Description

La présente invention concerne l'industrie textile, plus particulièrement les bancs à broches pour fibres longues et fibres courtes, et a pour objet un dispositif de levée automatique de bobines sur un banc à broches pour fibres longues et fibres courtes ainsi qu'un procédé mettant en oeuvre ce dispositif.The present invention relates to the textile industry, more particularly the spindle benches for long fibers and short fibers, and has for its object an automatic lifting device for spools on a spindle bench for long fibers and short fibers and a method using implement this device.

Actuellement, l'extraction des bobines pleines des broches d'un banc à broches et leur remplacement par des bobinots vides sont encore, dans la plupart des cas, des opérations réalisées manuellement et requérant des efforts importants de la part des opérateurs chargés de ce travail.Currently, extracting the full bobbins from the spindles of a pin bank and replacing them with empty bobbins are still, in most cases, operations carried out manually and requiring significant efforts on the part of the operators responsible for this work. .

Il existe également différents dispositifs semi-automatiques et automatiques permettant d'accomplir ces opérations. On procède alors, généralement, en premier lieu à l'inclinaison du chariot porte-broches, puis à l'extraction et à l'évacuation des bobines pleines au moyen de dispositifs mécaniques munis de pinces ou de bras manipulateurs, enserrant les bobines pleines dans une zone dégagée des bobinots et, enfin, à la remise en place de bobinots vides sur les broches.There are also various semi-automatic and automatic devices allowing these operations to be carried out. Generally, the tilting carriage is then tilted first, then the full coils are extracted and removed by mechanical devices fitted with grippers or manipulator arms, enclosing the full coils in a clear area of the bobbins and, finally, the replacement of empty bobbins on the pins.

Néanmoins, ces dispositifs connus présentent souvent, d'une part, une précision insuffisante dans leurs manipulations, à l'origine de nombreux dysfonctionnements des bancs à broches correspondants, et entraînent, d'autre part, la non-utilisation de la partie des bobinots nécessaire à la préhension des bobines pleines, d'où il résulte une perte de longueur utile desdits bobinots.However, these known devices often have, on the one hand, insufficient precision in their handling, which is the source of numerous malfunctions of the benches with corresponding pins, and entail, on the other hand, the non-use of the part of the coils necessary for gripping the full reels, which results in a loss of useful length of said reels.

La présente invention a notamment pour but de pallier les inconvénients précités.The present invention aims in particular to overcome the aforementioned drawbacks.

Elle a, en effet, pour objet un dispositif de levée automatique de bobines sur un banc à broches pour fibres longues et fibres courtes, caractérisé en ce qu'il est principalement constitué, d'une part, par une fourche transporteuse, mobile suivant une direction verticale et suivant au moins une direction horizontale parallèle à l'alignement transversal des broches du chariot porte-broches, d'autre part, par des coupelles de support et de manipulation des bobines pleines et des bobinots vides, et, enfin, par un convoyeur d'évacuation des bobines pleines et d'amenée des bobinots vides.It has, in fact, for its object a device for automatically lifting coils on a bench with spindles for long fibers and short fibers, characterized in that it is mainly constituted, on the one hand, by a conveyor fork, movable according to a vertical direction and in at least one horizontal direction parallel to the transverse alignment of the pins of the spindle carriage, on the other hand, by cups for supporting and handling the full bobbins and the empty bobbins, and, finally, by a conveyor for discharging full reels and supplying empty reels.

L'invention a également pour objet un procédé de levée automatique de bobines sur un banc à broches pour fibres longues et fibres courtes mettant en oeuvre le dispositif précité, procédé caractérisé en ce qu'il consiste, après la fin du renvidage des bobines, la casse de la mèche et le dégagement des bobines pleines de leurs ailettes correspondantes, le cas échéant par un abaissement du chariot porte-broches, à extraire lesdites bobines pleines de leurs broches correspondantes et à les transporter vers un convoyeur aérien, au moyen d'une fourche transporteuse coopérant avec des coupelles enfilées sur lesdites broches et supportant, chacune, une bobine, à accrocher lesdites bobines à des porte-bobines vides dudit convoyeur, les coupelles restant solidaires de la fourche, à décrocher ensuite des bobinots vides en nombre égal dudit convoyeur à l'aide desdites coupelles, à les transporter vers les broches libres dudit chariot porte-broches, à les enfiler, ensemble avec les coupelles qui les supportent, sur lesdites broches et, enfin, à dégager ladite fourche transporteuse desdites coupelles enfilées et à l'amener dans une position dégagée de repos.The subject of the invention is also a method of automatically lifting bobbins on a spindle bench for long fibers and short fibers using the above-mentioned device, characterized in that it consists, after the winding of the bobbins has ended, the breakage of the wick and the release of the full coils from their corresponding fins, if necessary by lowering the spindle carriage, to extract said full coils from their corresponding pins and to transport them to an overhead conveyor conveying fork cooperating with cups threaded on said spindles and each supporting a reel, to hang said reels on empty reel holders of said conveyor, the cups remaining integral with the fork, then to unhook empty reels in equal number from said conveyor by means of said cups, to transport them to the free pins of said pin-carrying carriage, to thread them, together ble with the cups which support them, on said pins and, finally, to disengage said conveying fork from said threaded cups and to bring it into a disengaged position of rest.

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 (1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, 1I et 1J) représente, en des vues en élévation frontale et relatives à une seule bobine, les principales étapes du procédé conforme à l'invention ;

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 (1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, 1I and 1J) shows, in front elevation views and relating to a single coil, the main steps of the process according to the invention;
  • FIG. 2 is a plan view of an embodiment of the device according to the invention, represented in the phase of the method corresponding to FIG. 1J, and
  • Figure 3 is a plan view of the device shown in Figure 2, but in the next phase of the process according to the invention.

Conformément à l'invention, et comme le montrent les figures 1 à 3, des dessins annexés, le dispositif de levée automatique de bobines est principalement constitué, d'une part, par une fourche 1 transporteuse, mobile suivant une direction verticale 2 et suivant au moins une direction horizontale 3 parallèle à l'alignement transversal des broches 4 du chariot porte-broches 5, d'autre part, par des coupelles 6 de support et de manipulation des bobines pleines 7 et des bobinots vides 8, et, enfin, par un convoyeur 9 d'évacuation des bobines pleines 7 et d'amenée des bobinots vides 8.In accordance with the invention, and as shown in FIGS. 1 to 3, of the appended drawings, the device for automatically lifting coils mainly consists, on the one hand, of a conveyor fork 1, movable in a vertical direction 2 and following at least one horizontal direction 3 parallel to the transverse alignment of the pins 4 of the pin-carrying carriage 5, on the other hand, by cups 6 for supporting and handling the full coils 7 and the empty coils 8, and, finally, by a conveyor 9 for discharging the full reels 7 and for supplying the empty reels 8.

Selon une première caractéristique de l'invention, représentée notamment aux figures 1F, 1G, 2 et 3, la fourche 1 transporteuse est équipée de patins 10 à ressorts 11 permettant de pincer les bords 12 des coupelles 6, lors de la manipulation des bobines pleines 7 ou des bobinots vides 8 et d'éviter ainsi tout déplacement desdites coupelles 6 par rapport à la fourche 1.According to a first characteristic of the invention, shown in particular in FIGS. 1F, 1G, 2 and 3, the fork 1 conveyor is equipped with pads 10 with springs 11 making it possible to pinch the edges 12 of the cups 6, when handling the full coils 7 or empty bobbins 8 and thus avoid any displacement of said cups 6 relative to the fork 1.

L'utilisation de coupelles 6, enfilées sur les broches 4 et supportant les bobinots 8 durant le renvidage, en combinaison avec la fourche 1 transporteuse, augmente la précision des différentes phases manipulatoires, et facilite, notamment, les opérations de centrage. En outre, lors du renvidage, il est possible d'enrouler la mèche sur toute la hauteur des bobinots 8, la fourche 1 ne manipulant pas directement les bobines pleines 7 et ne nécessitant, par conséquent, aucune zone de préhension dégagée sur lesdits bobinots 8.The use of cups 6, threaded on the spindles 4 and supporting the bobbins 8 during rewinding, in combination with the fork 1 conveyor, increases the precision of the various handling phases, and facilitates, in particular, the centering operations. In addition, during rewinding, it is possible to wind the wick over the entire height of the bobbins 8, the fork 1 not directly handling the full bobbins 7 and therefore requiring no clearing grip area on said bobbins 8 .

Conformément à une première variante de réalisation de l'invention, représentée aux figures 2 et 3 des dessins annexés, la largeur ℓ de la fourche 1 transporteuse correspond à une fraction de la longueur du chariot porte-broches 5, ladite fourche 1 étant également mobile suivant une direction 13 parallèle audit chariot porte-broches 5. La levée automatique peut être réalisée, par exemple, par groupes de huit bobines 8.According to a first embodiment of the invention, shown in Figures 2 and 3 of the accompanying drawings, the width ℓ of the conveyor fork 1 corresponds to a fraction of the length of the spindle carriage 5, said fork 1 also being movable in a direction 13 parallel to said spindle-carrying carriage 5. Automatic lifting can be carried out, for example, in groups of eight coils 8.

Le procédé de levée automatique devra alors être répété autant de fois qu'il y a de sections de huit broches 4 sur le chariot porte-broches 5. Le passage d'une section à l'autre se fera donc par déplacement de la fourche 1 suivant la direction 13.The automatic lifting process will then have to be repeated as many times as there are sections of eight spindles 4 on the spindle-carrying carriage 5. The passage from one section to the other will therefore be done by displacement of the fork 1 following direction 13.

Selon une seconde variante de réalisation de l'invention, non représentée aux dessins annexés, la fourche 1 transporteuse, composée, le cas échéant, de plusieurs segments indépendants, s'étend sur toute la longueur du chariot porte-broches 5. La commande de cette fourche 1 peut, par conséquent, être soit fractionnaire, dans le cas d'une constitution en plusieurs segments, soit générale, dans le cas d'une fourche 1 d'une seule pièce. Il est alors possible d'effectuer la levée de toutes les bobines 7 en une unique opération ; il en résulte une rentabilité accrue du fait d'un arrêt de fonctionnement plus court du banc à broches.According to a second alternative embodiment of the invention, not shown in the accompanying drawings, the conveyor fork 1, composed, where appropriate, of several independent segments, extends over the entire length of the spindle-carrying carriage 5. The control of this fork 1 can, therefore, be either fractional, in the case of a constitution in several segments, or general, in the case of a fork 1 in one piece. It is then possible to carry out the lifting of all the coils 7 in a single operation; this results in increased profitability due to a shorter operating stop of the spindle bench.

Conformément à une autre caractéristique de l'invention, non représentée aux dessins annexés, le dispositif de levée automatique conforme à l'invention comporte, en outre, un dispositif de sécurité activé lors de l'actionnement de la fourche 1 transporteuse et pourvu de moyens avertisseurs sonores et/ou lumineux, ledit dispositif permettant, en outre, le cas échéant, de délimiter une zone de sécurité autour du banc à broches considéré.According to another characteristic of the invention, not shown in the accompanying drawings, the automatic lifting device according to the invention further comprises a safety device activated when the fork 1 conveyor is actuated and provided with means audible and / or light alarms, said device also making it possible, if necessary, to delimit a safety zone around the bench with pins in question.

L'invention a également pour objet un procédé de levée automatique de bobines 7 mettant en oeuvre le dispositif décrit ci-dessus, procédé consistant, après la fin du renvidage des bobines 7, la casse de la mèche et le dégagement des bobines 7 pleines de leurs ailettes 14 correspondantes, le cas échéant par un abaissement du chariot porte-broches 5 (figure 1A), à extraire lesdites bobines 7 pleines de leurs broches 4 correspondantes (figure 1B) et à les transporter vers un convoyeur 9 aérien (figure 1D), au moyen d'une fourche 1 transporteuse coopérant avec des coupelles 6 enfilées sur lesdites broches 4 et supportant, chacune, une bobine 7, à accrocher lesdites bobines 7 à des porte-bobines 15 vides dudit convoyeur 9 (figures 1E et 1F), les coupelles 6 restant solidaires de la fourche 1, à décrocher ensuite des bobinots 8 vides en nombre égal dudit convoyeur 9 à l'aide desdites coupelles 6 (figures 1G, 1H et 1I), à les transporter vers les broches 4 libres dudit chariot porte-broches 5, à les enfiler, ensemble avec les coupelles 6 qui les supportent, sur lesdites broches 4 (figures 1J et 2) et, enfin, à dégager ladite fourche 1 transporteuse desdites coupelles 6 enfilées (figure 3) et à l'amener dans une position dégagée de repos.The subject of the invention is also a method of automatic lifting of spools 7 using the device described above, a method consisting, after the winding of the spools 7 has ended, breaking the wick and disengaging the spools 7 full of their corresponding fins 14, if necessary by lowering the pin-carrying carriage 5 (FIG. 1A), extracting said coils 7 full of their corresponding pins 4 (FIG. 1B) and transporting them to an overhead conveyor 9 (FIG. 1D) , by means of a conveyor fork 1 cooperating with cups 6 threaded on said pins 4 and each supporting a coil 7, to hook said coils 7 to empty coil carriers 15 of said conveyor 9 (FIGS. 1E and 1F), the cups 6 remaining integral with the fork 1, then unhooking bobbins 8 empty in equal number from said conveyor 9 using said cups 6 (Figures 1G, 1H and 1I), to transport them to the free pins 4 of said spindle carriage 5, to put them on, together with the cups 6 which support them, on said pins 4 (Figures 1J and 2) and, finally, to release said fork 1 conveying said threaded cups 6 (Figure 3) and '' bring it into a clear position of rest.

Lors de la remontée du chariot porte-broches 5, un déplacement de celui-ci au-delà de sa position normale, lors du fonctionnement du banc à broches, permettra d'enfoncer à fond les bobinots 8 sur les broches 4 grâce à des butées 17 disposées sur les ailettes 14.During the ascent of the spindle carriage 5, a displacement of the latter beyond its normal position, during the operation of the spindle bench, will make it possible to push the coils 8 fully onto the pins 4 by means of stops 17 arranged on the fins 14.

Selon une caractéristique supplémentaire de l'invention, et comme le montrent notamment les figures 1A et 1B des dessins annexés, l'extraction des bobines 7 pleines de leurs broches 4 consiste, tout d'abord, à amener la fourche 1, à partir de sa position de repos, en face du chariot porte-broches 5 et à hauteur des coupelles 6, puis à introduire ladite fourche 1 entre les broches 4 par un mouvement de translation horizontal, de manière à engager les coupelles 6 entre les patins 10 à ressort 11 et les glissières 16 correspondantes et, enfin, à désenfiler les ensembles coupelles 6 - bobines 7 de leurs broches 4 correspondantes par un mouvement vertical de ladite fourche 1.According to an additional characteristic of the invention, and as shown in particular in FIGS. 1A and 1B of the appended drawings, the extraction of the coils 7 full of their pins 4 consists, first of all, in bringing the fork 1, from its rest position, opposite the pin-carrying carriage 5 and at the height of the cups 6, then introducing said fork 1 between the pins 4 by a horizontal translational movement, so as to engage the cups 6 between the pads 10 with spring 11 and the corresponding slides 16 and, finally, to thread the cup assemblies 6 - coils 7 of their corresponding pins 4 by a vertical movement of said fork 1.

Le déplacement des doigts presseurs 18 des ailettes 14 dans une position écartée lors de l'extraction des bobines 7 (figures 1B et 1C), autorisera, ultérieurement, la mise en place des bobinots 8 (figures 1J et 2) sans risque d'endommagement desdits doigts presseurs 18.The displacement of the pressing fingers 18 of the fins 14 in a separated position during the extraction of the coils 7 (FIGS. 1B and 1C), will subsequently authorize the positioning of the coils 8 (FIGS. 1J and 2) without risk of damage. said pressing fingers 18.

Cette mise en place des bobinots 8, vers les broches 4 consiste à effectuer, au moyen de la fourche 1, les mouvements inverses de ceux décrits ci-dessus pour l'extraction des bobines 7, et ce dans un ordre inverse.This positioning of the coils 8, towards the pins 4 consists in carrying out, by means of the fork 1, the reverse movements of those described above for the extraction of the coils 7, and this in reverse order.

Comme le montrent les figures 1D à 1I, les opérations d'accrochage des bobines 7 pleines et de décrochage des bobinots 8 vides sont réalisées par des mouvements verticaux de la fourche 1, la disposition des porte-bobines 15 sur le convoyeur aérien 9 correspondant à la disposition des broches 4 sur le chariot porte-broches 5. En outre, entre les phases représentées aux figures 1F et 1G, le convoyeur 9 se déplace d'une longueur telle qu'il présente en face des coupelles 6 vides, un nombre égal de bobinots 8 vides.As shown in FIGS. 1D to 1I, the operations for hooking up the full reels 7 and for removing the empty reels 8 are carried out by vertical movements of the fork 1, the arrangement of the reel carriers 15 on the overhead conveyor 9 corresponding to the arrangement of the spindles 4 on the spindle-carrying carriage 5. In addition, between the phases shown in FIGS. 1F and 1G, the conveyor 9 moves with a length such that it has opposite the 6 empty cups, an equal number of 8 empty bobbins.

L'actionnement de la fourche 1 peut être réalisé, par exemple, par des moyens mécaniques commandés par des dispositifs électriques, hydrauliques ou pneumatiques et contrôlés, le cas échéant, par un automate programmable.The actuation of the fork 1 can be achieved, for example, by mechanical means controlled by electrical, hydraulic or pneumatic devices and controlled, if necessary, by a programmable controller.

Les patins 10 pourront également, selon une variante de réalisation, être actionnés par des moyens pneumatiques ou hydrauliques.The pads 10 may also, according to an alternative embodiment, be actuated by pneumatic or hydraulic means.

Grâce à l'invention, il est, par conséquent, possible de procéder à la levée automatique de l'ensemble ou d'une partie des bobines 7 d'un banc à broches 4 et à leur remplacement par des bobinots 8 par l'intermédiaire d'une fourche 1 coopérant avec des coupelles 6 de support et de manipulation des bobines 7 et des bobinots 8, permettant d'opérer avec une grande précision de mouvement et sans manipuler directement lesdites bobines 7 ou lesdits bobinots 8.Thanks to the invention, it is therefore possible to carry out the automatic lifting of all or part of the coils 7 of a spindle bench 4 and their replacement by coils 8 via a fork 1 cooperating with cups 6 for supporting and handling the coils 7 and the coils 8, making it possible to operate with high precision of movement and without directly handling said coils 7 or said coils 8.

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.
