Abstract

Method and apparatus are disclosed for transferring yarn from a completed yarn package to an empty reel in a continuous yarn winding process whereby a plurality of yarn winding arbors are rotated around a centrally located drive roller. Rotation is caused by interaction of spring tensioned arbors along a cam guide which positions the arbors relative to the drive roller.

FINK ATTORNEI i CONTINUOUS YARN WINDING APPARATUS The present invention relates to a method and apparatus for transferring yarn from a completed yarn package to an empty reel in acontinuous yarn winding process. It has become apparent in recent years that it is advantageous to maintain as nearly constant conditions as possible while processing synthetic yarns. Reasons for attempting to normalize the conditions are many and varied.

The deviations are especially amplified during attenuation and- /or texturing operations.
Furthermore, continuous winding has the advantage of more effective utilization of processing machinery by increasing'output'per period of time since downtime between doffing the packages is virtually eliminated.
Therefore, an object of this invention is to provide a method and apparatus for normalization of yarn winding conditions.
A further object of this invention is to provide appa: ratus to continuously wind yarn in as nearly constant conditions as possible to minimize yarn processing deviations.
A further object of this invention is to provide a method of transferring yarn from a completed package of predetermined size to an empty reel in a continuous yarn winding process.
There have been numerous proposals for achieving continuous winding, involving complicated cam and gear arrangements and various other transfer mechanisms. The present invention incorporates simple, proven mechanical elements to effect a durable and reliable continuous winding apparatus. Utilization is made of a central peripheral nip-drive roller to which a series of yarn winding arbors are sequentially brought into contact. The yarn winding arbors are attached to a rotatable turret mounted on the winding frame concentric with the drive roller. The spacial relationship of the arbors to the drive roller is determined by a cam guide attached to the frame of the apparatus. Means are provided for restraining yarn from being traversed by a conventional yarn package forming traverse means upon completion of a yarn package disengaging the yarn from the completed package, winding a number of loops for transfer tail purposes on an arbor brought into contact with the drive roller, and then reengaging the traversing mechanism to begin winding a new package. Further means are provided for disengaging the completed package from the drive roller in preparation for doffing.
BRIEF DESCRIPTION OF DRAWINGS FIG. 5 describes the multiple function program timing sequence. 7
Referring to FIGS. 1 and 2, it will be seenthat the winding mechanism chosen for purposes of illustration includes as components thereof, an equipment frame 21, a turret 22 with moveable rotatable windup arbors 23 through 26, a drive roller 32 concentrically located with said turret 22, a reciprocating traverse guide 33 through which yarn 48 advances: between drive roller 32, and package 34 on arbor 23, a yarn deflecting device 41, and a multiple function programmer 37. The turret 22 comprises a rim 60 attached to a hub 61 by a series of spokes as represented by 46 and 47. The spokes act as windup arbor guides as shown in FIG. 1.
In operation, when package 34 has reached a predetermined size, limit switch 36 is tripped, actuating multiple function programmer 37. Programmer 37 may consist of any number of types of conventional. timing devices for actuating the various elements to be explained herein. Upon actuation by limit switch 36, programmer 37 activates detent solenoid38 which pulls cam rod 42 from its locking detent position and allows turret 22 to be rotated. Rotation is produced by the in teraction of cam guide 43 and arbor 24, said arbor 24 being pulled toward the drive roller 32 by means of springs 44 and 45 along arbor guides 46 and 47, to be more fully explained. Rotational movement is also enhanced by the weight of package 34 producing a moment force acting upon turret 22 around the driver roller 32. Simultaneously, arbor 24 is being brought into a ready position for receiving yarn 48.
Package 34 remains in contact with drive roller 32 until arbor 24 with empty package support reel 28 is brought into position, brought up to speed, and yarn 48 is deflected by yarn deflecting guide 41 (shown here in normal running position) to reel 28. Package 34 is then disengaged from the drive roller and made ready for doffing.
In FIG. 3, yarn 48 is shown passing through traversing mechanism 33 over drive roller 32 onto package 34 in its rotated position. Arbor 24, with its empty package support reel 28, is in contact with drive roller 32. The yarn deflecting guide is shown in its extended position, denoted 41 with an intermediate position denoted by the broken outline 41 in normal running position denoted 41. As turret 22 (FIG. 1) rotates about the drive roller 32, package support reel 28 comes into contact with drive roller 32. Programmer 37 then activates rotary solenoid device 51, bringing yarn deflection guide 41 into its intermediate position 41'. As yarn 48, being guided by traversing mechanism 33, approaches the deflection guide 41 it slides over edge 53 and falls into notch 54, which restrains movement along package 34. Programmer 37 then actuates rotary solenoid device 52, rotating the deflection guide to its extended position 41", carrying the yarn 48 upward and into the path of yarn snaring device 55 located on arbor 24. Simultaneously, the yarn is guided onto package 34 by cutter guide 56. As the yarn crosses into the path of yarn snaring device 55, it is caught and the resulting tension in yarn 48 from the rotational pull of package 34 and the snaring device 55 causes the yarn to be carried to surface 57 of cutter guide 56. The yarn deflection guide remains in its extended position 41' while a number of convolutions of the yarn are formed on arbor 24 to form a tail for the package to be formed on support .reel 28. Programmer 37 then de-activates versing mechanism 33 begins feeding the yarn 48 directly onto package support reel 28.
FIG. 4 shows the relationship between cam guide 43 and arbor 24. When detent cam rod 42 (FIG. 1) is retracted, roller 62 on arbor 25 is urged from detent notch 63 in cam guide 43. The tangential component of the interacting force caused by springs 44 and 45 acting at point 58 between arbor 24 and cam guide 43 initiates rotation of turret 22 in a counterclockwise direction, while the radial component of this force pulls arbor 24 and package support tube 28 along guides 46 and 47 (see FIG. 1) and into contact with drive roller 32. Furthermore, as full package 34 is rotated from its top dead center position, it adds an additional rotation producing torque on turret 22. When rotation has been completed, full package 34 and empty package support tube 28 are in contact with drive roller 32, ready for transfer of yarn.
FIG. illustrates the timing sequence of multiple .function programmer 37. When limit switch 26 has actuated programmer 37, said' programmer activates turret detent solenoid 28 for a sufficient amount of time to allow rotation of turret 22 through 90. Rotary solenoid 51 is then activated for a length of time sufficient to capture yarn 48 during a stroke of the traversing mechanism 33. Both rotary solenoids 51 and 52 are actuated for the time required to transfer yarn to arbor 24, severe the yarn, and form a tail on said arbor.
