Luceo: Optical sensors for sealing operations

The new smart electro-optical system, which will be featured at interpack in May, obtains a contrast quality that very clearly reveals all the defects in the sealing zone--lack of sealant, bubbles, folds, broken tray, presence of contaminants, etc. A perfectly contrasted image, which shows the sealing bead in white and all the sealing defects in black, means that interpreting data is both simpler and more reliable. This allows the control unit to work at higher rates with a minimum margin of error. Another function provided by the new generation of sensors is real-time control of the sealing bead width and detection of any shrinkage that is too great related to sealing tool drift. In this specific case, the control unit is also able to generate a process alert that allows the operator to act in real time to correct the problem and thus anticipate the appearance of defective sealing.
