How our innovation is original and how it fulfills a need in the market that hasn’t been addressed which increases productivity and leverages a novel technology.
Automated Inspection of tablets and capsules packed in blister in not a new requirement, but even today it is extremely challenging task for vision system designers. Since pharmaceutical companies are constantly coming-up with different colors of product (i.e. tablets and capsules) packed in various types of forming foil (i.e. Aluminum, PVC-Clear, PVC-Opaque, etc.)
Examples of few challenging products:
In addition to this pharm companies today requires high productivity with consistency in quality. So they are investing more and more on high speed machines but when it comes to inspections there is still a lag in productivity and consistency. One of the most important processes in handling vision systems is a teaching process. Teaching a new product in vision system is still a time consuming task and prone to human dependency specifically for bister inspection system. It requires expertise of users on every step, i.e. manually identifying of formed cavities, segmentation of tablet/capsule color, setting optimum tolerances to detect geometric and color defects. Also manual teaching in certain times is a time consuming process and also depends on user proficiency. Even after teaching there are various acceptance tolerances that user has to tune manually to get the optimum results.
After market survey of various blister inspection system available today and understanding pain points of users, our aim was to make this teaching process completely automatic including auto learning of acceptance tolerance. After a constant research and development efforts of 2 years, we developed an algorithm which works for most of the products packed in all types of forming foils. With this today all our customers are very happy with their productively increased drastically. E.g. certain products which took 7-8 hours of users for teaching products earlier, it just takes 2-3 minutes now, even though inspection consistency is maintained.
What are the unique features of this product/system/technology as it compares to existing solutions?
Blister pack inspection is all about color based segmentation of tablets and capsules, and then quantifying the segmented region by product geometry and color.
