Description
Verfahren und Vorrichtung zur Einstellung der Füllhöhe an Pressen für keramische Formlinge Die Hauptpatentanmeldung behandelt ein Verfahren zur automatischen Einstellung der Füllhöhe an Pressen für keramische Formlinge, bei denen Formboden-und Formrahmen relativ zueinander verschiebbar sind, wobei die Verstellung, insbesondere des Formbodens, bei jedem Arbeitsspiel der Presse um eine festgelegte, die Füllhöhe vergrößernde oder verkleinernde Strecke erfolgt und die Verstellbewegung bei Überschreitung eines voreingestellten Maximal-bzw. Unterschreitung eines Minimalpreßdrucks oder Über- bzw. Unterschreitung eines Maximal- bzw. Minimalabstandes zwischen Formboden und Preßstempelstirnfläche umgekehrt wird. Die Anwendung dieses Verfahrens an Drehtischpressen führt deshalb zu Schwierigkeiten, weil sich je nach Ausbildung der Presse zwischen der Füllstellung und der Preßstellung zwei, drei oder mehr bereits gefüllte Formen befinden. Bei normaler Arbeitsweise der Füllhöhenverstellvorrichtung nach der Hauptpatentanmeldung würde bei beispielsweise drei zwischen der Füllhöheneinstellung und der Preßstellung liegenden Formen die Korrektion der Füllhöhe durch den Verstellmotor dreimal hintereinander von falschen Bezugswerten aus vorgenommen, so daß der Regelbereich für die Herstellung deich dichter Erzeugnisse zu groß wird.Method and device for adjusting the filling level in presses for ceramic moldings The main patent application deals with a method for automatic Adjustment of the filling level on presses for ceramic briquettes, in which mold bottom and Mold frames are displaceable relative to one another, the adjustment, in particular of the mold bottom, with each work cycle of the press by a fixed, the filling level increasing or decreasing distance takes place and the adjustment movement when exceeded of a preset maximum or Falling below a minimum pressure or Exceeding or falling below a maximum or minimum distance between the bottom of the mold and ram face is reversed. The application of this process to rotary table presses leads to difficulties because, depending on the training of the press, between the filling position and the pressing position two, three or more already filled forms are located. With normal operation of the level adjusting device according to the main patent application For example, three would be between the level setting and the pressing position lying forms the correction of the filling level by the adjusting motor three times in a row made from incorrect reference values, so that the control range for the manufacture dyke dense products become too big.
Zur Vermeidung der aus dieser Tatsache herrührenden Differenzen soll die Verstellbewegung nach der Erfindung bei Anwendung des Verfahrens nach der Hauptpatentanmeldung an Drehtischpressen jeweils nur einmal während einer Hubzahl der Presse erfolgen, die der Anzahl der Formen entspricht, die sich zwischen Füll- und Preßstellung befinden. Auf diese Weise wird erreicht, daß stets nur der Füllungszustand der ersten Form der zwischen Füll- und Preßstellung befindlichen Formengruppe für das Arbeiten der Regelvorrichtung bestimmend ist.In order to avoid the differences resulting from this fact the adjustment movement according to the invention when using the method according to the main patent application on rotary table presses only once during a number of press strokes, which corresponds to the number of forms that are between the filling and pressing positions. In this way it is achieved that only the filling state of the first form the group of molds located between the filling and pressing positions for working the Control device is determinative.
Als Vorrichtung zur Durchführung des Verfahrens kann ein Untersetzungsgetriebe dienen, das an der Kurbelwelle der Presse angeordnet ist und beispielsweise bei Vorhandensein von drei Formen -zwischen Füll- und Preßstellung eine Scheibe mit einem Drehzahlverhältnis von 1 :3 antreibt. Die Scheibe beeinflußt dann über auf ihr angeordnete Anschläge die Schalteinrichtung für die Hubverstellvorrichtung.A reduction gear can be used as the device for carrying out the method serve, which is arranged on the crankshaft of the press and, for example, at Presence of three forms -between filling and pressing position with a disc drives a speed ratio of 1: 3. The disc then affects over on her arranged stops the switching device for the stroke adjustment device.
