Description

Die Erfindung betrifft eine Aufwindevorrichtung nach dem Oberbegriff des ersten unabhängigen Anspruchs sowie ein Betriebsverfahren für eine Aufwindevorrichtung.The invention relates to a winding device according to the preamble of the first independent claim and an operating method for a winding device.

Aus der schweizerischen Patentschrift 624 910 ist eine Aufwindevorrichtung dieser Gattung bekannt, bei der ein Dorn zur Aufnahme einer Hülse und somit einer Garn- oder Fadenpackung mittelbar. d.h. über eine Reibwalze oder einen Beschleunigungsring, antreibbar ist.From the Swiss patent 624 910 a winding device of this type is known in which a mandrel for receiving a sleeve and thus a yarn or thread package indirectly. i.e. via a friction roller or an acceleration ring, can be driven.

Im weiteren ist eine Aufwindvorrichtung aus der US 5605294 bekannt, in welcher die Reibwalze gegenüber den Fadenpackungen in einer kontrollierten Bewegung bewegbar ist, um beim Start der Maschine den Abstand zwischen den Packungen und der Reibwalze in einem vorgegebenen Ablauf zu erhalten. Dabei wird die Länge der Bewegung gemessen, um den genannten Abstand richtig einhalten zu können. Die Fadenpackungen sind abwechslungsweise von einem von zwei Spulendomen aufgenommen, welche an einer Drehscheibe dreh- und antreibbar gelagert sind und für den Spulenwechsel die Drehscheibe entsprechend gedreht wird. Ausserdem sind die beiden Spulendome je durch einen individuellen Motor angetrieben. Das Letztere gilt auch für die Reibwalze. Im weiteren sind Mittel vorgesehen, um den Schlupf zwischen der Reibwalze und der Oberfläche der Fadenpackungen festzustellen.Furthermore, a winding device from US Pat. No. 5,605,294 is known, in which the friction roller can be moved in a controlled movement with respect to the thread packages in order to obtain the distance between the packages and the friction roller in a predetermined sequence when the machine is started. The length of the movement is measured in order to be able to comply with the said distance correctly. The thread packages are taken alternately by one of two spool domes, which are rotatably mounted and driven on a turntable and the turntable is rotated accordingly for the bobbin change. In addition, the two coil dome are each driven by an individual motor. The latter also applies to the friction roller. In addition, means are provided to determine the slip between the friction roller and the surface of the thread packages.

Mit der steigenden Leistung von Spulmaschinen bzw. Aufwindevorrichtungen genügen reibschlüssige Kraftübertragungen zwischen verschiedenen rotierenden Elementen den Anforderungen nicht mehr.With the increasing performance of winding machines or Aufwindevorrichtungen frictional force transmission between different rotating elements no longer meet the requirements.

Es ist deshalb Aufgabe der Erfindung, eine Aufwindevorrichtung so weiterzuentwickeln, dass ein störungsfreier Betrieb und andererseits höhere Leistungen, d.h. Drehzahlen der Aufwindevorrichtungen, möglich werden.It is therefore an object of the invention to develop a winding device so that a trouble-free operation and on the other hand higher powers, i. Speeds of Aufwindevorrichtungen be possible.

Diese Aufgabe wird mit einer Aufwindevorrichtung mit den Merkmalen des ersten unabhängigen Anspruchs gelöst. Die abhängigen Ansprüche betreffen vorteilhafte Ausgestaltungen des allgemeinen Erfindungsgedankens. Die Verfahrensansprüche definieren Verfahrensschritte, mit welchen die Fadenqualität und die Ökonomie gesteigert werden.This object is achieved with a winding device having the features of the first independent claim. The dependent claims relate to advantageous embodiments of the general inventive concept. The method claims define method steps with which the thread quality and the economy are increased.

Es wird eine Aufwindevorrichtung für Endlosfäden mit einer Drehscheibe vorgeschiagen, in deren Peripherie mindestens zwei Spanndome drehbar gelagert sind, und mit einer Reibwalze, deren Welle ebenso wie eine andere Welle der Drehscheibe in einem Gestell montiert ist, und wobei die andere Welle mit einer ersten Antriebsvorrichtung und die erstere Welle mit einer zweiten Antriebsvorrichtung verbunden ist, und wobei jeder Spanndorn mit einer eigenen dritten Antriebsvorrichtung bzw. vierten Antriebsvorrichtung ausgestattet ist Mindestens eine der erwähnten Antriebsvorrichtungen besteht aus einem programmgesteuerten lnverter oder Wechselrichter und einem von ihm mit Strom versorgten Elektromotor. Die Spanndome sind mittels je eines Schwenkarms auf der Drehscheibe gelagert. Jeder Spanndorn ist durch eine Schwenkantriebsvorrichtung schwenkbar auf der Drehscheibe gelagert. Die Spanndome sind auf der Drehscheibe mittels Stellmotoren verschwenkbar. Im Bereich der Reibwalze ist mindestens eine Fadeneinzugsvorrichtung, eine Changiervorrichtung, eine Schiebeeinrichtung und/oder eine Abhebevorrichtung gelagert. Für die Reibwalze kann ein mit ihr am Umfang oder insbesondere mit ihrer Welle kuppelbarer Hilfsantrieb vorgesehen sein. Der Changiervorrichtung wird vorzugsweise eine Steuerung zugeordnet, welche ein Programmodul zur Erzeugung einer Stufenpräzisionswinklung enthält. Zur Verstellung einer Schiebeeinrichtung kann ein Doppelschusszylinder verwendet werden. Die Welle der Reibwalze und die andere Welle der Drehscheibe oder allgemein des drehbaren Trägers können ortsfest angeordnet sein.There is an endless winding device with a turntable voriagen, in the periphery of which at least two tensioning domes are rotatably mounted, and with a friction roller whose shaft is mounted as well as another shaft of the turntable in a frame, and wherein the other shaft with a first drive device and the former shaft is connected to a second drive device, and each mandrel is provided with its own third drive device. At least one of the mentioned drive devices consists of a program controlled inverter or inverter and an electric motor supplied by it. The tensioning domes are mounted on the turntable by means of one swivel arm each. Each mandrel is pivotally supported by a pivot drive device on the turntable. The tensioning domes are pivotable on the turntable by means of servomotors. In the region of the rubbing roller, at least one thread take-up device, a traversing device, a pushing device and / or a lifting device are mounted. For the friction roller can be provided with it on the periphery or in particular with its shaft coupled auxiliary drive. The traversing device is preferably associated with a controller which contains a program module for generating a step precision angle. To adjust a sliding device, a double-headed cylinder can be used. The shaft of the friction roller and the other shaft of the turntable or generally the rotatable carrier may be arranged stationary.

Einer zweiten Antriebseinrichtung der Reibwalze und einer dritten bzw. vierten Antriebseinrichtung eines Spanndorns muss eine gemeinsame Hauptsteuerung übergeordnet sein. Vorzugsweise ist damit die Lastverteilung zwischen der zweiten Antriebseinrichtung und der dritten oder vierten Antriebseinrichtung programmgemäss veränderbar. Im übrigen müssen aber die erwähnten Antriebseinrichtungen bezüglich ihrer Drehgeschwindigkeit derart gesteuert sein, dass jeweils die Umfangsgeschwindigkeiten der Reibwalze und einer Fadenpackung auf einem Spanndorn nicht wesentlich voneinander abweichen.A second drive means of the friction roller and a third or fourth drive means of a mandrel must be superordinate to a common main control. Preferably, the load distribution between the second drive device and the third or fourth drive device is thus programmably variable. Moreover, however, the mentioned drive means must be controlled with respect to their rotational speed such that in each case the peripheral speeds of the friction roller and a thread package on a mandrel do not differ substantially from each other.

Im Aufwindebereich eines Spanndorns kann eine Verwirbelungswippe mittels einer Feder und einer Luftdüse vorgesehen werden, welche Verwirbelungswippe an eine Fadenpackung andrückbar ist, wobei die Luftdüse in diesem Bereich zur Verspätung der Bildung eines Endwulstes auf der Fadenpackung dient Im Gestell der Aufwindevorrichtung wird eine Fadenpackungshebeeinrichtung vorgesehen, die den Wechsel bzw. Abtransport der Fadenpacfcungen erleichtert. Vorzugsweise wird eine Blockiervorrichtung für die Fadenpackungshebeeinrichtüng in bestimmten Betriebsphasen aktiv. An der Fadeneinzugsvorrichtung wird je nach Erfordernis eine Trennvorrichtung mit Trennlappen für Fadenenden montiert. Für die Changiervorrichtung kann ein Changierschmiersystem bereitgestellt werden. Mit dem Einschalten der Hauptsteuerung der Aufwindevorrichtung wird vorzugsweise mindestens eine dritte Antriebseinrichtung oder vierte Antriebseinrichtung des jeweils betreffenden Spanndorns eingeschaltet, so dass nach Betätigung einer Fadeneinzugsvorrichtung nach Einschalten der Maschine der Faden ohne Wartezeit auf eine Hülse eines Spanndorns angesetzt werden kann.In the winding area of a mandrel, a swirl rocker can be provided by means of a spring and an air nozzle, which swirl rocker can be pressed against a thread package, wherein the air nozzle in this area serves to delay the formation of an end bead on the thread package. In the frame of the winding device, a thread package lifting device is provided the change or removal facilitates the Fadenpacfcungen. Preferably, a blocking device for the Fadenpackungshebeeinrichtüng in certain phases of operation is active. At the thread collection device, a separator with dividing tabs for thread ends is mounted as required. For the traversing device, a traversing lubrication system can be provided. With the switching on of the main control of the winding device, preferably at least one third drive device or fourth drive device of the respectively relevant mandrel is switched on, so that after actuation of a thread retraction device after switching on the machine, the thread can be applied without waiting for a sleeve of a mandrel.

Durch die individuellen Antriebe für die Reibwalze bzw. Kontaktwalze als auch für die Spanndorne oder Spulendorne gelingt es, den Faden insbesondere während des Wechselvorgangs von einer Spule auf die jeweils nachfolgende besonders schonend zu behandeln, so dass keine Relativbewegungen zwischen dem Faden und den Oberflächen der Sputen bzw. Walzen, die in Berührung mit dem Faden stehen, in Kauf genörnmen werden müssen.The individual drives for the friction roller or contact roller as well as for the mandrels or winding mandrels, it is possible to treat the thread especially during the change process from a spool to the respective subsequent particularly gentle, so that no relative movements between the thread and the surfaces of the spurs or rolls that are in contact with the thread, must be in purchase genörnmen.

Die Antriebe einerseits für die Verschiebung der Spanndome relativ zur Drehscheibe bzw. zum Revolver und andrerseits für den Revolver erlauben es, dass der Spulenwechselvorgang unabhängig vom Anwickeln der neuen Spule bzw. umgekehrt von statten gehen kann.The drives on the one hand for the displacement of the tensioning dome relative to the turntable or to the revolver and on the other hand for the revolver allow the bobbin changing process regardless of the winding of the new coil or vice versa can go from equip.

Ein Faden 23 wird von oben in den Bereich des Gestells 14 von einer Spinnvorrichtung zugeführt, zwischen eine Schiebeeinrichtung 22 und eine Changiervorrichtung 20, an der eine Abhebevorrichtung 24 für den Faden einsetzbar ist. Der Faden 23, gestrichelt gezeichnet, wird nach dem Ablaufen von der Changiervorrichtung 20 über den unteren rechten Teil des Umfangs einer Reibwalze 2 in Richtung auf einen Spanndorn 10 mit einer Hülse 19 umgelenkt. Zu Beginn eines Aufwindeprozesses, d.h. nach dem Vorlegen eines frisch gesponnenen oder behandelten Fadens 23, tritt eine Fadeneinzugsvorrichtung 18 in Aktion, welche den Faden 23 oberhalb des Gestells 14 erfasst und über den Umfang einer Hülse 19 legt.A yarn 23 is fed from above into the region of the frame 14 by a spinning device, between a sliding device 22 and a traversing device 20, to which a lifting device 24 for the yarn can be inserted. The thread 23, shown in phantom, is deflected after the passage of the traversing device 20 over the lower right part of the circumference of a friction roller 2 in the direction of a mandrel 10 with a sleeve 19. At the beginning of a winding process, i. after presenting a freshly spun or treated thread 23, a thread retracting device 18 comes into action, which detects the thread 23 above the frame 14 and placed over the circumference of a sleeve 19.

Neben dem ersten Spanndorn 10 bei der Hülse 19 ist ein zweiter Spanndorn 8 mit einer Hülse 17 vorgesehen, und beide sind auf einer Drehscheibe 6 oder Revolver gelagert, welche bzw. welcher über eine Welle 12 mit einer ersten Antriebsvorrichtung 120 in Verbindung steht. Die Drehscheibe 6 und die erste Antriebsvorrichtung 120 sind jeweils beim Wechseln der Positionen des ersten Spanndorns 10 und des zweiten Spanndorns 8 sowie während eines teils eines Spulenaufbaus in Bewegung. Die Spanndorne 10 und 8 sind über Schwenkarme 81 bzw. 16 schwenkbar auf der Drehscheibe 6 befestigt.In addition to the first mandrel 10 in the sleeve 19, a second mandrel 8 is provided with a sleeve 17, and both are mounted on a turntable 6 or revolver, which or via a shaft 12 with a first drive device 120 is in communication. The turntable 6 and the first drive device 120 are each in motion when changing the positions of the first mandrel 10 and the second mandrel 8 and during a part of a coil assembly. The mandrels 10 and 8 are pivotally mounted via pivot arms 81 and 16 on the turntable 6.

Sobald der Faden 23 mit der Hülse 19 verbunden ist, kann der Aufsputprozess beginnen. Zum Antrieb der Reibwalze 2. auch Tachowalze genannt, dient eine Welle 4 mit einer zweiten Antriebsvorrichtung 40. Zum Antrieb des Spanndorns 8 bzw. 10 ist eine dritte Antriebseinrichtung 80 bzw. eine vierte Antriebseinrichtung 100 auf der Drehscheibe 6 befestigt. Da Schwenkarme 80 bzw. 16 verwendet werden, benötigt man zu deren Verstellung eine Schwenkantriebsvorrichtung 82 mit einem Stellmotor 83 bzw. eine zweite Schwenkantriebsvorrichtung 11 mit einem Stellmotor 13.Once the thread 23 is connected to the sleeve 19, the sputtering process can begin. To drive the friction roller 2 also called speedometer roll, a shaft 4 with a second drive device 40 is used to drive the mandrel 8 and 10, a third drive means 80 and a fourth drive means 100 is mounted on the turntable 6. Since pivot arms 80 and 16 are used, one needs to adjust them a pivot drive device 82 with a servomotor 83 and a second pivot drive device 11 with a servomotor 13th

Soweit es sich um den Antrieb rotierender Walzen wie beispielsweise des Spanndorns 8 oder der Reibwalze 2 handelt, werden bevorzugt Asynchronmotoren verwendet, welche insbesondere durch Wechsel mit verstellbarer Ausgangsfrequenz mit Strom versorgt sind. Die anderen Stellmotoren, beispielsweise die erste Antriebseinrichtung 120 zur Verdrehung der Drehscheibe 6 oder die Stellmotoren 83 bzw. 13 können als mechanische oder pneumatische oder elektromechanische Stellmotoren ausgebildet sein.As far as it is the drive of rotating rollers such as the mandrel 8 or the friction roller 2, asynchronous motors are preferably used, which supplies in particular by changing with adjustable output frequency with power are. The other servo motors, for example, the first drive means 120 for rotating the turntable 6 or the servo motors 83 and 13 may be formed as mechanical or pneumatic or electro-mechanical servo motors.

Im unteren Teil des Gestells 14 befindet sich eine Fadenpackungshebeeinrichtung 36, mit welcher fertig bewickelte und nach unten verschwenkte Fadenpackungen mit den dazugehörigen Hülsen 17 bzw. 19 aus der Wickelvorrichtung entfernt werden können.In the lower part of the frame 14 is a thread package lifting device 36, with which finished wound and downwardly pivoted thread packages can be removed with the associated sleeves 17 and 19 from the winding device.

Der Changiervorrichtung 20 kann eine Steuerung 20a zugeordnet werden, welche ein Programmodul zur Erzeugung einer Stufenpräzisionswirkung enthält. Ein Doppelschusszylinder 28 kann zur Verstellung einer Schiebeeinrichtung 22 vorgesehen werden. Einer zweiten Antriebseinrichtung 40 der Reibwalze 2 und einer dritten Antriebseinrichtung 80 des Spanndorns 8 sowie einer vierten Antriebseinrichtung 100 des Spanndorns 10 wird, wie in Figur 1 angedeutet, eine gemeinsame Hauptsteuerung 30 übergeordnet, mit welcher die Lastverteilung jeweils zwischen der zweiten Antriebseinrichtung 40 und der dritten Antriebseinrichtung 80 oder vierten Antriebseinrichtung 100 programmgemäss veränderbar ist.The traversing device 20 may be associated with a controller 20a which includes a program module for generating a step precision effect. A double-shot cylinder 28 can be provided for adjusting a sliding device 22. A second drive means 40 of the friction roller 2 and a third drive means 80 of the mandrel 8 and a fourth drive means 100 of the mandrel 10, as indicated in Figure 1, a common main control 30 superordinate, with which the load distribution respectively between the second drive means 40 and the third Drive device 80 or fourth drive device 100 can be changed according to the program.

Im Aufwindebereich eines Spanndorns 8 oder 10 ist eine schematisch dargestellte Verwirbelungswippe 32 mittels einer Feder an eine Fadenpackung auf einem Spanndorn 8 oder 10 andrückbar; weiter kann eine Luftdüse, nicht gezeichnet, in diesem Bereich zur Verspätung der Bildung des Endwulstes vorgesehen werden. Im Gestell 14 kann der Fadenpackungshebeeinrichtung 36 eine Blockiervorrichtung zugeordnet werden. Bei der Fadeneinzugsvorrichtung 18 ist schematisch eine Trennvorrichtung 38 für abstehende Fadenenden einsetzbar. Die Changiervorrichtung 20 ist vorteilhafterweise mit einem Changierschmiersystem 400 ausgerüstet.In Aufwindebereich a mandrel 8 or 10, a schematically illustrated Verwirbelungswippe 32 by means of a spring to a thread package on a mandrel 8 or 10 can be pressed; Furthermore, an air nozzle, not shown, may be provided in this area to delay the formation of the end bead. In the frame 14, the thread package lifting device 36 can be associated with a blocking device. In the thread-pulling device 18, a separating device 38 for protruding thread ends can be used schematically. The traversing device 20 is advantageously equipped with a traversing lubrication system 400.

Ein besonderes Problem stellt die Konstanthaltung oder Veränderung der Anpresskraft zwischen der Reibwalze 2 und der jeweils zugeordneten Fadenpackung dar, deren Achsabstand in Figur 2 mit D bezeichnet ist. Nach dem Weiterdrehen der Drehscheibe 6 um jeweils 180° nach Fertigstellung einer Fadenpackung wird der jeweils nachfolgende Spanndorn mit der daraufgesteckten Hülse 19 von neuem mit einem Faden 23 bzw. mehreren Fäden bewickelt. Es hat sich als vorteilhaft herausgestellt, während des Aufbaus einer neuen Fadenpackung auf einem Dorn 8 die Anpresskraft zwischen den Fadenlagen auf dem Dorn und der Reibwalze 2 oder Tachowalze zu kontrollieren. Es ist möglich, die Anpresskraft nach einem bestimmten Programm zu variieren. Dies wird dadurch erreicht, dass der Spanndorn 10 durch eine Anpresseinrichtung gegen die Reibwalze 2 gedrückt wird. Dies kann dadurch geschehen, dass ein Drehmoment im Uhrzeigersinn auf die Drehscheibe 6 ausgeübt wird, oder dass bei blockierter Drehscheibe 6 der Spanndorn 10, der in diesem Fall gegenüber der Drehscheibe 6 verschiebbar gelagert sein muss, durch eine andere Anpresseinrichtung zwischen der Drehscheibe 6 und einem Schwenkarm 16, 81 gegen die Reibwalze 2 oder Tachowalze gedrückt wird. Für die Reibwalze 2 kann ein Hilfantrieb 26 vorgesehen sein.A particular problem is the constancy or change in the contact force between the friction roller 2 and the respectively associated thread package whose center distance is denoted by D in FIG. After turning the turntable 6 by 180 ° after completion of a thread package of each subsequent mandrel with the plugged sleeve 19 is rewound with a thread 23 or more threads. It has been found to be advantageous during the construction of a new thread package on a mandrel 8 to control the contact force between the thread layers on the mandrel and the friction roller 2 or taching roller. It is possible to vary the contact pressure according to a specific program. This is achieved in that the mandrel 10 is pressed by a pressing device against the friction roller 2. This can be done by a torque is applied clockwise to the hub 6, or that with blocked turntable 6 of the mandrel 10, which must be slidably mounted in this case relative to the hub 6, by another pressing device between the hub 6 and a Swing arm 16, 81 is pressed against the friction roller 2 or speedometer roller. For the friction roller 2, an auxiliary drive 26 may be provided.
