LOAD WEIGHING METHOD AND DEVICE IN PNEUMATIC FLOAT TYPE BELT CONVEYOR

摘要

PROBLEM TO BE SOLVED: To weigh a load and also its momentary charge and confirm and monitor loaded condition. SOLUTION: An air pressure P generated between a belt B and a belt travel surface 1a in the position of three or more places in the circumferential direction of the belt travel surface 1a is measured, thereby seeking the pressure distribution in the lateral direction of the best, and the vertical component Pcosθ(θis a tilt angle from the vertical direction) of the air pressure P in the pressure distribution is integrated in the lateral direction of the belt, and the integral value∫Pcosθ.rdθ(r is the radius of a cylindrical tube of forming a travel surface) is sought as the weight of a load including the belt.
