Description

La présente invention concerne un manchon d'adaptation de format pour une presse rotative, du type comprenant une surface extérieure.The present invention relates to a format adapter sleeve for a rotary press, of the type comprising an outer surface.

Dans une presse rotative, la longueur circonférentielle de la plaque à imprimer est un paramètre déterminant la longueur d'impression du produit à imprimer. Afin d'augmenter la flexibilité de la presse, il est nécessaire de permettre une variation de longueur d'impression ou une variation de format.In a rotary press, the circumferential length of the printing plate is a parameter determining the print length of the product to be printed. In order to increase the flexibility of the press, it is necessary to allow a variation of printing length or a variation of format.

Afin de modifier la longueur circonférentielle d'un cylindre ayant un rayon fixe dans une presse, des manchons d'adaptation ouverts ayant différentes épaisseurs peuvent être montés sur un moyeu. Un tel manchon est par exemple divulgué dans la demande W02005/014286 de la Demanderesse.In order to change the circumferential length of a cylinder having a fixed radius in a press, open matching sleeves having different thicknesses may be mounted on a hub. Such a sleeve is for example disclosed in the application W02005 / 014286 of the Applicant.

Le document DE-A-10 2004 032645 montre un manchon d'adaptation de format conventionnel.The document DE-A-10 2004 032645 shows a conventional format adapter sleeve.

La réalisation d'un mécanisme de tension destiné à tendre un tel manchon ouvert autour d'un moyeu cylindrique est complexe du fait de la nécessité d'éviter que les bords de tête et de queue du manchon ne se soulèvent du moyeu sous l'effet de l'effort de tension.The realization of a tension mechanism intended to tension such an open sleeve around a cylindrical hub is complex because of the need to prevent the head and tail edges of the sleeve from being lifted from the hub under the effect the tension force.

Il est par ailleurs connu de dilater un manchon d'adaptation fermé par un coussin d'air afin de pouvoir le monter sur le moyeu de la presse. Toutefois, la dilatation d'un manchon fermé demande une pression très importante ou implique l'utilisation d'un manchon à la fois élastique et incompressible, ce qui sont des propriétés de matière généralement incompatible.It is also known to expand an adapter sleeve closed by an air cushion so as to mount it on the hub of the press. However, the expansion of a closed sleeve requires a very high pressure or involves the use of a sleeve both elastic and incompressible, which are properties of generally incompatible material.

C'est pourquoi l'invention a pour but de pallier les inconvénients cités et de fournir un manchon d'adaptation qui soit facile à monter sur le moyeu.This is why the invention aims to overcome the disadvantages mentioned and to provide an adapter sleeve that is easy to mount on the hub.

A cet effet, l'invention a pour objet un manchon d'adaptation du type indiqué, caractérisé en ce qu'à l'état non monté du manchon d'adaptation, la surface extérieure du manchon d'adaptation est tronconique.For this purpose, the subject of the invention is an adapter sleeve of the type indicated, characterized in that in the unmounted state of the adapter sleeve, the outer surface of the adapter sleeve is frustoconical.

  • la rainure axiale a une section transversale ayant une contre-dépouille dans le sens radial, notamment en forme de queue d'aronde ; et
  • la rainure axiale augmente de largeur circonférentielle d'une de ses extrémités axiales à l'autre extrémité axiale.

  • la conicité de la surface extérieure du moyeu et la conicité de la surface extérieure du manchon d'adaptation, à l'état non monté du manchon d'adaptation, sont identiques ;
  • le manchon d'adaptation et le moyeu définissent chacun une extrémité de grand diamètre et une extrémité de petit diamètre, à l'état monté du manchon d'adaptation sur le moyeu, l'extrémité de grand diamètre du manchon d'adaptation est dirigée vers l'extrémité de petit diamètre du moyeu, et, à l'état monté du manchon d'adaptation sur le moyeu, l'extrémité de petit diamètre du manchon d'adaptation est dirigée vers l'extrémité de grand diamètre du moyeu.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • la Figure 1 est une vue schématique en perspective d'un ensemble d'un manchon et d'un moyeu selon l'invention ;
  • la Figure 2A est une vue en coupe axiale de l'ensemble de la Figure 1 et d'une plaque d'impression ;
  • la Figure 2B est une vue axiale selon la direction IIB de la Figure 2A ;

  • la Figure 3B est une vue axiale selon la direction IIIB de la Figure 3A ; et
  • la Figure 4 est une vue analogue à celle de la Figure 2A, pendant le montage du manchon d'adaptation sur le moyeu.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
  • the Figure 1 is a schematic perspective view of an assembly of a sleeve and a hub according to the invention;
  • the Figure 2A is an axial sectional view of the whole of the Figure 1 and a printing plate;
  • the Figure 2B is an axial view along the IIB direction of the Figure 2A ;
  • the Figure 3A is an axial sectional view of an adapter sleeve according to the invention, in the unassembled state;
  • the Figure 3B is an axial view along the IIIB direction of the Figure 3A ; and
  • the Figure 4 is a view similar to that of the Figure 2A , during mounting of the adapter sleeve on the hub.

Sur la Figure 1 est représenté un ensemble selon l'invention, désigné par la référence générale 2.On the Figure 1 is represented an assembly according to the invention, designated by the general reference 2.

L'ensemble 2 comporte un moyeu 4 d'une presse rotative et un manchon d'adaptation 6.The assembly 2 comprises a hub 4 of a rotary press and an adapter sleeve 6.

Le moyeu 4 s'étend suivant un axe central X-X et est relié à des moyens d'entraînement en rotation non représentés, tel qu'un moteur électrique.The hub 4 extends along a central axis X-X and is connected to unrepresented rotary drive means, such as an electric motor.

Le moyeu 4 comporte une surface extérieure 8 qui a une forme tronconique de symétrie de rotation autour de l'axe X-X. Ainsi, le moyeu 4 forme une extrémité de petit diamètre 10 et une extrémité de grand diamètre 12. Comme indiqué sur la Figure 2A, une génératrice 14 de la surface extérieure 8 est inclinée d'un angle α par rapport à l'axe X-X. Cet angle α est par exemple compris entre 3 minutes et 1 degré.The hub 4 has an outer surface 8 which has a frustoconical shape of rotational symmetry about the axis XX. Thus, the hub 4 forms a small diameter end 10 and a large diameter end 12. As shown in FIG. Figure 2A a generatrix 14 of the outer surface 8 is inclined at an angle α with respect to the axis XX. This angle α is for example between 3 minutes and 1 degree.

Le manchon d'adaptation 6 est un manchon fermé sur tout son pourtour. Le manchon d'adaptation s'étend le long d'un axe central Y-Y, qui, à l'état monté coïncide avec l'axe X-X.The adapter sleeve 6 is a closed sleeve around its periphery. The adapter sleeve extends along a central axis Y-Y, which in the mounted state coincides with the X-X axis.

Le manchon d'adaptation 6 est réalisé en un matériau classique suffisamment élastique au moins dans sa direction circonférentielle, tel qu'un matériau plastique ou un matériau composite. La matière est par exemple de la fibre de verre imprégnée de résine.The adapter sleeve 6 is made of a conventional material sufficiently elastic at least in its circumferential direction, such as a plastic material or a composite material. The material is, for example, glass fiber impregnated with resin.

En variante, le manchon d'adaptation 6 est fabriqué en un matériau peu élastique, tel que du métal rendu expansible par une série de fentes traversantes parallèles à son axe. Dans ce cas, la raideur du manchon à l'extension est réglée par le nombre de fentes exécutées sur son pourtour. Ce même principe peut être appliqué à un matériau non métallique.In a variant, the adapter sleeve 6 is made of a material that is not very elastic, such as metal made expandable by a series of through slots parallel to its axis. In this case, the stiffness of the sleeve at the extension is regulated by the number of slots executed on its periphery. This same principle can be applied to a non-metallic material.

Comme ceci est visible sur la Figure 3A, le manchon d'adaptation 6 comporte une surface extérieure 16, ainsi qu'une surface intérieure 18. La surface extérieure 16 a, à l'état non monté du manchon 6 sur le moyeu 4, une forme tronconique centré sur l'axe central Y-Y du manchon d'adaptation 6. La surface intérieure 18 est, à l'état non monté du manchon d'adaptation 6, cylindrique à section circulaire autour de l'axe central Y-Y.As this is visible on the Figure 3A , the adapter sleeve 6 has an outer surface 16 and an inner surface 18. The outer surface 16 has, in the unmounted state of the sleeve 6 on the hub 4, a frustoconical shape centered on the central axis YY of the adapter sleeve 6. The inner surface 18 is, in the unmounted state of the adapter sleeve 6, cylindrical with a circular section around the central axis YY.

La génératrice 20 de la surface extérieure 16 est inclinée par rapport à l'axe central Y-Y d'un angle β. La valeur de cet angle β est identique à l'angle α, mais le sens d'inclinaison est l'inverse de celui de l'angle α.The generatrix 20 of the outer surface 16 is inclined relative to the central axis Y-Y of an angle β. The value of this angle β is identical to the angle α, but the direction of inclination is the inverse of that of the angle α.

Ainsi, le manchon 6 définit à l'état non monté une extrémité de petit diamètre extérieur 22 et une extrémité de grand diamètre extérieur 24.Thus, the sleeve 6 defines in the unassembled state a small outer diameter end 22 and a large outer diameter end 24.

Par ailleurs, le manchon d'adaptation 6 comporte une rainure axiale 26 dans sa surface extérieure 16. Cette rainure 26 est adaptée pour recevoir les bords de tête 28 et de queue 30 d'une plaque d'impression 32. Comme ceci est visible sur la Figure 1 et la Figure 2A en section transversale, la rainure axiale 26 a une forme ayant une contre-dépouille dans le sens radial, et est dans le cas présent en forme de queue d'aronde, la partie élargie étant dirigée vers l'axe central Y-Y.Furthermore, the adapter sleeve 6 has an axial groove 26 in its outer surface 16. This groove 26 is adapted to receive the leading edges 28 and tail 30 of a printing plate 32. As can be seen on the Figure 1 and the Figure 2A in cross-section, the axial groove 26 has a shape with an undercut in the radial direction, and is in this case dovetail-shaped, the widened portion being directed towards the central axis YY.

Dans l'exemple représenté, la rainure axiale 26 a une section transversale identique sur toute sa longueur axiale, mais en variante, la rainure axiale 26 a une largeur qui augmente d'une de ses extrémités axiales à l'autre, afin de faciliter l'enfichage des bords 28, 30 de la plaque d'impression 32 dans la rainure 26.In the example shown, the axial groove 26 has an identical cross section over its entire axial length, but alternatively, the axial groove 26 has a width which increases from one of its axial ends to the other, in order to facilitate the inserting the edges 28, 30 of the printing plate 32 into the groove 26.

Par ailleurs, le manchon d'adaptation 6 comporte un moyen de localisation angulaire qui permet d'aligner angulairement le manchon d'adaptation 6 au moyeu 4. Ce moyen de localisation comprend un évidement 34 qui est ouvert vers l'axe Y-Y et vers l'extrémité 22 et qui est disposé à cette extrémité 22.Moreover, the adapter sleeve 6 comprises an angular localization means which makes it possible to angularly align the adapter sleeve 6 with the hub 4. This locating means comprises a recess 34 which is open towards the axis YY and towards the end 22 and which is disposed at this end 22.

Sur la figure 2A est représenté le moyeu 4, le manchon 6 et la plaque d'impression 32 à l'état monté.On the Figure 2A is represented the hub 4, the sleeve 6 and the printing plate 32 in the mounted state.

Le manchon d'adaptation 6 est élastiquement déformé par le moyeu 4, de telle sorte que la surface intérieure 18 du manchon d'adaptation 6 a une conicité qui est identique à celle de la surface extérieure 8 du moyeu 4. La surface extérieure 16 du manchon d'adaptation 6 est cylindrique à section circulaire autour de l'axe central X-X.The adapter sleeve 6 is elastically deformed by the hub 4, so that the inner surface 18 of the adapter sleeve 6 has a conicity which is identical to that of the outer surface 8 of the hub 4. The outer surface 16 of the adapter sleeve 6 is cylindrical with a circular section around the central axis XX.

L'extrémité axiale 24 de grand diamètre du manchon d'adaptation 6 est dirigée vers l'extrémité axiale de petit diamètre 10 du moyeu 4 et l'extrémité de petit diamètre 22 du manchon d'adaptation 6 est dirigée vers l'extrémité de grand diamètre 12 du moyeu 4. Ainsi, le moyeu 4 déforme le manchon d'adaptation 6 de telle manière que la surface extérieure 16 du manchon prenne sa forme cylindrique.The axial end 24 of large diameter of the adapter sleeve 6 is directed towards the small diameter axial end 10 of the hub 4 and the small diameter end 22 of the adapter sleeve 6 is directed towards the large end. Thus, the hub 4 deforms the adapter sleeve 6 so that the outer surface 16 of the sleeve takes on its cylindrical shape.

Le procédé de montage du manchon d'adaptation 6 sur le moyeu 4 sera expliqué par la suite.The method of mounting the adapter sleeve 6 on the hub 4 will be explained later.

Initialement, le manchon d'adaptation 6 est à l'état non monté, tel que montré sur les figures 3A et 3B.Initially, the adapter sleeve 6 is in the unassembled state, as shown on the Figures 3A and 3B .

Tout d'abord, l'extrémité de petit diamètre 22 du manchon 6 est alignée avec l'extrémité de petit diamètre 10 du moyeu 4. Ensuite, la plaque d'impression 32 est enfilée sur le manchon d'adaptation 6. Puis l'ensemble du manchon d'adaptation 6 et de la plaque d'impression 32 est axialement enfilé sur le moyeu 4. L'effort axial nécessaire dépend de la conicité du moyeu 4, de la raideur du manchon 6, du coefficient de frottement entre les deux surfaces extérieure 8 et intérieure 18. Plus la conicité de la surface extérieure 8 est faible, plus le montage est facile.First, the small diameter end 22 of the sleeve 6 is aligned with the small diameter end 10 of the hub 4. Then, the printing plate 32 is threaded onto the adapter sleeve 6. Then the all of the adapter sleeve 6 and the printing plate 32 is axially threaded onto the hub 4. The axial force required depends on the conicity of the hub 4, the stiffness of the sleeve 6, the coefficient of friction between the two external surfaces 8 and inner 18. The smaller the conicity of the outer surface 8, the easier the mounting.

Le manchon d'adaptation 6 est enfilé sur le moyeu 4 jusqu'à ce que la totalité de sa surface intérieure 18 soit en contact avec la surface extérieure 8 du moyeu 4. Ainsi, la surface extérieure du manchon 6 devient cylindrique. En poursuivant l'enfoncement du manchon 6 sur le moyeu 8, son diamètre extérieur augmente. Ceci tend la plaque d'impression.The adapter sleeve 6 is threaded onto the hub 4 until all of its inner surface 18 is in contact with the outer surface 8 of the hub 4. Thus, the outer surface of the sleeve 6 becomes cylindrical. By continuing the depression of the sleeve 6 on the hub 8, its outer diameter increases. This tends the printing plate.

L'effort axial nécessaire à l'emmanchement et à l'extraction du manchon d'adaptation 6 peut être obtenu par un mécanisme non représenté disposé sur le moyeu 4, ou, en variante, par un mécanisme disposé sur la presse rotative. Un tel dispositif peut être par exemple constitué d'un système vis et écrou axial agissant sur un flasque rendu solidaire du manchon 6.The axial force required for the fitting and extraction of the adapter sleeve 6 can be obtained by a mechanism not shown disposed on the hub 4, or, alternatively, by a mechanism disposed on the rotary press. Such a device may consist for example of an axial screw and nut system acting on a flange secured to the sleeve 6.

En variante encore, le moyeu d'adaptation 6 et le moyeu 4 peuvent être des cylindres porte-blanchet.In another variant, the adapter hub 6 and the hub 4 may be blanket cylinders.
