Abstract:
An arrangement for moving material to be conveyed along a conveying plane, comprising:a conveying plane formed by driveless running rollers serving to carry and guide material to be conveyed;said conveying plane having a drivable conveying roller, which is arranged between the driveless running rollers;a control-electronics part for controlling a first drive driving the conveying roller;said conveying roller being connected to said first drive and an associated first activating unit for producing a requisite traction force for moving the material to be conveyed along the conveying plane;said conveying roller also being connected to a second drive having an associated second activating unit for producing an adequate pressure force of the conveying roller against the material to be conveyed;wherein the first drive and the second drive can be activated independently of one another, and can be coordinated by the control-electronics partand wherein the conveying roller, in the form of a hollow cylinder, is mounted on a cylindrical supporting body such that it can rotate about the axis of symmetry of the latter; said first drive being connected to the conveying roller via a gear unit located inside the supporting body; the supporting body being mounted such that it can rotate about an eccentric axis running parallel to its axis of symmetry, and the second drive is coupled to the supporting body for pivoting the supporting body about its eccentric axis and for pressing the conveying roller against the material to be conveyed on the conveying plane.
