Definitions

  • the invention relates to a device and a method for cleaning a central impression cylinder of a flexographic printing machine according to the preambles of claims 1 and 8.
  • Contamination occurs again and again in flexo printing machines, especially due to the low-viscosity printing ink. Soiling occurs, for example, due to paint splashes, incorrectly set ink transfer cylinders or also due to web breaks. Foreign particles such as dust, dry ink particles or even insects can also be drawn into the gap between the substrate and the impression cylinder.
  • the object of the present invention is therefore to propose a device and a method for cleaning a central impression cylinder of a flexographic printing press, with which the disadvantages described above can be avoided.
  • At least one nozzle is provided, from which gaseous and / or liquid carbon dioxide can be led out in an exit direction, the exit direction being directed towards the impression cylinder and wherein the nozzle - seen against the direction of rotation of the impression cylinder - between the line of contact of a printing material web and the release line of the printing material web is arranged.
  • the nozzle serves to provide a narrowing in the direction of movement of the carbon dioxide in order to accelerate the carbon dioxide molecules.
  • the carbon dioxide is already passed through the nozzle at a higher pressure than the ambient pressure. Acceleration causes the carbon dioxide to expand at least in part after it leaves the nozzle and there it passes directly from the gaseous or liquid phase to the solid phase, that is to say it is sublimed or solidified. These solid particles are now able to lift, reduce or soften the contamination from the central impression cylinder, so that the contamination can be removed in an optional further step.
  • the nozzle also has the effect that the jet comprising the carbon dioxide can be directed onto the impression cylinder.
  • the often occurring sublimation effects can increase the cleaning effect.
  • the particles pass through the phase transition from solid to liquid, which is particularly associated with an increase in the volume of the particle in question.
  • the increase in volume creates an additional pressure surge, which can also help to loosen dirt particles.
  • this nozzle and the necessary feed and / or discharge lines are small. It is therefore provided according to the invention that this nozzle - seen against the direction of rotation of the impression cylinder - is arranged between the line of contact of the printing material web and the peeling line of the printing material web. It is therefore not necessary to remove the printing material web at least from areas of the central impression cylinder.
  • the printing material web is printed in flexographic printing machines when it rests on the impression cylinder.
  • the printing material web is placed on the impression cylinder by means of a roller or roller, often referred to as a pressure roller.
  • the printing material web can now pass through one or more printing units until it is lifted off the impression cylinder along a release line.
  • a guide roller is provided, which, however, does not form a common nip with the impression cylinder.
  • the wrap angle of the printing material web is often at least 270 degrees, in particular at least 300 degrees.
  • the combination of the compact design and the low-residue cleaning means that the impression cylinder can also be cleaned while a print job is being carried out. This not only leads to cost reductions since the downtimes of the printing press are reduced, but also to better print quality, since contamination of the printing material is avoided. Another advantage is that the surface of the central impression cylinder is protected since no mechanical contact of a cleaning device - as is known from the prior art - with the impression cylinder is necessary.
  • the carbon dioxide can be led out of the nozzle by means of a carrier fluid, in particular by means of a carrier gas.
  • a carrier fluid in particular by means of a carrier gas.
  • the consumption of carbon dioxide can be reduced.
  • Normal air can be used as the carrier gas.
  • the carbon dioxide only has to be added before it passes through the nozzle, a slight overpressure being sufficient.
  • the carrier gas is under a pressure of at least 5 bar, preferably at least 6 bar.
  • the compressed air connections which are often present anyway, can thus be used to provide the pressurized carrier gas.
  • a suction device is provided with which the carbon dioxide and / or contamination particles can be removed.
  • this suction device can comprise a suction nozzle which is arranged in the vicinity of the above-mentioned nozzle in order to be able to carry out the suction where it is necessary.
  • the suction nozzle is also arranged between the line of contact and the release line of the printing material web
  • the nozzles have an oval or round outlet cross section. Rectangular cross sections can also be used be beneficial.
  • the outlet cross section preferably has a diameter or a side length of at least 1 mm and at most 100 mm. In this way, a good cleaning effect can be achieved, since a sufficiently large irradiation area is achieved both in the direction of rotation of the counter-pressure cylinder and transversely thereto. It is also advantageous if the outlet of the nozzle is at a distance of at least 10 mm, in particular at least 20 mm, from the surface of the impression cylinder, measured in the direction of the main axis of the nozzle. The distance of the nozzle from the surface of the impression cylinder, however, should not exceed 100 mm, preferably not 80 mm.
  • the main axis of the nozzle and the surface of the impression cylinder form an angle of 45 degrees to 135 degrees to one another.
  • the nozzle radiates perpendicular to the impression cylinder or with a deviation of up to 45 degrees from the vertical direction.
  • a particularly good cleaning effect can be achieved since the carbon dioxide is then concentrated on a comparatively small area.
  • the main axis of the nozzle is inclined against the direction of rotation of the counter-pressure cylinder. In this way, an effect is achieved that is comparable to a scraping effect of a knife.
  • the nozzle is arranged movably, in particular displaceably, on a linear axis which extends transversely to the direction of transport of the impression cylinder.
  • the nozzle is arranged on a carriage and that the traverse is designed as a rail. It can be advantageous if the nozzle can be moved by a motor by means of a drive device. In this embodiment, a single nozzle or a small number of nozzles can be provided which can be moved in a targeted manner at positions at which contaminants are to be removed. Sufficient cleaning can thus be achieved with an inexpensive device for cleaning a central impression cylinder of a flexographic printing machine.
  • the nozzle On the extension of the side edges of the printing material web during a running print job.
  • ink splashes hit the impression cylinder in the area of the edge of the printing material web.
  • the proportion of these ink splashes that is not carried along by the printing material web adheres to the impression cylinder and could lead to problems in the long run.
  • the provision of at least two nozzles can be advantageous in order to be able to assign a nozzle to each side edge of the printing material web. Immediate removal of dirt is then possible without first having to move a single nozzle.
  • a printing press that includes a device for detecting the side edges of the printing material web to pass on the information on the position of the side edges to a control device that controls the drive device for positioning the nozzle transversely to the impression cylinder. Automation can thus be created with which the areas of the side edges on the impression cylinder can be cleaned automatically.
  • a sensor device is provided with which contamination can be detected.
  • electromagnetic radiation for example visible light
  • the intensity of the reflected light can now be measured, in particular the spectral intensity.
  • the cleaning device can be controlled in particular with regard to the position and also with regard to the cleaning intensity.
  • the sensor device similar to that described above, and the nozzle itself, can be moved at least transversely to the counter-pressure cylinder, so that the sensor position can be adjusted so that the points of the supposedly greatest contamination can be examined.
  • the sensor device can also be adjusted with regard to their position by the device for detecting the side edge of the printing material web.
  • the control device mentioned can also accomplish this task.
  • such a sensor device can be used while the printing presses continuously print on the printing material web (so-called continuous printing). In this case, if a contamination is detected, cleaning can be carried out as required, which reduces the use of consumables.
  • the present invention can also be used in an inline printing unit, which is preferably also designed as a flexographic printing unit, or in a gravure printing unit.
  • the impression cylinder of an intaglio printing unit is usually referred to as an impression roller.
  • Other cylinders of a printing press can also be cleaned with the present invention.
  • the pressure roller which is in contact with the impression cylinder and is therefore particularly susceptible to contamination, should be mentioned in particular.
  • Fig. 1 shows a flexographic printing machine 100 with a central impression cylinder 101, over which a printing material web 102 can be guided.
  • the printing material web 102 is preferably first guided in the transport direction T via at least one guide roller 103. This is followed by a pressure roller 104, with which the printing material web 102 is pressed onto the peripheral surface of the impression cylinder 101.
  • the impression cylinder 101 rotates in the direction R, so that the printing material web is guided past several — four are shown — inking units 105, 105 ', 105 "and 105'".
  • such an inking unit 105 comprises a format cylinder 106, which bears the print motif.
  • the necessary printing ink is applied by the inking roller 107, usually an anilox roller, to the printing motif of the format cylinder 106, which in turn applies this printing ink to the printing material 102 in a manner appropriate to the motif.
  • Each inking unit usually prints with a different color.
  • the printing substrate 102 After passing the last inking unit 105 '", the printing substrate 102 leaves the impression cylinder 101 on a common tangent of the impression cylinder 101 and the guide roller 108.
  • the point of contact of this tangent with the impression cylinder thus represents the line of detachment of the printing material web from the impression cylinder.
  • the area between this common tangent and the pressure roller 104 is the web-free area, which is represented by the double arrow 110.
  • a nozzle 120 according to the invention explained throughout the description is arranged in this non-web area.
  • the Figure 2 now shows further details for cleaning the impression cylinder 101, which rotates in the R direction.
  • the printing material web 102 is shown, which can be placed on the impression cylinder 102 by means of a pressure or pressure roller 104.
  • the separation line of the printing material web from the impression cylinder is not shown in this figure.
  • the nozzle 120 receives the carbon dioxide and / or the carrier fluid via a feed line 121, which can be configured, for example, as a hose. Due to the narrowing cross section of the nozzle in the direction of flow of the gas or the carrier fluid, the carbon dioxide is accelerated in the direction of arrow 122 onto the counter-pressure cylinder in order to loosen contaminants.
  • the nozzle 120 is arranged on a carrier 132, preferably via a swivel joint 133.
  • a swivel joint can enable an angular adjustment of the nozzle 120 and thus the direction 122 relative to the impression cylinder.
  • the carrier is preferably held on a slide 130, which can be movable along the linear axis 131.
  • the linear axis preferably extends parallel to the axis of rotation of the impression cylinder and can be fastened, for example, to the machine frame of the printing press, not shown.
  • the carriage In order to enable the carriage to be displaced along the linear axis, it can be designed, for example, as a pneumatic double-stroke cylinder. Alternatively, the linear axis and slide can be designed as a linear motor. Another possibility would be a spindle drive for the carriage, the spindle then being able to be driven by a stationary drive, preferably by an electric motor.
  • a position sensor can be provided, by means of which the transverse position of the nozzle can be determined. Such a position sensor is important in connection with an automatic cleaning function.
  • at least one contamination sensor which is not shown, can additionally be provided, in order to be able to determine contamination of the impression cylinder.
  • a control device which receives a contamination signal from the contamination sensor, can now position the nozzle by moving the carriage relative to the contamination.
  • a suction device 140 is additionally shown, with which in particular the dirt particles detached from the impression cylinder can be reliably extracted from the surroundings of the impression cylinder, which is represented by arrow 141.
  • the suction device can be connected to a vacuum source via line 142.
  • the suction device 140 can extend in the transverse direction over the entire width of the impression cylinder. Alternatively, it can be made smaller, so that it essentially covers an area that the carbon dioxide emerging from the nozzle also reaches. In this case it can be provided that the suction device is also connected to the slide 130 via holding elements in order to enable simultaneous displacement with the nozzle 120.
