Description

B e s chreibunK In Aufbereitungs-und Förderanlagen, vor allem bei Formsandaufbereitungsanlagen in Gießereien werden Vorailos durch ein Förderband (1) oder dergl. beschickt. Dabei wird das Füllgut durch mechanische Abstreifer (3) vom Förderband in den jeweils gewünschten Silo (2) eingefüllt.DESCRIPTION In processing and conveying systems, especially in Molding sand preparation systems in foundries are made Vorailos by a conveyor belt (1) or the like. The product is removed by mechanical scrapers (3) filled into the desired silo (2) from the conveyor belt.

Es sind Füllungsmelder bekannt, bei denen das Füllgut bei Erreichen eines bestimmten Füllstandes auf einen durch eine Membrane betätigten Mikto-Kontaktschalter einwirkt. Ferner sind Füllungmelder bekannt, bei denen die durch das Füllgut hervorgerufene Widerstands-oder Kapazitätsänderung zwischen einer in das Füllgut hineinragenden Meßsonde und der metallischen Wand des Silos über eine Brückenschaltung und einen elektronischen Verstärker oder dergl. den Füllstand anzeigt.Filling indicators are known in which the filling material is reached when it is reached of a certain level on a membrane-operated micro-contact switch acts. Furthermore, filling indicators are known in which the caused by the filling material Resistance or capacitance change between one that protrudes into the product Measuring probe and the metallic wall of the silo via a bridge circuit and a Electronic amplifier or the like. Indicates the level.

Es wird nun vorgeschlagen, die Sonde oder die Sonden (4) eines Silos (2) in den Eingang eines Meßverstärkers (5) zu legen, dessen Ausgang über ein Stellglied die Schütt@inrichtung des betr. Silos so lange in Tätigkeit setzt, bis der Sollwert des Füllstandes erreicht ist. Da der Meßteil derartiger Füllungsmelder verhältnismäßig kostspielig ist, wird ferner vorgeschlagen, bei größeren Anlagen die in den einzelnen Silos angebrachten Sonden in gleichbleibender Folge durch ein Schrittschaltwerk, Programmlaufwerk oder dergl. abzutasten. Hat ein Silo nicht den beabsichtigten Füllstand, so bleibt die entsprechende Sonde so lange am Verstärkereingang, bis über das gleichzeitig an den Verstärkerausgang gelegte Stellglied die betr. Fülleinrichtung den Füllstand des Silos wieder auf den Sollwert gebracht hat.It is now proposed to use the probe or probes (4) of a silo (2) to be placed in the input of a measuring amplifier (5), the output of which is via an actuator the dumping direction of the silo concerned is activated until the setpoint is reached the fill level is reached. Since the measuring part of such a level indicator is relatively is expensive, it is also proposed, in the case of larger systems, in the individual Silos attached probes in a constant sequence by a step switch, To scan program drive or the like. If a silo does not have the intended fill level, so the corresponding probe remains at the amplifier input until over the at the same time Actuator placed at the amplifier output the relevant filling device the level of the silo has brought it back to the target value.
