Definitions

  • the invention is concerned with traversing for bobbins, preferably for winding filament threads, that is to say bobbins, which are designed to form cross-wound bobbins from threads, preferably with delivery speeds greater than 2000 m / min. are delivered, the delivery speed at most above 7000 m / min. lies.
  • Traverses for use in filament spinning are usually based on one or the other of only two basic constructions, namely the grooved drum and the wing traversing (see EP-A-622 324, according to which these two types should fit selectively in a given machine cross section).
  • the working principles of these two constructions are limited in their further development possibilities.
  • the limitation for the grooved drum lies in the maximum traversing speed and for the wing traversing in the flexibility of the thread placement over the stroke.
  • the positioning of the thread during feed and bobbin change must be implemented with the aid of other mechanical means (e.g. lifting plate, sliding plate).
  • the invention provides a traverse for a winder, preferably for winding filament threads, which is provided with at least one movable carrier carrier, on which at least one the thread travels over a traverse stroke leading driver is located, the driver is slidably mounted on the carrier carrier.
  • the driver can be moved at least between a transport position and a takeover position. A rest position is also to be inserted if drivers pass through the stroke area without being allowed to take over the thread.
  • the carrier carrier is preferably mounted rotatably about a predetermined axis of rotation.
  • the driver can be displaceable in radial directions relative to the driver carrier.
  • the displacement can originate from a pulse generator, which can be arranged in the vicinity of the axis of rotation, wherein means for transmitting the displacement to the driver can be provided at a location remote from the axis of rotation.
  • the pulse generator preferably works without contact, for example by means of an (electro) magnetic field or a compressed air pulse. In principle, however, it can also be designed as a mechanical backdrop. Furthermore, combinations of the types mentioned are possible which optimally enable the triggering or resetting.
  • the carrier carrier can have at least one arm which extends in a radial direction away from the axis of rotation.
  • the driver is then preferably slidably mounted on the end of the arm remote from the axis of rotation.
  • a carrier carrier is preferably provided with a plurality of carriers.
  • the carrier carrier can therefore have several arms, each provided with at least one carrier.
  • the carrier carrier could also be designed as a disc, with several carriers distributed along the periphery of the disc being mounted in the edge zone of the disc.
  • the carrier carrier is designed as a belt, which (as in a classic belt rotation) follows a predetermined endless path moved along.
  • the driver can be moved or swiveled transversely to the path.
  • the traversing can also comprise a guiding ruler, the thread being moved back and forth on the guiding ruler during traversing.
  • Fig. 1 shows a version of the new traversing, shown in perspective
  • Fig. 2 shows a rotor as a carrier carrier for use in a traverse according to Fig. 1, with movable carriers
  • FIG. 3 shows a detail of a carrier carrier with a displaceable carrier according to FIG. 2 in its thread take-over position

  • Carrier carriers within a winding head shown semi-schematically
  • Fig. 12.1 seen three carrier carriers arranged side by side according to Fig. 1 and further in the direction (I Fig. 11)
  • a traversing mechanism according to the invention is preferably designed for use in a high-speed gun, for example according to EP-A-749 929.
  • a high-speed gun for example according to EP-A-749 929.
  • such machines had to be constructed to form a predetermined type of coil, preferably for cylindrical cross-wound bobbins with a predetermined axial stroke length and with end faces perpendicular to the axis of rotation (also called “cheese” in English).
  • This form of coil or package has been explained in the aforementioned EP document. If the machine was now to be used to form a cylindrical packing with a different stroke length, the traversing had to be replaced up to now. The formation of a different package geometry (for example a biconical coil with bevelled end faces) is practically impossible for such a machine.
  • each drive unit 14 or 16 forms an axis of rotation (not indicated) for the corresponding rotor 10 or 12.
  • the axes of rotation D of the counter-rotating carrier are preferably on the same line, so that it can be ensured that the reversal can take place at any point of the stroke under the same conditions.
  • the fact that the axes of rotation are not on the same line, which is necessary, for example, for wing transfer for the transfer of the thread, is replaced by the two different positions, namely the transfer position (Uep) and the transport position (Trp) in FIGS. 3 and 4 ( Fig. 10).
  • the drive units 14 and 16 can drive a plurality of rotors in one direction of movement, which are then connected to one another, for example, by a gear.
  • the lower rotor 12 can then be driven by a drive unit 16, which is located on a Neighboring location above the rotor 10 is located.
  • This system is preferably arranged above the contact roller (KR) as shown in FIG. 11, or if the flexibility regarding the stroke width is not desired, the drive can also be reduced to a single one, the rotors then being linked via a gear.
  • the rotors 10 and 12 are shown as disks in FIGS. 1 and 2.
  • the discs can be reduced to at least one-armed carrier carriers.
  • a three-armed rotor is shown in FIG. 6, for example. 2 shows the rotor 10 as an example, the rotor 12 being practically identical, so that FIG. 2 actually applies to both rotors and a special description of the rotor 12 can be dispensed with.

  • the outer end of each rod 24, 26, 28 is located in an edge zone of the disc 10, while the inner end is in the vicinity of the axis of rotation D.
  • Guides 30, 31, 32, 33 and 34, 35 attached to the surface 22 prevent transverse displacements of the respective rods 24, 26, 28, but allow the rods to perform limited displacement movements (VR) in radial directions.
  • Each rod thus makes the rotary movement TrR of the carrier carrier, but is at the same time relative to the carrier carrier at least between a transport position Trp (also called transport position Trp) and a take-over position Uep (also called take-over position Uep), the rods 24 and 26 in FIGS. 2 and 4 being shown in their transport position Trp and the rod 28 in FIGS. 2 and 3 being shown in their take-over position Uep.
  • Figures 3 and 4 show the rod 28 (as an example) on a larger scale, the central part of the rod being cut away, since it plays no role in the main function to be described.

  • the outer end of the rod forms a thread guide 36, as will be explained below with reference to FIG. 3.
  • the inner end 38 is provided, for example, with a permanent magnet which is fastened to the rod 28. This permanent magnet works together with two permanent magnets or a switchable electromagnet, which are attached to the frame 20.
  • the permanent magnets 40 and 42 as well as a possible electromagnet are provided in a ring shape with a U-shaped cross section, the permanent magnet on the rod 28 being in the U cross section depending on the polarity of the legs of the U-shaped cross section to the right, with a view of the Figure is seen or moved to the left.
  • the ring When using a permanent magnet in the aforementioned annular type with a U-cross section, the ring is divided into segments (see also FIG. 9) which have different polarities, as is the case with the identifiers 40 and 42 and the letter N therein for the north pole or S for the South Pole is shown.
  • FIG. 9 An example of a division of the circle segments from the permanent magnets 40 and 42 is shown in FIG. 9. The same elements of FIGS. 3 and 4 and 5 are shown therein on a smaller scale, but with the same reference numerals.
  • the inner ring of the magnet 40 exerts a repelling force on the magnet 38 and the outer ring exerts an attractive force, which pushes the rod 28 radially outward relative to the rotor 10 until a shoulder part (not shown) on the rod against one Stop (not specifically indicated).
  • the thread-guiding end part 36.2 of the rod is able to take over the thread from the oppositely rotating driver 36.1 located in the transport position Trp and to take it along in the direction corresponding to its rotational movement, which is illustrated in FIG. 10.
  • the offset is not achieved by the eccentricity of the rotors 10 and 12, but is exclusively due to the 2 positions, i.e. takeover and transport position.
  • the inner ring of the magnet 42 exerts an attractive force on the magnet 38 and the outer ring exerts a repulsive force, which pulls the rod 28 radially inward again until the end of the rod abuts against a stop 44 fastened on the rotor 10 and is thus in the transport position Trp.

Viewed in plan view (Fig. 5), the disc edges are 11 and 13 (edge of the disk 12, see FIG. 1) directly below the end face 19 of the cover 18, which forms a guide for a thread 46.

  • the traversing speed of the thread F is largely determined by the rotational speed of the rotors 10, 12 and the guideline geometry.

Since the function is otherwise the same, no further description is given.

  • FIGS. 5 and 9 or B1, FIG. 7 show the maximum stroke length for each variant (HB, FIGS. 5 and 9 or B1, FIG. 7).
  • the great advantage of the variants listed here is that the maximum length does not have to be fully utilized, since the thread takeover can also be triggered at intermediate points within the maximum possible stroke.
  • This can be achieved by applying a plurality of drivers to the driver carrier, which optionally come into action in a controlled manner, and / or by accelerating the belt or the rotor, the drivers of which do not transport a thread and are in the rest or transport position, which is at least a single drive which requires the carrier carrier to move in the opposite direction. This enables stroke breathing or stroke shortening to be achieved.
  • This ability can also be used to guide the thread outside of the traversing stroke intended for it, for example during a bobbin change according to EP-A-703 179.
