Abstract

Thread tensioning pegs (14, 14', 14'') and electrical coil (18) occupy a common swinging arm (10). The coil swings in an air gap surrounding it, with a magnet arrangement producing magnetic flux. This penetrates the air gap at right angles. Preferred features: The swinging arm is double. A first arm carries the thread tensioners, a second the coil. Disposition of coil and tensioners (a series of pegs swinging with the arm) is diametral with respect to the axis of pivoting. Coil and magnets produce a torque on the arm which is proportional to the current. At least two magnets are used; especially permanent magnets.

Description

Die Erfindung betrifft eine Vorrichtung zur Steuerung der Fadenzugkraft eines laufenden Fadens in einer automatischen Wickeleinrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for controlling the Thread tension of a running thread in an automatic Winding device according to the preamble of claim 1.

Es ist aus der DE 37 34 471 bekannt, zwischen einer Ablaufspule und einer Auflaufspule eines Spulautomaten die Fadenzugkraft mittels eines Rechenspanners derart zu steuern, daß die Bremskraft- beziehungsweise die Fadenzugkrafterhöhung, die der Rechenspanner auf den Faden aufbringt, verringert wird, wenn die Drehzahl der Auflaufspule einen vorbestimmten Schwellwert erreicht hat. Die verstellbaren Fadenspannelemente des Rechenspanners lassen sich mittels eines Elektromotors verstellen. Bei einem derartigen Antriebsmechanismus wird die Vorwärts- oder Zurückbewegung der verstellbaren Fadenspannelemente über eine Getriebeeinrichtung erzeugt, die die Drehbewegung des Motors in eine lineare Bewegung umsetzt.It is known from DE 37 34 471, between a payout spool and a package of an automatic winder the thread tension to be controlled by means of a calculator so that the Braking force or the thread tension increase that the Rake on the thread is reduced when the speed of the package a predetermined threshold has reached. The adjustable thread tensioning elements of the Rake clamps can be operated using an electric motor adjust. With such a drive mechanism Forward or backward movement of the adjustable Thread tensioning elements generated via a gear device, the converts the rotary motion of the motor into a linear motion.

Die nicht vorveröffentlichte DE 198 58 548 beschreibt eine Changiervorrichtung zum Zuführen eines Fadens zu einer rotierend angetriebenen Kreuzspule mit einem Changierfadenführer, der um eine senkrecht zur Kreuzspulenachse angeordnete Drehachse schwenkbar ist. Das den Faden führende Ende des Changierfadenführers wird durch eine elektrische Spule hin- und herbewegt, wobei die Spule in einem Magnetfeld angeordnet ist und die Changierbewegung des Changierfadenführers zur Verlegung des Fadens auf einer Kreuzspule erzeugt und steuert. The unpublished DE 198 58 548 describes one Traversing device for feeding a thread to one rotatably driven cheese with a Traversing thread guide, which is perpendicular to the package axis arranged axis of rotation is pivotable. The leading thread The traversing thread guide ends by an electrical coil reciprocating, the coil in a magnetic field is arranged and the traversing movement of the Traversing thread guide for laying the thread on a Cross-wound package generates and controls.

Die gattungsbildende DE 43 35 089 beschreibt eine Vorrichtung zum Steuern der Fadenspannung, mittels der die Garnspannung schrittweise auf einen gewünschten Wert erhöht oder verringert werden kann, zum Beispiel zum Ausgleich einer erhöhten Abspulspannung. Die Vorrichtung zum Steuern der Fadenspannung ist Teil einer automatischen Wickeleinrichtung. Um den Aufwand, der beim Einsatz einer derartigen Vorrichtung in jeder einzelnen Wickeleinheit der Spulmaschine erforderlich wäre, zu vermeiden, wird ein Ausgabesignal zur Steuerung der Fadenspannung an einer spezifischen Spindel gewonnen und eine Vielzahl weiterer Spindeln der Spulmaschine aufgrund dieses Ausgabesignals gesteuert. Eine als Rechenspanner wirkende Spannvorrichtung mit einem Paar zusammenwirkender kammförmiger Teile weist ein Solenoid auf, das über eine Gestängeeinrichtung und einen Exzenter den Eingriffsgrad der Kämme in den Fadenlauf und damit das Maß des Kontaktwinkels des Fadens bezüglich der Kammzähne einstellt.The generic DE 43 35 089 describes a device to control the thread tension by means of which the thread tension gradually increased or decreased to a desired value can be used, for example, to compensate for an increased Unwinding tension. The device for controlling the thread tension is part of an automatic winding device. To the effort that when using such a device in everyone individual winding unit of the winding machine would be required avoid an output signal to control the Thread tension obtained on a specific spindle and a Many other spindles of the winding machine due to this Output signals controlled. One that works as a calculator Clamping device with a pair of cooperating comb-shaped Parts has a solenoid that operates through a linkage and an eccentric the degree of engagement of the combs in the thread course and thus the measure of the contact angle of the thread with respect to Comb teeth sets.

Es liegt eine relativ hohe Massenträgheit der bewegten Teile sowie ein Getriebespiel beziehungsweise ein Spiel in den Übertragungselementen bei den vorbeschriebenen üblichen Rechenspannern vor. Wegen der dadurch verursachten Regelträgheit neigen derartige Fadenspanner dazu, die Spitzenwerte der Fadenzugkraft zu erhöhen und die Qualität der Regelung zu beeinträchtigen.There is a relatively high mass inertia of the moving parts as well as a gear game or a game in the Transmission elements in the usual Calculators before. Because of the caused by it Inertia such thread tensioners tend to Peak values of thread tension increase and the quality of the Affect regulation.

Aus der DE 195 44 202 ist eine Vorrichtung zum Spannen von Garn bekannt, mit der die Fadenzugkraft auf einen Sollwert eingeregelt wird. Die Fadenzugkraftregelung ist so ausgebildet, daß der Rechenspanner sowohl eine Funktion als Spanner als auch eine Funktion als Fadenzugkraftsensor erfüllt. Das Verstellen der verstellbaren Fadenspannelemente erfolgt mittels eines elektrodynamischen Antriebes, der als Tauchspulen-Topfmagnet-Anordnung ausgebildet ist. Ein Halter mit verstellbaren fingerartigen Fadenspannelementen ist mit einer quer zur Fadenlaufrichtung ausgerichteten Stange verbunden, die axial verschiebbar in Lagerbuchsen gelagert ist. Linearlagerungen weisen den Nachteil auf, verschmutzungsempfindlich zu sein. Dieser Nachteil macht sich besonders bemerkbar wegen der an den Arbeitsstellen unvermeidbaren Staubentwicklung und wirkt sich verstärkt beim Einsatz von auf den laufenden Faden aufgebrachten Avivagen aus. Ein derartiges System weist auch eine noch relativ hohe Massenträgheit auf. Die gesamte Masse der Tauchspule und des Halters muß über den gesamten Verstellweg bewegt werden. Dies behindert die Reaktion auf hochfrequente Fadenzugkraftschwankungen und kann auftretende Fadenzugkraftspitzen erhöhen. Dies wirkt sich nachteilig auf die Funktion der Vorrichtung aus.DE 195 44 202 describes a device for tensioning yarn known with which the thread tension to a setpoint is regulated. The thread tension control is designed so that the screen tensioner has both a function as a tensioner as well fulfills a function as a thread tension sensor. The adjustment the adjustable thread tensioning elements are made by means of a electrodynamic drive, as a moving coil pot magnet arrangement is trained. A holder with adjustable finger-like thread tensioning elements is with one across Thread running aligned rod connected axially is slidably mounted in bearing bushes. Linear bearings have the disadvantage of being sensitive to contamination. This disadvantage is particularly noticeable because of the on the Work places inevitable dust and affects reinforced when using up-to-date thread applied finishings. Such a system also has a relatively high inertia. The entire mass the moving coil and the holder must cover the whole Adjustment path can be moved. This hampers the response to high frequency thread tension fluctuations and can occur Increase thread tension peaks. This has an adverse effect the function of the device.

Es ist Aufgabe der Erfindung, eine gattungsgemäße Vorrichtung zur Steuerung der Fadenzugkraft zu verbessern. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.It is an object of the invention to provide a generic device to improve thread tension control. This task is achieved according to the invention by the features of claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are Subject of the subclaims.

Eine erfindungsgemäße Vorrichtung mit verstellbaren Fadenspannelementen des Rechenspanners und der elektrischen Spule auf einem gemeinsamen Schwenkhebel weist keine die Regelträgheit erhöhende Übertragungsmittel und kein Übertragungsspiel auf. Das durch die elektrische Spule erzeugte Drehmoment wirkt sich unmittelbar über die verstellbaren Fadenspannelemente aus. Die Steuerung der Fadenspannung kann ohne Zeitverzögerung und ohne nennenswerte Reibungsverluste erfolgen. Das geringe Trägheitsmoment der zu bewegenden Teile erlaubt eine schnelle Reaktion bei hochfrequenten Spannungsveränderungen. Durch die schnelle Reaktion beziehungsweise die geringe Regelträgheit ist die erfindungsgemäße Vorrichtung in der Lage, in gewünschter Weise selbstregelnd zu wirken und arbeitet auch bei auftretenden hochfrequenten Fadenspannungsspitzen zufriedenstellend. Es lassen sich relativ hohe Drehmomente zur Steuerung des Schwenkhebels bei geringen Schwenkwegen und im Vergleich dazu großen Verstellwegen der verstellbaren Fadenspannelemente erzielen. Die verstellbaren Fadenspannelemente können dazu relativ weit von der Schwenkachse des Schwenkhebels auf dem Hebelarm angeordnet sein und der betreffende Hebelarm entsprechend lang und sehr leicht ausgeführt sein. Die Leistungsfähigkeit der erfindungsgemäßen Vorrichtung beim Aufbringen eines erforderlichen Drehmomentes auf den Schwenkhebel ist groß. Die elektrische Spule kann daher relativ nahe an der Schwenkachse angeordnet sein. Ein für eine wirkungsvolle Steuerung der Fadenspannung ausreichendes Moment kann bereits mit einer baulich sehr klein ausgeführten Vorrichtung erzeugt werden. Die kompakte, konstruktiv einfache Bauweise, die nur geringen baulichen Aufwand erfordert, ist bei Maschinen mit einer Vielzahl von Arbeitsstellen, wie sie Spinn- und Spulmaschinen darstellen, von großem Vorteil. Der damit einhergehende geringe Platzbedarf der Vorrichtung ist bei dem begrenzten zur Verfügung stehenden Raum an derartigen Arbeitsstellen äußerst willkommen.A device according to the invention with adjustable Thread tensioning elements of the slide tensioner and the electrical None on a common swivel lever has the coil Transmission means increasing inertia and none Transfer game on. That generated by the electrical coil Torque affects the adjustable directly Thread tensioning elements. The control of the thread tension can without time delay and without significant friction losses respectively. The low moment of inertia of the parts to be moved allows a quick reaction to high-frequency Voltage changes. Because of the quick reaction or the low inertia is The device according to the invention is able in the desired manner to act self-regulating and also works for those who occur high-frequency thread tension peaks satisfactory. It relatively high torques can be used to control the Swivel lever with short swivel paths and in comparison large adjustment paths of the adjustable thread tensioning elements achieve. The adjustable thread tensioning elements can do this relatively far from the pivot axis of the pivot lever on the Lever arm be arranged and the relevant lever arm be made correspondingly long and very light. The Performance of the device according to the invention Applying a required torque to the Swing lever is big. The electrical coil can therefore be relative be arranged close to the pivot axis. One for one effective control of thread tension sufficient moment can already be built with a very small construction Device are generated. The compact, structurally simple Construction, which requires little construction effort, is at Machines with a variety of workplaces, such as spinning and represent winding machines, of great advantage. The one with it accompanying small space requirement of the device is in the limited space available on such Jobs extremely welcome.

Der als beweglicher Teil der erfindungsgemäßen Vorrichtung ausgeführte Schwenkhebel ist mittels eines Drehlagers, insbesondere eines Wälzlagers, und damit besonders reibungsarm gelagert. Ein Drehlager läßt sich besser abdichten und ist deutlich weniger verschmutzungsempfindlich als eine lineare Lagerung. Um die Regelträgheit der Vorrichtung weiter zu vermindern, kann anstelle der Wälzlagerung eine Magnetlagerung, eine hydraulische Lagerung oder eine Luftlagerung zum Einsatz kommen. Der Schwenkhebel kann, soweit möglich, aus sehr leichtem Material angefertigt sein und dadurch ebenfalls das Massenträgheitsmoment und die Regelträgheit herabsetzen.The as a movable part of the device according to the invention executed swivel lever is by means of a pivot bearing, especially a rolling bearing, and therefore particularly low-friction stored. A pivot bearing can be sealed better and is significantly less sensitive to contamination than a linear one Storage. To further increase the inertia of the device magnetic bearings instead of the roller bearings, a hydraulic bearing or an air bearing are used come. The swivel lever can, as far as possible, be very be made of light material and therefore also that Reduce the moment of inertia and the regular inertia.

Die geschilderten Vorteile führen einzeln oder in Kombination zu einer deutlichen Verbesserung einer gattungsgemäßen Vorrichtung zur Steuerung der Fadenzugkraft. Insbesondere die Regelqualität der Vorrichtung kann erhöht werden.The advantages described lead individually or in combination to a significant improvement of a generic Device for controlling the thread tension. especially the Control quality of the device can be increased.

Als Material dient, soweit möglich, Kunststoff. Der Schwenkhebel 10 trägt auf einem Hebelarm 13 fest mit ihm verbundene Fadenspannelemente 14, 14', 14''. Der Faden 1 verläuft zickzackförmig um die Fadenspannelemente 14, 14', 14'' und die ortsfest am aus Vereinfachungsgründen nicht dargestellten Gehäuse der Steuervorrichtung 4 angeordneten Fadenspannelemente 15, 15', 15'', 15'''. Durch Verschwenken des Schwenkhebels 10 verändern die verstellbaren Fadenspannelemente 14, 14', 14'' und die ortsfesten Fadenspannelemente 15, 15', 15'', 15''' ihre Lage zueinander und damit den Umschlingungswinkel des laufendes Fadens 1 bezüglich der Fadenspannelemente. Mittels dieses die verstellbaren Fadenspannelemente 14, 14', 14'' und die ortsfesten Fadenspannelemente 15, 15', 15'', 15''' umfassenden Rechenspanners 16 läßt sich die auf den Faden 1 wirkende Fadenzugkraft, abhängig vom Umschlingungswinkel, steuern. Auf dem dem Hebelarm 11 diametral gegenüberliegenden Hebelarm 17 ist eine elektrische Spule 18 angeordnet.2 and 3 show a control device 4 in which a Swivel lever 10 can be seen, which is by means of a roller bearing 11 and a shaft 12 is mounted. The pivot lever 10 is off material made as light as possible so that a low Moment of inertia when swiveling and sufficient Strength of the pivot lever 10 is realized. As a material Where possible, plastic is used. The pivot lever 10 carries on a lever arm 13 firmly connected to it Thread tensioning elements 14, 14 ', 14' '. The thread 1 runs zigzag around the thread tensioning elements 14, 14 ', 14' 'and the stationary at not shown for reasons of simplification Housing of the control device 4 arranged Thread tensioning elements 15, 15 ', 15' ', 15' ''. By pivoting the Swivel lever 10 change the adjustable Thread tensioning elements 14, 14 ', 14' 'and the stationary ones Thread tensioning elements 15, 15 ', 15' ', 15' '' their position relative to one another and thus the wrap angle of the running thread 1 regarding the thread tensioning elements. By means of this the adjustable thread tensioning elements 14, 14 ', 14' 'and the stationary thread tensioning elements 15, 15 ', 15' ', 15' '' Computing tensioner 16 can act on the thread 1 Control the thread tension depending on the wrap angle. On the lever arm 17 diametrically opposite the lever arm 11 an electrical coil 18 is arranged.

Die Spule 18 ist zusammen mit dem Hebelarm 17 in einem Luftspalt 49 verschwenkbar, der zwischen dem Joch 19 und den Magneten 20 und 21, die ihrerseits mit dem Joch 22 fest verbunden sind, gebildet ist. Der Luftspalt 49 weist eine gleichbleibende Spaltbreite auf und wird von einem Magnetfeld durchflossen, dessen Magnetfeldlinien durch Pfeile 23 angedeutet sind. Die Joche 19, 22 sind durch die Joche 24, 25, 26 verbunden. Die durch die Joche 19, 22, 24, 25, 26 verlaufenden Feldlinien sind aus Übersichtsgründen nicht dargestellt. Die Magnete 20, 21 sind als Permanentmagnete ausgebildet und unterschiedlich gepolt angeordnet. Die Polausrichtung der Magnete 20, 21 wird durch die Bezeichnung mit S und N angedeutet. Die Bestromung der Spule 18 erfolgt über die Leitungen 27 und 28. Die Leitungen 27 und 28 sind durch Bohrungen 29, 30 in der Welle 12 geführt und sind dadurch nur geringen Bewegungen unterworfen. Mittels gesteuerter Bestromung der Spule 18 wird ein Drehmoment auf den Schwenkhebel 10 aufgebracht, wobei sich durch die Fadenführung auf die Fadenspannelemente 14, 14', 14'' ausgeübten Kräfte ein Kräftegleichgewicht einstellt und eine entsprechende Schwenkposition des Schwenkhebels 10 angesteuert wird.The coil 18 is together with the lever arm 17 in one Air gap 49 pivoted between the yoke 19 and Magnets 20 and 21, which in turn are fixed to the yoke 22 are connected, is formed.

Fig. 4 zeigt ein weiteres Ausführungsbeispiel einer erfindungsgemäßen Steuervorrichtung. Der Schwenkhebel 31 umfaßt zwei fest miteinander verbundene Hebelarme 32, 33. Auf dem Hebelarm 32 sind Fadenspannelemente 34, 34', 34'' angeordnet, die durch Schwenken des Schwenkhebels 31 verstellbar sind. Die Fadenspannelemente 34, 34', 34'' wirken mit den ortsfest am nicht dargestellten Gehäuse positionierten Fadenspannelementen 35, 35', 35'', 35''' als Bestandteile eines Rechenspanners 36. Der als Spulenträger ausgebildete Hebelarm 33 ist gemeinsam mit dem Hebelarm 32 mittels eines Wälzlagers 37 gelagert und um die Achse der Welle 38 schwenkbar. Alternativ können als Lagerung auch Magnetlagerung, Luftlagerung oder andere reibungsarme Lagerungen eingesetzt werden.Fig. 4 shows another embodiment of a control device according to the invention. The pivot lever 31 includes two firmly connected lever arms 32, 33. On the Lever arm 32, thread tensioning elements 34, 34 ', 34' 'are arranged, which are adjustable by pivoting the pivot lever 31. The Thread tensioning elements 34, 34 ', 34' 'act with the stationary on Positioned housing, not shown Thread tensioning elements 35, 35 ', 35' ', 35' '' as components of a Computing tensioner 36. The one designed as a coil carrier Lever arm 33 is together with the lever arm 32 by means of a Rolling bearing 37 is mounted and about the axis of the shaft 38 swiveling. Alternatively, magnetic bearings, Air bearings or other low-friction bearings are used become.

Die elektrische Spule 39 ist auf dem als Spulenträger dienenden Hebelarm 33 so gewickelt, daß ihre Mittelachse die Achse der Welle 38 schneidet. Die Stromzuführung zur Bestromung der Spule 39 kann über die Leitungen 40, 41 in einer der in Fig. 2 dargestellten Stromzuführung entsprechenden Weise erfolgen, wobei die Bewegung, der die Leitungen 40, 41 unterworfen werden, möglichst begrenzt gehalten sein sollte. Ein Innenjoch 42 ist in Form eines Ringsegmentes ausgebildet. Gegenüber dem Außenumfang des Innenjochs 42 sind auf einem ebenfalls ringsegmentartig ausgebildeten Außenjoch 43 Magnete 44, 45 angeordnet.The electrical coil 39 is on the serving as a coil carrier Lever arm 33 wound so that its central axis is the axis of the Wave 38 intersects. The power supply for energizing the Coil 39 can be connected via lines 40, 41 in one of the positions shown in FIG shown power supply take place in a corresponding manner, the movement being subjected to the lines 40, 41 should be kept as limited as possible. On Inner yoke 42 is in the form of a ring segment. Opposite the outer circumference of the inner yoke 42 are on one outer yoke 43 also formed like a ring segment Magnets 44, 45 arranged.

Zwischen dem Innenjoch 42 und den Magneten 44, 45 verbleibt ein Luftspalt 46 mit über seine Länge gleichbleibender Spaltbreite. Die Magnete 44 sind bezüglich der Lage ihrer Pole unterschiedlich zu den Magneten 45 angeordnet. Dadurch bildet sich im Bereich der Magnete 44 ein Magnetfeld, dessen Magnetfeldlinien 47 im wesentlichen auf den Drehpunkt des Schwenkhebels 32 ausgerichtet sind, während die Magnetfeldlinien 48 im Bereich der Magnete 45 in entgegengesetzter Richtung verlaufen. Feldlinien sind aus Übersichtsgründen nur im Bereich des Luftspaltes 46 und nicht zusätzlich im Innenjoch 42 und im Außenjoch 43 dargestellt. Auch bei diesem alternativen Ausführungsbeispiel wird mittels gesteuerter Bestromung der Spule 39 ein Drehmoment auf den Schwenkhebel 31 aufgebracht und eine entsprechende Schwenkposition des Schwenkhebels 10 angesteuert. An der Anordnung des Luftspaltes 46 und der zugehörigen elektrischen Spule 39 ist vorteilhaft, daß die zur Erzeugung des Drehmomentes erforderlichen und im Luftspalt verlaufenden Windungsstränge 39', 39'' der elektrischen Spule 39 vollständig in relativ großem Abstand zur Drehachse des Schwenkhebels 31 angeordnet sind, so daß aufgrund der Hebelwirkung ein relativ hohes Moment erzeugt werden kann. Durch das Zusammenwirken der jeweiligen Feldlinienrichtung und der Stromrichtung in den Windungssträngen 39', 39'' der elektrischen Spule 39 sind über den gesamten relevanten Schwenkbereich des Schwenkhebels 31 Strom und Moment proportional. Der Steuer- beziehungweise Regelungsaufwand kann dadurch gering gehalten werden. Die verstellbaren Fadenspannelemente 34, 34', 34'' üben zusammen mit den ortsfesten Fadenspannelementen 35, 35', 35'', 35''' eine die Fadenspannung steuernde Bremswirkung aus.A remains between the inner yoke 42 and the magnets 44, 45 Air gap 46 with a constant gap width over its length.
