Definitions

  • the invention relates to a combing machine according to the preamble of patent claim 1.
  • a combing machine with a plurality of combing heads which comprises a nipper unit with a pivotally mounted upper nipper plate and a rotatable lower nipper plate and each having a rotatably mounted on a common shaft combing cylinder, wherein a movement of the upper nipper plate controlled by a rotational angular position of the combing cylinder by means of a control device and each combing cylinder is provided on its circumference with a combing segment and a tear-off segment, and wherein the Abreisssegment a rotatably mounted Abreisswalze is deliverable.
  • the device according to the WO 2010/012112 A1 has the disadvantage that the tearing off the rotatably mounted tear-off roller is delivered to each combing head at the same time the corresponding tear-off. This leads to increased friction on the outer circumference of the respective Abreisssegmentes and an associated braking effect, so that the common shaft undergoes an imbalance during operation.
  • the upper tong plate is mechanically connected to the common shaft and thus additionally influences the imbalance of the common shaft.
  • the common shaft is mechanically loaded so that act especially at a high number of combing very high torque peaks on the common shaft.
  • These mechanical loads, which act on the common shaft can be so high that the life of the common shaft is considerably reduced.

  • the combing out of the fiber batt with the combing segment commences according to region C following the region B.
  • these very high mechanical loads acting on the common shaft are shown as torque peaks of eight superimposed torque waveforms in the present example (1st KK * 8). Since the torque curve at each combing head is approximately equal, the torque peaks in the positive and negative directions multiply correspondingly at the same time of one revolution per combing game. Thus, eight superimposed torque curves (1st KK * 8) result in the maximum positive torque (100%) of a single combing head (1st KK), as in Fig. 3 now 8 times higher and thus has a maximum positive torque of 800% (see Fig. 4 ). Accordingly, a high number of combing heads in a combing machine results in a corresponding multiplication of the maximum torque peaks acting on the common shaft, thereby significantly reducing the life of the common shaft.

  • the resultant Fig. 4 is an envelope of the respective positive and negative torque peaks of the eight mutually offset Kämmzylin-the eight adjacent Kämmköpfen (1. KK to 8. KK).
  • the resultant has a significant reduction of the positive and negative torque peaks compared to the eight superimposed combing games on eight combing heads (1st KK * 8).
  • the torque curve 1KK * 8 has an absolute torque swing of 1900% (amount of about -1100% to about + 800%) while the resultant has an absolute torque swing of 30% (amount of about -135% to about -105%).
  • the common shaft is divided into at least two sections or more. These sections are connected via drive connections with the common shaft, so that a plurality of combing cylinders is rotatably mounted on each section. Accordingly, the combing cylinders are arranged to each other with an offset on the sections.
  • a drive connection gear or belt drives can be used as a drive connection gear or belt drives.
  • the plurality of combing cylinders are arranged on the subsections in each case without an offset to one another, wherein the adjacent subsections have an offset from each other by the drive connections from the common shaft to the subsections are arranged with the offset to each other.
  • the offset may be at an angle ⁇ of 15 ° or more to provide relief of the common shaft from mechanical stress.
  • a cam and a counter cam disc are provided on the common shaft for each combing head.
  • the countercurve disk can be used, since it mechanically compensates for the mechanical loads which act on the common shaft, counter to the rotational movement of the cams. In this alternative way, a compensation of the mechanical loads for the common shaft is thus possible.
