Electromagnetically operated coupling, for drive train of conveyor, has driving pulley pressed against fixed friction surface to brake conveyor staged and against drive pulley friction surface to drive conveyor stage
Electromagnetically operated coupling, for drive train of conveyor, has driving pulley pressed against fixed friction surface to brake conveyor staged and against drive pulley friction surface to drive conveyor stage
The device has a drive pulley continuously driven by a main drive belt and a coaxial driving pulley for a conveyor stage driving belt. The conveyor stage can be switched on and off, has friction linings on both sides and is movable between the drive belt and a frictional surface fixed to the coupling so the driving pulley can be pressed against the fixed and drive pulley friction surfaces to brake and drive the conveyor staged respectively. The device has a drive pulley (8) continuously driven by a continuous circulating main drive belt and a coaxial freely rotatable driving pulley (11) for the driving belt of a conveyor stage. The conveyor stage can be switched on and off, has friction linings (16,17) on both sides and is axially movably arranged between the drive belt and a frictional surface (15) fixed to the coupling so that the driving pulley can be pressed against the fixed friction surface to brake the conveyor staged and against the drive pulley friction surface to drive the conveyor stage.
