Description

Die Erfindung betrifft ein Verfahren zum Füllen und Verschweißen von Folienbeuteln gemäß dem Oberbegriff des Anspruchs 1 und eine Füll- und Schweißvorrichtung dazu gemäß Anspruch 4.The invention relates to a method for filling and welding foil bags according to the preamble of claim 1 and a filling and welding apparatus thereto according to claim 4.

Stand der TechnikState of the art

Es ist bekannt, Folienbeutel ohne Spout in taktenden Füllmaschinen mit Füllprodukt zu befüllen, wobei jeder Füllstation ein Ultraschallgenerator zum Verschweißen der befüllten Folienbeutel zugeordnet ist. Durch diese mehrreihige Folienbeutelverschweißung, die durch das parallele Durchtakten der Folienbeutel bedingt ist, ergeben sich vergleichsweise hohe Kosten, da jede Füllstation mit einem Ultraschallgenerator ausgestattet werden muss. Auch der Zeit- und Energieverlust ist durch die regelmäßigen Start-Stopp-Vorgänge vergleichsweise hoch.It is known to fill film bags without spout in clocking filling machines with filling product, each filling station is associated with an ultrasonic generator for welding the filled foil bag. This multi-row film bag welding, which is caused by the parallel passage through the film bag, results in comparatively high costs, since each filling station must be equipped with an ultrasonic generator. The time and energy loss is comparatively high due to the regular start-stop procedures.

Aufgabetask

Die Aufgabe der Erfindung besteht darin, ein Verfahren und eine Vorrichtung zum Füllen und Verschweißen von Folienbeuteln zur Verfügung zu stellen, die ein effizientes und zeitgünstiges Verschweißen der Folienbeutel ermöglichen.The object of the invention is to provide a method and an apparatus for filling and welding foil bags, which enable efficient and timely welding of the foil pouches.

Lösungsolution

Die Aufgabe wird gelöst durch das Verfahren nach Anspruch 1 und die Vorrichtung nach Anspruch 4. Bevorzugte Ausführungsformen und Weiterbildungen sind in den Unteransprüchen offenbart.The object is achieved by the method according to claim 1 and the device according to claim 4. Preferred embodiments and further developments are disclosed in the subclaims.

In dem Verfahren zum Füllen und Verschweißen von Folienbeuteln werden mehrere hintereinander von einem Drehkarussell aufgenommene Folienbeutel mittels mehrerer an dem Drehkarussell angeordneten Füllstationen befüllt, und anschließend werden die befüllten Folienbeutel mittels des Drehkarussells nacheinander an einer dem Drehkarussell zugeordneten und an dem Drehkarussell feststehend angeordneten Schweißstation zum Verschweißen der befüllten Folienbeutel vorbeigeführt, wobei die Schweißstation mindestens eine Schweißvorrichtung umfasst.In the method for filling and welding foil bags, a plurality of film bags received in succession from a rotary carousel are filled by means of several filling stations arranged on the rotary carousel, and then the filled film bags are successively welded by means of the rotary carousel to a welding station assigned to the rotary carousel and fixedly arranged on the rotary carousel the filled foil bag passes, wherein the welding station comprises at least one welding device.

Das Verfahren zum Füllen und Verschweißen ermöglicht, dass während eines kontinuierlichen Betriebs mehrere hintereinander angeordnete Folienbeutel befüllt werden, wobei die fertig befüllten Folienbeutel nacheinander, d.h. jeweils einzeln, an der dem Drehkarussell zugeordneten Schweißstation zum Verschweißen vorbeigeführt werden. Somit ist für alle befüllten Folienbeutel eine gemeinsame Schweißstation zum Verschweißen vorgesehen.The method of filling and welding allows that during a continuous operation a plurality of film bags arranged one behind the other are filled, wherein the finished filled foil bags successively, ie in each case individually, on the rotary carousel associated welding station are passed for welding. Thus, a common welding station is provided for welding for all filled foil bag.

An der Schweißstation können die Folienbeutel beispielsweise an ihren Oberkanten zusammengeschweißt werden. Bei mehreren Schweißvorrichtungen, die in unterschiedlicher Höhe der Schweißstation angeordnet sind, können die Folienbeutel in den jeweiligen Höhen, in denen sich die Schweißvorrichtungen befinden, geschweißt werden. Dabei können die Schweißvorrichtungen übereinander oder zueinander versetzt, nebeneinander angeordnet sein. Sind die mehreren Schweißvorrichtungen nebeneinander in gleicher Höhe angeordnet, so können verschiedene Bereiche in der gleichen Höhe der Folienbeutel geschweißt werden.At the welding station, the foil bags can be welded together, for example, at their upper edges. With several welding devices arranged at different heights of the welding station, the foil bags can be welded in the respective heights in which the welding devices are located. In this case, the welding devices can be arranged one above the other or offset from each other, arranged side by side. If the plurality of welding devices are arranged side by side at the same height, different areas can be welded in the same height of the film bag.

Daher können sowohl das Füllen als auch das Verschweißen in einem kontinuierlichen Prozess stattfinden, wobei mehreren Füllstationen eine Schweißstation zugeordnet ist.Therefore, both filling and welding can take place in a continuous process with multiple stations being associated with a welding station.

Vorzugsweise ist dem Drehkarussell eine einzige Schweißstation zugeordnet. In einer anderen Ausführungsform können dem Drehkarussell aber auch mehrere Schweißstationen zugeordnet sein, die vorzugsweise hintereinander und an dem Drehkarussell feststehend angeordnet sind.Preferably, the rotary carousel is associated with a single welding station. In another embodiment, however, the rotary carousel can also be assigned a plurality of welding stations, which are preferably arranged one behind the other and fixed to the rotary carousel.

Weiter kann das Verfahren die Schritte Aufnehmen der Folienbeutel mittels den Füllstationen zugeordneten Klammern und Aufdrücken der aufgenommenen Folienbeutel mittels der Klammern und danach Füllen der Folienbeutel mittels der Füllstationen umfassen.The method may further comprise the steps of picking up the foil pouches by means of staples associated with the filling stations and pressing the accommodated foil pouches by means of the clamps and then filling the foil pouches by means of the filling stations.

Die Folienbeutel können dem Drehkarussell ausgehend von einem Folienmagazin mittels eines Transferrads zugeführt werden. Das Magazin kann die Folienbeutel parallel, d.h. mehrreihig, ausgeben, und in dem Transferrad können die Folienbeutel hintereinander angeordnet werden und in dieser Anordnung an das Drehkarussell übergeben werden. Im Allgemeinen werden die Folienbeutel in einem zusammengelegten Zustand in dem Folienmagazin gelagert, so dass nach dem Aufnehmen eines solchen Folienbeutels mittels einer Klammer ein Aufdrücken des Folienbeutels erforderlich ist, so dass die Füllstation bzw. ein Füllventil der Füllstation Zugang zum Inneren des Folienbeutels erhalten kann.The film bags can be fed to the rotary carousel starting from a film magazine by means of a transfer wheel. The magazine can hold the foil bags in parallel, i. mehrreihig, spend, and in the transfer wheel, the foil bags can be arranged one behind the other and transferred in this arrangement to the rotary carousel. In general, the film bags are stored in a folded state in the film magazine, so that after receiving such a film bag by means of a clip pressing of the film bag is required so that the filling station or a filling valve of the filling station can get access to the interior of the film bag.

Eine Klammer kann zwei Klammerteile umfassen, die gegeneinander bewegbar ausgeführt sein können, so dass der Abstand zwischen ihnen veränderbar ist. Zum Aufnehmen eines Folienbeutels befindet sich die Klammer in einer ersten Position, d.h., die beiden Klammerteile weisen einen ersten Abstand auf, so dass der unbefüllte Folienbeutel, dessen beide Oberkanten aneinander liegen, mittels der Klammer aufgenommen werden kann.A clamp may comprise two clamp members, which may be made movable relative to each other, so that the distance between them is variable. To receive a foil bag, the staple is in a first position, that is, the two staple parts are at a first distance so that the unfilled foil bag, the two top edges of which abut one another, can be picked up by means of the staple.

Zum Aufdrücken des aufgenommenen Folienbeutels können die beiden Klammerteile aufeinander zu bewegt werden, so dass sich die Klammer in einer zweiten Position befindet, wobei die beiden Klammerteile einen zweiten Abstand zueinander aufweisen, der kleiner als der erste Abstand ist.To press the recorded foil bag, the two staple parts can be moved towards each other, so that the clip is in a second position, wherein the two bracket parts have a second distance from one another which is smaller than the first distance.

Das Füllen eines Folienbeutels kann mittels eines Füllventils der Füllstation erfolgen, die den Folienbeutel aufgenommen hat.The filling of a foil bag can take place by means of a filling valve of the filling station, which has received the foil bag.

Zudem kann das Verfahren die folgenden Schritte umfassen, die jeweils während der Drehung des Drehkarussells erfolgen: Schließen der befüllten Folienbeutel durch Auseinanderziehen der Klammern, wodurch jeweils zwei Oberkanten der befüllten Folienbeutel aneinandergelegt werden, und danach Verschweißen der jeweils zwei aneinandergelegten Oberkanten mittels der dem Drehkarussell zugeordneten Schweißstation.In addition, the method may comprise the following steps, which respectively take place during the rotation of the rotary carousel: closing the filled foil pouches by pulling apart the clamps, whereby two upper edges of the filled foil pouches are placed against each other, and then welding the two adjacent upper edges by means of the rotary carousel welding station.

Nach Beenden des Füllens kann der befüllte Folienbeutel mittels der Klammer auseinandergezogen werden, wodurch die beiden Oberkanten aneinander gelegt werden, so dass kein Abstand mehr zwischen ihnen besteht. Das Auseinanderziehen kann durch ein Bewegen der beiden Klammerteile voneinander weg erfolgen. Die Klammer befindet sich dann in einer dritten Position, d.h., die beiden Klammerteile weisen einen dritten Abstand zueinander auf, der dem ersten Abstand entspricht.After completing the filling of the filled foil bag can be pulled apart by means of the clip, whereby the two upper edges are placed together so that there is no distance between them. The pulling apart can be done by moving the two staple parts away from each other. The clip is then in a third position, that is, the two clip parts have a third distance from each other corresponding to the first distance.

Durch die Drehung des Drehkarussells um die Drehachse wird der befüllte Folienbeutel dann an der Schweißstation vorbeigeführt, und es erfolgt ein Verschweißen der zwei aneinandergelegten Oberkanten des Folienbeutels.By the rotation of the rotary carousel about the axis of rotation of the filled film bag is then passed past the welding station, and there is a welding of the two adjacent upper edges of the film bag.

Eine Füll- und Schweißvorrichtung zum Durchführen des Verfahrens, wie oben oder weiter unten beschrieben, umfasst ein Drehkarussell mit mehreren daran angeordneten Füllstationen zum Füllen von Folienbeuteln und eine dem Karussell zugeordnete und an dem Drehkarussell feststehend angeordnete Schweißstation zum Verschweißen der befüllten Folienbeutel, wobei die Schweißstation mindestens eine Schweißvorrichtung umfasst.A filling and welding apparatus for carrying out the method as described above or below comprises a rotary carousel with a plurality of filling stations disposed thereon for filling foil bags and a welding station associated with the carousel and fixedly arranged on the rotary carousel for welding the filled foil bags, the welding station comprises at least one welding device.

Das Drehkarussell 2 ist um eine Drehachse 5 drehbar ausgebildet, so dass Folienbeutel 6, 7, 8, 9, 10, die mittels Klammern 11, 12, 13, 14, 15 der Füllstationen 3 gehalten werden, bewegt und somit mittels des Drehkarussells 2 an der Schweißstation 4 vorbeigeführt werden können. Die Folienbeutel 6, 7, 8, 9, 10 werden dem Drehkarussell 2 mittels eines Einlaufsterns 19 zugeführt, und nach dem Füllen und Verschweißen werden diese Folienbeutel 6, 7, 8, 9, 10 von dem Drehkarussell 2 mittels eines Auslaufsterns 20 ausgeleitet.The rotary carousel 2 is designed to be rotatable about an axis of rotation 5, so that foil bags 6, 7, 8, 9, 10, which are held by means of clamps 11, 12, 13, 14, 15 of the filling stations 3, are moved and thus by means of the rotary carousel 2 the welding station 4 can be passed. The foil bags 6, 7, 8, 9, 10 are fed to the rotary carousel 2 by means of an infeed star 19, and after filling and welding these foil bags 6, 7, 8, 9, 10 are discharged from the rotary carousel 2 by means of an outlet star 20.

Jeder Füllstation 3 ist eine Klammer 11, 12, 13, 14, 15 zugeordnet, die hier zweiteilig ausgeführt ist, wobei die beiden Klammerteile entlang der mit Pfeilen gekennzeichneten Richtungen 16 aufeinander zu bzw. voneinander weg bewegt werden können. Zum Aufnehmen eines Folienbeutels 6 befindet sich eine Klammer 11 in einer ersten Position, d.h., die beiden Klammerteile weisen einen ersten Abstand d1 auf, so dass der unbefüllte Folienbeutel 6, dessen beide Oberkanten aneinander liegen, mittels der Klammer 11 aufgenommen werden kann.Each filling station 3 is associated with a clip 11, 12, 13, 14, 15, which is here made in two parts, wherein the two clip parts along the arrowed directions 16 can be moved towards each other or away from each other. For receiving a foil bag 6, a staple 11 is in a first position, that is, the two staple parts have a first distance d1, so that the unfilled foil bag 6, both upper edges of which lie against each other, can be picked up by means of the staple 11.

Um ein Füllen des aufgenommenen Folienbeutels 7, 8 vornehmen zu können, wird dieser mittels der Klammer 12, 13 aufgedrückt, d.h., zwischen den beiden aneinander liegenden Oberkanten wird ein Abstand erzeugt. Dazu werden die beiden Klammerteile entlang der mit Pfeilen gekennzeichneten Richtungen aufeinander zu bewegt. Die Klammer 12, 13 befindet sich dann in einer zweiten Position, d.h., die beiden Klammerteile weisen einen zweiten Abstand d2 zueinander auf, der kleiner als der erste Abstand ist.In order to make a filling of the received foil bag 7, 8, this is pressed by means of the clamp 12, 13, that is, between the two adjacent upper edges a distance is created. For this purpose, the two staple parts are moved towards each other along the directions marked with arrows. The clamp 12, 13 is then in a second position, that is, the two clamp members have a second distance d2 to each other that is smaller than the first distance.

Nach dem Aufdrücken des aufgenommenen Folienbeutels 7, 8 erfolgt ein Füllen mit Füllprodukt mittels der Füllstation 3. Nach Beenden des Füllens wird der befüllte Folienbeutel 9 geschlossen, in dem die Klammer 14 auseinandergezogen wird, wodurch die beiden Oberkanten aneinander gelegt werden. Das Auseinanderziehen erfolgt durch Bewegen der beiden Klammerteile voneinander weg entlang der mit Pfeilen gekennzeichneten Richtungen. Die Klammer 14 befindet sich dann in einer dritten Position, d.h., die beiden Klammerteile weisen einen dritten Abstand d3 zueinander auf, der dem ersten Abstand d1 entspricht.After pressing the recorded film bag 7, 8 is filled with filling product by means of the filling station 3. After completing the filling of the filled film bag 9 is closed, in which the clip 14 is pulled apart, whereby the two upper edges are placed together. The pulling apart is done by moving the two staple parts away from each other along the arrowed directions. The clamp 14 is then in a third position, that is, the two clamp members have a third distance d3 from each other corresponding to the first distance d1.

Durch die Drehung des Drehkarussells um die Drehachse 5 wird der befüllte Folienbeutel 9, 10 dann an der Schweißstation 4 vorbeigeführt, und es erfolgt ein Verschweißen der zwei aneinandergelegten Oberkanten des Folienbeutels 10.As a result of the rotation of the rotary carousel about the axis of rotation 5, the filled film bag 9, 10 is then guided past the welding station 4, and the two folded upper edges of the film bag 10 are welded together.

Somit können in der Füll- und Schweißvorrichtung 1 während eines kontinuierlichen Betriebs mehrere hintereinander angeordnete Folienbeutel 6, 7, 8, 9 befüllt werden, wobei die fertigbefüllten Folienbeutel 9, 10 nacheinander, d.h. jeweils einzeln, an der dem Drehkarussell 2 zugeordneten Schweißstation 4 zum Verschweißen vorbeigeführt werden.Thus, in the filling and welding device 1 during a continuous operation a plurality of successively arranged film bags 6, 7, 8, 9 are filled, wherein the ready-filled foil pouches 9, 10 successively, ie in each case individually, are guided past the welding station 4 associated with the rotary carousel 2 for welding.

Daher können sowohl das Füllen als auch das Verschweißen in einem kontinuierlichen Prozess stattfinden, wobei mehreren Füllstationen 3 eine Schweißstation 4 zugeordnet ist.Therefore, both the filling and the welding can take place in a continuous process, wherein a plurality of filling stations 3, a welding station 4 is assigned.

Der Füll- und Schweißvorrichtung vorgeordnet können ein Folienmagazin zur parallelen Ausgabe von Folienbeuteln und ein Transferrad zur Übergabe der ausgegebenen Folienbeutel an die Füll- und Schweißvorrichtung vorgesehen sein. An dem Transferrad werden die vom Magazin parallel ausgegebenen Folienbeutel hintereinander angeordnet und in dieser Anordnung an das Drehkarussell übergeben.Upstream of the filling and welding device may be provided a film magazine for the parallel dispensing of film bags and a transfer wheel for transferring the dispensed film bags to the filling and welding device. At the transfer wheel, the film bags issued in parallel by the magazine are arranged one behind the other and transferred in this arrangement to the rotary carousel.

Zudem kann der Füll- und Schweißvorrichtung 1 auch ein Transferrad 19 vorgeordnet sein.Downstream of the filling and welding device 1, a transfer wheel 20 for receiving the filled and sealed foil pouches 10 arranged one behind the other and an output device can be provided. In addition, the filling and welding device 1 may also be arranged upstream of a transfer wheel 19.

Figur 2 eine schematische, perspektivische Seitenansicht einer Schweißstation 4 mit zwei Schweißvorrichtungen 17, 18, die hier übereinanderliegend in einem bestimmten Abstand d4 zueinander angeordnet sind. Somit können an der Schweißstation 4 vorbeigeführte Folienbeutel in zwei entsprechend beabstandeten Bereichen verschweißt werden. Es kann auch vorgesehen sein, dass nur die eine oder die andere Schweißvorrichtung 17, 18 betrieben wird, so dass Folienbeutel entsprechend nur in einem Bereich verschweißt werden. FIG. 2 a schematic, perspective side view of a welding station 4 with two welding devices 17, 18 which are superimposed here at a certain distance d4 to each other. Thus, foil bags guided past the welding station 4 can be welded in two correspondingly spaced regions.

Figur 3 zeigt ein Flussdiagram eines Verfahrens zum Füllen und Verschweißen eines Folienbeutels mittels der oben oder weiter unten erwähnten Füll- und Schweißvorrichtung. Im Schritt 100 wird ein Folienbeutel mittels einer Klammer aufgenommen. Die Klammer ist einer Füllstation eines Drehkarussells mit mehreren Füllstationen und entsprechend mehreren Klammern zugeordnet, mit der im Folgenden ein Füllen des Folienbeutels erfolgen soll, wobei die Füllstationen und die Klammern sich durch die Drehung des Drehkarussells auf Kreisbahnen bewegen. Beispielsweise kann eine Klammer zwei Klammerteile umfassen, die aufeinander zu bzw. voneinander weg bewegt werden können. Zum Aufnehmen des Folienbeutels befindet sich die Klammer in einer ersten Position, d.h., die beiden Klammerteile weisen einen ersten Abstand auf, so dass der unbefüllte Folienbeutel, dessen beide Oberkanten aneinander liegen, mittels der Klammer aufgenommen werden kann. FIG. 3 shows a flow diagram of a method for filling and welding a film bag by means of the above-mentioned or below-mentioned filling and welding device. In step 100, a foil bag is received by means of a clamp. The clamp is associated with a filling station of a rotary carousel having a plurality of filling stations and correspondingly a plurality of clamps with which a filling of the foil bag is to take place in the following, wherein the filling stations and the clamps move through the rotation of the rotary carousel in circular paths. For example, a staple may comprise two staple parts that can be moved toward and away from each other. For receiving the foil bag, the clamp is in a first position, ie, the two clamp parts have a first distance, so that the unfilled foil bag, both upper edges of which lie against each other, can be picked up by means of the clamp.

Im Schritt 101 erfolgt während der Drehung des Drehkarussells ein Aufdrücken des aufgenommenen Folienbeutels mittels der Klammer. Dazu werden die beiden Klammerteile aufeinander zu bewegt, so dass sich die Klammer in einer zweiten Position befindet, d.h., die beiden Klammerteile weisen einen zweiten Abstand zueinander auf, der kleiner als der erste Abstand ist. Durch das Aufdrücken entsteht zwischen den zwei aneinanderliegenden Oberkanten des Folienbeutels ein Abstand, so dass im Schritt 102 ein Füllen des Folienbeutels mittels der Füllstation durchgeführt werden kann.In step 101, during the rotation of the rotary carousel, a pressing of the received foil bag takes place by means of the clamp. For this purpose, the two clamp members are moved towards each other, so that the clamp is in a second position, that is, the two clamp members have a second distance to each other, which is smaller than the first Distance is. By pressing creates a gap between the two adjacent upper edges of the film bag, so that in step 102, a filling of the film bag can be carried out by means of the filling station.

Nach dem Füllen erfolgt im Schritt 103 während der Drehung des Drehkarussells ein Schließen des befüllten Folienbeutels durch ein Auseinanderziehen der Klammer, wodurch die beiden Oberkanten des befüllten Folienbeutels wieder aneinander gelegt werden. Das Auseinanderziehen erfolgt durch Bewegen der beiden Klammerteile voneinander weg. Die Klammer befindet sich dann in einer dritten Position, der der ersten Position entspricht, so dass die beiden Klammerteile einen dritten Abstand zueinander aufweisen, der dem ersten Abstand entspricht.After filling, in step 103, during the rotation of the rotary carousel, the filled foil bag is closed by pulling the clip apart, whereby the two upper edges of the filled foil bag are put back together. The pulling apart is done by moving the two staple parts away from each other. The clamp is then in a third position corresponding to the first position, so that the two clamp members have a third distance from each other corresponding to the first distance.

Im Schritt 104 erfolgt während der Drehung des Drehkarussells ein Verschweißen des Folienbeutels mittels der Schweißstation, d.h. mittels mindestens einer Schweißvorrichtung der feststehend angeordneten Schweißvorrichtung, durch das Vorbeiführen des Folienbeutels an der Schweißstation wobei die beiden aneinanderliegenden Oberkanten und/oder andere Bereiche des Folienbeutels verschweißt werden können. Die Schweißstation ist an dem Drehkarussells, z.B. in seiner Peripherie, feststehend angeordnet.In step 104, during the rotation of the rotary carousel, the foil bag is welded by means of the welding station, i. by means of at least one welding device of the fixedly arranged welding device, by passing the film bag past the welding station, wherein the two adjoining top edges and / or other regions of the film bag can be welded. The welding station is connected to the rotary carousel, e.g. in its periphery, fixedly arranged.

Da der Folienbeutel an einem sich drehenden Drehkarussell angeordnet ist, wird der Folienbeutel nach dem Aufnehmen mittels der Klammer durch das Drehkarussell mitbewegt, so dass er sich während des beschriebenen Verfahrens entlang des Umfangs des Drehkarussells bewegt und somit zu der feststehend angeordneten Schweißstation, die sich in der Peripherie des Drehkarussells befindet, zum Durchführen des Schweißprozesses gelangt.Since the film bag is arranged on a rotating rotary carousel, the film bag is moved by the rotary carousel after picking up by means of the clip, so that it moves along the circumference of the rotary carousel during the described method and thus to the stationary arranged welding station, which in the periphery of the rotary carousel, passes to perform the welding process.

Dementsprechend kann das Verfahren zum Füllen und Verschweißen mehrerer Folienbeutel, die an dem Drehkarussell hintereinander angeordnet sind, verwendet werden, wobei das Füllen und anschließende Verschweißen kontinuierlich erfolgen kann.Accordingly, the method for filling and welding a plurality of film bags, which are arranged on the rotary carousel in succession, can be used, wherein the filling and subsequent welding can be carried out continuously.
