Definitions

  • the invention relates to an irradiation device according to the preamble of claim 1 and uses of such.
  • Irradiation devices of this type or of a similar type are known from the prior art.
  • the DE 102 43 577 A1 also shows and describes a similar UV irradiation device, in which an adjustment of the controllable reflector is provided in a parallel or vertical shut-off position to the beam attachment surface of the (directly parabolic) directly associated with the radiation source.
  • a device for curing substances on a substrate which also has essential features of such an irradiation device and in particular provided reflectors are whose UV radiation source facing surface has different optical properties than the surface facing a carrier body.
  • the support structure of the housing is preferably formed from an aluminum extruded profile, and the reflectors are in particular screwed onto an actively cooled support body.
  • the invention is therefore based on the object of providing an improved, in particular quickly and effectively controllable and high durability having irradiation device of the generic type, which is also rational and inexpensive to produce.
  • the proposed irradiation device on two - preferably similar - radiation sources whose processing effective radiation is directed by a common, central controllable reflector in the operating state on the substrate to be acted, while the same reflector in a shutdown position, the radiation of both Keeps radiation sources away from the substrate.
  • the proposed solution offers, compared to known irradiation devices, a substantially increased flexibility in adapting to specific powers of about 15 W / cm up to about 240 W / cm.
  • a suitable reflector geometry results for many processing purposes by the interaction of two radiation sources, an optimal ratio between intensity and energy distribution on the substrate to be processed (in particular to be crosslinked or cured).
  • the radiation profile can in a simple manner by the geometry of the controllable reflector (deflecting mirror) in a Wide range can be changed without that other components of the irradiation device would necessarily have to be changed as well.
  • controllable reflector as a shutter (shutter), together with the customary in the case of shutdown reduction of the radiation power of the radiation sources, a temporally virtually unlimited standby operation.
  • the radiation sources, the controllable reflector and the housing are formed like an elongated profile. Furthermore, it is provided that the controllable reflector and / or the auxiliary reflectors and / or the end reflector sections have a curved reflector surface. It is understood that with a suitable curvature, especially of the partially parabolic or partially elliptical type, a substantially linear radiator can be mapped in a favorable manner to a large-area workpiece.
  • the radiation field generated on the substrate is particularly easy to predetermine. With separate controllability of the two radiation sources results in applications where only the power of a radiator is required, a doubled production use time of the irradiation device.
  • controllable reflector between the first and second position is rotatable and the drive means comprises a, in particular electromotive or pneumatic, turntable.
  • This design is particularly compact, which is of particular advantage in applications with little available space - such as in printing presses.
  • auxiliary reflector in the angular range around the radiation sources, not by reflector surfaces of the controllable Reflector is taken, depending at least one elongated, in particular wave-selective, auxiliary reflector is arranged, which directs processing radiation substantially to the controllable reflector out. If these auxiliary reflectors are wavelength-selective in such a way that their reflectivity for the actual processing radiation is higher than that for non-processing radiation components, in particular unwanted heat radiation, the thermal load of a sensitive substrate can be further reduced. However, a non-wavelength-selective design can also be considerably advantageous already for reasons of optimal energy utilization of the generated radiation.
  • an upper and lower auxiliary reflector to be provided in each of the spatial regions above and below the first or second radiation source, which in particular have a non-asymous approximate U-shape in cross-section.
  • each radiation source is associated with a Endreflektorabites.
  • controllable reflector and / or the auxiliary reflectors and / or the Endreflektorabitese each have at least one coolant channel for passing a cooling fluid.
  • Radiation sources of such high power are used in most large-scale industrial applications that active cooling of the most heavily irradiated device components is required for life reasons. In many cases, liquid cooling is required in this case, so that the coolant channels for a liquid coolant must be dimensioned and the connections made accordingly.
  • controllable reflector has at least one reflector surface which is detachably inserted into a support structure. This makes it possible in a simple manner to use a few types of support elements for various concrete geometric configurations and nevertheless to cover many applications by using differently shaped reflector surfaces.
  • the or each radiation source is fixedly assigned an auxiliary reflector, which likewise has at least one releasably inserted reflector surface, which directs the processing radiation substantially to the controllable reflector.
  • auxiliary reflector which likewise has at least one releasably inserted reflector surface, which directs the processing radiation substantially to the controllable reflector.
  • the separately manufactured and inserted in support elements reflector surfaces are metal sheets with defined by shaping and / or adjusting in the inserted state curvature shape and optionally suitable (possibly different) coatings of the front and / or back.
  • suitable (possibly different) coatings of the front and / or back can be used.
  • glass reflectors with reflective and in particular selectively reflective or dichroic coating can be used.
  • the or each support element is formed as extruded or extruded profile, and in particular consists of aluminum or an aluminum alloy.
  • the or each reflector surface is held by a latching or snap connection in the respective support element.
  • a preferred embodiment of both above-mentioned concept of the invention provides that the controllable reflector is subdivided in the longitudinal direction, wherein at least a first and second part are movable independently of each other such that in operation of the device selectively only one of them in the first, but the other is in the second position.
  • This allows in a very simple and efficient way, a so-called "format shutdown" in printing presses in which substrates of different widths are printed.
  • Such an adaptation has the advantage that radiation is introduced into the processing installation (eg printing press) only to the extent actually required by the irradiation device and unnecessary heating of machine sections not covered by a workpiece is avoided.
  • this embodiment is designed such that between the first and second part of the controllable reflector, a movement direction-dependent driver is provided, which carries the second part only in one direction of movement with the first part, but does not take along in another direction of movement.
  • the first and second part are rotatable on a common axis and the driver acts rotationally dependent.
  • this training is designed so that the first and second part mounted on a common hollow shaft and are separately driven via this or a separate power transmission element received therein.
  • the or each radiation source is assigned at least one auxiliary reflector which can be folded or displaced into a maintenance position.
  • This can in particular at the same time form a housing part - this is not absolutely necessary in the sense of this variant.
  • the respective radiation source accessible and can be easily replaced or possibly even cleaned.
  • a first preferred embodiment provides that the auxiliary reflector is designed and mounted so that by folding or moving it the radiation source is sufficiently accessible in the exchange of the same.
  • the or each radiation source associated with each two at the same time a housing part, hinged or sliding auxiliary reflectors and these are designed and stored in such a way that by folding down the same source of radiation is available for replacing the same extent sufficient.
  • each folding or sliding auxiliary reflector is held by a latching or snap connection to a stationary housing part in the operating position.
  • Another relatively independent embodiment of the invention provides that an actively cooled radiation absorber is arranged in that emission direction of the controllable reflector, in which the processing radiation is deflected away from the substrate.
  • the radiation absorber in particular has a cooling fluid channel whose surface facing the controllable reflector has a high absorption capacity for the radiation of the radiation source (s).
  • the cooling fluid channel of the radiation absorber is designed and dimensioned as a cooling air channel.
  • the cooling fluid channel (with a correspondingly stable wall) is designed such that it forms the mechanical support of the entire irradiation device. Then, in particular at least a part of the auxiliary reflectors is hinged or slidably mounted thereto, and also the support and contacting of the radiation sources is then mounted in the region of the cooling fluid channel.

  • the or each radiation source is a medium or high pressure UV emitter.
  • the wavelength-selective controllable reflector and / or auxiliary reflector has a high reflection coefficient in the UV range and a significantly lower reflection coefficient in the IR range.
  • other types of wavelength selectivity are also potentially important for specific applications, but under the aspect discussed above of minimizing heat radiation in many applications of UV drying / crosslinking processes, this UV / IR selectivity is of particular importance.
  • it can be realized by coating the reflector surface (s) with a dichroic layer.
  • the or each radiation source is forcibly cooled by blown into the housing and / or extracted from the housing cooling air.
