Definitions

  • the filaments are drawn at a uniform linear speed and are generally wound on cuffs supported by cylindrical mandrels, called pins, using a distribution device.
  • the filaments leaving the die are grouped either in a single thread wound on a single cuff, or in several threads wound simultaneously on separate cuffs placed end to end on the same spindle. For productivity reasons, it is particularly important to ensure the continuity of this operation.
  • a first spindle when the desired quantity of wire has been wound by a first spindle, the latter deviates from its working position, while continuing to draw the wires; a second empty spindle, already in rotation, then takes the place of the first, collects the wires still being drawn and continues their winding.
  • the wires can be collected directly and separately by each cuff. More usually, on the barrel winders, we collect, in a specialized area of the empty spindle placed at the end of the latter, the threads that have been temporarily grouped during drawing and then we bring each thread on his own cuff in order to start new windings.
  • a simple method consists in ensuring the transfer by a rapid deceleration of the full spindle gaining the rest position while the empty spindle gaining the working position rotates at the normal winding speed of the wire. Due to the increasing gap between the two speeds, the adhesion drive of the wire on the empty spindle eventually prevails over the traction exerted by the full spindle; a loop is then formed between the two pins, immediately trapped by the wire driven by adhesion on the empty pin and initiating the winding on the latter. It is apparently a process of this type that US Pat. No. 3,409,238 calls for.
  • a knife is inserted very quickly between the two pins during their permutation so as to slice the wire; the rear strand, separated from the full spindle, but driven by its adhesion to the empty spindle, is trapped under the strand from the dies, so that the drawing is taken up by the latter.
  • the end of the spindle is, for example, fitted with a circular plate. At the end of the ejection, each wire is wedged in the circumferential groove delimited by the plate and the end of the spindle as soon as the first turn is formed.
  • the present invention also relates to arrangements
  • the transfer is carried out in a conventional manner: as shown diagrammatically in FIG. 1B, due to the difference created between the speed of the wire F and the peripheral speed of the empty spindle B2 (either by using only the difference between the angular velocities w2 and w1, i.e. by further slowing down the pin 81), also due to the significant increase in the arc of contact between said wire and the pin 82, this action has the effect of causing instantly drive the wire F by adhesion to said spindle.
  • the quantity of wire drawn by spindle 82 becomes greater than the quantity of wire wound by 81. This is shown schematically by the displacement of point 8 at B 'taken at the start of the process, and the slight relaxation of the wire which results therefrom.
  • the recovery of the wire F by the pin 82 ends with the breaking of the wire by abrasion which occurs at point A.
  • the winding of the wire can then continue on the pin 82.
  • the method according to the invention can be implemented by devices such as those described below by way of nonlimiting examples.
  • the device shown in FIGS. 2 and 2A is adaptable to any current barrel winder, either winding a single thread and with which the latter is ejected on the edge of the cuff, or winding one or more threads and with which these are ejected all together on the end of the spindle.
  • FIG. 2 does not show the device for ejecting the eyelash (s) which will be discussed later.
  • the transfer device essentially comprises a jack 1, the rod of which is provided at its end with a V-shaped finger 2, the edges of which are not very tapered, and an external parallel guide rod 3 passing through a hole or eye. 4; fixed very rigidly by the strap 5 at the end of the rod of the jack itself, its purpose is to maintain the orientation of the finger 2 during the maneuver by preventing the rod of the jack from turning on itself.
  • the jack 1 can then be fixed on the ground or on the frame of the winding machine itself by an assembly method not shown. Its positioning is such that the finger 2 moves in the vertical plane in which the tensioned wire has been brought by an ejector such as those described below, with a view to its transfer, before rotation of the barrel B3.
  • the orientation of the cylinder rod is such that in its movement, the finger 2 meets the taut wire 6 between the two pins and drives it in a vertical plane slowly enough not to cut it.
  • the cylinder stroke is chosen as large as possible in order to obtain the largest possible winding arc.
  • the orientation of the jack will cause the rod to pass as close as possible to the empty spindle in the working position because it is on this spindle that one seeks to increase the initial winding arc ⁇ o.
  • the actuator control mode can be, for example, hydraulic or pneumatic.
  • the actuation command can be determined by a distributor 7 controlled automatically as soon as the barrel is indexed; this information can be taken from the winder control cabinet at the end of rotation contact.
  • the actuation control of the cylinder can be very advantageously performed simultaneously with locking, by the distributor 8 which controls the locking cylinder 9 of the barrel. 63; in this case, the cylinders 1 and 9 are connected in parallel to the distributor 8. The rod then remains in position "working" throughout the operation of bobina- g e.
  • the two pipes 10a and 10b for connecting the latter to the distributor will be provided with two quick couplings which can be snapped in order to be able to possibly remove the winder.
  • the device shown in Figure 4 derived from the previous one is adaptable to a barrel winder simultaneously winding two son which, for transfer, are simply moved out of the distribution device.
  • the previous finger 2 is simply replaced by the blade 13, consisting of a plate provided with two notches 14 and 15, which moves in a plane parallel to the axis of rotation of the pins.
  • the positioning of the jack is such that, when the blade 13 moves, the two notches 14 and 15 remain in the two vertical planes perpendicular to the axis of the spindle and passing through the middle of the windings and in which the wires 11 and 12 are naturally located after being removed from the field of action of the distribution devices 16 by displacement of a cylindrical bar 17 parallel to the axis of rotation of the pins, for their transfer.
  • FIG. 5 Another device, shown in Figure 5, is designed for a barrel winder on which, for transfer, the son are ejected all together on the end of the spindle.
  • This device is fixed to the frame of the winder. It comprises a horizontal shaft 21 which can rotate in two bearings 22 integral with the frame 23 of the winder. This shaft comes out parallel to the spindle 82 and loses a curved lever 24 at the end of which the finger 2 is fixed.
  • the shape and length of the curved lever 24 are determined so that it does not meet the pins in its movement, so that the winding arc obtained is as large as possible and so that the finger 2 can move in the plane containing the strand stretched between the two pins during the transfer operation and driving this strand in its movement.
  • the wire distribution device has been omitted for clarity.
  • this ejector consists of an arm 26 carrying a bar 27, the rotation of which separates the wire from the distribution device, and an ejector fork 28 sliding on a support 29, which brings the wire at the end of the shaft, facing the spindle nose, in the plane of the finger 2.
  • an ejector is described in more detail in the French patent published under number 2 291 138.
  • the finger 2 ending the end of the lever 24 is replaced by the blade 13 previously described.
  • the lever 24 is positioned so that the notches 14 and 15 move in the vertical planes in which the wires 11 and 12 have been brought for their transfer, that is to say after simple separation of the field of action of the 16 wire distribution devices, either after ejection from the winding.
  • FIG. 6 Another variant of the previous device, adapted to this particular case, is shown in FIG. 6.
  • the embodiment chosen comprises a horizontal shaft 33 fixed under the body of the distribution mechanism 30 parallel to the spindle.
  • the shaft carries at one of its ends the curved lever 24 and the finger 2 described above.
  • the other end of the shaft 33 carries a crank arm 34 keyed at a predetermined angle.
  • crank arm 34 is articulated at one end of a link 35, the other end of which rotates around a fixed journal 36 secured to the frame 23 of the winder.
  • the contact arc of the wire with the empty pin B2 is of the order of 130 ° on average. They allow the transfer, either of fine threads (titer less than or equal to 160 tex) whatever their sliding qualities on a smooth support, or of larger threads (titer between 160 and 1200 tex) little slippery, on a support smooth.
  • the bar feed element 41 is either a small blade 41a having a V-shaped edge 42a, or an elongated blade 41b, the edge of which is formed by two V 42b, depending on whether the transfer is to be carried out on the end of the spindle or directly on the cuffs.
  • One or the other of these two blades is fixed to the end of a cylindrical rod so that it is arranged parallel to the axis of rotation of the pins.
  • the mechanical embodiment described below can be installed in front of any barrel winder without modification thereof, the mechanism being made integral with the ground or fixed infrastructure.
  • the bar feeder element 41 is mounted at the end of a crank 43. Concentrically to the bar feeder 41, a loose roller 44 has been mounted, the outside diameter of which is several millimeters (about 10) greater than the width of the 'bar feeder.
  • the roller 44 is intended to roll on the outer surface of the end of the spindle while maintaining the bar feeder at a short distance from the spindle, parallel to its axis. We will see later how this operation is carried out.
  • the bearing 45 carrying the crank 43 is fixed at the end of an arm 46; but, in the rest position, the crank is held parallel to the arm and folded against it by the effect of a torsion spring 47 which exerts its force in the counterclockwise direction; the crank is therefore in abutment on the cleat 48.
  • the arm 46 is articulated in a bearing 49 integral with the support 50. Its movement is given by a rotary actuator 51 controlled by the distributor 8.
  • crank 43 is moved away from the arm 46 by the contact of the roller 44 with the spindle.
  • these devices are positioned in such a way that the grooves of the V-shaped blades 41a or 41b move in planes perpendicular to the axis of the pins, into which the wires have been brought for transfer.
