Description

Bremsvorrichtung'-@ür-lmspinnmaschinen Die Erfindung bezieht sich. auf eine am äußeren Umfang von Faden- oder Bandlieferapulen wirkende Bremsvorrichtung für Umspinnmaschinen.Braking device for spin-spinning machines The invention relates to. on a braking device acting on the outer circumference of thread or tape delivery bobbins for spinning machines.

Die neuartige Bremsanordnung ist hier an einer Papierbandumspinnmaschine erläutert. Bisher wurde die Bandlieferspule. im. allgemeinen durch axiales Anpressen auf den Tragbolzen oder in ähnlicher bekannter Art gebremst. Der Nachteil der bisher üblichen Bremsung an Faden- oder Bandlieferspulen besteht darin, daß. die Äbzugspannung des ablaufenden Gutes mit abnehmendem Durchmesser der Lieferspule, im vorliegenden Fall einer Papierbandspule, zunimmt, da die auf die Lieferspule einwirkende Bremskraft stets gleichbleibt.The novel brake arrangement is here on a paper tape spinning machine explained. So far, the tape delivery reel. in the. generally by axial pressing braked on the support bolt or in a similar known manner. The disadvantage of so far usual braking on thread or tape delivery bobbins is that. the withdrawal tension of the goods running off with decreasing diameter of the delivery reel, in the present case Case of a paper tape reel, increases as the braking force applied to the supply reel always remains the same.

Zweck der Erfindung ist, diesen Mangel zu beseitigen und die Bremsvorrichtung so auszubilden, daß die Abzugspannung stets gleichbleibt und die Bremskraft allmählich abnimmt.The purpose of the invention is to remedy this deficiency and the braking device to be trained so that the withdrawal tension always remains the same and the braking force gradually decreases.

Die Erfindung besteht darin, daß das auf die Faden- oder Bandlieferspule wirkende federbelastete Bremsglied verschiebbar in einer konzentrisch zum Drehmittelpunkt angeordneten Führung des die Seele umkreisenden Spulenträgers angeordnet ist.The invention consists in that the thread or tape delivery spool acting spring-loaded braking member displaceable in a concentric to the center of rotation arranged guide of the coil support encircling the core is arranged.

Der Vorteil des Erfindungsgegenstandes gegenüber bekannten Bremsvorrichtungen an Papierbandumspinnmaschinen wird vor allem darin gesehen, daß durch die konzentrische Anordnung der Spulenbremse die nachteilige Wirkung der durch die rasche Drehung des Spulenträg@ers bedingten Fliehkräfte auf die Bremsung aufgehoben werden.The advantage of the subject matter of the invention over known braking devices on paper tape spinning machines is seen above all in the fact that the concentric Arrangement of the reel brake the adverse effect of the rapid rotation the centrifugal forces on the braking caused by the coil carrier.

In der Zeichnung ist die Erfindung dargestellt: Der-Spulenträger 7 weist eine konzentrische Aussparung 3 auf, deren Mittellinie ein Kreis ist, der genau oder annähernd durch die Mittelpunkte der auf Tragbolzen 6 gelagerten Papierbandlieferspulen 5 geht. In dieser Aussparung 3 sitzen verschiebbare Bremsglieder z, die unter dem Einfluß von ebenfalls in der ringförmigen Aussparung 3 untergebrachten Schraubenfedern i an den Bandlieferspulen 5 anliegen. Mit abnehmendem Durchmesser der Papierbandlieferspule 5 nimmt auch die Bremskraft der sich mehr und mehr drehenden Schraubenfeder i ab, so daß die Abzugspannung des auf das Seelenkabel q. aufzuwickelnden Papierbandes 8 gleichbleibt.The invention is shown in the drawing: The coil carrier 7 has a concentric recess 3, the center line of which is a circle, the exactly or approximately through the centers of the paper tape delivery reels mounted on support bolts 6 5 goes. In this recess 3 sliding brake members sit z, which under the Influence of helical springs also housed in the annular recess 3 i rest on the tape delivery reels 5. With decreasing diameter of the paper tape supply reel 5 the braking force of the more and more rotating coil spring i also decreases, so that the withdrawal tension of the core cable q. to be wound up 8 remains the same.
