Abstract

La présente invention concerne un système de transfert de matériau d'une presse de grande taille et, plus spécifiquement, l'objectif de la présente invention est d'améliorer largement l'efficacité de transfert de matériau et la productivité en transférant simultanément des matériaux à l'aide d'un dispositif de transport de matériau optimisé pour un processus (chaîne) de presse d'une presse de grande taille, dans lequel une pluralité de moules supérieurs et inférieurs sont alignés et prévus à des intervalles prédéfinis de manière à poinçonner et à former la pluralité de matériaux pour chaque processus (ou une unité de traitement) à la fois. La présente invention comprend : un dispositif de fourniture de matériau (3) destiné à charger la pluralité de matériaux (2) à une hauteur prédéfinie ; un dispositif de transfert de matériau (6) pour transporter les matériaux (2) vers les moules inférieurs (5) de la presse de grande taille (4) et en retour ; la pluralité de moules inférieurs (5) et de moules supérieurs (7), au nombre d'au moins deux, respectivement, fournis sous forme de paire au niveau des parties supérieure et inférieure de la presse de grande taille (4) et alignés successivement de manière à poinçonner la pluralité de matériaux en même temps par poinçonnage et formage simultanés de ceux-ci ; le dispositif de transport de matériau (8) prévu au niveau de l'arrière de la presse de grande taille (4) qui transfère la pluralité de matériaux, ayant été simultanément poinçonnés par la pluralité de moules supérieurs et inférieurs (5, 7) vers les moules inférieurs du traitement ultérieur tout en se déplaçant sur les axes X, Y et Z ; et un dispositif de décharge de matériau (9) pour décharger, vers un transporteur de décharge (10), le matériau formé dans le moule positionné au niveau de l'extrémité de la presse de grande taille (4).
