Description

La présente invention a trait aux machines pour la centrifugation des bobines, notamment de fil, à la sortie des traitements par voie humide tels que la teinture, et elle a pour objet un manipulateur agencé de manière à assurer de manière entièrement automatique le chargement et le déchargement du panier tournant d'une ou de plusieurs machines de centrifugation.The present invention relates to machines for centrifuging coils, in particular wire, at the outlet of wet treatments such as dyeing, and it relates to a manipulator arranged so as to ensure fully automatic loading and unloading of the rotating basket from one or more centrifuge machines.

Un tel manipulateur a été décrit dans le document FR-A 2 549 867 qui a trait à une machine à postes multiples pour l'essorage de bobines textiles. Au niveau de chaque essoreuse il est prévu un manipulateur qui est propre d'une part à disposer, sur un plateau mobile renfermé par le panier tournant usuel, chacune des bobines à essorer successivement amenées à l'essoreuse considérée, d'autre part à évacuer dudit plateau chaque bobine après essorage. A cet effet le manipulateur décrit comprend un tiroir agencé à la manière d'un chariot animé d'un mouvement horizontal alternatif qui le fait passer depuis une position reculée jusqu'à une position avancée; à la position reculée, le tiroir, mu vers l'avant, prélève une bobine à partir de la base d'un empilage, pour la repousser le long d'une table fixe qui affleure le débouché supérieur de la cuve de l'essoreuse considérée, et l'amener sur le plateau mobile qui peut s'abaisser pour effectuer le chargement de ladite cuve. En fin d'essorage, ce plateau s'élève pour ramener à la hauteur de la table la bobine essorée qui lors de l'avance du tiroir ou chariot va être repoussée par la bobine à essorer suivante et être expulsée par glissement le long d'un couloir approprié et réception sur un transporteur d'évacuation.Such a manipulator has been described in document FR-A 2 549 867 which relates to a machine with multiple stations for spinning textile rolls. At each wringer is provided a manipulator which is clean on the one hand to have, on a movable plate enclosed by the usual rotating basket, each of the coils to be wrung successively brought to the wringer considered, on the other hand to evacuate of said plate each coil after spinning. For this purpose the manipulator described comprises a drawer arranged in the manner of a carriage driven by an alternating horizontal movement which makes it pass from a retracted position to an advanced position; in the retracted position, the drawer, moved forward, takes a spool from the base of a stack, to push it along a fixed table which is flush with the upper outlet of the wringer tank considered , and bring it on the movable plate which can be lowered to effect the loading of said tank. At the end of spinning, this tray rises to bring back to the table height the spun spool which when advancing the drawer or carriage will be pushed back by the next spool to be spun and be expelled by sliding along an appropriate corridor and reception on an evacuation conveyor.

Cet agencement ne s'est pas révélé avantageux sur le plan pratique. Les bobines se repoussant les unes les autres sous l'effet de poussée du chariot et leur poids à l'état non essoré étant important, le contact entre deux empilages adjacents provoque fréquemment la détérioration du fil qui vient soit s'emmêler à celui de l'empilage adjacent, soit s'accrocher au support de celui-ci. Par ailleurs le débouché des couloirs de glissement doit être placé suffisamment haut au-dessus du transporteur d'évacuation pour permettre le passage des bobines essorées, si bien que la chute engendre le plus souvent une réception à l'état couché.This arrangement has not been found to be advantageous in practical terms. The coils repelling each other under the pushing effect of the carriage and their weight in the non-wrung state being significant, the contact between two adjacent stacks frequently causes the deterioration of the wire which either becomes tangled with that of the 'stacking adjacent, either hang on the support thereof. Furthermore, the opening of the sliding corridors must be placed high enough above the evacuation conveyor to allow the passage of the spun coils, so that the fall most often generates reception in the lying state.

Le manipulateur suivant l'invention est défini à la revendication 1. Il est constitué, à la façon connue, par un chariot qui est animé, par exemple sous l'action d'un vérin à double effet, d'un mouvement horizontal alternatif qui l'amène d'une position reculée de prélèvement jusqu'à une position avancée située au-dessus de l'ouverture du panier tournant de la machine de centrifugation envisagée. Toutefois ce chariot est doté d'un mécanisme de manutention comprenant d'une part deux ailes réglables aptes à former butées pour les bobines successives à essorer, d'autre part deux bras mobiles propres à s'ouvrir pour permettre l'application de chaque bobine contre les ailes précitées, et à se refermer contre ladite bobine en vue de rendre celle-ci solidaire du chariot. Ce dernier comprend en outre un volet articulé associé à un organe d'actionnement destiné à le faire passer d'une orientation horizontale pour laquelle il obture l'ouverture supérieure de la machine de centrifugation, à une position verticale pour laquelle il forme poussoir pour l'évacuation de la bobine extraite du panier tournant de ladite machine.The manipulator according to the invention is defined in claim 1. It is constituted, in known manner, by a carriage which is driven, for example under the action of a double-acting cylinder, of an alternating horizontal movement which brings it from a withdrawn withdrawal position to an advanced position situated above the opening of the rotating basket of the envisaged centrifugation machine. However, this carriage is provided with a handling mechanism comprising on the one hand two adjustable wings capable of forming stops for the successive coils to be wrung, on the other hand two movable arms suitable for opening to allow the application of each coil against the aforementioned wings, and to close against said coil in order to make it integral with the carriage. The latter further comprises an articulated flap associated with an actuating member intended to pass it from a horizontal orientation for which it closes the upper opening of the centrifugation machine, to a vertical position for which it forms a pusher for the evacuation of the coil extracted from the rotating basket of said machine.

D'autres caractéristique remarquables du manipulateur suivant l'invention ressortiront de la description qui va suivre en référence au dessin annexé, lequel dessin, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer:

Other remarkable characteristics of the manipulator according to the invention will emerge from the description which follows with reference to the appended drawing, which drawing, given by way of example, will make it possible to better understand the invention, the characteristics which it presents and the advantages it is likely to provide:

En fig. 1, la référence 1 désigne le bâti général de l'installation formée par la machine de centrifugation 2 et le manipulateur 3 qui assure son alimentation automatique. A la façon connue, notamment par le document FR-A 2 549 867 mentionné ci-dessus, la machine 2 comprend une cuve fixe 4 à l'intérieur de laquelle tourne un panier 5 entraîné en rotation par un moteur électrique 6 porté par une embase 7 du bâti 1; l'arbre 8 de ce moteur 6 est prévu creux de façon à laisser place à un poussoir axial 9 pourvu d'un plateau élévateur 10 qui coulisse librement dans le panier 5 sous l'effet d'un organe d'actionnement, supposé flexible dans l'exemple de réalisation envisagé et guidé à cet effet à l'intérieur d'un coude 11, cet organe, rigide ou flexible, étant commandé alternativement par un vérin pneumatique 12 du type à double effet.In fig. 1, reference 1 designates the general frame of the installation formed by the centrifuge machine 2 and the manipulator 3 which ensures its automatic feeding. In the known way, in particular by the document FR-A 2 549 867 mentioned above, the machine 2 comprises a fixed tank 4 inside which a basket 5 rotates driven by an electric motor 6 carried by a base 7 of frame 1; the shaft 8 of this motor 6 is provided hollow so as to leave room for an axial pusher 9 provided with a lifting plate 10 which slides freely in the basket 5 under the effect of an actuating member, assumed to be flexible in the embodiment envisaged and guided for this purpose inside a bend 11, this member, rigid or flexible, being controlled alternately by a pneumatic cylinder 12 of the double-acting type.

Le manipulateur 3 comprend un chariot 13 pourvu à sa base de patins qui permettent son déplacement sur des guides horizontaux 14 du bâti 1. Le mouvement alternatif du chariot 13 est opéré à l'aide d'un vérin pneumatique 15 à double effet, dont le cylindre est fixé au bâti 1 tandis que l'organe mobile est rendu solidaire dudit chariot par l'intermédiaire d'un bras vertical 16. On observera que le chariot 13 est formé par deux flasques latéraux référencés 13a en fig. 2, réunis l'un à l'autre par une traverse antérieure 13b et une traverse supérieure 13c, de telle sorte que ledit chariot est ouvert vers le bas et vers l'arrière en permettant ainsi à des bobines telles que A (fig. 1), amenées en succession par un tapis transporteur 17, de pénétrer par l'arrière à l'intérieur de ce chariot.The manipulator 3 comprises a carriage 13 provided at its base with pads which allow its movement on horizontal guides 14 of the frame 1. The reciprocating movement of the carriage 13 is effected by means of a double-acting pneumatic cylinder 15, the cylinder is fixed to the frame 1 while the movable member is made integral with said carriage by means of a vertical arm 16. It will be observed that the carriage 13 is formed by two lateral flanges referenced 13a in FIG. 2, joined to each other by a front cross member 13b and an upper cross member 13c, so that said carriage is open downward and backward thereby allowing coils such as A (fig. 1 ), brought in succession by a conveyor belt 17, to penetrate from the rear inside this carriage.

Celui-ci est équipé d'un mécanisme de manutention qui comprend en premier lieu deux axes transversaux 18 (fig. 2) qui sont portés à coulissement par les flasques 13_a de manière à pouvoir être réglés en position axiale à l'aide d'un dispositif denté 19 qui assure le déplacement simultané desdits axes dans des directions opposées; ce dispositif 19 peut notamment être constitué par un pignon central susceptible d'être manoeuvré angulairement à l'aide d'une manivelle ou outil analogue, lequel pignon engrène avec des dentures de crémaillère ménagées sur les extrémités dépassantes des axes 18. Chacun de ceux-ci est solidaire d'une aile transversale 20 profilée de manière à embrasser la paroi cylindrique d'une bobine 1, à la manière qui sera décrite plus loin, et l'on conçoit que le réglage des axes 18 permet de modifier l'écartement mutuel des ailes 20 et l'adaptation de celles-ci au diamètre des bobines à essorer.This is equipped with a handling mechanism which first includes two trans axes side 18 (fig. 2) which are slidably carried by the flanges 13_a so as to be able to be adjusted in axial position using a toothed device 19 which ensures the simultaneous movement of said axes in opposite directions; this device 19 may in particular be constituted by a central pinion capable of being operated angularly using a crank or similar tool, which pinion meshes with rack and pinion teeth formed on the protruding ends of the axes 18. Each of these ci is secured to a transverse wing 20 profiled so as to embrace the cylindrical wall of a coil 1, in the manner which will be described later, and it is understood that the adjustment of the axes 18 makes it possible to modify the mutual spacing wings 20 and the adaptation thereof to the diameter of the coils to be wrung.

Le mécanisme de manutention comprend également deux tiges transversales 21 associées à deux vérins indépendants 22 qui assurent leur coulissement axial dans un sens ou dans l'autre. Chaque tige 21 porte un bras transversal 23 apte, moyennant coulissement de l'un et l'autre desdites tiges en sens inverses, à venir s'appliquer contre la paroi d'une bobine A supposée amenée en butée contre les ailes 20, comme on le décrira plus loin.The handling mechanism also includes two transverse rods 21 associated with two independent cylinders 22 which ensure their axial sliding in one direction or the other. Each rod 21 carries a transverse arm 23 able, by sliding one and the other of said rods in opposite directions, to come to bear against the wall of a coil A supposed brought into abutment against the wings 20, as we will describe it later.

Sur la traverse antérieure 13b du chariot 13 est articulée la base d'un volet basculant 24 attelé à un vérin de manoeuvre 25 du type à double effet. Ce volet 24 est ainsi susceptible d'affecter soit la position relevée à la verticale illustrée en fig. 1, soit la position rabattue à l'horizontale pour laquelle il vient obturer le débouché supérieur de l'ouverture pratiquée dans la table fixe 26 qui entoure le panier tournant 5.On the front cross member 13b of the carriage 13 is articulated the base of a tilting flap 24 coupled to an actuating cylinder 25 of the double-acting type. This flap 24 is thus likely to affect either the position raised vertically illustrated in FIG. 1, that is to say the horizontal folded position for which it closes the upper opening of the opening made in the fixed table 26 which surrounds the rotating basket 5.

On observera enfin que sur la traverse supérieure 13q du chariot 13 est fixé un vérin 27 à axe vertical dont l'organe mobile porte un poussoir 28 dont le rôle sera indiqué plus loin.Finally, it will be observed that on the upper cross member 13 q of the carriage 13 is fixed a jack 27 with a vertical axis whose movable member carries a pusher 28 whose role will be indicated below.

On décrira ci-après le fonctionnement du manipulateur 3 et de la machine de centrifugation 2 en partant du moment où cet ensemble est mis en état de marche.The operation of the manipulator 3 and of the centrifugation machine 2 will be described below, starting from the moment when this assembly is put into working condition.

La prémière bobine A à essorer amenée par le tapis 17 vient s'appliquer contre les ailes 20 préalablement réglées en position. Un palpeur détermine l'arrivée de cette bobine A et actionne les vérins 22, de sorte que les bras 23 viennent enserrer la bobine A qui est alors rendue solidaire du chariot 13. Le vérin 15 entre en action pour repousser le chariot 13 jusqu'à la position avancée illustrée en fig. 3, pour laquelle l'axe du vérin supérieur 27 coincide avec l'axe du panier tournant 5.The first coil A to be wrung brought by the belt 17 is applied against the wings 20 previously adjusted in position. A probe determines the arrival of this coil A and actuates the jacks 22, so that the arms 23 come to grip the coil A which is then made integral with the carriage 13. The jack 15 comes into action to push the carriage 13 to the advanced position illustrated in fig. 3, for which the axis of the upper jack 27 coincides with the axis of the rotating basket 5.

A ce moment, le plateau 10 associé à ce panier 5 se trouve en position haute, de telle sorte que la bobine A serrée entre les bras 23 et les ailes 20 du mé- caniqme de manutention est transférée sur ledit plateau 10 moyennant la simple manoeuvre des vérins 22 à l'écartement.At this time, the plate 10 associated with this basket 5 is in the high position, so that the coil A clamped between the arms 23 and the wings 20 of the handling mechanism is transferred to said plate 10 by simple operation cylinders 22 at the spacing.

Le vérin 12 est ensuite commandé à la contraction afin d'assurer l'abaissement du plateau 10 à l'intérieur du panier 5. Ce mouvement de descente est avantageusement facilité par actionnement du vérin vertical 27 dont le poussoir mobile 28 vient prendre appui contre la partie supérieure de la bobine A qui est ainsi enfoncée à force dans le panier 5 en même temps que le plateau 10 (position de fig. 4).The jack 12 is then controlled by contraction in order to ensure the lowering of the plate 10 inside the basket 5. This lowering movement is advantageously facilitated by actuation of the vertical jack 27 whose movable pusher 28 comes to bear against the upper part of the coil A which is thus forced into the basket 5 at the same time as the plate 10 (position of fig. 4).

Le vérin 27 remonte le poussoir 28 et le chariot 13 est ramené par le vérin 15 à la position reculée de départ. Le vérin 25 abaisse ensuite le volet 24 qui, en s'appliquant contre la table 26, vient obturer la partie supérieure ouverte de la cuve 4, à la manière illustrée en fig. 5. L'essorage de la bobine A peut alors avoir lieu moyennant mise sous tension du moteur 6.The jack 27 rises the pusher 28 and the carriage 13 is returned by the jack 15 to the retracted starting position. The jack 25 then lowers the flap 24 which, by pressing against the table 26, seals the open upper part of the tank 4, in the manner illustrated in FIG. 5. Spinning of coil A can then take place by energizing motor 6.

Dès que l'opération d'essorage est terminée, le volet basculant 24 se relève à la verticale (fig. 6) en même temps que le vérin 12 remonte le plateau 10 avec la bobine A essorée. Le vérin 15 déplace à ce moment le chariot 13 de la position reculée suivant fig. 6 à la position avancée selon fig. 7, si bien que le volet 24 à la position relevée agit à la manière d'un poussoir pour chasser hors du plateau 10 la bobine A essorée. Cette bobine A est recueillie sur un plateau antérieur 29 disposé au niveau de la table 26 et associé à tout dispositif d'évacuation approprié.As soon as the spinning operation is finished, the tilting flap 24 is raised vertically (fig. 6) at the same time as the jack 12 rises the plate 10 with the spool A spun. The jack 15 moves the carriage 13 from the retracted position according to FIG. 6 in the advanced position according to fig. 7, so that the flap 24 in the raised position acts in the manner of a pusher to drive out of the plate 10 the spool A spun. This coil A is collected on a front plate 29 placed at the level of the table 26 and associated with any suitable evacuation device.

Le cycle d'essorage de la bobine A est alors terminé, mais entre temps, c'est-à-dire lorsque le chariot 13 se trouvait à la position reculée suivant fig. 5, une nouvelle bobine à essorer, référencée A', a été amenée par l'arrière par le tapis 17 et est venue se disposer contre les ailes 20. Les bras 23 se sont resserrés sur cette bobine A' qui a été transférée sur le plateau mobile 10 lorsque le chariot 13 est passé de la position reculée de fig. 6 à la position avancée suivant fig. 7. Les cycles d'essorage se succèdent ainsi et il suffit finalement d'assurer l'alimentation du tapis transporteur 17 en bobines à essorer et l'évacuation des bobines essorées à partir du plateau 29.The spin cycle of the coil A is then ended, but in the meantime, that is to say when the carriage 13 was in the retracted position according to FIG. 5, a new coil to be wrung out, referenced A ′, was brought from behind by the belt 17 and came to be disposed against the wings 20. The arms 23 were tightened on this coil A ′ which was transferred to the movable plate 10 when the carriage 13 has passed from the retracted position of FIG. 6 in the advanced position according to fig. 7. The wringing cycles succeed one another in this way and it suffices finally to supply the conveyor belt 17 with coils to be wrung and the evacuation of the coils wrung from the plate 29.

Dans la description qui précède, on a supposé que ce plateau 29 était disposé à la hauteur de la table 26 de façon à recevoir les bobines à la position verticale. Toutefois et en agissant sur des petité vérins de réglage 30 associés au plateau 29, ce dernier peut être disposé à un niveau inférieur de façon à ce que les bobines essorées basculent lorsqu'elles sont repoussées par le volet 24. Fig. 8 illustre une telle variante et fait bien ressortir le fait que les bobines sont recueillies sur le plateau 29 à la position couchée.In the above description, it has been assumed that this plate 29 was arranged at the height of the table 26 so as to receive the coils in the vertical position. However, and by acting on small adjustment cylinders 30 associated with the plate 29, the latter can be arranged at a lower level so that the spun coils tilt when they are pushed back by the flap 24. FIG. 8 illustrates such a variant and clearly highlights the fact that the coils are collected on the plate 29 in the lying position.

On conçoit cependant que le système se bloquerait immédiatement puisque les bobines essorées ne seraient pas repoussées sur le plateau 29 et tomberaient les unes sur les autres. Pour éviter cet inconvénient, on fait comporter au chariot 13 un cadre de poussée 31 (fig. 1 et 2) disposé à l'avant dudit chariot et assemblé à celui-ci de manière articulée afin de pouvoir être manoeuvré angulairement à l'aide d'un vérin tel que 32.It is understood, however, that the system would lock up immediately since the spun coils would not be pushed back onto the plate 29 and would fall on top of each other. To avoid this drawback, the carriage 13 is made to include a thrust frame 31 (FIGS. 1 and 2) disposed at the front of said carriage and assembled to the latter in an articulated manner so as to be able to be maneuvered angularly using '' a cylinder such as 32.

Lorsqu'à la fin de l'opération d'essorage le chariot 13 se déplace d'arrière en avant en repoussant par le volet 24 la bobine A' qui vient d'être essorée, la traverse antérieure 31a du cadre 31, pourvue à cet effet de doigts verticaux 33, repousse la bobine A antérieurement recueillie par le plateau 29, en dégageant de la sorte la partie antérieure dudit plateau qui est alors apte à recevoir à l'état couché la bobine suivante A', comme illustré en fig. 8.When, at the end of the spinning operation, the carriage 13 moves from back to front by pushing the spool A 'which has just been spun through the flap 24, the front cross member 31a of the frame 31, provided with this effect of vertical fingers 33, pushes the coil A previously collected by the plate 29, thereby releasing the front part of said plate which is then able to receive in the lying state the next coil A ', as illustrated in FIG. 8.

Il va de soi que pour permettre à la traverse 31a du cadre de poussée 31 de passer par dessus la bobine A' lorsque le chariot 13 est ramené de la position avancée à la position reculée (voir fig. 4 et 5), le vérin 32 est actionné à la contraction pour relever à l'oblique ledit cadre qui n'est rabaissé qu'une fois le chariot 13 arrivé à sa position reculée. Des entailles 26a (fig. 2) sont ménagées dans le bord antérieur de la table 26 pour permettre aux doigts 33 de venir se disposer aussi près que possible de la cuve 4.It goes without saying that to allow the cross member 31a of the thrust frame 31 to pass over the coil A 'when the carriage 13 is brought back from the advanced position to the retracted position (see FIGS. 4 and 5), the jack 32 is actuated by contraction to raise obliquely said frame which is lowered only once the carriage 13 arrived at its retracted position. Notches 26a (fig. 2) are provided in the front edge of the table 26 to allow the fingers 33 to come to be arranged as close as possible to the tank 4.

Fig. 1 montre que le réglage du plateau récepteur 29 est opéré à l'aide de deux vérins 30 distincts, de façon à permettre de conférer audit plateau une inclinaison appropriée quand les bobines à traiter présentent non pas un profil cylindrique comme on l'a supposé jusqu'ici, mais un profil tronconique. On évite de la sorte tout glissement intempestif des bobines sur le plateau.Fig. 1 shows that the adjustment of the receiving plate 29 is effected by means of two separate jacks 30, so as to make it possible to give said plate an appropriate inclination when the coils to be treated do not have a cylindrical profile as has been assumed up to 'here, but a tapered profile. This avoids any untimely sliding of the coils on the plate.

Il convient d'observer que l'invention se prête particulièrement bien à la réalisation d'installations à essoreuses multiples, du genre de celle illustrée en fig. 9 où l'on a supposé que l'ensemble comportait quatre machines de centrifugation, disposées suivant un même axe orienté transversalement à l'axe de déplacement du chariot 13 du manipulateur 3. Ce chariot 13 est évidemment établi à une largeur idoine ; son mécanisme de manutention comprend, sur les axes 18 et sur les tiges 21, quatre paires d'ailes de butée 20 et quatre paires de bras 23 afin de saisir les quatre bobines à essorer simultanément amenées par le tapis transporteur 17.It should be observed that the invention lends itself particularly well to the production of installations with multiple extractors, of the kind of that illustrated in FIG. 9 where it was assumed that the assembly included four centrifugation machines, arranged along the same axis oriented transversely to the axis of movement of the carriage 13 of the manipulator 3. This carriage 13 is obviously established at a suitable width; its handling mechanism comprises, on the axes 18 and on the rods 21, four pairs of stop wings 20 and four pairs of arms 23 in order to grip the four coils to be wrung simultaneously brought by the conveyor belt 17.

Le manipulateur suivant fig. 8 est équipé d'un cadre de poussée 31 manoeuvré par deux vérins latéraux 32 et l'on a ici supposé que les bobines essorées recueillies à l'état couché sur le plateau récepteur 29 étaient engagées par la traverse 31a sur des tiges-supports 34 orientées horizontalement au-dessus dudit plateau. Il va de soi que le plateau 29 peut être profilé pour recevoir chaque rangée de bobines, notamment en comportant des gouttières en nombre égal à celui des machines de centrifugation.The manipulator according to fig. 8 is equipped with a thrust frame 31 maneuvered by two lateral jacks 32 and it has been assumed here that the spun coils collected in the lying state on the receiving plate 29 were engaged by the cross member 31a on support rods 34 oriented horizontally above said tray. It goes without saying that the plate 29 can be profiled to receive each row of coils, in particular by including gutters in number equal to that of the centrifugation machines.
