Definitions

  • ABSTRACT OF THE DISCLOSURE Apparatus for automatically tucking the loose end of a wound textile sliver ball into the ball.
  • a guide positions the loose end adjacent a blade, which blade is movable towards and into the wound ball along a path generally transverse to the axis about which the ball was wound and generally tangential to the outer circumference of the ball; the blade first engaging the loose end of the sliver and then penetrating the ball to tuck the loose end therein.
  • This invention relates to the formation of balls of textile sliver.
  • Such balls are wound by means of a driving roller which causes the ball to turn on a rotary spindle to which the sliver is fed with a traversing action to give a so-called cross-wound ball.
  • the ball is doffed, usually by being slid off the free end of the rotary spindle. In the past this was carried out manually but more recently automatic dofiing has been introduced so that the ball is pushed mechanically oif the spindle.”
  • the sliver end is automatically tucked into the ball by means of apparatus having a support for the ball, a tucking blade, and means for controlling the relative positions of the sliver end and the blade in an axial direction so that when the blade is caused to penetrate the surface of the ball it first engages the sliver end and then enters the ball in a generally tangential direction and generally transverse to the axis of the ball (that is the line through the ball about which the ball was wound) so as to tuck the sliver end into the ball.
  • apparatus having a support for the ball, a tucking blade, and means for controlling the relative positions of the sliver end and the blade in an axial direction so that when the blade is caused to penetrate the surface of the ball it first engages the sliver end and then enters the ball in a generally tangential direction and generally transverse to the axis of the ball (that is the line through the ball about which the ball was wound) so as to tuck the sliver
  • a line may intersect a circle either as a diameter, as a chord or as a tangent.
  • the outer circumference of the wound ball as a circle (taken in a plane generally transverse to the axis about which the ball was wound) and considering the path of the tucking blade as a line, it is readily apparent that the path of the blade cannot be a true tangent to the ball since penetration of the ball by the blade would then be completely eliminated. Further, it has been found that effective tucking is not obtained if the blade follows a diametrical path. Rather, the present invention contemplates that the blade path will follow a chord through the circle.
  • this path is referred to for convenience as generally tangential.
  • the path of the blade is not necessarily linear.
  • the path of the blade movement should be directly 3,385,533 Patented May 28, 1968 at right angles to the axis about which the ball was wound. It may, for example, be inclined at a small angle, for example, an angle equivalent to that at which the turns are wound on the ball by the traversing action of the nozzle.
  • the blade In order to provide the necessary register between the blade and the sliver end so that the latter is engaged and tucked into the ball the blade itself is preferably fixed in a direction parallel to the axis of the ball and the axial position of the sliver end is controlled. The alternative would be to move the blade axially to a position for engagement with the sliver end but this introduces undue complication to the operating mechanism.
  • This mechanism may conveniently be pneumatically operated. It is, however, also possible for the blade to be completely fixed and for the necessary penetration to be brought about by movement of the ball in relation to the fixed blade.
  • the blade may execute a second stroke so that the sliver end is held in position even more firmly.
  • the blade may be of approximately the same width as the sliver to be wound and may be secured to a mounting permitting a slight degree of swivelling movement. It is found that the best results are obtained if the blade has a square chisel-like edge but other configurations are also possible and the term blade is intended to cover any construction of elongated member which is capable of engaging the sliver end and tucking it into the ball.
  • a locating member may be provided which may include a guide portion and a stop. Accordingly when the ball is moved on to the support the sliver end is automatically guided into the position of register and this may be assisted by the provision of an air nozzle which serves to blow the sliver along the guide portion and into contact with the stop.
  • All of the operations just described may be carried out while the ball is still on the winding machine in which case the winding spindle constitutes the support for the ball.
  • the ball is first doffed before the tucking operation in which case the tucking apparatus constitutes a separate component.
  • the support for the sliver ball may then be in the form of a cradle and in order to hold the ball while the blade is driven the ball may be raised from the cradle to bring it into engagement with a stationary plate.
  • FIGURE 1 is a plan view showing the tucking apparatus in relation to the winding apparatus
  • FIGURE 2 is an elevation showing the tucking apparatus immediately before operation
  • FIGURE 3 is a perspective view corresponding to FIGURE 2;
  • FIGURE 4 is an elevation corresponding to FIGURE 2, showing the apparatus during operation, and,
  • FIGURE 5 is a perspective view corresponding to FIGURE 4.
  • FIGURE 1 shows the relationship between these two components.
  • the tucking apparatus may be used independently of the winding apparatus and it is shown effectively in isolation in the remaining figures.
  • FIGURE 1 the winding apparatus itself is shown in outline and its operation is described in more detail in the copending United States application No. 469,725, dated July 6, 1965, now Patent No. 3,348,783.
  • a sliver ball 1 is wound on a spindle 2, by means of a driving roller 3.
  • Sliver 4 is supplied to the ball 1 by a nozzle 5 which is caused to traverse as indicated by the arrow 6, to provide a cross-wound ball.
  • the traversing action of the nozzle 5 is first stopped so that the last turn or part turn of sliver is wound on the ball free of cross wind as shown at 7.
  • the nozzle 5 is stopped at a pre-determined position so that the sliver end is also in a pre-determined position in relation to the remainder of the ball 1 which facilitates the subsequent tucking operation.
  • the spindle 2 includes a non-reversible mechanism which prevents the sliver from unwinding from the ball 1 and this in combination with the trapping of the sliver by the bar 11 and assisted by the provision of a knife 15 which moves with the stripper plate 13, causes the sliver 4 to 'be parted as the ball is doffed so that the loose end hangs down in front of the ball.
  • the ball 1 is received by a cradle 20 forming part of the tucking apparatus and is located in the position shown as 1A in FIGURE 1. In this position the ball is located beneath a holding plate 21 which is omitted from FIGURE 1 for simplicity.
  • the subsequent operation of the apparatus is controlled pneumatically from the same pneumatic control circuit as controls the winding apparatus of which the tucking apparatus etfectively forms part. Successive stages in the operation are controlled by appropriate pneumatic valves. As the stripper plate 13 moves to push the ball off the spindle 2 its extension 14 strikes a toggle trip switch 8 which, how ever, when engaged in this direction does not operate.
  • a guide surface 22 the shape of which is best seen in FIGURE 1 prevents the sliver end from getting behind a tucking blade 25.
  • an air nozzle 23 blows the sliver end along the guide surface until the sliver end comes into engagement with a stop 24 in which position the sliver end is in register with the blade 25.
  • This blade is of approximately the same width as the sliver and is formed with a blunt chisel edge 26. It is attached to the end of a piston rod of a pneumatic ram 28 by means of a mounting 27 recessed to engage a guide bar 32 which is shaped so as to allow a slight degree of swivelling movement of the blade during operation. Operation of the ram 28 drives the blade 25 vertically and its location is such that its stroke of travel causes it to enter the ball 1 in a generally tangential direction.
  • a pair of lifter brackets 30 are raised by a pneumatic ram 31 so as to pass upwardly between the rails defining the cradle 20 and thus to lift the ball 1 into engagement with the holding plate 21. This prevents rotation of the ball 1 when it is penetrated by the blade 25.
  • FIGURES 4 and 5 show the raised position of the lifter brackets with the blade 25 at the full extent of its operative stroke in which it is inserted into the ball 1. As can be seen it enters the ball in a generally tangential direction.
  • the tucking apparatus works in conjunction with the winding apparatus and shares its pneumatic circuits. As mentioned previously, however, the tucking apparatus may be completely independent. Moreover, although the blade 25 is shown operating with a ball supported on the cradle 20 a similar operation could occur with the ball 1 merely supported by the spindle 2. As already described this spindle has a non-reversing mechanism so that the ball would be prevented from rotating. With such an arrangement the ball would then be doifed after the completion of the tucking operation. In another example the ball could be lowered on to a stationary blade in order to impale it on the latter so as to tuck-in the end, and then raised to clear the blade.
  • Apparatus for securing the end of a sliver extending from a cross-wound ball of the type wound about an axis and having a generally circular outer circumference taken in a plane generally transverse to said axis comprising: support means for supporting the ball, a tucking blade positioned proximate to said support means for operative cooperation therewith, actuating means for causing relative movement between the blade and the support means so that the blade moves, relative to the ball, when a ball is mounted on the support means, in a direction generally tangential to the outer circumference and generally transverse to the axis of the ball, and control means for controlling the relative position of said blade and said sliver end so that upon operation of said actuating means with a ball on the support means the blade will first engage the sliver end and then penetrate the ball in said generally tangential and generally transverse direction and thereby tuck the sliver end into the ball.
  • Apparatus according to claim 3 in which said actuating means comprises a pneumatically operated drive mechanism.
  • Apparatus for securing the end of sliver extending from a cross-wound ball of the type wound about an axis and having an outer circumference taken in a plane generally transverse to said axis by tucking the end into the ball the apparatus having a support means for supporting the ball, a tucking blade, means for driving said blade in a direction generally tangential to the outer circumference of a ball on said support and a location means -for locating the end of the sliver extending from said ball in a position for engagement with said blade, whereby movement of said blade tucks said sliver end into said ball.
  • said locating means includes a guide portion and a stop.
  • Apparatus according to claim 8 and including an air nozzle for blowing the end of sliver along said guide portion and into contact with said stop.
  • said sup port means includes a cradle mounted to hold said sliver ball.
  • the support means further includes a lifting means for raising said ball from said cradle to bring it into engagement with a stationary plate so as to hold the ball stationary while the blade is driven.
