Packaging Inspection for Food- and Pharma-Industries

The inspection of packaging in industries such as food and pharma are important because:

  • The consumer is more and more aware of quality, especially when buying food or pharmaceuticals. A sufficient inspection of the packaging increases the customer's confidence.
  • For automated inspection also mechanical engineers are more and more convinced of image processing solutions, as machine vision technology has advantages for productivity and efficiency.

 

Solutions with EyeVision

The EyeVision software is the evaluation software behind the smart cameras or also behind PC-solutions. Together with hardware, which supports EyeVision, several inspections can be carried out:

 

- detects errors in transparency film and heat-sealed joints

- the correct position of printed backing film and labels 

- the expiration date

- the bar code and the print layout

 

 

Example: inspection of ketchup packets

One application is the inspection of ketchup packets. The software checks the packet for:

  • Expiration date
  • Sealed seam
  • Imprint
  • Bar code, etc.

The visual packaging check is not only concentrating on the sealed seams of the bags, but it also checks if the bar code is readable and the expiration date is printed correctly. Also the presents of the cutting to make it easier to open the bag.

The visual check inspects the package from front and also bottom. The EyeVision software, combined with one of the EyeCheck smart cameras inspects and evaluates the sealed seam. Therefore not only loose and leaky seams can be detected, but also other defects such as deformations and entrapped air. Also errors in the printing and unreadable bar codes.


To top that the EyeVision software is extremely user friendly, as for creating an inspection program with the drag-and-drop function of the user interface, does not require programming skills.

Example: rasin packets

The Software checks that only correctly produced and packed raisin snacks are delivered to the shops. The visual check not only concentrates on the latch and the otherwise unharmed packaging, but EyeVision also can read the bar code and the expiration date.
