Abstract
Description
Die vorliegende Erfindung betrifft einen Warenausgabeautomaten mit zumindest einem Sensor zur Erfassung mindestens einer kapazitiven Größe, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a goods issue machine with at least one sensor for detecting at least one capacitive variable, according to the preamble of claim 1.
In Getränkeautomaten und insbesondere in Kaffeemaschinen gibt es zahlreiche Sensoren, die insbesondere Füllstände, beispielsweise denjenigen eines Wassertanks, detektieren und an eine Steuerungseinrichtung übermitteln. Dabei werden insbesondere auch sogenannte kapazitive Sensoren verwendet, die auf Basis der Veränderung der Kapazität eines einzelnen Kondensators oder eines ganzen Kondensatorsystems arbeiten. Die dabei derzeit verwendeten Sensoren sind üblicherweise fest verkabelt, wobei insbesondere kapazitive Sensoren eine exakte Positionierung des zu messenden Mediums zum Sensor erfordern, um genaue und reproduzierbare Ergebnisse zu liefern. Werden dabei die Sensoren in Verbindung mit demontierbaren Komponenten eingesetzt, wie beispielsweise bei einem Wassertank oder einem Milchvorratsbehälter, so werden sehr hohe Anforderungen an die Kopplung bzw. die Ausführung der Messstelle gestellt, um oben genannte genaue und reproduzierbare Messergebnisse zu erhalten.In beverage vending machines and in particular in coffee machines, there are numerous sensors which in particular detect fill levels, for example those of a water tank, and transmit them to a control device. In particular, so-called capacitive sensors are used, which operate on the basis of the change in the capacitance of a single capacitor or a whole capacitor system. The currently used sensors are usually hardwired, and in particular capacitive sensors require an exact positioning of the medium to be measured to the sensor in order to provide accurate and reproducible results. If the sensors are used in conjunction with removable components, such as in a water tank or a milk reservoir, very high demands are placed on the coupling or the execution of the measuring point to obtain the above accurate and reproducible measurement results.
Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für einen gattungsgemäßen Warenausgabeautomaten, eine verbessert oder zumindest eine alternative Ausführungsform anzugeben, die insbesondere konstruktiv einfach aufgebaut ist und gleichzeitig Messergebnisse hoher Qualität liefert.The present invention therefore deals with the problem of providing a generic goods dispenser, an improved or at least provide an alternative embodiment, which is particularly simple in construction and simultaneously provides high-quality measurement results.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand des abhängigen Anspruchs.This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject of the dependent claim.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, einen kapazitiven Sensor in einem Warenausgabeautomaten als drahtlosen Signalübertragungschip, insbesondere als RFID-Chip auszubilden bzw. mit einem solchen zur Signalübertragung zu koppeln, wobei dieser RFID-Chip zur drahtlosen Signalübertragung in der Lage ist und dadurch direkt an der Messstelle eingebaut werden kann. Der kapazitive Sensor erfasst eine Veränderung der Kapazität eines einzelnen Kondensators oder eines ganzen Kondensatorsystems und leitet den so erfassten Messwert drahtlos weiter, beispielsweise an eine Kontroll-Steuereinrichtung oder ein Anzeigenfeld. Unter dem Begriff Warenausgabeautomat soll sowohl ein Automat zur Ausgabe von Feststoffen als auch ein Automat zur Ausgabe von Flüssigkeiten, Pasten oder Gemischen verstanden werden. Dies ist insbesondere dann von Vorteil, wenn mit dem Sensor beispielsweise der Füllstand eines abnehmbaren Wassertanks erfasst werden soll, weil in diesem Fall der drahtlose Signalübertragungschip direkt am Behälter fest montiert werden kann. Durch die drahtlose Signalübertragung mittels bestimmter Frequenzen kann darüber hinaus ein ansonsten hoher Verkabelungsaufwand innerhalb des Warenausgabeautomatens vermieden werden. Von größtem Vorteil ist jedoch, dass der als insbesondere RFID-Chip ausgebildete Sensor durch seine einmal festgelegte Lage stets richtig zum zu messenden Medium positioniert ist und dadurch besonders exakte Ergebnisse liefert.The present invention is based on the general idea of a capacitive sensor in a cash dispenser as wireless Signal transmission chip, in particular as an RFID chip form or coupled with such a signal transmission, said RFID chip for wireless signal transmission is capable of and can be installed directly at the measuring point. The capacitive sensor detects a change in the capacitance of a single capacitor or a whole capacitor system and forwards the measured value thus detected wirelessly, for example, to a control controller or a display panel. The term "goods dispenser" should be understood as meaning both an automatic dispenser for dispensing solids and an automatic dispenser for dispensing liquids, pastes or mixtures. This is particularly advantageous when the sensor, for example, the level of a removable water tank is to be detected, because in this case the wireless signal transmission chip can be mounted directly on the container. In addition, the wireless signal transmission by means of certain frequencies, an otherwise high cabling overhead within the automatic teller machine can be avoided. However, the greatest advantage is that the sensor designed as a particular RFID chip is always correctly positioned by its once fixed position to the medium to be measured, thereby providing particularly accurate results.
Bei bisherigen Sensoren, die den Füllstand beispielsweise eines abnehmbaren Wassertanks erfassen sollten, war dies nur durch eine äußert präzise Kopplung bzw. Ausführung der Messstelle möglich. Mit dem erfindungsgemäßen Signalübertragungschip ist das Problem der optimalen Relativlage zwischen diesem und dem zu messenden Medium gelöst, da der drahtlose Signalübertragungschip einmal an seiner Einbauposition angebracht und dort fixiert wird. Insbesondere ist hierbei auch vorstellbar, dass der Signalübertragungschip in eine Wandung eines Behälters, beispielsweise eines Wassertanks integriert ist und dadurch zusammen mit diesem abnehmbar und spülbar ist.In previous sensors, which should detect the level of, for example, a removable water tank, this was only possible by an extremely precise coupling or execution of the measuring point. With the signal transmission chip according to the invention, the problem of the optimal relative position between this and the medium to be measured is solved since the wireless signal transmission chip is once attached to its installation position and fixed there. In particular, in this case it is also conceivable that the signal transmission chip is integrated in a wall of a container, for example a water tank and is therefore removable and flushable together with it.
Der englische Begriff RFID (Radio Frequency Identification) bedeutet dabei im Deutschen "Identifizierung mit Hilfe von elektromagnetischen Wellen" und ermöglicht dadurch eine automatische Identifizierung bzw. Lokalisierung, beispielsweise von zu messenden Größen bzw. Gegenständen, wie beispielsweise eines Wasserstandes in einem Wassertank. Ein RFID-System besteht überlicherweise aus dem RFID-Chip (Transponder) der sich am oder im Gegenstand befindet und diesen kennzeichnet, sowie einem Lesegerät zum Auslesen der Transponderkennung. Das Lesegerät, welches im vorliegenden Fall im Getränkeautomaten integriert ist, enthält üblicherweise eine Software, die den eigentlichen Leseprozess steuert. In der Regel erzeugt dabei das Lesegerät ein elektromagnetisches Hochfrequenzfeld geringer Reichweite, vorzugsweise durch Induktionsspulen, wodurch nicht nur Daten übertragen werden können, sondern zugleich auch der RFID-Chip mit Energie versorgt werden kann. RFID-Chips können dabei so klein wie ein Reiskorn sein und dadurch an nahezu allen wichtigen Stellen des Getränkeautomatens problemlos positioniert werden.The English term RFID (Radio Frequency Identification) means in German "identification with the help of electromagnetic waves" and thereby enables automatic identification or localization, for example, to be measured sizes or objects, such as a water level in a water tank. An RFID system usually consists of the RFID chip (transponder) which is located on or in the article and identifies it, and a reader for reading the transponder identification. The reader, which is integrated in the present case in the drinks vending machine, usually contains software that controls the actual reading process. As a rule, the reader generates an electromagnetic high-frequency field of short range, preferably by induction coils, whereby not only data can be transmitted, but at the same time the RFID chip can also be supplied with energy. RFID chips can be as small as a grain of rice and thus easily positioned at almost all important points of the beverage vending machine.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist der Signalübertragungschip an zumindest einem der folgenden Behälter angeordnet und ermittelt dessen Präsenz bzw. einen Füllstand in diesem Behälter: Bohnenbehälter, Kaffeemehlbehälter, Filterkaffeebehälter, Reinigerbehälter, Milchvorratsbehälter, Satzkasten, Wassertank, Mischfluidbehälter und/oder Tropfschale. Unter Mischfluid kann hierbei insbesondere Sirup, Alkohol, Sahne, Milch, Farbstoff, etc. verstanden werden. Selbstverständlich ist ein derartiger Signalübertragungschip auch zur Erkennung von Leckagen bzw. zur Überwachung einer Funktionskontrolle (ist beispielsweise ein Schlauch/Rohr gefüllt oder nicht) einsetzbar. Bereits die Aufzählung lässt dabei erahnen, wie breit das mögliche Einsatzgebiet eines derartigen drahtlosen Signalübertragungschips im Bereich von Warenausgabeautomaten und insbesondere im Bereich von Kaffeemaschinen bzw. Kaffeevollautomaten ist.In an advantageous development of the solution according to the invention, the signal transmission chip is arranged on at least one of the following containers and determines its presence or a level in this container: bean container, ground coffee container, filter coffee container, cleaner container, milk storage container, set box, water tank, mixing fluid container and / or drip tray. In this case, mixed fluid can be understood as meaning, in particular, syrup, alcohol, cream, milk, colorant, etc. Of course, such a signal transmission chip also for the detection of leaks or for monitoring a functional control (for example, a tube / tube filled or not) can be used. Already the list suggests how wide the possible field of application of such a wireless signal transmission chip in the area of automatic teller machines and in particular in the field of coffee machines or fully automatic coffee machines.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung, bildet der wenigstens eine Signalübertragungschip einen integralen Bestandteil des Behälters. Hierbei kann der Signalübertragungschip beispielsweise in die Wandung eines Wassertanks eingelassen, insbesondere eingespritzt sein, und dadurch zusammen mit dem Wassertank entnommen bzw. auch zusammen mit diesem gespült werden. Durch die integrierte Lage des Signalübertragungschips in beispielsweise der Wandung des Behälters, ist dieser auch geschützt vor äußeren Einflüssen angeordnet, wodurch eine hohe Funktionssicherheit erreicht werden kann. Selbstverständlich ist dabei der Signalübertragungschip nicht nur auf eine kapazitive Arbeitsweise bzw. die Erfassung kapazitiver Messgrößen beschränkend anzusehen, sondern kann generell auch eine davon abweichende Arbeitsweise aufweisen.In a further advantageous embodiment of the solution according to the invention, the at least one signal transmission chip forms an integral part of the container. In this case, the signal transmission chip, for example, be embedded in the wall of a water tank, in particular injected, and thereby taken together with the water tank or flushed together with this. The integrated position of the signal transmission chip in, for example, the wall of the container, this is also protected from external influences, whereby a high reliability can be achieved. Of course, the signal transmission chip is not limited to a capacitive mode of operation or the detection of capacitive measured variables, but can generally also have a different mode of operation.
Zweckmäßig ist wenigstens ein Signalübertragungschip zur Erfassung beispielsweise eines Durchfluss, eines Drucks, einer Drehzahl, einer Wegstrecke/Entfernung, eines Feuchtegehalts, einer Dichte oder zur Erkennung von Wasserinhaltsstoffen ausgebildet. Auch diese Aufzählung lässt wiederum erkennen, dass der erfindungsgemäße Signalübertragungschip (RFID-Chip) zur Erfassung nahezu beliebiger Größen innerhalb des Getränkeautomatens, d. h. insbesondere eine Kaffeevollautomatens einer Kaffeemaschine verwendbar ist. Die Aufzählung ist dabei selbstverständlich nicht abschließend anzusehen, so dass auch weitere Größen bzw. weitere bisher nicht genannte Einbauorte für den erfindungsgemäßen Signalübertragungschip vorgesehen werden können.At least one signal transmission chip is expediently designed to detect, for example, a flow rate, a pressure, a rotational speed, a distance / distance, a moisture content, a density or the detection of water constituents. Again, this list reveals that the signal transmission chip (RFID chip) according to the invention for the detection of almost any size within the beverage dispenser, d. H. in particular a Kaffeevollautomatens a coffee machine is usable. Of course, the list is not to be considered exhaustive, so that other sizes or other previously not mentioned installation locations for the signal transmission chip according to the invention can be provided.
Mit dem erfindungsgemäßen drahtlosen Signalübertragungschip können insbesondere bei Kaffeemaschinen diejenigen Teile, die oftmals abgenommen und wieder eingesetzt werden, ausgerüstet werden, wobei der Signalübertragungschip vorzugsweise fest in oder an dem abnehmbaren Teil ein- /angebaut ist. Hierdurch wird sichergestellt, dass der Signalübertragungschip zum zu messenden Medium immer gleich positioniert ist und dadurch zuverlässig exakt reproduzierbare Ergebnisse liefert. Durch die drahtlose Signalübertragung ist es auch möglich, eine Vielzahl von insbesondere RFID-Chips von lediglich einem Lesegerät lesen zu lassen, wobei insbesondere der Verkabelungsaufwand aufgrund der drahtlosen Übertragung deutlich reduziert werden kann. Hierdurch werden die erfindungsgemäßen Getränkeautomaten nicht nur konstruktiv einfacher und kostengünstiger, sondern zugleich auch servicefreundlicher.With the wireless signal transmission chip according to the invention, in particular in coffee machines, those parts which are often removed and replaced can be equipped, the signal transmission chip preferably being fixedly mounted in or on the detachable part. This ensures that the signal transmission chip is always positioned the same way to the medium to be measured and thus reliably delivers exactly reproducible results. It is through the wireless signal transmission It is also possible to have a large number of particular RFID chips read by only one reading device, wherein in particular the wiring complexity due to the wireless transmission can be significantly reduced. As a result, the beverage vending machines according to the invention are not only structurally simpler and cheaper, but at the same time also service-friendly.
