PROBLEM TO BE SOLVED: To provide a polishing and lifting/feeding device that can prevent game balls in a lifting/feeding duct from falling when the duct is removed, and can also prevent game balls from reversely flowing in the lifting/feeding duct when the conveyance belt is stopped.SOLUTION: A polishing and lifting/feeding device 9 includes: an endless conveyor belt 10; a polishing cloth 11 for wiping off stains on the surface of game balls; and a lifting/feeding duct 18 for lifting/feeding game balls flown out from the conveyance surface of the conveyor belt 10. To the game balls having entered between the conveyance surface of the conveyor belt 10 and the polishing cloth 11, lifting/feeding force in the lifting/feeding duct 18 is applied when the conveyor belt 10 is turned while wiping off stains on the surface with the polishing cloth 11. In a lower end of the lifting/feeding duct 18, a lifting/feeding duct-side reverse flow prevention means 19 is provided to prevent game balls from reversely flowing. |
