Abstract

Lors du bobinage de bobines presentant une forme non circulaire, la longueur de fil necessaire par unite de temps pour obtenir un enroulement exempt de defauts varie periodiquement. Si la vitesse de rotation d'en roulement est elevee et si le rapport des dimensions de la bobine a enrouler est defavorable, la variation periodique de la longueur de fil necessaire est si grande qu'il n'est pas possible, avec les freins de fil connus, d'obtenir une qualite de bobinage suffisante si l'on veut en meme temps traiter le fil avec menagement. Ces buts opposes sont atteints par l'invention au moyen d'un frein de fil reglable qui est constitue essentiellement par plusieurs cordes de freinage (21) enroules en une seule couche autour du fil (8).When winding coils with a non-circular shape, the length of wire required per unit of time to obtain a defect-free winding varies periodically. If the rolling rotation speed is high and if the dimension ratio of the coil to be wound is unfavorable, the periodic variation of the required length of wire is so great that it is not possible, with the brakes. known thread, to obtain a sufficient quality of winding if one wants at the same time to treat the thread with care. These opposite aims are achieved by the invention by means of an adjustable wire brake which is essentially constituted by several braking cords (21) wound in a single layer around the wire (8).

Description

Drahtbremse für eine WickelmaschineWire brake for a winding machine
Beim Wickeln einer Spule ist es im Interesse eines guten Füllfaktors und eines niedrigen Drahtverbrauches erforderlich, daß der Draht an der Wickelstation immer unter einer gewissen Mindestzugspannung steht; der Draht wird deshalb vor der Wickelstation durch eine Drahtbremse geführt. Diese soll so aufgebaut sein, daß sie den Draht und insbesondere seine Isolation nicht beeinträchtigt.In the interest of a good filling factor and low wire consumption, when winding a coil it is necessary that the wire at the winding station is always under a certain minimum tensile stress; the wire is therefore passed through a wire brake in front of the winding station. This should be constructed so that it does not affect the wire and in particular its insulation.
Die Erfüllung der vorgenannten Forderungen an eine Drahtbremse bereitet erhebliche Schwierigkeiten, wenn die zur Herstellung einer Wicklung je Zeiteinheit benötigte Drahtlänge sich periodisch ändert, wie dies beim Wickeln von Spulen der Fall ist, deren Format von der Kreisform abweicht. Besonders groß sind diese Änderungen bei Spulen mit rechteckigem Format und ungünstig großem Verhältnis der Spulenlänge zur Spulenbreite, wie sie z.B. für Leuchtendrosseln benötigt werden. Besonders kritisch ist das beschriebene Problem bei sehr schnell laufenden Wickelmaschinen, da hier die erforderliche Drahtgeschwindigkeit zwischen sehr niedrigen und sehr hohen Werten schwankt. Bekannte Drahtbremsen müssen hierbei auf so hohe Bremswerte eingestellt werden, daß es häufig zu einem Drahtriß kommt.The fulfillment of the aforementioned requirements for a wire brake presents considerable difficulties if the wire length required to produce a winding per unit of time changes periodically, as is the case with the winding of coils whose format deviates from the circular shape. These changes are particularly large in the case of coils with a rectangular format and an unfavorably large ratio of the coil length to the coil width, as are required, for example, for luminaire chokes. The problem described is particularly critical in the case of very fast winding machines, since the required wire speed fluctuates between very low and very high values. Known wire brakes must be set to such high braking values that there is often a wire break.
Die Erfindung löst die angesprochenen Probleme mit einer Drahtbremse, die dadurch gekennzeichnet ist, daß der zu bremsende Draht von mehreren Drucksträngen eines Druckseiles einlagig umwickelt ist, das zwischen einem Ständer und einem in diesem verschiebbar gelagerten Schlitten durch eine Spannvorrichtung gespannt ist, und daß die Druckstränge an einem Ende des Druckseiles in einem im Schlitten oder in dem Ständer drehbar gelagerten Stellglied befestigt sind.The invention solves the problems addressed with a wire brake, which is characterized in that the wire to be braked is wrapped in a single layer by several pressure strands of a pressure rope, which is tensioned between a stand and a slide which is displaceably mounted therein, and that the pressure strands are fastened at one end of the pressure cable in an actuator rotatably mounted in the slide or in the stand.
Eine solche Drahtbremse erfordert keine zusätzlichen Umlenkrollen für den Draht, deren Masse den Draht während der Bremsphase beschleunigen würde.Such a wire brake does not require any additional deflection rollers for the wire, the mass of which would accelerate the wire during the braking phase.
Die Bremsleistung ist von der Länge des Druckseiles und der mit dem Stellglied manuell oder motorisch einstellbaren Ganghöhe der Bremsstränge bestimmt, wobei diese Ganghöhe ein Maß für die Andruckkraft ist und die Bremsfläche von der Länge des Bremsseiles abhängt. Eine große Bremsleistung läßt sich somit auf eine große Fläche des Drahtes verteilen, so daß auch hierbei keine Beeinträchtigung des Drahtes oder seiner Isolation auftritt.The braking power is determined by the length of the pressure cable and the pitch of the brake strands that can be adjusted manually or by motor with the actuator. This pitch is a measure of the pressing force and the braking surface depends on the length of the brake cable. A large braking power can thus be distributed over a large area of the wire, so that the wire or its insulation is not impaired here either.
Gemäß einer Weiterbildung der Erfindung läßt sich die Bremswirkung bei noch schonenderer Behandlung des Drahtes dadurch verbessern, daß zwischen dem zu bremsenden Draht und den Drucksträngen ein gesondertes Bremsseil angeordnet ist, das ebenfalls aus mehreren einlagig um den Draht gewickelten Bremssträngen besteht, die an ei nem Ende mittels einer Drallvorrichtung in dem Ständer eingespannt sind. Hierbei können die Eigenschaften des Bremsseiles ausschließlich auf seine Bremsfunktion hin optimiert werden, da es selbst praktisch keiner ZugSpannung unterworfen ist. Man kann daher für die Brems- stränge ein so weiches Material wählen, daß die innerhalb des Bremsseiles liegende Oberfläche des Drahtes mindestens zu 50 % in Kontakt mit den Bremssträngen steht; bei Verwendung weicher Lederstreifen läßt sich sogar eine nahezu 100 %ige Umschlingung mit einer äußerst schonenden Behandlung der Isolation verbinden. Der Wickelsinn der Stränge von Brems- und Druckseil kann gleich- oder gegensinnig sein.According to a development of the invention, the braking effect can be improved with even gentler treatment of the wire in that a separate brake cable is arranged between the wire to be braked and the pressure strands, which also consists of a plurality of brake strands wound in one layer around the wire, which on egg nem end are clamped in the stand by means of a swirl device. The properties of the brake cable can only be optimized for its braking function, since it itself is subject to practically no tension. It is therefore possible to choose such a soft material for the brake lines that the surface of the wire lying within the brake cable is at least 50% in contact with the brake lines; When using soft leather strips, an almost 100% wrap can be combined with an extremely gentle treatment of the insulation. The winding direction of the strands of brake and pressure cables can be in the same or opposite directions.
Die Funktionsteilung zwischen einem Bremsseil und einem Druckseil ermöglicht es ferner, auch, für das Druckseil ein für diese Funktion optimales Material zu verwenden; es kommen hier Perlonstränge ebenso in Betracht wie solche aus Stahlfasern.The division of functions between a brake cable and a pressure cable also makes it possible to use an optimal material for this function for the pressure cable; pearl strands are just as possible here as those made of steel fibers.
Die Erfindung ermöglicht auch eine einfache Konstanthaltung einer bestimmten Drahtspannung mit Hilfe eines Reglers, insbesondere eines Dreipunktreglers, so daß es nicht mehr nötig ist, aus Sicherheitsgründen eine überhöhte Bremsleistung einzustellen.The invention also makes it easy to maintain a certain wire voltage constant with the aid of a regulator, in particular a three-point regulator, so that it is no longer necessary to set an excessive braking power for safety reasons.

Gemäß Fig. 1 wird der Draht S aus einem Vorratsbehälter V über die Drahtbremse B und einen Istwertgeber I für die Drahtspannung der Wickelstation W eines Wickelautomaten zugeführt. Ein Regler R verändert die Bremsleistung der Drahtbremse B abhängig von der Abweichung des Istwertes von dem von einem Sollwertgeber S vorgegebenen Sollwert. Letzterer wird für eine bestimmte Wicklungsform experimentell ermittelt, indem die Bremsleistung stetig bis auf den Wert erhöht wird, bei dem sich bei einer vorgegebenen Wickeldrehzahl eine zufriedenstellendeFig. 1 is a schematic representation of a winding device with a wire brake, Fig. 2 is a plan view of a wire brake according to the invention and Fig. 3 is a side view of the wire brake according to Fig. 2, but without a brake and pressure cable. 1, the wire S is fed from a storage container V via the wire brake B and an actual value transmitter I for the wire tension to the winding station W of an automatic winding machine. A controller R changes the braking power of the wire brake B depending on the deviation of the actual value from the setpoint given by a setpoint generator S. The latter is determined experimentally for a specific type of winding by continuously increasing the braking power up to the value at which a satisfactory winding speed occurs at a given winding speed

Die Drahtbremse nach den Fig. 2 und 3 besteht aus einem Ständer 1 mit zwei Stirnwänden 11, 12 und zwischen diesen angeordneten Führungsstangen 13 für den darauf verschiebbar gelagerten Schlitten 4. Letzterer ist überThe wire brake according to FIGS. 2 and 3 consists of a stand 1 with two end walls 11, 12 and between these arranged guide rods 13 for the slide 4 slidably mounted thereon. The latter is over
Zugstangen 43, eine Zugbrücke 42 und eine Spannstange 51 an eine pneumatisch betätigte Spannvorrichtung 5 angekuppelt.Drawbars 43, a drawbridge 42 and a tie rod 51 coupled to a pneumatically operated tensioning device 5.
Der Schlitten 4 weist eine Traverse 41 auf, die in ihrer Mitte mit einer Bohrung 411 versehen ist, in der das Stellglied 7 für das Bremsseil 3 drehbar gelagert ist; es hat in der Mitte einen Durchlaß 72 für das Bremsseil 2 und den Draht 8 und Aufnahmen 73 für die Enden der Druckstränge 31, die darin festgelegt sind. Vorzugsweise sind vier solche Aufnahmen 73 im Abstand von 90° für vier Druckstränge 31 vorgesehen. Das Stellglied 7 ist ferner mit einem Kettenrad 71 ausgerüstet, das über eine Kette 9 mit dem Kettenrad 61 eines auf dem Schlitten 4 angeordneten Stellmotors 6 gekuppelt ist. Die Stirnwand 12 weist in der Mitte einen Durchlaß 121 für den Draht 8 und um diesen herum Aufnahmen 122 und 123 für die anderen Enden der Bremsstränge 21 bzw. der Druckstränge 31 auf, die auf konzentrischen Kreisen jeweils im gleichen Abstand voneinander liegen. Die anderen Enden der Bremsstränge 21 sind in Aufnahmen 1112 einer Drallvorrichtung 111 festgelegt, die in der anderen Stirnwand 11 drehbar gelagert ist und die in der Mitte einen Durchlaß 1111 für den Draht 8 hat, der über eine Umlenkrolle 14 zugeführt wird.The carriage 4 has a crossbar 41, which is provided in its center with a bore 411 in which the actuator 7 for the brake cable 3 is rotatably mounted; it has in the middle a passage 72 for the brake cable 2 and the wire 8 and receptacles 73 for the ends of the pressure strands 31 which are defined therein. Four such receptacles 73 are preferably provided at a distance of 90 ° for four printing strands 31. The actuator 7 is also equipped with a sprocket 71 which is coupled via a chain 9 to the sprocket 61 of an actuator 6 arranged on the carriage 4. The end wall 12 has in the middle a passage 121 for the wire 8 and around this receptacles 122 and 123 for the other ends of the brake strands 21 and the pressure strands 31, respectively, which are equally spaced from one another on concentric circles. The other ends of the brake strands 21 are fixed in receptacles 1112 of a swirl device 111 which is rotatably mounted in the other end wall 11 and which has a passage 1111 in the middle for the wire 8, which is fed via a deflection roller 14.
Mit Hilfe der Drallvorrichtung werden die vier Stränge 21 des Bremsseiles 2 einlagig ohne wesentliche Spannung um den Draht 8 herumgewickelt; die dazu erforderliche Position der Drallvorrichtung 111 wird durch geeignete Arretiermittel festgestellt.With the help of the twist device, the four strands 21 of the brake cable 2 are wound around the wire 8 in one layer without substantial tension; the required position of the swirl device 111 is determined by suitable locking means.
Die vier Stränge 31 des Druckseiles 3 sind einlagig um das Bremsseil herum gewickelt, wobei die Bremskraft mit abnehmender Ganghöhe der einzelnen Bremsstränge (zunehmender Winkel zwischen Bremssträng und Draht) und mit steigender Zugkraft der Spannvorrichtung 5 steigt. Letztere wird vorzugsweise auf einem Wert konstant gehalten, der unter Berücksichtigung von Material und Länge des Bremsseiles 2 sowie der Form der Wicklung und der Wickeldrehzahl experimentell ermittelt wird. Zur Veränderung der Bremsleistung wird das Stellglied 7 durch den Stellmotor 6 verdreht, wodurch der Andruck des Bremsseiles 2 an den Draht 8 erhöht oder erniedrigt wird.The four strands 31 of the pressure rope 3 are wound in one layer around the brake rope, the braking force increasing with decreasing pitch of the individual brake strands (increasing angle between the brake strand and wire) and with increasing tensile force of the tensioning device 5. The latter is preferably kept constant at a value which is determined experimentally taking into account the material and length of the brake cable 2 as well as the shape of the winding and the winding speed. To change the braking power, the actuator 7 is rotated by the servomotor 6, whereby the pressure of the brake cable 2 on the wire 8 is increased or decreased.
Abweichend von dem beschriebenen Ausführungsbeispiel kann das Stellglied 7 auch in der Stirnwand 12 angeordnet werden; der Stellmotor 6 ist dann auf dem Ständer 1 zu befestigen. Diese Lösung hat nicht nur mechanische Vorteile sondern ist auch regelungstechnisch günstig , da die durch den Stellmotor erzeugte Änderung der Bremskraft in der Nähe des Stellgliedes am stärksten ist, das dann der Wickelstation näher liegt als bei der beschriebenen Ausführungsform. In a departure from the exemplary embodiment described, the actuator 7 can also be arranged in the end wall 12; the servomotor 6 is then to be attached to the stand 1. This solution not only has mechanical advantages but is also favorable in terms of control technology, since the change in braking force generated by the servomotor is strongest in the vicinity of the actuator, which is then closer to the winding station than in the described embodiment.
