Description

Die vorliegende Erfindung betrifft eine doppelseitige Ringspinnmaschine mit Streckwerken auf jeder Seite. Die Streckwerke umfassen jeweils eine Eingangsunterwalze, eine Mittelunterwalze und eine Ausgangsunterwalze. Den Eingangsunterwalzen ist ein erster Motor zugeordnet, den Mittelunterwalzen ist ein zweiter Motor zugeordnet und den Ausgangsunterwalzen ist ein dritter Motor zugeordnet. Der erste Motor ist über ein erstes Getriebe mit den Eingangsunterwalzen verbunden, der zweite Motor ist über ein zweites Getriebe mit den Mittelunterwalzen verbunden und der dritte Motor ist über ein drittes Getriebe mit den Ausgangsunterwalzen verbunden.The present invention relates to a double-sided ring spinning machine with drafting devices on each side. The drafting systems each include an input sub-roller, a middle sub-roller, and an output sub-roller. The input sub-rollers is assigned a first motor, the middle sub-rollers is assigned a second motor and the output sub-rollers is assigned to a third motor. The first motor is connected to the input sub-rollers via a first gear, the second motor is connected to the middle sub-rollers via a second gear, and the third motor is connected to the output sub-rollers via a third gear.

Die DE 10 2005 054 024 A1 offenbart eine Ringspinnmaschine mit Streckwerken, deren Eingangsunterwalzen, Mittelunterwalzen und Ausgangsunterwalzen jeweils durch einen eigenen Motor angetrieben werden. Jedem Motor ist ein eigenes Getriebe zugeordnet. Jedes Getriebe ist, um die Ringspinnmaschine gegen Austritt von Öl und Fett aus dem Getriebe zu sichern, in einem eigenen Getriebegehäuse untergebracht. Eine Ausführung mit separaten Motoren ermöglicht die einfache Einstellung verschiedener Verzüge zwischen den Walzenpaaren des Streckwerkes. Die Einstellung des Verzuges erfolgt auf einfache Weise durch eine Regelung der Drehzahl der Motoren. Die Montage eines solchen Antriebs gestaltet sich aufgrund der separaten Getriebe jedoch besonders aufwendig. Es bestehen hohe Anforderungen an die Genauigkeit der Montage und an die Parallelität der Achsen der einzelnen Getriebe. Die einzelnen Getriebe erfordern außerdem einen hohen Platzbedarf.The DE 10 2005 054 024 A1 discloses a ring spinning machine with drafting units whose input sub-rollers, middle sub-rollers and output sub-rollers are each driven by a separate motor. Each engine is assigned its own gearbox. Each gearbox is housed in a separate gearbox to secure the ring spinning machine against oil and grease leaks from the gearbox. A version with separate motors allows easy adjustment of various distortions between the roller pairs of the drafting system. The adjustment of the delay is done in a simple manner by controlling the speed of the motors. However, the assembly of such a drive is particularly complicated due to the separate transmission. There are high demands on the accuracy of the assembly and on the parallelism of the axes of the individual gear. The individual gears also require a lot of space.

Die DE 101 37 140 C1 offenbart eine Ringspinnmaschine mit Streckwerken auf beiden Seiten. Die Eingangsunterwalzen und die Mittelunterwalzen weisen hier einen gemeinsamen Antrieb mit gemeinsamen Motoren auf. Die Konstruktion des Antriebes wird einfacher. Die Einstellung des Vorverzuges ist jedoch nur noch durch einen Wechsel von Zahnrädern des Getriebes möglich.The DE 101 37 140 C1 discloses a ring spinning machine with drafting devices on both sides. The input sub-rollers and the middle sub-rollers have here a common drive with common motors. The construction of the drive becomes easier. The adjustment of the pre-delay is only possible by a change of gears of the transmission.

Darüber hinaus sind Streckwerke bekannt mit einem gemeinsamen Antrieb für die Eingangsunterwalzen, die Mittelunterwalzen und die Ausgangsunterwalzen. Der Antrieb umfasst in der Regel einen Motor und ein gemeinsames Getriebe für alle Unterwalzen.In addition, drafting systems are known with a common drive for the input sub-rollers, the middle sub-rollers and the output sub-rollers. The drive usually includes a motor and a common transmission for all lower rollers.

Es ist die Aufgabe der vorliegenden Erfindung, den Antrieb für das Streckwerk einer doppelseitigen Ringspinnmaschine mit separaten Motoren für die Eingangsunterwalzen, die Mittelunterwalzen und die Ausgangsunterwalzen zu verbessern.It is the object of the present invention to improve the drive for the drafting system of a double-sided ring spinning machine with separate motors for the input sub-rollers, the middle sub-rollers and the output sub-rollers.

Zur Lösung der Aufgabe sind das erste Getriebe, das zweite Getriebe und das dritte Getriebe in einem gemeinsamen Getriebegehäuse angeordnet. Die Anordnung der funktional unabhängigen Getriebe der Eingangsunterwalzen, der Mittelunterwalzen und der Ausgangsunterwalzen in einem Getriebegehäuse hat eine Reihe von Vorteilen. Die Zusammenfassung in einem Gehäuse vereinfacht die Montage an der Ringspinnmaschine. Die genaue parallele Ausrichtung der Achsen der drei Getriebe kann unabhängig von der Ringspinnmaschine erfolgen. Durch die Anordnung der Getriebe in einem einzigen Getriebegehäuse kann der Bauraum besser ausgenutzt werden. Die Anordnung wird insgesamt kompakter. Damit wird auch die Handhabung bei der Montage vereinfacht.To solve the problem, the first transmission, the second transmission and the third transmission are arranged in a common transmission housing. The arrangement of the functionally independent gears of the input sub-rollers, the center sub-rollers and the output sub-rollers in a gearbox has a number of advantages. The summary in a housing simplifies the assembly on the ring spinning machine. The exact parallel alignment of the axes of the three gears can be done independently of the ring spinning machine. The arrangement of the transmission in a single gear housing, the space can be better utilized. The arrangement becomes more compact overall. This also simplifies handling during installation.

Vorzugsweise ist das gemeinsame Getriebegehäuse zur Aufnahme eines Schmierstoffes zur gemeinsamen Schmierung des ersten Getriebes, des zweiten Getriebes und des dritten Getriebes ausgebildet. Als Schmierstoff kommt insbesondere Öl in Betracht. Die gemeinsame Schmierung reduziert nicht nur den Gesamtaufwand für die Schmierung; es wird auch die Wärmeabfuhr und die thermische Ausnutzung verbessert. Um die gewünschten Verzüge zu realisieren, werden die Ausgangsunterwalzen mit einer deutlich höheren Drehzahl beaufschlagt als die Eingangs- und Mittelunterwalzen. Deshalb wird über das dritte Getriebe eine deutlich höhere Leistung übertragen. Der Schmierstoff wird durch das dritte Getriebe also deutlich stärker erwärmt. Durch die gemeinsame Schmierung findet damit ein Temperaturausgleich statt.Preferably, the common transmission housing for receiving a lubricant for common lubrication of the first transmission, the second transmission and the third transmission is formed. As a lubricant is especially oil into consideration. The common lubrication not only reduces the overall expense of lubrication; It also improves the heat dissipation and thermal utilization. In order to realize the desired distortions, the output lower rollers are subjected to a much higher speed than the input and middle lower rollers. Therefore, a significantly higher power is transmitted via the third gear. The lubricant is therefore heated much more strongly by the third gear. Due to the common lubrication, a temperature compensation takes place.

Im Zusammenhang mit der vorliegenden Erfindung können verschiedene an sich bekannte Schmierungsverfahren zur Anwendung kommen. So kann das Getriebegehäuse zur Durchführung einer Tauchschmierung ausgebildet sein. Alternativ kann das Getriebegehäuse Mittel zur Durchführung einer Umlaufschmierung aufweisen.Various lubrication methods known per se may be used in connection with the present invention. Thus, the transmission housing may be designed to carry out a splash lubrication. Alternatively, the transmission housing may comprise means for performing a circulation lubrication.

Gemäß einer bevorzugten Ausführungsform tritt aus dem Getriebegehäuse für jede Seite der Ringspinnmaschine jeweils eine Abtriebsstelle des ersten Getriebes, des zweiten Getriebes und des dritten Getriebes aus.According to a preferred embodiment, an output point of the first transmission, of the second transmission and of the third transmission emerges from the transmission housing for each side of the ring spinning machine.

Vorzugsweise sind die Abtriebsstellen des ersten Getriebes mit den Eingangsunterwalzen und die Abtriebsstellen des zweiten Getriebes mit den Mittelunterwalzen über Gelenkwellen verbunden. Damit wird auch bei vorgegebenen, nicht veränderbaren Abtriebsstellen an dem Getriebegehäuse eine einfache Verstellung der Feldweiten ermöglicht. Das heißt, die Abstände der Unterwalzenstränge können verändert werden.Preferably, the output points of the first gear are connected to the input sub-rollers and the output points of the second gear to the middle sub-rollers via drive shafts. This allows a simple adjustment of the field widths even at predetermined, unchangeable output points on the gear housing. That is, the distances of the lower roller strands can be changed.

Gemäß einer vorteilhaften Weiterbildung tritt aus dem Getriebegehäuse eine erste und eine zweite Antriebsstelle des ersten Getriebes aus, und der erste Motor ist zur Realisierung unterschiedlicher Übersetzungsverhältnisse wahlweise an die erste oder die zweite Antriebsstelle des ersten Getriebes anschließbar. Entsprechend können aus dem Getriebegehäuse eine erste und eine zweite Antriebsstelle des zweiten Getriebes austreten, und der zweite Motor ist zur Realisierung unterschiedlicher Übersetzungsverhältnisse wahlweise an die erste oder die zweite Antriebsstelle des zweiten Getriebes anschließbar. Die unterschiedlichen Übersetzungsverhältnisse dienen dazu, die Drehzahlen der Unterwalzen und damit die Verzüge des Streckwerkes in größeren Bereichen anzupassen zu können, als dies durch die Regelung der Drehzahlen der Motoren sinnvoll möglich ist. Vorzugsweise dienen die Antriebsstellen mit unterschiedlichem Übersetzungsverhältnis dazu, um für verschiedene Maschinentypen mit unterschiedlichen Verzugsbereichen das gleiche Getriebe verwenden zu können. Ein späterer Umbau bleibt natürlich möglich.According to an advantageous development of the transmission housing exits from a first and a second drive point of the first transmission, and the first motor can be connected to the realization of different ratios either to the first or the second drive point of the first transmission. Accordingly, a first and a second drive point of the second transmission can emerge from the transmission housing, and the second motor can be selectively connected to the realization of different transmission ratios to the first or the second drive point of the second transmission. The different gear ratios are used to be able to adjust the speeds of the lower rollers and thus the delays of the drafting in larger areas than is reasonably possible by regulating the speeds of the motors. Preferably, the drive units with different transmission ratio are used to be able to use the same transmission for different types of machines with different warpage areas. A later conversion remains of course possible.

Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Ringspinnmaschine tritt aus dem Getriebegehäuse eine erste und eine zweite Antriebsstelle des dritten Getriebes aus und der dritte Motor ist an die erste Antriebsstelle des dritten Getriebes angeschlossen und ein vierter Motor ist zur Erhöhung der übertragenen Leistung an die zweite Antriebsstelle des dritten Getriebes angeschlossen. Diese Ausführungsform wird dem Sachverhalt gerecht, dass aufgrund der höheren Drehzahl der Ausgangsunterwalzen eine größere Leistung für die Ausgangsunterwalzen bereitgestellt werden muss. Dabei wird vorteilhafterweise die bereitzustellende Leistung auf zwei Motoren verteilt, so dass jeder Seite der Ringspinnmaschine ein Motor zum Antrieb der Ausgangsunterwalzen zugeordnet wird.According to a preferred embodiment of the ring spinning machine according to the invention exits from the gear housing, a first and a second drive point of the third gear and the third motor is connected to the first drive point of the third gear and a fourth motor is to increase the transmitted power to the second drive point of the third Gearbox connected. This embodiment does justice to the fact that, because of the higher speed of the output sub-rollers, greater power must be provided for the output sub-rollers. In this case, the power to be provided is advantageously distributed to two motors, so that each side of the ring spinning machine is assigned a motor for driving the output lower rollers.

Gemäß einer vorteilhaften Ausführungsform der erfindungsgemäßen Ringspinnmaschine sind das Getriebegehäuse und die Motoren in einen gemeinsamen Rahmen montiert. Aus dem Rahmen ragt eine Verbindung zu den Eingangsunterwalzen, den Mittelunterwalzen und den Ausgangsunterwalzen heraus. Ein solcher Rahmen erleichtert die Montage. Außerdem vereinfacht ein solcher Rahmen die Herstellung von Maschinenvarianten, da der Rahmen auch mit anderen Antrieben bestückt werden kann. Der Rahmen schafft eine definierte Schnittstelle zu der Maschine. Der Rahmen kann beispielsweise auch mit einem gemeinsamen Getriebe für alle Unterwalzen und einem einzelnen Motor entsprechender Leistung ausgestattet werden.According to an advantageous embodiment of the ring spinning machine according to the invention, the gear housing and the motors are mounted in a common frame. Out of the frame protrudes a connection to the input sub-rollers, the middle sub-rollers and the output sub-rollers. Such a framework facilitates assembly. In addition, such a framework simplifies the production of machine variants, since the frame can also be equipped with other drives. The frame creates a defined interface to the machine. For example, the frame can also be equipped with a common transmission for all lower rollers and a single motor of corresponding power.

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.

Die Mittelunterwalzen 4 werden über die Wellen der Mittelunterwalzenstränge 7, 7' und das Getriebe 15 von dem Motor 11 angetrieben. In dem vorliegenden Ausführungsbeispiel werden die Ausgangsunterwalzen 5 von zwei Motoren 12 und 13 angetrieben. Es ist natürlich auch möglich, die Ausgangsunterwalzen 5 durch einen einzelnen Motor größerer Leistung anzutreiben. Die Motoren 12 und 13 sind über das Getriebe 16 mit den Wellen der Ausgangsunterwalzenstränge 8 und 8' verbunden und treiben die Ausgangsunterwalzen 5 an. Erfindungsgemäß sind die Getriebe 14, 15 und 16 in einem gemeinsamen Getriebegehäuse 9 untergebracht.The Fig. 1 shows a double-sided ring spinning machine according to the invention 1.

Getriebe erfordern in der Regel eine Schmierung mittels eines Schmierstoffes, insbesondere eines Schmieröls. Zur Schmierung sind verschiedene Verfahren bekannt. Zum Beispiel kann die Schmierung eines Getriebes mittels einer Tauchschmierung erfolgen. Das heißt, die unteren Getriebezahnräder sind ständig in das Öl einer Ölwanne getaucht. Durch die Drehung der Getriebezahnräder während des Betriebes erfolgt gegebenenfalls der Weitertransport zu den anderen Getriebezahnrädern. Eine weitere Möglichkeit der Schmierung von Getrieben ist eine Umlaufschmierung. Dazu kann beispielsweise eine Tropfwanne oberhalb des Getriebes angeordnet sein. Das Öl wird auf die Getriebezahnräder getropft und in einer Ölwanne unterhalb des Getriebes aufgefangen und dann wieder zurück in die Tropfwanne befördert. Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung erfolgt die Schmierung der drei funktional unabhängigen Getriebe 14, 15 und 16 gemeinsam. Das heißt, es wird nur eine Ölwanne, eine Tropfwanne oder eine Beförderungseinrichtung benötigt. Es gibt keine getrennten Ölbehälter beziehungsweise keine getrennten Ölkreisläufe für die Getriebe 14,15 und 16.Gearboxes usually require lubrication by means of a lubricant, in particular a lubricating oil. For lubrication, various methods are known. For example, the lubrication of a transmission can be done by means of splash lubrication. That is, the lower gear wheels are constantly immersed in the oil of an oil pan. By the rotation of the transmission gears during operation, if necessary, the further transport to the other transmission gears. Another way of lubricating gearboxes is a circulation lubrication. For this purpose, for example, a drip tray can be arranged above the transmission. The oil is dripped onto the transmission gears and collected in an oil pan below the transmission and then transported back into the drip tray. According to a preferred embodiment of the present invention, the lubrication of the three functionally independent transmissions 14, 15 and 16 takes place together. That is, only one sump, one drip tray or conveyor is needed. There are no separate oil reservoirs or separate oil circuits for the gears 14,15 and 16.
