Description

Vorrichtung zum Einfalten und Querverschließen eines Verpackungsschlauches Die Erfindung betrifft eine Vorrichtung zum Einfalten und Querverschließen eines aus faltbarem und schweißbarem Material bestehenden Verpackungsschlauches unter Bildung eines standfesten Packungsbodens, bestehend aus einander gegenüberliegenden und gegeneinander quer zum Schlauch bewegbaren, im Bereich ihres Vorderteils keilförmig gestalteten Faltwinkeln, welche beim Querverschließen eines Schlauchabschnitts senkrecht zur Bewegung der ihnen zugeordneten Schweißbacken unter Einfalten des Schlauches aufeinander zuführbar sowie zur Erzielung eines ebenen Beutelbodens um eine Achse quer zur Schlauchlängsachse in eine Ebene senkrecht zu letzterer schwenkbar sind.Device for folding in and transversely closing a packaging tube The invention relates to a device for folding in and cross-closing a made of foldable and weldable material under the existing packaging tube Formation of a stable packing base, consisting of mutually opposite and mutually movable transversely to the tube, wedge-shaped in the area of their front part designed folding angles, which are perpendicular when closing a tube section transversely for moving the welding jaws assigned to them while folding in the hose can be fed to one another and to achieve a flat bottom of the bag around an axis are pivotable transversely to the tube's longitudinal axis in a plane perpendicular to the latter.

Bei den bekannten Maschinen zum Herstellen von gefüllten Beuteln aus einem Verpackungsschlauch besitzen die fertigen Beutel, sofern das Ausgangsmaterial in Folienform verarbeitet wird, zwei Schweiß-oder Siegelnähte in Querrichtung und eine Naht in Längsrichtung. Die Quernähte werden dabei durch Schweiß- oder Siegelbacken in der Weise erzeugt, daß diese von beiden Seiten auf den Folienschlauch einwirken und unter Druck und Temperatur die beiden Folienhälften miteinander verbinden. So hergestellte Beutel besitzen den Nachteil, daß ihnen eine Standfläche fehlt, so daß sie einerseits mangelnde Stabilität besitzen und zum andern eine Stapelung in aufrechter Lage nicht zulassen. In the known machines for producing filled bags The finished bags have a packaging tube, provided they are the starting material is processed in film form, two welding or sealing seams in the transverse direction and one seam in the longitudinal direction. The transverse seams are made by welding or sealing jaws generated in such a way that these act on the film tube from both sides and connect the two halves of the film to one another under pressure and temperature. So Manufactured bags have the disadvantage that they lack a standing surface, so that on the one hand they have a lack of stability and on the other hand they are stacked in do not allow the upright position.

Bei einer bekannten Vorrichtung zur Herstellung von gefüllten Beuteln mit standfesten Beutelböden aus einem Seitenfaltenschlauch sind zur Formung der Beutelenden vier ebene Faltwinkel vorgesehen, die paarweise ober- und unterhalb von Querverschlußbacken angeordnet sind. Eine sichere und einwandfreie Bodenbildung ist durch diese Ausbildung der Faltwinkel nicht gewährleistet. In a known device for producing filled bags with stable bag bottoms made of a gusseted tube are used to shape the Bag ends are provided with four flat folding angles, in pairs above and below are arranged by cross-locking jaws. A safe and perfect soil formation the folding angle is not guaranteed by this design.

Der Erfindung liegt die Aufgabe zugrunde, die aus einem Schlauch geformten Beutel in vereinfachter Weise mit einem sauber eingefalteten Boden zu versehen, welcher die Standfähigkeit in jedem Fall gewährleistet. The invention is based on the object that consists of a hose shaped pouch in a simplified manner with a neatly folded bottom provided, which guarantees the stability in any case.

Ausgehend von einer Vorrichtung der eingangs genannten Art, wird zur Lösung dieser Aufgabe erfindungsgemäß eine Vorrichtung vorgeschlagen, bei der nur zwei Faltwinkel oberhalb von quer zur Faltwinkelschwenkachse gemeinsam verschiebbaren Querschweißbacken vorgesehen sind, wobei jeder Winkel aus zwei spiegelbildlich zueinander angeordneten Klappen besteht, die in ihrer Ausgangslage einen Winkel kleiner als 1800 einschließen und die nach dem Zusammenführen der Querschweißbacken um eine gemeinsame Achse in die Ebene senkrecht zur Schlauchachse unter Andrücken der gefalteten Schlauchwandteile an die Backen schwenkbar sind. Starting from a device of the type mentioned at the beginning to solve this problem proposed according to the invention a device in which only two folding angles above can be moved together transversely to the folding angle pivot axis Cross welding jaws are provided, each angle consisting of two mirror images of one another arranged flaps, which in their starting position an angle smaller than 1800 include and after the joining of the cross welding jaws by one common axis in the plane perpendicular to the tube axis while pressing the folded Hose wall parts are pivotable on the jaws.

Durch die Schwenkbarkeit der geteilten Faltklappen der Vorrichtung nach der Erfindung wird neben einer genauen Faltung des Schlauchs auch die Möglichkeit des Andrückens und Ansiegelns der eingefalteten Beutelwände und damit der Formung eines stabilen Standbodens geschaffen. Due to the pivotability of the divided folding flaps of the device According to the invention, in addition to a precise folding of the hose, there is also the possibility the pressing and sealing of the folded bag walls and thus the shaping created a stable base.

Bei der erfindungsgemäßen Vorrichtung ist die Anordnung weiterhin so getroffen, daß jede Klappe eines Faltwinkels an einem starren Halter befestigt ist, der in in einem Kurvenstück ausgesparten Bahnen geführt ist. Das Kurvenstück ist dabei zusammen mit den Faltwinkeln in Richtung senkrecht zu den Schmalseiten des Schlauchabschnittes verschiebbar. In the device according to the invention, the arrangement continues taken so that each flap of a folding bracket is attached to a rigid holder which is guided in paths recessed in a curved piece. The curve piece is together with the folding angles in the direction perpendicular to the narrow sides of the hose section displaceable.

Die Halter der Klappen der Faltwinkel sind über Lenker mit einem Betätigungswinkelhebel verbunden.The holders of the flaps of the folding angle are on handlebars with an operating angle lever tied together.

An Hand der Zeichnung wird eine beispielsweise Ausführung der Erfindung näher erläutert. Es zeigt Fig. 1 eine perspektivische Darstellung der am Folienschlauch angreifenden Faltwinkel und Querschweißbacken der Vorrichtung, Fig. 2 bis 4 dieselbe Vorrichtung wie F i g. 1, jedoch in einer anderen Phase des Bewegungsablaufs der Faltwerkzeuge, F i g. 5 die Vorderansicht eines Faltwinkels mit einer diesem zugeordneten Führungsbahn, Fig. 6 die Seitenansicht der Faltwinkel gemäß F i g. 5 teilweise geschnitten (Schnitt A-B), F i g. 7 die Draufsicht auf den Faltwinkel nach Fig. 6. An example embodiment of the invention is shown on the basis of the drawing explained in more detail. 1 shows a perspective illustration of the film tube attacking folding angle and cross welding jaws of the device, Fig. 2 to 4 the same Device as in FIG. 1, but in a different phase of the movement sequence of the Folding tools, FIG. 5 shows the front view of a folding bracket with an associated one Guide track, FIG. 6 shows the side view of the folding angle according to FIG. 5 partially cut (Section A-B), F i g. 7 the top view of the folding angle according to FIG. 6.

Wie den F i g. 1 bis 4 zu entnehmen ist, ist jeder Stirnseitel, 2 des Folienschlauchs 3 mit rechteckförmigen Querschnitt ein Faltwinkel 4, 5 zugeordnet, von denen jeder aus zwei um eine Achse 6 bzw. 7 in Pfeilrichtung gegeneinander verschwenkbaren Klappen 8, 9 besteht, die oberhalb von Querschweißbacken 18 angeordnet sind. Like the fig. 1 to 4 can be seen, each end face, 2 of the film tube 3 with a rectangular cross-section is assigned a folding angle 4, 5, each of which can be pivoted relative to one another about an axis 6 or 7 in the direction of the arrow Succeed 8, 9, which are arranged above transverse welding jaws 18 are.

Der Mechanismus zum Verschwenken der beiden Klappen umfaßt dabei im Prinzip eine Schubstange 10, die gelenkig an einem starren Winkelhebel 11 angreift, der mit einer drehbar gelagerten Achse 12 vereinigt ist. Am einen Ende des Winkels 11 sind gelenkig zwei Lenker 13 angebracht, die an den Klappen 8, 9 befestigt sind. Bewegt sich die Schubstange 10 in Pfeilrichtung, dann dreht sich die Achse 12 um ein dem Maß dieser Auslenkung entsprechenden Winkel. Damit öffnen oder schließen auch die Lenker 13 im Sinne einer entsprechenden Veränderung des eingeschlossenen Winkels ç von kleiner als 1800, durch den die Lage der Klappen 8, 9 bestimmt ist. Der besseren Übersicht halber ist der für beide Faltwinkel vorgesehene Schweriniechanismus nur in Verbindung mit-dem Faltwinkel 5 gezeichnet. The mechanism for pivoting the two flaps includes in principle a push rod 10, which engages in an articulated manner on a rigid angle lever 11, which is combined with a rotatably mounted shaft 12. At one end of the angle 11, two links 13 are articulated, which are attached to the flaps 8, 9. If the push rod 10 moves in the direction of the arrow, then the axis 12 rotates an angle corresponding to the extent of this deflection. Open or close with it also the handlebars 13 in the sense of a corresponding change in the included Angle ç of less than 1800, through which the position of the flaps 8, 9 is determined. For the sake of clarity, the heavy line canonism provided for both folding angles only drawn in connection with the folding angle 5.

Die Vorrichtung zum Vorschub der Faltwinkel in Richtung senkrecht zu den Stirnseiten 1, 2 des Folienschlauchs besteht grundsätzlich aus einer Schubstange 14, die auf einen starren, um eine vertikale Achse 15 drehbaren Winkelhebel 16 einwirkt, der über einen Lenker 17 mit der axial verschiebbaren Schubstange gekoppelt ist. Diese Vorrichtung ist auch nur einmal, und zwar in Verbindung mit dem Faltwinkel 4 angedeutet. The device for advancing the folding angle in the perpendicular direction to the end faces 1, 2 of the film tube basically consists of a push rod 14, which acts on a rigid angle lever 16 rotatable about a vertical axis 15, which is coupled to the axially displaceable push rod via a link 17. This device is also only once, namely in connection with the folding angle 4 indicated.

Der zeitliche Ablauf des Faltvorganges ist wie folgt: Nach dem Vorschub des Schlauchs 3 um das vorgesehene Maß beginnt jeder Faltwinkel 8, sich auf die ihm zugeordnete Stirnseite 1 des Folienschlauchs hin zu bewegen; d. h., die beiden Faltwinkel führen eine gegenläufige Bewegung aus. Das Ausmaß dieser Vorschubbewegung richtet sich dabei nach der erforderlichen Eindringtiefe der Faltwinkel in die betreffenden Seiten des Folienschlauchs. The timing of the folding process is as follows: After the feed of the tube 3 to the intended extent, each folding angle 8 begins to focus on the to move the end face 1 of the film tube assigned to it; d. i.e., the two Folding angles perform an opposite movement. The extent of this feed movement depends on the required depth of penetration of the folding angle into the relevant Sides of the film tube.

Während der Bewegung der Faltwinkel beginnen bereits auch die beiden Schweißbacken 18, sich aufeinander zu zu bewegen. Nach Beendigung der Vorschubbewegung der Faltwinkel werden die beiden Klappen 8 so weit gegeneinander verschwenkt, bis sie jeweils auf einen der in der Zwischenzeit in die Schließ- bzw.Schweißstellung gelangten Schweißbacken 18 zur Auflage kommen. During the movement of the folding angles, the two of them also begin Welding jaws 18 to move towards each other. After the end of the feed movement the folding angle, the two flaps 8 are pivoted against each other until they each to one of the meanwhile in the closed or welded position reached welding jaws 18 come to rest.

Mit dem Ausschwenken der beiden Klappen werden die beiden dreieckförmigen Bodenteile des Schlauchabschnittes ausgeprägt. Daraufhin folgen die Querschweißung bzw. die Siegelung und das Abtrennen der Beutel (Fig. 3). Damit keine senkrecht zur Bodenebene des Beutels verlaufende Naht entsteht, werden die beiden Schweißbacken gemeinsam ein Stück weiterbewegt, so daß der die Naht enthaltende Kamm 19 des Beutels umgedrückt wird (Fig. 4). Durch Aufbringen eines zusätzlichen Drucks entsprechender Größe auf die beiden Klappen der Faltwinkel, wobei einer der beiden Siegelbacken als Widerlager dient, läßt sich mit Hilfe der auch an ihrer Oberseite erwärmten Schweißbacke ein Anschweißen bzw. Ansiegeln des umgelegten Kamms an den Beutelboden erzielen. Insbesondere wird sich eine Siegel- bzw. Schweißnaht im Bereich der unmittelbar wirkenden Anpreßflächen ergeben. When the two flaps are swiveled out, the two become triangular Bottom parts of the hose section pronounced. This is followed by the cross welding or the sealing and separation of the bags (Fig. 3). So no vertical The seam running to the bottom level of the bag is created, the two welding jaws become moved a little further together, so that the comb 19 of the bag containing the seam is pressed (Fig. 4). Appropriate by applying additional pressure Size on the two flaps of the folding angle, with one of the two sealing jaws serves as an abutment, can be heated with the help of the top Welding jaw a welding or sealing of the folded comb to the bottom of the bag achieve. In particular, there will be a sealed or welded seam in the area of the immediately acting contact pressure result.

Nach der Herstellung des Beutelbodens einschließlich des Verschließens auf die vorbeschriebene Art wird der Füllvorgang eingeleitet. After the bottom of the bag has been manufactured, including closing the filling process is initiated in the manner described above.

Eine konstruktive Ausführung der Faltwinkel mit einer vorteilhaften Führung zeigen die F i g. 5 bis 7. A constructive implementation of the folding angle with an advantageous Leadership show the F i g. 5 to 7.

Hier sind die beiden Klappen 8, 9 des Faltwinkels jeweils mit einem Halter 20 vereinigt, der Bolzen 21, 22 aufweist, auf die Kugellager 23, 24 aufgesetzt sind. Here are the two flaps 8, 9 of the folding angle each with one Combined holder 20, which has bolts 21, 22, placed on ball bearings 23, 24 are.

Diese Lagerrollen laufen in Führungsbahnen 25, 26, die in einem Kurvenstück 27 ausgespart sind.These bearing rollers run in guideways 25, 26 in a curved piece 27 are recessed.

Die Klappen der Faltwinkel können dabei auch unter der Wirkung einer Rückstellkraft in Form einer Feder od. dgl. stehen, die vor dem Ausschwenken erst zu überwinden ist. Zu diesem Zweck können besondere Betätigungsglieder, wie Schwenkhebel od. dgl., vorgesehen sein, die beispielsweise abhängig von der Lage der Schweißbacken gesteuert sind. The flaps of the folding angle can also under the effect of a Restoring force in the form of a spring or the like is to be overcome. For this purpose, special actuators, such as pivot levers Od. The like. Be provided, which, for example, depends on the position of the welding jaws are controlled.
