Abstract

L'ensemble de commande selon l'invention est destiné à une machine à injecter les matières plastiques comprenant des organes moteurs qui déplacent certaines de ses parties mécaniques, des organes électromécaniques qui servent à contrôler l'alimentation en puissance des organes moteurs, des détecteurs qui sont manoeuvrés par les parties mécaniques mobiles pour contrôler le début ou la fin des séquences, et il est essentiellement caractérisé par le fait qu'il comprend un ensemble de circuits électroniques logiques du type ET ou NAND qui comportent chacun une sortie susceptible de commander une fin ou un début de séquence et qui comportent d'une part deux entrées qui sont reliées à deux circuits à mémoire du type à bascule, l'un de ces circuits à mémoire étant susceptible d'être contrôlé par un signal de début de séquence, l'autre étant susceptible d'être contrôlé par un signal de fin de séquence et d'autre part une entrée qui est connectée à un groupe d'entrées qui appartiennent chacune à un dit circuit logique du type ET ou NAND et reçoivent des signaux validant ou bloquant l'ensemble des circuits ET ou NAND correspondant à ce groupe d'entrées.
