Abstract
The present invention relates to a method and apparatus for conveying articles, particularly sheet stacks, the articles (5, 105) being conveyed in a common direction on a connecting conveyor (2) and an accumulating conveyor (3) overlapping with the latter and following articles (5) are connected to previously conveyed articles (105) in accordance with different speeds of the two conveyors. The method or apparatus is characterized in that, at least in the overlap area, the articles are sucked by a suction air device (42) onto the connecting conveyor and/or accumulating conveyor. Preferably the articles are also subject to air blast action in the overlap area of the two conveyors.
Claims23
Method for conveying articles, particularly sheet stacks, comprising the steps of:
- conveying the articles on a connecting conveyer and an accumulating conveyor overlapping with the connecting conveyor in an overlap area in a common direction, at least one of said conveyors associated with associated fluid chambers;
- connecting each said fluid chambers to a suction air unit and an air blast source;
- connecting following articles to previously conveyed articles at an accumulation point corresponding to different speeds of the connecting conveyor and the accumulating conveyor;
- and,
- sucking the articles by means of suction air onto at least one of the connecting conveyor and the accumulating conveyor at least in the overlap area.
Conveying apparatus for conveying articles, particularly sheet stacks, said apparatus comprising:
- a connecting conveyor;
- an accumulating conveyor, said conveyors having a common conveying direction and overlap one another in an overlap area and can be operated at different speeds, at least one of said conveyors associated with associated fluid chambers, each fluid chamber connectable to a suction air unit and an air blast source;
- and, a suction device for sucking the articles onto at least one of the connecting conveyor and the accumulating conveyor in the overlap area thereof.
