Abstract:
An article conveying device comprising:a rotational conveying mechanism which causes a rotational conveyance of a plurality of artcle holding members, which are disposed at equal intervals, in one direction along a ring-form-track that has a pair of parallel sections, and a reciprocating driving mechanism which causes said rotational conveying mechanism as a whole to perform a reciprocating movement for a specified distance along said parallel sections; and wherein said rotational conveying mechanism and reciprocating driving mechanic are respectively provided with their own driving sources, said driving sources of said rotational conveying mechanism and reciprocating driving mechanism are independent servo motors, said article holding members have a moving speed that is obtained by synthesizing said rotational conveyance and said reciprocating movement so that said article holding members are moved intermittently a specified distance, that is equal to an integral multiple of an attachment spacing of said plurality of article holding members, on a first side of said parallel sections and are moved continuously at a constant speed on a second side of said parallel sections, and a rotational conveying speed of said plurality of article holding members is set so as to be different in an advancing direction and a return direction of said rotational conveying mechanism.
