ることができるようになっている。2. Description of the Related Art Generally, in a kneading machine such as a kneader or Banbury, which is used for kneading a material to be kneaded such as rubber or plastic, the material to be kneaded is filled inside. With a mixing tank that is rotatably provided in the mixing tank, a rotor that can knead the material to be kneaded that is filled in the mixing tank when rotating, and a rotor that can enter and leave the mixing tank, It comprises a ram capable of pressing the object to be kneaded filled in the mixing tank toward the rotor at the time of entry, and the ram is allowed to enter the mixing tank so that the object to be kneaded has a predetermined pressure toward the rotor. By pressing with and rotating the rotor in this state, it is possible to act on the material to be kneaded without loss of rotational energy by the rotor.

状物の生成状態によっては混練時間が長くなったり短く
なったりするため、混練時間が一定せず混練後の被混練
物の物性（粘度等）にばらつきが生じてしまう。However, in the conventional hermetic kneader constructed as described above, since the ram continues to press the object to be kneaded during the kneading, the object to be kneaded stays between the ram and the rotor. Then, a lid-like object may be generated in that part,
Since such a lid-like material hardly moves during the kneading and stays in the same place, the kneading state of the material to be kneaded becomes uneven. Therefore, normally, the kneading is continued until the lid-like material is destroyed, and the kneading state of the material to be kneaded is made uniform, but the kneading time may become longer or shorter depending on the production state of the lid-like material. However, the kneading time is not constant, and the physical properties (viscosity, etc.) of the material to be kneaded after kneading vary.

路も必要となるためコスト高となってしまう。On the other hand, Japanese Patent Laid-Open No. 58-8544 discloses a method for solving the above-mentioned problem of variations in the physical properties of the material to be kneaded, which method includes ram pressure, kneading temperature,
Although the physical properties of the material to be mixed during the kneading are made uniform by controlling the power, torque value, etc. during the kneading, the overall size of the device becomes large and a complicated control circuit is also required. Therefore, the cost becomes high.

ることができない。Further, it is empirically known that a lid-like material is generated due to changes in electric power, torque value, etc. during kneading, and the lid-like material is forced by raising the ram and reversing the rotor. However, in such a method, it is largely dependent on the intuition and experience of the operator, so if the operator is inexperienced, the generation of the lid-like object is accurately detected. Therefore, the physical properties of the material to be kneaded cannot be made uniform.

ものである。The present invention solves the above-mentioned problems of the conventional ones, and determines the position of the ram in the mixing tank when the lid-like material is formed during kneading and when it is not. Data is created in advance, and based on this data, it is possible to reliably detect whether or not a lid-like material has been formed, and if it is, prevent the kneading time from increasing by forcibly destroying the accumulated material. Therefore, it is an object of the present invention to provide a hermetic kneading machine and a kneading method capable of achieving uniform physical properties (viscosity and the like) of a material to be kneaded after kneading.

きることになる。In this case, in advance, the mixing tank 2 during kneading.
The position of the ram 4 inside and the rotational torque of the rotors 3, 3.
The relationship between the electric power value and the kneading temperature will be examined separately for the case where the lid-shaped material 9 is generated and the case where it is not generated. That is, when the lid-like material 9 is not generated, the ram 4 enters the mixing tank 2 at a constant speed as the kneading progresses, and the kneading ends when the lowest point is reached. . On the other hand, when the lid-like object 9 is generated, the ram 4 does not enter the lowest point at a constant speed and stays in the middle, and accordingly, the rotor 3,
The rotational torque and electric power value of 3 also change (become lower than usual). Therefore, by obtaining these data in advance, it is possible to reliably detect whether or not the lid-like material 9 is generated in the mixing tank 2 only by detecting the position of the ram 4.

混練物８を所定の圧力で押圧し、混練を続ける。The position of the ram 4 in the mixing tank 2 during kneading based on the above data is used as the displacement sensor 1.
When the entry speed of the ram 4 into the mixing tank 2 changes, it is determined that the lid-like object 9 is generated, and the air cylinder 6 is operated to move the ram 4 out of the mixing tank 2. At the same time, the air cylinder 6 is actuated to cause the projecting member to project into the mixing tank 2, and the lid 9 generated in the mixing tank 2 is impacted and destroyed, and the air cylinder 6 is actuated again after the destruction is completed. Then, the projecting member 5 is withdrawn from the mixing tank 2 and the ram 4 is again introduced into the mixing tank 2 to press the object to be kneaded 8 with a predetermined pressure to continue the kneading.

きる。Thus, the kneading operation of the object 8 to be kneaded can be made uniform by carrying out the kneading operation while successively judging whether or not the lid-like object 9 is generated by the signal from the displacement sensor 10. In addition, the kneading time can be shortened by forcibly destroying the lid-shaped material 9.

Description of the Related Art Generally, in a closed kneader such as a kneader or a Banbury used for kneading a material to be kneaded such as rubber or plastic, the material to be kneaded is filled inside. With a mixing tank that is rotatably provided in the mixing tank, a rotor that can knead the material to be kneaded that is filled in the mixing tank when rotating, and a rotor that can enter and leave the mixing tank, It comprises a ram capable of pressing the object to be kneaded filled in the mixing tank toward the rotor at the time of entry, and the ram is allowed to enter the mixing tank so that the object to be kneaded has a predetermined pressure toward the rotor. By pressing with and rotating the rotor in this state, it is possible to act on the material to be kneaded without loss of rotational energy by the rotor.

物の物性（粘度等）にばらつきが生じてしまう。However, in the conventional hermetic kneading machine constructed as described above, the kneading object is kept pressed by the ram during the kneading, so that the kneading object stays between the ram and the rotor. Then, a lid-like object may be generated in that part,
Since such a lid-like material hardly moves during the kneading and stays in the same place, the kneading state of the material to be kneaded becomes uneven. Therefore, normally, the kneading is continued until the lid-like material is destroyed, and the kneading state of the material to be kneaded is made uniform, but the kneading time may become longer or shorter depending on the production state of the lid-like material. However, the kneading time is not constant, and the physical properties (viscosity, etc.) of the material to be kneaded after kneading vary.

ものである。The present invention solves the above-mentioned problems of the conventional ones, and determines the position of the ram in the mixing tank when the lid-like material is formed during kneading and when it is not. Data is created in advance, and based on this data, it is possible to reliably detect whether or not a lid-like material has been formed, and if it is, prevent the kneading time from increasing by forcibly destroying the accumulated material. As a result, the physical properties (viscosity, etc.) of the material to be kneaded after kneading can be made uniform.
An object is to provide a closed kneader and a kneading method.
