Abstract

L’invention concerne un système de commande d’un obturateur agencé en coulissement dans une buse d’injection de matière plastique, comprenant : - un moteur électrique couplé audit obturateur pour l’entraîner en coulissement entre une position d’obturation de la buse et une position d’ouverture maximale de la buse, - un dispositif (2) de commande du moteur, comprenant au moins deux composants intégrés dans une carte électronique de contrôle du moteur, lesdits composants étant choisis parmi :* un composant adapté pour réguler la course de l’obturateur à une première vitesse constante,* un composant adapté pour réguler la course de l’obturateur à une seconde vitesse constante, supérieure à la première vitesse,* un composant adapté pour sélectivement bloquer la course de l’obturateur,- une unité de commande séquentielle comprenant au moins deux voies de commande (30, 31, 32), configurée pour envoyer sélectivement un signal électrique de commande au dispositif (2) par l’une et/ou l’autre desdites voies de commande (30, 31, 32) de telle sorte que :- sous l’effet d’un premier signal envoyé par la première voie de commande (30), l’un des composants est activé, - sous l’effet d’un second signal envoyé par la seconde voie de commande (31), un autre composant est activé Figure pour l’abrégé : Fig 1AThe invention relates to a system for controlling a shutter slidably arranged in a plastic injection nozzle, comprising: an electric motor coupled to said shutter to drive it slidably between a closed position of the nozzle and a maximum opening position of the nozzle, - a device (2) for controlling the engine, comprising at least two components integrated into an electronic engine control board, said components being chosen from: * a component adapted to regulate the stroke of the shutter at a first constant speed, * a component adapted to regulate the travel of the shutter at a second constant speed, greater than the first speed, * a component adapted to selectively block the travel of the shutter, - a sequential control unit comprising at least two control channels (30, 31, 32), configured to selectively send an electrical control signal to the device (2) by one and / or the other of s said control channels (30, 31, 32) such that: - under the effect of a first signal sent by the first control channel (30), one of the components is activated, - under the effect of a second signal sent by the second control channel (31), another component is activated Figure for the abstract: Fig 1A
