  • the textile machines for the production of ring spinning cops usually have a large number of work stations, so-called spinning stations, in the area of the longitudinal sides of the machine.
  • these mostly identical jobs each have different working elements that are either mounted stationary or can be moved vertically.
  • a drafting system for drafting a template material provided by supply bobbins and a stationary spindle rail for receiving rotatably mounted ring spinning spindles are provided.
  • the feed bobbins preferably hang in the creel rows of a creel arranged above the ring spinning machine.
  • Textile machines of this type also have vertically displaceably mounted ring rails for receiving spinning rings and ring travellers, banks for balloon constriction rings and banks for thread guides.
  • a so-called single thread monitor can also be installed in the area of the spinning rings, which monitors the rotation of the ring traveler and detects if a thread breakage has occurred on a ring spinning spindle or if the ring traveler is rotating at too low a speed.
  • the vertically displaceable, usually machine-long components of the ring spinning machine are controlled by means of appropriate drive mechanisms and, in conjunction with the ring spinning spindles rotatably mounted in the spindle rail, ensure that a thread is spun from the feed material, which is wound onto a ring spinning cop according to a definable spinning program becomes.
  • the ring spinning bobbins manufactured at the workplaces of such ring spinning machines contain relatively little yarn volume, they are wound into large-volume cross-wound bobbins in a subsequent operation at the workplaces of winding machines. During this rewinding process, the threads running off the ring spinning cops are constantly monitored for thread defects and thread defects that exceed predeterminable limit values are cleaned out.
  • the work stations of such winding machines are equipped with various thread handling or thread processing devices.
  • the work stations of such winding machines each have, for example, a winding device arranged in the area of the upper side of the machine, in which a cheese is mounted during the rewinding process and rotated, for example, by friction, as well as a receiving device arranged in the area of the machine foot, in which the spinning cop is functionally positioned for rewinding can.
  • the workstations of such automatic cheese winders also have, among other things, a thread tension sensor, a thread tensioner and an electronic thread cleaner, with all thread monitoring devices being connected to a so-called workstation computer, which is also connected to the central control unit of the automatic cheese winder via a machine bus or the like.
  • electronic thread cleaners are also known from numerous patent applications.
  • the thread drawn off the ring spinning cop runs during the rewinding process on its way to the cheese, among other things, through the electronic thread cleaner, which continuously monitors the running thread during the rewinding process for thread defects, e.g. thick places, thin places, hairiness, thread impurities, etc . If the thread clearer detects a thread defect that exceeds the specified limit values, this is reported to the workstation computer, which ensures that the thread defect is immediately cleaned out and replaced with a thread splice that is almost identical to the yarn.
  • the thread faults detected by the electronic thread cleaner are also passed on to the central control unit of the winding machine by the workstation computer.
  • the winding speeds at which the work stations of winding machines work are limited due to various physical conditions, in particular due to the yarn tension forces occurring during the rewinding process. That is, during a rewinding process, in which the thread preferably by means of a rotating thread balloon is drawn off overhead from the ring spinning bobbin, the thread tension, starting from a relatively low value at the beginning of the bobbin travel, increases sharply in the course of the bobbin travel grow, which significantly increases the risk of yarn breakage.
  • the thread tension can vary greatly during the rewinding process of a ring spinning bobbin if the winding of the ring spinning bobbin has problematic areas, that is, in particular areas in which there is a sharp increase in thread tension.
  • the DE 43 06 095 A1 discloses an interconnected system of ring spinning machines and winding machines, in which the status data of the manufactured ring spinning cops are recorded on the ring spinning machines. The status data is then forwarded to the winding machine, where the treatment of each individual ring spinning bobbin delivered from the ring spinning machine to the winding machine is adapted to the status data recorded during the manufacture of this ring spinning bobbin on the ring spinning machine.
  • status data include, for example, yarn breaks that have occurred during the manufacture of the ring spinning cop in question.
  • the DE 10 2010 021 152 A1 relates to a method for the production of spinning bobbins, in which the position and size of the winding is determined by evaluating the ability of the spinning bobbin to be unwound when rewinding a spinning bobbin on a winding machine, transmitting the result to the ring spinning machine and using the control of the ring spinning machine to optimize the position the winding is processed.
  • the invention is based on the object of developing a method and a device which make it possible to influence the winding state of ring spinning bobbins manufactured at work stations of ring spinning machines in such a way that the ring spinning bobbins during subsequent rewinding at the work stations of Winding machines have the best possible run-off behavior.
  • This object is achieved according to the invention by a method for influencing the winding state of ring spinning bobbins manufactured on spinning stations of ring spinning machines according to a predetermined spinning program, which are rewound to form cross bobbins at work stations of a winding machine downstream in the production process, the threads running off the ring spinning bobbins being constantly monitored, thread defects registered and Yarn defects that exceed specified limit values are cleaned out, with data that are determined by the workstations of the winding machines during the rewinding processes of the ring spinning bobbins and that relate to thread defects in the ring spinning bobbins being transmitted back to the control device of the associated ring spinning machine and used there to optimize the winding status of new ring spinning bobbins , whereby problematic winding areas of the ring spinning cops are determined by means of the thread defects.
  • the movement of the ring rail performing a double stroke is adjusted on the ring spinning machine during the winding of the ring spinning cops in winding areas determined to be problematic,
  • the method according to the invention has the particular advantage that winding data, which are determined at the work stations of the winding machine during the rewinding processes of the ring spinning bobbins and which indicate that the winding state of the ring spinning bobbins is not entirely perfect, specifically problematic winding areas, are used to Spinning stations of the ring spinning machine to influence the winding process of subsequent ring spinning cops in terms of "improving the winding condition".
  • problematic winding areas of the ring spinning cops are determined by means of the yarn defects.
  • the control device of the ring spinning machine ensures, for example, that corrective measures are taken in the winding areas determined to be problematic in the following ring spinning cops to be produced.

  • the rotational speed of the ring spinning spindles is additionally reduced somewhat in winding areas of the ring spinning cops that are recognized as problematic.
  • problematic winding areas of the ring spinning cops can be effectively mitigated in a relatively simple manner. This means that these winding areas can be improved in such a way that thread defects are hardly registered when the ring spinning cops are subsequently wound at the work stations of the winding machine.
  • the spinning tension is additionally monitored at at least one of the work stations of the ring spinning machine and corrective intervention is made in the speed of the ring spinning spindles when a predeterminable limit value is reached.
  • Such an additional monitoring of the spinning tension can, for example, prevent a relatively large number of thread breaks or thread thin points occurring at the spinning positions of the ring spinning machine during the manufacture of the ring spinning cops due to excessive spinning tension, which have to be reworked at the work stations of the winding machine.
  • An advantageous embodiment is given when the data transmitted back to the ring spinning machine by the control device of the winding machine are combined in the control device of the ring spinning machine with the pulses of a single thread monitor and built up into a database for optimizing the winding status of new ring spinning cops.
  • the optimal spinning tension can be calculated from the impulses of the single thread monitor.
  • the winding state of future ring spinning cops can then easily be optimized by means of such a database.

Preferably, the winding speed at the work stations of the winding machine as a function of the Ring spinning machine detected end breaks adjusted. This makes it easier to clean out the thread defects on the winding machine.
  • the device for carrying out the method according to the invention is a ring spinning machine with a large number of work stations on which ring spinning bobbins are manufactured, the windings of which are created according to a predetermined spinning program.
  • the ring spinning bobbins produced on the ring spinning machine are then wound into cheeses at the work stations of a winding machine downstream in the production process, with the threads running off the ring spinning bobbins being constantly monitored and the data determined being processed in a control device of the winding machine.

Since there is also a control system that transmits back to the control unit of the ring spinning machine data that was determined by the work stations of the winding machine during the winding process and, for example, relates to thread defects in the ring spinning cops, the method according to the invention can be implemented in a simple and cost-effective manner.
