The groove 21a of the pushing 20 is stopped at the position where the steel ball 23 is located. In this state, the upper end of the pusher 21 does not contact the slider 27VC in the bottom knob 24, and the steel ball 23 can enter the groove 21aVC, so the bottom cup 24 and the outer cylinder 25 remain connected, and the bottom knob 24 and the bushing 20 The connection with the is disconnected. The rotational position of the cam 32 is detected by numbering a plurality of small holes in the disk 34 corresponding to the stop position of the cam 32, and detecting the numbered small holes with a plurality of photoelectric detectors 35. be. The same conditions can be used when setting the pneumatic carrier on the stock table. FIG. 2 shows details of the chuck shown in FIG. 1, which is composed of the rotary solenoid 17 and the pawl 18, and the pawl 18 opens and closes using the fulcrum 16a.

18a is a spring that acts in the direction in which the claw 18 closes.

17a is a cam attached to the shaft of the rotary solenoid 17, and has an oval shape.
When energized, it rotates, and the long axis of the elliptical cam 17a comes into contact with the pawls 18 to push them apart.

When the excitation is turned off, the short axis of the cam 17a comes into contact with the pawl 18VC, so that the pawl 18 is closed by the spring 18a. In this way, the inner container is taken out from inside the pneumatic carrier. Place the pneumatic tube on the stocking table with the shaking hand and stock it, or remove the outer cylinder of the pneumatic tube and grasp the inner container again with the automatic hand, transfer it to another device, and close the lid of the inner container. It can be removed by an automatic machine and the transported object can be taken out.

Furthermore, it is possible to put the inner container filled with the conveyed material into the bottom cup of the pneumatic feeder using an automatic band, combine it with the outer cylinder, and then insert it into the pneumatic pipe of the pneumatic feeder again using the automatic hand. The related pneumatic carrier handling device serves as a link between the pneumatic device and the automatic machine, and greatly contributes to consistent automation. In the above embodiment, the table is of a rotating type and a plurality of pneumatic carriers are stored on the table, but the present invention is not limited to this. Needless to say, a single pneumatic carrier may be fixed to the pneumatic carrier. Furthermore, although the case is shown in which the inner container is provided within the pneumatic carrier, the same effect can be obtained even if the conveyed object is directly stored within the pneumatic carrier.
