Description
Die vorliegende Erfindung betrifft ein Verfahren zum Aufwickeln eines Fadens auf eine Spule, bei welchem der Faden von einem im wesentlichen parallel zur Spulenachse hin- und hergehend antreibbaren Fadenführer geführt und zwischen dem Fadenführer und dem Ablagepunkt auf der Spule ein freies Fadenstück, die sogenannte Schlepplänge, gebildet ist, und bei welchem die Länge des Hubs des Fadenführers und die Fadenablage beliebig variabel sind.The present invention relates to a method for winding a thread on a bobbin, in which the thread reciprocates from a substantially parallel to the bobbin axis drivable thread guide and between the thread guide and the storage point a free piece of thread, the so-called drag length, is formed on the bobbin, and with which the length of the stroke of the thread guide and the thread deposit are variable.
Bei allen heute eingesetzten Spulsystemen mit einer Einrichtung zur Fadenverlegung ist die Schlepplänge vorhanden, die je nach verwendetem Verlegesystem sehr unterschiedlich sein kann. Als Beispiele für moderne Spulsysteme seien die in der EP-A-0 453 622, EP-A-0 829 444 und EP-A-0 838 422 beschriebenen Aufwickelvorrichtungen erwähnt, wobei die ersten beiden dieser Spulsysteme nach dem eingangs genannten Verfahren arbeiten. Bei diesen Systemen ist zu beobachten, dass das auf der Spulenhüle abgelagerte Fadenpaket einen kleineren Hub hat als der Fadenführer, was selbstverständlich unerwünscht ist, weil alleine schon aus Gründen der genauen Einstellbarkeit und Reproduzierbarkeit die genannten Hübe identisch sein sollten.In all winding systems used today with a device for thread laying is the Drag lengths available, which vary greatly depending on the installation system used can. Examples of modern winding systems are those in EP-A-0 453 622, EP-A-0 829 444 and EP-A-0 838 422 mentioned, the first two of these winding systems work according to the method mentioned at the beginning. With these systems it can be observed that the thread package deposited on the bobbin tube has a smaller stroke has as the thread guide, which is of course undesirable, because just by itself Because of the exact adjustability and reproducibility the mentioned strokes are identical should be.
Untersuchungen haben gezeigt, dass die Hubverkürzung proportional zur Schlepplänge und zur Verlegegeschwindigkeit zunimmt. Die an sich naheliegenden Massnahmen zur Verringerung der Hubverkürzung, nämlich Reduktion der Schlepplänge und/oder der Verlegegeschwindigkeit können aber aus naheliegenden Gründen nicht eingesetzt werden. Denn eine Reduktion der Verlegegeschwindigkeit würde dem allgemeinen Trend der ständigen Produktivitätssteigerung widersprechen, und die Schlepplänge muss eine gewisse Mindestgrösse aufweisen, um die Gefahr von Beschädigung des Fadenführers und/oder der Spule auszuschalten.Studies have shown that the stroke shortening is proportional to the towing length and to the laying speed increases. The obvious measures for Reduction of the stroke shortening, namely reduction of the towing length and / or the Laying speeds cannot be used for obvious reasons. Because a reduction in laying speed would be the general trend of permanent Increase productivity, and the drag length must be a certain Have minimum size to avoid the risk of damage to the thread guide and / or Turn off the coil.
Durch die Erfindung sollen nun ein Verfahren und eine Vorrichtung angegeben werden, durch welche die genannte Hubverkürzung kompensiert und in geeigneter Weise ausgeregelt oder bei der Spulenherstellung bewusst eingesetzt werden kann.The invention is intended to provide a method and a device by which compensates for the shortening of the stroke and compensates for it in a suitable manner or can be used deliberately in the production of coils.
Die gestellte Aufgabe wird erfindungsgemäss dadurch gelöst, dass aus einem oder mehreren der Parameter Spulgeschwindigkeit, Fadenverlegegeschwindigkeit, Fadenführerbeschleunigung, Fadenführerverzögerung und Abstand zwischen Fadenführer und Spule die Hubverkürzung auf der Spule berechnet und für eine positionsgenaue Ablage des Fadens auf der Spule verwendet wird. The object is achieved according to the invention in that one or more the parameters winding speed, thread laying speed, thread guide acceleration, Thread guide deceleration and distance between thread guide and bobbin shorten the stroke calculated on the bobbin and for precise positioning of the thread on the bobbin is used.
Der Hauptvorteil des erfindungsgemässen Verfahrens besteht darin, dass es eine positionsgenaue Ablage des Fadens auf der Hülse ermöglicht, ohne dass die Schlepplänge oder die Fadenverlegegeschwindigkeit reduziert werden müssen. Man vermeiden dadurch die Gefahr der Beschädigung der Spule und/oder des Fadenführers und erhält einen grösseren Spielraum für die Anordnung der mechanischen Teile. Ausserdem kann auf eine Stützwalze verzichtet werden, was bekanntlich mit einer markanten Änderung der Schlepplänge über die Spulreise verbunden ist. Diese Einsparung ist deswegen möglich, weil die erfindungsemässe Methode der Berechnung der Hubverkürzung aus den genannten Parametern selbstverständlich Schwankungen der Schlepplänge mitberücksichtigt und kompensiert.The main advantage of the method according to the invention is that it is an exact position The thread can be deposited on the sleeve without the drag length or the thread laying speed need to be reduced. This avoids the risk of Damage to the bobbin and / or the thread guide and receives a greater scope for the arrangement of the mechanical parts. In addition, there is no need for a backup roller, which is known to be associated with a striking change in the tow length over the winding cycle is. This saving is possible because the method of the invention Calculation of the stroke shortening from the parameters mentioned, of course, fluctuations the drag length is taken into account and compensated.
Der Verzicht auf die Stützwalze ist besonders bei der Herstellung sogenannter Kingspools, das sind Spulen auf Hülsen mit einseitigem, komischem Flansch, sehr vorteilhaft, weil dann ein wesentlich kürzerer Fadenführer eingesetzt werden kann, was sich auf die Lebensdauer des Antriebs und auf die Verlegegeschwindigkeit positiv auswirkt. Ausserdem braucht der Abstand zwischen Hülse und Verlegeaggregat nicht an den jeweiligen Hülsendurchmesser angepasst zu werden.The omission of the backup roller is particularly important in the manufacture of so-called kingspools are spools on cores with one-sided, strange flange, very advantageous, because then an essential Shorter thread guides can be used, which affects the life of the drive and has a positive effect on the laying speed. In addition, the distance between Sleeve and laying unit are not adapted to the respective sleeve diameter become.

Mit der erfindungsgemässen Vorrichtung können ohne Stützwalzen beliebige Spulen hergestellt werden, neben den schon erwähnten Kingspools beispielsweise zylindrische, bikonische und konische Spulen, rotationssymmetrische Spulen jeglicher Form, auf Hülsen mit einseitigem Konus oder doppelseitigen Konen oder mit Absätzen, und es können die bei Stufenpräzisionswicklung auftretenden Hubänderungen bei den Geschwindigkeitssprüngen kompensiert werden. Selbstverständlich kann der Algorithmus neben der Stufenpräzisionswicklung auch bei den anderen Wickeigesetzen wie wilde Wicklung, Präzisionswicklung und Parallelwicklungen eingesetzt werden.With the device according to the invention, any coils can be produced without backup rolls are, in addition to the already mentioned Kingspools, for example cylindrical, biconical and conical coils, rotationally symmetrical coils of any shape, on sleeves with one-sided cone or double-sided cones or with shoulders, and it can be used with step precision winding occurring stroke changes in the speed jumps are compensated.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels und der Zeichnungen
näher erläutert; es zeigen:
Die in den Fig. 1 und 2 dargestellte Spulstelle besteht im wesentlichen aus einer von einem Motor
1 antreibbaren Spindel 2 zur Aufnahme und Halterung einer Spulenhülse 3, auf die eine
Spule 4, beispielsweise eine Kreuzspule, aufgewickelt wird, und aus einer Einrichtung 5 zur Verlegung
eines Fadens F, der durch ein nicht dargestelltes Lieferwerk von einer ebenfalls nicht
dargestellten Vorratsspule abgezogen und durch einen Einlauffadenführer 6 der Fadenverlegung
5 zugeführt wird. Die Spule 4 kann längs einer Mantellinie auf einer frei drehbaren Walze
(nicht dargestellt) aufliegen, die auf einem geeigneten Trägerteil der Spulmaschine montiert ist.
Wenn eine solche Walze verwendet wird, so ist es auf keinen Fall erforderlich, dass diese wie
die Stützwalze bei bekannten Spuleinrichtungen zwischen der Fadenverlegung 5 und der Spule
4 angeordnet ist. The winding unit shown in FIGS. 1 and 2 consists essentially of one from a motor
1
Die Fadenverlegung 5, die zur Herstellung der gewünschten Wicklung dient, enthält als wesentlichstes
Element einen von einem Motor 7 angetriebenen Fadenführer 8, der im wesentlichen
parallel zur Achse der Spule 4 eine hin- und hergehende Changierbewegung ausführt. Spulstellen
dieser Art sind beispielsweise in der EP-A-0 453 622, der EP-A- 0 829 444 und der EP-A-0
829 444 beschrieben, auf welche hiermit ausdrücklich Bezug genommen wird.The thread laying 5, which is used to produce the desired winding, contains the most important
Element a driven by a
Der Spindelmotor 1 und der Fadenführermotor 7 sind mit einer programmierbaren Steuerung 9
verbunden, weicher unter anderem die Drehzahlen der beiden Motoren 1 und 7 sowie Signale
eines Sensors für die Position des Fadenführers 8 zugeführt sind. Die Steuerung 9 enthält ausserdem
die Grundprogramme für die üblichen Wickelgesetze (wilde Wicklung, Präzisionswicklung,
Stufenpräzisionswicklung, konische Wicklungen mit entsprechenden Geschwindigkeitsprofilen)
und bestimmte Parameter. In der Steuerung 9 werden daraus die Wege, Geschwindigkeiten
und Beschleunigungen für den Fadenführermotor 7 und die Drehzahl für den Spulenmotor
1 aufgrund der jeweils zur Anwendung kommenden Wickelgesetze berechnet und die Motoren
1 und 7 werden entsprechend angesteuert.The spindle motor 1 and the
Die Steuerung enthält ausserdem einen Algorithmus, mit welchem aus einem oder mehreren der Parameter Spulengeschwindigkeit, Fadenverlegegeschwindigkeit, Fadenführerbeschleunigung, Fadenführerverzögerung und Abstand zwischen Fadenfüher und Spule die relativ zum Hub des Fadenführers entstehende Hubverkürzung auf der Spule berechnet und für eine positionsgenaue Ablage des Fadens F auf der Spule 4 verwendet wird. Letzteres bedeutet, dass einige der genannten Parameter, beispielsweise die Fadenverlegegeschwindigkeit und/oder die Spulengeschwindigkeit so variiert werden, dass die genannte Hubverkürzung einen bestimmten, reproduzierbaren Wert annimmt, wobei dieser Wert selbstverständlich auch gleich null sein kann.The control also contains an algorithm with which one or more the parameters bobbin speed, thread laying speed, thread guide acceleration, Thread guide delay and distance between thread guide and bobbin relative to Stroke of the thread guide resulting shortening stroke calculated on the bobbin and for a precise position Storage of the thread F on the bobbin 4 is used. The latter means that some of the parameters mentioned, for example the thread laying speed and / or the Spool speed can be varied so that the mentioned stroke shortening a certain reproducible value, which value should of course also be zero can.
Das bedeutet, dass aufgrund der genauen Kenntnis des Ablagepunkte des Fadens F auf der Spule einige der genannten Parameter so gesteuert werden können, dass die Herstellung beliebiger rotationssymmetrischer Spulen möglich ist. Solche Spulen sind beispielsweise zylindrische, bikonische oder konische Spulen, Kingspools oder Flanschspulen, und zwar jeweils ohne Stützwalze. Eine weitere Möglichkeit, welche der nachfolgend als "Schlepplängenalgorithmus" bezeichnete Algorithmus bietet, ist die freie Einstellbarkeit des Abstands zwischen Fadenführer 8 und Spule 4. Die Hubverkürzung auf der Hülse ist umso grösser, je grösser die Schlepplänge und die Verlegegeschwindigkeit sind, wobei die Schlepplänge das freie Fadenstück zwischen dem Fadenführer 8 und dem Ablagepunkt des Fadens F auf der Spule 4 bezeichnet.This means that due to the precise knowledge of the placement points of the thread F on the Coil some of the parameters mentioned can be controlled so that the production of any rotationally symmetrical coils is possible. Such coils are, for example, cylindrical, biconical or conical coils, Kingspools or flange coils, each without Backup roll. Another possibility, which of the following as "drag length algorithm" algorithm, is the free adjustability of the distance between thread guides 8 and spool 4. The shorter the stroke on the sleeve, the greater the drag length and the laying speed, the drag length being the free piece of thread between the thread guide 8 and the deposit point of the thread F on the bobbin 4.
Fig. 3 zeigt in einem Diagramm die Abhängigkeit der Hubverkürzung ΔH von der Verlegegeschwindigkeit für verschiedene Spulendurchmesser D, wobei die einseitige Hubverkürzung in Millimetern eingetragen ist. Die einzelnen Kurven + bis K6 beziehen sich von unten nach oben auf folgende Verlegegeschwindigkeiten: K1= 0.5, K2=1, K3=2, K4=3, K5=4 und K6=5m/s. Man kann der Figur entnehmen, dass die Hubverkürzung bei einem Hub des Fadenführers 8 von 200 mm bei einem kleinem Spulendurchmesser von 20mm schon bei einer mittleren Verlegegeschwindigkeit K3 von 2m/s etwa 8 mm und bei 5m/s über 18 mm beträgt.3 shows in a diagram the dependence of the stroke shortening ΔH on the laying speed for different spool diameters D, the one-sided stroke shortening in Millimeters is entered. The individual curves + to K6 relate from bottom to top to the following laying speeds: K1 = 0.5, K2 = 1, K3 = 2, K4 = 3, K5 = 4 and K6 = 5m / s. you can be seen from the figure that the stroke shortening with a stroke of the thread guide 8 of 200 mm with a small spool diameter of 20mm even with a medium laying speed K3 of 2m / s is about 8 mm and at 5m / s over 18 mm.
Der Schlepplängenaigorithmus berechnet zuerst aus den Parametern Fadenführergeschwindigkeit, Fadenführerbeschleunigung, Fadenführerverzögerung und aus der Hublänge, die prinzipiell der Länge der Spule 4 gleich sein sollte, die Bahnkurve des Fadenführers 8. Aus den Beschleunigungs- und Verzögerungszeiten werden die vom Fadenführer während der Beschleunigungs-, Verzögerungs- und Konstantfahrphase zurückgelegten Wegstrecken und aus diesen die Hubzeit und die Bahnkurve berechnet.The drag length algorithm first calculates from the parameters yarn feed speed, Thread guide acceleration, thread guide deceleration and from the stroke length, which in principle the length of the bobbin 4 should be the same, the path curve of the thread guide 8. From the acceleration and delay times are those of the thread guide during the acceleration, Deceleration and constant driving phase covered distances and from these the stroke time and the path curve are calculated.
Anschliessend wird mittels der Bahnkurve des Fadenführers, der Anfangsposition des Fadens, des Abstands zwischen Fadenführer und Spule, des Hülsendurchmessers und der Spulgeschwindigkeit der Ablagepunkt des Fadens berechnet, das ist derjenige Punkt der Packung, an dem der Faden im Zeitpunkt t abgelegt wird. Die Formel für die Berechnung des Ablagepunkts ist eine Differentialgleichung 1. Ordnung, die vorzugsweise numerisch, nämlich mit dem klassischen Runga-Kutta-Verfahren 4. Ordnung gelöst wird.Then the path of the thread guide, the starting position of the thread, the distance between the thread guide and the bobbin, the tube diameter and the winding speed the filing point of the thread is calculated, that is the point of the package which the thread is deposited at time t. The formula for calculating the drop point is a first order differential equation, which is preferably numerical, namely with the classical one Runga-Kutta procedure of the 4th order is solved.
