Definitions

  • the present invention relates, in general, to the technique of winding threads and it relates, more particularly, to winders intended for winding threads of thermoplastic material such as glass threads drawn from a Faculty.
  • winders have already been developed in which a yarn guide in the form of a fork is provided in which the wire to be wound passes, the latter possibly originating in particular from a die.
  • the thread guide is placed as close as possible to the winding intended to form the reel and moved back and forth in a direction which, for reels of cylindrical shape, is parallel to the axis of the spindle around which the coil is formed.
  • the amplitude of the back-and-forth movement corresponds approximately to the height of the coil produced, that is to say to the length of the generator thereof.
  • Winders of this type have already been described in the following US patents: 3,367,587, 3,371,877, 3,498,550, 3,547,361, 3,717,311, 3,897,021. 3,801,032, 3,819,122, 3,838,827 and 3,845,912.
  • a winder comprising a fixed frame in which is rotatably mounted a spindle intended to receive the wire to be wound.
  • This spindle is coupled to rotational drive means which also act on a wire guide assembly in order to drive the wire guide in a reciprocating movement, the assembly being mounted oscillating in the frame.
  • the winder further comprises a control device intended to cause the rotation of the thread guide assembly in the direction of the distance from the spindle, as a function of the growth of the radius of the spool during formation.
  • This control device comprises an adjustment loop formed by a probe intended to detect the growth of the coil, a motor device intended to rotate the arm and an excitation element of the motor device according to the position of the probe.
  • the probe is made in the form of a roller coming into contact with the spool, while the wire guide is placed immediately above the roller.
  • the thread passes through the thread guide and then under the roller, which it leaves to wind up on the spool.
  • the roller which is fixed on the swinging arm is returned to the coil by an elastic device produced in the form of several pneumatic cylinders.
  • the swinging arm can, in its recoil movement under the effect of the magnification of the coil, activate an electrical contact or proximity sensor which constitutes the excitation element and which acts when it is closed on the motor device to make move the swing arm back.
  • the device described in patent US-A-3,717,311 comprises a roller coming into contact with the coil, said roller being directly fixed on the reciprocating mechanism which is itself fixed on a carriage moving horizontally.
  • This carriage is constantly returned to the coil by a constant force given by a pneumatic cylinder whose thrust is adjustable.
  • a pneumatic cylinder whose thrust is adjustable.
  • the principle of operation is simple, but it does not allow the roller to be applied to the coil with a sufficiently low and constant force.
  • the pneumatic cylinder can be adjusted with precision, the force of application of the roller on the reel is disturbed by parasitic friction such as that of the piston in the cylinder, that of the carriage on its slides and that of the joints of the driving force transmission device to the back and forth movement.
  • this friction is very variable due to the fouling of the sliding surfaces caused by the projections of size and fiber debris.
  • the detection system is a contactless device constituted by a pneumatic pressure gauge provided with different nozzles and supplied with pressurized air, integral with the reciprocating mechanism.
  • Gaseous jets directed permanently by certain nozzles against the surface of the coil give rise to reflected gas currents, captured by another nozzle.
  • This pressure varia authorizes .r, command to open a pressure air admission valve in a pneumatic cylinder, which causes the device to move away from and back.
  • the main defect of this device is due to the use of a compressible fluid as a detection agent and as a motive agent.
  • the irregularity of the surface detected and the combined effect of the centrifugation of air by the rotating coil cause fluctuations in the reflected gas currents and therefore parasitic pressure variations.
  • the device described is not immune to friction which results in the admission into the cylinder of a quantity of air under pressure greater than that normally required to move the mechanism away. back and forth. As a result, the distance between the wire guide and the spool does not remain constant.
  • the object of the invention is to provide a winder of the above-mentioned type, but devoid of the drawbacks which have just been mentioned.
  • thermoplastic material such as glass son stretches from a die, characterized in that its excitation element is a continuously controlled element.
  • the assembly constituted by the feeler roller and its support is balanced by simple gravity and associated with a simple device making it possible to rigorously adjust the pressure exerted by the feeler roller on the outer surface of the coil.
  • Patent BE-A-532,616 describes a device allowing the winding of wires on a spindle driven in rotation by a friction cylinder.
  • the ends of the spindle or of the cylinder are provided with rolling rings intended to ensure the rotation of the spindle at the start of the wire winding process.
  • This arrangement allows the spindle to start, to wind the wire at an increasing speed without the latter coming into contact with the friction cylinder, and therefore to avoid deterioration of the wire.
  • the diameter of the rings is such that the friction cylinder comes into contact with the wound wire, when the peripheral speeds of the spindle and the cylinder are practically equal.
  • This device however has certain drawbacks compared to the winder defined in claim 6. Indeed, the arrangement of the rings at the ends of the spindle ( Figure 1) does not allow the establishment, then the removal of cuffs supporting the winding sons.
  • the winder is associated with a die A which continuously produces a certain number of filaments B which are coated in a coating device C and assembled by a roller D, the resulting thread E being led to the winder.
  • the latter comprises a frame 1 in which is rotatably mounted about an axis X-X a spindle 2 intended to receive sleeves such as F engaged on this spindle and intended to respectively constitute the cores of the coils to be formed.

  • the journal 13 disposed near the free end of the body 8 extends beyond the bearing 11 and is secured at its free end to a lever 16 which exactly follows the oscillating movements of the oscillating support 12.
  • the end of this lever 16 opposite the pin 13 is forked and engaged on a pin 17 secured to a caliper 18.
  • the latter is fixed to the slide 19 of an adjustment valve 20 (see also fig. 2 and 3) which forms the excitation element of the winder control loop.
  • a spring 21 attached on the one hand to a lug 22 of the lever 16 and on the other hand to a tension adjustment device 23 mounted on the end face of the body 8 is arranged so as to urge the entire support 12 and of the lever 16 in a direction which brings the probe 14 closer to the axis of rotation XX of the spindle 2.
  • Figs. 1 to 3 also show that the spindle 2 is provided with a peripheral flange 24 which is intended to cooperate with an elastomer flange 25 for example, provided on the feeler roller 14 and, as will be seen later, bringing these flanges 24 and 25 into contact is intended to facilitate the starting of the roller 14.
  • the respective diameters of these flanges 24 and 25 are calculated to obtain at the start of winding a peripheral speed of the feeler roller at most equal or preferably slightly lower than the peripheral speed of the cuff F .

  • the adjusting device 23 of the spring 21 is intended to adjust the pressure by which the feeler roller 14 is supported on the reel being formed.
  • a lever 26 integral in rotation with the oscillating arm 6 is connected at its free end to the rod of a jack 27 which constitutes the motor device of the winding adjustment loop.
  • the jack 27 is mounted oscillating on a mounting plate fixedly mounted in the frame 1 and supports various control members shown in detail in fig 5. In fig. 1, it can be seen that if the rod of the jack 27 is retracted, the oscillating arm 6 moves around the axis YY in the direction of the arrow f1 in order to move the mobile assembly which it carries away from the axis XX of spindle 2 of the winder.

  • the bearings 33 are protected by baffles 34 against dust and other sails which may result from the winding.
  • nozzles 35 are provided mounted in the body 8 on either side of the support 12 and connected to a pressurized water circuit 36.

  • the pipe 39 is connected to the inlet of an oleopneumatic valve 41, the outlet of which is connected on the one hand to the pipe 37 and on the other hand by a pipe 42 to another air-oil exchanger 43.
  • the air inlets of the exchangers 40 and 43 are connected to a distributor 44 with five ports and pneumatically controlled allowing the exchangers 40 and 43 to be placed in communication either with a pneumatic pressure source or with the atmosphere, under the control of the pressure prevailing in a pipe 45.
  • the oleo-pneumatic valve 41 is connected by a pipe 46 to the output of a pneumatic logic gate 47 of "OR" function, the first input of which is connected to the pipe 45 by a pipe 48. Its other inlet is connected by a pipe 49 to another "OR" logic gate 50, a first of which is connected to a memory element 51 and a second input of which is connected by a pipe 52 to a valve 53 with manual control which is intended to cause the distance from the moving element formed by the arm 6 and the body 8 of the axis XX of the spindle 2.
  • the valve 53 is associated with a solenoid valve 54 for automatic control of this moving away, this valve being connected to one of the inputs 55 of the memory element 51, the other input 56 of this element being connected by a pipe 57 to a valve 58 of the end of the travel limit which is actuated to put the pipe 57 under pressure when the piston of the cylinder 27 is in its position extreme lower.
  • Line 48 is also connected to the outlet of an "OR" pneumatic door 59, a first inlet of which is connected by line 60 to a manual control valve 61 making it possible to initiate the movement of movement of the aforementioned moving element of the axis XX of spindle 2.

  • the operator acts on the valve 53 for manual control of the distance.
  • the wire guide 10 After the end of the winding, the wire guide 10 must be moved away. This operation can be carried out automatically or manually using the valves 53 and 54.
  • the feeler roller 14 When the winding operation begins, the feeler roller 14 is not yet in contact with the cuff F arranged on the spindle 2 (see fig. 2), but since the latter is rotated by the means of drive 3, the flange 24 of this pin rotates the flange 25 of the feeler roller 14.
  • the spool When the thickness wound on the sleeve F reaches a thickness of 1 to 2 mm, that is to say greater than the total thickness of the flanges 24 and 25, the surface of the coil being formed comes into contact with the feeler roller 14. While continuing to grow, the spool then repels the roller 14 which is permanently applied to it thanks to the effect of the tension spring 21, with a predetermined force of a few newtons.
  • the roller 14 pivots the oscillating support 12 around the pins 13 as well as the lever 16 which is integral with one of these pins.
  • the pressurized oil contained in the exchanger 40 can then cause the rod of the jack 27 to enter, because the oil of the jack being on the side of the piston opposite the rod of the jack can exit through the pipe 38, the valve 20 , lines 37 and 42 and flow back to the exchanger 43, the latter being vented.
  • valve 20 When the valve 20 begins to open, the movement of separation described above has a lower speed than the speed of increase of the radius of the coil. Under these conditions, the feeler roller 14 continues to be pushed back by the coil, which causes an increase in communication between the orifices 31 and 32 of the valve 20. The speed of separation of the crew 6. 8. 10 then increases until it reaches the speed of increase of the radius of the coil. When equal speeds are obtained, the system thus controlled keeps a stable opening through the valve 20.
  • the feeler roller 14 therefore gradually returns to its initial relative position under the effect of the tension spring 21, which has the effect of pushing the slide 19 in the valve 20 and partially closing the orifices 31 and 32, therefore d '' ensure constant equality of speeds away from the feeler roller and increase in the radius of the coil.
  • the moving element 6, 8, 10 is moved away from the axis XX of the spindle 2 thanks to the automatic supply of the solenoid valve 54 which causes the opening of the oleopneumatic valve 41 mounted in parallel on valve 20.

  • This displacement sensor can advantageously be produced in the form of a differential transformer sensor manufactured for example by the firms SCHAEVITZ or NOVOTECHNIK (Federal Germany).
