Abstract

To sever the slubbing at a bobbin for automatic bobbin (1) doffing at the spindle rail, to allow the operative to grip the slubbing end and secure it, the slubbing is brought down to the bottom of the bobbin (1) at the end of winding. The slubbing is wound several times round the bobbin base and then brought upwards into a restricted over-winding. It is then brought down to sever the slubbing at the upper part of the bobbin. <IMAGE>

Description

La présente invention concerne le domaine de l'industrie textile, en particulier les bancs à broches pour fibres longues et notamment la levée automatique destinée à débarrasser lesdits bancs des bobines pleines et à les remplacer par des bobinots vides, et a pour objet un procédé de casse de la mèche en vue de la levée automatique des bobines sur des bancs à broches et un doigt presseur mis en oeuvre par ce procédé.The present invention relates to the field of textile industry, in particular the benches with spindles for long fibers and in particular the automatic lifting intended to rid said benches of full bobbins and to replace them by empty bobbins, and has for its object a method of breakage of the wick for the automatic lifting of the coils on pin benches and a pressing finger implemented by this process.

Actuellement, les bancs à broches pour fibres courtes, telles que les fibres de coton, sont généralement équipés d'une levée automatique des bobines, l'opération de levée automatique étant relativement aisée, tandis que sur les bancs à broches pour fibres longues cette opération est beaucoup plus difficile à réaliser.Currently, the benches with spindles for short fibers, such as cotton fibers, are generally equipped with an automatic lifting of the spools, the automatic lifting operation being relatively easy, while on the benches with spindles for long fibers this operation is much more difficult to achieve.

En effet, pour pouvoir effectuer le retrait des bobines pleines, il est nécessaire de rompre la mèche et, en outre, cette dernière doit être rompue à la sortie de la cuillère du doigt presseur. Cette opération est réalisée sans difficulté en présence de fibres courtes, telles que les fibres de coton, le chariot portant les bobines pleines étant simplement affecté d'un mouvement de descente après l'arrêt des bobines et des ailettes. Ce mouvement de descente a pour conséquence une rupture de la mèche de chaque bobine à la sortie de la palette du doigt presseur, comme souhaité.Indeed, to be able to carry out the withdrawal of the full reels, it is necessary to break the wick and, in addition, the latter must be broken at the outlet of the spoon of the pressing finger. This operation is carried out without difficulty in the presence of short fibers, such as cotton fibers, the carriage carrying the full bobbins being simply affected by a downward movement after the bobbins and the fins have stopped. This downward movement results in a rupture of the wick of each coil at the outlet of the pallet of the pressing finger, as desired.

Dans le cas de fibres longues, cette manoeuvre ne permet absolument pas d'obtenir le même résultat, la mèche de fibres longues se rompant dans le tube de l'ailette et non à la sortie de la cuillère du doigt presseur, ce qui a pour effet que tout automatisme est rendu inutile, un réenfilage de toute la machine étant à chaque fois nécessaire.In the case of long fibers, this operation absolutely does not allow the same result to be obtained, the wick of long fibers breaking in the tube of the fin and not at the outlet of the spoon of the pressing finger, which has the effect that all automation is made unnecessary, re-threading of the entire machine is necessary each time.

En effet, les mèches de fibres longues, à savoir dont les fibres présentent une longueur moyenne comprise entre 5 cm et 20 cm, ne cassent pas toujours au même endroit et présentent généralement un point faible à un endroit où la mèche est détendue.In fact, long strands of fibers, namely whose fibers have an average length of between 5 cm and 20 cm, do not always break in the same place and generally have a weak point at a place where the wick is relaxed.

En outre, l'opération de bobinage se terminant généralement dans la partie supérieure de la bobine, il est nécessaire d'obtenir un enroulage correct de l'extrémité de la mèche cassée afin de permettre le transport de ladite bobine sans risque de déroulage.In addition, the winding operation generally ending in the upper part of the coil, it is necessary to obtain a correct winding of the end of the broken wick in order to allow the transport of said coil without risk of unwinding.

Enfin, il est également nécessaire, afin de pouvoir redémarrer automatiquement un nouveau cycle de bobinage, que l'extrémité cassée de la mèche, au niveau du doigt presseur, soit parfaitement disponible.Finally, it is also necessary, in order to be able to automatically restart a new winding cycle, that the broken end of the wick, at the pressing finger, is perfectly available.

Par FR-A-2 665 188 il a été proposé d'arrêter la machine à une distance proche de l'inversion basse à la fin du bobinage, puis de réarmer les organes de renvidage du banc à broches et de descendre simultanément le chariot au-delà de la matière bobinée. Un bobinage de quelques spires est réalisé ensuite sur l'extrémité haute du bobinot, puis l'alimentation de la mèche est arrêtée tout en effectuant une surtorsion de celle-ci pendant quelques tours. Une réserve de mèche est alors délivrée et le chariot est remonté, ce qui entraîne la casse de la mèche avant une redescente du chariot en position de doffing ou levée automatique des bobines pleines.By FR-A-2 665 188 it has been proposed to stop the machine at a distance close to the low inversion at the end of the winding, then to rearm the rewind members of the spindle bench and simultaneously lower the carriage to the beyond the wound material. A winding of a few turns is then carried out on the upper end of the bobbin, then the supply of the wick is stopped while carrying out an over-twisting thereof for a few turns. A wick reserve is then delivered and the carriage is reassembled, which leads to the breakage of the wick before a descent of the carriage into the doffing position or automatic lifting of the full reels.

La solution proposée par ce document permet, certes, de réaliser la casse d'une mèche tout en assurant que le bout de celle-ci soit parfaitement enroulé sur la bobine et que le redémarrage automatique d'un nouveau cycle soit possible, mais, du fait que le bout cassé est disponible relativement haut sur la bobine, elle pose un problème aux opérateurs en ce qui concerne la récupération du bout de mèche restant sur la bobine pleine, lorsque celle-ci est suspendue au râtelier du continu à filer.The solution proposed by this document allows, of course, to break a wick while ensuring that the end of it is perfectly wound on the spool and that the automatic restart of a new cycle is possible, but, the the fact that the broken end is available relatively high on the spool, it poses a problem for operators with regard to the recovery of the end of the wick remaining on the full spool, when the latter is suspended from the continuous spinning rack.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un procédé de casse de la mèche en vue de la levée automatique des bobines sur des bancs à broches caractérisé en ce qu'il consiste essentiellement, à la fin du bobinage, à arrêter le renvidage dans la partie inférieure de la bobine, à effectuer ensuite un sous-renvidage de quelques tours à la base de la bobine, puis à remonter et à effectuer un sur-renvidage limité suivi d'une descente et d'une casse de la mèche sous la partie supérieure de la bobine.It has, in fact, for its object a method of breaking the wick with a view to the automatic lifting of the coils on pin benches, characterized in that it essentially consists, at the end of the winding, in stopping the winding in the part lower reel, then perform a sub-winding of a few turns at the base of the coil, then go up and perform a limited over-winding followed by a descent and a breakage of the wick under the upper part of the coil.

L'invention a également pour objet un doigt presseur mis en oeuvre par ce procédé, caractérisé en ce qu'il comporte une cuillère pourvue de deux talons, respectivement supérieur et inférieur.The invention also relates to a pressure finger implemented by this method, characterized in that it comprises a spoon provided with two heels, respectively upper and lower.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels:

  • les figures 1 à 4 représentent, en élévation frontale, les diverses phases du procédé selon l'invention ;
  • les figures 5 et 6 représentent, également en élévation frontale, à plus grande échelle, la saisie manuelle de la mèche dans la partie inférieure de la bobine ;
  • la figure 7 est une vue partielle en élévation frontale d'un doigt presseur pour la mise en oeuvre du procédé conforme à l'invention, et
  • la figure 8 est une vue en élévation latérale de la cuillère du doigt presseur.
The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figures 1 to 4 show, in front elevation, the various phases of the method according to the invention;
  • Figures 5 and 6 show, also in front elevation, on a larger scale, the manual entry of the wick in the lower part of the coil;
  • FIG. 7 is a partial front elevation view of a pressing finger for implementing the method according to the invention, and
  • Figure 8 is a side elevational view of the spoon of the pressure finger.

Conformément à l'invention et comme le montrent plus particulièrement les figures 1 à 4 des dessins annexés, le procédé de casse de la mèche en vue de la levée automatique des bobines 1 sur des bancs à broches consiste essentiellement, à la fin du bobinage, à arrêter le renvidage dans la partie inférieure de la bobine 1 (figure 1), à effectuer ensuite un sous-renvidage de quelques tours à la base de la bobine 1 (figure 2), puis à remonter et à effectuer un sur-renvidage limité (figure 3) suivi d'une descente et d'une casse de la mèche sous la partie supérieure de la bobine 1 (figure 4).In accordance with the invention and as shown more particularly in FIGS. 1 to 4 of the appended drawings, the method of breaking the wick for the automatic lifting of the coils 1 on spindle benches essentially consists, at the end of the winding, to stop the winding in the lower part of the reel 1 (figure 1), then to carry out a sub-rewinding of a few turns at the base of the reel 1 (figure 2), then to go back up and to carry out a limited over-rewinding (Figure 3) followed by a descent and a breakage of the wick under the upper part of the coil 1 (Figure 4).

Ce procédé permet à l'opérateur de saisir le bout de la mèche à la base de la bobine 1 et garantit une bonne tenue de la mèche lors des manipulations de la bobine, évitant son déroulage intempestif.This process allows the operator to grasp the end of the wick at the base of the reel 1 and guarantees a good hold of the wick when handling the reel, avoiding its unwanted unwinding.

Selon une caractéristique de l'invention, le sur-renvidage, en partie supérieure de la bobine 1, est effectué sur une longueur suffisante pour assurer le maintien de la mèche lors des manipulations de la bobine 1 et pas trop importante, afin de toujours permettre un glissement de la mèche lors d'une traction.According to a characteristic of the invention, the over-winding, in the upper part of the reel 1, is carried out over a length sufficient to ensure the maintenance of the wick during handling of the reel 1 and not too great, in order to always allow slip of the wick during a pull.

De préférence, le sur-renvidage, en partie supérieure de la bobine 1, est effectué sur une longueur correspondant à environ un demi à un tour de ladite bobine 1.Preferably, the over-winding, in the upper part of the reel 1, is carried out over a length corresponding to approximately half a revolution of said reel 1.

Ainsi, comme le montre la figure 5, le procédé conforme à l'invention permet une disposition de la mèche sur la bobine pleine dans laquelle l'opérateur peut saisir le bout de la mèche à la base du bobinot lorsque la bobine 1 est accrochée au râtelier du continu à filer et l'amener dans la position représentée à la figure 6, même si la bobine 1 est entourée d'autres bobines.Thus, as shown in Figure 5, the method according to the invention allows an arrangement of the wick on the full reel in which the operator can grasp the end of the wick at the base of the bobbin when the coil 1 is attached to the rack of continuous spinning and bring it into the position shown in Figure 6, even if the reel 1 is surrounded by other reels.

En outre, la disposition de la mèche conformément à l'invention permet la manutention des bobines pleines, tout en évitant le risque de déroulage du fait de l'existence d'une boucle 3 réalisée autour de la partie supérieure de la bobine 1 (figures 3 à 5).In addition, the arrangement of the wick in accordance with the invention allows the handling of full reels, while avoiding the risk of unwinding due to the existence of a loop 3 produced around the upper part of the reel 1 (FIGS. 3 to 5).

L'invention a également pour objet un doigt presseur 2 mis en oeuvre par ce procédé et destiné à déposer la mèche sur le bobinot pour former la bobine 1, qui comporte un cône supérieur et un cône inférieur. A cet effet, comme le montrent les figures 7 et 8 des dessins annexés, le doigt presseur 2 comporte une cuillère 5 pourvue de deux talons, respectivement supérieur 6 et inférieur 7, dirigés respectivement vers le haut et vers le bas. Ces talons 6 et 7 sont destinés à permettre à la cuillère 5 à passer sur les cônes correspondants de la bobine 1 vers la grande base. Du fait du procédé conforme à la présente invention, la cuillère 5 passe successivement sur le cône inférieur puis sur le cône supérieur, ce qui entraîne la prévision des talons supérieur 6 et inférieur 7.The invention also relates to a pressing finger 2 used by this method and intended to deposit the wick on the bobbin to form the coil 1, which comprises an upper cone and a lower cone. To this end, as shown in Figures 7 and 8 of the accompanying drawings, the pressing finger 2 comprises a spoon 5 provided with two heels, respectively upper 6 and lower 7, directed respectively upwards and downwards. These heels 6 and 7 are intended to allow the spoon 5 to pass over the corresponding cones of the coil 1 towards the large base. Due to the process according to the present invention, the spoon 5 passes successively on the lower cone then on the upper cone, which leads to the forecast of the upper 6 and lower 7 heels.

Grâce à l'invention il est possible de réaliser un cycle de casse de la mèche permettant aux opérateurs de saisir facilement et sûrement la mèche, au bas de la bobine pleine 1.Thanks to the invention it is possible to carry out a breakage cycle of the wick allowing the operators to easily and surely grasp the wick at the bottom of the full reel 1.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, notably from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
