- FIG. 1 3 to 3 schematically show the conventional manufacture of such Sealed bags or sachets 1. From a supply roll 2 peeled a packaging film 3, separated in the middle and the two webs 4 formed thereby over deflecting rods and deflecting rollers merged. In a first station with rotating Sealing rolls longitudinal seal seams 5 formed between which the products are filled in 6 portions before a final transverse sealing seam 7 is formed.
- the sachets 1 are by longitudinal cuts 8 in the middle through the Longitudinal sealing seams 5 and 9 cross cuts through the middle Cross seal seams 7 separated into individual sachets 1 ( Figure 1).
- perforations instead of cross cuts 10 form so that strips of through the perforations 10 connected sachets 1 arise ( Figure 2).
- Figure 3 Another known variant ( Figure 3) is the formation of double sachets 1 by using two longitudinal sealing seams 5 instead of a separating cut 8 a perforation 11 is cut.
- the present invention has for its object the manufacture to simplify such sealed edge bag and a device to create that is flexible in application. This The problem is solved by the combination of features of the claims.

Abstract
Description
Pulverförmige oder schüttfähige Produkte in kleinen Dosierungen
oder auch Einzelprodukte wie Bonbons oder Dragées werden meist
in sogenannte Sachets, d.h. in rechteckige Siegelrandbeutel verpackt,
bei denen alle vier Kanten Siegelnähte haben. Figuren 1
bis 3 zeigen schematisch die herkömmliche Herstellung solcher
Siegelrandbeutel oder Sachets 1. Von einer Vorratsrolle 2 wird
eine Verpackungsfolie 3 abgezogen, in der Mitte getrennt und die
beiden dadurch gebildeten Bahnen 4 über Umlenkstäbe und Umlenkwalzen
zusammengeführt. In einer ersten Station werden mit umlaufenden
Siegelrollen Längssiegelnähte 5 gebildet, zwischen
welche die Produkte 6 portionenweise eingefüllt werden, bevor
eine abschliessende Quersiegelnaht 7 gebildet wird. Die Sachets
1 werden durch Längstrennschnitte 8 mittig durch die
Längssiegelnähte 5 und Quertrennschnitte 9 mittig durch die
Quersiegelnähte 7 in einzelne Sachets 1 getrennt (Figur 1). Alternativ
ist es auch möglich, statt der Quertrennschnitte Perforationen
10 zu bilden, so dass Streifen von durch die Perforationen
10 verbundenen Sachets 1 entstehen (Figur 2). Eine weitere
bekannte Variante (Figur 3) ist die Bildung von Doppel-Sachets
1, indem bei zwei Längssiegelnähten 5 statt eines Trennschnittes
8 eine Perforation 11 geschnitten wird. Powdery or pourable products in small doses
or even individual products such as candies or dragées are usually
in so-called sachets, i.e. packed in rectangular sealed bags,
where all four edges have sealed seams. Figures 1
3 to 3 schematically show the conventional manufacture of such
Sealed bags or sachets 1. From a

Diese Aufgabe wird durch die Merkmalskombination der Ansprüche gelöst.The present invention has for its object the manufacture to simplify such sealed edge bag and a device to create that is flexible in application. This The problem is solved by the combination of features of the claims.

Figuren 5 und 6 zeigen einen Querschnitt durch ein Quertrennmesser
20 und einen Gegenhalter 21. Zwei Wellen 22, 23 sind um parallele
Achsen 24, 25 gegenläufig drehbar durch separate Servomotoren
26, 27 (Figur 8) angetrieben. Die Wellen 22, 23 sind
über den grössten Teil ihrer Länge prismatisch. Sie haben je
zwei diametral gegenüberliegende Auflageflächen 28, 29, auf denen
zwei Messer 30 bzw. zwei Gegenhalter 31 mittels Leisten 32
und Schrauben 33 aufgespannt sind. Die Messer 30 sind mit ihrer
der Achse 24 zugewandten Stirnseite an Exzenterstiften 38 angeschlagen,
die an Schrauben 39 ausgebildet sind. Die Schrauben 39
sind in quer zu den Auflageflächen 28 verlaufende Gewindebohrungen
40 eingeschraubt. Durch diese Ausbildung kann der Umlaufradius
der Schnittkante 41 des Messers 30 eingestellt werden und
es wird verhindert, dass die Exzenterstifte 38 herausfallen können.Figures 5 and 6 show a cross section through a
Der Gegenhalter 31 hat eine zylindrische Aussenfläche 45. In einem
ersten Winkelsegment 46 ist die Fläche 45 in Achsrichtung
durchgehend. In einem zweiten Winkelsegment 47 sind in der Fläche
45 im Abstand voneinander Ausnehmungen 48 ausgefräst.The
Der Servomotor 26 der Welle 24 ist synchron mit dem Vorschub der
Verpackungsfolie 3 durch eine Steuereinrichtung 49 und einen
Regler 50 derart gesteuert, dass die Schnittkante 41 jeweils in
der Mitte einer Quersiegelnaht 7 auf die Folienbahnen 4 auftrifft.
Der Drehwinkel der Welle 23 ist in Abhängigkeit zum
Drehwinkel der Welle 22 durch die Steuereinrichtung 49 über einen
Regler 51 gesteuert. In der programmierbaren Steuereinrichtung
49 kann der Drehwinkel der Welle 23 gegenüber einer Mittelstellung
so verstellt werden, dass die Welle 23 entweder um den
halben Winkel der Winkelsegmente 46, 47 vorläuft oder nachläuft.
Wenn er vorläuft, wird wegen der Ausnehmungen 48 eine Perforation
10 geschnitten. Wenn er nachläuft, wird ein durchgehender
Trennschnitt 9 gebildet. Dadurch werden Streifen 12 einer programmierbaren
Anzahl zusammenhängender Sachets 1 gebildet, welche
durch Perforationen 10 voneinander getrennt sind (Figur 4).The
Auf die Wellen 22, 23 können auf der gegenüberliegenden Seite
der Leisten 58, 59 mit den Auflageflächen 28, 29 zusätzlich weitere
Messer 60 und Gegenhalter 61 montiert werden. Die Schnittkanten
62 der Messer 60 sind nur sehr kurz und im Abstand der
Längssiegelnähte 5 voneinander angeordnet oder im Doppelten dieses
Abstandes. Die Länge der einzelnen Schnittkanten 62 des Messers
60 ist geringer als die Breite der Längssiegelnähte 5 und
ihre Mitte fluchtet mit der Mitte dieser Siegelnähte 5. Dadurch
werden kurze Querschnitte 63 in die Längssiegelnähte 5 der Sachets
1 gebildet (Figur 9), die als Aufreisshilfe dienen. Die
Messer 60 sind ebenfalls mit Schrauben 39 mit Exzenterstiften 38
einstellbar.On the
Die beschriebene Vorrichtung ist sehr flexibel. Mit ihr können
Einzelsachets 1 oder Streifen 12 einer wählbaren Anzahl zusammenhängender
Sachets 1 gebildet werden. Das Einschneiden der
Aufreisshilfe 63 erfolgt in einem Arbeitsgang auf derselben Vorrichtung
wie die Bildung der Quertrennschnitte 9 bzw. Perforationen
10. Die Vorrichtung ist modulartig aufgebaut. Gleiche
Bauteile sind für verschiedene Funktionen eingesetzt. Dadurch
wird die Herstellung vereinfacht.The device described is very flexible. With her can
Individual sachets 1 or
Der relative Drehwinkel der Welle 23 gegenüber der Welle 22 kann
auch in drei diskrete Stellungen verstellbar sein, wobei in einer
dieser Stellungen die Schnittkante 41 die Fläche 45 des Gegenhalters
31 nicht berührt. Bei dieser Einstellung würden die
Streifen 12 ohne die Perforationen 10 gebildet.The relative angle of rotation of the
Alternativ zur dargestellten Ausführungsform können die beiden
Wellen 22, 23 durch einen gemeinsamen Motor über ein Differenzialgetriebe
angetrieben werden, wobei ein zusätzlicher Eingang
zum Differenzialgetriebe die Schaltfunktion zwischen den zwei
wählbaren Winkelsegmenten 46, 47 übernimmt.As an alternative to the embodiment shown, the two
Shafts 22, 23 by a common motor via a differential gear
be driven, with an additional input
to the differential gear the switching function between the two
