No power roller conveyor , also known as roller . There are long and short roller roller two kinds . Long roller surface shape of a roller having a cylindrical , conical and curved several order -cylindrical roller most widely used. Roller curve segments using double cylindrical or conical rollers rollers can turn items . Short roller can shorten the distance between the rollers , lighter weight . Roller generally slightly down-dip , when the goods heavier, longer lines , time and effort in order to promote goods , the slope desirable one to 1.5%. To make articles from sliding , the slope can be increased to 2 to 3%. Since the slippery slope affect the size of many factors, mostly with experiments to determine the appropriate angle. When the line length is less than 10 meters, when the article lighter than 200 kg , can be arranged in horizontal lines. Since the sliding roller items difficult to control the rate of decline , so the length is generally small. Roller width than the width of items 100 to 150 mm. The minimum radius of curvature of the curve segment roller 3 to 4 times the width . Goods transport roller spacing length 1/ 3 to 1 / 4, when the article transport require a higher smoothness . Preferably the length of conveying goods pitch 1/ 4 to 1 /5 . Roller diameter determined by the size of the load . No power roller conveyor , also known as roller .
