What Are Roller Conveyors
A conveyor system is best for transporting materials and is used widely in industries. Conveyors help in moving bulky and heavy materials. These machines come in handy particularly for remodeling work where heavy debris need to be removed from inside an existing structure.
A modular design of the conveyor line makes carriage of materials round corners easier. Also the length and position of the line can be adjusted according to the working area. Movement of materials to and from a construction site is made easier, hassle-free and economical with conveyors.
The powered roller conveyors are very popular among the common conveyor variants, particularly in the warehousing and logistics industry. They are more robust and durable than belt conveyors and can carry the heaviest of loads. The rollers move on bearings and pre-lubricated bearings minimize maintenance cost to a great extent. Some manufacturers supply this type of low-maintenance bearings.
The rollers used in conveyors are made from mild steel, stainless steel, PVC or aluminum. The Food processing industry uses stainless steel or PVC rollers which are custom designed to spray water, thereby washing the materials being carried. Rollers used in conveyors are of various types:-
Gravity rollers
High speed or low noise rollers
Grooved Rollers
Corrosion resistant rollers
Chain Driven rollers
Roller conveyor systems used in the manufacturing and distributing applications are of three major types. The choice of the system is based on the purpose of its usage.
Gravity roller conveyors are non-powered and the rollers are supported on shafts by bearings. Formed or structural punched frames contain these shafts by either retaining pins or internal springs. Since the roller conveyor is driven by gravity, the product can be free-wheeled manually (horizontally) or the product can be allowed to fall over a certain distance with a slight decline.
Lineshaft roller conveyors have a single shaft that runs below the rollers for the length of the conveyor frame. On the shaft there are a series of spools; one spool for each roller. Rubber o-rings run from spools on the powered shaft to each roller. The shaft is then powered by an electric motor and the rubber o-ring acts as a chain between the spool and the roller causing rotation. The rotating of the rollers pushes the product along the conveyor.
Pallet roller conveyors consist of thick walled rollers with sprockets attached to the ends that connect the rollers to the motor and facilitate the rotation of the rollers. Driven by chain to chain or tangential, or one common chain, drive mechanism, pallet roller conveyors have a fully enclosed side frame and an external shaft mounted motor. These have electronically switched “accumulation zones” and different sections of the conveyor can effectively run at different speeds, or stop altogether, independently of one another.
