The importance of classifying and sorting in pharmaceutical operations

​​Classifying and sorting pills, tablets, and capsules involves identifying and categorizing tablets based on attributes like size, shape, color, and coating.

​Sorting sends each item to the correct destination, ensuring properly identified, quality-assured tablets go to packaging. AI-powered vision systems provide fast, reliable performance -- enabling precise counting and real-time classification. This technology is essential to support regulatory compliance and ensure every unit meets quality standards.

​​Overcoming challenges in high-speed tablet classification​

​​Traditional oral dosage processes are labor-intensive, error-prone, and often struggle to handle the visual complexity of tablets, pills, and capsules.

Pharmaceutical manufacturers face several challenges:

  • ​High-speed production demands precise counting and routing without bottlenecks
  • ​Tablet variability in shape, coating, and reflectivity
  • ​Irregular orientations make consistent identification difficult
  • ​Tablets stuck together can cause miscounts or skipped units on high-speed conveyors

​​Cognex machine vision systems solve these challenges using powerful image formation technology, AI, and robust lighting and optics.​
