Definitions

  • ABSTRACT A filament feeding device in which filament from a supply thereof is tangentially wound about a storage drum from which said filament is axially withdrawn.
  • a housing which is fixed has a cavity within which the storage drum is removably seated.
  • the outer contour of the drum and the confronting inner contour of the cavity are matingly shaped so as to define a radial gap therebetween and also so as to prevent significant relative rotation between the drum and the housing whereby the drum is in effect floating within the housing, being unsecured thereto.
  • the filament tangentially wound about the drum forms a plurality of windings which advance axially within the radial gap and is thereafter withdrawn axially through an aperture at the opposite end of the housing.
  • the mating confronting contours of drum and housing may be oval shaped, polygonically shaped, or be shaped in any other non-circular contour which results in preventing relative rotation between the drum and the housing.
  • the present invention relates to filament or yarn storage and feeding devices used in association with textile producing apparatus, particularly knitting machines, but relating as well to weaving and spooling apparatus.
  • the supply of yarn is in the form of a plurality of yarn cones with the yarn being drawn from the cone by the needles.
  • yarn As yarn is drawn off the cone, it undergoes substantial variations in tension due to the manner in which the yarn package is formed on the cone and unwound therefrom.
  • the yarn supplied from any one cone is likely to be under different tension from that supplied to the needles at the same time from any of the other cones, resulting in the production of goods which are nonuniform, inferior in quality, and often considered as being defective.
  • Efforts have previously been made to resolve the problems pointed out above by providing an intermediate yarn storage device disposed between the yarn cone and the needles..Examples of such storage device are shown in U.S. Pat. Nos.
  • a yarn storage feeder which isvoid of the deficiencies pointed out above and which is generally a greatly improved storage feeder both in efiectiveness and the I quality of performance, while the cost thereof is substantially reduced.
  • the storage drum is supported within the device by being seated in the cavity of a support member therefor.
  • the confronting contours of the storage drum and its seat are shaped so that the drum is prevented from having any significant rotation with respect to the seat, without requiring any and in this condition there is a twist imparted to the means for fixedly securing the drum within the device,
  • the drum in accordance with the invention, can be characterized and is hereafter referred to as a floating drum, being freely removable and insertable within the device.
  • the outer contour of the drum surface is oval shaped, as is the inner contour of the support therefor, there being a small radial clearance between said contours to enable yarn wound onto the drum to be advanced axially therealon'g.
  • the oval configuration of the drum and support therefor prevents any significant relative rotation between the floating drum and its support. Since the support is fixedly mounted on the knitting machine, the drum remains substantially stationary without requiring independent securing means which otherwise have to be devised so as not to interfere with the path of the yarn. in other respects, the storage BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a storage feeder in accordance with the invention
  • FIG. 2 is a sectional view taken along line 2-2 of FIG. 1;
  • FIG. 3 is a view taken along lines 3-3 of FIG. 2;
  • FIGS. 4, 5 and 6 are views similar to FIG. 3 but showing various modifications thereof.
  • FIG. 7 is a view similar to FIG. 2 showing another embodiment of the invention.
  • Storage feeder 10 includes a frame member 12 which is adapted to be 'affixed to the knitting machine in any suitable manner.
  • Frame member 12 as best shown in FIG. 2, fixedly mounts a hollowed out member 14 whose cavity 16 comprises a first section 16a of uniform cross section, best shown in FIG. 3, a conical second section 16b, and a third section 16c having a reduced cross section.
  • a storage drum 18 is supported by member 14 within its cavity section 16a.
  • Storage drum 18 comprises a flange 20 at its upper end, a uniform cross section main body portion 22 and a short generally conical section 24 between flange 20 and main body portion 22.
  • cavity section 16a has an inner contour which is oval shaped and complementary to the oval shaped radially spaced confronting outer contour of storage drum main body portion 22. Accordingly, and as best shown in FIG. 2, when the storage drum is inserted within cavity 16 of its support member 14, the inner upper rounded edge 26 of cavity section 16a will supportingly engage conical section 24 of the drum so that the outer surface of drum portion 22 will be spaced from cavity section 16a with a radial gap 28 surrounding the storage drum.
  • the axial length of drum 18 is related to the dimensions of cavity 16 so as to provide a clearance 30 between bottom edge 32 of the drum and cavity 16. It will be evident that with the storage drum so supported within cavity 16 of support member 14, the mating confronting contours of storage drum and support therefor, being oval, prevents any significant relative rotation therebetween.
  • a tubular sleeve 34 is mounted for rotation about fixed support member 14 by means of bearings 36, said sleeve being provided with a yarn guide 38 through which yarn Y from a supply thereof can be threaded.
  • Sleeve 34 is thus mounted for rotation about fixed support member 14 and may be driven by means of belt 40 which is in engagement with pulley 41, the latter being driven by a motor M or any other suitable driving member.
  • tubular sleeve 34 when driven, defines a winding member whereby yarn passed through guide to the yarn as it passes between the ball and socket on its way toward the knitting machine needles.
  • the drum is stationary without however being required, as in the prior art, to be fixedly secured to the yarn storage device.
  • the sole physical engagement of the storage drum within the storage feeder is along conical section 24, with the yarn being wound passing between conical section 24 and upper edge 26 of support member 14.
  • storage drum 18 is preferably hollow, as shown at 49, and made of lightweight material whereby the tension applied to the yarn as it passes between the drum and its supporting member 14 is maintained at an acceptable level which does not interfere with the winding of the yarn onto the drum.
  • a feeler 52 having a curved sensing portion 54 resiliently urged against the storage drum and a switch arm portion 56 terminating in an electrical contact member 58.
  • the full lines in FIG. 2 show feeler 52 in a first position in which electrical contact 58 is in engagement with another electrical contact 60 (suitably insulated from the housing) to complete a circuit (not shown) which is operative to maintain rotation of winding member 34.
  • sensing portion 54 assumes the dotted line position shown in FIG.
  • photo electric means and other means such as shown in said aforementioned U.S. Pat. applications Ser. Nos. 136,939 and 184,527, may be easily adapted for controlling the minimum and maximum quantities of yarn to be maintained on the storage drum regardless of the yarn demand made on the storage feeder by' the knitting machine needles.
  • the essential feature of the present storage feeder is in the provision of a floating storage drum which, though unsecured to the storage feeder itself, and removable therefrom if so desired, nevertheless remains substantially stationary to enable yarn to be wound thereabout tangentially for subsequent removal axially.
  • This object is accomplished by providing mating noncircular contours for the drum and its supporting mem ber whereby to simultaneously define a radial gap therebetween to permit winding and advancing of the yarn onto the drum while preventing the drum from having any significant rotation other than incidental minute back and forth motion which does not interfere with the unimparied advancement of the yarn as intended.
  • FIG. 3 the confronting contours of the drum and its fixed support are essentially oval shaped.
  • the same result, however, can be accomplished by using other mating confronting contours so long as they are shaped to prevent relative rotation of one with respect to the other while still defining a substantially uniform width gap between the drum and its fixed surrounding support member. Illustrations of other embodiments of the invention are shown in FIGS. 4 through 6.
  • the contour is a multi lobe conic.
  • FIG. 5 the contour is a polygon and particularly a hexagon, and in FIG. 6, the contour is of a hybrid nature.
  • a gap 28', 28", and 2fi"' is provided between the storage drurn main body portion 22', 22", 22"and its associated support 14, M", and 14', respectively, of sufficient width to prevent any significant relative rotation therebetween.
  • FIG. 7 shows another embodiment of the invention wherein a floating drum is provided.
  • the embodiment of FIG. 7 is substantially identical to that of FIG. 2 except only that the axial length of storage drum 1% is slightly greater in the embodiment of FIG. 7 than it is in the embodiment of FIG. 2. Accordingly, when the storage drum is inserted within cavity 16 of support member 14, the bottom edge 62 of the drum will engage and be supported by conical section 166 of cavity 16, and conical section 24 of drum 18 will be spaced from'upper rounded edge 26 of cavity section 16a to define a clearance 64 therebetween for passage of the yarn as it is wound onto the floating drum.
  • the yarn being withdrawn axially from the drum passes between drum 22 and cavity wall section 16b on its way out of the storage device.
  • the drum and support member 14 collectively define a tensioner for the exiting yarn making it unnecessary to provide an additional tensioning device for the exiting yarn.
  • the weight of the floating drum can be selected so as to provide the requisite level of tension on the exiting yarn.
  • the confronting contours of drum 22 and cavity section 16a may be oval or of other matching shape so long as the contours are such as to prevent any significant relative rotation between drum and support member M, and a gap is provided between the drum. and the support to enable unimpaired axial advancement of the yarn wound onto the drum by winding member 3%.
  • a filament feeding device comprising,
  • said support means comprising a housing fixed to a frame member and being open ended at one end thereof to define a cavity within which said drum is removably supported,
  • the outer contour of said drum and the confrontin inner contour of said cavity being matingly shaped so as to define a radial gap therebetween and prevent significant relative rotation between said drum and said support means; and e. means for winding said filament about said drum adjacent one end thereof for forming on said drum 5 a plurality of windings which advance toward the other end of said drum within said radial gap.
  • a filament feeding device in accordance with claim I wherein said support means is provided with an aperture opposite said one end thereof through which the filament wound about said drum travels as it is withdrawn axially of the drum.
  • a filament feeding device in accordance with claim 2 wherein a peripheral edge is defined at said one end of said housing about said cavity and said drum is provided with a peripheral flange at one end thereof whereby said peripheral edge supportingly engages said peripheral flange for supporting said drum within said cavity.
  • winding means comprise a tubular sleeve mounted for rotation about said support means and having yarn guide means adjacent said one end of said drum.
  • said winding means comprise a tubular sleeve mounted for rotation about said support means and having yarn guide means adjacent said one end of said drum.
