Abstract
A drive roller unit for driving an article on a conveyor track has a mounting frame structure of which one end is mounted to a base pivotably about an axis extending transversely to the direction of movement of the article, and a cam control unit for raising the free end of the mounting frame structure. A drive roller is mounted rotatably in the mounting frame structure to engage with an article disposed thereabove, only when the mounting frame structure is in a raised position. An electric motor drives a main transmission arrangement having first and second outputs of which one drives the cam control unit and the other drives the drive roller by way of a further transmission arrangement. Of the two outputs it is only ever that one which is subjected to a lower braking moment that rotates so that when the drive roller unit is initially switched on the mounting frame structure is first raised by the cam control unit and then the drive roller is driven in rotation. The axis of rotation of the electric motor is perpendicular to the axis of rotation of the drive roller and the further transmission arrangement has an angle of 90.degree. between its input direction of rotation and its output direction of rotation.
