Abstract: In a board transfer method, a board (1) prior to component placement thereon is transferred from a loader unit (15) into a component-placement position and, after the component placement is carried out, the board (1) is returned to the loader unit (15) and discharged therefrom. After the placement of components onto the board (1) in the component-placement position, the board (1) is moved from the component-placement position onto an unloader unit (9), while simultaneously transferring a succeeding board prior to component placement thereon from the loader unit (15) into the component placement position. Thereafter the unloader unit (9) is moved above the board that is in the component-placement position until the unloader unit (9) is coupled with the loader unit (15), and then the board that has been moved to the unloader unit (9), is delivered to the loader unit (15) and then discharged therefrom.

Abstract: A component feed apparatus includes a first feed table (9, 9a) loaded with a plurality of component feed cassettes (1) thereon and moving in a manner so that the first feed table can be positioned in a right-left direction as an arrangement direction of the component feed cassettes. A second feed table (10, 10a) is located at the rear of the first feed table and is loaded and arranged with a plurality of component feed cassettes (1) in the right-left direction. Also, a component transfer unit (8) which is located at the lateral side of the first feed table and moves so that the component transfer unit can be positioned in the right-left direction, thereby receiving components from the component feed cassettes on the second feed table and sending the components forward.

Abstract: Provided is a plurality of component supply units (A, B, C) having a component supply table (11) mounted with a plurality of component supply cassettes (1), a rail (12) which reciprocatingly movably guides and supports the component supply table, a base (22) which fixes the rail, a driving member (14) which moves in a direction in which a component determining table moves while being able to be positioned in the base, and a coupling member (13f, 13c, 13r, 16) which can releasably couple the component determining table with the driving member.

Abstract: A component feeding device (1) comprises a first feeder table (7) provided with a plurality of component supply units (6) aligned in parallel rows thereon, and arranged for movement in a direction of the parallel alignment, a second feeder table (8) provided with a plurality of component supply units (6) aligned in parallel rows thereon, and located behind the first feeder table (7), and a transfer unit (9) for receiving and conveying supplementary components from the component supply units (6) on the second feeder table (8) to a predetermined component feeding position. When a certain group of the components on the first feeder table (7) has been exhausted, their new supplies are picked up from the second feeder table (8) by the transfer unit (9), conveyed to the component feeding position, and placed on a board (5), thereby eliminating necessity for providing waiting spaces for feeder tables (7, 8) in a flow direction of boards (5) and increasing productivity with a compact arrangement.

Abstract: An apparatus for supplying headed parts from a hopper to a chute has a pickup or scooper blade movable by an actuator mechanism between a first position in which a second groove in the pickup blade is out of alignment with a first groove in the chute and a second position in which the first and second grooves are aligned with each other to allow headed parts as scooped from the hopper by the pickup blade to be fed in a row from the pickup blade to the chute. A rejector in the form of a bent wire is operatively connected to the hopper or chute and slidable along the second groove as the pickup blade approaches the second position to remove off-the-groove headed parts from the pickup blade to permit smooth supply of neatly arranged headed parts from the pickup blade to the chute.
