Definitions
- the present invention relates to the manufacture of wire windings of glass wound at constant speed, and in the form frustoconical windings.
- Wire wraps are a common means of storage temporary said thread which may take different forms: thread simple with twist, twisted yarn, etc. They are later used to supplying thread to textile machines operating at high speed. The wire should then be able to be easily extracted from it, avoiding any friction which could cause a break. In this area, the windings frustoconical have a particular advantage over others forms of windings. Indeed the wire, dragged along the axis of the winding towards its smallest diameter therefore deviates immediately from the side of the coil as soon as a turn comes off. The risk that a turn is retained by an adjacent turn or that the wire come to rub on the side of the winding is very weak.
- Some of the known solutions are intended to maintain substantially constant winding speed of the wire despite the variation continuous diameter of the support on which it is deposited. For this it is necessary to vary the speed of rotation of the support so that the wire constantly encounters a surface whose peripheral speed is substantially constant. The support being rotated by motor rollers this maintenance of the peripheral speed cannot be obtained only by alternating braking and rapid acceleration of said rollers.
- Another difficulty is to avoid the pressure exerted by necessarily the motor rollers on the coil, does not damage the wire. That is all the more difficult to avoid when the wire is sensitive to the friction of by its very nature; this is particularly the case with glass strands.
- rollers motors such as US-A-3,218,004.
- This patent describes a process which makes it possible to produce a winding. frustoconical on a cylindrical support provided with a straight side to each of its ends. This result is achieved through a variation concomitant with the speed of the thread guide and the speed of rotation of the pin carrying the support.
- the variation of the spindle speed is caused by the variation of the engine torque, itself caused by the variation of the thread tension during its winding.
- This process has a certain inertia and is only applicable to wires whose mechanical behavior allows them to absorb variations in tension, such as metal wire, but it is not applicable to wire which do not have this capacity to absorb such variations in tension like glass threads.
- the present invention relates to a method for obtaining directly, from a die from which glass filaments are drawn continuous gathered in the form of a wire, a frustoconical winding of said wire.
- the subject of the present invention is in particular a process which allows to directly obtain a frustoconical winding, that the support on which the wire is wound either cylindrical or frustoconical.
- the objects of the invention are achieved by a method according to which, continuous glass filaments are drawn mechanically from of a multiplicity of molten glass streams flowing from the orifices of a die, then are coated with a size and gathered in a thread which is driven by a stretching device, and which consists, downstream of this device, passing said thread to the end of the arm of a dancer roller and then wind on a support fixed by one of its ends to a spindle rotated and to distribute the quantity of thread deposited on said support using a thread guide moving in a movement back and forth parallel to the axis of said support so as to obtain a frustoconical winding over at least part of its height, in assigning a constant value to the speed of rotation of the device drawing, by programming the speed of movement of the thread guide and the length of its path, by continuously measuring the difference between the speed constant wire drawing and its winding speed thanks to the movement of the dancer roller arm and by controlling the speed of spindle rotation away so measured so that for each path of the thread guide
- the spindle speed can be controlled or controlled in different ways. Thus, it can be slaved in real time to movement of the arm carrying the dancer roller using a regulator PID action, connected to the motor of said spindle via a frequency converter.
- It can also be controlled by the movement of the arm carrying the roller dancer using a PID action regulator whose parameters regulation are programmed by a PLC, said regulator being connected to the spindle motor via a frequency converter.
- roller arm dancer whose signal is transmitted to an automaton which, after conversion and calculation according to the programmed parameters, in turn transmits information to the frequency converter connected to the spindle motor.
- the rotational speed of the spindle can be controlled, via a dimmer frequency, by a programmed automaton, said command being corrected after comparison with the signals transmitted to the automaton by the arm of the pebble dancer when depositing layers n-1; n-2 ... n-p.
- the speed of movement of the wire guide for depositing each layer of wire can vary between at least two extreme values from the start to the end of the winding operation.
- the speed of the wire guide can vary for example between two extreme values v 1 and v 2 for each layer deposited from the start of the winding operation to a predetermined layer ⁇ n ⁇ .
- the speed of the thread guide can remain constant between its cusp points.
- the variation of the speed of the thread guide and the concomitant variation of the spindle speed thus makes it possible to vary the length of wire deposited on any portion of the surface of winding, considered during at least part of the operation of winding and between two parallel planes one centimeter apart and perpendicular to the axis of said winding, for the whole or for part of the layers of wire, according to the frustoconical shape desired for the final winding.
- the length of wire deposited on the portion of surface defined above will be called ⁇ length of wire by centimeter ⁇ in the following description.
- the frustoconical shape being able be generated by the only programmable parameters of the operation of winding, the wire can be wound on a cylindrical support as well as on a frustoconical support.
- This support can include one of its ends a straight flank or a tapered flank. The process according to the invention therefore makes it possible, directly from a die, to produce different frustoconical windings of glass wire.
- the speed of the wire guide can remain constant between its cusps from start to finish the winding operation.
- the wire is wound on a support tapered.
- a frustoconical winding by depositing superimposed layers of a wire on a cylindrical support, formed of internal layers deposited at the beginning of the winding operation in which the length of wire deposited by centimeter varies from the top to the base of the winding and layers external with a constant length of deposited wire.
- the height of the layers of wire whose frustoconical winding is formed can gradually decrease from the first layers deposited on the support up to the layer forming the periphery of said winding.
- a frustoconical winding can be obtained by depositing superimposed layers whose height gradually decreases from the first layers deposited on the chosen support winding up to the layer forming the periphery of the winding.
- the speed of the wire guide varies or remains constant between the cusps of said thread guide.
- This installation comprises a die 21, shown schematically, which is normally connected to a power source glass.
- This source can be the fore-body an oven that distributes the molten glass to several similar channels to the die 21, fed by simple gravity.
- Pathway 21 can be supplied from cold glass, obtained and stored in the form of beads in a hopper arranged above the die.
- the die 21 is generally made of platinum-rhodium alloy and heated by joule effect. This process allows the glass to be remelted or kept at a temperature sufficient for a viscosity suitable for drawing it in the form of continuous filaments.
- the molten glass flows out of a multiplicity of orifices, such as nipples 22, and immediately stretched in a multiplicity of filaments 23, gathered here in a single sheet 24.
- the filaments thus obtained have an average diameter generally understood between 5 ⁇ m and 14 ⁇ m.
- This sheet 24 comes into contact with the device shown diagrammatically at 25, so that each filament 23 is coated with a size.
- This device 25 is permanently supplied with a size taken from the passage through the filaments 23 which slide on its surface.
- the type of size deposited is preferably made up essentially of a mixture of organic products. This avoids the inherent drying operation to the use of sizing in aqueous phase and the disadvantages which result.
- the installation will include a device to eliminate the most of the size water deposited on the wire before it is wound. Such a device is described for example in the patent application filed in FRANCE on December 11, 1992 under number 92.14910.
- the ply 24 converges towards the assembly device 26 where the different filaments are brought together to give birth to thread 27.
- This device can consist of a simple grooved pulley or a plate provided with a notch.
- the wire 27, after passing over a member of guide 28 such as for example a pulley with groove, is driven at speed constant by the device 29. This speed is generally equal or greater than 10 meters per second.
- This device illustrated schematically in Figure 3a, consists a drawing wheel 30, driven by a motor not shown, which forms capstan and a separator roller 31 freely rotating around its axis.
- the wire 27 then passes through the groove of a dancer roller 32 freely rotating about its axis fixed at the end of an arm 33.
- a device such as a spring 35, makes it possible to imposing a predetermined tension on the wire 27.
- the arm 33 pivots about its axis. This movement is immediately recorded by the device 36.
- the wire 27 is then wound using a wire guide such as the pulley 37.
- the pulley 37 moved back and forth and moving initially between the two positions p 1 and p 2 , distributes the wire on a barrel 38 provided at its base with a straight flank 39. This support is fixed to a spindle 40 driven in rotation by a motor 41.
- An automaton imposes a speed on the motor of the stretching wheel 30 constant, a condition that must be met to obtain filaments 23 of constant diameter and therefore a wire 27 of constant titer.
- the automaton also imposes on wire guide 37 the speed or speeds of displacement which must be respected during the whole operation of winding to obtain a winding of a determined structure, as well than the length of its stroke.
- the programming of the latter characteristic allows, for example, to progressively reduce the stroke of the thread guide at the start of the winding operation in order to obtain the conical shoulder as shown in Figures 1 and 2.
- this programming also allows you to change the stroke of the thread guide so to deposit the last turns of each layer at a slightly level lower than that reached by the last turns of the previous layer. it is thus possible to prevent an undesirable accumulation of turns shape in the end-of-travel area of the thread guide.
- the winding With a support provided of a frustoconical flank the winding can be formed only of layers with a constant length of wire per centimeter of a end of the winding to the other.
- the displacement or more exactly the rotation of the arm 33 of the roller dancer around his axis, caused by the appearance of a gap between the drawing speed and wire winding speed, is transformed into signal electric by a potentiometer (device 36).
- This signal is transmitted to a proportional and integral proportional action regulator.
- the parameters of this regulator can be set by potentiometers or programmed by the automaton.
- the signal processed by the regulator is transmitted to a frequency converter which controls the motor 41 of spindle 40.
- the rotation of the arm 33 of the dancer roller can also be recorded by an encoder placed on its axis in place of the previous potentiometer.
- the encoder signal is transmitted to the automaton. After calculation according to the programmed parameters, the information is transmitted to the frequency converter which controls consequently the motor 41.
- the previous regulation is a reactive regulation in real time depending on the movement of the dancer roller. With a more complex programming, it can be of the digital-predictive type with analog corrections.
- the automaton after calculation according to parameters programmable, transmits information to the drive which controls the motor 41. Any rotation of the dancer roller arm is then recorded by the encoder fixed on its axis. The signal provided by the encoder is transmitted to the PLC. The controller after calculation and correction transmits a information modified to the drive, etc ...
- FIGS 1 and 2 schematically illustrate two examples glass wire windings obtained according to the invention.
- each layer deposited since the start of the winding operation exhibits a very significant variation in the length of wire deposited by centimeter from the top of the coil to its base. That is symbolized, in zone 13, by a series of layers whose thickness strongly increases from the top of the cylindrical barrel 11 to right flank 12. This type of deposit is made until the shape is obtained frustoconical desired for the final winding.
- the following layers can then have a length of deposited wire per centimeter constant over their entire height. This is symbolized by layers 14 of constant thickness. In reality the thickness of these layers is not rigorously constant from the start to the end of the winding operation. We can observe a very slight difference in the taper of the winding due at its magnification. Winding 10 also has a shoulder conical.
- FIG. 2 illustrates another type of winding 16 produced on a bole frustoconical 17 provided with a frustoconical flank 18.
- the layers deposited include a length of deposited wire per centimeter that remains constant over their entire height. This is symbolized by 19 layers of constant thickness.
- This winding also has a frustoconical shoulder 20.
- the table in the appendix gives, as examples, the characteristics and the manufacturing parameters of two kinds of windings frustoconical shaped according to the invention. These windings were obtained from a 68 tex thread, formed from 408 glass filaments, of a diameter average of 9 micrometers, stretched to 2220 meters per minute.
- the size deposited on these filaments has the following composition, expressed in weight percentages: ⁇ isobutyl stearate 4.25% ⁇ silicone acrylate (sold under the reference Ebecryl 1360 by the company Union Chimique Belge) 14.25% ⁇ carbonate diacrylate (marketed under the reference Acticryl CL 993 by the company Harcros) 14.25% ⁇ N-vinyl pyrrolidone 33.25% ⁇ ethoxylated trimethylolpropanetriacrylate (sold under the reference SR454 by the company Cray Vallée) 19.00% ⁇ 1-hydroxycyclohexyl phenylketone (sold under the reference Irgacure 184 by the company Ciba-Geigy) 10.00% ⁇ ethoxylated trimethoxysilane (sold under the reference Silane Y 5889 by the company Union Carbide) 5.00%
- the winding n ° 1 was carried out on a cylindrical barrel provided with a straight side; winding n ° 2 on a frustoconical barrel also provided with a straight flank. These two windings have a conical top.

- Procédé selon la revendication 1, caractéristique en ce que la vitesse de rotation de la broche est asservie au déplacement du bras portant le galet danseur à l'aide d'un régulateur à action PID dont les paramètres de régulation sont programmés par un automate, ledit régulateur étant relié au moteur de la broche par l'intermédiaire d'un variateur de fréquence.
- Procédé selon la revendication 1, caractérisé en ce que la vitesse de rotation de la broche est asservie au déplacement du bras du galet danseur dont le signal est transmis à un automate qui, après conversion et calcul en fonction des paramètres programmés, transmet une information au variateur de fréquence relié au moteur de ladite broche.
- Procédé selon la revendication 1, caractérisé en ce que la vitesse de rotation de la broche est commandée pour le dépôt d'une couche 〈〈 n 〉〉, par l'intermédiaire d'un variateur de fréquence, par un automate programmé, ladite commande étant corrigée après comparaison avec les signaux transmis à l'automate par le bras du galet danseur lors du dépôt des couches n-1, n-2, ... n-p.
- Procédé selon l'une quelconque des revendications 1 à 5, caractérisé en ce que le fil est entraíné et bobiné à une vitesse linéaire au moins égale à 10 mètres par seconde.
- Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que la vitesse de déplacement du guide-fil, pour le dépôt de chaque couche, varie entre au moins deux valeurs extrêmes depuis le début jusqu'à la fin de l'opération de bobinage.
- Procédé selon l'une quelconque des revendications 1 à 6, caractérisé en ce que la vitesse de déplacement du guide-fil, pour chaque couche déposée au début de l'opération de bobinage, varie entre au moins deux valeurs extrêmes, ladite vitesse demeurant ensuite constante entre les points de rebroussements dudit guide-fil pour le dépôt des couches suivantes jusqu'à la fin de l'opération de bobinage.
- Procédé selon la revendication 1 à 6, caractérisé en ce que la vitesse de déplacement du guide-fil est constante entre les points de rebroussements dudit guide-fil du début à la fin de l'opération de bobinage.
- Procédé selon l'une des revendications 1 à 6, caractérisé en ce que la longueur de la course du guide-fil décroít pendant au moins une partie de la durée de l'opération de bobinage.
- Procédé selon l'une quelconque des revendications 1 à 6, caractérisé en ce que les couches de fil sont superposées sur un support cylindrique.
- Procédé selon l'une des revendications 1 à 6, caractérisé en ce que les couches de fil sont superposées sur un support tronconique.
- Enroulement de fil de verre obtenu selon le procédé défini par l'une quelconque des revendications précédentes, caractérisé en ce qu'il est formé d'un fil constitué de filaments dont le diamètre moyen est compris entre 5 et 14 micromètres.
- Enroulement selon la revendication 13, caractérisé en ce qu'il est formé d'un fil revêtu d'un ensimage constitué pour l'essentiel d'un mélange de produits organiques.
- Enroulement selon l'une des revendications 13 ou 14, caractérisé en ce qu'il est bobiné sur un support cylindrique ou tronconique.
- Enroulement selon la revendication 15, caractérisé en ce que le support comprend un flanc droit ou tronconique à l'une de ses extrémités.
