Objective
The parallelism of rolls is a key point for the productivity of processing lines for paper, aluminium, plastic, steel, etc. in the form of a web. That's why a regular control of roll parallelism is scheduled. But, till now this operation is time consuming, tedious and expensive. Research work is proposed to develop a completely new tool for the control of roll parallelism based on optical gyroscopes that are recently accessible for industrial applications. The proposed system should comply with following specifications: - high angular accuracy (about 10 4 radians) - compatible with difficult access and harsh environmental conditions - very fast operation; 5 minutes instead of 1 hour for the parallelism alignment/roll - easy to use: battery powered mobile sensor, small size (20 x 20 x 20 cm3) and light (4 kg) The project will begin with the concept study of two units: - an optical gyroscope based reference unit , aimed to transport a stored reference direction (first roll axis, direction perpendicular to the line axis). It is intended to take advantage of the specific requirements differences of this application regarding the aeronautic sector in order to accurately check the parallelism by means of only one high precision laser gyroscope instead of a triad. - an innovative optical alignment unit integrated in the mobile gyroscopic unit that is able to acquire the reference direction and to measure the misalignment between the roll axis and the reference unit. It is intended to reach an angular coverage of 2ø at 2 m even with small optics by means of an original optical configuration helped by a specific data processing. In parallel, a marketing study will be started to prove the economical viability and a theoretical approach will be carried out to determine a parallelism criterion versus mechanical properties of existing products and products to be processed in the mid term future. After the design period in which all the results obtained in the preceding tasks are used, the two units will be developed. Finally, comparative tests will be carried out in industrial processing lines in order to define measurement procedures. The control system concept can be applied in many industrial sectors that use rolls to guide a web. It is expected that many SME active in the surveying or the construction of industrial machinery will profit from the research results of this project. Because of the present trend in different industrial sectors to process thinner and wider high quality products, what is only possible by a better and more regular control of the processing line condition, the increasing demand for SME sub contractors using better alignment tools will boost the commercial exploitation of this project. Indeed, the benefits for companies processing continuous webs are important too: reduction of down times, product down gradings or strip breakage risk, possibility to process a wider product range, processing speed increasing, higher productivity. The research fits Area 1.1.4.S 1.4.1.S and 2.3.2.S of the Industrial and Materials Technologies programme.
