Description
Vorrichtung zum Zusammenschweissen von heissiegelfähigen Faltlappen Die Erfindung betrifft eine Vorrichtung zum Zusammenschweissen von heissiegelfähigen Faltlappen auf mindestens einer Fläche von Packungen mittels eines erwärmten Schweissgliedes. Es ist allgemein bekannt, bei der Herstellung von Packungen, die an die Flächen eines Gegenstandes angelegten Faltlappen von Packungen mittels Schweissbacken oder-stempeln zusammen zu schweissen. Diese Schweissglieder werden meist durch elektrische Stromstösse erwärmt und müssen so lange auf die Schweissstelle aufgepresst bleiben, bis sie unter die Fliesstemperatur des zu verschweissenden Materials abgekühlt sind, damit eine einwandfreie Schweissung erzielt werden kann. Dies bedingt, dass der Schweissvorgang eine gewisse Zeit beansprucht, während welcher die zu verschliessende Packung unter dem Schweissglied angehalten werden muss. Die Förderung der Packungen kann deshalb nur schrittweise erfolgen. Um eine höhere Produktion zu erreichen, hat man bereits vorgeschlagen, die Schweissbacken mit den Pakkungen über eine gewisse Strecke mitzubewegen und sie dann wieder in ihre Ausgangslage zurückzubewegen. Der Schweissvorgang kann dann während der Förderbewegung der Packungen vollzogen werden. Dies bedingt aber einen grossen konstruktiven Aufwand. Oft ist auch bei Verpackungsmaschinen der für solche eine und herlaufende Schweissbacken erforderliche Raum nicht vorhanden. Die Erfindung bezweckt eine Vorrichtung zu schaffen, welche die erwähnten Nachteile nicht aufweist. Erfindungsgemäss ist das Schweissglied ein endloses, über Umlenkrollen geführtes umlaufendes Metallband, das durch beheizte Umlenkrollen und/oder durch Heissgasdüsen beheizt ist. Vorzugsweise sind zwei endlose Metallbänder vorgesehen, die über einen Teil ihrer Länge parallel verlaufen und eine Förderstrecke für die Packungen bilden, wobei sie die Packungen auf ihren Stirnseiten festklemmen. In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. Es zeigen: Fig. 1 eine erste Ausführungsform einer Vorrichtung zum Befestigen von heissiegelfähigen Faltlappen in schematischer Darstellung; Fig. 2 eine Variante der Vorrichtung nach Fig. 1; Fig. 3 eine Ansicht eines endlosen Metallbandes mit zusätzlichen Anpressrollen und Fig. 4 eine Draufsicht auf Fig. 3. Die Vorrichtung g nach Fig. 1 weist zwei endlose Metallbänder 2 auf, die um Umlenkrollen 3, 4 umlaufen. Die beiden Metallbänder bilden ein Fördermittel für die Packungen 1, die in einer Führung 5 von einer Faltvor richtsur4g zugeführ, werden. Die Packungen 1, aus heiss- siegelfähigem Einschlagmaterial sind bereits fertiggestellt, doch müssen an ihren Stirnseiten die eingefalteten Lappen noch zusammengeschweisst werden. Die Umlenkrollen 3 sind zu diesem Zweck mittels elektrischen Widerstandselementen 6 beheizt. Sie übertragen ihre Wärme auf die Metallbänder 3, die somit als Schweissglieder wirken und während ihres Umlaufes die Faltlappen festschweissen. Um die Temperatur der Metallbänder 2 unter die Fliesstemperatur des Ein schlagmaterials zu senken, bevor die Packungen 1 freigegeben werden, sind vor den Umlenkrollen 4 eine Anzahl Kaltluftdüsen 7 angeordnet. Es hat sich gezeigt, dass als Bandmaterial für die Bänder 2 am zweckmässigsten ein Metallgeflecht verwendet wird. Gute Resultate wurden mit einem Tressengewebe erzielt, dessen Schussdrähte 0,34 und dessen Kettendrähte 0,28 mm Durchmesser aufweisen. In Fig. 2 ist eine andere Ausführungsform der Vor richtun, g dargestellt. Die Metall band er 2 und die Umlenk- rollen 3,4 sind grlualdsätich gleich wie in Fig. 1 ansge- bildet. Die-Beheizung der Bänder 2 und der Umlenkrollen 3 erfolgt dagegen durch eine grössere Zahl von Heissluft- oder Heissgasdüsen 8, die schraffiert dargestellt sind, während die Kühlluftdüsen 7 der Ausführungsform nach Fig. 1 entsprechen. Nötigenfalls können, wie dargestellt, die Umlenkrollen 4 ebenfalls durch Kühlluftdüsen 7 gekühlt werden. Um eine bessere Anpressung der Metallbänder an die Stirnseiten der Packungen 1 zu erzielen, können gegen das auf die Stirnseiten der Packung gerichtete Trum der Metallbänder 2 Anpressrollen wirken, die über Blattfedern 10 oder ähnliche Federmittel auf einem Träger 11 befestigt sind, der seinerseits zur Veränderung der Anpresskraft der Rollen 9 verstellbar ist. Die Verteilung der Rollen 9 über die Breite und Länge des Metallbandes 2 ist aus Fig. 4 ersichtlich. Zwischen den einzelnen Rollenreihen können Heissgasdüsen und nötigenfalls auch Kühlluftdüsen gemäss der Ausführungsform nach Fig. 2 vorgesehen sein.
