Die Erfindung betrifft eine Leuchteneinrichtung an Hochgeschwindigkeits-Produktionsmaschine zum Herstellen von Produkten der Tabak verarbeitenden Industrie, wobei ein System von Leuchten vorgesehen ist, die im Bereich von Maschinenorganen ortsfest an der Maschine angeordnet sind, um jeweils entsprechend einem Maschinensteuertakt betriebene Maschinenorgane und/oder passierende Produkte zu beobachten.The invention relates to a lighting device on high-speed production machine for manufacturing products of the tobacco processing industry, wherein a system of lights is provided, which are arranged in the range of machine organs fixed to the machine, each operated according to a machine control cycle machine organs and / or passing products to observe.
Eine bekannte Einrichtung zum Überwachen der Einstellung einzelner Maschinenorgane an Produktionsmaschinen zum Herstellen von Artikeln der Tabak verarbeitenden Industrie weist Stroboskoplampen auf, die an ausgewählten Stellen der Produktionsmaschine fest installiert sind (
Der Erfindung liegt das Hauptziel zugrunde, eine multifunktionelle Leuchteneinrichtung an genannten Produktionsmaschinen der Tabak verarbeitenden Industrie zu schaffen. Insbesondere sollen ein besonders hoher Integrationsgrad von Gerätefunktionen sowie eine maschinengerechte und angepaßte Bauform erreicht werden, um Licht ein und derselben Lichtquelle wahlweise als Dauerlicht oder Stroboskoplicht zur Beobachtung, Wartung, Fehlersuche, Störungsanalyse und/oder Maschineneinstellung zu nutzen. Dabei soll die Qualität des Lichts für alle Funktionsbereiche auch bei unterschiedlichsten Anforderungen gleichermaßen gut sein. Eine integrierte Leuchtenkonstruktion soll einfach und kostengünstig sein. Ziel ist es auch, eine Einrichtung mit langer Standzeit und hoher Funktionszuverlässigkeit zu erhalten. Leuchten der multifunktionellen Leuchteneinrichtung sollen jeweils in engstem Raum montierbar sowie einfach und wirksam auf die zu beleuchtende Stelle ausrichtbar sein.The invention has the main object of providing a multifunctional lighting device on said production machines of the tobacco-processing industry. In particular, a particularly high degree of integration of device functions and a machine-compatible and adapted design should be achieved in order to use light from the same light source optionally as a continuous light or strobe light for observation, maintenance, troubleshooting, fault analysis and / or machine setting. At the same time, the quality of the light should be equally good for all functional areas, even with a wide variety of requirements. An integrated luminaire construction should be simple and inexpensive. The aim is also to obtain a device with a long service life and high functional reliability. Lights of the multifunctional lighting device should be mounted in a confined space and also easily and effectively aligned to the spot to be illuminated.
Die Ziele der Erfindung werden in Verbindung mit den Merkmalen der eingangs genannten Leuchteneinrichtung dadurch erzielt, daß jede Leuchte durch wenigstens eine sichtbares Licht emittierende Leistungs-Halbleiterlichtquelle, insbesondere eine Leuchtdiode, oder durch wenigstens ein entsprechendes pulssteuerbares Leuchtelement gebildet ist und die Einrichtung eine mit den Leuchten elektrisch verbundene elektronische Betriebs-Steuereinheit zum wahlweise einstellbaren Betrieb der Leuchten umfaßt, wobei einerseits Betrieb mit gleichmäßigem Dauerlicht zum Ausleuchten von Maschinenorganen und/oder Produkten sowie andererseits Betrieb mit entsprechend dem Maschinensteuertakt periodisch unterbrochenem Stroboskoplicht zum Erzeugen von scheinbaren Bildern, die Bewegungsabläufe von Maschinenorganen und/oder Produkten darstellen, einstellbar ist. Erfindungsgemäß wird erreicht, daß das System von Leuchten, deren Halbleiterlichtquellen mittels Pulsfolgen steuerbar sind, multifunktionell nutzbar ist. Es ist von besonderem Vorteil, daß mit ein und demselben Mittel einerseits eine langlebige Dauerbeleuchtung mit leistungsstarkem homogenem Licht zum Ausleuchten von Maschinenorganen über weite Leuchtbereiche zur Verfügung steht und daß andererseits in der Stroboskop-Betriebsart bisher nicht gekannte Präzision sowie Flexibilität zur Fehlersuche, Kontrolle, Nach- und Einstellung erzielt werden. Von wesentlicher Bedeutung ist auch, daß jede Leuchte in engstem Raum montierbar ist. Aufgrund von Leistungsbetrieb in allen Betriebsarten werden maximale Lichtstärken mit optimalen Ausleuchtbereichen erzielt. Mit dem System der Mehrzahl von Leuchten in der Produktionsmaschine lassen sich Meßergebnisse an unterschiedlichen Stellen in der Maschine vergleichen. Es wird die Hochgeschwindigkeitstechnik der Spezialmaschinen der Tabakindustrie beherrschbar. Man erreicht besonders schnelle Fehlereingrenzung in Verbindung mit erhöhter Maschinenverfügbarkeit. Typische Produktfehler wie zum Beispiel Abdrücke an Zigaretten lassen sich schnell, einfach und zuverlässig in bezug auf eine verursachende Trommel in der Maschine lokalisieren. Auch im Hochgeschwindigkeitsbetrieb lassen sich Leimbildkontrollen und Korrekturen im Papierlauf vornehmen. Zum Beispiel läßt sich auch das Leimbild zum Schnitt an einer Rolltrommel präzise kontrollieren und einstellen. Falsche Produktlagen auf einer Trommel oder Bewegungen des Produktes auf der Trommel lassen sich schnell und zuverlässig feststellen. Mittels Stroboskopüberwachung wird die Stabilität des Flusses von Zigarettenfiltem gewährleistet. Im Stroboskopbetrieb lassen sich Baugruppen zum Beispiel zur Bänderrollung einfach einstellen. Allgemein ist die wirksame Kontrolle und Nachstellung von Maschinenorganen im Maschinenbetrieb hervorzuheben. Insbesondere läßt sich eine Online-Nachstellung der Übergabe von Produkten zwischen Trommeln schnell und zuverlässig durchführen. Zwischen Dauerlichtbetrieb und Stroboskoplichtbetrieb sind einfache und schnelle, maschinenangepaßte Umschaltung und Bedienung erreicht. Die in die Maschine integrierten Universalleuchten vermeiden für alle Betriebsarten Probe- oder Versuchsausrichtungen der Leuchtquellen. Reproduzierbarkeit behindernde Einzelmessungen entfallen. Eine mit dem Leuchtensystem ausgestattete Maschine läßt sich gefahrlos mit geschlossenen Schutzabdeckungen betreiben. Es steht ein System von kostengünstigen und langlebigen Halbleiterlichtquellen für die Maschinenbeleuchtung mit Dauerlicht sowie für das Erzeugen von scheinbaren Bildern mit Stroboskoplicht zur Verfügung. Im ganzen erhält man ein relativ einfaches, funktionsvielfältiges und funktionszuverlässiges Beleuchtungssystem, das kostengünstig und technisch einfach in eine Maschine zu integrieren ist und relativ lange Standzeit gewährleistet.The objects of the invention are achieved in conjunction with the features of the aforementioned lighting device in that each lamp is formed by at least one visible light emitting power semiconductor light source, in particular a light emitting diode, or by at least one corresponding pulse-controllable light emitting element and the device with the lights electrically connected electronic operating control unit for selectively adjustable operation of the lights comprises, on the one hand operation with uniform continuous light for illuminating machine organs and / or products and on the other hand operation according to the machine control clock periodically interrupted strobe light for producing apparent images, the movement of machine organs and / or products is adjustable. According to the invention it is achieved that the system of lights whose semiconductor light sources are controlled by means of pulse sequences, multi-functional usable. It is of particular advantage that with one and the same means on the one hand long-lasting continuous lighting with powerful homogeneous light for illuminating machine organs over wide luminous ranges available and that on the other hand in the stroboscope mode previously unknown precision and flexibility for troubleshooting, control, after - And adjustment can be achieved. It is also essential that each luminaire can be mounted in a confined space. Due to power operation in all modes maximum light levels are achieved with optimal illumination areas. With the system of the majority of lights in the production machine Measurement results can be compared at different points in the machine. It is the high-speed technology of the special machinery of the tobacco industry manageable. One achieves particularly fast fault isolation in connection with increased machine availability. Typical product defects such as imprints on cigarettes can be located quickly, easily and reliably with respect to a causative drum in the machine. Even in high-speed operation, gluing and corrections can be made in the paper path. For example, the glue pattern can also be precisely controlled and adjusted for cutting on a roller drum. Incorrect product layers on a drum or movements of the product on the drum can be detected quickly and reliably. By means of stroboscopic monitoring, the stability of the flow of cigarette filters is ensured. In stroboscopic mode, assemblies can be easily adjusted, for example, for belt rolling. In general, the effective control and adjustment of machine organs in machine operation should be emphasized. In particular, an online readjustment of the transfer of products between drums can be performed quickly and reliably. Between continuous light operation and stroboscopic light operation, simple and fast, machine-adapted switching and operation have been achieved. The universal luminaires integrated into the machine avoid sample or trial alignment of the luminaires for all operating modes. Reproducibility obstructing individual measurements omitted. A machine equipped with the lighting system can be operated safely with closed protective covers. A system of cost-effective and durable semiconductor light sources for machine lighting with continuous light and for generating apparent images with strobe light is available. On the whole, you get a relatively simple, function-rich and functionally reliable lighting system that is inexpensive and technically easy to integrate into a machine and ensures relatively long service life.
Um vorteilhaft ein automatisches Umschalten zwischen Stroboskopbetrieb bei laufender Maschine und Dauerbeleuchtung bei Maschinenstillstand zu erreichen, ist die Betriebs-Steuereinheit für eine Dauerlicht-Betriebsart zweckmäßig in einen Schaltzustand versetzbar, in dem wenigstens eine Leuchte frei von Ansteuerung durch die Betriebs-Steuereinheit bleibt, wobei die Leuchte direkt mit Versorgungsspannung, vorzugsweise Gleichspannung beaufschlagt wird. Zweckmäßig ist die Leuchte dann mit wenigstens einer elektronischen Dioden-Steuerschaltung ausgestattet, die selektiv in zwei Schaltzustände derart versetzbar ist, daß sie in Abhängigkeit von dem Vorhandensein bzw. Nicht-Vorhandensein eines Takt-Steuersignals der Betriebs-Steuereinheit zwischen getakteter und direkter ungetakteter Leuchtdioden-Spannungsversorgung umschaltet.In order to advantageously achieve automatic switching between stroboscopic operation while the machine is running and continuous lighting when the machine is at a standstill, the operating control unit for a continuous light operating mode is expediently displaceable into a switching state in which at least one luminaire remains free of activation by the operating control unit, wherein the Lamp directly with supply voltage, preferably DC voltage is applied. Appropriately, the light is then with at least an electronic diode control circuit which is selectively displaceable in two switching states so as to switch between clocked and direct uncaged light-emitting diode power supply in response to the presence or absence of a clock control signal of the operation control unit.
Eine besondere Ausgestaltung besteht darin, daß die Betriebssteuereinheit für eine Dauerlicht-Betriebsart in einen Schaltzustand versetzbar ist, in dem sie wenigstens eine Leuchte mit einem eine Pulsfolge aufweisenden Steuersignal beaufschlagt, dessen Pulsfrequenz zur Frequenz des Maschinentakts im Leuchtbereich der Leuchte asynchron ist. Zweckmäßig werden Pulsfrequenzen bei 450 bis 500 Hz eingestellt, um gegenüber einem Hochgeschwindigkeits-Produktionstakt in der Größenordnung von z.B. 200 bis 400 Hz ausgeprägte Asynchronität zu erzielen.A particular embodiment is that the operation control unit for a steady light mode is set into a switching state in which it acts on at least one lamp with a pulse train having a control signal whose pulse frequency is asynchronous to the frequency of the machine clock in the luminous area of the lamp. Conveniently, pulse frequencies are set at 450 to 500 Hz to provide a high-speed production clock on the order of e.g. 200 to 400 Hz to achieve pronounced asynchronism.
Eine bevorzugte Ausgestaltung der Betriebs-Steuereinheit der Leuchteneinrichtung besteht weiterhin darin, daß die Steuereinheit für eine Stroboskop-Betriebsart in einen Schaltzustand versetzbar ist, in dem sie wenigstens eine Leuchte mit einem eine Pulsfolge aufweisenden Steuersignal beaufschlagt, dessen Pulsfrequenz synchron mit dem Maschinen-Produktionstakt im Leuchtbereich der Leuchte gehalten wird. In dieser Einstellung wird an einem Maschinenorgan wie z.B. einer Trommel oder einer Mulde ein scheinbar stehendes Bild des geförderten Produkts bzw. Zwischenprodukts erzeugt. Zweckmäßig kann auch vorgesehen werden, daß die Betriebs-Steuereinheit für eine Stroboskop-Betriebsart in einen Schaltzustand versetzbar ist, in dem sie ein wenigstens eine Leuchte beaufschlagendes, eine Pulsfolge aufweisendes Steuersignal hervorbringt, das mit einem von Takt-Synchronität des Steuertakts mit dem Maschinentakt im Leuchtbereich der Leuchte abweichenden, einstellbaren Takt-Offset erzeugt wird. Diese geringfügig von Synchronität abweichende Frequenzverschiebung kann positiv oder negativ sein, um eine in der Produktionslinie in Richtung nach vom oder zurück scheinbar verlangsamte Bewegung des Maschinenorgans und/oder Produkts zu erzeugen.A preferred embodiment of the operating control unit of the lighting device further consists in that the control unit for a stroboscopic mode in a switching state is displaceable in which it acts on at least one lamp with a pulse train having a control signal whose pulse frequency synchronous with the machine production clock in Luminous area of the lamp is maintained. In this setting, on a machine organ such as e.g. a drum or a trough produces a seemingly stationary image of the conveyed product or intermediate product. Appropriately, it can also be provided that the operating control unit for a stroboscopic mode in a switching state is displaceable, in which it produces at least one luminaire beaufschlagendes, a pulse sequence exhibiting control signal, with a clock synchronism of the control clock with the machine cycle in Luminous range of the luminaire deviating, adjustable clock offset is generated. This slightly off-synchronous frequency shift may be positive or negative to produce movement of the machine organ and / or product that appears to be slowing in the production line in the direction of backwards or forwards.
Gemäß weiterer Ausgestaltung ist die Betriebs-Steuereinheit in einer Stroboskop-Betriebsart zweckmäßig in einen Schaltzustand versetzbar, in dem sie ein wenigstens eine Leuchte beaufschlagendes, eine Pulsfolge aufweisendes Steuersignal hervorbringt, das mit einstellbarer Phasenverschiebung zwischen dem Steuertakt und dem Maschinentakt im Leuchtbereich der Leuchte erzeugt wird. Mittels einer solchen Phasenverschiebung, die negativ oder positiv sein kann, wird ein stehend erscheinendes Objekt oder Produkt in seiner Bewegungsposition um ein der Einstellung entsprechendes Maß in Vorwärtsoder Rückwärtsrichtung verschoben.According to a further embodiment, the operating control unit in a stroboscopic mode is expediently displaceable into a switching state in which it produces a control signal which acts on at least one luminaire and has a pulse sequence with adjustable phase shift between the control clock and the machine cycle is generated in the luminous area of the luminaire. By means of such a phase shift, which may be negative or positive, a standing appearing object or product is moved in its movement position by an amount corresponding to the setting in the forward or reverse direction.
In besonders bevorzugter Gestaltung ist die Betriebs-Steuereinheit so ausgebildet, daß sie ein wenigstens eine Leuchte ansteuerndes Steuersignal mit einem Puls/Pausen-Verhältnis einer Pulsfolge erzeugt, das bei im Leuchtbereich der Leuchte sich ändernden Maschinentakt unabhängig von einer solchen Änderung konstant gehalten wird. Man erreicht damit, daß die Lichtstärke der Leuchte bei unterschiedlichen bzw. sich auch in großem Maß ändernden Maschinengeschwindigkeiten, z.B. beim Abbremsen oder Beschleunigen, konstant bleibt.In a particularly preferred embodiment, the operating control unit is designed so that it generates a control signal driving at least one lamp with a pulse / pause ratio of a pulse sequence, which is kept constant regardless of such a change in changing machine cycle in the luminous range of the lamp. It is thus achieved that the light intensity of the luminaire at different or even greatly varying machine speeds, e.g. when braking or accelerating, remains constant.
Um zweckmäßig und vorteilhaft die Lichtstärke von Stroboskoplicht und/oder Dauerlicht in einem vorgegebenen Bereich variabel einstellbar zu machen, wird die Betriebs-Steuereinheit in erfindungsgemäßer Ausgestaltung so geschaltet, daß sie ein wenigstens eine Leuchte ansteuerndes Steuersignal mit einem Puls/Pausen-Verhältnis einer Pulsfolge erzeugt, das in einem vorgegebenen Bereich variabel einstellbar ist.To expedient and advantageous to make the light intensity of stroboscopic and / or continuous light variably adjustable in a predetermined range, the operation control unit is switched in the inventive embodiment so that it generates at least one light-driving control signal with a pulse / pause ratio of a pulse train , which is variably adjustable in a predetermined range.
Besonders zweckmäßig und vorteilhaft wird die Betriebs-Steuereinheit der Leuchteneinrichtung in elektrischer Schaltung mit einer zentralen Antriebssteuerung einer mit den Leuchten ausgestatteten Produktionsmaschine verbunden, um die Leuchten nach Maßgabe und/oder in Abhängigkeit von Betriebszuständen der Produktionsmaschine zu steuern. Die Betriebs-Steuereinheit ist dann mit einer elektronischen Trigger-Schaltung ausgestattet, mit der wenigstens eine und vorzugsweise jede Leuchte in Stroboskop-Betriebsart selbsttätig mit dem der jeweiligen Beleuchtungsstelle zugeordneten Maschinentakt angesteuert wird. Mit den an den Systemtakt des Antriebssystems und an die damit möglichen Taktuntersetzungen gekoppelten Leuchten lassen sich Einzelantriebe mit zugehörigen Maschinenorganen individuell beobachten und einstellen. Es werden unbeeinflußt bzw. unabhängig von einer Änderung der jeweiligen Maschinengeschwindigkeit stehende Bilder erzeugt. Zeitgleich lassen sich Bewegungsvorgänge an mehreren Stellen einer Produktionsmaschine besonders gut sowohl in Beschleunigungsphase als auch in Bremsphase beobachten.Particularly expedient and advantageous, the operating control unit of the lighting device is connected in electrical circuit with a central drive control of a production machine equipped with the lights to control the lights in accordance with and / or in dependence on operating conditions of the production machine. The operating control unit is then equipped with an electronic trigger circuit with which at least one and preferably each light in stroboscopic mode is automatically activated with the machine clock associated with the respective lighting location. With the lights coupled to the system clock of the drive system and to the thus possible clock reductions, individual drives with associated machine elements can be individually monitored and adjusted. Unaffected or independent of a change in the respective machine speed, images are generated. At the same time, motion processes at several points of a production machine can be observed particularly well both in the acceleration phase and in the braking phase.
Zweckmäßig kann die Betriebs-Steuereinheit der Leuchteneinrichtung in elektrischer Schaltung auch mit Bedienelementen einer Bedienstation einer Produktionsmaschine zum individuellen Steuern der Leuchten verbunden sein. Zum Beispiel kann zur besonderen Einstellung in einer Stroboskop-Betriebsart ein Mulden- oder Trommeltakt sowie die zu beobachtende Baugruppe bzw. Trommel angewählt werden. In einer Zigarettenstrangmaschine wird zum Beispiel ein vorderer oder hinterer Strang angewählt, um ein stehendes Bild der Zigaretten eines Stranges bei einer Doppelstrangmaschine zu erhalten. Eine Produktionsmaschine wird zweckmäßg mit einem Handrad als Bedienelement ausgestattet, um im Bedarfsfall den Stroboskoplichtbetrieb mit einer Machinen-Betriebsvisualisierung einzuschalten und Einstellungen komfortabel durchzuführen.Expediently, the operating control unit of the lighting device can also be connected in an electrical circuit to operating elements of an operating station of a production machine for individually controlling the lights. For example, for special setting in a stroboscopic mode, a tray or drum clock as well as the module or drum to be monitored can be selected. For example, in a cigarette rod maker, a front or back strand is selected to obtain a still image of the cigarettes of a strand in a double-strand machine. A production machine is zweckmäßg equipped with a handwheel as a control to turn on, if necessary, the stroboscopic light operation with a machine operating visualization and perform settings comfortable.
Zweckmäßig weist eine erfindungsgemäße Leuchteneinrichtung wenigstens eine besonders angepaßte und vorteilhafte Leuchte auf, die wenigstens einen stabförmigen, sich lang erstreckenden Sockel umfaßt, dessen der Leuchten-Abstrahlseite zugewandte Oberfläche als eine eine Schrägung aufweisende Befestigungsfläche ausgebildet ist, an der mehrere Leuchtdioden in Reihe längs des Sockels mit der Schrägung entsprechender Abstrahlausrichtung angeordnet sind. Diese Leuchte baut besonders kompakt, wobei sie eine optimale Ausleuchtung längs eines zu beleuchtenden Maschinenorgans gewährleistet. Besonders vorteilhaft kann die Leuchte ein stabförmiges, sich lang erstreckendes Gehäuse mit wenigstens einem in dessen Längsrichtung sich erstreckenden Montageraum umfassen, der in einen den Dioden-Befestigungssockel aufnehmenden Raum und einen längs mit diesem sich erstreckenden Raum unterteilt ist, in dem wenigstens eine elektronische Einheit zur Leuchtensteuerung angeordnet werden kann.Suitably, a luminaire device according to the invention comprises at least one particularly adapted and advantageous luminaire, which comprises at least one rod-shaped, long-extending pedestal whose surface facing the luminaire radiation side is designed as a mounting surface having a bevel, at which a plurality of light-emitting diodes in series along the base are arranged with the skew corresponding Abstrahlausrichtung. This luminaire is particularly compact, ensuring optimum illumination along a machine organ to be illuminated. Particularly advantageously, the lamp may comprise a rod-shaped, long-extending housing having at least one mounting space extending in its longitudinal direction, which is subdivided into a space accommodating the diode mounting base and a space extending longitudinally therewith, in which at least one electronic unit for Luminaire control can be arranged.
Im ganzen steht erfindungsgemäß eine Leuchteneinrichtung an einer Hochgeschwindigkeits-Produktionsmaschine zum Herstellen von Produkten der Tabak verarbeitenden Industrie zur Verfügung, die mit einer besonderen, mit den Halbleiterlichtquellen aufweisenden Leuchten elektrisch verbundenen, als elektronischer Lichtschalter arbeitenden Betriebs-Steuereinheit ausgestattet ist, die die Leuchten ansteuernde, Pulssignale umfassende Steuersignale hervorbringt. Mittels der Pulssignale werden ausgewählte Leuchten in wahlweise einstellbarem Betrieb mit Dauerlicht und entsprechend dem Maschinensteuertakt mit periodisch unterbrochenem Stroboskoplicht zum Erzeugen von scheinbaren, die Bewegungsabläufe von Maschinenorganen und/oder Produkten darstellenden Bildern versetzt. Zweckmäßig und vorteilhaft ist in wenigstens einer Betriebsart das Puls/Pausen-Verhältnis des jeweils ansteuernden Steuersignals zur Steuerung der Lichtstärke veränderbar. Als Licht emittierende Leuchtelemente sind nicht nur Leistungs-Halbleiterlichtquellen, sondern auch zum Dauerlichtbetrieb und in Verbindung mit Pulssteuerung entsprechend betreibbare Lichtquellen geeignet.On the whole, according to the invention, there is a luminaire device on a high-speed production machine for manufacturing tobacco industry products which is electrically connected to a special luminaire connected to the semiconductor light sources and operates as an electronic light switch, which drives the luminaires. Pulse signals produces comprehensive control signals. By means of the pulse signals selected lights in either adjustable operation with continuous light and according to the machine control clock with periodically interrupted strobe light for generating apparent, the movements of machine organs and / or products representing images. Expediently and advantageously, the pulse / pause ratio of the respectively controlling control signal for controlling the light intensity can be changed in at least one operating mode. As light emitting light elements not only power semiconductor light sources, but also for continuous light operation and in conjunction with pulse control corresponding operable light sources are suitable.

Eine erfindungsgemäße Leuchteneinrichtung 2, wie sie in Fig. 2 dargestellt ist, umfaßt ein System von Leuchten L1 bis L9, von denen drei Leuchten L1 bis L3 an einer Zigarettenstrangmaschine 1 gemäß Fig. 1 ortsfest angeordnet sind. Die Leuchte L1 ist an einem Druckwerk 1.23, die Leuchte L2 an einem Messerapparat 1.31 und die Leuchte L3 an einer Schnittstelle 1.35 zwischen der Zigarettenstrangmaschine 1 und einer Filteransetzmaschine 1.37 vorgesehen. Die Leuchteneinrichtung 2 weist eine Betriebs-Steuereinheit (Ansteuereinheit) 3 auf. Bestandteil der Steuereinheit 3 ist eine in Fig. 1 dargestellte, zweckmäßig mikroprozessor-gesteuerte Ansteuerelektronik in Form einer Triggersteuerung 31, die mit einem oder mehreren Maschinen-geschwindigkeitsabhängigen Signalen einer Maschinen-Antriebssteuerung 11 versorgt wird. So werden die Leuchten L1 bis L9 mit zugeordneten, eine Pulsfolge aufweisenden Steuersignalen S1 bis S9 entsprechend dem Maschinentakt bzw. entsprechend dem die Maschine steuernden Takt MT beaufschlagt.A luminaire device 2 according to the invention, as shown in FIG. 2, comprises a system of luminaires L1 to L9, of which three luminaires L1 to L3 are arranged in a stationary manner on a cigarette rod machine 1 according to FIG. The luminaire L1 is provided at a printing unit 1.23, the lamp L2 at a knife apparatus 1.31 and the lamp L3 at an interface 1.35 between the cigarette rod maker 1 and a filter attachment machine 1.37. The luminaire device 2 has an operating control unit (drive unit) 3. Component of the control unit 3 is shown in Fig. 1, expedient microprocessor-controlled control electronics in the form of a
Gemäß Ausführungsbeispiel der Fig. 3 und 4 ist jede Leuchte L1 bis L9 durch eine Gruppe von zehn lichtemittierenden Leistungs-Leuchtdioden LED gebildet. Solche Dioden sind handelsüblich und z.B. mit einer Leistung von einem Watt erhältlich. Wie aus Fig. 4 ersichtlich, ist jede Leuchtdiode auf einer kleinen rechteckförmigen Platine 6 angeordnet, die auch eine Dioden-zugehörige elektronische Dioden-Steuerschaltung 4 aufnimmt. Jede Diode erzeugt homogenes und farbloses (neutrales) Licht.According to the embodiment of FIGS. 3 and 4, each luminaire L1 to L9 is formed by a group of ten light emitting power LED's. Such diodes are commercially available and e.g. available with a power of one watt. As can be seen from FIG. 4, each light-emitting diode is arranged on a small rectangular circuit board 6, which also accommodates a diode-associated electronic diode control circuit 4. Each diode produces homogeneous and colorless (neutral) light.
Üblicherweise ist eine Produktionslinie zum Herstellen von Zigaretten durch eine Zigarettenstrangmaschine, eine Filteransetzmaschine und eine anschließende Verpackungsmaschine bestimmt. Solche taktgesteuerten, kontinuierlich arbeitenden Produktionsmaschinen sind bekannt und zum Beispiel in
Mit den fest an der Maschine 1 installierten Leuchten L1, L2 und L3 werden wahlweise das Druckwerk 1.23, der Messerapparat 1.31 und die Übergabestelle 1.35 zwischen den Maschinen 1 und 1.37 mit Dauerlicht beleuchtet. Andererseits sind ein und dieselben Leuchten L1 bis L3 mittels der erfindungsgemäßen Einrichtung wahlweise auf Stroboskop-Betriebsarten umschaltbar, um besonders einfach und präzise eine exakte Einhaltung des Druckbildes, des Trennschnitts sowie eine einwandfreie Übergabe von Zigaretten 1.32 auf die Filteransetzmaschine 1.37 nicht nur zu überwachen, sondern auch einzustellen. Dabei bleiben Schutzabdeckungen an der Maschine 1 geschlossen.With the lights L1, L2 and L3 permanently installed on the machine 1, either the printing unit 1.23, the knife apparatus 1.31 and the transfer point 1.35 between the machines 1 and 1.37 are illuminated with permanent light. On the other hand, one and the same lights L1 to L3 by means of the device according to the invention optionally switched to stroboscope modes to particularly simple and precise exact compliance with the printed image, the separation section and a proper transfer of cigarettes 1.32 on the filter attachment 1.37 not only to monitor, but also to adjust. Protective covers on the machine 1 remain closed.
Die Betriebs-Steuereinheit 3 gemäß Fig. 2 ermöglicht für sämtliche Leuchten L1 bis L9 universellen und multifunktionellen Betrieb. Die Steuereinheit 3, die mit einer Gleichspannung U0 von z.B. 24 V versorgt wird, arbeitet als Betriebsarten einstellender bzw. bestimmender elektronischer Lichtschalter sowie als elektronische Triggerschaltung. Jede Leuchte L1 bis L9 wird über einen Spannungsausgang der Steuereinheit 3 mit Gleichspannung U1 von z.B. 24 V versorgt, und die Spannung bzw. Leistung jeder Leuchte L1 bis L9 ist mit individuellem Takt-Steuersignal S1 bis S9 steuerbar, das die Steuereinheit 3 in Abhängigkeit von gewählter und eingestellter Licht-Betriebsart hervorbringt. Als Ausgangstreiber wird ein handelsüblicher Differenztreiber verwendet.The operation control unit 3 according to FIG. 2 enables universal and multifunctional operation for all lights L1 to L9. The control unit 3, which is supplied with a DC voltage U0 of, for example 24 V, operates as a mode adjusting or determining electronic light switch and as an electronic trigger circuit. Each lamp L1 to L9 is supplied via a voltage output of the control unit 3 with DC voltage U1 of eg 24 V, and the voltage or power of each lamp L1 to L9 is controllable with individual clock control signal S1 to S9, the control unit 3 in response to selected and set light mode yields. The output driver is a commercially available differential driver.
Die Signale werden mit 5 V-Differenzsignal übertragen. In dem Diagramm der Fig. 2 wird die Signalübertragung mit einem Steuersignal S, wie es mit nebeneinander auftretenden Signalen S1 bis S9 für zugehörige Leuchten L1 bis L9 unterschiedlich hervorgebracht werden kann, über eine einzige Steuerleitung dargestellt. Unterschiedliche Signale S1 bis S9 können im Multiplex-Betrieb über mehrere logische Kanäle über eine einzige Leitung, oder, wie in Fig. 1 dargestellt, mit jeweils zugeordneten Leitungen übertragen werden. Das Steuersignal S bzw. die Steuersignale S1 bis S9 enthalten eine bzw. mehrere periodische Pulsfolgen mit Pulsfrequenz PF. Jede Dioden-Steuerschaltung 4 ist so vorbereitet und geschaltet, daß die Ansteuerung mit steigenden Flanken der Pulse P ausgelöst wird, um die Dioden der Leuchten L1 bis L9 mit entsprechend den Pulssignalen getakteter Spannung zu versorgen.The signals are transmitted with 5 V differential signal. In the diagram of Fig. 2, the signal transmission with a control signal S, as can be produced differently with adjacent signals S1 to S9 for associated lights L1 to L9, represented by a single control line. Different signals S1 to S9 can be transmitted in multiplex mode over a plurality of logical channels via a single line, or, as shown in Fig. 1, each with associated lines. The control signal S or the control signals S1 to S9 contain one or more periodic pulse sequences with pulse frequency PF. Each diode control circuit 4 is prepared and switched so that the drive is triggered with rising edges of the pulses P to supply the diodes of the lights L1 to L9 with pulsed voltage corresponding to the pulse signals.
Im Ausführungsbeispiel der Fig. 2 kann jede LED-Leuchte L1 bis L9 wahlweise in drei Grundbetriebsarten betrieben werden, und zwar zum Erzeugen von Dauerlicht ohne Ansteuerung, von Dauerlicht mit Ansteuerung sowie von Stroboskoplicht.In the embodiment of FIG. 2, each LED lamp L1 to L9 can be operated optionally in three basic modes, namely for generating continuous light without control, of continuous light with control and strobe light.
In der Dauerlicht-Betriebsart ohne Ansteuerung überträgt die Signalsteuerleitung kein Steuersignal S. Die Dioden-Steuerschaltung 4 jeder Leuchte L1 bis L9 diskriminiert das Vorhandensein bzw. Nicht-Vorhandensein eines Steuer-Taktsignals S und schaltet dementsprechend zwischen getakteter und direkter ungetakteter Leuchdioden-Spannungsversorgung selbsttätig um. Jede Leuchte L1 bis L9 ist mit Diode und individueller Dioden-Steuerschaltung 4 so ausgelegt und geschaltet, daß sie bei Ausbleiben des Takts des Steuersignals S direkt mit Gleichspannung U1 von typischerweise 24 V betrieben wird.In the steady light mode without control, the signal control line does not transmit a control signal S. The diode control circuit 4 of each lamp L1 to L9 discriminates the presence or absence of a control clock signal S and accordingly switches automatically between clocked and direct uncaged light-emitting diode power supply , Each lamp L1 to L9 is designed with diode and individual diode control circuit 4 and connected so that it is operated directly to DC voltage U1 of typically 24 V in the absence of the clock of the control signal S.
In der Betriebsart "Dauerlicht mit Ansteuerung" wird die elektrische Leistung gesteuert, um die Leuchten-Lichtstärke zu ändern und einzustellen. Die Leuchte wird als Dimmer betrieben. Zu diesem Zweck wird ein Steuersignal S erzeugt, dessen Pulsfrequenz PF zur Frequenz des Maschinensteuertakts MT im Leuchtbereich der jeweils gesteuerten LED-Leuchte L1 bis L9 asynchron ist. Berücksichtigt man, daß der Hochgeschwindigkeits-Maschinentakt mit einer Frequenz in der Größenordnung von 200 Hz bis 400 Hz erzeugt wird, so wird zweckmäßig eine Pulsfrequenz PF oberhalb 450 Hz gewählt. Zur Steuerung der Lichtstärke wird das Puls/Pausen-Verhältnis P/P der Pulsfolge geändert und eingestellt; Änderung und Einstellung erfolgen zweckmäßig im Bereich 1/2 < P/P < 99/1. So ist die Lichtstärke der angewählten Leuchte stufenlos einstellbar. Dies ist von besonderer Bedeutung, um Dauerlicht-Beleuchtung zur Vermeidung von Blendeffekten an zu beobachtende Objekte anzupassen.In the "continuous light with control" operating mode, the electrical power is controlled to change and adjust the luminaire luminous intensity. The lamp is operated as a dimmer. For this purpose, a control signal S is generated whose pulse frequency PF is asynchronous to the frequency of the machine control clock MT in the luminous range of the respectively controlled LED lamp L1 to L9. Considering that the high-speed machine cycle is generated with a frequency in the order of 200 Hz to 400 Hz, it is expedient to choose a pulse frequency PF above 450 Hz. For controlling the light intensity, the pulse / pause ratio P / P of the pulse train is changed and set; Change and adjustment are expedient in the range 1/2 < P / P <99/1. Thus, the luminous intensity of the selected luminaire is infinitely adjustable. This is of particular importance in order to adapt continuous lighting to avoid glare effects on objects to be observed.
In der dritten Betriebsart schaltet die Betriebs-Steuereinheit 3 auf Stroboskop-Betrieb um. Die entsprechend angesteuerte Leuchte strahlt periodisch unterbrochenes Licht ab. Um ein scheinbar stillstehendes Bild des zu messenden Vorgangs zu erzeugen, wird die Steuereinheit 3 in einen Schaltzustand versetzt, in dem sie ein Steuersignal S erzeugt, dessen Pulsfrequenz synchron mit dem Maschinen-Steuertakt MT im Leuchtbereich der angesteuerten LED-Leuchte gehalten wird. Um aus der Position des stehend erscheinenden Objekts eine langsame Bewegung des Objekts in oder gegen die Laufrichtung in der Maschine zu erhalten, läßt sich die Betriebs-Steuereinheit 3 in einen Schaltzustand versetzen, in dem sie ein Steuersignal S hervorbringt, das mit einem von Takt-Synchronität des Steuertakts mit dem Maschinensteuertakt MT im Leuchtbereich der angesteuerten LED-Leuchte abweichenden, einstellbaren Takt-Offset OS erzeugt wird. Gemäß der gewünschten Bewegungs-Beobachtungsrichtung wird ein geringfügiger Versatz der Frequenz von der Synchronität nach oben oder nach unten eingestellt.In the third mode, the operation control unit 3 switches to stroboscopic operation. The correspondingly controlled luminaire emits periodically interrupted light. In order to produce a seemingly stationary image of the process to be measured, the control unit 3 is placed in a switching state in which it generates a control signal S whose pulse frequency is kept in synchronism with the engine control clock MT in the luminous range of the driven LED light. In order to obtain a slow movement of the object in or against the running direction in the machine from the position of the object which appears to be stationary, the operating control unit 3 can be set to a switching state in which it produces a control signal S which corresponds to one of the clock signals. Synchronicity of the control clock with the machine control clock MT in the luminous range of the driven LED light deviating, adjustable clock offset OS is generated. According to the desired motion-observation direction, a slight offset of the frequency from the synchronism is set up or down.
Weiterhin ist die Betriebs-Steuereinheit 3 derart ausgebildet und geschaltet, daß die Pulsfolge des Steuersignals S in ihrer Phasenlage verschiebbar und einstellbar ist. Ausgehend von einem bei Frequenzsynchronität stehend erscheinenden Objekt kann dieses entsprechend einer Vor- oder Rückverstellung der Phase in seinem Lauf nach vom oder hinten verschoben werden.Furthermore, the operation control unit 3 is designed and connected such that the pulse sequence of the control signal S is displaceable and adjustable in its phase position. Starting from an object appearing at frequency synchrony, it can be shifted in or out of its course according to a forward or backward adjustment of the phase.
Während im Betrieb der Steuereinheit 3 mit in der Lichtstärke veränderbarem Dauerlicht das Puls/Pausen-Verhältnis P/P zum Ausleuchten mit unterschiedlicher Lichtstärke geändert wird, ist die Steuereinheit 3 für den Stroboskoplichtbetrieb so vorbereitet und geschaltet, daß das Puls/Pausen-Verhältnis P/P, das sich an sich mit Änderung der Pulsfrequenz ändert, bei Pulsfrequenzänderung konstant gehalten wird. Auch dadurch erreicht man eine zusätzliche wesentliche Qualitätsverbesserung der Ausleuchtung bzw. Messung mit Stroboskoplicht. Eine weitere Eigenschaft der Betriebs-Steuereinheit 3 besteht darin, daß auch die Lichtstärke des Stroboskoplichts durch Ändern und Verstellen des Puls/Pausen-Verhältnisses P/P kontinuierlich veränderbar und einstellbar ist, wobei die Konstanthaltung in bezug auf sich ändernde Pulsfrequenz PF beibehalten bleibt. Zweckmäßig wird ein Puls/Pausen-Verhältnis P/P im Bereich von 1/99 < P/P < 1/2 eingestellt. Dabei weist die Steuereinheit 3 die Eignung auf, daß Stroboskoplicht in einem weiten Frequenzspektrum von insbesondere 3 bis 400 Hz hervorbringbar ist.While the pulse / pause ratio P / P for illuminating with different light intensity is changed during operation of the control unit 3 with continuous light variable in the light intensity, the control unit 3 for the stroboscopic light operation is prepared and switched such that the pulse / pause ratio P / P, which changes per se with change of the pulse rate, is kept constant at pulse frequency change. This also achieves an additional significant quality improvement of the illumination or measurement with stroboscopic light. Another feature of the operation control unit 3 is that the light intensity of the strobe light is continuously changeable and adjustable by changing and adjusting the pulse / pause ratio P / P, wherein the constant maintenance with respect to changing pulse frequency PF is maintained. Suitably, a pulse / pause ratio P / P is set in the range of 1/99 <P / P <1/2. In this case, the control unit 3 on the suitability that stroboscopic light in a wide frequency spectrum of particular 3 to 400 Hz can be brought out.
Man erkennt, daß anhand der beschriebenen Betriebsarten ein Maximum an Einstellmöglichkeiten und Flexibilität zum Ausleuchten, Messen, Analysieren und/oder Einstellen des Produktlaufs bzw. der Maschinenorgane mit ein und demselben Leuchtmittel erreicht wird. Um die Einstellungs- und Beobachtungsbandbreite optimal zu nutzen, ist die Betriebs-Steuereinheit 3 mit der Antriebssteuerung 11 der mit dem Leuchtensystem ausgestatteten Produktionsmaschine elektrisch verbunden und geschaltet. Die Maschinen-Antriebssteuerung 11 ihrerseits wird üblicherweise durch eine Speicher-programmierbare Steuerung 12 verwaltet und betrieben. Gemäß installierter bzw. einstellbarer Programme werden insbesondere Zustände von Bedienelementen und/oder Maschinensensoren abgefragt und zugeordnete Vorgänge gesteuert. Insbesondere wird erfindungsgemäß erreicht, daß die multifunktionelle Leuchteneinrichtung 2 in Kombination mit einer Maschinenvisualisierung, also in Verbindung mit den Maschinenzustand und/oder - betrieb visualisierenden Bedienfeldern betrieben wird. Im Bedarfsfall kann mittels eines Maschinenbedienelements wie eines Handrades zusammen mit der Maschinenvisualisierung Dauerlichtbetrieb und Stroboskopbetrieb eingeschaltet und eingestellt werden. Unter Nutzung der mit der Steuereinheit 3 geschalteten Steuerungen 11, 12 kann dann zum Beispiel gezielt ein Mulden- oder Trommeltakt sowie die zugehörige zu beobachtende Baugruppe oder Trommel angewählt werden, also zum Beispiel in Fig. 1 der durch die Leuchte L3 ausgeleuchtete Bereich der Übernahmetrommel 1.36. Insbesondere kann der Lauf der Übemahmetrommel 1.36 durch Anwendung der beschriebenen Leuchten-Betriebsarten genau beobachtet, analysiert, eingestellt und/oder korrigiert werden. Diese Art der Analyse und Einstellung erlaubt es auch, die Art von Fehlern oder Störungen zuverlässig und schnell einzuordnen, nämlich insbesondere zwischen elektrischen Systemfehlem und Prozeßfehlern im Bereich von Einzelantrieben abzugrenzen und zu unterscheiden. Derartige Beobachtungen, Messungen und Einstellungen können aufgrund der systematischen Beleuchtung an mehreren Stellen in der Maschine in bezug aufeinander durchgeführt werden. Mittels der Steuereinheit 3 in Verbindung mit den Steuerungen 11, 12 sind die Leuchten L1 bis L9 im Stroboskopbetrieb an den Systemtakt MT des Maschinen-Antriebssystems, gegebenenfalls jeweils mit zugeordneter Taktuntersetzung gekoppelt. Die Steuereinheit 3 ist so eingerichtet, daß bei Stillstand der Produktionsmaschine automatisch von Stroboskopbetrieb auf Dauerbeleuchtung umgeschaltet wird. Dabei kann zunächst die Betriebsart "Dauerlicht ohne Ansteuerung" selbsttätig eingeschaltet werden und dann im Bedarfsfall in der Betriebsart "Dauerlicht mit Ansteuerung" die Lichtstärke verringert bzw. angepaßt werden, um an gewünschter Stelle eine reflexions- und blendfreie Beobachtung zu gewährleisten. Selbstverständlich ist es aber auch möglich, während des Laufs der Produktionsmaschine auf Dauerlicht in den genannten Betriebsarten umzuschalten, um gewünschte Innenbereiche in der Maschine auszuleuchten.It can be seen that a maximum of setting options and flexibility for illuminating, measuring, analyzing and / or adjusting the product run or the machine elements with one and the same light source is achieved on the basis of the operating modes described. In order to make optimum use of the adjustment and observation bandwidth, the operation control unit 3 is electrically connected and switched to the
Der Einsatz der erfindungsgemäßen Leuchteneinrichtung an mit Hochgeschwindigkeit arbeitenden Maschinen der Tabak verarbeitenden Industrie ist grundsätzlich unbegrenzt. Insbesondere wird die erfindungsgemäße Leuchteneinrichtung auch an der der beschriebenen Zigarettenstrangmaschine 1 nachfolgenden Filteransetzmaschine 1.37 angeordnet, und zwar dort ebenfalls an schwer zugänglichen, einstellkritischen Stellen, insbesondere über dem Bereich von Trommelübergabestellen, Schneidtrommeln, Filterstaffeltrommeln, Filterschiebetrommeln, Beleimungseinrichtungen, Taumeltrommeln, Rolltrommeln, Roll- und Wendemitteln und Abbremstrommeln. Auch eine Zigarettenpackmaschine, die im Massenstrom Zigaretten von der Filteransetzmaschine 1.37 erhält, wird zweckmäßig mit der erfindungsgemäßen Leuchteneinrichtung ausgestattet. Insbesondere werden die Leimbildkontrolle im Papierlauf, der Schnitt an der Rolltrommel, die Lage und/oder Bewegung des Produkts auf den Trommeln und Mulden sowie der Filterlauf überwacht und eingestellt. Man erkennt, daß praktisch alle betriebs- und/oder einstellkritischen Stellen einer Zigaretten-Produktionslinie mittels erfindungsgemäßer Leuchteneinrichtung unter Nutzung der gesteuerten multifunktionellen oder hybriden Lichtfunktionen ein und derselben Lichtquellen eingesetzt werden können.The use of the luminaire device according to the invention on high-speed machines of the tobacco-processing industry is basically unlimited. In particular, the luminaire device according to the invention is also arranged on the described cigarette rolling machine 1 subsequent Filteransetzmaschine 1.37, there also in hard to reach, critical points, especially on the range of drum transfer points, cutting drums, Filterstaffeltrommeln, Filterschiebedrommeln, gluing equipment, tumbling drums, roller drums, rolling and Wringing and deceleration drums. A cigarette packaging machine, which receives cigarettes from the Filteransetzmaschine 1.37 in mass flow, is expediently equipped with the lighting device according to the invention. In particular, the glue image control in the paper run, the cut on the roller drum, the position and / or movement of the product on the drums and troughs and the filter run are monitored and adjusted. It can be seen that virtually all operational and / or critical adjustment points of a cigarette production line can be used by means of inventive lighting device using the controlled multifunctional or hybrid light functions of one and the same light sources.
Wie aus Fig. 3 und 4 ersichtlich, umfaßt eine Diodenleuchte L1 einer erfindungsgemäßen Leuchteneinrichtung - die Leuchten L2 bis L9 sind entsprechend ausgebildet - ein stabförmiges, sich lang erstreckendes rechteckförmiges Gehäuse 5. Das Gehäuse 5 nimmt, getrennt durch einen mittleren Raum 52 zur Kabelaufnahme, zwei gleiche stabförmige Sockel 51 auf, die sich mit dem Gehäuse 5 lang erstrecken. Jeder Sockel 51 weist eine Oberfläche auf, die als der Leuchten-Abstrahlseite zugewandte Schrägfläche 510 ausgebildet ist. An dieser sind in Reihenanordnung fünf jeweils die Diode LED, zugehörige Dioden-Steuerschaltung 4 und Platine 6 aufweisende Leuchtdiodeneinheiten befestigt. Man erhält dadurch eine der Schrägung entsprechende Abstrahlausrichtung. Jeder Schrägsockel 51 ist in einem in bezug auf die Gehäusebreite B oberen Raumbereich 53 des Gehäuses 5 angeordnet, während unterhalb des tieferen Teils des Schrägsockels 51 ein Gehäuseraum 54 zur Verfügung steht, der bei Bedarf zur Unterbringung einer elektronischen Schaltung genutzt werden kann. Die Sockelschräge ist mit 25° derart gewählt, daß man einen außermittigen Abstrahl- bzw. Lichtöffnungswinkel von wenigstens α =110° erhält. An der Gehäusevorderseite ist eine lichtdurchlässige Fenster-Schutzabdeckung angebracht. Die gemäß Fig. 3 und 4 in der beschriebenen Ausführungsform dargestellte Leuchte baut besonders klein und kann daher bequem in engem Raum an der zu beleuchtenden Stelle untergebracht werden. In der Gruppierung mit zweimal fünf Dioden erhält man, trotz Trennung durch den in der Stableuchte mittleren Montagebereich eine sowohl über die Länge der Leuchte als auch in dem Abstrahl-Raumwinkel von α =110° durchgehende, lichtintensive Ausleuchtung mit homogenem weißem Licht, das in den unterschiedlichen Betriebsarten jeder Leuchte für optimale orts- und funktionsangepaßte Beleuchtung sorgt.As can be seen from FIGS. 3 and 4, a diode lamp L1 of a luminaire device according to the invention comprises a rod-shaped, elongated
