  • the present invention relates to textile combing machines of the type in which detaching rollers are driven alternately in opposite directions of rotation and is particularly concerned with a drive for such rollers.
  • Detaching roller drives hitherto proposed conventionally comprise a differential gear which compounds a constant rotary motion with an oscillatory motion to provide the required gradually advancing forward and backward motion of the rollers.
  • the oscillatory motion is provided by an arrangement of articulated levers driven by an eccentric in the form of a rotary cam plate having a continuous cam groove in which is engaged a cam bowl drivingly connected to one of the levers, the arrangement being such that a complete revolution of the cam plate causes the articulated levers to impart a forward movement and then a backward movement to a planet wheel of a differential gear.
  • a drive for detaching rollers of a textile combing machine comprising a differential gear including a rotary motioncompounding element compounding a constant speed rotary motion of a first input drive to the gear with an oscillatory motion of a second input drive to the gear, said second input drive comprising a first pivotal element pivotally attached at one point thereof to an eccentrically located point on a rotary driving member arranged for rotation in one direction at constant speed and pivotally attached at a second point remote from said first point to a first point on a second pivotal element which is pivotally attached at a second point thereon remote from the "ice first point thereon to an eccentrically located point on the rotary motion-compounding element of the differential gear, the first pivotal element being pivotally attached at a third point thereon intermediate said first and second points thereon to a first point on a third pivotal element which is pivotally attached at a second point thereon remote the first point thereon to a stationary portion of the machine frame.

  • FIG. 2 is a rear sectional elevation of the drive shown in FIG. 1, taken on the line IIII in FIG. 1, and
  • FIG. 3 is a sectional side elevation of a detaching roller drive according to a second embodiment of the invention.
  • a drive to the detaching rollers of a textile combing machine is taken from an output shaft 12 of a differential gear comprising an annular sun wheel 13 mounted for free rotation about the axis of the comber cylinder shaft 14 and formed with a peripheral, gear annulus 15 having external gear teeth 16 and internal gear teeth 17, the former of which are arranged to drive a gear 18 fixed to the output shaft 12 of the differential and the latter of which are arranged to be drivably engaged by the external peripheral gear teeth 19 on a planet Wheel 20 mounted for free rotation on an eccentric bush 21 fixedly mounted on the comber cylinder shaft 14.

  • the doublearm lever 32 pivots in an anti-clockwise sense about its pivot point 37 on the uppermost end of the supporting lever 35, which in turn pivots about its lowermost end on the machine frame to permit the required upward translational displacement of the double-arm lever 32.
  • the link 33 which is attached to the lower end of the doublearm lever 32 turns in a clockwise sense and as a result of the raising of the double-arm lever 32 and the oppositely direction turning movements of the latter and the link 33, the planet wheel is caused to turn clockwise on its eccentric bush 21, the cranking of the lever 32 and the link 33 from their in-line positions combining with the translational raising movements of the double-arm lever 32 and link 33 to produce a rapid clockwise turning movement of the planet wheel 20.
  • the lever 32 and link 33 begin to straighten and they reach their in-line positions as the upper end of the double-arm lever 32 passes through the bottom dead center position, during which movement the planet wheel reaches the end of its excursion and dwells for a predetermined period there.

  • the cylinder shaft 38 is rotated at constant speed so as to impart a constant speed drive to the shaft 43 carrying the eccentric bush 58 rotatably supporting the planet wheel 57, as well as to impart a constant speed drive to the shaft 41 carrying the eccentric boss 44 supporting the eccentric ring 45.
  • the planet wheel 57 is given two motions, one being the constant speed angular displacement derived from the bush 58 and the other being an oscillatory motion about the bush 58 and derived from the eccentric drive to the ring 45, and the connection of the ring to the arm 55 on the planet wheel by the link 53.
