Definitions

  • the invention is in the field of spinning technology and relates to a method according to the preamble of the first claim.
  • the inventive method is used for preparing a yarn which is formed in a spinning machine or in a spinning unit of a spinning machine from a staple fiber material, for example after a can change, after a bobbin change, after a yarn breakage or after another spinning disturbance.
  • the method can also serve for piecing, that is, for the restart of a spinning process.
  • the invention further relates to a spinning station equipped for carrying out the method according to the invention according to the preamble of the corresponding independent patent claim.
  • Spinning machines for spinning staple fiber materials usually have a large number of spinning stations, wherein a yarn is spun in each spinning station from a fed longitudinal fiber structure.
  • the fiber longitudinal structure is first refined, that is, the amount of fiber per unit length is reduced by delay.
  • the refined fiber strand is spun by twisting into a yarn, which yarn is then peeled off and wound up.
  • the fiber longitudinal structure is stretched, for example, by means of a drafting device or dissolved by means of an opening roller.
  • various methods are known: e.g. Ring spinning, pot spinning, bell spinning, friction spinning, rotor spinning, air spinning etc.
  • the fibers of the fiber structure are swirled by the twist distribution with the fibers of the yarn end region and the initial region of the fiber structure is connected to the end region of the yarn in a kind of splice, whereby the spinning process is again normally operable.
  • US-5802831 is further refined according to the publications US-5809764 and US-5934058 (both Murata), in that the tapered initial region of the fiber longitudinal structure is shortened by stretching a small piece before stretching and in that in one Air draft, which is used between drafting and twist distribution point, the fiber mass of this initial area is additionally reduced specifically.
  • the object of the invention is now to show a method for setting or piecing, with which method Ansetzstellen can be produced, which are able to meet higher demands both in terms of strength and with respect to fiber mass, as is the case for Ansetzstellen prepared according to known methods. Furthermore, it is the object of the invention to provide a spinning station, which is equipped for carrying out the inventive method.
  • the method according to the invention is based on the finding that usually an initial region produced by disruption of the spinning process by tearing of a longitudinal fiber structure has no substantial taper and / or that such an initial region is not sufficient to produce a satisfactory piecing point even after stretching.
  • an initial region resulting from tearing and thereby, if necessary, tapering is not subjected to a normal distortion, but an initial region with an increasing fiber mass is formed in a targeted manner by appropriate control of the distortion in the refinement step.
  • the movement of the yarn end region through the twist distribution point is timed to match the movement of the initial region of the fiber structure delivered from the refinement, that the two tapered areas are moved as completely as possible overlapping each other by the twist distribution and complement each other to a pulp that deviates as little as possible from the fiber mass of the created during the normal spinning yarn.
  • a spinning station equipped for carrying out the method according to the invention has, like known spinning stations, a refining agent, a twisting agent and a yarn draw-off agent.
  • inlet parts of the refining agent are controllable independently of outgoing parts of the refining agent for a piecing routine, which piecing routine consists essentially of gradually reducing the delay which the fiber longitudinal formation undergoes in the refining medium from an increased value to a normal value.
  • the outgoing side portions of the refining means and the means for yarn withdrawal may be operated at normal speeds during the piecing routine or may also undergo a piecing routine at gradually increasing rates.
  • the spinning station equipped for carrying out the method according to the invention therefore has its own internally controllable drive for the inlet-side parts of the refining means or a correspondingly controllable transmission between these inlet-side parts of the refinement means and a central drive.
  • the other parts of the spinning unit to be driven can be driven by simple coupling to central drives or also by internally spinning, optionally controllable drives.
  • the spinning station is further equipped in a conventional manner for that the free yarn end can be positioned upstream of the twist distribution point and timed with the re-commissioning of the refining agent, and for the fact that the supplied fiber longitudinal structure before the resumption of the spinning process in a well-defined as possible and advantageously of exactly reproducible kind is separated or torn.
  • FIG. 1 very schematically shows a tapered, free end region 1 of a yarn 11 to be drawn off in draw-off direction A and a free starting region 2 of a refined fiber structure 10 fed in the feed direction Z with a fiber mass adapted to the rejuvenation of the yarn, the end region 1 of the yarn 11 and the initial region 2 of the fiber structure 11 overlap for a piecing process. Furthermore, the figure shows a result of the connection of the two areas 1 and 2 Ansetzstelle 3 in the finished yarn.
  • the yarn end region 1 has a fiber mass which decreases towards the yarn end over a taper length L.1.
  • the fiber composite starting region 2 is substantially adapted to the taper of the end region of the yarn 11, wherein the tapers may be continuous or more or less stepped, and has approximately the same length L.2.
  • the lengths L.1 and L.2 are for example about 80 mm.
  • the overlap of yarn end region 1 and fiber strand starting region 2 is advantageously such that the fiber mass in the application point 3 is slightly larger than in the normally spun yarn. With this increase in the fiber mass, the slightly reduced fiber adhesion can be made up in the piecing station 3. It can be seen that with the method according to the invention, piecing points can be produced which have sufficient tear resistance and which at no point have a fiber mass which is more than about 20% higher than the average fiber mass per unit length of the yarn. In particular, neither in the Ansetzstelle still be expected in the immediate vicinity with places a much reduced fiber mass and thus with reduced tensile strength.
  • FIG. 2 shows very schematically the control of the piecing routine according to the inventive method.
  • the spinning process is shown, in which a fiber longitudinal structure 10 'is fed, drawn into a refined fiber structure 10 and spun into a yarn 11.
  • the fibers thereby pass through a refinement inlet 12 (optionally combined with a pre-refinement), a refinement outlet 13 and the yarn formation 14 (twist distribution and yarn withdrawal).
  • the speeds G.1 (run-in speed), G.2 (run-off or delivery speed) and G.3 (yarn take-off speed) of the three stages are shown on a respective time axis and in particular their change in the case of an interruption of the spinning process and a subsequent piecing routine according to FIG Invention.
  • these velocities as shown in Figure 2 prior to time t.1, are constant or vary in a concerted manner.
  • the ratio of G.1 and G.2 essentially determines the delay of the refinement step, the ratio of G.2 and G.3 the spin delay.
  • the time t.1 marks an interruption of the spinning process (can change, bobbin change, spinning disturbance) and the period between the times t.3 to t.5 or t.6 the piecing routine.
  • Between interruption and Anspinnroutine is an interruption of the spinning process, in which the measures necessary for the restart of the spinning process are carried out, in particular the preparation of the free yarn end and its positioning upstream of the twist distribution point. This interruption may vary depending on the reason for the interruption and depending on the machine equipment.
  • piecing routines consist, for example, in the fact that the attenuation outlet 13 is not stopped at all during the spinning interruption (t.1 or t.2 to t.3). Another variant is that the yarn formation 14 (in particular the yarn withdrawal) are stopped only with the outlet 13 at time t.2 or even later. Another variant is that the piecing routine relating to yarn formation is shorter than the time required for the preparation of the piecing location (t.6 before t.5).
  • a control unit is provided. These are to provide data on the length and profile of the taper of the yarn end region or to transmit corresponding measurement data of a mass sensor on-line, which mass sensor detects the fiber mass of the yarn end region.
  • the control unit controls at least the speed of the refinement entry to perform the piecing routine.
  • FIG. 3 shows an exemplary embodiment of a spinning station for carrying out the method according to the invention.
  • This spinning station is equipped for a so-called air spinning process with refinement by stretching.
  • the spinning station has for twisting a nozzle block 21 with therein admitted nozzles 22, a spindle 23 with a yarn channel 24 and a feed block 25 with a fiber feed channel 26 and a directed against the entrance of the yarn channel 24 needle 27.
  • the spinning station on a drafting system 28 with, for example, three pairs of cylinders (inlet cylinder 29, central cylinder 30 with straps 31 and outlet cylinder 32).
  • the fiber longitudinal formation 10 'fed between the inlet cylinders 29 enters the refinement between the inlet cylinders 29, and is biased between inlet cylinders 29 and center cylinders 30 with a usually constant stretching ratio and between central cylinders 30 and Auslaufzylindern 32 subjected to a main delay with an optionally variable draw ratio.
  • the refined fiber elongate structure 10 is drawn from the discharge cylinders 32 through the fiber supply channel 26 against the entrance of the yarn channel 24.
  • Compressed air supplied by the nozzles 22 generates, in addition to the aforementioned suction effect in the region of the yarn channel entrance, a swirling flow which serves for the swirl distribution. That through this twist distribution resulting yarn 11 is withdrawn through the yarn channel 24 in the withdrawal direction Z (withdrawal means not shown).
  • the motor 33 is stopped while the outlet cylinders 32 continue to run for at least a limited period of time (t.1 to t.2, FIG. 2).
  • t.1 to t.2, FIG. 2 the supplied fiber longitudinal structure 10 'is torn between the straps 31 and the outlet cylinders 32 and the downstream piece is carried away from the drafting system by the outlet cylinders 32, so that it can be disposed of.
  • the upper part of the feed block 25 and the upper of the discharge cylinder 32 are lifted from its working position, such that the fiber feed channel 26 and the passage between the discharge cylinders 32 for positioning the Garn End Schemees 1 is accessible.
  • the yarn end portion 1 is retracted in such a equipped spinning station for the resumption of the spinning process into the main drafting area between center cylinders 30 and 31 and Auslaufzylindern 32 hanging freely around the lower of the discharge cylinder 32, where it is monitored by the yarn end sensor 37 ,
  • the yarn end portion 1 can be positioned for the resumption of the spinning process after an interruption also between the discharge cylinders 32 and the feed block 25 or between the feed block 25 and the nozzle block 21, wherein for the latter case between the two blocks 25 and 21, a corresponding gap must be provided, through which the yarn end portion 1 can be positioned and then easily removed.
  • These two variants are indicated by dash-dotted lines in FIG. 3 and the correspondingly positioned yarn end regions are denoted by 1 'and 1 ".
  • the yarn end sensor 37 is to be correspondingly positioned for the variants mentioned.
  • the piecing routine is controlled in a spinning station, as shown in FIG. 3, as follows: When the yarn end (1, 1 'or 1 ") is positioned and all relevant parts of the spinning station in FIG are repositioned to their working position, the control unit 34 is notified, for example by personnel or by a piecing robot, of the ready signal 35.
  • the control unit thereupon starts the finishing run, the twist pitch and the yarn take-off (possibly with a predetermined stagger) so that the yarn end begins to bear against the
  • the control unit receives the yarn end signal 36, which starts the actual piecing routine, according to a signal determined by the relative position of the yarn end sensor 37 and the beginning of the fiber longitudinal structure (FIG. relevant spinning station-own parameters) and by the L
  • the motor 33 is started and ramped up after a ramp adapted to the taper profile of the yarn end region.
  • the said ramp In order for the said ramp to be predetermined, it is necessary for prepared yarn end regions to have a reproducible and precisely known taper. If this is not the case, it is also possible to use an appropriately positioned mass sensor to measure the yarn end area on-line and to control the increase in the inlet speed based on the generated measurement signal.
  • the yarn end sensor 37 can also take over the function of the mass sensor.
  • control unit 34 is also provided with data relating to the starting profile of discharge cylinders 32 and yarn take-off and optionally measurement data from correspondingly arranged rotational speed sensors.
  • the twist distribution that is, in the present case, the speed of the air supplied from the nozzles 22 for the production of the Ansetzstelle changed over the normal spinning process, for example, be increased for a stronger Faserverwirbelung.
  • FIG. 4 shows a spinning station in which the twist distribution is again realized by a turbulent flow, as has already been described in connection with FIG.
  • the supplied fiber longitudinal structure 10 'but is not refined by stretching in a drafting but by a fiber separation.
  • the refining agent thus has a feed roll 40 and an opening roller 41 and may further comprise a suction roll 42 and a take-off roll 43.
  • the spinning station shown in FIG. 4 and in particular the refinement agent and its function are described in Swiss Patent Application No. 0753/00 (Obj. 2828).
  • the delay occurs between the feed roller 40 and the opening roller 41.
  • further rollers are used for the separation of dirt and the collection of isolated fibers to a fiber structure.
  • the feed roller 40 constitutes the refinement inlet and the further rollers (41, 42, 43) following the feed roller 40 complete the refinement outlet.
  • the feed roller 40 (motor 33) is stopped and the opening roller 41 and the optionally following rollers 42 and 43 as long continue to operate until they are substantially free of fibers. Then, the prepared yarn end 1 is positioned, for example, around the suction roll 42 (or between feed block 25 and suction roll 42, or between die block 21 and feed block 25) in which region the yarn end sensor 37 is located. After carrying out these measures enabling the resumption of the spinning process, all parts of the spinning station are taken up to the feed roller 40 and operated at speeds that are usual for a normal spinning process. Thus, the yarn end begins to move against the twist distribution point.
  • the feed roller is started after the yarn end signal and a suitably long delay and its speed is increased via a suitable ramp, as described in connection with FIG. 3 for the intake and center cylinders of the drafting system.
