The lower end of is connected to and communicates with the air pipe 50. further,
A striking device C that moves up and down by an appropriate mechanism such as a cylinder is disposed near the upper portion of the chute 49.

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 33 through the inlet 35 provided by inserting the probe P, the gripping member is pulled up and the probe P is directed to the upper chute 7 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 supplying the sampled probe P to the feeding chute 7, as shown in FIG. 13, the positioning clamp 8 of the positioning mechanism is open, the upper and lower shutters 9 and 10 are closed, and the first and second clamps 1 are arranged. 2 is in an open state, and when the lower end of the probe P passes from the feeding chute 7, the lower end surface of the probe P is received by the upper shutter 9 and the probe P is temporarily stopped. At this time, the upper shutter 9
Since it is slidably supported by the gantry F, it falls from a high place.
Even if it receives an impact force when receiving the probe P
Never. Then, the impact force acting on the upper shutter 9 at that time is detected by an appropriate detecting means to detect the reception of the probe P.

Upon detection thereof, the cylinder 42 of the upper shutter 9 is actuated, pulling the upper shutter 9 and releasing the reception of the probe P. The probe P drops in the intermediate chute 43 due to the opening, and the lower end thereof reaches the lower shutter 10 while being guided vertically by the intermediate chute 43, and is received on the shutter 10 as shown in FIG. Stop. At this time, the drop height of the probe P is low, so
The impact force of the shutter is small and the shutter 10 and its vertical rotation cylinder
Does not damage the 45. Further, in this state, the lower end locking end surface 37 of the upper large-diameter paper tube portion 30 of the probe P reaches the upper proximity position of the positioning clamp 8.

When the probe P comes into contact with and is received by the lower shutter 10, the impact force acting on the lower shutter 9 at that time is detected by an appropriate detecting means in the same manner as described above, and at the same time as the reception of the probe P is detected. , The detection signal is transmitted to the positioning clamp 8 and the clamp piece 8 of the positioning clamp 8 is transmitted.
Cylinder pieces 8a, 8a
The semicircular locking surfaces 41, 41 are closed so as to surround the upper end of the small-diameter paper tube portion 29 of the probe P. At this time, the clamp piece
8a, centering plate piece 8 integrally provided on the lower side of 8a
The concave arcuate end faces 51, 51 of b, 8b pull the probe P onto the vertical center line.

In conjunction with this closing, the cylinder 45 of the lower shutter 10 is actuated, the lower shutter 10 falls vertically in the lower chute 44 to open the reception of the probe P, and
The swiveling cylinder 48 is operated to retract the lower chute 44 together with the lower shutter 10 from the lower side of the feeding path of the probe P to the lateral side, so that the subsequent probe cutting process can be performed without trouble. Of course, the lower shutter 10 and the lower chute 44 may be fixed to a fixed position on the drop line of the probe P so as not to interfere with the cutting of the probe P.

When the lower shutter 10 is retracted, the probe P
When the support is released, the probe P falls, but at the time of a slight drop, the lower end locking end surface 37 of the large-diameter paper tube portion 30 is received on the clamp pieces 8a, 8a of the positioning clamp 8, and FIG. As shown in FIG.
Vertical state, and the molten metal receiving tube to be cut 32
The lower small-diameter opening portion of is placed on the movement path of the cutting device B.

Furthermore, the clamp pieces 1a, 1a of the first clamp 1 are closed in conjunction with the retreat of the lower shutter 10, and the small clamping papers 3, 4 of these clamp claws 4, 4 make the small-diameter paper of the probe P. The upper end portion of the tube portion 29 is pulled toward the vertical center line so as to be clamped, and the clamp pieces 2a, 2a of the second clamp 2 are also closed at the same time to close the clamp pieces 2a, 2a.
The pinching surfaces 3,3 to sandwich the molten metal sampling chamber 33 portion of the probe P. The positioning clamp 8 is opened in synchronism with this sandwiching process and stands by for the next supply of the probe (FIGS. 16 and 17 ).

The probe P has the first and second clamps 1 and 2.
When it is clamped by, the feed motor 28 and the cutter rotation driving motor 6 of the cutting device B are operated in conjunction with it,
The circular cutter blade 5 advances toward the probe P side at a predetermined feed speed while rotating and the ceramic molten metal receiving tube 32 at the upper end of the molten metal sample collecting chamber 33 of the probe P.
Cut the bottom small-diameter opening part of XX (see Figure 12). This
The diameter is gradually increased toward the upper end of the opening by cutting
Top opening of a frustoconical iron sampling chamber 33
The upper end surface of the sample block D is exposed from the portion.

The circular cutter blade 5 of the cutting device B is a motor 6
The center is integrally fixed to the upper end of the rotating shaft 52 that is rotated by the
As shown in 12, a circular cutter blade 5a having the same size and shape as the circular cutter blade 5 is fixedly attached, and the lower portion of the molten metal sample collecting chamber 33 is cut YY by the circular cutter blade 5a. It is preferable that the molten metal sample collecting chamber 33 is cut in the lower part in this way, so that the sample taking step described later can be performed more smoothly.

When the molten metal sample collecting chamber 33 is cut off from the lower end of the probe P in this way, the circular cutter blades 5 and 5a are retracted by the reverse rotation of the feed motor 28 and stopped rotating and stand by for the next cutting. On the other hand, the cylinder 22 operates in conjunction with the retreat, and the swivel base 18 on which the second clamp 2 holding the molten metal sample collection chamber 33 is disposed swivels toward the chute 49 on the air pipe 50 side. Moving. When the lower shutter 10 is retracted when the probe P is cut, after the cutting, the lower shutter 10 is returned to the vertically downward position of the cut probe P with the lower shutter 10 opened. I am configuring.

When the molten metal sample collecting chamber 33 held by the second clamp 2 reaches on the chute 49, the motor
When 53 is operated and the reversing movable table 20 integrated with the horizontal shaft 19 is reversed by 180 degrees, the molten metal sample collecting chamber 33 is reversed so that the large-diameter open end of the collecting chamber 33 is directed downward. The striking device C operates in conjunction with the completion of the downward movement, and strikes the upward outer bottom surface of the sampling chamber 33 or an appropriate position of the clamp 2 to separate the sample mass D from the sampling chamber 33, and the chute 49
Drop it inside. The sample lump D that dropped is an air pipe 50
Is pneumatically transported to the analysis room.

On the other hand, when the second clamp 2 starts to move to the chute 49 side, the first clamp 1 is interlocked with the movement.
The clamp pieces 1a, 1a of the above are opened, and the grasping of the probe P cut in the sampling chamber 33 part is released, and it is dropped from the opened lower shutter 10 through the lower chute 44 to the lower side of the gantry F to be properly stored. Store in a box and discard.

Thus, when the first clamp 1 is opened and the excised probe P in the sampling chamber 33 is dropped, the upper shutter 9 is closed to wait for the next probe P to be received and the sample mass D to be collected. The second clamp 2 which holds the empty empty sampling chamber 33 returns to its original position by the return movement of the swivel base 18, and the clamp pieces 2a, 2a of the second clamp 2 are opened at that position. Empty collection chamber 33 and lower chute 44
Through the lower shutter, and then lower shutter 10
Is closed and the preparation for the next cutting process of the probe P is completed. The lower chute 44 does not necessarily have to be provided.

The above-mentioned operation of each mechanism is electrically or mechanically interlocked via an appropriate detecting means so as to be sequentially operated according to a predetermined time schedule, and is supplied to the feeding chute 7. P is sequentially cut and the sample mass D is taken out from the collection chamber 33 and sent to the air transport pipe 50. The present invention is particularly characterized by the clamp mechanism and the cutting mechanism of the probe P. The chute for feeding the probe P to the clamp mechanism, the probe positioning mechanism, and the like are not necessarily configured as described above, and other mechanisms may be adopted. It is also possible to perform positioning.
