Examples of modular conveyors operable along curved paths are found in the following united states patents. u.s. pat. no. 5,174,439 disclosed a conveyor having a high percentage of open area and link element clearances for cleanability and flow-through and for maximizing collapsed link clearances during turning on curves to prevent build-up of foreign material on the conveyor.
Feb 07, 2017 curve conveyors for flexible layouts. like many things in life, industrial material handling often has its share of twists and turns. modern manufacturing, food and beverage processing, packaging, and other industries which rely on conveyors, frequently require systems capable of accommodating tight curves — sometimes as much as 90 or even 180 degrees — in order to.
Feb 21, 2002 ribeneke (structural) 27 jan 02 01:41. when your belt lifts off the slider bed, it will be a catenary with shape y = c * cosh (x/c), because it has typically a uniform mass per slope length. the constant c is related to t0 (catenary tension at the horizontal portion) and w.
Figure 9.3 recommended minimum radii for concave vertical belt conveyor curves. to insure that the belt tension is sufﬁciently high to avoid zero tension in the belt edges at a concave curve, a check of the curve radius should be made by the use of the following formula for fabric constructions:.
Idlers or bend pulleys on convex (hump) curves along the return side have extra pressure due to component of the belt tension and are therefore effective training locations. carrying side self aligners should not be located on a convex curve since their elevated.

Oct 03, 2015 a conveyor belt profile that can be used on a single, long, overland conveyor is often with several convex and concave curves. on such conveyors, it is essential that belt tensions be determined along the entire length in order to calculate the radii of the curves and locate the maximum belt tension which can occur at an intermediate.
On a conveyor with a curve, the scale should be installed at a location where the curve does not influence the scale performance. curves can be concave or convex as shown in fig. 6. if the con-veyor has a concave curve, the curve will have a lifting effect on the belt in the area of the curve. if this lifting effect occurs in the scale area it.
