<p>A labelling machine with a carrousel (3) comprises one or more labelling devices (9) which can be removably associated with the periphery of the carrousel (3) and which can be positioned in a plurality of different angular positions along the periphery of the carrousel (3), and at least one central control unit (12) operatively associated at least with the carrousel (3) and with the labelling device (9) for controlling their operation. The machine (1 ) also comprises at least one protective structure (5) mounted on the main supporting frame (2) and in turn comprising a plurality of protective elements (17) arranged around the carrousel (3), each being able to move between a first position in which it prevents access to the carrousel (3) and a second position in which it allows access to the carrousel. There are also first detector means (13) for detecting the presence of the one or more labelling devices (9), and second detector means (28), for indicating to the control unit (12) at least which protective elements (17) are, or could be, in the second position. The central control unit (12) is also programmed to prevent the labelling machine (1 ) from operating when the second detector means (28) detect at least one protective element (17) which is or could be in its second position, where no labelling device is detected.</p> |
