Definitions

  • the invention relates to a method for determining the coil diameter of cheeses on a cross-wound textile machine with a creel for holding a rotatable cheese, a defined controllable thread laying device for traversing a trailing yarn on the cheese and a defined controllable drive for rotating the cheese, both drives are independent of each other and the rotational speeds of the bobbin drive roller and the cross-wound bobbin are detected in order to calculate the ratio and finally the theoretical cheese diameter.
  • Textile machines producing cross-wound bobbins have been known for a long time and generally consist of a large number of similar workstations arranged in series next to one another.
  • a winder spinning cops which have relatively little thread material, rewound to large-volume cheeses.
  • Other textile machines such as rotor spinning, friction spinning or air spinning machines, which then allow in conjunction with spinning stations the winding of cheeses.
  • Thread supplier is then instead of a feed bobbin the corresponding spinning station.
  • Each of these workstations has various thread handling and thread monitoring devices, as well as a winding station computer, which is in connection with the thread handling and thread monitoring devices.
  • the individual Spulstellenrechner are in turn, preferably connected via a bus line to the central control unit of the cheese winding machine.
  • the cheese is an intermediate product which is processed in the further production processes of textile production. Therefore, not only to the yarn, but also to the structure of the cheese are high quality requirements.
  • a thread is wound continuously onto an initially empty bobbin tube so that the cheese gradually increases until, for example, it reaches a predetermined diameter.
  • the thread application per revolution of the cheese is extremely low compared to the diameter of the cheese.
  • the diameter of the cheese is an essential parameter that is used on the one hand to end the winding process when reaching a certain predetermined diameter or on the other hand make during the manufacture of the cheese interventions in the winding process to a quality coil, for example, with the most constant edge geometry, to obtain.
  • a winding apparatus of a package-forming textile machine and a method of operating a winding apparatus.
  • the winder described in this disclosure has a bobbin drive roller and a thread changer which are independently driven.
  • the speeds of the cross-wound bobbin and the bobbin drive roller are measured and transmitted to a workstation computer. With the two measured speeds and the diameter of the bobbin drive roller, which is known, the diameter of the cheese can be calculated.
  • a disadvantage of the method according to the prior art proves that due to the system results in a measured value which is greater than the actual diameter of the cheese, because between coil drive roller and cross-wound coil creates a slip that distorts the reading.
  • the erroneous diameter value determined in this way can lead to problems in the winding process, for example during run-up or edge geometry.
  • the period of the coil drive roller and the period of the cross-wound bobbin are continuously measured.
  • An evaluation is carried out in such a way that in the at least approximately slip-free phases of the measurement results, a comparison value is formed, in particular a quotient, which is compared with a desired value. If deviations to the setpoint occur, the winding process is intervened.
  • the evaluation is therefore carried out with measurement results from the phase-out phase, because here the slip goes to zero - whereas it is much larger in the acceleration phase and thereby falsifies the value to be calculated.
  • phase-out phases a slip-free drive takes place in cylindrical cheeses.
  • the so-called driven diameter in the outflow phase on the cheeses surface in the axial direction moves from the direction of the largest cheeses diameter in the direction of the smallest cheese diameter.
  • the driven cheese diameter is the diameter, wherein the peripheral speed of the cross-wound bobbin coincides with the peripheral speed of the bobbin drive roller.
  • the phase-out phase is referred to as a slip-free phase.
  • a winding machine in which the drive of a yarn guide differently than in the DE 37 03 869 C2 Separately done, requires no Stammstörbacter. Image wraps are prevented by means of a targeted control of the traversing speed of the yarn laying device.
  • the object of the present invention is to provide a method for determining the bobbin diameter of cheeses at a winding unit with separate drive of the thread guide, which allows the accurate and continuous detection of the actual cheese diameter.
  • the bobbin drive roller is cyclically switched on and off and that in the phase-out, while the bobbin drive roller is not driven, the rotational speeds of the bobbin drive roller and the cheese are detected, from the ratio and finally the actual To calculate cross-wound coil diameter.
  • the turn-off time required for this purpose is on the order of less than one second, in particular less than 0.5 seconds, and is sufficient to determine the exact and slip-free cheese diameter.
  • the cross-coil diameters are interpolated between the time-spaced measurements.
  • the actual slip is calculated from the cross-coil diameter in the slip phase and the cross-coil diameter in the run-out phase.
  • a further advantage of the solution according to the invention is the possibility of determining the current slip of the winding unit in the phase-out phases described by setting the diameter values with and without slip in relation to each other.
  • the drive of the bobbin drive roller is corrected on the basis of the actual slip.
  • the winding speed can be more precisely adjusted taking this value into account. Furthermore, it can be ensured that a specifiable slip is not exceeded.
  • the paraffin application is monitored based on the actual slip.
  • FIG. 1 is a side view schematically a winding unit 2 of a cheese-producing textile machine 1, in this case a so-called winder, shown.
  • Such winding machines 1 have, as is known, between their end frames, not shown, in each case a plurality of such winding units 2.
  • the spin creels 3 produced on an upstream ring spinning machine are rewound into large-volume cheeses 5, which after their completion by means of a service unit, not shown, such as a cheese changer, transferred to a machine-spooled cross-bobbin transport device 7 and be transported to a machine end side arranged Spulenverladestation or the like.
  • a service unit not shown, such as a cheese changer
  • Such winding machines 1 often also have a logistics device in the form of a bobbin and tube transport system 6.
  • the individual winding units 2 have, as is known and therefore only indicated, in each case via various devices which ensure the proper operation of such jobs.
  • One of these devices is, for example, the winding device identified by the reference numeral 4, which has a coil frame 8 movably mounted about a pivot axis 12.
  • the cheese 5 is located during the winding process with its surface 31 on a variable speed drive means, the so-called coil drive roller 9, and is carried along by this frictional engagement.
  • the traversing of the thread 16 during the winding process is carried out by a thread laying device 10.
  • thread laying device 10 has a finger-like thread guide 13, which, acted upon by an electromechanical drive 14, as in FIG. 2 indicated, the thread 16 traversed between the two end faces 32 of the cheese 5.
  • FIG. 2 how out FIG. 2 can be seen, the drive 14, a motor shaft 33 on which the finger-like thread guide 13 is arranged rotationally fixed.
  • the winding unit 2 further has a thread cleaner 22 which is connected via a signal line 29 to the winding station computer 28 and a in the
  • Section of the thread cleaner 22 arranged thread cutting device 23 which is controllable via a line 30 from the winding station computer 28.
  • a yarn tensile force sensor 20 is also provided, which is connected via a signal line 21 to the winding station computer 28.
  • the cross-wound bobbin 5 lies with its surface 31 on a bobbin drive roller 9.
  • the coil drive roller 9 is defined by an electromagnetic drive 34 which is connected via a control line 19 to the winding station computer 28, driven and takes the cheese with frictional.
  • the thread 16 traverses on its way to the cheese 5 at least the thread cleaner 22 and the thread cutting device 23rd
  • the running thread 16 which is monitored by the thread cleaner 22 for thread error, generated in the thread cleaner 22, inter alia, a dynamic yarn running signal, which is transmitted via the signal line 29 to the winding station computer 28.
  • both the rotational speeds of the bobbin drive roller 9 and the cross-wound bobbin 5 are detected in the winding station computer 28 and calculates the theoretical cross-wound coil diameter with slip.
  • the drive 34 of the bobbin drive roller 9 is switched off for 0.5 seconds every five seconds.
