  • Patent number: 12280964
    Abstract: A method and device for grouping packages into specified package groups in an interference-free and fault-free manner with a conveyor having multiple individually actuatable conveyors arranged one behind the other with an inlet-side and a discharge-side end. The packages are supplied to the conveyor device at the inlet-side end one after the other, and a control algorithm is carried out to interpolate and/or detect the position and/or the speed of each individual package. A target speed is determined for each individual package based on the detected and/or interpolated position and/or speed of the package. A target speed is determined for the individual conveyors to achieve the target speed for each package to set a specified distance to the leading and/or following package at the discharge-side end. The speed of the individual conveyors is controlled to the respective determined target speed for the conveyor.
