Definitions

  • the present invention relates to an improvement made to the control members of the reciprocating device of the wire distributing guides during a winding operation.
  • It relates more particularly to an improvement made to the means making it possible to vary the length of the displacements of the wire guides, so as to produce windings of biconical shape.
  • a cam system which transmits back and forth movement to a support body of the wire guide.
  • the wire guide is pivotally mounted on the support body by means of an assembly essentially consisting of two arms arranged at right angles, the wire guide being disposed at the end of the one of the arms, and the end of the other arm being equipped with a roller sliding along a groove made in a bar called "sine bar"; it is known, moreover, that by modifying the inclination of this bar, it is possible to vary the stroke of the thread guide, this combined with a clock or in connection with the magnification of the spool, which makes it possible to make conical windings.
  • the distribution of the wire is carried out by means of a back-and-forth guide (4), such as a vibrator, driven by a cam (5) itself controlled in rotation by means of a set of gears (6) by means of an electric motor (7).
  • the vibrator (4) is carried by a carriage, not shown, associated with a "sine bar” type system also not shown.
  • the tube (2) on which the wire is wound is itself rotated, also by means of a set of pinions (8) by an electric motor (9), the speed varies according to that of the winding (3) and is controlled by contact with the pilot roller (1).
  • the motor (7) is supplied with direct current and the speed of said motor (7) is modified, synchronism with the magnification of the winding (3) by means of a potentiometer controlled by a cam.
  • the arm (12) of the winding gripping fork (3) carries at its free end a cam (11) on which a roller (13) is supported, itself rigidly connected by a lever (14) to the axis of the potentiometer (10).
  • a spring (15) allows the roller (13) to be returned.
  • the invention therefore relates to an improvement made to the control and displacement system of the thread guide during the production of a biconical spool on textile machines comprising a plurality of identical working positions arranged side by side. each other, false twist texturing machines in particular, each winding assembly of each position being of the type comprising a pilot roller driven in rotation at constant speed and against which a wire support rests on which the winding of wire by means of a wire guide animated by a reciprocating movement communicated by a rotary grooved cam, each working position also comprising means for varying the stroke of the reciprocating movement as as the winding magnifies thanks to a conventional "sine bar" type system, while keeping the winding pitch constant.
  • FIGS. 3 and 4 illustrate the structure and operation of a winding device produced in accordance with the invention and which makes it possible to obtain coils of biconical wire in which the pitch or crossover of the wire is constant over the entire thickness of winding.
  • a winding device is particularly suitable for textile machines such as texturing machines by false twist, comprising a large number of working positions arranged side by side over the entire length of the machine.
  • Figures 3 and 4 therefore illustrate the winding system of a working position, it being understood that in an industrial machine, there are a large number of similar winding systems side by side.
  • Each winding system comprises, produced in a conventional manner, a pilot roller (21) driven in rotation at constant speed by conventional means not shown such as a single electric motor for all of the working positions.
  • This pilot roller (21) drives, by tangential contact, a tube (22), made of cardboard for example, on which a biconical bearing (23) is formed with constant pitch produced in accordance with the invention.
  • the tube (22) is held between the arms of a gripping fork (24) which can pivot around an axis parallel to the drive shaft (22) as the winding grows ( 23) when winding the wire.
  • the distribution of the wire for making a biconical winding is obtained by a conventional assembly (25), partially illustrated in the appended figures, which essentially comprises a rotary cam (26) making it possible to ensure the movement back and forth to a thread guide (39) and, on the other hand, a so-called “sine bar” assembly (27) allowing, as and when it is inclined, to vary the stroke of the thread guide (39) and this in synchronism with the magnification of the coil.
  • the speed of rotation of the rotary cam is varied in synchronism ( 26).
  • the set of cams (26) controlling the reciprocation of the wire guide (39) associated with each position is controlled by a single motor shaft (28) extending over the entire length of the machine and driven by a motor (29) rotating at constant speed.
  • each cam (26) of each position as the winding increases are obtained by means of a cone variator (30) associated with each winding system and whose the position of each transmission belt (31) is automatically changed in synchronism with the position of the bar / sine assembly (25) of the winding system.
  • Such synchronized movement is obtained by means of a fork (32) integral with a pivoting lever (33) and connected to the end (38) of the sine bar (27).
  • the movement of the bar / sine assembly (27) is controlled directly as the wire winding increases by associating with a fork arm (24), a cam (34) against which s 'supports a roller (35) mounted at the end of a lever (36) itself articulated at (37) on the bar / sine assembly (27). Consequently, thanks to such an assembly, at the start of winding as shown in FIG. 3, zone where the amplitude of the reciprocating of the thread guide (39) is the greatest, the cam (26) is driven at some high speed.
  • the rod / sine assembly (27) is controlled to progressively reduce the stroke of the thread guide (39 ) and, simultaneously, the position of each belt (31) of the cone variators (30) is displaced, thereby reducing the speed of rotation of the cam (26) and making it possible to obtain a constant winding pitch.
