Description

La présente invention concerne un procédé et une machine pour la réalisation de croisillons destinés au compartimentage d'une ou plusieurs boítes, à partir d'un ensemble de flans en matière en feuille de carton ondulé, ainsi que le ou les croisillons obtenus à partir d'un tel procédé.The present invention relates to a method and a machine for making braces intended the compartmentalization of one or more boxes, from a set of blanks in sheet material of corrugated cardboard, as well as the brace obtained from such a process.

Elle trouve une application particulièrement importante bien que non exclusive dans le domaine des croisillons constitués de parois croisées selon deux directions, généralement orthogonales, permettant d'isoler des bouteilles disposées parallèlement dans un emballage.It finds a particularly application important although not exclusive in the field of cross-pieces consisting of walls crossed in two directions, usually orthogonal, allowing isolate bottles arranged parallel in a packaging.

On connaít déjà des croisillons pour emballages. Ils sont réalisés soit à partir d'un ensemble de plusieurs de flans de cartons pourvus de fentes et assemblés pour former les parois des croisillons, soit à partir de flans d'une seule pièce.We already know crosses for packaging. They are made either from a set of several cardboard blanks provided with slots and assembled to form the walls of the braces, either from one-piece blanks.

Dans le premier cas, il faut prévoir au moins deux types de flans différents, à savoir un pour les parois longitudinales, et un autre pour les parois transversales, ce qui complique la fabrication et le montage des croisillons, l'assemblage des flans entre eux s'étant toujours révélé jusqu'à présent long et coûteux. In the first case, at least two different types of blanks, namely one for longitudinal walls, and another for the walls transverse, which complicates the manufacturing and mounting the braces, assembling the blanks between them having always proved to be long and expensive.

Dans le second cas, c'est-à-dire le cas des croisillons obtenus à partir de flans d'une seule pièce, on évite les inconvénients des croisillons en plusieurs pièces.In the second case, that is to say the case of braces obtained from blanks of a single piece, we avoid the disadvantages of the cross Several pieces.

On connaít ainsi des croisillons mettant en oeuvre des soufflets qui s'escamotent lors de la formation du croisillon par pliage de volets.We thus know crosses implementing bellows that retract during training of the crosspiece by folding shutters.

Le principal inconvénient de ces croisillons réside ici dans les soufflets eux-mêmes, sources de surépaisseurs et d'instabilité du fait de leur élasticité.The main disadvantage of these braces resides here in the bellows themselves, sources of excess thickness and instability due to their elasticity.

Il y a ainsi difficulté à manipuler automatiquement les croisillons pour les introduire dans des emballages, difficulté encore aggravée dès que le nombre de compartiments du croisillon dépasse six du fait de la multiplication du nombre de soufflets.There is thus difficulty in handling automatically the crosspieces to introduce them in packaging, difficulty even worse from that the number of compartments of the cross exceeds six due to the multiplication of the number of bellows.

On connaít également (FR-A-2-628-397) des flans d'une seule pièce en une matière en feuille comportant d'une part deux ensembles de volets articulés, qui, par pliage, sont chacun susceptibles de former une partie des compartiments du croisillon, et d'autre part un panneau intermédiaire, relié aux deux ensembles de volets respectivement le long d'une ligne susceptible d'être rompue et le long d'une ligne susceptible de servir de ligne de pliage.We also know (FR-A-2-628-397) blanks in one piece from sheet material comprising on the one hand two sets of flaps articulated, which, by folding, are each susceptible to form part of the compartments of the cross, and on the other hand an intermediate panel, connected to two sets of shutters respectively along one line likely to be broken and along a line likely to serve as a fold line.

Ainsi, pour réaliser un croisillon à partir d'un tel flan, on sépare l'un des ensembles de volets du panneau intermédiaire, le long de la ligne susceptible d'être rompue, puis on procède à la mise en forme des ensembles de volets pour obtenir deux sous-ensembles de compartiments, le croisillon étant obtenu par accolement des sous-ensembles de compartiments contre le panneau intermédiaire, de part et d'autre de celui-ci.So, to make a crosspiece from a such blank, we separate one of the sets of flaps of the intermediate panel, along the line likely to be broken, then we proceed with the setting shaped sets of shutters to get two compartment sub-assemblies, the spider being obtained by joining subsets of compartments against the intermediate panel, on either side of it.

Ces flans d'une seule pièce, tels qu'ils viennent d'être décrits et bien qu'avantageux, présentent des inconvénients.These one-piece blanks, as they come to be described and although advantageous, present disadvantages.

En effet, ils n'autorisent pas une fabrication en automatique très rapide, notamment du fait de la séparation préalable du flan en deux avant formation du croisillon.Indeed, they do not authorize a manufacturing in very fast automatic, especially due to the prior separation of the blank into two before formation of the crosspiece.

La présente invention vise à fournir un procédé et une machine de formation de croisillons répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'elle va permettre une fabrication automatique rapide de croisillons avec une cadence pouvant atteindre trente croisillons à la minute, voire soixante croisillons dans un mode de réalisation avantageux permettant la formation de deux croisillons de façon simultanée, et ce pour un coût, une adaptabilité et une fiabilité de formation améliorés.The present invention aims to provide a method and a spider forming machine responding better than those previously known to the requirements of practice, in particular in that it will allow a rapid automatic production of cross bars with a rate of up to thirty crosses at the minute or even sixty crosses in a mode of advantageous realization allowing the formation of two braces simultaneously, for one cost, adaptability and reliability of training improved.

Dans ce but, l'invention propose notamment un procédé de fabrication automatique de croisillons en feuille de carton ondulé, pour le compartimentage de boítes, selon la revendication 1. To this end, the invention notably proposes a automatic manufacturing process of cross bars corrugated cardboard sheet, for the compartmentalisation of boxes according to claim 1.

En général, les deux demi-croisillons vont ainsi permettre la formation d'un seul croisillon de douze emplacements de bouteilles pour une même caisse.In general, the two half-crosses go thus allow the formation of a single cross of twelve bottle locations for the same case.

Par contre, dans le cas de la formation simultanée de deux croisillons, il s'agira alors de croisillons avec six emplacements de bouteilles chacun. However, in the case of simultaneous training two braces, they will then be braces with six bottle locations each.

Dans des modes de réalisation avantageux, on a de plus recours à l'une et/ou à l'autre des dispositions suivantes :

  • les piles de flans étant en biais l'une en face de l'autre, par rapport à un plan vertical, les premier et second flans sont saisis simultanément, puis chacun est amené au contact de l'autre par un mouvement de rotation de sens opposé à celui de l'autre ;
  • on forme les deux demis-croisillons ou les deux croisillons directement par poinçonnage, dans la ou les boítes correspondantes, en même temps que les moyens de préhension vont chercher les flans suivants.
In advantageous embodiments, use is made of one and / or the other of the following arrangements:
  • the stacks of blanks being diagonally opposite one another, with respect to a vertical plane, the first and second blanks are gripped simultaneously, then each is brought into contact with the other by a directional rotation movement opposite to that of the other;
  • the two half-braces or the two braces are formed directly by punching, in the corresponding box or boxes, at the same time as the gripping means will seek the following blanks.

       et le second ensemble comprenant un second volet de base rectangulaire muni sur un second côté d'extrémité d'un second volet d'extrémité pourvu de deux échancrures symétriques par rapport à l'axe de symétrie du croisillon, et sur les deux côtés adjacents audit second côté d'extrémité, de deux seconds volets latéraux, également symétriques par rapport audit axe, propres à s'insérer dans lesdites échancrures,
       les deux demi-croisillons ou croisillons sont formés en insérant lesdits premiers et seconds volets latéraux dans les échancrures correspondantes desdits premier et second volets d'extrémité en vis-à-vis ;
  • les seconds ensembles des seconds flans sont munis chacun d'un panneau central relié audit second ensemble correspondant par une ligne de pliage, la saisie du second flan s'effectuant par préhension par aspiration du panneau central, celui-ci étant positionné à la verticale symétriquement entre les deux ensembles de volets en contact ou sensiblement en contact l'un avec l'autre ;
  • le panneau central est mis en position verticale uniquement par rotation des moyens de préhension par aspiration dudit panneau central ;
  • on déplace les moyens de préhension par aspiration, par le biais d'un jeu de came et de poulies.
No lateral movement of the blanks is thus necessary, which allows high rates;

  • the second sets of the second blanks are each provided with a central panel connected to said second corresponding assembly by a fold line, the gripping of the second blank being effected by gripping by suction of the central panel, the latter being positioned vertically symmetrically between the two sets of flaps in contact or substantially in contact with each other;
  • the central panel is brought into vertical position only by rotation of the gripping means by suction of said central panel;
  • the gripping means are moved by suction, by means of a set of cams and pulleys.

L'invention propose également une machine de fabrication automatique de croisillons en feuille de carton ondulé, pour le compartimentage de boítes, selon la revendication 8. The invention also provides a machine for automatic production of sheet cross bars corrugated cardboard, for compartmentalizing boxes, according to claim 8.

Avantageusement, les moyens de stockage sont agencés pour présenter les piles de flans en biais l'une en face de l'autre, par rapport à un plan vertical, et les moyens de déplacement simultané sont agencés pour amener les flans respectivement au contact l'un de l'autre par rotation en sens opposé des moyens de préhension correspondante.Advantageously, the storage means are arranged to present the stacks of blanks at an angle one opposite the other, in relation to a plane vertical, and the means of simultaneous movement are arranged to bring the blanks respectively to the contact with each other by rotation in opposite direction corresponding gripping means.

Dans la suite les mêmes numéros de référence seront utilisés pour désigner les mêmes éléments. Dans le cas d'éléments similaires, de même dimension, mais en général symétriques par rapport à un axe, on utilisera les mêmes numéros avec indice.In the following the same reference numbers will be used to designate the same elements. In the case of similar elements, of the same dimension, but generally symmetrical with respect to an axis, we will use the same indexed numbers.

Les figures 1 et 2 montrent respectivement un premier flan 1 et un second flan 2 en matière de feuille de carton ondulé double face, par exemple de 3 mm d'épaisseur. Figures 1 and 2 respectively show a first blank 1 and a second blank 2 in terms of double-sided corrugated cardboard sheet, for example from 3 mm thick.

L'ensemble de flans 1 et 2 est destiné à former un croisillon de compartimentage pour une boíte, par exemple une caisse de bouteilles de vin, parallélépipédique, dont l'intérieur va ainsi pouvoir être divisé en douze compartiments de rétention de bouteille, de façon connue en elle-même.The set of blanks 1 and 2 is intended to form a compartmentalizing spider for a box, by example a case of wine bottles, parallelepiped, whose interior will thus be able be divided into twelve retention compartments of bottle, in a manner known per se.

Chacun des flans 1 et 2 est symétrique par rapport à un axe longitudinal 3.Each of the blanks 1 and 2 is symmetrical with respect to to a longitudinal axis 3.

Plus précisément les flans 1 et 2 comprennent respectivement un premier ensemble 4 et un second ensemble 4' de volets.More precisely the blanks 1 and 2 include respectively a first set 4 and a second 4 'set of shutters.

Chaque ensemble de volets comporte un premier ou second volet de base 5, 5', rectangulaire ou carré, muni respectivement sur un premier ou second côté d'extrémité 6, 6', d'un premier ou second volet d'extrémité 7, 7', et sur les deux côtés adjacents 8, 9 ; 8' 9' aux côtés d'extrémité de premier ou second volets latéraux 10, 11 ; 10', 11' respectivement symétriques par rapport à l'axe 3, les côtés 6, 6' et respectivement 8, 8 et 9, 9' formant des lignes de pliage perpendiculaires entre elles deux à deux.Each set of flaps has a first or second base panel 5, 5 ', rectangular or square, fitted respectively on a first or second side end 6, 6 ', of a first or second flap end 7, 7 ′, and on the two adjacent sides 8, 9; 8 '9' to the first or second end sides side flaps 10, 11; 10 ', 11' respectively symmetrical about axis 3, sides 6, 6 'and respectively 8, 8 and 9, 9 'forming lines of perpendicular folding between them two by two.

Les volets de base 5 ,5' comprenant un quatrième côté 12, 12', qui est libre pour le volet 5, par exemple muni d'une échancrure centrale en V 13, et qui est muni d'un panneau central 14 pour le côté 12' qui forme une ligne de pliage.The basic flaps 5, 5 'including a fourth side 12, 12 ', which is free for shutter 5, by example with a central V 13 notch, and which has a central panel 14 for the 12 'side which forms a fold line.

Le panneau 14 présente une forme au moins approximativement rectangulaire, de longueur l (perpendiculaire à l'axe 3) par exemple égale au triple de la dimension d des côtés 5, 5'.The panel 14 has an at least approximately rectangular shape, of length l (perpendicular to the axis 3), for example equal to three times the dimension d of the sides 5, 5 '.

Chaque volet d'extrémité 7, 7' est symétrique par rapport à l'axe 3 et présente une dimension perpendiculaire à l'axe 3 égale à la longueur l du panneau 14.Each end flap 7, 7 ′ is symmetrical with respect to the axis 3 and has a dimension perpendicular to the axis 3 equal to the length l of the panel 14.

Du côté opposé aux côtés d'extrémité 6, 6', chaque volet d'extrémité 7, 7' comporte deux échancrures 15, 15', parallèles à l'axe 3, qui partage le volet en trois bandes 16, 16' de largeurs sensiblement égales.On the side opposite to the end sides 6, 6 ', each end flap 7, 7 ′ has two notches 15, 15 ', parallel to axis 3, which shares the flap in three strips 16, 16 'of substantially equal widths.

Ces bandes sont solidaires les unes des autres par le reste du volet, du côté du volet de base 5, 5', et sont chacune de longueur d, les côtés 6, 6' se trouvant à la base de la bande 16, 16' médiane des volets d'extrémité 7, 7'.These bands are secured to each other by the rest of the flap, on the side of the base flap 5, 5 ', and are each of length d , the sides 6, 6' lying at the base of the strip 16, 16 ' median of the end flaps 7, 7 '.

Avantageusement, les fentes 15, 15' sont prolongées par des fentes f formées par une petite ligne de découpe, qui va permettre un meilleur encastrement ultérieur entre volets.Advantageously, the slots 15, 15 ′ are extended by slots f formed by a small cutting line, which will allow better subsequent embedding between flaps.

Les volets latéraux 10, 11 et 10' 11' présentent chacun une forme au moins approximativement en équerre, avec une première branche 17, 18 ;17', 18' perpendiculaire à l'axe 3 reliées respectivement au volet de base correspondant par les lignes de pliage formées par les côtés 8, 9 ; 8', 9' dudit volet de base, et une deuxième branche 19, 20 ; 19', 20', parallèle à l'axe 3 et disposée latéralement par rapport aux volets d'extrémité correspondant 7, 7'. The side flaps 10, 11 and 10 '11' have each one forms at least approximately in square, with a first branch 17, 18; 17 ', 18' perpendicular to axis 3 connected respectively to corresponding base flap by fold lines formed by the sides 8, 9; 8 ', 9' of said flap base, and a second branch 19, 20; 19 ', 20', parallel to axis 3 and arranged laterally by relative to the corresponding end flaps 7, 7 '.

Un espace de découpe 21, 21' sépare les volets d'extrémité des volets latéraux, une partie 22, 22' du volet latéral correspondant formant par exemple une languette d'excroissance qui pénètre dans les parties inférieures 23, 23', des bandes latérales des volets d'extrémité correspondant 16, 16'.A cutting space 21, 21 'separates the flaps end of side flaps, part 22, 22 ' of the corresponding side flap forming for example a tongue of protrusion which penetrates into the lower parts 23, 23 ', lateral bands of the corresponding end flaps 16, 16 '.

Avantageusement la hauteur H des branches 19, 20 ; 19', 20' est approximativement le double de la longueur c des côtés 8, 9 ; 8', 9', qui peut par exemple elle-même être égale à d.Advantageously, the height H of the branches 19, 20; 19 ', 20' is approximately twice the length c of the sides 8, 9; 8 ', 9', which can for example itself be equal to d .

Dans le mode de réalisation plus particulièrement décrit ici, les volets et le panneau central sont munis sur leurs bords libres dirigés vers l'extérieur du flan, d'échancrures triangulaires 24, qui permettent un meilleur contact des arêtes du croisillon une fois formé avec les parois de la caisse.In the embodiment more particularly described here, the shutters and the central panel are provided on their free edges directed outwards of the blank, of triangular notches 24, which allow better contact of the edges of the once formed with the walls of the checkout.

La figure 3 montre schématiquement les moyens 25 de formation d'un croisillon par dépilage, jonction et poinçonnage des flans, selon le mode de réalisation de l'invention plus particulièrement décrit ici.FIG. 3 schematically shows the means 25 for forming a spider by unstacking, junction and punching the blanks, depending on the mode of embodiment of the invention more particularly described here.

La machine comporte deux magasins 26, 27 de stockage de flans en vis-à-vis, à savoir un premier magasin 26 de stockage de premiers flans 1 en position sensiblement verticale, en biais, penché par exemple avec un angle de 30°, vers les moyens 25 et un second magasin 27, de stockage de seconds flans 2 également en position sensiblement verticale par exemple en biais penché vers les moyens 25 avec un angle de l'ordre de 10°.The machine has two magazines 26, 27 of storage of blanks facing each other, namely a first store 26 for storing first blanks 1 in substantially vertical position, at an angle, tilted by example with an angle of 30 °, towards means 25 and a second store 27, for storing second blanks 2 also in a substantially vertical position by example at an angle leaning towards means 25 with a angle of the order of 10 °.

Les piles de flans sont alimentées latéralement de façon connue en elles-mêmes par des moyens pousseurs (non représentés).The blank stacks are fed laterally from way known in themselves by pushing means (not shown).

La machine comporte par ailleurs des moyens 29, 30 de préhension par aspiration, d'un côté (moyens 29) du volet de base 5 du premier flan 1, et de l'autre côté (moyens 30) du panneau central 14 du second flan 2.The machine also includes means 29, 30 gripping by suction, on one side (means 29) of the base flap 5 of the first blank 1, and of the other side (means 30) of the central panel 14 of the second blank 2.

Chaque moyen 29, 30 comprend un équipage mobile 31, 32 actionné par une même came rotative 33, elle-même actionnée en rotation par un moteur 34.Each means 29, 30 comprises a mobile assembly 31, 32 actuated by the same rotary cam 33, itself actuated in rotation by a motor 34.

Le premier équipage 31 comporte une première pièce de support 35 de ventouses 36 reliée à une première bielle 37 de commande et le second équipage 32 comporte quant à lui, une seconde pièce de support 38 de ventouses 39 reliées à une seconde bielle 40 de commande, lesdites bielles étant reliées de façon articulée à la came 33.The first crew 31 comprises a first part support 35 of suction cups 36 connected to a first control rod 37 and the second crew 32 includes a second support piece 38 suction cups 39 connected to a second connecting rod 40 of control, said connecting rods being connected so articulated to cam 33.

Les moyens 25 comportent de plus des moyens 41 de poinçonnage du flan une fois mis en équerre, comprenant une colonne 42 de poinçonnage muni de moyens 43 de butée sur l'ensemble de flans et une bielle 44 d'actionnement de la colonne 42 montée en rotation sur une tige 45 solidaire en rotation de la came 33 d'actionnement des moyens de préhension.The means 25 also comprise means 41 for punching the blank once set square, comprising a punching column 42 provided with abutment means 43 on the blank assembly and a connecting rod 44 for actuating the column 42 mounted in rotation on a rod 45 integral in rotation with the cam 33 for actuating the gripping means.

On va maintenant décrire le procédé de réalisation du croisillon selon le mode de réalisation de l'invention plus particulièrement décrit, en référence aux figures 3A à 3L.We will now describe the production process of the crosspiece according to the embodiment of the invention more particularly described, in reference to Figures 3A to 3L.

La position de départ (figure 3A) montre les ventouses 36, 39 des moyens de préhension 29, 30 en position sur les parties 5 et 14 de leurs flans respectifs 1 et 2.The starting position (Figure 3A) shows the suction cups 36, 39 gripping means 29, 30 in position on parts 5 and 14 of their blanks respectively 1 and 2.

Les ventouses sont alors mises sur vide par un circuit de mise au vide embarqué (non représenté). En appréhendant les flans par aspiration, elles permettent le décollement des flans 1 et 2 de leur pile de flans respectivement placée dans les magasins 26 et 27, puis leur déplacement comme représenté sur les figures 3B à 3F.The suction cups are then put on vacuum by a on-board vacuum circuit (not shown). In apprehending the blanks by suction, they allow the detachment of the blanks 1 and 2 of their stack of blanks respectively placed in the stores 26 and 27, then their displacement as shown on Figures 3B to 3F.

Pour ce faire, les pièces de support allongées 35 et 38 sont montées mobiles en rotation autour des axes 46, 47 placés à l'une de leurs extrémités et parallèles entre eux. Elles sont actionnées en rotation par leurs bielles respectives 31 et 32.To do this, the elongated support pieces 35 and 38 are mounted mobile in rotation around the axes 46, 47 placed at one of their ends and parallel to each other. They are operated in rotation by their respective connecting rods 31 and 32.

Chaque bielle est solidaire, d'un côté des pièces (par exemple au milieu de la longueur du support correspondant), et de l'autre côté du système à came (ou came) 33 actionnée par le moteur rotatif 34.Each connecting rod is integral, on one side of the parts (for example in the middle of the support length corresponding), and on the other side of the cam system (or cam) 33 actuated by the rotary motor 34.

La rotation de la came 33, en ramenant les bielles vers le bas, fait pivoter les pièces 35 et 38 en rotation, et par le biais de guidage latéraux adéquats (non représentés) d'une part fait pivoter le panneau 14 du flan jusqu'à une position verticale (Cf. figures 3E et 3F), et d'autre part fait pivoter les ensembles de volets des flans 1 et 2 jusqu'à les amener en position horizontale (figure 3F) de sorte qu'ils entrent en contact l'un avec l'autre dans le plan horizontal au niveau des côtés 12 et 12' des volets de bases 5 et 5'.The rotation of the cam 33, by bringing back the connecting rods down, rotate parts 35 and 38 in rotation, and through lateral guides on the one hand rotates the blank panel 14 to a vertical position (Cf. figures 3E and 3F), and on the other hand rotates the shutter sets of blanks 1 and 2 up to the bring it to a horizontal position (figure 3F) so that they come into contact with each other in the horizontal plane at the sides 12 and 12 'of the base flaps 5 and 5 '.

Comme on peut également le constater sur les figures 3A à 3F, et simultanément à l'actionnement des pièces de support, la colonne 42 de pistonnage se déplace entre une position basse au moment de la préhension des flans (figure 3A) et une position haute (figure 3F et 3G), pour laquelle les deux flans sont en contact l'un contre l'autre, le panneau 14 étant vertical entre les deux.As can also be seen on the Figures 3A to 3F, and simultaneously with actuation support parts, the piston 42 column is moves between a low position at the time of gripping the blanks (Figure 3A) and a position high (Figure 3F and 3G), for which the two blanks are in contact with each other, the panel 14 being vertical in between.

Pour ce faire, la tige 45, solidaire d'un côté de la came 33 et de l'autre côté d'une oreille 48 fixée en partie supérieure à la colonne de poinçonnage 42, pivote entre une première position (Cf. figure 3) et une deuxième position (Cf. figure 3F) formant un angle au centre compris entre 140° et 200°, par exemple 160°, permettant de déplacer la colonne 42 entre sa position basse de poinçonnage et sa position haute.To do this, the rod 45, integral with one side of the cam 33 and on the other side of an ear 48 fixed in the upper part of the punching column 42, swivels between a first position (see figure 3) and a second position (see FIG. 3F) forming a angle at the center between 140 ° and 200 °, by example 160 °, allowing column 42 to be moved between its low punching position and its position high.

Plus précisément, et en faisant référence aux figures suivantes 3G à 3L, la colonne 42 descend au fur et à mesure de la remontée des pièces de support 35 et 38 qui viennent chercher de nouveaux flans, ce qui permet de pistonner (Cf. figures 3J ou 3L) les flans ainsi jonctionnés vers le bas et de les conformer dans la forme définitive du croisillon en même temps que ce dernier est introduit dans la boíte qu'il va équiper (non représentée).Specifically, and with reference to following figures 3G to 3L, column 42 goes down to as the support pieces rise 35 and 38 who come to look for new blanks, this which allows to boost (Cf. figures 3J or 3L) the blanks thus junctioned down and from them conform in the final form of the cross in at the same time as the latter is introduced into the box that it will equip (not shown).

La figure 4 montre une vue en perspective de la machine 50 selon l'invention.Figure 4 shows a perspective view of the machine 50 according to the invention.

Celle-ci comprend un bâti 51 de support par exemple sensiblement parallélépipédique, et donc très compact, un tapis roulant inférieur 52 d'amenée des boítes préformées en dessous des moyens 25 de formation du croisillon, des magasins 26 et 27 de stockage des flans 1 et 2.This includes a support frame 51 by substantially parallelepipedic example, and therefore very compact, a lower conveyor belt 52 for feeding preformed boxes below the means 25 of formation of the spider, stores 26 and 27 of storage of blanks 1 and 2.

Les moyens de stockage comprennent des éléments de support des flans en position sensiblement verticale, penchée, constitués de façon connue elle-même.The storage means include elements of blank support in a substantially vertical position, leaning, constituted in a known manner itself.

Les moyens 25 de formation du croisillon vont maintenant être encore détaillés en référence aux figures 5 à 10.The means 25 for forming the spider will now be further detailed with reference to Figures 5 to 10.

La figure 5 est une vue en perspective d'un mode de réalisation des moyens 25 de formation du croisillon selon l'invention.Figure 5 is a perspective view of a mode of means 25 for training the spider according to the invention.

Les moyens 25 comprennent les moyens 29, 30 de préhension par aspiration des flans.The means 25 include the means 29, 30 of gripping by suction of the blanks.

Par la suite on décrira les moyens 30 de préhension du flan 2, étant entendu que les moyens 29, de préhension du flan 1 sont sensiblement identiques, sauf en ce qui concerne le système à poulie qui diffère en partie comme cela sera précisé ci-après.Thereafter we will describe the means 30 of gripping the blank 2, it being understood that the means 29, gripping the blank 1 are substantially identical except for the system at pulley which differs in part as will be specified below.

Egalement et en référence à la figure 6, les moyens 30 comportent un équipage mobile comprenant une pièce de support 38 formée par une barre centrale 53 solidaire des deux ventouses 39 fixées vers le centre de la barre.Also and with reference to FIG. 6, the means 30 comprise a mobile assembly comprising a support piece 38 formed by a central bar 53 integral with the two suction cups 39 fixed towards the center of the bar.

La barre 53 est mobile en rotation autour des extrémités de deux cornières latérales 54, dont les autres extrémités sont solidaires d'une barre 55 de support fixée au bâti 51.The bar 53 is movable in rotation around the ends of two lateral angles 54, the other ends are integral with a bar 55 of support fixed to the frame 51.

L'une des cornières latérales est fixée en rotation par l'intermédiaire d'une platine latérale 56 à une extrémité de la bielle 40 dont l'autre extrémité est raccordée au dispositif 57 solidaire en rotation de la came 33.One of the side angles is fixed in rotation via a side plate 56 at one end of the connecting rod 40 of which the other end is connected to the device 57 integral with rotation of the cam 33.

Des moyens 58 d'alimentation en vide des ventouses 39 par un tube d'aspiration 59 sont prévus et fixés au bâti.Means 58 for supplying vacuum to the suction cups 39 by a suction tube 59 are provided and fixed to the frame.

Plus précisément les moyens 57 selon le mode de réalisation décrit ici comprennent un moteur 34 d'actionnement de la came 33, par le biais d'une courroie 60.More precisely, the means 57 according to the mode of realization described here include a motor 34 actuation of the cam 33, by means of a belt 60.

La came 33 est solidaire en rotation via un arbre de fonction 61, avec un disque 62, lui-même directement solidaire d'une extrémité montée sur rotule, de la bielle 37 d'actionnement de la pièce support 35 du premier flan 1, et via une courroie 63 et un deuxième disque 64, d'une extrémité montée ici encore sur rotule, de la bielle 40 d'actionnement de la pièce de support 38 du second flan 2.The cam 33 is integral in rotation via a shaft function 61, with a disc 62, itself directly attached to one end mounted on ball joint, connecting rod 37 for actuating the part support 35 of the first blank 1, and via a belt 63 and a second disc 64, from one end mounted here still on ball joint, connecting rod 40 for actuating the support piece 38 of the second blank 2.

La came 33 est également solidaire en rotation de la tige 45 dont l'autre extrémité est solidaire, par le biais d'un palier 65, d'une bielle 44 d'actionnement de la colonne 42 de poinçonnage qui est également précisée en référence à la figure 9.The cam 33 is also integral in rotation with the rod 45, the other end of which is integral, by through a bearing 65, a connecting rod 44 actuation of the punching column 42 which is also specified with reference to FIG. 9.

L'autre extrémité de la bielle 44 est raccordée, via une rotule 66 à une plaque 67 solidaire d'un axe 68 lui-même fixé à un bras 69 dont l'extrémité 70 est raccordée par le biais d'une rotule 71, à une biellette 72 de poinçonnage.The other end of the connecting rod 44 is connected, via a ball joint 66 to a plate 67 secured to an axis 68 itself fixed to an arm 69 whose end 70 is connected by means of a ball joint 71, to a punching link 72.

La biellette 72 est agencée pour actionner la colonne 42 verticalement entre deux positions, une position haute de mise en place des flans en contact par la tranche, et une position basse de poinçonnage pour formation du croisillon dans la boíte.The link 72 is arranged to actuate the column 42 vertically between two positions, one high position for placing the blanks in contact by the edge, and a low punching position for formation of the cross in the box.

Avantageusement la colonne 42 est formée de deux tubes 73, terminée au niveau de leur extrémité de butée 43 par des ventouses à soufflets 74 alimentés en vide par le haut, grâce au système de vide 58.Advantageously, the column 42 is formed of two tubes 73, terminated at their end of stop 43 by bellows suction cups 74 supplied in vacuum from above, thanks to the vacuum system 58.

La colonne 42 est par ailleurs soutenue horizontalement par une traverse 75 à laquelle elle est fixée à une de ses extrémités, l'autre extrémité de la traverse 75 étant fixée à une pièce 76 formée par un plateau agencé pour glisser verticalement entre deux rails de guidage verticaux 77.Column 42 is also supported horizontally by a cross member 75 to which it is attached to one end, the other end of the crosspiece 75 being fixed to a piece 76 formed by a tray arranged to slide vertically between two vertical guide rails 77.

On va maintenant décrire plus précisément en référence aux figures 7A 7B, 8A et 8B les supports de ventouses pour les premier et second flans.We will now describe more precisely in reference to FIGS. 7A 7B, 8A and 8B the supports for suction cups for the first and second blanks.

Les figures 7A et 7B montrent, en vue latérale, la position haute de préhension du premier flan par les ventouses 36 à soufflets (figure 7A), et la position basse, à l'horizontale, pour la pose à plat du flan (figure 7B).FIGS. 7A and 7B show, in side view, the high position for gripping the first blank by the bellows suction cups 36 (FIG. 7A), and the position low, horizontal, for laying flat blanks (Figure 7B).

Pour passer de la position de préhension des flans stockés (figure 7A) à la position à plat (figure 7B), les ventouses doivent tourner de 180° par rapport à la branche support 78 des ventouses. Pour ce faire, une poulie 79, fixe par rapport au bâti, actionne par la biais d'une courroie 80, une poulie 81 solidaire des ventouses.To move from the blank gripping position stored (Figure 7A) in the flat position (Figure 7B), the suction cups must rotate 180 ° with respect to the support branch 78 of the suction cups. To do this, a pulley 79, fixed relative to the frame, actuates by through a belt 80, a pulley 81 secured suction cups.

Lors de la rotation de la branche support, dans le sens de la flèche 82, les ventouses tournent autour de l'axe 83 d'extrémité de ladite branche pour prendre la bonne position.During the rotation of the support branch, in the direction of arrow 82, the suction cups rotate around of the axis 83 of the end of said branch for take the right position.

Les figures 8A et 8B montrent le système de ventouses 39 associé au second flan.Figures 8A and 8B show the suction cups 39 associated with the second blank.

La figure 8A montre la position haute dans laquelle les ventouses 39 sont parallèles au magasin.Figure 8A shows the high position in which the suction cups 39 are parallel to the store.

La figure 8B montre la position basse avec pose verticale du panneau 14.Figure 8B shows the low position with installation vertical of the panel 14.

Pour ce faire, il est prévu à une extrémité de la branche support 54 une grande poulie 84 qui peut être rendue fixe par rapport au bâti.To do this, it is provided at one end of the support branch 54 a large pulley 84 which can be made fixed relative to the frame.

Dans le cas où le montage prévu est celui de deux croisillons formés simultanément, il est également prévu une petite poulie 85 qui peut elle aussi être rendue fixe en rotation par rapport au bâti (la grande poulie est alors par contre rendue libre).In the case where the planned assembly is that of two braces formed simultaneously it is also provided a small pulley 85 which can also be made fixed in rotation relative to the frame (the large pulley is then made free).

Un double jeu de courroies 86, 87 respectivement reliées aux poulies 84 et 85, permet d'actionner une poulie d'extrémité 88 permettant de placer les ventouses 39 avec lesquelles elle est solidaire en rotation, dans la bonne position lors de la rotation (flèche 89), c'est-à-dire soit verticale avec la grande poulie fixée par rapport au bâti (comme représenté sur la figure) ou horizontale avec la petite poulie fixée par rapport au bâti (non représenté), de façon similaire à la figure 7B.A double set of belts 86, 87 respectively connected to pulleys 84 and 85, used to activate a end pulley 88 for placing the suction cups 39 with which it is integral in rotation, in the correct position when rotating (arrow 89), i.e. either vertical with the large pulley fixed relative to the frame (as shown in the figure) or horizontal with the small pulley fixed relative to the frame (not shown), similar to Figure 7B.

On a représenté sur la figure 10, ce façon schématique, la formation définitive du croisillon par poinçonnage dans la caisse.We have shown in Figure 10, this way schematic, the final formation of the cross by punching in the box.

Les extrémités 43 de la colonne 42 de poinçonnage, munies de ventouses aspirantes, maintiennent les flans 1 et 2 en position d'équerre.The ends 43 of the punching column 42, fitted with suction cups, hold the blanks 1 and 2 in square position.

La colonne descend selon la flèche 90.The column descends according to arrow 90.

Des formes 91 de guidage par exemple quatre ou huit, en forme de plaque recourbée vers l'extérieur en partie supérieure, propres à refermer les parois du croisillon sur lui-même, sont prévues. Elles permettent au croisillon de se former définitivement avant de rentrer dans la caisse 92 qui peut ensuite être évacuée par le tapis roulant 52 (flèche 93).Guiding forms 91 for example four or eight, plate-shaped curved outward in the upper part, suitable for closing the walls of the crosspiece on itself, are provided. They allow the spider to form definitively before entering box 92 which can then be evacuated by the conveyor belt 52 (arrow 93).

Enfin, on a représenté sur les figures 11A à 11C, sous la machine mise en oeuvre pour raison de clarté, l'ensemble de flans 1 et 2 après présentation à l'équerre (figure 11A), puis pliage par rabattement des côtés et encastrement dans les encoches 15 des parois 10, 11, 10', 11' (figure 11B). Finally, FIGS. 11A to 11C show, under the machine used for clarity, the set of blanks 1 and 2 after presentation to the square (figure 11A), then folding by folding from the sides and fitting into the notches 15 of walls 10, 11, 10 ', 11' (Figure 11B).

On obtient alors le croisillon 95 tel que représenté sur la figure 11C qui va s'insérer dans le volume interne de la caisse à garnir représenté en trait mixte 96 sur la figure.We then obtain the crosspiece 95 such that shown in Figure 11C which will fit into the internal volume of the box to be filled represented in mixed line 96 in the figure.

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 deux croisillons de six emplacements sont formés simultanément et poinçonnés dans deux caisses en contrebas par le même mouvement.As it goes without saying and as it also results of the above, the present invention is not limited to more embodiments particularly described. She embraces contrary all the variants and in particular those where two braces of six locations are formed simultaneously and punched in two boxes in below by the same movement.
