Abstract

The conveyor sorting system and method are provided. The system includes a conveyor for transporting articles along a predetermined path, and a pair of opposing chutes for receiving articles directed from the conveyor by a sorting device having a single paddle. The chutes are in communication with one another so that articles directed into either chute from the conveyor are directed to a common discharge end. In this regard, the single paddle of the present invention is operable to direct consecutively-spaced articles to opposing chutes that lead to the common discharge end.

Claims

1. A sorting system for sorting articles of different types, the system comprising:

a conveyor for transporting the articles along a path of travel, said conveyor defining a pair of opposing sides;

a detector positioned proximate said conveyor for detecting the presence of the articles;

a pair of opposing chutes defining inlets adjacent said opposing sides of said conveyor; and

at least one paddle having a first side and a second side, said paddle being in operative communication with said detector such that both of said sides of said paddle are operable to engage articles and direct articles into either inlet of said pair of opposing chutes, wherein said pair of opposing chutes further defines outlet in communication with one another that combine and define a common discharge end.

2. A sorting system according to claim 1, further comprising a drive source operably connected to said at least one paddle for directing said at least one paddle into engagement with the article being transported by the conveyor.

3. A sorting system according to claim 2, wherein said drive source is a pneumatic drive source.

4. A sorting system according to claim 2, wherein said drive source is a hydraulic drive source.

5. A sorting system according to claim 2, wherein said drive source is an electric drive source.

6. A sorting system according to claim 1, wherein at least one of said first side and said second side of said paddle has a surface complimentary to the articles.

7. A sorting system according to claim 1, wherein said at least one paddle includes a brush at one end thereof.

8. A sorting system according to claim 1, wherein said conveyor includes an external surface having a plurality of raised portions extending therefrom.

9. A sorting system according to claim 1, further comprising a cover layer attached to at least one of said pair of opposing chutes.

10. A sorting system according to claim 9, wherein said cover layer extends over at least a portion of said at least one of said pair of opposing chutes.

11. A sorting system for sorting articles of different types, the system comprising:

a conveyor for transporting the articles along a path of travel, said conveyor defining a pair of opposing sides;

a pair of chutes defining inlets adjacent said opposing sides of said conveyor;

a discharge wall movably attached to at least one of said pair of opposing chutes, said discharge wall movable at least between a discharge position and a storage position; and

at least one paddle having a first side and a second side, said paddle being operable to engage articles and direct articles into either inlet of said pair of opposing chutes.

12. A sorting system according to claim 11, further comprising an actuator operable to move said discharge wall between the discharge position and the storage position.

13. A sorting system according to claim 11, wherein said pair of opposing chutes further defines outlets in communication with one another that combine and define a common discharge end.

14. A sorting system according to claim 11, wherein said at least one paddle includes a brush at one end thereof.

15. A sorting system according to claim 11, wherein said conveyor includes an external surface having a plurality of raised portions extending therefrom.
