A separating device for a conveyor system for conveying piece goods in a conveying device on a conveying plane, - the separating device comprising a stop for the piece goods, and a control element; - the control element, as a result of contact with the piece goods occurring in the conveying plane, being rotatable about an axis that is oriented parallel to the conveying plane and perpendicularly to the conveying direction; - a movability of the stop between a separating position and a conveying position, as well as a blockage of the stop in the separating position, being controllable by the control element as a result of the rotation; - the stop being movable by the control element as a result of the rotation; and - the control element being mechanically coupled to the stop by way of a pull rod, the pull rod being movable in and counter to the conveying direction as a result of the rotation, the stop comprising a stopping claw and a bar, - the stopping claw being rotatable about an axis that is oriented parallel to the conveying plane and perpendicularly to the conveying direction and, in the separating position, protruding beyond the conveying plane into the path of the piece goods; and - the bar being rotatable about an axis that is oriented parallel to the conveying plane and perpendicularly to the conveying direction and, in the separating position, blocking a rotation of the stopping claw into the conveying position, characterized in that - the control element is arranged perpendicularly exclusively in and beneath the conveying plane, as seen from the direction of the piece goods; - the pull rod is designed, during the transition from the release position thereof into the blocking position thereof, to slide beneath the bar, and to thereby rotate into the separating position; - the pull rod has a chamfer at the end thereof facing the bar, the chamfer being designed, when sliding beneath the bar, to rotate the bar about the axis thereof upwardly in the direction of the piece goods so as to, in this position, block the stopping claw, which is in the separating position, from pivoting back; and - the pull rod is designed that, when the pull rod is in the release position, the bar is able to rotate back about the axis thereof again, whereby the blockage of the stopping claw is lifted. - the separating device comprising a stop for the piece goods, and a control element; - the control element, as a result of contact with the piece goods occurring in the conveying plane, being rotatable about an axis that is oriented parallel to the conveying plane and perpendicularly to the conveying direction; - a movability of the stop between a separating position and a conveying position, as well as a blockage of the stop in the separating position, being controllable by the control element as a result of the rotation; - the stop being movable by the control element as a result of the rotation; and - the control element being mechanically coupled to the stop by way of a pull rod, the pull rod being movable in and counter to the conveying direction as a result of the rotation, the stop comprising a stopping claw and a bar, - the stopping claw being rotatable about an axis that is oriented parallel to the conveying plane and perpendicularly to the conveying direction and, in the separating position, protruding beyond the conveying plane into the path of the piece goods; and - the bar being rotatable about an axis that is oriented parallel to the conveying plane and perpendicularly to the conveying direction and, in the separating position, blocking a rotation of the stopping claw into the conveying position, characterized in that - the control element is arranged perpendicularly exclusively in and beneath the conveying plane, as seen from the direction of the piece goods; - the pull rod is designed, during the transition from the release position thereof into the blocking position thereof, to slide beneath the bar, and to thereby rotate into the separating position; - the pull rod has a chamfer at the end thereof facing the bar, the chamfer being designed, when sliding beneath the bar, to rotate the bar about the axis thereof upwardly in the direction of the piece goods so as to, in this position, block the stopping claw, which is in the separating position, from pivoting back; and - the pull rod is designed that, when the pull rod is in the release position, the bar is able to rotate back about the axis thereof again, whereby the blockage of the stopping claw is lifted.
