BELT CONVEYOR DEVICE AND EXPANSION AND CONTRACTION METHOD OF BELT CONVEYOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a belt conveyor device that can expand and contract a conveying distance for an article to be conveyed in a short time when the article to be conveyed is sandwiched by two belts and conveyed in an upward and downward direction.;SOLUTION: The belt conveyor device 1 includes: a conveying belt 2 for sandwiching the article to be conveyed by the first belt 2A and the second belt 2B, and conveying it in an upward and downward direction; a frame member 3 to which the conveying belt 2 is provided; and a tension applying mechanism 33 for applying tension to the conveying belt 2 by the first carrier roller 35A for displacing the conveying belt 2 in the first direction that intersects with the first belt 2A, and the second carrier roller 35B for displacing the conveying belt 2 in the second direction opposite to the first direction. The frame member 3 is formed by connecting a plurality of conveying device units 31 that can be attached to and detached from each other. The conveying device units 31 are provided with the tension applying mechanism 33, and the conveying distance of the article to be conveyed can be expanded and contracted in a short time by attaching and detaching the conveying device units 31.;COPYRIGHT: (C)2013,JPO&INPIT
