NOZZLE WITH REPLACEMENT FUNCTION, NOZZLE DEVICE WITH REPLACEMENT FUNCTION, AND APPLICATION DEVICE WITH NOZZLE DEVICE WITH REPLACEMENT FUNCTION

摘要

In the present invention, functions of both a nozzle change drive mechanism configured to move a desired one of a plurality of nozzles to an ejection position and a nozzle moving drive mechanism configured to move the desired nozzle to apply a fluid to an application surface are realized by the nozzle moving drive mechanism. The present invention includes: a rotating portion(27) having first to third nozzles (23); a base portion (28) configured to support the rotating portion(27); a variable nozzle (22) configured to move a desired one (23) of the first to third nozzles to an ejection position (T) to eject a fluid, supplied from the base portion (28) side, from the desired nozzle; an engaging portion (47) provided at the rotating portion(27); and an engaged portion (48) provided at a mounting base(50), wherein the desired nozzle (23) is moved to the ejection position (T) by moving the base portion (28) by a robot arm with the engaging portion (47) engaging with the engaged portion (48).
