Abstract

Systems, apparatuses, and methods are provided herein for sorting items discarded in a shopping facility. A system for sorting discarded items comprises a motorized transport unit configured to travel around discarded items placed in a sorting area in the shopping facility, the motorized transport unit comprises a sensor device and an item mover device, an item characterization database storing characteristics corresponding to a plurality of items likely to be found in the shopping facility, and a central computer system. The central computer system is configured to receive data from the sensor device on the motorized transport unit, determine an item characteristic of an item among the discarded items in the sorting area, determine a sorting category of the item from a plurality of predefined categories, and cause the motorized transport unit to move the item, with the item mover device, from the sorting area into a category area.

First claim

What is claimed is:

1. A system for sorting items discarded in a shopping facility, comprising:
a motorized transport unit configured to travel around discarded items collected from the shopping facility and placed in a sorting area in the shopping facility, the motorized transport unit comprises a sensor device and an item mover device;
an item characterization database storing characteristics corresponding to a plurality of items likely to be found in the shopping facility; and
a central computer system coupled to the motorized transport unit and the item characterization database, and configured to:
receive data from the sensor device on the motorized transport unit;
determine an item characteristic of an item among the discarded items in the sorting area based on the data from the sensor device;
determine a sorting category of the item from a plurality of predefined categories based on the item characterization database, each of the plurality of predefined categories corresponds to a method of discarded item deposition; and
cause the motorized transport unit to move the item, with the item mover device, from the sorting area into a category area associated with the sorting category.

2. The system of claim 1 , wherein the plurality of predefined categories comprises one or more: recyclable items, compostable items, likely customer items, merchandise, merchandise-like items, valuable items, metal items, glass items, paper items, plastic items, and trash.

3. The system of claim 1 , wherein the sensor device comprises one or more of an image sensor, a weight sensor, a barcode reader, and a radio frequency identification (RFID) reader.

4. The system of claim 1 , wherein the item characteristic comprises one or more of: item appearance, item shape, item weight, item density, item text, item identifier, item barcode, and item condition.

5. The system of claim 1 , wherein the item characterization database comprises a plurality of object models, and the item characteristic is determined based on comparing the data received from the sensor device with the plurality of object models in the item characterization database.

6. The system of claim 1 , wherein the item characteristic is determined by comparing an item identifier associated with the item with a store inventory database to determine whether the item corresponds to merchandise sold in the shopping facility.

7. The system of claim 1 , further comprising a separator configured to receive the discarded items from a container and loosen the discarded items from each other prior to the discarded items being placed in the sorting area.

8. The system of claim 1 , further comprising a tumbler configured to separate the discarded items by size prior to the discarded items being placed in the sorting area.

9. The system of claim 1 , further comprising a fan configured to remove light weight material from the discarded items.

10. The system of claim 1 , wherein the sorting area comprises a sorting platform and the category area comprises one of a plurality of receptacle bins positioned adjacent to the sorting platform.

11. A method for sorting items discarded in a shopping facility, comprising:
receiving, at a control circuit, data from a sensor device on a motorized transport unit configured to travel around discarded items collected from the shopping facility and placed in a sorting area in the shopping facility;
determining, by the control circuit, an item characteristic of an item among the discarded items in the sorting area based on the data from the sensor device;
determining, by the control circuit, a sorting category of the item from a plurality of predefined categories based on an item characterization database storing characteristics corresponding to a plurality of items likely to be found in the shopping facility, wherein each of the plurality of predefined categories corresponds to a method of discarded item deposition; and
causing the motorized transport unit to move the item from the sorting area into a category area associated with the sorting category with an item mover device of the motorized transport unit.

12. The method of claim 11 , wherein the plurality of predefined categories comprises one or more: recyclable items, compostable items, likely customer items, merchandise, merchandise-like items, valuable items, metal items, glass items, paper items, plastic items, and trash.

13. The method of claim 11 , wherein the sensor device comprises one or more of an image sensor, a weight sensor, a barcode reader, and a radio frequency identification (RFID) reader.

14. The method of claim 11 , wherein the item characteristic comprises one or more of: item appearance, item shape, item weight, item density, item text, item identifier, item barcode, and item condition.

15. The method of claim 11 , wherein the item characterization database comprises a plurality of object models, and the item characteristic is determined based on comparing the data received from the sensor device with the plurality of object models in the item characterization database.

16. The method of claim 11 , wherein the item characteristic is determined by comparing an item identifier associated with the item with a store inventory database to determine whether the item corresponds to merchandise sold in the shopping facility.

17. The method of claim 11 , further comprising: causing a separator configured to receive the discarded items from a container to loosen the discarded items from each other prior to the discarded items being placed in the sorting area.

18. The method of claim 11 , further comprising: causing a tumbler to separate the discarded items by size prior to the discarded items being placed in the sorting area.

19. The method of claim 11 , further comprising: causing a fan to remove light weight material from the discarded items.

20. The method of claim 11 , wherein the sorting area comprises a sorting platform and the category area comprises one of a plurality of receptacle bins positioned adjacent to the sorting platform.

21. An apparatus for sorting items discarded in a shopping facility comprising:
a non-transitory storage medium storing a set of computer readable instructions; and
a control circuit configured to execute the set of computer readable instructions which causes to the control circuit to:
receive, at a control circuit, data from a sensor device on a motorized transport unit configured to travel among discarded items collected from the shopping facility and placed in a sorting area in the shopping facility;
determine, by the control circuit, an item characteristic of an item among the discarded items in the sorting area based on the data from the sensor device;
determine, by the control circuit, a sorting category of the item from a plurality of predefined categories based on an item characterization database storing characteristics corresponding to a plurality of items likely to be found in the shopping facility, each of the plurality of predefined categories corresponds to a method of discarded item deposition; and
cause the motorized transport unit to move the item from the sorting area into a category area associated with the sorting category with an item mover device of the motorized transport unit.
