The operation of the apparatus in the embodiment thus constructed will be described. First, the probe P is held by the tip of an appropriate holding member (not shown), and the holding member is placed in the molten metal furnace. After the sample is collected in the sample collection chamber 43 through the inlet 45 provided by inserting the probe P, the gripping member is pulled up and the probe P is directed to the upper chute 4 and the sample collection chamber portion is directed downward. Send in the state. It should be noted that the sampling of the sample from the molten metal furnace by such a holding member may be performed manually, but is performed using an appropriate automatic sampling device (not shown).

When the sampled probe P is supplied to the feeding chute 4, the positioning clamp 1 is open, the shutters 5 and 6 are closed, and the upper and lower clamping clamps 2 and 7 are open, as shown in FIG. When the lower end of the probe P passes from the feeding chute 4 to the lower end of the opening of the intermediate chute 49, the lower end surface of the probe P is received by the intermediate shutter 6, and the probe P is temporarily stopped in the vertical state. This
At this time, the intermediate shutter 6 is slidably supported by the frame F.
Therefore, when receiving the probe P falling from a high place,
It will not be damaged by impact. Then, the impact force acting on the intermediate shutter 6 at that time is detected by an appropriate detecting means to detect the reception of the probe P.

The cylinder 48 of the intermediate shutter 6 is activated by the detection, and the intermediate shutter 6 is retracted to open the reception of the probe P. By the opening, the probe P descends while being vertically guided by the intermediate chute 49, and the lower end thereof reaches the lower opening / closing shutter 5, and is received on the shutter 5 and stopped as shown in FIG. This time

The upper portion of the paper tube portion 38 is pulled up toward the vertical center line to be clamped, and the clamp pieces 2a, 2a of the lower clamp clamp 2 are also closed at the same time so that the probe P is melted by the clamping surfaces 31, 31 of these clamp pieces 2a, 2a. The metal sampling chamber 43 part is clamped. The positioning clamp 1 is opened in conjunction with this sandwiching process, and stands by for the next probe supply (FIGS. 16 and 17 ).

When the probe P is clamped by the upper and lower clamps 2 and 7, the feed motor 37 of the cutting mechanism 3 and the cutter rotation driving motor 9 are operated in conjunction with it, and the disk cutter 8 rotates while the probe P side. By a link motion toward a straight line at a predetermined feed rate, the small-diameter opening bottom of the ceramic molten metal receiving cylinder 42 at the upper end of the molten metal sample collection chamber 43 of the probe P is cut XX. At the time of this cutting, the opening bottom of the molten metal receiving cylinder 42 made of ceramic is crushed by the cutter 8 and sealed.
Removed from 44 to facilitate removal of the sample mass D from the inverted frustoconical sample collection chamber 43.

When the molten metal sample collecting chamber 43 is cut off from the lower end of the probe P in this way, the disk cutter 8
While waiting for the next cutting in a state where it is retreated by the reverse rotation of the feed motor 37 and stopped its rotation, the cylinder 16 is operated in conjunction with the retreat and the lower clamping clamp holding the molten metal sample collection chamber 43 is held. The swivel base 17 provided with the two swivels and moves toward the chute 47 on the air transport pipe 50 side. In addition,
In the case where the lower opening / closing shutter 5 is configured to retract when the probe P is disconnected, the probe 5 is configured to return to the vertically downward position of the disconnected probe P with the shutter 5 opened after the disconnection. ing.

When the molten metal sampling chamber 43 held by the holding clamp 2 reaches the chute 47, the motor
26 is operated and the reversing movable table 19 integrated with the horizontal shaft 18 is reversed by 180 degrees, and the molten metal sample collecting chamber 43 is reversed so that the large-diameter open end of the collecting chamber 43 is directed downward. The striking device 56 is operated in conjunction with the completion of the downward movement, and the upper outer bottom surface of the sampling chamber 43 or the appropriate position of the clamping clamp 2 is tapped to disengage the sample block D from the sampling chamber 43 and shoot. Drop into 47. The sample lump D that has fallen is pneumatically transported to the analysis chamber by an air transport pipe 50.

On the other hand, when the lower clamp 2 starts moving to the chute 47 side, the clamp pieces 7a, 7a of the upper clamp 7 are opened in conjunction with the movement, and the probe P cut off the sampling chamber 43 is cut off. The grip is released from the opened lower opening / closing shutter 5 through the lower chute 51 to the lower side of the gantry F, and is stored in an appropriate storage box or the like and discarded.

In this way, when the first clamp 1 is opened and the excised probe P in the sampling chamber 43 is dropped, the intermediate shutter 6 is closed to wait for the next probe P to be received and the sample mass D to be collected. The clamping clamp 2 that holds the empty empty sampling chamber 43 returns to the original position by the return movement of the swivel base 17, and the clamp piece of the clamp 2 at that position.
2a, 2a are opened and the empty sampling chamber 43 is dropped downward through the lower chute 51, and then the lower opening / closing shutter 5
Is closed and the preparation for the next cutting process of the probe P is completed. The lower chute 51 does not necessarily have to be provided.
