上記液体供給システムは、貯蔵容器内の飲料を、加圧により供給管を通して注出装置へ供給し該注出装置の注出口から飲用容器へ注出するシステムであり、貯蔵容器の出口から注出口までの飲用流体管内の洗浄作業の有無情報、及び貯蔵容器内飲料の温度情報について、通信部を介して上記管理サーバーと通信を行い、
上記管理サーバーは、上記洗浄作業の有無情報、上記温度情報、及び飲料の液種情報を元に、上記貯蔵容器の出口から上記注出口までの飲用流体管内の汚れ予測を出力する、
ことを特徴とする。
図1に示すように、このような飲用流体管内汚れ予測システム500は、液体供給システム100と、管理サーバー300とを備え、さらに、洗浄度判定装置200及び販売情報管理システム400を備えることができる。
液体供給システム100及び販売情報管理システム400は、それぞれ通信回線550を介して管理サーバー300と接続され、洗浄度判定装置200は、例えば近距離無線通信機能560を介して液体供給システム100と接続される。
各機器について、順次、以下に詳しく説明していく。
このような液体供給システム100は、貯蔵容器10内の飲料(例えばビール)20を、加圧源15による加圧によって供給管30を通して注出装置50へ供給つまり圧送し、注出装置50から飲用容器(例えばジョッキ)40へ注ぎ出すシステムである。ここで貯蔵容器10は、例えばビールメーカーにてビールが充填された、いわゆるビール樽と呼ばれるステンレス製容器であり、例えば5L、10L、19L等の内容量のものがある。加圧源15は、炭酸ガスボンベである。供給管30は、貯蔵容器10と注出装置50との間でビールの通液を可能にする、可撓性を有する例えばポリアミド、ポリウレタン、ポリエステル等製の樹脂チューブである。供給管30から注出装置50における液体注出口54に至るまで、流体の通液管路の内径は、通液管路内のスポンジ洗浄を容易にするため全て同寸法にて設計されているのが好ましい。
ここで水洗浄作業は、供給管30を通過する液体をビールから洗浄水に切り換え、洗浄水を圧送することで行う。この水洗浄作業によって、営業終了時において貯蔵容器10の出口から注出口54間の飲用流体管内に残存していたビールは、洗浄水に置換されながら注出口54から排出される。
このようにして水洗浄が行われた後、次のビール提供の準備として、貯蔵容器10の出口から注出口54間の飲用流体管内に存在する洗浄水は、管内に炭酸ガスを吹き込むことにより炭酸ガスで置換され、飲用流体管内は、空液状態にされる。これらの一連の動作にて、水洗浄動作が終了する。よって、水洗浄作業終了時点では、貯蔵容器10から注出口54間の飲用流体管内は、空液状態になっている。
即ち、本出願人は、液体供給システム100に設置可能である、例えば特許5649801号に開示されるような流体流路調整装置を提供している。該流体流路調整装置は、供給管30に設置され、注出口54から飲用容器40へのビール注出中に、貯蔵容器10内のビールが無くなったときに(貯蔵容器10が空になったとき)、あるいはまた、貯蔵容器10を交換するときに、注出装置50の液体注出口54から加圧気体である炭酸ガスが噴出するのを防止する装置である。この目的達成のため、供給管30内を通過する流体状態の判断用として、該流体流路調整装置は、発光素子及び受光素子を有する液体状態判断部を設けている。よって、この流体流路調整装置を洗浄モード検知部110として利用することも可能である。
このような水洗浄作業の有無に関する情報は、貯蔵容器10の出口から注出口54までの飲用流体管内の汚れ予測に対して直接に関係し、最も重要なファクターである。
尚、液種センサ131の設置位置はこれに限定されず、例えば注出装置50における供給管30に取り付けられてもよい。また、設置した場合には、液種センサ131による検出情報は、通信部140へ送出される。
本実施形態における洗浄度判定装置200は、上述した液体供給システム100から採取したスポンジ洗浄水を被測定液体とし、該洗浄水の濁度を測定し、さらには、その測定結果から液体供給システム100における洗浄作業の良否を判定し、これらの情報を管理サーバー300へ供給するものである。
以下には、測定器210及びサンプリング容器230について説明を行う。
サンプリング容器230は、装着部212に対して着脱可能に装着されるコップ形状の容器であり、投光素子221及び受光素子222による投受光が可能なように透光性の素材、例えば樹脂材あるいはガラス材等にて成型された容器である。このようなサンプリング容器230は、下部に液体収納部231を有し上部の開口にバスケット234が着脱可能な内側容器231aと、液体収納部231を包囲する大きさを有する外側容器232aとを有する。液体収納部231は、被測定液体であるスポンジ洗浄水を既定量(一例として約50ml-80ml)収納する。サンプリング容器230が装着部212に装着されたとき、この液体収納部231を直径方向212bに沿って光路224が位置する。また、液体収納部231における結露防止のため、液体収納部231の周囲を外側容器232aで密閉し空気層232を設けた二重構造を有する。一方、液体収納部231に収納される被測定液体が結露を発生させない液温である場合には、サンプリング容器230は、結露防止構造を有しない構造であってもよい。また、外側容器232aの周面には、装着部212における装着部側位置決め部2127に係合可能な容器側位置決め部236を突設している。また、バスケット234は、スポンジ洗浄水と共に飲用流体管から排出されるスポンジを受け止める、いわゆる「ざる」として機能する。
濁度測定処理において、被測定液体の濁り具合と、受光素子222の出力信号(換言すると受光素子222における受光量)とは、ほぼ比例関係を有する。よって、一例として、予め求め格納している、受光素子222の出力信号の大きさと濁度との関係情報から、制御部214は、濁度測定結果を求めることができる。さらに一例として、予め求め格納している、濁度測定結果と洗浄度判定用基準値とを比較することで、制御部214は、洗浄作業の良否判断を行うことができる。
スイッチ部218として、本実施形態では、電源(オン/オフ)用、測定用、及び校正用の3つの押下スイッチを表面211に設けている。
ステップS1、S2にて、洗浄度判定装置200のスイッチ部218における電源スイッチを押下し、洗浄度判定装置200を起動する。
次にステップS3では、スポンジ洗浄に使用する水道水(原水)をサンプリング容器230の液体収納部231に採取し、当該サンプリング容器230を測定器210の装着部212に装填して校正作業を行う。該校正作業は、洗浄度判定装置200のスイッチ部218における校正ボタンの押下により、制御部214にて、受光素子222の出力信号の大きさと濁度との関係情報(検量線)の校正が自動的に行われる。尚、ステップS3をスキップして、次のステップS4へ進むこともできる。
また制御部214は、求めた濁度値と、飲用流体管の洗浄作業の良否を判断するための既定の洗浄度判定用基準値とを比較し、洗浄作業の良否判断を行う。
さらにまた制御部214は、スポンジ洗浄水(被測定液体)の濁度測定に関する情報、例えば濁度測定結果、洗浄度判定結果、校正の有無及び校正値、環境温度、測定日時、等の情報を記憶部214dに格納する。
以上にて、測定動作(ステップS4)は終了する。
送信部250は、制御部214にて得られた上述の各種情報のうち、少なくとも濁度測定結果の情報を、例えば近距離無線通信機能560を介して液体供給システム100の通信部140へ送出する。そして通信部140は、通信回線550を介して管理サーバー300へ、例えば時刻情報及び店舗情報を含む他の情報と共に濁度測定結果の情報を送信する。
洗浄度判定装置200の送信部250は、通信回線550を介して直接に管理サーバー300と通信するように構成可能であるが、この場合、洗浄度判定装置200は携帯可能物であることから、少なくとも店舗情報の入力を要することになる。よって、各店舗における液体供給システム100と通信を行う方の利便性が高い。
また、近距離無線通信機能560及び通信回線550を介さずに、上述の各種情報のうち、少なくとも濁度測定結果の情報を、作業者が管理サーバー300に直接、入力してもよい。
販売情報管理システム400は、上述したようにPOSシステムに相当するシステムであり、顧客の料金支払い等の際に販売情報等を取り込み、飲料20の、例えば、一販売あたりの規定容量である販売単位容量、販売量、及び販売時刻などの各情報を関連付けた販売情報を、通信回線550を介して管理サーバー300へ供給する。ここで、上述の「一販売あたりの規定容量」つまり「販売単位容量」とは、例えば、それぞれの大きさの飲用容器40についてそれぞれ定めた、1杯分の容量が相当し、例えば中ジョッキであれば300ml、大ジョッキであれば500ml、等の値が相当する。この販売単位容量は、販売情報管理システム400からの入力によって、あるいはまた、管理サーバー300において、例えば消費量分析部等の機能部分を有する場合にはそこへの入力によって、設定可能であり、複数種の飲用容器40に対してそれぞれ設定可能である。
管理サーバー300は、機械学習部を有しており、通信回線550を介して上述の少なくとも液体供給システム100から供給される各種情報に基づいて、店舗毎の液体供給システム100における貯蔵容器10の出口から注出口54までの飲用流体管内の汚れを機械学習によって、店舗毎に予測する。
また管理サーバー300は、さらに、液体供給システム100から濁度測定結果の情報、及び、販売情報管理システム400から通信回線550を介して供給される情報の少なくとも一方も加えて上記管内の汚れを機械学習によって、店舗毎に予測する。
出力となる汚れ予測としては、例えば、飲用流体管内の汚れがしきいレベル(図4FのしきいレベルLth)を超えるまでの日数等の時間情報の提示、しきいレベルLthに対して現時点の汚れレベルが何%程度であるかの提示、等が挙げられる。
このような時間情報等と、汚れレベルとの関係が実験段階(実験室)で得ることができ、これを上記オリジナル教師モデルとすることができる。
また、上述の洗浄作業の有無に関する情報には、既に説明した、前回洗浄から今回の洗浄作業までの経過時間情報(上述のt1、t2時間に相当)も含むことができる。
以上を踏まえ、以下に図4Aを参照して管理サーバー300の説明を行う。
また、各店舗において、洗浄度判定装置200から液体供給システム100へ、液体供給システム100におけるスポンジ洗浄水の濁度測定結果の情報が送出された場合には、情報取得部310は、濁度測定結果の情報も取得する。
さらにまた、店舗が販売情報管理システム400を導入している場合には、情報取得部310は、販売情報管理システム400が送出する上述の販売情報を、時刻情報及び店舗情報を含む他の情報と共に取得する。
さらにまた上述したように、学習処理部340は、オリジナル教師モデル341を基に処理された学習済モデル322に対しても、少なくとも上述の3つの情報にて学習処理を行う。
ステップS11では、学習処理部340は、上述のオリジナル教師モデル341に対して学習処理を施す。該オリジナル教師モデル341は、店舗毎に生成される学習済モデル322のベースとなるモデルであり、学習処理部340における記憶部に格納される。また、オリジナル教師モデル341に対する学習処理は、既知の手法と同様である。学習処理部340は、オリジナル教師モデル341が正解の汚れレベルを出力するように、既知の手法にてパラメータ(重み係数、及びバイアス等)の修正が行われる。また、店舗毎の学習済モデル322において、各パラメータは、通常、店舗毎に異なっている。
また、学習処理部340は、上述したように、生成した各店舗の学習済モデル322に対しても、各店舗からさらに取得されてくる各種情報によって、学習処理を行う。
学習済モデル322は、このような学習処理によって、より良好な汚れ予測を出力し得るように学習処理される。そして上述のように、それぞれの店舗毎に学習済モデル322が生成され、店舗毎に各学習済モデル322がカスタマイズされていく。
また、上述した各機能の一部又は全部は、CPU361による処理に代えて、又は、これと共に、DSPによる処理によって実現されてもよい。又、同様に、各機能の一部又は全部は、ソフトウェアによる処理に代えて、又は、これと共に、専用のハードウェア回路による処理によって実現されてもよい。
このような学習済モデル322としては、例えば、ニューラルネットワーク、回帰木、SVM(Support Vector Machine)、ベイズ識別器、又、これらのアンサンブルモデル等、任意の学習器を用いることができる。尚、当該学習済モデル322として、いわゆるディープラーニングが適用されるものであってもよい。
既に述べたが、濁度測定は、スポンジ洗浄水の他、水道水による水洗浄の洗浄水に対して行ってもよい。そして、水洗浄の洗浄水の濁度測定情報を管内の汚れレベルの補正用として使用してもよい。
本実施形態における学習済モデル322は、入力層として、上述の洗浄作業有無情報等を入力するための複数の入力ユニットを有している。複数の入力ユニットXi-Xkは、上述の洗浄作業有無情報、液温情報、液種情報、さらに、洗浄作業の頻度情報、スポンジ洗浄水の濁度情報、及び販売情報等の入力を受け付ける構成となっている。
尚、上述の学習済モデル322の構成は、一例であって、種々に変更されてよい。
既に説明したように、汚れ予測システム500における管理サーバー300には、それぞれの店舗における各液体供給システム100から、年月日時分の時刻情報と共に、洗浄作業の有無情報、及び貯蔵容器10内の飲料20の温度情報が少なくとも供給され、さらにまた、洗浄水(スポンジ洗浄あるいは水洗浄によるもの)の濁度情報が供給されるときもある(ステップS20)。ここで、飲料20の液種情報は、管理サーバー300に入力されている。
よって、販売情報を取得することで、さらに高いレベルでの飲用流体管内の汚れ管理が可能となる。
本発明は、添付図面を参照しながら好ましい実施形態に関連して充分に記載されているが、この技術の熟練した人々にとっては種々の変形や修正は明白である。そのような変形や修正は、添付した請求の範囲による本発明の範囲から外れない限りにおいて、その中に含まれると理解されるべきである。
