Description
Die Erfindung betrifft ein Verfahren zum Abdichten des Einzugsbereiches eines Vakuum- und Kalibriertankes in einer Extrusionslinie, wobei ein Schmelzeschlauch mittels eines Extruders in Verbindung mit einem Werkzeug erzeugt und der Vakuum- und Kalibriertank mit darin angeordneter Kalibrierhülse mit Vakuum beaufschlagt wird, wobei der Schmelzeschlauch nach Verlassen des Werkzeuges im Vakuum- und Kalibriertank derart mit Vakuum beaufschlagt wird, dass dieser an der Innenwandung der Kalibrierhülse und mindestens an der Innenkontur einer Ringöffnung in der Stirnwand des Vakuum- und Kalibriertankes anliegt, sowie einen Vakuum- und Kalibriertank.The The invention relates to a method for sealing the catchment area a vacuum and calibration tank in an extrusion line, wherein a melt tube by means of an extruder in conjunction with a Tool created and the vacuum and calibration tank with arranged therein Calibrating is applied with vacuum, wherein the Melting hose after leaving the mold in the vacuum and calibration tank is subjected to such a vacuum that this on the inner wall the calibration sleeve and at least on the inner contour of a Ring opening in the front wall of the vacuum and calibration tank and a vacuum and calibration tank.

Vakuum- und Kalibriertanks hinreichend bekannt. So beschreibt beispielsweise die
All
diese Vorrichtungen haben gemein, dass der Schmelzeschlauch nach
dem Verlassen des Werkzeuges von einem größeren
Durchmesser auf einen kleineren Durchmesser in die Kalibrierung
gezogen wird und der maximal herzustellende Durchmesser nur unwesentlich
den Durchmesser des Schmelzeschlauches nach dem Verlassen des Werkzeuges überschreiten
kann. Eine Abdichtung des Vakuumtankes muss mit geeigneten Mitteln
gesondert bewerkstelligt werden, auch hierfür werden im
Stand der Technik Möglichkeiten angeboten, wie dies zum Beispiel
die
Aufgabe der Erfindung ist es daher, ein Verfahren und eine Vorrichtung anzubieten, das/die einerseits bei unterschiedlichen Durchmessern bei der Rohrextrusion einsetzbar ist und eine einfache Abdichtung des Vakuums im Tank zur Umgebung realisiert.task It is therefore an object of the invention to provide a method and a device the one hand at different diameters in the pipe extrusion can be used and a simple sealing of the vacuum in the tank realized to the environment.
Die Lösung der Aufgaben ist in den Ansprüchen wiedergegeben.The Solution of the problems is given in the claims.
Es wird für das Verfahren in Verbindung mit dem Oberbegriff des Anspruches 1 vorgeschlagen, dass beim Verändern des Durchmessers der Kalibrierhülse bedingt durch das Vakuum im Vakuum- und Kalibriertank der Kontakt des Schmelzeschlauches zur Innenwandung der Kalibrierhülse erhalten bleibt, wobei beim Vergrößern oder Verkleinern des Durchmessers der Kalibrierhülse die Anlage des Schmelzeschlauches an der Innenkontur der Ringöffnung erhalten bleibt und somit eine Abdichtung der Umgebungsluft zum Inneren des Vakuum- und Kalibriertankes gewährleistet ist. Durch dieses Verfahren wird sichergestellt, dass keine Fehlluft gezogen wird und somit das Anlegen des Schmelzeschlauches an die Kalibrierhülse erschwert wird. Die Kalibrierhülse selbst kann zusätzlich noch Durchbrüche in Form von Schlitzen, Lochungen etc. aufweisen, durch die das Vakuum auf den Schmelzestrang wirken kann.It is used for the procedure in conjunction with the preamble of claim 1, that when changing the Diameter of the calibration due to the vacuum in the vacuum and calibration tank the contact of the melt tube remains to the inner wall of the calibration, wherein when enlarging or reducing the diameter the calibration sleeve the system of the melt tube the inner contour of the ring opening is maintained and thus a sealing of the ambient air to the interior of the vacuum and calibration tank is guaranteed. This procedure ensures that that no false air is drawn and thus the application of the melt tube is made difficult to the calibration. The calibration sleeve itself can additionally breakthroughs in the form of slots, Have holes etc., through which the vacuum on the melt strand can work.
Weiterbildungsgemäß ist vorgesehen, dass im Abstand zur Stirnwand des Vakuum- und Kalibriertankes angeordnete Stützelemente den Schmelzeschlauch beim Verändern des Durchmessers der Kalibrierhülse stützen und/oder führen. Der Schmelzeschlauch soll im Verlauf der Kalibrierhülse weitgehend tangential an die Innenwandung der Kalibrierhülse herangeführt werden, die Stützelemente sorgen dafür, dass dies vereinfacht möglich ist.Training is according to provided that at a distance to the end wall of the vacuum and calibration tank arranged support elements the molten tube when changing support the diameter of the calibration sleeve and / or to lead. The melt tube should be in the course of the calibration largely tangential to the inner wall of the calibration be introduced, provide the support elements that this is possible in a simplified way.
In einer weiteren Fortbildung ist vorgesehen, dass innerhalb des Vakuum- und Kalibriertankes angeordnete Sprühdüsen so gesteuert und/oder geregelt werden, dass ein Besprühen des Schmelzeschlauches mit einem Kühlmedium erst an einer Position innerhalb des Vakuum- und Kalibriertankes erfolgt, wo der Schmelzeschlauch an der Innenwandung der Kalibrierhülse anliegt. Der Schmelzeschlauch muss im vorderen Bereich der Kalibrierhülse noch gut verformbar sein, deshalb wird sichergestellt, dass in diesem Bereich keine Kühlung des Schmelzeschlauches erfolgt. Im Gegenteil, im Bedarfsfall kann der Schmelzeschlauch zusätzlich erwärmt werden. Dies kann über die Steuerung der Anlage umgesetzt werden, in dem die im Tank angebrachten Sprühdüsen individuell angesteuert werden, oder rein mechanisch, in dem im vorderen Bereich keine Düsen vorhanden sind. Ein Erwärmen des Bereiches kann erreicht werden, in dem beispielsweise die Stützelemente selbst mit einer Temperierung (Heizdraht auf der Stirnseite zum Schmelzeschlauch) versehen werden oder Heißluft zwischen die Stützelemente geblasen wird.In Further training is planned to be carried out within the vacuum and calibration tank arranged spray nozzles so controlled and / or regulated that a spraying the melt tube with a cooling medium only at one Position within the vacuum and calibration tank takes place where the Melting hose on the inner wall of the calibration sleeve is applied. The melt tube must be in the front area of the calibration sleeve still be well deformable, so be sure that in this Area no cooling of the molten tube takes place. in the Conversely, if necessary, the molten tube can additionally to be heated. This can be done by controlling the Implemented in the tank, the spray nozzles mounted in the tank be controlled individually, or purely mechanically, in the im front area no nozzles are present. A heating of the Range can be achieved, in which, for example, the support elements even with a temperature control (heating wire on the front side to the Melt tube) or hot air between the support elements is blown.
Die Lösung bezüglich der Vorrichtung ist in Verbindung mit dem Oberbegriff des Anspruches 4 dadurch gekennzeichnet, dass der Einzugsbereich eine Stirnwand des Vakuum- und Kalibriertankes mit einer Ringöffnung umfasst, wobei die Innenkontur der Ringöffnung eine Kontaktfläche aufweist, die ein Abdichten des mit Vakuum beaufschlagten Vakuum- und Kalibriertankes mittels eines Schmelzeschlauches ermöglicht. Wie schon beim Verfahren beschrieben, soll sichergestellt werden, dass eine Abdichtung des Vakuums zur Umgebung erreicht wird. Dafür ist die Innenkontur der Ringöffnung entsprechend vorbereitet. Sie hat eine ausreichende Breite, damit diese Abdichtung sichergestellt werden kann.The Solution regarding the device is in communication with the preamble of claim 4, characterized in that the catchment area is an end wall of the vacuum and calibration tank comprising an annular opening, wherein the inner contour of the Ring opening has a contact surface, which is a sealing the applied vacuum vacuum and calibration tank by means of a melt tube allows. As with the procedure described, it should be ensured that a seal of the Vacuum to the environment is achieved. This is the inner contour the ring opening prepared accordingly. she has a sufficient width to ensure this seal can.
Damit beim Verändern des Querschnittes der Kalibrierhülse der Schmelzeschlauch nicht unkontrolliert verläuft, sind fortbildungsgemäß mehrere Stützelemente zueinander beabstandet und senkrecht zur Extrusionsachse nebeneinander und im Inneren des Vakuum- und Kalibriertankes zur Stirnwand des Vakuum- und Kalibriertankes parallel angeordnet. Die im Inneren des Vakuum- und Kalibriertankes angeordnete Kalibrierhülse ist selbstverständlich verstellbar.Thus, when changing the cross section of the Kalibrierhülse the melt tube not un runs controlled, a plurality of support elements according to the education are spaced apart and arranged parallel to each other perpendicular to the extrusion axis and in the interior of the vacuum and calibration tank to the end wall of the vacuum and calibration tank. The arranged inside the vacuum and calibration tank calibration sleeve is of course adjustable.
Damit die Stützelemente weitgehend der Kontur des Schmelzeschlauches entsprechen ist weiterbildungsgemäß vorgesehen, dass sie einen zur Extrusionsachse bezogenen Radius aufweisen, wobei dieser Radius zum Radius benachbarter Stützelemente unterschiedlich ist. Dies ist erforderlich, da ja, wie oben beschrieben, der Schmelzeschlauch an die Wandung der Kalibrierhülse herangeführt wird, folglich verändert sich auch die Außenkontur des Schmelzeschlauches und damit das Erfordernis, dass entsprechende Stützelemente daran angepasst sind.In order to the support elements largely the contour of the melt tube corresponds to further education is provided that they have a radius related to the extrusion axis, wherein this radius is different from the radius of adjacent support elements is. This is necessary because, as described above, the molten tube brought to the wall of the calibration As a result, the outer contour also changes the melt tube and thus the requirement that appropriate Support elements are adapted thereto.
Da vorgesehen ist, den Schmelzeschlauch von einem kleinen zu einem großen Durchmesser aufzuweiten, ist in einer weiteren Fortbildung vorgesehen, dass der Radius der Stützelemente benachbarter Stützelemente in Extrusionsrichtung größer wird. Im Bedarfsfall können die Seite: 4 Stirnwand und die Stützelemente beheizt und an den Gleitflächen beschichtet ausgeführt werden. Des Weiteren kann ggf. das Vakuum im Bereich der Stirnwand und Stützelemente auch differieren gegenüber dem Vakuum im restlichen Tank.There is provided, the molten tube from a small to a widening large diameter is in another training provided that the radius of the support elements adjacent Supporting elements in the extrusion direction becomes larger. If necessary, the side: 4 end wall and the support elements heated and coated on the sliding surfaces executed become. Furthermore, if necessary, the vacuum in the region of the end wall and support elements also differ from that Vacuum in the rest of the tank.
In den Zeichnungen ist schematisch ein Ausführungsbeispiel der Erfindung wiedergegeben.In The drawings schematically show an embodiment reproduced the invention.
