Definitions

  • the invention relates to a feed comb arrangement for a combing machine comprising an intermittently driven feed roller pair arranged upstream of the feed comb arrangement in the transport direction of the fiber fleece to be combed, and a take-off arrangement arranged downstream of the feed comb arrangement, in particular in the form of take-off rollers.
  • the food comb arrangement is formed by a flat food comb, which is equipped with a plurality of needles, the function of which is to synchronously transport the nonwoven fabric to be combed in the transport direction to the combing roller and to the tongs arrangement in accordance with the cycle of the combing games.
  • Another task of the food comb is to compress and retain the fibers outside the transport phase when the take-off rollers pull the combed fibers out of the nonwoven fabric. Accordingly, fibers attached to the comb are detached from the fibers to be extracted.
  • the movement sequence within a comb play is such that the feed rollers transport the nonwoven fabric over a certain distance in the direction of the combing cylinder and the take-off rollers. This make-up usually takes place at the moment when the combed fibers are pulled out of the nonwoven fabric held back by the comb. The comb is closed at this moment and the needles of the comb penetrate the nonwoven fabric. After the end of the feed, ie the transport movement through the feed rollers, the feed comb lifts out of the nonwoven fabric and moves back the distance that corresponds to the transport path through feed rollers.
  • Conventional food combs are realized in such a way that the needles in the form of pin strips are introduced into a base plate, each pin strip comprising a plurality of needles arranged next to one another.
  • the conventional food combs designed in this way have a considerable disadvantage in that, in addition to their transport and holding function, they also act as a combing element and cleaning element with respect to the nonwoven fabric, so that ever larger parts of burdock and straw parts accumulate on the needles of the food comb. These accumulations grow and are then drawn off in a compressed form, and because of their size they are often transported under the downstream fixed comb and accordingly remain as an impurity in the combed nonwoven.
  • Another significant mechanical disadvantage of known combs is that they have to go through four movement phases in different directions within a comb play. These movement phases include an approximately circular-arc movement to emerge from the nonwoven fabric, a backward linear movement to initiate a new feed phase, a further circular movement to pierce the nonwoven fabric and then again a linear movement to carry out the transport. Such jerky movements at about 200 combs per minute result in a combing machine of the type in question being associated with considerable unrest.
  • the object of the invention is to create a food comb arrangement which avoids the disadvantages of conventional food combs, in particular the accumulation of contaminants, and enables reliable transport and holding performance with a high level of smoothness.
  • the feed comb arrangement comprises a plurality of needle bars rotating on a closed path, the orbit being designed such that the needles of the pinstripes engage in the nonwoven fabric during part of the circulation route and the nonwoven fabric is synchronized with the comb play sequence due to an intermittent Hold the drive in a first phase and transport it in a second phase.
  • the comb arrangement according to the invention which is designed in the manner of a comb head, comprises a housing, curved tracks being formed on the inside of the lateral housing cheeks. Two inner curved tracks are used to transport the needle bars, whereas two outer tracks can be used to give the needle bars, which are preferably provided with one-sided cranks, the desired angular position of the needles.
  • Such an arrangement is known to the person skilled in the art as a continuously driven device from so-called drafting systems (cf. DE-OS 25 48 315), the drive of the needle bars in previously known drafting systems either via a chain or via a linear drive (cf. EP-PS 0 184 671) can take place.
  • drafting systems cf. DE-OS 25 48 315
  • EP-PS 0 184 671 a linear drive
  • the main difference between a feed comb arrangement according to the invention and previously known drafting arrangements lies in addition to the different purpose and location, especially in that the comb arrangement according to the invention is driven intermittently.
  • drafting devices serve to prevent the fiber sliver from being torn off, which is stretched between two pairs of rollers, which for this purpose is continuously operated at different speeds, e.g. with a speed ratio of 1: 8. Accordingly, known drafting systems do not have to perform a transport function and, alternately, do not have to perform a holding function.
  • the needle bars which are used in the feed comb arrangement according to the invention are designed in such a way that on one side of the needle bar there is the already mentioned crank which specifies the angular position of the pinstrip.
  • Bearings are provided on the two end sides of each needle bar, which engage in the guide curves for the orbital movement.
  • the alternating distance between the needle bars is also set by the bearings of the needle bar.
  • the needles or needle-like stamped parts of the needle bar are arranged on it in a rotationally fixed manner and extend over the central region in accordance with the width of the nonwoven fabric.
  • the needle bars are driven, for example, by sprockets, which ensure that the needle bars perform a certain distance in the direction of the take-off rollers in the interval of the comb play, as determined by the feed rollers as the transport path.
  • the drive mechanism is preferably implemented in such a way that a drive disk is driven synchronously with the feeder rollers, preferably derived directly from the intermittent movement.
  • FIG. 1 shows a food comb 1 according to the prior art.
  • a combing machine (not shown in detail), a nonwoven fabric 2 to be combed is fed in the transport direction (arrow 3) through a pair of feed rollers 4 to a tongs arrangement 5, with a protruding part of the fiber beard 2 being combed by a circular comb 6 when the tongs arrangement 5 is closed and the combed part is pulled off again via a pair of take-off rollers 7.
  • the food comb 1 shown in FIG. 1 executes a movement cycle which, according to FIG. 1a, comprises a linear transport movement in order to carry out the feeding.
  • the feed comb 1 is then lifted upward in an approximately circular arc-shaped movement in order to pierce the nonwoven fabric, as shown in FIG. 1b.
  • a conventional food comb 1 comprises a flat, plate-like support body 9 and a plurality of rows of needles 10.
  • FIGS. 3 and 4 a comb arrangement according to the invention is shown in FIGS. 3 and 4.
  • This comprises two side cheeks 11, on the inside of which guide tracks 12 are provided for the circumferential movement of needle bars 13 which are laterally mounted in the guide tracks 12 and which are provided with a multiplicity of needles or sawtooth punched parts 14, only a few of these are indicated in FIG. 4.
  • Not shown in the drawing are crank projections of the needle bars 13, which run along a separate guideway and ensure that the needles or the tips of the sawtooth punched parts 14 have a desired orientation in every phase of movement with respect to the central longitudinal axis of each needle bar 13.
  • the design in this regard is not described further here because it is known per se from drafting systems.
  • the guideways 12 in the side cheeks 11 are designed such that the needles or sawtooth tips 14 engage along a lower section in the nonwoven fabric 2 and accordingly can transport this in a movement phase and hold it in a subsequent holding phase, after which they emerge from the nonwoven fabric and be moved upwards.
  • a rotating cleaning brush 18 is arranged, which combs out contamination from the needles or sawtooth tips 14 passing by, a suction hood 19, which is connected to a suction channel 20, ensures that the combed out contamination in the direction of the arrow 21 are suctioned off.
