Definitions

  • a bobbin holder for fastening yarn bobbins to a bobbin This invention relates to a bobbin holder of an essentially cylindrical shape, formed of two hollow shaft halves within which the rolling bearing, the spring brake and two locking elements are accommodated, the upper and lower ends of said locking elements projecting from longitudinal slots formed along the cylindrical body of the bobbin holder.
  • the lower ends of the two locking elements are for carrying the bobbin body, whereas the upper ends are for engagement by a centering ring sliding along the cylindrical body of the bobbin holder and for being carried to a position wherein said locking elements are ready for duty and from which they tend to pass to an operative position owing to the weight thereof.
  • bobbin holders have locking elements formed of two identical plates located against one another and pivoted to one another which, on falling, grip the bobbins within the inner shoulder thereof.
  • bobbin holders are provided with plates with simple clamping foot.
  • bobbin holders of a different length are to be used depending upon whether the bobbins have a short or a long inner neck; otherwise, should only bobbin holders for long neck bobbins be used, short neck bobbins would hang down into the bobbin creel to a too great extent.
  • the object of the present invention is to provide a bobbin holder avoiding the above described drawbacks and capable at the same time of being manufactured in large amounts from low cost material and thus with a great economical advantage.
  • the smaller plate operates to promote the balancing movements and to stabilize the various positions.
  • Another object of the present invention is to provide for the adjustment of the inner brake by means of an adjustable screw without any need for taking away the bobbin holder.
  • a third object is to provide plates, in which the feet or lower ends are in the form of steps.
  • said bobbin holder can grip the long or short inner neck bobbins, without short neck bobbins hanging down for this into the bobbin creel to a too great extent and causing a loss of positions.
  • FIGURE 1 is a side view of the bobbin holder
  • FIGURE 2 is a sectional view according to line H-II in FIGURE 1 of the bobbin holder showing the bobbin at clamped position; wherein the clamping element in dotted lines has been added for greater clarity;
  • FIGURE 3 is a fragmentary sectional view of the bobbin holder, wherein the clamping elements are shown at retracted position and the clamping element in dotted lines has been added for greater clarity;
  • FIGURE 4 is a sectional view according to line IV--IV of FIGURE 1;
  • FIGURE 5 is a sectional view according to line V-V of FIGURE 1.
  • Shaft 1 is so suspended as to be pivoted around a screw 3 the end of which penetrates chamber 2 from the top and being surrounded within said chamber by braking members and by the other end. connected to the bobbin creel of the machine.
  • Shaft 1 is formed of two separate halves, which are held together by annular springs 21 and 22.
  • the two plates 5 and 6 (at clamped bobbin position in FIG. 2), pivoted to each other at 10, can upwardly or downwardly slide, drawn by ring 20 engaging the projecting portion 7 of the upper end of plate 6 with rib 24.
  • the movement of plates 5 and 6 is guided by feet 11 and projecting portion 7, slidable within the respective slots 4", 4" and 4'.
  • Slots 4' and 4" are on the same plane (FIGS. 4 and 5), whereas slot 4" is arranged on a plane parallel to the plane of the other slots (FIGURE 5).
  • portion 8 of plate 6 will pivot on rib 24, the plates will be removed from the internal position thereof and sidewise outwardly inclined due to weight thereof.
  • the plates On downward guided movement, the plates; will as far as possible move their feet away, which feet are guided by pins 9 and 9', respectively, pin 9 (not shown in the figure) being located on the other half of shaft 1.
  • the two plates a are-interconnected at 10, so thatone plate will draw the other. Since one plate is shorter than the other and the shortest plate is drawn by the longest one, only the upper end of the longest plate will project from slots 4 or 4' to provide the attachment points for the drawing movement by ring 20. As a result, the Width of the slots is reduced to a half, as each slot is contemplated for the width of only one clamping plate.
  • the feet 11 of plates 5 and 6 are in the form of steps and grip the short neck bobbins at the upper-most location indicated at 25 and the long neck bobbins at the lowermost location indicated at 26, this in order to gain space in the bobbin creel.
  • the bearing and brake system is arranged within chamber 2 and comprises ball bearing 23, brake disc 12, support spring 13 and brake spring 14.
  • the assembly is secured to the bobbin creel 15 by a hollow screw 3 engaging the support spring 13 by the head thereof.
  • brake spring 14 engages the head of screw 16 and with the upper portion thereof the brake disc 12.
  • -Screw 16 is caused to advance or to retract by turning the same through nut 17; thus, brake spring 14 can be more or less compressed.
  • Support spring 13 will be more or less compressed depending on weight of bobbin: as a result, spacing between brake disc 12 and screw head 16 will vary and compression of brake spring 14 will vary accordingly. Compression of brake spring 14 can be brought back to an exact value by adjusting screw 16.
  • a bobbin holder for fastening yarn bobbins to a bobbin creel comprising two movable plates for bobbin clamping, exiting from side slots in the bobbin holder, a centering ring and an adjustable braking device, characterized in that the movable plates are of a different length and pivoted to each other at the upper end thereof; the upper end of said longer plate being provided with two opposite projecting parts or elements, adapted to be alternatively engaged by an inner rib of the centering ring during the fastening operation of the bobbin, said braking device being directly adjustable from outside.
  • a bobbin holder according to claim 1 characterized in that the feet of the movable clamping plates are in the form of steps, and a respective pin located at the bottom of the bobbin holder for guiding said feet during movement.
  • a bobbin holder according to claim 1, characterized in that said braking device is adjustable from outside and comprises a first hollow screw secured to the bobbin creel, a second coaxial screw movable within the former, which screws exit at the top of the bobbin holder, a braking spring bearing with its lower end on the head of said second screw and with the upper end on a braking disc; said second screw having graduation marks at the outer end thereof for adjusting the tension of the braking spring.
  • a bobbin holder according to claim 3 characterized in that in order to adjust the braking effect said second screw has a threaded section at the lower end thereof, screwing on a corresponding threaded section at the lower inner portion of said first hollow screw, so that on turning said second screw the compression of the braking spring can be varied.
