label inspection system on rewind table

Rewind Table Label Verification System

Replace manual inspection with an automated system that detects smudges, misprints, and unwanted marks on every label, as well as verifying correct barcodes on labels.

How it Works

This vision inspection system uses deep learning, pattern matching, and optical character recognition (OCR) algorithms to recognize defects, inconsistencies, and incorrect lot and expiration information. It scans and processes labels at a rate of 1 label per second and alerts the operator to failed labels, which can be removed and recorded before continuing to inspect the remainder of the label roll. Inspection data is displayed on the HMI during the inspection process, including the number of labels processed, number of failed labels, and the number that passed visual inspection. The system includes a configurable recipe editor, allowing customers to input different inspections for different label types. 

Designed to work with a rewind table, you can seamlessly achieve 100% inspection while improving production speed and freeing up valuable personnel hours. Adhere to industry regulatory requirements, satisfy customer expectations, and improve your operational efficiency.

A Challenge Resolved

A major medical company performed manual inspections on labels for pharmaceuticals and medical serums at a rate of about 13 labels per minute, individually checking six different fields on each label. With serious implications for incorrectly labeling items for patients and falling short of pharma regulations, as well as an interest in saving upwards of $50k a year in increased efficiency, they turned to Artemis Vision to develop an automated label verification system.

The system processes labels for improved quality and compliance. And it improved inspection speed over 5 times, from 13 to 60 labels per minute.  With 600 dpi resolution and a 12-inch field of view, the system can now detect errors down to ~0.020”.  Valuable personnel hours have been freed up to use elsewhere, and inspection accuracy is assured and automatic.
