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.
