Title
(EN) ABNORMAL TOOL RESTORING APPARATUS
(FR) APPAREIL POUR LA RECUPERATION D'OUTILS ANORMAUX
Abstract
(EN)
An abnormal tool restoring apparatus is formed by providing the same with a teaching point storage means for storing teaching points taught in advance and defining working lines for a tool with respect to a work so that the tool passes the working lines sequentially, and a teaching point to which a tool on these teaching points can be retracted from the work; a means for detecting the occurrence of abnormality of a tool on the working line with respect to the work; and a control means for carrying a control operation so that the tool the occurrence of abnormality of which has been detected by the tool abnormality detecting means is retracted from an abnormality occurrence point to a nearest teaching point to which the tool can be retracted, on the basis of the teaching points stored in the teaching point storage means, by reversing the same tool along a path of the working line for the tool with respect to the work which the tool has already passed, whereby the tool is retracted from the work, and so that a replaced or repaired tool is then advanced up to the point of occurrence of abnormality along the path of the abnormal tool retracted from the work.

Un appareil pour la récupération d'outils anormaux est pourvu d'un moyen d'enregistrement de points d'apprentissage destiné à stocker des points d'apprentissage appris à l'avance et définissant des lignes de travail pour un outil dans le cadre d'un travail, de telle sorte que l'outil passe successivement par les lignes de travail, et un point d'apprentissage auquel un outil passant sur ces points d'apprentissage peut être retiré du travail. L'appareil comporte également un moyen permettant de détecter l'apparition d'anomalies d'un outil sur la ligne de travail par rapport au travail, ainsi qu'un moyen de commande destiné à réaliser une opération de commande telle que l'outil dont l'anomalie a été détectée par le moyen de détection des anomalies d'outils sera retiré d'un point d'apparition de l'anomalie vers le point d'apprentissage le plus proche auquel l'outil peut être retiré, en fonction des points d'apprentissage stockés dans le moyen de stockage des points d'apprentissage, en faisant reculer cet outil le long du trajet de la ligne de travail de l'outil par rapport au travail que l'outil a déjà réalisé. L'outil est alors retiré du travail, et un outil de remplacement ou réparé est ensuite avancé le long du trajet de l'outil anormal retiré du travail, jusqu'au point d'apparition de l'anomalie.
