Abstract: A rejection chute for a conveyor system, which receives and redirects rejected parcels, includes: a conduit defined by a plurality of side walls; a door; and an actuator operably connected to the door. The conduit includes an enclosed upper portion defining a first opening for receiving parcels into the rejection chute and a lower portion defining a second opening for discharging parcels from the rejection chute. The door is mounted proximate to the first opening and is configured to transition between a first position to cover the first opening and a second position to uncover the first opening. The rejection chute can be integrated into a walking surface alongside of a conveyor to receive and redirect parcels transferred off of the conveyor to a location below the walking surface. An enclosure can be combined with the rejection chute to regulate access and guide parcels into the rejection chute.

Abstract: A trapdoor rejection subsystem includes one or more trapdoor rejection mechanisms. Each trapdoor rejection mechanism is configured to be selectively transitioned between a closed position to support parcels and an open position to allow parcels identified as unconveyable to pass through the trapdoor rejection mechanism. Each trapdoor rejection mechanism includes a first door, a second door, and one or more actuators which can be selectively actuated to rotate the first door and the second door and transition the trapdoor rejection mechanism between the closed position and the open position. The trapdoor rejection subsystem can be utilized in a conveyor system in combination with one or more robot singulators, an upstream conveyor, a place conveyor, and a vision and control subsystem. Detection of unconveyable parcels and the transition of each trapdoor rejection mechanism of the trapdoor rejection subsystem is controlled by the vision and control subsystem.

Abstract: A system for transferring parcels made in accordance with the present invention includes: a first conveyor for conveying a bulk flow of parcels; a second conveyor positioned adjacent to the first conveyor; a robot positioned adjacent to the first conveyor and the second conveyor; and a rejection member. The robot engages and transfers select parcels in the bulk flow of parcels on the first conveyor to the second conveyor. The rejection member is positioned as to receive parcels offloaded from the first conveyor and/or the second conveyor and directs such parcels out of the system. Parcels within the bulk flow of parcels with characteristics which make it difficult for one or more of the components of the system or downstream systems to handle or process can be directed to the rejection member by operation of the first conveyor and/or the second conveyor to reduce system processing delays and stoppages.
