Definitions

  • This invention relates to builder motions such as are used for actuating a winding traverse in the operation of yarn spinning and twisting machines and the like, and more particularly to a uniquely improved builder motion of this sort by which the specific winding traverse required for any given form of yarn package can be provided fo .and controlled to exceptional advantage, f
  • the builder motion of the present invention operates with singular effectiveness, for example, in the winding f filling or shuttle bobbins for use in automatic loom batteries, and for which purpose the filling bobbins must be built to include not only the usual feeler bunch as a part of the main yarn package, but a tip bunch as well that is required at .a spaced disposition above the main package for use in automatically finding and retaining the package end as the battery operates to deliver the bobbins successively.

Threaded leveling plugs 12 are provided on the main housing 10 so that its mounted disposition may be squared properly in relation to a main input drive shaft 13 journalled in a housing bracket 14 and extending from any suitable power source (not shown).
  • the input shaft 13 may be extended from the head end worm drive normally provided for the builder, .and the ieveling plugs 12 allow the housing 10 to be squared readny in relation to this drive source upon installation.
  • the housing bracket 14 carries the input shaft 13 in offset relation so that it may be attached to the main housing 10 at more than one position by the same attaching screws 14' to provide for adjusting the position of the builder motion to the space available in the spinning frame or other machine on which it is to 'be installed.
  • the input shaft 13 extends inwardly through the housing bracket 14 to carry a spur gear 15 in mesh with a paired gear 16 fixed on a main builder shaft 17, that is journalled centrally in the housing bracket 14 at one end and supported by the housing cover plate 11 at its other end.
  • a sprocket wheel 18 Adjacent the spur gear 16, a sprocket wheel 18 is doweled on the builder shaft 17 (as indicated at 18'), and has an oscillator cam 19 attached thereto by screws 19', so that both of these elements are fixed on the builder shaft 17 to be rota-ted therewith by the drive from the input shaft 13.
  • the sprocket wheel 18 has a chain 20 trained thereover that extends also about a lower sprocket wheel 21, to drive a suitable pump means 22 for circulating lubricant from a housing sump portion at 23 to ran overhead drip pan at 24; and about a lateral sprocket wheel 25 from which a letoii action is operated in the manner described in detail further below.

  • the purpose and operating arrangement of the oscillator cam 19 is described in particular further below.
  • the remaining extent of the builder shaft 17 is fitted with bearings 26 to support the hub of a worm wheel 27 for rotation thereon.
  • the worm wheel 27 is formed to have a cycling cam 2S assembled coaxially therewith by attaching screws as indicated at 28' in FIG. l, and the worm wheel hub portion extends through a bearing support at 29 in the housing cover plate 11 to carry a plug 30 for receiving an attaching screw 30" by which a radial arm member 30 is fixed at the extending hub portion end to rotate with the worm wheel 27.
  • the housing cover plate 11 In vertical alignment below the builder shaft 17, the housing cover plate 11 is vertically slotted to allow disposition at the cycling cam 28 of a follower roll 31 that is carried by the lower end of a slide member 3-2 arranged at the outer face of the cover plate 11 in a slideway ⁇ structure 33 (compare FIGS. l, 2 and 8) to deliver the traverse movement.
  • a cable 34 or the like is extended from the upper end of the slide member 32 over an idler pulley 35 to a jack shaft pulley 36, the slideway structure 33 having an upper housing portion 33 formed to carry the pulleys 35 and 36 on respective shafts 37 and 38 with the jack shaft 38 extended exteriorly for connection in any usual or suitable manner (not shown) to operate the machine elements that are to be traversed.
  • the oscillator cam 19 is seen to be a threelobe cam of the type commonly employed in builder motions for obtaining a filling build. Normally, however, a cam of this sort is arranged to act on a pivoted builder arm to deliver the traverse movement as previously noted, while the builder motion of the present invention incorporates no builder arm of the conventional type at all and uses the cam 19 simply as a source of oscillating motion. Accordingly, the shape of the oscillator cam l19 becomes a matter of convenience as employed in the present invention, so that its illustrated shape is purely representative and might be varied at will for supplying an oscillating motion suited to a particular instance being dealt with.
  • a slidably mounted yoke 39 is arranged in following relation thereat; this yoke 39 having a follower roll carried thereon at 40 to ride the outline of cam 19, and being hung from an upper slide rod 41 with a bias spring 42 extended therefrom to make certain that the following relation is always maintained.
  • the upper slide rod 41 is fixed in the main housing 10 at a disposition extending transversely of the builder shaft 17 and vertically aligned above the worm Wheel 27 (compare FIGS.
  • a lower slide rod 43I is similarly carried by the housing below the worm wheel 27, while the yoke 39 is offset to extend downwardly between the oscillator cam 19 and the worm wheel 27 for connection with a worm 44 that is rotatably and slidably disposed on the lower slide rod 43 in engagement with the worm wheel 27.
  • connection of the yoke 39 with the worm 44 is made through a bearing unit (as indicated at 45 in FIG. 3), so that the worm 44 remains rotatable on the lower slide rod 43 while being caused to oscillate axially in response to the motion transmitted by the yoke 39 from the oscillator cam 19; and the result of such axial oscillation is that the worm 44 acts additionally as a rack to oscillate the worm wheel 27 angularly about its axis, together with the cycling cam 28 carried thereon, while still being rotatable for acting in its usual character to rotate the worm wheel 27 and cycling cam 28.
  • the worm 44 is formed specially according to the present invention, as seen best in FIG.
  • FIG. 5 The nature of the cycling cam 28 that is assembled with the Worm wheel 27 for oscillation and rotation through the worm 44 as just described above, is illustrated in FIG. 5 with diagramming related to the showing in FIG. 6 of a representative filling bobbin build to be produced.
  • a lling bobbin characteristically requires a feeler bunch to be built first adjacent the base of the bobbin for signalling imminent exhaustion of the active shuttle bobbin during loom operation; then a main yarn package extending predominantly on the body of the bobbin; and nally, if an automatic loom battery is to be serviced, a tip bunch must be built in spaced relation above the main yarn package.
  • the illustrated cycling cam 28 is formed with operating segments a-b, b-c, c-d, and d-e, to accomplish each of these steps, plus a final operating segment e-a for recovery movement to complete the builder motion cycle.
  • the several dotted circles spaced about the contour of the cycling cam 28 in FIG. 5 represent the relative positions at the operating segment boundaries of the follower roll 31 through which the traverse movement is delivered to the slide member 32.
  • the start lof oper-,ations will commence rotation of the oscillator cam 19 as the input drive is delivered through shaft 13 and the gearing 15-16 to the builder shaft 17, and rotation of the oscillator cam 19 will in turn commence oscillation of the cycling cam 28 about its axis through the connection of the follower yoke 39 with the worm 44.
  • Such oscillation will cause a repeating fall and rise of the follower roll 31 along the operating segment a-b of the cycling cam 28 that is provided for building the feeler bunch as indicated in FIG. 5, and this repeating fall and rise will actuate the slide member 32 correspondingly to deliver the traverse movement in an extent and at a rate dictated by the mechanical proportions of the previously described operating elements through which the cycling cam 28 is oscillated in response to rotation of the oscillator cam 19.
  • the traverse movement would simply track itself at the same position so that no building displacement would be obtained along the bobbin barrel, and the builder motion is accordingly arranged for additionally actuating controlled indexing rotation of the worm 44 both at periodic intervals, to provide a letoff action comparable to that of the pick mechanism of conventional builders, and at selected intervals for supplementary indexing of the cycling cam 28 to bring its several operating segments successively into play with proper timing as the building operation progresses.
  • FIGS. 2 and 8 The arrangement to obtain periodic indexing rotation for letting olf is illustrated in FIGS. 2 and 8 as being operated from the previously mentioned lateral sprocket wheel 25 that is driven through the chain 20 from the builder shaft sprocket wheel 18, so that the operation proceeds concurrently whenever the oscillator cam 19 is being rotated.
  • the lateral sprocket wheel 25 is mounted on a stub shaft 49 that is supported by the main housing 10 to carry a bevel gear 5t) as well.
  • a mating bevel gear 51 is carried on a take-off shaft 52 that extends through bearing supports arranged in a sleeve portion 53 of an auxiliary housing plate 53 fitted on the main housing 10 and with an auxiliary housing cover 54 assembled thereon (compare FIGS. 8 and 9).
  • the yauxiliary housing sleeve portion 53' also supports a rotatable sprocket member 55 in concentrically spaced relation about the take-off shaft 52, and a sprocket chain 56 is extended from the sprocket member 55 to a sprocket 57 xed on the previously noted countershaft 48 at an end thereof extending to a supported disposition in a second sleeve portion 53" of the auxiliary housing plate 53 (compare FIGS. 2 and 9).
  • the extending end portion of the take-off shaft 52 has an outer cam plate 58 slidably keyed thereon with a bias spring 59 bottomed in adjacent retaining means 60 to urge the outer cam plate 53 toward the sprocket member 5S so that a tubular friction block 61 carried at the cam plate hub portion will be applied to cause rotation of the sprocket member 55 and thereby connect the take-olf shaft 52 to rotate the countershaft 48 through the chain 56 and sprocket 57.
  • the outer cam .plate 58 is only allowed, however, to shift at periodic intervals toward the sprocket member 55, in the above noted manner, by the arrangement of a cam roll 62 on the auxiliary housing plate 53 which ⁇ acts to maintain the outer cam plate 58 retracted against the force of the bias spring 59 during a portion of each revolution that it makes; and an inner cam plate 63 is nested with the outer cam plate 58 and made relatively adjustable thereon for setting the extent of the retra-cted positioning during each revolution (see FIGS. 9 and l0).
  • each of the cam plates 58 and 63 are circularly/ shaped and have a substantial circumferential portion thereof peripherally flanged (as indicated at 64 and 65 in FIGS. 9 to l2) at respective widths that will nest coextensively at a iirst camming width, and the remaining circumferential portion 66 and 67 of each cam plate 5S and 63 has a lesser respective width for nesting coextensively at ya second lesser -camming width; these rst and second camming widths being such that the outer cam plate 58 is displaced to its retracted position while the cam roll 62 is ridden by the flange portions 64 and 65 forming the irst camming Width and is released at the second lesser camming width for applying the friction block 61 to the sprocket member 55'.
  • the inner cam plate 63 is assembled at its nested position by clamping means 68 fitted with tightening screws 69 that allow adjustment of the cam plates 58 and 63 to a selected circular relation for presenting desired circular extents of the first and second camming widths to the cam roll 62 during each revolution.
  • the inner cam plate 63 may advantageously have an arcuate scale 7 El laid out thereon at a suitable calibration, such as in terms of the yarn count for the bobbins to be built, with a related aperture 71 and indicator marking '72 on the outer cam plate 58 to gauge the setting as illustrated best in FIG. l0.
  • the operating result of the above described mechanism is to drive the countershaft 43 periodically so that a periodic indexing rotation of the worm 44 is effected through the spur gear 47 that acts in turn through the worm wheel 27 to cause a periodic letofi ⁇ indexing of the cycling cam 28 concurrently with the previously mentioned oscillation resulting from the action of the oscillator cam 19, and thereby provide the progressive positioning or displacement of the traverse movement required by the building operation.
