              • KUSTAx.xMSI - NIR hyperspectral imaging cameras for recycling

              • High-speed identification and analytical imaging in sorting processes
                The hyperspectral cameras KUSTA1.7MSI, KUSTA1.9MSI and KUSTA2.2MSIsens (KUSTAx.xMSI) are designed for the identification and the subsequent sorting of materials from waste collections (recycling).

                KUSTA1.7MSI and KUSTA2.2MSIsens are particularly suitable for the identification of fine grained materials (flakes, agglomerates, granulates) of a few mm in diameter on fast moving conveyor belts. Whether the hyperspectral camera KUSTA1.7MSI or KUSTA2.2MSIsens is proposed depends on the NIR absorption characteristics of the material to be analysed.

                The high sensitivity of the hyperspectral camera KUSTA1.9MSI permits applications like:
                • PVC elimination of PET-flakes
                • Identification of thin foils in mixed plastics

              • uniSPECx.xFOM - Fiberoptic NIR hyperspectral cameras

              • Multi point measurement for analytical quality control
                The NIR hyperspectral cameras uniSPEC1.7FOM, uniSPEC1.9FOM and uniSPEC2.2FOM (uniSPECx.xFOM) combine LLA Instruments’ NIR hyperspectral imaging technology (e.g. uniSPECx.xHSI) and fibre optics instead of an objective as optical element.

                The fibre optical hyperspectral camera is advantageous in case small installation heights are requested for large conveyor belt widths. The flexibility of the fibre cables enables e.g. online quality control of finished products on various conveyor belts which may even be many meters apart from each other. Generally, uniSPECx.xFOM and uniSPECx.xHSI are suitable for the same application fields.

                The uniSPECx.xFOM can be equipped with up to 64 optical fibre cables. The optical fibre cables consist of low-OH quartz material, enabling a high speed transmission of NIR radiation to the spectrometer. The high frame rates of the uniSPECx.xFOM (270 Hz for uniSPEC1.7FOM and uniSPEC2.2FOM; 795 Hz for uniSPEC1.9FOM) ensure a better performance at high conveyor belt speeds compared to the multiplexed NIR spectrometer uniSPECx.xMPL-24V.

                The uniSPECx.xFOM is integrated into a control cabinet including optical fibre cables, splice box and an industrial PC for camera control. The industrial PC includes camera control software and pre-configured application software, depending on analysis (sorting) task. The control cabinet has a degree of protection level of IP54 (camera itself IP 65).

              • Multiplexed NIR spectrometer technology

              • NIR identification in sorting processes
                Multiplexed NIR spectrometer are widly used for the identification of plastic material in recycling plants. Waste collections from e.g. household waste are identified and analysed by an optical spectrometer and can therefore be sorted out.
                  • KUSTA1.9MPL-24V - Multiplexed NIR spectrometer for recycling

                  • Material identification in sorting plants
                    Multiplexed NIR spectrometer KUSTA1.9MPL-24V (formerly KUSTA1.9MPL) is a fast scanning near-infrared sensor, which is used for the identification of bulk solids in sorting plants. On a conveyor belt the singulated material is passed by under the illumination unit and the reflected radiation is transferred to the optical multiplexer via fiber cables. The multiplexed spectrometer scans the 64 measuring tracks at frequencies of up to 70 Hz and sends the identification results to the process control via an ethernet protocol.

                    KUSTA1.9MPL-24V is mainly used in plastic- and waste paper recycling. Depending on the application certain standard identification routines are included, which enable to reject several material types referring to freely selectable criteria.

                    In the version “-24V”, which is available from January 2016, the optical multiplexer, the spectrometer and the RGB sensor come in a separate housing of protection degree IP65, which can be mounted directly at the probe. Due to the high scan rate, materials on even 2 to 3 m wide conveyor belts can be identified at speeds of up to 3 m/s. For the detection of smaller particles (< 30 mm in diameter) hyperspectral imaging cameras KUSTAx.xMSI are recommended.
                  • uniSPEC1.9MPL-24V - Multiplexed NIR spectrometer for science

                  • NIR technology for quality control
                    Multiplexed NIR spectrometer uniSPEC1.9MPL-24V (former uniSPEC1.9MPL) was developed for analytical evaluation of material in the production process. Due to the high spectral resolution, these NIR spectrometers are ideal tools for scientific applications. Additionally, a high luminous intensity and a large sensitivity of the spectrometers are perfect properties for the use in quantitative- and rapid analysis applications of material streams.

                    The spectrometer are widely used as online analytics in food industries, plastics- and paper industry, for thickness measurement in control of coatings, the quality control in mineral industry and many more. Depending on the application, uniSPEC1.9MPL-24V is utilised. LLA advises the best fitting device for the customised application.

                    For each application, customised analysis modules are developed. Additional control software for the NIR spectrometer is custom-built and scope of delivery. The user interface can be designed and customised. The software can be used to store measured information for a future analysis or to change parameters in working processes.

                    The multiplexed NIR spectrometer can be connected to probe lines (64 measurement tracks) via fiber cables. Thereby a spatially resolved recording of material streams is generated.

                    In real time, analytical results will be automatically forwarded to a subsequent control system (e.g. nozzle control system) by a standardised interface (e.g. Profibus, Ethernet). This ensures a reliable identification and ejection of defective material (impurities, rejects, extraneous material).

                    • Minimised noise level
                    • High image contrast
                    • Low power consumption
                    Synchronisation problems, which cause blooming effects or image artefacts in common trilinear sensors, do not occur due to the usage of CMOS technology.

                    The high effective resolution of 2048 tracks combined with a digital resolution of 12 bit and a full frame rate of 260 Hz to 850 Hz provide an outstanding performance of uniScanRGB. Even smallest objects are scanned in detail at high frame rates, enabling the usage of uniScanRGB in sorting and screening applications requiring both: high resolution and high speed. The RGB line scan camera is equipped with an industrial proof RGB objective lens and integrated into an IP 65 rated housing, enabling maintenance-free 24h/7d operation. Several binning modes for the combination of the RGB line scan camera with hyperspectral cameras KUSTAx.xMSI or uniSPECx.xHSI are available. The dynamic range is then increased to 16 bit, enabling a better performance at unfavourable lighting conditions.

                    Included in delivery is a preconfigured industrial PC with camera control and analysis software. The analysis software can be customised for specific tasks including sorting and monitoring applications. Prior to data evaluation, the software transfers the RGB data automatically into the user-friendly HSV-colour model. The analysis result is sent to an external process control unit (e.g. SPS control) via standard Gigabit Ethernet interface in real-time. In addition to the type code, the HSV information is available as well.

                    Possible Applications:

                    • Surface inspection of natural materials,
                    • Monitoring,
                    • Scanning
                    Equipment for process RGB - setup

                    • Illumination unit PMAmsi,
                    • Installation bridge,
                    • Automatic calibration unit CUa  
                    • On-line XRF Analyser Line

                    • The on-line XRF analyser line XRFline is suitable for detection of all elements with an atomic number higher than Potassium (in special cases maybe even below). The system uses state-of-the-art X-Ray detector technology. The performance of the KETEK Silicon Drift Detector (SDD) is characterised by:

                      • High count rate capability (>1 Mcps)
                      • Excellent peak-to-background ratio
                      • Good energy resolution (~130 eV)
                      • Wide energy range (0.2 keV to 30 keV)

                      Paired with water cooled high power X-Ray tubes the full potential of the SDD´s can be exploited. Therefore the sensitivity of the system is high enough to distinguish between different alloys of stainless steel, bronze, brass and more.
                      The resolution across the belt can be selected basically free (the smallest possible width is 25 mm) and will be adjusted for each system according to the size of the analysed material stream. The resolution along the conveyor belt depends strongly on the belt velocity. The minimum resolution is about 1/100 of the belt velocity (e.g. 25 mm at 2.5 m/s). Hence it results for high throughput a smallest pixel size of about 25 mm x 25 mm. Bigger objects will be detected in several pixel and identified as one object, while smaller objects are detected as single objects as long as they are sufficiently separated.

                      By reducing the belt velocity and increasing the acquisition time per pixel a higher elemental sensitivity can be achieved to detect elements in low concentrations or small amounts (alloys, REE, PGM,…)
                      The housing of the XRFline fulfils the radiation safety requirements according to the Radiation Protection Ordinance of Germany. The radiation protection at and around the conveyor belt has to be provided by the manufacturer according to the effective Radiation Protection Ordinance at the place of operation. Furthermore the XRF line camera is integrated into a IP 65 rated housing, enabling maintenance-free 24h/7d operation.

                      Included in delivery is a preconfigured industrial PC with sensor control and analysis software. Due to the huge material variety the analysis software has to be customized for specific applications. The analysis result is sent to an external process control unit (e.g. SPS control) via standard Gigabit Ethernet interface in real-time.

                                  Development and modification of analysis models require the handling and visualization of large data sets. For this purpose, KustaSpec permits simultaneous loading, grouping and colouring of thousands of NIR-spectra.

                                  A comprehensive range of mathematical operations e.g. derivations are available for spectral processing. Statistical data evaluation as well as graphical analysis tools e.g. scores plot and vector plots are implemented for the validation of new applications by NIR test sets. The NIR test sets and learnsets (NIR reference spectral dataset for application development) can be generated and modified by KustaSpec as well.
