Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum optischen Erfassen von Stückgütern und deren Lage auf Transporteinrichtungen, insbesondere von stückartigen Nahrungsmitteln, zur Steuerung stromabwärtiger Greifvorrichtungen.The The invention relates to a device for the optical detection of piece goods and their location on transport facilities, in particular piece-like Foodstuffs, for controlling downstream gripping devices.
Aus
dem Stand der Technik sind eine Reihe solcher Vorrichtungen bekannt.
Beispielsweise zeigt die
Vorteile der ErfindungAdvantages of invention
Es ist, ausgehend von diesem Stand der Technik, Aufgabe der Erfindung, eine Vorrichtung zum optischen Erfassen von Stückgütern anzugeben, die einen modularen kompakten Aufbau aufweist und dabei bei gleichzeitig hoher Tiefenschärfe die Erfassung von flachen bis zu höheren Produkten ermöglicht.It is, starting from this prior art, object of the invention, to provide a device for the optical detection of general cargo, which is a modular has a compact design and at the same time with high depth of field, the Capture from flat to higher Products.
Diese Aufgabe löst eine Vorrichtung mit den Merkmalen des Anspruchs 1.These Task solves a device with the features of claim 1.
Die erfindungsgemässe Abtastvorrichtung weist einen gefalteten Strahlengang auf, so dass sich ein grosser Objekt-Bild Abstand ergibt.The invention Scanning device has a folded beam path, so that a large object-image distance results.
Vorzugsweise sind die Bildabtastvorrichtungen quer zum Förderer eindimensional ausgestaltet, so dass der Bildwinkel klein ist, und somit fast parallele Strahlen vorliegen, ohne dass die Zeilenkameras die vollständige Breite der Transporteinrichtung abdecken müssen.Preferably For example, the image scanning devices are one-dimensionally configured transversely to the conveyor that the image angle is small, and thus almost parallel rays present without the line scan cameras the full width must cover the transport device.
Die hohe Tiefenschärfe der Vorrichtung gestattet den modularen Einsatz derselben bei beliebigen Transporteinrichtungen und dies direkt für unterschiedlichste Produkte, welche sehr flach oder auch sehr hoch sein können, wobei „flache" Produkte eine Höhe von im Allgemeinen unter 5 Millimeter bedeutet und „hohe" Produkte eine Höhe über einem Transportband bis zu beispielsweise 80 oder 100 Millimeter beinhalten können. Diese Bildabtastungsergebnisse sind bei gleicher Montage-Höhe der Vorrichtung gewährleistet, so dass die Vorrichtung modular in der Konstruktion von Verpackungsanlagen eingesetzt werden kann, ohne dass die Vorrichtung speziell auf die verschiedenen zu erfassenden Stückgüter adaptiert zu werden braucht.The high depth of field the device allows the modular use of the same in any Transport equipment directly for a wide range of products, which can be very shallow or very high, with "flat" products having a height of Generally below 5 mm and "high" products mean a height above a conveyor belt for example, may include 80 or 100 millimeters. These Image scan results are at the same mounting height of the device guaranteed making the device modular in the construction of packaging equipment can be used without the device specifically on the adapted to different items to be detected needs to be.
Eine solche Vorrichtung ist zum optischen Erfassen von stückartigen Nahrungsmitteln und deren Lage auf Transporteinrichtungen zur Steuerung stromabwärtiger Greifvorrichtungen in einer Verpackungsanlage der Lebensmittelindustrie hervorragend geeignet.A such device is for optically detecting piece-like Foodstuffs and their location on transport means for controlling downstream gripping devices excellent in a packaging plant of the food industry suitable.
Weitere vorteilhafte Ausführungsformen der erfindungsgemässen Vorrichtung und Varianten mit erfindungsgemässen Verfahren gehen aus den abhängigen Patentansprüchen hervor.Further advantageous embodiments the inventive Device and variants with inventive method go out of the dependent claims out.

Die Beleuchtungs-Körper können insbesondere aus LED's bestehen, welche linear aneinander gereiht sind. Insbesondere können diese auf bedruckten Platinen aufgebracht sein. Vorteilhafterweise sind es weiss abstrahlende LED's. Es können aber auch, in alternativen Ausführungsformen, grüne, rote oder IR-LED's verwendet werden.The Lighting Devices can especially from LEDs exist, which are lined up linearly. In particular, these can be applied on printed circuit boards. Advantageously it knows emitting LEDs. But it can also, in alternative embodiments, green, red or IR LEDs be used.
Die

des Betriebs der Lichtquellen ist der Konstant-Betrieb, welcher
jedoch die Lebensdauer von weissen LED's stark beschränkt, da LED's einem Alterungsprozess unterliegen.
Eine bessere Alternative ist der Stroboskop-Betrieb, welcher neben einer höheren Lebensdauer
auch zu einer geringeren Wärme-Entwicklung
führt.
Der Stroboskop-Betrieb muss mit den Aufnahmen der Zeilen-Kameras
korreliert sein. Infolgedessen kann der Stroboskop-Betrieb derart
definiert sein, dass die LED's
