Definitions

  • the present invention relates to a device for loading insert sheets for inserting between stacks of poses in a reception area of a station for receiving the poses.
  • the present invention also relates to a station receiving station, a machine for processing sheet-like elements and a method of transporting an insert sheet in a reception area of a station receiving station.
  • the separation of the poses consists, after shaping and complete ejection of the waste, to break the attachment points between the poses of a sheet by means of a male upper tool and a female lower tool mounted vertically one above the other in the leaf receiving area.
  • the upper tool consists of pushing elements slightly smaller than the perimeter of the poses.
  • the lower tool consists of a grid whose mesh shape generally corresponds to the perimeter of the poses. The poses fall through these meshes and stack in vertical stacks in the reception area.
  • Inserting involves placing an insert sheet, such as a full sheet, between stacks of poses. So that this inserting can be carried out without requiring a concomitant shutdown of the production unit, a device commonly known as a non-stop reception grid is used.
  • an insert sheet is grabbed from a stack of insert sheets arranged near the reception area.
  • the insert sheet is then dropped onto the non-stop pose reception grid.
  • the non-stop receiving grid carrying the insert sheet then moves under the lower blanking tool.
  • the non-stop receiving grid returns over the stack of insert sheets to receive a new sheet. Leaving the reception area, the grid crosses the teeth of a comb which has pivoted into the retaining position to retain the insert sheet and thus the poses stacked on this insert sheet, in the reception area.
  • the non-stop reception grid thus allows the deposit of an insert sheet between the stacks of poses and the support of the poses during the evacuation of the stacks of complete poses without stopping production.
  • the document DE 195 16 023 A1 describes an inserting device which lifts an insert sheet on a stack using a pivoting arm fitted with a suction cup and then deposits it on an inserting grid when the latter leaves the zone for receiving the poses .
  • the suction cup device is then moved aside in order to allow the grid to rise, then to be inserted in the zone for receiving the poses.
  • the grid then lowers at a speed that corresponds to the rate of production of the poses. When the grid reaches a low position, it leaves the zone for receiving the blanks to receive a new insert sheet.
  • the insert sheet remains in the poses reception zone thanks to a vertical grid which retains it.
  • the document does not specify how the insert sheet is fixed and detached from the insert grid, nor how its position on the grid is adjusted.
  • the displacement of the grid or the tray carrying the insert sheet towards the reception area must be carried out quickly to insert the insert sheet as quickly as possible between the last deposited pose on the top of the stack and the next.
  • the relatively large stroke to be carried out and the high production rates which may require, for the grid or the tray, displacement speeds of the order of 1 m / sec, keeping the insert sheet in position. turns out to be tricky.
  • the accelerations and decelerations may be too sudden to properly entrain the insert sheet. It may happen that when it arrives in the reception area, the insert sheet is offset or skewed and thus finds itself badly positioned between the stack poses.
  • One of the aims of the present invention is to propose an improved device for loading inset sheets making it possible to ensure the correct positioning of the inset sheet during its transport in the reception area.

Depending on the number, nature and arrangement of the workstations used, it is indeed possible to obtain a multitude of different processing machines.

La présente invention concerne également une station de réception des poses, une machine de traitement d'éléments en forme de feuilles et un procédé de transport d'une feuille d'encart dans une zone de réception d'une station de réception des poses.The present invention relates to a device for loading insert sheets for inserting between stacks of poses in a reception area of a station for receiving the poses. The present invention also relates to a station receiving station, a machine for processing sheet-like elements and a method of transporting an insert sheet in a reception area of a station receiving station.

Dans les stations de réception, la séparation des poses consiste, après façonnage et éjection complète des déchets, à rompre les points d'attache entre les poses d'une feuille au moyen d'un outil supérieur mâle et d'un outil inférieur femelle montés verticalement l'un au-dessus de l'autre dans la zone de réception des feuilles. L'outil supérieur est constitué d'éléments pousseurs légèrement plus petits que le pourtour des poses. L'outil inférieur est constitué d'une grille dont la forme des mailles correspond généralement au pourtour des poses. Les poses tombent à travers ces mailles et s'empilent en piles verticales dans la zone de réception.In the receiving stations, the separation of the poses consists, after shaping and complete ejection of the waste, to break the attachment points between the poses of a sheet by means of a male upper tool and a female lower tool mounted vertically one above the other in the leaf receiving area. The upper tool consists of pushing elements slightly smaller than the perimeter of the poses. The lower tool consists of a grid whose mesh shape generally corresponds to the perimeter of the poses. The poses fall through these meshes and stack in vertical stacks in the reception area.

Pour former des piles de poses séparées et stables sous ces outils, sur la palette de réception de la station, un encartage périodique d'une feuille de stabilisation s'avère nécessaire. L'encartage consiste à disposer une feuille d'encart, telle qu'une feuille pleine, entre des piles de poses. Pour que cet encartage puisse être effectué sans nécessiter un arrêt concomitant de l'unité de production, on utilise un dispositif communément appelé grille de réception non-stop.To form stacks of separate and stable poses under these tools, on the pallet for receiving the station, periodic insertion of a stabilization sheet is necessary. Inserting involves placing an insert sheet, such as a full sheet, between stacks of poses. So that this inserting can be carried out without requiring a concomitant shutdown of the production unit, a device commonly known as a non-stop reception grid is used.

Pour effectuer une manœuvre d'encartage, une feuille d'encart est saisie sur une pile de feuilles d'encart disposée à proximité de la zone de réception. La feuille d'encart est ensuite lâchée sur la grille de réception non-stop de poses. La grille de réception non-stop portant la feuille d'encart se déplace ensuite sous l'outil inférieur de séparation des poses. Puis, la grille de réception non-stop retourne au-dessus de la pile de feuilles d'encart recevoir une nouvelle feuille. En quittant la zone de réception, la grille croise les dents d'un peigne qui a pivoté en position de retenue pour retenir la feuille d'encart et ainsi les poses empilées sur cette feuille d'encart, dans la zone de réception. La grille de réception non-stop permet ainsi la dépose d'une feuille d'encart entre les piles de poses et le soutien des poses pendant l'évacuation des piles de poses complètes sans arrêt de la production.To carry out an inserting maneuver, an insert sheet is grabbed from a stack of insert sheets arranged near the reception area. The insert sheet is then dropped onto the non-stop pose reception grid. The non-stop receiving grid carrying the insert sheet then moves under the lower blanking tool. Then, the non-stop receiving grid returns over the stack of insert sheets to receive a new sheet. Leaving the reception area, the grid crosses the teeth of a comb which has pivoted into the retaining position to retain the insert sheet and thus the poses stacked on this insert sheet, in the reception area. The non-stop reception grid thus allows the deposit of an insert sheet between the stacks of poses and the support of the poses during the evacuation of the stacks of complete poses without stopping production.

On connait également un dispositif de chargement muni d'un plateau mobile pour réaliser uniquement les opérations d'encartage, le soutien des poses pendant l'évacuation des piles sans arrêt de la production étant réalisé par d'autres moyens.There is also known a loading device provided with a movable plate for carrying out only the inserting operations, the support of the poses during the evacuation of the batteries without stopping the production being carried out by other means.

Le document DE 195 16 023 A1 décrit un dispositif d'encartage qui soulève une feuille d'encart sur une pile à l'aide d'une bras pivotant munis d'une ventouse puis la dépose sur un grille d'encartage lorsque celle-ci quitte la zone de réception des poses. Le dispositif de ventouse est ensuite écarté afin de permettre à la grille de monter, puis de s'insérer dans la zone de réception des poses. La grille s'abaisse ensuite à une vitesse qui correspond au rythme de production des poses. Lorsque la grille atteint une position basse, elle quitte la zone de zone de réception des poses pour recevoir une nouvelle feuille d'encart. La feuille d'encart reste dans la zone de réception des poses grâce à une grille verticale qui la retient. Le document ne spécifie pas comment la feuille d'encart est solidarisée et désolidarisée de la grille d'encartage, ni comment sa position sur la grille est réglée.The document DE 195 16 023 A1 describes an inserting device which lifts an insert sheet on a stack using a pivoting arm fitted with a suction cup and then deposits it on an inserting grid when the latter leaves the zone for receiving the poses . The suction cup device is then moved aside in order to allow the grid to rise, then to be inserted in the zone for receiving the poses. The grid then lowers at a speed that corresponds to the rate of production of the poses. When the grid reaches a low position, it leaves the zone for receiving the blanks to receive a new insert sheet. The insert sheet remains in the poses reception zone thanks to a vertical grid which retains it. The document does not specify how the insert sheet is fixed and detached from the insert grid, nor how its position on the grid is adjusted.

Afin de ne pas abaisser la quantité de poses produites, le déplacement de la grille ou du plateau portant la feuille d'encart vers la zone de réception doit être réalisé rapidement pour intercaler le plus rapidement possible la feuille d'encart entre la dernière pose déposée sur le haut de la pile et la suivante. Etant donné la course relativement grande à effectuer et les cadences élevées de production qui peuvent exiger, pour la grille ou le plateau, des vitesses de déplacement de l'ordre de 1 m/sec, le maintien en position de la feuille d'encart s'avère délicat. En particulier, les accélérations et décélérations peuvent être trop brusques pour entrainer correctement la feuille d'encart. Il peut arriver qu'à son arrivée dans la zone de réception, la feuille d'encart soit décalée ou orientée de travers et se retrouve ainsi mal positionnée entre les poses de la pile.In order not to lower the quantity of poses produced, the displacement of the grid or the tray carrying the insert sheet towards the reception area must be carried out quickly to insert the insert sheet as quickly as possible between the last deposited pose on the top of the stack and the next. Given the relatively large stroke to be carried out and the high production rates which may require, for the grid or the tray, displacement speeds of the order of 1 m / sec, keeping the insert sheet in position. turns out to be tricky. In particular, the accelerations and decelerations may be too sudden to properly entrain the insert sheet. It may happen that when it arrives in the reception area, the insert sheet is offset or skewed and thus finds itself badly positioned between the stack poses.

Un des buts de la présente invention est de proposer un dispositif de chargement de feuilles d'encart amélioré permettant d'assurer le positionnement correct de la feuille d'encart lors de son transport dans la zone de réception.One of the aims of the present invention is to propose an improved device for loading inset sheets making it possible to ensure the correct positioning of the inset sheet during its transport in the reception area.

Sur ces figures, les éléments identiques portent les mêmes numéros de référence. Les réalisations suivantes sont des exemples. Bien que la description se réfère à un ou plusieurs modes de réalisation, ceci ne signifie pas nécessairement que chaque référence concerne le même mode de réalisation, ou que les caractéristiques s'appliquent seulement à un seul mode de réalisation. De simples caractéristiques de différents modes de réalisation peuvent également être combinées ou interchangées pour fournir d'autres réalisations.In these figures, identical elements have the same reference numbers. The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the characteristics apply only to a single embodiment. Simple features of different embodiments can also be combined or interchanged to provide other embodiments.

On désigne les directions longitudinale, verticale et transversale indiquées sur la figure 2 par le trièdre (L, V, T). La direction transversale T est la direction perpendiculaire à la direction longitudinale de déplacement D d'une feuille, tel qu'illustré par la flèche D sur les figures 1 et 2. Le plan horizontal correspond au plan (L, T).We designate the longitudinal, vertical and transverse directions indicated on the figure 2 by the trihedron (L, V, T). The transverse direction T is the direction perpendicular to the longitudinal direction of movement D of a sheet, as illustrated by the arrow D on the figures 1 and 2 . The horizontal plane corresponds to the (L, T) plane.

On définit les termes amont et aval en référence à la direction longitudinale de déplacement D. 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 D. The sheets move from upstream to downstream, generally following the main longitudinal axis of the machine, in a movement clocked by periodic stops.

Les termes « éléments plats » 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 “flat elements” and “sheets” will be considered equivalent, and will relate to elements composed 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 leaves" very generally designate any print medium in the form of leaves such as, for example , sheets of cardboard, paper, plastic, etc.

La figure 1 représente un exemple de machine de traitement 1 pour la transformation de feuilles. Cette machine de traitement 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 pour la découpe des feuilles, telle que comprenant une presse à platines 301, une station d'éjection des déchets 400, une station de réception des poses 500 où les feuilles transformées sont reconditionnées en pile et les déchets de feuilles découpées sont évacués.The figure 1 shows an example of processing machine 1 for processing sheets. This processing 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 margin table 200, a processing station 300 for cutting the sheets, such as comprising a plate press 301, a waste ejection station 400, a station for receiving the poses 500 where the transformed sheets are repackaged in a pile and the cut sheet waste is disposed of.

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 plate and a lower movable plate of the press 301 for cutting the sheets according to a matrix corresponding to the developed shape which is wishes to obtain, for example in order to obtain a plurality of boxes of a given shape. The movable stage rises and falls successively 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 poses 500, en passant par la station de transformation 300 par presse.A transport device 70 is also provided for individually moving each sheet from the output of the margin table 200 to the station receiving station 500, passing through the transformer station 300 by 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 provided with grippers, commonly called gripper bars 75 which each come in their turn to grab a sheet at its front edge, before drawing it successively in the various stations of the stations 300, 400, 500 of machine 1.

Les extrémités 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 ends of the clamp 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 clamp 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 sont en position initiale pour démarrer un nouveau travail à chaque début de cycle machine.Thanks to a movement transmitted to the chains of chains 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 the gripper bars 75 engaged with a sheet are passed from one station to the adjacent downstream work station. Each station performs its work in synchronism with this cycle which is commonly called machine cycle. The workstations are in the initial position to start a new job at the start of each machine cycle.

Le nombre et la nature des stations de traitement dans une machine de traitement 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 traitement 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 telle 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 traitement peut très bien être équipée de plusieurs stations d'un même type.The number and nature of the processing stations in a processing machine 1 can vary depending on the nature and the complexity of the operations to be performed on the sheets. In the context of the invention, the concept of processing machine thus covers a very large number of embodiments due to the modular structure of these assemblies. Depending on the number, nature and arrangement of the workstations used, it is indeed possible to obtain a multitude of different processing machines. It is also important to underline that there are other types of work stations than those mentioned, such as embossing, upsetting stations or such as stations for loading stripes for stamping for stamping machine or foil stamping machine. hot foil stamping in which one carries out between the platens of a press, the deposit on each sheet, of patterns from a film from one or more bands to be stamped. Finally, it is understood that the same processing machine may very well be equipped with several stations of the same type.

Dans la station de réception des poses 500, après façonnage dans la station de transformation 300 et éjection des déchets dans la station d'éjection des déchets 400, les points d'attache entre les poses d'une feuille sont rompus au moyen d'un outil supérieur mâle et d'un outil inférieur femelle montés verticalement l'un au-dessus de l'autre dans une zone de réception 2 représentée sur la figure 2.In the poses reception station 500, after shaping in the transformation station 300 and ejection of the waste in the waste ejection station 400, the points of attachment between the poses of a sheet are broken by means of a male upper tool and a female lower tool mounted vertically one above the other in a receiving zone 2 shown in the figure 2 .

L'outil supérieur est constitué d'éléments pousseurs légèrement plus petits que le pourtour des poses. L'outil inférieur 3 est formé d'une grille dont la forme des mailles correspond généralement au pourtour des poses. Dans l'exemple, l'outil inférieur 3 comporte des barres longitudinales et transversales formant une grille à mailles carrées. Les poses tombent à travers les mailles de cette grille et s'empilent en piles verticales dans la zone de réception 2 sur une palette de réception 4 portée par un cadre 501 de la station 500, mobile verticalement.The upper tool consists of pushing elements slightly smaller than the perimeter of the poses. The lower tool 3 is formed of a grid, the mesh shape of which generally corresponds to the periphery of the poses. In the example, the lower tool 3 comprises longitudinal and transverse bars forming a grid with square meshes. The poses fall through the meshes of this grid and stack in vertical stacks in the reception zone 2 on a reception pallet 4 carried by a frame 501 of the station 500, vertically movable.

La station de réception des poses 500 comporte un dispositif de chargement 10 de feuilles d'encart, fixé au bâti de la machine 1. L'encartage consiste à disposer une feuille d'encart, telle qu'une feuille pleine, entre des piles de poses dans la zone de réception 2.The poses reception station 500 includes a device 10 for loading inset sheets, fixed to the frame of the machine 1. Insetting consists in placing an inset sheet, such as a full sheet, between stacks of poses in the reception area 2.

Le dispositif de chargement 10 comporte un bac 11 de réserve de feuilles d'encart, un chariot mobile 12, un dispositif de saisie 13 de feuilles d'encart et un peigne de retenue 14 pivotant.The loading device 10 comprises a container 11 for reserving insert sheets, a mobile carriage 12, a device 13 for gripping insert sheets and a pivoting retaining comb 14.

Le bac 11 comporte un logement 9 destiné à recevoir une pile de feuilles d'encart. Le bac 11 est mobile en translation dans la direction transversale T pour pouvoir être rechargé par un opérateur à travers une fenêtre du bâti 16 du dispositif de chargement 10, depuis un côté du dispositif de chargement 10. Le bac 11 peut être monté sur deux glissières transversales 15 et comporter une poignée, tel un tiroir.The tray 11 includes a housing 9 intended to receive a stack of insert sheets. The container 11 is movable in translation in the transverse direction T so that it can be recharged by an operator through a window of the frame 16 of the loading device 10, from one side of the loading device 10. The container 11 can be mounted on two slides 15 and include a handle, such as a drawer.

Le chariot mobile 12 est mobile en translation dans la direction longitudinale de déplacement des feuilles D entre une position rentrée au-dessus du bac 11 pour recevoir une feuille d'encart (figure 3) et une position sortie pour l'insertion de la feuille d'encart dans la zone de réception 2 (figure 2).The movable carriage 12 is movable in translation in the longitudinal direction of movement of the sheets D between a retracted position above the container 11 to receive an insert sheet ( figure 3 ) and an extended position for inserting the insert sheet into the receiving area 2 ( figure 2 ).

Comme on peut le voir sur la figure 5, le chariot mobile 12 comporte au moins une traverse 26 et une pluralité de barres longitudinales 27a, 27b fixées et portées par la traverse 26. Le chariot mobile 12 comporte par exemple un nombre de barres longitudinales 27a, 27b compris entre 6 et 25, le nombre étant adapté au format des feuilles d'encart.As we can see on the figure 5 , the mobile carriage 12 comprises at least one cross 26 and a plurality of longitudinal bars 27a, 27b fixed and carried by the cross 26. The mobile carriage 12 comprises for example a number of longitudinal bars 27a, 27b between 6 and 25, the number being adapted to the format of the insert sheets.

Les extrémités latérales de la traverse 26 sont par exemple munies de galets rotatifs 28 coopérant avec des glissières longitudinales 17 portées par le bâti 16. Le chariot mobile 12 comporte par exemple six galets rotatifs 28 à chaque extrémité de la traverse 26 (cinq rotatifs autour d'un axe transversal pour le guidage longitudinal et un rotatif autour d'un axe vertical pour le guidage latéral). L'entrainement en translation du chariot mobile 12 peut être assuré par deux chaines 18 ou courroie(s) ou crémaillère(s), entrainées par exemple par un moteur (non visible), piloté par une unité de contrôle 7 de la machine de traitement 1, pour programmer un encartage lorsque la pile de poses atteint la hauteur souhaitée. Les chaines 18 sont reliées par un élément de fixation 29 respectif porté par une extrémité respective de la traverse 26.The lateral ends of the cross member 26 are for example provided with rotary rollers 28 cooperating with longitudinal slides 17 carried by the frame 16. The movable carriage 12 comprises for example six rotary rollers 28 at each end of the cross member 26 (five rotary around '' a transverse axis for longitudinal guidance and a rotary around a vertical axis for lateral guidance). The translational carriage of the mobile carriage 12 can be provided by two chains 18 or belt (s) or rack (s), driven for example by a motor (not visible), controlled by a control unit 7 of the processing machine 1, for programming an insert when the stack of poses reaches the desired height. The chains 18 are connected by a respective fixing element 29 carried by a respective end of the crosspiece 26.

Le peigne de retenue 14 comporte des dents régulièrement espacées dans la direction transversale. Le peigne 14 est monté pivotant autour d'un axe transversal interposé entre le bac 11 et la zone de réception 2 des poses. Le peigne 14 est pivotant entre une position de retenue dans laquelle les dents du peigne 14 passent entre les barres longitudinales 27a, 27b du chariot mobile 12 et une position libérée dans laquelle les dents du peigne 14 sont escamotées.The retaining comb 14 has teeth regularly spaced in the transverse direction. The comb 14 is pivotally mounted around a transverse axis interposed between the tray 11 and the reception area 2 of the poses. The comb 14 is pivotable between a retaining position in which the teeth of the comb 14 pass between the longitudinal bars 27a, 27b of the movable carriage 12 and a released position in which the teeth of the comb 14 are retracted.

Le dispositif de saisie 13 de feuilles d'encart est agencé au-dessus du chariot mobile 12 en position rentrée (figure 3). Le dispositif de saisie 13 est configuré pour soulever une feuille d'encart dans le bac 11 de réserve de feuille d'encart et pour déposer la feuille d'encart soulevée sur le chariot mobile 12.The input device 13 for insert sheets is arranged above the movable carriage 12 in the retracted position ( figure 3 ). The gripping device 13 is configured to lift an insert sheet in the insert sheet reserve tray 11 and to deposit the lifted insert sheet on the mobile carriage 12.

Il comporte un élément d'aspiration 20 configuré pour saisir une feuille d'encart et un support 21 monté sur le bâti 16 pour déplacer l'élément d'aspiration 20 entre une position basse vers la pile de feuilles d'encart et une position haute à l'écart de la pile de feuilles d'encart. Le support 21 peut être monté en coulissement longitudinal sur le bâti 16 pour adapter le positionnement longitudinal de la zone de saisie au format des feuilles d'encart.It comprises a suction element 20 configured to grip an insert sheet and a support 21 mounted on the frame 16 to move the suction element 20 between a low position towards the stack of insert sheets and a high position away from the stack of inset sheets. The support 21 can be mounted in longitudinal sliding on the frame 16 to adapt the longitudinal positioning of the entry area to the format of the insert sheets.

L'élément d'aspiration 20 est relié à une source de vide, telle qu'une pompe à vide ou un dispositif Venturi, par exemple au moyen de flexibles. Selon un exemple de réalisation, l'élément d'aspiration 20 comporte une barre d'aspiration transversale munie de ventouses 23 pivotantes.The suction element 20 is connected to a vacuum source, such as a vacuum pump or a Venturi device, for example by means of hoses. According to an exemplary embodiment, the suction element 20 comprises a transverse suction bar provided with pivoting suction cups 23.

Au moins une barre longitudinale 27a du chariot mobile 12 comporte un canal d'aspiration 35 débouchant par au moins un orifice d'aspiration 30 sur la face de la barre longitudinale 27a destinée à recevoir une feuille d'encart, c'est-à-dire la face supérieure lorsque le chariot mobile 12 est monté dans la station de réception des poses 500.At least one longitudinal bar 27a of the movable carriage 12 has a suction channel 35 opening out through at least one suction orifice 30 on the face of the longitudinal bar 27a intended to receive an insert sheet, that is to say say the upper face when the movable carriage 12 is mounted in the pose receiving station 500.

Le canal d'aspiration 35 est configuré pour être relié à une source de vide 31 pour le maintien par aspiration de la feuille d'encart transportée par le chariot mobile 12. La feuille d'encart peut ainsi être maintenue en position sur le chariot mobile 12 pour son transport vers la zone de réception 2, malgré la vitesse rapide de déplacement du chariot mobile 12.The suction channel 35 is configured to be connected to a vacuum source 31 for holding by suction the insert sheet transported by the movable carriage 12. The insert sheet can thus be held in position on the movable carriage 12 for its transport to the reception area 2, despite the rapid speed of movement of the mobile carriage 12.

Par exemple, le chariot mobile 12 comporte au moins deux barres longitudinales 27a présentant chacune un canal d'aspiration 35 débouchant par au moins un orifice d'aspiration 30. La feuille d'encart peut ainsi être maintenue au minimum en deux points, ce qui permet d'éviter le décalage angulaire de la feuille d'encart, notamment pour des feuilles de petit format.For example, the movable carriage 12 comprises at least two longitudinal bars 27a each having a suction channel 35 opening out through at least one suction orifice 30. The insert sheet can thus be kept at a minimum at two points, which makes it possible to avoid the angular offset of the insert sheet, in particular for small sheets.

On prévoit par exemple qu'une même barre longitudinale 27a présente une pluralité d'orifices d'aspiration 30 régulièrement espacés, par exemple six.Provision is made, for example, for the same longitudinal bar 27a to have a plurality of regularly spaced suction ports 30, for example six.

Les orifices d'aspiration 30 peuvent être agencés dans une zone centrale du chariot mobile 12, pour qu'ils soient recouverts par la feuille d'encart pour tous les formats de feuille. On évite ainsi à des orifices d'aspiration 30 d'aspirer du vide, ce qui pourrait empêcher aux autres orifices d'aspiration 30 de fonctionner correctement.The suction ports 30 can be arranged in a central area of the movable carriage 12, so that they are covered by the insert sheet for all sheet formats. This prevents the suction ports 30 from sucking in vacuum, which could prevent the other suction ports 30 from functioning properly.

Par exemple, deux premières barres longitudinales 27a sont au moins espacées d'une deuxième barre longitudinale 27b. Les deux premières barres longitudinales 27a sont par exemple espacées de trois deuxièmes barres longitudinales 27b. Les premières barres longitudinales 27a sont par exemple identiques pour agencer symétriquement les orifices d'aspiration 30 des différentes barres longitudinales 27a.For example, two first longitudinal bars 27a are at least spaced from a second longitudinal bar 27b. The first two longitudinal bars 27a are for example spaced from three second longitudinal bars 27b. The first longitudinal bars 27a are for example identical to arrange symmetrically the suction orifices 30 of the different longitudinal bars 27a.

La source de vide 31, telle qu'une pompe à vide ou un dispositif Venturi, est raccordée au chariot mobile 12, par exemple au moyen de flexibles permettent d'adapter la longueur des canalisations à la position du chariot mobile 12. La source de vide 31 est contrôlée par l'unité de contrôle 7 pour établir une basse pression d'aspiration dans les orifices d'aspiration 30 ou pour arrêter l'aspiration dans ces derniers.The vacuum source 31, such as a vacuum pump or a Venturi device, is connected to the mobile carriage 12, for example by means of hoses make it possible to adapt the length of the pipes to the position of the mobile carriage 12. The source of vacuum 31 is controlled by the control unit 7 to establish a low suction pressure in the suction ports 30 or to stop the suction in the latter.

Dans l'exemple, la source de vide 31 est un dispositif Venturi fixé sous le chariot mobile 12 (figure 5). Une canalisation flexible (non représentée) comporte une première extrémité raccordée à la source de vide 31 et une deuxième extrémité raccordée à une alimentation d'air. La canalisation flexible présente donc une extrémité fixée au bâti 16 et une extrémité mobile, se déplaçant avec le va-et-vient du chariot 12.In the example, the vacuum source 31 is a Venturi device fixed under the movable carriage 12 ( figure 5 ). A flexible pipe (not shown) has a first end connected to the vacuum source 31 and a second end connected to an air supply. The flexible pipe therefore has an end fixed to the frame 16 and a movable end, moving with the back and forth of the carriage 12.

Selon un exemple de réalisation, les barres longitudinales 27a présentant au moins un orifice d'aspiration 30 sont des profilés creux, tel qu'un tube à section rectangulaire (ou carrée) et dont l'intérieur forme le canal d'aspiration 35.According to an exemplary embodiment, the longitudinal bars 27a having at least one suction orifice 30 are hollow profiles, such as a tube with rectangular (or square) section and the interior of which forms the suction channel 35.

Les canaux d'aspiration 35 des barres longitudinales 27a peuvent être reliés à la traverse 26 du chariot mobile 12, prévue également creuse. La source de vide 31 peut alors être raccordée à une extrémité de la traverse 26. Le chariot mobile 12 fait ainsi office de canalisation fluidique pour convoyer la basse pression d'aspiration aux différents orifices d'aspiration 30.The suction channels 35 of the longitudinal bars 27a can be connected to the crosspiece 26 of the movable carriage 12, also provided hollow. The vacuum source 31 can then be connected to one end of the cross-member 26. The mobile carriage 12 thus acts as a fluid line for conveying the low suction pressure to the various suction orifices 30.

Le au moins un canal d'aspiration 35 peut également être configuré pour être relié à une source de gaz, telle qu'une source d'air, pour souffler par le au moins un orifice d'aspiration 30 afin de faciliter la libération de la feuille d'encart une fois celle-ci arrivée à destination dans la zone de réception 2.The at least one suction channel 35 can also be configured to be connected to a gas source, such as an air source, for blowing through the at least one suction port 30 in order to facilitate the release of the insert sheet once it has arrived at its destination in reception area 2.

Selon un exemple de réalisation visible sur la vue en coupe de la figure 6, la traverse 26 comporte une embase 26a et une plaque de fermeture 26b, fermant l'embase 26a. Un canal transversal 26c est ménagé dans l'embase 26a et débouche à une extrémité latérale de la traverse 26 à laquelle la source de vide 31 (et la source de gaz le cas échéant) peut être raccordée (l'extrémité située à gauche sur la figure 5). Au moins un trou est ménagé dans la plaque de fermeture 26b, le trou communiquant avec le canal d'aspiration 35 des barres longitudinales 27a.According to an exemplary embodiment visible in the sectional view of the figure 6 , the crosspiece 26 comprises a base 26a and a closure plate 26b, closing the base 26a. A transverse channel 26c is formed in the base 26a and opens at a lateral end of the crosspiece 26 to which the vacuum source 31 (and the gas source if applicable) can be connected (the end located on the left on the figure 5 ). At least one hole is made in the closing plate 26b, the hole communicating with the suction channel 35 of the longitudinal bars 27a.

Selon un exemple de réalisation, l'orifice d'aspiration 30 présente une forme étagée (figure 6) avec au moins un premier étage 30a ayant une première section d'aspiration et un deuxième étage 30b ayant une deuxième section d'aspiration plus petite que la première section d'aspiration. Le premier étage 30a débouche sur la face de la barre longitudinale 27a destinée à recevoir la feuille d'encart et le deuxième étage 30b débouche dans le canal d'aspiration 35 (figure 7).According to an exemplary embodiment, the suction orifice 30 has a stepped shape ( figure 6 ) with at least a first stage 30a having a first suction section and a second stage 30b having a second suction section smaller than the first suction section. The first stage 30a opens onto the face of the longitudinal bar 27a intended to receive the insert sheet and the second stage 30b opens into the suction channel 35 ( figure 7 ).

La plus grande section d'aspiration du premier étage 30a permet de répartir la force d'aspiration sous la surface de la feuille d'encart avec une grande surface de prise, ce qui est utile pour des feuilles particulièrement rigides. La plus petite section d'aspiration du deuxième étage 30a permet de saisir une feuille d'encart souple sans la déformer.The larger suction section of the first stage 30a makes it possible to distribute the suction force under the surface of the insert sheet with a large gripping surface, which is useful for particularly rigid sheets. The smaller suction section of the second stage 30a makes it possible to grasp a sheet of flexible insert without deforming it.

Par ailleurs, étant donné que le débit d'aspiration est limité à la petite section d'aspiration du deuxième étage 30b, on permet aux autres orifices d'aspiration 30 de fonctionner, même si un orifice d'aspiration 30 venait à ne pas être recouvert par la feuille d'encart.Furthermore, since the suction flow is limited to the small suction section of the second stage 30b, the other suction ports 30 are allowed to operate, even if a suction port 30 does not come to be covered by the insert sheet.

Les sections d'aspiration du premier et deuxième étage 30a, 30b présentent par exemple des formes circulaires concentriques. Un orifice bi-étagé formé par deux trous cylindriques de différents diamètres est particulièrement simple à réaliser et permet d'obtenir l'effet voulu avec une faible épaisseur, telle qu'une épaisseur de tôle, de l'ordre de 2mm.The suction sections of the first and second stages 30a, 30b have for example concentric circular shapes. A two-stage orifice formed by two cylindrical holes of different diameters is particularly simple to produce and makes it possible to obtain the desired effect with a small thickness, such as a sheet thickness, of the order of 2 mm.

Le rapport entre les sections d'aspiration est par exemple compris entre 2 et 50. Dans le cas de sections d'aspiration circulaires, le diamètre de la section d'aspiration du deuxième étage 30b peut être compris entre 3 et 9mm, tel que de l'ordre de 6mm et le diamètre de la section d'aspiration du premier étage 30a peut être compris entre 14 et 20mm, tel que de l'ordre de 17mm.The ratio between the suction sections is for example between 2 and 50. In the case of circular suction sections, the diameter of the suction section of the second stage 30b can be between 3 and 9mm, such as the order of 6mm and the diameter of the suction section of the first stage 30a can be between 14 and 20mm, such as of the order of 17mm.

Le dispositif de chargement 10 peut en outre comporter au moins un galet rotatif 33.The loading device 10 can also comprise at least one rotary roller 33.

Le galet rotatif 33 est sollicité élastiquement à l'encontre du chariot mobile 12 pour rouler sur la feuille d'encart lors du déplacement du chariot mobile 12 vers la zone de réception 2. Le galet rotatif 33 permet ainsi d'appuyer la feuille d'encart porté par le chariot mobile 12 contre les orifices d'aspiration 30 pour faciliter sa retenue, ce qui est particulièrement utile pour les feuilles d'encart épaisses et rigides, comme celles en carton.The rotary roller 33 is urged elastically against the movable carriage 12 to roll on the insert sheet when the movable carriage 12 moves towards the receiving zone 2. The rotary roller 33 thus makes it possible to support the sheet of insert carried by the movable carriage 12 against the suction orifices 30 to facilitate its retention, which is particularly useful for thick and rigid insert sheets, such as those made of cardboard.

Plus précisément, le galet rotatif 33 peut être configuré pour rouler sur la feuille d'encart le long d'une barre longitudinale 27a présentant au moins un orifice d'aspiration 30. On prévoit par exemple autant de galets rotatifs 33 que de barres longitudinales 27a présentant des orifices d'aspiration 30.More precisely, the rotary roller 33 can be configured to roll on the insert sheet along a longitudinal bar 27a having at least one suction orifice 30. For example, as many rotary rollers 33 are provided as there are longitudinal bars 27a having suction ports 30.

L'élément sur lequel est monté le galet rotatif 33 comporte par exemple une lame élastique 34 à une première extrémité de laquelle le galet rotatif 33 est monté. La deuxième extrémité de la lame élastique 34 est par exemple fixée au support 21 du dispositif de saisie 13 de feuilles d'encart pour que les galets rotatifs 33 soient situés au-dessus des barres longitudinales 27a et puissent venir exercer une pression sur la feuille d'encart.The element on which the rotary roller 33 is mounted comprises for example an elastic blade 34 at a first end of which the rotary roller 33 is mounted. The second end of the elastic blade 34 is for example fixed to the support 21 of the gripping device 13 for insert sheets so that the rotary rollers 33 are located above the longitudinal bars 27a and can come to exert pressure on the sheet d 'insert.

On va maintenant décrire le procédé de transport d'une feuille d'encart dans la zone de réception 2 en considérant comme position de départ la position sortie du chariot mobile 12 dans la zone de réception 2, à l'écart du bac 11 (figure 2). L'élément d'aspiration 20 est en position haute.We will now describe the method of transporting an insert sheet in the reception area 2 by considering as the starting position the out position of the mobile carriage 12 in the reception area 2, away from the tray 11 ( figure 2 ). The suction element 20 is in the high position.

L'élément d'aspiration 20 est déplacé en position basse pour saisir et soulever une feuille d'encart dans le logement 9 du bac 11. La feuille d'encart est ensuite lâchée sur le chariot mobile 12 de retour de la zone de réception 2 en position rentrée (figure 3) et recouvre les orifices d'aspiration 30.The suction element 20 is moved to the low position to grasp and lift an insert sheet in the housing 9 of the container 11. The insert sheet is then released on the mobile carriage 12 returning from the reception area 2 in the retracted position ( figure 3 ) and covers the suction ports 30.

L'unité de contrôle 7 pilote une basse pression d'aspiration dans les orifices d'aspiration 30 pour fixer la feuille d'encart au chariot mobile 12 et pilote le déplacement du chariot mobile 12 vers la zone de réception 2.The control unit 7 controls a low suction pressure in the suction orifices 30 to fix the insert sheet to the mobile carriage 12 and controls the movement of the mobile carriage 12 towards the reception zone 2.

Au départ du chariot mobile 12, les galets rotatifs 33 roulent sur la feuille d'encart le long des barres longitudinales 27, appuyant la feuille d'encart contre les orifices d'aspiration 30.At the start of the mobile carriage 12, the rotary rollers 33 roll on the insert sheet along the longitudinal bars 27, pressing the insert sheet against the suction orifices 30.

La feuille d'encart est ainsi maintenue en position pour son transport vers la zone de réception 2, malgré les accélérations et décélérations du chariot mobile 12.The insert sheet is thus held in position for its transport to the reception zone 2, despite the accelerations and decelerations of the mobile carriage 12.

A l'arrivée du chariot mobile 12 sous l'outil inférieur 3 de séparation des poses, l'unité de contrôle 7 arrête la basse pression d'aspiration dans les orifices d'aspiration 30. La feuille d'encart n'est alors plus retenue.When the mobile carriage 12 arrives under the lower tool for separating the blanks, the control unit 7 stops the low suction pressure in the suction ports 30. The insert sheet is then no longer detention.

De l'air peut être soufflé par le au moins un orifice d'aspiration 30 du chariot mobile 12 pour détacher plus facilement la feuille d'encart du chariot mobile 12 une fois le chariot mobile 12 arrivé dans la zone de réception 2 et la basse pression d'aspiration arrêtée.Air can be blown through the at least one suction port 30 of the mobile carriage 12 to more easily detach the insert sheet from the mobile carriage 12 once the mobile carriage 12 has arrived in the receiving zone 2 and the bottom suction pressure stopped.

Le chariot mobile 12 retourne ensuite au-dessus de la pile de feuilles d'encart recevoir une nouvelle feuille. En quittant la zone de réception 2, le chariot mobile 12 croise les dents du peigne de retenue 14 qui a pivoté en position de retenue (figure 2) pour retenir la feuille d'encart sur laquelle une nouvelle pile peut se déposer. La feuille d'encart ainsi bien positionnée sur le chariot mobile 12 peut donc être bien positionnée entre les poses de la pile.The movable carriage 12 then returns to the top of the stack of insert sheets to receive a new sheet. Leaving the reception area 2, the mobile carriage 12 crosses the teeth of the retaining comb 14 which has pivoted into the retaining position ( figure 2 ) to retain the insert sheet on which a new pile can be deposited. The insert sheet thus well positioned on the movable carriage 12 can therefore be well positioned between the poses of the stack.

Dans ce mode de réalisation, le chariot mobile 12 fait également office de grille de réception non-stop des poses. Il permet de soutenir les poses déposées sur la feuille d'encart pendant l'évacuation de la palette de réception 4 portant les piles complètes de poses hors de la station de réception et l'insertion d'une nouvelle palette de réception 4 vide, sans arrêt de la production.In this embodiment, the mobile carriage 12 also acts as a non-stop reception grid for the poses. It supports the poses deposited on the insert sheet during the evacuation of the receiving pallet 4 carrying the complete stacks of poses out of the receiving station and the insertion of a new empty receiving pallet 4, without production stopped.

Selon un autre mode de réalisation visible sur la figure 8, le chariot mobile 12' comporte un plateau 40 agencé sous les barres longitudinales 27a, 27b et fixé à ces dernières.According to another embodiment visible on the figure 8 , the movable carriage 12 ′ comprises a plate 40 arranged under the longitudinal bars 27a, 27b and fixed to the latter.

Les canaux d'aspiration 35 des barres longitudinales 27a peuvent être raccordés à un conduit ménagé dans le plateau 40 en remplacement de la traverse 26.The suction channels 35 of the longitudinal bars 27a can be connected to a duct formed in the plate 40 to replace the crosspiece 26.

Le chariot 12' est mobile entre une position rentrée pour recevoir une feuille d'encart et une position sortie pour la dépose de la feuille d'encart dans la zone de réception 2 entre les piles de poses. L'entrainement en translation du chariot mobile 12' peut être assuré par deux chaines 18 ou courroie(s) ou crémaillère(s) entrainées par un actionneur, tel qu'un vérin linéaire pneumatique (non visible), piloté par l'unité de contrôle 7 de la machine de traitement 1, pour programmer un encartage lorsque la pile de poses atteint la hauteur souhaitée.The carriage 12 'is movable between a retracted position for receiving an insert sheet and an extended position for depositing the insert sheet in the reception zone 2 between the stacks of poses. The moving carriage 12 'can be driven in translation by two chains 18 or belt (s) or rack (s) driven by an actuator, such as a pneumatic linear cylinder (not visible), controlled by the control 7 of the processing machine 1, to program an insert when the stack of poses reaches the desired height.

Toutefois, dans ce second mode de réalisation, le soutien des poses pendant l'évacuation des piles de poses sans arrêt de la production est réalisé par une grille de réception non-stop des poses 41 distincte, située en dessus du chariot mobile 12'.However, in this second embodiment, the support of the poses during the evacuation of the stacks of poses without stopping the production is carried out by a grid for receiving non-stop poses 41 separate, located above the movable carriage 12 '.

La grille de réception non-stop des poses 41 comporte une pluralité de barres longitudinales. Elle est mobile dans la direction longitudinale L entre une position rentrée dans laquelle elle est située au-dessus du dispositif de saisie 13 et une position sortie dans la zone de réception 2 de la station de réception des poses 500 pour recevoir les poses pendant l'évacuation de la palette de réception 4. La grille de réception non-stop des poses 41 est également mobile verticalement par entrainement motorisé pour s'adapter au niveau d'accumulation des poses sur le plateau 40. La grille de réception non-stop des poses 41 n'assure pas la fonction d'encartage.The non-stop reception grid for the poses 41 comprises a plurality of longitudinal bars. It is movable in the longitudinal direction L between a retracted position in which it is located above the gripping device 13 and an extended position in the reception zone 2 of the pose reception station 500 for receiving the poses during the evacuation of the receiving pallet 4. The non-stop reception grid for the poses 41 is also vertically movable by motorized drive to adapt to the level accumulation of the poses on the plate 40. The non-stop reception grid for the poses 41 does not provide the inserting function.

Il est également à noter que l'invention n'est pas limitée à une station de réception des poses 500 dans laquelle les points d'attache entre les poses sont séparés mais peut s'appliquer à une station de réception des poses réceptionnant des piles de feuilles pleines.It should also be noted that the invention is not limited to a pose reception station 500 in which the attachment points between the poses are separate but can be applied to a pose reception station receiving stacks of full sheets.
