The support stand 8 is fixed at the solid line position shown in FIG. 1A, the delivery device 6 is connected to the inlet side of the heating tube 2, and the heater H is energized. Next, connect the cassette 13 containing 20 to 30 crucibles C to the delivery block 12 of the delivery device 6, and tighten the fixing screw 14.
Fix it with. In this state, the cassette 13
As shown in Fig. 3, the lowest crucible C1 in the
Its center line CL 1 is the center CL 2 of plunger 9
Waits in a state that matches. Here, the drive unit 10
When the solenoid is energized, the plunger 9 makes a predetermined stroke to the right (total length of the crucible C).
, thereby causing the crucible C 1 to move one stroke to the right. Said plunger 9
immediately returns to the left, and the next crucible C 2 falls due to its own weight and enters the standby state as described above.

C1は約70分で加熱管２の出口端に到達する。 The delivery of the crucible by the plunger 9 is performed intermittently, and the delivery interval is determined by the heating characteristics of the heater H, etc., and is generally set to 1 to 3 minutes. In this way, the crucibles C are intermittently delivered one by one into the heating tube 2 over a certain period of time, and each crucible C is heated while moving to the right by the so-called Tokoroten method, and the delivery interval is set to 3 minutes. The first crucible delivered when set
C 1 reaches the outlet end of heating tube 2 in about 70 minutes.

ぎたるつぼＣは、出口側２ｂに向かうが、徐々に
冷却され、保持部１６に到達したときは約100℃
となつている。 Each crucible C is heated while moving within the heating tube 2, thereby being baked. In this case, since oxygen introduced from the inlet 19 is supplied into the heating tube 2, the organic matter adhering to or contained in the crucible C is completely combusted. After passing the heating area 3, the crucible C heads toward the exit side 2b, but is gradually cooled down to about 100°C when it reaches the holding part 16.
It is becoming.

停止する停止信号を送出する。 The crucible C' after the dry baking process is purged with oxygen introduced from the inlet 19 in the holding part 16, thereby being protected from contamination by outside air and the like. When two crucibles C' are accumulated in the holding section 16, an output signal is sent from the crucible detection device 18 to a control section (not shown). As a result, the control unit sends a stop signal to the delivery device 6 to stop delivery of the new crucible C.

状態となる。 When the lock lever 17a is operated to open the shutter and the crucible C' after the dry firing process is taken out from the take-out port 17, and a space is created in the holding part 16, the stop signal is released and the delivery device 6 becomes ready for delivery again. Become.
なお、カセツト１３内のるつぼＣの残量が設定
値以下になると、るつぼセンサ１５から出力信号
