German-based floorboard plant, Classen Industries, produces 60 000 to 70 000 square metres of floorboards every day at its floorboard plant located in Baruth, Germany. The facility produces 20 more floorboards per minute than any other plant, which translates into 28 800 more boards daily. Classen gives credit to the company’s drive partners and automation specialists for their success.

The entire packaging line in the floorboard plant is controlled using Movi-PLC motion and logic controllers provided by the automation specialists. There are three Movi-PLC advanced DHF41B controllers and 25 servo drives that are controlled by Moviaxis multi-axis servo inverters. The palletising section uses a further five servo drives and a Movi-PLC advanced DHF41B controller.

The automation specialists have provided a complete axis system comprises a master module with a Movi-PLC advanced integrated motion and logic controller, a power supply module and a varying number of axis modules. These Moviaxis axis modules are powered via a shared power supply module. Regenerative power from an axis is relayed directly to the motor-run axes.
The double-end profiler sets the production cycle on Line 7. It uses a multi-turn encoder to provide a target value for the pulsing of the entire packaging line. The master value is loaded by the first motion controller and is converted to the corresponding production cycle. The resultant virtual master is then relayed via the CAN-based SBus system bus to all other connected Movi-PLCs. Based on MultiMotion software and using cams, every motion controller calculates specific travel profiles that are synchronously transmitted via the SBus to the relevant axes.
Consequently, every drive – supplied by the drive partners -in the axis system works synchronously and the speed automatically adapts to the lead speed. As a result, the floorboards can be processed to high standards even in large volumes.
