Abstract

The spool holder shaft (A) has openings in each contg. a tube (C) which presses air-filled strips (B) outwards. The strips (B) act upon an inner ring belonging to the crowns and are firmly fixed to the shaft (A). One or more crowns have each an inner ring with its other surface eccentric. The ring, while turning, presses the tie-pieces of the crowns into one or another direction over the top edge.

Description

Die Erfindung betrifft eine Spulenhalterwelle zum Wickeln von Spulen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bobbin holder shaft for winding bobbins according to the preamble of claim 1.

Eine solche Spulenhalterwelle ist aus der US-A 4 767 077 bekannt. Dort wird jede zu wickelnde Spule über wenigstens drei Klemmeinrichtungen fixiert, von denen jede als geschlitzter Ring ausgebildet ist, der jedoch keine geometrisch einwandfreie Klemmhalterung der Spulen gewährleistet, weil er den Spulenkern über den Umfang mit unterschiedlicher Kraft klemmt. Das hat zur Folge, daß bei Spannungsungleichheiten kein einwandfreier Schlupf für den Spulenkern gewährleistet ist. Jedem Ring ist eine Gruppe von Andruckelementen zugeordnet, was der Forderung nach einer gleichmäßigen Spannkraftverteilung und einer einfachen Konstruktion und Montage zuwiderläuft. Entsprechendes gilt für die Maßnahme, alle Andruckelemente durch einen zentralen, expandierbaren Druckschlauch radial nach außen zu drücken. Um eine gleichmäßige Spannkraftverteilung zu gewährleisten, muß ein sehr stabiler Druckschlauch vorgesehen sein, über den ein erheblicher Druck aufzubringen ist.Such a coil holder shaft is known from US-A 4 767 077. There, each coil to be wound is fixed by at least three clamping devices, each of which is designed as a slotted ring, which, however, does not guarantee a geometrically perfect clamping holder for the coils because it clamps the coil core over the circumference with different forces. As a result, perfect slippage for the coil core is not guaranteed in the event of voltage inequalities. A group of pressure elements is assigned to each ring, which runs counter to the requirement for an even distribution of the clamping force and simple construction and assembly. The same applies to the measure to press all pressure elements radially outwards through a central, expandable pressure hose. In order to ensure a uniform distribution of the clamping force, a very stable pressure hose must be provided, through which a considerable pressure can be applied.

Aus der DE-A 35 19 380 ist eine Wickelwelle bekannt, die gleichmäßig am Außenumfang angeordnete, in Ausnehmungen radial geführte Andruckleisten hat, denen zur Radialverschiebung nach außen jeweils ein expandierbarer Druckschlauch zugeordnet ist. Die Druckschläuche drücken die Andruckleisten unmittelbar gegen die Bohrungsfläche der zu wickelnden Spulen, so daß beim Wickeln eine drehfeste und nicht veränderbare Verbindung zwischen den Spulen und der Wickelwelle hergestellt ist. Eine Anpassung der einzelnen Spulen an unterschiedliche Betriebsbedingungen, beispielsweise bei Änderungen der Zugspannungen an den einzelnen Spulen, ist nicht möglich. Vielmehr drehen sich alle Spulen ohne die Möglichkeit eines Schlupfes mit derselben Rotationsgeschwindigkeit wie die Wickelwelle.From DE-A 35 19 380 a winding shaft is known which has pressure bars arranged uniformly on the outer circumference and guided radially in recesses, each of which is assigned an expandable pressure hose for radial displacement to the outside. The pressure hoses press the pressure bars directly against the bore surface of the coils to be wound, so that a non-rotatable and unchangeable connection between the Coils and the winding shaft is made. It is not possible to adapt the individual coils to different operating conditions, for example when the tensile stresses on the individual coils change. Rather, all the coils rotate without the possibility of slipping at the same rotational speed as the winding shaft.

Schließlich ist in der GB-A 2 054 677 eine Wickelvorrichtung beschrieben und dargestellt, die bei jedem Wickelvorgang nur eine einzige Spule aufnimmt. Die Vorrichtung hat radial verschiebbare Klemmelemente, die sich jedoch an ihren Rändern gegenseitig abstützen und dadurch geführt werden, daß Kugeln in einem Käfig untergebracht sind.Finally, a winding device is described and shown in GB-A 2 054 677, which takes up only a single coil during each winding process. The device has radially displaceable clamping elements, which are mutually supported at their edges and are guided in that balls are accommodated in a cage.

Mit der Erfindung soll die Aufgabe gelöst werden, eine Spulenhalterwelle zur Verfügung zu stellen, bei der mit konstruktiv einfachen Mitteln eine gleichmäßige Druckkraftverteilung auf die festzuklemmenden Spulen ausgeübt wird.The object of the invention is to provide a bobbin holder shaft in which a uniform distribution of pressure force is exerted on the bobbins to be clamped using structurally simple means.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den abhängigen Patentansprüchen und aus der folgenden Beschreibung eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist. Es zeigen:

  • Figur 1 eine Ansicht der Spulenhalterwelle nach der Erfindung,
  • Figur 2 in vergrößertem Maßstab einen Querschnitt durch die Welle der Figur 1,
  • Figur 3 einen Querschnitt durch einen auf die Welle aufschiebbaren Ring für die Fixierung einer zu wickelnden Spule, die nicht dargestellt ist, und
  • Figur 4 eine Ansicht des Ringes der Figur 3.
Further features and advantages of the invention emerge from the dependent patent claims and from the following description of an exemplary embodiment which is illustrated in the drawing. Show it:
  • FIG. 1 shows a view of the coil holder shaft according to the invention,
  • FIG. 2 shows, on an enlarged scale, a cross section through the shaft of FIG. 1,
  • 3 shows a cross section through a ring which can be pushed onto the shaft for fixing a coil to be wound, which is not shown, and
  • Figure 4 is a view of the ring of Figure 3.

An einer mittleren Welle wurden drei Öffnungen angebracht, in die drei Schläuche gesetzt werden, die, wenn sie mit Luft gefüllt werden, drei Leisten nach außen drücken. Die Länge der Öffnungen und der Leisten bestimmt die Nutzlänge der Welle an der Spulenhalterkränze angebracht sind. Wenn die Welle zu drehen beginnt, drücken die von den mit Pressluft gefüllten Schläuchen ausgedehnten Leisten auf den Kranz, der mit einem internen Ring ausgestattet ist, dessen andere Oberfläche exzentrisch ist. Die Drehung dieses exzentrischen Ringes zwingt einige Plastikelemente, die von Kugeln gedrückt werden, sich über die äußere Kante des Kranzes anzuheben; diese Plastikelemente wirken immer wieder auf die Spule ein und zwingen sie, sich zu drehen, da sie durch den Kranz fest mit der Welle verbunden ist.Three openings were made on a central shaft, into which three hoses are placed, which, when filled with air, push three strips outwards. The length of the openings and the strips determines the useful length of the shaft on which the coil holder rings are attached. When the shaft begins to turn, the ledges, expanded by the hoses filled with compressed air, press on the ring, which is equipped with an internal ring, the other surface of which is eccentric. The rotation of this eccentric ring forces some plastic elements, which are pressed by balls, to rise above the outer edge of the ring; these plastic elements repeatedly act on the spool and force it to rotate, since it is firmly connected to the shaft by the ring.

Die Plastikleisten können am inneren Ring des Kranzes verlaufen; daraus ergibt sich, daß die Drehgeschwindigkeit des Kranzes und folglich der mit ihm fest verbundenen Spule, abnimmt und die Wicklung dieser Spule an die der anderen anpasst.The plastic strips can run on the inner ring of the wreath; this means that the speed of rotation of the ring and consequently of the coil firmly connected to it decreases and the winding of this coil adapts to that of the others.

Die Reibung der Plastikleisten am Kranz kann durch Erhöhung bzw. Minderung den Drucks in den Luftsäcken verstellt werden.The friction of the plastic strips on the rim can be adjusted by increasing or decreasing the pressure in the air bags.

Die Ausdehnung der Plastikelemente über die äußere Kante des Kranzes hinaus, die durch die Drehung des exzentrischen Ringes und die sich daraus ergebende Bewegung der Kugeln verursacht wird, ermöglicht, einen kleineren Kranz- als Spulenkerndurchmesser zu haben und erleichtert den Einsatz und den Auszug erheblich.The expansion of the plastic elements beyond the outer edge of the ring, which is caused by the rotation of the eccentric ring and the resulting movement of the balls, makes it possible to have a smaller ring diameter than the coil core diameter and considerably simplifies use and extraction.

An einer Welle können mehrere Kränze nebeneinander angebracht werden; zwischen die Kränze werden Ringe eingesetzt, um schädliche Reibungen zwischen den Kränzen selbst zu vermeiden.Several wreaths can be attached side by side on a shaft; Rings are inserted between the wreaths to avoid harmful friction between the wreaths themselves.

Als nicht begrenzendes Beispiel wird eine praktische Verwirklichung der Erfindung dargestellt.A practical implementation of the invention is presented as a non-limiting example.

Auf Abb. 1 wird eine Ansicht der Welle gezeigt, auf der die äußere Oberfläche der Welle (A) und eine dar Leisten (B) sichtlich sind; auf Abb. 2 wird ein Querschnitt der Welle (A) mit den Leisten (B) und dem Ausdehnungsschlauch (C) gezeigt; auf Abb. 3 wird ein Querschnitt des Kranzes dargestellt, bei dem der innere exzentrische Ring mit (D) bezeichnet wird, dieser bewirkt durch die Einwirkung der Leisten (B) die Bewegung der Kugeln (E), welche die Elemente (F) anheben, die wiederum auf den Kern der zu wickelnden Spule einwirken, mit (D) bezeichnet wird; Auf Abb. 4 wird eine Ansicht eines Kranzes dergestellt, der an der Welle angebracht ist und neben dem sich ein Reibschutzring (G) befindet.In Fig. 1 a view of the shaft is shown, on which the outer surface of the shaft (A) and one of the strips (B) are visible; Fig. 2 shows a cross section of the shaft (A) with the strips (B) and the expansion hose (C); in Fig. 3 a cross-section of the ring is shown, in which the inner eccentric ring is designated by (D), this causes the movement of the balls (E) by the action of the strips (B), which raise the elements (F), which in turn act on the core of the coil to be wound, denoted by (D); In Fig. 4 a view of a ring is shown, which is attached to the shaft and next to which there is a friction protection ring (G).
