That is, in the present embodiment, the load for the upper plate 30C2 can be increased as the supporting load on the work W (see the arrow U in FIG. 6). Therefore, when the work W is rotated and high frequency induction heating is performed, the roundness of the work can be improved.

本実施形態に係る高周波誘導加熱装置１は、具体的には、図１に示すように、前記搬送部１０は、前記ワーク支持体３０が搬送方向Ｃ１に互いに間隔を有して、前記回転かつ前記上下移動可能に複数取り付けられ、前記搬送部１０の移動によって前記搬送方向Ｃ１に移動する構成となっている。また、本実施形態に係る高周波誘導加熱装置１は、前記搬送部１０がループ状に配置され、かつ、前記ループ状に沿って周回移動するように構成されている。なお、本実施形態に係る高周波誘導加熱装置１は、ループ状に沿って周回移動できればその構成は特に限定されないため、説明を省略する。 Specifically, in the high-frequency induction heating device 1 according to the present embodiment, as shown in FIG. 1, the transport unit 10 has the work support 30 rotating and rotating in the transport direction C1 with a distance from each other. A plurality of the devices are attached so as to be movable up and down, and the device is configured to move in the transport direction C1 by the movement of the transport unit 10. Further, the high frequency induction heating device 1 according to the present embodiment is configured such that the transport unit 10 is arranged in a loop shape and orbits along the loop shape. The configuration of the high-frequency induction heating device 1 according to the present embodiment is not particularly limited as long as it can orbitally move along the loop shape, and thus the description thereof will be omitted.

また、本実施形態に係る高周波誘導加熱装置１は、ループ状に沿って周回移動する方向（すなわち搬送方向Ｃ１）に向かって順に、ワーク設置領域１００、高周波誘導加熱領域（加熱ユニット）２００、冷却領域（冷却ユニット）３００、ワーク取出領域４００及びワーク支持部戻し領域５００を有している。 Further, in the high frequency induction heating device 1 according to the present embodiment, the work installation region 100, the high frequency induction heating region (heating unit) 200, and cooling are sequentially performed in the direction of orbiting along the loop shape (that is, the transport direction C1). It has a region (cooling unit) 300, a work removal region 400, and a work support return region 500.

ワーク設置領域１００では、ワーク支持体３０にワークＷを取り付ける。その取付方法としては、ワーク支持部戻し領域５００を通って戻され、ワーク設置領域１００に入ったワーク支持部３０（図４参照）に対して、ワーク支持部３０の上面チャック部３０Ｂ１を上昇させる（図５参照）。その上昇させた上面チャック部３０Ｂ１と下面チャック部３０Ａ１との間にワークＷ１をセットする（図６参照）。次に、ワークＷ１をセットした状態でワーク支持体３０が高周波誘導加熱領域（加熱ユニット）２００に入り、加熱体（加熱コイル）２０ＡによりワークＷ１が高周波誘導加熱される（図７参照）。次に、高周波誘導加熱されたワークＷ１が冷却領域（冷却ユニット）３００に入り、冷却体（冷却ジャケット４０Ａ）によりワークＷ１が冷却される（図８参照）。次に、冷却されたワークＷ１がワーク取出領域４００に入り、上面チャック部３０Ｂ１を上昇させることで、前記冷却されたワークＷ１をワーク支持体３０から取り出す。ワークＷ１が取り出されたワーク支持体３０は、ワーク支持部戻し領域５００を通って、再度、ワーク設置領域１００に周回移動される。 In the work installation area 100, the work W is attached to the work support 30. As a mounting method, the upper surface chuck portion 30B1 of the work support portion 30 is raised with respect to the work support portion 30 (see FIG. 4) that has been returned through the work support portion return region 500 and has entered the work installation region 100. (See FIG. 5). The work W1 is set between the raised upper surface chuck portion 30B1 and the lower surface chuck portion 30A1 (see FIG. 6). Next, the work support 30 enters the high frequency induction heating region (heating unit) 200 with the work W1 set, and the work W1 is high frequency induction heated by the heating body (heating coil) 20A (see FIG. 7). Next, the high-frequency induction-heated work W1 enters the cooling region (cooling unit) 300, and the work W1 is cooled by the cooling body (cooling jacket 40A) (see FIG. 8). Next, the cooled work W1 enters the work take-out area 400, and the upper surface chuck portion 30B1 is raised to take out the cooled work W1 from the work support 30. The work support 30 from which the work W1 has been taken out is recirculated to the work installation area 100 through the work support portion return area 500.

すなわち、本実施形態に係る高周波誘導加熱装置１は、前記ワークを冷却する冷却ユニット４０を更に備え、前記搬送部１０がループ状に配置され、かつ前記ループ状に沿って周回移動し、前記ワーク支持体３０が前記加熱ユニット２０を通過後、前記冷却ユニット３０を通過するように構成され、前記加熱ユニット２０及び前記冷却ユニット４０は、前記周回移動する搬送区間の一部である。
従って、本実施形態に係る高周波誘導加熱装置１は、高周波誘導加熱における焼き戻し処理にも適用することができる。 That is, the high-frequency induction heating device 1 according to the present embodiment further includes a cooling unit 40 for cooling the work, the transport unit 10 is arranged in a loop shape, and the work is orbiting along the loop shape. The support 30 is configured to pass through the cooling unit 30 after passing through the heating unit 20, and the heating unit 20 and the cooling unit 40 are a part of the orbiting transport section.
Therefore, the high frequency induction heating device 1 according to the present embodiment can also be applied to the tempering process in the high frequency induction heating.

図９は、図２の好ましいワーク支持部３０を示す側面概念図である。
前記荷重増加部３０Ｃは、図９に示すように、前記上面支持体３０Ｂに取り付けられた重り設置部３０Ｄを更に備えることが好ましい。
本実施形態に係る高周波誘導加熱装置１では、重り設置部３０Ｄは、前記上面支持体３０Ｂの上板３０Ｃ２の上面３０Ｄである。 FIG. 9 is a side conceptual diagram showing a preferable work support portion 30 of FIG.
As shown in FIG. 9, the load increasing portion 30C preferably further includes a weight mounting portion 30D attached to the upper surface support 30B.
In the high frequency induction heating device 1 according to the present embodiment, the weight installation portion 30D is the upper surface 30D of the upper plate 30C2 of the upper surface support 30B.

図９に示すように、重り設置部３０Ｄに、重りＷＢを積載することで、ワークＷへの支持荷重としてより増加させることができる（図９中矢印Ｕ参考）。これにより、ワークＷを回転させて高周波誘導加熱する際、ワークＷの真円度等を更に向上させることができる。
また、前記重りＷＢを上板３０Ｃ２の上面３０Ｄに積載する際、重りＷＢが落下しないように、前記上面３０Ｄに固定する固定手段を設けることが好ましい。 As shown in FIG. 9, by loading the weight WB on the weight installation portion 30D, the support load on the work W can be further increased (see the arrow U in FIG. 9). Thereby, when the work W is rotated and high frequency induction heating is performed, the roundness of the work W can be further improved.
Further, when the weight WB is loaded on the upper surface 30D of the upper plate 30C2, it is preferable to provide a fixing means for fixing the weight WB to the upper surface 30D so that the weight WB does not fall.
