Poka Yoke FIAM Utensili Pneumatici Spa

These screwdrivers/nutrunners with TOM - PM computerized monitoring unit are practical and simple monitoring systems poka-yoke type (anti-error system) counting good and no-good screws thanks to the "screws counting" function. In case of high production rate you won't risk any missing screw.
TOM-PM (Tightening Operation Monitor - Pressure Monitoring): poka-yoke system that allows the monitoring of the tightening cycle through the double-signal pressure coming from the screwdrivers, subsequently converted into electric signal * 1 sequence of tightening through internal PLC with maximum 999 screws for sequence and programming the maximum number of tightening attempts for KO screws * Automatic check of tightening time which can be adjusted (by
setting the cycle time) thus discriminating the different KO results * Visual indicators of the tightening status positioned on the front panel of the unit * Different acoustic signal * Reset cycle or releasing pallet/jig * Electric signal for "end cycle OK" to release pallet/jig (or manual with key selector) * Last tightening annullated: decrease on counter in case of untightening * I/O connectors for connection to PLC and/or to light signal systems
