Definitions

  • the invention relates to a double-folding drafting system, as used for example in spinning knitting processes or other spinning processes.
  • Folding drafting systems are used to stretch fibers of a sliver into a fine ribbon prior to spinning. This stretching of the sliver is also referred to as delay.
  • Drafting systems that are currently in use are, for example, four-roller drafting systems which have two roller groups which are perpendicular to one another. A third pair of rollers carries straps which fold the fiber material emerging from the second pair of rollers and, in this state, feed a fourth pair of rollers from which the fiber material is warped to final fineness.
  • Such a drafting system is known, for example, from WO-A 2013/041220.
  • a double-folding drafting system comprising five pairs of rollers, wherein a first, a second, a fourth and a fifth pair of rollers have substantially the same orientation of the respective axes of the rollers and a third pair of rollers positioned between the second and fourth pair of rollers has an axial direction perpendicular to the axial direction of the others Aligned roller pairs,
  • a strap is guided around each roller of the third pair of rollers and at least one of the respective roller associated turning rail and - is guided around each roller of the fourth pair of rollers, a turning rail before and a turning rail behind the respective roller a strap.
  • the folding drafting device according to the invention is suitable for increasing the quality of textile fabrics which are produced in spinning knitting machines.
  • one roller of a pair of rollers is preferably driven in each case.
  • the second roller of the roller pair is pressed against the driven roller of the roller pair and therefore runs with.
  • straps are guided not only around the rollers of the third and fourth roller pair and the turning rails associated with the respective rollers, but also around each roller of the first roller pair and at least one turning rail assigned to the respective roller.
  • the straps are preferably made of polyurethane or silicone rubber.
  • the arrangement of the roller pairs four delay zones are formed.
  • two adjacent pairs of rollers form a delay zone, wherein a first delay zone between the first and the second pair of rollers has a delay which is comparable to the delay of a roving, a second delay zone between the second and the third pair of rollers and a third delay zone between the the third and the fourth pair of rollers have tension distortions and in a fourth draft zone between the fourth and the fifth pair of rollers, a main delay is realized.
  • the second and third zones of distortion simultaneously also constitute folding zones.
  • the sliver is folded a first time in the second drafting zone and a second time in the third drafting zone. Due to this double folding reduces the width of the sliver to a fraction of the original width. This has the advantage that a maximum possible uniformity of the width of the sliver 10 can be achieved even at high distortion in the range of 150 to 400 times.
  • the revolving rolls of the first, second and fourth roll pairs lie on a first pressure arm and a second
  • the 15 pressure arm carries the follower roller of the fifth pair of rollers.
  • the first pressure arm is preferably arranged in a hanging manner, especially when using the folding drafting system in a spinning-knitting machine.
  • the first pressure arm for example, be pneumatically resilient, in order in this way a sufficiently high contact pressure of the follower rollers on the driven rollers of the
  • the follower roller of the third pair of rollers is connected via a lever arm with a torsion shaft, wherein the torsional 30 generates the necessary Anpressmoment.
  • the torsion wave is preferably pneumatically loaded. This structure allows a slight change of the rollers of the third pair of rollers encircling straps, since the straps can strip off or roll on the rollers without further assembly effort.
  • the straps of the fourth pair of rollers have a different thickness, wherein the driving roller of the fourth pair of rollers circumferential straps has a greater thickness than the revolving roller of the fourth pair of rollers encircling straps.
  • the thickness of the revolving roller of the fourth pair of rollers revolving belt is preferably chosen as small as possible. At currently used straps in drafting the minimum thickness is usually 0.3 to 0.7 mm. However, the thickness is also dependent on the material from which the straps are made.
  • the belt surrounding the driving roller of the fourth pair of rollers has a thickness which corresponds to the thickness of straps conventionally used in drafting arrangements and which is usually greater than 1 mm.
  • a recess pointing in the direction of travel is formed in the surface facing the fiber flow.
  • the recess is formed centrally in the circumferential direction of the driving roller of the fourth pair of rollers.
  • the depression mimics the character of a so-called draft-drafting system, which stabilizes the drafting process, in particular with warping of more than 200 times.
  • the depression is preferably designed in the form of a rectangular channel, wherein a suitable channel, for example, has a width in the range of 5 to 10 mm, for example of 5 mm, and a depth in the range of 0, 1 to 0.25, depending on the fiber slivers used mm, for example of 0.25 mm.
  • the driven rollers of the second, third and fourth pair of rollers are coupled to a common transmission, wherein the transmission is associated with a motor or a drive train.
  • the driven rollers of the first and the fifth pair of rollers are each driven by a separate motor or drive train.
  • the drive of the driven rollers of the first and the fifth roller pair by a separate motor or drive train is particularly advantageous due to the different rotational speeds of the rollers in order to obtain the desired delay.
  • the rollers of the fifth pair of rollers must rotate at a multiple of the speed of the preceding rollers.
  • the folding drafting system according to the invention is particularly suitable for use in spinning knitting machines.
  • the spinning-knitting machine can be constructed as known from the prior art.
  • the folding drafting systems are combined into groups, which can also be referred to as drafting group groups.
  • the drafting system groups have drives which act either on the driven rollers of only one drafting system, on the driven rollers of several drafting systems or on the driven rollers of all drafting systems of a drafting group. If the driven rollers of a plurality of drafting units are driven by a drive, it is advantageous to drive in each case the driven rollers of corresponding pairs of rollers, for example in each case the driven rollers of the first pair of rollers, by a drive.
  • the drive of a plurality of driven rollers of respective pairs of rollers of the double folding drafting systems to comprise two groups, which are connected to one another by toothed belts, wherein one gear stage couples both groups.
  • the drive of the fifth roller pair comprises a reluctance drive and a servo drive. It is possible to provide each driven roller of the fifth pair of rollers with its own drive or all driven rollers of a section. Furthermore, it is possible and particularly preferred to provide all driven rollers of the fifth pairs of rollers of all drafting systems of the spinning knitting machine with a drive, in which case the drive torque is transmitted via suitable belts and gears.
  • first drive the driving roller of the fifth pair of rollers with the servo drive when the spinning machine starts up whereby the reverse drive can run or be switched on during acceleration and switch off the servo drive after reaching the production speed in that the drive of the driving roller of the fifth pair of rollers takes place via the reluctance drive and first the servo drive is engaged during the shutdown of the spinning machine, the drive of the driving roller of the fifth pair of rollers being taken over by the servo drive as the production speed is reduced, and the reluctance drive is switched off. Due to the smooth running of the reluctance drive can be achieved in this way a particularly uniform stretching of the fiber material. Since the slow access However, assuming or decreasing the speed of the spinning machine during startup or shutdown is not suitable to accelerate or decelerate the reluctance motor accordingly, is used for starting and stopping the servo motor.
