Definitions

  • the invention relates to a winding device for a workstation of a cross-wound textile machine according to the preamble of claim 1.
  • Winding machines of textile machines which serve for the production of cheeses, must be known to fulfill at least two basic conditions. Firstly, such winding devices must have a device which makes it possible to set a sleeve or a cheese into rotation, that is, to rotate so that a thread can be wound up; on the other hand, there must be a device which allows the thread to be constantly traversed during winding - this means to constantly change the thread between the package sides of the package.
  • winder devices In connection with automatic spooling machines, for example, winder devices have long been known in which the sleeve or cross-wound bobbin is frictionally driven by means of a so-called slot drum.
  • slot drum For example, in these DE 195 46 539 A1 Spulvorraumen described rotatably held in a creel mounted cross-wound bobbin with its surface on a drivable groove drum and is carried along by this during the winding operation via frictional engagement.
  • a thread guiding groove embedded in the groove drum ensures that the thread is changed according to the rules between the two coil sides of the package.
  • a winding device whose Fadenchangier noticed has a finger-like thread guide with an end arranged guide fork for traversing the thread.
  • the thread guide is pivotable about an axis of rotation oriented substantially perpendicular to the cheese axis and is acted upon by an electromechanical single drive.
  • the rotation of the cheese is done in this known winding device either by friction via a single motor acted upon drive roller or a drive device not described in detail, in which a single drive is integrated into the creel. That is, the single drive acts on one of the sleeve plates, between which the cross-wound bobbin is mounted, rotate in the sense.
  • a yarn guide with tape drive that is, a changierbarer yarn guide is connected via a finite, flexible connecting means to an electric motor single drive.
  • the finite, flexible connecting means is designed so that it can transmit both tensile and compressive forces.
  • winding devices in which the cheese, as described above, during the winding process by means of a drive roller rotates and trailing yarn is traversed simultaneously by a separately driven yarn guide between the two coil sides have the disadvantage that in such winding devices during the winding process relatively large following errors are unavoidable. That is, the conditional by the drive roller, relatively large distance between the yarn guide and the casserole point of the thread on the rotating surface of the cheese causes that during the winding process, the yarn feeding point always remains well behind the position of the yarn guide.
  • This thread length which results between the deflection point of the thread on the thread guide and the point of emergence of the thread on the rotating surface of the cross-wound bobbin is, as already explained above, usually referred to as lag error in professional circles.
  • Such winding devices in which the cross-wound bobbin is driven directly, that is, in which one of the two rotatably mounted on the coil frame arms of the creel tube sleeve receiving plate is connected directly to a variable speed drive, are for example in the DE 43 10 905 A1 or in the DE 43 30 647 A1 be-written.
  • the present invention seeks to improve the known winding devices so that during the winding process in a relatively simple manner, a significant reduction in the size of the drag error occurring can be achieved.
  • the bobbin tube of a cross-wound bobbin is fixed between the bobbin receiving plates of a creel, wherein one of the bobbin receiving plates can be acted upon by a drive device integrated into the creel, for example.
  • the creel is also equipped with a defined controllable, subject to single motor coil frame positioning. This bobbin frame positioning device ensures that the cross-wound bobbin held in the bobbin frame is positioned at a distance apart from the thread baffle device during the bobbin winding process.
  • the bobbin frame positioning means ensures throughout the bobbin travel of the cheese a constant distance a between the Fadenchangier immunity and the surface of the cheese, which in particular has the advantage that can be completely dispensed with the hitherto necessary use of a support roller or the like ,
  • This means that the possible absence of a back-up roller or the like on account of the use of the inventive creel-positioning device makes it possible to position the thread-changing device significantly closer to the surface of the cheese, which leads to winding devices which work according to the invention with significantly minimized following errors. With the winding devices according to the invention, therefore, high-quality cheeses can be produced in a relatively simple and cost-effective manner.
  • a Fadenleitkontur is arranged, whose clear distance from the cheese corresponds to the distance a.
  • the distance a on the one hand must be large enough to avoid contact of the moving coil surface to the guide contour, on the other hand be so small for the reasons mentioned above, so it should advantageously be between 0.5 and 3 mm depending on the Spulparametern.
  • Fadenleitkontur which is preferably as described in claim 3, attached to the housing of the Fadenchangier worn and having a convex yarn guide surface, during the Fadenchangierens a relatively good uniformity of the yarn running speed when winding the yarn can be achieved on the cheese. That is, by the convex yarn guide the Fadenleitkontur fluctuations in the yarn running speed, as they occur in the traversal of a running on a cross-wound yarn, at least partially balanced and thereby the occurrence of yarn tension peaks during the winding process are largely avoided.
  • Fadenleitkontur is not mandatory. Basically, with a corresponding modification of the yarn guide, an operation of the winding device according to the invention.Also possible without such Fadenleitkontur.
  • the Fadenchangier driving is arranged in an advantageous embodimentType that at the beginning of the coil travel of a cheese, viewed in side view of the winder, between the plane of the changeable yarn guide and the planes of the coil frame arms is given an angle whose value between + 10 ° and - 10 °.
  • Practical experiments have shown that a particularly advantageous embodiment is given when, as set forth in claim 5, the FadenchangierISS is arranged so that at the beginning of the coil travel a cheese the plane of the changeable yarn guide runs parallel to the planes of the coil frame arms.
  • the creel-positioning device has a built-in the work place housing a job, acted upon by a controllable stepper motor reduction gear.
  • a reduction gear can be acted upon by a stepping motor is basically known in a comparable embodiment in connection with winding devices in which the contact pressure of a held in a creel, resting on a bobbin drive roller cheese to be kept constant and, for example in the DE 100 60 237 A1 described.
  • the reduction gear has been slightly modified compared to the known device, that is, for example, was dispensed with the use of spring elements as a torque sensor and instead switched the reduction gear directly to the pivot axis of the coil frame.
  • a pressure roller In the area of the winding device, spaced apart from the thread-changing device, for example, a pressure roller is installed, which is arranged so that the floating cross-wound bobbin can be subjected to a predeterminable pressing force during the bobbin travel (claims 7).
  • a pressure roller With regard to the storage of such a pressure roller very different embodiments are possible.
  • the pressure roller may for example be connected via a bearing arm to an adjusting device arranged on the creel that, if necessary, an optimal adjustment of the pressing force of the pressure roller is possible via this adjusting device.
  • an adjusting device arranged on the creel that, if necessary, an optimal adjustment of the pressing force of the pressure roller is possible via this adjusting device.
  • the pressure roller is preferably arranged on the side opposite the Fadenchangier adopted the cross-wound bobbin (Anspr.8).
  • Such an arrangement not only makes it relatively easy to prevent obstructions in the area of the thread-changing device, but such an arrangement also offers sufficient space for a separate pressure-roll-applying or -beaufschlagungs noticed (not shown).
  • a pressure roll applying or -beaufschlagungs might have a pressure roller bearing, which is equipped with compression springs or the like.
  • the spring force is adjustable, for example, the force with which the pressure roller acts on the cheese during the winding process , be set relatively accurately.
  • the pressure roller may also have a sensor device for determining the rotational speed of the pressure roller (Anspr.9).
  • a sensor device for determining the rotational speed of the pressure roller (Anspr.9).
  • the thread-traversing device which traverses the incoming thread between the coil sides of the cross-wound bobbin during the winding process, can have different embodiments.
  • the Fadenchangier dressed is equipped for example with a finger thread guide.
  • a finger thread guide With such in the textile industry known and proven Fingerfaden existedn not only relatively high traversing speeds can be realized, but such Fingerfadenraising are also very flexible in connection with winding devices. That is, with such a finger thread guides can be produced, for example, cross reels of different widths and / or with different shapes, for example, straight, conical or biconical cheeses.
  • the Fadenchangier realized a reversibly drivable yarn guide, which is connected to a finite, flexible connecting means which can transmit both tensile and compressive forces. That is, on a finite, flexible connecting means, such as a spring steel strip, which is acted upon by a reversible electric motor drive and linearly guided in the traversing range, a yarn guide is attached, which has a distance a to the surface of a rotating cheese during the winding process.
  • the Fadenchangier worn on a yarn guide which, as known for a long time, is connected to a Endlosriemchen, which in turn is in communication with a reversible electric motor drive.
  • the yarn guide according to claim 12 has a distance a to the surface of a rotating cheese during the winding process.
