Description

L'invention se rapporte à un dispositif de fixation d'une plaque sur un cylindre tout en permettant de commander rapidement, à certains moments, l'application et la fixation de la dite plaque sur une portion angulaire déterminée de ce cylindre et, à d'autres moments, le dégagement de cette plaque.The invention relates to a device for fixing a plate to a cylinder while allowing rapid control, at certain times, of the application and fixing of said plate on a determined angular portion of this cylinder and, d 'other times, the release of this plaque.

Elle se rapporte également à la machine comprenant au moins un cylindre pourvu d'au moins un tel dispositif.It also relates to the machine comprising at least one cylinder provided with at least one such device.

Elle s'applique plus particulièrement, mais non exclusivement, aux machines rotatives d'impression et de découpage sur les cylindres desquelles machines, il est en effet nécessaire que l'outil, tel un cliché, ou la contrepartie d'impression ou de découpe, puisse, lors du travail, être fixé et appliqué parfaitement sur le cylindre mais aussi, entretemps, être dégagé rapidement de la zone du cylindre où il appuie, ne serait-ce que pour libérer l'accés à cette zone, le temps nécessaire pour y glisser des cales susceptibles de pallier certains défauts de l'outil ou de la contrepartie.It applies more particularly, but not exclusively, to rotary printing and cutting machines on the cylinders of which machines, it is indeed necessary that the tool, such as a plate, or the printing or cutting counterpart, can, during work, be fixed and applied perfectly on the cylinder but also, in the meantime, be quickly released from the area of the cylinder where it presses, if only to free access to this area, the time necessary to slip wedges capable of overcoming certain faults in the tool or the counterpart.

Avec les dispositifs connus à ce jour, la plaque est maintenue sur le cylindre par des moyens mécaniques de tension, tels des brides saisissant les extrémités de la plaque ou par des moyens magnétiques.With the devices known to date, the plate is held on the cylinder by mechanical tensioning means, such as flanges gripping the ends of the plate or by magnetic means.

Outre que cette action sur les extrémités de la plaque tend à bomber la plaque et quoiqu'il en soit, ne garantit pas une application parfaite de sa partie médiane, on déplore surtout que pour libérer l'accés sous la plaque, il soit nécessaire de démonter le bridage, ce qui est très long ; puis de porter en un autre lieu la plaque dont le poids peut être très important.Besides that this action on the ends of the plate tends bending the plate and anyway, does not guarantee a perfect application of its middle part, we especially deplore that to free access under the plate, it is necessary to dismantle the clamping, which is very long; then take the plate, the weight of which can be very significant, to another place.

Un résultat que l'invention vise à obtenir est un tel dispositif qui assure tant une application parfaite de la plaque sur le cylindre qu'un effacement rapide de la plaque en vue de libérer le cylindre.One result which the invention aims to obtain is such a device which ensures both perfect application of the plate on the cylinder and rapid erasure of the plate in order to release the cylinder.

A cet effet, elle a pour objet un dispositif du type cité plus haut, notamment caractérisé en ce que, en plus de moyens permettant d'amener la plaque contre le cylindre ou au contraire de l'écarter de sa zone d'appui, il comprend des moyens d'application parfaite aussi bien de la partie médiane que des extrémités de la plaque sur le cylindre. L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé, qui représente schématiquement :

  • - figure 1 : le cylindre et le dispositif vus en perspective,
  • - figure 2 : le cylindre et le dispositif vus de profil et à plus grande échelle.
To this end, it relates to a device of the type mentioned above, in particular characterized in that, in addition to means making it possible to bring the plate against the cylinder or on the contrary to move it away from its bearing zone, it includes means for perfect application of both the middle part and the ends of the plate on the cylinder. The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing, which schematically represents:
  • - Figure 1: the cylinder and the device seen in perspective,
  • - Figure 2: the cylinder and the device seen in profile and on a larger scale.

En se reportant au dessin, on voit que la machine comprend un cylindre 1 sur une portion angulaire "A" de la surface latérale 2 duquel, pendant le travail, doit être parfaitement appliquée et énergiquement fixée une plaque 3 telle un cliché.Referring to the drawing, it can be seen that the machine comprises a cylinder 1 on an angular portion "A" of the lateral surface 2 from which, during work, must be perfectly applied and energetically fixed a plate 3 such as a plate.

Ce cylindre 1 est pourvu de deux tourillons ou fusées 4 par lesquelles il est guidé et entraîné en rotation autour de son axe 5 par tout moyen connu (non représenté).This cylinder 1 is provided with two journals or rockets 4 by which it is guided and driven in rotation around its axis 5 by any known means (not shown).

Il coopère avec une forme 6 portée par un autre cylindre ou un marbre 7.It cooperates with a shape 6 carried by another cylinder or a plate 7.

Les plaques étant rarement parfaites, et le plus petit défaut d'épaisseur dans la plaque se traduisant par un défaut dans le travail fourni, des retouches doivent fréquemment être réalisées et, à cet effet, il faut pouvoir placer des câles 8 sous la plaque en les fixant directement sur la face 2 du cylindre 1 ou sur une feuille intermédiaire.The plates are rarely perfect, and the smallest defect in thickness in the plate resulting in a defect in the work provided, touch-ups must frequently be carried out and, for this purpose, it is necessary to be able to place shims 8 under the plate in fixing them directly on the face 2 of the cylinder 1 or on an intermediate sheet.

Selon une caractéristique essentielle de l'invention, en plus des moyens 9 d'amenée et d'effacement de la plaque 3, le dispositif de fixation de la plaque comprend des moyens 10 d'application parfaite aussi bien de la partie médiane que des extrémités de la plaque, sur le cylindre 1.According to an essential characteristic of the invention, in addition to the means 9 for supplying and erasing the plate 3, the device for fixing the plate comprises means 10 for perfect application of both the middle part and the ends of the plate, on cylinder 1.

Ces moyens 10 d'application comprennent, à l'intérieur de la surface d'appui de la plaque sur le cylindre, d'une part, tout au long des bords de cette surface, une gorge 11 logeant un joint d'étanchéité 12 et, d'autre part, à faible distance de ce joint, des orifices 13 raccordées à un circuit 14 d'aspiration d'une pompe à vide 15.These application means 10 comprise, inside the bearing surface of the plate on the cylinder, on the one hand, all along the edges of this surface, a groove 11 housing a seal 12 and , on the other hand, at a short distance from this joint, orifices 13 connected to a circuit 14 for suction of a vacuum pump 15.

La différence de pression entre la face interne de la plaque soumise à l'action de la pompe et sa face externe soumise à la pression atmosphérique applique énergiquement la plaque sur le cylindre.The pressure difference between the internal face of the plate subjected to the action of the pump and its external face subjected to atmospheric pressure energetically applies the plate to the cylinder.

Pour une meilleure répartition de l'action de la dépression, de préférence, les orifices 13 débouchent dans une gorge périphérique 16.For a better distribution of the action of the depression, preferably, the orifices 13 open into a peripheral groove 16.

Afin d'éviter une entrée intempestive d'air après arrêt de la pompe, ne serait-ce que consécutivement à une coupure de courant, un clapet anti-retour 17 est placé sur le circuit 14.In order to avoid an untimely entry of air after stopping the pump, even if only after a power cut, a non-return valve 17 is placed on the circuit 14.

Les gorges 11, 16 peuvent être toutes deux portées par la plaque ou réparties l'une sur la plaque, l'autre sur le cylindre mais, de préférence, elles sont portées par le cylindre 1, lequel est creux et, de ce fait, intercalée entre les orifices 13 et le circuit 14, la cavité 18 du cylindre 1 peut être utilisée comme une chambre de réserve, notamment dans l'hypothèse évoquée plus haut d'un arrêt de la pompe à vide 15.The grooves 11, 16 can both be carried by the plate or distributed one on the plate, the other on the cylinder but, preferably, they are carried by the cylinder 1, which is hollow and, therefore, interposed between the orifices 13 and the circuit 14, the cavity 18 of the cylinder 1 can be used as a reserve chamber, in particular in the hypothesis mentioned above of stopping the vacuum pump 15.

Pour ce faire, les orifices 13 débouchent dans la cavité 18 à laquelle le circuit 14 est relié par l'intermédiaire d'un joint tournant 19.To do this, the orifices 13 open into the cavity 18 to which the circuit 14 is connected by means of a rotary joint 19.

Entre le clapet anti-retour 17 et la chambre 18, le circuit 14 est relié à un distributeur 20 permettant, en vue d'un effacement de la plaque, de porter la chambre 18 à la pression atmosphérique.Between the non-return valve 17 and the chamber 18, the circuit 14 is connected to a distributor 20 allowing, with a view to erasing the plate, to bring the chamber 18 to the atmospheric pressure.

Afin que l'action de la pompe à vide 15 produise l'application parfaite de la plaque 3 sur le cylindre 1 il est bien sûr nécessaire que, dans un premier temps, la plaque 3 soit amenée suffisamment près du cylindre pour que le joint d'étanchéité 12 permette d'isoler de la pression atmosphérique, le volume situé sous la plaque 3.In order for the action of the vacuum pump 15 to produce the perfect application of the plate 3 on the cylinder 1 it is of course necessary that, firstly, the plate 3 is brought close enough to the cylinder so that the seal d seal 12 allows the volume located under the plate 3 to be isolated from atmospheric pressure.

Ce moyen d'amener la plaque 3 contre le cylindre 1 pourrait consister en un dispositif classique de fixation de la plaque mais dans un mode préféré de réalisation et selon une caractéristique essentielle de l'invention, ce moyen 9 comprend deux moyeux 21 engagés chacun sur l'une des fusées 4 du cylindre 1 autour de l'axe 5 duquel ces moyeux 21 sont libres d'osciller au moins d'un certain angle et, à chacun de ces moyeux 21, est, par au moins un bras 22 de longueur réglable, associée à un support tel une bride 23 apte à saisir par tout moyen connu une extrémité de la plaque 3. Du côté opposé aux supports 23, les moyeux 21 portent avantageusement des contre-poids 24 qui, lorsque la plaque est, par élongation des bras 3, écartée du cylindre 1, équilibrent la charge de l'ensemble que forment les bras les supports et la dite plaque 3.This means of bringing the plate 3 against the cylinder 1 could consist of a conventional device for fixing the plate, but in a preferred embodiment and according to an essential characteristic of the invention, this means 9 comprises two hubs 21 each engaged on one of the rockets 4 of the cylinder 1 around the axis 5 from which these hubs 21 are free to oscillate at least by a certain angle and, at each of these hubs 21, is, by at least one arm 22 of length adjustable, associated with a support such as a flange 23 capable of grasping by any known means one end of the plate 3. On the side opposite the supports 23, the hubs 21 advantageously carry counterweights 24 which, when the plate is, by elongation arms 3, separated from cylinder 1, balance the load of the assembly formed by the arms, the supports and said plate 3.

De ce fait, lorsque la plaque sera ainsi écartée, ce sera sans aucun effort qu'à la main ou à l'aide d'une commande mécanique, cet ensemble pourra osciller autour de l'axe 5 du cylindre 1 et permettra ainsi de chasser la plaque 3 de sa zone d'appui sur le cylindre 1 par exemple, pour y effectuer des opérations de retouche.Therefore, when the plate is thus spread, it will be without any effort that by hand or with the aid of a mechanical control, this assembly will be able to oscillate around the axis 5 of the cylinder 1 and will thus make it possible to drive out the plate 3 of its bearing area on the cylinder 1 for example, to perform touch-up operations there.

Dans un mode préféré de réalisation, les bras réglables 22 consistent en des vérins alimentés en fluide sous pression par un circuit 25 contrôlé par un distributeur 26.In a preferred embodiment, the adjustable arms 22 consist of jacks supplied with pressurized fluid by a circuit 25 controlled by a distributor 26.

Selon une caractéristique de l'invention, chaque bras 22, constitué par un vérin, à simple ou à double effet, est pourvu d'un élément élastique 27, tel un ressort, sollicitant en permanence le support et donc la plaque vers le cylindre 1,grâce à quoi, même en cas de rupture de l'alimentation en fluide des vérins 22, la plaque sera appliquée sur le cylindre et la machine pourra être utilisée, le fluide n'étant alors indispensable que pour écarter la plaque.According to a characteristic of the invention, each arm 22, consisting of a cylinder, single or double acting, is provided with an elastic element 27, such as a spring, permanently urging the support and therefore the plate towards the cylinder 1 , whereby, even in the event of a break in the fluid supply to the jacks 22, the plate will be applied to the cylinder and the machine can be used, the fluid then being essential only for spreading the plate.

Selon une autre caractéristique de l'invention, le distributeur 26 placé sur le circuit 25 de commande des bras réglables 22 et le distributeur 20 relié au circuit 14 de la pompe à vide sont associés par des moyens tels un même levier 28 assurant la concomitance :

  • - tant de la mise à la pression atmosphérique du dessous de la plaque 3 et de la mise en pression des vérins d'écartement de cette plaque,
  • - que de l'expulsion du fluide de commande des vérins d'écartement de la plaque que l'élément élastique ramènera sur le cylindre et de la dépression du dessous de la plaque.
According to another characteristic of the invention, the distributor 26 placed on the circuit 25 for controlling the adjustable arms 22 and the distributor 20 connected to the circuit 14 of the vacuum pump are associated by means such as the same lever 28 ensuring the concomitance:
  • - both the pressurization of the underside of the plate 3 at atmospheric pressure and the pressurization of the spacers of this plate,
  • - that of the expulsion of the fluid controlling the spacers of the plate that the elastic element will bring back onto the cylinder and of the vacuum from below the plate.
