Tablet automated Visual Inspection System
Tablets fed to the hopper are transfered to the flow-control turntable in approproaite amounts by the vibratory feeder. The tablets are lined up by several guides and transfered from the transfer sub-system to the conveyer and inspection sub-systems at an optimum pitch.
Tablets fed to the inspection sub-system pass through the lighting units installed on the conveyer unit and images of each surface of the tablet are picked up by the CCD line sensor cameras.
The images are processed to obtain various data and individual tablets are judged acceptable or defective according to the unique inspection algorithm.
When an substandard tablet is encountered, the image processing system sends a rejection command to the rejection sub-system, discharging defective tablets into the defective tablet collection box pneumatically. Acceptable tablets are fed directly to the accepted tablet collecting gate.
