Definitions

  • the present invention relates to a device for clamping of printing cylinders and turning them in electroplating plants and the use of said device.
  • the printing cylinders are surface-coated after cleaning and degreasing the surface with metal layers, most recently usually with Cu.
  • the print pattern is then etched or cut into the Cu surface layer.
  • the excess color is then removed by a doctor, so that color remains only in the low-lying printing elements.
  • the paper is pressed by means of a pressure cylinder to the printing plate, just a printing cylinder, whereby the color is transferred to the paper.
  • the inventive device now makes it possible to simplify this clamping and perform automatically.
  • the said guide rails and spindles are advantageously arranged so that neither by the clamping of the cylinder nor by their rotation in the electroplating baths, the position of the guide rails changed to the spindles or the straightness of the axis: spindle-cylinder spindle is affected.
  • the spindles are usually motorized on both sides and arranged movable in the same direction with respect to the device center and built into the carriage rifles are rotatable, sealing and the current formed conductive.
  • the said device can also - after the onset of the printing cylinder - run automatically by means of built-in control and regulation systems.
  • clamping and rotating device for secured by clamping receiving cylinders, in particular pressure cylinders, and rotation of the same, especially in electrolyte baths, wherein DC is supplied to the cylinder and the cylinder surface is coated metallically.
  • more than one cylinder can be simultaneously used and treated by means of appropriate adapter parts.
  • 1.1 denotes the base plate and 1.2 denotes one of the front plates of the device; the actual electroplating tub with the electrolyte solution is not shown.
  • the two guide and mounting rails 1.3 are arranged. On them run the two carriages 1.4, the position of which is adjusted and fixed by means of the adjusting and holding spindles 1.5.
  • the sleeves are 1.6, ie the devices for secure recording of the printing cylinder, housed to seal against the penetration of bath solutions in the sleeve and for supplying the necessary for the electrolytic coating of the cylinder surface DC.
  • the cylinder itself is designated 1.7 in FIG.
  • the drive for rotating the printing cylinder is based on the sleeves, so they are rotatably provided in the carriage;
  • the drive of the sleeves is done in a known manner from the outside.
  • the device according to the invention is used for receiving and rotating pressure cylinders secured in the various electroplating baths by means of clamping.
  • the slide with the specific sleeves against the front sides are moved apart and brought the cylinder to be treated - with emptied tub - by means of a movable support device between the - optionally replaced - sleeves.
  • the two carriages are now guided against the center of the device in opposite directions to the two cylinder axes and the cylinder is pressed firmly between the sleeves.
  • the bath liquid is then introduced and the current is connected to the sleeves; the electrolytic coating of the cylinder used can begin.

Claims (8)

  1. Dispositif pour monter et serrer des cylindres, notamment des cylindres d'impression, et pour les mettre en rotation dans des installations de galvanoplastie ou de traitement électrolytique, le dispositif étant adaptable en longueur relativement aux corps devant être revêtus et étant fixé aux parois frontales (1.2) d'un châssis, caractérisé
    - par deux glissières de guidage et de support (1.3 respectivement 2.1) disposées symétriquement par rapport à l'axe longitudinal du dispositif à côté et au-dessus de l'installation de traitement électrolytique,
    - par deux chariots (1.4 respectivement 2.3) fixés de manière mobile sur les glissières de guidage et comportant chacun un fourreau de maintien (1.6 respectivement 2.4) pour le cylindre, ainsi que
    - par des broches ou vis de déplacement de réglage et d'immobilisation (1.5) pour les chariots, qui sont agencées de manière centrée par rapport aux glissières de guidage et de façon décalée par rapport à celles-ci,
    les glissières de guidage étant fixées aux deux parois frontales (1.2) du dispositif et les broches ou vis y étant montées sur palier.
  2. Dispositif de serrage et de mise en rotation selon la revendication 1, par ailleurs caractérisé en ce que les glissières de guidage et les broches sont agencées de manière telle, que ni le serrage des cylindres, ni leur rotation ne modifie la position des glissières de guidage par rapport aux broches, ou n'entrave la conformation rectiligne de l'axe broche-cylindre-broche.
  3. Dispositif de serrage et de mise en rotation selon la revendication 2, par ailleurs caractérisé en ce que les broches sont motorisées des deux côtés et sont agencées mobiles de manière identique et selon des sens opposés par rapport au centre du dispositif.
  4. Dispositif de serrage et de mise en rotation selon la revendication 2 ou 3, par ailleurs caractérisé en ce que les fourreaux, dans les chariots, sont conçus rotatifs, étanches et conduisant le courant.
  5. Dispositif de serrage et de mise en rotation selon la revendication 4, par ailleurs caractérisé en ce que les chariots sont conçus de manière à pouvoir être aisément détachés des glissières de guidage.
  6. Dispositif de serrage et de mise en rotation selon l'une des revendications précédentes, par ailleurs caractérisé en ce qu'après la mise en place du cylindre d'impression, le dispositif fonctionne automatiquement au moyen de systèmes de régulation et de commande intégrés.
  7. Utilisation du dispositif de serrage et de mise en rotation selon les revendications 1 à 6, pour le montage sécurisé par serrage et la mise en rotation de cylindres, notamment de cylindres d'impression, plus particulièrement dans des bains d'électrolyte, du courant continu étant amené au cylindre en vue de munir la surface extérieure du cylindre d'un revêtement métallique.
  8. Utilisation selon la revendication 7, par ailleurs caractérisée en ce que l'on monte et traite simultanément plus d'un cylindre à la fois, au moyen de pièces d'adaptation appropriées.
