Definitions

  • This invention relates to the twistingjof textile yarns and more particularly to a device to sense ends down.
  • An important object of the invention is the provision of a ring frame control device for sensing ends down which will operate electrically and which will not engage the textile strand being produced.
  • Another object of this invention is to provide a control device for indicating ends down using the ring and the traveler positioned at rest, following a stretching or breaking of the textile strand for actuating a mechanism sensing the ends down condition.
  • Another object of this invention is to reduce labor costs by providing a signaling device which will show the operator where attention is needed so that the search for ends down will be minimized.
  • Another object of the invention is to provide a sensing device for indicating ends down which does not contact the textile strand.
  • Still another object of this invention is the provision of electrical sensing means which may serve as a counting mechanism indicating the number of ends down.
  • Figure 1 is a perspective view showing a ring frame and the like having a device constructed in accordance with the present invention shown therewith,
  • Figure 2 is an enlarged transverse sectional view taken through a twisting ring and holder as shown in Figure 1,

  • Figure 4 is a transverse sectional view similar to Figure 3 showing a device constructed innaccordance -witli a modified form of the invention.
  • Figure 2 shows a twisting ring which includes a contact or con,- ductor element A which will be contacted by the traveler B when the yarn breaks or becomes slack. causing the traveler to fall into contact with the upper surfaces. of the twisting ring C.
  • the conducting portion A is in: sulated from the ring C which is grounded throughthe. twisting ring to the frame of. the. machine.
  • The. conducting portion A is electrically connected to another conductor D.
  • a sensing circuit E. is; connectedacross the conductor D and ground and it will be noted that the falling of the traveler B due to an ends down con? dition will result in the closing of the circuitlbetween the conductor D and ground across the sensing circuit E which will then serve as a control for the ends down condition.
  • Figure 1 shows a ring frame and the like with which the ends down control device of the present inventionlis adapted to be employed.
  • The. frame is indicated at 10 and has a suitable creel arrangement 11 positioned longis tudinally along the top thereof carryingroving or yarn packages 11a.

  • the bobbins '14 are positioned upon the spindles 15 and project upwardly through a ring rail 18.
  • the ring rail 18. is essentially a channel shaped memher having its arms projecting downwardly and having a plurality of spaced circular holes 18a therein for accommodating a twisting ring holder 19.

  • the holder 19 is an annular ring having a groove 19c in the inside top portion thereof for accommodating a twisting ring C which is substantially I-shaped in cross section.
  • the ring C has a lower flange 21, avertical web portion 22 and an upper flange 23 integral therewith.
  • the upper flange 23 serves to confine the traveler B V thereon as it travels around the ring C.
  • the traveler-B- includes an annular portion 24 and a pair of inwardly projecting legs 25 and 26 which pass beneath the upper. flange 23.
  • the traveler B is normally held in a raised position as shown in Figure 2 and serves as a guide for the yarn as it is wound upon the bobbins '14.
  • the conducting element A of the present invention is shown in Figure 2 as being an annular portionx23a which forms the outer portion of thefiange 23 and which, is electrically insulated by suitable material '27 from the remainder of the ring C.
  • the insulating material 27 is shown in Figure 2 as being an annular portionx23a which forms the outer portion of thefiange 23 and which, is electrically insulated by suitable material '27 from the remainder of the ring C.
  • the insulating material 27 is shown in Figure 2 as being an annular portionx23a which forms the outer portion of thefiange 23 and which, is electrically insulated by suitable material '27 from the remainder of the ring C.
  • the insulating material 27 is shown in Figure 2 as being an annular portionx23a which forms the outer portion of thefiange 23 and which, is electrically insulated by suitable material '27 from the remainder of the ring C.
  • the con ⁇ ducting element D may be secured to any suitable. portionv of the ring rail 18 and is shown secured tothe.
  • The'ring C is electrically connectedto ground, it this case the frame of the machine, so that it is evident that if a textile strand being wound upon a bobbin 14 breaks that the traveler B will fall against the upper portion of the ring C so thatthe traveler will then serve asa conducting element bridging the annular conducting element A, which is connected to the conductor D, and the remainder of the upper flange 23 which is connected to ground through the ring C.
  • the sensing circuit E which is thus connected across the conductor D and ground to serve any desirable useful function in the control of an ends down condition, becomes actuated.
  • the sensing circuit E includes a primary coil 32 which is supplied with a source of electrical energy through the double switch 31 and suitable fuses 31a which are shown connected in series with the switch 31.
  • a secondary coil 33 is shown in inductive relation to the primary coil 32.
  • the secondary coil 33 is positioned across ground and the low potential side of a relay coil 34 which operates the switch 35.
  • the switch 35 is provided to insure an effective closing of the circuit while the switch 36 is provided to place the light or any suitable signaling means 37 and the like across the primary circuit.
  • a coil 38 may be placed in parallel With the light 37 to operate a counting mechanism R. If desired, a stop motion device (not shown) could be actuated in lieu of the signalling means shown to stop the machine upon the occurrences of an ends down condition.
  • Figure 3 shows a device constructed in accordance with a modified form of the invention in which like reference characters are used to refer to like parts with prime notations added.
  • the ring C is divided substantially down the middle to provide an inner annular portion 40 and an outer annular portion 41.
  • the inner annular portion 40 is insulated from the outer annular portion 41 and the holder 19' by the insulation 42.
  • the inner annular portion 4% forms the conducting element of this embodiment of the invention and is shown in electrical connection with a power connection through a spring contact 43.

  • FIG 4 shows another modified form of the invention in which the conducting element is shown in the form of an annular ring 50 carried by the outer portion of the vertical web 22" of the ring C".
  • the annular conducting element 50 is suitably insulated from the ring by the insulation 51.
  • An inner annular ring 52 is provided and is insulated from the ring C" by the insulation 52a and serves to impart a carnming action against the traveler B" so as to cause engagement between the outer ring 25 and the conductor 50 when an ends down condition occurs.
  • the conductor element 50 is connected to a power connection through a spring contact 53 while the camrning ring 52 is grounded through a spring contact 54 which is carried by the inner portion of the holder 19" by the screw 55.
  • the sensing circuit could actuate suitable signals preferably in the form of a light as shown herein which may be located so as to signal both the bay and the particular ring frame where an ends down condition has occurred. Signals could also be ar ranged to indicate the side of the ring frame involved so as to further limit the searching of the operator.
  • counting mechanisms can be employed to provide a record of the number of ends down. The operator may simply piece a textile strand together and the frame operation continued. This is an important factor because the operator will not have to become accustomed to piecing the yarn in a different fashion than that to which he has already become accustomed.
