Description

Das Hauptpatent betrifft ein Verfahren sowie eine Vorrichtung zum Herstellen von keramischen Platten aus einem flachgezogenen Ton­strang. Bei dem Verfahren werden die von dem Tonstrang abgeschnit­tenen Strangstücke zunächst bis zu einem die Trockenschwindung nahe­zu beendenden, aber noch verformbaren Zustand vorgetrocknet, dann die keramischen Platten aus den so vorgetrockneten Strangstücken ge­stanzt und anschließend getrocknet.The main patent relates to a method and a device for producing ceramic plates from a flat-drawn clay strand. In the process, the strand pieces cut from the clay strand are first predried to a state which almost completely ends the drying shrinkage but is still deformable, then the ceramic plates are punched out of the predried strand pieces and then dried.

Die Vorrichtung zur Durchführung dieses Verfahrens enthält einen Strangabschneider, einen Ausstanzer für keramische Platten und eine Einrichtung zum Umsetzen der keramischen Platten auf einen Trockner durchlaufende Trocknerroste und ist dadurch gekennzeichnet, daß zwi­schen dem Strangabschneider und dem Ausstanzer ein erster Durch­laufofen als Vortrockner angeordnet und hinter dem Ausstanzer ein zweiter Durchlaufofen als Fertigtrockner vorgesehen ist.The device for carrying out this method contains a strand cutter, a punch for ceramic plates and a device for converting the ceramic plates to a dryer grate running through the dryer and is characterized in that a first continuous furnace is arranged as a pre-dryer between the strand cutter and the punch and behind the punch a second continuous furnace is provided as a finished dryer.

Dabei werden die Strangstücke vom Strangförderer auf eine den Vor­trockner vorgeordnete Sammel- und Beschickungseinrichtung für den Transport von Strangstückreihen durch den Vortrockner umgesetzt und von einer diesem nachgeordneten Sammel- und Beschickungseinrich­tung auf einen durch den Ausstanzer hindurchgehenden Förderer ein­zeln umgeladen.The strand pieces are transferred from the strand conveyor to a collecting and loading device upstream of the pre-dryer for the transport of rows of strand pieces through the pre-dryer and individually reloaded from a downstream collecting and loading device onto a conveyor passing through the punch.

Aufgabe der Zusatzerfindung ist es, die Vorrichtung nach dem Haupt­patent flexibler zu gestalten.The object of the additional invention is to make the device according to the main patent more flexible.

Diese Aufgabe wird mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in the characterizing part of claim 1.

Durch die erfindungsgemäße Ausführung des Vortrockners ist es mög­lich, die Strangstücke je nach Bedarf mit oder ohne Benutzung des Paternosteraufzugs durch den Vortrockner zu führen. Bei einer Benut­zung des Paternosteraufzugs wird dieser zu einem Puffer, wodurch die Kapazität des Vortrockners erhöht wird.The inventive design of the pre-dryer makes it possible to pass the strand pieces through the pre-dryer with or without using the paternoster lift as required. When the paternoster lift is used, it becomes a buffer, which increases the capacity of the pre-dryer.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden beschrieben.An embodiment is shown in the drawing and is described below.

Der aus einer Strangpresse austretende flache Tonstrang wird mit einem Abschneider 3 zu Strangstücken 4 geschnitten, welche über eine als Rollen- oder Bandförderer unmittelbar gebildete Zuführung 15 dem mit dieser fluchtenden Vortrockner 6 zugeführt werden. Im Vortrockner 6 befinden sich eine aus zwei Abschnitten 16, 16′ be­stehende Rollenbahn sowie ein Paternosteraufzug mit Sätzen von übereinander angeordneten Rechen 17, deren Zinken 18 die Rollen­bahn durchgreifen. Im Betrieb nehmen die Zinken 18 eines jeden Rechens 17 jeweils ein Strangstück 4 vom Abschnitt der Rollenbahn 16 ab. Nach Beladen der Rechen 17 eines jeden Satzes werden diese durch den Vortrockner 6 bewegt. Die Rechensätze werden nach dem Vortrocknen der Strangstücke entleert, wobei die Strangstücke einzeln nacheinander auf dem Abschnitt 16′ der Rollenbahn abge­legt und über den Förderer 7 dem Ausstanzer 8 zugeführt werden.The flat clay strand emerging from an extrusion press is cut with a cutter 3 into strand pieces 4, which are fed to the pre-dryer 6 aligned with this via a feed 15 formed directly as a roller or belt conveyor. In the pre-dryer 6 there are a two sections 16, 16 'existing roller conveyor and a paternoster elevator with sets of rakes 17 arranged one above the other, the prongs 18 penetrate the roller conveyor. In operation, the tines 18 of each rake 17 each remove a strand 4 from the section of the roller conveyor 16. After loading the rakes 17 of each set, they are moved through the pre-dryer 6. The computation sets are emptied after the pre-drying of the strand pieces, the strand pieces being deposited one after the other on section 16 'of the roller conveyor and fed to the punch 8 via the conveyor 7.

Bei Nichtgebrauch des Paternosteraufzugs wird dieser in einer Stellung festgehalten, in der die Strangstücke 4 auf den beiden Rollenbahnabschnitten unbehindert durchlaufen können. Die bei­den Rollenbahnabschnitte sind unabhängig voneinander antreibbar. Die Abschnitte 16 und 16′ der Rollenbahn können entweder unmit­telbar aneinander anschließen oder durch ein Zwischenband 19 miteinander verbunden sein. Die Rechen 17 laufen in Geradefüh­rungen um und werden mittels endloster Ketten im Kreislauf be­wegt.When the paternoster lift is not in use, it is held in a position in which the strand pieces 4 can pass freely on the two roller conveyor sections. The two roller conveyor sections can be driven independently of one another. The sections 16 and 16 'of the roller conveyor can either connect directly to one another or be connected to one another by an intermediate belt 19. The rakes 17 run in straight guides and are circulated by means of endless chains.
