Empty Cans Inspection

Finish and flanged edge inspection

Detecting deformations and safeguarding sealabilty: full line efficiency and packaging integrity when filling cans.

Misshapen, distorted and dented: empty cans with shape deviations in the neck area or indentations in the flanged edge jeopardise the efficiency and productivity of the filling process as well as the tightness and integrity of the full container. For example the lid will not fit on the can if the upper opening of the empty can is oval instead of round. The result: blockages in the closer which can lead to downtimes which slow down the productivity of complete can lines. And defects such as interrupted, dented flanged edges can endanger the tightness of the finished primary packaging material and thus the microbial purity of the beverage inside even if the sealing process was possible.

Product monitoring and self-tests

Playing it safe:  exact product tracking and regular self-tests.

Always knowing the current location of a particular product:  each one is tracked precisely for this.  This ensures that none remain uninspected.

Easy brand changes

Adapting automatically: self-acting and assisted format changes.

Brand and format changes are the order of the day along canning lines. The higher-level HEUFT SPECTRUM ^II platform on which the HEUFT canLine II is based already has an unprecedented level of automation and support for the user in order to carry them out quickly, easily and without errors: the height of the intelligent colour sensor camera is adapted to the new container format just as automatically as the passage width of the guide rails in the inspection area. The HEUFT NaVi provides the user with audiovisual step-by-step assistance in the course of this which makes brand changes simply easy. The innovative adaptive LED lighting which is directly integrated in the sensor camera also adjusts completely automatically to the changed brand regardless whether standard beverage cans, sleek or slim cans in a wide variety of colours: the individually controllable LEDs automatically provide exactly the right illumination without shadows or reflections for all the areas to be examined for every type of empty can. All the brand adjustments are permanently stored in the system and can be reproduced at any time.

Optional additional functions

Detecting even more:  extensions to the range of functions.

The HEUFT SPECTRUM ^II systems with their modular design are easy to expand. Thus the range of functions of the HEUFT canLine ^II can be optionally expanded with a compact, safely encased detection unit for, among other things, an optical inspection of the outer walls. In this way scratched, misprinted, incorrectly marked and non-brand cans can be tracked down and sorted out even before they are filled. The high-performance image processing system with teaching in capability remembers individual quality requirements in the course of this. This ensures that only those cans reach the market which have a perfect appearance and have been filled with the correct brand.
