Sorting & Rejection Systems

Classify products as OK / NG and trigger reject mechanisms, counters, alarms, or process-control actions — so a vision decision turns into a physical result on the line.

Inspection that does something about it

Finding a defect is only half the job. If the rejected part still reaches the next station, the inspection achieved little. The decision has to reach the line in time to act.

We integrate vision with your PLC, reject actuators, and controls so each OK / NG result triggers the right action: air blast, pusher, diverter, alarm, or line stop. Reject tracking, counters, and trends then show where defects start.

What we connect

The vision result drives the line through whatever interface you use.

OK / NG Classification

Grade each unit by pass / fail rules or into multiple grades.

Reject Mechanisms

Fire air blasts, pushers, or diverters at the right moment.

Alarms & Stack Lights

Alert operators on a defect streak or station fault.

Counters & OEE Data

Count good, bad, and total units per shift or batch.

Tracking & Timing

Use encoders or shift registers to reject the exact unit.

Process Control

Send trends back to the line to adjust before defects spread.

How the setup changes with the line

A quick sense of what typically drives the setup — the exact tools are always tuned during commissioning.

Fast Conveyors

Encoder-based tracking so rejects hit the exact part, not its neighbor.

PLC-Integrated Lines

Digital I/O or industrial Ethernet for signals, recipes, and results.

Multi-Grade Sorting

Several output bins by defect type or grade, not only OK / NG.

Reject Verification

A second sensor confirms the reject actually left the line.

Logging & Traceability

Each decision and image is stored with a timestamp and batch ID, so rejects can be reviewed and traced to their source.

Rejecting faulty packs without stopping the line

Defective packs were pulled off by hand, and some slipped through. An encoder-tracked air-blast now removes each NG pack automatically.

Sorting molded parts into grades

Operators sorted parts by eye into good, rework, and scrap. A camera now grades each part and sends it to the right bin.

Stopping the line on repeated defects

A run of bad parts went unnoticed for minutes. The system now raises an alarm and stops the line after a set defect streak.
