Definitions

  • the invention relates to a control for a printing press according to the preamble of Claim 1.
  • Sheet-fed offset printing machines generally have a device on the plate cylinder to decouple the plate cylinder from the drive gear and the gear train. Devices are known in which the plate cylinder up to one entire rotation can be rotated relative to the drive gear. Such facilities are often called circumferential coarse register adjustment.
  • an angle encoder incrementmental encoder, absolute angle encoder
  • the plate and blanket cylinders can be moved into certain positions, so this is only possible if the plate cylinders in the so-called Are zero position, i.e. a previous coarse circumference register adjustment again has been canceled.
  • DE 3 342 662 A1 describes a device on a printing press consisting of a Plate and / or blanket cylinder known, in which on the plate cylinder Actual position encoder is attached, by means of this in connection with predetermined target values the plate cylinder and / or the blanket cylinder in predetermined positions can be moved.
  • This actual position encoder can be an angle encoder or but it can also be a contactlessly scanning switch.
  • Adjustability of plate cylinders is not dealt with in this document, so that at one To arrange printing machine with several printing units according to several angle encoders are what can be regarded as disadvantageous due to the high construction costs.
  • the object of the present invention is therefore a control device according to the preamble of claim 1 to further develop such that in a simple manner compared to Main drive adjustable cylinders can be moved exactly to specified positions can.
  • FIG. 1 shows the first five printing units of a sheetfed offset press in a row.
  • An angle encoder WG is attached to a system drum A, which is designed as an absolute encoder according to the exemplary embodiment.
  • the position signals this angle encoder WG are fed to a controller S.
  • the control S is connected to the main drive HA of the printing press and gives to it appropriate commands to move to specified target positions. These are in the controller S stores a plurality of (first) target angle values which determine Positions of the plate cylinder P in the individual printing units correspond.
  • target angle values for a plate cylinder are present So around this plate cylinder, for example, in a position for inserting one Pressure plate in the pressure start clamping rail, for inserting the pressure plate trailing edge position in the print end clamping rail etc.
  • control S target angle values for the individual plate cylinders are also stored in the printing units, which serve the cylinder-related activation of certain actuators. Be here for example, the turning on and off of dampening and / or inking rollers.
  • the plate cylinders P are assigned fixed sensors SR, which feel the markings made on the individual plate cylinders P.
  • the individual sensors SR give a signal with each rotation of the plate cylinder P. when the mark passes the respective sensor.
  • the control S also contains (second) angular position values for the individual plate cylinders P stored, which correspond to those angle values when the sensors SR detect the markings on the plate cylinders P in the undisguised basic state.
  • the controller S now performs a comparison of the actual angular position for each sensor SR when emitting a signal with the associated stored angle value. Is this difference is zero, the plate cylinder is not adjusted, so it is in its basic position. Now this plate cylinder is to be moved to a predetermined position be, e.g. B. for inserting a pressure plate leading edge into the pressure start clamping rail, the control S does this with the corresponding stored (first) Target angle values in connection with those recorded via the angle encoder WG Actual angle values by.

Claims (2)

  1. Dispositif de commande pour une machine d'impression, notamment pour une machine d'impression offset à feuilles, qui comporte un capteur angulaire à un tour relié à une commande, des positions prescrites des cylindres étant atteintes par l'intermédiaire de la commande qui est en liaison active avec la commande motrice principale de la machine d'impression en comparant les valeurs angulaires réelles fournies par le capteur angulaire à des valeurs angulaires de consigne mémorisées,
       caractérisé en ce que
       des palpeurs (SR), qui sont fixés au bâti et qui détectent sans contact des repères placés sur les cylindres porte-plaques (P), sont associés aux cylindres porte-plaques (P), les palpeurs (SR) sont reliés à la commande (S) et celle-ci contient en mémoire, outre des premières valeurs angulaires de consigne pour atteindre des positions prescrites, des deuxièmes valeurs angulaires qui sont obtenues lorsque les palpeurs (SR) détectent un repère d'un cylindre porte-plaque (P) non réglé, et la commande (S) est conçue de manière à déterminer à chaque fois une différence entre la valeur angulaire actuelle lors de la sortie de signal d'un palpeur (SR) et la deuxième valeur angulaire mémorisée associée pour un cylindre porte-plaque (P) non réglé et à inclure cette différence dans les calculs pour atteindre une position prescrite pour ce cylindre porte-plaque (P) en relation avec la valeur angulaire de consigne associée.
  2. Dispositif selon la revendication 1,
       caractérisé en ce que
       la commande (S) permet d'effectuer un contrôle des signaux des palpeurs (SR) pour tester la présence d'un changement de flanc pendant que la machine tourne.
