ABSTRACT:
Sorting apparatus, e.g. for root vegetables such as potatoes, comprises a roller table conveyor which has an inspection area onto which a video camera is directed. An operator uses a hand-held probe or wand incorporating a light source and provided with a pressure-sensitive switch in its tip. The switch is actuated by touching a selected article in the inspection area. The position of the wand as indicated by light is given in the video signals fed from the camera to a control circuit to which the switch is also connected. The control circuit also receives speed indicating signals from the conveyor and it provides control signals to operate a finger bank to selectively deflect those articles indicated by a touch of the wand. Provision may be made for a plurality of wands to be used at the same time, each wand having an individually modulated light.
