Abstract

The invention relates to method and device for the orientable mounting of a circular part, such as a joint (10), on a suspension arm or A-arm of a motor vehicle. The joint (10) comprises two ribs extending diametrically to and opposite one another. The mounting device comprises a translatably movable element (36) provided with a notch for receiving the joint and an optical sensor (42) for detecting the presence of one of the ribs in a beam. The joint (10) is moved in the axis of the movable head (24) by the movable element (36). When the sensor detects the presence of a rib, the head rotates prior to descending toward the joint, such that the lugs (30) thereof do not collide with the ribs. Said ribs can then rotate the joint in order to orient same.

Description

MONTAGE AVEC ORIENTATION D'UNE ARTICULATION ELASTIQUE SUR UN BRAS DE SUSPENSION DE VEHICULE AUTOMOBILE  ASSEMBLY WITH ORIENTATION OF AN ELASTIC ARTICULATION ON A SUSPENSION ARM OF A MOTOR VEHICLE
L'invention a trait au domaine de l'assemblage par emmanchement d'une pièce généralement circulaire sur un support tel qu'un composant de suspension de véhicule automobile. Plus précisément, l'invention a trait au montage d'articulations élastiques sur un bras ou triangle de suspension d'un véhicule automobile. L'invention a trait à un procédé ainsi qu'à un dispositif de montage d'une pièce telle qu'une articulation élastique sur un support tel qu'un bras de suspension. The invention relates to the field of assembly by fitting a generally circular piece on a support such as a motor vehicle suspension component. More specifically, the invention relates to the assembly of elastic joints on an arm or wishbone of a motor vehicle. The invention relates to a method and to a device for mounting a part such as an elastic articulation on a support such as a suspension arm.
Le document de brevet FR 2 769 060 A1 divulgue une articulation élastique pour train roulant de véhicule automobile. L'articulation de cet enseignement, bien que d'apparence symétrique en révolution, présente en son sein une dissymétrie qui impose un montage suivant une orientation particulière sur le triangle de suspension. En effet, le tube central comprend deux tenons de section généralement circulaire diamétralement opposés suivant une direction transversale au tube et reçus dans deux demi-bagues faisant office de palier. Le tube peut ainsi pivoter autour de l'axe des tenons. Deux nervures de matière élastomère sont prévues entre le tube et la bague extérieure, les nervures s'étendant circulairement entre les tenons. L'articulation est ainsi prévue pour être montée sur un triangle de suspension en vue d'assurer la liaison de deux sommets du triangle à la structure du véhicule. Chacune de ces deux articulations doit alors être orientée de manière à ce que l'axe des tenons soit aligné avec l'axe longitudinal du véhicule, de manière à assurer une capacité et stabilité de pivotement optimale. Cet enseignement manque de s'intéresser au montage des articulations sur le triangle de suspension et plus particulièrement au problème d'orientation des articulations. Les articulations sont en effet habituellement montées par emmanchement ou encore par pressage dans un logement correspondant d'un bras ou triangle de suspension. Dans une logique d'automatisation d'assemblage, il est utile que l'orientation des articulations puisse être assurée de manière automatique. Patent document FR 2 769 060 A1 discloses an elastic articulation for a motor vehicle running gear. The articulation of this teaching, although apparently symmetrical in revolution, presents within it an asymmetry which imposes a mounting in a particular orientation on the triangle of suspension. Indeed, the central tube comprises two pins of generally circular section diametrically opposed in a direction transverse to the tube and received in two bearing half-rings. The tube can thus pivot about the axis of the tenons. Two ribs of elastomeric material are provided between the tube and the outer ring, the ribs extending circularly between the tenons. The joint is thus provided to be mounted on a suspension triangle to ensure the connection of two vertices of the triangle to the vehicle structure. Each of these two joints must then be oriented so that the pin axis is aligned with the longitudinal axis of the vehicle, so as to ensure optimum capacity and pivot stability. This teaching lacks interest in assembling the joints on the wishbone and more particularly the problem of orientation of the joints. The joints are in fact usually mounted by fitting or by pressing into a corresponding housing of an arm or wishbone. In a logic of assembly automation, it is useful that the orientation of the joints can be ensured automatically.
Le document de brevet FR 1 302 533 divulgue un procédé automatisé de positionnement angulaire de pièces circulaires telles que des viroles cylindriques de roues de véhicules. Ces viroles comprennent, chacune, une discontinuité sur leur périphérie, telle que par exemple un ressaut, une fente ou encore une soudure à la jonction entre deux bords adjacents. Le procédé détrompeur consiste à recevoir une virole depuis une goulotte d'amenée de viroles en série. Un balancier de distribution permet de déplacer une virole à la fois vers une zone de réception formée par deux rouleaux fous. Un bras rotatif autour de la virole ainsi positionnée comprend une languette apte à coopérer avec le rebord sus mentionné. Le bras effectue alors un tour complet afin d'être sûr qu'il coopère par engagement avec le rebord et positionne angulairement la virole de manière constante. Cette solution est intéressante et relativement simple à mettre en œuvre. Elle requiert cependant la présence d'un rebord ou surface d'accrochage à la périphérie de l'élément circulaire à orienter. De plus, elle prévoit un positionnement vertical de l'élément à orienter, c'est-à-dire avec son axe de rotation ou de symétrie à l'horizontale. Or, dans le cas d'assemblage d'articulations élastiques de train roulant, ceux-ci sont habituellement disposés à l'horizontale de manière à pouvoir être pris et monté en force par une de leurs faces latérales. L'invention a pour objectif de proposer une solution au problème d'orientation angulaire d'éléments circulaires, tels que des articulations élastiques, lors de leur montage sur un support tel qu'un bras de suspension. Patent document FR 1 302 533 discloses an automated method of angular positioning of circular parts such as cylindrical ferrules of vehicle wheels. These ferrules each comprise a discontinuity on their periphery, such as for example a projection, a slot or a weld at the junction between two adjacent edges. The keying method consists in receiving a ferrule from a chute for supplying ferrules in series. A distribution beam enables one ring to be moved at a time to a reception zone formed by two idle rollers. A rotating arm around the ferrule thus positioned comprises a tongue adapted to cooperate with the aforementioned flange. The arm then performs a complete turn to be sure that it cooperates by engagement with the rim and angularly positions the ferrule steadily. This solution is interesting and relatively simple to implement. However, it requires the presence of a rim or attachment surface at the periphery of the circular element to be oriented. In addition, it provides a vertical positioning of the element to be oriented, that is to say with its axis of rotation or symmetry horizontally. However, in the case of assembly of elastic articulations of undercarriage, they are usually arranged horizontally so that it can be caught and force-fitted by one of their lateral faces. The object of the invention is to propose a solution to the problem of angular orientation of circular elements, such as elastic joints, when they are mounted on a support such as a suspension arm.

The detecting step of the polarizing surface preferably takes place before the step of positioning the piece in front of a moving head.
Les étapes de préhension de la pièce et de mise en place de la pièce sur le support sont préférentiellement menées au moyen de la tête mobile. Le mouvement de rotation de la tête à l'étape de déplacement de la tête mobile vers la pièce a préférentiellement lieu avant un mouvement de translation de la tête mobile vers la pièce. The steps of gripping the workpiece and placing the workpiece on the support are preferably carried out by means of the movable head. The rotational movement of the head at the step of moving the movable head towards the workpiece preferably takes place before a translational movement of the movable head towards the workpiece.

La tête mobile comprend préférentiellement trois positions angulaires prédéfinies : une première position correspondant à la position initiale au début d'un cycle de montage, une deuxième position intermédiaire correspondant à la position prise suite à la détection d'une position angulaire de la pièce où les moyens d'engagement en rotation de la tête mobile dans la première position sont susceptibles d'entrer en collision avec la ou une des surfaces détrompeur, et une troisième position correspondant à la position d'orientation finale. La deuxième position est préférentiellement située angulairement entre les première et troisième positions, c'est-à-dire que la tête allant de la première à la troisième position passe par la deuxième position. La deuxième position peut correspondre à une rotation de 90° par rapport à la première position et la troisième position peut correspondre à une rotation de 180° par rapport à la première position, cette rotation étant dans le même sens que la rotation de la première à la deuxième position. The engagement means of the movable head are preferably generally aligned with the direction of detection of the presence of the polarizing surface. The movable head preferably comprises three predefined angular positions: a first position corresponding to the initial position at the beginning of a mounting cycle, a second intermediate position corresponding to the position taken following the detection of an angular position of the part where the rotational engagement means of the movable head in the first position are capable of colliding with the one or more of the polarizing surfaces, and a third position corresponding to the final orientation position. The second position is preferably located angularly between the first and third positions, that is to say that the head from the first to the third position passes through the second position. The second position may correspond to a rotation of 90 ° with respect to the first position and the third position may correspond to a rotation of 180 ° with respect to the first position, this rotation being in the same direction as the rotation of the first position. the second position.
Selon un mode avantageux de l'invention, la pièce comprend sur au moins une de ses faces deux nervures diamétrales et opposées formant des surfaces détrompeurs.

Les caractéristiques optionnelles de l'invention qui sont énoncées pour le procédé de montage et le dispositif de montage, respectivement, sont également valables pour l'autre du procédé et du dispositif étant donné que le procédé et le dispositif concernent la même invention. Les mesures de l'invention sont avantageuses notamment en ce qu'elles permettent le montage des pièces sur leur support à une cadence plus élevée. En effet, la détection de positions angulaires défavorables avec la position initiale de la tête permet de commander la rotation de la tête avant son approche de l'articulation, afin d'éviter toute collision entre les moyens d'engagement et la ou les surfaces détrompeur. Ces mesures évitent également une étape spécifique ou séparées d'orientation des articulations, une telle étape étant potentiellement coûteuse en temps et/ou en moyens techniques. Les moyens de détection de l'orientation des articulations sont particulièrement intéressants car économiques. De plus, ils n'entrent pas en contact avec les articulations et ne perturbent en rien leur déplacement. Les moyens prévus pour l'amenée en translation de l'articulation vers la zone de réception sont particulièrement intéressants : ils sont en effet simples à mettre en œuvre. Ils permettent l'usage d'un rail vibrant comme alimentation, ce qui est assez simple et commode. Ils permettent également de déplacer l'articulation sans la faire tourner et, de plus, de détecter son orientation avant son transfert vers la tête mobile. D'autres caractéristiques et avantages de la présente invention seront mieux compris à l'aide de la description et des dessins parmi lesquels : The optional features of the invention that are set forth for the mounting method and the mounting device, respectively, are equally valid for the other of the method and the device since the method and apparatus relate to the same invention. The measures of the invention are advantageous in particular that they allow the mounting of the parts on their support at a higher rate. Indeed, the detection of unfavorable angular positions with the initial position of the head makes it possible to control the rotation of the head before approaching the articulation, in order to avoid any collision between the engagement means and the polarizing surface (s). . These measures also avoid a specific step or separate orientation of the joints, such a step being potentially costly in time and / or technical means. The means for detecting the orientation of the joints are particularly interesting because economic. In addition, they do not come into contact with the joints and do not disturb their movement. The means provided for translational translation of the joint to the receiving zone are particularly interesting: they are indeed simple to implement. They allow the use of a vibrating rail as a power supply, which is quite simple and convenient. They also make it possible to move the articulation without rotating it and, moreover, to detect its orientation before it is transferred to the moving head. Other features and advantages of the present invention will be better understood from the description and the drawings, among which:

La figure 1 illustre de manière schématique la partie gauche d'un train roulant avant 2 d'un véhicule automobile. Il comprend essentiellement un triangle de suspension 4 reliant une roue 6 à une structure 12 du véhicule. La liaison entre le triangle 4 et la roue 6 se fait via une rotule 8 et la liaison entre le triangle 4 et la structure 12 a lieu via deux articulations élastiques 10. Ces articulations sont représentées de manière schématique. Bien que généralement circulaires et en apparence symétriques en révolution, elles présentent une dissymétrie liée à leur fonction de pivotement essentiellement selon la direction longitudinale du véhicule. Figure 1 schematically illustrates the left side of a front undercarriage 2 of a motor vehicle. It essentially comprises a suspension triangle 4 connecting a wheel 6 to a structure 12 of the vehicle. The connection between the triangle 4 and the wheel 6 is via a ball 8 and the connection between the triangle 4 and the structure 12 takes place via two elastic joints 10. These joints are shown schematically. Although generally circular and apparently symmetrical in revolution, they have an asymmetry related to their pivoting function essentially in the longitudinal direction of the vehicle.
La figure 2 illustre en perspective une articulation 10 du train roulant de la figure 1 . Elle comprend essentiellement une bague extérieure 14, un tube intérieur 16 destiné à recevoir un moyen de fixation du type vis, et de la matière élastomère entre le tube 16 et la bague extérieure 14. La matière élastomère et/ou le tube peuvent présenter des particularités non visibles à la figure 2, destinées notamment à favoriser la fonction de pivotement suivant une direction transversale donnée. La matière élastomère présente deux nervures 18 sur chaque face latérale de l'articulation 10. Ces nervures 18 sont diamétralement opposées et constituent un repère d'orientation de l'articulation. Il est à noter que des articulations élastiques présentant une orientation sont bien connues en soi de l'homme de métier. Il n'est pas nécessaire de préciser davantage les détails de construction de telles articulations. FIG. 2 illustrates in perspective a hinge 10 of the undercarriage of FIG. 1. It essentially comprises an outer ring 14, an inner tube 16 intended to receive a fastening means of the screw type, and of the elastomeric material between the tube 16 and the outer ring 14. The elastomeric material and / or the tube may have features not visible in Figure 2, intended in particular to promote the pivot function in a given transverse direction. The elastomeric material has two ribs 18 on each lateral face of the articulation 10. These ribs 18 are diametrically opposed and constitute a reference mark of the articulation. It should be noted that elastic joints having an orientation are well known to those skilled in the art. It is not necessary to further specify the construction details of such joints.
La figure 3 est une vue en plan d'un dispositif de montage d'articulations élastiques sur un support tel qu'un bras de suspension, le dispositif étant conforme à l'invention. La figure 4 est une vue en élévation du dispositif de la figure 3. Le dispositif 20 comprend essentiellement un bâti 22 supportant une tête mobile de montage 24. Cette tête est mobile en translation par un dispositif à vérin pneumatique ou hydraulique 28. Elle est également mobile en rotation par un orienteur 26. Ce dernier peut être un dispositif à piston rotatif du type palette apte à prendre différentes positions angulaires. Ce type de dispositif est bien connu en soi de l'homme de métier. La tête mobile 24 est généralement circulaire et comprend sur sa face frontale deux doigts 30 s'étendant généralement parallèlement à son axe de translation, ces doigts étant diamétralement opposés par rapport à cet axe. Leur fonction sera détaillée plus loin. Figure 3 is a plan view of a device for mounting elastic hinges on a support such as a suspension arm, the device being in accordance with the invention. FIG. 4 is an elevational view of the device of FIG. 3. The device 20 essentially comprises a frame 22 supporting a movable mounting head 24. This head is movable in translation by a device with a pneumatic or hydraulic jack 28. It is also movable in rotation by an orientator 26. The latter may be a rotary piston device type pallet able to take different angular positions. This type of device is well known in itself to those skilled in the art. The movable head 24 is generally circular and comprises on its front face two fingers 30 extending generally parallel to its axis of translation, these fingers being diametrically opposite with respect to this axis. Their function will be detailed later.
Le dispositif 20 comprend également un support 32 pour l'articulation 10 lors des opérations de positionnement angulaire et de préhension qui vont être décrites plus loin. Le support 32 comprend un téton 34 destiné à pénétrer le tube de l'articulation en vue de son centrage et de son positionnement. Le support 32 peut être mobile en translation suivant l'axe de déplacement de la tête mobile 30. The device 20 also comprises a support 32 for the articulation 10 during the angular positioning and gripping operations which will be described later. The support 32 comprises a pin 34 intended to penetrate the tube of the joint with a view to its centering and positioning. The support 32 may be movable in translation along the axis of displacement of the movable head 30.
Le dispositif 20 comprend également latéralement des moyens d'amenée automatique des articulations, une par une, vers le support 32. Ces moyens comprennent un élément 36 s'étendant transversalement et mobile en translation via un vérin pneumatique 38. Cet élément comprend une encoche 46 en forme généralement de U dont la largeur correspond essentiellement à celle des articulations 10. Un rail vibrant 48 d'amenée des articulations est disposé en face de l'encoche 46 de l'élément mobile en translation 36. Le rail 48 est dimensionné pour amener les articulations les unes dernières les autres, c'est-à-dire disposées en série. The device 20 also laterally comprises means for automatically feeding the joints, one by one, towards the support 32. These means comprise a member 36 extending transversely and movable in translation via a pneumatic cylinder 38. This element comprises a notch 46 generally U-shaped whose width corresponds essentially to that of the joints 10. A vibrating rail 48 for supplying the articulations is disposed facing the notch 46 of the movable member in translation 36. The rail 48 is sized to bring the joints one last the other, that is to say arranged in series.
Dès qu'une articulation 10 pénètre l'encoche 46, l'élément mobile 36 peut alors être déplacé vers la zone de réception de l'articulation au niveau de l'axe vertical du support 32 et de la tête mobile 24. La présence de l'articulation 10 dans l'encoche 46 est détectée par des moyens de détection de présence, ces moyens étant optoélectroniques à faisceau traversant 44. Ces derniers sont disposés sur un support 40 en forme de U et fixés à l'élément mobile 36, la forme de U du support chevauchant le fond de l'encoche 46. Le faisceau généré par ces moyens de détection de présence 44 est généralement horizontal et à hauteur de la bague extérieure de l'articulation lorsqu'elle est disposée dans le fond de l'encoche 46. Dès qu'une articulation est logée dans l'encoche 46, le faisceau de ces moyens 44 est interrompu par la bague extérieure. As soon as a hinge 10 penetrates the notch 46, the mobile element 36 can then be moved towards the hinge receiving zone at the vertical axis of the support 32 and the movable head 24. The presence of the hinge 10 in the notch 46 is detected by means of presence detection, these means being optoelectronic through beam 44. These are arranged on a support 40 in the shape of a U and fixed to the movable element 36, the U-shaped support overlapping the bottom of the notch 46. The beam generated by these presence detection means 44 is generally horizontal and at the height of the outer ring of the hinge when disposed in the bottom of the notch 46. As soon as a hinge is housed in the notch 46, the bundle of these means 44 is interrupted by the outer ring.
L'élément mobile 36 comprend également des moyens de détection 42 de l'orientation de l'articulation, ces moyens étant également optoélectroniques à faisceau traversant, similaires aux moyens de détection de présence 44. Ils sont cependant disposés un peu plus haut sur le support 40 ainsi qu'un peu plus vers l'axe central de l'articulation lorsqu'elle est en place dans l'encoche 46, de manière à ce que le faisceau soit interrompu par une des deux nervures 18 (voir figure 2) diamétralement opposées, lorsqu'une d'elles est orientée vers le fond de l'encoche 46. Dans la représentation de la figure 4, le faisceau optique des deuxièmes moyens de détection 42 n'est pas interrompu, les nervures 18 étant orientées essentiellement parallèlement au faisceau. Le faisceau passe donc au-dessus de la bague extérieure de l'articulation et latéralement au tube intérieur. Le principe de fonctionnement du dispositif des figures 3 et 4 va être décrit en relation avec les figures 5 et 6. The movable element 36 also comprises means 42 for detecting the orientation of the articulation, these means being also optoelectronic beam-beam, similar to the presence detection means 44. However, they are arranged a little higher on the support 40 and a little more towards the central axis of the articulation when it is in place in the notch 46, so that the beam is interrupted by one of the two ribs 18 (see Figure 2) diametrically opposed when one of them is oriented towards the bottom of the notch 46. In the representation of FIG. 4, the optical beam of the second detection means 42 is not interrupted, the ribs 18 being oriented substantially parallel to the beam . The beam thus passes over the outer ring of the joint and laterally to the inner tube. The operating principle of the device of FIGS. 3 and 4 will be described in relation with FIGS. 5 and 6.
La figure 5 illustre trois orientations possibles de l'articulation 10 où le faisceau des moyens de détection de l'orientation 42 n'est pas interrompu, cette absence de détection correspondant à un premier mode de fonctionnement de la tête mobile du dispositif. En effet, dans cette plage de positionnement angulaire de l'articulation, les doigts 30 de la tête mobile 24 (voir figure 3) qui sont initialement alignés avec une direction parallèle au faisceau des moyens de détection 42, ne peuvent être descendus avec la tête sans qu'ils entrent en collision avec au moins une des nervures 18. En l'absence d'interruption du faisceau du détecteur optoélectronique 42, la tête mobile 24 (figure 3) est alors déplacée en rotation d'un angle de 90° de manière à ce que ses doigts 30 soient alignés avec une direction perpendiculaire à celle du faisceau. Cette position des doigts est visible aux trois représentations de la figure 5. La tête mobile peut ainsi être descendue vers l'articulation jusqu'à ce que l'extrémité des doigts 30 soit à hauteur des nervures. La tête mobile subit alors un deuxième mouvement de rotation de 90° supplémentaire, c'est-à-dire dans le même sens que le premier mouvement, de manière à ce que les doigts viennent en contact avec les faces latérales correspondantes des nervures et puissent entraîner l'articulation en rotation en vue de la positionner angulairement. FIG. 5 illustrates three possible orientations of the articulation 10 where the beam of the orientation detection means 42 is not interrupted, this lack of detection corresponding to a first mode of operation of the mobile head of the device. Indeed, in this range of angular positioning of the joint, the fingers 30 of the movable head 24 (see FIG. 3) which are initially aligned with a direction parallel to the beam of the detection means 42, can not be descended with the head without colliding with at least one of the ribs 18. In the absence of interruption of the beam of the optoelectronic detector 42, the moving head 24 (FIG. 3) is then displaced in rotation by an angle 90 ° so that his fingers 30 are aligned with a direction perpendicular to that of the beam. This position of the fingers is visible in the three representations of Figure 5. The movable head can be lowered to the joint until the end of the fingers 30 is at the height of the ribs. The movable head then undergoes a second rotational movement of 90 ° further, that is to say in the same direction as the first movement, so that the fingers come into contact with the corresponding lateral faces of the ribs and can rotate the articulation in order to position it angularly.
Similairement à la figure 5, la figure 6 illustre trois orientations possibles de l'articulation où cette fois le faisceau des moyens de détection est interrompu, correspondant à une détection et à un deuxième mode de fonctionnement du dispositif. Dans les positions angulaires de l'articulation représentées à la figure 6, les doigts 30 de la tête mobile 24 (figure 3) qui sont initialement alignés avec une direction parallèle au faisceau des moyens de détection 42, peuvent être descendus avec la tête sans qu'ils entrent en contact avec les nervures 18. Une fois la tête descendue jusqu'à ce que l'extrémité des doigts 30 soit à hauteur des nervures 18, la tête subit alors une rotation de 180° dans le même sens que les deux rotations de 90° du premier mode de fonctionnement décrit ci-avant en relation avec la figure 5, de manière à ce que les doigts viennent en contact avec les nervures et puissent entraîner l'articulation en rotation en vue de la positionner angulairement identiquement au premier mode de fonctionnement. Une fois l'articulation positionnée angulairement, suivant les premier ou deuxième modes qui viennent d'être décrits, celle-ci peut alors être prise par la tête en vue de son emmanchement dans un orifice correspondant du triangle de suspension. Ces étapes de prise de l'articulation et d'emmanchement sont bien connues en soi de l'homme de métier. Similarly to Figure 5, Figure 6 illustrates three possible orientations of the joint where this time the beam of the detection means is interrupted, corresponding to a detection and a second mode of operation of the device. In the angular positions of the joint shown in FIG. 6, the fingers 30 of the movable head 24 (FIG. 3), which are initially aligned with a direction parallel to the beam of the detection means 42, can be lowered with the head they come into contact with the ribs 18. Once the head is lowered until the end of the fingers 30 is at the height of the ribs 18, the head is then rotated 180 ° in the same direction as the two rotations. 90 ° of the first operating mode described above in relation to Figure 5, so that the fingers come into contact with the ribs and can cause the articulation in rotation to angularly position it identically to the first mode Operating. Once the articulation angularly positioned, according to the first or second modes that have just been described, it can then be taken by the head for fitting into a corresponding hole of the suspension triangle. These steps of taking the joint and fitting are well known to those skilled in the art.
La détection de positions angulaires de l'articulation posant problème avec l'orientation initiale de la tête permet, moyennant des moyens d'entraînement en rotation de la tête et des moyens de commande adéquats, d'assurer une descente des doigts entre les nervures et ensuite un positionnement angulaire constant. The detection of angular positions of the problematic joint with the initial orientation of the head allows, by means of training means rotation of the head and adequate control means, to ensure a descent of the fingers between the ribs and then a constant angular positioning.
La détection de la position angulaire au niveau de l'encoche de l'élément mobile en translation des moyens d'amenée automatique des articulations en face de la tête mobile permet une optimisation du temps de cycle de travail du dispositif. En effet, en cas de non détection ou de non interruption du faisceau lors de positions angulaires de l'articulation telles que celles illustrées à la figure 5, la tête peut subir la première rotation de 90° durant le transfert de l'articulation opéré par le déplacement en translation de l'élément mobile 36. C'est donc en temps caché que la position angulaire de la tête peut être adaptée à la position angulaire initiale de l'articulation. Il est en effet à noter que l'orientation de l'articulation dés lors qu'elle est logée dans l'encoche ne change pas durant son transfert jusqu'à la zone de réception suivant l'axe de la tête mobile et du support. The detection of the angular position at the notch of the movable member in translation of the automatic feed means of the joints in front of the movable head allows an optimization of the working cycle time of the device. Indeed, in case of non-detection or non-interruption of the beam at angular positions of the joint such as those illustrated in Figure 5, the head can undergo the first rotation of 90 ° during the transfer of the joint operated by the displacement in translation of the movable member 36. It is therefore in hidden time that the angular position of the head can be adapted to the initial angular position of the joint. It should be noted that the orientation of the articulation as soon as it is housed in the notch does not change during its transfer to the receiving zone along the axis of the movable head and the support.
