Definitions

  • This invention relates to a textile handling arrangement, and more particularly to an improved apparatus for use in the drafting of a running length of textile fibers.
  • a further feature is the cleaning of the bottom rolls of two succeeding pairs of rolls by a bridge device which serves also to support and guide the fiber mass between the two pairs of rolls.
  • Still a further feature is the provision of an improved, multiple function cradle assembly and bridge element subassembly which eifects roll cleaning and improved fiber support and control between spaced drafting rolls, as well as apron cleaning and improved apron tracking, and cradle alignment.
  • a multiple function fibersupporting and guiding bridge element is disposed between and carried in rubbing engaging relation on the bottom rolls of two succeeding pairs of drafting rolls, being preferably incorporated in an improved cradle arrangement including an apron-supporting and guiding element connected to the bridge element.
  • the novel bridge element serves two basic functions, one of which is the support and guiding control of the fibers between the respective succeeding pairs of rolls, particularly in the drafting zone immediately preceding the front rolls of the respective adjacent pairs of rolls, and the second basic function being the cleaning of the fiber carrying peripheral portion of the two bottom rolis on which the bridge element lies.
  • the bridge element serves to clean the exterior surface of the cooperating apron during the passage of the apron thereby along its fiber-control run.
  • the apron is preferably guided about a combination roll-and-apron-cleaning and apron-positioning element disposed in guiding relation within the apron periphery and engaging in cleaning relation both the apron interior and the respective aproncarrying roil surface.
  • FIGURE 1 is a perspective view of a single drafting assembly incorporating one embodiment of the present invention.
  • FIGURE 2 is a longitudinal section view of the arrangement of FIGURE 1.
  • FIGURE 3 is an exploded view in perspective of the novel cradle arrangement of FIGURE 1.
  • FIGURE 4 is a longitudinal section view of a modified and preferred embodiment according to the invention.
  • FIGURE 5 is an exploded view of the preferred cradle assembly of FIGURE 4.
  • FIGURE 6 is an inverted view in perspective of the upper element of the cradle assembly of FIGURES 4 and Referring nof to the figures of the drawings, in each of the embodiments the invention is shown as applied to a drafting system incorporating three parts of succeedingly faster-driven drafting rolls, including back rolls 11, 13, middle rolls 15, 17, and front rolls 19, 21. Also, in each of the preferred embodiments, an apron is carried about the surface of roll 15 and is guided through a reduced radius nose zone adjacent roll 19 through the medium of a roll-and-apron-cleaning and apron-guiding element 25.
  • the cleaning and guiding element 25 is connected to a multiple purpose bridge element 27 which extends be tween and rides, preferably in substantiaily floating rela tion, on the peripheral surface of each of preferably smooth-surfaced roll 17 and front roll 21.
  • the elements 25 .and 27 are removably-connected together through the medium of two side spacer brackets 29 which are adjustably-secured to the respective cleaning-and-controlling elements 25, 27 through the medium of screws or studs 31, 33 engaging in adjustment slots 29a, 2% formed in the spacer bracket.
  • the relative position of securing screw 33 in the slot 29b will determine the spacing between the adjacent interfacing apron-guiding surface 25c of element 25 and apron-andfiber-guiding surface 270 of element 27.
  • the slot 29a permits iongitudinal adjustment of the element 25 with respect to the element 27, thereby permitting closer or further apart spacing of the roll 15 with respect to the roll 19.
  • the element 25 may be either fixed in longitudinal position with respect to the element 27 or may be in floating longitudinal relation relative arsaees thereto.
  • the apron-guiding element 25 is provided with means in the form of side shoulders 25d which extend about the opposite ends of the boss portion of the roll 15, in order to impart lateral stability to the assembly 25, 2'7, 29 with respect to the rolls 15, 17, and the passage of the fiber mass F therebetween. Lateral stability for the apron 23 is provided by the side spacer bracket elements 29.
  • this element has a roll-engaging concave cleaning surface 25a, an aprOn fiber-control-run-guiding surface 25c, a reduced diameter nose end 25:) and a return surface 25 thus guiding the apron in a tapered path extending from the roll 15 to and from a nose position adjacent the roll 19.
  • the cleaning and fiber control element 27 is, in this embodiment, illustrated as a block having two oppositely facing concave roll-engaging cleaning surfaces 27a, 27b, with an intermediate apron-engaging-and-guiding and fiber-mass-supporting-and-controlling surface 27c which entends from closely adjacent the roll 17 to the surface of front roll 21.
  • the fiber-supporting-and-controlling surface 27c is preferably somewhat convex, as by forming thereon a chamfer or a long smooth convex curve at or closely adjacent the entrance end thereof, as indicated at 27], in order to aid in feedthrough of the fiber mass between this surface and the adjacent fiber-control run'of the apron 23.
  • the curvature and positioning of the surface 27c, 27 and the adjacent interfacing surface 25b be such that the apron-fibercontrol run will be guided upwardly from the point of tangency between the rolls 15 and 17, when the fiber mass F is passing therebetween, as shown more particularly in FIGURE 2, in order to afford what has been found to be the best degree of control of the fibers in this zone.
  • an undercut 27g at the entrance end of the concave surface 27a, thus providing a space of from approximately five to twenty-five thousandths inch depth and approximately one-eighth to one-quarter inch in length.
  • This is of material value in preventing the protruding fibers in the fiber mass from being impinged between the roll periphery and the element thus causing the entire mass of fibers to follow thereabout as the fiber mass passes from between the nip formed between the apron and the roll 17.
  • the apron 23 is itself of material importance in moving the fiber mass F past this critical zone and along the further control path extending between the apron and the surface 27f, 27c of the element 27.
  • the element 27 serves as a multiple-function element in which the concave surfaces 27a, 27b, not only stabilize the entire system 25, 27, 29, relative to rotation about the axis of either of rolls 15 or 17, but also" serve to clean the rolls 17 and 21 through their rubbing engagement therewith, the element serving, through its fiber-supporting-and-control surface 27 2%, the additional and most vitally important function of supporting and controlling the passage of the fiber '4 mass F as it passes between the rolls 15 and 17 and the rolls 19, 21.
  • the element 27, through its extended surface 27c serves to support and control the path and passage of the fiber mass F in the important draft zone immediately preceding the nip of the rolls 19, 21.
  • FIGURES 4-6 there is shown a preferred modification of the invention, incorporating elements and 127 that correspond in function and mode of operation to elements 25 and 27 of the preceding described embodiment.
  • the eiements are removably interconnected through the medium of side ears 129 formed on the element 125 and extending down about the side of the elements 127.
  • the side ears 129 have detents 12% formed thereon which engage with pocket recesses 127i formed in the side walls of the center web portion of the cleaning and control element 127.
  • detent and socket connection is shown with the detent 12% formed on the ears 129 and the socket recesses 127i formed on the element 127, it will, of course, be apparent that this may be reversed, and that other alternative methods of connection may also be employed, as for instance by passing a pin through the cars 129 and through a bore which may be formed in the element 127, or by employment of screws or other suitable connecting or securing means.
  • the socket recesses 1271' are preferably longitudinally elongated in a direction parallel to the surface 1270, so as to permit longitudinal self-adjustment of the element 125 with respect to the element 127, and thus permitting self-adjustment to accommodate varying tolerances between the rolls 15 and 19 or variations in diameter of the roll 15, or variations in setting between the rolls 15 and 19.
  • Precisely complementary socket and recess connections may, however, of course be employed if desired and if no self-adjustment is necessary for a given instance of use.
  • the cleaning and controlling bridge element 127 in this embodiment has two cantilever legs 127m, 12711, which are connected by a central web section, and the entire element 127 may be formed of a material, such as Delrin, which is sufficiently elastic, though dimensionably stable, to permit the springing in of the legs 127m, 12711, for insertion and removal of the element 127 between the rolls 17 and 21.
  • this preferred element 127 differs frorn'the insertion of the preceding described bridge element 27 in the embodiment of FIGURES l3 in that the bridge element 127 may be snapped into and out of position, whereas the element 27 must be inserted into position by first lowering such between the reduced diameter portions of the rolls 17 and 21 and then sliding such laterally sideways to a position engaging between the boss portions of the rolls 17 and 21. It will be apparent that the entire preferred embodiment of FIGURES 46 is more easily and quickly assembled and disassembled than the embodiment of FIGURES 1-3 illustrating the basic principles of the invention.
  • FIGURES 4-6 is substantially identical to that of the first-described embodiment of FIGURES 1-3. Similar reference numerals are given to similarly functioning and shaped portions of the elements 125 and 127 as are given to the elements 25 and 27 of the preceding embodiment, with the corresponding portions of elements 125 and 127 numbered in the 125 and 127 series, whereas the preceding embodiment portions of the elements 25 and 27 are numbered in the 25 and 27 series.
  • the fiber control surface 270 or 1270 of the element 27 or 127 may have formed thereon a tapered fiber-condensing groove, if desired.
  • the element 27 or 127 or both elements 25 or 125 and 27 or 127 may be laterally traversed transverse to the direction of the fiber flow path as by a traverse rod, if desired, rather than being maintained against substantial transverse lateral movement as in the two illustrated embodiments. Accordingly, it is to be understood that the invention is not to be limited by the particular illustrative and preferred embodiments disclosed herein, but onl by the scope of the appended claims.
