Definitions

  • the present invention relates to a combing machine according to the preamble of claim 1.
  • Soldering is a very important quality feature.
  • the good soldering of the fleece (sliver) is characterized by a parallel and stretched position of the fibers, combined with an even distribution of fibers in the longitudinal and transverse directions.
  • a good soldering requires a trouble-free placement of the beginning of the subsequent fiber structure (that is, the beard) on the trailing end of the ridge.
  • the object of the present invention is to increase the number of combs while at the same time maintaining a good quality of the soldering.
  • a pliers head 3 with a clamping bracket 8 is pivotally attached to a pliers shaft 2, to which a circular comb 4 with a needle segment 5 is assigned.
  • the pliers head 3 interacts with tear-off rollers 6.
  • the one to be combed Cotton wool 7 is fed to the pliers head 3 continuously from a winding roller, not shown, which rests on a continuously driven pair of shafts, also not shown.
  • the preceding end of the batting 7, the so-called fiber beard 10, is connected to the ridge 11 held between the tear-off rollers 6 - subsequently to its mit-like backward movement (called soldering), conveyed and separated from the trailing batting 7.
  • the needle segment 5 is cleaned from the combs combed out of the fiber beard 10 by a brush roller 12 rotating in opposite directions and rotating with a larger circumferential speed.
  • the pliers head 3 has lower pliers 13 articulated on the pliers shaft 2 and upper pliers 14 pivotably mounted thereon.
  • the lower jaw 13 essentially consists of a lower jaw arm 15 and a lower jaw plate 16 fastened thereon.
  • the upper jaw 14 is pivotally mounted on upper pivot pin 17 of the lower jaw arm 15 with an upper jaw plate 21 (knife).
  • a feed roller 18 for the cotton 7 is stored, which converts the continuous cotton feed into a discontinuous.
  • the hollow body-like pliers plate 16 there is an air chamber 26, which is continuously connected to a compressed air source, not shown, for example by means of an elastically stretchable hose 27 even during the lifting movements.
  • a clamping surface of the lower pliers plate 16, which cooperates with the upper pliers plate 21, opens out essentially over its width Slot nozzle 28 (Fig. 5a) or a series of slot openings or bores (Fig. 5b, c) through which the blown air can escape from the air chamber 26 in the direction towards the tear-off rollers 6 below the fiber beard 10.
  • the upper pliers plate 21 bears against the slot nozzle opening and closes it.
  • the upper pliers 14 basically consist of an upper pliers arm 20 articulated on the pivot pin 17 and the upper pliers plate 21 attached to it, as well as a lever 9 firmly connected to the upper pliers arm 20. Furthermore, an adjustable insertion comb 19 is mounted on the upper pliers 14, which combs those fibers of the fiber beard 10 who do not have the length of the tear-off distance (ecartement) from being drawn into the tear-off rollers 6.
  • the upper pliers plate 21 can be pivoted in the rhythm of movement of the pliers head 3 against the lower pliers plate 16 or away from it, and in such a way that the pliers head 3 is closed in the rear (shown in FIG.
  • the tear-off rollers 6 are made up of two pairs of tear-off rollers 6 ', 6'' formed, each of which has a lower, driven 23 and an upper non-driven tear roller 24.
  • the tear-off rollers 6 can also be formed by only one pair of tear-off rollers 6 ′′.
  • Their periodic forward and backward control causes (as already mentioned) a total removal of the ridge 11 in the direction of the arrow 25 and a connection with the combed fiber beard 10 fed by the pliers head 3.
  • the sector angle of the needle segment 5 and the radius of the circular comb 4 are dimensioned such that all the needles of the needle segment 5 comb through the fiber beard 10 once in the region of the rear (shown in FIG. 1) end position of the pliers head 3.
  • the combing machine is driven by a motor 31, which drives a clock shaft 33 via a reduction gear 32. With each revolution of the clock shaft 33, the machine executes a backlash.
  • a crank pin 34 rotating with the clock shaft 33 is operatively connected by a crank rod 35 to a pivot pin 36 on a lever 36 ', which is firmly connected to the pliers shaft 2 and whose pivoting movement during one revolution of the clock shaft 33 pulls the pliers head 3 out of the rear one the front end position and pivoted back.
  • the circular comb 4 and the lower tear-off rollers 23 are driven in a clock-synchronized manner by the clock shaft 33 and, via a mit step mechanism 37 known per se, so that their forward and reverse travel takes place during a comb play, as in the known combing machines.
  • the peripheral speed of the brush roller 12 is greater than that of the counter-rotating Round comb 4.
  • the pliers head 3 swivels around the pliers axis 2 from the rear end position (in which it comes very close to the circumferential circle of the circular comb 4) into the front end position and back, the preceding edge of the lower pliers plate 16 moving on an arc 41.
  • the preceding edge of the pliers plate 16 moves away from the circular comb 4 and approaches it again during the return.
  • the pliers head 3 closes before the needle segment 5 starts combing out the fiber beard 10 and only opens again when the needle segment 5 and the fiber beard 10 have separated from one another.
  • the fiber beard 10 is brought with its preceding end for soldering to the trailing end of the ridge 11.
  • the air outlet from the slot nozzle 28 (or a corresponding row of nozzle bores) is released when the pliers 3 are opened (FIG . 2 to 4).
  • the air stream emerging from the slot nozzle 28 acts on the underside of the fiber beard 10 and holds it stretched in front of the lower pliers 13 swinging onto the tear-off rollers 6.
  • the cross section, direction and strength of the air stream must be dimensioned such that during the outward movement during a comb play a defined position for the fiber beard 10 and correspondingly an exact impact and placement of the fiber beard tip on the trailing end of the comb 25 results.
  • a reducing valve can be provided between the compressed air source (not shown) and the air chamber 26, with which the pressure or the speed of the air emerging from the slot nozzle 28 can be optimally adjusted depending on the stiffness of the fiber beard and the working speed of the machine.
  • the direction of the blowing air can be directed against the underside of the fiber beard 10 at an acute angle instead of in the direction of movement in order to achieve a substantially planar orientation.
  • This variant can be useful when working with larger amounts of blown air and lower blown air pressure.
  • the support and stabilization of the fiber beard 10 takes place at the end of the preliminary stroke movement, that is, at the moment in which it comes into contact with the ridge 11 and the soldering process begins.
  • the speed of which is essentially sinusoidal the pliers head 3 is decelerated to a standstill, as a result of which the air resistance drops and the inertia throws the free end of the fiber beard 10 against the ridge 11.
  • a precisely determined position can therefore be achieved with comparatively low blowing air speeds and quantities the fiber beard 10 and a consistently high quality of the soldering are forced.
