Definitions

  • PATENTEU FEB 2 ISYI SHEET 1' OF G INVENTORS
  • This invention relates. in general. to high speed winding machines and. in particular. to an automatic threading system or arrangement for such machines.
  • the filaments are in somewhat softened condition during the period of passage around the Godet rolls, and it has been found that unless the linear speed of the yarn and the peripheral speed of the core at the moment of attachment correspond to a very close degree, i.e., within a few percentage points, the results are not acceptable. If the core speed is higher, the yarn will be excessively stretched. If the core speed is lower, a slight hesitancy in the flow of the yarn will be produced which permits the yarn to stick to a Godet roll and wrap therearound. This precision of correspondence is not practical depending upon centrifugal force.
  • the basic object of the invention is a mechanical arrange ment for automatically threading a moving strand onto the rotating package core of a high speed strand winding machine without retarding the rate of movement of either strand or core and without bread breaking or undesirable stretching the strand.
  • a further object of the invention is a mechanism for delivering an advancing strand to a rotating spindle and core under precise control and in definite stages in order to insure as much as possible effective engagement of the strand upon the spindle combined with positive displacement of the strand onto the core.
  • Other features include means carried on the spindle at the locus of initial contact thereof with the moving strand to reduce the frictional effects of such contact upon the strand as well as a structural modification .in the end edge of the package core to facilitate the transition of the winding strand from the spindle periphery to the core periphery.
  • An aspirator nozzle receiving an advancing strand of yarn, as from the Godet wheels of a continuous filament extrusion system is supported, in a detachable manner if desired, to facilitate initial delivery of the advancing strand to the nozzle to a threading position wrapping the strand around an arc of about 60 or so of the periphery of an exposed end of a takeup spindle.
  • the nozzle is mounted on and movable by a rigid arm mounted upon a part of the frame of the winding machine for pivotal movement. Thus, the nozzle is movable from a loading position spaced above the takeup spindle to said threading position.
  • a strand severing device may also be supported by the pivotal arm in a position suitable for cutting the strand at the proper time.
  • the strand initially contacts the spindle at one extreme end which is preferably formed to reduce the frictional effects of such contact upon the flow of the strand, e.g., provided with flats to vibrate the strand.
  • the arm and nozzle are displaced axially of the spindle to align the nozzle end with a chordal notch in the spindle periphery intermediate the extreme end thereof and the core end edge, a downwardly directed hook being disposed in the notch.
  • the strand is held against a corresponding movement away from the flatted spindle end by the edge of a detent plate projecting into the strand path adjacent the guide slot until the displacement of the nozzle is complete.
  • the detent plate is withdrawn laterally from the strand path at a controlled rate permitting the strand to shift laterally into engagement with the edge of a step on the detent plate.
  • the step edge is in transverse alignment with the notch containing the hook and thus delivers the strand into the notch for engagement with the hook so that as the strand begins to wind upon the spindle, the strand is thereby displaced from its threading path into the cutter which serves the strand between the hook and aspirator. Further withdrawal of the detent plate frees the strand from the step for delivery upon the core which is slidable received upon the spindle.
  • a notch is preferable provided in the end edge of the core to facilitate movement of the winding strand from the spindle periphery to the larger core periphery.
  • FIG I is a somewhat diagrammatic perspective view of a high speed winding machine equipped with the automatic threading mechanism of the invention.
  • FIGS. 2'6 are detailed perspective views illustrating the essential components of the invention in their relative positions step by step through the threading operation. such components being shown in somewhat idealized fashion and generally detached from the remainder of the machine with only enough supporting structure being shown as to convey the relationship of such parts to the remainder of the machine;
  • FIG. 7 is a detail view in front elevation of the aspirator mountingbracket
  • FIG. 8 is a detail view in end elevation of the mounting bracket of FIG. 7;
  • FIG. 9 is a detail diagrammatic view of the pneumatic and electrical control circuit for positioning the strand detect plate.
  • FIG. 10 is a view similar to FIG. 5. showing a modification of the invention for winding packages including an end bunch DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS
  • the winding machine with which the present improvements are associated includes a main housing 12 which contains the drive motor, transmission. and motor speed control, all not shown.
  • the speed control is responsive to variations in the tension in the strand as determined by a strand tension sensing arm 14 having at one end a guide 16 engaging the strand and affixed at the other end to a shaft 18 transmitting to the motor speed control the pivoted motion of arm 14 incidental to tension variations in the strand.
  • the guide 16 is of the type described and claimed in us. Pat.
  • the motor speed control includes a starting position for driving the spindle at a fixed predetermined rate, which is preferably adjustable between limits, until a control indication signals the completion of the threading phase and releases the control to the influence of the tension sensing arm.
  • Speed controls of this type are known in the art, as for ex' ample in the aforementioned US Pat. 2,481,031.
  • the predetermined starting position can be'determined mechanically, i.e., by mechanical engagement of the tension sensing arm in a fixed position, as shown in US. Pat. 2,48l,03l or, more preferably, through the electrical circuitry of the system.
  • the spindle 20 Extending in generally cantilevered fashion from the upper portion of housing 12 is the spindle 20 which is adapted to support a package core 22, the core being placed on the spindle and removed therefrom via the unsupported spindle end.
  • a strand traverse housing 24 Rearwardly of and generally parallel to the periphery of spindle 20 is a strand traverse housing 24 which includes the strand traverse guide means (not visible) for delivering the strand to and from along the length of package core 22 to build a package thereon and an idler roll 26 frictionally coritacting the package periphery, only one end of which appears in FIG. 1.
  • a strand feed slot 25 (better seen in FIG. 2) which maintains the strand under loose control while it is being traversed and delivered to the winding spindle.
  • the feed slot 25 holds the strand adjacent the traverse mechanism so that it does not fly out of control. Entrance in slot 25 is had through its open outboard end, as at 27, and a latch finger (not visible) may be projected into the open end once the strand has entered the slot to prevent the strand from escaping during operation.
  • a mounting bracket for the support arm 32 holding a strand aspirator 34
  • the mounting bracket 30 includes a base plate 36. bolted or otherwise firmly attached to the housing top wall, from which upstand at least two spaced bearing blocks 38, 40.
  • Bearings 42, 44 are arranged in the blocks 38, 40 in which is journaled for both rotary and axial reciprocating movement a pivot shaft 46.
  • An end wall 48 may be provided on the forward or outboard end of the bracket for purposes of protection or to support any desired control devices.
  • shaft 46 is encircled by a hub or boss 50 formed integrally with the support arm 32 at one end thereof and which tightly fits around the shaft for unitary movement therewith.
  • the support arm 32 is adapted for pivotal movement to and from two positions: an inoperative or loading" position and an operative or threading position.
  • a follower roller 52 is arranged to pivot with the support aim, being rotatable fixed to the end of a pin 54 extending in a generally radial direction through the hub 50 and shaft 46.
  • Two opposed stop blocks 56 and 58 cooperate with follower roller 52 to determine thelimits' of travel of the roller and hence of'the support arm.
  • Stop block 56 is firmly secured to the base plate 36 of the bracket generally beneath the hub 50 and serves to define the loading position. It is formed with a stepped'front face 60, the roller rolling upon the step face 60a until prevented by the end face 60b at which point the support arm is in its inoperative position The extent to which the vertical end face 60b is offset from a vertical plane passing through the axis of shaft 46 in relation to the diameter of the follower roller 52 will determinethe angular location of arm in its inoperative position and stop block 56 may be constructed for adjustment transversely of the base plate. i
  • stop block 58 is bolted to the rear edge of the base plate in generally transverse alignment with hub 59, projecting upwardly to endin an inclined leg 62, the inner face 64 of which engages the roller 52 and is therefore inclined at an angle selected to match the radial position of the roller periphery at the desired threading position.
  • Stop block 56 is contoured at its end adjacent stop block 58' in such a way as to release the roller from contact therewith just before the roller makes contact with the stop face 64 of leg 62, as by the removal of its upper rear corner at 66.
  • the purpose of such contouring is to' create sufficient clearance as at 68, between the adjacent surface of the stop block to accommodate the follower roller 52 therebetween for a purpose to be described shortly.
  • the support arm may be equipped with an overcenter spring means, not shown in detail, to bias the arm to one or the other of its two extreme positions.
  • support arm 32 is adapted to carry means for receiving the running strand, which preferably takes the form of an aspirator nozzle 34, in a fixed position relative to the arm.
  • a stud 70 projects outwardly of a boss 72, at the free end of the arm in parallel relation to the cylinder axis, carrying at its remote end a transversely extending socket plate 74.
  • Plate 74 is formedwith an aperture 76 serving as a socket to receive and retain the aspirator nozzle in generally spaced parallel relation to the axes of stud 70 and of the winding spindle 20.
  • Latching means such as a spring-pressed ball detent, not shown, may be included on the socket plate for positive engagement with the nozzle, if desired.
  • aspirator nozzle 34 is not a critical aspect of the invention and any design may be adopted proided only that it provides the strong degree of tension necessary to handle the advancing strand
  • One embodiment found useful is that described in the copcnding application of Henry A. Vandersip. Ser No. 797.203 filed Feb 6, l969.
  • Compressed air is supplied to the intake pipe 78 of the nozzle through a supply air hose 80 while the exhaust from,the noz zle. including the strand when present, is delivered away through a discharge hose 82.
  • the hose 82 may empty into a screened receptacle to simplify collection and removal of the strand accumulated during the prethreading period.
  • support arm 32 is in its up" or loading'- position. remote from the spindle periphery.
  • the aspirator nozzle 34 in its mounting plate 74 being supported by stud 70 generally above the outboard end of strand traverse housing 24.
  • the running strand. indicated at S is directed into the strand feed slot 25 adjacent the forward face of the housing 24 through its open end 27
  • the axis of nozzle 34 is in approximate longitudinal vertical alignment with the slot 25 with the nozzle end being in transverse vertical alignment with the exposed end of spindle 20.
  • aspirator nozzle 34 is moved to its threading position by rocking support arm 32 in a clockwise direction viewing FIG. 1.
  • spindle is being driven at the fixed predetermined rate established by the motor speed control starting position and in the direction of arrow on the spindle 20 in FIG. 1.
  • this rate is slightly in excess of the normal output rate of the Godet delivery rolls of the extrusion or other strand supply system.
  • the spindle speed should be preset to rotate the periphery of core 22 about 50l00 ftJmin. in excess of that rate.
  • the threading position for nozzle 34 is shown in FIG.
  • the nozzle is situated generally on the opposite side of the spindle centerline from traverse housing 24 a sufficient distance radially outwardly from the spindle axis as to be well clear of the spindle periphery.
  • the moving strand S makes contact with an arc of about 60- 90 or so of the periphery of the exposed end of spindle 20.
  • the preferred friction-reducing measure is the provision of an extension 90 on the free or outboard end of the spindle which is formed with flats 92 on its peripheral surface.
  • the effect of the flats 92 is to impart vibration to the moving strand S and thereby reduces its friction with the spindle surface.
  • the number of the flats may be varied as desired.
  • Positive control over the lateral displacement of strand S during threading is essential and in accordance with the invention. such control is accomplished by means of the strand detent plate 100.
  • This plate at the starting of threading is interposed across the transverse path of strand S within the feed slot 25, being preferably mounted adjacent the lower wall of the traverse housing 24 so as to act upon the strand while under the general control of feed slot 25.
  • Detent plate 100 is constructed with at least two control or detent edges constituted by leading end edge 102 and the edge 104 of at least one forwardly projecting step 106.
  • a short distance inboard of flatted extension 90 but still on e the exposed end portion of the spindle is a generally V- shaped chordally extending notch 107 at the midpoint of which is disposed a downwardly opening hook of finger 108.
  • Hook 108 projects over the transverse centerline of notch 107 so that strand S is guided by the notch wall beneath the hook and will thereby be caught bythe hook and caused to wind upon the spindle end.
  • the function of the second detent edge 104 on detent plate 100 is to deliver strand S into registration with the notch 107 -and hook 108.
  • shaft 46 is adapted to slide axially in its bearings 42, 44. Consequently, shaft 46 can be biased for bodily axial movement along with support arm 32 and nozzle 34, the biasing becoming effective as soon as the arm is swung to threading position.
  • a pneumatic cylinder can be employed to apply the bias at a controlled rate until the shaft reaches its axial end position with the nozzle end displaced at least as far as the notch 107.
  • the cylinder is, of course, tensioned when the arm 32 is returned to its initial position, said arm 32 being freed for pivotal movement only after shaft 46 has been displaced axially to bring roller 52 clear of step face 60 on stop block 56.
  • nozzle 34 does not bring about a corresponding movement of the strand until the strand is released from engagement with the leading edge 102 of detent plate 100, such release being effected by withdrawing plate 100 from the strand path to the extent necessary to permit the strand to pass on to the stop 106.
  • This withdrawal should not occur until nozzle 34 is in its axially displaced position and the arrival of the shaft 46 at the limit of its axial travel may advantageously be used to signal the withdrawal of plate 100 by closing a switch or valve to actuate a solenoid or air cylinder acting to position the detent plate.
  • notch I10 is for its downstream wall to extend perpendicularly of the end face of the core with its upstream wall inclined to the core face and intersecting with the downstream wall a short distance. say about z-inch. inside the core In this way.
  • the shifting strand S encounters a substantially perpendicular edge in transferring to the core and will be more likely to catch on and ride over that edge than over the end shoulder of the core 22 in view of the relatively small inclination of its lead angle relative to the plane of the shoulder which tends to cause the strand to be sloughed off onto the exposed cylinder periphery.
  • This cutting device is supported in a position adjacent the spindle periphery below and generally between the nozzle opening and the point of tangency with the spindle periphery of a line drawn through the nozzle opening. Specifically. the location of the cutter must be such that as the strand caught by hook 108 begins to wrap around the spindle periphery, say, after a total of about 120 of wrap around, it is drawn into the V of the blades under sufficient tension to be cut thereby.
  • cutter 114 can be mounted on a fixed support of its own if desired, extending from any convenient part of the machine.
  • cutter 114 is integrated into structure of the invention as appears in FIG. I.
  • the cutter can be carried on a link I16 pivoted on the boss 72 at the end of support arm 32.
  • the operative position for the cutter may be found to interfere with the path of the strand to the aspirator nozzle when in in operative or loading position. In this event, the cutter can be manually pivoted to an out of the way position during loading and then swung back to operative position when the nozzle is moved to threading position.
  • a stabilizing rod 1 I8 can be connected at its ends to the link I16 and to a fixed part of the mounting bracket, for instance, the inboard bearing block, the pivot axes of rod 118 being so arranged that movement of support arm 32 to loading position automatically swings the cutter 114 counterclockwise out of the path of strand S running in loading position to the nozzle opening and, conversely, movement of the support arm to threading position locates the cutter in effective working position.
  • the mechanism of the invention is readily susceptible to manual positioning of support arm 32 between its loading and threading positions.
  • Aspirator nozzle 34 is ordinarily manipulated by hand during loading in any event and the operator is hence already conveniently nearby to perform this basic maneuver after which the mechanism performs the remainder of the necessary operations automatically.
  • power actuation of support arm 32 is easily possible and one form of power actuation has been included in the design of mounting bracket illustrated in FIGS. 7 and 8.
  • a tubular extension 120 is provided for the shaft 46 with a limited telescoping connection therebetween, as at 122.
  • the telescoping section of extension 120 is formed with a curved slot 124 which is engaged by a pin I26 rigidly projecting radially from the telescoping section of shaft 46, the curvature of slot 124 being such that axial movement of the extension imparts the desired arc of pivotal movement to the pin 126 and thence to shaft 46 and support arm 32.
  • the extension is held against rotation by a slideway 128 and is connected at its inboard end to the piston of a compressed air power cylinder I30 clamped to the inboard end of base plate 36v Compressed air is supplied to the cylinder I30 under the control of a pushbutton valve I32 which can be mounted in an accessible position on end wall 48 Admission of the air drives the piston to the right in FIG. 7. lowering the support arm to its threading position.
  • the piston is spring-loaded to return to the left when the air flow is halted, the movement being at a gradual rate determined bya conventional adjustable vent in the cylinder wall.
  • the functions just described can also be accomplished manually.
  • a pushbutton switch 134 can be disposed on a fixed standard at the piston end of the power cylinder 130, the switch being contacted by a probe 136 moving with the shaft extension. It is desirable for the probe to be threaded for axial adjustment to permit precise timing of the closure of' switch 134.
  • the control circuit for positioning detent plate is quite simple and is illustrated somewhat schematically in FIG. 9.
  • Plate 100 is supported for sliding movement in the spaced guideways 140 secured, for example, to the underside of the traverse housing 24.
  • a drive rod 142 extends rearwardly of the plate through the bore of a solenoid 144, the core 146 of the solenoid encircling the rod for movement therewith, connecting at its remote end with the piston of an air or hydraulic cylinder 148 clamped tothe housing underside.
  • Solenoid 144 is controlled by switch 134 and as the switch is closed by the arrival of the shaft 46 to its limit position, solenoid 144 is actuated to move plate 100 rearwardly out of the path of strand S, the rate of withdrawal being determined by the cylinder 148.
  • the air cylinder piston is braced to move to the right when released and return of the shaft 46 and support arm 32 to loading position results likewise in the return of plate 100 to its effective detent position.
  • control instrumentalities could, of course, be substituted and the functions of the solenoid and air cylinder could be combined in a single air cylinder controlled by a valve at 134.
  • switch 147 Arranged near the plate 100 is a switch 147 having a contact arm, I49 extending toward the rear of the plate. The end of arm 149 is situated so as to be depressed by the plate when the latter reaches its fully withdrawn, i.e., inoperative,'position indicated in solid lines in FIG. 9.
  • Switch I47 is connected to the motor speed control circuit and is operative when actuated to disengage the fixed speed starting portion of that circuit and institute randomly variable speed control in response to tension variations in the strand.
  • a package will be desired having a transfer tail, i.e., a small group of strand coils on the core in an axially separated position from the main package for use in uniting with the strand on a subsequent package or for automatic engagement with the free strand end.
  • a transfer tail i.e., a small group of strand coils on the core in an axially separated position from the main package for use in uniting with the strand on a subsequent package or for automatic engagement with the free strand end.
  • Such a package can be easily produced by the invention through a single modification of the detent plate as shown in FIG. 10.
  • the modified plate 150 is formed 'with twosteps I52 and 154 to give atotal of three detent edges I56, 158, instead of two as in the main embodiment. Edges 156 and 158 correspond to edges I02 and 104 in plate 100 and have the same function.
  • Edge 160 on the additional step 154 is spaced axially of the bedding edge 156 a sufficient distance to coincide with the end portion of the core 22 inside of notch 110. After the strand has slipped past edge I58 and migrates onto the core. it is held by edge 160 at a locus spaced axially outwardly of the normal limits of travel of the strand traverse guide and is caused to wind into coils at that locus as at 162. The number of coils in the bunch 162 is determined by the length of time the strand is held by the edge 160 which is, of course. a function of the rate of continued withdrawal of the plate.
