Definitions

  • My invention relates to spinning or twisting machines, or the like, or in fact, to any machine wherein thread is fed from feed rolls onto a plurality of spindles.
  • a textile twisting or spinning machine consistsof a number of spindles mounted vertically along the sides of the machine and one or more sets of rolls which feed yarn to the spindles at a definite rate.
  • the usual scheme of drive has been to drive the spindles from a cylinder extending the length of the frame by means of a tape going over the cylinder and then over a small pulley attached to the spindle. lhe rolls and the cylinder are driven from a common source suitably geared so that at all times a definite ratio is maintained between cylinder speed and roll.
  • the feed rolls have to be driven by a separate motor energized bythe same alternating current frequency as the main motor driving all the spindles and while this produces fairly good synchronization between spindle and roll during operation, it is way off during acceleration and deceleration.
  • An object of my invention is to provide a spinning or twisting machine, or the like, in which there must be good synchronization between the spindle and roll during not only normal operation but during acceleration and deceleration.
  • a more specific object of my invention is to provide a plurality of spindles with separate induction motors which spindles are individually belted to a common cylinder or rotatable means, the latter serving as the driving element of the feed rolls so that the cylinder is driven at a plurality of places longitudinally thereof, thereby involving a minimum slippage of the belts and providing almost absolute synchronization between the spindles and feed rolls at all times.
  • numerals I, 2 and 3 denote a plurality of spindles which are driven by motors M1,,M2 and M3, respectively, which motors are preferably 1 I squirrel cage induction motors energized by high frequency currents supplied by a polyphase source indicated by L1, L2, L3.
  • Each of the spindles has a pulley or whirl such as indicated by numerals such as 4, 5 and 6, around which is entrained a belt or tape such as indicated by numerals 1, 8 and 9, which belts are entrained also around a common cylinder It! or other suitable rotatable means.
  • the cylinder It drives a plurality of feed rolls including the front rolls ll through a system of gears indicated by numeral [2 and a suitable speed changer indicated by numeral l3. Thread or untwisted yarn is fed from a plurality of bobbins such as indicated by numerals Ma, Mb and 140 through the respective feed rolls through which they are stretched and fed onto the respective spindles. For example, one of the threads I5 passes through the front roll and is passed through a traveller is on a ring I! and finally onto the spindle I.
  • the possible field of application for the drive shown in the drawing is unlimited and includes spindles used in the manufacture of automobile tire cord, heavy silk or rayon tapestry yarns, or, in fact, any of the many heavy, hard twisted cords or yarns used in industry.
  • the same scheme may be applied to the wire covering and 'rubber covering (latex) industry.
  • a control system for textile machinery and I the like comprising, in combination, a plurality of spindles, a plurality of feed rolls for guiding threads supplied to the spindles, a rotatable member extending in juxtaposition with respect to each of said spindles and which is geared to said rolls for driving the same, each of said spindles having a belt entrained therearound and around said rotatable member so as to provide a plurality of power sources for flexibly driving said rotatable member and of said spindles and feed rolls.
  • a spinning or twisting machine including a thread feeding roll and a plurality of spindles supplied with thread fed from said feed roll, rotatable means for driving said feed roll, a separate driving motor for drivingeach spindle, a flexible coupling means for tying each spindle and said rotatable means in driving relationship so as to apply power thereto at as many points as there are spindles.
  • a cylinder geared to L said rolls for driving the same, a plurality of driving motors, one for each of the spindles, a flexible belt like coupling which entrains each of the spindles to the cylinder so as to impart driving power to said cylinder at a plurality of places longitudinally of the cylinder.
  • a cylinder geared to said rolls for driving the same, said spindles befor synchronous operation ing disposed longitudinally of said cylinder and at right angles to the axis thereof, a plurality of driving motors, one for each of the spindles, a flexible belt like coupling which entrains each of the spindles to the cylinder so as to impart driving power to said cylinder at a plurality of places longitudinally of the cylinder.
  • a machine for winding thread onto spindles comprising in combination, roll means, a plurality of spindles fed by thread from said roll means, rotatable means for driving said roll means, a plurality of squirrel cage induction motors, one for driving each of said spindles, a pulley on each of said spindles, a plurality of belts, one for each of said pulleys for entraining said pulley and said rotatable means, and a source of power for driving said motors synchronously, so as to apply power to said rotatable means at a plurality of points.
  • a control system for textile machinery and the like comprising, in combination, a plurality of spindles each having a pulley rigidly secured thereto, means including a pair of front rolls for guiding and tightening thread supplied to the spindles, rotatable driving means, a plurality of flexible belts, each entrained about one of said pulleys and about said driving means, a plurality of alternating current induction motors, each of which is mechanically coupled to one of said spindles for driving the same, a common source of constant frequency alternating current for energizing all of said motors, and transmission means for mechanically coupling said driving means to said front roll so that said front roll is driven by the power of said plurality of induction motors.
  • said driving means comprises a cylinder having its axis at right angles to the spindle axis and in juxtaposition with respect to said plurality of pulleys.
  • a control system for textile machinery and the like comprising, in combination, a plurality of spindles each having a pulley rigidly secured thereto, a plurality of rolls for guiding and tightening thread supplied to the spindles, rotatable.
  • driving means a plurality of flexible belts, each entrained about one of said pulleys and about said driving means, a plurality of alternating current induction motors, eachof which is mechanically coupled to one of said spindles for driving the same, a common source of constant frequency alternating current for energizing all of said'motors, and transmission means for mechanically coupling said driving means to said plurality of rolls'so that the latter will be driven 153' the power of said plurality of induction mo- 10.
  • said driving means comprises a cylinder having its axis at right angles to the spindle axes and in juxtaposition with respect to said plurality of pulleys.
