Title: CONVEYOR BELT HAVING PREDICTABLE SERVICE LIFE
Abstract:
The present invention relates to a conveyor belt having a predictable service life and, more particularly, to a new-concept technology not only for enabling anyone to easily check the degree of wear of a conveyor belt with the naked eye without having to suspend the operation of a conveyor line, such that the time to replace the same can be easily recognized in advance, but also for predicting/managing the life of the conveyor belt. Conventionally disclosed conveyor belts have the following problems: it is impossible to recognize in a stepwise manner the extent to which wear has progressed and to predict the life accordingly; troughs are not formed well; and the trough angles are inevitably small, causing leakage of carried objects. In an attempt to resolve the above problems, the present invention is characterized by conceiving of a technology wherein, as the wear of a conveyor belt progresses, wear-marking colored rubbers installed inside the conveyor belt are exposed to the outside such that, simply by checking the same with the naked eye, the degree of wear of the conveyor belt can be recognized, making it possible to predict the time to replace the same. The wear-marking colored rubbers are installed in multiple stages such that the number thereof decreases toward the lower portion, making it possible to predict the life of the conveyor belt in a stepwise manner by recognizing the number of exposed wear-marking colored rubbers.
