Claims priority, application Great Britain September 27, 1949 6 Claims. (Cl. 19-159) The invention is concernedwith sliver-coiling apparatus for use in conjunction with such textile machinery as carding-engines, draw-frames, combers and the like from. which the treated fibres are delivered in the form ofa sliver which is customarily coiled into a cylindrical canor other receptacle preparatory to the next stage of treatment in the processing of the fibres. The object of the invention is to provide an improved form of coiling apparatus for use in the circumstances described, as an alternative to the known form of apparatus in which the coiling action is achieved by a precessional movement of the can or receptacle in which the sliver is received.

A sliver-coiling apparatus according to the invention comprisesa coiler guide element by which the uncoiled sliver is received, and means for imparting to said guide element'two'concurrent motions, i. e. a precessional motion by which the sliver is laid in a continuous series of coils, and an orbital motion whereby the position of each successive coil is progressively advanced along the orbit path.

The apparatus may comprise a coiler guide element constituted by two components having inclined guide passages traversed successively by the sliver, the first ofsuch components being revolved concentrically about a given axis (which may be the longitudinal axis of a cylindrical can), and the second component precessing upon an orbital path traced by the outlet of the passage in the first component, and the arrangement preferably being such thatthe outlet of the inclined nent' always coincides with the inlet of the inclined passage in the second component.

Alternatively, the apparatus may comprise a single inclined coiler guide subjected to the action of separate mechanisms respectively producing the concurrent precessional and orbital motions requisite'to deliver the sliver in a coiled formation of which each successive coil is displaced laterally in relation to the preceding coil.

In both the aforesaid forms of the apparatus the lead or displacement of one coil in relation to the preceding coil is measured by the arcuate distance travelled by the axis'of precessional rotation along the path of the orbital movement. If desired, such leadmay be made equal to the thickness of the sliver, in order to achieve a closely packed disposition of the coils in the can, and it can be varied by suitably regulating the relative angular speeds of precessional and orbital rotations.

The manner in which the invention is carried into effect is hereinafter more fully described with reference to the accompanying drawings. Fig. l of such drawings is a sectional elevation of one form of coiling apparatus, the section being taken on the vertical centre-line; Fig. 2 is a plan, partly in section, of the coiling apparatus seen without the upper cover and sliver-plate; and Fig. 3 is a horizontal section on the line IIIIII of Fig. 1. Fig. 4 is a similar view to Fig. 1, illustrating a modified embodiment of the invention.

The apparatus depicted in Figs. 1 to 3 includes a stapassage in the first compotionary frame of which a part is shown at 1 and which carries a two-part cover arranged to enclose the coiling mechanism. The part 2 of said cover is pivoted at 4 on the frame 1 and the part 3 of the cover is pivoted at 5 on the part 2, the arrangement being such that the. entire cover 2, 3 can be raised by a lip which forms the left hand extremity of the cover part 2 to reveal. the mechanism when desired. A similar lip which. forms the left hand extremity of the cover part 3' may be used'to lift the'cover part 3 independently of the part 2. A sliver guide 6 is supported upon the cover part 3. A conventional sliver-plate 7, which incorporates a trumpet-guide 8, is pivoted to the cover part 3 at 9. The sliver plate is provided with a lip by which it may be raised'independently of the cover parts 2 and 3. A catch 10 is also pivoted at 5 in such position that when the cover part 3' is raised said catch may be engaged behind a projecting part 11 of said part 3 for the purpose of supportingthe latter in its raised position.

The frame 1 also supports a bearing 12 for a vertical driving-shaft of which the upper extremity is. shown at 13. Said shaft 13 bears a fixed bevel gear 14 which meshes with a bevel gear 15 on a horizontal shaft 16. A second horizontal shaft 17 is geared to the shaft. 16 through pinions 18', 19, and'the two shafts respectively carry the calender rolls 2t), 21 which are thus rotated in opposite directions to deliver sliver fed through. the trumpet-guide 8 to the coiling mechanism. The shaft 16 is supported by bearing brackets 22 which are mounted on the frame 1, and the shaft 17 is supported by a bracket 23 which forms part of a lever 24 mounted with capability of movement about a vertical-axis on a stud 25which is carried on the frame. A spring 2b serves normally to urge the roll 21 into rolling'contact with the roll 20'. (For the sake of clarity, the me'mbers22', 23, 24, 25"and 26 are omitted from Fig. 1.)"

The coiling mechanism consists of the two part coiler guide and the means provided for its operation asbereinafter described. The guide comprises two

independent components

27 and 28, respectively providedwith inclined guide-passages 29 and 30 which extend between their upper and lower surfaces. The two passages 29'and 30 together constitute an' inclined duct through which the sliver delivered by the rolls 20, 21' is led to the can. of which the open top is indicated at 31.

The frame 1 supports a ball-bearing 320m which is rotatably mounted an annular gear-wheel 33. Said annulus 33' includes a ball-bearing 34 supporting a carrierplate 35, having a flanged lining sleeve or bushing. 352i upon whichis mounted the lower guide component 28. with capability of rotation relatively to the plate 35. about the eccentric axis X-X. Said plate 35 is itself. capable of rotation on the bearing 34 about the. vertical. axis Y-'Y, hereinafter referred to as the orbital axis. Studs. 3512 (one shown) support a cover plate 350 fromthe plate. 35 for rotation in unison with the latter. A pinion. 3'6, affixed to the component 28 meshes withan idler-gear. 37 which is fixed on a stud 38 rotatable in a bracket 39 carried by the plate 35; a second idler-gear 40 fixed on said stud 38 is arranged to mesh with the annular gear.- wheel 33, and this latter is driven through an idler. 41.

(Figs. 2 and 3) by a spur wheel 42 fixed on the. driving.

29 also intersects the axis X-'-X at the same'poi'nt. The

component 28 is capable of rotation about the axisX'X relatively to the component 27, between which latter" and the plate 35 a driving connection is provided'by'the" engagement of an off-set or projecting portion 43 of the component 27 in a recess 44 in said plate, and a boss 45 surrounding the lower extremity of the guide-passage 29 in the component 27 is rotatably mounted in a corresponding recess 46 provided in the surface of the component 23 about the upper extremity of the guide-passage 30. The axis XX is hereinafter referred to as the axis of precession.

An intermittent rotation of the upper guide component 27 about the orbital axis Y-Y is effected by means of a cam 47 keyed on the driving shaft 13 and arranged to actuate a bowl 43 mounted on the end of a lever 49 which is rotatably mounted on the component 27. A tension spring t), stretched between said lever 6? and fixed bracket 51, serves to hold the bowl 4% constantly in contact with the cam 47, and the intermittent angular movement of the lever 49 in the anti-clockwise direction (as seen in Fig. 3) is communicated to the component 27 by a free-wheel device incorporating a roller 52 mounted between the periphery of the plate 53 which is fixed to the component 27 and an inclined face 54 on the lever 49, the arrangement operating in known fashion to transmit anti-clockwise angular motion from the lever to the component 27, but to allow the lever freely to return under the spring 50, when the cam 47 turns to the inoperative position. The clockwise motion of the component 27 is positively prevented by a roller 55' mounted between the periphery of said plate 53 and an inclined face 56 on the fixed bracket 51.

It will be seen that as the sliver issues from the passage 30 of the component 28 it is laid in coils which owe their formation to the precessional motion of the component 28, and that the effect of the intermittent orbital movement imparted by the cam 47 to the component 27 is to traverse the rotational axis XX of the component 28 along an orbital path concentric to the axis Y-Y. By these means each successive coil of sliver is laid slightly in advance of the preceding coil being measured by the chordal length of the arc of the orbital path through which the component 27 is rotated at each rotation of the cam 47.

The embodiment of the invention which is illustrated in Fig. 4 differs from that already hereindescribed with reference to Figs. 1 to 3 to the extent that the coiler guide element comprises a single component to which the mechanism imparts a continuous combined precessional and orbital movement. In this case the guide element 57 is provided at the upper extremity of the inclined passage 58 with a flared mouth 59 capable of receiving a sliver delivered by the

calender rollers

20, 21, the lower end of said passage 58 being located above the cylindrical can 31 into which the sliver is to be coiled. Said element 57 is adapted for rotation on the ball-bearing 60 about the axis of precession XX, said bearings 60 being mounted on an annulus 61 (hereinafter referred to as the carrier annulus) which is itself mounted for rotation about the axis of orbital rotation YY, which latter axis coincides with the longitudinal axis of the cylindrical can 31.

The said carrier annulus 61 carries a peripheral gearring 62 and also carries a second bearing 63 on which is rotatably mounted a second annulus 64 (hereinafter referred to as the gear annulus) which is furnished with an internal spur gear 65 which meshes at one point with an external pinion ring 66 on the periphery of the sliverguide element 57. The gear annulus 64 is also furnished with an external spur gear 67 which meshes with a pinion 68 fixed on the vertical drive-shaft 13, rotation of which produces the precessional rotation of the sliverguide element 57 about the axis XX through the medium of the gear annulus 64.

The aforesaid peripheral gear-ring 62 on the carrier annulus 61 is arranged to mesh through the medium of a reduction train, comprising an idler 69, a pinion 70 loose on the shaft 13, and an internal gear-ring 71 on said pinion 70, with a pinion 72 mounted eccentrically on the drive-shaft 13. Said eccentric pinion 72 is fixed to a companion pinion 73 which is in mesh with a fixed internal spur gear 74 concentric with the drive-shaft 13. The eccentric pinion 72 is compelled to rotate by reason of the combined effect of its eccentric mounting on the drive-shaft 13 and the abutment of its companion pinion '73 with said fixed spur gear 74, and the resultant motion is transmitted through the reduction train 71, and 69 to the carrier annulus 61 imparting to the sliver guide element 57 an orbital rotation concurrent with the precessional rotation of the element 57 relatively to such annulus 61. The reduction ratio of the gear train 69, 76 and 71 can be altered to vary the relative speeds of orbital and precessional rotation and, by thus altering the point at which each coil is commenced by a fresh precessional rotation, it is possible to adjust the lead or overlap of successive coils.
