Purpose and goal
The preliminary study should investigate whether an operator support can be developed for the paper industry, which can detect deviations in rolling Paperrolls early in the process. The solution was based on optical measurement technology and an interface for the process operator. The potential is great as most of the paper mill have some type of rolling machine. Optical sensors are available in different variants adapted for industrial environments. However, the most significant challenges are to handle dust and vibration during measurement, which may prove problematic
Expected results and effects
All rolling machines looked different, which complicates measurement. They are all of different makes and age, but have a common basic design.The project identified several possible locations for sensors. The majority of positions are located under the rolling machine with sensors directed upward between the two drums. A combination of different placements is required to measure all parameters.The project ensured that the differences between installations were taken into account, thus increasing the chance that a future solution could be implemented in many paper mills.
Planned approach and implementation
A review of the main construction and function of the roller machine was studied and a compilation of the requirements. It was then created a conceptual formulation that was discussed at frequent visits to all paper mills where high-speed filming was also conducted to study the environment and measurement objects during rewinding. With improved conceptual solutions, 2 Paper mills were visited for verification and anchorage for the problem owners. Finally, an estimate of hardware costs for the concepts was made. And a proposal for operator interface was presented.
