GENERAL FEATURES
QUALIPLASTQUALIPLAST
Check from the top (one camera):
-Measurements of circumference dimension and of possible inside seal
-Circumference shape (possible ovalization)-Flashes presence, comparing to a reference sample-Non uniformity or absence of colour (inside surface) -Correctness of the sealing cone-Presence of dirt spots inside the cap-Imperfections or material lack of the upper profile
Lateral Check (additional four cameras):
-Micro Imperfections or material lack of the upper profile
-Presence of flashes, even small, comparing to a reference sample. -Presence of dirt spots on lateral surface

WORKING PRINCIPLE OF THE SYSTEMReferring to Figure, closures from press are vehicled into centrifugal feeder fromwhich they come out set on conveyor belt , where by a dedicated device areproperly spaced. This way closures reach the control area where, at the moment asensor of presence provides signal, the images start to be digitalized and finallyprocessed by a dedicated software. Then closures reach the rejection area wherethe defective ones are rejected by using air compressed flow. The closuresunaffected by defetcs reach the conveyor end where they are packed . The Systemautomatically manages also the package change, once the forecasted quantity ofpieces packed .
