Description

Die Erfindung betrifft ein modulares Rührwerk welches einen Antrieb, eine Rührwerkseinheit, sowie eine Magnetkupplung aufweist, wobei die Magnetkupplung zwischen Antrieb und Rührwerkseinheit angeordnet ist, und einen zylindrischen Hohlraum, Antriebsmagnete sowie Rührwerkseinheitmagnete aufweist, wobei die Antriebsmagnete mit dem Antrieb verbunden sind und die Rührwerkseinheitmagnete mit der Rührwerkseinheit verbunden und radial um den Hohlraum angeordnet sind, wobei der Hohlraum im geöffneten Zustand der Magnetkupplung an seinem der Rührwerkseinheit im Wesentlichen gegenüberliegenden Ende offen ist, und zum Schließen der Magnetkupplung zur Koppelung von Antrieb und Rührwerkseinheit die Antriebsmagnete in den Holraum der Magnetkupplung einführbar, und im Wesentlichen in einer Ebene mit den Rührwerksmagneten anordenbar sind.The invention relates to a modular agitator which has a drive, an agitator unit and a magnetic coupling, the magnetic coupling being arranged between the drive and agitator unit, and having a cylindrical cavity, drive magnets and agitator unit magnets, the drive magnets being connected to the drive and the agitator unit magnets being are connected to the agitator unit and are arranged radially around the cavity, the cavity being open in the open state of the magnetic coupling at its end substantially opposite the agitator unit, and to close the magnetic coupling for coupling the drive and agitator unit, the drive magnets can be inserted into the cavity of the magnetic coupling, and can be arranged essentially in one plane with the agitator magnets.

Ein derartiges modulares Rührwerk wird beispielsweise in der Lebensmittelindustrie, insbesondere im Bereich der Fruchtzubreitung eingesetzt. Fruchtmischungen sind in der Regel hoch-viskose Flüssigkeiten welche Fruchtstücke enthalten. Diese werden in der Regel an einem Befüllungsstandort in Edelstahlbehälter abgefüllt, welche nach der Befüllung zur Weiterverwendung an den nächsten Produktionsstandort transportiert werden. Die Behälter werden bis zur Befüllung bzw. bis zur Weiterverarbeitung des Inhaltes am Befüllungsstandort bzw. am Produktionsstandort möglichst platzsparend gelagert.
Nach der Verwendung werden die Behälter gereinigt, aseptisch wieder aufbereitet und stehen dann für eine Neubefüllung zur Verfügung. Auch hierbei ist eine möglichst platzsparende Lagerhaltung gereinigter bzw. ungereinigter Behälter notwendig. Insbesondere bei niedrigviskosen Fruchtmischungen setzen sich allerdings Fruchtstücke am Boden der Behälter ab, wodurch die Mischung inhomogen wird. Es ist somit notwendig vor einer Weiterverarbeitung die Mischung erneut im Behälter zu homogenisieren ohne diesen zu öffnen, da die Fruchtmischung keimfrei zu halten ist.Such a modular agitator is used, for example, in the food industry, in particular in the field of fruit preparation. Fruit mixes are usually highly viscous liquids that contain pieces of fruit. These are usually filled at a filling location in stainless steel containers, which are then transported to the next production location for further use. The containers are stored as space-saving as possible until filling or further processing of the contents at the filling location or at the production location.
After use, the containers are cleaned, reprocessed aseptically and are then available for refilling. Here too, space-saving storage of cleaned or uncleaned containers is necessary. In the case of low-viscosity fruit mixtures in particular, however, pieces of fruit settle on the bottom of the containers, as a result of which the mixture becomes inhomogeneous. It is therefore necessary to homogenize the mixture in the container again before further processing without opening it, since the fruit mixture must be kept germ-free.

Hierzu existieren am Markt Behälter mit integrierten Rührwerken, wobei diese mit einer Gleitringdichtung versehen sind. Für sterile Prozesse stellt diese allerdings eine Gefahrenquelle dar, da bei Abnutzung und Verschleiß der Dichtung die Möglichkeit der Kontamination des Produkts besteht. Dies würde dazu führen, dass das Endprodukt, welches aus der Fruchtmischung hergestellt wird, verworfen werden muss.For this purpose there are containers with integrated agitators on the market, which are provided with a mechanical seal. However, this represents a source of danger for sterile processes, since the seal can wear out and wear out There is contamination of the product. This would mean that the end product, which is made from the fruit mixture, must be discarded.

Die EP 1 748 201 B1 offenbart einen Magnetrührer, welcher eine magnetische Kupplung zwischen Antrieb und Rührwerk aufweist, wodurch die Gleitringdichtung entfallen kann, und das Risiko der Kontamination des Produkts durch die Dichtung entfällt. Das Antriebssystem ist bei der EP 1 748 201 B1 am Behälter mittels einer Anzahl von Schrauben befestigt.The EP 1 748 201 B1 discloses a magnetic stirrer which has a magnetic coupling between the drive and the agitator, as a result of which the mechanical seal can be dispensed with and the risk of contamination of the product by the seal is eliminated. The drive system is at the EP 1 748 201 B1 attached to the container by means of a number of screws.

Als Nachteilig hat sich in derartigen Konstruktionen erwiesen, dass die Behälter durch Ihre Form einen erheblichen Platzbedarf bei der Lagerung aufweisen, was die Lagerhaltungskosten erhöht. Des Weiteren verursacht das mit den Behältern verbundene Antriebssystem erhöhte Anschaffungskosten und begrenzt die Lebensdauer der Behälter.It has proven to be a disadvantage in such constructions that the shape of the containers requires a considerable amount of space during storage, which increases the storage costs. Furthermore, the drive system connected to the containers causes increased acquisition costs and limits the life of the containers.

Die US 2004/076076 A1 offenbart ein Rührwerk mit Magnetkupplung.The US 2004/076076 A1 discloses an agitator with magnetic coupling.

Die US 5 478 149 A offenbart einen Magnetrührer mit einer Magnetkupplung mit Schnell Verschluss.The US 5,478,149A discloses a magnetic stirrer with a magnetic coupling with quick release.

Es ist die Aufgabe der vorliegenden Erfindung ein modulares Rührwerk zu bilden, das die Nachteile der oben aufgeführten Konstruktionen vermeidet.It is the object of the present invention to form a modular agitator which avoids the disadvantages of the constructions listed above.

Erfindungsgemäß wird die vorliegende Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention, the present object is achieved by the features of claim 1.

Das Rührwerk wird in den Behälterdeckel integriert, welcher auf verschiedene Behältergrößen passt.The agitator is integrated into the container lid, which fits different container sizes.

Durch die erfindungsgemäße Ausführung des Rührwerks, insbesondere durch dessen modularen Aufbau in Verbindung mit der einfach zu lösenden Verbindung von Behälter und Antrieb ist der Behälter unabhängig vom Antrieb. Hierdurch wird der Vorteil erhalten, dass ein Antrieb für eine Vielzahl von Behältern genutzt werden kann. Folglich reduziert sich die Anzahl der notwendigen Antriebe für eine bestimmte Anzahl von Behältern, wobei die Antriebe am jeweiligen Produktionsstandort verbleiben können. Des Weiteren kann bei einem Ausfall eines Antriebs dieser einfach ersetzt werden, wodurch Stillstandszeiten im Produktionsprozess reduziert werden. Insbesondere vorteilhaft ist, dass hierdurch auch die Lebensdauer der Behälter erhöht wird.Due to the design of the agitator according to the invention, in particular due to its modular structure in connection with the easily detachable connection of the container and the drive, the container is independent of the drive. This has the advantage that a drive can be used for a large number of containers. As a result, the number of drives required for a certain number of containers is reduced, and the drives can remain at the respective production site. Furthermore, with one Failure of a drive can easily be replaced, reducing downtimes in the production process. It is particularly advantageous that this also increases the life of the containers.

Weiters ist es vorteilhaft, dass durch eine derartige Konstruktion die Anschaffungskosten der Behälter durch den vom jeweiligen Behälter unabhängigen Antrieb reduziert werden.Furthermore, it is advantageous that the construction costs of the containers are reduced by such a construction by the drive independent of the respective container.

Ein weiterer Vorteil der vorliegenden Erfindung besteht darin, dass durch die einfache Demontage des Antriebs von den Behältern eine Stapelung der Behälter ermöglicht wird, wodurch eine platzsparende Lagerung gewährleistet werden kann.Another advantage of the present invention is that the simple disassembly of the drive from the containers enables the containers to be stacked, thereby ensuring space-saving storage.

Des Weiteren ist es vorteilhaft, dass der Reinigungsprozess der Behälter durch den Wegfall eines fix verbundenen Antriebs wesentlich erleichtert wird.Furthermore, it is advantageous that the cleaning process of the containers is made considerably easier by the omission of a permanently connected drive.

Figur 1 zeigt eine bevorzugte Ausführungsvariante einer Magnetkupplung 1 eines erfindungsgemäßen modularen Rührwerks 2 im geschlossenen Zustand. Das Rührwerk 2 besteht aus einem Antrieb 3, einer Rührwerkseinheit 4, sowie der dazwischenliegenden Magnetkupplung 1. Der Antrieb 3 und die Rührwerkseinheit 4 sind in Figur 1 zur besseren Darstellung der Magnetkupplung 1 nur abschnittweise gezeigt. Die Magnetkupplung 1 ist aus einem Hohlraum 5 aufgebaut, in welchem sich im geschlossenen Zustand der Magnetkupplung 1 Antriebsmagnete 6 befinden. Radial um den Hohlraum 5 sind in der Ebene der Antriebsmagnete 6 Rührwerkeinheitsmagnete 7 angeordnet. Im geschlossenen Zustand der Magnetkupplung 1 wird das Drehmoment des Antriebs 3 durch die magnetische Anziehung der Antriebsmagnete 6 und der Rührwerkeinheitsmagnete 7 vom Antrieb 3 auf die Rührwerkseinheit 4 übertragen.
Bei der Öffnung der Magnetkupplung 1 werden die Antriebsmagnete 6 aus dem Hohlraum 5 entfernt, wobei dieser hierzu mittels eines Schnellverschlusses 8 geöffnet wird.
Die Verbindung von Antrieb 3 und Rührwerkseinheit 4 erfolgt beim Schließen der Magnetkupplung 1, wobei die Antriebsmagnete 6 in den Hohlraum 5 eingeführt werden und in der Ebene der Rührwerkeinheitsmagnete 7 angeordnet werden. Hierbei wird der Hohlraum 5 mittels des Schnellverschlusses 8 verschlossen.
Hierdurch wird der Vorteil erhalten, dass der Antrieb 3 auf einfache Weise mit der Rührwerkseinheit 4 verbunden und auch wieder von dieser entfernt werden kann. Die Verwendung einer Magnetkupplung 1 ist vorteilhaft, da diese keine zusätzlichen Dichtungen nötig macht, welche eine potentiell Gefahrenquelle für die Keimfreiheit des Behälterinhalts darstellen. Figure 1 shows a preferred embodiment of a magnetic coupling 1 of a modular agitator 2 according to the invention in the closed state. The agitator 2 consists of a drive 3, an agitator unit 4 and the magnetic coupling 1 located therebetween. The drive 3 and the agitator unit 4 are shown in FIG Figure 1 only shown in sections for better illustration of the magnetic coupling 1. The magnetic coupling 1 is constructed from a cavity 5, in which drive magnets 6 are located when the magnetic coupling 1 is closed. Radially around the cavity 5 6 stirrer unit magnets 7 are arranged in the plane of the drive magnets. In the closed state of the magnetic clutch 1, the torque of the drive 3 by the magnetic Transfer attraction of the drive magnets 6 and the agitator unit magnets 7 from the drive 3 to the agitator unit 4.
When the magnetic coupling 1 is opened, the drive magnets 6 are removed from the cavity 5, the latter being opened for this purpose by means of a quick release 8.
The drive 3 and the agitator unit 4 are connected when the magnetic coupling 1 is closed, the drive magnets 6 being introduced into the cavity 5 and being arranged in the plane of the agitator unit magnets 7. Here, the cavity 5 is closed by means of the quick release 8.
This has the advantage that the drive 3 can be connected to the agitator unit 4 in a simple manner and can also be removed from it. The use of a magnetic coupling 1 is advantageous since it does not require any additional seals, which represent a potential source of danger for the container being sterile.

Der Schnellverschluss 8 kann einer aus verschiedenen Schnellverschlüssen sein, wobei bevorzugterweise ein Bajonettverschluss, eine Überwurfmutter, ein Milchrohrverschluss oder ein TC-Verschluss zur Anwendung kommt.
Die Verwendung dieser Schnellverschlüsse ist besonders vorteilhaft, da diese auf dem Markt in großer Anzahl verfügbar sind und kein komplexes, spezielles Werkzeug benötigen um geöffnet bzw. geschlossen zu werden. Hierdurch wird zusätzlich die Handhabung erleichtert.The quick-release fastener 8 can be one of different quick-release fasteners, a bayonet fastener, a union nut, a milk pipe fastener or a TC fastener preferably being used.
The use of these quick-release fasteners is particularly advantageous because they are available in large numbers on the market and do not require a complex, special tool to be opened or closed. This also makes handling easier.

Die in Figur 1 dargestellte Magnetkupplung 1 weist eine Trennebene 9 auf in welcher die Magnetkupplung 1 getrennt werden kann. In dieser ist eine Anzahl von Stiften 10 angeordnet, welche in entsprechende Ausnehmungen des gegenüberliegenden Magnetkupplungsteiles beim Schließen der Magnetkupplung 1 greifen.
Hierdurch wird der Vorteil erreicht, dass die Magnetkupplung 1 durch die Stifte 10 zusätzlich gegen eventuell auftretende Belastungen wie Vibrationen oder Querbelastungen versteift wird.In the Figure 1 Magnetic coupling 1 shown has a parting plane 9 in which the magnetic coupling 1 can be separated. A number of pins 10 are arranged in this, which engage in corresponding recesses in the opposite magnetic coupling part when the magnetic coupling 1 is closed.
This achieves the advantage that the magnetic coupling 1 is additionally stiffened by the pins 10 against possible loads such as vibrations or transverse loads.

Das in Figur 2 in einer Schnittansicht in der Frontalebene dargestellte modulare Rührwerk 2 ist, wie in Figur 4 dargestellt, bevorzugterweise Teil eines Behälters 11, wobei dieser aus einem Behälterdeckel 12 und einem Behälterkörper 13 aufgebaut ist. Figur 2 stellt das gesamte modulare Rührwerk 2 in einer bevorzugten Ausführungsvariante mit vollständigem Antrieb 3 und Rührwerkseinheit 4 dar, welche in Figur 1 nur abschnittsweise dargestellt werden. Die Magnetkupplung 1 des modularen Rühwerks 2 ist hierzu wie in Figur 3 im Detail dargestellt in den Behälterdeckel 12 integriert, wobei dieser den Hohlraum 5 der Magnetkupplung 1 unterhalb der Trennebene 9 der Magnetkupplung 1 umschließt.
Durch diesen Aufbau wird der Vorteil erreicht, dass das modulare Rührwerk 2 durch die Kombination einheitlicher Behälterdeckel 12 mit Behälterkörpern 13 unterschiedlichen Fassungsvermögens in Behälter 11 verschiedener Größen integriert werden kann.This in Figure 2 is a modular agitator 2 shown in a sectional view in the frontal plane, as in Figure 4 shown, preferably part of a container 11, which is constructed from a container lid 12 and a container body 13. Figure 2 represents the entire modular agitator 2 in a preferred embodiment with a complete drive 3 and agitator unit 4, which in Figure 1 only shown in sections become. For this purpose, the magnetic coupling 1 of the modular agitator 2 is as in Figure 3 Shown in detail in the container lid 12, which encloses the cavity 5 of the magnetic coupling 1 below the parting plane 9 of the magnetic coupling 1.
This construction achieves the advantage that the modular agitator 2 can be integrated into containers 11 of different sizes by combining uniform container lids 12 with container bodies 13 of different capacities.

Figur 3 zeigt eine Schnittansicht in der Frontalebene eines modulares Rührwerks 2, in einer bevorzugten Ausführungsvariante, wobei der Antrieb 3 durch Trennung der Magnetkupplung 1 entfernt wurde. Das modulare Rührwerk 2 ist vom Behälterdeckel 12 umschlossen, welcher so wie die Rührwerkseinheit 4 nur abschnittsweise dargestellt ist. Der Hohlraum 5 der Magnetkupplung 1 ist in Figur 3 im geschlossenen Zustand in Frontalansicht dargestellt. Hierzu ist im getrennten Zustand der Magnetkupplung 1 ein Verschluss 14 auf die Trennebene 9 der Magnetkupplung 1 aufgesetzt.
Hierdurch wird der Vorteil erhalten, dass der Hohlraum 5 der Magnetkupplung 1 durch das Aufsetzen des Verschlusses 14 nicht verschmutzt wird. Figure 3 shows a sectional view in the frontal plane of a modular agitator 2, in a preferred embodiment variant, the drive 3 having been removed by separating the magnetic coupling 1. The modular agitator 2 is enclosed by the container lid 12, which, like the agitator unit 4, is only shown in sections. The cavity 5 of the magnetic coupling 1 is in Figure 3 shown in the closed state in frontal view. For this purpose, a closure 14 is placed on the parting plane 9 of the magnetic coupling 1 when the magnetic coupling 1 is disconnected.
This has the advantage that the cavity 5 of the magnetic coupling 1 is not contaminated by the attachment of the closure 14.

Der Verschluss 14 kann einer aus verschiedenen Verschlüssen sein, wobei bevorzugterweise ein Bajonettverschluss, eine Überwurfmutter, ein Milchrohrverschluss oder ein TC-Verschluss zur Anwendung kommt.
Die Verwendung dieser Verschlüsse ist besonders vorteilhaft, da diese auf dem Markt in großer Anzahl verfügbar sind und kein komplexes, spezielles Werkzeug benötigen um geöffnet bzw. geschlossen zu werden. Hierdurch wird zusätzlich die Handhabung erleichtert.The closure 14 can be one of various closures, a bayonet closure, a union nut, a milk tube closure or a TC closure preferably being used.
The use of these closures is particularly advantageous since they are available in large numbers on the market and do not require a complex, special tool to be opened or closed. This also makes handling easier.

Figur 4 zeigt zwei Behälter 11 mit einem erfindungsgemäßen modularen Rührwerk 2 mit getrennter Magnetkupplung 1 und Verschluss 14 in einer Frontalansicht, welche aufeinander gestapelt sind. Der untere der beiden Behälter 11 ist zur Darstellung des darin integrierten modularen Rührwerks 2 in einer aufgeschnittenen Darstellung gezeigt.
Durch die Möglichkeit der Abnahme des Antriebs 3 von den Behältern 11 ist es möglich diese wie in Figur 4 dargestellt aufeinander zu stapeln.
Hierdurch ergibt sich der Vorteil, dass ein geringerer Platzbedarf für die Lagerhaltung von Behältern 11 notwendig ist, wodurch Lagerhaltungskosten reduziert werden. Figure 4 shows two containers 11 with a modular agitator 2 according to the invention with separate magnetic coupling 1 and closure 14 in a frontal view, which are stacked on top of one another. The lower of the two containers 11 is shown in a cut-away representation to show the modular agitator 2 integrated therein.
The possibility of removing the drive 3 from the containers 11 makes it possible as in FIG Figure 4 illustrated stacking on top of each other.
This has the advantage that less space is required for the storage of containers 11, which reduces storage costs.
