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.

Trapdoor rejection subsystem for a conveyor system

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.

Rejection chute for a conveyor system

In an extendible belt conveyor with a boom mounted for movement with respect to a penultimate section and a cable extending from user controls on the boom to the penultimate section, a cable management system may include a first pulley mounted to an underside of the penultimate section and a second pulley mounted to the underside of the penultimate section, with a distance between the first pulley and the second pulley adjusted to maintain tension in the cable. The cable management system may also include a first shoe mounted to an underside of the boom near the penultimate section and a second shoe mounted to the underside of the penultimate section near the boom. The first shoe defines a channel for receiving the cable and the second shoe defines a channel for receiving the cable, with the cable passing around the first shoe and then around the second shoe.

Extendible belt conveyor and cable management system for same

An extendible belt conveyor includes a penultimate section, a boom mounted for pivotal movement with respect to the penultimate section, and a transfer plate spanning between the belt of the boom and the belt of the penultimate section. The transfer plate includes a plurality of first components and a plurality of second components that each include a base member mounted on and rotatable with respect to a rod, and a flange member extending from the base member and positioned adjacent to one of the belts of the boom or penultimate section, with a distal edge of the flange member extending over the belt. As the boom pivots, an upper surface of the plurality of first components remains substantially parallel to the belt of the boom, and an upper surface of the plurality of second components remains substantially parallel to the belt of the penultimate section.
