Definitions

  • the invention relates to a winding unit for a cheese manufacturing textile machine according to the preamble of Claim 1.
  • CH-PS 542 781 describes, for example, a winding unit of a precision cheese winder with a rotatably mounted bobbin holding mandrel for the supply bobbin.
  • the coil holding mandrel is connected via a drive belt to a drive drum which is mounted on a machine-long, constantly rotating drive shaft and can be selectively connected to the drive shaft via an electromagnetic clutch. If the diameter of the winding spool, which is directly driven by a drive spindle, e.g. a package, has reached a predetermined dimension and a high thread take-off speed has been reached, a corresponding device ensures that the spool receiving mandrel of the supply spool is rotated counter to the unwinding direction of the thread.
  • a comparable device is also known from FR-PS 1.450.896.
  • a supply spool in the form of a spinning cop is arranged during the rewinding process on a rotatably mounted spool take-up mandrel, which is connected to a machine-long, drivable shaft via a belt arrangement and can be rotated in a defined manner.
  • DE 38 43 928 A1 describes a winding unit in which the bobbin holding mandrel for the supply bobbin can be rotated pneumatically.
  • a brake device is also assigned to the spool, which is automatically activated as soon as the compressed air supply for the drive is switched off.
  • a device which makes it possible to unwind a certain amount of winding material per unit of time from a spool.
  • the winding material is unwound with the greatest possible protection of the winding material and with even tension conditions.
  • the known device has a winding arm mounted rotatably above the winding material spool, which can be acted upon in a defined manner by a speed-adjustable drive.
  • the winding arm is angled downward, that is to say towards the center of the bobbin, and has a measuring wheel and a thread tension measuring device at the end.
  • the winding material coming from the coil is scanned and an output signal characterizing the running speed of the winding material is generated, which is synchronized with the speed of the winding arm drive.
  • the winding material spool can be rotated against the unwinding direction while the winding material is being unwound.
  • the device has proven itself in practice in the case of coils which are wound at relatively low take-off speeds.
  • the device is hardly suitable for higher thread take-off speeds, not least because of the not inconsiderable centrifugal mass of the rotating winding arm and the associated counterweight.
  • the Invention Based on the aforementioned prior art, the Invention based on the object of developing a winding unit with both the thread tension during the rewinding process significantly reduced, as well as ensuring that it not in the form of thread detachments during the rewinding process comes from slings.
  • the inventive design and arrangement of a thread unwinding device with a thread deflecting element which is arranged eccentrically to the bobbin axis and adjacent to the part of the bobbin winding in the unwinding position during the unwinding of the thread ensures that the thread during the entire bobbin travel with respect to the bobbin axis is handled almost orthogonally. That is, during unwinding, it is reliably prevented. circumferential, the thread tension increasing thread balloon can adjust.
  • the even, almost orthogonal unwinding of the thread from the surface of the supply spool not only has a positive effect on the thread tension, which is significantly reduced and is almost constant during the entire rewinding process, but also prevents the loops of thread from detaching from the supply spool.
  • critical thread pulling forces are only achieved at significantly higher thread take-off speeds than is the case with the winding units known to date.
  • the thread deflecting element is advantageously always at least partially positioned below the sleeve tip of the supply spool during rewinding. Such an arrangement also ensures that a disadvantageous thread balloon cannot arise at any point in the rewinding process.
  • the thread deflecting member is arranged to be displaceable parallel to the bobbin axis. Such an embodiment enables a defined tracking of the thread deflection element in accordance with the unwinding progress. In this way, the thread is unwound from the supply spool without additional deflection and thus relatively gently.
  • Thread deflecting member advantageously mounted so that when Unwinding the supply reel fluctuations of the Thread unwinding speed automatically, preferably through Change the distance between the thread deflector and Coil axis of the supply coil are compensated.
  • the thread deflecting member is, for example, slidably arranged on a corresponding bearing arm, as described in claim 7.
  • the thread deflecting member is acted upon by a spring element which works against the tensile force of the thread. This means that when the thread tension decreases, the thread deflection element is displaced away from the supply bobbin, while an increase in the thread tension force automatically leads to the distance between the thread deflection element and the bobbin axis of the supply bobbin being reduced.
  • the thread deflecting member is connected via a bearing arm to a guide carriage which is in turn slidably mounted on or in the bobbin case housing via a corresponding drive device parallel to the bobbin axis of the supply bobbin.
  • the thread deflecting element is designed as a deflecting roller.
  • the deflection roller as described in claim 9, is freely rotatable, for example, via a smooth-running roller bearing.
  • a freely rotatably mounted deflection roller ensures, on the one hand, a gentle deflection of the drawn-off thread and, on the other hand, has hardly any negative effect on the thread pulling force.
  • such freely rotatably mounted deflection rollers are relatively inexpensive, since both the deflection rollers and the associated roller bearings are commercially available as large series parts.
  • the deflection roller as set out in claim 10, can be driven in a defined manner by means of an individual drive.
  • Such a single-motor driven deflection roller has, for example, the advantage that the thread tension can be influenced via the deflection roller.
  • Figure 1 is a side view schematically Job 1 one with the reference number 22 marked cheese making textile machine shown.
  • Textile machines of this type usually have a large number of such work stations 1 arranged in a row.
  • supply spools 2 usually spinning bobbins, which were produced, for example, on ring spinning machines (not shown), are rewound to form large-volume cross-wound bobbins 13.
  • the work stations 1 are equipped with various, known and therefore only schematically illustrated thread handling and testing devices, each of which can be controlled in a defined manner by a work station control device, a so-called winding station computer 5.
  • the thread 3 drawn from the supply spool 2 runs on its way to the package 13, which is rotatably mounted in a spool frame 14 and is frictionally driven during winding operation via a so-called thread guide drum 12, initially via the thread unwinding device 4 according to the invention.
  • the thread 3 then passes through a thread tensioner 6, a thread cleaner 8 with an associated thread cutting device 9 and an optional paraffinizing device 10.
  • a thread splicing device 7 is also arranged outside the "regular" thread path 30.
  • a suction nozzle 15 and a gripper tube 19 are also provided for handling the thread ends in the event of a thread break or a defined cleaner cut.
  • the suction nozzle 15 is about a pivot axis 17, the Gripper tube 19 rotatably mounted about a pivot axis 21. Both the suction nozzle 15 and the gripper tube 19 can, like Known, applied with negative pressure when required become.
  • the supply spool 2 is rotatably mounted in its unwinding position 16 and can be rotated in the R direction by a preferably frequency-controlled drive 11 with an adjustable speed.
  • a fast-acting braking device 18 is also installed, which brakes the supply spool 2 to a standstill immediately in the event of a cleaner cut or a thread break.
  • Thread unwinding device 4 is shown in more detail in Figure 2.
  • the thread unwinding device 4 has a thread deflection element, preferably in the form of a freely rotatably mounted deflection roller 23 or a deflection roller 23 defined by means of a drive 32.
  • the deflection roller 23 is arranged on a height-adjustable bearing device and positioned during the winding process so that the deflection roller 23 is both off-center to the coil axis 33 of the supply spool 2 and at least partially below the sleeve tip 35 of the supply spool 2.
  • the deflection roller 23 is connected, for example, via a bearing arm 24 to a guide slide 25 which, mounted in a corresponding guide 31, can be displaced parallel to the coil axis 33 of the supply spool 2 by means of a corresponding drive device 29.
  • the guide 31 is arranged in or on the winding unit housing 34 of the winding unit 1 concerned of the cross-wound bobbin textile machine 22. This means that the deflection roller 23 can be continuously lowered during the rewinding process in such a way that the thread 3 is always unwound almost orthogonally from the surface of the supply spool 2.
  • the deflection roller 23 is also mounted such that the distance a between the axis of rotation of the deflection roller 23 and the bobbin axis 33 of the supply bobbin 2 is changeable. That is, the deflection roller 23 is arranged, for example, on a front bearing arm part 24A, which is axially displaceable with respect to a rear bearing arm part 24B. Between the bearing arm parts 24A and 24B, a spring element 36 is connected, which acts on the deflection roller 23 slightly against the thread tension.
  • a pneumatic thread store could also be used, for example.
  • a pneumatic thread store could, for example, have a storage tube that can be subjected to negative pressure, the filling status of which is constantly monitored by appropriate sensors.
  • fluctuations in the thread unwinding speed can be compensated for by temporarily storing the thread length by adapting the negative pressure in the storage tube.
