Abstract

The present invention discloses an automated waste sorter ( 100 ) for sorting/segregating one or more categories of materials from a mixed waste stream. The automated waste sorter ( 100 ) includes a primary conveyor belt ( 110 ), an encoder ( 170 ), one or more sensors ( 131 ), a vision system ( 130 ) and an ejection means ( 150 ). The primary conveyor belt ( 110 ) moves the mixed waste stream at a predefined speed. The vision system ( 130 ) is trained to analyze the frame to identify, classify and locate one or more classified waste material using at least one of a plurality of identity parameters and/or a plurality of other parameters. The ejection means ( 150 ) includes one or more manifolds to eject the one or more classified waste material based on the one or more coordinates communicated by the vision system ( 130 ). A method to operate the automated waste sorter ( 100 ) is also disclosed.

Claims (18)

1 . An automated waste sorter ( 100 ) for sorting/segregating one or more categories of materials from a mixed waste stream, comprising:

a primary conveyor belt ( 110 ) to move the mixed waste stream at a predefined speed;

an encoder ( 170 ) operationally coupled to the primary conveyor belt ( 110 ) to detect the predefined speed of the primary conveyor belt ( 110 );

one or more sensors ( 131 ) to capture a predefined area ( 131 a ) of the primary conveyor belt ( 110 ) in a frame based on inputs of the encoder ( 170 );

a vision system ( 130 ) operationally coupled to the one or more sensors ( 131 ), the encoder ( 170 ) and the primary conveyor belt ( 110 ), the vision system ( 130 ) being trained to analyze the frame to identify, classify and locate from the mixed waste stream, waste material using at least one of a plurality of identity parameters and/or a plurality of other parameters, the vision system ( 130 ) being further configured to determine one or more coordinates that correlate with a location of the classified waste material on the primary conveyor belt ( 110 ); and

an ejection means ( 150 ) including one or more manifolds to eject the one or more classified waste material based on the one or more coordinates communicated by the vision system ( 130 ), each of the manifolds having a plurality of pneumatic valves;

wherein, at least one of the plurality of pneumatic valves is configured to automatically change, by the one or more manifolds, a pre-defined angle of the at least one of the plurality of pneumatic valves based on a predefined trajectory and the one or more coordinates and produce a plurality of controlled bursts of air towards the classified waste material, wherein the at least one pneumatic valve is configured to one or more of:

release the plurality of controlled bursts of air at a center of an area of the classified waste material;

release the plurality of controlled bursts of air at a flow rate corresponding to a preconfigured amount for each classifier of the classified waste material; or

release the plurality of controlled bursts of air at a flow rate corresponding to at least one of: the area or weight of the classified waste material, thereby, accurately ejecting the classified waste material from the primary conveyor belt ( 110 ) to a predefined destination/bin.

2 . An automated waste sorter ( 100 ) for sorting/segregating one or more categories of materials from a mixed waste stream, comprising:

a primary conveyor belt ( 110 ) to move the mixed waste stream at a predefined speed;

an encoder ( 170 ) operationally coupled to the primary conveyor belt ( 110 ) to detect the predefined speed of the primary conveyor belt ( 110 );

one or more sensors ( 131 ) to capture a predefined area ( 131 a ) of the primary conveyor belt ( 110 ) in a frame based on inputs of the encoder ( 170 );

a vision system ( 130 ) operationally coupled to the one or more sensors ( 131 ), the encoder ( 170 ) and the primary conveyor belt ( 110 ), the vision system ( 130 ) being trained to analyze the frame to identify, classify and locate from the mixed waste stream, waste material using at least one of a plurality of identity parameters and/or a plurality of other parameters, the vision system ( 130 ) being further configured to determine one or more coordinates that correlate with a location of the classified waste material on the primary conveyor belt ( 110 ); and

an ejection means ( 150 ) including one or more manifolds to eject the one or more classified waste material based on the one or more coordinates communicated by the vision system ( 130 ), each of the manifolds having a plurality of pneumatic valves;

wherein, at least one of the plurality of pneumatic valves is configured to automatically change, by the one or more manifolds, a pre-defined angle of the at least one of the plurality of pneumatic valves based on a predefined trajectory and the one or more coordinates and produce a plurality of controlled bursts of air towards the classified waste material,

wherein a duration of each of the plurality of controlled bursts of air is changed in real-time based upon weight of the classified waste material, thereby, accurately ejecting the classified waste material from the primary conveyor belt ( 110 ) to a predefined destination/bin.
