Abstract

Dispositif de levage. L’invention concerne un dispositif de levage d’une bobine et un dérouleur comportant un tel dispositif de levage. Dispositif de levage (1) d’un axe de déroulement (20) d’un dérouleur de bobine (2), l’axe de déroulement (20) se poursuivant perpendiculairement à une extrémité par une première barre (21) pivotant autour d’un premier axe (OO’), ledit dispositif de levage (1) comportant des moyens d’actionnement en pivotement (4) de la première barre (21) autour du premier axe (OO’), un vérin (40) relié par une extrémité à la structure (3), les moyens d’actionnement en pivotement (4) comportant un levier (5) pivotant autour d’un second axe (AA’) décentré par rapport au premier axe (OO’) et un bras (6) pivotant autour du même second axe (AA’), l’extrémité distale (51) dudit levier (5) étant connectée au vérin (40), les extrémités proximales (50, 60) du levier (5) et du bras (6) étant solidaires et pivotantes selon le second axe (AA’), l’extrémité distale (61) du bras (6) comportant des moyens de guidage en pivotement (7) de la première barre (21) lors de l’actionnement du vérin (40). Figure pour l’abrégé : Fig. 2Lifting device. The invention relates to a device for lifting a reel and an unwinder comprising such a lifting device. Device for lifting (1) an unwinding axis (20) of a reel unwinder (2), the unwinding axis (20) continuing perpendicularly at one end by a first bar (21) pivoting about a first axis (OO '), said lifting device (1) comprising pivotal actuation means (4) of the first bar (21) about the first axis (OO'), a jack (40) connected by a end to the structure (3), the pivoting actuation means (4) comprising a lever (5) pivoting about a second axis (AA ') off-center with respect to the first axis (OO') and an arm (6 ) pivoting about the same second axis (AA '), the distal end (51) of said lever (5) being connected to the cylinder (40), the proximal ends (50, 60) of the lever (5) and of the arm (6) ) being integral and pivoting along the second axis (AA '), the distal end (61) of the arm (6) comprising pivoting guide means (7) of the first bar (21) during actuation of the jack (40). Figure for the abstract: Fig. 2
