Ensuring that the can can be closed, preventing seaming blockages and the resulting loss of productivity, detecting and rejecting faulty and contaminated packaging in good time before filling: the HEUFT canLine II carries out a precise quality inspection of up to 1,200 empty beverage cans per minute – and even finds faults in the inner shoulder area which is difficult to see with the help of smart new additional optics.
It can identify deformations, indentations and defects at the crimped rim of the mouth of empty cans just as reliably as dirty and dented inner walls or contaminants and foreign objects at their base. All this is carried out by the compact HEUFT canLine II with only one HEUFT reflexx A.I. camera in a top-down arrangement in which the smart image processing for the targeted object detection and classification is directly integrated. The colour sensor camera including completely integrated image converter technology and adaptive LED illumination achieves such a depth of field that no critical defect can be overlooked.
The compact system can now be extended by an additional detection unit in order to ensure that the empty can inspection also completely covers the sloping inner shoulder area just below the can opening which is difficult to see: Based on the HEUFT FinalView II CAP technology for the 360° closure inspection this generates a total of eight high-resolution camera views from exactly the right perspective directly on the conveyor which show the sensitive area below the rim of each individual can all around.
Even the smallest damage, adhesions and contamination such as material defects, coating faults, oil or grease residues and stains are reliably identified there in conjunction with the HEUFT reflexx A.I. image processing. And this also during the minimal distance between the individual containers on the conveyor.
The superordinate HEUFT SPECTRUM II platform on which the HEUFT canLine II is based realizes the highest degree of automation
