Description
본 고안은 타이어 제조에 필요한 각종 배합고무를 혼합할 때 사용되는 혼합기에 관한 것으로, 특히 혼합중 챔버내의 온도를 일정하게 유지시키면서 원하는 시간동안 혼합이 이루어지도록 함으로써 혼합물의 품도 향상 및 안정화에 기여할 수 있도록 된 혼합온도 및 시간제어기능을 갖춘 혼합기에 관한 것이다.The present invention relates to a mixer used when mixing various compounding rubbers required for tire production, and in particular, it is possible to contribute to improving the quality and stabilization of the mixture by allowing the mixing to be performed for a desired time while maintaining a constant temperature in the chamber during mixing. To a mixer with a mixing temperature and time control function.
주지된 바와 같이 타이어는 충진제와 연화제, 가황제, 가황촉진제와 같은 고무배합제를 적정비율로 혼합한 배합고무를 압출, 압연, 성형, 가류 등의 일련의 공정을 순차적으로 거치면서 제조되게 되는 바, 이 같은 공정중 원료고무를 기타 약품과 혼합시키는 첫 번째 공정을 정련공정이라 하고, 이때 이들을 적절하게 혼합하기 위하여 내부혼합기(internal mixer)가 사용되고 있다.As is well known, tires are manufactured by sequentially carrying out a series of processes, such as extrusion, rolling, molding, and vulcanization, of a compounding rubber mixed with a rubber compound such as a filler, a softener, a vulcanizing agent, and a vulcanization accelerator in an appropriate ratio. In this process, the first step of mixing raw rubber with other chemicals is called refining, and an internal mixer is used to properly mix them.
한편 이 혼합기는 고무와 각종 배합제가 투입되어 혼합이 일어나는 공간인 체임버와, 상기 체임버 내부에 위치하여 회전되면서 원료를 분쇄 및 분산시키는 로터(回轉子:rotor), 혼합이 완료된 혼합물을 체임버 외부로 방출하는 드롭도어(drop door) 및, 각종 원료를 체임버 내부로 투입한 다음 통로를 차단하고 혼합중인 혼합물에 소정 압력을 가해줌으로써 원할한 혼합을 유도하는 램(ram)등을 구비하고 있다.On the other hand, this mixer is a chamber in which rubber and various compounding agents are injected, and a chamber in which the mixing takes place, a rotor which is located inside the chamber and rotates to crush and disperse raw materials, and discharges the mixed mixture to the outside of the chamber. A drop door, and a RAM for introducing various raw materials into the chamber and then blocking the passage and applying a predetermined pressure to the mixture being mixed to induce a smooth mixing.
그런데 이와 같은 종래의 혼합기는 체임버와 로터 및 드롭도어 각각에 관이나 구멍의 형태로 순환라인을 설치하고 이 순환라인으로 냉각수를 통과시키고, 각 구성부위를 전도체 금속으로 제조함으로써 혼합시 발생되는 열을 간접제어하는 통상적인 방법을 취하고 있다.However, such a conventional mixer installs a circulation line in the form of a tube or a hole in each of the chamber, the rotor, and the drop door, passes the cooling water through the circulation line, and manufactures each component part with a conductive metal to heat the heat generated during mixing. The usual method of indirect control is taken.
그러나 이와 같이 금속의 특성을 이용하여 냉각시키는 방식은 그 효율이 극히 한정되기 때문에, 혼합시 체임버내부의 온도가 급격하게 상승하게 되면 이에 즉각적인 대응이 불가능하여 특히 주변온도가 상대적으로 높은 하절기에는 방출온도가 약 160℃ 내지 200℃까지 상승되므로, 배합고무의 물성저하로 혼합고무의 질을 떨어뜨리게 되고 결과적으로 타이어의 품질을 저하시키는 하나의 요인이 된다는 문제가 있다,However, since the efficiency of the cooling method using the characteristics of the metal is extremely limited, if the temperature inside the chamber suddenly rises during mixing, it is not immediately possible to respond to it, especially in summer when the ambient temperature is relatively high. Since the temperature rises to about 160 ° C to 200 ° C, there is a problem that the quality of the mixed rubber is degraded due to the deterioration of the properties of the compounded rubber, and as a result, the quality of the tire is reduced.
또한, 기존에 사용되고 있던 혼합기는 로터가 미리 설정된 회전속도로 동일한 회전수로 회전되기 때문에 온도에 민감한 황이 다량함유된 혼합물이나 실리카혼합물과 같은 경우에는 효율적으로 혼합이 이루어지도록 제어하는 것이 매우 어려워 품도의 불안정과 저하를 가져오는 주원인이 되다.In addition, since the rotor is rotated at the same rotation speed at a predetermined rotation speed, it is very difficult to control the mixing to be efficient in the case of a mixture containing a lot of temperature-sensitive sulfur or a silica mixture. Become the main cause of instability and deterioration.
한편 최근에는 이를 해결하기 위하여 컴퓨터를 이용하여 혼합시 온도가 상승되면 이에 따라 로터의 회전속도를 단계적으로 조절하는 방법이 사용되고 있기는 하나, 이 같은 방법은 혼합물별로 수십번씩 혼합을 실시하여 각각의 활성화에너지를 구해야 한다는 번거러움과 구해진 활성화에너지값을 컴퓨터에 수시로 입력해야 한다는 불편이 있다.Recently, in order to solve this problem, when the temperature is increased during mixing using a computer, a method of gradually adjusting the rotational speed of the rotor has been used. However, such a method is performed by mixing several times for each mixture to activate each. The inconvenience of finding the energy and the inconvenience of having to input the obtained activation energy value into the computer from time to time.
이에 본 고안은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로, 공지의 혼합기에 피.아이.디제어기(P.I.D controler : Proportional, Integral, Derivative)를 전기적으로 연결설치하여 혼합믹서내의 DC모우터에 의하여 작동되는 로터의 회전속도를 설정 단위시간별로 자동조절하여 고무와 배합제가 원하는 온도에서 소정 시간동안에만 혼합되도록 함으로써, 혼합이 균일하게 이루어지면서 혼합이 완료된 혼합물의 물성이 최적화되도록 된 혼합시간 제어기능을 갖춘 혼합기를 제공함에 그 목적이 있다.Therefore, the present invention has been devised to solve the above problems, and the P.I.D controller (PID controler: Proportional, Integral, Derivative) is electrically connected to and installed in a DC mixer in the mixer. By controlling the rotational speed of the rotor operated by unit time, the rubber and the compounding agent are mixed only for a predetermined time at a desired temperature, so that the mixing is made uniform and the properties of the mixed mixture are optimized. The purpose is to provide a mixer equipped with.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 혼합기의 개략단면도로써, 본 고안은 도면에 도시된 바와 같이 몸체(1)내에 배합될 고무가 채워지는 체임버(2)가 설치되면서 이 체임버(2)상부에 수직방향으로 고무와 배합제 투입에 사용되는 램(3)이 배치되고, 이 램(3)의 아래쪽에는 상호 역방향으로 회전되면서 체임버(2)내로 투입된 고무와 배합제를 서로 혼합시키게 되는 1쌍의 로터(4)가 위치하며, 상기 몸체(1)의 하부 즉 체임버(2)의 아래쪽에는 배합이 완료된 고무를 인출할 때 사용되는 드롭도어(5)가 설치된 혼합기(6)가 구비되는 한편, 상기 체임버(2)의 하부에는 PID제어기(7)와 전기적으로 연결된 열전도쌍(8)이 설치되어 있다.1 is a schematic cross-sectional view of a mixer according to the present invention, the present invention is installed in the vertical direction on top of the chamber (2) while the chamber (2) is filled with rubber to be blended in the body (1) as shown in the figure A ram 3 used to inject rubber and a compounding agent is disposed, and a pair of rotors 4 are disposed below the ram 3 to rotate together with each other to mix the rubber and the compounding agent introduced into the chamber 2 with each other. Is located, and the lower part of the body 1, that is, the lower part of the chamber 2, is provided with a mixer 6 provided with a drop door 5, which is used to take out the rubber having been blended, while the chamber 2 At the bottom of the), a heat conduction pair 8 electrically connected to the PID controller 7 is provided.
그리고 상기 PID제어기(7)는 도 2에 도시된 블록다이어그램에 나타난 바와 같이, 로터(4)를 구동하는 직류모우터(9)와 열전도쌍(8) 및 전원공급원(10)과 연결선(11)을 매개로 전기적으로 연결되어, 상기 직류모우터(9)로 공급하는 전류의 양을 조절함으로써 구동축(12)의 회전속도를 가감하여 로터(4)의 회전수를 제어하도록 구성되어 있다.As shown in the block diagram of FIG. 2, the PID controller 7 includes a DC motor 9, a heat conduction pair 8, a power supply source 10, and a connection line 11 that drive the rotor 4. It is electrically connected via a, it is configured to control the rotational speed of the rotor 4 by adjusting the amount of current supplied to the DC motor (9) by adjusting the amount of rotation.
이하 본 고안의 작동을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 따른 혼합기는, PID제어기(7)를 이용하여 각각의 혼합물별로 1회의 혼합만 실시하게 되면 혼합물의 온도를 제어, 안정 및 유지시키는데에 필요한 예컨대 비례상수나 적분상수와 같은 각종 기준치를 자동으로 구하고 이를 파일형태로 저장하여 해당되는 혼합작업시 간단한 조작만으로 각각의 기준치를 블러내 작업을 손쉽게 수행하도록 되어 있고, 또한 상기와 같은 자동선정방식으로 동작되는 PID제어기(7)를 통해 혼합기(6)의 로터(4)를 구동하는 직류모우터(9)에 연결되어 모우터의 회전속도를 배합물의 온도에 따라 반복적으로 감속 또는 증속시키면서 온도를 안정적으로 유지시킬 수 있도록 되어 있다.Mixer according to the present invention, if only one mixing for each mixture using the PID controller (7), the various reference values such as proportional constant or integral constant necessary for controlling, stabilizing and maintaining the temperature of the mixture automatically It is possible to easily carry out the work by blurring the respective reference values only by simple operation during the corresponding mixing operation by storing them in a file form, and also through the PID controller 7 operated by the automatic selection method as described above. It is connected to a direct current motor (9) for driving the rotor 4 of the) is to be able to maintain a stable temperature while repeatedly reducing or increasing the rotational speed of the motor according to the temperature of the compound.
즉, 상기 램(3)을 상부로 이동시켜 재료를 투입하고 다시 램(3)을 원위치시킨 다음 로터(4)를 회전시켜 배합작업을 실시하게 되며, 이후 상기 드롭도어(5)를 통해 배합이 완료된 고무를 외부로 인출하게 되는데, 배합이 진행되는 동안 상기 열전도쌍(8)을 매개로 혼합물의 온도를 측정하게 되고, 이 같이 측정된 온도를 PID제어기(7)로 전달하여 설정된 온도와 측정된 온도를 비교하여 로터(4)의 회전속도를 조절함으로써 체임버(1)내의 혼합물의 온도를 일정하게 유지시키면서 균일한 배합을 유도하게 되며, 상기 PID제어기(7)가 체임버(2)내의 혼합물의 온도를 일정하게 유지시키는 역할을 수행하는 동안 혼합기(6)가 최적 방출조건에 도달하게 되면 드롭도어(5)를 통해 혼합물을 방출하게 된다.That is, the ram 3 is moved to the upper part to inject the material, the ram 3 is returned to its original position, and the rotor 4 is rotated to perform the blending operation. Then, the blend is performed through the drop door 5. The finished rubber is taken out to the outside, and the temperature of the mixture is measured through the heat conduction pair 8 during the mixing process, and the measured temperature is transferred to the PID controller 7 to measure the set temperature. By comparing the temperature and adjusting the rotational speed of the rotor (4) to maintain a constant temperature of the mixture in the chamber (1) to induce uniform mixing, the PID controller (7) is the temperature of the mixture in the chamber (2) When the mixer 6 reaches the optimum discharge condition while maintaining the constant, the mixture is discharged through the drop door 5.
따라서 혼합물의 온도제어를 보다 효율적으로 할 수 있게 되고, 특히 혼합되는 온도에 민감하게 반응하는 다량의 황이 함유된 벨트계 혼합물이나 다량의 실리카를 충진제로 사용하는 혼합물의 품도를 향상시키고 안정화를 시킬 수 있으며, 기존의 혼합기에 내장된 혼합조건 설정기능은 독립적으로 동일하게 작동되게 되므로 혼합물을 방출할 때 소요되는 시간이나 전력의 단독모드는 물론 시간과 전력 및 온도와 전력을 혼합한 조합모드로 동작할 수 있게 되므로 보다 고품질의 혼합물을 얻을 수 있다.Therefore, the temperature control of the mixture can be more efficiently controlled, and the quality of the belt-based mixture containing a large amount of sulfur or the mixture using a large amount of silica as a filler can be improved and stabilized. Since the mixing condition setting function built in the existing mixer is operated independently and independently, it operates in combination mode of mixing time, power, temperature and power as well as time required when releasing the mixture or power alone mode. This allows higher quality mixtures.
한편, 본 고안에 따른 열전도쌍(8)은 기존의 혼합기에 설치되어 있는 것을 그대로 사용할 수도 있고, 필요에 따라서는 체임버(2)내의 서로 다른 위치에 다수의 열전도쌍을 별도로 설치하여 검출기에 의해 1차 계측하고 검출기내의 연산장치에 의하여 얻어진 평균값을 2차로 PID제어기(7)로 전달하여 보다 정밀한 제어를 수행할 수 있도록 할 수 있다.On the other hand, the heat conduction pair 8 according to the present invention can be used as it is installed in the existing mixer, as needed, by installing a plurality of heat conduction pairs separately at different positions in the chamber (2) by the detector 1 The difference measurement and the average value obtained by the computing device in the detector can be secondarily transmitted to the PID controller 7 so that more precise control can be performed.
또한 본 고안에 따른 혼합온도 및 시간제어기능을 갖춘 혼합기는, 본 고안에서 예를 들어 설명한 타이어 제조공정에만 국한되지 않고, 예컨대 혼합시간에 따라 물성이 예민하게 변하는 혼합물을 배합하는 장치에 폭넓게 적용시켜 사용할 수 있슴은 물론이다.In addition, the mixer having a mixing temperature and time control function according to the present invention is not limited to the tire manufacturing process described for example in the present invention, and is widely applied to an apparatus for compounding a mixture whose physical properties change sensitively with the mixing time, for example. Of course you can use it.
이상 설명한 것과 같이 본 고안에 따르면, 공지의 혼합기에 PID제어기를 전기적으로 연결설치하여 혼합기내의 DC모우터에 의하여 작동되는 로터의 회전속도를 설정 단위시간별로 자동조절하여 고무와 배합제의 혼합온도를 자동으로 조절하여 줌으로써, 혼합이 균일하게 이루어지면서 혼합이 완료된 혼합물의 물성이 최적화되는 잇점이 있다.As described above, according to the present invention, the PID controller is electrically connected to and installed in a known mixer to automatically adjust the rotational speed of the rotor operated by the DC motor in the mixer by setting unit time to adjust the mixing temperature of the rubber and the compounding agent. By adjusting automatically, the mixing is made uniform, and the physical properties of the mixed mixture is optimized.
