Definitions

  • United States Patent The present invention relates to a yarn twisting apparatus.
  • the present invention is applicable to that type of well-known device in which a yarn package is located on a nonrotating support or tube which has an 1 opening concentric with the package so that yarn can move from the package substantially along the axis thereof.
  • the yarn is withdrawn from the package and passes downwardly along its axis, and then the yarn is rotated in the form of a balloon around the package by means of a bowl which is itself rotated and which is located beneath the package, the yarn being wound onto a receiving package after leaving the balloon.
  • the yarn is drawn through the apparatus either by the rotation of the receiving package itself or by forwarding rollers located at or near the top of the balloon.
  • Structure of the above type is known in the art as a double twist spindle or as a two-for-one uptwister, inasmuch as two twists are inserted into the yarn for each revolution of the spindle.
  • the rotary bowl has a cylindrical rotating surface on which part of the yarn is wrapped for the purpose of storing on the surface of the rotary bowl a portion of the yarn which, theoretically, is available for moving into or out of the balloon in order to maintain the length of the balloon constant so as to provide a yarn which has uniform twist characteristics.
  • this storage device has been provided so as to compensate for variations in yarn tension by storing more or less yarn, with the stored yarn occupying a greater or lesser proportion of the circumference of the bowl surface, so that the length of the yarn in the balloon itself will remain constant.
  • a further object of the present invention is to provid a device of the above type with a tension device which is simple in its construction and which is easy to adjust and which at the same time is self-cleaning, in that it is constructed in such a way that bits of flulf or fly cannot accummulate on the surfaces of the tensioning device.
  • Still another object of the present invention is to provide a structure for holding the package carrying carriage stationary without in any way interfering with the movement of the yarn and also while providing a radius of operation for a holding magnet and armature which is great enough to stabilize the bobbin and its support without any difficulty while being able to use relatively small magnets and/or being able to provide a relatively large gap between the magnets and armatures.
  • the invention includes in a yarn twisting assembly, a support means which supports a supply bobbin from which yarn is adapted to be withdrawn while travelling along a given path to a receiving package.
  • a yarn twisting means is located along the path of movement of the yarn to the receiving package, and in accordance with the present invention a tensioning means to also located along the path of movement of the yarn for tensioning the yarn as it moves from the supply bobbin to the receiving package.
  • the invention includes in a two-for-one textile spindle assembly, a ballooncontrolling ring mounted on the supply bobbin carriage and another balloon-controlling ring mounted on the framework of the assembly, the two rings being located at or above the position of maximum free balloon diameter, and a magnet is located on or near one ring cooperating With an armature on or near the other ring so as to restrict or stabilize bobbin carriage movement.
  • FIG. 1 is a partly diagrammatic elevation of one possible embodiment of an uptwister according to the present invention
  • FIG. 2 is a side elevation of a yarn tensioner capable of being used in the assembly of FIG. 1 and capable of automatically compensating for variations in the tension of the yarn as it is withdrawn from the supply package;
  • FIG. 3 is a partly sectional elevation showing the details of a tensioning means used with the embodiment of FIG. 1;
  • FIG. 4 is a view of a structure similar to FIG. 1 but without the tensioning means and showing the details of the structure for holding the bobbin-carrying carriage stationary during operation of the spindle.
  • FIG. 1 there is illustrated therein part of a framework 2 of a two-for-one spindle machine, this framework 2 carrying a bracket 1 on which a spindle mount 3 is supported.
  • a pivot pin 4 is carried by the bracket 1 and supports the spindle mount 3 for turning movement about the axis of the pivot pin 4, and the mount 3 has a limited turning range provided by the pivot 4.
  • the spindle mount 3 supports, in a suitable bearing, a rotary driven shaft 5 which forms a driven spindle, and this shaft 5 fixedly carries a pulley 6 which drives the spindle 5 by engaging a travelling belt 7 which, during operation of the machine, rotates the pulley 6 in order to rotate the spindle 5, whenever the pulley 6 engages the belt 7, which is to say whenever the mount 3 is placed in the operating position illustrated in FIG. 1.
  • the mount 3 carries a suitable bearing in which a manually turnable shaft 8 is supported for turning movement, and this shaft 8 carries at its left end, which is not visible in FIG. 1, a projection which engages behind a projection 9 fixed to the bracket 1.
  • the spindle mount 3 will be maintained in the illustrated operating position where the pulley 6 engages and is driven by the belt 7.
  • the operator can turn the shaft 8 so as to release its projection from the projection 9, and now the mount 3 can turn in a clockwise direction, as viewed in FIG. 1, about the axis of the pivot 4, and in this way the pulley 6 is moved away from the belt 7 to stop the drive and thus facilitate withdrawal of an empty spool and replacement thereof by a full package.
  • the handle 8 After the handle 8 is turned so as to release its projection from the projection 9, further rotation of the handle 8 in the same direction will move a brake 10, which is fixed to and projects radially from the bracket 8, through an opening in the mount 3 directly into engagement with the pulley 6 for braking the rotation thereof, and in this way it is possible to quickly bring the rotation of the spindle 5 to a stop.
  • the entire assembly can be turned back to the position illustrated in FIG. 1, and then the handle 8 is turned in the opposite direction so that its projection will engage with the projection 9 and thus hold the assembly in the operative position.
  • the projection 9 may be simply in the form of a block having at its side face which is not visible in FIG.
  • a vertical or slightly inclined groove or notch capable of receiving a pin projecting radially from the left end of the shaft 8 which is not visible in FIG. 1, and of course the shaft 8 fixedly carries suitable collars which permit the shaft 8 to be turned but prevent it from shifting axially in the bearings of the spindle mount 3.
  • the spindle 5 fixedly carries a bowl member 11 which is coaxial with the spindle 5 and rotates therewith, and the wall of the bowl 11 is formed with an opening in which a horizontal bush or sleeve 12 is fixedly mounted with is axis extending radially with respect to the spindle axis, so that the yarn may pass through the sleeve 12.
  • the bowl 11 has a smooth, circular outer surface 13 on which part of the yarn becomes automatically wrapped during the twisting operations.
  • the upper end portion of the spindle 5, which is not visible in FIG. 1, is enlarged and is provided with a bearing which supports a package-supporting means 16, in the form of a cylindrical carriage, with the support means 16 positioned coaxially with respect to the spindle 5.
  • the support means 16 is simply in the form of a vertical tube whose bottom end is received in the coaxial bearing of the shaft 5 so that in this way the shaft 5 is capable of rotating freely with respect to the support means 16.
  • the support means 16 carries the supply bobbin or package 17 from which the yarn which is to be Cir twisted is withdrawn in the manner described below.
  • the yarn which is withdrawn from the supply bobbin 17 passes from the supply bobbin upwardly to the top end of the tube 16 and then downwardly along the interior thereof, and from the interior of the package-supporting tube 16 the yarn passes in a manner well known in the art along the interior of the bowl 11 through the bush 12 to the exterior of the bowl 11, and the rotating spindle 5 forms from the yarn the balloon 44 which passes up through the stationary guide eye 45 to an unillustrated receiving package.
  • the support 16 fixedly carries a light shield 18 which separates the ballon from the package, and it will be noted that the shield 18 extends along the entire length of the package 17.
  • the shield 18 which is made of a suitable plastic or other nonmagnetic material, fixedly carries at an upper portion, adjacent to its top rim, or ring 123 (FIG. 4), a pair of magnetic armatures 26 (FIG. 4) which may be located at diametrically opposed parts of the shield 18. It is to be noted that the support means 16, the package 17, and the shield 18 do not rotate during the twisting operations.
  • the spindle mount 3 fixedly carries a post 20 which in turn carries a balloon-controlling ring 21, the latter surrounding the balloon so that the balloon 44 passes between the ring 21 and the shield 18.
  • This ring 21 fixedly carries, at diametrically opposed portions, two permanent magnets 22 which cooperate magnetically with the above-mentioned armatures 26 adjacent the top of the shield 18 for preventing rotation of the shield and the package 17, as described above, and of course the balloon 44 can pass freely between the upper portion of the shield 13 and the magnets 22.
  • a tensioning device 23 (FIG. 3) is carried by the top of the support means 16 and is inserted into the upper portion thereof, and this tensioning device acts on the yarn just before it enters into the tube 16 to move downwardly therethrough into the bowl 11 as described above.
  • an axially bored sleeve 30 is inserted into the top of the tube 16 and is provided with a shoulder which rests on the top edge of the tube 16.
  • the upper part of the tube 30 carries a bearing 33 the outer race of which is freely turnable and carries the fiyer 25 shown in FIG. 1.
  • the top of the tube 30 fixedly carries a lower tensioning element 32 in the form of an annular member having an upper annular surface located in a plane perpendicular to the axis of the tube 16, and this upper surface of the ring 32, which may be separated from and fixed to the tube 30 or which may be integral therewith, forms one of the tensioning surfaces of the tensioning device of the invention.
  • the tensioning device includes a second tensioning element in the form of a disc 42 having a downwardly directed annular surface also located in a plane which is normal to the axis of the tube 16 and directly engaging the upper surface of the ring 32. This disc 42, in the embodiment of FIGS.
  • weights 40 may simply be threaded onto a threaded portion of the stem 39 which is fixed to the upper tensioning disc, and this tensioning disc 42 which simply rests on top of the tensioning ring 32 is provided in its interior with a downwardly directed rim located within and spaced from the ring 32, as shown in FIG. 3, so that in this way lateral shifting of the tensioning disc 42 is avoided.
  • the pair of tensioning elements 32 and 42 are made preferably of hard steel.
  • the yarn 24 passes through an eye at the end of a freely rotatable flyer or arm 25, and then from this eye the yarn passes between the tensioning surfaces, slidably engaging the latter, and then into the support 16 downwardly along the latter.
  • the yarn 24 circles around the package 17 as it is withdrawn therefrom, and the flyer 25 turns freely with the yarn, and the yarn also turns around the axis of the stationary support 16 as it slides on the tension surfaces, thus moving around and around over all parts of the friction surfaces, and in this way these surfaces are kept clean.
  • the yarn tension varies as the package decreases in size during the unwinding of the yarn therefrom.
  • the presence of the yarn tensioner of the invention at the top of the support 16 insulates these variations in the yarn tension from the part of the yarn which moves beyond the yarn tensioner down through the support 16, so that beyond the tensioning device of the invention the fluctuations in yarn tension resulting from removal of the yarn from the supply package do not influence the introduction of the twist into the yarn, and also, as pointed out above, the tension device assists in the suppression of undesired oscillatory motlon of the flyer during starting and stopping of the uptwister.
  • the yarn tensioning device of FIG. 2 is simply inserted into the tube 16 in the manner described above.
  • the flyer 34 corresponds to the flyer referred to above and includes an eye 43 through which the yarn passes from the supply bobbin 17.
  • the rotary outer bearing ring 33 which carries the fiyer 34 also carries, fixedly, an upwardly extending relatively short arm which supports a pivot 36 which serves to pivotally support on the notary ring 33 an elongated lever 35 having two arms extending in opposite directions from the portion of the .lever 35 which is connected through the pivot 36 to the rotary bearing ring 33.
  • the outer arm of the lever 35 threadedly carries a screw 33 which serves to adjustably fix to the lever 35 an elongated wire 37 also provided with an eye at its free end, as indicated in FIG. 2.
  • the left end of the wire 37 is formed with a loop which is elongated and which has a width which is less than the diameter of the head of the screw 38, so that this screw 38 may be loosened in order to adjust the extent to which the wire 37 projects beyond the lever 35, and then the screw 38 may be tightened to fix the wire 37 to the lever 35, and in this way the position of the eye at the end of the wire 37 from the axis of the tensioning device can be regulated.
  • the nner arm of the lever 35 fixedly carries the stem 39 which in this case is not fixed directly to the disc 42. Instead this stem 39 is fixed at its bottom end to an enlarged head whose downwardly directed surface presses on a ball member 41 which is carried by the disc 42, and in this way the weights 40 on the stem 39 serve to urge the lever 35 to turn in a counterclockwise direction, as viewed in FIG 2, these weights still urging the disc 42 downwardly against the ring 32 by engaging the ball 41.
  • the bottom end of the stem 39 in this case simply turning on the uppermost part of the hard metal ball 41 so that there is a minimum frictional resistance to the turning of the lever 35 with respect to the disc 42.
  • the yarn which comes from the supply package 17 passes through the eye 43 of the flyer 34 and then through the eye at the outer end of the wire 37, and from this latter eye the yarn passes between the friction surfaces of the tensioning elements 32 and 42, and then down the axial bore of the insert 30 and downwardly along the interior of the support 16 into the bowl 11 as described above. ]if the tension in the yarn as it moves from the package 17 tends to increase, the yarn itself will act on the W111?
  • the tension in the yarn tends to be greatest when the yarn is withdrawn from the bottom of the package and smallest when the yarn is withdrawn from a point part of the way down the surface of the package, and these tension variations will thus be automatically compensated, as well as tension variations which are relatively high when the package is of a maximum diameter.
  • the insert 30 engages the inner surface of the tubular carriage 16 with a sliding fit which is of sufiicient tightness to prevent rotation of the member 30.
  • weights are preferred to springs for the purpose of loading the tensioning device since the weights can be colored and thus seen through the balloon so that the amount of loading is immediately visible, and in addition the amount of loading is exact and does not require calibration as would be the case if a loading spring were used.
  • this structure operating so that the action of the lever 35 will decrease the loading on the disc 42 as t increases, and increase the loading as t decreases, the ratio of the lever-age being adjusted so that the loss in yarn tension caused by a loss Olf loading is equal to the increase in the tension t and the increase in tension caused by an increasing value of t will be accompanied by a compensating loss of loading. It is thus possible, within certain limits, to provide a yarn tensioner as described above which will maintain a constant out-put tension irrespective of input tension.
  • the degree of hindrance of twist propagation at the twist inserting device is affected not only by the condition at the direction-changing point where motion of the yarn ceases to be radial to the device and becomes circumferential (e.g., eyelet 12) but also by the angle of lap around the yarn storage device.
  • the rate of twist propagation is maintained constant.
  • the effect of this process and apparatus of the invention is to avoid surging of twist from one point to another in the system, this surging, which takes place in other systems, causing gross short-term variations in twist content in the yarn.
  • FIG. 4 shows the pair of diametrically opposed magnetic armatures 26 carried by the shield 18 near its top rim ring 123.
  • the package 17 and the shield 18 as well as the carriage 16 do not rotate during twisting, and the rim or ring 123 acts as an inner balloon guide.
  • the pair of magnets 22 which are carried by the stationary outer balloon control ring 21 coact with the armatures 26 mounted on top of the shield 18 to prevent rotation of the shield and package 17.
  • the balloon 44 passes between the inner rim ring 23 and the outer control ring 21 to the takeup package (not shown) via the top guide 45.
  • the balloon restricting means is located at or near the position of maximum free balloon diameter where the magnetic stabilizing means is located.
  • the ring or rim portion 123 is located at or above the midposition of the bobbin 17, and although a pair of armatures 26 are shown fixed to the nonmagnetic shield 18 at least one armature is necessary, and at least one permanent magnet 22 cooperating therewith.
  • the pair of rings 123 and 21 are provided with smooth balloon-engaging surfaces adapted to limit the expansion or contraction of the balloon to a required diameter, and the yarn may engage with either one or both of these rings during its passage from the inner rotating bobbin to the take-up bobbin.
  • the bobbin carriage can be provided with a smooth-surfaced projection, and the axis of the carriage can be positioned eccentrically with respect to the fixed ring in such a manner that undue rotation of the carriage causes engagement and jamming of the projection against the fixed ring.
