Tablet visual inspection system TVIS-EX4-CD

Tablet visual inspection system

Equipped with image processing system V-IPU
HMI, work control, and image processing are integrated into one unit to achieve highly accurate, high-speed image processing.
The extensive image processing library makes it possible to set specialized parameters for different types of defects. This enables to detect defective features that were difficult to detect in the past.
Adding algorithms
"Adding an algorithm", which was difficult with the conventional image processing board base, has become extremely easy with the adoption of V-IPU.
High-accuracy 3D inspection (Nakai Prize winner)
Compared to conventional ring lighting, there is almost no noise on 3D image.
The system is also able to detect emboss or chipping without being affected by the tablet's color or mottled pattern.
It is possible to detect small chipping that were difficult to detect by conventional methods at high speed.
We are recognized for our high level of contribution to quality assurance and productivity improvement in the pharmaceutical manufacturing process, we won the Nakai Prize of the Japan Society of Pharmaceutical Machinery and Engineering, the highest in the industry.
