In a part-mounting system formed by linking plural part-mounting devices which carry out respective process steps of part-mounting, when a production tact-time of one of the devices varies beyond a given variation range, a tact-time change signal is sent to other devices located at upstream and/or downstream of the device via a communicating section. The other devices receive the tact-time change signal and changes their own work tact-times from the ones corresponding to a productivity-oriented mode to a slower tact-pattern corresponding to a quality-oriented mode. Thus every device constituting the system can accommodate a tact-time variation due to a tact-time delay of any part-mounting device. As a result, the quality appropriate to the tact-time can be secured.
A part-mounting system formed by linking a plurality of part-mounting devices for mounting parts onto a board, said system comprising:
A first part-mounting device of a part-mounting system which is formed by linking a plurality of part-mounting devices, said first part-mounting device comprising:
A method of mounting a part on a board by linking a plurality of part-mounting devices and having the respective devices carry out respective process steps of part-mounting, said method comprising the steps of:
