Description

Die Erfindung betrifft eine Vorrichtung zum Stützen eines Kunststoffprofiles, insbesondere für ein Kunststoffrohr, in einer Kalibrier- und/oder Kühleinrichtung, die einen Stützbereich aufweist, in dem sie das Kunststoffprofil stützt.The Invention relates to a device for supporting a plastic profile, especially for one Plastic pipe, in a calibration and / or cooling device, which has a support area in which it supports the plastic profile.

Bei heute im Einsatz befindlichen Extrusionslinien werden beim Wechsel von einer Dimension auf die andere neben der Kalibriervorrichtung auch die im Vakuumtank beispielsweise befindlichen Stützscheiben ausgetauscht und durch Scheiben mit einem anderen Radius ersetzt. Dies bedeutet wiederum, dass für jedes zu produzierende Produkt entsprechend angepaßte Stützscheiben vorrätig sein müssen. Bei der Rohrextrusion werden somit Scheiben für unterschiedliche Rohrdurchmesser bereitgehalten. Dies erhöht den Lagerbedarf sowie die Rüstzeit, da wie oben beschrieben die Scheiben gewechselt werden.at The extrusion lines in use today are changing from one dimension to the other next to the calibration device also in the vacuum tank, for example, support disks replaced and replaced by discs with a different radius. This in turn means that for Each product to be produced correspondingly adapted support discs available have to be. In the tube extrusion thus slices for different pipe diameters kept ready. This increases the storage requirements and the set-up time, as described above, the discs are changed.

Aus der DE 202 07 037 U1 ist eine Kalibriervorrichtung bekannt, bei der ein elastisch verformbares Bauteil in seiner lichten Weite veränderbar ist. Das Bauteil umschließt das zu extrudierende Kunststoffprofil vollständig. Aus der DE 103 24 187 A1 ist eine Vorrichtung bekannt, mit der Rohre auf Rollen geführt werden und die vertikale Lage der Rollen in Abhängigkeit des Rohrdurchmessers über Mittel angepasst wird.From the DE 202 07 037 U1 a calibration device is known in which an elastically deformable component is variable in its clearance. The component completely surrounds the plastic profile to be extruded. From the DE 103 24 187 A1 a device is known, are guided with the pipes on rollers and the vertical position of the rollers is adjusted depending on the pipe diameter via means.

Aufgabe der Erfindung ist es, eine Stützvorrichtung anzubieten, die es ermöglicht, auf den aufwendigen Wechsel der Scheiben zu verzichten.task The invention is a support device offer that makes it possible to dispense with the complex change of the discs.

Die Lösung der Aufgabe ist in Verbindung mit dem Oberbegriff des Anspruches 1 oder 8 dadurch gekennzeichnet, dass einerseits der Stützbereich durch einen in seiner Geometrie veränderbaren flexiblen Körper, der das Profil im unteren Bereich stützt, aber nicht vollständig umschließt oder andererseits der Stützbereich durch eine Flüssigkeitssäule erzeugt und über einen regulierbaren Flüssigkeitsdruck ein Stützprofil abgebildet wird.The solution the object is in connection with the preamble of the claim 1 or 8, characterized in that on the one hand the support area by a variable geometry flexible body, which supports the profile in the lower area, but does not completely enclose or on the other hand, the support area generated by a liquid column and over an adjustable fluid pressure a support profile is shown.

Es werden also keine fixen Stützelemente eingesetzt, sondern ein in seiner Geometrie veränderbarer Körper eingesetzt, der sich an die Außenkontur des zu stützenden Profiles anlegt. Der flexible Körper ist somit an die Kontur des Kunststoffprofiles weitgehend anpassbar.It So no fixed support elements are used, but a body changeable in its geometry, which adapts itself the outer contour of the to be supported Profiles creates. The flexible body is thus largely adaptable to the contour of the plastic profile.

Weiterbildungsgemäß ist vorgesehen, dass der flexible Körper aufgeblasen wird, er kann aber auch mit einem flüssigen Medium befüllt werden, so dass die Kontur sich wie oben beschrieben an das Kunststoffprofil anlegt, um es zu stützen.Training is provided, that the flexible body is inflated, but it can also be filled with a liquid medium, so that the contour as described above to the plastic profile to support it.

Wird eine Unterstützung über einen längeren Bereich benötigt, können mehrere flexible Körper nacheinander angeordnet werden, die sich alle an das gleiche Profil und dessen Geometrie anpassen, wobei dies unabhängig voneinander geschehen kann.Becomes a support over one longer range needed can several flexible bodies in succession be arranged, all to the same profile and its Adjust geometry, which can be done independently.

Jeder der flexiblen Körper weist ein von außen zugängliches Ventil auf, um das Aufblasen oder Befüllen zu gewährleisten. Der flexible Körper wird somit durch Beaufschlagen mit Druck in oder außer Eingriff gebracht, liegt also einerseits am zu stützenden Profil an oder ist ausreichend vom Profil beabstandet, dass dieses ungehindert durch den Tank gezogen werden kann.Everyone the flexible body indicates from outside accessible Valve open to ensure inflation or filling. The flexible body is thus in or out of engagement with pressure So on the one hand to be supported Profile or is sufficiently spaced from the profile that this can be pulled through the tank unhindered.

Über geeignete Mittel, die beispielsweise den Druck feststellen, ist vorgesehen, dass außerhalb der Kalibrier- und/oder Kühleinrichtung die Größe des am flexiblen Körper eingestellten Stützradius erkennbar ist, wobei hier nicht zwingend ein Radius abgebildet sein muss.About suitable Means that detect, for example, the pressure is provided that outside the calibration and / or cooling device the size of the am flexible body set support radius recognizable is, where not necessarily a radius must be shown.

In einer weiteren Ausführung wird nicht das gesamte Becken geflutet, sondern nur ein Teilbereich oder mehrere Teilbereiche. Es wird hier daran gedacht, mittels zweier in der Kalibrier- und/oder Kühleinrichtung eingesetzter zueinander beabstandeter Wände einen Kanal zu bilden, in dem eine Flüssigkeitssäule erzeugt wird, auf der ähnlich eines Springbrunnens das Extrudat geführt wird. Über den regulierbaren Flüssigkeitsdruck, im Normalfall kommt hier Wasser zum Einsatz, werden unterschiedliche Stützbereiche abgebildet. Somit ist es möglich, auch auf Veränderungen im Durchmesser des zu extrudierenden Rohres zu reagieren.In another embodiment is not flooded the entire basin, but only a partial area or several subareas. It is thought of here, by means of two in the calibration and / or cooling device inserted spaced walls to form a channel, in which a liquid column is generated will, on the similar a fountain the extrudate is passed. About the adjustable fluid pressure, Normally, water is used here, will be different support areas displayed. Thus, it is possible also on changes to react in the diameter of the tube to be extruded.

In den Zeichnungen ist schematisch ein Ausführungsbeispiel dargestellt, es zeigt:In The drawings schematically illustrate an embodiment, it shows:

1 den Stützbereich für einen kleinen Rohrdurchmesser und 1 the support area for a small pipe diameter and

2 den Stützbereich für einen größeren Rohrdurchmesser. 2 the support area for a larger pipe diameter.

1 zeigt eine Kalibrier- und/oder Kühleinrichtung 1, ein dort durchlaufendes Kunststoffrohr 2 sowie drei darin angeordnete flexible Körper 3. Die flexiblen Körper 3 sind derart im Umfang verändert, dass sie das zu stützende Kunststoffrohr im unteren Bereich stützen. In der dargestellten Seitenansicht gemäß 1b wird deutlich, dass der flexible Körper sowohl den unteren Bereich des Profiles 2 als auch den seitlichen unteren Teil mit stützt. Dies wird beispielsweise durch die entsprechende Materialwahl des flexiblen Körpers ausgelegt, wobei hieran gedacht ist, dies durch unterschiedliche Wandstärken zu erreichen. Bereiche mit dünner Wandstärke dehnen sich stärker aus als Bereiche mit dickerer Wandstärke. Ein ähnlicher Effekt wird beispielsweise bei aufblasbaren Luftballons erreicht, die bestimmte Figuren wiedergeben. 1 shows a calibration and / or cooling device 1 , a plastic pipe running therethrough 2 and three flexible bodies arranged therein 3 , The flexible body 3 are so varied in scope that they support the plastic pipe to be supported in the lower area. In the illustrated side view according to 1b It becomes clear that the flexible body both the lower part of the profile 2 as well as the lateral lower part with supports. This is designed for example by the appropriate choice of material of the flexible body, which is thought to achieve this by different wall thicknesses. Areas with thin wall thickness expand more than areas with thicker wall thickness. A similar effect is for example in reached inflatable balloons that play certain characters.

2 zeigt die gleiche Vorrichtung wie in 1 beschrieben, jedoch wird hier durch die Kalibrier- und/oder Kühleinrichtung 1 ein Kunststoffrohr 2 mit einem größeren Durchmesser durchgeführt. Die flexiblen Körper 3 sind hier in ihrem Umfang weniger stark verändert worden, so dass auch dieses größere Rohr 2 nicht aus seinem Extrusionsmittelpunkt herausgedrückt wird. Die Schnittdarstellung gemäß 2b zeigt wieder, dass auch in diesem Fall der flexible Körper 3 das Rohr 2 weitgehendst zu einem Drittel des Umfanges stützt. 2 shows the same device as in 1 but described here by the calibration and / or cooling device 1 a plastic tube 2 performed with a larger diameter. The flexible body 3 have been changed less in scope here, so that even this larger pipe 2 is not pushed out of its extrusion center. The sectional view according to 2 B shows again that even in this case the flexible body 3 the pipe 2 largely based on one third of the circumference.

Mittels dieses flexiblen Körpers oder der Flüssigkeitssäule ist es somit möglich, unterschiedliche Rohrdurchmesser zu stützen und bei entsprechender Ausgestaltung auch für bestimmte Profile eingesetzt werden zu können, da, wie oben beschrieben, nicht nur Kreisquerschnitte abbildbar sind. Der Stützbereich bildet auch nicht einen zwingend geometrisch bestimmten Radius, sondern kann auch eine Kurve abbilden. Mittels der vorgeschlagenen Vorrichtung ist man in der Lage, eine Kalibrier- und/oder Kühleinrichtung für unterschiedliche Profilquerschnitte einzusetzen, ohne aufwendige Umrüstungen vorzunehmen.through this flexible body or the liquid column it is thus possible support different pipe diameters and with appropriate Design also for certain profiles can be used because, as described above, not only circular cross sections are mapped. The support area also does not form a necessarily geometrically determined radius, but can also map a curve. By means of the proposed device one is able, a calibration and / or cooling device for different Use profile cross sections, without complicated conversions make.
