AUTOMATIC PNEUMATIC PROJECTILE LAUNCHING SYSTEM

摘要

An automatic pneumatic projectile launching system (10) is disclosed for automatically launching cleaning projectiles into a hose. The system comprises a launcher housing (16) defining a chamber (14), and a shuttle (12) having a recess (22) for receiving a projectile and a first shuttle aperture (24) in fluid communication with the recess, the shuttle being disposed in and being reciprocably moveable relative to the chamber (16) between a first position wherein a projectile is receivable in the recess (22) and a second position wherein the first shuttle aperture (24) is communicable with a source of compressed air. The system (10) also includes a feeder mechanism (20) for transferring projectiles to the shuttle (12), projectile releasing means (50) for selectively releasing a projectile into the recess (22), and logic control means (49) operatively connected to the projectile releasing means (50) for activating the projectile releasing means (50) so as to release projectiles one at a time into the recess (22).
