Part installation machine

A self-propelled part installation machine on which a part is mounted in a part mounting area, and which travels while matching with a movement path of a transfer system in a part installation work area located downstream of the part mounting area, and is capable of installing the part in an installation target body transferred by the transfer system,

• the part installation machine including a drive carriage section capable of traveling along a given travel path, a part mounting carriage section on which the part is mounted, and a coupling device which brings the drive carriage section and the part mounting carriage section into a coupled state, wherein
• the drive carriage section is capable of transporting the part mounting carriage section, with the drive carriage section and the part mounting carriage section brought into the coupled state by the coupling device,
• the coupling device is configured to bring the drive carriage section and the part mounting carriage section into a driving force separated state in which a driving force of the drive carriage section is not transmitted to the part mounting carriage section,
• the part mounting carriage section is provided with an engagement device which engages the part mounting carriage section with the transfer system in the part installation work area,
• the drive carriage section is provided with a relative position detection device which detects a relative position between the drive carriage section and the part mounting carriage section in a travelling direction when the part mounting carriage section is in the separated state, and
• the part installation machine is provided with a control device which, when the part installation machine enters the part installation work area, operates the coupling device to bring the drive carriage section and the part mounting carriage section from the coupled state into the separated state, and operates the engagement device so that the part mounting carriage section is engaged with the transfer system and is transported by the transfer system, and in this state, the control device controls a travelling speed of the drive carriage section such that the relative position detected by the relative position detection device is maintained within a predetermined range.
