Definitions

the invention relates to a device for stable machine operation Printing units of a rotary printing press for operation with part width Printing material according to claim 1.
WO 02058931 A2 describes a device for improving the The printing process, for example in the case of production with part-width paper webs, being on the non-printing areas of the rollers of the inking unit, in particular on the two ends of these rollers, an ink dissolving or decomposing solvent is applied or applied dropwise to the ink applied and accumulated at the ends of the rollers on one Loss of solvent and thus of a resulting drying out and Prevent ink from sticking.
the invention is based on the object of eliminating the disadvantages mentioned above and a device for stable machine running on printing units Offset rotary printing machine for operation with changing and partly wide To create printing material, by means of which the ink does not dry out printing areas of the rollers and cylinders of the printing unit is prevented and thus the stickiness - the so-called tack - on a low level is held to reduce the risk of web breaks, as well as the burden on the Reduce rollers and blankets.
the device is used to apply a non-flowing medium, for example a commercially available roller paste or roller grease, to the non-printing areas of a cylinder or roller in the inking or dampening unit in a finely distributed manner by means of blown air.
a non-flowing medium for example a commercially available roller paste or roller grease
the non-flowing medium adheres to the surface of the cylinder or roller and prevents the ink from drying out and accumulating.
the non-flowing medium is applied to the surface, ie to the non-printing areas, of the cylinder or roller in the inking or dampening unit by means of compressed air by means of a pump system with a distributor unit.
the non-flowing medium can be applied, for example, by means of a metering nozzle on the rider roll, for example a ceramic rider roll, or on any other incoming nip.
Splitting processes distribute the non-flowing medium to the non-printing areas in the entire inking unit or in the entire roller mill. When operating with a wide web, ink collects in the non-printing zones.
squeegee units can also be adjusted to the non-printing areas of the rider roller in order to remove the mixture of printing ink and non-flowing medium that adheres and accumulates in the course of the printing process.
the ink Due to the axial movement of the distribution cylinder in an inking unit, the ink has the property during the printing process that it migrates outwards on the individual rollers and / or cylinders and builds up on the rollers.
the color build-up on the one hand causes spraying and contamination of the machine, on the other hand the color build-up causes greater wear on the rollers and blankets and reduces their service life.
the squeegees determine the track edge of the color strip.
the width of the individual doctor blades can also be adapted to the width of the ink-free zone, the doctor blades of different widths being arranged interchangeably.
the doctor units are operated from the control center. For example, after a time cycle that can be set at the control station, the ink / protective medium mixture is removed by the doctor device, for example, from the rider roll or other rolls and / or cylinders, both the switch-off and switch-on times being freely selectable depending on the production requirements. After each adjustment or doctoring process, fresh, non-flowing protective medium, for example roller paste, is applied with a short time delay and the cycle begins again.
the doctor blades can be turned on and off by means of a pneumatic cylinder, the contact pressure of the doctor blade being adjustable on the rider roller. The squeegee must be set evenly but only slightly in order to avoid excessive wear.
the automated dosing of roller paste in the edge areas of the inking unit or the printing unit reduces the load on the rubber cylinder sleeve, the rubber blanket and the inking rollers, especially for part-width productions.
a corresponding number of doctor blades are to be attached.
the ink / protective medium mixture removed from the squeegee is collected in an ink pan which is arranged below the squeegee. This must be emptied from time to time.
At least 2 lubrication points are provided on a printing unit in order to allow the to be able to apply the non-flowing medium to non-printing areas.
FIG. 1 shows an offset rotary printing press 1 consisting of four Printing units 2 to 5, printing units 2 to 5 being a printing material 6 can print on both sides, for example.
the printing substrate 6 shown in FIG. 1 does not create the total printing width 8 of individual rollers 9 and 10 cylinders Printing units 2 to 5, so that at the respective edge zones of the rollers 9 and Cylinder 10 non-printing areas 11 and 12 arise.
the printing units 2 to 5 thus print on a part-wide substrate 6.
dispensing nozzles 13 are arranged by means of which With the aid of blown air, a non-flowing protective medium 14 is applied to the surface. of the respective rollers 9 and / or cylinder 10 is applied in finely divided form.
the Protective medium 14 is in the viscosity range of approx. 300 to 400 dPa * s.
FIG. 2 shows one of the printing units 2 to 5, the printing material 6 being passed between two transfer cylinders 15, 16 and being printed on both sides.
the transfer cylinders 15, 16 are connected to forme cylinders 17, 18, the forme cylinders 17, 18 being supplied with printing ink and dampening solution by inking 19, 20 and dampening units 21, 22 constructed from several rollers.
a squeegee unit 23 can be turned on and off on at least one of the rollers of the inking units 19, 20 and / or dampening units 21, 22 and / or on one of the cylinders 15 to 18 on its non-printing areas 11, 12.
the doctor unit 23 can be turned on and off on a rider roller 24 of the inking and dampening unit roller train.
the metering nozzles 13 are arranged, for example, on the rider roller 24 and / or on an incoming nip 40 between a transfer roller 7 and the rider roller 24, or on any incoming nip.
Splitting processes distribute the non-flowing protective medium 14 to the non-printing areas 11, 12 in the entire inking unit 19, 20 or in the entire roller mill in accordance with the width of the non-printing area 11, 12.
the metering nozzles 13 can be positioned and / or activated according to the width of the non-printing area 11, 12, wherein a plurality of metering nozzles 13 can be arranged on the non-printing areas 11, 12 and by means of a computer and / or control unit, by means of the control station or can be controlled, activated and / or positioned by means of the machine control.
the dosing nozzles 13 are supplied with the protective medium 14, for example, by a pump system 25 with a distributor unit 26.
the control or regulation of the metered quantity and application duration of protective medium 14, not shown in more detail, takes place by means of the control station or the machine control, taking into account the general operating conditions, in particular the substrate width, running speed of the machine, length of the print job and temperatures in the roller mill and in the cylinder group , the application of the protective medium and / or the doctoring of the mixture of protective medium and printing ink is controlled.
