Definitions
- the object of the invention is therefore to provide a printing press of the type specified at the outset, in which a loss of production due to the transition from one print job to another can be almost completely avoided and the degree of utilization of the printing press can thereby be increased considerably.
- this object is achieved in a printing press of the generic type in that each format cylinder can be uncoupled from the main drive of the impression cylinder by a coupling device and is provided with a controllable servo motor which accelerates the format cylinder to the peripheral speed of the impression cylinder, and in that the format cylinder in question is reached when it is reached the synchronous speed can be coupled again to the main drive of the impression cylinder.
- printing machine according to the invention printing of a new printing job of a completely different type can be started immediately after a printing job has ended, without the printing machine as a whole having to be shut down and converted.
- the printing press according to the invention makes it possible to print the web running through the printing press at an undiminished speed following a print job in a different manner on the basis of a new print job without any significant waste occurring between the two print jobs.
- the new format cylinder intended for the next print job is accelerated by the servo motor to this synchronous speed, so that the format cylinder rotates at synchronous speed, i.e. a peripheral speed that is the speed of the web to be printed or the peripheral speed of the impression cylinder corresponds.
- synchronous speed i.e. a peripheral speed that is the speed of the web to be printed or the peripheral speed of the impression cylinder corresponds.
- the format cylinder of the last print order is moved to the "print stop” while the drive gear of the new format cylinder is brought into meshing engagement with the impression cylinder gear and into the print position.
- the gear wheel of the new format cylinder can still be brought into a position relative to the impression cylinder while the last print job is being carried out, which corresponds to the usual printing shutdown.
- the counter-pressure cylinder gear that meshes with the format cylinder of the current job, coupled to the impression cylinder, while the gearwheel mounted on the other shaft journal of the impression cylinder is initially freely rotatable.
- the gear wheel of the format cylinder of the next print job can now be brought into a loose engagement corresponding to the printing cut-off with the associated impression cylinder gear.
- the servo motor now brings the new format cylinder and with it the still freely rotatable counter-pressure cylinder gear to the synchronous speed.
- the impression cylinder gear is coupled to the main drive, so that both format cylinders receive the synchronous speed via the main drive.
- the format cylinder of the last job can now be moved to the print stop and at the same time the format cylinder of the new print job can be moved to the print job, so that one print job can be transferred to the other without interrupting the printing operation and practically without waste.
- Disengageable toothed or claw clutches can be provided for coupling and uncoupling the gearwheels to the two shaft journals of the counter-pressure cylinder.
- These couplings can be of any known type. Pneumatically or magnetically foldable couplings are expediently provided, of which a ring is held fixed to the frame.
- Both format cylinders of a print stand can be driven by a single servo motor.
- the servo motor can be in a drive connection with a shaft, which can be coupled or uncoupled via a clutch / brake combination either to a gearwheel or gearbox, which drives one of the gearwheels mounted on the shaft journal of the counter-pressure cylinder.
- the clutch brake combination is switched by the associated control system so that the clutch on the side to be accelerated is closed and the brake is released during startup.
- the clutches and brakes of the two clutch and brake combinations on the two sides of the shaft are switched so that when the clutch is open, the brake only engages when the format cylinder of the last job moves into the print position and the impression cylinder gear driving it from the shaft journal of the impression cylinder has been uncoupled.
- the format cylinder of the last job can then be exchanged for a new one for the next but one print job.
- these can expediently be adjusted offset by 180 degrees on the impression cylinder, and preferably in a horizontal plane.
- Printing stands of the type described are arranged one behind the other, each of which has two printing units, the two format cylinders each printing one color.
- the servomotors of the format cylinders in the closer printing stands are controlled in such a way that they accelerate the format cylinders relative to one another at an exact angle, that is to say in register, with the same circumferential speed to the circumferential speed of the impression cylinders. This is done by correspondingly joint control of all servomotors, which can be driven with high accuracy at the same speed at the same angular position.
- This condition applies to both start-up and run-down.
- This means that all format cylinders are inserted with the register of the corresponding angular position without this angular position changing during the run-up.
- the format cylinders also maintain the angular position corresponding to the register after they have stopped.
- the other printing unit can be converted to the next order during a current job and practically start with the new print job without waste.
- a printing stand with an impression cylinder 3 and two printing units 4, 5 is shown, which can be understood as a one or two color printing machine or as part of a multi-column multi-color printing machine, for example a multi-color printing machine with four or six stands.
- the pressure stand consists of the side frames 1, 2, which are connected to one another by crossbeams (not shown) and between which the impression cylinder 3 is mounted in the usual way.
- the format cylinders 6, 7 of each printing unit are offset by approximately 180 degrees on opposite sides in an approximately horizontal plane in format cylinder carriages, not shown, which are guided in guides of the printing stand and can be adjusted and removed from the impression cylinder 3 by spindle drives.
- format cylinder and inking roller carriages are also not shown in FIG. 2 and instead the format cylinders and inking rollers are mounted in the side frames.
- the impression cylinder 3 is driven via the main drive shaft 10 and the worm gear 11, the output shaft 12 of which is connected via the coupling 13, which compensates for any axial misalignment, to the shaft journal 14 of the impression cylinder 3 which projects beyond the side frame 1 of the pressure stand.
- the main drive shaft 10 connects the printing stands of the printing press arranged in a row to one another, the shafts arranged between two printing stands being connected to the input and output shaft journals of the worm gear 11 also by known couplings 13 which compensate for a possible axial offset.
- the shaft journals of the format cylinders 6, 7 have gear wheels 22, 23 on opposite sides, which can be brought into meshing engagement with the gear wheels 17, 18 of the impression cylinder.
- the web 50 to be printed runs over the guide roller 51 and the impression cylinder 3 in the manner shown. they runs in a corresponding manner over all the impression cylinders of the other printing stands, with corresponding guide rollers, not shown, being provided.
- the printing stand is part of a multicolor printing machine, the format cylinder 7 printing the web 50 with one of a plurality of colors.
- the format cylinder 6 is already prepared for the next print job. If the current print job is now finished, the format cylinder 6 is accelerated by the servo motor 38 in phase with all other format cylinders for the new print order of the further print stands to the synchronous speed of the web 50 to be printed.
- the gear 17 is coupled to the shaft journal 14 of the impression cylinder 3 via the tooth coupling 19, while the format cylinder 6 and the corresponding format cylinders of the other print stands for the new print job are in the print stop. If the command to change the print job is now given, the still printing format cylinder 7 and the corresponding format cylinder of all other printing stands of the printing press are moved into the printing position, while all of the format cylinders for the new print job are set simultaneously on the respective impression cylinders.
- the clutch brake combinations 34, 35 are then switched in such a way that the servomotors are uncoupled and the brakes for braking the format cylinders are applied for the previous print job after the corresponding transmission gearwheels 18 have been uncoupled from the counterpressure cylinders via the associated toothed clutches.
