Shipped out last week, 3 X chain driven roller pallet conveyors with 3ph AC motors and low level stand systems.These conveyors were built for a pallet handling application where the roller conveyor has to transport wooden pallets that weigh 1500kg when loaded.
Normally on a gravity conveyors and systems where pallets are pushed along, accumulation is simple, but for powered pallet rollers conveyors it's not so easy.
One option is to use electrical controls and sensors to stop the rollers in certain areas where a pallet is present but this will involve multiple drives for chain driven pallet conveyors.
Through the use of driven rollers with chain sprockets and special internal roller mechanics, the pallets accumulate when they reach the yellow end stop.
