Description
본 발명은 타이어용이나 기술적인 고무(Technical rubber)의 제조를 위한 고무를 배합하는 정련공정(Mixing room)에 있어서, 배합고무 시팅 및 배합용 밀의 표면의 온도를 제어할 수 있는 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system capable of controlling the temperature of the surface of a compounding rubber seating and compounding mill in a mixing room for compounding rubber for tires or for the manufacture of technical rubber.
보다 상세하게는 고무 배합용 믹서에서 배합완료 후 통상적으로 믹서 하단에 위치하여 배합물을 시팅(sheeting)하거나 추가적인 분산을 목적으로 배합할 때, 이용되는 밀(혹은 롤)의 표면 온도를 제어하는 시스템을 제공하는 데에 있다.More specifically, in a rubber compounding mixer, a system for controlling the surface temperature of the mill (or roll) used when the compounding is normally placed at the bottom of the mixer and sheeted or blended for further dispersing purposes. To provide.
종래 기술은 밀에서의 온도를 능동적으로 제어하는 것이 아니라, 단지 냉각수를 밀 내부로 통과시켜, 밀의 온도를 낮추도록 구성된다. The prior art is not configured to actively control the temperature in the mill, but is configured to only pass cooling water into the mill to lower the temperature of the mill.
도 1은 종래 기술의 밀을 냉각하는 배관도를 나타낸 것으로, 밀의 온도를 제어할 수 있는 수단은 없으며 밀(1,2) 내부로 냉각수만 유입되도록 구성되어 있다. Figure 1 shows a piping diagram for cooling the mill of the prior art, there is no means for controlling the temperature of the mill, it is configured so that only the coolant flows into the mill (1, 2).
따라서, 이를 위해 냉각수가 공급되는 공급관과, 배출되는 배출관을 가지며, 밀에 공급되는 냉각수의 유입양을 조절하기 위한 조절밸브(4,5)가 냉각수 공급관과 밀 사이에 설치된다. Therefore, for this purpose, the cooling pipe is provided between the cooling water supply pipe and the mill, which has a supply pipe to which the coolant is supplied and a discharge pipe to be discharged, and controls an inflow amount of the cooling water supplied to the mill.
도면부호 3은 밀에 의해 시팅된 배합고무시트이다.Reference numeral 3 is a compound rubber sheet seated by a mill.
도 1에 도시된 바와 같이 밀에서 배합된 고무의 시팅(혹은 추가적인 배합)작업을 할 때의 밀의 온도제어(결국은 밀 표면 온도제어)를 할 수 있는 수단이 없기 때문에 시팅되는 고무의 특성에 맞도록 밀 표면온도를 제대로 맞추어 줄 수 없다. As shown in Fig. 1, there is no means for temperature control of the mill when the sheeting (or additional compounding) of the rubber compounded in the mill (finally, the surface temperature of the mill). The surface temperature of the mill cannot be adjusted properly.
배합고무의 시팅시 고무배합물의 조성에 따라 밀에서의 가공성 및 밀 표면에서의 부착성 등과 같은 작업성에 차이가 발생된다. When the compounding rubber is seated, there is a difference in workability, such as workability in the mill and adhesion on the surface of the mill, depending on the composition of the rubber compound.
예를 들면, 합성고무 특히 부틸고무 배합물은 그 특성상 차가운 쪽이 밀에 달라붙는 경향이 있는데, 고무의 접촉시간의 더 짧은 관계로 표면이 더 차가운 뒤쪽 밀(2)에 달라붙게 된다.For example, synthetic rubber, in particular butyl rubber blends, by their nature tend to stick to the mill on the cold side, with the shorter contact time of the rubber causing the surface to stick to the colder mill 2.
상기와 같이 밀에서 고무 가공 중 배합고무시트의 진행방향과는 반대인 뒤쪽 밀(2)에 고무가 달라붙게 되면 작업자는 전체의 작업을 중단하고 다시 원래의 진행방향인 앞쪽 밀로 유도를 해주는 작업을 하여야 함에 따라 작업손실이나 유도작업시 고무가 이탈되어 바닥에 비산되면 원가손실 요인이 되기도 한다.As described above, when rubber adheres to the rear mill (2) opposite to the direction of travel of the compound rubber sheet in the rubber processing in the mill, the worker stops the whole work and guides the work back to the original direction in the front direction. Therefore, when the rubber is released and scattered on the floor during work loss or induction work, it can be a cost loss factor.
또한, 천연고무배합물이나 혹은 하나의 고무배합물에 이종고무가 많은 배합물이나 믹서에서 충분하게 처리가 안된 배합물에 대한 추가적인 배합을 밀에서 수행하기 위해서는 각각의 고무배합물의 조성에 맞추도록 밀 온도를 제어할 필요성이 있으나 종래의 장치로는 이러한 효과를 기대할 수가 없다.In addition, the mill temperature can be controlled to match the composition of each rubber compound in order to perform additional blending in the mill for natural rubber blends or blends that have not been sufficiently treated in one rubber blend or for blends that have not been sufficiently processed in a mixer. Although there is a need, conventional effects cannot be expected.
상기와 같이 종래의 단점을 극복하기 위하여 안출된 본 발명의 목적은, 각 고무배합물의 조성에 맞는 밀 표면온도를 적정하게 유지하여 줄 수 있도록 밀 표면온도를 제어할 수 있는 시스템을 제공하는 데에 있다. An object of the present invention devised to overcome the disadvantages of the prior art as described above, to provide a system that can control the surface temperature of the mill so as to properly maintain the mill surface temperature for each rubber compound composition have.
상기의 목적을 달성하기 위한 본 발명은, 2개의 밀에 각각 순환수를 공급하는 공급펌프와, 상기 공급펌프에 순환수를 소정의 온도로 유지시켜 공급하는 냉각용 열교환기와 가열용 열교환기와, 상기 밀을 통과한 순환수를 회수하여 냉각용 열교환기와 가열용 열교환기로 보내는 회수조를 가지는 순환부; 및 상기 냉각용 열교환기와 가열용 열교환기에 공급되는 냉각수와 스팀의 양을 조절하도록 각각에 설치된 제어밸브와, 상기 냉각용 열교환기와 가열용 열교환기에 의해 온도조절된 순환수의 온도를 측정하는 열전쌍과, 상기 밀 표면의 온도를 측정하는 온도센서와, 상기 제어밸브와 열전쌍과 온도제어부와 연결되어 온도데이타 수집 및 제어밸브를 조작하는 컨트롤러와, 상기 컨트롤러와 PLC를 통해 연결되어 설정온도를 부가하는 PC를 가지는 제어부를 포함하는 밀표면 온도 제어시스템이다. The present invention for achieving the above object is a supply pump for supplying circulating water to each of the two mills, a cooling heat exchanger and a heat exchanger for heating and maintaining the circulating water at a predetermined temperature to the supply pump, A circulation unit having a recovery tank for recovering the circulating water passing through the mill and sending it to the cooling heat exchanger and the heating heat exchanger; And a control valve installed to adjust the amounts of cooling water and steam supplied to the cooling heat exchanger and the heating heat exchanger, and a thermocouple measuring the temperature of the circulating water temperature controlled by the cooling heat exchanger and the heating heat exchanger. A temperature sensor for measuring the temperature of the surface of the mill, a controller connected to the control valve, a thermocouple, and a temperature control unit to operate temperature data collection and control valves, and a PC connected to the controller and a PLC to add a set temperature; The branch is a surface temperature control system including a control unit.
상기 온도센서는 적외선온도센서인 것을 특징으로 한다. The temperature sensor is characterized in that the infrared temperature sensor.
이하, 본 발명을 도면 및 실시예를 통하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings and examples.
본 발명은 크게 밀의 내부를 통과하는 순환수를 순환시키는 순환부와, 상기 순환수의 온도제어 및 밀의 표면온도측정을 위한 제어부로 구성된다.The present invention is composed of a circulation unit for circulating the circulating water largely passing through the interior of the mill, and a control unit for temperature control of the circulating water and measurement of surface temperature of the mill.
상기 순환부는 회수조와, 공급펌프와, 냉각용 열교환기와, 가열용 열교환기 및 이들을 연결하는 배관으로 구성된다. The circulation section includes a recovery tank, a supply pump, a cooling heat exchanger, a heating heat exchanger, and a pipe connecting them.
또한 상기 제어부는 냉각용 열교환기와 가열용 열교환기에 각각 연결된 제어밸브와, 순환수의 온도측정을 위한 열전쌍과, 밀의 표면온도를 측정하는 온도센서와, 사익 제어밸브와 열전쌍과 온도센서와 연결된 컨트롤러 및, 상기 컨트롤러와 PLC를 통해 연결된 PC를 포함한다.The control unit may include a control valve connected to each of the cooling heat exchanger and the heating heat exchanger, a thermocouple for measuring the temperature of the circulating water, a temperature sensor for measuring the surface temperature of the mill, a controller connected to the sound control valve, the thermocouple, and a temperature sensor; And a PC connected via the controller and the PLC.
도 2에 도시된 바와 같이 밀에서 배합고무의 가공 중에도 밀(1,2) 표면의 온도를 정확하게 측정할 수 있도록 적정한 위치에서 온도센서(10)을 설치하고 여기에서 측정된 값은 컨트롤러(16)으로 보낼 수 있도록 구성한다.As shown in FIG. 2, the temperature sensor 10 is installed at an appropriate position so that the temperature of the surfaces of the mills 1 and 2 can be accurately measured even during the processing of the compound rubber in the mill. Configure to send to.
상기 온도센서(10)는 회전운동하는 밀에 직적 접촉하여 온도를 측정하는 것은 곤란하므로, 적외선온도센서와 같이 리모트측정이 가능한 온도센서를 사용하는 것이 바람직하다.Since the temperature sensor 10 is difficult to measure the temperature by directly contacting the rotating mill, it is preferable to use a temperature sensor capable of remote measurement, such as an infrared temperature sensor.
밀(1,2)에서 가공되는 각 고무배합물의 조성에 따라 적정한 온도가 유지될 수 있도록 밀(1,2)로 공급되는 배관 상에 열교환기(13,14)를 각각 배치하고, 그 다음 위치에는 열전쌍(17)을 장착하여 여기에서 읽어들인 순환수의 온도 값을 역시 컨트롤러로 보내 제어밸브(15,16)의 개폐동작을 통해 밀(1,2) 내부로 유입되는 물의 온도를 조절하도록 한다. The heat exchangers 13 and 14 are disposed on the pipes supplied to the mills 1 and 2 so as to maintain an appropriate temperature according to the composition of each rubber compound processed in the mills 1 and 2, and then the positions It is equipped with a thermocouple 17 to send the temperature value of the circulating water read here to the controller to control the temperature of the water flowing into the mill (1, 2) through the opening and closing operation of the control valve (15, 16) .
따라서, 열교환기(14,14) 각각에 유입되는 열교환 매체는 스팀과 냉각수로써, 양자를 회수조(9)에서 공급되는 순환수와 열교환을 하여 원하는 온도의 순환수를 만든다.Therefore, the heat exchange medium flowing into each of the heat exchangers 14 and 14 is steam and cooling water, and both heat exchange with the circulating water supplied from the recovery tank 9 to produce circulating water of a desired temperature.
그리고, 온도가 조절된 순환수가 밀(1,2) 내부로의 유입이 잘 되도록 하기 위해 공급펌프(11,12)를 장착하였으며,이 공급펌프(11,12)의 힘에 의해 순환수는 밀 내부를 거친 다음 회수조(9)로 다시 유입되어 밀(1,2) 내부로 다시 순환되기 위한 준비를 하게 된다. In addition, the feed pumps 11 and 12 were installed in order to allow the temperature-controlled circulating water to flow into the mill 1 and 2 well, and the circulating water was pushed by the force of the feed pumps 11 and 12. After passing through the interior of the recovery tank (9) is prepared to be circulated back into the mill (1, 2).
계속해서 컨트롤러(18)는 믹서의 동작을 관장하는 혹은 밀을 포함하는 믹서하부의 장치를 관장하는 PLC(19)와 통신이 가능토록 연결되어 있으며, 그리고 이 PLC(19)와 상호 통신이 가능하며 이를 관장하는 기능을 가지며 적절하게 프로그램 처리되어 있는 믹서 제어용 PC(20)와 연결하여 각 고무배합물의 조정에 따라 순환수의 온도를 적절하게 설정하고 또 이 값으로 제어가 될 수 있도록 한다. Subsequently, the controller 18 is connected to communicate with a PLC 19 which controls the operation of the mixer or a device under the mixer including the mill, and can communicate with the PLC 19. This is connected to the mixer control PC (20), which has a function to manage this and is properly programmed, so that the temperature of the circulating water can be appropriately set and controlled to this value according to the adjustment of each rubber compound.
또한, 여기에 종래에는 불가능하였던 각각의 고무배합물에 냉각수의 온도를 입력을 PC(20) 상에서 실시하고 이 입력 값들이 PLC(19)를 경유하여 컨트롤러(18)에 도달되도록 하여, 상기 컨트롤러(18)를 통해서 제어밸브(15,16)의 개폐동작을 제어함으로써, 궁극적으로 각 고무배합물의 밀 작업시 온도조절이 가능하게 되도록 구성하였다. In addition, the temperature of the cooling water is input to each rubber compound, which has not been possible in the related art, on the PC 20, and these input values are reached by the controller 18 via the PLC 19. By controlling the opening and closing operation of the control valves (15, 16) through), ultimately configured to enable the temperature control during the milling operation of each rubber compound.
타이어 및 기술적인 고무 배합용 믹서에서 배합을 완료 후 배합고무의 시팅 및 가공작업시 서로 다른 각 고무 배합물의 시팅 및 가공을 용이하게 도와줌으로써 궁극적으로는 작업지연요소의 배제와 배합물의 품질을 향상시킬 수 있다.After the formulation is completed in the tire and technical rubber mixing mixer, it facilitates the seating and processing of each different rubber compounding during the seating and processing of the compounding rubber, thereby ultimately eliminating work delay factors and improving the quality of the compounding. Can be.
