Abstract: A description is given of a system for controlling the quality of products in output from a cutting machine, in particular a cutting machine used for cutting logs of sheet material, in particular paper, having at least one cutting disc (11) and a sharpening wheel (14), said control system comprising a PLC controller (20) suitable for controlling the cutting and sharpening process and an inspection system (S) suitable for scanning, at a specific time instant (t(k)), a set of quality values (Qout) of a roll (15) in output from the cutting machine, wherein a processing unit (D) receives said set of quality values (Qout) of the roll (15) in output and sends to the PLC controller (20) a command aimed at performing an action consisting of increasing or decreasing one of the following parameters: - sharpening time (∆tsharp) - sharpening frequency (fsharp) - differential speed (∆v) between said wheel (14) and said disc (11) based on the comparison between said set of quality values (Qout) and a reference quality value (Qsetpoint) and of the action carried out at the previous time instant (t(k-1)).

Abstract: A description is given of a system for controlling the quality of products in output from a cutting machine, in particular a cutting machine used for cutting logs of sheet material, in particular paper, having at least one cutting disc (11) and a sharpening wheel (14), said control system comprising a PLC controller (20) suitable for controlling the cutting and sharpening process and an inspection system (S) suitable for scanning, at a specific time instant (t(k)), a set of quality values (Q out ) of a roll (15) in output from the cutting machine, wherein a processing unit (D) receives said set of quality values (Q out ) of the roll (15) in output and sends to the PLC controller (20) a command aimed at performing an action consisting of increasing or decreasing one of the following parameters:
- sharpening time (Δt sharp )
- sharpening frequency (f sharp )
- differential speed (Δv) between said wheel (14) and said disc (11) based on the comparison between said set of quality values (Q out ) and a reference quality value (Q setpoint ) and of the action carried out at the previous time instant (t(k-1)).
