Description

La présente invention concerne un plateau en matière en feuille de carton formé de trois pièces séparées.The present invention relates to a tray made of cardboard sheet material formed of three separate pieces.

Elle concerne également un ensemble de flans pour former un tel plateau, un dispositif de formation d'un tel plateau et un procédé correspondant.It also relates to a set of blanks for forming such a plate, a device for forming such a plate and a corresponding method.

Elle trouve une application particulièrement importante bien que non exclusive dans le domaine des plateaux en carton ondulé gerbables, suffisamment résistants pour contenir des produits de formes diverses comme par exemple des fruits ou des sachets semi-rigides du type sachets de soupes, qui ne peuvent donc jouer eux-mêmes un rôle dans la résistance à la compression de l'emballage.It finds a particularly important application although not exclusive in the field of stackable corrugated board trays, sufficiently resistant to contain products of various shapes such as fruit or semi-rigid pouches sachets type of soups, which can not themselves play a role in the compressive strength of the package.

On connaît depuis longtemps les plateaux en carton ondulé mono-flan.We have known for a long time the trays of corrugated cardboard mono-blank.

Ces plateaux ne résistent pas naturellement à la compression autant que les emballages fermés du type caisses américaines.These trays do not naturally resist compression as much as the closed packages of the American box type.

Pour pallier en partie cet inconvénient, il a été proposé des plateaux comprenant des retours ou des poutres d'angle.To overcome this disadvantage, it has been proposed trays comprising returns or corner beams.

Ces dernières ont d'ailleurs ainsi permis de réduire sensiblement les grammages par rapport aux emballages traditionnels.The latter have also made it possible to significantly reduce the grammages compared to traditional packaging.

De tels emballages mono-flan présentent cependant des inconvénients.Such single-blank packages, however, have disadvantages.

En particulier ils ne sont pas facilement gerbables.In particular they are not easily stackable.

En effet pour permettre leur empilage de façon solide et sécurisée, l'art antérieur du plateau prévoit des tenons de gerbage.Indeed to allow their stacking securely and securely, the tray prior art provides stacking tenons.

Or ces derniers sont fragiles et difficiles à introduire de façon précise et répétitive dans les mortaises correspondantes.But these are fragile and difficult to introduce accurately and repetitively in the corresponding mortises.

Un autre inconvénient des plateaux mono-flan connus est dû aux cannelures horizontales de deux faces latérales qui ne participe donc que très faiblement à la résistance à la compression du plateau.Another disadvantage of the known single-flan trays is due to the horizontal splines of two lateral faces which thus participates only very slightly in the compressive strength of the plate.

De plus, quand bien même certains plateaux peuvent être rendus assez résistants à la compression verticale grâce notamment à des trottoirs et/ou des poutres d'angle, le flambage des fonds des plateaux continue quant à lui à poser des problèmes.In addition, even if some trays can be made resistant enough to vertical compression thanks to sidewalks and / or corner beams, buckling tray bottoms continues to cause problems.

Enfin on a malheureusement constaté que le moindre défaut de géométrie des plateaux de l'art antérieur, généralement formés par pistonnage dans une cavité, a un impact important sur leur Résistance à la Compression Verticale (RCV).Finally, it has unfortunately been found that the slightest defect in the geometry of the trays of the prior art, generally formed by swaging in a cavity, has a significant impact on their Resistance to Vertical Compression (RCV).

Les documents FR 2196636 ou DE 3134 666 A1 montrent des emballages correspondant au préambule de la revendication 1.The documents FR 2196636 or DE 3134 666 A1 show packages corresponding to the preamble of claim 1.

La présente invention a pour but de pallier ces inconvénients en proposant un plateau en matière en feuille de carton, un ensemble de flans, un dispositif et un procédé permettant de fabriquer un tel plateau, répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'elle propose un plateau facilement gerbable, en trois éléments dont deux éléments latéraux forment des poutres latérales, chacun muni d'un rabat de collage sur le fond du troisième élément.The object of the present invention is to overcome these drawbacks by proposing a board made of cardboard sheet material, a set of blanks, a device and a method making it possible to manufacture such a board, which responds better than those previously known to the requirements of the practice. in particular in that it proposes an easily stackable tray, in three elements, two side elements of which form lateral beams, each provided with a glue flap on the bottom of the third element.

Un tel plateau est tolérant aux défauts de géométrie, sans pour autant que cela soit préjudiciable à sa RCV.Such a plate is tolerant to geometry defects, without this being detrimental to its RCV.

Chacun des trois éléments va pouvoir être orienté et dimensionné, en grammage et en épaisseur de cannelure, de façon à optimiser sa fonction, à savoir soit la résistance en compression verticale soit la résistance au flambage.Each of the three elements will be able to be oriented and dimensioned, in grammage and groove thickness, so as to optimize its function, namely either the vertical compressive strength or the buckling resistance.

Dans la suite de la description des figures on utilisera les mêmes numéros de référence pour désigner des éléments identiques ou similaires.In the remainder of the description of the figures, the same reference numbers will be used to designate identical or similar elements.

Les figures 1 à 3 montrent deux plateaux 1 superposés parallélépipédiques, identiques, en matière en feuille de carton, selon un premier mode de réalisation de l'invention.The Figures 1 to 3 show two parallel parallelepipedal superposed plates 1, made of cardboard sheet material, according to a first embodiment of the invention.

Chaque plateau 1 est formé de trois pièces séparées 2, 3 et 4 à savoir une première pièce 2 formant un fond 5 relié par des premières lignes de pliage 6 à deux premières parois latérales 7 et deux deuxièmes pièces 3 et 4 formant deux deuxièmes parois latérales opposées 8 et 9 comportant chacune un premier rabat longitudinal 10, 11 relié à ladite deuxième paroi 8, 9 par une deuxième ligne de pliage 12, 13 avantageusement légèrement décalée pour permettre la compensation des épaisseurs de carton, au moins en partie, et collé sur la face inférieure du fond 5.Each plate 1 is formed of three separate pieces 2, 3 and 4, namely a first piece 2 forming a bottom 5 connected by first fold lines 6 to two first side walls 7 and two second pieces 3 and 4 forming two second side walls. opposed 8 and 9 each having a first longitudinal flap 10, 11 connected to said second wall 8, 9 by a second fold line 12, 13 advantageously slightly offset to allow compensation of the cardboard thicknesses, at least in part, and bonded to the bottom face of the bottom 5.

Chaque deuxième paroi 8, 9 comprend deux jeux de rabats transversaux 14, 15 comportant chacun au moins un rabat transversal 16 respectivement collé sur la face interne d'une première paroi latérale correspondante 7 en vis à vis.Each second wall 8, 9 comprises two sets of transverse flaps 14, 15 each comprising at least one transverse flap 16 respectively bonded to the inner face of a first corresponding side wall 7 facing each other.

Plus précisément, sur le plateau représenté sur les figures 1 à 3 et en référence également aux figures 4A, 4B et 6A, 6B, chaque jeu de rabats 14, 15 comprend un premier rabat transversal 17 relié à la deuxième paroi latérale 8, 9 correspondante par une troisième ligne de pliage 18 et collé sur la face interne de la première paroi latérale adjacente.More precisely, on the plateau represented on the Figures 1 to 3 and also with reference to Figures 4A, 4B and 6A, 6B each set of flaps 14, 15 comprises a first transverse flap 17 connected to the corresponding second side wall 8, 9 by a third fold line 18 and adhered to the inner face of the first adjacent side wall.

Chaque jeu de rabats 14, 15 comprend de plus des deuxièmes rabats transversaux rectangulaires 20 reliés par une quatrième ligne de pliage 21 audit premier rabat transversal (cf. figures 3, 4A et 6A), lesdits deuxième rabats transversaux étant chacun eux-mêmes reliés par une cinquième ligne de pliage 23 (parallèle à la deuxième ligne de pliage)à un troisième rabat transversal 24 coopérant avec la face interne 25 des deuxièmes parois en vis à vis pour former un pilier 22 (voir figure 4A) de coin d'angle du plateau.Each set of flaps 14, 15 further comprises second transverse rectangular flaps 20 connected by a fourth fold line 21 to said first transverse flap (cf. figures 3 , 4A and 6A ), said second transverse flaps being each themselves connected by a fifth fold line 23 (parallel to the second fold line) to a third transverse flap 24 cooperating with the inner face 25 of the second walls facing to form a pillar 22 (see Figure 4A ) Corner corner of the tray.

Comme représenté sur la figure 3 on voit par ailleurs que le premier rabat 11 est agencé pour venir s'encastrer entre les parties supérieures 26 des jeux de rabats transversaux 14, 15 formant pilier d'angle.As shown on the figure 3 it is also seen that the first flap 11 is arranged to fit between the upper portions 26 sets of transverse flaps 14, 15 forming corner pillar.

Cet encastrement provient notamment du fait que les rabats 10 et 11 étant collés sur le fond 3 du plateau du dessus viennent en excroissance par rapport au fond ce qui permet donc un emboitement avec la périphérie supérieure des piliers, tout en autorisant un auto-centrage et un blocage de façon latérale d'un plateau sur l'autre.This embedding is due in particular to the fact that the flaps 10 and 11 being bonded to the bottom 3 of the top plate come into protrusion with respect to the bottom, which therefore allows interlocking with the upper periphery of the pillars, while allowing self-centering and a lateral blocking of one tray on the other.

On comprend donc que l'existence de ces rabats, collés sur la face externe inférieure du fond permet un excellent gerbage des plateaux les uns sur les autres.It is therefore understood that the existence of these flaps, glued to the lower outer face of the bottom allows an excellent stacking trays on each other.

Plus précisément et toujours en référence aux figures 4A et 6A on remarque que les deux pièces 3, 4 sont obtenues à partir d'une même découpe 27 (cf. figure 6A) symétrique par rapport à une ligne de découpe 28.More precisely and always with reference to Figures 4A and 6A it is noted that the two parts 3, 4 are obtained from the same cut 27 (cf. Figure 6A ) symmetrical with respect to a cutting line 28.

Les premiers rabats longitudinaux 10, 11 sont de forme sensiblement trapézoïdale, la petite base étant formée par la deuxième ligne de pliage 12, 13 et la grande base étant elle-même de dimension inférieure à la longueur totale de la deuxième paroi (8,9) à laquelle le premier rabat 10, 11 est rattaché, les côtés latéraux respectifs 28 dudit premier rabat étant par exemple en forme de nez pour permettre l'encastrement par leur forme complémentaire avec l'espacement entre les piliers du plateau du dessous.The first longitudinal flaps 10, 11 are of substantially trapezoidal shape, the small base being formed by the second fold line 12, 13 and the large base itself being smaller than the total length of the second wall (8, 9 ) to which the first flap 10, 11 is attached, the respective lateral sides 28 of said first flap being for example nose-shaped to allow embedding by their complementary shape with the spacing between the pillars of the tray below.

Un évidement 29 entre les deux premiers rabats 10, 11 accolés, symétriques par rapport à la ligne de découpe 28 de forme oblongue, est avantageusement prévu.A recess 29 between the two first flaps 10, 11 contiguous, symmetrical with respect to the cutting line 28 of oblong shape, is advantageously provided.

Les figures 4B et 6B montrent une variante de réalisation des deuxièmes pièces, qui comportent de plus sur le bord périphérique externe 30 des deuxièmes parois, deux languettes triangulaires ou trapézoïdales 31 dirigées vers l'extérieur et reliées respectivement par des lignes de pliage 32 à chaque extrémité de ladite périphérie des deuxièmes parois.The Figures 4B and 6B show an alternative embodiment of the second parts, which furthermore comprise on the outer peripheral edge 30 second walls, two triangular or trapezoidal tongues 31 directed outwards and respectively connected by fold lines 32 at each end of said periphery of the second walls.

Les languettes 31 sont elles-mêmes prolongées latéralement par une petite languette rectangulaire 34 située à l'aplomb du premier rabat transversal 17 et qui permet (cf. figure 4B) lorsque la deuxième paroi est constituée avec ses.piliers d'angle, de venir recouvrir la face externe 35 du premier rabat transversal 17 permettant ainsi une consolidation de l'ensemble.The tongues 31 are themselves laterally extended by a small rectangular tongue 34 located directly above the first transverse flap 17 and which allows (cf. Figure 4B ) when the second wall is formed with its corner pillars, to cover the outer face 35 of the first transverse flap 17 thus allowing consolidation of the assembly.

Selon le mode de réalisation des figures 4B, 6A, 6B, on a de plus représenté sensiblement centré sur chaque deuxième paroi 8, 9 un trou oblong 36 obtenu par découpe permettant la préhension du plateau.According to the embodiment of Figures 4B , 6A, 6B , there is also shown substantially centered on each second wall 8, 9 an oblong hole 36 obtained by cutting for gripping the plate.

On a représenté sur les figures 5A à 5C et 7A à 7C trois modes de réalisation de premières pièces utilisables avec l'invention.We have shown on FIGS. 5A to 5C and 7A to 7C three embodiments of first parts used with the invention.

Les figures 5A et 7A montrent un flan 37 comportant un fond rectangulaire 5 et deux premières parois latérales opposées reliées audit fond par les lignes de pliage 6 à savoir une première paroi rectangulaire verticale 38 de la hauteur du plateau et une première paroi 39 en forme de U, comportant un évidement central 40.The Figures 5A and 7A show a blank 37 having a rectangular bottom 5 and two opposite first side walls connected to said bottom by the fold lines 6 namely a first vertical rectangular wall 38 of the height of the plate and a first U-shaped wall 39, having a recess central 40.

Dans d'autres modes de réalisation (figures 5B et 7B) la première pièce 41 de fond comprend une première paroi 42 de hauteur plus petite que la paroi en vis à vis 38, ce qui permet une ouverture latérale du plateau, ou au contraire deux parois 7 de même hauteur (cf. figures 1 à 3).In other embodiments ( Figures 5B and 7B ) the first piece 41 of bottom comprises a first wall 42 of smaller height than the facing wall 38, which allows a lateral opening of the plate, or on the contrary two walls 7 of the same height (cf. Figures 1 to 3 ).

Enfin dans un autre mode de réalisation de premières pièces 43 et en référence aux figures 5C et 7C, il est prévu une première paroi 44 munie d'une languette d'arrachage 45 figurée en trait interrompu sur la figure 7C, permettant d'ouvrir le plateau d'un côté pour avoir accès par exemple à son contenu.Finally, in another embodiment of first pieces 43 and with reference to Figures 5C and 7C , there is provided a first wall 44 provided with a pull tab 45 shown in broken lines on the Figure 7C , to open the tray on one side to access for example its contents.

On a représenté sur les figures 8A et 8B deux autres modes de réalisation de plateaux 46 et 47 selon l'invention, et sur les figures 9A et 9B les découpes 48, 49 pour deuxièmes pièces correspondances.We have shown on Figures 8A and 8B two other embodiments of trays 46 and 47 according to the invention, and on the Figures 9A and 9B the cutouts 48, 49 for second pieces of correspondence.

Plus précisément la figure 8A montre un plateau 46 dont les deux premières parois latérales 50 sont de hauteur plus petite que celles des secondes parois latérales 51.More specifically figure 8A shows a plate 46 whose first two side walls 50 are of smaller height than those of the second side walls 51.

Celles-ci comportent quant à elles sur leur périphérie supérieure 52 des deuxièmes rabats longitudinaux 53 propres à former des trottoirs horizontaux rectangulaires, et comportant de chaque côté deux petites languettes latérales 54 carrées, rabattues sur la face externe du premier rabat transversal 56 correspondant de la deuxième paroi concernée.These comprise on their upper periphery 52 second longitudinal flaps 53 capable of forming horizontal horizontal sidewalks, and having on each side two small lateral tabs 54 square, folded on the outer face of the first transverse flap 56 corresponding to the second wall concerned.

Les figures 8B et 9B montrent quant à elles, un plateau 47 avec élément d'angle 57 formé par deux petites languettes 58 du type de celles décrites en référence à la figure 6B. Des petites encoches 59 dans la périphérie supérieure 60 des premiers rabats transversaux sont prévues pour éviter les surchappements.The Figures 8B and 9B show in turn, a plate 47 with corner element 57 formed by two small tabs 58 of the type described in reference to the Figure 6B . Small notches 59 in the upper periphery 60 of the first transverse flaps are provided to prevent overfalls.

Ces éléments vont notamment permettre l'encastrement avec les premiers rabats en vis à vis en excroissance par rapport au fond du plateau.These elements will notably allow the embedding with the first flaps in opposite protruding relative to the bottom of the plate.

Dans le mode de réalisation des figures 8A et 8B, le dessus des trottoirs 53 comportent un évidement 62, où encore un espacement entre éléments d'angle 57, de forme complémentaire avec la forme des premiers rabats en excroissance, pour permettre l'encastrement.In the embodiment of Figures 8A and 8B , the top of the sidewalks 53 comprise a recess 62, where yet a spacing between corner elements 57, of complementary shape with the shape of the first protruding flaps, to allow embedding.

On a représenté sur les figures 10A, 10B, 10C et 11 un autre mode de réalisation d'un plateau 63 selon l'invention, qui comporte ici encore des trottoirs 64 en partie supérieure formés par des deuxièmes rabats rectangulaires longitudinaux 65 reliés à la périphérie 66 supérieure longitudinale des deuxièmes parois rectangulaires 67 et les premiers rabats transversaux 68 comportant quant à eux des petites languettes triangulaires 69 refermées et collées sur le dessus du rabat formant trottoir décrit ci-avant.We have shown on FIGS. 10A, 10B, 10C and 11 another embodiment of a plate 63 according to the invention, which here again comprises sidewalks 64 in the upper part formed by second rectangular longitudinal flaps 65 connected to the upper longitudinal periphery 66 of the second rectangular walls 67 and the first transverse flaps 68 having in turn small triangular tabs 69 closed and glued on top of the sidewalk flap described above.

L'encastrement est ici possible entre ces deux petites languettes triangulaires 69 et le premier rabat de forme complémentaire.The embedding is here possible between these two small triangular tabs 69 and the first flap of complementary shape.

Les figures 12 et 15 montrent en perspective et en plan deux autres modes de réalisation de deuxièmes parois 70 et 71 selon l'invention, comportant deux premiers rabats transversaux 72 reliés à deux seconds rabats transversaux 73, ces modes de réalisation permettant un collage à l'intérieur d'une première pièce 74 du type de la figure 13, rectangulaire, comportant elle-même deux premières parois rectangulaires 75 munies à chacune de leurs extrémités respectives d'une languette 76 également rectangulaire, les deuxièmes parois 71 de la figure 15 étant donc agencées de telle sorte que leur deuxième rabat 73 soit collé sur les faces internes 77 des premières parois de l'emballage.The Figures 12 and 15 show in perspective and in plan two other embodiments of second walls 70 and 71 according to the invention, comprising two first transverse flaps 72 connected to two second transverse flaps 73, these embodiments allowing a bonding inside a first piece 74 of the type of the figure 13 , rectangular, itself comprising two first rectangular walls 75 provided at each of their respective ends with a tongue also rectangular 76, the second walls 71 of the figure 15 being so arranged that their second flap 73 is glued on the inner faces 77 of the first walls of the package.

Dans un autre mode de réalisation (figure 14) la première pièce 78 comporte un fond 79 octogonal et chaque première paroi 80 comprend des languettes d'extrémité 81. Les deuxièmes parois 71 sont alors collées sur cette première pièce de telle sorte que on forme un plateau 82 à huit côtés, les premiers rabats transversaux 72 étant eux-mêmes collés sur les languettes d'extrémité 81 des premières parois 80 de la première pièce.In another embodiment ( figure 14 ) the first part 78 has an octagonal bottom 79 and each first wall 80 comprises end tongues 81. The second walls 71 are then glued on this first part so that a plate 82 is formed with eight sides, the first flaps transverse 72 being themselves glued on the end tabs 81 of the first walls 80 of the first part.

Les figures 17 à 19 montrent les flans pour deuxièmes pièces (figure 17) et premières pièces (figures 18 et 19) permettant de réaliser les éléments respectivement des figures 12 et 15 et 13 et 16.The Figures 17 to 19 show the blanks for second pieces ( figure 17 ) and first pieces ( Figures 18 and 19 ) to realize the elements respectively of the Figures 12 and 15 and 13 and 16 .

On a représenté sur les figures 20A à 21 d'autres modes de réalisation de premières pièces 81 et deuxièmes pièces 82 selon l'invention, permettant de constituer un plateau tronconique 83 à parois 84 inclinées vers l'intérieur, (ou l'extérieur) favorisant l'empilage.We have shown on Figures 20A to 21 other embodiments of first parts 81 and second parts 82 according to the invention, for forming a frustoconical plate 83 with walls 84 inclined inwardly, (or outside) favoring the stacking.

Plus précisément il est proposé un flan 85 formé de deux deuxièmes pièces 82 symétriques par rapport à un axe central 86 comprenant des deuxièmes parois 87 rectangulaires munies du premier rabat longitudinal 10, 11 du type de ceux décrit en référence aux figures précédentes et de part et d'autre deux rabats transversaux 88 de forme trapézoïdale, à savoir comportant un premier côté 89 constitué par la ligne de pliage et relié à son deuxième côté périphérique externe 90 par deux côtés parallèles 91 inclinés vers l'extérieur, du côté opposé au premier rabat longitudinal 10, 11.More specifically, it is proposed a blank 85 formed of two second parts 82 symmetrical with respect to a central axis 86 comprising second rectangular walls 87 provided with the first longitudinal flap 10, 11 of the type described with reference to the preceding figures and from other two transverse flaps 88 of trapezoidal shape, namely having a first side 89 constituted by the fold line and connected to its second outer peripheral side 90 by two parallel sides 91 inclined outwards, the opposite side to the first flap longitudinal 10, 11.

La première pièce quant à elle est alors formée d'un fond rectangulaire 92 muni des deux premières parois 93 qui comportent elles-mêmes des côtés latéraux 94 en biais vers l'intérieur pour former des trapèzes isocèles dont le petit côté 95 et formé par le bord périphérique externe.The first part, for its part, is then formed of a rectangular bottom 92 provided with the first two walls 93 which themselves have lateral sides 94 sloping inwards to form isosceles trapezes whose short side 95 and formed by the outer peripheral edge.

Ces bords supérieurs 96 des deuxièmes parois 87 comprennent des encoches 97 aptes à s'encastrer dans les bords 98 des rabats longitudinaux 10 et 11 en surchappement.These upper edges 96 of the second walls 87 comprise notches 97 able to fit in the edges 98 of the longitudinal flaps 10 and 11 in the form of an escapement.

On a représenté sur les figures 23 à 25 un autre mode de réalisation de l'invention. La première pièce (figure 23B) est quant à elle formée par des flans similaires à ceux décrits en référence aux figures 7A à 7C.We have shown on Figures 23 to 25 another embodiment of the invention. The first piece ( Figure 23B ) is formed by blanks similar to those described with reference to Figures 7A to 7C .

Le deuxième flan 99 permettant de fabriquer les deuxièmes parois est quant à lui formé symétriquement de part et d'autre d'une ligne de séparation 100, par un premier volet rectangulaire 101 muni en son centre d'une ligne de pliage autour de laquelle sont situées de part et d'autre et symétriquement, deux lignes de pliage parallèles 103 puis la troisième ligne de pliage 104 de rattachement aux premiers volets transversaux 105, la périphérie supérieure externe de cette deuxième paroi comportant de plus des languettes 106 du type décrit en référence à la figure 9B ou 6B.The second blank 99 making it possible to manufacture the second walls is itself formed symmetrically on either side of a dividing line 100, by a first rectangular flap 101 provided at its center with a fold line around which are located on either side and symmetrically, two parallel fold lines 103 and the third folding line 104 for attachment to the first transverse flaps 105, the outer upper periphery of this second wall further comprising tabs 106 of the type described with reference to the Figure 9B or 6B .

Les deuxièmes parois, une fois séparées par rapport à leur ligne de jonction (cf figure 24) sont pliées de façon à ce que la partie centrale 107 vienne former un triangle isocèle, la dimension de la deuxième paroi, une fois froncée en son milieu, étant égale à la longueur de la première paroi.The second walls, once separated from their junction line (cf. figure 24 ) are folded so that the central portion 107 comes to form an isosceles triangle, the size of the second wall, once gathered in the middle, being equal to the length of the first wall.

Le plateau 108 est ensuite constitué de façon similaire aux emballages précédents.The plate 108 is then formed similarly to the previous packages.

On va maintenant décrire plus précisément en référence aux figures 26A à 26G, le procédé de fabrication d'un plateau selon un mode de réalisation de l'invention, du type décrit en référence aux figures 1 à 3 et 4A et 5C.We will now describe more precisely with reference to Figures 26A to 26G , the method of manufacturing a tray according to one embodiment of the invention, of the type described with reference to Figures 1 to 3 and 4A and 5C .

A partir de deux flans de matière en feuille de carton ondulé à savoir un premier flan F formé d'un fond 5 relié par des premières lignes de pliage 6 à deux premières parois latérales 7 opposées et un deuxième flan 27 propre à former deux deuxièmes parois 8, 9 latérales opposées, identiques et symétriques par rapport à la ligne de séparation 28, chaque deuxième paroi latérale comportant au moins un premier rabat 10, 11 longitudinal relié d'un côté à une deuxième paroi correspondante 8, 9 par une deuxième ligne de pliage 12 et de l'autre côté par ladite ligne de séparation 28 à la périphérie externe de l'autre premier rabat longitudinal de la deuxième paroi latérale symétrique en vis à vis, et deux jeux de rabats transversaux 14, 15 comportant chacun au moins un rabat transversal 24, on découpe (étape 110) le deuxième flan au niveau de la ligne de séparation 28 pour former les deux deuxièmes pièces.From two blanks of corrugated sheet material, namely a first blank F formed of a bottom 5 connected by first fold lines 6 to two first and opposite side walls 7 and a second blank 27 to form two second walls 8, 9 opposite sides, identical and symmetrical with respect to the line of separation 28, each second lateral wall comprising at least one first flap 10, 11 longitudinal connected on one side to a second corresponding wall 8, 9 by a second line of folding 12 and on the other side by said dividing line 28 at the outer periphery of the other first longitudinal flap of the second symmetrical side wall opposite, and two sets of transverse flaps 14, 15 each having at least one transverse flap 24, the second blank is cut (step 110) at the separation line 28 to form the two second pieces.

On transfère ensuite (flèche 111) les deux deuxièmes pièces à un poste d'assemblage 112 en encollant au passage les faces internes des parois 8, 9 et les rabats 10, 11 et 24 avec de la colle dite « hot melt » de façon connue en elle-même.Then transfer (arrow 111) the two second parts to an assembly station 112 by gluing the passage of the inner faces of the walls 8, 9 and the flaps 10, 11 and 24 with the so-called hot melt glue in a known manner in herself.

Puis on transfère (flèche 114) le premier flan F de sa pile de stockage vertical 115 à niveau constant, que l'on vient plaquer sur les rabats 10 et 11 comme montré à la figure 26B. Les transferts se font latéralement par ventouse.Then the first blank F of its vertical storage stack 115 is transferred (arrow 114) to a constant level, which is pressed onto the flaps 10 and 11 as shown in the figure 26B . Transfers are laterally by suction cup.

Puis on amène (flèche 116) des éléments 117 qui vont permettre le pliage des piliers d'angle et qui seront décrits plus précisément ci-après en référence au dispositif.Then (arrow 116) is brought elements 117 which will allow the folding of the corner pillars and which will be described more precisely below with reference to the device.

En référence aux figures 26C et 26D on plie (flèches 118 et 119) les jeux de rabats 14 et 15 vers les deuxièmes parois encollées (cf. figure 26D) puis, (cf figure 26E) après retrait (flèche 120) des éléments 117, on transfère (flèche 121 de la figure 26E) l'ensemble de flans ainsi constitué à un poste 122 de formage pour l'enrouler (flèche 123 cf. figure 26F) autour d'un mandrin 124 à huit cotés pour former le plateau 125 (cf. figure 26G).With reference to Figures 26C and 26D the flap sets 14 and 15 are bent (arrows 118 and 119) towards the second sized walls (cf. figure 26D ) then, (cf figure 26E ) after removal (arrow 120) of the elements 117, is transferred (arrow 121 of the figure 26E ) the set of blanks thus formed at a forming station 122 for winding (arrow 123 cf. figure 26F ) around an eight-sided mandrel 124 to form the plate 125 (cf. figure 26G ).

Les figures 27A et 27b montrent les étapes principales d'un mode de réalisation différent du procédé selon l'invention utilisant un mandrin rétractable 127 du type connu en lui-même par exemple comprenant quatre taquets 128 déplaçables entre une position écartée (figure 27A) et une position rétractée (figure 27B) pour extraction (flèche 129) permettant d'échapper les rebords 57 des plateaux 47 du type décrit en référence à la figure 8B et/ou les trottoirs en référence à la figure 8A.The Figures 27A and 27b show the main steps of a different embodiment of the method according to the invention using a retractable mandrel 127 of the type known in itself, for example comprising four cleats 128 movable between a remote position ( Figure 27A ) and a retracted position ( Figure 27B ) for extraction (arrow 129) to escape the flanges 57 of the trays 47 of the type described with reference to the Figure 8B and / or sidewalks with reference to the figure 8A .

On a représenté maintenant en référence aux figures 28 à 32 un dispositif 130 de formation d'un plateau selon le mode de réalisation de l'invention plus particulièrement décrit ici.We have now shown with reference to Figures 28 to 32 a device 130 for forming a plate according to the embodiment of the invention more particularly described here.

Le dispositif comprend deux magasins de stockage 131 et 132 des premiers flans F et deuxièmes flans 27 lesdits magasins étant formés par des chariots élévateurs sur lesquels les flans sont calés et empilés à plat, le chariot montant au fur et à mesure du dépilement.The device comprises two storage magazines 131 and 132 of the first blanks F and second blanks 27, said magazines being formed by forklifts on which the blanks are wedged and piled flat, the carriage rising as and when unfolding.

Le magasin de stockage des deuxièmes flans est par ailleurs muni d'une lame de découpe (non représentée) du deuxième flan de façon symétrique au niveau de la ligne de séparation 28 en deux.The storage magazine of the second blanks is also provided with a cutting blade (not shown) of the second blank symmetrically at the separation line 28 in two.

Deux bras d'extraction 133 et 134 (cf. figures 28 et 30) formés par des pistons et munis de ventouses 135 d'aspiration permettent la désolidarisation d'un des flans par rapport à l'autre, leur écartement et leur transfert au poste d'assemblage 136 avec encollage par des moyens 137 connus en eux-mêmes.Two extraction arms 133 and 134 (cf. figures 28 and 30 ) formed by pistons and provided with suction cups 135 allow the separation of one of the blanks relative to the other, their spacing and their transfer to the assembly station 136 with gluing by means 137 known in themselves .

Le premier flan F est quant à lui amené latéralement par l'intermédiaire d'un chariot 138 au poste d'assemblage comprenant une bande 139 de transfert.The first blank F is brought laterally via a carriage 138 to the assembly station comprising a transfer band 139.

Plus précisément, en référence à la figure 28, le magasin de séparation des deuxièmes parois latérales comprend un chariot 140 d'amené au poste d'assemblage, montré sur une poutre 140' reposant de part et d'autre sur deux chemins de roulement 140".More specifically, with reference to the figure 28 the separation magazine of the second side walls comprises a carriage 140 brought to the assembly station, shown on a beam 140 'resting on both sides on two tracks 140 ".

Il comporte les deux bras 133, 134 de mise en position en largeur. Ce chariot d'amené est actionné par une courroie d'entrainement 141 pour le transfert au poste d'assemblage.It comprises the two arms 133, 134 of position in width. This feeder carriage is actuated by a drive belt 141 for transfer to the assembly station.

Au passage des deuxièmes flans les moyens d'encollage 137 des flans pour assemblage sont prévus.At the passage of the second blanks the sizing means 137 blanks for assembly are provided.

Ils sont par exemple formés de pistolets d'encollage connus en eux-mêmes.They are for example formed of glue guns known in themselves.

Un taquet de transfert (non représenté) aux différents postes permet une fois le flan en position sur la bande de transfert 139, la prise de l'ensemble ainsi calé pour l'amener au poste suivant.A transfer latch (not shown) at the various positions allows once the blank in position on the transfer band 139, taking the set and wedged to bring it to the next station.

Le dispositif 130 comporte par ailleurs un poste 142 de formation des dièdres ou piliers d'angles, et plus particulièrement un système de mise en forme et en pression des dièdres comprenant des pistons 143 et un chariot 144 de descente d'une pièce comportant des dièdres 145 conformés pour mise en contrepression.The device 130 furthermore includes a dihedral or corner pillar formation station 142, and more particularly a dihedral shaped and pressure forming system comprising pistons 143 and a dihedral descent truck 144 comprising 145 shaped for counterpressure.

Un système 146 de pliage à 90° des dièdres par piston pousseur est par ailleurs prévu, les chariots 148 d'amené des poutres 149 de section transversale triangulaire de formation des dièdres de façon motorisée étant par ailleurs prévus en dessous du poste de formation.A system 146 for folding the dihedrals by pusher piston is also provided, the carriages 148 for bringing the beams 149 of triangular cross-section for forming the dihedrons in a motorized manner are also provided below the training station.

Des pistolets d'encollage avant mise en volume réglables par glissière sont positionnés de façon adéquate, un système (non représenté) de pliage vertical du type décrit en référence à la figure 32 étant par ailleurs prévu.Slide-adjustable volume-sizing glue guns are conveniently positioned, a vertical folding system (not shown) of the type described with reference to FIG. figure 32 being otherwise planned.

Il comporte ainsi des bras verticaux 150 arrondis en partie supérieure pour faciliter l'accostage et repousser les rabats verticaux.It thus has vertical arms 150 rounded at the top to facilitate docking and push the vertical flaps.

Une fois les poutres formées, les chariots 148 d'amenée des poutres 149 de formation des dièdres sont retirés et l'ensemble est poussé par l'intermédiaire de la bande 139 vers le poste de formation 151 autour du mandrin 152.Once the beams are formed, the carriages 148 for feeding the dihedral forming beams 149 are removed and the assembly is pushed through the band 139 to the training station 151 around the mandrel 152.

Ici encore, des pistolets d'encollage (non représentés), avant mise en volume, sont prévus de façon connue en elle-même, ainsi qu'un système 153 de pliage et de pressage du fond réglable en deux directions par système de vis.Here again, sizing guns (not shown), before setting volume, are provided in a manner known per se, and a system 153 for folding and pressing the bottom adjustable in two directions by screw system.

Le système 153 est agencé pour venir plaquer les parois verticales du plateau sur les faces latérales du mandrin 152 amené par le haut.The system 153 is arranged to press the vertical walls of the plate on the lateral faces of the mandrel 152 brought from above.

A noter que celui-ci peut être changé au niveau du format.Note that this one can be changed at the format level.

Le système 153 comprend un équipage 154 agencé pour se déplacer entre une position basse 155 d'échappement des lames verticales 156 à extrémité courbe horizontale 156' et une position haute 157 de plaquage de lames sur les parois 8 et 9 d'une part et 7 d'autre part pour collage avec les faces externes des piliers d'angles 14, 15.The system 153 comprises a crew 154 arranged to move between a low position 155 of exhaust of the vertical blades 156 with horizontal curved end 156 'and a high position 157 of blade plating on the walls 8 and 9 on the one hand and 7 on the other hand for bonding with the external faces of the corner pillars 14, 15.

On va maintenant décrire le fonctionnement du dispositif selon le mode de réalisation de l'invention plus particulièrement précisé ici.We will now describe the operation of the device according to the embodiment of the invention more particularly specified here.

On dépile les deuxièmes pièces ou découpes d'extrémité une à une à partir du magasin 132 à niveau constant.The second pieces or end cuttings are removed one by one from the constant level magazine 132.

Les deux bords périphériques des deux premiers rabats longitudinaux 10 et 11 étant liés par des points d'attache, le dépilage est assuré par les deux systèmes représentés à la figure 30 pilotés et équipés de ventouses, une par extrémité.The two peripheral edges of the first two longitudinal flaps 10 and 11 being linked by attachment points, unstacking is provided by the two systems shown in FIG. figure 30 piloted and equipped with suction cups, one per end.

Le point haut de chaque dépileur est différent ce qui permet de libérer les points d'attache et de séparer de ce fait les deux deuxièmes pièces ou découpes d'extrémité distinctes.The top point of each unstacker is different which allows to release the attachment points and thereby separate the two second pieces or separate end cutouts.

Ces découpes d'extrémité sont transférées au poste de jonctionnement 136, et pendant ce transfert les panneaux de liaison sont encollés et mis en position en largueur par les deux chariots embarqués indépendants 140 pilotés par des cerveaux moteurs.These end cutouts are transferred to the junction station 136, and during this transfer the connecting panels are glued and placed in position in width by the two independent truck trolleys 140 driven by motor brains.

Les extrémités sont alors mis en place au poste de jonctionnement qui comporte une bande transporteuse 139.The ends are then put in place at the junction station which comprises a conveyor belt 139.

Pendant le même temps une découpe de fond et/ou première pièce est extraite à partir du magasin à niveau constant 131.During the same time, a bottom cut and / or first piece is extracted from the constant level magazine 131.

Le transfert de la découpe de fond se fait au poste de jonctionnement par l'intermédiaire d'un chariot 138 également piloté par cerveaux moteurs.The transfer of the bottom cutout is done at the junction station via a carriage 138 also driven by motor brains.

Durant ce transfert un système de collage embarqué dépose la colle nécessaire à la création des dièdres des extrémités.During this transfer an embedded gluing system deposits the glue necessary for the creation of the dihedrons of the extremities.

Il y ensuite une mise en pression du fond sur les extrémités puis un transfert de l'ensemble au poste de formation des dièdres.Then there is a pressurization of the bottom on the ends and a transfer of the assembly to the training station of the dihedrons.

Le poste 146 de formation des dièdres comprend la mise en place de quatre contre-formes correspondant à la dimension des dièdres (deux systèmes droit et gauche motorisés par cerveaux moteurs).The dihedral formation station 146 comprises the establishment of four counter-forms corresponding to the dimension of the dihedrons (two right and left systems powered by motor brains).

Puis il y a mise à la vertical des dièdres autour de leur rainant (ligne de pliage) par une rampe et mise à l'horizontal des dièdres autour de leur rainants complémentaires par système dynamique et enfin mise en forme et en pression des dièdres autour des rainants suivants par un outillage comportant des pistons 143 puis ensuite un retrait des contre-formes.Then there is placed vertically dihedrons around their raining (fold line) by a ramp and horizontal dihedrons around their complementary rainings by dynamic system and finally formatting and pressure of the dihedrons around the following grooves by a tool having pistons 143 and then a retreat against the forms.

Ensuite le transfert au poste de mise en volume est effectué.Then the transfer to the volume setting station is performed.

Durant ce transfert le fond est encollé.During this transfer the bottom is glued.

On réalise alors la mise en volume du plateau par descente du mandrin (interne) sur le plateau à plat et mise à la vertical des extrémités des parois 8 et 9, puis des panneaux 7 du fond, avant mise en pression du plateau puis une éjection.The volume is then made to volume by lowering the (internal) mandrel on the flat plate and placing the ends of the walls 8 and 9, then panels 7 of the bottom, before pressurizing the plate and ejection.

A noter que dans les cas où les extrémités sont équipées de trottoirs totaux ou partiels ils sont formés au poste de mise en volume, le mandrin interne étant alors rétractable pour permettre son dégagement.Note that in cases where the ends are equipped with total or partial sidewalks they are formed at the volume setting station, the inner mandrel then being retractable to allow its release.

Sur les figures 33 et 34, on a représenté une portion de plateau 160 comprenant un fond rectangulaire 161 relié par les premières lignes de pliage 162 à deux premières parois sensiblement rectangulaires 163. Le plateau comprend de plus deux deuxièmes parois latérales 164 rectangulaires (une seule est représentée sur la figure) comprenant un rabat longitudinal 165 rectangulaire, relié à ladite deuxième paroi par une deuxième ligne de pliage 166, de façon centrée sur une partie de la longueur de la paroi par exemple les 2/3 ou les 4/5, et collé sur la face externe 167 du fond, et deux rabats transversaux 168 collés sur la face interne 169 des premières parois 163 en vis à vis.On the Figures 33 and 34 , there is shown a plateau portion 160 comprising a rectangular bottom 161 connected by the first fold lines 162 to two substantially rectangular first walls 163. The plate further comprises two second rectangular side walls 164 (only one is shown in the figure) comprising a longitudinal flap 165 rectangular, connected to said second wall by a second fold line 166, centrally on a part of the length of the wall for example the 2/3 or 4/5, and glued on the outer face 167 of the bottom, and two transverse flaps 168 bonded to the inner face 169 of the first walls 163 opposite.

Comme on le voit sur les figures la zone de carton du fond au niveau de la deuxième ligne de pliage est divisée en trois parties à savoir une zone centrale 170 en vis à vis du rabat longitudinal 165 et deux zones 171 situées de part et d'autre entre les bords du rabat et les premières parois.As seen in the figures, the cardboard zone of the bottom at the level of the second folding line is divided into three parts, namely a central zone 170 facing the longitudinal flap 165 and two zones 171 located on the side and side. other between the edges of the flap and the first walls.

Afin de limiter au maximum la surépaisseur du rabat collé sur le dessous du fond au niveau de la zone 170 et formé de sorte que le fond se déforme verticalement pour permettre à la bordure du rabat de s'aligner avec les bordures franches 172 des zones 171, il est prévu des zones 173, sensiblement rectangulaires en forme de languette le long ou au bord d'une partie de la première ligne de pliage, par exemple de largeur égale à la moitié de celle de la zone 171 et de longueur suffisante pour obtenir une bonne élasticité, par exemple quelques centimètres en fonction de l'épaisseur du carton.In order to minimize the extra thickness of the flap glued to the bottom of the bottom at the area 170 and formed so that the bottom deforms vertically to allow the edge of the flap to align with the fringes 172 of the areas 171 zones 173 are provided, substantially rectangular tab-shaped along or at the edge of a portion of the first fold line, for example of a width equal to half that of the area 171 and of sufficient length to obtain good elasticity, for example a few centimeters in function of the thickness of the carton.

Cet écrasement localisé du carton aux extrémités du fond autorise ainsi un léger bombement (voir figure 35, flèche 174) de sorte que les points d'appui de la paroi verticale sur les zones 171 sont alignés avec ceux de la zone 170. Ainsi l'ensemble des parois verticales formées par les premières parois et les deuxièmes parois participent de façon similaire à la compression, augmentant significativement la RCV.This localized crushing of the cardboard at the ends of the bottom thus allows a slight bulge (see figure 35 , arrow 174) so that the points of support of the vertical wall on the zones 171 are aligned with those of the zone 170. Thus all the vertical walls formed by the first walls and the second walls participate similarly to compression, significantly increasing the RCV.

On a représenté sur les figures 35 à 39, les éléments partiels, en perspective, en cours de formation, ou formés, d'un plateau 175 selon un autre mode de réalisation de l'invention.We have shown on Figures 35 to 39 , the partial elements, in perspective, being formed, or formed, a plate 175 according to another embodiment of the invention.

La figure 35 montre un fond 161 du type de celui décrit à la figure 33.The figure 35 shows a bottom 161 of the type described in figure 33 .

La figure 36 montre en perspective le fond 161 et un demi flan 176. Le demi flan 176 permettant d'obtenir les deuxièmes parois latérales comprend une deuxième paroi rectangulaire 177, munie du rabat longitudinal 178, propre à être collé sur le fond, en forme de languette, de deux rabats rectangulaires latéraux 179 de part et d'autre, et de l'autre côté d'un bord externe 180, formant une ligne de pliage, de jonction 181, avec un troisième volet rectangulaire 182 de longueur égale à celle des rabats 179, par exemple de longueur égale au 1/3 de la longueur des premières parois latérales 163, muni de deux rabats rectangulaires 183, 184 propres à être rabattus sur les rabats 179 pour former les trottoirs 185 (cf figure 38).The figure 36 shows in perspective the bottom 161 and a half-blank 176. The half-blank 176 for obtaining the second side walls comprises a second rectangular wall 177, provided with the longitudinal flap 178, adapted to be glued to the bottom, in the form of a tongue, two lateral rectangular flaps 179 on either side, and on the other side of an outer edge 180, forming a junction fold line 181, with a third rectangular flap 182 of equal length to that of the flaps 179 , for example of length equal to 1/3 of the length of the first side walls 163, provided with two rectangular flaps 183, 184 adapted to be folded over the flaps 179 to form the sidewalks 185 (cf. figure 38 ).

Des évidements 186 au niveau des lignes de pliage 181, dans le volet 182 de forme complémentaire aux languettes 178, pour permettre l'encastrement, sont prévus.Recesses 186 at the fold lines 181, in the flap 182 of complementary shape to the tabs 178, to allow embedding, are provided.

Dans un mode de réalisation représenté en traits mixtes sur la figure 37, le volet 182 est remplacé par un volet 187 propre à former le dessus du plateau et à se refermer par une languette 188 sur la deuxième paroi 189 en vis à vis.In an embodiment shown in phantom on the figure 37 , the flap 182 is replaced by a flap 187 to form the top of the plate and to close by a tab 188 on the second wall 189 facing.

Comme il va de soi et comme il résulte d'ailleurs de ce qui précède la présente invention ne se limite pas aux modes de réalisation plus particulièrement décrits. Elle en embrasse au contraire toutes les variantes et notamment celles où les flans des premières parois latérales et du fond est de fort grammage, par exemple 100g/m2, et celui des deuxièmes parois et de faible grammage par exemple inférieur à 50g/m2, celles où le poste de formage est différent, la formation du plateau se faisant par pistonnage de façon connue en elle-même, ou d'autres manières n'utilisant pas de mandrin, celles où les zones écrasées latérales permettant le bombement, sont remplacées par une zone écrasée centrale, la languette 178 étant alors située par exemple à l'intérieur de la boîte, collée sur la face interne du fond.It goes without saying and as it follows from the foregoing the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all the variants and in particular those in which the blanks of the first side walls and of the bottom are of heavy weight, for example 100 g / m 2 , and that of the second walls and of low grammage, for example less than 50 g / m 2 those where the forming station is different, the formation of the plate being done by pistons in a manner known per se, or in other ways not using a mandrel, those where the crushed lateral areas allowing bulging, are replaced by a central crushed area, the tongue 178 then being located for example inside the box, glued on the inner face of the bottom.
