Abstract

A staple fiber cutting machine has a cutter supporting member which supports a plurality of cutters and is driven in rotation by a drive, a gap formed so that a cable can be introduced into the gap, and a pressing member which is driven in rotation during idle running of the machine, prior to introduction of a cable into the gap. The machine works so that not only the cutter supporting member rotates, but also the pressing member rotates during the starting phase or the idle running of the machine.

Description

Die vorliegende Erfindung betrifft eine Stapelfaserschneidmaschine gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a staple fiber cutting machine according to the preamble of claim 1.

Bei den in den Fig. 1 und 2 der Hauptanmeldung dargestellten Ausführungsbeispielen wird der Messerträger durch einen Motor angetrieben. Das Andrückorgan hat keinen eigenen Antrieb, sondern wird durch Haftreibung mitgenommen, indem es sich auf dem Wickel abwälzt, der sich in stationärem Betrieb auf dem Wickelkern befindet. Auf diese Weise paßt sich seine Umdrehungsgeschwindigkeit selbsttätig der Umdrehungsgeschwindigkeit des Messerträgers an, so daß zwischen dem Kabel und dem Andrückorgan keine gleitende Bewegung besteht. Dadurch ist die Gleitreibung im stationären Betrieb völlig ausgeschaltet.In the embodiments shown in FIGS. 1 and 2 of the main application, the knife carrier is driven by a motor. The pressure element does not have its own drive, but is entrained by static friction as it rolls on the winding, which is in stationary operation on the winding core. In this way, its rotational speed adjusts itself automatically to the rotational speed of the knife carrier, so that there is no sliding movement between the cable and the pressing member. This eliminates sliding friction in stationary operation.

Das Letztere gilt aber nicht für die Phase des Anfahrens. Beim Anfahren der Maschine wird zunächst der Messerträger auf hohe Drehzahl gebracht. Da zunächst noch kein Wickel vorhanden ist, bleibt das Andrückorgan in Ruhe. Erst nach Einlegen des Kabels beginnt der sich aufbauende Wickel, das Andrückorgan aus der Ruhe auf die Betriebsgeschwindigkeit zu beschleunigen. Dabei tritt ähnlich wie bei einer Reibungskupplung kurzzeitig eine starke Gleitreibung auf. Bei hohen Geschwindigkeiten kann die Wärmeentwicklung so groß sein, daß das Fasermaterial erweicht und zusammenbackt. Dadurch kann das Anfahren erschwert oder sogar unmöglich gemacht werden.The latter does not apply to the start-up phase. When starting the machine, the knife carrier is first brought up to high speed. Since there is initially no winding, the pressure element remains at rest. The building up only begins after the cable has been inserted Wrap to accelerate the pressure element from rest to operating speed. Similar to a friction clutch, strong sliding friction occurs briefly. At high speeds, the heat can be so great that the fiber material softens and cakes. This can make starting difficult or even impossible.

Dieses Problem besteht grundsätzlich auch bei herkömmlichen Stapelfaserschneidmaschinen, z.B. gemäß US-PS 4,014,231. Es tritt aber bei der Maschine gemäß der Hauptanmeldung in besonders starkem Maße hervor, da bei dieser Maschine der Winkelbereich, in dem das Andrückorgan mit dem Wickel in Berührung steht, gegenüber vorbekannten Maschinen in an sich wünschenswerter Weise vervielfacht ist. Daher ist die Einwirkzeit der Reibung größer und die Kühlung durch die Umgebungsluft geringer als bei den herkömmlichen Maschinen.This problem basically also exists with conventional staple fiber cutting machines, e.g. according to U.S. Patent 4,014,231. However, it is particularly apparent in the machine according to the main application, since in this machine the angular range in which the pressing member is in contact with the winding is multiplied in a desirable manner in comparison with previously known machines. As a result, the exposure time to friction is longer and cooling by the ambient air is less than with conventional machines.

Der Erfindung liegt die Aufgabe zugrunde, eine Stapelfaserschneidmaschine gemäß dem Oberbegriff des Anspruchs 1 weiter auszubilden, so daß beim Anfahren zwischen Wickel und Andrückorgan keine Gleitreibung auftritt.The invention has for its object to further develop a staple fiber cutting machine according to the preamble of claim 1, so that no sliding friction occurs when starting between the winding and pressing member.

Diese Aufgabe wird erfindungsgemäß durch das kennzeichnende Merkmal des Anspruchs 1 gelöst.This object is achieved by the characterizing feature of claim 1.

Das Andrückorgan kann also in Umdrehung versetzt werden, ohne daß ein Wickel vorhanden ist. Indem man es vor Ein-. legen des Kabels auf die gleiche Drehzahl bringt wie den Messerträger, vermeidet man beim Anfahren jegliche Gleitreibung.The pressing member can thus be rotated without a winding being present. By doing it before entering. placing the cable at the same speed as the knife carrier, you avoid any sliding friction when starting.

Die Erfindung ist in Kombination mit der Erfindung gemäß der Hauptanmeldung besonders wichtig und vorteilhaft. Sie kann aber auch bei anderen Stapelfaserschneidmaschinen nützlich sein. Daher wird für die Erfindung auch selbständiger Schutz beansprucht.The invention is particularly important and advantageous in combination with the invention according to the main application. However, it can also be useful in other staple fiber cutting machines. Therefore, independent protection is also claimed for the invention.

Für die technische Realisierung der Erfindung stehen dem Fachmann ohne weiteres zahlreiche Möglichkeiten zur Verfügung. Einige Beispiele sind in den Unteransprüchen angegeben.Numerous possibilities are readily available to the person skilled in the art for the technical implementation of the invention. Some examples are given in the subclaims.

Zur Veranschaulichung der Erfindung dient die Zeichnung, in der der Einfachheit halber zwei Ausführungsbeispiele vereint sind.The drawing serves to illustrate the invention, in which two exemplary embodiments are combined for the sake of simplicity.

An einem nur teilweise angedeuteten feststehenden Maschinengestell 1 ist mit einem Gelenkzapfen 2 und einer öse 3 eine Platte 4 befestigt, die aus der dargestellten horizontalen Betriebsstellung in Richtung des Pfeiles 5 um etwa 90° oder mehr verschwenkbar ist. In einer Öffnung der Platte 4 sitzt das zylindrische Lagergehäuse 7, dessen kragenartiger Ansatz durch Schrauben 8 mit der Platte 4 fest verbunden ist. In dem Lagergehäuse 7 ist mit Lagern 9, 10 eine Welle 11 gelagert, die durch einen am oberen Ende des Lagergehäuses 7 angeflanschten Motor 12 antreibbar ist. Auf dem nach unten weisenden Ende der Welle 11 sitzt der Messerträger 13, aus dem die Messer 14 radial nach außen vorstehen. Ihre Schneiden sind nach oben gerichtet. Die Mantelfläche des Messerträgers 13 ist oberhalb der von den Messerschneiden aufgespannten Ebene als Kugelzone ausgebildet. Der Mittelpunkt 15 der zugehörigen Kugel stimmt mit dem Mittelpunkt der oberen Stirnfläche des Messerträgers 13 überein.A plate 4 is fastened to a fixed machine frame 1, which is only partially indicated, with a pivot pin 2 and an eyelet 3, which plate can be pivoted from the horizontal operating position shown in the direction of arrow 5 by approximately 90 ° or more. In an opening of the plate 4 sits the cylindrical bearing housing 7, the collar-like approach is firmly connected to the plate 4 by screws 8. In the bearing housing 7, a shaft 11 is supported with bearings 9, 10, which shaft can be driven by a motor 12 flanged to the upper end of the bearing housing 7. The knife carrier 13, from which the knives 14 protrude radially outward, sits on the downward-facing end of the shaft 11. Your cutting edges are directed upwards. The outer surface of the knife carrier 13 is formed as a spherical zone above the plane spanned by the knife edges. The center 15 of the associated ball coincides with the center of the upper end face of the knife carrier 13.

An dem Messerträger 13 ist mit mindestens einer Schraube 16 sowie mit Paßstiften 17 das Bauteil 18 befestigt. Dieses besteht aus einer ringförmigen Nabe 19, einer dazu koaxialen Trommel 20 und drei in gleichmäßigen Winkelabständen von 120° angeordneten Speichen 21, die die Nabe 19 mit der Trommel 20 verbinden. Zwischen Nabe 19 und Messerträger 13 ist ein Ring 22 eingespannt, der mit z.B. zweiundsiebzig gleichmäßig auf dem Umfang verteilten radialen Schlitzen versehen ist. In den Schlitzen sitzen die inneren Enden der Messer 14. Ein Stützring 23 sichert die Messer 14 in ihrer radialen Lage. Auf der oberen Stirnfläche der Trommel 20 sitzt als Gegenstück zu dem Ring 22 in derselben Ebene ein Ring 24, der entsprechende radiale Schlitze zur Aufnahme der äußeren Messerenden aufweist. Der Ring 24 ist zwischen der Trommel 20 und einem weiteren Ring 25 eingespannt, der durch Schrauben 26 und Paßstifte 27 fest mit der Trommel 20 verbunden ist. Der Ring 25 übergreift nach Art eines überwurfringes die äußeren Messerenden. Die der kugeligen Mantelfläche des Messerträgers 13 zugewandte Innenfläche des Ringes 25 ist als konzentrische Hohlkugelzone ausgebildet. Dazwischen befindet sich ein Ringkanal 28.The component 18 is fastened to the knife carrier 13 with at least one screw 16 and with dowel pins 17. This consists of an annular hub 19, a drum 20 coaxial therewith and three spokes 21 arranged at uniform angular intervals of 120 °, which connect the hub 19 to the drum 20. Between the hub 19 and knife carrier 13, a ring 22 is clamped, the ver with even seventy-two on the circumference ver shared radial slots is provided. The inner ends of the knives 14 sit in the slots. A support ring 23 secures the knives 14 in their radial position. On the upper end face of the drum 20 sits as a counterpart to the ring 22 in the same plane, a ring 24 which has corresponding radial slots for receiving the outer knife ends. The ring 24 is clamped between the drum 20 and a further ring 25 which is firmly connected to the drum 20 by screws 26 and dowel pins 27. The ring 25 engages over the outer knife ends in the manner of a collar ring. The inner surface of the ring 25 facing the spherical outer surface of the knife carrier 13 is designed as a concentric hollow spherical zone. In between is an annular channel 28.

Ein Andrückring 29, der mittels schiefgestellter Lager 30 um eine zur geometrischen Achse der Welle 11 geneigte, diese im Kugelmittelpunkt 15 schneidende Achse 31 frei drehbar ist, taucht auf der in der Zeichnung rechts liegenden Seite mit geringem seitlichem Spiel in den Ringkanal 28 bis in die Nähe der Messerschneiden 1. Auf der linken Seite bleibt infolge der Schiefstellung ein Spalt für das tangential einlaufende Kabel offen. Zumindest in der Nähe der den Messern 14 zugekehrten Stirnfläche sind die Außenfläche und die Innenfläche des Andrückringes 29 den kugeligen seitlichen Begrenzungsflächen des Ringkanals 28 angepaßt. An der Platte 4 ist mit nicht dargestellten einfachen Mitteln ein Motor 32 befestigt. Seine geometrische Achse ist parallel zur Achse 31 des Andrückorgans 29. Auf der Welle des Motors sitzt ein Reibrad 33, das an der Umfangsfläche des Andrückorgans 29 und des Lagerringes 34, an dem das Andrückorgan befestigt ist, angreift. Der Motor 32 ist um eine die Zeichnungsebene durchdringende Achse in Richtung des Pfeiles 35 verschwenkbar und in der verschwenkten Stellung arretierbar. In dieser Stellung ist also das Andrückorgan 29 von dem Motor 32 abgekuppelt.A pressure ring 29, which can be freely rotated by means of a tilted bearing 30 about an axis 31 inclined to the geometric axis of the shaft 11, which intersects in the center 15 of the ball, plunges on the right side in the drawing with little lateral play into the annular channel 28 into Proximity of the knife edges 1. Due to the misalignment, a gap for the tangentially entering cable remains open on the left side. At least in the vicinity of the end surface facing the knives 14, the outer surface and the inner surface of the pressure ring 29 are adapted to the spherical lateral boundary surfaces of the ring channel 28. A motor 32 is fastened to the plate 4 by simple means, not shown. Its geometric axis is parallel to the axis 31 of the pressing member 29. On the shaft of the motor there is a friction wheel 33 which engages on the peripheral surface of the pressing member 29 and the bearing ring 34 to which the pressing member is attached. The motor 32 can be pivoted about an axis penetrating the plane of the drawing in the direction of the arrow 35 and can be locked in the pivoted position. In this position, the pressure member 29 is uncoupled from the motor 32.

Bevor die Maschine in Betrieb gesetzt wird, ist der Motor 32 mit dem Reibrad 33 in die in der Zeichnung dargestellte Stellung zu bringen. Der Motor 32 wird eingeschaltet, so daß bei ebenfalls eingeschaltetem Motor 12 das Andrückorgan 29 etwa mit der gleichen Drehzahl rotiert wie-der Messerträger 13. Die Relativgeschwindigkeit zwischen Andrückorgan 29 und Messerträger 13 ist daher in Umfangsrichtung praktisch Null. Legt man nun in den Ringkanal 28 ein Kabel ein, so wird das Kabel allseitig mit der gleichen Geschwindigkeit erfaßt. Die schädliche Gleitreibung zwischen dem Kabel und dem Andrückorgan 29 tritt nicht auf. Sobald sich die für den stationären Betrieb charakteristische Fadenmenge in dem Ringkanal 28 befindet, wird das Andrückorgan 29 durch die zwischen ihm und dem Wickel wirkende Haftreibung mitgenommen. Der Motor 32 mit dem Reibrad 33 kann gemäß Pfeil 35 verschwenkt und abgeschaltet werden.Before the machine is started, the motor 32 with the friction wheel 33 must be brought into the position shown in the drawing. The motor 32 is switched on, so that when the motor 12 is also switched on, the pressure element 29 rotates at approximately the same speed as the knife carrier 13. The relative speed between the pressure element 29 and knife carrier 13 is therefore practically zero in the circumferential direction. If a cable is now inserted into the ring channel 28, the cable is detected on all sides at the same speed. The harmful sliding friction between the cable and the pressure element 29 does not occur. As soon as the thread quantity characteristic of stationary operation is in the ring channel 28, the pressing member 29 is carried along by the static friction acting between it and the winding. The motor 32 with the friction wheel 33 can be pivoted and switched off according to arrow 35.

Ein anderes Ausführungsbeispiel der Erfindung ist der Einfachheit halber in derselben Zeichnung dargestellt, obwohl dabei natürlich in Wirklichkeit der Motor mit dem Reibrad entfällt. In der in der Zeichnung oben liegenden Stirnfläche des Messerträgers 13 sitzen in Umfangsnähe in gleichen Winkelabständen mehrere Magnete 36, die nur grob schematisch dargestellt sind. Ein Ring 37, der an der Unterseite des Lagerringes 34 fest geschraubt ist und auch zur Einkapslung der Lager 30 dient, ist mit entsprechenden Gegenstücken 38 aus ferromagnetischem Material bestückt. Es versteht sich, daß je nach Form und Anordnung der Magnete 36 und der Gegenstücke 38 der Messerträger 13 und/oder der Ring 37 ganz oder teilweise aus einem nicht ferromagnetischem Material bestehen.Another exemplary embodiment of the invention is shown in the same drawing for the sake of simplicity, although of course the motor with the friction wheel is in fact omitted. In the end face of the knife carrier 13 lying at the top in the drawing, a plurality of magnets 36 are seated in the vicinity of the circumference at equal angular intervals, which are shown only roughly schematically. A ring 37, which is screwed tightly to the underside of the bearing ring 34 and also serves to encapsulate the bearing 30, is equipped with corresponding counterparts 38 made of ferromagnetic material. It goes without saying that, depending on the shape and arrangement of the magnets 36 and the counterparts 38, the knife carrier 13 and / or the ring 37 consist entirely or partially of a non-ferromagnetic material.

Bei diesem Ausführungsbeispiel wird das Andrückorgan 29 durch die Wirkung der Magnete beim Anfahren mitgenommen und auf Drehzahl des Messerträgers 13 gebracht. Sobald der stationäre Betriebszustand erreicht ist, ist die Wirkung der Magnete ohne Bedeutung.In this exemplary embodiment, the pressure element 29 is taken along by the action of the magnets when moving off and brought to the speed of the knife carrier 13. As soon as the stationary operating state is reached, the effect of the magnets is irrelevant.
