Definitions

  • the invention is in the field of spinning technology and relates to a method the preamble of the first claim.
  • the method according to the invention serves for attaching a yarn that is in a spinning machine or in a spinning station Spinning machine is formed from a staple fiber material, for example after a Can change, after a bobbin change, after a yarn break or after a other spinning disorder.
  • the method can also be used for piecing means for the restart of a spinning process.
  • the invention further relates to one for the Implementation of the method equipped spinning station according to the Preamble of the corresponding independent claim.
  • Spinning machines for spinning staple fiber materials usually have one large number of spinning stations, with one in each spinning station Longitudinal fiber a yarn is spun.
  • the longitudinal fiber structure is the first refined, that is, the amount of fibers per unit length is reduced by warping. Then the refined fiber structure becomes a yarn by twisting spun which yarn is then drawn off and wound up.
  • the longitudinal fiber structure is stretched, for example, by means of a drafting system or with the help an opening roller.
  • twine formation are various methods known: e.g. Ring spiders, pot spiders, bell spiders, Friction spinning, rotor end spinning, air spinning etc.
  • Attachments should be the same with regard to strength and fiber mass per unit length differ as little as possible from the other areas of the yarn produced. They should be as little as possible visible or otherwise detectable and they should the continued use of the yarn, starting with the continuation of the Affect the spinning process as little as possible.
  • the yarn end region is known from publication DE-4240653-A1 to roughen, or fiber ends from the dense fiber structure of the yarn to loosen and spread from the yarn, causing the intermingling with the new fed fibers improved and the tear strength of the attachment point is increased.
  • US-5802831 is according to the publications US-5809764 and US-5934058 (both Murata) still refined, in that the tapered Initial area of the longitudinal fiber structure before stretching by tearing off one small piece is shortened, and in that in a draft that is between Drafting device and swirl distribution point is used, the fiber mass of this Initial area is also specifically reduced.
  • the attachment point is usually compared to the remaining yarn up to 200% increased fiber mass for piecing sufficient tear resistance is given and the attachment points are up to 200 mm can be long, subsequently detected with a yarn cleaner and subsequently created splices replaced. Obviously, this is a very complex process.
  • the object of the invention is now a method for preparation or piecing to show the method with which attachment points can be produced, which both to meet higher demands in terms of strength and fiber mass assets than is the case for attachment points manufactured according to known methods. Furthermore, it is the object of the invention to create a spinning station which is suitable for the Implementation of the method according to the invention is equipped.
  • the method according to the invention is based on the knowledge that usually a if the spinning process is interrupted by tearing one Longitudinal fiber structure produced initial area has no significant taper and / or that such an initial area is not suitable even for stretching Creation of a satisfactory location is sufficient. According to the invention So the process does not become a process created by tearing and thereby if necessary, the tapered initial area is subject to normal distortion, but it is controlled by the delay in the refinement step an initial area with an increasing fiber mass is specifically formed.
  • the piecing phase advantageously entrains the longitudinal fiber structure in the refinement so controlled on the run of the refined fiber structure from the refinement agreed that the delay gradually decreases and thereby the expiring Fiber dressing has a gradually increasing amount of fibers over its length. It is essentially ensured by a run-in control that the delay gradually decreases in the refinement step (increasing inlet speed) until it assumes a value suitable for a normal spinning process.
  • the Outfeed speed of the refined fiber structure from the refinement can decrease during the period of time Delay may be constant (as for normal spinning process) or may be in adjustment a corresponding increase in the yarn formation speed for a problem-free Spinning on your part will be gradually increased.
  • the movement of the yarn end area through the swirl issuing point is so timed on the movement of the initial area of the fiber structure delivered from the refinement that the two tapering areas overlapping each other as completely as possible through the Twist are moved and complement each other to form a fiber mass that as little as possible of the fiber mass during the normal spinning process created yarn differs.
  • Spinning station like known spinning stations, has a refinement agent, a swirl imparting agent and a yarn take-off means.
  • inlet-side parts of the Refining agent independent of the outgoing parts of the refining agent controllable for a piecing routine, which piecing routine essentially therein there is, the distortion that the longitudinal fiber structure experiences in the refining agent from gradually reduce an increased value to a normal value.
  • the parts of the refining agent on the outlet side and the means for pulling off the yarn can are operated at normal speeds during the piecing routine or also a piecing routine with gradually increasing speeds run through.
  • the spinning station equipped for carrying out the method according to the invention thus has its own controllable drive for the infeed side internally Parts of the refinement or a correspondingly controllable gear between this inlet-side parts of the refining agent and a central drive.
  • the other parts of the spinning station to be driven can be connected simply to central drives or also through internal spinning stations, if necessary controllable drives are driven.
  • the spinning station is also equipped in a manner known per se so that the free End of yarn positioned upstream of the twist distribution point and with the Recommissioning of the refining agent can be deducted in a timed manner can, and for the fact that the supplied longitudinal fiber structure before the resumption of the Spinning process in a precisely defined and advantageously precise reproducible type is separated or torn.
  • FIG. 1 shows very schematically a tapering, free end region 1 of a yarn 11 to be drawn off in the drawing-off direction A and a free beginning region 2 of a refined fiber structure 10 fed in the feed direction Z with a fiber mass which increases in accordance with the tapering of the yarn, the end region 1 of the yarn 11 and the initial area 2 of the fiber structure 11 overlap for a piecing process. Furthermore, the figure shows an attachment point 3 in the finished yarn resulting from the connection of the two areas 1 and 2.
  • the yarn end region 1 has a fiber mass which decreases towards the yarn end over a taper length L.1.
  • the fiber bandage initial region 2 is essentially adapted to the tapering of the end region of the yarn 11, the tapering being continuous or also more or less stepped, and has approximately the same length L.2.
  • the lengths L.1 and L.2 are, for example, approximately 80 mm.
  • the overlap of yarn end area 1 and fiber assembly start area 2 is advantageously such that the fiber mass in the attachment point 3 is slightly larger than in the normally spun yarn. With this increase in fiber mass, the somewhat reduced fiber adhesion can be compensated for in the attachment point 3. It has been shown that attachment points can be produced with the method according to the invention which have sufficient tear strength 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, there is no need to reckon with places of significantly reduced fiber mass and therefore with reduced tear strength neither in the attachment point nor in its immediate vicinity.
  • FIG 2 shows very schematically the control of the piecing routine according to the inventive method.
  • the spinning process is shown on the left, in which a longitudinal fiber structure 10 'is fed in, drawn into a refined fiber structure 10 and spun into a yarn 11.

  • Time t.1 marks an interruption in the spinning process (can change, Bobbin change, spinning disorder) and the period between the times t.3 to t.5 or t.6 the piecing routine.
  • There is a gap between the interruption and the piecing routine Interruption of the spinning process, in which the for the restart of the spinning process necessary measures are carried out, in particular the preparation of the free yarn end and its positioning upstream of the Twist imparting zone.
  • This interruption can vary depending on the reason for the interruption and vary in length according to machine equipment.
  • piecing routines as illustrated in FIG. 2, exist for example in that the refinement outlet 13 during the Spinning interruption (t.1, or t.2 to t.3) is not stopped at all. Another variant is that the yarn formation 14 (especially the yarn take-off) only with the Outlet 13 can be stopped at time t.2 or even later. Another variant is that the piecing routine related to yarn formation is shorter than that Time required to create the attachment point (t.6 before t.5).
  • a control unit must be provided to control the piecing routine. This is data to provide the length and profile of the tapering of the yarn end area or to transmit corresponding measurement data on-line from a mass sensor which Mass sensor detects the fiber mass of the yarn end area.
  • the control unit controls at least the speed of the refinement inlet for execution the piecing routine.

  • the refined fiber longitudinal structure 10 is from the outlet cylinders 32 through the Fiber feed channel 26 sucked against the entrance of the yarn channel 24.
  • Through the Compressed air supplied to nozzles 22 produces, in addition to the aforementioned suction, in the area of the twine channel entrance is a vortex flow that serves to impart twist. That through this twist distribution resulting yarn 11 is through the yarn channel 24 in Trigger direction Z (trigger means not shown) deducted.
