- Short acceleration times are, however, for good stranding quality indispensable, so that short swirl change points on the finished Rope can be achieved.
- the achievable working speed the shorter the shorter the stranding system are the acceleration times (turning times).
- WO 94/20969 A1 describes a generic device for Establish a cable stranding known in the in the storage section
- Storage disks in tubular torsion chain links are stored. Are on these torsion chain links rigid stops are provided, via which the tubular Torsion chain links and subsequently also the storage disks have a differential angle limitation to each other.
- 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.
- this object is achieved in that the Storage disks can be rotated freely in fixed bearings are that a stop is assigned to each storage disk, the stop associated with each adjacent disc interacts to limit the difference angle, and that at least part of the stops is elastic.
- 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.
- At least some of the stops are resilient, so energy-saving, executed. Also a damping version is possible.
- one stop can be used on each storage disc as e.g. made of spring steel Stop rod run with a non-resilient Stop interacts with the adjacent storage disc.
- the resilient stop rods are elastically bent, that is curious; excited. Initially, this causes the Storage discs up to the washer, as well as the motor, which drives the washer, and then an acceleration the washer and the storage disks in the new direction of rotation regardless of the drive motor that this movement however supported. Because the drive motor during acceleration but is not fully loaded by the panes, it can accelerate very quickly, after which the disc and the drive motor through the storage disks over the stops again be burdened additionally.
- 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.
- resilient stops On 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.

- 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.
- 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.

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 und wobei jeder Speicherscheibe ein Anschlag zugeordnet ist, der mit einem einer benachbarten Scheibe zugeordneten Anschlag zur Differenzwinkel-Begrenzung zusammenwirkt.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 and being each storage disk a stop is associated with an adjacent one Disc-assigned stop for limiting the differential angle cooperates.
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).
Aus der WO 94/20969 A1 ist eine gattungsgemäße Vorrichtung zum Herstellen einer Kabelverseilung bekannt, bei der in der Speicherstrecke Speicherscheiben in rohrförmigen Torsionskettengliedern gelagert sind. An diesen Torsionskettengliedern sind starre Anschläge vorgesehen, über welche die rohrförmigen Torsionskettenglieder und in weiterer Folge auch die Speicherscheiben zueinander eine Differenzwinkelbegrenzung aufweisen. WO 94/20969 A1 describes a generic device for Establish a cable stranding known in the in the storage section Storage disks in tubular torsion chain links are stored. Are on these torsion chain links rigid stops are provided, via which the tubular Torsion chain links and subsequently also the storage disks have a differential angle limitation to each other.
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 ortsfesten Lagern frei drehbar gelagert sind, daß jeder Speicherscheibe ein Anschlag zugeordnet ist, der mit einem jeder benachbarten Scheibe zugeordneten Anschlag zur Differenzwinkel-Begrenzung zusammenwirkt, und daß wenigstens ein Teil der Anschläge elastisch ausgeführt ist.According to the invention this object is achieved in that the Storage disks can be rotated freely in fixed bearings are that a stop is assigned to each storage disk, the stop associated with each adjacent disc interacts to limit the difference angle, and that at least part of the stops is elastic.
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.
Wenigstens ein Teil der Anschläge ist elastisch federnd, also energiespeichernd, ausgeführt. Auch eine dämpfende Ausführung ist möglich. 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.At least some of the stops are resilient, so energy-saving, executed. Also a damping version is possible. In one embodiment, one stop can be used on each storage disc 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, that is curious; excited. Initially, this causes the Storage discs up to the washer, as well as the motor, which drives the washer, and then an acceleration the washer and the storage disks in the new direction of rotation regardless of the drive motor that this movement however supported. Because the drive motor during acceleration but is not fully loaded by the panes, it can accelerate very quickly, after which the disc and the drive motor through the storage disks over the stops again be burdened 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. On 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.

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
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
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-
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
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
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-
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. Des weiteren 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
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
Vorteilhaft bei der in den Fig. 1 und 2 dargestellten Vorrichtung
ist des weiteren, 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 furthermore that overturning the washer 5
and the
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
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
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
