Definitions

  • the invention relates to a combing machine with at least one combing head, which contains a continuously rotatable circular comb roller, a reciprocating pliers unit and at least one tear-off cylinder rotatable with a pilgrim step movement.
  • the round comb roller is continuously rotated by a drive motor.
  • the tear-off cylinder In each comb play, ie usually during each revolution of the circular comb roller, the tear-off cylinder must first be rotated backwards by a certain angle and then rotated forwards by another, larger angle.
  • this movement of the tear-off cylinder is derived from the rotation of the circular comb roller via a mechanical gear.
  • Such a transmission is very complicated and therefore expensive.
  • it contains relatively large masses that can be moved back and forth, which have a disadvantageous effect at higher comb play rates (revolutions of the circular comb roller), for example 350 to 400 per minute.
  • a device for driving the tear-off cylinders in which the intermittent drive movement of the tear-off cylinders takes place via a planetary gear differential in connection with an articulated pentagon with corresponding coupling links.
  • This drive is relatively complex and large flywheels have to be moved.
  • a drive device for the tear-off cylinder in which the drive is removed from a central gear via spur gear and coupling members.
  • the central gear is driven by a drive motor.
  • the drive of the tear-off cylinders represents an additional load on the main transmission, in particular with regard to the required dynamic acceleration of correspondingly large flywheels.
  • the object of the invention is to design the drive for the tear-off cylinder in the combing machine specified at the outset in such a way that the required movements of the tear-off cylinder can be produced with large masses which can be moved back and forth without expensive gear.
  • the object is achieved in that at least one electric motor is arranged in the combing machine according to the invention for rotating the tear-off cylinder with the vocational step movement.
  • the electric motor for example a brushless DC motor or an asynchronous motor, can be fed by a control device with drive pulses which are synchronized with the rotation of the circular comb roller, so that the motor first rotates backwards and then forwards during each comb play, preferably via a reduction gear . It is also possible to arrange a separate electric motor for the reverse and the forward rotation of the tear-off cylinder, each motor being connected to the tear-off cylinder via a coupling.
  • the combing head shown schematically in FIG. 1 has a circular comb roller 1, which is rotatable continuously by a drive motor (not shown) and which carries a circular comb segment 2, and a pliers assembly consisting of lower pliers 3 and upper pliers 4.
  • the lower jaw 3 is articulated at its front end to front supports 5 which can be pivoted about the axis of the circular comb roller 1 and is articulated at its rear end to tong arms 6 which are seated on a tong shaft 7 which can be pivoted back and forth.
  • the upper tongs 4 can be pivoted about an axis 8 with respect to the lower tongs 3.
  • the combing head also has two tear-off cylinders 9 and 10, on each of which a tear-off pressure roller 11 or 12 rests, and a pair of draw-off rollers 13.
  • a cotton wool W to be combed is fed from a cotton roll 14, which rests on two rotatable winding rollers 15 and 16, to an intermittently rotatable feed cylinder 17, which is mounted in the lower tongs 3.
  • the forceps unit 3, 4 In a retracted position (not shown) of the forceps unit 3, 4, the forceps unit 3, 4 is closed and holds a front end portion of the cotton wool W protruding from the forceps unit in the form of a fiber beard.
  • the fiber beard is combed out by the circular comb segment 2 on the rotating circular comb roller 1. Subsequently the pliers unit 3, 4 is moved into the advanced, open position shown.
  • the tear-off cylinders 9 and 10 have meanwhile been rotated backwards by a predetermined angle in order to allow the rear end section of the previously combed sliver F to emerge from the clamping point of the tear-off cylinder 9 with the tear-off pressure roller 11 to the rear (towards the pliers assembly).
  • the combed fiber from the round comb segment 2 lies on this end section and is pulled together with this back into the nip of the tear-off cylinder 9 with the tear-off pressure roller 11 when the tear-off cylinders 9 and 10 are then rotated forward.
  • the tear-off cylinders 9 and 10 are rotated forward by a second predetermined angle, which is greater than the first predetermined angle, for example approximately twice as large, and they tear off the fiber beard from the cotton wool lying in the pliers unit 3, 4. Normally, the fiber beard is pulled through a fixed comb, which, however, has not been shown in the drawing in order not to impair the clarity.
  • the tear-off cylinders 9 and 10 must therefore first be rotated backwards by a predetermined angle in each comb play and then rotated forward by another, larger predetermined angle. This movement is called the pilgrim step movement.
  • at least one electric motor 18, for example a brushless DC motor or an asynchronous motor is provided for rotating the tear-off cylinders 9 and 10 with the described mit step movement.
  • the motor 18 is connected to the tear-off cylinders 9 and 10 via a reduction gear.
  • this contains a gearwheel 19 on the shaft of the motor 18 which is coupled to a second gearwheel 21 via a toothed belt 20.
  • the gears 22 and 23 mesh with a pinion 24, which is seated on the shaft of the gear 21.
  • An electronic program control device 25 supplies the electric motor 18 with electrical drive pulses via an amplifier 26, so that the electric motor 18 rotates the tear-off cylinders 9 and 10 through the required angles during each comb play.
  • the drive pulses are synchronized with the rotation of the round comb roller 1.
  • the control device 25 is supplied with output signals from a speed sensor or position sensor 27 which scans markings on an element (not shown) carried on the shaft of the circular comb roller 1.
  • the control device 25 can expediently contain a controller which adjusts the output drive pulses in such a way that the tear-off cylinders 9 and 10 are each rotated through the required predetermined angles.
  • this controller is supplied with output signals from a speed sensor or position sensor 28, which scans markings on an element (not shown) carried on the shaft of the motor 18.
  • the control device 25 and the amplifier 26 are fed by a power supply device 29.
  • a combing machine usually contains several combing heads arranged in a row of the type described above.
  • FIG. 3 shows, similar to FIG. 2, a schematic partial plan view of the tear-off cylinder 9 and 10 of several combing heads of a combing machine.
  • an electric motor 18 ' is arranged, which rotates the tear-off cylinders 9 and 10 via the gear 19, 20, 21, 22, 23, 24 backwards.
  • a clutch 32 is additionally arranged in the transmission between the gear wheels 21 and 24.
  • a second electric motor 18 ′′ is arranged for the forward rotation of the tear-off cylinders 9 and 10.
  • the clutch 32 is again arranged.
  • the control device 25 leads the electric motors 18 'and 18 ⁇ drive pulses to and / or actuates the clutches 32 in order to rotate the tear-off cylinders 9 and 10 backwards and then forwards through the required angles during each comb play.
  • freewheels could also be used, in particular unlockable freewheels, so that the motor 18 ⁇ is not rotated when the motor 18 'rotates the tear-off cylinders 9 and 10 in reverse, and vice versa.
  • the reversible electric motor 18 (FIGS. 1, 2) drives only the tear-off cylinders 9 via the gear 19, 20, 21, 22, 24 - without the gearwheel 23 on the shaft 31 - the tear-off cylinders 10 then become one second reversible electric motor (not shown) driven, which is arranged at the other end of the shafts 30 and 31 and is coupled to the shaft 31 via a reduction gear (similar to the gear 19, 20, 21, 23, 24).
  • the electric motor 18 and the second electric motor, not shown, are fed by the control device 25 with the same, synchronous drive pulses.
