Abstract: A parts feeding apparatus includes a parts feeding table detachably supporting parts cassettes. A working area wherein a rail is laid and a standby area are arranged in parallel with each other. A box or frame constituting a table positioning unit is movably supported on the rail. In feeding parts, the table is loaded on the box by a table transport unit provided between the working area and the standby area, and the box is moved on the rail, whereby the table is positioned such that the parts cassette can be brought at a parts taking-out position. The table transport unit unloads the table being laid on the box and transports the table thus unloaded to the standby area, and transports the table from the standby area to a charge station or transports the table from the charge station to the standby area.

Abstract: An assembling apparatus includes a mounting table on which a printed circuit board is supported by back-up pins held on a base plate. The mounting table is movable in an X direction and a mounting head for mounting electronic parts on the printed circuit board is movable in a Y direction. A back-up pin stocker is provided in the vicinity of the base plate, which stores spare back-up pins being not used. A replacing unit is provided attached to the mounting head to be movable between the base plate and the back-up pin stocker together with the mounting head so that the back-up pins held on the base plate can be replaced with the back-up pins stored in the back-up pin stocker on the basis of data representative of the type of a printed circuit board, etc. by the replacing unit when the printed circuit board to be assembled is changed.

Abstract: A parts feeding system includes an unmanned conveying machine, capable of conveying a parts carriage holding a plurality of parts cassettes thereon and movable along a guide track which is laid on a floor, one or more parts mounters and a logistics base provided with a parts stocker. The parts carriage is returned to the logistics base by the unmanned conveying machine for supply or exchange of parts. The work in the logistics base is performed by a worker or robots. The parts carriage loaded with required parts cassette is delivered to an assigned parts mounter by the unmanned conveying machine. Each of the parts mounters includes a track for a carriage carrier moving thereon, which includes a work station where the parts are picked up, and a carriage change station where the parts carriage is loaded to the track from the unmanned conveying machine or vice versa.
