Abstract: The invention relates to a transport system for workpiece carriers along a path, wherein each of a plurality of workpiece carriers has its own drive and energy storage, wherein the drive is effected via a drive means rolling on the guide of the path, said drive means being driven by a motor of the workpiece carrier, wherein at least one absolute value track is attached along the path for position coding of the path and each of a plurality of workpiece carriers has an absolute value sensor, which reads out the absolute value of the absolute value track.

Abstract: The invention concerns a workpiece carrier (4) for a production unit (1) with at least one conveying section (2). The workpiece carrier (4) comprises a workpiece carrier body (13), a workpiece receptacle (16) arranged on the workpiece carrier body (13), a guide device (14) which is arranged on the workpiece carrier body (13) by means of which the workpiece carrier (4) can be received and displaced in the production unit (1), in particular in the conveying section (2), and a code element (20) which is arranged on the workpiece carrier body (13) which is designed to identify the workpiece carrier (4) by means of a detection means (11) arranged in the production unit (1). For identification, the code element (20) has inhomogeneous material properties in its longitudinal orientation.

Abstract: A method positions a first movable unit of a machine system and a second movable unit of the machine system in a definable relative position to each other. For this purpose, the first movable unit is moved to a first position within a first travel space with the aid of a first measuring system. The second movable unit is moved to a second position within a second travel space with the aid of a second measuring system. The first movable unit and/or the second movable unit is moved to the predetermined relative position to each other with the aid of a third measuring system. A machine system carries out the method.

Abstract: The invention describes a turntable (10) with a transfer means (17) for guiding and transmitting a driving force to a parts carrier (1) which can be displaced along guide tracks between a first conveying section (15) and a second conveying section (16) (5), and the transfer means (17) can be pivoted about a pivot axis (19) oriented perpendicular to a transport plane (20). The parts carrier (2) is provided with guide elements (7) by means of which the parts carrier (2) is guided along the guide tracks (5) and the transfer means (17) has a guide track along which the parts carrier (2) is guided by one of the guide elements (7). The invention further relates to a transport system (1) and a method of handling parts carriers (2) by means of a transfer apparatus (14) incorporating the described turntable (10).
