MIXED LABEL INSPECTION

Incorrectly decorated cans hold up production by creating quarantine situations, often called HFI (Hold-For-Inspection). This can be caused by rogue cans left on the line after a batch changeover or by poorly applied decoration. Detecting and rejecting these cans is vital for reducing HFIs and avoiding customer complaints. Even at speeds of over 3000 cans per minute, this mixed label inspection unit detects rogue cans left over from a previous design run. It may also detect cans with major decoration damage and defects such as “silver bullets” (bright cans). It has even proved successful at spotting color fades, voids, water spots and partial brights. The optional product tracker and rejecter ensures that these defective cans do not reach the customer or cause costly HFIs.
