Description

Schlauchbeutelmaschine mit Dosiervorrichtung Tubular bag machine with dosing device
Die Erfindung betrifft eine Schlauchbeutelmaschine mit Dosiervorrich tung, wie sie zur Verpackung von Füllgütern eingesetzt wird. Die The invention relates to a tubular bag machine with Dosiervorrich device, as used for the packaging of products. The
Schlauchbeutelmaschine ist dabei mit einer Längsschweißeinrichtung zur Bildung eines Folienschlauchs ausgestattet. Dieser Folienschlauch wird in der Schlauchbeutelmaschine dann mittels zweier gegeneinander be weglichen und dabei den Folienschlauch quer verschweißender Quersie gelbacken quergesiegelt, so dass kontinuierlich oder intermittierend Schlauchbeutel produziert werden können. Vor dem Verschließen der Schlauchbeutel werden die Schlauchbeutel mittels einer Befüllvorrich- tung mit dem Füllgut befüllt. Nach dem Quersiegeln der Schlauchbeutel werden die einzelnen Schlauchbeutel mittels einer Trenneinrichtung von einander vereinzelt. The tubular bag machine is equipped with a longitudinal welding device for forming a tubular film. This tubular film is then transversely sealed in the tubular bag machine by means of two cross-sealing jaws that move against one another and weld the tubular film transversely, so that tubular bags can be produced continuously or intermittently. Before the tubular bags are closed, the tubular bags are filled with the filling material by means of a filling device. After the tubular bags have been transversely sealed, the individual tubular bags are separated from one another by means of a separating device.
Eine Schlauchbeutelmaschine dieser Art ist beispielsweise aus der EP 0 469 105 bekannt. A tubular bag machine of this type is known from EP 0 469 105, for example.
Bei bekannten Schlauchbeutelmaschinen ist der Befüllvorrichtung eine Dosiervorrichtung vorgeordnet. In der Dosiervorrichtung wird j eweils eine Portion des Füllguts vereinzelt, um den Schlauchbeutel mit der vor gegebenen Menge, beispielsweise einem vorgegebenen Füllgewicht, ei nem vorgegebenen Füllvolumen oder einer vorgegebenen Füllanzahl zu befüllen. Bei den bekannten Schlauchbeutelmaschinen arbeitet die Do siervorrichtung dabei synchron zur Schlauchbeutelmaschine, damit j e weils zum exakt erforderlichen Zeitpunkt die für die Befüllung des Schlauchbeutels notwendige Menge des Füllguts durch die Befüllvorrich- tung eingefüllt werden kann. Diese synchrone Arbeitsweise zwischen Dosiervorrichtung und Schlauchbeutelmaschine führt zunehmend zu Problemen. In known tubular bag machines, a metering device is arranged upstream of the filling device. In the metering device, a portion of the filling material is separated in each case in order to supply the tubular bag with the given amount, for example a given fill weight, a given fill volume or a given number of fillings fill. In the known tubular bag machines, the dosing device works synchronously with the tubular bag machine, so that the filling device can fill in the amount of product required for filling the tubular bag at the exact time required. This synchronous mode of operation between the dosing device and the tubular bag machine leads to increasing problems.
Ein erster Nachteil des Synchronbetriebs zwischen Dosiervorrichtung und Schlauchbeutelmaschine liegt darin, dass j ede kleine Prozessstörung bei der Dosierung in der Dosiervorrichtung zu einem Stillstand oder zu einem Leertakt in der Schlauchbeutelmaschine führt. Insbesondere bei Hochleistungs-Schlauchbeutelmaschinen mit einer Leistung von mehr als 200 Schlauchbeuteln pro Minute kann die Synchronität zwischen A first disadvantage of the synchronous operation between the dosing device and the tubular bag machine is that every small process disturbance during the dosing in the dosing device leads to a standstill or to an idle cycle in the tubular bag machine. Especially with high-performance tubular bag machines with an output of more than 200 tubular bags per minute, the synchronicity between
Schlauchbeutelmaschine und Dosiervorrichtung nur noch sehr aufwendig gewährleistet werden. Ein weiterer Nachteil des Synchronbetriebs zwi schen Schlauchbeutelmaschine und Dosiervorrichtung liegt darin, dass die Dosiervorrichtung dazu gemäß dem vorbekannten Stand der Technik oberhalb der Befüllvorrichtung angeordnet werden muss. Da die Dosier vorrichtung zur Aufrechterhaltung der notwendigen Dosierleistung einen immer größeren Bauraum benötigt, ergibt sich daraus eine immer höhere Raumhöhe, die für die Aufstellung der Schlauchbeutelmaschine mit der darüber angeordneten Dosiervorrichtung erforderlich ist. Tubular bag machine and dosing device can only be guaranteed with great effort. Another disadvantage of the synchronous operation between the tubular bag machine and the dosing device is that the dosing device has to be arranged above the filling device for this purpose according to the known prior art. Since the dosing device requires an ever larger installation space to maintain the necessary dosing capacity, this results in an increasingly higher room height, which is required for the installation of the tubular bag machine with the dosing device arranged above it.
Ausgehend von diesem Stand der Technik ist es deshalb Aufgabe der vorliegenden Erfindung eine neue Schlauchbeutelmaschine vorzuschla gen, die die Nachteile des vorbekannten Stands der Technik vermeidet. Based on this prior art, it is therefore the object of the present invention to propose a new tubular bag machine that avoids the disadvantages of the known prior art.
Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Un teransprüche. Advantageous embodiments of the invention are the subject of the sub-claims Un.
Die erfindungsgemäße Schlauchbeutelmaschine beruht auf dem Grundge danken, dass zwischen der Befüllvorrichtung und der Dosiervorrichtung eine Transfereinrichtung mit mehreren Transferbehältern vorgesehen ist. Dies bedeutet also mit anderen Worten, dass die Dosierung der notwen digen Füllmenge des Füllguts nicht mehr unmittelbar durch Abgabe des Füllguts aus der Dosiervorrichtung in die Befüllvorrichtung der The tubular bag machine according to the invention is based on the basic principle that a transfer device with several transfer containers is provided between the filling device and the dosing device. In other words, this means that the metering of the necessary filling quantity of the filling material is no longer directly by dispensing the filling material from the metering device into the filling device of the
Schlauchbeutelmaschine erfolgt. Stattdessen umfasst die Transfereinrich tung eine Eingabestation, in der die vorgegebenen Füllmengen für jede Befüllung der einzelnen Schlauchbeutel aus der Dosiervorrichtung in j e weils einen Transferbehälter übergeben wird. Anschließend werden die Transferbehälter dann entlang einer Transferstrecke zu einer Abgabesta tion transportiert. In der Abgabestation wird dann der Transferbehälter entleert und das Füllgut aus dem Transferbehälter in die Befüllvorrich tung der Schlauchbeutelmaschine übergeben. Anschließend gelangt der Transferbehälter dann entlang einer Rücktransferstrecke zurück zur Ein gabestation und kann dort erneut aus der Dosiervorrichtung befüllt wer den. Tubular bag machine takes place. Instead, the transfer device comprises an input station in which the specified fill quantities for each filling of the individual tubular bags from the dosing device are transferred to a transfer container in each case. The transfer containers are then transported along a transfer line to a delivery station. The transfer container is then emptied in the delivery station and the filling material is transferred from the transfer container to the filling device of the tubular bag machine. The transfer container is then returned to the input station along a return path, where it can be refilled from the metering device.
Im Ergebnis wird also durch die Transfereinrichtung der Dosierprozess von dem Schlauchbeutelfüllprozess entkoppelt, sodass die Dosiervorrich tung und die Schlauchbeutelmaschine nicht mehr zwingend im Synchron betrieb betrieben werden müssen. Durch diese Entkopplung ist es insbe sondere möglich, dass Störungen in einem der beiden Prozesse nicht un mittelbar eine Störung des anderen Prozesses verursachen. Außerdem wird es durch die Transfereinrichtung möglich die Dosiervorrichtung auch örtlich von der Anordnung an der Schlauchbeutelmaschine unabhän gig zu machen, so dass eine Anordnung der Dosiervorrichtung oberhalb der Befüllvorrichtung der Schlauchbeutelmaschine nicht zwingend erfor derlich ist. As a result, the dosing process is decoupled from the tubular bag filling process by the transfer device, so that the dosing device and the tubular bag machine no longer necessarily have to be operated in synchronous operation. This decoupling makes it possible, in particular, that faults in one of the two processes do not directly cause a fault in the other process. In addition, the transfer device makes it possible to make the dosing device locally independent of the arrangement on the tubular bag machine, so that an arrangement of the dosing device above the filling device of the tubular bag machine is not absolutely necessary.
Durch die Erfindung kann außerdem die Produktfallhöhe reduziert und die Leistung des Prozesses erhöht werden. Auch wird der Produktschutz für bruchempfindliche Produkte erhöht. Es können Transferbehälter mit nicht konstantem Durchmesser eingesetzt werden, um dadurch die Ent leerungsgeschwindigkeit zu erhöhen. Durch die Entkopplung von Dosier- und Beutelbefüllprozess kann die Geschwindigkeit des Befüllprozesses durch optimierte Geschwindigkeitsregelungen und verbesserte Öffnungs verfahren erhöht werden. The invention also enables the product drop height to be reduced and the performance of the process to be increased. Product protection for fragile products is also increased. Transfer containers with a non-constant diameter can be used to increase the emptying speed. By decoupling the dosing and bag filling process, the speed of the filling process can be increased through optimized speed control and improved opening procedures.
Welche Art von Schlauchbeutelmaschine mit der Transfereinrichtung kombiniert wird, ist grundsätzlich beliebig. Besonders große Vorteile bietet die Anordnung der Transfereinrichtung zwischen der Dosiervor richtung und der Schlauchbeutelmaschine in denen Fällen, in denen eine vertikale Schlauchbeutelmaschine zum Einsatz kommt. What kind of tubular bag machine is combined with the transfer device is basically arbitrary. The arrangement of the transfer device between the Dosiervor direction and the tubular bag machine offers particularly great advantages in those cases in which a vertical tubular bag machine is used.
Die konstruktive Ausbildung der Befülleinrichtung ist wiederum grund sätzlich beliebig. Gemäß einer bevorzugten Ausführungsvariante ist die Befülleinrichtung in der Art eines Formatrohrs ausgebildet, wobei der Folienschlauch an der Außenseite des Formatrohrs geführt wird. Durch den Innenquerschnitt des Formatrohrs kann das Füllgut dann unter Schwerkrafteinfluss von oben in den noch offenen Schlauchbeutel einge füllt werden. Für die j eweils zu verwendende Dosiervorrichtung gibt es unterschiedli che Varianten. Grundsätzlich sind alle gravimetrischen oder volumenmet rischen Dosiereinrichtung oder mit einem Zählverfahren arbeitenden Do siereinrichtung einsetzbar. Abhängig davon, in welcher Weise die Dosie rung erfolgt, kann als Dosiervorrichtung entweder eine Waage oder eine Förderschnecke oder ein Zählwerk oder eine Volumendosiereinrichtung zum Einsatz kommen. The structural design of the filling device is in turn basically arbitrary. According to a preferred embodiment variant, the filling device is designed in the manner of a format tube, the film tube being guided on the outside of the format tube. Due to the internal cross-section of the format tube, the filling material can then be filled into the open tubular bag from above under the influence of gravity. There are different variants for the dosing device to be used in each case. In principle, all gravimetric or volumetric metering devices or metering devices that work with a counting method can be used. Depending on the way in which the metering takes place, either a scale or a screw conveyor or a counter or a volume metering device can be used as the metering device.
Im Hinblick auf die Entkopplung des Dosierprozesses von dem Schlauch beutelbefüllprozess ist es besonders vorteilhaft, wenn die Transferein richtung von einer eigenen Transfersteuerung gesteuert wird. Diese Transfersteuerung kann den Übergabeprozess in der Eingabestation unab hängig vom Übergabeprozess in der Abgabestation steuern, so dass eine echte Entkopplung zwischen den beiden Prozessen gewährleistet ist. Im Hinblick auf die Ausregelung kleinerer Prozessstörungen ist es be sonders vorteilhaft, wenn die Transfersteuerung die Fördergeschwindig keit der Transferbehälter entlang der Transferstrecke und/oder entlang der Rücktransferstrecke verändern kann. Durch solche Geschwindigkeits variationen können insbesondere kleinere Verzögerungen im Bereich der Dosierung problemlos ausgeglichen werden, um die rechtzeitige Abgabe der vordosierten Menge des Füllguts in der Abgabestation auch bei Auf treten kleinerer Prozessstörungen zu gewährleisten. With regard to the decoupling of the dosing process from the hose bag filling process, it is particularly advantageous if the transfer device is controlled by its own transfer controller. This transfer control can control the transfer process in the input station independently of the transfer process in the delivery station, so that a real decoupling between the two processes is guaranteed. With regard to the regulation of minor process disruptions, it is particularly advantageous if the transfer control can change the conveying speed of the transfer containers along the transfer path and / or along the return transfer path. Through such speed variations, small delays in the dosing area in particular can be compensated for without any problems in order to ensure the timely delivery of the pre-dosed amount of the filling material in the delivery station even if minor process disruptions occur.
Besonders vorteilhaft ist es, wenn die Transfersteuerung die Förderge schwindigkeit einzelner Transferbehälterunabhängig von der Förderge schwindigkeit der anderen Transferbehälter verändern kann. It is particularly advantageous if the transfer control can change the conveying speed of individual transfer containers independently of the conveying speed of the other transfer containers.
Um auch größere Prozessstörungen und damit verbundene Prozessabwei chungen zwischen dem Dosierprozess und dem Schlauchbeutelbefüllpro zess ausgleichen zu können, kann die Transfereinrichtung mit zumindest einem Puffer ausgestattet werden. In diesem Puffer kann zumindest ein gefüllter oder ungefüllter Transferbehälter zwischengespeichert werden. Kommt es dann zu einer kleineren Prozessstörung, die beispielsweise die rechtzeitige Befüllung eines Transferbehälters verhindert, so kann der im Puffer zwischengespeicherte Transferbehälter entnommen und in die Transferstrecke bzw. die Rücktransferstrecke eingeführt werden. Insbe sondere kann es vorteilhaft sein, vor jeder Abgabestation einen Puffer vorzusehen. The transfer device can be equipped with at least one buffer in order to be able to compensate for larger process disturbances and the associated process deviations between the dosing process and the tubular bag filling process. At least one filled or unfilled transfer container can be temporarily stored in this buffer. If a minor process disruption then occurs, which prevents, for example, the timely filling of a transfer container, the transfer container temporarily stored in the buffer can be removed and introduced into the transfer path or the return transfer path. In particular, it can be advantageous to provide a buffer in front of each delivery station.
In der Grundform der Erfindung wird eine Dosiervorrichtung mittels der Transfereinrichtung mit einer Schlauchbeutelmaschine verbunden. Ge mäß einer bevorzugten Variante ist es j edoch vorgesehen, dass die Trans fereinrichtung zumindest zwei Eingabestationen umfasst, an denen j e weils Füllgut aus einer Dosiervorrichtung an die Transferbehälter über geben werden kann. Auf diese Weise ist es insbesondere möglich, dass die notwendige Dosierleistung auf mehrere Dosiervorrichtungen verteilt wird, so dass beispielsweise eine Hochleistungs-Schlauchbeutelmaschine aus zwei oder mehr Dosiervorrichtungen mit den vordosierten Füllmen gen versorgt werden kann. Die einzelnen Dosiervorrichtungen können dann j eweils eine entsprechend geringere Dosierleistung aufweisen, so dass insbesondere für die Dosierung an Hochleistungs-Schlauchbeutel maschinen keine Hochleistungs-Dosiereinrichtungen eingesetzt werden müssen. In the basic form of the invention, a dosing device is connected to a tubular bag machine by means of the transfer device. According to a preferred variant, however, it is provided that the transfer device comprises at least two input stations, at which filling material can be transferred from a metering device to the transfer container. In this way, it is possible in particular for the necessary metering capacity to be distributed over several metering devices, so that, for example, a high-performance tubular bag machine can be supplied with the pre-metered filling quantities from two or more metering devices. The individual metering devices can then each have a correspondingly lower metering rate, so that no high-performance metering devices have to be used, in particular for metering on high-performance tubular bag machines.
Die Dosierung des Füllguts mittels mehrerer Dosiervorrichtungen und deren Übergabe an zumindest zwei verschiedenen Eingabestationen in die Transferbehälter ist insbesondere auch dann von großem Vorteil, wenn die Schlauchbeutel mit einer Mischbefüllung, beispielsweise einer Nussmischung befüllt werden sollen. Um diese Mischbefüllung zu bil den, können an den verschiedenen Eingabestationen unterschiedliche Füllgüter in die Transferbehälter gefüllt werden, wodurch die einzelnen Transferbehälter dann bei Erreichen der Abgabestation die entsprechend gewünschte Mischung des Füllguts enthalten. Durch die Einzeldosierung der die Mischung ergebenden Teilkomponenten wird außerdem die Do siergenauigkeit der Anteile der Teilkomponenten in der Mischung er höht. The dosing of the filling material by means of several dosing devices and their transfer to at least two different input stations in the transfer container is particularly of great advantage when the tubular bags are to be filled with a mixed filling, for example a mixture of nuts. To bil this mixed filling, different filling goods can be filled into the transfer container at the various input stations, whereby the individual transfer containers then contain the corresponding desired mixture of the filling goods when they reach the delivery station. As a result of the individual metering of the subcomponents resulting in the mixture, the metering accuracy of the proportions of the subcomponents in the mixture is also increased.
Alternativ bzw. additiv zum Einsatz mehrerer Eingabestationen kann die Transfereinrichtung auch mehrere Abgabestationen umfassen. An j eder Abgabestation kann dann das Füllgut bzw. das Mischgut aus den Trans ferbehältern an die Befüllvorrichtung unterschiedlicher Schlauchbeutel maschinen übergeben werden. Durch entsprechende Transfereinrichtun gen können auf diese Weise auch komplexe Transfersysteme gebildet werden, in denen eine Vielzahl möglicherweise auch unterschiedliche Dosiervorrichtungen mit einer Vielzahl unterschiedlicher Schlauchbeu telmaschinen verknüpft werden, so dass ein optimierter Kapazitätsab- gleich zwischen den Dosierkapazitäten und den Abfüllkapazitäten ermög licht wird. As an alternative or in addition to the use of several input stations, the transfer device can also comprise several delivery stations. The filling material or the mixed material can then be transferred from the transfer containers to the filling device of different tubular bag machines at each delivery station. By means of appropriate transfer devices, complex transfer systems can also be formed in this way, in which a large number of possibly different dosing devices can be linked to a large number of different tubular bag machines so that an optimized capacity comparison between the dosing capacities and the filling capacities is made possible.
Verschiedene Ausführungsformen der Erfindung sind in den Zeichnungen schematisiert dargestellt und werden nachfolgend beispielhaft erläutert. Es zeigen: Various embodiments of the invention are shown schematically in the drawings and are explained below by way of example. Show it:

Fig. 4 eine dritte Ausführungsform einer Transfereinrichtung in An sicht von oben. Fig. 1 zeigt eine Schlauchbeutelmaschine 01 zur Herstellung von Fig. 4 shows a third embodiment of a transfer device in view from above. Fig. 1 shows a tubular bag machine 01 for the production of
Schlauchbeuteln 02. Bei der Herstellung der Schlauchbeutel 02 wird zu nächst eine Verpackungsfolie 03 um ein als Befüllvorrichtung 04 dienen des Formatrohr zu einem Schlauch geformt und längsgesiegelt. Der dadurch gebildete Folienschlauch 05 wird mittels Quersiegelbacken 06 quergesiegelt und dadurch am oberen bzw. unteren Ende verschlossen. Der am oberen Ende noch unverschlossene Schlauchbeutel 02 wird wäh rend des Befüllprozesses in der Schlauchbeutelmaschine 01 mit einem Füllgut durch die Befüllvorrichtung 04 befüllt, wozu das Füllgut durch den Innenquerschnitt des Formatrohrs von oben in den noch geöffneten Schlauchbeutel fällt. Tubular bags 02. During the manufacture of tubular bags 02, a packaging film 03 is first formed into a tube around a format tube that serves as a filling device 04 and is longitudinally sealed. The film tube 05 thus formed is transversely sealed by means of transverse sealing jaws 06 and thereby closed at the upper or lower end. The tubular bag 02, which is still unsealed at the upper end, is filled with a filling material through the filling device 04 during the filling process in the tubular bag machine 01, for which the filling material falls through the inner cross section of the format tube from above into the still open tubular bag.
Der Schlauchbeutelmaschine 01 vorgeordnet ist eine Dosiervorrichtung 07, die in der dargestellten Ausführungsform in der Art einer Dosier schnecke 08 mit entsprechendem Antrieb ausgebildet ist. Durch geeigne ten Antrieb der Dosierschnecke 08 kann ein vorgegebenes Füllvolumen des Füllguts aus einem Füllguttrichter 09 herausdosiert werden. Upstream of the tubular bag machine 01 is a metering device 07 which, in the embodiment shown, is designed in the manner of a metering screw 08 with a corresponding drive. A predetermined filling volume of the filling material can be dosed out of a filling material funnel 09 by suitable drive of the metering screw 08.
Zwischen der Schlauchbeutelmaschine 01 und der Dosiervorrichtung 07 ist eine Transfereinrichtung 10 angeordnet. Die Transfereinrichtung 10 umfasst eine Eingabestation 1 1 und eine Abgabestation 12. In der Einga bestation 1 1 können Transferbehälter 13 aus der Dosiervorrichtung 07 mit der vordosierten Menge des Füllguts befüllt werden. Anschließend werden die Transferbehälter 13 entlang einer Transferstrecke 14 zur Ab gabestation 12 transportiert. In der Abgabestation 12 erfolgt ein Entlee ren der Transferbehälter 13 , so dass die vordosierte Menge des Füllguts durch die Befüllvorrichtung 04 von oben in die geöffneten Schlauchbeu tel fällt. Die Befüllung der Transferbehälter 13 in der Eingabestation 1 1 erfolgt dabei unabhängig von der Entleerung der Transferbehälter 13 in der Abgabestation, so dass eine Synchronität zwischen dem Dosierpro zess in der Dosiervorrichtung 07 und dem Schlauchbeutelbefüllprozess in der Schlauchbeutelmaschine 01 nicht mehr erforderlich ist. Durch Varia tion der Fördergeschwindigkeit der Transferbehälter 13 entlang der Transferstrecke 14 können Synchronitätsabweichungen zwischen den bei den Prozessen problemlos ausgeglichen werden. A transfer device 10 is arranged between the tubular bag machine 01 and the metering device 07. The transfer device 10 comprises an input station 11 and a dispensing station 12. In the input station 11, transfer containers 13 from the dosing device 07 can be filled with the pre-dosed amount of the filling material. The transfer containers 13 are then transported along a transfer path 14 to the transfer station 12. In the dispensing station 12, the transfer container 13 is emptied so that the pre-metered amount of the filling material falls through the filling device 04 from above into the opened tubular bag. The filling of the transfer container 13 in the input station 11 takes place independently of the emptying of the transfer container 13 in the delivery station, so that synchronization between the dosing process in the dosing device 07 and the tubular bag filling process in the tubular bag machine 01 is no longer necessary. By varying the conveying speed of the transfer containers 13 along the transfer path 14, deviations in synchronicity between the processes can be easily compensated for.
Fig. 2 zeigt die Transfereinrichtung 10 mit der Eingabestation 1 1 und der Abgabestation 12 in schematisierter Ansicht von oben. Wie aus Fig. 2 er sichtlich, werden die Transferbehälter 13 nach der Entleerung in der Ab gabestation 12 entlang einer Rücktransferstrecke 15 zurück zur Eingabe station 1 1 transportiert, so dass sie dort erneut mit einer vordosierten Menge des Füllguts befüllt werden können. Um auch größere Synchroni tätsverschiebungen zwischen der Befüllung der Transferbehälter in der Eingabestation 1 1 und der Entleerung der Transferbehälter 13 in der Ab gabestation 12 ausgleichen zu können, enthält die Transferstrecke 14 au ßerdem einen Puffer 16, in dem mehrere Transferbehälter 13 zwischenge speichert werden können. Zur Befüllung bzw. zur Entnahme der Trans ferbehälter 13 im Puffer 16 dienen Weichenelemente 17. Fig. 2 shows the transfer device 10 with the input station 1 1 and the delivery station 12 in a schematic view from above. As can be seen from Fig. 2, the transfer containers 13 are transported after emptying in the Ab transfer station 12 along a return path 15 back to the input station 11, so that they can be filled there again with a pre-dosed amount of the product. In order to be able to compensate for larger synchroni ity shifts between the filling of the transfer container in the input station 11 and the emptying of the transfer container 13 in the output station 12, the transfer line 14 also contains a buffer 16 in which several transfer containers 13 can be temporarily stored. Switch elements 17 are used to fill or remove the transfer containers 13 in the buffer 16.
Fig. 3 zeigt eine alternative Ausführungsform 18 einer Transfereinrich tung. Der grundsätzliche Aufbau der Transfereinrichtung 18 entspricht dem Aufbau der Transfereinrichtung 10, wobei die Transfereinrichtung 18 eine zusätzliche Eingabestation 19 umfasst. An der zusätzlichen Ein gabestation 19 können die Transferbehälter 13 unter Verwendung einer weiteren Dosiervorrichtung wiederum mit vordosierten Füllmengen eines Füllguts befüllt werden. Dabei ist es denkbar, dass in den Eingabestatio- nen 1 1 und 19 j eweils unterschiedliche Transferbehälter mit Füllgut be füllt werden, um auf diese Weise die erforderliche Dosierkapazität durch Verwendung zweier Dosiervorrichtungen zu erhöhen. Alternativ dazu können die Transferbehälter 13 in den Eingabestationen 1 1 und 19 auch j eweils mit unterschiedlichen Füllgütern befüllt werden, so dass j eder Transferbehälter nach Verlassen der Eingabestation 19 eine vordosierte Mischung von Füllgütern enthält. Fig. 3 shows an alternative embodiment 18 of a transfer device. The basic structure of the transfer device 18 corresponds to the structure of the transfer device 10, the transfer device 18 comprises an additional input station 19. At the additional input station 19, the transfer container 13 can in turn be filled with pre-dosed quantities of a product using a further metering device. It is conceivable that different transfer containers are filled with filling material in input stations 11 and 19 in order to increase the required dosing capacity by using two dosing devices. As an alternative to this, the transfer containers 13 in the input stations 11 and 19 can also be filled with different filling materials in each case, so that each transfer container contains a pre-dosed mixture of filling materials after leaving the input station 19.
Fig. 4 zeigt eine dritte Ausführungsform 20 einer Transfereinrichtung. Die Transfereinrichtung 20 unterscheidet sich von der Transfereinrich tung 18 durch den zusätzlichen Einsatz einer weiteren Abgabestation 21 . Im Ergebnis können also mittels der Transfereinrichtung 20 die Transfer behälter 13 zum einen in den Eingabestationen 1 1 und 19 unter Verwen dung unterschiedlicher Dosiervorrichtungen mit Füllgut befüllt werden und die Füllgüter aus den Transferbehältern 13 dann an den Abgabestati onen 12 und 21 an zwei verschiedene Schlauchbeutelmaschinen abgege- ben werden. Soweit die Transfereinrichtungen weitere Eingabestationen bzw. Abgabestationen umfassen, können komplexe Transfersysteme, ge bildet aus einer Vielzahl von Dosiervorrichtungen und einer Vielzahl von Schlauchbeutelmaschinen, realisiert werden. 4 shows a third embodiment 20 of a transfer device. The transfer device 20 differs from the transfer device 18 by the additional use of a further delivery station 21. As a result, the transfer device 20, the transfer container 13 on the one hand in the input stations 1 1 and 19 using different metering devices are filled with filling material and the filling materials from the transfer containers 13 are then delivered to the Abgabestati onen 12 and 21 to two different tubular bag machines - be practiced. As far as the transfer devices comprise further input stations or delivery stations, complex transfer systems, formed from a multitude of metering devices and a multitude of tubular bag machines, can be implemented.
