Definitions

  • a rocker arm which supports a lifting chain, and a wheel contiguous to the rocker arm.
  • the wheel is actuated during dofling and stopped immediately upon completion of its predetermined rotation, and first and second engaging elements on the wheel engage the rocker arm to slacken and tension the lifting chain in the desired manner.
  • FIG. 1 is a motion diagram of the yarn guide member during spining and the subsequent dofling
  • FIG. 2 is a side elevational overall view of an apparatus for imparting motions to a yarn guide member diagrammatically shown in FIG. 1;
  • FIG. 3 is a side elevational view of a portion of the apparatus of FIG. 2 on a larger scale
  • FIG. 4 is a view of the device of FIG. 3 from the opposite side;
  • FIG. 5 is a plan view of the device of FIGS. 3 and 4;
  • FIG. 6 is a front elevational view of another portion of the apparatus of FIG. 1 on the scale of FIGS. 2 to 4.
  • the ordinate indicates the level of a vertically reciprocating yarn guide member such as a ring rail
  • the abscissa represents time
  • the motion of the yarn guide member during spinning starts with a rise and fall motion between the points a and b gradually developing into a building motion through the points (I -b to a -b said motion being the known building motion.
  • the device of this invention initiates a motion of the yarn guide member for dofiing.
  • An ini- "ice tial descending motion takes place from the point e to the point e, followed by an ascending motion from the point e to the point f and a second descending motion from the point f to the point g.
  • the guide member is then transferred from the point g to the point a whereupon the next spinning motion starts between the points a -b
  • the afore-described motion of the yarn guide member permits the cop to be doffed by the motion of the yarn guide member itself in an automatic spinning or twisting machine expected to be manufactured in the future.
  • FIG. 2 to FIG. FIG. 6 The apparatus for actuating the afore-described motion of the yarn guide member is illustrated in FIG. 2 to FIG. FIG. 6.
  • the apparatus includes a wheel A and a rocker arm B which are inoperative during spinning but are actuated automatically during dofiing.
  • a signal for initiating movement of the wheel A and the rocker mm B may be derived in a conventional manner from an element (not shown) which moves with the yarn guide assembly D when said guide assembly reaches the point 0 in FIG. 1. It may also be derived from a counter (not shown) arranged to count the number of revolutions of a front roller assembly F when the cop reaches a predetermined size. It may further be derived from a timer (not shown) set for the time necessary for the formation of a predetermined size of cop, or the like.
  • An arm 86 on the pawl 85' is simultaneously caused to push a button 87 of a switch 88.
  • the switch energizes a motor 1 which drives the wheel A.
  • the wheel A is mounted on a common shaft 48 adjacent the rocker arm B, as shown in FIG. 2 to FIG. 5, and has two recesses 52, 52' for coupling engagement with said rocker ai m.
  • the arm B is coupled to the recess 52' as shown in FIG. 2, and the arm and rocker are motionless.
  • the rocker arm B rotates with the wheel A until one arm of a bell crank lever 47 best seen in FIG. 5 strikes a fixed abutment 46.
  • the bell crank lever is attached to the arm B by a pivot pin 45 and is pivoted about the pin by the abutment 46.
  • a coupling rod G is connected by a pin 43' to the other arm of the lever 47 and is guided in an aperture of the arm B.
  • the rod G is pulled axially from the recess 52 so as to uncouple the rocker arm B from the wheel A.
  • the rocker arm B then drops to its normal position shown in FIG. 3 in which a projection 49 on the arm B abuts: against a stop 51 on the machine frame.
  • the dropping of the rocker arm B slackens a lifting chain E (FIG. 2) one end of which is attached to a drum 35, whereas the other end is attached to a sector lever 61, and two inter-mediate parts of the chain are trained over a pulley '40 on the machine frame and a pulley 41 on the rocker arm.
  • the yarn guide assembly D is held in a raised position c by the tension of said chain.
  • the assembly D' starts descending, moving under its own weight from the point 0 to the point e as shown in FIG. 1.
  • the downward velocity of the yarn guide assembly and the distance over which it descends can be adjusted by selecting the dimensions of a dash pot 67 in which oil 69 passes through a hole 72 in a piston 66.
  • the piston is connected by a rod 64 and a pin 63 to an arm 62 of the sector lever 61.
  • a nut 65 is threaded on the rod 64.
  • the dash pot 67 is hingedly attached to a fixed base 71 by a pin 70.
  • the downward velocity of the yarn guide assembly is determined by the selected diameter of the hole 72, While the limit of downward movement can be adjusted by setting the position of the nut 65 on the rod 64. Downward movement of the assembly D causes the nut 65 to abut against the cap 68' of the dash pot and thus to stop the movement of the sector level 61.
  • the yarn guide assembly D includes a ring rail 78 carrying yarn guide rings in the usual manner, and a lifting rod 77 on which the rail 78 is mounted. Vertical movement of the rod is actuated by an arm 76 fixedly attached to a pulley 75 which is rotatably mounted on the machine frame. The two ends of an elongated tension member 74 are respectively fastened to the pulley 75 and to a pulley 73 fastened to the lever 61 for rotation about the pivot of the lever. The combined Weight of the guide assembly D and of the lever 61 keeps the member 74 under tension.
  • the recess 52' takes the place of the recess 52 in FIG. 2, and moves toward the position G at which the rod G enters the recess 52. Then the rocker arm B again moves up with the wheel A so as to raise the yarn guide assembly D.
  • the release of the switch 88 results in the reversal of the motor 1, which then drives a belt 2 in a direction opposite to the arrow shown in FIG. 2.
  • a train of gears 9, and 11 is connected to a gear 8 on a motor-pulley 3 driven by the belt 2.
  • the gear train rotates backwards so that a pawl 12 will ride idly on a ratchet wheel 13 fastened to the gear 11.
  • a worm 14 connected to the ratchet wheel 13 for joint rotation engages a worm gear rim on the wheel A.
  • the wheel stops, and the apparatus is again in the original position for spinning.
  • the motion of the yarn guide assembly D for dofiing is completed.
  • a pawl 4 on the motor-pulley 3 drivingly engages a ratchet wheel 6 so as to rotate a main drive shaft 5', which in turn rotates a cylindrical roller 7 and a gear 15 thereon.
  • the rotation of the gear 15 actuates the rotation of the front roller F through a train of gears 16, 17, 18 and 25.
  • the rotation of a Worm 19 driven by the gear 18 actuates a worm wheel 20, a vertical shaft 21, bevel gears 22 and 23, and a cam 24.
  • a roller 31 (FIG. 6) travels over the face of the cam so as to impart to a builder assembly the known building motion, which in turn is transferred to the yarn guide member for spinning motion.
  • the builder assembly includes a swinging bracket 32 on which the cam-follower roller 31 is mounted.
  • a shaft 33 on the bracket 32 rotatably supports a worm terclockwise direction about the axis of shaft 33, as viewed in FIG. 2.
  • the drum 35 is rotatably mounted on the shaft 33.
  • a spring 93 urges the two halves 91, 92 of a clutch interposed between the drum 35 and the worm wheel 34 into engagement.
  • An electromagnet 94 is provided for disen gaging the clutch against the spring action.
  • the worm 38 is gradually rotated in the direction of the arrow (FIG. 6) in a manner well known and therefore not illustrated, in order to shift the range of the reciprocating movement of the yarn guide assembly D from LI -b through a b toward 0 -12
  • the reciprocating strokes of this movement are actuated by the cam 24 which pivots the bracket 32 and thereby alternatingly tensions and relaxes the chain E trained over the drum 35.
  • the chain E is unwound to its original length from the drum 35 by an unwinding device.
  • a projection (FIG. 4) on the wheel A is provided for actuating a switch (not shown) which opens and closes the circuit of the electromagnet 94.
  • a switch not shown
  • the projection 95 closes the switch, and the drum 35 is disconnected from the worm wheel 34 by the electromagnet 94 which attracts its armature 96.
  • the drum 35 rotates under the weight of the lifting chain E until the length of the lifting chain E between the drum 35 and the sector lever 61 is restored as needed for spinning.
  • An apparatus for operating yarn guide means during doffing in a spinning machine and the like comprising, in combination:
  • first and second engaging means provided on said wheel member for selective engagement of said wheel member with said rocker arm member during two respective portions of said predetermined rotation, whereby said members move jointly while engaged when said wheel member is rotated by said actuating means.
