Optical Inspection System Automatically Inspects Coated and Uncoated Tablets at High Production Speeds

Symetix introduces the OptyxSG/P optical inspection system designed specifically for tablets. With an integrated dust abatement feature and KeyWare application software for tablets, OptyxSG/P automatically inspects coated and uncoated tablets at high production speeds to remove defects and foreign tablets (rogues) from the product stream.

The OptyxSG/P for tablets verifies product color, size and shape to automatically identify and remove products that do not conform to specifications. Inspecting tablets 5mm and larger at speeds up to 1,000,000 tablets per hour, the high resolution OptyxSG/P detects the smallest color and shape defects to guarantee removal of 100 percent of foreign tablets, while also removing broken tablets, stained tablets and tablets with missing coating if the coating is a different color than the underlying tablet.

OptyxSG/P can be cleared, cleaned and set-up to handle the next product run in less than 30 minutes. With product settings stored in memory for quick and easy recall via the icon-based graphical user interface (GUI), OptyxSG/P reduces operator training and simplifies optimum operation. The GUI can reside locally on the system and can be accessed remotely via network or Internet. 

The OptyxSG/P is FDA 21 CFR part 11 compliant with secure and encrypted logs, secure passcode management, a Freeze on Reject (FOR) feature, parameter histograms and guided changeover. A number of self-aware features include Eject Function Confirmation (EFC) and intelligent sensing for belt speed, belt tracking, proper change parts and failure of any system lamp or ejector valve.

OptyxSG/P uses proprietary color cameras to view product — four primary inspection cameras are located both above and below the product stream. Symetix image processing technology quickly analyzes the product images, comparing each object to previously defined accept/reject standards.  When a defective product or rouge is identified, the system activates the close-coupled high-speed ejector system to remove it from the acceptable product stream.

OptyxSG/P features a parallel processor that enables operators to monitor images of every object of interest acquired by OptyxSG/P, such as rogue objects failing inspection. When a rogue is encountered, the inspection system can stop the product flow, and all the objects that are classified as rogues are presented to the operator and stored in the batch log file. This functionality guarantees rogues are eliminated from the product stream.
