Description

La présente invention concerne les machines textiles et, plus particulièrement, les bancs à broches pour fibres longues et fibres courtes, et a pour objet un dispositif de sécurité pour un tel banc à broches pourvu d'un dispositif de levée automatique.The present invention relates to textile machines and, more particularly, pin benches for long fibers and short fibers, and relates to a safety device for such a pin bench provided with an automatic lifting device.

Les bancs à broches sont généralement équipés de deux rangées de broches disposées sur le chariot porte-broches, le cas échéant en quinconce, et auxquelles correspondent deux rangées d'ailettes. Chacune de ces dernières est pourvue d'un doigt presseur pivotant, muni d'un contre-poids qui, lors de la rotation des ailettes, rabat le doigt presseur correspondant contre le bobinot ou, respectivement, contre la bobine en formation.The spindle benches are generally equipped with two rows of spindles arranged on the spindle carriage, if necessary in staggered rows, and to which correspond two rows of fins. Each of the latter is provided with a pivoting pressing finger, provided with a counterweight which, during the rotation of the fins, folds the corresponding pressing finger against the bobbin or, respectively, against the coil in formation.

Le dispositif de levée automatique se présente principalement sous la forme d'une fourche dont les dents sont introduites, par un mouvement de translation de ladite fourche, entre les bobines disposées sur les broches du chariot porte-broches, parallèlement à l'alignement transversal desdites bobines et broches et ce, après l'abaissement dudit chariot porte-broches et la casse de la mèche. L'extraction desdites bobines consiste alors, d'une part, à les désengager de leurs broches correspondantes par un mouvement vertical de la fourche et, d'autre part, à les retirer dudit chariot porte-broches par un mouvement de translation opposé à celui effectué lors de l'engagement de ladite fourche entre lesdites bobines.The automatic lifting device is mainly in the form of a fork, the teeth of which are introduced, by a translational movement of said fork, between the coils arranged on the pins of the pin-carrying carriage, parallel to the transverse alignment of said coils and spindles after the lowering of said spindle carriage and breaking of the wick. The extraction of said coils then consists, on the one hand, in disengaging them from their corresponding pins by a vertical movement of the fork and, on the other hand, in withdrawing them from said carriage carrying pins by a translational movement opposite to that performed during the engagement of said fork between said coils.

Pour ce faire, lesdites ailettes doivent être arrêtées de telle manière que leurs branches soient disposées perpendiculairement à la direction de translation de ladite fourche.To do this, said fins must be stopped in such a way that their branches are arranged perpendicular to the direction of translation of said fork.

Dans ces conditions, les doigts presseurs des ailettes de la rangée arrière sont situés vers l'arrière et les doigts presseurs des ailettes de la rangée avant sont situés vers l'avant. L'extraction des bobines peut donc être opérée sans risque, les doigts presseurs avant s'ouvrant, c'est-à-dire pivotant vers l'extérieur, lors du passage des bobines. Néanmoins, lors de la mise en place des bobinots vides de remplacement au moyen de la fourche par des mouvements de sens opposé, il est nécessaire que les doigts presseurs des ailettes de la rangée avant soient ouverts afin de ne pas faire obstacle à l'introduction horizontale desdits bobinots.Under these conditions, the pressing fingers of the rear row fins are located towards the rear and the pressing fingers of the front row fins are located towards the front. The extraction of the coils can therefore be carried out without risk, the front pressing fingers opening, that is to say pivoting outwards, during the passage of the coils. However, when placing the empty replacement bobbins by means of the fork in opposite directions, it is necessary that the pressing fingers of the fins of the front row are open so as not to obstruct the introduction horizontal of said coils.

Le but de la présente invention est de garantir l'ouverture des doigts presseurs des ailettes d'un banc à broches pour faciliter la mise en place des bobinots vides par la fourche d'un dispositif de levée automatique.The object of the present invention is to guarantee the opening of the pressing fingers of the fins of a spindle bench to facilitate the positioning of empty bobbins by the fork of an automatic lifting device.

A cet effet, elle a pour objet un dispositif de sécurité pour banc à broches pourvu d'un dispositif de levée automatique, caractérisé en ce qu'il se présente sous la forme de profilés disposés, chacun, sur une des dents d'une fourche du dispositif automatique d'évacuation de bobines pleines et d'amenée de bobinots vides et pourvus d'éléments longitudinaux déformables agissant sur les contre-poids des doigts presseurs des ailettes de la rangée avant lors d'un déplacement de ladite fourche entre lesdites ailettes, de telle manière que les doigts presseurs correspondant sont, respectivement, soit pivotés en position ouverte et maintenus dans cette position, soit rabattus vers l'intérieur des ailettes, suivant le sens de déplacement de ladite fourche.To this end, it relates to a safety device for a bench with spindles provided with an automatic lifting device, characterized in that it is in the form of profiles arranged, each on one of the teeth of a fork of the automatic device for discharging full reels and for supplying empty reels and provided with deformable longitudinal elements acting on the counterweights of the pressing fingers of the fins of the front row when said fork moves between said fins, in such a way that the corresponding pressing fingers are, respectively, either pivoted in the open position and held in this position, or folded inwards of the fins, according to the direction of movement of said fork.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en plan d'une fourche de levée automatique munie du dispositif conforme à l'invention, au début de la phase de mise en place des bobinots vides ;
  • la figure 2 est une vue schématique de détail et en coupe du dispositif représenté à la figure 1, mais relative à une seule ailette, durant la phase de mise en place des bobinots vides ;
  • la figure 3 est une vue schématique analogue à celle de la figure 2, lors du retrait de la fourche, et la figure 4 est une vue en élévation frontale du dispositif représenté partiellement à la figure 2.
The invention will be better understood thanks to the description below, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a plan view of an automatic lifting fork provided with the device according to the invention, at the start of the phase of positioning the empty bobbins;
  • Figure 2 is a schematic detail view in section of the device shown in Figure 1, but relating to a single fin, during the implementation phase of the empty coils;
  • FIG. 3 is a schematic view similar to that of FIG. 2, when the fork is removed, and FIG. 4 is a front elevation view of the device partially shown in FIG. 2.

Conformément à l'invention, et comme le montrent les figures 1 à 4 des dessins annexés, le dispositif de sécurité se présente sous la forme de profilés 1 disposés, chacun, sur une des dents 2 d'une fourche 3 du dispositif automatique d'évacuation de bobines 4 pleines et d'amenée de bobinots 5 vides et pourvus d'éléments longitudinaux 6 déformables agissant sur les contre-poids 7 des doigts presseurs 8 des ailettes 9 de la rangée avant 10 lors d'un déplacement de ladite fourche 3 entre lesdites ailettes 9, de telle manière que les doigts presseurs 8 correspondant sont, respectivement, soit pivotés en position ouverte et maintenus dans cette position, soit rabattus vers l'intérieur des ailettes 9, suivant le sens de déplacement 11 ou 12 de ladite fourche 3.According to the invention, and as shown in Figures 1 to 4 of the accompanying drawings, the safety device is in the form of profiles 1 each arranged on one of the teeth 2 of a fork 3 of the automatic device evacuation of full 4 reels and supply of empty 5 reels provided with deformable longitudinal elements 6 acting on the counterweights 7 of the pressing fingers 8 of the fins 9 of the front row 10 during movement of said fork 3 between said fins 9, such that the corresponding pressing fingers 8 are, respectively, either pivoted in the open position and held in this position, or folded inwards of the fins 9, according to the direction of movement 11 or 12 of said fork 3 .

Ainsi lorsque la fourche 3 s'engage entre les ailettes 9, c'est-à-dire lorsqu'elle se déplace dans le sens indiqué par 11 sur la figure 1, le contrepoids 7 est repoussé vers l'arrière par l'élément longitudinal 6 déformable. Par conséquent, le doigt presseur 8 correspondant est pivoté totalement vers l'extérieur, c'est-à-dire en position ouverte (figure 2), et autorise le passage des bobinots 5 amenés par la fourche 3.Thus when the fork 3 engages between the fins 9, that is to say when it moves in the direction indicated by 11 in Figure 1, the counterweight 7 is pushed backwards by the longitudinal element 6 deformable. Consequently, the corresponding pressing finger 8 is pivoted completely outwards, that is to say in the open position (FIG. 2), and allows the passage of the coils 5 brought by the fork 3.

Par contre, lorsque la fourche 3 se retire, c'est-à-dire lorsqu'elle se déplace dans le sens indiqué par 12 sur la figure 1, le contre-poids 7 est ramené vers l'avant sous l'action de l'élément longitudinal 6 déformable. Ainsi, le doigt presseur 8 est pivoté vers l'intérieur de l'ailette 9 et plaqué contre le velours 13 du bobinot 5 mis en place auparavant (figure 3). L'extrémité de la mèche cassée, disposée sur le doigt presseur 8, est donc accrochée de manière ferme audit velours 13 et le renvidage des nouvelles bobines 4 est alors amorcé dans des conditions optimales.On the other hand, when the fork 3 withdraws, that is to say when it moves in the direction indicated by 12 in FIG. 1, the counterweight 7 is brought forward under the action of the 'deformable longitudinal member 6. Thus, the pressing finger 8 is pivoted towards the inside of the fin 9 and pressed against the velvet 13 of the bobbin 5 previously put in place (FIG. 3). The end of the broken lock, disposed on the pressing finger 8, is therefore hooked firmly to said pile 13 and the winding of the new spools 4 is then started under optimal conditions.

Selon une caractéristique de l'invention, représentée à la figure 1 des dessins annexés, le profilé 1 et l'élément longitudinal 6 déformable ont une longueur correspondant à celle de la course de la fourche 3 entre les ailettes 9, afin que, pendant toute la phase d'introduction des bobinots 5 vides entre les ailettes 9, le maintien des doigts presseurs 8 à l'ouverture soit assuré.According to a characteristic of the invention, shown in Figure 1 of the accompanying drawings, the profile 1 and the deformable longitudinal element 6 have a length corresponding to that of the stroke of the fork 3 between the fins 9, so that during any the introduction phase of the empty bobbins 5 between the fins 9, maintaining the pressing fingers 8 at the opening is ensured.

Conformément à un mode de réalisation préféré de l'invention, et comme le montrent plus particulièrement les figures 2 à 4 des dessins annexés, l'élément longitudinal 6 se présente sous la forme d'une brosse allongée plate, mais cette dernière pourra également comporter une section ronde, ovale ou autre.According to a preferred embodiment of the invention, and as shown more particularly in Figures 2 to 4 of the accompanying drawings, the longitudinal element 6 is in the form of a flat elongated brush, but the latter may also include a round, oval or other section.

Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, l'élément longitudinal 6 déformable se présente sous la forme, soit d'un ruban de velours, soit d'une bande de panne ou encore d'un élément allongé en caoutchouc-mousse.According to an alternative embodiment of the invention, not shown in the accompanying drawings, the deformable longitudinal element 6 is in the form of either a velvet ribbon, a purlin strip or an elongated element made of foam rubber.

Grâce à l'invention, il est donc possible de réaliser un dispositif de sécurité pour un banc à broches pourvu d'un dispositif de levée automatique comportant, notamment, une fourche 3 transporteuse. Ledit dispositif de sécurité permet de garantir une mise en place automatique des bobinots 5 vides sans risque de détériorations des doigts presseurs 8 des ailettes 9 ainsi qu'un plaquage desdits doigts presseurs 8 contre les bobinots 5 mis en place et, par conséquent, un bon accrochage de la mèche cassée sur le velours 13 desdits bobinots 5.Thanks to the invention, it is therefore possible to produce a safety device for a spindle bench provided with an automatic lifting device comprising, in particular, a fork 3 conveyor. Said safety device makes it possible to guarantee an automatic positioning of the empty bobbins 5 without risk of damage to the pressing fingers 8 of the fins 9 as well as a pressing of said pressing fingers 8 against the bobbins 5 put in place and, consequently, a good hooking the broken lock on the velvet 13 of said bobbins 5.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés 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 embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular 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.
