Ribbon saw with double security system

A ribbon saw with double security system coupled to a machine (1) and comprising a cutting ribbon (3), vertically coupled to an upper pulley (12a) within an upper housing (1a) having an upper recess (2a) and a lower pully (12b) within a lower housing (1b) having a lower recess (2b), with an electric motor (13) within the lower recess (2b) connected to an electronic control, the electric motor (13) linked to a driving wheel (17) through a transmission (18) and a lower braking system connected to the electronic control having a pneumatic clamp (15) that acts on a brake disc (14) located intercalated on a common shaft (16) between the driving wheel (17) mechanically coupled to the lower pulley (12b), an artificial vision security system that comprises, at least, a camera (5) installed on the upper housing (1a) and oriented towards a table (4) which is defined at the top of the lower housing (1b) so that it captures an image of an area including the cutting ribbon (3), the camera (5) being connected to the electronic control to trigger the lower braking system and stop the cutting ribbon (3) when the camera (5) detects a predetermined color of gloves worn by an operator of the machine (1), and comprising a magnetic security system that, in turn, comprises, at least, a detector (6) installed on the table (4), just in front of the cutting ribbon (3), said detector being connected to the electronic control in order that at least the lower braking system is automatically triggered and stops the cutting ribbon (3) when the detector (6) remotely detects without contact, the presence of metal detectable blue gloves worn by the operator of the machine (1) and characterized in that the lower braking system of the double security system is triggered by what is detected by the camera (5) of the artificial vision security system and is also triggered by the detector (6) of the magnetic security system.
