Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Es zeigen Fig.1 eine Vorrichtung zum Herstellen, Füllen und Verschließen von Beuteln vereinfacht in Vorderansicht und die Fig.2 bis Fig.6 die Vorrichtung nach Fig.1 während verschiedener Phasen der Beutelherstellung vereinfacht in Vorderansichten.An embodiment of the invention is shown in the drawing and is explained in more detail in the following description. 1 shows a device for producing, filling and closing of bags simplified in front view and the Fig.2 to Figure 6 shows the device of Figure 1 during various phases of Bag production simplified in front views.
Die Vorrichtung (Fig.1) hat eine Schlauchformeinrichtung 10, bestehend
aus einer Formschulter 11 und einem Formrohr 12, sowie eine
Längsnahtsiegeleinrichtung 13, mit denen in bekannter Weise eine
Kunststoff-Folienbahn 14 zu einem Schlauch 16 geformt wird. Beiderseits
des Formrohrs 12 ist in Höhe der Längsnahtsiegeleinrichtung 13
je eine Abzugseinrichtung in Form eines vakuumunterstützten Förderbandes
18 für den Schlauch 16 angeordnet. In dem Formrohr 12 ist ein
innerhalb eines bestimmten Bereichs, beispielsweise 20 mm, aufund
abbewegbares Innenrohr 19 mit einem damit verbundenen Mundstück 20
angeordnet. Die Länge des Innenrohrs 19 mit dem Mundstück 20 ist dabei
größer als die Länge des Formrohrs 12. Die eine Seite des Mundstücks
20 ist am Austritt 17 am unteren Ende des Formrohrs 12 der
Form des Formrohrs 12 angepasst, hat also beispielsweise eine runde
Form, und wird von diesem nahezu formschlüssig umschlossen. Somit
ergeben sich insbesondere keine den Schlauch 16 möglicherweise beschädigenden
Kanten beim Übergang vom Formrohr 12 auf das Mundstück
20. Die dem Innenrohr 19 gegenüberliegende Seite des Mundstücks 20
hat einen
Boden 21, dessen Form einem zu faltenden Blockboden angepasst ist,
also insbesondere eine rechteckige Form hat. Weiterhin ist im Boden
21 eine Öffnung 22 für das Füllgut vorhanden. Der Bereich zwischen
den beiden Seiten des Mundstücks 20 ist derart ausgebildet, daß ein
kontinuierlicher Übergang zwischen den beiden runden bzw. rechteckigen
Seiten geschaffen wird.
Das Innenrohr 19 bzw. das Mundstück 20 ist über ein Gestänge 23 mit
einem beispielsweise pneumatisch betriebenen und fest mit der Vorrichtung
verbundenem Stellzylinder 25 gekoppelt.
Unterhalb des Mundstücks 20 ist ein in Förderrichtung des Schlauches
16 auf- und abbewegbares Quernahtbackengehäuse 27 angeordnet. Auf
diesem ist eine Packstoffaltvorrichtung 30 mit Seitenfaltlöffeln 31
befestigt. Die Packstoffaltvorrichtung 30 ist quer zur Förderrichtung
des Schlauches 16 auf dem Quernahtbackengehause 27 bewegbar.
Weiterhin ist auf dem Quernahtbackengehäuse 27 eine Quernahtsiegeleinrichtung
32 mit Quernahtbacken 33 angeordnet, deren Schließbewegung
mit der Bewegung der Seitenfaltlöffel 31 über ein Kurvengetriebe
synchronisiert ist. Der Quernahtsiegeleinrichtung 32 ist eine
nicht dargestellte Schneideinrichtung zum Abtrennen von Beuteln 35
von dem Schlauch 16 zugeordnet.
Oberhalb der Packstoffaltvorrichtung 30 befindet sich beiderseits
des Mundstücks 20 je eine Klemmeinrichtung 36, die ebenfalls fest
mit dem Quernahtbackengehäuse 27 verbunden sind. Die Klemmeinrichtungen
36 haben beispielsweise pneumatisch betriebene Haltebacken
37, deren dem Mundstück 20 zugewandten Stirnflächen 38 dem Mundstück
20 formschlüssig angepasst sind.The device (FIG. 1) has a

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist in den
Fig.2 bis Fig.6 vereinfacht dargestellt, wobei der Einfachheit halber
insbesondere auf eine Darstellung des Schlauches 16 und der Beutel
35 verzichtet wurde. The operation of the device according to the invention is in the
Fig. 2 to Fig. 6 are shown in simplified form, for the sake of simplicity
in particular, a representation of the hose 16 and the
In einer Anfangsposition der Vorrichtung (Fig.2) befindet sich das
das Innenrohr 19 mit dem Mundstück 20 in einer angehobenen Position,
so daß lediglich das Mundstück 20 aus dem Formrohr 12 austritt. Dies
wird durch Beaufschlagung des Stellzylinders 25 mit einem entsprechenden
Unterdruck erzielt. Die Förderbänder 18 fördern den Schlauch
16, der durch die Längsnahtsiegeleinrichtung 13 aus der Kunststoff-Folienbahn
14 gebildet wurde, kontinuierlich über das Formrohr 12
und das Mundstück 20. Gleichzeitig bewegt sich das Quernahtbackengehäuse
27 entgegen der Förderrichtung des Schlauches 16 aus einer abgesenkten
Position nach oben, wobei sich die zuvor in einer weit geöffneten
Position befindlichen Quernahtbacken 33 und die mit ihnen
gekoppelte Packstoffaltvorrichtung 30 kurz vor Erreichen des oberen
Totpunkts der Bewegungsbahn des Quernahtbackengehäuses 27 zu schließen
beginnen. Bei der sich nach Erreichen des oberen Umkehrpunkts
anschließenden, abwärts gerichteten Beschleunigungsphase des Quernahtbackengehäuses
27 wird die Fördergeschwindigkeit des Schlauches
16 mittels der Förderbänder 18 der Geschwindigkeit des Quernahtbackengehäuses
27 angepasst. Wenn die Geschwindigkeit des Quernahtbackengehäuses
27 und die des Schlauches 16 gleich sind, befindet sich
der zur Bildung des Blockbodens nötige Überstand des Schlauches 16
unterhalb des Bodens 21 des Mundstücks 20. Gleichzeitig werden die
zuvor in einer zurückgefahrenen Position befindlichen Haltebacken 37
der Klemmeinrichtungen 36 angesteuert und gelangen unter Zwischenlage
des Schlauches 16 in formschlüssigem Kontakt mit dem Mundstück
(Fig.3).
Daraufhin wird der Stellzylinder 25 belüftet, und das Mundstück 20
wird von dem Quernahtbackengehäuse 27 zusammen mit diesem mit einer
der Fördergeschwindigkeit des Schlauches 16 entsprechenden Geschwindigkeit
mit diesem parallel bewegt (Fig.4). Somit ergibt sich während
der Abwärtsbewegung des Mundstücks 20 und des
Quernahtbackengehäuses 27 ein konstanter Überhang des Schlauches 16
in Bezug auf den Boden 21. In dieser Phase wird von der Packstoffaltvorrichtung
30 mit dem Überhang des Schlauches 16 und mit Hilfe
des Bodens 21 ein Blockboden gefaltet, sowie anschließend von den
Quernahtbacken 33 eine Quernaht gebildet. Mit der Bildung der Quernaht
geht gleichzeitig die Bildung einer Kopfquernaht an dem zuvor
hergestellten Beutel 35 und dessen Abtrennung vom Schlauch 16 durch
die Schneideinrichtung einher. Weiterhin wird, sobald die Quernahtbacken
33 geschlossen sind, durch das Innenrohr 19 ein Füllgut in
den Schlauch 16 eingebracht. Anschließend werden die Haltebacken 37
wieder in ihre ursprüngliche Position zurückgefahren, und durch einen
entsprechenden Unterdruck an dem Stellzylinder 25 beginnt sich
das Mundstück 20 anzuheben, bis es wieder seine ursprüngliche, angehobene
Position im Formrohr 12 erreicht hat (Fig.5). Das Quernahtbackengehäuse
27 befindet sich nun kurz vor seinem unteren Umkehrpunkt,
währenddessen die Seitenfaltlöffel 31 der Packstoffaltvorrichtung
30 zurückgeschwenkt werden (Fig.6), und die Quernahtbacken
33 sich zu öffnen beginnen. Im unteren Umkehrpunkt des Quernahtbackengehäuses
27 sind die Quernahtbacken 33 vollständig geöffnet. Nun
beginnt das Quernahtbackengehäuse 27 wieder mit seiner Aufwärtsbewegung,
wobei sich der weitere Verlauf wie oben beschrieben wiederholt.In an initial position of the device (FIG. 2), the
