Definitions

  • ABSTRACT Coil winding machine for preferably conical cross-wound bobbins includes thread storage means for compensating for varying thread winding speeds, and means for automatically adjusting the length of the stored thread in accordance with the fullness with which the bobbin is wound.
  • My invention relates to coil winding machine for winding preferably conical cross-wound bobbins and more particularly to such coil winding machine having thread storage means for compensating for various thread winding speeds.
  • a further nonuniforrnity in the threads unwinding speed occurs during the winding of the cross-wound bobbin because the ratio of the larger and smaller diameters of the coil or bobbin on to the other continuously varies with the fullness with which the coil is wound.
  • a nonuniform thread unwinding speed has an especially highly disturbing effect when a thread from spinning or twisting frames is to be fed at absolutely constant speed to the conical cross-wound bobbins or cheeses, because varying speeds disadvantageously effect the quality of the thread in that, for example, the twist or thickness of the thread no longer remains uniform.
  • Winding machines with constant thread feed have been known heretofore to be provided with thread storing means. They are of rather complex construction, however, and therefore susceptible to trouble. Moreover, they are adjusted to control the members driving the cross-wound bobbins, which calls for intervention thereof in the path of the driving force and thereby necessarily causing complications. Furthermore, the control pulses only have a delaying effect on the winding speed so that the control circuit operates relatively sluggishly and tends toward over control.
  • coil winding machine for winding preferably conical cross-wound bobbins comprising thread storage means for compensating for varying thread winding speeds, and means for automatically adjusting the length of the stored thread in accordance with the fullness with which the bobbin is wound.
  • the thread storage means comprises a device for forming thread loops having at least one member connected to a carrying member for the cross-wound bobbin.
  • thread storage means comprising a device for forming thread loops that is connected is such a manner to the thread guide and to a carrying member for the cross-wound bobbin so that in a predetermined thread guide position, the length of the thread loop is the same independently of the fullness with which the bobbin is wound.
  • I provide a lever system connecting the loop-forming device to the thread guide, the lever system having an effective length of lever arm that is variable in dependence upon the position of a support member for the cross-wound bobbin.
  • FIG. 1 is a front elevational view of a winding station forming part of a winding machine wherein a frustoconical bobbin is shown at a stage shortly after the start of the winding operation;
  • FIG. 2 is a side elevational view of FIG. 11;
  • FIG. 3 is another view of FIG. 1 wherein the bobbin is shown at a stage wherein it is nearly fully wound.
  • FIGS. 1 and 2 there is shown a winding station of a coil winding machine having a frame support made up of lateral partitions 1 and 2, and intermediate wall 3 extending therebetween, and a crosspiece 4 extending substantially parallel to the intermediate wall 3 and secured thereto by a projection extending therefrom (note especially FIG. 2).
  • a helically grooved drive or cam roller 5 is mounted on a shaft 6 that is joumaled on the lateral partitions 1 and 2
  • a winding shaft 11 is mounted on a rotary spindle l2 similarly journaled on the lateral partitions 1 and 2.
  • Both the drive roller 5 and the winding shaft 11 are rotatably driven by conventional means which have been omitted from the figures in the interest of clarity and because they of themselves are not essential to the invention of this application.
  • a thread guide 7 is displaceably guided on a slide bar 8 secured at its ends to the lateral partitions l and 2.
  • a pin 9 (FIG. 2) extends from the thread guide 7 into the helical endless groove formed in the drive roller 5 and, as the latter is rotated, reciprocates the thread guide 7 along the slide bar 8.
  • a substantially U-shaped coil carrying member 14 has an angular extension 15 and is pivotally mounted thereby on a shaft 16 secured at the ends thereof to the lateral partitions 1 and 2, respectively.
  • a cross-wound bobbin or cheese 13 is rotatably carried by the carrying member 14 between the free ends of the legs of the U-shaped member 14.
  • a lifting rod 18 is connected at one end thereof by a ball-and-socket joint 19 to one end of an arm 17 which is in turn connected at the other end thereof to the coil carrying member M.
  • the lifting rod 18 is articulatingly guided at the other end 21 thereof in a bearing 22 secured to the intennediate wall 3.
  • the lifting rod H8 is formed with a pivot or swing guide bearing 20 located intermediate the ends thereof.
  • a pin 26 is moreover secured to the lever 23 on which one end of an adjusting rod 27 is pivotally mounted. The other end of the adjusting rod 27 is guided in the swing bearing 20.
  • a guiding pin 28 extends transversely from the adjusting rod 27.
  • a thread storage device 29 is provided at the winding station and is formed of a double-armed lever 40, which is pivotally mounted on a pin 33 extending from the intermediate wall 3 and carries a thread deflecting roller 34 at the end of one arm 30 thereof.
  • the other arm 31 of the doublearmed lever 40 is formed with an arcuate elongated guiding slot 32 into which the guiding pin 28 extending from the adjusting rod 27 projects.
  • thread guide rollers 35, 36 and 37 are also rotatably mounted on pins extending from the crosspiece 4.
  • a thread 38 is being applied by the thread guide 7 at the large diameter end of the cross-wound bobbin l3 and in the illustrated position, thread is provided with no additional loop by the thread deflecting roller 34 as shown in solid lines in FIG. 1.
  • the lever 33 then necessarily pivots into the position 23' thereof, also shown in phantom in FIG. 1.
  • the lever 23 accordingly displaces the thread deflecting roller 34 through the pin 26, the adjusting rod 27, the guiding pin 28, the guiding slot 32 and the anus 30 and 31 to the roller position 34 shown in phantom in FIG. 1.
  • a thread loop 39, shown in phantom in FIG. 1, is thereby formed and a length thereof is accordingly stored and cannot be wound up at the small diameter end of the bobbin 13 when the delivery speed of the tread 38 is constant.
  • thread storage means for compensating for varying speeds of thread being wound on a bobbin, a carrying member for the bobbin, means for automatically adjusting the length of the thread stored by said thread storage means in accordance with the degree of fullness to which the bobbin is wound
  • said thread storage means comprising a device for forming a loop of the thread, said loopforrning device having at least one member connected to said carrying member, and a thread guide reciprocable along the bobbin, the length of the loop being controllable in accordance with the position of the thread guide along the bobbin, said loop-forming device being connected to said thread guide in addition to said carrying member so that at a predetermined position of the thread guide along the bobbin, the loop has a constant length for any degree of fullness to which the bobbin is wound.
  • Coil winding machine wherein the carrying member for the bobbin is variable in position in accordance with the degree of fullness to which the bobbin is wound, and including a system of levers connecting said loopforming device to said thread guide, said system of levers having an effective lever arm length that is variable in accordance with the position of the bobbin member.
