Application November 10, 1951, Serial No. 255,7 79

13 Claims.

The present invention relates to textile winding machines and comprises a novel machine of this type which has a high output per square foot of floor space, is substantially noiseless in operation, is economical to construct and operate, easy to replenish and doff and operates with a minimum of ends down. The machine winds uniform and accurate packages without hilling at the ends of the bobbins, without ridging along the barrels of the bobbins, and the traverse means thereof may be readily changed for winding of different shaped packages. The machine of the invention is an improvement over the redraw machine described and claimed in applicants copending application Serial No. 131,538, filed December 7, 1949.

The new machine is of circular configuration with the drive means located in the central portion of the machine, the rotating spindles carrying the bobbins to be wound arranged in a circle about a central support post and with the supply creel arranged in an outer circular zone. The traverse means, which rotates unidirectionally about the central support post in a circular path between the creel and the spindles, is of the general type of that of the machine described and claimed in the said copending application in that it comprises a member having an edge contoured in a series of hills and dales over which the yarn from the supply packages is led in transit to the spindles.

For a better understanding of the invention and of a preferred embodiment thereof, reference may be had to the accompanying drawings, of which- Fig. 1 is a perspective view, partly broken away and with some details omitted, of a machine embodying the invention;

Fig. 2 is a fragmentary top plan view of the machine of Fig. l with the cover removed to show the drive mechanism;

Fig. 3 is a vertical sectional view, partly in elevation, of the machine of Fig. 1;

Fig. 4 is a detail side view of a single spindle showing the drive and brake therefor; and

Figs. 5 and 6 are horizontal and vertical sectional views, respectively, of the means for cyclically varying the relation between the rate of rotation of the spindles and the rate of travel of the traverse means.

A general description of the new machine will first be given with reference to Fig. 1. The machine includes a lower cylindrical casing or skirt 2 which carries the supply creel and an outer circular guard rail 4. The skirt is mounted on a base 6 adjustably supported above the floor on foot pads 8. An upper skirt [0 of larger diam;- eter, which is supported from the upper portion of the skirt 2 by a support ring II of wood or the like, terminates about its upper'periphery in an outwardly flaring shield 12 for the rotary traverse means 14, the shield being double-walled and provided with a plurality of yarn guide slots it. A plurality of spindles, take-upbobbins on which are. indicated at It in Fig. 1, are rotatably supported adjacent the inner wall 26 of the slotted guard l2 with their axes inclined to the vertical and generally parallel to the slots I6, there being one slot l6 for each spindle. A cylindrical cover 22 having a slightly domed top encloses the drive means for the traverse rotor and for the spindle drive belt. The traverse means i4 rotates in the annular space defined by the inner and outer walls of the shield. It has an upper yarn engaging edge 2i that is so contoured as to form a series of hills and dales. In the particular embodiment of the invention illustrated in the drawings, the traverse means is shaped for the winding of cylindrical packages and therefore the slope of the edge 24 between a peak 26 of a hill and the bottom 28 of the next succeeding dale is uniform. The peak 26 of each hill is alined with the upper ends of the barrels of the bobbins to be wound and the bottom 28 of each dale is aimed with the lower ends of the bobbin barrels so that, as the contoured edge 24 travels by a bobbin, the yarn travels up and down in the guide slot I6 associated with that bobbin and traverses the full length of the barrel.

' Interposed in the yarn flow path between the supply creel and the guide slots 16 are yarn guide and tensioning means each comprising two pigtail guides 29 and two disk tension devices 30 mounted on a slotted base 32. Each base 32 rests on a rail 36 supported by radially disposed brackets 38 secured at their inner ends to the under side of the support ring Ii, the rail 36 passing through the slots in the bases 32.

The guard rail 4 is mounted on the outer end of a plurality of pairs of brackets 40 and 4|, the inner ends of which are secured to the skirt 2. Each bracket 4| carries an upstanding pin 42 by means of which a yarn supply package, such as indicated by the reference numeral 44 in Fig. 1', is supported on the bracket. Brackets 46 mounted on the skirt 2, carrying angularly disposed pins 48, serve to support additional supply packages and complete the creel.

Referring now to Fig. 3, it will be noted that the machine is built around a central hollow bored post 50 which is supported on the base 6 by bolts 52 and which has mounted thereon by means of bearings 54 a rotatable sleeve 56. The sleeve 56 by means of tension rods 58 and collar 59 supports a rotor platform 60 on the upper outer surface of which are mounted two traverse support rings 62 and 64 each of which has an inclined surface to which the segments of the traverse rotor 1 are secured by screws as shown in Fig. 3, ring 62 being of larger diameter and supported above the platform 60 by spacers 66 which insure that the traverse engaging surfaces the axis of the post and with teeth on ritsaouter V periphery in engagement with a drive pinion 'II]. Pinion 7B is carried on thedower --end of a-shaft I2 journaled at its lower end-irrbea-rings mounted in the main support platform 14 of the machine and at its upper end in bearin ammlnted; in ,a change gear arm 76. Shaft I2 carries a gear 18 at its upper end, the drive means for which will presently be described.

The walls 1 12a and I 12b are mounted on the spindle bracket as by-rivets1-iI l4. A 'manually operable'aarm I16 is fixedly secured to lever I68 or formed integral therewith, a knob I18 being mounted on the free end of the arm. Thus when an operator moves the arm I16 in the direction of the arrow in Fig. 4, that is, away from the spindle, the collar I66- pulls spring wire I64 which in turn pulls the brake shoe I60 into braking engagement with the whorl I stopping the spindle, overcoming driving belt means I02. Rivets or pins I80 and I82maintain the walls I120 and I121) in spaced relation and serve as limit stops for lever Mounted on the lower-skirt 2 of the machine is a switch box and plug-in unit I84 and reversing switch I86 for the motor I04, the wiring to the motor being omitted from the drawings. 7

In order to insure proper alinement of the guide slots I6 with the spindles, means are provided for adjusting through a limited angle the position of the spindle mounting ring 88. These means comprise a rack I88 (see Fig. 2) fixed to the ring 88 and a cooperating drive pinion therefor mounted in a bracket I90 fixed to the platform 14, an operating unit for the shaft of the pinion being indicated at I92. Arms I94 and I96 fixed to the ring 88 and extending over the platform 14 carry bolts I98 and 200, respectively, which, by engagement with one of the vanes 80, serve as adjustable limit control stops for the ring 88.

In threading up theabove described running machine, the operator, after braking a spindle by movement of arm I16 draws an end of yarn from a supply package 44, threads the end through one guide 29, then between the disks of each pair of tension disks 30, out through the other guide 29 and then wraps the end for a few turns around an empty take-up bobbin I8. The bobbin is then placed on the spindle with the yarn passing through the associated slot 16 in the traverse shield I2. Upon releasing the spindle brake by manipulation of arm I16, or upon energization of motor Hi4 by switch I84 if the machine had not previously been placed in operation, rotation of the spindle takes up slack in the yarn and thereby brings it into engagement with the contoured edge 24 of the traverse rotor. Rotation of the traverse rotor, efiected through the means heretofore described, causes the yarn to ride up and down in the slot I6, traversing the bobbin and, with the particular contour of traverse rotor illustrated, building a cylindrical package. When there is substituted for the particular traverse rotor illustrated, one in which the upper edge on both sides of a peak is curved concavely, the upper part of the barrel of a bobbin will be traversed at a higher rate than the lower part of the-bobbin and hence a tapered package is formed as described in the said copending application. During building of the package, tracking of one layer of yarn on the preceding layer, which results in ridging of the winding, is avoided by a plus and minus per cent cyclical variation of the rate'of rotation of the traverse rotor, resulting from the periodic movement of the lower sheave IIBb by the cam plate follower I3-6 as heretofore described. I-Iilling, ridging or patterning as it is sometimes called, by proper contouring of the yarn guiding edge of the traverse means I4. It will be apparent that in a traversing operation the yarn must be delivered to the bobbin at a slight angle with respect to a plane perpendicular to the bobbin axis, which angle is termed the lead angle. By changing the lead angle, the numberand spacing of helices or; yarn wound on a given bobbin can be varied as de sired. In the case of the parallel wind bobbin, it is contemplated that the traverse means I4 will be so contoured as to maintain the lead angle constant as the flange of the bobbin is approached and to reverse such angle instantaneously at the moment the yarn contacts the flange. As a result of the yarn'being the only element in reciprocation, the inertia of the system is negligible which permits extremely high acceleration and deceleration and, consequently, accurate full flange to flange winding in each cycle of the operation without trapping of the yarn at the flanges, at higher winding speeds than has heretofore been practical. Y

From the foregoing description of the illustrated machine and of the operation thereof, it willbe apparent that the invention provides a practical and eflicient textile winder. Due to the circular configuration with the parts primarily supported from a central post, a mechanically rugged machine is obtained. The unidirectional travel of the traverse rotor insures relatively silent and rapid operation and the disposition of the supply creel on the main skirt permits easy access thereto by the attendant for replenishing and piecing up of ends. The circular construction with the central hollow post permits of ready lubrication of the moving parts and the removable domed cover permits of access-to the drive mechanism for inspection, replacement or adjustment.

The following information relating to a machine constructed in accordance with the inven-' tion is indicative of the superiority of the new circular machine as compared to conventional machines now in wide use in textile mills.

The particular machine is about seven feet in diameter at the guard rail and about five feet from floor to top of cover. There are ZQspindles set at 35 degrees with respect to the vertical. The takeup bobbins have a traverse length of four and one-half inches and a barrel diameter of two and one-fourth inches. The speed range is from 720 to 4800 R.P. M. which, 'for the particular bobbins used, corresponds to an average. of to 1200 yards per minute. As compared to a conventional winder now in common mill use, there is a direct saving in labor as the time required for doffmg and replenishing 'theJnew machine is substantially less for the new I'na-' chine. The cost of fixing labor, due to the absence' of conventional reciprocating traverse means, is reduced substantially by one-third with the new machine. Breaks per cake at the new winder are about one-half the conventional winder and breaks at the twister when twisting yarn wound on the new machine are substantially less than when twisting yarn wound on the conventional machine. The average practical yarn speed of the new winder is many times that of the conventional machine (75'd-enie'r'vis cose cakes are run at 700 yards per minute on the new machine as compared with 180 yards per minute on the conventional machine),'"re-' sulting in substantial saving in overhead and in indirect labor cost and in greatly increased output per spindle hour. Above all, the packages found on the new machine are superior to those wound on the conventional machine, resulting in elimination of rejects with their attendant waste in material and labor, Th vention has now been described with reference to one specific embodiment thereof. Obviously, various changes in the particular construction 2' illustmted (and described would be made .without. i departing rfrom {the spirit. of the invention Qr-Qthe scopeof, the accompanying -.olaims.
