Definitions
- the invention relates to an automatic beverage dispenser, in particular an automatic cocoa dispenser, in which two liquids of different viscosities are mixed together in a predetermined quantity ratio and which dispenses a predetermined amount of the beverage mixed from these liquids.
- Some beverages such as cocoa in particular, only have a special pleasant taste when they are drunk freshly prepared.
- Vending machine for dispensing drinks which are to deliver such drinks freshly prepared and which are intended for use in canteens, self-service restaurants or the like, for example, must therefore be able to dispense the basic liquid, for example hot water, and the beverage material to be added to it, for example an extract or cocoa paste to mix with each other in a predetermined ratio and to deliver in precisely measured total quantity.
- Simple flow control valves are not very suitable for the quantity adjustment of the beverage components, since the flow rate of the beverage components depends very much on the viscosity of the same.
- Piston pumps of this type also require a considerable amount of maintenance and tend to fail, particularly if there are longer downtimes between individual beverage removal processes, in which beverage constituents can settle on pump parts and possibly solidify.
- a device for the metered delivery of milk which contains a roller hose pump, with which milk is sucked out of a storage container and delivered to a receptacle, which stands on a scale that is reached when it is reached a weight corresponding to a predetermined amount of milk stops the pump operation.
- a peristaltic pump avoids moving parts that come into contact with the milk and makes it possible to keep the milk in the device sterile.
- This device is, however, neither suitable nor intended for the mixing of two liquids with one another in a predetermined ratio and, furthermore, is relatively complex since it requires a balance with which the weight of the container intended for the intake of milk must first be determined, so that it is independent of the exact one Weight of this receptacle always equal amounts of milk are given when operating the device.
- the invention has for its object to provide a beverage dispenser of the type mentioned, with which two liquids of very different viscosities can be mixed together in a ratio which differs greatly from 1 and which is a predetermined amount of dispenses mixed liquids into these liquids without the weight of the vessel holding the liquid quantity having to be determined.
- the invention is based on the fact that liquid quantities can be dosed relatively precisely with peristaltic pumps. It is also based on the knowledge that the speed with which the hose of a peristaltic pump is able to regain its original shape after being compressed by a pressure roller and thus exert a suction effect in a liquid that is largely supplied without pressure from the viscosity of this liquid depends.
- the present invention makes use of this knowledge, because with it it becomes possible to use hoses of identical cross-sections and material properties for the conveyance of two liquids which have very different viscosities, because the hose which conveys the more viscous liquid, less quickly its original shape after compression, assumes than the other hose, which for example promotes water.
- the rotor in the pump which carries the pressure rollers, has to rotate several times, so that by means of the speed of the pump rotor Means are available that are able to stand up in a suitable manner, taking into account the speed at which the pump hoses are able to straighten up again after being compressed are can be selected.
- FIG. 1 shows a storage container 1 for a cocoa paste and a storage container 2 for hot water.
- the two aforementioned storage containers 1 and 2 are provided with a hose pump, designated overall by 5, which contains two pump hoses 6 and 7, which are arranged parallel to one another on the inner circumference of a cylinder 8.
- the two lines 3 and 4 are connected to the inlets of the pump tubes 6 and 7, while the outlets of these pump tubes are connected to lines 9 and 10 which lead to a mixing container 11 in which a stirrer 12 is arranged.
- the mixing container 11 has an outlet line 13 in which a valve 14 is located.
- the outlet of the valve 14 is the outlet of the beverage dispenser, under which a receptacle 15 can be arranged.
- the hose pump 5 has a rotating rotor inside, consisting of a shaft 16, which is driven by a motor 17 and which carries an arm 18, on each end of which a roller-shaped pressure roller 19 is rotatably mounted.
- the pressure rollers 19 are in engagement with the pressure hoses 6 and 7 such that they can compress the inner cross section almost or completely without damaging the hoses 6 and 7 (see Fig. 2 above).
- the pump tubes 6 and 7 are made of a material with good resilience, for example silicone rubber.
- control device 20 which can be manually excited by means of a push button 21, for example.
- the control device 20 acts on the electric motor 17 in such a way that it actuates the electric motor 17 for a predetermined period of time when the pushbutton 21 is actuated once. This time period is dimensioned such that a predetermined total amount of liquid is dispensed by the peristaltic pump 5.
- the control device 20 is connected to the stirrer 12 in order to put it into operation for a predetermined period of time when liquids are dispensed from the pump 5 to the mixing container 11.
- the control device 20 is also connected to the outlet valve 14 in order to open it in a suitable timing with the operation of the stirrer 12.
- temperature sensors 22 and 23 are arranged on the storage containers 1 and 2 and are connected to the control device 20. Both storage containers 1 and 2 have temperature control devices 24 and 25 which can be controlled by the control device 20 and ensure that predetermined temperatures are maintained in the storage containers 1 and 2.
- a peristaltic pump For dispensing a cocoa drink made from hot water and a cocoa paste in a ratio of 5: 1 is mixed together, a peristaltic pump has proven to be advantageous in which the cylinder 8 has an inner diameter of approximately 7 cm, the pump hoses consisting of silicone rubber each having an outer diameter of 9.5 mm and a wall thickness of approximately 1.75 mm and have an arc of about 320 ° in each cylinder. At speeds of the shaft 16 with the arm 18 attached to it in the range between 50 and 100 rpm, the aforementioned mixing ratio of five parts water to one part cocoa paste could be achieved with this peristaltic pump.
- the mixing container 11 For the operation of the device, it is not necessary that the total amount to be dispensed per portion is taken up by the mixing container 11, rather the mixing container can be operated in continuous operation, at least for part of the operating time. Possibly. the outlet valve 14 can also be omitted.

Abstract
Description
Die Erfindung bezieht sich auf einen Getränkespendeautomat, insbesondere Kakaospendeautomat, in dem zwei Flüssigkeiten unterschiedlicher Viskositäten in einem vorbestimmten Mengenverhältnis miteinander vermischt werden und der eine vorbestimmte Menge des aus diesen Flüssigkeiten gemischten Getränks abgibt.The invention relates to an automatic beverage dispenser, in particular an automatic cocoa dispenser, in which two liquids of different viscosities are mixed together in a predetermined quantity ratio and which dispenses a predetermined amount of the beverage mixed from these liquids.
Manche Getränke, wie insbesondere Kakao, haben einen besonderen Wohlgeschmack nur dann, wenn sie frisch zubereitet getrunken werden. Getränkespendeautomaten, die solche Getränke frisch zubereitet abgeben sollen und die beispielsweise für den Einsatz in Kantinen, Selbstbedienungsgaststätten oder dgl. vorgesehen sind, müssen daher in der Lage sein, die Grundflüssigkeit, beispielsweise heißes Wasser, und den diesem zuzusetzenden Getränkestoff, beispielsweise einen Extrakt oder Kakaopaste, in einem vorgegebenen Verhältnis miteinander zu vermischen und in genau bemessener Gesamtmenge abzugeben.Some beverages, such as cocoa in particular, only have a special pleasant taste when they are drunk freshly prepared. Vending machine for dispensing drinks, which are to deliver such drinks freshly prepared and which are intended for use in canteens, self-service restaurants or the like, for example, must therefore be able to dispense the basic liquid, for example hot water, and the beverage material to be added to it, for example an extract or cocoa paste to mix with each other in a predetermined ratio and to deliver in precisely measured total quantity.
Für die Mengenabstimmung der Getränkebestandteile sind einfache Durchflußsteuerventile wenig geeignet, da die Strömungsgeschwindigkeit der Getränkebestandteile sehr stark von der Viskosität derselben abhängt. Der Einsatz von Kolbenpumpen, mit denen eine genaue mengenmäßige Dosierung an sich möglich wäre (vgl. US-A-2 654 505), empfiehlt sich nicht, da in ihnen die Getränkebestandteile mit Schmierstoffen für die beweglichen Teile in Berührung gelangen können und dadurch ihr Geschmack beeinträchtigt wird, ganz abgesehen von Beschränkungen durch lebensmittelrechtliche Vorschriften. Auch erfordern solche Kolbenpumpen einen erheblichen Wartungsaufwand und sie neigen zum Ausfall, insbesondere wenn zwischen einzelnen Getränkeentnahmevorgängen größere Stillstandszeiten liegen, in denen Getränkebestandteile sich an Pumpenteilen absetzen und ggf. verfestigen können.Simple flow control valves are not very suitable for the quantity adjustment of the beverage components, since the flow rate of the beverage components depends very much on the viscosity of the same. The use of piston pumps, with which an exact quantitative dosage per se would be possible (cf. US-A-2 654 505), is not recommended, since in them the beverage components can come into contact with lubricants for the moving parts and thus their taste is affected entirely apart from restrictions imposed by food regulations. Piston pumps of this type also require a considerable amount of maintenance and tend to fail, particularly if there are longer downtimes between individual beverage removal processes, in which beverage constituents can settle on pump parts and possibly solidify.
Aus der DE-A-33 09 603 ist eine Vorrichtung für die dosierte Abgabe von Milch bekannt, die eine Rollen-Schlauchpumpe enthält, mit der Milch aus einem Vorratsbehälter angesaugt und an ein Aufnahmegefäß abgegeben wird, das auf einer Waage steht, die beim Erreichen eines einer vorgegebenen Milchmenge entsprechenden Gewichts den Pumpenbetrieb abbricht. Eine solche Schlauchpumpe vermeidet sich gegeneinander bewegende Teile, die mit der Milch in Berührung gelangen und ermöglicht es, die Milch in der Vorrichtung keimfrei zu halten. Diese Vorrichtung ist indessen für die Vermischung zweier Flüssigkeiten miteinander in einem vorgegebenen Verhältnis weder geeignet noch vorgesehen und außerdem relativ aufwendig, da sie eine Waage benötigt, mit der zunächst das Gewicht des für die Aufnahme der Milch bestimmten Gefäßes ermittelt werden muß, damit unabhängig vom exakten Gewicht dieses Aufnahmegefäßes bei Betätigung der Vorrichtung stets gleiche Milchmengen abgegeben werden.From DE-A-33 09 603 a device for the metered delivery of milk is known, which contains a roller hose pump, with which milk is sucked out of a storage container and delivered to a receptacle, which stands on a scale that is reached when it is reached a weight corresponding to a predetermined amount of milk stops the pump operation. Such a peristaltic pump avoids moving parts that come into contact with the milk and makes it possible to keep the milk in the device sterile. This device is, however, neither suitable nor intended for the mixing of two liquids with one another in a predetermined ratio and, furthermore, is relatively complex since it requires a balance with which the weight of the container intended for the intake of milk must first be determined, so that it is independent of the exact one Weight of this receptacle always equal amounts of milk are given when operating the device.
Der Erfindung liegt die Aufgabe zugrunde, einen Getränkespendeautomaten der eingangs genannten Art anzugeben, mit dem zwei Flüssigkeiten voneinander sehr verschiedener Viskosität in einem von 1 stark abweichenden Mengenverhältnis miteinander vermischt werden können und der eine vorbestimmte Menge des aus diesen Flüssigkeiten gemischten Getränks abgibt, ohne daß hierzu das Gewicht des die Flüssigkeitsmenge aufnehmenden Gefäßes ermittelt werden muß.The invention has for its object to provide a beverage dispenser of the type mentioned, with which two liquids of very different viscosities can be mixed together in a ratio which differs greatly from 1 and which is a predetermined amount of dispenses mixed liquids into these liquids without the weight of the vessel holding the liquid quantity having to be determined.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.
Die Erfindung geht von der Tatsache aus, daß mit Schlauchpumpen Flüssigkeitsmengen relativ genau dosiert werden können. Ihr liegt weiterhin die Erkenntnis zugrunde, daß die Geschwindigkeit, mit der der Schlauch einer Schlauchpumpe in der Lage ist, nach dem Zusammendrücken durch eine Druckrolle seine ursprüngliche Gestalt wiederzugewinnen und damit eine Saugwirkung in einer ihm weitestgehend drucklos zugeführten Flüssigkeit auszuüben, von der Viskosität dieser Flüssigkeit abhängt. Diese Erkenntnis nutzt die vorliegende Erfindung aus, denn mit ihr wird es möglich, für die Förderung zweier Flüssigkeiten, die voneinander stark unterschiedliche Viskositäten aufweisen, Schläuche übereinstimmender Querschnitte und Materialeigenschaften zu verwenden, weil jener Schlauch der die zähflüssigere Flüssigkeit fördert, weniger schnell seine ursprüngliche Gestalt nach dem Zusammendrücken annimmt, als der andere Schlauch, der beispielsweise Wasser fördert. Da in einer Schlauchpumpe dieser Art die pro Pumptakt geförderte Flüssigkeitsmenge relativ klein ist, sie beträgt typischerweise nur wenige, beispielsweise 3 bis 5 cm³, muß der Rotor in der Pumpe, der die Druckrollen trägt, mehrmals umlaufen, so daß mittels der Drehzahl des Pumpenrotors ein Mittel zur Verfügung steht, das in geeigneter Weise unter Berücksichtigung der Geschwindigkeit, mit der die Pumpenschläuche sich nach dem Zusammendrücken wieder aufzurichten in der Lage sind, gewählt werden kann.The invention is based on the fact that liquid quantities can be dosed relatively precisely with peristaltic pumps. It is also based on the knowledge that the speed with which the hose of a peristaltic pump is able to regain its original shape after being compressed by a pressure roller and thus exert a suction effect in a liquid that is largely supplied without pressure from the viscosity of this liquid depends. The present invention makes use of this knowledge, because with it it becomes possible to use hoses of identical cross-sections and material properties for the conveyance of two liquids which have very different viscosities, because the hose which conveys the more viscous liquid, less quickly its original shape after compression, assumes than the other hose, which for example promotes water. Since in a hose pump of this type the amount of liquid pumped per pump cycle is relatively small, typically only a few, for example 3 to 5 cm³, the rotor in the pump, which carries the pressure rollers, has to rotate several times, so that by means of the speed of the pump rotor Means are available that are able to stand up in a suitable manner, taking into account the speed at which the pump hoses are able to straighten up again after being compressed are can be selected.

In Fig. 1 erkennt man einen Vorratsbehälter 1 für eine Kakaopaste und einen Vorratsbehälter 2 für Heißwasser. Über Leitungen 3 und 4 sind die beiden genannten Vorratsbehälter 1 und 2 mit einer insgesamt mit 5 bezeichneten Schlauchpumpe versehen, die zwei Pumpschläuche 6 und 7 enthält, die parallel nebeneinander auf dem inneren Umfang eines Zylinders 8 angeordnet sind. Die beiden Leitungen 3 und 4 sind mit den Einlässen der Pumpschläuche 6 und 7 verbunden, während die Auslässe dieser Pumpschläuche mit Leitungen 9 und 10 verbunden sind, die zu einem Mischbehälter 11 führen, in welchem ein Rührer 12 angeordnet ist. Der Mischbehälter 11 weist eine Auslaßleitung 13 auf, in der sich ein Ventil 14 befindet. Der Ausgang des Ventils 14 ist der Auslaß des Getränkespendeautomaten, unter dem ein Aufnahmegefäß 15 angeordnet werden kann.1 shows a storage container 1 for a cocoa paste and a
Die Schlauchpumpe 5 weist im Innern einen umlaufenden Rotor auf, bestehend aus einer Welle 16, die von einem Motor 17 angetrieben ist und die einen Arm 18 trägt, an dessen beiden Enden je eine walzenförmige Druckrolle 19 drehbar gelagert ist. Die Druckrollen 19 stehen mit den Druckschläuchen 6 und 7 derart in Eingriff, daß sie dessen inneren Querschnitt fast oder vollständig zusammendrücken können, ohne dabei die Schläuche 6 und 7 zu beschädigen (siehe Fig. 2 oben).The
Die Pumpschläuche 6 und 7 bestehen aus einem Material mit gutem Rückstellvermögen, beispielsweise aus Silikongummi.The
Der Getränkespendeautomat nach Fig. 1 umfaßt ferner eine Steuereinrichtung 20, die mittels beispielsweise eines Drucktasters 21 manuell anregbar ist. Die Steuereinrichtung 20 wirkt auf den Elektromotor 17 so ein, daß sie auf einmalige Betätigung des Drucktasters 21 den Elektromotor 17 für eine vorbestimmte Zeitdauer in Betrieb setzt. Diese Zeitdauer ist so bemessen, daß von der Schlauchpumpe 5 eine vorbestimmte Flüssigkeitsgesamtmenge abgegeben wird. Fernerhin ist die Steuereinrichtung 20 mit dem Rührer 12 verbunden, um diesen für eine vorbestimmte Zeitdauer in Betrieb zu setzen, wenn von der Pumpe 5 Flüssigkeiten an den Mischbehälter 11 abgegeben werden. Weiterhin ist die Steuereinrichtung 20 auch mit dem Auslaßventil 14 verbunden, um dieses in geeigneter Zeitabstimmung mit dem Betrieb des Rührers 12 zu öffnen.1 further includes a
An den Vorratsbehältern 1 und 2 sind im vorliegenden Beispiel Temperaturfühler 22 und 23 angeordnet, die mit der Steuereinrichtung 20 verbunden sind. Beide Vorratsbehälter 1 und 2 weisen Temperiereinrichtungen 24 und 25 auf, die von der Steuereinrichtung 20 ansteuerbar sind und dafür sorgen, daß in den Vorratsbehältern 1 und 2 vorbestimmte Temperaturen aufrechterhalten werden.In the present example,
Für die Abgabe eines Kakaogetränks, das aus heißem Wasser und einer Kakaopaste im Mengenverhältnis von 5 : 1 zusammengemischt ist, hat sich eine Schlauchpumpe als vorteilhaft erwiesen, bei der der Zylinder 8 einen Innendurchmesser von etwa 7 cm hat, wobei die aus Silikongummi bestehenden Pumpschläuche jeweils einen Außendurchmesser von 9,5 mm und eine Wandstärke von etwa 1,75 mm aufweisen und in dem Zylinder einen Kreisbogen von jeweils etwa 320° einnehmen. Bei Drehzahlen der Welle 16 mit dem daran befestigten Arm 18 im Bereich zwischen 50 und 100 U/min konnte mit dieser Schlauchpumpe das vorgenannte Mischungsverhältnis von fünf Teilen Wasser zu einem Teil Kakaopaste erzielt werden.For dispensing a cocoa drink made from hot water and a cocoa paste in a ratio of 5: 1 is mixed together, a peristaltic pump has proven to be advantageous in which the
Für den Betrieb der Vorrichtung ist es nicht erforderlich, daß die pro Portion abzugebende Gesamtmenge von dem Mischbehälter 11 aufgenommen wird, vielmehr kann der Mischbehälter, wenigstens für einen Teil der Betriebszeit, im Durchlaufbetrieb betrieben werden. Ggf. kann das Auslaßventil 14 auch entfallen.For the operation of the device, it is not necessary that the total amount to be dispensed per portion is taken up by the
