Definitions

  • the present invention relates to ring spinning and twisting machines and, more specifically, concerns an automatically operable apparatus by means of which in connection with ring spinning and twisting, a reserve winding, a so-called upper winding, is imparted upon the tip of a cop.
  • an auxiliary motor is employed which, for purposes of applying the upper winding, shortens the pulling member on which the ring rails are suspended to such an extent that the ring rails can be lifted into the upper winding position.
  • the auxiliary motor is at a standstill and thus holds the ring rails in the upper winding position whereupon the auxiliary motor lowers the ring rails to their lower winding position by reversing its direction of rotation.
  • the tiltable arm which is oscillated by the cam for moving the ring rails and to which the pulling members actuating the ring rails are linked is actuated by a hydraulically, pneumatically or electromagnetically movable pull or pressure rod and is moved thereby beyond its normal tilting range to such an extent that the ring rails are lifted into the upper winding position.
  • the employed working element has to be designed rather strong. Consequently, a pneumatic or hydraulic working element becomes unduly expensive, whereas an electromagnetic working element will not assure a quiet uniformly fast lifting movement of the ring rails into their upper winding position.
  • FIG. 1 diagrammatically shows an end view of an arrangement according to the present invention for use in connection with a ring spinning machine.
  • FIG. 2 diagrammatically illustrates a side view of FIG. 1.
  • FIG. 3 illustrates the location of the upper winding on the cop.
  • FIG. 4 illustrates on a larger scale than FIGS. 1 and 2 a section through the upper winding apparatus which is shown in the lower portion of FIGS. 1 and 2.
  • FIG. 5 is a view of FIG. 4 an seen in the direction of the arrow A of FIG. 4.
  • FIG. 6 represents a section through a modified upper winding applying apparatus according to the invention.
  • FIG. 7 is a view of FIG. 6 as seen in the direction of the arrow B of FIG. 6.
  • FIGS. 8 and 9 respectively illustrate two control circuits for controlling the upper and lower winding operations.
  • the present invention is characterized primarily in that in addition to the cam which controls the building up of the thread layers (heart or layer eccentric) there is provided an additional cam which by means of its largest radius lifts the ring rails beyond the stroke range of the heart eccentric into the upper winding position.
  • This additional cam is rotatably mounted on the continuously rotating shaft of the heart eccentric and after completion of the build-up of the cop is adapted by means of a clutch to be connected to said shaft.
  • this clutch is designed as an electromagnetic clutch. The smallest non-effective radius of the cam disc for the upper winding is shorter than the smallest radius of the heart eccentric.
  • the cam disc for the upper winding extends over a peripheral portion of the so-called heart eccentric.
  • the cam disc for the upper winding device may according to a further development of the invention, following the engagement of the clutch first in view of its rotation act as cam disc and lift the ring rails into their upper winding position, whereupon the supporting roller of the tilting arm engages a ratchet, notch or the like on the cam disc, whereupon the clutch is disengaged and the cam disc acts as a stationary supporting member and holds the tilting arm in a position corresponding to the upper winding position.
  • the upper winding operation is, in conformity With the present invention, finished by the adjustable start of the lower winding operation which is initiated by an adjustable length or timer mechanism or by an adjustable cam on a continuously rotating part of the spinning or twisting machine.
  • FIG. 4 the wall 1 of the end support of the ring or twisting machine a (FIG. 4) has mounted thereon a bearing: bushing 2 in which a shaft 3 is journalled. Shaft 3 is driven in a standard manner by the transmission of the machine through the intervention of a pair of bevel gears 4, 5. Shaft 3 has a collar 6 to which a cam disc 7 is connected which is adapted through the intervention of a roller 8 to actu- 'ate a tilting arm 9 (see also FIG.
  • the tilting arm 9 carries a sprocket 10- over which a chain 11 passes from an indexing or control mechanism 12 over a guiding pulley 13 to a sprocket 14.
  • a sprocket 10- over which a chain 11 passes from an indexing or control mechanism 12 over a guiding pulley 13 to a sprocket 14.
  • sprocket 14 mounteded on the same shaft 15 to which sprocket 14 is keyed, there are also keyed sprockets 16 and 17 over which pass additional chains 18; chains 18 extend via deviating pulleys 1? to the lower ends of lifting bars 21 on which the ring rails 22 rest.
  • roller or pulley 8 on arm 9 Due to the weight of the ring rails 22, roller or pulley 8 on arm 9 always engages cam disc 7.
  • the circumferential shape of the cam disc 7 is so selected that when shaft 3 rotates, the ring rails will be raised and lowered in the desired manner.
  • Control mechanism 12 contains a reversible motor 51 which will draw chain 11 into the mechanism to shorten the chain or feed the chain out of the mechanism to lengthen the chain.
  • a normally open clutch 23, 24 is arranged between the two cam discs 7 and 25 which act upon the relatively wide roller 8.
  • Clutch part 23 is keyed to shaft 3 while clutch part 24 is fixed to disc 25.
  • the effective circumferential portion of the second cam disc 25 has a radius which exceeds the largest radius of the first mentioned cam disc 7. This difference in the lengths of the radii, in consideration of the lever length effective during the stroke transmission corresponds to the distance 25 which is intended between the upper winding 27 to be applied and the upper edge of the cop windin 28.
  • the radius of the non-effective portion of the second cam disc 25 is shorter than the smallest radius of the first cam disc 7 so that the tilting range of the tilting arm 9 will not be limited during its actuation by the first cam disc 7.
  • the second cam disc 25 has a rising flank 29 which is located between the radial and tangential direction.
  • the arrangement according to the embodiment of FIG. 4 has a counterweight 30 mounted on cam disc 25.
  • This counterweight lifts the effective range of the cam disc 25 out of the tilting range of roller 8.
  • this is effected by a spring 31.
  • the second cam disc 25 has a ratchet or notch 32 which is engaged by roller 8 and by means of which cam disc 25 is held in its position.
  • cam disc 25 is normally in its inedective position (full line position in FIG. 5; dotted line position in FIG. 7), and is only moved into effective position where it engages roller 8 when clutch 23, 24 is energized.
  • the clutch is normally deenergized and disc 25 is in ineffective position. Energization of the clutch will connect disc 25 to shaft 3 and the disc will move to effective position in engagement with roller 8.
  • the disc 25 remains in effective position until a motor in mechanism 12 operates to lengthen chain 11 and drop arm 9 away from disc 25.
  • the electric circuit of FIG. 8 for controlling the above described arrangement according to the invention comprises a relay 33 which, through its blade 34, is adapted to make clutch 23, 24 effective and ineffective.
  • a blade 36 adapted to be closed by the length measuring mechanism 35 of the spinning or twisting machine, and also a switch 38 adapted to be closed by a cam 37 on cam disc 7.
  • a holding blade 39 of relay 33 Arranged parallel to said switches 36 and 38 is a holding blade 39 of relay 33.
  • a blade 40 which is adapted to be opened by energization of its relay 41.
  • this relay 41 In series with this relay 41, according to FIG.
  • a switch 48 with serially arranged relay 41 is arranged parallel to the self-holding switch 47.
  • Switch 48 is adapted to be closed by a time measuring or length measuring mechanism 49.
  • a blade 50 In series with said measuring mechanism 49 is a blade 50 which is adapted to be closed by relay 33.
  • Relay 41 is adapted to close a blade 52 which is serially arranged with the lower winding motor 51 in the indexing mechanism 12.
  • clutch 23, 24 When the cop has been built up, and it is intended to apply the upper winding, clutch 23, 24 is engaged.
  • this is efiected when the length measuring mechanism 35 arranged on the ring spinning or twisting machine, closes switch 36 located in the circuit for the relay 33, and a second switch 38 arranged in series with switch 36 is closed by a cam 37 on the first cam disc 7.
  • relay 33 When both switches 36 and 38 close, relay 33 is energized and remains energized through its holding blade 39 and energizes clutch 23, 24 through blade 34.
  • clutch 23, 24 will connect the second cam disc 25 in a precisely determinable angular position with regard to cam 7 with shaft 3 and, more specifically, so that the lifting or raising of the spindle rails by the first cam disc 7, will be steadily continued by [flank 29 of the second cam disc 25.
  • the clutch may, after roller 8 engages notch 37, be disengaged inasmuch as roller 8 will hold cam disc 25 in said position.
  • Such disengagement may be caused by a normally closed switch in series with blade 34 which is opened when roller 8 drops into notch 32.
  • the switch could be mounted on disc 25 (FIGS. 6, '7) and be actuated by arm 9 or roller 8.
  • FIG. 7 shows such a switch at 60 and the switch is also shown in FIGS. 8 and 9.
  • the end of the upper winding applying operation is de- H termined by a further switch 44 adapted to be actuated by an adjustble cam 43 on cam disc 7 a predetermined time after the actuation of switch 36 and before the high part of disc 25 of FIG. 5 runs off roller 8.
  • Blade 42 which is already closed by relay 33 serves for permitting relay 41 to be energized upon closing of switch 44 only when an upper winding operation brought about by energization of relay 33 is effective.
  • switch 44 is closed by cam 43, and relay 41 becomes energized, blade 42 of relay 41 brings about energization of lower winding motor 51 and lengthening chain 11,- causes a lowering of the ring rails 22 into the lower winding position.
  • the thread length of the upper winding 27 is determined by the angular distance between cam 37 and cam 43 on cam disc 7 in conformity with the circumferential speed thereof.
  • either circuit can be used with either of the FIGS. 4 and 5 or the FIGS. 6 and 7 modifications.
  • the disc 25 has a long raised part and turns throughout the top winding operation and is released when relay 33 is deenergized whereas with the FIGS. 6 and 7 modification, the high part of disc 25 can be shorter, the clutch 23, 24 is released when roller 8 drops into notch 32, and the disc is released when arm 9 and roller 8 drop due to lengthening of chain 11 as brought about by energization of motor 51.
