Description

La présente invention concerne un flan en matière en feuille de carton pour la réalisation d'au moins un croisillon destiné à subdiviser un contenant-récipient en plusieurs compartiments, le flan comportant plusieurs volets articulés qui, par pliage, sont susceptibles de former une partie des compartiments.The present invention relates to a blank made of cardboard sheet material for producing at least one cross for dividing a container-container into several compartments, the blank comprising a plurality of articulated flaps which, by folding, are capable of forming part of compartments.

Elle concerne également un procédé et une machine pour la réalisation de tels croisillons ainsi que les croisillons obtenus.It also relates to a method and a machine for producing such braces as well as braces obtained.

Elle trouve une application particulièrement importante bien que non exclusive dans le domaine de l'emballage modulable de bouteilles ainsi isolées par de tels croisillons.It finds a particularly important, although not exclusive, application in the field of modular packaging of bottles thus isolated by such braces.

Elle est également applicable à tous types de produits qu'ils soient ronds, carrés ou en sachets. Par modulable, on entend le fait de pouvoir, avec le même type de flan, prévoir des groupages de produits de façon modulaire et multiple. Ainsi, avec les mêmes flans accolés et multipliés par deux, trois, quatre, cinq, il est possible de grouper trois, six, douze, quinze bouteilles etc...It is also applicable to all types of products whether they are round, square or in bags. By modular means the fact of being able, with the same type of blank, to provide groupings of products in a modular and multiple way. Thus, with the same flanks contiguous and multiplied by two, three, four, five, it is possible to group three, six, twelve, fifteen bottles, etc.

On connaît déjà des croisillons constitués de parois croisées selon deux directions orthogonales. Ces croisillons sont réalisés en général à partir de plusieurs flans de carton pourvus de fentes et assemblés pour former les parois des croisillons.Braces consisting of walls crossed in two orthogonal directions are already known. These braces are generally made from several cardboard blanks provided with slots and assembled to form the walls of the braces.

Ils présentent cependant des inconvénients. En effet, il est nécessaire de prévoir au moins deux sortes de flans différents, une pour les parois longitudinales et une autre pour les parois transversales, ce qui complique fabrication et montage. Il est ensuite nécessaire d'assembler les flans entre eux, ce qui présente des inconvénients de coût et de durée de montage.However, they have disadvantages. Indeed, it is necessary to provide at least two different types of blanks, one for the longitudinal walls and another for the transverse walls, which complicates manufacture and assembly. It is then necessary to assemble the blanks together, which has disadvantages of cost and installation time.

On connaît également ( EP 0 332 538 ) des flans d'une seule pièce.We also know ( EP 0 332 538 ) blanks in one piece.

Si de tels flans permettent d'éviter certains inconvénients des croisillons en plusieurs pièces, grâce notamment à un système de soufflets, ceux-ci sont source de surépaisseur et d'instabilité dimensionnelle des croisillons, du fait de leur élasticité.If such blanks make it possible to avoid certain disadvantages of the braces in several parts, thanks in particular to a system of bellows, these are source of overthickness and dimensional instability of the braces, because of their elasticity.

On connaît également un flan d'une seule pièce en matière en feuille qui comporte deux ensembles de volets articulés séparables. Chaque ensemble est susceptible de former une partie des compartiments des croisillons ainsi qu'un panneau intermédiaire, relié aux deux ensembles des volets qui, après séparation, permet de constituer les croisillons.There is also known a blank of a single piece made of sheet material which comprises two sets of separable hinged flaps. Each set is capable of forming a portion of the compartments of the braces and an intermediate panel, connected to the two sets of flaps which, after separation, allows to form the braces.

Un tel flan présente cependant des difficultés de montage et se révèle, ici encore, assez complexe à mettre en oeuvre.Such a blank, however, has mounting difficulties and is again, here again, quite complex to implement.

Tous ces flans sont, dès le départ, structurellement conçus et dimensionnés pour un seul nombre de produits à conditionner. En d'autres termes, ils ne sont pas modulables.All these blanks are, from the outset, structurally designed and sized for a single number of products to be packaged. In other words, they are not scalable.

On connaît également ( FR 2 806 063 ; FR 2 618 312 ; FR 2 869 294 ; GB 2 259 691 ; FR 2 766 792 ) des croisillons en carton pour caisse de bouteilles. Tous ces croisillons sont également destinés à un nombre de bouteilles déterminé, préalablement établi et sont de montage à imbrications compliquées.We also know ( FR 2 806 063 ; FR 2,618,312 ; FR 2 869 294 ; GB 2,259,691 ; FR 2,766,792 ) cardboard braces for bottle cases. All these braces are also intended for a number determined bottles, previously established and are complicated nesting assembly.

La présente invention vise à fournir un flan, un procédé, une machine et un croisillon répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'elle va permettre un transport sans dommage dans une caisse en carton ondulé de récipients notamment en verre, et ce de façon modulaire. Avec un même flan selon l'invention, il devient possible d'assurer de façon modulable, la protection de groupements de produits en nombre variable, de deux à quarante-huit produits par exemple.The present invention aims to provide a blank, a method, a machine and a cross respond better than those previously known to the requirements of practice, particularly in that it will allow a transport without damage in a cardboard box corrugated containers including glass, and this modular way. With the same blank according to the invention, it becomes possible to provide modular protection of groups of products in variable numbers, from two to forty-eight products for example.

En d'autres termes, pour un format de flan donné, de section hauteur et géométrie déterminées et ce, que les produits soient de section ronde ou rectangulaire, il est possible d'insérer un ou plusieurs modules de base d'un même type, éventuellement complétés par une surface séparatrice verticale, selon le nombre de produits à regrouper dans la caisse correspondante sélectionnée.In other words, for a given blank format, of determined height and geometry section, whether the products are of round or rectangular section, it is possible to insert one or more basic modules of the same type, possibly supplemented by a vertical separating surface, according to the number of products to be grouped in the corresponding box selected.

L'invention permet ainsi, pour un format donné de produits de réaliser de très nombreuses combinaisons de groupage différent, en limitant les nombres de références de flan de carton requis.The invention thus makes it possible, for a given product format, to produce a very large number of different grouping combinations, by limiting the numbers of cardboard blank references required.

Par exemple et selon le module de base sélectionné correspondant à deux bouteilles, trois bouteilles, quatre bouteilles, cinq bouteilles ou six bouteilles, il devient possible de prévoir le compte en multiples de ces nombres, en créant respectivement, jusqu'à huit compartiments ou cavités, quinze cavités, vingt cavités, vingt cinq cavités, trente cavités etc....For example, and depending on the selected basic module corresponding to two bottles, three bottles, four bottles, five bottles or six bottles, it becomes possible to predict the count in multiples of these numbers, respectively creating up to eight compartments or cavities , fifteen cavities, twenty cavities, twenty five cavities, thirty cavities, etc.

Grâce à cette notion de modules de base, qui vont ensuite pouvoir être réutilisés les uns à côté des autres, parallèlement ou après retournement, avec ou sans plaque séparatrice, les possibilités de croisillonage de caisses deviennent très nombreuses pour un coût optimisé, compte tenu notamment de cette standardisation.Thanks to this concept of basic modules, which will then be reused next to each other, parallel or after reversal, with or without separator plate, the possibilities of cross-check crates become very numerous for an optimized cost, especially given of this standardization.

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

La figure 1 montre un flan 1 en matière en feuille de carton, par exemple en carton ondulé de 3 mm d'épaisseur, pour la réalisation du croisillon 2 de la figure 2.The figure 1 shows a blank 1 made of cardboard sheet material, for example made of 3 mm corrugated cardboard thickness, for the realization of the spider 2 of the figure 2 .

Le flan 1 comprend un premier volet 3 carré, propre à former le fond du croisillon, relié sur un côté par une première ligne de pliage 4 à un deuxième volet 5 sensiblement rectangulaire, propre à former une paroi intermédiaire entre deux compartiments 6.The blank 1 comprises a first square flap 3, suitable for forming the bottom of the spider, connected on one side by a first fold line 4 to a second substantially rectangular flap 5 capable of forming an intermediate wall between two compartments 6.

Le deuxième volet 5 comprend un premier ergot 7 de verrouillage situé à l'extrémité extérieure de son côté 9 adjacent à la première ligne de pliage 4.The second flap 5 comprises a first locking pin 7 located at the outer end of its side 9 adjacent to the first fold line 4.

Le flan 1 comprend de plus un troisième volet 10 relié en premier volet par une deuxième ligne de pliage 11 adjacente et perpendiculaire à la première, et situé du côté correspondant à l'ergot. Le troisième volet 10 est sensiblement rectangulaire et est muni d'une première languette 12 ajourée par un orifice oblong 13, réalisé dans un évidement rectangulaire 14 pratiqué au centre du bord externe du troisième volet, opposé au premier volet.The blank 1 further comprises a third flap 10 connected in first flap by a second folding line 11 adjacent and perpendicular to the first, and located on the side corresponding to the lug. The third flap 10 is substantially rectangular and is provided with a first tongue 12 perforated by an oblong orifice 13, made in a rectangular recess 14 made in the center of the outer edge of the third flap, opposite to the first flap.

La languette 12 est reliée au reste du troisième volet 10 en partie basse de l'évidement 14 par une ligne de pliage 15 sur laquelle l'orifice 13 est en partie à cheval.The tongue 12 is connected to the remainder of the third flap 10 in the lower part of the recess 14 by a fold line 15 on which the orifice 13 is partly astride.

L'ergot 7 est quant à lui réalisé sur le côté 9 du deuxième volet 5 situé du côté du troisième volet 10, et constitue l'un des angles d'un évidement 16, par exemple sensiblement carré, formé dans le coin dudit deuxième volet 5.The lug 7 is made on the side 9 of the second flap 5 located on the side of the third flap 10, and constitutes one of the corners of a recess 16, for example substantially square, formed in the corner of said second flap 5.

Cet évidement va permettre l'encastrement de la languette ou plus exactement de son extrémité 17, qui vient également se coincer à sa périphérie supérieure dans une petite encoche 18, formée à l'angle de l'évidement 16 adjacent à l'ergot 7.This recess will allow the recessing of the tongue or, more accurately, its end 17, which is also jammed at its upper periphery in a small notch 18, formed at the angle of the recess 16 adjacent to the stub 7.

Enfin le troisième volet 10 présente une dimension longitudinale ou longueur hors tout l, supérieure à la somme des longueurs l 1 et l 2 des premier et deuxième volets, par exemple d'un dixième de la longueur l.Finally, the third flap 10 has a longitudinal dimension or overall length l greater than the sum of the lengths l 1 and l 2 of the first and second flaps, for example one tenth of the length l .

Le troisième volet 10 comprend des côtés latéraux 19 qui sont en partie haute perpendiculaires à la périphérie externe 20 dudit volet, et en partie basse, c'est-à-dire situé du côté de la ligne de pliage 11, en biais vers ladite ligne de pliage, formant ainsi des angles qui vont permettre de faciliter un encastrement dans l'emballage.The third flap 10 comprises lateral sides 19 which are in the upper part perpendicular to the outer periphery 20 of said flap, and in the lower part, that is to say situated on the side of the fold line 11, obliquely towards said line. folding, thus forming angles that will facilitate an embedding in the package.

De la même façon, le côté latéral 21 du deuxième volet 5 situé du côté opposé à l'ergot 7 par rapport au volet, est formé d'une première partie 22 perpendiculaire au côté d'extrémité externe 23 du deuxième volet, et une deuxième partie en biais 24 vers la première ligne de pliage 4, qui présente ainsi également une forme en biseau, facilitant ici encore l'introduction pour l'encastrage du croisillon dans la boîte.Similarly, the lateral side 21 of the second flap 5 located on the opposite side to the lug 7 relative to the flap, is formed of a first portion 22 perpendicular to the outer end side 23 of the second flap, and a second biased portion 24 to the first fold line 4, which thus also has a beveled shape, again facilitating the introduction for embedding the cross in the box.

Les dimensions respectives de ces différents volets sont pour le troisième volet une longueur hors tout l plus petite à la base par exemple de 0,8l.The respective dimensions of these different components are for the third component a length overall l smaller at the base for example 0.8 l .

Le premier volet est par exemple et quant à lui carré d'une longueur et largeur égale à l 1, le deuxième volet étant pour sa part d'une longueur l 2 égale à la largeur du troisième volet et d'une largeur hors tout la plus grande égale à la moitié de la longueur du troisième volet soit 1/2.The first component is for example and meanwhile square of a length and width equal to 1, the second flap being for its part with a length l 2 equal to the width of the third panel and an overall width of the greater equal to half the length of the third flap is 1/2.

On a représenté sur la figure 3 un flan 25 selon un deuxième mode de réalisation de l'invention propre à former un module croisillon 26 représenté sur la figure 4.We have shown on the figure 3 a blank 25 according to a second embodiment of the invention itself to form a cross-section module 26 shown on the figure 4 .

Le flan 25 comprend un volet 27 par exemple rectangulaire propre à former le fond du croisillon 26, relié sur un côté par une première ligne de pliage 4 à un deuxième volet 5 du type décrit en référence à la figure 1.The blank 25 comprises a flap 27, for example rectangular, capable of forming the bottom of the spider 26, connected on one side by a first fold line 4 to a second flap 5 of the type described with reference to FIG. figure 1 .

Il comporte de l'autre côté opposé et symétrique par rapport à un axe central 28 de symétrie transversale du flan, un quatrième volet 29 relié au premier volet 27 par une troisième ligne de pliage 30, ledit quatrième volet étant donc lui aussi sensiblement carré ou rectangulaire comme le deuxième volet 4 et propre à former une deuxième paroi intermédiaire 29 entre deux desdits compartiments 6.It comprises on the opposite side and symmetrical with respect to a central axis 28 of transverse symmetry of the blank, a fourth flap 29 connected to the first flap 27 by a third fold line 30, said fourth flap thus also being substantially square or rectangular like the second flap 4 and adapted to form a second intermediate wall 29 between two of said compartments 6.

Le quatrième volet 29 comporte une deuxième ergot 31, symétrique du premier ergot 7 du deuxième volet 5 par rapport à l'axe central 28 de symétrie.The fourth component 29 comprises a second lug 31, symmetrical with the first lug 7 of the second louver 5 with respect to the central axis 28 of symmetry.

Le deuxième ergot 31 de verrouillage est situé à l'extrémité extérieure 32 du côté adjacent 33 à la troisième ligne de pliage 30.The second locking pin 31 is located at the outer end 32 of the adjacent side 33 at the third fold line 30.

Le flan 25 comporte par ailleurs un troisième volet central 34 sensiblement rectangulaire muni de deux languettes 35 ajourées identiques, du type de la languette 12 décrite en référence à la figure 1, et agencée pour se verrouiller avec les premier et deuxième ergots tout en venant s'encastrer dans les évidements 18,36 des premiers et troisièmes volets afin de réaliser le croisillon 26.The blank 25 also comprises a third substantially rectangular central flap 34 provided with two identical perforated tongues 35, of the type of the tongue 12 described with reference to FIG. figure 1 , and arranged to lock with the first and second lugs while being embedded in the recesses 18,36 of the first and third flaps to achieve the spider 26.

On a représenté sur la figure 3A une plaque de carton ondulé qui va permettre de constituer les flans 25, 25' permettant d'obtenir les croisillons de la figure 4. Sur la figure 4A on a représenté deux croisillons juxtaposés l'un à l'autre 26, 26', le croisillon 26' reposant respectivement sur les bords 21, 37 de l'extrémité des deuxième et quatrième volets 5 et 29 du croisillon 26.We have shown on the figure 3A a corrugated cardboard plate which will make it possible to form the blanks 25, 25 'making it possible to obtain the crosspieces of the figure 4 . On the Figure 4A there are two braces juxtaposed to each other 26, 26 ', the spider 26' resting respectively on the edges 21, 37 of the end of the second and fourth flaps 5 and 29 of the spider 26.

La figure 4B montre quant à elle trois croisillons 26, 26', 26" disposés à la queue leu leu. Le croisillon 26" peut être inversé de façon à présenter des compartiments ouverts 38 vers l'extérieur de part et d'autre.The Figure 4B shows, in turn, three braces 26, 26 ', 26 "arranged in a single file, the spider 26" can be inverted so as to have open compartments 38 outwardly on either side.

On a représenté sur la figure 4C deux jeux de croisillons 26, 26', avant le retournement du croisillon 26', en vis-à-vis de deux emballages à huit côtés de type connu. La figure 4D montre quant à elle les croisillons mis en place à l'intérieur des emballages après retournement des croisillons 26', ce qui permet de situer les ouvertures 38 vers l'extérieur, autorisant les coins coupés 40 à épouser la forme des bouteilles en angle (cf. figure 4D).We have shown on the figure 4C two sets of braces 26, 26 ', before the turning of the spider 26', vis-à-vis two packages with eight sides of known type. The figure 4D shows in turn the braces placed inside the packages after turning spiders 26 ', which allows to locate the openings 38 to the outside, allowing the cut corners 40 to match the shape of the bottles at an angle (cf. . figure 4D ).

La figure 5 montre un troisième mode de réalisation d'un flan 42 selon l'invention.The figure 5 shows a third embodiment of a blank 42 according to the invention.

Ici le flan comporte un premier volet 43 rectangulaire relié par une première ligne de pliage 44 à un deuxième volet 45 d'un côté et sur le côté opposé par une troisième ligne de pliage 46 à un quatrième volet 47, ledit quatrième volet étant symétrique du premier volet par rapport à un axe de symétrie 48 du flan, axe perpendiculaire à la dimension transversale des premier, deuxième et quatrième volets.Here the blank comprises a first rectangular flap 43 connected by a first fold line 44 to a second flap 45 on one side and on the opposite side by a third fold line 46 to a fourth flap 47, said fourth flap being symmetrical with first flap with respect to an axis of symmetry 48 of the blank, axis perpendicular to the transverse dimension of the first, second and fourth flaps.

Le flan 42 comprend de plus un troisième volet principal 49 sensiblement rectangulaire comprenant des bords latéraux 50 dirigés du côté du premier volet, en biais vers les premier volet, le troisième volet principal étant relié audit premier volet par une deuxième ligne de pliage 51 au côté adjacent aux premières et troisièmes lignes de pliage 44 et 46. Le troisième volet principal est d'une longueur hors tout L inférieure à la longueur hors tout L' de la suite des premier, deuxième et quatrième volets.The blank 42 further comprises a third substantially rectangular main flap 49 comprising lateral edges 50 directed towards the first flap, biased towards the first flap, the third flap main flap being connected to said first flap by a second fold line 51 adjacent to the first and third fold lines 44 and 46. The third main flap is of overall length L less than the overall length L 'of the following the first, second and fourth parts.

Chacun des deuxième et quatrième volets est muni d'une encoche 52, symétrique de l'autre par rapport à l'axe central 48, lesdites encoches étant disposées au droit des première et troisième lignes de pliage 44 et 46.Each of the second and fourth flaps is provided with a notch 52, symmetrical to the other with respect to the central axis 48, said notches being arranged at the right of the first and third fold lines 44 and 46.

Plus précisément, ces encoches sont formées par un orifice 53 pratiqué dans une languette 54 réalisée dans un évidement par exemple rectangulaire 55 dans le troisième volet. La hauteur à laquelle se trouve cette encoche, lorsque la languette est dressée perpendiculairement au volet 49, correspond à celle des ergots ou crochets 56 appartenant respectivement au premier volet 45 et au quatrième volet 47 situés du côté du troisième volet.More specifically, these notches are formed by an orifice 53 formed in a tongue 54 made in a recess, for example rectangular 55 in the third flap. The height at which this notch is, when the tongue is erected perpendicularly to the flap 49, corresponds to that of the lugs or hooks 56 respectively belonging to the first flap 45 and fourth flap 47 located on the side of the third flap.

Ces crochets sont agencés pour s'encliquer dans les évidements 53, une fois la languette repliée vers le haut à horizontale.These hooks are arranged to engage in the recesses 53, once the tongue folded upwards horizontally.

Plus précisément, les crochets 56 sont formés par un évidement adéquat 57 du carton, à l'angle 58 du volet en carton correspondant, dirigé vers l'extérieur.Specifically, the hooks 56 are formed by a suitable recess 57 of the carton, at the corner 58 of the corresponding cardboard flap, directed outwards.

Une petite rainure 59 dans le fond de l'évidement permet par ailleurs l'encliquetage et le blocage de l'extrémité 60 de la languette 54 lorsque le croisillon 61 est formé, comme montré en référence à la figure 6.A small groove 59 in the bottom of the recess also allows snapping and locking the end 60 of the tongue 54 when the spider 61 is formed, as shown with reference to the figure 6 .

Dans le mode de réalisation plus particulièrement décrit ici en référence à la figure 5, chacun des premier et quatrième volets comporte de plus une encoche 62 perpendiculaire aux lignes de pliage 44 ou 46, et pratiquée au centre ou sensiblement au centre du côté externe d'extrémité 63 desdits volets, lesdites encoches 62 étant propres à coopérer avec une plaque séparatrice 64 (cf. figure 5A), elle-même munie d'encoches 65 propres à s'insérer dans les encoches 62, lorsque la plaque est mise en place. Les encoches 62, 65 sont par exemple terminées à leur extrémité externe par des ouvertures en V permettant une meilleure introduction et guidage de l'une dans l'autre, avant blocage.In the embodiment more particularly described here with reference to the figure 5 , each of the first and fourth flaps further comprises a notch 62 perpendicular to the fold lines 44 or 46, and made centrally or substantially at the center of the outer end side 63 of said flaps, said notches 62 being adapted to cooperate with a plate separator 64 (cf. Figure 5A ), itself provided with notches 65 adapted to fit into the notches 62, when the plate is put in place. The notches 62, 65 are for example terminated at their outer end by V-shaped openings for better introduction and guiding of the one into the other, before blocking.

On a représenté sur les figures 6B, 6C et 6D l'utilisation de tels ensembles 61, 64 ; 61', 64', à l'extérieur d'un emballage (figure 6B), à l'intérieur d'un emballage 67 rectangulaire, avant introduction des plaques séparatrices 64, 64', (figure 6C) et après remplissage par des produits 68 qui présentent ici des formes rectangulaires (figure 6D).We have shown on Figures 6B, 6C and 6D the use of such sets 61, 64; 61 ', 64', on the outside of a package ( Figure 6B ), inside a rectangular packaging 67, before introduction of the separating plates 64, 64 ', ( Figure 6C ) and after filling with products 68 which here have rectangular shapes ( Figure 6D ).

Dans les modes de réalisation des figures 6, 6A, 6B, 6C, et 6D, et pour pouvoir avoir des emplacements ouverts du côté des parois internes de la caisse 67, l'ensemble de flans 61, 64 a été retourné pour être mis tête bêche avec l'ensemble de flans 61', 64', comme montré par la flèche 69 sur la figure 6B.In the embodiments of FIGS. 6, 6A, 6B, 6C, and 6D , and to be able to have open locations on the side of the inner walls of the box 67, the set of blanks 61, 64 has been turned over to be turned upside down with the set of blanks 61 ', 64', as shown by FIG. arrow 69 on the Figure 6B .

Il s'agît ici d'un exemple de groupage réalisé à partir d'un module de trois alvéoles pour bouteilles rectangulaires, permettant d'obtenir très simplement et instantanément un croisillon de douze alvéoles, grâce à deux plaques séparatrices.This is an example of grouping made from a module of three cells for rectangular bottles, to obtain very simply and instantly a cross of twelve cells, thanks to two separator plates.

On a représenté sur la figure 7 un autre mode de réalisation d'un flan 70 muni d'un premier volet 71 rectangulaire, d'un deuxième volet et d'un quatrième volet 72 et 73 reliés de part et d'autre au premier volet par des premières et troisièmes lignes de pliage comme décrit ci-avant en référence à la figure 3, et munis d'ergots du type décrit en référence à la même figure sur leurs extrémités 18.We have shown on the figure 7 another embodiment of a blank 70 provided with a first rectangular flap 71, a second flap and a fourth flap 72 and 73 connected on either side to the first flap by first and third lines of folding as described above with reference to the figure 3 , and provided with lugs of the type described with reference to the same figure on their ends 18.

Le troisième volet central 74 comprend quant à lui, de façon similaire au volet 34 de la figure 3,deux languettes 35.The third central component 74, for its part, similarly to the component 34 of the figure 3 two tabs 35.

Dans ce mode de réalisation, elles sont séparées sur l'axe central transversal 28 de l'emballage, par une encoche 75, par exemple terminée par une petite fente en forme de petit crochet 76.In this embodiment, they are separated on the transverse central axis 28 of the package, by a notch 75, for example terminated by a small slot in the form of a small hook 76.

Cette petite fente ou coupure située en partie inférieure, à l'extrémité de l'encoche 75, permet un meilleur accrochage de la plaque séparatrice prévue pour compléter le croisillon. Il s'agit par exemple de la plaque 77 de la figure 7A, qui pourrait être utilisée sur une série de cinq ou six croisillons chacun obtenu avec le flan 70 de la figure 7.This small slot or cut located in the lower part, at the end of the notch 75, allows better attachment of the splitter plate provided to complete the cross. This is for example the plate 77 of the Figure 7A , which could be used on a series of five or six braces each obtained with the blank 70 of the figure 7 .

Cette plaque séparatrice est quant à elle, munie d'encoches 78 agencées pour coopérer avec les encoches 75 du flan de la figure 7, encoches elles aussi pourvues des coupures en forme de petits crochets 76.This separating plate is provided with notches 78 arranged to cooperate with the notches 75 of the blank of the figure 7 notches also provided with cuts in the form of small hooks 76.

On a représenté sur la figure 8A le résultat du croisillon 79 obtenu avec les différents jeux de flans de la figure 7. Comme montré sur la figure 8 la plaque séparatrice centrale 77, est introduite par le dessus et les rend solidaires les uns avec les autres. L'ensemble peut ensuite être inséré dans un emballage de dimension adéquate.We have shown on the figure 8A the result of the cross 79 obtained with the different sets of blanks of the figure 7 . As shown on the figure 8 the central separating plate 77 is introduced from above and makes them integral with each other. other. The assembly can then be inserted in a package of adequate size.

Les figures 9, 10 et 11 montrent des exemples de groupages réalisables à partir de modules de base tels que décrits ci-avant avec quatre alvéoles (figure 9) cinq alvéoles (figure 10) et six alvéoles (figure 11).The Figures 9, 10 and 11 show examples of groupings that can be made from basic modules as described above with four cells ( figure 9 ) five cells ( figure 10 ) and six cells ( figure 11 ).

A partir du module 80 correspondant au flan de la figure 7, muni d'une encoche centrale 75, et de la plaque séparatrice 77, on obtient un croisillon de vingt bouteilles rondes, par l'utilisation de cinq modules et d'une plaque séparatrice.From the module 80 corresponding to the blank of the figure 7 , provided with a central notch 75, and the separator plate 77, a cross of twenty round bottles is obtained by the use of five modules and a separating plate.

A partir d'un module 81, muni de deux encoches 82 du type d'encoche 75, on obtient un croisillon de trente bouteilles rondes, par exemple avec six modules 81 plus deux plaques séparatrices 77.From a module 81, provided with two notches 82 of the notch type 75, a brace of thirty round bottles is obtained, for example with six modules 81 plus two separating plates 77.

Enfin, à partir d'un croisillon 83 muni de trois encoches 84 réparties régulièrement entre les languettes 35 et correspondant aux encoches 82 et 75, on obtient un croisillon 86 de trente six bouteilles rondes, en utilisant ici six modules 83, plus trois plaques séparatrices 77.Finally, from a spider 83 provided with three notches 84 regularly distributed between the tongues 35 and corresponding to the notches 82 and 75, a spider 86 of thirty six round bottles is obtained, using here six modules 83, plus three separating plates. 77.

On a représenté sur les figures 12A et 12B deux modes de réalisation de plaques 90 et 91 permettant d'obtenir des flans 25, 25' et 25", 25"' du type décrits en référence à la figure 3. Dans un premier cas (plaque 90) les flans sont disposés pour être découpés par une machine de découpe à plat de type connu, par exemple fabriquée par la société Suisse BOBST, à la suite les uns des autres. Dans une deuxième cas (plaque 91)deux de deux flans successifs sont placés tête bêche, de façon symétrique par rapport à un axe de symétrie transversale 92.We have shown on Figures 12A and 12B two embodiments of plates 90 and 91 for obtaining blanks 25, 25 'and 25 ", 25"' of the type described with reference to FIG. figure 3 . In a first case (plate 90) the blanks are arranged to be cut by a flat cutting machine of known type, for example manufactured by the Swiss company BOBST, following each other. In a second case (plate 91) two of two successive blanks are placed head to tail, symmetrically with respect to a transverse axis of symmetry 92.

Il apparaît que ces dispositions vont permettre d'économiser la consommation de carton.It appears that these provisions will save the consumption of cardboard.

On a représenté sur les figures 13A à 13K les principales étapes au procédé de fabrication de croisillons à partir de modules au type décrit en référence à la figure 12A. Les flans permettant d'obtenir les modules sont regroupés en panoplies permettant par exemple de découper deux groupes 101 de modules dans un même laize en plaque de carton, lesdits groupes étant reliés entre eux par des points d'attache qui peuvent rompre à la traction ou au cisaillementWe have shown on Figures 13A to 13K the main steps in the process of manufacturing braces from modules of the type described with reference to the figure 12A . The blanks making it possible to obtain the modules are grouped together in sets that make it possible, for example, to cut two groups 101 of modules in one and the same width in a cardboard plate, said groups being interconnected by attachment points which can break with traction or shear

Ici, il a par exemple, mais de façon nullement limitative, été choisi de prendre un groupe de quatre modules conformes à la figure 12A. Après séparation des flans livrés en panoplie, chaque flan de carton comportant deux à quatre modules liés entre eux par des points d'attache, par l'intermédiaire de lame métallique 100, on constitue deux groupes 101 de flans, qui sont eux-mêmes séparés entre eux, pour former les quatre lignes de flans 25, 25', 25" et 25"'.Here, for example, but in no way limiting, was chosen to take a group of four modules compliant with the figure 12A . After separation of blanks delivered in panoplie, each cardboard blank having two to four modules interconnected by attachment points, by means of metal blade 100, there are two groups 101 blanks, which are themselves separate between them, to form the four blank lines 25, 25 ', 25 "and 25"'.

Ceux-ci sont déplacés (flèche 102) sur les éléments de mise en formes ou postes de formation 103 de modules.These are moved (arrow 102) on the forming elements or training stations 103 of modules.

Ces éléments de mise en modules sont constitués par plusieurs postes en parallèle, le nombre de postes variant selon le nombre de flans souhaités.These setting elements in modules consist of several stations in parallel, the number of positions varying according to the number of blanks desired.

Dans le mode de réalisation de la figure 13, il y a quatre postes de mise en volume. Les premières étapes A et B permettent le dépilage, le découpage de façon connue en elle-même, et le transport 102 vers les postes de formation 103. La séparation des flans, peut se faire pendant le transfert, ou aux postes de formation suivant, (Etape C), par exemple, à la tête de transfert.In the embodiment of the figure 13 there are four volume positions. The first steps A and B allow the unstacking, the cutting in a manner known per se, and the transport 102 to the training stations 103. The separation of the blanks, can be done during the transfer, or at the following training stations, (Step C), for example, at the transfer head.

L'étape D est l'étape de formation par pistonnage en cavité et/ou remontée verticale des doigts 104 de pliage.Step D is the step of formation by cavity and / or vertical lift of the folding fingers 104.

Le flan commence à prendre alors sa configuration repliée.The blank begins to take its folded configuration.

Une fois les flans en position de croisillons (Etape E), est réalisée l'étape F de verrouillage des languettes 105 par les doigts mobiles 106. Puis lors de l'étape G, il y a retrait des doigts mobiles, les croisillons étant alors constitués et les languettes encastrées dans les ergots en 107.Once the blanks in the position of braces (Step E), is carried out the F-locking step of the tongues 105 by the movable fingers 106. Then in step G, there is withdrawal of the movable fingers, the braces being then constituted and the tabs embedded in the lugs in 107.

Dans le mode de réalisation décrit ici, une étape H de rotation (flèche 108) à 180° d'un ou plusieurs modules 25 et 25" est réalisée. Cette étape de rotation est par exemple effectuée par les moyens de préhension par ventouse agencés pour pivoter mécaniquement autour d'un axe de 180°.In the embodiment described here, a step H of rotation (arrow 108) at 180 ° of one or more modules 25 and 25 "is carried out.This rotation step is for example carried out by the suction gripping means arranged to rotate mechanically around an axis of 180 °.

Vient ensuite l'étape J. L'objectif ici est de pouvoir obtenir une symétrie du croisillon 109 pour insertion dans les caisses 110 (flèche 111) ce qui permet aussi d'éviter tout risque que la paroi verticale d'extrémité du dernier module vienne buter contre la paroi de la caisse.Then comes the step J. The objective here is to be able to obtain a symmetry of the spider 109 for insertion into the crates 110 (arrow 111) which also makes it possible to avoid any risk that the vertical end wall of the last module comes from abut against the wall of the box.

Les croisillons sont ensuite introduits dans les caisses 110 pour obtenir les caisses croisillonnées 112 à l'étape K.The braces are then introduced into the crates 110 to obtain the crisscross boxes 112 in step K.

De façon à mieux illustrer les étapes importantes du procédé selon l'invention, on les a représentées en perspective et en vue latérale sur les figures 14A à 14D.In order to better illustrate the important steps of the process according to the invention, they have been represented in perspective and in a side view on the Figures 14A to 14D .

Ces étapes importantes correspondent aux étapes C, D, F et J de la figure 13 ci-dessus décrite.These important steps correspond to steps C, D, F and J of the figure 13 above described.

Les flans 25, 25', repris de façon connue par des dispositifs à ventouses sont placés sur les éléments 103 (103') de formage.The blanks 25, 25 ', taken in known manner by suction cup devices are placed on the forming elements 103 (103').

Ceux-ci comprennent une partie centrale 113 (113') en forme de puits (cf. figure 14A).These comprise a central portion 113 (113 ') in the form of a well (cf. figure 14A ).

Une pièce 114 en forme de piston munie d'une plaque pousseuse 115 par exemple actionnée pneumatiquement en 116, est alors positionnée sur le fond 27 du flan 25 avec qui il a une forme complémentaire, et/ou plus petite.A piston-shaped piece 114 provided with a push plate 115, for example actuated pneumatically at 116, is then positioned on the bottom 27 of the blank 25 with which it has a complementary shape, and / or smaller.

La plaque est ici, et par exemple, amovible et peut être changée pour s'adapter aux dimensions du fond 27.The plate is here, and for example, removable and can be changed to fit the dimensions of the bottom 27.

Sur la figure 14B pour former le module, soit les plaques pousseuses sont descendues, soit les doigts latéraux 104 sont remontés, soit les deux, et ce pour former les parois des croisillons en mettant à la verticale les première et quatrième volets latéraux 5 et 29 (5' et 29') et le troisième volet 34, 34'.On the Figure 14B to form the module, either the push plates are lowered, or the lateral fingers 104 are raised, or both, and this to form the walls of the braces by putting vertically the first and fourth side flaps 5 and 29 (5 'and 29 ') and the third flap 34, 34'.

En 14C, les languettes 35 sont rabattues (flèche 117) sur les ergots 7, 31 par des doigts de rabattage (non représentés) permettant d'obtenir le croisillon 26, 26'.At 14C, the tongues 35 are folded (arrow 117) on the pins 7, 31 by folding fingers (not shown) to obtain the spider 26, 26 '.

Puis l'ensemble 118 de pistonnage/rabattage est désactivée et/ou déplacé pour laisser accès aux moyens 119 de levage, préhension et déplacement des croisillons 26, 26' vers les boîtes à croisillons.Then the 118 piston / hinge assembly is deactivated and / or moved to allow access to the means 119 for lifting, gripping and moving the braces 26, 26 'to the cross boxes.

Sur les figures 15A et 15B, on a montré deux modes de réalisation de boîtes avec croisillons selon l'invention.On the Figures 15A and 15B two embodiments of boxes with braces according to the invention have been shown.

Dans le premier (figure 15A), on insère les croisillons 120 sans rotation à 180° d'au moins un des modules, (26, 26', 26", 26"') adaptable ainsi à une caisse rectangulaire 121.In the first ( figure 15A ), the braces 120 are inserted without 180 ° rotation of at least one of the modules, (26, 26 ', 26 ", 26"') thus adaptable to a rectangular box 121.

Dans le second, (figure 15B), il y a rotation d'au moins un des éléments 26, permettant d'avoir une ouverture 38 de chaque côté du croisillon 122, ce qui peut être tout particulièrement utilisé dans les caisses 123 à coins coupés 121.In the second, ( figure 15B ), there is rotation of at least one of the elements 26, to have an opening 38 on each side of the cross 122, which can be particularly used in crates 123 with cut corners 121.

On a représenté sur la figure 16 une machine 130 de fabrication automatique de croisillons à partir de feuilles de carton ondulé 91 séparées par lame, pour le compartimentage de boîtes, comprenant des moyens de stockage 131 d'au moins une pile de flans 133.We have shown on the figure 16 a machine 130 for manufacturing automatic braces from corrugated cardboard sheets 91 separated by a blade, for compartmentalizing boxes, comprising means 131 for storing at least one stack of blanks 133.

Il est par ailleurs prévu en 134 un magasin de plaques de séparation verticales 135.It is furthermore provided at 134 a vertical partition plate magazine 135.

Les flans sont par exemple des flans tels que décrits en référence à la figure 5.The blanks are for example blanks as described with reference to the figure 5 .

La machine 130 comprend des moyens 136 (schématisés en traits mixtes sur la figure 16) de préhension de type connu en eux mêmes, par exemple par ventouses 137 (cf. figure 18), par aspiration d'au moins un premier jeu de flans 138, des moyens 139 (cf. figure 17) de formation d'un module par pistonnage du premier volet et/ou remontée des doigts 103, 104, autour et/ou dans une cavité 113, relevant les deuxième et troisième quatrième volets.The machine 130 comprises means 136 (shown schematically in phantom on the figure 16 ) gripping type known in themselves, for example by suction cups 137 (cf. figure 18 ), by suction of at least a first set of blanks 138, means 139 (cf. figure 17 ) forming a module by swaging the first flap and / or raising of the fingers 103, 104 around and / or in a cavity 113, raising the second and third fourth flaps.

Ces moyens sont constitués de façon connue.These means are constituted in a known manner.

Les éléments (non représentés) pour verrouiller les ergots dans les languettes en vis-à-vis une fois le plan en volume, comportent par exemple des petits pistons permettant de repousser les languettes en les pliants sur les ergots.The elements (not shown) for locking the lugs in the tongues vis-à-vis once the plane in volume, include for example small pistons to push the tabs by folding on the lugs.

Des moyens 140 de préhension des modules 26, un par un et de transferts pour insertion dans des boîtes (non représentées) en 141 de façon connue en elle-même en suivant le trajet 142, pour évacuation des caisses croisillonées en 143.Means 140 for gripping the modules 26, one by one and transfers for insertion into boxes (not shown) at 141 in a manner known per se along the path 142, for evacuation of the cross boxes 143.

La figure 17 montre également schématiquement l'arrivée des flans 25, 25', 25", 25"' par exemple sous forme de plaque 91. Ceux-ci sont positionnés sur les moyens 103 de pistonnage, eux-mêmes disposés sur des rails 144 de guidage permettant de régler latéralement et horizontalement la dimension des pistons et des doigts de rabattage avant évacuation.The figure 17 also shows schematically the arrival of the blanks 25, 25 ', 25 ", 25"' for example in the form of plate 91. These are positioned on the piston means 103, themselves arranged on guide rails 144 allowing adjust laterally and horizontally the size of the plungers and the plucking fingers before evacuation.

La figure 18 montre quant à elle les éléments mécaniques qui viennent se superposer aux moyens pour pistonnage, et en particulier les moyens 138 de préhension des flans, conçus ici encore de façon connu en elle-même, et déplaçables horizontalement en X, Y, Z, pour venir appliquer les flans sur les puits par l'intermédiaire de vérins puis les évacuer vers les caisses une fois formés.The figure 18 shows in turn the mechanical elements that are superimposed on the means for pistons, and in particular the gripping means 138 blanks, here again designed in a known manner in itself, and horizontally movable X, Y, Z, to come apply the blanks to the wells by means of cylinders and then evacuate them to the crates once formed.

Comme il va de soi et comme il résulte également de ce qui précède, la présente invention n'est pas limitée aux modes de réalisation plus particulièrement décrits. Elle en embrasse au contraire toutes les variantes et notamment celles où les moyens d'accrochage des deuxième et quatrième volets sur le troisième volet sont différents.As is obvious and as also follows from the above, the present invention is not limited to the embodiments more particularly described. On the contrary, it encompasses all the variants and in particular those in which the attachment means of the second and fourth components on the third component are different.
