Voith expands Papermaking 4.0 portfolio with three new apps for higher process stability and efficiency in paper production.

Customers worldwide rely on Voith’s modular Papermaking 4.0 portfolio to individually optimize their production with the leading digital industrial applications. Based on extensive expertise, Voith is introducing OnEfficiency.BreakProtect, OnView.VirtualSensorBuilder and OnView.MassBalance, three new apps on the IIoT platform OnCumulus. The new digitalization solutions feature the highest safety standards, are quick to install and easy to use. The technologies are already successfully implemented in several plants worldwide. Due to the process optimizations and lower resource consumption, the applications often pay off in less than a year and pave the way to the digital paper mill.

OnEfficiency.BreakProtect — Detect, understand and prevent paper break causes

The IIoT platform OnCumulus has already established itself as a central hub for data from multiple sources for numerous paper manufacturers. OnEfficiency.BreakProtect uses artificial intelligence to analyze the process data bundled in OnCumulus. Thereby, the innovative solution automatically detects various critical process conditions that can lead to breaks. This allows the development of specific countermeasures and the reliable prevention of tear-offs.

“I am always fascinated by the correlations that artificial intelligence can recognize,” says Jürgen Käser, director process applications at Voith. “Among other things, we were able to use OnEfficiency.BreakProtect to identify increased dirt and starch agglomerate loads – for which there is no measurement data at all – at the SpeedSizer pulper. In the past, these had repeatedly led to break-off series. A small mechanical rebuild, which prevents starch from entering the pulper in larger quantities, has permanently solved the previously undetected problem.”

OnView.VirtualSensorBuilder — Calculate and visualize quality parameters quickly and easily using virtual sensors

Virtual sensors, also called soft sensors, have proven themselves in the process industry for many years. With the help of data models, the sensors calculate various quality parameters and thus reliably supplement laboratory tests. Until now, the use of virtual sensors required considerable time and, above all, data analysis skills. With OnView.VirtualSensorBuilder, Voith introduces a user-friendly app that allows paper manufacturers to quickly and easily create the virtual sensors themselves with just a few mouse clicks.

“With OnView.VirtualSensorBuilder, it only takes a few hours for a new soft sensor to be ready for use,” says Maria Knauer, global product manager efficiency solutions at Voith. “Previously, this required a time-consuming and costly process of several weeks.”

Once installed, operators can use OnView.VirtualSensorBuilder to continuously calculate, visualize and control relevant quality values, such as strong values, in real-time. Combined with OnCumulus.Suite, the digital application identifies critical values and provides preventive warnings, allowing personnel to make immediate improvement adjustments. The solution thus increases process stability, enables compliance with desired quality standards, reduces raw material costs and minimizes waste.

OnView.MassBalance — Visualize and reduce fibre losses in stock preparation

OnView.MassBalance maps the current stock flows in an intuitive Sankey diagram and provides information on deviations that are no longer within the standard range. If a defined warning threshold is exceeded, the application automatically highlights the relevant area in the diagram and recommends suitable action to avoid fibre losses. OnView.MassBalance thus leads to targeted process optimization in stock preparation and also enables centralized knowledge management.

With the help of OnView.DigitalEye, the accuracy of OnView.MassBalance can be increased even further. The innovation makes it possible for the first time to analyze recovered paper quality even before stock preparation with the help of artificial intelligence. The award-winning AI application OnView.DigitalEye is currently undergoing final testing as part of pilot installations at national and international customer sites and is expected to be available starting next year. Another application that will be launched in 2022 is OnView.Energy from Voith. The app visualizes and analyzes energy consumption and CO2 emissions in production. This enables significant savings potential to be identified, leading to lower energy costs, improved sustainability and competitiveness.

2023 promises an interesting ride for print in India

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. While the print and packaging industries have been resilient in the past 33 months since the pandemic lockdown of 25 March 2020, the commercial printing and newspaper industries have yet to recover their pre-Covid trajectory.

The fragmented commercial printing industry faces substantial challenges as does the newspaper industry. While digital short-run printing and the signage industry seem to be recovering a bit faster, ultimately their growth will also be moderated by the progress of the overall economy. On the other hand book printing exports are doing well but they too face several supply-chain and logistics challenges.

The price of publication papers including newsprint has been high in the past year while availability is diminished by several mills shutting down their publication paper and newsprint machines in the past four years. Indian paper mills are also exporting many types of paper and have raised prices for Indian printers. To some extent, this has helped in the recovery of the digital printing industry with its on-demand short-run and low-wastage paradigm.

Ultimately digital print and other digital channels will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future. For instance, there is no alternative to a rise in textbook consumption but this segment will only reach normality in the next financial year beginning on 1 April 2023.

Thus while the new normal is a moving target and many commercial printers look to diversification, we believe that our target audiences may shift and change. Like them, we will also have to adapt with agility to keep up with their business and technical information needs.

Our 2023 media kit is ready, and it is the right time to take stock and reconnect with your potential markets and customers. Print is the glue for the growth of liberal education, new industry, and an emerging economy. We seek your participation in what promises to be an interesting ride.
