Definitions

  • the invention relates to a device for winding threads according to the preamble of patent claim 1.
  • Wing traversing devices are particularly suitable for use at high traversing frequencies.
  • the alternating movement of the thread is not brought about by a single thread guide moved to and fro, but by the fact that wings rotating in opposite directions alternately grasp and guide the thread. Since the wings at the end points of the traversing area are neither accelerated nor decelerated, the influence of the inertial mass of the thread guide members is completely eliminated when the thread is reversed.
  • the oppositely moving blades of the two rotors meet at certain fixed meeting points.
  • the meeting points are evenly spaced on the turning circle.
  • the angular distance depends on the number of blades on a rotor. For example, if a rotor has two blades, it is 90 degrees. The change takes place between two neighboring meeting points.
  • the wing which is located in the area of this quarter-circle arc, guides the thread. When it reaches the meeting point, it hands it over to the oncoming wing of the other rotor. After this has covered an angle of exactly 90 degrees, the thread is taken over by the second wing of the first rotor, etc.
  • an exact thread transfer at the end points of the traversing area is of the greatest Meaning.
  • the two rotors of the wing traversing device are arranged offset from one another in such a way that the axis of the one rotor in the direction of the traversing stroke, i.e. parallel to the coil axis. This facilitates the transfer of the thread from one wing of one rotor to an oncoming wing of the other rotor.
  • the take-over wing protrudes from the turning circle of the emitting wing. The protruding wing end takes over the thread that slides from the wing tip of the releasing wing (DE-OS 33 07 915).
  • a winding machine in which the two rotors are arranged coaxially is also known from EP-A1-0 322 752.
  • additional guide elements are provided which favor the exact thread transfer at the ends of the traversing area.
  • the traversing device is often inclined so that there is an acute angle between the planes of rotation of the wings and a tapering thread.
  • the inclined position ensures that the thread length between the traversing wings and the guide roller arranged behind them can be kept very small. This measure is essential for exact thread guidance.
  • the turning circle of the vanes which revolve in the rotating plane further away from the guide roller, protrudes a little beyond the turning circle of the vanes of the other rotor.
  • this wing comes into contact with the thread a little too early. At the other end, he releases the thread a little late.
  • the invention has for its object to improve a device according to the preamble of claim 1 so that the wing constellation and the movements at the two end points of the traversing area are matched to each other.
  • the axes of rotation of the two rotors are arranged in such a way that exactly at the point in time at which the wings have reached the angular position corresponding to the end of the traversing stroke, the releasing wing is submerged behind the thread running surface and the receiving wing emerges from this surface.
  • a coil structure which is equally good on both ends of the coil is achieved.
  • the axes of the two rotors are preferably also offset in the direction parallel to the axis of the guide roller, in order to ensure reliable thread transfer without additional guide elements in a known manner.
  • a winding spindle 1 and a guide roller 2 are connected to a machine frame in a known manner.
  • a traversing device 3 is also attached to the machine frame, not shown, by means of a holding plate 4, which is only indicated.
  • the traversing device 3 is assigned a guide ruler 5 for the thread 6 tapering vertically from above.
  • the holding plate 4 carries an eccentric bushing 7.
  • a rotor 8 is mounted on its outer surface, consisting essentially of an annular base body 9, a ring gear 10 which sits on the base body 9, and two propeller-like wings 11, 12.
  • the eccentric bushing 7 has a hole whose axis is shifted parallel to the axis of the lateral surface. The distance between the two axes is the eccentricity e (Fig. 2).
  • the shaft 13 of the other rotor 14 is mounted in the bore. One end of the shaft 13 protrudes beyond the plane in which the vanes 11, 12 are arranged. At this end two propeller-like blades 15, 16 are attached, which are essentially mirror-inverted to the blades 11, 12.
  • On the other end of the shaft 13 there is a toothed pulley 17.
  • the toothed ring 10 and the toothed pulley 17 can be driven by toothed belts, not shown. They are coupled by a gear in such a way that they rotate in opposite directions at the same speed.
  • the traversing device 3 is inclined so that the thread running surface, which is slightly curved as a result of the curvature of the guide ruler 5 shown in FIG. 2, encloses an acute angle ⁇ with the two planes of rotation at the end points of the traversing region, which is generally between 40 and 75 ° , in the illustrated embodiment is between 50 and 60 °.
  • the axis of the rotor 14 is to the axis of the rotor 8 in the direction of the guide ruler 5, i.e. in the direction parallel to the axis 2 'of the guide roller 2, offset by the piece b and at right angles to the piece a. This gives the eccentricity e.
  • the offset a has the effect that, in FIG. 3, which shows a snapshot of the device at the moment the thread is transferred, the tips of both wings 12, 16 seem to just touch the thread running surface, which is illustrated in FIG. 3 by the same line as the thread 6
  • One wing, for example 16 is currently immersed behind the thread running surface.
  • the other wing, in this case 12 emerges simultaneously from the thread running surface and takes over the thread guidance.
  • the wing 12 covers exactly 90 °, starting from the point in time at which it takes over the thread up to the point in time at which the wing 15 offset by 180 ° from the wing 16 takes over the thread.
  • the offset b is independent of the inclination and is only used in the usual way to facilitate thread transfer.
  • the exemplary embodiment illustrated in FIG. 4 differs from the previously described exemplary embodiment essentially in that the guide ruler 5 is arranged between the rotational planes of the two pairs of rotor blades on the one hand and the guide roller 2 on the other hand. Therefore, the turning circles of the wing pairs 11, 12; 15, 16 that part of the thread running surface lying between a stationary thread guide eyelet 20 and the guide ruler 5.
