Definitions

  • thread may be evenly distributed along vthe surface thereof.
  • the thread usually is supplied at an angle substantially normal to the axis of rotation of the spool, passing first through a stationary thread guide or roller, next through a guide which is reciprocated by a conventional traversing mechanism and then onto the take-up spool.
  • This auxiliary thread guiding system comprises a roller which is rotatably attached to an arm, the arm being arranged laterally of the stationary thread guide and having one end pivoted about a fixed point and the other end pivotally connected to the traversing rod on which the traversing thread guide is mounted.
  • the roller is mounted on the arm exactly midway of the fixed pivot and the pivot which couples the arm to the traversing rod.
  • the length of the arm is of such a dimension that the distance between the running-off point of the stationary thread guide and the running-on point of the roller is equal to the distance between the running-off point of the roller and the running-on point of the traversing thread guide.
  • the traversing thread guide in this instance comprises a freely rotatable roller mounted on a cross arm of the traversing rod and a thread guide arm projecting from the rod and having a groove through which the thread passes.
  • One of the objects of this invention therefore is to provide a winding machine not having the inhertent disadvantages of known machines.
  • a further object of this invention is to provide an improved winding machine for winding a continuous thread into package form.
  • Another object of this invention is to provide a thread traversing mechanism for a winding machine which will distribute thread under uniform tension along the surface of the take-up spool.
  • Still another object of this invention is to provide a thread traversing mechanism for a winding machine which will maintain a constant length of thread travel between the stationary thread guide and the traversing thread guide at all times during the winding operation.
  • a floating linkage or auxiliary guide mechanism between the stationary thread guide and the traversing thread guide.
  • This linkage consists of two rigid arms, one of which is pivotally mounted to a stationary longitudinal beam and the other of which is pivotally mounted to the traversing rod, with the free ends of the arms being pivotally mounted one to the other.
  • the thread contacting surface of an auxiliary thread guide or eyelet is mounted so as to be coaxial therewith.
  • the linkage By providing arms having a total length greater than the distance between the stationary thread guide and the traversing guide when the latter is at the end of a stroke, as shown in the preferred embodiment, the linkage always remains in a broken or unstraightened condition and there is sufiicient linkage to accommodate the space between the stationary and traversing guides at any position. Inasmuch as the overall length of the two rigid arms remains constant, the path of thread travel defined thereby likewise never changes, which results in winding of thread under uniform conditions of tension.
  • the stationary thread guide consists of an eyelet having 'a thread contacting surface mounted coaxially with the stationary pivot point of said linkage and the conventional thread guiding roller
  • the traversing guide consists of an eyelet having a thread contacting surface mounted coaxially with the reciprocable pivot point of said linkage and the usual projecting thread guide which is provided with a thread contacting groove
  • the figure is a perspective view of a conventional winding machine embodying one illustration of applicants novel traversing mechanism and omitting certain drive means and apparatus not essential to an understanding of the present disclosure.
  • a preferred embodiment of a traversing mechanism is
  • each of the drive rollers 11 contacts and provides a surface drive for one of the plurality of take up spools 13, it being understood that for each of the spools there is provided a drive roller. Further discussion will be limited to a single winding station since each additional station is substantially a duplicate of the first.
  • the take-up spool 13 is clamped by conventional means (not shown) on shaft 14, which shaft is rotatably supported, in cantilever fashion, in bearing 15 of spool supporting lever 16.
  • the lever 16 is pivotally mounted on fulcrum 17 and is biased by spring 18 in a direction to resiliently urge the spool 13 into frictional contact with drive roller 11, whereby the latter, when driven, will impart rotation to the former.
  • An extension 20 of lever 16 serves as a handle whereby the spool may be swung outwardly away from drive roller 11 for dofiing purposes.
  • the spool moves about fulcrum 17 against the action of spring 18 as the winding of thread thereon proceeds.
  • the fulcrum 17 and spool 13 extend in a direction parallel with but spaced from the axis of shaft 12 in order that uniform surface contact will be established between the spool and roller in all positions of fill of the wound package.
  • a traversing rod 21 Above but closely adjacent to the main drive shaft 12, and parallel therewith, there is provided a traversing rod 21.
  • This traversing rod is slidably mounted in bearings (not shown) and is reciprocated longitudinally by any suitable means (also not shown).
  • a plurality of bars 22, one for each respective winding station discussed supra, are clamped about and therefore reciprocate with the traversing rod 21.
  • Each of these bars projects outwardly and downwardly from the traversing rod and tenninates in a struck up portion defining a thread guiding groove 23 which is positioned so as to overlie the takeup spool 13. It can be seen that as the bar 22 reciprocates longitudinally, thread passing through the groove 23 will be shifted laterally and distributed-uniformly over the surface of the spool.
  • a guiding eyelet 24 is positioned in alignment therewith and secured to the bar 22 by means 'of stem 25 and suitable retaining means, such as a threaded connection. and the groove 23 in bar 22 constitute and will frequently be referred to hereinafter as the traversing thread guide.
  • a longitudinal beam 26 which serves as a support for structure to be presently described.
  • a stub shaft 27 extends outwardly of beam 26 and rotatably supports a thread guide roller 28.
  • a cross arm 29 Also projecting outwardly from the beam at each winding station is a cross arm 29.
  • the stub shaft 27 and cross arm 29 may be secured to the beam by any appropriate means such as, for example, thread connections and/or welding, respectively, and the cross arm may provide additional support for the stub shaft, as shown in the drawing.
  • cross arm 29 functions as a stationary pivot for the linkage which constitutes the auxiliary thread guide of the present invention and which is identified generally by reference numeral 30.
  • a thread guide or eyelet 31 which is supported on the end of stem 32 and which, together with the guide roller 28, forms the stationary guide herein under discussion.
  • Upper arm 33 of applicants novel link-age is pivotally supported by the end of cross arm 29, as stated hereinabove, and lower arm 34 of this linkage is pivotally supported by bar 22 of the traversing thread guide unit.
  • the free ends of inflexible arms 33 and 34 are pivotally secured one to the other by a pin 35, the outer end of which is shaped to form a third or auxiliary thread eyelet 36.
  • each pivot point of the linkage 30 is coaxialwith the thread guiding or contact- The eyelet 24 ing surface of a respective thread eyelet or guide.
  • extensions of the thread eyelets may constitute the pivots.
  • the length of arms 33 and 34 has been chosen so as always to exceed the distance between the stationary guide structure and the traversing guide, in any position of the latter.
  • the group of threads 37 to be wound into individual package form is fed at a uniform speed from a supply source (not shown) by feed rolers 38 which are driven at a uniform velocity by conventional means (also not shown).
  • feed rolers 38 which are driven at a uniform velocity by conventional means (also not shown).
  • Each thread 39 emerging flom the feed rollers is directed over a respective guide roller 28, through a relatively stationary guide eyelet 31, auxiliary guide eyelet 36, the traversing thread guide, which comprises eyelet 24 and groove 23, and onto the take-up spool 13.
  • the above described traversal mechanism may be used in conjunction with any type winding machine which receives threads continuously from a supply source, such as a slasher or a continuous spinning machine wherein a plurality of threads are spun, united to form a series of parallel threads moving at a slight mutual distance in a plane having a rectilinear cross section and thereafter led through a number of aftertreating baths and finally dried.
  • a supply source such as a slasher or a continuous spinning machine wherein a plurality of threads are spun, united to form a series of parallel threads moving at a slight mutual distance in a plane having a rectilinear cross section and thereafter led through a number of aftertreating baths and finally dried.
  • auxiliary guide linkage 30 With respect to the overall length of applicants auxiliary guide linkage 30, it is pointed out that the same need not necessarily exceed the maximum distance between the stationary and traversing guides although it is obvious that this length must always at least equal this distance, since it is propsed that the arms 33 and 34 be constructed from non-elastic material. In other words, the toggle 33, 34 could straighten in the extreme portions of the traversing stroke, if desired. In order to simplify fabrication of applicants mechanism, however, it is preferred that the total length of the linkage 30 always exceed the maximum distance between the stationary and traversing guides.
  • the linkage 30 be mounted only at the first and last of these stations and that a third or connecting arm extend parallel with the traversing rod 21 and be pivotally attached at one end to the pin 35 of the first linkage 30 .and at the opposite end to the pin 35 of the last linkage 30.
  • Auxiliary guide eyelets or rollers may then be mounted at suitable positions along the length of this third arm, which positions should correspond to respective intermediate winding stations.
  • a machine for winding a continuous thread into package form comprising a take-up spool, a traversing thread guide mounted for movement adjacent to and along the surface of said spool, a stationary thread guide for guiding thread from a supply source to said traversing thread guide, and an auxiliary thread guiding mechanism for maintaining the length of thread extending between the traversing and stationary thread guides constant throughout the traverse stroke, said mechanism including a linkage pivotally attached at one end to said traversing thread guide for movement therewith and pivotally attached at the other end to said stationary thread guide, said pivotal connections being coaxial with thread contacting surfaces of said traversing and stationary thread guides, respectively.
  • said linkage comprises an upper arm and a lower arm, the adjoining ends of which are pivotally connected, and a thread guide having a thread contacting surface mounted coaxial with the pivotal connection between adjoining ends of said upper and lower arm.
  • a machine for winding a plurality of continuous threads into individual pack-age form comprising a plurality of take-up spools axially aligned in spaced relationship, a plurality of traversing thread guides each of which is mounted for movement adjacent to and along the surface of a respective take-up spool, a plurality of aligned stationary thread guides each of which guides a thread from a supply source to one of said traversing thread guides, and a plurality of auxiliary thread guiding mechanisms, one for each of said traversing guides, for maintaining the length of thread extending between respective traversing and stationary thread guides constant throughout the traverse stroke, each of said mechanisms including a linkage pivotally attached at one end to said traversing thread guide for movement therewith and pivotally attached at the end to said stationary thread guide, said pivotal connections being coaxial with thread contacting surfaces of said traversing and stationary thread guides, respectively.
