HEUFT canLine II

And even if the closure succeeds, defects such as interrupted, indented crimped edges can jeopardise the tightness of the finished primary packaging and thus the microbial purity of the product it contains. The non-contact top-down inspection of the cans even before they are filled with just one sensor colour camera developed in-house, into which an adaptive LED illumination is integrated just as directly as a high-performance image evaluation, therefore not only realises a highly precise ovality detection in a very confined space, but also the identification of other deformations and defects around the container opening. Affected empty cans can thus be removed from circulation before they can lead to capping problems or become leaking full containers.

The HEUFT NaVi offers the user audiovisual step-by-step assistance which makes it easy to change the container type. The adaptive LED lighting, which is directly integrated into the sensor camera, also adjusts itself fully automatically to the changed sort, regardless of whether the cans have a diameter of 50, 90, 150 or 200 millimetres: For each type of empty can, the individually controllable LEDs automatically realise exactly the right, shadow- and reflection-free illumination of all areas to be examined. All grade settings are permanently stored in the system and can be reproduced at any time.
