Description

La présente invention concerne un dispositif de rangement en pile d'éléments en forme de feuilles dans une machine de façonnage. L'invention concerne également une machine de façonnage d'éléments en forme de feuilles comportant au moins un tel dispositif de rangement.The present invention relates to a device for stacking elements in the form of sheets in a shaping machine. The invention also relates to a machine for shaping sheet-like elements comprising at least one such storage device.

Dans l'industrie de fabrication des emballages, les feuilles sont par exemple découpées selon une matrice correspondant à la forme développée que l'on souhaite obtenir, par exemple en vue d'obtenir une pluralité de boîtes d'une forme donnée. Après découpe et éjection des déchets, les points d'attache entre les feuilles de poses sont rompus et les feuilles de poses s'empilent dans une zone de réception où elles sont rangées en piles verticales par un rangeur.In the packaging manufacturing industry, the sheets are for example cut according to a die corresponding to the developed shape that one wishes to obtain, for example with a view to obtaining a plurality of boxes of a given shape. After cutting and ejecting the waste, the points of attachment between the sheets of poses are broken and the sheets of poses pile up in a reception zone where they are arranged in vertical piles by a ranger.

A chaque arrivée d'une nouvelle feuille, une grille de rangement actionnée par des bras articulés pivote légèrement d'une position inclinée dans une position verticale, pour accueillir et ranger la feuille en pile. La grille de rangement reprend ensuite sa position inclinée « en entonnoir » pour la réception d'une nouvelle feuille. Ce mouvement alternatif de va-et-vient de la grille de rangement est également appelé « mouvement de taquage ».Each time a new sheet arrives, a storage grid actuated by articulated arms pivots slightly from an inclined position to a vertical position, to receive and store the sheet in a stack. The storage grid then resumes its inclined "funnel" position to receive a new sheet. This alternating back and forth movement of the storage grid is also called "jogging movement".

Afin de contrôler la qualité de façonnage des feuilles, il s'avère nécessaire de prélever régulièrement des échantillons en cours de production.In order to control the quality of shaping of the sheets, it is necessary to take samples regularly during production.

Pour cela, certains systèmes prévoient de dégager un accès à la pile à l'endroit du rangeur, en repliant les bras qui pivotent la grille de rangement vers l'arrière et vers le bas. Lorsque les bras sont repliés, la grille de rangement a également pivoté à l'horizontale mais reste toujours devant la pile, dans le chemin d'accès à la pile. L'accès à la pile ainsi dégagé au-dessus de la grille est étroit, ce qui ne facilite pas le travail de l'opérateur souhaitant prendre un échantillon. US 5,544,583 qui décrit le préambule de la revendication 1, ou US 5,749,571 donnent d'autres exemples.For this, some systems plan to provide access to the stack at the location of the storage unit, by folding the arms which pivot the storage grid backwards and downwards. When the arms are folded, the storage rack has also rotated horizontally but still remains in front of the stack, in the path to the stack. Access to the pile thus released above the grid is narrow, which does not facilitate the work of the operator wishing to take a sample.

Un des buts de la présente invention est donc de proposer un dispositif de rangement de feuilles en piles permettant un prélèvement plus aisé des feuilles.One of the aims of the present invention is therefore to propose a device for storing sheets in stacks allowing easier removal of the sheets.

A cet effet, la présente invention a pour objet un dispositif de rangement pour le rangement en pile d'éléments en forme de feuilles dans une machine de façonnage, le dispositif de rangement comportant :

  • une surface de rangement mobile, et
  • un dispositif d'actionnement pour déplacer la surface de rangement :
    • entre une position de retrait et une position avant verticale dans un mouvement alternatif de va-et-vient pour le rangement des feuilles, et
    • entre la position de retrait et une position escamotée pour libérer l'accès à la pile d'éléments en forme de feuilles,
caractérisé en ce que le dispositif d'actionnement comporte des moyens de came configurés pour déplacer la surface de rangement vers le haut en position escamotée, dans une position haute destinée à être située au-dessus du sommet de la pile de feuilles.To this end, the subject of the present invention is a storage device for the storage in a stack of elements in the form of sheets in a shaping machine, the storage device comprising:
  • a mobile storage surface, and
  • an actuating device for moving the storage surface:
    • between a retracted position and a vertical forward position in an alternating back and forth motion for storing the sheets, and
    • between the retracted position and a retracted position to free access to the stack of sheet-like elements,
characterized in that the actuating device comprises cam means configured to move the storage surface upwards in the retracted position, in a high position intended to be located above the top of the stack of sheets.

L'accès à la pile de feuilles est ainsi libéré sur toute sa hauteur.Access to the stack of sheets is thus released over its entire height.

Pour cela, les moyens de came comportent au moins un premier galet suiveur fixé à la surface de rangement et au moins un premier profil de commande coopérant avec le au moins un premier galet suiveur pour guider ledit déplacement de la surface de rangement.For this, the cam means comprise at least one first follower roller fixed to the storage surface and at least one first control profile cooperating with the at least one first follower roller to guide said movement of the storage surface.

Selon un exemple de réalisation, les moyens de came, comprenant le au moins un premier galet suiveur et le au moins un premier profil de commande configurés pour déplacer la surface de rangement entre la position de retrait et la position escamotée vers le haut, sont les mêmes que ceux configurés pour déplacer la surface de rangement entre ladite position de retrait et la position avant verticale dans le mouvement alternatif de va-et-vient pour le rangement des feuilles.According to an exemplary embodiment, the cam means, comprising the at least one first follower roller and the at least one first control profile configured to move the storage surface between the retracted position and the retracted position upwards, are the same as those configured to move the storage surface between said retracted position and the vertical forward position in the back-and-forth reciprocating motion for sheet storage.

Le guidage des déplacements de la surface de rangement par le au moins un premier galet suiveur et le au moins un premier profil de commande, au lieu d'un axe de pivotement articulé, permet d'escamoter la surface de rangement au-dessus de la pile de feuilles. Il est ainsi possible de prévoir de façon simple, robuste et économique, des mouvements adaptés de la surface de rangement en optimisant le design fonctionnel du au moins un premier profil de commande, pour dégager un large accès à la pile dans la zone de réception pour le prélèvement aisé d'éléments en forme de feuilles.The guiding of the movements of the storage surface by the at least one first follower roller and the at least one first control profile, instead of an articulated pivot axis, makes it possible to retract the storage surface above the stack of sheets. It is thus possible to provide, in a simple, robust and economical way, suitable movements of the storage surface by optimizing the functional design of at least a first control profile, to provide wide access to the battery in the reception area for the easy removal of leaf-shaped elements.

Selon un exemple de réalisation, le au moins un premier profil de commande est droit.According to an exemplary embodiment, the at least one first control profile is straight.

La droite du au moins un premier profil de commande forme par exemple un angle inférieur à 30° avec l'horizontale.The straight line of the at least one first control profile forms, for example, an angle of less than 30° with the horizontal.

Les moyens de came comportent au moins un deuxième galet suiveur fixé à la surface de rangement au-dessous du au moins un premier galet suiveur et au moins un deuxième profil de commande coopérant avec le au moins un deuxième galet suiveur.The cam means comprise at least one second follower roller fixed to the storage surface below the at least one first follower roller and at least one second control profile cooperating with the at least one second follower roller.

Une première portion du au moins un deuxième profil de commande est courbe pour guider le déplacement de la surface de rangement entre la position de retrait et la position avant verticale et une deuxième portion du deuxième profil de commande est droite pour guider le déplacement de la surface de rangement entre la position de retrait et la position escamotée.A first portion of the at least one second control profile is curved to guide the movement of the storage surface between the retracted position and the vertical front position and a second portion of the second control profile is straight to guide the movement of the surface storage between the retracted position and the retracted position.

Selon un exemple de réalisation, les moyens de came, comprenant le au moins un deuxième galet suiveur et le au moins un deuxième profil de commande configurés pour déplacer la surface de rangement entre la position de retrait et la position escamotée vers le haut, sont les mêmes que ceux configurés pour déplacer la surface de rangement entre ladite position de retrait et la position avant verticale dans le mouvement alternatif de va-et-vient pour le rangement des feuilles.According to an exemplary embodiment, the cam means, comprising the at least one second follower roller and the at least one second control profile configured to moving the storage surface between the retracted position and the retracted upward position are the same as those configured to move the storage surface between said retracted position and the vertical forward position in the reciprocating back and forth motion for storing sheets.

La droite de la deuxième portion du au moins un deuxième profil de commande forme par exemple un angle inférieur à 30° avec la verticale.The straight line of the second portion of the at least one second control profile forms, for example, an angle of less than 30° with the vertical.

La deuxième portion du deuxième profil de commande croise par exemple la direction du premier profil de commande.The second portion of the second command profile crosses for example the direction of the first command profile.

Les galets suiveurs sont agencés sur la surface de rangement par exemple pour que leur coopération avec les profils de commande dans la position escamotée déplace la surface de rangement en position haute en formant un angle inférieur à 30° avec l'horizontale.The cam followers are arranged on the storage surface, for example so that their cooperation with the control profiles in the retracted position moves the storage surface into the high position by forming an angle of less than 30° with the horizontal.

Le au moins un premier profil de commande et le au moins un deuxième profil de commande peuvent être décalés latéralement pour empêcher le au moins un premier galet suiveur de coopérer avec le au moins un deuxième profil de commande, notamment lorsque le premier galet suiveur suivant le premier profil de commande revient de la position escamotée et croise le deuxième profil de commande.The at least one first control profile and the at least one second control profile can be offset laterally to prevent the at least one first follower roller from cooperating with the at least one second control profile, in particular when the first follower roller following the first control profile returns from the retracted position and crosses the second control profile.

Le au moins un premier ou deuxième profil de commande est par exemple formé dans une rainure.The at least one first or second control profile is for example formed in a groove.

Le dispositif d'actionnement peut comporter au moins un organe élastique ayant une extrémité fixe et une extrémité fixée à la surface de rangement pour assurer un contact du au moins un premier galet suiveur sur le au moins un premier profil de commande et, le cas échéant, du au moins un deuxième galet suiveur sur le au moins un deuxième profil de commande. L'organe élastique permet de s'assurer que les galets suiveurs appuient sur un profil de commande respectif.The actuating device may comprise at least one elastic member having a fixed end and an end fixed to the storage surface to ensure contact of the at least one first follower roller on the at least one first control profile and, if necessary , of the at least one second follower roller on the at least one second control profile. The elastic member makes it possible to ensure that the follower rollers bear on a respective control profile.

Selon un exemple de réalisation, les moyens de came comportent deux premiers galets suiveurs, chacun fixé à une extrémité respective de la surface de rangement et deux premiers profils de commande coopérant avec un premier galet suiveur respectif.According to an exemplary embodiment, the cam means comprise two first follower rollers, each fixed to a respective end of the storage surface and two first control profiles cooperating with a respective first follower roller.

Selon un exemple de réalisation, les moyens de came comportent deux deuxièmes galets suiveurs, chacun fixé à une extrémité respective de la surface de rangement au-dessous d'un premier galet suiveur et deux deuxièmes profils de commande coopérant avec un deuxième galet suiveur respectif.According to an exemplary embodiment, the cam means comprise two second follower rollers, each fixed to a respective end of the storage surface below a first follower roller and two second control profiles cooperating with a respective second follower roller.

Le dispositif d'actionnement comporte par exemple au moins un actionneur pour entraîner le déplacement de la surface de rangement.The actuating device comprises for example at least one actuator to drive the movement of the storage surface.

Le au moins un actionneur comporte par exemple un double vérin pneumatique configuré pour déplacer la surface de rangement entre la position de retrait et la position avant verticale sur une petite course et pour déplacer la surface de rangement entre la position de retrait et la position escamotée sur une grande course.The at least one actuator comprises for example a double pneumatic cylinder configured to move the storage surface between the retracted position and the vertical front position over a short stroke and to move the storage surface between the retracted position and the retracted position on a great race.

L'invention a aussi pour objet une machine de façonnage d'éléments en forme de feuilles, caractérisée en ce qu'elle comporte au moins un dispositif de rangement en pile d'éléments en forme de feuilles tel que décrit précédemment.The invention also relates to a machine for shaping sheet-shaped elements, characterized in that it comprises at least one storage device in a stack of sheet-shaped elements as described above.

De simples caractéristiques de différents modes de réalisation peuvent également être combinées ou interchangées pour fournir d'autres réalisations.In these figures, identical elements bear the same reference numbers.

Simple features of different embodiments can also be combined or interchanged to provide other embodiments.

On définit les termes amont et aval en référence à la direction longitudinale de déplacement des feuilles D (Figure 1). Les feuilles se déplacent d'amont en aval, en suivant généralement l'axe principal longitudinal de la machine, dans un mouvement cadencé par des arrêts périodiques.The terms upstream and downstream are defined with reference to the longitudinal direction of movement of the sheets D ( Figure 1 ). The sheets move from upstream to downstream, generally following the main longitudinal axis of the machine, in a rhythmic movement with periodic stops.

Les termes « éléments en forme de feuilles » et « feuilles » seront considérés comme équivalents, et concerneront aussi bien des éléments composés de carton ondulé que de carton plat, de papier ou de toute autre matière utilisée couramment dans l'industrie de l'emballage. Il est entendu que dans l'ensemble de ce texte, les termes « feuille » ou « élément en feuilles » ou « élément en forme de feuilles » désignent de façon très générale tout support d'impression en forme de feuilles tel que, par exemple, des feuilles de carton, de papier, de matière plastique, etc..The terms "sheet-shaped elements" and "sheets" will be considered equivalent, and will concern elements made of corrugated cardboard as well as flat cardboard, paper or any other material commonly used in the packaging industry. . It is understood that throughout this text, the terms "sheet" or "element in sheets" or "element in the form of sheets" refer very generally to any printing medium in the form of sheets such as, for example , sheets of cardboard, paper, plastic, etc.

Les termes « dessus », « dessous », « haut », « bas » « horizontale » et « verticale » sont définis en référence à la disposition des éléments dans une machine de façonnage posée au sol.The terms "above", "below", "top", "bottom", "horizontal" and "vertical" are defined with reference to the arrangement of the elements in a shaping machine placed on the ground.

La Figure 1 représente un exemple de machine de façonnage 1 pour la transformation de feuilles. Cette machine de façonnage 1 est classiquement composée de plusieurs stations de travail qui sont juxtaposées mais interdépendantes une à une pour former un ensemble unitaire. On trouve ainsi une station d'introduction 100, une table de marge 200, une station de transformation 300 par exemple pour la découpe, le gaufrage ou l'estampage des feuilles, telle que comprenant une presse à platines 301, une station d'éjection des déchets 400 dans le cas d'une machine de découpe ou une station d'alimentation de bandes 400 dans le cas d'une machine d'estampage, une station de réception des feuilles 500 où les feuilles transformées sont reconditionnées en pile.The Figure 1 represents an example of a shaping machine 1 for the transformation of sheets. This shaping machine 1 is conventionally composed of several work stations which are juxtaposed but interdependent one by one to form a unitary assembly. There is thus an introduction station 100, a feed table 200, a transformation station 300 for example for cutting, embossing or stamping the sheets, such as comprising a platen press 301, a scrap ejection station 400 in the case of a cutting machine or a strip supply station 400 in the case of a stamping machine, a 500 sheets where the processed sheets are repackaged in a pile.

L'opération de transformation de chaque feuille s'opère dans la station de transformation 300, par exemple entre une platine fixe et une platine mobile inférieure de la presse 301 pour la découpe des feuilles selon une matrice correspondant à la forme développée que l'on souhaite obtenir, par exemple en vue d'obtenir une pluralité de boîtes d'une forme donnée. La platine mobile s'élève et s'abaisse successivement une fois au cours de chaque cycle machine.The transformation operation of each sheet takes place in the transformation station 300, for example between a fixed platen and a lower movable platen of the press 301 for cutting the sheets according to a die corresponding to the developed shape that is wishes to obtain, for example with a view to obtaining a plurality of boxes of a given shape. The movable platen successively raises and lowers once during each machine cycle.

Un dispositif de transport 70 est par ailleurs prévu pour déplacer individuellement chaque feuille depuis la sortie de la table de marge 200 jusqu'à la station de réception des feuilles 500, en passant par la station de transformation 300 par presse.A transport device 70 is also provided to move each sheet individually from the output of the feed table 200 to the sheet reception station 500, passing through the processing station 300 per press.

Le dispositif de transport 70 comporte une pluralité de barres transversales munies de pinces, communément appelées barres de pinces 75 qui viennent chacune à leur tour saisir une feuille au niveau de son bord frontal, avant de la tirer successivement dans les différents postes des stations 300, 400, 500 de la machine 1.The transport device 70 comprises a plurality of transverse bars fitted with grippers, commonly called gripper bars 75, which each in turn pick up a sheet at its front edge, before pulling it successively into the various stations of the stations 300, 400, 500 from machine 1.

Les extrémités latérales des barres de pinces 75 sont chacune reliées respectivement à une chaîne latérale formant une boucle, communément appelée train de chaînes 80. Deux trains de chaînes 80 sont ainsi disposés latéralement de chaque côté des barres de pinces 75.The lateral ends of the gripper bars 75 are each connected respectively to a side chain forming a loop, commonly called chain train 80. Two chain trains 80 are thus arranged laterally on each side of the gripper bars 75.

Grâce à un mouvement transmis aux trains de chaînes 80, l'ensemble des barres de pinces 75 va partir d'une position arrêtée, accélérer, atteindre une vitesse maximale, décélérer, puis s'arrêter, en décrivant ainsi un cycle correspondant au déplacement d'une feuille d'une station de travail à la station de travail suivant. Les trains de chaînes 80 se déplacent et s'arrêtent périodiquement de sorte que, durant chaque déplacement, toutes les barres de pinces 75 en prise avec une feuille sont passées d'une station à la station de travail aval adjacente. Chaque station effectue son travail en synchronisme avec ce cycle que l'on appelle communément cycle machine. Les stations de travail démarrent un nouveau travail à chaque début de cycle machine.Thanks to a movement transmitted to the chain trains 80, the set of gripper bars 75 will start from a stopped position, accelerate, reach a maximum speed, decelerate, then stop, thus describing a cycle corresponding to the movement of a sheet from one workstation to the next workstation. The chain trains 80 move and stop periodically so that during each movement, all gripper bars 75 engaged with a sheet have moved from one station to the adjacent downstream work station. Each station performs its work in synchronism with this cycle which is commonly called the machine cycle. Workstations start a new job each time a machine cycle begins.

Le nombre et la nature des stations de traitement dans une machine de façonnage 1 peuvent varier en fonction de la nature et de la complexité des opérations à effectuer sur les feuilles. Dans le cadre de l'invention, la notion de machine de façonnage 1 couvre ainsi un très grand nombre de réalisations du fait de la structure modulaire de ces ensembles. Suivant le nombre, la nature et l'agencement des stations de travail utilisées, il est en effet possible d'obtenir une multitude de machines de traitement différentes. Il est également important de souligner qu'il existe d'autres types de stations de travail que celles évoquées, telles que des stations de gaufrage, refoulage ou telles que des stations de chargement de bandes à estamper pour machine d'estampage ou machine de dorure à chaud (« hot foil stamping » en anglais) où on réalise entre les platines d'une presse, la dépose sur chaque feuille, de motifs à partir d'un film issu d'une ou de plusieurs bandes à estamper. Enfin, il est entendu qu'une même machine de façonnage peut très bien être équipée de plusieurs stations d'un même type.The number and nature of processing stations in a shaping machine 1 can vary depending on the nature and complexity of the operations to be performed on the sheets. In the context of the invention, the notion of shaping machine 1 thus covers a very large number of embodiments due to the modular structure of these assemblies. Depending on the number, nature and layout of the workstations used, it is indeed possible to obtain a multitude of different processing machines. It is also important to point out that there are other types of workstations than those mentioned, such as embossing stations, upsetting or such as stamping strip loading stations for stamping machine or gilding machine hot ("hot foil stamping" in English) where one realizes between the plates of a press, the deposit on each sheet, of patterns from a film resulting from one or more strips to be stamped. Finally, it is understood that the same shaping machine can very well be equipped with several stations of the same type.

Dans la station de réception des feuilles 500, les feuilles transformées s'empilent en pile verticale dans la zone de réception 2, par exemple sur une palette de réception 4 mobile verticalement.In the sheet reception station 500, the converted sheets are stacked in a vertical stack in the reception zone 2, for example on a reception pallet 4 that is movable vertically.

La machine de façonnage 1 comporte en outre au moins un dispositif de rangement 10, agencé dans la station de réception des feuilles 500, pour le rangement des feuilles transformées en piles.The shaping machine 1 further comprises at least one storage device 10, arranged in the sheet receiving station 500, for storing the sheets transformed into stacks.

La machine de façonnage 1 comporte par exemple deux dispositifs de rangement 10 orientés en regard d'une face respective de la pile de feuilles, une butée fixe étant disposée de l'autre côté de la pile pour chaque dispositif de rangement 10. Il y a par exemple un dispositif de rangement 10 frontal et un dispositif de rangement 10 latéral par machine 1.The shaping machine 1 comprises for example two storage devices 10 oriented opposite a respective face of the stack of sheets, a fixed stop being arranged on the other side of the stack for each storage device 10. There is for example a front storage device 10 and a side storage device 10 per machine 1.

Comme on peut le voir sur la Figure 2, le dispositif de rangement 10 comporte une surface de rangement 11 mobile et un dispositif d'actionnement 12 pour déplacer la surface de rangement 11 entre une position de retrait et une position avant verticale dans un mouvement alternatif de va-et-vient pour le rangement des feuilles en pile et entre la position de retrait et une position escamotée pour libérer l'accès à la pile d'éléments en forme de feuilles P.As can be seen on the Figure 2 , the storage device 10 comprises a movable storage surface 11 and an actuating device 12 for moving the storage surface 11 between a retracted position and a vertical forward position in a reciprocating movement back and forth for storage sheets in a stack and between the retracted position and a retracted position to free access to the stack of sheet-shaped elements P.

La surface de rangement 11 présente une surface plane, par exemple formée dans une plaque pouvant être nervurée et/ou ajourée, telle qu'une grille.The storage surface 11 has a flat surface, for example formed in a plate which can be ribbed and/or perforated, such as a grid.

La surface de rangement 11 est mobile selon un mouvement de taquage, c'est à dire selon un mouvement alternatif de va-et-vient entre la position avant verticale (Figures 5A, 8A) et la position de retrait (Figures 6A, 8B). Le mouvement de taquage de la surface de rangement 11 permet de ranger les feuilles après façonnage pour former une pile. Ce mouvement est réalisé à chaque réception de feuille, par exemple de l'ordre de deux ou trois fois par seconde.The storage surface 11 is movable according to a jogging movement, that is to say according to an alternating movement back and forth between the vertical front position ( Fig. 5A , 8A ) and the withdrawal position ( Fig. 6A , 8B ). The jogging movement of the storage surface 11 makes it possible to store the sheets after shaping to form a stack. This movement is carried out each time a sheet is received, for example of the order of two or three times per second.

La surface de rangement 11 est également mobile dans la position escamotée (Figure 7A, 8C) pour libérer l'accès à la pile d'éléments en forme de feuilles P.The storage surface 11 is also movable in the retracted position ( Figure 7A , 8C ) to release access to the stack of P-shaped leaf elements.

Le dispositif d'actionnement 12 comporte des moyens de came configurés pour déplacer la surface de rangement 11 vers le haut en position escamotée, dans une position haute destinée à être située au-dessus du sommet de la pile de feuilles (Figure 8C).The actuating device 12 comprises cam means configured to move the storage surface 11 upwards in the retracted position, in a high position intended to be located above the top of the stack of sheets ( Figure 8C ).

L'accès à la pile de feuilles est ainsi libéré sur toute sa hauteur.Access to the stack of sheets is thus released over its entire height.

Pour cela par exemple, les moyens de came comportent au moins un premier galet suiveur 14 fixé à la surface de rangement 11, à une extrémité de celle-ci (Figures 3 et 4) et au moins un premier profil de commande 15, par exemple ménagé dans un support 16 du dispositif de rangement 10 (Figure 3), coopérant avec le au moins un premier galet suiveur 14 pour guider les déplacements de la surface de rangement 11.For this, for example, the cam means comprise at least a first follower roller 14 fixed to the storage surface 11, at one end of the latter ( Figures 3 and 4 ) and at least a first control profile 15, for example formed in a support 16 of the storage device 10 ( Figure 3 ), cooperating with the at least one first follower roller 14 to guide the movements of the storage surface 11.

Selon un exemple de réalisation, les moyens de came, comprenant le au moins un premier galet suiveur 14 et le au moins un premier profil de commande 15 configurés pour déplacer la surface de rangement 11 entre la position de retrait et la position escamotée vers le haut, sont les mêmes que ceux configurés pour déplacer la surface de rangement 11 entre ladite position de retrait et la position avant verticale dans le mouvement alternatif de va-et-vient pour le rangement des feuilles.According to an exemplary embodiment, the cam means, comprising the at least one first follower roller 14 and the at least one first control profile 15 configured to move the storage surface 11 between the retracted position and the retracted position upwards , are the same as those configured to move the storage surface 11 between said retracted position and the vertical front position in the reciprocating movement back and forth for storing the sheets.

Le guidage des déplacements de la surface de rangement 11 par le au moins un premier galet suiveur 14 et le au moins un premier profil de commande 15, au lieu d'un axe de pivotement articulé, permet d'escamoter la surface de rangement 11 à l'écart et au-dessus de la pile de feuilles. Il est ainsi possible de prévoir de façon simple, robuste et économique, des mouvements adaptés de la surface de rangement 11 en optimisant le design fonctionnel du au moins un premier profil de commande 15, pour dégager un large accès à la pile dans la zone de réception 2 pour le prélèvement aisé d'éléments en forme de feuilles P.The guiding of the movements of the storage surface 11 by the at least one first follower roller 14 and the at least one first control profile 15, instead of an articulated pivot axis, makes it possible to retract the storage surface 11 to away and above the stack of sheets. It is thus possible to provide, in a simple, robust and economical way, suitable movements of the storage surface 11 by optimizing the functional design of at least a first control profile 15, to provide wide access to the battery in the storage area. reception 2 for easy removal of sheet-like elements P.

Le au moins un premier profil de commande 15 est par exemple droit (Figure 3). Une même droite guide alors le au moins un premier galet suiveur 14 entre les trois positions, il n'y a donc pas de discontinuités pour déplacer la surface de rangement 11. Le guidage de la surface de rangement 11 sur le mouvement de taquage représente une petite proportion de ce profil de commande 15 droit, tel qu'inférieur à 10% du premier profil de commande 15. La droite du au moins un premier profil de commande 15 forme par exemple un angle α inférieur à 30° avec l'horizontale.The at least one first control profile 15 is for example straight ( Figure 3 ). A same straight line then guides the at least one first follower roller 14 between the three positions, so there are no discontinuities to move the storage surface 11. The guiding of the storage surface 11 on the jogging movement represents a small proportion of this straight control profile 15, such as less than 10% of the first control profile 15. The straight line of at least one first control profile 15 forms, for example, an angle α of less than 30° with the horizontal.

Les moyens de came comportent en outre au moins un deuxième galet suiveur 17 fixé à la surface de rangement 11 au-dessous du au moins un premier galet suiveur 14 et au moins un deuxième profil de commande 18 coopérant avec le au moins un deuxième galet suiveur 17 (Figure 3).The cam means further comprise at least one second follower roller 17 fixed to the storage surface 11 below the at least one first follower roller 14 and at least one second control profile 18 cooperating with the at least one second follower roller 17 ( Figure 3 ).

Selon un exemple de réalisation, les moyens de came, comprenant le au moins un deuxième galet suiveur 17 et le au moins un deuxième profil de commande 18 configurés pour déplacer la surface de rangement 11 entre la position de retrait et la position escamotée vers le haut, sont les mêmes que ceux configurés pour déplacer la surface de rangement 11 entre ladite position de retrait et la position avant verticale dans le mouvement alternatif de va-et-vient pour le rangement des feuilles.According to an exemplary embodiment, the cam means, comprising the at least one second follower roller 17 and the at least one second control profile 18 configured to move the storage surface 11 between the retracted position and the retracted position upwards , are the same as those configured to move the storage surface 11 between said retracted position and the vertical front position in the reciprocating movement back and forth for storing the sheets.

Une première portion 18a du au moins un deuxième profil de commande 18 est courbe, tel que formant une portion de boucle, pour guider le déplacement de la surface de rangement 11 entre la position de retrait et la position avant verticale. La forme courbe du deuxième profil de commande 18 entraîne un léger recul de la surface de rangement 11 en position de retrait en plus de son pivotement.A first portion 18a of at least a second control profile 18 is curved, such as forming a loop portion, to guide the movement of the storage surface 11 between the retracted position and the vertical front position. The curved shape of the second control profile 18 causes the storage surface 11 to move back slightly in the retracted position in addition to its pivoting.

Une deuxième portion 18b du deuxième profil de commande 18 est droite pour guider le déplacement de la surface de rangement 11 entre la position de retrait et la position escamotée. La première portion 18a et la deuxième portion 18b sont adjacentes et continues pour déplacer la surface de rangement 11 de façon continue entre les trois positions. La droite de la deuxième portion 18b du au moins un deuxième profil de commande 18 forme par exemple un angle β inférieur à 30° avec la verticale.A second portion 18b of the second control profile 18 is straight to guide the movement of the storage surface 11 between the retracted position and the retracted position. The first portion 18a and the second portion 18b are adjacent and continuous to move the storage surface 11 continuously between the three positions. The straight line of the second portion 18b of at least one second control profile 18 forms, for example, an angle β of less than 30° with the vertical.

La deuxième portion 18b du deuxième profil de commande 18 croise la direction du premier profil de commande 15, par exemple à l'extrémité de la petite proportion de ce profil de commande 15.The second portion 18b of the second control profile 18 crosses the direction of the first control profile 15, for example at the end of the small proportion of this control profile 15.

Le deuxième profil de commande 18 peut en outre comporter une troisième portion 18c, située à l'extrémité de la deuxième portion 18b et formant une droite inclinée avec laquelle le deuxième galet suiveur 17 coopère en position escamotée (Figures 3 et 7B).The second control profile 18 may also comprise a third portion 18c, located at the end of the second portion 18b and forming an inclined line with which the second follower roller 17 cooperates in the retracted position ( Figure 3 and 7B ).

Les galets suiveurs 14, 17 sont agencés sur la surface de rangement 11 par exemple pour que leur coopération avec les profils de commande 15, 18 dans la position escamotée déplace la surface de rangement 11 en position haute en formant un angle inférieur à 30° avec l'horizontale.The follower rollers 14, 17 are arranged on the storage surface 11 for example so that their cooperation with the control profiles 15, 18 in the retracted position moves the storage surface 11 in the high position by forming an angle less than 30° with the horizontal.

Ainsi, dans la position avant verticale, la surface de rangement 11 est disposée verticalement et repousse la feuille pour la ranger en pile (Figure 5A, 8A). Dans la position de retrait, la surface de rangement 11 a pivoté et s'est décalée légèrement en retrait de la pile (Figure 6A, 8B). Dans la position escamotée (Figure 7A, 8C), la surface de rangement 11 est relevée en position sensiblement horizontale et dégagée de la pile.Thus, in the vertical front position, the storage surface 11 is arranged vertically and pushes the sheet away to store it in a stack ( Figure 5A , 8A ). In the retracted position, the storage surface 11 has pivoted and shifted slightly back from the stack ( Figure 6A , 8B ). In the retracted position ( Figure 7A , 8C ), the storage surface 11 is raised in a substantially horizontal position and disengaged from the stack.

Le au moins un premier ou deuxième profil de commande 15, 18 sont par exemple formés dans une rainure 19, 20. La troisième portion 18c relie par exemple les deux rainures 19, 20.The at least one first or second control profile 15, 18 are for example formed in a groove 19, 20. The third portion 18c connects for example the two grooves 19, 20.

Le premier profil de commande 15 peut comporter deux butées, par exemple formées aux deux extrémités de la rainure 19 pour les deux positions extrêmes : avant verticale et escamotée.The first control profile 15 may comprise two stops, for example formed at the two ends of the groove 19 for the two extreme positions: vertical front and retracted.

Le au moins un premier profil de commande 15 et le au moins un deuxième profil de commande 18 peuvent être décalés latéralement. On prévoit par exemple de former les profils de commande 15, 18 dans deux rainures 19, 20 d'épaisseurs différentes, le premier profil de commande 15 étant par exemple formé dans la rainure 19 la plus profonde (Figure 3). On empêche ainsi le au moins un premier galet suiveur 14 de coopérer avec le au moins un deuxième profil de commande 18, notamment lorsque le premier galet suiveur 14 suivant le premier profil de commande 15 revient de la position escamotée et croise le deuxième profil de commande 18 pour prendre la position de retrait.The at least one first control profile 15 and the at least one second control profile 18 can be offset laterally. Provision is made, for example, to form the control profiles 15, 18 in two grooves 19, 20 of different thicknesses, the first control profile 15 being for example formed in the deepest groove 19 ( Figure 3 ). This prevents the at least one first follower roller 14 from cooperating with the at least one second control profile 18, in particular when the first follower roller 14 following the first control profile 15 returns from the retracted position and crosses the second control profile 18 to take the withdrawal position.

Le dispositif d'actionnement 12 peut en outre comporter au moins un organe élastique 21, tel qu'un ressort en traction, dont une extrémité 21a est fixe, par exemple fixée au support 16, et l'autre extrémité 21b est fixée à la surface de rangement 11 (Figure 4). L'organe élastique 21 permet d'assurer que les galets suiveurs 14, 17 appuient toujours sur le même côté de la rainure 19, 20 pour coopérer avec le profil de commande 15, 18 respectif.The actuating device 12 may further comprise at least one elastic member 21, such as a traction spring, one end 21a of which is fixed, for example fixed to the support 16, and the other end 21b is fixed to the surface. storage 11 ( Figure 4 ). The elastic member 21 makes it possible to ensure that the follower rollers 14, 17 always press on the same side of the groove 19, 20 to cooperate with the respective control profile 15, 18.

Les moyens de came comportent par exemple deux premiers galets suiveurs 14, chacun fixé à une extrémité respective de la surface de rangement 11 et deux premiers profils de commande 15 coopérant avec un premier galet suiveur 14 respectif. En outre, les moyens de came peuvent également comporter deux deuxièmes galets suiveurs 17 et deux deuxièmes profils de commande 18 coopérant avec un deuxième galet suiveur 17 respectif. Les deuxièmes galets suiveurs 17 sont chacun fixé à une extrémité respective de la surface de rangement 11 au-dessous d'un premier galet suiveur 14.The cam means comprise for example two first follower rollers 14, each fixed to a respective end of the storage surface 11 and two first control profiles 15 cooperating with a respective first follower roller 14. In addition, the cam means may also comprise two second follower rollers 17 and two second control profiles 18 cooperating with a second follower roller 17 respectively. The second follower rollers 17 are each fixed to a respective end of the storage surface 11 below a first follower roller 14.

Les premiers profils de commande 15 et les deuxièmes profils de commande 18 sont par exemple ménagés dans deux supports 16 qui sont agencés latéralement, de chaque côté et à chaque extrémité de la surface de rangement 11 (Figure 2).The first control profiles 15 and the second control profiles 18 are for example formed in two supports 16 which are arranged laterally, on each side and at each end of the storage surface 11 ( Figure 2 ).

L'entrainement de la surface de rangement 11 est par exemple réalisé au moyen d'au moins un actionneur 22.The drive of the storage surface 11 is for example carried out by means of at least one actuator 22.

Le dispositif d'actionnement 12 comporte par exemple deux actionneurs 22 chacun relié à une extrémité de la surface de rangement 11 (Figure 2).The actuating device 12 comprises for example two actuators 22 each connected to one end of the storage surface 11 ( Figure 2 ).

La tige du au moins un actionneur 22 est par exemple reliée à un point d'actionnement situé au dos du premier galet suiveur 14 (Figure 4).The rod of at least one actuator 22 is for example connected to an actuation point located on the back of the first follower roller 14 ( Figure 4 ).

Selon un exemple de réalisation, le au moins un actionneur 22 comporte un double vérin pneumatique configuré pour déplacer la surface de rangement 11 entre la position de retrait et la position avant verticale sur une petite course et pour déplacer la surface de rangement 11 entre la position de retrait et la position escamotée sur une grande course.According to an exemplary embodiment, the at least one actuator 22 comprises a double pneumatic cylinder configured to move the storage surface 11 between the retracted position and the vertical front position over a short stroke and to move the storage surface 11 between the position withdrawal and the retracted position on a long stroke.

On va maintenant décrire un exemple de fonctionnement d'un dispositif de rangement 10 dans une zone de réception 2 d'une station de réception des feuilles 500.We will now describe an example of the operation of a storage device 10 in a reception area 2 of a sheet reception station 500.

En production, la surface de rangement 11 est mobile selon le mouvement alternatif de va-et-vient entre la position avant verticale (Figures 5A, 5B, 8A) et la position de retrait (Figures 6A, 6B, 8B) pour ranger les feuilles une par une après façonnage pour former une pile.In production, the storage surface 11 is movable according to the reciprocating movement back and forth between the vertical front position ( Figures 5A, 5B , 8A ) and the withdrawal position ( Figures 6A, 6B , 8B ) to arrange the sheets one by one after shaping to form a stack.

Le guidage de la surface de rangement 11 sur le mouvement de taquage est réalisé par le mouvement de va-et-vient des premiers galets suiveurs 14 contre les petites portions des premiers profils de commande 15 droits et des seconds galets suiveurs 17 contre les premières portions 18a courbes des deuxièmes profils de commande 18.The guiding of the storage surface 11 on the jogging movement is achieved by the reciprocating movement of the first follower rollers 14 against the small portions of the first straight control profiles 15 and of the second follower rollers 17 against the first portions 18a curves of the second control profiles 18.

Ainsi, dans la position avant verticale, la surface de rangement 11 est disposée verticalement et pousse la feuille pour la positionner en pile (Figure 5A, 5B, 8A). Dans la position de retrait, la surface de rangement 11 a pivoté et s'est décalée légèrement en retrait de la pile (Figure 6A, 6B, 8B).Thus, in the vertical front position, the storage surface 11 is arranged vertically and pushes the sheet to position it in a stack ( Figure 5A, 5B , 8A ). In the retracted position, the storage surface 11 has pivoted and shifted slightly back from the stack ( Figure 6A, 6B , 8B ).

Lorsque l'utilisateur souhaite prélever une feuille transformée, il commande les actionneurs 22 sur la grande course pour basculer la surface de rangement 11 dans la position escamotée (Figure 7A, 7B, 8C) pour libérer l'accès de la pile d'éléments en forme de feuilles P.When the user wishes to take a transformed sheet, he controls the actuators 22 on the long stroke to tilt the storage surface 11 into the retracted position ( Figure 7A, 7B , 8C ) to release access to the stack of P-shaped leaf elements.

Les premiers galets suiveurs 14 poursuivent leurs déplacements sur les grandes portions des premiers profils de commande 15 droits sans discontinuité et les deuxièmes galets suiveurs 17 poursuivent leurs déplacements sur les deuxièmes portions 18b droites des deuxièmes profils de commande 18. La surface de rangement 11 est ainsi déplacée dans la position escamotée, par exemple en formant un angle inférieur à 30° avec l'horizontale. Dans cette position escamotée (Figure 7A, 7B, 8C), la surface de rangement 11 est relevée en position haute, sensiblement horizontale au-dessus de la pile. Entre la position de retrait et la position escamotée, la surface de rangement 11 a pivoté et a reculé. L'escamotage de la surface de rangement 11 à l'écart et au-dessus de la pile libère une large zone d'accès pour la prise d'une feuille de contrôle.The first follower rollers 14 continue their movements on the large portions of the first straight control profiles 15 without interruption and the second follower rollers 17 continue their movements on the second straight portions 18b of the second control profiles 18. The storage surface 11 is thus moved into the retracted position, for example by forming an angle of less than 30° with the horizontal. In this retracted position ( Figure 7A, 7B , 8C ), the storage surface 11 is raised in the high position, substantially horizontal above the stack. Between the retracted position and the retracted position, the storage surface 11 has pivoted and moved back. The retraction of the storage surface 11 away from and above the stack releases a large access area for taking a control sheet.

Après prélèvement de l'échantillon, la surface de rangement 11 est commandée en position de retrait. Les galets suiveurs 14, 17 suivent alors les profils de commande 15, 18 en sens inverse. Les premiers galets suiveurs 14 ne peuvent pas suivre les deuxièmes profils de commande 18 lorsqu'ils les croisent du fait des différences d'épaisseurs des rainures 19, 20.After taking the sample, the storage surface 11 is controlled in the retracted position. The follower rollers 14, 17 then follow the control profiles 15, 18 in the opposite direction. The first follower rollers 14 cannot follow the second control profiles 18 when they cross them due to the differences in thickness of the grooves 19, 20.
