Abstract

Dispositif pour actionner des vis, particulièrement dans des presses d'impression, au moyen d'un outil de vissage qui peut erre réglé pour un sens déterminé de rotation, et pour un couple de vissage déterminé. Selon l'invention, ce dispositif est caractérisé en ce qu'il comporte une roue génératrice d'impulsions montée rotative sur l'outil de vissage grâce à laquelle peuvent être engendrées au moins deux impulsions différentes A et B correspondant à des positions angulaires différentes de la roue génératrice d'impulsions, des circuits de temps grâce auxquels peuvent être engendrés un signal C, limité dans le temps, en concordance avec un flanc d'impulsion A et un signal additionnel D, limité dans le temps, en concordance avec un flanc de l'impulsion B et un circuit de type ET, grâce auquel peut être engendré, dans le cas de coïncidence du signal C et du signal D, un signal E, grâce auquel on peut commander un élément de commutation arrêtant l'outil de vissage. de vis. Vissage et dévissage de vis.Device for actuating screws, particularly in printing presses, by means of a screwing tool which can be adjusted for a determined direction of rotation, and for a determined screwing torque. According to the invention, this device is characterized in that it comprises a pulse generator wheel rotatably mounted on the screwing tool thanks to which can be generated at least two different pulses A and B corresponding to different angular positions of the pulse generator wheel, time circuits by which a time-limited signal C can be generated in accordance with a pulse edge A and an additional signal D, time-limited in accordance with an edge of the pulse B and an AND-type circuit, thanks to which can be generated, in the case of coincidence of the signal C and the signal D, a signal E, by means of which a switching element can be controlled to stop the screwing tool . quote. Screwing and unscrewing screws.
