摘要： In a method for tracking packages on a conveyor section, the tracking rate of packages is intended to be maximized. This is achieved by providing a method for tracking packages on a conveyor section, the method comprising the following steps: a) providing a conveyor section having a conveyor surface for conveying a sequence of packages, the conveyor section comprising at least one photoelectric barrier for detecting the packages, b) detecting a photoelectric barrier pattern by means of the photoelectric barrier, the photoelectric barrier pattern being caused by the sequence of packages, c) detecting a conveyor speed of at least one subsection of the conveyor section, d) estimating an event sequence which has with the highest probability caused the photoelectric barrier pattern, while taking into account the conveyor speed of the conveyor section, by means of an algorithm, the algorithm comprising the following further steps: e) compiling a list of possible event sequences, f) sorting the event sequences with the aid of their occurrence probability, g) extending the most probable event sequence by all possible consecutive events, the probability of the event sequence being determined for each extension, h) incorporating the extensions as a new event sequence into the list of event sequences, i) repeating steps g) to h) until the most probable event sequence fully reflects the detected photoelectric barrier pattern.

摘要： A package unit capturing arrangement includes a belt conveyor for transporting a package unit having an identification marking along a conveying direction and includes an optical sensor. The belt conveyor has, parallel to the conveying direction, a sideguard for preventing the packing unit from falling off a belt of the belt conveyor. The sideguard is designed to have a grate in a region. The sensor is arranged laterally with respect to the belt and behind the grate on a side of the sideguard facing away from the belt so that the belt and the grate lie in a field of view of the sensor. A depth of field region of the sensor is narrower than a width of the belt, with the result that the identification marking of the packing unit is optically capturable by the sensor.
