Description

Die Erfindung betrifft einen Fräskopf einer Faserballenfräse mit einer Fräswalze, einem Rost, durch den Zähne der Fräswalze hindurchgreifen, sowie einer parallel zur Fräswalze und gleichsinnig mit ihr umlaufenden und in Fräsfahrrichtung gesehen hinter ihr liegende Kämmwalze zum Auskämmen von Fasern aus der Fräswalze.The invention relates to a milling head of a fiber bale milling machine with a milling drum, a grate through which the teeth of the milling drum reach, and a combing roller which runs parallel to and in the same direction with it and in the milling travel direction behind it, for combing fibers out of the milling drum.

Ein Fräskopf mit den gattungsgemäßen Merkmalen ist aus einem Prospekt B 12 666104401 7/82 der Firma Marzoli bekannt. Dieser besitzt eine zur Fräswalze parallele Kämmwalze. Beide Walzen laufen im gleichen Sinne um, und die Fräswalze zupft Fasermaterial aus dem Ballen und fördert dies einer Absaughaube zu, wobei der Rost zwischen den beiden Walzen und dem Faserballen liegt. Die Übertragungswalzen fördern dabei alle Fasern in die Absaugrinne, unabhängig davon, ob sie genügend aufgelöst, d.h. kurz genug sind.A milling head with the generic features is known from a brochure B 12 666104401 7/82 from Marzoli. This has a combing roller parallel to the milling drum. Both rollers rotate in the same sense, and the milling roller plucks fiber material from the bale and conveys this to a suction hood, the grate lying between the two rollers and the fiber bale. The transfer rollers convey all fibers into the Suction channel, regardless of whether it is sufficiently dissolved, ie short enough.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Fräskopf so auszubilden, daß durch ihn nur Fasern sowie Verbände zusammenhängender Fasern, die eine gewisse Länge von beispielsweise 80 mm nicht überschreiten, weiterbefördert werden.The object of the invention is to design a generic milling head so that only fibers and associations of connected fibers that do not exceed a certain length of 80 mm, for example, are conveyed through it.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der in der Fräsebene liegende Teil des Rostes zwischen den Walzen und vor dem Bereich endet, in den die Kämmwalze die von ihr aus der Fräswalze ausgekämmten Fasern hinunter auf die Fräsebene fördert.This object is achieved according to the invention in that the part of the grate lying in the milling plane ends between the rollers and in front of the area in which the combing roller conveys the fibers combed out of the milling roller down to the milling plane.

Vorzugsweise ist der Rost vor dem genannten Bereich zwischen der Fräswalze und der Kämmwalze nach oben über die Fräsebene hinaus verlängert. Ferner wird es bevorzugt, daß der Rost oberhalb der Kämmwalze parallel zur Fräsebene bis zur Wand des Fräskopfes verlängert ist.The grate in front of the area mentioned between the milling drum and the combing roller is preferably extended upward beyond the milling plane. It is also preferred that the grate above the combing roller is extended parallel to the milling plane up to the wall of the milling head.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Ein Fräskopf 2, der durch ein Fräsmaschinengestell 3 entlang einer Reihe von Faserballen 4 geführt werden kann, enthält eine um eine Achse 5a antreibbare Fräswalze 5 sowie einen Rost 1, der an eine Stelle 1a seines einen Endes am Fräskopf 2 befestigt ist und mit einem Teil 1c am Faserballen 4 so anliegt, daß die Zähne der Fräswalze 5 zwischen den einander parallelen Stäben des Rosts 1 Fasern aus dem Ballen 4 herauszupfen können, die dann von diesen Zähnen zu einer Absaughaube B geworfen werden. Der Fräskopf 2 weist ferner eine Kämmwalze 7 auf, die um ihre zur Achse 5a der Fräswalze 5 parallele Achse 7a in gleicher Drehrichtung antreibbar ist und einen solchen Abstand von den Faserballen 4 hat, daß ihre Zähne nicht in sie eingreifen. Die Walzen 5 und 7 liegen einander so nahe, daß die Zähne der Kämmwalze 7 die Fräswalze 5 von darauf noch verbliebenen Fasern befreien können; vorzugsweise liegen sie derart, daß die Umfangskreise der Zähne beider Walzen 5 und 7 einander berühren oder einander etwas überschneiden. Der Rost 1 ist über die Stelle hinaus, an der er an den Ballen 4 anliegt, derart verlängert, daß er zwischen den Achsen 5a und 7a der Walzen 5 und 7 hindurch und anschließend auf der den Ballen 4 gegenüberliegenden Seite der Kämmwalze 7 verläuft und an seinem Ende bei 1b am Fräskopf 2 befestigt ist.A milling head 2, which can be guided through a milling machine frame 3 along a row of fiber bales 4, contains a milling drum 5 which can be driven about an axis 5a and a grate 1 which is fastened to a milling head 2 at a position 1a at one end thereof and with one part 1c rests on the fiber bale 4 in such a way that the teeth of the milling drum 5 can pluck fibers out of the bale 4 between the parallel bars of the grate 1, which fibers are then thrown by these teeth to a suction hood B. The milling head 2 also has a combing roller 7 which can be driven in the same direction of rotation about its axis 7a parallel to the axis 5a of the milling roller 5 and has such a distance from the fiber bales 4 that its teeth do not engage in it. The rollers 5 and 7 are so close to one another that the teeth of the combing roller 7 can free the milling roller 5 from any fibers still remaining thereon; they are preferably such that the circumferential circles of the teeth of both rollers 5 and 7 touch or slightly overlap each other. The grate 1 is extended beyond the point at which it rests on the bales 4 in such a way that it passes between the axes 5a and 7a of the rollers 5 and 7 and then on the side opposite the bale 4 the combing roller 7 runs and is attached at its end at 1b to the milling head 2.

Beim Umlaufen der Fräswalze 5 zupfen ihre Zähne einzelne Fasern sowie zu Faserverbänden zusammenhängende Fasern aus dem Faserballen 4 und werfen die einzelnen Fasern und die leichten und kürzeren Faserverbände zur Absaughaube 6. Längere und schwerere Faserverbände werden durch die Kämmwalze 7 von der Fräswalze abgenommen und auf die Oberfläche der Ballen 4 geworfen Bei einem nachfolgenden Abzupfen dieser Faserballenstelle werden solche Verbände in der Regel durch die Fräswalze 5 aufgelöst.When the milling drum 5 rotates, its teeth pluck individual fibers as well as fibers connected to fiber associations from the fiber bale 4 and throw the individual fibers and the light and shorter fiber associations to the suction hood 6. Longer and heavier fiber associations are removed by the combing roller 7 from the milling roller and onto the Thrown surface of the bales 4 When this fiber bale site is subsequently plucked off, such dressings are generally broken up by the milling drum 5.
