Vision inspection of decorative candles

For a leading manufacturer of decorative candles, we developed a comprehensive, multi-stage system for product inspection. In the project we used components from Datalogic and Keyence

Decorative products are subjected to detailed inspection for aesthetic values – including correct printing, central position of the wick (accuracy of up to 1 mm and 5 degrees of deviation), proper flooding (even up to 1 mm in height) or mechanical damage.

Moreover, such features as correctness of the label – its position as well as correctness of data and barcode – are controlled.

The system is equipped with a functional operator panel. It allows to:

  • Display of inspection results with photos,
  • Display of general and detailed statistics of rejected items,
  • Display of images of last rejected pieces,
  • Making changes to the vision inspection settings.

When the system detects a defect, the candle is removed from the line with a pneumatic ejector.
