Abstract (en)

[origin: WO2021213990A1] The invention relates to a method for individualizing plates, having the following steps: continuously conveying a sheet metal strip (2) in a transport direction (T) to a laser cutting station (3), concurrently cutting the sheet metal strip (2) using at least one cutting laser, wherein a cut sheet metal strip (2) is made from successive sections (AT) with the same cut geometry, and each section (AT) comprises at least one plate (P) and at least one scrap plate (RP) adjoining the plate (P), transporting the cut sheet metal strip (2) on a first transport belt (4) in the transport direction (T), transferring the cut sheet metal strip (2) from the first transport belt (4) using a suction conveyor (5) which is operated using negative pressure, transporting the cut sheet metal strip (2) in the transport direction (T) in a suspended manner using the suction conveyor (5), separately dropping the at least one scrap plate (RP) of each section (AT) by interrupting the negative pressure a first time in specified regions of the suction conveyor (5), transporting the at least one plate (P) of each section (AT) so as to overlap with a second transport belt (6) and dropping the at least one plate (P) from the suction conveyor (5) by interrupting the negative pressure a second time, and horizontally transporting the plates (P) dropped one after the other by the suction conveyor to a collection station (7) in the transport direction (T).
