dSort 4s

Automatic sorting machine for large stretchable parts.

Doss Visual Solution’s automatic sorting machine for large stretchable parts. The core of the system is the vision unit, consisting of four linear cameras. The parts arrive on the conveyor belt and are taken by two pulleys, placing them in front of the cameras.

The cameras inspect all the surfaces while each part is stretched and rotated. Report and statistics of all pieces inspected are available for the operator. Upon request, a camera system to inspect the dimension or a point-to-point laser to measure part’s thickness can be added.

See how this machine works by watching our short YouTube video here.

If you’re interested in another visual inspection machine great for large o-rings and rigid frames, see our dSort 5 model.
