PHARMACEUTICAL PACKAGING INSPECTION
Packaging inspection in the pharmaceutical industry is one of the main applications for low-energy X-ray systems. Vision systems have previously gained wide acceptance for industrial quality control. The present X-ray detectors with speed of up to 300 images per second allow, together with faster computers, that X-ray data is usable for the control of processes in industrial production. The starting point is the quantification of information of the X-ray images.
The incorporation of PLC-based control in the X-ray systems enables a more complex and safe online quality control.
THE VALUE OF LOW-ENERGY X-RAY TECHNOLOGY:
The motivation for the use of low-energy X-ray systems is in this way not solely as a method for detection of foreign particles – but a more complete online quality control.
DEPENDING ON THE PRODUCT, SHAPE, SIZE, AND PACKAGING MATERIAL,
LOW-ENERGY X-RAYS CAN BE USED TO CONTROL AND MEASURE MANY DIFFERENT ASPECTS OF A PRODUCT:
- Is the package intact?
- Are labels placed correctly?
- Is the package correctly closed? (is the plastic weld free of foreign particles etc.)
- Is the product correctly placed in the package?
- Are all units in the package?
- Is the distance between packages/objects on the line correct?
- Is the product correct and does it look “normal” (without flaws)?
- Are there any foreign particles – and if so, where in the package?
- Is there a correct amount of the product?
