Abstract
Description
Gegenstand der Erfindung ist ein Verfahren zur Füllgutkon trolle von verschlossenen Tablettenpackungen in Blisterform aus tiefgezogener Kunststoffolie mit einer Versiegelung aus Aluminiumfolie.The invention relates to a method for Füllgutkon trolls of sealed tablet packs in blister form made of deep-drawn plastic film with a seal made of aluminum foil.
Es ist bekannt, Tablettenpackungen während des Füllens auf Vollständigkeit ihres Tabletteninhaltes zu prüfen. Dabei wird die noch offene Tablettenpackung, d.h. die gefüllte tiefgezogene Kunststoffolie mit Licht durchstrahlt und die Entscheidung getroffen, ob die Tablette vorhanden ist oder fehlt. Es ist ferner bekannt, das durchgetretene Licht mit einer Kamera aufzunehmen, um ein gerastertes Grauwertbild zu erzeugen, das mittels Mikrorechner ausgewertet und mit einem Sollwert verglichen wird. Durch diese Methode lassen sich auch gebrochene Tabletten feststellen. Nachteilig ist, daß die Füllgutkontrolle vor dem Versiegeln des Bli sters erfolgt und Fehler danach nicht mehr erkannt werden. Hinzu kommt eine aufwendige Verschleppung des Auswurfs signals, da sich die Auswurfseinrichtung für fehlerhafte Blister erst am Ausgang der Versiegelungseinrichtung be findet.It is known to put tablet packs on while filling Check the completeness of your tablet content. Here the still open tablet pack, i.e. the filled one thermoformed plastic film with light shining through it Decision made whether the tablet is present or is missing. It is also known that the light that has passed through a camera to take a rasterized grayscale image to generate, which is evaluated by means of microcomputers and with a setpoint is compared. Let through this method find broken tablets. Disadvantageous is that the product inspection before sealing the bli sters and errors are no longer recognized afterwards. In addition, there is a complex carryover of the ejection signals, because the ejection device for faulty Blister only at the exit of the sealing device finds.
Es besteht demnach die Aufgabe, ein Verfahren zu schaffen, mit dem der Blister nach seiner Versiegelung auf Vollstän digkeit seines Inhaltes und Unversehrtheit der Tabletten kontrolliert werden kann.So the task is to create a process with which the blister is completely sealed after it has been sealed accuracy of its content and the integrity of the tablets can be controlled.
Die Erfindung löst die Aufgabe dadurch, daß man die Kunst stoffolie mit Infrarotlicht durchstrahlt, das reflektierte Licht mit einem Lichtempfänger abtastet und ein gerastertes Grauwertbild erzeugt, daß Grauwertbild mittels Mikrorechner auswertet und das Ergebnis mit einem Sollwert vergleicht. The invention solves the problem in that the art Illuminated fabric with infrared light that reflected Scans light with a light receiver and a gridded Grayscale image generates that grayscale image using a microcomputer evaluates and compares the result with a target value.
Der Vorteil der Erfindung liegt in der einfachen, treff sicheren Methode, mit der die Vollständigkeit der Packung und die Unversehrtheit der Tabletten nach der Versiegelung der Packung festgestellt und mangelhafte Packungen ausge sondert werden können. Dabei hat sich Infrarotlicht lang welliger als 800 Nanometer, insbesondere Rotlicht im Be reich zwischen 1400 und 1600 Nanometer als brauchbar er wiesen. Die Rasterung der aufgenommenen Bilder kann mit einer Matrix von ca. 400×300 Bildpunkten vorgenommen werden.The advantage of the invention lies in the simple, accurate safe method by which the completeness of the pack and the integrity of the tablets after sealing the pack found and defective packs out can be separated. Infrared light has been around for a long time wavy than 800 nanometers, especially red light in the loading range between 1400 and 1600 nanometers as usable grasslands. The screening of the captured images can be done with a matrix of approx. 400 × 300 pixels will.
