Fred Hardy of Cable Consultants Corp., in the Charlotte, NC, USA office, relates that Sesotec GmbH of Schönberg, Germany, is a global manufacturer of inspection devices and sorting machines for the plastics recycling and plastic pellets industry. Maximized Throughput & Defects Removal Sesotec’s high-capacity Vision Series color sorter precisely detects and ejects defects as small as 0.5 mm with pneumatic air valves. The Vision Series color sorter is designed to maximize throughput and defect removal while decreasing false rejects. The Vision Series’ vision module is comprised of the following three component systems: adjustable RGB LED illumination bar; high-resolution monochromatic or full-color cameras (detect light in the visible spectrum); and NIR or Near InfraRed sensors (detect light reflected well beyond visible spectrum). Shape-sorting and defective pixel count analysis is used to further differentiate between two product types. Air jets separate the material into two streams, which can be automatically resorted, if required. Machine sizes range from one to six 360 mm chutes, each with capacities ranging from hundreds to thousands of pounds. Materials that are suitable for sorting with the Vision Series include virgin pellets, flakes, chips and other plastics that are reduced in size. Noticeable color and shape differences suggest a product is suitable for color sorting. New Software & the Latest Technologies New software for the Vision Series color sorting system features a userfriendly and intuitive touchscreen. Also, the system’s LED lighting system increases the contrast on the finest contaminants and provides a constant light quality. And a special chute design provides the capability to process a higher level of throughput than conventional material sorting machines having the same operating width. The latest-generation air valves further reduce the loss of good material as well as provide a longer service life. Extended Defect Detection & Shape Sorting Capabilities In addition to the Vision color sorter, Sesotec has recently released the Quasar sorter, which harnesses the power of modern computing to further automate the sorting process. The multi-core processor operates 4K cameras that extend the defect detection capabilities as well as expand the shape sorting technology. Sniper Ejector Logic software dynamically fine tunes the air jet shape and intensity based on defect size and speed. Future software improvements can be remotely installed, making the machine virtually future-proof. Additional Ancillary Components Sesotec also manufactures magnets and metal detectors that are utilized in various virgin and recycled plastics production lines.
