The Optisort systems include various components such as the Optisort OTW test cell. The designs of the components can be individually adapted. (Image: Gefra)
Several machines have been produced based on this platform. They are identical to each other so that test plans and machine data can be copied between them.
The basis is the construction of the glass plate machine, equipped with various camera stations. One top and one side camera each with backlight for dimensional inspection, one borehole camera each from above and from below and one brightfield incident light camera each from above and below.
Gefra offers two machine base types: Optisort ST and Optisort W. The former is designed with a steel ring plate and is suitable for inspecting fasteners, screws, blind rivets and long rod-shaped parts. The Optisort W with glass disc inspects mainly flat parts such as nuts, washers and rivets. The machines process up to 1,800 parts per minute, depending on the size of the parts and the inspection task.

Optisort ST is particularly suitable for screw testing. Test range: Screw diameter from 1.4 to 18 mm. Length of screws up to 160 mm. (Image: Gefra) -
For flat parts with a maximum area of 90 x 90 mm and a maximum height of 130 mm, such as washers and nuts), the Optisort W was developed. (Image: Gefra)
