ABSTRACT:
The device of this invention comprises a drum 11 rotatably mounted on a mounting frame 10. The device is designed to receive articles to be sorted from a controlled feed conveyor 12. The rotating drum 11, through its internal structure including lift fins 16 and associate structure, position the oblong articles on counter-rotating shaft conveyor 13. The articles proceed down the counter-rotating shaft conveyor 13 to a chain link loading mechanism 36 placing the sorted articles in receiving slots on chain link conveyor 37. Incorporated in the invention of this device are control structures such as feed control tilt flaps 20 and their associated structure which controls the rate of supply of articles to the rotating drum 11 by feed conveyor 12 and return rejected articles to the rear of the drum. A detector 29 is incorporated in association with the counter-rotating shaft conveyor 13 and include shaft conveyor light source 30, the shaft conveyor electric eye 31, and clearing means 32. Articles received from counter-rotating shaft conveyor 13 are positioned on the chain link conveyor by chain link loading mechanism 36. The device of this invention is normally designed to operate in conjunction with an automatic wrapping mechanism which is fed by chain link conveyor 37.
