Description

本発明は、ビール等の炭酸飲料を供給する飲料注出供給システムに関するものである。 The present invention relates to a beverage dispensing and supplying system for supplying carbonated beverages such as beer.

従来、飲料注出供給システムにおいては、カウンター等に設置される飲料注出装置と飲料が充填された飲料容器と炭酸ガスが充填されたガスボンベからなり、
ガスボンベから送られる炭酸ガスの圧力により飲料容器内から送られた飲料を飲料注出装置に内装された冷却装置で冷却して飲料注出装置のタップから注出するものである。
Conventionally, a beverage dispensing and supplying system consists of a beverage dispensing device installed at a counter or the like, a beverage container filled with beverages, and a gas cylinder filled with carbon dioxide gas.
Beverages sent from the inside of the beverage container are cooled by the cooling device built in the beverage dispensing device by the pressure of carbon dioxide gas sent from the gas cylinder, and the beverage is dispensed from the tap of the beverage dispensing device.

ガスボンベと飲料容器はガス供給管により連結しており、飲料容器と飲料注出装置は飲料供給管により連結している。ガス供給管を介して飲料容器内に供給された炭酸ガスは、そのガス圧により飲料容器から飲料を飲料注出装置へと送り出す。 The gas cylinder and the beverage container are connected by a gas supply pipe, and the beverage container and the beverage dispensing device are connected by a beverage supply pipe. The carbon dioxide gas supplied into the beverage container through the gas supply pipe sends the beverage from the beverage container to the beverage dispenser by the gas pressure.

この飲料注出装置から飲料をグラスに注出している際に、飲料容器内の飲料が切れると炭酸ガスのみが飲料注出装置のタップから噴出してしまうという問題があった。また、飲料容器に圧入する炭酸ガスの圧力値も飲料の温度に見合った適正な圧力値が必要であり、不適正な圧力で供給されると飲料の泡が異常に過多となり、又は逆に気抜けした飲料となってしまい品質を損なうという問題があった。 When the beverage is being poured into the glass from this beverage dispensing device, there is a problem that only carbon dioxide gas is ejected from the tap of the beverage dispensing device when the beverage in the beverage container runs out. In addition, the pressure value of the carbon dioxide gas that is press-fitted into the beverage container also needs to be an appropriate pressure value that matches the temperature of the beverage, and if it is supplied at an inappropriate pressure, the bubbles in the beverage will become abnormally excessive, or conversely, the air will escape. There was a problem that the quality of the beverage was impaired.

これらの問題を解決するため、特許文献1には、飲料の種類及び温度に係わらず、飲料容器の飲料の液切れを正確かつ適切なタイミングに行えるようにする飲料供給装置が開示されている。
また、引用文献2には、ビール樽に圧入する加圧ガスの圧力値を自動的に適正値に調整可能なビール樽の圧力調整装置と、ビールの有無を検知する液体センサとビール樽と冷却注出装置との接続を絶つ遮断弁とによるビールの吹きこぼれ防止手段が開示されている。
In order to solve these problems, Patent Document 1 discloses a beverage supply device that enables the beverage in the beverage container to be drained at an accurate and appropriate timing regardless of the type and temperature of the beverage.
Further, Reference 2 describes a beer barrel pressure adjusting device that can automatically adjust the pressure value of the pressurized gas pressed into the beer barrel to an appropriate value, a liquid sensor that detects the presence or absence of beer, a beer barrel, and cooling. A means for preventing beer spillage by using a shutoff valve that disconnects from the dispensing device is disclosed.

特許文献1に記載の飲料供給装置には、飲料供給管に1対の電極を有した液切れセンサと飲料の温度を検出する温度センサを別個に設けて、検出される電位差を検出温度に基づいて変更する検知手段により飲料の液切れを正確かつ適切なタイミングで行えるようにしている。
特許文献2に記載のビール樽圧力調整装置では、ビール管に設けた温度センサにより測定されたビールの測定値に基づいてビールに供給するガス圧の適正値を算出して調圧後の加圧ガスをビール樽に圧入している。
また、吹きこぼれ防止手段では、ビール管に圧力調整用の温度センサを挟んでその上流側に遮断弁、下流側に液体センサを配置して液体センサがビールを検知しなかったときに遮断弁を閉弁して加圧ガスだけが飲料注出装置に送出されることを阻止してビールの吹きこぼれを防止している。
The beverage supply device described in Patent Document 1 is provided with a liquid drainage sensor having a pair of electrodes in the beverage supply pipe and a temperature sensor for detecting the temperature of the beverage separately, and the detected potential difference is based on the detected temperature. The detection means that changes the temperature makes it possible to drain the beverage at an accurate and appropriate timing.
In the beer barrel pressure adjusting device described in Patent Document 2, the appropriate value of the gas pressure supplied to beer is calculated based on the measured value of beer measured by the temperature sensor provided in the beer pipe, and the pressure after adjusting the pressure is adjusted. Gas is pressed into a beer barrel.
In the spill prevention means, a temperature sensor for pressure adjustment is sandwiched between beer pipes, a shutoff valve is placed on the upstream side, and a liquid sensor is placed on the downstream side, and the shutoff valve is closed when the liquid sensor does not detect beer. By valve, only the pressurized gas is prevented from being sent to the beverage dispenser to prevent the beer from spilling.

飲料供給装置に連結する飲料容器やガスボンベの設置場所は、一般に非常に狭い場所に限定されており、また飲料容器と飲料供給装置を連結する配管等は、飲料容器を交換することを考慮して一定の距離を確保しておくのが望ましいものとなっている。
従って、それに付帯させる液切れ検知やガス圧の調整圧入の装置もできる限り小型化して既存の飲料供給装置に簡便に取付けられるようにコンパクトな形態が要求される。また、温度センサの測定値を基準にして液切れの検知や、ガス圧の調整圧入が行われるため、雰囲気温度に影響を受けていない飲料容器内の液温に近い飲料の温度を正確に測定するのが好ましい。
The installation location of the beverage container and gas cylinder connected to the beverage supply device is generally limited to a very narrow space, and the piping connecting the beverage container and the beverage supply device is considered to replace the beverage container. It is desirable to secure a certain distance.
Therefore, the device for detecting liquid shortage and adjusting the gas pressure to be attached to the device is also required to be as small as possible and compact so that it can be easily attached to the existing beverage supply device. In addition, since liquid shortage is detected and gas pressure is adjusted and press-fitted based on the measured value of the temperature sensor, the temperature of the beverage that is close to the liquid temperature in the beverage container that is not affected by the ambient temperature is accurately measured. It is preferable to do so.

しかしながら、特許文献1及び2の飲料供給装置と圧力調整装置では温度センサを他の液切れセンサ等とは別個に独立して飲料供給管に装着しており、小型化や簡便性の点においてコンパクトな形態に欠ける問題があった。
また、温度センサの装着位置についても、特許文献1及び2共に飲料容器から離れた飲料供給装置に近い箇所の飲料供給管に装着されている。このことから雰囲気温度に影響を受けた飲料の温度を測定することになり、飲料容器内の液温に近い飲料の温度を測定することができなかった。
また、温度センサの測定値を基準にして液切れ検知とガス圧の調整圧入の両方を行うものではないため効率性に欠けるという問題があった。
However, in the beverage supply device and the pressure adjusting device of Patent Documents 1 and 2, the temperature sensor is mounted on the beverage supply pipe independently of other liquid drainage sensors and the like, and is compact in terms of miniaturization and convenience. There was a problem that it lacked a proper form.
Further, regarding the mounting position of the temperature sensor, both Patent Documents 1 and 2 are mounted on the beverage supply pipe at a position close to the beverage supply device away from the beverage container. From this, the temperature of the beverage affected by the atmospheric temperature was measured, and the temperature of the beverage close to the liquid temperature in the beverage container could not be measured.
Further, there is a problem that the efficiency is lacking because both the liquid shortage detection and the gas pressure adjustment press-fitting are not performed based on the measured value of the temperature sensor.

本発明は、係る問題を解決するために、液体センサと温度センサを併設してコンパクトな形態とし、既存の飲料注出供給システムにも容易に取り付けられ、また飲料容器に近い箇所に装着することが可能であり、更には1つの温度センサによる測定値を基準にして液切れ検知とガス圧の調整圧入の両方を正確且つ効率的に行なえるようにすることを目的とする。
さらに本発明は、各店舗に設置された飲料注出装置から注がれる飲料の品質の同一性を維持して提供できるように装置が正常に運転されているか液体センサ、温度センサ等のデータ及びそれらに付随する遮断弁等の開閉状態を一括して管理する体制を整え、問題が発生した場合には即時対応できることを目的とする。
In order to solve the problem, the present invention has a compact form in which a liquid sensor and a temperature sensor are installed side by side, can be easily attached to an existing beverage dispensing and supplying system, and can be installed near a beverage container. Furthermore, the purpose is to enable accurate and efficient both liquid shortage detection and gas pressure adjustment press-fitting based on the value measured by one temperature sensor.
Further, according to the present invention, whether the device is operating normally so that the quality of the beverages poured from the beverage dispensing devices installed in each store can be maintained and provided, and the data of the liquid sensor, temperature sensor, etc. The purpose is to establish a system to collectively manage the open / closed state of the shutoff valves, etc. that accompany them, and to be able to respond immediately if a problem occurs.

以下、本発明の最適と思われる実施の形態について、図1〜5を参照しながら説明する。 Hereinafter, the most suitable embodiment of the present invention will be described with reference to FIGS. 1 to 5.

図1は、本発明の第一の実施形態として、飲料注出供給システムの飲料容器02と飲料注出装置01との間において、液切れ検知自動閉弁手段を示したものである。液切れ検知自動閉弁手段は、飲料の温度を測定する温度センサ11と、飲料の電気抵抗値を測定する液体センサ20と、飲料容器02と飲料注出装置01を連結する飲料供給管06を遮断する遮断弁12と、液切れ検知のプログラムが組み込まれたマイクロコンピュータを内蔵した液切れ制御装置10から構成される。 FIG. 1 shows, as the first embodiment of the present invention, a liquid shortage detection automatic valve closing means between the beverage container 02 and the beverage dispensing device 01 of the beverage dispensing and supplying system. The liquid shortage detection automatic valve closing means includes a temperature sensor 11 for measuring the temperature of the beverage, a liquid sensor 20 for measuring the electric resistance value of the beverage, and a beverage supply pipe 06 connecting the beverage container 02 and the beverage dispensing device 01. It is composed of a shutoff valve 12 for shutting off and a runout control device 10 having a built-in microcomputer in which a runout detection program is incorporated.

具体的には、飲料容器02にガスボンベ03からのガス供給管05を連結し、前記飲料容器02から飲料供給管06を飲料注出装置01に連結して飲料を送出する飲料注出供給システムに、飲料容器02に取り付けたデイスペンスヘッド07の飲料注出口09に温度センサ11を液体センサ20に併設して装着し、前記飲料容器02と飲料注出装置01を連結する飲料供給管06に遮断弁12を装着している。これらの温度センサ11、液体センサ20、及び遮断弁12は、液切れ制御装置10と接続している。
尚、ガスボンベ03に充填するガスの種類として、炭酸ガス、窒素ガスがあり、提供する飲料により使い分けることが可能である。ここでは炭酸ガスの使用を例にして説明する。
Specifically, in a beverage dispensing and supplying system in which a gas supply pipe 05 from a gas cylinder 03 is connected to a beverage container 02, and a beverage supply pipe 06 is connected to a beverage dispensing device 01 from the beverage container 02 to deliver a beverage. , A temperature sensor 11 is attached to the beverage inlet 09 of the beverage head 07 attached to the beverage container 02 alongside the liquid sensor 20, and is cut off from the beverage supply pipe 06 connecting the beverage container 02 and the beverage dispenser 01. A valve 12 is attached. The temperature sensor 11, the liquid sensor 20, and the shutoff valve 12 are connected to the liquid out control device 10.
The type of gas to be filled in the gas cylinder 03 includes carbon dioxide gas and nitrogen gas, which can be used properly depending on the beverage to be provided. Here, the use of carbon dioxide gas will be described as an example.

デイスペンスヘッド07の飲料注出口09から注出された飲料は、液体センサ20に併設された温度センサ11によりその温度が測定され液切れ制御装置10に入力される。また、液体センサ20は、飲料の有・無により変化する電気抵抗値を測定するための1対の電極を備え、飲料注出口09から注出された飲料は、その1対の電極間を通過することで電気抵抗値が測定され液切れ制御装置10に入力される。 The temperature of the beverage poured out from the beverage inlet 09 of the device head 07 is measured by the temperature sensor 11 provided in the liquid sensor 20 and input to the liquid drainage control device 10. Further, the liquid sensor 20 is provided with a pair of electrodes for measuring the electric resistance value that changes depending on the presence or absence of the beverage, and the beverage dispensed from the beverage injection port 09 passes between the pair of electrodes. By doing so, the electric resistance value is measured and input to the liquid drainage control device 10.

液切れ制御装置10は、メモリに液切れ検知プログラムを有しており、内蔵するマイクロコンピュータにより液切れ検知プログラムを実行している。 The liquid-out control device 10 has a liquid-out detection program in the memory, and executes the liquid-out detection program by a built-in microcomputer.

液体センサ20の1対の電極により測定される電気抵抗値は、通過する飲料の温度によって変化する。すなわち、飲料の温度が高くなると飲料に含まれるイオンが活発化して電気抵抗が小さくなる。従って、液体センサ20の1対の電極間を通過する飲料の温度が高くなるほど電気抵抗値は小さくなる。 The electrical resistance value measured by the pair of electrodes of the liquid sensor 20 varies depending on the temperature of the beverage passing through. That is, when the temperature of the beverage rises, the ions contained in the beverage become active and the electrical resistance decreases. Therefore, the higher the temperature of the beverage passing between the pair of electrodes of the liquid sensor 20, the smaller the electric resistance value.

本発明者らは、液切れ検知プログラムのデータ収集の目的で、対象とする種類別炭酸入り飲料の電気抵抗値の試験測定を複数回行い、飲料の種類、飲料温度の違いによる、正常な流れの時と液切れ時、の電気抵抗値の変動を測定した。 For the purpose of collecting data of the liquid shortage detection program, the present inventors performed multiple test measurements of the electric resistance value of the target type-specific carbonated beverage, and the normal flow due to the difference in the beverage type and the beverage temperature. The fluctuation of the electric resistance value was measured at the time of and when the liquid was drained.

本発明の液切れ制御装置10は、上記したように予め飲料の種類及び飲料温度の違による電気抵抗値を測定し、その測定値に基づき液切れ検知プログラムの液切れの基準値を設定している。稼働中に液体センサ20の1対の電極間を流れる飲料の電気抵抗値と温度センサ11による液温値が液切れ制御装置10に入力されると、液切れ検知プログラムに設定されている温度帯の液切れの基準値と照合される。そして、液切れの基準値を越えると液切れであると検知する。 As described above, the liquid-out control device 10 of the present invention measures the electric resistance value due to the difference in the type of beverage and the beverage temperature in advance, and sets the reference value of liquid-out of the liquid-out detection program based on the measured value. There is. When the electric resistance value of the beverage flowing between the pair of electrodes of the liquid sensor 20 and the liquid temperature value by the temperature sensor 11 are input to the liquid shortage control device 10 during operation, the temperature range set in the liquid shortage detection program is set. It is collated with the standard value of liquid drainage. Then, when the reference value for running out of liquid is exceeded, it is detected that the liquid has run out.

具体的には、液切れ検知プログラムでは、飲料温度を0〜19℃と、20〜26℃と、27〜35℃の3区分の温度帯のテーブルに分け、飲料別の液切れとする電気抵抗値の基準値を設定している。例えば、ビール飲料の場合、液切れの基準値を、0〜19℃の温度帯では10Ωに、20〜26℃の温度帯では8Ω、27〜35℃の温度帯では6Ωに設定している。尚、ここでは、温度帯のテーブルを3区分にしているが、この区分数に限定されるものでない。 Specifically, in the liquid shortage detection program, the beverage temperature is divided into tables in three temperature zones of 0 to 19 ° C., 20 to 26 ° C., and 27 to 35 ° C. The standard value of the value is set. For example, in the case of beer beverages, the reference value for running out of liquid is set to 10 Ω in the temperature range of 0 to 19 ° C., 8 Ω in the temperature range of 20 to 26 ° C., and 6 Ω in the temperature range of 27 to 35 ° C. Although the temperature zone table is divided into three categories here, the number of categories is not limited to this.

また、本発明の場合には、液体センサ20と温度センサ11を飲料注出口09に装着していることから、飲料容器内と液体センサ通過時の飲料の温度変化はほとんど認められず、また、飲料容器内の飲料温度も測定調査によると7時間での経時変化は約2℃であり、飲料温度の変化が非常に低い水準に留まっている。従って、飲料容器内の飲料温度を基に温度範囲を狭く特定できることから液切れ検知プログラムの温度帯のテーブルを1区分にすることも可能である。 Further, in the case of the present invention, since the liquid sensor 20 and the temperature sensor 11 are attached to the beverage inlet 09, almost no temperature change in the beverage container and when passing through the liquid sensor is observed, and the temperature of the beverage is hardly changed. According to the measurement survey, the change in the beverage temperature in the beverage container with time was about 2 ° C. in 7 hours, and the change in the beverage temperature remained at a very low level. Therefore, since the temperature range can be narrowly specified based on the beverage temperature in the beverage container, it is possible to divide the table of the temperature zone of the liquid shortage detection program into one category.

液体センサ20は、パルス制御を用いて飲料の電気抵抗値を測定している。本発明では、1秒間に4回のパルス間隔で飲料の電気抵抗値を測定しており、液切れ検知プログラムは、液体センサ20がそのパルスにより4回連続して液切れの基準値を超えた電気抵抗値を測定すると液切れであると検知するように設定している。
尚、上記パルス間隔の数値と連続して液切れの基準値を超える数値は、1例であり必要に応じて適宜変更することができる。
また、この際に印加する電圧は、水の電気分解電圧と公知されている1.23Vより以下の電圧に設定して印加しており、パルス制御と併せて飲料品質などへの影響を極力少なくなるように設定している。
The liquid sensor 20 measures the electric resistance value of the beverage using pulse control. In the present invention, the electric resistance value of the beverage is measured at pulse intervals of 4 times per second, and the liquid sensor 20 exceeds the reference value of liquid drainage 4 times in succession by the pulse in the liquid shortage detection program. It is set to detect that the liquid has run out when the electrical resistance value is measured.
It should be noted that the numerical value of the pulse interval and the numerical value exceeding the reference value of liquid drainage in succession is an example and can be appropriately changed as needed.
Further, the voltage applied at this time is set to a voltage lower than 1.23 V, which is known as the electrolysis voltage of water, and is applied in combination with pulse control to minimize the influence on beverage quality and the like. It is set to be.

液体センサ20がこれらの予めプログラムに入力されている温度帯の液切れの基準値を超えた電気抵抗値を4回連続して測定すると、液切れ検知プログラムは、液切れであると検知する。 When the liquid sensor 20 continuously measures the electric resistance value exceeding the reference value of the liquid drainage in the temperature range input to the program in advance four times, the liquid shortage detection program detects that the liquid has run out.

尚、4回連続を液切れの検知条件としたのは、正常な飲料の流れであっても多少の泡が含まれていると、液体センサ20が液切れの基準値を超えた電気抵抗値を測定する場合があり、それによる誤作動を防止するためである。 It should be noted that the condition for detecting the liquid out of the liquid four times in a row is that the liquid sensor 20 exceeds the reference value of the liquid out when the liquid sensor 20 contains some bubbles even in a normal beverage flow. This is to prevent malfunction due to the measurement.

液切れ制御装置10は、上述した液切れ検知プログラムによって液切を検知したときは、飲料供給管06に装着している遮断弁12に弁を閉じる信号を送り遮断弁12を閉弁する。これにより、飲料容器02と飲料注出装置01を繋ぐ飲料供給管06は遮断され、炭酸ガスが飲料注出装置01のタップから噴出するのを防止できる。 When the liquid outage control device 10 detects the liquid outage by the above-mentioned liquid outage detection program, the liquid outage control device 10 sends a signal to close the valve to the shutoff valve 12 mounted on the beverage supply pipe 06 to close the shutoff valve 12. As a result, the beverage supply pipe 06 connecting the beverage container 02 and the beverage dispensing device 01 is cut off, and carbon dioxide gas can be prevented from being ejected from the tap of the beverage dispensing device 01.

飲料容器02と飲料注出装置01は、一定の距離を置いて位置しているため、飲料容器02と飲料注出装置01を連結する飲料供給管06はある程度の長さが要求される。従って、飲料供給管06に滞留している飲料は、雰囲気温度に影響を受け易く、特に夏場は、液温が上昇して飲料容器内の飲料との温度差が広がる。
このことで、飲料注出装置01で飲料の注出が開始されると飲料供給管06を通過する飲料の温度は一時的に急激に変化することになり、飲料供給管06に液体センサ20を設置しているとその飲料温度の急激な変化により安定した電気抵抗値の測定ができない。
Since the beverage container 02 and the beverage dispensing device 01 are located at a certain distance, the beverage supply pipe 06 connecting the beverage container 02 and the beverage dispensing device 01 is required to have a certain length. Therefore, the beverage staying in the beverage supply pipe 06 is easily affected by the atmospheric temperature, and the liquid temperature rises particularly in the summer, and the temperature difference from the beverage in the beverage container widens.
As a result, when the beverage dispensing device 01 starts pouring the beverage, the temperature of the beverage passing through the beverage supply pipe 06 temporarily suddenly changes, and the liquid sensor 20 is attached to the beverage supply pipe 06. If it is installed, stable electric resistance value cannot be measured due to a sudden change in the beverage temperature.

本発明では特に、液体センサ20とそれに併設した温度センサ11が、飲料容器02に取り付けたデイスペンスヘッド07の飲料注出口09に装着されていることから飲料容器内の飲料の温度に極力近い温度帯での電気抵抗値を測定できる。このため、飲料注出供給システムが置かれている雰囲気温度に影響を受けていない温度帯で測定された飲料の安定した電気抵抗値により液切れか否かの検知を行うことができる。 In particular, in the present invention, since the liquid sensor 20 and the temperature sensor 11 attached thereto are attached to the beverage spout 09 of the beverage head 07 attached to the beverage container 02, the temperature is as close as possible to the temperature of the beverage in the beverage container. The electrical resistance value in the band can be measured. Therefore, it is possible to detect whether or not the beverage has run out based on the stable electrical resistance value of the beverage measured in a temperature range that is not affected by the ambient temperature in which the beverage injection and supply system is placed.

また、液切れ制御装置10は、提供する飲料が異なっても使用することができる。例えば飲料の種類として、ビール、炭酸割りウイスキー、炭酸割り焼酎、黒ビール、炭酸入りソフトドリンク等が挙げられる。これらの飲料は、それぞれに含まれるイオンの量が異なり、電気抵抗値及び液切れの基準値も飲料の種類ごとに異なる。従って、飲料の種類別に電気抵抗値及び液切れの基準値のデータを液切れ検知プログラムに設定しておくことで提供する炭酸飲料の飲料切れを検知できる。 Further, the liquid shortage control device 10 can be used even if the provided beverages are different. For example, the types of beverages include beer, carbonated whiskey, carbonated shochu, black beer, and carbonated soft drinks. The amount of ions contained in each of these beverages is different, and the electric resistance value and the reference value for running out of liquid are also different for each type of beverage. Therefore, by setting the data of the electric resistance value and the reference value of the liquid outage for each type of beverage in the liquid outage detection program, it is possible to detect the out of drink of the carbonated beverage provided.

図2は、本発明の第二の実施形態として、図1に示した飲料容器02と飲料注出装置01との間に液切れ検知自動閉弁手段を設けた飲料注出供給システムに、さらにガスボンベ03と飲料容器02とを連結するガス供給管05にガス調圧供給手段を設けた飲料注出供給システムを示したものである。尚、上記ガス調圧供給手段に使用する装置は市販のものを使用している。 FIG. 2 shows, as a second embodiment of the present invention, a beverage dispensing and supplying system provided with an automatic valve closing means for detecting liquid shortage between the beverage container 02 and the beverage dispensing device 01 shown in FIG. It shows a beverage dispensing and supplying system in which a gas pressure adjusting and supplying means is provided in a gas supply pipe 05 connecting a gas cylinder 03 and a beverage container 02. The device used for the gas pressure regulating supply means is a commercially available device.

このガス調圧供給手段は、炭酸ガスの圧入を調整する調圧弁31と飲料容器02に圧入される炭酸ガスの圧を測定する圧力センサ32、そして飲料の液温により圧入する適正なガス圧のプログラムが組み込まれたマイクロコンピュータを内蔵したガス圧制御装置30から構成されている。 The gas pressure adjusting supply means includes a pressure regulating valve 31 for adjusting the press-fitting of carbon dioxide gas, a pressure sensor 32 for measuring the pressure of carbon dioxide gas press-fitted into the beverage container 02, and an appropriate gas pressure to be press-fitted according to the liquid temperature of the beverage. It is composed of a gas pressure control device 30 having a built-in microcomputer in which a program is incorporated.

具体的には、このガス調圧供給手段を構成する装置は、ガスボンベ03と飲料容器02を連結するガス供給管05に装着されており、ガスボンベ03から減圧弁04によって減圧された加圧ガスは、ガス供給管05に装着された調圧弁31と圧力センサ32を介して飲料容器02に送られる。 Specifically, the device constituting the gas pressure adjusting supply means is attached to the gas supply pipe 05 connecting the gas cylinder 03 and the beverage container 02, and the pressurized gas decompressed from the gas cylinder 03 by the pressure reducing valve 04 is released. , Is sent to the beverage container 02 via the pressure regulating valve 31 attached to the gas supply pipe 05 and the pressure sensor 32.

この調圧弁31と圧力センサ32は、ガス圧制御装置30に接続しており、ガス圧制御装置30から発信される信号により調圧弁31の開閉により飲料容器02に送る炭酸ガスの圧力を調整している。 The pressure regulating valve 31 and the pressure sensor 32 are connected to the gas pressure control device 30, and the pressure of carbon dioxide gas sent to the beverage container 02 is adjusted by opening and closing the pressure regulating valve 31 by a signal transmitted from the gas pressure control device 30. ing.

ガス圧制御装置30は、液切れ制御装置10と接続しており、飲料容器02のデイスペンスヘッド07の飲料注出口09に装着した液体センサ20に併設された温度センサ11の飲料温度の測定値を信号により受け取り、その測定値から飲料容器02に供給するガス圧の適正な計測値を算出し、これと圧力センサ32の測定値とを比較して、圧力センサの測定値が適正な計測値と一致するように信号を調圧弁31に出力する。 The gas pressure control device 30 is connected to the liquid drainage control device 10, and is a measured value of the beverage temperature of the temperature sensor 11 attached to the liquid sensor 20 attached to the beverage inlet 09 of the device head 07 of the beverage container 02. Is received by a signal, an appropriate measured value of the gas pressure supplied to the beverage container 02 is calculated from the measured value, and this is compared with the measured value of the pressure sensor 32, and the measured value of the pressure sensor is an appropriate measured value. A signal is output to the pressure regulating valve 31 so as to match.

当該信号を受けた調圧弁31は、その信号に応じて弁の開・閉によりガス圧を昇圧又は降圧して飲料容器02に供給するガス圧を調整する。この時の温度センサ11により測定された飲料の温度は、飲料容器内の液温にほぼ等しいため適正な圧力で炭酸ガスを飲料容器02に供給することができる。 The pressure regulating valve 31 that receives the signal adjusts the gas pressure supplied to the beverage container 02 by increasing or decreasing the gas pressure by opening / closing the valve according to the signal. Since the temperature of the beverage measured by the temperature sensor 11 at this time is substantially equal to the temperature of the liquid in the beverage container, carbon dioxide gas can be supplied to the beverage container 02 at an appropriate pressure.

尚、飲料の温度による飲料に圧入する適正な炭酸ガス量は公知であり、また調圧弁31の開閉によって圧力を上げたり、下げたりする技術も公知であるので、その技術を利用することができる。 The appropriate amount of carbon dioxide gas to be press-fitted into the beverage according to the temperature of the beverage is known, and the technique of increasing or decreasing the pressure by opening and closing the pressure regulating valve 31 is also known, so that technique can be used. ..

このようにガス調圧供給手段では、液切れ検知自動閉弁手段の温度センサ11で測定したデータを併用して使用しているので、別個にガス調圧供給手段用の温度センサを設ける必要がない。 In this way, since the gas pressure regulating supply means also uses the data measured by the temperature sensor 11 of the liquid shortage detection automatic valve closing means, it is necessary to separately provide a temperature sensor for the gas pressure regulating supply means. Absent.

図3は、本発明の第三実施形態に係る残留飲料注出手段を示したものである。この残留飲料注出手段は、ガス供給管05の下流側を分岐して、炭酸ガスが飲料容器02を介さずに飲料供給管06に流れるように液切れ検知自動閉弁手段の液体センサの上流側に接続した分岐管40と、当該分岐管40に装着したガス供給弁41により構成される。 FIG. 3 shows the residual beverage pouring means according to the third embodiment of the present invention. The residual beverage pouring means branches off the downstream side of the gas supply pipe 05, and upstream of the liquid sensor of the liquid shortage detection automatic valve closing means so that carbon dioxide gas flows to the beverage supply pipe 06 without passing through the beverage container 02. It is composed of a branch pipe 40 connected to the side and a gas supply valve 41 attached to the branch pipe 40.

このガス供給弁41と分岐管40で構成される残留飲料注出手段は、飲料注出供給システムが稼動中の間は、ガス供給弁41は常時閉弁している。そして、営業終了時にガス供給弁41を開弁することで、飲料容器02と飲料注出装置01を連結する飲料供給管06及び飲料注出装置内に残留する飲料を炭酸ガスにより注出することを目的とする。 In the residual beverage dispensing means composed of the gas supply valve 41 and the branch pipe 40, the gas supply valve 41 is always closed while the beverage dispensing and supplying system is in operation. Then, by opening the gas supply valve 41 at the end of business, the beverage remaining in the beverage supply pipe 06 connecting the beverage container 02 and the beverage dispensing device 01 and the beverage dispensing device is discharged by carbon dioxide gas. With the goal.

具体的には、飲料容器02のデイスペンスヘッド07のヘッドレバー08を引き上げると飲料容器02の口部が閉じられる。これによりガスボンベ03からのガス供給管05を介した飲料容器02への炭酸ガスの供給と飲料容器02からの飲料供給管06を介した飲料注出装置01への飲料の供給が遮断される。 Specifically, when the head lever 08 of the device head 07 of the beverage container 02 is pulled up, the mouth portion of the beverage container 02 is closed. As a result, the supply of carbon dioxide gas from the gas cylinder 03 to the beverage container 02 via the gas supply pipe 05 and the supply of the beverage from the beverage container 02 to the beverage dispensing device 01 via the beverage supply pipe 06 are cut off.

この時、液切れ検知自動閉弁手段の飲料供給管06に装着された遮断弁12は開弁した状態になっている。また、ガス供給管05にガス調圧供給手段を設けている場合には、ガス調圧供給手段の調圧弁31も液切れ検知自動閉弁手段の遮断弁12と同様に開弁した状態になっている。従って、残留飲料注出手段のガス供給弁41を開くとガスボンベ03からの炭酸ガスは、ガス供給管05から分岐管40を経由して飲料容器02を介さずに飲料供給管06へと流れ飲料注出装置01に供給される。 At this time, the shutoff valve 12 attached to the beverage supply pipe 06 of the liquid shortage detection automatic valve closing means is in the opened state. Further, when the gas supply pipe 05 is provided with the gas pressure regulating supply means, the pressure regulating valve 31 of the gas pressure regulating supply means is also in a state of being opened in the same manner as the shutoff valve 12 of the liquid shortage detection automatic valve closing means. ing. Therefore, when the gas supply valve 41 of the residual beverage dispensing means is opened, the carbon dioxide gas from the gas cylinder 03 flows from the gas supply pipe 05 to the beverage supply pipe 06 via the branch pipe 40 without passing through the beverage container 02. It is supplied to the dispensing device 01.

液切れ制御装置10からガス供給弁41に弁の開閉の信号を送ることができる。信号を送るとガス供給弁41は、所定の時間開弁して装置内に残留した飲料を炭酸ガスにより押し出すことができる。
そして、所定の時間が経過するとガス供給弁41は自動的に閉弁して炭酸ガスの供給は停止する。
A signal for opening and closing the valve can be sent from the liquid out control device 10 to the gas supply valve 41. When a signal is sent, the gas supply valve 41 can be opened for a predetermined time to push out the beverage remaining in the apparatus by carbon dioxide gas.
Then, when a predetermined time elapses, the gas supply valve 41 is automatically closed and the supply of carbon dioxide gas is stopped.

これにより、飲料供給管06と飲料注出装置01に残留する飲料を、吹きこぼすことなく、完全に注出することができる。したがって、この構成によれば、営業終了時に飲料容器02に残存している飲料に影響を与えることなく、飲料供給管06と飲料注出装置01に残留する飲料を有効に消費することができる。 As a result, the beverage remaining in the beverage supply pipe 06 and the beverage dispensing device 01 can be completely dispensed without spilling. Therefore, according to this configuration, the beverage remaining in the beverage supply pipe 06 and the beverage dispensing device 01 can be effectively consumed without affecting the beverage remaining in the beverage container 02 at the end of business.

It is composed of an annular electrode 22. As the member of the insulator, there are an inorganic material such as ceramic and glass, and a resin material such as polyethylene, evoxy resin and phenol resin, but a resin material is preferable from the viewpoint of processing and cost. Further, as described above, the present invention is characterized in that the temperature sensor 11 is provided side by side with the liquid sensor 20 to integrate the liquid sensor 20 and the temperature sensor 11.

一対の電極22は、導管23の内周壁24に嵌めこまれており、第一の電極22aは導管23の飲料の入口側である下方部に、第二の電極22bは飲料の出口側である上方部に位置している。 The pair of electrodes 22 are fitted into the inner peripheral wall 24 of the conduit 23, the first electrode 22a is on the lower portion of the conduit 23 on the beverage inlet side, and the second electrode 22b is on the beverage outlet side. It is located in the upper part.

第一の電極22aには、温度センサ11を併設してあり、これらの一対の電極22と温度センサ11は液切れ制御装置10に接続している。尚、温度センサ11の併設は第一の電極22aに限定されるものでなく、第一又は第二の電極22bのいずれか一方に併設されていればよい。 A temperature sensor 11 is provided next to the first electrode 22a, and the pair of electrodes 22 and the temperature sensor 11 are connected to the liquid out control device 10. The temperature sensor 11 is not limited to the first electrode 22a, and may be installed on either the first or second electrode 22b.

本体部21の飲料の入口部25はデイスペンスヘッド07の飲料注出口09に接続し、本体部21の飲料の出口部26は飲料注出装置01に連結する飲料供給管06に接続している。 The beverage inlet 25 of the main body 21 is connected to the beverage inlet 09 of the device head 07, and the beverage outlet 26 of the main body 21 is connected to the beverage supply pipe 06 connected to the beverage dispenser 01. ..

デイスペンスヘッド07のヘッドレバー08が引き下げられた状態で飲料容器02から飲料が飲料注出装置01に供給されると、飲料は液体センサ20の本体部21の導管内を下方から上方へ流れていく。この時に飲料の電気抵抗値と温度とが常時測定され、それらのデータが液切れ制御装置10に送られる。 When the beverage is supplied from the beverage container 02 to the beverage dispensing device 01 with the head lever 08 of the device head 07 pulled down, the beverage flows from the bottom to the top in the conduit of the main body 21 of the liquid sensor 20. I will go. At this time, the electric resistance value and the temperature of the beverage are constantly measured, and the data are sent to the liquid drainage control device 10.

飲料容器02が空となり新たな飲料容器02と交換する場合には、空の容器からデイスペンスヘッド07を取り外し、新たな飲料容器02に取付けるだけの簡単な作業により液切れ検知を継続して行うことができる。 When the beverage container 02 becomes empty and is replaced with a new beverage container 02, the drainage detection is continuously performed by simply removing the device head 07 from the empty container and attaching it to the new beverage container 02. be able to.

Then, these data can be confirmed at any time by the access code for each store by the user personal computer or the OS for the mobile device via the communication network 55. In addition, when a plurality of devices are arranged in the store, it can be confirmed by the individual access code of each device.

また、例えば遮断弁12に弁を開く信号を送っても開弁しない異常事態が液切れ制御装置10に発生した場合は、液切れ制御装置10がそれを検知し、通信装置58,通信ネットワーク55を介して、管理コンピュータ51へ異常発生信号を通知する。管理コンピュータ51では、異常発生店舗、異常発生個所,異常内容,必要な処置等を関係者に通知する。ここで関係者とは、該当する店舗の責任者や営業担当責任者等のユーザ、及び保全サービス会社59や保全サービス会社59から携帯機器用OS等を介して同様な通知が即時配信される当該店舗の装置の保全・修繕を受持つ保全担当者をいう。 Further, for example, when an abnormal situation occurs in the liquid out control device 10 in which the valve does not open even if a signal for opening the valve is sent to the shutoff valve 12, the liquid out control device 10 detects it, and the communication device 58 and the communication network 55 The management computer 51 is notified of the abnormality occurrence signal via the above.
