des länglichen Gegenstandes 11 auf den bzw. vom Spulenkörper
15 ist eine programmgesteuerte Einstellung des Drehzahlverlaufs sowie
des Drehmomentes des Antriebsorganes in Abhängigkeit des messbaren
Wickeldurchmessers für einen Aufwickelvorgang des Spulenkörpers vorgesehen.
Mittels eines Reglers wird der Istwert der Zugkraft via das gemessene
Drehmoment am Antriebsorgan mit einem einstellbaren Sollwert
verglichen und bei Abweichung wird dieser Istwert wieder an den Sollwert
herangeführt.In the method according to the invention for controlled winding or unwinding

Drehmomentes des Antriebsorganes wird insbesondere eine Anpassung an
das während eines Auf- oder Abwickelvorganges sich ändernde Widerstandsmoment
am Spulenkörper 15 bzw. an den sich vergrössernden Wikkeldurchmesser
erreicht. Mit grösser werdendem Wickeldurchmesser ist
vom Antrieb 20 her eine grössere Kraftübertragung erforderlich. Demgegenüber
wird die Drehzahl am Antrieb bei grösser werdendem Wickeldurchmesser
verkleinert, um eine annähernd konstant bleibende Zuführgeschwindigkeit
des länglichen Gegenstandes herbeizuführen.Through the program-controlled setting of the speed curve and the
Torque of the drive member is in particular an adjustment

Gemäss Fig.2 wird der Sollwert 54 für die Zugkraft am länglichen Gegenstand
11 via ein Potentiometer 54' oder dergleichen eingestellt und an den
Regler 50 geleitet. Parallel dazu wird der aktuelle Wickeldurchmesser 15'
von einem Sensor 52 gemessen und von einem Computer 56 oder dergleichen
für die Bestimmung der programmgesteuerten Einstellung des
Drehmomentes aufgenommen. Dieses vom Computer 56 definierte
Drehmoment dient dann zusammen mit dem Sollwert 54 als eigentliche
Sollgrösse, mittels derer der Regler 50 das Antriebsorgan 20 ansteuert.
Eine Rückmeldung des gemessenen Drehmomentes als Istwert 57 gelangt
zum Regler zurück, welcher in der Folge bei Abweichung zum Sollwert
eine Angleichung des Istwertes vornimmt. Mit der vom Computer 56 bestimmten
Einstellung des Drehmomentes wird das mit grösser werdendem
Wickeldurchmesser ändernde Widerstandsmoment ausgeglichen. Mittels
der Sollwerteingabe 54 wird die sich ändernde programmgesteuerte Einstellung
vom Computer 56 her mit einem entsprechenden Faktor für die
effektive Sollgrösse geändert.According to Figure 2, the
Gleichzeitig zur Regelung des Drehmomentes erfolgt eine Drehzahlregelung
des Antriebsorganes 20 und damit des Spulenkörpers 15. Diese Drehzahl
hängt dabei von der gewünschten Wickelgeschwindigkeit ab, welche
von den anlagenspezifischen Kenndaten, wie der Drahtbeschaffenheit, des
Drahtdurchmessers und/oder von anderen Faktoren ermittelt wird, wie
bspw. von der möglichen Zuführgeschwindigkeit, die von einer den Draht
oder ähnlichem liefernden Produktionsmaschine abhängt. Die Bestimmung
der Drehzahl erfolgt ausserdem in Abhängigkeit des Wickeldurchmessers
15', welcher vom Sensor 52 gemessen wird. Dieses an den Computer 56
gelieferte Messignal wird folglich für die programmgesteuerte Einstellung
der Drehzahl herangezogen. Diese vom Computer 56 softwaremässig definierte
Drehzahl wird als Signalgrösse an einen Regler 61 geleitet, der das
Antriebsorgan 20 mit einem Drehzahl-Sollwert ansteuert. Die definierte
Drehzahl ist dabei derart ausgelegt, dass sie zur Erzielung einer annähernd
gleich bleibenden Wickelgeschwindigkeit mit grösser werdendem Wickeldurchmesser
abnimmt. Ein Tachogenerator 62 meldet dann den Istwert der
Drehzahl am Elektromotor an den Regler 61 zurück, welcher auf an sich
herkömmliche Weise den Ist- mit dem Sollwert vergleicht und allenfalls
eine Korrektur des Sollwertes vornimmt. Die Wickelgeschwindigkeit beträgt
vorteilhaft zwischen 0 und 15 m/min, derweil das Drehmoment für
die Zugkraft in der Regel zwischen 30 und 150 Nm einstellbar ist.At the same time as controlling the torque, the speed is regulated
of the
Beim Abwickeln besteht im Zusammenhang mit der Regelung des
Drehmomentes gegenüber dem Aufwickeln insofern ein Unterschied, als
das als Elektromotor ausgebildete Antriebsorgan 20 als Bremse wirkt.
Hierdurch wird wiederum ein definiertes Drehmoment und damit eine gewünschte
Zugkraft am abwickelnden länglichen Gegenstand 11 erzeugt.
Ansonsten kann das Verfahren analog wie beim Aufwickeln benutzt werden.When unwinding exists in connection with the regulation of the
Torque compared to the winding in that a difference

Im weiteren erfolgt im Rahmen des erfindungsgemässen Verfahrens eine
exakte Verstellung des den länglichen Gegenstand 11 leitenden Führungskopfes
35. Um eine ohne Abstand erfolgende Aneinanderreihung des beispielsweise
als Draht verwendeten Gegenstandes 11 auf den Spulenkörper
15 zu ermöglichen, wird der Führungskopf 35 zu diesem Zwecke von einer
von einem Verlegermotor 36 angetriebenen Spindelwelle 38 parallel zur
Drehachse des Spulenkörpers 15 hin- und herbewegt. Die Steigung pro
Umdrehung entspricht daher annähernd dem Aussendurchmesser des aufzumickelnden
Gegenstandes. Der Sollwert der Steigung pro Umdrehung
kann mittels eines Potentiometers 64' oder dergleichen festgelegt werden.
Ein Steuerelement 64 empfängt ein Signal vom Tachogenerator 62 und
steuert mit einer proportionalen Grösse den Verlegemotor 36. so dass dieser
eine Drehzahl der Spindelwelle 38 und damit eine vorgegebene Steigung
des Führungskopfes 35 bewirkt, die pro Umdrehung der Spule 15
annähernd dem Durchmesser des aufzuwickelnden Gegenstandes 11 entspricht.Furthermore, one takes place within the scope of the method according to the invention
