Retrofit of the RSM 4 winder

Perlen Papier AG

The RSM 4 from Perlen Papier AG (Switzerland) is a fully automatic winder with a variable carrier roll geometry. With a maximum speed of 3,500 m/min, it was the fastest machine in Europe for many years. In 2014, KRIKO replaced the DOS-based Beloit Beltronic operating system with a modern Siemens WinCC system. In 2020, KRIKO received the order to replace the ALSTOM converters and the Logidyn control system.

 

[Translate to English:] RSM4 Perlen Papier

Requirements for KRIKO:

  • Replacement of the ALSTOM converters and the Logidyn control system
  • Use of a user-friendly and standardized system
  • Drive program written in CFC
     

The KRIKO Solution

Perlen Papier AG opted for ABB and the ACS880 MMA device series. A key factor in the decision was that the ACS880 is at the beginning of its product cycle. Further arguments in favor of ACS880 are the direct torque control (DTC), the clear and compact system design, as well as the ease of maintenance of the inverters. The customer wanted a user-friendly, standardized system.

What does standardized mean? The drive and control program run in a common PCS 7-410H CPU: this eliminates the old hardware interfaces. The CPU is already in use at the customer: this simplifies spare parts management. The control program uses CFC as the programming language, so we have also executed the drive program in CFC.

This benefits the maintenance staff. And the customer has access to the control system, drive control, inverter and operating stations via a virtualized engineering station. Thanks to this standardized system, the remote access set up and our well-trained staff, KRIKO also offers the customer the service and prompt support that such a highly complex and important machine needs from time to time.

The KRIKO Drive Control System 

30 years of experience in drive and automation technology are combined in the KrikoDCS standard library. The modular software modules in the library are used to control multi-motor systems. The modules can be used in the classic S7 controller, the PCS 7 process control system and the new TIA controller from Siemens. The Kriko DCS library has interfaces to power converters and inverters from ABB, Siemens and other manufacturers. In addition, the machines can be operated via TIA panels as well as WinCC and PCS 7 OS stations.

KRIKO DCS References

  • KRIKO DCS is used for small doctor rollers, e.g. for tea bag paper with 14 g/m², up to rolling machines with a width of 10 m, a maximum speed of 3,200 m/min or a reel diameter of 3.5 m and a weight of 50 tons.
  • KRIKO DCS is also used in aluminum rolling mills and in the production and coating of plastic webs.
