Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruches 1.
Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung nach dem Hauptpatent so auszugestalten, daß der Schweißbereich in seiner Länge variiert und der Banddimension und der zu erzeugenden Reibungswärme angepaßt werden kann, die für verschiedene Bandmaterialien unterschiedlich ist
Diese Aufgabe wird gemäß der Erfindung durch die Merkmale im Kennzeichen des Patentanspruches 1 gelöst
Diese Ausgestaltung hat den Vorteil, daß das obere, bewegte Bandende beim Hin- und Herschwingen der beweglichen Reibbacke nicht so hoch beansprucht wird wie von zwei beweglichen Backenteilen, die mit ihren einander zugekehrten Enden gleichgerichtete Schwenkbewegungen ausführen. Da bei dem hin- und herschwingenden Backenteil die Bewegung zur Schwenkachse hin immer kleiner wird und bis auf Null abnimmt, ist die Reibungswärme auch bei nur einer schwenkenden Reibbacke über die Länge des Schweißbereiches ungleich verteilt, so daß eine Schwächung des Bandes am Ende der Schweißzone nicht eintritt Da nur eine Reibbacke vorhanden ist, kann das obere Bandende mehr oder weniger weit unter die bewegliche Reibbacke geschoben werden. Hierdurch ist es möglich, die Länge des Schweißbereiches den Abmessungen und den Materialeigenschaften des jeweils zu verarbeitenden Bandes und der zu fibertragenden Zugkraft anzupassen. Zu diesem Zwecke können die Reibbacken an ihren einander zugekehrten Flächen auch in ihrer Breite verstellbare Nuten haben. Die Breite der Nuten in den Reibbacken kann durch Keilleisten verstellbar sein, welche einen Seitenrand der jeweiligen Nute bilden und in verschiedenen Stellungen arretierbar sind. Zu diesem Zweck können Verzahnungen an den Seitenwänden der Nute öder Stifte im Nutgrund angeordnet sein.
ίο Die Erfindung wird an einem Ausführungsbeispiel näher erläutert Es zeigt
F i g. 1 eine Reibungsschweißvorrichtung in einer schematischen, perspektivischen Darstellung,
Fig.2 den Gegenstand der Fig. 1 in einer Stirnansieht und teilweise im Schnitt nach Linie H-II der F i g. 1, Fig.3 den Gegenstand der Fig. 1 in einem senkrechten Teilquerschnitt nach Linie IH-III und
F i g. 4 den Gegenstand der F i g. 1 in einer Ansicht in Richtung des Pfeiles IV gesehen.
Die in ihrer Gesamtheit mit 10 bezeichnete Vorrichtung zum Verschweißen von Kunststoffbändern besteht aus einem hier nur in strichpunktierten Linien angedeuteten Gehäuse 50, das an seinem vorderen Rand eine feststehende Reibbacke 15 trägt Oberhalb dieser feststehenden Reibbacke 15 befindet sich die bewegliche Reibbacke 16, die mit einem Wellenzapfen 25 im Gehäuse um eine senkrechte Achse schwenkbar gelagert ist Die feststehende Reibbacke 15 und die bewegliche Reibbacke 16 erstrecken sich in Längsrichtung der miteinander zu verbindenden Kunststoffbänder 17 und 18 (Fig.2 bis 4). Das untere Band 18 liegt hierbei in einer Nute 19 der feststehenden Reibbacke 15, deren Breite B veränderbar ist und der Breite des Umreifungsbandes angepaßt werden kann. In analoger Weise befindet sich auf der Unterseite der beweglichen Reibbacke 16 eine Nute 22, in der das obere Bandende 17 liegt Auch diese Nute 22 ist in ihrer Breite veränderbar. Anstelle von Nuten können die Reibbakken auch mit einer Aufrauhung, insbesondere einer Verzahnung, versehen sein, die sich in die Bandoberfläche eindrückt so daß das obere Bandende bei der Schwenkbewegung der beweglichen Reibbacke mitgenommen wird.
Zum Einstellen der Breite B der Nuten 19 und 22 sind Keilleisten 51 und 52 vorgesehen, die an einer konischen Seitenfläche 53 bzw. 54 der Nute 19 bzw. 22 anliegen und die an ihren Keilflächen eine Verzahnung 55 aufweisen, mit der sie in eine entsprechende Verzahnung an der keilförmigen Seitenfläche 53 bzw. 54 der
so Nuten 19 bzw. 22 eingreifen. Damit die Keilleisten 51 und 52 nicht herausfallen, können sie durch hier nicht näher dargestellte Stifte oder Schrauben im Nutgrund befestigt sein.
Wie insbesondere aus den Fig. 1 und 3 hervorgeht, hat die bewegliche Reibbacke 16 einen Horizontalschlitz 30, in den eine Pleuelstange 36 eingreift die in der beweglichen Reibbacke 16 mit einem Zapfen 56 gelagert ist und an ihrem anderen Ende 57 von einem Exzenter 37 angetrieben wird, der mit einer Antriebsachse 38 in hier nicht näher dargestellter Weise im Gehäuse 50 gelagert ist Mit einer hier nicht näher dargestellten Druckvorrichtung 40 kann auf die bewegliche Reibbacke 16 ein Druck in Richtung des Pfeiles Pausgeübt werden.
Die Wirkungsweise der Vorrichtung ist folgende:
Zunächst wird durch Längsverschieben der Keilleisten 51 und 52 die Breite der Nuten 19 und 22 auf die Breite der miteinander zu verbindenden Kunststoff-
ORIGINAL INSPECTED
bandenden 17 und 18 eingestellt Danach werden die Bänder 17 und 18 übereinanderliegend in die Vorrichtung 10 eingelegt und gespannt Hierbei kann das obere Bandende 17 über die Vorderkante der beweglichen Reibbacke 16 hinausstehen, sie kann aber auch je nach der gewünschten Länge des Schweißbereiches an einer weiter zurückliegenden Stelle enden. Hierbei liegt die bewegliche Reibbacke 16 mit ihrer ganzen Fläche auf dem oberen Bandende auf, so daß ihre Auflagefläche auf dem Bandende 17 größer ist als der Schweißbereich, in welchem die Bandenden an ihren aufeinanderliegenden Flächen erweicht werden und eine Materialverschmelzung eintritt
Nach dem Einschalten des Antriebes wird die Antriebsachse 38 gedreht und der Exzenter 37 erteilt der Pleuelstange 36 eine hin- und hergehende Bewegung. Hierdurch wird die bewegliche Reibbacke 16 um ihren Wellenzapfen 25 hin- und hergeschwenkt wobei gleichzeitig auf die Reibbacke 16 mit der Druckvorrichtung 40 ein Druck P ausgeübt wird. Bei der hin- und hergehenden Schwenkbewegung der beweglichen Reibbacke 16 wird das in der Nute 22 liegende obere Band 17 mitgenommen und gegenüber dem darunterliegenden Band 18 unter Druck hin- und herbewegt. Hierdurch wird eine über die Länge des oberen Bandendes zum Wellenzapfen 25 hin abnehmende Reibungswärme erzeugt die die einander zugewandten Flächen der Bandenden aufschmilzt und miteinander verschweißt
In diesem Zusammenhang ist darauf hinzuweisen, daß die Tiefe t der Nuten 19 und 22 etwas kleiner ist als die Dicke der Bandenden 17 und 18, so daß bei der hin- und hergehenden Bewegung nur die Bandenden, nicht aber die Reibbacken aufeinanderliegen.
Da die Auslenkung am vorderen Rand 59 der beweglichen Reibbacke 16 wesentlich größer ist als am hinteren Rand in der Nähe des Wellenzapfens 25, ist auch die Erwärmung der aufeinanderreibenden Kunststoffbänder 17 und 18 in der Nähe des freien Endes 59 der beweglichen Reibbacke größer als in der Nähe des Wellenzapfens 25. Hierdurch geht die Zone inniger Verschmelzung beider Bandenden allmählich in jene Zone über, wo die Bänder ohne Verschweißung aufeinanderliegen.
Die Reibbacken können auch eine etwas andere Form haben und die bewegliche Reibbacke kann auf andere Weise schwenkend angetrieben sein. Es ist auch möglich, die Breite der Nuten fur die zu verbindenden Bänder mit anderen Mitteln zu verändern.
