METHOD OF CONTROLLING THE CONVEYOR TAPE SPEED Russian patent published in 2016 - IPC B65G43/08 

FIELD: machine building.

SUBSTANCE: conveyor tape speed control method involves measurement of tape speed and the q_in incoming cargo traffic, tape speed change by conveyor drive control. Tape speed is measured at the point of loading and one of the following actions is performed: tape speed is increased by the q₁ value/ψ during time Δt₁, if the q_in incoming cargo traffic exceeds the q_out conveyor receiving capacity, where q₁ is the ratio of nominal efficiency of the conveyor to the selected number of tape speed control stages at increased speed, ψ - nominal linear load; tape speed is decreased by the q₂ value/ψ during time Δt₂, if the q_in incoming cargo traffic is less than the q_out conveyor receiving capacity by the q₂ value, where q₂ is the ratio of nominal efficiency of conveyor to the selected number of tape speed control stages at decreased speed; tape speed is left without changing, if the value of the q_in incoming cargo flow is in the range of values of q_out-q₂ up to q_out; conveyor loading is stopped without changing the tape speed if the q_in incoming traffic exceeds the q_max conveyor maximum receiving capacity.

EFFECT: efficiency of conveyor operability is increased.
