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.
  • the piecing points to be made in the case of spinning breaks should differ as little as possible from the other areas of the yarn produced in terms of strength and fiber mass per unit length. They should be as little as possible visible or otherwise detectable and they should affect the further use of the yarn, starting with the continuation of the spinning process, as little as possible.
  • a fiber longitudinal structure is warped before the twist distribution in a drafting system, wherein the drafting system has an inlet-side pre-draft zone and an outlet-side main draft zone. After an interruption of the spinning process, the inlet of the fiber longitudinal structure in the drafting system and the pre-delay is stopped. The fact that the main delay is not stopped, the fiber longitudinal structure between the pre-draft zone and the main draft zone is torn, where it forms a free beginning.
  • the initial region of the longitudinal fiber structure which is believed to have a tapered shape as a result of the tearing off, is first subjected to the main distortion, it being assumed that the said taper is stretched accordingly, thereby providing an improved attachment point.
  • 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 collection of fiber longitudinal pattern in the refinement controlled so matched to the outlet of the refined fiber structure from the refinement that the delay gradually decreases and thereby the leaking fiber structure over its length gradually increasing fiber amount having. It is thus ensured essentially by an inlet control that the delay in the refinement step gradually decreases (increasing inlet velocity) until it assumes a suitable value for a normal spinning process.
  • the rate of emergence of the refined fiber aggregate from refinement may be constant during the time of decreasing warpage or may be gradually increased to accommodate a corresponding increase in yarn formation speed for easy piecing.
  • 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 supplied from the refinement, that the two tapered regions are moved as completely as possible overlapping each other by the twist distribution and complement each other to a fiber mass as little as possible differs from the pulp of the yarn produced during the normal spinning process.
  • 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 portions of the refining agent are controllable independently of outgoing portions of the refining agent for a piecing routine, which piecing routine is essentially to gradually reduce the warpage experienced by the longitudinal fiber formation in the refining agent from an increased value to a normal value.
  • the outlet side parts of the refining agent and the means for Garnabzug may be operated at normal speeds during the piecing routine, or may also undergo a piecing routine at gradually increasing speeds.
  • 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 shows very schematically a tapered, free end portion 1 of a withdrawn in the withdrawal direction A yarn 11 and a free beginning region 2 of a supplied in the feeding direction Z refined fiber structure 10 with a tuned to the taper of the yarn increasing fiber mass, the end portion 1 of the yarn 11 and the Start 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 in their immediate environment with a significantly reduced fiber mass and thus reduced tensile strength must be expected.
  • 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 speeds are as in the FIG. 2 shown before time t.1, 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 are, for example, that the refining spout 13 is not stopped during the spin 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 be provided with data about 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 inventive method.
  • This spinning station is equipped for a so-called air spinning process with refinement by stretching.
  • the spinning unit has a nozzle block 21 for the swirl distribution with nozzles 22 embedded therein, a spindle 23 with a yarn channel 24 and a feed block 25 with a fiber feed channel 26 and one directed against the entrance of the yarn channel 24 Needle 27 on.
  • 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 inlet of the drafting device 28, so for example, the inlet cylinder 29 and the central cylinder 30 with straps 31 are driven by a motor 33.
  • the motor 33 is controllable by a control unit 34.
  • the control unit 34 utilizes a ready signal 35 and a yarn end signal 36 of a yarn end sensor 37 for controlling the motor 33, as well as spinning unit-specific parameters and data relating to the tapering of the yarn end region.
  • the fiber longitudinal formation 10 'fed in the feed direction Z enters into the refinement between the inlet cylinders 29, and is subjected to a primary draft with a usually constant draw ratio and between central cylinders 30 and outlet cylinders 32 to a main draw with an optionally variable draw ratio between inlet cylinders 29 and center cylinders 30.
  • 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.
  • the yarn 11 produced by this twist distribution is withdrawn through the yarn channel 24 in withdrawal direction Z (removal means not shown).
  • 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 in the FIG. 3 indicated by dot-dash lines and the correspondingly positioned yarn end regions are denoted by 1 'and 1 ", and the yarn end sensor 37 is to be correspondingly positioned for the variants mentioned.
  • the piecing routine as used in the FIG. 2 is shown in a spinning station, as shown in the FIG. 3
  • the control unit 34 is notified, for example by personnel or by a piecing robot, of the ready signal 35.
  • the control unit starts thereupon, the refining spout, the twist pitch, and the yarn take-off (optionally with a predetermined stagger) so that the yarn end begins to move against the twist dispensing location
  • the control unit receives the yarn end signal 36, by which the actual piecing routine is started, after a deceleration determined by the relative position of the yarn end sensor 37 and the beginning of the fiber longitudinal formation (relevant spinning unit parameters) and the length of the prepared, tapered yarn end region, the motor 33 is started and after one Ramped 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 are also data with respect to the starting profile of discharge cylinders 32 and Garnabzug to provide and optionally measurement data of appropriately arranged speed sensors.

  • the drafting device 28 upstream of a twisting arrangement in a spinning station may also have only two or more than three pairs of cylinders, with a spinning-in interruption being an inlet-side part of the cylinder pairs is stopped before a downstream part of the cylinder pairs and wherein after the spinning interruption at least the inlet-side part of the cylinder pairs is raised to a predetermined or based on sensor signals ramp.
  • FIG. 4 shows a spinning station, in which the twist distribution is in turn realized by a turbulent flow, as already in connection with the FIG. 3 has been described.

  • the in the FIG. 4 Spinning point and in particular the refining agent and its function are described in the 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 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 increases its speed over a suitable ramp, as in connection with the FIG. 3 has been described for the inlet cylinder and center cylinder of the drafting system.
