Definitions

  • the invention relates to an irradiation tunnel according to the preamble of claim 1 and to a method for irradiating containers in the irradiation tunnel.
  • Containers are increasingly printed directly in bottling plants using UV-reactive inks.
  • the finished but not sufficiently cured printed images are preferably aftertreated with broadband UV radiation in UVC, UVB and UVA and the inks thereby rapidly and completely cured.
  • broadband UV radiation for example, mercury vapor lamps in question.
  • the lamps are arranged one behind the other in an irradiation tunnel along a transport means in the transport direction in order to irradiate the containers laterally and to cure existing UV-curing inks (inks).
  • the irradiances required for the curing cause considerable heating of the irradiation tunnel, which has been counteracted by suction of existing air in the irradiation tunnel and Nachsprömen cooler ambient air through the container inlet and the container outlet.
  • air cooling inside the irradiation tunnel has two fundamental disadvantages.
  • the heat exchange is so severely limited by the range of practicable volume flows on the affected surfaces that lamps can always be arranged only on one side of the means of transport and on the other side cooling zones without lamps are needed.
  • a two-sided irradiation of the containers is usually required, at least two zones, each with one-sided irradiation and associated cooling zones, must be arranged one behind the other along the transport means. This leads to an undesirably elongated design of the irradiation tunnel.
  • the air cooling is based on the intake of comparatively large volumes of air through the container inlet and the container outlet. Since the air sucked in can hardly be filtered, dust is introduced into the irradiation tunnel with the air in the room. This causes undesirable contamination of the irradiation tunnel and possibly also the container.
  • the irradiation tunnel comprises a transport means for containers, along the transport means arranged lamps for UV irradiation of the containers and a cooling device for the interior cooling of the irradiation tunnel.
  • the cooling device comprises liquid-cooled heat sinks which extend into irradiation areas of the lamps.
  • the heat sinks are at least partially irradiated by opposing lamps.
  • the liquid-cooled heat sink allow a more compact design of the irradiation tunnel, since both the heat sink and the lamps can be arranged directly next to each other and on both sides of the transport.
  • supply air through the container inlet and / or the container outlet of the irradiation tunnel is dispensable. Thus, contamination of the irradiation tunnel and the container with dust from the ambient air can be avoided.
  • the heat sinks are designed for dissipating energy, which was introduced by the lamps as radiant energy in the irradiation tunnel and is absorbed by the inner walls, components and the air present in the interior.
  • the interior cooling for cooling the lamps itself plays no or only a minor role.
  • the cooling of the lamps via known cooling systems, for example via separate air or water cooling circuits for the individual lamps.
  • the heat sinks have no radiation function in the sense of reflection and / or scattering of the UV light and / or emission of heat radiation after light absorption. Instead, the light energy absorbed therefrom and the thermal energy absorbed by convection from the interior air should be transmitted as comprehensively as possible to the cooling liquid flowing through the heat sinks.
  • the irradiation areas are areas that are directly irradiated by the lamps, possibly also intermittently through the transport gaps between the moving containers.
  • the lamps are arranged on both sides of the transport means, and the heat sinks are, viewed transversely to the transport direction, formed at least between the lamps, in particular around the lamps.
  • the range of lamps can be laterally of the transport for effective cooling of indoor air and for the absorption of Radiation energy can be used. This allows a particularly compact irradiation tunnel.
  • liquid-cooled heat sinks are formed above the transport means.
  • the heat sinks can then be designed essentially in the form of a ceiling of the irradiation tunnel in order to absorb scattered radiation and to cool interior air rising upwards.
  • These heatsinks are usually outside of the irradiation areas.
  • the liquid-cooled heat sinks may for example comprise a total area of at least 0.5 m 2 and in particular of at least 1 m 2 , wherein the total cooling surface is a cooling surface in contact with the interior air.
  • the heat sinks preferably comprise hollow plates made of metal, in particular of an aluminum alloy.
  • Such hollow plates allow an equally mechanically stable enclosure of the transport path for the container as well as an effective heat transfer to the cooling liquid, which is in particular cooling water.
  • the hollow plates have cooling channels which can be connected in parallel and / or in series between the flow and return in a flexible manner in order to optimize the cooling capacity in individual regions of the irradiation tunnel.
  • Aluminum alloys are particularly suitable for the production of hollow plates and can be easily anodized, for example.
  • the heat sinks are preferably UV-light-absorbing coated and / or anodized, in particular with a mean absorption coefficient ⁇ of at least 0.5 in the spectral range from 200 to 450 nm. In this way, incident radiant energy can be effectively removed from the irradiation tunnel and consequently minimize the heating of indoor air.
  • the irradiation tunnel further comprises at least one ventilation duct for blowing in supply air.
  • at least one ventilation duct for blowing in supply air.
  • supply air with controlled supply of supply air, convection in the irradiation tunnel can be forced to favor a constant heat exchange of the indoor air and the heat sinks.
  • Supply air with a suitable quality can be specifically supplied via the ventilation duct.
  • the transport means is a conveyor belt for the stationary transport of the containers, and the ventilation channel opens below the conveyor belt in the irradiation tunnel.
  • the irradiation tunnel further comprises a fan supplying the ventilation duct and a suction for exhaust air from the irradiation tunnel, wherein the fan is designed at least for complete replacement of the extracted exhaust air.
  • the injected supply air could have a larger volume flow than the suctioned exhaust air, so that excess supply air flows through the container inlet and / or container outlet to the outside. An entry of dust from the ambient air into the irradiation tunnel can thus be counteracted even more effectively.
  • the lamps are separately cooled UV lamps for curing UV-curing inks (inks) on the containers.
  • the lamps thus have sufficient radiation power for the curing of the printing inks. Due to their independent cooling, the UV lamps do not significantly affect the interior of the irradiation tunnel with electrical power loss.
  • the stated object is also achieved with a direct printing machine for containers, comprising printing units for printing UV-curable ink (ink) on the containers and a downstream of the printing units for UV curing of the ink arranged irradiation tunnel according to at least one of the embodiments described above.
  • a direct printing machine for containers comprising printing units for printing UV-curable ink (ink) on the containers and a downstream of the printing units for UV curing of the ink arranged irradiation tunnel according to at least one of the embodiments described above.
  • the containers are then transported in a constant rotational position through the irradiation tunnel, and the lamps irradiate the containers on both sides and in particular fully.
  • UV-curable printing inks (inks) can thus be cured on a comparatively short transport path to an extent suitable at least for further processing and handling.
  • the containers are then transported at a clear distance from each other, which is at least twice as large as the largest dimension of the container in the transport direction.
  • radiation emitted obliquely by the lamps can fall to a sufficient extent on wall sections which are oriented in (or approximately in) the transport direction or in the opposite direction.
  • a full cure of UV reactive inks (inks) or the like is possible.
  • air in the irradiation tunnel sweeps along the heat sinks as a result of, in particular, forced air convection, and in the process releases heat energy to a cooling liquid flowing through the heat sinks.
  • Air convection can be forced, for example, by controlled supply air and / or the transport movement of the containers. The heat energy thus absorbed by the heat sinks is effectively and controllably carried away by the cooling liquid.
  • the liquid-cooled heat sinks preferably absorb treatment radiation and, in particular, radiation incident directly from the lamps.
  • the treatment radiation drops, for example, by the existing in the transport direction between the containers transport gaps on the heat sink.
  • the cooling bodies also receive directional and / or diffuse reflections, for example after reflection at the containers. The energy dissipated by light absorption is extracted directly from the irradiation tunnel and thus can no longer contribute to the heating of the interior air in the irradiation tunnel. This leads to a particularly efficient interior cooling of the irradiation tunnel.

  • second liquid-cooled cooling bodies 6 are preferably present in the form of a lateral border of the transporting means 3. These heat sinks 6 can also lie at least partially in the irradiation areas 4a of the lamps 4.
  • At least a third liquid-cooled heat sink 7 in the form of an intermediate ceiling or the like above the transport 3 and the containers 2 is present.

  • recesses 5a are then formed for the lamps 4.
  • first heat sinks 5 of intersecting columns 5b and longitudinal beams 5c can be assembled in a segment-like manner around the recesses 5a, as illustrated for the purpose of illustration only on the right-hand side of FIG.

As the cooling liquid 9, water supplied under conventional line pressure is suitable. As can also be seen from FIG. 1, the lamps 4 are cooled separately, for example by means of closed air cooling circuits 10 (indicated only schematically on the right). These lead electrical power loss of the lamps 4 and possibly also immediately before the lamps 4 resulting ozone or the like. The first heat sink 5 have no or only minor importance for the loss-related cooling of the lamps 4.

  • the volume flow of the supply air 14 is slightly smaller than the volume flow of the exhaust air 16, for example by at most 5%, so that a small amount of air flows through the container inlet 17 and the container outlet 18 into the irradiation tunnel 1.
  • An entry of dust from the ambient air can thereby reliably avoid and at the same time an escape of ozone from the irradiation tunnel 1.
  • Omitted ozone leads to unpleasant odors, even if the occupational exposure limit has not yet been reached.
  • the ventilation duct 12 preferably opens below the transport means 3 in the irradiation tunnel 1.
