TIP ROL-0404 Ultra-Sonic Tension Control for “SU” Rollstands
Machine Model for ImprovementFolio-size sheeter type SHM 1400
Description of Improvement
This upgrade is part of the Technical Improvement Program (TIP); it adds ultrasonic tension control to the SU roll stands. This conversion consists of adding a 30 mm proximity switch with a sensing range of 120 mm to 2000 mm.
The proximity switch is mounted to detect the distance from the roll to the switch. This distance is then converted to 0-10V DC analog output. As the roll diameter gets smaller, analog voltage increase. This information is then evaluated and the result is passed onto a newly supplied proportional air valve, which in turn adjusts the brake pressure. Coalescing filter ensures air quality to the proportional valve is clean.
- Improved tension control
- Improved and consistent machine performance
- Easy setup and calibration
