体２２の大径部２２ａが挿通可能な挿通孔４８ｂが穿設されており、該基板部４８ｃの前側に臨む押圧板部２２ｃで注出チューブ２０を押潰す際に、その直上方において該チューブ２０を一対の支持棒５０,５０で支持して位置ズレを防止し得るようになっている。
【００２５】
なお、前記固定部材４８は、前述した実施例に係る注出機構１０とは別構造の注出機構５２に配設して使用することもできる。この別の注出機構５２は、図７〜図９に示す如く、前記フレーム１３の内部に、ソレノイド等のアクチュエータ５６を備え、その前方に突出するプランジャ５４が、前記フレーム１３に配設した固定部材４８の挿通孔４８ｂを介して前方に延出している。前記プランジャ５４の先端部には、合成樹脂あるいは硬質ゴム等からなる押圧体５８が配設されると共に、該押圧体５８と固定部材４８の基板部４８ｃとの間にスプリング６０が弾力的に配設され、該押圧体５８は、常にはフレーム１３にヒンジ６４を介して配設した前述したと同一構成の蓋部６２の押え部６６に近接し、両者５８,６６で注出チューブ２０を押潰して飲料の注出を規制するよう構成される。
【００２６】
前述した状態で、前記アクチュエータ５６が付勢されると、スプリング６０の弾力に抗してプランジャ５４がアクチュエータ５６の本体側に後退する。これによって、前記注出チューブ２０に対する押圧力が解除され、該チューブ２０から飲料が注出される(図９参照)。そして、飲料の注出が終了するタイミングでアクチュエータ５６の付勢が解除されると、図９に示す如く、スプリング２６の弾力によって押圧体５８が押え部６６に向けて移動し、前記注出チューブ２０を押潰して飲料の注出を規制する。このとき注出チューブ２０は、押圧体５８と押え部６６とによる押圧部位の直上方において、前記支持棒５０,５０によって左右方向の移動が規制されているため、該注出チューブ２０を押圧体５８と押え部６６との間で確実に押圧し、飲料漏れを防止し得る。
【００２７】
【発明の効果】
以上説明した如く、本発明に係る飲料注出装置の注出機構では、押え部との間で注出チューブを押圧する押圧体を、注出レバーを用いたてこの原理により、付勢手段の付勢力に抗して移動させるよう構成したから、該レバーを回動するのに要する押圧力を小さくでき、注出作業を楽に行なうことができる。また、押圧体は支持基台に案内されて移動するので、該押圧体は安定して移動し得る。更に、押圧体の上方において注出チューブを支持する係合部を備えているから、該チューブの位置ズレを防止して押え部と押圧体とで注出チューブを確実に押圧して押潰すことができ、飲料漏れを防止し得る。更にまた注出機構では、注出レバーの回動に際し、注出レバーと回動部材との当接位置は、支持軸の軸心から作用点までの離間距離に対し、当接部から作用点までの離間距離が徐々に長くなるよう変化するから、付勢手段が圧縮されることで付勢手段の弾力が徐々に大きくなっても、注出レバーを回動するのに要する押圧力は小さな一定の力で足り、注出作業を楽に行ない得る。

The present invention relates to a dispensing mechanism of a beverage dispensing device that regulates and permits dispensing of a beverage by releasing a pressing force on the tube.
[0002]
[Prior art]
A beverage supply device mainly composed of a beverage supply source and a dispensing mechanism that controls the dispensing of beverage from the beverage supply source is widely used. As shown in FIG. 10, the beverage supply device 11 is configured by placing a storage unit 70 on an upper part of a cabinet 68 that stores an appropriate heating or cooling mechanism (not shown). A storage chamber for storing the beverage filling container 72 is defined therein. And it hold | maintains a storage chamber at predetermined temperature with a heating or cooling mechanism, and it is comprised so that the drink in the drink filling container 72 may be kept at temperature appropriately.

Open / close control is performed by 74. The pouring mechanism 74 includes a pouring lever 32 pivotally supported on the lower surface of the storage portion, an operating member 78 disposed on the lever 32 and facing the rear side of the pouring tube 20, and pouring The holding member 80 disposed on the front side facing the actuating member 78 across the tube 20 is elastically disposed between the extraction lever 32 and the cabinet 68, and the actuating member 78 is always held by the pressing member 80. And a spring 76 that urges the pouring lever 32 in a direction in the vicinity thereof. The supply of beverage from the beverage filling container 72 is restricted by the squeezing tube 20 being crushed by the actuating member 78 close to the presser member 80 by the urging force of the spring 76. When the beverage is poured into the receptacle 81, the receptacle 81 is pressed against the dispensing lever 32 from the front side and rotated against the urging force of the spring 76, so that the operating member 78 is moved from the pressing member 80. By separating, the pressing force on the dispensing tube 20 is released and the crushed state is elastically restored to the original communication state, and the beverage is poured out.
[0004]
[Problems to be solved by the invention]
In the dispensing mechanism 74 described above, a spring 76 is directly connected to the dispensing lever 32. For this reason, when the drink lever 32 is pushed and rotated, the repulsive force of the spring 76 is greatly increased, so that it is necessary to increase the pressing force on the dispense lever 32. And since the state which raised this pressing force must be hold | maintained until a drink is filled in the said receiver 81, the difficulty which becomes difficult to pour out a drink is pointed out. In addition, since the dispensing tube 20 that hangs down from the storage portion 70 is not supported at all, when the tube 20 is misaligned during the dispensing of the beverage, the pressing member 80 and the actuating member 78 can be reliably connected. There is a concern that the beverage cannot be pressed and the beverage leaks.

The E-ring 19 is engaged with the open end side of the small diameter portion 16b to prevent the second support shaft 16 from coming off. The support base 12 positioned between the large-diameter portion 16 a of the second support shaft 16 and the sleeve 16 c is configured to align with the approximate center of the frame 13.
[0010]
As shown in FIGS. 1 and 3, one end of the dispensing lever 32 is pivotally supported on the first support shaft 14 inserted and disposed in the first through hole 12 a of the support base 12. . The pouring lever 32 includes an arm portion 21 in which the lower ends of a pair of arms 18 and 18 that are separated in the width direction are coupled by a connection plate 34, and a lever that is coupled to the connection plate 34 and hangs forward at a required inclination angle. The upper ends of both arms 18 and 18 are pivotally supported by a first support shaft 14 extending from both sides of the support base 12 in the width direction. Each arm 18 has a V-shaped engagement that opens rearward at a front end of a horizontal portion 18a extending a predetermined length from a portion pivotally supported by the first support shaft 14 toward the front side of the support base 12. The portion 18b is integrally formed, and the lower end of the engaging portion 18b is coupled to the connection plate 34. And the trough side (rear side) of the engaging part 18b in each arm 18 comes into contact with a roller 24 described later.
[0011]
Note that one arm 18 (on the right side in FIG. 1) with respect to the first support shaft 14 includes a flange 14 a formed at one shaft end of the first support shaft 14 and a collar 17 externally fitted to the support shaft 14. The other arm 18 (left side in FIG. 1) is positioned between the E-ring 15 engaged with the other shaft end of the first support shaft 14 and the collar 17 fitted on the support shaft 14. Is positioned. The lever portion 23 hangs down from between the side plates 13a and 13b behind the connection piece 46 of the frame 13, and interferes with the frame 13 when the lever portion 23 is rotated rearward (beverage dispensing direction). It is supposed not to.
[0012]
As shown in FIG. 2, a circular recess 12 f that opens forward from the center of the front surface is formed at a substantially central portion along the front-rear direction of the base 12 at a position below the protrusion 12 d of the support base 12. A through hole 12g having a diameter smaller than that of the recess 12f is formed so as to penetrate in the front-rear direction in a state where the recess 12f and the axis are aligned. The pressing body 22 is slidably disposed in the recess 12f and the through hole 12g. As shown in FIG. 2, the pressing body 22 has a large-diameter portion 22a that slides in the recess 12f, and an axial center aligned with the rear end of the large-diameter portion 22a and extends backward by a predetermined length. The shaft 22b and the pressing plate portion 22c disposed at the front end of the large diameter portion 22a are integrally formed. The large-diameter portion 22a is a columnar member formed with a dimension slightly shorter than the extending length of the recess 12f, and is attached between the rear end of the large-diameter portion 22a and the inner bottom surface facing the recess 12f. A spring 26 as a biasing means is elastically inserted, and the pressing body 22 is always biased toward the front surface side of the support base 12. Further, the shaft 22b is engaged with a fastening member 28 such as an E ring at an extending portion protruding from the rear surface side of the support base 12. The fastening member 28 is engaged and disposed at a position that prevents the large-diameter portion 22a from being completely detached from the recess 12f. The pressing plate portion 22c is a plate member extending at a height that can cover the front surface portion of the large-diameter portion 22a, and is set to be slightly wider than the lateral width of the large-diameter portion 22a as shown in FIG. Then, it faces the rear side of the dispensing tube 20.
[0013]
In the lower part of the support base 12 corresponding to the concave portion 12f, a through hole 12h that communicates the concave portion 12f with the outside is formed, and the through hole 12h vents the air inside the concave portion 12f to press the pressing body. 22 good movements, and also drains water.
[0014]
The pressing body 22 is provided with a holding member 29 formed in a U shape that opens rearward in a plane between the large-diameter portion 22 a and the pressing plate portion 22 c, and extends in the width direction of the holding member 29. A pair of spaced apart holding portions 29a, 29a face the support base 12 from both sides in the width direction. A roller 24 as a rotating member is pivotally supported in the vicinity of the rear end of each holding portion 29a, and the roller 24 contacts the rear side of the engaging portion 18b in the corresponding arm 18. Configured to be possible. Then, by pushing the receptacle 81 against the abutment portion 23a formed on the lever portion 23 and pushing the receptacle 81 backward, the dispensing lever 32 rotates around the first support shaft 14 as a fulcrum. Move. The engaging portions 18b and 18b of the arms 18 and 18 abut against and press the rollers 24 and 24 so that the pressing body 22 resists the elastic force (biasing force) of the spring 26 and the rear of the support base 12. Configured to move toward the side. That is, the contact position between the roller 24 and the engaging portion 18b becomes an action point when the extraction lever 32 is rotated. In addition, a washer 36 having a diameter larger than that of the roller 24 is disposed at the end of the shaft that is separated from the support base 12 of each roller 24, and when the pusher lever 32 is rotated to move the pressing body 22. In addition, each arm 18 is configured not to be detached from the roller 24.
[0015]
The attachment portion 29b in which the large-diameter portion 22a of the holding member 29 is disposed is moved forward by the pressing body 22 being urged by the spring 26, and between a pressing portion 42 and a pressing plate portion 22c described later. In a state where the dispensing tube 20 is crushed and the dispensing of the beverage is restricted, the dispensing tube 20 is spaced forward from the front surface of the support base 12 by a predetermined length. As the dispensing lever 32 rotates, the pressing plate 22c of the pressing body 22 moves away from the dispensing tube 20 to release the pressing force and to the position where the beverage can be dispensed. Is moved, the mounting portion 29b comes into contact with the front surface of the support base 12 to restrict the rotation of the dispensing lever 32 (see FIG. 5). The position at which the rotation of the dispensing lever 32 is restricted by the holding member 29 is set to a position where the lever 32 does not contact the cabinet 68 and the like, and the cabinet 68 and the dispensing lever 32 itself are damaged. It is designed to prevent this.
[0016]
Here, with respect to the separation distance A from the axial center of the first support shaft 14 to the action point (the contact position between the roller 24 and the engagement part 18b), the action point from the contact part 23a of the lever part 23. The separation distance B is set to be sufficiently long, and the pressing force required to rotate the dispensing lever 32 against the elasticity of the spring 26 can be reduced by the lever principle. Further, when the dispensing lever 32 is rotated rearward (beverage dispensing direction) with the first support shaft 14 as a fulcrum, the action point moves along the inclination of the engaging portion 18b. That is, with respect to the separation distance A from the axial center of the first support shaft 14 to the action point, the separation distance B from the contact part 23a of the lever part 23 to the action point causes the dispensing lever 32 to be in the beverage dispensing direction. It becomes longer as it turns. As a result, the pressing force required to rotate the extraction lever 32 against the elasticity of the spring 26 is suppressed from increasing with the rotation.
[0017]
A lid 40 is pivotally supported at the front end of one side plate 13a of the frame 13 via a large hinge 38, and is formed in a semicircular cross section on the rear surface side of the lid 40. A presser portion 42 having a predetermined length dimension is disposed in the width direction. Then, when the front side opening (between both side plates) of the frame 13 is closed by the lid portion 40, the pressing portion 42 is opposed to the pressing plate portion 22c of the pressing body 22 with the extraction tube 20 interposed therebetween. The tube 22 is crushed by the members 22c and 42 so that the dispensing of the beverage can be restricted. Note that a latch 44 is disposed at the end of the lid 40 opposite to the shaft support, and the latch 44 is formed at a position corresponding to the other side plate 13b of the frame 13 by rotating the lid 40. The lid portion 40 is positioned and held on the frame 13 by engaging with the notch 13c.
[0018]
An engaging portion 12e for supporting the dispensing tube 20 connected to the beverage filling container 72 is formed on the front end surface of the protruding portion 12d of the support base 12. The engaging portion 12e is recessed in an arc shape that is slightly larger in diameter than the diameter of the pouring tube 20, and the pouring tube 20 inserted through the engaging portion 12e is pressed against the pressing plate portion 22c. It is configured to face the part 42 accurately. In addition, an engaging portion 46a that is vertically aligned with the engaging portion 12e is formed at the front end portion of the connection piece 46 in the frame 13. The engaging portion 46a is formed in an arc shape similar to the engaging portion 12e. By inserting and supporting the extraction tube 20 through the engaging portion 46a, the tube 20 is connected to the pressing plate portion 22c. It is supported above and below the position pressed by the pressing portion 42. In FIG. 1, reference numeral 70a denotes a guide groove formed in the storage portion 70, and the dispensing tube 20 led out from the beverage filling container 72 is guided and supported by the guide groove 70a, and then the engagement groove 70a. It is configured to be guided to the joint portion 12e.
[0019]
[Effect of the embodiment]
Next, the operation of the dispensing mechanism of the beverage dispensing apparatus according to the above-described embodiment will be described. In a state where the lid portion 40 is held in the closed position, the dispensing tube 20 that is led out from the beverage filling container 72 and inserted and supported by the upper and lower engaging portions 12e, 46a is a spring against the presser portion 42. The beverage is crushed by the pressing plate portion 22c of the pressing body 22 that is elastically biased by 26, and the dispensing of the beverage is restricted (see FIG. 3). When the beverage is dispensed into the receptacle 81, when the receptacle 81 pushes the contact portion 23 a of the lever portion 23 of the dispensing lever 32 backward, the dispensing lever 32 pushes the first support shaft 14. It rotates as a fulcrum. At this time, the engaging portion 18b of each arm 18 in the dispensing lever 32 comes into contact with a corresponding roller 24 pivotally supported by the pressing body 22, and the pressing body 22 rotates while the roller 24 rotates. Is moved away from the presser portion 42 against the elasticity of the spring 26, the pressing force on the dispensing tube 20 is released, and the beverage is poured from the tube 20 to the receiver 81 (see FIG. 5). ).
[0020]
When the dispensing lever 32 is rotated, the spring 26 is compressed, so that its elasticity gradually increases. In this case, the separation distance B from the contact portion 23a of the lever portion 23 to the action point is set sufficiently longer than the separation distance A from the axis of the first support shaft 14 to the action point. Therefore, the pressing force required to rotate the pouring lever 32 against the elasticity of the spring 26 by the lever principle is small. Moreover, in the dispensing mechanism 10 of the embodiment, when the dispensing lever 32 is rotated, the contact position between the engaging portion 18b of the arm 18 and the roller 24, that is, the operating point of the dispensing lever 32 is the first point. The separation distance B from the contact portion 23a of the lever portion 23 to the action point changes gradually with respect to the separation distance A from the axis of the support shaft 14 to the action point. As a result, even if the elasticity of the spring 26 gradually increases, the pressing force required to rotate the dispensing lever 32 is sufficient with a small constant force, and the dispensing operation can be performed easily.
[0021]
Since the holding member 29 of the pressing body 22 abuts on the support base 12, the rotation of the dispensing lever 32 is restricted. Therefore, when the lever 32 is rotated more than necessary, the cabinet 68. In addition, the dispensing lever 32 itself is prevented from being damaged. In addition, smooth movement of the pressing body 22 is achieved by the through holes 12 h provided in the support base 12.
[0022]
After the beverage has been dispensed into the receptacle 81, the receptacle 81 is separated from the dispensing lever 32. As a result, the pressing body 22 is pressed and moved forward of the support base 12 by the elasticity of the spring 26, and the discharging tube 20 is crushed by the pressing portion 42 and the pressing plate portion 22c, thereby discharging the beverage. Is regulated. At this time, since the extraction tube 20 is supported by the engagement portion 12e of the support base 12 and the engagement portion 46a of the connection piece 46, the extraction tube 20 is moved to the left and right when the pressing body 22 moves forward. It is possible to reliably press between the presser part 42 without shifting. Further, since the pressing body 22 is guided by the support base 12 and moves linearly without shifting its axis, there is no deviation when the pressing plate portion 22c of the pressing body 22 contacts the dispensing tube 20. . Moreover, since the pressing plate portion 22c and the holding portion 42 are set to have a sufficiently long width with respect to the diameter of the extraction tube 20, even if the extraction tube 20 is misaligned, it is surely pressed. It can be crushed and beverage leakage can be prevented. In addition, since the hinge 38 that pivotally supports the presser portion 42 on the frame 13 is made large, the play of the presser portion 42 is small, and the pressing of the discharge tube 20 is not insufficient due to the play of the presser portion 42. .
[0023]
When the pressing body 22 is pressed forward of the support base 12 by the elasticity of the spring 26, the dispensing lever 32 moves forward with the first support shaft 14 as a fulcrum through the rollers 24, 24 of the pressing body 22. To return to the original position. At this time, due to the principle of the lever described above, the elasticity of the spring 26 acting on the dispensing lever 32 is small, and the durability can be improved by suppressing the dispensing lever 32 from rotating vigorously.
[0024]
[Example of change]
In the embodiment described above, the extraction tube 20 above the pressing portion of the pressing plate portion 22c and the pressing portion 42 is supported by the engaging portion 12e provided on the support base 12. The corresponding position portion of the extraction tube 20 may be supported using the fixing member 48 shown in FIG. The fixing member 48 is formed by forming a plate material with a substantially U-shaped cross section. The fixing member 48 extends in parallel toward the front on an upper short side portion 48a bent at the upper edge of the vertical substrate portion 48c. The two existing support rods 50 and 50 are disposed with a separation width that allows insertion of the extraction tube 20. The fixing member 48 is disposed on the front surface of the support base 12 in such a state that the front ends of the support rods 50 and 50 are substantially aligned with the front end of the frame 13. An insertion hole 48b through which the large-diameter portion 22a of the pressing body 22 can be inserted is formed in the center of the substrate portion 48c, and the extraction tube 20 is formed by the pressing plate portion 22c facing the front side of the substrate portion 48c. When the tube is crushed, the tube 20 is supported by a pair of support rods 50 and 50 immediately above the tube 20 to prevent displacement.
[0025]
Note that the fixing member 48 can be used by being disposed in an extraction mechanism 52 having a structure different from the extraction mechanism 10 according to the above-described embodiment. As shown in FIGS. 7 to 9, the other dispensing mechanism 52 includes an actuator 56 such as a solenoid inside the frame 13, and a plunger 54 protruding forward is fixed to the frame 13. It extends forward through the insertion hole 48 b of the member 48. A pressing body 58 made of synthetic resin or hard rubber is disposed at the tip of the plunger 54, and a spring 60 is elastically disposed between the pressing body 58 and the substrate portion 48c of the fixing member 48. The pressing body 58 is always close to the pressing portion 66 of the lid portion 62 having the same configuration as described above, which is disposed on the frame 13 via the hinge 64, and the discharging tube 20 is pressed by both 58 and 66. It is configured to crush and regulate the dispensing of beverages.
[0026]
In the state described above, when the actuator 56 is biased, the plunger 54 moves backward toward the body of the actuator 56 against the elasticity of the spring 60. As a result, the pressing force on the dispensing tube 20 is released, and the beverage is dispensed from the tube 20 (see FIG. 9). Then, when the bias of the actuator 56 is released at the timing when the dispensing of the beverage is finished, as shown in FIG. 9, the pressing body 58 is moved toward the pressing portion 66 by the elasticity of the spring 26, and the dispensing tube Squeeze 20 to regulate the dispensing of beverage. At this time, since the movement of the extraction tube 20 in the left-right direction is restricted by the support rods 50 and 50 immediately above the pressing portion by the pressing body 58 and the pressing portion 66, the extraction tube 20 is pressed by the pressing body. It can press reliably between 58 and the press part 66, and can prevent a drink leak.
[0027]
【The invention's effect】
As described above, in the dispensing mechanism of the beverage dispensing device according to the present invention, the pressing body that presses the dispensing tube between the pressing portion and the presser lever is used for the biasing means by the lever principle. Since it is configured to move against the urging force, the pressing force required to rotate the lever can be reduced, and the dispensing operation can be performed easily. Further, since the pressing body moves while being guided by the support base, the pressing body can move stably. Further, since the engaging portion that supports the dispensing tube is provided above the pressing body, the displacement of the tube is prevented, and the dispensing tube is reliably pressed and crushed by the pressing portion and the pressing body. And can prevent beverage leakage. Furthermore, in the pouring mechanism, when the pouring lever is rotated, the contact position between the pouring lever and the pivoting member is the distance from the axis of the support shaft to the point of action and the point of action from the point of contact. Therefore, even if the urging means is compressed and the elasticity of the urging means gradually increases, the pressing force required to rotate the dispensing lever is small. A certain amount of power is sufficient, and the dispensing work can be performed easily.
