A molded product take-out apparatus includes: a controller independent of a molding machine; a take-out robot for releases a molded product from a mold in the molding machine by a command from the controller; a temperature controller regulates the temperature of the mold; a material dryer dries material to be supplied to the molding machine; and a material conveyor supplies the dried material to the molding machine. The controller is network-connected to the take-out robot and the temperature controller and the material dryer and the material conveyor. The controller is configured to control a release operation of the take-out robot to differentiate a release place between when judging that a detection data to be within an allowable range and another case.

A virgin material plasticization time Tv, which is a time required for a screw to reach a predetermined plasticization end position Xe when only a virgin material Rv is plasticized, a crushed material plasticization time Ts, which is a time required for the screw to reach the predetermined plasticization end position Xe when only a crushed material Rs is plasticized, are measured and registered as basic time data Do. Actually measured time data Dp are obtained by measuring a crushed material mixed material plasticization time Tm when a molded product is produced by using the crushed material mixed material Rm, the crushed material mixed material plasticization time Tm being a time required for the screw to reach the plasticization end position Xe in a predetermined shot. The crushed material ratio Px in the crushed material mixed material Rm is obtained on the basis of the virgin material plasticization time Tv, the crushed material plasticization time Ts, and the crushed material mixed material plasticization time Tm. An output process is performed on the obtained crushed material ratio Px.
