Use a transversely mounted shaft to drive the rollers with o-rings.
Can run continuously.
Quiet and smooth, due to precision bearings.
Can handle a wide array of products.
Often seen in various manufacturing plants and distribution centres.
Motorized Driven Roller (MDR)
The future of accumulation conveyors.
Whisper-quiet.
Powered roller has internal electric motor that slave-drives a series of other rollers forming a zone.
Energy saving as they only run selectively in different zones.
Each zone is controlled using photo cells to detect product and drive cards to tell the drive roller when and how to move.
Easily configured. All cards can talk to each other so the first, last and all in between know their role and sequence.
Used for accumulation, often in distribution centres and where it is desirable to have a series of packages be back to front in a neat line.
Variable speed.
A variety of powered rollers are available running on AC and DC power depending on the application.
Chain Drive Live Roller (CDLR)
Heavy duty.
Positive drive.
Double sprockets welded to roller faces and rollers slave-driven off of each other.
Common in moving heavy loads like pallets, International Bulk Containers (IBCs) and Super Sacks.
Belt Driven Live Roller (BDLR)
Different types of belts (round, v, flat) used to drive rollers from underneath.
Positive drive.
Can be used to accumulate products in "zones".
Smooth running and quiet
Belt Conveyors - Types, Uses and Benefits
Fabric Belt Conveyors
Many widths/sizes available.
Belts available for most any application.
Various profiles available which can be adhered to the belt's top or bottom surface.
Common profiles are cleats, side flights and v-guides which interface with grooves on the pulleys to help the belt track straight.
Can move products with uneven bottom surfaces like an engine block for instance.
Standard and heavy duty options available.
Plastic Modular Belt Conveyors
Variety of belt types available.
Cleats and side flights can be used to lift product up an incline, control its descent on a decline or prevent it from falling off the side.
Common in food handling applications as it is easy to clean.
Also used in logistics and fulfillment.
Positively driven by sprockets like a bicycle chain.
Can be made to go around curves with specific belts.
Hockey Stick and Z-shaped Conveyors
Can be made with both fabric and modular belts.
Used to get product along a flat and then up an incline.
Common applications are take away conveyors from injection molding machines and in food co-packing plants transporting finished products from a packing or molding machine to other operations.
