Right: Pellenc ST has developed the Compact+ sorting units for retrofit or refurbishment projects
RGB cameras and metal detectors in a Sensor Fusion system, according to the company. The light source is generally a high multispectral LED light but in special cases, such as PUR foam sorting, the detection unit can involve halogen lighting. Redwave also unveiled Redwave Mate, its AI-support technology for monitoring and optimis- ing the entire sorting system as well as plant operations. Redwave Mate can use data collected by an Industry 4.0 system that communicates information from equipment and machinery in a production cell or plant. Redwave Mate measures, records, and evaluates information collected during production, with the data used as a source for machine monitoring and to ensure optimum system and sorting operation. Pellenc ST has developed new optical sorters specifically designed for installations where space and access are limited. The Compact+ sorters are ideal for retrofit or refurbishment projects and can be built with the option of offsetting the control cabinet or conducting a modular assembly on-site. Compact+ is equipped with company innova-
tions that improve the performance of the unit. This includes use of the new Flow detection system which combines a new spectrometer with an extended NIR/VIS spectrum and focused illumina- tion that enables recovery of waste to high levels of purity. The Flow detection system in example improves the separation of different grades of PET, Pellenc ST said. Other features of the unit include a large display screen on the control cabinet to improve the human-machine interface. Compact+ interfaces with all types of high- speed conveyors supplied by different integrators and is compatible with belt speeds up to 4.5 m/ sec. Its Central Nervous System (CNS) software platform allows operators to integrate technologies such as the Industrial Internet of Things (IioT), watermarking and AI, and other Pellenc ST scan- ners in the form of upgrades. Compact+ features options familiar from Pellenc ST’s Mistral+ Connect line of multi-material sorting

machines for sorting and recycling centres, such as dual vision, metal detection and profile detection for the detection of black and inert materials, the company said. Maintenance and low energy consumption were focused on during the unit’s development. The replacement rate for parts has been considerably reduced and maintenance costs have been minimised. Pivoting reflectors are provided to facilitate the ease and safety of maintenance operations. For energy savings, the unit is designed so that air consumption has been cut by 30% compared to previous ranges of machines, the company said. Users can also use the Smart&Share perfor- mance support application that continuously analyses the operation of the optical sorter from real-time data to help optimise the operation. Users can receive intelligent alerts and customised reports for increased availability and better sorting quality, Pellenc ST said.
Flakes and pellets Anhui Zhongke Optic-electronic Color Sorter Machinery, a Hefei, China-based optical sorter technology company for food in China also offers several machines under its AMD Sortex line for plastics sorting. The company, which had an exhibitor booth at
this year’s NPE Show in Orlando, Florida, US, developed the AMD U series sorting machine for ageing PET flakes and fluorescent flakes. The unit uses a customised high-precision optical system consisting of an advanced, concentrated, ultravio- let light source and a unique image enhancement algorithm to accurately identify extremely faint flaws in the polymer.
