する。Here, the cylinder C2 of the support device 20 pushes out the triangular cam 34, and the pair of clamping members 37 rotate around the shaft 36, and the tip of the clamping member 37 passes through the notch 31 of the receiving tube 27, and the pneumatic feeder a to hold. The support device 20 that supports the air feeder a in the receiving tube 27 is moved to the point P2 by the solenoid 15.
At the same time as the stop lever 14 is removed from the cap, the motor 12 is activated and the rotating table 10 is rotated.
Move to the position. When the protrusion L3 is fused to the position detection switch 16, the motor 12 is stopped and at the same time the stop rod 14 is stopped.
is locked at point P3, and the pneumatic head a stops directly below the plug wrench 51 of the attachment/detachment device 40. In the attachment/detachment device 40, the base plate 44 is lowered by the operation of the cylinder C3, and the plug wrench 51 is fitted into the cap nut 8 of the air feeder a. Here, the cap nut 8 is rotated by the motor 47 to release the tightening of the bolt 7, and after releasing the compression of the expansion plug 6, the claw plate 5 at the tip of the engagement member 54 provided on the base plate 44 is released.
3, grip the cap and raise the board 44. The pneumatic probe a, which has been released from the cap 3, is further moved by the operation of the motor 12 as the stop lever 14 is released, and heads toward the sample extraction device 80. Incidentally, since the sample powder is attached to the detached cap 3, after the support device 20 has moved, the cleaner 60 that was waiting is rotated and moved directly below the cap by the action of the cylinder C5, and the cap 3 is moved to this cleaner 60.
is inserted downward into the main body 63 of the cap 3, and the sample powder is swept away by the brush 64, and at the same time, the cap 3 is cleaned by suction from the dust exhaust hose (see FIG. 5). Cleaned cap 3
rises again, and the cleaner 60 rotates and returns to its original position. The support device 20 that has been moved into the sample extraction device 80 with the door 81 open (see FIG. 9) moves to the protrusion L4.
contacts the detection switch 16 and the motor 12 stops, and at the same time the stop rod 14 locks to the point P4, and the box 83
Stop inside. The door 81 is closed by the operation of the cylinder C6, and the center hole 86 of the box 83 and the collar 26 of the support device 20 are closed.
come into contact with each other, and the box 83 is in a sealed state. When the rotating rod 88 that is locked to the projecting piece 32 of the receiver tube 27 inside the box 83 is rotated by the motor 87, the receiver tube 27 and the pneumatic head a fixed thereto are also rotated in half, and the air feeder is rotated in half. The sample in the sample a falls through the chute 82 and is sent to the analysis room. When the motor 87 reverses and returns to its original state, compressed air is injected into the pneumatic tube a, and the remaining sample powder in the box 83 and the pneumatic tube a is removed by suction from the dust removal hose 101. door 8
1 opens, the rotating table 10 rotates in the opposite direction, and the pneumatic carrier a supported by the support device moves to the cap attachment/detachment device 40.

When the cap 3 is lowered, the cap 3 is inserted into the pneumatic carrier a, and the motor 47 rotates in the opposite direction to when the cap is removed, and the expansion plug 6 is crimped and fixed inside the pneumatic carrier a by tightening the bolt 8.
At this time, when the torque of the motor 47 that rotates the nut 8 increases to a certain value due to the frictional force generated between the expansion plug 6 and the inner wall of the air feeder a, the nut 8 rolls against the pressing force of the spring 45. Since the plate 48 rolls slightly and the torque limit switch S4 is turned on to stop the motor 47, the cap 3 is fixed to the air balloon a with an appropriate pressure. cap 3
The empty pneumatic tube a equipped with the pneumatic tube 1 returns to the bottom of the pneumatic tube 1 by the movement of the support device 20, and is released from the support device 20.
It is pushed up into the pneumatic tube 1 by the tip of the cylinder C, and sent to an arbitrary sample collection station C by the prower B.
