KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand vorliegender Erfindung bildet eine Formfüllvorrichtung für solche Maschinen zur Herstellung von Kunststeinen, insbesondere Cementsteinen, bei denen der Formkasten auf dem Maschinengestell vor- und zurückgefahren und auf diesem Wege mit Cementmörtel gefüllt, sowie das eingebrachte Material durch eine Walze eingeprefst wird.The subject of the present invention is a form filling device for such machines for the production of artificial stones, especially cement stones, where the molding box is on moved the machine frame back and forth and filled it with cement mortar in this way, as well as the introduced material is pressed in by a roller.
Es ist von dem Erfinder beim Arbeiten mit Maschinen dieser Art die Wahrnehmung gemacht worden, dafs die auf denselben hergestellten Kunststeine an einer Kante bezw. an einem Ende eine geringere Dichte und infolge dessen auch eine geringere Festigkeit besitzen als an dem anderen. Es rührt dies davon her, dafs beim Füllen des Formkastens, wie auch beim Einwalzen des Materials dieses von der Abstreichkante des Füllkastens sowie von der Prefswalze nach dem der Bewegungsrichtung entgegengesetzten Theile des vorwärtsgehenden Formkastens geschoben wird, so dafs der vordere Theil des letzteren entweder überhaupt nicht völlig ausgefüllt wird oder doch so wenig Material erhält, dafs beim Einpressen desselben dem Stein in diesem Theile nicht die erforderliche Dichte gegeben werden kann.It is made by the inventor when working with machines of this type the perception been that the artificial stones produced on the same bezw on one edge. at one end a lower density and as a result which also have a lower strength than the other. It stirs this from the fact that when filling the molding box, as well as when rolling in the material this from the scraping edge of the hopper and from the pref roller according to the direction of movement opposite parts of the forward molding box is pushed so that the anterior part of the latter is either not completely filled in at all or at least so little material is preserved that when it is pressed in, the stone in this part does not the required density can be given.
Diesem Uebelstande soll nach vorliegender Erfindung dadurch abgeholfen werden, dafs die Fülleinrichtung der Maschine mit einer Einrichtung versehen wird, welche sowohl der Abstreichkante des Füllkastens als auch der Bewegungsrichtung der Prefswalze entgegenarbeitet und dadurch das über dem Formkasten lagernde Material nach vorn bewegt.According to the present invention, this inconvenience is to be remedied by the fact that the filling device of the machine is provided with a device which both the The doctor edge of the filling box as well as the direction of movement of the Prefswalze counteracts and thereby moves the material stored over the molding box forward.
In der beiliegenden Zeichnung veranschaulicht Illustrated in the accompanying drawing
Fig. ι den in Frage kommenden Theil der Kunststeinformmaschine in der bisherigen Ausführung bei zum Theil unter dem Füllkasten hervorgezogenem Formkasten;Fig. Ι the relevant part of the Artificial stone forming machine in the previous version with partly under the filling box pulled out molding box;
Fig. 2 dasselbe mit der neuen Einrichtung zum Vorbewegen des Materials;Fig. 2 is the same with the new device for advancing the material;
Fig. 3 denselben Theil der Formmaschine mit unter der Prefswalze befindlichem Formkasten. 3 shows the same part of the molding machine with the molding box located under the pref roller.
Das Wesentliche der Erfindung besteht darin, dafs zwischen dem Formfüllkasten α und der Prefswalze b eine Walze d angeordnet ist, die von irgend einer geeigneten Stelle aus in einem der Drehrichtung der Prefswalze entgegengesetzten Sinne in Umdrehung versetzt wird und sich mit gröfserer Geschwindigkeit als der Formkasten g bewegt.The essence of the invention is that a roller d is arranged between the form filling box α and the pref roller b , which is set in rotation from any suitable point in a direction opposite to the direction of rotation of the pref roller and moves at a greater speed than the molding box g emotional.
Die Walze d kann hierbei auf dem Umfang gezahnt werden, wie dies beispielsweise in der Zeichnung angedeutet ist, oder als Bürste ausgebildet werden. In jedem Falle ist sie ebenso wie die Prefswalze b und die untere Vorderkante des Füllkastens der profilirten Oberfläche des herzustellenden Kunststeines anzupassen.The roller d can here be toothed on the circumference, as indicated, for example, in the drawing, or it can be designed as a brush. In any case, like the prefabricated roller b and the lower front edge of the filling box, it is to be adapted to the profiled surface of the artificial stone to be produced.
Aufserdem ist die Walze d so tief zu lagern, dafs dieselbe in die zum Zusammenpressen zugegebene, also über der Oberkante des Formkastens g lagernde Materialschicht hineinragen und letztere nach vorn hin höher aufschichten kann (s. Fig. 2),In addition, the roller d is to be stored so deep that it protrudes into the layer of material added for compression, i.e. that is stored above the upper edge of the molding box g, and the latter can be stacked higher towards the front (see Fig. 2),
Auf diese Weise wird der Formkasten auch unmittelbar hinter der vorderen Innenkante mit einer hohen Cementmörtelschicht versehen, so dafs, wenn er sich unter der Prefsvvalze b hindurchbewegt, letztere das Material auch im vorderen Theil des Formkastens entsprechend zusammendrücken kann und somit voll ausgeformte, sowie in allen Theileri gleich dichte Steine aus der Maschine hervorgehen.In this way, the molding box is provided with a high layer of cement mortar immediately behind the front inner edge, so that when it moves under the Prefsvvalze b , the latter can compress the material accordingly in the front part of the molding box and thus fully formed, as well as in all Theileri immediately dense stones emerge from the machine.
