Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen einer Kabelverseilung mit
wechselnder Schlagrichtung (SZ-Verseilung) gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for producing a cable stranding
changing direction of lay (SZ stranding) according to the preamble of
Bei der reversierenden oder SZ-Verseilung, bei welcher die Schlagrichtung der Verseilelemente in Abständen wechselt, werden im Unterschied zu den Verseilverfahren mit gleichbleibender Schlagrichtung keine rotierenden Körbe für die Verseilelemente benötigt. Diese rotierenden Spulenabläufe lassen im allgemeinen nur eine begrenzte Länge für das herzustellende Verseilgut zu. Die SZ-Verseilung erlaubt demgegenüber eine kontinuierliche Fertigung mit hohen Abzugsgeschwindigkeiten. Die Verseilelemente durchlaufen hierbei eine Verseilstrecke, welche durch eine im allgemeinen feste Einlaufführung und eine in wechselnder Richtung drehbare Verseilscheibe begrenzt ist. Um ein Verheddern der Verseilelemente innerhalb der Verseilstrecke zu verhindern, werden zwischen der Einlaufführung und der Verseilscheibe für gewöhnlich Halteelemente bzw. Speicherscheiben angebracht, die Durchgangslöcher zur Führung der Verseilelemente aufweisen. Die Erfindung bezieht sich auf den Antrieb ebendieser Speicherscheiben.In the case of reversing or SZ stranding, in which the direction of lay of the In contrast to the stranding method, stranding elements are changed at intervals constant lay direction no rotating baskets required for the stranding elements. These rotating spools generally leave only a limited length for that stranded goods to be produced. SZ stranding, on the other hand, allows continuous Manufacturing with high take-off speeds. The stranding elements pass through one Stranding line, which is characterized by a generally fixed inlet guide and a alternating direction rotatable stranding disk is limited. To tangle the To prevent stranding elements within the stranding path, are between the Inlet guide and the stranding disk for usually holding elements or storage disks attached, which have through holes for guiding the stranding elements. The invention refers to the drive of these storage disks.
Aus der EP 0 932 165 A1 und der EP 0 767 965 B1 sind Vorrichtungen bekannt, bei denen der Antrieb der Speicherscheiben über eine drehelastische Verbindung erfolgt. Dafür wird ein Torsionselement verwendet, welches im Bereich der Einlaufführung fixiert ist und im Bereich der Verseilscheibe in wechselnder Richtung angetrieben wird. Während bei der EP 0 932 165 A1 die Verseilscheibe und die Speicherscheiben unmittelbar drehfest auf dem Torsionselement aufgebracht sind, liegt bei der EP 0 767 965 B1 das Torsionselement parallel beabstandet zu der Drehachse der Verseil- und Speicherscheiben. Hier erfolgt der Antrieb mittels eigener auf dem Torsionselement fixierter und an die Verseil- bzw. Speicherscheiben angreifender Übertragungsglieder. Bei beiden Ausführungen werden die Speicherscheiben mit unterschiedlichen Drehgeschwindigkeiten beaufschlagt, die mit zunehmenden Abstand von der Verseilscheibe geringer werden. Dadurch kann ein Verheddern der Verseilelemente in der Verseilstrecke bestmöglich verhindert werden.Devices are known from EP 0 932 165 A1 and EP 0 767 965 B1 in which the storage disks are driven via a torsionally elastic connection. For this purpose, a torsion element is used, which is fixed in the area of the inlet guide and is driven in alternating directions in the area of the stranding disk. While in EP 0 932 165 A1 the stranding disk and the storage disks are directly attached to the torsion element in a rotationally fixed manner, in EP 0 767 965 B1 the torsion element is spaced parallel to the axis of rotation of the stranding and storage disks. Here the drive is carried out by means of separate transmission elements fixed on the torsion element and acting on the stranding or storage disks. In both versions, the storage disks are subjected to different speeds of rotation, which decrease as the distance from the stranding disk increases. Tangling of the stranding elements in the stranding section can thereby be prevented as best as possible.
Den oben genannte Ausführungsformen ist allerdings die Schwierigkeit gemeinsam, die Drehzahl der einzelnen Speicherscheiben mit der erforderlichen Genauigkeit einzustellen. Zu diesem Zweck wurde unter anderem der Ansatz verfolgt, die Torsionselemente mit über die Lauflänge variablen Elastizitätsmodulen auszuführen, um so eine genauere Kontrolle über die lokale Drehgeschwindigkeit zu ermöglichen. Bei größeren Drehzahlen, wie sie bei der SZ-Verseilung auftreten können, ist dies aber nicht mehr möglich, da hier Massenträgheitseffekte innerhalb des Torsionselementes eine zunehmend wichtige Rolle spielen. Bei Umkehr der Antriebsrichtung im Bereich der Verseilscheibe ist es so durchaus möglich, daß einzelne Speicherscheiben ihre alte Drehrichtung für kurze Zeit beibehalten. Dies führt zu einem unkontrollierten und unerwünschten Phasenversatz der Speicherscheiben, wodurch die Höhe der möglichen Verseilgeschwindigkeiten begrenzt wird.However, the above-mentioned embodiments have in common the difficulty that Set the speed of the individual storage disks with the required accuracy. To To this end, the approach was followed, among other things, of the torsion elements Run length variable elasticity modules so as to have more precise control over the to allow local rotation speed. At higher speeds, as with SZ stranding this can no longer occur because of inertia effects play an increasingly important role within the torsion element. When reversing the Driving direction in the area of the stranding disk, it is quite possible that individual Storage disks maintain their old direction of rotation for a short time. This leads to one uncontrolled and undesirable phase shift of the storage disks, causing the height the possible stranding speeds is limited.
Der Erfindung liegt die Aufgabe zugrunde, erwähnte Nachteile zu vermeiden und eine Vorrichtung der eingangs erwähnten Art anzugeben, die die Vorteile des Antriebs der Speicherscheiben über ein Torsionselement aufweist und gleichzeitig eine möglichst genaue Kontrolle der Drehzahlen der einzelnen Speicherscheiben ermöglicht.The invention has for its object to avoid mentioned disadvantages and a Specify device of the type mentioned, the advantages of driving the Has storage disks over a torsion element and at the same time as accurate as possible Control of the speeds of the individual storage disks.
Erfindungsgemäß wird dies dadurch erreicht, daß das Torsionselement an mehreren Stellen mit unterschiedlichen Drehzahlen angetrieben ist.According to the invention this is achieved in that the torsion element in several places is driven at different speeds.
Durch diese Maßnahme wird erreicht, daß das zum Antrieb benötigte Drehmoment an unterschiedlichen Stellen des Torsionselements aufgetragen werden kann. Durch die Verwendung eines Torsionselements, welches für sich bereits als Übersetzungsgetriebe für die einzelnen Speicherscheiben wirkt, bleiben die aufzubringenden Korrekturen der Drehmomente sehr klein. Somit sind lediglich geringe zusätzliche Einzeldrehmomente erforderlich, die es aber ermöglichen, die oben erwähnten Nachteile, welche sich ergeben, wenn nur ein einziger Antrieb im Bereich der Verseilscheibe vorgesehen ist, bestmöglich zu vermeiden und höhere Verseilgeschwindigkeiten zu erreichen.This measure ensures that the torque required for the drive different places of the torsion element can be applied. Through the Use of a torsion element, which is already used as a transmission gear for the individual storage disks are effective, the corrections to be applied remain Torques are very small. Thus there are only small additional individual torques required, but which make it possible to overcome the disadvantages mentioned above which arise if only a single drive is provided in the area of the stranding disc, close as possible avoid and achieve higher stranding speeds.
Bei Verseilmaschinen, bei denen hohe Verseilkräfte für das verseilte Gut erforderlich sind, kann eine vorteilhafte Ausführungsform der Erfindung darin bestehen, daß an zumindest zwei Stellen des Torsionselementes eigene Antriebseinheiten vorgesehen sind.For stranding machines where high stranding forces are required for the stranded goods, An advantageous embodiment of the invention can consist in that at least two Places of the torsion element own drive units are provided.
Andererseits ist es bei leichtem Verseilgut zweckmäßig, daß nur ein Hauptantrieb mit Getriebe vorgesehen ist, welches mehrere Abtriebe aufweist, die mit den Torsionelementen drehfest verbunden sind.On the other hand, it is useful for light stranded material that only one main drive Gearbox is provided, which has a plurality of outputs, with the torsion elements are non-rotatably connected.
Um eine größtmögliche Flexibilität, verbunden z.B. mit dem Austausch des Torsionselementes, zu erreichen, kann vorgesehen sein, daß das Torsionselement beabstandet parallel zur Längsachse der Verseilstrecke geführt ist und die Speicherscheiben mittels Übertragungsglieder angetrieben sind. For the greatest possible flexibility, combined e.g. with the exchange of the To achieve torsion element, it can be provided that the torsion element is spaced apart is guided parallel to the longitudinal axis of the stranding line and the storage disks by means of Transmission elements are driven.
Kompaktere Bauformen können hingegen dadurch erreicht werden, daß das Torsionselement zentral in der Längsachse der Verseilstrecke geführt ist und die Speicherscheiben unmittelbar auf dem Torsionselement verdrehsicher angeordnet sind.On the other hand, more compact designs can be achieved in that the torsion element is guided centrally in the longitudinal axis of the stranding line and the storage disks directly are arranged on the torsion element against rotation.
In diesem Fall kann vorgesehen sein, daß der Antrieb des Torsionselementes direkt über die Speicherscheiben erfolgt. Damit ist es nicht notwendig, eigene Antriebsscheiben zusätzlich zu den ohnedies vorhandenen Speicherscheiben vorzusehen.In this case it can be provided that the drive of the torsion element directly over the Storage disks are done. It is therefore not necessary to add your own drive pulleys to provide the storage disks that are already present.
Um eine genauere Kontrolle über die Drehgeschwindigkeit der einzelnen Speicherscheiben zu ermöglichen, kann vorgesehen sein, daß das Torsionelement ein über seine Länge variables Elastizitätsmodul aufweist.To have more precise control over the speed of rotation of the individual storage disks enable, it can be provided that the torsion element is variable over its length Has modulus of elasticity.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung, durch die die Querschwingungsneigung des Torsionselements deutlich verringert wird, kann vorgesehen sein, daß das Torsionelement durch zumindest zwei, vorzugsweise vier, parallel zueinander verlaufende Einzelstäbe gebildet ist.According to a further advantageous embodiment of the invention, by which Transverse vibration tendency of the torsion element is significantly reduced can be provided be that the torsion element by at least two, preferably four, parallel to each other extending individual rods is formed.

antreibende Treibscheibe 7 verbunden sein, die ihrerseits ebenfalls drehfest mit dem

Treibscheiben 7 sind drehfest mit dem Torsionselement 15 verbunden.The
Dabei kann bei allen mit dem Torsionselement 15 gekoppelten Treibscheiben 7 mit den
zugehörigen Speicherscheiben 4 bzw. mit der Verseilscheibe 6 eine gleiche Übersetzung
vorgesehen sein.In this case, all of the
Durch die Verwendung des im Bereich der Führung 1 fixierten Torsionselements wird
gewährleistet, daß die Speicherscheiben 4 mit unterschiedlichen, mit zunehmenden Abstand
von der Verseilscheibe geringer werdenden Drehzahlen beaufschlagt werden.By using the torsion element fixed in the area of the
Darüberhinaus kann vorgesehen sein, die Speicherscheiben 4 nicht über ein einzelnes,
sondern über mehrere voneinander unabhängige oder auch miteinander gekoppelte
Torsionselemente 15 anzutreiben. Auf diese Weise können z.B. mehrere Torsionselemente 15
hintereinander in der Längsachse der Verseilstrecke vorgesehen sein.In addition, it can be provided that the
Die benötigten Korrekturen der Drehmomente werden in Fig. 1 an mehreren Stellen des
Torsionselements 15 über eigene Antriebseinheiten aufgetragen. Diese umfassen
Antriebsscheiben 14, die jeweils über einen Riemen 9' mit entsprechenden Treibscheiben 7'

Genauso ist es auch möglich, die einzelnen Drehmomente über ein mit einem einzigen
Hauptantrieb verbundenes Getriebe aufzubringen, welches mehrere Abtriebe aufweist, die mit
den Antriebsscheiben 14 des Torsionselements 15 verbunden sind.In the same way, it is also possible to use individual torques with one

In Fig.2 ist eine Ausführungsform dargestellt, bei der das Torsionselement 15 zentral in der
Längsachse der Verseilstrecke geführt ist und die Speicherscheiben 4 unmittelbar
verdrehsicher auf dem Torsionselement 15 angebracht sind. In diesem Fall wird das
Torsionselement 15 mittels Riemen 9 direkt über die Speicherscheiben 4 angetrieben. Dies
kann auch bei der Ausführungsform gemäß Fig. 1 vorgesehen sein. So ist es z.B. auch mit
