Definitions

  • Windups which include a print or drive roll to which yarn advances from a reciprocating traverse guide and from which the yarn is deposited on a surface driven package are in wide use. To avoid waste during a dofling cycle, such windups have been modified by the provision of two rotatable package supports alternately movable into surface driven engagement with the drive roll and of auxiliary equipment for accomplishing transfer of the yarn from a full package to a driven empty support.
  • the present invention is directed to such a windup and has as its principal objective the provision of further improvements and modifications with which the transfer of yarn to an empty package support is not only accomplished automatically but also in a more uniform and reliable fashion. It is a particular objective of the invention to provide for positive control of the yarn during a transfer cycle.
  • a corollary object is to provide for the direct transfer of yarn from a full package to an empty support with a minimum of waste.
  • a windup which includes a drive roll, a pair of rotatable chucks alternately movable into surface engagement with the drive roll, a reciprocating traverse guide through which yarn normally advances over the drive roll to a package support on the driven chuck and an automatic mechanism for transferring the yarn from a full package to an empty package support.
  • the transfer mechanism includes an elongated deflector bar which has a guide at one end and which is pivotally mounted at its other end for swinging movement to a position adjacent an empty support on the driven chuck. When in position, the bar is slidable to a location of alignment with severing elements on the driven chuck. After the yarn has been deflected and severed, a transfer tail is wound and a new package is initiated on the empty support.
  • FIGURE 1 is a side view of a windup into which the transfer mechanism of the present invention has been incorporated;
  • FIG. 2 is a fragmentary front view of the windup
  • FIG. 3 is a side view of the transfer mechanism shown in FIG. 1;
  • FIG. 4 is a sectional view taken on line IVIV in FIG. 3;
  • FIG. 5 is a longitudinal sectional view taken on irregular line VV in FIG. 3;
  • FIGS. 6 and 7 are top and front views, respectively, of the transfer mechanism.
  • FIG. 8 is a schematic illustration of the windup.
  • the windup chosen for purposes of illustration includes generally, as components thereof, an equipment frame 10, a pair of articulated swing arms 12, 14 mounted for relative rotation about a common pivot 16, rotatable chucks 18, 20 on stub shafts at the extremities of arms 12, 14, a drive roll 22, a reciprocating traverse guide 24 through which yarn 26 advances over drive roll 22 to a package 28 on chuck 20, and a transfer mechanism 3t).
  • a piston and cylinder assembly 32 and coupled linkages are actuated to release a pawl 34 and to prepare the illustrated cams for descent of arm 14 to a point where the stub shaft rests on a cradle 36.
  • a piston and cylinder assembly 38 is actuated to withdraw a brake shoe 40, against the bias of a spring (not shown) so that chuck 20 will continue to rotate and take up yarn when it reaches the position shown in phantom at 20.
  • a piston and cylinder assembly 41 is actuated to pivot a latch 42 clockwise, thereby releasing arm 12 from its ready position to one in which an empty support tube 44 on chuck 18 is in surface driven engagement with drive roll 22.
  • the descent of package 28 trips a switch 46 to initiate pivotal movement of mechanism 30 to a level position (FIG. 3) beneath drive roll 22 and the then driven but empty package support on chuck 18.
  • mechanism 30 is returned to the position shown in FIG. 1 and brake shoe 38 rises into engagement with chuck 20'.
  • arm 14 is unlatched at 48 and swung further to the ready position, i.e., to the position shown for arm 12 in FIG. 1. In the meantime, a package is being built on chuck 18.
  • FIG. 2 the stub shaft on which chuck 20 is rotatably mounted has been shown at 50. It is the illustrated length of shaft 50 which engages cradle 36 when the chuck is at position 20'.
  • Chuck 20 has a groove 52 cut in its surface adjacent the location of support tube 44.
  • v Chuck 18 is similarly equipped. Within each groove 52, there are several V-shaped snaring elements 54 and angularly disposed severing elements 55 which function to snare and sever yarn 26 at the initiation of a package.
  • a transfer tail of one or more helical wraps is wound as yarn 26 is traversed to the package area on tube 44.
  • Yarn transfer mechanism 30 has been shown in detail in FIGS. 3-7 and schematically in FIG. 8.
  • mechanism 30 has a frame 56 fixedly attached to a tubular housing 58 which is rotatably mounted on equipment frame 10.
  • frame 56 On frame 56, there is a slidably mounted yarn deflector bar 60. Intermediate its ends, bar 60 carries a holder 62.
  • housing 58 Attached to housing 58, as shown at 59, there is a piston and cylinder assembly 64 which functions to swing frame 56 and bar 60 from the position shown in FIG. 1 to the operable position of FIG. 3 when air under pressure is supplied through con duit 66.
  • the cylinder of assembly 64 has its lower end vented to the atmosphere, 'as shown at 65 in FIG. 8.
  • air from conduit 66 is delivered to housing 58 through a conduit 70, as described more fully in connection with FIGS. 5-8.
  • holder 62 has a pair of spaced upright plates 72 between which a latch 74 having a tooth 76 is pivotally mounted at 78.
  • Latch 74 is biased to the position shown in FIG. 4, with tooth 76 projecting beyond edges 86 on plates 72, by a permanent magnet 82.
  • tubular housing 58 there is a ball bearing 84 (FIG. 5) which supports the swingable parts of transfer mechanism 30 rotatably on a short shaft projecting from equipment frame 10.
  • a pair of plugs 86, 88 are secured to the housing interior adjacent its respective ends and have a concentric tube 90 extending therebetween.
  • tubes 91 there are cavities in which pulleys 92, 94 are rotatably mounted and so positioned a that the enclosed reach of an endless cable 96 is coaxial with tube 90.
  • a piston 98 Attached to that reach of cable 96, there is a piston 98 which is driven back and forth in tube 90 by the admission of air through either of conduits 76, 1%.
  • tube 90 On its exterior, tube 90 carries a sleeve 1%2 which is secured to the outer reach of cable 96 and to which is secured the deflector bar 66.
  • Frame 56 includes a pair of arms 104, 106 and a pair of rods 1418, 110 (FIG. 6).
  • Arms 104, 1% are fixed to and extend radially from housing 58 as cantilevers. Their outer ends curve upwardly so as to extend a short distance around the empty driven chuck (FIG. 3) and are interconnected by smooth rod 110.
  • Arm 1114 also carries a small fixed triangular plate 112, the right-hand edge of which cooperates with rod 110 as a yarn guide during the transfer cycle.
  • Rod 163 also interconnects arms 1&4, 1%. As best shown in FIG. 3, it receives a bearing lock 114 which is secured to :bar 69 outwardly from the point at which the bar extends through a slot 116 in housing ss (FIG. 7) to its point of attachment with sleeve 102 (FIG. 6). At its outer end, deflector bar on is formed to present a guide hook 118 which is in alignment with the edges 80 on plates 72 of holder 62 and with the roove 52 (FIG. 2) on the driven chuck when in the transfer position of FIGS. 6 and 7.
  • FIG. 8 The condition of various related control components while a package is being wound on chuck 20 has been shown schematically in FIG. 8. Completion of the package is determined by a timer 12%? which. closes a switch 122 to connect solenoids 124, 126 and 12% to power source 121. With the energization of solenoid 124, a coupled valve plug 139 is rotated to admit air under pressure to assemblies 38, 41, thereby withdrawing brake shoe 40 and releasing arm 12 from its ready position. Energization of solenoid 123a pulls the spring biased actuator on coupled valve plug 132 to the left, thereby delivering air through conduit 14W to insure the initial location of deflector bar 64) adjacent the right end of slot 116 (FIG. 7).
  • solenoid 126 rotates a coupled valve plug 134 to its second position in which the lower end of cylinder 32 is exhausted to atmosphere. Resulting movement of the associated linkages causes clockwise rotation of pawl 34, permitting descent of arm 14. In its movement, pawl 34 also reverses the position of switch 136, thereby de-energizing solenoid 126 and energizing a solenoid 133. De-energization of solenoid 125 permits the clockwise return of valve plug 134. With both ends of cylinder 32 again pressurized, the piston therein returns relatively slowly to its initial position. Responsive to the action of a spring, pawl 34 also returns to its initial position where it can block descent of arm 12.
  • solenoid 138 momentary energization of solenoid 138 has opened switch 149 which then closes against the action of an attached dashpot, thereby insuring that solenoid 126 will not be energized a second time during the dofiing cycle.
  • the yarn would be deflected from package 28 to the rotating chuck and would not then be advanced at a rate suflicient to insure effective snaring and severing.
  • the yarn passes under tooth 76 on latch 74 until there is suflicient tension to pivot the latch against the bias of magnet 82.
  • yarn 2-6 rides free of edges 89 on holder 62 and moves laterally in a transfer tail of one or more helical wraps to a package area defined by the stroke of traverse guide 24.
  • yarn 26 is under positive control during the automatic transfer from package 28 to an empty package support 44.
  • a dashpot attached to the arm of switch 144 prevents its return to the position shown in FIG. 8 until the yarn has been transferred and is advancing directly to a support tube 44 on the driven chuck. Then solenoid 128a is reenergized to direct air once again to tube 90 through conduit 1%. In this manner, deflector bar 60 is returned to its ready position, i.e., to the right end of slot 116 (PEG. 7). Simultaneously, the cylinder of assembly 64 is vented to the atmosphere through conduit 66, permitting frame 56 of transfer mechanism 30 to swing gravitationally back to the position shown in FIG. 1.
