Conveyor belt and drive belt comprising knitted belt, and conveyor device using conveyor belt

摘要

(PROBLEM) To provide a seamless conveyor belt comprising knit fabric.;(SOLUTION MEANS) A seamless conveyor belt employing monofilament made up of continuous fiber at filament constituting core yarn; being made up of weft-knit or warp-knit in which there is mutual intertwining of filament; flexural stress and heat causing monofilament at core yarn to undergo plastic deformation at locations of entanglement; being a seamless knit belt (1a) comprising a knit pattern (8) which is weft-knit or warp-knit; being a knit pattern (8) in which pitch (Ps) of stitch loops in a width direction (18) is smaller than pitch (Pg) of stitch loops in a conveying direction (17) of the seamless knit belt; mutually contacting loops (9) and filament undergoing deformation; entangled regions of filament being maintained; fraying at side ends of the knit belt (1a) during conveyance by the conveyor belt being prevented; spacing of pitch (Ps) of stitch loops in the width direction (18) being small; and strength being improved.

主权项

1. A seamless conveyor belt, comprising:
a seamless knit belt including knit fabric, which is weft-knit or warp-knit, the knit fabric comprising knitting yarn including core yarn which is a monofilament made up of continuous fibers, and in which there is mutual intertwining of filaments; wherein the knit fabric includes knit stitches in the form of loops, and dimensions of adjacent loops in a gauge direction, which is a conveying direction, are different sizes, wherein the knit fabric has a knit pattern in which a pitch Ps of loops in a stitch direction, which is an axial direction, is smaller than a pitch Pg of loops in the gauge direction, wherein loops at knit stitches coming in mutual contact in the conveying direction have stitch loops which are small loops and large loops, wherein the knitting yarn undergoes plastic deformation of filaments at locations where the filaments are entangled causing an entangled state to be maintained at filament of loops; wherein slack, which is an amount of looping, at the large loops is small, and wherein small loops approach, or come in contact with, knitting yarn in the belt width direction, which is the stitch direction, wherein fraying of yarn due to rubbing at side ends and breakage of yarn at mutual monofilament locations due to abrasion during driving or conveying of the belt being prevented even where there is plastic deformation of mutually intertwined filament, and wherein pitch spacing in the stitch direction is shortened; and strength in the conveying direction, which is the drive direction, is improved.
