In 2016 Axis Controls were commissioned by Chase Corporation in Rye Hastings to completely replace the drive control system and operator control desk on one of their Titan SR5 machines.
The existing DC drives were retained, and we designed our winding control system around the Parker 590 DC drive range. We replaced the tacho feedback on the motors with encoder feedback to give a greater level of speed control.
As a Siemens systems integrator, we opted for the ET200SP control platform along with a Siemens 12" comfort HMI for the operator control interface.
Machine safety was designed around the Sick Flexisoft system. All safety devices including E-stops, gate switches, guard switches and pull wire switches were easily integrated.
Sick ultrasonic sensors were fitted to the top and bottom rewind shafts, to aid the rewind diameter calculations.
SMC electronic pressure regulators ( E2P ) were fitted to the top and bottom rewind differential air shafts. Manual or automatic tension control could then be achieved via the touchscreen interface.
Finally, we installed an SMC anti-static ionization bar above the rewind web path. As the rewind material was a thick industrial plastic film, this eliminated the commonly found static build up.
