1. US20210068321 - Component mounting system

A component mounting system including multiple component mounting devices to collect components from feeders set at multiple feeder holding sections and mount the components on a board, the multiple feeder holding sections being provided on each of the multiple component mounting devices to removably hold the feeders; and a feeder exchanging device to move along a line along which the multiple component mounting devices are arranged and exchange feeders with respect to each of the component mounting devices. The component mounting system acquires a type and arrangement of each of the feeders set on the multiple component mounting devices, determines whether each of the feeders is set at a predetermined appropriate position, and upon determining that there is a feeder that is not set at the appropriate position, uses the feeder exchanging device to reset the feeder that is not set at the appropriate position.
