Description

Es sind Container-Mischer bekannt, die speziell für ein produktschonendes Mischen und ein flexibles Aufnehmen von verschiedenen Mischbehältern konzipiert sind, beispielsweise im Pharmabereich. Ein hydraulisches Spannsystem gewährleistet eine Aufnahme der Mischbehälter. Ein SPS- und rezeptgesteuerter Mischvorgang ermöglicht eine Anpassung an das Mischgut. Die Aufnahme von unterschiedlichen Behältergrößen oder Adapter für Fässer und Kleinbehälter lassen sich durch ein Spannbalkensystem realisieren. Als Handlingsfunktionen sind Heben, Senken, Drehen, Schwenken einer Mischersäule erforderlich. Nutzer erwarten ein automatisches Beschicken und Entladen von solcher Mischtechnik. Ein Zerhacker soll im Mischbehälter einsetzbar sein. Ein Sprühsystem zum Aufbringen von Flüssigkeiten auf das Mischgut, vor- und nachgeschaltete Wägetechnik, eine dosierte Entleerung, ein NIR-System, usw. sind einzusetzen. Die Anforderung heißt insgesamt: reproduzierbares Mischen im geschlossenen System.Container mixers are known which are specially designed for gentle mixing of products and for flexibly accommodating various mixing containers, for example in the pharmaceutical sector. A hydraulic tensioning system ensures that the mixing containers are picked up. A PLC and recipe-controlled mixing process allows adaptation to the mix. The inclusion of different container sizes or adapters for drums and small containers can be realized by a tension bar system. As handling functions lifting, lowering, turning, pivoting of a mixer column are required. Users expect an automatic loading and unloading of such mixing technology. A chopper should be usable in the mixing container. A spraying system for applying liquids to the mix, upstream and downstream weighing, a metered drain, an NIR system, etc. should be used. Overall, the requirement is: reproducible mixing in a closed system.

Dazu bestehen bekannte Mischbehälter beispielsweise aus Edelstahl. Es gibt unterschiedliche Mischcontainer im Grundmaß und der Höhe, freistehende oder Boden-Decken-gelagerte Ausführungen. Die Beladung des Mischbehälters kann nach dem Stand der Technik mittels Trolley, Handhubwagen bis hin zur vollautomatischen Rollenbahnbeschickung und Entladung geschehen. Unterschiedliche Behälterspannsysteme von manueller bis hin zur vollautomatischen Ausführung dienen dann zum sicheren Einspannen der Mischcontainer in die bekannte Mischvorrichtung. Eine Sicherheitsumhausung ist in Abhängigkeit zum Aufstellort und Prozessablauf vorgesehen. Eine standardmäßige Schrägausrichtung zur Mischachse soll nach dem Einspannen erreicht sein.For this purpose, known mixing containers, for example made of stainless steel. There are different mixing containers in basic size and height, freestanding or floor-ceiling mounted versions. The loading of the mixing container can be done according to the prior art by means of trolley, hand pallet truck to fully automatic roller conveyor loading and unloading. Different container clamping systems from manual to fully automatic design are then used for secure clamping of the mixing container in the known mixing device. A security enclosure is dependent on the installation site and Process flow provided. A standard oblique orientation to the mixing axis should be achieved after clamping.

In einem Kopfraum des Containers sollen sich keine Einbauten befinden. Eine Integration von vor- bzw. nachgeschalteten Prozessen sowie Handlingsfunktionen ( Heben, Kippen, Schwenken, Absetzen, Andocken usw. ) sind erforderlich, ebenso eine hohe Verfügbarkeit, da die Reinigung des bekannten Mischbehälters außerhalb des Mischers erfolgt. Oft ist eine explosionsgeschützte Ausführung gefordert.In a headspace of the container should be no internals. An integration of upstream and downstream processes and handling functions (lifting, tilting, pivoting, settling, docking, etc.) are required, as well as high availability, since the cleaning of the known mixing container takes place outside of the mixer. Often an explosion-proof design is required.

Die reproduzierbar zu mischenden Materialien werden oft in flexiblen Gebinden angedient, um dann in Mischbehälter umgefüllt zu werden. Mischbehälter müssen bisher nach dem Mischen in weitere Gebinde entleert werden, danach gereinigt. Es ist Aufgabe der Erfindung diese Prozesse zu vereinfachen, ohne die Reproduzierbarkeit zu gefährden.The reproducible materials to be mixed are often tendered in flexible containers to be then transferred to mixing vessels. Mixing containers must be emptied into other containers after mixing, then cleaned. It is an object of the invention to simplify these processes without jeopardizing the reproducibility.

Dazu wird vorgeschlagen, ein Mischen in einem "Single-use bag" zu ermöglichen, wobei das vergleichbar mit oben beschriebenen bekannten Kleinchargenmischern geschehen soll. Das flexible Gebinde, in dem das Material zum Mischen angeliefert ist, sollte zum Einstieg in den Erfindungsgedanken schon gewisse Voraussetzungen mitbringen. Es sollte nämlich in ein Gestell einspannbar sein, derart, dass zumindest Abschnitte der flexiblen Gebindewände eine definierte Form annehmen, die der Mischbehälter vor Beginn des Mischens angenommen haben soll, um reproduzierbar mischen zu können.For this purpose, it is proposed to enable mixing in a "single-use bag", which is to be done in a manner comparable to the known small-batch mixers described above. The flexible container, in which the material is supplied for mixing, should already bring certain prerequisites to get into the inventive concept. It should namely be clamped in a frame, such that at least portions of the flexible container walls assume a defined shape, which should have assumed the mixing container before the start of mixing in order to mix reproducibly.

Die Idee ist es also, einen ein flexibles Gebinde, das beispielsweise schon Lager- und Transportgebinde ist, selbst als Mischbehälter zu verwenden, es zum Mischen in einem Gestell zu spannen, so dass zumindest beinahe feste Wände und Böden entstehen und das Mischen in diesem nun zumindest nicht mehr vollständig flexiblen Gebinde ein reproduzierbaren Prozess darstellt. Dieser Mischprozess in festen Containern, ist nämlich schon mehrfach validiert und diese Prozesssicherheit bleibt als Ergebnis erhalten, wenn erfindungsgemäß nicht mehr in einen Mischbehälter umgefüllt werden muss, sondern der flexible Transportbehälter selbst zum Mischbehälter wird.The idea is therefore to use a flexible container, which is for example already storage and transport containers, even as a mixing container to stretch it for mixing in a rack, so that at least almost solid walls and floors arise and mixing in this now at least not completely flexible container represents a reproducible process. This mixing process in solid containers, namely, has already been validated several times and this process reliability remains as a result, if according to the invention no longer needs to be transferred to a mixing vessel, but the flexible transport container itself is the mixing container.

Der Vorteil liegt auf der Hand: nie mehr Transportbehälter oder Mischcontainer waschen, keine Containerwaschmaschinen mehr usw.The advantage is obvious: never wash more transport containers or mixing containers, no more container washing machines, etc.

Die Erfindung schlägt dazu beispielsweise ein Gestell mit vier gleichen Seitenteilen aus einem Edelstahlblech vor. Beim Konfektionieren wird das bevorzugt ausgestaltete flexible Gebinde, das seitlich vier Taschen hat, von oben in das Gestell montiert und im unteren Bereich fest gespannt. Damit ist für den Mischprozess für ähnliche Verhältnisse wie bei dem bekannten Edelstahlcontainer als Mischbehälter gesorgt.For example, the invention proposes a frame with four identical side parts made of a stainless steel sheet. During assembly, the preferably configured flexible container, which has four pockets on the side, mounted from above into the frame and clamped in the lower area. This provides for the mixing process for similar conditions as in the known stainless steel container as a mixing container.

Ein erfindungsgemäßes Verfahren, insbesondere zum Mischen eines Schüttgutes in einem flexiblen Gebinde nutzt ein erfindungsgemäßes flexibles Gebinde und Gestell vorteilhaft, um insgesamt beispielsweise Kosten und Aufwand zu sparen, ohne auf Anforderungen an Reproduzierbarkeit zu verzichten.A method according to the invention, in particular for mixing a bulk material in a flexible container, makes advantageous use of a flexible container and frame according to the invention in order, for example, to save costs and effort overall, without renouncing demands on reproducibility.

Eine vorteilhafte Ausführungsform eines Gestells zur Aufnahme des Singe-Use Gebindes weist grob dreieckförmige Seitenwandelemente auf, die um eine untere Basis drehbar im Gestell gelagert sind. Das obere freie Ende des jeweiligen Seitenwandelements ist zur Aufnahme eines oberen Endes des Gebindes kongruent ausgeformt. Besonders bevorzugt lassen sich vier obere freie Enden als ein Ring um einen Flansch verbinden, was gleichzeitig ein "Gestraffthalten" von Gebindewandungen mittels der als Spannflächen ausgebildeten Seitenwandelemente bewirkt.An advantageous embodiment of a frame for receiving the sing-use container has roughly triangular side wall elements which are mounted rotatably about a lower base in the frame. The upper free end of the respective side wall member is congruent for receiving an upper end of the container. More preferably, four upper free ends can be connected as a ring around a flange, which at the same time causes a "tightening" of container walls by means of the side wall elements designed as clamping surfaces.

Nachfolgend wird die Erfindung anhand von einem in Figuren dargestellten Ausführungsbeispiel näher beschrieben. Es zeigen

  • Fig. 1 eine perspektivische Darstellung eines flexiblen Gebindes, bereitstehend oberhalb eines Gestells mit geöffneten Spannflächen zum Aufspannen des flexiblen Gebindes, wobei das Gestell oberhalb eines Fahrwagens dargestellt ist,

  • Fig. 5A +B zwei 90° zueinander gedrehte Seitenansichten auf ein weiteres Beispiel eines flexiblen Gebindes und

The invention will be described in more detail with reference to an embodiment shown in FIGS. Show it
  • Fig. 1 a perspective view of a flexible container, standing above a frame with open clamping surfaces for clamping the flexible container, the frame is shown above a trolley,
  • Fig. 2 the rack with trolley FIG. 1 with clamping surfaces closed around the flexible container,

  • Fig. 5A + B two 90 ° to each other rotated side views of another example of a flexible container and

Ein erfindungsgemäßes Ausführungsbeispiel eines Gestells 10 ist in den Figuren 1 bis 3 dargestellt. Das flexible Gebinde ist in zwei Ausführungsvarianten aber jeweils eine Variante in allen Figuren dargestellt, in den Figuren 4 bis 6 separat ohne Gestell.An inventive embodiment of a frame 10 is in the FIGS. 1 to 3 shown. The flexible container is in two variants but each a variant in all figures shown in the FIGS. 4 to 6 separately without frame.

Der Erfindung liegt die Idee zugrunde, ein solches flexibles Gebindes 20 als Mischbehälter eines validierten Mischverfahrens zu verwenden. Da das flexible Gebinde 20 nicht aus sich alleine und auch nicht nach Befüllen in dieser rigiden Form bereitstehen kann, schlägt die Erfindung vor, an dem flexiblen Gebinde Angriffsstellen oder -flächen derart auszugestalten, dass man es zumindest teilflächig aufspannen kann. Insofern führen die Darstellungen in die Irre, weil man beim Betrachten den Eindruck haben könnte, das Gebinde steht in dieser Form ohne Hilfe. Das ist nicht so.The invention is based on the idea of using such a flexible container 20 as a mixing container of a validated mixing method. Since the flexible container 20 can not be prepared by itself and not after filling in this rigid form, the invention proposes to design on the flexible container attack points or surfaces such that it can span it at least part of the area. In this respect, the representations are misleading, because one could have the impression when viewing that the container stands in this form without help. It's not like this.

Das flexible Gebinde 20 wird erfindungsgemäß dazu in ein Gestell 10 eingespannt.The flexible container 20 is clamped according to the invention in a frame 10.

Zumindest Wandbereiche, bevorzugt aber seitlich umlaufend die vollständige Wandung und der Boden 24, werden derart aufgespannt, dass gemäß den Darstellungen ebene Wandflächen von dem flexiblen Gebinde 20 angenommen sind. Dazu können am Boden, vgl. Figur 8, diverse Laschen angeordnet sein, in Figur 8 zur besseren Übersicht nur eine einzige. Es sind bevorzugt an den unteren Seitenkanten Laschen herabhängend befestigt, die beispielsweise mittig ein Loch aufweisen. Man könnte diese herabhängend dargestellten Laschen mithin in Streben des Gestells einhängen, nicht dargestellt.At least wall areas, but preferably laterally encircling the entire wall and the bottom 24, are clamped in such a way that, according to the illustrations, flat wall surfaces of the flexible container 20 are assumed. These can be done on the ground, cf. Figure 8, various tabs may be arranged in Figure 8 for clarity only a single. It is preferred attached to the lower side edges tabs hanging down, for example, have a hole in the center. One could hang these hanging tabs thus shown in struts of the frame, not shown.

Außer diesen in Gebindeinnere hinein materialundurchlässigen Anschlüssen zum Aufspannen von zumindest Wandbereichen entsprechend einer definierten Form weist das Gebinde 20 zumindest einen Andockanschluss zum Befüllen und Entleeren auf. Dazu ist ein Kupplungselement 22 dargestellt, das in einer einfachen Form schlicht ein Ring sein kann. Es kann aber auch nicht nur oben sondern auch unten eine solche Öffnung vorgesehen sein. Man muss das Gebinde zum Erreichen seiner gewollten Form ggf. dosiert belüften können. Dazu weist das Gebinde bevorzugt eine Ventilöffnung oder einen Druckgasanschluss auf. So ist beispielsweise das Dosieren von Inertgas vorgesehen. Nach einem Entleeren sind die erfindungsgemäßen flexiblen Gebinde zu entsorgen. Zur besseren Kontrollierbarkeit eines solchen Abfalls kann durch die oben erwähnten Öffnungen gezielt vakuumiert werden.Apart from these connections, which are material-impermeable in the interior of the container, for clamping at least wall regions corresponding to a defined shape, the container 20 has at least one docking connection for filling and emptying. For this purpose, a coupling element 22 is shown, which in a simple Form simply a ring can be. But it can also be provided not only above but also below such an opening. You must be able to aerate the container to achieve its desired shape, if necessary metered. For this purpose, the container preferably has a valve opening or a compressed gas connection. For example, the metering of inert gas is provided. After emptying, the flexible containers according to the invention are to be disposed of. For better controllability of such a waste can be selectively vacuumed through the above-mentioned openings.

Zum weiteren Explosionsschutz sind erfindungsgemäß sowohl das Gebinde wie auch das Gestell mit Erdungslaschen ausgerüstet.For further explosion protection both the container and the frame are equipped with earthing straps according to the invention.

Das dargestellte Ausführungsbeispiel des erfindungsgemäßen Gebindes hat einen quadratischen Boden 24 und an dessen Seiten anschließend Dreieckstümpfe als Seitenwände 26. Gemeinsam bilden sie eine nach oben offene Pyramidenform aus. Die Erfindung umfasst auch andere Formen, wie Kugeln oder Oktaeder, die in ihren Grundformen zumindest teilweise angenähert werden können, indem erfindungsgemäß zumindest Teilflächen des Gebindes aufgespannt werden.The illustrated embodiment of the container according to the invention has a square bottom 24 and at its sides then truncated triangles as side walls 26. Together they form an upwardly open pyramidal shape. The invention also includes other forms, such as spheres or octahedra, which can be approximated in their basic forms at least partially by at least partial surfaces of the container are clamped according to the invention.

Dem Boden 24 gegenüber bietet das flexible Gebinde nach den Darstellungen ein Kupplungselement 22 das flexible Gebinde 20 standardisiert abdichtbar an seinen öffnungsseitige Enden 28 der Seitenwände 26 angeschlossen das Kupplungselement 22 an.Opposite the bottom 24, the flexible container according to the illustrations provides a coupling element 22, the flexible container 20 standardized sealable connected to its opening-side ends 28 of the side walls 26, the coupling element 22 at.

Zum Aufspannen von Teilflächen nach außen sind nach bevorzugten Ausführungsformen des Gebindes 20 den Verbindungslinien zwischen den Seitenwänden 26 folgend Taschen 25 als Längsführungen ausgebildet. In sie können Stäbe des Gestells eingeführt werden, bevorzugt beim Ablassen des Gebindes in das Gestell 10. Die Stäbe, nicht dargestellt sind bevorzugt unten drehbar um eine Strebe des Gestells gelagert. Oben haben Sie nach dem Aufführen freie Enden, die in das Kupplungselement eingerastet werden.For clamping of partial surfaces to the outside, according to preferred embodiments of the container 20, the connecting lines between the side walls 26 following pockets 25 are formed as longitudinal guides. In it rods of the frame can be introduced, preferably when draining the container into the frame 10. The rods, not shown, are preferably mounted below rotatable about a strut of the frame. At the top, after threading, you have free ends that snap into the coupling element.

Das Gestell kann aber auch alleine mit Spannflächen des Gestells in eine bestimmte Form gezwungen werden.The frame can also be forced alone with clamping surfaces of the frame in a particular form.

Die Erfindung ermöglicht es demnach Schüttgüter ohne weiteres Umfüllen in genormte Stahlbehälter zu behandeln. Beispielhaft nennt die Erfindung das Mischen des Schüttgutes in einem flexiblen Gebinde, wobei das flexible Gebinde in einem Gestell aufgespannt wird, um zumindest beinahe eine definierte Körperform zwangsweise anzunehmen. Das Gestell wird dann in Mischern bewegt, wie sonst die bekannten Starren Mischbehälter einzuspannen waren.The invention thus makes it possible to treat bulk materials without further refilling in standardized steel containers. By way of example, the invention mentions the mixing of the bulk material in a flexible container, wherein the flexible container is mounted in a frame in order to forcibly adopt at least almost a defined body shape. The rack is then moved in mixers as otherwise the known rigid mixing bowls were to be clamped.

Vorteilhafte Verfahren nach der Erfindung sorgen für ein Anschmiegen oder anderweitiges Aufspannen der Seitenwände und / oder des Bodens des flexiblen Gebindes zu flachen Teilflächen.Advantageous methods according to the invention provide for nestling or otherwise clamping the side walls and / or the bottom of the flexible container to flat partial surfaces.
