Transfer device for transferring solid articles

摘要

A transfer device for transferring solid articles, comprising: a cylindrical member which has a supply opening formed at one end portion and a discharge opening formed at the other end portion, such that an angle formed between an axis of the cylindrical member and a horizontal plane is not more than 75 DEG ; a transfer member which is rotatably provided in the cylindrical member; the transfer member including a rotary shaft extending along the axis of the cylindrical member and a helical vane projecting from a peripheral surface of the rotary shaft such that lead angle of the helical vane at its outer peripheral edge ranges from 3 DEG to 25 DEG ; and a drive member so as to rotate the transfer member about the axis of the cylindrical member at a rotational speed of not more than 500 r.p.m.
