Definitions

  • the invention relates to a method for presetting the forme cylinders, each provided with a mark, of multi-color web-fed rotary printing presses, in which the forme cylinders are decoupled from their drives to markings fixed to the frame for setting their starting positions according to the position of their markings, and then according to the length of the web between the respective markings fixed to the frame and the marking of the first forme cylinder are coupled again to their drives, and a device for carrying out this method.
  • the markings of the forme cylinder uncoupled from their main drive shaft are brought to cover their initial positions with marks fixed to the frame, and then the forme cylinders following the first forme cylinder are sequentially removed from their initial positions . rotated relative to the respective previous forme cylinder by an angle which results from the quotient of the remainder of the path length divided by the forme cylinder circumference and lying between two markings and the cylinder circumference.
  • the forme cylinder rotated in this way is then coupled again to the main drive shaft.
  • a device that can be connected to the main drive shaft is provided for determining and displaying the angle of rotation.
  • the second forme cylinder in the web running direction is switched on and the angular position of the forme cylinder is saved as a cylinder impulse on its scanning device on its scanning device.
  • the forme cylinder of the second printing unit is then switched off and the first forme cylinder is switched on, and the path traveled between the occurrence of the cylinder pulse and the detection of the register mark of the first forme cylinder on the scanning device of the second forme cylinder is used as a register setting command.
  • the respective angles of rotation are recorded in digitized form so that, for example, microcomputers can be used for control.
  • Both methods of register presetting are relatively complex because the coupling of the forme cylinders to their drives can only take place after the respective angles of rotation have been determined by calculation.
  • the object of the invention is therefore to provide a simpler method for presetting the register of the forme cylinders.
  • this object is achieved in a method of the type specified at the outset in that the web to be printed is moved into the printing press and printed with the register marks of the printing units, and the form cylinders of the printing units following the first printing unit are uncoupled from their drives at the time, in which the register marks printed by these are detected by a photo button assigned to the respective forme cylinder, forming a frame-fixed marking, and in that the forme cylinders are coupled in turn to their drives when the respective, assigned photo button is the print mark of the forme cylinder of the previous one Printing unit detected.
  • the registers of the forme cylinders can be preset in a simple manner and with high accuracy.
  • waste can also be saved in that the forme cylinders following the forme cylinder of the first printing unit are uncoupled from their drives when the register marks printed by them are detected by the associated photo sensors and recoupled when the photo buttons the subsequent register marks of the first forme cylinder.
  • the forme cylinders can only be preset when the web is running.
  • the method according to the invention can be carried out in accordance with the device in that electrically operable plate or toothed clutches are provided for coupling and uncoupling the forme cylinders.
  • the web 3 to be printed is drawn off from the supply roll 2 and fed to the printing units 11, 12, 13, 14 of the multi-color rotary printing press 1.
  • the individual printing units 11, 12, 13, 14 are provided with forme cylinders 4 and impression cylinders 5.
  • the printed web is fed over known and not designated guide rollers and dried in a known manner.
  • the inking units through which the forme cylinder 4 are colored have been omitted for the sake of clarity.
  • the forme cylinders 4 are driven by a main shaft 6, the axes of the forme cylinders 4 carrying bevel gears which mesh with the bevel gears 11.1 to 14.1.
  • the bevel gear 11.1 is fixed immovably on the main shaft 6.
  • the bevel gears 12.1 - 14.1 are connected to the main drive shaft by means of hollow brake shafts 22 - 24 which are displaceable on the main drive shaft.
  • the hollow shafts can be designed as multi-spline shafts, so that the bevel gears 12.1 - 14.1 are axially displaceable but non-rotatable relative to these.
  • the hollow shafts carry the shift plates 22.1 - 24.1 of the clutch brake devices formed from multi-plate clutches.
  • clutch plates 22.2 - 24.2 are rotatably connected to the main shaft.
  • brake discs 22.3 - 24.3 are fixed to the frame of the machine, so that by shifting the hollow shaft, the non-rotatably connected switching plates can be coupled to the clutch plates of the main shaft 6 and to brake and lock the forme cylinders with the fixed brake plates.
  • photocells 32-34 are arranged fixed to the frame and are directed at registration marks which are printed on the web 3 by the forme cylinders 4.
  • the form cylinders 4 are preset as follows: The form cylinders 4 are initially installed regardless of the position of your registration marks. An unprinted web will then run in at feed speed relaxed and printed with all colors. As soon as the printed marks dercem first printing unit following the printing units 12, 13, 14 under the associated photocells (32, 33, 34) appear to be shut down the associated form cylinder by a cell of the photo emitted signal by means of the K upplungs-braking devices and in held this position. In these print-down positions, the forme cylinders are parked on the web so that it can pass through the printing machine without hindrance. As a result of this process, all forme cylinders following the forme cylinder of the first printing unit are aligned relative to the associated photocells and thus also to one another.
  • the registration mark printed by the first printing unit 11 now appears under the photocell 32 of the second printing unit 12, its forme cylinder 4 is coupled to the main shaft 6 and at the same time again placed on the web.
  • the registration mark printed by the first printing unit 1.1 passes under the photocell 33, the forme cylinder 4 of the printing unit 13 is coupled in and so on until all forme cylinders 4 are in drive connection with the main shaft 6 and are in contact with the web. Printing can begin immediately. H. the machine can run up to the printing speed, because the registration marks are now in the capture area of the photocells, so that the. Register control can take effect.
  • the printing unit is switched to "print-on" before disengaging and "after printing".
  • the pre-adjustment of the forme cylinders can also be done in the following way to further reduce waste:
  • the forme cylinders 4 of the printing units 11, 12 print their registration marks on the incoming web. If the photocell 32 of the printing unit 1.2 detects the registration mark printed by it, the forme cylinder of the printing unit 12 is stopped. When the registration mark printed by the printing unit 11 passes shortly thereafter under the photocell 32, the forme cylinder 4 of the printing unit 12 is coupled again. At the same time, the forme cylinder 4 of the printing unit 13 is also coupled to the main shaft 6 and when the registration mark printed by it passes under the photocell 33, the forme cylinder of the printing unit 13 is stopped again.
  • the forme cylinder 4 of the printing unit 13 is engaged again and at the same time the forme cylinder 4 of the printing unit 14 is switched on.
  • the registration mark printed by the latter passes through the photo cell 34 assigned to it, the forme cylinder of the printing unit 14 is stopped again and only switched on again when the registration mark printed by the printing unit 11 reaches the photo cell 34.
