Patent attributes
Disclosed herein is a circulation conveyor transport wheel that includes a framework at which the circulation conveyor transport wheel can be rotatably mounted and a multiplicity of coupling devices which are arranged at an outer circumference of the framework, wherein each coupling device has at least one form-fit contour for form-fitting coupling to a substrate carrier. The substrate carrier includes multiple members which are connected to one another by a rotary connection, two carriages which are arranged on mutually opposite sides of the substrate carrier to guide the substrate carrier along a transport path, and multiple coupling devices (as counterparts to the coupling device on the transport wheel), each of which comprises at least one form-fit contour arranged between the two carriages, wherein two form-fit contours are offset with respect to one another along the transport path of the substrate carrier.
