Online Acoustic Wave Sensing for Paperboard Score Quality Control
Inline acoustic wave sensing detects sub-surface paperboard delamination during scoring, stopping un-creased board defects before downstream cartoning line jams.
Inline Web Inspection
Optical Detection
High speed image acquisition hardware monitors continuous substrate movement during high volume converting operations to identify surface irregularities. Inline web inspection utilizes light arrays and sensitive cameras to scan material surfaces for microscopic holes, color shifts, or structural defects as the sheet travels through a production line. Automation logic processes these visual data streams against predefined quality tolerances to trigger corrective actions or alerts.
Real time identification allows operators to remove contaminated material segments before the stock reaches further value added processes like lamination or final cutting.
Defect Threshold
Sensor calibration establishes the minimum physical dimensions for a fault to warrant system rejection. Signal thresholding differentiates between minor aesthetic variations and critical structural flaws that threaten the integrity of a final packaging product. Differences in reflected light intensity allow the system to map features across the width of the substrate with sub-millimeter accuracy.
Complex algorithms filter out noise from harmless debris or dust to maintain focus on true substrate degradation. Statistical tracking of detected fault frequency provides data for adjusting upstream process settings to improve overall manufacturing yield.
Performance Metric
Production consistency depends upon the fidelity of the visual map created during the passage of raw materials through the inspection zone. Optical systems generate comprehensive archives of defect coordinates that correlate with winding stations to simplify the removal of faulty rolls. Accurate coordinate tracking minimizes material waste by permitting precise surgical excision of compromised sections rather than discarding entire batches.
High resolution monitoring provides an objective record of output quality that satisfies internal and external requirements for supply chain accountability. This technology minimizes the risk of delivering substandard substrates to automated filling or print facilities.
