Definitions

  • the present invention relates to an apparatus for winding continuous thread onto a reel which rotates through being driven by contact with a friction roller.
  • the reel rotates in a fixed position while, as the winding progresses, the roller is displaced, being for example mounted on an oscillating arm or on a carriage.
  • the friction roller rotates in a fixed position while the reel is mounted on a carriage or on an arm adapted to rotate about an axis in such a way that the reel is moved away from the roller as the winding increases.
  • roller and reel may be maintained at a constant level very easily, just as it is relatively simple to vary the pressure according to a preestablished law during winding of the reel.
  • the movable element can rotate about a fixed axis, the solution of the problem is rather more difficult.
  • the present invention relates to those apparatus in which winding of the continuous thread is carried out by contact between a roller and a wheel, when one of these two elements is mounted on an arm rotating about its axis.
  • the tension of the thread is maintained constant during winding by an arrangement adapted to regulate the contact force between the roller and the reel, such regulation taking place as a function of the diameter of the reel while it is being wound, the-formation of a desirably regular reel being at the same time achieved under constant conditions of operation.
  • an apparatus of the present invention comprises:
  • the said contact force may be regulated by an arrangement which consists in applying to the reel-holding arm a balancing force contrasting with that due to the weight of the reel being formed and the weight of the relative arm, the said force being maintained constant for the time involved and, during the winding, generating moments in respect of the fulcrum of the reel-holding arm, which are variable according to a pre-determined law.
  • the moment generated by the thrust of the friction roller on the reel depends at all times both upon the moments generated by the weight of the reelholdinj arm and the reel being formed, and that generated by the balancing force which is applied.
  • the apparatus may be essentially described as that in which the force of contact between the roller and the reel is controlled by, over the time involved, varying the balancing force applied at the arm, the said force generating in respect of the fulcrum of the reelholding arm moments which are variable over the time according to the diameter of the reel being formed.
  • the reel-carrying arm is connected to a counter-weight or spring by means of an extending element which is wound on a cam pivoted on the reelholding arm, and during the thread-winding operations, the said cam is caused to rotate to considerably greater amplitude compared with the corresponding angular displacement of the arm, this effect of amplification being obtained by the use of epicyclic gears.
  • FIG. 1 is schematic view of one form of the thread winding device according to the present invention when the diameter of the reeled thread is relatively small.
  • FIG. 2 is a view similar to FIG. 1 with the diameter of the reeled thread being substantially larger.
  • FIG. 3 is a view similar to FIG. 1 showing a modified form of the thread winding device according to the present invention.
  • the cam 4 is required to complete about its own axis a rotation of much greater amplitude in respect of the rotation of the arm in order to compensate for the greatly variable imbalances which occur during winding of the reel.
  • this result may be achieved by the use of epicyclic gears which, in their simplest version (FIG. 3), consist of a satellite wheel 7A coaxial with the cam 4 and connected rigidly therewith, and a fixed toothed segment 8A coaxial with the fulcrum of the reel-holding arm.
  • the gearwheel mechanism may be replaced by an equivalent solution such as that indicated in FIG. 1, consisting of a smooth wheel 7 coaxial with the cam 4 on pivot 11 and connected by a non-extensible strip 9 to the segment 8 coaxial with the fulcrum of the reel-holding arm.
  • FIGS. 1 and 2 show the winding device in empty and full conditions, respectively, of the reel 2.
  • the reel-carrying arm 3 is pivoted at 10 on a fixed bed M and extends obliquely upwardly towards the driving roll 1 rotatable on a fixed axis la so that a contact force S arises between the roller 1 and reel 2 due to the moments of the arm weight P and reel weight P about the pivot 10.
  • S is the force by which the reel abuts against the driving roller 1.
  • the moment Z is a product of a constant force O (which is the weight of the counterweight 5) by a moment arm e.
  • the counterweight 5 is attached at one end of a tape 6, the other end of which is wound on a cam 4 and riveted to the latter at 6";
  • the moment arm e is the distance between the run 6' of the tape 6 and a linefconducted through the pivot in direction parallel to 6'.
  • the cam 4 is fast with a pulley 7 rotatable on a pin 11 carried by the arm 3.
  • the pulley 7 represents a planetary gear in an epicyclic gearing including a circular segment 8 fixed to the bed M concentrically to the pivot 10.
  • a tape 9 has its ends wound about the pulley 7 and segment 8 and riveted thereto at 9', 9", respectively. In this manner the pulley 7 meshes with the segment 8, the latter representing a sun wheel in the epicyclic gearing.
  • the pulley is shown as a toothed gear 7A and the segment as a toothed segment 8A.
  • the gear 7A rolls on the segment 8A in the direction of the arrow.
  • the angular displacement of the wheel 7A about its pin 11 depends upon the ratio of the radii of the wheel and segment.
  • the gear .7A turns through 120, as does the cam 4.
  • the moment arms 6 and d decrease because of the clockwise displacement of the arm 3.
  • the pull applied by the counterweight 5 to the tape 6 causes the cam 4 to rotate clockwise.
  • the second tape 9 winds on the pulley 7 while unwinding from the segment 8 and controls in this manner the angular displacement of the pulley 7 just as the angular displacement of gear 7A in FIG. 3 is controlled by the mesh of the gear with the toothed segment 8A.
  • the angular displacement of the cam 4 is at any moment a multiple of the angular displacement of the arm 3 and this fact permits to design the profile of the cam according to the requirements.
  • R is the radius of the sung gear (segment 8) and r is the radius of the planet gear (pulley 7). It will be seen that when the two radii are equal, the amplifying factor is 2. When r is 1 (one) and R is 4, the amplifying factor is 5; this means that a rotation of arm 3 through 18 produces an 18 X 5 90 rotation of the cam 4.
  • the ratio between rotation of the cam and rotation of the reel-holding arm depends upon the radii of the wheel 7 and the segment 8, and these values are selected in such a way as to satisfy the afore-defined conditions.
  • the force with which the reel is driven by the friction roller can be made to vary according to a desired pattern and preferably it is maintained constant during the winding.
  • cam having a plurality of radially adjustable segments in order to facilitate those adjustments which are required under various conditions of working, such as for example when the apparatus has to be used for successive windings of threads of different specific weights.
  • the apparatus of the present invention furthermore makes it possible to obtain regular reels even of large diameter, and in particular it is possible to obtain reels of a diameter up to 600 mm while still operating under reliable conditions. Finally, the apparatus is sufficiently flexible that it can be rapidly adapted to the varying conditions which arise in practical working.
  • An apparatus for the winding of continuous thread comprising:
  • cam means rotatably mounted on said arm intermediate the end thereof;
  • said means for varying the counter balancing force comprising a wheel coaxial with and connected to said cam means for rotayion therewith about the axis thereof, a stationary circular segment coaxial with the pivot axis of said arm and means connected between said wheel and said segment for rotating said wheel through an angular displacement of considerably greater amplitude than the corresponding angular displacement of the reel holding arm about the pivot axis thereof.
