Description

Die vorliegende Erfindung betrifft eine vertikale Schlauchbeutelmaschine mit einem Zuführsystem für einen die Schlauchbeutel bildenden Hüllstoff, einem Füllrohr, um das der Hüllstoff zur Bildung eines Schlauches geführt wird und das zur Einfüllung des zu verpackenden Materiales dient, einer Längsnahtschweißvorrichtung, einer Quernahtschweißvorrichtung zur Ausbildung einer unteren und einer oberen Querschweißnaht an einem Schlauchbeutel, einer Hebevorrichtung für den gefüllten, noch nicht mit der oberen Querschweißnaht versehenen Schlauchbeutel und einer unterhalb der Quernahtschweißvorrichtung vorgesehenen Faltvorrichtung mit zwei Faltorganen für den Hüllstoff am oberen Schlauchbeutelendbereich.The present invention relates to a vertical tubular bag machine with a feed system for one Tubular bag-forming envelope, a filling tube to the the envelope is led to form a tube and that serves to fill in the material to be packed, a longitudinal seam welding device, a transverse seam welding device to form a lower and an upper Cross weld seam on a tubular bag, a lifting device for the filled, not yet with the upper cross weld provided tubular bag and one below the folding device provided for the transverse seam welding device with two folding elements for the wrapping material at the upper end of the tubular bag.

Eine derartige vertikale Schlauchbeutelmaschine ist aus der DE 195 47 860 C2 bekannt. Bei der bekannten Schlauchbeutelmaschine ist die Faltvorrichtung relativ zur Vorrichtung zur Erzeugung der Querschweißnähte auf- und abbewegbar, und die Hebevorrichtung und die Faltvorrichtung sind so gesteuert angetrieben, daß die Faltvorrichtung und der gefüllte Schlauchbeutel zum Falten des Hüllstoffes auf die Füllgutoberfläche relativ zur Vorrichtung zur Erzeugung der Querschweißnähte und zum Füllrohr angehoben werden. Zum Falten des Hüllstoffs auf die Füllgutoberfläche führen somit die Hebevorrichtung und die Faltvorrichtung gemeinsam eine Aufwärtsbewegung durch. Hierdurch wird erreicht, daß der Hüllstoff eng auf die Füllgutoberfläche umgelegt werden kann, so daß nahezu kein Luftraum mehr über der Füllgutoberfläche verbleibt. Die obere Querschweißnaht kann daher in einem besonders geringen Abstand von der Füllgutoberfläche angeordnet werden.Such a vertical tubular bag machine is from the DE 195 47 860 C2 known. In the known tubular bag machine is the folding device relative to the device can be moved up and down to produce the transverse weld seams, and the lifting device and the folding device are controlled in this way driven that the folding device and the filled Tubular bag for folding the wrapping material onto the product surface relative to the device for generating the Cross welds and to the filling pipe are raised. To the Folding the wrapping material on the product surface thus leads the lifting device and the folding device together an upward move through. This ensures that the wrapping material is placed tightly on the product surface can be, so that almost no airspace over the Product surface remains. The upper cross weld can therefore at a particularly short distance from the Product surface can be arranged.

Es sind ferner bereits vertikale Schlauchbeutelmaschinen bekannt (DD 114 040), die eine Hebevorrichtung zum Anheben des gefüllten, noch nicht mit der oberen Querschweißnaht versehenen Schlauchbeutels aufweisen, um durch Anheben des Schlauchbeutels eine Gewichtsentlastung der Schweißnaht zu erreichen. Bei dieser bekannten Maschine wird der Schlauch,wenn sich die Schweißbacken der Schweißlage nähern, einem Vakuum ausgesetzt, so daß sich der Hüllstoff eng um den Füllstoff schmiegt.There are also vertical tubular bag machines known (DD 114 040), which is a lifting device for lifting of the filled, not yet with the upper cross weld provided tubular bag to by lifting the Tubular bag relieves the weight of the weld to reach. In this known machine Hose when the welding jaws approach the welding position, exposed to a vacuum so that the envelope hugs the filler tightly.

Der Erfindung liegt die Aufgabe zugrunde, eine vertikale Schlauchbeutelmaschine der eingangs beschriebenen Art zu schaffen, die auf besonders einfache und kostengünstige Weise ein Umfalten des Hüllstoffes auf die Füllgutoberfläche im Schlauchbeutel unter Herausdrücken der Luft in diesem Bereich ermöglicht.The invention has for its object a vertical Tubular bag machine of the type described at the beginning create that on particularly simple and inexpensive How to fold the wrapping material onto the product surface in the tubular bag while pushing the air out enables this area.

Diese Aufgabe wird erfindungsgemäß bei einer Maschine der angegebenen Art dadurch gelöst, daß die Faltvorrichtung vertikal unbeweglich angeordnet ist und die Hebevorrichtung und die Faltvorrichtung so gesteuert angetrieben sind, daß zum Falten des Hüllstoffes auf die Füllgutoberfläche der gefüllte Schlauchbeutel relativ zur Faltvorrichtung angehoben und die beiden Faltorgane der Faltvorrichtung horizontal einwärts bewegt werden, derart, daß der Hüllstoff zwischen den Faltorganen und der Füllgutoberfläche geführt straff gehalten wird. This object is achieved according to the invention in a machine specified type solved in that the folding device is arranged vertically immovably and the lifting device and the folding device are driven so controlled that for folding the wrapping material onto the product surface filled tubular bag raised relative to the folding device and the two folding members of the folding device horizontally be moved inwards such that the envelope between the folding organs and the product surface is kept taut.

Bei der erfindungsgemäßen Lösung wird somit lediglich die Hebevorrichtung und damit der gefüllte Schlauchbeutel in Vertikalrichtung bewegt, während die Faltvorrichtung ausschließlich horizontal bewegt wird. Es wurde festgestellt, daß eine Vertikalbewegung der Faltvorrichtung zum Umfalten des Hüllstoffs nicht unbedingt erforderlich ist, wenn das Ausdrücken der Luft in diesem Bereich des Schlauchbeutels im Vordergrund steht und weniger Wert auf die Qualität der Faltung gelegt wird. Die Faltvorrichtung muß daher lediglich in Horizontalrichtung bewegt werden, wobei gleichzeitig mit der Hubbewegung des Schlauchbeutels die beiden Faltorgane der Faltvorrichtung horizontal einwärts bewegt werden, so daß der Hüllstoff zwischen den Faltorganen und der Füllgutoberfläche geführt straff gehalten wird. Nach Beendigung der Hubbewegung des Schlauchbeutels haben beide Faltorgane ihre innerste Endstellung erreicht, wobei in diesem Zustand der Hüllstoff straff an der Füllgutoberfläche anliegt. Es kann dann die obere Querschweißnaht erzeugt werden.In the solution according to the invention, only the Lifting device and thus the filled tubular bag in Moves vertically while the folding device only is moved horizontally. It was determined, that a vertical movement of the folding device for folding of the coating material is not absolutely necessary, if that Express the air in this area of the tubular bag is in the foreground and less emphasis on the quality of the Folding is laid. The folding device must therefore only be moved in the horizontal direction, whereby at the same time as the lifting movement of the tubular bag two folding members of the folding device horizontally inwards be moved so that the envelope between the Folding organs and the surface of the product are tight is held. After the lifting movement of the Tubular bags have both folding organs at their innermost End position reached, in this state the envelope is tight against the product surface. Then it can upper cross weld.

Durch das Einwärtsbewegen der beiden Faltorgane bei gleichzeitigem Anheben des Schlauchbeutels wird der zur Verfügung gestellte Hüllstoff eng und straff an die Füllgutoberfläche gedrückt, wobei die sich in diesem Bereich des Schlauchbeutels befindliche Luft herausgedrückt wird. Es verbleibt daher kein Luftpolster unterhalb der oberen Querschweißnaht.By moving the two folding organs inwards at the same time Lifting the tubular bag becomes available placed wrapping material tightly and tightly on the product surface pressed, which is in this area of the tubular bag air is pushed out. It remains therefore no air cushion below the upper cross weld.

Die erfindugsgemäß vorgeschlagene Lösung, bei der die Faltvorrichtung während des Betriebes nicht angehoben wird, hat gegenüber der aus der DE 195 47 860 C2 bekannten Lösung insofern gewisse Nachteile, als daß hiermit keine besonders hohe Qualität der Faltung erreicht wird, d.h. es wird kein absolut spannungsfreies Einwärtsfalten des Hüllstoffes erzielt. Demgegenüber ist jedoch die Maschine einfacher ausgebildet und somit kostengünstiger.The solution proposed according to the invention, in which the folding device has not been lifted during operation compared to the solution known from DE 195 47 860 C2 certain disadvantages in that none of them are special high quality of folding is achieved, i.e. it won't achieved absolutely tension-free inward folding of the wrapping material. In contrast, the machine is simpler and therefore cheaper.

Die Quernahtschweißvorrichtung kann bei dieser Ausführungsform in herkömmlicher Form ausgebildet sein, beispielsweise als Einheit zur Ausbildung der unteren und oberen Querschweißnaht. Beide Querschweißnähte können jedoch auch von getrennten Vorrichtungen gebildet werden.The cross seam welding device can in this embodiment be formed in a conventional form, for example as a unit for the formation of the lower and upper cross weld seam. However, both cross welds can also be formed by separate devices.

Zweckmäßigerweise ist die Faltvorrichtung an der Quernahtschweißvorrichtung befestigt. Dabei sind insbesondere die Führungen der Faltorgane der Faltvorrichtung an den Schweißbackenträgern der Quernahtschweißvorrichtung fixiert. Mit dieser Ausführungsform führen somit die Schweißbacken und die beiden Faltorgane eine gemeinsame Einwärts- und Auswärtsbewegung durch. Wenn die Faltorgane ihre innere Endstellung erreichen und damit die Luft vollständig abgedrückt ist, haben auch die Schweißbacken ihre Schweißstellung erreicht, so daß der Schweißvorgang beginnen kann.The folding device on the transverse seam welding device is expedient attached. In particular, the Guides of the folding organs of the folding device on the Welding jaw carriers of the transverse seam welding device fixed. With this embodiment, the welding jaws lead and the two folding organs a common inward and Outward movement by. If the folding organs their inner Reach the end position and thus completely exhaust the air the welding jaws also have their welding position reached so that the welding process can begin.

Wie erwähnt, ist die Faltvorrichtung vertikal unbeweglich angeordnet. Dies erfährt jedoch vorzugsweise insofern eine Ausnahme, als daß die Faltvorrichtung in Anpassung an geringere Füllstandsschwankungen im Schlauchbeutel vertikal verstellbar ist, und zwar relativ zur Querschweißnahtvorrichtung. Diese Verstellung kann manuell oder automatisch erfolgen. Eine derartige Verstellbarkeit hat jedoch nichts mit der vertikalen Unbeweglichkeit im Betrieb der Maschine zu tun.As mentioned, the folding device is immovable vertically arranged. However, this is preferably experienced in so far Exception than that the folding device in adaptation to less Level fluctuations in the tubular bag vertically is adjustable, namely relative to the cross weld device. This adjustment can be done manually or automatically respectively. However, such adjustability has nothing with the vertical immobility in the operation of the machine to do.

Vorzugsweise wird die Hebevorrichtung über eine Strecke angehoben, die etwa der Breite des Schlauchbeutels entspricht. Dadurch wird eine solche Länge Hüllmaterial zur Verfügung gestellt, wie sie für das Umfalten des Hüllmateriales auf die Füllgutoberfäche über die Breite des Schlauchbeutels benötigt wird, wobei natürlich von jeder Seite unterhalb der Schweißbacke nur etwa der halben Breite des Schlauchbeutels entsprechendes Hüllmaterial umgefaltet wird. Dadurch wird durch das Anheben exakt soviel Hüllmaterial zur Vefügung gestellt, wie für das Umfalten eng anliegend am Füllgut benötigt wird.The lifting device is preferably raised over a distance, which corresponds approximately to the width of the tubular bag. This makes such a length of wrapping material Provided for folding the wrapping material on the product surface across the width of the Tubular bag is required, of course by everyone Side below the welding jaw only about half the width of the tubular bag corresponding envelope material folded becomes. As a result, exactly as much is achieved by lifting Envelope material provided, as for folding close fitting to the filling material is required.

Während der Faltbewegung des Hüllstoffes kann auch zusätzlich Hüllstoft zugeführt werden. Hierdurch wird eine Reduzierung des Hubs der Hebevorrichtung erreicht. Dies ist bei der Steuerung der Bewegungen der Hebevorrichtung zu berücksichtigen.In addition, during the folding movement of the wrapping material Hüllstoft be fed. This will result in a reduction of the stroke of the lifting device. This is at the control of the movements of the lifting device.

Bei unbedrucktem Hüllstoff können geringe Füllstandsschwankungen auch mit dem Hüllstoffabzug ausgeglichen werden.With unprinted wrapping material, slight level fluctuations can occur can also be compensated for with the deduction of enveloping material.

Die Faltvorrichtung weist vorzugsweise zusätzlich zu den zwei Faltorganen Seitenfalter auf, die bei einem rechteckigen Schlauchbeutel ein Umfalten des Hüllstoffes auf den schmaleren Stirnseiten bewirken. Diese Seitenfalter können vorzugsweise in der Form eines Flachstückes ausgebildet sein.The folding device preferably has in addition to the two folding organs on side folders, which are rectangular Tubular bag a folding of the envelope on the cause narrower end faces. These side moths can preferably in the form of a flat piece his.

Die Quernahtschweißvorrichtung 3 besitzt zwei beidseitig des Füllrohres angeordnete Schweißbacken 13, von denen der Schweißbacken der linken Figurhälfte in der zurückgezogenen Stellung und der Schweißbacken in der rechten Figurhälfte in der einwärts bewegten Schweißstellung dargestellt sind. Die Schweißbacken 13 werden über ein geeignetes Hubsystem 5 einwärts und auswärts bewegt. Die Funktionsweise dieser Schweißbacken ist bekannt und stellt keinen Teil der vorliegenden Erfindung dar.At a short distance from the lower end of the filling pipe 1 a transverse seam welding device 3 is arranged. This is used to create an upper cross weld for one lower tubular bag and to produce a lower one Cross weld seam for an upper tubular bag. The Cross seam welding device 3 has two on both sides of the Filler tube arranged welding jaws 13, of which the Sweat jaws of the left half of the figure in the retracted Position and the welding jaws in the right half of the figure are shown in the inwardly moved welding position. The welding jaws 13 are moved using a suitable lifting system 5 moved in and out. How this works Welding jaws are known and do not form part of the present Invention.

Unterhalb der Quernahtschweißvorrichtung 3 befindet sich eine Faltvorrichtung 14, von der zwei weitere Organe 6 dargestellt sind, die sich beidseitig des Füllrohres 1 befinden. Die Faltorgane 6 sind an den Schweißbackenträgern befestigt, ebenfalls die Führungen für die vertikale Verstellung, so daß sich die Schweißbacken und Faltorgane bei der Betätigung der Hubeinrichtung 5 gemeinsam einwärts und auswärts bewegen. Figur 2 zeigt,daß die Faltvorrichtung 14 neben den Hauptfaltorganen 6 sogenannte Seitenfalter 11 aufweist, die den Hüllstoft an den Stirnseiten der Schlauchbeutel falten.Is located below the transverse seam welding device 3 a folding device 14, of which two further organs 6 are shown are, which are located on both sides of the filling tube 1. The folding members 6 are fastened to the welding jaw carriers, also the guides for the vertical Adjustment so that the welding jaws and folding organs when actuating the lifting device 5 together inwards and move out. Figure 2 shows that the folding device 14 in addition to the main folding members 6, so-called side folders 11 having the envelope on the end faces of the Fold the tubular bag.

Der am unteren Ende bereits mit einer Querschweißnaht versehene und mit Füllgut 8 befüllte Schlauchbeutel 12 ruht in einer Hebevorrichtung 9. Die Hebevorrichtung 9 besitzt wegklappbare Elemente, die in weggeklapptem Zustand ein Nachuntenfallen des fertigen Schlauchbeutels 12 ermöglichen.The one with a cross weld at the lower end and tubular bag 12 filled with filling material 8 rests in a lifting device 9. The lifting device 9 has foldable Elements that fall down when folded away enable the finished tubular bag 12.

Die Hebevorrichtung 9 ist mit einem Hubsystem 10 verbunden, das ein Anheben des Schlauchbeutels ermöglicht. Der linke Teil der Figur 1 zeigt die Hebevorrichtung im abgesenkten Zustand, während der rechte Teil die Hebevorrichtung im angehobenen Zustand zeigt. Dabei ist die Hebevorrichtung um eine Strecke angehoben, die etwa der Breite B des Beutels entspricht.The lifting device 9 is connected to a lifting system 10, that enables lifting of the tubular bag.

Der Seitenfalter 11 ist im einwärtsbewegten Zustand der Faltorgane 6 ebenfalls einwärts bewegt, und zwar derart, daß das Hüllmaterial seitlich um den Betrag B/2 nach innen gefaltet worden ist.Figure 2 shows a plan view of the folding device, wherein in the upper part the main folding organs 6 in their retracted outer position are shown, while the lower Part of the figure shows the folding organs 6 in the inward position. The Side folder 11 is in the inwardly moved state of the folding members 6 also moved inward, in such a way that the Envelope material folded inwards by the amount B / 2 has been.

Die Maschine funktioniert in der folgenden Weise:The machine works in the following way:

Nach dem Auffüllen des Schlauchbeutels 12 mit Füllgut 8 (auch dieser Zustand ist im linken Teil der Figur 1 gezeigt) beginnt die Hubeinrichtung 10 die Hebevorrichtung 9 zu heben. In Verbindung mit dieser Hubbewegung bewegen sich die beiden Schweißbacken 13 zusammen mit den beiden Faltorganen 6 horizontal nach innen, d.h in Richtung auf die Beutelachse. Durch das Anheben des gefüllten Schlauchbeutels 12 wird zusätzlicher Hüllstoff im Bereich der Schweißbacken 3 und Faltorgane 6 zur Verfügung gestellt, so daß die beiden Faltorgane 6 den Hüllstoff nach innen auf die Füllgutoberfläche falten können. Der rechte Teil der Figur 1 zeigt die entsprechende Endstellung der Faltorgane 6, in der der Hüllstoff glatt und straff an der Füllgutoberfläche anliegt und mit dem von der anderen Seite einwärts bewegten Hüllstoff zur Bildung einer Querschweißnaht verschweißt werden kann. Die Faltvorrichtung 14 führt dabei ausschließlich eine Horizontalbewegung durch. Eine Anpassung der Faltvorrichtung an mögliche Füllstandsschwankungen ist über eine manuelle Höhenverstellung möglich. In Verbindung mit der Einwärtsbewegung der Hauptfaltorgane bewegen sich auch die Seitenfalter 11 nach innen in die im unteren Teil der Figur 2 gezeigte Stellung, so daß danach die Querschweißnaht erzeugt werden kann.After filling the tubular bag 12 with filling material 8 (this state is also shown in the left part of FIG. 1) the lifting device 10 starts the lifting device 9 to lift. Move in conjunction with this stroke the two welding jaws 13 together with the two Folding organs 6 horizontally inwards, i.e. towards the bag axis. By lifting the filled tubular bag 12 will be additional coating material in the area of Welding jaws 3 and folding organs 6 provided, see above that the two folding organs 6 the envelope on the inside can fold the product surface. The right part of the Figure 1 shows the corresponding end position of the folding members 6, in which the wrapper is smooth and taut on the product surface is applied and with that from the other side inward moving material to form a cross weld can be welded. The folding device 14 leads doing only a horizontal movement. A Adaptation of the folding device to possible level fluctuations is possible via a manual height adjustment. In Move connection with the inward movement of the main folding organs the side moth 11 inward in the lower part of Figure 2 position, so that afterwards the cross weld can be created.
