Description
Die Erfindung betrifft eine Bogendruckmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a sheet-fed printing machine according to the preamble of
Zur Regelung oder Steuerung des Transport- und Bearbeitungsprozesses einer drucktechnischen Maschine ist es bekannt, fotoelektrische Detektoren zu verwenden, die auf einen Bogen oder eine Bahn gerichtet sind. Die Detektoren arbeiten im Auflicht oder Durchlicht, wobei dann, wenn das Umgebungslicht nicht ausreicht, Beleuchtungsanordnungen mit künstlichen Lichtquellen zum Einsatz kommen.To control or control the transport and processing process of a printing machine, it is known to use photoelectric detectors directed to a sheet or web. The detectors operate in reflected light or transmitted light, in which case when the ambient light is insufficient, lighting arrangements with artificial light sources are used.

Es ist Aufgabe der vorliegenden Erfindung, eine Bogendruckmaschine mit einem Beleuchtungssystem für einen Bedruckstoff zu entwickeln, welches mit geringem Aufwand und kleinem Volumen eine homogene Ausleuchtung entlang einer Linie ermöglicht.It is an object of the present invention to develop a sheet-fed printing machine with an illumination system for a printing material, which enables homogeneous illumination along a line with little effort and with a small volume.
Die Aufgabe wird mit einer Anordnung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object is achieved with an arrangement having the features of
Gemäß der Erfindung wird ein Beleuchtungssystem mit einem länglichen Strahlkörper vorgesehen, wobei an der Stirnseite des Strahlkörpers eine Lichtquelle angeordnet ist und an seiner Längsseite der Lichtaustritt vorgesehen ist. Der Strahlkörper kann als lichtleitender Stab mit Streukörpern ausgeführt sein. Der lichtleitende Stab besteht nicht notwendiger Weise aus einem starren Material. Er kann flexibel ausgeführt und im Querschnitt kreisförmig ausgebildet sein. Andere als ein Kreisformquerschnitt sind möglich. Auf der einem Bedruckstoff abgewandten Seite und auf der von der Lichtquelle abgewandten Stirnseite kann der Strahlkörper eine lichtreflektierende Beschichtung aufweisen. Als Lichtquelle können eine einzelne Lumineszenzdiode oder mehrere Lumineszenzdioden oder ein Laser vorgesehen sein. Die Lichtquelle kann wahlweise kontinuierliches und intermittierendes Licht aussenden. Neben der sensorischen Erfassung des vom Bedruckstoff reflektierenden Lichtes ist die Beleuchtungsanordnung auch für die visuelle Inspektion geeignet. Die Vorteile der Erfindung bestehen in der kompakten Bauform, die an die Gegebenheiten einer Druckmaschine optimal angepasst ist. Weiterhin ist das Beleuchtungssystem kostengünstig herstellbar und besitzt eine zuverlässige Funktionsweise.According to the invention, a lighting system is provided with an elongate jet body, wherein on the front side of the jet body, a light source is arranged and on its longitudinal side of the light exit is provided. The jet body can be designed as a light-conducting rod with scattering bodies. The photoconductive rod is not necessarily made of a rigid material. It can be made flexible and circular in cross-section. Other than a circular cross section are possible. On the side facing away from a printing material and on the end face facing away from the light source, the jet body may have a light-reflecting coating. As the light source, a single light emitting diode or a plurality of light emitting diodes or a laser may be provided. The light source can optionally emit continuous and intermittent light. In addition to the sensory detection of the light reflected from the substrate, the illumination arrangement is also suitable for visual inspection. The advantages of the invention consist in the compact design, which is optimally adapted to the conditions of a printing press. Furthermore, the lighting system is inexpensive to produce and has a reliable operation.
