Abstract
A roller conveyer system employs a plurality of driven roller assemblies. Each driven roller assembly comprises a roller and a driven pulley, wherein the driven pulley is connected to a driving device, such as a drive motor via a drive belt for transmitting driving torque. On the other hand, the roller is frictionally cooperates with the driven pulley so as to be driven by the driving torque transmitted from the driven pulley. An auxiliary driving mechanism may be provided in the conveyer system for driving some of the driven roller assemblies. The auxiliary driving mechanism is variable of the driving speed so as to facilitate rapid stop and feed of the object at each production station.
