Definitions
- the invention relates to a method of assembling a bottom or cover on a box body, by internal roll; it also relates to an assembly machine capable of carrying out this process.
- the invention makes it possible to resolve these drawbacks by proposing a new method of assembling the bottom or cover on the box body, resulting in internal crimping in a protruding bead at the periphery of the corresponding end of the box.
- the basic idea of the invention consists in using a preformed rolled edge on said bottom or cover as a bearing or reaction surface, during the internal rolling of the extreme portion of the box body.
- the invention therefore relates to a method of assembling a bottom or cover to a box body, characterized in that it consists: - placing in a matrix provided with a rolling surface a bottom or cover with an inwardly rolled edge, so that the latter defines a bearing surface conforming substantially to at least part of said rolling surface; and - Engaging an end portion of said box body between said rolling surface and said support surface and pushing said box body until the rolling of this end portion enveloping said support surface.
- the invention also relates to a machine for assembling a box body and a bottom or cover, characterized in that it comprises at least one rolling die comprising a socket or the like defining a first part of the rolling surface. , radially inward and jaws arranged along a perimeter corresponding to the shape of said box, movable inside said socket and movable in the direction of the internal wall thereof, these jaws being shaped to define, at least partially, a second part of the rolling surface radially outward, extending said first part in a position close to said jaws and said internal wall of said sleeve.
- This machine mainly consists of a drum 14 rotating around its main axis 15 for the sequencing of the different operations and here carrying four assembly assemblies 16 each comprising a rolling die 18 and a piston 19.
- the four assemblies assemblies are regularly arranged at the periphery of the drum and angularly offset by 90 ° with respect to each other.
- Each rolling die 18 comprises a socket 20 in the general shape of a bell, housing jaws 21, which can move radially under the action of a pusher 22 having a bearing area of variable section axially and movable along an axis parallel to arrow A (FIG. 8).
- the sleeve 20 has a circular lower opening while the jaws 21 are arranged regularly circumferentially inside said sleeve, the bearing section variable being here a frustoconical bearing 26. It goes without saying, however, that these shapes are dictated only by that of the crimping contour.
- the arrangement of the jaws and the shape of the pusher can be significantly modified without departing from the scope of the invention, the necessary structural modifications being within the scope of the skilled in the art.
- the rolling surface is distributed in the matrix 18 between the internal surface of the sleeve 20, in the vicinity of its lower opening and of the surface portions of the jaws 21. More precisely, the sleeve 20 defines a first part 20 a of the rolling surface, extending progressively radially inwards from the edge of its opening and having a suitable curved radial profile, while each jaw 21 has a curved profile surface 21 has extended in its lower part a small protruding flange 25. all the surfaces 21 thus form a second portion of the rolling surface, discontinuous circumferentially oriented generally outward and extending said first portion 20 a of that rolling surface when said jaws are brought closer to the internal wall of said bushing, under the action of pusher 22.
- Each rolling die 18 is disposed above a piston 19, the axis of symmetry of which is aligned with the axis of the pusher.
- This piston is shaped to receive a box body 13, vertically, that is to say with an axial end of said box body resting on the upper surface of the piston. To this end, it is provided with a slight relief 31 in the form of a disc, the diameter of which corresponds to the internal diameter of the box body.
- the piston is movable along the actuation axis of the pusher, that is to say here vertically. More specifically, the drum 14 mainly comprises two horizontal plates 33 and 34 spaced from one another and separated by a cylindrical part 36 of smaller diameter.
- the lower plate 34 houses the pistons 19 in corresponding bores, and the lower faces of these pistons open from the lower face of the plate in order to be able to meet a lifting ramp 40, fixed, or a similar actuation means.
- the upper plate 33 carries the dies 18 aligned with the pistons 19.
- the cylindrical part 36 is provided with lateral recesses 37, semi-cylindrical, of shape and dimension suitable for receiving and driving bodies of boxes 13. These are introduced between the plates 33 and 34 by a conveying means 39 provided with a slide 39 a and a broad-threaded screw 39 b driving said box bodies.
- the bottoms or covers 12 are also introduced between the plates 33 and 34, by another suitable conveying means 42, here in the form of a conveyor belt.
- the end parts of the conveying parts 39 and 42 are arranged substantially tangentially to the drum 14, between the plates 33 and 34.
- An auxiliary evacuation cylinder 45 provided with semi-cylindrical lateral recesses 46 is mounted rotating in the vicinity of the periphery of the cylindrical part 36. It is rotated in synchronism with the drum 14 and cooperates with a guide 48 for depositing the box bodies provided with their bottoms or covers on a conveying means 49 conveying them to a clamping station shown in FIG. 7.
- the latter is conventional and essentially comprises two knobs 52, 54 between which the internal rolled fastening the box body 13 and the bottom or cover 12, is capable of being crushed radially to ensure a perfect seal of the assembly.
- the funds or covers 12 which are routed to the matrices 18 are preformed to include each a rolled edge inward 12 a.
- This rolled edge can conventionally be obtained by stamping, using a tool of suitable shape, which it has not been deemed useful to represent, this operation being in itself trivial.
- the bases or covers 12 thus preformed are deposited on the conveying means 42 so that said rolled edges 12 a are oriented towards the plate 33 when the bottom or cover reaches the end of said conveying means. The movement of the latter is synchronized with the rotation of the drum 14 so that a bottom or cover 12 reaches below a die 18, in the situation illustrated in FIG. 2.
- the pusher 22 then lowers until 'that the gripping means 29 comes into contact with the central part of the bottom or cover 12. This is the situation illustrated in FIG. 3.
- the jaws 21 are set back relative to the surface internal of the sleeve 20, since the frustoconical bearing 26 is not in contact with said jaws.
- the pusher 22 is actuated in the direction of arrow A, which has the double consequence of placing the rolled edge 12 a opposite said first part 20 a of the rolling surface , then cause the radial displacement of the jaws 21 for completely enclosing the rolled edge 12 a in the annular space defined between the parts 20 a and 21 a of said rolling surface.
- the invention is applicable to the assembly of a deformable bottom or cover which is not necessarily metallic on a metal box body.

Abstract
Description
L'invention concerne un procédé d'assemblage d'un fond ou couvercle sur un corps de boîte, par roulé-interne; elle concerne également une machine d'assemblage susceptible d'exécuter ce procédé.The invention relates to a method of assembling a bottom or cover on a box body, by internal roll; it also relates to an assembly machine capable of carrying out this process.
De nombreuses boîtes, au moins en partie métalliques, sont réalisées par un sertissage périphérique créant un bourrelet faisant circonférentiellement saillie aux extrémités de la boîte. Ce bourrelet constitue une zone particulièrement sensible à la corrosion (formation de rouille lorsque la boîte séjourne dans un lieu humide, comme par exemple une salle de bain). En outre, ils sont inesthétiques, ce qui peut constituer un inconvénient pour certains articles comme par exemple des produits de parfumerie vendus en conteneurs de type aérosol. Dans ce domaine particulier où la décoration de l'emballage est importante pour la promotion du produit, la présence du bourrelet interrompt le décor et souligne de façon inesthétique l'extrémité de l'emballage. En outre, du fait que le processus de sertissage est effectué après la décoration peinte et vernie du corps de boîte, les outils de sertissage connus endommagent ce revêtement, ce qui est l'une des causes de la vulnérabilité à la corrosion de cette zone. Enfin, la présence du bourrelet externe empêche l'empilage de tels emballages métalliques, ce qui pose des problèmes pour le stockage et la manutention.Many boxes, at least partly metallic, are produced by a peripheral crimping creating a bead circumferentially projecting at the ends of the box. This bead constitutes an area particularly sensitive to corrosion (formation of rust when the box stays in a humid place, such as for example a bathroom). In addition, they are unsightly, which can be a drawback for certain articles such as, for example, perfumery products sold in aerosol type containers. In this particular area where the decoration of the packaging is important for the promotion of the product, the presence of the bead interrupts the decoration and unaesthetically emphasizes the end of the packaging. In addition, since the crimping process is carried out after the painted and varnished decoration of the box body, the known crimping tools damage this coating, which is one of the causes of the vulnerability to corrosion of this area. Finally, the presence of the external bead prevents the stacking of such metal packaging, which poses problems for storage and handling.
Des tentatives ont été effectuées pour réaliser un sertissage interne, non saillant, comme en témoigne, par exemple, le brevet américain No 3452897. Cependant, à ce jour, ce type de sertissage ne semble pas exploité industriellement. En outre, sa mise en oeuvre nécessite une soudure avant les opérations aboutissant à l'élaboration dudit sertissage interne, ce qui augmente sensiblement les coûts de fabrication.Attempts have been made to achieve an internal crimping, non-protruding, as evidenced, for example, US Patent No. 3452897. However, to date, this type of setting does not appear exploited industrially. In addition, its implementation requires welding before the operations leading to the development of said internal crimping, which significantly increases the manufacturing costs.
L'invention permet de résoudre ces inconvénients en proposant un nouveau procédé d'assemblage du fond ou couvercle sur le corps de boîte, aboutissant à un sertissage interne dans bourrelet saillant à la périphérie de l'extrémité correspondante de la boîte. L'idée de base de l'invention consiste à utiliser un bord roulé préformé sur ledit fond ou couvercle en tant que surface d'appui ou de réaction, pendant le roulage interne de la portion extrême du corps de boîte.The invention makes it possible to resolve these drawbacks by proposing a new method of assembling the bottom or cover on the box body, resulting in internal crimping in a protruding bead at the periphery of the corresponding end of the box. The basic idea of the invention consists in using a preformed rolled edge on said bottom or cover as a bearing or reaction surface, during the internal rolling of the extreme portion of the box body.
Plus précisément, l'invention concerne donc un procédé d'assemblage d'un fond ou couvercle à un corps de boîte, caractérisé en ce qu'il consiste:
- à placer dans une matrice munie d'une surface de roulage un fond ou couvercle à bord roulé vers l'intérieur, de façon que celui-ci définisse une surface d'appui épousant sensiblement au moins une partie de ladite surface de roulage; et
- à engager une portion extrême dudit corps de boîte entre ladite surface de roulage et ladite surface d'appui et à repousser ledit corps de boîte jusqu'à provoquer le roulage de cette portion extrême enveloppant ladite surface d'appui.More specifically, the invention therefore relates to a method of assembling a bottom or cover to a box body, characterized in that it consists:
- placing in a matrix provided with a rolling surface a bottom or cover with an inwardly rolled edge, so that the latter defines a bearing surface conforming substantially to at least part of said rolling surface; and
- Engaging an end portion of said box body between said rolling surface and said support surface and pushing said box body until the rolling of this end portion enveloping said support surface.
L'invention concerne également une machine d'assemblage d'un corps de boîte et d'un fond ou couvercle, caractérisée en ce qu'elle comporte au moins une matrice de roulage comprenant une douille ou analogue définissant une première partie de surface de roulage, radialement vers l'intérieur et des mâchoires agencées le long d'un périmètre correspondant à la forme de ladite boîte, mobiles à l'intérieur de ladite douille et déplaçables en direction de la paroi interne de celle-ci, ces mâchoires étant conformées pour définir, au moins partiellement, une second partie de surface de roulage radialement vers l'extérieur, prolongeant ladite première partie en position rapprochée desdites mâchoires et de ladite paroi interne de ladite douille.The invention also relates to a machine for assembling a box body and a bottom or cover, characterized in that it comprises at least one rolling die comprising a socket or the like defining a first part of the rolling surface. , radially inward and jaws arranged along a perimeter corresponding to the shape of said box, movable inside said socket and movable in the direction of the internal wall thereof, these jaws being shaped to define, at least partially, a second part of the rolling surface radially outward, extending said first part in a position close to said jaws and said internal wall of said sleeve.

En se référant aux dessins, on a représenté une machine 11 d'assemblage de fonds ou couvercles 12 à des corps de boîte 13, tubulaires, respectifs. Cette machine se compose principalement d'un tambour 14 tournant autour de son axe principal 15 pour le séquencement des différentes opérations et portant ici quatre ensembles d'assemblage 16 comportant chacun une matrice de roulage 18 et un piston 19. Les quatre ensembles d'assemblages sont régulièrement disposés à la périphérie du tambour et angulairement décalés de 90° les uns par rapport aux autres. Chaque matrice de roulage 18 comporte une douille 20 en forme générale de cloche, abritant des mâchoires 21, mobiles radialement sous l'action d'un poussoir 22 présentant une portée à section variable axialement et mobile selon un axe parallèle à la flèche A (figure 8). Dans l'exemple représenté, concernant l'assemblage de fonds circulaires et de corps de boîte cylindriques, la douille 20 présente une ouverture inférieure circulaire tandis que les mâchoires 21 sont agencées régulièrement circonférentiellement à l'intérieur de ladite douille, la portée à section variable étant ici une portée tronconique 26. Il va de soi cependant, que ces formes ne sont dictées que par celle du contour de sertissage. En fonction de la forme de la boîte, la forme de la douille, l'agencement des mâchoires et la forme du poussoir pourront être notablement modifiés sans sortir du cadre de l'invention, les modifications de structure nécessaires étant à la portée de l'homme du métier.Referring to the drawings, there is shown a
Selon une caractéristique importante de l'invention, la surface de roulage se trouve répartie dans la matrice 18 entre la surface interne de la douille 20, au voisinage de son ouverture inférieure et des portions de surface des mâchoires 21. Plus précisément, la douille 20 définit une première partie 20a de la surface de roulage, s'étendant progressivement radialement vers l'intérieur à partir du bord de son ouverture et présentant un profil radial courbe adapté, tandis que chaque mâchoire 21 présente une surface à profil courbe 21a prolongée à sa partie inférieure par un petit bourrelet saillant 25. L'ensemble des surfaces 21a forme ainsi une seconde partie de la surface de roulage, discontinue circonférentiellement, globalement orientée vers l'extérieur et prolongeant ladite première partie 20a de cette surface de roulage lorsque lesdites mâchoires sont rapprochées de la paroi interne de ladite douille, sous l'action du poussoir 22. Cette situation est clairement visible sur la figure 8. On voit que les mâchoires sont repoussées radialement vers l'extérieur lorsque le poussoir est déplacé axialement dans le sens de la flèche A, c'est-à-dire lorsque sa portée tronconique 26 repousse l'ensemble des mâchoires radialement vers l'extérieur, en prenant appui sur leurs faces arrière. Un anneau élastique 27 en matériau élastomère est disposé dans un logement défini par des portions de gorge pratiquées à l'extérieur des mâchoires, de façon à solliciter ces dernières dans la sens d'un retrait radial, lorsque le poussoir est actionné en sens inverse de celui indiqué par la flèche A. D'autre part, la partie inférieure du poussoir porte un moyen de préhension 29, ici sous forme d'une ventouse, susceptible de retenir un fond ou couvercle 12. La fiabilité de la préhension par la ventouse est améliorée grâce à un moyen d'aspiration, non représentée, séquentiellement raccordé à un conduit 30 traversant axialement le poussoir 18 et débouchant au centre de ladite ventouse 29.According to an important characteristic of the invention, the rolling surface is distributed in the
Chaque matrice de roulage 18 est disposée au-dessus d'un piston 19, dont l'axe de symétrie est aligné avec l'axe du poussoir. Ce piston est conformé pour recevoir un corps de boîte 13, verticalement, c'est-à-dire avec une extrémité axiale dudit corps de boîte reposant sur la surface supérieure du piston. A cet effet, celle-ci est munie d'un léger relief 31 en forme de disque dont le diamètre correspond au diamètre interne du corps de boîte. Le piston est déplaçable selon l'axe d'actionnement du poussoir, c'est-à-dire ici verticalement. Plus précisément, le tambour 14 comporte principalement deux plateaux horizontaux 33 et 34 espacés l'un de l'autre et séparés par une partie cylindrique 36 de plus faible diamètre. Le plateau inférieur 34 abrite les pistons 19 dans des alésages correspondants, et les faces inférieures de ces pistons débouchent de la face inférieure du plateau pour pouvoir rencontrer une rampe de levage 40, fixe, ou un moyen d'actionnement analogue. Le plateau supérieur 33 porte les matrices 18 alignées avec les pistons 19. La partie cylindrique 36 est munie de creusures latérales 37, semi-cylindriques, de forme et dimension propres à accueillir et entraîner des corps de boîtes 13. Ceux-ci sont introduits entre les plateaux 33 et 34 par un moyen de convoyage 39 muni d'une glissière 39a et d'une vis à large filet 39b entraînant lesdits corps de boîtes. Les fonds ou couvercles 12 sont aussi introduits entre les plateaux 33 et 34, par un autre moyen de convoyage 42 adapté, ici sous forme d'une bande transporteuse. Les parties extrêmes des parties de convoyage 39 et 42 sont agencées sensiblement tangentiellement au tambour 14, entre les plateaux 33 et 34. Un cylindre auxiliaire d'évacuation 45 muni de creusures latérales semi-cylindriques 46 est monté tournant au voisinage de la périphérie de la partie cylindrique 36. Il est entraîné en rotation en synchronisme avec le tambour 14 et coopère avec un guide 48 pour déposer les corps de boîtes munis de leurs fonds ou couvercles sur un moyen de convoyage 49 les acheminant vers un poste de serrage représenté à la figure 7. Ce dernier est classique et comporte essentiellement deux molettes 52, 54 entre lesquelles le roulé interne solidarisant le corps de boîte 13 et le fond ou couvercle 12, est susceptible d'être écrasé radialement pour assurer une parfaite étanchéité de l'assemblage.Each rolling
On va maintenant décrire la mise en oeuvre du procédé de l'invention, plus particulièrement illustré aux figures 2 à 6.We will now describe the implementation of the method of the invention, more particularly illustrated in FIGS. 2 to 6.
Il convient de noter que les fonds ou couvercles 12 qui sont acheminés vers les matrices 18 sont préformés pour comporter, chacun, un bord roulé vers l'intérieur 12a. Ce bord roulé peut être obtenu classiquement par emboutissage, au moyen d'un outil de forme adaptée, qu'il n'a pas été jugé utile de représenter, cette opération étant en soi banale. Les fonds ou couvercles 12 ainsi préformés sont déposés sur le moyen de convoyage 42 de façon que lesdits bords roulés 12a soient orientés vers le plateau 33 lorsque les fond ou couvercle parviennent à l'extrémité dudit moyen de convoyage. Le mouvement de celui-ci est synchronisé à la rotation du tambour 14 de façon qu'un fond ou couvercle 12 parvienne en-dessous d'une matrice 18, dans la situation illustrée à la figure 2. Le poussoir 22 s'abaisse alors jusqu'à ce que le moyen de préhension 29 entre en contact avec la partie centrale du fond ou couvercle 12. C'est la situation illustrée à la figure 3. A cette phase du processus, les mâchoires 21 sont en retrait par rapport à la surface interne de la douille 20, puisque la portée tronconique 26 n'est pas en contact avec lesdites mâchoires. Lorsque le fond ou couvercle 12 adhère à la ventouse, le poussoir 22 est actionné dans le sens de la flèche A, ce qui a pour double conséquence de placer le bord roulé 12a en regard de ladite première partie 20a de la surface de roulage, puis de provoquer le déplacement radiale des mâchoires 21 pour emprisonner complètement le bord roulé 12a dans l'espace annulaire défini entre les parties 20a et 21a de ladite surface de roulage. Il est à noter qu'à partir de ce moment, le fond ou couvercle 12 est prisonnier par son bord roulé dans la matrice 18, mais qu'il n'est, en pratique, soumis à aucune contrainite de serrage entre la surface interne de la douille 20 et les mâchoires 21. Le tambour 14 poursuit alors sa rotation jusqu'à l'extrémité du moyen de convoyage 39 où un corps de boîte 13 est positionné sur le piston 19 correspondant. C'est la situation illustrée à la figure 4. La rotation du tambour se poursuit jusqu'à ce que le piston 19 soit actionné vers le haut au moment de son passage sur la rampe 20. C'est la situation illustrée aux figures 5 et 8 qui a pour conséquence d'engager la portion extrême supérieure du corps de boîte entre la surface de roulage 20a, 21a et une surface d'appui définie par le bord roulé 12a du fond ou couvercle lui-même. Ce mouvement a pour conséquence de repousser axialement le corps de boîte 13 jusqu'à provoquer le roulage de la portion extrême de celui-ci engagée dans la matrice, ce roulage enveloppant la surface d'appui définie par le bord roulé 12a. A partir de ce moment, le fond ou couvercle 12 et le corps de boîte 13 sont solidarisés l'un à l'autre. La ventouse 29 est relachée et le piston 19, dépassant la rampe 40, redescend dans son logement. C'est la situation de la figure 6. Puis, l'ensemble, poursuivant sa rotation parvient jusqu'au moyen de convoyage 49 qui l'achemine au poste de serrage illustré à la figure 7. On opère alors un serrage radial des deux portions roulées du corps de boîte et du fond ou couvercle, jusqu'à écraser lesdites portions roulées entre les deux molettes 52 et 54. Cette dernière opération réalise un sertissage parfaitement étanche, sans soudure préalable.It should be noted that the funds or
