Definitions
- the invention relates to a flyless spinning method for directly spinning sliver and a device with a drafting system according to the preambles of the independent claims.
- Finer yarns are usually obtained by interposing a flyer, by means of which a sliver with an exemplary weight of 5 ktex band to a roving (roving) with a Luntenmay 200 - 1200 tex warped and wound on a spool, to then present this to a ring spinning machine. It is an object of the present invention to develop a method and a device according to the preambles of the independent claims such that fine to very fine yarns can be obtained without the use of a flyer.
- the essence of the invention is that in the first drafting a thin strip is obtained, which is then provided with a protective rotation and then warped in the second drafting with a high delay.
- one or more fiber ribbons in the first drafting system are warped to form a thin sliver, which lies below the usual band weight at the exit of a section.
- a thin sliver which lies below the usual band weight at the exit of a section.
- the resulting sliver is not provided here with an effective protective rotation, apart from the low protection rotation (in the range of one rotation per meter sliver), which is obtained by the rotating belt channel and the other hand, much slower rotating round storage can.
- such a thin sliver in the prior art is not presented directly to a second drafting system.
- the sliver produced by the first drafting system has a band weight of less than 2.5 ktex, and preferably less than 1.3 ktex. Particularly preferably, the band weight of the sliver produced by the first drafting system is below 0.8 ktex. Such bands can be realized by means of a route by one or more slivers can be fed to this first drafting system.
- a single strip fed to the drafting system may have a strip thickness of about 5 ktex, which is warped in the drafting system with a draft of 6 to obtain a sliver with a fineness below 1 ktex.
- a sliver having a fineness of 1 ktex would be obtained.
- the device according to the invention is characterized in that the means for generating the protective rotation are designed such that the number of rotations per meter of sliver produced is greater than five, advantageously even greater than ten.
- the method according to the invention makes it possible to choose the delivery speed of the sliver produced by the first drafting device greater than 250 m / min, since the protective rotation makes the sliver less sensitive.
- the second drafting system is part of a spinning station of a ring spinning machine, which is designed and operated so that a delay of more than 40, preferably more than 70 and preferably more than 100 has.
- the storage of the stretched in the first drafting sliver can be done in pitchers.
- the stretched sliver is wound on a spool, which is then the spinning machine - in particular a ring spinning machine - submitted.
- the coil is arranged to wind up the stretched sliver with horizontally oriented coil axis. It is advisable in this case to oscillate the coil back and forth in the horizontal direction in order, for example, to achieve a cross or parallel winding of the sliver on the winding body.
- the storage organ which is formed for example as a band channel.
- the coil-near end of the filing device oscillates back and forth along the bobbin.
- the end remote from the coil can be arranged in a stationary manner, wherein the deposition member is moved in the manner of a pendulum.
- the storage element during the pendulum movement additionally be set in rotation about its axis in order to obtain a protective rotation in aufweri- on the bobbin mecanical rotation.
- the coil can also be aligned or be with a vertical coil axis, wherein the coil for winding the distorted in the first drafting sliver in the vertical direction can be changed.
- the coil can be made according to an alternative tive embodiment be arranged stationary, while the storage organ oscillates along the vertical bobbin.
- At least one nozzle can be used at the outlet of the first drafting system, which is designed, for example, as a pneumatically actuated compression nozzle.
- the compression nozzle may be provided between the first drafting device and downstream Kander rollers.
- the compaction nozzle is provided downstream of said calender rolls.
- the mentioned compression nozzle has a passage for the sliver.
- at least one through-bore opens eccentrically into this passage, which preferably extends at an angle or obliquely to the passage.
- the sliver in the passage channel is given a rotation about its longitudinal axis, which causes the desired protective rotation of the sliver.
- the device for generating a protective rotation can comprise a rotation tube which rotates about its longitudinal axis, either alternately in left and right rotation or only in one direction of rotation.
- the means for generating the protective rotation comprise a band channel, as is known, for example, in principle for depositing sliver in sliver cans.
- a band channel as is known, for example, in principle for depositing sliver in sliver cans.
- Such a belt channel is usually arranged in a turntable and has a curved space curve to store sliver in loops.
- the inlet and the outlet of the band channel is arranged on a common straight line in a preferred embodiment, which is used only for generating the protective rotation.
- the band channel is preferably rotated in this horizontal coil position around this straight line, which thus defines an axis of rotation, whereby the desired protective rotation is obtained.
- the band channel inlet and band channel outlet are preferably offset from one another.
- Figure 1 is a schematic representation of the production of
- Figure 2 is a schematic side view of the mechanics of a route
- FIG. 3 shows a drafting system with an oscillating horizontal cross-wound bobbin
- FIG. 4 shows a drafting arrangement with a horizontal parallel winding reel and an oscillating belt channel
- Figure 5 is a drafting with a vertical cross-wound bobbin, and 6a, b, c different means for achieving a protective rotation of the sliver at the exit of the drafting system according to the figures 2 to 4.
- FIG. 1 schematically shows a sequence of spinning machines.
- the hopper 105 of a card 100 is filled, for example, with cotton, and the card 100 produces from the cotton material in a known manner by carding the cotton a sliver FB.
- This sliver FB can be stored in a can 110 and then delivered to a downstream section 1 (as shown in FIG. 1), or the sliver FB 'is fed directly to the route 1.
- the line 1 produces from one or more slivers FB (shown is the case of only one sliver) a sliver FB 'which is wound on a spool 70 according to the embodiment of FIG. 1 (see also the following figures).
- a ring spinning machine 200 Downstream of the track 1 is a ring spinning machine 200 with a plurality of Riemchenstrecktechniken 204 (only one is shown), which in each case a coil 70 with sliver FB 'is supplied.
- the ring spinning machine 200 produces from this sliver FB 'a yarn G, which is also wound on a spool 290. According to the invention, no flyer is provided between the track 1 and the ring spinning machine 200.
- a route 1 is shown in more detail in Figure 2 in a schematic side view.
- a route 1 is shown in more detail in Figure 2 in a schematic side view.
- a sliver FB which is presented by an upstream carding or combing machine directly or under clipboard in a pot (see Figure 1).
- a funnel 12 is arranged, which compresses the slivers FB.
- other compressors may be used.
- the now compressed sliver FB ' which consists of the plurality of individual slivers FB, guided in a drafting system 4, which forms the core of the route 1.
- the drafting device 4 has three drafting elements or pairs of rollers, between which the actual distortion takes place. These are the input roller pair 5a, 5b, the middle pair of rollers 6a, 6b and the output or supply roller pair 7a, 7b, which rotate in this order each increased peripheral speed.
- the sliver FB ' which is laid out like a nonwoven in the drafting system and clamped along the clamping lines of the respective pairs of rollers, is warped in accordance with the ratio of the circumferential speeds.
- the pair of input rollers 5a, 5b and the middle pair of rollers 6a, 6b form the so-called pre-draft field VF, the middle pair of rollers 6a, 6b and the delivery roller pair 7a, 7b, the so-called main drafting field HF.
- a pressure bar 20 is also arranged, which deflects the fiber sliver FB 'and thus provides better guidance of the fibers, in particular the fibers not clamped between the two roller pairs 6a, 6b and 7a, 7b (so-called floating fibers).
- the warped sliver FB ' is summarized by means of a Umlenkoberwalze 9 and a belt forming device 10 and a Kalanderwalzencru 13, 14 and a curved band channel 16 which is arranged in a rotating with the angular velocity ⁇ turntable 17, at a speed v L in one Can 18 stored. The tape storage is thus accomplished by the belt channel 16 and the rotating pot.
- the sliver FB 'at the exit of the drafting system 4 has a band weight of less than 2.5 ktex.
- the tape weight is even less than 1.3 ktex, and preferably less than 0.8 ktex.
- the aim of this low band weight at the exit of the first drafting system 4 is, together with a high draft of more than 30, preferably more than 70 and preferably more than 100, in the second drafting unit 204 of the ring spinning machine 200 (see Figure 1) a yarn on the ring spinning machine 200, which ranges from a yarn count of below 100 tex down to 10 tex or even less.
- Such Garnföen are not yet known in flyerlosen process and are realized with the inventive design of the presented method or the presented device. Dispensing with the elaborate flyer saves space, time and costs.
- the sliver FB 'after leaving the first drafting system 4 is provided with an effective protective rotation to give it a higher strength, without thereby the defaulting ability in the second drafting system is significantly affected.
- this protective rotation which in the apparatus according to the invention is more than five rotations per meter of sliver, is realized by a band channel 26 rotating about a vertical axis 21 (see arrow f1), its inlet 26a and outlet 26a centric lie on this axis 21.
- the coil 70 reciprocates in the direction of its axis 71 (see arrow f3).
- the corresponding coil drives are not shown here for the sake of simplicity. Single drives or multiple drives can be used. Control via a central computer of the route 100 is recommended.
- the band deposition is realized by the band channel 26 and the winding device 75.
- a winding device 85 is shown with a stationary coil 80, which is set in rotation about its longitudinal axis 81 (see arrow f4) by a schematically indicated drive device 82.
- the coil-side end 36b of a spatially curved band channel 36 is frictionally engaged by an endless flat belt 88, which is wound around two horizontally spaced cylinders 87, 89 rotatable about their vertical longitudinal axes.
- the cylinder 87 is driven in such a way by a reversing motor 86 (see arrow f5) that the belt 88 oscillates back and forth (see arrow f6) while the outlet 36b of the belt channel 36 moves from one end of the reel to the other and back that the sliver FB 'is wound onto the spool 80.
- the spool-distal inlet 36a of the band channel 36 is substantially stationary, so that the band channel 36 moves in the manner of a slow pendulum. In the illustrated embodiment, a parallel winding is achieved on the coil 80 in this case. Any guide means to guide the band channel 36 exactly at this pendulum motion, are not shown for simplicity.
- the belt channel 36 is additionally rotated about its own longitudinal axis by the two-sided frictional engagement on the part of the belt (see arrow f7), whereby the desired protective rotation is achieved in the fiber belt FB '.
- a winding device 95 is provided with a vertically arranged coil 90 with the thus vertically aligned coil axis 91 at the output of the track 1. Again, the spool 90 travels up and down in the direction of the vertical axis 91 (see arrow f8) in order to wind up the sliver FB 'over the entire package height.
- a band channel 46 which is immediately downstream of the calender rolls 13, 14, also serves here to issue a protective rotation in the sliver FB '.
- the outlet 46b of the band channel 46 is eccentrically arranged so that the band channel 46 can rotate around the coil 90 to wind up the sliver FB '(see arrow f8).
- FIGS. 6a and 6b, 6c two possibilities are shown in order to impart protective rotation to the sliver FB '-as a alternative or in addition to a sliver channel 16, 26, 36 or 46.
- a rotary tube 56 is shown, which is set in rotation about its longitudinal axis according to arrow f10.
- the sliver FB' at the exit of the rotary tube 56 from which it is pulled off here by means of rollers 13a, 14a, receives the desired protective rotation before it is placed in a jug or wound on a spool.
- FIGS. 6b, 6c show an obliquely-cut top view or a sectional side view of a pneumatically actuated compression nozzle 66, which has a central through-passage 67 for the fiber band FB '.
- two through holes 68 running obliquely to the fiber-belt transport direction open eccentrically, into which compressed air is introduced (see arrows f11). This can on the one hand for threading of the sliver FB 'into the nozzle 66, on the other hand, for twisting the sliver FB' in the nozzle 66 (see arrows f8).
- the compression nozzle 66 may be upstream or downstream of the calender rolls 13, 14. For example, it can replace the band-forming device 10 or the band channel 26 shown in FIG.
- the inventive method makes it possible to set the delivery speed v L (see Figure 2) of the first drafting system 4 to more than 250 m / min, since the protective rotation of more than five turns per meter - advantageously more than ten turns per meter - the From the first drafting 4 produced sliver FB 'is sufficiently fixed.
- the invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims are possible.
- a ring spinning machine instead of a ring spinning machine, other spinning machines can be used, for example air or friction spinning machines.
- the false-twisting which is generated solely by the rotation of the curved band channel (in the range of one turn per meter), is thereby amplified.
- the speed ratio (revolutions per unit time) of the turntable 17 together with the belt channel 16 to the can 18 10 1, preferably 4: 1, preferably 2: 1 or even more effective - even below.
- this ratio is about 20: 1. It is advisable to put the can 18 in faster rotation to reduce the speed ratio in order to obtain the desired protective rotation.
- the invention can be used for routes in which the first drafting system can be regulated or unregulated.
