Method for transferring a workpiece carrier between two toothed-belt conveyors

The invention relates to a method for transferring a workpiece carrier (5) in a manufacturing facility (1) from a first conveying portion (2), which is controlled by a first controller (26), to a second conveying portion (3), which is controlled by a second controller (27), the conveying portions (2, 3) each comprising a toothed belt (9, 10). On the basis of an internal timer (28, 29) in the two controllers (26, 27), a desired position of a virtual tooth space (37) in the transfer region (16) of the conveying portions (2, 3) is calculated, taking the predefined movement speed of the workpiece carrier (5) into consideration and taking the tooth pitch (15) of the toothed belts (9, 10) into consideration, the toothed belts (9; 10) being controlled and synchronized by the respective controller (26, 27) via the drive units (11, 12) such that a first tooth space (17) of the first toothed belt (9) and a second tooth space (18) of the second toothed belt (10) are synchronized with the desired position of the virtual tooth space (37).
