Slip-free braking algorithm for belt conveyors

This article continues a series of research publications on starting and braking duties of a belt conveyor. Starting and braking of belt conveyors are accompanied with extra dynamic stresses in belts, which may lead to the unstable operation of driving drums, slippage of belts, pitch instability of belts, etc. The main objective of the research is formulation of an optimum braking algorithm. The algorithm must ensure maintenance of traction in operation of a conveyor in a dynamic mode. The belt is the most expensive part of a conveyor facility. Owing to stabilization of traction, reduction of belt safety factor and decrease in the belt wear, it is possible to reach essential enhancement in the efficiency of conveyors. The main research method is mathematical modeling using advanced software systems. The key idea of the proposed algorithm is the preliminary braking of the tail drum and the additional adjustment of the traction factor to eliminate the belt sagging between roller supports, which can minimize the belt slip on the driving drum, substantially cut-down the time of the drive halt, and, accordingly, reduce the period of potential slip to appear. The calculation procedure of the braking process variables uses the relations and dependences found during the research, as is structured so that to be applicable to any conveyor of a certain class, namely, to the single-belt horizontal motion conveyors with trough belts and upper carrying side.
