Definitions

  • This invention relates to a sealing arrangement for a spinning apparatus, and more particularly to such an arrangement for preventing, or at least inhibiting, passage of air to the interior of a rotary spinning chamber through passages other than the separated fiber feeding opening or the yarn withdrawing channel.
  • the fibers are fed after separation to the socalled collecting surface in the spinning chamber by the vacuum developed in the chamber by the usual air escape openings, the openings expelling air from inside the spinning chamber by centrifugal force.
  • Such expelled air usually enters a confined space surrounding the spinning chamber, whence it passes through a suitable opening to the ambient air.
  • Another object is to prevent the clogging of a labyrinth seal by loose fibers during cleaning of the apparatus.
  • a sealing arrangement in which two coaxial annular projections, an outer and an inner projection, extend substantially axially beyond a continuous annular side wall of the spinning chamber.
  • the outer projection engages a circular groove of the cover of a casing in which the spinning chamber is mounted to form therewith a labyrinth seal States Patent ice which substantially prevents passage of air into the spinning chamber from the space between the casing and the spinning chamber.
  • the inner projection passes with small clearance through a central opening in the top wall of the casing either projecting beyond the outer surface of this wall or terminating at its outer surface.
  • FIG. 1 is an elevation, partly in axial mid-section, of a spinning apparatus embodying the present invention.
  • FIG. 2 is a detailed view of the sealing arrangement of the present invention, being a fragmental portion on an enlarged scale of the embodiment shown in FIG. 1.
  • the spinning chamber 1 which is shown in FIG. 1 is substantially pot-shaped having a bottom which is integral with a shaft 2, having an axial passage 3 extending from the spinning chamber therethrough to constitute the yarn withdrawal passage of the apparatus.
  • Shaft 2 is mounted in bearings 4 in the machine frame 5, which is only fragmentally shown, and is provided adjacent its ends with a pulley 6 by means of which a belt (not shown) rotates the spinning chamber.
  • the spinning chamber 1 is mounted within a casing 101 into which the spinning chamber expels air through the usual escape openings 7 therein, this expelled air being received in a surrounding space 16 between the spinning chamber and the casing.
  • An opening 30 in a wall of the casing connects the space 16 with the ambient atmosphere.
  • the casing 101 is provided with a top wall 14, which in the present example has a central opening 141 therein.
  • the top wall 14 also has on its inner surface an annular groove 13 which is coaxially disposed with respect to the axis of rotation of the spinning chamber.
  • the spinning chamber 1 has a continuous annular side wall 91 extending substantially axially from the bottom of the chamber to an open end thereof.
  • Inner walls divide the continuous annular side wall of the spinning chamber into two parts, each part being conical and being narrowed from the maximum inner diameter of the spinning chamber to provide the usual collecting face of the chamber.
  • An annular projection 12 extends from the annular side wall Q1 of the spinning chamber 1 into the annular groove 13 of the top wall 14, being spaced from the surface of the groove. Thus a labyrinth seal is provided between the surface of the groove 13 and the top wall 14.
  • the central opening 141 in cover 14 serves for cleaning the spinning chamber.
  • the central opening 141 is coaxial with the axis of rotation of the spinning chamber 1 and a second annular projection extends from the side wall of the spinning chamber into this central opening adjacent the rim of the opening .141, extending at least as far as the top surface of the top wall 14.
  • the second annular projection 9 extending above the labyrinth formed between the first annular projection and the top wall 14 of the casing 101, protects the labyrinth against deposits of separated fibers therein and maintains it in open condition, preventing the labyrinth from interfering with rotation of the spinning chamber 1.
  • a movable cover 20 is provided for closing the opening 141 in the top wall 14 of the casing 101 and for closing the open side of the spinning chamber 1.
  • the movable cover is formed as a tiltable cover which may be tilted by means of a handle 21 about a pivot 22.
  • the movable cover has a circular boss 12% thereon having a diameter slightly less than the diameter of the second annular projection 19, for closing the spinning chamber 1. The boss may therefore enter the space surrounded by the second annular projection 9 when the movable cover closes the opening in the top Wall of the casing 1.
  • the movable cover 20 has an annular recess 121 in its inner face surrounding the annular or circular boss 120. It is thus possible for the coaxial annular inner projection 9 to extend above the outer surface of the to; Wall 14 of the casing 101 in order to project still further above the labyrinth and give it greater protection during cleaning of the spinning chamber;
  • the movable cover 20 is formed with a feeding opening 23 extending therethrough and through the circular boss 120 in order to feed separated fibers 24 into the spinning chamber 1. Furthermore a fiber separating mechanism 25 of known construction may be fixed to the outer surface of the movable cover 20, and such a mechanism is illustrated in FIG. 1.
  • rotary motion is given the spinning chamber 1 by rotation of the pulley 6.
  • Rotary motion of the spinning chamber creates a vacuum in the space 15 within the spinning chamber by centrifugal discharge of air through the escape openings 7.
  • This vacuum draws separated fibers 24 into the spinning chamber from the separating mechanism 25, and these separated fibers are transformed into yarn in known manner.
  • the yarn 26 is withdrawnthrough the withdrawal channel 3 by the action of rollers 27 therebeyond and is distributed by a guiding roler 28 about a bobbin 29 upon which the yarn is wound.
  • Through the influence of the vacuum in the spinning chamber air flow from the ambient atmosphere into the chamber takes place through the feeding opening 23 and through the withdrawal channel 3.
  • the resistance to the passage of air created by the outer coaxial annular projection 12 within the circular groove 13 prevents or limits air from flowing from the space 16 between the spinning chamber and the casing 101 into the space 15 within the spinning chamber 1. In consequence thereof the air entering the spinning chamber enters through the feeding opening 23 and through the withdrawal channel 3 almost exclusively, and correct operation of the spinning chamber results.
  • the spinning chamber 1 is filled with separated fibers 24 and requires cleaning, then the spinning chamber is cleaned by tilting the tiltable cover 20 and removing the undesired fibers.
  • the effect of the elevation of the inner projection 9 above the outer projection 12 is to prevent possible penetration of fibers into the labyrinth. This is an important advantage of the present novel sealing arrangement.
  • a sealing arrangement for a spinning machine com prising a casing, a spinning chamber mounted in said casing for rotation about an axis of rotation, said casing having a top wall with an annular groove on its inner face coaxially disposed with respect to the axis of rotation of said chamber said chamber having a continuous annular side wall extending substantially axially from the bottom of said chamber to an open end thereof, and an annular projection extending from said side wall of said chamber into the annular groove on said top wall spaced from the surface of the same to form a labyrinth seal therewith.
  • top wall has a central opening therein substantially coaxial with the axis of rotation of said chamber, and including a second annular projection extending from said side wall at the open end of said chamber into the central opening in said top wall adjacent the rim of said opening and at least as far as the top surface of said top wall to prevent fibers from entering the labyrinth seal between said first-named projection and the groove in said top wall during cleaning of said chamber.
  • a sealing arrangement as defined in claim 6 including a circular boss on said movable cover having a diameter slightly less than the diameter of said second annular projection, whereby said boss may enter the space surrounded by said second anular projection when said movable cover closes the opening in the top wall of said casing.
  • a sealing arrangement as defined in claim 9 including a fiber separating mechanism mounted on said movable cover and connected to the feeding opening therein for supplying separated fibers to said spinning chamber.
