Abstract:
1. A component mounting apparatus comprising: a conveyor line comprising a plurality of substrate conveying conveyors which are arranged in parallel and each of which is configured to convey a substrate and comprises a substrate holding unit configured to position and hold the substrate; a component supplying unit positioned lateral to the conveyor line, and configured to supply a component to be mounted to the substrate; a substrate distributing unit configured to distribute substrates delivered from an upstream apparatus to the plurality of substrate conveying conveyors; a substrate conveyance controlling unit configured to control the substrate distributing unit and the substrate conveying conveyors, thereby performing a substrate conveying operation of carrying in a delivered substrate into the substrate holding unit of any one of the substrate conveying conveyors; a component mounting mechanism configured to pick up a component from the component supplying unit by a mounting head, and configured to mount the component to the substrate positioned and held by the substrate holding unit; and a signal outputting unit configured to determine, based on a result of a detection of existence or non-existence of a substrate in the substrate conveying conveyor, whether the substrate conveying conveyor is in a state where the substrate conveying conveyor can receive a new substrate or not, and configured to output, based on a result of the determination, a substrate request signal for requesting carrying in of the new substrate into the substrate conveying conveyor, wherein in a case where the substrate request signal is output for one of the plurality of substrate conveying conveyors which is farther from the component supplying unit, if the substrate request signal is output for one of the plurality of substrate conveying conveyors which is closer to the component supplying unit based on the result of the determination prior to start of a transferring operation of carrying the new substrate from the substrate distributing unit into the substrate conveying conveyor which is farther from the component supplying unit, the substrate conveyance controlling unit causes the new substrate to be carried into the substrate conveying conveyor which is closer to the component supplying unit in preference to the substrate conveying conveyor which is farther from the component supplying unit, irrespective of a distance between any of the plurality of substrate conveying conveyors and a current position of the substrate distributing unit.
