Description

Die Erfindung betrifft eine Vorrichtung zum Abwickeln von Verseilgutspulen mit einem Überkopfabzug von der innerhalb eines im Querschnitt zylindrischen Topfes drehbar angeordneten, angetriebenen Verseilgutspule, wobei die Längsachsen von Spule und Topf in dieselbe Richtung weisen.The invention relates to a device for unwinding Stranded spools with an overhead take-off from inside of a pot with a cylindrical cross section, driven stranded material spool, the longitudinal axes of Point the coil and pot in the same direction.

Von der Verseilgutspule wird mit einer solchen Vorrichtung das Verseilgut abgewickelt und beispielsweise einer Verseilmaschine zur Weiterverarbeitung des Verseilgutes zugeführt.Such a device is used for the stranded material spool the stranded material is unwound and, for example, a stranding machine fed for further processing of the stranded material.

Vorrichtungen zum Abwickeln von Verseilgutspulen sind aus dem Stand der Technik bekannt. Dabei ist zwischen unterschiedlichen Typen von Abwickelvorrichtungen zu unterscheiden. Es sind beispielsweise Vorrichtungen zum Abwickeln mit quer zur Abzugsrichtung des Seiles angeordneter Rotationsachse der Verseilgutspule bekannt. Derartige Abwickelvorrichtungen werden jedoch durch die Erfindung nicht berührt.Devices for unwinding cords of twisted material are from the State of the art known. It is between different Distinguish types of unwinders. It are, for example, devices for unwinding across Pulling direction of the rope arranged axis of rotation Stranded spool known. Such unwinders are however not affected by the invention.

Bei einem gattungsgemäßen Typ von Abwickelvorrichtungen wird das Verseilgut stirnseitig der Spule abgezogen. Hier spricht man von einer Abwickelvorrichtung mit Überkopfabzug. Abwickelvorrichtungen mit Überkopfabzug können eine feststehende oder angetriebene Verseilgutspule besitzen. Eine Abwickelvorrichtung mit feststehender Verseilgutspule ist beispielsweise der Deutschen Offenlegungsschrift DE 3414396 zu entnehmen. Da die Verseilgutspule fest steht, ergibt sich beim Abziehen des Verseilgutes je volle Windung eine Drehung von 360°, die sogenannte Abzugstorsion. Diese insbesondere bei Überkopfabzügen auftretende Abzugstorsion kann zu unerwünschter Schlaufenbildung führen. Aus diesem Grund wurden Verfahren und Vorrichtungen entwickelt, die das Verseilgut entgegen der Abzugstorsion drehen, so daß die resultierende Torsion ständig möglichst bei Null liegt. Diese Kompensation der Abzugstorsion wird auch als Rückdrehung bezeichnet. In a generic type of unwinders the stranded material is pulled off the end of the spool. Here speaks one from an unwinding device with overhead take-off. Unwinding devices with overhead trigger can be a fixed or have a driven spool. An unwinder with a fixed strand spool is for example to German published application DE 3414396 remove. Since the stranded bobbin is fixed, it follows one turn per full turn when pulling off the stranded material of 360 °, the so-called withdrawal torsion. This in particular Trigger twist occurring with overhead deductions can become undesirable Lead loop formation. For this reason Processes and devices developed for the stranded material turn counter to the torsion so that the resulting Torsion is always zero if possible. This compensation the withdrawal torsion is also referred to as backward rotation.

Bei der Vorrichtung, die Ausgangspunkt der vorliegenden Erfindung ist, wird diese Rückdrehung durch die innerhalb eines im Querschnitt zylindrischen Topfes drehbar angeordnete, angetriebene Verseilgutspule erzeugt, von der das Verseilgut durch die Fliehkraft an die Innenmantelfläche des Topfes geschleudert und dort abgebremst wird. Die Oberflächenbeschaffenheit der Innenmantelfläche des Topfes und die Drehzahl der Verseilgutspule bestimmen die Zugkraft, die in dem abzuwikkelnden Verseilgut wirkt. Da mit steigender Drehzahl und Abzugsgeschwindigkeit die Zugkraft steigt, sind die der Abwickelvorrichtung nachgeschalteten Verarbeitungsstufen, insbesondere Verseilmaschinen, in ihrer Leistungsfähigkeit, d. h. in der pro Zeiteinheit maximal erzeugbaren Länge des zu erzeugenden Seiles begrenzt. Eine Leistungssteigerung durch Erhöhen der Drehzahl der Verseilgutspule ist wegen des damit verbundenen Risikos des Reißens des Verseilgutes nicht mehr möglich.In the device, the starting point of the present invention is this reverse rotation by the inside of a in the cross-section of cylindrical pot rotatably arranged, driven Stranded spool generated from which the stranded goods thrown against the inner surface of the pot by centrifugal force and is slowed down there. The surface texture the inner surface of the pot and the speed of the Stranded spools determine the tensile force in the one to be unwound Stranded material works. Because with increasing speed and take-off speed the tensile force increases, that of the unwinder downstream processing stages, in particular Stranding machines, in their performance, d. H. in the maximum length that can be generated per unit of time generating rope limited. A performance increase through Increasing the speed of the stranded material spool is because of this associated risk of tearing the stranded material no longer possible.

Aus der DT 25 08 896 A1 ist bereits ein Drahtabgabeapparat bekannt, der eine auf einem Spulenträger angeordnete, motorisch angetriebene Spule aufweist. Ein zylindrisches Antiballonorgan ist koaxial zur Spule fest an dem Rahmen des Drahtabgabeapparates befestigt, um den Radius der von der Spule abgezogenen Drahtschleife zu begrenzen. In einer Ausgestaltung des Drahtabgabeapparates ist zur Verminderung der Reibung der abgezogenen Drahtschleife am Antiballonorgan dieses letztere gemeinsam mit der Spule auf einer Welle drehbar.DT 25 08 896 A1 already has a wire dispenser known, the one arranged on a bobbin, motorized has driven coil. A cylindrical antiballoon organ is coaxial to the coil on the frame of the Wire dispenser attached to the radius of the Limit coil detached wire loop. In one embodiment of the wire dispenser is to reduce the Friction of the stripped wire loop on the antiballoon organ the latter can be rotated together with the coil on a shaft.

Der Erfindung liegt ausgehend von diesem Stand der Technik die Aufgabe zugrunde, eine Vorrichtung zum Abwickeln von Verseilgutspulen zu schaffen, die noch höhere Abzugsgeschwindigkeiten erlaubt und eine stufenlose Einstellung bzw. Regelung der Zugkraft in dem Verseilgut ermöglicht, um die Produktionsleistung in nachgeschalteten Verarbeitungsstufen, insbesondere Verseilmaschinen, zu steigern. The invention is based on this prior art the task of a device for unwinding To create stranded spools that have even higher take-off speeds allowed and a stepless adjustment or regulation the tensile force in the stranded goods enables to the production output in downstream processing stages, especially stranding machines.

Die Lösung dieser Aufgabe basiert auf dem Gedanken, die aufgrund des Topfes ausgeübte Bremswirkung auf das Verseilgut in Abhängigkeit der Drehzahl der Verseilgutspule ändern zu können.The solution to this task is based on the thought that arises braking effect on the stranded material in the pot To be able to change the speed of the twisted material spool.

Im einzelnen wird diese Aufgabe dadurch gelöst, daß der Topf unabhängig von der Verseilgutspule um seine Längsachse drehbar ist, daß Spule und Topf eine gemeinsame Längsachse besitzen und der Topf ebenfalls mit einem Antrieb verbunden ist, wobei die Drehzahlen der Antriebe für Spule und Topf unabhängig voneinander einstellbar sind.In particular, this problem is solved in that the pot can be rotated about its longitudinal axis independently of the stranded bobbin is that the coil and pot have a common longitudinal axis and the pot is also connected to a drive is, the speeds of the drives for the coil and pot independent are adjustable from each other.

Durch die Anordnung des Topfes gemäß den Merkmalen des Anspruchs 1 ist eine besonders genaue, insbesondere stufenlose Einstellung bzw. Regelung der Zugkraft in dem Verseilgut in Abhängigkeit von der Abzugsgeschwindigkeit möglich. Durch die freie Vorgabe der Drehzahlen von Spule und Topf lassen sich beliebige Relativgeschwindigkeiten zwischen Spule und Topf, innerhalb der maximal zulässigen Höchstgeschwindigkeiten für Spule und Topf, einstellen. Infolge dessen läßt sich die Bremswirkung und damit die Zugkraft, die in dem Verseilgut wirkt, in weiten Grenzen verändern.By arranging the pot according to the features of the claim 1 is a particularly precise, in particular stepless Setting or regulating the tensile force in the stranded material in Depending on the take-off speed possible. Through the The speed of the spool and pot can be freely specified any relative speeds between coil and pot, within the maximum allowable speeds for Adjust the coil and pot. As a result, the Braking effect and thus the tensile force in the stranded material works, change within wide limits.

Um ein Reißen oder Schlaufenbildung des Verseilgutes zu vermeiden, drehen sich Spule und Topf gleichsinnig und ist die Drehzahl der Spule größer oder höchstens gleich der Drehzahl des Topfes.To avoid tearing or looping of the stranded material, spool and pot rotate in the same direction and is the Speed of the coil greater than or at most equal to the speed of the pot.

Das von der Verseilgutspule abgezogene Verseilgut wird in üblicher Weise durch eine hohle Aufnahmeachse für die Verseilgutspule zu einer Bremse geführt, die drehbar gelagert ist. Über die Bremse kann die in dem Verseilgut wirkende Zugkraft genau eingestellt werden. Um nicht als Torsionssperre für die Rückdrehung des Verseilgutes zu wirken, ist die Bremse drehbar gelagert. The stranded material drawn off from the stranded spool becomes more common Way through a hollow receiving axis for the stranded material spool led to a brake that is rotatably mounted. The tensile force acting in the stranded material can be applied via the brake can be set precisely. In order not to act as a torsion lock for the The brake can be rotated to reverse the twist stored.

In weiterer vorteilhafter Ausgestaltung der Erfindung nimmt der Querschnitt des Topfes vom Antrieb bis zu seiner offenen Stirnseite insbesondere kontinuierlich zu.In a further advantageous embodiment of the invention takes the cross section of the pot from the drive to its open End face in particular continuously.

Nachfolgend wird die Erfindung anhand einer schematischen Zeichnung der Vorrichtung zum Abwickeln von Verseilgutspulen näher erläutert.The invention is based on a schematic Drawing of the device for the unwinding of stranded material spools explained in more detail.

Die erfindungsgemäße Vorrichtung zum Abwickeln von Verseilgutspulen, nachfolgend kurz Abwickelvorrichtung genannt, wird insgesamt mit (1) bezeichnet. Sie besteht im wesentlichen aus einer Verseilgutspule (2) mit zwei Spulenwangen (10a, 10b), die drehbar in einem im Querschnitt zylindrischen Topf (3) angeordnet ist. Der Verseilgutspule (2) ist ein Spulenantrieb (4), dem Topf (3) ein Topfantrieb (5) zugeordnet.The device according to the invention for unwinding cords of twisted goods, hereinafter referred to as unwinding device overall designated (1). It essentially consists of a stranded bobbin (2) with two bobbin webs (10a, 10b), which are rotatable in a pot with a cylindrical cross-section (3) is arranged. The stranded material spool (2) is a spool drive (4), the pot (3) is assigned a pot drive (5).

Die Abwickelvorrichtung (1) besitzt darüber hinaus eine an sich bekannte Bremse (6).The unwinding device (1) also has one known brake (6).

Der Topf (3) ist an der den Antrieben zugewandten Stirnseite mit einem Flanschdeckel (7) verschraubt. Der Querschnitt des Topfes (3) nimmt vom Flanschdeckel (7) zunächst kontinuierlich zu und läuft in einem zylindrischen Teilstück (9) bis zur offenen Stirnseite (8) hin aus. Über die offene Stirnseite (8) wird die Verseilgutspule (2) auf eine Aufnahmeachse (11) aufgeschoben und deren Spulenwangen (10a, 10b) zwischen zwei Pinolen (12), (13) arretiert, wobei die Pinole (12) mit einem Deckel (14), der anschließend auf die Aufnahmeachse (11) aufgeschoben wird, verbunden ist.The pot (3) is on the front side facing the drives screwed to a flange cover (7). The cross section of the Pot (3) initially takes off from the flange cover (7) continuously to and runs in a cylindrical section (9) to towards the open end (8). Over the open front (8) the stranded material spool (2) on a take-up axis (11) pushed on and their coil cheeks (10a, 10b) between two quills (12), (13) locked, the quill (12) with a cover (14), which is then on the receiving axis (11) is postponed, connected.

Die Aufnahmeachse (11) besitzt einen Durchgang (15) für das von der Verseilgutspule (2) abgezogene Verseilgut. The receiving axis (11) has a passage (15) for the stranded material pulled from the stranded spool (2).

Die Bremse (6) besteht im einzelnen aus Drehlagern (16), (17), Führungsrollen für das Verseilgut (18), (19) sowie der eigentlichen Bremsanordnung (21).The brake (6) consists in particular of pivot bearings (16), (17), guide rollers for the stranded material (18), (19) and the actual brake assembly (21).

Sowohl der Topf (3) als auch die Spule (2) sind um ihre Rotationsachse (22) drehbar gelagert und werden durch den Topfantrieb (5) bzw. Spulenantrieb (4) in Drehung versetzt. Topf (3) und Spule (2) rotieren somit um die gleiche Achse (22), wobei sowohl die Drehzahl der Spule als auch die Drehzahl des Topfes mit in der Zeichnung nicht näher dargestellten, an sich bekannten Steuerungen frei wählbar sind. Hierdurch lassen sich zwischen Spule (2) und Topf (3) beliebige Relativgeschwindigkeiten einstellen und damit die Bremswirkungen auf das von der Spule (2) in Richtung des Innenmantels (23) abgeschleuderte Verseilgut und damit die Zugkraft in dem Verseilgut beeinflussen. Das an dem Innenmantel (23) zur offenen Stirnseite (8) geführte Verseilgut wird von dort in Richtung der Rotationsachse (22) durch den Durchgang (15), die Antriebe (5), (4) sowie die Bremse (6) geführt.Both the pot (3) and the coil (2) are about their axis of rotation (22) rotatably and are driven by the pot drive (5) or coil drive (4) set in rotation. pot (3) and coil (2) thus rotate about the same axis (22), where both the speed of the coil and the speed of the Pot with not shown in the drawing known controls are freely selectable. Let her through any relative speeds between the coil (2) and the pot (3) adjust and thus the braking effects that spun off from the coil (2) in the direction of the inner jacket (23) Stranded goods and thus the tensile force in the stranded goods influence. The open on the inner jacket (23) The end face (8) of the stranded material is guided from there towards the axis of rotation (22) through the passage (15), the drives (5), (4) and the brake (6) out.

Mit der Bremse (6) läßt sich schließlich die auf das Verseilgut wirkende Zugkraft gezielt einstellen, bevor dieses in einem nachgeschalteten Verarbeitungsprozeß, beispielsweise in einer in der Zeichnung nicht dargestellten Verseilmaschine weiterverarbeitet wird.With the brake (6) can finally on the stranded material Adjust the effective tractive force before this in one downstream processing, for example in a stranding machine, not shown in the drawing is processed further.

Je nach Anzahl der Einzelstränge, die in der Verseilmaschine zu einem Seil verarbeitet werden sollen, sind eine entsprechende Anzahl von Abwickelvorrichtungen (1) vorzusehen, um die Leistungsfähigkeit der nachgeschalteten Verseilmaschine nicht zu beeinträchtigen.Depending on the number of individual strands in the stranding machine are to be processed into a rope, are a corresponding Number of unwinders (1) to provide the performance of the downstream stranding machine not to interfere.

Durch die verblüffend einfache, erfindungsgemäße Maßnahme läßt sich bei einer Vorrichtung zum Abwickeln von Verseilgutspulen mit einem Überkopfabzug und Rückdrehung des Verseilgutes die in dem Verseilgut wirkende Zugkraft reduzieren. Due to the amazingly simple measure according to the invention can be used in a device for unwinding cords with an overhead deduction and reverse rotation of the stranded material reduce the tensile force acting in the stranded material.

Die reduzierte Zugkraft erlaubt höhere Abzugsgeschwindigkeiten und bringt damit eine höhere Produktivität nachgeschalteter Abläufe mit sich.The reduced traction allows higher take-off speeds and brings a higher productivity downstream Processes with themselves.

Selbstverständlich bezieht sich der Begriff Verseilgut, wie er in der vorstehenden Beschreibung verwendet wurde, nicht nur auf Seile im eigentlichen Sinne, sondern auch auf elektrische Kabel, Lichtleitkabel oder dergleichen. Der Begriff Einzelstrang umfaßt das Verseilgut, das jeweils von einer Verseilgutspule zu einer nachgeschalteten Verarbeitungsstufe, beispielsweise einem Verseilpunkt geführt wird. Auch der Einzelstrang kann wiederum aus mehreren Einzeldrähten, Einzelfasern, Litzen oder dergleichen bestehen.Of course, the term stranded material refers to how it was not used in the above description only on ropes in the strict sense, but also on electrical ones Cables, light guide cables or the like. The term Single strand comprises the stranded material, each of one Stranded bobbin to a downstream processing stage, for example, a stranding point is performed. Even the single strand can in turn consist of several individual wires, single fibers, Strands or the like exist.
