Definitions

  • a beam-warper creel device having respective thread guide means vertically and horizontally spaced from one another in a sequence of vertical rows and horizontal levels, is provided with a thread holding apparatus for transferring the thread from the guide means to a warper.
  • the holding apparatus comprises a structure for holding the threads coming from said thread guide means, which structure is perambulatory horizontally along the sequence of vertical rows.
  • Eye bars are connected with the holder structure to travel together therewith and are correlated to respectively dilferent horizontal levels of the said thread guide means.
  • Each of the eye bars has a number of eyes through which respective threads from different ones of the vertical rows are to be threaded.
  • the eyes of each bar are serially displaceable along the bar for individually threading one thread from each level of one of the respective rows.
  • My invention relates to a device for passing the threads from a warper creel to a beam warper machine with the aid of one or more thread holders in which the threads coming from the supply coils of the creel are held and which together with the attached threads, are to be transferred from the creel assembly to the beam warper.
  • Warper creels in which several or many vertical rows of thread packages or coils are arranged horizontally behind one another require that the threads passing from the creel to the warper be deflected by guide means from their travel direction in order to prevent the threads from rearward rows to become entangled with threads from preceding rows.
  • the creel equipment is provided with thread-path changing guide means located at the front side facing the warper machine and comprising an individual thread guide for each of the threads travelling from the creel to the warper.
  • Various pathdirection changing guide means are known for such purposes.
  • the direction changing thread-guide means regardless of their particular type or construction, are hereinafter designated as eye bars or eyes.
  • the yarn holder means are indirectly or directly connected with eye bars which are displaceable alongside the creel and whose individual eyes, each having a thread opening or gap, are shiftable on the eye bars in such a manner that the threads passing from the creel to the yarn holder and appertaining to the respective horizontal levels of the vertical coil rows are individually and sequentially engageable by the eyes of the appertaining eye bars.
  • the term eye is understood to refer to any means capable of guiding an individual thread. Consequently, the term includes not only correspondingly curved hooks, curlicues (pigtail hooks) or the like, but for example, also screw-thread spindles which are covered by a bar and into whose individual screw turns the threads are placed; the term eye may also refer to notched bars in which the threads are guided by means of a lifting bar to pass from one notch to the next.
  • the shifting of the threads on the eye bars may be effected, if desired, by revolving the threaded spindle in the desired sense.
  • the eye bars coordinated preferably to the individual levels of the creel coil arrangement can be displaceable along the creel either individually or con jointly.
  • the eye bars are preferably mounted on a frame structure.
  • the yarn holders for trans ferring the threads on the creel to the warper are connected with the eye bars, either directly or by being attached to the frame or the wheeled carriage structure on which the bars or the frame are supported.
  • the eyes are constituted by covered screw spindles, these spindles have one turn freely exposed at the end closest to the creel.
  • the thread is taken up by this exposed turn and is then shifted under the covering bar as the spindle is being turned.
  • the eyes consist of the conventional hook-shaped structures, it is preferable to facilitate threading of the threads into the respective eyes by guiding the eyes on the eye bar along a path so shaped that the eyes change their travel direction at the locality closest to the creel.
  • the travel path of the eyes may be U-shaped or V-shaped, for example, and may extend in a horizontal, vertical or slanting plane.
  • the path of the eyes is arranged in a vertical plane and extends aong the top side and the bottom side of the eye bar, passing around the front end of the bar that faces the creel.
  • the eyes are guided around the front end as they pass from the bottom to the top or conversely from top to bottom of the eye bar, and during such change in direction the hook-shaped eyed catch with their threading gaps over the individual threads then situated at that locality.
  • the eye bar with a contour which guides the threads in front of the threading gap of the hook-shaped eyes at the locality where the eyes change their travelling direction as described above.
  • FIG. 1 is a perspective view of part of the warpercreel device
  • FIG. 2 is a partly sectional and perspective view on larger scale of an eye bar which forms part of the equipment shown in FIG. 1 and constitutes essentially the end portion of one of the eye bars at the locality directed toward the creel;
  • FIG. 3 is a schematic and partly sectional view of a device for moving the eyes along the guide path of the eye bars in dependence upon longitudinal movement of the eye bars along the creel;
  • FIG. 4 shows a detail of FIG. 3 along the section line IVIV indicated in FIG. 3.
  • FIG. 1 there is shown a vertical standard 1 which forms part of the outer frame of the creel structure on which an array of creel coils are arranged, preferably on an inner frame, in the conventional manner. Details of the creel structure and the arrangement of coils are not illustrated. If desired, reference as to these features may be had, for example, to the above-mentioned U.S. Pats. No. 3,317,979, No. 3,377,677 and No. 3,415,- 463.
  • the threads coming from the respective supply coils of the creel are passed through thread tensioners and thread-guide eye means 2 in the conventional manner and subsequently the threads from each vertical row are twisted or knotted together at the localities denoted by 3. Up to this point the insertion of the threads may be effected by hand or by automatic means such as described, for example, in U.S. Pat. No. 3,317,979. For transferring the threads from the warper creel to the warper machine (not illustrated) the threads are placed into thread holders 4.
  • the thread holder 4 is fastened by means of a manually operable screw 8 to a wheeled frame structure 7 which is displaceable along fixedly mounted rails and 6.
  • the manually operable screw 8 perrnits loosening the holder 4 from the wheeled frame structure 7, a handle 4a being provided at the free end of holder 4 to facilitate manipulating or carrying the holder.
  • Each eye bar 9 is fastened to the travelling frame 7.
  • Each eye bar carries a number of eyes 10 which are displaceable along the bar.
  • the particular eyes 10 in the illustrated embodiment are hook-shaped and are guided along a path which extends along the top 9a and the bottom 9b of the eye bar 9. During travel, therefore, the eyes pass around the front end of the eye bar facing the creel.
  • An endless transport chain 11 serves to move the eyes 10. The chain 11 is guided between the lateral walls of the eye bars. Its links carry the respective eyes 10.
  • the eye bar has a particular contour 9d which guides the thread in front of the threading gap 10a of the one eye 10 that is to receive the thread.
  • the threading gap 10a is covered by a correspondingly shaped portion of the side wall 9e so that the thread cannot jump out of the eye gap 10a during continued travel of the eyes even in the event of vibrations.
  • FIGS. 3 and 4 show an example of a drive mechanism for moving the transport chains 11 and consequently the individual eyes 10 along the path on the eye bar while the eye bars travel longitudianlly, i.e., horizontally along the creel assembly.
  • the wheeled frame 7 which has a running wheel 12 resting upon the upper rail 5.
  • the wheel 12 is freely rotatable on its shaft 13 on which a Geneva gear 14 is fixedly secured.
  • the recesses 14a of the Geneva gear 14 sequentially engage with pins 15 of the rail 5 so that the Geneva gear 14 is shifted one division by engagement with each of the pins.
  • This intermittent rotation of the Geneva gear 14 is transmitted through the shaft 13 and a spur gear transmission 16 to a vertical shaft 17 on which a further spur gear transmission 18 is arranged at the height of each of the respective eye bars.
  • Each gear transmission 18 imparts rotation to a chain sprocket 19 engaged by the chain 11 for displacing the eyes 11) of the eye bar 9.
  • FIG. 4 Also visible in FIG. 4 is the portion 7a of the frame 7 which extends to the second running wheel 12a (FIG. 1).
  • Journalled on frame portion 7a is an arm 20 which is biased by a spring 211 counterclockwise with respect to the pivot 21 of the arm 20.
  • the free end of the arm 20 carries a rotatable roller 23 engaging the periphery of the Geneva gear '14 and snapping each time into one of the recesses 14a to thus arrest the gear so that the gear 14 moves only by engagement with the pins 15 but not in any uncontrolled manner.
  • the travelling frame 7 with the eye bars 9 is located at the rear of the creel assembly, that is at the left end of the equipment illustrated in FIG. 1.
  • the attending person seizes the junction 3 of the threads coming from the rearmost vertical row of thread guides 2 and places these threads conjointly into the first, left-hand notch of the thread holder 4.
  • each individual thread extending out of the eyes 2 is engaged by the contour 9d located at the creel-side end 90 of the eye bar 9.
  • the thread is thus guided in such a manner that it is located in front of the threading gap 10a of the most forward eye 10 which is being simultaneously shifted by the chain 11, this eye being the hook shown in FIG.
