Abstract

PCT No. PCT/DE80/00059 Sec. 371 Date Jan. 9, 1981 Sec. 102(e) Date Jan. 9, 1981 PCT Filed May 8, 1980 PCT Pub. No. WO80/02548 PCT Pub. Date Nov. 27, 1980.During the winding of coils with a non-circular shape the wire length necessary varies periodically for a trouble-free winding per unit of time. At a high winding rotational speed and unsatisfactory side ratios relative to the coil being wound, the periodic change in the required wire length is so large that with known wire brakes there is no adequate winding quality with a concurrent protective handling of the wire. These opposite goals are reached through the invention with the aid of a controllable wire brake which essentially consists of a plurality of brake strands wound about the wire in a single layer.

Description

Die Erfindung betrifft eine Drahtbremse für eine Wickelmaschine für elektrische Spulen, bei der 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, wobei die Druckstränge an einem Ende des Druckseiles in einem in dem Schlitten oder in dem Ständer drehbar gelagerten Stellglied befestigt sind.The invention relates to a wire brake for a winding machine for electrical coils, in which the wire to be braked is wrapped in a single layer by a plurality of pressure strands of a pressure rope, which is stretched between a stand and a slide which is displaceably mounted therein by a tensioning device, the pressure strands at one end of the pressure cable are fastened in an actuator rotatably mounted in the slide or in the stand.

Grundsätzlich soll mit einer derartiggen Drahtbremse einerseits eine ausreichend große, möglichst steuerbare Bremswirkung auf den Draht bei möglichst geringer Beeinträchtigung seiner Isolation erzielt werden. Andererseits soll die Standzeit (Lebensdauer) der Druckstränge möglichst groß sein. Diese beiden Forderungen lassen sich jedoch bei einer aus der US-PS 3164335 bekannten Drahtbremse nicht gleichzeitig erfüllen : Druckstränge mit hoher Standzeit führen bei ausreichend großer Bremswirkung zu einer Beschädigung der Isolation des Drahtes. Man war daher bisher gezwungen, relativ weiches Material für die Druckstränge zu verwenden und mußte ihre kurze Standzeit in Kauf nehmen.Basically, with such a wire brake, a sufficiently large, controllable braking effect on the wire should be achieved with the least possible impairment of its insulation. On the other hand, the service life (life span) of the pressure lines should be as long as possible. However, these two requirements cannot be met at the same time in a wire brake known from US Pat. No. 3164335: pressure lines with a long service life lead to damage to the insulation of the wire with a sufficiently large braking effect. Up to now, therefore, one had to use relatively soft material for the printing strands and had to put up with their short service life.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Drahtbremse der eingangs genannten Art derart zu verbessern, daß sich eine gute Bremswirkung bei schonender Behandlung des Drahtes und hoher Standzeit erreichenläßt. Die erfindungsgemäße Lösung dieser Aufgabe ist bei einer Drahtbremse der eingangs genannten Art dadurch gekennzeichnet, daß zwischen dem zu bremsenden Draht und den Drucksträngen ein Bremsseil angeordnet ist, das ebenfalls aus mehreren, einlagig um den Draht gewickelten Bremssträngen besteht, die an einem Ende fest und am anderen Ende mittels einer Drallvorrichtung in dem Ständer eingespannt sind.The invention is therefore based on the object of improving a wire brake of the type mentioned in such a way that a good braking effect can be achieved with gentle treatment of the wire and a long service life. The inventive solution to this problem is characterized in a wire brake of the type mentioned in that a brake cable is arranged between the wire to be braked and the pressure strands, which also consists of several, single-layer wound around the wire brake strands, which are fixed at one end and other end are clamped in the stand by means of a swirl device.

Die Erfindung ermöglicht es, die Eigenschaften des Bremsseiles ausschließlich im Hinblick auf seine Bremsfunktion und eine schonende Behandlung des Drahtes hin zu optimieren, da es selbst praktisch keiner Zugspannung unterworfen ist. Man kann daher für die Bremsstränge 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 dabei gleich oder gegensinnig sein.The invention makes it possible to optimize the properties of the brake cable solely with regard to its braking function and a gentle treatment of the wire, since it itself is subject to practically no tension. One can therefore choose such a soft material for the brake lines that the surface of the wire lying within the brake cable is in contact with the brake lines at least 50%; 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 the same or opposite.

Die Funktionsteilung zwischen einem Bremsseil und einem Druckseil ermöglicht es ferner, auch für das Druckseil ein für dessen 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 the function of the pressure cable; pearl strands are just as possible here as those made of steel fibers.

Die Bremsleistung ist von der Länge des Druckseils 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 hier keine Beeinträchtigung des Drahtes oder seiner Isolation auftritt.The braking power is determined by the length of the pressure rope and the pitch of the brake strands that can be adjusted manually or by motor with the actuator, this pitch being a measure of the pressing force and the braking surface depends on the length of the brake rope. A high 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.

Die Erfindung ermöglicht auch eine einfache Konstanthaltung einer bestimmten Drahtspannung mit Hilfe eines Reglers, insbesonderes eines Dreipunktreglers. Es ist daher nicht mehr - wie beim Stand der Technik - erforderlich, die Bremsleistung auf den Maximalwert der Beschleunigung während einer Umdrehung der Wickelmaschine abzustellen ; daraus resultiert ebenfalls eine geringere Beanspruchung des Drahtes. Die für eine Regelung der Bremsleistung erforderliche schnelle Verstellung ist andererseits erst auf der Grundlage der erfindungsgemäßen Funktionsteilung zwischen Brems- und Druckseil möglich.The invention also enables a certain wire tension to be kept constant easily with the aid of a regulator, in particular a three-point regulator. It is therefore no longer necessary - as in the prior art - to switch the braking power to the maximum value of the acceleration during one revolution of the winding machine; this also results in less strain on the wire. The rapid adjustment required for regulating the braking power, on the other hand, is only possible on the basis of the division of functions according to the invention between the brake and pressure cables.

Die Erfindung wird anhand der Figuren näher erläutert ; es zeigen :

  • Figur 1 eine schematische Darstellung einer Wickeleinrichtung mit Drahtbremse,
  • Figur 2 eine Draufsicht auf eine erfindungsgemäße Drahtbremse und
  • Figur 3 eine Seitenansicht der Drahtbremse nach Fig. 2, jedoch ohne Brems- und Druckseil.
The invention is illustrated by the figures; show it :
  • FIG. 1 shows a schematic illustration of a winding device with a wire brake,
  • Figure 2 is a plan view of a wire brake according to the invention and
  • 3 shows a side view of the wire brake according to FIG. 2, but without a brake and pressure cable.

Gemäß Fig. 1 wird der Draht 8 aus einem Vorratsbehälter V über die Drahtbremse B und einen Istwertgeber 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 Sollwertgebers 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 zufriedenstellende Wicklungsqualität und die zulässige Drahtdehnung ergibt. Die hierzu erforderliche Bremsleistung wird durch den Regler auch bei Abnutzung des Bremsseiles aufrechterhalten, so daß keine überhöhten Bremswerte eingestellt werden müssen.1, the wire 8 is fed from a storage container V via the wire brake B and an actual value transmitter 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 specified by a setpoint generator. 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 quality and the permissible wire elongation result at a given winding speed. The braking power required for this is maintained by the controller even when the brake cable is worn, so that no excessive braking values have to be set.

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 über Zugstangen 43, eine Zugbrücke 42 und eine Spannstange 51 an eine pneumatisch betätigte Spannvorrichtung 5 angekuppelt.The 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 pneumatically via tie rods 43, a drawbridge 42 and a tension rod 51 actuated clamping device 5 coupled.

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 Bremsseil2 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.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 a passage 72 in the middle for the brake cable 2 and the wire 8 and receptacles 73 for the ends of the pressure strands 31, which are laid down in it. 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.

Die Stirnwand 12 weist in der Mitte einen Durchlaß 121 für den Draht8 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 1 112 einer Drallvorrichtung 111 festgelegt, die in der anderen Stirnwand 11 drehbar gelagert ist und die in der Mitte einen Durchlaß 1 111 für den Draht 8 hat, der über eine Umlenkrolle 14 zugeführt wird.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 apart on concentric circles. The other ends of the brake strands 21 are fixed in receptacles 1 112 of a swirl device 111 which is rotatably mounted in the other end wall 11 and which has a passage 1 111 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 Draht8 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 Bremsstrang 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 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 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 the 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 embodiment described.
