め使用上の制約があった。Detailed Description of the Invention (Industrial Field of Application) The present invention involves injecting raw materials such as plasticized molten resin into the cavity of a clamped mold, cooling and solidifying the material, and then transferring it between the molds to form a molded product. When applied to injection molding machines, etc. in which the runners are separated and dropped and ejected from a chute, the size of the mesh and the spacing between the rollers should be changed each time the size of the molded product or runner changes due to mold replacement, etc. Because it is difficult to do so, there are restrictions on its use.

ナ仕分装置とした。(Means for Solving the Problem) In order to solve the problem, in the present invention, the molded product and the runner are arranged opposite to the drop opening of the falling chute, and the entire width of the drop opening and a predetermined length further forward are provided. The molded product slips through and falls, but the runner does not fall. A coil spring whose pitch is adjustable is rotatably provided in the direction of pushing up the run, and the runner is rotated against the runner being pushed up. The molded product/runner sorting device is characterized in that a partition plate is provided over the entire length of the coil spring and a predetermined length further forward to prevent movement in the direction and only allow forward transfer.
