New Sensor Sorter for Better Results
Plastic foils are among the most important raw materials for recycling and are already reused to a substantial extent. On account of its light weight and high space occupancy, plastic film sorted on a standard sorting machine is hindered by restrictions and reduced conveyor speeds.
To meet the today’s demands, sorting systems have to be efficient. Specifications are becoming more and more stringent and users of processing and sorting plants are constantly required to respond to improved recycling rates whilst being called on to reduce the overall volume of waste following processing. Sensor technology potential in the recycling sector – or to be more precise, detection of the wide variety of different plastic materials emanating from different material-flow sources – have remained largely untapped.

The UniSort Film sensor sorter is the newest machine from German Steinert Group for this sector and has been designed specifically for improving the sorting potential. The machine is equipped with the state-of-the-art Active Object Control-System (AOC), engineered by RTT Steinert and originally developed for fine-product sorting on the UniSort Flake range for larger particle sizes. As in the case of small objects, the sorting of buoyant flat objects is governed by the motion behavior of the material being sorted in terms of material detection and ejection – having a substantial impact on purity and efficiency. “AOC is a stabilisation system catering for defined motion paths controlling the material sorted, hence delivering a distinct improvement in quality of the final product,” Steinert explains. “Stable motion of the objects even at double conveying speed results in higher throughput rates while enhancing the efficiency of the system.” According to the company, the system is universally suitable for all functions involving the sorting of air worthy objects, e.g. paper and film, including agricultural film.
In addition to this, the UniSort Film system is equipped with modern HSI (Hyper Spectral Imaging) camera technology, ensuring a high degree of flexibility and future sustainability.
