Method and conveyor belt system with at least one conveyor belt for transporting a flat articles.

摘要

The invention relates to a method for transporting flat transport goods, particularly substrates (3) such as silicon wafers and solar cells, on at least one conveyor belt (2) of a conveyor belt system (1), wherein the substrates (3) are held on a conveying surface (5) of the conveyor belt (2) at least in some cycles during the transport by means of suction. In order to ensure improved slip-resistant and gentle transport of the substrates (3) on the conveyor belt (2), according to the invention along at least one of the two longitudinal edges (7) of the strap (8) of the conveyor belt (2) that extend in the transport direction, in a plurality of positions (9) spaced with respect to each other, underpressure that is based on the Bernoulli effect is generated by means of a guidance of a pressure medium (11), such as compressed air, that is controlled by a flow system (4), and, as a result of the pressure difference between the atmospheric pressure and the underpressure generated at the respective position (9) formed at the respective position (9) on the longitudinal edge of the belt, the substrates (3) are held with uniform pressure on the transport surface (5) of the conveyor belt (2) with the contact surface.
