Abstract
An apparatus for conveying objects includes a conveyor belt. A belt core material of the conveyor belt comprises rigid thread elements. Apertures for communicating the inner and outer surfaces of the belt core material are partly blocked by a plurality of annular seal strips each of which is continuous in a belt moving direction. The objects are seated over adjacent seal strips spaced apart from each other. The objects are conveyed while being drawn by a negative pressure, produced by a suction unit and introduced from the inner surface side of the conveyor belt through the apertures. During the conveyance, the objects are inspected. The objects supplied at optional intervals are stabilized with a constant suction force and conveyed. Thereafter, the objects are reliably turned over and transferred to another conveyor apparatus of the next stage.
