The Colorvision/Pacvision system is a flexible vision inspection system mainly designed for fill control of blister packs in blister packaging lines of similar thermoforming and packaging applications.
The system can inspect and verify tablets, multicoloured capsules, dragées, ampoules with colour ring codes, syringes and similar products packed in a pattern. Other similar but more complex applications are found with display cases for toys etc.
The system is designed to be very flexible and at the same time very easy and simple to use. It is operated via an interactive track-ball / screen dialog where the operator manipulates texts and graphics to adjust the system. The menu text is deliverable in several languages.
The vision functions in the system includes:
- Colour distribution verification
- Size and position verification
- Automatic learn and placement functions
- Pixel counter tools
- Shift register
By combining these tools properly it is possible to create optimum inspections on most blister machines on an unlimited range of products.
Using the inspection tools it is possible to inspect blister packs for a number of defects:
- Missing products
- Partly missing or defect products
- Wrongly placed products
- Wrong colour or discoloured products
- Products outside pockets
Defect blisters will be detected if they do not meet the specified tolerances. Empty blister packs and/or blister packs containing wrong coloured products and/or products outside pockets can be rejected separately subject to system settings.
The first ColorVision / PacVision system was delivered in 1989 and several generations of the product exist. These systems are being phased out. The more modern and powerful system VisioChrom / VisioPan with added speed and new advanced tools but also including the same basic functionality is now the preferred system for this type of applications.
