TIP C 4040 Replacement of obsolete Microbox IPCs with Siemens S7 TIA / Sinamics

TIP C 4040 Replacement of obsolete Microbox IPCs

Machine Model for Improvement

All Bielomatik cut-size sheeters equipped with Siemens Microbox IPCs

Description of Improvement

This upgrade is part of our Technical Improvement Program (TIP) and replaces the existing obsolete Siemens

Microbox IPCs controlling the drive automation functions.

The existing Siemens Microbox computers controlling the drive and automation functions are obsolete and will be replaced by the new Siemens PLC S7 TIA Portal controls and Sinamics drive system.

All previous functions will be transferred into the new Siemens S7 TIA Portal PLC, e.g. counting, splice detection, rejection, cut-off length measurement, web tension and overlapping gap position control. The specification of the cross cutter drive and the speed curve will be equal or better as before the upgrade.

A sheeter that we had planned especially for our lightweight specialty papers has become an all-round smart sheeter that can process even heavy grammages up to 300 gsm with maximum cutting accuracy.
