Abstract
Description
Die Erfindung betrifft einen Spänebrecher zum Zerkleinern von Spänen nach dem Oberbegriff des Anspruchs 1.The invention relates to a chip crusher for crushing chips according to the preamble of
Aus
An der Seitenwand des Gehäuses sind Winkel angebracht, an denen jeweils zu einem Messersatz zugeordnete Widerlager befestigt sind. Ferner sind die Messerwellen und die zugeordneten Widerlager in Förderrichtung hintereinander geschaltet. Das in das Schneidwerk eingefüllte Schnittgut wird durch die Rotation des ersten Messersatzes zum ersten Widerlager befördert, dort geschnitten, fällt dann auf den rotierenden zweiten Messersatz und wird am zweiten Widerlager erneut geschnitten. Nachteilig ist die Gefahr des Durchfallens der Späne. Dichte Spänebüschel können ferner zu Blockaden des Spänebrechers führen. Die Störanfälligkeit und die Standzeiten sind deshalb noch nicht geeignet, den verschiedenen Anforderungen der Anwender zu genügen.On the side wall of the housing angles are attached to each of which are assigned to a set of knives abutment. Furthermore, the blade shafts and the associated abutment are connected in series in the conveying direction. The clippings filled in the cutting unit are conveyed to the first abutment by the rotation of the first set of knives, cut there, then fall onto the rotating second set of knives and are cut again on the second abutment. The disadvantage is the risk of the chips falling through. Dense tufts of chips can also lead to blockages of the chip breaker. The susceptibility to failure and the service life are therefore not yet suitable to meet the various requirements of the user.
Bekannt sind ferner Einwellenspänebrecher oder Zweiwellenspänebrecher, die dazu dienen die Späne zu zerkleinern. Bei einem Einwellenbrecher, wie er beispielsweise aus
Aufgabe der Erfindung ist es daher, einen Spänebrecher zu schaffen, der eine verbesserte Durchsatzleistung besitzt und dabei wartungsarm ist.The object of the invention is therefore to provide a chip breaker, which has an improved throughput while maintaining low maintenance.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Hierdurch wird ein Spänebrecher geschaffen, der mindestens zwei umlaufende Messerwellen aufweist, die unabhängig voneinander arbeiten gegenüber einem Mittelgegenmesser, das als ein Standmesser zwischen jeweils zwei Messerwellen angeordnet ist. Jede der mindestens zwei umlaufenden Messerwellen besitzt dabei einen eigenen Antrieb.As a result, a chip crusher is provided which has at least two rotating knife shafts, which operate independently of each other with respect to a center counter knife, which is arranged as a knife between each two knife shafts. Each of the at least two rotating knife shafts has its own drive.
Die mindestens zwei Messerwellen können folglich gleichdrehend oder gegendrehend und dabei rechtsdrehend und/oder linksdrehend angetrieben werden. Auch kann nur eine von beiden Messerwellen angetrieben werden. Diese Vielfalt von Rotationsbewegungen zweier durch ein Mittelgegenmesser kombinierter Messerwellen ermöglicht, Spänebüschel auseinanderzuziehen und/oder in ihrer Dichtigkeit zu verändern, wodurch deren Schneiden bzw. Brechen verbessert wird. Ferner werden Aufwalzungen vermieden. Bei Ausfall/Beschädigung einer Messerwelle durch z. B. Kernteile kann der Spänebrecher in einem Notbetrieb mit der/den verbleibenden Messerwellen weiterarbeiten und so Produktionsausfälle verhindern bzw. reduzieren. Bei einer Blockade einer Messerwelle kann die mindestens eine andere Messerwelle weiterarbeiten. Bei Aufgabe größerer Mengen kürzerer Späne werden diese bei Drehrichtung beider Messerwellen nach außen auf beide Messerwellen verteilt und Blockaden dadurch vermieden bzw. reduziert. Vorteilhaft ist schließlich, dass die Messerwellen gleich ausbildbar sind, wodurch die Ersatzteilhaltung vereinfacht ist.Consequently, the at least two cutter shafts can be driven in the same direction or counter-rotating while rotating clockwise and / or counterclockwise. Also, only one of both knife shafts can be driven. This multiplicity of rotational movements of two knife shafts combined by a central counter knife makes it possible to pull apart tufts of tufts and / or to change their tightness, thereby improving their cutting or breaking. Furthermore, Aufwalzungen be avoided. In case of failure / damage a knife shaft by z. B. core parts of the chip crusher in an emergency operation with the / the remaining blade shafts continue to work and prevent production losses or reduce. In the event of a blockage of a knife shaft, the at least one other knife shaft can continue to work. When larger quantities of shorter chips are used, they are distributed outwards on both blade shafts in the direction of rotation of both cutter shafts, thereby avoiding or reducing blockages. Finally, it is advantageous that the cutter shafts can be formed the same, which makes it easier to stock spare parts.
Vorzugsweise umfasst das Mittelgegenmesser einzelne Messerleisten, die als Einstellbauteile gegenüber der jeweiligen Messerwelle positionierbar sind. Eine optimale Schneidleistung ist dadurch gegeben.Preferably, the center counter knife comprises individual male blades, which can be positioned as adjusting components relative to the respective blade shaft. Optimal cutting performance is given.
Das Mittelgegenmesser ist vorzugsweise auf einem Messerhalter angeordnet, der gleichzeitig zur Versteifung des Brechergehäuses dient. Dies verbessert die Lagerung der Messerwellen am Brechergehäuse, insbesondere dann, wenn die Messerwellen parallel und quer zur Aufgaberichtung angeordnet sind.The center counter knife is preferably arranged on a knife holder, which also serves to stiffen the crusher housing. This improves the storage of the blade shafts on the crusher housing, in particular when the blade shafts are arranged parallel and transversely to the task direction.
Das Mittelgegenmesser kann einstückige oder geteilte Messerleisten umfassen, wobei über eine Breite des Mittelgegenmessers eine Abstandsweite zwischen den Außenumfängen der Messerwellen einstellbar ist. Über die Abstandsweite kann ein Aufgabefach für die Späne zwischen den Messerwellen eingestellt werden, in das Spänebüschel eintreten können für einen beidseitigen Angriff durch die umlaufenden Messerwellen.The center counter knife may comprise one-piece or split male connectors, wherein over a width of the center counter knife, a distance between the outer peripheries of the knife shafts is adjustable. About the distance can be a task tray for the chips between the knife shafts are set, can enter the tufts for a double-sided attack by the rotating cutter shafts.
Vorzugsweise sind zweite Standmesser vorgesehen, so dass eine Messerwelle zweiseitig gegen Standmesser arbeitet. Vorzugsweise sind die Standmesser fluchtend zu einer Ebene ausgerichtet, in denen die Drehachsen der Messerwellen liegen. Es wird dann vorzugsweise eine Messerebene mit inneren und äußeren Standmessern zu parallel angeordneten Messerwellen quer, schräg oder senkrecht zur Aufgaberichtung gebildet. Preferably, second countersink are provided, so that a knife shaft works on two sides against counter blade. Preferably, the stand knives are aligned with a plane in which the axes of rotation of the knife shafts lie. It is then preferably a knife plane with inner and outer knives to parallel knife shafts formed transversely, obliquely or perpendicular to the Aufgaberichtung.

Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to the embodiment shown in the accompanying drawings.
