AIR-FEED BOX IN AIR FEED FACILITY

PURPOSE:To prevent a cartridge from coming off from a fit body composed of a jug and the cartridge, by providing such a structure that a vertically bi-split cartridge is fitted onto a jug so that cartridge is fed by air while it incorporates the jug. CONSTITUTION:An empty jug 2 fed by air from a jug supply air feed pipe 1, is fed into a rotor 3 in a stand-by condition. Therefore, the rotor 30 is rotated by 90 deg., and therefore, the jug 2 is discharged into a sampling bench. The jug 2 is fed again in the rotor 3 in the stand-by condition, after completion of sampling, and therefore, the rotor 3 is again rotated clockwise by 90 deg. and a holding body 11 is associated with rotation of the rotor 3, simultaneously. Therefore, a holding hole 4 in which a lower section cartridge 7 is disposed comes to the lower side of the rotor, and therefore receives the jug 2 dropping under the dead weight thereof. Then, the rotor 3 is rotated again clockwise by 90 deg. to move a fit body 10 of the jug and the cartridge to the position of an air feed pipe 5 for feeding out the fit part of the jug and the cartridge, and thereby it is possible to feed the fit part 10 of the jug and the cartridge into an analyzing chamber or the like outside of the system.
