D'UN GROUPE IMPRIMEUR, DESTINÉ À UNE MACHINE D'IMPRESSION,OF A PRINTER GROUP, FOR A PRINTING MACHINE,
ET DISPOSITIF DE TRANSPORT UTILISÉAND TRANSPORT DEVICE USED
La présente invention concerne un procédé de montage d'un groupe imprimeur pour une machine d'impression. L'invention concerne également un procédé de démontage d'un groupe imprimeur pour une machine d'impression. L'invention concerne également un procédé de transformation d'un groupe imprimeur pour une machine d'impression. L'invention concerne un dispositif de transport utilisable dans un procédé de montage, de démontage et/ou de transformation d'un groupe imprimeur, destiné à une machine d'impression. La présente invention se rapporte également à un dispositif destiné à être utilisé en étant entré dans un groupe imprimeur destiné à une machine d'impression. Le groupe imprimeur est plus spécifiquement utilisé dans une machine d'impression en héliogravure.The present invention relates to a method of mounting a printing unit for a printing machine. The invention also relates to a method of disassembling a printing unit for a printing machine. The invention also relates to a method of converting a printing unit for a printing machine. The invention relates to a transport device that can be used in a method for mounting, dismantling and / or transforming a printing unit, intended for a printing machine. The present invention also relates to a device for use in entering a printing unit for a printing machine. The printing group is more specifically used in a gravure printing machine.
L'héliogravure, également appelée hélio est un procédé d'impression rotatif utilisable pour de nombreux supports, dont le papier ou le carton, utilisant des cylindres gravés. L'impression en hélio est employée particulièrement pour les éditions de grande qualité et de grands tirages où le graphisme doit jouer un rôle important pour assurer la promotion d'un produit, tel qu'un emballage sous la forme d'une boîte en carton. Ce procédé d'impression permet en un seul passage d'imprimer jusqu'à douze couleurs, voire plus, avec des encres à solvants.Photogravure, also called rotogravure, is a rotary printing process that can be used for many substrates, including paper or cardboard, using engraved cylinders. Gravure printing is used especially for high-quality editions and large prints where graphics must play an important role in promoting a product, such as a carton pack. In one pass, this printing process can print up to twelve or more colors with solvent inks.
Ainsi, dans une machine d'impression en hélio, un support à imprimer sous la forme d'une bande continue traverse une succession de groupes imprimeurs hélio. Les groupes imprimeurs sont assemblés et disposés longitudinalement les uns à la suite des autres depuis l'entrée du support à imprimer en amont jusqu'à sa sortie en aval. Chaque groupe imprimeur procède à l'impression d'un motif avec une seule couleur spécifique ou un vernis particulier, ou bien encore effectue un gaufrage. De plus en plus d'utilisateurs veulent posséder une machine d'impression présentant une grande souplesse d'utilisation. Ainsi, tout d'abord, ils souhaitent effectuer des changements extrêmement rapides de travail par modification des cylindres d'impression gravés, afin de faire face aux demandes de plus en plus ponctuelles d'impression en petites séries de leurs clients. Ensuite, le besoin s'est fait sentir en terme d'effets visuels supplémentaires devant être reproduits sur le support, tels que dorures et argentures, vernis mats, brillants ou structurés, recto, verso, gaufrages, et d'autres encore, nécessitant par là même de nouvelles techniques d'impression. Cependant, en raison de la longueur des machines d'impression et en raison des coûts très élevés, ils peuvent rarement rajouter des groupes d'impression supplémentaires en milieu de machine d'impression.Thus, in a gravure printing machine, a medium to be printed in the form of a continuous strip passes through a succession of gravure printing units. The printing units are assembled and arranged longitudinally one after the other from the input of the print medium upstream to its output downstream. Each printing group proceeds to print a pattern with a single specific color or a particular varnish, or else performs an embossing. More and more users want to have a printing machine with great flexibility. So, first of all, they want to make extremely fast changes of work by modifying engraved print cylinders, in order to cope with the demands of more and more punctual printing in small series of their customers. Then, the need was felt in terms of additional visual effects to be reproduced on the support, such as gilding and silvering, matte, glossy or structured varnishes, front, back, embossing, and others, requiring by there even new printing techniques. However, because of the length of the printing machines and because of the very high costs, they can rarely add additional printing units in the middle of the printing machine.
Etat de la technique Pour faciliter cette adaptabilité des groupes imprimeurs, le documentState of the art To facilitate this adaptability of printing groups, the document
US- 3.625.145 décrit un chariot imprimeur amovible destiné à être utilisé en impression hélio, afin de faciliter une manutention et une permutation des cylindres gravés. Le chariot comprend un châssis, des moyens coopérant avec les moyens de support du groupe imprimeur, un cylindre d'impression gravé tournant par rapport au chariot. Ce chariot s'insère dans un volume situé à l'intérieur d'un groupe imprimeur, qui intègre des moyens de support pour le recevoir. Le cylindre d'impression est verrouillé à un mécanisme d'entraînement.US-3,625,145 discloses a removable printing carriage for use in gravure printing, to facilitate handling and permutation of the engraved rolls. The carriage comprises a frame, means cooperating with the support means of the printing unit, an engraved impression cylinder rotating relative to the carriage. This carriage fits into a volume located inside a printing unit, which integrates support means to receive it. The impression cylinder is locked to a drive mechanism.
Cependant, un tel chariot n'est utilisé spécifiquement que pour les cylindres gravés. De plus, le système de racle reste monté à demeure sur le chariot et ne peut être enlevé de manière aisée.However, such a trolley is only used specifically for engraved cylinders. In addition, the squeegee system remains permanently mounted on the carriage and can not be removed easily.
On connaît d'après le document FR- 2.563.469 un groupe imprimeur hélio muni de deux systèmes de racle disposés longitudinalement et sur deux côtés opposés, par rapport au cylindre, de façon à permettre au besoin une impression recto ou une impression verso. Un chariot est utilisé pour faciliter l'introduction et l'extraction du cylindre dans le groupe imprimeur, selon une direction longitudinale par rapport au groupe imprimeur. L'un des systèmes de racle est relié à une pièce de structure du groupe imprimeur. La pièce de structure coulisse à la verticale le long de glissières entre une position inférieure, dans laquelle le système de racle est en position d'utilisation, et une position supérieure dans laquelle ce même système de racle se trouve à une hauteur plus élevée au-dessus du cylindre.Document FR-2.563.469 discloses a gravure printing unit provided with two squeegee systems arranged longitudinally and on two opposite sides, with respect to the cylinder, so as to allow, if necessary, a front printing or a back printing. A carriage is used to facilitate the introduction and extraction of the cylinder in the printing unit, in a longitudinal direction relative to the printing unit. One of the squeegee systems is connected to a structural part of the printing unit. The structural member slides vertically along slideways between a lower position, in which the doctor blade is in the use position, and an upper position in which the same doctor system is at a higher elevation than above the cylinder.
Cependant, un tel groupe imprimeur exige la présence à demeure de deux systèmes de racle, l'un des deux restant inutilisé lorsque l'autre fonctionne. Un système de racle surnuméraire rend le groupe imprimeur coûteux. De plus, rien n'est prévu pour enlever le ou les systèmes de racle, pour des interventions sur le groupe imprimeur ou pour d'autres modifications de ce même groupe imprimeur.However, such a printing unit requires the permanent presence of two squeegee systems, one of the two remaining unused when the other operates. A supernumerary squeegee system makes the printer group expensive. In addition, nothing is planned for remove the squeegee system (s), for interventions on the printer group or for other modifications of the same printer group.
Le document EP- 0.682.601 divulgue un chariot qui est destiné à être utilisé dans différents types de machines à imprimer. Ce chariot porte une ou plusieurs parties amovibles, ce qui permet de les insérer et de les retirer du groupe imprimeur de la machine à imprimer. Un système de racle, ici sous la forme d'une chambre à racle, fait partie des parties amovibles. Le chariot est positionné longitudinalement par rapport au groupe imprimeur. Le chariot comprend un châssis mobile amenant ou retirant la ou les parties amovibles. Des moyens de transfert et des moyens de fixation de la ou des parties amovibles à l'intérieur du groupe imprimeur sont également prévus.EP-0.682.601 discloses a carriage which is intended to be used in different types of printing machines. This carriage carries one or more removable parts, which allows them to be inserted and removed from the printer unit of the printing machine. A doctor blade system, here in the form of a doctor blade chamber, is part of the removable parts. The carriage is positioned longitudinally with respect to the printer unit. The carriage comprises a movable frame bringing or removing the removable part or parts. Transfer means and means for fixing the removable part or parts inside the printing unit are also provided.
Cependant, un tel chariot reste spécifiquement dédié à ce groupe imprimeur, dont l'introduction des parties amovibles doit impérativement se faire longitudinalement et dans un seul sens. Rien n'est prévu pour positionner le système de racle pour une impression verso. De plus, le but du chariot n'est que de faciliter l'introduction et la sortie des parties amovibles pour des interventions de nettoyage et de réparation. Les éléments d'accouplement internes pour les parties amovibles restent fixés à demeure au groupe imprimeur.However, such a carriage remains specifically dedicated to this printing group, the introduction of removable parts must imperatively be done longitudinally and in one direction. Nothing is planned to position the squeegee system for back printing. In addition, the purpose of the carriage is only to facilitate the introduction and exit of the removable parts for cleaning and repair operations. The internal coupling elements for the removable parts remain permanently attached to the printing unit.

Autrement dit, en prévoyant un dispositif de transport spécifique au système de racle, ce dernier peut être facilement déplacé, pour permettre à l'opérateur de monter le groupe imprimeur en fonction de ses besoins. Le dispositif de transport est défini comme étant un ensemble, pouvant être déplacé, pouvant supporter le poids du système de racle, et muni ou non de roues, de type chariot de transport ou d'autres encore. Le dispositif de transport est dimensionné de manière adéquate, pour son entrée à l'intérieur et sa sortie à l'extérieur du bâti du groupe imprimeur, en étant manœuvrable par un opérateur.In other words, by providing a transport device specific to the squeegee system, the latter can be easily moved to allow the operator to mount the printing unit according to his needs. The transport device is defined as a movable assembly capable of supporting the weight of the doctor blade system, with or without wheels, transport cart type or the like. The transport device is suitably dimensioned, for its entry inside and its exit outside the frame of the printing unit, being operable by an operator.
Conformément à un autre aspect, la présente invention vise un procédé de démontage et/ou de transformation d'un groupe imprimeur appartenant à une machine d'impression, le groupe imprimeur comprenant un bâti, un chariot imprimeur, entré à l'intérieur et solidarisé au bâti, et un système de racle, indépendant du chariot imprimeur et solidarisé à ce bâti.According to another aspect, the present invention aims at a method of disassembly and / or transformation of a printing unit belonging to a printing machine, the printing unit comprising a frame, a printer carriage, entered inside and joined together. to the frame, and a squeegee system, independent of the printer carriage and secured to this frame.
Le procédé de démontage et/ou de transformation est caractérisé en ce qu'il comprend les étapes consistant à :The disassembly and / or transformation method is characterized in that it comprises the steps of:
- désolidariser ce chariot imprimeur de ce bâti,- to separate this printer carriage from this frame,

En d'autres termes, avec le système de racle amovible, l'accès de l'opérateur aux autres organes du groupe imprimeur est facilité. En enlevant, le système de racle, l'opérateur dégage de la place à l'intérieur du groupe imprimeur, ce qui permet de modifier plus aisément ce même groupe imprimeur. De plus, avec le dispositif de transport et le chariot imprimeur, toute modification du groupe imprimeur reste très facile à effectuer par l'opérateur.- Remove this transport device with this squeegee system outside of this frame. In other words, with the removable squeegee system, the access of the operator to the other organs of the printing unit is facilitated. By removing the squeegee system, the operator clears space inside the printing unit, which makes it easier to modify the same printing unit. In addition, with the transport device and the printer carriage, any modification of the printing unit remains very easy to carry out by the operator.
L'invention concerne également un dispositif de transport, apte à transporter un système de racle, à entrer à l'intérieur et à sortir à l'extérieur d'un bâti d'un groupe imprimeur appartenant à une machine d'impression, comprenant un châssis et un élément porteur, caractérisé en ce qu'il présente une capacité à entrer et à sortir transversalement par rapport au bâti, et en ce que l'élément porteur présente une capacité à être mobile selon une direction sensiblement longitudinale, pour prendre deux positions extrêmes dans des sens amont et aval, de façon à permettre une solidarisation ou une désolidarisation, et un transport du système de racle. Dans toute la description, la direction longitudinale est définie comme étant la direction horizontale de progression du support à imprimer tout au long de la machine d'impression. Le sens amont est défini comme étant le sens horizontal à partir duquel le support à imprimer vierge entre dans le groupe imprimeur ou dans la machine d'impression. Le sens aval est défini comme étant le sens horizontal vers lequel le support imprimé graphiquement sort du groupe imprimeur ou de la machine d'impression. La direction transversale est définie comme étant la direction horizontale perpendiculaire à la direction de progression du support à imprimer.The invention also relates to a transport device, able to transport a squeegee system, to enter inside and to exit outside a frame of a printing unit belonging to a printing machine, comprising a frame and a carrier element, characterized in that it has a capacity to enter and exit transversely relative to the frame, and in that the carrier element has a capacity to be movable in a substantially longitudinal direction, to take two positions extremes in upstream and downstream directions, so as to allow a connection or a separation, and a transport of the doctor blade system. Throughout the description, the longitudinal direction is defined as the horizontal direction of progression of the medium to be printed throughout the printing machine. The upstream direction is defined as the horizontal direction from which the blank print media enters the printer group or the printing machine. The downstream direction is defined as the horizontal direction towards which the graphically printed medium exits the printing unit or the printing machine. The transverse direction is defined as the horizontal direction perpendicular to the direction of progression of the medium to be printed.
Autrement dit, le dispositif permet non seulement l'entrée, la sortie et le transport du système de racle, mais également un positionnement inversé du système de racle dans le groupe imprimeur. La position en aval autorise l'impression côté recto et la position en amont autorise l'impression côté verso.In other words, the device not only allows the entry, exit and transport of the doctor blade system, but also an inverted positioning of the doctor blade system in the printing unit. The downstream position allows front-side printing and the upstream position allows for back side printing.

Exposé détaillé de modes de réalisation préférés Comme l'illustre la Figure 1, une machine d'impression est composée de plusieurs groupes imprimeurs (1, 2, 3 et 4) qui sont montés successivement les uns à la suite des autres afin de constituer une machine d'impression. Un support à imprimer (6) rentre en amont (Flèche I en Figure 1) dans chacun des groupes imprimeurs (1, 2, 3 et 4), par exemple pour être imprimé avec une couleur, en ressort en aval (Flèche O). Le support à imprimer (6) entre (I) et ressort (O) dans autant de groupes imprimeurs (1, 2, 3 et 4) que nécessaires, pour réaliser les impressions de couleurs différentes ou les effets nécessaires.DETAILED DISCUSSION OF PREFERRED EMBODIMENTS As illustrated in FIG. 1, a printing machine is composed of several printing units (1, 2, 3 and 4) which are successively mounted one after the other in order to constitute a printing machine. A print medium (6) goes upstream (Arrow I in Figure 1) in each of the printer groups (1, 2, 3 and 4), for example to be printed with a color, spring downstream (Arrow O). The print media (6) between (I) and spring (O) in as many printer groups (1, 2, 3 and 4) as necessary, to make the different color prints or the necessary effects.
Chaque groupe imprimeur (1, 2, 3 et 4) comprend un chariot imprimeur (7), présentant lui-même un cylindre gravé (8), une arrivée d'encre qui amène l'encre sur le cylindre gravé (8), un bac à encre, qui récupère le trop plein d'encre. Chaque groupe imprimeur (1, 2, 3 et 4) possède également un bâti (9), un sécheur (11), qui assure l'évaporation rapide des solvants ou de l'eau, ou bien la polymérisation des encres à UV, un rouleau presseur (12), qui appuie fortement le support à imprimer (6) sur le cylindre (8), et une pompe qui assure l'alimentation en encre du réservoir à l'applicateur d'encre (non représentée en Figure 1). Le chariot imprimeur (7) est entré ou inséré dans un volume vide (13) ménagé au centre du bâti (9), en étant rentré transversalement, c'est-à-dire perpendiculairement au sens de progression du support (6). Un système de racle (14) élimine le surplus d'encre sur le cylindre (8) au moyen d'une lame de raclage, arasant la surface périphérique du cylindre (8) et ne laissant que l'encre qui a pénétré dans les alvéoles. Le système de racle (14) est fixé au bâti (9). Le système de racle (14) fait saillie dans le volume (13) du bâti (9).Each printing unit (1, 2, 3 and 4) comprises a printer carriage (7), itself having an engraved cylinder (8), an ink supply which brings the ink onto the engraved cylinder (8), a ink tray, which recovers the overflow of ink. Each printing unit (1, 2, 3 and 4) also has a frame (9), a dryer (11), which ensures the rapid evaporation of solvents or water, or the polymerization of UV inks, a pressure roller (12), which strongly presses the print medium (6) on the cylinder (8), and a pump that supplies the reservoir ink to the ink applicator (not shown in FIG. 1). The printing carriage (7) is inserted or inserted into an empty volume (13) formed in the center of the frame (9), being retracted transversely, that is to say perpendicularly to the direction of progression of the support (6). A squeegee system (14) removes excess ink on the cylinder (8) by means of a scraper blade, smoothing the peripheral surface of the cylinder (8) and leaving only ink that has penetrated into the cells . The squeegee system (14) is fixed to the frame (9). The squeegee system (14) protrudes into the volume (13) of the frame (9).
Le premier groupe imprimeur (1) réalise une impression recto et le deuxième groupe imprimeur (2) réalise une impression verso du support à imprimer (6), ce qui demande un positionnement inversé du système de racle (14), côté aval ou côté amont, par rapport au sens d'avancement (I et O) du support à imprimer (6), et un mécanisme de cheminement différent du support à imprimer (6) à l'intérieur du bâti (9).The first printing unit (1) performs a single-sided printing and the second printing unit (2) performs a back printing of the print medium (6), which requires an inverted positioning of the squeegee system (14), downstream side or upstream side , relative to the direction of advance (I and O) of the medium to be printed (6), and a tracking mechanism different from the medium to be printed (6) inside the frame (9).
Comme le représente la Figure 1, pour passer d'un bâti vide (9) par exemple à un groupe imprimeur recto (1) ou à un groupe imprimeur verso (2), et selon l'invention, un procédé de montage d'un groupe imprimeur comprend plusieurs étapes. Une première étape consiste à poser le système de racle (14) sur un dispositif de transport ou chariot de transport vide (16), à l'extérieur du bâti (9). Une deuxième étape consiste à faire entrer ou insérer le chariot de transport (16) avec le système de racle (14) dans le bâti (9) du groupe imprimeur (1 et 2).As shown in FIG. 1, to pass from an empty frame (9) for example to a front printing unit (1) or to a back printing unit (2), and according to the invention, a method of mounting a Printer group includes several steps.

Conformément à l'invention, l'élément porteur (22) est mobile selon une direction sensiblement longitudinale, pour prendre deux positions extrêmes dans des sens amont et aval par rapport au sens de progression du support à imprimer (6), de façon à permettre une solidarisation ou une désolidarisation du système de racle (14).According to the invention, the carrier element (22) is movable in a substantially longitudinal direction, to take two extreme positions in upstream and downstream directions with respect to the direction of progression of the printing medium (6), so as to allow a joining or disconnection of the doctor blade system (14).
Lorsque l'élément porteur (22) se trouve en position extrême dans le sens aval (voir Figure 5), le système de racle (14) est solidarisé au groupe imprimeur (1) pour que ce dernier fasse une impression recto. Lorsque l'élément porteur (22) se trouve en position extrême dans le sens amont (voir Figure 6), le système de racle (14) est solidarisé au groupe imprimeur (2), pour que ce dernier fasse une impression verso.When the carrier member (22) is in the extreme position in the downstream direction (see Figure 5), the squeegee system (14) is secured to the printing unit (1) for the latter to perform a simplex printing. When the carrier member (22) is in the extreme position in the upstream direction (see Figure 6), the doctor blade system (14) is secured to the printing unit (2), so that the latter makes a back printing.
Pour permettre le déplacement du système de racle (14) vers ou à partir des deux positions extrêmes, l'élément porteur (22) comprend deux barres longitudinales (24) reliées par une entretoise transversale (26). Le système de racle (14) repose sur les deux barres longitudinales (24). Les deux barres longitudinales (24) sont mobiles en coulissant dans deux rails longitudinaux (27), attachés aux deux poutres supérieures (23). Le coulissement se fait dans le sens amont (Flèches SU en Figure 5) et dans le sens aval (Flèches SD en Figure 6). Le coulissement est réalisé par engrènement de deux crémaillères longitudinalesTo allow movement of the doctor blade system (14) to or from the two extreme positions, the carrier member (22) comprises two longitudinal bars (24) connected by a transverse spacer (26). The squeegee system (14) rests on the two longitudinal bars (24). The two longitudinal bars (24) are slidably movable in two longitudinal rails (27), attached to the two upper beams (23). The sliding is done in the upstream direction (arrows SU in Figure 5) and in the downstream direction (arrows SD in Figure 6). Sliding is achieved by meshing two longitudinal racks
(28), fixées aux deux barres longitudinales (24), avec deux pignons longitudinaux (29). Les deux pignons (29) sont reliés entre eux par une tringle (31) et entraînés grâce à un volant (32) et une poignée (33). Lorsque l'opérateur tourne le volant (32), la tringle (31) et les pignons (29) tournent, ce qui entraîne le déplacement de la crémaillère (29) et des deux barres longitudinales (24). L'opérateur vient ainsi, soit chercher le système de racle (14), pour le démontage et la transformation du groupe imprimeur (1 et 2), soit placer le système de racle (14), en position recto ou verso, pour le montage du groupe imprimeur (1 et 2).(28), fixed to the two longitudinal bars (24), with two longitudinal gears (29). The two gears (29) are interconnected by a rod (31) and driven by a steering wheel (32) and a handle (33). When the operator turns the steering wheel (32), the rod (31) and the pinions (29) rotate, which causes the movement of the rack (29) and the two longitudinal bars (24). The operator thus comes either to look for the squeegee system (14), for the disassembly and transformation of the printing unit (1 and 2), or to place the squeegee system (14), in front or back position, for mounting of the printing group (1 and 2).
Comme cela est visible en Figure 7, le chariot de transport (16) peut comprendre des moyens de centrage, aptes à coopérer avec des moyens de centrage, conjugués, correspondants et présents dans le bâti du groupe imprimeur.
