Die vorliegende Erfindung bezieht sich auf eine Maschine zur Herstellung von Preßsteinen, Formstücken, wie Ziegel usw., bei welcher das Formgut in einem fortlaufenden Arbeitsgang in eine sich drehende, mehrere Formkammern enthaltende Formtrommel selbsttätig eingeschüttet, gepreßt und als fertiges Formstück ausgestoßen wird. 'The present invention relates to a machine for the production of pressed stones, Shaped pieces, such as bricks, etc., in which the shaped material is converted into a rotating, several in a continuous operation Forming drum containing molding chambers automatically poured in, pressed and finished Fitting is ejected. '
Bekannten Einrichtungen gegenüber unterscheidet sich die vorliegende dadurch, daß die Form, bevor sie sich unter den Fülltrichter einstellt, durch ein sich schnell drehen-.des Schaufelrad in ihrem Innern allseitig mit fein zerteiltem Sand beworfen wird, damit das - Preßgut beim Pressen" nicht an den Wandungen der Form festklebt. Auf der Zeichnung ist eine solche Maschine in beispielsweiser Ausführungsform dargestellt, und zwar zeigtThe present differs from known devices in that the shape, before it is positioned under the filling funnel, by rotating a fast-turning-.des The paddle wheel is pelted with finely divided sand on all sides so that the - Material to be pressed during pressing "does not stick to the walls of the mold. On the drawing such a machine is shown in an exemplary embodiment, namely shows
Fig. ι eine Seitenansicht der Maschine teilweise im Schnitt undFig. Ι a side view of the machine partially in section and
Fig. 2 eine Oberansicht der Sandzuführung.Fig. 2 is a top view of the sand feed.
In der bekannten Weise ist mit dem Trog a In the known way is with the trough a
der Trichter b verbunden, unter dem sich die sich drehende Formtrommel c bewegt. Die Böden der auf den Umfang der Trommel verteilten Preßformen d sind an Stangen /befestigt, die in Schlitten g der Trommelseitenwände geführt werden und die Böden in den Preßformen auf- und abwärts bewegen. Die Drehung der Trommel erfolgt den Formenabständen entsprechend schaltweise durch den Hebel w. Der Preßstempel / erhält seine Bewegung mittels einer von der Antriebswelle durch Arm q betätigten Schubstange m, während das Einstellen der Formenböden vermittels des Armes r mit Nasen s geschieht.connected to the hopper b , under which the rotating forming drum c moves. The bases of the compression molds d distributed over the circumference of the drum are attached to rods / which are guided in slides g of the drum side walls and move the bases up and down in the compression molds. The rotation of the drum takes place in accordance with the mold spacing by switching the lever w. The ram / receives its movement by means of a push rod m actuated by the drive shaft through arm q , while the mold bases are adjusted by means of the arm r with lugs s .
Das Einfüllen des Tones in die eingestellte Form geschieht durch ein Schaufelrad g, das sich unter dem Zuführungstrichter h, innerhalb des Trichters b, befindet.The filling of the clay into the set shape is done by a paddle wheel g, which is located under the feed hopper h, inside the hopper b .
Gemäß vorliegender Erfindung ist nun schräg oberhalb der Trommel c, vor der Füllstelle für die Formen ein Schaufelrad ν angeordnet, welchem aus der öffnung t eines Speisekanals mit Transportschnecke u Streu- ■ sand zugeführt wird. Diese erhält den Sand von einer Transportschnecke \. Beide zerteilen den Streusand in dünne Schichten.According to the present invention is now obliquely c above the drum, arranged in front of the filling point for the ν forms a paddle wheel, which from the opening t of a feeding channel with conveying screw u ■ scattering sand is supplied. This receives the sand from a transport screw \. Both divide the sand into thin layers.
Die Drehung- des Schaufelrades erfolgt ohne Unterbrechung und mit großer Geschwindigkeit, so daß der aus dem Speisekanal t austretende Sand fein zerstäubt gegen die bei der Trommeldrehung sich vorbeibewegende Form geworfen wird. Da die. Form hierbei nach und nach alle ihre inneren Flächen dem Sandstrom darbietet, so wird sie überall gleichmäßig besandet, und zwar geschieht dieses, bevor die betreffende Form unter den Fülltrichter b gelangt,The rotation of the paddle wheel takes place without interruption and at great speed, so that the sand emerging from the feed channel t is thrown finely atomized against the form moving past during the rotation of the drum. Since the. The shape gradually presents all of its inner surfaces to the stream of sand, so it is sanded evenly everywhere, and this happens before the shape in question gets under the hopper b ,
