Definitions

  • This invention relates to a machine for removing trash and foreign matter from fibrous material. More particularly it relates to a machine for removing trash from cotton and other textile fibers.
  • Another object of this invention to provide an improved machine that will clean cotton fibers more efficiently. Another object is to provide such a machine in which more efiicient cleaning is accompanied by a reduction in the amount of fibers lost through various causes. A further object is to provide a fiber cleaning machine having nonloading rolls that retain no fibers on their surfaces. Still another object is to provide a fiber cleaning machine capable of separating trash from good fibers without causing some of the fibers to be lost in the trash chamber.
  • a conventional fiber cleaning machine having feed, transfer, and cleaning rolls is modified by providing a specially designed nonloading roll between the feed rolls and the cleaning cylinder, two sets of grid bars, one of which is specially designed to permit separation of trash only from the fibers on the cleaning cylinder, and a novel air doffing and circulation system.
  • FZGURE 1 represents a schematic elevation of the cleaner in section, of one embodiment of the invention.
  • FIGURE 2 is a fragmentary isometric view of the nonloading feed roll used in the apparatus
  • FIGURE 3 is a detailed illustration of the tooth construction and arrangement used on the nonloading eed roll
  • FEGURE 4 is a schematic view illustrating the tooth relationship of the nonloading roll and the cleaning cylinder
  • FIGURE 5 is a schematic sectional view of the first cleaning section of the apparatus of this invention.
  • FIGURE 6 is a partial schematic sectional view of the apparatus of FIGURE 1 showing a modified air circulation system.
  • the machine comprises a housing 1, having a plurality of openings and parts in its walls for the purposes of feeding fibers to be cleaned, entry and exit of air, and removal of trash and cleaned fibers.
  • a housing having a plurality of openings and parts in its walls for the purposes of feeding fibers to be cleaned, entry and exit of air, and removal of trash and cleaned fibers.
  • At one end of the housing there is "ice an opening 2 for admitting a mass or batt of fibers (not shown) to feed table 10.
  • This batt after being placed on table it is manually pushed forward to engage coacting feed rolls 11 and 11a.
  • Feed rolls 11 and 11a which may be smooth or with roughened surfaces, rotate in the direction indicated to advance the cotton to a unique nonloading toothed feed roll 12 which is one of the novel features of the invention.
  • This nonloading roll shown in detail in FIGURE 2, is mounted in parallel, spaced relationship to feed rolls 11 and Ho, combing roll 13 and fiber carrying cleaning cylinder 14.
  • Roll 12. is covered with a specially shaped two-pointed toothed wire 15.
  • the wire is installed along the longitudinal axis or" the roll rather than spirally wound, as is conventional. Adjacent rows of teeth are located so that the points are in staggered relationship to each other. It has been found that the optimum tooth density for processing cotton fibers to be from to points to the square inch, with the teeth along the same longitudinal axis being about 15 points per lineal inch.
  • the tooth 15 is preferably double pointed, as shown in FIGURE 3, with a height of about inch and a spacing of about & inch between adjacent teeth.
  • the longitudinal rows of teeth are spaced about inch apart.
  • Other tooth dimensions and densities can be substituted for processing other type fibers.
  • coacting combin roll 13 serves to partially loosen the tufts and arrange the fibers parallel to one another.
  • Roll 13 is a conventional liclcerin-type roll covered with spirally wound saw tooth wire 50. It rotates at about one fourth of the peripheral speed of roll 12.
  • the advancing fibers on roll 12 are transferred to cylinder 14, which is also a conventional lickerin-type cylindcr spirally wound with forwardly inclined saw-tooth wire 16 to provide approximately 60 points per square inch.
  • Cleaning cylinder 14 is 2 to 4 times the diameter of and has a peripheral speed of about to times that of roll 12.
  • a nonloading roll diameter of 6 inches rotates at a speed of 20 r.p.m., and a cleaning cylinder diameter of 14 inches, rotating at a speed of 1000* r.p.m., have been found satisfactory. Because of the big difference in peripheral speeds and the unique holdback action of nonloading roll 12, the fibers are transferred to roll 14 in an extremely thin, loose web that facilitates cleaning.
  • baffles 19 which are directly fastened to bars 18 and are disposed angularly outward in the direction of rotation of cylinder 14 (FIGURE 5), cause the fibers to be separated from the trash and returned to the teeth of cylinder 14. It is assumed that the air currents that exist in the area between adjacent bafiles and bars are responsible for this fiber reclaiming action.
  • the trash that is ejected falls into waste compartment 20 and container 21 which is removable by means of handle 21a.
  • the partially cleaned fibers on cylinder 14 are doffed from the cylinder by means of an air stream having about twice the velocity of the peripheral speed of cylinder 14.
  • This air stream comes into the machine through openings 3, 23, and 24 in housing 1 and thence through nozzle 22 which is specifically designed to direct the air against cylinder 14 at an angle of 45 degrees to a tangent drawn to the cylinder at the point Where the air stream impinges on the cylinder as it enters chamber 28.
  • the dofiing air thus first impinges directly on the surface of the cylinder and then is deflected outward across the saw-tooth wire.
  • the air more eifectively removes the fibers from the cylinder surface and from the teeth than is achieved by conventional methods of directing either negative or positive pressure air tangent to the cylinder or the saw teeth.
  • the air passing through openings 23 and 24 also serves to reclaim any fiber that may have escaped through bars 18 by conveying these fibers onto cylinder 14.
  • the commingled dotfing air and fibers flow onto rotating suction cage condenser 25 which is a perforate cylinder covered with 40 to 100 mesh screen material.
  • the fibers are retained on the screen surface, while the air passes through the screen to exhaust fan 26, driven by electric motor 27 or other suitable means and thence to the exterior of the machine in a manner that will be described later.
  • Chamber 28 is designed in a manner to cause turbulence in the air flow which results in the fibers and remaining trash being thoroughly mixed prior to impinging on condenser 25, where the fibers form a thin web.
  • the web is dotted from the condenser by coacting nonloading roll 29 which is of the same construction and function as previously described roll 12.
  • the aforementioned mixing that occurs in chamber 28 changes the spatial orientation of the fibers and remaining trash with respect to each other and with respect to cylinder 14, thus exposing new surfaces for cleaning and further improving the cleaning efiiciency of the machine.
  • Teeth 16 on cleaning cylinder 14 remove the fibers from roll 29 and subject these fibers to a cleaning action against triangular bars 51 whereby practically all of the remaining trash commingled with the fibers is removed to fall in dead air waste box 30 and removable container 31 with handle 31a.
  • Roll 29 and condenser 25 are enclosed by suitable partitions 52, 53, 54, and 55, except for a small opening 47, which retain the trash in chambers 20 and 30, thereby preventing redeposition of the removed trash onto rolls 14 and 29 and condenser 25. It has been found unnecessary to use fiber reclaiming batfies 19 or bars 51. However, such bafiles may be used if desired.
  • air is aspirated at high velocity by means of fan 26 through open ing 32 and nozzle 33 at an angle of 45 degrees to cylinder 14 to doff the fibers from cylinder 14 in a manner similar to the dofiing action at nozzle 22.
  • Chamber 34 formed by partition 35 and sidewall 56, provides a reservoir that serves to equalize the pressure and air flow across the width and length of nozzle 33.
  • the dotted fibers flow through duct 36 into chamber 37 which is enclosed by walls 38, 39, 40, and 41 and sidewall 57.
  • the fibers col lect on the surface of a fine mesh screen 42, while the air is exhausted through the screen by blower 26 to the exterior through opening 43.
  • the apparatus has a novel efiicient air circulating system that enables the same air to be used for conveying and dofiing both cleaning sections.
  • air enters the machine at inlets 3, 23, and 24, passes through constricted nozzle 22 to condenser 25, through the condenser to an interior opening 44 that leads into duct 45 mounted on the exterior of the machine. Dust 45 is connected to opening 32 leading into chamber 34 and associated dotfing nozzle 33. Thence the air and com veyed fibers progress into fiber collecting chamber 37.
  • the air passes through screen 42 to the exhaust fan 26 and hence to the atmosphere through opening 43. Simultaneously, air from outside the machine is drawn through opening 46 into chamber 30.
  • opening 47 located between partitions 52 and 53 and serves to aid roll 29 in dotting condenser 25.
  • the aforementioned screen 42 removes all fibers and thereby eliminates the need for an external system for filtering the air as is required by conventional cleaners.
  • Opening 43 has a slide valve 48 for adjusting the size of the opening to regulate the amount of air flow for optimum performance.
  • FIGURE 6 illustrates a modification of the air circulating system that may be used.
  • duct 45a from condenser exhaust 44 leads directly to chamber 37 through opening 49 located above screen 42.
  • a sliding valve (not shown) over opening 49 controls the ratio of air sucked in by fan 26 from chamber 37 and duct 45a.
  • air from outside of the machine is pulled in through openings 23 and 24 of FIGURE 1 (not shown in the partial view of FIGURE 6) and 32 and 46.
  • Other air circulating systems, such as separate blowers (not shown) attached to openings 44, 46, 32, and 43 can be used if desired.
  • FIGURES 1 and 6 Not shown in FIGURES 1 and 6 are the means by which rolls 11, 11a, 12, 13, 14, and 29 and condenser 25 are driven. These driving means do not constitute part of the invention.
