Quality Control

Quality grading and defect capture at the line.

After packing, every carton runs down the line through an inline check scale and under a barcode scanner. The Robot terminal reads both, verifies the printed label is actually applied to a real, weighed carton — not thrown away or re-printed — and posts a book-into-stock transaction to the on-premise SCADA & IOT Server. This reconciliation between printed labels and dispatched cartons is the critical QC check that closes the loop.

Quality control at the line

An inline scale + scanner downstream of the packers reconciles every printed label against an actual, weighed carton. Cartons that don't match — wrong weight, missing scan, duplicate scan — are flagged before they leave the line.

Inline check weighing

  • Every carton weighed in motion as it passes
  • Out-of-spec weights flagged for review
  • Independent of the packer's weighing — closes the trust loop

Barcode verification

  • Overhead scanner reads each label as it passes
  • Confirms the label was applied — not thrown away or re-printed
  • Duplicate detection catches re-scanned cartons

Stock booking

  • Each verified carton automatically booked into stock
  • Linked to the original packer transaction by barcode
  • Real-time inventory always reflects what physically left the line

Reject & reconcile

  • Cartons without a valid scan are flagged and held
  • Weight mismatches against label spec are surfaced immediately
  • Daily reconciliation compares printed labels vs. shipped cartons

Why this QC check matters

Closes the print-to-ship loop

A printed label without a scanned, weighed carton is a missing carton — caught here before dispatch.

Trustworthy stock

Inventory always reflects what physically passed the QC point — not what was promised at the packer.

Independent verification

A second weight downstream of the packer protects against scale drift, mis-tare, and human error at the station.

Audit-ready

Every QC pass and exception is captured as a structured event — full traceability for export, retailer, and regulatory audits.
