Definitions

  • 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.
  • open matching sleeves having different thicknesses may be mounted on a hub.
  • a sleeve is for example disclosed in the application WO2005 / 014286 of the Applicant.
  • 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.
  • 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 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.
  • 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.
  • the hub 4 comprises a control end 10, connected to drive means, such as an electric motor, as well as a function end 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.
  • abutment surface 16 and the bearing surface 18 are each connected in a non-stepped manner to the cylindrical central outer surface 14.
  • 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.
  • 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.
  • 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.
  • the inner surface 24 is adapted to bear on the outer surface 14 of the hub 4.
  • 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.
  • 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.
  • 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 .
  • 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 .
  • a thrust screw 40 which is adapted to axially push the clamping member 32 towards the control end 10.
  • 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.
  • This light 42, the tapping is a not shown extraction screw form extraction means of the wedging member 32 out of the gap 30.
  • the assembly 2 further comprises indexing means 50, adapted to fix the adapter sleeve 6 on the hub 4 in a defined circumferential position.
  • 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.
  • 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.
  • the mounting of the adapter sleeve 6 on the hub 4 is performed as follows.
  • 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.
  • the recess 58 is circumferentially aligned with the notch 52 and the indexing key 54 is screwed into the recess 58.
  • 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.
  • wedging member 32 expands radially under the effect of the inner bearing surface 18.
  • FIG. 5 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.
  • the invention provides the following advantages.
  • 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.
  • 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.
  • 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.
