Abstract
A coating material is uniformly applied on an inner wall surface of a container while preventing leakage of the coating material and an increase in an installation space. An application apparatus (10) that applies a coating material (L) on an inner wall surface of a container (C) includes: a spray gun (20) having a spray nozzle (22); an outgoing pipe (30) and a return pipe (33); a supply control unit (50); a rotary drive unit (60); and a moving unit (70), wherein the outgoing pipe (30) and the return pipe (33) are each provided with a resilient-shape part (32, 35) capable of extending and contracting resiliently.
Claims8
An application apparatus that applies a coating material on an inner wall surface of a container, comprising:
- a spray gun having a spray nozzle and including a coating material ejection passage formed therein;
- an outgoing pipe and a return pipe attached to said spray gun and forming a coating material circulatory path connecting to said coating material ejection passage;
- a supply controller that controls supply of the coating material from said coating material circulatory path to said coating material ejection passage;
- a rotary driver that rotates said spray gun around an axis extending along a longitudinal direction of the gun;
- a mover that moves said spray gun along the longitudinal direction of the gun;
- and
- an aspirator that can be positioned opposite a container opening, wherein
- said outgoing pipe and said return pipe which are attached to the outer periphery of the rotatable spray gun are each provided with a resilient-shape part formed in a coil shape capable of extending and contracting resiliently,
- said aspirator includes an airflow augmentation unit,
- said airflow augmentation unit including an airflow augmenting passage having a gas supply part, a suction port, and an ejection port,
- said suction port being disposed opposite the container opening, and
- said airflow augmentation unit is disposed such that a shaft of said spray gun is positioned inside said airflow augmenting passage.
