Ainsi, la correction de polychromie s'effectuera en comparant une mire de référence avec une mire présente sur chaque support imprimé .Preferably, the collecting mat will transport each support at the end of the rack to the recipe with a reference of said support. According to a possibility offered by the invention, the system may include a color control device, for example an artificial vision camera, cooperating with the above rack in order to possibly correct the polychromy of the supports printed by the rack. Thus, the polychromy correction will be carried out by comparing a reference test pattern with a test pattern present on each printed support.
Grâce à ces particularités, l'invention propose un cheminement particulier des supports à imprimer dans le système d' impression, et plus précisément que chaque support soit introduit par le haut des modules pour être récupéré en bas. L'intérêt du système est ainsi double : profiter de la gravité pour gérer l'introduction de chaque support dans un module et son extraction et réaliser une impression alors que le support est sensiblement vertical, pour gagner de la place.Thanks to these features, the invention provides a particular path for the supports to be printed in the printing system, and more precisely that each support is introduced from the top of the modules to be recovered at the bottom. The advantage of the system is thus twofold: take advantage of gravity to manage the introduction of each support into a module and its extraction and make an impression while the support is substantially vertical, to save space.
On comprendra mieux l'invention à l'aide de la description, faite ci-après à titre purement explicatif, d'un mode de réalisation de l'invention, en référence aux figures annexées : la figure 1 illustre une vue partielle en coupe d'un système pour l'impression avec distribution à chaînes ; la figure 2 illustre une vue partielle en coupe d'un système pour l'impression avec distribution avec tapis.The invention will be better understood on the basis of the description, given below for purely explanatory purposes, of an embodiment of the invention, with reference to the appended figures: FIG. 1 illustrates a partial sectional view of '' a system for printing with chain distribution; Figure 2 illustrates a partial sectional view of a system for printing with distribution with carpet.
Le chargement du support peut s'effectuer de trois manières, non représentées sur les figures :The support can be loaded in three ways, not shown in the figures:
1 — manuellement, c'est-à-dire directement dans la marge 1, pour les petits formats ; 2 — à l'aide d'un transpalette directement accessible sur la plate- forme de marge 1, le support ayant été préparé, ou retaqué, sur un poste de préparation indépendant ; 3 — sur l'un des chariots à roulettes, par exemple de dimensions 55 x 70 cm, et ne pourront accueillir un support d'une taille maximum de 50 x 65 cm.1 - manually, that is to say directly in the margin 1, for small formats; 2 - using a pallet truck directly accessible on the margin platform 1, the support having been prepared, or reconditioned, on an independent preparation station; 3 - on one of the wheeled carts, for example of dimensions 55 x 70 cm, and cannot accommodate a support with a maximum size of 50 x 65 cm.
Une rampe de chargement doit être prévue. Cette rampe de faible inclinaison permet de monter sans difficulté des transpalettes ou des chariots pleins.A loading ramp must be provided. This low inclination ramp makes it easy to mount pallet trucks or full trolleys.
La capacité maximale est de 5000 supports de 350 g soit : un maximum de 1225 kg de support, le poids du plateau et de la palette étant à ajouter ; une hauteur maximale de support de 1100 mm.The maximum capacity is 5000 supports of 350 g, ie: a maximum of 1225 kg of support, the weight of the tray and the pallet being added; a maximum support height of 1100 mm.
Le transpalette est utilisé pour les grands formats (poids) . Le système selon l'invention s'utilise avec des chariots compatibles pour la marge 1 et la recette 7. Ils sont équipés de quatre roulettes orientables et verrouillables. Une poignée de manipulation doit être prévue sur le grand et le petit côté.The pallet truck is used for large formats (weight). The system according to the invention is used with compatible carriages for margin 1 and recipe 7. They are equipped with four adjustable and lockable casters. A handle for manipulation must be provided on the large and the small side.
Sur ces poignées, il est prévu un dispositif simple, crochetable ou encliquetable , permettant de manœuvrer le chariot en position debout, du type par exemple canne articulée.On these handles, there is provided a simple device, hookable or snap-on, making it possible to maneuver the trolley in a standing position, of the type for example articulated cane.
La marge 1 a deux fonctions principales : 1 — Le taquage de la tête de support le long de la grille d'équerrage et avant la prise de pince. Cette opération s'effectue au chargement du support de la marge 1. 2 — l'alimentation support à support des supports dans la machine.Margin 1 has two main functions: 1 - Jogging of the support head along the squaring grid and before gripping. This operation is performed when the margin 1 support is loaded. 2 - supply support to support of supports in the machine.
Dans le sens perpendiculaire au défilement, les supports sont centrés par rapport à l'axe machine (tolérance de positionnement par l'opérateur ±10 mm) . À cet effet, des repères des différents formats et centrage devront être prévus sur la plate- forme de marge 1 et chariots .In the direction perpendicular to the scrolling, the supports are centered relative to the machine axis (tolerance of positioning by the operator ± 10 mm). To this end, markers of the different formats and centering must be provided on the margin platform 1 and carriages.
La marge 1 est ici équipée d'une mise à niveau automatique en temps réel afin de maintenir le dessus du support toujours à la même altitude. La précision de positionnement est d'environ 2 mm. La montée et descente rapide de la plate- forme de marge 1 peuvent être accessible à l'opérateur en mode « mouvements manuels ».The margin 1 is here equipped with an automatic leveling in real time in order to maintain the top of the support always at the same altitude. The positioning accuracy is approximately 2 mm. The rapid raising and lowering of the margin platform 1 can be accessible to the operator in "manual movements" mode.
L'horizontalité du plateau est vérifiée à sensiblement 1 mm près.The horizontality of the plate is checked to within approximately 1 mm.
Les mouvements manuels du plateau seront les suivants : descente rapide du plateau jusqu'au seuil bas à la vitesse approximative de 50 mm/s, puis en phase d'approche à une vitesse plus faible permettant de limiter les chocs et attente à cette position, montée rapide du plateau jusqu'à ce que le haut de la palette arrive au niveau de la boîte et de la rampe de succion à la vitesse approximative de 100 mm/s, puis en phase d'approche à une vitesse plus faible et maintien du haut de la palette à ce niveau. Les mouvements manuels du plateau seront accessibles à la fin de l'impression et lors d'une interruption d'impression.The manual movements of the platform will be as follows: rapid descent of the platform to the low threshold at an approximate speed of 50 mm / s, then in the approach phase at a lower speed making it possible to limit shocks and waiting at this position, rapid rise of the platform until the top of the pallet reaches the level of the box and the suction ramp at an approximate speed of 100 mm / s, then in the approach phase at a lower speed and maintenance of the top of the palette at this level. The manual movements of the plate will be accessible at the end of printing and during a printing interruption.
Les equerres servent à guider le support vers la prise de pince.The brackets are used to guide the support towards the gripper socket.
Les equerres latérales sont réglables manuellement pour venir s'ajuster, éventuellement de manière automatique, aux différents formats. Elles sont rétractables ou relevables pour la fin de pile. Les equerres latérales ont ici une hauteur d' approximativement 15 cm. Elles se situent au niveau dessus de la pile et en arrière. L'altitude, ou la hauteur, des equerres est constante, soit 5 cm au-dessus de la pile et 10 cm au- dessous du niveau supérieur de la pile. Les equerres latérales sont en métal inoxydable.The side brackets are manually adjustable to adjust, possibly automatically, to the different formats. They are retractable or liftable for the end of the stack. The lateral brackets here have a height of approximately 15 cm. They are located above the stack and behind. The altitude, or height, of the brackets is constant, 5 cm above the pile and 10 cm below the upper level of the pile. The side brackets are made of stainless metal.
Un dispositif de soufflerie à débit réglable est prévu à l'arrière et à l'avant de la pile support au niveau haut ; le réglage pouvant être différent entre l'avant et l'arrière. Ce dispositif indépendant contribue encore à décoller les supports les uns des autres. Le dispositif prépare le passage des supports.A blower device with adjustable flow is provided at the rear and at the front of the support stack at the high level; the adjustment can be different between the front and the rear. This independent device also contributes to detaching the supports from each other. The device prepares the passage of the supports.
La boîte de succion commande l'envoi des supports vers les pinces. Elle est couplée à la rampe de succion située en tête de support. La boîte de succion peut s'ajuster pour tous les formats : avant/arrière : de 29,7 à 72 cm droite/gauche de 10 à 20 cm d'envergure.The suction box controls the sending of the supports to the clamps. It is coupled to the suction ramp located at the head of the support. The suction box can be adjusted for all formats: front / rear: from 29.7 to 72 cm right / left from 10 to 20 cm wingspan.
La boîte de succion est fixe lors de son travail ; une plate-forme située sous la boîte effectue un mouvement de va-et-vient, soit entre approximativement 8 et 10 cm. Cette plate-forme dispose de 3 sucettes disposées en triangle (2 à l'avant, 1 à l'arrière).The suction box is fixed during its work; a platform located under the box moves back and forth, between approximately 8 and 10 cm. This platform has 3 lollipops arranged in a triangle (2 at the front, 1 at the back).
Les deux sucettes (ventouses) situées à l'avant sont montées sur un système d'écartement réglable. À l'arrière de la boîte, un patin-souffleur descend sur le second support au moment où les sucettes soulèvent la première. Ce patin à trois actions :The two soothers (suction cups) located at the front are mounted on an adjustable spacing system. At the back of the box, a blower shoe descends on the second support when the pacifiers lift the first. This skate has three actions:
Il contribue à décoller les supports des unes des autres sur le haut de la pile, - Il souffle de l'air entre le 1er support et le deuxième support dans le tunnel créé,It helps to lift the supports from each other on the top of the pile, - It blows air between the 1st support and the second support in the tunnel created,
Il maintient le deuxième support sur la pile .It keeps the second support on the stack.
Un élément de réglage de débit d'air est également prévu dans le système. Les ventouses doivent avoir une aspiration suffisante pour décoller et maintenir un support d'un format 72 x 102 cm, présentant un poids d'environ 350 g/m2.An air flow control element is also provided in the system. The suction cups must have sufficient suction to take off and maintain a support of a format 72 x 102 cm, having a weight of approximately 350 g / m 2 .
La rampe de succion est située en tête de support, légèrement en arrière, soit environ à 8 - 10 cm. Elle est perpendiculaire au sens de passage du support. Sa fonction consiste à soulever le premier support de support sur le dessus de la pile, et à l'amener jusqu'à la prise de pinces, via un système d'accélération par roulettes. Elle dispose de 10 ventouses réparties sur un support et selon les différents formats de support. Suivant les formats utilisés, certaines ventouses, celles des extrémités, se trouvent dans le « vide ». Les ventouses peuvent se fermer et s'ouvrir pour s'adapter au format du support . Bien entendu, le va-et-vient de la rampe de succion est synchrone avec la boîte de succion et la prise de pince.The suction ramp is located at the head of the support, slightly behind, ie about 8 - 10 cm. It is perpendicular to the direction of passage of the support. Its function is to lift the first support support on top of the stack, and bring it to the gripper grip, via an acceleration system on casters. It has 10 suction cups distributed on a support and according to the different support formats. Depending on the formats used, some suction cups, those of the ends, are in the "vacuum". The suction cups can be closed and opened to adapt to the format of the support. Of course, the back and forth of the suction rail is synchronous with the suction box and the gripper socket.
Dans l'exemple choisi pour illustrer l'invention, Les pinces sont au nombre de dix sur chaque barre avec des intervalles prenant en compte les différents formats.In the example chosen to illustrate the invention, there are ten clamps on each bar with intervals taking into account the different formats.
Chaque pince doit avoir un serrage d'environEach clamp must have a clamping of approximately
350 g minimum. Les barres de pinces s'ouvrent et se ferment suivant la prise ou le lâcher du support. Les barres de pinces sont perpendiculaires aux chaînes. L'ensemble de barres de pinces est fixé sur les trains de chaîne disposés sur la partie haute et de chaque côté de la machine. Chaque rack 5 appelle un support, les pinces s'ouvrent par défaut au-dessus d'un rack 5 situé en bout de machine, ce réceptacle récupère ainsi les supports qui n'ont pas pu être distribués sur les supports ne reviennent pas à la marge 1.350 g minimum. The gripper bars open and close according to the grip or release of the support. The gripper bars are perpendicular to the chains. The set of gripper bars is fixed to the chain trains arranged on the upper part and on each side of the machine. Each rack 5 calls for a support, the clamps open by default above a rack 5 located at the end of the machine, this receptacle thus recovers the supports which could not be distributed on the supports do not return to the margin 1.
Les pinces sont montées par ensemble de 2 barres :The clamps are mounted in sets of 2 bars:
1 barre où sont fixées les pinces, - 1 barre de déclenchement d'ouverture et de fermeture des pinces . Cette barre dispose à son extrémité d'une came qui ouvre et ferme les pinces simultanément. Les pinces sont fermées par défaut.1 bar where the pliers are fixed, - 1 bar for opening and closing the pliers. This bar has at its end a cam which opens and closes the clamps simultaneously. The clamps are closed by default.
Chaque pince dispose d'un ressort de rappel.Each clamp has a return spring.
En cas de rupture de ce ressort, la pince restera libre pour ne pas entraver le fonctionnement de la machine. Les pinces sont aptes à s'ouvrir manuellement lors de l'arrêt ou de l'interruption de l'impression.In case of rupture of this spring, the clamp will remain free so as not to hamper the operation of the machine. The clamps are capable of opening manually when the printing is stopped or interrupted.
Dans l'exemple choisi pour illustrer l'invention, chaque barre de pinces est distante de la précédente d'environ 90 centimètres.In the example chosen to illustrate the invention, each gripper bar is spaced from the previous one by about 90 centimeters.
Le train de chaîne a une tension constante. Un tenseur assure la tension de la chaîne. Ce tenseur est prévu pour chaque chaîne de chaque côté de la machine. Ce dispositif se situe à l'extrémité et côté recette 7, ainsi l'allongement naturel de la chaîne est compensé.The chain train has constant tension. A tensioner ensures the chain tension. This tensor is provided for each chain on each side of the machine. This device is located at the end and on the recipe side 7, thus the natural lengthening of the chain is compensated.
Des guides sont disposés sur le brin tendu de la chaîne pour éviter les vibrations et contrer les réactions dues aux ouvertures de pince. L'avance et la vitesse de la chaîne sont synchrones avec la rampe de succion et la boîte de succion.Guides are arranged on the stretched strand of the chain to avoid vibrations and to counter reactions due to clamp openings. The feed and speed of the chain are synchronized with the suction boom and the suction box.
Le système de distribution 4 sera idéalement entièrement caréné. Ce carénage sera amovible afin de permettre l'extraction de supports coincés. L'ouverture de ce carénage entraîne un arrêt du système de distribution 4. La vitesse du système doit être au minimum de 0,7 m/s pour garantir l'approvisionnement de 20 racks 5. La distribution 4 et les systèmes synchrones seront mis au ralenti lors de l'impression, soit une mise en vitesse lente lorsque la distribution 4 n'a pas besoin de distribuer de supports. Ils seront arrêtés à la fin de chaque série. Des mouvements manuels avant et arrière seront disponibles pour pouvoir dégager un support lors d'une interruption d'impression. Le rack d'impression 5 est la partie située entre la marge 1 et la recette 7 ou entre la distribution 4 et le tapis collecteur 6.The distribution system 4 will ideally be completely streamlined. This fairing will be removable to allow the extraction of jammed supports. The opening of this fairing stops the distribution system 4. The system speed must be at least 0.7 m / s to guarantee the supply of 20 racks 5. The distribution 4 and the synchronous systems will be switched on. slowed down during printing, i.e. a slow speed up when distribution 4 does not need to distribute media. They will be stopped at the end of each series. Manual movements front and rear will be available to be able to release a support during a printing interruption. The printing rack 5 is the part located between the margin 1 and the recipe 7 or between the distribution 4 and the collecting mat 6.
Le rack d'impression 5 a plusieurs fonctions : 1 - Il reçoit le support prêt à être imprimé ;The printing rack 5 has several functions: 1 - It receives the support ready to be printed;
2 - Taque, ou rectifie, le support en tête ;2 - Taque, or rectify, the support at the head;
3 - Taque, ou rectifie, le support sur un côté, gauche ou droit ;3 - Taque, or rectify, the support on one side, left or right;
4 - Imprime le support ;4 - Print the support;
5 - Ejecte le support imprimé.5 - Ejects the printed support.
Le rack 5 est fermé sur le haut par un volet qui s'ouvre pour recevoir un support venant du système de distribution 4. L'ouverture et la fermeture du susdit doivent est très rapides, de plus il doit y avoir des lumières pour laisser passer les pinces. Le système d'ouverture doit être automatisé. La vitesse propre et l'inertie du support lui permettent de descendre dans le rack 5. Le support doit être pris en charge jusqu'au bas du rack 5.The rack 5 is closed at the top by a flap which opens to receive a support coming from the distribution system 4. The opening and closing of the above must be very rapid, in addition there must be lights to allow passage the clamps. The opening system must be automated. Its own speed and inertia allow it to descend into rack 5. The support must be supported to the bottom of rack 5.
Chaque support est éjecté sur le tapis collecteur 6 après l'impression. Une pression réglable sur des roulettes tient chaque support lors de certaines phases .Each support is ejected onto the collecting mat 6 after printing. An adjustable pressure on casters holds each support during certain phases.
Le moteur d' impression 2 est monté sur rail pour un changement ou une intervention rapide. LeThe print motor 2 is mounted on a rail for quick change or intervention. The
(re) positionnement de ce moteur à l'intérieur du rack 5 est d'une précision de 0,1 mm d'amplitude pour être en adéquation avec le système de rectification des tables de marge 1.(re) positioning of this motor inside the rack 5 is of an accuracy of 0.1 mm in amplitude to be in adequacy with the system of rectification of the margin tables 1.

Un tapis collecteur 6 transporte les supports en sortie de rack 5 vers la recette 7 avec une mise en référence du support.A collecting mat 6 transports the supports at the outlet of the rack 5 to the recipe 7 with a referencing of the support.
La vitesse du tapis 6 est comparable à celle de la distribution 4. Le tapis 6 sera mis en marche dès qu'un support sort d'un rack 5 et sera arrêté dès qu'il n'y a plus de support à transporter.The speed of the conveyor belt 6 is comparable to that of the distribution 4. The conveyor belt 6 will be started as soon as a support leaves a rack 5 and will be stopped as soon as there is no longer any support to be transported.
La recette 7 fonctionne de façon similaire à la marge 1. Elle reçoit les supports imprimés de tous les racks 5 par le biais du tapis collecteur 6.Recipe 7 works similarly to margin 1. It receives the printed media from all the racks 5 via the collecting mat 6.
La recette 7 doit être équipée d'une mise à niveau automatique en temps réel afin de maintenir le dessus du support toujours à la même altitude au fur et à mesure de l'empilage des supports. La précision de positionnement est d'environ 2 mm.Recipe 7 must be equipped with an automatic leveling in real time in order to maintain the top of the support always at the same altitude as the supports are stacked. The positioning accuracy is approximately 2 mm.
Un système de taquage, latéral et longitudinal, rectifie les supports au fur et à mesure de leur arrivée et de façon à les positionner centré par rapport à l'axe de la machine.A jogging system, lateral and longitudinal, corrects the supports as they arrive and so as to position them centered relative to the axis of the machine.
L'ajout d'une soufflerie au bout de la recette 7 peut être envisagé pour simplifier le retaquage. Le taquage de la tête du support repousse le support vers des grilles d'équerrage. La montée et descente rapide de la plate-forme de recette 7 doit être accessible à l'opérateur en mode « mouvements manuels ». Le déchargement de la recette 7 se fait de la même façon et par les mêmes moyens que le chargement de la marge 1.The addition of a blower at the end of recipe 7 can be envisaged to simplify the rework. Jogging the head of the holder pushes the holder towards squaring grids. The rapid ascent and descent of the recipe platform 7 must be accessible to the operator in "manual movements" mode. The unloading of the recipe 7 is done in the same way and by the same means as the loading of the margin 1.
En bout de recette 7, le système selon l'invention est équipé d'un dispositif de contrôle des couleurs utilisant une caméra de vision artificielle corrigeant la chromie des supports imprimés par le rack 5 d'impression. Ainsi, le support est identifié par un numéro de rack 5 imprimé et lit une mire multi-couleurs en faisant une comparaison avec une mire référence, la correction colorimétrique se fait par le biais de la carte couleur du moteur d'impression 2 du rack 5 analysé.At the end of recipe 7, the system according to the invention is equipped with a color control device using an artificial vision camera correcting the chromia of the supports printed by the printing rack 5. Thus, the support is identified by a rack number 5 printed and reads a multi-color test pattern by making a comparison with a reference test pattern, the colorimetric correction is done by means of the color card of the print engine 2 of the rack 5 analysis.
