Defective tablets caught on camera
Smooth, continuous tablet feeding achieved through a revolving precision ground glass disc on KBW's model AC2000 tablet counter has enabled a camera system from PCE to offer two-sided tablet inspection above and below the product.
Smooth, continuous tablet feeding achieved through a revolving precision ground glass disc on KBW's model AC2000 tablet counter has enabled a camera system from PCE to offer two-sided tablet inspection above and below the product.
Black and white inspection of both tablet surfaces, looking for black spots or other visible contamination, is available. It is possible to detect small and high-contrast contamination on both surfaces up to a minimum 0.1mm.
The camera system can inspect 10 products per second or 36,000 tablets per hour. As an additional option, the sides of the tablets and the resolution for the contamination of single tablets can be increased.
Tablets are separated mechanically as they are fed onto the table and while being transported to the camera so that they can be detected singularly and ejected in the case of a defect.
Defective products are ejected by a high speed air pressure mechanism, which is able to work at 20 pulses/sec, and collected in a separate container.
The camera system generates failure statistics and can store the last images of defective tablets in order to run analysis later on.
