Automated Logo-Based Sorting of Lids Using Machine Vision

A sensor-triggered vision system that recognises the printed symbol or logo on each lid, sorts lids by pattern, and uses pneumatic rejection for lids that match no category or are defective.

Application

Automated logo-based sorting in lids

The Application

Sorting lids by printed logo — and rejecting the rest

Vision systems are essential in packaging for accuracy, quality and efficiency. They automate inspection tasks such as logo recognition, logo verification and defect detection, which are difficult and error-prone when done manually.
By detecting misaligned or incorrect prints early, the vision system reduces waste, prevents defective products from reaching customers, and keeps product quality consistent while speeding up production.

Key Factors

Performance at a Glance

Automatic classification and sorting on the packaging line

Logo

Symbolic / logo pattern recognised on every lid.

Pneumatic

Lids routed to designated bins or rejected by air.

Real-time

Decision made as each lid passes the inspection station.

Operation

How the inspection works

Lids are inspected for printed symbolic or logo patterns and sorted automatically as they pass through the inspection station.

01

Sensor trigger

A sensor triggers the camera as the lid passes through the inspection station.

02

Pattern identification

The camera captures an image of the lid and analyses it to identify the symbolic pattern.

03

Category match

If the pattern matches the predefined category, the lid is allowed to proceed.

04

Pneumatic sorting

Lids of another category are routed to their designated bin; defective or unmatched lids are pneumatically rejected.

Final Result

In-Sight vision software running on the line

Line HMI running In-Sight vision software — lid classified OK

Technology Used

Hardware behind the inspection

Cognex IS2801M

Vision camera that captures each lid and classifies its symbolic / logo pattern.

Proximity Sensor

Detects each lid and triggers the camera at the inspection station.
