Carbonate (carbonated water production device) that produces carbonated water by being immersed in the cooling water, 23 is a carbonated water flow meter for measuring carbonated water flow, 24 is a carbonated water solenoid valve, 30 is a stock solution supply line, and 31 is Carbon dioxide gas cylinder, 32 is a stock solution tank, 33 is a stock solution cooling coil that cools the stock solution that is immersed in the cooling water stored in the cooling water tank, 34 is a stock solution flow meter for measuring the stock solution flow rate, and 36 is a stock solution solenoid valve It is. A plurality of stock solution supply lines 30, a stock solution tank 32, a stock solution cooling coil 33, a stock solution flow meter 34, and a stock solution solenoid valve 36 are provided corresponding to the number of types of beverages to be supplied. The stock solution supply pipe 30 is provided, and the stock solution flow meters 34a, 34b, 34c, 34d, and the stock solution solenoid valves 36a, 36b, 36c, 36d are provided (some are not shown).
そして、制御部により、水ポンプ１２が運転され、水入口電磁弁１１、冷水電磁弁１５が開放されると、水ポンプ１２で飲用水が圧送され、水入口電磁弁１１から水冷却コイル１３、冷水流量計１４、冷水電磁弁１５を通流し、水冷却コイル１３で冷やされて冷水供給管路１０から飲料吐出ノズル１６に冷水が供給される。そして、冷水流量計１４が出力するパルスが予め設定してあるパルス数に達すると、制御部が水ポンプ１２の運転を停止すると同時に、水入口電磁弁１１、冷水電磁弁１５を閉塞して冷水の供給を停止する。 And if the water pump 12 is drive | operated by the control part and the water inlet solenoid valve 11 and the cold water solenoid valve 15 are open | released, drinking water will be pumped by the water pump 12, the water cooling coil 13 from the water inlet solenoid valve 11, The chilled water flow meter 14 and the chilled water electromagnetic valve 15 are passed through, cooled by the water cooling coil 13, and chilled water is supplied from the chilled water supply pipe 10 to the beverage discharge nozzle 16. When the number of pulses output from the chilled water flow meter 14 reaches a preset number of pulses, the control unit stops the operation of the water pump 12 and simultaneously closes the water inlet solenoid valve 11 and the chilled water solenoid valve 15 to chill water. Stop supplying.
また、冷水供給管路１０を分岐させ、カーボネータ給水電磁弁２１を介してカーボネータ２２に接続している。カーボネータ２２内には、水位を検出するためのフロートスイッチ（図示せず）が設けられ、水位が下限位置になると、水入口電磁弁１１、カーボネータ給水電磁弁２１を開き、水ポンプ１２を運転させて水冷却コイル１３で冷やされた冷水をカーボネータ２２に供給し、水位が上限位置になると、水入口電磁弁１１、カーボネータ給水電磁弁２１を閉じて水ポンプ１２の運転を停止する。そして、炭酸ガスボンベ３１から供給される炭酸ガスを冷水に溶かし込んで炭酸水を製造する。 Further, the cold water supply pipe 10 is branched and connected to the carbonator 22 via the carbonator water supply electromagnetic valve 21. A float switch (not shown) for detecting the water level is provided in the carbonator 22, and when the water level reaches the lower limit position, the water inlet electromagnetic valve 11 and the carbonator water supply electromagnetic valve 21 are opened and the water pump 12 is operated. When the cold water cooled by the water cooling coil 13 is supplied to the carbonator 22 and the water level reaches the upper limit position, the water inlet electromagnetic valve 11 and the carbonator water supply electromagnetic valve 21 are closed, and the operation of the water pump 12 is stopped. Then, carbon dioxide gas supplied from the carbon dioxide gas cylinder 31 is dissolved in cold water to produce carbonated water.
カーボネータ２２内で製造されて貯留されている炭酸水は、制御部により炭酸水電磁弁２４が開放されると、炭酸ガスボンベ３１から供給される炭酸ガスの圧力でカーボネータ２２から押し出され、炭酸水流量計２３、炭酸水電磁弁２４を通流し、炭酸水供給管路２０から飲料吐出ノズル１６に供給され、炭酸水流量計２３が出力するパルスが予め設定してあるパルス数に達すると、制御部が炭酸水電磁弁２４を閉塞して炭酸水の供給を停止する。 The carbonated water produced and stored in the carbonator 22 is pushed out of the carbonator 22 by the pressure of the carbon dioxide gas supplied from the carbon dioxide gas cylinder 31 when the carbonated water electromagnetic valve 24 is opened by the controller, and the flow rate of the carbonated water When the number of pulses supplied from the carbonated water supply pipe 20 to the beverage discharge nozzle 16 and output from the carbonated water flow meter 23 reaches a preset number of pulses, the control unit Closes the carbonated water solenoid valve 24 and stops the carbonated water supply.
一方、原液は、制御部により原液電磁弁３６が開放されると、炭酸ガスボンベ３１から供給される炭酸ガスの圧力で原液タンク３２から押し出され、原液冷却コイル３３、原液流量計３４、原液電磁弁３６を通流し、原液冷却コイル３３で冷やされて原液供給管路３０から飲料吐出ノズル１６に供給され、原液流量計３４が出力するパルスが予め設定してあるパルス数に達すると、制御部が原液電磁弁３６を閉塞して原液の供給を停止する。 On the other hand, when the stock solution solenoid valve 36 is opened by the control unit, the stock solution is pushed out of the stock solution tank 32 by the pressure of the carbon dioxide gas supplied from the carbon dioxide gas cylinder 31, and the stock solution cooling coil 33, the stock solution flow meter 34, the stock solution solenoid valve. When the number of pulses output from the stock solution flow meter 34 reaches a preset number of pulses, the control unit starts to flow through 36 and is cooled by the stock solution cooling coil 33 and supplied from the stock solution supply line 30 to the beverage discharge nozzle 16. The stock solution solenoid valve 36 is closed to stop the supply of the stock solution.
そして、原液タンク３２から原液冷却コイル３３、原液流量計３４、原液電磁弁３６を通流して原液供給管路３０から供給される原液と、冷水電磁弁１５または炭酸水電磁弁２４を通流して供給される希釈液としての冷水または炭酸水とが飲料吐出ノズル１６の中で混合され、調製された飲料が飲料カップ等の容器に吐出される。 Then, the stock solution supplied from the stock solution supply line 30 through the stock solution cooling coil 33, the stock solution flow meter 34, and the stock solution solenoid valve 36 from the stock solution tank 32 and the cold water solenoid valve 15 or the carbonated water solenoid valve 24 are passed. Cold water or carbonated water as a diluent to be supplied is mixed in the beverage discharge nozzle 16 and the prepared beverage is discharged into a container such as a beverage cup.
このように、飲料の原料を濃縮したシロップ等の原液を冷水や炭酸水等の希釈液で所定の比率に希釈した飲料を供給する飲料供給装置では、原液や希釈液の通過流量に同期したパルスを制御部に出力する流量計をそれぞれの供給管路に設け、制御部は、冷水電磁弁や炭酸水電磁弁を連続開放して流量計が出力するパルスが予め設定してあるパルス数に達するまで希釈液を連続吐出するとともに、原液電磁弁を間欠開放して原液流量計が出力するパルスが予め設定してあるパルス数に達するまで原液を間欠吐出し、調製した飲料を供給するようにしている。 In this way, in a beverage supply apparatus that supplies a beverage obtained by diluting a stock solution such as syrup concentrated with beverage ingredients with a diluent such as cold water or carbonated water, a pulse synchronized with the flow rate of the stock solution or diluent Is provided in each supply line, and the control unit continuously opens the chilled water solenoid valve and the carbonated water solenoid valve and the number of pulses output from the flow meter reaches a preset number of pulses. The dilute solution is continuously discharged until the stock solution solenoid valve is intermittently opened, and the stock solution is intermittently discharged until the pulse output from the stock solution flow meter reaches a preset number of pulses to supply the prepared beverage. Yes.
例えば、流量計は計測した液体１ｍｌを１パルスとして通過流量に同期した数のパルスを出力し、図８（ｂ）に示しているように、吐出１サイクルの中で、希釈液を２０ｍｌ（２０パルス）吐出する間に原液を吐出１サイクル毎に５ｍｌ（５パルス）吐出し、この間の希釈液と原液との希釈比率を「４：１」としている。そして、連続吐出させている希釈液中に原液を間欠吐出することで飲料吐出の最初から最後まで希釈液に原液が均一に混合された飲料が調製できるようにしている。 For example, the flowmeter outputs 1 pulse of the measured liquid as one pulse and outputs the number of pulses synchronized with the passing flow rate, and as shown in FIG. 5 ml (5 pulses) is discharged every discharge cycle during discharge, and the dilution ratio between the diluted solution and the stock solution is set to “4: 1”. Then, a beverage in which the stock solution is uniformly mixed with the diluent from the beginning to the end of the beverage discharge can be prepared by intermittently discharging the stock solution into the continuously discharged diluent.
この場合、原液の吐出速度は原液供給管路の内部通流抵抗で決まる。原液電磁弁を間欠開閉させることで希釈比率を所定の値に維持するためには、原液の吐出速度は希釈液の吐出速度を希釈比率で除した値よりも大きくしなくてはならない。一般的に原液は粘度が高く、また、その粘度は原液の種類によっても異なるため、原液の吐出速度調整はフローレギュレータ（流量調整器）等を用いることにより手動で調整する方法で行っていた。 In this case, the discharge speed of the stock solution is determined by the internal flow resistance of the stock solution supply line. In order to maintain the dilution ratio at a predetermined value by intermittently opening and closing the raw solenoid valve, the discharge speed of the raw liquid must be larger than the value obtained by dividing the discharge speed of the dilution liquid by the dilution ratio. In general, the stock solution has a high viscosity, and the viscosity varies depending on the type of the stock solution. Therefore, the discharge speed of the stock solution is adjusted manually by using a flow regulator (flow rate regulator) or the like.
しかしながら、原液の粘度は図７に示しているように温度によって変化し、原液温度が高くなると粘度が低くなって吐出速度が速くなる。原液温度が高くなり粘度が低く吐出速度が速いと、図８（ａ）に示しているように、原液流量計３４が出力する５パルス分の原液を吐出する時間が短くなり、原液が吐出されない時間が長くなる。また、原液温度が低くなり粘度が高く吐出速度が遅いと、図８（ｃ）に示しているように、原液流量計３４が出力する５パルス分の原液を吐出する時間が長くなる。 However, the viscosity of the stock solution varies depending on the temperature as shown in FIG. 7, and when the stock solution temperature increases, the viscosity decreases and the discharge speed increases. When the stock solution temperature becomes high, the viscosity is low, and the discharge speed is high, as shown in FIG. 8A, the time for discharging the stock solution for five pulses output from the stock solution flowmeter 34 becomes short, and the stock solution is not discharged. The time will be longer. Further, when the stock solution temperature becomes low, the viscosity is high, and the discharge speed is slow, as shown in FIG. 8C, the time for discharging the stock solution for 5 pulses output from the stock solution flowmeter 34 becomes long.
電動コンプレッサを使用する冷却装置で冷却水槽に貯留している冷却水を冷却する飲料ディスペンサやカップ式自動販売機では、冷却水槽の冷却水が設定温度まで冷える前に原液の吐出速度調整を行った場合、吐出速度調整後に冷却水槽の冷却水が設定温度に冷却されると原液の吐出速度が遅くなりすぎ、原液の吐出速度が追い付かなくなり、図８（ｃ）に示しているように、基準の吐出１サイクル中では原液５パルス分の吐出が終わらなくなり、原液が連続して吐出されるようになり、吐出されない原液が発生し、希釈比率の薄い飲料（希釈比率異常）になるという不具合が発生することとなる。 In beverage dispensers and cup-type vending machines that cool the cooling water stored in the cooling water tank using a cooling device that uses an electric compressor, the discharge rate of the concentrate was adjusted before the cooling water in the cooling water tank cooled to the set temperature. In this case, if the cooling water in the cooling water tank is cooled to the set temperature after adjusting the discharge speed, the discharge speed of the stock solution becomes too slow, and the discharge speed of the stock solution cannot catch up. As shown in FIG. During one discharge cycle, the discharge of 5 pulses of the stock solution will not end, and the stock solution will be discharged continuously, resulting in a non-discharged stock solution, resulting in a beverage with a thin dilution ratio (abnormal dilution ratio). Will be.
この原液の吐出速度を希釈液に対する希釈比率分よりもはるかに早くなるように原液供給管路の内部通流抵抗値を予め設定しておく方法も考えられる。しかしながら、原液の吐出速度が速すぎると、原液を吐出する時間が短くなり、原液が吐出されない時間が長くなると、原液が希釈液と十分に混合することができなくなるため、原液と希釈液とが十分に混ざらない状態で飲料が供給されることとなる。 A method is conceivable in which the internal flow resistance value of the stock solution supply line is set in advance so that the discharge speed of the stock solution is much faster than the dilution ratio with respect to the diluent. However, if the discharge speed of the stock solution is too fast, the time for discharging the stock solution is shortened, and if the time for which the stock solution is not ejected is long, the stock solution cannot be sufficiently mixed with the diluted solution. A drink will be supplied in the state which is not fully mixed.
このように、原液は温度によって粘度が変化することで吐出速度も大きく変化し、しかも原液の種類によっても希釈比率や粘度が大きく異なるため、原液吐出速度はその周囲温度変化の影響を大きく受けることとなる。 In this way, since the viscosity of the stock solution changes greatly with temperature, the discharge speed also changes greatly, and since the dilution ratio and viscosity vary greatly depending on the type of stock solution, the stock solution discharge speed is greatly affected by changes in the ambient temperature. It becomes.
本発明は、以上のような課題を解決するためになされたものであり、飲料供給装置を市場設置時、また、飲料の種類変更時等の原液吐出速度調整を不要とするとともに、温度変化等による原液の物性変化が起きても、常に適切な希釈比率の飲料を供給することができる飲料供給装置を提供することを目的とする。 The present invention has been made to solve the above-described problems, and does not require adjustment of the stock solution discharge speed when the beverage supply device is installed on the market or when the beverage type is changed, and the temperature change or the like. It is an object of the present invention to provide a beverage supply device that can always supply a beverage having an appropriate dilution ratio even if the physical properties of the stock solution change due to the above.

A cold water flow meter 14, a carbonated water flow meter 23, a stock solution flow meter 34 (34a, 34b, 34c, 34d) and the like are connected.
さらに、制御部９０は、水入口電磁弁１１、水ポンプ１２、冷水電磁弁１５、カーボネータ給水電磁弁２１、炭酸水電磁弁２４、原液流量調整装置３５（３５ａ、３５ｂ、３５ｃ、３５ｄ）、原液電磁弁３６（３６ａ、３６ｂ、３６ｃ、３６ｄ）などへの通電制御を行う。 Further, the control unit 90 includes a water inlet electromagnetic valve 11, a water pump 12, a cold water electromagnetic valve 15, a carbonator water supply electromagnetic valve 21, a carbonated water electromagnetic valve 24, a raw liquid flow rate adjusting device 35 (35a, 35b, 35c, 35d), a raw liquid. Energization control to the solenoid valve 36 (36a, 36b, 36c, 36d) and the like is performed.
次に、制御部９０による飲料吐出制御の手順を図４のフローチャート図を用いて説明する。先ず、飲料選択ボタン４が「ＯＮ」になると（ステップＳ１１）、飲料吐出タイムチャートを開始する（ステップＳ１２）。そして、吐出１サイクル内での希釈液（冷水または炭酸水）と原液の吐出時間をそれぞれの吐出１サイクル毎に測定し（ステップＳ１３）、希釈液吐出時間ＤＴに対する原液吐出時間ＳＴの吐出時間比率Ｒを計算する（ステップＳ１４）。 Next, the procedure of beverage discharge control by the control unit 90 will be described with reference to the flowchart of FIG. First, when the beverage selection button 4 is “ON” (step S11), a beverage discharge time chart is started (step S12). Then, the discharge time of the diluted solution (cold water or carbonated water) and the stock solution within one discharge cycle is measured for each discharge cycle (step S13), and the discharge time ratio of the stock solution discharge time ST to the diluted solution discharge time DT. R is calculated (step S14).
そして、吐出時間比率Ｒが０．８未満と確認した場合（ステップＳ１５：Ｙｅｓ）、制御部９０は、原液流量調整装置３５に信号を出力して原液吐出速度を１ステップ増やす（ステップＳ１６）。また、吐出時間比率Ｒが０．８以上と確認した場合（ステップＳ１５：Ｎｏ）、ステップＳ１７へと移動する。 When it is confirmed that the discharge time ratio R is less than 0.8 (step S15: Yes), the control unit 90 outputs a signal to the stock solution flow rate adjustment device 35 to increase the stock solution discharge speed by one step (step S16). When it is confirmed that the discharge time ratio R is 0.8 or more (step S15: No), the process moves to step S17.
さらに、吐出１サイクル内での希釈液と原液の吐出時間をそれぞれの吐出１サイクル毎に測定した結果の希釈液吐出時間ＤＴに対する原液吐出時間ＳＴの吐出時間比率Ｒが０．９を超えていると確認した場合（ステップＳ１７：Ｙｅｓ）、制御部９０は、原液流量調整装置３５に信号を出力して原液吐出速度を１ステップ減らす（ステップＳ１８）。また、吐出時間比率Ｒが０．９以下であると確認した場合（ステップＳ１７：Ｎｏ）、ステップＳ１９へと移動する。そして、飲料選択ボタン４が「ＯＦＦ」になると（ステップＳ１９：Ｙｅｓ）、飲料吐出タイムチャートを終了する（ステップＳ２０）。 Furthermore, the discharge time ratio R of the stock solution discharge time ST to the diluted solution discharge time DT as a result of measuring the discharge time of the diluted solution and the stock solution within each discharge cycle for each discharge cycle exceeds 0.9. (Step S17: Yes), the control unit 90 outputs a signal to the stock solution flow rate adjustment device 35 to reduce the stock solution discharge speed by one step (Step S18). When it is confirmed that the discharge time ratio R is 0.9 or less (step S17: No), the process moves to step S19. And if the drink selection button 4 becomes "OFF" (step S19: Yes), a drink discharge time chart will be complete | finished (step S20).
このようにして制御部９０は、吐出１サイクル内での希釈液と原液の吐出時間をそれぞれの吐出１サイクル毎に測定した結果の希釈液吐出時間ＤＴに対する原液吐出時間ＳＴの吐出時間比率Ｒが常に０．８≦Ｒ≦０．９となるように原液流量調整装置３５に信号を出力して原液吐出速度を制御することで、原液供給管路３０の原液流量調整機能が自動制御可能となり、図５に示しているように原液粘度に応じて原液吐出時間を最適化することができ、飲料供給装置１を市場設置時、また、飲料の種類変更時等の原液吐出速度調整を不要とするとともに、温度変化等による原液の物性変化が起きても、常に適切な希釈比率の飲料を供給することができる飲料供給装置１を提供することが可能となる。 In this way, the control unit 90 determines the discharge time ratio R of the stock solution discharge time ST to the diluted solution discharge time DT as a result of measuring the discharge time of the diluted solution and the stock solution in each discharge cycle for each discharge cycle. By controlling the stock solution discharge speed by outputting a signal to the stock solution flow rate adjusting device 35 so that 0.8 ≦ R ≦ 0.9, the stock solution flow rate adjusting function of the stock solution supply line 30 can be automatically controlled. As shown in FIG. 5, the stock solution discharge time can be optimized according to the stock solution viscosity, and it is not necessary to adjust the stock solution discharge speed when the beverage supply device 1 is installed on the market or when the beverage type is changed. At the same time, it is possible to provide the beverage supply apparatus 1 that can always supply a beverage having an appropriate dilution ratio even if the physical properties of the stock solution change due to a temperature change or the like.
以上説明したように本発明によれば、冷水供給管路１０から供給される冷水または炭酸水供給管路２０から供給される炭酸水と、原液供給管路３０から供給される原液と、を所定の希釈比率で混合させる制御部９０を備える飲料供給装置１において、冷水供給管路１０には、冷水の通過流量に同期した周波数のパルスを出力する冷水流量計１４と、弁を開閉して冷水の通過を許可する冷水電磁弁１５と、炭酸水供給管路２０には、炭酸水の通過流量に同期した周波数のパルスを出力する炭酸水流量計２３と、弁を開閉して炭酸水の通過を許可する炭酸水電磁弁２４と、を設け、原液供給管路３０には、原液の通過流量に同期した周波数のパルスを出力する原液流量計３４と、原液の通過流量を調製する原液流量調整装置３５と、弁を開閉して原液の通過を許可する原液電磁弁３６と、を設け、制御部９０は、冷水流量計１４または炭酸水流量計２３および原液流量計３４が出力するそれぞれの所定パルス数を吐出１サイクルとし、該吐出１サイクル毎に測定した希釈液吐出時間ＤＴに対する原液吐出時間ＳＴの吐出時間比率Ｒが予め定めている値となるように原液流量調整装置３５を制御することにより、原液供給管路３０の原液流量調整機能が自動制御可能となり、原液粘度に応じて原液吐出時間を最適化することができるので、飲料供給装置１を市場設置時、また、飲料の種類変更時等の原液吐出速度調整を不要とするとともに、温度変化等による原液の物性変化が起きても、常に適切な希釈比率の飲料を供給することができる飲料供給装置１を提供することが可能となる。 As described above, according to the present invention, the cold water supplied from the cold water supply pipe 10 or the carbonated water supplied from the carbonated water supply pipe 20 and the stock solution supplied from the stock liquid supply pipe 30 are predetermined.

Since the flow rate adjustment function can be automatically controlled and the stock solution discharge time can be optimized according to the stock solution viscosity, it is not necessary to adjust the stock solution discharge speed when the beverage supply device 1 is installed on the market or when the beverage type is changed. In addition, it is possible to provide a beverage supply apparatus 1 that can always supply a beverage having an appropriate dilution ratio even if the physical properties of the stock solution change due to a temperature change or the like.
また、制御部９０は、希釈液吐出時間ＤＴに対する原液吐出時間ＳＴの吐出時間比率Ｒを０．８〜０．９となるように原液流量調整装置３５を制御することにより、原液粘度に応じて原液吐出時間を最適化することができ、飲料供給装置１を市場設置時、また、飲料の種類変更時等の原液吐出速度調整を不要とするとともに、温度変化等による原液の物性変化が起きても、常に適切な希釈比率の飲料を供給することができる飲料供給装置１を提供することが可能となる。 Further, the control unit 90 controls the stock solution flow rate adjusting device 35 so that the discharge time ratio R of the stock solution discharge time ST with respect to the diluted solution discharge time DT is 0.8 to 0.9, thereby depending on the stock solution viscosity. The stock solution discharge time can be optimized, and it is not necessary to adjust the stock solution discharge speed when the beverage supply device 1 is installed on the market or when the beverage type is changed, and the physical properties of the stock solution change due to temperature changes, etc. However, it is possible to provide the beverage supply device 1 that can always supply a beverage having an appropriate dilution ratio.
さらに、制御部９０は、冷水電磁弁１５または炭酸水電磁弁２４を所定時間連続して開放して冷水または炭酸水を所定量連続吐出し、原液電磁弁３６を所定の回数に分割して開閉させて原液を分割して吐出することにより、冷水または炭酸水に原液が均等に混合された飲料を調製して供給することができる飲料供給装置１を提供することが可能となる。 Further, the control unit 90 opens the cold water solenoid valve 15 or the carbonated water solenoid valve 24 continuously for a predetermined time, continuously discharges a predetermined amount of cold water or carbonated water, and divides the stock solution solenoid valve 36 into a predetermined number of times to open and close. Thus, by dividing and discharging the stock solution, it is possible to provide the beverage supply device 1 that can prepare and supply a beverage in which the stock solution is evenly mixed with cold water or carbonated water.
