  • Publication number: 20170320677
    Abstract: A method for combining multiple separate streams of packaged materials into a main stream is provided, in which each of the streams of packaged materials is conveyed on a feed conveyor, is combined with the main stream in the region of a feed opening of the feed conveyor and further transported on a main conveyor in the main stream and in which at least one lateral wall laterally delimits the main stream. In order to combine multiple separate streams of packaged materials into the main stream despite a narrowing of the conveyor width to counteract jamming, packaged materials from the main stream in the region between two feed openings of two feed conveyors are guided towards the lateral wall and then along the lateral wall, as a result of an alignment of the main conveyor relative to the lateral wall. A device for conveying packaged materials is also provided.

  • Patent number: 9517492
    Abstract: A transporting device transports objects in a transport direction from a loading region to an unloading region. The device includes a first conveying unit and a second conveying unit which are arranged one behind the other in the transport direction. Efficient unloading of the objects from the transporting device is achieved by providing a separating device between the first and second conveying units. The separating device is configured to separate the objects into at least two object groups dependent on at least one object property.

  • Patent number: 6776277
    Abstract: The invention relates to a conveyor device for transporting and expelling material to be conveyed, especially flat postal items. The inventive device comprises vertically pivotable conveying modules that are arranged one behind the other. The aim of the invention is to reduce the closing time required by the pivoted conveyor module component to go back to the level of the succeeding conveyor module component. The component of the conveyor modules is designed in such a way that said component can also be driven in the vertical direction, whereby said component is the front component when seen in the conveying direction. Immediately after a material to be conveyed (3) has been expelled and when the next material to be conveyed (3) is transported further, said front component of the conveyor module (1) that succeeds the expelling conveyor module (1) is pivoted against the component that is pivoted for expelling.
