Description
Die Erfindung betrifft ein Verfahren zur Ermittlung eines auf die Wickeldichte bezogenen Wickelparameters eines Bandwickelvorganges, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for determining a the winding density-related winding parameters of a tape winding process, and an apparatus for performing the method.
Bandmaterial aus Metallfolie oder aus Kunststoffolie wird zu großen Coils aufgewickelt, um an Verarbeitungsbetriebe versandt zu werden. Das Aufwickeln auf einen Wickelkern erfolgt mit hoher Geschwindigkeit, wobei Luft in den Wickel hinein gerissen wird. Ein gewisser Lufteinschluß zwischen den Windungen des Wickels ist erwünscht, weil der Wickel dadurch eine gewisse Weichheit und Elastizität erhält. Wird die eingeschlossene Luftmenge zu groß, entstehen allerdings Unrundheiten und eine nicht zu akzeptierende Weichheit des Wickels. Ein homogener und mit dem gewünschten Lufteinschluß hergestellter Wickel kann in dem Verarbeitungsbetrieb mit hoher Geschwindigkeit abgewickelt werden. Bei Wickeln von schlechterer Qualität muß dagegen die Abwickelgeschwindigkeit reduziert werden. Es besteht daher ein Bedürfnis, Bandwickelvorgänge mit definierter Wickeldichte durchführen zu können.Tape material made of metal foil or plastic foil becomes too large coils wound up to be shipped to processing plants to become. The winding on a winding core takes place with high speed, tearing air into the wrap becomes. A certain amount of air between the windings of the Wrapping is desirable because it makes the wrap a certain amount Maintains softness and elasticity. Will the included Air volume too large, but non-roundness and one arise unacceptable softness of the wrap. A homogeneous and with the desired air inclusion winding can in processed at high speed become. With winding of poor quality, however, the Unwinding speed can be reduced. There is therefore a Need for tape winding processes with a defined winding density to be able to perform.
Ein Verfahren zur Bestimmung der Wickeldichte ist beschrieben in DE 41 16 081 A1. Hierbei werden die Materialstärke, die Wickellänge und der Außendurchmesser des Wickelballens gemessen. Aus der Folienstärke, der Wickellänge und der Größe der stirnseitigen Ringfläche des Wickelballens wird die Wickeldichte ermittelt. Die Wickeldichte ist das Verhältnis des tatsächlichen Gewichtes der aufgewickelten Materialbahn im Verhältnis zu dem rein theoretisch möglichen Voll-Gewicht des Wickels ohne Lufteinschlüsse.A method for determining the winding density is described in DE 41 16 081 A1. Here, the material thickness, the Wrapping length and the outside diameter of the wrapping bale measured. From the film thickness, the wrap length and the size of the the end face of the wrapping bale becomes the wrapping density determined. The winding density is the ratio of the actual Weight of the wound material web in the ratio to the theoretically possible full weight of the Wrap without air pockets.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Ermittlung eines auf die Wickeldichte bezogenen Wickelparameters anzugeben, um mit einfachen Mitteln eine hochgenaue Bestimmung des Wickelparameters zu ermöglichen.The invention has for its object a method and a device for determining a related to the winding density Specify winding parameters to order with simple means to enable a highly accurate determination of the winding parameter.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit dem Verfahren des Patentanspruchs 1 und der Vorrichtung des Patentanspruchs 5.This object is achieved according to the invention with the method of claim 1 and the device of claim 5.
Nach der Erfindung wird der auf die Wickeldichte bezogene Wickelparameter dadurch ermittelt, daß in zwei nacheinander aufgetretenden Meßzyklen, die einer ausgewählten Anzahl von Umdrehungen des Wickelkerns entsprechen, jeweils die aufgespulte Wickellänge bestimmt wird. Die beiden Meßwerte der Wickellängen werden dann in Beziehung zueinander gesetzt, wobei unter Berücksichtigung der Materialstärke der Wickelparameter berechnet wird. Bei dem zu berechnenden Wickelparameter handelt es sich um die Wickeldichte oder um die Stärke der zwischen zwei Wickellagen eingeschlossenen Luftschicht. Das Verfahren kann mit lediglich zwei Meßeinrichtungen durchgeführt werden, von denen die eine Meßeinrichtung die Wickellänge erfaßt, während die andere die Umdrehungen des Wickelkernes umfaßt. Aus den während aufeinanderfolgender Meßzyklen gewonnenen Werten der Wickellänge können die gewünschten Wickelparameter berechnet werden, unter der Voraussetzung, daß die Materialstärke bekannt ist und konstant bleibt, oder mit einer Dickenmeßeinrichtung kontinuierlich erfaßt wird.According to the invention is related to the winding density Winding parameters determined in that one after the other occurring measuring cycles that a selected number of revolutions of the winding core correspond to that wound up Winding length is determined. The two measured values of the winding lengths are then related to each other, taking into account the material thickness of the winding parameters becomes. The winding parameter to be calculated is the winding density or the strength of the between two Wrapped layers of air. The procedure can be carried out with only two measuring devices, from which the one measuring device detects the winding length, while the other comprises the revolutions of the winding core. From the values of the values obtained during successive measuring cycles The desired winding parameters can be calculated from the winding length on condition that the material thickness is known is and remains constant, or with a thickness measuring device is continuously recorded.
Die Erfindung ermöglicht es, einen auf die Wickeldichte bezogenen Parameter nicht erst am Ende eines Wickelvorgangs zu ermitteln, sondern schon während des Wickelns zu kennen. Dies ermöglicht es, sofort Einfluß zu nehmen und eine Regelung des Parameters vorzunehmen.The invention makes it possible to refer to the winding density Not to determine parameters only at the end of a winding process, but to know already during the winding. this makes possible it to take immediate influence and regulate the parameter to make.
Generell kann von dem Umfang einer aufgewickelten Windung der Umfang der vorhergehenden Windung subtrahiert werden. Die so ermittelte Längendifferenz ist ein direktes Maß für die Durchmesserzunahme des Wickels. Die Durchmesserzunahme ist die Summe von Materialstärke plus Lufteinfluß.In general, the extent of a wound turn of the The extent of the previous turn can be subtracted. The so determined difference in length is a direct measure of the Diameter increase of the winding. The diameter increase is that Sum of material thickness plus air influence.
Die Wickeldichte WD kann nach folgender Formel berechnet
werden:
Startdurchmesser und Enddurchmesser beziehen sich auf Start und
Ende desselben Wickelzyklus. Die Stärke DL der Luftschicht kann
nach folgenden Gleichungen bestimmt werden:
Die Anzahl der Umdrehungen des Wickelkerns, die einen Meßzyklus ergeben, ist vorzugsweise ganzzahlig. In diesem Fall braucht lediglich jeweils der Nulldurchgang bei jeder Umdrehung detektiert zu werden. Die Umdrehungszahl kann durch Zählen der Nulldurchgangsimpulse bestimmt werden. So kann ein Meßzyklus beispielsweise aus exakt 10 Umdrehungen bestehen. Es ist aber auch möglich, als Meßzyklus jede andere Drehwinkelgröße zu wählen, beispielsweise 270° oder 500°. Wichtig ist, daß der Meßzyklus anhand eines definierten Drehwinkels des Wickelkernes bestimmt wird.The number of revolutions of the winding core that a measuring cycle result is preferably an integer. In this case needs only the zero crossing is detected with each revolution to become. The number of revolutions can be counted by the zero crossing pulses be determined. For example, a measuring cycle consist of exactly 10 revolutions. It is also possible to choose any other angle of rotation size as measuring cycle, for example 270 ° or 500 °. It is important that the measuring cycle determined based on a defined angle of rotation of the winding core becomes.
Das erfindungsgemäße Verfahren ist im einfachsten Fall ein reines Meßverfahrens, bei dem der Wickelparameter bestimmt wird. Der Bandwickel wird dann mit einer Information über den gemessenen Wickelparameter versehen an den Empfänger geschickt. Der Empfänger weis aufgrund des Parameters, mit welcher maximalen Abwickelgeschwindigkeit der Bandwickel abgewickelt werden darf.In the simplest case, the method according to the invention is a pure measuring method in which the winding parameter is determined becomes. The tape wrap is then provided with information about the measured winding parameters sent to the recipient. Based on the parameter, the receiver knows which maximum Unwinding speed of the tape reel to be unwound may.
Die Erfindung ermöglicht auch eine Regelung des Parameters im Sinne einer Konstanthaltung während des Wickelvorganges. Hierzu wird eine Regelung durchgeführt, wobei als Stellgröße zum Konstanthalten des Wickelparameters die Anpreßkraft einer Andrückwalze oder die Zugkraft des Antriebs des Wickelkernes verändert wird.The invention also enables regulation of the parameter in the Meaning of keeping constant during the winding process. For this a regulation is carried out, whereby as a manipulated variable for keeping constant of the winding parameter the contact pressure of a pressure roller or changed the tensile force of the drive of the winding core becomes.
Bei einer Vorrichtung, bei der die Recheneinrichtung eine Tabelle enthält, in die für jedes Intervall der errechnete Durchmesser des Winkels und der Absolutwert der Wickellänge eingeschrieben werden, besteht die Möglichkeit der Benutzung der anfallenden Daten für andere Anwendungen. Tritt beispielsweise beim Wickeln ein Bandabriß oder eine Flickstelle auf, dann ist es üblich, die betreffenden Stellen herauszuschneiden und die Bandenden auf dem Wickler mit Ultraschall zusammenzuschweißen. Vor dem Schweißen werden die letzten Lagen von dem Wickel abgewickelt. Durch dieses Abwickeln geht die aktuelle Materiallauflänge des Wickels verloren. Erfindungsgemäß kann nach einer Schweißung anhand der nächsten Meßzyklen der aktuelle Durchmesser des Wickels berechnet werden. Dieser Durchmesser wird mit den in der Tabelle abgelegten Durchmessern verglichen. Die Lauflänge des Durchmessers, der mit dem aktuellen Durchmesser korrespondiert, wird als neuer Setzwert in den Meterzähler des Wicklers geschrieben. Hierbei kann, wenn der aktuelle Durchmesser mit einem abgelegten Durchmesser nicht exakt übereinstimmt, eine Interpolation erfolgen.In a device in which the computing device has a table contains the calculated diameter for each interval of the angle and the absolute value of the winding length there is the possibility of using the accruing Data for other applications. For example, kick when winding a tape tear or a patch, then is it is customary to cut out the relevant areas and the Ultrasonically weld the ends of the strips together on the winder. The last layers are unwound from the winding before welding. The current material run length goes through this unwinding of the wrap lost. According to the invention Welding based on the next measuring cycles the current diameter of the winding can be calculated. This diameter comes with compared to the diameters stored in the table. The Barrel length of the diameter with the current diameter corresponds as a new setting value in the meter counter of the Wicklers written. Here, if the current diameter does not exactly match a stored diameter, an interpolation is done.

dargestellten) Motor angetrieben wird. Eine Materialbahn 11
wird auf dem Wickelkern 10 zu einem Spulenwickel 12 aufgewickelt.
Das Bandmaterial 11 ist eine dünne Folie aus Aluminium,
wie sie als dampfdichte Schicht Getränketüten u.dgl. benutzt
wird. Die Materialstärke beträgt 6 bis 10 µm.
Das Bandmaterial 11 kommt von einer Herstellungsstraße mit konstanter
Geschwindigkeit. Sie läuft zwischen zwei Walzen 13,14
hindurch, die schlupffrei an entgegengesetzten Seiten des Bandmaterials
angreifen und nicht angetrieben sind. Die Welle der
Walze 13 ist mit einem Impulsgeber 15 versehen, der eine hohe
Winkelauflösung hat und pro Umdrehung der Welle zahlreiche Impulse
liefert. Der Impulsgeber 15 bildet eine Meßeinrichtung 16
zur Bestimmung der zulaufenden Wickellänge.The drawing shows a winding
Mit der Welle des Wickelkernes 10 ist ein Impulsgeber 17 gekoppelt.
Dieser liefert bei jeder Umdrehung des Wickelkernes 10
einen Impuls, und zwar einen sehr kurzen Impuls bei dem Nulldurchgang.
Der Impulsgeber 17 bildet eine Meßeinrichtung 18 zur
Ermittlung der Umdrehungen des Wickelkerns 10.A
Die Meßeinrichtungen 16 und 18 sind mit einer Auswerteschaltung
19 verbunden. Diese enthält einen Zähler 20, der bis zehn zählt
und jeweils nach zehn Eingangsimpulsen einen Ausgangsimpuls erzeugt.
Die Ausgangsimpulse des Zählers 20 begrenzen jeweils
einen Meßzyklus, der hier zehn Umdrehungen des Wickelkernes
ausmacht.The
Die Impulse der Meßeinrichtung 16 werden einem Zähler 21 zugeführt,
dessen Rücksetzeingang R mit einem ODER-Tor 22 verbunden
ist. Der Zähler 21 ist mit einer Halteschaltung 23 versehen.
Diese übernimmt den Zählerstand des Zählers 21, wenn an ihrem
Latcheingang L ein Steuerimpuls auftritt. Der Latcheingang L
ist an den Ausgang des Zählers 20 angeschlossen. Wenn der Zähler
20 am Ende eines Meßzyklus einen Ausgangsimpuls erzeugt,
übernimmt die Halteschaltung 23 den Zählerstand des Zählers 21.
Dieser wird gleichzeitig über das Signal an seinem Rücksetzeingang
R auf Null zurückgesetzt. Der Rücksetzeingang R empfängt
über das ODER-Tor 22 das Ausgangssignal des Zählers 20 oder ein
Steuersignal, das von dem die Wickelanlage steuernden Schaltschrank
24 kommt.The pulses from the
Der Ausgang der Halteschaltung 23 ist über eine Leitung 25 mit

Ein Meßzyklus besteht bei dem vorliegenden Ausführungsbeispiel
aus zehn Umdrehungen des Wickelkerns 12. Während des Meßzyklus
werden die von dem Impulsgeber 15 erzeugten Impulse im Zähler
21 gezählt. Am Ende des Meßzyklus wird der Zählerstand des Zählers
21 in die Halteschaltung 23 übergeben und von dieser über
Leitung 25 an die Recheneinrichtung 26 geliefert. Gleichzeitig

from ten revolutions of the winding
Die Wickeldichte wird ermittelt nach der Formel
Beide Parameter, Wickeldichte und Stärke der eingeschlossenen Luftschicht können auf dem Bildschirm der Recheneinrichtung 26 angezeigt werden. Diese Parameter können bei der nachfolgenden Verarbeitung des Bandwickels verwertet werden. Beispielsweise wird jeder Bandwickel nach dem Wickelprozeß in einem Glühofen geglüht. Die Dauer des Glühprozesses wird wesentlich von der Menge der eingeschlossenen Luft bestimmt. In Abhängigkeit von der Stärke der eingeschlossenen Luftschicht kann die Dauer des Glühprozesses variiert werden.Both parameters, winding density and strength of the included Air layer can on the screen of the computing device 26th are displayed. These parameters can be used in the following Processing of the tape reel can be recycled. For example After the winding process, each ribbon roll is placed in an annealing furnace annealed. The duration of the annealing process depends essentially on the Determines the amount of trapped air. In dependence of the thickness of the enclosed air layer can affect the duration of the Annealing process can be varied.
Es ist auch möglich, während des Wickelprozesses eine Regelung
durchzuführen. So kann beispielsweise die Zugkraft, mit der der
Wickelkern 10 angetrieben ist, in Abhängigkeit von dem gemessenen
Parameter variiert werden. Während die Bandgeschwindigkeit
konstant ist, kann die Zugkraft des Motors verändert werden.
Eine Erhöhung der Zugkraft bedeutet eine Verringerung der
Lufteinschlüsse.It is also possible to regulate during the winding process
perform. For example, the traction with which the
Eine weitere Möglichkeit der Beeinflussung des eingeschlossenen
Luftvolumens besteht darin, den Druck einer Anpreßrolle 28 zu
verändern, die von einem Andrückorgan 27, hier einem Zylinder,
an der Auflaufstelle des Bandes 11 gegen den Wickel 12 gedrückt
wird. Eine Erhöhung der Anpreßkraft bedeutet eine Verringerung
des im Wickel einzuschließenden Luftvolumens.Another way of influencing the trapped
Air volume is the pressure of a
