Definitions

  • the invention relates to a Abfanglagerung for a Farbübertragungs- or counter-pressure roller.
  • Ink transfer rollers is a generic term for all rollers that transport a fluid, such as paint or fountain solution, within a printing press.
  • anilox rollers which remove ink from a color reservoir, usually a doctoring chamber, and format cylinders, which are supplied with clichés, which in turn remove ink from the anilox rollers and transfer it to the printing material.
  • a Abfanglagerung mentioned for the types of rollers described is frequently, but not exclusively, used when such rollers comprise a mandrel, which can be acted upon with one or more sleeves, wherein the outermost sleeve has a functional layer for fluid transmission, such as the print motif visual cliché, or to Transport of the printing material includes.
  • the sleeves are replaced instead of whole ink transfer rollers.
  • the mandrel remains in the printing press while being held single-ended while the second end is exposed to allow sleeves to be withdrawn from the mandrel in the axial direction and slid on. In printing operation itself, however, a double-ended storage is recommended to avoid vibrations of the ink transfer or counter-pressure roller.
  • the object of the present invention is therefore to propose a Abfanglagerung for each at least one end of ink transfer rollers, which are less expensive.
  • the support element comprises at least two pieces of pipe or sleeves, which are positively pushed onto receiving elements such as bolts or guide pins. These receiving elements are fastened to the support element.
  • receiving elements such as bolts or guide pins.
  • a bearing is fixed, which is displaceable and rotatable on the guide pin.
  • the support element can be moved in the axial direction.
  • the bearing can be removed from the end of the roller.
  • Said embodiment of the invention now makes it possible to swing the support member about the axis of the guide pin, so that the roll end is easily accessible.
  • an arresting device is provided in an advantageous development of the invention, which prevents unwanted displacement of the support element relative to the support element in the direction of the roll axis.
  • FIG. 1 is a front view of an inventive Abfanglager Fig. 2 view of the section N-II in Fig. 1st
  • Fig. 1 and Fig. 2 show a Abfanglagerung 1, which comprises a support member 5.
  • This support element 5 carries a bearing 4, for example a needle bearing, which encloses the visible end of the mandrel 2.
  • This end of the dome 2 can for easier sliding of the bearing 4 to the end face slightly rejuvenate.
  • a sleeve 3 often called sleeve, postponed.
  • the interceptor further includes a support member 6. This support member may be attached directly to the machine frame of the printing press.
  • support element can also be designed as a slide, which along arranged on the machine frame guides, for example
  • Guide rails can be moved. This is important, for example, when the ink transfer roller to a printing material, which is passed over a second roller, to be employed.
  • a guide pin 7 extending away from the ink transfer roller (counter to the direction z) is fastened on the side remote from the ink transfer roller.
  • On this bolt is supported by a ball bearing 8 from a sleeve piece 9, which is both in the direction of z slidably and rotatable about the guide pin.
  • the sleeve piece 9 is immovably fitted in a pipe section 10, so that no radial displacement of the sleeve piece 9 in the pipe section 10 is possible.
  • the pipe section 10 projects beyond the sleeve piece 9 in its axial length, wherein the end of the pipe section 10 projecting beyond the sleeve piece 9 widens in the direction z and thus forms an inner cone.
  • the original diameter of the inner cone may differ from the inner diameter of the region in which the sleeve piece 9 is introduced.
  • the pipe section 10 is fastened to the support element 5.
  • the mandrel 2 is supported in this way so on the bearing 4, the support member 5, the pipe section 10, the sleeve piece 9 and the ball bearing 8 on the guide pin 7 from.
  • a guide pin 7 surrounding ring 1 1 is fixed, which has a z larger diameter in the direction of outer diameter, wherein the pipe section 10 is tuned with its inner cone 12 on the outer cone of the ring 1 1.
  • the pipe section 10 is displaced in the axial direction of the guide pin 7, so that the inner cone is pushed onto the ring and thus due the form-locking of both elements centered.
  • the pipe section is thus displaced neither in the direction x nor in the direction y.
  • the pipe section may be provided with an outer cone and the ring with an inner cone to achieve the same effect.
  • a locking device which fixes the support member 5 to the support member 6 and thus the pipe section 10 presses against the ring 1 1.
  • the locking device comprises a hand lever 13, with which a bolt 14 is rotatable.
  • This bolt 14 is rotatably mounted in an attachment 15 of the support member 5 and can be locked to the support member 6 via a quick release mechanism.
  • a further sleeve 16 is arranged on the support member 5, which comprises an inwardly directed paragraph 17 at its pointing away from the support member end.
  • the sleeve 16 has a diameter which increases in diameter in the axial direction, ie in turn has an inner cone 19.
  • the paragraph 17 has an inner cone 18, which expands seen in the direction z.
  • the sleeve 16 comprises a bolt 20 fastened to the support frame 6. This bolt comprises an outer cone matched to the inner cone 18 of the shoulder 17 and, spaced apart axially therefrom, an outer cone matched to the inner cone 19.
  • Such configured Abfanglagerung whose support member is positively locked on at least two in the direction x and / or in the direction y points on the support member, has a high stability, resulting in lower vibrations of the Farbübertragungs- or the Counterpressure roller and thus expressed in a better print quality.
  • a movement in the direction z is prevented by the manually feasible locking of the support member by the bolt 14, which is mounted in this axially immovable.
  • Such a solid and stable connection between support and support element has not been achieved in any manually operable Abfanglagerung.
  • the locking of the support member is released by the operation of the hand lever. Then, the support member along the guide pin 7 is pulled away from the support member, wherein the distance A, by which the support member is pulled, sufficient to completely remove the bearing 4 of the mandrel 2. Then, the entire support member can be pivoted about the guide pin in the pivoting direction B, so that no component of the support member protrudes more in the cross section of the sleeve 3. This sleeve can then be removed undisturbed from the mandrel.
