Definitions

  • the present invention relates generally to drawing frames and to a novel method of and means for feeding, depositing and laying out bundles of filaments or Webs into an open container or sliver can and, more particularly, to a novel arrangement and construction of a guide tube carried on a rotatable coiler head permitting safe and high speed delivery of the web or sliver into the sliver can.
  • the webs or slivers are generally fed into a rotatable coiler head assembly provided with a guide tube having a passageway through which the slivers are directed for depositing into a sliver can the slivers in superimposed but circumferentially displaced or angularly offset, continuous looped coils or helixes.
  • the sliver can or container may preferably be mounted for rotation and eccentrically arranged with respect to the axis of rotation of the coiler head assembly.
  • drawing frames of apparatus for the continuous pneumatic removal of dust or fluff loosened from the strands of fibers has created the attendant requirement that the drawing frames be reliably and economically operated at delivery speeds of the slivers or webs which are substantially greater in magnitude than the delivery speeds heretofore utilized.
  • the employment of drawing frames operated at these greater delivery speeds necessitates that a considerably greater length of the webs or slivers is deposited or laid out in the sliver container per unit time than hitherto required and, in turn, requires an increase in the tangential speed or velocity, particularly of the coiler head.
  • the teachings of the present invention provide a novel method and means for depositing and laying out the webs or slivers while simultaneously obviating the afore-mentioned disadvantages and permitting high speed delivery and running of the coiler head assembly.
  • a rotatable coiler turntable or plate which carries a novel type of guide tube constructed and oriented on the coiler turntable so as to permit a high rate of revolution of said turntable, and yet, safely handles the slivers.
  • the guide tube is bent or curved to assume such a configuration that the slivers are directed in a predetermined path of travel and emerge from the delivery end of the guide tube in a direction extending downward and rearwardly with respect to the direction of rotation of the coiler turntable.
  • the relative velocity of the web has a resolved tangential or horizontal velocity component which is substantially equal and opposed to the tangential velocity of the coiler turntable; more specifically, it is equal to the tangential velocity at the outlet region of the coiler head assembly.
  • the novel guide tube is oriented on the coiler turntable in such a manner as to deflect the web or slivers between a substantially coaxial inlet portion and a radially displaced delivery portion.
  • the delivery portion of the guide tube extends toward the circumference of the turntable and in close proximity thereto, the point of dis charge of the outlet of said guide tube lying in a tangential plane with respect to a radius of the turntable taken through said point of discharge.
  • the absolute velocity component of the emerging web is directed normal to the plane of the turntable so that no undesirable forces will be applied to the delivered Web. In this manner it is now possible to safely and reliably handle slivers delivered and layed out at high speeds without fear of damage and fraying thereof, while permitting increased rotational speeds of the coiler head assembly.
  • Yet a further object of the present invention is the provision of novel means and a method of directing slivers in a controlled manner through a coiler head assembly wherein the direction of discharge of the slivers is rearwardly and downwardly directed with respect to the direction of rotation of a coiler turntable.
  • Still a further object of the present invention is to provide a novel arrangement and construction of a coiler guide tube for delivering slivers and the like in a predetermined direction and with a horizontal relative velocity component which offsets and is equal to the tangential ve locity of at least the point of discharge or discharge opening of the guide tube and its carrying turntable.

  • FIGURE 5 is a sectional view of the coiler head assembly shown in FIGURE 4, but taken along lines V-V thereof, and illustrates a velocity triangle for the delivered web;
  • FIGURE 6 is a top View of the coiler head assembly shown in FIGURES 4 and 5;
  • FIGURES 7 and 8 are diagrammatic views illustrating the forces and velocity conditions on delivery of the web from the coiler head assembly, in plan view and elevational view, respectively.
  • FIGURE 9 is an enlarged plan view of the delivery portion of the guide tube pursuant to FIGURES 4 through 6;
  • FIGURES 10 and 11 illustrate further forms of guide tube which may be employed in the coiler head assembly.
  • FIGURES 1 t0 3 a conventional coiler head assembly A heretofore known in the art is shown, said coiler assembly being provided with a rotatable coiler turntable 1 carrying thereon a guide tube 2 adapted to receive and guide the passing webs or slivers received from a suitable supply source.
  • the guide tube 2 is arranged on the turntable 1, rotating in the direction of the arrow 3, so as to be inclined downwardly and outwardly toward the periphery of the coiler turntable 1.
  • the guide tube 2 is disposed in an axial plane 11, taken normal to the plane of the paper of FIGURE 3 and extending through the center or axis of rotation 0.
  • the other parts of the conventional coiler head assembly A and the sliver can into which the guide tube opens and into which the webs are coiled have not been shown.
  • the web or slivers (not shown) are delivered from the outlet portion 2a of the guide tube 2 with a relative velocity V, which may be resolved into the radial or horizontal component V and the normal or vertically directed relative velocity component V
  • the tangential velocity U of the rotatable coiler turntable 1 in the region of discharge 10 of the outlet portion 2a, becomes operative of the relative velocity components V and V to produce the resultant components W and W respectively, as clearly indicated by the velocity triangles of FIGURES 2 and 3.
  • the web is therefore delivered with an absolute velocity W, which is the resultant of the velocity vectors W and W and merely schematically illustrated by the dashed-line of FIGURE 3.
  • the absolute velocity vector W extends downwardly out of the plane of the paper of FIGURE 3 in the direction of rotation of the turntable 1.
  • the novel method and coiler head assembly of the present invention overcomes these undesirable effects by reducing or eliminating the action of the centrifugal force due to the controlled rotation of the coiler turntable by providing a guide tube construction and assembly wherein the tangential velocity of the coiler turntable and a resolved component of the delivery velocity of the web at least partially compensate or offset one another.
  • a guide tube 4 which is preferably bent in three directions, having the inlet portion 5 coaxially arranged with the axis of rotation 0 of the turntable and a radially displaced and axially offset delivery or outlet portion 6.
  • the delivery portion 6 is downwardly inclined and rearwardly directed with respect to the rotational sense 3 of the coiler turntable 1.
  • the guide tube is further constituted by a substantially straight central portion 7 and a curved deflecting portion 8 disposed forwardly of said central portion 7 (see FIGURE 9).
  • the guide tube 4 is bent at an angle ,6 in the horizontal projection, which angle is about 45 degrees in the disclosed embodiment. This angle should preferably not be smaller than 30 degrees so that the web or sliver will not be deflected too abruptly.
  • the web Upon delivery from the delivery portion of the guide tube 4, the web emerges from the point of delivery 10 with a relative velocity V which, however, is directed downwardly and rearwardly with respect to the rotation of the coiler turntable 1 in the direction of the arrow 3.
  • the relative velocity V of the web lies in a tangential plane and forms substantially a right angle with a radius taken through the central point of discharge 10 of the outlet of the guide tube 4.
  • the relative velocity V of the web is resolved into the tangential component V and the verticallyextending relative velocity component V (see FIG- URE 5).
  • the tangential velocity U of the rotatable coiler turntable 1 in the region of web discharge is made equal in magnitude but in reversed direction to the tangential relative velocity component V so as to offset and cancel one another, whereby the absolute velocity W of the web is composed of only the vertical and downwardly directed resultant W, which in effect, is the same as the relative velocity vector V
  • the absolute velocity component W of the web causes the latter to emerge neatly and to be laid in the desired helical and centrally offset coiled configuration.
  • the rear wall or leading edge 6a of the guide tube 4 in the region of the outlet during rotation of the guide tube defines an imaginary circle of revolution having a radius r and indicated by the dotted line 11.
  • the center discharge point 10 in the outlet region of the guide tube 4 also forms an imaginary circle of revolution as indicated by the dotted line 12.
  • the discharge portion 6 of the guide tube is given such a curvature that it gradually and tangentially approaches the circle of revolution 11 from the outside.
  • the leading guide wall of the guide tube includes an inner wall which at least in the region of the discharge portion faces towards the axis of rotation of, the coiler turntable.
  • the speed of the turntable 1 may be controlled in any conventional manner, as for example, by employing a variable speed motor or other suitable drive means.
  • the delivery portion 6 of the guide tube shown in F1- URE 6 is designed to take into account the condition of discharging the web or slivers in a tangential plane and in a rearward and downward direction, but further, the curvature of the guide tube and especially the delivery portion 6 is constructed so as to ensure an absolute balance of the forces acting on the web upon delivery from the coiler head assembly.
  • the radial velocity as well as its radial acceleration on delivery must be made equal to zero.
  • the web in the delivery area of the guide tube 4 is subjected, on the one hand, to the centrifugal forces Z and Z and, on the other hand, to the oppositely directed Coriolis force C.
  • the reference numeral Z denotes the centrifugal force caused by the rotational movement of the outlet end of the leading wall 6a of the delivery region of guide tube 4 defining the circle of revolution 11 having a radius r, whereas Z is the centrifugal force resulting from the movement of the web along a path of travel having the radius of curvature R.
  • the magnitude of the relative velocity V of the web should preferably be made equal to the magnitude of the tangential velocity U at the coiler delivery point, see FIGURE 8.
  • the radius of curvature R of the guide tube 4 in the area or region of the delivery portion 6 of said guide tube can be calculated from the aforementioned equation, giving a solution of:
  • the angle a assuming a value up to 30 degrees. Consequently, the radius of curvature R of the guide tube can be calculated including the corresponding delivery portion 6 thereof and will therefore exceed r.
  • the delivery portion 6 or at least the end of the leading wall 6a must open or terminate at a point having the radius r, so that rotation of the end of the leading wall 6a defines said imaginary circle of revolution 11 of radius r, then it is found that the rear or leading wall 6a of the delivery portion 6 of the guide tube 4 tangentially approaches the circle of revolution 11 from the outside.
  • the deviation of the delivery portion 6 and the deflecting portion 8 of the guide tube 4 from the generatrix of the circle of revolution 11 is never really large since, preferably, at least these respective portions 6 and 8 of the guide tube are disposed in a plane which is inclined with respect to a horizontal at the angle a.
  • FIGURE 9 there is shown an enlarged plan view of the coiler head assembly pursuant to the present invention.
  • the radius R determining the curvature of the guide surface or leading wall 6a of the delivery portion 6 of guide tube 4 is exaggerated with respect to the radius r.
  • the delivery portion 6 of the guide tube 4 and provided with the guide surface 6:: extends through an angle 7 which, in actual practice, may amount to about 15 degrees.
  • the angle 0 through which the web is deflected from a radial to a tangential direction by the deflecting portion 8 of the guide tube may, by way of ex ample, be about degrees.
  • the deflecting portion 8 interconnects the substantially straight portion 7 disposed forward of the moderately curved inlet portion 5 with the delivery portion 6 of the guide tube 4.
  • the central por tion 7 of the guide tube 4 may also be arched or bent slightly rearward in the direction of rotation.
  • the curvature of the guide tube 4 should be as steady as possible.
  • the deflection from the central portion 7 to the delivery portion 6 and that from the inlet portion 5 to said central portion should have the largest permissible radius.
  • the central portion 7 should have a substantially radially extending length which is directed both outwards and downwards for directing the passage of the web in its travel from inlet portion 5 to delivery portion 6.
  • the closed guide tube 4 preferably having a circular or elliptical cross-section, may bereplaced by a guide tube 4a (FIGURE 10) having at least a bent open guide channel 6a having a U-shaped cross section.
  • horn-shaped guide tubes have proved to be quite satisfactory, i.e. guide tubes which are not only curved but also tapered in the direction from the inlet portion 5 to the delivery portion 6 (FIGURE 11).
  • the guide tube may also be curved in a single plane which connects corresponding points of the coiler assembly in the axis of rotation and at the circumference of the turntable, or alternatively, it may be curved in at least two planes as already shown.
