Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Öffnen vorgefertigter (Schlauch-)Beutelverpackungen ("Pouches") sowie ein Verfahren und eine Vorrichtung zum Füllen vorgefertigter (Schlauch-)Beutelverpackungen, welches ein Verfahren bzw. welche eine Vorrichtung zum Öffnen derartiger Beutelverpackungen einschließt.The invention relates to a method and a device for opening prefabricated (Hose) pouch packaging ("pouches") and a method and a device for Filling prefabricated (tubular) bag packaging, which is a process or which includes a device for opening such pouch packs.

Aus zahlreichen Gründen, die beispielsweise Überlegungen zur Materialeinsparung und Umweltgesichtspunkte, aber auch Kosteneinsparungen betreffen, bemüht man sich heute vielfach darum, die bisher in großem Umfang eingesetzten (Weißblech-)Dosen durch Beutelverpakkungen zu ersetzen, die mit wesentlich geringerem Materialeinsatz hergestellt werden können.For numerous reasons, such as considerations about material savings and environmental considerations, However, efforts are often made to cut costs today therefore, the (tinplate) cans previously used on a large scale through bag packaging to replace, which can be manufactured with significantly less material.

Der Grund dafür, daß sich derartige Beutelverpackungen bisher nur zögernd und im wesentlichen nur in Fällen durchgesetzt haben, bei denen die zu verpackenden Mengen sehr klein sind, liegt hauptsächlich darin, daß die Handhabung vorgefertigter Beutelverpackungen unter Beibehaltung einer bestimmten Form (Formstabilität) mit Schwierigkeiten verbunden ist, was insbesondere für den Schritt des Öffnens gilt, der dem Füllen und Versiegeln vorgeordnet ist.The reason why such bag packaging has so far been only hesitant and essentially only in cases where the quantities to be packaged are very small are mainly due to the fact that the handling of prefabricated bag packaging is under Maintaining a certain shape (dimensional stability) is difficult with what applies in particular to the opening step, which precedes filling and sealing.

Bei einer Anlage nach dem Stand der Technik erfolgt die Öffnung vorgefertigter, in ebener Form vorliegender Beutelverpackungen, die meist rechteckig sind und eine umlaufende Versiegelung und eine Öffnungszone aufweisen, dadurch, daß eine Beutelverpackung bzw. Pouch an ihren beiden der Öffnungszone benachbarten Seitenkanten mit Greifern erfaßt wird, die sich dann um ein bestimmtes Maß aufeinander zu bewegen, so daß die Beutelverpackung geöffnet wird. Dieses Verfahren ist in doppelter Hinsicht nachteilig. Einerseits ist das Öffnen eines Beutels durch Zusammenbewegen der Seitenkanten nur bei relativ kleinen Abmessungen möglich, da sich der Beutel ansonsten lediglich durchbiegt, ohne sich zu öffnen, und andererseits der Beutel aufgrund der Elastizität der Versiegelungsnähte nur zu einem relativ geringen Grad geöffnet wird, was zu einer entsprechend geringen maximalen Füllmenge führt.In a system according to the state of the art, the opening takes place in a prefabricated manner Form of existing pouch packaging, which is mostly rectangular and a circumferential seal and have an opening zone in that a bag packaging or Pouch is gripped on both of its side edges adjacent to the opening zone with grippers, which then move towards each other by a certain amount, so that the bag packaging is opened. This process is disadvantageous in two respects. On the one hand is opening of a bag by moving the side edges together only with relatively small dimensions possible, because otherwise the bag only bends without opening, and on the other hand the bag only relative to one due to the elasticity of the sealing seams is opened to a small degree, resulting in a correspondingly low maximum filling quantity leads.

Aus der EP 0 844 179 ist ein Verfahren und eine Vorrichtung zum Öffnen vorgefertigter Beutel bekannt, wobei das Öffnen der Beutel mit Unterdruckkammern erfolgt, die aus zwei trennbaren Halbschalen gebildet sind und im geschlossenen Zustand an der oberen Stirnfläche eine Öffnung aufweisen, an deren Ränder sich der geöffnete Beutel anlegt. Zur Halterung der Beutel dienen ortsfeste Schienen, die auch die Öffnung der Stirnfläche abdecken. Bei dieser bekannten Vorrichtung werden nur stehfähige Seitenfaltenbeutel und keine (Schlauch-) Beutelverpackungen geöffnet und gefüllt. Letztere bedürfen einer speziellen Halterung.EP 0 844 179 describes a method and a device for opening prefabricated ones Bags known, the opening of the bags with vacuum chambers, which consists of two separable half-shells are formed and in the closed state on the upper end face have an opening, at the edges of which the opened pouch bears. To hold the Bags are used for stationary rails, which also cover the opening of the end face. At this known device are only standing gusseted bags and no (tube) Bag packaging opened and filled. The latter require a special bracket.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, ein Verfahren und eine Vorrichtung zum Öffnen vorgefertigter Beutelverpackungen anzugeben, mit dem bzw. der die genannten Nachteile überwunden werden und unbeschränkt große Beutelverpackungen sicher geöffnet werden können und insbesondere wesentlich weiter geöffnet werden, als dies beim Stand der Technik der Fall ist.The object of the present invention is therefore a method and an apparatus to indicate the opening of prefabricated bag packaging with which the mentioned disadvantages are overcome and unlimited large bag packaging safely can be opened and in particular can be opened much wider than when State of the art is the case.

For example, a Partition plane can be arranged essentially in the plane of the bag packaging 5, or but perpendicular to it, i.e. essentially in the representation plane of FIG. 2.

    Wie in Fig. 2 weiter angedeutet ist, weist die im wesentlichen zylindrische Unterdruckkammer 8 an ihrer oberen (oberhalb der Darstellungsebene der Fig. 2) Stirnfläche eine Öffnung 9 auf deren Berandungslinie im wesentlichen der Querschnittsform des Trägers 1 entspricht, bzw. auf der vom Träger 1 aus gesehen gegenüberliegenden Seite der Beutelverpackung 5 entsprechend ergänzt ist.As is further indicated in Fig. 2, the substantially cylindrical vacuum chamber 8 has an opening 9 on its upper end face (above the representation plane of FIG. 2) on the edge line of which essentially corresponds to the cross-sectional shape of the carrier 1, or on the opposite side of the bag packaging 5 as seen from the carrier 1 is supplemented accordingly.

    Fig. 5 dient zur weiteren Erläuterung der Unterdruckkammer 8, die in diesem Beispiel aus zwei vertikal geteilten Halbschalen 12, 13 besteht, zwischen denen der Träger 1 für die (nicht dargestellte) Beutelverpackung aufgenommen ist.Fig. 5 serves to further explain the vacuum chamber 8, which in this example two vertically divided half-shells 12, 13, between which the carrier 1 for the (not shown) bag packaging is included.

    Fig. 3 zeigt eine Ansicht entsprechend Fig. 2, wobei die Beutelverpackung 5 vollständig geöffnet ist. Man erkennt, daß der erste, ortsfest gehaltene Seitenrand 7 der Beutelverpackung seine Stellung unverändert beibehalten hat, während sich der zweite Seitenrand 6 in Richtung auf den ersten Seitenrand bewegt hat, um die Öffnung bzw. Aufweitung des Beutels auszugleichen. Wie weiter aus Fig. 3 ersichtlich ist, hat sich der Beutel 5 mit seiner einen Hälfte vollflächig gegen den entsprechend geformten Träger 1 angelegt und liegt andererseits, wie man aus der perspektivischen Darstellung nach Fig. 5 entnehmen kann, mit seinem oberen Rand weitgehend gegen den Rand der ersten Öffnung 9 an. Wie ferner aus Fig. 5 ersichtlich ist, bilden die beiden Halbschalen 12, 13 der Unterdruckkammer 8 eine der ersten Öffnung 9 gegenüberliegende zweite Öffnung 10.FIG. 3 shows a view corresponding to FIG. 2, the bag packaging 5 being fully opened is. It can be seen that the first, stationary side edge 7 of the bag packaging has maintained its position unchanged, while the second side edge 6 in the direction has moved to the first side edge to compensate for the opening or expansion of the bag. As can further be seen from FIG. 3, the bag 5 has one half fully applied against the correspondingly shaped carrier 1 and on the other hand, how can be seen from the perspective view of FIG. 5, with its upper Edge largely against the edge of the first opening 9. As can also be seen from FIG. 5 , the two half-shells 12, 13 of the vacuum chamber 8 form one of the first opening 9 opposite second opening 10.

    Fig. 4 schließlich zeigt eine Ansicht entsprechend Fig. 1, wobei die beiden Halbschalen 12, 13 der Unterdruckkammer 8 wieder entfernt bzw. auseinandergefahren sind und die Beutelverpackung 5 ihre offene, aufgeweitete Form einnimmt, unterstützt durch die Halterung ihrer beiden Seitenränder 6, 7 an den entsprechenden Auflageflächen des Trägers 1. FIG. 4 finally shows a view corresponding to FIG. 1, the two half-shells 12, 13 the vacuum chamber 8 are removed or moved apart and the bag packaging 5 assumes its open, expanded shape, supported by the support of its two side edges 6, 7 on the corresponding contact surfaces of the carrier 1.

    Nachfolgend sei die Funktion der erfindungsgemäßen Vorrichtung erläutert. Nachdem der in Fig. 2 dargestellte Zustand erreicht ist, d.h., nachdem sich die Unterdruckkammer 8 um die auf dem Träger 1 gehaltene Beutelverpackung 5 geschlossen hat, wird eine Unterdruckquelle bzw. Absaugeeinrichtung an die untere, d.h. der Öffnungszone der Beutelverpackung gegenüberliegende bzw. zweite Öffnung 10 angeschlossen. Aufgrund des Strömungswiderstands der Luft durch die erste Öffnung 9 in die Unterdruckkammer bildet sich in dieser bereits ein leichter Unterdruck, während eine der Absaugung entsprechende Zuströmung durch die Öffnung 9 erfolgt, d.h. auftreffend auf den (noch) geschlossenen Rand der Beutelverpackung im Bereich der Örfnungszone.The function of the device according to the invention will be explained below. After the in 2 is reached, i.e. after the vacuum chamber 8 is around the has closed bag package 5 held on the carrier 1 becomes a vacuum source or suction device to the lower, i.e. opposite the opening zone of the bag packaging or second opening 10 connected. Because of the flow resistance the air through the first opening 9 into the vacuum chamber already forms in the latter slight negative pressure, while an inflow corresponding to the suction through the opening 9 takes place, i.e. hitting the (still) closed edge of the bag packaging in the Area of the opening zone.

    Das Zusammenwirken eines leichten Unterdrucks auf den Seitenflächen der Beutelverpakkung mit einer auf die Öffnungszone auftreffenden Luftströmung führt zu einer allmählichen Öffnung der Beutelverpackung. Diese Öffnungsbewegung setzt sich beschleunigt fort, da die erste Öffnung 9, durch die die Umgebungsluft in die Unterdruckkammer 8 nachströmt, aufgrund der zunehmenden Öffnung der Beutelverpackung zunehmend verschlossen wird. Schließlich wird der in Fig. 3 dargestellte Endzustand erreicht, in dem der obere Rand der Beutelverpackung 5 im Bereich von deren Öffnungszone weitgehend gegen den Rand der ersten Öffnung 9 anliegt und damit den freien Strömungsquerschnitt für in die Unterdruckkammer 8 einströmende Umgebungsluft ganz wesentlich verkleinert. Aufgrund der weiterhin erfolgenden Absaugung aus der zweiten Öffnung 10 stellt sich daher ab diesem Punkt, d.h. ab dem Anliegen des oberen Rands der Beutelverpackung gegen die erste Öffnung 9, ein zunehmender Unterdruck innerhalb der Unterdruckkammer 8 ein. Dieser Unterdruck führt dazu, daß die Beutelverpackung 5 soweit aufgeweitet wird, wie dies ohne Zerstörung der umlaufenden Versiegelung im Bereich der Seiten- und Bodenkanten möglich ist. Dabei bewegt sich der erste, beweglich gehaltene Seitenrand 6 der Beutelverpackung so weit auf den zweiten, ortsfest gehaltenen Seitenrand 7 zu, wie dies für die Aufweitung erforderlich ist.The interaction of a slight negative pressure on the side surfaces of the bag packaging with an air flow hitting the opening zone leads to a gradual one Opening the bag packaging. This opening movement is accelerated because the first opening 9, through which the ambient air flows into the vacuum chamber 8, due to the increasing opening of the bag packaging is increasingly closed. Finally, the final state shown in Fig. 3 is reached, in which the upper edge of the Bag packaging 5 in the area of its opening zone largely against the edge of the first opening 9 abuts and thus the free flow cross section for in the vacuum chamber 8 inflowing ambient air significantly reduced. Because of the continued Suction taking place from the second opening 10 therefore arises from this point, i.e. from the concern of the upper edge of the bag packaging against the first opening 9, an increasing Vacuum inside the vacuum chamber 8. This negative pressure leads to that the bag package 5 is expanded as far as this without destroying the rotating Sealing in the area of the side and bottom edges is possible. The moves first, movable side edge 6 of the bag packaging so far on the second, stationary held side edge 7 to, as is necessary for the expansion.

    Die starke Aufweitung der Beutelverpackung hat die Vorteile, daß einerseits ein maximales Fassungsvermögen erzielt wird, d.h., daß ein gegebener Beutel mit einer maximalen Befüllungsmenge gefüllt werden kann, und daß andererseits aufgrund einer gewissen plasrischen Verformung im Versiegelungsbereich diese aufgeweitete Form eine Zeit lang von selbst aufrechterhalten bleibt, d.h. mindestens bis zum anschließendsn Füllungsvorgang. The strong expansion of the bag packaging has the advantages that on the one hand a maximum Capacity is achieved, i.e. a given bag with a maximum filling quantity can be filled, and that, on the other hand, due to a certain plastic Deformation in the sealing area maintain this expanded shape for a while by itself remains, i.e. at least until the subsequent filling process.

    Fig. 6 zeigt in einer schematischen Draufsicht einen Ausschnitt aus einer Anlage zum Öffnen. Füllen und Verschließen (Versiegeln) vorgefertigter Beutelverpackungen, wobei der Öffnungsvorgang in erfindungsgemäßer Weise ausgeführt wird. Die Anlage weist eine kontinuierliche Fördereinrichtung 2 auf, an der in regelmäßigen Abständen eine Vielzahl von Trägern 1 angebracht ist. Die in Richtung des Pfeils 15 kontinuierlich umlaufende Fördereinrichtung 2 nimmt an einer Eingabestation 16 in Richtung des Pfeils 17 eintreffende, vorgefertigte Beutelverpackungen auf, die entweder von einem entsprechenden Vorrat oder unmittelbar von einer Beutel-Herstellungsmaschine kommen können, worauf diese an einer Öffnungsstation 18 geöffnet werden. Die geöffneten Beutelverpackungen 5, die jeweils auf einem Träger 1 gehalten sind, gelangen zu einer nicht dargestellten Füllstation und anschließend an eine lediglich angedeutete Siegelstation 21, an der die Öffnungszone bzw. der obere Rand der Beutel verschlossen wird. Die gefüllten und verschlossenen Beutelverpackungen werden schließlich an einer Ausgabestation 22 in Richtung des Pfeils 23 abgegeben.Fig. 6 shows a schematic plan view of a section of a system for opening. Filling and closing (sealing) prefabricated bag packaging, the opening process is carried out according to the invention. The plant exhibits a continuous Conveyor 2 on which a variety of carriers at regular intervals 1 is attached. The conveyor device 2, which rotates continuously in the direction of arrow 15 takes prefabricated bag packs arriving at an input station 16 in the direction of arrow 17 on either from a corresponding stock or directly from a bag-making machine can come, whereupon this at an opening station 18 can be opened. The opened bag packs 5, each on a carrier 1 are held, reach a filling station, not shown, and then only one indicated sealing station 21, at which the opening zone or the upper edge of the bag is closed. The filled and closed pouch packaging will eventually dispensed at an output station 22 in the direction of arrow 23.

    Die Öffnungsstation 18 ist in erfindungsgemäßer Weise so ausgebildet, daß über eine gewisse Lauflänge hinweg eine Unterdruckkammer um jede einzelne zugeführte Beutelverpackung gebildet wird. Hierzu ist eine zweite Fördereinrichtung 24 vorgesehen, die innerhalb des Öffnungsbereichs eng benachbart zur ersten Fördereinrichtung 2 verläuft, wobei Bewegungsrichtung und Geschwindigkeit der aneinanderliegenden Bereiche miteinander übereinstimmen (Pfeil 25). Die zweite Fördereinrichtung 24 ist in regelmäßigen Abständen mit Halbschalen 12 versehen, die mit in Fig. 6 nicht im einzelnen dargestellten, entsprechenden Halbschalen 13 zusammenwirken, die auf der Fördereinrichtung 2 angebracht sind, so daß innerhalb des Bereichs, in dem die Fördereinrichtung 24 eng benachbart zur Fördereinrichtung 2 verläuft, Unterdruckkammern 8 gebildet werden, wie dies in Fig. 5 angedeutet ist. Weiterhin wird die durch die beiden Halbschalen 12, 13 gebildete untere Öffnung 10 der Unterdruckkammer 8 innerhalb des Öffnungsbereichs in geeigneter Weise mit einer Unterdruckquelle bzw. Absaugeeinrichtung in Verbindung gebracht, so daß der vorstehend unter Bezugnahme auf Fig. 1 bis 5 erläuterte Öffnungsvorgang der Beutelverpackungen ausgeführt wird. Am Ende des Öffnungsbereichs 18 trägt die Fördereinrichtung 2 somit vollständig geöffnete Beutelverpakkungen 5, die jeweils an Trägern 1 gehalten sind. The opening station 18 is designed according to the invention so that over a certain A vacuum chamber runs around the length of each individual bag package is formed. For this purpose, a second conveyor device 24 is provided, which is within the opening area runs closely adjacent to the first conveyor 2, with the direction of movement and the speed of the adjacent areas coincide with each other (Arrow 25). The second conveyor 24 is at regular intervals with half-shells 12 provided with the corresponding half-shells not shown in detail in FIG. 6 13 cooperate, which are attached to the conveyor 2, so that within the Area in which the conveyor device 24 runs closely adjacent to the conveyor device 2, Vacuum chambers 8 are formed, as indicated in Fig. 5.
