Abstract
Description
Die Erfindung betrifft eine Umfüllvorrichtung für Laborbehälter, welche es ermöglicht, eine pulverförmige Substanz rasch, sicher und ohne die Substanz zu verschütten, von einem ersten in einen zweiten Behälter umzufüllen. Dabei ist vor allem an Anwendungen im Zusammenhang mit Pulverdosiergeräten gedacht, welche einen Dosierkopf aufweisen, der von einem Arbeitsbehälter gespeist wird. Der Arbeitsbehälter kann als ein mit dem Dosierkopf verbindbarer oder mit diesem fest verbundener Behälter oder auch als ein Hohlraum im Innern des Dosierkopfes selbst ausgebildet sein.The invention relates to a refilling device for laboratory containers, which makes it possible to quickly, safely and without spilling the substance from a first to a second container to fill a powdery substance. It is especially intended for applications in the context of Pulverdosiergeräten, which have a dosing, which is fed by a working container. The working container can be designed as a container that can be connected to the dosing head or firmly connected to it, or as a hollow space in the interior of the dosing head itself.
Wenn der Substanzvorrat in dem Arbeitsbehälter aufgebraucht ist, so muss derselbe nachgefüllt werden, wobei Substanz aus einem Vorratsbehälter in den Arbeitsbehälter umgefüllt wird. Dieses Umfüllen von Substanz von einem ersten in einen zweiten Behälter ist in manchen Laboratorien ein relativ häufig auftretender Vorgang und kann durch einfaches Umschütten erfolgen, wenn das zu füllende Gefäss eine genügend grosse Öffnung besitzt und/oder ein versehentliches Verschütten von Substanz in Kauf genommen werden kann.If the substance supply is used up in the working container, it must be replenished, wherein substance is transferred from a reservoir into the working container. This transfer of substance from a first to a second container is a relatively common process in some laboratories and can be done by simply shaking when the vessel to be filled has a sufficiently large opening and / or accidental spillage of substance can be accepted ,
Wenn andrerseits der zu füllende Behälter nur eine kleine Öffnung besitzt, wenn die umzufüllende Substanz giftig ist oder wenn sonst aus irgend einem Grund jedes Verschütten auch von kleinsten Mengen vermieden werden muss, so wird das manuelle Umschütten oder auch das Umfüllen mithilfe von herkömmlichen Utensilien wie Einfülltrichtern und Spateln zu einer relativ zeitraubenden und zudem möglicherweise auch heiklen oder gefährlichen Tätigkeit.On the other hand, if the container to be filled has only a small opening, if the substance to be filled is poisonous, or if for any reason any spillage must be avoided even the smallest amounts, the manual Umpfütten or the transfer using conventional utensils such as funnels and spatulas to a relatively time-consuming and possibly also delicate or dangerous activity.
Eine weitere Schwierigkeit tritt zudem beim Umfüllen von Substanzen auf, welche mit der Umgebungsatmosphäre reagieren oder eine sehr hohe Bereitschaft zur Feuchtigkeitsaufnahme aufweisen. Dieses Problem könnte dadurch gelöst werden, dass man die Substanz in einer sogenannten Glovebox unter einer Schutzgasatmosphäre umfüllt, was jedoch umständlich und zeitraubend ist.Another difficulty also occurs when transferring substances that react with the ambient atmosphere or have a very high readiness for moisture absorption. This problem could be solved by filling the substance in a so-called glove box under a protective gas atmosphere, which is cumbersome and time consuming.
Kupplungsvorrichtungen mit Verschlussventilen sind seit langem im Stand der Technik bekannt. Sie werden insbesondere da eingesetzt, wo nach einem Umfüllvorgang verhindert werden soll, dass das umgefüllte Fluid aus den getrennten Kupplungsteilen austritt.Coupling devices with shut-off valves have long been known in the art. They are used in particular, where after a Umfüllvorgang should be prevented that the recirculated fluid exits the separate coupling parts.
Eine Kupplungsvorrichtung mit Verschlussventilen wird in der
Ferner sind im Stand der Technik viele Flaschenverschlüsse mit klappbarer Verschlusskappe bekannt und weit verbreitet. Ein solcher Flaschenverschluss wird beispielsweise in der
Die im Stand der Technik bekannten Flaschenverschlüsse sind gänzlich ungeeignet, die vorangehend erwähnten, giftigen Substanzen sicher umzufüllen, da sich zwischen der Mündung des Verschlusses und dem Arbeitsbehälter keine dichte Verbindung erreichen lässt, ohne die Verschlusskappe zuvor aufzuklappen und die Flaschenöffnung freizugeben.The bottle closures known in the prior art are wholly unsuitable for safely replenishing the aforementioned toxic substances, since no tight connection can be achieved between the mouth of the closure and the working container without first unfolding the cap and releasing the bottle opening.
Auch die Kupplungen mit Verschlussventilen in beiden Kupplungsteilen sind ungeeignet, da zwischen den beiden Ventilen ein Totvolumen vorhanden ist, in welchem Reste der transferierten Substanz hängen bleiben und in die Umwelt gelangen könnten, sobald die Kupplung aufgetrennt wird.Also, the couplings with shut-off valves in both coupling parts are unsuitable, since there is a dead volume between the two valves, in which remains of the transferred substance could get stuck and enter the environment as soon as the coupling is separated.
Die vorliegende Erfindung hat deshalb zur Aufgabe, eine Umfüllvorrichtung für Laborbehälter zu schaffen, welche es ermöglicht, eine insbesondere pulverförmige Substanz rasch und sicher von einem ersten in einen zweiten Behälter umzufüllen, wobei der Substanztransfer vom ersten in den zweiten Behälter im wesentlichen unter dichtem Verschluss erfolgt, so dass während des Transfervorganges und nach dem Transfervorgang keine Substanzpartikel nach aussen gelangen können, beziehungsweise möglichst keine Vermischung des in den Behältern vorhandenen gasförmigen Mediums mit der Umgebungsluft stattfinden kann.The present invention therefore has for its object to provide a container for refilling laboratory containers, which makes it possible to quickly and safely refill a particular powdered substance from a first to a second container, wherein the substance transfer from the first into the second container is substantially under tight closure so that no substance particles can escape to the outside during the transfer process and after the transfer process, or, if possible, no mixing of the gaseous medium present in the containers with the ambient air can take place.
Diese Aufgabe wird von einer Umfüllvorrichtung gemäss dem Anspruch 1 sowie von einer Transfermethode für pulverförmige Substanz gemäss dem Anspruch 12 erfüllt. Detailaspekte und weiterentwickelte Ausführungsformen der Erfindung sind in den weiteren untergeordneten Ansprüchen definiert.This object is achieved by a transfer device according to
Eine Umfüllvorrichtung gemäss der vorliegenden Erfindung umfasst ein Gehäuse, welches entweder fest oder durch ein Kupplungsmittel, mit einem Vorratsbehälter verbunden ist. Das Kupplungsmittel kann beispielsweise eine Gewindeverbindung, eine Schnappverbindung aber auch eine einfache Steckverbindung sein. Das Gehäuse der Umfüllvorrichtung hat eine Durchtrittsöffnung sowie ein mit dem Gehäuse beweglich verbundenes Verschlussteil zum Verschliessen der Durchtrittsöffnung. Das Verschlussteil hat mindestens eine Anschlussstelle für mindestens einen Arbeitsbehälter und ist relativ zum Gehäuse zwischen mindestens einer offenen Stellung und mindestens einer geschlossenen Stellung drehbar oder schiebbar. In der geschlossenen Stellung ist die Durchtrittsöffnung durch das Verschlussteil verschlossen, und in der offenen Stellung ist der Innenraum des Vorratsbehälters über die Durchtrittsöffnung mit dem Innenraum des in der mindestens einen Anschlussstelle eingesetzten Arbeitsbehälters verbunden.A transfer device according to the present invention comprises a housing, which is either fixed or connected by a coupling means, with a reservoir. The coupling means may for example be a threaded connection, a snap connection but also a simple plug connection. The housing of the transfer device has a passage opening and a closure member movably connected to the housing for closing the passage opening. The closure member has at least one connection point for at least one working container and is rotatable or slidable relative to the housing between at least one open position and at least one closed position. In the closed position, the passage opening is closed by the closure part, and in the open position, the interior of the reservoir is connected via the passage opening with the interior of the working container used in the at least one connection point.
Die erfindungsgemässe Umfüllvorrichtung eignet sich zum Verbinden von Behältern, um insbesondere eine pulverförmige Substanz von einem ersten, im folgenden als Vorratsbehälter bezeichneten Behälter in einen zweiten, im folgenden als Arbeitsbehälter bezeichneten Behälter umzufüllen. Weil der Arbeitsbehälter direkt mit dem Verschlussteil verbindbar ist, kann die Öffnung des Arbeitsbehälters unmittelbar an der Durchtrittsöffnung vorbeigeführt werden. Dadurch sind keine, ein Totvolumen bildende, auftrennbare Verbindungsschächte notwendig, bei deren Auftrennung die Gefahr besteht, dass Substanz in die Umgebung gelangen kann.The transfer device according to the invention is suitable for connecting containers in order, in particular, to transfer a powdery substance from a first container, hereinafter referred to as a reservoir, into a second container, hereinafter referred to as a working container. Because the working container can be connected directly to the closure part, the opening of the working container can be guided past the passage opening directly. As a result, no, a dead volume forming, separable connection shafts are necessary, the separation of which there is a risk that substance can enter the environment.
Die erfindungsgemässe Umfüllvorrichtung ermöglicht, dass eine vor dem Substanztransfer verschlossene Vorratsbehältermündung geöffnet und auch wieder geschlossen werden kann, während die Behältermündungen zusammengekuppelt sind. Damit gestaltet sich der Umfüllvorgang beispielsweise so, dass der zu füllende Arbeitsbehälter mit einem durch die Umfüllvorrichtung verschlossenen Vorratsbehälter gekoppelt wird, welcher mit seiner Mündung nach unten in einer Halterung angeordnet ist. Dann wird durch Verschieben oder Verschwenken des Verschlussteils die Durchtrittsöffnung geöffnet, so dass Substanz aus dem Vorratsbehälter in den zu füllenden Arbeitsbehälter fliessen kann. Durch diese Anordnung kann die Substanz vom Vorratsbehälter in den Arbeitsbehälter gelangen, gleichzeitig wird durch die einfliessende Substanz das im Arbeitsbehälter vorhandene Gasvolumen verdrängt und strömt infolge des durch die ausfliessende Substanz erzeugten Unterdrucks im Vorratsbehälter in den Vorratsbehälter. Jegliche Staubentwicklung ausserhalb der erfindungsgemässen Umfüllvorrichtung wird somit vermieden. Anschliessend wird das Verschlussteil wieder verschlossen und der Arbeitsbehälter wird aus der Anschlussstelle gelöst und verschlossen.The transfer device according to the invention makes it possible for a reservoir mouth which is closed before the substance transfer to be opened and also closed again while the container mouths are coupled together are. Thus, the Umfüllvorgang designed, for example, so that the working container to be filled is coupled with a closed by the Umfüllvorrichtung reservoir, which is arranged with its mouth down in a holder. Then, the passage opening is opened by moving or pivoting the closure part, so that substance from the reservoir can flow into the working container to be filled. By this arrangement, the substance can pass from the reservoir into the working container, at the same time the gas volume present in the working container is displaced by the inflowing substance and flows as a result of the generated by the effluent substance negative pressure in the reservoir into the reservoir. Any dust development outside the inventive transfer device is thus avoided. Subsequently, the closure part is closed again and the working container is released from the connection point and closed.
Die durch die Erfindung geschaffene Möglichkeit, einen Vorratsbehälter verschlossen zu halten, solange die Behältermündungen nicht zusammengekuppelt sind, hat ausserdem den Vorteil, dass der Inhalt eines so verschlossenen Vorratsbehälters von jedem auch nur kurzzeitigen Kontakt mit der Umgebungsatmosphäre abgeschlossen ist, wodurch beispielsweise eine Feuchtigkeitsaufnahme oder oxydation der in dem Behälter enthaltenen Substanz verhindert werden kann.The possibility provided by the invention to keep a reservoir closed, as long as the container mouths are not coupled, also has the advantage that the contents of such a closed reservoir of each even short-term contact with the ambient atmosphere is completed, creating, for example, a moisture absorption or oxidation the substance contained in the container can be prevented.
Die erfindungsgemässe Umfüllvorrichtung kann so gestaltet sein, dass das Verschlussteil durch Betätigung von Aussen, beispielsweise von einer Bedienungsperson, geöffnet und verschlossen wird. In einer vorteilhaften Ausführungsform besteht mindestens der zu füllende Arbeitsbehälter aus einem durchsichtigen Material, so dass die Bedienungsperson den Materialtransfer beobachten und durch Verstellen des Verschlussteils steuern kann.The inventive refilling device can be designed so that the closure part is opened and closed by actuation of the outside, for example by an operator. In an advantageous embodiment, at least the working container to be filled consists of a transparent material, so that the operator can observe the material transfer and control it by adjusting the closure part.
Sofern das Spiel zwischen dem Verschlussteil und dem Gehäuse kleiner ist als die kleinste Partikelgrösse, kann keine Substanz durch diesen Spalt unkontrolliert in die Umgebung gelangen.If the clearance between the closure part and the housing is smaller than the smallest particle size, no substance can pass uncontrollably through this gap into the environment.
Sinnvollerweise wird aber an der Mündung der Durchtrittsöffnung mindestens ein Dichtungsring koaxial zur Durchtrittsöffnung angeordnet, welcher in stetigem Kontakt mit dem Verschlussteil ist. Mittels dieses Dichtungsrings werden beim Verschieben oder Verschwenken des Verschlussteils Reste der Substanz von der Mündung des Arbeitsbehälters abgestreift und in der Durchtrittsöffnung zurückgehalten und/oder in den Arbeitsbehälter befördert. Die Form des Dichtungsrings und dessen Querschnitt kann beliebig gewählt werden und muss nicht zwingend kreisförmig ausgestaltet sein.It makes sense, however, arranged at the mouth of the passage opening at least one sealing ring coaxial with the passage opening, which is in constant contact with the closure part. By means of this sealing ring residues of the substance are stripped off the mouth of the working container during the displacement or pivoting of the closure part and retained in the passage opening and / or transported into the working container. The shape of the sealing ring and its cross section can be chosen arbitrarily and does not necessarily have to be circular.
Um die Sicherheit zu erhöhen, können zwischen dem Verschlussteil und dem Gehäuse weitere Dichtungselemente, beispielsweise ein Faltenbalg angeordnet sein.In order to increase safety, further sealing elements, for example a bellows, can be arranged between the closure part and the housing.
Erfindungsgemäss sind Möglichkeiten einer zwangsläufigen Verriegelung zum Sichern der Verbindungen der Umfüllvorrichtung mit dem Vorratsbehälter und dem Arbeitsbehälter vorgesehen. Zum Beispiel kann mit einer Anschlussstellenverriegelung die Verbindung des in der mindestens einen Anschlussstelle eingesetzten Arbeitsbehälters unlösbar gesichert werden, wenn das Verschlussteil in der offenen Stellung ist. Des Weiteren kann das Verschlussteil mit einer Verschlussteilverriegelung in der geschlossenen Stellung blockiert werden, wenn kein Arbeitsbehälter mit der mindestens einen Anschlussstelle verbunden ist.According to the invention possibilities of positive locking for securing the connections of the transfer device are provided with the reservoir and the working container. For example, with a terminal interlock, the connection of the working container inserted in the at least one connection point can be secured inextricably when the closure part is in the open position. Furthermore, the closure member may be locked with a closure member lock in the closed position when no working container is connected to the at least one connection point.
Diese Zwangsläufigkeit zwischen dem Vorhandensein eines Arbeitsbehälters in der Anschlussstelle und der Freigabe des Verschlussteils kann besonders vorteilhaft dadurch erreicht werden, dass mit dem Einsetzen eines Arbeitsbehälters in die Anschlussstelle die Verschlussteilverriegelung betätigt und das Verschlussteil entriegelt wird und durch das Herausnehmen des Arbeitsbehälters aus der Anschlussstelle das Verschlussteil automatisch wieder verriegelt wird.This inevitability between the presence of a working container in the connection point and the release of the closure part can be achieved particularly advantageous in that with the onset of a working container in the connection point, the closure part locking is actuated and the closure part is unlocked and by removing the working container from the connection point the closure part is automatically locked again.
Eine Ausführungsform der erfindungsgemässen Umfüllvorrichtung mit mehreren am Verschlussteil ausgebildeten Anschlussstellen eignet sich für Anwendungen, wo mehrere Arbeitsbehälter mit der gleichen Substanz aus einem Vorratsbehälter zu füllen sind. Für den Fall, dass dabei nicht alle vorhandenen Anschlussstellen mit zu füllenden Arbeitsbehältern besetzt sind, wird vorgesehen, dass der Drehwinkel oder die Verschiebestrecke des Verschlussteils durch die Verschlussteilverriegelung nur soweit freigebbar ist, wie Anschlussstellen lückenlos hintereinander mit Arbeitsbehältern bestückt sind, womit das Ausfliessen von Substanz durch unbesetzte Anschlussstellen verhindert wird.An embodiment of the transfer device according to the invention with a plurality of connection points formed on the closure part is suitable for applications where a plurality of working containers with the same substance are to be filled from a storage container. In the event that not all existing connection points are filled with working containers to be filled, it is provided that the angle of rotation or the displacement distance of the closure part can only be released by the closure part locking to the extent that connection points are equipped with working containers without any gaps, thus preventing the escape of substance through unoccupied connection points.
Falls das Gehäuse der Umfüllvorrichtung nicht unlösbar, sondern durch ein Kupplungsmittel mit dem Vorratsbehälter verbunden ist, kann eine Kupplungsmittelverriegelung vorgesehen sein, um ein unbeabsichtigtes Öffnen des Vorratsbehälters zu vermeiden.If the housing of the transfer device is not insoluble, but is connected by a coupling means with the reservoir, a coupling agent locking may be provided to prevent accidental opening of the reservoir.
Das Kupplungsmittel zur Verbindung der Umfüllvorrichtung mit einem Vorratsbehälter und auch die Anschlussstelle zur Verbindung mit einem Arbeitsbehälter können beispielsweise als Schraubverbindung, Bajonettverschlussverbindung, Einrastvorrichtung oder Einschubvorrichtung gestaltet sein. Vorzugsweise lassen sich das Kupplungsmittel und die Anschlussstelle verwechslungsfrei voneinander unterscheiden, so dass das Kupplungsmittel nur mit einem Vorratsbehälter und die Anschlussstelle nur mit einem Arbeitsbehälter verbunden werden können.The coupling means for connecting the transfer device with a storage container and also the connection point for connection to a working container can be designed, for example, as a screw connection, bayonet connection, latching device or insertion device. Preferably, the coupling agent and the connection point can be distinguished from one another without being confused, so that the coupling agent can only be connected to a storage container and the connection point can only be connected to a working container.
Ferner ist es vorteilhaft, wenn die Umfüllvorrichtung und die mit ihr zu verbindenden Vorratsbehälter und Arbeitsbehälter in der Weise standardisiert sind, dass Vorratsbehälter direkt mit dem Kupplungsmittel und Arbeitsbehälter direkt mit der Anschlussstelle verbunden werden können. Für Vorrats- und Arbeitsbehälter, welche diesem Verbindungsstandard nicht entsprechen, können zweckmässige Adapter geschaffen werden. Um wie weiter oben beschrieben, die Bildung von Totvolumen zu vermeiden, verbleiben diese Adapter vorzugsweise an den Behältern und nicht an der Umfüllvorrichtung. Dadurch werden die unterschiedlichen Behälter mit einer standardisierten Schnittstelle versehen, durch welche sich diese unterschiedlichen Behälter auch auf einfache Weise mit einem Gerät mit derselben standardisierten Schnittstelle, beispielsweise einer Dosiervorrichtung verbinden lassen.Furthermore, it is advantageous if the transfer device and the storage container and working container to be connected to it are standardized in such a way that storage containers can be connected directly to the coupling means and working container directly to the connection point. For storage and working containers that do not meet this standard connection, appropriate adapter can be created. In order to avoid the formation of dead volumes, as described above, these adapters preferably remain on the containers and not on the transfer device. As a result, the different containers are provided with a standardized interface, by means of which these different containers can also be easily connected to a device with the same standardized interface, for example a dosing device.
Im Gehäuse der Umfüllvorrichtung kann auch eine nachfüllbare Kammer für ein Trocknungsmittel oder eine Verbindungsstelle zu einer auswechselbaren Trocknungsmittelpatrone ausgebildet sein, wobei das Trocknungsmittel atmosphärisch mit dem Innenraum des Vorratsbehälters kommuniziert und gegebenenfalls Feuchtigkeit aus der im Vorratsbehälter befindlichen Substanz absorbiert.In the housing of the transfer device, a refillable chamber for a drying agent or a connection point to a replaceable desiccant cartridge can be formed, wherein the desiccant atmospherically communicates with the interior of the reservoir and optionally absorbs moisture from the substance in the reservoir.
Ferner kann am Gehäuse der Umfüllvorrichtung mindestens ein Gasanschluss angeordnet sein, durch welchen beispielsweise ein Schutzgas zugeführt werden kann. Gegebenenfalls kann dadurch auch ein im Vorratsbehälter oder Arbeitsbehälter vorhandenes, gasförmiges Medium ersetzt werden. Dies kann verschiedene Vorteile haben. Beispielsweise kann durch die Zuführung eines entsprechenden Gases die Fliessfähigkeit der Substanz verändert oder gar die Reaktionsfähigkeit der Substanz beeinflusst werden. Selbstverständlich ist auch die Anordnung mehrerer Gasanschlüsse möglich, welche mit einzelnen Bereichen der vorliegenden Umfüllvorrichtung und/oder mit dem Vorratsbehälter und/oder mit dem Arbeitsbehälter verbunden sind.Furthermore, at least one gas connection can be arranged on the housing of the transfer device, through which, for example, a protective gas can be supplied. Optionally, this can also be replaced by a gaseous medium present in the storage container or working container. This can have several advantages. For example, can be changed by the supply of a corresponding gas, the flowability of the substance or even the reactivity of the substance can be influenced. Of course, the arrangement of multiple gas connections is possible, which are connected to individual areas of the present transfer device and / or with the reservoir and / or with the working container.
Nach dem Füllen kann der Arbeitsbehälter beispielsweise von Hand mit einem zum Behälter gehörenden Deckel verschlossen werden. Es kann aber auch vorgesehen sein, dass am Gehäuse der Umfüllvorrichtung eine Verschlusssiegelvorrichtung und/oder eine Verschlussvorrichtung angeordnet ist, welche zum Aufbringen eines Deckels , Verschlussstopfens und/oder eines Versiegelungsklebers auf der Einfüllöffnung des Arbeitsbehälters dient, wenn derselbe nach erfolgter Befüllung von der Anschlussstelle gelöst wird.After filling the work container can be closed, for example, by hand with a lid belonging to the container. However, it can also be provided that a closure sealing device and / or a closure device is arranged on the housing of Umfüllvorrichtung, which serves for applying a lid, sealing plug and / or a sealing adhesive on the filling opening of the working container when the same solved after filling of the connection point becomes.
Damit beim Umfüllvorgang eine möglichst dichte Verbindung zwischen dem Vorratsbehälter und dem Arbeitsbehälter entsteht, kann die mindestens eine Anschlussstelle ein Federelement aufweisen, mittels welchem Federelement ein in die Anschlussstelle eingesetzter Arbeitsbehälter gegen das Gehäuse spannbar ist.So that during the transfer process the most dense connection possible between the storage container and the working container, the at least one connection point can have a spring element, by means of which spring element a working container inserted into the connection point can be tensioned against the housing.
Ein Verfahren für das Umfüllen einer Substanz von einem Vorratsbehälter in einen Arbeitsbehälter, die durch die erfindungsgemässe Umfüllvorrichtung miteinander verbunden sind, umfasst im wesentlichen die folgenden Schritte:
- ein Vorratsbehälter wird mit dem Kupplungsmittel einer Umfüllvorrichtung verbunden. Dabei wird beispielsweise ein Schraubdeckel des Vorratsbehälters abgeschraubt und durch die Umfüllvorrichtung ersetzt, wobei sich das Verschlussteil im geschlossenen Zustand befindet,
- mindestens ein Arbeitsbehälter wird mit dem Verschlussteil durch die mindestens eine Anschlussstelle verbunden,
- gegebenenfalls wird vor dem Öffnen der Durchtrittsöffnung der Arbeitsbehälter durch das Verschieben oder Verschwenken des Verschlussteils mit einer Trockenmittelkammer verbunden,
- gegebenenfalls wird über einen Schutzgasanschluss das im Vorratsbehälter und/oder im Arbeitsbehälter vorhandene gasförmige Medium durch ein inertes Schutzgas ersetzt,
- die Durchtrittsöffnung wird durch das Verschieben oder Verschwenken des Verschlussteils geöffnet und die mit der Umfüllvorrichtung verbundenen Behälter in eine Umfülllage gebracht, so dass Substanz infolge der Schwerkraft vom Vorratsbehälter in den Arbeitsbehälter fliesst,
- nachdem der Arbeitsbehälter gefüllt ist, wird das Verschlussteil wieder geschlossen und
- der Arbeitsbehälter mittels einer Verschlusssiegelvorrichtung versiegelt und/oder der Arbeitsbehälter aus der Anschlussstelle gelöst.
- a reservoir is connected to the coupling means of a transfer device. In this case, for example, a screw of the Unscrewed and replaced by the transfer device, wherein the closure member is in the closed state,
- at least one working container is connected to the closure part by the at least one connection point,
- if appropriate, the working container is connected to a desiccant chamber by the displacement or pivoting of the closure part before the passage opening is opened,
- if appropriate, the gaseous medium present in the storage container and / or in the working container is replaced by an inert gas via an inert gas connection by an inert protective gas,
- the passage opening is opened by the displacement or pivoting of the closure part, and the containers connected to the transfer device are brought into a transfer position, so that substance flows from the storage container into the work container as a result of gravity,
- after the working container is filled, the closure part is closed again and
- the working container is sealed by means of a closure sealing device and / or the working container is released from the connection point.

In der andern Anschlagsstellung ist die Anschlussstelle 5 und damit die Mündung des Arbeitsbehälters 6 zur Durchtrittsöffnung 10 versetzt, so dass die Durchtrittsöffnung 10 durch das Verschlussteil 7 verschlossen wird. Die Gestaltung des Verschlussteils 7 als manuell beweglicher Schieber ist besonders vorteilhaft in Verbindung mit einem Arbeitsbehälter 6, der aus durchsichtigem Material hergestellt ist, da die fortschreitende Füllung des Arbeitsbehälters 6 beobachtet und durch Bewegen des Verschlussteils 7 gesteuert und gestoppt werden kann. Damit keine Substanzpartikel in die Umgebung gelangen können, weist die Umfüllvorrichtung 1 zwei Dichtungssysteme auf. Das erste Dichtungssystem ist ein koaxial zur Durchtrittsöffnung 10 angeordneter, ringförmig ausgebildeter Dichtungsring 9. Dieser Dichtungsring 9 dichtet einerseits das der besseren Erkennbarkeit wegen in der

Die Anschlussstelle 39 für den Arbeitsbehälter 36 ist als Bajonettverbindung ausgebildet, welche mit dem drehbaren Verschlussteil 37 zwangsläufig so zusammenarbeitet, so dass die im Gehäuse 32 ausgebildete Durchtrittsöffnung 30 verschlossen ist, wenn kein Arbeitsbehälter 36 in der Anschlussstelle eingesetzt ist. Diese Zwangsläufigkeit wird mittels mindestens einer im Verschlussteil 37 ausgebildeten Verschlussteilnute 45 und mittels mindestens einer im Gehäuse 32 L-förmig ausgebildeten Steuernute 46 erreicht. Damit ein Arbeitsbehälter 36 in die Anschlussstelle 39 eingesetzt werden kann, muss der Nocken 38 gleichzeitig in die Verschlussteilnute 45 und in die Steuernute 46 eingreifen können. Durch die Führung des Nockens 38 in der L-förmig ausgebildeten Steuernute 46, kann der Arbeitsbehälter 36 während des Umfüllvorganges auch nicht aus der Anschlussstelle 39 herausgezogen werden, solange die Durchtrittsöffnung 30 nicht verschlossen ist.The
Um zu verhindern, dass an den Seitenwänden des Durchbruchs 42 Substanz anhaftet, ist an der Mündung des Arbeitsbehälters 36 ein Arbeitsbehälteradapter 49 angeordnet. Dessen Durchlass greift bei in das Verschlussteil 37 eingesetztem Arbeitsbehälter 36 in den Durchbruch 42 ein, so dass nur der Arbeitsbehälteradapter 49 und nicht der Durchbruch 42 mit Substanz in Berührung kommt. Nach dem Befüllen des Arbeitsbehälters 36 kann der Durchlass beispielsweise mit einer Schutzkappe dicht verschlossen werden. Gegebenenfalls kann der Arbeitsbehälteradapter 49 auch entfernt und durch einen Verschlussstopfen ersetzt werden.In order to prevent
Ein spontanes Drehen des Verschlussteils 37 kann durch die Kontaktreibung mit dem Gehäuse 32 verhindert werden, oder das Verschlussteil 37 kann durch eine nicht dargestellte Drehfeder in die geschlossene Stellung gedrängt werden, in welcher der Durchbruch 42 zur Durchtrittsöffnung 30 um 180º versetzt ist.A spontaneous rotation of the
Durch vollständiges Einstecken des Halses 48 in die Anschlussstelle 39 und durch anschliessendes Drehen um 180°wird somit einerseits der Hals 48 in der Anschlussstelle 39 beziehungsweise im Gehäuse 32 fixiert und andererseits das Verschlussteil 37 gleichzeitig in die geöffnete Stellung gedreht, so dass der Weg vom Vorratsbehälter 33 in den Arbeitsbehälter 36 durch die Durchtrittsöffnung 30 und den Durchbruch 42 freiliegt und die Substanz infolge der Schwerkraft vom Vorratsbehälter 33 in den Arbeitsbehälter 36 fliessen kann. Der gefüllte Arbeitsbehälter 36 wird durch Drehen und Ausziehen wieder von der Anschlussstelle 39 entkoppelt, wobei das Verschlussteil 37 von der Drehung mitgenommen wird und somit den Durchgang 30 wieder verschliesst.By completely inserting the
Eine erfindungsgemässe Umfüllvorrichtung kann auch mit mehr als einer Anschlussstelle für Arbeitsbehälter versehen sein.
Selbstverständlich sind auch Ausgestaltungen von Umfüllvorrichtungen möglich, bei welcher mehrere Arbeitsbehälter parallel befüllt werden können. Zu diesem Zwecke müssen aber pro parallel zu befüllendem Behälter dementsprechend viele Durchtrittsöffnungen im Gehäuse ausgebildet sein.Of course, embodiments of Umfüllvorrichtungen are possible in which a plurality of working containers can be filled in parallel. For this purpose, however, correspondingly many through openings must be formed in the housing per container to be filled in parallel.
