Definitions

  • the present invention relates to a new and improved apparatus for separating opened fiber flocks from a fiber flock carrying transporting air stream at a stationary feed chute connected with a pneumatic flock transporting duct, the stationary feed chute being provided with a perforated wall and forming a fiber flock layer which is to be supplied to a spinning preparatory machine.
  • a primary object of this invention is to provide just such type apparatus which effectively and reliably fulfills the existing need in the art and overcomes the aforementioned drawbacks.
  • Another and more specific object of the present invention relates to an improved apparatus for separating fiber flocks from a transporting air stream so as to produce a sufficiently uniformly condensed fiber flock connected with a penumatic flock transporting duct is generally manifested by the features that the upper part of the feed chute is equipped with at least two inlet openings for the fiberflock carrying transporting air stream and a centrifugal wheel is concentrically arranged at each such inlet opening.
  • FIG. 1 is a fragmentary cross-sectional view of a first embodiment of inventive apparatus, taken substantially along the line B-B of Flg. 2;
  • FIG. 2 is a horizontal cross-sectional view of the apparatus depicted in FIG. 1, taken substantially along the line AA thereof;
  • Flg; 3 is a fragmentary cross-sectional view of inventive apparatus similar to the showing of FIG. 1, but illustrating a modified construction thereof;
  • FIG. 4 is a further embodiment of the inventive apparatus for separating fiber flocks from a transporting air stream as contemplated by this invention.
  • a respective inlet opening 4 and 5 At a large side wall of this detachable upper chute portion or part 2 of the fiber flock feed chute l and to each of the vertical chute axis 3 there is arranged a respective inlet opening 4 and 5, in other words a total of at least two inlet openings 4 and 5 are provided for the transporting air stream laden with the opened fiber flocks.
  • centrifugal wheel 6 and 7 disposed concentrically with respect to their associated inlet openings 4 and 5.
  • These centrifugal wheels 6 and 7 can be constructed, for instance, as round discs provided with smooth surfaces or with radial ribs or, as experiments have proven, can suitably consist of centrifugal fan wheels.
  • centrifugal wheels 6 and 7 are driven so as to rotate in opposite rotational directions. Furthermore, these centrifugal wheels 6 and 7 are preferably driven in such a manner that the directions of rotation of the wheels 6 and 7 between their axes of rotation are directed downwards.
  • each of the two centrifugal or fan wheels 6 and 7 with a respective curved deflecting or diverting wall member 8 and 9.
  • These curved'deflecting walls 8 and 9 extend approximately at least over the upper half of the associated wheel 6 and 7 and possess an approximately semi-circular configuration or preferably a spirally-shaped configuration.
  • both deflecting walls 8 and 9 are arranged in such a fashion that their radialspacing from the periphery of the associated wheels 6 and 7 and from their axes of rotation increases in the directions of rotation of these wheels 6 and 7 as indicated by the arrows of FIG. 1.
  • an appropriately displaceable or moveable flow guide member for the purpose of evening-out possible irregularities of the flock distribution which may arise.
  • This guide member can be constructed, for intance, in the form of a sliding plate or baffle 10 or, as shown for the modified embodiment of FIG. 3, can be constituted as a pivotal guide blade 11 which can be rocked or pivoted-in a direction transverse to the air flow indicated in such drawing by the arrows.
  • the rdial distance of the curved deflecting walls 8 and 9 from the periphery of such wheels and from the axes of rotation of wheels 6 and 7 here likewise increases in the direction of rotation, so that in this case the outflow or exit ends of the deflecting walls 8 and 9 extend towards the side walls of the feed chute 12 and a respective guide blade 11 is suitably mounted at both sides within the chute 1, as shown.
  • the drive for the centrifugal wheels 6 and 7 is achieved, but such can be driven for instance through the agency of a suitable electric motor 13 and belts, or in fact in any otherappropriate manner.
  • the control and actuation of the guide elements and 11 as well as the drive 13 does not constitute part of the subject matter of this inven-- tion, yet it is to be mentioned that such can be controlled and actuated, for instance manually, mechanically or automatically, by means of any suitable adjusting mechanism.
  • One such possible type of adjusting mechanism 15 has been shown as a pinion and rack drive which, in the arrangement of FIG. 1, can be used for selectively positioning the guide baffle or slide 10.
  • centrifical wheels 6 and 7 which do not have any fan action, since a fan or ventilator in the flock transporting duct can be sufficient for conveying the fiber flocks.
  • adapting or adjustment means at the region of the fork-shaped connection duct 12 for the purpose of altering the distribution of the transport air stream at both of the legs 12a of such fork-shaped duct 12.
  • an adjustable air flow separating wall 15' formed of a material of limited flexibility, adjustment of such separating wall being possible at substantially right angles to the axes of the inlet openings 4 and 5 respectively.
  • This separating wall 15' is movable in a plane defined by such two axes of the inlet openings 4 and 5 through the action of an eccentrically mounted eccentric cam 14 or similar device.
  • the air flow separating wall 15 can be correspondingly displaced between its depicted full and phantom line positions so as to adjust or regulate the effective flow cross-sectional areas of the two legs 12a of the connection duct 12 as should be readily apparent.
  • an appuratus for separating opened fiber flocks from a transporting air stream carrying the fiber flocks at a feed chute connected with a pneumatic flock transporting duct, the improvement comprising an upper chute portion, said upper chute portion being provided with at least two inlet openings for the flock carrying transporting air, and a respective centrifugal wheel provided for each inlet opening rotatably mounted on a substantially horizontal axis and substantially concentrically arranged with respect to its associated inlet opening, means for driving said centrifugal wheels of each two neighboring inlet openings so as to rotate in opposite directions.
  • each such deflecting wall member extending over at least the upper half of its associated centrifugal wheel, each said deflecting wall member being arranged such that its radial spacing from the periphery of its associated centrifugal wheel increases in the direction of rotation of such centrifical wheel.
  • each said deflecting wall member possesses a substantially spirally-shaped configuration.
  • said deflecting wall members define at least one exit location for the transporting air stream, and an adjustable guide member for the transporting air stream provided at said exit location.
