| 摘要 |
The invention relates to a method for positioning plate elements (10) inside a treatment machine (1) including a introducer (20) for positioning said plate elements (10) in a plurality of gripping members (31) of a conveyor (30) that conveys said elements into successive stations (3, 4, 5) in a rhythmic movement, said introducer (20) being provided with an attachment device (21), said introducer (20) being controlled by a computing and control unit (40). The method includes the successive steps comprising, during the forward movement of each plate element (10): measuring the longitudinal positioning error and the angular positioning error of the plate element (10) relative to a theoretical position, by detecting the leading edge or the tail edge of the plate element (10); controlling the introducer (20) according to the longitudinal positioning error and the angular positioning error measured; activating the attachment device (21) to secure said plate element (10) to the introducer (20); measuring the longitudinal positioning error, the transverse positioning error and the angular positioning error of the plate element (10) secured to the introducer (20), relative to a theoretical position, by detecting reference marks (12) printed on said plate element (10).
