Definitions

  • An adjustable support for at least one of the feed rolls of a stuifer crirnper including a shaft carrying one of said rolls or carrying a bracket in which one of the said rolls is journalled.
  • the shaft is journalled in at least one bushing having an eccentric inner bearing surface and the shaft carries an eccentric end bearing portion journalled in said bearing surface.
  • the eccentricities of the end bearing surface of the shaft and of the inner bearing surface of the bushing are the same and the shaft and bushing are independently adjustable for varying the position of the axis of said shaft with respect to the axis of the bushing.
  • the double eccentric mounting permits the axis of the shaft to be adjusted both horizontally and vertically into any given position.
  • This invention relates to a stuffer crirnper having feed rolls for feeding yarn into the crirnper for crimping therein and more particularly to an adjustable mounting for such feed rolls by which the parallelism of their contacting surfaces can be accurately adjusted and maintained.
  • An object is to provide a simple and accurate adjusting means of the above type which can be applied readily to existing machines.
  • Another object is to provide a simple and convenient means for adjusting the feed roll support to compensate for wear of the bearing surfaces and for thereby increasing the useful life of the parts.
  • one of the feed rolls is assumed to be mounted for rotation in fixed bushings.
  • the other feed roll is supported by a shaft or journaled in a bracket supported by a shaft one end of which is mounted concentrically and the other end of which is eccentrically mounted in an eccentric bushing.
  • This provides a double eccentric by means of which the axis of the shaft can be adjusted to any desired angle within the range of movement of the eccentrics so as ice to bring the contracting surfaces of the rolls into parallelism in both the horizontal plane and in the vertical plane.
  • This is to be distinguished from a single eccentric mounting which would permit movement of the axis of the shaft in a circular path only.
  • FIG. 1 is a partial front elevation of a stuffer crirnper embodying the invention
  • FIG. 2 is a vertical section taken on the line 2--2 of FIG. 1 showing the eccentric bushings.
  • FIGS. 3, 4 and 5 are diagrams illustrating three different adjusted positions of the parts.
  • FIGS. 3a, 4a and 5a are diagrams illustrating the different angular positions of the axes of the shaft produced by the adjustments of FIGS. 3, 4 and 5 respectively.
  • the drawing shows a housing 10 forming a crimping chamber mounted in a support block 11.
  • a pair of feed rolls 12 and 13 are disposed be ow the housing 10 in a position to feed a yarn 14 into the crimping chamber.
  • the feed roll 12 is mounted on a shaft 15 which is journalled in bushings 16 in a bracket 17 carried by the block 11.
  • the !feed roll 13 is mounted on a shaft 18 journalled in bushings 19 in a bracket 20 which is mounted on a shaft 21.
  • the shaft 21 is mounted concentrically at one end in a bore 22 in a flange 24 of the block 11. At its other end the shaft 21 is reduced in diameter to form a bearing area 25 which is eccentric with respect to the axis of the shaft 21.
  • This bearing area 25 is journalled in an eccentric bearing surface 26 of a bushing 27 having an outer periphery 28 which is mounted for rotational adjustment in a flange 29 carried by the block 11.
  • the eccentricity of the bearing surface of the bushing 27 is the same as the eccentricity of the bearing area 25 of the shaft 21 with respect to the axis of the shaft 21.
  • the feed roll 13 is held in feeding engagement with the yarn 14 by a cord 32 one end of which is secured to the bracket 17 and which extends around a roll 33 on the bracket 20 and returns over a roll 34 on the bracket 17 and carries a weight, not shown, by means of which the rolls are held in predetermined pressure engagement with the yarn.
  • the rolls are geared together by gears 35 and 36 for operating at the same peripheral speeds and are driven by suitable means, not shown.
  • the bushing 27 is provided with a flange 46 which has a series of marks 40 thereon to facilitate adjustment and resetting and an adjusting pin 41 may be provided for insertion in suitable holes in the bushing flange 46 for manual adjustment of the bushing.
  • the flanged portion 46 of bushing 27 is clamped against the outer surface of flange 29 by means of a clamp element 44 held in position by a screw 45.
  • the shaft 21 may be provided with a screw driver slot 42 in its exposed end for adjustment and may be secured to the bracket 20 in set position by set screws 43.
  • FIGS. 3, 4 and 5 illustrate three possible adjustments of the eccentric bushing 27 and of the shaft 21 in the bushing.
  • the bushing 27 is set so that the center B of the eccentric bearing surface is directly below the center A of the outer peripheral surface of the bushing
  • the shaft is set so that its center C is directly above the center B of its eccentric bearing portion 25.
  • the point C thus coincides with the point A and the shaft is centered with respect to the outer peripheral surface of the bushing 27.
  • the axis of the shaft coincides with the axis of the outer peripheries of the bore and bushing.
  • This position of the shaft in indicated in FIG. 4a wherein D represents the center of the bore 22 and A the center of the outer periphery of bushing 27, and C the axis of the shaft 21.
  • FIG. 3a illustrates the angular shifting of the axis on the shaft 21 produced by this adjustment.
  • the position of the shaft 21 in the bore 22 does not change.
  • the point D remains fixed, and the line DA represents the axis of the outer periphery of the bushing 27, and the axis of the shaft 21 has been shifted to the line D-C.
  • the axis of the feed roll 13 remains parallel to the axis of the shaft 21 whether the shaft 21 supports the bracket 20 or supports the feed roll directly.
  • the line D-C can be considered to represent the axis of the feed roll 13.
  • the axis of the feed roll 12 is fixed and would be parallel to the line DA due to the construction of the machine. It is thus evident that the respective axes of the feed rolls can be angularly adjusted between the positions illustrated in FIGS. 3a and 5a in order to compensate for any irregularity in grinding of the feed roll surfaces or any mechanical displacement of the parts due to wear or distortion.
  • the fit of the shaft in the bore 22 usually provides for suflicient angular movement to accommodate the above described adjustment.
  • An adjustable support for a roll comprising a shaft by which said roll is supported, a member carrying a bushing in which said shaft is journalled, said bushing in which said shaft is journalled, said bushing having a cylindrical outer periphery mounted in said member, and an annular inner bearing surface eccentric with respect to said outer periphery, said shaft having an end bearing portion eccentric with respect to the axis of said shaft, said end portion being seated in said inner bearing surface of said bushing, said bushing and shaft being independently adjustable angularly for varying the position of the axis of said shaft with respect to the center of said bushing, said roll being journalled in a bracket and said bracket being mounted on said shaft for swinging movement about the axis of said shaft, and means for fixing said bracket to said shaft in the various adjusted positions of said shaft.
  • An adjustable roll roll support as set forth in claim 1 including a second roll and bearing means positioning said second roll to contact the surface of said first roll to form a bite therewith, said eccentric adjusting means being adapted to adjust the parallelism of said contacting surfaces.
  • An adjustable roll support as set forth in claim 3 including a stulfer crimper having a crimping chamberdisposed to register with the bite of said rolls for receiving a yarn therefrom.
  • An adjustable roll support as set forth in claim 1 in which said shaft is journalled in a pair of spaced bearings in said support, one of said bearings having ,a fixed axis, and in which said bushing constitutes the other of said bearings, whereby said adjustment shifts ang'ularly the axis of said shaft.
