Description

Die Erfindung betrifft eine Antriebsanordnung für eine Webmaschine gemäss dem Oberbegriff des Anspruches 1 und Webmaschine mit Antriebsanordnung.The invention relates to a drive arrangement for a Loom according to the preamble of claim 1 and Loom with drive arrangement.

Es sind Webmaschinen mit einem Antrieb bekannt geworden, die eine Fachbildevorrichtung, einen Motor, der mit der Fachbildevorrichtung antriebsverbunden ist, einen Drehwinkelgeber, der mit dem Antrieb gekoppelt ist und eine Steuereinrichtung umfasst, die mit dem Drehwinkelgeber signalübertragend verbunden ist, um den Motor in Abhängigkeit der Drehzahl der Webmaschine zu steuern. Als Fachbildevorrichtung kann eine Schaftmaschine oder Jaquardvorrichtung vorgesehen werden.Weaving machines with a drive have become known which is a shedding device, a motor which with the Shed forming device is drive-connected, one Angle of rotation encoder, which is coupled to the drive and comprises a control device which with the Rotary encoder is connected to transmit the signal Motor depending on the speed of the loom Taxes. As a shedding device, a Dobby or jacquard device can be provided.

Im Betrieb treten bei einer Webmaschine periodische Drehzahlschwankungen auf, die von verschiedenen massebehafteten oszillierenden Maschinenteilen verursacht werden. Als Beispiel wird auf den Webladenantrieb verwiesen, welcher die Lade mit Webblatt samt ihren auf der Steuerkurve laufenden Getriebeteilen periodisch beschleunigen und verzögern muss. Hierzu addiert sich noch die zum Anschlagen des Schussfadens erforderliche Kraft, die bei verschiedenen Gewebearten beträchtlich ist. Daraus resultiert eine unstabile Drehzahl des Hauptantriebes der Webmaschine. Wird eine Fachbildevorrichtung mittels einem mit dem Hauptantrieb verbundenen Drehwinkelgeber synchron zur Webmaschine angetrieben, so ist ein erheblicher Energieaufwand erforderlich, um mit der Fachbildevorrichtung den Drehzahlschwankungen der Webmaschine zu folgen. Dies ist ein Nachteil.Periodic operation occurs with a weaving machine Speed fluctuations on that of different mass oscillating machine parts caused become. As an example, the web store drive referenced which the drawer with reed along with their the control curve running gear parts periodically accelerate and decelerate. This adds up still the one required to strike the weft Force that is considerable with different types of tissue is. This results in an unstable speed of the Main drive of the weaving machine. Will one Shed forming device by means of a with the main drive connected rotary encoder synchronous to the weaving machine driven, so is a considerable amount of energy required to use the shedding device Speed fluctuations of the weaving machine to follow. This is a disadvantage.

Die in Fig. 1 schematisch dargestellte Anordnung umfasst eine Webmaschine 1 mit einem Antriebsmotor 2 als Hauptmotor, eine Schaftmaschine 3 mit einem Antriebsmotor 4 als Nebenmotor und eine Steuereinrichtung 5. Dem Haupt- bzw. Nebenmotor ist jeweils ein Getrieb 6 bzw. 7 zugeordnet. Mit der Hauptwelle der Webmaschine 1 ist ein Drehwinkelgeber 8 verbunden. Mit der Hauptwelle der Schaftmaschine 3 ist ein Drehwinkelgeber 9 verbunden. Die beiden Drehwinkelgeber 8, 9 sind über Signalleitungen 10, 11 mit der Steuereinrichtung 5 verbunden. Die Steuereinrichtung 5 ist über die Leitung 12 mit dem Antriebsmotor 4 der Schaftmaschine 3 verbunden. Im Betrieb wird die Webmaschine 1 und die Schaftmaschine 3 jeweils von einem Antriebsmotor 2 bzw. 4 angetrieben, wobei zwischen den Drehwinkeln an der Hauptwelle der Webmaschine und der Schaftmaschine eine Differenz vorhanden ist. Diese Differenz beträgt im Normalfall einige Grad und entspricht einer für den Webbetrieb zulässigen Drehwinkeltoleranz.The arrangement shown schematically in FIG. 1 comprises a loom 1 with a drive motor 2 as Main motor, a dobby 3 with a drive motor 4 as a secondary engine and a control device 5. The main or A secondary engine is a gear 6 or 7 assigned. With the main shaft of the loom 1 is a Angle of rotation encoder 8 connected. With the main shaft of the A dobby 9 is connected to a dobby 3. The two rotary encoder 8, 9 are via signal lines 10, 11 connected to the control device 5. The Control device 5 is connected via line 12 to the Drive motor 4 of the dobby 3 connected. in the The weaving machine 1 and the dobby 3 are operated each driven by a drive motor 2 or 4, being between the angles of rotation on the main shaft of the Loom and dobby make a difference is available. This difference is usually a few degrees and corresponds to one for web operation permissible angle of rotation tolerance.

Der Antriebsmotor 4 der Schaftmaschine 3 wird von der Steuereinrichtung 5 angesteuert. Das dem Drehwinkel der Webmaschine 1 bzw. der Schaftmaschine 3 entsprechende Signal wird über die Leitung 10 bzw. 11 jeweils an ein Differenzierglied 14 angelegt und in ein der Drehzahl entsprechendes Signal umgewandelt, das den durch die Belastungen der Webmaschine verursachten Schwankungen folgt, d.h. einen welligen Charakter aufweist. Das Drehzahlsignal der Webmaschine wird in einer elektronischen Schaltung 15 in das die Welligkeit aufweisende Signal und in ein Mittelwertsignal zerlegt. The drive motor 4 of the dobby 3 is the Control device 5 controlled. That is the angle of rotation of the Weaving machine 1 or the dobby 3 corresponding Signal is on via line 10 or 11 respectively Differentiator 14 created and in a speed corresponding signal converted by the Loads on the weaving machine caused fluctuations follows, i.e. has a wavy character. The Speed signal of the weaving machine is in one electronic circuit 15 in which the ripple having signal and broken down into an average signal.

In der Einheit 16 werden die beiden Signale unter Einbezug eines Faktors k summiert. Der Faktor k wird in der Einheit 17 aus einem Wertebereich bestimmt, dessen Endwerte eine harte Regelung bzw. eine weiche Regelung festlegen. Bei der harten Regelung folgt der Antriebsmotor 4 der Schaftmaschine 3 dem Antriebsmotor 2 der Webmaschine 1 sehr genau, wie dies in der Fig. 3 durch die ausgezogenen Linie dargestellt ist. Bei der weichen Regelung folgt der Antriebsmotor 4 der Schaftmaschine 3 dem Mittelwert und ignoriert die Welligkeit ganz oder teilweise, so dass die Winkelposition der Schaftmaschine gegenüber der Synchronlaufposition geringfügig vor- oder nacheilen kann, wie dies in Fig. 3 durch die gestrichelte Linie dargestellt ist. Aufgrund dieser Regelstrategie werden einerseits beim Start die Webmaschine und Schaftmaschine im wesentlichen synchron betrieben und andererseits die Schaftmaschine während des Webbetriebes mit einer vorbestimmten Drehzahlschwankung betrieben, die innerhalb der Drehzahltoleranz der Webmaschine liegt.In the unit 16, the two signals are below Inclusion of a factor k summed.
