Definitions

  • a spindle mounting for textile winding apparatus having improved vibration characteristics comprising a bearing assembly which engages the main frame at two spaced points through non-oil damped resilient means, the spaced points optionally being positioned so as to minimise spindle tilt.
  • This invention relates to Winding apparatus for filaments or yarns, and in particular to winding apparatus having a spindle on which the package is formed, or a group of such spindles, being driven by frictional contact of a part thereof with a continuous tape, which tape is driven by a motor, having each spindle rotatably mounted on the main frame of the winding apparatus so as to extend vertically upward from mounting, the tape-engaging part of the spindle being located between the package and the main frame, and having an associated yarn guide, for example a conventional ring and traveller, being reciprocated in a direction parallel to the rotational axis of the spindle.
  • an associated yarn guide for example a conventional ring and traveller
  • the lay of the filaments onto the package being wound is in a predetermined manner, such that a stable package is formed (with no tendency for the filament to slough off the package, or the package to disintegrate), and so that there is uniform packing density of the filament within the package.
  • vibration of the winding apparatus One source of variation in the manner of lay of the filaments is vibration of the winding apparatus. In addition vibration will cause the spindle mountings to become deformed or worn, causing the performance of the spindles to become erratic.
  • each spindle used in apparatus of the kind specified is mounted at an intermediate point and at the foot of the spindle in a journal bearing and a footstep bearing respectively.
  • the latter bearing is generally carried in an insert tube, in a bolster, having a certain amount of flexibility and has associated therewith provision for oil damping.
  • winding apparatus of the kind specified includes a mounting for each spindle comprising a bearing assembly which is arranged to engage the main frame of the winding apparatus at two spaced points through non-oil damped resilient means.
  • the spindle dimensions are such that the aforesaid two points are positioned with respect to the tape engaging part of the spindle so that spindle tilt is minimised.
  • the resilient means comprises two resilient members, although it is to be understood that the invention is by no means limited in this way.
  • Resiliently deformable plastics materials such as polyurethanes, are especially useful for forming the resilient members as many of these exhibit suitable rebound resilience.
  • the materials exhibit rebound resilience less than (Rebound resilience and its measurement are discussed at page 98 of Engineering Design in Rubber by Payne and Scott, published by MacLaren.)
  • each relief commences approximately halfway along each long side and extends at an angle of 10 to the long side.
  • each member should be situated equidistantly from the tape engaging part of the spindle. If the stilfnesses of the resilient members are not substantially identical then, to prevent tilt, each member should be positioned at a different distance from the tape engaging part of the spindle depending on the relative stiffnesses of the two members.
  • the thrust pad In addition to the bearing assembly and the resilient members, it may be necessary to provide a thrust pad at the base of the spindle, to support the weight of the spindle, and to rovide oil lubrication at this point such that it will lubricate the thrust pad and the bearing assembly.
  • the thrust pad does not need to be flexibly mounted or to be fitted with an expensive and troublesome oil damping arrangement.
  • the present invention enables a shorter bolster to accommodate the spindle below the main frame than would otherwise be required and, since, in this case, the thrust pad will be a shorter distance from a nodal point of vibration, the wear on the thrust pad will be reduced.
  • a spindle blade is provided with a whorl 11 having a tape engaging Zone 12 and a bobbin housing 13 and is mounted for rotation in a lower bearing 14 and an upper bearing 15, spaced apart by a spacer 16 and located in a bearing housing 17.
  • an upstanding hollow protrusion 18 Between the spindle blade 10 and the whorl 11 is an upstanding hollow protrusion 18 from a bolster 19, which bolster 19 is fastened to the main frame of a winding apparatus (not shown).
  • the protrusion is spaced apart from the whorl 11 but engages the bearing housing 17 through a lower annular resilient polyurethane member 20 and an upper annular resilient polyurethane member 21, the members 20 and 21 having a relieved rectangular cross-sectional profile such that they both have the same stiffness and being arranged to support the bearing housing 17.
  • the bearing housing 17 and resilient members 20 and 21 are held within the protrusion 18 by a retaining washer 22.
  • the relative dimensions of the parts are such that the tape engaging zone of the whorl 12 is positioned symmetrically intermediate between the resilient members 20 and 21.
  • the bearing housing 17 extends into the bolster 18 and a thrust pad 23 is positioned in the lower part of housing 17, into which pad 23 the lower end of the spindle blade 10 sits.
  • the lower part of the bolster 18 is filled with a lubricant 24, which may be drained by removal of a plug 25 in the lower part of the bolster 18.
  • a brake pad 26 is supported on the bolster 18 such that, on operation of a simple mechanism (not shown), the pad will be forced against the lower end of whorl '11 to slow or stop the spindle when required and a safety device 27 is provided to prevent the spindle whorl 11 from rising too far in operation.
  • the upstanding protrusion 18 and the bearing housing 17 may be coated with nylon 28 to reduce fretting corrosion between the polyurethanes and the metal surfaces.
  • the polyurethane bushes can be bonded to the protrusion and the bearing housing to reduce fertting corrosion.
  • journal bearing consists of two spaced apart bearings.
  • each relief commences approximately half-way along each long side of the respective rectangle and extends at an angle of 10 to the long side.
  • Winding apparatus comprising: a fixed, verticallyextending, tubular bolster; a vertically-extending, tubular bearing housing disposed in said bolster and radially spaced therefrom; bearing means carried within said bearing housing including a first bearing disposed within the upper portion of said housing, a second bearing disposed at a location spaced below said first bearing, and a nonoil-damped thrust pad disposed in the lower portion of said housing; a spindle mounted for rotation within said bearings and resting on said thrust pad, the upper portion of said spindle projecting out of said bolster; a whorl secured to said upper portion of said spindle and extending downwardly over said bolster, said whorl having a tape-engaging drive surface disposed intermediate said first and second bearings; and two spaced-apart annular resilient members extending around said bearing housing and supporting the latter within said bolster, one of said members being disposed at the level of said first bearing and the other of said members being disposed at the level of said second bearing.
  • Winding apparatus as in claim 7 including means disposed below said second bearing for securing said bolster to a winding apparatus.
