Abstract

The system gives even delivery of two-ingredient adhesives and fusible adhesives by plunger pumps. The stroke of the driving cylinder is detected and evaluated, and a constant stroke speed is produced by means of an adjustable hydraulic valve. This speed can preselected as a desired value and set, for achievement by the valve. The design gives a steady discharge rate even under variable back-pressure through the medium handled.

Description

Beschreibung zur PatentanmeldungDescription of the patent application

Verfahren zum gleichmäßigen Ausstoß von Zveikomponentenklebern und Schmelzklebern mittels tolbenpumpen. Process for the even output of two-component adhesives and Hot melt adhesives by means of piston pumps.

Die Erfindung betrifft die Erzielung eines gleichmäßigen Förderstromes von Zweikomponentenklebern oder Schmelzklebern, zum Beispiel beim Randverkleben von Isolierglas.The invention relates to achieving a uniform flow rate of two-component adhesives or hot-melt adhesives, for example for edge bonding of insulating glass.

Bisher veränderte sich die Ausflußgeschwindigkeit des Fördermaterials bei Verwendung von pneumatisch- oder hydraulisch angetriebenen Kolbenpumpen je nach Materialviskosität, Temperaturunterschied, Leistungsquerschnitt etc.So far, the outflow speed of the conveyed material has changed when using pneumatically or hydraulically driven piston pumps depending on Material viscosity, temperature difference, power cross-section, etc.

Dies erforderte z.B. beim Versiegeln von Isolierglas eine Ziehgeschwindigkeitsanpassung der Spritzdüse an die unterschiedlichen Ausflußgeschwindigkeiten.This required an adjustment of the pulling speed when sealing insulating glass, for example the spray nozzle to the different outflow velocities.

Durch die Erfindung wird erreicht, daß eine einstellbare Ausflußgeschwindigkeit auch bei veränderten Gegendrücken durch das zu fördernde Medium beibehalten wird.The invention achieves that an adjustable outflow rate is maintained by the medium to be conveyed even with changed counter pressures.

Die Erfindung ist dadurch gekennzeichnett daß die Hubbewegung des Antriebzylinders und damit der Pumpe elektronisch erfaßt wird, elektronisch ausgewertet wird und silber ein Proportionalventil oder verstellbares Hydraulikventil die vorgewählt Hubgeschwindigkeit des Antriebzylinders durchgeführt wird.The invention is characterized in that the lifting movement of the Drive cylinder and thus the pump is detected electronically, evaluated electronically and silver a proportional valve or adjustable hydraulic valve is preselected Lifting speed of the drive cylinder is carried out.

Die Vorwahl der konstanten Hubgeschwindigkeit erfolgt als Sollwert über ein Potentiometer und wird über die elektronische Auswertung von dem verstellbaren Hydraulikventil nachvollzogen.The constant lifting speed is pre-selected as a setpoint via a potentiometer and is via the electronic evaluation of the adjustable Hydraulic valve reconstructed.
