A separating device for a gravity conveyor, comprising a conveying plane (E) along which an item (30) is conveyable in a conveying direction (F), and an actuating means (50), which comprises a first actuating member (51), which can be moved into an actuated position by conveyed items (30) being moved in the conveying direction (F), and a second actuating member (52), which can be moved into an actuated position by conveyed items (30) being moved counter to the conveying direction (F). When at least one of the first and second actuating members (50, 51) is actuated, a movement of the at least one separating stop (40) from the position above the conveying plane is blocked, and when the first and second actuating members (50, 51) are unactuated, a movement of the at least one separating stop (40) to a position below or flush with the conveying plane is enabled.

A speed limited rotational member including a first member, a second member rotatable relative to the first member, and first and second brake elements. The first and second brake elements are pivotally mounted to the first member for both pivoting between a first position spaced apart from a cooperating surface of the second member and a second position engaging the cooperating surface of the second member for generating friction to reduce a rotational speed of the rotational member. The speed limited rotational member further includes at least one linkage connecting the first and second brake elements. The speed limited rotational member may optionally include a down pressure component.

An automatic electromechanical braking roller system includes a power drive unit (PDU) comprising a sensor configured to detect a speed of a unit load device (ULD), a controller configured to receive a speed signal corresponding to a speed of the ULD from the sensor, and an electromechanical braking roller (EBR) spaced apart from the PDU and configured to receive a braking signal from the controller in response to the speed of the ULD being greater than a threshold value. In response to the speed of the ULD being less than the threshold value, the EBR is configured to rotate freely about an axis in a first state. In response to the speed of the ULD being greater than the threshold value, the EBR is configured to reduce the speed of the ULD in a second state.

A roller brake comprising: (a) a roller shaft that supports one or more ends of the roller brake; (b) a roller tube extending over all or a portion of the roller shaft; (c) a magnet; (d) a conductor located opposite the magnet and the conductor being in communication with the roller shaft when the magnet is in communication with the roller tube and the conductor being in communication with the roller tube when the magnet is in communication with the roller shaft; and (e) an air gap separating the magnet and the conductor; and wherein the conductor includes one or more recesses that are an absence of material in the conductor.

A roller assembly comprises a housing having an outer surface attached thereto, and a braking arrangement positioned at least partially within the housing. The braking arrangement is configured to increase resistance to rotation of the housing proportionally to a load applied against the outer surface.
