Inline inspection and sorting on a new level

During the online quality control of plastic pellets, SIKORA’s PURITY SCANNER ADVANCED ensures that only pure material enters the further production process. Even smallest, critical contamination are reliably detected and automatically sorted out. Both the detection and the ejection behavior of contaminated pellets are perfectly coordinated.

3 cameras for an even higher detection rate
Thanks to the modular system design of the PURITY SCANNER ADVANCED, different camera types can be used depending on the material being inspected. In addition to optical cameras, which detect black specks and discolorations, an X-ray camera can be installed to detect metallic contamination. Common systems on the market have a maximum of 2 optical cameras. However, these quickly reach their limits due to a relatively low coverage as soon as the contamination are outside the field of view of the installed cameras. Therefore, SIKORA offers its customers the possibility to have a third optical camera installed, if required. This camera setting offers a significantly higher detection rate, so that more contamination are detected. This is especially advantageous when the PURITY SCANNER ADVANCED is integrated directly into the production line as an inline system and multiple sorting with a typical 2-camera system is not possible.

Reducing bycatch intelligently
The PURITY SCANNER ADVANCED automatically sorts out the detected contamination via a blow-out unit. According to the higher detection rate, more detected contaminants are detected and sorted out with a 3-camera setting. Against this background, the optimization of the by-catch becomes more important. Therefore, SIKORA has developed the feature of “hybrid blow-out”. The customer can define in advance which impurities in the material represent uncritical contaminations and select a smaller blow-out unit for these, so that their by-catch is reduced. These include, for example, small, light-colored black specks that frequently occur in the material. On the other hand, a larger blow-out unit is specified for critical contaminants – for example, metal contaminants that can impair the functionality of the subsequent end product.

An investment that pays off every day
Thanks to the intelligent interaction of the highest possible detection and hybrid blow-out, the PURITY SCANNER ADVANCED guarantees safe material of the highest quality. This further optimizes production processes and the reduced by-catch contributes to cost-efficient and sustainable production.

The PURITY SCANNER ADVANCED can be equipped with two or three optical cameras as required
