Rejects handled
Following UPM conveyors being selected to design, install and commission a fully automated product handling system for Lindal Group in Mexico – which transfers injection moulded components to assembly hoppers located on GIMA machines for production of aerosols primarily for Unilever – the company now been awarded preferred supplier status to Plastek UK and Nypro Ireland for similar Unilever applications.
Each moulding machine has an under press reversing reject belt conveyor, which operates via the machine SPC control to ensure only good product is transported via swan neck belt conveyors to high level conveyors, then through a fire wall to assembly/filling lines.
Should the reject parameter from the SPC be activiated the under press conveyors reverse, transporting potential rejects to a holding bin and ensuring only good product is transferred to the GIMA assembly machines.
Total versatility of operation is provided for all products from injection moulding machines to be transferred to the fully automatic assembly and packaging machines without any manual involvement.
This is achieved by the incorporation of multi way diverters based on the conveyor design developed by UPM that resulted in its being awarded the Queens Award for Innovation.
