た。In Japanese Patent Application No. 61-67883, the applicant of the present invention proposed a microwave heating device that can heat a polymeric material such as rubber to a predetermined temperature in a narrow area in an extrusion molding machine in an extremely short period of time. We proposed a device as shown in Figure 4.

る。Reference numeral 1 denotes a mechanism for extruding a polymer material, and a cylinder 2 has a built-in screw 3 for extrusion. The head portion of the extrusion mechanism section 1 has a molding die 4 and a space 5 that becomes a microwave heating zone, and a polymer material passes between the microwave heating zone 5 and the extrusion mechanism section 1. It is partitioned off by a microwave shielding plate 7 having a plurality of small holes 6 . Furthermore, the microwave heating zone 5 and the microwave introduction path 8 are separated by a pressure partition 9.

はない。The raw polymeric material is transferred to the head section by the extrusion mechanism l, and is passed through the small holes 6 of the microwave shielding plate 7.
- is pushed out into the microwave heating zone 5. Since the microwave heating zone 5 is supplied with microwaves from the microwave introduction path 8, the polymer material in the microwave heating zone 5 is extruded from the molding die 4 after being heated by the microwave. , molded. Note that since the microwave introduction path 8 and the microwave heating zone 5 are separated by a pressure partition 9, the microwave heating zone 5
The polymer material inside does not enter the microwave introduction path 8.

。By the way, the raw material (polymer material) is
If there is variation in the amount of water supplied to the microwave heating zone 5, there will be variation in the heating rate. Mechanisms for extruding the raw material include a structure in which the raw material is continuously extruded using a screw 3 or the like as shown in the figure, and a mechanism in which the raw material is extruded intermittently using a plunger or the like. In the case of a continuous type, the supply amount varies depending on the rotational speed of the screw 3, the density of the raw material, etc.
間欠式の場合は、プランジャーを駆動する流体圧シリン
ダ等の速度によって供給量が変動する。In the case of an intermittent type, the supply amount varies depending on the speed of the fluid pressure cylinder etc. that drives the plunger.

。そして１５０℃程度の温度でノズル１３から型１１中
に射出され、１７０℃程度に保持されている型ｌｌ中で
成型される。FIG. 5 shows an example in which raw materials are intermittently supplied to a mold 11 for molding via a microwave heating zone 5 using a plunger 10 for molding. The temperature of the raw material in the cylinder 12 containing the plunger 10 is normally set at 90 to 110°C, and is further heated to about 50°C in the microwave heating zone 5. Then, it is injected into the mold 11 from the nozzle 13 at a temperature of about 150°C, and molded in the mold 11 maintained at about 170°C.

と、８０秒程度で粘度が充分上昇するが、更に１０℃程
度高くして１５０℃程度に加熱すると、半分の４０秒程
度で粘度が充分上昇する。FIG. 6 is a characteristic diagram showing the relationship between heating temperature, raw material viscosity, and curing time in the microwave heating zone 5. As shown by the broken line curve, when heated to a temperature of about 140°C, the viscosity increases sufficiently in about 80 seconds, but when heated further by about 10°C to about 150°C, the viscosity increases by half, in about 40 seconds. rises sufficiently.
加熱温度を更に上げると、粘度上昇所要時間は更に短縮
されるが、粘度上昇が速すぎて、ノズル１３中で硬化し
てしまう。If the heating temperature is further increased, the time required to increase the viscosity is further shortened, but the viscosity increases too quickly and hardens in the nozzle 13.
このようにマイクロ波加熱ゾーン５における加熱温度が
異なると原料の硬化時間が異なり、型１１で射出成型す

。ところが前記のように、原料供給量が一定しないと、
原料の所定体積当たりのマイクロ波パワーが一定しない
ため、加熱温度にバラツキが生じ、原料の硬化時間に変
動が生じることになる。As described above, if the heating temperature in the microwave heating zone 5 differs, the curing time of the raw material differs, and when injection molding is performed using the mold 11, it becomes difficult to repeat molding at a constant cycle. However, as mentioned above, if the amount of raw materials supplied is not constant,
Since the microwave power per predetermined volume of the raw material is not constant, the heating temperature varies and the curing time of the raw material varies.
また間欠供給の場合、型１１に原料を充填完了すると、

げつきが発生する。In the case of intermittent supply, once the mold 11 is filled with raw materials,
Microwave heating is interrupted after a predetermined time by a timer, but if there is variation in the supply speed by the plunger 10 and the microwave continues to be applied even after filling is completed, the raw material may be heated in the microwave heating zone 5. There is a risk of burning and clogging. Alternatively, if the raw material is clogged with foreign matter, the raw material will continue to be heated until the time set by the timer has elapsed, resulting in burnt material.
このような問題は、加熱源として高周波加熱や通常のヒ

本発明の技術的課題は、従来の高分子原料の加熱装置に

Detects movement. 15 is a control means, and the detector 14
The output power of the heating means 16 is controlled by the detection signal from the heating means 16. The polymer raw material supplied to the heating zone 5 by the plunger 10 or the like is heated by a heating means 16 such as a microwave generator or a high frequency heating device.

パワーは一定となり、常時一定の温度に加熱される。The raw material in the cylinder 12 is transferred to the molding section 1 via the heating zone 5 by the plunger 10 of the extrusion mechanism section 1.
Pushed out to 1. The heating zone 5 is heated by the heating means 16, and the output power of the heating means 16 is controlled by the control means 15 to which the detection signal from the detector 14 is input. That is, when the speed of the raw material passing through the heating zone 5 by the extrusion mechanism section 1 is high, the heating means 16
If the output power of the heating means 16 increases and conversely becomes slow, the output power of the heating means 16 decreases. As a result, even if the speed of the raw material passing through the heating zone 5 changes, the heating power per unit volume of the raw material remains constant, and the raw material is always heated to a constant temperature.

加熱ゾーン５が加熱過剰を招（恐れはない。Furthermore, when the raw material fills the molding section 11, the extrusion mechanism section 1
Since the extrusion operation of the heating means 16 is stopped, the control means 15 turns off the output power of the heating means 16 in response to the detection signal from the detector 14. Therefore, the raw material stopped in the heating zone 5 will not be heated and burnt. Even if the raw material stops in the heating zone 5 due to clogging with foreign matter, the output of the heating means 16 is turned off,
Heating zone 5 may lead to overheating (there is no danger of this).

FIG. 2 is a sectional view showing an embodiment of the heating control device according to the present invention. A hydraulic cylinder 17 is provided for driving the plunger 10 and its piston rod 18 is connected to the plunger 10.

The piston 19 is driven to reciprocate by alternately supplying and discharging the fluid to the head cover side and the rod cover side.

供給される。When the plunger 10 retreats, raw material is sucked into the cylinder 12 from the raw material supply pipe 22, and when the plunger 10 moves forward, the raw material in the cylinder 12 is supplied to the molding section 11 via the heating zone 5 and the nozzle 13.

クロ波発生器１６に接続されている。The microwave generator 16 is connected via a waveguide 23 to the pressure bulkhead 9 of the microwave heating zone 5 . 24
is a filler. A detector 14 such as a pulse encoder is connected to the piston rod 18 via a rack and pinion, and the detector 14 is connected to a microwave generator 16 via a proportional controller 15.

イクロ波発生器１６からの出力パワーが減少するように
制御される。Therefore, the moving speed of the plunger 10, that is, the moving speed of the raw material in the heating zone 5, can be detected by the detection signal from the detector 14, and the microwave generator 16 is controlled by the proportional controller 15 to which this detection signal is input. Ru. That is, when the moving speed of the plunger 10 is fast, the output power from the microwave generator 16 increases, and when the moving speed of the plunger 10 is slow, the output power from the microwave generator 16 is decreased.
また成型部１１が充満すると、プランジャー１０は停止
するため、マイクロ波発生器１６の出力パワーがオフと
なるように制御され、停止時の原料が加熱されるのを防
止している。Furthermore, when the molding section 11 is filled, the plunger 10 stops, and therefore the output power of the microwave generator 16 is controlled to be turned off, thereby preventing the raw material from being heated when the molding section 11 is stopped.

クロ波発生器１６に入力する。FIG. 3 is a block diagram showing an example of the proportional controller 15, and is applied when the detector 14 and the microwave output setting device are of digital type. When the detector 14 outputs a digital detection signal, such as a pulse encoder, the proportional controller 15 is provided with an f/V (frequency/voltage) converter 25 in the detection signal output section, and its output signal is is output to the microwave generator 16 via the multiplier 26. On the other hand, a digital switch 27 is used as a setting device for setting the microwave output power per unit volume, and its output signal is transmitted via a D/A converter 28.
It is input to the other input terminal of the multiplier 26. As a result, the value set by the digital switch 27 and the value detected by the detector 14 are multiplied and inputted to the microwave generator 16 as a reference output.

The temperature of the polymer raw material passing through can be maintained constant at all times. As a result, the curing time of the polymer raw material can be controlled at a constant level, and operations such as molding can be performed stably at a constant cycle. In addition, if the molding section is filled with polymer raw materials or clogged with foreign matter and the polymer raw materials cannot be moved, the output of the heating means 16 will be turned off by the detection signal of the detector, which will prevent the polymer raw materials from burning. etc. will be prevented.
