Abstract

PURPOSE:To deliver an object to be heated at a specified temp. in an induction heater which heats the object to be heated while transferring the same by providing an arithmetic control device which detects the temp. of the object to be heated and corrects an input to a heating coil in the heating terminal region. CONSTITUTION:Plural heating coils 2, 3 are provided to a conveyor which transfers an oeject to be heated, and the coil 3 disposed in the terminal heating region is connected to an electric power source 4 to be used exclusively. An arithmetic control circuit 5 which detects the temp. of the object to be heated in the coil 3 to correct the input to the coil 3 in such a way that the temp. of the object to be heated attains a specified value is connected to the power source 4. The object to be heated is thus delivered out at a specified temp. from the heater, whereby the defective heating is decreased and the operating efficiency is improved.

という欠点があった。In an induction heating device that heats an object while transferring it, a plurality of induction heating coils are generally provided, and the coil heats the object up to 1'uil with a constant input, then stops the object or keeps it warm while transferring it at a low speed. In particular, attempts were made to shorten the temperature rise time, but this structure has the disadvantage that it is difficult to send the heated object from the heating device at a constant temperature because the temperature drops when the device is stopped or transferred at low speed. was there.

の入力を補正する演算、制御回路５が接続されている。FIG. 1 shows an induction heating device according to the present invention. In the heating device shown in this figure, a plurality of induction heating coils 2.8 are provided on a conveying device 1 for transferring a heated object, and a coil 8 disposed in a heating termination area is connected to a dedicated power source 4. The power source 4 is provided with a coil 3 that detects the temperature of the heated body within the coil 3 so that the temperature of the heated body becomes a constant value.
An arithmetic and control circuit 5 for correcting the input is connected thereto.

るという効果が得られる。When the object to be heated is heated while being transferred by the heating device, the temperature of the object to be heated increases as it moves through the heating regions H, , H, which are heated by the coils 263 connected to the power sources 6 and 4, respectively. Like the curve shown in Figure 2.
rise By correcting the input to whether to stop the heated object midway, it is possible to raise the temperature of the heated object to be processed to a certain value in the heating region H3.As described above, the present invention According to an induction heating device that heats a heated object while transferring it, the heating coil in the heating termination area is equipped with a deduction and control circuit that detects the temperature of the heated object and corrects human power, so that heating The object to be heated can be sent out from the device at a constant temperature, thereby achieving the effect that temperature rise failures can be reduced and operational efficiency can be improved.
