Description

La présente invention concerne un ensemble pour presse rotative, du type comprenant

  • un moyeu adapté pour être monté en rotation autour d'un axe central dans une presse rotative et présentant une surface extérieure,
  • un manchon d'adaptation de format destiné à être monté sur le moyeu et comprenant une surface intérieure adaptée pour s'appliquer sur la surface extérieure du moyeu,
  • des moyens de fixation du manchon d'adaptation au moyeu.
The present invention relates to an assembly for a rotary press, of the type comprising
  • a hub adapted to be rotatably mounted about a central axis in a rotary press and having an outer surface,
  • a size adapter sleeve for mounting on the hub and having an inner surface adapted to be applied to the outer surface of the hub,
  • means for fixing the adapter sleeve to the hub.

Dans une presse rotative, la longueur circonférentielle de la plaque à imprimer est un paramètre limitant le format ou 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 plate to be printed is a parameter limiting the format or the printing 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 WO2005/014286 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 WO2005 / 014286 of the Applicant.

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 ensemble comprenant un manchon d'adaptation et un moyeu, le manchon étant facile à monter sur le moyeu.This is why the invention aims to overcome the drawbacks mentioned and to provide an assembly comprising an adapter sleeve and a hub, the sleeve being easy to mount on the hub.

A cet effet, l'invention a pour objet un ensemble pour presse rotative, caractérisé en ce que le moyeu et le manchon d'adaptation comportent chacun une surface de butée, limitant le déplacement axial du manchon d'adaptation sur le moyeu, en ce que les surfaces de butée ont une forme tronconique autour de l'axe central, et en ce que les moyens de fixation comprennent un organe de calage radial adapté pour être intercalé entre le moyeu et le manchon d'adaptation.For this purpose, the subject of the invention is an assembly for a rotary press, characterized in that the hub and the adapter sleeve each comprise an abutment surface, limiting the axial displacement of the adapter sleeve on the hub, in that that the stop surfaces have a frustoconical shape around the central axis, and in that the fixing means comprise a radial wedging member adapted to be interposed between the hub and the adapter sleeve.

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 axial section of an assembly of an adapter sleeve and a hub according to the invention;

  • the Figure 3 is a perspective view of the other end of the adapter sleeve without the hub;
  • the Figure 4 is a perspective view of one end of the hub corresponding to the end shown in FIG. Figure 3 ; and
  • the Figure 5 is a perspective view of an end of a variant of an assembly according to the invention.

Sur la Figure 1 est représenté un ensemble pour presse rotative, désigné par la référence générale 2.On the Figure 1 there is shown an assembly for a rotary press, designated by the general reference 2.

L'ensemble 2 comporte un moyeu 4 et un manchon d'adaptation de format 6 fermé sur son pourtour. L'ensemble 2 comporte en outre des moyens de fixation 8 du manchon d'adaptation 6 au moyeu 4.The assembly 2 comprises a hub 4 and a format matching sleeve 6 closed around its periphery. All 2 further comprises fastening means 8 of the adapter sleeve 6 to the hub 4.

Le moyeu 4 et le manchon d'adaptation 6 s'étendent selon un axe central commun X-X. Le moyeu 4 et le manchon d'adaptation 6 sont adaptés pour être montés en rotation autour de cet axe central X-X dans une presse rotative non représentée. A cet effet, le moyeu 4 comporte une extrémité commande 10, reliée à des moyens d'entraînement, tel qu'un moteur électrique, ainsi qu'une extrémité fonction 12.The hub 4 and the adapter sleeve 6 extend along a common central axis X-X. The hub 4 and the adapter sleeve 6 are adapted to be rotatably mounted around this central axis X-X in a rotary press, not shown. For this purpose, the hub 4 comprises a control end 10, connected to drive means, such as an electric motor, as well as a function end 12.

Le moyeu 4 comporte une surface extérieure centrale 14, qui a une forme cylindrique à section circulaire centrée sur l'axe central X-X. Il comporte en outre une surface de butée 16, se raccordant à la surface extérieure centrale 14 côté extrémité commande. La surface de butée 16 a une forme tronconique d'axe X-X s'évasant vers l'extrémité commande 10. Le moyeu 4 comporte en outre une surface de portée 18, qui se raccorde à la surface extérieure cylindrique centrale 14, côté extrémité fonction 12. Cette surface de portée 18 a une forme tronconique d'axe X-X se rétrécissant vers l'extrémité fonction 12.The hub 4 has a central outer surface 14, which has a cylindrical shape with a circular section centered on the central axis X-X. It further comprises an abutment surface 16, connecting to the central outer surface 14 end-control side. The abutment surface 16 has a frustoconical shape of axis XX flaring towards the control end 10. The hub 4 further comprises a bearing surface 18, which is connected to the central cylindrical outer surface 14, end end 12 This bearing surface 18 has a frustoconical shape of axis XX narrowing towards the function end 12.

Il est à noter que la surface de butée 16 et la surface de portée 18 se raccordent chacune d'une manière non étagée à la surface extérieure centrale 14 cylindrique. En d'autres termes, les diamètres des surfaces de butée 16 et de portée 18, à leur extrémité tournée vers la surface extérieure centrale 14 sont identiques au diamètre de la surface 14.It should be noted that the abutment surface 16 and the bearing surface 18 are each connected in a non-stepped manner to the cylindrical central outer surface 14. In other words, the diameters of abutment surfaces 16 and bearing surface 18 at their end facing the central outer surface 14 are identical to the diameter of surface 14.

Comme ceci est illustré sur la Figure 2, le moyeu 4 comporte en outre trois surfaces de fixation 20. Ces surfaces de fixation 20 sont plates et s'étendent d'une manière adjacente à la surface de butée 18. Les trois surfaces de fixation 20 sont régulièrement réparties autour de l'axe central X-X.As this is illustrated on the Figure 2 the hub 4 further comprises three fastening surfaces 20. These fastening surfaces 20 are flat and extend adjacent to the abutment surface 18. The three fastening surfaces 20 are regularly distributed around the axis central XX.

Comme visible sur les Figues 1 et 3, le manchon d'adaptation 6 comporte une surface extérieure cylindrique 22, qui reçoit à l'état monté une plaque d'impression ou un blanchet élastique non représentés. Le manchon d'adaptation 6 comporte en outre une surface intérieure centrale 24 cylindrique à section circulaire d'axe X-X, qui a le même diamètre que la surface extérieure 14 au jeu près qui est nécessaire pour pouvoir enficher le manchon d'adaptation 6 sur la surface extérieure 14 du moyeu 4 sans le dilater. La surface intérieure centrale 24 a la même longueur axiale que la surface extérieure centrale 14. Ainsi, la surface intérieure 24 est adaptée pour s'appliquer sur la surface extérieure 14 du moyeu 4.As shown in Figs 1 and 3, the adapter sleeve 6 has a cylindrical outer surface 22, which receives in the mounted state a printing plate or an elastic blanket not shown. The adapter sleeve 6 further comprises a central cylindrical inner surface 24 with a circular cross section of axis XX, which has the same diameter as the outer surface 14 with the clearance that is necessary to be able to plug the adapter sleeve 6 onto the outer surface 14 of the hub 4 without expanding it. The central inner surface 24 has the same axial length as the central outer surface 14. Thus, the inner surface 24 is adapted to bear on the outer surface 14 of the hub 4.

Le manchon d'adaptation 6 est muni en outre d'une surface de butée 26, qui se raccorde à la surface intérieure 24 du côté extrémité commande 10 et qui a une forme tronconique d'axe X-X s'évasant vers l'extrémité commande 10. Les deux surfaces de butée 16, 26 limitent le déplacement axial du manchon d'adaptation 6 sur le moyeu 4, dans le sens dirigé vers l'extrémité commande 10. Les génératrices des deux surfaces de butée 16 et 26 sont par exemple inclinées par rapport à l'axe X-X d'une valeur allant de 1° à 3°. Les surfaces de butée 16 et 26 sont complémentaires.The adapter sleeve 6 is further provided with an abutment surface 26, which is connected to the inner surface 24 of the control end side 10 and which has a frustoconical shape of axis XX flaring towards the control end 10 The two abutment surfaces 16, 26 limit the axial displacement of the adapter sleeve 6 on the hub 4, in the direction directed towards the control end 10. The generatrices of the two abutment surfaces 16 and 26 are, for example, inclined by ratio to the axis XX of a value ranging from 1 ° to 3 °. The abutment surfaces 16 and 26 are complementary.

La faible conicité de ces surfaces de butée 16,26 conduit à une fixation en rotation du manchon d'adaptation 6 sur le moyeu 4 par application de la surface de butée 26 sur la surface de butée 16.The low conicity of these abutment surfaces 16, 26 leads to a rotational fastening of the adapter sleeve 6 to the hub 4 by application of the abutment surface 26 to the abutment surface 16.

Le manchon d'adaptation 6 comporte en outre une surface de portée intérieure 28. Cette surface de portée 28 est cylindrique à section circulaire autour de l'axe central X-X et s'étend en vis-à-vis de la surface de portée 18 du moyeu 4 en laissant un interstice annulaire 30 qui est ouvert vers l'extrémité fonction 12. La surface de portée intérieure 28 a un diamètre qui est supérieur au diamètre de la surface intérieure centrale 24 cylindrique, de telle sorte que ces deux surfaces 24, 28 sont séparées par une partie étagée.The adapter sleeve 6 further comprises an inner bearing surface 28. This bearing surface 28 is cylindrical with a circular section around the central axis XX and extends opposite the bearing surface 18 of the hub 4 leaving an annular gap 30 which is open towards the end function 12. The bearing surface Inner 28 has a diameter which is greater than the diameter of the central cylindrical inner surface 24, so that these two surfaces 24, 28 are separated by a stepped portion.

Les moyens de fixation 8 du manchon d'adaptation 6 au moyeu 4 comprennent un organe de calage radial, qui est dans l'exemple présent constitué par un anneau de frette 32 fermé et élastiquement déformable. L'anneau de frette 32 comporte une surface extérieure cylindrique 34 ayant sensiblement le même diamètre que la surface de portée intérieure 28, ainsi qu'une surface intérieure conique 36 ayant une forme tronconique complémentaire de la forme de la surface de portée 18 du moyeu 4.The attachment means 8 of the adapter sleeve 6 to the hub 4 comprise a radial wedging member, which is in the present example constituted by a ring ring 32 closed and elastically deformable. The hoop ring 32 has a cylindrical outer surface 34 having substantially the same diameter as the inner bearing surface 28, and a conical inner surface 36 having a frustoconical shape complementary to the shape of the bearing surface 18 of the hub 4 .

Les moyens de fixation 8 comportent en outre trois blocs de fixation 38 dont chacun est fixé sur une des surfaces de fixation 20. Ce bloc de fixation 38 comporte un taraudage s'étendant parallèlement à l'axe central X-X, comme ceci est représenté à la Figure 2. Dans ce taraudage est vissé une vis de poussée 40, qui est adaptée pour pousser axialement l'organe de calage 32 vers l'extrémité de commande 10.The fixing means 8 further comprise three fixing blocks 38 each of which is fixed on one of the fastening surfaces 20. This fixing block 38 has a tapping extending parallel to the central axis XX, as shown in FIG. Figure 2 . In this tapping is screwed a thrust screw 40, which is adapted to axially push the clamping member 32 towards the control end 10.

En outre, le bloc de fixation 36 comporte une lumière 42 traversante s'étendant parallèlement à l'axe X-X, et se trouvant en vis-à-vis d'un taraudage non représenté ménagé dans l'organe de calage 32.In addition, the fixing block 36 has a through-hole 42 extending parallel to the X-X axis and facing a tapping (not shown) formed in the wedging member 32.

Cette lumière 42, le taraudage est une vis d'extraction non représentée forment des moyens d'extraction de l'organe de calage 32 hors de l'interstice 30.This light 42, the tapping is a not shown extraction screw form extraction means of the wedging member 32 out of the gap 30.

L'ensemble 2 comporte en outre des moyens d'indexation 50, adaptés pour fixer le manchon d'adaptation 6 sur le moyeu 4 dans une position circonférentielle définie. Ces moyens d'indexation 50 comprennent d'une part une encoche 52 ménagée dans le moyeu 4, en l'occurrence ménagée dans la surface de portée 16 (voir Figure 4), ainsi qu'une clavette d'indexation 54, qui est fixée par deux vis 56 dans un évidement correspondant 58 du manchon d'adaptation 6. La clavette d'indexation 54 et l'encoche 52 ont des formes complémentaires.The assembly 2 further comprises indexing means 50, adapted to fix the adapter sleeve 6 on the hub 4 in a defined circumferential position. These indexing means 50 comprise on the one hand a notch 52 formed in the hub 4, in this case formed in the bearing surface 16 (see Figure 4 ), so that an indexing key 54, which is fixed by two screws 56 in a corresponding recess 58 of the adapter sleeve 6. The indexing key 54 and the notch 52 have complementary shapes.

Comme ceci ressort particulièrement des Figures 2 et 3, le manchon d'adaptation 6 porte un dispositif de fixation 60 d'une plaque sur le manchon d'adaptation 6. Ce dispositif de fixation 60 comporte un vérin 62 qui est relié par un levier 64 à un dispositif de serrage 66 d'une plaque d'impression non représentée.As this is particularly apparent Figures 2 and 3 , the adapter sleeve 6 carries a device 60 for fixing a plate on the adapter sleeve 6. This fixing device 60 comprises a jack 62 which is connected by a lever 64 to a clamping device 66 of a printing plate not shown.

Le montage du manchon d'adaptation 6 sur le moyeu 4 est effectué de la manière suivante.The mounting of the adapter sleeve 6 on the hub 4 is performed as follows.

Tout d'abord, le manchon d'adaptation 6 est axialement aligné avec le moyeu 4. Ensuite, le manchon d'adaptation 6 est enfilé sur le moyeu 4 en déplaçant le manchon d'adaptation 6 vers l'extrémité commande 10 du moyeu 4, jusqu'à ce que les deux surfaces de butées 16, 26 entrent en contact.First, the adapter sleeve 6 is axially aligned with the hub 4. Then, the adapter sleeve 6 is threaded onto the hub 4 by moving the adapter sleeve 6 towards the control end 10 of the hub 4 , until the two abutment surfaces 16, 26 come into contact.

Ensuite, l'évidement 58 est circonférentiellement aligné avec l'encoche 52 et la clavette d'indexation 54 est vissée dans l'évidement 58.Then, the recess 58 is circumferentially aligned with the notch 52 and the indexing key 54 is screwed into the recess 58.

Puis l'organe de calage 32 est axialement inséré dans l'interstice annulaire 30, suite à quoi les blocs de fixation 38 sont vissés sur les surfaces de fixation 20. Finalement, l'organe de calage 32 est poussé axialement vers l'extrémité de commande 10 par l'intermédiaire de vis 40 qui sont vissées dans le bloc de fixation 38.Then the wedging member 32 is axially inserted into the annular gap 30, whereupon the fixing blocks 38 are screwed onto the attachment surfaces 20. Finally, the wedging member 32 is pushed axially towards the end of control 10 by means of screws 40 which are screwed into the fixing block 38.

Ainsi, l'organe de calage 32 se dilate radialement sous l'effet de la surface de portée intérieure 18.Thus, the wedging member 32 expands radially under the effect of the inner bearing surface 18.

Sur la Figure 5 est représentée une variante d'un manchon d'adaptation 6 qui comporte, comme seule différence par rapport au manchon d'adaptation des Figures 1 à 4, des alvéoles 70 de réduction de poids.On the Figure 5 is shown a variant of an adapter sleeve 6 which comprises, as the only difference with respect to the adapter sleeve of the Figures 1 to 4 cells 70 of weight reduction.

L'invention apporte les avantages suivants.The invention provides the following advantages.

Les surfaces de butée 16, 26 coniques et les surfaces de portée 18, 28 sont faciles à fabriquer, ce qui permet de fabriquer l'ensemble 2 à faible coût.The abutment surfaces 16, 26 conical and the bearing surfaces 18, 28 are easy to manufacture, which allows to manufacture the assembly 2 at low cost.

Le fait que le dispositif de fixation 60 de plaques soit disposé sur le manchon d'adaptation 6 permet de changer rapidement le manchon d'adaptation 6 contre un autre manchon d'adaptation 6 également muni d'un dispositif de fixation de plaque, sans que le dispositif de fixation de plaques 60 ne doive être démonté.The fact that the plate fixing device 60 is arranged on the adapter sleeve 6 makes it possible to rapidly change the adapter sleeve 6 against another adapter sleeve 6 also provided with a plate fixing device, without the plate fixing device 60 must not be dismounted.

En outre, l'ensemble 2 selon l'invention comporte un manchon d'adaptation 6 supplémentaire non représenté et adapté pour être fixé sur le moyeu 4, les deux manchons d'adaptation 6 ayant des surfaces extérieures dont les circonférences sont différentes l'une de l'autre.In addition, the assembly 2 according to the invention comprises an additional adaptation sleeve 6 not shown and adapted to be fixed on the hub 4, the two adapter sleeves 6 having outer surfaces whose circumferences are different from each other. the other.
