Abstract: A transport system and transport device guided via a plurality of rollers in a running direction along a running rail. The transport system has a curved running rail with first and second running surfaces at a first running rail side flank. First and second rollers form a first roller unit for the first running surface, and third and fourth rollers form a second roller unit for the second running surface. The first and/or second roller unit has a rocker unit with a rigid connection of the rotation axles of the first and second rollers of the first roller unit, and/or the rotation axles of the third and fourth rollers of the second roller unit, and a rocker axle. The rigid connection is pivotably supported about the rocker axle, arranged transversely to the running direction of the first and/or second roller unit, which has the rocker unit.

Abstract: A position-detection system for a drive having a rotor, which can move along a path, comprises an encoder unit, a signal-detection unit and a signal-processing device. The encoder unit or the signal-detection unit is arranged on the rotor, and the respective other unit is arranged along the path. Furthermore, the signal-processing device is designed to generate a first position signal and a second position signal on the basis of a relative position of the encoder unit and signal-detection unit. The signal-processing device is designed to determine a longitudinal position of the rotor along the path on the basis of phase values of the first and second position signals. Furthermore, the signal-processing device is designed to determine a distance, directed transversely with respect to the path, between the encoder unit and the signal-detection unit, on the basis of amplitude values of the first and second position signals, and to detect an operating state of the drive on the basis of the distance.

Abstract: The invention relates to a conveying device comprising at least one movable carriage on which at least one first group and at least one second group of track rollers are disposed, and a track rail disposed so as to be locationally fixed for guiding the carriage. The track rail has at least one track face, at least one straight portion and at least one curved portion. The track rollers are configured in such a manner that during movement of the carriage along the straight portion, exclusively the track rollers of the first group roll on the track face assigned to the straight portion, and during movement of the carriage along the curved portion, exclusively the track rollers of the second group roll on the track face assigned to the curved portion. The invention furthermore relates to a further conveying device and corresponding carriages, as described herein.
