Description

Die Erfindung betrifft ein Verfahren zum automatisierten Befüllen einer Form mit flüssi­ gem Metall nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for the automated filling of a mold with liquid gem metal according to the preamble of claim 1.

Bei derartigen allgemein bekannten Verfahren erfolgt die Kippbewegung des Gießlöf­ fels und die davon abhängige Geschwindigkeit beim Eingießen nach einer festpro­ grammierten Abfolge. Bilden sich Oxidationseinschlüsse, kann die festprogrammierte Abfolge zu stark schwankenden Pegel im Eingußstutzen führen, die die Qualität des Prozesses nachteilig beeinflussen. Im Extremfall kann es zu einem Überlaufen von Flüssigmetall im Bereich des Eingußstutzens kommen.In such generally known methods, the pouring movement of the pouring spout takes place rock and the dependent speed when pouring after a fixed grammed sequence. If oxidation inclusions form, the permanently programmed one can Sequence lead to strongly fluctuating levels in the pouring spout, which affect the quality of the Adversely affect the process. In extreme cases, it can overflow Liquid metal come in the area of the pouring spout.

Es stellt sich die Aufgabe, ein Verfahren der eingangsgenannten Art anzugeben, bei dem der Pegel im Eingußstutzen innerhalb einer vorgebbaren Bandbreite konstant bleibt.The task is to specify a method of the type mentioned at the outset which the level in the pouring spout is constant within a specifiable bandwidth remains.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale.This object is achieved according to the invention by those specified in claim 1 Characteristics.

Danach wird die Füllstandshöhe im Eingußstutzen kontinuierlich überwacht. Abwei­ chungen von einer vorgebbaren Schwankungsbreite werden in die Steuerung der Kipp­ bewegung des Gießlöffels einbezogen und bewirken eine Verlangsamung oder Be­ schleunigung der Kippbewegung. Die dadurch verkleinerte oder vergrößerte Menge an Flüssigmetall führt zur Einregulierung des Pegels im Eingußstutzen innerhalb der vor­ gegebenen Bandbreite.Then the fill level in the pouring spout is continuously monitored. deviate Conversions of a predeterminable fluctuation range are in the control of the tipping Movement of the spoon included and cause a slowdown or Be acceleration of the tilting movement. The thereby reduced or enlarged amount of  Liquid metal leads to the regulation of the level in the pouring spout within the given bandwidth.

Vorzugsweise wird zur Überwachung des Füllstandes ein Laser-Sensor eingesetzt, um den unmittelbaren Kontakt mit dem Flüssigmetall zu vermeiden.A laser sensor is preferably used to monitor the fill level to avoid direct contact with the liquid metal.

Anhand eines Ausführungsbeispieles und der schematischen Fig. 1 und 2 wird das er­ findungsgemäße Verfahren beschrieben.Using an exemplary embodiment and the schematic FIGS. 1 and 2, the method according to the invention is described.

Dabei zeigt dieThe shows

Fig. 1 einen Schmelztiegel, in dessen Flüssigmetallfüllung ein Gießlöffel eintaucht und Fig. 1 is a melting pot, in the liquid metal filling a spoon is immersed and

Fig. 2 einen Gießroboter während der Kippbewegung des Gießlöffels mit einer Form. Fig. 2 shows a casting robot during the tilting movement of the ladle with a mold.

Die Fig. 1 zeigt einen Schmelztiegel 1, der mit flüssigem Metall 2 gefüllt ist. Eine an ei­ nem Arm 3 eines Gießroboters 4 befestigter Gießlöffel 5 taucht gerade in das Flüssig­ metall ein, um einen Teil davon aufzunehmen. Fig. 1 shows a crucible 1 which is filled with liquid metal 2. A spoon 5 attached to an arm 3 of a casting robot 4 is just immersed in the liquid metal to take up a part of it.

Die Fig. 2 zeigt eine Form 6 mit Eingußstutzen 7 und einem Steiger 8. Oberhalb des Eingußstutzens 7 ist mit Hilfe des Gießroboters 4 der mit Flüssigmetall gefüllte Gießlöf­ fel 5 positioniert. Durch Einleiten einer Kippbewegung des Gießlöffels fließt über den Eingußstutzen Flüssigmetall in die Form. Nachdem der Pegelstand im Eingußstutzen 7 erstmals die Sollhöhe erreicht hat, erfolgt die Steuerung der Kippbewegung des Gieß­ löffels und damit die Fließgeschwindigkeit des Flüssigmetalls durch Koppelung der mit einem Lasersensor 9 ermittelten Füllstandswerte mit der Steuereinrichtung des Gieß­ roboters 4 für die Kippbewegung des Gießlöffels 5. Fig. 2 shows a mold 6 having Eingußstutzen 7 and a riser. 8 Above the pouring spout 7 , the pouring spoon 5 filled with liquid metal is positioned with the aid of the casting robot 4 . By initiating a tilting movement of the pouring spoon, liquid metal flows into the mold via the pouring spout. After the water level in the pouring spout 7 has reached the desired height for the first time, the tilting movement of the pouring spoon is controlled and thus the flow rate of the liquid metal by coupling the level values determined with a laser sensor 9 to the control device of the pouring robot 4 for the tilting movement of the pouring spoon 5 .
