The disks (4) are located between a rope disk (5) driven with alternating directions, and a guide disk (3) which is stationary and located on the wire inlet side. The storage disks (4) can rotate freely in their bearings (9) and each disk features a stop (13, 14) to provide for a differential angle defining in relation to the neighbouring disk (3, 4,5).

Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen einer Kabelverseilung mit wechselnder Schlagrichtung aus Einzeldrähten, mit Scheiben mit Bohrungen zur Aufnahme der zu verseilenden Einzeldrähte, wobei sich zwischen einer mit wechselnder Drehrichtung angetriebenen Legescheibe und einer drahteinlaufseitigen, feststehenden Führungsscheibe mehrere drehbar gelagerte Speicherscheiben befinden.The invention relates to a device for producing a Cable stranding with changing direction of lay from single wires, with washers with holes to accommodate the stranded Single wires, being between one with alternating Direction of rotation driven washer and a wire inlet side, fixed guide disc several rotatably mounted Storage disks are located.

Bei bekannten Vorrichtungen werden die drehbar gelagerten Speicherscheiben z.B. über Vorgelegewellen mit unterschiedlichen Übersetzungen oder mit programmgesteuerten Einzelantrieben angetrieben. Es ist aber einerseits schwierig, solche Vorrichtungen so trägheitsarm auszuführen, daß entsprechend kurze Beschleunigungszeiten beim Drehrichtungswechsel erreicht werden, anderseits ist die Verwendung mehrerer Einzelantriebe sehr kostenaufwendig.In known devices, the rotatably mounted Storage disks e.g. over countershafts with different Translations or with program-controlled individual drives driven. But it is difficult on the one hand, such Execute devices so low inertia that accordingly short acceleration times achieved when changing direction of rotation on the other hand is the use of several individual drives very expensive.

Kurze Beschleunigungszeiten sind aber für eine gute Verseilqualität unerläßlich, damit kurze Drallwechselstellen am fertigen Seil erzielt werden. Außerdem ist die erreichbare Arbeitsgeschwindigkeit einer Verseilanlage um so größer, je kürzer die Beschleunigungszeiten (Wendezeiten) sind.Short acceleration times are, however, for good stranding quality indispensable, so that short swirl change points on the finished Rope can be achieved. In addition, the achievable working speed the shorter the shorter the stranding system are the acceleration times (turning times).

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zur Verfügung zu stellen, mit der bei möglichst geringem technischem Aufwand kurze Beschleunigungszeiten der Scheiben beim Drehrichtungswechsel erreicht werden können.The invention has for its object a generic To provide the device with which, if possible low technical effort, short acceleration times Discs can be reached when changing the direction of rotation.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Speicherscheiben in Lagern frei drehbar gelagert sind und daß jeder Speicherscheibe ein Anschlag zugeordnet ist, der mit einem der benachbarten Scheibe zugeordneten Anschlag zur Differenzwinkel-Begrenzung zusammenwirkt.According to the invention this object is achieved in that the Storage disks in bearings are freely rotatable and that each storage disk is assigned a stop, which with a stop assigned to the adjacent pane for limiting the difference angle cooperates.

Bei der Erfindung sind die Speicherscheiben in ihren Lagern ohne einen direkten oder zentralen Antrieb frei drehbar und werden im wesentlichen von den zu verseilenden Adern mitgenommen. Die Speicherscheiben haben lediglich Anschläge, die verhindern, daß gegebenenfalls die Adern zwischen zwei Speicherscheiben zu stark, nämlich z.B. mehr als um einen Differenzwinkel von etwa 180°, in die eine oder andere Richtung eingedreht werden, was den Durchlauf der Adern behindern bzw. bremsen würde. Mit dieser Anordnung wird erreicht, daß die Legescheibe ihre Drehrichtung ändern kann, ohne in ihrer Beschleunigungsphase von der Massenträgheit der Speicherscheiben behindert zu werden.In the invention, the storage disks are in their bearings freely rotatable and without a direct or central drive are essentially carried along by the wires to be stranded. The storage disks only have stops that prevent that, if necessary, the wires between two storage disks too strong, namely e.g. more than a difference angle of about 180 °, turned in one direction or the other become what hinder or slow down the passage of the veins would. With this arrangement it is achieved that the washer can change their direction of rotation without in their acceleration phase hindered by the inertia of the storage disks to become.

Vorteilhaft ist es, wenigstens einen Teil der Anschläge dämpfend oder elastisch federnd, also energiespeichernd, auszuführen. In einer Ausführungsform kann jeweils ein Anschlag an jeder Speicherscheibe als z.B. aus Federstahl bestehender Anschlagstab ausgeführt sein, der mit einem nicht federnden Anschlag an der benachbarten Speicherscheibe zusammenwirkt. In der letzten Phase vor dem Drehrichtungswechsel werden dabei die federnden Anschlagstäbe elastisch verbogen, also gespannt. Das bewirkt zunächst ein rascheres Abbremsen der Speicherscheiben bis hin zur Legescheibe, sowie des Motors, der die Legescheibe antreibt, und danach eine Beschleunigung der Legescheibe und der Speicherscheiben in die neue Drehrichtung unabhängig vom Antriebsmotor, der diese Bewegung allerdings unterstützt. Da der Antriebsmotor während des Beschleunigens aber durch die Scheiben nicht voll belastet wird, kann er sehr rasch beschleunigen, wonach die Legescheibe und der Antriebsmotor durch die Speicherscheiben über die Anschläge wieder zusätzlich belastet werden.It is advantageous to dampen at least some of the stops or elastically resilient, i.e. energy-saving. In one embodiment, one stop at a time each storage disk as e.g. made of spring steel Stop rod run with a non-resilient Stop interacts with the adjacent storage disc. In the last phase before changing the direction of rotation the resilient stop rods are elastically bent, i.e. tensioned. This initially causes the storage disks to brake more quickly to the washer and the motor that drives the Drives the washer, and then accelerates the washer and the storage disks in the new direction of rotation regardless of the drive motor, however, this movement supported. Because the drive motor during acceleration but is not fully loaded by the panes, it can do a lot accelerate quickly, after which the washer and the drive motor through the storage disks over the stops again be charged additionally.

Die Schlagrichtungswendestelle der hergestellten Verseilung wird dadurch sehr kurz. Optimal ausgelegt kann die gespeicherte Federenergie daher so groß sein, daß sie während der kurzen Beschleunigungsphase die Legescheibe zusätzlich zum Beschleunigungsmoment des Motors beschleunigt, so daß die Wendestelle am fertigen Seil besser, d.h. kürzer, ausgebildet ist. Ein weiterer Vorteil federnder Anschläge ist, daß der Legescheibenantrieb im federnden Bereich "überdrehen" darf (z.B. durch Massenträgheit bei hohen Drehzahlen), ohne Störungen oder Beschädigungen an den Anschlägen zu verursachen, wobei gleichzeitig aber verhindert wird, daß dadurch die Adern zwischen zwei Speicherscheiben um mehr als 180° eingedreht werden, was durch eine geeignete Dimensionierung der Federkennlinie der Anschläge, gegebenenfalls in Verbindung mit einem zusätzlichen fixen Anschlag, erreicht werden kann.The turn direction of the stranding produced this makes it very short. The stored can be optimally designed Spring energy should therefore be so large that it can be used during the short Acceleration phase, the washer in addition to the acceleration torque the engine accelerates so that the turning point better on the finished rope, i.e. shorter, is trained. A Another advantage of resilient stops is that the disc drive "overturn" in the springy area (e.g. by Mass inertia at high speeds), without interference or Causing damage to the stops while taking but it prevents the veins between two storage disks can be screwed in by more than 180 °, which through a suitable dimensioning of the spring characteristic of the Attacks, possibly in conjunction with an additional fixed stop, can be achieved.

In einer weiteren Ausführungsform kann vorteilhaft vorgesehen sein, daß jeder Speicherscheibe und der Legescheibe ein Vorgelegerad vorgeschaltet ist, welches mit ihrer zugehörigen Speicherscheibe gegebenenfalls über ein Getriebe verbunden ist, und daß die Anschläge an den Vorgelegerädern angeordnet sind. Die Speicherscheiben und die Legescheibe sind also in Art einer Vorgelegewelle mit Vorgelegerädern "getriebemäßig" über die Anschläge miteinander verbunden. In diesem Fall können die Speicherscheiben mit den Vorgelegerädern z.B. über Riemengetriebe, vornehmlich mit Übersetzungen ins Schnelle (d.h. das Vorgelegerad dreht langsamer als Speicherscheibe), verbunden sein.In a further embodiment, provision can advantageously be made be that each storage disc and the washer a counter gear is connected upstream, which with its associated Storage disk connected if necessary via a gear and that the stops are arranged on the counter gears are. The storage discs and the washer are in Type of countershaft with countershaft wheels "gear-like" connected to each other via the stops. In this case, you can the storage disks with the counter wheels e.g. about Belt transmission, primarily with fast translations (i.e. the counter gear rotates slower than the storage disc), be connected.

Eine Getriebeübersetzung zwischen Vorgelegerad und Speicherscheibe hat den Vorteil, daß im Zusammenwirken von Federhärte und geeigneter Wahl der Übersetzung die Federeigenschaften unter Umständen besser auf die gewünschte Auslegung entsprechend der herzustellenden Seile der Verseilmaschine abgestimmt werden können.A gear ratio between the counter gear and the storage disk has the advantage that in the interaction of spring hardness and a suitable choice of gear ratio the spring properties may be better suited to the desired design of the ropes of the stranding machine to be produced can be.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den übrigen Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispieles der Erfindung.Further features and advantages of the invention result from the remaining subclaims and the description below an embodiment of the invention.

Es zeigt:

  • Fig. 1 schematisch im Längsschnitt eine erfindungsgemäße Vorrichtung; und
  • Fig. 2 einen Schnitt durch die Vorrichtung von Fig. 1 entlang der Linie II-II.
    • It shows:
  • Figure 1 shows schematically in longitudinal section an inventive device. and
  • Fig. 2 shows a section through the device of Fig. 1 along the line II-II.

    • Eine erfindungsgemäße Vorrichtung weist an einem Maschinenrahmen 15 eine Reihe von Ständern 12, z.B. fünfzehn auf, an denen Speicherscheiben 4 und eine Legescheibe 5 in Lagern 9 frei drehbar gelagert sind. Einlaufseitig ist am ersten Ständer 12 eine feststehende Führungsscheibe 3 befestigt.A device according to the invention points to a machine frame 15 a series of stands 12, e.g. fifteen on those Storage disks 4 and a washer 5 in bearings 9 free are rotatably mounted. On the inlet side is 12 on the first stand a fixed guide plate 3 attached.

    In den Scheiben 3, 4, 5 sind eine zentrale Bohrung 11 für einen Mitteldraht 2, sowie im Radius um die Mittelbohrung 11 herum Bohrungen 10 (im vorliegenden Ausführungsbeispiel vier) vorgesehen, durch welche die zu verseilenden Einzeldrähte 1 geführt sind.In the disks 3, 4, 5 are a central bore 11 for a center wire 2, and in the radius around the center hole 11 around holes 10 (four in the present exemplary embodiment) provided by which the individual wires to be stranded 1 are led.

    Die auslaufseitig an der Vorrichtung angeordnete Legescheibe 5 wird über einen Keilriemen 7 von einem Motor 6 angetrieben, wobei der Keilriemen 7 einerseits um einen Zahnflansch 16 an der Legescheibe 5 und anderseits ein Ritzel 17 an der Antriebswelle des Motors 6 geführt ist. Der Motor 6 treibt die Legescheibe 5 mit Umdrehungen zwischen etwa 2000 und 4000 U/min an, wobei etwa zwei Drehrichtungswechsel pro Sekunde auszuführen sind. Es können dadurch etwa 10 bis 25 Schläge je Richtung am fertigen Seil erzeugt werden.The laying disc 5 arranged on the outlet side of the device is driven by a motor 6 via a V-belt 7, the V-belt 7 on the one hand around a toothed flange 16 the washer 5 and on the other hand a pinion 17 on the drive shaft of the motor 6 is guided. The motor 6 drives the Disc 5 with revolutions between about 2000 and 4000 U / min, with about two changes of direction per second are to be carried out. It can make about 10 to 25 beats each Direction on the finished rope.

    Auslaufseitig schließt an die Legescheibe 5 ein Führungsnippel 8 mit einer Bohrung an, in welcher die Einzeldrähte 1, 2 zusammengeführt werden.On the outlet side, a guide nipple connects to the washer 5 8 with a hole in which the individual wires 1, 2 are brought together will.

    Die zwischen der Einlaufscheibe 3 und der Legescheibe 5 angeordneten Speicherscheiben 4 werden im wesentlichen nur von den zu verseilenden Adern bzw. Einzeldrähten 1, 2 mitgenommen bzw. mitgedreht und verfügen somit über keinen direkten Antrieb. An den Scheiben 3, 4, 5 sind allerdings Anschläge 13 und 14 angeordnet, welche den Differenzwinkel, d.h. jenen Winkel, um den benachbarte Scheiben 3, 4, 5 gegeneinander verdreht werden können, begrenzen. Hiezu ist an den Speicherscheiben 4 auf der einen Seite ein fester Anschlag 14 angeordnet und auf der gegenüberliegenden Seite ein aus Federstahl hergestellter Anschlagstab 13, der mit dem festen Anschlag 14 der benachbarten Speicherscheibe 4 bzw. Führungsscheibe 3 zusammenwirkt und den Differenzwinkel zur benachbarten Scheibe 3, 4 auf etwas unter 180° beschränkt. Im jeweiligen konkreten Fall kann der Winkel aber auch ungleich 180° (im vorliegenden Fall vermindert um die Breite der Anschläge 13, 14), insbesondere kleiner als 180° sein.Arranged between the washer 3 and the washer 5 Storage disks 4 are essentially only from the wires or individual wires 1, 2 to be stranded or rotated and therefore have no direct drive. However, there are stops 13 on the disks 3, 4, 5 and 14 arranged which represent the difference angle, i.e. that Angle to the adjacent discs 3, 4, 5 against each other can be twisted, limit. For this is on the storage disks 4 a fixed stop 14 is arranged on one side and on the opposite side one made of spring steel manufactured stop rod 13, which with the fixed stop 14th the adjacent storage disk 4 or guide disk 3 interacts and the difference angle to the adjacent disc 3, 4 limited to a little under 180 °. In each specific In this case, the angle can also be not equal to 180 ° (in the present case Case reduced by the width of the stops 13, 14), in particular be less than 180 °.

    An der auslaufseitigen Legescheibe 5 ist nur ein federnder Anschlagstab 13 und an der einlaufseitigen Führungsscheibe 3 nur ein fester Anschlag 14 vorgesehen, die den benachbarten Speicherscheiben 4 zugewandt sind.There is only one resilient stop rod on the outlet-side washer 5 13 and on the inlet-side guide disc 3 only a fixed stop 14 is provided which adjoins the adjacent storage disks 4 are facing.

    Im Betrieb wird die Legescheibe 5 vom Motor 6 so weit verdreht, bis alle Anschlagstäbe 13 an den ihnen zugeordneten Anschlägen 14 anliegen, wobei entweder durch das Trägheitsmoment der Scheiben 4, 5 und des Motors 6 oder auch durch gezieltes längeres Antreiben des Motors 6 eine Vorspannung in den Anschlagstäben 13 erzeugt wird. Wird der Motor 6 anschließend in die Gegenrichtung beschleunigt, so wird durch die Spannung in den Anschlagstäben 13 die Legescheibe 5 ebenfalls in die Gegenrichtung beschleunigt, so daß der Antriebsmotor 6 dadurch entlastet wird und ebenfalls sehr rasch beschleunigen kann. Desweiteren ist durch eine nicht vorhandene Kopplung zwischen der Legescheibe 5 und der anschließenden Speicherscheibe 4 im Sinne der neuen Drehrichtung ein sehr schnelles Beschleunigen des Motors 6 in diese Richtung dadurch gewährleistet, daß dieser in der Beschleunigungsphase nur die Legescheibe 5 beschleunigen muß, nicht aber die anschließenden Speicherscheiben 4, so daß der Motor 5 nicht auch noch deren Trägheitsmoment überwinden muß.In operation, the laying disc 5 is rotated by the motor 6 so far until all stop rods 13 on the assigned Stops 14 abut, either by the moment of inertia the disks 4, 5 and the motor 6 or through targeted longer driving the motor 6 a bias in the stop bars 13 is generated. Then the engine 6 accelerated in the opposite direction, so the Tension in the stop bars 13, the washer 5 also accelerates in the opposite direction so that the drive motor 6 is relieved and also accelerate very quickly can. Furthermore, due to a non-existent coupling between the washer 5 and the subsequent storage disc 4 in the sense of the new direction of rotation a very fast one Accelerating the motor 6 in this direction ensures that in the acceleration phase only the washer 5 must accelerate, but not the subsequent ones Storage disks 4, so that the motor 5 not even theirs Must overcome moment of inertia.

    Dies hat zur Folge, daß durch die soeben erwähnte Entkoppelung der Legescheibe 5 und den Speicherscheiben 4 einerseits und die Federspannung der Anschlagstäbe 13 anderseits eine äußerst kurze Wendezeit der Legescheibe 5 erzielt wird, so daß die Wendestelle am fertigen Seil sehr kurz ausgebildet ist.This has the consequence that the decoupling just mentioned the washer 5 and the storage disks 4 on the one hand and the spring tension of the stop rods 13 is extremely short turning time of the washer 5 is achieved so that the Turning point on the finished rope is very short.

    Vorteilhaft bei der in den Fig. 1 und 2 dargestellten Vorrichtung ist desweiteren, daß ein Überdrehen der Legescheibe 5 und der Speicherscheiben 4 über den vorgegebenen Winkel von z.B. 180° zuverlässig verhindert wird, wobei durch die entstehende Spannung in den Anschlagstäben 13 auch der Antriebsmotor 6 sehr rasch abgebremst wird, was ebenfalls zu kurzen Wendezeiten führt. Advantageous in the device shown in FIGS. 1 and 2 is further that overturning the washer 5 and of the storage disks 4 over the predetermined angle of e.g. 180 ° is reliably prevented, the resulting Tension in the stop rods 13 also the drive motor 6 is braked very quickly, which also leads to short turning times leads.

    In diesem Zusammenhang kann auch vorgesehen sein, daß die Federkennlinie der Anschläge 13 nicht stetig, z.B. progressiv oder mit einem Knick, ausgeführt ist, so daß, nachdem die Anschläge 13 eine ausreichende Energie gespeichert haben, ein sehr rasches Abbremsen der Speicherscheiben 4 bis hin zur Legescheibe 5 und zum Antriebsmotor 6 erfolgt und somit ein Überdrehen der einzelnen Scheiben 3, 4, 5 gegeneinander über einen vorgegebenen Winkel zuverlässig verhindert wird.In this connection it can also be provided that the Spring characteristic of the stops 13 is not continuous, e.g. progressive or with a kink, so that after the Attacks 13 have stored sufficient energy very rapid braking of the storage disks 4 to Placement disc 5 and the drive motor 6 takes place and thus a Turning the individual disks 3, 4, 5 against each other a predetermined angle is reliably prevented.

    Der zulässige Federweg der Anschläge 13 ist dabei vorzugsweise so ausgelegt, daß die Summe der Federwege aller elastischen Anschläge 13 etwa jenem Drehwinkel entspricht, der für die Beschleunigung der Legescheibe beim Drehrichtungswechsel benötigt wird.The permissible spring travel of the stops 13 is preferred designed so that the sum of the spring travel of all elastic Stops 13 corresponds approximately to that angle of rotation for the Acceleration of the washer required when changing the direction of rotation becomes.

    Insgesamt wird durch die erfindungsgemäße Vorrichtung eine äußerst rasche Drehrichtungsumkehr der Legescheibe 5 erzielt, welche für eine kurze Wendestelle am fertigen Seil wesentlich ist, wobei gleichzeitig auch ein Überdrehen der einzelnen Scheiben 3, 4, 5 gegeneinander über einen vorgegebenen Winkel verhindert wird.Overall, the device according to the invention extremely rapid reversal of the direction of rotation of the disk 5 is achieved, which is essential for a short turning point on the finished rope is, at the same time overturning the individual Disks 3, 4, 5 against each other over a predetermined angle is prevented.
