Definitions

  • the invention relates to a winding unit for a cheese-producing textile machine according to the preamble of claim 1.
  • the CH-PS 542 781 describes, for example, a winding unit of a precision spooling machine, with a rotatably mounted spool receiving mandrel for the supply spool.
  • the bobbin receiving mandrel is connected via a drive belt with a drive drum in connection, which is mounted on a machine-length, constantly rotating drive shaft and can be selectively connected via an electromagnetic clutch to the drive shaft. If the diameter of the directly driven by a drive spindle bobbin, such as a cheese, has reached a predetermined level and thus a high yarn withdrawal speed is reached, a corresponding device ensures that the Spulenaufnahautorn the supply bobbin is rotated counter to the unwinding of the thread.
  • a comparable device is also known from FR-PS 1,450,896. Also in this device, a feed bobbin in the form of a spinning cop is arranged during the rewinding process on a rotatably mounted bobbin receiving mandrel, which is connected via a belt arrangement with a machine-long, drivable shaft and can be rotated in a defined manner.
  • a winding unit is described in DE 38 43 928 A1, in which the Spulenadapteddorn for the supply spool can be pneumatically rotated.
  • the bobbin receiving mandrel is also associated with a braking device, which is automatically activated as soon as the compressed air supply for the drive is turned off.
  • a device which makes it possible to unwind from a coil a certain amount of winding material per unit time.
  • the unwinding of the winding material takes place under the greatest possible protection of the winding material and at uniform stress ratios.
  • the known device has a winding arm rotatably mounted above the winding reel, which can be acted upon defined by a variable speed drive.
  • the wrapping arm is downwards, that is, angled towards the center of the coil and has at the end a measuring wheel and a yarn tension measuring device.
  • This measuring wheel coming from the coil winding material is scanned and a running speed of Winding characteristic identifying output signal generated, which is synchronized with the speed of the Wickelarmantriebes.
  • the Bickelgutspule be rotated against the unwinding during unwinding of the winding material.
  • the device has been proven in practice with winding material coils which are unwound at relatively low Wickelgutabzugs Anlagenen.
  • the device for higher yarn withdrawal speeds, the device, however, hardly suitable, not least because of the not insignificant flywheel of the rotating wrapping arm and the associated counterweight.
  • the present invention seeks to develop a winding unit, in which both the yarn tension significantly reduced during the rewinding, and also ensures that it does not come to thread detachment in the form of loops during Umspulreaes.
  • Fadenabwickel which is arranged off-centered during the unwinding of the thread from the supply spool to the bobbin axis and adjacent to the unwinding position in the Kopswicklung, it is achieved that the thread during the entire coil travel with respect to the coil axis is wound almost orthogonal. That is, during the unwinding is reliably prevented from becoming. circumferential, the thread tension increasing thread balloon can adjust.
  • the Fadenumlenkorgan is arranged parallel to the coil axis slidably.
  • Such an embodiment enables a defined tracking of the Fadenumlenkorgans according to the unwinding progress.
  • the thread is unwound in this way without additional deflection and thus relatively gently from the feed bobbin.
  • the Fadenumlenkorgan is advantageously always positioned at least partially below the sleeve tip of the supply spool during rewinding. Such an arrangement also ensures that at no time during the rewinding process can an adverse yarn balloon result.
  • the Fadenumlenkorgan is advantageously stored so that the unwinding of the supply bobbin fluctuations in Fadenabwickel economically automatically, preferably by changing the distance between Fadenumlenkorgan and coil axis of the supply spool, are compensated.
  • the Fadenumlenkorgan example as described in claim 6, slidably disposed on a corresponding bearing arm.
  • the Fadenumlenkorgan is acted upon by a spring element which operates against the tensile force of the thread. That is, with decreasing yarn tension the Fadenumlenkorgan is displaced away from the supply spool, while an increase in the yarn tension automatically causes the distance between Fadenumlenkorgan and coil axis of the supply spool is reduced.
  • the Fadenumlenkorgan is connected via a bearing arm with a guide carriage, which in turn is slidably mounted via a corresponding drive means parallel to the coil axis of the supply spool on or in the winding head housing. That is, the Fadenumlenkorgan can be defined over the guide carriage during the entire Umspulreaes so tracked that due to the flow angle of the thread from the surface of the supply bobbin optimal Abwickelixie are always given. These optimal Abwickelixie of the thread have a positive effect by a significant reduction in the yarn tension.
  • the Fadenumlenkorgan as set forth in claim 7, designed as a deflection roller.
  • the deflection roller is, as described in claim 8, for example, freely rotatably mounted on a readily available rolling bearing.
  • a freely rotatably mounted pulley ensures on the one hand a gentle deflection of the withdrawn yarn and on the other hand has hardly any negative effect on the yarn tension.
  • freely rotatably mounted pulleys are relatively inexpensive, since both the pulleys and the associated bearings are available as mass production parts in the trade.
  • the deflection roller as set forth in claim 9, defined by a single drive driven.
  • a single motor driven pulley for example, has the advantage that on the pulley influencing the yarn tension is possible.
  • FIG. 1 schematically shows, in a side view, a workstation 1 of a textile machine producing cross-wound bobbins, generally designated by the reference numeral 22.
  • Such textile machines usually have a plurality of such arranged in series jobs.
  • 1 On the jobs 1 supply bobbins 2, usually spinning cops, which were for example made on (not shown) ring spinning machines, rewound to large-volume cheeses 13.
  • the workstations 1 are equipped for this purpose with various known and therefore only schematically illustrated Fadenhandhabungs- and -prüf docken, each defined by a workstation's own control device, a so-called winding station computer 5, are controlled.
  • the withdrawn from the supply spool 2 thread 3 runs on its way to the cheese 13, which is rotatably mounted in a creel 14 and frictionally driven during the winding operation via a so-called Faden arrangementstrommel 12, first on the invention Fadenabwickel sensible 4.
  • the thread passes through 3 then below another thread tensioner 6, a thread cleaner 8 with an associated thread cutting device 9 and an optional paraffining device 10th Outside the "regular" yarn path 30 also a yarn splicing device 7 is arranged.
  • a suction nozzle 15 and a gripper tube 19 are also provided.
  • the suction nozzle 15 is rotatably mounted about a pivot axis 17, the gripper tube 19 about a pivot axis 21. Both the suction nozzle 15 and the gripper tube 19 can, as known, be subjected to negative pressure when required.
  • the feed bobbin 2 is rotatably mounted in its unwinding position 16 and can be rotated by a, preferably frequency-controlled drive 11 with adjustable speed in the direction R.
  • a fast-acting braking device 18 is installed, which brakes the feed spool 2 immediately to a standstill in a cleaner cut or a thread break.
  • the yarn unwinding device 4 shown only schematically in FIG. 1 is shown in greater detail in FIG.
  • the Fadenabwickel worn 4 a Fadenumlenkorgan, preferably in the form of a freely rotatably mounted or a defined by a drive 32 rotatable guide roller 23.
  • the guide roller 23 is arranged on a height-adjustable bearing device and positioned during the winding process so that the guide roller 23 is both eccentrically to the coil axis 33 of the supply spool 2 and at least partially below the tube tip 35 of the supply spool 2.
  • the guide roller 23 is connected for example via a bearing arm 24 to a guide carriage 25 which, mounted in a corresponding guide 31, by means of a corresponding drive means 29 parallel to the coil axis 33 of the supply spool 2 is displaceable.
  • the guide 31 is arranged in or on the winding head housing 34 of the respective winding unit 1 of the cheese-producing textile machine 22 is arranged. That is, the guide roller 23 is continuously lowered during the rewinding so that the thread 3 is always almost orthogonal unwound from the surface of the supply spool 2.
  • the guide roller 23 is also mounted so that the distance a between the axis of rotation of the guide roller 23 and the coil axis 33 of the supply spool is changeable. That is, the pulley 23 is arranged, for example, on a front Lagerarmteil 24 A, which is axially displaceable with respect to a rear Lagerarmmaschines 24 B. Between the Lagerarmmaschine 24A and 24B while a spring element 36 is turned on, which acts on the guide roller 23 slightly against the yarn tension.
  • a pneumatic thread store could be used instead of a mechanical thread store.
  • a pneumatic yarn store could, for example, have a vacuum-pressurized storage tube whose filling state is constantly monitored by corresponding sensors. That is, in such pneumatic thread stores can be compensated for fluctuations in the Fadenabwickel (2004) by appropriate intermediate storage of thread length by adjusting the negative pressure in the storage tube.
