Abstract
A method for transferring a workpiece carrier in a manufacturing facility from a first conveying portion, which is controlled by a first controller, to a second conveying portion, which is controlled by a second controller is provided. The conveying portions each have a toothed belt. On the basis of an internal timer in the two controllers, a desired position of a virtual tooth space in the transfer region of the conveying portions is calculated, taking the predefined movement speed of the workpiece carrier into consideration and taking the tooth pitch of the toothed belts into consideration. The toothed belts are controlled and synchronized by the respective controller via the drive units such that a first tooth space of the first toothed belt and a second tooth space of the second toothed belt are synchronized with the desired position of the virtual tooth space.
