ABSTRACT:
A roller conveyor has drive rollers individually connected to a stepping motor and idler rollers arranged longitudinally in two rows. The conveyor is divided longitudinally into a plurality of sections, each section being provided with a sensor and one of control cards that are sequentially connected and can exchange signals such that objects can be transported longitudinally on these rollers from one section to the next without colliding each other. Each drive roller has a wear-resistant lining around the drive shaft of the associated stepping motor such that the drive rollers can start and stop rotation gradually even if the associated motors are started or stopped abruptly.
