US Patent 11708219 Mobile, rotatable, transport mechanism with multiple conveyor sections

A mobile, rotatable, transport mechanism may include a rotating carrier having a plurality of conveyor sections. The rotating carrier may be moved within a facility by a robotic drive unit. In addition, the rotating carrier may be rotated between a vertical orientation for transport or storage, and a horizontal orientation for transfer of items or trays. A leveling mechanism may maintain the plurality of conveyor sections in a same relative orientation during rotation of the rotating carrier. Further, a height of the rotating carrier and/or angles of the plurality of conveyor sections may be adjusted to facilitate transfer of trays.
