Abstract

In order to be able to position the cutter blades (A, B, C) of a cutter head so that they are radially adjustable in a simple manner in the smallest possible axial space, toothing, (10) is formed in an elongated hole (7) in the area of the blade root (6) at its parallel opposite internal longitudinal edges, whereby toothing (11) at parallel opposite external longitudinal edges of a shaft mounting plate (8) engages with this toothing (10), the shaft mounting plate having a central opening (9), the shape of which corresponds to the cross section of a driven shaft (9'). In this arrangement the thickness of the shaft mounting plate (8) is not greater than the depth of the elongated hole (7), although the length of the shaft mounting plate (8) is smaller than the longitudinal extension of the elongated hole (7).

Description

Die Erfindung betrifft einen Messerkopf für Kutter mit wenigstens zwei im Massenausgleich bezüglich seiner Drehachse angeordneten Kuttermessern, von denen jedes ein fußseitiges Langloch und wenigstens einen Schneidenabschnitt aufweist, mit einer Wellenaufnahmescheibe mit einer zentralen Öffnung in Form eines regelmäßigen Vielecks, und mit einer an gegenüberliegenden parallelen Längsrändern der Wellenaufnahmescheibe ausgebildeten Verzahnung, der für den Eingriff eine Verzahnung an gegenüberliegenden parallelen Längsrändern des Kuttermessers zugeordnet ist.The invention relates to a cutter head for cutters with at least two cutter knives arranged in mass balance with respect to its axis of rotation, each of which has an elongated hole on the foot side and at least one cutting section, with a shaft receiving disk with a central opening in the form of a regular polygon, and with one on opposite parallel longitudinal edges the shaft receiving disc formed toothing, which is assigned a toothing on opposite parallel longitudinal edges of the cutter knife for the engagement.

Bei dem solchen, aus der DE-C-2 027 429 bekannten Messerkopf haben die Wellenaufnahmescheiben eine Längsaussparung mit gegenüberliegenden parallelen Innenrändern, die mit einer Verzahnung versehen sind. In dieser Längsaussparung ist der Fuß des jeweiligen Kuttermessers einsetzbar, das an seinen gegenüberliegenden parallelen äußeren Längsrändern mit einer entsprechenden Verzahnung versehen ist. Durch diese Verzahnung läßt sich zwar eine radiale Messerverstellung erreichen, jedoch ist die axiale Länge des Messerkopfes sehr groß, da zwischen zwei axial benachbarten Kuttermessern die Wellenaufnahmescheibe mit ihrer halben Dicke vorhanden ist. Wenn für einen bestimmten Kutter nun ein Messerkopf gebraucht werden kann, dessen axiale Gesamtlänge die Positionierung solcher Wellenaufnahmescheiben zwischen den Kuttermessern nicht mehr zuläßt, muß die durch die Verzahnung mögliche radiale Einstellung und sichere Halterung aufgegeben und eine komplizierte Verspannung mit Spannschrauben und Muttern verwendet werden.In such a cutter head known from DE-C-2 027 429, the shaft receiving disks have a longitudinal recess with opposite parallel inner edges which are provided with a toothing. The foot of the respective cutter knife can be used in this longitudinal recess, which is provided with a corresponding toothing on its opposite parallel outer longitudinal edges. This toothing makes it possible to achieve a radial knife adjustment, but the axial length of the knife head is very large, since the shaft receiving disk with half its thickness is present between two axially adjacent cutter knives. If a cutter head can now be used for a particular cutter whose overall axial length no longer allows the positioning of such shaft mounting disks between the cutter blades, the radial adjustment and secure mounting possible through the toothing must be given up and a complicated bracing with tensioning screws and nuts used.

Die der Erfindung zugrundeliegende Aufgabe besteht nun darin, den Messerkopf der gattungsgemäßen Art so auszubilden, daß eine formschlüssige radial verstellbare Positionierung und sichere Halterung der Kuttermesser des Messerkopfes auch dann gewährleistet ist, wenn die Kuttermesser axial direkt aneinander angeordnet werden.The object on which the invention is based is to design the cutter head of the generic type in such a way that a form-fitting, radially adjustable positioning and secure holding of the cutter knife of the cutter head is ensured even if the cutter knives are arranged axially directly against one another.

Diese Aufgabe wird bei dem Messerkopf der gattungsgemäßen Art dadurch gelöst, daß die Verzahnung der Wellenaufnahmescheibe an deren äußeren Längsrändern und die Verzahnung am Kuttermesser an den Längsrändern seines Langlochs ausgebildet ist, daß die Dicke der Wellenaufnahmescheibe nicht größer ist als die Tiefe des Langlochs in dem Kuttermesser, und daß die äußeren Längsränder der Wellenaufnahmescheibe kürzer sind als die Längsränder des Langlochs.This object is achieved in the cutter head of the generic type in that the toothing of the shaft receiving disc is formed on its outer longitudinal edges and the toothing on the cutter knife on the longitudinal edges of its elongated hole, that the thickness of the shaft receiving disc is not greater than the depth of the elongated hole in the cutter knife , and that the outer longitudinal edges of the shaft receiving disc are shorter than the longitudinal edges of the elongated hole.

Aus der DE-C-738 472 ist es zwar bekannt, bei einem Kuttermesser mit einer rechteckigen Aussparung im Messerfuß für das Einschieben einer quadratischen Treibwelle am offenen Ende der Aussparung an den Innenrändern eine Verzahnung vorzusehen, in die eine gleich starke Füllplatte mit ihrer Außenverzahnung eingreift, um dadurch eine Verstell- und Sicherungsmöglichkeit zu gewährleisten. Es handelt sich dabei jedoch lediglich um ein Verschlußteil an der Aussparung, um das Eindringen von im Kutter zerkleinerten Material in schwer zu reinigende Bereiche zu verhindern, da davon auszugehen ist, daß bei stärkeren Belastungen am Messerfuß sich die Enden der Aussparung aufbiegen, so daß die Haltewirkung der Welle durch die Füllplatte in Frage gestellt ist.From DE-C-738 472 it is known to provide a toothing in a cutter knife with a rectangular recess in the knife base for inserting a square drive shaft at the open end of the recess on the inner edges, in which an equally strong filler plate engages with its outer toothing in order to ensure adjustment and securing options. However, it is only a closure part on the recess to prevent the penetration of material shredded in the cutter into areas that are difficult to clean, since it can be assumed that the ends of the recess bend open under heavy loads on the knife base, so that the Holding effect of the shaft through the filler plate is questioned.

Bei dem erfindungsgemäßen Messerkopf lassen sich die Kuttermesser unter Berücksichtigung des erforderlichen Massenausgleichs in radialer Richtung entsprechend der Verzahnungsteilung einstellen und bezüglich der Treibwelle fixieren, wobei zur Erzielung der minimalen axialen Baulänge die Kuttermesser aixal direkt aneinander anliegend angeordnet werden können, da die Wellenaufnahmescheibe in dem Langloch des zugeordneten Kuttermessers aufgenommen ist und in ihrer Dicke der Tiefe des Langlochs im wesentlichen entspricht.With the cutter head according to the invention, the cutter knives can be adjusted in the radial direction according to the tooth pitch and taken into account with respect to the required mass balance, and fixed with respect to the drive shaft, whereby to achieve the minimum axial length, the cutter knives can be arranged aixally directly against one another, since the shaft receiving disc in the slot of the assigned cutter knife is recorded and corresponds in its thickness to the depth of the elongated hole substantially.

Da die Fixierung der Kuttermesser auf der Treibwelle durch die entsprechend gestaltete Öffnung in der Wellenaufnahmescheibe gewährleistet ist, können die Kuttermesser fußseitig größer ausgebildet werden, wodurch eine größere Spannfläche und dadurch eine stabilere Halterung auf der Treibwelle erreichbar sind. Außerdem wird durch den großen Querschnitt bei dem Übergang in den Schneidabschnitt die Messerbruchgefahr verringert. Schließlich können die Wellenaufnahmescheiben quadratisch ausgebildet werden, so daß auch an den Querrändern Verzahnungen mit anderer Teilung angebracht werden können, was eine radiale Zustellung von beispielsweise 3 mm, 1,5 mm und 0,75 mm ermöglicht.Since the cutter knives are fixed on the drive shaft through the appropriately designed opening in the shaft receiving disk, the cutter knives can be made larger on the foot side, as a result of which a larger clamping surface and thus a more stable mounting on the drive shaft can be achieved. In addition, the risk of knife breakage is reduced due to the large cross section during the transition to the cutting section. Finally, the shaft receiving discs can be square, so that toothings with a different pitch can also be attached to the transverse edges, which enables a radial infeed of, for example, 3 mm, 1.5 mm and 0.75 mm.

Anhand von Zeichnungen wird ein Auführungsbeispiel der Erfindung näher erläutert. Es zeigt:

  • Fig. 1 eine Draufsicht auf einen Messerkopf mit drei Kuttermessern und geschnittener Treibwelle,
  • Fig. 2 eine Seitenansicht des Messerkopfes von Fig. 1 und
  • Fig. 3 eine Draufsicht auf das vorderste Kuttermesser des Messerkopfes von Fig. 1.
An exemplary embodiment of the invention is explained in more detail with reference to drawings. It shows:
  • 1 is a plan view of a cutter head with three cutter knives and a cut drive shaft,
  • Fig. 2 is a side view of the cutter head of Fig. 1 and
  • 3 shows a plan view of the foremost cutter knife of the cutter head from FIG. 1.

Der in Fig. 1 und 2 gezeigte Messerkopf besteht aus drei Kuttermessern A, B und C, die in einer Winkelstellung von jeweils 120° zueinander auf einer Treibwelle 9' axial direkt aneinanderliegend angeordnet und am Wellenkopf 13 durch eine Sicherungsmutter 12 gesichert sind.The cutter head shown in FIGS. 1 and 2 consists of three cutter knives A, B and C, which are arranged in an angular position of 120 ° to each other on a drive shaft 9 'axially directly against each other and are secured on the shaft head 13 by a lock nut 12.

Das in Fig. 3 im einzelnen gezeigte Kuttermesser 1 entspricht in seiner Ausgestaltung dem Kuttermesser A, B oder C von Fig. 1. Das Kuttermesser 1 hat Schneidenabschnitte 2, 3, 4 und 5. Im Bereich des Messerfusses 6 ist ein Langloch 7 mit gegenüberliegenden parallelen inneren Längsrändern ausgebildet, die mit einer Innenverzahnung 10 versehen sind.The cutter knife 1 shown in detail in FIG. 3 corresponds in its design to the cutter knife A, B or C of FIG. 1. The cutter knife 1 has cutting sections 2, 3, 4 and 5. In the area of the knife foot 6 there is an elongated hole 7 with opposing ones parallel inner longitudinal edges formed, which are provided with an internal toothing 10.

Eine Wellenaufnahmescheibe 8 mit einer zentralen sechseckigen Öffnung 9 für die Aufnahme einer Triebwelle 9' mit entsprechendem Sechskantprofil weist an ihren gegenüberliegenden parallelen äußeren Längsrändern eine Außenverzahnung 11 auf, die für den Eingriff mit der Verzahnung 10 an den Längsrändern des Langlochs 7 ausgebildet ist, wodurch eine radiale Einsetllung des Kuttermessers 1 bezüglich der zentralen Öffnung 9 der Wellenaufnahmescheibe 8 und somit bezüglich der Treibwelle 9' um die vorgesehene Zahnteilung möglich ist.A shaft receiving disc 8 with a central hexagonal opening 9 for receiving a drive shaft 9 'with a corresponding hexagonal profile has on its opposite parallel outer longitudinal edges an external toothing 11, which for engagement with the Toothing 10 is formed on the longitudinal edges of the elongated hole 7, whereby a radial insertion of the cutter knife 1 with respect to the central opening 9 of the shaft receiving disk 8 and thus with respect to the drive shaft 9 'around the intended tooth pitch is possible.

Die Längserstreckung de Wellenaufnahmescheibe 8 ist geringer als die Ausdehnung des Langlochs 7 in seiner Längsrichtung, um die radiale Nachstellung über einen bestimmten Längsbereich zu gewährleisten, die durch Nachschleifen und ausgewuchtetes Positionieren der Kuttermesser erforderlich wird.The longitudinal extent of the shaft receiving disc 8 is less than the extent of the elongated hole 7 in its longitudinal direction in order to ensure the radial adjustment over a certain longitudinal range, which is required by regrinding and balanced positioning of the cutter knife.

Die Dicke der Wellenaufnahmescheibe 8 entspricht im wesentlichen der Dicke des Kuttermessers 1 im Bereich seines Messerfusses 6, also der Tiefe des Langlochs 7, so daß, wenn die Wellenaufnahmescheibe 8 in dem jeweiligen Kuttermesser 1 bzw. A, B und C angeordnet ist, der Messerkopf aus kompakt aneinanderliegenden Bauelementen besteht.The thickness of the shaft receiving disk 8 corresponds essentially to the thickness of the cutter knife 1 in the area of its knife base 6, that is to say the depth of the elongated hole 7, so that when the shaft receiving disk 8 is arranged in the respective cutter knife 1 or A, B and C, the cutter head consists of compact components lying next to each other.
