The invention discloses a tapered roller layered array machine. A plurality of retainer positioning cores are evenly arranged along the circumference of a turntable. A roller array die for enabling rollers to be stored in a ring array shape and fall into a roller retainer roller installing groove according to the ring array shape and a roller array feeding device which sends the rollers one by one into the roller array die in a ring array distribution mode are arranged above the turntable. The roller array die comprises a roller library, a roller lower material-dividing die and a roller dropping die which are arranged from top to bottom. The roller library comprises a roller storage holes which are distributed in a ring array shape and are through up and down. The roller lower material-dividing die is provided with roller lower material-dividing holes which are distributed in a ring array shape and are through up and down. The roller dropping die is provided with roller demolding holes which are distributed in a ring array shape and are through up and down. According to the tapered roller layered array machine, the rollers can be distributed in an array mode and orderly placed on the retainer according to the law, and intelligence and automation are achieved completely.
