Abstract

To form a round twisted electric cable, with wire cable components (1) twisted in both directions, static guides (9) for the wires (1) are in front of the twist holding zone (L). Guides (2,3), with a circular arc shape, apply a torque to the wires (1) which match the circular cross section of a round cable. The static guides (9) move the wires (1) into the angular lie at the twisting cable. The gap (L) between the twisting head (4) and the static guides (9) is a whole number multiple of the gap at the change points of the pitch direction at the finished cable, within a tolerance of 20%, and is longer than the length of the twist holding zone for winding the wires (1). The twisting of the wires (1) round their own axes is measured (7) shortly before the twisting head (4), in relation to the profiled guides (2,3), and the angular deviation is taken for correction of the pitch lengths.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer (Kabel-)Verseilung mit wechselnder Schlagrichtung aus Verseilelementen kreissektorförmiger Querschnittsform mit einem in wechselnder Drehrichtung angetriebenen Verseilkopf, der zum Aufbringen der Verdrehkräfte für die Verseilelemente an deren Querschnittsform angepaßte Führungen hat, und einem in Arbeitsrichtung vor dem Verseilkopf angeordneten, gestreckten Drallspeicher (Strecke L), der eine Anzahl von Schlägen (Umdrehungen) einer Drehrichtung der Verseilelemente speichert, wobei die Verseilelemente über ihre Elastizitätsgrenze (plastisch) verformt (verdreht) werden.The invention relates to a method for producing a (Cable) stranding with alternating lay direction from stranding elements Sector-shaped cross-sectional shape with an in changing direction of rotation driven stranding head, which for Application of the twisting forces for the stranding elements on their Cross-sectional shape adapted guides, and one in the working direction stretched in front of the stranding head Swirl accumulator (distance L), which a number of strokes (revolutions) a direction of rotation of the stranding elements, the stranding elements exceeding their elastic limit (plastic) be deformed (twisted).

Verfahren zum Verseilen mit wechselnder Schlagrichtung sind für runde Adern bekannt. Sektorförmige Verseilelemente (Drähte) müssen jedoch, anders als runde Drähte, wegen ihrer "Paßform" im Seil zusätzlich einmal pro Schlag (Umdrehung) um ihre Achse verdrillt werden (Verseilen ohne Rückdrehung). Das bedeutet, daß auf die einzelnen Verseilelemente (Drähte/Adern), bezogen auf deren Längsachsen, hohe Drehmomente aufgebracht werden müssen.Are procedures for stranding with alternating lay direction known for round veins. Sector-shaped stranding elements (wires) however, unlike round wires, because of their "fit" in the rope once per turn (turn) around her Axis are twisted (stranding without reverse rotation). That means, that on the individual stranding elements (wires / wires), based on their longitudinal axes, high torques applied Need to become.

Die EP-A1-0582802 beschreibt eine Verseilmaschine zum Verseilen mit wechselnder Schlagrichtung für Drähte mit runder Querschnittsform. Sie besteht aus einer feststehenden Einlaufführung in einen Drallspeicher und einem hin- und herrotierenden Legekopf mit Führungen für jeden Draht. Wenn die Drähte um ihre Achse verdrillt werden sollen, müssen sie im Legekopf drehfest gehalten werden. Es ist naheliegend, dafür formschlüssig der Drahtquerschnittsform angepaßte Führungen einzusetzen.EP-A1-0582802 describes a stranding machine for stranding with alternating lay direction for wires with a round cross-sectional shape. It consists of a fixed inlet guide in a swirl storage and a back and forth rotating Laying head with guides for each wire. If the wires around their axis are to be twisted, they must be in the laying head be held in a rotationally fixed manner. It is obvious, but positive use guides adapted to the wire cross-sectional shape.

Mit formschlüssigen Führungen im Verseilkopf kann zwar auf die einzelnen Drähte das erforderliche Torsionsmoment aufgebracht werden, wenn jedoch die sektorförmigen Leiter, mit z.B. 95 mm2 Querschnittsfläche, aus massivem Aluminium bestehen, haben diese nur sehr geringe Elastizität, so daß sie bereits in der Speicherstrecke (bei Anwendung praktikabler Schlagzahlen in einer Drehrichtung und praktikabler Länge der Speicherstrecke) hinsichtlich ihrer Verdrehung plastisch verformt werden.With positive guides in the stranding head, the required torsional moment can be applied to the individual wires, but if the sector-shaped conductors, e.g. with a cross-sectional area of 95 mm 2 , are made of solid aluminum, they have very little elasticity, so that they are already in the storage section ( when using practicable stroke numbers in one direction of rotation and practicable length of the storage section) are plastically deformed with regard to their rotation.

Sektorförmige Aluminium-Leiter mit Querschnitten von etwa 50 bis 240mm2 werden bei einer Drehung um 360° (1 Schlag) auf Längen unter 14m bis 30m bereits plastisch verformt. Die realen Schlaglängen betragen aber nur 0,8 bis 2m. Dies hat beim Starten der Verseilung bereits nach der ersten Drehrichtungsumkehr zur Folge, daß die Verdrehsteigung in den einzelnen Adern an jeder Stelle der Speicherstrecke wellenförmig unterschiedlich ist.Sector-shaped aluminum conductors with cross-sections of approximately 50 to 240mm 2 are already plastically deformed by turning through 360 ° (1 stroke) to lengths below 14m to 30m. The real lay lengths are only 0.8 to 2m. When starting the stranding, this already has the consequence after the first reversal of the direction of rotation that the twist pitch in the individual wires is undulating at every point of the storage path.

Diese Verdrehung ist im wesentlichen eine plastische Verformung und die Winkellage der Verseilelemente ändert sich daher ständig an jeder Stelle der Verseilelemente während ihres Laufes zur Verseilscheibe.This twist is essentially a plastic deformation and the angular position of the stranding elements therefore changes constantly at every point of the stranding elements during their Run to the stranding disc.

Aufgrund der plastischen Vorverformung der Verseilelemente (Adern) in der Speicherstrecke laufen die einzelnen Verseilelemente stellenweise sprunghaft wechselnd, mit großen torsionsmäßigen Versatz relativ zur Richtung der Führungen in den Verseilkopf ein, so daß deren Isolierung beschädigt werden kann. Mit einer formschlüssigen Rollenführung lassen sich durchlaufende Verseilelemente zwar nach der Rollenführung gut verdrillen - auf der Einlaufseite in die Führung erzeugt eine sprunghafte Steigungsänderung sehr leicht einen "Überschlag" in der Führung. Anderseits werden auch sektorförmige Verseilelemente verwendet, die aus Einzeldrähten verseilt und dann sektorförmig verformt wurden. Diese, wenn sie im unteren Querschnittsbereich liegen, bleiben im Drallspeicher im elastischen Bereich, so daß ihr Einlauf in die Verseilscheibe gleichmäßig erfolgt.Due to the plastic pre-deformation of the stranding elements The individual stranding elements run in the storage section in places abruptly changing, with large torsional Offset relative to the direction of the guides in the Stranding head so that their insulation is damaged can. With a form-fitting roller guide continuous stranding elements are good after the roller guide twist - on the inlet side into the guide creates one sudden change in incline very easily a "rollover" in the leadership. On the other hand, there are also sector-shaped stranding elements used that stranded from single wires and then were deformed in a sector shape. This if they are in the lower cross-sectional area lie, remain in the swirl storage in the elastic Area so that its entry into the stranding disc done evenly.

Die DE 3607443 A1 beschreibt eine SZ-Verseileinrichtung, bei der die Torsion der Verseilelemente durch eine besondere Ausführung des verseilnippels aufgebracht wird, und die Speicherrohrlänge so gewählt wird, daß sie wenigstens dem Abstand zwischen zwei Umkehrstellen entspricht. DE 3607443 A1 describes an SZ stranding device, at the torsion of the stranding elements through a special design of the stranding nipple is applied, and the length of the storage tube is chosen so that it is at least the distance between two reversal points.

Die DE 3607443 A1 beschreibt weiters einen Drallspeicher, bei dem ein zusätzlicher Verseilnippel auf der Einlaufseite und ein "Aufseilnippel" auf der Auslaufseite vorgesehen ist, so daß die Adern bereits in der Speicherstrecke formschlüssig miteinander verseilt werden, allerdings mit einer größeren Schlaglänge als am fertigen Seil.DE 3607443 A1 also describes a swirl accumulator, at an additional stranding nipple on the inlet side and a "rope nipple" is provided on the outlet side, so that the wires are already form-fitting in the storage section are stranded together, but with a larger one Lay length than on the finished rope.

Vergleicht man die eingangs genannten Schlaglängen, bei denen eindrähtige, große Aluminium-Leiter plastisch verdrillt werden (13 bis 30m), mit den üblichen, dafür vorgesehenen Schlaglängen (0,8 bis 2m), dann muß man davon ausgehen, daß dieses bekannte Verfahren nur für kleinere, aus Einzeldrähten verseilte Leiterseile vorgesehen ist, die so elastisch sind, daß im Drallspeicher kaum eine bleibende Verdrehung entsteht.If you compare the stroke lengths mentioned at the beginning solid, large aluminum conductors can be twisted plastically (13 to 30m), with the usual lay lengths (0.8 to 2m), then you have to assume that this known methods only for smaller, stranded from individual wires Conductor cables are provided which are so elastic that There is hardly any permanent twisting in the swirl storage.

Ziel dieser Erfindung ist es, ein Verfahren zur Verfügung zu stellen, bei dem auch steife, sektorförmige Verseilelemente (Adern) zum Zeitpunkt des Einlaufs in die sich hin- und herdrehende Verseilscheibe, relativ zur Scheibe in ihren formschlüssigen Führungen immer die richtige Winkellage haben (also mit der Spitze zum Zentrum der Verseilscheibe zeigen) und dadurch gleichmäßig einlaufen.The aim of this invention is to provide a method in which also stiff, sector-shaped stranding elements (Veins) at the time of entering the back and forth Stranding washer, relative to the washer in its form-fitting Guides always have the correct angular position (i.e. point to the center of the stranding disk) and shrink evenly.

Diese Aufgabe wird mit der Erfindung zunächst dadurch.gelöst, daß die vor dem Drallspeicher angeordneten, stationären Führungen für jedes Verseilelement ebenfalls an jedes Sektorprofil angepaßte kreissektorförmige Führungen zum Aufbringen eines Drehmoments auf die einzelnen Verseilelemente haben, wobei diese stationären Führungen die einzelnen Verseilelemente bereits in die dem Verseilverband (Kabel) entsprechende Winkellage bringen, und der Abstand zwischen der Verseilscheibe und den Führungen einem geradzahligen Vielfachen des Abstandes der Wendestellen am fertigen Verseilverband (Kabel) entspricht.This object is first achieved with the invention in that that the stationary guides arranged in front of the swirl storage for each stranding element also on each sector profile adapted circular sector-shaped guides for application a torque on the individual stranding elements, these stationary guides the individual stranding elements already in the corresponding to the stranding association (cable) Bring angular position, and the distance between the stranding disk and the guides an even multiple of the distance the turning points on the finished stranding (cable) equivalent.

Von Vorteil ist dabei, daß das freie Verdrehen der Verseilelemente (Adern) um ihre eigene Achse und damit ihre plastische Verformung auf dieser Strecke nicht behindert wird, z.B. durch formschlüssige Führungen im Drallspeicher. Ferner ist es vorteilhaft, wenn diese Abstände für alle Verseilelemente (Adern) gleich sind.The advantage here is that the free twisting of the stranding elements (Veins) around their own axis and thus their plastic Deformation is not hindered on this route, e.g. by form-fitting guides in the swirl storage. It is also advantageous if these distances for all stranding elements (wires) are the same.

Der Abstand der stationären Führungen bis zur Verseilscheibe ist mit Vorteil größer als die Länge des sogenannten Drallspeichers, der nur die Umschlingung der Verseilelemente (Adern) begrenzt, und in dem die Verseilelemente (Adern) sehr nahe zur Verseilachse geführt werden müssen. Die verdrehfesten Führungen können bereits weit vor dem Einlauf in den Drallspeicher, in der Nähe der Ablaufspulen angeordnet sein, also auch mit großem Abstand zur Verseilachse, weil sie nur die Verdrehung der Verseilelemente (Adern) um ihre eigene Achse beeinflussen sollen. Je größer der Abstand der stationären Führungen zu der Verseilscheibe ist, umso mehr Schläge einer Drehrichtung können ausgeführt werden.The distance from the stationary guides to the stranding disc is advantageously longer than the length of the so-called swirl accumulator, which only wraps around the stranding elements (Veins) limited, and in which the stranding elements (veins) very must be guided close to the stranding axis. The twist-proof Guides can be opened well before they enter the swirl be arranged in the vicinity of the payout spools, that is even at a great distance from the stranding axis, because they are only the Twisting of the stranding elements (wires) around their own axis should influence. The greater the distance of the stationary Guides to the stranding disc, the more blows one Direction of rotation can be carried out.

Zur genauen Feststellung der optimalen Einstellung (Schläge einer Richtung, Schlaglänge) kann auch (wie in Fig. 1 gezeigt), die relative Verdrehung der Verseilelemente (Adern) in der Nähe des Verseilkopfes gemessen und gegebenenfalls zur Feinkorrektur des Einstellverhältnisses verwendet werden.For precise determination of the optimal setting (blows one direction, lay length) can also (as shown in Fig. 1), the relative rotation of the stranding elements (wires) in measured near the stranding head and if necessary to Fine correction of the setting ratio can be used.

Bei im Drallspeicher im wesentlichen plastisch vorverdrehten Drähten soll das Längenverhältnis 2, 4, 6 möglichst genau eingehalten werden, am größten würde die Materialbeanspruchung bei Längenverhältnissen von 1, 3, 7 werden.When essentially pre-twisted in the swirl accumulator Wires should have the aspect ratio 2, 4, 6 as accurate as possible the material stress would be greatest with length ratios of 1, 3, 7.

    • Die Verseilelemente 1 laufen von nicht dargestellten Ablaufspulen zu stationären Führungen 9, welche die Verseilelemente, ähnlich wie im Verseilkopf 4 (Fig. 3) mit profilierten Rollen 2, 3 in der richtigen Winkellage halten. Im Abstand "L", welche in diesem Ausführungsbeispiel gleichzeitig der Länge des Drallspeichers entspricht, von den stationären Führungen 9 befindet sich ein Verseilkopf 4, der die Verseilelemente 1 mit abwechselnder Drehrichtung verseilt.The stranding elements 1 run from winding spools, not shown to stationary guides 9, which the stranding elements, similar to the stranding head 4 (Fig. 3) with profiled rollers Hold 2, 3 in the correct angular position. At a distance "L", which in this embodiment, the length of the Twist memory corresponds to the stationary guides 9 there is a stranding head 4, which the stranding elements 1 with twisted in alternating direction of rotation.

    Im Bereich des Drallspeichers, also zwischen den Führungen 9 und dem Verseilkopf 4 befindet sich eine frei mitlaufende (um eine Längsachse frei drehbare) Stützscheibe 8, deren Aderdurchführungen größer sind als der Durchmesser der Verseilelemente 1, so daß das freie Verdrillen der Verseilelemente 1 um sich selbst nicht behindert wird.In the area of the swirl accumulator, i.e. between the guides 9 and the stranding head 4 is a free running (um a longitudinal axis freely rotatable) support disc 8, the wire bushings are larger than the diameter of the stranding elements 1, so that the free twisting of the stranding elements 1 in order not to be handicapped.

    Die Stützscheibe 8, es können auch mehrere Stützscheiben vorgesehen sein, stellt den gestreckten Drallspeicher dar, und verhindert in bekannter Art ein Verknoten der Adern vor der Verseilscheibe (Verseilkopf) 4. Der Abstand L zwischen der stationären Führung 9 und dem Verseilkopf 4, die beide mit formschlüssig an den Verseilelementen 1 angreifenden, und im Ausführungsbeispiel als Rollen ausgebildeten Führungen 2, 3 ausgestattet sind, entspricht zweimal dem Abstand zweier Wendestellen am fertigen Verseilverband (Kabel), so daß die plastisch um ihre Achse verdrehten Verseilelemente 1 genau und ohne Verkanten in die Führungen 2, 3 des Verseilkopfes 4 einlaufen. Nach dem Verseilkopf 4, der mit Hilfe eines Motors 5 gedreht werden kann, laufen die Verseilelemente 1 zu einem Verseilnippel 6, in dem sie beispielsweise zu dessen in Fig. 2 gezeigten Verseilverband (Kabel) zusammengeführt werden.The support disc 8, several support discs can also be provided represents the stretched swirl accumulator, and prevents the veins from knotting in a known manner Stranding washer (stranding head) 4. The distance L between the stationary guide 9 and the stranding head 4, both with form-fitting attack on the stranding elements 1, and in Embodiment guides 2, 3 designed as rollers are equipped twice the distance between two turning points on the finished stranding (cable) so that the plastic about their axis twisted elements 1 exactly and run into the guides 2, 3 of the stranding head 4 without tilting. After the stranding head 4, which is 5 can be rotated, the stranding elements 1 run to one Stranding nipple 6, for example, to the one in FIG. 2 shown stranding association (cable) are brought together.

    In Fig. 1 ist noch eine vor dem Verseilkopf 4 angeordnete Einrichtung 7 dargestellt, an der mit frei drehbaren sektorförmigen Nippeln die tatsächliche Winkellage der Verseilelemente 1 auf bekannte Art durch elektrische Winkelgeber abgetastet werden kann.

    Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt dargestellt werden:In summary, an embodiment of the invention can be like are represented as follows:

    Ein Verfahren zum SZ-Verseilen kreissektorförmiger, elektrischer Adern (Verseilelemente) 1 zu einem runden Kabel arbeitet mit einem in abwechselnder Drehrichtung angetriebenen Verseilkopf (Verseilscheibe) 4 und mit stationären Führungen 9 für die einzelnen Adern 1, welche die Adern 1, ebenso wie im Verseilkopf 4, drehfest umfassen. Der Abstand L zwischen den stationären Führungen 9 und dem Verseilkopf 4 beträgt dabei ein geradzahliges Vielfaches des Abstandes zweier Drallwechselstellen am fertigen Verseilverband. Dadurch ist gewährleistet, daß auch steife, unelastische sektorförmige Adern, die bereits vor dem Einlaufen in den Verseilkopf 4 bleibend plastisch um ihre eigene Achse verdreht wurden, wieder in der richtigen Winkellage in die profilierten Führungen des Verseilkopfes 4 einlaufen.A method for SZ stranding circular sector-shaped, electrical Cores (stranding elements) 1 works to a round cable with one driven in alternating direction of rotation Stranding head (stranding disc) 4 and with stationary guides 9 for the individual wires 1, which the wires 1, as in Include stranding head 4, rotatably. The distance L between the stationary guides 9 and the stranding head 4 is an even multiple of the distance between two swirl change points on the finished stranding. This ensures that even stiff, inelastic sector-shaped veins, that remain before entering the stranding head 4 were plastically twisted around their own axis, again in the correct angular position in the profiled guides of the stranding head 4 break in.

Method for manufacturing a twisted cable formation with alternating direction of lay from twisting elements (1) of a circular sector-shaped cross-sectional shape, with a layplate (4) which is driven in alternating rotational directions and comprises guides (2, 3), adapted to the cross-sectional shape of the individual twisting elements, for applying the twisting forces for the latter, and with a straight twist store which is disposed before the layplate (4) in the working direction and which stores a large number of lays of a rotational direction of the twisting elements (1), wherein the twisting elements (1) are deformed beyond their elastic limit, characterised in that the stationary guides (9), disposed before the twist store, for the twisting elements (1) also have circular sector-shaped guides (2, 3), adapted to the circular sector-shaped cross-sectional shape of the latter, for applying a torque to the twisting elements (1), wherein the stationary guides (9) bring the twisting elements (1) into the angular position corresponding to the twisted formation, and wherein the spacing (L) between the layplate (4) and the stationary guides (9) corresponds to an even-numbered multiple within a tolerance of 20% of the spacing of the turning points of the direction of lay in the finished twisted formation.
    2. Method according to Claim 1, characterised in that the spacing (L) between the layplate (4) and the stationary guide (9) with the sector-shaped guides (2, 3) is greater than the length of the twist store for winding around the twisting elements (1).
    3. Method according to Claim 1 or 2, characterised in that the twist of the sector-shaped twisting elements (1) about their own axis is measured just before the layplate (4) - relative to the profiled guides (2, 3) thereof - and the angular deviation is used to correct the length of lay.
