ているので、直接高温にさらされることがない。 In FIGS. 1 and 2, reference numeral 1 denotes a tunnel-type drying oven with infrared panel heaters 2 mounted on both side walls. 6 is mounted below the drying oven 1 on a pair of guides 3 installed horizontally through the inside of the drying oven 1, and is driven by the conveyance chain 4 to move on the guides 3 at a desired speed. , or a carrier that performs a desired stepwise motion. A workpiece drive chain 5 installed in parallel with the conveyor chain 4 in the drying oven 1 and driven by a power source (not shown) is connected to a conveyor 7.
The sprocket 7 is engaged with the sprocket 7 which is horizontally pivoted on the lower box of the drying oven 1, so that the sprocket 7 is always rotated regardless of the position of the conveyor 7 in the drying oven 1. Hollow support cylinders 8 1 and 8 2 are arranged vertically in parallel from the lower box of the carrier 6, and the support cylinder 8
A box-shaped head box 12 is fixed to the upper part of 1 and 82 . Within the head box 12, roller sprockets 10 1 and 10 2 are fixed to positions corresponding to the support cylinders 8 1 and 8 2, respectively, and the roller shafts 9 1 and 9 2 , which are horizontally pivoted, are at the same height . It is installed in the same position. Sprockets (not shown) corresponding to the roller sprockets 10 1 and 10 2 are installed in the lower box of the conveyor 6, and one of the sprockets is connected to the sprocket 7 driven by the workpiece drive chain 5. It is fitted onto the shaft. A workpiece rotation chain 11 is hung between the two sprockets in the lower box and the roller sprockets 10 1 and 10 2 in the head box 12 . Therefore, the roller shafts 9 1 , 9 2
are rotated in the same direction. Note that since the workpiece rotation chain 11 passes through the hollow portions of the support tubes 8 1 and 8 2 , it is not directly exposed to high temperatures.

ても、塗装膜を万遍無く均一に焼付けることが出
来る。 Rollers 13 1 , 13 configured as above
When the inner circumferential surface 15' of the hollow disk-shaped workpiece 15 is inserted into the V-groove rings 14 1 , 14 2 of No. 2 and the workpiece 15 is suspended so as to bridge the rollers 13 1 , 1
3 and 2 are rotating in the same direction, and sufficient frictional force is acting between the inner circumferential surface 15' of the workpiece 15 and the V-groove rings 141 and 142 , so the workpiece 15 is rotated in the vertical plane. It rotates and does not fall over. Therefore, when a workpiece with a coating film formed on the entire surface is hung on this carrier 6 and the carrier 6 is transferred into the drying oven 1, even if the temperature distribution of the panel heater 2 is uneven, the coating film will be removed. Can be baked evenly and evenly.
また、ローラーと加工物との接触部は常に変つ
ているので、従来の如く、内周面の一部が不完全
な焼付けになることもない。 Further, since the contact area between the roller and the workpiece is constantly changing, there is no possibility that a part of the inner peripheral surface will be incompletely baked as in the conventional case.
本発明の焼付方法は加工物を搬送具へ着脱が容
易で、しかも内径寸法の異なる加工物に対しても
共通の搬送具を使用することが出来るという利点
がある。 The baking method of the present invention has the advantage that the workpiece can be easily attached to and removed from the conveyor, and a common conveyor can be used even for workpieces having different inner diameters.

の範囲内で適宜変形実施しうるものである。 Note that the present invention is not limited to the illustrated embodiment; for example, the distance between the rollers may be widened and the outer circumferential surface of a disc-shaped workpiece without a hollow portion may be placed on the V-groove ring of the roller from above. The invention may be modified as appropriate within the scope of the claims.
