Description

Die Erfindung betrifft ein Verfahren zum Auswerfen von Dachziegelformlingen aus den Preßformen mittels zwischen die Preßflächen und die Formlinge geblasener Druckluft.The invention relates to a method for ejecting shaped roof tiles from the molds by means of blown between the pressing surfaces and the moldings Compressed air.

Es ist bekannt, einen von dem Luftkanalsystem der Preßformen getrennten Luftzuführungskanal im Takt der Presse während-> des Ausblasvorganges an den Luftkanal der Preßformen anzuschließen, wobei für diesen Zeitraum die Preßluft für das Ausblasen wirksam wird. Es ist weiterhin bekannt, an Töpfereimaschinen eine Form mit einer Druckluftzuführung unmittelbar zu verbinden und diese während des Auswerfens zu öffnen und zu schließen.It is known to separate one of the air duct system of the compression molds Air supply duct in the cycle of the press during-> the blowing process to the air duct to connect the molds, the compressed air for the blowing out for this period takes effect. It is also known to have a shape with a pottery machine To connect compressed air supply directly and this during ejection open and close.

Die Vorrichtung nach der Erfindung unterscheidet sich von den bekannten Vorrichtungen dadurch, daß eine Reihe von Formen unmittelbar mit einer zentralen Luftzuführung verbunden wird, wobei die Verbindung zwischen der zentralen Luftzuführung und den Formen durch Absperrvorrichtungen unterbrochen ist, die im Takt der Presse und in der Reihenfolge der Formen das Einströmen der Druckluft in die jeweilige Form für die Dauer des Ausblasvorganges freigeben. Der Vorteil dieser Einrichtung liegt darin, daß alle beweglichen Teile an der Außenwand der Presse liegen, wo sie mit dem Ton nicht in Berührung kommen und damit nicht der Gefahr der Verschmutzung und des Verstopfens ausgesetzt sind.The device according to the invention differs from the known ones Devices by making a series of shapes directly with a central Air supply is connected, the connection between the central air supply and the molds is interrupted by shut-off devices, which are in time with the press and in the order of the shapes the influx of compressed air into the respective Release the mold for the duration of the blow-out process. The advantage of this facility is that all moving parts are on the outside wall of the press where they are do not come into contact with the clay and thus do not run the risk of pollution and are subject to clogging.

In den Abbildungen ist ein Ausführungsbeispiel einer Vorrichtung zur Ausübung des Verfahrens nach derErfindung an einerRevolverpresse schematisch dargestellt. Das Verfahren kann auch an anderen Pressenarten vorteilhaft Verwendung finden.In the figures is an embodiment of a device for Implementation of the method according to the invention on a turret press shown schematically. The process can also be used to advantage on other types of presses.

Abb. i zeigt einen Querschnitt. durch die Trommel der Presse in Linie A-B der Abb. 2; Abb. 2 zeigt einen Längsschnitt in der Linie C-D der- Abb. i und Abb. 3 ein Ansicht aus der Richtung E der Abb. 2.Fig. I shows a cross section. through the drum of the press in line A-B of Fig. 2; Fig. 2 shows a longitudinal section along the line C-D of Figs. I and Fig. 3 is a view from the direction E of Fig. 2.

Wie die Abb. i zeigt, sind die auf der Trommel T aufgeschraubten Formen F mit je einer ihr zugehörigen Luftleitung i verbunden. Die Verbindung der Luftleitungen mit den Formen, erfolgt durch ein elastisches Zwischenstück 2, gegen das sich eine an der Unterseite der Form angeordnete Öffnung der Form andrückt. Diese Öffnung ist gegen die Preßflächen der Form durch ein in der Abbildung nur angedeutetes Ventil 3 in bekannter Weise geschlossen. .Die Verbindung der Formen mit den Luftleitungen i kann auch an anderer Stelle und auf andere Weise erfolgen. Die Luftleitungen i sind mittels der Durchbohrungen 4 in der Welle W nach außen geführt und münden an der Stirnfläche der Welle W in der Ausdrehung einer Kappe 5, in welche die zentrale Luftzuführung 6 mündet. Die Kappe 5 ist schleifend auf den Wellenstumpf aufgesetzt und gegen diesen abgedichtet. Sie steht still, während die Welle sich dreht.As Fig. I shows, the forms screwed onto the drum are T. F each connected to an associated air line i. The connection of the air lines with the forms, takes place through an elastic intermediate piece 2, against which a on the underside of the mold arranged opening of the mold presses. This opening is against the pressing surfaces of the mold by a valve only indicated in the figure 3 closed in a known manner. The connection of the forms with the air ducts i can also be done elsewhere and in a different way. The air lines i are guided to the outside by means of the through-holes 4 in the shaft W and open out the end face of the shaft W in the recess of a cap 5, in which the central Air supply 6 opens. The cap 5 is placed on the stub shaft in a dragging manner and sealed against it. It stands still while the shaft turns.

Im Wellenstumpf sind in die Luftleitung 4 einer jeden Form Absperrvorrichtungen, z. B. die Schieber 7, eingebaut, die über das Gestänge 8 mittels des Nockens 9 von der Antriebswelle io der Presse her im Takt der Presse das Einströmen der Preßluft in die Formen für die Dauer des Auswerfvorganges der Reihe nach freigeben.In the stub shaft there are shut-off devices in the air line 4 of each shape, z. B. the slide 7, installed, which via the linkage 8 by means of the cam 9 of the drive shaft io the press ago the flow of compressed air in the cycle of the press release into the molds one after the other for the duration of the ejection process.
