Description

Die Erfindung betrifft eine Tonstrang-Schneidevorrichtung gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a clay strand cutting device according to the preamble of patent claim 1.

Mit derartigen Tonstrang-Schneidevorrichtungen werden aus einem von einer Strangpresse kommenden Strangstück, das während des Schneidens quer zur Stranglaufrichtung gefördert wird, Formlinge geschnitten. Je nach Lochung sind die Strangstücke quer zur Stranglaufrichtung oftmals sehr empfindlich gegen Druck. Zur Gewährleistung einer flexiblen Fertigung ist es außerdem notwendig, eine Tonstrang-Schneidevorrichtung schnell auf verschiedene Ziegelgrößen einstellen zu können. Dazu ist es erforderlich, die Fördereinrichtungen und auch die Schneidedrahthalter auszuwechseln.With such clay strand cutting devices, moldings are cut from a strand piece coming from an extrusion press, which is conveyed during the cutting transverse to the direction of the strand. Depending on the perforation, the strand pieces transverse to the direction of the strand are often very sensitive to pressure. To ensure flexible production, it is also necessary to be able to quickly adjust a clay strand cutting device to different brick sizes. To do this, it is necessary to replace the conveyor devices and also the cutting wire holders.

Aus der DE-PS 22 20 360 ist eine Tonstrang-Schneidevorrichtung mit mehreren untereinander Zwischenräume aufweisenden Förderbändern, auf welchen der Tonstrang gelagert ist und mit mehreren voneinander beabstandeten, sich quer zur Strangrichtung erstreckenden Schneidedrähten, die mittels Drahthaltern von einem Schneiderahmen geführt werden, bekannt, wobei die Schneidedrähte während des Schneidevorgangs in die Zwischenräume zwischen den Förderbändern eintauchen. Dabei ist der Schneiderahmen an einer Seite schwenkbar gelagert, so daß die Schneidedrähte eine Drehbewegung um die Schwenkachse ausführen.From DE-PS 22 20 360 a clay strand cutting device with a plurality of interspacing conveyor belts on which the clay strand is mounted and with a plurality of spaced apart cutting wires extending transversely to the strand direction, which are guided by means of wire holders from a cutting frame, is known. wherein the cutting wires are immersed in the spaces between the conveyor belts during the cutting process. The cutting frame is pivotally mounted on one side so that the cutting wires perform a rotary movement about the pivot axis.

Nachteilig ist dabei, daß große Formlinge sehr lange Drähte erfordern, die leicht zum Reißen neigen, oder sehr steil gestellte Schneidedrähte, die beim Anschnitt auf den Tonstrang in horizontaler Richtung unerwünscht Druck ausüben.The disadvantage here is that large moldings require very long wires that tend to tear, or very steep cutting wires that undesirably exert pressure in the horizontal direction when they are cut onto the clay strand.

Aus der Lingl-Information 77/93 (Titelbild) ist eine Tonstrang-Schneidevorrichtung bekannt, bei der mit Abstand zueinander angeordnete Schneidedrähte von einem an beiden Seiten in vertikaler Richtung verschiebbaren Schneiderahmen geführt werden. Dabei führen die Schneidedrähte eine ausschließlich vertikale Schnittbewegung aus und tauchen in die Zwischenräume zwischen den nebeneinander angeordneten Fördereinrichtungen ein. Eine Seite des Schneiderahmen ist über und die andere unter dem Schneidetisch gelagert, wobei die Drähte am unter dem Schneidetisch befindlichen Ende an durch die Lücken zwischen den Transportbändern greifenden Armen befestigt sind.A clay strand cutting device is known from Lingl Information 77/93 (title picture), in which cutting wires arranged at a distance from one another are guided by a cutting frame which can be displaced in the vertical direction on both sides. The cutting wires perform an exclusively vertical cutting movement and plunge into the spaces between the conveyor devices arranged next to each other. One side of the cutting frame is supported above and the other under the cutting table, the wires at the end under the cutting table being fastened to arms which pass through the gaps between the conveyor belts.

Nachteilig bei dieser Vorrichtung ist, daß die Drähte durch die vertikale Schnittbewegung zu großen Druck auf den Tonstrang ausüben. Ein weiterer Nachteil liegt darin, daß das Wechseln von Förderbändern und Schneiderahmen, die innerhalb der vertikalen Führung mittig gelagert sind, sehr aufwendig ist.A disadvantage of this device is that the wires exert excessive pressure on the clay strand due to the vertical cutting movement. Another disadvantage is that the changing of conveyor belts and cutting frames, which are mounted centrally within the vertical guide, is very complex.

Aufgabe der Erfindung ist es daher, eine Tonstrang-Schneidevorrichtung zu schaffen, bei der die Schneidedrahtführung derart erfolgt, daß der Schneidedruck vermindert wird.The object of the invention is therefore to provide a clay strand cutting device in which the cutting wire is guided in such a way that the cutting pressure is reduced.

Eine weitere Aufgabe der Erfindung liegt darin, eine Tonstrang-Schneidevorrichtung zu schaffen, bei der ein Auswechseln von Fördereinrichtung und Schneiderahmen zum Übergang auf ein anderes Ziegelformat in einfacher Weise ermöglicht wird.Another object of the invention is to provide a clay-strand cutting device in which an exchange of the conveyor and the cutting frame for the transition to another brick format is made possible in a simple manner.

Die Aufgabe wird erfindungsgemäß gelöst durch eine Tonstrang-Schneidevorrichtung mit mehreren untereinander Zwischenräume aufweisenden, einen Schneidetisch bildenden Fördereinrichtungen, auf denen der Tonstrang aufliegt und mit mehreren voneinander beabstandeten, sich quer zur Strangrichtung erstreckenden Schneidedrähten, die an ihren beiden Enden jeweils von einem ersten Drahthalter und einem zweiten Drahthalter in einem Schneiderahmen gehalten werden, wobei die Schneidedrähte während des Schnitts in die Zwischenräume zwischen den Fördereinrichtungen eintauchen, dadurch gekennzeichnet, daß die Schneidedrähte durch den Schneiderahmen mit den Drahthaltern so geführt werden, daß die Schneidedrähte mit der vertikalen Schnittbewegung gleichzeitig eine Bewegung entlang ihrer Längsachse ausführen.The object is achieved according to the invention by a clay strand cutting device with a plurality of interspacing conveyor devices forming a cutting table, on which the clay strand rests and with a plurality of spaced apart cutting wires extending transversely to the strand direction, each of which has a first wire holder and a second wire holder are held in a cutting frame, the cutting wires being immersed in the spaces between the conveyors during the cutting, characterized in that the cutting wires are guided through the cutting frame with the wire holders so that the cutting wires simultaneously move along the vertical cutting movement run along its longitudinal axis.

Ein Vorteil der erfindungsgemäßen Tonstrang-Schneidevorrichtung liegt darin, daß durch die sägeschnittartige Bewegung der Schneidedruck wesentlich verringert wird und auch empfindlichere Hohlware einwandfrei geschnitten werden kann.An advantage of the clay strand cutting device according to the invention is that the cutting pressure-like movement significantly reduces the cutting pressure and even more sensitive hollow goods can be cut perfectly.

In Anspruch 2 wird eine erfindungsgemäße Tonstrang-Schneidevorrichtung beschrieben, bei der sich während des Schnitts der Schnittwinkel ändert.In claim 2, a clay strand cutting device according to the invention is described, in which the cutting angle changes during the cutting.

In den Ansprüchen 3 und 4 sind konstruktive Ausgestaltungen einer erfindungsgemäßen Tonstrang-Schneidevorrichtung beschrieben.In the claims 3 and 4, constructive configurations of a clay strand cutting device according to the invention are described.

In Anspruch 5 ist eine erfindungsgemäße Schneidevorrichtung dargestellt, bei der die ersten Drahthalter und die zweiten Drahthalter in Anschnittposition über dem Schneidetisch angeordnet sind. Der Vorteil liegt darin, daß auch ohne den Einsatz übermäßig langer Schneidedrähte großformatige Tonstränge geschnitten werden können, wobei keine unerwünscht starken horizontalen Kräfte auf den Tonstrang ausgeübt werden.In claim 5, a cutting device according to the invention is shown, in which the first wire holder and the second wire holder in the gate position above the Cutting table are arranged. The advantage is that large-format clay strands can be cut without the use of excessively long cutting wires, with no undesirably strong horizontal forces being exerted on the clay strand.

Im Anspruch 6 werden weitere konstruktive Ausgestaltungen der erfindungsgemäßen Tonstrang-Schneidevorrichtung beschrieben, deren Vorteil insbesondere darin liegt, daß die den Schneidetisch bildenden Fördereinrichtungen und der am Schneidetisch gelagerte Schneiderahmen räumlich klein, leicht zugänglich und deshalb mit wenigen Griffen austauschbar sind.In claim 6 further constructive embodiments of the clay strand cutting device according to the invention are described, the advantage of which is in particular that the conveyor devices forming the cutting table and the cutting frame mounted on the cutting table are spatially small, easily accessible and therefore interchangeable with a few handles.

Ein von einer Strangpresse (nicht dargestellt) kommendes Strangstück 1 liegt auf den als Schneidetisch 2 dienenden Fördereinrichtungen 2a auf, die aus mehreren, jeweils Zwischenräume aufweisenden Förderbändern bestehen können, wobei das Strangstück 1 senkrecht zur Förderrichtung der Förderbänder liegt. Mehrere Schneidedrähte sind mittels Drahthaltern 5, 10 durch einen Schneiderahmen 4 so gehalten, daß sie beim Schnitt in die Zwischenräume zwischen die einzelnen Förderbändern 2a eintauchen. Der Schneiderahmen 4 ist an einer Seite drehbar an einem in einer vertikalen Führungsschiene 7 bewegbaren Führungskörper 9 gelagert. Die andere Seite des Schneiderahmens 4, die sich unterhalb der Fördereinrichtungen 2a befindet, ist über ein Gelenk drehbar an einem Hebel 6 befestigt, der wiederum schwenkbar mit dem Schneidetisch 2 verbunden ist.A strand 1 coming from an extrusion press (not shown) rests on the conveyor devices 2a serving as a cutting table 2, which can consist of several conveyor belts, each with gaps, the strand 1 lying perpendicular to the conveying direction of the conveyor belts. A plurality of cutting wires are held by means of wire holders 5, 10 by means of a cutting frame 4 such that they are immersed in the spaces between the individual conveyor belts 2a during the cut. The cutting frame 4 is rotatably supported on one side on a guide body 9 which is movable in a vertical guide rail 7. The other side of the cutting frame 4, which is located below the conveyor devices 2a, is rotatably attached via a joint to a lever 6, which in turn is pivotally connected to the cutting table 2.

Die Tonstrang-Schneidevorrichtung wird durch einen Hubantrieb (nicht gezeigt), der ein Kurbelantrieb oder ein Linearmotor sein kann und am Führungskörper 9 angreift, angetrieben. Beim Absenken des Schneiderahmens 4 wird, wie am besten aus Figur 4 zu entnehmen ist, durch die Verschwenkung des Hebels 6 der Schneiderahmen 4 so bewegt, daß die Schneidedrähte 3 eine ziehende Bewegung in horizontaler Richtung ausführen, wodurch der Widerstand beim Schnitt wesentlich verringert wird. Gleichzeitig ändert sich während des Schnitts der Schnittwinkel der Schneidedrähte 3.The clay strand cutting device is driven by a lifting drive (not shown), which can be a crank drive or a linear motor and engages on the guide body 9. When the cutting frame 4 is lowered, as can best be seen in FIG. 4, the pivoting of the lever 6 moves the cutting frame 4 in such a way that the cutting wires 3 perform a pulling movement in the horizontal direction, as a result of which the resistance during cutting is substantially reduced. At the same time, the cutting angle of the cutting wires 3 changes during the cutting.

Wie am besten aus Figur 4 zu entnehmen ist, bewegt sich dabei der in der Zeichnung rechts dargestellte erste Drahthalter 5 allein in vertikaler Richtung, während der im Bild links dargestellte zweite Drahthalter 10 in einer Kurvenbahn K geführt wird. Die Schneidedrähte 3 führen daher eine sägeschnittartige Bewegung gegenüber dem Tonstrang 1 aus, die den zum Schneiden erforderlichen Schneidedruck deutlich verringert.As can best be seen from FIG. 4, the first wire holder 5 shown on the right in the drawing moves solely in the vertical direction, while the second wire holder 10 shown on the left is guided in a curved path K. The cutting wires 3 therefore perform a saw-cut-like movement with respect to the clay strand 1, which significantly reduces the cutting pressure required for cutting.

Man erkennt außerdem, daß die Drahthalter 5, 10 so angeordnet sind, daß beim Schneiden auch großformatiger Strangstücke der Anschnittwinkel der Schneidedrähte 3 nicht zu steil wird und nur vergleichsweise kleine Kräfte in horizontaler Richtung ausgeübt werden.It can also be seen that the wire holders 5, 10 are arranged in such a way that the cutting angle of the cutting wires 3 does not become too steep when cutting large-sized strand pieces and only comparatively small forces are exerted in the horizontal direction.
