Method and system for inspecting quality of unvulcanized rubber material, and method and system for manufacturing unvulcanized rubber material

Abstract

Provided are: a method and a system which are for inspecting the quality of an unvulcanized rubber material, and with which it is possible to quickly determine, in a non-destructive manner and in greater detail, whether or not the quality of the unvulcanized rubber material is acceptable; and a method and a system which are for manufacturing an unvulcanized rubber material, and with which it is possible to produce, with high productivity, an unvulcanized rubber material that is obtained by mixing a prescribed type of compounding agent in an appropriate blending proportion with respect to an unvulcanized rubber. The present invention involves: detecting, by using a final dielectric constant measuring instrument 5b, a dielectric constant of a final rubber material R2 that is obtained by mixing a prescribed type of a compounding agent As with an unvulcanized rubber M; calculating, on the basis of the detected dielectric constant, a compounding proportion D for the compounding agent As inthe final rubber material R2 by means of an arithmetic device 6; determining whether the calculated compounding proportion D1 falls within or outside a preset compounding reference range C1, and displaying the determination result on a monitor 8; and adjusting the proportion of the compounding agent As with respect to the unvulcanized rubber M to be fed into an extruder 4 so as to make the calculated compounding proportion fall within the compounding reference range C1.

Description

technical field [0001] The present invention relates to an unvulcanized rubber material quality inspection method and quality inspection system, and an unvulcanized rubber material manufacturing method and manufacturing system. Background technique [0002] When producing rubber products such as tires, there is a process of kneading unvulcanized rubber and compounding ingredients using a mixer (mixer) or a rubber extruder to produce an unvulcanized rubber material. In this manufacturing process, compounding ingredients are added to unvulcanized rubber at a predetermined compounding ratio. If the compounding ratio of the actually added compounding ingredients deviates from the reference range, the quality of the produced unvulcanized rubber material will be affected. Furthermore, it affects the quality of rubber products manufactured using the unvulcanized rubber material. [0003] Conventionally, the aerobic flask combustion method and the sodium peroxide melting method ar...

AI Technical Summary

Problems solved by technology

In this proposed method, although the presence or absence of pollutants in the unvulcanized rubber material and the relative change in content can be grasped based on the attenuation of the intensity of ultrasonic waves, it does not determine whether the compounding ratio of the compounding agent in the unvulcanized rubber material is appropriate.
