Conveyor 22 presents an invention “Back-Track Tray” – to solve a common issue of returning details within automation applications.

The entire system consists of two conveyors, Up Line and Black Line 141 with two feeding trays, one delivering tray and one returning tray. The unique motion created by linear conveyor Black Line, together with the force of gravity, enables Back-Track Tray to transport the details backwards.

Firstly Delivery Tray moves the details forwards for the purposes of viewing, picking or placing in a fixed position. Then unpicked or defective parts are gently returned by Back-Track Tray to the magazine. Lastly Up Line returns the details to complete circulation.
