Smart Sorting

Many industrial production processes involve sorting tasks. Be it the separation of good from the bad product, the removal of unwanted contaminants or the enhancement of product quality. Most of these tasks require sensor-based technologies.

EVK´s NIR Hyperspectral Imaging Systems can accurately detect different materials according to their chemical composition. This feature allows the EVK systems to operate in fields where colour cameras reach their limits.

Moreover, the combination of a Colour- and Hyperspectral Imaging camera vie Sensor Fusion is an often used solution to increase sorting sensitivity and specificity.

This allows separating materials by means of their colour, shape, size and in addition to their chemical composition.

Hyperspectral image processing in sorting

EVK HELIOS, the smart hyperspectral imaging analysis and sorting system, is available in the wavelength range NIR (0.9-1.7μm) and has been specially developed for industrial use in harsh environments: none moving parts, therefore with low maintenance requirements, also due to the robust design.

Smart metal scanner

EVK ABAS TL is an inductive metal scanner for use in sensor-based sorting machines for detection and sorting of metals. 

EVK Professional Services support you during the Pre-sale phase, at Integration and in the After-sale phase.

Smart solutions are based on Hyperspectral, Colour and Conductivity imaging, and when coupled to EVK Sorting Engine Module, enable a multilevel system integration – from sensor head to material ejector block.

EVK Sorting Engine Modules offer flexibility in sensor choice and adaptability for creating complete solutions, for many different types of applications. EVK combines its hardware with software, to create classification and sorting algorithms that combine all EVK sensor technology and control material ejection in real-time.

In this manner, conveyor belts can be efficiently transformed into sorting machines. Hardware situated in the camera housing is where data is processed, steering decisions are made and then sent further on to ejection units.

To speed up integration into a sorting machine, EVK offers lighting and IO card solutions via EVK Professional Services.

EVK Professional Services on-site assistance and integration is also available.

Combination of Hyperspectral Imaging and Inductive Sensors

In many industrial applications, a high performance can be achieved by combining various sensor technologies. EVK technology supports the integration of various sensor types into sorting decision algorithms. For instance, combinations of Hyperspectral cameras with arrays of induction sensors are widely used in recycling to sort valuable metals and different types of plastic (based on material type and not colour), from the recycling stream.

Combination of Hyperspectral Imaging and Colour camera systems

The combination of colour and hyperspectral cameras enables more precise sorting based on material type and colour. The sorting output can, therefore, be refined to pure fractions composed of a unique product, such as Red PE plastic flakes. This adds value to the recycled product since it can be optimised to suit down-stream production processes. Please contact us for further information.
