Definitions

  • ABSTRACT Apparatus for removing trash from carded fibers includes a plate portion conforming generally to card clothing on the main cylinder, means for positioning the plate portion in superposed spaced relation to the card clothing on the main cylinder between the means feeding fiber to the main cylinder and the doffer, and a passageway defined at least in part by the plate portion permitting removal of trash therethrough responsive to centrifugal force imparted to the trash by the main
  • the tendency has been to retain this from area of the main cylinder as closed as possible in order to confine the fibers and air currents occurring at that area adjacent the main cylinder.
  • a tendency has been observed for short fibers and trash to accumulate and build up between the cylinder and the arches causing choking.
  • Use of the apparatus illustrated herein has been found to reduce any tendency toward choking, as well as blow out of fibers.
  • the top front plate is set closer to the main cylinder than is the carding means further accentuating the opening thus formed between the plate and the carding means for trash removal.
  • Trash is any undesirable material which is advantageously removed from the carded fibers and includes the coarse pepperlike material, such as leaf and hull particles, which occurs in cotton laps and webs, as well as fly and short fibers and the like. It has been found that the coarse particulate matter is largely removed by the first-mentioned opening between the top front plate and the carding means, while short dirty fibers, fly, some particulate matters and the like, are removed at the last-mentioned opening between the top front plate and the front door plate.
  • FIG. 1 is a perspective view illustrating a carding machine having apparatus for removing trash constructed in accordance with the present invention
  • FIG. 2 is an enlarged longitudinal sectional elevation illustrating apparatus for removing trash constructed in accordance with the present invention.
  • FIG. 3 is a longitudinal sectional elevation illustrating a modified form of the invention.
  • the drawing illustrates a carding machine having a main cylinder and carding means along a substantial portion of the main cylinder provided with card clothing in carding relation to card clothing on said main cylinder.
  • Apparatus for removing trash from the carded fibers after being subjected to a carding action by the clothing of the main cylinder and the carding means prior to delivery of the carded fibers to a doffer includes a plate A having a portion conforming generally to the card clothing on the main cylinder.
  • Means B position the plate in superposed spaced relation to the card clothing on the main cylinder between the carding means and the doffer.
  • the plate defines a passageway C permitting removal of trash therethrough at least partially responsive to centrifugal force imparted to the trash by the main cylinder but retaining the fibers for delivery to the doffer. Thus, a substantial portion of the trash is removed while the cleansed fibers are retained for delivery by the main cylinder to the doffer.
  • the main cylinder 10 is illustrated as being carried between the usual arches 11.
  • the main cylinder 10 has card clothing 12 thereon with teeth 13 pointing in the direction of rotation of the main cylinder, as illustrated by the arrow in FIG. 1.
  • the fibers (not shown) being carded pass between the carding means broadly designated at 14 and the main cylinder from whence they are delivered to the doffer 15 which turns in the direction of the arrow illustrated in FIG. 1.
  • the doffer 15 is provided with a cover 16 and a triangular shaped bar 17 is placed between the front door plate and the doffer cover for the purpose of sealing this area of the card against removal of fibers and confining air currents adjacent the main cylinder.
  • the front top plate A conforms generally to the card clothing on the main cylinder and is illustrated as being spaced beneath the carding means in the form of stationary carding plates broadly designated at 14. It has been found that a spacing of approximately one-eighth inch will produce satisfactory results.
  • the plate A is beveled as at 18, and is preferably also tapered rearwardly as at 19 to join a thickened portion 20. It is thought to be significant that the plate is beveled adjacent a lower edge rearwardly to enlarge the effectiveness of the passageway adjacent thereto.
  • passageway be thus positioned adjacent the carding means, but it also appears that a passageway or a plurality of passageways may be advantageously positioned in the plate other than at a I marginal edge or otherwise along the main cylinder between the means feeding fibers to the main cylinder and the doffer.
  • the stationary plate 14 may include clamping means 23 for fastening the clothing,22 upon the plate portion 24 as set forth in the aforesaid patents.
  • the setting between the clothing of the stationary plate 14 and the clothing of the main cylinder is preferably about 0.050 inch, whereas, the portion of the plate A adjacent thereto is preferably set from about 0.017 to about 0.022 inch from the clothing of the main cylinder.
  • the opposite edge of, the plate 20 illustrated at 20a is set at about 0.050 inch.
  • Suitable means B positions the plate A in superposed spaced relation to the card clothing 12 on the main cylinder between the carding means 14 and the doffer 15.
  • Such means includes the bolts illustrated at B which pass through the plate A and into respective arches 11.
  • shims may be utilized to vary the settings or additional bolts threaded into the plate and bearing against the arches, and the like, may be employed to achieve the desired settings.
  • the plate in part defines a passageway C permitting removal of trash therethrough at least partially responsive to centrifugal force imparted to the trash by the main cylinder but retaining the fibers for delivery to the doffer. It has been found that a negative pressure is created producing suction at the passageway. In other words, long fibers outside the plate A, if placed close to the passageway C, will be drawn in and become subject to the action of the main cylinder. This action explains, at least in part, the fact that a large amount of particulate trash is removed through such passageway as illustrated in FIG. 2, while the long fibers are retained subject to the action of the main cylinder.
  • FIGS. 1 and 2 the front door plate is illustrated as assuming its customary configuration.
  • the front door plate is carried by a bracket or forearm 25 which has pivotal connection as at 26 with a bracket 27 fixed with respect to the arches 11. It has been found that undesirable short fibers and additional particulate trash may be removed by providing an additional passageway 28, as illustrated in FIG. 3, between the leading edge of the front door plate and the trailing edge 20a of the top front plate.
  • the passageway 28 is formed in part by a bevelled portion 29.
  • a rearward tapered portion 30 extends to the full plate thickness as illustrated at 31.
  • the trash thus removed may be collected by suitable suction nozzle (not shown).
  • suitable suction nozzle (not shown).
  • Special nozzles may be constructed for this purpose or existing removal devices may be adapted to serve the purpose.
  • a carding machine having a main cylinder, means feeding fibers to said main cylinder, and stationary plate means carried in superposed fixed spaced relation to the card clothing on the main cylinder having card clothing in carding relation to card clothing on the main cylinder, apparatus for removing trash from carded fibers prior to delivery of the carded fibers to a doffer comprising:
  • said stationary plate means having an edge opposite said sharpened lower edge
  • E. means positioning said sharpened lower edge below said opposite edge and in spaced relation thereto;
  • said sharpened lower edge and said opposite edge defining a passageway permitting removal of trash therethrough at least partially responsive to centrifugal force imparted to the trash by the main cylinder but retaining the fibers for delivery to the doffer;
