Roller Conveyors - Types, Uses and Benefits
- Ball Table
- Many types and sizes.
- Often seen in warehouses distribution centres.
Motorized Driven Roller (MDR)
- Powered rollers.
- Semi-positive drive.
- Variety of speeds available.
- 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.
Chain Drive Live Roller (CDLR)
- The future of accumulation conveyors.
- 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.
Belt Driven Live Roller (BDLR)
- 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.
- 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
Plastic Modular 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.
Hockey Stick and Z-shaped 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.
- 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.
