Four non-contact, ultrasonic sensors-two below the frost line and two above it-are part of a new, patented "early warning" IBC control from Addex Inc., Stoughton, Mass. Called Digital IBC, it has a fifth sensor that looks at a fixed target and calibrates the other four. Instead of adjusting the volume of IBC air based on width data collected on the bubble and on the layflat, this gathers data on bubble size changes much closer to the die. Air input to the IBC is then corrected by changing the speed of the AC inverter motors on the intake and exhaust blowers, or with the addition of a new high-speed, servocontrolled air valve, also patented by Addex. The new valve greatly decreases response time for air adjustment on smaller bubbles and critical widths, Addex says. Prototypes have been installed at processors for three years. Twelve commercial systems have been delivered for dies from 1.8 m with a 9-m layflat down to 4 in. with 6.3-in. layflat. Tel: (781) 344-5800 . www.addexinc.com
