Abstract

La présente invention concerne un dispositif et un procédé de réglage automatique de la hauteur d'un pied presseur d'une machine à broder. Un arbre d'entraînement (151) est disposé horizontalement sur un côté d'un pied presseur (165). Le pied presseur (165) est entraîné par un bloc d'entraînement (163) du pied presseur. Le bloc d'entraînement (163) du pied presseur est articulé à une bielle de connexion (169) d'entraînement du pied presseur. La bielle de connexion (169) d'entraînement du pied presseur est articulée sur une extrémité d'un levier (162) du pied presseur. Une autre extrémité du levier (162) du pied presseur est entraînée par une came excentrique (157). La came excentrique (157) est installée sur un axe d'articulation (155) d'entraînement du pied presseur. L'arbre d'entraînement (151) est entraîné par un moteur (156). L'arbre d'entraînement (151) entraîne l'axe d'articulation (155) d'entraînement du pied presseur en rotation par l'intermédiaire d'un mécanisme de bielle de connexion à came. Un dispositif de commande commande le moteur (156) en rotation selon un angle de rotation correspondant à une hauteur définie du pied presseur et permet à l'arbre d'entraînement (151) de tourner. Le mécanisme de bielle de connexion à came et l'axe d'articulation (155) d'entraînement du pied presseur sont liés. Lorsque l'axe d'articulation d'entraînement du pied presseur (155) tourne, la came excentrique (157) fixée sur celui-ci tourne et le centre de déplacement du levier du pied presseur (162) est simultanément modifié, entraînant la tige de liaison d'entraînement du pied presseur (169) et le bloc d'entraînement du pied presseur (163) pour ajuster la hauteur du pied presseur. Le dispositif et le procédé de réglage automatique de hauteur d'un pied presseur d'une machine à broder modifient la hauteur du pied presseur en temps opportun selon une forme de mise en œuvre et évitent l'arrêt destiné à un réglage, ce qui permet d'augmenter l'efficacité de la fabrication et la qualité de la fabrication.
