Description
La présente invention concerne un dispositif de fixation d'un manchon sur un axe d'un cylindre porte-clichés d'une machine d'impression.The present invention relates to a device for fixing of a sleeve on an axis of a plate cylinder of a printing machine.
On sait que les cylindres porte-clichés des machines d'impression sont habituellement constitués d'un arbre cylindrique ou conique, sur lequel est fixé un manchon portant, sur sa partie périphérique externe, la gravure destinée à réaliser l'impression.We know that the plate cylinders of machines print usually consist of a tree cylindrical or conical, on which a sleeve is fixed bearing, on its external peripheral part, the engraving intended for printing.
On sait qu'il est important, sur de telles machines, que l'utilisateur soit en mesure de remplacer rapidement et facilement un manchon par un autre.We know that it is important, on such machines, that the user is able to quickly replace and easily one sleeve by another.
On a ainsi proposé d'assurer la fixation du manchon d'impression sur l'arbre cylindrique au moyen d'un frettage. Pour ce faire, on exerce sur la face interne du manchon une contrainte apte à provoquer une dilatation de celui-ci qui permet alors de l'emmancher sur l'arbre. Une fois l'emmanchement réalisé, il suffit de supprimer la contrainte qui assure la dilatation du manchon pour que celui-ci se trouve alors pressé fortement sur l'arbre.It has thus been proposed to secure the sleeve printing on the cylindrical shaft by means of a hooping. To do this, one exerts on the internal face of the sleeve a constraint capable of causing it to expand which then allows it to be fitted onto the tree. Once fitting done, just remove the constraint which ensures the expansion of the sleeve so that it finds then pressed strongly on the tree.
La déformation du manchon est habituellement obtenue en insufflant de l'air sous pression entre la surface interne de ce dernier et la surface externe de l'arbre, au travers de trous de faible diamètre prévus dans ce dernier.The deformation of the sleeve is usually obtained by blowing pressurized air between the internal surface of the latter and the outer surface of the tree, through small diameter holes provided in the latter.
Une telle déformation, de l'ordre de quelques dixièmes de millimètre pour des manchons métalliques, et de quelques millimètres pour des manchons en matériaux composites, est obtenue sans difficulté lorsque les manchons ont une faible épaisseur. Such deformation, on the order of a few tenths millimeters for metal sleeves, and a few millimeters for sleeves made of composite materials, is obtained without difficulty when the sleeves have a low thickness.
On a également proposé d'assurer la fixation d'un manchon sur son arbre en provoquant un gonflement de celui-ci après sa mise en place (voir par exemple DE-B-1 301 940), sous l'effet d'une pression hydraulique importante (de l'ordre d'environ 2.107 Pa) et en maintenant cette pression au cours du fonctionnement. Un tel mode de fixation permet d'obtenir un serrage parfait du manchon sur l'arbre, ainsi qu'une-très bonne concentricité du manchon par rapport à celui-ci en cours d'utilisation. Cependant, le gonflement de l'arbre a pour effet de provoquer une déformation du manchon qui, même lorsqu'elle est légère, nuit à la bonne précision du dispositif d'impression. De plus, dans un tel dispositif, la nécessité de maintenir, en cours de fonctionnement, la pression hydraulique de commande, implique sur le plan pratique de la mise en oeuvre de faire appel à des dispositifs particulièrement onéreux.It has also been proposed to secure a sleeve on its shaft by causing it to swell after it has been put in place (see for example DE-B-1 301 940), under the effect of pressure significant hydraulic (around 2.10 7 Pa) and maintaining this pressure during operation. Such a method of fixing makes it possible to obtain perfect tightening of the sleeve on the shaft, as well as very good concentricity of the sleeve with respect to the latter in use. However, the swelling of the shaft has the effect of causing a deformation of the sleeve which, even when it is slight, affects the good accuracy of the printing device. In addition, in such a device, the need to maintain, during operation, the hydraulic control pressure, implies in practical terms of implementation to use particularly expensive devices.
L'invention a pour but de proposer un moyen permettant d'assurer la fixation d'un manchon d'impression sur son arbre d'entraínement, permettant d'éviter d'une part, la déformation du manchon et, d'autre part, de devoir maintenir la pression hydraulique assurant le maintien du manchon sur son arbre en cours de fonctionnement.The object of the invention is to propose a means allowing securing a printing sleeve on its shaft on the one hand, avoiding the deformation of the sleeve and, on the other hand, of having to maintain the hydraulic pressure ensuring that the sleeve remains on its tree during operation.
La présente invention a ainsi pour objet un dispositif de maintien d'un manchon, notamment un manchon anilox, sur un arbre cylindrique d'entraínement, caractérisé en ce que :
- il comporte, entre le manchon et l'arbre, un fourreau déformable,
- la surface de l'arbre est creusée d'une série de cavités, séparées par des surfaces de maintien sur lesquelles le fourreau est en appui,
- le fourreau est apte à se déformer de façon qu'il puisse posséder deux positions, à savoir une position d'assemblage, dans laquelle au moins une partie de sa surface, dite zone déformable, à savoir celle située en regard des cavités, se déforme dans celles-ci sous l'action d'une contrainte, et une position de repos dans laquelle la zone déformable a repris, au moins en partie, sa forme initiale, de façon à être appliquée contre la surface interne du manchon,
- il comporte des moyens aptes à assurer la déformation dans le sens radial des zones déformables du fourreau.
- it comprises, between the sleeve and the shaft, a deformable sheath,
- the surface of the tree is hollowed out by a series of cavities, separated by retaining surfaces on which the sheath is supported,
- the sheath is able to deform so that it can have two positions, namely an assembly position, in which at least part of its surface, called the deformable zone, namely that located opposite the cavities, deforms in these under the action of a stress, and a rest position in which the deformable zone has resumed, at least in part, its initial shape, so as to be applied against the internal surface of the sleeve,
- it comprises means capable of ensuring the deformation in the radial direction of the deformable zones of the sheath.
Dans un mode de mise en oeuvre de l'invention les moyens aptes à assurer la déformation des zones déformables du fourreau, sont constitués de moyens permettant d'exercer une surpression sur la face externe de celui-ci.In one embodiment of the invention, the means capable of ensuring the deformation of the deformable zones sheath, are made up of means allowing to exercise an overpressure on the external face thereof.
Dans un autre mode de mise en oeuvre de l'invention les moyens aptes à assurer la déformation sont constitués de moyens permettant d'exercer une dépression sur la face interne du fourreau fermant les cavités.In another embodiment of the invention the means capable of ensuring the deformation consist of means for exerting a depression on the face internal sheath closing the cavities.
Dans une variante de l'invention les cavités sont constituées d'évidements réalisés sur la totalité de la périphérie de la surface externe de l'arbre, et les surfaces de maintien sont constituées de surfaces cylindriques de faible largeur. In a variant of the invention the cavities are made up of recesses made over the entire periphery of the outer surface of the tree, and the surfaces support are made up of cylindrical surfaces of narrow width.
Dans une autre variante de l'invention, chaque cavité est en communication avec un canal longitudinal prévu dans l'arbre, ce canal étant lui-même en communication avec des moyens d'aspiration, de façon à créer un vide contrôlé dans le volume délimité par chaque cavité et la surface interne en regard du fourreau.In another variant of the invention, each cavity is in communication with a longitudinal channel provided in the tree, this channel itself being in communication with suction means, so as to create a controlled vacuum in the volume delimited by each cavity and the internal surface in look of the scabbard.
La surface externe du fourreau peut également être creusée, en regard de chacune des surfaces de maintien, d'un évidement dont la profondeur est telle que, lorsque le fourreau est en position d'assemblage, la surface externe de celui-ci en regard de la surface de maintien est située sensiblement dans le prolongement de sa surface externe située en regard des cavités.The outer surface of the sheath can also be hollowed out, opposite each of the holding surfaces, with a recess whose depth is such that when the sleeve is in assembly position, the outer surface of this next to the holding surface is located substantially in line with its external surface located next to the cavities.
On décrira ci-après, à titre d'exemples non limitatifs,
diverses formes d'exécution de la présente invention, en
référence aux dessins annexés sur lesquels :
Sur la figure 1, le dispositif suivant l'invention est
constitué d'un arbre cylindrique 1 d'axe longitudinal xx' qui
est destiné à supporter et à entraíner un manchon anilox 3.
L'arbre 1 comporte, à chacune de ses extrémités, des poupées
5,5' destinées à assurer son maintien et son entraínement en
rotation. L'arbre 1 est creusé, sur sa périphérie, de
plusieurs cavités 7 de section annulaire, qui sont chacune en
communication, par un conduit radial 9, avec un canal
longitudinal 11 qui débouche à une extrémité de l'arbre 1,
ces cavités étant séparées par des surfaces de maintien 12
non creusées cylindriques. Un fourreau 2 de faible épaisseur
est emmanché sur les surfaces de maintien 12 de l'arbre 1. Ce
fourreau est réalisé en résine époxy armée de fibres de
verre. L'arbre 1 est creusé d'un second canal longitudinal 13
qui est axial et qui débouche également à une extrémité de
l'arbre 1. Le canal 13 est en communication avec cinq
conduits radiaux 15 qui débouchent sur la périphérie de
l'arbre 1, dans une cuvette cylindrique 17 de petite
dimension. Le fourreau 2 est percé, en face de chaque conduit
15, d'un orifice 18. De chaque côté de la cuvette 17, l'arbre
1 est creusé de deux rainures circulaires 19 dans lesquelles
sont disposés des joints toriques 21. Un autre joint torique
21' est disposé dans une rainure circulaire 19' à l'autre
extrémité de l'arbre 1.In FIG. 1, the device according to the invention is
consisting of a
Le manchon 3 est constitué notamment d'un métal, par exemple de l'aluminium. Il peut également être constitué de matériaux de synthèse mettant en oeuvre une structure notamment en nid d'abeilles, de façon à posséder une grande rigidité. The sleeve 3 consists in particular of a metal, by example of aluminum. It can also consist of synthetic materials using a structure especially honeycomb, so as to have a large rigidity.
Dans ces conditions, la mise en place du manchon 3 sur
l'arbre 1 et son démontage s'effectuent ainsi que décrit ci-après.Under these conditions, the installation of the sleeve 3 on
the
Comme représenté sur la figure schématique 3, après
avoir emmanché le fourreau 2 sur l'arbre 1, on introduit à
force le sous-ensemble ainsi constitué, à l'intérieur du
manchon 3, sur une longueur suffisante 1 pour que les
orifices 18 du fourreau 2 pénètrent à l'intérieur du manchon
3. On injecte ensuite par le canal axial 13 un flux d'air
sous pression A, de façon que celui-ci traverse le fourreau 2
par les orifices 18, et crée, entre la surface de la paroi
interne du manchon 3 et la surface de la paroi externe du
fourreau 2, un film d'air sous pression qui a pour effet de
repousser les parties du fourreau 2, qui se trouvent en vis-à-vis
des cavités 7, ou parties déformables 25, ce qui permet
d'introduire facilement ledit sous-ensemble à l'intérieur du
manchon 3.As shown in schematic figure 3, after
having put the
La déformation du fourreau 2 est facilitée par le fait
que les volumes V, compris entre les parois internes de
chaque cavité 7 et la face interne des parties déformables 25
du fourreau 2, sont maintenus à la pression atmosphérique par
les conduits 9 et le canal 11. En effet, l'air sous pression
injecté par les orifices 18 ne peut pénétrer dans ces volumes
V en raison de la présence des joints toriques 21 et 21'.The deformation of the
Lorsque ledit sous-ensemble est positionné à
l'intérieur du manchon 3, il suffit de supprimer le flux
d'air sous pression A pour que le fourreau 2 reprenne sa
forme initiale et que sa surface externe se trouve fortement
plaquée contre la paroi interne du manchon 3, ce qui assure
une bonne liaison de ces deux éléments.When said subset is positioned at
inside the sleeve 3, just remove the flow
of pressurized air A so that the
Comme représenté sur la figure 2, on peut réaliser, sur
la surface externe périphérique du fourreau 2, au droit des
surfaces de maintien 12, des évidements 27 d'une profondeur e
telle que, lorsque le fourreau 2 se trouve en position
d'assemblage, la surface externe de celui-ci en regard des
surfaces de maintien 12 est située sensiblement dans le
prolongement de sa surface externe située en regard des
cavités 7.As shown in FIG. 2, it is possible to make, on the peripheral external surface of the
Il est également possible, suivant la présente
invention, de réaliser la déformation du fourreau 2,
nécessaire à sa mise en position d'assemblage, en réalisant
un vide contrôlé dans les volumes V délimités par les parois
internes des cavités 7 et du fourreau 2.It is also possible, according to this
invention, to carry out the deformation of the
Ainsi, dans le mode de mise en oeuvre représenté sur la
figure 1, on peut, pour ce faire, relier l'orifice externe du
canal 11 à des moyens d'aspiration tels qu'une pompe à vide.Thus, in the embodiment shown in the
Figure 1, we can, to do this, connect the external orifice of the
La présente invention permet ainsi de réaliser un blocage amovible d'un manchon, et notamment d'un manchon anilox, sur son arbre d'entraínement, sans provoquer de déformation à la surface supérieure de ce manchon. Par ailleurs, ce dispositif permet d'assurer un tel blocage, sans qu'il soit nécessaire, en cours de fonctionnement, de mettre en oeuvre des moyens de maintien hydrauliques sous pression.The present invention thus makes it possible to produce a removable locking of a sleeve, and in particular of a sleeve anilox, on its drive shaft, without causing deformation on the upper surface of this sleeve. Through elsewhere, this device ensures such blocking, without that it is necessary, during operation, to put using hydraulic pressure maintenance means.
Un tel dispositif est ainsi particulièrement approprié pour assurer la fixation sur un arbre d'entraínement de manchons anilox rigides en aluminium revêtu de céramique, qui présentent l'avantage d'être faciles à réaliser mais qui ne peuvent être mis en oeuvre que sur des manchons ne subissant, en surface, strictement aucune déformation sous peine de réaliser une fissuration de la céramique.Such a device is thus particularly suitable to secure the attachment to a drive shaft of rigid aluminum anilox sleeves coated with ceramic, which have the advantage of being easy to carry out but which does not can be used only on sleeves which do not undergo, on the surface, strictly no deformation under penalty of crack the ceramic.
