Abstract

The temperature and/or pressure of melt in the extruder is measured at the running rings where similar connections(22,23) are used for both temperature and/or pressure measurement.

Description

Die Erfindung betrifft einen Planetwalzenextruder. Planetwalzenextruder sind spezielle Extruder. Extruder dienen vorzugsweise der Verarbeitung von Kunststoff Dabei wird Kunststoff zumeist in Granulatform zusammen mit Zuschlägen in den Extruder eingesetzt. Die Einsatzmischung wird plastifiziert, homogenisiert, anschließend auf Extrusionstemperatur abgekühlt und im schmelzflüssigen Zustand wieder ausgetragen. Die Austragdüse wird als Extruderwerkzeug bezeichnet.The invention relates to a planetary roller extruder. Planetary roller extruders are special extruders. Extruders are preferably used the processing of plastic Here plastic is mostly in Granulate form together with supplements used in the extruder. The insert mixture is plasticized, homogenized, then cooled to extrusion temperature and in the molten Condition carried out again. The discharge nozzle is used as an extruder tool designated.

Der Planetwalzenextruder hat gegenüber anderen Extruderformen beim Plastifizieren, Homogenisieren und Abkühlen erhebliche Vorteile.The planetary roller extruder has compared to others Extruder molding in plasticizing, homogenizing and cooling considerable Benefits.

Deshalb gewinnt der Planetwalzenextruder zunehmende Bedeutung.That is why the planetary roller extruder is becoming increasingly popular Importance.

Seine besondere Wirkungsweise gewinnt der Planetwalzenextruder durch seinen Aufbau und die Wirkungsweise seiner Einzelteile. Kern des Planetwalzenxtruders ist eine Zentralspindel, die mit einer Vielzahl von Planetenspindeln(Planetwalzenspindeln) kämmt. Zumeist handelt es sich um 6 bis 12 Planetenspindeln. Die Zahl der Planetenspindeln steht in der Regel im Zusammenhang mit dem Extruderdurchmesser.The wins its special mode of action Planetary roller extruder due to its structure and mode of operation Individual parts. The core of the planetary roller extruder is a central spindle, with a variety of planetary spindles (planetary roller spindles) combs. Mostly there are 6 to 12 planetary spindles. The number of Planetary spindles are usually related to the extruder diameter.

Die Planetspindeln kämmen zugleich mit der Innenverzahnung einer umgebenden Gehäusebuchse oder der Innenverzahnung des Gehäuses. Während der Drehung der Zentralspindel laufen die Planetenspindeln um die Zentralspindel um.The planetary spindles mesh at the same time with the internal teeth of a surrounding housing bush or the internal teeth of the housing. While the rotation of the central spindle, the planetary spindles run around the Central spindle around.

Die Einsatzmischung wird zwischen der Zentralspindel, den Planetenspindeln und der Buchse in extremer Weise bearbeitet. Die Bearbeitung ist intensiv und besonders schonend, weil die Molekühlketten nicht oder nur minimal geschert werden.The insert mix is between the central spindle, the planetary spindles and the bush in extreme Edited way. The processing is intensive and particularly gentle, because the molecular chains are not or only minimal shear.

Die Zentralspindel wird in axialer Richtung durch Lager gehalten, welche die Axialkräfte aufnehmen. Die Planetenspindeln laufen gegen einen in Strömungsrichtung der Schmelze am Ende der Planetenspindeln angeordneten Anlaufring. Sie gleiten mit Ihren Stirnflächen entlang der Stirnfläche des Anlaufringes.The central spindle becomes axial Direction held by bearings that absorb the axial forces. The planetary spindles run against you in the flow direction of the melt thrust ring arranged at the end of the planetary spindles. They slide with you Your end faces along the face of the thrust ring.

An jedem Extruder ist es wichtig zu wissen, wie hoch die Schmelzetemperatur und wie hoch der Schmelzedruck ist. Deshalb ist es üblich, die Extruder mit Temperaturfühlern und Druckfühlern auszurüsten. Die Fühler werden üblicherweise so angebracht, daß die Druckspitzen und Temperaturspitzen gemessen werden.It is important on every extruder knowing how high the melt temperature and how high the melt pressure is. That's why it's common the extruders with temperature sensors and pressure sensors equip. The feelers are common so attached that the Pressure peaks and temperature peaks are measured.

Die Planetwalzenextruder sind aufwendiger als andere Extruder wie z.B. Einschneckenextruder und Doppelschneckenextruder. Deshalb liegt der Erfindung die Aufgabe zugrunde, zu einer Reduzierung des wirtschaftlichen Aufwandes beizutragen.The planetary roller extruders are more complex than other extruders such as Single screw extruder and twin screw extruder. Therefore, the invention has for its object to reduce the to contribute economic expense.

Dabei geht die Erfindung von der Überlegung aus, eine Vereinfachung bei der Anordnung der Fühler zu erreichen. Die Erfindung setzt sich dabei über das Prinzip der Spitzenmessung hinweg und ordnet die Fühler in den Anlaufringen an. Dabei hat die Erfindung erkannt, daß die dort ermittelten Werte ebenso wie die Spitzenwerte zur Regelung des Extruders geeignet sind, weil der Temperaturverlauf und Druckverlauf im Extruder durch die Messung an anderer Stelle nicht verändert wird bzw. für einen bestimmten Temperaturverlauf und Druckverlauf auch an anderen Stellen als den Spitzenstellen gemessen werden kann.The invention is based on the consideration to achieve a simplification in the arrangement of the sensors. The invention sits over that Principle of peak measurement and arranges the sensors in the thrust rings. The invention has recognized that there determined values as well as the peak values are suitable for controlling the extruder are because of the temperature curve and pressure curve in the extruder the measurement is not changed elsewhere or for one certain temperature profile and pressure profile also in other places than the top spots can be measured.

Besonders günstige Verhältnisse ergeben sich, wenn ein Planetwalzenextruder aus mehreren Planetwalzenmoduln zusammengesetzt ist. Alle Moduln sind dann mit einer gemeinsamen Zentralspindel versehen, jedoch besitzt jeder Modul eigene bzw. separate Planetwalzenspindeln, denen ein besonderer Anlaufring zugeordnet ist. Im Falle der Modulbauweise ist nach der Erfindung an jedem Modul eine Temperaturmessung und/oder Druckmessung an den Anlaufringen möglich.Particularly favorable conditions arise when a planetary roller extruder composed of several planetary roller modules is. All modules are then with a common central spindle provided, but each module has its own or separate planetary roller spindles, which is assigned a special thrust ring. In the case of modular construction is a temperature measurement and / or according to the invention on each module Pressure measurement on the thrust rings possible.

Vorzugsweise sind alle Bohrungen für die Temperaturmessung und Druckmessung gleich ausgelegt, so daß sie wechselweise für die eine oder die andere Messung benutzt werden können. Daneben ist noch eine Nutzung zum Eintragen von Treibmitteln oder zum Eintragen anderer Zumischungen an den Anlaufringen vorgesehenen. Die nicht genutzten Bohrungen können mit Blindstopfen geschlossen werden. Vor diesem Hintergrund kann es zweckmäßig sein die Anschlüsse in Überzahl vorzusehen und die überzähligen Anschlüsse zu verschließen. Das ist unabhängig von der Anordnung der Anschlüsse an den Anlaufringen von Vorteil. Die Überzahl kann dadurch entstehen, daß an einer Vielzahl üblicherweise unterschiedlicher für die Temperatur und Druckmessung genutzten Stellen Anschlüsse vorbereitet sind.All holes are preferred for temperature measurement and pressure measurement designed the same, so that they alternately for one or the other measurement can be used. Next to it is another Use to enter propellants or to enter others Additions provided on the thrust rings. The unused holes can be with Blind plugs are closed. With this in mind, it can be appropriate the connections in excess to be provided and the surplus connections to be closed. The is independent on the arrangement of the connections on the thrust rings is an advantage. The majority can result from that at a variety of usually different for the Places used for temperature and pressure measurement Connections prepared are.

Sofern die Druck- und Temperturmessungen und/oder Injektoren unterschiedliche Anschlüsse besitzen, kann dem mit Adaptoren abgeholfen werden.If the pressure and temperature measurements and / or The injectors have different connections Adapters are remedied.
