Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum gleichzeitigen Trennen und Schweißen von Folien oder Folienschläuchen, welche zumindest einen Schweißbalken und einen Gegenbalken aufweist.The invention relates to a device for simultaneous cutting and welding of foils or foil tubes, which at least one sweat bar and has a counter bar.
Solche Vorrichtungen werden in der
Regel eingesetzt, um aus Folienschläuchen Beutel herzustellen.
Beim Schweißvorgang
werden der Schweißbalken
und der Gegenbalken zusammengepresst. Hierbei entsteht wie erwähnt sowohl
ein Trennschnitt als auch eine Schweißnaht, was den Produktionsvorgang
beschleunigt. Unter anderem die
In der Regel ist der Gegenbalken von dem zu verschweißenden Material durch ein Teflonglasgewebe geschützt. Dieses Gewebe verhindert das Anhaften der Folien am Gegenbalken. In der Regel wird das Teflonglasgewebe an dem Gegenbalken vorbeibewegt. Hierbei erfolgt die Bewegung intermittierend, da das Teflonglasgewebe während des Schweißprozesses nicht bewegt werden kann.Usually the counterbar of the one to be welded Material protected by a Teflon glass fabric. This tissue prevents the foils stick to the counter beam. Usually the Teflon glass fabric moved past the counter beam. Here the movement is intermittent, because the Teflon glass fabric during of the welding process cannot be moved.
Die Kräfte sowie die Temperaturen, denen Schweiß- und Gegenbalken ausgesetzt sind, verursachen Verschleiß. Daher werden diese Elemente oft mit Federelementen versehen, welche mit den Balken und ihren Aufhängungen verbunden sind.The forces and the temperatures, whom sweat and exposed to counterbeams cause wear. Therefore these elements are often provided with spring elements, which with the beam and its suspensions are connected.
Eine weitere Methode, den Verschleiß zu beschränken, besteht in der Verwendung eines drehbaren Gegenbalkens Diese drehbaren Gegenbalken sind in der Regel als Walze ausgeformt. Zwischen zwei Trennschweißprozessen wird die Walze gedreht, so dass ein anderer Teil der Walzenoberfläche der Schweißtemperatur und dem Druck des Trennschweißprozesses ausgesetzt wird. Oft werden auch diese drehbaren Gegenbalken von einem Teflonglasgewebe gegen ein Anhaften der verschweißten Folie geschützt. Aufgrund der Drehung des beschriebenen Gegenbalkens reich es oft aus, den Gegenbalken mit dem Teflonglasgewebe zu beschichten.Another method is to limit wear in the use of a rotatable counter beam These are rotatable counter beams usually shaped as a roller. Between two separation welding processes the roller is rotated so that another part of the roller surface of the welding temperature and the pressure of the separation welding process is exposed. Often these rotatable counterbeams are made by a Teflon glass fabric to protect the welded film from sticking. by virtue of the rotation of the counter beam described is often sufficient for the Coating the counter beam with the Teflon glass fabric.
In den letzten Jahren sind alle bereits erwähnten Ausführungsformen von Gegenbalken in dem beschriebenen Anwendungsbereich mit flexiblen Dämpfungskörpern ausgestattet worden, die zumindest einen Teil der dem Schweißbalken zugewandten Oberfläche des Gegenbalkens abdecken.In the past few years everyone has been mentioned embodiments of counter beams in the application area described with flexible Damping bodies equipped that have at least a part of the surface of the welding bar facing the Cover the counter bar.
Hierbei bestehen diese Dämpfungskörper in der Regel aus Silikon, Viton oder einem anderen flexiblen und temperaturbeständigen Material. Diese Materialien verringern zwar den Verschleiß der Balken, verschleißen aber selbst sehr schnell. Durch die Auswechslung dieser Dämpfungskörper oder gar des ganzen Schweißbalkens ergeben sich jedoch unerwünschte Standzeiten der Maschine.Here, these damping body in the Usually made of silicone, Viton or another flexible and temperature-resistant material. These materials reduce the wear of the beams, but they wear out even very quickly. By replacing this damping body or even the whole sweat bar however, undesirable results Machine downtimes.
Es ist Aufgabe der vorliegenden Erfindung, diese Standzeiten zu verringern. Diese Aufgabe wird dadurch gelöst, dass die dem Schweißbalken zugewandte Oberfläche des Dämpfungskörpers aus Metall besteht.It is an object of the present invention Reduce downtimes. This task is solved in that the sweat bar facing surface of the damping body Metal.
Metalle besitzen in der Regel eine höhere Abriebfestigkeit und Temperaturleitfähigkeit als die bisher in den flexiblen Dämpfungskörpern verwendeten Materialien.Metals usually have one higher abrasion resistance and thermal conductivity than the materials previously used in the flexible damping bodies.
Wenn das verwendete Metall biegsam ist, kann zumindest ein Teil der von dem Dämpfungskörper aufzubringenden Rückstellkraft direkt von dem Metall aufgebracht werden. Vorgespannte Federbleche eignen sich in diesem Zusammenhang besonderst gut. Auf der dem Schweißbalken beim Schweißprozess abgewandten Seite können Federelemente angebracht werden. Diese können alleine oder beispielsweise gemeinsam mit einem Federblech die dämpfende Wirkung und die Rückstellkraft aufbringen.If the metal used is pliable is, at least part of the restoring force to be applied by the damping body can be applied directly from the metal. Prestressed spring plates are particularly suitable in this context. On the sweat bar during the welding process opposite side can Spring elements are attached. These can be used alone or for example Apply the damping effect and the restoring force together with a spring plate.
Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor.Further embodiments of the invention go from the representational Description and claims out.
Die einzelnen Figuren zeigen:The individual figures show:
In der Regel verfügt einer oder gar beide Balken
In der Regel ist lediglich der Schweißbalken entlang der durch den Pfeil A skizzierten Richtung beweglich. Es ist jedoch ebenso gut möglich, beide Balken oder nur den Gegenbalken beweglich zu gestalten. Wichtig für die Funktion der Maschine ist lediglich, dass die beiden Balken in der Höhe der Schweiß- Trennstelle eine Relativbewegung beziehungsweise Beschleunigung ausführen, welche die zum Schweißen und Trennen der Folie notwendige Kraft bereitstellt.As a rule, only the welding bar can be moved along the direction outlined by arrow A. However, it is equally possible to make both beams or only the counter beam movable. It is only important for the function of the machine that the two bars execute a relative movement or acceleration at the height of the welding separation point, which is necessary for welding and cutting the film Provides strength.
