  • FIG. 1 is a side view of a side frame of a Fiexo printing machine, in which the bearing blocks of a printing roller and an anilox roller are mounted, which can be adjusted against each other and against an impression cylinder,
  • FIG. 2 shows a schematic representation of a top view of a pressure roller which is mounted on the fly in a side frame with the interception bearing removed and a device for pushing off a casing sleeve and / or an adapter sleeve from the pressure roller.
  • Fig. 3 shows a section through the pressure roller along the line III-III in Fig. 2 and
  • Fig. 4 A to D different positions of on swiveling and movable in the axial direction thrust pieces on sleeves and / or adapter sleeves to be pushed out.
  • FIG. 1 shows a side view of the front of two cantilevered side frames 1 connected to the printing press frame, which are provided with windows forming openings 2, in the region of which on guide rails
  • the bearing blocks 4, 5 of a printing roller 6 and an anilox roller 7 are movably mounted in such a way that the anilox roller 7 on the printing roller 6 on and from this can be switched off and the printing roller 6 alone or together with the anilox roller 7 on the impression cylinder 8 is adjustable.
  • the two bearing blocks 4, 5 of a printing roller 6 and an anilox roller 7 are movably mounted in such a way that the anilox roller 7 on the printing roller 6 on and from this can be switched off and the printing roller 6 alone or together with the anilox roller 7 on the impression cylinder 8 is adjustable.
  • the two bearing blocks 4, 5 of a printing roller 6 and an anilox roller 7 are movably mounted in such a way that the anilox roller 7 on the printing roller 6 on and from this can be switched off and the printing roller 6 alone or together with the anilox roller 7 on the impression cylinder 8 is adjustable.

  • the front shaft journal 12 of the pressure roller 10 is mounted in an interception bearing 13 during the printing operation, which in the position shown in FIG. 2 has been released from the shaft journal 12 and moved to the side, so that the pressure roller and the jacket sleeve 14 held thereon and the these carrying adapter sleeve 15 are freely accessible through the window 2 of the front side frame 1.
  • the shafts 17, 18 are guided and mounted in a slowly displaceable and rotatable manner parallel to one another and at a distance and symmetrically to a vertical plane intersecting the center line of the pressure roller 10 below the pressure roller 10.
  • radial arms 20 are fastened in a non-rotatable manner, the ends of which protrude freely upward carry jaws in the form of pressure pieces 21.
  • the rear ends of the shafts 17, 18 are rotatably but axially immovable in a plate-shaped holding piece 22.
  • Radial levers 23 are non-rotatably fastened to the rear shaft journals of the shafts 17, 18 passing through the holding piece 22, on the free ends of which the cylinder 24 and on the other hand the piston rod 25 of a pressure medium-piston-cylinder unit are mounted.

  • 4B shows the right part encircled in FIG. 2.
  • the buffering part 22 of the pressure piece 21 is only applied to the end face of the casing sleeve 14, so that initially only this can be pushed off the adapter sleeve 15.
  • the pressure piece 21, which is specially designed according to FIG. 4 C, is provided with a shoulder 35 which abuts an annular projection 36 of the adapter sleeve 15 and thus pushes it off the pressure roller 10 when the jacket sleeve is already a predetermined distance from the adapter sleeve 15 has been deported.
  • This type of gradual pushing off facilitates handling when the adapter sleeve with the sleeve from the Printing roller is pushed off, because then the jacket sleeve can be removed more easily from the adapter sleeve.
  • the casing sleeve 14 is provided with an annular groove into which the wedge-shaped, buffering piece 22 of the pressure piece 21 engages, so that the casing sleeve 14 is pushed off by itself from the adapter sleeve 15 or else is pulled onto it can.
  • the pressure piece is provided with a sensor, for example an optical sensor 37, which detects a mark attached to the casing sleeve, so that the rotational position of the casing sleeve can be detected for the pressure absorption.

Abstract

Les paliers d'un cylindre d'impression d'une presse à imprimer, de préférence une presse flexographique, comprenant au moins un cylindre à contre-pression et au moins un cylindre d'impression monté dans le bâti de façon mobile au niveau d'une extrémité, peuvent être déplacés par rapport au cylindre à contre-pression dans des coulisses, le tourillon de l'extrémité libre du cylindre d'impression étant soutenu par un palier. L'objectif de cette invention est de permettre de retirer, de manière simple, le manchon de gainage et/ou le manchon d'adaptation du cylindre d'impression. A cet effet, deux arbres sont montés de façon à pouvoir effectuer une rotation et un déplacement longitudinal, parallèlement à la ligne médiane du cylindre d'impresssion, dans le support de palier supportant le cylindre d'impression de façon mobile, lesquels arbres portent, au niveau de leurs extrémités intérieures faisant face au cylindre d'impression, des bras radiaux pourvus de pièces d'appui côté extrémité. Ces arbres sont montés, au niveau de leurs extrémités extérieures, de façon à pouvoir effectuer une rotation dans une pièce de maintien et sont équipés d'un mécanisme d'entraînement en rotation. Cette pièce de maintien est équipée d'un mécanisme d'entraînement pouvant être déplacé par rapport au support de palier.
