Description

本発明は、ゴム状物を押し出しながら混練する二軸押出機を用いたゴム粘度の制御方法および混練装置に関するものである。   The present invention relates to a rubber viscosity control method and a kneading apparatus using a twin screw extruder for kneading while extruding a rubber-like material.

一般に、タイヤ業界においては、空気入りタイヤの製造に用いるゴム状物を混練するために、回転する一対のロータを備えた混練ミキサーを使用するとともに、このような混練ミキサーから排出されたゴム状物を、次工程での取扱いが容易となるような断面形状に押出し成形する押出機を使用している。ここで、前述のような混練ミキサーは混練効率が比較的低いため、所定の混練度に達するまでに長時間混練したり、あるいは繰り返し混練する必要がある。   Generally, in the tire industry, in order to knead a rubber-like material used for manufacturing a pneumatic tire, a kneading mixer having a pair of rotating rotors is used, and the rubber-like material discharged from such a kneading mixer. Is used to extrude into a cross-sectional shape that facilitates handling in the next step. Here, since the kneading mixer as described above has a relatively low kneading efficiency, it is necessary to knead for a long time or to repeatedly knead until a predetermined degree of kneading is reached.

このため、従来、この混練ミキサーの混練を補助しようと、前記押出機に混練機能を付与することが考えられ、スクリューを平行に２本以上有し、該スクリューによってゴム状物を移送している際に混練を行うようにした二軸（複軸）押出機が提案されている。   Therefore, conventionally, in order to assist the kneading of the kneading mixer, it is considered to give the extruder a kneading function, and there are two or more screws in parallel, and the rubber-like material is transferred by the screws. A twin screw (multi-screw) extruder has been proposed in which kneading is performed.

しかし、このような従来の二軸（複軸）押出機には、ゴム原材料の粘度バラツキの影響を受けやすく、粘度の安定したゴム状物が得られないという問題がある。粘度の安定したゴム状物を得ることは、押出しや圧延作業等の後工程において、寸法精度および品質均一性を確保するために必要であり、そこで、これまでは、ゴム状物の粘度を、主にスクリュー構成を変更することで制御を行っていた（例えば、ゴム状物の粘度を低下させたい時は練りセグメント（ニーディングディスク）数を増やす）。   However, such a conventional twin-screw (multi-screw) extruder has a problem that it is easily affected by the viscosity variation of the rubber raw material and a rubber-like product having a stable viscosity cannot be obtained. Obtaining a rubber-like product having a stable viscosity is necessary in order to ensure dimensional accuracy and quality uniformity in subsequent processes such as extrusion and rolling operations. Control was mainly performed by changing the screw configuration (for example, when it is desired to reduce the viscosity of the rubber-like material, the number of kneading segments (kneading disks) is increased).

また、特許文献１において、ゴム状物の粘度を制御するために、押出機の長手方向に複数個の投入口を離間して設け、複数個の投入口を適宜選択することで押出機内を混練対象物が通過する長さを変更して混練対象物を所望の粘度に調整する混練装置が提案されている。
特開２００３−１９０７５６号公報 Further, in Patent Document 1, in order to control the viscosity of the rubber-like material, a plurality of input ports are provided apart in the longitudinal direction of the extruder, and the inside of the extruder is kneaded by appropriately selecting the plurality of input ports. There has been proposed a kneading apparatus that adjusts the kneading target to a desired viscosity by changing the length through which the target passes.
JP 2003-190756 A

しかしながら、スクリュー構成を変更する方法は、スクリュー構成とゴム粘度の相関関係が複雑であり、また、スクリューの交換に多大な人手と時間を要し、迅速に粘度制御ができないという問題があった。   However, the method of changing the screw configuration has a problem that the correlation between the screw configuration and the rubber viscosity is complicated, and it takes a lot of manpower and time to replace the screw, and the viscosity cannot be controlled quickly.

また、特許文献１に記載の混練装置を用いる方法は、押出機の長手方向に複数個の投入口を有する特殊な押出機を必要とするため、コストがかかるという問題があった。   Moreover, the method using the kneading apparatus described in Patent Document 1 requires a special extruder having a plurality of inlets in the longitudinal direction of the extruder, and thus has a problem of cost.

本発明は、このような問題点に鑑みてなされたものであり、本発明の目的は、スクリューの交換の必要がなく迅速に粘度を制御でき、かつ特殊な押出機を用いることなく低コスト化を可能にするゴム粘度の制御方法および混練装置を提供することにある。   The present invention has been made in view of such problems, and an object of the present invention is to reduce the cost without using a special extruder, without having to replace the screw, and capable of quickly controlling the viscosity. It is an object of the present invention to provide a rubber viscosity control method and a kneading apparatus that enable the above.

上記目的を達成するため、本発明のゴム粘度の制御方法は、複軸押出機でゴムを混練し、混練されたゴムの粘度を測定し、その測定値に基づいて押出機に供給するゴムの量を調整することにより、前記ゴムの粘度を所定の値に制御することを特徴とする。   In order to achieve the above object, the rubber viscosity control method of the present invention is a method of kneading rubber with a double screw extruder, measuring the viscosity of the kneaded rubber, and controlling the rubber to be supplied to the extruder based on the measured value. The viscosity of the rubber is controlled to a predetermined value by adjusting the amount.

本発明は、前記ゴムの粘度を測定し、ゴムの粘度の目標値との差分から前記ゴムの供給量を調整することが好ましい。また、本発明は、前記複軸押出機が二軸押出機であることが好ましい。   In the present invention, it is preferable to measure the viscosity of the rubber and adjust the supply amount of the rubber from the difference from the target value of the viscosity of the rubber. In the present invention, the double screw extruder is preferably a twin screw extruder.

また、本発明の混練装置は、ゴムを押し出しながら混練する押出機と、押出機にゴムを供給する定量供給装置と、押出機から押し出された混練ゴムの粘度を測定する粘度測定装置とを備え、前記粘度測定装置により、前記押出機から押し出された混練ゴムの粘度をオンラインで測定して、その測定値を前記定量供給装置にフィードバックし、定量供給装置により、前記測定値に基づいて前記押出機に供給するゴムの量を調整することを特徴とする。   The kneading apparatus of the present invention includes an extruder for kneading while extruding rubber, a quantitative supply device for supplying rubber to the extruder, and a viscosity measuring device for measuring the viscosity of the kneaded rubber extruded from the extruder. The viscosity of the kneaded rubber extruded from the extruder is measured online by the viscosity measuring device, and the measured value is fed back to the quantitative supply device. The measured value is fed by the quantitative supply device based on the measured value. The amount of rubber supplied to the machine is adjusted.

本発明は、ゴム投入量と練りゴムの粘度との相関関係を利用し、練りゴムの粘度をオンラインで管理して練りゴムの供給量にフィードバックすることで、ゴム原材料の粘度バラツキの影響を受けない、常に安定した一定粘度の練りゴムを得ることができる。   The present invention uses the correlation between the amount of rubber input and the viscosity of the kneaded rubber, manages the viscosity of the kneaded rubber online, and feeds back to the amount of kneaded rubber, which is affected by variations in the viscosity of the rubber raw material. It is possible to obtain a kneaded rubber having a constant viscosity which is not always stable.

次に、本発明の実施の形態について図面を参照して説明する。本発明のゴム粘度の制御方法は、複軸押出機に投入するゴムの量と練りゴムの粘度との間に高い相関があることを、新たに見い出したことに基づいてなされたものである。   Next, embodiments of the present invention will be described with reference to the drawings. The rubber viscosity control method of the present invention has been made on the basis of newly found that there is a high correlation between the amount of rubber to be fed into the double screw extruder and the viscosity of the kneaded rubber.

図１は、ゴム投入量と練りゴムの粘度との相関関係を示す図であり、押出工程において、天然ゴムを主原料とするノンプロ練りのペレットゴム（加硫剤を含まないでゴム成分とゴム配合剤を混練したゴム）とプロ練り薬品（硫黄、その他）とを、定量供給機（ｋ−ｔｒｏｎ社製）により、二軸押出機（神戸製鋼製ＫＴＸ３０）へ投入する際に、二軸押出機の稼働条件（回転数２００ｒｐｍ、スクリュー構成一定、温度１８℃）に変更を加えず、ゴムの投入量を、投入量範囲６〜２０ｋｇ／ｈｒで変化させたときのゴム投入量（ｋｇ／ｈｒ）とゴム粘度（ｋＰａ）との関係を示している。   FIG. 1 is a diagram showing the correlation between the amount of rubber input and the viscosity of a kneaded rubber. In the extrusion process, non-pro kneaded pellet rubber (not containing a vulcanizing agent and a rubber component and a rubber) containing natural rubber as a main raw material. When a compounding agent (rubber kneaded) and professional kneading chemicals (sulfur, etc.) are fed into a twin screw extruder (Kobe Steel KTX30) by a quantitative feeder (made by K-tron), twin screw extrusion The amount of rubber input (kg / hr) when the input amount of rubber was changed in the input amount range of 6 to 20 kg / hr without changing the machine operating conditions (rotation speed 200 rpm, constant screw configuration, temperature 18 ° C.) ) And rubber viscosity (kPa).

図１に示すように、ゴムの投入量を６ｋｇ／ｈｒから２０ｋｇ／ｈｒへと増加させると、練りゴム粘度が約６７ｋＰａ（キロパスカル）から約７４ｋＰａへと増加し、ゴムの投入量を２０ｋｇ／ｈｒから６ｋｇ／ｈｒへと減少させると、練りゴム粘度が約７４ｋＰａから約６７ｋＰａへと減少するというように、投入量とゴム粘度との間に比例関係が存在する。   As shown in FIG. 1, when the input amount of rubber is increased from 6 kg / hr to 20 kg / hr, the kneaded rubber viscosity increases from about 67 kPa (kilopascal) to about 74 kPa, and the input amount of rubber is increased to 20 kg / hr. When decreasing from hr to 6 kg / hr, the kneaded rubber viscosity decreases from about 74 kPa to about 67 kPa, so that there is a proportional relationship between the input amount and the rubber viscosity.

本発明は、ゴム投入量と練りゴムの粘度との相関関係を利用し、ゴム投入量を制御することで練りゴムの粘度を制御するものである。以下、本発明の実施の形態を詳細に説明する。   The present invention utilizes the correlation between the amount of rubber input and the viscosity of the kneaded rubber, and controls the viscosity of the kneaded rubber by controlling the amount of rubber input. Hereinafter, embodiments of the present invention will be described in detail.

図２は、本発明において使用する二軸押出機を模式的に示す図である。図において、二軸押出機１１は側面からみた模式断面を示している。図２に示す混練装置は、天然ゴムを主原料とするノンプロ練りのペレットゴム（加硫剤を含まないでゴム成分とゴム配合剤を混練したゴム）とプロ練り薬品（硫黄、その他）とを押し出しながら混練する二軸押出機１１と、この二軸押出機１１に、ノンプロ練りのペレットゴムとプロ練り薬品とを供給する定量供給装置１２と、二軸押出機１１から押し出された練りゴムの粘度を測定する粘度測定装置（図示せず）とにより構成される。   FIG. 2 is a diagram schematically showing a twin-screw extruder used in the present invention. In the figure, the twin-screw extruder 11 shows a schematic cross section viewed from the side. The kneading apparatus shown in FIG. 2 contains non-pro kneaded pellet rubber (a rubber obtained by kneading a rubber component and a rubber compounding agent without using a vulcanizing agent) and a pro kneading chemical (sulfur, etc.). A twin-screw extruder 11 for kneading while extruding, a quantitative supply device 12 for supplying non-pro-kneaded pellet rubber and pro-kneading chemicals to the twin-screw extruder 11, and the kneaded rubber extruded from the twin-screw extruder 11 And a viscosity measuring device (not shown) for measuring the viscosity.

二軸押出機１１は、複数の練りセグメントが組み込まれた２本のスクリュー１３と、この２本のスクリュー１３が回転するための筒状の空洞部であるチャンバ１４を有するシリンダ１５とを備えている。２本のスクリュー１３は、図２中のスクリュー部の部分平面図に示すように、軸心同士が平行となって配置されている。この２本のスクリュー１３は、シリンダ１５の一端側に設けられた、図示しないモータおよび減速機を備える駆動部に連結され、同方向に回転駆動される。このシリンダ１５には、チャンバ１４内にノンプロ練りのペレットゴムとプロ練り薬品を受け入れる投入口１６が設けられている。   The twin-screw extruder 11 includes two screws 13 in which a plurality of kneading segments are incorporated, and a cylinder 15 having a chamber 14 that is a cylindrical cavity for the rotation of the two screws 13. Yes. As shown in the partial plan view of the screw portion in FIG. 2, the two screws 13 are arranged such that the shaft centers are parallel to each other. The two screws 13 are connected to a driving unit provided on one end side of the cylinder 15 and including a motor and a speed reducer (not shown), and are driven to rotate in the same direction. The cylinder 15 is provided with an inlet 16 for receiving non-pro-kneaded pellet rubber and pro-kneaded chemicals in the chamber 14.

次に、本実施形態に係るゴム粘度の制御方法について図２を用いて説明する。天然ゴムを主原料とするノンプロ練りのペレットゴムとプロ練り薬品とを、定量供給機１２により、二軸押出機１１の投入口１６へ投入すると、これらの投入口１６から定量供給装置１２によって供給されたノンプロ練りのペレットゴムとプロ練り薬品は、チャンバ１４内でスクリュー１３が回転することで、スクリュー１３とチャンバ１４の内壁との間に形成される空間で、一定のせん断エネルギーが加えられて混練が行われ、さらに図中右側に向かって軸方向に押出されることによって連続的に混練が行われる。そして、シリンダ１５の先端部１７は、大気開放となっており、この先端部１７から混練された練りゴム１８が排出される。   Next, a rubber viscosity control method according to this embodiment will be described with reference to FIG. When non-pro-kneaded pellet rubber and pro-kneaded chemicals, which are mainly made of natural rubber, are fed into the inlet 16 of the twin-screw extruder 11 by the quantitative feeder 12, they are supplied from the inlet 16 by the quantitative feeder 12. The non-pro-kneaded pellet rubber and the pro-kneading chemical are applied with a certain shearing energy in the space formed between the screw 13 and the inner wall of the chamber 14 as the screw 13 rotates in the chamber 14. The kneading is performed, and the kneading is continuously performed by extruding in the axial direction toward the right side in the figure. The tip portion 17 of the cylinder 15 is open to the atmosphere, and the kneaded rubber 18 is discharged from the tip portion 17.

二軸押出機１１から排出された練りゴムの粘度を、粘度測定装置によりオンラインで測定して定量供給装置１２にフィードバックさせ、定量供給装置１２において、定量供給装置１２から二軸押出機１１に供給するノンプロ練りのペレットゴムとプロ練り薬品との供給量を、図１に示す相関関係に基づいて調整する。例えば、ゴムの粘度の目標値を定め、ゴムの粘度の目標値との差分からゴムの供給量を調整する。供給量を調整することによって、二軸押出機１１内の充填率（ゴム密度）を変化させ、単位重量当たりのゴムが受けるせん断エネルギーを制御する。二軸押出機１１内には空隙があり、充填率（ゴム密度）は８〜１５％である。さらに図中右側に向かって軸方向に押出されることによって連続的に混練が行われる。そして、シリンダ１５の先端部１７からは、ゴム原材料の粘度バラツキの影響を受けない、常に安定した一定粘度の練りゴム１８が排出される。   The viscosity of the kneaded rubber discharged from the twin screw extruder 11 is measured online by a viscosity measuring device and fed back to the quantitative supply device 12, and is supplied from the quantitative supply device 12 to the twin screw extruder 11 by the quantitative supply device 12. The supply amount of the non-pro kneaded pellet rubber and the pro-kneading chemical is adjusted based on the correlation shown in FIG. For example, a rubber viscosity target value is determined, and the rubber supply amount is adjusted from the difference from the rubber viscosity target value. By adjusting the supply amount, the filling rate (rubber density) in the twin screw extruder 11 is changed, and the shear energy received by the rubber per unit weight is controlled. There are voids in the twin screw extruder 11, and the filling rate (rubber density) is 8 to 15%. Further, kneading is continuously carried out by extruding in the axial direction toward the right side in the figure. Then, a kneaded rubber 18 having a stable and constant viscosity, which is not affected by the viscosity variation of the rubber raw material, is discharged from the tip portion 17 of the cylinder 15.

なお、上述した実施の形態では、押出機に、２本のスクリューを有する二軸押出機を用いたが、本発明は、二軸押出機に限るものではなく、スクリューが２本以上の複軸押出機を用いることも可能である。   In the above-described embodiment, the twin screw extruder having two screws is used as the extruder. However, the present invention is not limited to the twin screw extruder, and a double screw having two or more screws. It is also possible to use an extruder.
