Abstract
A cutting device having cutting means for cutting a cigarette rod transversely along a cutting plane; a carriage for accompanying the rod through the cutting plane; an operating unit for moving the carriage back and forth in a travelling direction crosswise to the cutting plane; and a control unit, in turn having two proximity sensors, and which determines at least one fault on the operating unit as a function of recording signals emitted by the sensors.
Claims14
A cutting device for cutting at least one rod of material in the tobacco industry into substantially cylindrical portions, the cutting device (3) comprising cutting means (5) for cutting the rod transversely along a given cutting plane (9);
- a carriage (10) for accompanying the rod and the portions through the cutting plane (9);
- and an operating unit (11) for moving the carriage (10) back and forth in a travelling direction (A) crosswise to the cutting plane (9);
- the carriage (10) comprises at least one channel (12) for supporting the rod and the portions at the cutting plane (9), and through which the rod and the portions are fed in use;
- and the cutting device (3) being characterized by comprising a control unit (20), in turn comprising at least one proximity sensor (21, 22) for emitting at least one recording signal relative to the position of the carriage (10) with respect to at least one reference position, and a computer (23) which compares the recording signal with at least one reference data item to obtain at least one comparison data item and determine at least one fault of the operating unit (11) as a function of the comparison data item.
