Definitions

  • the invention relates to a processing machine with a drying device, in particular a printing material or sheet processing or substrate processing machine, especially a printing press, and a method for operating a drying device in a processing machine.
  • UV emitters installed in a UV module on printing material processing machines are cooled during operation. Cooling of a UV radiator is also necessary at higher outputs so that it does not reach the transformation temperature of the glass tube and thus sags or even puffs up.
  • Exhaust air cooling systems for cooling UV radiators are known. Ambient air flows past the UV emitter through an air inlet opening in the housing, with the air inlet opening also being the radiation outlet opening.
  • the disadvantage is that the UV radiator, as a result of the structural design, is primarily cooled on the top.
  • the underside is generally significantly hotter, as there is insufficient convection. The heat dissipation on the underside takes place in addition to heat radiation through heat conduction from the glass tube to the well-cooled top.
  • an irradiation device wherein the radiation source in the irradiation device is arranged to be rotatable about its longitudinal axis in connection with an intake air cooling system.
  • the disadvantage of this solution is that it works with an intake air cooling system and has moving parts that are prone to failure, making it complex and uneconomical.
  • a UV irradiation device in which a first flow of cooling air is sucked into the housing on the sides via air inlet openings in the outer wall in order to cool the bulkhead system from the outside.
  • the cooling air is routed along the housing wall into a central suction duct and from there, via a collector, to a fan that promotes the entire flow of cooling air for the UV irradiation device.
  • a second flow of cooling air is collected in the area of the radiation source by a long-necked suction duct and fed into the collector via a throttle.
  • a disadvantage of this solution is that this exhaust air cooling does not adequately cool the underside of the radiation source.
  • the DE 102 47 464 A1 shows a dryer device with an infrared radiator, with a main dryer assembly being arranged downstream of an after-dryer assembly.
  • the dryer device is sealed off from cold ambient air.
  • an ultraviolet curing apparatus using a UV ray tube is known.
  • the distance between the reflectors and the radiator is adjusted via the length of the radiator.
  • an air pipe is used, which directs cooling air directly onto the radiator.
  • the cooling air discharged from the air duct is configured to increase in amount as it is farther from an exhaust side.
  • FIG. 12 shows a cooling apparatus for an ultraviolet lamp using blown air to cool substrate in order to prevent in advance damage that may be caused by malfunction of the shutter members of the housing.
  • the object of the invention is to create an alternative processing machine with a drying device or an alternative method for operating a drying device in a processing machine.
  • the cooling on preferably high-performance dryers in processing machines, such as substrate or printing material processing machines should be improved.
  • the cooling of a UV radiator should also be further improved on the underside.
  • the object is achieved by a device having the features of the independent device claim and a method having the features of independent method claim solved.
  • Advantageous configurations result from the dependent claims, the description and the drawings.
  • the invention has the advantage that an alternative processing machine with a drying device or an alternative method for operating a drying device in a processing machine is created.
  • the cooling on preferably powerful dryers in processing machines, such as substrate or printing material processing machines, in particular printing presses or sheet processing machines, is improved.
  • the cooling of a UV radiator on the underside is also particularly preferably further improved.
  • the drying device is preferably used in a sheet-processing or substrate-processing machine, especially a printing press, or such a machine is equipped with one or more such drying devices.
  • the drying device can preferably also be used optionally as an intermediate dryer or as a final dryer, for example in a delivery.
  • a tabular substrate for example sheet metal, can be processed as the substrate.
  • material in rolls or sheets can also be processed, in particular printed or painted.
  • a particular advantage of exhaust air cooling is that ozone generated by UV radiation is simultaneously extracted from the drying device, for example a UV module.
  • ozone is harmful to human health, on the other hand, ozone absorbs UV radiation and thus reduces the curing effect of the drying device, in particular the UV module.
  • a blown air system results in improved air flow with the favored exhaust air cooling.
  • Ambient air is preferred, in particular that which is outside of the drying device or that is in contact with a printing material Ambient air, guided in a targeted manner by additional directed air and/or blown air in such a way that both the ambient air and the additional air or blown air are optimally guided as cooling air around the radiation source before the common cooling air is removed as exhaust air through one or more air outlet openings, in particular sucked off , becomes.
  • the radiation source can be cooled indirectly and/or directly on the underside by air streams introduced on one side or preferably on both sides, for example blown air streams or blasted air jets, with the additional air, for example blown air, being introduced or blown in in particular outside the radiation area of a UV module .
  • air is preferably introduced or blown in on both sides, it can meet, for example, in the middle below the UV module or below the radiation source.
  • the radiation source in particular a UV emitter, can also be partly blown directly on from below.
  • blown air is guided parallel to or in the plane of the air inlet opening of the housing, so that the blowing device is not in the beam path of the radiation from the radiation source.
  • the blown air is thus preferably generated at least approximately parallel to the web of processing material or a web of printing material.
  • cooling air in the drying device in particular in the UV module, in an improved or optimized manner to the underside of the radiation source and the underside is therefore better cooled.
  • the cooling is advantageously more turbulent and, surprisingly, the upper side of the radiation source is also cooled better, which has been proven by investigations, specifically using temperature measurements.
  • a drying device for example the UV module, or the radiation source introduced or blown.
  • This can be done by air guiding elements, such as metal sheets, and/or blown air openings, in particular nozzles.
  • the air introduced or blown in on both sides can be either a partial mass or at least approximately all of the cooling air discharged in the UV module.
  • the air volume flow of the air that is additionally introduced or blown in by the blast air system can preferably be between 20% and 50% of the total cooling air volume flow. Accordingly, the proportion of inflowing ambient air can be between 80% and 50%. In particular, a ratio of at least approximately 1/3 of air that is additionally introduced or blown in by the blast air system and of at least approximately 2/3 of inflowing ambient air is sought.
  • the radiation sources in particular UV emitters, can thus be operated particularly advantageously with even higher power or the air mass flow can be reduced with the same cooling. Another advantage is that a bending or blowing up of a UV radiator can be avoided more reliably.
  • the blown air system is designed as an add-on module or additional module, which can be designed to be detachably or non-detachably connectable to a UV module of a dryer.
  • the blown air system can be designed to be placed on any UV module of a dryer.
