Abstract

Die Erfindung bezieht sich auf eine Antriebsvorrichtung für Abreisswalzen (23) an einer Kämmaschine mit einem Differentialgetriebe (21), dessen eine Eingangswelle mit einem der Eingangswelle eine gleichförmige Drehbewegung erteilenden Antrieb und dessen andere Eingangswelle mit einer eine zusätzliche Drehbewegung erteilenden Steuervorrichtung verbunden ist, mit einem am Gestell gelagerten Exzenter (8), der über eine Zugstange (10) mit einer dem Exzenter eine ungleichförmige Drehbewegung konstanter Antriebsdrehzahl erteilenden und gegenüber dem Exzenterdrehpunkt (B) versetzt gelagerten Kurbel (A,E) verbunden ist, wobei der Exzenter (8) eine an einem Umfangspunkt (J) über einen drehbar am Gestell gelagerten Stützhebel (14) gelenkig abgestützte Schwinge (11) trägt, welche zur Übertragung einer ihr vom Exzenter erteilten Bewegung über eine Koppel (16) mit einem Steuerhebel (17) der genannten anderen Eingangswelle (20) für die zusätzliche Drehbewegung verbunden ist. Mit der bekannten Anordnung war eine Grenze erreicht, wobei die Erhöhung der Kammspielzahlen nicht ohne Probleme möglich war. Auf der Basis der bekannten Ausführung zur Erhöhung der Kammspielzahlen wird deshalb eine spezielle Ausführung vorgeschlagen, wobei das Verhältnis zwischen dem Abstand des Anlenkpunktes (D) der Zugstange (10) am Exzenter (8) zu dessen Drehpunkt (B) zum Abstand zwischen der Mitte (C) der Schwinge (11) und dem Drehpunkt (B) des Exzenters (8) grösser als 3,5 gewählt ist.

Figure 00000001
The invention relates to a drive device for tear-off rollers (23) on a combing machine with a differential gear (21), the one input shaft of which is connected to a drive which gives a uniform rotary movement to the input shaft and the other input shaft of which is connected to a control device which gives an additional rotary movement, to a eccentric (8) mounted on the frame, which is connected via a pull rod (10) to a crank (A, E) which provides the eccentric with a non-uniform rotational movement of constant drive speed and is offset with respect to the eccentric pivot (B), the eccentric (8) being a at a circumferential point (J) carries a rocker arm (11) which is articulated by a support lever (14) which is rotatably mounted on the frame and which, in order to transmit a movement imparted by the eccentric, via a coupling (16) to a control lever (17) of the other input shaft ( 20) is connected for the additional rotary movement. A limit was reached with the known arrangement, and the increase in the number of combs was not possible without problems. On the basis of the known design for increasing the number of combs, a special design is therefore proposed, the ratio between the distance of the articulation point (D) of the pull rod (10) on the eccentric (8) to its pivot point (B) to the distance between the center ( C) the rocker (11) and the pivot point (B) of the eccentric (8) is selected to be greater than 3.5.
