An application apparatus includes a nozzle device () injecting a damping material from a nozzle hole () to a vehicle body, an articulated robot () moving the nozzle device () relative to the vehicle body, a supply section including a supply pump (), and a supply passage (), and continuously driving the supply pump () to continuously supply the damping material from the supply pump () to the supply passage () in a substantially uniform amount, a return passage () branched from the supply passage () and returning the damping material to the supply pump (), and a gun () and a return valve () switching a supply destination of the damping material between the nozzle hole () and the return passage () based on information on applying the damping material to the vehicle body.

Application apparatus for applying cohesive material to application target

A multi-color rotary spraygun has a bell-shaped head which is supported for rotation on a front end of a casing. The front end portion of the bell-shaped head is covered with a partition wall having coating material spraying ports. A plurality of coating material lines open into the bell-shaped head at their front ends and are respectively connected to separate coating material sources at their base ends. A coating material supplied to the bell-shaped head from one of the coating material sources through one of the coating material lines is atomized and sprayed on an object through the spraying ports by rotation of the bell-shaped head. The front end portion of a cleaner line which is connected to a cleaner source at its base end is disposed in the bell-shaped head and the front end portion of the coating material lines are disposed around the front end portion of the cleaner line.
