Definitions

  • the present invention relates to a drafting system with a device for compressing drafted slivers in a spinning machine.
  • Drafting devices for spinning machines comprise at least two pairs of rollers between which a fiber structure is drawn due to the different speeds of the pairs of rollers.
  • the pair of rollers after which the drafted fiber structure leaves the drafting system and is fed to a spinning device is referred to as the pair of exit rollers.
  • the pair of output rollers consists of an output upper roller and an output lower roller, which form a nip through which the fiber strand is conveyed.
  • Devices for compressing the stretched fiber structure are arranged after the exit roller pair, mechanical as well as pneumatic compression devices are used.
  • the compacting device disclosed therein is of a pneumatic design and essentially consists of a suction shoe, a perforated transport means and a drive roller for the compacting device.
  • the fiber bundle leaving the pair of output rollers of the drafting system is placed on the perforated transport means and guided by it via the suction shoe to a pair of delivery rollers.
  • a disadvantage of the disclosed device is, in addition to an additionally required drive shaft for the perforated transport means and the pair of delivery rollers, that a long fiber bundling zone is provided, whereby the individual fibers of the drawn product The fiber structure can be moved over the suction shoe without being clamped. This can lead to a loss of the stretching of the fiber structure determined by the drafting system.
  • the DE 199 22 861 A1 discloses a method for compressing a drafted fiber structure in a compression zone following a pair of output rollers of a drafting system.
  • the fiber structure is transported through the compression zone by means of a perforated, vacuum-extracted conveyor belt. It is provided that the fiber strand has the same direction of movement as the transport means when it reaches the compression zone. Furthermore, care is taken to ensure that a sufficient quantity of the fibers in the fiber structure is still clamped by the pair of exit rollers during compression. This leads to the advantage that the front ends of the fibers of the fiber assembly to be compressed do not dip into the perforation of the conveyor belt and thereby lead to constipation.
  • the distance between the two clamping points is selected so that it is at most slightly larger, but preferably smaller than the average staple length of the fibers in the fiber structure. Densification takes place in the drafting field level by compressing the fiber structure in which the fibers are displaced transversely to their longitudinal axis. The hairiness of the fiber structure is hardly affected by this.
  • the object of the present invention is to further develop known devices and to create a compacting device that is simple in construction and can be used at individual spinning stations, which is characterized by a uniform reduction in the hairiness of the fiber structure.
  • Proposed is a drafting system for a spinning machine for drawing a fiber structure, with at least a first pair of rollers consisting of an upper roller and a lower roller, and with a second pair of rollers consisting of an output upper roller and an output lower roller, and with a fiber compression downstream of the output roller pair for compressing the drawn fiber structure .
  • the fiber compaction has a pneumatic compaction device with a fiber bundling zone and with a suction tube that is wrapped around by a screen element and that can be sucked out.
  • a first nip point is defined by the first pair of rollers and a second nip point by the second pair of rollers, and the first nip point and the second nip point form a drafting field plane through which the fiber strand runs in a running direction from the first nip point to the second nip point.
  • the upper exit roller Seen in the direction of travel of the fiber structure, has a curtain opposite the lower exit roller in the drafting field plane and a third nip is defined by the exit top roller and the screen element.
  • a nip length from the second nip point to the third nip point along a surface of the output top roller is less than an average staple length of the fiber structure to be drawn.
  • a suction pipe is arranged after the pair of output rollers. Which is at least partially wrapped by a screen element.
  • a fiber bundling zone is located between the second and the third nip, enclosed by the screening element and the elements forming the second nip. In this fiber bundling zone, the drawn fiber structure leaving the second clamping point is bundled.
  • the fiber bundle emerging from the pair of output rollers hits the screen element shortly before reaching the third nip point and is guided on it to the third nip point. In this way, the fiber structure is bundled by the influence of an air current.
  • the sieve element runs around the suction pipe, which has a suction opening in the area between the second and the third clamping point.
  • the ambient air sucked in through the suction opening means that individual fibers protruding from the fiber structure are moved to the suction opening and the fiber structure is thus bundled.
  • conventional pneumatic compaction in which the fiber structure is moved on a screen element transversely to its direction of travel and the fibers are thus pushed together, with fiber bundling only fiber parts or fiber ends protruding from the fiber structure are brought up to the fiber structure without the fiber structure being deflected from its direction of travel .
  • the fiber ends are guided to the fiber structure by a pneumatic suction flow and applied to the fiber structure in the third clamping point.
  • the suction tube and thus the screen element are advantageously brought as close as possible to the second clamping point.
  • a nip length is formed along a surface of the output top roller, which is smaller than an average fiber staple length of the fiber strand to be compressed.
  • the fiber bundle is transported in a defined manner from the second to the third clamping point.
  • the fiber bundling zone only the fiber parts protruding from the fiber structure are brought into the fiber strand.
  • the air flow ensures that fiber parts or fiber ends protruding from the fiber structure are guided to the fiber structure, with the fiber structure itself not being transported directly through the screen element, but instead passing through the fiber bundling zone held by the clamping points. This eliminates the so-called hairiness of the fiber structure and binds the hair into the fiber structure.
  • the constant clamping of at least one fiber end also prevents the fiber structure from losing or partially losing the stretching applied in the drafting system while passing through the fiber bundling zone.
  • the screen element is also driven by the output top roller through the third clamping point.
  • the frictional drive of the screen element creates a slight slip, so that the screen element has a lower speed than the output roller pair. This circumstance also contributes to the fact that bundling of the fiber assembly, or integration of protruding fiber ends in the fiber assembly, becomes possible.
  • the curtain of the upper exit roller compared to the lower exit roller, measured in the drafting zone is 2 mm to 15 mm, particularly preferably 5 mm to 12 mm.
  • the curtain of the upper exit roller opposite the lower exit roller enables the third nip to be located close to the second nip.
  • the ratio of the diameter of the top roller to the diameter of the bottom roller is 1.4 to 2.5.
  • the enlargement of the upper exit roller compared to the lower exit roller improves the spatial arrangement of the fiber bundling zone.
  • the upper exit roller preferably has a diameter of 34 mm to 60 mm and the lower exit roller has a diameter of 24 mm to 36 mm.
  • the selected diameters of the rollers lead to the creation of a fiber bundling zone that is not too large and avoid excessive deviations in the further course of the fiber structure after the compression device to a spinning device after the compression device has been attached to existing spinning machines. A further conversion of the spinning machine, for example by changing the arrangement of the drafting field level, to maintain the process conditions prevailing before the compaction device was attached is therefore not necessary.
  • the nip length from the second nip point to the third nip point along a surface of the output top roller is preferably 12 mm to 20 mm.
  • the protruding fiber parts are bundled into a fiber structure in such a way that they are securely integrated in the subsequent spinning process. As a result, other fiber parts are used for substance utilization in the yarn compared to an uncompacted fiber structure.
  • the short clamping length has the advantage that only the free fiber ends are moved and the fiber bundling forces only have to overcome the stiffness of the individual fibers.
  • the screen element is advantageously deflected after the third clamping point in such a way that a detachment point on a surface of the screen element at which the compacted fiber strand detaches from the screen element is less than 10 mm, preferably less than 5 mm, away from the third clamping point. It is also advantageous if the detachment point in the radial direction of the output top roller of the third nip is less than 4 mm away from a surface of the output top roller.
  • the shortest possible guidance of the fiber structure through the sieve element after the third clamping point results in further advantages for the geometric arrangement of the subsequent spinning device. This also minimizes the risk of the fiber structure shifting laterally on the sieve element and thus damage to the previously bundled fiber structure.
  • the upper exit roller preferably has a shorter axial length than the lower exit roller. This results in the advantage that tilting of the axes of the upper output roller and the lower output roller is largely avoided. Even with increasing wear of the linings of the output rollers, good running reliability and maintenance of the second and third nip point is achieved.
  • the compression device is advantageously arranged on a machine frame of the spinning machine or on the drafting system.
  • the attachment is preferably arranged on a pressure arm of the drafting system.
  • lifting the pressure arm which usually also carries the top rollers of the pairs of drafting rollers, not only is the entire drafting system opened, but the compacting device is also raised. This has advantages for the maintenance of the drafting systems.
  • a ring spinning machine is proposed with at least one drafting system for compressing a fiber structure in a spinning machine according to the above description.
  • FIG 1 shows a schematic representation of a longitudinal section of a spinning machine according to the prior art, in particular a ring spinning machine.
  • Individual components of the spinning machine are shown by way of example, namely a drafting system 2 and a spinning device 10.

  • the nip formed by the input roller pair 3 is not essential.
  • the fiber structure 1 entering the drafting system 2 is between the rollers of the roller pairs 3, 4 and 5 is clamped by the nip points of the pair of input rollers and K1 and K2 and stretched due to the different speeds of the pairs of rollers 3, 4 and 5.
  • the fiber structure 1 is transported through the drafting system 2 at the same time.
  • the pairs of rollers 3, 4 and 5 form a drafting field plane which is inclined towards a spinning device 10.
  • the drafted fiber structure 8 reaches a thread guide 9 and is carried on to the spinning device 10.
  • the course of the drafted fiber structure 8 from the drafting system 2 to the thread guide 9 has a significant impact on the operational reliability of the spinning device and the quality of the yarn to be produced with it.
  • the spinning device 10 consists essentially of a ring rail 14, which carries the spinning ring 12, and a spindle rail 15, on which the coil 13 is attached.
  • the fiber structure 8 arrives at the spool 13 via a rotor 11.
  • the spool 13 is set in rotation, with the result that the rotor 11 is also set in rotation by the fiber structure 8 on the ring 12. Due to the different rotational speeds of the bobbin 13 and the rotor 11, the fiber strand 8 is rotated and a yarn is thereby formed which is wound onto the bobbin 13 by moving the ring rail 14 up and down.
  • FIG 2 shows a schematic representation of a longitudinal section of an embodiment according to the invention of a compression device of the drafting system.
  • the apron roller pair 4 consisting of an upper roller 16 and a lower roller 17 forms a first nip K1.
  • the output roller pair 5, consisting of the output lower roller 7 and the output upper roller 6 forms a second nip K2.
  • the fiber strand 1 to be drafted is guided in the running direction 25 by the pairs of rollers 4 and 5 through the drafting system.

  • the upper exit roller 6 has a diameter D which is greater than the diameter E of the lower exit roller 7. Due to these specific geometric relationships between the upper exit roller 6 and the lower exit roller 7, ideal conditions for the formation of a fiber bundling zone 18 are created.

  • the suction tube 19 is wrapped around by a sieve element 21, which is designed as an endless belt and is guided over a deflection 22.

  • the suction opening 20 is preferably formed as a slit-shaped opening in the wall of the suction pipe 19.
  • the suction pipe 19 is connected to a vacuum source (not shown), which causes air to be sucked out of the fiber bundling zone 18 via the suction opening 20 and thus also through the screen element 21 sliding over the suction opening 20 . Due to the resulting air flow, the stretched Fiber structure used on the screen element 21, with individual fibers or fiber parts protruding from the drawn fiber structure being conveyed to the suction opening 20 and thus clinging to the drawn fiber structure.
