Definitions

  • This invention relates to textile machinery for processin slivers, roves, or yarns, such machines consisting of a series of stations each of which comprises first means, such as a drawing device, for feeding second means, such as a spinning spindle, the first means of each station being driven by a common drive means, an example being a shaft co-extensive with the full length of machine.
  • This invention has for its object to provide means for individually preventing each drawing device from continuing to feed its associated spindle after the rove has broken therebetween.
  • eachstation is provided with a separate stop motion device activated upon asliver, rove or yarn breaking, which is positioned between the drawing device and the spindle device and which controls means for stopping feeding of the sliver, rove or yarn in the station concerned without halting the advance of said sliver, rove or yarn in the other stations.
  • the link between the first device of each station and the common drive means referred to preceding comprises a coupling releasable in response to actuation of an individual stop' motion device each time a break occurs.
  • each coupling comprises a driving dog which is rigidly connected to a part keyed to said shaft and which drive a pawl pivotally connected to a plate which is in turn coaxially pivotable on a.
  • FIGURE 1 shows in plan View, with cutaway portions, a part of the drawing device of the machine, the upper intermediate pressure rolls and the sleeves thereof having been removed for greater clarity,
  • FIGURE 2 is a section taken through the line IIII of FIGURE 1,
  • FIGURE 3 is a section taken through the line III-III of FIGURE 1,
  • FIGURE 4 is a partial section taken through the line IVIV of FIGURE 3, and
  • FIGURE 5 shows a detail of FIGURE 3.
  • the continuous spinning machine fragmentally illustrated thereon .comprises a number of drawing stations such as P1, P2, etc., only two stations being shown in the drawing.
  • Each station has three lower splined rolls 1, 2, 3, which cooperate with three smooth upper pressure rolls 4, 5, 6, respectively.
  • On rolls 2 and 5 are mounted two sleeves 7 and 8, respectively.
  • Reference numeral 10 designates the rove of textile fibres passing into the drawing station.
  • the three upper pressure rolls 4, 5 and 6 of the drawing station P1 are mounted on shafts common to the corresponding three upper pressure rolls of the adjacent station P2, the three shafts being carried on a common pressure arm 12 pivotally mounted on the machine frame, whereby it may be raised if necessary in order to enable the upper rolls to be moved away from the lower rolls.
  • the three pressure rolls 4, 5 and 6 are freely rotatable and are frictionally driven by the cooperating positively driven lower rolls.
  • All the lower drawing or exit rolls of each station (such as the rolls 1) are accordingly mounted on a common drive shaft 14 which is coextensive with the machine throughout its entire length and is driven by any convenient power means (not shown).
  • each station (such as the rolls 2 and 3) are driven through a special transmission system by a further shaft 15 which is likewise coextensive with the full length to the spinning machine and which is permanently coupled to the shaft 14 through a train of gears 16, 17, 18, 19 (see FIGURE 1).
  • the total number of gearwheels in this train is an even number
  • gearwheel 23 which meshes simultaneously with two gearwheels 24, 25 (see also FIGURE 2) rigidly connected to the lower rolls 2, 3, respectively.
  • a drum 27 is mounted on the sleeve 22 and is rendered rigid therewith by longitudinal pegs 29 which extend through a collar 31 of sleeve 22'and penetrate into notches on the corresponding face of the hub of said drum.
  • the drum 27 is positioned axially on sleeve 22 by an elastic keeper-ring 33 located in a corresponding groove formed in the outer cylindrical surface of said sleeve and bearing against the other face of said drum hub.
  • a disc 35 which is rendered rigid with the shaft 15 by a key 36, carries one or more dogs 38 (shown as numbering two in the illustrated example) normally in en gagement with a pawl 41 pivotally mounted on a pin 42 rigidly connected to a plate 28 which is mounted loosely on the hub of drum 27.
  • the pin 42 extends with a large clearance through a wide opening 43 formed in the web of drum 27.
  • the end of the pawl 41 remote from its pivot carries a follower 45 engaging with a radial cam groove 46 which is likewise formed in the hub of drum 27 (see also FIG- URE).
  • the drum 27 is urged to rotate in the opposite direction to the arrow 1 relatively to the plate 28, by a return spring 48 one of whose ends is fastened to a stub 49 rigid with plate 28 and the other end to .a stub 51 rigid with drum 27.
  • the periphery of plate 28 has formed thereon notches 53, with which a retractable stop 54 is adapted to engage whereby to prevent rotation of said plate.
  • this stop When this stop is in the inoperative position shown in solid lines in FIGURE 3 it allows the plate 28 to rotate freely, whereas when it is in its operative position shown in broken lines it engages with one of said notches and prevents rotation of said plate.
  • the retractable stop 54 is actuated by a mechanical or (as assumed herein) electromagnetic system governed by a stop motion device responsive to a rove-breaking 56, which comprises an electric contact 61 activated by a feeler 57 terminating in a rove guide 58. On issuing from the drawing station the rove runs over a guide 59 before passing through the rove guide 58.
  • the electromagnetic device 55 for actuating the retractable stop 54 basically comprises an electromagnet 63 whose moving core 64 is connected through a link 65 to an extension of the retractable stop 54, which stop pivots about a pin 66.
  • a retractile spring 68 urges the stop 54 into its inoperative retracted position, while on being energized the electromagnet moves said stop into its lower operative position against the bias of said spring.
  • the coil of electromagnet 63 is energized by a suitable source of current S, under control of the stop motion device eleotric contact 61.
  • the primary drive shaft 14 which rotates continuously, in turn continuously rotates the shaft through the train of gears 16, 17, 18, 19.
  • the rove 10 when normally fed between the drawing device and the spinning spindle, exerts a uniform pressure on the yarn-guide 58 of feeler 57, whereby the stop 54 is maintained in its retracted position and one of the dogs 38 of disc 35, which rotates in the direction of arrow f1 moves the pawl 41 along with it.
  • the pawl 41 Being pivotally mounted about the pin 42, the pawl 41 rotates the plate 28 and, through the agency of spring 48, also rotates the drum 27 and the sleeve 22 rigid therewith.
  • the gearwheel 23 rigid with said sleeve is thus made to rotate the lower restraining and feed rolls 2 and 3, respectively, of the drawing station.
  • the return spring 48 tends to rotate drum 27 in the opposite direction to arrow f1 relatively to the plate 28, i.e. relatively to the pawl, thereby causing the cam 46 of said drum to tend to make the pawl 41 pivot outwardly, i.e. in the direction whereby it is kept engaged with the dog 38 driving it.
  • a drawing device for a spinning machine of the type which includes a continuously operative drive shaft; at least one roll driven by said shaft; and stop motion means interposed between said shaft and said roll for interrupting the output of said drawing device
  • said stop motion means comprises: a driving member fast on said shaft, a driving dog fixedly secured to said driving member, a drum freely rotatably mounted on said shaft, said drum being continuously connected to drive said roll, a circular plate member freely rotatably mounted on said drum coaxially therewith, a pawl pivotally mounted on said plate member and normally engaging said dog to be driven thereby, cam means carried by said drum for controlling said pawl, resilient means interconnecting said drum and said plate member and yieldingly urging said cam means to maintain said pawl in driving engagement with said dog; sensing means at the output of said drawing device, said sensing means being responsive to breakage of the product emerging from said drawing device; and stop means controlled by said sensing means, said stop means acting on said plate member to stop rotation thereof and thereby actuate
  • said drum includes a web portion intermediate its hub and its periphery, said web portion having an elongated slot formed therein which extends generally radially with respect to the rotational axis of said drum, said cam means comprising the lateral edges of said slot and a cooperating follower member slidable longitudinally of said slot and engageable with said lateral edges.
  • said sensing means includes electrical contact means, in which said stop means comprises an electromagnet controlled by said contact means and a stop member actuated by said electromagnet, said plate member carrying means en- 5 6 gage able with said stop member to stop said rotation in 1,462,896 7/1823 Barksdale et a1 57-83 response to said breakage of said product.
  • said stop means comprises an electromagnet controlled by said contact means and a stop member actuated by said electromagnet
