Abstract
Description
Die Erfindung betrifft einen Antrieb für Webschäfte einer Webmaschine.The invention relates to a drive for heddle shafts of a loom.
Der Antrieb von Webschäften für eine Webmaschine wird üblicherweise von einem Hauptantriebsmotor abgeleitet, der eine Hauptantriebswelle antreibt, die ihrerseits eine Weblade antreibt. Zum Antrieb der Webschäfte wird ein Getriebe benötigt, das meist in ein Seitenteil des Rahmens der Webmaschine integriert ist und das die Antriebsbewegung auf ein Dobby, einen Nockenantrieb, einen Exzentermotorantrieb, eine Schaftmaschine oder einen Kurbelwellenantrieb überträgt, der mittels Schubstangen und Übertragungselementen mit den Webschäften verbunden ist.Web sheave drive for a weaving machine is usually derived from a main drive motor which drives a main drive shaft, which in turn drives a sley. To drive the heddle shafts a gear is required, which is usually integrated into a side part of the frame of the weaving machine and transmits the drive movement to a dobby, a cam drive, an eccentric motor drive, a dobby or a crankshaft drive connected by means of push rods and transmission elements with the heddle is.
Bei einer bekannten Bauart (
Der Erfindung liegt die Aufgabe zugrunde, einen Antrieb der eingangs genannten Art zu verbessern.The invention has for its object to improve a drive of the type mentioned.
Diese Aufgabe wird dadurch gelöst, dass wenigstens ein Antriebsmotor, Antriebselemente, die Rotationsbewegungen des Antriebsmotors in lineare Bewegungen umformen, und Übertragungselemente, die mit Webschäften verbunden sind, als eine Baueinheit ausgebildet sind.This object is achieved in that at least one drive motor, drive elements, the rotational movements of the drive motor in linear Forming movements, and transmission elements, which are connected to Webschäften, are designed as a structural unit.
Der erfindungsgemäße Antrieb für Webschäfte bildet eine Baueinheit und ist deshalb unabhängig von der Webmaschine herstellbar und auf seine Funktionsfähigkeit überprüfbar, bevor er mit der Webmaschine zusammengebaut wird. Da zwischen dem Antrieb der Webmaschine und dem Antrieb für die Schäfte keine Kräfte übertragen werden, muss der Konstrukteur einer Webmaschine nur berücksichtigen, dass ausreichend Platz für den Antrieb der Webschäfte zur Verfügung steht. Darüber hinaus muss er wenig Rücksicht auf die Gestaltung des Antriebs der Webschäfte nehmen. Es können an einer im übrigen gleichen Webmaschine unterschiedliche Antriebe für die Webschäfte vorgesehen werden, beispielsweise eine Schaftmaschine, ein Dobby, ein Nockenantrieb, ein Exzenterantrieb oder ein Kurbelantrieb. Der Antrieb für die Webschäfte kann für eine Reparatur oder einen Ersatz ausgetauscht werden, so dass die Stillstandszeiten einer Webmaschine verkürzt werden können.The drive for heald shafts according to the invention forms a structural unit and can therefore be produced independently of the weaving machine and can be tested for its functionality before it is assembled with the weaving machine. Since no forces are transmitted between the drive of the weaving machine and the drive for the shafts, the designer of a loom only needs to take into account that there is sufficient space for the drive of the heald frames available. In addition, he must take little account of the design of the drive of the heald frames. It can be provided on a rest in the same loom different drives for the heddle shafts, such as a dobby, a dobby, a cam drive, an eccentric or a crank drive. The drive for the heald frames can be replaced for a repair or a replacement, so that the downtime of a loom can be shortened.
In Ausgestaltung der Erfindung wird vorgesehen, dass die Baueinheit eine Tragkonstruktion besitzt, welche den Antriebsmotor, die Antriebselemente und die Übertragungselemente aufnimmt und die mit Einrichtungen zum Befestigen an einem Rahmen einer Webmaschine versehen ist. Die Befestigung kann über Dämpfungselemente, beispielsweise gummielastische Blöcke, erfolgen, da keine Antriebskräfte zu übertragen sind. Dadurch können gegenseitige Beeinflussungen durch Vibrationen oder Schwingungen vermieden werden.In an embodiment of the invention it is provided that the assembly has a support structure which receives the drive motor, the drive elements and the transmission elements and which is provided with means for attachment to a frame of a loom. The attachment can be done via damping elements, such as rubber-elastic blocks, since no driving forces are to be transmitted. As a result, mutual influences by vibrations or vibrations can be avoided.
Bei einer anderen Ausführungsform der Erfindung wird vorgesehen, dass die Baueinheit eine Tragkonstruktion besitzt, welche den Antriebsmotor, die Antriebselemente und die Übertragungselemente aufnimmt und mit Einrichtungen zum Aufstellen auf einem Boden versehen ist.In another embodiment of the invention it is provided that the assembly has a support structure which receives the drive motor, the drive elements and the transmission elements and is provided with means for placing on a floor.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass die Tragkonstruktion mit Führungen versehen ist, die die Webschäfte führen. Bei dieser Ausgestaltung ist die gesamte Fachbildungseinrichtung einschließlich der Webschäfte eine von der Webmaschine getrennt herstellbare Baueinheit, die getrennt von der Webmaschine zu dem Aufstellungsort gebracht und dort aufgebaut und montiert werden kann.In a further embodiment of the invention it is provided that the support structure is provided with guides that guide the heddle shafts. In this embodiment, the entire shedding device including the heald frames is a separate from the loom producible unit that can be brought separately from the loom to the site and built and assembled there.
Um die gesamte Fachbildungseinrichtung vollständig unabhängig von dem Rest der Webmaschine machen zu können, wird gemäß einer Ausführungsform der Erfindung eine als Tragkonstruktion ausgebildete Baueinheit vorgesehen, die Antriebselemente für Webschäfte enthält und die Führungen für die Webschäfte aufweist.In order to make the entire shedding device completely independent of the rest of the loom, according to one embodiment of the invention, designed as a support structure unit is provided which contains drive elements for heddle shafts and having the guides for the heald frames.
Um einen Antrieb zu schaffen, der möglichst unabhängig von den konstruktiven Gegebenheiten der Webmaschine ist, wird in Ausgestaltung der Erfindung vorgesehen, dass die Antriebswelle mittels eines eigenen Antriebsmotors angetrieben ist, dessen Motorachse parallel zur Antriebswelle verläuft und der zwischen der Antriebswelle und dem Hebelsystem in einem Bereich angeordnet ist, der von Verbindungsstangen überbrückt ist, die die Antriebselemente mit dem Hebelsystem verbinden.To create a drive that is as independent as possible from the structural conditions of the weaving machine is provided in an embodiment of the invention that the drive shaft is driven by its own drive motor whose motor axis is parallel to the drive shaft and between the drive shaft and the lever system in a Area is bridged, which is bridged by connecting rods that connect the drive elements with the lever system.
Da ein von dem Hauptantriebsmotor unabhängiger Antriebsmotor für den Antrieb der Webschäfte eingesetzt wird, besteht schon von vornherein eine konstruktive Freiheit. Da dieser Antriebsmotor zwischen der Antriebswelle der Antriebselemente und dem Hebelsystem angeordnet wird, ist er an einer bisher ungenutzten Stelle angeordnet, so dass durch ihn kein zusätzlicher Bauraum verbraucht wird. Der Antriebsmotor vergrößert den Bauraum nicht, der für den gesamten Antrieb benötigt wird. Die Anordnung des Antriebsmotors beeinträchtigt somit die Konstruktion der Webmaschine nicht. Diese Baueinheit lässt sich unabhängig von der Webmaschine herstellen und einer Funktionsprüfung unterziehen. Die Baueinheit kann selbstverständlich für den Transport und für die spätere Montage an oder in einer Webmaschine wieder zerlegt und an der Webmaschine erneut zusammengesetzt werden.Since an independent of the main drive motor drive motor for driving the heald frames is used, there is a constructive freedom from the outset. Since this drive motor is arranged between the drive shaft of the drive elements and the lever system, it is arranged at a previously unused point, so that no additional space is consumed by him. The drive motor does not increase the space required for the entire drive. The arrangement of the drive motor thus does not affect the construction of the loom. This unit can be independently of the Weaving machine and subject to a functional test. The assembly can of course be disassembled for transport and for subsequent assembly on or in a weaving machine and reassembled on the loom.
In Ausgestaltung der Erfindung wird vorgesehen, dass die Verbindungsstangen im Wesentlichen horizontal verlaufen und oberhalb oder unterhalb des Antriebsmotors angeordnet sind. In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass die Antriebswelle, die Antriebselemente, die Verbindungsstangen, das Hebelsystem und der Antriebsmotor in einem als Tragkonstruktion gestalteten Gehäuse angeordnet sind. Vorzugsweise wird dabei vorgesehen, dass das Gehäuse wenigstens zwei Teile aufweist, wobei an einem das Hebelsystem aufnehmenden Teil ein Teil angebracht ist, das den Antriebsmotor enthält. Diese beiden Teile des Gehäuses können nach einer Funktionsprüfung wieder getrennt und erst an einer Webmaschine wieder zusammengefügt werden.In an embodiment of the invention it is provided that the connecting rods extend substantially horizontally and are arranged above or below the drive motor. In a further embodiment of the invention it is provided that the drive shaft, the drive elements, the connecting rods, the lever system and the drive motor are arranged in a housing designed as a support structure. Preferably, it is provided that the housing has at least two parts, wherein on a part receiving the lever system, a part is attached, which contains the drive motor. These two parts of the housing can be separated again after a functional test and reassembled on a loom.
Vorteilhafterweise wird weiter vorgesehen, dass die Teile zu einem geschlossenen Gehäuse zusammenfügbar sind, dass zur Aufnahme eines gemeinsamten Ölbades dient. Bei dieser Ausführungsform wird vorteilhafterweise weiter vorgesehen, das der Antriebsmotor mit einem vorzugsweise zylindrischen Motorgehäuse versehen ist, das dichtend in das Teil eingesetzt ist. Damit wird verhindert, dass aus diesem Gehäuseteil Öl austritt oder Staub in das Gehäuse eintritt. Der insgesamt in das Gehäuse integrierte Antriebsmotor wird vorzugsweise mittels einer Ölkühlung gekühlt, da er weitestgehend nicht mit der Umgebungsluft in Kontakt ist. Für das Kühlen wird vorzugsweise das Öl des Ölbades verwendet.Advantageously, it is further provided that the parts are joined together to form a closed housing that serves to receive a common oil bath. In this embodiment, it is advantageously further provided that the drive motor is provided with a preferably cylindrical motor housing, which is sealingly inserted into the part. This prevents oil escaping from this housing part or dust entering the housing. The total integrated in the housing drive motor is preferably cooled by means of oil cooling, since he is largely not in contact with the ambient air. For cooling, the oil of the oil bath is preferably used.
