Definitions

  • An improved flyer assembly for twisting a strand of material in either of two directions and winding the twisted strand of material onto a spool includes a pair of capstans which are rotated about a central axis of the flyer assembly to twist the strand.
  • a floating guide wheel or roller guides the strand from the central axis of the flyer to one of the capstans.
  • the guide wheel is freely movable between a first position in which the strand is initially fed to one side of a capstan and a second position in which the strand is initially fed to the opposite side of the capstan. If the strand should break during a twisting operation, the end portion of the length of strand leading to the spool is held against one of the capstans by a retainer roller to prevent spilloff and whipping movement of the strand.
  • This invention relates generally to an improved flyer assembly and more particularly to a flyer assembly having improved strand guide and retaining assemblies.
  • a changing of the direction in which the strand is wound about the capstans involves changing the position of a guide wheel relative to the capstans.
  • the changing of the position of this guide wheel is a relatively complicated procedure which involves the disconnecting of a plurality of fasteners and a physical dismounting and remounting of the guide wheel.
  • this requires interrupting operation of the flyer assembly for a relatively long period of time whenever the direction of strand twist is to be reversed.
  • the strand may break.
  • the high speed rotation of the flyer assembly and takeup spool causes the end of the strand to whip around during continued rotation of the flyer assembly and takeup spool.
  • This is not only dangerous but can also result in the wire becoming entangled in a maze around the twister apparatus.
  • the cutting away of this maze of entangled wire is a time consuming process which substantially impedes efficient operation of the twister apparatus.
  • the present invention provides an improved flyer as sembly having a floating guide wheel which moves in an unrestrained manner between a first position conducting a strand to one side of a capstan and a second position in which the guide wheel conducts the strand to the opposite side of the capstan to facilitate changing the direction in which the strand is wound around the capstans when the direction of strand twist is to be reversed. Since the guide wheel moves in an unrestrained manner, whenever the direction of twist of the strand is to be reversed it is merely necessary to slide the guide wheel from one position to another as the direction in which the strand is wrapped around the capstans is reversed.
  • the flyer assembly includes a retainer roller which presses the strand against one of the capstans to prevent spilloff and whipping of the strand in the event the strand should break during a twisting operation.
  • Another object of this invention is to provide a new and improved flyer assembly for twisting a strand of material in either one of two directions and which includes a guide assembly for guiding movement of a strand of material to a first side of a capstan when the strand of material is being twisted in one direction and for guiding movement of the strand of material to a second side of a capstan when a strand of material is being twisted in the opposite direction and wherein a support arrangement enables the guide assembly to move in an unrestrained manner between the first and second positions to facilitate a reversal in the direction of twisting the strand.
  • Another object of this invention is to provide a new and improved flyer assembly for twisting a strand of material and which includes a capstan against which a portion of the strand is pressed by a retainer member to hold the strand against undesired movement in the event of a break in the strand during a twisting operatlOn.
  • FIG. 1 is a schematic illustration of a wire twister having a flyer assembly constructed in accordance with the present invention
  • FIG. 2 is a plan view, taken generally along the line 2-2 of FIG. 1, illustrating the relationship between a pair of capstans, a floating guide wheel for conducting a strand of material to the capstans, and a retainer roller which holds an end portion of a strand of material against whipping movement in the event of a break in the strand; and
  • FIG. 3 is a fragmentary sectional view, taken generally along the line 3-3 of FIG. 2, further illustrating the relationship between the floating guide wheel and the capstans of the flyer assembly.
  • a twister assembly 10 for twisting wire and other material into strands is illustrated schematically in FIG. 11.
  • the twister assembly 10 includes a guide or lay plate 12 through which a plurality of wires 14 extend from a suitable creel.
  • a secondary or pre-twister assembly 16 twists the wires 1A in either the S or Z directions to form a strand 20.
  • the secondary twister l6 overtwists the wires in the strand 20.
  • the strand is then partially untwisted or relaxed by a primary or main twister 24 which neutralizes or removes any inherent tendency for the strand to twist upon being released to thereby provide a neutral or dead strand in a manner similar to that described in U.S. Pat. No. 2,526,247.
  • the primary twister 24 includes a flyer assembly 26 which is rotated in either one of two directions to twist the strand 20 and to thereafter wind the strand on a take-up spool or reel 30.
  • a flyer assembly 26 which is rotated in either one of two directions to twist the strand 20 and to thereafter wind the strand on a take-up spool or reel 30.
  • the primary twister 24 and flyer assembly 26 can be driven directly, in the specific embodiment of the invention illustrated in FIG. 1 the take-up reel 30 is driven by a motor 32 to drive the primary twister 24 and flyer 26 in a known manner.
  • a control assembly 34 provides a precise control of the velocity ratio between the pretwister l6 and primary twister 24.
  • the control assembly 34 is constructed in the manner disclosed and claimed in application Ser. No. 143,416, now U.S. Pat. No. 3,685,271 filed by Charles A. Wall and F. Norman Lutz on May 14, 1971 and entitled Wire Twister.
  • the strand is held and twisted by rotation of a main capstan 40 and a secondary capstan 42 about the central axis 46 (FIG. 1) of the primary twister 24 and flyer assembly 26. It should be noted that the strand 20 moves through the primary twister 24 along a path which is coincident with the central axis 46 of the primary twister and takeup spool 30. As the flyer assembly 26 is rotated about its central axis 46, the capstans 40 and 42 grip or hold the strand 20 so that it is twisted as the flyer assembly rotates.
  • the capstans 40 and 42 are also rotated about their own central axes to feed the strand 20 from the capstans to a flyer arm 50.
  • the flyer arm 50 rotates about the central axis of the spool 30 to wind the twisted strand 20 on the spool.
  • the flyer assembly 26 and primary twister 24 are driven in a known manner by rotation of the spool 30.
  • the spool 30 is driven by the motor 32 to pull the strand 20 from the flyer arm 50.
  • the flyer arm applies a torque or turning moment to a base 54 of the flyer assembly 26 to rotate the base of the flyer as sembly about the central axis 46.
  • a drive train 56 (FIG. 1) is driven by this rotational movement of the base 54 to rotate the main or central capstan relative to the base 54 and feed the strand 20 from the capstans 40 and 42 to the flyer arm 50.
  • the direction of rotation of the base 54 and takeup spool 30 is reversed when the direction of twist of the strand 20 is to be reversed.
  • the base 54 and capstans 40 and 42 are rotated in one direction about the central axis 46 when a Z twist is to be applied to the strand 20 and in the opposite direction when an S twist is to be applied to the strand.
  • reversing the direction of rotation of the base 54 reverses the direction in which the drive train 56 is driven. Reversing the direction in which the drive train 56 is driven results in a reversal of direction in which he capstan 40 is driven relative to the base 54 by the drive tram.
  • the direction of rotation of the capstan 40 is reversed with a change in the direction of twist of the strand 20, the direction in which the strand 20 is wrapped around the capstan 40 must be reversed in order to provide for a proper feeding action to and from the capstan.
  • the capstan 40 is rotated in a counterclockwise direction (as viewed in FIG. 2) by a drive shaft 58 (FIG. 3) connected to the drive train 56.
  • the strand 20 then is fed from the capstan 40 along a path indicated in dashed-dot lines and through a passage 60 to the flyer arm (FIGS. 2 and 3).
  • the drive train 56 rotates the capstan 40 in a clockwise direction (as viewed in FIG. 2) so that the strand 20 is fed along the path indicated in dashed-double dot lines and through a passage 62 to the flyer arm 50.
  • the capstan 42 is freely rotatable on bearings 66 (FIG. 3) so that it is rotated by the strand 20 in the same direction that the main capstan 40 is rotated by the drive train 56.
  • the drive train 56 (FIG. 1) rotates main capstan 40.
  • the main capstan 40 pulls the strand 20 around the secondary or idler capstan 42 to drive the secondary capstan in the same direction.
  • the strand 20 As the strand 20 is pulled from the primary twister 24 it passes over a floating guide wheel or roller 74 to the secondary capstan 42. The strand is wrapped part-way around the secondary capstan 42 and then extends over to the primary capstan 40. After the strand has been turned around the primary capstan 40, it is wound back around the secondary capstan 42. As the strand passes between the primary and secondary capstans 40 and 42, it moves along the paths indicated with dashed and triple-dot lines in FIGS. 2 and 3. After being wrapped for a plurality of turns around the capstans 40 and 42, the strand 20 extends from the capstan 40 through one of the two passages 60 and 62 to the flyer arm 50.
  • the direction in which the strand is wrapped around the capstans must be reversed when the direction of rotation of the capstans is reversed.
  • the capstan 40 is being driven in a counterclockwise direction (as viewed in FIG. 2) relative to the base 54, the strand 20 moves from a central passage 78 which extends through the primary twister 24 and flyer assembly 26 (see FIGS. 2 and 3), across the floating guide roller 74 to the left-hand side (as viewed in FIG. 2) of the secondary capstan 42.
  • This path of the strand 20 indicated in FIGS. 2 and 3 with dashed-dot lines.
  • the strand 20 is then wound about the capstans 40 and 42 in their common direction of rotation (counterclockwise in the present example).
  • the strand 20 is turned in a counterclockwise direction (as viewed in FIG. 2) about the secondary capstan 42.
  • the strand 20 After extending around the secondary capstan 42 for approximately the strand 20 extends to the right-hand side (as viewed in FIG. 2) of the main capstan 40.
  • the strand then extends around the main capstan 40 for approximately 180 in a counterclockwise direction to the lefthand side (as viewed in FIG. 2) of the main capstan.
  • the strand then passes back to the left-hand side (as viewed in FIG. 2 of the secondary capstan 42.
  • the strand After being wrapped around the primary and secondary capstans 40 and 42 for a number of times in this manner, the strand passes from a bottom or innermost groove 82 in the main capstan 40 to the passage 60.
  • the strand 20 When the capstans 40 and 42 are rotated in a clockwise direction, the strand 20 is wound so as to extend from a central passage 78 to the right-hand side (as viewed in FIG. 2) of the secondary capstan 42 along the path indicated in dashed-double dot lines in FIG. 2. The strand then passes in a clockwise'direction about the secondary capstan 42 to the left-hand side (as viewed in FIG. 2) of the main capstan 40. The strand then passes around the main capstan 40 in a clockwise direction to the right-hand side (as viewed in FIG. 2) of the capstan and back to the right-hand side of the secondary capstan 42. After the strand 20 has been wrapped for a plurality of times about the capstans 40 and 42 in this manner, the strand extends from the lefthand side (FIG. 2) of the main capstan 40 through the passage 62 to the flyer arm 50.
  • the free floating guide wheel 74 must be moved when the direction of strand twist is reversed.
  • the guide wheel 74 is positioned to guide the strand 20 to the left-hand side of the capstan 42, along the path indicated by dashed and dot lines.
  • a circular groove 86 in the guide wheel is aligned with the central axis 46 of the passage 78 and main twister 24.
  • the groove 86 engages the strand 20 and guides it axially and radially outwardly of the main capstan 40 toward the lefthand side of the secondary capstan 42.
  • the guide wheel 74 is positioned to guide the strand 20 to the right-hand side of the capstan 42, along the path indicated by dashed-double dot lines in FIG. 2.
  • the circular groove 86 in the guide wheel engages the strand 20 at the central axis of the passage 78 and guides the strand axially and radially outwardly of the main capstan 40 to the right-hand side (as viewed in FIG. 2) of the secondary capstan 42.
  • the guide wheel 74 is pivoted about the central axis 46 of the main capstan 42 as it moves between the positions shown in solid and dashed lines in FIG. 2. This enables the groove 86 to be in alignment with the central axis 46 of the capstan 40 and flyer assembly 26 in both positions.
  • the guide wheel 74 is mounted for unrestrained pivotal or rotational movement about the central axis of the tlyer assembly 26.

  • the high-speed rotation of the flyer arm 50 and spool 30 tends to whip the free end of the strand around.
  • the free end of the strand whips around, it may form a tangled maze or jungle of wire around the twister assembly 10 and take-up spool 30.
  • This tangled maze must be removed from the twister assembly 10 before twisting operations can again be resumed.
  • the whipping or rapidly moving end of a broken strand 20 represents a substantial danger to any personnel who may be in the area of the twister assembly 10.
  • a retainer assembly presses a portion of the strand 20 against the main capstan 40.
  • the retainer assembly 110 is advantageously mounted on the base 54 adjacent to a lowermost portion of the main capstan 40 so that the strand is pressed against the arcuate surface of the lowermost groove 82 (see FIG. 3) in the capstan 40. With the retainer assembly 110 disposed in this position, the free end of the strand 20 will be gripped even though a short length of the strand is wound on the spool 30 after the strand breaks.
