| description | Device for depositing powdered material with concentrated energy, comprising a rotating plate (2) which is driven by a motor (3) and which is provided with a groove (21) suitable for receiving the powder before it is deposited, and a sensor (5) for sensing the rotation speed of the rotating plate, comprising: - an optical sensor (4) for measuring a fill profile value for the powder in the groove (21) and - a control circuit (6) of the motor (3) for receiving a speed measurement value provided by the speed sensor (5) and a measurement value for the fill profile of the powder in the groove, which value is provided by the optical sensor (4), for determining an instantaneous powder flow value as a function of the speed measurement and the powder profile measurement and for controlling the motor (3) as a function of the value of the determined instantaneous flow rate.
Dispositif de dépôt sous énergie concentrée de matière sous forme de poudre, comportant un plateau tournant (2) entrainé par un moteur (3) et muni d'une rainure (21) adaptée à recevoir la poudre préalablement à son dépôt, et un capteur (5) de vitesse de rotation du plateau tournant, Comportant : - un capteur (4) optique pour mesurer une valeur de profil de remplissage de poudre dans la rainure (21), et - un circuit de contrôle (6) du moteur (3) pour recevoir une valeur de mesure de vitesse fournie par le capteur de vitesse (5) et une valeur de mesure de profil de remplissage de poudre dans la rainure, fournie par le capteur optique (4), pour déterminer une valeur de débit instantané de poudre en fonction des mesures de vitesse et de profil de poudre et pour commander le moteur (3) en fonction de la valeur du débit instantané déterminée. |
