A caster wheel alignment system for selectively re-orienting improperly oriented caster wheels for transport vehicles of a conveyor system, such as a circular sorter. The alignment system includes a main support frame couplable with the conveyor at a drive track of the conveyor. The system includes a horizontal cam for adjusting an orientation of the caster wheel from a leading orientation to a trailing orientation. In some forms, the alignment system may include a bypass system, such as a float frame, supporting the horizontal cam, and a vertical cam. The vertical cam provided to temporarily move the float frame and horizontal cam away from the transport vehicle and/or drive track to permit the vehicle to move through the alignment system. The vertical and horizontal cams coordinate to intercept and correct improperly oriented wheels without significantly impeding the movement of the transport vehicle along the drive track.

An object of the present invention is to suppress rise in running resistance with increases in weight of a transport vehicle group, and prevent higher energy consumption and manufacturing cost. A transport device transports a transport vehicle (1) carrying an article (E) along a transport path including a curved path and forms a continuous floor (B) on the transport vehicle (1) in the entire or partial transport path. The transport device includes: running rails (R) that are laid along the transport path to support running wheels (4, 5, and 6) of the transport vehicle (1); guide rails that guide the transport vehicle (1) along the transport path; a drive unit that drives the transport vehicle (1); and a water way (WW) that is formed along the transport path to reserve water (W).

An industrial transportation system includes one or more movers and a robot system. The robot system is configured to load one or more items on the surface of respective movers and unload the one or more items from the surface of respective movers. Each of the one or more movers includes a first surface configured to provide reversible adhesion between the mover and an item loaded on the mover. The reversible adhesion of the surface is activated at loading and deactivated at unloading.
