Description

Die Erfindung bezieht sich auf eine Füllvorrichtung für oben offene Gebinde, vorzugsweise für Säcke, die mit einem pulverförmige Produkt zu befüllen sind, nach dem Oberbegriff des Anspruchs 1.The invention relates to a filling device for open-topped containers, preferably for bags to be filled with a powdery product, according to the preamble of claim 1.

Eine derartige Füllvorrichtung ist aus der WO 2005/110849 A2 bekannt.Such a filling device is from the WO 2005/110849 A2 known.

Pulverförmige Produkte haben in der Regel die Eigenschaft, dass sie während der Herstellung, des Transportes und auch während des Füllvorganges auch Luft aufnehmen, wodurch sich das Volumen vergrößert. Die in Rede stehenden Füllvorrichtungen zum Füllen von Gebinden sollten daher vorzugsweise so ausgelegt sein, dass die aufgenommene Luft zumindest teilweise wieder abgegeben wird.Powdered products usually have the property that they also absorb air during manufacture, transport and during the filling process, which increases the volume. The filling devices in question for filling containers should therefore preferably be designed so that the intake air is at least partially released again.

Um den Anteil der Restluft im Produkt so gering wie möglich zu halten, ist vorgeschlagen worden, Innenrüttler einzusetzen, die in das Gebinde eingebracht werden und dort durch Rüttelbewegungen das Produkt verdichten (siehe die DE 89 10 081.6 U1 ).In order to keep the proportion of residual air in the product as low as possible, it has been proposed to use internal vibrators, which are introduced into the container and there compact the product by shaking movements (see US Pat DE 89 10 081.6 U1 ).

Als Innenrüttler werden auch sogenannte Rüttelflaschen eingesetzt. Rüttelflaschen sind an sich aus dem Stand der Technik bekannt, so zum Herstellen von Bohrlöchern. Eine derartige Lösung zeigt die AT 21 46 22 PS . Eine weitere Rüttelflasche ist aus der US 2,148,722 bekannt. Ein Einsatz dieser Rüttelflaschen an Füllmaschinen zum Verdichten des Füllgutes von Gebinden an Füllmaschinen war bisher nicht erfolgreich, da die Leistungsfähigkeit den Anforderungen nicht genügte.As internal vibrators and so-called vibrating bottles are used. Vibrating bottles are known per se from the prior art, such as for the production of boreholes. Such a solution shows the AT 21 46 22 hp , Another jar is from the US 2,148,722 known. A use of these vibrating bottles of filling machines for compacting the contents of containers to filling machines has not been successful, since the performance did not meet the requirements.

Die Rüttelflaschen sind mit einem Schwingungserreger ausgestattet, der in der Regel von einer außerhalb des Gebindes angeordneten Antriebsvorrichtung angetrieben wird. Der Schwingungserreger ist eine Unwuchtmasse, die auf einer rotierend antreibbaren Welle festgesetzt ist. Die Welle wird von der Antriebsvorrichtung über eine weitere, flexible Welle angetrieben. Der Vorteil einer solchen Ausführung ist darin zu sehen, dass die in Schwingung zu versetzenden Massen relativ gering sind. Dabei ist die flexible Welle von einem flexiblen Schutzschlauch umgeben. Diese flexible Auslegung verhindert es, dass der Innenrüttler innerhalb des Gebindes mittig zu platzieren ist, was dazu führt, dass das Produkt innerhalb des Gebindes ungleichmäßig verdichtet wird. Darüber hinaus kann der Innenrüttler nach dem Herausziehen aus dem Gebinde noch nachschwingen, wodurch die Gefahr besteht, dass der Füllstutzen der Füllvorrichtung beschädigt wird.The Rüttelflaschen are equipped with a vibration exciter, which is usually driven by a arranged outside the container drive device. The vibration generator is an imbalance mass, which is fixed on a rotating drivable shaft. The shaft is driven by the drive device via a further, flexible shaft. The advantage of such an embodiment can be seen in the fact that the masses to be vibrated are relatively small. The flexible shaft is surrounded by a flexible protective tube. This flexible design prevents the internal vibrator from being centered within the container, causing the product to be unevenly compressed within the container. In addition, the internal vibrator after swinging out of the container still resonate, creating the risk that the filler neck of the filling device is damaged.

Es ist deshalb auch schon vorgeschlagen worden, dass die Verbindung zwischen dem Innenrüttler und der Antriebsvorrichtung starr ausgelegt wird. Dies bringt das Problem mit sich, dass die gesamte Baueinheit, bestehend aus dem Innenrüttler, der starren Verbindung und der Antriebsvorrichtung vom Schwingungserreger in Schwingungen versetzt werden muß, wodurch die zu bewegende Masse relativ hoch ist. Dies führt wiederum zu einer thermischen Belastung der Lager der die Unwuchtmassen tragenden Wellen. Würde man zur Verringerung dieser Belastung der Lager die Drehzahl der Welle reduzieren, würde die Verdichtung verschlechtert.It has therefore also been proposed that the connection between the internal vibrator and the drive device is designed to be rigid. This involves the problem that the entire assembly consisting of the internal vibrator, the rigid connection and the drive device must be vibrated by the vibration exciter, whereby the mass to be moved is relatively high. This in turn leads to a thermal load on the bearing of the waves carrying the imbalance masses. If one were to reduce the speed of the shaft to reduce this load on the bearings, the compression would be deteriorated.

Der Erfindung liegt die Aufgabe zugrunde, eine Füllvorrichtung der eingangs näher beschriebenen Art so zu gestalten, dass eine optimale Verdichtung des in das Gebinde eingefüllten Produktes gewährleistet ist. Vorzugsweise soll auch die thermische Belastung der Lager der die Unwuchtmassen tragenden Welle so gering wie möglich gehalten werden.The invention has for its object to make a filling device of the type described in more detail so that optimal compression of the filled product in the container is guaranteed. Preferably, the thermal load of the bearing of the shaft bearing the imbalance masses should be kept as low as possible.

Zur Lösung der gestellten Aufgabe ist vorgesehen eine Füllvorrichtung gemäß Anspruch 1, wobei die flexible Welle zumindest abschnittsweise von einem starren Führungsrohr umgeben ist. Bevorzugt ist dabei ein Abschnitt der flexiblen Welle vor der Rütteleinrichtung nicht von dem starren Führungsrohr umgeben.To achieve the object is provided a filling device according to claim 1, wherein the flexible shaft is at least partially surrounded by a rigid guide tube. In this case, a section of the flexible shaft in front of the vibrating device is preferably not surrounded by the rigid guide tube.

Hierdurch wird eine gute Führung der Welle gewährleistet, die nach der Erkenntnis der Erfindung einer Führung bedarf, um im Gebinde mittig platziert werden zu können. Durch den verbleibenden Abschnitt der flexiblen Welle wird dennoch weiter eine genügende Schwingung erlaubt, um das abzufüllende Produkt zu verdichten.As a result, a good guidance of the shaft is guaranteed, which requires the knowledge of the invention, a guide to be placed centrally in the container can. The remaining portion of the flexible shaft still allows sufficient vibration to compress the product to be filled.

Da das Führungsrohr starr ist, wird der Innenrüttler exakt innerhalb des Gebindes positioniert. Dadurch wird eine optimale und gleichmäßige Verdichtung des Produktes erreicht. Außerdem werden die in Schwingungen zu versetzenden Massen so gering wie möglich gehalten, so dass die thermische Belastung der Lager innerhalb des Innenrüttlers so gering wie möglich gehalten wird. Darüber hinaus wird beim Herausfahren des Innenrüttlers aus dem Gebinde der Füllstutzen gegen eine Beschädigung gesichert.Since the guide tube is rigid, the internal vibrator is positioned exactly within the container. As a result, an optimal and uniform compression of the product is achieved. In addition, the masses to be vibrated are kept as low as possible, so that the thermal load of the bearings within the internal vibrator is kept as low as possible. In addition, when removing the internal vibrator from the container, the filler neck is secured against damage.

Der Schwingungserreger des Innenrüttlers wird mit der flexiblen Welle angetrieben, wobei das Führungsrohr vorzugsweise starr mit der Antriebsvorrichtung verbunden ist.The vibrator of the internal vibrator is driven by the flexible shaft, wherein the guide tube is preferably rigidly connected to the drive device.

Vorzugsweise ist das starre Führungsrohr dabei an der Antriebsvorrichtung befestigt.Preferably, the rigid guide tube is attached to the drive device.

In besonders vorteilhafter Weise ist der Innenrüttler an der flexiblen Welle festgelegt. Dadurch ist sichergestellt, dass das die flexible Welle umgebende Führungsrohr nicht in Schwingungen versetzt wird.In a particularly advantageous manner, the internal vibrator is fixed to the flexible shaft. This ensures that the guide tube surrounding the flexible shaft is not vibrated.

Vorzugsweise ist vorgesehen, dass bei einer Füllvorrichtung der eingangs näher beschriebenen Art der Mantel des Innenrüttlers aus einem metallischen oder nichtmetallischen Werkstoff besteht, dessen Dichte - vorzugsweise deutlich - unter der von Eisen liegt, beispielsweise aus einem Leichtmetall wie z.B. Aluminium besteht.Preferably, it is provided that in a filling device of the type described in more detail above, the sheath of the internal vibrator consists of a metallic or non-metallic material whose density is preferably less than that of iron, for example a light metal, such as e.g. Aluminum is made.

Dadurch wird die in Schwingung zu versetzende Masse entsprechend gering gehalten. Dadurch wird die Belastung für die die Unwuchtmassen tragenden Welle deutlich verringert. Es können jedoch auch nichtmetallische Werkstoffe verwendet werden. Solche Werkstoffe sind beispielsweise Verbundwerkstoffe mit einem bestimmten Anteil eines Kunststoffes, keramische Werkstoffe oder Warmstrukturwerkstoffe. Durch die Kombination von Werkstoffen bei Verbundwerkstoffen oder durch die Hohlräume bei Warmstrukturwerkstoffen wird die Dichte deutlich gesenkt.As a result, the mass to be vibrated is kept correspondingly low. As a result, the burden on the shaft bearing the imbalance masses is significantly reduced. However, non-metallic materials can also be used. Such materials are, for example, composites with a certain proportion of a plastic, ceramic materials or thermal structure materials. The combination of materials in composite materials or through the cavities of thermo-structural materials significantly reduces the density.

Durch die Kombination des Werkstoffes und der Bauform wird ein materialspezifisch optimales Massenverhältnis gebildet, so dass die Belastung der Lager und damit die thermische Belastung minimiert sind. Einer übermäßigen Erwärmung der Lager wird damit entgegengesteuert. Eine hohe Verdichtung auch in kurzer Zeit ist damit kein Problem. Dies wirkt sich insbesondere auch vorteilhaft bei der Abfüllung von Produkten aus, die im Moment der Abfüllung noch relativ warm sind.By combining the material and the design, a material-specific optimum mass ratio is formed, so that the load on the bearings and thus the thermal load are minimized. An excessive heating of the bearings is thus counteracted. A high compression in a short time is no problem. This also has an advantageous effect on the filling of products that are still relatively warm at the moment of filling.

Es ist weiterhin bevorzugt vorgesehen, dass der Innenrüttler mittels eines steuerbaren Antriebes in vertikaler Richtung zeitgesteuert verfahrbar ist. Diese Weiterentwicklung und auch eigenständige Erfindung spiegelt sich in dem nebengeordneten Verfahrensanspruch wieder, nach welchem die Rütteleinrichtung beim Verdichten des Produktes zeitgesteuert bzw. verzögert, insbesondere stufenweise, aus dem Gebinde angehoben wird. Dadurch besteht die Möglichkeit, dass der Innenrüttler nach und nach langsam, insbesondere in mehreren Stufen, aus dem Gebinde herausgefahren werden kann. Auf diese Weise wird der durch den Innenrüttler gebildete und nach dem Hochfahren darunterliegende Hohlraum sofort mit dem Produkt gefüllt, so dass sich keine Hohlräume zurückbleiben. Im gesamten Gebinde kann das Produkt gezielt verdichtet werden. So ist es auch vorteilhaft, dass mittels des Innenrüttlers auch das im Gebinde unmittelbar unterhalb der Einfüllöffnung liegende Produkt verdichtet wird. Dies ist besonders wichtig, da auf diesen Bereich des Produktes quasi kein Eigendruck mehr ausgeübt wird.It is furthermore preferably provided that the internal vibrator can be moved in a time-controlled manner by means of a controllable drive in the vertical direction. This development and independent invention is reflected in the sibling method claim again, after which the vibrator is time-controlled or delayed, especially in stages, lifted from the container during the compression of the product. As a result, there is the possibility that the internal vibrator can gradually be moved out of the container slowly, in particular in several stages. In this way, the cavity formed by the internal vibrator and below it after startup is immediately filled with the product so that no cavities remain. The product can be compacted in the entire container. So it is also advantageous that by means of the internal vibrator and the product lying in the container immediately below the filling opening is compressed. This is particularly important, as this area of the product virtually no more self-pressure is exerted.

Eine optimale Verdichtung ist zudem gegeben, wenn die Rütteleinrichtung nicht nur aus dem Innenrüttler besteht, sondern wenn sich das Gebinde bzw. der Sack zumindest während des Füllvorganges auf einem Rütteltisch abstützt.An optimal compression is also given if the vibrator not only consists of the internal vibrator, but if the container or the bag is supported at least during the filling process on a vibrating table.

Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert.Reference to the accompanying drawings, the invention will be explained in more detail.

Aus Gründen der vereinfachten Darstellung ist von der erfindungsgemäßen Füllvorrichtung nur die Rütteleinrichtung einschließlich des Antriebes zum Verfahren in vertikaler Richtung dargestellt. Die Rütteleinrichtung besteht aus einem Innenrüttler 10 in Form einer Rüttelflasche und einem Rütteltisch 11. Der nicht dargestellte Schwingungserreger des Innenrüttlers 10 wird von einer Antriebsvorrichtung 12 in Drehung versetzt.For reasons of simplified illustration of the filling device according to the invention, only the vibrating device including the drive for the process in the vertical direction is shown. The vibrator consists of an internal vibrator 10 in the form of a vibrating bottle and a vibrating table 11. The vibrator, not shown, of the internal vibrator 10 is rotated by a drive device 12 in rotation.

Mittels eines weiteren Antriebes 13 werden die Antriebsvorrichtung 12 und der Innenrüttler 10 nach Art einer Hubvorrichtung höhenverschieblich längs einer vertikalen Führungsbahn 19 verfahren. Die Führungsbahn 19 ist an einer Säule 14 angeordnet, die Bestandteil eines ansonsten nicht dargestellten Maschinengestells ist. Wie die Figur 1 zeigt, kann der Innenrüttler 10 so weit abgesenkt werden, dass er vollständig in ein Gebinde 15 eintaucht. Bevorzugt ist das Gebinde 15 ein Sack, der aus einer Kunststofffolie gefertigt ist.By means of a further drive 13, the drive device 12 and the internal vibrator 10 are moved in a height-displaceable manner along a vertical guide track 19 in the manner of a lifting device. The guideway 19 is arranged on a column 14, which is part of an otherwise not shown machine frame. As the FIG. 1 shows, the internal vibrator 10 can be lowered so far that it is completely immersed in a container 15. Preferably, the container 15 is a bag which is made of a plastic film.

Die Figur 2 zeigt, dass der Schwingungserreger des Innenrüttlers 10 über eine flexible bzw. biegsame Welle 17 angetrieben wird. Außerdem zeigt die Figur, dass die flexible Welle 17 innerhalb eines Schutzschlauches 16 angeordnet ist. Diese Einheit ist nach Fig. 2 in einer Gleitführung eines Führungsrohres 18 geführt, das starr ist und feststehend - hier an einem Klemmverbinder 20 - angeordnet ist.The FIG. 2 shows that the vibration exciter of the internal vibrator 10 is driven by a flexible shaft 17. In addition, the figure shows that the flexible shaft 17 is disposed within a protective tube 16. This unit is after Fig. 2 guided in a sliding guide of a guide tube 18 which is rigid and fixed - here on a clamp connector 20 - is arranged.

Außerdem zeigt die Figur 2, dass der Innenrüttler 10 am Schutzschlauch und an der flexiblen Welle 17 angeordnet ist. Demzufolge werden die Schwingungen im wesentlichen nicht auf das fest stehende Führungsrohr übertragen. Ein letzter Teil vom Schutzschlauch und der flexiblen Welle 17 stehen aus dem Führungsrohr 18 frei vor. Dieser Abschnitt A beträgt nur einen Teil der gesamten Länge der Welle. Diese kann beispielsweise 1 m lang sein, während der Abschnitt A nur eine Länge von z.B. 20 - 50 mm hat. Es ist vorteilhaft, wenn die Länge des Abschnitts A nur ca. ¼ bis ½ des Flaschendurchmessers beträgt.In addition, the shows FIG. 2 in that the internal vibrator 10 is arranged on the protective tube and on the flexible shaft 17. As a result, the vibrations are not substantially transmitted to the fixed guide tube. A last part of the protective tube and the flexible shaft 17 project freely from the guide tube 18. This section A is only part of the total length of the shaft. This may for example be 1 m long, while the section A only has a length of eg 20 - 50 mm. It is advantageous if the length of section A is only about ¼ to ½ of the bottle diameter.

Das Führungsrohr 18 ist mittels dem Klemmverbinder 20 fest mit der Antriebsvorrichtung 12 verbunden.The guide tube 18 is fixedly connected to the drive device 12 by means of the clamping connector 20.

Die Figuren 3 - 6 zeigen den Innenrüttler 10 in vier verschiedenen Stellungen und ferner zeigen diese Figuren, dass durch den Einsatz des Innenrüttlers 10 in Verbindung mit dem Rütteltisch 11 das Volumen des in das Gebinde 15 eingefüllten Produktes verringert wird. Der Produktspiegel 21 ist in den Figuren durch die in strichpunktierten Linien gezeichneten Ellipsen gekennzeichnet. Die Figur 3 zeigt den Innenrüttler 10 in der tiefsten Stellung, d.h. er steht in einem geringstmöglichen Abstand zum Boden des Behältnisses.The Figures 3 - 6 show the internal vibrator 10 in four different positions and further, these figures show that the volume of the filled into the container 15 product is reduced by the use of the internal vibrator 10 in conjunction with the vibrating table 11. The product mirror 21 is indicated in the figures by the ellipses drawn in dotted lines. The FIG. 3 shows the internal vibrator 10 in the lowest position, ie it is at a minimum distance from the bottom of the container.

Mittels der Antriebsvorrichtung 12 wird der Schwingungserreger des Innenrüttlers 10 über die flexible Welle 17 in Schwingungen versetzt. Nach einer durch eine Steuerung vorgegebenen Zeit wird der Antrieb 13 in Betrieb gesetzt, so dass der Innenrüttler 10 einschließlich der Antriebsvorrichtung 12, des Führungsrohres 18 und der flexiblen Welle 17 in vertikaler Richtung nach oben verfahren wird, so dass der der flexiblen Welle 17 zugeordnete Endbereich aus dem Produkt herausragt.By means of the drive device 12, the vibration exciter of the internal vibrator 10 is caused to vibrate via the flexible shaft 17. After a predetermined time by a control of the drive 13 is set in operation, so that the internal vibrator 10 including the drive device 12, the guide tube 18 and the flexible shaft 17 is moved vertically upwards, so that the flexible shaft 17 associated end sticking out of the product.

In dieser Phase wird besonders der obere Bereich des Produktes verdichtet. Die Figur 5 zeigt, dass nach dem Verfahren des Innenrüttlers 10 in die oberste Stellung im Produkt ein Hohlraum 19 verbleibt. Ein Vergleich mit der Figur 6 zeigt jedoch, dass durch den Betrieb des Rütteltisches 11 dieser Hohlraum 19 mit Produkt gefüllt wird, so dass der Produktspiegel 21 noch ein klein wenig abgesenkt wird.In this phase, especially the upper part of the product is compressed. FIG. 5 shows that after the method of the internal vibrator 10 in the uppermost position a cavity 19 remains in the product. A comparison with the FIG. 6 shows, however, that is filled by the operation of the vibrating table 11 of this cavity 19 with product, so that the product level 21 is still lowered a little bit.

Gemäß den Figuren 3 - 6 wird der Innenrüttler 10 in drei verschiedene Stellungen verfahren. Die Anzahl der Stellungen kann durch eine entsprechende Auslegung der Steuerung für den Antrieb 13 verändert, insbesondere erhöht werden. Darüber hinaus könnte der Innenrüttler 10 auch kontinuierlich von der untersten Stellung gemäß der Figur 3 in die obere Stellung gemäß den Figuren 5 und 6 verfahren werden.According to the Figures 3 - 6 the internal vibrator 10 is moved in three different positions. The number of positions can be changed by a corresponding design of the control for the drive 13, in particular increased. In addition, the internal vibrator 10 could also continuously from the lowest position according to the FIG. 3 in the upper position according to the FIGS. 5 and 6 be moved.
