Description

La présente invention concerne un dispositif d'essuyage d'une machine pour l'impression en taille-douce comprenant un cylindre d'essuyage et une installation pour le nettoyage en continu dudit cylindre, cette installation comportant un récipient pour la réception du liquide de nettoyage qui agit en permanence sur le cylindre d'essuyage et des éléments de nettoyage au contact de la périphérie du cylindre d'essuyage comprenant, dans le sens de rotation de ce cylindre, un premier élément de nettoyage, qui enlève la plus grande partie de l'encre du cylindre d'essuyage, suivi, à des distances définies, de plusieurs autres éléments constitués par des brosses et/ou des râcles, au moins une rangée de buses parallèle à l'axe du cylindre d'essuyage, les buses étant disposées pour éjecter le liquide de nettoyage dans la zone de la région de contact dudit premier élément de nettoyage avec le cylindre d'essuyage.The present invention relates to a device for wiping a machine for intaglio printing comprising a wiping cylinder and an installation for the continuous cleaning of said cylinder, this installation comprising a container for receiving the cleaning liquid. which acts permanently on the wiping cylinder and cleaning elements in contact with the periphery of the wiping cylinder comprising, in the direction of rotation of this cylinder, a first cleaning element, which removes most of the ink from the wiping cylinder, followed, at defined distances, by several other elements constituted by brushes and / or scrapers, at least one row of nozzles parallel to the axis of the wiping cylinder, the nozzles being arranged for ejecting the cleaning liquid in the region of the region of contact of said first cleaning element with the wiping cylinder.

Selon le brevet suisse No 596 988 de la déposante, on connaît déjà une installation de nettoyage du cylindre d'essuyage dans laquelle le premier élément de nettoyage est constitué par une râcle en acier formant un angle aigu avec la périphérie du cylindre située à la suite de cette râcle dans le sens de rotation du cylindre, et destinée à enlever la plus grande partie de l'encre. Bien que cette râcle soit tout à fait efficace, puisqu'elle permet d'enlever à elle seule pratiquement 90% de l'encre de la surface du cylindre d'essuyage, on a pu constater à l'usage que, du fait du frottement important entre la râcle et le cylindre, frottement qui est renforcé par l'inclinaison à angle aigu de la râcle par rapport à la périphérie du cylindre d'essuyage, la surface du cylindre subit de très grandes forces d'usure qui risquent de l'endommager, d'autant plus que cette surface est en matière synthétique, notamment en PVC. En outre, on a constaté que ladite râcle devient très vite tranchante, ce qui accentue l'usure du cylindre d'essuyage et oblige l'utilisateur à remplacer cette râcle toutes les 24 heures environ.According to Swiss patent No. 596 988 of the applicant, there is already known an installation for cleaning the wiping cylinder in which the first cleaning element is constituted by a steel scraper forming an acute angle with the periphery of the cylinder located after of this doctor blade in the direction of rotation of the cylinder, and intended to remove most of the ink. Although this doctor blade is quite effective, since it alone removes practically 90% of the ink from the surface of the wiping cylinder, it has been found in use that, due to friction important between the doctor blade and the cylinder, friction which is reinforced by the angle inclination acute scraping with respect to the periphery of the wiping cylinder, the surface of the cylinder undergoes very great wear forces which risk damaging it, all the more so since this surface is made of synthetic material, in particular PVC. In addition, it was found that said doctor blade very quickly becomes sharp, which increases the wear of the wiping cylinder and forces the user to replace this doctor blade about every 24 hours.

La présente invention se propose de pallier les inconvénients inhérents à une râcle en acier en ménageant la surface du cylindre d'essuyage tout en diminuant le coût de l'entretien.The present invention proposes to overcome the drawbacks inherent in a steel doctor blade by sparing the surface of the wiping cylinder while reducing the cost of maintenance.

A cet effet, l'installation selon l'invention est caractérisée par le fait que le premier élément de nettoyage est en matière textile sous forme de bande qui est montée repliée sur elle-même sur et le long d'un support rigide, de manière à déborder de celui-ci. Cette matière textile est de préférence en fibres synthétiques poreuses.To this end, the installation according to the invention is characterized in that the first cleaning element is made of textile material in the form of a strip which is mounted folded back on itself on and along a rigid support, so to overflow from it. This textile material is preferably made of porous synthetic fibers.

Jusqu'ici, l'homme du métier était convaincu que pour enlever la plus grande partie de l'encre le premier élément de nettoyage devait obligatoirement être en matériau rigide, solide comme de l'acier, c'est pourquoi la râcle en acier a été considérée comme nécessaire pendant de nombreuses années. Cependant, d'une manière surprenante, on a découvert que le même effet était produit par un élément en simple matière textile en évitant les désavantages de la râcle en acier.Until now, those skilled in the art were convinced that in order to remove most of the ink, the first cleaning element had to be made of rigid material, solid like steel, which is why the steel scraper was been considered necessary for many years. However, surprisingly, it has been discovered that the same effect is produced by a simple textile element while avoiding the disadvantages of the steel scraper.

On obtient ainsi un premier élément de nettoyage aussi efficace qu'une râcle rigide mais qui, grâce à sa souplesse, ne risque pas de détériorer la surface du cylindre d'essuyage, donc qui permet d'augmenter la durée de vie de celui-ci. Un autre avantage est que l'usure étant moindre qu'avec une râcle en acier, la durée de vie de l'élément de nettoyage lui-même est plus longue, de l'ordre de huit jours, ce qui est nettement plus économique pour l'utilisateur.A first cleaning element is thus obtained which is as effective as a rigid scraper but which, thanks to its flexibility, does not risk damaging the surface of the wiping cylinder, which therefore increases the life of the latter. Another advantage is that the wear being less than with a steel scraper, the life of the cleaning element itself is longer, of the order of eight days, which is clearly more economical for the user.

Le dessin annexé représente, à titre d'exemple, une forme d'éxécution de l'invention.The accompanying drawing shows, by way of example, an embodiment of the invention.

La figure 1 représente une vue schématique du dispositif de nettoyage du cylindre d'essuyage.FIG. 1 represents a schematic view of the device for cleaning the wiping cylinder.

La figure 2 est une vue partielle agrandie de la zone de contact du premier élément de nettoyage avec le cylindre d'essuyage.Figure 2 is an enlarged partial view of the contact area of the first cleaning element with the wiping cylinder.

Le dispositif d'essuyage comporte un cylindre d'essuyage 1, tournant dans le sens de la flèche F, destiné à être en contact permanent avec le cylindre porte-plaques non représenté, le sens de rotation périphérique de ce cylindre d'essuyage 1 étant opposé à celui du cylindre porte-plaques. Ce cylindre d'essuyage 1 est disposé partiellement à l'intérieur d'un récipient 2 dans lequel est montée l'installation de nettoyage. La surface du cylindre d'essuyage 1 est en matériau synthétique, notamment en PVC, ce qui assure un bon essuyage du cylindre porte-plaques.The wiping device comprises a wiping cylinder 1, rotating in the direction of arrow F, intended to be in permanent contact with the plate cylinder not shown, the peripheral direction of rotation of this wiping cylinder 1 being opposite to that of the plate cylinder. This wiping cylinder 1 is partially arranged inside a container 2 in which the cleaning installation is mounted. The surface of the wiping cylinder 1 is made of synthetic material, in particular PVC, which ensures good wiping of the plate cylinder.

L'installation de nettoyage comporte, d'une manière connue en soi, plusieurs éléments de nettoyage constitués, dans l'exemple considéré, par une râcle 3 formant un angle obtus avec la périphérie du cylindre 1 située à la suite de cette râcle dans le sens de rotation dudit cylindre, et par des brosses 4 disposées à distance les une des autres autour de la périphérie du cylindre 1.The cleaning installation comprises, in a manner known per se, several cleaning elements constituted, in the example considered, by a doctor blade 3 forming an obtuse angle with the periphery of the cylinder 1 located following this doctor blade direction of rotation of said cylinder, and by brushes 4 arranged at a distance from one another around the periphery of cylinder 1.

Ces brosses 4, et le cas échéant la râcle 3, sont montées dans le récipient 2 sur un rail commun permettant de les approcher ou de les éloigner simultanément de la surface du cylindre d'essuyage 1. Des buses de giclage d'un liquide de nettoyage, non représentées, sont associées à chacune de ces brosses 4 de telle manière que la région du cylindre 1 située avant la zone de contact de chaque élément de nettoyage soit mouillée.These brushes 4, and if necessary the doctor blade 3, are mounted in the container 2 on a common rail allowing them to be approached or removed simultaneously from the surface of the wiping cylinder 1. Nozzles for spraying a liquid of cleaning, not shown, are associated with each of these brushes 4 in such a way that the region of the cylinder 1 situated before the contact zone of each cleaning element is wetted.

Avant les brosses 4 et la râcle 3, dans le sens de rotation du cylindre d'essuyage 1, est monté un premier élément de nettoyage 5 constitué par une matière textile de fibres synthétiques poreuses, d'une épaisseur comprise entre 5 et 20 mm, de préférence 10 mm, commercialisée par exemple par la société 3M sous le nom "Scotch-Brite" ou "tampon à main". Cette matière textile est sous forme d'une bande dont la dimension dans le sens axial du cylindre correspond à la longueur de celui-ci pour que toute la surface soit couverte, et qui est montée, repliée sur elle-même (figure 2), sur et le long d'un support 6 de manière à dépasser de celui-ci. L'inclinaison du support 6 est ajustable pour régler la pression de contact entre la bande de matière textile et la surface du cylindre 1, ce support 6 étant de même configuration que le porte-râcle qui, dans les installations précédentes, était destiné à porter la râcle en acier. Cet élément 5 qui est fixé de n'importe quelle manière connue sur le support 6, est prévu pour s'appliquer tangentiellement sur toute la longueur du cylindre d'essuyage 1 lors de la rotation de celui-ci, en formant un angle aigu avec la périphérie du cylindre située à la suite de cet élément dans le sens de rotation du cylindre, et pour frotter sa surface de manière à enlever environ 90% de la quantité d'encre présente à la surface du cylindre d'essuyage. Au dessus du premier élément de nettoyage 5 est prévue une rangée de buses de giclage 7 dirigées juste avant la zone de contact dudit élément 5 avec le cylindre 1. Dans le support 6 est prévue une deuxième rangée de buses 8 dont les bouches sont dirigées vers l'intérieur du pli formé par le premier élément de nettoyage 5. Ces buses 7 et 8 sont destinées à envoyer sous pression un liquide de nettoyage qui, d'une part, déterge l'encre et, d'autre part, mouille et rince en permanence l'élément de nettoyage 5, ce qui évite l'encrassement de celui-ci lors du frottement.Before the brushes 4 and the doctor blade 3, in the direction of rotation of the wiping cylinder 1, is mounted a first cleaning element 5 consisting of a textile material of porous synthetic fibers, with a thickness of between 5 and 20 mm, preferably 10 mm, sold for example by the company 3M under the name "Scotch-Brite" or "hand pad". This textile material is in the form of a strip whose dimension in the axial direction of the cylinder corresponds to the length of the latter so that the entire surface is covered, and which is mounted, folded back on itself (FIG. 2), on and along a support 6 so as to protrude therefrom. The inclination of the support 6 is adjustable to adjust the contact pressure between the strip of textile material and the surface of the cylinder 1, this support 6 having the same configuration as the doctor blade which, in the previous installations, was intended to carry the steel scraper. This element 5 which is fixed in any known manner to the support 6, is intended to apply tangentially over the entire length of the wiping cylinder 1 during the rotation thereof, forming an acute angle with the periphery of the cylinder located after this element in the direction of rotation of the cylinder, and to rub its surface so as to remove approximately 90% of the quantity of ink present on the surface of the wiping cylinder. Above the first cleaning element 5 is provided a row of spray nozzles 7 directed just before the contact zone of said element 5 with the cylinder 1. In the support 6 is provided a second row of nozzles 8 whose mouths are directed towards inside the fold formed by the first cleaning element 5. These nozzles 7 and 8 are intended to send under pressure a cleaning liquid which, on the one hand, deterges the ink and, on the other hand, wets and rinses permanently cleaning element 5, which prevents fouling thereof during friction.

Le liquide de nettoyage provenant des buses 7, 8 et des buses associées aux brosses 4 est récolté dans le récipient 2 et s'écoule à travers des orifices de sortie 11 de manière que le cylindre d'essuyage 1 ne se trouve pas immergé dans le liquide souillé. Une paroi de séparation 2' dans le récipient 2 permet de séparer le liquide de nettoyage provenant des buses 7, 8, qui est souillé par la plus grande quantité d'encre du liquide moins sale provenant des buses associées aux brosses 4.The cleaning liquid from the nozzles 7, 8 and the nozzles associated with the brushes 4 is collected in the container 2 and flows through outlet orifices 11 so that the wiping cylinder 1 is not immersed in the soiled liquid. A separation wall 2 ′ in the container 2 makes it possible to separate the cleaning liquid coming from the nozzles 7, 8, which is soiled by the greatest amount of ink from the less dirty liquid coming from the nozzles associated with the brushes 4.

Les résidus d'encre à la surface du cylindre d'essuyage 1 sont enlevés grâce à l'action de la râcle 3 pour diminuer la contamination des brosses et le nettoyage complet est achevé par les brosses 4, en combinaison avec le liquide de nettoyage éjecté par les buses qui leur sont associées. Enfin, après les brosses 4, est prévue une lame rigide 9, notamment en acier, qui essuie le cylindre et le sèche partiellement, et le séchage complet est réalisé par l'action d'une soufflerie d'air 10. Ainsi, la surface du cylindre d'essuyage 1 qui va entrer à nouveau en contact avec le cylindre porte-plaque est nette de toute trace d'encre et prête à jouer son rôle d'essuyage.The ink residue on the surface of the wiping cylinder 1 is removed by the action of the scraper 3 to reduce the contamination of the brushes and the complete cleaning is completed by the brushes 4, in combination with the ejected cleaning liquid. by the nozzles associated therewith. Finally, after the brushes 4, a rigid blade 9 is provided, in particular made of steel, which wipes the cylinder and dries it partially, and complete drying is carried out by the action of an air blower 10. Thus, the surface of the wiping cylinder 1 which will again come into contact with the plate-holding cylinder is free of any trace of ink and ready to play its role of wiping.
