Description

Die Erfindung betrifft einen Antrieb für Webschäfte einer Webmaschine mit Antriebselementen, die Rotationsbewegungen in lineare Bewegungen umformen und die in einem Gehäuse angeordnet sind, das ein Hebelsystem aufnimmt, das die linearen Bewegungen als Auf- und Abbewegungen auf die Webschäfte überträgt. Ein solchen Antrieb ist vom EP 0 742 298 A1 (1996-11-13 ) bekannt.The invention relates to a drive for weaving shafts of a weaving machine with drive elements that transform rotational movements into linear movements and which are arranged in a housing which receives a lever system that transmits the linear movements as up and down movements on the heddle shafts. Such a drive is from EP 0 742 298 A1 (1996-11-13 ) known.

Ein Antrieb der eingangs genannten Art ist ungleichförmigen Belastungen ausgesetzt, da er die Webschäfte während eines Webzyklus anheben und absenken muss. Dies führt zu einer beträchtlichen Belastung des Antriebsmotors, insbesondere wenn der Antriebsmotor unabhängig von dem Hauptantriebsmotor der Webmaschine ist. Der Erfindung liegt die Aufgabe zugrunde, einen Antrieb der eingangs genannten Art so auszubilden, dass der Antriebsmotor nicht überlastet wird.A drive of the type mentioned is exposed to non-uniform loads, since he has to raise and lower the healds during a weaving cycle. This leads to a considerable load of the drive motor, in particular when the drive motor is independent of the main drive motor of the loom. The invention has the object of providing a drive of the type mentioned in such a way that the drive motor is not overloaded.

Diese Aufgabe wird dadurch gelöst, dass der Antrieb ein oder mehrere Kühlkanäle vorgesehen sind, die an einen Bereich des Gehäuses angeschlossen sind, der zur Aufnahme eines Ölbades dient.This object is achieved in that the drive one or more cooling channels are provided, which are connected to a region of the housing, which serves to receive an oil bath.

Das Öl des Ölbades, das als Schmiermittel für die in dem Gehäuse des Antriebs angeordneten Antriebselemente dient, wird in vorteilhafter Weise zur Kühlung herangezogen. Darüber hinaus wird die Gefahr vermieden, dass das Gehäuse und damit auch die Antriebselemente ungleichmäßig aufgewärmt werden, so dass thermische Verformungen vermieden werden, die sonst zu Ausrichtungsproblemen insbesondere bezüglich Antriebsstangen oder Lagerungen führen könnten.The oil of the oil bath, which serves as a lubricant for the arranged in the housing of the drive drive elements, is used advantageously for cooling. In addition, the risk is avoided that the housing and thus the drive elements are heated unevenly, so that thermal deformations are avoided, which could otherwise lead to alignment problems, especially with respect to drive rods or bearings.

In Ausgestaltung der Erfindung wird vorgesehen, dass an dem Gehäuse ein Antriebsmotor ist, der mit einem Kühlkanal umgeben ist.In an embodiment of the invention it is provided that on the housing is a drive motor which is surrounded by a cooling channel.

Um sicherzustellen, dass eine ausreichende Ölzufuhr zur Kühlung des Gehäuses und insbesondere des Antriebsmotors erhalten wird, wird in weiterer Ausgestaltung der Erfindung vorgesehen, dass eine zu dem Antriebsmotor führende Ölzuführleitung an eine Ölpumpe angeschlossen ist. Dabei kann vorteilhaft eine Ölpumpe vorgesehen werden, die die Lagerstellen oder Gelenkstellen der in dem Gehäuse angeordneten Antriebselement mit Öl versorgt, insbesondere durch Aufsprühen von Öl.To ensure that a sufficient supply of oil for cooling the housing and in particular of the drive motor is obtained, it is provided in a further embodiment of the invention that an oil supply line leading to the drive motor is connected to an oil pump. In this case, advantageously, an oil pump can be provided, which supplies the bearings or joints of the arranged in the housing drive element with oil, in particular by spraying oil.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass das Gehäuse sich von einer Seite der Webmaschine zur gegenüberliegenden Seite erstreckt, dass der Antriebsmotor im Bereich eines Endes des Gehäuses angebracht ist, und dass eine Ölrücklaufleitung im Bereich des anderen Endes in das Gehäuse mündet. Damit wird erreicht, dass eine möglichst gleichmäßige Erwärmung des Gehäuses und der darin untergebrachten Antriebselemente mittels der von dem Antriebsmotor abgegebenen Wärme erhalten wird.In a further embodiment of the invention it is provided that the housing extends from one side of the weaving machine to the opposite side, that the drive motor is mounted in the region of one end of the housing, and that an oil return line in the region of the other end opens into the housing. This ensures that the most uniform possible heating of the housing and the drive elements housed therein is obtained by means of the heat emitted by the drive motor.

Um die Wärme abzuführen, wird bei einer Ausführungsform der Erfindung vorgesehen, dass das Gehäuse vorzugsweise in der Nähe seines Bodens mit Kühlrippen oder Kühlelementen versehen ist. Bei einer anderen Ausführungsform wird vorgesehen, dass in der Ölzuführleitung oder in der Ölrücklaufleitung ein Ölkühler angeordnet ist. Vorzugsweise kühlt der Ölkühler mit einem flüssigen Kühlmittel, insbesondere Kühlwasser.In order to dissipate the heat, it is provided in one embodiment of the invention that the housing is preferably provided in the vicinity of its bottom with cooling fins or cooling elements. In another embodiment it is provided that in the oil supply or in the oil return line, an oil cooler is arranged. The oil cooler preferably cools with a liquid coolant, in particular cooling water.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass das Gehäuse gegebenenfalls mit dem Antriebsmotor, mit der Ölpumpe, mit der Ölzuführleitung und mit der Ölrücklaufleitung als eine an eine Webmaschine anbaubare Baueinheit ausgebildet ist. Diese Baueinheit wird beispielsweise bei einem Hersteller vorgefertigt und dann als Baueinheit an einer Webmaschine angebracht. Wenn das Anbringen unter Verwendung von Dämpfungselementen erfolgt, so wird sichergestellt, dass zwischen dem Schaftantrieb und der Webmaschine keine Vibrationen oder Schwingungen hin- und herübertragen werden.In a further embodiment of the invention it is provided that the housing is optionally formed with the drive motor, with the oil pump, with the oil supply and with the oil return line as an attachable to a loom assembly. This unit is prefabricated, for example, at a manufacturer and then attached as a unit to a loom. When mounting using damping elements, it is ensured that no vibrations or oscillations are transmitted back and forth between the shaft drive and the weaving machine.

Der in Fig. 1 und 2 dargestellte Schaftantrieb besitzt ein langgestrecktes Gehäuse 10. Das Gehäuse 10 erstreckt sich mit einem im wesentlichen einen rechteckigen Querschnitt aufweisenden Teil zwischen den Seitenteilen 11, 12 einer Webmaschine. In einem außerhalb eines Seitenteils, beispielsweise des linken Seitenteils 11 liegenden Bereich besitzt das Gehäuse 10 einen vergrößerten Bereich 13. In diesem Bereich 13 ist eine Antriebswelle 14 untergebracht, die über ein Hebelsystem 15 mit Übertragungselementen 16 verbunden ist, die in dem Bereich zwischen den Seitenteilen 11, 12 nach oben aus dem Gehäuse 10 herausragen und mit Webschäften 17 verbunden sind, die zu Auf- und Abbewegungen angetrieben werden.The shaft drive shown in Fig. 1 and 2 has an elongated housing 10. The housing 10 extends with a substantially rectangular section having part between the side parts 11, 12 of a loom. In a region located outside of a side part, for example of the left side part 11, the housing 10 has an enlarged area 13. In this area 13 a drive shaft 14 is accommodated, which is connected via a lever system 15 to transmission elements 16 which are in the area between the side parts 11, 12 protrude upward from the housing 10 and are connected to Webschäften 17, which are driven to up and down movements.

Die Antriebswelle 14 wird mittels eines von einem Hauptantriebsmotor einer Webmaschine unabhängigen Antriebsmotor 18 angetrieben, der an ein Getriebegehäuse 19 angeflanscht ist, das seinerseits an das Gehäuse 10 in dem vergrößerten Bereich außerhalb des Seitenteils 11 angeflanscht ist. Das Getriebegehäuse 19 enthält eine Getriebestufe, die den Antriebsmotor 18 mit der Antriebswelle 14 verbindet. Das Getriebegehäuse 19 kann auch mit dem Gehäuse 10 einteilig sein.The drive shaft 14 is driven by means of a drive motor 18 independent of a main drive motor of a weaving machine, which is flanged to a transmission housing 19, which in turn is flanged to the housing 10 in the enlarged area outside of the side part 11. The transmission housing 19 includes a gear stage which connects the drive motor 18 to the drive shaft 14. The transmission housing 19 may also be integral with the housing 10.

Das Gehäuse 10 ist insgesamt abgedichtet und nimmt ein Ölbad 20 auf. Im Bereich der Übertragungselemente 16 befinden sich Abdichtelemente 21, die sicherstellen, dass einerseits kein Staub in das Gehäuse 10 eindringt und andererseits kein Öl in den Bereich des entstehenden Gewebes gelangt.The housing 10 is sealed altogether and receives an oil bath 20. In the area of the transmission elements 16 there are sealing elements 21 which ensure that, on the one hand, no dust penetrates into the housing 10 and, on the other hand, no oil gets into the region of the resulting tissue.

Da der Antriebsmotor 18 hohen Belastungen und insbesondere auch hohen thermischen Belastungen ausgesetzt ist, wird für ihn eine Ölkühlung vorgesehen, die das Öl des Ölbades 20 benutzt. An das Ölbad 20 ist eine Ölpumpe 22 angeschlossen, die über eine Ölzuführleitung 23 mit einem oder mehreren den Antriebsmotor mantelartig umgebenden Kühlkanälen verbunden ist. An diese Kühlkanäle des Antriebsmotors 18 schließt eine Ölrücklaufleitung 24 an, durch die das Öl nach Verlassen des Antriebsmotors 18 zu dem Gehäuse 10 und in das Ölbad 20 zurückgeführt wird. Diese Ölrücklaufleitung 24 mündet in dem dem vergrößerten Bereich 13 gegenüberliegenden Bereich des Endes des Gehäuses 10. Bei dem Ausführungsbeispiel ist innerhalb der Ölrücklaufleitung ein Ölkühler 25 vorgesehen, der das von dem Antriebsmotor 18 zurückfließende Öl kühlt.Since the drive motor 18 is exposed to high loads and in particular high thermal loads, an oil cooling is provided for him, which uses the oil of the oil bath 20. To the oil bath 20 an oil pump 22 is connected, which is connected via an oil feed 23 with one or more the drive motor mantle-like surrounding cooling channels. To these cooling channels of the drive motor 18 includes an oil return line 24, through which the oil is returned after leaving the drive motor 18 to the housing 10 and into the oil bath 20. This oil return line 24 opens in the region of the end of the housing 10 opposite the enlarged region 13. In the exemplary embodiment, an oil cooler 25 is provided inside the oil return line, which cools the oil flowing back from the drive motor 18.

Die Ölpumpe 22 wird zweckmäßiger Weise auch dazu ausgenutzt, dass das Öl als Schmiermittel den einzelnen Lagerelementen des Hebelsystems 15 des Schaftantriebs zugeführt wird, wie das mit der Leitung 26 in Fig. 1 angedeutet ist. Wie in Fig. 1 mit gestrichelter Linie angedeutet ist, kann die Ölrücklaufleitung 24 mit dieser Leitung verbunden sein, so dass die Lagerstellen der Antriebsmittel mit erwärmten Öl geschmiert werden.The oil pump 22 is expediently also exploited to the fact that the oil is supplied as a lubricant to the individual bearing elements of the lever system 15 of the shaft drive, as indicated by the line 26 in Fig. 1. As indicated in dashed line in Fig. 1, the oil return line 24 may be connected to this line, so that the bearings of the drive means are lubricated with heated oil.

Bei einer bevorzugten Ausführungsform wird der gesamte Schaftantrieb als eine vorgefertigte Baueinheit ausgebildet, die als solche an einer Webmaschine angebracht werden kann. Hierzu sind Befestigungsflansche 27, 28 an dem Gehäuse 10 vorgesehen, mit denen die Baueinheit an den Seitenteilen 11, 12 der Webmaschine befestigt werden kann. Bei dieser Ausbildung wird dann insbesondere die Ölpumpe 22 innerhalb des Gehäuses 10 angeordnet. Zweckmäßigerweise wird sie mittels einer Getriebestufe mit der Antriebswelle 14 verbunden, so dass der Antriebsmotor 18 auch die Ölpumpe mit antreibt.In a preferred embodiment, the entire shaft drive is formed as a prefabricated unit, which can be attached as such to a loom. For this purpose, mounting flanges 27, 28 are provided on the housing 10, with which the assembly can be attached to the side parts 11, 12 of the loom. In this embodiment, in particular, the oil pump 22 is disposed within the housing 10. Conveniently, it is connected by means of a gear stage with the drive shaft 14, so that the drive motor 18 also drives the oil pump.

Der Schaftantrieb nach Fig. 1 ist nur als ein Beispiel dargestellt. Bei einer abgewandelten Ausführungsform wird die Antriebswelle 14 unmittelbar von dem Antriebsmotor 18 angetrieben. Der Antriebsmotor 18 kann auch an der Stirnseite oder der Oberseite oder der gegenüberliegenden Seite des vergrößerten Bereichs 13 des Gehäuses 10 angebracht werden. Gegebenenfalls wird eine Umlenk-Getriebestufe mittels Kegelrädern vorgesehen.The shaft drive of Fig. 1 is shown only as an example. In a modified embodiment, the drive shaft 14 is driven directly by the drive motor 18. The drive motor 18 can also be on the front side or the top or the opposite Side of the enlarged portion 13 of the housing 10 are attached. Optionally, a deflection gear stage is provided by means of bevel gears.

Mit der Erfindung soll insbesondere vermieden werden, dass das Gehäuse 10, das sich unterhalb der Kettfäden befindet, als eine Art Heizkörper wirkt. Aufgrund der Wirkung als Heizkörper könnten ansonsten die Kettfäden oberhalb des Gehäuses getrocknet werden, was einen nachteiligen Einfluss auf den Webvorgang und das erhaltene Gewebe haben könnte. Um die Wirkung als Heizkörper zu vermeiden, sollte in dem Gehäuse 10 möglichst wenig Öl vorhanden sein, d.h. nur ausreichend Öl für das Erzielen der Schmierwirkung. Vorzugsweise sollte darüber hinaus dieses Öl, das die Lagerelemente des Hebelsystems schmiert, gekühlt sein.With the invention is to be avoided in particular that the housing 10, which is located below the warp threads, acts as a kind of radiator. Due to the effect as a radiator otherwise the warp threads above the housing could be dried, which could have a detrimental effect on the weaving and the fabric obtained. In order to avoid the effect as a radiator, as little oil as possible should be present in the housing 10, i. only enough oil to achieve the lubricating effect. Preferably, moreover, this oil, which lubricates the bearing elements of the lever system, should be cooled.

Bei der Ausführungsform nach Fig. 3 und 4 ist deshalb vorgesehen, dass ein Ölbad 20' auf den Bereich 13 des Gehäuses 10 beschränkt ist, der sich außerhalb der Seitenteile 11, 12 der Webmaschine befindet. In diesem Bereich 13 hat das Gehäuse 10 einen tieferen Boden als in dem Bereich zwischen den Seitenteilen 11, 12. In diesem Bereich ist, wie das in Fig. 4 dargestellt ist, in dem Boden des Gehäuses 10 nur eine Rinne 31 vorgesehen, die als Rücklauf zu dem Ölbad 20' dient. In dem Bereich 13 des Gehäuses 10 ist ein Ölkühler 25 angeordnet, der über strichpunktiert dargestellte Versorgungsleitungen 32 Sprühdüsen 33 mit gekühltem Öl versorgt, die Lagerstellen des Hebelsystems 15 zugeordnet sind. Das ausgesprühte, gekühlte Öl fließt über die Rinne 31 zu dem Ölbad des Bereichs 13 des Gehäuses 10 zurück. Wie aus Fig. 4 zu ersehen ist, ist die Rinne 31 eine nach unten aus dem Boden des Gehäuses 10 ragende Rippe. Aufgrund dieser Formgebung wirkt die Rinne gleichzeitig als eine Kühlrippe.In the embodiment according to FIGS. 3 and 4, it is therefore provided that an oil bath 20 'is restricted to the region 13 of the housing 10 which is located outside the side parts 11, 12 of the weaving machine. In this area 13, the housing 10 has a lower floor than in the area between the side parts 11, 12. In this area, as shown in Fig. 4, in the bottom of the housing 10, only a groove 31 is provided which as Return to the oil bath 20 'is used. In the area 13 of the housing 10, an oil cooler 25 is arranged, which supplies 32 spray nozzles 33 with cooled oil, the bearing points of the lever system 15 are assigned via supply lines 32 shown in phantom. The sprayed, cooled oil flows back via the channel 31 to the oil bath of the area 13 of the housing 10. As can be seen from Fig. 4, the groove 31 is a downwardly projecting from the bottom of the housing 10 rib. Due to this shape, the gutter acts as a cooling rib at the same time.

Das Gehäuse 10 wird bei dem Ausführungsbeispiel nach Fig. 3 und 4 mittels Dämpfungselementen 34, 35 an den Seitenteilen 11, 12 der Webmaschine befestigt, die somit das Gehäuse 10 auch thermisch von den Seitenteilen 11, 12 trennen.The housing 10 is fastened in the embodiment according to FIGS. 3 and 4 by means of damping elements 34, 35 to the side parts 11, 12 of the loom, which thus also thermally separate the housing 10 from the side parts 11, 12.

Grundsätzlich kommen für die Erfindung jede Art von Schaftantrieben in Frage, d.h. ein Dobby, ein Nockenantrieb, ein Exenterantrieb oder ein Kurbelantrieb.In principle, any type of shaft drives are suitable for the invention, i. a dobby, a cam drive, an eccentric drive or a crank drive.

Bei abgewandelten Ausführungsformen sind für den Antrieb mehrere unabhängige Antriebsmotoren vorgesehen, die jeweils einer Anzahl von Webschäften oder jeweils einem einzelnen Webschaft zugeordnet sind. Wenigstens einer der Vielzahl dieser Antriebsmotoren und vorzugsweise alle diese Antriebsmotoren werden in der vorstehend erläuterten Weise gekühlt.In modified embodiments, a plurality of independent drive motors are provided for the drive, which are each assigned to a number of heddles or each a single weaving shank. At least one of the plurality of these drive motors and preferably all of these drive motors are cooled in the manner explained above.

In Fig. 5 und 6 ist eine Ausführungsform ähnlich Fig. 3 dargestellt, bei welcher im Bereich des Bodens des Gehäuses 10 ein Kühlkanal 40 vorgesehen ist, der bei diesem Ausführungsbeispiel die Rinnen 31 umgibt. In diesen Kühlkanal 40 wird eine Kühlmittelströmung erzeugt. Das kann gekühlte Luft sein. Die Luft wird bevorzugt mittels eines Gebläses durch den Kühlkanal 40 geblasen. Es ist jedoch auch möglich, eine Konvektionsströmung zu erzeugen. Bei einer anderen Ausführungsform wird ein flüssiges Kühlmittel durch den Kühlkanal 40 geführt. Dieses flüssige Kühlmittel, insbesondere Kühlwasser, kann mittels einer Pumpe zugeführt werden. Zweckmäßigerweise werden bei dieser Ausführungsform mehrere Rinnen 31 in dem Boden des Gehäuses 10 vorzugsweise in Form von Profilierungen vorgesehen, die in den Kühlkanal 40 ragen. Damit ist es möglich, die Kühlfläche zu vergrößern. Der Kühlkanal 40 wird von dem Boden des Gehäuses 10 und einem daran befestigten Profil 41 gebildet. Das Kühlfluid - Luft oder Kühlwasser - strömt in dem Kühlkanal von einem Seitenteil 12 zum Seitenteil 11. Das Kühlfluid wird im Bereich des Seitenteils 11 entnommen, durch einen Kühler 42 hindurch geführt und im Bereich des anderen Seitenteils 12 wieder zugeführt. Zu der Kühleinrichtung 42 kann gegebenenfalls auch ein Kälteaggregat gehören.In Fig. 5 and 6, an embodiment similar to Fig. 3 is shown, in which in the region of the bottom of the housing 10, a cooling channel 40 is provided which surrounds the grooves 31 in this embodiment. In this cooling channel 40, a flow of coolant is generated. This can be cooled air. The air is preferably blown through the cooling passage 40 by means of a blower. However, it is also possible to generate a convection flow. In another embodiment, a liquid coolant is passed through the cooling channel 40. This liquid coolant, in particular cooling water, can be supplied by means of a pump. Conveniently, in this embodiment, a plurality of grooves 31 are provided in the bottom of the housing 10, preferably in the form of profiles, which protrude into the cooling channel 40. This makes it possible to increase the cooling area. The cooling channel 40 is formed by the bottom of the housing 10 and a profile 41 attached thereto. The cooling fluid - air or cooling water - flows in the cooling channel from a side part 12 to the side part 11. The cooling fluid is removed in the region of the side part 11, through a cooler 42 therethrough guided and fed back in the area of the other side part 12. Optionally, the cooling device 42 may also include a refrigeration unit.
