Abstract

Method of measuring out liquid plastic material using piston operated pumps, using drive cylinders hydraulically coupled to each other in order to ensure that a synchronised and equalised stroke is obtained. Different measuring out proportions maybe obtained by a variation of the dia. of the drive cylinders and of the piston rod. A further variation of the measuring out ratio can be obtained by the use of superimposed by-pass cylinders of corresponding volume which have also got a hydraulic connection to the drive cylinder.

Description

Beschreibung zur Patentanmeldung Description of the patent application

Verfahren zum Dosieren von Flüssigkunststoffen mittels Kolbenpumpen durch hydraulische Verkoppelung von Hub zylindern.Method for dosing liquid plastics using piston pumps through hydraulic coupling of lifting cylinders.

Die Erfindung betrifft die Verriegelung znTreier oder mehrerer Kolbenpumpen zum Dosieren von Flüssigkunststoffen.The invention relates to the locking of three or more piston pumps for dosing liquid plastics.

Man bezweckt damit die Erzielung verhältnisgleicher Förderströme bzw. Mengen beim Pumpen von Flüssigkeiten z. B. beim Verarbeiten von Zweikomponenten-Kunststoffen.The purpose of this is to achieve proportionate flow rates or Quantities when pumping liquids e.g. B. when processing two-component plastics.

Bisher wurden Kolbenpumpen dazu mechanisch über Hebelbalken (Fig. 1 ) oder direkt (Fig. 2 ) miteinander verbunden, so daß eine synchrone oder verhäl tnisgleiche Hubbewegung durchgeführt wurde.So far, piston pumps have been used mechanically via lever bars (Fig. 1) or directly (Fig. 2) connected to each other, so that a synchronous or proportional the same lifting movement has been carried out.

Das bedingte eine räumliche und mechanische Abhängigkeit der Pumpen und erforderte z. T. separate Zusatzpumpen als Zuführeinheiten zu den Dosierpumpen.This caused the pumps to be spatially and mechanically dependent and required z. T. separate additional pumps as feed units for the metering pumps.

Mit der Erfindung wird erreicht, daß die dosierenden Kolbenpumpen aller Komponenten ohne mechanische Verbindunngen synchrone bzw. verhältnisgleiche Hubbewegungen ausführen und direkt in das Material gebinde getaucht werden können.With the invention it is achieved that the metering piston pumps all components are synchronous or have the same ratio without mechanical connections Carry out lifting movements and can be dipped directly into the material container.

Die Erfindung ist dadurch gekennzeichnet, das die Antriebshubzylindder der Kolbenpumpen hydra isch derart miteinander verbunden sind, daß das Aböl des druckbeaufschlagten Zylinders in den Druckraum des zweiten Zylinders geleitet wird und diesen synchron, je nach Durchmesser, verhältnisgleich mitbewegt.The invention is characterized in that the drive lift cylinders the piston pumps are hydra isch interconnected in such a way that the oil of the pressurized cylinder is passed into the pressure chamber of the second cylinder and this synchronously, depending on the diameter, moved proportionally.

Durch die Wahl unterschiedlicher Zylinder- und tolbenstangendurchmesser werden andere Hubhöhen erreicht und damit andere Dosierverhältnisse, Durch Druckbeaufschlagung der anderen Seite des zweiten Zylinders wird die Bewegungsrichtung in gleicher Weise umgekehrt ( Fig. 3 ).By choosing different cylinder and piston rod diameters other lift heights are achieved and thus different dosing ratios, by applying pressure the other side of the second cylinder will move the direction in the same way vice versa (Fig. 3).

Weiterhin ist es möglich die Hub- und damit de Dosierverhältnisse durch Aufsetzen eines Bypass-Zylinders mit entsprechenden Durchmesser zu variieren, indem dieser Zylinder mechanisch mit einem Dosierzylinder verbunden ist und hydraulisch gekoppelt wird.It is also possible to adjust the stroke and thus the dosing ratios to vary by adding a bypass cylinder with the appropriate diameter, by connecting this cylinder mechanically to a dosing cylinder and hydraulically is coupled.
