Pellet Scanning System PS25C

Manufactured By: Optical Control Systems GmbH

Pellet Inspection System PS25C

The Pellet-Scan-System PS25C (colour camera) from Optical Control Systems was developed for the qualitative and quantitative assessment of granules.

The system is suitable for
• Submission of granules as individual samples or from the production line by creating a by-pass
• Separation of contaminated pellets
• User definable colour/size classes and alarm limits
• Applicable for transparent, non-transparent and colour pellets
• Special applications using a UV light.

Application
The Pellet-Scan-System PS25C (colour camera) was developed for the qualitative and quantitative assessment of granules.

Within large scale polymer production, the high quality of the material is not just a question of ‘invisible’ characteristics. Even the outer appearance of the granules is of great importance. Regular granule shape and colour constancy greatly contribute to the safeguarding of quality during further processing. Aside from the aesthetic aspect, colour deviations can be an indication of hidden material defects. Recognising quality at the right time means a large contribution to competitiveness.

The PS25C is applicable for laboratory purposes as well as on-line inspection. The pellets can be submitted as samples or they can be withdrawn from the production line by creating a bypass. Using a bypass system gives the user the advantage of direct inspection of the material during the production process. This allows quicker reaction to any defects. The contaminated particles can also be extracted directly after the measurement (optional).

For the detection of contamination and foreign particles which show a different colour to pure, uncontaminated material, colour classes can be defined with the “teaching” tool. Furthermore, it is possible to define alarm limits. If these are exceeded, a floating contact is activated.

The inspection can be observed on a monitor and visible defects marked and indexed. Images of special importance can be stored and the results represented by a variety of graphics and tables. A colour printer documents the results. The data, software adjustments, the time and duration of the inspection can be easily accessed. This facilitates later evaluation or long-term evaluation.

The system can be integrated into any internal data processing by means of an existing software interface, e.g. via Ethernet. The unit is maintenance-friendly, as it is equipped with a fully automatic self-cleaning mechanism which cleans the pellet feeder and the optical chamber at various adjustable intervals.

Components
The unit consists of a 3-CCD-Chip colour camera, lighting, an image processor, a conveying device and a hopper. Equipped with a fully automatic self-cleaning mechanism which cleans the pellet feeder and the optical chamber at various adjustable intervals, it is very maintenance-friendly.

Mode of Operation
To find and eliminate the cause of certain defects, it is essential to have the most precise information at hand, through obtaining exact and continual details about the colour, size, frequency, etc. of certain defects.

The PS25C is capable of inspecting transparent and opaque granules. The images are taken with a 3-CCD-Chip colour camera and are processed and evaluated by the image-processor using specially designed software.

Software
This software offers a multitude of adjustment options, enabling the user to configure the system exactly according to individual measurements.
