Description

Die Erfindung betrifft eine Wickelvorrichtung zur Erzeugung eines Wattenwickels, bei der die Watte auf einen von einem umlaufenden, endlosen Riemen angetriebenen Kern aufgewickelt wird, der um eine feste Achse drehbar in einer zwischen zwei Umlenkrollen gebildeten, mit zunehmendem Wattenwickel größer werdenden Schleife des durch eine Spanneinrichtung gespannten Riemens angeordnet ist.The invention relates to a winding device for generating a Wadding wrap, in which the wadding on one of a circumferential, endless belt driven core is wound up which rotates around a fixed axis in one between two pulleys formed, increasing with increasing wadding Loop of the belt tensioned by a tensioning device is arranged.

Bei einer aus der GB 329 871 bekannten Wickelvorrichtung dieser Art liegt der Riemen zu Beginn des Wickelvorgangs lediglich an einem geringen Teil des Kernumfangs an. Der Umschlingungswinkel beträgt weniger als 60°. Das Spannen des Riemens erfolgt über einen Winkelhebel, an dessen einem Arm eine vom Riemen umschlungene Umlenkrolle und an dessen anderem Arm ein Gewicht angeordnet ist, das zur Einstellung der Spannkraft manuell verstellbar ist.In a winding device known from GB 329 871 Art is just the belt at the beginning of the winding process a small part of the core scope. The wrap angle is less than 60 °. The belt is tensioned via an angle lever, on one arm a belt-wrapped one Pulley and a weight on its other arm is arranged, which is manually adjustable to adjust the clamping force is.

Bei dieser bekannten Wickelvorrichtung kann aufgrund der lokalen Belastung des Wattenwickels eine Art Walkeffekt auftreten, der zur Folge hat, daß verschiedene Wickellagen gegeneinander verschoben werden. Infolge der Reibung kann es hierbei zu einem Verfilzen der Watte kommen, was Probleme beim Abwicklen des Wickels mit sich bringt und zu Qualitätseinbußen führen kann.In this known winding device due to the local A kind of whale effect occurs which has the result that different winding layers against each other be moved. Due to the friction, this can lead to a Matting of the cotton wool come up, causing problems when unwinding the Brings with it and can lead to loss of quality.

Aus der GB-PS 680,464 ist eine weitere Vorrichtung zur Wickelbildung mittels eines Riemens bekannt. Hierbei liegt die Hülse, auf welche die Watte aufgewickelt wird, lose in der Riemenschlaufe. Dadurch entfernt sich die Hülse bei grösser werdendem Wickeldurchmesser von den Zuführwalzen. Bei dieser Vorrichtung ist einerseits das exakte Aufeinanderlegen der einzelnen Wattebahnen nicht gewährleistet und andererseits ist die Einleitung einer dem jeweiligen Wickeldurchmesser angepassten Druckkraft während der Wickelbildung nicht möglich.From GB-PS 680,464 is another device for winding formation known by means of a belt. Here is the sleeve, on which the cotton is wound up, loosely in the belt loop. This removes the sleeve as it grows Winding diameter from the feed rollers. With this device is on the one hand the exact stacking of the individual Cotton webs are not guaranteed and on the other hand is Initiation of an adapted to the respective winding diameter Compressive force not possible during the formation of the wrap.

Ziel der Erfindung ist es, eine Wickelvorrichtung der eingangs genannten Art zu schaffen, die bei einfachem Aufbau die Herstellung qualitativ hochwertiger, problemlos abwickelbarer Wattenwickel ermöglicht.The aim of the invention is to provide a winding device at the beginning to create the type mentioned, the manufacture with a simple structure high quality, easily unwrapped wadding allows.

Die Aufgabe wird nach der Erfindung dadurch gelöst, daß der um eine feste Achse drehbare Kern und die beiden Umlenkrollen derart bemessen und relativ zueinander angeordnet sind, daß die Schleife zu Beginn des Wickelvorgangs den Kern mit einem anfänglichen minimalen Umschlingungswinkel umgibt, der gleich oder größer als 120° und vorzugsweise gleich oder größer als 180 ° ist, und daß die Spanneinrichtung zur Erzeugung einer vom Wickeldurchmesser abhängigen Spannkraft mit einer Steuereinrichtung gekoppelt ist.The object is achieved according to the invention in that the order a fixed axis rotatable core and the two pulleys dimensioned and arranged relative to each other, that the loop with the core at the beginning of the winding process surrounding an initial minimum wrap angle, which is equal to or greater than 120 ° and preferably the same or greater than 180 °, and that the clamping device for Generation of a tension force dependent on the winding diameter is coupled to a control device.

Nachdem der um eine feste Achse drehbare Kern bereits zu Beginn des Wickelvorgangs über einen großen Bereich, d.h. mit einem größeren Umschlingungswinkel vom Riemen umgeben ist, wird der entstehende Wattenwickel von vornherein wesentlich gleichmäßiger belastet. Zudem kann einer möglichen Eibildung während des Wickelaufbaus auf wirksame Weise durch eine entsprechende Anpassung der Spannkraft an den jeweiligen Wickeldurchmesser entgegengewirkt werden. Trotz der feststehenden Achse des Kerns kann das Auftreten eines Walkeffekts praktisch ausgeschlossen werden. Damit wird auch vermieden, daß verschiedene Wattenlagen gegeneinander verschoben werden und die Watte verfilzt. Im Ergebnis wird ein qualitativ hochwertiger Wickel erzeugt, der für eine weitere Verarbeitung der Watte problemlos abwickelbar ist.After the core can be rotated about a fixed axis Start of wrapping over a large area, i.e. surrounded by the belt with a larger wrap angle is, the resulting wadding becomes essential from the start more evenly loaded. In addition, one can Egg formation during the build-up of the wrap effectively by adjusting the clamping force accordingly respective winding diameters can be counteracted. Despite the fixed axis of the nucleus can occur Walk effect can be practically excluded. So that will also avoided that different layers of cotton wool against each other be moved and the cotton wool matted. As a result produces a high quality wrap that is suitable for a further processing of the cotton wool can be easily handled.

Insbesondere im Hinblick auf eine möglichst geringe Blasenbildung und ein weiter verbessertes Abwickelverhalten ist es von Vorteil, wenn die Spanneinrichtung so durch die Steuereinrichtung beaufschlagt ist, daß die Spannkraft bis zum Erreichen einer vorgebbaren Wickelgröße mit zunehmendem Wickeldurchmesser abnimmt. Hierbei nimmt die Spannkraft bis zum Erreichen der vorgebbaren Wickelgröße mit dem zunehmenden Wickeldurchmesser vorzugsweise linear ab. Durch das anfänglich härtere Wickeln mit höherer Kraft wird die Plastizität des Wickels reduziert, und der Wickel wird in sich stabiler, was sich positiv sowohl auf das Abwickelverhalten als auch auf die Qualität auswirkt. Especially with regard to the lowest possible blistering and is a further improved unwinding behavior it is advantageous if the clamping device through the Control device is loaded that the clamping force up to achieve a predefinable winding size with increasing Winding diameter decreases. Here the tension increases to achieve the predefinable winding size with increasing Winding diameter preferably linear. Through that initially harder wrapping with higher force becomes plasticity of the wrap is reduced, and the wrap becomes in itself more stable, which positively affects both the unwinding behavior as well as the quality.

Von Vorteil ist ferner, wenn die vorgebbare Wickelgröße kleiner als die endgültige Wickelgröße gewählt und die Spannkraft ab der vorgebbaren Wickelgröße bis zum Erreichen der endgültigen Wickelgröße konstant gehalten ist. Dabei ist vorzugsweise vorgesehen, die Spannkraft während des überwiegenden Teils des Wickelvorgangs mit zunehmendem Wikkeldurchmesser zu reduzieren und erst zum Ende des Wickelvorgangs hin bis zum erreichen der endgültigen Wickelgröße auf einem Wert ungleich Null konstant zu halten.It is also advantageous if the predeterminable winding size chosen smaller than the final wrap size and the Tension from the predeterminable winding size until it is reached the final winding size is kept constant. there is preferably provided, the clamping force during the predominant part of the winding process with increasing winding diameter to reduce and only at the end of the winding process until the final winding size is reached to keep constant at a non-zero value.

Die Steuereinrichtung, bei der es sich vorteilhafterweise um eine elektronische Steuereinrichtung handelt, kann mit einem Sensor gekoppelt sein, der unmittelbar den Wickeldurchmesser erfaßt. Grundsätzlich ist es jedoch auch denkbar, eine die einlaufende Wattenlänge erfassende Meßeinrichtung vorzusehen, um der Steuereinrichtung ein für den Wickeldurchmesser repräsentatives Signal zu liefern.The control device, which is advantageously is an electronic control device can with be coupled to a sensor that directly the winding diameter detected. In principle, however, it is also conceivable a measuring device that detects the incoming length of wadding to provide the control device for the To deliver a winding signal representative signal.

Bei einer praktisch bevorzugten Ausführungsvariante umfaßt die Spanneinrichtung eine Spannrolle mit zugeordneter Linearführung. Hierbei wird der Riemen zweckmäßigerweise in einer Ebene gespannt, die parallel zu der Ebene ist, die die Achsen der beiden zwischen sich die Schleife bildenden Umlenkrolle enthält. Insbesondere im Hinblick auf eine möglichst präzise Steuerung der Spannkraft ist es auch von Vorteil, wenn der Riemen die Spannrolle unabhängig von deren Stellung stets mit einem Umschlingungswinkel von 180° umgibt. In diesem Fall verlaufen die beiden einander gegenüberliegenden Riemenabschnitte im Bereich der Spannrolle stets parallel zueinander, wodurch u.a. eine präzisere Steuerung der Spannkraft ermöglicht wird. Die Verstellung der Spannrolle kann über einen mit der Steuereinrichtung gekoppelten elektrischen, hydraulischen oder pneumatischen Antrieb erfolgen, wobei dieser Antrieb zweckmäßigerweise eine Zylinder/Kolben-Einheit umfassen kann.In a practically preferred embodiment variant comprises the tensioning device has a tensioning pulley with an associated linear guide. Here, the belt is conveniently in one Plane that is parallel to the plane that is the Axes of the two deflection rollers forming the loop between them contains. Especially with a view to a possible it is also from precise control of the clamping force Advantage if the belt is independent of the tension pulley Always with a wrap angle of 180 ° surrounds. In this case, the two are opposite each other Belt sections in the area of the tension pulley always parallel to each other, which means that a more precise Control of the clamping force is made possible. The adjustment the tension pulley can be connected to the control device coupled electrical, hydraulic or pneumatic Drive take place, this drive expediently can comprise a cylinder / piston unit.

Der Riemen ist zweckmäßigerweise über wenigstens eine der Umlenkrollen angetrieben. Zur Steuerung oder Regelung der Riemenantriebsgeschwindigkeit kann auch der Riemenantrieb mit der Steuereinrichtung gekoppelt sein. Die Riemenantriebsgeschwindigkeit kann mit dem Wickeldurchmesser variieren und beispielsweise mit zunehmendem Wickeldurchmesser abnehmen. Die Steuerung oder Regelung kann so vorgesehen sein, daß die Riemenantriebsgeschwindigkeit zu Beginn eines jeden Wickelvorgangs von Null auf einen vorgegebenen Wert erhöht wird. Der Riemenantrieb kann über einen Umrichter oder dergleichen frequenzgesteuert sein. Es ist auch denkbar, die Riemenantriebsgeschwindigkeit zumindest zeitweise konstant zu halten.The belt is advantageously over at least one of the Deflection pulleys driven. To control or regulate the Belt drive speed can also be the belt drive be coupled to the control device. The belt drive speed can vary with the winding diameter and for example with increasing winding diameter lose weight. The control or regulation can be provided in this way be that the belt drive speed at the beginning of a every winding process from zero to a predetermined value is increased. The belt drive can be via a converter or the like to be frequency controlled. It is also conceivable the belt drive speed at least temporarily to keep constant.

Ist der Kern durch eine Hülse gebildet, so kann diese beispielsweise auf Ansätzen zweier einander gegenüberliegender Wickelscheiben aufgesetzt sein, zwischen denen sie vorzugsweise eingespannt wird.If the core is formed by a sleeve, this can, for example on approaches of two opposite one another Winding disks are placed between which they are preferably is clamped.

Die beiden zwischen sich die Schleife bildenden Umlenkrollen sind zum Auswerfen des Wattenwickels durch gleichzeitiges Spannen des Riemens vorzugsweise relativ voneinander entfernbar.The two pulleys that form the loop are for ejecting the wadding by simultaneous Tensioning the belt preferably relative to each other removable.

Gemäß einer besonders vorteilhaften Ausführungsvariante der Erfindung ist das beispielsweise durch Ausfahren, Verschwenken und/oder dergleichen erfolgende Entfernen wenigstens einer der Wickelscheiben, das Auswerfen des Wattenwickels, das Abführen des Wattenwickels zu einer Transporteinrichtung oder dergleichen und/oder das Einführen und Einspannen einer neuen Hülse zumindest teilweise automatisiert und wiederum durch die Steuereinrichtung gesteuert. According to a particularly advantageous embodiment variant of the The invention is for example by extending, pivoting and / or removal at least one of the winding disks, ejecting the wadding roll, the removal of the wadding roll to a transport device or the like and / or the insertion and Clamping a new sleeve at least partially automated and again controlled by the control device.

Figur 1 zeigt in rein schematischer Darstellung eine Wikkelvorrichtung 10 zur Erzeugung eines Wattenwickels 12. Grundsätzlich kann eine solche Wickelvorrichtung 10 dazu dienen, ein Vlies, einen Flor oder Watte aus Fasermaterial zu einem Wickel aufzurollen, bevor das Fasermaterial einer weiteren Behandlung unterzogen wird. So kann die Wickelvorrichtung beispielsweise in einer Kämmerei zur Aufnahme eines aus einem Streckwerk auslaufenden, über Kehrbleche, Kalanderwalzen und/oder dergleichen zugeführten Vlieses dienen, wobei der erzeugte Wickel anschließend einer Kämmaschine vorgelegt wird. Im folgenden ist im Zusammenhang mit dem zugeführten Fasermaterial der Einfachheit halber lediglich von Watte die Rede, was nicht in einschränkendem Sinne zu verstehen ist.FIG. 1 shows a winding device in a purely schematic representation 10 for producing a wadding roll 12. In principle, such a winding device 10 can do this serve a fleece, a pile or cotton wool made of fiber material to roll up into a wrap before the fiber material one undergoes further treatment. So can the winding device for example in a combing room for receiving a out of a drafting system, over dustpan and calender rollers and / or the like supplied fleece, the generated winder then a combing machine is presented. The following is related to the supplied fiber material for the sake of simplicity of cotton wool, which is not restrictive is to be understood.

Der Wickelvorrichtung 10 wird Watte 14 über eine Wattezuführung 16 zugeführt, die im vorliegenden Fall durch ein am auslaufseitigen Ende gebogenes Blech gebildet ist.The winding device 10 becomes cotton 14 via a cotton feed 16 supplied, which in the present case by an am outlet-side end of bent sheet metal is formed.

Die Watte 14 wird auf eine als Kern dienende Hülse H aufgewickelt, die um eine feste Achse A drehbar gelagert ist. Diese Hülse H wird von einem umlaufenden, endlosen Riemen 18 angetrieben, durch den zwischen zwei Umlenkrollen R1 und R2 eine Schleife 20 gebildet wird, in der die Hülse H aufgenommen ist. The cotton wool 14 is wound on a core H serving as a core, which is rotatably mounted about a fixed axis A. This sleeve H is made of a continuous, endless belt 18 driven by the between two pulleys R1 and R2 a loop 20 is formed in which the sleeve H is received is.

Im vorliegenden Fall wird der Wattenwickel 12 durch den Riemen 18 entgegen dem Uhrzeigersinn angetrieben, wie dies durch den Pfeil F angedeutet ist. Die den Wattenwickel 12 umschlingende Schleife 20 des Riemens 18 wird mit zunehmendem Wattenwickel 12 größer, wobei der Riemen 18 während des gesamten Wickelvorgangs durch eine Spanneinrichtung 22 gespannt wird. Diese Spanneinrichtung 22 umfaßt eine Spannrolle R4 mit zugeordneter Linearführung 24.In the present case, the wadding 12 is by the Belt 18 driven counterclockwise like this is indicated by the arrow F. The cotton wadding 12 looping loop 20 of the belt 18 is increasing Cotton wrap 12 larger, the belt 18 during the Entire winding process stretched by a tensioning device 22 becomes. This tensioning device 22 includes a Tensioner pulley R4 with assigned linear guide 24.

Der Riemen 18 ist über weitere Umlenkrollen R3 und R5 und die entlang der Linearführung 24 verstellbare Spannrolle R4 so geführt, daß er über die Spannrolle R4 in einer Ebene gespannt wird, die parallel zu der die Achsen der beiden Umlenkrollen R1 und R2 enthaltenden Ebene ist. In Figur 1 ist die Achse, entlang der die Spannrolle R4 verstellbar ist, als X-Achse bezeichnet.The belt 18 is on further pulleys R3 and R5 and the tension roller R4 adjustable along the linear guide 24 guided so that it over the tension roller R4 in one plane is stretched parallel to the axis of the two Deflecting rollers containing R1 and R2 level. In Figure 1 is the axis along which the tension pulley R4 is adjustable is referred to as the X axis.

Beim in Figur 1 dargestellten Ausführungsbeispiel weisen die Umlenkrollen R1, R2, R3 und R5, die Spannrolle R4 und die Hülse H einen gleichen Durchmesser auf. Die Achsen der Rollen sowie der Hülse sind zueinander parallel. Die oben gelegenen Umlenkrollen R1 und R2 weisen einen vertikalen Abstand zu der weiteren Umlenkrolle R5 und der Spannrolle R4 auf, der größer als der maximale Durchmesser des Wattenwickels 12 ist.Point in the embodiment shown in Figure 1 the pulleys R1, R2, R3 and R5, the tension pulley R4 and the sleeve H has the same diameter. The axes of the Rollers and the sleeve are parallel to each other. The above located pulleys R1 and R2 have a vertical Distance to the other pulley R5 and the tension pulley R4 which is larger than the maximum diameter of the wadding roll 12 is.

Die beiden Umlenkrollen R1 und R2 einerseits sowie die Umlenkrolle R5 und die Spannrolle R4 andererseits liegen mit ihren Achsen jeweils in einer Horizontalebene. In der mit durchgezogenen Linien dargestellten Position der Rollen, die sich am Ende des Wickelvorgangs mit ihre linke Endposition einnehmender Spannrolle R4 und noch nicht nach außen verschwenkter Umlenkrolle R2 ergibt (die Umlenkrollen R1, R3 und R5 sind stationär), ist die untere linke Umlenkrolle R5 gegenüber der oberen linken Umlenkrolle R2 nach links versetzt. Die Spannrolle R4 ist in ihrer in Figur 1 mit durchgezogenen Linien dargestellten linken Endposition am Ende des Wickelvorgangs gegenüber der oberen Umlenkrolle R1 nach rechts versetzt, wobei der horizontale Abstand zwischen diesen Rollen R1 und R4 größer als der zwischen den Rollen R2 und R5 ist. Damit sind die Rollen R1, R2, R4 und R5 trapezförmig angeordnet, wobei der horizontale Abstand zwischen den Rollen R4 und R5 größer als der zwischen den Rollen R1 und R2 ist.The two pulleys R1 and R2 on the one hand and the pulley R5 and the idler pulley R4 on the other hand are with their axes each in a horizontal plane. In the with position of the rollers represented by solid lines, which at the end of the winding process with their left end position captive tensioner R4 and not yet to the outside pivoted deflection roller R2 results (the deflection rollers R1, R3 and R5 are stationary), is the lower left pulley R5 to the left opposite the upper left pulley R2 added. The tensioning pulley R4 is shown in FIG solid left end position shown on End of the winding process in relation to the upper deflection roller R1 offset to the right, with the horizontal distance between these roles R1 and R4 larger than that between the Roles R2 and R5 is. So the roles are R1, R2, R4 and R5 arranged trapezoidal, with the horizontal distance between the rollers R4 and R5 larger than that between the Roles R1 and R2 is.

In dieser in Figur 1 mit durchgezogenen Linien dargestellten Rollenposition nimmt die Spannrolle R4 ihre linke Endposition ein. Ausgehend von dieser linken Endposition der Spannrolle R4 ist die darüber angeordnete weitere Umlenkrolle R3 um einen Betrag nach links versetzt, der von Rollenmitte zu Rollenmitte gemessen etwa gleich dem Radius der einen gleichen Durchmesser besitzenden Rollen R1 bis R5 entspricht. Der vertikale Abstand zwischen den Rollen R3 und R4 entspricht von Mitte zu Mitte gemessen etwa dem Rollendurchmesser. Damit ist sichergestellt, daß der Riemen 18 die Spannrolle R4 unabhängig von deren Stellung stets mit einem Umschlingungswinkel von 180° umgibt.Shown in this in Figure 1 with solid lines The roller position R4 takes its left end position on. Starting from this left end position of the Tensioner pulley R4 is the additional deflection pulley arranged above R3 shifted to the left by an amount from Roll center to roll center measured approximately equal to the radius the same diameter rollers R1 to R5 equivalent. The vertical distance between the rollers R3 and R4 is about the same from center to center Roll diameter. This ensures that the belt 18 the tension pulley R4 regardless of their position always surrounds with a wrap angle of 180 °.

Der Riemen 18 wird beispielsweise über die linke untere Umlenkrolle R5 angetrieben, die in der Ebene liegt, in der der Riemen 18 gespannt wird.The belt 18 is for example on the lower left pulley R5 driven, which lies in the plane in which the belt 18 is tensioned.

Die linke obere Umlenkrolle R2 ist am oberen Ende eines Schwenkhebels 26 angebracht, der am anderen Ende um die Achse der linken unteren Umlenkrolle R5 schwenkbar gelagert ist. In Figur 1 ist mit strichpunktierten Linien die nach links ausgeschwenkte Position des Schwenkhebels 26 dargestellt, in der der volle Wattenwickel 12 ausgeworfen wird. The left upper pulley R2 is at the top of one Swivel lever 26 attached to the other end around the The axis of the lower left pulley R5 is pivoted is. In Figure 1 is the dashed lines position of the pivot lever 26 swiveled out to the left, in which the full wadding 12 is ejected.

Die um die feste Achse A drehbare Hülse H und die beiden Umlenkrollen R1 und R2 sind derart bemessen und bei in die Arbeitsposition nach rechts verschwenktem Schwenkarm 26 so relativ zueinander angeordnet, daß die durch den Riemen 18 zwischen den Umlenkrollen R1 und R2 gebildete Schleife 20 die Hülse H zu Beginn des Wickelvorgangs mit einem anfänglichen minimalen Umschlingungswinkel umgibt, der vorzugsweise gleich groß oder größer als 120° und insbesondere gleich oder größer als 180°, im vorliegenden Fall etwa 180° ist. Dieser Verlauf der Schleife 20 am Anfang des Wickelvorgangs ist in Figur 1 durch punktierte Linien dargestellt. In dieser Phase nimmt die Spannrolle R4 ihre rechte Endposition ein. Während des Wickelvorgangs wird der Umschlingungswinkel, mit dem die Schleife 20 die Hülse H umgibt, größer. Die Spannrolle R4 wird nach links verlagert, bis sie nach vollendetem Wattenwickel 12 die mit durchgezogenen Linien dargestellte linke Endposition erreicht hat.The sleeve H rotatable about the fixed axis A and the two Deflection pulleys R1 and R2 are dimensioned in this way and in Working position pivoted to the right swivel arm 26 so arranged relative to each other that the belt 18 Loop 20 formed between the pulleys R1 and R2 the sleeve H at the beginning of the winding process with an initial minimum wrap angle that preferably surrounds the same size or greater than 120 ° and in particular equal to or greater than 180 °, in the present case approximately 180 ° is. This course of the loop 20 at the beginning of the winding process is shown in Figure 1 by dotted lines. In this phase the tension pulley R4 takes its right End position. During the winding process, the wrap angle, with which the loop 20 surrounds the sleeve H, greater. The tension pulley R4 is shifted to the left, until after the finished cotton wadding 12 the with solid Left end position shown in lines has reached.

Die beiden oberen Umlenkrollen R1 und R2 sind zur Einstellung der Wickelvorrichtung vor der Inbetriebnahme in allen Richtungen einstellbar. Die Umlenkrolle R3 ist bombiert und in seitlichen Richtungen einstellbar. Die als Antriebsrolle dienende Umlenkrolle R5 ist nicht bombiert und nicht einstellbar. Der Antrieb kann insbesondere über eine Kupplung und ein Reduktionsgetriebe erfolgen. Der zugeordnete Motor kann frequenzgesteuert sein.The two upper pulleys R1 and R2 are for adjustment of the winding device before commissioning in all Directions adjustable. The pulley R3 is cambered and adjustable in lateral directions. That as a driving role serving pulley R5 is not cambered and not adjustable. The drive can in particular be via a clutch and a reduction gear take place. The assigned engine can be frequency controlled.

Die Spanneinrichtung 22 ist zur Erzeugung einer vom Wickeldurchmesser abhängigen Spannkraft mit einer vorzugsweise elektronischen Steuereinrichtung 28 gekoppelt. Beim in Figur 1 dargestellten Ausführungsbeispiel ist ein unmittelbar den Wickeldurchmesser erfassender Sensor 30 vorgesehen, der der Steuereinrichtung 28 ein entsprechendes Signal S1 liefert. Statt dessen ist jedoch auch denkbar, eine mit der Steuereinrichtung 28 gekoppelte Meßeinrichtung zu verwenden, die die einlaufende Wattenlänge erfaßt, um der Steuereinrichtung 28 ein für den Wickeldurchmesser repräsentatives Signal zu liefern.The tensioning device 22 is used to generate a winding diameter dependent clamping force with a preferably electronic control device 28 coupled. When in figure 1 is an immediate embodiment the winding diameter detecting sensor 30 is provided, the the control device 28 supplies a corresponding signal S1. Instead, however, it is also conceivable to use one with the Control device 28 to use coupled measuring device, which detects the incoming lap length to the control device 28 a representative of the winding diameter Deliver signal.

Die über die Steuereinrichtung 28 gesteuerte Verstellung der Spannrolle R4 entlang der Linearführung 24 kann beispielsweise über einen elektrischen, hydraulischen oder pneumatischen Antrieb erfolgen. Dieser Antrieb kann beispielsweise eine Zylinder/Kolben-Einheit umfassen.The adjustment controlled by the control device 28 the tension roller R4 along the linear guide 24 can for example via an electrical, hydraulic or pneumatic drive. This drive can, for example comprise a cylinder / piston unit.

Auch der beispielsweise über die Umlenkrolle R5 erfolgende Riemenantrieb kann über die Steuereinrichtung 28 gesteuert und/oder geregelt sein, was beispielsweise über einen frequenzgesteuerten Umrichter oder dergleichen möglich ist.Also the one that takes place, for example, via the deflection roller R5 Belt drive can be controlled via the control device 28 and / or be regulated, for example via a frequency-controlled Converter or the like is possible.

Hierbei haben sich die Umschlingungswinkel w3, w4 und w5 im Bereich der Umlenkrolle R3, der Spannrolle R4 und der Umlenkrolle R5 gegenüber der Phase zu Beginn des Wickelvorgangs nicht geändert.FIG. 5 shows a simplified illustration comparable to FIG. 4 the winding device, but this in the Phase is shown at the end of the winding process, i.e. the Tensioner pulley R4 assumes its left end position. Have here the wrap angles w3, w4 and w5 in the range the pulley R3, the tension pulley R4 and the pulley R5 not compared to the phase at the beginning of the winding process changed.

    Dagegen beträgt der Umschlingungswinkel wH', mit dem die Schleife 20 die Hülse H umgibt, nunmehr etwa 282°.In contrast, the wrap angle wH 'with which the Loop 20 surrounds the sleeve H, now about 282 °.

Die Länge L16 des freiliegenden Riemenabschnitts zwischen der Spannrolle R4 und der Umlenkrolle R5 beträgt 1.010 mm. Die Längen L11 und L13 der freiliegenden Riemenabschnitte zwischen den Umlenkrollen R2 und R5 bzw. zwischen den Umlenkrollen R1 und R3 bleiben unverändert.The wrap angle w1 'in the region of the deflection roller R1 is now about 215 °. In the area of the role R2 is the wrap angle w2 'is now approximately 211 °. The length L9 the exposed belt section between the pulley R3 and the tension roller R4 is 100 mm. So it corresponds the radius of these two roles, which is equal to the radius the remaining pulleys and the sleeve H is. The length L16 of the exposed belt section between the Tensioner pulley R4 and the deflection pulley R5 is 1,010 mm. The Lengths L11 and L13 of the exposed belt sections between the pulleys R2 and R5 or between the pulleys R1 and R3 remain unchanged.

The winding disks can now can be removed as indicated by the horizontal arrow is shown.

    Bei dem zuvor beschriebenen Ausführungsbeispiel betrug die Riemenlänge 5720 mm. Als Riemen 18 kann beispielsweise ein aus Aramid wie insbesondere Kevlar endlos gewickelter Riemen oder beispielsweise ein mit Stoß versehener Riemen aus Polyamid oder dergleichen verwendet werden.In the exemplary embodiment described above, the Belt length 5720 mm. A belt 18 can be, for example made of aramid like especially Kevlar endlessly wound straps or, for example, a strapped strap Polyamide or the like can be used.

    Bei der bevorzugten Ausführungsvariante ist die Spanneinrichtung 24 derart durch die Steuereinrichtung 28 beaufschlagt, daß die Spannkraft bis zum Erreichen einer vorgebbaren Wickelgröße mit zunehmendem Wickeldurchmesser abnimmt. Diese Abnahme der Spannkraft erfolgt vorzugsweise linear, wie sich dies aus Figur 7 ergibt, in der die Spannkraft über dem Wickeldurchmesser dargestellt ist. Aus dieser Figur 7 ergibt sich auch, daß beim bevorzugten Ausführungsbeispiel die Spannkraft ab der vorgebbaren Wickelgröße, die im vorliegenden Fall bei etwa 560 mm liegt, bis zum Erreichen der endgültigen Wickelgröße konstant gehalten ist. In the preferred embodiment variant, the tensioning device is 24 acted upon by the control device 28 in this way, that the clamping force until a predefinable The winding size decreases with increasing winding diameter. This decrease in the clamping force is preferably carried out linear, as can be seen from Figure 7, in which the clamping force is shown above the winding diameter. From this Figure 7 also shows that in the preferred embodiment the tension force from the predeterminable winding size, which in the present case is approximately 560 mm, up to Reaching the final winding size kept constant is.

    Gemäß Figur 7 beträgt die anfängliche Spannkraft zu Beginn des Wickelvorgangs etwa 24000 N bei einem anfänglichen Wikkeldurchmesser von 200 mm. Diese Spannkraft nimmt dann linear bis auf etwa 10000 N bei einem Wickeldurchmesser von etwa 560 mm ab. Anschließend wird die Spannkraft bis zum Erreichen der endgültigen Wickelgröße konstant gehalten.According to FIG. 7, the initial tension is at the beginning of the winding process about 24000 N at an initial winding diameter of 200 mm. This tension then increases linearly up to about 10000 N with a winding diameter of about 560 mm. Then the clamping force is up to Reaching the final winding size kept constant.

    Hiermit wird sowohl die Blasenbildung minimiert als auch das Abwickelverhalten verbessert. Durch das anfänglich härtere Wickeln mit höherer Kraft wird die Plastizität des Wickels reduziert, und der Wickel wird in sich stabiler, was sich positiv sowohl auf das Abwickelverhalten als auch auf die Qualität auswirkt.This minimizes blistering as well improves the unwinding behavior. By the initially harder Winding with higher force will increase the plasticity of the Winding is reduced, and the winding becomes more stable in itself, which positively affects both the unwinding behavior as well affects the quality.

    Wie anhand von Figur 5 zu erkennen ist, liegt der fertige Wattenwickel 12 innerhalb des durch die Führungsrollen R1 bis R3 und R5 sowie die Spannrolle R4 definierten Bereichs. Nachdem die Wickelscheiben 32, 34 zur Freigabe des Wickels entfernt, beispielsweise verschoben, ausgefahren, verschwenkt und/oder dergleichen, sind, muß die Umlenkrolle R2 über den Schwenkhebel 26 in die in Figur 1 mit strichpunktierten Linien dargestellte Position nach außen verschwenkt werden, damit der Wickel ausgeworfen werden kann. Dieses Auswerfen erfolgt dadurch, daß mit dem Verschwenken des Schwenkhebels 26 gleichzeitig der Riemen 18 gespannt wird. Nachdem die beiden oberen Führungsrollen R1 und R2 nunmehr voneinander entfernt werden, kann der Wattenwickel 12 ungehindert nach oben abgeführt werden.As can be seen from Figure 5, the finished Cotton wadding 12 inside by the guide rollers R1 to R3 and R5 and the tension roller R4 defined range. After the winding disks 32, 34 to release the winding removed, for example moved, extended, pivoted and / or the like, the guide roller R2 via the pivot lever 26 in the dash-dotted in Figure 1 Lines shown position pivoted outwards so that the wrap can be ejected. This Ejection takes place in that with the pivoting of the Swing lever 26 at the same time the belt 18 is tensioned. After the two upper guide rollers R1 and R2 now are separated from each other, the wadding roll 12 can be freely can be discharged upwards.

    Grundsätzlich ist jedoch auch eine andere Anordnung der Rollen möglich, bei der der Wickel nicht nach oben, sondern bezüglich der Darstellung in Figur 1 z. B. nach links oder nach rechts abgeführt wird. Dazu ist die in Figur 1 gezeigte Anordnung in der Zeichnungsebene um 90° zu drehen. Grundsätzlich ist es jedoch auch denkbar, den Wickel nach unten abzuführen.In principle, however, another arrangement of the Rolls possible where the wrap is not up, but with respect to the representation in Figure 1 z. B. to the left or is discharged to the right. This is shown in Figure 1 Rotate the arrangement in the drawing plane by 90 °. In principle, however, it is also conceivable to follow the winding dissipate below.

    Gemäß Figur 1 wird die Watte 14 über die Wattenzuführung 16 von der linken Seite her in den Bereich 42 zwischen dem Riemen 18 und der Hülse H eingeführt, also auf der der Linearführung 24 gegenüberliegenden Seite. Grundsätzlich ist es jedoch auch denkbar, die Watte 14 auf der gleichen Seite zuzuführen, auf der die Linearführung 24 der Spanneinrichtung 22 angeordnet ist. In diesem Fall wäre jedoch die Drehrichtung des Riemenantriebs umzukehren, damit die Watte in den Spalt zwischen Riemen 18 und Hülse H eingezogen wird.According to FIG. 1, the cotton wool 14 is fed over the cotton wool feeder 16 from the left into the area 42 between the Belt 18 and the sleeve H inserted, so on the linear guide 24 opposite side. Basically is however, it is also conceivable to have the cotton wool 14 on the same side feed on the linear guide 24 of the clamping device 22 is arranged. In this case, however, that would be Reverse the direction of rotation of the belt drive so the cotton wool drawn into the gap between belt 18 and sleeve H. becomes.

    In Figur 1 ist durch das Steuersignal S2 angedeutet, daß die Spanneinrichtung 22 zum Steuern und/oder Regeln der Spannkraft in Abhängigkeit vom Wickeldurchmesser von der Steuereinrichtung 28 beaufschlagt ist. Über diese Steuereinrichtung 28 ist vorzugsweise auch die Riemenantriebsgeschwindigkeit steuer- bzw. regelbar. Auch diese Riemenantriebsgeschwindigkeit kann wiederum in Abhängigkeit vom Wickeldurchmesser variabel sein. Zu Beginn eines jeweiligen Wickelvorgangs kann vorgesehen sein, die Antriebsgeschwindigkeit vorzugsweise relativ rasch von Null auf einen vorgegebenen Wert zu erhöhen. Der vorzugsweise über die Umlenkrolle R5 erfolgende Riemenantrieb kann zudem so gesteuert sein, daß die Riemenantriebsgeschwindigkeit während des Wickelvorgangs zumindest zeitweise mit zunehmendem Wickeldurchmesser abnimmt. Grundsätzlich ist jedoch auch ein Riemenantrieb mit zumindest zeitweise konstanter Riemenantriebsgeschwindigkeit möglich.In Figure 1, the control signal S2 indicates that the tensioning device 22 for controlling and / or regulating the Tension depending on the winding diameter of the Control device 28 is acted upon. About this control device 28 is also preferably the belt drive speed controllable or regulable. This belt drive speed too can in turn depend on Winding diameter can be variable. At the beginning of each Winding process can be provided, the drive speed preferably relatively quickly from zero to a predetermined one Increase value. The preferably over the pulley R5 belt drive can also be controlled in this way be that the belt drive speed during the Winding process at least temporarily with increasing winding diameter decreases. Basically, however, is also a belt drive with at least temporarily constant belt drive speed possible.

    Grundsätzlich kann der Riemenantrieb auch über eine andere Umlenkrolle als die Rolle R5, durch mehrere Rollen oder auf andere Weise erfolgen. Die Steuerung bzw. Regelung der Riemenantriebsgeschwindigkeit erfolgt jedoch auch in diesen Fällen vorzugsweise wieder über die Steuereinrichtung 28, durch die vorteilhafterweise auch das automatische Abnehmen der Wickelscheiben 32, 34, das automatische Auswerfen des Wattenwickels 12 durch Verschwenken des Schwenkhebels 26, das automatische Abführen des Wattenwickels 12 zu einer Transporteinrichtung oder dergleichen und/oder das automatische Einführen und Einspannen einer neuen Hülse H gesteuert wird. Grundsätzlich ist es auch denkbar, das Anwickeln zu automatisieren und über die Steuereinrichtung 28 zu steuern.Basically, the belt drive can also be another Deflection roller as the roller R5, through several rollers or on other way. The control of the belt drive speed however, it also takes place in these Cases preferably again via the control device 28, due to the advantageously also the automatic removal the winding discs 32, 34, the automatic ejection of the Wadding roll 12 by pivoting the pivot lever 26, the automatic removal of the wadding roll 12 to one Transport device or the like and / or the automatic Inserting and clamping a new sleeve H controlled becomes. Basically, it is also conceivable to start up to automate and via the control device 28 Taxes.
