Definitions

  • Our present invention relates to twisting mechanisms for spinning, twisting and the like machines.
  • the present invention aims at providing a twisting mechanism, particularly a double torsion twisting mechanism having disconnection device controlled by a feeler, which is of simple construction and in which the feeler requires only a moderate load which is permissible even for fine threads.
  • the present invention consists in combining, with such a known twisting mechanism, particularly a double torsion twisting mechanism, the spindle of which is carried by a support adapted to pivot in a vertical plane and applied by the action of a weight or spring against a driving means, means for deriving the disconnecting movement from the reciprocating movement of the thread guide.
  • These means are constituted in the device according to the invention by two lifting bodies, cooperating with the aid of inclined sliding surfaces, and normally distant from one another, one of which performs a reciprocating movement toegther with the thread guide or arod driving the same, while the second body is disposed on the spindle support and is movable transversely relatively to the direction of movement of the thread guide, in such manner as to be brought, in the event of the breakage of the thread, by the feeler, likewise mounted on the support arm, into the path of the lifting body performing a reciprocating movement.
  • the rocking support of the spindle is rocked, by the wedge acz tion of the lifting cams, out of its working position and lifts the spindle from its driving means.
  • Fig. 1 is an elevation, partly in section, of a double torsion twisting frame in the working position
  • Fig. 2 is a similar view showing the stopped position
  • Fig. 3 is a similar view showing the start of the disconnection operation at the time of the breakage of the thread
  • Fig. 4 is a similar view showing the disconnection of the drive
  • Fig. 5 is a front view of two lifting bodies
  • Fig. 6 is an elevation, partly in section, of a modified detail.
  • l designates the basic body, having the form of a rod of a spindle support which is suspended at 2 in such manner as to be pivotable in a vertical plane, said support carrying, on a leftwardly extending lower arm 3, as viewed in Fig. 1, the double torsion twisting spindle 4.
  • An upper arm 5, located over arm 3, on the support includes guide means constituted by an eye 8 and a roller 1 for the twisted thread running from the spindle 4 towards the winding bobbin 8.
  • the spindle support I, 8, 5 is rockable between two end positions determined by stops 9.
  • a driving means In constituted, for example, by a per se known endless belt.
  • the wharve is removed from the belt, so that the drive of the spindle is disengaged.
  • Application against the drivingmeans is effected by the dead weight of the spindle and the support.
  • an energy storage means of the socalled dead centre type is provided, which acts on the spindle support alternately in one direction or the other.
  • This storage means is constituted by a leg inserted between the bottom end of the rod forming the basic support body and a fixed point, this leg being essentially constituted by a helicoidal compression spring II in such manner as to be able to be compressed elastically.
  • the spring is mounted by spherical shoulders I2 on each end, engaging in socketshaped depressions in the rod I and an arm I3 fixed to the frame of the machine, respectively.
  • the leg is disposed in such manner as to be inclined upwardly to the right, as viewed in Fig. 1, in the position corresponding to the engagement of the spindle drive, and to be inclined upwardly to the left, as viewed in Fig. 1, in the position of disengagement.
  • spindle support I, 3 is rocked about pivot 2
  • the leg passes through its dead centre position, which has the effect that, as soon as the support passes the middle position and the leg passes its dead centre position in relation to the support, the leg applies pressure to the spindle support towards the end positions corresponding to the direction of movement of the support.
  • the winding bobbin 8 and its drive comprising a hollow driving roller I4 and a friction roller I5 cooperating with the internal surface of said driving roller, are disposed above the upper arm 5 of the spindle support.
  • the support arm 5, beneath the driving roller I4, carries a support I5 having substantially the form of a trough, which, at the time of the rocking of the spindle support in the disengagement direction, lifts the driving roller from the friction roller I5, so that the drive to the winding roller is disengaged simultaneously with the disengagement of the twisting spindle.
  • the reciprocating thread guide II having a slide I8, which moves the twisted thread running onto the winding bobbin to and fro in the direction of the axis of the latter.
  • a lever I9 pivotable in a vertical plane, is mounted on the lower side of the slide I8 of the thread guide, said lever being held by a strong spring 20 in the almost horizontal position of rest, illustrated in Fig. 1.
  • the lever I9 carries a lifting body 2I comprising at its upper part two inclined faces in the form of a chevron (see Fig. 5). The lifting body 2
  • is adapted to cooperate with a port arm 5.
  • the lever 23, which is upwardly directed, has an angle formed therein and is pivotallymounted adjacent to the vertex of the positions determined by the opposite edges of a stop member 31, as is clearly evident from Figs. 1 and 3.
  • Its position is determined by a small weight 24 which is disposed in such manner that the centre of gravity of the lever is situated on one side of the vertical plane of the pivoting axis 25 of the lever in one end position and on the opposite side of said plane in the other end position.
  • the weight 24 maintains the lever in the selected end position, while promoting or completing, on rocking of the lever, the movement of the latter towards the other end position, as soon as the lever has passed its middle position.
  • the lever 23, mounted on the support arm 5, is normally located in the position shown in Fig. 1, in which the second lifting body 22 is located away from the first lifting body 2
  • the second lifting body 22 comes in contact with the first lifting body 2I, which, due to the cooperation of the inclined surfaces of the two lifting bodies, applies on the spindle support I, 3, 5 a torque in the direction of the movement of disengagement.
  • a feeler constituted by a light lever 26 which is applied, under the action of a small weight 28 adjustably mounted on a counter-arm 21 on the feeler lever, from below against the twisted thread running from the guide roller I towards the winding bobbin 8.
  • the feeler 26 serves to bring the lifting body 22 into the path of the oscillating lifting body 2
  • the feeler lever drives, at the time of the breakage of the thread, the lever 23 because the hub part 29 of feeler 26 strikes against and moves, after some dead travel, a small driving arm 30 on the lever 23.
  • The'dead travel between the feeler and the lever carrying the lifting body 22 is selected in such manner that the thread guide can follow the twisted thread without driving the lever 23 and the lifting body 22, when the thread has a little slack on stoppage of the machine (see the position shown in Fig. 2).
  • the hub part 29 of the feeler lever 26 has also a finger 38, which is intended to cooperate with a stop surface formed on the lever 23, for example by the weight 24, in order to return, at the time of the return of the feeler lever to its initial position, the lever 23 carrying the lifting body 22 to the position shown in Figs. 1 and 2, if this lever should have rocked into the position shown in Figs. 3 and 4 as the result of a breakage of the thread.
  • the dead centre energy storage means constituted by the leg ll passes through its dead centre, which has the eflect that it applies, when the spindle support has passed the middle position, a pressure on said [support directed towards the position of disengagement, in such manner as to complete with certainty the movement of said support.
  • the spindle support may be advanced slightly beyond the position determined by the inclined surfaces of the lifting bodies 2
  • the broken thread is joined, it is replaced in its guide on the feeler lever 28, which thus returns to its initial position as shown in Fig. 1, and in turn, through the medium of the finger 38, likewise returns the lever 23 carrying the lifting body 22 to its initial position shown in Fig. 1.
  • the twisting frame is re-started by rocking the support I, 3, 5 by hand into the position of engagement.
  • may be provided on the lower arm 3 of the support.
  • the elastic leg ll acts, after passing its dead centre position, in the direction of a continuation of the movement of the support towards the position of engagement, and likewise reliably completes that movement.
  • the spindle support is held in the two end positions by the elastic leg.
  • the elastic leg ll may be replaced by a weighted energy storage means.
  • a lever 33 which is directed upwards is rotatably mounted around a fixed point 32, said lever being articulated by a slot 34 and a pin 35 on the rod i of the spindle support, while it carries at its upper part an adjustable weight 36.
  • the weighted lever arranged in this manner likewise passes through a dead centre position, at the time of the rocking of the support, in such manner as to have the same eifect as the elastic leg illustrated in Figs. 1 to 4.
