飲料の流路として弾性変形可能な可撓部を有するチューブを使用して飲料を注出する方法であって、
前記可撓部の内腔を第1の断面積を有する第1の状態に設定して、前記チューブを通じて前記飲料を注出し、
前記可撓部の内腔を、第1の断面積を有する第1の状態から、前記第1の断面積よりも小さな第2の断面積を有する第2の状態に設定して、前記チューブ内を流れる前記飲料から泡を生成することを特徴とする。
図1は、実施形態に係る飲料注出装置(以下、「注出装置」という。)1の概略構成を示す。飲料注出装置1は、例えば、飲料を収容した飲料貯蔵容器を内部に格納して冷却することが可能な空冷機、又は内部を通過する飲料を急速冷却することが可能な瞬冷機等の外壁面や上部に設けられたタワー等に設置することができる。
第1の弁ユニット31は、チューブ内腔33の断面を開放状態である非変形状態(第1の状態)と閉鎖状態である変形状態(第2の状態)との間で切り換える、飲料注出用の装置又は機構である。開放状態は、チューブ12に外部から力が加えられておらず、飲料20を輸送可能な状態である。閉鎖状態は、チューブ12に外部から力が加えられて内腔33が完全に閉じられ、飲料の流れが阻止された状態である。
第2の弁ユニット32は、チューブ内腔33の断面を非縮小状態である非変形状態(非縮小状態)(第1の状態)[図2参照]と変形状態(縮小状態)(第2の状態)[図4参照]との間で切り換える、泡付け用の装置又は機構である。非縮小状態は、チューブ12に外部から力が加えられておらず、飲料20を輸送可能な状態である。したがって、非縮小状態は、第1の弁ユニット31の開放状態と実質的に同じである。縮小状態は、チューブ12に外部から力が加えられて内腔33の断面が縮小された状態で、縮小された内腔断面を通過する飲料20が、該縮小された内腔断面を通過する際に加圧されて炭酸ガスが過剰に溶け込み、縮小された内腔断面を通過後に減圧されて、飲料20に溶けた炭酸ガスが泡になる。
上述したソレノイド39,45は、制御部47に接続されており、制御部47から出力される信号に基づいて動作する。注出装置1はまた、飲料20を注出する際にユーザが操作する操作部48を備えており、操作部48を通じて制御部47に入力される信号に基づいて、以下に説明する動作を実行する。操作部48は、飲料が注出されない状態、飲料が注出される状態及び泡が注出される状態(泡付け状態)の3つの状態に切り換えるスイッチ49を備えている。
以上の構成を備えた飲料注出装置1の動作を簡単に説明する。
飲料注出前の待機状態では、制御部47は第1の弁ユニット31のプル型ソレノイド39と第2の弁ユニット32のプッシュ型ソレノイド45を共にオフ状態(非通電状態)に保つ。これにより、第1の弁ユニット31の上ブロック37は固定ブロック37に接近した進出位置(図1に示す点線位置)をとり、チューブ内腔33の断面を閉鎖して飲料20の流れを遮断する。一方、第2の弁ブロック32のプッシュ型ソレノイド45はチューブ12から離れて退避位置(図1に示す実線位置)をとり、チューブ内腔33の断面を非縮小状態に保つ。なお、待機状態においても、樽21及びチューブ12内の飲料に常圧(0.1MPa)以上の圧力、例えば0.15MPa~0.3MPaの圧力がかかるようにすることが好ましい。これにより、第1の弁ユニット等から空気がチューブ12内に混入するのを防止することができ、さらに飲料中の炭酸ガスが抜けることを防ぐことができる。例えば、空冷機を使用し、樽21内の飲料20の温度が15℃以下に調整する場合、飲料に加わる圧力は0.1~0.2MPaとすることが好ましい。瞬冷機を使用し、樽21内の飲料20の温度を15℃以上に調整する場合、飲料に加わる圧力は0.2~0.3MPaとすることが好ましい。このように圧力が加わることで、例えば自由状態(内腔に圧力が加わっていない状態)で外径5.0mm、内径3.0mmのシリコンチューブは、外径が約6.5mm、内径が約5.15mmになる。
飲料注出時、ユーザが操作部48のスイッチ49を操作して飲料を注出する状態を選択すると、操作部48から出力される起動信号に基づいて、制御部47は、第1の弁ユニット31のプル型ソレノイド39をオン状態(通電状態)に切り換え、第2の弁ユニット32のプッシュ型ソレノイド45をオフ状態(非通電状態)に維持する。これにより、第1の弁ユニット31の上ブロック37は下ブロック36及びチューブ12から離れた退避位置(図1に示す実線位置)に移動し、チューブ内腔33を開放状態に切り換える。一方、第2の弁ユニット32の上ブロック43は退避位置に維持され、チューブ内腔33の断面が非縮小状態に維持される。これにより、樽21内の飲料20は、飲料注出管22とチューブ12を介して、ノズル13から注出される。
所定量の飲料が注出された後、ユーザが操作部48のスイッチ49を操作して泡付け状態を選択すると、操作部48から出力される泡付け開始信号に基づいて、制御部47は、第1の弁ユニット31のプル型ソレノイド39をオン状態(通電状態)に切り換え、さらに第2の弁ユニット32のプッシュ型ソレノイド45もオン状態(通電状態)に切り換える。これにより、第1の弁ユニット31の上ブロック37は下ブロック36及びチューブ12から離れた退避位置(図1に示す実線位置)に移動し、チューブ内腔33を開放状態に切り換える。一方、第2の弁ユニット32の上ブロック43は退避位置から進出位置(図1に示す点線位置)に移動し、チューブ12を押圧してチューブ内腔33の断面を縮小する。これにより、チューブ12を通じて送られる飲料20は、縮小されたチューブ内腔33の断面を通過する際に加圧されて、炭酸ガスが過剰に溶け込み、縮小された内腔断面を通過後に減圧されて、飲料20に溶け込んでいた炭酸ガスが泡になる。その後、泡はノズル13を介して、すでに注出された飲料の上に注出され、これにより泡付けされた飲料が得られる。このように、泡付け時、チューブ12は飲料泡化路を形成する。
第2の弁ユニット32、特に、下ブロック42と上ブロック43の構成と動作を説明する。
例えば、第1の弁ユニット31に関して、上述の説明では、開放状態において上ブロック(可動ブロック)37はチューブ12の上方に退避してチューブ12に非接触の状態に保つものとしたが、上ブロック37は退避位置においてチューブ12の外周面に接触していてもよいし、注出される飲料20の品質に影響を与えない範囲でチューブ12に接触して該チューブ12を変形させていてもよい。同様に、第2の弁ユニット32に関して、上述の説明では、非変形状態において上ブロック43はチューブ12の上方に退避してチューブ12に非接触の状態に保つものとしたが、上ブロック43は退避位置においてチューブ12の外周面に接触していてもよいし、注出される飲料20の品質に影響を与えない範囲でチューブ12に接触して該チューブ12を変形させていてもよい。
上述の説明では、第1の弁ユニット31において、上ブロック(可動ブロック)37を下ブロック(固定ブロック)36の上に配置したが、上ブロックを下ブロックの下に配置してもよい。同様に、上述の説明では、第2の弁ユニット32において、上ブロック(可動ブロック)43を下ブロック(固定ブロック)42の上に配置したが、上述した形の上ブロック43を上述した形の下ブロック42の下に配置してもよい。
上述の説明では、第1の弁ユニット31において、上ブロック37を可動にして、下ブロック36を固定したが、上ブロック37を固定して、下ブロック36を可動にしてもよい。この場合、下ブロック36にソレノイドが連結される。同様に、上述の説明では、第2の弁ユニット32において、上ブロック43を可動にして、下ブロック42を固定したが、上ブロック43を固定して、下ブロック42を可動にしてもよい。
上述の説明では、第2の弁ユニット32において、下ブロック42に左壁53と右壁54(一対の側壁)を設けたが、上ブロック43に一対の側壁を設けることもできる。
上述の説明では、第1の弁ユニット31にプル型ソレノイドを採用し、第2の弁ユニット32にプッシュ型ソレノイドを採用したが、第1の弁ユニットにプッシュ型ソレノイドを採用し、第2の弁ユニットにプル型弁ユニットを採用してもよい。例えば、上述の実施形態のように、上ブロック37を可動ブロック、下ブロック36を固定ブロックにする場合、第1の弁ユニットではプッシュ型ソレノイドを下ブロックの下方に配置し、第2の弁ユニットではプル型ソレノイドを上ブロックに配置する。
上述の説明では、第1の弁ユニット31にプル型ソレノイドを用い、第2の弁ユニットにプッシュ型ソレノイドを用いたが、両弁ユニットに同じ型(プル型、プッシュ型)のソレノイドを採用してもよい。この場合、例えば、第1の弁ユニット31では上述のように上ブロックの上方にプル型ソレノイドを配置し、第2の弁ユニットでは下ブロックの下方にプル型ソレノイドを配置するか、第1の弁ユニット31では下ブロックの下方にプッシュ型ソレノイドを配置し、第2の弁ユニットでは上述のように上ブロックの上方にプッシュ型ソレノイドを配置する。
上述の説明では、第1及び第2の弁ユニット31、32にそれぞれソレノイドを設けたが、例えば一つの両用型ソレノイドを採用し、プランジャの一端を第1の弁ユニット31の可動ブロックに駆動連結し、プランジャの他端を第2の弁ユニット32の可動ブロックに駆動連結してもよい。この形態によれば、一つのソレノイドで両弁ユニットを同時に操作できる。
以上の実施形態及び変形形態では、チューブ12を水平方向に配置し、そのチューブ水平部分を圧し潰すものとしたが、鉛直方向又は斜め方向に配置されたチューブ部分を圧し潰してもよい。また、以上の実施形態及び変形形態では、飲料輸送チューブの全体を弾性材料で形成したが、少なくとも第1の弁ユニット31と第2の弁ユニット32によって加圧変形される部分を弾性材料の可撓部とし、その他の部分は非弾性材料としてもよい。
以上の実施形態及び変形形態では、第1及び第2の弁ユニット31、32の駆動部38,44にそれぞれ駆動源としてソレノイドを設けたが、これらのソレノイドの少なくとも一方を、その他のアクチュエータやモータに代えてもよい。駆動源にモータを用いる場合、モータと可動ブロックとの間には例えば歯車機構(例えば、ラック・アンド・ピニオン)を設け、この歯車機構を介してモータの回転運動を直線運動に変換することが好ましい。ただし、駆動源及び駆動伝達機構はこれらの実施形態に限るものではない。
以上の実施形態及び変形形態では、操作部にスイッチを設け、該スイッチから出力される信号に基づいてソレノイド又はモータを駆動して、注出装置を3つの状態(待機状態(非注出状態)、飲料注出状態、泡付け状態)に切り換えるものとしたが、タッピングハンドル(操作レバー)の位置を手動で切り換えることによって飲料を注出する装置では、タッピングハンドルと可動ブロックを機械的に連結し、タッピングハンドルのポジションに応じて2つの可動ブロックを切り換えるようにしてもよいし、タッピングハンドルのポジションを検出器で検出し、検出器の出力に基づいてソレノイド又はモータを駆動して2つの可動ブロックを切り換えるようにしてもよい。
以上の実施形態及び変形形態では、第2の弁ユニット32において、チューブ12の左右端部を押圧するように、上ブロック43と下ブロック42の形状が決定されているが、必ずしもチューブ12の左右端部を押圧するようにする必要はなく、チューブ12の一部のみを押圧するように上ブロック43と下ブロック42の形状を決定すればよい。例えば、チューブ12の左側又は右側のみを押圧するようにしてもよく、この場合、例えば、上ブロックの左側又は右側のみに突出部を設けることができる。この構成によっても、押圧機構の作動誤差が生じたり、チューブの寸法誤差があったとしても、流路を完全に塞ぐことがなく、チューブ12の内腔断面積の変動を最小限に抑えることが可能となるが、上述した実施形態に比べ、押圧時にチューブ12を最適な位置に位置付けすることが困難となる。
