Description

Die vorliegende Erfindung betrifft eine Spindelanordnung für eine Spinn- oder Zwirnmaschine, insbesondere eine Ringspinnmaschine, mit einer Vielzahl von nebeneinander angeordneten, über einen Tangentialriemen angetriebenen Spindeln.
Die Spindelanordnung umfasst eine Spindelbank mit Bohrungen zur Befestigung der Spindeln, eine erste Spindel, eine neben der ersten Spindel angeordnete, zweite Spindel, eine federnd gelagerte erste Anpressrolle, die zwischen der ersten Spindel und der zweiten Spindel angeordnet ist und den Tangentialriemen gegen die Wirtel der ersten Spindel und der zweiten Spindel drückt, und eine neben der zweiten Spindel angeordnete dritte Spindel. Die Mittelpunkte der Bohrungen der ersten Spindel und der zweiten Spindel liegen auf einer Spindelgeraden. Die Erfindung betrifft ferner eine Ringspinnmaschine mit der Spindelanordnung.The present invention relates to a spindle arrangement for a spinning or twisting machine, in particular a ring spinning machine, with a plurality of juxtaposed, driven via a tangential spindles.
The spindle assembly comprises a spindle bank with bores for fastening the spindles, a first spindle, a second spindle arranged next to the first spindle, a spring-mounted first pressure roller, which is arranged between the first spindle and the second spindle and the tangential belt against the whorl of first spindle and the second spindle, and a third spindle disposed adjacent to the second spindle. The centers of the bores of the first spindle and the second spindle lie on a spindle straight line. The invention further relates to a ring spinning machine with the spindle assembly.

Die DE 31 06 307 A1 offenbart eine Spindelanordnung für eine Spinn- oder Zwirnmaschine mit Spindeln, die mittels eines Tangentialriemens angetrieben werden. Der Tangentialriemen berührt die Wirtel der Spindeln, wie der Name schon sagt, tangential. Durch die nur tangentiale Berührung können die Reibung und damit die Verluste gering gehalten werden.The DE 31 06 307 A1 discloses a spindle assembly for a spinning or twisting machine with spindles driven by a tangential belt. The tangential belt touches the whorls of the spindles, as the name implies, tangentially. Due to the only tangential contact the friction and thus the losses can be kept low.

Die Spindeln sind auf einer Spindelbank angeordnet. Die Spindelbank weist Bohrungen zur Befestigung der Spindeln auf. Dazu wird das Spindellager in die Bohrungen eingelassen. Um eine sichere Mitnahme der Spindeln durch den Tangentialriemen zu gewährleisten, sind die Bohrungen der Spindeln präzise so gefertigt, dass alle Bohrungen auf einer Geraden liegen. Präziser ausgedrückt liegen die Mittelpunkte der Bohrungen auf einer Geraden. Eine Gerade durch die Mittelpunkte der Bohrungen der Spindeln wird im Folgenden als Spindelgerade bezeichnet. Je zwei Spindeln ist eine federnd gelagerte Anpressrolle zugeordnet, um den Tangentialriemen gegen die Wirtel der Spindeln zu drücken. Durch den Anpressdruck ergibt sich eine sehr kleine Umschlingung an den Wirteln der Spindeln, die ausreicht, um die Spindeln sicher anzutreiben. Der bekannte Tangentialriemenantrieb für Spindeln einer Spinn- oder Zwirnmaschine erfordert einen hohen konstruktiven Aufwand. Insbesondere ist für zwei Spindeln immer eine Anpressrolle erforderlich.The spindles are arranged on a spindle bank. The spindle bank has holes for fastening the spindles. For this purpose, the spindle bearing is inserted into the holes. To ensure safe entrainment of the spindles through the tangential belt, the bores of the spindles are precisely machined so that all bores lie on a straight line. More precisely, the centers of the holes lie on a straight line. A straight line through the centers of the bores of the spindles is referred to below as the spindle straight line. Each two spindles is assigned a spring-mounted pressure roller to press the tangential belt against the whorl of the spindles. The contact pressure results in a very small wrap around the whorls of the spindles, which is sufficient to safely drive the spindles. The well-known Tangentialriemenantrieb for spindles of a spinning or twisting machine requires a high design effort. In particular, a pressure roller is always required for two spindles.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine vereinfachte Spindelanordnung für Spinn- oder Zwirnmaschinen zu schaffen.It is therefore the object of the present invention to provide a simplified spindle arrangement for spinning or twisting machines.

Zur Lösung der Aufgabe ist der Mittelpunkt der Bohrung der dritten Spindel beabstandet zu der Spindelgeraden angeordnet, wobei sich der Mittelpunkt der Bohrung der dritten Spindel und die erste Anpressrolle auf der gleichen Seite der Spindelgeraden befinden.To solve the problem, the center of the bore of the third spindle is spaced from the spindle line, wherein the center of the bore of the third spindle and the first pressure roller are on the same side of the spindle line.

Durch die erfindungsgemäße Spindelanordnung ist für jeweils drei Spindeln nur eine Anpressrolle erforderlich. Die Anzahl der benötigten Anpressrollen kann also um ein Drittel reduziert werden. Der Versatz der Bohrung ist mittels moderner Fertigungsmethoden ohne zusätzlichen Aufwand möglich.The spindle arrangement according to the invention requires only one pressure roller for every three spindles. The number of required pressure rollers can therefore be reduced by one third. The offset of the hole is possible by means of modern production methods without additional effort.

Vorzugsweise ist der Abstand des Mittelpunktes der Bohrung der dritten Spindel von der Spindelgeraden größer als 0,5mm. Bereits ein Abstand von 0,5 mm stellt eine zuverlässige Mitnahme der dritten Spindel durch den Tangentialriemen sicher.Preferably, the distance of the center of the bore of the third spindle of the spindle line is greater than 0.5mm. Even a distance of 0.5 mm ensures reliable entrainment of the third spindle by the tangential belt.

Gemäß einer Weiterbildung der Erfindung ist der Abstand des Mittelpunktes der Bohrung der dritten Spindel von der Spindelgeraden kleiner als 2 mm. Durch eine Obergrenze des Abstandes wird sichergestellt, dass der Versatz der Spindeln keinen negativen Einfluss auf den Spinn- oder Zwirnprozess hat.According to one embodiment of the invention, the distance of the center of the bore of the third spindle of the spindle line is less than 2 mm. An upper limit of the distance ensures that the offset of the spindles has no negative influence on the spinning or twisting process.

Gemäß einer besonders bevorzugten Ausführungsform ist eine vierte Spindel neben der dritten Spindel angeordnet und der Mittelpunkt der Bohrung der vierten Spindel ist entsprechend der dritten Spindel beabstandet zu der Spindelgeraden. Bei dieser Anordnung ist für jeweils vier Spindeln nur eine Anpressrolle erforderlich. Diese Ausführungsform der vorliegenden Erfindung ermöglicht im Vergleich zum Stand der Technik also die Hälfte der Anpressrollen einzusparen.According to a particularly preferred embodiment, a fourth spindle is arranged next to the third spindle and the center of the bore of the fourth spindle is spaced apart from the spindle straight line corresponding to the third spindle. In this arrangement, only one pressure roller is required for every four spindles. This embodiment of the present invention thus allows saving in comparison to the prior art, half of the pressure rollers.

Vorzugsweise sind eine fünfte Spindel und eine sechste Spindel neben der vierten Spindel angeordnet und die Mittelpunkte der Bohrungen der fünften Spindel und der sechsten Spindel liegen auf der Spindelgeraden. Zwischen der fünften Spindel und der sechsten Spindel kann eine federnd gelagerte zweite Anpressrolle angeordnet sein, die den Tangentialriemen gegen die Wirtel der fünften Spindel und der sechsten Spindel drückt.Preferably, a fifth spindle and a sixth spindle are arranged adjacent to the fourth spindle, and the centers of the bores of the fifth spindle and the sixth spindle lie on the spindle straight line. Between the fifth spindle and the sixth spindle, a spring-mounted second pressure roller may be arranged, which is the tangential belt against the whorl of the fifth spindle and the sixth spindle suppressed.

Werden die vierte, fünfte und sechste Spindel in der beschriebenen Weise angeordnet, ergibt sich eine spiegelsymmetrische Anordnung zu der ersten, zweiten und dritten Spindel.If the fourth, fifth and sixth spindle arranged in the manner described, results in a mirror-symmetrical arrangement to the first, second and third spindle.

Die erste Anpressrolle und die zweite Anpressrolle können vorzugsweise zwischen der dritten Spindel und der vierten Spindel an der Spindelbank befestigt sein. Eine gemeinsame Befestigung der ersteh und zweiten Anpressrolle an einem Befestigungspunkt an der Spindelbank zwischen der dritten Spindel und der vierten Spindel unterstützt die einfache Konstruktion der erfindungsgemäßen Spindelanordnung.The first pressure roller and the second pressure roller may preferably be fastened between the third spindle and the fourth spindle on the spindle bench. A common attachment of the first and second pressure roller at an attachment point on the spindle bank between the third spindle and the fourth spindle supports the simple construction of the spindle arrangement according to the invention.

Die vorliegende Erfindung betrifft außerdem eine Ringspinnmaschine mit einer erfindungsgemäßen Spindelanordnung.The present invention also relates to a ring spinning machine with a spindle arrangement according to the invention.

Die Ringspinnmaschine weist neben der Spindelbank auch eine Ringbank mit Bohrungen zur Befestigung von Spinnringen auf. Dabei ist der ersten Spindel ein erster Spinnring, der zweiten Spindel ein zweiter Spinnring und der dritten Spindel ein dritter Spinnring zugeordnet. Vorzugsweise liegen die Mittelpunkte der Bohrungen des ersten Spinnringes und des zweiten Spinnringes auf einer Spinnringgeraden und der Mittelpunkt der Bohrung des dritten Spinnringes ist beabstandet zu der Spinnringgeraden, wobei der Abstand des Mittelpunktes der Bohrung des dritten Spinnringes von der Spinnringgeraden mit dem Abstand des Mittelpunktes der Bohrung der dritten Spindel von der Spindelgeraden korrespondiert.The ring spinning machine has in addition to the spindle bank and a ring rail with holes for attachment of spinning rings. Here, the first spindle is a first spinning ring, the second spindle a second spinning ring and the third spindle associated with a third spinning ring. Preferably, the centers of the bores of the first spinning ring and the second spinning ring lie on a spinning ring line and the center of the bore of the third spinning ring is spaced from the spinning ring line, wherein the distance of the center of the bore of the third spinning ring from the spinning ring line with the distance of the center of the bore the third spindle corresponds to the spindle straight line.

Durch die beschriebene Anpassung der Ringbank kann auf einfache Weise eine Zentrierung der Spinnringe und der Spindeln erfolgen. Bei einem Versatz weiterer Spindeln beziehungsweise der entsprechenden Bohrungen in der Spindelbank können die Bohrungen der Spinnringe in der Ringbank analog angepasst werden.By the described adaptation of the ring rail can be done in a simple manner centering of the spinning rings and the spindles. With an offset of other spindles or the corresponding holes in the spindle bank, the holes of the spinning rings in the ring rail can be adjusted analogously.

Insbesondere wenn eine vierte Spindel, wie oben beschrieben, ausgebildet ist, und der vierten Spindel ein vierter Spinnring zugeordnet ist, kann der Mittelpunkt der Bohrung des vierten Spinnringes in der Ringbank entsprechend des Mittelpunktes der Bohrung des dritten Spinnringes von der Spinnringeraden beabstandet sein. Der fünften und sechsten Spindel kann ein fünfter und sechster Spinnring zugeordnet sein. Die Mittelpunkte der Bohrungen des fünften und sechsten Spinnringes in der Ringbank können dann wieder auf der Spinnringgeraden liegen.In particular, when a fourth spindle is formed as described above and the fourth spindle is associated with a fourth spinning ring, the center of the bore of the fourth spinning ring in the ring rail may be spaced from the spinning ring line corresponding to the center of the bore of the third spinning ring. The fifth and sixth spindle may be associated with a fifth and sixth spinning ring. The centers of the holes of the fifth and sixth spinning ring in the ring rail can then lie again on the spinning ring line.

Ansonsten kann die erfindungsgemäße Spindelanordnung, ohne dass weitere Anpassungen erforderlich sind, in Verbindung mit bekannten Ringspinnmaschinen genutzt werden. Fadenleitelemente der Ringspinnmaschine, wie Fadenführer und Balloneinengungsring, werden ohnehin zur Achse der Spindel zentriert.Otherwise, the spindle assembly according to the invention, without further adjustments are required to be used in conjunction with known ring spinning machines. Thread guiding elements of the ring spinning machine, such as yarn guide and balloon constriction ring, are anyway centered to the axis of the spindle.

Bei einer erfindungsgemäßen Spindelanordnung reicht ein verhältnismäßig kleiner Versatz der Spindeln aus. Aus diesem Grunde können auch bekannte Doffeinrichtungen in Verbindung mit der erfindungsgemäßen Spindeleinrichtung verwendet werden. Der Versatz der Spindeln kann deutlich kleiner gewählt werden als der Fangbereich der Greifer der Doffeinrichtung.In a spindle arrangement according to the invention, a relatively small offset of the spindles is sufficient. For this reason, known Doffeinrichtungen can be used in conjunction with the spindle device according to the invention. The offset of the spindles can be chosen significantly smaller than the capture range of the gripper doffeinrichtung.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawings.
