PEARL X-RAY INSPECTION
For many years, InnospeXion has worked with on- and off-line inspection of miniature dosage devices in the pharmaceutical industry. Based on the experiences gained in this area, we have established a technology
that can satisfy the demands imposed for an
automatic pearl inspection system.
X-ray technology can also be used for pearl X-ray inspection, and process & product control of pearls. Our new and innovative X-ray systems push the pearl X-ray inspection level to the real need – to detect what is critical for process & product quality inspection.
THE VALUE OF LOW-ENERGY X-RAY TECHNOLOGY:
- reducing loss and making best use of raw materials
- better product classification and a better product price
- avoiding customer complaints
- a robust, reliable, and safe inspection technology
- hygienic design guidelines
The X-ray systems offered by InnospeXion for this application are adequate for in-line usage, at production rates of about 1 pearl per 2 seconds. Faster inspection is possible using one-sided
nacreous layer thickness determination.
The quality of pearls depends among others on the integrity and thickness of the nacreous layer. X-ray imaging at high contrast and high resolution is a valuable tool to disclose the quality of each pearl. The challenges are: (1) to achieve the sought X-ray quality relative to resolution and contrast; (2) to have means of automatically measuring the nacreous layer; (3) to have a mechanism for automatic positioning and X-ray imaging of each individual pearl, with a short cycle time.
The system is based on a microfocus X-ray source and a high resolution, high contrast flat panel detector (area imaging). A special feeding mechanism will hold a large number of pearls, which are inspected and measured/ characterized one by one for the integrity and thickness of the nacreous layer at pre-defined positions. In addition, the system will measure the diameter, roundness, defects, and other quality parameters. After inspection, pearls may be sorted depending on quality into separate outfeed lanes. Pearls are identified by system entering time and dimensions.
