Component mounting line

A component mounting line, in which multiple component mounting machines are arranged along a conveyance path of a circuit board, and components, being supplied from a feeder setting base of each component mounting machine, are mounted on the circuit board by the multiple component mounting machines, the component mounting line comprising:

• an automatic exchanging device, moving alongside a front face of the component mounting line in an arrangement direction of the multiple component mounting machines, which sets and/or removes a feeder to and/or from the feeder setting base of each component mounting machine,
• in which the automatic exchanging device is configured to set and/or remove the feeder by moving to a front of a component mounting machine of the multiple component mounting machines at which an automatic exchange request for setting and/or removing the feeder is generated,
• in which each of the component mounting machines and/or the feeder setting base of the component mounting machines is configured to enable an operator to pull out the component mounting machine and/or feeder setting base toward a front face side of the component mounting line, and
• a section management computer configured to prohibit a pull-out operation of a predetermined number of the multiple component mounting machines, from the component mounting machine of the component mounting machines facing the automatic exchanging device toward a position of a component mounting machine of the component mounting machines at which a new automatic exchange request has been generated.
