Definitions

  • the invention relates to a cleaning device Rotary printing machines for cleaning the lateral surfaces of Cylinders, with a cleaning cloth, with a pressure bar to press the cleaning cloth against the outer surface of the Cylinder, the cleaning cloth with cleaning fluid is wettable and with actuators for putting on and Place the pressure bar with the cleaning cloth, being on the cylinder to be cleaned in a cylinder channel Gripper fingers are provided.
  • the object is achieved in that the Pressure bar after one cleaning cycle Control signal triggered by a lifting element above the level the gripper finger is raised in the area of A cam segment is provided on the gripper finger, that on the pressure bar a swivel lever with cam roller it is provided that in the area of the gripper fingers Pressure bar is subjected to a pressure force and the cam roller contacts the highest curve section and that the curve segment then descending Has curve section, so that when turning the Cylinders over the cam roller and the swivel lever Pressure bar after the gripper fingers across the cylinder width is made to the lateral surface.
  • about the Pneumatic cylinder can be a uniform pressing force generate so that the profile rail an exact cleaning of the Feed the cylinder surface over the cleaning cloth can.
  • Control signal of the overpressure in the pneumatic cylinders switched off and serve as a lifting element on the springs Pressure bar, which the pressure bar in the area of Lift off the cylinder channel. Switching off the excess pressure can be delayed so that the pressure bar over a longer area is slowly lifted off. With this solution no disturbing blows can occur.
  • the pressure bar in off-hook Position at stops on a support frame and in position adjusted using set screws to execute. It is also advantageous that the pressure in the pneumatic cylinders is controlled by an angle encoder. This is a safe, harmonious process guaranteed.
  • the control signal for the lifting element is in advantageously transmitted by an angle encoder that is coupled to the cylinder.
  • FIGS Drawings An illustrative example of the invention is shown in FIGS Drawings shown schematically.
  • the cleaning device 1 is on a pressure cylinder 2 or by pivoting in its holder 4 on one Blanket cylinder 3 adjustable.
  • the bracket 4 is here provided on both sides between the machine side frames and enables the cleaning device 1 to be expanded.
  • a pressure bar 6 provided, which extends over the cylinder length.
  • the Pressure bar 6 is on both sides via pivot pin 7 on the Support frame 5 pivotally mounted.
  • the pressure bar 6 takes seen over its length on several spring bolts 8, which in Guide bodies 9, 10 are guided.
  • On the guide body 10 acts a compression spring 11 so that the rail 12 over the guide body 10 is resiliently supported. about the Pressure bar 12, the cleaning cloth 13 is guided.
  • the Nuts 14 on the spring bolts 8 allow adjustment of travel and limited in their investment in the Pressure bar 6 the travel.
  • Gripper fingers 17 are provided which are connected to a gripper pad 18 work together.
  • the gripper fingers 17 protrude here Shell surface 19 of the printing cylinder 2, as shown in the Figures 1 and 2 is shown.
  • the lateral surface 19 of the Printing cylinder 2 can be covered with a film by the cleaning device is cleaned.
  • Pneumatic cylinders 23 are on the support frame 5 attached, the piston rods 24 at Applying pressure medium via rollers 25, the pressure bar 6 pivots downward about the pivot pin 7.
  • the rollers 25 are on the pin 6 via roller pins 26 attached ( Figures 2 and 3). If the overpressure in the Pneumatic cylinders 23 switched off, so the Pressure bar 6 by tension springs 27 in that shown in Figure 1 Moved back position and thus the rail 12 with the Cleaning cloth 13 lifted from the outer surface 19.
  • the Tension springs 27 are between pins 28 on the support frame 5 are attached and pin 29, which on the pressure bar 6th are attached, excited.
  • the control signal for controlling the Cleaning device can be of a known per se Angle encoder are given, for example on the Printing cylinder 2 is attached.

Dispositif de nettoyage sur des machines à imprimer rotatives, destiné à nettoyer la surface latérale de cylindres, comprenant une toile de nettoyage, une barre de pression servant à presser la toile de nettoyage contre la surface latérale du cylindre, la toile de nettoyage pouvant être humectée avec un liquide de nettoyage, et des dispositifs de réglage permettant de mettre la barre de pression, avec la toile de nettoyage, en pression ou hors pression, dans le cas où des doigts de pinces sont prévus sur le cylindre à nettoyer, dans une rainure du cylindre,
    caractérisé en ce que :
    Figure 00120001
    après chaque cycle de nettoyage, avec déclenchement par un signal de commande, la barre de pression (6) est soulevée au-dessus du niveau des doigts de pinces (17) par un élément élévateur (27),
    il est prévu au moins un segment de came (23) sur le cylindre (2) dans la région des doigts de pinces (17),
    sur la barre de pression (6), il est prévu un levier oscillant (20) muni d'un galet de contre-came (21 ),
    dans la région des doigts de pinces (17), la barre de pression (6) est sollicitée par une force de pression et le galet de contre-came (21) est mis en contact avec le segment le plus haut de la came, et
    le segment de came (22) présente ensuite un segment de came descendant (34), de sorte que, lorsque le cylindre (2) continue à tourner, la barre de pression (6) est mise en pression contre la surface latérale (19) sur toute la largeur du cylindre, en aval du doigt de pince (17), sous l'action du galet de contre-came (21) et du levier oscillant (20).
  2. Dispositif de nettoyage selon la revendication 1, caractérisé en ce qu'à la barre de pression (6), sont associés des cylindres pneumatiques (23) qui produisent la force de pression et en ce que la toile de nettoyage (13) est appliquée contre la surface latérale (19) au moyen d'un profilé élastique (12) prévu sur la barre de pression (6).
  3. Dispositif de nettoyage selon la revendication 1, caractérisé en ce que le signal de commande met à l'arrêt la surpression dans les cylindres pneumatiques (23) et il est prévu, comme élément élévateur, des ressorts (27) portés par la barre de pression (6), qui soulèvent la barre de pression (6) dans la région de la rainure (15) du cylindre.
