本発明は、誘導加熱において円板等の被加熱物を順次連
続的に加熱する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for sequentially and continuously heating an object to be heated, such as a disk, in induction heating.
直径に対し厚さが比較的に薄い円板状の被加熱物（以下
「ワーク」という。）を連続的に加熱するために従来か

〔１〕ワーク積み重ね方式
これは、第１図に示すように、誘導加熱コイル（以下「
ワークコイル」という。）内側に耐火物製の案内管（２
）を配し、その中に多数のワーク（３）を積み重ねた状

次のような欠点がある。[1] Work stacking method As shown in Figure 1, this method uses an induction heating coil (hereinafter referred to as "
It's called a "work coil." ) Inside is a refractory guide tube (2
), heating is performed with a large number of workpieces (3) stacked therein, and one workpiece is heated from below in each cycle.
This is a method in which the workpieces are fed one by one and then discharged one by one from above to move the workpieces one by one. However, this method has
It has the following drawbacks:
（イ） ワーク間で溶着が起こり易い。高周波誘導加熱
の特徴としてワークの外周や角（かど）の部分の温度が
特に高くなるため、排出部付近でワークの外周部分が互
いに溶着し易い。(a) Welding easily occurs between workpieces. A characteristic of high-frequency induction heating is that the temperature at the outer periphery and corner portions of the workpiece is particularly high, so the outer circumferential portions of the workpieces tend to weld together near the discharge section.
（ロ） ワークが均等に加熱されない。ワークは積み重
なったまま上方へ移動するだけであるから、ワークの周
辺に温度むらができ易い。(b) The workpiece is not heated evenly. Since the workpieces are simply moved upward while remaining stacked, temperature unevenness is likely to occur around the workpieces.
〔２〕ワークを平面に並べる方式
これは、第２図に示すように、ワーク（３）をスキット
レール（２’） （耐火物製或いは水冷式）上に平面に
並べてプッシャーで１個ずつ供給すると同時に排出する
方法である。この方式にも、次のような欠点がある。[2] Method of arranging workpieces on a flat surface As shown in Figure 2, in this method, the workpieces (3) are arranged on a flat surface on a skit rail (2') (made of refractory or water-cooled) and fed one by one using a pusher. This is a method of discharging it at the same time. This method also has the following drawbacks.
（イ）加熱効率が悪い。(a) Poor heating efficiency.
（ロ） ワークコイル（１）内接収容しているワーク（
３）の数が少ないため、電磁力が強く働いてワークの整
列が乱れ易い。(b) Work coil (1) Internally accommodated work (
3) Since the number is small, the electromagnetic force acts strongly and the alignment of the workpieces is likely to be disturbed.
（ハ） ワーク（３）が均等に加熱されない。(c) Workpiece (3) is not heated evenly.
に） ワーク（３）の相互接触部が放電したり、傷が付
いたりし易い。) Mutual contact parts of the workpiece (3) are prone to discharge or scratches.

This constitutes a driving means for rotating both intermittently or continuously in the same direction at the same time, but there is nothing particularly new about it, so a detailed explanation will be omitted. In addition, work supply rail (goods)
The part from the pneumatic cylinder to the wharf is a means for continuously supplying the workpieces (3) one by one, but such a supplying means itself is publicly known except for the workpiece supply rail (c). Therefore, detailed explanation will be omitted. That is, the workpiece supply rail (c) is aligned in the direction of the threaded trough of the threaded rod so that the workpiece (3) can be guided to the threaded trough of the threaded rod. The work coil (1), that is, the heat insulating cover (4) is rotated by the drive means to rotate the threaded rods (5) to (7).
) for supplying the workpiece (3) from the external drive side end;
The workpiece (3) is guided to the trough of the thread of the threaded rod and moves within the workpiece coil (1) at a constant speed as the thread advances.

（７）の先端との間には間隙が設けである。At this time, the workpiece (3) is rotated by the rotation of the threaded rod. When the target heating temperature is reached at the other end of the screw rod, the workpiece (3) is dropped from the top of the screw and discharged by the drop guide plate (F) and discharge chute (C). Figure 6 shows
It is a perspective view which expands and shows such a discharge means. As can be seen from the figure, a gap is provided between the falling guide plate (A) and the tip of the lower threaded rod (7) so that the workpiece (3) hits the falling guide plate (A) and falls. .

ることもできる。In addition, in the above embodiment, the case where there are two upper threaded rods and one lower threaded rod is shown, but depending on the diameter and shape of the workpiece (3) (it does not necessarily have to be circular), it is possible to use two lower threaded rods. It can also be a book or more. Also, work (3)
It is also possible to prepare various threaded rods with different root widths depending on the thickness of the threaded rod, and to replace the threaded rods as necessary.
その他、特許請求の範囲に記載した本発明の要旨を逸脱
しない限り、種々の変形・変更をしうろことはいうまで
もない。It goes without saying that various other modifications and changes may be made without departing from the gist of the present invention as set forth in the claims.

皆無である。また、接触によって放電したり傷が付いた
りしない。As explained above, according to the present invention, the drawbacks of the conventional system can be wiped out. In other words, (c) no welding occurs between the workpieces. In the present invention, the workpieces move without contacting each other at all, so there is no welding of the workpieces together. Also, it will not discharge or be scratched by contact.
（ロ） ワークは均等に加熱される。ワークは回転しな
がら移動するので、均熱効果がよく温度むらを生じない
。ただし、ワークが完全な円形でない場合は円滑な回転
はしないが、従来方式より均熱効果はよい。(b) The workpiece is heated evenly. Since the workpiece moves while rotating, the heating effect is good and temperature unevenness does not occur. However, if the workpiece is not perfectly circular, it will not rotate smoothly, but the heating effect will be better than the conventional method.
（ハ）加熱効率は良好である。(c) Heating efficiency is good.
に） ワークコイル内に多数のワークを収容しうる。) A large number of workpieces can be accommodated within the workpiece coil.
個々のワークはねじ棒に挾まれた形で進行するねじの谷
部に沿って移動するので、ワークの整列が乱れることは
ない。Since each workpiece moves along the trough of the advancing screw while being held by the threaded rod, the alignment of the workpieces is not disturbed.
