Abstract

A bobbin winding assembly has a finger-guide traversing the width of the rotating cross-wound bobbin. On reaching the outer margin the finger (13) reverses direction. The finger moves under the influence near the point of reversal under the influence of two stationary permanent magnets (30, 31) that store potential energy prior to the reversal point and surrender potential after the reversal point. The magnets are arranged with like poles in close proximity to the motor shaft (39) left and right of the finger (13) movement arc. When the drive motor (14) is off the magnets return the finger guide to the mid-point. The two stationary permanent magnets and a permanent magnet moving with the finger all have the same radial distance fro the swivel axis.

Description

Die Erfindung betrifft einen Energiespeicher gemäß dem Oberbegriff des Anspruches 1.The invention relates to an energy store according to the Preamble of claim 1.

Es ist bekannt, daß zur Herstellung von Textilspulen wenigstens zwei Voraussetzungen erfüllt sein müssen. Zum einen muß die Textilspule in Rotation versetzt und zum anderen muß der auf die rotierende Textilspule auflaufende Faden längs der Spulenachse traversiert werden. Wenn der Faden dabei sehr langsam traversiert wird, entsteht eine Textilspule mit weitestgehend parallelen Wicklungen. Soll eine solche Textilspule ein größeres Volumen und im wesentlichen rechtwinklig zur Spulenachse angeordnete flache Stirnseiten besitzen, sind beidseits der Wicklungen Begrenzungsscheiben erforderlich.
Diese Begrenzungsscheiben können vermieden werden, wenn der Faden so schnell traversiert wird, daß sich eine Kreuzbewicklung ergibt.
Da moderne Textilmaschinen bei der Herstellung von Kreuzspulen bekanntlich mit relativ hohen Wicklungsgeschwindigkeiten arbeiten, ist auch bei der Traversierung des auflaufenden Fadens eine sehr hohe Traversierrate erforderlich.It is known that for the production of textile spools at least two conditions must be met. On the one hand, the textile spool must be set in rotation and, on the other hand, the yarn running onto the rotating textile spool must be traversed along the spool axis. If the thread is traversed very slowly, a textile spool is formed with largely parallel windings. If such a textile bobbin has a larger volume and substantially perpendicular to the coil axis arranged flat end faces, boundary plates are required on both sides of the windings.
These limiting discs can be avoided if the thread is traversed so fast that there is a Kreuzbewicklung.
Since modern textile machines work in the production of cheeses known with relatively high winding speeds, a very high traversing rate is required even when traversing the running thread.

Im Zusammenhang mit der Traversierung von Fäden bei der Herstellung von sogenannten Kreuzspulen sind Changiereinrichtungen in den unterschiedlichsten Ausführungsformen bekannt. In connection with the traversal of threads in the Production of so-called cheeses are Changiereinrichtungen in the most diverse Embodiments known.

Neben sogenannten Riemchenfadenführern sind beispielsweise bevorzugt als Nuttrommeln ausgebildete Fadenführungstrommeln oder auch Fingerfadenführer im Einsatz. Derartige Fingerfadenführer werden dabei in der Regel jeweils über einen separaten elektromechanischen Antrieb beaufschlagt.In addition to so-called Riemchenfadenführern are, for example preferably formed as grooving thread guide drums or Fingerfadenführer in use. Such finger thread guides are usually each acted upon by a separate electromechanical drive.

In der EP 0 838 422 A1 ist beispielsweise ein Fingerfadenführer beschrieben, der durch einen solchen separaten elektromechanischen Antrieb beaufschlagt wird. Im Bereich der Hubenden des Fingerfadenführers sind außerdem Energiespeicher in Form von Schraubenfedern angeordnet, die die Bewegungsrichtungsumkehr des Fadenführers unterstützen und dabei sowohl dessen Antrieb entlasten als auch die Verweilzeit des Fadenführers an den Hubenden verringern sollen. Die Energiespeicher sind in ihrer Position mechanisch verstellbar, so daß der Hub des Fadenführers verstellt werden kann, um zum Beispiel aufgewölbte Kanten an der Kreuzspule zu vermeiden.In EP 0 838 422 A1, for example, a Finger thread guide described by such a separate electromechanical drive is applied. In the area of the stroke ends of the finger thread guide are also Energy storage arranged in the form of coil springs, the Support the direction of movement of the yarn guide and thereby relieve both its drive and the residence time to reduce the thread guide at the stroke ends. The energy stores are mechanical in their position adjustable, so that the stroke of the thread guide can be adjusted can, for example, to curved edges on the cheese too avoid.

Derartige Energiespeicher weisen allerdings verschiedene Nachteile auf.
Durch das relativ ruckartige Abbremsen des Fadenführers beim Auftreffen auf den jeweiligen Energiespeicher wird beispielsweise das gesamte Verlegesystem auf das höchste beansprucht und muß daher eine erhebliche Stabilität aufweisen, was die Masse und damit die Massenträgheit des Verlegesystems signifikant erhöht.
Bei Changierfrequenzen von 30 Hz und mehr spielt jedoch die Massenträgheit bereits eine erhebliche Rolle für den Antrieb. Des weiteren wird beim Aufschlagen des Fadenführers auf die Energiespeicher ein Geräusch erzeugt, das sich bei langen Textilmaschinen mit vielen derartigen Verlegesystemen entsprechend aufsummiert.
Wenn der Antrieb des Fadenführers durch einen Regler kontrolliert wird, ergeben sich im Bereich des Eintauchens des Fadenführers in die Energiespeicher außerdem Lastsprünge, die die Regelgüte des Reglers erheblich beeinträchtigen.However, such energy storage devices have various disadvantages.
Due to the relatively sudden braking of the yarn guide when hitting the respective energy storage, for example, the entire installation system is stressed to the highest and must therefore have considerable stability, which significantly increases the mass and thus the inertia of the installation system.
At traversing frequencies of 30 Hz and more, however, the inertia already plays a significant role for the drive. Furthermore, when the thread guide hits the energy store, a noise is generated which accumulates accordingly in long textile machines with many such laying systems.
If the drive of the thread guide is controlled by a controller, resulting in the area of immersion of the thread guide in the energy storage also load jumps, which significantly affect the control performance of the controller.

Es ist deshalb bereits vorgeschlagen worden, Energiespeicher einzusetzen, deren potentielle Energie zu den Umkehrpunkten des Fingerfadenführers hin stetig zunimmt.It has therefore already been proposed energy storage to use their potential energy at the reversal points of the finger thread guide steadily increases.

Die DE 199 60 024 A1 beschreibt einen solchen Fingerfadenführer, der durch einen elektromechanischen Antrieb beaufschlagt wird und gleichzeitig mit wenigstens einer am Antriebsgehäuse festgelegten Drehfeder, vorzugsweise einer Spiralfeder, verbunden ist.
Da die potentielle Energie einer solchen Spiralfeder zu' den Totpunkten des Traversierbereiches hin stetig zunimmt, bildet ein angetriebener Fingerfadenführer, an den eine solche Spiralfeder angeschlossen ist, ein im wesentlichen harmonisch oszillierendes mechanisches System.DE 199 60 024 A1 describes such a finger thread guide, which is acted upon by an electromechanical drive and at the same time with at least one fixed to the drive housing torsion spring, preferably a coil spring, is connected.
Since the potential energy of such a coil spring steadily increases toward the dead centers of the traverse region, a driven finger thread guide, to which such a spiral spring is connected, forms a substantially harmoniously oscillating mechanical system.

Als möglicher Schwachpunkt einer solchen sowohl in der Theorie als auch in der Praxis einwandfrei arbeitenden und gut regelbaren Changiereinrichtung wurde allerdings die Drehfeder ausgemacht, deren Lebensdauer den hohen Anforderungen, die an solche Verlegesysteme gestellt werden, möglicherweise nicht mit ausreichender Sicherheit genügen kann. As a possible weak point of such in both theory as well as working well in practice and good adjustable traversing device, however, was the torsion spring whose life meets the high standards required such laying systems may not be provided can suffice with sufficient certainty.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, einen Energiespeicher der vorbeschriebenen Gattung so weiter zu entwickeln, daß einerseits die potentielle Energie dieses Energiespeichers zu den Totpunkten des Traversierbereiches hin stetig zunimmt'und anderseits eine hohe Lebensdauer des Energiespeichers gewährleistet ist.Based on the aforementioned prior art is the Invention therefore an object of an energy storage the type described above to develop so that on the one hand, the potential energy of this energy storage the dead centers of the traversing area increases steadily 'and on the other hand, a long life of the energy storage is guaranteed.

Diese Aufgabe wird erfindungsgemäß durch einen Energiespeicher gelöst, der die im Kennzeichen des Anspruches 1 beschriebenen Merkmale aufweist.This object is achieved by an energy storage solved, those described in the characterizing part of claim 1 Features.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Dependent claims.

Der Einsatz eines magnetischen Energiespeichers, der wenigstens zwei stationäre und einen mit dem Fadenführer traversierbaren Permanentmagnet aufweist, hat den Vorteil, daß eine solche Einrichtung keiner mechanischen Abnutzung unterliegt und daher eine nahezu unbegrenzte Lebensdauer besitzt.
Des weiteren sind solche Energiespeicher relativ kostengünstig herstellbar und arbeiten unter allen Betriebsbedingungen äußerst zuverlässig.The use of a magnetic energy store, which has at least two stationary and traversable with the yarn guide permanent magnet, has the advantage that such a device is not subject to mechanical wear and therefore has a virtually unlimited lifetime.
Furthermore, such energy storage are relatively inexpensive to produce and work extremely reliable under all operating conditions.

In vorteilhafter Ausführungsform sind die beiden stationären Permanentmagnete, wie in den Ansprüchen 2 und 3 beschrieben, in eine Magnetaufnahmeplatte integriert, die ihrerseits endseitig am Motorgehäuse des elektromechanischen Antriebes des Fingerfadenführers festgelegt ist. In an advantageous embodiment, the two stationary Permanent magnets as described in claims 2 and 3, integrated into a magnetic recording plate, which in turn at the end of the motor housing of the electromechanical drive of the Fingerfadenführers is fixed.

Die Magnetaufnahmeplatte weist dabei eine Grundplatte und zwei die Grundplatte nach hinten überragende Lagerkonsolen mit Lagerbohrungen für die stationären Permanentmagnete auf.
Eine derartig ausgebildete Magnetaufnahmeplatte stellt während des Spulbetriebes ein stabiles Widerlager für die zwischen den Permanentmagneten auftretenden Magnetkräfte dar.
Außerdem ist eine solche Magnetaufnahmeplatte, beispielsweise im Druckguß- oder Spritzgußverfahren, kostengünstig herzustellen und kann über Schraubenbolzen oder dgl. leicht und zuverlässig am Motorgehäuse des Fadenführerantriebes festgelegt werden (Anspruch 4).The magnetic recording plate in this case has a base plate and two bearing brackets projecting rearwardly with bearing bores for bearing bores for the stationary permanent magnets.
Such a trained magnetic recording plate provides during the winding operation is a stable abutment for the magnetic forces occurring between the permanent magnets.
In addition, such a magnetic recording plate, for example, in the die casting or injection molding process, inexpensive to manufacture and can be easily and reliably fixed to the motor housing of the thread guide drive via bolts or the like. (Claim 4).

Wie im Anspruch 5 beschrieben, ist der traversierbare Permanentmagnet in eine Schaltfahne integriert, die ihrerseits drehfest mit der Motorwelle des Fadenführerantriebes verbunden ist.
Auch die Schaltfahne ist dabei vorteilhafterweise mittels Schraubenbolzen an der Motorwelle festgelegt (Anspruch 6). Die im Zusammenhang mit den Ansprüchen 2 bis 4 beschriebenen Vorteile gelten im übrigen auch für die Ansprüche 5 und 6.As described in claim 5, the traversable permanent magnet is integrated in a switching lug, which in turn is rotatably connected to the motor shaft of the thread guide drive.
The switching lug is advantageously determined by means of bolts on the motor shaft (claim 6). The advantages described in connection with claims 2 to 4 also apply to claims 5 and 6.

Die im Anspruch 7 beschriebene Ausführungsform ist zwingend notwendig, da nur bei einer solchen Ausrichtung der Pole der Permanentmagnete der gewünschte Effekt eines magnetischen Energiespeichers, der die Bewegungsrichtungumkehr des Fingerfadenführers unterstützt, erzielbar ist.The embodiment described in claim 7 is mandatory necessary, since only in such an orientation of the poles of Permanent magnets the desired effect of a magnetic Energy storage device that reverses the direction of movement Fingerfadenführers supported, achievable.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. The invention will be described below with reference to the drawings illustrated embodiment illustrated.

In Figur 1 ist in Seitenansicht schematisch die Arbeitsstelle 2 einer Kreuzspulen herstellenden Textilmaschine dargestellt. Es handelt sich im vorliegenden Fall um einen sogenannten Kreuzspulautomaten 1. Auf den Arbeitsstellen 2 derartiger Kreuzspulautomaten 1 werden, wie bekannt und daher nicht näher erläutert, die auf einer Ringspinnmaschine produzierten Spinnkopse 3 zu großvolumigen Kreuzspulen 5 umgespult.
Die Kreuzspulen 5 werden nach ihrer Fertigstellung mittels eines (nicht dargestellten) selbsttätig arbeitenden Serviceaggregates, vorzugsweise eines Kreuzspulenwechslers, auf eine maschinenlange Kreuzspulentransporteinrichtung 7 übergeben und zu einer maschinenendseitig angeordneten Spulenverladestation oder dergleichen transportiert.FIG. 1 schematically shows a side view of the workstation 2 of a textile machine producing cross-wound bobbins. It is in the present case to a so-called cheese winder 1. On the jobs 2 such automatic cheese 1, as is well known and therefore not explained in more detail, produced on a ring spinning machine spinning cops 3 rewound to large-volume cheeses 5.
The cheeses 5 are after their completion by means of a (not shown) automatically operating service unit, preferably a cheese changer, handed over to a machine-length cheese package transport means 7 and transported to a machine end side Spulenverladestation or the like.

Solche Kreuzspulautomaten 1 weisen in der Regel außerdem eine Logistikeinrichtung in Form eines Spulen- und Hülsentransportsystems 6 auf. In diesem Spulen- und Hülsentransportsystem 6 laufen, auf Transporttellern 11, die Spinnkopse 3 beziehungsweise Leerhülsen um.
Von dem Hülsentransportsystem 6 sind in Figur 1 lediglich die Kopszuführstrecke 24, die reversierend antreibbare Speicherstrecke 25, eine der zu den Spulstellen 2 führenden Quertransportstrecken 26 sowie die Hülsenrückführstrecke 27 dargestellt.As a rule, such automatic packages 1 also have a logistics device in the form of a package and tube transport system 6. In this bobbin and tube transport system 6 run on transport plates 11, the spinning cops 3 or empty tubes to.
Of the tube transport system 6 are shown in Figure 1, only the Kopszuführstrecke 24, the reversibly driven storage section 25, one of the leading to the winding units 2 transverse transport sections 26 and the sleeve return path 27.

Die einzelnen Spulstellen verfügen des weiteren, wie bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitsstellen 2 gewährleisten.
Eine dieser Einrichtungen ist beispielsweise die Spulvorrichtung 4. Wie üblich, besitzt die Spulvorrichtung 4 einen Spulenrahmen 8, der um eine Schwenkachse 12 beweglich gelagert ist und der, zum Beispiel zur Fertigung von konischen Kreuzspulen, um eine weitere, orthogonal zur Schwenkachse 12 angeordnete Achse verschwenkbar sein kann.The individual winding units furthermore have, as is known and therefore only indicated, various devices which ensure the proper operation of these work stations 2.
One of these devices is, for example, the winding device 4. As usual, the winding device 4 has a coil frame 8 which is movably mounted about a pivot axis 12 and which, for example for the production of conical cheeses, pivotable about a further, orthogonal to the pivot axis 12 arranged axis can be.

In dem in Fig.1 dargestellten Ausführungsbeispiel liegt die Kreuzspule 5 während des Spulbetriebes mit ihrer Oberfläche auf einer Stütz- und Andrückwalze 9 auf und nimmt diese antriebslose Stütz- und Andrückwalze 9 über, Reibschluß mit. Der Antrieb der Kreuzspule erfolgt in diesem Fall über eine (nicht dargestellte) drehzahlregelbare Antriebseinrichtung, die direkt am Spulenrahmen 8 angeordnet beziehungsweise in den Spulenrahmen 8 integriert ist.
In alternativer Ausführungsform kann selbstverständlich auch eine angetriebene Andrückwalze vorgesehen sein, die dann die im Spulenrahmen freirotierbar gelagerte Kreuzspule reibschlüssig antreibt. In the embodiment shown in Figure 1, the cheese 5 is located during the winding operation with its surface on a support and pressure roller 9 and takes these unpowered support and pressure roller 9, frictional engagement with. The drive of the cross-wound bobbin in this case via a (not shown) speed-adjustable drive means which is arranged directly on the creel 8 or integrated into the creel 8.
In an alternative embodiment, of course, a driven pressure roller can be provided, which then frictionally drives the cross-coil freely rotatably mounted in the coil frame.

Zur Changierung des Fadens 16 während des Spulprozesses ist eine Fadenchangiereinrichtung 10 vorgesehen.
Eine solche in der Figur 1 schematisch angedeutete Fadenchangiereinrichtung 10 ist beispielsweise in der DE 199 60 024 A1 relativ ausführlich beschrieben.
Die Fadenchangiereinrichtung 10 besteht im wesentlichen aus einem fingerartig ausgebildeten Fadenführer 13, der, durch einen elektromechanischen Antrieb 14 beaufschlagt, den Faden 16 zwischen den Stirnseiten der Kreuzspule 5 traversiert.
Wie in Fig.1 weiter angedeutet, ist der elektromechanische Antrieb 14 außerdem mit einem erfindungsgemäßen magnetischen Energiespeicher 20 ausgestattet.For traversing the thread 16 during the winding process a Fadenchangiereinrichtung 10 is provided.
Such a thread-changing device 10 schematically indicated in FIG. 1 is described in relatively detail, for example, in DE 199 60 024 A1.
The Fadenchangiereinrichtung 10 consists essentially of a finger-like thread guide 13, which, acted upon by an electromechanical drive 14, the thread 16 traversed between the end faces of the cheese 5.
As further indicated in FIG. 1, the electromechanical drive 14 is also equipped with a magnetic energy store 20 according to the invention.

Jede Arbeitsstelle 2 des Kreuzspulautomaten 1 weist außerdem einen Arbeitsstellenrechner 28 auf, der über eine Busverbindung 15 an eine Zentralsteuereinheit 17 angeschlossen ist.
Die pneumatische Versorgung der Arbeitsstellen 2 erfolgt über eine Sauglufttraverse 18, die beispielsweise über eine Unterdruckleitung 19 mit einer Unterdruckquelle 21 in Verbindung steht.Each workstation 2 of the automatic winder 1 also has a workstations computer 28 which is connected to a central control unit 17 via a bus connection 15.
The pneumatic supply to the work stations 2 via a Sauglufttraverse 18, which is for example via a vacuum line 19 with a vacuum source 21 in conjunction.

Der in Figur 1 nur angedeutete, mit einem magnetischen Energiespeicher 20 ausgestattete elektromechanische Antrieb 14 für den Fingerfadenführer 13 ist in Figur 2 perspektivisch dargestellt.
Wie ersichtlich, weist der Antrieb 14 ein Motorgehäuse 22 mit einem rückseitigen Befestigungsflansch 23 auf. Über die Langlochbohrungen 28 im Befestigungsflansch 23 kann der Antrieb 14 am Spulstellengehäuse 29 festgelegt werden. The only indicated in Figure 1, equipped with a magnetic energy storage 20 electromechanical drive 14 for the finger thread guide 13 is shown in perspective in Figure 2.
As can be seen, the drive 14 has a motor housing 22 with a rear mounting flange 23. About the slot holes 28 in the mounting flange 23, the drive 14 can be set on the winding head housing 29.

Der erfindungsgemäße magnetische Energiespeicher 20 weist wenigstens zwei stationäre Permanentmagnete 30, 31 sowie wenigstens einen mit dem Fadenführer 13 reversierbaren Permanentmagnet 32 auf.The magnetic energy store 20 according to the invention has at least two stationary permanent magnets 30, 31 and at least one reversible with the yarn guide 13 Permanent magnet 32 on.

Die stationären Permanentmagnete 30, 31 sind dabei in eine Magnetaufnahmeplatte 33 integriert, deren Grundplatte 41 z.B. über Schraubenbolzen 34 am Motorgehäuse 22 des elektromechanischen Antriebes 14 festlegbar ist.
Die Grundplatte 41 der Magnetaufnahmeplatte 33 weist zur Aufnahme der Permanentmagnete 30, 31 zwei einstückig angeformte Lagerkonsolen 35A beziehungsweise 35B mit entsprechenden Lagerbohrungen 36A beziehungsweise 36B auf. In diesen Lagerbohrungen 35A bzw. 35B sind die stationären Permanentmagnete 30 bzw. 31 festgelegt.The stationary permanent magnets 30, 31 are integrated into a magnetic receiving plate 33, the base plate 41 can be fixed for example by means of bolts 34 on the motor housing 22 of the electromechanical drive 14.
The base plate 41 of the magnetic receiving plate 33 has for receiving the permanent magnets 30, 31 two integrally molded bearing brackets 35A and 35B with corresponding bearing bores 36A and 36B. In these bearing bores 35A and 35B, the stationary permanent magnets 30 and 31 are fixed.

Des weiteren ist im Bereich zwischen den Lagerkonsolen 35A beziehungsweise 35B eine bewegliche Schaltfahne 37 angeordnet, die, vorzugsweise ebenfalls über entsprechende Schraubenbolzen 38, drehfest auf der Motorwelle 39 des Antriebes 14 des Fingerfadenführers 13 festlegbar ist. Die Schaltfahne 37 weist eine Durchgangsbohrung 40 zur Aufnahme des traversieren Permanentmagneten 32 auf.
Die Permanentmagnete 30, 31, 32 sind in ihren entsprechenden Lagerstellen so angeordnet, daß sich jeweils gegensinnige Pole gegenüberstehen.Furthermore, a movable switching lug 37 is arranged in the region between the bearing brackets 35 A and 35 B, which, preferably also via corresponding bolts 38, rotatably on the motor shaft 39 of the drive 14 of the finger thread guide 13 can be fixed. The switching lug 37 has a through hole 40 for receiving the traversed permanent magnet 32.
The permanent magnets 30, 31, 32 are arranged in their respective bearing points so that each opposing poles face each other.

Das heißt, zwischen den stationären Permanentmagneten 30, 31 und dem traversierbar gelagerten Permanentmagnet 32 bestehen permanent Magnetkräfte, die im Sinne "abstoßen" wirken. That is, between the stationary permanent magnets 30, 31 and the traversably mounted permanent magnet 32 exist Permanent magnetic forces that act in the sense of "repelling".

Die auf den traversierbaren Permanentmagnet 32 einwirkenden Magnetkräfte 'heben sich in der Mittellage des Fadenführers 13 und damit auch der Schaltfahne 37 gegenseitig auf.
Bei einer Traversierung des Fadenführers 13, zum Beispiel zum Umkehrpunkt U1 hin, nimmt die potentielle Energie der abstoßenden Magnetkräfte zwischen dem Südpol S des Permanentmagneten 30 und dem Südpol S des Permanentmagneten 32 stetig zu, während gleichzeitig die potentielle Energie der Magnetkräfte zwischen den Nordpolen N der Permanentmagnete 32 und 31 abnimmt. Die maximale potentielle Energie wird jeweils in den Umkehrpunkten U1 und U2 erreicht und zur erneuten Beschleunigung des Fadenführers 13 in seine entgegengesetzte Richtung benutzt.The force acting on the traversable permanent magnet 32 magnetic forces' cancel each other in the middle position of the yarn guide 13 and thus also the switching lug 37.
In a traversal of the yarn guide 13, for example, to the reversal point U 1 back, the potential energy of the repulsive magnetic forces between the south pole S of the permanent magnet 30 and the south pole S of the permanent magnet 32 steadily increases, while the potential energy of the magnetic forces between the north poles N the permanent magnets 32 and 31 decreases. The maximum potential energy is achieved in each case in the reversal points U 1 and U 2 and used for renewed acceleration of the yarn guide 13 in its opposite direction.
