Abstract

L'invention concerne un procédé de positionnement d'unités de commande d'un chariot de chargement de charbon sur des ouvertures de chargement d'un four à coke. Un chariot de chargement de charbon sur rails est déplacé sur la voûte d'un four à coke et positionné pour le chargement des chambres du four, à des endroits prédéfinis par une commande machine et affectés à des ouvertures de chargement dans la voûte du four, au moins une unité de commande du chariot de chargement de charbon étant ensuite amenée vers les ouvertures de chargement par des mouvements de réglage horizontaux sur deux axes. Après chaque positionnement du chariot de chargement de charbon, les coordonnées d'au moins un marquage appliqué sur la voûte du four, présentant une affectation fixe par rapport à l'axe central d'une ouverture de remplissage, sont détectées au moyen d'un procédé de mesure optique dans un champ de mesure prédéfini par le procédé de mesure, et comparées à des valeurs de référence enregistrées dans la commande machine pour le marquage. Des écarts entre les coordonnées mesurées et les coordonnées enregistrées sont déterminés pour les deux axes. Des valeurs de différence sont alors prises en compte en tant que valeurs de correction lors du mouvement de réglage de l'unité de commande. L'invention concerne également un dispositif destiné à la mise en oeuvre du procédé.
