停止する。 PROBLEM TO BE SOLVED: To provide an apparatus capable of heating and fusing thermoplastics reliably and with high quality. SOLUTION: Infrared rays from a halogen lamp 22 are irradiated to a bonding portion 13 of plastics 11 and 12 via a chopper 30 to heat. The infrared temperature from the bonding portion 13 is reflected by the reflection portion of the chopper 30 and detected by the sensor 25, thereby detecting the radiation temperature of the bonding portion 13. When the bonding portion 13 melts, the temperature rise stops due to the latent heat.
Numeral 29 detects the melting of the bonding portion 13 by monitoring the time change of the radiation temperature. When the melting is detected, the power supply circuit 21 of the halogen lamp 22 is controlled to stop the infrared irradiation.

In particular, polyethylene is not only strong but also flexible, so that water is buried underground in earthquake-prone areas. It is the most suitable material for pipes and gas pipes. However, the polyethylene pipe has a problem in a method of joining the pipes when the pipe is extended. In the case of a vinyl chloride tube, simple joining using an adhesive is possible, but in the case of a polyethylene tube, since there is no adhesive, there is no effective joining method other than bonding by heating and melting.

EF that generates Joule heat and heats and melts the surroundings by heat conduction to join the tubes
(Electrofusion) method. In the EF method, as a method for judging that the fusion has been completed, there are a method using a special pipe joint in which a temperature sensor for detecting a heating temperature is embedded, and a special pipe having a pin structure which floats by the pressure of heating and melting. There are a method using a joint and a method of determining the energization time for each type of joint (diameter, shape, etc.).

（口径、形状など）毎に決めておく方法によっている。[0004] As another joining method, there is a butt fusion method in which a joining surface of two pipes to be joined is melted by a heating plate, the heating plate is removed, and the two tubes are pressurized and joined. In the butt fusion method, the completion of fusion is determined in advance for each pipe by a pressing force, a pressurizing time, and the like. Also, a method using microwave heating has been studied. In this case, since polyethylene does not absorb microwaves, it is well compatible with polyethylene on the joint surface, and a material serving as a microwave absorber, for example, polyaniline, is added at several tens%. When microwaves are applied to this, the portion containing polyaniline absorbs the microwaves and is heated, so that the surroundings can be heated and melted to join the tubes. Also in this case, as a method of judging that the fusion is completed, the energization time is determined for each type of joint (diameter, shape, etc.).

を生じる場合がある。In the EF method, foreign matters remain in the polyethylene and the current tends to increase in order to shorten the fusing time. This tends to cause deterioration of the resin due to overheating, which tends to reduce the strength of the joint. Also,
In the method of judging the completion of fusion using a special pipe joint that embeds the temperature sensor as described above or has a pin structure that floats by the pressure of heating and melting, a part of the place to be fused is used. , It is not known whether the fusion was successfully performed in other parts. Furthermore, the method of completing the fusion by controlling the current supply time does not directly detect the molten state of the polyethylene and confirm that the bonded portion has been fused, and does not terminate the current supply.

きないという問題点がある。In the butt fusion method or the method using microwave heating, these methods directly detect the molten state of polyethylene, confirm that the bonded portion has been fused, and terminate the energization. However, there is a problem that the quality of the joint of the polyethylene pipes cannot be ensured, for example, the resin is deteriorated by the overheating, or the unfused portion remains.

When the bonding portion between the thermoplastics is heated by the heating means, the temperature of the bonding portion increases almost linearly. However, when the temperature of the bonded portion rises and the plastic starts melting, the temperature rise of the bonded portion is suppressed by the latent heat even if the heating is continued. Therefore, the melting state of the bonded portion can be known by monitoring the gradient of the time change of the temperature of the bonded portion.

Then, when the melting of the bonded portion is detected, the heating is stopped, so that the bonded portion can be heated with high quality without deteriorating the bonding quality such as deterioration of the resin due to overheating and remaining unfused portions. The fusion can be completed. Also, since the temperature of the bonded part is measured in a non-contact manner by the radiation temperature measuring means,
There is no need for a special member such as a pipe joint in which a temperature sensor is embedded.

The infrared light from the halogen lamp 22 is reflected by the reflector 23
As a result, the light is focused on the bonding portion 13 of the plastics 11 and 12, and the bonding portion 13 is heated and melted. The radiation temperature measurement means
A reflector 24 for condensing infrared rays radiated from the bonding portion 13 onto a radiation temperature measurement sensor 25 such as a photodiode, a sensor circuit 26 for signal processing of an output detected by the sensor 25, an amplifier 27, an A / D converter 28.

Between them, a chopper 30 for intermittently irradiating the irradiation light from the halogen lamp 22 is provided. Chopper 30 is C
It is rotated by a motor 32 driven by a motor drive circuit 31 under the control of the PU 29. The chopper 30
As shown in the plan view of FIG. 3, it is composed of a transmission part 33 and a reflection part. The rotational position of the chopper 30 is detected by the photo interrupter 35.

ない。FIGS. 4 and 5 show how the heating of the bonding portion 13 of the plastics 11 and 12 and the measurement of the radiation temperature of the bonding portion 13 are performed alternately when the chopper 30 rotates. As shown in FIG. 4, when the transmission part of the chopper 30 is located in the optical path of the infrared irradiation light from the halogen lamp 22, the bonding part 13 is heated. At this time, since the infrared ray generated in the bonding portion 13 does not reach the sensor 25, the radiation temperature of the bonding portion 13 is not measured.

On the other hand, the bonding portion 13
The infrared rays generated from the light are reflected by the reflecting portion 34 of the chopper 30 and are incident on the sensor 25 by the reflector 24, so that the radiation temperature of the bonding portion 13 is measured. This measurement is performed by detecting the rotation of the chopper 30 with the photo interrupter 35.

捉えて接着部１３の溶融を検知する。FIG. 6 shows how the radiation temperature of the bonding portion 13, that is, the output of the sensor 25, changes with time when heating of the bonding portion 13 of the plastics 11 and 12 is continued by irradiating infrared rays from the halogen lamp 22. As shown, the output of the sensor 25 (radiation temperature of the bonding portion 13)
Increases almost linearly with the heating time.
When 3 starts melting, an increase in output (increase in radiation temperature) is suppressed by the latent heat at the time of melting. The CPU 29 compares the radiation temperature of the bonding portion 13 measured by the sensor 25 at regular time intervals, and detects the melting point of the bonding portion 13 by capturing the time when the gradient of the temporal change in the radiation temperature changes first.

The CPU 29 controls the power supply circuit 21 and controls the halogen lamp 2
The output is controlled by adjusting the power supply to 2. That is,
When the melting of the bonding portion 13 is detected, the heating is stopped. In addition, good melting becomes possible by controlling the output in accordance with the melting characteristics peculiar to each plastic (for example, the melting characteristics relating to the heating amount and time). The manner of melting of plastics depends on the difference in density, such as high-density polyethylene (HDPE) and medium-density polyethylene (MDPE), and the difference in color, such as transparency, white, and green. Taking HDPE and MDPE as an example, when heating with the same heat source and heating, MDPE has a higher temperature rise rate than HDPE. Therefore, when it is desired to dissolve HDPE quickly, the heat source output may be increased.
