Definitions

  • a winding apparatus for newly formed strands of thermoplastic material, constituted by filaments issuing from a plurality of spinning nozzles of a spinneret containing said material in liquid form, such as molten glass, disposed below the latter.
  • Two winding drums ,on fixed axes extend in parallel to each other in a plane inclined to the horizontal, onto which are adapted to be mounted empty spools, and with which cooperate strand traverse mechanisms which serve to lay up the strands on the spools in crossing relation while the rotary movement of the latter effects a drawing-out of the filaments.
  • the specific disposition of the winding drums permits a convenient transfer of the strands issuing from the spinneret, from the filled bobbins on one drum to the empty bobbins on the other drum without interrupting the drawing-out of the filaments.
  • This transfer may be executed in a non-automatic, semi-automatic, or fully automatic manner.
  • the completion of a predetermined number of revolutions of the active winding drum automatically positions an auxiliary rotary winding cage onto the end of the last-mentioned drum by means of a pivotal movement followed by an axial movement of the cage.
  • a deflecting bar shifts the strands from the bobbins being wound on the winding drum onto the winding cage whereat the drawing out of the filaments continues.
  • the rotary cage 18 then moved axially from the end of the active winding drum, rotated into coaxial position with the heretofore idle winding drum and axially shifted onto the end thereof, without any interruption of the drawing out of the filaments.
  • the last-mentioned drum reaches second drum.
  • the invention relates to the production of threads or strands of thermoplastic material, particularly glass threads formed by groups of filaments issuing from the orifices of a spinneret which are drawn-out by winding on rotary bobbins.
  • the elementary or primary newly formed filaments are gathered in a unitary strand are are wound on the bobbin which efiects their attenuation or drawing-out.
  • several turns are formed by hand on the edge of the winding drum at the time the winding cylinder is put in motion, and it is only when the winding cylinder has attained the necessary speed, and when the threadguide has been set in motion, that the thread is passed into the thread-guide and wound on the sleeve.
  • a device for the continuous successive winding of a strand or bundle of fibers, in particular of thermoplastic material, on two or more rotating bobbins arranged on a turntable, with the full bobbin being displaced from the winding position and the empty spool being placed in the path of the strand or bundle of fibers.
  • Such an arrangement is disclosed in German Pat. No. 546,162.
  • This known device presents very complex inconveniences, because the winding cylinders are mounted on a turntable and are arranged for rotary movement, which gives rise to several problems. Besides, it is very difficult to make the rotating turntable water-tight and dust-proof with respect to the framework of the machine, the soiling thus produced inside the framework causing other difficulties.
  • This apparatus also requires a great deal of space, in particular when it is necessary to work with winding drums 250 mm. in diameter. This space is not always available in a direct fusion installation, if it is not intended to increase the separation of the spinning nozzles, which would lead to operational difficulties of the front crucibles containing the spinnerets, which in turn would lead to difficulties in regard to the production of the strands.
  • the apparatus comprises two winding drums or cylinders, the axes of which are horizontal and parallel to each other and disposed in a common plane at an inclination to the horizontal. It is thus possible, when the sleeves mounted on one of the winding drums becomes full, to pass the thread immediately by hand onto the empty sleeves on the other winding drum. The removal of the full bobbins from the first winding drum and the charging of the latter with empty sleeves is accomplished during the winding of' the sleeves on the second winding drum. In this way about 50 percent of the time for changing is saved, (formerly 47 seconds, presently 17 seconds); and the amount of waste is reduced to a minimum.
  • the axes of the parallel winding drums are disposed in a plane having an inclination of angle a with respect to the horizontal.
  • This inclination may vary from 30 to 60, and preferably is 45. If the angle of inclination a is too small or too large, it is necessary to select a wide separation between the two winding drums so that the replacement of the full spools by the empty ones can take place without difficulty and without disturbing the travel of the strand during the winding of the sleeves'on the other winding drum.
  • Such an arrangement therefore requires a lot of space and cannot be adopted in the case of a direct fusion installation.
  • one of the winding cylinders is at a height which makes difficult the replacement of a full spool by an empty one.
  • the adoption of a 45 angle of inclination permits the arrangement of the two winding cylinders as close together as possible along a horizontal projection, while reducing to a minimum the required space, which is of particular importance in the production of glass filaments in a direct fusion installation.
  • FIG. 1 Another advantageous characteristic of the apparatus in accordance with the invention results from a horizontal and verticalseparation between the winding drums or cylinders of preferably about 318 mm.
  • the winder can still be placed in the direct fusion installation, even if the diameterof the winding drums is 300 mm.
  • Such a separation or spacing also permits the operator to replace the full spools with empty ones without difficulty, and without disturbing the winding operation.
  • a special feature of the invention concerns an apparatus which makes possible the transferof the winding operation from one winding cylinder onto the other entirely automatically.
  • An apparatus as disclosed in US. Pat. No. 3,231,207, Jan. 25, 1966 contemplates winding a strand or bundle of primary fine filaments derived from a stream feeder of heat-softened material, such as molten glass.
  • a stream feeder of heat-softened material such as molten glass.
  • an empty bobbin is set in rotation after being put in place, and the winding of the strand of filaments is primed near the marginal zone of the empty bobbin, the strand being then wound over the winding zone of the bobbin.
  • a guide rod is posi-' tioned parallel to the axis of the bobbin and is axially movable to automatically push off the strand in the axial direction of the bobbin at the end of the winding by separating it from the full bobbin and beyond the strand traverse guide.
  • the strand is maintained in separated position from the winding zone during the changing of bobbins and is brought back to the winding zone of the empty bobbin as soon as the latter has been put in place and has reached its normal rotary speed.
  • a proposed device for executing this mode of operation comprises an auxiliary member ran in the above device, havin an auxilia member constituted by a winding crown or cage, fitted with fingers and capable of being set in rotation, upon which the strand is deflected as soon as the spool is full, and which is wound until it is transferred to a new empty sleeve or spool, and a deflectingdevice for the strand, making it pass from the full spool onto the auxiliary member and from the auxiliary member to the empty sleeve, in such a way that the work can be assured with a winding apparatus having two rotary winding cylinders with fixed axes disposed in an inclined plane.
  • the desired objectives of the invention are attained by providing the winding cage with a pivoting arm as well as with means to displace the winding cage in the axial direction of the winding cylinders, and also with means to make the winding cage pivot from the axis of one of the winding cylinders into the axis of the other winding cylinder.
  • the simplification arising from the invention may be attributed in part to the mobile arrangement of the winding crown or cage, so that its fingers may move along the axis of the winding cylinders and also surround their extremities.
  • the passage of the strand from the full sleeve onto the fingers of the winding cage, as well as the passage of the strand from the fingers onto the new empty sleeve is effected by means of a deflecting member.
  • an advantageous arrangement of the deflecting device comprises a deflecting bar adapted to deflect the strands beyond the winding zone on one winding drum following the completion of the winding of the spools on the latter, and to guide the strands onto the fingers of the coiling cage, which is followed by the conveyance of the strands from the fingers onto the empty spools of the winding drum; a guide cylinder adapted to guide the deflection bar; and a double acting pneumatic jack adapted to displace the deflecting bar from the starting position to the operating position and return.
  • this simple arrangement of the deflecting device makes possible a weak deflection of the two strands simultaneously and the transfer of these strands onto the fingers of the rolling crown or cage, as well as the presentation of the strands from the fingers of the rolling crown onto the empty sleeves of the other winding drum.
  • the guiding may be executed by means of a deflecting bar shaped as a fork.
