Claim of US Patent No. 10,561,050

1. A component mounting system including multiple feeders configured to be exchanged in respective a feeder setting area of respective multiple component mounting machines which are arranged along a conveyance path of a circuit board, the circuit board being conveyed to the multiple component mounting machines in order and components which are supplied from the multiple feeders are mounted onto the circuit board using each of the component mounting machines to produce a component mounted board, the component mounting system comprising:a feeder stocking area including feeders to be exchanged with feeders for which exchanging is necessary from among the multiple feeders set in the feeder setting area of each of the component mounting machines;
an exchanging robot which removes the feeders for which exchanging is necessary from the feeder setting area of each of the component mounting machines, sets the feeders for which exchanging is necessary in the feeder stocking area, removes the feeders to be exchanged from in the feeder stocking area, and sets the feeders to be exchanged in the feeder setting area of the respective component mounting machine; and
a control device configured to control the exchanging robot when a board type to be produced in each of the component mounting machines is switched from a first board type to a second board type, to perform a feeder exchange process before a board type switching in parallel with a component mounting process onto a final circuit board of the first board type,
wherein in the feeder exchange process before the board type switching, the control device controls the exchanging robot to remove feeders from the feeder setting area which are not used in production of the second board type among feeders necessary for the component mounting process onto the final circuit board of the first board type and to set the feeders which are not used in the production of the second board type in the feeder stocking area, and to remove feeders to be used in the production of the second board type from the feeder stocking area and sets the feeders to be used in the production of the second board type in the feeder setting area of the component mounting machine.
