Title (EN) SEALING PROCESS INSPECTION DEVICE
(FR) DISPOSITIF D'INSPECTION DE PROCEDE D'ETANCHEIFICATION
Abstract:
(EN) In a first object the present invention provides a method for the inspection of the quality of the sealing of a packages and more specifically the method of the present invention allows the on-line inspection of the air-tightness of a package. Said method comprising the following steps of (i) acquiring the noise signal generated by the sealing equipment during the sealing of the package, (ii) analyzing the signal in order to determine the values of at least one physical parameter characterizing the noise signal and (iii) deciding on the quality of the sealing by comparing the determined value to a reference value for said physical parameter.
(FR) La présent invention a trait principalement à un procédé pour l'inspection de la qualité de l'étanchéification d'emballages et de manière plus spécifique le procédé de la présente invention permet l'inspection en ligne de l'imperméabilité à l'air d'un emballage. Ledit procédé comprend les étapes suivantes : (i) l'acquisition d'un signal de bruit généré par le matériel d'étanchéification lors de l'étanchéification de l'emballage ; (ii) l'analyse du signal en vue de la détermination des valeurs d'au moins un paramètre physique caractérisant le signal de bruit et (iii) la détermination de la qualité de l'étanchéification par la comparaison de la valeur déterminée à une valeur de référence pour ledit paramètre physique.
