Load an empty pneumatic head a into the receiver tube 22 of the support device 20 that has come to the manual position with the cap 3 facing upward. At this time, air carrier a
When loaded in the reverse position, that is, with the cap 3 facing down,
The cap 3 protrudes outward from a through hole 24 provided in the bottom plate of the receiver tube 22, and a photo sensor E2 detects this and instructs to load the pneumatic head in the reverse position, or a stopper provided on the rotary table 1 is used. The cap 3 of the pneumatic carrier hits and prevents the rotating table 10 from rotating. Next, when the lock cylinder C3 of the support device 20 is actuated to move the triangular cam 25 forward (see the position indicated by the solid line from the two-dot chain line in FIG. 7), the pair of clamping members 27 move toward the inside of the valley with the shaft 28 as a fulcrum. The arm-shaped outer end of the clamping member 27 holds the main body 2 of the pneumatic sender from the notch 23 of the receiver 22, and supports the empty pneumatic sender a sandwiched between the receiver 22. In the device 20, after the engagement key lock of the stop village 14 that moves downward by the operation of the solenoid 15 is released, the rotary table 10 rotates in the reverse direction, and the point P2 moves to the stop village 1.

This transmitting/receiving position 0 is also the position for receiving the return of the empty pneumatizer a from the station D on the analysis room side.

When the detector E of the pneumatic tube 1 detects the arrival of the empty pneumatic tube a, which is pneumatically conveyed through the pneumatic tube 1 from the analysis room side station D by the compressed air of the blower B, the cylinder C, The shutoff valve 18 is opened by the operation. From the position of the open cutoff valve 18, the empty pneumatic feeder a is received by the piston in the raised position of the lifting cylinder C2, and loaded into the receiver cylinder 22 of the support device 20 by the piston, which is simultaneously lowered. Then, the lock cylinder C3 of the support device 20 is activated, and the main body 2 of the pneumatic head is held between the holding members 27 in the same manner as described above. Next, the engagement lock between the stop village 14 and the point P2 is released, and the turning table 10 is rotated approximately 90 degrees until the point P3 joins the stop village 14. It rotates to the layer 30 position and stops, and the protrusions contact the second terminal from the top of the position detection switch 16 to indicate that the cap is at the detachable layer 30 position. When the detachable layer 30 at the upper limit position detaches from the cap 3 of the pneumatic head a, the movable plate 33 is guided by the guide rod 32 by the operation of the cylinder C4 and moves to the lower limit limit switch S.
3 and stops, the plug wrench 41 inside the protection tube 40 competes with the nut 8 of the cap 3, and the sleeve tube 4
2 presses the upper surface of the lid portion 5 of the cap 3 with the elastic force of the spring. Activate the cylinder C5 on the board 34 to activate the cylinder C5
5, both engaging members 43 are closed via each link piece 44, and the claw plate at the lower end of the engaging member 43 engages with the rim 4 of the cap 3 (see FIGS. 9 and 10). When the motor 37 is rotated, the plug wrench 41 rotates and the nut 8 is rotated.
At the same time, after the compression of the expansion plug 6 by the bottom of the bolt 7 and the lid 5 is released, the cylinder C4 is operated to raise the movable plate 33 to the upper limit switch S2,
The cap 3 is removed from the main body 2 of the pneumatic tube, and the way the plug wrench 41 rotates can be seen by looking at the window 39 of the protective tube 40 so that the striped pattern etc. on the surface of the plug wrench 41 rotates.
You can be more competitive. Then, stop pestle 1 4 and point P3
When the engagement lock is released and the rotary table 10 is further rotated about 90 degrees until the point P4 engages with the stop punch 14,
The support device 20, which holds the main body 2 of the pneumatic tube from which the cap 3 has been removed, advances to the position of the sample injection device 50, and
The protrusion L contacts the topmost terminal of the position detection switch 16 to indicate the presence of the sample injector 50 .

When the support device 20 moves in, the cup 60 of the injection device 50, which is on its path and receives the residual dust that falls from the injection tube 58 after the sample is injected, is pushed against the spring by the receiving tube 22 from directly below the injection tube 58. and half a turn outward,
The joint 22 will be located directly below the injection pipe 58. When the injection device 50 at the upper limit position injects a fixed amount of sample into the main body 2 of the pneumatic tube, the moving plate 5 is moved by the operation of the cylinder C6.
3 descends while being guided by the guide bar 52 and stops, the injection tube 58 slides into the chute section 61 and inserts its lower end through the closed opening of the main body 2 of the pneumatic tube, and at the same time the flat plate 5 descends.
A dustproof cylinder 57 fixed to 5 covers the upper part of the joint 22.
A fixed amount of sample is injected into the main body 2 of the pneumatic carrier through the chute part 61, and at the same time, the pipelator b is operated to prevent the sample from adhering, and a separate suction machine (not shown) is operated to remove dust generated during injection. The sample is removed from the suction pipe 56, and the cylinder C6 is operated to return the movable plate 53 to the upper limit position, thereby completing the sample injection. The support device 2 which clamps the main body 2 of the pneumatic tube into which the sample has been injected is returned to the position of the cap attachment/detachment platform 30 by rotating the rotary table 10 in the opposite direction to that described above, and the cap 3 is attached.

The detachable layer 30, which detaches and holds the cap 3, is at the upper limit position, and the moving plate 33 is lowered to the lower limit position by the operation of the cylinder C4, and the cap 3, which is engaged with the engagement member 43, is pneumatically moved. Insert it through the opening of the main body 2 of the child. When the motor 37 rotates in the opposite direction, the plug wrench 41 rotates and tightens the nut 8, and the expansion plug 6 between the bottom of the bolt 7 and the lid 5 is compressed from above and below, expanding its circumferential side. Then, it is crimped and fixed to the inner wall of the main body 2 of the pneumatic tube. When the expansion plug 6 is sufficiently expanded and crimped, the motor 37
The repositioned plate 38 slightly rolls in the rotational direction against the spring 35 of the base plate 34, and the torque limit switch S4 detects this rolling and stops the motor 37 to ensure safety. Next, operate cylinder C5 to activate cylinder C5.
When 5 is pressed, both engaging members 43 open and disengage from the cap 3, and the moving plate 33 is raised and returned to the upper limit switch S2 by the operation of the cylinder C4. In this way, the cap 3 is Attach it to the main body 2 of the pneumatic carrier.
Furthermore, when the support device 20 supporting the main body 2 of the pneumatic tube in which the sample has been injected and the cap 3 attached is returned to the transmitting/receiving position 0 by the rotation of the rotary table 10 in the opposite direction to that described above, the lock cylinder C3 is moved. When the triangular cam 25 is actuated and moved rearward, the pair of holding members 27 rotate outward, and their arm-shaped outer weave portions release the pneumatic head from being clamped to the main body 2.

Then, after the piston of the cylinder C2 for raising and lowering the pneumatic sender is raised to raise the pneumatic sender a from the receiving tube 22 to the pneumatic pipe 1, the suction air of the blower B is used to move the pneumatic sender a to the station D on the analysis room side.
The sample is conveyed by air through the pneumatic feed tube 1, and the above operations can be repeated to automatically transmit and receive the sample. As is clear from the above description, according to the present invention, the following effects can be achieved.

First, receiving an empty pneumatizer, rotating and removing the cap of the received pneumatizer, injecting the sample into the pneumatizer that has taken off the cap, and replacing the cap on the pneumatizer into which the sample has been injected. A series of tasks such as rotating the device, attaching it, and transmitting the pneumatic carrier with the cap attached can be performed automatically. Second, since the pneumatic carrier is supported by a support device and rotated back and forth, and the series of operations described above are performed on the movement path, the area occupied by the station can be reduced.

Thirdly, by automating the series of operations described above, the complexity of manual sample sampling operations can be eliminated, and the number of workers can be reduced, contributing to labor savings in factories and the like.
