Abstract:
1. A clutch/brake unit for an accumulating conveyor for driving and for braking at least one roller which is provided for transporting a unit load on a roller path of the accumulating conveyor by means of an endless traction mechanism, wherein the clutch/brake unit is driven continuously during operation via an endless drive traction mechanism on a driving roller and is configured, in an engaged operating state, for transmitting the rotational movement of the driving roller about an axis to a driven roller and, in a braking operating state, for slowing down the driven roller on a housing of the clutch/brake unit, the driven roller being connected to the roller via the endless traction mechanism, wherein first actuating means are configured for displacing the driven roller along the axis in the direction of the housing in order to shift the clutch/brake unit into its braking operating state and wherein second actuating means are configured for displacing the driven roller along the axis in the direction of the driving roller in order to shift the clutch/brake unit into its engaged operating state, and wherein the first actuating means comprises a compression spring and the second actuating means comprises a piston/cylinder unit integrated in the clutch/brake unit, the piston of which rotatably supports the driven roller via at least one ball bearing while being guided linearly along the axis of the clutch/brake unit, and wherein the clutch/brake unit is guided with a depressurized cylinder into its braking operating state.
