LEWCO offers a number of conveyors that utilize 24 volt DC technology,
including chain driven live roller, belt driven live roller and chain
conveyor models. They provide rugged conveying capability along with the
advanced technology of 24 volt DC drives to provide zone accumulation.
With this technology, zero pressure zoned accumulation conveyors can be
constructed without the normal limitations found with most O-Ring drive
conveyors.
In a recent application, LEWCO's customer required 24
volt DC driven conveyors to move engine blocks between machining
operations. LEWCO configured the chain roller conveyor for this
application resulting in an economical solution for a rugged environment
with metal chips and machine coolant. Having 24 volt DC motors directly
coupled to the conveyor rollers, each 24” long zone had sleep
functionality, allowing the drive to turn off when not required to move
product. The motor driver cards have complete zero pressure
functionality built within and are then daisy chain wired to adjoining
zones, thereby eliminating the need for PLC controls.
