Line Shaft Conveyors:
They are driven by a rubber band wrapped around the driving shaft located under the conveyor and the roller. Each roller is only able to drive 5% of the weight of the product.
They are most beneficial when light to medium duty product is secured on a flat bottom, with a rim or with boards facing perpendicular to the roller. Line shaft coneyors are able to accumulate, stop or divert making them an extremely effective and versatile conveyor.
Chain-Driven Live Roller Conveyors:
These types of conveyors are best utilised where weight may be of concern. The rollers are driven by a sprocket & chain that allow the roller to drive under heavy load. A friction drive sprocket may be applied.
They are clutch activated and allow the sprocket to continue rotating while the roller is stationary. This prevents excessive wear on the chain, sprocket, roller and product. Applying the friction sprocket allows for accumulation and separation where necessary.
Larger diameter rollers (25mm to 90mm) are available with chain driven live rollers as pallet handling or heavy product (in excess of 2000kg) may be conveyed.
Various sprocket diameter and types may be used in the one system to create separation by speeding up the rollers or reduce the separation by slowing them down.
Timing belt sprockets are used when high speeds (above 45m/min) are required.
