Abstract

Gegenstand der Erfindung ist eine Fördereinrichtung mit Dosierpumpen (5) für die Entnahme von Materialien aus Behältern (1, 2), insbesondere für 2-Komponenten-Anlagen, welche von einem Luftmotor (24) antreibbar ist, mit einem in einem Pumpenzylinder (9) angeordneten und mittels einer Kolbenstange (12, 13) hin und her beweglichen Kolben (11) und mit dem Pumpenzylinder (9) verbundenen Ansaug- und Ausgangsleitungen (3, 4; 20, 21), wobei an jedem Pumpenzylinderende je eine Ansaug- und Ausgangsleitung (3, 4; 20, 21) angeschlossen ist, in jede Ansaug- und Ausgangsleitung (3, 4; 20,21) je ein in gleicher Strömungsrichtung wirkendes Rückschlagventil (15, 16; 17, 18) eingeschaltet ist, die Ansaugleitungen (3, 4) und Ausgangsleitungen (20, 21) jeweils in Strömungsrichtung vor bzw. nach den Rückschlagventilen (15, 16; 17, 18) miteinander verbunden sind und der Luftmotor (5) mit seinem Antriebskolben (29) in axialer Verlängerung der Kolbenstange (12, 13) der Dosierpumpe (5) angeordnet ist. Damit die Fördereinrichtung einfach im Aufbau und einfach zu montieren ist und nur einem geringen Verschleiß unterliegt, sind mehrere Dosierpumpen (5) in axialer Ausrichtung hintereinander angeordnet, wobei deren Kolbenstangen (12, 13) entweder mit der Kolbenstange (23) des Luftmotors (24) und/oder mit der Kolbenstange (12, 13) benachbarter Dosierpumpen (5) verbunden sind, daß jede Dosierpumpe (5) aus zwei miteinander verbundenen Platten (6, 7) besteht, zwischen denen der den Kolben (11) aufnehmende Pumpenzylinder (9) eingespannt ist und daß die Anschlußbohrungen (14) für die Ansaug- und Ausgangsleitungen (3, 4; 20, 21) in den Platten (6, 7) ausgebildet sind.

The invention relates to a conveyor device with metering pumps (5) for removing materials from containers (1, 2), in particular for 2-component systems, which can be driven by an air motor (24), with a pump cylinder (9). Arranged and by means of a piston rod (12, 13) reciprocating piston (11) and connected to the pump cylinder (9) suction and outlet lines (3, 4; 20, 21), with one suction and outlet line at each pump cylinder end (3, 4; 20, 21) is connected, a check valve (15, 16; 17, 18) acting in the same flow direction is switched on in each intake and outlet line (3, 4; 20,21), the intake lines (3 , 4) and output lines (20, 21) in the flow direction before or after the check valves (15, 16; 17, 18) are connected to each other and the air motor (5) with its drive piston (29) in axial extension of the piston rod (12 , 13) of the metering pump (5) is arranged . So that the conveyor is simple in construction and easy to assemble and is subject to little wear, a number of metering pumps (5) are arranged one behind the other in axial direction, their piston rods (12, 13) either with the piston rod (23) of the air motor (24) and / or with the piston rod (12, 13) of adjacent metering pumps (5) that each metering pump (5) consists of two interconnected plates (6, 7) between which the pump cylinder (9) receiving the piston (11) is clamped and that the connection bores (14) for the suction and outlet lines (3, 4; 20, 21) are formed in the plates (6, 7).
