Vision Sorting System
Sort by color, size, or defect at line speed.

A vision sorter removes defective, off-color, or wrong-size product from a moving stream. Cameras image every unit as it passes; software grades each one against your spec; air jets blow rejects off the belt into a separate bin. Operators no longer eyeball the line, the machine catches every unit, every shift, with consistent thresholds.
Step by step
- 01
Product enters on a vibratory feeder that spreads units into a single layer.
- 02
A line-scan or area-scan camera images each piece against a calibrated background.
- 03
Onboard software grades the image (color, dimension, defect) against your accept criteria.
- 04
Fail units trigger a short pulse from one of dozens of compressed-air nozzles.
- 05
Accepted product continues straight; rejects fall into a side chute.
- 06
Counts, reject reasons, and trends log to a touchscreen and optional Modbus/Ethernet for SCADA.
What's in the cell
- Vibratory feed tray or wide belt conveyor
- Line-scan colour camera (1k–4k pixel sensor)
- High-power LED bar (white, RGB, or hyperspectral)
- Industrial PC with vision software
- Air-jet ejector manifold with solenoid bank
- PLC + HMI touchscreen
Where it fits
- Fresh produce grading (tomato, chilli, beans, ginger)
- Tea leaf colour grading
- Plastic flake / e-waste recycling streams
- Coffee bean defect removal
- Cashew / nut sorting
- Garment QC for fabric flaws
Sized to your line
These ranges cover most installations, exact spec depends on your product, throughput target, and integration constraints. We confirm everything before quoting.
Drops into an existing conveyor with a 1.5–2 m gap. We commission on your product, set the colour/defect library, and train two operators on threshold adjustment.
Part of our machine vision systems
This station is one of many vision applications we build, from fabric inspection and code reading to measurement, robot guidance and PCB inspection.
