Abstract:
A track-guided transport device for transporting goods, comprising:path means for providing a path of travel, the path means including support and track-guidance elements (16);a transport element (10) to carry the goods, the transport element (10) including a data-processing and information-transmission unit (20), and a regulatable and controllable drive unit (17) for moving the transport element (10) along the path of travel;an energy-transmission device for contactless, inductive transmission of electrical energy to the transport element, the energy-transmission device including a conductor arrangement (6, 7) that is laid along the path of travel and that forms a primary circuit of the energy-transmission device, and a transmitter head (2) that is connected to the transport element, with the transmitter head including a soft-magnetic ferrite core and a secondary winding (W.sub.2) that surrounds the core and is magnetically coupled to the primary circuit; andinformation-transmission means for transmitting information between the transport element (10) and a stationary station, the information-transmission means including a member that is integrated into the conductor arrangement (6, 7) of the energy-transmission device or is integrated into the support and track-guidance elements (16) of the path means,wherein the conductor arrangement (6, 7) of the primary circuit of the energy-transmission device is integrated into the support and track-guidance elements (16), andwherein the primary circuit includes an inside conductor (b) and a U-shaped outside conductor (7) which surrounds the inside conductor coaxially, the outside conductor (7) being connected to the support and track-guidance elements in a conductive manner.
