Definitions

  • the invention relates to a combined dampening inking unit for offset printing units, with applicator rollers that can be set on the plate cylinder, of which the first applicator roller, viewed in the direction of rotation of the plate cylinder, is connected to the next applicator roller via an oleophilic intermediate roller and of which the second and third applicator rollers and possibly the following applicator rollers are each in contact with an inking roller, also with a dampening roller of a dampening unit, which works together with the first applicator roller.
  • the ink film of an inking unit in offset printing units is known to absorb a certain amount of dampening solution via the plate.
  • the absorption of dampening solution depends on the nature of the ink and lasts until a color-dampening solution equilibrium is established in the inking unit: During the longer period of dampening solution absorption, the coloring, i.e. the delivery of ink to the plate, changes constantly.
  • the object of the invention is to ensure a quick establishment of the ink-moisture balance before the start of printing as well as the constant full operational readiness of the offset printing machine during printing interruptions, so that a minimal amount of waste is recorded. Furthermore, a better and more stable ink-moisture balance is to be achieved during the printing process.
  • the first applicator roller is adjustably mounted in three switching positions and is driven by frictional engagement and in that the first applicator roller rests in the three switching positions on the plate cylinder and / or on the dampening roller and / or on the intermediate roller.
  • the first applicator roller bears against the plate cylinder, friction roller and intermediate roller.
  • the first applicator roller can be applied to the dampening and intermediate rollers at the same time. If the plate is to be pre-moistened, the application roller is in contact with the dampening roller and the plate cylinder. If you want to keep the inking and dampening unit 1 separately ready for operation during longer printing interruptions, the contact of the first application roller with the dampening roller can also be interrupted when the application rollers are switched off, contact with the inking unit being established via the intermediate roller.
  • the oleophilic Intermediate roller for example a plastic-covered steel roller, also causes the first applicator roller to transfer not only dampening fluid, but also some ink to the plate. Viewed in the direction of rotation of the plate cylinder, the proportion of ink transferred from each subsequent applicator roller increases, while the proportion of dampening fluid decreases.
  • the constant balancing of dampening solution and ink via the intermediate roller as well as the application of ink and dampening solution in the above-described graded manner cause the ink to lie better on the paper, ie the print appears more brilliant.
  • the constant flow of dampening solution and ink over the intermediate roller makes the dampening insensitive to the influence of the plate cylinder channel and to the division of printing and non-printing areas given for a specific print job.
  • a combined dampening inking unit is already known from US Pat. No. 3,433,155, the dampening roller of which, which is fed by an immersion roller via a metering roller, cooperates with the first applicator roller. Since the dampening roller and metering roller have the same direction of rotation in their setting zone, the latter two rollers must be arranged one above the other because of the backflow of the dampening solution from the gap between the immersion and metering rollers. As a result, the surface area of the measuring roller which is of interest for the dampening is withdrawn from a visual inspection.
  • An advantageous embodiment of the invention is characterized by such a choice of the transmission ratio of the metering and immersion roller, which is in frictional engagement, relative to the transmission ratio of that of the journal of the immersion roller guided gear drive of the metering roller that the peripheral speed of the metering roller is slightly greater than that of the plunger. This causes the driving flanks of the gear drive of the metering roller to be in constant contact. The slippage that occurs between the dipping roller and the metering roller advantageously cleans the jacket of the dipping roller.
  • the intermediate roller that works with both the first and the second applicator roller is arranged such that it can be traversed. Traversing prevents ink build-up on the first application roller and stenciling by the application rollers.
  • All of the previously described embodiments of the invention can work according to a method for quickly adjusting the ink-moisture balance and for balanced inking and moistening of an offset printing plate during production, which has the method steps indicated in claim 11.
  • An offset printing machine put into operation and operated according to this process produces practically no waste.
  • the method according to the invention can be advantageously modified in that the first application roller remains on the plate when the pressure is briefly interrupted, while the other application rollers are stopped and the intermediate roller is lifted off the first application roller, and by switching the machine to production printing the working method in the Stage overwetting the plate.
  • Another preferred development of the method according to the invention provides that in the event of a prolonged interruption in printing, the first applicator roller both from the plate and from the dampening roller ze is turned off and placed on the intermediate roller and that after switching the machine to production, the working process begins at the pre-moistening stage of the inking unit.
  • the arrangement according to the invention of the combined dampening inking unit also allows the rollers, including even the metering roller, to be washed without the plate being wetted.
  • the dipping roller is excluded from the washing process.
  • the individual steps of the washing process according to the invention consist in lifting the metering roller from the immersion roller when washing the combined dampening inking unit, the metering roller drive gearwheel being separated from the immersion roller drive and the position of the other rollers corresponding to that of the pre-wetting of the combined dampening inking unit.
  • the washing process can only be initiated if the metering roller drive gear is separated from the dip roller drive.
  • the embodiment shown in FIGS. 1 to 9 of a combined dampening inking unit according to the invention has five applicator rollers 1 to 5, which can be placed on and can be removed from the plate cylinder 6.
  • the first application roller 1 seen in the direction of rotation of the plate cylinder 6 is connected to the next application roller 2 via an intermediate roller 7.
  • the application rollers 2 and 3 are in contact with an inking roller 8 and the last two application rollers 4 and 5 with an inking roller 8 '.
  • the inking train is provided with other rollers, not shown, in a known manner.
  • the first applicator roller 1 is supplied with dampening solution by means of the dipping roller 9 via the metering roller 10 and the inking roller 11 which works together with the applicator roller 1.
  • the dipping roller 9 is immersed in the dampening solution 12 of the dampening solution box 13.
  • With the dampening roller 11 can also work together a storage roller 14 shown in dashed lines, which is, however, only provided for certain printing work.
  • the five application rollers 1 to 5 have a colorful, elastic surface.
  • the outer surface of the intermediate roller 7 is also oleophilic. For example, it can consist of Rilsan.
  • the lateral surface of the two inking rollers 8 and 8 ' is designed in the same way.
  • the dampening roller 11 has an electrolytically roughened chrome surface, whereas the metering roller 10 has a rubber jacket.
  • the outer surface of the dipping roller 9 in turn consists of an electrolytically roughened chrome layer.
  • the storage roller 14 whether in an alcohol or in a normal dampening system, it is either provided with a rubber jacket or with a textile cover.
  • the storage and setting means of all rollers correspond to the designs generally known in printing technology.
  • the three friction rollers 7, 8 and 11 are positively driven, the five application rollers 1 to 5 and the intermediate roller 7, however, only by means of friction.
  • the dipping roller 9 can be driven directly by a separate motor 15 with a peripheral speed that is variable in relation to the peripheral speed of the plate cylinder 6.
  • a spur gear 17 is provided on one of the two journals 16 of the plunger roller 9, which sprocket 18 is connected to a further spur gear 18 combs, which is located on one of the journal 19 of the metering roller 10.
  • the metering roller 10 is thus driven practically at the same peripheral speed as the dipping roller 9.
  • the transmission ratio of the metering and immersion roller, which is in frictional engagement, relative to the transmission ratio of the gear drive 17, 18 of the metering roller 10 derived from the journal 16 of the immersion roller 9 is selected such that the peripheral speed of the metering roller 10 is slightly greater than that of the immersion roller 9. This ensures that the driving flanks of the spur gear 17 always rest on the tooth flanks of the driven spur gear 18 on the journal 19 of the metering roller 10.
  • the dipping roller 9 is mounted stationary.
  • the metering roller 10, on the other hand, is arranged such that it can be set at a distance from the dipping roller.
  • the gap or the contact pressure in the setting zone between the dampening roller 11 and the metering roller 10 can be adjusted by adjusting the latter roller.
  • Applicator roller 1 is arranged so that it can pivot about the axis of rotation of the dampening roller 11 via the bearing bracket 20.
  • the pivoting causes a switching cam 21, which is actuated by a step circuit, not shown, and which cooperates with a switching lug 22 of the bracket 20.
  • Adjustable compression springs 23 exert such a force on the bearing bracket 20 that the switching lug 22 is always pressed in the direction of the switching cam 21.
  • the application roller 1 is mounted eccentrically in the bearing brackets 20, such that the outer surface of the application roller 1 is separated from the outer surface of the dampening roller 11 about the gap 25 by pivoting a roller lever 24.
  • the lifting of the application roller 1 from the dampening roller 11 causes a roller 26, which is located on the roller lever 24, and which has fallen into a recess 27 of a control cam 28 in this sound position.
  • the control cam 28 is mounted coaxially to the dampening roller 11 and pivotably with the bearing brackets 20.
  • the intermediate roller 7 and the application roller 2 are rotatably and adjustably mounted on common bearing brackets 29. They are arranged to be pivotable about the axis of rotation of the inking roller 8.
  • An adjusting lug 30, which is firmly connected to the bearing brackets 29, is pressed against a switching cam 32 by a compression spring 31.
  • the application roller 2 can be lifted from the plate cylinder 6 around the gap 33.
  • the intermediate roller 7 is also pivoted through the same angle.
  • the intermediate roller 7 is mounted in the bearing brackets 29 in a spring-loaded manner by means of the compression springs 34, so that it can adjust itself to the individual positions of the two adjacent application rollers 1 and 2. In the switching position shown in FIG. 2, by the way, the application roller 1 is raised by the gap 35 from the outer surface of the plate cylinder 6 by actuating the switching cam 21.
  • the roller position according to FIG. 2 corresponds to the first switching stage.
  • the main switch is turned on.
  • the power supply of all operating points is ensured.
  • the dampening solution circulation has started operation.
  • the motor 15 drives the immersion roller 9 and the metering roller 10 at an increased speed, for example at 200 revolutions / min.
  • the main engine is not yet on. Therefore, the plate cylinder and all other rollers of the combined dampening ink unit are still still.
  • the pre-humidification takes place th of the dampening unit part consisting of the submersible roller 9 and the metering roller 10. After this selectable time period of, for example, 3 seconds, the dipping roller speed is reduced to 10 revolutions / min. The dampening unit is ready for use.
  • the main motor is started automatically after the start-up warning signal.
  • the plate cylinder 6 and the illustrated rollers 11, 1, 7, 2 and 8 as well as the other rollers (not shown) of the combined dampening inking unit begin to rotate.
  • the direction of rotation of the friction roller 11 is such that it is opposite to the direction of rotation of the metering roller 10 in the setting zone.
  • a tap-changer not shown, has pivoted the bearing bracket 20 slightly further clockwise over the switching cam 21 and the switching lug 22.
  • the roller 26 has come out of the recess 27 of the control cam 28 and has applied the applicator roller 1 to the dampening roller 11.
  • the applicator roller 1 comes into contact with the intermediate roller 7.
  • the inking unit In this switching position of all rollers, the inking unit is pre-moistened. During an adjustable period of 0 to 5 seconds, a fountain solution stream flows from the immersion roller 9 via the intermediate roller 10, the dampening roller 11, the application roller 1 and the intermediate roller 7 into the inking unit part of the combined dampening inking unit. At the same time, some ink passes from the inking unit part to the first applicator roller 1 via the intermediate roller 7.
  • the pre-moistening continues until the inking unit strand of the combined dampening inking unit is saturated with dampening liquid, ie until the ink and fencing agent have reached a state of equilibrium which means that each one is constantly printing.
  • the first applicator roller has the greatest distance from the Surface of the plate cylinder 6 reached. This distance is indicated by the gap 36.
  • the other application rollers 2 to 5 have not changed their position.
  • the immersion roller 9 and the metering roller 10 rotate at an increased speed, for example at 200 revolutions / min.

  • the position of all the rollers remains unchanged.
  • the speed of the dip roller 9 and metering roller 10 is increased again for an adjustable period of time, for example 0 to 5 seconds, z. B. to 200 revolutions / min, so that a larger amount of dampening solution is supplied to the plate for a short time. This stage is therefore called "over-moistening the plate".
  • the speed of the submersible 9 and metering roller 10 is regulated down again and the speed is adapted to the machine speed.
  • the automatic tap changer now ensures the automatic regulation of the speed of the motor 15 and the switching on of the other application rollers 2 to 5, as can be seen from FIG. Since both the inking unit part of the combined dampening inking unit and the plate have been pre-moistened to the state that prevails during the printing process, there is no waste during the paper run synchronized with the application rollers being turned on.
  • the offset printing unit is fully operational. There is no change in color.
  • the peculiar arrangement of the rollers namely the contact of the first application roller with the dampening roller 11 and the intermediate roller 3, means that the first application roller 1 primarily applies dampening solution 12 but also to a lesser extent ink to the plate, while the next application rollers 2 to 5, Depending on their distance from the first applicator roller, less dampening solution, but more ink on the plate.
  • the bridging intermediate roller 7 now ensures that this ratio of the graded application of ink and fountain solution is maintained, so that, as tests have shown, the ink lies excellently, i. H. there is a brilliant pressure.

  • These set screws 42 and 43 are arranged approximately at an angle of 900 to one another.
  • By actuating the adjusting screw 42 the gap or contact pressure in the setting zone between the dampening roller 11 and the metering roller 10 is set.
  • An adjustment of the adjusting screw 43 changes the contact pressure between and / or the immersion roller 9 of the metering roller 10.
  • the axle journals 19 of the metering roller 10 are provided with a positioning surface 44.
  • the footprint 44 can come into contact with the set screw 43.
  • the metering roller 10 is lifted off the dipping roller 9 by means of the force of the compression spring 41.
  • the adjustment of the desired or required wet film is greatly facilitated by the fact that the lateral surface part of the metering roller 10 which follows the squeezing gap between the immersion roller 9 and the metering roller 10 can be seen well from above.
  • the operator can press the production button and the start-up process of the machine starts at the "over-moistening of the pressure plate" stage, ie. that is, the speed of the dip roller 9 and the metering roller 10 is briefly increased again by increased drive from the motor 15 to about 200 revolutions / min, so that the plate is briefly over-moistened, whereupon, as already described above, the downward regulation of the dip - And metering roller speed to the machine speed and the other application rollers are synchronized with the paper run, of course, the intermediate roller 7 is brought back into contact with the first application roller 1.
  • the operator wants to start the machine again at the end of the long interruption, he only needs to press the push button and the step switches mentioned ensure that the entire start-up procedure is carried out automatically, i.e. , First the dampening unit part, then the inking unit part and then the plate are pre-moistened and finally the plate is briefly over-moistened before the other applicator rollers are switched on.

  • the switching stage "pre-dampening inking unit" For the washing of the combined ink dampening unit, as shown in FIG. 9, the switching stage "pre-dampening inking unit" must be set.
  • the journals 19 of the measuring roller 10 must be rotated by hand in such a way that the positioning surface 44 faces the adjusting screw 43, as a result of which the metering roller 10 is lifted off the plunger roller 9 by the gap 45.
  • the spur gear 17 fastened to the journal 16 and the spur gear 18 attached to the journal 19 also come out of engagement.
  • the motor 15 now drives the immersion roller 9 at a low speed, for example 10 revolutions / min.
  • the metering roller 10, on the other hand is set somewhat more strongly against the dampening roller 11 by a special position of the adjusting screw 42.
  • This particular position of the adjusting screw 42 is that its axis of symmetry does not coincide with it covers the connecting line between the axis of rotation of the metering roller 10 and the axis of rotation of the dampening roller 11 in both normal operating positions, but deviates slightly therefrom, so that when the metering roller 10 is switched off by the dipping roller 9, a greater pressure is generated in the setting zone between the metering roller 10 and the dampening roller 11 .
  • the roughness of the chrome surface of the dampening roller 11 is sufficient to drive both the metering roller 10 and the applicator roller 1 with intermediate roller 7 during the washing process which is now starting. It must be mentioned that the washing process can only be started when a rotary switch (not shown) is actuated by rotating the axle pins 19 into the position shown in FIG. Since, as tests have shown, in spite of the hydrophilic character of the surface of the dampening roller 11 with the fountain solution film flowing back in the direction of the dampening solution box 13, ink particles reach the outer surface of the oleophilic metering roller 10 and are deposited there, washing of the metering roller 10 with all other rollers is necessary with the exception of the dip roller extremely advantageous.
  • Modifications of the illustrated embodiment of the invention are also conceivable.
  • the number of application rollers can be varied depending on the requirements.
  • the diameter of the intermediate roller can be made equal to or larger than that of the adjacent application rollers. This enables the drive means of the intermediate roller to be designed to achieve a large distribution stroke.
