Abstract

The arrangement has a sleeve-shaped carrier (5) rotatable about an axis (2) with a characteristic maximum speed and an application tube (1) rotating about the carrier with a wire outlet connected to the carrier via a holding arrangement. A compensation plate (6) used to compensate for the imbalance caused by the application tube and holding arrangement is mounted opposite the application tube relative to the rotation axis in each axial position and can rotate about the carrier. The plate thickness and height are selected to locally compensate for the imbalance caused by the application tube and mounting plate in each plane perpendicular to the rotation axis.

Description

Die vorliegende Erfindung betrifft einen Windungsleger für Draht, mit einem maximal mit einer Nenndrehzahl um eine Drehachse rotierbaren hülsenförmigen Träger und einem um den Träger umlaufenden Legerohr mit einem Drahtauslaß, das mit dem Träger über eine Haltevorrichtung verbunden ist.The present invention relates to a winding layer for wire, with a maximum that can be rotated around an axis of rotation at a nominal speed sleeve-shaped carrier and a circumferential around the carrier Laying pipe with a wire outlet that connects to the carrier via a holding device connected is.

Derartige Windungsleger sind bekannt.Winding layers of this type are known.

Das Legerohr und das Halteblech bewirken eine Unwucht. Diese Unwucht muß ausgeglichen werden. Im Stand der Technik ist hierzu bspw. bekannt, am Träger einen Ausgleichsklotz und/oder mehrere jeweils in einer Axialebene verlaufende Blechrippen vorzusehen. Hierdurch wird die unwucht aber nicht vollständig ausgeglichen. Bei hohen Drehzahlen tritt somit eine elastische Deformierung der Haltebleche auf. Darüber hinaus erwärmt der zu legende Draht auch das Halteblech, wodurch eine zusätzliche Verformung auftritt. Ein derartiger Windungsleger neigt bei hohen Drehzahlen zu Schwingungen.The laying tube and the holding plate cause an imbalance. This unbalance must be balanced. For example, in the prior art. known, a compensation block and / or several each on the carrier to provide sheet metal ribs running in an axial plane. Hereby the unbalance is not completely compensated. At high Speeds, there is thus an elastic deformation of the holding plates on. In addition, the wire to be laid also heats the holding plate, causing additional deformation. Such one Coil layer tends to vibrate at high speeds.

Um den Windungsleger schwingungsfest zu machen, sieht eine andere Lösung des Standes der Technik vor, ein Ausgleichsrundeisen über ein weiteres Halteblech derart um den Träger umlaufen zu lassen, daß sich alle Ausgleichsgewichte genau gegenüber dem jeweiligen Gewicht aus Legerohr und Halteblech befinden. Bei diesem Windungsleger sind jedoch mehrere Schweißnähte schlecht zugänglich. Dadurch entsteht nur eine unsichere Verbindung zwischen dem Träger und den Halteblechen sowie etwaigen Versteifungsblechen. Another person sees to make the winding layer vibration-proof Solution of the state of the art before, a compensation round bar another holding plate in order to circulate the carrier, that all balance weights are exactly opposite each other Weight from the laying tube and holding plate. With this coil layer however, several welds are difficult to access. Thereby there is only an insecure connection between the wearer and the Retaining plates and any stiffening plates.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Windungsleger für Draht zu schaffen, bei dem auf möglichst einfache Weise sowohl statische als auch dynamisch auftretende Unwuchten eliminiert sind und darüber hinaus alle Schweißnähte leicht zugänglich sind.The object of the present invention is a winding layer to create wire that is as simple as possible Both static and dynamic imbalances occur are eliminated and, in addition, all weld seams are easily accessible are.

Die Aufgabe wird dadurch gelöst, daß zum Ausgleich der durch das Legerohr und die Haltevorrichtung verursachten Unwucht am Träger ein Ausgleichsblech mit einer Blechdicke, einer Blechhöhe und einer Eigenfrequenz angeordnet ist, daß das Ausgleichsblech dem Legerohr bezüglich der Drehachse an jeder Axialposition gegenüberliegt und in dem Teilabschnitt ebenfalls um den Träger umläuft und daß die Blechdicke und die Blechhöhe derart gewählt sind, daß die durch das Legerohr und das Halteblech verursachte Unwucht in jeder zur Drehachse senkrechten Ebene lokal ausgeglichen ist.The object is achieved in that to compensate for the The laying tube and the holding device caused imbalance on the carrier a shim with a sheet thickness, a sheet height and one Natural frequency is arranged that the compensating plate the laying pipe with respect to the axis of rotation at each axial position and in the section also revolves around the carrier and that the Sheet thickness and the sheet height are chosen such that the Laying pipe and the holding plate caused unbalance in each to the axis of rotation vertical plane is locally balanced.

Wenn die Blechdicke und die Blechhöhe derart gewählt sind, daß die Eigenfrequenz des Ausgleichsblechs oberhalb der Nenndrehzahl liegt, ist ein Flattern des Ausgleichsblechs ausgeschlossen. Versteifungen für das Ausgleichsblech sind nicht erforderlich.If the sheet thickness and the sheet height are chosen such that the Natural frequency of the compensating plate is above the nominal speed, flutter of the compensating plate is excluded. Stiffeners are not required for the shim.

Wenn am Halteblech zumindest im Bereich des Auslaßendes zwei axial verlaufende Versteifungsbleche angeordnet sind, die in einer Axialebene liegen und das Halteblech nach beiden Seiten abstützen, treten in den Schweißnähten der Versteifungsbleche lediglich niedrige Zugspannungen auf. Das gleichzeitige Auftreten von Zug- und Biegespannungen wird vermieden.If two axially on the holding plate at least in the region of the outlet end extending stiffening plates are arranged in an axial plane lie and support the retaining plate on both sides, step only low welds in the stiffening plate welds Tensile stresses on. The simultaneous occurrence of tensile and bending stresses is avoided.

Further advantages and details emerge from the following description of an exemplary embodiment. Show in principle
Figure 1
a coil layer in axial section and
Figure 2
the winding layer of Figure 1 from the front.

Gemäß den Figuren weist ein Windungsleger für Draht einen hülsenförmigen Träger 5 auf. Der Träger 5 ist im Betrieb maximal mit einer Nenndrehzahl n um eine Drehachse 2 rotierbar. Um den Träger 5 läuft ein Legerohr 1 um. Das Legerohr 1 ist mit dem Träger 5 über ein Halteblech 7 verbunden und weist einen Drahtauslaß 3 auf, von dem im Betrieb der Draht in Windungen abgegeben wird. Die Verbindung des Legerohrs 1 mit dem Halteblech 7 erfolgt dabei über sogenannte Augen 8.According to the figures, a winding layer for wire has a sleeve-shaped Carrier 5 on. The carrier 5 is in operation with a maximum of one Nominal speed n rotatable about an axis of rotation 2. Around the carrier 5 runs a laying tube 1 um. The laying tube 1 is connected to the carrier 5 Holding plate 7 connected and has a wire outlet 3, of which the wire is delivered in turns during operation. The connection the laying tube 1 with the holding plate 7 takes place via so-called Eyes 8.

Das Halteblech 7, die Augen 8 und das Legerohr 1 bewirken eine Unwucht. Zum Ausgleich dieser Unwucht ist ein dickes Ausgleichsblech 6 mit einer Blechdicke d und einer Blechhöhe h am Träger 5 angeordnet. Das Ausgleichsblech 6 läuft ebenfalls um den Träger 5 um und liegt dem Legerohr 1 bezüglich der Drehachse an jeder Axialposition gegenüber. Die Blechdicke d und die Blechhöhe h sind derart gewählt, daß die durch das Legerohr 1, das Halteblech 7 und die Augen 8 verursachte Unwucht in jeder zur Drehachse 2 senkrechten Ebene lokal ausgeglichen ist.The holding plate 7, the eyes 8 and the laying tube 1 cause one Unbalance. To compensate for this imbalance is a thick shim 6 with a sheet thickness d and a sheet height h on the carrier 5. The compensating plate 6 also runs around the carrier 5 and is the laying tube 1 with respect to the axis of rotation at any axial position across from. The sheet thickness d and the sheet height h are selected in such a way that through the laying tube 1, the holding plate 7 and the eyes 8th caused unbalance locally in each plane perpendicular to the axis of rotation 2 is balanced.

Aufgrund seines Materials (Stahl), der Blechdicke d und der Blechhöhe h weist das Ausgleichsblech 6 eine Eigenfrequenz f auf. Die Blechdicke d und die Blechhöhe h sind aber derart gewählt, daß die Eigenfrequenz f des Ausgleichsblechs 6 oberhalb der Nenndrehzahl n liegt. Versteifungselemente für das Ausgleichsblech 6 sind daher entbehrlich.Because of its material (steel), the sheet thickness d and the sheet height h, the compensating plate 6 has a natural frequency f. The Sheet thickness d and the sheet height h are chosen such that the Natural frequency f of the compensating plate 6 above the nominal speed n lies. Stiffening elements for the compensating plate 6 are therefore dispensable.

Zumindest im Bereich des Drahtauslasses 3 sind am Halteblech 7 zwei axial verlaufende Versteifungsbleche 9 angeordnet. Die Versteifungsbleche 9 liegen in einer Axialebene und stützen das Halteblech 7 nach beiden Seiten ab. Hierdurch treten in den Schweißnähten lediglich geringe Zugspannungen, aber keine gemischten Zug- und Biegespannungen mehr auf. At least in the area of the wire outlet 3 there are two on the holding plate 7 axially extending stiffening plates 9 are arranged. The stiffening sheets 9 lie in an axial plane and support the holding plate 7 on both sides. This only occurs in the welds low tensile stresses, but no mixed tensile and Bending stresses more.
