Description

Spindelanordnung und Ringspinnmaschine mit der Spindelanordnung 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.Spindle arrangement and ring spinning machine with the spindle arrangement The present invention relates to a spindle arrangement for a spinning or twisting machine, in particular a ring spinning machine, with a multiplicity of spindles arranged next to one another and driven via a tangential belt.

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 spindle arrangement 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 whorls of the first spindle and the second spindle pushes, and a third spindle arranged next to the second spindle. The centers of the holes of the first spindle and the second spindle lie on a straight spindle line. The invention also relates to a ring spinning machine with the spindle arrangement.

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 arrangement for a spinning or twisting machine with spindles which are driven by means of a tangential belt. The tangential belt touches the whorls of the spindles, as the name suggests, tangentially. The only tangential contact means that friction and thus losses can be kept low.

JP H07 157928 A und CN 202 936 539 U offenbaren eine Spindelanordnung für eine Spinn- oder Zwirnmaschine, insbesondere eine Ringspinnmaschine, mit einer Vielzahl von nebeneinander angeordneten, über einen Tangentialriemen angetriebenen Spindeln umfassend 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, wobei die Mittelpunkte der Bohrungen der ersten Spindel und der zweiten Spindel auf einer Spindelgeraden liegen, wobei der Mittelpunkt der Bohrung der dritten Spindel beabstandet zu der Spindelgeraden ist und wobei sich der Mittelpunkt der Bohrung der dritten Spindel und die erste Anpressrolle auf der gleichen Seite der Spindelgeraden befinden. JP H07 157928 A and CN 202 936 539 U disclose a spindle arrangement for a spinning or twisting machine, in particular a ring spinning machine, with a plurality of spindles arranged next to one another and driven via a tangential belt, comprising 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 presses the tangential belt against the whorls of the first spindle and the second spindle, and a third spindle arranged next to the second spindle, the centers of the bores of the first spindle and the second spindle lie on a straight spindle line, the center of the bore of the third spindle being spaced apart from the straight spindle and the center of the bore of the third spindle and the first pressure roller being on the same side of the straight spindle.

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.The spindles are arranged on a spindle bench. The spindle bench has holes for fastening the spindles. To do this, the spindle bearing is let into the bores. In order to ensure that the spindles are safely carried by the tangential belt, the holes in the spindles are precisely manufactured so that all holes lie on a straight line. To put it more precisely, the centers of the holes lie on a straight line. A straight line through the center points of the bores of the spindles is referred to below as a spindle straight line. One is springy for every two spindles assigned pressure roller to press the tangential belt against the whorls of the spindles. The contact pressure creates a very small wrap around the whorls of the spindles, which is sufficient to safely drive the spindles.

Der bekannte Tangentialriemenantrieb für Spindeln einer Spinn- oder Zwirnmaschine erfordert einen hohen konstruktiven Aufwand. Insbesondere ist für zwei Spindeln immer eine Anpressrolle erforderlich.The well-known tangential belt drive for spindles of a spinning or twisting machine requires a high level of structural 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.

Die Aufgabe wird durch der Spindelanordnung gemäß Anspruch 1 gelöst. 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. Erfindungsgemäss 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.The object is achieved by the spindle arrangement according to claim 1. Due to the spindle arrangement according to the invention, only one pressure roller is required for every three spindles. The number of pressure rollers required can therefore be reduced by a third. The offset of the bore is possible without additional effort using modern production methods. According to the invention, the distance between the center point of the bore of the third spindle and the straight spindle line is greater than 0.5 mm. A distance of just 0.5 mm ensures that the third spindle is reliably carried by the tangential belt.

Erfingungsgemäss 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 the invention, the distance between the center point of the bore of the third spindle and the straight spindle line is less than 2 mm. An upper limit on the distance ensures that the offset of the spindles does not have a negative impact 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 point of the bore of the fourth spindle is at a distance from the straight spindle line corresponding to the third spindle. With this arrangement, only one pressure roller is required for every four spindles. This embodiment of the present invention makes it possible to save half of the pressure rollers compared to the prior art.

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.A fifth spindle and a sixth spindle are preferably arranged next to the fourth spindle and the centers of the bores of the fifth spindle and the sixth spindle lie on the straight spindle. Between the fifth spindle and the sixth spindle, a resiliently mounted second pressure roller can be arranged, which the tangential belt against the whorls of the fifth spindle and the sixth spindle presses.

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 are arranged in the manner described, the result is 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 ersten 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 can preferably be attached to the spindle bench between the third spindle and the fourth spindle. A common fastening of the first and second pressure rollers at a fastening point on the spindle bench 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.In addition to the spindle rail, the ring spinning machine also has a ring rail with bores for attaching spinning rings. A first spinning ring is assigned to the first spindle, a second spinning ring is assigned to the second spindle and a third spinning ring is assigned to the third spindle. The centers of the bores of the first spinning ring and of the second spinning ring are preferably on a straight line of the spinning ring and the center of the bore of the third spinning ring is spaced from the straight line of the spinning ring, the distance of the center of the bore of the third spinning ring from the straight line of the spinning ring being the distance of the center of the bore corresponds to the third spindle from 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 adapting the ring rail as described, the spinning rings and the spindles can be centered in a simple manner. If further spindles are offset or the corresponding bores in the spindle bank, the bores of the spinning rings in the ring bank 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, if a fourth spindle is designed as described above and a fourth spinning ring is assigned to the fourth spindle, the center of the bore of the fourth spinning ring in the ring rail can be spaced from the spinning ring line corresponding to the center of the bore of the third spinning ring. The fifth and A fifth and sixth spinning ring can be assigned to the sixth spindle. The centers of the bores of the fifth and sixth spinning ring in the ring rail can then again lie on the straight line of the spinning ring.

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 arrangement according to the invention can be used in conjunction with known ring spinning machines without further adaptations being required. Thread guide elements of the ring spinning machine, such as the thread guide and balloon constriction ring, are centered on the axis of the spindle anyway.

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 doffing devices can also be used in connection with the spindle device according to the invention. The offset of the spindles can be selected to be significantly smaller than the catching range of the grippers of the doffing device.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below using an exemplary embodiment shown in the drawings.

The center of the bore 15 of the spindle 33 is arranged at a distance from the straight line 40, the center of the bore 15 of the spindle 33 and the pressure roller 41 being on the same side of the straight line 40. The tangential belt 6 thus rests against the whorl 12 of the spindle 33 with sufficient pressure. At the in Fig. 2 The illustrated embodiment repeats the described spindle arrangement in the longitudinal direction of the ring spinning machine 1. That is, the centers of the bores 15 of the spindles 31 'and 32' also lie on the straight line 40. A pressure roller 41 'is arranged between the spindles 31' and 32 ', which presses the tangential belt 6 against the whorls 12 of the spindles 31 'and 32'. The For this purpose, the pressure roller 41 'is subjected to a pressure force by means of the leaf spring 51'. The leaf spring 51 ′ is fastened to the spindle bank 14 by means of the fastening element 52 ′. The center of the bore 15 of the spindle 33 ′ is arranged at a distance from the straight line 40, the center of the bore 15 of the spindle 33 ′ and the pressure roller 41 ′ being on the same side of the straight line 40. In the Fig. 2 The illustrated embodiment reduces the number of pressure rollers required by a third compared to the prior art. According to the prior art, a pressure roller is assigned to two spindles. The embodiment shown requires a pressure roller for three spindles.

Die Fig. 3 zeigt eine Draufsicht einer alternativen Ausführungsform der Spindelbank 14 der erfindungsgemäßen Ringspinnmaschine 1. Die Spindeln 31, 32 und 33 sind entsprechend der Ausführungsform der Fig. 2 angeordnet und tragen deshalb auch gleiche Bezugszeichen. Die Anpressrolle 41 ist zwischen den Spindeln 31 und 32 angeordnet und drückt den Tangentialriemen gegen die Wirtel 12 der beiden Spindeln 31 und 32. Die Spindel 34 ist neben der Spindel 33 angeordnet. Der Mittelpunkt der Bohrung 15 der Spindel 34 ist entsprechend dem Mittelpunkt der Bohrung 15 der Spindel 33 beabstandet zu der Geraden 40. Die neben der Spindel 34 folgenden Spindeln 35 und 36 sind dann wieder so angeordnet, dass die Mittelpunkte ihrer Bohrungen 15 wieder auf der Geraden 40 liegen, auf der auch die Mittelpunkte der Bohrungen 15 der Spindeln 31 und 32 liegen. Die Anpressrolle 42 drückt den Tangentialriemen 6 gegen die Wirtel 12 der Spindeln 35 und 36. Die Anpressrollen 41 und 42 sind mittels der Blattfedern 43 und 44 beaufschlagt. Die Blattfedern sind über ein gemeinsames Befestigungselement 45 an der Spindelbank 14 befestigt. Die Befestigung erfolgt zwischen den Spindeln 33 und 34. Neben der Spindel 36 sind zwei weitere Spindeln 37 und 38 angeordnet. Die Mittelpunkte der Bohrungen 15 der Spindeln 37 und 38 sind dann wieder entsprechend der Mittelpunkte der Bohrungen 15 der Spindeln 33 und 34 von der Geraden 40 beabstandet. Die Anordnung aus den acht Spindeln 31, 32, 33, 34, 35, 36, 37, 38 wiederholt sich in Längsrichtung der Ringspinnmaschine 1. Die Spindelanordnung der Fig. 3 ermöglicht im Vergleich zum Stand der Technik, die Hälfte der Anpressrollen einzusparen. Es ist jeweils für vier Spindeln nur eine Anpressrolle erforderlich.The Fig. 3 shows a plan view of an alternative embodiment of the spindle bank 14 of the ring spinning machine 1 according to the invention. The spindles 31, 32 and 33 are corresponding to the embodiment of FIG Fig. 2 arranged and therefore also have the same reference numerals. The pressure roller 41 is arranged between the spindles 31 and 32 and presses the tangential belt against the whorls 12 of the two spindles 31 and 32. The spindle 34 is arranged next to the spindle 33. The center of the bore 15 of the spindle 34 is spaced from the straight line 40 corresponding to the center of the bore 15 of the spindle 33. The spindles 35 and 36 following next to the spindle 34 are then arranged again so that the centers of their bores 15 are again on the straight line 40, on which the centers of the bores 15 of the spindles 31 and 32 also lie. The pressure roller 42 presses the tangential belt 6 against the whorls 12 of the spindles 35 and 36. The pressure rollers 41 and 42 are acted upon by the leaf springs 43 and 44. The leaf springs are fastened to the spindle bank 14 via a common fastening element 45. The fastening takes place between the spindles 33 and 34. In addition to the spindle 36, two further spindles 37 and 38 are arranged. The center points of the bores 15 of the spindles 37 and 38 are then again spaced from the straight line 40 in accordance with the center points of the bores 15 of the spindles 33 and 34. The arrangement of the eight spindles 31, 32, 33, 34, 35, 36, 37, 38 is repeated in the longitudinal direction of the ring spinning machine 1. The spindle arrangement of the Fig. 3 makes it possible to save half of the pressure rollers compared to the prior art. Only one pressure roller is required for each four spindles.

Bei der Ringspinnmaschine 1 werden die Spinnringe 3, die Balloneinengungsringe 4 und wandernden Fadenführer 5 zu der Spindel 11 zentriert. Bei den Balloneinengungsringen 4 und wandernden Fadenführern 5 erfolgt dies in bekannter Weise durch eine Justierung an jeder Spinnstelle 2. Um die Spinnringe 3 entsprechend zu zentrieren, erfolgt vorzugsweise ein Versatz der Bohrungen 7 in der Ringbank 8 entsprechend dem Versatz der Bohrungen 15 in der Spindelbank.In the case of the ring spinning machine 1, the spinning rings 3, the balloon constriction rings 4 and the traveling thread guides 5 are centered on the spindle 11. At the balloon constriction rings 4 and wandering thread guides 5, this is done in a known manner by an adjustment at each spinning station 2. To center the spinning rings 3 accordingly, the holes 7 in the ring rail 8 are preferably offset according to the offset of the holes 15 in the spindle rail.
