Definitions

  • the present invention is in the field of thread winding into shape a coil, which process also as winding or as the production of a winding referred to as.
  • a second coil is made from a first coil
  • the speaker speaks one also of rewinding, whereby in the winding of a textile company predominantly this Rewinding takes place.
  • the winding or winding of a thread is known to be done with winding machines that work according to different winding laws and thereby either a wild winding or make a precision winding or a step precision winding.
  • the relevant Spool parameters are in particular the so-called turn ratio (number of spool revolutions per double stroke), the pitch angle determined by the turns ratio the thread laying, which corresponds to half the crossing angle, and the Speed.
  • Wild winding is understood to mean windings whose turns ratio increases with increasing Coil diameter decreases continuously, with the crossing angle constant remains.
  • the constant crossing angle over the entire coil diameter has one good dimensional stability and transportability of the coil produced in this way.
  • disadvantage arise due to unfavorable number of turns, which occur during the coil build-up at certain Make coil diameters noticeable as so-called images or image zones.
  • images or image zones In these zones, thread is placed directly next to thread or even thread on thread. The consequence of these image zones is an uneven yarn development, which can later lead to tension peaks during unwinding.
  • the image zones represent a very serious disadvantage.
  • the turns ratio remains during the entire winding process constant.
  • the crossing angle changes and increases with increasing coil diameter Sharpener.
  • a precision-wound coil knows with an optimally selected number of turns no image zones, which results in very good printing properties.
  • the dimensional stability due to the change in the pitch angle over the coil structure the thread laying is not so good.
  • the step precision winding represents a combination of the two winding laws, wild Winding and precision winding.
  • Winding machine will combine the advantages of these two winding laws achieved that in a winding machine with a driven by a motor drive Driving roller and with a driven by a gear with variable ratio Thread laying to produce a precision winding the drive roller of one Fixed ratio drive and the transmission for thread laying is adjusted by an actuator controlled by a computer, each with a speed sensor for measuring the speed of the package and thread laying with the Computer is connected.
  • the turns ratio is specified and after the crossing angle has been decreased the computer switches to a predetermined amount by a predetermined amount lower number of turns. This creates concentric rings with precision winding, the number of turns from ring to ring with increasing coil diameter abruptly discreet specified value so that the crossing angle only in narrow limits.
  • the approximately constant crossing angle corresponds to one wild winding and maintaining the turns ratio in diameter steps a precision winding.
  • the invention relates to a method for winding at a constant speed delivered thread by means of a thread traversing device to a bobbin with precision or step precision winding.
  • the method according to the invention is intended to be used on yarn-producing or yarn-treating machines, in particular on spinning machines of all kinds, should be suitable and the manufacture of precision or step precision windings enable directly on these machines.
  • the device should be so inexpensive to carry out the method according to the invention that it can be used in large numbers on the machines mentioned.
  • the object is achieved according to the invention in that the speed the bobbin and the speed of thread traversing are controlled so that the speed of the thread is constant regardless of the pitch angle of the thread laying remains.
  • the invention further relates to a device for performing the inventive Method, with a bobbin drive, a drive for the thread traversing device and with a controller assigned to these drives.
  • the device according to the invention is characterized in that the controller the values for the thread speed and the winding parameters are supplied, and that in the controller a calculation the pitch angle of the thread laying and that for maintaining a constant Thread speed required with changing pitch angle of the thread laying required Speed of the bobbin and thread traversing takes place.
  • the invention also relates to a device for carrying out the process according to the invention Process on one central drive shaft for the individual production units containing process machine, with a drivable by the central drive shaft Driving cylinder for the bobbin and a drive for the thread traversing device.
  • each drive cylinder a servo motor is assigned, by means of which the one supplied by the central drive shaft Speed of the drive cylinder a speed is superimposed so that one of the desired Peripheral speed of the coil corresponding speed of the drive cylinder results.
  • This embodiment has the advantage that all transmissions of the movements are positive, So realized without slippage and therefore no sensors for speed monitoring required are.
  • the planetary gear can be designed so that the servo motor only a small part of the power required for the coil drive must deliver. This allows the use of a relatively weak motor accordingly low cost.
  • a second preferred embodiment of the device according to the invention is thereby characterized in that the drive cylinder is mounted on the central drive shaft and is driven by a conoid gear, one of which has a conoid with the central one Drive shaft is firmly connected and via a movable by the servo motor Belt drives the other conoid connected to the drive cylinder.
  • the device shown schematically in FIG. 1 essentially consists of a thread feed mechanism 1, which receives a thread F to be wound from a process P. and to a thread traversing device 2, which feeds the thread F through one Motor 3 driven coil sleeve 4 coils, whereby a coil 5 is formed.
  • the Thread traversing device 2 comprises, as shown, a thread guide 6 which a string or belt 7 is driven by a motor 8.
  • the thread traversing device 2 and the coil sleeve 4 with the motor 3 form a winding unit, which here is not described in detail.
  • EP-A-0 453 622 EP-A-0 828 444, EP-A-0 838 422 and to the preciflex thread laying marketed by Schrer Schweiter Mettler AG.
  • the motor 3 for the bobbin drive and the motor 8 of the thread traversing device 2 are connected to a control unit 9, which includes a microprocessor or Microcontroller contains, and in which the various winding parameters can be entered.
  • a control unit 9 which includes a microprocessor or Microcontroller contains, and in which the various winding parameters can be entered.
  • sensors (not shown) for the speed of the motor 8 and the position of the thread guide 6 and provided for the speed and position of the motor 3, which are also connected to the control unit 9.
  • the process designated by P in FIG. 1 stands for any yarn manufacturing or yarn treatment method, for example a spinning or texturing method, by means of which the thread F is delivered at a constant speed V G. From this thread, for example, a spool with precision or step precision winding is now produced directly on a spinning machine and bypassing the rewinding process previously required, precision winding meaning that the turns ratio remains constant during the winding process.
  • the pitch angle of the thread laying or crossing angle changes according to the constant turn ratio and becomes more acute with increasing bobbin diameter. This crossing angle is designated in FIG. 1 by the reference symbol 2 ⁇ and is drawn on the coil 5.
  • FIG. 2 shows a diagram in which the speed V F of the thread guide 6 is entered on the abscissa, the rotational speed V S of the bobbin 5 and the thread speed V G determined by these two speeds are entered on the ordinate, the thread speed with the abscissa Inclination angle ⁇ includes. If the slope angle ⁇ changes and, for example, the value ⁇ should assume, then the speeds mentioned would have to be changed accordingly. As can be easily seen, two of the speeds have to be changed and one can remain constant. 2, the thread speed V G is kept constant and the speeds V F and V S of the thread guide 6 or the bobbin 5 are adapted to the changed orientation of the vector V G caused by the change in the pitch angle ⁇ .
  • This adaptation takes place in that the microprocessor contained in the control unit 9 from the entered winding parameters and from the diameter of the coil 5 the respective instantaneous value of the pitch angle and the corresponding position of the vector of the thread speed V G and from this and from the amount supplied by the thread delivery mechanism 1 V G calculates the respective values for the speed V F of the thread guide 6 and the speed V S of the bobbin 5 and controls the motors 8 and 3 accordingly.
  • FIG. 3 shows the arrangement of the winding device on a central drive shaft Process machine shown
  • Figures 4 and 5 each show an embodiment for the coil drive derived from the central drive shaft.
  • the winding device shown in FIG. 3 differs from that shown in FIG. 1 essentially in that the coil 5 does not come from a driving the coil sleeve 4 Motor (Fig. 1) is driven, but by one of the central drive shaft 11 of the relevant process machine driven drive cylinder 12.
  • the process machine is a yarn production or treatment machine, for example one Spinning or texturing machine.
  • the reference symbol A is closer to that in FIGS. 4 and 5 shown, individually controllable drive of the drive cylinder 12.
  • Of the Drive cylinder 12 is rotatably mounted on the central drive shaft 11 in both cases and has an internal toothing.
  • the individually controllable drive of the coil 5 takes place via a planetary gear between the central drive shaft 11 and the drive cylinder 12.
  • a sun gear 13 is fixedly connected to the central drive shaft 11, the rotation of which is transmitted to the drive cylinder 12 with a planet gear 14.
  • the planet gear 14 is carried by a web 14 ', which can also be driven by a servo motor 15 via a drive wheel 16.
  • the speed of the servo motor 15 is selected so that a speed is superimposed on the drive wheel 16 for the web 14 'of the planetary gear 14 so that the speed of the drive cylinder 112 and thus the peripheral speed of the bobbin 5 corresponds to that for the constant thread speed V G (FIG 2) Required value reached.
  • the embodiment shown in Fig. 4 has the advantage that all movement transmissions positively, that is, realized without slip. Since the translations of a planetary gearbox are therefore not sensors for speed monitoring required. In addition, the servo motor 15 needs with an optimal design of the planetary gearbox only a small part of those required for the coil drive To deliver power, making a relatively weak engine with a correspondingly low cost can be used.
  • a conoid gear is used instead of the planetary gear used, of which a conoid 17 is fixedly arranged on the central drive shaft 11 is and drives the other conoid 19 via a flat belt 18, which in Engagement with the internal toothing of the drive cylinder 12 is.
  • the belt 18 is actuated by a servomotor 15, bracket-like or fork-like adjusting element 20 can be displaced along the surface of the conoid. Since this system works with frictional connection, the speed of the Driving cylinder 12 with a sensor (not shown) required. Because the shift of the flat belt 18 requires only a small amount of force, which requires the Sensor drive 16 forming motor only a relatively low power here.
