Description

Die Erfindung betrifft eine Transfereinrichtung zur Anordnung zwischen einer Dosiervorrichtung und der Befüllvorrichtung einer Schlauchbeutelmaschine nach dem Oberbegriff des Anspruchs 1. Die Schlauchbeutelmaschine kann dabei beispielsweise mit einer Längsschweißeinrichtung zur Bildung eines Folienschlauchs ausgestattet sein. Dieser Folienschlauch wird in der Schlauchbeutelmaschine dann mittels zweier gegeneinander beweglichen und dabei den Folienschlauch quer verschweißenden Quersiegelbacken quergesiegelt, so dass kontinuierlich oder intermittierend Schlauchbeutel produziert werden können. Vor dem Verschließen der Schlauchbeutel werden die Schlauchbeutel mittels einer Befüllvorrichtung mit Füllgut befüllt. Nach dem Quersiegeln der Schlauchbeutel werden die einzelnen Schlauchbeutel mittels einer Trenneinrichtung voneinander vereinzelt.The invention relates to a transfer device for arrangement between a dosing device and the filling device of a tubular bag machine according to the preamble of claim 1. The tubular bag machine can be equipped, for example, with a longitudinal welding device for forming a film tube. This film tube is then sealed transversely in the tubular bag machine by means of two transverse sealing jaws that move against each other and weld the film tube transversely, so that tubular bags can be produced continuously or intermittently. Before the tubular bags are closed, the tubular bags are filled with 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 04 69 105 bekannt.A form fill and seal machine of this type is, for example, from the EP0469105 known.

Bei bekannten Schlauchbeutelmaschinen ist der Befüllvorrichtung eine Dosiervorrichtung vorgeordnet. In der Dosiervorrichtung wird jeweils eine Portion des Füllguts vereinzelt, um den Schlauchbeutel mit der vorgegebenen Menge, beispielsweise einem vorgegebenen Füllgewicht, einem vorgegebenen Füllvolumen oder einer vorgegebenen Füllanzahl zu befüllen. Bei den bekannten Schlauchbeutelmaschinen arbeitet die Dosiervorrichtung dabei synchron zur Schlauchbeutelmaschine, damit jeweils zum exakt erforderlichen Zeitpunkt die für die Befüllung des Schlauchbeutels notwendige Menge des Füllguts durch die Befüllvorrichtung eingefüllt werden kann. Diese synchrone Arbeitsweise zwischen Dosiervorrichtung und Schlauchbeutelmaschine führt zunehmend zu Problemen.In known form fill and seal machines, a dosing device is arranged in front of the filling device. In the dosing device, a portion of the filling material is separated in order to fill the tubular bag with the specified quantity, for example a specified filling weight, a specified filling volume or a specified filling number. In the known tubular bag machines, the dosing device works synchronously with the tubular bag machine so that the amount of filling material required to fill the tubular bag can be filled through the filling device at exactly the right time. This synchronous operation between the dosing device and the tubular bag machine is increasingly leading to problems.

Ein erster Nachteil des Synchronbetriebs zwischen Dosiervorrichtung und Schlauchbeutelmaschine liegt darin, dass jede 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 Schlauchbeutelmaschine und Dosiervorrichtung nur noch sehr aufwendig gewährleistet werden. Eine weitere Leistungssteigerung bei der Abpackung des Füllguts unter Verwendung von Hochleistungs-Schlauchbeutelmaschinen ist deshalb mit den bekannten Systemen nicht mehr bzw. nur unter Inkaufnahme eines sehr hohen Aufwands möglich.A first disadvantage of synchronous operation between the dosing device and the tubular bag machine is that every small process disturbance during dosing in the dosing device leads to a standstill or an idle cycle in the tubular bag machine. In particular with high-performance tubular bag machines with an output of more than 200 tubular bags per minute, the synchronicity between the tubular bag machine and the dosing device can only be guaranteed with great effort. A further increase in performance when packaging the filling material using high-performance tubular bag machines is therefore no longer possible with the known systems or only at the expense of very high costs.

Die DE 10 2014 219448 A1 (D1) beschreibt eine Transfereinrichtung zur Anordnung zwischen einer Dosiervorrichtung und einer Befüllvorrichtung einer Schlauchbeutelmaschine, bei der die Eigenschaften des Füllguts ausgenutzt werden, um in Folge der Massenträgheit und der Schwarmbildung des Füllguts das Füllgut von einem Transferbehälter in eine Befüllvorrichtung zu überführen. Nachteiligerweise ist eine derartige Transfereinrichtung auf geeignete Füllgüter beschränkt und die Prozesszeit zur Übergabe des Füllguts sowie die Packleistung der Schlauchbeutelmaschine von der Massenträgheit und der Schwarmbildung des Füllguts abhängig.The EN 10 2014 219448 A1 (D1) describes a transfer device for arrangement between a dosing device and a filling device of a tubular bag machine, in which the properties of the filling material are exploited in order to transfer the filling material from a transfer container into a filling device as a result of the mass inertia and the swarming of the filling material. Disadvantageously, such a transfer device is limited to suitable filling materials and the process time for transferring the filling material as well as the packing performance of the tubular bag machine depend on the mass inertia and the swarming of the filling material.

Ausgehend von diesem Stand der Technik ist es deshalb Aufgabe der vorliegenden Erfindung eine Transfereinrichtung zur Anordnung zwischen einer Dosiervorrichtung und der Befüllvorrichtung einer Schlauchbeutelmaschine vorzuschlagen, mit der die Packleistung der Schlauchbeutelmaschine mit relativ geringem Aufwand erhöht werden kann. Weiter ist es Aufgabe der vorliegenden Erfindung ein Verfahren zum Betrieb einer solchen Transfereinrichtung vorzuschlagen.Based on this prior art, it is therefore the object of the present invention to propose a transfer device for arrangement between a dosing device and the filling device of a tubular bag machine, with which the packaging performance of the tubular bag machine can be increased with relatively little effort. It is also the object of the present invention to propose a method for operating such a transfer device.

Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.

Die erfindungsgemäße Transfereinrichtung umfasst eine Eingabestation, eine Ausgabestation und mehrere Transferbehälter. Die jeweils vorgegebene Füllmenge des Füllguts zur Befüllung in einen Schlauchbeutel wird in der Eingabestation aus der Dosiervorrichtung an die jeweils in der Eingabestation befindlichen Transferbehälter übergeben. Anschließend werden die Transferbehälter entlang einer Transferstrecke zu der Abgabestation transportiert. In der Abgabestation wiederum werden die Transferbehälter geleert, und das in den Transferbehältern transferierte Füllgut in die Befüllvorrichtung der Schlauchbeutelmaschine übergeben. Zuletzt gelangen die Transferbehälter entlang der Rücktransferstrecke zurück zur Eingabestation und werden dort erneut aus der Dosiervorrichtung mit Füllgut befüllt.The transfer device according to the invention comprises an input station, an output station and several transfer containers. The respective predetermined filling quantity of the filling material for filling into a tubular bag is transferred from the dosing device in the input station to the transfer containers located in the input station. The transfer containers are then transported along a transfer path to the delivery station. In the delivery station, the transfer containers are emptied and the filling material transferred in the transfer containers is transferred to the filling device of the tubular bag machine. Finally, the transfer containers return along the return transfer path to the input station and are filled again with filling material from the dosing device.

Um die Leistungsfähigkeit der Transfereinrichtung bei der Übergabe des Füllguts an die Befüllvorrichtung der Schlauchbeutelmaschine zu erhöhen, ist erfindungsgemäß eine Transfersteuerung zur Steuerung der Transfereinrichtung bei Übergabe des Füllguts an die Schlauchbeutelmaschine gesteuert. Die Transfersteuerung ist dabei so eingerichtet, dass der Übergabeprozess in der Ausgabestation entweder a) in Abhängigkeit von der Position des Transferbehälters relativ zur Befüllvorrichtung und/oder b) in Abhängigkeit von der Geschwindigkeit des Transferbehälters gesteuert werden kann. In Abkehr der bisher üblichen Übergabeprozesse bedeutet dies, dass die Übergabe des Füllguts aus dem Transferbehälter nicht erst nach dem vollständigen Stillstand des Transferbehälters über der Befüllvorrichtung beginnt. Stattdessen kann der Übergabeprozess bereits vor dem vollständigen Stillstand des Transferbehälters über der Befüllvorrichtung entweder in Abhängigkeit von der Position des Transferbehälters und/oder in Abhängigkeit der Geschwindigkeit des Transferbehälters eingeleitet werden.In order to increase the performance of the transfer device when transferring the filling material to the filling device of the tubular bag machine, a transfer control is provided according to the invention to control the transfer device when transferring the filling material to the tubular bag machine. The transfer control is set up in such a way that the transfer process in the output station can be controlled either a) depending on the position of the transfer container relative to the filling device and/or b) depending on the speed of the transfer container. In contrast to the previously usual transfer processes, this means that the transfer of the filling material from the transfer container does not begin until the transfer container has come to a complete standstill above the filling device. Instead, the transfer process can be initiated before the transfer container has come to a complete standstill above the filling device, either depending on the position of the transfer container and/or depending on the speed of the transfer container.

Erfindungsgemäß ist es vorgesehen, dass die Transferbehälter jeweils einen Verschluss aufweisen, der zwischen einer Schließstellung und einer Öffnungsstellung verstellt werden kann. In der Schließstellung des Verschlusses ist der Transferbehälter geschlossen und das Füllgut im Transferbehälter gespeichert. Wird der Verschluss dann in die Öffnungsstellung verstellt, öffnet sich der Transferbehälter dadurch, so dass das Füllgut unter Schwerkrafteinfluss aus der Öffnung des Transferbehälters in die Befüllvorrichtung übergeben wird. Gemäß dieser bevorzugten Vorrichtungsvariante ist es vorgesehen, dass der Verschluss des Transferbehälters in Abhängigkeit von der Position des Transferbehälters relativ zur Befüllvorrichtung und/oder in Abhängigkeit von der Geschwindigkeit des Transferbehälters geöffnet werden kann. Im Ergebnis kann dadurch erreicht werden, dass der Verschluss des Transferbehälters bereits vor dem vollständigen Stillstand des Transferbehälters oberhalb der Befüllvorrichtung geöffnet wird, so dass das Füllgut bereits unter Schwerkrafteinfluss nach unten rutscht, bevor der Transferbehälter zum vollständigen Stillstand in der Abgabestation gekommen ist. Durch diesen vorzeitigen Beginn der Verstellung des Verschlusses aus der Schließstellung in die Öffnungsstellung kann Prozesszeit, die für die Übergabe des Füllguts aus dem Transferbehälter in die Befüllvorrichtung der Schlauchbeutelmaschine erforderlich ist, eingespart werden, um auf diese Weise eine höhere Packleistung der Schlauchbeutelmaschine durch Erhöhung des Arbeitstakts zu realisieren.According to the invention, it is provided that the transfer containers each have a closure that can be adjusted between a closed position and an open position. In the closed position of the closure, the transfer container is closed and the filling material is stored in the transfer container. If the closure is then adjusted to the open position, the transfer container opens so that the filling material is transferred from the opening of the transfer container into the filling device under the influence of gravity. According to this preferred device variant, it is provided that the closure of the transfer container can be opened depending on the position of the transfer container relative to the filling device and/or depending on the speed of the transfer container. As a result, the closure of the transfer container can be opened before the transfer container has come to a complete standstill above the filling device, so that the filling material already slides downwards under the influence of gravity before the transfer container has come to a complete standstill in the delivery station. By starting the adjustment of the closure from the closed position to the open position at an early stage, the process time required for transferring the filling material from the transfer container to the filling device of the flow-wrapping machine can be saved, thus achieving a higher packing performance of the flow-wrapping machine by increasing the work cycle.

Im Hinblick auf eine weitere Steigerung der Packleistung ist es vorteilhaft, wenn das Transportvolumen der Transferbehälter, in welchen das Füllgut aufgenommen ist, einen Querschnitt aufweist, der sich von oben nach unten vergrößert. Ist der Transferbehälter beispielweise mit einem Verschluss ausgestattet, durch den eine Öffnung im Transferbehälter verschlossen wird, bewirkt das Öffnen dieses Verschlusses, dass das gesamte im Transportvolumen vorhandene Füllgut gleichzeitig vertikal nach unten rutscht. Die durch Haftreibung bewirkte Bremswirkung der Wandungen des Transferbehälters zum Transportvolumen entfällt weitgehend durch den sich nach unten erweiternden Querschnitt des Transportvolumens.With a view to further increasing the packing performance, it is advantageous if the transport volume of the transfer containers in which the The cross-section of the transfer container is such that it increases from top to bottom. If, for example, the transfer container is equipped with a closure that closes an opening in the transfer container, opening this closure causes the entire contents of the transport volume to slide vertically downwards at the same time. The braking effect of the walls of the transfer container on the transport volume caused by static friction is largely eliminated by the cross-section of the transport volume expanding downwards.

Im Hinblick auf die Erhöhung der Packleistung der Schlauchbeutelmaschine ist es weiterhin vorteilhaft, wenn der Querschnitt des Transportvolumens im Bereich des Verschlusses des Transferbehälters im Wesentlichen mit dem Querschnitt am Eintritt der Befüllvorrichtung der Schlauchbeutelmaschine übereinstimmt. Da das Füllgut im Transportvolumen der Transferbehälter bereits vorformatiert ist, kann eine Formatierung des Füllguts am Eingang der Befüllvorrichtung, wie sie ansonsten mit entsprechenden Trichtern bewirkt werden muss, entfallen. Stattdessen rutscht das Füllgut aus dem Querschnitt des Transportvolumens im Transferbehälter im Wesentlichen kongruent in den darunterliegenden Querschnitt der Befüllvorrichtung. Um die Transfereinrichtung variabel auf verschiedene Transferaufgaben, beispielsweise beim Transfer unterschiedlicher Füllgüter, einstellen zu können, ist es besonders vorteilhaft, wenn der Querschnitt des Transportvolumens in den Transferbehältern veränderbar ist. Dadurch kann insbesondere erreicht werden, dass die gleichen Transferbehälter zur Beschickung von Befüllvorrichtungen mit unterschiedlichem Querschnitt verwendet werden können. Um eine weitere Leistungssteigerung beim Befüllen der Schlauchbeutel zu erreichen, ist es vorteilhaft, wenn an den Transferbehältern und/oder an der Ausgabestation eine Ausstoßeinrichtung vorgesehen ist, mit der das Füllgut aus dem Transportvolumen des Transportbehälters ausgestoßen werden kann. Durch solch eine Ausstoßeinrichtung kann insbesondere auch eine Unterstützung der Schwerkraft beim Entleeren der Transferbehälter erreicht werden.With a view to increasing the packaging performance of the tubular bag machine, it is also advantageous if the cross-section of the transport volume in the area of the closure of the transfer container essentially corresponds to the cross-section at the inlet of the filling device of the tubular bag machine. Since the filling material in the transport volume of the transfer container is already pre-formatted, formatting of the filling material at the inlet of the filling device, as would otherwise have to be done with appropriate funnels, can be omitted. Instead, the filling material slides essentially congruently from the cross-section of the transport volume in the transfer container into the cross-section of the filling device below. In order to be able to variably adjust the transfer device to different transfer tasks, for example when transferring different filling materials, it is particularly advantageous if the cross-section of the transport volume in the transfer containers can be changed. This makes it possible in particular to use the same transfer containers to feed filling devices with different cross-sections. In order to achieve a further increase in performance when filling the tubular bags, it is advantageous if an ejection device is provided on the transfer containers and/or on the output station, with which the filling material can be ejected from the transport volume of the transport container. Such an ejection device can in particular Gravity can also be used to assist in emptying the transfer containers.

In welcher Bauart die Ausstoßeinrichtung ausgebildet ist, ist grundsätzlich beliebig. So sind insbesondere auch mechanisch arbeitende Ausstoßeinrichtungen denkbar. Im Hinblick auf die Flexibilität der Ausstoßeinrichtung ist es besonders vorteilhaft, wenn diese in der Art einer Druckluftdüse ausgebildet ist. Durch die an der Druckluftdüse ausgestoßene Druckluft kann das Füllgut aus dem Transferbehälter herausgedrückt und in die Befüllvorrichtung der Schlauchbeutelmaschine geblasen werden.The design of the ejection device is basically arbitrary. Mechanically operated ejection devices are also conceivable. In terms of the flexibility of the ejection device, it is particularly advantageous if it is designed in the form of a compressed air nozzle. The compressed air emitted from the compressed air nozzle can push the filling material out of the transfer container and blow it into the filling device of the tubular bag machine.

Die Bauart der Befülleinrichtung, an der das Füllgut aus der Transfereinrichtung übergeben wird, ist ebenfalls grundsätzlich beliebig. Gemäß einer bevorzugten Variante ist die Befülleinrichtung in der Art eines Formatrohrs ausgebildet, wobei der Folienschlauch zur Bildung der Schlauchbeutel an der Außenseite des Formatrohrs geführt wird.The design of the filling device to which the filling material is transferred from the transfer device is also basically arbitrary. According to a preferred variant, the filling device is designed in the form of a format tube, with the film tube being guided on the outside of the format tube to form the tubular bag.

Als Dosiervorrichtungen zur Dosierung des Füllguts in die Transferbehälter der Transfereinrichtung sind verschiedenste Vorrichtungen denkbar. Bevorzugt kann die Dosiervorrichtung in der Art einer Waage oder einer Förderschnecke oder eines Zählwerks oder einer Volumendosiereinrichtung ausgebildet sein.A wide variety of devices are conceivable as dosing devices for dosing the filling material into the transfer containers of the transfer device. The dosing device can preferably be designed in the form of a scale or a conveyor screw or a counter or a volume dosing device.

Um der Transfersteuerung eine Steuerung des Übergabeprozesses in Abhängigkeit von der Position des Transferbehälters bzw. in Abhängigkeit von der Geschwindigkeit des Transferbehälters zu ermöglichen, ist es besonders vorteilhaft, wenn eine entsprechende Sensorik zur Messung der Position bzw. der Geschwindigkeit der Transferbehälter vorhanden ist. Mit dieser Sensorik können die Ist-Werte der Fördergeschwindigkeit bzw. der Position der Transferbehälter gemessen und an die Transfersteuerung übertragen werden.In order to enable the transfer control to control the transfer process depending on the position of the transfer container or depending on the speed of the transfer container, it is particularly advantageous if appropriate sensors are available to measure the position or speed of the transfer containers. With this sensor, the actual values of the conveying speed or the position of the transfer containers can be measured and transmitted to the transfer control.

Beim Betrieb der erfindungsgemäßen Transfereinrichtung ist eine Koordination der Bewegungsabläufe in der Transfereinrichtung mit den Bewegungsabläufen in der Schlauchbeutelmaschine von größter Bedeutung, da die Bewegungskinematik insbesondere bei hohen Taktzahlen hoch exakt aufeinander abgestimmt werden muss. Um dies in einfacher Weise zu ermöglichen, ist es besonders vorteilhaft, wenn die Transfersteuerung eine Datenschnittstelle aufweist, mit der die Transfersteuerung Daten mit der Steuerung der Schlauchbeutelmaschine austauschen kann. Auf diese Weis ist eine Synchronisation zwischen Transfersteuerung und der Steuerung der Schlauchbeutelmaschine problemlos realisierbar.When operating the transfer device according to the invention, coordination of the movement sequences in the transfer device with the Movement sequences in the tubular bag machine are of the utmost importance, as the movement kinematics must be coordinated with one another with great precision, particularly at high cycle rates. In order to make this possible in a simple manner, it is particularly advantageous if the transfer control has a data interface with which the transfer control can exchange data with the control of the tubular bag machine. In this way, synchronization between the transfer control and the control of the tubular bag machine can be easily achieved.

Das erfindungsgemäße Verfahren ist dadurch charakterisiert, dass das Füllgut zumindest teilweise während der Transportbewegung des Transferbehälters in der Abgabestation in die Befüllvorrichtung der Schlauchbeutelmaschine übergeben wird. Ein vollständiger Stillstand der Transferbehälter bei Übergabe des Füllguts ist somit nicht mehr erforderlich, was eine erhebliche Leistungssteigerung bei der Übergabe des Füllguts ermöglicht. Weiter ist es dabei vorgesehen, dass der Verschluss eines Transferbehälters vor dem vollständigen Stillstand in der Abgabestation geöffnet wird, um den Übergabeprozess durch die Verstellung des Verschlusses aus seiner Schließstellung in die Öffnungsstellung bereits vor dem Stillstand der Transferbehälter zu beginnen.The method according to the invention is characterized in that the filling material is at least partially transferred to the filling device of the tubular bag machine during the transport movement of the transfer container in the delivery station. A complete standstill of the transfer container when the filling material is transferred is therefore no longer necessary, which enables a significant increase in performance when transferring the filling material. It is also provided that the closure of a transfer container is opened before it comes to a complete standstill in the delivery station in order to start the transfer process by moving the closure from its closed position to the open position before the transfer container comes to a standstill.

Fig. 1 zeigt eine Schlauchbeutelmaschine 01 zur Herstellung von Schlauchbeuteln 02. Bei der Herstellung der Schlauchbeutel 02 wird zunächst eine Verpackungsfolie 03 um ein als Befüllvorrichtung 04 dienendes 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 während 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. Fig.1 shows a tubular bag machine 01 for producing tubular bags 02. During the production of the tubular bags 02, a packaging film 03 is first formed into a tube around a format tube serving as a filling device 04 and sealed lengthwise. The film tube 05 thus formed is sealed crosswise using cross-sealing jaws 06 and thereby closed at the upper and lower ends. The tubular bag 02, which is still unsealed at the upper end, is filled with a filling material by the filling device 04 during the filling process in the tubular bag machine 01, whereby the filling material falls from above through the inner cross section of the format tube into the still open tubular bag.

Der Schlauchbeutelmaschine 01 vorgeordnet ist eine Dosiervorrichtung 07, die in der dargestellten Ausführungsform in der Art einer Dosierschnecke 08 mit entsprechendem Antrieb ausgebildet ist. Durch geeigneten Antrieb der Dosierschnecke 08 kann ein vorgegebenes Füllvolumen des Füllguts aus einem Füllguttrichter 09 herausdosiert werden.A dosing device 07 is arranged upstream of the tubular bag machine 01 and, in the embodiment shown, is designed in the form of a dosing screw 08 with a corresponding drive. By suitably driving the dosing screw 08, a predetermined filling volume of the filling material can be dosed out of a filling material hopper 09.

Zwischen der Schlauchbeutelmaschine 01 und der Dosiervorrichtung 07 ist eine Transfereinrichtung 10 angeordnet. Die Transfereinrichtung 10 umfasst eine Eingabestation 11 und eine Abgabestation 12. In der Eingabestation 11 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 Abgabestation 12 transportiert. In der Abgabestation 12 erfolgt ein Entleeren der Transferbehälter 13, so dass die vordosierte Menge des Füllguts durch die Befüllvorrichtung 04 von oben in die geöffneten Schlauchbeutel fällt. Die Befüllung der Transferbehälter 13 in der Eingabestation 11 erfolgt dabei unabhängig von der Entleerung der Transferbehälter 13 in der Abgabestation, so dass eine Synchronität zwischen dem Dosierprozess in der Dosiervorrichtung 07 und dem Schlauchbeutelbefüllprozess in der Schlauchbeutelmaschine 01 nicht mehr erforderlich ist. Durch Variation der Fördergeschwindigkeit der Transferbehälter 13 entlang der Transferstrecke 14 können Synchronitätsabweichungen zwischen den beiden Prozessen problemlos ausgeglichen werden.A transfer device 10 is arranged between the tubular bag machine 01 and the dosing device 07. The transfer device 10 comprises an input station 11 and a delivery 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 delivery station 12. In the delivery station 12, the transfer containers 13 are emptied so that the pre-dosed amount of the filling material falls from above into the opened tubular bags through the filling device 04. The transfer containers 13 are filled in the input station 11 independently of the emptying of the transfer containers 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, synchronicity deviations between the two processes can be easily compensated.

Fig. 2 zeigt die Transfereinrichtung 10 mit der Eingabestation 11 und der Abgabestation 12 in schematisierter Ansicht von oben. Wie aus Fig. 2 ersichtlich, werden die Transferbehälter 13 nach der Entleerung in der Abgabestation 12 entlang einer Rücktransferstrecke 15 zurück zur Eingabestation 11 transportiert, so dass sie dort erneut mit einer vordosierten Menge des Füllguts befüllt werden können. Um auch größere Synchronitätsverschiebungen zwischen der Befüllung der Transferbehälter in der Eingabestation 11 und der Entleerung der Transferbehälter 13 in der Abgabestation 12 ausgleichen zu können, enthält die Transferstrecke 14 außerdem einen Puffer 16, in dem mehrere Transferbehälter 13 zwischengespeichert werden können. Zur Befüllung bzw. zur Entnahme der Transferbehälter 13 im Puffer 16 dienen Weichenelemente 17. Fig.2 shows the transfer device 10 with the input station 11 and the output station 12 in a schematic view from above. As can be seen from Fig.2 As can be seen, the transfer containers 13 are transported along a return transfer path 15 back to the input station 11 after emptying in the delivery station 12, so that they can be filled there again with a pre-dosed amount of the filling material. In order to also avoid larger synchronization shifts between the filling of the transfer containers in the input station 11 and the emptying of the transfer containers 13 In order to be able to compensate for the load in the delivery station 12, the transfer section 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 Transfereinrichtung. Der grundsätzliche Aufbau der Transfereinrichtung 18 entspricht dem Aufbau der Transfereinrichtung 10, wobei die Transfereinrichtung 18 eine zusätzliche Eingabestation 19 umfasst. An der zusätzlichen Eingabestation 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 Eingabestationen 11 und 19 jeweils unterschiedliche Transferbehälter mit Füllgut befüllt werden, um auf diese Weise die erforderliche Dosierkapazität durch Verwendung zweier Dosiervorrichtungen zu erhöhen. Alternativ dazu können die Transferbehälter 13 in den Eingabestationen 11 und 19 auch jeweils mit unterschiedlichen Füllgütern befüllt werden, so dass jeder 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, wherein the transfer device 18 comprises an additional input station 19. At the additional input station 19, the transfer containers 13 can again be filled with pre-dosed quantities of a filling material using a further dosing device. It is conceivable that different transfer containers are filled with filling material in the input stations 11 and 19 in order to increase the required dosing capacity by using two dosing devices. Alternatively, the transfer containers 13 in the input stations 11 and 19 can also be filled with different filling materials 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 Transfereinrichtung 18 durch den zusätzlichen Einsatz einer weiteren Abgabestation 21. Im Ergebnis können also mittels der Transfereinrichtung 20 die Transferbehälter 13 zum einen in den Eingabestationen 11 und 19 unter Verwendung unterschiedlicher Dosiervorrichtungen mit Füllgut befüllt werden und die Füllgüter aus den Transferbehältern 13 dann an den Abgabestationen 12 und 21 an zwei verschiedene Schlauchbeutelmaschinen abgegeben werden. Soweit die Transfereinrichtungen weitere Eingabestationen bzw. Abgabestationen umfassen, können komplexe Transfersysteme, gebildet aus einer Vielzahl von Dosiervorrichtungen und einer Vielzahl von Schlauchbeutelmaschinen, realisiert werden. Fig.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 can be used to fill the transfer containers 13 with filling material in the input stations 11 and 19 using different dosing devices and the filling materials from the transfer containers 13 can then be delivered to two different tubular bag machines at the delivery stations 12 and 21. If the transfer devices include further input stations or delivery stations, complex transfer systems formed from a large number of dosing devices and a large number of tubular bag machines can be implemented.

Fig. 5 zeigt den Transferbehälter 13 zur Verwendung in den Transfereinrichtungen 10, 18 und 20 im Querschnitt. Der Boden des Transferbehälters 13 wird von einem Verschluss 22 gebildet, der schwenkbar am Transferbehälter 13 gelagert ist und mit einer in Fig. 5 nicht dargestellten Antriebseinrichtung zwischen der in Fig. 5 dargestellten Schließstellung und der in Fig. 6 dargestellten Öffnungsstellung motorisch verstellt werden kann. In Fig. 5 befindet sich der Verschluss 22 in seiner Schließstellung, so dass das Füllgut 23 im Transportvolumen 24 des Transferbehälters 13 transportiert werden kann. Fig.5 shows the transfer container 13 for use in the transfer devices 10, 18 and 20 in cross section. The bottom of the transfer container 13 is formed by a closure 22 which is pivotally mounted on the transfer container 13 and is connected to a Fig.5 not shown drive device between the in Fig.5 shown closed position and the one in Fig.6 shown opening position can be adjusted by motor. In Fig.5 the closure 22 is in its closed position so that the filling material 23 can be transported in the transport volume 24 of the transfer container 13.

Fig. 6 zeigt den Transferbehälter 13 mit geöffnetem Verschluss 22. Durch Öffnen des Verschlusses 22 fällt das Füllgut 23 unter Schwerkrafteinfluss nach unten durch die Öffnung 25 des Transferbehälters 13. Das Transportvolumen 24 weist dabei einen sich nach untenhin erweiternden Querschnitt auf, so dass die Fallbewegung des Füllguts 23 nach Öffnen des Verschlusses 22 durch die Reibung an den Innenwandungen des Transferbehälters 13 nicht behindert wird. Fig.6 shows the transfer container 13 with the closure 22 open. By opening the closure 22, the filling material 23 falls downwards through the opening 25 of the transfer container 13 under the influence of gravity. The transport volume 24 has a cross-section that widens downwards, so that the falling movement of the filling material 23 after opening the closure 22 is not hindered by the friction on the inner walls of the transfer container 13.

Die Funktion der Transfereinrichtungen 10, 18 und 20 bei Übergabe des Füllguts 23 an die Befüllvorrichtung 04 der Schlauchbeutelmaschine 01 soll nachfolgend anhand der Skizzen in Fig. 7, Fig. 8 und Fig. 9 näher erläutert werden.The function of the transfer devices 10, 18 and 20 when transferring the filling material 23 to the filling device 04 of the tubular bag machine 01 is explained below using the sketches in Fig.7 , Fig.8 and Fig.9 be explained in more detail.

In Fig. 7 ist die Annäherung des Transferbehälters 13 mit einer Fördergeschwindigkeit V1 an die Übergabeposition in der Abgabestation 12 bzw. 21 oberhalb der Befüllvorrichtung 04 der Schlauchbeutelmaschine 01 gezeigt. Der Verschluss 22 ist noch in seiner Schließstellung und der Transferbehälter 13 somit vollständig geschlossen.In Fig.7 the approach of the transfer container 13 at a conveying speed V 1 to the transfer position in the delivery station 12 or 21 above the filling device 04 of the tubular bag machine 01 is shown. The closure 22 is still in its closed position and the transfer container 13 is thus completely closed.

In der in Fig. 8 dargestellten Position des Transferbehälters 13 hat sich dieser bereits sehr nahe an die Übergabeposition oberhalb der Befüllvorrichtung 04 angenähert. Nach Erreichen einer bestimmten Position vor der Übergabeposition, jedoch vor dem vollständigen Stillstand in der Übergabeposition wird, wie in Fig. 8 schematisiert dargestellt, der Verschluss 22 bereits geöffnet und der Übergabeprozess somit bereits vor dem vollständigen Stillstand begonnen. Dies bedeutet mit anderen Worten, obwohl sich der Transferbehälter 13 noch mit einer Fördergeschwindigkeit V2 in Richtung auf die Übergabeposition oberhalb der Befüllvorrichtung 04 bewegt, beginnt bereits der Übergabeprozess durch Öffnen des Verschlusses 22, so dass das Füllgut 23 in einer überlagerten Horizontal- und Vertikalbewegung in Richtung des Öffnungsquerschnitts der Befüllvorrichtung 04 fällt.In the Fig.8 In the position of the transfer container 13 shown, it has already approached very close to the transfer position above the filling device 04. After reaching a certain position before the transfer position, but before the complete standstill in the transfer position, as shown in Fig.8 shown schematically, the Closure 22 is already opened and the transfer process has therefore already begun before the system has come to a complete standstill. In other words, this means that although the transfer container 13 is still moving at a conveying speed V 2 in the direction of the transfer position above the filling device 04, the transfer process has already begun by opening the closure 22, so that the filling material 23 falls in a superimposed horizontal and vertical movement in the direction of the opening cross-section of the filling device 04.

Fig. 9 zeigt den Transferbehälter 13 nach Erreichen der Übergabeposition oberhalb der Befüllvorrichtung 04. In dieser Position hat der Transferbehälter 13 keine Horizontalgeschwindigkeit mehr, sondern ist vollständig zum Stillstand gekommen. Durch das vollständige Öffnen des Verschlusses 22 wurde das Füllgut 23 vollständig aus dem Transferbehälter 13 entleert und in die Befüllvorrichtung 04 übergeben. Sobald der Transferbehälter, wie in Fig. 9 schematisiert dargestellt, vollständig entleert ist, wird der Verschluss 22 durch die entsprechende Antriebseinrichtung wieder nach oben geschwenkt und der Transferbehälter dadurch geschlossen. Gleichzeitig wird der Transferbehälter 13 wieder in Bewegung gesetzt und in Richtung der Eingabestationen 11 bzw. 19 transportiert. Fig.9 shows the transfer container 13 after reaching the transfer position above the filling device 04. In this position, the transfer container 13 no longer has a horizontal speed, but has come to a complete standstill. By completely opening the closure 22, the filling material 23 was completely emptied from the transfer container 13 and transferred to the filling device 04. As soon as the transfer container, as in Fig.9 shown schematically, is completely emptied, the closure 22 is pivoted upwards again by the corresponding drive device and the transfer container is thereby closed. At the same time, the transfer container 13 is set in motion again and transported in the direction of the input stations 11 or 19.
