Abstract

The support for the guide members which press the drive belt against the spindle whorls, is mounted in the machine independently of the mountings for the spindle assemblies, the support pref. being a beam. The separate support beam provides a standard unit usable in different machines e.g. with vertical or horizontal spindles, and vibrations are not transmitted to the spindle mountings from the beam.

Description

"DOPPELDRAHTZWIRNMASCHINE""DOUBLE WIRE TWISTING MACHINE"

Doppeldraktzwirnmaschinen besitzen vorzugsweise eine Vielzahl von Spindeln, die in zwei Reihen angeordnet sind, und durch einen endlosen, sich über die gesamte Maschinenlänge erstreckenden Tangentialriemen angetrieben werden. Da die Riemen tangential an den Wirteln der Spindeln anliegen, müssen sie erhebliche Radialkräfte auf die Wirtel ausüben. Hierzu müssen sie sehr stramm gespannt sein. Infolge der Elastizität der Riemen wird zur Spannung ein großer Spannweg benötigt.Double-twist twisting machines preferably have a plurality of Spindles, which are arranged in two rows, and by an endless one, are about the entire length of the machine extending tangential belts are driven. There If the belts are tangential to the whorls of the spindles, they must be considerable Apply radial forces to the whorls. To do this, they must be stretched very tightly. As a result of the elasticity of the belt, a large tension path is required for tensioning.

Dieser Spannweg bedingt bei herkömmlichen Konstruktionen eine entsprechende Verlängerung der Maschine.This tension path requires a corresponding one in conventional designs Extension of the machine.

Aufgabe der Erfindung ist es, den erforderlichen Spannweg für den Tangentialriemen einer Doppeldrahtzwirnmaschine bereitzustellen, ohne daß hierdurch die Maschinenlänge in nennenswerter Weise vergrößert werden muß.The object of the invention is to provide the necessary tension for the Provide tangential belt of a two-for-one twisting machine without this the machine length must be increased significantly.

Die Lösung besteht aus den folgenden Merkmalen: Der Tangentialriemen umschlingt an dem Spannende seines Laufs eine ungefähr in der senkrechten Maschinenmittelebene angeordnete Rolle sattelförmig. Beidseits dieser Rolle sind auf einem in Spannrichtung beweglichen Schlitten zwei drehbare Rollen mit zur Riemenlaufebene (Umlaufebene) senkrechter Achse angeordnet, die der Tangentialriemen umschlingt. Diese beiden Rollen haben relativ zueinander einen festen Abstand. Der relative Abstand der einen Rolle zu den beiden anderen ist jedoch parallel zur Maschinenlängsachse veränderbar. Die Rolle, der der Tangentialriemen sattelförmig aufliegt, ist vorzugsweise auf der Achse eines stehenden Antriebsmotors befestigt.The solution consists of the following features: The tangential belt at the tensioning end of its barrel wraps around a roughly in the vertical machine center plane arranged roll saddle-shaped. Both sides of this roll are on one in the tensioning direction movable carriage two rotatable rollers with to the belt running plane (circumferential plane) arranged vertical axis around which the tangential belt loops. These two Rollers have a fixed spacing relative to one another. The relative distance of the one However, role in relation to the other two can be changed parallel to the longitudinal axis of the machine. The role on which the tangential belt rests in the shape of a saddle is preferably on attached to the axis of a stationary drive motor.

Die beiden Rollen, die einen festen Abstand zueinander haben, sind vorzugsweise auf einem Schlitten angeordnet, der in Maschinenlangsrichtung beweglich ist. In dieser Ausführung ist die andere Rolle ortsfest gelagert.The two roles that are a fixed distance from each other are preferably arranged on a carriage which is movable in the longitudinal direction of the machine is. In this version, the other role is mounted in a stationary manner.

Bei dieser Konstruktion ist der Spannweg des Schlittens lediglich halb so groß wie die durch die Spannung bewirkte Verlängerung des Riemens.In this construction, the slide's clamping path is only half the tension elongation of the belt.

Das in den Figuren 1 und 2 gezeigte Ausführungsbeispiel stellt einen Horizontalschnitt durch ei-ne Doppeldrahtzwirnmaschine dar. Der endlos umlaufende Tangentialriemen 1 liegt an den Wirteln 2 der Doppeldrahtzwirnspindeln tangential an und übt infolge der Andrückrollen 3 eine radiale Anpreßkraft auf die Wirtel aus und setzt diese dadurch in Drehung. Der Tangentialriemen 1 umschlingt an einem Maschinenende die frei drehbare Rolle 4. Am anderen Maschinenende, dem sogenannten "Spannende" liegt er der ortsfesten Rolle 5 sattelförmig auf und zwar im wesentlichen mit einem Umschlingungswinkel von 180°.The embodiment shown in Figures 1 and 2 represents a Horizontal section through a two-for-one twisting machine. The endless one Tangential belt 1 lies tangentially on whorls 2 of the two-for-one twisting spindles and exerts a radial pressing force on the whorl as a result of the pressure rollers 3 and thereby sets it in rotation. The tangential belt 1 loops around one end of the machine the freely rotatable roller 4. At the other end of the machine, the so-called "tensioning" it lies on the stationary roller 5 in the shape of a saddle, essentially with a Wrap angle of 180 °.

Gleichzeitig umschlingt der Tangentialriemen im Bereich des Spannendes die frei drehbaren Rollen6 und 7. Diese sind auf einem parallel zur Aufspannebene des Tangentialriemens beweglichen Schlitten 8 frei drehbar gelagert.At the same time, the tangential belt wraps around in the area of the tension the freely rotating rollers 6 and 7. These are on a parallel to the clamping plane of the tangential belt movable carriage 8 freely rotatably mounted.

Die Bewegung des Schlittens 8 geschieht durch eine Schraubspindel 9. Die Rolle 5 sitzt - wie Fig. 2 insbesondere zeigt - auf der Achse 9 des Antr-iebsmotors 10. Der Schlitten 8 ist durch Winkeleisen 11, 12in den im Maschinengestell befestigten Schienen 13, 14 geführt.The carriage 8 is moved by a screw spindle 9. The roller 5 sits - as FIG. 2 shows in particular - on the axis 9 of the drive motor 10. The carriage 8 is fastened in the machine frame by means of angle irons 11, 12 Rails 13, 14 out.
