Abstract
A device for counting the number of and determining the direction of travel of articles being conveyed, particularly articles of clothing, hanging on hangers provided with hanger hooks. Each hanger hook has a stem that is conducted through a light barrier connected with a counting and evaluating unit. The light barrier has at least two receivers that are spaced apart vertically in a plane and consist, in each case, of two sensors which operate independent of each other. The sensors are separated by a small distance. With this device, counting of the hangers is possible regardless of their position and, in particular, erroneous counting due to crossed hangers is excluded.
