Description
Beim Durchgang eines jeden Materialpfropfens 9 durch die Förderleitung 1 wird jeweils kurz vor dem Erreichen der nächsten Druckluft-Einmündungsstelle die jeweilige Lichtschranke 6,7 durchfahren. Dadurch wird ein Impuls ausgelöst, der, durch den Verstärker 8 verstärkt, das zugehörige Magnetventil 4 öffnet und sofort wieder schließt. Der eindringende Druckluftstoß genügt, um die Länge des Materialpfropfens 9 zu begrenzen und ein Aufschieben desselben auf den vorangehenden Pfropfen 9 zu verhindern. When each material plug 9 passes through the delivery line 1, it is just before the When you reach the next compressed air junction, drive through the respective light barrier 6,7. Through this a pulse is triggered which, amplified by the amplifier 8, the associated solenoid valve 4 opens and closes again immediately. The penetrating blast of compressed air is sufficient to cover the length of the material plug 9 and to prevent it from being pushed onto the preceding plug 9.
Auf diese Weise wird jeder einzelne Materialpfropfen 9 bei seinem Lauf durch die Förderleitung verfolgt und auf richtiger Länge gehalten, ohne daß hierzu dauernd eine unkontrollierbare Zusatzluftmenge einströmen müßte. Auch kann die Länge der Pfropfen 9 durch Abschalten mehrerer nebenein-In this way, each individual plug of material 9 as it runs through the conveying line tracked and kept at the correct length without the constant need for an uncontrollable amount of additional air should flow in. The length of the plug 9 can also be adjusted by switching off several adjacent

Auch nachstehende Möglichkeit der Ermittlung des Durchgangs der Pfropfen ist denkbar: Es könnenThe following possibility of determining the passage of the plug is also conceivable: It can

It should be above the one in the delivery line. According to one alternative, the additional compressed air line 2, which is independent of the valves, is connected by branch pipes 3, depending on the requirements, at the points in question at certain intervals to the delivery line 1 and the air supply to the delivery line. In the branch pipes 3, solenoid valves 4 are increased, decreased or switched off. Turned on after the other.
