Die Führungseinrichtungen sind entsprechend ausgebildet und weisen eine Mehrzahl von Aufnahmeöffnungen auf, die mit entsprechenden Abgabeöffnungen der Vorrats- und Dispensiereinrichtungen korrespondieren, und bei Ausrichtung der Abgabe - an den Aufnahmeöffnungen kann eine Übergabe von Arzneimittelportionen von den Vorrats- und Dispensiereinrichtungen an die Führungseinrichtungen stattfinden. Aufgrund der matrixartigen Anordnung der Vorrats- und Dispensiereinrichtungen weisen die Führungseinrichtungen eine gewisse Bauhöhe und damit ein gewisses Gewicht auf. In Abhängigkeit von der Anzahl der Führungseinrichtungen ist das Gesamtgewicht der verwendeten Führungseinrichtungen erheblich, so dass das Transportmittel der Transporteinrichtung unter einer erheblichen Spannung steht, und für den Antrieb, d. h. die Bewegung der Führungseinrichtungen, ein erheblicher Kraftaufwand erforderlich ist.The transport device for moving the guide devices along the stocking and dispensing devices has at least one transporting means to which the guide devices are fastened. This transmission means may for example be formed as a toothed belt, which is moved between a drive axle and a deflection axis and has a plurality of holders, to which the guide means are attached. The storage and dispensing devices are usually arranged in a matrix, ie a plurality of storage and dispensing devices are arranged one above the other. The guide means are designed accordingly and have a plurality of receiving openings which correspond to corresponding discharge openings of the storage and dispensing devices, and in alignment of the delivery - to the Receiving openings can take place a transfer of drug portions of the storage and dispensing to the management institutions. Due to the matrix-like arrangement of the storage and dispensing devices, the guide means have a certain height and thus a certain weight. Depending on the number of guide devices, the total weight of the guide means used is significant, so that the means of transport of the transport means is under a considerable tension, and for the drive, ie the movement of the guide means, a considerable effort is required.
Insbesondere bei Verpackungsvorrichtungen mit einer Vielzahl von Führungseinrichtungen, und der damit erforderlich Spannung auf dem Transportmittel, kann es vorkommen, dass das Transportmittel reißt. Ohne die entsprechende Gegenkraft wird das Transportmittel mit den zugehörigen Führungseinrichtungen über die Antriebsachse "führungslos" durch die Verpackungsvorrichtung gezogen, und bei dieser nicht geführten Bewegung können sich die Führungseinrichtungen innerhalb der Verpackungseinrichtung verkeilen und erheblichen Schaden in der Verpackungseinrichtung anrichten.In particular, in packaging devices with a plurality of guide devices, and the voltage required on the means of transport, it may happen that the transport breaks. Without the corresponding counterforce, the means of transport with the associated guide means is pulled over the drive axle "guidelessly" through the packaging device, and in this uncontrolled movement, the guide means can become wedged within the packaging device and cause considerable damage in the packaging device.
Aus der
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zum Betreiben einer Verpackungsvorrichtung für einzelne Arzneimittelportionen bereitzustellen, bei welchem die Gefahr der Beschädigung der Verpackungsvorrichtung bei einer Fehlfunktion eines Transportmittels der Führungseinrichtungen vermindert ist. Es ist ferner Aufgabe der vorliegenden Erfindung, eine entsprechende Verpackungsvorrichtung bereitzustellen.It is therefore an object of the present invention to provide a method for operating a packaging device for individual drug portions, wherein the risk of damage to the packaging device is reduced in a malfunction of a transport means of the guide means. It is a further object of the present invention Invention to provide a corresponding packaging device.
Die Aufgabe wird gelöst durch ein Verfahren zum Betreiben einer Verpackungsvorrichtung gemäß Patentanspruch 1. Die bei dem erfindungsgemäßen Verfahren verwendete Verpackungsvorrichtung umfasst eine Mehrzahl von Führungseinrichtungen, die an zumindest einem Transportmittel einer Transporteinrichtung befestigt sind. Erfindungsgemäß werden die Führungseinrichtungen entlang einer Mehrzahl von Vorrats- und Dispensiereinrichtungen, in denen Arzneimittelportionen gelagert werden können, bewegt, wobei Abgabeöffnungen der Vorrats- und Dispensiereinrichtungen an Aufnahmeöffnungen der Führungseinrichtungen ausgerichtet werden, wobei das zumindest eine Transportmittel der Transporteinrichtung von einer mit einem Motor gekoppelten Antriebsachse angetrieben und bei einer Umlenkachse zurückgeführt wird, wobei der Motor mit einer Steuereinrichtung gekoppelt ist.The object is achieved by a method for operating a packaging device according to
Das Transportmittel weist in Umfangsrichtung eine Mehrzahl von in vorgegebenen Abständen angeordneten Markierungen auf, und/oder die Umlenkachse weist eine Mehrzahl von in vorgegebenen Abständen angeordneten Markierungen auf.The transport means has in the circumferential direction a plurality of markings arranged at predetermined intervals, and / or the deflection axis has a plurality of markings arranged at predetermined intervals.
Erfindungsgemäß wird zumindest eine Weg- oder Zeitdifferenz (nachfolgend "Differenz") zwischen zwei Markierungen ermittelt, die ermittelte Differenz mit einem entsprechenden Sollwert verglichen, wobei der Sollwert der Differenz bei fehlerfreier Funktionsweise der Transporteinrichtung entspricht, und bei Ermittlung einer einen Schwellenwert überschreitender Abweichung zwischen dem Sollwert und der ermittelten Differenz die Antriebsachse angehalten.According to the invention, at least one distance or time difference (hereinafter "difference") is determined between two markings, the determined difference is compared with a corresponding nominal value, the nominal value corresponding to the difference in error-free operation of the transport device, and upon determination of a deviation exceeding a threshold value between the Setpoint and the difference determined the drive axle stopped.
Bei den erfindungsgemäß vorgesehenen Markierungen auf dem Transportmittel und/oder der Umlenkachse kann es sich um Markierungen handelt, die beispielswiese von einem Annäherungssensor erfasst werden, d. h. einem Sensorsystem, das ohne direkten Kontakt zu den Markierungen berührungsfrei funktioniert. In Abhängigkeit von der genauen Führung des Verfahrens und der Ausgestaltung der zur Durchführung des erfindungsgemäßen Verfahrens verwendeten Verpackungsvorrichtungen können induktive, kapazitive, magnetische oder optische Näherungssensoren verwendet werden. Alternativ können beispielsweise Lichtschranken verwendet werden, die einen Durchtritt einer Markierung erfassen. Bei fehlerfreier Transporteinrichtung bewegt sich das Transportmittel mit einer vorgegebenen Geschwindigkeit zwischen der mit dem Motor angetriebene Antriebsachse und der Umlenkachse. Dabei wendet der Motor zur Bewegung des Transportmittels eine gewisse Kraft auf, und es besteht eine gewisse Spannung in dem Transportmittel. Aufgrund der gleichmäßigen Bewegung des Transportmittels werden zwischen vorgegebenen Markierungen stets Zeitdifferenzen gemessen, die in einem gewissen Bereich um einen vorgegebenen Sollwert liegen.The markings provided on the means of transport and / or the deflection axis according to the invention may be markings which are detected, for example, by a proximity sensor, ie a sensor system which operates without contact with the markings without contact. Depending on the precise management of the method and the design of the implementation of the Inductive, capacitive, magnetic or optical proximity sensors can be used. Alternatively, it is possible, for example, to use light barriers which detect a passage of a marking. If the transport device is faultless, the means of transport moves at a predetermined speed between the drive axle driven by the motor and the deflection axle. In this case, the motor applies a certain force to the movement of the means of transport, and there is a certain tension in the means of transport. Due to the uniform movement of the means of transport are always measured between predetermined markers time differences that are within a certain range by a predetermined setpoint.
Reißt nun das Transportmittel, beispielsweise aufgrund der hohen Zugspannung, ändert sich die Bewegungsgeschwindigkeit des Transportmittels, wobei die Geschwindigkeit des Transportmittels in Abhängigkeit von dem Ort des Risses und der Erfassung der Zeitdifferenz kleiner oder größer als der Sollwert sein kann, d. h. die Geschwindigkeit des Transportmittels kann bei einem Riss ortsabhängig zu- oder abnehmen, in jedem Fall weicht die Zeitdifferenz aber von einem vorgegebenen Sollwert ab.Now tears the means of transport, for example, due to the high tensile stress, the speed of movement of the means of transport, the speed of the means of transport depending on the location of the crack and the detection of the time difference may be smaller or larger than the desired value, d. H. The speed of the means of transport may increase or decrease in a crack depending on location, but in any case the time difference deviates from a predetermined setpoint.
Sobald eine solche Abweichung registriert wird, wird die Antriebswelle angehalten, um eine weitere Bewegung des Transportmittels, und damit der Führungseinrichtungen, durch die Verpackungsvorrichtung zu verhindern.Once such a deviation is registered, the drive shaft is stopped to prevent further movement of the transport means, and thus the guide means, by the packaging device.
Die Markierungen können an dem Transportmittel selber vorgesehen sein und/oder an der Umlenkachse. Die Markierungen können beispielsweise von beabstandeten Bauteilen an der Umlenkrolle oder einem Transportmittel bereitgestellt werden. Denkbar ist auch, dass beide Markierungen von lediglich einem Bauteil bereitgestellt werden, wobei der "Anfang" und das "Ende" des Bauteils ermittelt wird. Basierend auf dem "Anfang" und dem "Ende" zugeordneten Werten kann dann die Differenz bestimmt werden.The markings can be provided on the means of transport itself and / or on the deflection axis. The markings may for example be provided by spaced components on the deflection roller or a transport means. It is also conceivable that both markings are provided by only one component, wherein the "beginning" and the "end" of the component is determined. Based on the values assigned to the "beginning" and the "end", the difference can then be determined.
Auch die Zeitdifferenz zwischen zwei vorgegebenen Markierungen der Umlenkachse wird sich bei einem Riss des Transportmittels ändern, d. h. die Umdrehungsgeschwindigkeit wird sich ändern, so dass auch anhand der Markierungen an der Umlenkachse ein solcher Riss detektiert werden kann.Also, the time difference between two predetermined markings of the deflection axis will change at a crack of the means of transport, d. H. the rotational speed will change, so that such a crack can also be detected on the basis of the markings on the deflection axis.
Alternativ zu der Ermittlung einer Zeitdifferenz zwischen zwei Markierungen kann die Wegdifferenz zwischen zwei Markierungen ermittelt werden. Dazu werden Positionswerte des Motos und / oder der Antriebsachse genutzt.As an alternative to determining a time difference between two markings, the path difference between two markings can be determined. Position values of the motor and / or the drive axis are used for this purpose.
Der mit der Antriebsachse gekoppelte Motor führt für eine vollständige Umdrehung der Antriebsachse eine vorgegebene Anzahl von Drehschritten (Schrittanzahl pro Umdrehung) aus, wobei die aktuelle Position mit jedem Drehschritt erhöht wird. Nach Vollendung einer vollständigen Umdrehung kann die aktuelle Position (des Motors und / oder der Antriebsachse) auf null gesetzt werden, alternativ kann sie einfach ohne Rücksetzen stets weiter erhöht werden kann.The motor coupled to the drive axle carries out a predetermined number of rotation steps (number of steps per revolution) for a complete revolution of the drive axle, the current position being increased with each rotation step. After completion of a complete revolution, the current position (of the motor and / or the drive axle) can be set to zero, alternatively it can easily be increased further without resetting.
Zur Ermittlung der Wegdifferenz werden die aktuelle Position (des Motors oder der Antriebsachse) bei dem Erfassen der ersten Markierung und die aktuelle Position (des Motors oder der Antriebsachse) bei dem Erfassen der zweiten Markierung verglichen. Bei einer fehlerfreien Funktionsweise der Transporteinrichtung entspricht die ermittelte Differenz (unter Berücksichtigung einer bestimmten Fehlertoleranz) stets dem Sollwert. Bei Fehlfunktion ergibt sich eine Abweichung bedingt durch eine Verlangsamung oder Beschleunigung der Umlenkachse oder eines Transportmittels. Verlangsamt sich beispielsweise das Transportmittel werden zwischen zwei Markierungen mehr Drehschritte ermittelt als üblich, da sich der Motor und die Antriebsachse "normal" weiterbewegen, die Markierungen sich aber langsamer bewegen und so mehr Drehschritte vergangen sind bevor die zweite Markierung erfasst wird.In order to determine the path difference, the current position (of the motor or the drive axle) in the detection of the first mark and the current position (of the motor or the drive axle) are compared in the detection of the second mark. In a faultless operation of the transport device, the determined difference (taking into account a specific error tolerance) always corresponds to the desired value. In case of malfunction, a deviation results due to a slowing down or acceleration of the deflection axis or a means of transport. If, for example, the means of transport slows down more rotational steps are detected between two markings than usual, since the motor and the drive axis continue to move "normally", but the markers move more slowly and thus more turning steps have passed before the second mark is detected.
Bei dem erfindungsgemäßen Verfahren wird die Bewegung der Führungseinrichtungen durch die Verpackungsvorrichtung automatisch angehalten wenn eine Fehlfunktion der Transporteinrichtung ermittelt wird, wobei erfindungsgemäß diese Fehlfunktion anhand von Abweichungen einer Differenz zwischen zwei Markierungen, die an dem Transportmittel und/oder der Umlenkrolle vorgesehen sind, ermittelt wird.In the method according to the invention, the movement of the guide means by the packaging device is automatically stopped when a malfunction of the transport device is determined, according to the invention this Malfunction based on deviations of a difference between two marks, which are provided on the transport means and / or the deflection roller, is determined.
Umfasst die Verpackungsvorrichtung zur Durchführung des erfindungsgemäßen Verfahrens lediglich ein Transportmittel, kann die Differenz zwischen zwei vorgegebenen Markierungen an dem Transportmittel oder zwei Markierungen an der Umlenkachse erfasst werden.If the packaging device for carrying out the method according to the invention comprises only one means of transport, the difference between two predetermined markings on the means of transport or two markings on the deflection axis can be detected.
Wenn lediglich ein Transortmittel vorhanden ist kann es jedoch vorkommen, dass eine zweite Markierung nie erreicht wird, nämlich dann, wenn die Fehlfunktion dazu führt, dass das Transportmittel abrupt stoppt. Zwar ist ein derart abrupter Stopp unwahrscheinlich, um diesen aber dennoch ermitteln zu können ist es bei einer bevorzugten Ausführungsform vorgesehen, dass bei der Ermittlung der Weg- oder Zeitdifferenz zwischen zwei Markierungen die Ermittlung nach Überschreiten eines vorgegebenen Abbruchwertes beendet wird und die Antriebsachse angehalten wird. Dieser Abbruchwert kann beispielsweise der Summe aus Sollwert und Schwellenwert entsprechen. Es können aber auch andere Werte vorgegeben werden. In jedem Fall ist sichergestellt, dass die Steuereinrichtung in einem oben geschilderten Fall nicht "zu lange" auf die Ermittlung der zweiten Markierung wartet. Auch in einem solchen Fall ist also gewährleistet, dass die Transportvorrichtung nach einer gewissen Zeit oder Drehzahl der Antriebsachse oder des Motors abgestoppt wird, um Schäden innerhalb der Vorrichtung zu vermeiden.However, if only one means of transmission is present, it may happen that a second mark is never reached, namely when the malfunction causes the means of transport to abruptly stop. Although such an abrupt stop is unlikely, but in order to be able to determine it, it is provided in a preferred embodiment that when determining the distance or time difference between two markings, the determination is terminated after exceeding a predetermined Abbruchwertes and the drive shaft is stopped. This abort value can correspond, for example, to the sum of the set value and the threshold value. However, other values can also be specified. In any case, it is ensured that the control device does not wait too long for the determination of the second mark in a case described above. Even in such a case, it is thus ensured that the transport device is stopped after a certain time or rotational speed of the drive axle or of the engine in order to avoid damage within the device.
Umfasst die Vorrichtung zumindest zwei Transportmittel, was aufgrund der Höhe der Führungseinrichtungen bevorzugt ist, kann die Differenz zwischen zwei Markierungen desselben Transportmittels ermittelt werden. Alternativ ist es denkbar, die Differenz zwischen zwei vorgegebenen Markierungen zu ermitteln, die an unterschiedlichen Transportmitteln angeordnet sind, d. h. zwischen einer ersten Markierung an einem ersten Transportmittel und einer zweiten Markierung an einem zweiten Transportmittel. Bei Ermittlung der Differenz zwischen zwei Markierungen an unterschiedlichen Transportmitteln kann nicht nur der Riss eines Transportmittels ermittelt werden, bei welchem die Differenz schlagartig von dem Sollwert abweicht, es kann auch ein langsamer Schlupf bei einem der Transportmittel ermittelt werden, der zu einer langsamen Schiefstellung der Führungseinrichtungen führen kann, was wiederum dazu führen kann, dass sich die Führungseinrichtungen in der Transporteinrichtung verhaken und diese mehr oder weniger stark beschädigen.If the device comprises at least two transport means, which is preferred on account of the height of the guide means, the difference between two markings of the same transport means can be determined. Alternatively, it is conceivable to determine the difference between two predetermined markings which are arranged on different transport means, ie between a first mark on a first transport means and a second mark on a second transport means. When determining the difference between two marks on different means of transport can not Only the crack of a means of transport can be determined, in which the difference deviates abruptly from the desired value, it can also be determined a slow slip in one of the means of transport, which can lead to a slow misalignment of the guide means, which in turn can lead to that Hooking guide devices in the transport device and damage them more or less.
Da die bei Auftreten eines Risses eines Transportmittels auftretenden Schäden innerhalb der Verpackungsvorrichtung erheblich ausfallen können, ist es bei einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens, bei welchem die Transporteinrichtung mehrere Transportmittel umfasst, vorgesehen, dass Differenzen zwischen zwei Markierungen von zumindest zwei Transportmitteln ermittelt werden, die ermittelten Differenzen mit einem entsprechenden Sollwert und/oder miteinander verglichen werden, wobei der Sollwert der Differenz bei fehlerfreier Funktionsweise der Transporteinrichtung entspricht, und bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung zwischen einem Sollwert und einer ermittelten Differenz oder zwischen den Differenzen selber die Antriebsachse angehalten wird. Bei dieser besonderen Ausführungsform werden also die Differenzen zwischen Markierungen bei beiden Transportmitteln überwacht, so dass der Riss einer der beiden Transportmittel sehr rasch erfasst werden kann. Alternativ oder zusätzlich können auch die Differenzen selber verglichen werden. Diese sind bei einer fehlerfreien Funktionsweise der Transporteinrichtungen (und bei entsprechender Wahl der Markierungen) annähernd gleich und weisen lediglich eine geringfügige Abweichung voneinander auf. Reißt eines der Transportmittel, weichen auch die Differenzen zwischen zwei vorgegebenen Markierungen an den Transportmitteln voneinander ab, so dass auch dieser Wert genutzt werden kann, die Verpackungsvorrichtung anzuhalten.Since the damage occurring during the occurrence of a tear of a means of transport within the packaging device can be considerable, it is provided in a preferred embodiment of the method according to the invention, in which the transport device comprises several means of transport, that differences between two markings of at least two transport means are determined determined differences with a corresponding setpoint and / or compared with each other, wherein the setpoint corresponds to the difference in error-free operation of the transport device, and when determining a threshold exceeding a deviation between a setpoint and a detected difference or between the differences themselves the drive axis is stopped. In this particular embodiment, therefore, the differences between markings are monitored in both means of transport, so that the crack of one of the two means of transport can be detected very quickly. Alternatively or additionally, the differences themselves can be compared. These are approximately the same in a faultless operation of the transport devices (and with an appropriate choice of the marks) and have only a slight deviation from each other. If one of the transport means tears, the differences between two predefined markings on the means of transport also deviate from one another, so that this value can also be used to stop the packaging device.
Erfindungsgemäß ist es vorgesehen, dass bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung die Antriebsachse angehalten wird. Bei einer bevorzugten Ausführungsform ist es darüber hinaus vorgesehen, dass bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung die Antriebsachse und die Umlenkachse angehalten werden. In Abhängigkeit von der genauen Ausgestaltung der Umlenkachse und der Transportmittel ist aufgrund der zumindest herrschenden Reibung zwischen der Oberfläche der Umlenkachse und der Oberfläche des Transportmittels dadurch gewährleistet, dass das Transportmittel auch im Bereich der Umlenkachse angehalten wird, was insbesondere bei Verpackungsvorrichtungen, die sehr lange Transportmittel aufweisen, vorteilhaft ist.According to the invention, when determining a deviation exceeding a threshold, the Drive axle is stopped. In a preferred embodiment, it is further provided that when determining a deviation exceeding a threshold, the drive axle and the deflection axis are stopped. Depending on the exact configuration of the deflection axis and the transport means is due to the at least prevailing friction between the surface of the deflection axis and the surface of the transport ensured by the fact that the transport is stopped in the deflection axis, which is particularly for packaging devices, the very long transport have, is advantageous.
Zum Anhalten der Umlenkachse kann diese eine einfache Sperre aufweisen, die von der Steuereinrichtung ausgelöst wird, wenn eine einen Schwellenwert überschreitende Abweichung ermittelt wird.To stop the deflection axis, this may have a simple lock, which is triggered by the control device when a deviation exceeding a threshold is determined.
Bei einer weiteren bevorzugten Ausführungsform, bei welcher die Transporteinrichtung zumindest eine Transportmittelführung aufweist, ist es vorgesehen, dass bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung darüber hinaus die Bewegung eines Transportmittels bei der zumindest einen Transportmittelführung angehalten wird. Eine entsprechende Ausführung des erfindungsgemäßen Verfahrens bietet sich insbesondere dann an, wenn sehr lange Transportmittel verwendet werden, da bei diesen eine horizontale Unterstützung ggf. notwendig sein kann. Die Transportmittelführung, die in Eingriff mit dem von ihr geführten Transportmittel steht, sei es durch lediglich Reibung oder beispielsweise über eine Zahnung an der Innenfläche des Transportmittels und bei der Transportmittelführung, kann bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung bremsend auf das Transportmittel einwirken, wodurch die Beschädigung der Verpackungsvorrichtung weiter vermindert wird.In a further preferred embodiment, in which the transport device has at least one transport means guide, it is provided that, upon determination of a deviation exceeding a threshold, the movement of a transport means is stopped at the at least one transport means guide. A corresponding embodiment of the method according to the invention is particularly suitable when very long means of transport are used, as in these horizontal support may possibly be necessary. The transport means guide, which is in engagement with the guided by her means of transport, either by friction or for example via a toothing on the inner surface of the means of transport and in the transport guide can act on determination of a threshold exceeding divergence braking on the means of transport, whereby the Damage to the packaging device is further reduced.
Wie bereits angedeutet, kann die Differenz zwischen den erfindungsgemäß vorgesehenen Markierungen mit einer Vielzahl von Sensorsystemen ermittelt werden, wobei die Wahl von der genauen Ausführung der Verpackungsvorrichtung abhängig ist. Die verwendbaren Sensorsysteme sind dem Fachmann bekannt, so dass hier auf eine nähere Beschreibung verzichtet wird. Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens ist es vorgesehen, dass die Markierungen der Umlenkachse durch Zähne einer Umlenkrolle der Umlenkachse bereitgestellt werden. Zwar bevorzugt die Verwendung einer Umlenkrolle die Verwendung eines Transportmittels mit einer entsprechenden Zahnung, dies ist jedoch im Hinblick auf die Notwendigkeit des Antriebes des Transportmittels regelmäßig der Fall. Durch die Verwendung der Zähne der Umlenkrolle als Markierungen ist es nicht notwendig, weitere Markierungen, neben den bereits vorhandenen, vorzusehen. Bei einer weiteren Ausführungsform ist es entsprechend vorgesehen, dass die Markierungen eines Transportmittels durch Zähne an einer Zahnung des Transportmittels bereitgestellt werden, wobei die Zähne mit Zähnen einer Umlenkrolle der Umlenkachse zusammenwirken können, wobei dies jedoch nicht unbedingt erforderlich ist.As already indicated, the difference between the inventively provided markings can be determined with a variety of sensor systems, the choice of the exact execution of the packaging device is dependent. The usable sensor systems are known in the art, so that will be omitted here for a more detailed description. In a preferred embodiment of the method according to the invention, it is provided that the markings of the deflection axis are provided by teeth of a deflection roller of the deflection axis. Although the use of a pulley prefers the use of a means of transport with a corresponding toothing, but this is the case regularly in view of the need for the drive of the means of transport. By using the teeth of the guide roller as markers, it is not necessary to provide additional markings, in addition to the already existing. In a further embodiment, it is accordingly provided that the markings of a transport means are provided by teeth on a toothing of the transport means, wherein the teeth can cooperate with teeth of a deflection roller of the deflection axis, but this is not absolutely necessary.
Die erfindungsgemäß verwendeten Markierungen zur Ermittlung einer Weg- oder Zeitdifferenz können von einem Zahn (Anfang und Ende des Zahnes) oder zwei Zähnen bei der Umlenkrolle oder dem Transportmittel bereitgestellt werden.The markers used according to the invention for determining a path or time difference can be provided by a tooth (beginning and end of the tooth) or two teeth in the deflection roller or the transport means.
Bedingt durch die matrixartige Anordnung der Vorrats- und Dispensiereinrichtungen werden die Führungseinrichtungen senkrecht durch die Verpackungsvorrichtung geführt, und aufgrund der Notwendigkeit der Bewegung der Führungseinrichtungen an dem zumindest einen Transportmittel, weisen diese, zumindest im Bereich der Umlenkachse, einen gewissen Abstand voneinander auf. Bei fehlerfreier Funktionsweise der Transporteinrichtung werden die Führungseinrichtungen parallel nebeneinander durch die Verpackungsvorrichtung geführt. Eine Schiefstellung der Führungseinrichtungen deutet auf eine Fehlfunktion hin, die durch einen Schlupf bei einem der Transportmittel, sollten mehrere verwendet sein, oder durch den Riss eines Transportmittels bedingt ist. Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens ist es vorgesehen, dass die Markierungen eines Transportmittels durch Kanten von an dem Transportmittel befestigten Führungseinrichtungen bereitgestellt werden. Dabei bilden jeweils zwei Kanten einer Führungseinrichtung eine Markierung. Wenn die Differenz zwischen den zwei Markierungen beispielsweise mit einer Lichtschranke gemessen wird, kann die Lücke zwischen zwei parallelen Führungseinrichtungen zur Messung der Differenz genutzt werden. Bei einer gleichmäßigen vertikalen Ausrichtung der Führungseinrichtung an dem zumindest einem Transportmittel sind die vertikalen, parallelen Zwischenräume zwischen den Führungseinrichtungen, unter Berücksichtigung gewisser baulich bedingter Abweichungen, sehr ähnlich, so dass die Differenzen nicht wesentlich voneinander abweichen. Bei Auftreten einer Schiefstellung der Führungseinrichtungen, bedingt durch einen Schlupf an einem Transportmittel oder den Riss eines Transportmittels, kann mit der Messeinrichtung, bedingt durch die veränderte Ausrichtung des Freiraumes, nur eine andere Differenz gemessen werden, und sofern die Abweichung zu dem Sollwert einen Schwellenwert überschreitet, kann dies zur Ermittlung einer Fehlfunktion der Transporteinrichtung genutzt werden, was erfindungsgemäß zu einem Anhalten der Antriebsachse führt.Due to the matrix-like arrangement of the storage and dispensing devices, the guide devices are guided vertically through the packaging device, and due to the necessity of movement of the guide means on the at least one transport means, they have, at least in the region of the deflection axis, a certain distance from each other. If the transport device functions correctly, the guide devices are guided parallel to one another through the packaging device. A misalignment of the guide means indicates a malfunction caused by a slippage in one of the means of transport, should several be used, or by the rupture of a means of transport. In a preferred embodiment of the method according to the invention, it is provided that the markings of a means of transport Edges are provided by guide means attached to the means of transport. In each case, two edges of a guide device form a mark. If the difference between the two markings is measured, for example with a light barrier, the gap between two parallel guide means can be used to measure the difference. With a uniform vertical orientation of the guide means on the at least one transport means, the vertical, parallel spaces between the guide means, taking into account certain structurally related deviations, very similar, so that the differences do not differ significantly from each other. When a misalignment of the guide means due to a slip on a means of transport or the crack of a means of transport can be measured with the measuring device, due to the changed orientation of the free space, only another difference, and if the deviation from the setpoint exceeds a threshold , This can be used to determine a malfunction of the transport device, which leads according to the invention to a stop of the drive axle.
Die Erfindung wird ferner gelöst durch eine Verpackungsvorrichtung gemäß Patentanspruch 8. Die erfindungsgemäße Verpackungsvorrichtung umfasst eine Mehrzahl von Vorrats- und Dispensiereinrichtungen, in denen jeweils eine Art von Arzneimittelportionen gelagert ist, und eine Transporteinrichtung mit zumindest einem Transportmittel, wobei das zumindest eine Transportmittel der Transporteinrichtung von einer mit einem Motor gekoppelten Antriebsachse angetrieben und bei einer Umlenkachse zurückgeführt ist, wobei der Motor mit einer Steuereinrichtung gekoppelt ist.The invention is further achieved by a packaging device according to
Die Verpackungsvorrichtung umfasst ferner eine Mehrzahl von Führungseinrichtungen, die, ggf. lösbar, an dem zumindest einen Transportmittel befestig sind und die eine Mehrzahl von Aufnahmeöffnungen aufweisen, die bei einer Bewegung der Führungseinrichtungen an Abgabeöffnungen der Vorrats- und Dispensiereinrichtungen ausgerichtet bzw. vorbeibewegt werden, und zumindest eine Verpackungseinrichtung, der über die Führungseinrichtungen Arzneimittelportionen zugeführt werden. Diese Verpackungseinrichtung überführt die Arzneimittelportionen üblicherweise in die bereits oben beschriebenen Blisterbeutel. Die Verpackungseinrichtung kann innerhalb der Verpackungsvorrichtung angeordnet sein, alternativ ist es auch möglich, dass die Verpackungseinrichtung in einem Bauteil angeordnet ist, was von der eigentlichen Verpackungsvorrichtung separiert ist.The packaging device further comprises a plurality of guide means, which, if necessary detachably, are fastened to the at least one transporting means and which have a plurality of receiving openings which, upon movement of the guide means, are located at delivery openings of the supply and Dispensiereinrichtungen be aligned or moved past, and at least one packaging device, which are supplied via the guide means drug portions. This packaging device usually transfers the medicament portions into the blister packs already described above. The packaging device may be arranged inside the packaging device, alternatively it is also possible that the packaging device is arranged in a component, which is separated from the actual packaging device.
Erfindungsgemäß weist das Transportmittel in Umfangsrichtung und/oder die Umlenkachse Markierungen auf, und die Verpackungsvorrichtung umfasst zumindest ein mit der Steuereinrichtung gekoppeltes Sensorsystem, mit welchem Weg- oder Zeitdifferenzen (nachfolgend "Differenzen") zwischen zwei Markierungen ermittelt werden können. Bei diesen zwei Markierungen kann es sich, wie bereits unter Bezugnahme auf das Verfahren ausgeführt wurde, um zwei Markierungen an der Umlenkachse, zwei Markierungen an einem Transportmittel oder um zwei Markierungen handeln, von denen jeweils eine bei einem Transportmittel angeordnet ist.According to the invention, the transport means in the circumferential direction and / or the deflection axis markings, and the packaging device comprises at least one sensor system coupled to the control device, with which path or time differences (hereinafter "differences") between two markings can be determined. These two markings may be, as already explained with reference to the method, two markings on the deflection axis, two markings on a means of transport, or two markings, one of which is arranged on a means of transport.
Die Steuereinrichtung ist erfindungsgemäß derart ausgebildet, dass die ermittelte Differenz mit einem Sollwert vergleichbar ist, wobei der Sollwert der Differenz bei fehlerfreier Transporteinrichtung entspricht, und dass die Steuereinrichtung bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung die Antriebsachse anhält.The control device according to the invention is designed such that the determined difference is comparable to a desired value, wherein the desired value corresponds to the difference in error-free transport device, and that the control device stops the drive axle upon determination of a deviation exceeding a threshold deviation.
Bei dem Sensorsystem kann es sich beispielsweise um einen beliebigen Annäherungssensor handeln, wobei die genaue Ausgestaltung des Sensorsystems wiederum von der Ausgestaltung der Verpackungsvorrichtung als solcher abhängig ist. Als Sensorsysteme kommen beispielsweise die bereits unter Bezugnahme auf das Verfahren beschriebenen Sensorsysteme in Frage.By way of example, the sensor system can be any proximity sensor, the exact configuration of the sensor system in turn being dependent on the design of the packaging device as such. As sensor systems, for example, the sensor systems already described with reference to the method in question.
Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Verpackungsvorrichtung weist die Transporteinrichtung zumindest zwei Transportmittel auf, wobei den zumindest zwei Transportmitteln jeweils ein Sensorsystem zugeordnet ist, mit welchem eine Differenz zwischen zwei Markierungen eines Transportmittels bestimmbar ist, wobei die Steuereinrichtung bei dieser Ausführungsform derart ausgebildet ist, dass die ermittelten Differenzen mit einem Sollwert und/oder miteinander vergleichbar sind, und dass die Steuereinrichtung bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung die Antriebsachse anhält. Bei dieser Ausführungsform werden die beiden Transportmittel hinsichtlich eines Risses überwacht, so dass es gewährleistet ist, dass Beschädigungen, basierend auf einem Riss eines Transportmittels, soweit wie möglich verhindert werden. Alternativ oder zusätzlich können die Abweichungen der beiden ermittelten gleichartigen Differenzen (also zwei Wegdifferenzen oder zwei Zeitdifferenzen) voneinander berücksichtigt werden, wobei dies die Sicherheit weiter steigern kann.In a preferred embodiment of the packaging device according to the invention, the transport device has at least two transport means, wherein the at least two Transport means are each assigned a sensor system, with which a difference between two markings of a means of transport can be determined, wherein the control device is designed in this embodiment such that the differences are compared with a desired value and / or with each other, and that the control device upon determination of a deviation exceeding the threshold stops the drive axle. In this embodiment, the two transportation means are monitored for a crack, so that it is ensured that damages based on a tear of a transportation means are prevented as much as possible. Alternatively or additionally, the deviations of the two similar differences determined (that is, two path differences or two time differences) can be taken into account, which can further enhance safety.
Bei einer bevorzugten Ausführungsform umfasst die erfindungsgemäße Verpackungsvorrichtung zumindest eine mit der Steuereinrichtung gekoppelte Transportmittelführung, welche bei Ermittlung einer einen Schwellenwert überschreitenden Abweichung die Bewegung eines Transportmittels anhalten kann. Die Transportmittelführung kann somit ebenfalls dazu beitragen, dass die Transportmittel schnell und zuverlässig bei Ermittlung eines Risses angehalten werden, wodurch Beschädigungen in der Verpackungsvorrichtung vermieden werden.In a preferred embodiment, the packaging device according to the invention comprises at least one transport means guide which is coupled to the control device and which can stop the movement of a transport means when a deviation exceeding a threshold value is determined. The transport means guide can thus also contribute to the transport being stopped quickly and reliably upon detection of a crack, whereby damage in the packaging device can be avoided.
Bei einer bevorzugten Ausführungsform werden die Markierungen der Umlenkachse durch Zähne einer Umlenkrolle der Umlenkachse bereitgestellt. Erfindungsgemäß ist es bei dieser Ausführungsform also vorgesehen, dass als Markierungen Bauteile verwendet werden, die sowieso zum Betrieb der Transporteinrichtung vorgesehen sind, d. h. keine zusätzlichen Bauteile zum Bereitstellen der Markierungen notwendig sind.In a preferred embodiment, the markings of the deflection axis are provided by teeth of a deflection roller of the deflection axis.

Unter der Transporteinrichtung 100 ist eine Sammel-Transporteinrichtung 200 angeordnet, die ebenfalls ein Transportmittel 190 umfasst, welches bei der gezeigten Ausführungsform auch als umlaufender Transportriemen ausgebildet ist. Dieser Transportriemen wird über eine Antriebsrolle 143 angetrieben, die ebenfalls von der unter Bezugnahme auf Transporteinrichtung 100 beschriebenen Antriebsachse 140 angetrieben wird. Das Transportmittel 190 umfasst eine Mehrzahl von Befestigungsmitteln 192, an denen jeweils eine Sammeleinrichtung 90 angeordnet ist.Under the transport device 100 a collecting
Bei der gezeigten Ausführungsform sind die Antriebsrolle 143 der Sammel-Transporteinrichtung 200 und die Antriebsrollen 141, 142 der Transporteinrichtung 100 an der gleichen Antriebsachse 140 befestigt, so dass die Transportmittel der Transporteinrichtung 100 sowie der Sammel-Transporteinrichtung 200 (bei Annahme eines gleichen Radius der Antriebsrollen) mit gleicher Geschwindigkeit bewegt werden. Die Befestigungsmittel 112, 122, 192 der Transportmittel der beiden Transporteinrichtungen sind so ausgerichtet, dass die Sammeleinrichtungen 90 unterhalb der Führungseinrichtungen bewegt werden, d. h. die bei den Vorrats- und Dispensiereinrichtungen 20 in die Führungseinrichtung 10 abgegebenen Arzneimittelportionen werden an die unter den Führungseinrichtungen angeordneten und mit gleicher Geschwindigkeit bewegten Sammeleinrichtungen übergeben.In the embodiment shown, the

Im "linken" Abschnitt der ersten Ausführungsform der erfindungsgemäßen Verpackungsvorrichtung ist unter der Sammel-Transporteinrichtung 200 eine Verpackungseinrichtung 50 angeordnet. Bei der Verpackungseinrichtung werden die in den Sammeleinrichtungen 90 aufgenommenen Arzneimittelportionen verblistert und als ein Blisterschlauch 51 aus der Verpackungsvorrichtung hinausgeführt.In the "left" section of the first embodiment of the packaging device according to the invention is below the collecting
Um einen Riss eines Transportmittels rasch erkennen zu können, umfasst die Verpackungsvorrichtung bei der gezeigten Ausführungsform drei Sensorsysteme 60, 70, 80. Mit dem bei dem vertikalen Stützelement 3a angeordneten Sensorsystem 80 können Differenzen zwischen zwei vorgegebenen Markierungen 121 des Transportmittels 120 erfasst werden. Entsprechendes gilt für das Sensorsystem 70, das bei dem oberen horizontalen Stützelement 2a angeordnet ist. Mit dem Sensorsystem 60, das im Bereich der Umlenkrolle 151 bei dem oberen Stützelement 2a angeordnet ist, können Differenzen zwischen zwei vorgegebenen Markierungen der Umlenkrolle 151 der Umlenkachse 150 ermittelt werden. Als Markierungen kommen dabei die Zähne selber (die Differenz zwischen zwei Zähnen) oder zwei Punkte eines Zahnes (Anfang und Ende des Zahns und Differenz dazwischen) in Frage. Wie bereits beschrieben, werden die ermittelten Differenzen von der Steuereinrichtung mit Sollwerten verglichen, und sobald eine einen Schwellenwert überschreitende Abweichung festgestellt wird, werden die beiden Transportmittel 110, 120 über die Antriebsachse 140 angehalten.In order to be able to quickly recognize a tear of a means of transport, the packaging device in the embodiment shown comprises three
Die zweite Ausführungsform entspricht weitgehend der ersten Ausführungsform, lediglich die Anordnung der Sensorsysteme 60, 70, 80 unterscheidet sich geringfügig, wobei bei dieser Ausführungsform zwei Sensorsysteme, nämlich die Sensorsysteme 70, 80, bei dem vertikalen Stützelement 3a angeordnet sind.The second embodiment largely corresponds to the first embodiment, only the arrangement of the
Bei
Bei der ersten sowie der zweiten Ausführungsform sind jeweils drei Sensorsysteme vorgesehen, wobei zwei von diesen Zeitdifferenzen zwischen Markierungen der Transportmittel und eine Differenz von Markierungen bei der Umlenkachse bzw. -rolle erfassen. Bei alternativen Ausführungsformen ist denkbar, dass lediglich ein Sensorsystem verwendet wird, insbesondere dann, wenn eine Transporteinrichtung mit lediglich einem Transportmittel vorgesehen ist. Wie bereits angedeutet, ist es aufgrund der Länge der Führungseinrichtungen 10 jedoch üblich, dass zumindest zwei Transportmittel verwendet werden. Ferner ist die bei den beiden gezeigten Ausführungsbeispielen dargestellte Sammel-Transporteinrichtung für die Erfindung nicht wesentlich, sondern wurde lediglich beispielhaft dargestellt. So ist es auch denkbar, dass die umlaufenden Führungseinrichtungen alle bei einem bestimmten Punkt in der Verpackungsvorrichtung die gesammelten Arzneimittelportionen an eine weitere Einrichtung abgegeben, über welche diese einer Verpackungseinrichtung zugeführt werden.In the first and the second embodiment, three sensor systems are provided in each case, wherein two of these time differences between markings of the means of transport and a difference of markings in the deflection axis or roller detect. In alternative embodiments, it is conceivable that only one sensor system is used, in particular when a transport device is provided with only one means of transport. However, as already indicated, it is common due to the length of the guide means 10 that at least two means of transport are used. Furthermore, the collective transport device shown in the two embodiments shown is not essential to the invention, but has been shown by way of example only. Thus, it is also conceivable that the circulating guide devices all at a certain point in the packaging device, the collected drug portions delivered to another device via which they are supplied to a packaging device.
Rein praktisch verhält es sich beispielsweise so, dass der Anfang eines Zahns (erste Markierung) von dem entsprechenden Sensorsystem als positive Flanke und das Ende des Zahns als negative Flanke registriert wird. Zwischen diesen Flanken wird eine Zeitdifferenz oder eine Wegdifferenz bestimmt, wobei zur Ermittlung der Wegdifferenz die Position des Motors oder der Antriebsachse zum Zeitpunkt der positiven und der negativen Flanke herangezogen wird.In practical terms, for example, the beginning of a tooth (first marking) is registered by the corresponding sensor system as a positive flank and the end of the tooth as a negative flank. Between these flanks becomes determines a time difference or a path difference, wherein the position of the motor or the drive axis at the time of the positive and the negative edge is used to determine the path difference.
Lediglich angedeutet ist in dieser Darstellung, dass an dem äußeren Umfang des Transportmittels 110 Führungseinrichtungen 10 angeordnet sind, die auch bei dieser Darstellung in der Übergabestellung in Bezug auf die Vorrats- und Dispensiereinrichtungen 20 dargestellt sind. Bei dieser Darstellung ist ebenfalls eine Abgabeöffnung 21 einer Vorrats- und Dispensiereinrichtung 20 angedeutet.Only indicated in this illustration is that guide means 10 are arranged on the outer circumference of the transport means 110, which are also shown in this illustration in the transfer position with respect to the storage and dispensing
Bei dieser Ausführungsform ist unter der eigentlichen Transporteinrichtung wieder die Sammel-Transporteinrichtung mit einem Transportmittel 190, an welchem eine Mehrzahl von Sammeleinrichtungen 90 angeordnet ist, vorgesehen. Wie zu erkennen ist, sind die Sammeleinrichtungen 90 an den Führungseinrichtungen 10 ausgerichtet, und aufgrund der Tatsache, dass das Transportmittel 190 der Sammel-Transporteinrichtung sowie die beiden Transportmittel 110, 120 der eigentlichen Transporteinrichtung über dieselbe Antriebsachse 140 mit gleichgroßen Antriebsrollen bewegt werden, bewegen sich die Sammeleinrichtungen 90 mit der gleichen Geschwindigkeit wie die Führungseinrichtungen 10, so dass in dem Bereich, in welchem sich die Transporteinrichtung über der Sammel-Transporteinrichtung erstreckt, stets Arzneimittelportionen von der Führungseinrichtung in die Sammeleinrichtungen übergeben werden können. An der "linken" Seite ist unterhalb der Sammel-Transporteinrichtung die Verpackungseinrichtung 50 schematisch dargestellt, bei welcher Arzneimittelportionen von den Sammeleinrichtungen 90 übergeben und verblistert werden.In this embodiment, the collective transport device is again provided with a transport means 190, on which a plurality of
