Visual Inspection
100% In-Line and Off-line Automated Visual Inspection of Packages:
- Measurement System is a computer based automated system that, taking images of Packages, visually inspect them to detect visual defects
- Works on a broad range of Package systems – empty / filled with liquid or powder e.g.:V
- Vials
- Bottles
- Ampoules
- Pre-Filled Syringes and Cartridges
- BFS / FFS
- IV Bags
VI is accomplished by the following tasks:
- Images Acquiring: A suitable collection of images of the Package are acquired using video cameras
- Image Processing: Defects on the Package are identified and/or measured by using dedicated image processing algorithms
- Decision Making: Packages classified as defective (Non Conforming) are rejected, Packages classified as complying (Conforming) are approved
Cap Inspection
- Detection of: Stopper absence, Defective Crimp, Dents, Flip Off Deformation and Wrong Color, Cap Scratches and Deformations
Cosmetic Defect
- Detection of Scratches, Deformations, Glass defects
- Function:
- The Package is spun for at least 360° along its vertical axis while passing in front of the respective Camera
- Strobe white lights are switched on and off for each and every acquired image
- Detection of wrong Fill Level and Liquid Color
- Function:
- Fill Level is evaluated by a dedicated ROI; meniscus position is calculated and compared to preset threshold ± tolerance
- The color of Liquid product within the Package is identified through a dedicated ROI and by using the RGB color model
Foreign Particulate Matters
- Detection of Particles and Fibers (reflecting and non reflecting)
- Function:
- The Package is provided with a Fast Spin along its vertical axis and then stopped abruptly in order to create a vortex in the liquid content
- During the passage in front of the Cameras with the Package still and the liquid in rotary motion, a set of images is acquired.
- Strobe light switches on and remains in this condition during the images acquisition process
