Definitions

  • This invention relates to the clearing of lint, fiy and the like foreign matter from the moving components of textile machinery, and is particularly directed to means for clearing the processing rolls of drawframes, spinning frames, roving frames, and the like.
  • the textiles or textile fibers are passed between pairs of rolls serving to draw out, attenuate, or otherwise effect the relationship between the processed fibers.
  • the rolls of the drawing and spinningfrarnes have a propensity for the collection of fly lint and the like material.
  • Stationary clearers have been employed, positioned adjacent these rolls so as to wipe the material accumulating on the surface of the roll. Notwithstanding the utilization of the stationary clearers, however, a condition termed eyebrowing frequently occurs when waste builds up in front of a clearer. Attempts have been made to eliminate eyebrowing by positioning suction ductwork behind the roll clearer so as to pick up these eyebrows.
  • the novel means implement the clearing of a roll as employed in the processing of textile fibers so as to prevent the accumulationv of eyebrows between the clearer member and the roll surface, thus minimizing maintenance by an operator, and serving to improve the quality of the yarn produced.
  • Another object of the invention is to provide an improved roll clearer for textile machinery in which the formation of eyebrows is prevented.
  • Afurther object of the invention is to provide improved roll clearing means in which the clearing members are substantially self cleaning, minimizing the required care of an operator.
  • a further object of the invention is to provide an improved clearer for the rolls of textile processing machinery in which the, clearer is substantially self adjusting with respect to the surfaces to be cleared.
  • an improved clearer comprising a clearer body member arranged adjacent the surface to be cleared.
  • a clearer body member Surrounding this clearer body is a flexible wiping sleeve formed of a resilient walled tube of rubber, neoprene or some other synthetic having desired clearing properties.
  • the interior dimension of the wiping tube or sleeve is such as to accommodate the body member with spacing between the interior wall of the sleeve and the body member permitting the sleeve to flex.
  • a sleeve retainer in the form of a channel-shaped plate is arranged over United States Patent 3,196,476 Patented July 27, 1965 the wiping sleeve to sandwich same between the sleeve retainer and the clearer body.
  • the sleeve retainer functions to shape the wiping sleeve to a desired contour, serving to billow same against the surface to be cleared.
  • Means mounting the clearer body and sleeve for limited rotation are provided in the form of a rotating journal extending from each end of the clearer body into a bearing block.
  • the bearing block in turn is slidably journaled in a bearing bracket on each end of the surface of the machine component to be cleared which in this case is a roll, thus providing sliding mounting means for the clearer permitting its displacement from the surface to be cleared.
  • the bearing block is coupled to the clearer body by means of a flexible walled energy storing coupling member in the form of a torsion sleeve extending over a coupling shoulder on the clearer body and over the bearing block.
  • Coupling sleeves are formed of a flexible material such as rubber or the like material.
  • This novel mounting bracket for the novel clearer member.
  • This novel mounting bracket slidably supports the clearer member at a desired angle with respect to the surface to be cleared so as to permit torsion buildup in the clearer member to result in displacement of the clearer member from the roll surface.
  • Another important feature of the invention resides in the utilization of the elastic coupling sleeve to provide the desired torsion coupling.
  • FIG. 1 is a perspective view of the novel clearer shown as mounted for use in clearing the top roll of a roll pair of a drafting roll stand;
  • FIG. 2 is a cross-sectional view taken on line 2-2 of FIG. 1, through the drafting roll and the novel clearer looking in the direction of the arrows;
  • FIG. 3 is a longitudinal cross-sectional view through the end of the novel clearer illustrating the details of the bearing and journal;
  • FIG. 4 is a schematic cross-sectional view similar to FIG. 2, illustrating the vector forces acting on the wiping sleeve.
  • FIG. 5 is a schematic illustration similar to FIG. 4 indicating the desired range of angulan'ty through which the clearer may be positioned with respect to the roll surface to obtain the desired results;
  • FIG. 6 illustrates the phases of movement of the-clearer with respect to the roll surface.
  • novel clearer assembly 10 is formed with a clearer body 11 surrounded by a flexible wiping sleeve 12 of a tubelike configuration.
  • Sleeve 12 is secured to body 11 by means of a sleeve retainer 13 which is of a channel-like configuration and is designed to sandwich a portion of the sleeve 12 between the body and the retainer 13.
  • Screws 14, or the like fastening 3 members are employed to secure retainer 13, body 11 in Operative relationship.
  • Body member 12 is formed of a trapezoidal cross-sec- .tion as best seen in FIGS. 4 and 5 with a relatively wide base 15, as opposed to the relatively narrow top 16, a substantially vertical rear wall 17 and an inclinedfront sleeve 12 and wall 18.
  • 1 Nose *20 is formed between base 15 and front wall 118 as viewed in the drawing, for a purpose to be made hereinafter moreapparent .i a I.
  • p Sleeve retainer 13 is formed of a channel-shaped crosssection as best seen in FIGS. 4 and '5, with atop wall adjoining front wall 21 to rear wall '22. Top wall is of a dimension such as to permit it to overlie.
  • Means mounting the clearer body 11. and sle'eve12 for limited rotation are provided by rotating journal 22 which is rotatably, received within bearing block 25 preferably between the clearer 10 and the roll R and a line parallel to the tangent.
  • the vertical axis through the clearer body 11 does not necessarily extend through the point of tangency. It will also 'be noted that the illustrated preferred range of angular positioning of the mounta ing axis of the'clearer 10 Withrespect to the roll axis is roll or'on a bottom roll.
  • the clearer location does not have to be limited to this range, and, may, in fact be utilized on a bottom section of the After mounting of the clearer with respect to the surface to be cleared, rotation of theroll with respect to the clearer sleeve 12 rot-ates the clearer body on itsrotating 7 journal'22a limited distance resulting in displacement of the clearer sleeve through the phases illustrated in FIG. 6.
  • Block '25 has a sleeve support 26 on one end'thereof'anda sliding mount for clearer body 11 and sleeve 12 in the form of sliding journal 27 on the other end thereof.
  • the force F acting in a direction a at right angles to the vectorA has a lever arm designated l7.
  • Forces A and B' acting thr-oughtheir lever arms a and b respectively, combine to form a moment which tends sleeve support 26 and the sliding journal 27 are separated by a bearing shoulder 28, as best seen in FIG. 3.
  • Torsion sleeve 29 is press fitiinto position and: securely to'rotate fthe clearer assembly in the counter-clockwise direction as indicated bythe' direction arrow applied to 'FIG. 4. This moment tends to wind the flexible walled coupling sleeve 29. 'The force A, however, along'withthe momentum' of the clearer components produced by the V wiping action .cause the clearer 10 to move away from engages knurled portion 21 and the surface; of sleevesupport 26 on bearing block 25.
  • the surface of support 26f is preferably formed with splines or the like projections.
  • a clearer supporting bearing bracket 30, as ,best seen in FIG. 1 is arrangedon each side of a novelclearer 10 r to support same with respect to .the rolls to be.cleared,
  • Bearing bracket 30 is formed of a sheet material such as steel or the like bent into a right-angle configuration with a horizontally extending supporting shoulder 31, and a 1 vertically extending'bearing plate 32.
  • the bearing slot 33 is formed in bearing. plate 32 receiving sliding journal H 27.
  • the bearing plate additionally bears against bearing
  • the novel clearer 10 is arranged with respect .to the surface to be cleared so that the wiping sleeve 12 bears against the moving surface.
  • the clearer 10 is shown as positionedwith respect to the'rolls R so as to function as a top roll clearer.
  • the clearer 10 To insure vibration, the clearer 10 must be located at the p'roperangle with respectto .the roll R. The limits of this angle asshownby the shaded area in FIG. 5, as
  • FIG. 6E It will be noted from FIG. 6E that wiping sleeve 12 moves slightly forward of its original starting position due to its momentum resulting from the released stored elastic forces. This produces abufieting action on the roll surface tending to .dislodge any eyebrowing not displacediby the previously described movement of the clearer.
