Definitions

  • the present invention relates to an improvement made to pins used in the textile industry, in particular for twisting threads.
  • Twisting pins are devices which have been known for a very long time and consist essentially of a shaft (or spindle barrel) mounted to rotate freely on the frame of the machine by means of an appropriate bearing.
  • the tube around which the wire is wound is fitted onto the spindle barrel.
  • the spindle barrel, and consequently the spool of wire, can be driven in rotation in different ways.
  • the most widespread solution consists in driving the spindles of the machine by means of an endless belt drive brought into tangential contact with the base of the spindle barrel.
  • the invention relates to an improvement made to such spindles driven by an individual motor.
  • One of the main problems in such individually driven spindles is that of increasing the height of the center of gravity of the spool and the spindle, given that the motor is arranged above of the lower bearing of the system supporting said spindle.
  • Such an embodiment is however of a very complex design and above all does not solve the problem of lowering the center of gravity of the spindle / wire winding assembly towards the fixed frame of the machine, which limits therefore the operating speeds and the weight of the windings.
  • French patent FR-A-2,095,830 describes a solution allowing the height of the center of gravity of the coil and the motor to be reduced.
  • This solution consists in the use of a small motor, especially in height, this motor being constituted by a bipolar electric motor, in particular an asynchronous motor, the stator of which is provided with a flat annular winding. If by the choice of such an engine, a lowering of the center of gravity is logically obtained, the latter always remains nevertheless clearly arranged above the support frame, taking into account the fact that this engine is always disposed above the bearing supporting the spindle, and therefore consequently above said support frame.
  • the invention therefore relates to a twisting spindle, driven by an individual electric motor, according to claim 1.
  • FIG. 1 illustrates a textile machine comprising two twisting pins, designated by the general reference (1), in accordance with the invention.
  • Each of these twisting pins (1) is of the type driven by an individual electric motor (designated by the general reference 2) preferably a bipolar asynchronous motor supplied in a conventional manner (not shown) for example by an alternator.
  • This pin consists essentially by a barrel (3) intended to support the winding of wire (4) (not shown in Figure 1).
  • the barrel (3) is mounted to rotate freely on a support frame (6) constituted in this case by an inverted U-shaped profile, horizontal, attached to the carcass of the machine.
  • This spindle (1) is driven, as said above, by an individual motor (2), motor whose rotor (7) is fixed directly to the barrel (3) by means designated by the general reference (8) making it possible to secure the body (9) (and consequently the stator) of the motor (2).
  • the fixing of the body (9) of the motor (2) as well as the maintenance and the guiding of the spindle barrel are carried out using securing means (8) and this, by the through a rigid sleeve (5) surrounding the barrel (3), this sleeve (5) passing through the frame (6) and serving as a cage for the bearings (10, 11) allowing the spindle (1) to rotate.
  • the sleeve (5) has at its ends two flanges (12, 13), one (12) upper fixed elastically to the frame (6), the other (13) lower secured to the body (9) of the motor ( 2).
  • the means allowing the elastic fixing of the sleeve (5) advantageously consist of studs (14) based on elastomer, these studs (14), in an appropriate number, being in the embodiment illustrated in FIG. 1 , arranged between the upper flange (12) and the upper part of the frame (6) by means of fixing bolts whereas, in the embodiment illustrated in FIG. 2, these means are also constituted by studs (14) but which are arranged on either side of the upper part of the support frame (6), these studs being held by means of bolts (15).
  • the motor (2) is disposed at the end of the barrel (3), the connection of the assembly being produced in an elastic manner and the guiding of the barrel (3) by bearings (bearings 10, 11) arranged on either side of the upper part of the frame (6), it is possible to have a distribution of the masses on either side of the fixing points, and consequently, to bring back the center of gravity of the spindle / motor assembly substantially at the level of the frame (6).
  • Such an embodiment makes it possible to practically completely limit the vibrations and consequently to use a motor having as small an air gap as possible, which can therefore have optimum efficiency.
  • this spindle also has the advantage of being very quiet and, by design, can be easily disassembled, which promotes maintenance.
