Abstract
Description
La présente invention a trait à un manchon porte-clichés perfectionné pour machine à imprimer en flexographie.The present invention relates to an improved printing sleeve for a flexographic printing machine.
Ce type de machine comporte actuellement des manchons imprimeurs réalisés à partir d'un manchon mince en métal ou autre, autour duquel est effectué par moulage le revêtement de travail en photopolymère ou en caoutchouc, pour être rectifié ensuite au développement désiré avant d'être gravé.This type of machine currently includes printing sleeves made from a thin metal or other sleeve, around which is made by molding the working coating of photopolymer or rubber, to be then rectified to the desired development before being engraved. .
La conception de ces manchons imprimeurs nécessitent obligatoirement l'utilisation d'un cylindre d'acier porte-manchon adapté à chaque développement d'impression. C'est ainsi que pour une machine à imprimer en six couleurs offrant des développements d'impression variables de cm en cm, depuis 300 mm de développement jusqu'à 1000 mm, il faut 350 cylindres porte-manchon.The design of these printing sleeves necessarily requires the use of a sleeve-carrying steel cylinder adapted to each printing development. Thus for a printing machine in six colors offering variable printing developments from cm to cm, from 300 mm development to 1000 mm, 350 sleeve cylinders are required.
Ces cylindres sont coûteux puisqu'ils représentent plus de 15 % du prix de la machine à imprimer,lourds à manipuler, et encombrants à stocker du fait de leur nombre.These cylinders are expensive since they represent more than 15% of the price of the printing machine, heavy to handle, and bulky to store because of their number.
On peut, certes, réduire un peu leur nombre en utilisant des manchons garnis d'un revêtement en caoutchouc dont l'épaisseur peut être suffisante pour accepter plusieurs rectifications permettant d'obtenir ainsi des développements différents avec le même manchon, mais la réduction n'est pas très importante et d'autres inconvénients apparaissent tels que la longueur du temps de cuisson (24 h) du revêtement, et les pertes de propriétés mécaniques à chaque opération de rectification.It is certainly possible to reduce their number a little by using sleeves fitted with a rubber coating, the thickness of which may be sufficient to accept several corrections, thus making it possible to obtain different developments with the same sleeve, but the reduction does not is not very important and other drawbacks appear such as the length of the baking time (24 h) of the coating, and the loss of mechanical properties with each grinding operation.
Le but de l'invention est de palier ces divers inconvénients en proposant un manchon porte-clichés perfectionné apte à un grand nombre de rectifications permettant d'obtenir un nombre important de développements, plus léger, moins coûteux et plus pratique à mettre en place et, ce, tout en conservant au manchon des caractéristiques mécaniques optimales, notamment la dureté et la qualité d'impression du revêtement de travail.The object of the invention is to overcome these various drawbacks by proposing an improved plate-holding sleeve suitable for a large number of corrections making it possible to obtain a large number of developments, lighter, less costly and more practical to install and , this while retaining optimal mechanical characteristics at the sleeve, in particular the hardness and the printing quality of the working coating.
A cet effet, l'invention a pour objet un manchon porte-clichés pour cylindre d'impression flexographique muni à sa périphérie d'orifices d'envoi d'air sous pression en vue du montage du manchon sur le cylindre, caractérisé en ce qu'il est constitué :
- d'un manchon tubulaire interne en matériau légèrement expansible radialement,
- d'un manchon tubulaire externe porteur d'une surface de travail en un matériau offrant de grandes légèreté, résistance mécanique et stabilité dimensionnelle et d'une épaisseur importante permettant d'obtenir par rectification un grand nombre de développements différents, et
- d'un manchon intermédiaire en un matériau élastique susceptible d'absorber les expansions, déformations du manchon interne,
lesdits manchons étant solidarisés entre eux par tous moyens appropriés.To this end, the subject of the invention is a printing plate sleeve for a flexographic printing cylinder provided at its periphery with holes for sending pressurized air for mounting the sleeve on the cylinder, characterized in that 'it consists :
- an internal tubular sleeve of slightly radially expandable material,
- an external tubular sleeve carrying a work surface made of a material offering great lightness, mechanical strength and dimensional stability and a large thickness allowing a large number of different developments to be obtained by grinding, and
- an intermediate sleeve made of an elastic material capable of absorbing expansions, deformations of the internal sleeve,
said sleeves being joined together by any appropriate means.
Un tel manchon porte-clichés permet d'offrir pour un même diamètre de cylindre porte-manchon, une gamme très étendue de manchons présentant des développements différents, du fait de l'épaisseur importante du manchon externe portant la surface de travail, sans détérioration des qualités de dureté et de stabilité dimensionnelle notamment du matériau dudit manchon externe lors des opérations de rectification nécessaires à l'obtention des différents développements.Such a plate sleeve makes it possible to offer, for the same diameter of the sleeve cylinder, a very wide range of sleeves having different developments, due to the large thickness of the external sleeve carrying the working surface, without deterioration of the qualities of hardness and dimensional stability, in particular of the material of said external sleeve during the grinding operations necessary for obtaining the various developments.
Ceci permet de réduire très substantiellement le nombre de cylindres porte-manchon de diamètres différents de la machine à imprimer.This enables the number of sleeve cylinders of different diameters of the printing machine to be reduced very substantially.
Le nombre de 350 cylindres rappelé plus haut pour une machine standard à 6 couleurs devant imprimer des développements de 300 mm à 1000 mm peut ainsi être ramené à 24.The number of 350 cylinders mentioned above for a standard 6-color machine to print developments from 300 mm to 1000 mm can thus be reduced to 24.
En outre, les manchons selon l'invention sont substantiellement plus légers et plus faciles à mettre en place et enlever du fait de la présence d'un manchon interne légèrement expansible et d'une couche intermédiaire entre manchons interne et externe, en matériau élastique évitant au manchon externe toute déformation.In addition, the sleeves according to the invention are substantially lighter and easier to put on and remove due to the presence of a slightly expandable inner sleeve and an intermediate layer between inner and outer sleeves, made of elastic material avoiding any deformation to the outer sleeve.
D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un même mode de réalisation selon l'invention, description donnée à titre d'exemple uniquement et en regard du dessin annexé sur lequel la figure unique représente schématiquement en coupe axiale un cylindre d'une machine à imprimer en flexographie sur lequel est en cours d'enfilage un manchon porte-clichés conforme à l'invention.Other characteristics and advantages will emerge from the description which follows of the same embodiment according to the invention, description given by way of example only and with reference to the appended drawing in which the single figure schematically represents in axial section a cylinder of a flexographic printing machine on which a printing plate sleeve in accordance with the invention is being threaded.
Sur cette figure unique, on a représenté en 1 un cylindre porte-manchon de type connu, comportant une cavité interne 2 susceptible de recevoir de l'air comprimé introduit par l'intermédiaire d'un perçage 3 ménagé dans l'un des axes d'extrémité 4 du cylindre 1.In this single figure, there is shown at 1 a sleeve-type cylinder known type, comprising an internal cavity 2 capable of receiving compressed air introduced through a bore 3 formed in one of the axes d end 4 of cylinder 1.
Des trous 5 d'éjection d'air sont ménagés dans la paroi du cylindre suivant deux alignements circonférentiels dans le mode de réalisation représenté, en vue de permettre la dilatation de la surface interne du manchon porte-clichés lorsque celui-ci est enfilé sur le cylindre 1.
Conformément à l'invention, le manchon porte-clichés est constitué d'un manchon cylindrique interne 6 en matériau légèrement expansible radialement.According to the invention, the plate-holding sleeve consists of an internal cylindrical sleeve 6 made of slightly radially expandable material.
Par exemple, le manchon 6 est en matériau composite formé de fibres de verre noyée dans une matrice de résine époxy, d'une épaisseur de l'ordre de 1 à 2 millimètres environ.For example, the sleeve 6 is made of composite material formed from glass fibers embedded in an epoxy resin matrix, with a thickness of the order of approximately 1 to 2 millimeters.
Le diamètre interne du manchon 6 correspond au diamètre externe du cylindre 1.The internal diameter of the sleeve 6 corresponds to the external diameter of the cylinder 1.
Le manchon interne 6 est entouré par un manchon intermédiaire cylindrique 7 en matériau élastique absorbant les expansions et déformations du manchon interne 6 lors de l'enfilage de ce dernier sur le cylindre 1.The internal sleeve 6 is surrounded by a cylindrical
Par exemple, le matériau du manchon 7 est un élastomère d'une dureté appropriée, par exemple d'environ 80 à 85 shore A, le manchon 7 ayant une épaisseur de quelques millimètres, 3 à 5 notamment.For example, the material of the
Le manchon intermédiaire 7 est entouré d'un manchon externe cylindrique 8 porteur du revêtement ou surface de travail (non représenté sur la figure).The
Le matériau du manchon externe 8 doit être léger, d'une grande rigidité et indilatable afin de conserver une excellente stabilité dimensionnelle malgré les sollicitations physiques exercées, d'une part, par les manchons sous-jacents, 6,7 lors des opérations de montage sur le cylindre 1 et de démontage et, d'autre part, lors des rectifications du diamètre externe du manchon 8 en vue de l'obtention de développements différents.The material of the external sleeve 8 must be light, of great rigidity and indilatable in order to maintain an excellent dimensional stability despite the physical stresses exerted, on the one hand, by the underlying sleeves, 6,7 during the assembly operations. on the cylinder 1 and disassembly and, on the other hand, during the rectifications of the external diameter of the sleeve 8 with a view to obtaining different developments.
A cet effet, le matériau du manchon 8 est, par exemple, une résine thermodurcissable telle qu'une résine époxy, chargée, de dureté appropriée, permettant d'usiner avec précision et facilité la surface externe du manchon 8 et d'obtenir un surfaçage lisse.For this purpose, the material of the sleeve 8 is, for example, a thermosetting resin such as an epoxy resin, loaded, of suitable hardness, making it possible to precisely and easily machine the external surface of the sleeve 8 and to obtain a surfacing. smooth.
Le matériau du manchon 8 peut, également, faire l'objet d'un traitement de surface pour obtenir un durcissement local permettant une rectification au diamètre désiré de meilleure qualité.The material of the sleeve 8 can also be subjected to a surface treatment to obtain a local hardening allowing rectification to the desired diameter of better quality.
L'épaisseur du manchon 8 est importante, par exemple de l'ordre de plusieurs millimètres, 5 à 15 notamment, en sorte d'accepter plusieurs rectifications en vue de l'obtention d'une large gamme de manchons de même diamètre intérieur, s'adaptant donc sur un même cylindre 1, et de développements différents.The thickness of the sleeve 8 is large, for example of the order of several millimeters, 5 to 15 in particular, so as to accept several corrections in order to obtain a wide range of sleeves of the same internal diameter, s 'therefore adapting to the same cylinder 1, and of different developments.
La solidarisation entre les manchons 6 et 7, d'une part, et 7 et 8, d'autre part, est assurée par tous moyens appropriés, notamment un collage.The connection between the
Sur le manchon externe 8 est enfin rapporté le revêtement ou surface de travail. A cet effet, on peut rapporter sur le manchon 8, par extrusion par exemple, un manchon en élastomère gravé au laser et définissant ainsi la surface de travail.On the external sleeve 8 is finally attached the coating or work surface. For this purpose, it is possible to attach to the sleeve 8, by extrusion for example, an elastomer sleeve engraved with the laser and thus defining the working surface.
On peut aussi recouvrir le manchon 8 d'un manchon en matériau composite, par exemple fibres de verre + résine époxy, garni de photopolymère qui sera gravé par la suite.It is also possible to cover the sleeve 8 with a sleeve made of composite material, for example glass fibers + epoxy resin, lined with photopolymer which will be etched subsequently.
On peut, enfin, rapporter directement sur le manchon 8 des clichés imprimeurs, fixés par collage, la précision de mise en place de ces clichés pouvant avantageusement être facilitée et améliorée grâce à des lignes gravées longitudinalement et radialement sur la surface externe du manchon 8, ces lignes étant protégées par une pellicule de résine thermodurcissable compatible avec le matériau de collage des clichés imprimeurs.We can, finally, report directly on the sleeve 8 printing plates, fixed by gluing, the precision of setting place of these plates can advantageously be facilitated and improved by lines etched longitudinally and radially on the external surface of the sleeve 8, these lines being protected by a film of thermosetting resin compatible with the bonding material of printing plates.
Le manchon de l'invention se met en place sur le cylindre 1 comme les manchons traditionnels, les couches 6,7 absorbant, comme illustré par les flèches 9 sur la figure, les sollicitations radiales vers l'extérieur exercées par l'air sous pression du coussin d'air interposé entre le cylindre 1 et le manchon interne 6.The sleeve of the invention is put in place on the cylinder 1 like the traditional sleeves, the
L'invention permet par ailleurs de réaliser des manchons d'un poids réduit dans un rapport de 1 à 3 en comparaison avec des manchons traditionnels de même développement, plus faciles à manipuler et d'un prix de revient moindre.The invention also makes it possible to produce sleeves with a reduced weight in a ratio of 1 to 3 in comparison with traditional sleeves of the same development, which are easier to handle and have a lower cost price.
Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes notamment en ce qui concerne la nature des matériaux utilisés pour les différents manchons ou couches 6,7,8, ainsi que les épaisseurs de ces derniers.Finally, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all variants thereof, in particular as regards the nature of the materials used for the various sleeves or
