Title
(EN) SYSTEM AND METHOD FOR ANALYZING SHEET INTERLEAVING MATERIAL
(FR) SYSTÈME ET PROCÉDÉ POUR ANALYSER UN MATÉRIAU D'ENTRELACEMENT DE FEUILLES
Abstract
(EN)
Embodiments provide for analyzing interleaving material applied to sheets of material traveling along a conveyor (30, 42, 50). A system is provided that includes a cross - conveyor support frame (54) and a camera system (52) to capture images of the interleaving material upon the sheets. The camera system (52) may optionally include a movable camera head that travels along the support frame (54) to capture images at multiple positions along substantially the entire width of the conveyor. A control module is provided that includes a processor programmed with instructions for analyzing the interleaving material based on the images. In some cases the analyzing includes receiving the images of the interleaving material from the camera system (52), assessing coverage of the interleaving material upon the sheets of material from the images, determining adjustments for application of the interleaving material based on the assessed coverage, and/or communicating the adjustments to an interleaving material applicator (44).
(FR)
Des modes de réalisation de l'invention permettent d'analyser un matériau d'entrelacement appliqué à des feuilles de matériau se déplaçant le long d'un transporteur (30, 42, 50). Un système qui comprend un bâti de support de transporteur transversal (54) et un système de caméra (52) pour capturer des images du matériau d'entrelacement sur les feuilles sont fournis. Le système de caméra (52) peut, facultativement, comprendre une tête de caméra mobile qui se déplace le long du bâti de support (54) afin de capturer des images en de multiples positions sensiblement le long de la totalité de la largeur du transporteur. Un module de commande qui comprend un processeur programmé avec des instructions pour analyser le matériau d'entrelacement sur la base des images est fourni. Dans certains cas, l'analyse comprend la réception des images du matériau d'entrelacement à partir du système de caméra (52), l'évaluation de la couverture du matériau d'entrelacement sur les feuilles de matériau à partir du système de caméra (52), l'évaluation de la couverture du matériau d'entrelacement sur les feuilles de matériau à partir des images, la détermination de réglages pour l'application du matériau d'entrelacement sur la base de la couverture évaluée, et/ou la communication des réglages à un applicateur de matériau d'entrelacement (44).
