Description

Behandlungsmaschine für Behälter  Treatment machine for containers
Die Erfindung betrifft eine Behandlungsmaschine für Behälter und insbesondere eine Direktdruckmaschine. The invention relates to a treatment machine for containers and in particular a direct printing machine.
Für die Behandlung von Behältern in Abfüllanlagen werden zunehmend UV-reaktive Materialien, wie beispielsweise UV-reaktive Druckfarben, Kleber, Beschichtungen oder dergleichen verwendet. Die Produktionsbereiche mit den zugehörigen Behandlungsaggregaten und Transportmitteln für die Behälter werden in der Regel aus Gründen des Arbeitsschutzes, zur Klimatisierung und/oder zur Abschottung störender Umgebungsbeleuchtung mit Einhausun- gen umgeben. For the treatment of containers in bottling plants increasingly UV-reactive materials, such as UV-reactive inks, adhesives, coatings or the like are used. The production areas with the associated treatment units and means of transport for the containers are generally surrounded by enclosures for reasons of occupational safety, for air-conditioning and / or for sealing off disturbing ambient lighting.
Eine Abdunkelung der Produktionsbereiche dient dann sowohl dazu, die UV-reaktiven Materialien kontrollierter zu verarbeiten, als auch Fehlfunktionen der Behandlungsaggregate aufgrund von ausgehärteten Resten der UV-reaktiven Materialien zu vermeiden, und Personal außerhalb des Produktionsbereich vor schädlicher UV-Strahlung zu schützen. Dimming of the production areas then serves both to process the UV-reactive materials in a more controlled manner, to avoid malfunction of the treatment units due to cured residues of the UV-reactive materials, and to protect personnel outside the production area from harmful UV radiation.
Andererseits kann eine visuelle Kontrolle des laufenden Produktionsbetriebs und/oder eine Justierung der mit den UV-reaktiven Materialien versorgten Behandlungsaggregate erforderlich werden, wofür der abgedunkelte Produktionsbereich zumindest zeitweise geeignet beikeuchtet werden muss. On the other hand, a visual control of the current production operation and / or an adjustment of the treatment units supplied with the UV-reactive materials may be required, for which purpose the darkened production area must be suitably at least temporarily grouted.
In der Regel fallen im Produktionsbereich zusätzlich Wartungsarbeiten und/oder Montagearbeiten an den Behandlungsaggregaten und/oder Transportmitteln an. Hierfür wird eine vergleichsweise helle und farbneutrale Beleuchtung sämtlicher betroffener Maschinenbereiche benötigt. Zu diesem Zweck hat sich insbesondere Kaltlicht aus im Maschineninnenraum dauerhaft montierten Leuchtstoffröhren bewährt. As a rule, additional maintenance and / or assembly work on the treatment units and / or means of transport are incurred in the production area. For this purpose, a comparatively bright and color-neutral illumination of all affected machine areas is required. For this purpose, in particular cold light from permanently mounted in the machine interior fluorescent tubes has proven.
Aufgrund ihrer Helligkeit und dem hohen UV-Emissionsanteil führt eine derartige Beleuchtung jedoch zu unerwünschter Aushärtung von Resten UV-reaktiver Materialien, wie beispielsweise UV-reaktiver Druckfarben (Tinten) an Druckköpfen. Dies kann im nachfolgenden Produktionsbetrieb sowohl die Produktqualität verschlechtern als Fehlfunktionen und/oder Ausfälle einzelner Behandlungsaggregate, Druckköpfe oder dergleichen nach sich ziehen. However, due to their brightness and the high level of UV emission, such illumination leads to unwanted curing of residues of UV-reactive materials, such as UV-reactive inks (inks) on printheads. In the subsequent production operation, this can both degrade the product quality as result in malfunctions and / or failures of individual treatment units, printheads or the like.
Es besteht daher der Bedarf für eine diesbezügliche verbesserte Beleuchtung von Maschi- neninnenräumen bzw. Produktionsbereichen von Behandlungsmaschinen für Behälter, in denen UV-reaktive Materialien verarbeitet werden. Die gestellte Aufgabe wird mit einer Behandlungsmaschine für Behälter gemäß Anspruch 1 gelöst. Die Behandlungsmaschine ist vorzugsweise eine Direktdruckmaschine. Die Behandlungsmaschine umfasst einen Produktionsbereich mit einem Transportmittel für die Behälter und mit Behandlungsaggregaten zum Anbringen und/oder Härten UV-reaktiver Materialien an den Behältern, eine den Produktionsbereich umgebende Einhausung und eine Beleuchtung für den Produktionsbereich. Die Beleuchtung ist zwischen einem Produktionsmodus und einem Wartungsmodus gesteuert veränderbar, sodass ein UV-Emissionsanteil des im Produktionsmodus emittierten Lichts dann gegenüber dem Wartungsmodus reduziert ist. There is therefore a need for an improved illumination of machine interiors or production areas of treatment machines for containers in which UV-reactive materials are processed. The object is achieved with a treatment machine for containers according to claim 1. The treatment machine is preferably a direct printing machine. The treatment machine comprises a production area with a transport means for the containers and with treatment units for attaching and / or curing UV-reactive materials to the containers, a housing surrounding the production area and a lighting for the production area. The lighting is changeable controlled between a production mode and a maintenance mode, so that a UV emission component of the light emitted in the production mode is then reduced compared to the maintenance mode.
Dadurch lässt sich verhindern, dass Reste der UV-reaktiven Materialien im Bereich der Behandlungsaggregate bei Kontrollen während des Produktionsbetriebs und/oder bei zwischenzeitlichen Justagearbeiten aushärten und die Funktion der betroffenen Behandlungsaggregate auf unerwünschte Weise beeinträchtigen. As a result, it is possible to prevent residues of the UV-reactive materials in the area of the treatment units from hardening during checks during production operation and / or during interim adjustment work and to impair the function of the treatment units concerned in an undesired manner.
Demgegenüber ist für Wartungsarbeiten bzw. Montagearbeiten in der Regel eine Beleuchtung durch Kaltlicht mit vergleichsweise viel Strahlleistung und UV-Anteil notwendig. In contrast, for maintenance or assembly work usually lighting by cold light with comparatively much beam power and UV content is necessary.
Der Produktionsbereich ist ein Maschineninnenraum der Behandlungsmaschine, der von der Einhausung aus Gründen des Arbeitsschutzes, der Maschinenklimatisierung und/oder der Abdunkelung des Produktionsbereichs umgeben ist. The production area is a machine interior of the treatment machine, which is surrounded by the housing for reasons of occupational safety, machine air conditioning and / or darkening of the production area.
Die veränderbare Beleuchtung ist im Inneren der Einhausung angebracht, im Gegensatz zur Umgebungsbeleuchtung der Produktionshalle oder dergleichen. The variable lighting is mounted inside the enclosure, in contrast to the ambient lighting of the production hall or the like.
Das Ausschalten der Beleuchtung ist keine erfindungsgemäße Reduzierung der Gesamtstrahlleistung. Gemeint ist eine Reduzierung bei visuell wahrnehmbarer Lichtemission. Turning off the lighting is not a reduction of the total beam power according to the invention. This refers to a reduction in visually perceptible light emission.
Vorzugsweise sind für den Produktionsmodus und den Wartungsmodus separat einschaltbare Lampen vorhanden, die unterschiedliche Emissionsspektren aufweisen. Die Lampen für den Produktionsmodus weisen dann beispielsweise einen gegenüber den Lampen für den Wartungsmodus reduzierten Emissionsanteil im UVA-, UVB- und/oder UVC-Spektralbereich auf. Die separaten Lampen können zeitweise oder dauerhaft im jeweils zugeordneten Modus eingeschaltet werden. Preferably, separately switchable lamps are present for the production mode and the maintenance mode, which have different emission spectra. The lamps for the production mode then have, for example, a reduced emission in the UVA, UVB and / or UVC spectral range compared to the lamps for the maintenance mode. The separate lamps can be switched on temporarily or permanently in the respectively assigned mode.
Vorzugsweise umfasst die Beleuchtung Lampen mit für den Produktionsmodus selektiv vor- schaltbaren UV-Emissionsschutzfiltern. Dadurch lässt sich die Strahlleistung der Beleuchtung beispielsweise UVA-, UVB- und/oder UVC-Spektralbereich gezielt reduzieren. Separate Lampen für den Produktionsmodus sind dann entbehrlich. Vorzugsweise umfasst die Beleuchtung Lampen mit gezielt veränderbarem Emissionsspektrum. Die Lampen könnten beispielsweise Mehrfarben-LED umfassen, die auf an sich bekannte Weise spektral durchstimmbar sind, sodass für den Produktionsbetrieb und den Wartungsbetrieb unterschiedliche Farbtemperaturen und/oder Spektralbereiche der Emission eingestellt werden können. The illumination preferably comprises lamps with UV emission protection filters which can be selectively switched on for the production mode. As a result, the beam power of the illumination, for example UVA, UVB and / or UVC spectral range, can be purposefully reduced. Separate lamps for the production mode are then unnecessary. The illumination preferably comprises lamps with a specifically variable emission spectrum. The lamps could, for example, comprise multi-color LEDs which can be spectrally tuned in a manner known per se, so that different color temperatures and / or spectral ranges of the emission can be set for the production mode and the maintenance mode.
Vorzugsweise umfasst die Beleuchtung Lampen sowie wenigstens einen zugeordneten Dimmer zum selektiven Dimmen der Lampen im Produktionsbetrieb. Das Dimmen der Lampen ist sowohl für sich allein als auch in Kombination mit einer Änderung des Emissionsspektrums der Lampen möglich. Beispielsweise wird im Produktionsbetrieb lediglich eine prinzipielle visuelle Kontrolle bestimmter Maschinenfunktionen und/oder Bewegungsabläufe benötigt. Hierfür kann eine gegenüber dem Wartungsmodus reduzierte Gesamtstrahlleistung der Beleuchtung durch Dimmen vorteilhaft und/oder bereits ausreichend sein. Preferably, the lighting comprises lamps and at least one associated dimmer for selective dimming of the lamps in production operation. The dimming of the lamps is possible both on its own and in combination with a change in the emission spectrum of the lamps. For example, only a basic visual control of certain machine functions and / or movement sequences is required in production operation. For this purpose, compared to the maintenance mode reduced overall beam power of lighting by dimming can be advantageous and / or already sufficient.
Vorzugsweise weist die Einhausung eine Gesamtlichtdurchlässigkeit von/nach außen von höchstens 20 % auf. Die Einhausung ist somit zur Abdunkelung des Produktionsbereichs bzw. Maschineninnenraums ausgebildet. Die Abdunkelung verhindert, dass außerhalb der Einhausung vorhandene Lichtquellen UV-reaktive Materialien im Produktionsbereich auf unerwünschte Weise härten und/oder für Personen gefährliche UV-Strahlung nach außen dringt. Bei derart abgedunkeltem Produktionsbereich ist die erfindungsgemäße Beleuchtung für eine Produktionskontrolle und/oder Wartungsarbeiten besonders vorteilhaft. Preferably, the enclosure has a total light transmission to / from the outside of at most 20%. The housing is thus designed to darken the production area or machine interior. The darkening prevents light sources outside the enclosure from undesirably curing UV-reactive materials in the production area and / or from UV radiation that is hazardous to people. With such a darkened production area, the illumination according to the invention is particularly advantageous for production control and / or maintenance work.
Vorzugsweise weist die Beleuchtung im Wartungsmodus eine Farbtemperatur von höchstens 5000 K, und insbesondere von höchstens 3300 K, auf. Bei einer Farbtemperatur von höchstens 3300 K spricht man auch von Tageslichtweiß oder Kaltweiß, bei einer Farbtemperatur von 3300 bis 5000 K von Neutralweiß. Derartiges Licht eignet sich besonders für Montagearbeiten und die visuelle Inspektion von Maschinenkomponenten. In the maintenance mode, the illumination preferably has a color temperature of at most 5000 K, and in particular of at most 3300 K. With a color temperature of at most 3300 K one speaks also of daylight white or cold white, with a color temperature of 3300 to 5000 K of neutral white. Such light is particularly suitable for assembly work and visual inspection of machine components.
Vorzugsweise ist die Strahlleistung des im Produktionsmodus emittierten Lichts für einen Spektralbereich von 200 bis 450 nm um wenigstens 90 % gegenüber dem Wartungsmodus reduziert. Damit lässt sich ein UV-Spektralbereich, der für die Härtung UV-reaktiver Materialien besonders wichtig ist, gezielt für die Produktion abschwächen / ausblenden, um unerwünschte Härtung der UV-reaktiven Materialien zu vermeiden. Preferably, the beam power of the light emitted in the production mode for a spectral range of 200 to 450 nm is reduced by at least 90% compared to the maintenance mode. In this way, a UV spectral range, which is particularly important for the curing of UV-reactive materials, can be selectively weakened / masked out for production in order to avoid unwanted curing of the UV-reactive materials.
Die erfindungsgemäße Reduzierung des UV-Emissionsanteils kann mit einer Reduzierung der Gesamtstrahlleistung einhergehen. Vorzugsweise wird die Gesamtstrahlleistung beim Übergang vom Wartungsmodus in den Produktionsmodus um höchstens 75%, insbesondere höchstens 50%, reduziert. Dies ermöglicht eine in vielen Fällen ausreichende Helligkeit im Produktionsbereich für eine visuelle Inspektion im Produktionsbetrieb oder bei Produktionsunterbrechungen. The reduction of the UV emission component according to the invention can be accompanied by a reduction of the total jet power. Preferably, the total beam power at the transition from the maintenance mode to the production mode by at most 75%, in particular not more than 50%, reduced. This allows in many cases sufficient brightness in the production area for a visual inspection in production or in production stoppages.
Vorzugsweise ist die Beleuchtung sowohl im Produktionsmodus als auch im Wartungsmodus kontinuierlich. Darunter ist eine physiologisch als kontinuierlich empfundene Beleuchtung zu verstehen, im Gegensatz zur Wahrnehmung als Blinklicht, Blitzlicht oder dergleichen. Preferably, the lighting is continuous both in the production mode and in the maintenance mode. This is to be understood as a physiologically perceived as continuous lighting, in contrast to perception as a flashing light, flash or the like.
Vorzugsweise sind/umfassen die Behandlungsaggregate Druckaggregate zum Verarbeiten UV-härtender Tinten. Derartige Druckaggregate umfassen Druckköpfe zum Ausstoßen der UV-härtenden Tinten, die besonders empfindlich bezüglich eines unerwünschten Härtens der Tinten bei Produktionsunterbrechungen, Wartungsarbeiten oder dergleichen sind. Ein Beleuchtungswechsel zwischen Produktionsmodus und Wartungsmodus ist für einen ordnungsgemäßen und fehlerfreien Betrieb von Druckaggregaten somit besonders vorteilhaft. Preferably, the treatment units are printing units for processing UV-curable inks. Such printing units include printheads for ejecting the UV-curable inks, which are particularly sensitive to undesirable curing of the inks during production stoppages, maintenance or the like. An illumination change between production mode and maintenance mode is thus particularly advantageous for the proper and error-free operation of printing units.
Vorzugsweise ist der Produktionsbereich klimatisiert. Eine derartige Klimatisierung erfordert eine geschlossene Einhausung, sodass sich die Beleuchtungsverhältnisse im Produktionsbereich / Maschineninnenraum erheblich von den Beleuchtungsverhältnissen außerhalb der Einhausung unterscheiden. Entsprechend ist ein Beleuchtungswechsel zwischen Produktionsmodus und Wartungsmodus unter diesen Umständen besonders vorteilhaft. Preferably, the production area is conditioned. Such air conditioning requires a closed enclosure, so that the lighting conditions in the production area / machine interior significantly differ from the lighting conditions outside the enclosure. Accordingly, a lighting change between production mode and maintenance mode under these circumstances is particularly advantageous.
Vorzugsweise umfasst die Behandlungsmaschine ferner eine Steuereinheit zum bedienerin- duzierten und/oder maschineninduzierten Beleuchtungswechsel zwischen dem Produktionsmodus und dem Wartungsmodus. Beispielsweise kann die Steuereinheit einen Touch- screen oder dergleichen Eingabeeinheit umfassen, mit der Bediener gezielt zwischen dem Produktionsmodus und dem Wartungsmodus wechseln können. Der Wechsel kann auch automatisch ausgelöst werden, insbesondere abhängig von definierten Maschinenzustän- den, wie beispielsweise laufendem oder stehendem Transportmittel. Preferably, the treatment machine further comprises a control unit for the operator-induced and / or machine-induced lighting change between the production mode and the maintenance mode. For example, the control unit may include a touch screen or the like input unit, with the operator can selectively switch between the production mode and the maintenance mode. The change can also be triggered automatically, in particular depending on defined machine states, such as running or stationary means of transport.
Vorzugsweise ist das Transportmittel ein kontinuierlich drehbares Karussell, und die Behandlungsaggregate sind in der Peripherie des Karussells insbesondere stationär angeordnet und von der Einhausung umgeben. Anders gesagt definiert die Einhausung dann einen Maschineninnenraum, in dem wenigstens das Karussell und die Behandlungsaggregate im Produktionsbetrieb angeordnet sind. Für die Wartung der Aggregate kann die Einhausung gegebenenfalls geöffnet werden, um einen verbesserten Zugang zu den betroffenen Behandlungsaggregaten zu ermöglichen. Eine bevorzugte Ausführungsform der Erfindung ist zeichnerisch dargestellt. Es zeigen: Preferably, the transport means is a continuously rotatable carousel, and the treatment units are arranged in particular stationary in the periphery of the carousel and surrounded by the housing. In other words, the housing then defines a machine interior in which at least the carousel and the treatment units are arranged in the production operation. For the maintenance of the aggregates, the enclosure may be opened, if necessary, to allow improved access to the treatment units concerned. A preferred embodiment of the invention is shown in the drawing. Show it:

Fig. 2 Varianten der Beleuchtung zum Wechsel zwischen Produktionsmodus und Wartungsmodus. Fig. 2 variants of lighting for switching between production mode and maintenance mode.
Wie die Fig. 1 im Schnitt von oben erkennen lässt, umfasst die Behandlungsmaschine 1 für Behälter 2, die insbesondere Direktdruckmaschine ist, einen Produktionsbereich 3 mit einem Transportmittel 4 für die Behälter 2 und mit Behandlungsaggregaten 5 zum Anbringen und/oder Härten UV-reaktiver Materialien 6, die insbesondere UV-reaktive Druckfarben sind, an den Behältern 2. Der Produktionsbereich 3 ist von einer Einhausung 7 umgeben und definiert somit einen Maschineninnenraum, der wenigstens das Transportmittel 4 und die Behandlungsaggregate 5 aufnimmt. Schematisch angedeutet sind weitere, an sich bekannte Maschinenkomponenten, wie beispielsweise ein Einlaufstern, ein Auslaufstern sowie Pin- ning-Einheiten und Inspektionseinheiten. As can be seen in Fig. 1 in section from above, comprises the processing machine 1 for container 2, which is in particular direct printing machine, a production area 3 with a transport means 4 for the container 2 and with treatment units 5 for mounting and / or curing of UV-reactive materials 6, which are in particular UV-reactive printing inks, on the containers 2. The production area 3 is surrounded by an enclosure 7 and thus defines a machine interior, which accommodates at least the transport means 4 and the treatment units 5. Schematically indicated are further machine components known per se, such as, for example, an infeed star, an outlet star and pinching units and inspection units.
Innerhalb der Einhausung ist eine Beleuchtung 8 für den Produktionsbereich 3 bzw. den Maschineninnenraum der Behandlungsmaschine 1 vorhanden. Die Beleuchtung 8 ist beispielsweise an Säulen 7a der Einhausung 7 und/oder oberhalb der Transportmittels 4 und/oder der Behandlungsaggregate 5 befestigt. Within the enclosure lighting 8 for the production area 3 and the machine interior of the treatment machine 1 is present. The lighting 8 is attached, for example, to columns 7a of the housing 7 and / or above the transport means 4 and / or the treatment units 5.
Die Beleuchtung 8 kann mittels einer Steuerung 9 automatisch oder manuell an einer Bedieneinheit 9a, wie beispielsweise einem Touchscreen, zwischen wenigstens einem Wartungsmodus 10 und wenigstens einem Produktionsmodus 1 1 gezielt verändert werden. The lighting 8 can be changed by means of a control 9 automatically or manually on a control unit 9a, such as a touch screen, between at least one maintenance mode 10 and at least one production mode 1 1 targeted.
Zu diesem Zweck umfasst die Beleuchtung 8 Lampen 12, 13, die mit unterschiedlicher Spektralverteilung emittieren. Beispielsweise werden im Wartungsmodus 10 nur die Lampen 12 eingeschaltet und im Produktionsmodus 1 1 nur die Lampen 13 mit demgegenüber geringerem UV-Emissionsanteil. For this purpose, the illumination 8 comprises lamps 12, 13 which emit with different spectral distribution. For example, in the maintenance mode 10, only the lamps 12 are switched on and in the production mode 1 1, only the lamps 13 with the opposite, lower UV emission content.
Dies ist in der Fig. 1 nur zur Veranschaulichung gleichzeitig dargestellt, wobei gestrichelte Füllungen der Symbole ausgeschaltete Lampen bezeichnen. Denkbar ist auch, dass die Lampen 12, 13 im Wartungsmodus 10 gemeinsam eingeschaltet werden können und in Addition ein für Wartungsarbeiten geeignetes Weißlicht emittieren, und dass im Produktionsmodus 1 1 nur die Lampen 13 betrieben werden. Beispielhaft ist ferner eine Beleuchtungsvariante angedeutet, bei der die Lampen 12 sowohl im Wartungsmodus 10 als auch im Produktionsmodus 1 1 eingeschaltet werden können. Es wird dann ein UV-Emissionsschutzfilter 14 selektiv im Produktionsmodus 1 1 vor der Lampe 12 angeordnet. Der UV-Emissionsschutzfilter 14 reduziert die Abstrahlung eines für die Härtung der UV-reaktiven Materialien 6 kritischen UV-Spektralanteils der Lampen 12. This is illustrated in FIG. 1 for illustrative purposes only, with dashed fillings of the symbols denoting deactivated lamps. It is also conceivable that the lamps 12, 13 in the maintenance mode 10 can be switched on together and emit in addition a suitable for maintenance white light, and that in the production mode 1 1 only the lamps 13 are operated. By way of example, a lighting variant is also indicated, in which the lamps 12 can be switched on both in the maintenance mode 10 and in the production mode 11. It is then a UV emission protection filter 14 selectively placed in production mode 1 1 in front of the lamp 12. The UV emission protection filter 14 reduces the radiation of a critical for the UV-reactive materials 6 UV spectral component of the lamps 12th
Ergänzend oder alternativ ist es auch möglich, die Lampe 12 für den Produktionsmodus 1 1 gezielt zu dimmen, um die Strahlleistung im relevanten UV-Spektralanteil allein auf diese Weise oder in Kombination mit dem UV-Emissionsschutzfilter 14 gezielt gegenüber dem Wartungsmodus 10 zu reduzieren. Auch die separat im Produktionsmodus einschaltbaren Lampen 13 können gedimmt werden. Additionally or alternatively, it is also possible to specifically dim the lamp 12 for the production mode 1 1 in order to reduce the beam power in the relevant UV spectral component alone in this way or in combination with the UV emission protection filter 14 in a targeted manner compared to the maintenance mode 10. The separately switchable in production mode lamps 13 can be dimmed.
Ergänzend oder alternativ kann die Beleuchtung 8 Lampen 15 mit durchstimmbaren Mehrfarben-LED umfassen, deren Emissionsspektrum / Farbtemperatur mit feiner Abstufung gesteuert verändert werden können und/oder auch deren Helligkeit. In addition or as an alternative, the illumination 8 can comprise multicolor tunable multi-color lamps 15 whose emission spectrum / color temperature can be changed in a controlled manner with a fine gradation and / or their brightness.
Eine gezielte Veränderung der Beleuchtung 8 ist bei den LED-Lampen 15 beispielsweise durch Auswahl von Beleuchtungsprogrammen an der Steuerung 9 möglich. Zu diesem Zweck können auch jeweils mehrere Beleuchtungsprogramme für den Wartungsmodus 10 bzw. Produktionsmodus 1 1 abgespeichert sein. A targeted change in the lighting 8 is possible in the LED lamps 15, for example by selecting lighting programs on the controller 9. For this purpose, a plurality of illumination programs for the maintenance mode 10 or production mode 1 1 can also be stored in each case.
Die Fig. 2 verdeutlicht schematisch eine Veränderung des von der Beleuchtung 8 emittierten Lichts 8a, wobei beispielhaft ein UV-Emissionsanteil 16 und eine Gesamtstrahlleistung 17 des von der Beleuchtung 8 emittierten Lichts 8a für den Wartungsmodus 10 mit durchgezogenen Linien und für den Produktionsmodus 1 1 gestrichelt dargestellt ist. FIG. 2 schematically illustrates a change in the light 8a emitted by the illumination 8, wherein, by way of example, a UV emission component 16 and a total radiation output 17 of the light 8a emitted by the illumination 8 for the maintenance mode 10 are dashed with solid lines and for the production mode 11 is shown.
Vorzugsweise wird die Strahlleistung der Beleuchtung 8 im Produktionsmodus 1 1 für einen Spektralbereich 18 der Wellenlänge λ von 200 bis 450 nm vorzugsweise um wenigstens 90 % gegenüber dem Wartungsmodus 10 reduziert. Damit lässt sich eine unerwünschte Härtung UV-reaktiver Materialien, insbesondere UV-reaktiver Druckfarben (Tinten), besonders effizient vermeiden, insbesondere ohne störende Beeinträchtigung des sichtbaren Spektralanteils. Preferably, the beam power of the illumination 8 in the production mode 1 1 for a spectral range 18 of the wavelength λ of 200 to 450 nm is preferably reduced by at least 90% compared to the maintenance mode 10. This makes it possible to avoid an undesirable hardening of UV-reactive materials, in particular UV-reactive printing inks (inks), particularly efficiently, in particular without disturbing impairment of the visible spectral component.
Dies hat gegebenenfalls eine Reduzierung der Gesamtstrahlleistung 17 der Beleuchtung 8 im Produktionsmodus 1 1 gegenüber dem Wartungsmodus 10 zur Folge. Für Justagearbeiten und/oder Produktionskontrollen ist eine kontrollierte Reduzierung der Gesamtstrahlleistung 17 in der Regel unproblematisch. Die Einhausung 7 ist vorzugsweise zur Abdunkelung des Produktionsbereichs 3 bzw. des Maschineninnenraums der Behandlungsmaschine 1 ausgebildet, insbesondere mit einer Gesamtlichtdurchlässigkeit von höchstens 20 %. Die Einhausung 7 kann zu diesem Zweck lichtundurchlässige Wandbereiche und getönte Scheiben oder dergleichen umfassen. This may result in a reduction of the total beam power 17 of the illumination 8 in the production mode 1 1 compared to the maintenance mode 10. For adjustment work and / or production controls a controlled reduction of the total jet power 17 is usually unproblematic. The housing 7 is preferably designed to darken the production area 3 or the machine interior of the treatment machine 1, in particular with a total light transmittance of at most 20%. The enclosure 7 may for this purpose comprise opaque wall areas and tinted windows or the like.
Die Lampen 12, 15 haben im Wartungsmodus 10 vorzugsweise eine Farbtemperatur von höchstens 5000 K und emittieren somit entweder Neutralweiß oder Tageslichtweiß bzw. Kaltweiß. Als besonders farbneutral wird eine Emission der Lampen 12, 15 von Tageslichtweiß / Kaltweiß bei Farbtemperaturen von höchstens 3300 K empfunden. Dies erleichtert die visuelle Inspektion und Montage von Maschinenkomponenten der Behandlungsmaschine 1. The lamps 12, 15 in the maintenance mode 10 preferably have a color temperature of at most 5000 K and thus emit either neutral white or daylight white or cold white. An emission of the lamps 12, 15 from daylight white / cold white at color temperatures of at most 3300 K is perceived as being particularly neutral in color. This facilitates the visual inspection and assembly of machine components of the processing machine 1.
Für spektral durchstimmbare Lampen 15 eignen sich Dimmer 19 und Farbwähler 20, die beispielsweise in die Steuerung 9 integriert sein können. Mit diesen könnten Farbtemperatur, UV-Emissionsanteil 16 und/oder Gesamtstrahlleistung 17 für den Wartungsmodus 10 und den Produktionsmodus 1 1 beispielsweise innerhalb zulässiger Verstellbereiche sowohl automatisch als auch manuell angepasst werden. For spectrally tunable lamps 15 are dimmer 19 and color picker 20, which may be integrated, for example, in the controller 9. With these color temperature, UV emission ratio 16 and / or total beam power 17 for the maintenance mode 10 and the production mode 1 1 could be adjusted both automatically and manually, for example, within allowable adjustment ranges.
Die Beleuchtung 8 ist bei allen beispielhaft dargestellten Lampen 12, 13, 15 sowohl im Wartungsmodus 10 als auch im Produktionsmodus 1 1 visuell kontinuierlich, im Gegensatz zu einer blinkenden Beleuchtung oder dergleichen. The lighting 8 is visually continuous in all the lamps 12, 13, 15 shown by way of example, both in the maintenance mode 10 and in the production mode 1 1, in contrast to a flashing lighting or the like.
Nichtsdestoweniger könnte die Beleuchtung 8 wenigstens einen zusätzlichen Warnmodus aufweisen, in dem die Beleuchtung 8 beispielsweise auf Blinklicht und/oder Rotlicht oder dergleichen wechselt. Nevertheless, the lighting 8 could have at least one additional warning mode in which the lighting 8 changes, for example, to flashing light and / or red light or the like.
Der Wechsel zwischen dem Wartungsmodus 10 und dem Produktionsmodus 1 1 kann sowohl durch Bedienpersonal manuell an der Bedieneinheit 9a ausgelöst werden als auch automatisch, beispielsweise abhängig von bestimmten in der Steuerung 9 festgestellten Ma- schinenzuständen. Ein automatischer Wechsel in den Produktionsmodus 1 1 kann sinnvoll sein, um eine unerwünschte Härtung der UV-reaktiven Materialien, wie beispielsweise Druckfarben oder dergleichen Beschichtungen, an Maschinenkomponenten besonders zuverlässig zu vermeiden. The change between the maintenance mode 10 and the production mode 1 1 can be triggered both manually by operating personnel on the operating unit 9a and automatically, for example, depending on certain machine states determined in the control 9. An automatic change to the production mode 1 1 may be useful to avoid unwanted curing of UV-reactive materials, such as printing inks or the like coatings on machine components particularly reliable.
Das Transportmittel 4 ist vorzugsweise ein kontinuierlich drehbares Karussell mit an sich bekannten, beispielsweise mittels Servomotoren individuell drehbaren Halterungen 21 für die Behälter 2 (nur in einem Teilbereich des Karussells schematisch angedeutet). Die Behandlungsaggregate 5 sind stationär in der Peripherie des Karussells angeordnet, können zu Wartungszwecken oder für Umrüstarbeiten oder dergleichen gegebenenfalls in eine dafür günstigere Position nach außen gefahren werden und/oder ausgetauscht werden. Zu diesem Zweck kann die Einhausung 7 segmentiert sein und Türen 7b zur Erleichterung von Wartungsarbeiten umfassen. Dies ist in der Fig. 1 oben schematisch angedeutet. The transport means 4 is preferably a continuously rotatable carousel with known per se, for example by means of servomotors individually rotatable brackets 21 for the container 2 (only schematically indicated in a portion of the carousel). The treatment units 5 are arranged stationarily in the periphery of the carousel, can be driven for maintenance purposes or for retooling or the like optionally in a more favorable position to the outside and / or exchanged. For this purpose, the enclosure 7 may be segmented and include doors 7b for ease of maintenance. This is schematically indicated in FIG. 1 above.
