Dispositivo per l'applicazione di etichette per macchine utensili

Described is a device for applying labels (3) on panels or other workpieces configured for being mounted in an operating head (2) of a machine tool (1), equipped with a rotatable gripping element. The device for applying labels (3) comprises: a movable body (6') comprising coupling means (6) for the coupling, in use, to said rotatable gripping element and a rotor (5); a main body (4) in which is formed a cavity in which is housed said rotor (5), said cavity being in communication with at least one expelling member (14a, 14b, 14c) for expelling air and, through a first passage (9), with an opening (11) open towards the exterior of said main body (4); and a first pressure reducing element (16) connected to said main body (4) and in communication with said first passage (9) at a zone between said rotor (5) and said opening (11). Moreover, said rotor (5) is configured in such a way that, when it is rotated, it draws air from said first passage (9), allowing the picking up and retaining of a label at said opening (11), and expels air from said at least one expelling member (14a, 14b, 14c) allowing, in use, the cleaning of a panel or another piece which is to receive said label.
