Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Lagerung eines Messerkopfs einer Anlage zum Granulieren von Kunststoff mit einer Messerkopfwelle, mit einer drehfest mit der Messerkopfwelle verbindbaren Messerkopfaufnahme und mit einer elastomeren Ausgleichshülse zwischen der Messerkopfaufnahme und dem The invention relates to a device for mounting a cutter head of a plant for granulating plastic with a cutter head shaft, with a cutter head mount which can be connected in a rotationally fixed manner to the cutter head shaft and with an elastomeric compensation sleeve between the cutter head mount and the

Messerkopf. knife head.

In Anlagen zum Granulieren von Kunststoff wird die Kunststoffschmelze in eine Anzahl von Strängen aufgeteilt, die durch eine Lochplatte hindurch in ein Gehäuse austreten und mithilfe eines rotierenden Messerkopfs zu einem Granulat geschnitten werden, das in einem das Gehäuse durchströmenden Kühl- und Fördermedium erstarrt und mit dem Kühl- und Fördermedium aus dem Gehäuse ausgetragen wird. Um eine zur Lochplatte parallele Messerführung zu gewährleisten, muss eine allfällige Winkelfehlstellung der Messerkopfwelle gegenüber der Lochplatte ausgeglichen werden. Zu diesem Zweck ist es bekannt, zwischen dem Messerkopf und der Messerkopfwelle ein Kreuz- oder Kugelgelenk vorzusehen. Kreuz- und Kugelgelenke haben aber neben dem mit ihrem Einsatz verbundenen Konstruktionsaufwand insbesondere bei einer Unterwassergranulation den Nachteil, anfällig gegenüber Ablagerungen zu sein, die Einfluss auf die In systems for granulating plastic, the plastic melt is divided into a number of strands, which exit through a perforated plate into a housing and are cut into granules using a rotating cutter head Cooling and pumping medium is discharged from the housing. In order to ensure that the knife is guided parallel to the perforated plate, any incorrect angular position of the cutterhead shaft relative to the perforated plate must be compensated for. For this purpose it is known to provide a universal or ball joint between the cutter head and the cutter head shaft. However, in addition to the design effort associated with their use, universal and ball joints have the disadvantage, particularly in the case of underwater granulation, of being susceptible to deposits that influence the

Leichtgängigkeit dieser Gelenke haben. Ease of movement of these joints have.

Um diesen Nachteilen zu begegnen, wurde bereits vorgeschlagen, zwischen dem Messerkopf und der Messerkopfwelle eine Messerkopfaufnehme vorzusehen, die drehfest mit der Messerkopfwelle verbindbar ist und den Messerkopf unter Zwischenschaltung einer elastomeren, kreiszylindrischen Ausgleichshülse trägt. In order to counteract these disadvantages, it has already been proposed to provide a cutter head receptacle between the cutter head and the cutter head shaft, which can be connected in a rotationally fixed manner to the cutter head shaft and carries the cutter head with the interposition of an elastomeric, circular-cylindrical compensating sleeve.

sodass der Messerkopf im Rahmen der elastischen Verformbarkeit der so that the cutter head in the context of the elastic deformability

übertragen werden kann. can be transferred.

Der Erfindung liegt somit die Aufgabe zugrunde, eine konstruktiv einfache Lagerung des Messerkopfs vorzusehen, die einen Ausgleich von Winkelfehlern zwischen der Messerkopfwelle und der Lochplatte mithilfe einer elastomeren Ausgleichshülse erlaubt, ohne Schwierigkeiten in Bezug auf die Drehmomentübertragung von der The invention is therefore based on the object of providing a structurally simple mounting of the cutter head, which allows angular errors between the cutter head shaft and the perforated plate to be compensated for using an elastomeric compensation sleeve, without difficulties with regard to the torque transmission from the

Messerkopfwelle auf den Messerkopf befürchten zu müssen. Cutterhead shaft on the cutterhead.

Ausgehend von einer Vorrichtung der eingangs geschilderten Art löst die Erfindung die gestellte Aufgabe dadurch, dass die Ausgleichshülse einen von der Kreisform abweichenden Querschnitt mit einem Flächenschwerpunkt aufweist, der auf der Based on a device of the type described above, the invention solves the problem in that the compensating sleeve has a non-circular cross-section with a centroid on the

Drehachse der Messerkopfwelle liegt. axis of rotation of the cutter head shaft.

Zufolge dieser Maßnahmen kommt es für die Drehmomentübertragung von der Messerkopfaufnahme auf den Messerkopf über die elastomere Ausgleichshülse nicht auf die Haftvermittlung zwischen der Ausgleichshülse einerseits und der Messerkopfaufnahme bzw. dem Messerkopfträger anderseits an, weil aufgrund der von einer Kreisform abweichenden Querschnittsform der Ausgleichshülse der Messerkopf und die Messerkopfaufnahme auch ohne Ausgleichshülse nicht beliebig gegeneinander verdreht werden können. Eine Relativdrehung zwischen dem Messerkopf und der Messerkopfaufnahme ist somit lediglich im Rahmen der Verformbarkeit der Umfangswand der Ausgleichshülse zwischen den einander gegenüberliegenden Umfangsflächen der Messerkopfaufnahme und des Messerkopfs möglich, wodurch die Drehmomentübertragung jedoch nicht beeinträchtigt wird. Der auf der Drehachse der Messerkopfwelle liegende Flächenschwerpunkt des Querschnitts der Ausgleichshülse sichert in einfacher Art As a result of these measures, the transmission of torque from the cutter head mount to the cutter head via the elastomeric compensation sleeve does not depend on the bonding between the compensation sleeve on the one hand and the cutter head mount or the cutter head carrier on the other hand, because due to the cross-sectional shape of the compensation sleeve deviating from a circular shape, the cutter head and the cutter head mount cannot be twisted against each other at will, even without a compensating sleeve. A relative rotation between the cutter head and the cutter head mount is therefore only possible within the scope of the deformability of the peripheral wall of the compensating sleeve between the opposing peripheral surfaces of the cutter head mount and the cutter head, whereby the torque transmission is not impaired. The area center of gravity of the cross section of the compensating sleeve lying on the axis of rotation of the cutter head shaft secures in a simple way

einen entsprechenden Massenausgleich in Bezug auf die Drehachse. a corresponding mass balance in relation to the axis of rotation.

gegenüber der Messerkopfaufnahme gehalten wird. is held against the cutter head mount.

Obwohl im Querschnitt ovale Ausgleichshülsen den erfindungsgemäßen Vorgaben durchaus genügen, ergeben sich einfachere Fertigungsbedingungen, wenn der Querschnitt der Ausgleichshülse die Form eines Polygons aufweist, und zwar im Hinblick auf die geforderte Lage des Flächenschwerpunkts insbesondere die Form Although compensating sleeves with an oval cross-section meet the requirements of the invention, simpler manufacturing conditions result if the cross-section of the compensating sleeve is in the shape of a polygon, specifically with regard to the required position of the centroid, in particular the shape

eines zur Drehachse der Messerkopfwelle koaxialen regelmäßigen Polygons. a regular polygon coaxial to the axis of rotation of the cutterhead shaft.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es In the drawing, the subject of the invention is shown as an example. It

Fig. 2 einen Schnitt nach der Linie Il-II der Fig. 1. Fig. 2 shows a section along the line II-II of Fig. 1.

Wie in der Fig. 2 angedeutet ist, weist eine Anlage zum Granulieren von Kunststoff eine Lochplatte 1 auf, durch die Schmelzestränge mithilfe von Düsen 2 in ein Gehäuse austreten und durch Messer 3 eines rotierenden Messerkopfs 4 zu einem Granulat geschnitten werden, das in einem das Gehäuse durchströmenden Kühlund Fördermedium, beispielsweise Wasser, erstarrt und mit dem Kühl- und As indicated in Fig. 2, a plant for granulating plastic has a perforated plate 1 through which melt strands exit into a housing with the aid of nozzles 2 and are cut into granules by blades 3 of a rotating cutter head 4, which are then Cooling and conveying medium flowing through the housing, for example water, solidifies and is connected to the cooling and

Fördermedium aus dem Gehäuse ausgetragen wird. Pumped medium is discharged from the housing.

Die Messer 3 sind auf Messerträgern 5 angeordnet, die in Aufnahmebohrungen 6 des Messerkopfs 4 mithilfe von Passstiften 7 formschlüssig gehalten werden. Zum Antrieb des Messerkopfs 4 dient eine Messerkopfwelle 8, wobei die Forderung besteht, dass die Messer 3 entlang der Oberfläche der Lochplatte 1 und parallel dazu zu führen sind. Dies setzt eine zur Lochplatte 1 senkrechte Drehachse voraus, womit allerdings aufgrund der unvermeidbaren Toleranzen nicht gerechnet werden kann. Aus diesem Grund ist der Messerkopf 4 gegenüber der Messerkopfwelle 8 The cutters 3 are arranged on cutter carriers 5 which are held in a form-fitting manner in mounting bores 6 of the cutter head 4 using dowel pins 7 . A cutter head shaft 8 is used to drive the cutter head 4, with the requirement that the cutters 3 must be guided along the surface of the perforated plate 1 and parallel thereto. This requires an axis of rotation perpendicular to the perforated plate 1, which, however, cannot be expected due to the unavoidable tolerances. For this reason, cutter head 4 is opposite cutter head shaft 8

allseits begrenzt verschwenkbar zu lagern. to be stored in a limited way on all sides.

Zu diesem Zweck ist der Messerkopf 4 nicht unmittelbar auf der Messerkopfwelle 8 gelagert, sondern mithilfe einer Messerkopfaufnahme 9, zwischen der und dem Messerkopf 4 eine elastomere Ausgleichshülse 10 mit einem Querschnitt in Form eines regelmäßigen Polygons vorgesehen ist, wie dies insbesondere der Fig. 1 entnommen werden kann. Diese topfartig ausgebildete Ausgleichshülse 10 umschließt nicht nur den Mantel 11 der Messerkopfaufnahme 9, sondern deckt auch mit ihrem Boden 12 die Stimwand 13 der Messerkopfaufnahme 9 ab, die unter Zwischenlage der Ausgleichshülse 10 in eine Ausnehmung 14 des Messerkopfs 4 For this purpose, the cutter head 4 is not mounted directly on the cutter head shaft 8, but rather with the aid of a cutter head receptacle 9, between which and the cutter head 4 there is an elastomeric compensation sleeve 10 with a cross section in the form of a regular polygon, as can be seen in particular from Fig. 1 can be. This cup-shaped compensating sleeve 10 not only encloses the jacket 11 of the cutter head receptacle 9, but also covers the end wall 13 of the cutter head receptacle 9 with its bottom 12, which, with the compensating sleeve 10 interposed, fits into a recess 14 of the cutter head 4
