Description

DISPOSITIF DE DISTRIBUTION UNITAIRE DE PIÈCES TELS LES RIVETS DEVICE FOR THE UNITARY DISTRIBUTION OF PARTS SUCH AS RIVETS
DOMAINE D'APPLICATION DE L'INVENTION La présente invention a trait au domaine de la distribution de pièces tels les rivets et aux adaptations permettant de réaliser une distribution unitaire dans les meilleures conditions. DESCRIPTION DE L'ART ANTÉRIEUR Les demandeurs ont constaté que la plupart des dispositifs existants de distribution de pièces tels les rivets n'autorise pas la garantie d'une distribution unitaire des pièces, condition sine qua non pour un bon fonctionnement des sous-ensembles technologiques présents en aval desdits dispositifs tels des moyens de stockage, têtes de perçage et/ou rivetage, etc.. Cette absence de garantie requiert une installation plus complexe intégrant notamment des moyens de détection, d'évacuation, de retenue ou de retournement des pièces afin d'éviter toute dégradation des sous-ensembles technologiques présents en aval. Une difficulté à laquelle sont confrontés les concepteurs de tels dispositifs réside dans le fait que dans certaines applications, les pièces sont mises en mouvement au moyen d'un fluide de transport tel de l'air comprimé. Or, un dispositif susceptible de contrôler une distribution unitaire forme un sas qui peut devenir un obstacle non seulement aux pièces mais également à la bonne circulation de l'air. DESCRIPTION DE L'INVENTION Partant de cet état de fait, les demandeurs ont mené des recherches visant à garantir une distribution unitaire des pièces tels des rivets circulant à l'intérieur d'une conduite. Ces recherches ont abouti à la conception d'un dispositif qui, par ses spécificités, garantit la distribution unitaire des pièces à l'intérieur de la conduite à laquelle il est intégré. Selon l'invention, le dispositif de distribution unitaire de pièces tels des rivets circulant à l'intérieur d'au moins une conduite, est remarquable en ce qu'il est constitué par au moins un moyen de mise en mouvement indépendant d'au moins deux tiges qui viennent traverser ladite conduite de déplacement et qui, selon la position alternativement adoptée, présentent ou non un obstacle à la circulation des pièces, le moyen de mise en mouvement alternatif étant un vérin alternatif à deux tiges dont la rentrée et/ou la sortie de tige sont par défaut commandées pour que la rentrée d'une tige ne soit possible qu'après la sortie totale de l'autre, ou vice-versa, de façon à réaliser une position où les deux tiges forment à l'intérieur de la conduite, un obstacle au déplacement des pièces préalablement à tout déplacement de l'une ou l'autre tige à des fins d'autorisation de passage. L'invention s'appuie sur au moins deux spécificités :FIELD OF APPLICATION OF THE INVENTION The present invention relates to the field of the distribution of parts such as rivets and to adaptations making it possible to produce a unitary distribution under the best conditions. DESCRIPTION OF THE PRIOR ART The applicants have observed that most of the existing devices for distributing parts, such as rivets, do not allow the guarantee of a unitary distribution of the parts, a sine qua non condition for the proper functioning of the technological sub-assemblies. present downstream of said devices such as storage means, drilling heads and / or riveting, etc. This absence of warranty requires a more complex installation including in particular means of detection, evacuation, retention or turning of the parts in order to avoid any degradation of the technological subsets present downstream. A difficulty faced by the designers of such devices lies in the fact that in certain applications, the parts are moved by means of a transport fluid such as compressed air. However, a device capable of controlling a unitary distribution forms an airlock which can become an obstacle not only to the rooms but also to the good circulation of air. DESCRIPTION OF THE INVENTION On the basis of this fact, the applicants have carried out research aimed at guaranteeing a unitary distribution of parts such as rivets circulating inside a pipe. This research led to the design of a device which, by its specificities, guarantees the unitary distribution of the parts inside the pipe in which it is integrated. According to the invention, the unitary device for distributing parts such as rivets circulating inside at least one pipe, is remarkable in that it is constituted by at least one means of setting in motion independent of at least two rods which come through said displacement pipe and which, depending on the alternately adopted position, present or not an obstacle to the circulation of the parts, the means of reciprocating movement being an alternating cylinder with two rods, the re-entry and / or the rod exit are by default controlled so that the re-entry of one rod is only possible after the total exit of the other, or vice-versa, so as to achieve a position where the two rods form inside driving, an obstacle to the movement of parts prior to any movement of one or the other rod for the purpose of authorizing passage. The invention is based on at least two specificities:
- la présence d'un seul actionneur pour la mise en mouvement de deux tiges servant à venir faire obstacle aux mouvements des pièces dans la conduite,- the presence of a single actuator for setting in motion two rods serving to obstruct the movements of the parts in the pipe,
- un fonctionnement à quatre temps c'est à dire où tout retrait d'obstacle dans la conduite n'a pu être réalisé qu'après une position des tiges où elles formaient toutes les deux un obstacle dans la conduite. La présence d'un seul actionneur pour la mise en mouvement de deux tiges évite de façon absolue, que ces deux dernières puissent être mises en mouvement sans tenir compte de l'autre, ce que ne peut garantir un dispositif où chaque tige serait mise en mouvement par un actionneur indépendant. De même, il doit être compris que la formation d'un obstacle n'est pas dépendante de la sortie des tiges ces dernières pouvant être préformées et disposées par rapport à la conduite de sorte que ce soit la rentrée de tige qui place un obstacle dans la conduite. Quelle que soit cette préformation, l'invention prévoit que l'enlèvement ou le retrait de l'obstacle formé par une tige ne puisse être réalisé qu'après que les deux tiges aient été dans une position où elles formaient toutes les deux un obstacle garantissant ainsi de façon absolue, une distribution unitaire des pièces. Conformément à l'invention, chaque tige met en mouvement une fourchette comprenant deux doigts qui, viennent traverser la conduite de déplacement des pièces et définissent comme illustrés, lorsqu'ils forment un obstacle au déplacement des pièces dans la conduite un écart susceptible de permettre le passage des tiges des rivets mais non de la tête retenant ainsi les rivets dans cette position. De même, dans la position où ils ne font pas obstacle au déplacement, les doigts présentent un évidement symétrique autorisant le passage de la tête. Le mouvement alternatif de ces deux fourchettes associé à une disposition particulière de ces dernières l'une par rapport à l'autre, à savoir que la distance les séparant est inférieure à la plus petite longueur de tige des rivets susceptibles de se déplacer à l'intérieur de la conduite, garantit une distribution unitaire des pièces en sortie du dispositif de l'invention. Les concepts fondamentaux de l'invention viennent d'être exposés ci-dessus dans leur forme la plus élémentaire. D'autres détails et caractéristiques ressortiront plus clairement à la lecture de la description qui suit et en regard des dessins annexés, donnant à titre d'exemple non limitatif, un mode de réalisation d'un dispositif conforme à l'invention. BRÈVE DESCRIPTION DES DESSINS La figure 1 est un dessin en vue extérieure en perspective d'un mode de réalisation du dispositif associé à un moyen de connexion à une conduite de déplacement des pièces à distribuer, La figure 2 est un dessin schématique en vue extérieure en perspective du dispositif illustré en figure 1 sans son moyen de connexion, la figure 3 est un dessin schématique présentant une vue en coupe partielle du dispositif de l'invention, Les figures 4a, 4b, 4c, 5d et 5e sont des dessins en vue en coupe du dispositif de l'invention illustrant les positions prises de par le mouvement alternatif des tiges, Les figures 5a et 6a, sont des dessins schématiques de détail illustrant la traversée de la conduite par les doigts lors de la position présentée en figure 4a, Les figures 5b et 6b sont des dessins schématiques de détail illustrant la traversée de la conduite par les doigts lors de la position présentée en figure 4b, Les figures 5c et 6c sont des dessins schématiques de détail illustrant la traversée de la conduite par les doigts lors de la position présentée en figure 4c, les figures 5d et 6d sont des dessins schématiques de détail illustrant la traversée de la conduite par les doigts lors de la position présentée en figure 4d, les figures 5e et 6e sont des dessins schématiques de détail illustrant la traversée de la conduite par les doigts lors de la position présentée en figure 4e. DESCRIPTION DES MODES DE RÉALISATION PRÉFÉRÉS Tel qu'illustré sur le dessin de la figure 1, le dispositif référencé D dans son ensemble de distribution unitaire de pièces tels des rivets circulant à l'intérieur d'au moins une conduite ici non représentée, est constitué par au moins un moyen de mise en mouvement 100 indépendant d'au moins deux tiges 110 et 120 qui, selon la position alternativement, présentent toujours un obstacle à la circulation des pièces à l'intérieur de la conduite. Plus précisément, le dispositif D est constitué par un vérin constituant le moyen de mise en mouvement 100 fixé à une platine 200 solidaire d'un corps 300 ménagé d'au moins un alésage (ou conduite intérieure) 310 (cf. figure 3) auquel se connecte ladite conduite, les mouvements des tiges 110 et 120 du vérin venant introduire ou non à l'intérieur de l'alésage 310 un obstacle à la circulation des pièces. Comme illustrée sur les dessins des figures 2 et 3, chaque tige 110 et 120 met en mouvement une fourchette comprenant deux doigts 111 et 112 pour la tige 110 et 121 et 122 pour la tige 120 qui viennent traverser la conduite C de déplacement des pièces P dont le sens de mouvement est modélisé par la flèche F. Selon une caractéristique particulièrement avantageuse, les doigts formant chaque fourchette définissent un écart. Cet écart est susceptible de permettre le passage des tiges des rivets mais non de la tête retenant ainsi les rivets dans cette position telle celle illustrée en figure 3. Ainsi, le dispositif de l'invention retient le déplacement des pièces au niveau de leur tête. L'utilisation d'une paire de doigts écartés comme obstacle à la circulation des pièces P a pour avantage d'autoriser le passage du fluide de mise en mouvement tel l'air comprimé dans la conduite. Ainsi, le sas formé par le dispositif n'influe pas sur la circulation du fluide de déplacement. En outre, les doigts formant chaque fourchette 110 et 120 présentent un évidement symétrique 113 et 123 qui, lorsqu'il vient coaxial à l'axe de déplacement des pièces dans la conduite P ou dans l'alésage 310, autorise le passage de la tête de la pièce P. Selon le mode de réalisation illustré, l' évidement forme un passage circulaire et est situé sur la longueur des doigts de façon à ce que lors de la rentrée de la tige, la fourchette à laquelle il est associé positionne- Four-stroke operation, that is to say where any obstacle removal in the pipe could only be achieved after a position of the rods where they both formed an obstacle in the pipe. The presence of a single actuator for setting two rods in motion absolutely prevents the latter two from being able to be set in motion without taking account of the other, which cannot be guaranteed by a device in which each rod is set movement by an independent actuator. Likewise, it should be understood that the formation of an obstacle is not dependent on the exit of the rods, the latter being able to be preformed and arranged with respect to the pipe so that it is the retraction of the rod which places an obstacle in the driving. Whatever this preformation, the invention provides that the removal or removal of the obstacle formed by a rod can only be produced after the two rods have been in a position where they both form an obstacle, thus guaranteeing absolute distribution of the parts. According to the invention, each rod sets in motion a fork comprising two fingers which cross the pipe for moving the parts and define, as illustrated, when they form an obstacle to the movement of the pieces in the pipe, a gap capable of allowing the passage of the rods of the rivets but not of the head thus retaining the rivets in this position. Similarly, in the position where they do not prevent movement, the fingers have a symmetrical recess allowing the passage of the head. The reciprocating movement of these two forks associated with a particular arrangement of the latter relative to each other, namely that the distance separating them is less than the shortest length of rod of the rivets capable of moving with the inside the pipe, guarantees a unitary distribution of the parts leaving the device of the invention. The fundamental concepts of the invention have just been exposed above in their most basic form. Other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving by way of nonlimiting example, an embodiment of a device according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a drawing in external perspective view of an embodiment of the device associated with a means of connection to a pipe for moving the parts to be dispensed, FIG. 2 is a schematic drawing in external view in perspective of the device illustrated in FIG. 1 without its connection means, Figure 3 is a schematic drawing showing a partial sectional view of the device of the invention, Figures 4a, 4b, 4c, 5d and 5e are drawings in sectional view of the device of the invention illustrating the positions taken from the reciprocating movement of the rods, FIGS. 5a and 6a, are schematic detail drawings illustrating the crossing of the pipe by the fingers during the position presented in FIG. 4a, FIGS. 5b and 6b are schematic detailed drawings illustrating the crossing of the pipe by the fingers during the position shown in FIG. 4b, FIGS. 5c and 6c are schematic detail drawings illustrating the crossing of the pipe by the fingers during the position presented in FIG. 4c, FIGS. 5d and 6d are schematic detail drawings illustrating the crossing of the pipe by the fingers during the position presented in FIG. 4d, FIGS. 5e and 6e are schematic detail drawings ill Using the fingers to cross the pipe during the position shown in Figure 4e. DESCRIPTION OF THE PREFERRED EMBODIMENTS As illustrated in the drawing of FIG. 1, the device referenced D in its unitary distribution assembly of parts such as rivets circulating inside at least one pipe here not shown, is constituted by at least one moving means 100 independent of at least two rods 110 and 120 which, depending on the position alternately, always present an obstacle to the circulation of the parts inside the pipe. More specifically, the device D is constituted by a jack constituting the means of setting in motion 100 fixed to a plate 200 integral with a body 300 formed by at least one bore (or internal pipe) 310 (cf. FIG. 3) to which connects said pipe, the movements of the rods 110 and 120 of the jack coming or not introducing inside the bore 310 an obstacle to the circulation of coins. As illustrated in the drawings of FIGS. 2 and 3, each rod 110 and 120 sets in motion a fork comprising two fingers 111 and 112 for the rod 110 and 121 and 122 for the rod 120 which pass through the pipe C for moving the parts P whose direction of movement is modeled by the arrow F. According to a particularly advantageous characteristic, the fingers forming each fork define a gap. This difference is capable of allowing the passage of the rods of the rivets but not of the head, thus retaining the rivets in this position such as that illustrated in FIG. 3. Thus, the device of the invention retains the movement of the parts at their head. The use of a pair of spaced fingers as an obstacle to the circulation of the parts P has the advantage of authorizing the passage of the fluid for setting in motion such as the compressed air in the pipe. Thus, the airlock formed by the device does not influence the circulation of the displacement fluid. In addition, the fingers forming each fork 110 and 120 have a symmetrical recess 113 and 123 which, when it comes coaxial with the axis of movement of the parts in the pipe P or in the bore 310, authorizes the passage of the head of the part P. According to the illustrated embodiment, the recess forms a circular passage and is located along the length of the fingers so that when the rod is retracted, the fork with which it is associated positions

Comme illustrée sur les dessins des figures 4a et 6a, la tige de la fourchette 110 située en aval par rapport au sens d'avancée est rentrée de sorte que l'évidement 113 ménagé dans les doigts 111 et 112 vienne se positionner coaxialement avec l'axe de déplacement des pièces P. Comme illustrée sur les dessins des figure 4b, 5b, 6b et conformément au procédé de travail de l'invention, la tige de la fourchette 110 sort de façon à ce que les doigts 111 et 112 auxquels elle est associée viennent, comme les doigts 121 et 122, former un obstacle au déplacement des pièces P. La tige de la fourchette 120 reste quant à elle en position. L'étape suivante illustrée par les dessins des figures 4c, 5c et 6c consiste à faire rentrer la tige de la fourchette 120 de façon à ce que l'évidement 123 vienne se positionner coaxialement avec l'axe de déplacement des pièces P autorisant ainsi le rivet Pi mu par exemple par un fluide de mise en mouvement tel de l'air comprimé, à venir en butée sur la fourchette 110 située en aval. Les dessins des figures 4d, 5d et 6d illustrent l'étape suivante et la spécificité du procédé de l'invention en montrant que les deux tiges des fourchettes 110 et 120 sont sorties de façon à former toutes les deux un obstacle aux déplacements des pièces où le rivet PI est maintenu arrêté par la fourchette 110 et où le rivet P suivant PI est arrêté par la fourchette 120. Les dessins des figures 4e, 5e et 6e montrent la rentrée de la tige à laquelle est liée la fourchette 110 venant mettre en correspondance l'évidement 113 avec le conduit de déplacement de sorte que Pi est libéré alors que le rivet suivant PI reste en appui par sa tête sur les doigts 121 et 122 de la fourchette 120. On comprend que le dispositif et le procédé qui viennent d'être ci-dessus décrits et représentés, l'ont été en vue d'une divulgation plutôt que d'une limitation. Bien entendu, divers aménagements, modifications et — o —

As illustrated in the drawings of FIGS. 4a and 6a, the rod of the fork 110 situated downstream relative to the direction of advance is retracted so that the recess 113 formed in the fingers 111 and 112 comes to be positioned coaxially with the axis of movement of the parts P. As illustrated in the drawings in FIGS. 4b, 5b, 6b and in accordance with the working method of the invention, the rod of the fork 110 comes out so that the fingers 111 and 112 to which it is associated, like fingers 121 and 122, form an obstacle to the movement of the parts P. The rod of the fork 120 remains in turn in position. The next step illustrated by the drawings of FIGS. 4c, 5c and 6c consists in bringing in the rod of the fork 120 so that the recess 123 comes to be positioned coaxially with the axis of movement of the parts P thus authorizing the Pi mu rivet for example by a fluid for setting in motion such as compressed air, coming into abutment on the fork 110 located downstream. The drawings of FIGS. 4d, 5d and 6d illustrate the next step and the specificity of the method of the invention by showing that the two rods of the forks 110 and 120 are pulled out so as to both form an obstacle to the movement of the parts where the rivet PI is kept stopped by the fork 110 and where the rivet P according to PI is stopped by the fork 120. The drawings in FIGS. 4e, 5e and 6e show the reentry of the rod to which the fork 110 is linked coming to match the recess 113 with the displacement conduit so that Pi is released while the following rivet PI remains in abutment by its head on the fingers 121 and 122 of the fork 120. It is understood that the device and the method which have just be described above and shown, were for disclosure rather than limitation. Of course, various arrangements, modifications and - o -
améliorations pourront être apportés à l'exemple ci- dessus, sans pour autant sortir du cadre de l'invention. Ainsi par exemple, bien que le dispositif soit illustré associé à une seule et même conduite, le mouvement alternatif des tiges pourra voir ses effets prolongés sur d'autres conduites dont l'axe est parallèle à celui de la première. improvements could be made to the above example, without departing from the scope of the invention. Thus, for example, although the device is illustrated associated with one and the same pipe, the reciprocating movement of the rods may have its effects prolonged on other pipes whose axis is parallel to that of the first.
