Description

Die Erfindung betrifft eine Vorrichtung zur Messung der Schwindung von Tonformlingen und ist dadurch gekennzeichnet, daß die Vorrichtung zwei Messerschneiden zum Einstecken in die Formlinge und eine sich auf diese abstützende adhäsi.erende Rolle aufweist, welche beim Schwinden des Formlings blewegt und deren Bewegung über ein Gestänge auf ein schreibendes Registriergerät übertragen wird. The invention relates to a device for measuring shrinkage of clay moldings and is characterized in that the device has two knife edges for insertion into the moldings and an adhesive end that is supported on them Has role, which blewegt when the molding shrinks and its movement over a linkage is transferred to a writing recorder.

Ein Tonformling erfährt bei der Trocknung einerseits eine Gewichtsabnahme infolge Verdunstung des Wassers und andererseits eine Volumenverkleinerung, die man als Schwindung bezeichnet. Zwischen den beiden Vorgängen besteht für leinen gegebenen Ton eine ganz bestimmte Beziehung, so daß es genügt, die Schwindung durch Meßgeräte zu registrieren, um übler das Verhalten des Formlings auf seinem Weg durch die Trockenanlage orientiert zu sein. Zu diesem Zweck läßt sich die erfindungsgemäße Meßvorrichtung verwenden. On the one hand, a clay molding experiences a weight loss during drying as a result of evaporation of the water and, on the other hand, a reduction in volume, which is called shrinkage. There is a line between the two processes given tone a very definite relationship, so that it is sufficient to pass through the shrinkage Register measuring devices in order to worsen the behavior of the molding on its way through to be oriented towards the drying plant. For this purpose, the invention Use measuring device.

In der Zeichnung ist eine Ausführungsform der Erfindung veranschaulicht. An embodiment of the invention is illustrated in the drawing.

Auf dem Formling I liegt das Instrument so auf. daß auf der einen Seite der Meßstrecke die mit dem Instrument fest verbundenen Schneiden oder zwei Spitzen 2 in den Formling eindringen und auf der anderen Seite die Rolle 3 auf dem Formling aufliegt. Zweckmäßig sind diole zur Auflage dienenden zwei Spitzen 2 und die Rolle 3 in Dreieckform angeordnet. Bleim Schwinden des Formlings dreht sich die Rolle 3, und deren Drehung wird über das Gestränge 4, 5, 6 und 7 auf die Schreibfeder 8 üb.ertragen, so daß sich diese nach oben oder nach unten bewegt und dadurch eine Schwindkurve g auf das auf der Schreibtrommel 10 aufgespannte Registrierpapier 11 aufzeichnet. je nach der Dauer des Trockenprozesses wird die Umfangsgeschwindigkeit der Schreib trommel bemessen und lein Registrierpapier mit entsprechendem Zeitaufdruck verwendet. The instrument rests on the molding I. that on the one hand Side of the measuring section the cutting edges or two that are firmly connected to the instrument Tips 2 penetrate into the molding and on the other side the roller 3 on the Molding rests. Appropriate are diols serving for the support two tips 2 and the roller 3 arranged in a triangular shape. Lead turns as the molding shrinks the roller 3, and its rotation is controlled by the rods 4, 5, 6 and 7 on the pen 8 so that it moves up or down and thereby a Shrinkage curve g on the recording paper 11 stretched on the writing drum 10 records. depending on the duration of the drying process, the peripheral speed Measure the writing drum and use linen recording paper with the appropriate time stamp used.
