Abstract

The invention relates to a method for introducing into packaging containers flexible foil packages filled with an amorphous product, in which a group of bags made up of foil packages (6) lying one on top of the other in overlapping formation is conveyed horizontally and introduced vertically into the packaging container (1) over a curved conveying section (4). According to the invention, the foil packages are conveyed flat on a conveyor belt (5) without overlap and following one another in series and transferred to an intermediate belt (7) driven at a slower transport speed, thus forming a bag group of imbricated foil packages. After a predetermined number of foil packages assigned to the packaging container (1) have been received, the intermediate belt (7) is accelerated for a short period, a bag- group section with a subsequent gap being formed. The bag-group section is introduced over the curved conveying section (4) into the packaging container (1). After the filling operation is complete, during the time interval given by the gap, the deflection element (12) is withdrawn from the packaging container (1), the packaging container (1) is transported away and the deflecting element (12) is inserted into a following, empty packaging container. <IMAGE>

Description

Die Erfindung bezieht sich gattungsgemäß auf ein Verfahren zum Einbringen von mit nicht lagefixiertem Gut gefüllten flexiblen Folienverpackungen, insbesondere mit riesel- oder fließfähigem Gut gefüllten Flachbeuteln, in Verpackungsbehälter, bei dem ein Beutelstrang aus schuppenförmig aufeinanderliegenden Folienver­packungen horizontal herangeführt und über einen bogenförmigenThe invention relates generically to a method for introducing flexible film packaging filled with non-fixed material, in particular flat bags filled with free-flowing or flowable material, into packaging containers, in which a strand of bags consisting of film packaging lying on top of one another in a horizontal manner is fed horizontally and over an arcuate one

Förderabschnitt vertikal in den Verpackungsbehälter eingeführt wird, der an einer Stirnwand beginnend gefüllt wird, wobei der Beutelstrang im bogenförmigen Förderabschnitt zwischen Trans­portbändern gehalten wird und im Verpackungsbehälter jede Folienverpackung an einem in den Verpackungsbehälter eintauchen­den Umlenkelement des bogenförmigen Förderabschnitts anliegt und wobei der Verpackungsbehälter unter der Druckwirkung der eingeführten Folienverpackungen vorgeschoben wird.The conveying section is inserted vertically into the packaging container, which is filled beginning at an end wall, the string of bags being held in the arcuate conveying section between conveyor belts and in the packaging container each foil packaging abuts a deflecting element of the arched conveying section which is immersed in the packaging container, and the packaging container is under the pressure effect of the imported film packaging is advanced.

Bei dem bekannten gattungsgemäßen Verfahren (FR-A-22 10 540) muß beim Wechsel der Verpackungsbehälter der Herantransport von Folienverpackungen unterbrochen werden. Bei dem bekannten Ver­fahren wird kurz vor dem Ende des Füllvorganges das Förderband für die schuppenförmig aufeinander liegenden Folienverpackungen kurzzeitig stillgesetzt und die noch im bogenförmigen Förderab­schnitt befindlichen Folienverpackungen in den Verpackungsbe­hälter eingebracht. Danach wird das Umlenkelement aus dem Ver­packungsbehälter herausbewegt ein nachfolgender leerer Ver­packungsbehälter in die Füllstellung gebracht. Erst dann wird das Antransportieren von neuen Folienverpackungen fortgesetzt und ein neuer Füllvorgang eingeleitet. Zur Vermeidung einer störenden Unterbrechung im Antransport des abzupackenden Materials ist es aus der GB-A-20 46 711 bekannt, mit einem Be­schleunigungsband zu arbeiten. Das aus dieser Druckschrift be­kannte Verfahren ist geeignet zum Abpacken von Kartonagen. Die Kartonagen werden von einem ersten Förderband auf ein daran anschließendes, mit kleinerer Transportgeschwindigkeit bewegtes Transportband übergeben. Dabei werden die Kartonagen schuppen­förmig aufeinander abgelegt. Nachdem eine vorgegebene, in einem Verpackungsbehälter abzupackende Anzahl an Kartonagen auf dem Transportband aufliegt, wird das Transportband beschleunigt und die schuppenförmig übereinander liegenden Kartonagen mit hoher Geschwindigkeit im freien Fall in den Verpackungsbehälter ein­geführt. Dieses Verfahren ist für Folienverpackungen mit nicht lagefixiertem Gut ungeeignet. Aufgrund der hohen Aufprallge­schwindigkeiten im Verpackungsbehälter würde das Füllgut ver­rutschen, so daß eine hohe Fülldichte nicht erreichbar wäre. Bei empfindlichem Füllgut, z. B. brüchigen Chips, kann es ferner zu einer Beschädigung des Füllguts kommen.In the known generic method (FR-A-22 10 540) the transport of film packaging has to be interrupted when changing the packaging container. In the known method, shortly before the end of the filling process, the conveyor belt for the film packages lying one above the other in the form of scales is stopped briefly and the film packages still located in the curved conveyor section are introduced into the packaging container. Then the deflection element is moved out of the packaging container and a subsequent empty packaging container is brought into the filling position. Only then will the transport of new film packaging continue and a new filling process initiated. In order to avoid a disruptive interruption in the transport of the material to be packed, it is known from GB-A-20 46 711 to work with an acceleration belt. The method known from this publication is suitable for packaging cardboard boxes. The cardboard boxes are transferred from a first conveyor belt to a subsequent conveyor belt that moves at a lower transport speed. The cardboard boxes are stacked on top of one another. After a predetermined number of cardboard boxes to be packed in a packaging container rests on the conveyor belt, the conveyor belt is accelerated and the cardboard boxes lying one above the other at high speeds Free fall speed introduced into the packaging container. This process is unsuitable for film packaging with goods that are not fixed in position. Due to the high impact speeds in the packaging container, the contents would slip, so that a high filling density would not be achievable. With sensitive contents, e.g. B. fragile chips, it can also damage the product.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren so auszubilden, daß ein dichtes und füllgutschonendes Abpacken der Folienverpackungen möglich ist, und zwar bei hoher Leistung ohne störende Unterbrechung im Antransport der Folienverpackungen. Ferner besteht die Aufgabe, eine Vorrich­tung zur Durchführung des Verfahrens anzugeben.The invention has for its object to design the generic method so that a tight and filling-gentle packaging of the film packaging is possible, with high performance without disruptive interruption in the transport of the film packaging. There is also the task of specifying a device for carrying out the method.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Folien­verpackungen ohne Überlappung in Reihe hintereinander flach­liegend auf einem Förderband herangeführt und auf ein mit ge­ringerer Transportgeschwindigkeit angetriebenes Zwischenband übergeben werden unter Bildung eines Beutelstrangs aus schup­penförmig aufeinanderliegenden Folienverpackungen, daß das Zwi­schenband nach Aufnahme einer vorgegebenen, dem Verpackungs­behälter zugeordneten Anzahl von Folienverpackungen kurzzeitig beschleunigt wird, wobei ein Beutelstrangabschnitt mit nachfol­gender Lücke ausgebildet wird, daß der Beutelstrangabschnitt über den bogenförmigen Förderstreckenabschnitt in den Ver­packungsbehälter eingeführt wird und daß nach Beendigung des Füllvorganges während des durch die Lücke vorgegebenen Zeit­intervalls das Umlenkelement aus dem Verpackungsbehälter heraus­gezogen, der Verpackungsbehälter abtransportiert und das Umlenk­element in einen nachfolgenden leeren Verpackungsbehälter ein­gesetzt wird. Erfindungsgemäß hat das Schuppen der Folienver­ packungen den doppelten Effekt, daß zum einen ohne Leistungs­minderung die Transportgeschwindigkeit und die daraus resultie­renden Stoßkräfte am Ende der Förderstrecke verkleinert werden und daß zum anderen die Folienverpackungen sich im Verpackungs­behälter selbst führen. Eine Zwischensortierung in einem Magazin entfällt also. Während bei den bekannten Verfahren (GB-A-20 46 711) das abzupackende Material mit undefinierter Geschwindigkeit gegen den Behälterboden des Verpackungsbehälters gestoßen wird, und zwar ohne vorder- und rückseitige Führung, werden die ab­zupackenden Folienverpackungen erfindungsgemäß mit gezielter Fördergeschwindigkeit bis zum Boden des Verpackungsbehälters transportiert, wobei sie vorderseitig sowie rückseitig abgestützt sind, so daß sich das gleichmäßig in der Verpackung verteilte Gut nicht einseitig verlagern kann. Auf diese Art und Weise ist eine dichte Füllung des Verpackungsbehälters mit Folienverpackun­gen gewährleistet, ohne daß dabei der Inhalt der Folienverpackun­gen schädlichen Druckbelastungen ausgesetzt wird.To achieve this object, the invention teaches that the film packs are brought one after the other in a row lying flat on a conveyor belt and transferred to an intermediate belt driven at a lower transport speed, forming a string of bags made of film packs lying one above the other in such a way that the intermediate belt after receiving a predetermined packaging container assigned number of film packages is accelerated briefly, a bag strand section with a subsequent gap being formed, the bag strand section being introduced into the packaging container via the arcuate conveyor section and that after the filling process has ended, the deflection element is pulled out of the packaging container during the time interval predetermined by the gap, which Transported packaging container and the deflecting element is inserted into a subsequent empty packaging container. According to the shed the film ver packs the double effect that, on the one hand, the transport speed and the resulting impact forces at the end of the conveyor line are reduced without a reduction in performance and, on the other hand, that the film packaging guides itself in the packaging container. There is no intermediate sorting in a magazine. While in the known methods (GB-A-20 46 711) the material to be packaged is pushed against the container bottom of the packaging container at an undefined speed, and specifically without front and rear guidance, the film packages to be packaged are, according to the invention, at a specific conveying speed to the bottom of the packaging container transported, where they are supported on the front and back, so that the goods evenly distributed in the packaging can not shift on one side. In this way, a tight filling of the packaging container with film packaging is ensured without the contents of the film packaging being exposed to harmful pressure loads.

Günstig auf den Füllvorgang des Verpackungsbehälters mit Folien­verpackungen wirkt sich aus, wenn der Verpackungsbehälter allein durch die in den Behälter geförderten Folienverpackungen vorge­schoben wird. Dabei sollte der Verpackungsbehälter auf einer ortsfesten Unterlage verschoben werden können. In einem solchen Fall wird mit zunehmender Füllung das Gewicht des Verpackungs­behälters größer und der S taudruck entsprechend größer. Dies ist günstig, weil bei erst wenigen in den Verpackungsbehälter eingefüllten Verpackungen der Staudruck möglichst klein sein soll, weil sonst die Gefahr besteht, daß die einzelne Folienver­packung zu sehr zusammengedrückt wird und dann das Füllgut beschädigt werden könnte. Wenn jedoch viele Verpackungen im Ver­packungsbehälter sind, ist ein großes elastisches Polster vorhan­den, das ein zu starkes Zusammenpressen einer einzelnen Folien­verpackung kompensiert.The filling process of the packaging container with film packaging has a favorable effect if the packaging container is advanced solely through the film packaging conveyed into the container. The packaging container should be able to be moved on a stationary surface. In such a case, the weight of the packaging container increases with increasing filling and the dynamic pressure increases correspondingly. This is favorable because, in the case of only a few packages filled into the packaging container, the dynamic pressure should be as small as possible, because otherwise there is a risk that the individual foil packaging is compressed too much and the contents could then be damaged. However, if there is a lot of packaging in the packaging container, there is a large elastic cushion which compensates for too much compression of a single film packaging.

Die Erfindung bezieht sich ferner auf eine zur Durchführung des Verfahrens geeignete Vorrichtung - mit Transportbahn für Ver­packungsbehälter, im wesentlichen horizontal verlaufendem Förder­streckenabschnitt mit tragenden Transportmitteln für das Zuführen von Folienverpackungen, an den horizontalen Förderstreckenab­schnitt anschließenden bogenförmigen Förderstreckenabschnitt mit auf der Bogeninnenseite angeordnetem unteren Transportband und auf der Bogenaußenseite angeordnetem oberen Transportband, zwi­schen denen die Folienverpackungen einklemmbar sind, wobei das obere Transportband an einer Übergabestelle zum horizontalen För­derstreckenabschnitt über eine Umlenkrolle sowie an einem verti­kalen Endabschnitt über ein Umlenkelement geführt ist, das in den Verpackungsbehälter einführbar ist. Diese Vorrichtung ist erfin­dungsgemäß dadurch gekennzeichnet, daß der horizontale Förder­streckenabschnitt ein Förderband für die Zufuhr von Folienver­packungen sowie ein daran anschließendes, tiefer liegend angeord­netes und mit geringer Transportgeschwindigkeit angetriebenes Zwischenförderband aufweist, wobei die Folienverpackungen ohne Überlappung in Reihe hintereinander flach liegend auf dem Förder­band heranführbar und auf dem Zwischenförderband schuppenförmig unter Bildung eines Beutelstrangs ablegbar sind und daß das Zwi­schenförderband kurzzeitig auf eine höhere Geschwindigkeit um­schaltbar ist, wobei eine Lücke im Beutelstrang ausbildbar ist. Vorzugsweise ist die Umlenkrolle des oberen Transportbandes höhen­verstellbar angeordnet. Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß das obere Transport­band über einen Bandspeicher und ein in Bandlaufrichtung ver­stellbares Umlenkelement geführt ist. - Der Übergang von der Fül­lung eines Verpackungsbehälters auf den nächsten leeren Ver­packungsbehälter geschieht in der Weise, daß beim Übergang von der Förderstrecke mit den einzeln geförderten Folienverpackungen zu der Förderstrecke, wo die Schuppung stattfindet, durch schnel­ lere bzw. langsamere Förderung eine Lücke geschaffen wird. So­bald die Lücke am Verpackungsbehälter ankommt, ist es möglich, den vollen Verpackungsbehälter durch einen leeren Verpackungs­behälter zu ersetzen. Das kann beispielsweise dadurch geschehen, daß das die im Verpackungsbehälter gebildete Stapelstelle über­fassende Umlenkelement des bogenförmigen Förderstreckenabschnitts in Bandlaufrichtung zurück- und dann beim neuen Behälter wieder vorgestellt wird. Diese Art des Übergangs ist dann erforderlich, wenn der Verpackungsbehälter nur in der Ebene seiner Aufstands­fläche verschoben werden kann. Sofern der Verpackungsbehälter heb- und senkbar ist, ist diese Art des Übergangs nicht erforder­lich. Wenn gleichwohl das Umlenkelement auch dann noch in Band­laufrichtung verstellbar ist, dann ist dies deshalb sinnvoll, um eine Anpassung an unterschiedlich hohe Verpackungsbehälter vor­nehmen zu können. Zur Aufrechterhaltung der Bandspannung sollte das obere Transportband des bogenförmigen Förderstreckenab­schnitts durch einen Bandspeicher laufen. Der Bandspeicher kompen­siert dann die sich durch die Verstellung des Umlenkelements oder durch unterschiedliche Beladungshöhe des bogenförmigen Förder­bandabschnittes sich ergebende, unterschiedliche Bandlängen im Bereich der bogenförmigen Führung.The invention further relates to a device suitable for carrying out the method - with a transport path for packaging containers, a substantially horizontally running conveyor section with load-bearing transport means for feeding film packaging, an arcuate conveyor section adjoining the horizontal conveyor section with a lower conveyor belt arranged on the inside of the sheet, and on the Upper conveyor belt arranged on the outside of the sheet, between which the film packagings can be clamped, the upper conveyor belt being guided at a transfer point to the horizontal conveyor section via a deflecting roller and at a vertical end section via a deflecting element which can be inserted into the packaging container. According to the invention, this device is characterized in that the horizontal conveyor section has a conveyor belt for the supply of film packaging and an adjoining, lower-lying intermediate conveyor belt driven at a low transport speed, the film packaging being able to be brought up and lying flat on the conveyor belt in series without overlap the intermediate conveyor belt can be deposited in a scale-like manner with the formation of a bag strand and that the intermediate conveyor belt can be briefly switched over to a higher speed, a gap in the bag strand being able to be formed. The deflection roller of the upper conveyor belt is preferably arranged to be adjustable in height. A further advantageous embodiment of the invention is characterized in that the upper conveyor belt is guided over a belt store and a deflection element which is adjustable in the direction of belt travel. - The transition from the filling of a packaging container to the next empty packaging container is done in such a way that when moving from the conveyor line with the individually conveyed film packaging to the conveyor line where the descaling takes place, by quick a slower or slower funding a gap is created. As soon as the gap arrives at the packaging container, it is possible to replace the full packaging container with an empty packaging container. This can be done, for example, by returning the deflecting element of the arcuate conveyor section section that forms the stacking point formed in the packaging container in the direction of belt travel and then introducing it again in the new container. This type of transition is necessary if the packaging container can only be moved in the plane of its contact area. If the packaging container can be raised and lowered, this type of transition is not necessary. If the deflecting element is still adjustable in the direction of tape travel, then this makes sense in order to be able to adapt to packaging containers of different heights. To maintain the belt tension, the upper conveyor belt of the curved conveyor section should run through a belt store. The belt store then compensates for the different belt lengths in the region of the curved guide resulting from the adjustment of the deflecting element or from different loading heights of the curved conveyor belt section.

Im folgenden wird die Erfindung anhand einer lediglich ein Aus­führungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Die einzige Figur zeigt in schematischer Darstellung eine Vorrich­tung zum Einbringen von mit nicht lagefixiertem Gut gefüllten flexiblen Folienverpackungen in einen Verpackungsbehälter. Bei den Folienverpackungen handelt es sich im Ausführungsbeispiel um Flachbeutel, die mit einem riesel- oder fließfähigen Füllgut gefüllt sind.In the following, the invention will be explained in more detail with reference to a drawing showing only one embodiment. The single figure shows a schematic representation of a device for introducing flexible film packaging filled with non-fixed material into a packaging container. In the exemplary embodiment, the film packagings are flat bags which are filled with a pourable or flowable filling material.

Die Vorrichtung umfaßt zwischen einer in der Figur nicht darge­stellten Füll- und Verschließmaschine zum Abfüllen des Füllgutes in Flachbeutel und der in Form eines quaderförmigen, oben offenen Faltkartons 1 dargestellten Verpackungsbehälters drei charakte­ristische Förderstreckenabschnitte 2, 3, 4.The device comprises three characteristic conveyor sections 2, 3, 4 between a filling and closing machine (not shown in the figure) for filling the filling material in flat bags and the packaging container shown in the form of a rectangular, open-top folding carton 1.

Der Förderstreckenabschnitt 2 verläuft in der Horizontalen und besteht aus einem endlosen Förderband 5, auf das die von der Füll- und Verschließmaschine gefüllten Beutel 6 mit gleichmäßig verteiltem Füllgut flach und in Reihe hintereinander abgelegt wer­den. An das Förderband 5 schließt sich im zweiten Förderstrecken­abschnitt 3 ein weiteres, ebenfalls horizontal, aber etwas tiefer liegendes Förderband 7 an. Dieses Förderband 7 hat eine gerin­gere Transportgeschwindigkeit als das Förderband 5. Aufgrund der unterschiedlichen Fördergeschwindigkeiten der beiden Bänder 5, 7 werden die Flachbeutel 6 an der Übergangsstelle vom Band 5 auf das Band 7 geschuppt. Durch kurzfristiges Umschalten auf eine höhere Geschwindigkeit kann in dem geschuppten Beutelstrang 8 eine Lücke gebildet werden.The conveyor section 2 runs horizontally and consists of an endless conveyor belt 5, on which the bags 6 filled by the filling and closing machine with evenly distributed contents are placed flat and in a row one behind the other. In the second conveyor section 3, the conveyor belt 5 is followed by a further conveyor belt 7, which is also horizontal, but somewhat lower. This conveyor belt 7 has a lower transport speed than the conveyor belt 5. Because of the different conveyor speeds of the two belts 5, 7, the flat bags 6 are scaly at the transition point from the belt 5 to the belt 7. By briefly switching to a higher speed, a gap can be formed in the flaky bag strand 8.

Der Transportstreckenabschnitt 4 führt aus der Horizontalen in die Vertikale. Er umfaßt ein an der Bogeninnenseite angeordnetes Transportband 9, das unveränderlich durch eine nicht dargestellte Führung geführt wird. Auf der Bogenaußenseite ist ein zweites Transportband 10 vorgesehen, das am Anfang des Transportstrecken­abschnittes 4 über eine in der Höhe gegenüber dem Transportband 9 verstellbare Umlenkrolle 11 und am Ende des Transportstrecken­abschnittes 4 über der Stapelstelle 1 über ein nicht näher darge­stelltes Umlenkelement 12, das eine geringe Höhe hat und in Band­laufrichtung verstellbar ist, geführt ist. Zwischen der Umlenk­rolle 11 und dem Umlenkelement 12 erhält das Band seine Führung durch das an nicht dargestellten Stau- und Führungsmitteln ab­ gestützte Band 9, indes es sich auf diesem Band 9, unter Ein­klemmen der im Förderstreckenabschnitt 4 geförderten Beutel 13, abstützt. Das Band 10 läuft über weitere Umlenkrollen 14 bis 17, von denen die Umlenkrolle 17 mittels einer nicht dargestellten Feder das Band 10 unter Spannung hält. Die Rolle 17 bildet den Bandspeicher.The transport route section 4 leads from the horizontal to the vertical. It comprises a conveyor belt 9 arranged on the inside of the sheet, which is guided invariably by a guide, not shown. On the outside of the sheet, a second conveyor belt 10 is provided, which at the beginning of the transport section 4 via a deflection roller 11 which is adjustable in height relative to the conveyor belt 9 and at the end of the transport section 4 above the stacking point 1 via a deflection element 12, not shown, which is of low height has and is adjustable in the tape running direction, is guided. Between the deflecting roller 11 and the deflecting element 12, the band is guided by the accumulation and guiding means, not shown supported belt 9, meanwhile it is supported on this belt 9 by clamping the bags 13 conveyed in the conveyor section 4. The belt 10 runs over further deflection rollers 14 to 17, of which the deflection roller 17 holds the belt 10 under tension by means of a spring (not shown). The roll 17 forms the tape storage.

Das Ende des Bandes 10 reicht bis in den Karton 1 hinein. Gegen den Karton 1 wirkt in Richtung des Pfeils 18 eine Kraft, z. B. die Reibkraft des auf einer Unterlage abgestützten Kartons 1, die aber ein Zurückweichen (verschieben auf der Unterlage) des Kar­tons 1 entgegen der Richtung des Kraftpfeils zuläßt.The end of the tape 10 extends into the box 1. A force acts against the carton 1 in the direction of arrow 18, e.g. B. the frictional force of the carton 1 supported on a base, but which allows a retreat (move on the base) of the carton 1 against the direction of the force arrow.

Das Füllen des Kartons 1 erfolgt auf folgende Art und Weise:The box 1 is filled in the following way:

Die einzeln in Reihe hintereinander und flachliegend bei gleich­mäßig verteiltem Füllgut ankommenden Flachbeutel 6 werden beim Übergang auf die Förderstrecke 3 wegen der geringeren Förderge­schwindigkeit, wie bereits erläutert, geschuppt. Dadurch wird die Durchsatzleistung nicht vermindert, wohl aber die Transportge­schwindigkeit.The flat bags 6 arriving one after the other in a row and lying flat with evenly distributed filling material are shingled at the transition to the conveyor path 3 because of the lower conveying speed, as already explained. This does not reduce the throughput, but it does reduce the transport speed.

Nach einer bestimmten Anzahl von Beuteln 6, die beispielsweise in einen Karton 1 hineinpassen, wird das Band 7 beschleunigt, so daß der Beutelstrang 8 durch Bildung einer Lücke von dem näch­sten Beutelstrang abgesetzt wird. Sobald der Beutelstrang 8 in den abschüssigen Förderstreckenabschnitt 4 gelangt, werden die Beutel von den beiden Bändern 9, 10 beidseitig eingeklemmt. Da­durch erhalten sie auch auf der abschüssigen Förderstrecke eine definierte Fördergeschwindigkeit. Ferner wird dadurch gewähr­leistet, daß die gleichmäßige Verteilung des Füllgutes in den Beuteln erhalten bleibt. Dieses Eingeklemmtsein der Beutel geht auch dann nicht verloren, wenn der einzelne Beutel aus dem Wir­kungsbereich des Bandes 9 gerät, weil beim ersten Beutel die Stirnwand des Kartons 1 die Führung übernimmt und dann die weiteren, geschuppten Beutel. Die Beutel 13 werden auch nach Verlassen des Bandes 9 mit definierter Fördergeschwindigkeit ge­fördert, weil sie bis zum Erreichen ihrer Endlage unter der Wir­kung des zweiten Förderbandes 10 stehen. Da das zweite Förder­band 10 nicht nachgiebig abgestützt ist, üben die in den Karton 1 geförderten Beutel einen der Kraftrichtung 18 entgegengerichte­ten Druck aus, so daß der Behälter mit dem Fortschritt der Fül­lung gegen die in Richtung des Pfeils 18 wirkende Kraft auf sei­ner Unterlage verschoben wird. Im einfachsten Fall kann der Kar­ton auf einer Gleitbahn abgestellt sein, so daß der Druck aus­reichen muß, um den Karton 1 in Bewegung zu setzen. Reicht der Druck nicht aus, oder würde der Druck für das Füllgut zu groß sein, kann auf den Behälter zusätzlich eine in Bewegungsrichtung wirkende Kraft ausgeübt werden.After a certain number of bags 6, which fit, for example, into a carton 1, the belt 7 is accelerated, so that the string of bags 8 is separated from the next string of bags by forming a gap. As soon as the bag strand 8 reaches the downward conveyor section 4, the bags are clamped on both sides by the two belts 9, 10. This gives them a defined conveying speed even on the downhill conveyor. This also ensures that the even distribution of the contents in the bags is maintained. This jammed bag is going also not lost if the individual bag comes out of the effective range of the belt 9, because in the first bag the end wall of the carton 1 takes the lead and then the other, flaky bags. The bags 13 are also conveyed at a defined conveying speed after leaving the belt 9 because they are under the action of the second conveyor belt 10 until they have reached their end position. Since the second conveyor belt 10 is not resiliently supported, the bags conveyed into the carton 1 exert a pressure opposing the direction of force 18, so that the container is displaced on its support as the filling advances against the force acting in the direction of arrow 18. In the simplest case, the box can be placed on a slideway, so that the pressure must be sufficient to set the box 1 in motion. If the pressure is not sufficient or if the pressure for the contents would be too high, a force acting in the direction of movement can also be exerted on the container.

Sobald der Karton 1 mit Flachbeuteln gefüllt ist, wird die Lücke zwischen zwei aufeinanderfolgenden Strängen 8, 13 ausgenutzt, um das Umlenkelement 12 aus dem Karton 1 herauszuziehen und in den nachfolgenden Verpackungsbehälter wieder einzuführen.As soon as the carton 1 is filled with flat bags, the gap between two successive strands 8, 13 is used to pull the deflecting element 12 out of the carton 1 and reinsert it into the subsequent packaging container.
