Abstract

The invention is applicable to bobbin winding machines with roller drive of the bobbin. Drive mechanisms of this type have separate motors for the driven roller and the cross windings, with coupling and bearing points for these working elements. To minimize the required space while saving on structural parts, the motors are housed in a common drive housing, which moreover is designed so that the working elements can be attached thereto. The housing is also equipped with means for its own displacement for increased bobbin diameter.

Description

Die Erfindung betrifft eine Antriebseinrichtung für einen Spulkopf an Spulmaschinen mit Treibwalzenantrieb der Spule.The invention relates to a drive device for a winding head on winding machines with drive roller drive of the coil.

Bekannte Spulköpfe, bei denen der Antrieb der Spule mittels Friktion erfolgt, besitzen je einen Antriebsmotor für Treibwalze und Changierung. Dabei sind häufig zwischen dem Motor und der Welle dieser Arbeitsorgane Kupplungen oder Riementriebe angeordnet. Nachteilig ist, daß die Lagerstellen für die Motoren und die Arbeitsorgane sowie die Kuppelstellen einen relativ großen Bauraum benötigen und außerdem einem gewissen Verschleiß unterliegen. Außerdem ist es erforderlich, eine Relativbewegung zwischen Treibwalze mit Changierung gegenüber der Spule zu realisieren, um dem wachsenden Spulendurchmesser Rechnung zu tragen.Known coil heads, in which the drive of the coil by means of friction done, each have a drive motor for the drive roller and Traversing. There are often between the motor and the shaft these work organs arranged clutches or belt drives. The disadvantage is that the bearings for the motors and Work organs and the coupling points have a relatively large installation space need and also subject to some wear. It is also necessary to have a relative movement between the drive roller with traversing in relation to the coil to realize the to take increasing coil diameter into account.

Aus der DE-A 2 060 954 ist eine Antriebseinrichtung bekannt, bei welcher die Treibwalze mit dem sie antreibenden Motor und die Changierung mit dem sie antreibenden Motor an einem Träger befestigt sind. Der Träger ist an einem Ende an einer Achse schwenkbar gelagert, so daß die Treibwalze mit Motor und die Changiereinrichtung mit Motor sich auf einer kreisförmigen Bahn von der zu wickelnden Spule wegbewegen können.A drive device is known from DE-A 2 060 954, in which the drive roller with the motor driving it and the oscillation with the motor driving it on a carrier are attached. The beam is at one end on an axis pivoted so that the drive roller with motor and the Traversing device with a motor on a circular Can move web away from the spool to be wound.

Diese bekannte Antriebseinrichtung besitzt den Nachteil, daß sie seitlich zur Spule hin ausgelenkt wird. Zum einen wird aufgrund der ständigen Veränderung der Relativlage zwischen Treibwalze und Spule eine Nachstellung der Anlagekraft erforderlich und zum anderen bedarf die Antriebseinrichtung eines erhöhten Platzbedarfs im Spulkopf. Zudem erfordert die Antriebseinrichtung einen erheblichen Befestigungsaufwand, da die Motoren und die Arbeitsorgane einzeln an dem Träger befestigt sind. Hierbei können die zwischen den Motoren und dem Arbeitsorgan entstehenden Fluchtungsfehler nur mittels Kupplungen überbrückt werden.This known drive device has the disadvantage that it is laterally deflected towards the coil. For one thing due to the constant change in the relative position between Driving roller and spool require readjustment of the contact force and on the other hand the drive device needs one increased space requirement in the winding head. In addition, the drive device requires a considerable amount of attachment, because the motors and the working elements are individually attached to the carrier are. Here, the between the motors and the Alignment errors resulting from the working element can only be achieved using couplings be bridged.

Die Aufgabe der Erfindung ist es, den Platzbedarf für die Antriebseinrichtungen und die Einrichtungen für die Relativbewegung von Arbeitsorganen und Spule (n) zu minimieren und dabei Bauelemente einzusparen.The object of the invention is the space required for the drive devices and the devices for the relative movement of Minimize work organs and coil (s) while keeping components save.

Gelöst wird die Aufgabe durch den kennzeichnenden Teil des Anspruches 1. Danach sind die Motoren für die Treibwalze und die Changierung in einem gemeinsamen Antriebsgehäuse untergebracht, welches Kühlrippen für die Motoren aufweist und so ausgebildet ist, daß die Arbeitsorgane daran befestigt werden können. Weiterhin sind an diesem Antriebsgehäuse Mittel für seine eigene Verschiebung bei wachsendem Spulendurchmesser vorgesehen.The task is solved by the characterizing part of the claim 1. Then are the motors for the drive roller and the traversing housed in a common drive housing, which Has cooling fins for the motors and is designed so that the Work organs can be attached to it. Furthermore are on this drive housing means for its own displacement increasing coil diameter provided.
