Conveyor belt specification determining method
First Claim
1. A conveyor belt specification determination method, comprising:
- categorizing, into a plurality of categories, a severity of use conditions of a conveyor belt, using a horizontal energy and a vertical energy as indices, the horizontal energy and vertical energy being received by the conveyor belt as a result of objects to be conveyed being fed onto and loaded on an upper cover rubber of the conveyor belt and conveyed;
creating a database in which a permissible range of each of prescribed characteristics is set for each of the categories, the prescribed characteristics including at least wear resistance and cut resistance of the upper cover rubber;
setting a representative rubber physical property of the upper cover rubber that affects each of the prescribed characteristics;
ascertaining a degree of influence of the representative rubber physical property that is set on the prescribed characteristics;
when determining a specification of the conveyor belt, identifying the category of severity from the use conditions of the conveyor belt on a basis of the database;
identifying an appropriate range of the representative rubber physical property for which the prescribed characteristics are in the permissible range in the category that is identified; and
selecting a rubber type, for which the representative rubber physical property is in the appropriate range that is identified, as the upper cover rubber.

Abstract
Provided is a conveyor belt specification determination method. Severity of a use condition of a conveyor belt is categorized into categories. A database in which a permissible range of prescribed characteristics of an upper cover rubber, including wear resistance and cut resistance, for each of the categories is set is created; a degree of influence of representative rubber physical properties, which affect the prescribed characteristics, of the upper cover rubber on the prescribed characteristics is ascertained; a category is identified from the use conditions of the conveyor belt on the basis of the database; an appropriate range of the representative rubber physical property is identified for which the prescribed characteristics are in the permissible range in the identified category; and a rubber type for which the rubber physical properties are in this appropriate range is selected as the upper cover rubber.
