- ST for example, 8 ° C.
- the liquid temperature exceeds the set temperature ST during the pouring operation period for one drinking container 40, but this is because the drinking container 40 is, for example, a plurality of intermittent cups of a mug. This corresponds to an example in which the liquid is poured out, and when the liquid alone is poured into only one mug, it is not normal that the liquid temperature reaches the set temperature ST during the pouring operation period.
- the liquid temperature during the pouring operation period is the set temperature ST even in the case of single pouring only It can occur that
- the temperature of the raised cooling water 55 starts to decrease due to the end of the pouring of the liquid 20 from the pouring device 50. Along with this, as shown in FIG. 3A, the temperature of the liquid to be measured also becomes dull and stops, and the liquid temperature also falls. Therefore, in the example shown in FIG. 3A, the liquid temperature to be measured becomes equal to or higher than the set temperature ST in the period from time t2 to time t4.

Even if the integrated flow rate from time t2 to time t3 is less than the determination value, the determination unit 130 determines that the cooling capacity of the pouring device 50 is sufficient and appropriate.
- the above-mentioned method is an example about the processing method in Step S15, and it is not limited to this.
- the determination operation is performed for each drinkable container 40 for one cup, but, for example, the determination unit using time information generated by the time information generation unit 131 of the determination unit 130 In 130, the integrated flow rate corresponding to the set time may be determined and compared with the determination value.

Abstract
Description
このようにしてビール樽内のビールは、顧客へ提供される。
即ち、本発明の一態様における液体品質管理装置は、貯蔵容器内の液体を、加圧により供給管を通して注出装置へ供給して冷却を行い、該注出装置から飲用容器へ注出する液体供給システムに付加可能な液体品質管理装置であって、
上記飲用容器へ注出される液体量を検出する流量センサを有し、上記注出装置から飲用容器へ注出した液体の実測流量を求める実流量作成部と、
上記飲用容器へ注出される液体の温度を計測する注出液体温度センサと、
上記実流量作成部及び上記注出液体温度センサと電気的に接続された判定部であって、計測された液体温度が設定温度以上である期間中に上記飲用容器に注出された流量の積算流量を求め、該積算流量と判断値との比較によって上記注出装置における冷却能力の適否を判定する判定部と、
を備えたことを特徴とする。
このように、当該液体品質管理装置によれば、使用状況に見合った冷却能力を有する注出装置の選定が可能になる。
液体品質管理装置101は、注出装置50(ビールディスペンサー50)における、本実施形態では冷却能力の良否を、より詳しくは、飲用容器40へ注出される液体20の流体量に対する当該注出装置50の冷却能力の適否を判定可能にし、注出される液体20の品質維持を可能にする装置である。
このような液体品質管理装置101は、図1に示すように基本構成として、実流量作成部110と、注出液体温度センサ120と、判定部130とを備える。これらの基本構成に加えて液体品質管理装置101は、図2に示すようにさらに、警告部140、表示装置141、送受信部150、及び流体流路調整装置170を備えることができる。
これらの構成部分について、以下に順次説明を行う。
流量センサ111は、実施形態では、貯蔵容器10の出口とビールディスペンサー50との間の適所において、供給管30を通過するビールを挟むように設置されている。尚、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。流量センサ111として、本実施形態では超音波センサを用いる。
このような判定部130は、上記時刻情報を用いて、注出液体温度センサ120で計測された液体20(本実施形態ではビール)の温度が設定温度(本実施形態では一例として8℃)以上である期間中に、実流量作成部110から得られた実測流量を基に、飲用容器40に注出された液体(ビール)20の積算流量を求める。さらに判定部130は、求めた積算流量と、予め設定した判断値(流量値)とを比較することで注出装置50における冷却能力の適否を判定する。
尚、このような冷却能力の適否判定動作を含む判定部130の動作は、図5を参照して追って詳しく述べる。
さらにまた判定部130は、詳細後述する合算値作成部134(図2)を有することもできる。
流体流路調整装置170は、本願出願人による例えば特許5649801号に開示されるような装置であり、供給管30に設置されて、液体注出口54から飲用容器40へのビール(液体20)注出を停止する装置である。また流体流路調整装置170は、例えば、液体20の注出中に、貯蔵容器10内のビールが無くなったとき(貯蔵容器10が空になったとき)、また貯蔵容器10を交換する際に、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こともできる。
また判定部130による作動制御において、流体ストッパ装置1710は、送受信部150で受信した情報に応じて、判定部130により作動が制御されることも可能である。
注出装置(ビールディスペンサー)50におけるレバー56の店スタッフによる操作により、液体(ビール)20が飲用容器40に注出される。その注出量は、実流量作成部110で求められ、実測流量として判定部130へ供給される。
また、図3A、図3B、図3C、及び図4において、黒帯は、例えばコップ、ジョッキ、ピッチャー等の飲用容器40の1杯分への液体20の注出動作期間を示している。
上述したように、液体注出口54におけるレバー56の操作により、加圧源15にて圧送される液体(ビール)20は、液体冷却管52内を通過し、冷却水55との熱交換により冷却されて飲用容器40へ注出される。本実施形態のように、注出液体温度センサ120が冷却水55内に設置されている状態においては、注出液体温度センサ120で計測される液体20の温度は、例えば図3Aに示すように変化する。
尚、図3Aでは、1杯の飲用容器40への注出動作期間中に、液体温度が設定温度STを超えているが、これは、飲用容器40が例えばジョッキで複数杯分の断続的な注出が行われた場合の例に相当し、ジョッキ1杯のみへ単独的に注出を行った場合に、注出動作期間中に液体温度が設定温度STに達することは通常生じない。但し、例えばピッチャーのようなコップあるいはジョッキ等の飲用容器40に比べて容量が大きい飲用容器40の場合には、1杯のみの単独的注出でも注出動作期間中に液体温度が設定温度STに達することは生じ得る。
図5のステップS11では、判定部130は、注出液体温度センサ120で計測された液体温度が設定温度STに達したか否かを判断する。尚、設定温度STは、上述の例えば8℃に設定可能である。設定温度STに達した時点で、上の例では時刻t2で、判定部130は、次のステップS12にて、実流量作成部110から供給されているΔt時間毎の液体量の積算を開始する。以後、次のステップS13の判断時点まで、判定部130は、液体量の積算を継続する。
図3Aに示すように、時刻t2以後、液体20の注出動作が、上記時刻t4以前の時刻t3で終了したとすると、つまり1杯分の飲用容器40に対する注出動作が時刻t3にて終了したとすると、判定部130は、時刻t2から時刻t3まで、液体量の積算を継続し、その積算流量を求める(ステップS14)。既に説明したように、注出動作の終了は、開始も含めて流量センサ111の検出信号の有無によって判断できる。また、上述のように注出動作の終了により積算流量が決定され、決定後、判定部130は、求めた積算流量をリセットし、次の積算動作に備える。
即ち、次のステップS16に示すように、合算値作成部134は、流量センサ111で測定された、設定温度ST未満の液体20の流量について、設定期間に含まれる流量を合算して合算値を求め、該合算値が予め設定していた既定値未満である場合には、判定部130は、当該注出装置50の冷却能力は、過剰であると判定する。一方、積算流量が判断値未満である状態において、合算値が既定値以上である場合には、判定部130は、当該注出装置50の冷却能力は充足しており適正であると判断する。
判定部130によって、液体(ビール)20の温度が設定温度ST以上にある期間中に1杯分の飲用容器40に対して注出された液体20の積算流量と、判断値との比較が行われ、この比較結果から注出装置(ビールディスペンサー)50における冷却能力の適否を判断することが可能になる。よって、注出される液体20の品質管理が可能になる。
よって通信回線160に接続している、例えばビールメーカー側の分析装置200(コンピュータ)は、各飲食店等から、例えば上記付加価値警告情報を得ることが可能である。したがって、ビールメーカー側では、各飲食店等におけるビール20の連続的な注出操作時(換言すると繁忙時)に対応した冷却能力を有するビールディスペンサー50を選定し、推薦することが可能になる。一方、ビールディスペンサー50が過剰な冷却能力を有すると判断することもでき、当該液体品質管理装置101によれば、注出装置50の使用状況に見合った冷却能力を有する注出装置50の選定が可能になる。
したがって、液体20の注出を停止したにもかかわらず、計測される液体温度が下降に転じない状況が検知された場合には、冷凍機53、冷却水55を撹拌するために設けた撹拌装置等の故障、と判断することも可能である。
又、2017年12月11日に出願された、日本国特許出願No.特願2017-236783号の明細書、図面、特許請求の範囲、及び要約書の開示内容の全ては、参考として本明細書中に編入されるものである。
