Method for joining conveyor belt

Abstract

Provided is a method that is for joining a conveyor belt having a canvas layer as the core body and that, at the ends in the lengthwise direction of the conveyor belt, can increase the quality of the join and reduce the joining work time. The core body (1a) formed from a laminated canvas layer (1b) at the ends (1A) in the lengthwise direction of the belt main body (1) is formed ahead of time into a stepped shape; the top of the core body (1a) formed into the stepped shape is covered by a peeling member (3); in the state of a cover rubber (4) being laminated on the peeling member (3), the belt main body (1) is vulcanized / molded; and when joining the ends (1A) in the lengthwise direction of the belt main body (1), the peeling member (3) is peeled off, eliminating the cover rubber (4) laminated onto the peeling member (3) and exposing the core body (1a) formed in a stepped shape, and the other core body formed into a stepped shape and that is to be joined to the exposed core body (1a) is caused to face and be laminated thereto, and the result is vulcanized and joined.

Description

technical field [0001] The present invention relates to a method of joining a conveyor belt having a core formed by laminating a plurality of canvas layers. More specifically, the present invention relates to a joining method of a conveyor belt capable of reducing the time required for joining the longitudinal ends of the belt and improving the quality of the joint. method. Background technique [0002] A conveyor belt having a canvas layer as a core is stretched between driving rollers and driven rollers provided at the front and rear of the belt conveyor. And, it is supported by a plurality of guide rollers arranged between the driving roller and the driven roller. After a certain period of use and / or in the case of damage during use, the entire conveyor belt is replaced, and / or the damaged part is cut off and a new conveyor belt is attached to the longitudinal end of the belt body ( For example, refer to Patent Document 1). [0003] Such belt replacement work and / or re...

AI Technical Summary

Problems solved by technology

At the site where the conveyor belt is used, there are restrictions in terms of work space and / or processing equipment, so there is a problem that a lot of time is required for joining work

[0010] In addition, during this joining operation, the canvas layer may be unnecessarily damaged by the cutting tool, and the position of the canvas layer may be displaced.

Therefore, in order to ensure the quality of the joint portion of the conveyor belt, the operator who performs the joint work is required to have a high level of technology.
