A goods transfer station for discharging articles, comprising:

• at least one partition wall with at least one delivery window,
• a rotatable rotary body having an axis and a lateral surface area which is continuous except at at least one opening, and
• at least one linear transfer channel arranged in said rotary body, said transfer channel comprising at least one conveying space arranged in said rotary body and at least one closing element, wherein
• the at least one conveying space is closed except for said at least one opening, through which an article can be discharged from the conveying space,
• the at least one conveying space can be moved between at least one unloading position and at least one loading position by rotation of the rotary body,
• the at least one opening is located in the delivery window in the unloading position,
• the at least one opening can be closed by the closing element at least in the unloading position,
• the transfer channel comprises at least one piston element having a side directed toward the opening, the side acting as the closing element,
• the at least one piston element is arranged linearly movable in the transfer channel in a plane perpendicular to the axis of the rotary body,
• the side of the at least one piston element, which acts as the closing element, has a curvature adapted to a shape of the rotary body in order to close the opening in the lateral surface of the rotary body after discharging the article from the conveying space and before and while rotating the opening away from the unloading position.
