Description

L'invention concerne les rotatives d'impression sur un support mince dévidé en continu à partir d'une bobine.The invention relates to printing presses on a thin support unwound continuously from a spool.

Le procédé d'impression sur rotative est bien connu pour obtenir sur un support défilant en continu, la reproduction de dessins et de signes graphiques quelconques gravés sur une forme cylindrique, ou encore pour réaliser des enductions en aplats. Les formes peuvent être gravées en creux (héliographie) ou en relief (typographie, flexographie) et l'impression ou l'enduction réalisée à l'aide de produits divers appropriés au résultat recherché : encres d'imprimerie, carbones, self-adhésifs, colles thermofusibles, enductions chimiques pour papiers autoreproducteurs ou pour papiers dits "chimiques", etc. Le produit est transféré sur le support à partir d'un bac dans lequel barbote un cylindre tournant qui peut être directement un cylindre gravé en creux (héliographie) ou un cylindre preneur enduisant les formes en relief portées par un cylindre porte-clichés par l'intermédiaire d'un cylindre toucheur (typographie, flexographie). Le produit restant dans les creux de la gravure, après essuyage du cylindre gravé à l'aide d' une râcle prenant appui le long d'une de ses génératrices (héliographie), ou enduisant les reliefs des clichés (typographie,flexographie); est déposé sur le support qui, à la fin du processus, est mis en contact intime avec le cylindre gravé ou le cylindre porte-clichés, par un rouleau presseur revêtu de caoutchouc et soumis à une pression de nature hydraulique ou mécanique.The rotary printing process is well known for obtaining, on a continuously moving support, the reproduction of any drawings and graphic signs engraved on a cylindrical shape, or else for making solid coatings. The shapes can be engraved intaglio (heliography) or embossed (typography, flexography) and printing or coating carried out using various products appropriate to the desired result: printing inks, carbons, self-adhesives, hot-melt adhesives, chemical coatings for self-reproducing papers or for so-called "chemical" papers, etc. The product is transferred to the support from a tank in which a rotating cylinder is bubbled which can be directly a hollow engraved cylinder (heliography) or a taker cylinder coating the relief shapes carried by a plate cylinder intermediate of a touch cylinder (typography, flexography). The product remaining in the hollow of the engraving, after wiping of the engraved cylinder using a doctor blade taking support along one of its generatrices (heliography), or coating the reliefs of the stereotypes (typography, flexography); is deposited on the support which, at the end of the process, is brought into intimate contact with the engraved cylinder or the plate-holding cylinder, by a pressure roller coated with rubber and subjected to a pressure of hydraulic or mechanical nature.

Pour que le produit présente des caractéristiques physiques et/ou chimiques satisfaisantes, il est fréquent qu'il faille déterminer et imposer une température assez précise au moment du dépôt sur le support. C'est le cas notamment pour les carbones, les colles thermofusibles et les enductions émettrices et réceptrices des papiers chimiques. La viscosité à froid du produit peut, en outre, nécessiter un chauffage pendant le stockage dans le bac et pendant tout le processus de transfert (cas notamment des colles thermofusibles).For the product to have satisfactory physical and / or chemical characteristics, it is frequent that it is necessary to determine and impose a fairly precise temperature at the time of deposition on the support. This is particularly the case for carbons, hot-melt adhesives and emitting and receiving coatings for chemical papers. The cold viscosity of the product may also require heating during storage in the tank and during the entire transfer process (in particular the case of hot-melt adhesives).

Dans tous les cas, des variations trop rapides de la température du produit au cours du transfert, c'est-à-dire au cours de la période où il est déjà soumis à des pressions par écrasement variables, peuvent entraîner des modifications irréversibles des propriétés du produit considéré.In all cases, too rapid variations in the temperature of the product during transfer, that is to say during the period when it is already subjected to variable crushing pressures, may cause irreversible changes in the properties of the product under consideration.

On a alors imaginé de "mettre en température" le bac de stockage, la forme cylindrique,le rouleau presseur et chacun des organes complémentaires de la rotative (râcles d'essuyage ou autre pour l'héliogravure - cylindre preneur et cylindre toucheur pour la typographie ou la flexographie) en les chauffant indépendamment les uns des autres, à l'aide de bains d'huile et de cannes chauffantes, avec régulation ther- mostatique. Cette solution est peu satisfaisante d'une part à cause de la consommation d'énergie (grosse perte de calories dans l'air ambiant) et d'autre part parce que l'on ne supprime pas totalement les variations de température, la dispersion et la conduction de chaleur variant d'un organe à l'autre.We then imagined to "warm up" the storage tank, the cylindrical shape, the pressure roller and each of the complementary organs of the press (wiping or other scrapers for gravure printing - take-up cylinder and touch cylinder for typography or flexography) by heating them independently of each other, using oil baths and heating rods, with thermostatic regulation. This solution is unsatisfactory on the one hand because of the energy consumption (large loss of calories in the ambient air) and on the other hand because the temperature variations, the dispersion and heat conduction varying from one organ to another.

L'invention prévoit une structure qui assure une parfaire égalité entre les températures dans le bac, à la surface de chaque organe actif y compris la zone de contact du rouleau presseur et sur la surface du support qui se présente en position d'impression. Ce dernier point est très important pour assurer l'homogénéité du dépôt sur toute son épaisseur.The invention provides a structure which ensures perfect equality between the temperatures in the tank, on the surface of each active member including the contact area of the pressure roller and on the surface of the support which is in the printing position. This last point is very important to ensure the uniformity of the deposit over its entire thickness.

Selon l'invention, la rotative comporte une enceinte qui renferme le bac, la forme gravée et les organes complémentaires et qui est constituée en deux parties séparables réunies de façon sensiblement étanche, à savoir une partie fixe solidaire du bâti de la rotative et qui reçoit les moyens d'alimentation, de contrôle de niveau et de circulation du produit ainsi que les moyens de réglage en hauteur du bac et une partie mobile qui porte des paliers dans lesquels tourillonnent la forme gravée et les organes complémentaires, tandis qu'une fenêtre ménagée sur la face supérieure de l'enceinte permet le passage de la partie inférieure du rouleau presseur et qu'au moins une arrivée d'air pulsé à température contrôlée est prévue à la partie basse de la partie fixe de 1' enceinte.According to the invention, the press comprises an enclosure which contains the tray, the engraved shape and the complementary members and which is made up of two separable parts joined in a substantially sealed manner, namely a fixed part integral with the frame of the press and which receives the means for supplying, leveling and circulating the product as well as the means for adjusting the height of the tank and a movable part which carries bearings in which the engraved shape and the complementary members revolve, while a window is provided on the upper face of the enclosure allows the passage of the lower part of the pressure roller and that at least one supply of forced air at controlled temperature is provided at the lower part of the fixed part of one enclosure.

Ainsi, tous les organes actifs sont dans le même courant d'air à température contrôlée et sont ainsi maintenus tous à la même température, y compris le cylindre presseur et la partie du support en position d'impression qui sont placés dans la fenêtre et qui sont donc léchés par le courant d'air s'échappant vers l'extérieur.Thus, all the active members are in the same air stream at controlled temperature and are thus all kept at the same temperature, including the pressure cylinder and the part of the support in the printing position which are placed in the window and which are therefore licked by the air flow escaping to the outside.

On comprend qu'ainsi il est possible de réaliser l'impression ou l'enduction à une température précise prédéterminée même assez élevée (jusqu'à 150°C et plus). Mais l'enceinte présente également des avantages importants pour l'enduction à froid, par exemple pour les enductions de self-adhésifs, utilisant pour le produit un solvant volatil, car le volume restreint de l'enceinte permet d'être rapidement en atmosphère saturée, ce qui assure la stabilité du produit.It is understood that in this way it is possible to carry out printing or coating at a precise predetermined temperature, even quite high (up to 150 ° C. and more). However, the enclosure also has significant advantages for cold coating, for example for self-adhesive coatings, using a volatile solvent for the product, since the limited volume of the enclosure makes it possible to be quickly in a saturated atmosphere. , which ensures the stability of the product.

L'enceinte assure encore une protection contre les blessures par contact involontaire en cours de fonctionnement. Elle réduit considérablement les émissions d'odeurs (à froid ou à chaud) provenant de 11 évaporation de certains composants du produit.The enclosure still provides protection against injury from unintentional contact during operation. It considerably reduces odor emissions (cold or hot) from 1 1 evaporation of certain product components.

L'invention sera mieux comprise à la lecture de la description qui va suivre et à l'examen du dessin annexé, dont la figure unique représente, à titre d'exemple non limitatif, une presse héliographique munie des perfectionnements selon l'invention. Sur cette figure la presse est représentée avec les deux parties de l'enceinte séparées et avec des coupes et des arrachements partiels. Pour plus de clarté certains éléments ne faisant pas partie de l'invention ne sont pas représentée, tels que l'axe de pivotement de la râcle 14, les moyens de levage et de réglage du bac 13, l'organe d'entraînement du cylindre gravé 12 calé sur l'arbre 26, les moyens d'alimentation, de contrôle de niveau et de circulation du produit, etc.The invention will be better understood on reading the description which follows and on examining the appended drawing, the single figure of which represents, by way of nonlimiting example, a heliographic press provided with improvements according to the invention. In this figure, the press is shown with the two parts of the enclosure separated and with partial cuts and cutouts. For greater clarity, certain elements which are not part of the invention are not shown, such as the pivot axis of the doctor blade 14, the means for lifting and adjusting the tank 13, the drive member for the cylinder. engraved 12 wedged on the shaft 26, the means of supply, level control and circulation of the product, etc.

Sur le dessin, une presse rotative est destinée à reproduire sur un support mince 10 défilant en continu, les dessins, signes ou autres, gravés sur une forme cylindrique 12 à l'aide d'un produit contenu dans un bac 13. Pour ce faire la forme 12 est mise en contact intime avec le support 10 par un rouleau presseur 11 soumis à une pression hydraulique ou mécanique, après avoir été convenablement enduite avec le produit. Dans l'exemple représenté, il s'agit d'une presse héliographique, la forme 12 est gravée en creux, barbote directement dans le bac 13 et l' excès de produit est retenu par un organe complémentaire qui est une râcle d'essuyage 14 ; éventuellement, dans le cas d'un produit de forte viscosité, il peut exister un autre organe complémentaire constitué par une réglette ou râcle de distribution (non représentée) conformément à la demande de brevet français 81 24 026 co-pendante,au nom du même déposant. Cependant il doit être bien compris que la presse pourrait être typographique ou flexographique, la forme 12 étant alors un cylindre porte-clichés gravés en relief, ne barbotant pas dans le bac 13 et étant enduite avec le produit par l'intermédiaire d'au moins deux organes complémentaires (non représentés) à savoir un cylindre preneur barbotant dans le bac 13 et un cylindre toucheur transférant le produit du cylindre preneur aux reliefs de la forme 12.In the drawing, a rotary press is intended to reproduce on a thin support 10 continuously scrolling, the drawings, signs or others, engraved on a cylindrical shape 12 using a product contained in a tray 13. To do this the form 12 is brought into intimate contact with the support 10 by a pressure roller 11 subjected to hydraulic or mechanical pressure, after having been suitably coated with the product. In the example shown, this is a rotogravure press, the shape 12 is etched into a hollow, bubbled directly into the tank 13 and the excess product is retained by a complementary member which is a wiping rake 14 ; possibly, in the case of a product of high viscosity, there may exist another complementary member constituted by a strip or doctor blade (not shown) in accordance with French patent application 81 24 026 co-pending, in the name of the same depositor. However, it must be understood that the press could be typographic or flexographic, the form 12 then being a plate cylinder engraved in relief, not bubbling into the tank 13 and being coated with the product by means of at least two complementary members (not shown), namely a grab cylinder bubbling into tank 13 and a touch cylinder transferring the product from the grab cylinder to the reliefs of shape 12.

Une enceinte entoure la forme 12, les organes complémentaires (râcle 14 et râcle de distribution éventuelle ou cylindre preneur et cylindre toucheur) et le bac 13. Dans sa face supérieure est ménagée une fenêtre 19 constituant un passage pour la partie inférieure du rouleau presseur 11. L'enceinte est constituée de deux parties séparables pouvant être réunies de façon sensiblement étanche, à savoir une partie fixe 15 et une partie mobile 17. La partie fixe 15 est solidaire du bâti 16 de la rotative et porte les moyens (non représentés) d'amenée, de contrôle du niveau et de circulation du produit ainsi que ceux de réglage en hauteur du bac 13. La partie mobile 17 porte des paliers tels que 18 dans lesquels tourillonnent la forme 12 et les organes complémentaires (ic la râcle 14 dont l'axe de pivotement n'est pas représenté). Au moins une arrivée 20 d'air pulsé à température contrôlée est prévue à la basede la partie fixe 15a.An enclosure surrounds the form 12, the complementary members (doctor blade 14 and possible distribution doctor blade or take-up cylinder and touching cylinder) and the tank 13. In its upper face is provided a window 19 constituting a passage for the lower part of the pressure roller 11 The enclosure consists of two separable parts which can be joined together in a substantially leaktight manner, namely a fixed part 15 and a mobile part 17. The fixed part 15 is integral with the frame 16 of the rotary press and carries the means (not shown). supply, level control and product circulation as well as height adjustment of the bin 13. The movable part 17 carries bearings such as 18 in which rotate the shape 12 and the complementary members (ic the scraping 14 whose the pivot axis is not shown). At least one supply of forced air at a controlled temperature is provided at the base of the fixed part 15a.

En écartant la partie mobile 17 de la partie fixe 15, après avoir abaissé le bac 13, l'on a directement accès à la forme 12 pour en effectuer le changement. Par ailleurs, si des réglages sont à prévoir en cours de travail pour les organes complémentaires, ce qui est le cas sur une presse héliographique pour la râcle 14 et la râcle de distribution éventuelle (non représentée), on accède aux commandes de réglage par des ouvertures qui sont munies de moyens d'obturation tels qu'un abattant 21 sur la face supérieure de la partie 17 et/ou un panneau coulissant 22 sur la face avant de ladite partie.By moving the movable part 17 away from the fixed part 15, after lowering the tray 13, there is direct access to the form 12 to effect the change. Furthermore, if adjustments are to be expected during work for the complementary members, which is the case on a rotogravure press for the doctor blade 14 and the doctor blade if any (not shown), the adjustment commands are accessed by openings which are provided with sealing means such as a flap 21 on the upper face of the part 17 and / or a sliding panel 22 on the front face of said part.

Dans l'exemple représenté le plan de jonction des parties fixe 15 et mobile 17 passe par l'axe du rouleau présseur 11, c'est dire qu'en position de travail il passe également par l'axe de la forme 12 et que les paliers 18 solidaires de la partie mobile 17 font saillie vers l' arrière. Sur les côtés latéraux de la partie fixe 15 sont alors ménagés des encoches 28a, 28b dans lesquelles viennent se loger les parties arrière desdits paliers. Avec cette disposition la fenêtre 19 de la face supérieure de l'enceinte est formée par deux échancrures en regard prévues respectivement sur les faces supérieures de chacune des parties fixe 15 et mobile 17.In the example shown, the junction plane of the fixed 15 and mobile 17 parts passes through the axis of the pressure roller 11, that is to say that in the working position it also passes through the axis of the form 12 and that the bearings 18 integral with the movable part 17 protrude rearward. On the lateral sides of the fixed part 15 are then provided notches 28a, 28b in which are housed the rear parts of said bearings. With this arrangement, the window 19 of the upper face of the enclosure is formed by two notches facing each other. views respectively on the upper faces of each of the fixed 15 and mobile 17 parts.

Ici la partie fixe 15 de l'enceinte est un caisson parallélépipédique ouvert vers l'avant et dont la face inférieure 23 saille largement vers l'avant pour obturer par-dessous la partie mobile 17 qui se présente comme un tiroir sans fond ni face arrière. De part et d'autre de cette partie mobile 17 sont disposés respectivement deux blocs porteurs 24a, 24b reliés à la dite partie par l'axe 26 de la forme 12, éventuellement les axes des organes complémentaires (non représentés) et des barres de liaison telles que 29a, 29b. En position de travail ces blocs porteurs 24a, 24b viennent s'encastrer dans des logements 25a, 25b prévus dans les jambages du bâti 16 et y sont fermement fixés ou verrouillés. L'axe 26 de la forme gravée 12 et les axes des organes complémentaires devant être entraînés en rotation, quand ils existent, traversent les blocs 24a, 24b à travers des paliers 27 pour déborder le bâti 16, au moins sur l'un des côtés, pour recevoir un organe d'entraînement.Here the fixed part 15 of the enclosure is a parallelepipedic box open towards the front and the lower face 23 of which projects widely towards the front to close off below the mobile part 17 which is presented as a drawer without bottom or rear face. . On each side of this movable part 17 are respectively arranged two carrier blocks 24a, 24b connected to said part by the axis 26 of the form 12, possibly the axes of the complementary members (not shown) and connecting bars such as 29a, 29b. In the working position, these support blocks 24a, 24b are fitted into housings 25a, 25b provided in the legs of the frame 16 and are firmly fixed or locked there. The axis 26 of the engraved shape 12 and the axes of the complementary members to be rotated, when they exist, pass through the blocks 24a, 24b through bearings 27 to extend beyond the frame 16, at least on one of the sides , to receive a drive member.

Bien entendu des modifications de détail peuvent être apportées à la structure générale qui vient d'être décrite sans que l'on sorte du domaine de l'invention, notamment en ce qui concerne les ouvertures pour les visites et les réglages, les arrivées d'air pulsé (qui peuvent être disposées sur le fond 23 de la partie fixe 15), les moyens de guidage et d'encastrement des blocs porteurs 24a et 24b, etc.Of course, modifications of detail can be made to the general structure which has just been described without departing from the scope of the invention, in particular with regard to the openings for visits and adjustments, the arrivals of forced air (which can be arranged on the bottom 23 of the fixed part 15), the means for guiding and fitting the carrier blocks 24a and 24b, etc.

Lorsque le produit nécessite d'opérer à une température assez différente de la température ambiante, toutes les parois des parties fixe et mobile de l'enceinte sont calorifugées (y compris les moyens d' obturation tels que 21 et 22 des ouvertures d'accès).When the product requires operating at a temperature quite different from the ambient temperature, all the walls of the fixed and mobile part of the enclosure are insulated (including the means of closing such as 21 and 22 of the access openings) .

L'enceinte telle que prévue dans la présente invention peut être installée assez aisément sur des presses existantes.The enclosure as provided in the present invention can be installed quite easily on existing presses.
