Internal Spray Detection

Detects unsprayed (bright) cans immediately after the internal spray machines

Sencon's SC7050 Spray Detector (like its predecessors SC7000+,SC7100) inspects wet lacquer inside beverage cans on the outfeed of the Lacquer Spray Machine (LSM), giving immediate warning of spray system problems and preventing bad cans from mixing with good ones. If a problem is detected, the offending spray machine is stopped, but the remainder continue with production to minimize interruption of production output.

  • Bad cans are stopped at the spray machine, reducing spoilage
  • Self calibrating, self learning
  • Selectable sensitivity level
  • Compact and self-contained
  • Minimal maintenance - just wipe clean each shift
  • User replaceable inspection window

Prevents unsprayed cans from entering the production flow

SELF-CALIBRATING, SELF-LEARNING

The sensor learns and stores a value that represents the ‘good can’. This value is constantly updated according to how many bad cans are found over time. The unit continually self-calibrates, compensating for the inevitable accumulation of lacquer on the detector window. The system is therefore adjustment-free, although the detector window must be wiped clean at the start of each shift.

SELECTABLE SENSITIVITY

The system is supplied ready to go, but it is possible to adjust the sensitivity. The user can increase or decrease the sensitivity (six levels) to find a setting where false rejects are still acceptably low yet the limits are tight enough to detect un-sprayed cans.

OPTIONAL CAN STOP

When the system detects a coating error, it sends a reject signal to stop the spray machine and drive the optional can stop. The can-stop will hold the suspect can in the trackwork preventing it from entering the production flow. Defective cans are manually cleared.
