The invention is characterised in that a movement of at least one part of the needles (7) or saw-tooth punching parts (12) is superimposed on the opening, grading or combing movement, with at least one component moving perpendicular to said opening, grading or combing movement.

Description

Garnitur für eine Auflöse-, Sortier- oder Kämmeinrichtung an TextilmaschinenSet for a dissolving, sorting or combing device on textile machines
Die Erfindung richtet sich auf eine Garnitur für eine Auflöse-, Sortier- oder Kämmeinrichtung an Textilmaschinen, wie z.B. Rundkamm, Fixkamm, Karde, Spinneinrichtung oder dergleichen, mit einer Mehrzahl von Nadeln oder Sagezahnstanzteilen, die relativ zu einem Faserband eine Auflöse-, Sortieroder Kämmbewegung ausführen.The invention is directed to a set for a dissolving, sorting or combing device on textile machines, such as Round comb, fixed comb, card, spinning device or the like, with a plurality of needles or saw tooth punched parts, which perform a dissolving, sorting or combing movement relative to a sliver.
Derartige textile Auflöse-, Sortier- oder Kämmeinrichtungen dienen dazu, ein oll- oder Baumwollfaserband zu parallelisieren und darin vorhandene Verunreinigungen auszukämmen.Such textile dissolving, sorting or combing devices are used to parallelize a wool or cotton fiber tape and to comb out any contaminants present therein.
Die Qualität des Endprodukts wird sehr stark von der Qualität dieses Kämm- Vorganges beeinflußt, weshalb zahlreiche Ansätze existieren, das Kämmergebnis immer weiter zu verbessern.The quality of the end product is very much influenced by the quality of this combing process, which is why there are numerous approaches to continuously improve the combing result.
Zur Verbesserung der Parallelisierungseigenschaften wird insbesondere mit der Konfiguration der Nadeln und Sägezahnstanzteile als solcher und mit der Positionierung und Dimensionierung relativ zueinander gearbeitet.To improve the parallelization properties, work is carried out in particular with the configuration of the needles and sawtooth stampings as such and with the positioning and dimensioning relative to one another.
Ein weiteres Problem besteht darin, daß die Kämmeinrichtungen durch ausgekämmte Partikel, die sich in den Kämmeinrichtungen festsetzen, erheblich an Wirksamkeit verlieren. Für ein optimales Parallelisierungsergebnis wäre es wünschenswert, die Dichte der Nadeln bzw. Sägezahnstanzteile möglichst hoch zu machen, wodurch jedoch die Gefahr erheblich vergrößert wird, daß sich Partikel da festsetzen und den Wirkungsgrad der Kämmung reduzieren.Another problem is that the combing devices lose their effectiveness considerably due to combed-out particles which become lodged in the combing devices. For an optimal parallelization result, it would be desirable to make the density of the needles or sawtooth stamped parts as high as possible, but this increases the risk considerably that particles get stuck there and reduce the efficiency of the combing.
Es gibt deshalb auch zahlreiche Ansätze, festgesetzte Partikel aus Kämmein- richtungen wieder zu entfernen, wobei insoweit insbesondere mechanische Reinigungsmittel, wie Bürsten oder Putzklingen bekannt sind. Diese weisen allerdings den erheblichen Nachteil auf, daß aufgrund des mechanischen Kontaktes ein Verschleiß der Nadeln und der Sägezahnstanzteile bedingt ist. Eine erhebliche Verbesserung brachte deshalb die Einfuhrung einer pneumatischen Reinigung, insbesondere an Fixkämmen.There are therefore numerous approaches, stuck particles from comb to remove directions again, mechanical cleaning agents such as brushes or cleaning blades being known. However, these have the considerable disadvantage that wear of the needles and the sawtooth stamped parts is caused by the mechanical contact. The introduction of pneumatic cleaning, especially on fixed combs, therefore brought a significant improvement.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Kämmeinrichtung der eingangs genannten Art so auszugestalten, daß das Kämmergebnis weiter verbessert wird, d.h. einerseits ein sanfter Eingriff ermöglicht wird und andererseits eine gute Kämmwirkung, wobei ein Verbleiben der ausgekämmten Partikel in der Kämmeinrichtung vermieden werden soll.Proceeding from this, the object of the invention is to design a combing device of the type mentioned at the outset in such a way that the combing result is further improved, i.e. on the one hand a gentle intervention is made possible and on the other hand a good combing effect, with the combed particles remaining in the combing device to be avoided.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kämmbewe- gung eine Bewegung der Nadeln oder Sägezahnstanzteile mit wenigstens einer Komponente senkrecht zur Kämmbewegung überlagerbar ist.This object is achieved according to the invention in that the combing movement can be superimposed on a movement of the needles or sawtooth punched parts with at least one component perpendicular to the combing movement.
Durch eine überlagerte Bewegung, insbesondere Schwingungsbewegung, senkrecht zur Bewegungsrichtung des Faserbandes und in der Garniturebene, also der durch die Spitzen der Nadeln und Sägestanzteile gebildeten Ebene oder Fläche, wird das Eindringverhalten der Kämmeinrichtung in das Faserband bzw. umgekehrt erheblich verbessert und sanfter gestaltet, so daß mit einer größeren Spitzendichte und verbesserten Eingriffswinkeln gearbeitet werden kann. Gleichzeitig kann durch eine Schwingung in dieser Richtung der Relativabstand benachbarter Nadeln oder Sägezahnstanzteile geändert werden, so daß verklemmte Partikel freigegeben werden.Through a superimposed movement, in particular vibration movement, perpendicular to the direction of movement of the sliver and in the clothing plane, i.e. the plane or surface formed by the tips of the needles and punched parts, the combing device's penetration behavior into the sliver or vice versa is considerably improved and made gentler, so that you can work with a higher tip density and improved pressure angles. At the same time, the relative distance between adjacent needles or saw tooth punch parts can be changed by an oscillation in this direction, so that jammed particles are released.
Durch eine überlagerte Bewegung, insbesondere Schwingungsbewegung, in Richtung senkrecht zur Bewegungsrichtung des Faserbandes und senkrecht zu Fläche der Nadeln oder Sägezahnstanzteilspitzen wird insbesondere eine Förderbewegung in Richtung auf die Spitzen zu, d.h. also vom Boden zwischen benachbarten Nadeln oder Sagezahnstanzteilen weg, erreicht, wodurch ein Lösen festgesetzter Partikel und ein Absondern derselben nach außen gefordert wird.Through a superimposed movement, in particular vibratory movement, in Direction perpendicular to the direction of movement of the sliver and perpendicular to the surface of the needles or sawtooth punched tips, in particular, a conveying movement in the direction of the tips, that is, away from the floor between adjacent needles or sawtooth punched pieces, is achieved, whereby loosening of fixed particles and their separation to the outside is required becomes.
Um sowohl einen sanften Eingriff in das Faserband als auch ein Absondern abgesetzter Partikel zu erreichen, können zwei zueinander senkrechte Bewe- gungskomponenten überlagert werden.In order to achieve both a gentle intervention in the fiber sliver and a separation of separated particles, two mutually perpendicular movement components can be superimposed.
Vorteilhafterweise wird die überlagerte Bewegung der Nadeln oder Sägezahnstanzteile piezoelektrisch, elektromechanisch oder durch einen Exzenter erzeugt, wobei der Antrieb des letzteren abgeleitet vom Antrieb der Auflöse-, Sortier- oder Kämmeinrichtung oder elektromotorisch erfolgen kann.The superimposed movement of the needles or sawtooth punched parts is advantageously generated piezoelectrically, electromechanically or by an eccentric, the latter being driven by the drive of the opening, sorting or combing device or by an electric motor.
Bei einer bevorzugten Ausführungsform ist ein Teil der Nadeln oder Säge- zahnstanzeile feststehend und ein anderer Teil die überlagerte Bewegung ausführend verlagerbar ausgebildet.In a preferred embodiment, part of the needles or sawtooth stamping lines is stationary and another part is designed to be displaceable to carry out the superimposed movement.
Die Nadeln oder Sägezahnsegmente können relativ zu dem jeweiligen Tragkörper schwingend gelagert sein, so daß sie zu einer Eigenschwingung angeregt werden können.The needles or sawtooth segments can be mounted so as to oscillate relative to the respective supporting body, so that they can be excited to vibrate naturally.
Gemäß einer weiteren Ausgestaltung ist vorteilhafterweise vorgesehen, daß die Nadeln oder Sägezahnstanzteile eine Bewegung nach Art einer Schwingfördereinrichtung im wesentlichen in Richtung auf deren Spitze zu ausführen, was insbesondere so realisiert werden kann, daß eine hin- und hergehende Schwingungsbewegung in der Bewegungsphase auf die Spitze zu jäh und in der entgegengesetzten Richtung sanft gebremst wird, so daß die Partikel aufgrund ihrer Trägheit in Richtung Spitze und dementsprechend aus dem Arbeitsbereich der Garnitur gefordert wird.According to a further embodiment, it is advantageously provided that the needles or sawtooth punched parts perform a movement in the manner of an oscillating conveyor device essentially in the direction of the tip thereof, which can in particular be implemented in such a way that a reciprocating oscillating movement in the movement phase is towards the tip suddenly and in the opposite direction is gently braked, so that the particles due to their inertia towards the tip and accordingly from the working area of the set is required.

In Fig. 1 ist schematisch eine Garnitur 1 eines ansonsten nicht veranschaulichten Rundkamms dargestellt, welche aus einer Mehrzahl von Segmenten 2, 3, 4, 5 besteht. Der Rundkamm dreht sich in Richtung des Pfeils 6, wobei das auszukämmende Faserband 7 durch den entsprechend numerierten Pfeil ver- anschaulicht wird.In Fig. 1, a set 1 of an otherwise not illustrated circular comb is shown schematically, which consists of a plurality of segments 2, 3, 4, 5. The circular comb rotates in the direction of arrow 6, the sliver 7 to be combed out being illustrated by the correspondingly numbered arrow.
Das in Kämmrichtung gesehen erste Segment 5, welches also als erstes in das Faserband 7 eingreift, ist in Richtungen senkrecht zur Kämmrichtung (entsprechend den Pfeilen 6 bzw. 6') schwingend antreibbar gelagert, d.h. das Segment 5 kann eine Schwingungsbewegung in Richtung des Pfeils 8 senkrecht zur Zeichenebene und eine Schwingungsbewegung in Richtung des Pfeils 9, also in radialer Richtung bezogen auf den Drehmittelpunkt des Kreiskammes ausführen. Bei der Ausführungsform nach Fig. 2 ist nicht nur das in Kämmrichtung gesehen erste Segment 5, sondern auch das zweite Segment 4 in entsprechender Weise wie in Verbindung mit Fig. 1 erläutert, schwingend antreibbar.The first segment 5 seen in the combing direction, which therefore engages the fiber sliver 7 first, is mounted so as to be drivable in directions perpendicular to the combing direction (corresponding to the arrows 6 and 6 '), ie the segment 5 can oscillate in the direction of the arrow 8 perpendicular to the plane of the drawing and perform an oscillatory movement in the direction of arrow 9, that is to say in the radial direction with respect to the center of rotation of the circular crest. In the embodiment according to FIG. 2, not only the first segment 5 seen in the combing direction, but also the second segment 4 can be driven in a corresponding manner as explained in connection with FIG. 1.
Die entstehende Schwingung ist in Fig. 8 erläutert, wobei die X-Richtung der Schwingung der Richtung des Pfeils 8 und die Y-Richtung der Schwingung der Richtung des Pfeils 9 entspricht, wobei durch die Überlagerung dieser Schwingungsbewegungen die Spitzen 10 der Zähne 11 jedes Sägezahnstanz- teils 12 der Segmente 5 bzw. 4 eine elliptische Schwingung ausführen.The resulting oscillation is explained in FIG. 8, the X direction of the oscillation corresponding to the direction of arrow 8 and the Y direction of the oscillation corresponding to the direction of arrow 9, the tips 10 of the teeth 11 of each saw tooth punch being superimposed by these oscillatory movements - partially 12 of segments 5 and 4 perform an elliptical oscillation.
Durch die Schwingungen bzw. Schwingungskomponenten in Richtung des Pfeils 8 wird ein sanfter schonender Eingriff ermöglicht, wohingegen die Schwingung bzw. Schwingungskomponenten in Richtung des Pfeils 9 dafür sorgen, daß sich absetzende Partikel in Richtung der Spitzen 10 und damit aus der Garnitur hinaus befördert werden.The vibrations or vibrating components in the direction of arrow 8 enable a gentle, gentle intervention, whereas the vibrations or vibrating components in the direction of arrow 9 ensure that settling particles are conveyed in the direction of the tips 10 and thus out of the clothing.
In Fig. 3 ist eine aus Nadeln 13 bestehende Garnitur, beispielsweise eines Fixkamms 14, dargestellt, in der sich ein Partikel 15 abgesetzt hat. Durch eine Schwingungsbewegung in Richtung des Pfeils 16, also in Längsrichtung der Nadeln 13, wird das Partikel 15 gelöst und -nach außen befördert.3 shows a set consisting of needles 13, for example a fixed comb 14, in which a particle 15 has settled. The particle 15 is released and transported to the outside by an oscillating movement in the direction of arrow 16, that is to say in the longitudinal direction of the needles 13.
In Fig. 4 wird veranschaulicht, daß durch eine Schwingungsbewegung in Richtung des Pfeils 17 die Nadeln 13 gemeinsam quer zu ihrer Längserstrek- kung eine Schwingung ausführen, wodurch ein sanftes Eindringen in das Fa- serband bewerkstelligt wird.FIG. 4 illustrates that, by means of a vibration movement in the direction of the arrow 17, the needles 13 jointly execute a vibration transversely to their longitudinal extent, as a result of which a gentle penetration into the fiber ribbon is achieved.
Während bei der Ausführungsform nach Fig. 3 und 4 alle Nadeln 13 der Garnitur 14 gemeinsam schwingen, ist bei den Ausführungsformen nach Fig. 5 bis 7 vorgesehen, daß ein erster Teil der Nadeln 7a feststehend ausgebildet ist und ein zweiter Teil der Nadeln 7b relativ hierzu in Richtung der Pfeile 18, also in deren Längsrichtung beweglich ist.3 and 4 all needles 13 of the clothing 14 swing together, in the embodiments according to FIGS. 5 to 7 it is provided that a first part of the needles 7a is of fixed construction and a second part of the needles 7b is movable relative thereto in the direction of the arrows 18, that is to say in the longitudinal direction thereof.
Bei der Ausführungsform nach Fig. 6 und 7 ist im Unterschied zur Ausfüh- rungsform nach Fig. 5 vorgesehen, daß die beweglichen Nadeln 7b Schultern 19 aufweisen, so daß beim Anheben der Nadeln 7b in Richtung Außenseite diese Schultern 19 mit angehoben und dort befindliche Partikel zuverlässig nach oben transportiert werden. Dabei zeigt Fig. 6 die angehobene Reinigungsposition und Fig. 7 die abgesenkte Grundposition.In the embodiment according to FIGS. 6 and 7, in contrast to the embodiment according to FIG. 5, it is provided that the movable needles 7b have shoulders 19, so that when the needles 7b are lifted towards the outside, these shoulders 19 are also lifted and particles located there can be reliably transported upwards. 6 shows the raised cleaning position and FIG. 7 the lowered basic position.
Die erfindungsgemäß vorgesehene Beweglichkeit der Sägezahnstanzteile 12 und insbesondere der Nadeln 7 setzt eine besonders zuverlässige Befestigung der Nadeln am Nadelträger voraus. Die in den Fig. 9 bis 13 veranschaulichte Befestigungstechnik läßt sich vorteilhaft allerdings auch bei nicht bewegli- chen Garnituren anwenden.The mobility of the sawtooth stamped parts 12 and in particular of the needles 7 provided according to the invention requires a particularly reliable attachment of the needles to the needle carrier. The fastening technology illustrated in FIGS. 9 to 13 can, however, advantageously also be used with non-movable sets.
In Fig. 9 ist ein Nadelträger 20 aus einem unter Druck fließfähigen Material, insbesondere Aluminium, dargestellt, der einen Nut 21 aufweist.FIG. 9 shows a needle carrier 20 made of a material which can flow under pressure, in particular aluminum, and which has a groove 21.
In diese Nut 21 werden, wie sich aus Fig. 10 ergibt, zunächst rein formschlüssig Nadeln 7c eingesetzt und aufgereiht, wobei dann durch zwei Walzen unter Ausbildung der Nuten 22 an der Stirnseite 23 des Nadelträgers 20 eine Materialverdrängung kaltfließend derart bewerkstelligt wird, daß der Kopfbereich 24-der nadeln 7c nicht nur formschlüssig, sondern auch kraft- schlüssig in der Nut 21 festgelegt wird.In this groove 21, as can be seen from FIG. 10, needles 7c are first inserted and lined up in a form-fitting manner, material displacement then being effected in a cold-flowing manner by two rollers with the formation of the grooves 22 on the end face 23 of the needle carrier 20 such that the head region 24-of the needles 7c is not only positively but also non-positively fixed in the groove 21.
In Fig. 11 ist ein fertiger Nadelstreifen 25 dargestellt, bei welchem die Preßrollen nicht von der Stirnseite her, sondern von der Seite unter Ausbildung von Nuten 26 angegriffen haben und so den Nadelkopf 24 festlegen. Fig. 12 zeigt eine Ausführungsform eines Nadelstreifens entsprechend Fig. 9 mit einer im Querschnitt rechteckigen Nut 21, der für die Befestigungstechnik nach Fig. 11 geeignet ist.11 shows a finished pin strip 25, in which the pressure rollers have not acted from the front side but from the side with the formation of grooves 26 and thus fix the pin head 24. FIG. 12 shows an embodiment of a pinstripe corresponding to FIG. 9 with a groove 21 which is rectangular in cross section and which is suitable for the fastening technology according to FIG. 11.
Eine alternative Ausführungsform ist in Fig. 13 dargestellt, wo die Nut 21a im Querschnitt schwalbenschwanzförmig ausgebildet ist, so daß beim Aufreihen der Kopfbereiche 24 der Nadeln 7c bereits sichergestellt ist, daß die Nadeln 7c nach unten nicht herausfallen können. An alternative embodiment is shown in FIG. 13, where the groove 21a is dovetail-shaped in cross section, so that when the head regions 24 of the needles 7c are lined up, it is already ensured that the needles 7c cannot fall out downwards.
