Definitions

  • This invention relates to yarn-winding machinery and particularly to pirn-winding machinery, and is especially concerned with an automatic pirn-winding machine of the kind described in U. S. Patent No. 2,306,268 of December 22, 1942, in which, when a pirn has been completed, it is automatically removed from the winding position and replaced by an empty pirn tube on which the winding of the fresh pirn proceeds.
  • the machine described in U. S. Patent No. 2,306,268 of December 22, 1942 is a spindleless machine, in which the pirn tube instead of being mounted on a long spindle passing through its axis, is gripped between two centres engaging with the ends of the tube, one of said centres being driven so as to rotate the tube.
  • the other centre is moved axially so as to release the completed pirn and allow it to drop away from the winding position and, before the centre so moved is returned, a fresh pirn tube is lifted by means of a pair of swinging arms into a position in alignment with the centres so as to be gripped on the return of the moving centre.
  • This machine is adapted for the winding of pirns on pirn tubes of a particular length, but it has now been found that the machine can be modified so as to wind pirns of any length within a substantial range.
  • the machine can be adapted to wind pirns of any length within a substantial range, and to accommodate the pirn tubes on which such pirns are to be Wound.
  • a convenient arrangement for lifting a fresh pirn tube into alignment with the centres comprises a horizontal shaft (i. e. parallel to the axis of the pirn being Wound) carrying a pair of depending levers, the lower ends or feet of which are adapted to engage the lowest pirn tube in amagazine containing a series of such tubes 5 Claims. (Cl. 242-32) 2, one above the other.
  • the feet are shaped so as to lift the lowest pirntube out of the magazine and into alignment with the centres and, when the tube has been gripped by the centres, to withdraw and leave the pirn tube in the winding position.
  • One of the lifter arms engages an empty pirn tube near the base thereof, and this arm is fixed on the horizontal shaft by which the arms are actuated.
  • the outer arm is arranged so that it can be adjusted along the length of the shaft, to correspond in position with the outer centre when the latter is adjusted in order to adapt the machine for the winding of a different length of pirn.
  • the actuation of the shaft is conveniently effected at a position thereon between the two arms and out of range of the movement of the outer or adjustable arm.
  • the traversing and chasing mechanism of the machine should be such as to give a potential traverse, i. e. the steadt movement along substantially the whole length of the pirn, over a distance suflicient for the building of the longest pirn in the range to be handled, the outer end of such potential traverse distance being unused when pirns of less than the maximum length are wound. It is also necessary, in order to Wind pirns of dilferent lengths, that the period of winding at the end of which the pirn is released and a fresh pirn tube supplied, should be adjustable. however, is normally provided in pirn-winding machines, whether automaticor not, in order to adapt them for the winding of yarns of different thicknesses.
  • the adjustment of the outer centre may be effected by any convenient means conforming with the means employed for moving the centre in order to release a completed pirn. It ispreferable that the latter movement should be efiect-' ed by mounting the centre on the end of a pivoted arm lying generally at right angles to the axis Such adjustment,
  • the position of the inner centre may be adjusted by adjusting the pivot of the lever which carries it, the lever being connected to its actuating means by a chain or link that is replaceable by one of difierent length when the length of pirn is to be changed.
  • the plunger may be carried on a vertical pillar, the base of which is secured in a slide along which it can be adjusted.
  • the former means are generally preferable as economising in, space-at. the front of the machine and enabling the maximum lengthof pirn to be increased Without increasing the space occupied by the machine.

  • spindle type of machine-the spindle emergesfrom the box i atYZ and is of sufficient length to penetrate through the pirn tube.
  • the spindle is cut oil and is represented only by a blunt point or driving centre 3 emerging from a collar 4, which is faced with rubber to provide a driving connection with the base of a pirn tube.
  • the other end or tip of the pirn tube enters, and is supported by a rotary cup 5 mounted in an outer.
  • bearing Parallelmtoithe position .of the pirn-tube between the centre 3 and the cup 5 is a traverse bar 1 operated from within the box I to execute a short to and fro traverse motion along the length of the pirn to be wound.
  • the side of the bar 1 adjacent to the pirnposition is threaded, as shown at S in-Fig z the other; half of the bar being plain asshown;,at;9 in;Pig. 2.
  • a feeler disc [0 is carriedonthe bar, the bore of the boss H of the discrzbeing.screw-threaded to correspond with the threads 18" but being enlarged so that the boss and-disc can be pressed to one side (towards the pirn) so as to be freed from the threads 8.
  • the plate I 9 carries not only; the camshaft lfiand the various cams mounted thereon; but also .the mechanism operated by said camsfoiy replacing the completed pirn by; an empty, pirn. tube and restarting the windingoperation.
  • the cam shaft 16 ismounted in horizontally slotted bearings in which it isretained.by.removable blocks 20 (Figs. 1 and 7), the -,-various levers; co-operating with the cams on the-shaft-beingso arranged that the shaft can be read-i-lyg'removed-without disturbing the levers.-
  • Beneath the cam shaft iG-and at right angles thereto is a driving shaft 2
  • the clutch is of the type described in U. S. Patent No. 2,176,970 of October 24, 1939, and is shown in the engaged and disengaged positions respectively in Figs. 4 and 5.
  • the clutch is en gaged by the motion of the starter handle I5, the free end of which is turned downward through a right angle as shown in Fig. 2 and is connected by means of an adjustable link 24 to a lever 25 (Figs. 3 and 6) mounted beneath the bracket I9.
  • the other end of the lever 25 carries a pin 26 (Fig. 6) engaging beneath a lever 21 secured to a shaft 28 carried in bearings beneath the edge of the plate IS.
  • the shaft 26 carries a further lever 29 by means of which the cam-shaft clutch is normally held out of engagement.
  • the starting handle I and link 24 rise so that the pin 26 and lever 21 fall and the free end of the lever 29 moves away from the cam shaft I6.
  • the clutch as shown in Figs. 4 and 5, comprises a disc 36 secured to the worm gear 23 and provided with four semi-circular notches equally spaced around its periphery. Close to the disc 36 is a disc 32 secured to the cam shaft I6, the disc 32 having pivoted to the face thereof adjacent to the disc 36, a substantially tangential lever 33 and a substantially radial lever 34. The free end of the lever 33 projects sideways across the periphery of the disc 36 and is shaped to fit the notches 3 I. The lever 33 however is spring-loaded outwards so that the end of the lever tends to disengage from the periphery of the disc 36.
  • the lever 34 extends past the lever 33 and its free end is bent over so as to engage the outer side of the lever 33 which is shaped so that as the end of the lever 34 moves towards the end of the lever 33 it forces the lever 33 inwards against the periphery of the disc 36.
  • the lever 34 is loaded by means of a spring 35 strong enough to overcome the spring loading of the lever 33. During the winding of a pirn, however, the lever 29 engages the lever 34 and prevents it from forcing the lever 33 against the edge of the disc 36.
  • the first effect of the rotation of the shaft I6 is to permit the discharge of the completed pirn. This is done (Figs. 1, 2 and 6) by moving outwards the outer bearing 6 and the cup 5 by means of which the pirn is pressed against the spindle point 3.
  • the outer bearing 6 is carried on the upper end of a lever 31 which isv loaded inwards by means of a spring 38 (Fig.6) to enable the cup 5 to hold the pirn tube against the spindle point 3.
  • the lever 31 is connected by means of a chain 39 to the upper end of a lever 46 pivoted at II on the end plate I8 beneath the bracket I9.
  • the lever 46 carries a cam follower 42 engaged by a cam 43 on the cam shaft I6, by means of which the lever 46 and thereby also the lever 31 are withdrawn to release the complete pirn.
  • the lever 31 is pivoted at I06 in a slot IDI along which the pivot I60 may be adjusted by means of a nut I62.
  • the position of the outer bearing 6 can be adjusted to take pirns of any length allowed within the range of the length of the slot IOI.
  • the chain 39 is shortened or lengthened to suit the new position of the pivot I60.
  • a plate I03 (Figs. 2, 3 and 6), moving with the pivot I60, is provided to which the lower end of the spring 38 is fixed.
  • the cam 43 is a dual purpose cam, having a shaped projection 44 (Figs. 1, 6 and 9) on the face thereof for engaging the cam follower 42 and a projection 45 on the edge thereof (Fig. 6) for engaging a cam follower 46 carried by the lever 25 for a purpose to be described hereafter.
  • the completed pirn released by the retraction of the cup 5 in a manner described drops through a hole 41 in the plate I 9 and is received and guided away by means of a chute 48 (Fig. 1).
  • the lever 56 is swung counterclockwise as viewed in Figs. 1 and 8 by means of a cam 52 on the cam shaft I6.
