Sheet Registration Measurement Option

Skew, or slight rotation of sheets as they go though the coater is not the only problem that can occur with sheet alignment and coating placement. Some sheets will also arrive either early or late to the coater if the infeed grippers don’t catch the sheets properly. The misplaced coating produced leads to waste and customer quality complaints.

By adding Sencon's SC450 Sheet Registration Measurement Option to the SC415 Skew Measurement System, these problems can be kept to a minimum.

Reduced Spoilage - If sheet alignment is monitored with the SC415 Sheet Skew Measurement System, the occurrence of lacquer in the weld area is minimized and faults in the welding process are reduced. Adding the SC450 Registration Measurement Option also alerts operators about sheet feed problems which would result in misplaced cross margins and spot coatings.

Reduced Machine Downtime - If weld margins are not squarely aligned and registered properly, the chances of wire breakage at the welder and poor product quality will be significantly increased. By checking both squareness and registration, the main causes of downtime through weld wire breakage and customer complaint will be significantly reduced.

For skew, accuracy is better than 0.2mm (0.008"). For registration accuracy is better than 0.1 mm (0.004”). For both, this accuracy is achieved at operating speeds of up to 9,000 sheets/hr. This allows 100% inspection of sheets at high speed.

Better Can Quality - By ensuring correct alignment and timing of sheets entering the coater, can quality will be improved.

Process Improvement - The SC415 Skew Detector combined with the SC450 Registration Measurement Option (also see the SC430 Sheet Translation Option) gives you all the tools you need for a comprehensive coating process improvement program. By cutting out the need for manual measurements and giving immediate feedback as sheets as go through the roll, the SC415 / SC450 combined system enables:

• Quicker changeovers
• Reliable roll Alignment
• Faster production rates without the
  risk of extra scrap
  

By continuously monitoring and analyzing data, as well as giving predictive warnings before problems occur, the SC415 / SC430 combined system Faso helps to:

• Make effective process improvements
• Promote better operator training
• Increase plant efficiency
