Rejection chute 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.
1. A conveyor system, comprising:
a conveyor with a conveying surface for carrying a bulk flow of parcels; and
a rejection chute positioned adjacent to the conveyor, the rejection chute including
a conduit defined by a plurality of side walls, the conduit including an enclosed upper portion defining a first opening for receiving parcels from the conveyor into the rejection chute and a lower portion defining a second opening for discharging parcels from the rejection chute,
a door mounted proximate to the first opening, the door being configured to transition between a first position to cover the first opening and a second position to uncover the first opening, and
an actuator operably connected to the door and configured to transition the door between the first position and the second position;
wherein the rejection chute is positioned relative to a walking surface, which extends alongside the conveyor in a plane below the conveying surface of the conveyor; and
wherein the door is positioned in substantially the same plane as the walking surface, below the conveying surface of the conveyor, when the door is in the first position, and such that parcels discharged from the rejection chute are discharged below the walking surface.
2. The conveyor system as recited in claim 1 , wherein at least one side wall of the plurality of side walls defining the conduit curves as the side wall extends from the enclosed upper portion of the conduit to the lower portion of the conduit to discharge parcels from the rejection chute in a direction substantially perpendicular to the direction in which the parcels are initially received into the rejection chute.
3. The conveyor system as recited in claim 1 , wherein the door is mounted to a shaft, the shaft being operably connected to the actuator and defining an axis of rotation about which the door can rotate to transition between the first position and the second position.
4. The conveyor system as recited in claim 3 , and further comprising:
a linkage assembly interconnecting the actuator and the shaft, the linkage assembly including
a first linkage having a proximal end connected to a distal end of an arm of the actuator, and
a second linkage having a proximal end pivotally connected to a distal end of the first linkage and a distal end connected to the shaft.
5. The conveyor system of claim 1 , wherein the lower portion of the conduit is partially enclosed.
6. A conveyor system, comprising:
a conveyor for carrying a bulk flow of parcels;
a rejection chute positioned adjacent to the conveyor, the rejection chute including
a conduit defined by a plurality of side walls, the conduit including an enclosed upper portion defining a first opening for receiving parcels from the conveyor into the rejection chute and a lower portion defining a second opening for discharging parcels from the rejection chute,
a door mounted proximate to the first opening, the door being configured to transition between a first position to cover the first opening and a second position to uncover the first opening, and
an actuator operably connected to the door and configured to transition the door between the first position and the second position;
wherein the rejection chute is positioned relative to a walking surface extending alongside the conveyor, such that the door is positioned in substantially the same plane as the walking surface when the door is in the first position, and such that parcels discharged from the rejection chute are discharged below the walking surface;
an enclosure positioned on top of the rejection chute, the enclosure including
a pair of side walls spaced apart from one another and extending substantially parallel to the conveyor,
a first gate positioned at a first end of the enclosure between the pair of side walls of the enclosure, wherein the first gate is pivotally mounted to one of the pair of side walls, such that the first gate pivots about a substantially vertical axis between an open position providing access to a pathway over the door of the rejection chute and a closed position restricting access to the rejection chute, and
a second gate positioned at a second end of the enclosure between the pair of side walls of the enclosure, wherein the second gate is pivotally mounted to one of the pair of side walls, such that the second gate pivots about a substantially vertical axis between an open position providing access to the rejection chute and a closed position restricting access to the rejection chute.
7. An assembly for use with a conveyor system, comprising:
a rejection chute, the rejection chute including
a conduit defined by a plurality of side walls, the conduit including 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 the parcels from the rejection chute,
a door mounted proximate to the first opening of the conduit, the door being configured to transition between a first position to cover the first opening and a second position to uncover the first opening, and
an actuator operably connected to the door and configured to transition the door between the first position and the second position; and
an enclosure positioned on top of the rejection chute, the enclosure including
a pair of side walls spaced apart from one another and extending in parallel,
a first gate positioned at a first end of the enclosure between the pair of side walls of the enclosure, wherein the first gate is pivotally mounted to one of the pair of side walls, such that the first gate pivots about a substantially vertical axis between an open position
a second gate positioned at a second end of the enclosure between the pair of side walls of the enclosure, wherein the second gate is pivotally mounted to one of the pair of side walls, such that the second gate pivots about a substantially vertical axis between an open position providing access to the pathway over the door of the rejection chute and a closed position restricting access to the rejection chute.
8. The assembly as recited in claim 7 , wherein at least one side wall of the plurality of side walls defining the conduit curves as the side wall extends from the enclosed upper portion of the conduit to the lower portion of the conduit to discharge parcels from the rejection chute in a direction substantially perpendicular to the direction in which the parcels are initially received into the rejection chute.
9. The assembly as recited in claim 7 , wherein the door is mounted to a shaft, the shaft being operably connected to the actuator and defining an axis of rotation about which the door can rotate to transition between the first position and the second position.
10. The assembly as recited in claim 9 , wherein the rejection chute further includes a linkage assembly interconnecting the actuator and the shaft, the linkage assembly including:
a first linkage having a proximal end connected to a distal end of an arm of the actuator; and
a second linkage having a proximal end pivotally connected to a distal end of the first linkage and a distal end connected to the shaft.
