Definitions

  • the invention relates to a method for producing spinning cops according to the preamble of claim 1 and to a ring spinning machine for carrying out the method.
  • Ring spinning machines for producing spinning heads have long been known and described in detail in numerous patents.
  • Such textile machines each have a multiplicity of identical workstations on their longitudinal machine sides, which in turn each have different, stationary or vertically displaceably mounted working elements.
  • On each of the machine long sides for example, a gate for receiving supply bobbins, a drafting device for warping the provided by the supply bobbins original material and a stationary spindle bank for receiving rotatably mounted spinning spindles are provided.
  • a ring rail for receiving spinning rings and ring travelers, a bank for balloon constriction rings and a bank for thread guide available.
  • the vertically displaceably mounted usually designed as a machine-length benches components of the ring spinning machine are controlled by a corresponding drive mechanism 'according to a predetermined spinning program and ensure in conjunction with the rotatably mounted in the spindle spindle spindles that are made of the template material spinning cops.
  • the spin cops made on the workstations of such ring spinning machines, which contain relatively little yarn volume, are wound in a subsequent operation on the jobs of winding machines to large-volume cheeses.
  • the work stations of the winding machines are also equipped for this purpose with various bobbin handling or thread processing facilities.
  • the workstations of such winding machines have, for example, a winding device for the production of cheeses and a receiving device in which the spinning cop can be positioned to rewind functionally.
  • the workstations include, among other things, a yarn tension sensor, a yarn tensioner and an electronic yarn cleaner, all of which are connected to a bobbin control computer which also communicates with a central control unit of the winder via a machine bus or the like.
  • Fadenzugkraftsensoren as for example by the DE 41 29 803 A1 are known, in conjunction with thread tensioners ensure that the thread is wound during Umspulvorganges with a predetermined, constant as possible thread tension on the cheese.
  • Electronic yarn cleaners for example, in the EP 1 143 236 B1 ensure that during the winding process only perfect yarn is wound up on the cross-wound bobbin. That is, the withdrawn from the spinning cop thread runs on its way to a large volume cheese by the electronic
  • Yarn cleaner which continuously monitors the running thread for thread defects during the rewinding process and ensures that thread defects are immediately cleaned and replaced by almost yarn-like thread splices.
  • electronic yarn cleaners By means of such electronic yarn cleaners, however, not only yarn defects can be detected, but also the hairiness of a running yarn can be determined.
  • the winding speeds with which the work stations of winding machines work are limited to about 2000 m / min due to various physical conditions, in particular due to the thread tension forces occurring during the rewinding process.
  • the yarn tension starting from a relatively low value at the beginning of Kopsappel, increases sharply in the course of Kopsappel, wherein in the last third of the Kopsappel the yarn tensile forces if no effective countermeasures are taken, they increase to a multiple of the initial yarn tension, which greatly increases the risk of yarn breakage.
  • the thread tensioners are initially relatively strongly loaded for this purpose at the beginning of the cop travel of the spinning cop, and the contact pressure of the thread tensioners is successively reduced in the course of the cop trip according to the thread tension measured by the yarn tension sensors.
  • the thread tensioners are fully opened at a certain point of the cop trip and then no influence on the thread tension by the thread tensioner is given, methods have been developed to ensure that occurring during Umspulvorganges yarn tension even after the complete Opening the thread tensioner can be kept below a critical range.
  • Such a method or a device is for example in the CH-PS 669 177 described.
  • DE 10 2008 016 930 A1 discloses a ring spinning machine and a method for producing spinning cops whose arranged on a cop tube winding has a predetermined by the spinning program of a ring spinning machine position and size.
  • the present invention seeks to develop a method that makes it possible to produce on the jobs of ring spinning spinning frames, which are designed so that they have an optimal flow behavior during subsequent rewinding on the jobs of winding machines.
  • a ring spinning machine for carrying out the method according to the invention is the subject of claim 7.
  • the inventive method in which the position and size of the winding to be produced on the jobs of a ring spinning machine spinning cops is determined by the fact that when rewinding at least one Spinnkopses on a job of a winder evaluates the Abspul the spinning cop, the result of the Transmitted ring spinning machine and processed by the control of the ring spinning machine to optimize the position of the winding, in particular has the advantage that it is ensured in spinning cops made such that it is not a significant during the entire coil travel, even if constantly wound at high winding speed Increase in the thread tension comes.
  • spinning cops produced in this way can be continuously rewound on the work stations of the winding machines at a very high winding speed, without the risk of an increased occurrence of yarn breakages.
  • the yarn tension force sensor thereby establishes a constant increase in the yarn tension to be compensated by the yarn tensioner, whereby a limit value is exceeded for the end of the yarn despite a completely open yarn tensioner, which is evaluated by the control device of the winding machine as the beginning of a problem zone of the winding of the spinning cop ,
  • the yarn tension values determined during the rewinding process are processed such that the optimal position and size of the winding of the spinning cop is calculated by the control device, whereby the optimum position of the winding from yarn section to yarn section may vary and depends, for example, on the yarn material and / or yarn size.
  • the values determined by the controller of the winder are transmitted to the control device of the ring spinning machine and the spinning program of the ring spinning machine corrected so that the position of the windings of the newly produced spinning cops is optimized.
  • the yarn tension can, however, as a parameter for determining the optimum position of the winding of the newly produced on the work stations of ring spinning machines spinning cops, as described in claims 5 and 6, during the unwinding Considering the spinnopops adjusting hairiness of the yarn. Since the hairiness of the yarn when unwinding a Spinnkopses towards Kopsende towards clearly increases, can be detected by the control device of the winder as the beginning of a problem zone of the winding of the spinning cop in a relatively simple manner, the exceeding of a limit of Garnhaartechnik Formation can be avoided in subsequent to the ring spinning machine to be produced spinning cops by correcting the position of the winding of the spinning cops in their production on the ring spinning machine.
  • the data supplied via this interface, provided by the control device of the winder data are processed in the control device of the ring spinning machine and implemented to correct the spinning program. That is, the data introduced via the interface are used by the control device of the ring spinning machine for optimizing the position and size of the winding of newly produced spinning cops.
  • the ring spinning machine is directly connected to the winding machine via the interface.
  • control device of the ring spinning machine is connected directly to the control device of the winding machine, so that the values determined during the winding process are transmitted immediately to the control device of the ring spinning machine and directly from this during the production of the new spinning cops can be implemented so that they no longer have the identified during the unwinding problem zone.

  • a (not shown) automatically operating service unit preferably a cheese changer
  • Such winding machines 1 generally also have a logistics device in the form of a bobbin and tube transport system 6, in which, on transport plates 11, the spinning cops 3 or empty tubes circulate.
  • the sleeve transport system 6 are in Fig.1 only the Kopszu scent zone 24, the reversibly driven Storage section 25, one of the leading to the jobs 2 transverse transport sections 26 and the sleeve return path 27 shown.
  • the individual jobs 2 also have various facilities that ensure the proper operation of these jobs 2.
  • One of these devices is, for example, the winding device 4, which, as usual, has a coil frame 8 movably mounted about a pivot axis 12, in which the cross-wound bobbin 5 is held rotatably.
  • the cross-wound bobbin 5 during the winding operation also with its surface on a driven by an electric motor support and pressure roller 9, which carries the cheese 5 via frictional engagement.
  • Fadenchangier constructive 10 For traversing the thread 16 during the winding process a Fadenchangier constructive 10 is provided.
  • the thread traversing device 10 has a finger thread guide 13, which, acted upon by an electromechanical drive 14, traverses the thread 16 between the end faces of the cross-wound bobbin 5.
  • the drive 14 of the thread-changing device 10 like the electric motor of the drive support and pressure roller 9, is connected via control lines to the workstation computer 28, which in turn is connected via a bus connection 29 to the central control unit 30 of the winding machine 1.
  • the central control unit 30 may also, as in Fig.1 indicated to be connected via a connection 60 to an interface 61 of a ring spinning machine 40.
  • the individual jobs 2 also have, as known and therefore only hinted at, various devices which are also connected via appropriate control lines to the workstation computer and ensure proper winding operation of the jobs 2.
  • Such jobs 2 have, for example, a splicing device 19, a thread tensioner 20, a yarn cleaner 21, a paraffining device 22, a thread cutting device 23, a yarn tension sensor 31 and a lower thread sensor 32.
  • work stations 2 are equipped with a suction nozzle 17 and a gripper tube 18.
  • Fig.2 are shown schematically in front view two jobs of a ring spinning machine 40.
  • the jobs are identified by reference numerals 41A and 41B.
  • ring spinning machines 40 have, on each of their longitudinal machine sides, a stationary spindle bank 42 in which spinning spindles 43 are arranged at a pitch t, which are driven in the exemplary embodiment by means of a tangential belt 44.
  • a vertically adjustable mounted ring rail 45 is arranged, which, as indicated by the arrow 36A, by means of a (not shown) drive mechanism 'according to a predetermined spinning program is displaced.
  • spinning rings 46 are installed, in which, during the spinning operation, acted upon by the running thread 50, ring rotors 47 rotate.
  • a bank 48 for the balloon constriction rings 49 and a bank 51 for the thread guides 52 are arranged.
  • the work stations 41A and 41B of the ring spinning machine 40 are also provided with a drafting system 53, between the lower rollers 54 and support rollers 55, the fiber sliver 56 to be spun is drawn, preferably from a flyer spool (not shown) suspended in an associated gate.
  • the ring spinning machine 40 further has an interface 61 which communicates with the control device 62 of the ring spinning machine 40, which controls the position of the winding of the spinning cops, is in communication.
  • the interface 61 for example via suitable data carriers, a wide variety of information, for example concerning the optimum position of the winding of the newly produced spinning cops, can be transmitted to the control device 62.
  • a direct connection of the control device 62 of the ring spinning machine 40 to the control device 30 of the winding machine 1 can be realized.
  • the connection line is in the FIGS. 1 and 2 designated by the reference numeral 60.

  • the 3A shows a conventional spinning cop 3, that is a spinning cop, as it is known by the prior art.
  • a thread body 34 is fixed in the winding type "Kopswicklung" whose starting height, as indicated by the line 35, is very close to the sleeve foot.
  • approximately the lower third of the thread body 34 designated as a winding forms a so-called problem zone, that is to say a region in which, if no special measures are taken, the yarn tension increases greatly during the winding process.
  • the 3B shows a spinning cop 3 according to the invention, in which the starting height 35 for creating the winding 34 is significantly spaced from the sleeve foot.
  • Such trained spinning cops 3 have not only when unwinding on a job of a winder the advantage that they have no problem zone in which to avoid thread breaks during Umspulreaes must be worked with a significantly reduced Umspul für, but also offer advantages in their production on the job of a ring spinning machine. That is, for spinning heads with a relatively high winding does not need, as for example in the 3A Spinning jacks 3 are commonly used, after the start and in a large part of the lower Spinnkops Kunststoffs initially worked with reduced spinning speed, because due to the Spinnkops Symposium in this large thread balloon otherwise there is a risk of yarn breakage, but such spinning cops can be spun immediately at full working speed.
  • the relatively high start height 35 and the overall relatively high arrangement of the winding 34 on the spinning head sleeve 33 has the consequence that the setting at the start of the spinning thread balloon is relatively short, which makes it possible to operate the ring spinning machine immediately with full spinning speed ,
